Bouncing baby chair

Abstract

A bouncing baby chair comprising a seat assembly supported by a frame and a resilient biasing device provides a bouncing motion which parents or other caretakers may use to soothe a colicky baby. The baby chair provides a bouncing motion which is substantially vertical that is soothing without creating or exacerbating a baby's digestion problems. The baby chair also supports a parent in a seated position on a seat assembly which reduces fatigue. In one embodiment, the seat assembly is supported by one or more resilient biasing devices. The seat assembly may bounce by moving downward distorting the resilient biasing device and upward assisted by the biasing device returning to a substantially undistorted state. The soothing bouncing motion may be produced by repeating these motions on the bouncing baby chair.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates generally to seating and in particular to a bouncing baby chair that allows parents to soothe agitated babies.

2. Related Art

As is known, a colicky or agitated baby can be difficult to soothe, and may cry, scream, or both for long periods of time. It is believed that one possible cause of colic is abdominal pain or abdominal gas related to digestion. Various remedies such as changes in diet or administration of digestion aids have been used to reduce or “treat” colic. However, it is often difficult or impossible to determine what changes in diet will work. In addition, administration of medical treatment such as probiotics may be undesirable for parents and their baby.

One less invasive remedy that has been shown to soothe colicky babies is gentle rocking of the baby. Though not as drastic as changing the baby's diet or medical treatment, rocking is not effective all the time. In addition, the rocking motion may cause the baby to have acid reflux which causes further agitation to the baby. Further, rocking may be tiring for sleep-deprived parents, especially when a baby is agitated for an extended period.

From the discussion that follows, it will become apparent that the present invention addresses the deficiencies associated with the prior art while providing numerous additional advantages and benefits not contemplated or possible with prior art constructions.

SUMMARY OF THE INVENTION

A bouncing baby chair for soothing agitated or colicky babies is provided herein. The bouncing baby chair provides a bouncing motion which soothes babies that cannot otherwise be calmed. Unlike rocking or other motions, the bouncing motion does not cause or exacerbate a baby's digestion problems. The baby chair also provides support for a parent's body in a seated position which reduces parental fatigue.

In one embodiment, the baby chair comprises a frame and a seat assembly supported within the frame. The frame may comprise two trapezoidal side supports having a closed top portion and an open bottom portion, one or more lower cross members extending between the trapezoidal side supports at a bottom end of the trapezoidal side supports, one or more upper cross members extending between the trapezoidal side supports at a top end of the trapezoidal side supports, the one or more upper cross members at a rear of the baby chair.

The seat assembly may comprise a seat configured to accept a user in a seated position, a backrest configured to support a user's back, and a seat frame comprising an upper frame and a lower frame. The lower frame may be configured to support the seat, and the upper frame may extend upward from a front end of the lower frame and towards a back end of the lower frame. A back portion of the upper frame may support the backrest. One or more resilient biasing devices may be between the seat assembly and the frame. The resilient biasing devices may be attached at a first end to the frame and attached at a second end to the seat assembly such that the seat assembly may bounce within the frame while attached to the one or more resilient biasing devices.

The resilient biasing devices may be attached at the first end to the upper cross member of the frame. In addition, the resilient biasing devices may be one or more resilient biasing devices of a first strength and one or more resilient biasing devices of a second strength. Also, the supports of the first strength may be at a front portion of the seat assembly while the supports of the second strength may be at a rear portion of the seat assembly. The resilient biasing devices may be springs.

One or more wheels at the bottom end of the trapezoidal side supports may be provided to allow the baby chair to be easily moved. In addition, the backrest and seat may be formed from a single rigid material.

In one embodiment, the baby chair comprises a seat frame comprising an upper frame and a lower frame with the lower frame extending upward and back from a front portion of the lower frame. A seat may be attached to the lower frame and a backrest attached to the upper frame. The upper frame of the seat frame may be curved to form one or more curved armrests. The baby chair may also include one or more side supports having a closed top portion and an open bottom portion, and one or more armrests formed by a portion of the upper frame between the backrest and the seat. The side supports may also be completely closed in some embodiments. Also, the side supports may be trapezoidal in shape.

One or more upper cross members may extend between the one or more side supports at a top end of the one or more side supports. The one or more upper cross members may be at a rear portion of the one or more side supports, and may be longer than the width of the seat to allow the seat to fit between the one or more side supports. One or more lower cross members may extend between the one or more side supports at a bottom end of the one or more side supports.

One or more rear resilient biasing devices attached at a first end to the one or more upper cross members and at a second end to the lower frame of the seat frame, and one or more front resilient biasing devices attached at a first end to the one or more side supports and at a second end to the lower frame of the seat frame at the front portion of the lower frame may be provided as well. It is noted that the baby chair may only have one rear resilient biasing device in some configurations. The resilient biasing devices configured to allow the user to bounce when seated on the baby chair. The front resilient biasing devices may be of a first strength and the rear resilient biasing devices of a second strength. In some embodiments, the front resilient biasing devices and the rear resilient biasing devices comprise covered springs.

A method of soothing a baby at a bouncing baby chair is also provided. In one embodiment, the method comprises accepting a user carrying a baby on a seat assembly of a baby chair. The seat assembly may comprise a seat frame supporting a seat and a backrest of the seat assembly with an upper frame of the seat frame forming one or more armrests. The method may also include supporting the user's weight with the seat, supporting the user's back with the backrest, and bouncing the seat assembly in an up and down motion within a frame of the baby chair to soothe the baby. The frame may comprise two side supports having a closed top portion and an open bottom portion, and the seat assembly may be attached to the frame by one or more resilient biasing devices.

The bouncing baby chair may be moved from one location to another on one or more wheels attached at a bottom end of the bouncing baby chair. The user's arms may be supported on an armrest formed by an upper frame of the seat frame. Physical contact with the one or more resilient biasing devices may be prevented with the closed top portion of the two side supports to increase safety. For example, physical contact with the resilient biasing devices may be prevented with one or more tubular covers surrounding the resilient biasing devices.

Other systems, methods, features and advantages of the invention will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description, be within the scope of the invention, and be protected by the accompanying claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following description, numerous specific details are set forth in order to provide a more thorough description of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without these specific details. In other instances, well-known features have not been described in detail so as not to obscure the invention.

The bouncing baby chair herein allows parents to soothe a colicky baby through a gentle bouncing motion. This is advantageous in that bouncing may be effective in soothing a colicky baby where rocking or other remedies have not been effective. Also, in contrast to a traditional rocking motion, the bouncing motion provided by the bouncing baby chair does not exacerbate the problem by causing acid reflux or other digestive problems. The bouncing baby chair allows this gentle bouncing motion to be easily generated with little strain on parents.

In one or more embodiments, the bouncing baby chair supports a parent and his or her baby. The parent may then soothe the baby with the baby in his or her arms and in a generally seated position. This is less burdensome on the parent who may ordinarily rock the baby with his or her arms while standing or sitting. Without an aid, a parent would typically have to gently bounce the baby with his or her own strength. This can be tiring especially when a parent is already sleep-deprived or when a baby is colicky in the middle of the night or early in the morning.

As will be described further below, the bouncing baby chair generally provides a resilient biasing device which allows a bouncing motion to be easily generated by a parent. In one or more embodiments, the baby chair allows a parent to gently bounce with a baby in his or her arms while in a generally seated position. The baby chair may support the parent's and the baby's weight, and in some embodiments, a back support may be provided to support the parent's back. It is noted that though described herein with regard to a baby's parents as users of the chair, any caretaker or other person may utilize the baby chair.

The bouncing baby chair will now be described with regard to the figures. FIG. 1A is a side view illustrating an embodiment of the bouncing baby chair. As shown, the baby chair comprises a frame 104 at its lower end and a seat assembly 108 at its upper end. In general, the seat assembly 108 rotates about a pivot 116 of the frame 104. A bouncing motion may then be provided by a resilient biasing device 112 which provides a force that dampens or resists downward movement of the seat assembly 108. The force provided by the resilient biasing device 112 also returns the seat assembly 108 upward. In this manner, the baby chair's seat assembly 108 provides a bouncing motion for soothing an agitated baby.

In general, the frame 104 of the bouncing baby chair supports the other components of the baby chair as well as any users of the baby chair. The frame 104 will typically be formed from one or more rigid materials and may include one or more braces 140 to provide a structure capable of supporting the components of the baby chair as well as any users of the chair.

In the embodiment shown, the frame 104 has a base 120 which stabilizes the bouncing baby chair relative to the floor. The base 120, or a portion thereof, may contact the floor to perform this function. The base 120 may comprise one or more elongated members, such as shown, or other structures. For example, the base 120 may comprise one or more planar or other shaped portions in some embodiments.

A riser 124 of the frame 104 may extend upward from the base 120 to support the seat assembly 108 of the bouncing baby chair. This allows the seat assembly 108 to be supported at an elevated position which allows a user to be in a seated position when using the baby chair. The riser 124 may be reinforced by one or more braces 140 such as shown in FIG. 1A or may be configured to be sufficiently strong without any bracing.

As shown, the riser 124 comprises one or more elongated members or structures. It is noted that, like the frame 104, other configurations may be used. In addition, it is contemplated that the frame 104 and riser 124 may be integrally formed. For example, in one embodiment, the frame 104 and riser 124 may be combined in a generally triangular structure where the riser is formed by the elevated portion of the triangular structure. The slope of the triangular structure may include one or more angles, curves, or both to accommodate a resilient biasing device 112.

A pivot 116 may be provided in one or more embodiments to allow the seat assembly 108 to move in a bouncing motion. In general, a pivot 116 allows the seat assembly 108 to rotate about a substantially horizontal axis. This allows the seat assembly to provide a substantially vertical bouncing motion to a parent and baby, as shown by the arrows in FIG. 1A. The pivot 116 may attach to an end or other portion of the seat assembly 108.

The pivot 116 may be located at an upper end of the riser 124. For example, as shown, a pivot 116 may be provided at the top of the riser 114. It is contemplated that the pivot 116 may also be located on other locations of the riser 124. This is beneficial because it allows the angle of the seat assembly 108 to be adjusted as desired. For example, a pivot 116 at generally the same height as the top of a resilient biasing device (as will be discussed below) may cause the seat assembly 108 to be positioned generally parallel to the ground. A pivot 116 lower or higher than the top of a resilient biasing device will typically cause the seat assembly 108 to be in an angled or tilted position. Alternatively or in addition, it is contemplated that a series of pivots 116 may be located along the riser 124 to allow the seat assembly 108 to be repositioned. This allows the baby chair's bouncing motion to be adjusted for different users and babies.

The pivot 116 itself may comprise any structure or device, now known or later developed, which rotatably secures a seat assembly. For example, a hinge may be used as a pivot 116 in one or more embodiments. In other embodiments, the pivot 116 may comprise an axle fitted through one or more openings or axle mounts in the seat support 144 and the arm 124. It is noted that one or more pivots 116 may be provided in some embodiments. For example, as shown, one pivot 116 supports one side of the seat assembly while another pivot supports the other side of the seat assembly 108.

The seat assembly 108 itself may comprise a seat 128 which allows a parent to sit on the seat assembly. The seat 128 typically forms the bottom of a seat assembly 108. In addition, a portion of the seat 128 may be used to secure or attach the seat assembly 108 to the pivot 116. This allows the seat assembly 108 to rotate about the pivot 116.

The seat assembly 108 may also comprise a backrest 132 in one or more embodiments. As can be seen, the backrest 132 may extend upward from the seat 128 to support a user's back. This reduces strain on the user and provides additional comfort when using the bouncing baby chair. The backrest 132 may extend at various angles, and may have an adjustable angle in one or more embodiments. In addition, it is contemplated that a backrest 132 may be removable in some embodiments. It is noted that the angle of the backrest 132 may determine which direction a parent faces when seated in the bouncing baby chair.

In one or more embodiments, the seat assembly 108 may include one or more pads 136 to increase user comfort. For example, the bouncing baby chair may provide a padded seat bottom and/or backrest. To illustrate, in FIG. 1A, the seat assembly 108 has a pad 136 on the seat 128 and a pad for the backrest 132. It is noted that a seat assembly 108 may include other elements for better ergonomics or comfort. For example, as described below, a seat assembly 108 may include one or more armrests.

As stated above, one or more resilient biasing devices 112 provide a biasing force which allows and assists in moving the seat assembly 108 in a bouncing motion. Typically, the resilient biasing device 112 will be positioned beneath a portion of the seat assembly 108. This allows the resilient biasing device 112 to support and apply its biasing force to the seat assembly 108. For example, a resilient biasing device 112 may be beneath a portion or end of the seat assembly not supported by the pivot 116, as shown. In one or more embodiments, the seat assembly 108 may be supported at a first end by the pivot 116, and at a second end by the resilient biasing device 112. It will be understood that the resilient biasing device may be positioned at various points beneath the seat assembly 108 to support the second end.

In general, the resilient biasing device 112 dampens or resists downward motion of the seat assembly 108 and provides an upward force which causes the seat assembly to return in an upward direction. The resilient biasing device 112 may also limit the range of motion of the seat assembly 108 in some embodiments. For example, the resilient biasing device 112 may prevent the seat assembly 108 from moving downward past a certain point.

In one embodiment, the resilient biasing device 112 comprises a resilient sphere such as shown in FIG. 1A. Moving the seat assembly 108 downward compresses the sphere while moving the seat assembly upward allows the sphere to return to an uncompressed shape. The sphere's resistance to the downward motion dampens or resists the downward motion. The sphere's resiliency returns the sphere to a substantially uncompressed shape while applying an upward force to the seat assembly 108. In this manner, a gentle bouncing motion can be provided when the bouncing baby chair is in use.

The resilient sphere is beneficial in that it provides this bouncing motion safely. In contrast to a spring for example, there are no areas where clothing, small fingers, hands, or other body parts can get caught or pinched. In addition, the resilient sphere provides a resistance that is distinct from that of a spring in that a combination of air (or other gas) pressure and the elasticity of the sphere material determines the resistance provided, rather than a metal coil as found in a spring. The resistance of the resilient sphere may also be adjusted by inflating or deflating the sphere.

A resilient sphere may comprise an outer resilient shell which gives the sphere its substantially spherical shape. The resilient shell may be formed from various materials including but not limited to natural or synthetic rubber, plastics, or a combination thereof. In one or more embodiments, the resilient shell may be airtight to allow the resilient biasing device 112 to be filled with air or other gases. A port may be included to allow the shell to be filled with air or deflated. In these embodiments, the air allows the biasing device 112 to compress and return to an uncompressed shape such as described above. In embodiments with a port for inflating or deflating the biasing device, the pressure within the biasing device 112 may be adjusted to increase or decrease the compressibility of the biasing device. This allows the bouncing motion provided by the resilient biasing device to be adjusted. For example, inflating the resilient biasing device 112 may increase downward resistance while deflating the resilient biasing device may decrease downward resistance. Also, inflating the resilient biasing device 112 may increase the upward force provided by the resilient biasing device, while deflating the resilient biasing device decreases the upward force.

It is contemplated that the resilient shell may be of various thickness to make the biasing device 112 more or less easily compressible. For instance, a thicker shell may make the biasing device 112 more difficult to deform and increase the upward force provided by the biasing device. It is noted that this may be accomplished by reinforcing the resilient shell with flexible reinforcement such as but not limited to metal wires or bars. Of course, other materials may be used to form such flexible reinforcement. A thicker or more durable shell may also be more reliable and less easily damaged or punctured.

A resilient biasing device 112 may be held or secured beneath the seat assembly 108 in one or more embodiments. For example, in one embodiment, a resilient biasing device 112 may be secured between a portion of the frame 104 and the seat assembly 108. Securing the resilient biasing device 112 may be accomplished in various ways. For example, a resilient biasing device 112 may be secured to the frame 104, the seat assembly 108, or both by one or more fasteners, adhesives, welds, the like, or a combination thereof. In some embodiments, the resilient biasing device 112, frame 104, and seat assembly 108 or portions thereof may be shaped to secure the resilient biasing device. For example, the seat assembly 108 and frame 104 may have structures having a shape which corresponds to a portion of the resilient biasing device 112. In this manner, the resilient biasing device 112 may be secured at one end by the frame 104 and at another end by the seat assembly 108. To illustrate, in FIG. 1A, the frame 104 and seat assembly 108 have open structures or openings 144 allow a portion of the resilient biasing device 112 to be inserted therein.

FIGS. 1B-1D illustrate various openings, fasteners, mounts, or other structures which may be found on a frame, seat assembly, or both to secure a resilient biasing device. In the embodiment of FIG. 1B, a round or circular opening 144 which corresponds to the shape of the resilient biasing device 112 of FIG. 1A is provided. In the embodiment of FIG. 1C, an opening 144 is formed by elongated members (of the frame or seat assembly). In this manner, as shown, the resilient biasing device 112 is held between the frame 104 and seat assembly 108. In use, the resilient biasing device 112 is retained between the frame 104 and seat assembly 108 as it deforms and returns to a substantially undeformed shape. It is noted that a the same or a combination of various openings 144 may be utilized in the frame 104, seat assembly 108, or both.

Alternatively, or in addition, a resilient biasing device 112 may be secured by various fasteners on the frame 104, the seat assembly 108, or both such as shown in FIG. 1D. In one or more embodiments for example, the resilient biasing device 112 may be secured by hook and loop fasteners 152, holes 156 for threaded or straight fasteners which utilize friction to secure objects together, hook or loop type fasteners 148, or a combination thereof. Though shown in combination in FIG. 1D, it is noted that various fasteners may be used individually or in combination in various embodiments of the bouncing baby chair.

It is contemplated that the resilient biasing device 112 may also be shaped to be secured within a bouncing baby chair. For example, the resilient biasing device 112 may have one or more substantially planar or other shaped sections. In one embodiment, a spherical resilient biasing device 112 may have a flat or substantially flat bottom and/or top for example. The flat portion (or any other portion) of a resilient biasing device 112 may also be secured by one or more fasteners. For example, a resilient biasing device 112 may include one or more mounts which allow the biasing device to be fastened to a frame 104, seat assembly 108, or both. The mounts may be various structures such as but not limited to hooks, loops, clips, threads, ties, hook and loop fasteners, screws, and the like. In one or more embodiments, the mounts of a resilient biasing device 112 may be chosen such that they are compatible with one or more fasteners on the frame 104, seat assembly 108, or both, such as described above.

Operation of an exemplary bouncing baby chair will now be described with regard to FIGS. 2A-2C. As shown, a parent holding a baby are seated in the bouncing baby chair. A backrest is shown supporting the parent's back. However, as noted above, a backrest need not be provided in all embodiments.

In FIG. 2A, the parent and baby are seated in the bouncing baby chair. The weight of the parent and baby may compress the resilient biasing device 112 downward. Also, some bouncing may be experienced simply by sitting on the baby chair based on the resiliency of the biasing device 112. The parent may begin a bouncing motion by moving his or her body up and down.

As shown in FIG. 2B, the seat assembly 108 may be pushed or moved downward. This deforms the resilient biasing device 112 downward and causes the seat assembly 108 to rotate downward about the pivot 116. As can be seen, the downward motion is in a substantially vertical orientation for the baby. This is in contrast to a rocking which has a horizontal movement.

It is noted that the pivot 116 of the baby chair is advantageous in that it allows a downward motion to be generated in a variety of ways. For example, the parent may cause a downward motion of the seat assembly by shifting his or her weight forward or backward without having to lift his or her body weight. This reduces strain on the parent when taking care of the baby. The pivot 116 rotatably secures the seat assembly 108 allowing a shift in body weight to translate into downward motion.

As shown in FIG. 2C, the seat assembly 108 may then return upward. The upward motion may be assisted by the resilient biasing device 112. This is because the resiliency of the resilient biasing device 112 will typically tend to return the biasing device to an uncompressed or substantially uncompressed state. In doing so, the resilient biasing device 112 creates an upward force on the seat assembly 108 which assists the upward motion of the seat assembly. As can be seen, the upward motion of the seat assembly 108 causes its arm 128 to rotate about the pivot 116 similar to the downward motion. In addition, the upward motion is also substantially vertical in contrast to a rocking motion. In one or more embodiments, a parent may apply an upward or lifting force such as through his or her legs to achieve the upward return of the seat assembly 108.

By repeating the upward and downward motions, a gentle bouncing may be achieved to soothe a colicky baby. The amount of upward or downward motion may be controlled by the parent or other user by applying more or less force upon the seat assembly 108. This is beneficial in that some babies may like more bouncing rather than less bouncing, or vice versa.

The substantially vertical movement of the baby provided by the bouncing baby chair is highly advantageous. This vertical movement may soothe babies which would otherwise remain agitated by other remedies. For example, a vertical movement may be more enjoyable or soothing to a baby than a traditional rocking motion or other motion. Further, the vertical movement does not cause the baby to have acid reflux or other digestive problems which would only serve to further agitate the baby. [PROVIDE ADDITIONAL ADVANTAGES IF DESIRED]

Also, as described above, the bouncing baby chair provides elements which allow a parent to easily generate this vertical bouncing motion. This reduces fatigue on parents. In fact, the bouncing baby chair may be soothing or relaxing for both parents and babies. The parent's and baby's weight may be supported by the baby chair allowing the parent to exert less energy in soothing the baby. In addition, a backrest, if provided, greatly reduces strain on the parent's back and may be used to assist the parent's arms in holding the baby.

As will be described in the following, the bouncing baby chair may be differently configured in one or more embodiments. It will be understood that elements of a baby chair, though they may be described with respect to particular embodiments, may be used in various embodiments of the baby chair. FIG. 3 illustrates an embodiment of the baby chair that includes a stop 304. In general, the stop 304 prevents the seat assembly 108 from rotating past a certain point, as will be described further below. This embodiment also allows the parent to face the pivot 116 when seated. This is beneficial in that the parent's legs are supported when seated on the bouncing on the baby chair.

Like the above embodiments, the embodiment of FIG. 3 comprises a frame 104 and a seat assembly 108 which rotates about a pivot 116. A resilient biasing device 112 may be positioned beneath the seat assembly 108 to support the seat assembly and to assist in generating a bouncing motion. The frame 104 comprises a base 120 which may be placed in contact with the floor. A riser 124 extends upward from the base 120 and supports a pivot 116 at its top. The pivot 116 may be located at various locations on the riser 124 in one or more embodiments, as described above.

The seat 128 of the seat assembly 108 may be rotatably attached by the pivot 116 such as shown in FIG. 3. In this embodiment, the seat 128 is attached at its front end. As can be seen, this allows the parents legs to remain supported by the frame 104 and riser 124 as the bouncing baby chair is used. A backrest 132, if provided, may extend upward from the seat 128 to support a parent's back.

It is noted that in this and other embodiments, the parents may face away from or towards the pivot 116. For example, the backrest 132 may extend substantially perpendicular to the seat 128 at a central or other portion of the seat. This would allow a parent to sit facing toward or away from the pivot 116 without adjusting the backrest 132. Also, it is contemplated that the backrest 132 may be flipped, angled, or otherwise adjustable such that a parent may be comfortably seated regardless of which direction he or she desires to face when seated. For instance, the backrest 132 may be angled away from the pivot 116 such that the seated parent may recline while seated facing the pivot. The angle of the backrest 132 may dictate which direction a parent faces in one or more embodiments. Of course, a parent is free to choose which direction to face where the baby chair has no backrest 132.

The resilient biasing device 112 may be secured or held by openings 144 in the frame 104, the seat assembly 108, or both. For example, the embodiment of FIG. 3 illustrates a resilient biasing device 112 being held in place or secured by openings 144 in the frame 104 and the seat assembly 108. As discussed above however, the biasing device 112 may also or alternatively be secured by fasteners, mounts, and other devices/structures.

The stop 304 of the embodiment in FIG. 3 will now be described. As stated, the stop 304 generally prevents the seat assembly 108 from moving downward past a certain point. The stop 304 may extend upward from the base 120 of the frame 104 in one or more embodiments. In general, the stop 304 will typically be configured to physically block the movement of the seat assembly 108 thus preventing the seat assembly from moving or rotating past a certain point. As shown in FIG. 3, the stop 304 extends upward such that will contact a downward moving seat assembly 108. For example, a stop 304 may contact a portion of the seat 128 or other portion of a seat assembly 108 as the seat assembly moves downward. This contact prevents the seat assembly 108 from moving further.

The stop 304 may extend at various angles as long as it can contact a portion of the seat assembly 108. For instance, in one or more embodiments, the stop 304 may extend such that its top end will contact the seat assembly 108 to prevent further movement of the seat assembly. The stop 304 may be a rigid structure in one or more embodiments. Also, the stop 304 may also include one or more bumpers, shock absorbers, or the like. For example, in one embodiment, a shock absorber, such as a rubber or other bumper, may be positioned at the top end of the stop 304. A shock absorber is advantageous in that it prevents contact between the seat assembly 108 and the stop 304 from being abrupt or jarring which would typically disturb a baby. It is contemplated that a shock absorber may comprise one or more pistons, springs, the like, or a combination thereof in one or more embodiments.

The stop 304 is also advantageous in embodiments where the parent's legs are supported (e.g. where a parent faces the pivot when seated). This is because, in these embodiments, it may not be as easy for the parent to support the weight of the parent and the baby with the parent's legs. Thus, without the stop 304 the seat assembly 108 may rotate further downward than desired. It is contemplated that the stop 304 may be adjustable to allow the seat assembly 108 to be stopped at various locations. For example, the stop 304 may be lengthened or shortened. In addition, the angle of the stop 304 may be adjusted to stop the seat assembly 108 at different locations.

Operation of an exemplary bouncing baby chair according to this embodiment will now be described with regard to FIGS. 4A-4C. In FIG. 4A, a parent holding a baby is seated in the baby chair. As can be seen the baby chair supports the weight of the parent and baby through the seat assembly 108. The resilient biasing device 112 may compress a slight amount due to this weight. The backrest of the seat assembly 108, if provided, may support the parent's back.

In FIG. 4B, the seat assembly 108 has been moved downward. In the embodiment shown, the seat assembly 108 has moved downward by rotating about the pivot 116. This compresses the resilient biasing device 112 downward which resists or dampens the downward motion of the seat assembly 108. The seat assembly 108 may be moved downward until it contacts a stop 304 of the frame 104. When the seat assembly 108 contacts the stop 304 further downward motion of the seat assembly is prevented. This can be seen in FIG. 4B.

A shock absorber, if provided, may absorb some of the force from the seat assembly 108 when it comes into contact with the stop 304. For example, a shock absorber may be pressed inward by the seat assembly 108 to absorb this force. It is noted that the seat assembly 108 need not be moved all the way downward until contact with the stop 304 is made. For example, a bouncing motion may be achieved by moving the seat assembly 108 downward an amount which does not cause the seat assembly to contact the stop 304.

In FIG. 4C, the seat assembly 108 returns upward assisted, at least in part, by the upward force provided by the resilient biasing device 112 returning to a substantially uncompressed state. Like the downward motion, the seat assembly 108 may move upward by rotating upward about the pivot 116.

As can be seen, the upward and downward motion may be substantially vertical in this embodiment of the bouncing baby chair as well. This is generally because the pivot 116 may be configured or oriented such that the seat assembly 108 rotates about a substantially horizontal axis. As stated, this motion may be repeated as desired and generates a bouncing motion which soothes an agitated baby.

FIG. 5 illustrates an additional embodiment of the bouncing baby chair utilizing resilient cords 504 to secure the seat assembly 108 to the frame 104. In general, the resilient cords 504 allow the seat assembly 108 to be moved up and down in a bouncing motion while allowing the seat assembly to be moved in other directions as well.

Similar to the above embodiments, the frame 104 provides support to the components of the bouncing baby chair and may be placed in contact with the floor. The seat assembly 108 may comprise a seat 516 to which other parts of the seat assembly 108, such as a backrest 132 and one or more armrests 508, may be attached. The seat 516 may be similar to the seats described above, however, may include one or more structures to allow attachment of the resilient cords 504. In other words, the seat 516 may also be configured to allow the seat assembly 108 to be attached to the frame 104 of the baby chair, such as through one or more resilient cords 504 as will be described further below.

A resilient biasing device 112 may be located between the seat assembly 108 and the frame 104. The resilient biasing device 112 may be held in place or secured by one or more openings 144 in the seat assembly 108, the frame 104 or both. In the embodiment shown, the resilient biasing device 112 is secured to the seat assembly 108 by a circular opening 144 configured to accept a portion of the biasing device, while the biasing device is secured to the frame by a rectangular opening 144 which may accept another portion of the biasing device. Of course, the resilient biasing device 112 may be secured in other ways, such as the mounts and fasteners described above. It is noted that in this and other embodiments, the resilient biasing device 112 may only be secured to the seat assembly 108 or the frame 104 but not both. To illustrate, in the embodiment of FIG. 5, the resilient biasing device 112 may be sufficiently secured by the seat assembly 108 so as to not require additional fastening or securing.

As stated, one or more resilient cords 504 may be used to attach the seat assembly 108 to the frame 104. The resilient cords 504 may be formed from one or more flexible or stretchable materials. For example, a resilient cord 504 may be formed from a spring, elastic band, or the like. In one embodiment, the resilient cord 504 may be bungee cord. It is contemplated that resilient cords 504 of various size or materials may be used to attain the desired elasticity of the resilient cords.

For example, highly elastic or stretchable resilient cords 504 may be desired where a larger range of motion for the seat assembly 108 is desired. Resilient cords 504 of lesser elasticity may be used where a decreased range of motion for the seat assembly 108 is desired. The elasticity of the resilient cords 504 will typically increase or decrease the horizontal range of motion, vertical range of motion, or both of the seat assembly 108.

It is contemplated that one or more resilient cords 504 of different elasticity may be used in a single bouncing baby chair. This is beneficial in that it allows the range of motion of the seat assembly 108 to be adjusted. For example resilient cords 504 of less elasticity may be used to make it more difficult to move the seat assembly in a particular direction. In this manner, the range of motion may be limited.

A resilient cord 504 may be attached to the seat assembly 108 by one or more mounts 512. The mounts 512 may comprise various fasteners or structures. For example, a mount 512 may comprise an opening, hook, loop, clip, clamp, screw, pin, or the like. A mount 512 may also be formed by or utilize one or more adhesives, or welds. Similarly, one or more mounts 512 may be used to attach a resilient cord 504 to the frame 104. Typically, one end of a resilient cord 504 is attached to the seat assembly 108 while the other end of the resilient cord is attached to the frame 104.

A bouncing baby chair may include one or more resilient cords 504. As shown in FIG. 5 for example, the bouncing baby chair has four resilient cords 504. The resilient cords 504 are generally positioned at the edges of the seat assembly 108 and frame 104. This stabilizes the edges of the seat assembly 108 relative to the frame 104. Of course, the one or more resilient cords 504 may be positioned in other locations. In addition, additional resilient cords 504 may be used to control the range of motion of the seat assembly. For instance, a plurality of resilient cords 504 may be positioned at an edge or portion of the seat assembly 108 to control its range of motion. The combined resilient cords 504 generally have reduced elasticity as compared to a single resilient cord.

Operation of the bouncing baby chair will now be described with regard to FIGS. 6A-6C. FIG. 6A illustrates the bouncing baby chair having resilient cords 504 in use. In FIG. 6A, a parent holding a baby is seated in and supported by the seat assembly 108 and resilient biasing device 112 of the bouncing baby chair. As can be seen, the resilient cords 504 help stabilize the seat assembly 108 by generally keeping the seat assembly substantially perpendicular to the ground. Of course, the seat assembly 108 may be stabilized in other orientations as well.

In FIG. 6B, the seat assembly 108 is moved downward by the parent, compressing the resilient biasing device 112 downward. It is noted that the resilient cords 504 may be sufficiently elastic so as to not bow when the seat assembly 108 is moved downward. This allows the resilient cords 504 to continue to provide stability to the seat assembly 108 as it is moved downward. As shown in FIG. 6C, the seat assembly 108 may then be moved upward assisted by the force provided by the resilient biasing device 112 returning to a substantially uncompressed state. Like the above, the upward and downward motions of the seat assembly 108 may be repeated a bouncing motion to soothe a colicky baby.

FIGS. 7A-7D illustrate yet another embodiment of the bouncing baby chair. In this embodiment, the chair also comprises a frame 104 and a seat assembly 108. In general, the seat assembly 108 is supported within the frame 104 by one or more resilient biasing devices, such as springs which will be described further below. This allows the seat assembly 108 to generate the bouncing motion which soothes agitated babies. Typically, both the frame 104 and the seat assembly 108 will be rigid.

The seat assembly 108 may comprise a seat frame 704 configured to rigidly support a seating surface 708. As can be seen in FIGS. 7B and 7D, the seat frame 704 has members or elements which support a seat 716 as well as a backrest 712 portion of the seat assembly 108. The seat frame 704 may be formed from one or more rigid materials, such as but not limited to metal, wood, composites, and plastics. In this manner, the seat 716 and backrest 712 may be rigidly held in position when the bouncing baby chair is in use.

In one embodiment, the seat frame 704 comprises two “C” shaped frames. A lower “C” shaped frame 724 may be provided to support the seat 716 while an upper frame 720 may be provided to support the backrest 712. The upper frame 720 may be bent or otherwise shaped to form one or more armrests 508. For example, as can be seen from FIG. 7B, the upper frame 720 is bent or curved as it extends from the front of the seat assembly 108 to the rear of the seat assembly. In this manner, two armrests 508 are provided by the upper frame 720. In addition, this raises a portion of the upper frame 720 above the lower frame 724 at the rear of the seat assembly 108. This allows the raised portion of the upper frame 720 to better support the backrest 712 of the seat assembly 108. For instance, as shown in FIG. 7B, the raised portion of the upper frame 720 is near the halfway point of the backrest 712 allowing the upper frame to support the backrest.

At the same time, the lower frame 724 supports the seat 716. As can be seen, the seat frame 704 rigidly holds the seat 716 in position relative to the backrest 712 and vice versa. This provides a rigid seat assembly 108 which is capable of supporting a parent and baby. Also, the rigid seat assembly 108 prevents bouncing or other motions from being generated by the seat assembly itself. In this manner, the bouncing motion is generated by the resilient biasing devices or springs between the seat assembly 108 and frame 104. This ensures that the desired vertical bouncing motion is generated by the bouncing baby chair. The rigidity of the seat assembly 108 also provides support for the user's back when in a seated position to reduce user fatigue while caring for a baby.

It is contemplated that one or more reinforcing members, such as bars, may be added between the upper and lower frame 720,724 to reinforce the seat frame 704. For example, one or more reinforcing members may extend upward from the lower frame 724 to the upper frame 720 at the rear of the seat frame 704. Alternatively or in addition, one or more reinforcing members may extend between various portions of the upper frame 720 and lower frame 724. For example, a reinforcing member may extend under the seat 716 between the open “C” shape of the lower frame 724. It is contemplated that these reinforcing members may provide additional locations where portions of the seating surface 708 may be attached to the seat frame 704.

The seating surface 708 may comprise various materials. In one embodiment, the seating surface 708 may be comprised of planar materials, such as illustrated. In general, the materials will be rigid to support the user. It is contemplated that the seating surface 708 may be padded in one or more embodiments to increase user comfort. Portions of the seating surface 708 may also be shaped to conform to a user's body. For example, the backrest 712 may be curved or otherwise shaped to conform to the shape of a user's back. In this manner, proper back support can be provided to a user. It is noted that the seat frame 104 may also be contoured for the user's comfort. For example, as shown, the upper frame may be curved or shaped to provide a curved armrest 508 to support a user's arm.

The seating surface 708 may be attached to the seat frame 704 in various ways. For example, the seating surface 708 may be attached by adhesives, welds, fasteners, or the like. One or more additional attachments may be used as well, such as brackets or other structures. As shown in FIG. 7A for example, the seat 716 of the seating surface 708 is attached at least in part by a bracket 728. Examples of fasteners that may be used include nuts, bolts, screws, and pins.

Referring now to FIGS. 7A and 7C, the frame 104 may comprise one or more side supports 732 which may be held apart by one or more cross members 736. In general, the cross members 736 are sized to allow the seat assembly 108 to fit between the side supports 732. In this manner, the seat assembly 108 can be supported within the frame 104. As shown, the frame 104 comprises three cross members 736, two of which are at a lower portion of the frame and one of which is at an upper portion of the frame. The lower cross members 736 form a portion of the base of the bouncing baby chair which keeps the chair stable on the ground or floor. The upper cross member 736 helps prevent the side supports 732 from tilting or racking, especially when the chair is in use. As will be described further below, the cross members 736 may also serve as a support for one or more resilient biasing devices 740 such as springs between the frame 104 and the seat assembly 108.

The side supports 732 may comprise various shapes and sizes. In general, the side supports 732 extend upward from the base of the bouncing baby chair to support the seat assembly 108 at an elevated position above the floor or ground. This allows a user to sit in the seat assembly 108 with his or her legs in a comfortable bent position. The elevation also provides space for the seat assembly 108 to bounce up and down when in use.

As shown, the side supports 732 have a trapezoidal shape, though of course other shapes may be used. For example, the side supports 732 may be rectangular, round, square, or other shapes. The side supports 732 may be an open frame, however, typically the side supports 732 will have one or more closed portions 744. For example, as shown, the side supports 732 have a closed upper portion 744 near the bottom of the seat assembly. This is beneficial in that it blocks contact with springs or other resilient biasing devices 740 connecting the seat assembly 108 to the frame 104. This prevents a user's or other person's fingers or other body parts from becoming pinched by the resilient biasing devices 740 or other moving portions of the bouncing baby chair when the chair is in use.

A lower portion of the side supports 732 may be open to save materials and thus save on costs. In addition the open portion allows a user to see underneath the seat assembly when at the sides of the bouncing baby chair. In addition, the open portion allows a user to easily access the space under the seat assembly 108 for cleaning or other purposes. Of course, the side supports 732 may be completely closed in some embodiments. In these embodiments, the space under the seat assembly 108 may be accessed from the front or back of the chair. It is noted that embodiments having a closed portion 744 may have improved rigidity over embodiments without closed portions.

In one or more embodiments, the side supports 732 may comprise a frame of a first material and a closed portion formed from a second material. For example, a side support 732 may comprise a metal frame having a wooden closed portion. Of course, a variety of combinations of materials may be used. The materials chosen may provide additional benefits. For example, a metal closed portion may be magnetic to allow users to attach one or more magnets or magnetic accessories. Also, for example, the closed portion may be formed from a less expensive material, such as plastic to save on costs. In addition, the closed portion may be removable from the frame portion such as for cleaning or replacement.

The closed portion 744 need not be rigid in all embodiments. For example, the closed portion 744 may be formed from a fabric or other flexible material. In fact, any material may be used which prevents or helps prevent a user's or other person's body parts from becoming pinched or injured by resilient biasing devices or other moving parts of the bouncing baby chair.

It is contemplated that one or more casters or wheels may be provided at the base of the bouncing baby chair. This allows the chair to be easily moved from one location to another. The wheels may have locks to hold the chair in position once the chair is at a desired location. Mobility provides an advantage in that a user may move about the house or other space while caring for a baby. For example, the user may wheel or otherwise move the chair to answer a phone call or perform other activities while the user is caring for a baby. In one or more embodiments, wheels or casters may be attached at the bottom of the side supports 732, lower cross members 736, or both.

Typically, one or more resilient biasing devices 740, such as springs or the like, will be used at a front and back portion of a seat assembly 108 to secure the seat assembly to the frame. For example, two springs may be used at the back of the seat assembly 108 and another two springs at the front of the seat assembly. The springs or other resilient biasing devices 740 may be attached at one end to the seat frame 704 (or other portion of the seat assembly 108) such as illustrated. The other end of the resilient biasing devices 740 may be attached to the frame 104. As shown in FIGS. 7A and 7D for example, springs are attached to a cross member 736 at the back of the frame 104 and to the side supports 732 at the front of the frame.

Of course, fewer or more than four resilient biasing devices 740 may be used in various embodiments of the bouncing baby chair. For example, in one embodiment, two resilient biasing devices 740 may be used to support the front of the seat assembly 108 while one resilient biasing device is used at the rear of the seat assembly. Supporting both the front and back of the seat assembly 108 allows a soothing bouncing motion to be generated by a user seated on the seat assembly. It is contemplated that only the back or front, but not both portions, of the seat assembly 108 may be supported by resilient members 740 in some embodiments. This provides a different bouncing motion similar to that described above with regard to the hinged or pivoting embodiments of the bouncing baby chair described above.

The resilient biasing devices 740 allow the seat assembly 108 to move or bounce relative to the frame 104. The resilient biasing devices 740 may be configured to stretch and then provide a force which returns the supports to their original configuration, similar to the operation of a spring or elastic member as described above. As stated, resilient biasing devices 740 may be one or more springs, elastic members, or the like. A single bouncing baby chair may utilize a variety of resilient biasing devices 740 if desired. This is advantageous in that the bouncing motion of the seat assembly 108 can be controlled in this manner. For example, stronger resilient biasing devices 740 at the back of the seat assembly 108 may reduce the amount of motion or bouncing at the rear of the seat assembly. Likewise, stronger resilient biasing devices 740 at the front of the seat assembly 108 may reduce bouncing at the front of the seat assembly.

The resilient biasing devices 740 may be attached in a variety of ways. In some embodiments, the resilient biasing devices may be attached by welds, adhesives, or fasteners. In other embodiments, supporting structures, such as hooks, clips, clamps, mounts or the like may be used. For example, as shown in FIG. 7D, resilient biasing devices 740 may be attached by one or more mounts 748. The mounts 748 provide a structure to which the resilient biasing devices 740 may be attached, and may also be sized or shaped to hold the resilient biasing devices in a particular position relative to the bouncing baby chair. For instance, the mounts 748 of the seat assembly 108 in FIG. 7D are elongated to position the resilient biasing devices 740 away from the seat assembly 108. This prevents unwanted contact between the resilient biasing devices 740 and portions of the baby chair when the chair is in use. It is noted that the resilient biasing devices 740 may be removably attached to allow for replacement in one or more embodiments. This also allows resilient biasing devices 740 to be swapped for other resilient biasing devices 740 of different strengths.

It is contemplated that resilient biasing devices 740 may be covered by a covering to prevent pinching. For example, a spring may be covered by a cylindrical, or tubular cover to prevent a user's or other person's fingers from being pinched in the spring. This is highly advantageous because the bouncing baby chair is intended for use near and with babies or small children.

In operation, a user holding an agitated baby may bounce the seat assembly 108 up and down relative to the frame 104. Because the seat assembly 108 and resilient biasing devices 740 of the bouncing baby chair support a user's body, the user does not easily become fatigued even after periods of extended use.

In general, the resilient biasing devices 740 provide resistance to the downward motion of the seat assembly 108. In addition, the resilient biasing devices 740 provide a return force which returns the seat assembly 108 upward. When the seat assembly 108 is moved downward, the resilient biasing devices 740 deform or elongate. The resilient biasing devices 740 then return to their undeformed configuration as the seat assembly 108 moves back upward. In this manner, the forces provided by the resilient biasing devices 740 help the user generate a soothing bouncing motion and reduce user fatigue.

While various embodiments of the invention have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of this invention. In addition, the various features, elements, and embodiments described herein may be claimed or combined in any combination or arrangement.
