The invention relates to a reciprocating platform for holding infant carriers, and more specifically relates to a reciprocating platform that is expandable to accommodate different sized carriers.
BACKGROUNDIt has long been known that oscillatory motion can induce a small child, especially an infant, to sleep. Rocking has been a method used by caretakers for thousands of years to help infants fall and remain asleep. It is also well known that the movements involved with transporting an infant can help induce it to sleep. For example, the motion associated with pushing a stroller or riding in a car frequently put infants to sleep. Devices have been developed to simulate this motion mechanically. For example, electrically powered rockers which automatically swing an infant back and forth in a consistent rhythm have been developed.
None of the methods are guaranteed to induce a child to sleep. However, once asleep, some infants will awaken once the movement is stopped. Also, the process of moving an infant from a stroller or car seat to an automatic rocker can rouse an infant. Once the child is awake, it may not return to sleep. Accordingly, there are devices which can convey motion to an infant carrier, such as a stroller or car seat, once the infant is no longer traveling.
For example, International Patent Application Serial No. PCT/GB/00474 discloses a device with a platform that moves back and forth while pivoting to replicate rocking. The device includes a box next to the platform that houses a motor to impart the motion to the platform. The overall design of the device is large and awkward and is intended to be stationary.
The BabySitter by Robopax is somewhat smaller and includes an actuator under the platform. However, the platform is not expandable, and the device must be as large as the platform. This can be cumbersome if the device is designed to accommodate a large stroller.
Accordingly there is a desire for a device which can accommodate an infant carrier and has an expandable platform such that it can be made small and portable. There is also a desire for such a device to accommodate both large carriers, such as strollers, and smaller carriers, such as car seats. Further, the device may be portable, so the caregiver can transport it easily to another location or destination outside the care giver's home.
SUMMARY OF THE INVENTIONThe invention provides a reciprocating device for holding an infant carrier that is expandable to accommodate carriers of various sizes. The device includes a base member that is stationary with respect to a support surface and a platform that reciprocates above the base member. The reciprocation is executed by an actuator. The reciprocation of the platform on the base member may be linear. Accordingly, the actuator can be a linear actuator, or a rotating motor with linkage to convert the rotating motion to a linear motion.
The device may include one or more features which allow it to expand in either length, width or both. The platform can include expansion trays which may extend outward, increasing the usable surface area of the platform. The expansion trays are movable between a first contracted position, where the platform is small and a second expanded position. The expansion trays may slide relative to the rest of the platform.
Alternatively, the platform may be foldable, such that it can be folded and smaller or open and larger. The device may include various elements to support the unfolded section of the platform when the platform is open. For example, the base member can be expandable, a second base member may be included, or the platform can have its own support members, such as wheels.
To accommodate a wide range of different sized baby carriers, the device may include more than one expansion feature. The device can be both foldable and include an expansion tray. The expansion trays can be used when the device is in the unfolded position. In the expanded position, the device is open (unfolded) and the expansion trays are in an extended position. Each side of the folded platform is supported by a base member.
The expansion trays can be slidably connected to the rest of the platform. To keep the expansion trays in a desired position they can be temporarily fixed in place. For example, the connection between the expansion tray and the platform can include spring-loaded locks, such that the trays can lock in both an extended and a contracted position.
The platform is also slidably connected to the base members, with each half of the foldable platform connected to a different base member. For instance, a first section of the platform can be slidably connected to a first base member and a second section of the platform can be slidably connected to a second base member. Rollers can be included between the platform and base members, such that the reciprocation of the platform is smooth.
The platform, including an expansion tray, can be foldable about a hinge or pivot joints. To fold the device, the second section of the platform is rotated about the hinge such that it rests above the first section of the platform. The hinge is not limited to a specific embodiment and only defines the part of the platform through which the two sections are foldably connected. The hinge can be formed integrally with one of or both of the platform sections, or can be separate parts attached to the sections of the platform. Consequently, the second base member, which is attached to the second section of the platform, is also rotated about the pivot joint. Thus, when the device is in the folded position the second base member is above the platform and forms the support surface for a baby carrier. Accordingly, the second base member may be designed to have a surface which acts as the bottom when in the open position, but acts as the carrier surface when in the folded position.
In the folded position the device is smaller and can be portable. Accordingly, the device can include a handle or strap for added convenience to the user.
These and other objects and features of the invention will become more apparent by referring to the drawings, in which:
Platform 40 may be in the form of a flat surface which supports the child carrier. In order to change the size of the platform surface, platform 40 may include one or more expansion trays 66. The expansion trays 66 have a retracted position fitting tightly into the platform 40, such that the platform 40 is in a compact position. In the compact position, platform 40 is more easily transported and takes up less space. Each expansion tray 66 also has an extracted position increasing the surface of platform 40. Expansion tray 66 may slide away from the rest of the platform 40 into an extracted position to form an expanded position of platform 40. In the illustrated embodiment part of the main body of the platform is exposed between the expansion trays. However, the expansion trays 66 can each be half the width of the platform, such that they touch when in the compact position. In the compact position, the expansion tray 66 may be held under, above, or within the rest of the platform 40. The expansion tray 66 may be movable in an up and down direction once in the extracted position to align with the top of the platform. For example, if expansion tray 66 is held beneath the rest of the platform 40 in the compact position, it may be raised when placed in the extracted position to be flush with the top of the platform 40. In
Other methods can also be used to support second section 46. For example, as shown in
Another embodiment, shown in
The device 1 may be portable so that the care giver of the child can take the device to locations outside of the care giver's home. The expandability of the platform 40 surface allows the device to be small such that it is easy to carry. Further, the device 1 can include a handle (see
The device 1 may include additional features to aid in calming the infant. For example, device 1 can include a system for playing music. Device 1 can include speakers for playing music to soothe the infant. Pre-recorded music can be stored in a memory within device 1 to be played over the speakers. Additionally, device 1 may include a radio receiver to receive AM, FM or satellite music broadcasts. Similarly, device 1 may include a receiver for other wireless signals, such as Wi-Fi. Further the device may include a signal port to receive audio signals from an external device. For example, device 1 may include an electrical cable to connect to the headphone port of an audio device, such as a portable audio player or computer. Alternatively, device 1 can include a docking station for a portable music player, such as an MP3 player.
The oscillation of device 1 can be linear, such that the platform oscillates back and forth. The speed of the motion may be uniform back and forth or it can be sinusoidal such that the platform moves faster through the middle of its path. Alternatively, the platform can oscillate in a non-linear manner, for instance the platform may translate in a circle or other shape. Further, the platform can twist or rock as it moves. The motion can be made to replicate the motion of a car or rocking in a care giver's arms. Device 1 may include controls for changing the motion of the platform. The controls can change the overall speed of the motion, or change the path of the motion. Further, device 1 may be configured to oscillate according to the rhythm of music being played through the speakers, if provided.
The details of a specific embodiment of the invention which has a platform 40 that includes both expansion trays 66 as well as first and second sections 44, 46 is shown in
The expansion trays 66 may be fixedly attached to the rest of platform 40 in such a way that they are slidable between a retracted position and an extracted position. As shown in
Of course, the location of the peg 68 and slot 58 may be rearranged, such that the peg 68 is part of the main body of the platform 40 and the slot 58 part of expansion tray 66. Likewise, other mechanisms and designs may be used to fix the expansion tray 66 onto the platform 40 while allowing it to slide. The shown and described peg and slot embodiment is exemplary. If the user does not require such a large platform, the expansion trays 66 may be placed and held in the retracted position, as described below.
The connection used for fixing the platform 40 onto base member 10 may be similar to that used to attach expansion tray 66 onto platform 40, as shown in
For added stability, each base member 10 may include a bar 24 that runs its length and fits within a complimentary trench 54 in the platform 40, illustrated in
Rollers 20 may be included on either the platform 40 or base member 10 to reduce friction between these parts as the platform 40 is oscillated. In the illustrated embodiment a plurality of rollers 20 are attached to each base member 10. Smooth flat surfaces are included on the platform sections 44, 46 as rolling paths 50 corresponding to rollers 20. Each roller 20 may be recessed in a cavity 21 exposing only a small rolling surface above the surface of the base member 10, depicted in
As stated above, actuator 70 is held in a housing 72 that is fixed to platform 40. The housing 72 may be larger than the actuator, as shown in
In the illustrated embodiment, actuator 70 is a motor that is fixed within housing 72 relative to platform 40. As platform 40 oscillates so can motor 70. Motor 70 is coupled to a drive arm 80 that interacts with one of the base members 10 to drive platform 40 in an oscillatory motion. The base member 10 which interacts with drive arm 80 is described as the first base member 14, while the other is described as the second base member 16. The drive arm 80 is positioned below platform 40 and is coupled to motor 70 through a hole in the platform. Drive arm 80 is attached at a first end 86 to a shaft 84 that is driven by motor 70. As motor 70 turns, drive arm 80 rotates about the end 86 which is attached to the shaft 84.
The operation of the actuator is illustrated in
Extension 82 may include a drive wheel 83 which rides against the sidewall 78 of well 76. Drive wheel 83 reduces friction between extension 82 and well 76. Thus, a smooth, even motion is imparted in platform 40 as drive arm 80 rotates. In a preferred embodiment, platform 40 oscillates with respect to both first base member 14 and second base member 16. However, actuator 70 and drive arm 80 act only on the platform 40 and first base member 14. Thus, platform 40 does not inherently oscillate relative to second base member 16. Therefore, a temporary attachment member 98 may be included to secure second base member 16 to first base member 14 when device 1 is in an open position. Accordingly, platform 40 oscillates with respect to both base members 10. The temporary attachment member 98 may be one or more magnets linking the base members 10.
The platform first section 44 and second section 46 may be held together by pivot joints 102 which act as a hinge 100. To place device 1 in the folded section, shown in
In the folded position, device 1 is smaller and more portable. A handle 96 may be included on device 1 for easier carrying. The handle 96 preferably extends to the side of device 1 such that it is in a vertical orientation when being carried by handle 96. The side of device 1 opposite handle 96 may include a floor pad (not shown) to secure device 1 when set down temporarily during transport. As shown in
Although the preferred form of the invention has been shown and described, many features may be varied, as will readily be apparent to those skilled in this art. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
