BACKGROUND OF THE INVENTIONS1. Field of the Inventions
The present inventions relate to receptacles having doors or lids, some of the inventions relating to mechanisms configured to slow at least the closing movement of the lids.
2. Description of the Related Art
Receptacles and other devices having lids or doors are used in a variety of different settings. For example, in both residential and commercial settings, trashcans and other devices often have lids or doors for preventing the escape of the contents from the receptacle. In the context of trashcans, some trashcans include lids or doors to hide the trash within the receptacle from view. Additionally, the lid of a trashcan helps prevent contamination from escaping from the receptacle.
Recently, trashcans with rotary-type motion dampers for slowing the motion of the lids have become commercially available. More specifically, these rotary dampening mechanisms are connected to the lids of the trashcans so as to slow the closing movement of the lids. As such, the trashcan is more aesthetically pleasing because the lid closes slowly, thereby preventing a loud slamming noise when the lid is moved to a closing position.
These types of trashcans often are pedal-actuated, i.e., they include a foot pedal which is connected to the lid for moving the lid toward the open position. The rotary mechanisms are connected to the internal linkage connecting the foot pedal to the lid so as to slow the closing movement of the lid.
SUMMARY OF THE INVENTIONSAn aspect of at least one of the embodiments disclosed herein includes the realization that trash receptacles can be configured to use multiple techniques for dampening one or more movements of a lid.
Thus, in accordance with an embodiment, a trashcan can comprise a body defining an interior space, the body comprising a base portion and an upper body portion. The trashcan can further comprise a lid portion supported by the upper body portion, the lid portion comprising a lid support having an interior peripheral wall and two lids moveably mounted to the lid support so as to be independently moveable between open and closed positions, at least one of the lids having a generally concave profile. The trashcan can further comprise a first motion damper connected to the lid portion, and a second motion damper connected to the lid portion, wherein the first and second motion dampers are configured to dampen a movement of at least one of the two lids from the open position to the closed position. At least one of the two lids can comprise an exterior peripheral wall, the interior peripheral wall of the lid portion and the exterior peripheral wall of the lid being juxtaposed relative one another when the at least one lid is in the closed position so as to trap air within the lid portion and dampen lid movement when the at least one lid is moving from the open position to the closed position.
In accordance with another embodiment, a trashcan can comprise a body defining an interior space, the body comprising a base portion and an upper body portion. The trashcan can further comprise a lid portion supported by the upper body portion, the lid portion comprising at least one pivotable lid having a generally concave profile, each lid being independently moveable between open and closed positions such that the generally concave profile of the lid traps air within the interior space when the at least one lid moves from the open position to the closed position.
In accordance with another embodiment, a trashcan can comprise a body defining an interior space, the body comprising a base portion and an upper body portion. The trashcan can further comprise a lid portion supported by the upper body portion, the lid portion comprising at least one lid moveably mounted to the lid portion so as to be independently moveable between open and closed positions, the lid portion comprising an interior peripheral wall, and at least one of the lids comprising an exterior peripheral wall. The interior and exterior peripheral walls can be positioned adjacent one another when the at least one lid is in the closed position so as to trap air within the lid portion and dampen lid movement when the at least one lid is moving from the open position to the closed position.
In accordance with another embodiment, a trashcan can comprise a body defining an interior space, the body comprising a base portion and an upper body portion. The trashcan can further comprise a lid portion supported by the upper body portion, the lid portion comprising at least one lid moveably mounted to the lid portion so as to be independently moveable between open and closed positions, the lid portion further comprising an air guide configured to guide air downwardly into the interior space as the at least one lid moves from the open position towards the closed position.
The above mentioned and other features of the inventions disclosed herein are described below with reference to the drawings of preferred embodiments. The illustrated embodiments are intended to illustrate, but not to limit the inventions. The drawings contain the following figures:
The embodiments of a receptacle with at least one lid are all disclosed in the context of a trashcan. The inventions disclosed herein are described in the context of a trashcan because they have particular utility in this context. However, the inventions disclosed herein can be used in other contexts as well, including, for example, but without limitation, large commercial trashcans, doors, windows, security gates, and other larger doors or lids, as well as doors or lids for smaller devices, such as high precision scales, computer drives, etc.
In the illustrated embodiment, the base portion 26 can be configured to support the assembly 20 in a stable resting position when the assembly 20 rests on a surface such as a floor, which may be smooth, or uneven. The base portion 26 can be configured to support the upper body portion 28 such that the upper body portion 28 can extend upwardly from the base portion 26.
The upper body portion 28 can include at least one container 30 which can be also be referred to as a “bin” or “liner”. The at least one container 30 can be configured to define an interior cavity or cavities. In some embodiments, such as illustrated in
In some embodiments, the containers 30 can be formed from sheet metals, such as sheet stainless steel, or other metals, or other materials including plastics, etc. In some embodiments, when sheet metal is used, such as sheet stainless steel, the containers 30 can be made from any of 23-26 gauge stainless sheet steel. Of course, the thinner the gauge sheet steel, the lighter and less expensive the containers 30 will be.
The lid portion 24 can comprise a lid support member 32 extending generally around the periphery of the lid portion 24. The lid support member 32 can provide support for and be attached to at least one moveable lid 34.
The lid portion 24 illustrated in
The moveable lids 34 can be moveably mounted to the lid portion 24 with any known device, such as a hinge which can allow pivoting motion of the moveable lid 34, or other devices providing different movements. The connection between the lid or moveable lids 34 and the lid portion 24 can be constructed, for example, so as to connect the moveable lids 34 to the lid support member 32 or, in some embodiments, directly to the shell or shells 30.
The lid portion 24 can further comprise a handle or handles 36. The handles 36 can be located generally along a front portion of the receptacle assembly 20, such as illustrated in

In some embodiments, the assembly 20 can include at least two dampers 38 arranged on opposing sides of the lid support 24 so as to provide independent dampening against the movement of each of the moveable lids 34. The description of the damper 38 set forth below applies to both of the dampers 38, although only one damper 38 and its components are specifically identified below.
With reference to
In some embodiments, the damper 38 can be configured to dampen the downward movement of a moveable lid 34. As used herein, the “downward movement” of the moveable lid 34 corresponds generally to the movement from a position of the moveable lid 34 as viewed in
With reference to
The dampening function of the damper 38 can be achieved by way of the resistance of the flow of a fluid, such as air, into and out of the housing 56. Additionally, or alternatively, the dampening function of the damper 38 can be achieved by way of the resistance of a biasing element inside the housing 56. This resistance of flow and/or biasing can generate sufficient damping forces for slowing the closing of the moveable lid 34. Such forces can be large.
With continued reference to
The damper 38 can optionally further comprise a biasing element 60. The biasing element 60 can comprise a spring, elastic membrane, or other type of biasing device. As illustrated in
The biasing element 60 can also be connected with and/or in contact with a piston support 62. The piston support 62 can comprise an element configured to slide within the housing 56, and can include a groove, recess, or other area for receiving a seal 64.
With continued reference to
The piston guide 68 can extend through a receiving area 70 on the lid support 24. The receiving area 70 can include an aperture 72. One end of the piston 66 can thus extend through both the piston guide 68 and aperture 72.
With continued reference to
The seal 64 can be generally annular in shape, having an inner wall 74 and an outer wall 76 connected by a top wall 78. The outer wall 76 can include an upper portion 80 that extends generally parallel to an inner wall of the housing 56, and a projecting portion 82 that is biased to extend radially outwardly relative to the upper portion 80. As such, the outer diameter of the seal 64 defined by the upper portion 80 is slightly smaller than the outer diameter of the seal 64 defined by the projecting portion 82. Additionally, the ramped configuration of the projecting portion 82 (when in a relaxed state) relative to the upper portion 80 helps to achieve the check valve type functionality of the seal 64.
With continued reference to
In some embodiments, as the piston engaging mechanism 84 pushes the piston 66 down into the housing 56, the relative pressure between the atmosphere acting on the bottom of the piston support 62, and the air trapped between the top of the piston support 62 and the top of the housing 56 can oppose the immediate downward motion of the piston 66 as the piston 66 begins to move downwardly, and thus oppose the downward motion of the moveable lid 34.
In some embodiments, the damper 38 can be configured to provide less resistance to the upward movement of the piston 66 within the housing 56 but provide greater resistance against the downward movement of the piston 66 within the housing 56. This can be accomplished in any known manner.
For example, with continued reference to
However, when the piston 66 and piston support 62 move downwardly within the housing 56, the air pressure in the space above the piston support 62 drops relative to the pressure of the atmosphere, thereby causing the projecting portion 82 to further expand against the inner walls of the housing 56. This generates additional resistance to the flow of air into the space above the piston support 62. As such, the seal 64 generates more resistance to the downward movement of the piston 66 than against the upward movement of the piston 66.
In some embodiments, the seal 64 can be lubricated with graphite powder. Such lubrication with graphite powder and the construction of dampers, which can be applied to the present dampers 38, are disclosed in U.S. Pat. Nos. 6,513,811 and 6,726,219, the entire contents of both of which, including the specific portions including the descriptions of damper design and lubrication with graphite powder, are hereby incorporated by reference. Additionally, the size of the damper 38 can be chosen by the designer to provide the desired functionality and performance.
For example, the height of the housing 56, which can determine the length of the maximum vertical movement of the piston 66 within the housing 56, can be chosen to accommodate the maximum desired vertical displacement of the piston support 62 within the housing 56. Additionally, the diameter of the housing 56 and the type of seal 64 used can affect the resistance generated during the downward movement of the piston 66. Thus, these dimensions can be chosen to provide the desired dampening characteristics.
Further advantages can also be achieved where the size of the housing 56 and the position at which the housing 56 is mounted within the assembly 20 can be adjusted to provide desired characteristics of the motion of the moveable lid 34 during its closing movement. For example, if the housing 56 is mounted in a position where the piston support 62 is spaced excessively far from the top of the housing 56 when the piston 66 is at its maximum vertical position, the moveable lid 34 can initially move too quickly from its fully opened position toward its closed position. Such an initial quick movement can cause the moveable lid 34 to bounce during its downward movement.
However, if the mounting position of the housing 56 is adjusted, or the damper 38 in general is adjusted, so that the piston support 62 is closely spaced relative to the top of the housing 56 when the piston 66 is at its maximum upper position, the damper 38 can provide additional dampening, at least initially, thereby providing a slower, more aesthetically pleasing motion.
For example, by adjusting the position of the housing 56 and/or configuration of the damper 38 to space the piston support 62 near the top of the housing 56 when the piston 66 is at its maximum position, the moveable lid 34 can begin to move very slowly initially, and slowly accelerate to an acceptably slow closing speed, such that the moveable lid 34 does not make an excessive loud noise when it finally comes to rest. In some embodiments, the spacing can be equal to or less than about 10% of the total movement of the piston 66. The initial movement of the piston 66 can be further slowed at a spacing of about 5% or less of the total movement of the piston 66. Finally, mounting the housing 56 and/or adjusting the damper 38 such that the spacing is about 4% or less of the total movement of the piston 66 can provide further slowing, and thus achieve a more aesthetically pleasing movement.
A designer can choose the appropriate housing, piston, and seal combination to achieve the desired closing speed. Thus, in some embodiments, at least one of the moveable lid 34, housing 56, piston 66, piston support 62, and seal 64 can be configured to achieve the desired closing speed. In some embodiments, for example, but without limitation, the above parameters can be chosen to achieve a closing speed of the lid of about 5 seconds from the moment the center of gravity of a moveable lid 34 passes over a pivot point and gravity begins to pull the moveable lid 34 closed.
With continued reference to
With continued reference to
When the moveable lid 34 is moved down towards a closed positions (e.g. when gravity is pulling the moveable lid 34 down), the surface 86 of the piston engaging mechanism 84 can contact the top of the piston 66 and drive the piston 66 down through the piston guide 68 and further into the housing 56. As the piston 66, and piston support 62, are moved further into the housing 56, the biasing element 60 can resist the motion of the piston support 62, such that the speed of the moveable lid 34 as it is closing is reduced prior to the moveable lid 34 reaching a fully closed position. In some embodiments, the fully closed position can be considered the position achieved when the moveable lid 34 contacts a portion of the lid support member 32. In some embodiments, the fully closed position can correspond to when the moveable lid 34 is substantially closed, but not contacting the lid support member 32.
With continued reference to
The assembly 20 can comprise additional or alternative damping mechanisms apart from the damper 38 described above. For example, the lid portion 24 can be configured to utilize the air flow generated during a closing movement of a lid 34 to further dampen the closing movement.
For example, in some embodiments, at least one of the moveable lids 34 can have a concave configuration and profile, as illustrated for example in
Additionally or alternatively, and with reference to
The lid support member 32 can include an internal peripheral wall 96 adjacent the top edge 92, the internal peripheral wall 96 extending around at least a portion of the periphery of the lid support member 32. The internal peripheral wall 96 can have a shape or configuration complementary to that of the peripheral wall 94. In some embodiments, the peripheral wall 96 can include cutouts, notches, or gaps if desired. As described above, the lid support member 32 can further include a lower wall 88. The lower wall 88 and peripheral wall 96 together can form a shoulder, with the peripheral wall 94 sitting or nesting within the shoulder when the moveable lid 34 is in a closed position.
In some embodiments, the fit and/or tight spacing between the peripheral wall 94 and the shoulder defined by walls 88 and 96 can form a generally air resistant seal between the lid support member 32 and moveable lid 34. However, it is not necessary for the above-described fit to form an air resistant seal. The contact and or close spacing between the peripheral walls 94 and 96 can be sufficiently continuous to resist the flow of air therebetween to achieve the desired dampening effect.
For example, as the moveable lid 34 moves from an open position to a closed position, the peripheral wall 94 of the moveable lid 34 can move into close proximity to the wall 96 of the lid support member 32, and a slight compression of the air within the containers 30 and/or body portion 22 can be generated. When the moveable lid 34 is in its open position, the air within the body portion 22, existing within and above any trash that may be contained in the containers 30 or liners inside the containers 30, is at atmospheric pressure.
As the moveable lid 34 closes, a positive pressure can be created in the assembly 20, and air underneath the moveable lid 34, including but not limited to air near the wall 88 and air within the body portion 22, is urged out of the assembly 20 in order for the moveable lid 34 to close completely. However, because of the tight fit between the peripheral wall 94 and the peripheral wall 96, some or all of the air can be retained, briefly retained, or temporarily trapped, thus providing at least some air resistance to downward movement of the moveable lid 34. As gravity, or any other force, continues to push the moveable lid 34 toward a closed position, this “trapped” air can leak out through the small space between the peripheral wall 94 and peripheral wall 96, or through other apertures or openings in the assembly 20. The configuration of the peripheral walls 94 and 96 can thus act as an air guide, guiding the trapped air slowly out of the assembly while dampening the movement of the moveable lid 34.
The clearance between the walls 94 and 96 can be altered. For example, the configuration and/or size of the walls 94 and 96 can vary, such that the amount of time the walls spend moving past one another, or in close proximity to one another, can change. In some embodiments, an increased height of one or both walls can increase the time the moveable lid 34 is dampened, thus slowing down the movement of the moveable lid 34 to an even greater degree, or for a greater amount of time. Changing the shape of the walls 94 and 96, or introducing other components or elements along the periphery of the moveable lid 34 and/or lid support member 32, can further alter the dampening effect.
By providing additional dampening, in additional to the dampening provided by the damper 38, can provide further advantages. For example, because the air “trapping” technique noted above, begins to act just as the lid nears the fully closed position. This is also the point at which the torque created by the weight of the lids 34, pivoting the lids 34 toward their closed position, is the greatest. This is because as the lids 34 move from their fully opened position toward their open position, the centers of gravity of the lids 34 move from points nearly directly above the associated hinges, outwardly. As the lids 34 reach a horizontal position, their respective centers of gravity are at their maximum horizontal spacing from the axes of the hinges. As such, the greatest torques generated by the weights of the lids 34 are generated as the lids 34 reach their fully closed positions. Thus, by providing additional dampening as the lid nears its fully closed position helps compensate for this additional torque. Further, modifying the dampers 38 to provide quickly increasing damping forces can be difficult.
With reference to
The assembly 120 can comprise a lid portion 24, an upper body portion 128, and a base portion 126. The lid portion 24 can comprise a lid support member 32, moveable lids 34, and handles 36, as described above. In some embodiments, the lid portion 24 can rest on or be supported by the upper body portion 128.
The upper body portion 128 can comprise a single outer shell 31, which can receive the containers 30 as illustrated in
With reference to
With reference to
With reference to
The upper support member, such as for example lid support member 32, can be configured to support a container 30 within the interior cavity or cavities defined by the shell or shells 31. In some embodiments, the upper support member can include a shoulder configured to support an outwardly extending lip 102 of the container 30. As such, the liner or containers 30 can hang within the shell or shells 31 from the upper support member. However, in other configurations, the liner or containers 30 can rest upon an interior surface of the upper body portion 28, 128, lid portion 24, or the base 26, 126. In such a configuration, the upper support member, while it does not support the weight of the liner or containers 30, can provide for alignment of the liner or containers 30 within the body of the assembly 20. In some embodiments, the container or containers 30 can further comprise a bag retainer 104. The bag retainer 104 can be used to securely hold a plastic, or other type material, bag within the container 30. In some embodiments, the bag retainer 104 can comprise an elongate slot with a plurality of fingers nested together in a side-by-side relationship. In other embodiments, the bag retainer 104 can comprise openings, such as a circle or oval.
With reference to
As with the embodiment illustrated in
Additionally, the lid support member 32 can comprise a top edge 92. The lid support member 32 can include an internal peripheral wall 96 adjacent the top edge 92, the internal peripheral wall 96 extending around at least a portion of the entire periphery of the lid support member 32. The internal peripheral wall 96 can have a shape or configuration complementary to that of a peripheral wall 94 (not shown) on the moveable lid 34. The lid support member 32 can further include a lower wall 88. As described above, the lower wall 88 and peripheral wall 96 can together form a shoulder, with the peripheral wall 94 of the moveable lid 34 sitting or resting tightly within the shoulder when the moveable lid 34 is in a closed position.
As described above, the fit and/or tight spacing between the peripheral wall 94 of the moveable lid 34 and the shoulder defined by walls 88 and 96 can form a generally air resistant seal between the lid support member 32 and moveable lid 34. However, it is not necessary for the above-described fit to form an air resistant seal. The contact and or close spacing between the peripheral walls 94 and 96 can be sufficiently continuous to sufficiently resist the flow of air therebetween to achieve the desired dampening effect.
With reference to
In some embodiments, the moveable lid or lids 34 can be moved by use of a pedal actuating mechanism or mechanisms. For example, the receptacle assembly 20 or 120 can include one or more pedal actuating mechanisms as described in U.S. Patent Publication No. 2006/0196874, U.S. Pat. No. 7,656,109, U.S. Patent Publication No. 2007/0182551, U.S. patent application Ser.
