Description
COLLAPSIBLE BAG HOLDER
Field of Invention This invention relates to containers. In particular, this invention relates to a collapsible bag holder for supporting a bag, for example for use as a trash container.
Background of the Invention Organization is important to the efficient use of a workspace in the home, such as a workshop or kitchen, laundry room, garage and the like, and commercial, industrial or institutional workspace such as hospitals, manufacturing facilities etc.
Particularly in a small workspace, such as a garage or basement workshop, it is advantageous to maintain as much free space as possible for working with tools and materials. One of the ways to maintain an organized workshop environment is through the efficient disposal and storage of trash and refuse.
Because trash bags are not self supporting, trash and refuse is typically discarded in a rigid-walled refuse container such as a trash can, which provides a supporting structure for the temporary storage of trash and refuse. Often the trash can is lined with a bag, to facilitate transfer of trash to a disposal location for garbage pickup. Typically the lip about the bag opening is folded over the rim of the container to hold the bag open for easy use. But since the bag is rarely the same shape as the container, and thus is unlikely to line the interior wall of the container closely, as the bag is filled it tends to be pulled into the container by the weight of the trash and drawn off of the rim of the container, which makes it awkward to continue filling the bag.
If the refuse container is not lined with a bag, the trash must be transferred from the trash can to a bag for disposal, so the container must be invertible. This renders it impractical to mount the container, which can thus occupy considerable floor space. In a small workspace this can be inconvenient and an inefficient use of space.
Another disadvantage of using a rigid-walled refuse container, particularly in a small workspace, is that the container occupies the same volume of space whether the container is full, partially filled or completely empty. The container can thus unnecessarily occupy a relatively large portion of the workspace even when it is empty or only partially filled.
Still a further disadvantage to using a rigid-walled trash container is that a separate component such as a lid is required to close the container when not in use.
This is particularly disadvantageous in the case of decomposable trash such as food and other organic matter, which is often encountered in a workspace such as a kitchen. The need for a separate lid in these situations is inconvenient and renders the container more expensive to manufacture.
Summar~of the Invention The present invention overcomes these disadvantages by providing a collapsible bag holder for supporting a free-hanging bag. The bag holder according to the invention is mounted in any convenient location, to support the bag with the bag opening retained in a open condition for disposal of trash, and can be collapsed to support the bag with the bag opening retained in a closed, substantially sealed condition in which the space occupied by the trash bag is only as large as the volume of trash contained within the bag.
The invention accomplishes this by providing a frame comprising a stationary rear frame member, a movable front frame member movable between open and closed positions, and opposed folding side frame members which can be collapsed to move the front frame member to the closed position and extended to move the front frame member to the open position.
The frame may be mounted to the supporting structure by any suitable means. In a preferred embodiment the collapsible bag holder is mounted to a bracket affixed to the supporting structure, which provides clips that detachably lock under the front frame member to releasably retain the frame in a collapsed position. In a further embodiment the frame may be composed of a magnetic material such as steel, and a magnet retains the frame in the closed position.
In the preferred embodiment the rear frame member comprises a flange which underlies the front frame member when the frame is in the closed position, and a resilient strip extending along the flange which compressibly engages against the bag wall when the frame is in the closed position, substantially sealing the bag.
The holder of the invention preferably includes retaining strips for retaining the bag wall on the frame, each comprising a resilient channel which compressibly engages the bag wall against the respective front and rear frame members.

Summar~of the Invention The present invention overcomes these disadvantages by providing a collapsible bag holder for supporting a free-hanging bag. The bag holder according to the invention is mounted in any convenient location, to support the bag with the bag opening retained in a open condition for disposal of trash, and can be collapsed to support the bag with the bag opening retained in a closed, substantially sealed condition in which the space occupied by the trash bag is only as large as the volume of trash contained within the bag.
The invention accomplishes this by providing a frame comprising a stationary rear frame member, a movable front frame member movable between open and closed positions, and opposed folding side frame members which can be collapsed to move the front frame member to the closed position and extended to move the front frame member to the open position.
The frame may be mounted to the supporting structure by any suitable means. In a preferred embodiment the collapsible bag holder is mounted to a bracket affixed to the supporting structure, which provides clips that detachably lock under the front frame member to releasably retain the frame in a collapsed position. In a further embodiment the frame may be composed of a magnetic material such as steel, and a magnet retains the frame in the closed position.
In the preferred embodiment the rear frame member comprises a flange which underlies the front frame member when the frame is in the closed position, and a resilient strip extending along the flange which compressibly engages against the bag wall when the frame is in the closed position, substantially sealing the bag.
The holder of the invention preferably includes retaining strips for retaining the bag wall on the frame, each comprising a resilient channel which compressibly engages the bag wall against the respective front and rear frame members.
The present invention thus provides a collapsible holder for mounting to a supporting structure, for supporting a flexible bag having a flexible bag wall and a top opening, the holder comprising a frame comprising: a stationary rear frame member, a movable front frame member, movable between an open position spaced from the rear frame member to retain the top opening in an open condition, and a closed position substantially abutting the rear frame member to retain the top opening in a closed condition, and opposed folding side frame members, each side frame member having an intermediate hinge and hingedly affixed to ends of the front and rear frame members, wherein when the holder is mounted to a supporting structure and the top opening of a bag is affixed to the frame, the side frame members can be collapsed to move the front frame member to the closed position and can be extended to move the front frame member to the open position.
The present invention further provides, in combination, a flexible bag having a flexible bag wall and a top opening, and a collapsible holder for mounting to a supporting structure, the holder comprising a frame comprising: a stationary rear frame member, a movable front frame member, movable between an open position spaced from the rear frame member to retain the top opening in an open condition, and a closed position substantially abutting the rear frame member to retain the top opening in a closed condition, and opposed folding side frame members, each side frame member having an intermediate hinge and hingedly affixed to ends of the front and rear frame members, wherein when the holder is mounted to a supporting structure and the top opening of a bag is affixed to the frame, the side frame members can be collapsed to move the front frame member to the closed position and can be extended to move the front frame member to the open position.
In further aspects of the invention, the frame is mounted to a bracket affixed to the supporting structure, the bracket providing clips which detachably lock under the front frame member to releasably retain the frame in a collapsed position; the frame is composed of metal; one of the front frame member or the rear frame member comprises a flange which underlies the other of the front frame member or the rear frame member when the frame is in the closed position; the flange is provided along the rear fr~~rne member and the flange or a bottom portion of the front frame member, or both, is provided with a resilient strip which compressibly engages against the bag wall when the frame is in the closed position; the intermediate hinges are disposed generally centrally along the side frame members; the holder further comprises retaining strips for retaining the bag wall on the frame, which may extend along top edges of the front and rear frame members and may comprise resilient channels which compressibly engage the bag wall against the frame members; and/or the frame is removably mounted to a bracket by opposed slots in the bracket spaced from the supporting structure and adapted to receive the rear frame member.
Brief Description of the Drawings In drawings which illustrate by way of example only a preferred embodiment of the invention, Figure 1 is a perspective view showing the invention supporting a bag in the open condition, Figure 2 is a perspective view showing the frame of Figure 1 in a partially closed condition, Figure 3 is a perspective view showing the frame of Figure 1 in a fully closed condition, Figure 4 is an enlarged perspective view of the closing mechanism in Figure 2, Figure S is a top plan view showing the frame of Figure 1 in the open position, and Figure 6 is a perspective view of a further embodiment of the invention supporting a bag in the open condition.
Detailed Description of the Invention Figure 1 illustrates a preferred embodiment of the collapsible holder 10 of the invention, mounted to a supporting structure 2, such as a wall, table top, pegboard etc., and supporting a trash bag 4 (shown in phantom lines) having a flexible bag wall 6 and a top opening 8. The holder 10 comprises a frame 12 comprising a stationary rear frame member 20, a movable front frame member 30 and opposed folding side frame members 40.
In the preferred embodiment the frame 12 is composed of steel, however the frame 20 may be composed of any other suitably rigid material including other metals such as aluminum, plastic, wood, or any combination thereof.
The frame 12 may be provided with any suitable mounting means for mounting the holder 10 to a supporting structure 2. In the embodiment shown mounting means comprises a bracket 32 from which projects generally forwardly clips 34 which removably receive the rear frame member 20, as described below. This provides the advantage that the frame 12 is readily removable for cleaning or relocation; however the frame 12 may be mounted in any other suitable fashion.
Each side frame member 40 has an intermediate hinge 42 which allows the side frame members 40 to fold at an intermediate point, preferably generally centrally.
The side frame members 40 are also hingedly affixed to the ends of the rear and front frame members 20, 30 at hinges 44, 46, respectively. This allows the side frame members 40 to collapse, preferably inwardly to conserve space, so that the front frame member 30 is movable between an open position spaced from the rear frame member 20 to retain the top opening in an open condition, as shown in Figure 1, and a closed position substantially abutting the rear frame member 20, as shown in Figure 3, to retain the top opening 8 of the bag 4 in a closed condition. The side frame members 40 are preferably restricted from extending to 180 degrees, to ensure that they collapse inwardly merely by movement of the front frame member 30. The front frame member 30 may optionally be provided with a handle 38 to facilitate opening and closing the holder 10.
According to the preferred embodiment the clips 34, best seen in Figure 4, each project generally forwardly from an end of the mounting bracket 32 and provide a slot 34a into which a portion 20a of the rear member 20 is slidably disposed, to mount the frame 12 to the bracket 32. In the preferred embodiment the clips 34 further provide a ledge 34b having a top edge with a depression 34c in which a portion 30a of the front frame member 30 rests when the frame 12 is in the closed condition, as shown in Figure 3, to thus retain the frame 12 in the closed condition under the weight of the bag 4 and its contents.
In a further embodiment one of the front frame member 30 or the rear frame member 20 may be provided with a magnet 22 affixed by epoxy or any other suitable means. In this embodiment the frame 12 preferably is composed of or comprises a magnetic material, so that when the holder 10 is moved to the closed position shown in Figure 3, magnetic attraction between the magnet 22 and the rear or front frame member 20 or 30 retains the frame 12 in the closed position. If the frame 12 is not composed of a magnetic metal, a separate piece of magnetic material can be affixed to the frame 12 opposite the magnet to allow the frame 12 to be magnetically retained in the closed position. Other means may be used to retain the holder in the closed position.
The invention also provides means for sealing the bag 4 when the holder 10 is in the closed position. In the embodiment of Figure 6, the bottom edge of the rear frame member 20 comprises a flange 24, which is preferably formed integrally with the rear frame member 20 and underlies the front frame member 30 when the frame 12 is in the closed position. Thus, in the closed condition the bag wall 6 passes between the lower edge of the front frame member 30 and the upper surface of the flange 24.
In the preferred embodiment the flange 24 is provided with a resilient strip 26, for example a compressive urethane foam strip such as is used as weather stripping, extending along the flange 24, preferably along substantially its entire length. The strip 26 compressibly engages against the bag wall 6 when the frame 12 is in the closed position to substantially seal the bag 4 and thus retain unpleasant odors within the bag 4. This can be advantageous in the case of decomposable refuse, such as organic matter, or chemical refuse such as rags or paper litter used for cleaning oil-based solvents or the like. It will be appreciated that the resilient strip 26 could instead be disposed along a bottom portion of the front frame member 30, or resilient strips 26 could be disposed along both the flange 24 and the front frame member 30 to seal the bag 4 in a similar fashion. It is also possible to position the flange 24 so that there is a tight fit between the flange 24 and the bottom edge of the front frame member 30, or to provide a bead or recess which the bottom edge of the front frame member 30 abuts in the closed position, but these rigid sealing structures are not preferred because repeated closing and opening of the holder 10 could tear the bag wall 6.
The flange 24 may alternatively be provided along the lower edge of the front frame member 30, to underlie the rear frame member 20 when the frame 12 is in the closed position, although this is not preferred as it may require that the frame 12 be spaced too far from the supporting structure 2 in order to accommodate the flange 24 as the frame 12 is collapsed to the closed position.
The invention may include means for securing the bag 4 to the holder 10. In the preferred embodiment retaining strips 50, 52 are provided for retaining the bag 4 on the frame 12. Preferably the retaining strips 50, 52, comprising resilient channels, extend along the top edges of the rear and front frame members 20, 30, respectively, to compressibly engage the bag wall 6 against the frame members 20, 30. The rear retaining strip 50 may optionally have a backstop flap SOa covering any space between the rear frame member 20 and the supporting structure 2, as shown in Figure 1, and the front retaining strip 52 may optionally have a cover flap 52a covering the space between the front frame member 30 and the rear frame member 20 when the frame 12 is closed, as shown in Figure 3.
In use, the holder 10 is mounted to a supporting structure 2 by fastening mounting bracket 32 to any convenient support structure 2 such as a wall, worktable etc., as by screws or any other suitable fastener, and engaging the extension portions 20a of the rear frame member 20 into the slots 34a. With the frame 12 in the open position shown in Figure 1, the bag 4 is affixed to the frame 12 by inserting the bag 4 through the frame 12, folding the bag wall 6 about the top opening 8 over the rear and front frame members 20, 30, and slip-fitting the retaining strips 50, 52 over the top edges of the rear and front frame members 20, 30, respectively, to secure the bag 4 thereto with the bag wall 6 largely suspended beneath the holder 10, as shown in phantom lines in Figures 1 and 6.
Once the bag 4 has been installed to the frame 12, the side frame members 40 can be collapsed by manually pushing the front frame member 30 toward the rear frame member 20, to move the front frame member 30 to the closed position, as shown in Figures 2 and 3. In the fully closed position of the embodiment of Figure 1, the bottom edges of the extension portions 30a of front frame member 30 rest in the depressions 34c in the upper edges of clips 34. In the embodiment of Figure 6 the magnet 22 magnetically attaches to the front frame member 30 to retain the holder 10 in the closed position, and the resilient strip 26 compresses the bag wall 6 against the bottom edge of the front frame member 30 to substantially seal the bag 4.
To open the holder 10 for depositing trash into the bag 4, the front frame member 30 is manually drawn away from the rear frame member 20, using sufficient force to overcome the engaging force of ledges 34b in the embodiment of Figure 1 (or the magnetic attraction in the embodiment of Figure 6), and the side frame members 40 are thus extended as the front frame member 30 moves to the open position shown in Figure 1. Opening the frame 12 in this fashion tensions and thus straightens the bag wall 6, fully exposing the top opening 8 of the bag 4 for use.
A preferred embodiment of the invention having been thus described by way of example only, it will be apparent to those skilled in the art that certain modifications and adaptations may be made without departing from the scope of the invention, as set out in the appended claims. The invention has been described in the context of its use as a trash or refuse container in a workspace, however it will be appreciated that the bag holder of the invention can be used in other environments and for other purposes without departing from the scope of the invention.

The present invention further provides, in combination, a flexible bag having a flexible bag wall and a top opening, and a collapsible holder for mounting to a supporting structure, the holder comprising a frame comprising: a stationary rear frame member, a movable front frame member, movable between an open position spaced from the rear frame member to retain the top opening in an open condition, and a closed position substantially abutting the rear frame member to retain the top opening in a closed condition, and opposed folding side frame members, each side frame member having an intermediate hinge and hingedly affixed to ends of the front and rear frame members, wherein when the holder is mounted to a supporting structure and the top opening of a bag is affixed to the frame, the side frame members can be collapsed to move the front frame member to the closed position and can be extended to move the front frame member to the open position.
In further aspects of the invention, the frame is mounted to a bracket affixed to the supporting structure, the bracket providing clips which detachably lock under the front frame member to releasably retain the frame in a collapsed position; the frame is composed of metal; one of the front frame member or the rear frame member comprises a flange which underlies the other of the front frame member or the rear frame member when the frame is in the closed position; the flange is provided along the rear fr~~rne member and the flange or a bottom portion of the front frame member, or both, is provided with a resilient strip which compressibly engages against the bag wall when the frame is in the closed position; the intermediate hinges are disposed generally centrally along the side frame members; the holder further comprises retaining strips for retaining the bag wall on the frame, which may extend along top edges of the front and rear frame members and may comprise resilient channels which compressibly engage the bag wall against the frame members; and/or the frame is removably mounted to a bracket by opposed slots in the bracket spaced from the supporting structure and adapted to receive the rear frame member.

Detailed Description of the Invention Figure 1 illustrates a preferred embodiment of the collapsible holder 10 of the invention, mounted to a supporting structure 2, such as a wall, table top, pegboard etc., and supporting a trash bag 4 (shown in phantom lines) having a flexible bag wall 6 and a top opening 8. The holder 10 comprises a frame 12 comprising a stationary rear frame member 20, a movable front frame member 30 and opposed folding side frame members 40.
In the preferred embodiment the frame 12 is composed of steel, however the frame 20 may be composed of any other suitably rigid material including other metals such as aluminum, plastic, wood, or any combination thereof.
The frame 12 may be provided with any suitable mounting means for mounting the holder 10 to a supporting structure 2. In the embodiment shown mounting means comprises a bracket 32 from which projects generally forwardly clips 34 which removably receive the rear frame member 20, as described below. This provides the advantage that the frame 12 is readily removable for cleaning or relocation; however the frame 12 may be mounted in any other suitable fashion.
Each side frame member 40 has an intermediate hinge 42 which allows the side frame members 40 to fold at an intermediate point, preferably generally centrally.
The side frame members 40 are also hingedly affixed to the ends of the rear and front frame members 20, 30 at hinges 44, 46, respectively. This allows the side frame members 40 to collapse, preferably inwardly to conserve space, so that the front frame member 30 is movable between an open position spaced from the rear frame member 20 to retain the top opening in an open condition, as shown in Figure 1, and a closed position substantially abutting the rear frame member 20, as shown in Figure 3, to retain the top opening 8 of the bag 4 in a closed condition. The side frame members 40 are preferably restricted from extending to 180 degrees, to ensure that they collapse inwardly merely by movement of the front frame member 30. The front frame member 30 may optionally be provided with a handle 38 to facilitate opening and closing the holder 10.
According to the preferred embodiment the clips 34, best seen in Figure 4, each project generally forwardly from an end of the mounting bracket 32 and provide a slot 34a into which a portion 20a of the rear member 20 is slidably disposed, to mount the frame 12 to the bracket 32. In the preferred embodiment the clips 34 further provide a ledge 34b having a top edge with a depression 34c in which a portion 30a of the front frame member 30 rests when the frame 12 is in the closed condition, as shown in Figure 3, to thus retain the frame 12 in the closed condition under the weight of the bag 4 and its contents.
In a further embodiment one of the front frame member 30 or the rear frame member 20 may be provided with a magnet 22 affixed by epoxy or any other suitable means. In this embodiment the frame 12 preferably is composed of or comprises a magnetic material, so that when the holder 10 is moved to the closed position shown in Figure 3, magnetic attraction between the magnet 22 and the rear or front frame member 20 or 30 retains the frame 12 in the closed position. If the frame 12 is not composed of a magnetic metal, a separate piece of magnetic material can be affixed to the frame 12 opposite the magnet to allow the frame 12 to be magnetically retained in the closed position. Other means may be used to retain the holder in the closed position.
The invention also provides means for sealing the bag 4 when the holder 10 is in the closed position. In the embodiment of Figure 6, the bottom edge of the rear frame member 20 comprises a flange 24, which is preferably formed integrally with the rear frame member 20 and underlies the front frame member 30 when the frame 12 is in the closed position. Thus, in the closed condition the bag wall 6 passes between the lower edge of the front frame member 30 and the upper surface of the flange 24.
In the preferred embodiment the flange 24 is provided with a resilient strip 26, for example a compressive urethane foam strip such as is used as weather stripping, extending along the flange 24, preferably along substantially its entire length. The strip 26 compressibly engages against the bag wall 6 when the frame 12 is in the closed position to substantially seal the bag 4 and thus retain unpleasant odors within the bag 4. This can be advantageous in the case of decomposable refuse, such as organic matter, or chemical refuse such as rags or paper litter used for cleaning oil-based solvents or the like. It will be appreciated that the resilient strip 26 could instead be disposed along a bottom portion of the front frame member 30, or resilient strips 26 could be disposed along both the flange 24 and the front frame member 30 to seal the bag 4 in a similar fashion. It is also possible to position the flange 24 so that there is a tight fit between the flange 24 and the bottom edge of the front frame member 30, or to provide a bead or recess which the bottom edge of the front frame member 30 abuts in the closed position, but these rigid sealing structures are not preferred because repeated closing and opening of the holder 10 could tear the bag wall 6.
The flange 24 may alternatively be provided along the lower edge of the front frame member 30, to underlie the rear frame member 20 when the frame 12 is in the closed position, although this is not preferred as it may require that the frame 12 be spaced too far from the supporting structure 2 in order to accommodate the flange 24 as the frame 12 is collapsed to the closed position.
The invention may include means for securing the bag 4 to the holder 10. In the preferred embodiment retaining strips 50, 52 are provided for retaining the bag 4 on the frame 12. Preferably the retaining strips 50, 52, comprising resilient channels, extend along the top edges of the rear and front frame members 20, 30, respectively, to compressibly engage the bag wall 6 against the frame members 20, 30. The rear retaining strip 50 may optionally have a backstop flap SOa covering any space between the rear frame member 20 and the supporting structure 2, as shown in Figure 1, and the front retaining strip 52 may optionally have a cover flap 52a covering the space between the front frame member 30 and the rear frame member 20 when the frame 12 is closed, as shown in Figure 3.
In use, the holder 10 is mounted to a supporting structure 2 by fastening mounting bracket 32 to any convenient support structure 2 such as a wall, worktable etc., as by screws or any other suitable fastener, and engaging the extension portions 20a of the rear frame member 20 into the slots 34a. With the frame 12 in the open position shown in Figure 1, the bag 4 is affixed to the frame 12 by inserting the bag 4 through the frame 12, folding the bag wall 6 about the top opening 8 over the rear and front frame members 20, 30, and slip-fitting the retaining strips 50, 52 over the top edges of the rear and front frame members 20, 30, respectively, to secure the bag 4 thereto with the bag wall 6 largely suspended beneath the holder 10, as shown in phantom lines in Figures 1 and 6.
Once the bag 4 has been installed to the frame 12, the side frame members 40 can be collapsed by manually pushing the front frame member 30 toward the rear frame member 20, to move the front frame member 30 to the closed position, as shown in Figures 2 and 3. In the fully closed position of the embodiment of Figure 1, the bottom edges of the extension portions 30a of front frame member 30 rest in the depressions 34c in the upper edges of clips 34. In the embodiment of Figure 6 the magnet 22 magnetically attaches to the front frame member 30 to retain the holder 10 in the closed position, and the resilient strip 26 compresses the bag wall 6 against the bottom edge of the front frame member 30 to substantially seal the bag 4.
To open the holder 10 for depositing trash into the bag 4, the front frame member 30 is manually drawn away from the rear frame member 20, using sufficient force to overcome the engaging force of ledges 34b in the embodiment of Figure 1 (or the magnetic attraction in the embodiment of Figure 6), and the side frame members 40 are thus extended as the front frame member 30 moves to the open position shown in Figure 1. Opening the frame 12 in this fashion tensions and thus straightens the bag wall 6, fully exposing the top opening 8 of the bag 4 for use.
A preferred embodiment of the invention having been thus described by way of example only, it will be apparent to those skilled in the art that certain modifications and adaptations may be made without departing from the scope of the invention, as set out in the appended claims. The invention has been described in the context of its use as a trash or refuse container in a workspace, however it will be appreciated that the bag holder of the invention can be used in other environments and for other purposes without departing from the scope of the invention.
