Field of the Invention
Embodiments of the present invention generally relate to transfer benches and, more particularly, to a transfer bench adapted to facilitate the movement into and out of an enclosure, such as a bathtub, by persons having limited mobility.
Description of the Related Art
Movement into and out of a wet environment, such as a bathtub, can be difficult for persons having limited mobility. Such movement, for a person with a standard level of mobility, normally requires a minimal amount of effort and care to maintain safety. However, for persons with limited mobility such as invalids, handicapped, disabled, or other persons with conditions that limit the functionality of muscles, the minimal amount of effort and care often precludes the safe use of a bathtub or other wet environment.
Currently known devices that may assist a person upon entry or exit of a wet environment do not adequately protect the safety of the person. For example, the devices may not allow for enclosure of the wet environment, such as by a door or curtain, and thus allow for water to spill beyond the periphery of the wet environment. This can further compromise the safety of the individual.
Thus, there is a need in the art for a device and methods of using same that facilitates the movement into and out of a wet environment while maximizing safety to an individual.
Embodiments of the present invention generally relate to transfer benches and, more particularly, to a transfer bench adapted to facilitate the movement into and out of an enclosure, such as a bathtub, by persons having limited mobility.
In one embodiment of the present invention, a transfer bench comprises a first seating section, a second seating section rotatably coupled to said first seating section and configured to rotate from and between a substantially horizontal position to a substantially vertical position, wherein the second seating section cannot rotate more than about 90 degrees from the horizontal position, a first plurality of legs configured to support the first seating section, a second leg configured to support the second seating section, and a back support member extending from a side of the first seating section perpendicular to an axis of rotation of the second seating section.
In another embodiment of the present invention, A bathtub assembly comprises a bathtub having an enclosure, the enclosure comprising a tub having a floor surface and sidewalls; and a transfer bench comprising: a first seating section; a second seating section rotatably coupled to said first seating section and configured to rotate from and between a substantially horizontal position to a substantially vertical position, wherein the second seating section cannot rotate more than about 90 degrees from the horizontal position; a first plurality of legs configured to support the first seating section, the first plurality of legs affixed to the tub; a second leg configured to support the second seating section; and a back support member extending from a side of the first seating section perpendicular to an axis of rotation of the second seating section.
In yet another embodiment of the present invention, a transfer bench comprises: a frame having a slidable rail positioned thereon, the frame having a first section and a second section; a slidable seating section affixed on the slidable rail for sliding from the first section to the second section; the second section rotatably coupled to said first section and configured to rotate from and between a substantially horizontal position to a substantially vertical position, wherein the second section cannot rotate more than about 90 degrees from the horizontal position; a first plurality of legs configured to support the first section; a second leg configured to support the second section; and a back support member extending from a side of the first section perpendicular to an axis of rotation of the second section.

According to various embodiments of the present invention, a transfer bench is disclosed for use in an enclosure having a base and a periphery of a predetermined height. In some embodiments, the enclosure may be a wet/dry environment, such as a bathtub, shower enclosure (such as a shower stall or shower closet), hot tub, pool, and the like. Optionally, the transfer bench can be used in any suitable environment. Thus, although use of a transfer device is illustrated in
The periphery of the enclosure, in some embodiments, may have a negligible predetermined height or a predetermined height of zero. For instance, many locker rooms and similar bathing environments have shower stalls with a base that is approximately level with the surrounding floor. Thus, in such shower stalls, at least a portion of the periphery may have a height of zero. In a traditional bathtub, the periphery may have a height of several inches to several feet. In various embodiments, the height of the periphery may vary along the length of the periphery. In further embodiments, the periphery may defined by a wall (such as in a bathtub), a lip, a shower curtain, a door (such as a door that swings open or slides along a track), other enclosing means, or any combination of these.
A transfer bench, according to one embodiment of the present invention, comprises a first seating section and a second seating section that is coupled to the first seating section. With reference to
In a particular embodiment, the second seating section 104 can be coupled or attached to the first seating section 102 in a rotatable manner and can be positioned from and between a first position and a second position. As illustrated in
The two seating sections can be coupled by various means that allow this movement. For example, the second seating section can be hingedly attached to the first seating section such as by one or more hinges 140. Optionally, the seating sections can be coupled by a pin and hole configuration, a pin and slot configuration, a detent and hole configuration, or any other manner that allows for relative rotational movement of the second seating section. Means can also be provided for selectively maintaining the second seating section in the second position, such as latching or other securing means. Either or both of the first and second seating sections can also comprise water drainage means to drain water from the respective surfaces when the transfer bench is used in a wet environment. Such water drainage means can include holes, slots, channels, or a combination thereof, configured and positioned in a manner that facilitates water drainage from the surface of the respective seating surface.
In one embodiment, the second seating section can comprise a handhold, such as for assisting in stabilizing the user, providing the user with means to move the second seating section from the first position to the second position, or for other purposes. The handhold can be a handle, an aperture 118 that extends through the second seating section, such as shown in
In one embodiment, other means can be provided to support a user, such as one or more arm rests, a back support, etc. The second seating section when in the vertical position can also support the user, such as by limiting lateral movement of the user or providing a support against which the user can lean or rest. In a particular embodiment, the first seating section can comprise a first edge and an opposing edge. The second seating section can be rotatably coupled to the first seating section proximate the first edge, and an arm rest can be positioned proximate the second edge. In yet another embodiment, the transfer bench can comprise a back support. The back support can extend from the first seating section at a selected angle. For example, the back support can extend substantially vertically upward from the first seating section. Optionally, the back support can extend at an angle selected at or between horizontal and vertical to allow the user to lie back against the back support. In yet another embodiment, the back support can have means for adjusting the angle relative to the first seating section to allow the user to position the back support means to any angle. In some embodiments, one or more arm rests and a back support can be provided. Thus, the transfer bench can comprise arm rest(s), a back support, or both. In any embodiment in which an arm rest and/or back support is provided, the arm rest(s) and/or back support can be removably attached to the transfer bench. Means can also be provided for attaching the back support proximate one or more edges of the first seating section so that the transfer bench can be used in various enclosures. Optionally, the arm rest(s) and/or back support can be fixedly attached to the transfer bench.
The first and second seating sections are shown as substantially rectangular in
In a further embodiment, a plurality of support means is provided to support each of the first and second seating sections. The support means, in one embodiment, are at least as tall as the predetermined height of the periphery of the enclosure. For example, as shown in
In the particular embodiment in which the first seating section is supported by four legs and the second seating section is supported by two legs, when the second seating section is in a generally horizontal position and is substantially coplanar with the first seating section, the transfer bench will be supported by at least six legs. When the second seating section is in a generally vertical position or between the generally horizontal and generally vertical positions, the transfer bench will be supported by the at least four legs supporting the first seating section. In any embodiment, each leg can have rubber, soft plastic, suction cup, or other material or means disposed at a foot or distal end of the leg to absorb shock, stabilize the leg, and/or protect the finish of the surface on which the transfer bench is supported. Additional stability can be provided through stiffening members attached or mounted between two or more legs. For example, as shown in
According to various embodiments, each leg can have a selectively adjustable height such that it can be extended and retracted. For example, each leg can be telescoping, pads on the feet or distal ends of the legs can be adjusted to various lengths (e.g., as by screw-type rotation), or each leg can be secured at various lengths through the use of a cotter-pin or other pin or detent-type assembly. In a particular embodiment, each leg can be individually adjustable. The transfer bench can thus be used in environments with uneven, sloped, or staggered-height surfaces and the first seating section can be maintained in a generally horizontal position to provide increased safety to the user. Likewise, when the second seating section is in the first position, it can lie in a substantially coplanar and horizontal orientation with relation to the first seating section. It is contemplated that the transfer bench can have legs that are of a height that is at least as tall as the predetermined height of the periphery. In various embodiments, one or more legs can be rotatably coupled to the first and/or second seating section. For example, in a particular embodiment, the leg(s) 110 supporting the second seating section 104 can be rotatably or hingedly coupled to the second seating section. As shown in
In use, methods are disclosed for facilitating movement of a person into and out of an enclosure. The method comprises providing a transfer bench, such as described above according to various embodiments. For example, with reference to
The second seating section can be configured to rotate from and between a first, generally horizontal, position and a second, generally vertical position. The method can further comprise positioning the second seating section to the first position, such that at least a portion of the second seating section extends beyond the periphery of the enclosure. For example,
Legs supporting the first and second seating sections can be individually and selectively adjustable in height. The legs 108 supporting the first seating section can be manipulated to adjust the height of the first seating section, such that the legs are at least as tall as the predetermined height of the periphery. For example, in use in a bathtub, the legs can be adjusted to position the first seating section at a height that is at least as high as the wall of the bathtub, such that the second seating section can extend across the periphery without obstruction when in the first position. The legs can be adjusted, for example, if the base of the enclosure is uneven, sloped, etc., so that the first seating section can be maintained in a generally horizontal plane. The leg(s) supporting the second seating section can also be selectively adjusted. For example, if the floor surface outside of the enclosure is at a different level than the height of the base of the enclosure, the legs can be extended or retracted to maintain the first and second seating section in a substantially horizontal and coplanar arrangement when the second seating section is in the first position.
The method can further comprise receiving the person on the second seating section. The person can then be transferred to the first seating section. For example, a user of the transfer bench can sit on the second seating section and move to the first seating section by lifting each of the user's legs over the periphery of the enclosure (such as but not limited to a bathtub wall) and sliding or shifting toward the first seating section.
The method can further comprise rotating the second seating section from the first position to the second position, such as indicated by the arrows in
Latching or securing means can be provided and/or manipulated to maintain the second seating section in the generally vertical position. Enclosure means can then be manipulated to at least partially enclose the enclosure, such as shown in
To exit the enclosure, the person can manipulate the enclosure means to a position that allows the second seating section to be extended to a generally horizontal position. The second seating section can be rotated to this position and the person can move from the first seating section to the second seating section in a reverse manner than that described above.

The legs 808 of the first section 802 may generally be vertically positioned underneath the first section 802, such that the legs 808 support a predetermined maximum weight/load placed on the first section 802. In many embodiments, the legs 808 may be telescopic, or otherwise extendible, such that the legs 808 and the overall height of the transfer bench 800 can be adjusted for various applications. In such embodiments, the extendible feature may comprise a spring loaded button and slot system, a threaded extension system (i.e., which may be rotated along threads to raise or lower each leg), a clamp-type using a screw/bolt or similar mechanical device to hold an otherwise moveable leg in place within a sleeve, or the like. As shown in the Figure, the legs 808 may comprise a stiffening member 812, or similar structure, to support the load placed on the legs 808.
The at least one leg 810 of the second section 804, may generally be vertically positioned underneath the second section 804, such that the leg 810 can support a predetermined maximum weight/load placed on the second section 804. In many embodiments, the leg 810 may be telescopic, or otherwise extendible, as described above with legs 808. Generally, any telescopic or extension features of the legs 808 are also provided on leg 810 such that the transfer bench 800 remains level.
In many embodiments, a leg 810 may be collapsible, such that the leg 810 may rotate from a substantially vertical position, as shown in the Figure, to a flat position against the bottom surface of the second section 804. In such embodiments, the leg 810 may be substantially locked in a vertical position via an extension member 822, which may be substantially rigid, on a bottom surface of the second seating section 804, and may not be released and rotatable until a release mechanism 828 is activated. A release mechanism 828 may disengage/unlock an engaged/locked extension member 822 to allow rotation of the second seating section 804.
In some embodiments, the release mechanism 828 may comprise a handle disposed generally in a center portion between the first section 802 and the second section 804. A release mechanism 828 may be positioned on or around the first section 802 and the second section 804 in a location that allows a patient or user to activate the release mechanism 828 while seated on the first section 802 or the second section 804. In some embodiments, the release mechanism 828 may comprise lever, handle, a trigger, switch, and/or the like connected to a handle, or the like, positioned in a center portion between the first section 102 and the second section 804. In some embodiments, a release mechanism 288 may be positioned in alternative locations, such as on an outer edge of the first section 802, on an edge of the second section 804, in any suitable location for releasing the extension member 822, and/or the like. In some embodiments, the extension member 822 may comprise a bar adapted to pull at least one leg 810 into a closed position during rotating of the second section 804.
In some embodiments, the bench 800 may comprise a flap 826, or the like, that may substantially cover any gap between the first section 802 and the second section 804 on a top surface of the bench 800, thereby improving comfort of the user.
