DESCRIPTION OF THE INVENTION
FIGS. 1-9 depict an apparatus 10, 300, 500, for supporting a person having several features that enhance the value, usefulness, reliability, portability and durability. The devices are generally, though not exclusively, used by the elderly with limited mobility.
FIG. 1 depicts an isometric view of the apparatus 10 having enhanced portability which enables a user to more easily, safely and comfortably support himself (with or without assistance) in a shower or bath tub 18. The apparatus 10 comprises: a rotatable and/or slidable chair 22 and the bathtub or shower 18. The rotatable and/or slidable chair 22 depicted in FIGS. 1-2, and described in associated text, herein, comprises a back support 16, a seat 14, foldable arms 20, a foldable and/or rotatable yolk 24, a non-slip stabilizer 36, and an elongated base 12, the elongated base 12 being between the seat 14 and the bathtub or shower 18. The foldable arms 20 may fold into recesses 34 in the surface 340 of the seat 14.
FIG. 2 depicts a horizontal cross-sectional view of the apparatus 10 having enhanced portability taken along line 2-2 of FIG. 1. In one embodiment, the rotatable and/or slidable chair 22 may be adapted to slide along the longitudinal axis 60 of the elongated base 12 or rotate on a slidable pivot 47 about an axis that is orthogonal to a surface 46 that may be parallel to the longitudinal axis 60 of the elongated base 12. The slidable pivot 47 may be a ball and socket type, or a swivel and pin or axle type. Hereinafter, “operably coupled or “operably coupling” is defined as linking or mechanically and physically attaching a first supporting structure, such as the rotatable and/or slidable chair 22 to a second supporting structure, such as the elongated base 12, so that the first supporting structure may freely rotate about an axis of the second supporting structure and/or slide along a longitudinal axis of the second supporting structure.
In another embodiment, the rotatable and/or slidable chair 22 may be mechanically and physically attached to the elongated base 12.
The rotatable and/or slidable chair 22 may, in one embodiment, have a foldable back support 16 and foldable arms 20 operably coupled to the rotatable and/or slidable chair 22 for back support and arm support, respectively, of the user.
In one embodiment, the rotatable and/or slidable chair 22 of the apparatus 10 may be made of hollow molded plastic, such as, for example, flexible plastic, curable silicone elastomer, organic elastomer, such as polyester or polyurethane, viton, sanoprene, or Ethylene-Propylene-Diene Monomer (EPDM). Alternatively, the rotatable and/or slidable chair 22 of the apparatus 10 may be made of wood, or light metals such as, for example, aluminum.
The elongated base 12 has a first end 56 and a second end 54. A foldable and/or rotatable yolk 24 may be operably coupled to the first end 56 and a stabilizer 36 the second end 54 may be operably coupled to the second end 54. Hereinafter, “operably coupled” or “operably coupling” means linking or mechanically and physically attaching the foldable and/or rotatable yolk 24 or the rotatable and/or slidable chair 22 to the elongated base 12, wherein the axis of rotation of the foldable and/or rotatable yolk 24 and rotatable and/or slidable chair 22 is orthogonal to a longitudinal axis 60 of the elongated base 12.
The foldable and/or rotatable yolk 24 and the non-slip stabilizer 36 may be made from any appropriate solid material characterized by non-slip properties, such as vulcanized rubber, or flexible plastic, curable silicone elastomer, organic elastomer, such as polyester or polyurethane, viton, sanoprene, or Ethylene-Propylene-Diene Monomer (EPDM).
In one embodiment, the foldable and/or rotatable yolk 24 may have gripping arms 26, 28 for physically and mechanically gripping an outer surface 58 and the inner surface 59 of a wall 40 of the shower or bath tub 18, respectively.
In one embodiment, the non-slip stabilizer 36 may lie on a surface 32 of a wall 38 of the shower or bath tub 18, thereby supporting the base 12 and the rotatable and/or slidable chair 22 thereon.
In one embodiment, the apparatus 10 comprises a shower or bath tub 18. The stabilizer 36 on the second end 54 of the elongated base 12 may be a non-slip stabilizer 36 operably coupled to a surface 42 of the second end 54 of the elongated base 12, so that slippage of the elongated base 12 and the whole apparatus 10 in a direction orthogonal to the longitudinal axis of the elongated base is substantially prevented when the non-slip stabilizer 36 lies on a supporting surface 32 of the wall 38 of the shower or bath tub 18, thereby essentially completely stabilizing the second end 54 of the elongated base 12 and the rotatable and/or slidable chair 22, thereon.
In one embodiment, the foldable and/or rotatable yolk 24, in a tub-supported model, enables a secure fixing of the rotatable and/or slidable chair 22 in a specific location along the surfaces 32, 44, 58, 59, of the tub wall 40, without marring the tub surfaces 32, 44, 58, 59.
In one embodiment, the foldable and/or rotatable yolk 24 may pivot between about 0 and about 360° on a pivot device 191, wherein an axis of rotation of the pivot device 191 is orthogonal to a surface 42 of the elongated base 12 that is parallel to the longitudinal axis 60, so that the foldable and/or rotatable yolk 24 may fold into recess 190 of the elongated base 12 so that an overall height of the rotatable and/or slidable chair 22 is reduced between about 20% and about 50% when the foldable and/or rotatable yolk 24 of the rotatable and/or slidable chair 22 is folded into the recess 190 of the elongated base 12.
Alternatively, the foldable and/or rotatable yolk 24 may be replaced by a second non-slip stabilizer similar to the non-slip stabilizer 36, resulting in non-slip stabilizers 36 on both ends 54 and 56 of the elongated base 112. The non-slip stabilizers 36 on both ends 54 and 56 operably coupled to a surface 42 of the first and second ends 54 and 56 of the elongated base 12, so that slippage of the elongated base 12 and the whole apparatus 10 in a direction orthogonal to the longitudinal axis of the elongated base is substantially prevented when the non-slip stabilizers 36 lie on a supporting surfaces 32, 44 of the walls 38 and 40 of the shower or bath tub 18, thereby essentially completely stabilizing the first and second ends 54 and 56 of the elongated base 12 and the rotatable and/or slidable chair 22, thereon.
Alternatively, the elongated base 12, depicted in FIG. 2 and described in associated text, herein, may be supported by legs 52 that may be directly supported by and lie on the bottom surface 50 of the shower or bath tub 18. In one embodiment, the apparatus 10, comprises a slidable and/or rotatable chair 22 having a seat 14 operably coupled to the elongated base 114. Legs 52 of the elongated base 114 may fold into recesses 187 in the elongated base 114, so that a surface 51 of the legs 52 may become flush or coplanar with the surface 42 of the elongated base 12. The rotatable and/or slidable chair 22 may have a smaller three dimensional volume, based on the length, depth and height of the rotatable and/or slidable chair 22 when the legs 52 and the rotatable and/or foldable yolk 24 may be folded into the recesses 42 and 190, respectively. In one embodiment, the three dimensional volume of the rotatable and/or slidable chair 22 is 1,080 cubic inches when elongated base 114 is 36 in. long×20 in. high×15 in. deep, when the legs 52 are extended under the elongated base 114 to support it. The three dimensional volume of the rotatable and/or slidable chair 22 is 720 cubic inches when elongated base 114 is 36 in. long×20 in. high×1 in. deep, when the legs 52 are collapsed under the elongated base 114 for easier and more comfortable and safe transporting or carrying the rotatable and/or slidable chair 22. The three dimensional volume of the rotatable and/or slidable chair 22 may be reduced by 720 cubic inches/1,020 cubic inches, or about 31%.
FIG. 3A depicts an elevation view of an apparatus 10, 300, having enhanced portability, which enables a user to more easily, safely and comfortably support himself (with or without assistance) in a shower or bath tub 109. The apparatus 10, 300, comprises: a rotatable and/or slidable chair 115; and a bathtub or shower 109. The rotatable and/or slidable chair 115 comprises an elongated base 114; and a foldable chair 96.
The elongated base 114 has an upper surface 83 and a parallel oppositely disposed lower surface 79. The bottom surface 85 of the seat 87 of the rotatable and/or slidable chair 115 and the upper surface 83 of the elongated base 114 form an interface 81 that lies in a longitudinal plane defined by the points A, B, C, and D that lie in the surface 83 of the elongated base 114. Therefore, the upper surface 83 of the elongated base 114 supports the seat 87 because the lower surface 85 of the seat 87 lies on the upper surface 83 of the elongated base 114. The rotatable and/or slidable chair 115 may be supported by the walls 105 of the bathtub or shower 109 because the lower surface 79 of the elongated base 114 lies on the surface 77 of the walls 105 of the bathtub or shower 109.
A grooved channel 116, having grooves 117 has been cut into a bottom surface 85 of the seat 87 of the rotatable and/or slidable chair 115. A slidable pivot connector 118 running along the longitudinal axis 107 of the grooved channel 116, may operably couple the elongated base 114 and the seat 87 of the foldable chair 96. The slidable pivot connector 118 may be a pin or axle 120 having a concentric collar 111. Hereinafter, “operably coupling” or “operably coupled” is defined as linking or mechanically and physically attaching a first supporting structure, such as the rotatable and/or slidable chair 115 to a second supporting structure, such as the elongated base 114, so that the first supporting structure may freely rotate in a direction of the arrow 89 about a vertical axis running perpendicularly to a longitudinal plane of the second supporting structure and/or slide in a direction of the bidirectional arrow 110 along the longitudinal plane of the second supporting structure.
The slidable pivot connector 118 comprises a pin or axle 120 having a concentric collar 111, the pin or axle 120 having a longitudinal axis that is orthogonal to the longitudinal axis 107 of the rotatable and/or slidable chair 115. Referring to FIG. 6, the pin or axle 120 extends from a well 9 within the elongated base 114 into the grooved channel 116 that lies within the seat 87 of the rotatable and/or slidable chair 115 and runs along the longitudinal axis 107. The slidable pivot connector 118 may be a pin or axle 120 having a concentric collar 111. When the slidable pivot connector 118 is a pin or axle 120 having the concentric collar 111, the pin or axle 120 runs along the slot 116 and the concentric collar 111 runs along the grooves 117 both of which run along the longitudinal axis 107, operably coupling the rotatable and/or slidable chair 115 to the elongated base 114. Hereinafter, “operably coupling” or “operably coupled” is defined as linking or mechanically and physically attaching a first supporting structure, such as the rotatable and/or slidable chair 115 to a second supporting structure, such as the elongated base 114, so that the first supporting structure may freely rotate in a direction of the arrow 89 about a vertical axis running perpendicularly to a longitudinal plane of the second supporting structure and/or slide in a direction of the bidirectional arrow 110 along the longitudinal plane of the second supporting structure. The slidable pivot connector 118 may be a type of connector used in a lazy susan for operably coupling a rotatable tray and a supporting structure. Hereinafter, a “lazy susan” is defined as a rotatable tray used for serving food, condiments, or relishes. The tray may rotate on a pin or axle 120. The slidable pivot connector 118 may be a ball and socket connector, in which one end of the ball and socket may be inserted into the surface 83 of the elongated base 114, and another end of the ball and socket may be attached to the seat 87 of the foldable chair 96. Alternatively, the slidable pivot connector 118 may be a swivel and pin or axle connector, having a pin or axle 120 inserted into the surface 83 of the elongated base 114, or into the surface 85 of the seat 87, so that the ball and socket connector or the swivel and pin or axle connector operably couples the first and second supporting structures, such as the rotatable and/or slidable chair 115 and the elongated base 114.
FIG. 3B depicts an exploded view of the foldable chair 96 of the rotatable and/or slidable chair 115. In one embodiment, the rotatable and/or slidable chair 115 of the apparatus 10, 300 enables a user to more easily, safely and comfortably gain access to the rotatable and/or slidable chair 115 to support himself (with or without assistance) in a shower or bath tub 109 by sliding along the grooved channel 116 in the direction of the bidirectional arrow 91 along the longitudinal plane defined by the points A, B, C, and D on the surface 83 of the elongated base 114.
The foldable chair 96 comprises: a foldable back support 80, a seat 87 and foldable arms 82. The foldable back support 80 may be operably coupled, using operable coupling 6, to the seat 87, so that the foldable back support 80 may fold along axis 1 in the direction of the bidirectional arrow 2. The operable coupling 6 may be at least one hinge or any appropriate flexible joint that may operably couple the foldable back support 80 to the seat 87. Folding along axis 1 may provide a more compact foldable chair 96 because the volume of the foldable chair 96 is reduced when the foldable back support 80 folds in the direction of the bidirectional arrow 2 along axis 1. This may enable more easy transportation of the rotatable and/or slidable chair 115.
The seat 87 has an upper surface 92 and a parallel oppositely disposed bottom surface 85. The foldable arms 82 may fold in the direction of the bidirectional arrow 3 into recesses 5 in the surface 92 of the seat 87 so that an upper surface 4 of the foldable arms may become flush or coextensive with a plane of the surface 92 of the seat 87. In another embodiment, the rotatable and/or slidable chair 115 of the apparatus 10, 300, enables a user to more easily, safely and comfortably gain access to the rotatable and/or slidable chair 115 to support himself (with or without assistance) in a shower or bath tub 109 by rotating about the slidable pivot connectors 18 in a direction of the bidirectional arrow 89.
In one embodiment, the rotatable and/or slidable chair 115 comprise: the foldable back support 80, the seat 87 and foldable arms 82. In one embodiment, a height of the back support 80 from a plane formed by the surface 92 of the seat 87 is between about 8 in. and about 12 in. In one embodiment, a depth of the seat 87 along the plane formed by surface 92 is between about 12 and about 15 in. In one embodiment, a height of the foldable arms 82 from the plane formed by surface 92 is between about 6 and about 8 in.
In one embodiment, the seat 14, 87 of the rotatable and/or slidable chair 22, 115 of the apparatus 10, 300, has a wider front edge 48 than an edge 8 adjacent to the back 16, 80 of the rotatable and/or slidable chair 22, 115, and a flared front edge 3, extending the front edge 48 between about 15 inches and about 25 inches. In this embodiment, flared front edge 3 aids the user in initially sitting on the seat 87 by enlarging the area of the seat 87.
FIG. 4 depicts an elevation view of an embodiment of the foldable chair 96 of the rotatable and/or slidable chair 115 of the apparatus 10, 300, depicted in FIGS. 3A, 3B, and described in associated text herein, having enhanced portability which enables a user to more easily, safely and comfortably support himself (with or without assistance) in a shower or bath tub 109. The foldable chair 96 of the rotatable and/or slidable chair 115 comprises a foldable back support 80, a seat 87, and foldable arms 82.
The foldable back support 80 may be operably coupled to the seat 87 so that the back support 80 may be moved in either direction of the bidirectional arrow 86. When opening the foldable back support 80, a first surface 98 of the foldable back support 80 is moved away from the first surface 92 of the seat 87. When in the open position, a person's back may be comfortably supported by forming an angle 7 between the first surface 98 of the foldable back support and the first surface 92 of the seat 87 from about 90° to about 180°, the angle 7 being formed at 94 where the first surface 98 of the foldable back support 87 joins the first surface 92 of the seat 87.
When in a closed position, the first surface 104 of the foldable arms 82 and the first surface 98 of the foldable back support 80 are moved toward the recesses 84 and the first surface 92 of the seat 87, respectively. When in the closed position, an angle 7 between the first surface 98 of the foldable back support and the first surface 92 of the seat 87 may be from about 0° to about 90°, the angle 7 being formed at 94 where the first surface 98 of the foldable back support 87 joins the first surface 92 of the seat 87.
Closing the foldable arms 82 and the foldable back 80 enables more easy and convenient transportation of the rotatable and/or slidable chair 115 because the chair 96 occupies less volume in the closed position and therefore doesn't require as wide a path during transportation or storage. When in the closed position, the angle 7 may be 0° and an outer surface 102 of the foldable arms 82 may be flush with the first surface 92 of the seat 87 and the first surface 98 of the back support 80 may be flush with a first surface 92 of the seat 87. Hereinafter, “being flush with” is defined as the first surface 92 of the seat 87 being adjacent to the first surface 98 of the back support 80 or the outer surface 102 of the foldable arms 82 being coplanar with the first surface 92 of the seat 87.
The foldable back support 80 may be opened or closed by pivoting in a direction of the arrow 86 on any appropriate joining device 94 such as, for example, a hinge or a strip of rubber or plastic. The hinge may be made of plastic, rubber, or metal, such as brass, stainless steel, tin, copper, or alloys of steel, tin, chromium, nickel, or copper. The plastic may be flexible plastic, curable silicone elastomer, organic elastomer, such as polyester or polyurethane, viton, sanoprene, or Ethylene-Propylene-Diene Monomer (EPDM).
In the folded embodiment, the rotatable and/or slidable chair 115 of the apparatus 10, 300 has enhanced portability because the chair 115 becomes more compact when the back support 80 pivots in the direction of the arrow 86 so that it is flush with the first surface 92 of the seat 87. The folding back or folding forward aids in making the seat more portable by allowing a reduction in the overall height when folded.
In one embodiment, the rotatable and/or slidable chair 115 of the apparatus 10, 300 enables a user to more easily, safely and comfortably support himself (with or without assistance) in a shower or bath tub 109 because the joining device 94 may pivot and be lockable in place or fixed in orientation to form a fixed angle 7 between about 90° and about 180° with respect to the first surface 98 of the back support 80 and the first surface 92 of the seat 87. Solid Brass Butler lockable hinges that will lock in place at 90° and 180° are available from Van Dyke's Restorers, PO BOX 278, 39771 S.D. HWY. 34, WOONSOCKET, SD 57385, PHONE: (605) 796-4425.
The foldable arms 82 may be operably coupled to the seat 87 and fold or pivot into recessed grooves 84 by rotating in a direction of the arrow 88 so that an inner surface 104 of the foldable arms 82 may be coplanar with the first surface 92 of the seat 87, or an outer surface 102 of the foldable arms 82 may be flush with the first surface 92 of the seat 87, or the foldable arms 82 may be in any position therebetween with respect to the first surface 92 of the seat 87. Hereinafter, “being flush with” is defined as the first surface 92 of the seat 87 being adjacent to the first surface 98 of the back support 80 or being coplanar with an outer surface 102 of the foldable arms 82. The foldable arms 82 may function as recessed folding handles that enable the seat 87 to be more portable by allowing recessed storage of the foldable arms 82 without sacrificing the stability benefit they provide when the user uses the foldable arms 82 as handles to support himself or herself, for example, when initially sitting down on the seat 87 or moving on the seat 87 to wash.
The inner surface 104 of foldable arms 82 may be coplanar with the first surface 92 of the seat 87, or the outer surface 102 may be flush with the first surface 92 of the seat 87 or in any position therebetween by pivoting in a direction of the arrow 88 on any appropriate joining device 90 such as, for example, a hinge or a strip of rubber or plastic. The hinge may be made of plastic, rubber, or metal, such as brass, stainless steel, tin, copper, or alloys of steel, tin, chromium, nickel, or copper. The plastic may be flexible plastic, curable silicone elastomer, organic elastomer, such as polyester or polyurethane, viton, sanoprene, or Ethylene-Propylene-Diene Monomer (EPDM). In a folded embodiment, the rotatable and/or slidable chair 115 of the apparatus 10, 300, has enhanced portability because the rotatable and/or slidable chair 115 becomes more compact when the foldable arms 82 pivot in the direction of the arrow 88 so that the outer surface 102 of the foldable arms 82 become flush with the first surface 92 of the seat 87. In one embodiment, the rotatable and/or slidable chair 115 of the apparatus 10, 300, enables a user to more easily, safely and comfortably support himself (with or without assistance) in a shower or bath tub 18 because the joining device 90 may pivot and be lockable in place or fixed in orientation to form a fixed angle 6 between about 10° and about 260° with respect to the inner surface 104 of the foldable arms 82 and the first surface 92 of the seat 87. Solid Brass Butler lockable hinges that will lock in place at 90° and 180° are available from Van Dyke's Restorers, PO BOX 278, 39771 S.D. HWY. 34, WOONSOCKET, SD 57385, PHONE: (605) 796-4425.
