[0014] [1] A mobility aid using a stretcher as an example of an embodiment of the present invention will be described with reference to the drawings.

[0015] (1) The stretcher-like mobility aid A of the first embodiment spans the tops of a bed D (first object) for the person being cared for, located at the rear side with a horizontal gap between them and a portable bathtub T for care use (second object) located at the front side with a longitudinal direction running left and right, and is made mainly of steel plates.

[0016] (2) A stretcher-like mobility aid A has an upper surface portion having an inclined upper surface portion A1 at the front part including the front end, and a horizontal upper surface portion A2 behind the inclined upper surface portion A1.

[0017] A left-right stretcher S (which can be used when bathing in a portable bathtub) carrying the subject can be temporarily placed on the upper surface as necessary or slid forward and backward relative to the upper surface, and then transported forward and backward on the upper surface in a non-contact or contacting state with the upper surface to move it between the bed D and the portable bathtub T.

[0018] (3) At a position slightly rearward of the front end of the stretcher-type mobility aid A, there is an upwardly concave fitting recess A3 for fitting downwardly onto the upper edge F1 of the portable bathtub T (the portion along the horizontal straight line in the left-right direction on the back side of the upper frame part F provided above the upper edge T1 of the portable bathtub T). The fitting recess A3 is located at two points on the left and right ends and at two points on the left and right inner parts of a specified length in the left and right direction, spaced apart from each other along the straight line in the left and right direction.

[0019] (4) When the stretcher-like mobility aid A is suspended between the top of the bed D and the upper edge portion F1 (upper portion) of the portable bathtub T, the inclined upper surface portion A1 is flat and slopes downward toward the front from near the middle of the fore-and-aft position of the mating recess A3, and the horizontal upper surface portion A2 is approximately horizontal.

[0020] (5) In the mobility aid A of the stretcher of the present invention, the portion excluding the inclined upper surface portion A1 is a flat plate-like portion A2a along a substantially horizontal plane in the state of being stretched as described above, and a frame-like reinforcement portion A4 is formed on the outer periphery below the flat plate-like portion A2a, and two places on the left and right inner portions are reinforced by front-rear direction reinforcement portions A5 consisting of a bottom plate and both side plates. The frame-like reinforcement portions A4 on both sides of the flat plate-like portion A2a are formed so that their height decreases toward the rear as shown in Fig. 3.

[0021] When suspended as described above, the inclined upper surface portion A1 is an inclined plate-shaped portion A1a which is reinforced on the lower side by left and right inclined side plates A6, and two points on the left and right inner portions are reinforced by left and right directional reinforcement portions A7 consisting of a bottom plate and both side plates.

[0022] (6) The mating recess A3, which is located slightly rearward of the front end of the stretcher-type mobility aid A, is fitted downwardly onto the upper edge-like portion F1 of the portable bathtub T and the rear portion is placed on the bed D. When the stretcher-type mobility aid A is placed across the tops of the bed D and the portable bathtub T, the frame-shaped reinforcement portions A4 on both sides of the flat portion A2a decrease in height toward the rear, thereby minimizing the occurrence of a step on the bed D caused by the stretcher-type mobility aid A.

[0023] (7) The stretcher-type mobility aid B of the second embodiment is The width in the left-right direction is about half that of the stretcher-type mobility aid A of the first embodiment, The left mobility aid BL and the right mobility aid BR, each having one front-rear reinforcement B5 and one left-right reinforcement B7, are connected in parallel by fitting upward the L-shaped cross-sectional connection N on the right side of the left mobility aid BL into the left side of the right mobility aid BR to form a stretcher-type mobility aid B. Except for the above, this embodiment is the same as the first embodiment. Note that the left movement auxiliary device BL and the right movement auxiliary device BR, which do not have the connection portion N, can also be used in parallel.

[0024] In the stretcher-type mobility aid B (including the left mobility aid BL and the right mobility aid BR), the same reference numerals indicate the corresponding parts in the stretcher-type mobility aid A, except that A is replaced by B.

[0025] (8) The stretcher-like mobility aid C of the third embodiment is lightweight because most of its surface is made of carbon fiber.

[0026] In stretcher-type mobility aid C, the same reference numerals indicate corresponding parts in stretcher-type mobility aid A, except that A is replaced by C. However, frame-shaped reinforcement C4 is also provided in the front of flat plate-shaped part C2a, and inclined plate front reinforcement C8 and inclined plate rear reinforcement C9 are provided in the front and rear of inclined plate-shaped part C1a, respectively. Frame-shaped reinforcement C4 in the front of flat plate-shaped part C2a and inclined plate rear reinforcement C9 form fitting recess C3 that continues in the left-right direction across the left and right ends of stretcher-type mobility aid C.

[0027] [2] The following further describes the embodiment of the stretcher-type mobility aid of the present invention, including embodiments other than those described above.

[0028] (1) The mobility aid of the stretcher of the present invention is a bridge between the upper parts of a first object (e.g., a bed [bed platform] for a person receiving care or a patient, with a longitudinal direction running left and right) located on the rear side with a horizontal gap between them and a second object (e.g., a portable bathtub, particularly a portable bathtub suitable for a person receiving care or a patient, with a longitudinal direction running left and right) located on the front side, and has an upper surface and an upwardly concave mating recess. The mobility aid of the stretcher of the present invention can be, for example, one made mainly of steel plate, one made mainly of synthetic resin material or other material reinforced or reinforced with carbon fiber or other material to reduce weight, or one made of at least a part or all of the surface layer made of carbon fiber to reduce weight, but is not limited to these.

[0029] (2) The upper surface of the stretcher-type mobility aid of the present invention has an inclined upper surface portion at the front including the front end, and a horizontal upper surface portion behind the inclined upper surface portion.

[0030] The upper surface can be used to transport a left-right stretcher (e.g., one that can be used when bathing in a bathtub) carrying a subject, between a first object and a second object, by temporarily placing it on the upper surface or sliding it back and forth relative to the upper surface as necessary.

[0031] (3) At a position slightly rearward of the front end of the front surface, there is an upwardly concave mating recess that can be fitted downward onto an upper edge-like portion that follows a horizontal straight line in the left-right direction of the second object (it is not necessary that the entire upper edge-like portion follows a horizontal straight line in the left-right direction).

[0032] For example, in a case where the first object is a bed arranged with its longitudinal direction in the left-right direction on the rear side, and the second object is a bathtub such as a portable bathtub arranged with its longitudinal direction in the left-right direction on the front side, the upper edge-like part along the horizontal straight line in the left-right direction of the second object can be the rear side part of the upper edge part of the portable bathtub on the rear side, or a frame-like part (for example, a frame-like part for assistance, a frame-like part as a handrail for the person being assisted or the patient, etc.) provided above the upper edge part. Including such an example, a part of the frame-like part can be the upper edge-like part.

[0033] The upwardly concave mating recesses that can be fitted downwardly onto the upper edge portion can be, for example, located in multiple locations spaced apart from each other along a straight line in the left-right direction, or they can be continuous in the left-right direction (in one location).

[0034] (4) When the stretcher-type mobility aid of the present invention is suspended across the upper parts of the first object and the second object as described above, the inclined upper surface portion can be configured to slope downwardly forward from the fore-aft position where the mating recess is located (preferably the fore-aft position where the mating recess is located) or a position close to the fore-aft position (for example, a fore-aft position within the fore-aft dimension of the mating recess, a fore-aft position within two-thirds of the fore-aft dimension of the mating recess, or a fore-aft position within one-half or one-third of the fore-aft dimension of the mating recess).

[0035] The inclined upper surface portion may be a flat surface, but is not necessarily limited to a flat surface.

[0036] Furthermore, when the stretcher-type mobility aid of the present invention is suspended across the upper parts of the first object and the second object as described above, the horizontal upper surface can be approximately horizontal (for example, horizontal enough that it can be slid easily relative to the upper surface as needed in either the forward or backward direction).

[0037] (5) The portion of the stretcher-type mobility aid of the present invention other than the inclined upper surface, when suspended as described above, may be, for example, in the form of a plate that is approximately along a horizontal plane or a plate that is approximately along a horizontal plane and reinforced at the bottom, and the inclined upper surface may be in the form of an inclined plate or an inclined plate that is reinforced at the bottom, but is not necessarily limited to these.

[0038] (6) The mating recess, which is located slightly rearward of the front end of the front surface of the stretcher-type mobility aid of the present invention, is fitted downwardly onto the upper edge portion that runs along a horizontal straight line in the left-right direction on the back side of the second object, and the rear portion is placed on the first object. This prevents the stretcher-type mobility aid from coming off or shifting from the first object or the second object when the stretcher with a subject on it is moved between the first object and the second object.

[0039] The mobility aid using stretchers suspended in this manner prevents the stretchers carrying the subject from falling between the first object located at the rear and the second object located at the front.

[0040] Therefore, the stretcher carrying the subject can be moved between the first and second objects safely by being temporarily placed on the upper surface of the stretcher-based mobility aid or by sliding the stretcher in the forward and backward directions relative to the upper surface as necessary. In addition, when moving forward to the second object (such as a mobile bathtub), the stretcher carrying the subject can be smoothly moved by sliding the stretcher on the inclined upper surface that slopes downwards forward.
