[0062] The technical solution of the present utility model will be described in detail below with reference to the embodiments and their accompanying drawings. It should be noted that in the drawings used to illustrate the embodiments, components with the same function are given the same reference numerals, and their repeated description can be omitted. In addition, in the embodiments of the present utility model, as Figure 1 shown, the description is made based on the front, back, left, right, and up and down defined with the user sitting on the bathing assistance tool 100 as the reference. In addition, the helper refers to a person who cleans the body of the user sitting on the bathing assistance tool 100.

[0063] As Figure 1 and Figure 2 shown, the bathing assistance tool 100 in this embodiment includes a frame 10, an upper body cushion 20, and a lower body seat cushion 30. The bathing assistance tool 100 in this embodiment is described based on the form of being installed on the leg frame 40. However, since the leg frame 40 is an additional structure, the bathing assistance tool 100 can also be used alone, and the usage state is as Figure 3 shown. Figure 1 and Figure 2 shown, when the bathing assistance tool 100 is in use, the front-back direction dimension (longitudinal dimension) of the leg frame 40 is 706 mm, and the left-right direction dimension (width dimension) is 450 mm. By adopting such a planar dimension, even in a general household bathroom in Japan (with an internal dimension of 1600 mm × 1200 mm), it can be installed in the bathroom in a sufficient state, and the caregiver can enter the bathroom together to clean the body of the user sitting on the bathing assistance tool 100.

[0064] As Figure 4 shown, the frame 10 has a main frame 12, a back frame 14 attached to the main frame 12, and a below-knee frame 16. The frame 10 in this embodiment is formed into a so-called pipe frame shape made of aluminum alloy. However, the material of the frame 10 is not limited to aluminum alloy, and other known materials represented by synthetic resin can be used. On the bottom surface of the main frame 12, grounding pieces (not shown in the figure) made of synthetic rubber or the like for anti-slip and preventing scratching of the ground are scattered and installed at the contact part with the installation surface.

[0065] The main frame 12 is composed of two first components 12A extending in the front-rear direction and arranged in parallel in the left-right direction, and three second components 12B connecting the two first components 12A. The first component 12A and the second component 12B surround to form a seat surrounding portion IJ1, and a part of the main frame 12 has a trapezoidal frame shape. The two first components 12A are bent upward and forward at the middle part in the length direction. At this bent portion, upright portions 13 extending upward in the axial direction of the first component 12A are respectively erected.

[0066] In addition, at the middle position of the inclined portion of the first component 12A, a grounding body 12D for grounding with the installation surface is installed by a known method such as welding. The grounding body 12D in this embodiment is formed as a flat ring body, which has a straight portion arranged parallel to the second component 12B on the side of the lower knee frame 16 in the height direction, and a semi-circular arc portion connecting the right end and the left end of these two components in the vertical direction. In addition, a grounding piece (not shown) is provided on the bottom surface of the grounding body 12D. By adopting such a grounding body 12D, the caregiver or the ground will not be damaged. The semi-circular arc portion of the grounding body 12D in this embodiment can also be used as a holding portion for the user. The grounding piece (not shown) can also be installed on the semi-circular arc portion of the grounding body 12D. By providing such a holding portion, when the user sits on the bath assisting appliance 100, the user can maintain the posture with confidence and can suppress the shaking of the body when washing the body.

[0067] At the middle height position of the upright portion 13, a grip 13A protruding in a direction crossing the axial direction of the upright portion 13 (toward the right in the left upright portion 13 and toward the left in the right upright portion 13) is provided. By means of this grip 13A, the upper limit of the upright angle of the back frame 14 relative to the main frame 12 (installation surface) described later is restricted. The required length portions at both ends of the rearmost second component 12B protrude outward from the two first components 12A, and this protruding portion bends toward the inner plane area of the main frame 12, and the corner portion on the rear side of the main frame 12 is formed in an arc shape. Protective covers 12C made of synthetic rubber or the like are installed at both ends of the second component 12B. By adopting such a main frame 12, the risk of injury to the user and the helper for cleaning the user's body and the risk of damaging the ground are reduced.

[0068] The back frame 14 is rotatably attached to the upright portion 13 of the main frame 12. The back frame 14 has a first back frame 14A that is inverted U-shaped in plan view and a plurality of second back frames 14B that are erected inside the first back frame 14A. A back loop portion IJ2 serving as an enclosing portion is formed by the first back frame 14A and the second back frames 14B, and a part of the back frame 14 is in the shape of a trapezoidal frame. The first back frame 14A has two straight pipe sections 14Aa and a U-shaped pipe section 14Ab that can be pulled out (inserted and removed) from the straight pipe sections 14Aa. In the straight portion of the U-shaped pipe section 14Ab, a plurality of through holes 14C for length adjustment are formed at required positions in the length direction (telescopic direction) (refer to Figure 5 ), and a telescopic mechanism portion is formed that can adjust and fix the protruding length (pull-out length) of the U-shaped pipe section 14Ab relative to the straight pipe sections 14Aa by means of a length adjustment stopper 50. Therefore, the back frame 14 can be telescoped (height adjustable), and the arrangement position (height position) of the head support pad 22 relative to the main frame 12 (back pad 24) can be adjusted. That is, in the present embodiment, the head frame serving as the head is constituted by the U-shaped pipe section 14Ab and a part of the second back frame 14B. In addition, between the back frame 14 and the main frame 12 of the present embodiment, a back angle adjustment frame 17 for adjusting the standing angle of the back frame 14 relative to the main frame 12 (mounting surface) is disposed.

[0069] The length adjustment stopper 50 is assembled to an arcuate portion 52 on the outer peripheral surface of the back frame 14 and a rod-shaped stopper 54 disposed inside the arcuate portion 52 and insertable into the through hole 14C of the U-shaped pipe section 14Ab has a ring 56 attached to the outer surface of the arcuate portion 52. The stopper 54 preferably penetrates radially through the frame body in the mounting portion. A belt 60 for fixing the user is detachably engaged with the ring 56 (refer to Figure 6 ). The length adjustment stopper 50 further includes a connecting portion between the main frame 12 and the sub-knee frame 16 and is disposed in the sub-knee frame 16 and is provided for at least one of the length adjustment portion and the belt engagement portion.

[0070] As Figure 1 and Figure 2 shown, the back angle adjustment frame 17 is constituted by a first cylindrical portion 17A, a fixing screw 17B, and a second cylindrical portion 17C as a telescopic mechanism portion. The first cylindrical portion 17A is rotatably connected to the second member 12B of the main frame 12. The fixing screw 17B is screwed into a through hole (not shown) that penetrates radially through the first cylindrical portion 17A. The second cylindrical portion 17C is rotatably connected to the second back frame 14B at the position closest to the main frame 12 and is received so as to protrude from the internal space of the first cylindrical portion 17A, and a plurality of position adjustment holes 17D are provided at required intervals in the length direction. The position of the position adjustment hole 17D is adjusted by the fixing screw 17B. The standing angle of the back frame 14 relative to the main frame 12 (mounting surface) can be adjusted in multiple stages (seeFigure 7 )。In the back frame 14, a shift lever 13A is disposed on the upright portion 13 of the frame 12. The shift lever 13A limits the upper limit of the upright angle, and the first cylindrical portion 17A and the second cylindrical portion 17C do not come off.

[0071] As Figure 4 shown, the below-knee frame 16 has a first below-knee frame 16A that is inverted U-shaped in plan view and a second below-knee frame 16B that is installed inside the first below-knee frame 16A. In the below-knee frame 16, a below-knee loop portion IJ3 serving as an enclosing portion is formed by the first below-knee frame 16A and the second below-knee frame 16B, and a part of the below-knee frame 16 forms a trapezoidal frame shape. The first below-knee frame 16A is insertable into and removable from the main frame 12, and a plurality of second through holes 16C for positioning are formed along the length direction (the telescopic direction) in the straight portion of the first below-knee frame 16A (refer to Figure 5 )

[0072] . The straight portion of the first below-knee frame 16A is a telescopic mechanism portion in which the protruding length (the leading-out length) from the front end portion of the first member 12A of the main frame 12 can be adjusted and fixed by a length adjustment stopper 50. Thereby, the arrangement position of the leg support pad 34 relative to the main frame 12 (the seat cushion 32) can be adjusted.

[0073] As Figure 1 and Figure 8 shown, the upper body cushion 20 is provided at a position with a gap S (in a separated state) from the lower body seat cushion 30. In this embodiment, the upper body cushion 20 and the lower body seat cushion 30 are formed of a resin in a foam state that is rich in flexibility, such as foamed polyurethane, foamed EVA (ethylene vinyl acetate copolymer), silicone, and latex. A material having a measured value of the Asker rubber hardness meter between C20 and C60 is more suitable here, and a material with a hardness between C22 and C35 makes the contact with the body softer and the usability better. In addition, the upper body cushion 20 and the lower body seat cushion 30 preferably have a waterproof coating, and the waterproof coating more preferably contains an antibacterial agent. Through this coating, the surfaces of the upper body cushion 20 and the lower body seat cushion 30 are smoother. The measured values of the upper body cushion 20 and the lower body seat cushion 30 measured with an Asker rubber hardness meter are preferably between C20 and C60, and among them, C22 to C35 makes the contact with the body softer, so the use feeling is better.

[0074] In addition, as the antibacterial agent, antiviral and antibacterial special compounds derived from ammonium represented by quaternary ammonium salts, titanium oxide and titanium compounds, silver and silver compounds, copper and copper compounds, natural polymer materials represented by chitosan, and lime-containing alkaline substances can be cited. The upper body cushion 20 and the lower body seat cushion 30 have a waterproof coating containing such an antibacterial agent, which is easy to clean after use, dries quickly, and further prevents the growth of bacteria. Therefore, the upper body cushion 20, the lower body seat cushion 30, and the frame 10 hardly get moldy and can be used hygienically for a long time.

[0075] The upper body cushion 20 of the present embodiment has a head support cushion 22 that supports the user's head and a back cushion 24 that supports the user's back. On the rear (back) surface of the head support cushion 22 of the present embodiment, a first fitting convex portion 22A that is concavo-convexly fitted to the uppermost position back ring portion IJ2 formed on the back frame 14 is formed. The protruding height dimension of the first fitting convex portion 22A is preferably larger than the outer diameter dimensions of the first back frame 14A and the second back frame 14B that form the back ring portion IJ2 in order to reliably mount the head support cushion 22 to the back ring portion IJ2. In addition, on the rear (back) surface of the back cushion 24, a second fitting convex portion 24A that is concavo-convexly fitted to the lowermost back ring portion IJ2 of the back frame 14 is formed. In order to reliably mount the back cushion 24 to the back ring portion IJ2, the protruding height dimension of the second fitting convex portion 24A is much larger than the outer diameter dimensions of the first back frame 14A and the second back frame 14B that form the back ring portion IJ2.

[0076] The head support cushion 22 and the back cushion 24 formed as described above are detachably mounted on the back ring portion IJ2 of the back frame 14 with a predetermined gap S in the height direction (in a separated state). In addition, the head support cushion 22 and the back cushion 24 in the present embodiment can be sufficiently elastically deformed by the force of the hands of a helper or the like, so they can be mounted on the back ring portion IJ2 without using tools. In addition, the head support cushion 22 and the back cushion 24 after being mounted on the back ring portion IJ2 are in a state of biting with the back ring portion IJ2 due to the restoration of elastic deformation, so they can be prevented from accidentally falling off the back ring portion IJ2. In addition, on the lower end edge of the second fitting convex portion 24A having a relatively long outer peripheral edge length in contact with the back ring portion IJ2, a back outer peripheral edge recess 24Aa is formed. By forming a gap between the back outer peripheral edge recess 24Aa and the second back frame 14B, a finger can be inserted into the gap, and the back cushion 24 can be easily attached to and detached from the back ring portion IJ2.

[0077] As Figure 2 and Figure 9As shown, on the back (rear surface) of the outer surface of the backrest 24, the display of "up" and "down" is performed as the fitting direction display portion, and this fitting direction display portion indicates the up and down directions of the backrest 24 when the second fitting convex portion 24A is fitted into the back ring portion IJ2 in a concave-convex manner. The fitting direction display portion of the present embodiment is formed by arranging recesses on the rear surface (back surface) of the backrest 24. Therefore, unlike the printed fitting direction display portion, the fitting direction display portion will not disappear even after long-term use.

[0078] In addition, on the front surface (front side) of the backrest 24, which is the contact surface with the user's back, a back recess 24B is formed along the central axis in the width direction of the back frame 14 (see Figure 3 etc.). The recessed portion of the back recess 24B should be at least 3 mm lower than the flat portion on the surface of the backrest 24 and reach the lower end edge position of the backrest 24. That is, the back recess 24B opens in the gap S between the lower end portion of the backrest 24 and the seat cushion 32 disposed adjacent to the backrest 24 at a position below the backrest 24. Therefore, during use, a gap is formed between the user's back and the backrest 24, and drainage can be performed from the user's waist to below the bathing assistance tool 100. In addition, regarding the step between the flat portion on the surface of the backrest 24 and the back recess 24B, from the flat portion side on the surface of the backrest 24 to the back recess 24B, the flat portion side on the surface of the backrest 24 is formed in an upwardly convex R shape, and the back recess 24B side is formed in a downwardly convex R shape. Therefore, even if there is a height difference on the front surface of the backrest 24, no marks will be left on the user's back.

[0079] In addition, on the lower part of the front surface (front side) of the backrest 24 (the part corresponding to the user's side abdomen), back protrusions 24C extending forward along the user's side abdomen are arranged from the sides (right and left) of the backrest 24. With these back protrusions 24C, the user's arms can be in a state where they can freely move up and down, maintaining the user's initial sitting state. In addition, even if the user lacks the physical strength to maintain the initial sitting position, it is easy to maintain the initial sitting position through the back protrusions 24C, and the caregiver can safely and easily wash the user's body.

[0080] The lower body seat cushion 30 in the present embodiment has a seat cushion 32 (seat portion) that supports the buttocks corresponding to the user's buttocks and a leg support cushion 34 that supports the legs corresponding to the user's legs (below the knees). The seat cushion 32 and the leg support cushion 34 are separately arranged (see Figure 8)。A third fitting convex portion 32A that engages with the seat ring portion IJ1 of the main frame 12 in a concave and convex manner is formed on the lower surface (bottom surface) of the outer surface of the seat cushion 32. The protruding height dimension of the third fitting convex portion (32A) is such that the first component 12A of the seat ring portion IJ1 is formed to reliably mount the seat cushion 32 on the seat ring portion IJ1, and is preferably larger than the outer diameter dimension of the second component 12B. Also, on the lower surface (bottom surface) of the outer surface of the leg support cushion 34, a fourth fitting convex portion 34A is formed by engaging with the lower knee ring portion IJ3 of the lower knee frame 16 in a concave and convex manner. The protruding height dimension of the fourth fitting convex portion 34A is such that in order to reliably mount the leg support cushion 34 on the lower knee ring portion IJ3, it is preferably larger than the outer diameter dimensions of the first lower knee frame 16A and the second lower knee frame 16B of the lower knee frame 16 on which the lower knee ring portion IJ3 is formed.

[0081] The seat cushion 32 and the leg support cushion 34 formed as described above are detachably mounted on the seat ring portion IJ1 of the main frame 12 and the lower knee ring portion IJ3 of the lower knee frame 16 in the front-rear direction with a predetermined gap S therebetween (in a separated state). In addition, the seat cushion 32 and the leg support cushion 34 in this embodiment can be sufficiently elastically deformed by the force of a helper's hand, and thus can be mounted on the seat ring portion IJ1 and the lower knee ring portion IJ3 without using tools. Further, after the seat cushion 32 and the leg support cushion 34 are mounted on the seat ring portion IJ1 and the lower knee ring portion IJ3, they enter a state of engaging with the seat ring portion IJ1 and the lower knee ring portion IJ3 by restoring elastic deformation. Therefore, it is possible to prevent the seat cushion 32 and the leg support cushion 34 from falling off the unexpected seat ring portion IJ1 and the lower knee ring portion IJ3.

[0082] On the left and right end edges of the third fitting convex portion 32A having a relatively long outer peripheral edge length in contact with the seat ring portion IJ1, seat portion outer peripheral edge recesses 32Aa are formed. By the seat portion outer peripheral edge recesses 32Aa, a gap is formed between the seat ring portions IJ1, and fingers can enter the gap, and the seat cushion 32 can be easily disassembled and assembled to the seat ring portion IJ1. When the third fitting convex portion 32A engages with the seat ring portion IJ1 in a concave and convex manner, "front" and "rear" are displayed on the lower surface (bottom surface) of the seat cushion 32 as a fitting direction display portion to indicate the front-rear direction of the seat cushion 32. The fitting direction display portion of this embodiment is formed by providing a recess on the lower surface (bottom surface) of the seat cushion 32, and thus is different from a printed fitting direction display portion. Even after long-term use, the fitting direction display portion will not disappear.

[0083] On the upper surface of the seat cushion 32 which is the contact surface with the user's buttocks in this embodiment, a seat recess 32B is formed along the width direction central axis of the main frame 12 and the lower knee frame 16 (see Figure 3The seat recess 32B is at least 3 mm lower than the flat part of the seat cushion 32 and reaches the rear end edge position of the seat cushion 32. That is, the seat recess 32B opens in the gap S between the rear end portion of the seat cushion 32 and the seat cushion 32 disposed adjacent to the seat cushion 32 at the upper position of the seat cushion 32. In addition, the bottom surface height position of the seat recess 32B forms an inclined surface that gradually decreases on the back pad 24 side, and the seat cushion 32 has a height difference in the front-to-back direction. That is, when in use, a gap is formed between the user's buttocks and the seat cushion 32, and water can be drained from the crack part of the user's buttocks to the bottom of the bathing aid tool 100. Regarding the step between the flat upper surface of the seat cushion 32 and the seat recess 32B, between the flat upper surface side of the seat cushion 32 and the seat recess 32B, the flat upper surface side of the seat cushion 32 is formed into an R-shape convex upward, and the seat recess 32B side is formed into an R-shape convex downward. Therefore, even if the upper surface of the seat cushion 32 has a height difference, it will not leave a mark on the user's buttocks.

[0084] In addition, seat protrusions 32C are arranged on the sides (left and right) of the upper surface of the seat cushion 32. The seat protrusions 32C are formed on a curved inclined surface that stretches upward from each side of the flat upper surface of the seat cushion 32 along the outer sides of the user's left thigh and right thigh. Even on the upper surface of the seat cushion 32, a convex portion not shown is formed at a position corresponding to the perineum of the user. The seat cushion 32 is composed of these seat protrusions 32C and the convex portion and can be supported in a state of close contact with the user's buttocks. Therefore, even if the physical strength for maintaining the user's initial sitting state is insufficient, it is easy to maintain the user's initial sitting state on the seat cushion 32, and the user's body can be safely and easily cleaned by a helper.

[0085] A fourth engaging convex portion 34A (see FIG. 1 ) is formed on the lower surface (bottom surface) of the leg support pad 34, and the fourth engaging convex portion 34A is formed on the lower surface (bottom surface) of the lower knee frame 16. Figure 8 , Figure 9 ). The protruding height dimension of the fourth interlocking protrusion 34A is preferably larger than the outer diameter dimension of the first and second knee frames 16A and 16B formed with the knee loop portion IJ3. The upper surface of the leg support pad 34 is formed as a curved surface, wherein the left and right end portions are parabolically tilted upward relative to the central portion, and the front and rear ends are respectively inclined downward relative to the central portion in a parabolic shape. The leg support pad 34 is arranged on the upper front side of the seat cushion 32, and can appropriately support the calf from the user's knee back. Therefore, it is also advantageous in that the user's legs are not stiffened and the user's legs are not disturbed during bathing.

[0086] The leg frame 40 of the present embodiment includes a first rectangular frame body 42, a second rectangular frame body 44, an over-opening prevention belt 46, and a frame fixing member 48 (see Figure 4)。Both ends of the lower short side 42A of the first rectangular frame body 42 protrude from the long side 42B, and a grounding cap 43 is installed at the protruding part of the lower short side 42A. The second rectangular frame body 44 is also formed in the same shape as the first rectangular frame body 42. The outer width dimension of the second rectangular frame body 44 is formed to be approximately equal to the inner width dimension of the first rectangular frame body 42, and the second rectangular frame body 44 is arranged inside the first rectangular frame body 42 in an X shape when viewed from the side. The first rectangular frame body 42 and the second rectangular frame body 44 are rotatably connected by a rotating shaft 45 at the middle position in the length direction of the long side 42B and the second long side 44B.

[0087] An anti-overopening belt 46 for preventing the first rectangular frame body 42 and the second rectangular frame body 44 from overopening is installed on the upper short side 42C of the first rectangular frame body 42 and the second upper short side 44C of the second rectangular frame body 44. The anti-overopening belt 46 in this embodiment is formed of a material that hardly bends due to its own weight but can be elastically deformed into a bent state by folding the leg frame 40. However, the material of the anti-overopening belt 46 is not particularly limited. The anti-overopening belt 46 in this embodiment is installed by engaging the engaging portions 46A at both ends in the length direction with the upper short side 42C of the first rectangular frame body 42 and the second upper short side 44C of the second rectangular frame body 44. Further, by passing bolts (not shown) through the anti-overopening belt 46 and the upper short side 42C of the first rectangular frame body 42 and the second upper short side 44C of the second rectangular frame body 44 respectively and tightening them with nuts (not shown), the anti-overopening belt 46 can be firmly fixed to the leg frame 40.

[0088] In addition, on the upper short side 42C of the first rectangular frame body 42 and the second upper short side 44C of the second rectangular frame body 44, frame fixing members 48 for loading and unloading the frame 10 are arranged. The frame fixing members 48 are integrated in a state where the openings of the semi-circular arcs formed by dividing the cylinder in the diameter direction are facing outward, and through threaded holes are formed in the integrated part between the semi-circular arcs. The frame fixing members 48 are fixed by fitting the opening of one semi-circular arc with the upper short side 42C of the first rectangular frame body 42 and the second upper short side 44C of the second rectangular frame body 44, inserting bolts (not shown) into the through screw holes, and tightening them with nuts (not shown).

[0089] In this embodiment, the inner width dimension W1 of the two frame fixing members 48 installed on the first rectangular frame body 42 is equal to or greater than the outer width dimension W2 of the two frame fixing members 48 attached to the second rectangular frame body 44. Therefore, as Figure 10 shown, the leg frame 40 can be folded without interfering with the respective frame fixing members 48. In addition, as Figure 10As shown, in the bath assisting tool 100 of this embodiment, the back frame 14 is folded in a substantially straight line with the main frame 12 (the back frame 14 is substantially parallel to the main frame 12). While folding, in a state of being connected to the frame fixing member 48 on the upper short side 42C side of the first rectangular frame body 42, the leg frame 40 can be folded into an I-shaped configuration. Thus, the occupied space of the bath assisting tool 100 when not in use can be significantly reduced relative to the occupied space of the bath assisting tool 100 when in use. Therefore, the bath assisting tool 100 can be folded compactly and kept integrally, and the used bath assisting tool 100 can also be stored in the bathroom.
