SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem

However, for example, in toilets in hospitals and nursing homes, disabled persons and elderly persons (hereinafter, referred to as "care-givers") who use toilet stools enter a space in front of the toilet stools from the lateral direction while sitting on a wheelchair. In this case, when the care-receiver sitting in the wheelchair rises from the wheelchair in the front space, the back side (hip side) turns to the toilet bowl, and then the care-receiver sits on the toilet bowl. When moving from the toilet stool to the wheelchair, the seat is turned to the wheelchair on the back side after standing up from the toilet stool, and then is seated on the wheelchair, in contrast to the above.

As described above, when a care recipient moves between the toilet and the wheelchair, it is necessary to perform a turning operation in a standing posture in the space in front of the toilet. Further, there are persons who are difficult to maintain a standing posture by themselves, persons who are difficult to turn around, and persons who are difficult to put on and take off clothes and underwear. In hospitals and nursing homes, particularly, when a care-receiver is difficult to maintain a standing posture by himself/herself, it is difficult for 1 caregiver to support the care-receiver in the standing posture to assist turning around and to put on/off clothes. Therefore, the burden on a caregiver who supports a standing care recipient by 1 caregiver while assisting the turning-around operation by another caregiver or putting on and taking off the clothes and underwear of the care recipient is large, particularly, the caregiver who holds the care recipient in a standing position.

In addition to the above, there are various cases in which nursing (assistance) by a caregiver is required to maintain the standing posture of a care recipient. For example, the care-receiver may move between a bed and a wheelchair, or the care-receiver may put on or off the clothes of the care-receiver in a standing position in a dressing room.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an armrest device that can maintain a standing posture by a care-receiver himself/herself.

Means for solving the problems

In order to achieve the above object, in the present invention, the following solution is adopted.

That is, the armrest apparatus has a pair of right and left vertical grips extending in the vertical direction, respectively, for allowing a care recipient to maintain a standing posture, the vertical grips are formed in a curved shape so as to project toward the front side, the interval between the vertical grips is set to be smaller than the shoulder width of the care recipient, and the pair of vertical grips supports the front surface portion of the upper body of the care recipient in the standing posture.

The second aspect is the armrest device according to the first aspect, wherein a receiving portion for supporting a front surface portion of an upper body of the care recipient is provided between the pair of left and right vertical grips. In this case, too, the care recipient is preferably supported by the support unit, so that more stable support can be obtained.

A third aspect of the present invention is the armrest device according to the first aspect, wherein an upper coupling portion is provided to couple upper end portions of the pair of left and right grip bars. A fourth aspect of the present invention is the armrest apparatus according to the second aspect, wherein an upper coupling portion is provided to couple upper end portions of the pair of left and right grip bars. In this case, it is preferable to increase the strength (rigidity) of the armrest device.

A fifth aspect of the present invention is the armrest device according to the third aspect, wherein the upper coupling portion includes: a pair of left and right lateral parts extending from the upper end parts of the pair of left and right longitudinal grips to the inner side; and a central connecting portion extending substantially horizontally and connecting lower end portions of the pair of left and right side portions to each other. In this case, the position of the center connecting portion is set to a position retracted to the back side considerably more than the pair of left and right vertical grips. That is, a large escape space toward the inside is formed between the pair of right and left longitudinal grips and at the upper portion thereof. Therefore, the care-receiver leaning against the left and right pair of longitudinal holding rods can make the chin in the avoiding space, and can obtain a posture of tilting more forwards. This makes it preferable for the carereceiver to maintain the standing posture more reliably. Further, it is preferable for the care-receiver leaning on the pair of left and right grip bars to have a front part near the face thereof opened as a space for escape, so that the care-receiver does not feel a sense of pressure.

A sixth aspect of the present invention is the armrest device according to any one of the first to fifth aspects, wherein a lower connecting portion is provided to connect lower end portions of the pair of left and right vertical grips. In this case, the strength (rigidity) of the armrest apparatus is improved. In particular, in the case of the above-described upper coupling portion, the armrest apparatus has a structure in which the pair of left and right vertical grips, the upper coupling portion, and the lower coupling portion are annularly closed, and the strength (rigidity) thereof can be significantly improved.

A seventh aspect of the present invention is the armrest device according to any one of the first to fifth aspects, wherein a frame portion for supporting the pair of left and right longitudinal grips on a floor surface or a wall surface is provided. In this case, the armrest device can be supported in advance on the floor surface or the wall surface via the frame portion.

A sixth aspect of the present invention is the armrest apparatus according to any one of the first to fifth aspects, wherein the pair of left and right vertical grips are provided on a front side of the toilet bowl. In this case, the following effects (1) to (6) can be obtained with respect to the posture change between the standing posture and the seating posture of the toilet bowl. In particular, although the toilet bowl is frequently used and the worker puts on and off clothes and underwear each time the care-receiver is in a standing posture is a heavy burden on the care-giver, it is preferable to greatly reduce the burden on the care-giver. Further, when the wheelchair enters the vicinity of the toilet pan, the three positions of the sitting position, the standing position, and the sitting position in the toilet pan in the wheelchair are changed in a reciprocating manner.

A ninth aspect is the armrest apparatus according to the eighth aspect, wherein the pair of left and right vertical grip bars are inclined so as to face the toilet bowl side, respectively, in a plan view from above. In this case, the caregiver seated in the toilet can easily grip the longitudinal grip at the near side. When the care recipient stands up from the wheelchair and leans his/her upper body against the vertical grip, the care recipient naturally turns his/her back toward the toilet bowl.

A tenth aspect of the present invention is the armrest device according to the second aspect, wherein at least a surface of the receiving portion facing the care recipient is configured as a cushion portion. In this case, it is preferable that the care recipient does not feel local pain when the care recipient leans against the receiving portion.

According to the above solution, the following effects are achieved.

That is, (1) the front surface portion of the upper body of the care recipient in the standing posture is supported by the pair of right and left vertical grips, and the standing posture of the care recipient can be stably maintained. In this case, the care-receiver is in a posture leaning against the pair of left and right grips in the forward tilted state, and therefore, the care-receiver can reliably maintain the standing posture without slipping off the pair of left and right grips.

(2) Since the pair of left and right vertical grips is provided, it is also preferable that the care-receiver lean on one of the left and right vertical grips to make it easy to turn the care-receiver toward the one vertical grip, and turn the care-receiver while keeping the standing posture.

(3) Since the pair of vertical grips extending in the vertical direction are provided on the left and right sides, a care recipient approaching the vertical grips can grip the vertical grips at an appropriate position selected from a wide range in the vertical direction and the horizontal direction, and can easily stand up and sit down while gripping the vertical grips. Further, the armrest apparatus is not limited to the approaching direction with respect to the armrest apparatus, and can approach the armrest apparatus from a wide direction.

(4) Since the lower end portions of the pair of right and left vertical grips are located on the inner side, it is preferable to sufficiently secure the underfoot space of the care recipient. This is extremely preferable in terms of securing a space for putting on and off clothes of a care-receiver held in a standing posture and for performing manual work by a caregiver who puts on and off the clothes.

(5) Since the care-receiver himself or herself maintains the standing posture by the armrest device, a caregiver for maintaining the standing posture is not necessary, and it is extremely preferable in terms of reducing the burden of nursing care. Further, since the care-receiver leans forward in the standing posture, the clothes can be easily put on and taken off, and the burden on the care-receiver can be reduced.

(6) The self-standing care-receiver can put on and take off clothes by the care-receiver himself by using free hands or one hand while leaning against the pair of left and right longitudinal grips.

The utility model has the following effects.

According to the utility model, the person to be nursed can keep standing by himself.

Detailed Description

Fig. 1 to 11 show a first embodiment of the present invention. In the present embodiment, the armrest device is disposed on the front side of the toilet bowl, and the care-receiver is used in a wheelchair with respect to the toilet bowl.

Fig. 1 shows an example of a wheelchair-entry toilet (toilet: toil room, toilet room: toil booth). In the attached drawings, 1 is a toilet bowl, and 10 is a wheelchair. The toilet 1 is separated from the rear by a rear wall 2, and the toilet 1 is separated from the left by a lateral wall 3. A back support member 4 is disposed on the toilet bowl 1, and the back support member 4 is fixed to the rear wall surface 2 via a bracket 5.

The wheelchair 2 enters from the lateral direction toward a front space K of the toilet 1 (a space on the left side of the toilet 1 in fig. 1). The direction of entry of the wheelchair 2 is shown by arrow Y in the figure. The entering direction Y of the wheelchair 10 is a direction substantially perpendicular to the lateral wall surface 3 in the embodiment. The direction opposite to the direction indicated by the arrow Y is the direction of the entrance and exit of the toilet.

In the front space K, an armrest device 20 is disposed on the left side (the lateral wall surface 3 side) of the toilet bowl 1. The armrest device 20 includes a first grip 21 and a second grip 22, which are vertically paired right and left. The first longitudinal grip 21 is located on the side closer to the bowl 1 and the second longitudinal grip 22 is located on the side farther from the bowl 1. The upper ends of the vertical grips 21, 22 are connected to each other by an upper connecting portion 23 extending substantially horizontally. Lower ends of the vertical grips 21 and 22 are connected to each other by a lower connecting portion 24 extending substantially horizontally.

The pair of left and right vertical grips 21 and 22, the upper coupling portion 23, and the lower coupling portion 24 form a square shape (closed ring shape), and the square portion is fixed to the lateral wall surface 3 via the frame portion 30.

The frame portion 30 includes a holding portion 31 extending in the vertical direction, a base portion 32 fixed to the lateral wall surface 3, and a bracket portion 33 connecting the holding portion 31 and the base portion 32. The base portion 32 is fixed to the rear wall surface 2 by a fixing member 34. The bracket portion 33 extends substantially in the horizontal direction in the present embodiment. The bracket portion 33 includes a cylindrical body portion 33a extending horizontally, a plate-like protruding portion 33b integrally formed (for example, welded) on the front end portion side of the body portion 33a, and a mounting portion 33c provided on the front end portion of the protruding portion 33 b.

The holding portion 31 connects substantially intermediate portions of the upper connecting portion 23 and the lower connecting portion 24 to each other. The holding portion 31, the bracket portion 33, and the upper and lower coupling portions 23 and 24 constitute an intermediate coupling member for coupling the pair of left and right vertical grips 21 and 22 to the base portion 32.

A gasket portion 40 as a receiving portion is fixed to the holding portion 31 via the mounting portion 35. The spacer portion 40 is located between the pair of left and right grip bars 21 and 22 and between the upper coupling portion 23 and the lower coupling portion 24.

Here, each of the vertical grip bars 21, 22 is formed in a curved shape in a substantially circular arc shape so as to project toward the near side (the side away from the lateral wall surface 3), and projects toward the near side. The following settings are set: the amount of protrusion of the first longitudinal grip 22 to the near side on the side farther from the toilet bowl 1 is larger than the amount of protrusion (amount of protrusion) of the first longitudinal grip 21 to the near side on the side closer to the toilet bowl 1. Further, in the embodiment, the first longitudinal grip 21 and the second longitudinal grip 22 are differently bent, and in the embodiment, the radius of curvature of the first longitudinal grip 21 is set to about 800mm and the radius of curvature of the second longitudinal grip 22 is set to about 400 mm.

The extending direction of each of the vertical grips 21, 22 is inclined with respect to the lateral wall surface 3 in a plan view seen from above. The inclination angle with respect to the lateral wall surface 3 is set to: the inclination angle of the first longitudinal grip 21 is smaller than that of the second longitudinal grip 22 in the plan view. When the extending direction of each of the vertical grip bars 21 and 22 is regarded as being inclined with respect to the entering direction Y of the wheelchair 10, the inclination angle of the first vertical grip bar 21 is set to be smaller than the inclination angle of the second vertical grip bar 22. Further, by loosening the mounting portion 33c of the bracket portion 33 supporting the holding portion 31, the holder portion 31 can be swung about the holding portion 31, and the inclination angle of the grip 21 or 22 with respect to the lateral wall surface 3 can be adjusted.

The holding portion 31 is located further to the inside than the pair of left and right vertical grips 21, 22. The pad portion 40 attached to the holding portion 31 is located slightly inward of the pair of left and right grip bars 21, 22.

Like the longitudinal grips 21, 22, the pad portion 40 is curved in a convex manner toward the proximal side. The inclination direction thereof in plan view is inclined at an angle of approximately 45 degrees with respect to the lateral wall surface 3. The pad portion 40 (the surface closest to the front side thereof) is located slightly further inward (toward the lateral wall surface 3) than the grip bars 21, 22. The space between the pair of left and right grip members 21 and 22 is filled with the spacer portion 40, but gaps are formed between the first grip member 21 and the second grip member 22 on the left and right of the spacer portion 40 to allow a fingertip to be inserted with a margin.

As described above, since the pair of left and right grip bars 21, 22 are projected in different directions from each other in a plan view from above, the distance between the portions of the pair of left and right grip bars 21, 22 above the portion projected most toward the front side becomes narrower toward the upper side due to the difference in the projecting direction. Accordingly, when the care recipient P leans against the pair of left and right grip bars 21, 22 obliquely, the chest of the care recipient P is pushed between the pair of left and right grip bars 21, 22 (the abdomen is also in the above-described state depending on the physique and the oblique leaning manner of the care recipient), and it is preferable that the front surface portion of the upper body of the care recipient P is reliably supported.

Here, the maximum width L (see fig. 2) of the pair of left and right longitudinal grips 21 and 22 is set to be the same as or slightly smaller than the shoulder width (more specifically, the chest width) of the care recipient. The height position of (the upper surface of) the upper connecting portion 23 from the floor surface is set to be slightly lower than the chin of the care recipient in the standing posture. In the embodiment, it is assumed that a care recipient having a small body size is provided with the maximum width L, the height position of the upper coupling portion 23 from the floor surface, and the vertical length (linear length) between the upper surface of the upper coupling portion 23 and the lower surface of the lower coupling portion 24. In addition, even when the setting is made in accordance with the short figure, there is no problem for the carereceiver with a large figure.

Next, an example of a method of moving the toilet 1 and the wheelchair 10 will be described with reference to fig. 1, 6 to 11. In fig. 1, the care recipient P when seated in the wheelchair 10 is shown in solid lines, and in fig. 11, the care recipient P when seated in the toilet bowl 1 is shown in solid lines. In the following description, as the care recipient P, both the case where both hands are free and the case where the right hand is not free are described, and fig. 6 to 10 correspond to the case where both hands are free.

First, the care recipient enters the front space K of the toilet bowl 1 in a state of being seated on the wheelchair 10 (a state shown in fig. 1). Then, the care recipient P on the wheelchair puts his or her hand forward and holds the first grip 21 with his or her left hand and the second grip 22 with his or her right hand when both hands are free (see fig. 6 and 7). In the case where the right hand is not free, the first longitudinal grip 21 is held only with the left hand. The care recipient P can select an appropriate height position according to the physique of the person who holds the vertical grip 21 or 22.

The care recipient P stands up from the wheelchair 10 with the grip bars 21 and 22 (or only 21) held, and leans his/her upper body against the grip bars 21 and 22 (see fig. 8). At this time, the caregiver P turns naturally so that the back of the caregiver P faces the toilet bowl 1. The chest (particularly, pectoralis major) in the front portion of the upper body of the care recipient P is supported by the pair of left and right grip bars 21, 22, and the center portion of the chest is supported by the spacer portion 40. Depending on the physical constitution of the care recipient P, the abdomen may be supported by the grip bars 21 and 22 and the pad 40.

The portions of the pair of left and right vertical grips 21 and 22 above the portions projecting most forward are located further inward as they face upward. Thus, the care-receiver in the standing position is supported in a state of leaning forward with respect to the longitudinal grips 21 and 22, and is reliably supported without slipping off the longitudinal grips 21 and 22. Further, the portions of the vertical grip bars 21 and 22 that come into contact with the care recipient P can avoid the clavicle that is likely to feel pain (can be supported below the clavicle).

In addition, in a state where the care recipient P is stably supported by the pair of left and right grip bars 21 and 22 and the pad 40, the caregiver can take off the pants and underwear of the care recipient P and prepare for defecation, and care for keeping a standing posture is not necessary (one caregiver may be used). In addition, when the care recipient can stand alone, the care recipient can put on and take off clothes by himself/herself using both hands or one hand in a state of leaning against the pair of left and right vertical grips 21 and 22.

From the state where the care recipient P takes off the pants and underwear, the body is turned back so that the back faces the toilet bowl 1 side while holding both (or only 21) of the vertical grip levers 21 and 22. Then, the buttocks are moved downward toward the toilet bowl 1, whereby the toilet bowl 1 is seated (the state shown in fig. 9 and 10).

The above is the procedure when moving from the wheelchair 10 to the toilet bowl 1. Next, a case where the care-receiver P moves from the toilet bowl 1 to the wheelchair 10 after the toilet stool is carried out will be briefly described. As shown in fig. 11, from the state of being seated on the toilet bowl 1, the hands are extended forward to hold the vertical grip bars 21, 22 (or only 21), and at the same time, the upper body is leaned against the vertical grip bars 21, 22 by standing up from the toilet bowl 1. In this state, the caregiver wears the pants and underwear. Then, the care recipient P turns around while holding both the vertical grip bars 21 and 22 (or only 21) so as to face the wheelchair 10 side backward. Then, the buttocks are moved downward toward the wheelchair 10, and the state of being seated on the wheelchair 10 is achieved.

In the above description, the case where the direction of entry of the wheelchair 10 into the toilet bowl 1 is set to a direction substantially perpendicular to the lateral direction as indicated by the arrow Y has been described, but the direction of entry of the wheelchair 10 may be set to an oblique lateral direction as indicated by the arrow Y2 in fig. 1, for example. Further, the extension lines of the arrow Y2 pass through the most protruding portions of the pair of left and right longitudinal grips 21, 22 in fig. 1.

Here, the entry from the area on the side away from the toilet bowl 1 with the arrow Y as a boundary is preferably performed from the area sandwiched by the arrow Y and the arrow Y2 to the center portion of the gasket portion 40. Further, regarding the entry from the toilet bowl 1 side with the arrow Y as a boundary, it is preferable to have a direction toward the center portion of the gasket portion 40 within a range where the wheelchair 10 does not interfere with the toilet bowl 1.

The first embodiment described above has the following advantages (a) to (G).

(A) The upper connecting part 23 connecting the upper ends of the pair of left and right grip bars 21, 22 and the lower connecting part 24 connecting the lower ends of the pair of left and right grip bars 21, 22 are provided, so that a ring-shaped structure which is closed by the pair of left and right grip bars 21, 22, the upper connecting part 23 and the lower connecting part 24 and has excellent strength is formed, and the load from the nursing person can be reliably received.

(B) The structure of the portion relating to the pair of left and right grip bars 21, 22 can be made stronger by providing the holding portion 31 extending in the vertical direction to connect the upper connecting portion 23 and the lower connecting portion 24 and located on the back side of the pair of left and right grip bars 21, 22. Further, since the holding portion 31 is located on the back side of the pair of left and right grip bars 21, 22, the holding portion 31 can be reliably prevented from coming into contact with the care recipient P when the care recipient P in the standing posture is supported.

(C) The receiving portion 40 is preferably provided in the holding portion 31, and the receiving portion 40 constitutes a pad portion that supports the front surface portion of the upper body of the care recipient in the standing posture, so that the care recipient P is supported by the receiving portion 40, and more stable support is obtained without causing the care recipient P to feel local pain. It is also preferable to provide the receiving portion 40 in the holding portion 31 that connects the upper and lower connecting portions 23 and 24, so that the receiving portion 40 is firmly held.

(D) The pair of left and right grip bars 21, 22 are supported by the wall surface 3 or floor surface via the holding portion 31, and the holding portion 31 can be effectively used as a connecting member (a part of a frame member) for connecting the pair of left and right grip bars 21, 22 to the wall surface 3 or floor surface. Further, since the holding portion 31 is located at the center portion of the armrest device 20 such as between the pair of left and right grip bars 21, 22 and between the upper and lower connecting portions 23, 24, it is also preferable to connect the pair of left and right grip bars 21, 22 to the wall surface 3 and the floor surface in a balanced manner.

(E) The pair of right and left vertical grips 21, 22 are projected in different directions from each other in a plan view from above, so that the caregiver P can easily grip the vertical grip in any case, regardless of whether the caregiver P intends to grip the left vertical grip 21 from the left side (toilet bowl 1 side) or the right vertical grip 22 from the right side (wheelchair 10 side). Further, the shape of the vertical grip 21, 22 is also based, but the upper connecting portion 23 and the lower connecting portion 24 can be shortened.

(F) One of the pair of left and right longitudinal grips 21, 22 protrudes more toward the front side than the other longitudinal grip, and thus when the care recipient P is supported by the pair of left and right longitudinal grips 21, 22, the one longitudinal grip preferably restricts the motion of the care recipient P to slide sideways without conscious attention. Further, it is also preferable to easily insert a hand between the longitudinal grip on the other side and the body of the person P to be cared for putting on and taking off clothes.

(G) One of the pair of left and right longitudinal grips 21, 22 located on the side farther from the toilet bowl 1 is projected more toward the front side than the other longitudinal grip, so that when the person P to be cared is supported by the pair of left and right longitudinal grips 21, 22, it is preferable that the one longitudinal grip restricts such an action that the body of the person P to be cared slides sideways without being conscious.

Fig. 12 shows a second embodiment of the present invention, and the same components as those in the above-described embodiment are denoted by the same reference numerals, and redundant description thereof is omitted (this is the same also in the third embodiment below). In the present embodiment, the bed for the care recipient P is denoted by reference numeral 100, and the armrest apparatus 20B is fixedly provided beside the bed 100. The armrest device 20B differs from the armrest device 20 in the above-described embodiment only in the frame portion. That is, base portion 32B (corresponding to 32) of frame portion 30B (corresponding to 30) is fixed to the floor surface, and a bracket portion corresponding to bracket portion 33 in the above embodiment is provided upright from base portion 32B and extends in the vertical direction.

A portable toilet 1B is carried into the vicinity of the armrest device 20B beside the bed 100. In fig. 12, reference numeral 4B denotes a backrest.

The care recipient P moves to the toilet bowl 1B from the sitting state on the bed 100 by using the armrest apparatus 20B. After the toilet is defecated, the armrest apparatus 20B is moved from the toilet 1B to the bed 100. The usage method of the armrest device 20B is the same as in the above-described embodiment.

In fig. 12, by using a wheelchair instead of the toilet 1B, the care-receiver P can move between the bed 100 and the wheelchair by using the armrest apparatus 20B.

Fig. 13 to 15 show a third embodiment of the present invention. The armrest device 20C in the present embodiment includes a pair of left and right vertical grips 121 and 122 (corresponding to the vertical grips 21 and 22 in the first embodiment) and a lower coupling portion 124 (corresponding to the lower coupling portion 24 in the first embodiment), as in the first embodiment. In the present embodiment, the pair of left and right grips 121 and 122 are formed in a shape overlapping each other (the length, thickness, degree of bending, and the like are all the same), and are arranged in parallel to each other. That is, the interval between the pair of right and left longitudinal grips 121 and 122 is the same in the up-down direction. Thus, the armrest device 20C can be used for both the case where the toilet bowl 1 is disposed on the left side and the case where the toilet bowl 1 is disposed on the right side. Further, end caps 123 having a substantially hemispherical shape or a rounded shape are provided at the upper ends of the vertical grips 121 and 122. Thus, the caregiver does not feel a sense of discomfort such as pain when gripping the upper ends of the vertical grips 121 and 122.

As in the case of the first embodiment, the lower ends of the pair of left and right vertical grips 121 and 122 are connected to each other by a lower connecting portion 124 extending substantially horizontally. In the third embodiment, the lower connecting portion 124 is composed of a rod-shaped lower grip 124a and a pair of left and right connecting covers 124b that connect the respective ends of the lower grip 124a to the lower ends of the left and right vertical grips 121 and 122.

The upper ends of the pair of left and right vertical grips 121, 122 are connected to each other by an upper connecting portion 130 (corresponding to the upper connecting portion 23 in the first embodiment). The upper connecting portion 130 has a split structure including a pair of left and right side portions 131 integrally formed on lower surfaces of upper end portions of the pair of left and right grip bars 121, 122, and a central connecting portion 132 connecting lower end portions of the pair of left and right side portions 131. The upper end portions of the vertical grip 121 and 122 protrude upward from the side portions 131, and have a substantially hemispherical shape or a rounded shape. Specifically, the end caps 123 having the outer peripheral surfaces of the substantially hemispherical shape or the rounded-chamfered shape as described above are provided at the upper end portions of the longitudinal grips 121, 122. Thus, the caregiver does not feel uncomfortable, such as pain, when gripping the upper ends of the vertical grips 121 and 122 with his or her fingers.

The upper coupling portion 130 is fixed to the vertical grips 121 and 122 by using a coupling bolt 133. Specifically, (the shaft portion of) the connecting bolt 133 is passed through the central coupling portion 132 and the side portions 131 from below (the back side) of the central coupling portion 132, and in this state, the tip end portion of the connecting bolt 133 is screwed to the nut provided in the vertical grip 121, 122. Thus, the central coupling portion 132 and the lateral portion 131 are fastened together to the vertical grip 121 or 122 by the coupling bolt 133.

In the embodiment, the lateral portions 131 are formed of metal or hard synthetic resin, and the central connecting portion 132 is formed of metal (e.g., iron-based metal). The side portions 131 are columnar, and the caregiver whose upper body leans against the longitudinal grips 121 and 122 can appropriately hold (or hook) the side portions 131 with his/her fingers. Therefore, the outer peripheral surface of the side portion 131 is rounded so as not to have a corner portion. The side portions 131 extend obliquely downward, and are set to an appropriate inclination necessary for the forward-tilted care recipient to hold with his/her fingers.

The side portion 131 is located slightly below the upper end positions of the vertical grips 121 and 122. Thus, in a state where the care recipient holds the side portion 131 with his or her fingers, the fingers are prevented from coming off the side portion 131 by the portions of the vertical grips 121 and 122 that protrude upward from the side portion 131.

The position of the center connecting portion 132 is retracted to a position considerably deeper than the pair of left and right vertical grips 121 and 122 by the pair of left and right lateral portions 131. That is, a large escape space S toward the inner side is formed between the pair of left and right grip bars 121 and 122 and at the upper portion thereof. Thus, the care-receiver leaning against the pair of left and right grip bars 121, 122 can position his chin in the avoidance space S, and a more anteverted posture can be obtained. This is preferable in terms of more reliably maintaining the standing posture of the care-receiver. Further, it is preferable for the care recipient who leans on the pair of left and right grip bars 121 and 122 to have a front part near the face thereof opened as the escape space S, and thus the care recipient does not feel a sense of pressure.

A socket 140 (corresponding to the socket 40 in the first embodiment) is disposed between the pair of left and right vertical grips 121 and 122. The receiving portion 140 has an attachment plate portion 141 formed by extending the core member upward, and the attachment plate portion 141 is integrally formed at the widthwise intermediate portion of the central connecting portion 132. That is, the mounting plate portion 141 is fixed by the bolt 142 in a state of being seated on the lower surface (back surface) of the central coupling portion 132. The receiving portion 140 can be formed of, for example, a ferrous metal or a hard synthetic resin.

The receiving portion 140 includes a shelf portion 140a extending short from the central connecting portion 132 toward the front side, and a downward extending portion 140b extending downward from the front end of the shelf portion 140 a. The lower end of the lower extension portion 140b is a free end. In the third embodiment, since the portion connecting the receiving portion 140 (the downward extending portion 140b) and the lower connecting portion 124 (the lower grip 124a) is not provided, there is no hindrance when the caregiver grips the lower connecting portion 124 (the lower grip 124 a).

An attachment portion 143 is disposed on the rear surface side of the receiving portion 140. The mounting portion 143 is disposed as a mounting plate portion 141 whose plate surface extends in the vertical direction and is integrally formed on the receiving portion 140 by welding or the like. The mounting portion 143 is positioned in contact with or near the rear surface of the substantially middle portion in the left-right direction of the downwardly extending portion 140b, and reinforces the receiving portion 140. The mounting portion 143 may be integrated (e.g., welded) with (the core material of) the receiving portion 140 in advance.

Here, at least the surface of the receiving portion 140 facing the care recipient may be configured as a pad portion formed of a member having cushioning properties. At least the surface of the central coupling portion 132 facing the care recipient may be covered with synthetic resin, synthetic rubber, or the like (including a cushion material). Further, a portion located below the central coupling portion 132 (an outer shape that improves the appearance of the rear side of the central coupling portion 132) may be covered with synthetic resin, synthetic rubber, or the like (including a cushion material).

The armrest device 20C described above can be fixed to a wall surface 160 (corresponding to the wall surface 3 in fig. 1) by the frame portion 150. The frame portion 150 generally has a base portion 151 and a bracket portion 152. The bracket portion 152 connects the base portion 151 and the attachment portion 143 (i.e., the central connection portion 132). In this way, the attachment portion 143 also functions as a coupling portion to be coupled to the extension portion 152b constituting the bracket portion 152.

The base portion 151 includes a guide portion 151a extending in the vertical direction, a pair of upper and lower protruding portions 151b extending from upper and lower ends of the guide portion 151a toward the wall surface 160, and a pair of upper and lower fixing portions 151c extending upward or downward from the protruding portions 151 b. The fixing portion 151c is fixed to the wall surface 160 by a fixing member 153 such as a bolt (see fig. 13 and 14).

The bracket portion 152 in the frame portion 150 includes a cylindrical body portion 152a extending horizontally, a plate-like protruding portion 152b integrally formed (for example, welded) on the front end portion side of the body portion 152a, and a sliding portion 152c formed on the base end portion of the body portion 152 a.

The extension 152b extends in a direction inclined at substantially 45 degrees with respect to the wall surface 160. The extension 152b is fixed to the mounting portion 143 by a fixing member 154 such as a bolt.

The slide portion 152c is fitted to the guide portion 151a of the base portion 151 so as to be slidable in the vertical direction. The sliding portion 152c is fixed to the guide portion 151a at a desired height position by a locking bolt, a locking pin, or the like of a height adjustment mechanism, not shown. In this way, in the armrest device 20C of the present embodiment, the height position can be adjusted.

Here, the length of (the main body portion 152a of) the bracket portion 152 may be adjustable. In this case, for example, the body portion 152a is formed as a two-part split structure which is slidably fitted to each other, and can be fixed by a locking bolt, a locking pin, or the like which locks the slide at a desired position. This allows adjustment of the distance of the armrest apparatus 20C from the wall surface 160.

In addition, the inclination angle of the armrest apparatus 20C with respect to the wall surface 160 can also be adjusted. In this case, for example, the sliding portion 152c of the bracket portion 152 is configured to be swingably coupled around the guide portion 151a of the base portion 151, and can be fixed at a desired swing position by, for example, a locking bolt, a locking pin, or the like for locking. Thus, the inclination angle of the armrest apparatus 20C (particularly, the pair of left and right vertical grips 121 and 122) with respect to the wall surface 160 can be adjusted.

The embodiments have been described above, but the present invention is not limited to the embodiments, and can be modified as appropriate within the scope described in the claims. In the case where the left hand is not free and the right hand is free, the toilet pan 1 may be positioned on the left side of the wheelchair 10 with respect to the arrangement shown in fig. 1, and the armrest apparatus 20 may be changed to a bilaterally symmetrical shape (the position of the front space K remains unchanged). The frame portion 30 is not limited to being fixed to the vertical wall surface, and may be fixed to a floor surface near the front space K (the frame is a desk type). The receiving portion 40 may not have cushioning properties. The upper coupling part 23(130) and the lower coupling part 24(124) may be provided with only one of them, or neither of them may be provided.

In the embodiment of fig. 13 to 15, the upper coupling portion 130 may be formed integrally with each other by, for example, a pipe material, a plate material, or the like, and the pair of left and right side portions 131 and the central coupling portion 132 may be formed integrally with each other. In the embodiment of fig. 13 to 15, the pair of left and right grip bars 121 and 122 may be arranged in a superimposed shape and in a bilaterally symmetrical manner so that the interval therebetween decreases as the grip bars face upward (the upper portion of the upper body of the care recipient is pushed between the upper portions of the grip bars 121 and 122, and the standing posture is more stably maintained).

The armrest device 20(20B, 20C) can be disposed at an appropriate position. For example, the armrest device 20 may be disposed beside a bed for a care recipient, and used for movement between the bed and a wheelchair. Further, the present invention can be used in a dressing room when a caregiver wears clothes on or off. Of course, the object of the present invention is not limited to the description, and implicitly includes providing an object that is actually preferable or is expressed as an advantage, and can be grasped as a toilet room, a toilet compartment, and the like having an armrest device.
