[Effects of Invention]

According to the nursing chair of the present invention, the rear space can be secured and the chair can be tilted.

Hereinafter, one embodiment of the bathing care system using the nursing chair of the present invention will be described with reference to the drawings.

Fig. 1 is a side view of the bathing care system, and Fig. 2 is a top view of Fig. 1. As shown in Figs. 1 and 2, the bathing care system is a system for taking care of the person in the bath. It has: a care chair 100 for the person to sit on; and a rail unit 200, which is installed in the bathtub 8. It is used to guide the chair unit of the nursing chair 100 located in the bathroom W to the bathtub 8. Hereinafter, first, the nursing chair 100 will be described, and then the guide rail unit 200 and its usage method will be described. In addition, in the following, for the convenience of description, description will be given in the direction shown in FIGS. 1 to 3.

＜1. Chair for nursing care＞ As shown in FIGS. 1 and 2, the nursing chair 100 of this embodiment includes: a chair unit 1 that seats a user such as a care recipient; a main body 2 that supports the chair unit 1; and a base 3, It supports the body part 2 movably. Hereinafter, each member will be described in detail.

＜1-1. Chair Unit＞ First, the chair unit will be described with reference to FIG. 3 as well. Figure 3 is an exploded perspective view of the support and the chair. As shown in FIGS. 1 and 2, the chair unit 1 of this embodiment includes: a support body 11 formed in an L-shape in a side view; a chair 12 that can move on the support body 11; and a fixing mechanism 13, It is used to fix the chair 12 on the support 11. The support 11 is formed by connecting a first part 111 extending substantially in the horizontal direction and a second part 112 extending substantially upward from the rear end of the first part 111.

As shown in FIGS. 1 and 3, the second part 112 includes a second part body 113 formed in a plate shape, and a rack (not shown) extending in the vertical direction is fixed to the back surface thereof. In addition, a pinion gear (not shown) exposed from the front surface of the main body 2 meshes with the rack. The pinion is driven to rotate in the forward and reverse directions by a motor (not shown) built into the main body 2. In addition, on both sides of the back surface of the second part main body 113, a pair of first guide rails 114 extending in the vertical direction are provided, and rollers (not shown) provided on the main body part 2 are rotatably fitted into these first guide rails 114. Thereby, the second part 112 can move up and down with respect to the main body 2. In addition, if the motor of the main body 2 is driven, the second part 112 and the first part 111 move up and down with respect to the main body 2. That is, the chair unit 1 is configured to move up and down with respect to the main body 2.

As shown in FIG. 3, the first part 111 includes a plate-shaped first part main body 115 and a pair of second guide rails 116, which are provided on both sides of the upper surface of the first part main body 115 and extend in the front-rear direction. The second guide rails 116 are formed in an L-shaped cross-section or a U-shaped cross-section. As described later, the roller 126 of the chair 12 is inserted between the first part main body 115 and the second guide 116. In addition, in the pair of second guide rails 116, three recessed portions (fixed portions) 117a to 117c are respectively formed at predetermined intervals in the front-rear direction. In these recesses 117a to 117c, as described later, the protrusion 138 of the fixing mechanism 13 is detachably fitted. Here, for convenience of description, the recesses arranged from the front to the rear are referred to as the first recess 117a, the second recess 117b, and the third recess 117c in this order. In addition, except for Fig. 3 and Fig. 6 described later, the recess 117 is omitted and shown.

Next, the chair 12 will be described. As shown in FIGS. 1 and 3, the chair 12 includes a seat 121 that extends in the front-rear direction; and a backrest 122 that is connected to the rear end of the seat 121 and extends substantially upward; and is formed in a side view L-shaped. In addition, the backrest portion 122 is provided with: a backrest body 123 connected to the seat 121; and an extension portion 124 that is rotatably connected to the upper end of the backrest body 123; and both sides are formed in a U-shaped cross-section bent on both sides . The extension 124 is formed to be less than 50% of the length of the backrest 122 in the upper and lower direction, and is mainly a part where the head of the person being cared for is placed. The side surfaces of the lower end of the extension portion 124 are rotatably connected to the side surfaces of the backrest body 123 by a shaft member (not shown) around an axis extending in the horizontal direction (left-right direction). Thereby, the extension part 124 is swingably connected to the backrest body 123.

In addition, one end of the first connecting member 127 is rotatably connected to two left and right connecting parts of the extension part 124 and the backrest body 123. That is, the first connecting member 127 is also connected to the shaft member connecting the extension portion 124 and the backrest body 123. On the other hand, the other end of the first connecting member 127 is rotatably connected to the side surface of the upper end of the second portion 112 of the support 11 (the side surface of the first rail 114). Furthermore, one end of the second connecting member 128 is respectively rotatably connected to the two side surfaces of the upper end of the extension portion 124, and the other end of each second connecting member 128 is rotatably connected above the first connecting member 127 On each side surface of the upper end of the second part 112 of the support 11.

At the lower end of the backrest body 123, a roller 126 having a rotating shaft extending in the horizontal direction is provided. The roller 126 is inserted into the second guide rail 116 of the first part 111 as described above. Therefore, the lower end of the backrest portion 122 can move in the front-rear direction along the second guide rail 116.

Since the seat part 121 and the backrest body 123 are integrally formed, for example, if the seat part 121 is pulled forward, the lower end of the backrest body 123 will move forward along the first part 111 along with this. Along with this, the backrest portion 122 also moves forward, but the forward movement is restricted by the two connecting members, and it rotates downward. At this time, for example, as shown in FIG. 4, the extension portion 124 of the backrest portion 122 is rotated downward by keeping the balance between the two connecting members and the first portion unchanged. On the other hand, since the upper right end of the backrest body 123 is connected to the first connecting member, it swings forward with respect to the first connecting member. That is, the inclination angle of the backrest body 123 with respect to the vertical direction becomes larger, and the body below the main head of the user sitting on the chair is supported in an inclined manner.

And, if the seat 121 is further pulled forward, as shown in FIG. 5, the backrest body 123 is inclined until the two connecting members 127, 128, the extension 124, and the second part 112 overlap in a side view State so far. In this way, the entire chair 12 is inclined on the support 11.

Next, the fixing mechanism 13 will also be described with reference to FIGS. 6A and 6B. 6A and 6B are side views showing the relationship between a part of the support body and the fixing mechanism. As shown in FIG. 6A, the fixing mechanism 13 includes a first connecting member 131, a second connecting member 132, and a third connecting member 133 that are installed on the lower surface of the seat 121 and arranged from the front side to the rear side, which constitute the connecting mechanism . The first connecting member 131 is rotatably fixed by the first shaft member 134 whose middle portion is fixed to the vicinity of the front end of the lower surface of the seat portion 121. The first shaft member 134 is a shaft member extending in the horizontal direction (left-right direction), and the second to fourth shaft members 135 to 137 described later also extend in the horizontal direction. In addition, an operating handle 139 is attached to the front end of the first connecting member 131. Therefore, as shown in FIG. 6B, when the operating handle 139 is lifted upward, the rear end of the first connecting member 131 rotates downward. In addition, the rear end of the first connecting member 131 and the front end of the second connecting member 132 are rotatably connected to each other by the second shaft member 135. Furthermore, the rear end of the second connecting member 132 and the front end of the third connecting member 133 are rotatably connected to each other by the third shaft member 136.

The third connecting member 133 is bent so as to protrude upward near the front end, and a fourth shaft member 137 is attached to the bent portion, and the fourth shaft member is fixed to the lower surface of the seat 121. Therefore, as shown in FIG. 6B, for example, if the front end of the third connecting member 133 is pushed backward and rotated downward, the rear end of the third connecting member 133 rotates upward. In addition, a protruding portion 138 extending in the horizontal direction is attached to the rear end of the third connecting member 133, and the protruding portion 138 is fitted into each of the concave portions 117a to 117c of each of the second rails 116 described above.

The fixing mechanism 13 constructed as above operates as follows. As shown in FIGS. 1 and 6A, if the protrusion 138 is fitted into the third recess 117c in the initial state, the seat 121 is fixed so as not to move on the first part 111. From this state, as shown in FIG. 6B, when the operating handle 139 is lifted upward, the rear end of the first connecting member 131 rotates downward, and accordingly, the second connecting member 132 is pushed backward. Furthermore, if the front end of the third connection member 133 is pushed back as the second connection member 132 moves rearward, the third connection member 133 rotates around the fourth shaft member 137 and the rear end rotates upward. As a result, the protrusion 138 is detached from the third recess 117c, and the seat 121 becomes a movable state on the first portion 111. If the operating handle 139 is pulled forward in this state, the seat 121 moves forward, and accordingly, the entire chair inclines.

And, for example, when the protrusion 138 is arranged on the first recess 117a, if the operating handle 139 is pushed downward, the first to third connecting members 131 to 133 move in the opposite direction to the above, and the third connecting member 133 follows The end rotates downward around the fourth shaft member 137, and the protrusion 138 is fitted into the first recess 117a. As a result, as shown in FIG. 5, the chair 12 is maintained in the most inclined state. In addition, FIG. 4 shows a state where the protrusion 138 is fitted into the second recess 117b.

＜1-2. Main body part＞ Next, the main body 2 will be described. As shown in FIG. 1, the main body 2 includes a rectangular parallelepiped-shaped housing 21 and a motor (not shown) built in the housing 21. The motor is used to rotate the pinion gear as described above. The front surface of the housing 21 is inclined so as to go downward and forward. In addition, a guide roller (not shown) is arranged on the front surface of the housing 21, and the guide roller is fitted into the first guide rail of the chair unit 1 described above. Thereby, the chair unit 1 can move up and down on the front side of the housing 21. In addition, since the front surface of the housing 21 is inclined as described above, the chair unit 1 is also configured to move up and down along the inclination. For example, if the chair unit 1 moves downward with respect to the housing 21, it moves slightly forward.

In addition, as will be described later, when the care receiver takes a bath, the chair unit 1 and the main body portion 2 are separated from the care chair 100 and move toward the bathtub 8 side.

＜1-3. Abutment＞ Next, the base 3 will be described. The base 3 includes a base 31 provided with a plurality of wheels 351 and 352; a first rail member 32 supporting the main body 2; and a support 33 extending upward from the base 31 and supporting the first rail member 32.

The base 31 is provided with a pair of rod-shaped support members 311 extending in the front-rear direction, and a front wheel 351 and a rear wheel 352 are respectively mounted on the lower side of the front and rear ends of each support member 311. The two supporting members 311 are arranged in parallel at a predetermined interval in the left-right direction, and the front end side is connected by the first connecting member 312. On the other hand, the two supporting members 311 are connected by a second connecting member (not shown) near the middle in the front and rear directions. The above-mentioned supporting portion 33 extends upward from the second connecting member and supports the second connecting member from the lower side. 1 rail member 32.

The first rail member 32 has a rail extending in the left-right direction, and the lower end surface of the housing 21 is movably fitted into the rail. Thereby, the housing 21 can move in the left-right direction along the first rail member 32. In addition, when the housing 21 is positioned on the first rail member 32, its position can be locked. In addition, the first rail member 32 is provided at substantially the same height as the second rail member 9 provided on the upper surface of the bathtub 8 as described later.

＜2. Rail unit of bathtub＞ Next, the guide rail unit 200 of the bathtub will be described. First, the bathtub 8 will be described. As shown in FIG. 2, the bathtub 8 has a first wall 81 and a second wall 82 extending in parallel in the front-rear direction, and a third wall 83 and a fourth wall 84 extending in parallel in the left-right direction, and are formed in a plan view. When it is rectangular. The first wall part 81 is arranged on the left side (bathroom W side), and the second wall part 82 is arranged on the right side, which is equal to the lengthwise extension of the bathtub 8. On the other hand, the third wall portion 83 is arranged on the front side, and the fourth wall portion 84 is arranged on the rear side, which extends in the short-side direction of the bathtub 8.

The rail unit 200 includes a first fixture 71 arranged along the upper surface of the first wall portion 81 and a second fixture 72 arranged along the upper surface of the second wall portion 82. A clamping member (not shown) that clamps each wall portion 81, 82 is installed under the fixtures 71, 72, and each fixture 71, 72 is fixed to each of the wall portions 81, by the clamping member. 82.

The upper surfaces of the two fixtures 71, 72 are formed flat, and the second rail member 9 extending in the left-right direction is attached so as to span the fixtures 71, 72. A rail is provided on the upper surface of the second rail member, and the housing 21 of the main body 2 of the above-mentioned chair unit is slidable.

That is, the second rail member 9 and the first rail member 32 of the nursing chair 100 are located at approximately the same height, and when the left end of the second rail member 9 is in contact with the right end of the first rail member 32, the housing of the main body 2 21 can slide over the first rail member 32 and the second rail member 9. In addition, the left end of the second rail member 9 and the right end of the first rail member 32 can be locked. Furthermore, the housing 21 received by the second rail member 9 can be locked on the second rail member 9 so as not to move.

＜3. How to use the bathing care system＞ Next, the method of using the bathing care system constructed as described above will also be described with reference to Figs. 7-9. Here, the operation of moving the chair 12 of the nursing chair 100 arranged in the bathroom W into the bathtub 8 and immersing the care receiver sitting on the chair 12 in the bathtub 8 will be described.

First, as shown in FIG. 1, the chair unit 1 is lowered with respect to the main body 2, and the person to be cared for is seated on the chair 12. Next, after operating the fixing mechanism 13 to tilt the chair 12, as shown in FIG. 7, the chair unit 1 is raised to a position higher than the first wall 81. In Fig. 7, the protrusion 138 is fitted into the first recess 117a. That is, the chair 12 is most inclined. However, as shown in FIG. 4, the protrusion 138 may be fitted into the second recess 117b. In addition, at the front and rear, the right end of the first rail member 32 and the left end of the second rail member 9 are connected.

Next, as shown in FIG. 8, the main body 2 is slid from the first rail member 32 toward the second rail member 9. In this way, if the chair unit 1 and the main body 2 are located above the bathtub 8, the main body 2 is locked at this position without sliding.

Next, the motor of the main body 2 is driven, and as shown in FIG. 9, the chair unit 1 is lowered into the bathtub 8. In this way, the care recipient can enter the bathtub 8 while being seated on the chair 12 and soak in the bath water. After bathing, the chair unit 1 is raised on the contrary. If the chair unit 1 rises to a position beyond the upper surface of the bathtub 8, the sliding lock of the main body 2 is released and the main body 2 slides toward the bathroom W side. And, when the main body part 2 moves to the 1st rail member 32, it will lock. After that, after the chair 12 is lowered, the lock between the second rail member 9 and the first rail member 32 is released, and the care chair 100 is moved together with the person to be cared for.

＜4. Features＞ According to the nursing chair of this embodiment, the following effects can be obtained.

(1) Since the chair 12 is provided in front of the L-shaped support 11 when it is formed in a side view, and the chair 12 is inclined, even if the chair 12 is greatly inclined, it does not move to the rear of the support 11. Therefore, the head of the care recipient sitting on the chair 12 does not fall to the back of the support 11. Furthermore, since the backrest 122 moves backward when the chair 12 is tilted, the position of the front end of the seat 121 does not change significantly. Based on the above, since the chair 12 does not move much, the anxiety of the person being cared for can be suppressed.

(2) Since the backrest portion 122 of the chair 12 is composed of a backrest body 123 and an extension portion 124, and the extension portion 124 is connected to the support body 11 by two connecting members 127 and 128 arranged up and down, even if the backrest body 123 is inclined , The angle of the extension 124 is also substantially unchanged. In addition, since the head of the person to be cared for is mainly arranged at the extension 124, the angle of the head does not change, and the body below the head is inclined. Therefore, it can further alleviate the anxiety of the person being cared for.

(3) Since the chair 12 does not move to the back of the support body 11, there is no need for an action area for tilting the chair 12 behind the support body 11. Therefore, the main body 2 can be brought close to the fourth wall 84 of the bathtub 8, and the bathtub 8 can be used in a spacious manner. In addition, after the support 11, the caregiver's movement space can be ensured.

(4) Since the chair 12 is tilted by moving the seat 121 forward and the backrest 122 downward, the force required for tilting can be reduced. In addition, when the chair 12 is tilted, a large void space is formed between the support 11 and the chair 12. Therefore, the bathtub 8 can be used spaciously. In addition, since the seat position of the cared person can be prevented from increasing due to the inclination of the chair 12, the anxiety of the cared person can also be suppressed by this.

(5) The chair 12 tilts in a well-balanced manner by moving the seat 121 forward and the backrest 122 downward. That is, since the entire chair is not tilted in a lifted manner as in the previous example, it is possible to prevent falling. Furthermore, since the force acting on the support body 11 or the main body 2 supporting the chair 12 is dispersed, the force acting on the support body 11 and the like can be suppressed. As a result, damage to the nursing chair 100 can be prevented.

(6) Since the operating handle 139 is provided in front of the seat 121, the chair 12 can be tilted from the side of the person who is seated. Therefore, when the operation handle 139 is operated, the caregiver can perform operations at a position that is in line with the line of sight of the care recipient, so that the care recipient's anxiety can be suppressed.

＜5. Examples of changes＞ The embodiments of the present invention have been described above, but the present invention is not limited to the above-mentioned embodiments, and various changes can be made without departing from the gist. For example, the following changes can be made. In addition, any one of the following modifications can be used, or a plurality of aspects can be combined without any abnormality.

＜5-1＞ The structure of the fixing mechanism 13 for fixing the inclined state of the chair 12 is not particularly limited, and can be in various forms. That is, if the chair 12 can be tilted manually, the structure is not particularly limited. In addition, the protrusion 138 is fitted into the recess 117 in order to fix the inclined position. However, even if it is a mechanism other than this, the inclined position may be fixed.

＜5-2＞ In the above-mentioned embodiment, although the two connecting members 127 and 128 are used when connecting the chair 12 and the support 11, for example, as shown in FIG. 10A, only the second connecting member 128 may be used. That is, it is possible to connect the extension part 124 and the support body 11 with the connection member 128 instead of attaching a connection member to the connection part of the backrest body 123 and the extension part 124. Even with this configuration, as shown in FIG. 10B, when the backrest body 123 is inclined, the extension portion 124 is suppressed from being greatly inclined. Therefore, the face of the care recipient can be restrained from facing upwards, and the anxiety of the care recipient can be alleviated.

＜5-3＞ In addition, the extension portion 124 may not be provided, and the backrest portion 122 may be formed by only the backrest body 123. For example, as shown in FIG. 11A, the upper end of the backrest body 123 and the support 11 may be connected by the connecting member 127. In this case, as shown in FIG. 11B, the body of the person to be cared for is inclined together with the inclination of the backrest body 123. In addition, since the extension 124 is not provided, the head of the care recipient can move freely regardless of whether the backrest body 123 is tilted or not. Therefore, the face of the care receiver can be suppressed from being forced upward.

＜5-4＞ As mentioned above, the presence or absence of extensions, the position and number of connecting members can be changed as appropriate. That is, it is only necessary to connect at least a part of the backrest to the support via at least one connecting member. In addition, as long as the seat part 121 of the chair 12 moves forward, and the backrest part is formed by a connecting member that is inclined and lowered. For example, the backrest 122 (or the backrest body 123) may be bent near the middle, and a connecting member may be provided at the bent portion.

＜5-5＞ In the above embodiment, the chair 12 is tilted manually, but it can also be tilted electrically.

＜5-6＞ The mechanism for moving the support 11 up and down with respect to the main body 2 is not particularly limited, and may be a mechanism other than a rack and pinion. In addition, although the main body 2 is slidable relative to the base 3, this structure is not essential. The main body 2 may be simply fixed to the base 3 so that the support 11 can move up and down relative to the main body 2. .

＜5-7＞ The structure of the base 3 is not particularly limited, and it may have no wheels. Also, it can be moved by a mechanism other than wheels.
