DETAILED DESCRIPTION

[0044] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the present invention is not limited to the following embodiments, and it should be understood that within the scope of the gist of the present invention, based on the common knowledge of those skilled in the art, design changes, improvements, etc. may be appropriately applied.

[0045] Figure 1 to Figure 3 An example of a nursing device K according to an embodiment of the present invention is shown. Figure 1 to Figure 3 , an example in which the care device K is provided in the toilet bowl 1 is shown. Figure 1 1 is a plan view showing an example of a bathroom in which the care device K is installed in the toilet 1. Figure 2 1 is a side view showing a state in which the care device K is used to support the upper body of a care receiver P seated on the toilet 1. Figure 3 It is a perspective view showing a state in which the front arm member 30 of the care device K is located at the retracted position.

[0046] here, Figure 1 This shows an example of a wheelchair-accessible restroom (restroom room, restroom cubicle). Figure 1 In the figure, reference numeral 1 is a toilet seat. In addition, a handrail device T is provided on the right side of the toilet seat 1. The handrail device T is used to enable the care receiver P to maintain a standing posture.

[0047] The care device K comprises: a base member 10 disposed near a seat on which the care receiver P sits (e.g., the seat 1a of the toilet 1); and a side member 20 mounted on the base member 10 and located to the side of the care receiver P sitting on the seat 1a.

[0048] The base member 10 has: a loading portion 13, which is arranged on the floor; a pair of left and right longitudinal support members 11, which are erected on each loading portion 13; and a crossbar member 12, which extends in the left and right directions and connects the upper ends of the pair of left and right longitudinal support members 11 to each other. The overall shape is a door. The components constituting the base member 10 are formed by metal square tubes. Between the pair of left and right longitudinal support members 11, the rear part of the toilet 1 is arranged in the space below the crossbar member 12. The base member 10 is a floor-standing type that is not affected by the structure of the toilet 1 (flush valve, low-level water tank). In addition, the base member 10 (the loading portion 13) can be arranged near the toilet 1, and can be fixed relative to the toilet 1, or fixed relative to the ground. In addition, a gap adjustment member 14 for filling the gap between the toilet 1 and the left and right longitudinal support members 11 is installed.

[0049] The side member 20 of the nursing device K includes a pair of left and right side frame members 21 and a pair of left and right front arm members 30. The side frame members 21 and the front arm members 30 constitute a support member in the nursing device K. In this embodiment, the nursing device K further includes a rear frame member 23 and a movable connection mechanism 40.

[0050] The side frame portions 21 are provided with a pair of left and right parts, each of which is bent into a U-shape that is open to the rear. In addition, the lower end of the side frame portion 21 is connected to the movable connecting mechanism 40. In addition, the pipe material described below is composed of, for example, a metal core material and a synthetic resin covering material, but is not limited to this. Each side frame portion 21 generally has an upper frame portion 27 extending in the front-to-back direction, a lower frame portion 28 that temporarily extends downward from the front end of the upper frame portion 27 and then extends to the rear, and a longitudinal frame portion 29 that connects the upper frame portion 27 and the lower frame portion 28. In addition, the rear end of the lower frame portion 28 is swingably mounted to the longitudinal support member 11 via the movable connecting mechanism 40.

[0051] In the pair of left and right side frame parts 21, the rear ends of the upper frame parts 27 are connected to each other through the rear frame part 23 extending in the left and right direction in a horizontal state. In the present embodiment, the side frame parts 21 and the rear frame part 23 are formed integrally by bending the same pipe. In addition, the side frame parts 21 and the rear frame part 23 can also be formed as different parts and assembled in a manner of connecting them. By connecting the pair of left and right side frame parts 21 and the rear frame part 23, the overall rigidity is improved. In addition, by swinging one side frame part 21, the other side frame part 21 also swings in conjunction with it. A backrest component 25 is installed on the rear frame part 23.

[0052] The movable connection mechanism 40 has a connection bracket 41 fixed to the vertical support member 11 in the base member 10. The side frame portion 21 (the rear end portion of the lower frame portion 28) is connected to the connection bracket 41 via a connection portion 42 so as to be able to swing in the up-and-down direction. The side frame portion 21 can change its angle (forward tilt angle) by swinging around the connection portion 42 as the center.

[0053] Next, the front arm member 30 includes a rod-shaped member 60 formed into a roughly L-shape by bending a pipe and a support member 90 mounted on the rod-shaped member 60. The rod-shaped member 60 has a main body portion 61 on which the support member 90 is mounted and a mounting portion 62 that constitutes a side mounted on the connecting bracket 41. That is, the rod-shaped member 60 has a mounting portion 62 along the upper frame portion 27 in the side frame portion 21 and a main body portion 61 bent approximately 90 degrees and extended from the mounting portion 62. Such a front arm member 30 is respectively provided on the left and right side frame portions 21. A cap 63 having a roughly hemispherical shape or an R-chamfered shape is provided at the front end of the main body portion 61. A joint member (not shown) is mounted on the rear end portion of the mounting portion 62. The joint member is formed of, for example, metal, and is fixed to the mounting portion 62 formed of a pipe by a fixing member such as a bolt. The support member 90 is used to receive a part of the body of the person being cared for P and is detachably mounted on the rod-shaped member 60. For example, as Figure 2As shown, the support member 90 is attached to the rod-shaped member 60 so as to be located in front of the care-receiver P sitting on the seat 1a. In addition, the arm contact member 24 is attached to the attachment portion 62 connecting the bracket 41 and the rod-shaped member 60.

[0054] The mounting portion 62 of the rod-shaped member 60 and the upper frame portion 27 of the side frame portion 21 are connected via the connecting bracket 26. The connecting bracket 26 is fixed to the side frame portion 21 and the front arm member 30 is rotatably mounted. Thus, the rod-shaped member 60 can selectively take a use position in which the main body 61 with the support member 90 mounted thereon extends in the horizontal direction (for example, see Figure 2 ) and its front end facing upwards (refer to Figure 1 as well as Figure 3 ). In addition, the main body 61 of the rod-shaped member 60 can be locked in rotation by the connecting bracket 41 in the escape position.

[0055] Here, a support member 90 for supporting the upper body of the care receiver P is mounted on the main body 61 of the pair of left and right rod-shaped members 60. In this embodiment, the mounting structure of such a support member 90 has a particularly important structure. Figures 4 to 8 The mounting structure of the support member 90 with respect to (the main body 61 of) the rod-shaped member 60 will be described in more detail.

[0056] here, Figure 4 yes Figure 1 The illustrated care device is an enlarged perspective view of a main portion of a support member attached to a rod-shaped member of a front arm member as viewed from the front side (the side opposite to the side that supports the body of the care receiver). Figure 5 is from Figure 4 The supporting member shown is a partially cutaway perspective view as viewed from the back side (the side that supports the body of the care receiver). Figure 6 This is an enlarged perspective view of the main parts for explaining the mounting state of the support member to the front arm member. Figure 7 This is a cross-sectional view perpendicular to the axis of the front arm member for explaining that the support member can rotate in the circumferential direction of the rod-shaped member. Figure 8 yes Figure 7 A cross-sectional view along the axis of the front arm component is shown.

[0057] First, the support member 90 includes: a base member 50 having a cylindrical portion 51 that can be inserted along the axial direction of the rod-shaped member 60. A pair of plate-shaped portions 52 protruding in a direction orthogonal to the axial direction of the cylindrical portion 51 are provided on the side surface of the cylindrical portion 51, and the support member 90 that receives a part of the body of the care recipient P (for example, can contact a part of the body of the care recipient P) is provided in a manner covering one side of the base member 50. In the present embodiment, the support member 90 functions as a chest contact member with respect to the care recipient P. As the support member 90, for example, an elastic member (a member having elasticity such as rubber or synthetic resin), an armrest member for maintaining the posture of the care recipient P, and a leaning member can be cited. The support surface 95 of the support member 90 that receives a part of the body of the care recipient P is formed into a curved surface. A mounting groove is formed on the side of the support member 90 opposite to the support surface 95 side, and includes a curved groove 91 into which the inner portion 51B of the cylindrical portion 51 is inserted, and a shallow groove 92 into which the plate-like portion 52 is inserted. The support member 90 is configured so that when inserted into (the inner portion 51B of) the cylindrical portion 51, the locking hole 73 provided on the outer portion 51A of the cylindrical portion 51 is exposed to the outside. The base member 50 can be formed of metal, hard synthetic resin, etc. The support member 90 is bonded and fixed to the base member 50.

[0058] Support member 90 is detachably attached to rod-shaped member 60 by being inserted into (the cylindrical portion 51 of) base member 50 along the axial direction X of rod-shaped member 60. By attaching support member 90 to rod-shaped member 60, support member 90 is disposed facing care receiver P seated on toilet bowl 1.

[0059] In this embodiment, the nursing device K has: a positioning mechanism 80 that positions the mounting position of the support member 90 in the axial direction X; and a locking mechanism 93 that fixes the support member 90 in a manner that it stays at the mounting position. With this configuration, the support member 90 can be easily disassembled as needed, and the support member 90 can be effectively prevented from accidentally falling off.

[0060] In the present embodiment, as the positioning mechanism 80, a locking portion 81 is provided on the outer periphery of the rod-shaped member 60, and a locked portion 82 is provided on the inner periphery of the base member 50. The locking portion 81 of the rod-shaped member 60 is formed by fixing a guide pin composed of a bolt and a part of which protrudes from the outer peripheral surface of the rod-shaped member 60. The locked portion 82 of the base member 50 is formed by a groove-shaped portion formed by partially cutting off one end side of the cylindrical portion 51 of the base member 50 in the circumferential direction. With the positioning mechanism 80 configured in this way, when the support member 90 is inserted in the axial direction X of the rod-shaped member 60, the movement to a position forward of the mounting position in the axial direction X can be effectively restricted, and the support member 90 can be positioned at an appropriate mounting position in the axial direction X of the rod-shaped member 60.

[0061] The locking mechanism 70 is used to fix the support member 90 positioned by the positioning mechanism 80 in a manner that it stays in an appropriate installation position. In this embodiment, the locking mechanism 70 includes: a locking member 72 having a convex portion 71 that protrudes radially outward from the outer peripheral surface of the rod-shaped member 60 and can be immersed in the interior of the rod-shaped member 60; and a locking hole portion 73 that is provided in the base member 50 and can be inserted into the convex portion 71.

[0062] When the support member 90 is positioned by the positioning mechanism 80 at the installation position in the axial direction X, the convex portion 71 of the locking member 72 is fixed in the installation position by being inserted into the locking hole portion 73. Then, by receiving a pressing operation by an operator such as the care receiver P or a caregiver (not shown) using the care device K, the convex portion 71 immersed in the interior is disengaged from the locking hole portion 73, and the fixation of the support member 90 in the axial direction X is released.

[0063] In the present embodiment, the locking member 72 of the locking mechanism 70 is configured to apply force to the protrusion 71 in the radially outward direction. Therefore, when the support member 90 is mounted on the rod-shaped member 60, the locking member 72 can move the base member 50 in the axial direction X in a state where the protrusion 71 is pressed against the inner peripheral surface of the base member 50 (the cylindrical portion 51) and buried while overcoming the elastic force. With such a configuration, the support member 90 can be mounted on the rod-shaped member 60 and fixed in a state where it is positioned by the positioning mechanism 80.

[0064] As the locking member 72 for urging the protrusion 71 in the radially outward direction, there can be cited a member composed of an elastic sheet 74 disposed inside the cylindrical rod-shaped member 60. The elastic sheet 74 is, for example, a metal plate bent into a V-shape (or a U-shape) with both ends separated, and the protrusion 71 protruding in the radially outward direction from the outer peripheral surface of the rod-shaped member 60 is disposed on one end side. The other end side of the elastic sheet 74 is disposed in contact with the inner peripheral surface of the cylindrical rod-shaped member 60, thereby urging the protrusion 71 disposed at the one end side in the radially outward direction.

[0065] The convex portion 71 is preferably arranged in a manner avoiding a portion of the support member 90 that can contact a part of the body of the care recipient P, and more preferably arranged in a portion that is difficult for the user's hand to contact when the support member 90 mounted on the rod-shaped member 60 is used as an auxiliary member such as an armrest. For example, it is preferred that the convex portion 71 is arranged in a manner protruding on the surface on the side opposite to the side on which the support member 90 for receiving a part of the body of the care recipient P is arranged when the care device K is normally used, and further arranged in the middle part from the insertion front end to the insertion end in the axial direction X of the base member 50 or a position closer to the insertion front end than the middle part. By configuring in this way, in both cases when the care device K is normally used and when the user grasps the support member 90 as an auxiliary member such as an armrest, erroneous operation caused by accidental contact with the convex portion 71 can be effectively suppressed. Therefore, when the front arm member 30 is in the use position, even if the care receiver P leans on the support member 90, the support member 90 will not accidentally come off from the rod-shaped member 60, and when the front arm member 30 is in the escape position, even if the care receiver P grabs the support member 90, the support member 90 will not accidentally come off from the rod-shaped member 60. In addition, by providing the locking mechanism 70 as described above, when cleaning the support member 90, it can be easily removed from the rod-shaped member 60, and the support member 90 after cleaning can also be easily installed.

[0066] In this embodiment, the support member 90 includes an elastic member (elastic member such as rubber or synthetic resin) integrated with the base member 50 so as to cover one side thereof. The support member 90 (elastic member) attached to the rod-shaped member 60 flexibly supports the upper body of the care receiver.

[0067] The support component 90 is installed in a state where it can rotate in the circumferential direction of the rod-shaped component 60, and the locking hole portion 73 is formed in a manner that extends in the circumferential direction to limit the rotation of the support component 90 within a specified angle range. In addition, the locked portion 82 of the positioning mechanism 80 is also formed in a manner that extends in the circumferential direction to limit the rotation of the support component 90 within a specified angle range, similar to the locking hole portion 73. With this structure, the support component 90 can rotate in the circumferential direction at a specified angle relative to the rod-shaped component 60. Therefore, depending on the physique of the person being cared for, the support component 90 installed on the rod-shaped component 60 can be appropriately rotated in the circumferential direction to always be in a posture suitable for support. Figure 7 In FIG. 1 , the support member 90 at the end of the rotation stroke is indicated by a two-dot chain line.

[0068] The above is an explanation of the embodiment, but the present invention is not limited to the embodiment and can be appropriately changed within the scope of the claims. The front arm member 30 can also swing around the axis extending in the vertical direction (swing in the horizontal plane) to change the position between the use position and the avoidance position. Fig. 9 In the nursing device K2 shown, the lower frame portion 28α and the longitudinal frame portion 29α are replaced in the front and rear directions from the above-mentioned embodiment, so that the upper end of the longitudinal frame portion 29α is continuous with the rear frame portion 23. In addition, the front arm member 30α of the nursing device K2 is formed as a whole with the main body 61α of the rod-shaped member 60α and the upper frame portion 27α (side member), and the mounting portion 62α is extended downward from the rear end of the upper frame portion 27α. Moreover, the mounting portion 62α of the front arm member 30α is swingably mounted on the longitudinal frame portion 29α by connecting the bracket 26α. The front arm member 30 in the avoidance position takes a posture state extending in the up-down direction or a posture state extending in the horizontal direction, for example, toward the front or outside of the seat, and the front arm member 30 is locked in the avoidance position, which is preferred in that the front arm member 30 in the avoidance position can be used as an armrest by the caregiver or the person being cared for. The front arm member 30 may be provided only on one of the pair of left and right side frame portions 21. Fig. 9 Since the other parts of the nursing device K2 shown are the same as those in the above-mentioned embodiment, the same symbols are attached to the same structures in the drawings, and the description thereof is omitted.

[0069] Figures 4 to 8 The support member 90 shown is formed in such a manner that the locking hole portion 73 and the locked portion 82 provided on the cylindrical portion 51 of the base member 50 extend along the circumferential direction of the rod-shaped member 60, but, for example, the locking hole portion 73 may be sized to fit the convex portion 71, and the locked portion 82 may be sized to fit the locking portion 81, and the support member 90 may not rotate at a predetermined angle in the circumferential direction, and may also be shaped to cover the entire circumference of the rod-shaped member 60. The support member 90 detachably mounted on the rod-shaped member 60 may not have a cushioning property, and, for example, the support member 90 may be a member such as a backrest or an armrest that covers a part of the rod-shaped member 60. There is no particular limitation on the material of such a support member 90, and it may be, for example, wood, synthetic resin, metal, etc., and preferably, its surface is composed of a flat surface or a smooth curved surface so that it can be pressed against a part of the body of the care receiver P without causing pain.

[0070] Although not shown in the figure, the rear frame portion 23 may also be provided with Figures 4 to 8The rod-shaped member 60 having the protrusion 71 shown in the figure uses the backrest member 25 provided on the rear frame member 23 as the "support member" in the present invention. In addition, in the absence of the rear frame member 23, the rod-shaped member 60 having the protrusion 71 may be provided on the crossbar member 12 of the base member 10, or the protrusion 71 may be provided on the crossbar member 12 itself, thereby forming the "rod-shaped member" in the present invention. In addition, the arm contact member 24 may be used as the "support member" in the present invention by providing the "locking mechanism" in the present invention on the mounting portion 62 of the rod-shaped member 60. Furthermore, the rod-shaped member 60 having the protrusion 71 may be provided on the side member 20, or the protrusion 71 may be provided on the side member 20, thereby forming the "rod-shaped member" in the present invention.

[0071] In addition, in the present embodiment, a locking portion 81 is provided on the outer periphery of the rod-shaped member 60, and a locked portion 82 is provided on the inner periphery of the base member 50, but the locking portion 81 as the positioning mechanism 80 may be provided on either the outer periphery of the rod-shaped member 60 or the inner periphery of the base member 50, and the locked portion 82 that locks the locking portion 81 may be provided on the other.
