It has a wide central portion 2a to be formed, and narrow ends 2b1 and 2b2 extending from both sides of the central portion 2a to the left and right and wound around the abdomen side of the care recipient. The central portion 2a has a pair of upper side and a pair of lower side diagonal slits 2c facing in parallel, a pair of upper side and a pair of lower side diagonal slits 2d facing in parallel, and a pair of vertically elongated slits 2e. As shown in FIG. 1, the left diagonal slits 2c are formed side by side from the top to the left diagonally downward direction (for example, a direction forming 30 ° with respect to the vertical direction), and the longitudinal direction of each slit (long hole) is right. It is tilted diagonally downward. The right diagonal slits 2d are formed side by side in the diagonally downward right direction (for example, 30 ° with respect to the vertical direction) from the top, and the longitudinal direction of each slit (slot hole) is inclined diagonally downward to the left. There is. That is, the left diagonal slit 2c and the right diagonal slit 2d are formed to be inclined. Further, as shown in FIG. 1, the left end portion 2b1 of the central portion 2a has a pair of vertically elongated slits 2f.

The fixing member 3 is made of a water-resistant or water-repellent member that can be attached to and detached from the support member 2, and has buckle portions 3a that can be fastened to each other at both ends. Both ends of the fixing member 3 are inserted into the vertically long slits 2e and 2f of the support member 2 from above the support member 2 and fastened by the buckle portion 3a.

The locking member 4 is a water-resistant or water-repellent member that can be attached to and detached from the support member 2 and has a width narrower than that of the fixing member 3 to lock and fix the body holding device 1 to the transfer device.

The locking member 4 has a bifurcated main body locking portions 4a1, 4a2 that face each other in the vertical direction, and a pair of diagonally crossing locking portions 4b1, 4b2 that diagonally intersect between the main body locking portions 4a1, 4a2. The locking member 4 is also inserted through a pair of upper left diagonal slits 2c and a string-shaped upper left diagonal locking portion 4d having a buckle portion 4c at the end, and a lower pair of left diagonal slits 2c and an end portion. A string-shaped diagonal locking portion 4f on the lower left side having a buckle portion 4e, and a string-shaped diagonal locking portion 4h on the upper right side having a buckle portion 4g at the end portion inserted through a pair of upper right diagonal slits 2d, and a lower side. It is inserted into a pair of right diagonal slits 2d and has a string-shaped lower right diagonal locking portion 4j having a buckle portion 4i at the end. The main body locking portions 4a1 and 4a2 are separated in parallel at substantially regular intervals on the central side, approach each other as they approach both ends, and are connected at both ends, and locking metal fittings (locking tools) 5 as locking tools at both ends. Is installed. The locking metal fitting 5 is a metal fitting that is locked to the rotation operation arm 18, and has a plurality of holes, two insertion holes 5a and 5b and one keyhole-shaped locking hole 5c in this embodiment.

As shown in FIG. 1 (b), which is an enlarged view of the broken line A in FIG. 1 (a), the main body locking portions 4a1 and 4a2 are inserted into the insertion holes 5a of the locking metal fitting 5, and then the main body locking portions 4a1. , 4a2 are formed in an endless shape in which both ends are connected. The main body locking portions 4a1 and 4a2 form a first locking member, and a branch member 4a3 as a second locking member branched from the first locking member and folded back and connected to the insertion hole 5b and the insertion hole 5a. Have. The seam 4a5 is a seam at a portion where the end portion of the branch member 4a3 folded back through the locking holes 5a and 5b is sewn to the branch member 4a3, and the seam 4a6 is the branch member 4a3 and the main body locking portion. This is the seam of the portion where 4a1 is sewn together. With the first locking member and the second locking member, the transfer device 10 (described later) is a branched second locking member even if the first locking member is cut during the transfer operation of the care recipient. Since the connection with is not released, safety can be improved. Further, the branch member 4a3 is provided in a loose state so that tension is not applied to the branch member 4a3 when connected to the rotation operation arm (described later) of the transfer device 10.

In the above body holding orthosis 1, as shown in FIGS. 4 and 5, the support member 2 is wound around the back and waist of the care recipient M from the abdomen, and the fixing member 3 is provided on the support member 2 from above. It is inserted into the vertically long slits 2e and 2f, and the buckle portions 3a at both ends thereof are fastened, whereby the fixing member 3 is wound around the support member M from above the support member 2 and the support member 2 is fixed to the care recipient M. To. By this winding fixing, the support member 2 is prevented from being displaced from the required positions of the back and waist of the care recipient M.

As shown in FIG. 5, the locking metal fittings 5 at both ends of the main body locking portions 4a1 and 4a2 of the locking member 4 rotate the transfer device 10 from the state where the body holding device 1 is attached to the care recipient M. It is locked to any of the three locked metal fittings 40a to 40c (locked portion) provided on the arm 18.

As shown in FIG. 5, when the rotation operation arm 18 of the transfer device 10 is rotated in the clockwise direction, the locking metal fitting 5 on the body holding device 1 side becomes the locked metal fitting 40a to 40c on the transfer device 10 side. Since it is hooked on any of the above, the person requiring care M who is seated on the seat surface portion 20 has a predetermined angle forward and upward with respect to the horizontal indicated by the arrow B by the main body locking portions 4a1 and 4a2 of the body holding device 1. For example, it can be lifted at 30 °. When the care recipient M is lifted, tension is applied to the lower main body locking portion 4a2 among the main body locking portions 4a1 and 4a2. Here, the upper left diagonal locking portion 4d of the locking member 4 is inserted into the upper pair of left diagonal slits 2c, the lower left diagonal locking portion 4f is inserted into the lower pair of left diagonal slits 2c, and the buckles of each other. It is fastened by the portions 4c and 4e, and the upper right diagonal locking portion 4h is inserted into the upper pair of right diagonal slits 2d, and the lower right diagonal locking portion 4j is inserted into the lower pair of right diagonal slits 2d. They are fastened with each other's buckle portions 4g and 4i.

As a result, the oblique locking portions 4d, 4f; 4h, 4j are inclined at a predetermined forward angle in the vertical direction C, for example, 30 °, and the left oblique slit 2c and the right oblique slit 2d are formed correspondingly. Therefore, the tension applied to the main body locking portion 4a2 when the care-requiring person M is lifted acts in the longitudinal direction of the elongated holes of the left diagonal slit 2c and the right diagonal slit 2d. Therefore, in particular, the connecting portion (a part of the support member 2) 2c1 between the pair of lower left diagonal slits 2c, the supporting member 2 near the left diagonal slit 2c, and the connecting portion between the lower pair of right diagonal slits 2d. (A part of the support member 2) It is possible to prevent the support member 2 in the vicinity of 2d1 and its right diagonal slit 2d from being deformed and damaged. In this way, the lifting force in the direction of deforming the support member 2 is less likely to act on the support member 2. The predetermined angle is preferably around 30 ° to 30 °, but is not limited to this.

According to the above body holding orthosis 1, since the support member 2 does not deviate from the predetermined positions of the back and waist of the care recipient M, the upper limbs of the care recipient M may be wet or the posture may be changed on the transfer device 10 described later. Even if it changes, the seating surface portion 20 of the transfer device 10 can stably stand up and sit down. For example, since the body holding orthosis 1 attached to the waist does not shift, the standing state can be maintained when standing up from the seat surface 20 of the transfer device 10, and the buttocks and the like can be washed, and clothes and undressing can be performed. It will be easy. Further, when the support member 2, the fixing member 3, and the locking member 4 are individually damaged or deteriorated, they can be easily replaced, and it is not necessary to replace the entire body holding orthosis 1, which is excellent in cost merit. Further, as will be described later, even if the body holding device 1 is lifted by the rotation operation of the rotation operation arm 18, the locking member 4 is not twisted, so that the sponge support member 2 is deformed. Damage can be suppressed. Further, even if it is used for the transfer operation of the care-requiring person M whose body is wet after taking a bath with the bathing device described later, it is possible to prevent the generation of mold and the like.

The transfer device 10 will be described with reference to FIGS. 6 to 12, including FIG. In the transfer device 10, each direction of front, back, left and right is set as shown in FIG. As shown in FIG. 5, each of these directions is a front-back, left-right direction when viewed from the care-requiring person M transferred by the transfer device 10.

With reference to these figures, the transfer device 10 has a carriage 11 and a device body 12. The bogie 11 has a pair of left and right bogie frames 14 having wheels 13 in the front and rear, a connecting frame 15 that connects both bogie frames 14 in the left-right direction, and a footrest plate 16.

The device main body 12 is integrally assembled with the carriage 11. The device main body 12 includes a pair of left and right grip levers 17, a pair of left and right rotation operation arms 18, a seat surface operation lever 19, a pair of left and right seat surface portions 20, a foot pad portion 21 for the care recipient M, and a caregiver N. It has a foot pad portion 30, a lock cover 26, a plurality of frames 22, and the like.

The caregiver N (see FIG. 5) controls the movement / stop of the transfer device 10 by using the grip lever 17, assists the care recipient M by using the rotation operation arm 18, and the seat surface operation lever. 19 can be used to control the standing / lodging behavior of the seating surface portion 20. In addition, the person requiring long-term care M can sit on the seat surface portion 20 or put his knees or shins on the foot pad portion 21. When the care-requiring person M seated on the seat surface 20 stands up, the foot pad 21 makes it easier to stand by the action of a so-called lever because at least a part of the knee or the shin hits the foot pad 21.

Further, the caregiver N can also rotate the rotation operation arm 18 from the front with at least a part of the knee or the shin touching the foot pad portion 30 for the caregiver N from the front of the transfer device 10. Therefore, even the caregiver N, who has weak strength such as a woman, can easily perform the rotation operation by applying force to the rotation operation arm 18, and the care recipient M can be easily erected from the seat surface portion 20.

As shown in FIG. 5, the foot pad portion 30 has a lower portion 30a in a lateral view protruding forward from the upper portion 30b when viewed from the caregiver N side. Therefore, in the case of a small caregiver, the knee position is lower than that of a large caregiver, but since the lower portion 30a of the foot pad portion 30 protrudes toward the caregiver, the petite caregiver has a foot pad. You can easily put your knees on the part 30. Further, in the case of a caregiver who can place the knee on the upper portion 30b, the rotation operation arm 18 can be operated in a posture in which the knee is bent with the portion below the knee along the front surface of the foot pad portion 30. it can. The foot pad portion 30 is made of an elastic material, preferably made of silicon rubber or molded by heat compression. As a result, the caregiver N can make it difficult to feel pain when the knee or shin is applied to the foot pad portion 30.

The rotation operation arm 18 is bent in the middle to serve as a rotation fulcrum, and one end side 181 is an operation end operated by the caregiver N, while the body holding device 1 is locked along the other end side 182. A plurality of locked metal fittings 40a to 40c capable of being locked are sequentially arranged. In FIG. 5, as shown in the enlarged view E2 of the portion where the dotted line portion E1 of the other end side 182 of the rotation operation arm 18 is viewed from the front, the plurality of locked metal fittings 40a to 40c are the rotation operation arm 18. The distance from the end of the other end side 182 increases as the distance increases. That is, at the initial position of the rotation operation arm 18 (see FIG. 9 described later), the locked metal fittings 40a to 40c become longer as the distance from the care recipient M increases.

Therefore, the locking metal fitting 5 of the body holding orthosis 1 is rotated according to the size of the physique of the care recipient M so that the main body locking portions 4a1 and 4a2 of the locking member 4 do not loosen in the middle. It can be easily and surely locked to any of the locked metal fittings 40a to 40c. That is, the larger the care-requiring person M is, the more the locking metal fitting 5 is attached to the locked metal fitting 40a on the front side (closer to the care-requiring person M). This is because the length of the body holding orthosis 1 does not change, so in the case of a large and well-worn care-requiring person M, the distance from the abdomen to the locked metal fittings 40a to 40c becomes short, and the position where the locking metal fitting 5 is attached This is because it becomes difficult to attach the locked metal fittings 40a to 40c unless the above is changed. Further, the lengths of the locked metal fittings 40a to 40c are changed, and this is related to the locked metal fitting 40c on the back side (the one away from the long-term care recipient M) with respect to the small long-term care recipient M. This is to prevent the locked metal fittings 40a and 40b in the foreground from getting in the way when the stopper metal 5 is attached.

The rotation operation arm 18 includes a grip portion 183 that the caregiver N grips for the rotation operation, and the tip 183a of the grip portion 183 is formed in a spherical shape. Therefore, the caregiver N can easily grip the rotation operation arm 18 and perform the rotation operation with force.

The device main body 12 is bent downward in a U shape and extends substantially vertically upward from the carriage 11, a pair of front left and right first main body frames 22 and a pair of rear left and right second main body frames 23 extending vertically upward from the connecting frame 15. A first connecting frame 24 that connects both first main body frames 22 to the left and right on the upper side, and a pair of upper and lower second and third connecting frames that connect the first and second main body frames 22 and 23 back and forth. It has frames 25a and 25b. The foot mounting plate 16 is provided over the lower portion of the first main body frame 22 and the connecting frame 15.

A pair of left and right rotation operating arms 18 will be further described with reference to FIGS. 7 and 8. In these figures, only a part of the rotation operation arm 18 on one side (left side in FIG. 6) is shown, but the same applies to the rotation operation arm 18 on the other side. Both rotation operation arms 18 are connected in parallel by a pair of connecting frames 18a and 18b (see FIG. 6 for the connecting frame 18b). In addition. The connecting frame 18b is a grip portion held by the care recipient M (see FIG. 5).

The rotation operation arm 18 has an arm plate 18c fixed to the lower end of the bend. Arm bolts 18d and 18e are fixed to the arm plate 18c, and the rotation operation arm 18 is pivotally attached to the frame plate 33 by the arm shaft 18f via the arm plate 18c. A tooth portion 18g is formed on the lower end side of the arm plate 18c.

A frame plate 33 is fixed to the first connecting frame 24. In the frame plate 33, the upper end side thereof is located between the arm bolts 18d and 18e, and the support shaft 33b of the ratchet claw portion 33a is pivotally supported by the frame plate 33. The ratchet claw portion 33a is urged by a tension coil spring 33c in a direction in which it meshes with the tooth portion 18g of the arm plate 18c of the rotation operation arm 18.

The tooth portion 18g provided on the arm plate 18c of the rotation operation arm 18 and the ratchet claw portion 33a that mesh with the tooth portion 18g are at predetermined positions where the rotation operation arm 18 is rotated from the initial position described later. Configure a locking mechanism to lock. A protective cover 26 (see FIG. 5) is provided to cover a portion constituting the lock mechanism.

Locking and unlocking of the rotation operation arm 18 in the lock mechanism will be described with reference to FIGS. 9 and 10. 10 (a) to 10 (c) are views of main parts corresponding to the initial position, the lock position, and the unlock position of the rotation operation arm 18 shown in FIG. That is, FIG. 10A is a view of a main part of FIG. 9 when the rotation operation arm 18 is in the initial position, and FIG. 10B is a view of FIG. 9 when the rotation operation arm 18 is in the locked position. 10 (c) is a view of the main part of FIG. 9 when the rotation operation arm 18 is in the unlocked position.
