Description

  The present invention relates to a bathroom shower chair that can wash or bathe the body in a sitting position, and more specifically, can tilt a seat surface part and a backrest part in a front-rear direction while maintaining a sitting position. The present invention relates to a mobile nursing shower chair equipped with a reclining mechanism that can be fixed at an arbitrary tilt angle.

  Care shower chairs were developed mainly for people with physical disabilities (such as handicapped people who need care) and elderly people. It is made so that the body can be washed or bathed. Most of the conventional shower chairs for nursing care are pipe-chair type, and the structure is also that the legs are attached to the seat surface part and the handle pipe is attached with a fixed or flip-up handrail or armrest, etc. It is. For example, Patent Document 1 has a structure in which four legs are attached to a seat pipe, a fixed or openable handrail is attached between the seat pipe and the handle pipe, and a seat surface seat is fixed to the seat pipe. The seat surface seat is a fixed chair type with a groove for facilitating washing of the local part, and the seat surface seat portion can be rotated 360 degrees as a turntable system and in any orientation A rotary chair type having a function capable of being freely fixed is disclosed. Further, Patent Document 2 has a two-part structure in which the seat surface is divided into left and right at the center so that the local part can be washed from the front and back of the seat surface, and the backrest so that the back can be washed while sitting down. There is disclosed a nursing care shower chair that is attached to a handle pipe so as to be pivotable in the front-rear direction by a shaft pin, and is further movable by attaching casters to front legs and rear legs.

Reference numeral 2-4 denotes a connecting rod which is provided between the left and right adjustment guide plates 2-1.

  The seat pipe 3 supported and fixed to the seat surface receiver 2 is integrated with the handle pipe 4, and the seat pipe 3 portion is connected to the reclining receiving member 2-2 of the seat surface receiver 2 via a reinforcing member 3-1. The shaft pipe 3-1a is pivotally mounted in the front-rear direction so that the seat pipe 3 can tilt in the front-rear direction with the shaft pin 3-1a as a fulcrum. The reinforcing member 3-1 is fixed to the inner side surface of the seat pipe 3 with screws or the like. 3-2 is a seat surface sheet, and is fixed to the seat pipe 3 with screws.

  The reclining mechanism 5 provided on the back surface of the chair body is laterally connected via a handrail attachment member 6-1 between the connecting member 5-3 horizontally provided at the rear end portion of the reclining receiving member 2-2 and the handle pipe 4. A reclining spring cylinder 5-1 disposed between the connecting member 5-4 provided in the vertical direction, and a manual lock pin mechanism 5-2 for fixing the seat pipe 3 and the handle pipe 4 to a desired tilt angle. It consists of and. The reclining spring cylinder 5-1 is a double-pipe cylinder composed of an outer cylinder 5-1a and an inner cylinder (expandable cylinder) 5-1b, and the reclining spring 5 housed in the outer cylinder 5-1a. -1c is a mechanism in which the inner cylinder 5-1b is slidably supported and moves forward and backward. The manual lock pin mechanism 5-2 incorporated in the reclining spring cylinder 5-1 includes a lock pin The lock pin 5-2c, which is given an outward pressing force to the guide 5-2a by the spring 5-2b, is housed and fixed in the inner cylinder 5-1b of the reclining spring cylinder 5-1, and the reclining spring. The lock pin 5-2c can be projected and retracted in a plurality of lock pin holes 5-2d formed at desired intervals in the axial direction on the side surface of the outer cylinder 5-1a of the cylinder 5, so that the reclining bar A lock pin pressing projection 5-2h attached to a lock bracket 5-2e slidably fitted on the outer cylinder 5-1a of the cylinder 5 so as to be pivotable in the vertical direction by a shaft pin 5-2f. The seat pipe 3 and the handle pipe 4 are reclined by the attached reclining lever 5-2g. The reclining spring cylinder 5-1 is a method in which the inner cylinder (expandable cylinder) 5-1b moves steplessly. Therefore, in the present invention, the inner cylinder (expandable cylinder) is formed by the lock pin mechanism 5-2. A method of intermittently operating 5-1b was adopted.

The lock lever is locked by being positioned directly below the connection member 6-2, and the lock is released by rotating the lever laterally. This flip-up handrail is known.

  In the care shower chair having the above structure, in the non-reclining state, as shown in FIG. 1, the handle pipe 4 and the seat pipe 3 are fixed at an ordinary backrest angle by the reclining spring cylinder 5-1, and The seat pipe 3 constituting the surface is held in a substantially horizontal state. When reclining in this state, the caregiver pulls the reclining lever 5-2g with the lock pin pressing projection 5-2h upward, and the lock pin 5-2c is moved to the inner cylinder 5- by the lock pin pressing projection 5-2h. The handle pipe 4 and seat pipe 3 are tilted backward with the shaft pin 3-1a as a fulcrum, and the lock pin 5-2c is moved into the lock pin hole 5-2d at a predetermined tilt position. Insert and lock. By this operation, the handle pipe 4 and the seat pipe 3 are reclined to a predetermined tilt angle as shown in FIG.

  During the reclining operation, the handle pipe 4 and the seat pipe 3 tilt in the front-rear direction while maintaining the sitting posture, so that the seated posture of the user who is on board is fixed and no forward shift occurs. In addition, the sitting posture at the time of reclining can take a comfortable posture without feeling any pressure or pain in the abdomen. In addition, since the entire body can be washed while maintaining a sitting posture, the burden and fatigue on the caregiver are significantly reduced.

  When the inclination angle between the seat pipe 3 and the handle pipe 4 is changed, the same operation as described above, that is, the reclining lever 5-2g with the lock pin pressing projection 5-2h is pulled up to release the lock, The pipe 3 and the handle pipe 4 are tilted at a predetermined angle, and the lock pin 5-2c is fitted into the lock pin hole 5-2d and locked at a predetermined tilt position.

  Also, when returning the seat pipe 3 and the handle pipe 4 from the reclining state to the original non-reclining state, the reclining lever 5-2g is pulled up and the lock pin pressing projection 5-2h is used to lock the lock pin 5- The lock may be released by pushing 2c into the inner cylinder 5-1b. When the lock is released, the inner cylinder (expandable cylinder) 5-1b moves forward by the action of the reclining spring cylinder 5-1, so that the seat pipe 3 integrated with the handle pipe 4 supports the shaft pin 3-1a. And is held in the original non-reclining state by the lock mechanism.

  In the care shower chair having the above structure, when changing the height of the seating surface, as described above, the engaging pin screw 2-3 attached to the reclining receiving member 2-2 is loosened and the seat pipe 3 and The handle pipe 4 may be moved up and down, the height adjusting engagement groove 2-1a of the adjustment guide plate 2-1 is selected, and the engagement pin screw 2-3 is engaged and tightened.
