Description

Activity aid chair

The present invention relates to an auxiliary chair, and more particularly to an activity auxiliary chair that can be slid and positioned.

For people with reduced mobility or the elderly, because they can't easily enter the bathtub as the average person can bathe, they must rely on the assistance of the bathing aids and the caregiver to complete the bath.

As shown in FIG. 1 , the conventional auxiliary device 9 for bathing includes a seat portion 91 , two horizontal tubes 92 spaced apart and having two positioning holes 921 , and two sliding plates can be slid and fixed relative to the horizontal tubes 92 . A movable sleeve 93 (only one of which is shown) on both sides of the bottom surface of the seat portion 91, two elastic units mounted in one of the horizontal tubes 93, and two coupled to both sides of the horizontal tubes 92 and respectively supported On the ground R and the stand 920 in the bathtub B. Each of the elastic units has a positioning button 94 that is elastically inserted into a positioning hole 921. One of the movable sleeves 93 has a through hole 931 opposite to any of the positioning holes 921 and the positioning button 94 is elastically extended. Accordingly, the positioning button 94 is simultaneously inserted into the positioning hole 921 and the through hole 931 to provide positioning of the seat portion 91. Further, the operator presses the positioning button 94 with a finger to release the positioning button 94 from the through hole 931. The seat portion 91 can be slid.

As described above, the auxiliary device 9 has a function of positioning and sliding the seat portion 91, but is operated (for example, the seat portion 91 is moved from the outside of the bathtub B toward the inside of the bathtub B). Since the operator must directly press the positioning button 94 located outside the bathtub B with a finger to slide the movable sleeve 93, however, the perforation 921 generally does not allow the finger to protrude and the movable sleeve 93 has a certain thickness or the like. The factor often causes the operation of the positioning button 94 to be released from the punctured state of the perforation 921 when the positioning button 94 is pressed. Moreover, when the movable sleeve 93 is slidably close to the positioning button 94 of the bathtub B, the operator must press the positioning button 94 located in the bathtub B to allow the movable sleeve 93 to pass the positioning button 94, thereby The through hole 931 is opposite to the positioning hole 921 for the positioning button 94 to elastically protrude into the positioning hole 921 and the through hole 931. However, in the case of inadvertent attention, the operator's finger can easily be released without being released. The movable sleeve 93 hits, so the safety in use is still insufficient.

Accordingly, it is an object of the present invention to provide an activity assisting chair that enhances the convenience and safety of operation.

Therefore, the new activity auxiliary chair comprises a supporting unit, a riding unit and an actuating device.
