DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nursing stick used by elderly people requiring nursing who have weak walking ability to assist their walking.

[0002]

2. Description of the Related Art In a nursing home or the like, an elderly in need of walking who has weak walking ability supplements the walking force by pressing a walking stick obliquely backward during walking. As shown in FIG. 15, the conventional nursing stick S ′ includes an elongated rod-shaped main body B ′ and a grip G ′ attached to the upper end thereof, including a general-purpose cane. The grip portion G 'has a structure integrally attached to an upper end portion of the main body portion B'.

[0005] As shown in FIG. 15, an elderly man M, whose walking ability is weak, arranges almost the entire cane S ′ behind the body in a slightly forward leaning posture, and places the cane S ′. Is pressed backwards to compensate for the walking force by the reaction force received from the ground contact surface. However, in the conventional nursing stick S ′, since the grip portion G ′ is integrated with the main body portion B ′, the cane S ′ takes a forward tilted posture, so that the grip portion G ′ similarly moves forward. In order to adopt the inclined posture, it is necessary to slightly incline the arm A and the wrist of the user of the cane S '. For this reason, the arm A and the wrist become cramped, and the pressing force F ′ thereof is smaller than that in the case where the arm is pressed from vertically upward to immediately below, and the walking supplementary force by the walking stick S ′ is also small.

[0004] As the aging society progresses, the necessity of a nursing stick increases more than ever, and the main body B 'described above is used.
It is also desired to improve the conventional nursing stick with the grip portion G ′ integrated with the nursing stick.
