DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a walking assist device which can be used both for assisting a person with a walking disorder and for an elderly person.

[0002]

2. Description of the Related Art For example, people with walking disorders and elderly people
When walking without the assistance of a caregiver, a walking assist device (hereinafter, a four-wheeled walking vehicle) provided with a seat plate so as to be able to sit on the way is often used. This four-wheeled walking vehicle 1
Basically, four wheels 2, a pipe frame 3, and a seat plate 4
And a grip 5 for the user to grasp and grasp on the pipe frame 3 protruding above the seat plate 4,
As shown in FIG. 6, FIG. 7, and FIG. 8, this type is used by a person having a walking disorder, for example, a person with illness, a person who needs support and a person with a degree of nursing care (1), etc. And FIGS. 9, 10 and 11 show a type used by the elderly. As is well known, when a person walks, he repeatedly performs the operation of lifting the other foot with one foot as an axis and stepping forward, and then stepping on the one foot that was the axial foot with the other foot that has been stepped on as an axis. However, in the case of the above-mentioned sick person, his or her legs are weak, so when stepping on one foot, the balance between the right and left is easily lost. For this purpose, a four-wheeled walking vehicle 1 shown in FIG. 6 in which the grip 5 is directed in the traveling direction is used. On the other hand, in the case of elderly people, since the waist is often bent, it is considered necessary to balance the trunk in the front-back direction, and the grip 5 moves in the traveling direction as in the four-wheeled walking vehicle 1 shown in FIG. Are used so as to intersect with.

[0003]

Therefore, the manufacturing or selling side must prepare for the production of both types of the four-wheeled walking vehicle 1 described above, which may cause wasteful inventory. The present invention has been proposed from such a background, as a walking aid for people with walking disorders,
It is another object of the present invention to provide a walking aid that can be used for the elderly.

[0004]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a walking aid according to the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an upper side of a four-wheeled walking vehicle 10 which is a walking aid. The walking assist device 10 has basically the same structure as the four-wheeled walking vehicle 1 shown in FIGS. In such a four-wheeled walking vehicle 10, a grip pipe 13 having a middle portion bent by a predetermined angle is attached to the tip of a pipe frame 12 projecting upward on both sides of a seat plate 11 so that the tip end is directed substantially horizontally. I have. This grip pipe 13
A grip 14 made of, for example, a soft synthetic resin is provided on the front end side of the head to make it easy for the user to grasp. In the vicinity of the end of the pipe frame 12, a knob bolt 16, which will be described later and constitutes a fixing means 15 for selectively fixing the grip pipe 13 in a predetermined direction, is provided.

Therefore, the fixing means 15 will be described.
As shown in FIG. 2, the fixing means 15 is
Knob bolt 16 provided near the tip and grip pipe 1
3 and a plurality of narrowed portions 17 provided at positions where they can be freely inserted into and retracted from the pipe frame 12. The knob bolt 16 is screwed into an embedded nut 18 integrally planted near the tip of the pipe frame 12 so that the tip of the bolt enters the pipe frame 12.
The squeezed portion 17 is formed by drawing an outer diameter of a predetermined width so as to be smaller than the outer diameter of the grip pipe 13, and a plurality of squeezed portions 17 are provided at appropriate intervals (see FIG. 3). The tip of the knob bolt 16 that enters the pipe frame 12 abuts on one of the narrowed portions 17 to hold the grip pipe 13 so as not to shift in the axial direction.

[0007] The constricted portion 17 is formed with two concave portions 19 as rotation stoppers for fixing the grip pipe 13 at a predetermined position so as not to rotate around the axis. In these recesses 19, the knob bolt 1
6 has a structure in which the grip pipe 13 is fixed so that the grip pipe 13 does not move around the axis by abutting the tips. In this case, the concave portions 19 are formed so as to form an angle of 45 ° with each other as shown in the cross-sectional view of the narrowed portion 17 (see FIGS. 4 and 5).

In the above-described four-wheeled walking vehicle 10, when a person who is ill or who has a decrease in muscular strength of both lower limbs such as a person who needs support and a person who needs nursing care (1) is used, a grip pipe is used. The grip 14 at the distal end of the vehicle 13 is directed in the traveling direction of the four-wheeled walking vehicle 10. On the other hand, when used by the elderly, the grip 14 at the tip of the grip pipe 13 is directed in a direction orthogonal to the traveling direction of the four-wheeled walking vehicle 10. For that purpose, first, the knob bolt 1
In a state where 6 is loose, that is, in a state where the tip of the knob bolt 16 does not enter the inside of the pipe frame 12, the grip pipe 13 is inserted from the tip of the pipe frame 12 so that the grip 14 can be easily gripped. .
At this point, the knob bolt 16 is screwed into the suitable narrowed portion 17, and the tip of the knob bolt 16 abuts on the narrowed portion 17 to hold the grip pipe 13 so as not to shift in the axial direction. Next, the grip pipe 13 is set by the user.
When the grip pipe 13 is turned around the axis so that the tip grip 14 is directed in the traveling direction of the four-wheeled walking vehicle 10 or in the direction orthogonal to the traveling direction of the four-wheeled walking vehicle 10. The concave portion 19 formed in the narrowed portion 17 is provided at the position of the tip of the knob bolt 16, and if the knob bolt 16 is further screwed in, the distal end of the knob bolt 16 presses and contacts the concave portion 19, so that it does not move around the axis. Thus, the grip pipe 13 can be restrained.

As described above, the fixing means 15 is provided by the user.
The knob pipe 16 can adjust and fix the grip pipe 13 in an easy-to-use height and in an easy-to-use direction, so that it can be adapted to the user's body shape, and as in the past, four wheels different for each user It is not necessary to prepare the walking vehicle 10, and the equipment cost can be reduced.

[0010]

As described above, according to the present invention, the grip pipe can be adjusted and fixed in an easy-to-use height and an easy-to-use direction, so that it can be widely adapted to the user's body shape. It is not necessary to prepare different walking aids for each user as in the above, and the equipment cost can be reduced.
