As shown in FIG. 1, the front wheel portions 130 connected to the two front wheel frames 111 are formed of two wheels, and are arranged to be able to rotate 360 degrees. Therefore, the front wheel section 130 can be directed in a direction in which the elderly person to use wants to proceed. The rear wheel portions 140 provided on the two rear wheel frames 112 are single wheels. As shown in FIG. 5, the distance between the two front wheel portions 130 and the outer wheels is, for example, 440 mm, and the distance between the two front wheel frames 111 is as shown in FIG. Is
It is 338 mm.

The distance in the width direction of the walker 100 is smaller than the distance in the width direction of the conventional walker, and the size of the walker 100 is reduced. Therefore, even if the elderly used go shopping in a supermarket or the like, it is possible to prevent the walker 100 from hitting a product or the like in a passage or the like. In particular, the distance between the two front wheel frames 111 is significantly reduced. When the handle is provided with the same width on the two narrow front wheel frames 111, the width of the handle also becomes narrower, and the width of the handle becomes narrower than the shoulder width of the elderly to be used, resulting in a hard-to-use walker. I will.
However, in the present embodiment, as shown in FIG. 5, the handle 150 is connected to the two front wheel frames 111, and the grip 151 of the handle 150 is provided.
Are formed to protrude outward in the width direction. Specifically, it protrudes as shown in FIG. FIG. 6 is a schematic enlarged view showing a part of the handle part 150. As shown in FIG. 6, the support portion 152 of the handle portion 150 is bent outward at an angle θ from a portion connected to the front wheel frame 111. Is, for example, 19 degrees.

[0035] At the boundary with the grip portion 151 provided in connection with the support portion 152, it is bent inward. 5 and FIG. 6, which is the outermost portion of the handle portion 150, is arranged inside the wheel outside the front wheel portion 130. That is, the entire width of the grip portion 151 of the handle portion 150 in FIG. 5 is smaller than 440 mm, which is the distance between the two front wheel portions 130 and the outer wheels. Accordingly, the entire width of the grip portion 151 of the handle portion 150 is formed to be wider than 338 mm, which is the distance between the two front wheel frames 111, so that it does not become smaller than the shoulder width of the elderly to be used. Grip part 151
It is easier to grasp with the arms open naturally. For this reason, the small walker 10 having the handle portion 150 that is easy for the elderly to grasp, and in which the width of the two front wheel frames 111 is small.
It becomes 0.

The grip 15 of the handle 150
5 is shorter than the distance between the two front wheels 130 and the outer wheels, respectively, so that the handle 15
0 does not protrude outward from the front wheel portion 130, and the handle portion 150 does not unnecessarily protrude in the width direction and does not hinder operation.

In this embodiment, the handle 15
Although the total width of 0 is, for example, 404 mm, the total width may be 440 mm, and may be the same as the distance between the two front wheels 130 and the outer wheels. In this case, the length of the grip 151 of the handle 150 can be set to the maximum length that does not hinder the operation, so that the handle 150 can be easily gripped by the elderly.

By the way, as shown in FIG. 6, the top of the grip 151 of the handle 150 is curved so that the center thereof protrudes. That is, the R at the top of the grip 151 is, for example, R2000. Since the top of the grip portion 151 has a gentle curve as described above, when the elderly person grips the handle portion 150, the elderly person can grip the elbow or the like without tension. In addition, a gentle curve makes it easy to grip any part. For this reason, an elderly person with a narrow shoulder can grasp near the center of the grip portion 151, and an elderly person with a wide shoulder can grasp both ends. In the present embodiment, the shape of the handle is particularly curved so as to make it easier to grasp the vicinity of both ends, but the shape of the handle may be inclined at an approximate angle. Further, the handle 150
The cross-section (cross-sectional shape formed along the traveling direction of the walker 100) of the grip portion 151 is substantially elliptical as shown in FIG. The outside of the grip portion 151 is formed of elastic urethane foam 151a, and a core portion 151b is formed inside the grip portion 151.

Accordingly, while the rigidity of the handle portion 150 is ensured by the core portion 151b, the elastic urethane foam 151 is disposed in a portion outside the elderly person's grip. For this reason, the elderly hold the palm 1
Even if the user presses the walker 100 while holding the grip 51, the grip 15
1 can receive the power softly. The long axis of the grip 151 is arranged in the X-axis direction shown in FIG. 2 and the short axis of the grip 151 is arranged in the Y-axis direction in FIG. Frame 111
Of FIG. 2 (12 degrees).

Therefore, when the elderly person pushes the grip portion 151 of the handle portion 150 to push the walker 100,
As shown in FIG. 2, the relatively wide surface formed by the long axis of the grip 151 can just abut the elderly person's palm without difficulty, so that the elbow or wrist may have an unnatural shape. Absent. For this reason, even when the walker 100 is pushed with the user's weight applied for a long time, the fatigue of the elderly can be reduced.

In the present embodiment, the cross-sectional shape of the grip portion 151 is configured as shown in FIG. 7, but may be configured as shown in FIG. 8 instead. That is, in the center of the grip portion 251, the core portion 2 formed in a U-shape is formed.
51b is arranged, and the urethane foam 251a is arranged outside thereof. With this configuration, the core 25
1b has two projections, so that even if an elderly person grips the part of the urethane foam 251a, the urethane foam 251a
Can be prevented from turning around the core 251b.

As shown in FIGS. 3 and 5, a brake lever 170 is disposed along the grip 151 of the handle 150. This brake lever 17
0, when the elderly person puts his / her finger or the like and pulls in the direction of the grip portion 151, the brake shoe 190 provided on the rear wheel portion 140 via the wire 180 shown in FIG. It is supposed to work.

The brake lever 170 functioning in this manner
Is formed so as to correspond to the entire width of a region of the grip portion 151 of the handle portion 150 that can be gripped by the user.
Therefore, the elderly can grasp the grip 151 of the handle 150.
, The brake lever 170 can be quickly operated and the walker 100 can be safely stopped. The brake lever 170 is provided with a brake engagement hook 191 provided on the grip portion 151.
By engaging (see FIG. 1), the operating state of the brake can be maintained, and it is possible to effectively prevent the walker 100 from starting to move against the will of the elderly. Further, similarly to the grip portion 151 of the handle portion 150, the brake lever 170 is protruded outward so that the grip portion 151 is formed.
When the user has the same width as that shown in FIG. 5 (see FIG. 5), even if the user does not hold the grip portion 151 and uses it with the grip portion 151 put on the hand, the operation of the brake lever 170 is promptly handled. it can.

By the way, the handle 151 as described above
Is connected to the front wheel frame 111 by inserting a cylindrical handle base 153 into the pipe of the front wheel frame 111 as shown in FIG. By adjusting the depth of the handle base 153 inserted into the front wheel frame 111, the height of the handle portion 150 can be freely changed in accordance with the height of the elderly used. FIG. 9 is an enlarged perspective view showing a connecting portion between the handle base 153 and the front wheel frame 111.
As shown in FIG. 9, the handle base 153 is inserted into the front wheel frame 111, and is a height adjuster serving as an adjuster so as to cover a connecting portion between the handle base 153 and the front wheel frame 111. 300 are arranged. The height adjusting section 300 has a pipe cover 310 that covers a connecting portion between the handle base 153 and the front wheel frame 111 while maintaining a certain gap. In addition, the pipe cover 310 has a fixed knob 320 for eliminating a certain gap held by the pipe cover 310 and causing the pipe cover 310 to act to tighten the connecting portion.

More specifically, as shown in FIG. 9, two projecting pieces 31 protruding from the pipe cover 310 are formed.
By moving 1 by the fixing knob 320, the connecting portion is tightened or opened. That is, when the fixing knob 320 is moved downward along the arrow direction shown in FIG. 9, the two protruding pieces 311 move in the approaching direction,
The connecting part is tightened. Conversely, when the fixing knob 320 is moved upward in the direction of the arrow, the two protrusions 3
11 move in a direction away from each other to open the connecting portion. Therefore, when the elderly to use wants to increase the height of the handle part 150, first, FIG.
Is moved upward to open the projection 311 of the pipe cover 310. Then, the handle base 153 is pulled up by a necessary length.
Further, when the desired length is reached for the elderly, the fixing knob 320 is moved downward so that the pipe cover 310 tightens the front wheel frame 111 and the handle base 153. Thus, the relative positional relationship between the front wheel frame 111 and the handle base 153 is fixed. In addition, since the height of the handle 150 can be adjusted steplessly as described above, the height of the handle 150 can be accurately adjusted according to the height of each elderly person.

Further, as shown in FIG. 9, the height adjusting section 300 includes a fixing screw 330. As shown in FIG. 9, the fixing screw 330 is provided with a round hole provided in the front wheel frame 111 so as to be insertable and a handle base 15.
3 penetrates a vertically long hole 153a provided to the other end. Therefore, even if the elderly accidentally pulls the handle base 153 extremely high upward from the front wheel frame 111, it is possible to effectively prevent the handle base 153 from falling out of the front wheel frame 111 and falling off. Can be. The height of the handle 150 can be adjusted, for example, by about 100 mm as shown in FIG.
