Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> This invention is a walking method that assists walking of patients, children, the elderly, etc. (referred to as "patients" in this specification) so that they do not fall. The present invention relates to an auxiliary device, and more particularly, to an improvement of a type in which a frame portion is foldable.

<Prior Art> A conventional example of the walking aid 1 is shown in FIGS.

This walking aid 1 is composed of a body support portion 3 and a frame portion 10.

The body support portion 3 is composed of a U-shaped grip portion 5 and a tubular mounting portion 7 that a patient or the like can hold.

The frame portion 10 is attached to a U-shaped lower frame 13, a front frame 15 attached to a front edge of the lower frame 13 so as to be tiltable in the front-rear direction, and a rear end of the lower frame 13 so as to be tiltable in the front-rear direction. And its upper end is composed of a rear frame 17 that intersects with the front frame 15. The portion of the lower frame 13 to which the castor 11 is attached is carried by the extended portions of the front and rear frames 15 and 17, respectively.

Then, the connecting rod 19 inserted into the free end of the front frame 15 is inserted into the attachment portion 7 of the body supporting portion 3 and the screw 8 is tightened to tighten the body supporting portion 3 and the frame portion 10.
And are connected.

Reference numeral 21 is a screw that connects the front frame 15 and the rear frame 17, reference numeral 23 is a bearing that pivotally supports the front frame 15,
Reference numeral 25 is a pin that pivotally attaches the rear frame 17 to the lower frame 13.

The walking aid 1 having such a configuration is folded as follows during transportation or storage.

First, the screws 8 are loosened to move the frame 10 to the body support 3
Pull out. Then, by removing the screw 21, the front frame 15 and the rear frame 17 are separated. As a result, the front and rear frames 15 and 17 can be tilted forward and backward with respect to the lower frame, and can be folded as shown in FIG.

<Problems to be Solved by the Invention> However, in the conventional walking aid 1, since the body support portion 3 and the frame portion 10 are separated when folded, the handling is inconvenient.

Further, in response to the request to attach the brake lever of the caster 11 to the body support portion 3, in the structure in which the body support portion 3 is removed from the frame portion 10 as described above, the brake wire must be unnecessarily lengthened. Then, there arises a problem that the mounting becomes difficult.

<Means for Solving the Problems> The present invention has been made in view of the above problems, and the structure thereof is such that a body support part for holding a patient or the like and a lower frame to which casters are attached are provided on the front side thereof. A front frame that is tiltably attached in the front-rear direction, and a rear frame that is tiltably attached in the front-rear direction on the rear side of the lower frame,
In a foldable walking assist device comprising a frame part composed of connecting means for connecting the upper ends of the front frame and the rear frame, a body supporting part is provided to an upper edge of the frame part and to the frame part. It is characterized in that it is attached so as to be tiltable in the front-back direction.

<Example> Hereinafter, the present invention will be described in more detail with reference to an example.

The walking aid 30 of the embodiment includes a body support portion 33, a frame portion 40, a tilting mechanism 60, and a brake device 80.

The body support portion 33 includes a substantially U-shaped body portion 34 and covers 35 attached to both side portions thereof. Of course, as the body support portion 33, the one shown in the conventional example can be used.

The frame portion 40 is an assembly of a lower frame 43, a front frame 45 and a rear frame 51. The lower frame 43 is a U-shaped member and has a reinforcing frame 44 on the front side.
Is provided. Four casters 41 are arranged on the lower frame 43.

The front frame 45 includes a pair of pipes 45a and 45b. Collar 4 is attached to the lower end of each pipe 45a and 45b.
6 are connected. This collar 46 is a reinforcement pipe 44
Is loosely fitted to. As a result, the front frame 45 can be tilted in the front-rear direction with respect to the lower frame 43. A collar 47 is vertically attached to the upper ends of the pipes 45a and 45b. The collar 47 has a tilting mechanism 60.
The rod 68 is inserted and the height is adjusted by the knob 48.

The pair of pipes 45a and 45b are connected by a substantially H-shaped slider 49. The upper ends of pipes 51a and 51b forming the rear frame 51 are connected to both ends of the slider 49. On the other hand, the lower ends of the pipes 51a and 51b are pivotally attached to the rear edge of the lower frame 43 (by pins). The slider 49 is fixed to the pipes 45a and 45b of the front frame 45 by tightening the knob 53 attached to the slider 49. That is, the slider 49 and the knob 53 serve as a connecting means for the front frame 45 and the rear frame 51.

The tilting mechanism 60 will be described with reference to FIGS.

The tilting mechanism 60 of the embodiment includes a rail 61 fixed to the body supporting portion 33, a guide screw 65 inserted into a groove 63 of the rail 61, a knob 67 screwed into the screw 65, and a knob 6.
7 and a retainer 69 sandwiching the rail 61. A rod 68 is provided downward from the retainer 69,
The rod 68 is inserted into the collar 47 of the front frame 45.

In the tilting mechanism 60 having the above structure, the rail 61 can be moved relative to the screw 65 by loosening the knob 67. Since the rail 61 is bent in a substantially V shape, the angle of the body support portion 33 with respect to the collar 47, that is, the frame portion 40 changes depending on the position of the screw 65 with respect to the rail 61.

5 and 6 show a tilting mechanism 70 of another mode. The same members as those shown in FIGS. 3 and 4 are designated by the same reference numerals.

This tilting mechanism 70 connects the retainer 69 and the body support portion 33 with a pair of links 71 and 72.
In addition, the body support portion 33 straddles the screw 65, and the knob 67
A clamped plate 73 that is sandwiched between the retainer 69 and the retainer 69 is attached.

The brake device 80 includes a shoe 81, a brake wire 83, and a lever 85. As shown in FIG. 7, the shoe 81 presses against the peripheral surface of the caster 11 and stops its rotation. The lever 85 is attached below the front of the body support portion 33.

Next, a mode of folding the walking aid 30 of the embodiment will be described (see FIGS. 8 to 11).

First, the knob 48 is loosened to lower the body support portion 33 (8th
See figure). Then, the knob 53 is loosened to free the slider 49. In this state, when a downward load is applied to the body support portion 33 (see FIG. 9), the slider 49 automatically slides down the front frame 45, and the front and rear frames 45 and 51.
Is folded. Both frames 45 and 51 are lower frames 43
Parallel to (ie, completely folded; 10th
The body support portion 33 is rotated counterclockwise in the drawing by the tilting mechanism 60 so as to be parallel to the folded frame portion 40 (see FIG. 11).

On the other hand, in order to assemble the walking assist device 30, the above work is reversed.

<Operation and Effect of Device> As described above, in the walking assist device of the present invention, the body support portion tilts in the front-back direction with respect to the frame. Therefore, when the frame is folded, it is possible to make them parallel by changing the angle of the body support with respect to the frame.

Therefore, the walking aid can be entirely folded without removing any body support from the frame.

Also, because the body support is not removed from the frame,
A brake device or the like can be easily attached to the body support portion.
