Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rehabilitation alternating walker used by sick people in the process of recovery to practice walking.

[Conventional technology]

2. Description of the Related Art Conventionally, an alternating walking vehicle is known in which left and right frames are pivotally connected by a connecting frame member so that the left and right frames can move forward alternately. Furthermore, a fixed walking vehicle is also known in which the left and right frames are fixedly connected by a connecting frame member so that the walking vehicle can move straight forward.

[The problem that the idea aims to solve]

By the way, conventionally, an alternating walker that can move forward alternately was used for initial walking training, and once the patient had recovered to a certain level of ability to walk, a fixed walker was used for rehabilitation, depending on the patient's recovery status. Therefore, I decided to use a pedestrian vehicle depending on the situation.

For this reason, hospitals and the like must keep two types of walking vehicles on hand, which requires a large amount of investment and also poses problems in that it involves a large administrative burden.

The present invention has been made in view of the problems of the prior art, and its purpose is to provide an alternating walking vehicle that can be used as a fixed walking vehicle by one-touch operation. It is.

[Means to solve the problem]

In order to achieve the above object, the present invention provides an alternating walking vehicle configured such that a right side frame and a left side frame each having casters at the lower end are pivotally connected by a connecting frame member so that the left and right frames can move forward alternately. wherein the right side frame and the left side frame are rotatably provided with a locking fitting having a locked portion, and the connecting frame member is fixedly provided with a locking portion to which the locked portion is locked, Rotating the locking fitting to lock the locked portion to the locking portion allows the left and right frames and the connecting frame member to be held in a fixed state.

[Effect]

The alternating walking vehicle configured as described above is connected to the left and right frames by rotating the locking fittings provided on the left and right frames and locking the locked parts to the locking parts of the connecting frame member. The frame member is held in a fixed state so that it can be used as a fixed walking vehicle that can move straight forward. Then, from this state, by rotating the locking metal fitting to release the lock between the locked part and the locked part, the left and right frames can move forward alternately, and can be used as an alternating walking vehicle.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 and 1 are a pair of right and left frames, and these left and right frames 1,
1 has a front leg part 3 and a rear leg part 4 in front and behind a horizontal grip part 2.
It is formed into a shape when viewed from the side by hanging it vertically.
Casters 5 and 6 are attached to the lower ends of the front leg section 3 and the rear leg section 4, respectively. Reference numeral 7 designates a connecting frame member in which two upright short pipes 8, 8 are connected by horizontal rods 9, 9 at two locations above and below, and both of the short pipes 8, 8 are connected to each front leg portion 3 of the left and right frames 1, 1. , 3 at predetermined height positions, the left and right frames 1, 1 are pivotally connected so as to be able to move forward alternately as shown by chain lines in FIG.

Reference numeral 10 denotes a bar that regulates the maximum pitch of the alternate forward movement of the left and right frames 1, 1, and the left and right ends bent horizontally backward are brought to positions closer to the front of the gripping parts 2, 2 via support shafts 11, 11. Install with pivot support. As shown by the chain line in FIG. 4, the bent portion comes into contact with the front bent portions of the left and right frames 1, 1, thereby regulating the forward pitch and functioning as a stopper. 12,
Reference numeral 12 denotes a reinforcing arm installed between the front leg section 3 and the rear leg section 4 in parallel to the gripping sections 2, 2 of the left and right frames 1, 1.

However, in the present invention, the reinforcing arm 12,
Support shafts 13, 13 are provided at the front position of 12 and protrude downward, and plate-shaped latching fittings 1 are attached to these support shafts 13, 13.
4 and 14 are pivotably supported for horizontal rotation. These latching fittings 14, 14 are provided with locked parts 15, 15 made of circular arc notches, and further have a knob 1 at the tip.
6 and 16 are integrally formed. On the other hand, locking portions 17, 17, to which the locked portions 15, 15 are locked, are fixedly provided at both left and right end portions of the horizontal rod 9 located at the top of the connecting frame member 7. This locking part 1
7 and 17 are metal rods bent into an L shape as shown in the figure.

Since the present invention is constructed as described above, as shown in FIG.
By rotating the left and right frames 1, 1 to a position where they are not locked, the left and right frames 1, 1 can be used as an alternating walking vehicle that can move forward alternately.

Then, as shown in FIG. 3, if the locking fittings 14, 14 are rotated to lock the locked parts 15, 15 of the locking parts 15, 15 to the locking parts 17, 17 of the connecting frame member 7, the left and right frames 1 , 1 and the connecting frame member 7 are held in a fixed state and can be used as a fixed walking vehicle that can move forward straight.

[Effect of idea]

As described above, according to the present invention, the left and right frames are rotatably provided with the latching fittings in which the latched portions are formed, and the latching portions are provided on the connecting frame member, so that the latching fittings can be rotated. This allows it to be used as an alternating walking vehicle that can move forward alternately or as a fixed walking vehicle that can move forward in a straight line by a one-touch operation of locking and disengaging the locked part and the locking part. With one machine, you can safely perform rehabilitation from initial walking training to full recovery.

Furthermore, in hospitals and the like, the economic and administrative burden of having both alternating walking vehicles and fixed walking vehicles on hand can be significantly reduced.
