Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a footrest for a wheelchair used by a physically handicapped person, an elderly person and the like.

[0002]

2. Description of the Related Art There are many types of wheelchairs. In general, a pair of left and right large main wheels are attached to the rear end of a chair frame, and small auxiliary front wheels are attached to the front end in a freely directional manner. Because of the need to stabilize the seat, a footrest on which the foot rests is provided at the front end.

[0003] Regarding the form of the footrest, there is a case where the footrest is a single plate (Japanese Patent Application Laid-Open No. 7-194657,
Japanese Patent No. 68944), and a pair of left and right pedals may be used. However, a plate-like shape means that the user rides on the board when getting on and off the vehicle. The use of time puts a strain on the foot. In addition, sometimes a car that supports the footrest is provided so that it does not fall forward when riding on it.However, unless a complicated device that lifts the car is provided, the car can freely move when traveling. Has the disadvantage of being bound.

[0004] On the other hand, a pedal-shaped footrest has the advantage that the user can stand up and get out of the way, and can get on and off without getting on the footrest in such a finished state. In addition, there is also an advantage that a burden is hardly applied to the foot due to the cushioning property.

[0005]

However, the conventional pedal-shaped footrest is inconvenient for the user to perform his / her own work. In the prior art, the foot was lifted with the tip of the foot. First of all, it is necessary to perform a troublesome operation of dipping under the footrest
In addition, in order to turn over to a predetermined position, it is necessary to raise the foot considerably, and in combination with the fact that the foot is weakened, there are many cases where it is impossible to end without the help of a person.

[0006] Even if a nurse or the like closes, it is unsanitary to touch a dirty footrest, and it is necessary to wash hands each time even if it is troublesome. In addition, there is a problem in that the user's own use is painful, for example, when the user forcibly performs an operation to perform the operation, the instep of the foot with weak skin touches the footrest and is damaged.

The present invention has been made in view of the above-described circumstances,
It is an object of the present invention to provide a footrest for a wheelchair that allows a user to safely and easily end up independently.

[0008]

In order to achieve the above object, according to the present invention, a support shaft is provided to protrude forward on both left and right ends of a front end of a chair frame, and a footrest is opened and closed on each of the support shafts. In a wheelchair supported so that it can be stopped and held,
A small pedal for stepping up to open the footrest is protruded from the bearing part of the footrest, and a non-slip hook that bends in the opposite direction to the pushing direction is formed at the tip of the small pedal. The footrest of the wheelchair was constructed.

[0009] Since the footrest of the wheelchair is constructed as described above, in order to open the footrest while the user is sitting, the user steps on the pedal and stands up until the footrest is stopped and held.
Thus, the obstacle to get on and off is released. Further, when the pedal is depressed, the operation can be easily performed because the engaging portion is engaged with the foot. In addition, when using, close by tilting with your feet or hands.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, the form of a wheelchair is not particularly limited as long as it is a pedal type footrest 2 or 2, and for example, a wheelchair having auxiliary rear wheels in addition to auxiliary front wheels. There may be.

As for the means for holding the footrest 2 open, in addition to the stopper type (by the stopper pin 19 and the stopper piece 31) as shown in the embodiment, a means by friction or a bias by a spring is used. Various means are conceivable, such as by engagement with a retractable pin.

Further, as shown in the embodiment, it is not always necessary to invert the directions or angles at which the footrests 2 and 2 are raised to the state where they are inclined to the opposite side. That is, for example, when taking the above-mentioned stopping means by friction or pinning, it is possible to stop at an inward inclination.

[0013]

As described above, according to the footrest of the wheelchair of the present invention, the footrest can be opened and closed by an extremely simple operation of a disabled person or an elderly person depressing a small pedal. There is an excellent effect that the user can get on and off the vehicle independently without the help of a nurse or the like, and there is no danger of damaging the foot and the device can be used conveniently and safely.

[0014]

Next, an embodiment of the present invention will be specifically described with reference to the drawings.

FIGS. 1 to 3 show an embodiment, in which a wheelchair is provided with a chair frame 1 as shown in FIG.
In a traveling mode in which the large main wheels 3, 3 and the auxiliary front wheels 5, 5 are mounted, a pair of left and right pedal-shaped footrests 2, 2 are mounted on the front end so as to face each other until the standing state is reached. It is pivotally supported so that it can be inverted. In addition, 8 is a drive ring, 1
0.10 is a push handle.

The footrests 2 and 2 are made of plastic. A small pedal 7 is mounted on the opposite side of the reversing center bearing 6, and when the small pedal 7 is depressed, the footrest 2 rises. It is designed to open. Then, in the open state, the center of gravity is positioned slightly outside (ie, inclined outwardly), and the open state is maintained (see the two-dot chain line in FIG. 3). In other words, the footrests 2, 2
Is restricted to a substantially right angle.

For mounting the footrests 2, 2, the bearing 6
Is formed in a tubular shape through which the support shaft 11 passes, and the support shafts 11, 11 are protruded from left and right vertical members 9, 9 provided at the front end of the chair frame 1, and a base piece 13 formed of plastic is provided thereon. After the fitting, the bearing portion 6 is fitted, and a cap 15 is fitted to the tip so as not to come off and screwed.

With respect to the regulation of the opening / closing range α, circular notches 17 and 17 are provided on the inner peripheral surfaces at both ends of the bearing 6 in a semicircle, and a stopper pin 19 with which the circular notch 17 engages is supported on the support shaft 11. Is protruding. Then, when the foot pedal 2 is turned outward by stepping on the small pedal 7, the circular notch 17
The other end abuts against the stopper pin 19 and is held in its inclined state. In order to return to the original state, it is only necessary to push a little inside using a footrest or hand.

The small pedal 7 protrudes slightly upward (FIG. 3), and a protrusion 21 is formed at the protruding tip to bend further upward. Due to the presence of the bent portion 21, the foot can be easily hooked, and the footrest 2 can be easily depressed many times downward so as to be inverted to a predetermined position.

FIGS. 4 and 5 show another embodiment. In this case, the bearing 6 between the footrest 2 and the small pedal 7 is formed to be narrower. Is inserted into the support shaft 11 and the holding block 2 made of plastic is
5, the opening / closing range α is regulated.

The holding block 25 has a base piece 27 and a tip piece 29 connected by a stopper piece 31 and has a so-called U-shape with the bearing 6 interposed therebetween. A receiving surface 33 that hits in a state of being pressed and a receiving surface 35 that hits the small pedal 7 when standing up are formed. The holding block 25 is fixed to the support shaft 11 so as to be fitted to the vertical member 9.
