Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading stand for a wheelchair, which can be easily attached and detached when the loading stand is attached to a wheelchair and can be tilted to an arbitrary position. Regarding

[0002]

2. Description of the Related Art Conventionally, when a person with a physical disability or a sick person uses a wheelchair, a loading platform such as a table is installed in front of the wheelchair for the purpose of placing various kinds of goods and luggage at the time of getting on and off. It is provided so that the loading platform can be retracted when not in use.

[0003]

However, even though the loading platform of such a wheelchair is configured so that it can be evacuated when getting on or off or not in use, the wheelchair loading platform is fixed in advance to the wheelchair. There is a problem that it is very inconvenient when it is folded, and the weight is added when carrying it.

Therefore, the present invention provides a wheelchair loading platform which allows a user of the wheelchair, such as a physically handicapped person or a sick person, to easily attach and detach the loading platform and tilt it to any position. The purpose is to do.

[0005]

In order to solve the above-mentioned problems, the present invention integrally includes a pair of attachment members for fixing to a frame of a wheelchair, a pair of telescopic arms for detachably attaching a loading platform and a tilting mechanism. The means is to be connected to.

As a result, the user of the wheelchair can easily remove the loading platform when getting in and out of the wheelchair and when not using the wheelchair, so that there is no problem when the wheelchair is folded and the weight of the wheelchair is light, so that it is easy to carry. Become.

As still another invention, in the tilting mechanism, a pin provided on the telescopic arm rotates in the cutout groove of a guide member having an arcuate cutout groove so that the pin can be fixed at any position. That is the means.

Therefore, while the vehicle is still on the wheelchair, the pin is loosened, the loading platform or the telescopic arm is tilted to an arbitrary position, and the pin that rotates in the notch groove of the guide member is tightened and fixed at that position. By doing so, it becomes possible to move the loading platform to a desired position such as in front of the eyes or under the feet.

[0009] As still another invention, since the loading platform is foldable, its means is as follows.
If unnecessary, it can be used anytime, anywhere by removing it, folding it small, storing it in a bag or bag provided in the wheelchair, and carrying it with the wheelchair.

As still another invention, the loading platform and the telescopic arm include a protrusion provided on the back surface of the loading platform,
Since it is detachable by fitting into the notch groove provided at the end of the telescopic arm, it is possible to easily attach and detach the loading platform to and from the wheelchair while the user is on the wheelchair.

FIG. 1 is an overall perspective view showing one embodiment of the present invention. In the figure, 1 is a wheelchair, 2 is a wheel, and 3 is a table-shaped loading platform, which is mounted so as to tilt as indicated by an arrow in the figure. 4a and 4b are a pair of attachment members for fixing the loading platform to the frame of the wheelchair,
It can be easily attached and detached with set screws and tightening screws. 5a and 5b are a pair of tilting mechanisms, 6a and 6b are wheelchair frames, and 7a and 7b are a pair of telescopic arms.

FIG. 2 is an enlarged view of a main part of 5b of the pair of tilting mechanisms 5a and 5b, FIG. 3 is a partially enlarged front view of a mounting portion, and FIG. 4 is an embodiment diagram when mounting a loading platform. . In the tilting mechanism 5b of the present invention, the pin 7c provided on the telescopic arm 7b has a guide member 7 having an arcuate cutout groove 7d.
The pin 7c can be fixed at any position by rotating in the notch groove of e and loosening or tightening the knob of the pin 7c. For example, in FIG. 2, the loading platform 3
To move from the position in front of you to the position under your feet, loosen the knob of the pin 7c, move the loading platform 3 or the telescopic arm 7b and rotate it as shown by the arrow in the figure, and when you reach the position under your feet, The pin 7c is fixed by tightening the knob.

The telescopic arm 7b is slid in the tubular body 7f, and the telescopic arm 7b is fixed at an arbitrary position by loosening or tightening the knob of the fixing pin 7g. 7h is a fixed shaft of the cylindrical body 7f. A notch groove 8 is attached to the tip of the telescopic arm 7b so that the loading platform 3 can be detachably attached.
a, 8b and 9a, 9b are provided in different directions, and the protrusions 3a, 3b provided on the back surface of the loading platform 3 are fitted in either of the grooves.

FIG. 3 is an enlarged front view of the tilting mechanism of FIG.
The mounting state of the mounting member 4b integrally connecting the telescopic arm 7b and the tilting mechanism 5b to the frame 6b of the wheelchair is shown. In this case, even if the mounting site changes depending on the shape of the wheelchair, for example, the position or shape of the frame, the tilting mechanism of the present invention makes the telescopic arm vertical or horizontal, and the position of the loading platform 3 is set to an arbitrary position. It can be adjusted. Furthermore, the mounting members 4a and 4b are
A ring-shaped part that is partly divided is attached so that it does not move with the set screw or tightening screw and is detachable.
Although it is firmly fixed, it can be easily attached and detached, and the attachment site can be easily changed.

FIG. 4 is a diagram showing an embodiment in which the loading platform is attached, but the loading platform 3 is foldable by a hinge 3c. A pair of protrusions 3a provided on the left and right
b is notch grooves 8a, 8b and 9 provided at the tips of the telescopic arms 7a, 7b for detachably attaching the loading platform 3 thereto.
It is fitted and attached to a and 9b. The cutout grooves 8a and 8b are used when setting the loading platform 3 in a position in front of the eyes, and the cutout grooves 9a and 9b are used when it is used in a position below the feet. The embodiment is shown in FIG. 1 and FIG. When the loading platform 3 is not used, it is detached from the telescopic arms 7a and 7b, folded, stored in a bag or bag provided on the back of the wheelchair, or the like so that it can be taken out freely.

As described above, according to the present invention, the loading platform 3 is removed when not in use, folded and stored, and the telescopic arm is also reduced so as not to hinder the operation of the wheelchair.
Then, when the loading platform is needed, for example, when going to the bathroom to brush the teeth, first extend the telescopic arm and fix it at an arbitrary position with the pin 7g, and then take out the loading platform 3. The protrusions 3a and 3b of the loading platform 3 are fitted and set in the notch grooves 9a and 9b. In this way, set the loading platform in front of you and place a toothbrush or cup to brush your teeth. If you want to carry your luggage for shopping or carry other luggage, you should keep the luggage stand 3 or telescopic arm 7a, so that your luggage does not block your view.
7b is moved, and the tilting mechanisms 5a and 5b move the loading platform 3
Is to be moved to the position under the foot and set.

In the above-mentioned embodiment, the loading platform is exemplified by a flat plate like a table.
Not limited to this, it is of course possible to use an appropriate thing such as a net-like thing or a basket-like thing as long as it puts or stores an article.

[0018]

According to the present invention, a user of a wheelchair can easily attach and detach the loading platform while the user is on the wheelchair. Therefore, there is no problem when the wheelchair is folded, and the weight is light, which makes it easy to carry. Moreover, the tilting mechanism allows the loading platform to be easily moved to a desired position such as in front of the eyes or under the feet. Further, by providing the tilting mechanism, even if the mounting position changes depending on the shape of the wheelchair, for example, the position or shape of the frame, the loading platform can be adjusted to any position.
