Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a wheelchair storage device that allows a wheelchair used by a disabled person to be stored in a storage case installed on the roof of a car, and particularly relates to its handling. This invention relates to a wheelchair storage device for a vehicle that allows easy, safe and reliable operation of the wheelchair.

[Conventional technology]

Traditionally, when a person with a disability who uses a wheelchair drives or gets into a car, he or she sits in the driver's seat or seat from the wheelchair, folds the wheelchair, and places it in the passenger seat or rear seat. I had to load it into the car.

When getting off the vehicle, the loaded wheelchair is unloaded onto the ground and assembled, and then the user transfers onto the wheelchair.

Even if a person with a disability drives a car or simply rides in a car, the wheelchair itself is bulky and heavy, and there is only a certain amount of space inside the car, so it is difficult to carry the wheelchair. Wholesaling requires a lot of effort and care,
It has become a difficult task.

For this reason, for example, Japanese Patent Application No. 173484 (Sho 56-173484)
58-76342) has been proposed.

In this invention, a rail mechanism consisting of three sets of folding rails that can slide and rotate in the width direction of the vehicle body is arranged on a base provided on the roof of the vehicle, and a wire rope is wound around a winch. Through a drive source such as an electric motor, this rail mechanism is moved along the width direction of the vehicle body toward the outside of the vehicle body.
The wheelchair is slid in a hanging state along the car door opening and is locked to a locking mechanism attached to the most advanced third rail.

Then, each rail mechanism is sequentially slid and rotated in the opposite direction, the wheelchair is folded, the wheelchair is mounted on the base on the roof, and the top lid is closed.

However, the wheelchair loading device having the above configuration has the following drawbacks.

In other words, since wire rope is used,
When winding into the drum, the wire rope winds up in a disorderly manner, making it impossible to slide or fold the rail mechanism at a constant speed, making it difficult to load and unload the wheelchair smoothly.

In addition, with this loading device, the locking mechanism for locking the wheelchair is attached to the top of the third rail, so the wheelchair cannot be locked unless it is placed in the correct position, and the user must try again. The disadvantage was that the wheelchair could not be locked unless it was placed in the correct position or the vehicle was moved in the opposite direction.

In addition, if a failure occurs in the drive source of this invention,
A fatal drawback may arise in that the wheelchair cannot be loaded or unloaded, and the wheelchair cannot be used by a disabled person.

Furthermore, depending on the size of the wheelchair, the wheelchair cannot be accurately and stably locked in the locking mechanism, resulting in the disadvantage that the wheelchair cannot be stored.

[Problem that the invention attempts to solve]

This invention was created in view of the above points,
By using a belt structure instead of a wire rope, the above-mentioned random winding is prevented, and the rail mechanism is configured to be able to slide and rotate smoothly at a constant speed, so that loading and unloading of wheelchairs can be carried out reliably.

Moreover, it has excellent operability, allowing the wheelchair to be locked in the locking mechanism even if the wheelchair is not in the correct position during loading, and can be used safely and reliably by manual operation even if the drive source fails. The purpose of the present invention is to provide a wheelchair storage device for a vehicle that has the following features.

[Means for solving problems]

In order to achieve this purpose, the present invention is based on the first to third
A rail mechanism consisting of a rail is installed in a storage case installed on the roof of the vehicle body, and a drive belt mechanism that slides and rotates this rail mechanism from the width direction of the vehicle body along the door opening, and a drive belt mechanism that is manually operated. The main points of this invention are a locking mechanism in which the third rail at the most advanced end of the rail mechanism is configured with adjustable gripping pieces that can grip the wheels of the wheelchair in accordance with the size of the wheelchair.

After locking, the wheelchair A can be stored in the storage case 2 by rotating the drive source 11 in the opposite direction, sliding the rail mechanism 20 in the opposite direction, and folding it.

[Effect of idea]

Since the present invention has the above-mentioned configuration, by using the belt 14 such as a seat belt as the drive belt, accurate pulling out or winding is possible, and since it prevents random winding like a wire rope, the speed is always constant. The rail mechanism can slide and rotate smoothly.

In addition, by providing the locking mechanism 24 directly at the tip of the belt 14, the locking mechanism 24 has play, and even if the wheelchair A is out of position, it can be locked, making the loading operation extremely simple. Become. In addition, it is lightweight, prevents metallic noise, and improves operability.

Moreover, by configuring a safety mechanism consisting of a manual mechanism 120, in the event that the drive source 11 fails, the clutches 121, 1 can be activated by operating the lever 129.
22, the drums 12, 12 are rotated either forward or reverse, and the rail mechanism 20 is slid or rotated, whereby the wheelchair A can be loaded and unloaded safely and accurately.

Furthermore, in the present invention, by providing the locking mechanism 24, it is possible to easily adjust the position of the clamping piece 94 depending on the size of the wheelchair A to be used. It can be done with a nut and has great effects, such as being simple and hassle-free.
