Description

  The present invention relates to a wheelchair fixing device that fixes a wheelchair in an installation space provided on a bus.

  Traditionally, route buses have been obliged to provide an installation space for installing a wheelchair.Usually, a chair that is placed in front of the central entrance and exit is foldable, and the installation space for the wheelchair is reduced. Secured. In order to fix the wheelchair in the installation space, a rail member is installed at a position sandwiching the wheelchair back and forth, and a hook provided on the other end of the belt with one end fixed to this rail member is hooked on the wheelchair frame, Tension is applied to the belt by a retractor or buckle provided in the middle of the belt. Accordingly, the wheelchair can be fixed even when the wheelchair user is seated on the wheelchair by pulling the wheelchair in the front-rear direction (see, for example, Patent Document 1).

JP 2001-212179 A

  However, in a wheelchair, usually, a large wheel for driving the wheelchair is disposed on the outermost side in the width direction, so that the hook of the wheelchair fixing device is hung on a frame disposed between the wheels. Further, a handle for pushing is usually provided above the wheel.

  And the installation space is usually provided close to the front of the step that forms a step between the rear seat that is placed one step higher so as to get over the tire house of the rear wheel of the bus. In general, a partition wall that partitions both spaces is provided between the space and the seat behind the space. For this reason, when a wheelchair is arranged in the installation space, the space behind the wheelchair is closed by the partition wall.

  Therefore, in a conventional wheelchair fixing device that applies a tension to the belt by operating a retractor or buckle disposed in the middle of the belt, the operator on the side of the bus aisles operates the wheel and the handle. There is an inconvenience that work must be performed between the wheels through a narrow gap between the wheel and the workability.

  In particular, the wheelchair is arranged with its front-rear direction aligned with the front-rear direction of the bus because of the installation space, that is, the wheelchair user seated on the wheelchair is fixed so as to face the front of the bus. For this reason, when the wheelchair frame is fixed to be pulled backward using two belts, it is difficult to reach the retractor or the buckle provided on the belt arranged on the window side, and the operation is difficult. There is inconvenience that it is.

In the case of an electric wheelchair, since a drive device such as a motor for driving the wheels is disposed between the wheels, the retractor or buckle provided on the belt disposed on the window side is viewed from the passage side. Since it is arranged on the back side, there is a problem that the operation is further difficult.
In addition, in the conventional wheelchair fixing device in which the retractor or buckle is arranged in the middle of the belt, the position of the retractor or buckle that is a mass having a relatively large weight and volume is not fixed in a state where the belt is not tensioned. When not in use, it will be in the way unless it is removed and stored elsewhere.

  The present invention has been made in view of the circumstances described above, and it is an object of the present invention to provide a wheelchair fixing device that does not get in the way when not in use and can easily perform a task of fixing the wheelchair at the time of use. It is said.

In order to achieve the above object, the present invention provides the following means.
The present invention relates to a wheelchair fixing device for fixing a wheelchair by aligning the front-rear direction of the wheelchair with the front-rear direction of the bus in an installation space disposed between the window side wall and the passage of the bus, and is pulled forward. Traction means for traction of the wheelchair backward, the traction means being hooked on a frame of the wheelchair, a belt having the hook attached to an end thereof, and a manual retractor for applying tension to the belt; A through-anchor having a through-hole through which the belt passes, the through-anchor being fixed to a step wall surface behind the installation space, and the manual retractor being positioned on the passage side of the step wall surface with respect to the through anchor A wheelchair fixing device is provided.

According to the present invention, the wheelchair is arranged in the installation space provided between the bus passage and the window side wall so that the front-rear direction coincides with the front-rear direction of the bus, and the towing means is operated in a state where the wheel is pulled forward. By pulling backward, the wheelchair can be pulled and fixed in both the front and rear directions.
To pull backward by the pulling means, a tension is applied to the belt by hooking a hook attached to the end of the belt on the frame of the wheelchair and operating the manual retractor. The belt is bent to the passage side by passing through the through-hole of the through anchor, and wound by a manual retractor fixed to the position on the passage side from the through anchor.

  Therefore, the worker who performs the fixing work for fixing the wheelchair can operate the manual retractor disposed sufficiently close to the passage side as compared with the conventional case of pulling the belt straight backwards, Conventionally, it is possible to greatly improve the workability of the fixing work by the manual retractor that has been performed in a state in which it is difficult to reach from the gap between the wheel and the handle. In particular, the manual retractor can be disposed on the side of the passage from the wheel of the wheelchair, and in that case, the fixing work can be easily performed outside the wheelchair.

  In addition, manual retractors and through anchors fixed to the step wall at the rear of the installation space may roll or displace due to the shaking of the bus without being removed when not in use. Don't be. Therefore, it is not necessary to take out and attach the wheelchair fixing device that has been removed and stored only during use, and it is possible to use the wheelchair fixing device simply by feeding the belt wound up to the position of the through anchor.

In the above invention, the hooking tool includes two hooks that are respectively hooked on the left and right frames of the wheelchair, two branch belt portions each having the hooks attached to the end portions, and the branch belt portions from the belt. A branching tool for branching may be provided.
In this way, when the manual retractor is operated to apply tension to the belt, the tension is branched into two branch belt portions by the branching tool, and hooks attached to the end portions of the branch belt portions are attached. The left and right frames of the wheelchair are each pulled backward. Thereby, it is possible to stably fix the wheelchair by towing the wheelchair at the front and rear three or more places only by towing the wheelchair forward at one or more places.

Further, in the above invention, the traction means includes two each of the hooking tool, the belt, the manual retractor, and the through anchor, and each hooking tool is provided on the left and right frames of the wheelchair. Each may be hung.
In this way, the left and right frames of the wheelchair can be pulled separately and independently.
Even in the case where the space between the wheels is filled with a driving device such as a motor, the wheelchair can be passed around avoiding contact with the driving device, and the wheelchair can be more securely fixed.

Moreover, in the said invention, while the said manual retractor is provided with the handle rotated in order to wind up the said belt, it may be fixed to the said step wall surface with this handle facing up.
In this way, the take-up shaft that is connected to the handle and winds up the belt can be arranged in the vertical direction, and the through-anchor that is fixed at a position substantially horizontally away from the manual retractor is provided. The belt route extending to the wheelchair frame can be arranged without difficulty. Further, the handle can be accessed from above, and the fixing work by rotating the handle can be further facilitated.

In the above-mentioned invention, there is provided a take-out hole through which the belt that has passed through the through-hole of the through-anchor is penetrated, the manual retractor, the through-anchor and the belt are accommodated, and a cover that can be opened and closed is provided. Also good.
By doing so, the belt part that opens the cover and operates the manual retractor during the fixing work, closes the cover after the fixing work is completed, accommodates the manual retractor and the through anchor in the cover, and penetrates the takeout hole Only the outside of the cover can be exposed. When not in use, the belt including the belt wound up to the position of the through anchor can be accommodated in the cover.

  According to the present invention, there is an effect that an operation of fixing a wheelchair can be easily performed at the time of use without being disturbed when not in use.
