Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a wheelchair slope installed at an entrance of a building or a step inside a building. For wheelchairs designed to eliminate the slope inclination by raising the vertical movement mechanism as necessary and raising the low side of the slope road board to the high level as necessary It relates to a slope device.

[0002]

2. Description of the Related Art As the proportion of the population occupied by the elderly increases,
Barrier-free mental and living environments are being promoted. In order to improve the usability of wheelchairs, various steps that exist in the living environment have been promoted as an ingenuity in the barrier-free living environment. However, steps in the living environment include steps that are difficult to eliminate due to their nature, such as steps that occur between the site and the floor of a building built on the site.

[0003] Such a step that is difficult to eliminate, for example, a step at a building entrance, is not only a general method of providing a slope as a fixed material on the site, but also a lifter at the entrance, in addition to the stairs at the entrance. A method in which the device is buried and the wheelchair is mounted on a lifter device and pushed up to the floor level of the building (Japanese Patent Application Laid-Open No. Hei 7-101687, Japanese Utility Model Application Laid-Open No. 6-63028), or supported at the entrance via a lifter device. A method of temporarily forming a slope reaching the building floor level at the entrance by embedding the slope plate in a horizontal position and pushing up one end of the slope plate as needed for wheelchair passage ( Japanese Unexamined Utility Model Publication No. 6-63028) has been proposed. Furthermore, for the purpose of determining the slope, a slope of a model house for experiencing the physically handicapped, the elderly, and the caregiver (Japanese Patent Laid-Open No. 2000-293)
No. 81) has also been proposed.

[0004]

The use of a wheelchair can be divided into a case where an assistant attends and a case where an assistant does not attend. Generally, a slope as a fixing material of a site is widely used in facilities for public use. And the slopes set up here are not for specific individuals but for wheelchair users with poor strength,
The slopes are so slow that they can be used on their own. Even if a suitable slope can be designed by forming an experimental slope on a trial basis, inconvenience is often felt over time. In addition, the overall length of the slope is long and it is difficult to adopt it for ordinary households because it requires a large site.

On the other hand, when a wheelchair is pushed directly to the building floor level by a lifter device, the lifter device must be used even when an assistant is present. Is uneconomical and cumbersome.

In the method of temporarily forming a slope at the entrance by pushing up one end of the slope plate, the slope is steep because the length of the slope is restricted from the size of the usual entrance. There is a drawback that if the helper is not present, it cannot be used effectively.

[0007] Therefore, the present invention is to use the slope as it is when the wheelchair user is a wheelchair user with an assistant or a wheelchair user without an assistant but with physical strength. If the wheelchair user is a powerless user without a helper, the slope of the slope can be eliminated through the lifter device, which is convenient for the wheelchair user. It is an object of the present invention to provide a wheelchair slope device capable of significantly reducing a slope without impairing performance.

[0008]

The present invention employs the following structure as means for achieving the object.

The wheelchair slope device includes a high-level horizontal board installed at a high level, a low-level horizontal board installed at a low level via a vertical movement mechanism, a high-level horizontal board, and a low-level horizontal board. In a wheelchair slope device including a slope road plate communicating between road plates, a high-altitude horizontal road plate and a high-side end of the slope road plate are swingably connected to each other via a hinge pin. The horizontal road board and one end on the low side of the slope road board are connected by pin holes and hinge pins, which have long holes, and the vertical movement mechanism maintains the low The first feature is that the ascending and descending drive is enabled within a range between a place level and a low place level.

A fence and a telescopic gate are installed on the low-level horizontal road board, and button switches for driving the vertical movement mechanism are provided on the high-level horizontal road board side and the low-level horizontal road board side. ing. In this configuration, since the slope road board connects the high-level horizontal board and the low-level horizontal board, the wheelchair user moves to a high level using the slope board as it is by himself or by an assistant. can do. In this case, the fence and the expansion gate on the side of the low-level horizontal road board are useful for stopping the wheelchair even if the vehicle slides in the opposite direction to the low level in the middle of the slope, and is important for safety. On the other hand, wheelchair users who cannot travel on their own on the slope of the sloped road board, if they move on the low-level horizontal board and operate the vertical movement mechanism, the low-level horizontal board will rise to the high level level, The bent high altitude horizontal road board, the slope horizontal road board, and the low horizontal road board swing so as to form a straight line, and the slope of the slope road board is eliminated. Therefore, the wheelchair user can move to a high altitude level with the same effort as when traveling on a flat road. Thereafter, if the low-level horizontal road board is lowered via the vertical movement mechanism, the slope road board can return to the original inclined posture.

The vertical movement mechanism for supporting the low-level horizontal road board includes a pair of cross legs, and a hydraulic cylinder for driving the pair of cross legs to open and close. Each cross leg has two arms. It is characterized in that the intermediate portions are overlapped and integrated so as to be openable and closable using a shaft, and the hydraulic cylinder is driven to open and close in synchronization with a pair of cross legs.

The low horizontal road board is supported in a horizontal posture by a pair of cross legs, and the two arms constituting each cross leg decrease the height by the opening operation and increase the height by the closing operation. Shape changes. Therefore, when the pair of cross legs are driven synchronously in the opening direction by the hydraulic cylinder, the low-level horizontal road board rises while maintaining the horizontal posture, and the pair of cross legs are driven synchronously in the closing direction. This allows the low-level horizontal road board to descend while maintaining the horizontal attitude.

In the wheelchair slope device, a fence in which vertical pipes are arranged along a longitudinal side edge of the slope road board is installed at a low level, and a longitudinal side edge of the slope road board is installed. A fence with vertical pipes arranged in a part is installed, and at this time, the upper end of the low-level fence side vertical pipe is fitted freely into and out of the lower end of the fence side vertical pipe of the slope road board. can do.

In this configuration, the fence installed at the side edge of the sloped roadbed prevents the wheelchair user coming and going from falling using the sloped roadbed, and the low point is provided along the side edge of the sloped roadbed. The fence provided at the level can prevent a child or the like from entering the lower space of the slope road board caused when the slope road board is raised. Then, when the slope pipe is lowered, the upper end of the vertical pipe forming the low-level fence is freely fitted into the lower end of the vertical pipe forming the fence of the slope road board. Since the vertical pipe of the fence of the place level is stored in the vertical pipe of the fence of the slope road board, the upper and lower fences do not overlap, and a neat appearance can be maintained regardless of the operation position of the slope road board.
