Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an ascending / descending device that can be used by both a wheelchair user and a normal person who can move up and down stairs by a vertical movement and a horizontal movement by a wheelchair user, and a normal person can go up and down the stairs by following a tread.

[0002]

[Prior art]

 For wheelchair users, various proposals have been made to raise and lower the wheelchair using power. However, it is often uneconomical to follow the same course as a wheelchair when a healthy person goes upstairs and rises upstairs, or vice versa. For this reason, it is strongly recommended that wheelchair users have means to move the wheelchair up and down by power, and that healthy people can use the same facility or device to quickly move up and down by themselves without consuming power. It was requested.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, and an object thereof is to provide a combined lifting device that can be used by both wheelchair users and healthy people.

[0004]

[Means for Solving the Problems]

 The first gist of the present invention is as follows. One end is rotatably supported below the uppermost tread, and B. The other end is supported by a guide roller part which is axially supported by the tip part of the table part, which will be described later. It is installed diagonally between the top and bottom of the stairs. E. Bridges on both the left and right sides, which slide on the guide roller portion as the table portion rises, so that each of the other end portions successively protrudes to the lower side of the table portion; Both ends are pivotally suspended between the bridge parts on both sides, and as the table rises, they rotate downward and overlap the ends of the treads pivotally supported by the adjacent parts so that all treads are almost horizontal. A plurality of tread portions that are continuously laid, and F. A stopper portion which extends from the other end of each tread portion and is held by a separately provided supporting portion when the bridge portion descends to hold each tread portion substantially horizontally. The bridge part is composed of a table part, the tip part of which is pivotally supported on the other end part of the bridge part, and a wheelchair is placed on the table part to move up and down a predetermined height by power. It is a combined lifting device for wheelchair users and healthy people.

The other second gist is as follows. One end is pivotally supported below the uppermost tread portion, b. The other end is connected to a crank portion that rises and falls as the table portion described below moves up and down, c. A bridge portion that is installed obliquely between the top and bottom of the stairs, and d. Both ends are pivotally suspended between the bridges on both sides, and as the table rises, they rotate downward and overlap the ends of the treads pivotally supported by the adjacent parts so that all treads are connected almost horizontally. A plurality of tread portions that are continuously laid; e. A stopper portion which extends from the other end of each tread portion and is held by a separately provided support portion when the bridge portion descends to hold each tread portion substantially horizontally. F. It consists of the other end of the clamp part, and the table part whose tip end is rotatably supported and on which a wheelchair is placed and which moves up and down to a predetermined height by power g. This is a lifting device for wheelchair users and healthy people.

【Example】

 FIG. 1 is an explanatory view showing an embodiment of the combined lifting device according to the present invention, and FIG. 2 shows a method in which the bridge part of the device slides on the guide roller part and projects below the table part. FIG. 3 is an explanatory view showing another embodiment having a crank portion which rises and falls as the table portion moves up and down, and FIG. 3 is an explanatory diagram showing a front flap portion attached to the table portion.

The device of the present invention shown in FIG. 1 is mainly composed of a bridge portion 1, a table portion 2, a plurality of tread plate portions 3, and a stopper portion 4 for holding each tread plate portion substantially horizontally. The bridge portion 1 has one end portion 5 pivotally supported on the upper floor portion below the uppermost step plate portion 5a, and when the table portion 2 is downstairs, the bridge portion 1 is obliquely provided between the upper and lower stairs. As shown in FIG. 3, the bridge portion 1 is provided on both left and right sides with the tread portion 3 interposed therebetween. The bridge part 1 moves up and down to the position 1a or the position 1 shown in the drawing as the table part 2 moves up and down.

As the bridge portion rises from the position 1 to the position 1a, as shown in FIG. 3, the guide roller portion 8 pivotally supported on the tip portion of the table portion 2 slides to the other end. The portion 1b sequentially projects to the lower side of the table portion. FIG. 3 shows a state in which the bridge portion finally rises to a horizontal position and the other end portion 1b projects to the longest.

As shown in FIG. 1, FIG. 2 and FIG. 3, the tread plate portion 3 is suspended between the bridge portions on both the left and right sides with its both ends pivotally supported by each bridge portion 9. As it rises, it rotates downward and overlaps the end of each tread that is axially supported by the adjacent part, and all treads 3 are almost horizontal as shown in the bridge 1a at the time of ascent in FIG. Are continuously laid.

A stopper portion 4 extends from the other end of each tread plate portion 3. The stopper portion 4 is supported by a separately provided bearing portion 10 at its tip portion 4a when the bridge portion 1 is lowered. The support portion 10 may be at an existing stage or the like, but may be other than this as long as it can lock the end 4 a of the stopper portion 4. Each tread part 3 supported by each stopper part 4 is used as an elevating staircase for a healthy person.

The table portion 2 raises and lowers a wheelchair and its user by hydraulic pressure, water pressure, an electric device 15, or the like. As shown in FIG. 1 and FIG. 3, the table portion 2 can move upstairs by passing a tread plate portion that forms a horizontal state when a wheelchair is placed and rising, and when descending, the table portion 2 is on the ground. Can be moved.

FIG. 2 shows another embodiment according to the present invention. This is one in which the respective end portions 13 and 14 of the bridge portion 1 and the table portion 2 are connected by two clamp portions 11 which are pivotally supported 12, and the clamp portion 11 stands up when the table portion is raised or lowered. Or, the user can lie down and adjust the distance between the bridge portion 1 and the table portion 2 in a connected state.

The table portion 2 is axially supported by the end portion of the table portion 2 on the bridge portion 1 side, and when the table portion 2 descends, it falls down to the bridge portion side to form a tread plate portion, and at the time of standing up, the safety of the wheelchair can be secured. A front flap portion 15 is provided. Further, although not shown, a rear flap portion can be provided to facilitate mounting or separation of the wheelchair with respect to the table portion 2.

[0014]

[Effect of device]

 The present invention is based on the above-mentioned configuration. Since the bridge part moves up and down as the table part moves up and down, and the tread plate part forms a horizontal state or a stepped state at the same time, a wheelchair user in a horizontal state. It is also very useful because it can be used for lifting and lowering normal persons in the step condition when the bridge is tilted, and can be used as a combined lifting device between the upper and lower floors at any time and anywhere.
