[0002]

2. Description of the Related Art A wall moving device that moves along a wall of a building includes a "stair stair lift for disabled people" proposed by the present inventor in Japanese Patent No. 253000, and Japanese Patent Application No. 9-1.
No. 8001 proposes a "descent device from an upper floor". The proposed mobile device is roughly described as
A guide rail is installed along the wall surface, and an engaging leg provided on the movable base is slidably engaged with the guide rail to maintain the attitude of the movable base, and can be moved along the guide rail by a driving device. By providing several engaging elements around a rotating member provided at the tip of the rotating shaft on the moving table, and engaging the engaging elements with moving guides arranged side by side on the wall surface, It can move at a substantially constant speed along the guide rail.

[0003] However, the above-mentioned moving device is designed so that each engaging element provided around the rotating member which rotates with respect to the wall surface comes off the guide surface of the moving guide and engages with the guide surface of the next moving guide. In the return stroke during the period, since it is necessary to provide a retreat means for suppressing interference with other moving guides, there is a problem that the structure of the moving device is complicated, more simplified structure, And cost reduction is desired.

[0004]

In order to solve the above-mentioned problems, the present inventor has made various studies and researches in order to realize the retracting means of the engaging element with a simple structure. It has been found that if the engaging element and the moving guide with which it is engaged are installed under certain conditions, smooth movement of the rotating member can be realized without providing any special retreating means. The present invention is based on such knowledge, and its basic technical problem is that a stair climber for a disabled person to use for raising and lowering a staircase of a wheelchair for a disabled person, in a disaster of a building, etc.
Widely applicable as a means to move along the wall of a building such as a descent device that can safely and promptly evacuate and rescue human lives from the upper floor, or an elevating device that raises and lowers luggage in a warehouse etc. An object of the present invention is to make the structure of the wall moving device simpler and more economical.

Another technical problem of the present invention is that the engaging member on the rotating member does not interfere with other moving guides during the return stroke until it comes off the moving guide and engages with the next moving guide. It is to obtain a wall moving device.

[0006]

In order to solve the above-mentioned problems, a wall moving device of the present invention is provided with a guide rail along a wall of a building, and a moving table moving along the guide rail includes: An engaging portion that slidably engages the guide rail while holding the posture is provided, and further, on the movable table,
A rotating member is provided at the tip of a rotating shaft that is connected to a driving device or a speed regulating device and whose driving is controlled. The rotating member is provided so as to face the wall, and rotates around the rotating member. A plurality of engaging elements which are engaged with and guided by the guide surface are equally arranged, and the moving guide disposed on the wall surface moves the engaging element on the rotating member when the rotating member moves along the guide rail. Within the range, the rotating shaft is deviated to one side of the movement trajectory of the rotating shaft and juxtaposed at a constant interval, and when the engaging member of the rotating member rotates while engaging with the guide surface, the rotating member rotates with respect to the rotating shaft of the rotating member. And the length of the moving guide is such that at least one engaging element always engages with the guide surface of the moving guide and each engaging element Off the guide surface of the next In return stroke between until it engages the motion guides guide surface, it is characterized in that it has as a range that does not interfere with the engaging element.

In the wall moving device, by providing a driving device for applying a rotational driving force to the rotating shaft, the moving table can be driven in both forward and reverse directions along the guide rail on the wall. In addition, by providing the rotation shaft with a speed regulating device that regulates the rotation speed, the moving table can be decelerated and lowered by its own weight along the guide rail on the wall surface.

In the wall moving apparatus having the above-described structure, in the return stroke until each engaging element of the rotating member is disengaged from the guide surface of the moving guide and engages with the guide surface of the next moving guide, the other moving process is performed. Since there is no need to provide a retracting means for preventing interference with the moving guide, the moving device can be simplified, and the cost of the moving device itself can be reduced.

Further, it is not necessary to change the shape and other design of the moving guide and the like according to the direction of ascending and descending by the guide rail, that is, the device direction of the guide rail. Just by adjusting the installation angle appropriately, use a stair climber for the disabled to use for raising and lowering the stairs of a wheelchair for the disabled, an elevating device for raising and lowering luggage in warehouses, etc., or evacuation of human lives in the event of a building disaster The present invention can be widely applied as a means for moving along a wall surface of a building such as a descent device capable of safely and quickly performing rescue.

[0010]

1 and 2 show a case in which a wall moving device according to the present invention is applied to a stair climber for a disabled person for transporting a disabled person upstairs or downstairs along a staircase S of a building. Is shown. As shown in FIG. 1, this moving device installs two parallel guide rails 2, 2 along a wall surface W of a staircase S of a building, and moves the moving table along the guide rails 2, 2. The moving table 4 can be moved by a driving device 6 provided on the moving table 4.

The moving table 4 is provided with leg-shaped engaging portions 8 which slidably engage with the respective guide rails 2 and 2 to maintain the posture of the moving table 4. These engagement portions 8
This is for sliding the guide rails 2, 2 while simply holding the guide rails 2, 2 to move the movable table 4 along the guide rails 2, 2. A brake device or the like can be provided between the guide rails 8 and the guide rails 2 and 2 as needed. In this embodiment, two guide rails are installed in parallel, but the required number of guide rails can be installed.

A rotary shaft 10 to which a driving force is applied by a driving device 6 is provided on the moving table 4.
A rotating member 12 having a plurality of arms that rotate to face the wall surface W is provided at the tip of the rotating shaft 10. Around the rotating member 12, a large number of moving guides 14, 14,.
Are successively engaged with and guided by the guide surfaces 14a, 14a,... Of the guide surfaces 14a, 14a,. The rotating member 12 can be in the form of a rotating disk or an arbitrary wheel, and its rotating surface is parallel to the surface on which the moving guides 14, 14,... Are provided. Further, it is desirable that the engaging element 16 is constituted by a rotatable roller.

The moving guides 14, 14,... Move the rotary member 12 along the guide rails 2, 2, that is, when the moving table 4 moves, the engaging members 16 on the rotary member 12 are moved.
Within the movement range (between the straight lines L1 and L2 in FIG. 1),
The rotating members 12 are arranged side by side at a certain interval so as to be deviated to one side of the movement locus of the rotating shaft 10, and the engaging members 16 of the rotating member 12 engage with the guide surfaces 14a, 14a of the moving guides 14, 14,. When the rotating member 12 rotates at a constant speed, the rotating member 12 has an inclination that gives a substantially constant speed in the moving direction of the wall surface W with respect to the rotating shaft 10. The length of the moving guides 14 is such that at least one engaging element 16 is
4 during the return stroke until each engaging element 16 is disengaged from the guide surface 14a of the moving guide 14 and engages with the guide surface 14a of the next moving guide 14. The length is set so as not to interfere with the mating member 16.

That is, as can be seen from FIG. 3 schematically showing the case where the disk-shaped rotary member 12 moves horizontally for simplicity, one engaging element 16 is engaged with the guide surface 14a (see FIG. 3). A) When the rotating member 12 is rotated by the driving device, the engaging member 16 is moved to the guide surface 1 of the moving guide 14.
4a, the rotating member 12 moves in the direction of travel (B to C in the same figure). However, before the engaging member 16 comes off the guide surface 14a, the next engaging member 16 moves in the traveling direction. It engages with the guide surface 14a of the next moving guide 14 (D in the figure), and as a result, the rotating shaft 10 is always kept on the wall surface W of the building.
Can be moved at a substantially constant speed in the moving direction.

More specifically, these moving guides 1
The shape of the inclination and curve of 4 is a circle (rotating member 12) that rotates and moves along a conducting wire (same as the movement locus L of the rotating shaft 10).
It is desirable to have a shape following the cycloid curve which is the movement locus of the moving point (engagement element 16) on the circumference of the circle, but it is desirable to have a shape similar to that for simple manufacturing and low cost. Can be The locus of movement of the engaging element 16 due to the rotation of the rotating member 12 draws a cycloid curve as shown by a curve T in FIG. 3D, and therefore, a certain range on both sides of the moving path T of the engaging element 16 composed of this cycloid curve ( The moving guide 14 does not exist within the radius (the radius of the engaging element 16), but one or more engaging elements 16 may always be in contact with the guide surface 14a of the moving guide 14. In the example of FIG. 3, when the rotation direction of the rotating member 12 is positive, the traveling direction of the rotating shaft 10 is changed from −5 ° to + 5 °.
Although the engaging element 16 is in contact with the guide surface 14a in the range of 90 °, the intended purpose can be achieved.

In the wall moving device having the above-described structure, the engaging member 16 of the rotating member 12 has the guide surface 14a of the moving guide 14.
Since there is no need to provide withdrawal means for preventing interference with other moving guides 14 during the return stroke until it comes off from above and engages with the guide surface 14a of the next moving guide 14, Moving equipment can be simplified,
Consequently, the size and cost of the mobile device itself can be reduced.

That is, in the conventional moving device, it is necessary to employ a means such as inclining the rotating member with respect to the wall surface W as a retracting means for the engaging element, so that the engagement between the engaging element of the rotating member and the moving guide is required. Although it took time and effort to design a moving guide for performing the joining more reliably, the shape of the moving guide was relatively complicated, and the installation work could be relatively difficult. In the apparatus, since it is not necessary to provide the retracting means on the moving table 4 as described above, the rotating member 12 is provided in parallel with the wall surface W, and the guide surface 14a of the moving guide 14 is substantially perpendicular to the wall surface. Therefore, the structure of the moving table 4 and the shape of the moving guide 14 can be simplified, that is, the moving device can be simplified.

Next, FIG. 4 shows another embodiment of the present invention. The wall moving apparatus according to the present invention can safely and promptly evacuate and rescue human lives in the event of a disaster in a building or the like. An example in which the present invention is applied to a descending device which can be used is shown. The lowering device of this embodiment is provided with a moving guide 14 on the wall of the building B.
A pair of descent devices including a pair of descent devices are installed in parallel, and a descent table 24 in which the rotation speed of the rotating shaft is regulated by a speed regulation device in place of the drive device 6 is wound around a pulley 18 on a pulley on the top floor, respectively. Attach it to both ends of the vehicle and connect it with the rope 1 by using the weight of the other when the evacuee or the injured person is put down on one of them.
At step 8, it can be raised to the top floor and returned.

According to the descent device having the above-described configuration, it is possible to safely and quickly descend to the downstairs without power by simply getting on the descent platform 24, and to quickly evacuate not only healthy persons but also disabled persons and injured persons. Effective for rescue. In particular, the lowering device does not require power for lowering unlike an elevator, and therefore can be operated even in the event of a power outage, and can be manufactured simply and inexpensively. In addition,
Other configurations and operations of the descending device in this embodiment are the same as those in the above-described embodiment, and therefore, description thereof will be omitted.

The wall moving device of the present invention is not only a stair climber for disabled persons as described in the above embodiments, and a wall descending device effective for evacuation and rescue at the time of disaster,
It can be widely applied as a means for moving along the wall surface of a building. That is, the moving device having the same structure is connected to the moving guide 14 and the guide rail 2,
