Abstract

PURPOSE:To provide an elevator apparatus capable of maintaining a constant mounting position and smoothely moving even if a horizontal spot is on the way of elevation. CONSTITUTION:While a guide rail 3 for elevation is disposed obliquely along a stair case, a elevator driving body 5 for guiding drivably the elevator along the rail 3 is provided. A mounted elevator apparatus supports a mounting member 6 for mounting a transferred article on the elevator driving body 5. While the elevator driving body 5 is guided end engaged with the rail 3 relatively pivotably and movably about the lateral axis, a guide roller 15 supported by the elevator driving body 5 is guided and engaged with the upper or lower section of the rail 3 and an auxiliary rail 16 for holding the position of the elevator driving body 5 is disposed approximately along the rail 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading and unloading device used, for example, when a physically handicapped person climbs stairs or lifts or lowers luggage along the stairs in a factory.
Specifically, a rail for guiding up and down is arranged diagonally along the stairs, and an elevating and lowering driving body that guides and moves along the rail is provided, and a mounting member for mounting an object to be conveyed is mounted on the elevating and lowering driving body. The present invention relates to a supporting lifting device.

[0002]

2. Description of the Related Art In the above-mentioned mounting and elevating device, conventionally,
The lifting drive body and the mounting member are integrally fixed so that a load, a person, or the like mounted on the mounting member can maintain the same horizontal posture during the lifting operation.

[0003]

However, in the above-mentioned conventional structure, it is convenient when the staircase has only a linear portion, but, for example, when there is a landing in the middle of the staircase, If the rail is extended linearly, the rail is separated from the upper stairs, and there is a drawback that it is dangerous when the transported object is lowered from the mounting member or a passenger gets off. The present invention aims to eliminate the above-mentioned problems.

[0004]

According to a characteristic configuration of the present invention, in the mounting and elevating apparatus described at the beginning, the elevating and lowering drive member is rotatable relative to the rail about a horizontal axis and can be driven and moved. While being guided and engaged, a guide roller supported by the elevation drive body is engaged and guided above or below the rail, and an auxiliary rail for maintaining the posture of the elevation drive body is arranged substantially along the rail. It is in the point that is set.

[0005]

In the middle of the rail, even if the rail is bent from an oblique posture to a horizontal posture along a landing of a stairway, the lifting drive unit moves up and down while moving along the rail. The guide roller supported by the driving body is engaged with and guided by the auxiliary rail, and holds the posture while relatively rotating with respect to the rail around the horizontal axis. Therefore,
Even if the rail is bent along the stairs, regardless of the bending of the rail, the lifting drive and the mounting member move integrally while always maintaining a constant horizontal posture. Even at the end, it does not leave the stairs.

[0006]

As described above, according to the present invention, even when the object to be conveyed is placed and lifted in the diagonal direction along the stairs, even if there is a horizontal place in the middle of the lifting, Maintaining the condition that the transported object is always placed in a fixed posture,
In addition, the loading member can be set at a position close to the stairs on each of the movement start end side and the movement end side, and the loading and unloading of the loaded luggage and the loading / unloading of physically handicapped persons can be performed safely. . Moreover, since the posture is maintained by the guide of engagement between the guide roller and the rail, it is possible to smoothly move without rattling.

[0007]

Embodiments will be described below with reference to the drawings. Figure 4
In FIG. 1, there is shown a loading / unloading device for loading and unloading a physically handicapped person, luggage, etc. along stairs. In this placement and elevating device, a main rail 3 for raising and lowering guides is fixedly attached to a lateral wall 2 of a stairway 1 in a diagonal direction along the stairway 1, and a moving device 4 for driving and elevating along the main rail 3 is provided. Configured. The moving device 4 is configured by integrally fixing an elevating / lowering drive body 5 in which an electric motor M1 for moving drive is installed, and a mounting member 6 arranged on the upper part thereof. An object to be conveyed such as luggage or a person is placed on the placing surface 6a and is configured to be movable up and down along the rail 3.

More specifically, the main rail 3 is shown in FIG.
As shown in FIG. 3, the moving member is formed to have a rectangular cross section, and the moving member moves up and down along the stairs while being bent along the landing S1 and the rotating stairway portion S2 in the middle of the stairs 1. A rack gear 8 is formed in the central portion on the upper surface side of the main rail 3 over substantially the entire length in the longitudinal direction, and a pinion gear 9 provided on an elevating / lowering body meshes with the rack gear 8 to engage the pinion gear 9. The elevation drive body 5 is moved up and down by being rotationally driven by the electric motor M1. That is, a frame 10 for covering the rails 3 is provided on the elevating / lowering drive body 5, and a pair of left and right main bodies is slidable in the longitudinal direction on the roller guide portions 11 formed on the left and right side surfaces of the main rail 3 and vertically regulated in position. The guide roller 14 is supported by the frame 10. Therefore, the elevating / lowering drive body 5 is configured to be rotatable relative to the main rail 3 around the horizontal axis of the main guide roller 14. Further, the output of the electric motor M1 supported by the frame 10 is configured to rotatably drive the drive support shaft 13 of the pinion gear 9 supported by the worm gear type reduction mechanism 12 in a state of being engaged with the rack gear 8 at a low speed. There is.

The frame 10 is extended obliquely downward, the auxiliary guide roller 15 is supported by the extending portion 10a, and the auxiliary guide roller 15 is moved up and down.
An auxiliary guide rail 16 is slidably provided in the moving direction of the above and is guided in a state where the position is regulated in the vertical direction.
As a result, the postures of the lifting drive body 5 and the mounting member 6 are restricted by the engagement of the main guide roller 14 and the main rail 3 and the engagement of the auxiliary guide roller 15 and the auxiliary rail 16. And the pinion gear 9
By the interlocking drive between the rack gear 8 and the rack gear 8, the drive gear moves up and down along the main rail 3. In the landing S1 of the stairs 1, the main rail 3 is formed so as to be bent from an inclined state to a horizontal state and extend in a posture along the stairs 1 as shown in FIG. Further, as shown in FIG. 3, the round staircase portion S2 is formed so as to be bent in the lateral direction.

The auxiliary rail 16 is set at a distance from the main rail 3 so that the guide rollers 14 and 15 maintain their relative horizontal postures at a constant level. The elevating / lowering drive body 5 and the mounting member 6 are always configured to maintain a constant horizontal posture regardless of the bending at the landing S1 and the bending at the staircase portion S2. In this way, it is possible to raise and lower the transported object in a stable mounted state while smoothly moving up and down.

It should be noted that reference numerals are added to the claims for facilitating the comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
