Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for storing objects on a ceiling, and more particularly to a device for moving a storage box up and down.

[0002]

2. Description of the Related Art Heretofore, there has been no known device for accommodating an article on a ceiling, in which an accommodating box is vertically moved. By the way, when the storage box is moved up and down, when it is moved up and down while sufficiently supporting the weight of the storage box, it is generally known that it is moved up and down while being supported by guide means such as a guide rail like an elevator. In this case, if only the back side of the storage box is supported and guided, it cannot support the weight because it is in a cantilever state, so it is necessary to support and guide the side and front sides by the guide rails. In this case, the guide rail remains under the ceiling even when the storage box is stored behind the ceiling.For example, the guide rail on the rear side can be along the wall surface, but the guide rails on the side surface and the front side are It gets in the way and is not easy to use.

On the other hand, as a means for moving the storage box up and down without leaving a guide rail under the ceiling, a method of suspending the storage box with a wire is known. An apparatus described in Japanese Utility Model Laid-Open No. 57-45549 is known as a storage apparatus using this method. This device is designed to store a storage box under the floor, not at the ceiling, and a wire rope is hung from a shaft installed in the main body via a pulley supported on the main body and stored in this. A box mounting base is attached, two storage boxes are mounted on the storage box mounting base, and the storage box mounting base is moved up and down by winding and winding the wire rope.

[0004]

As described above, when the storage box is hung by the wires, when the storage box is stored in the ceiling, nothing is left under the opening, which is convenient. Since the wire has no horizontal movement regulation force, the stability of the storage box is poor. For example, when the storage device described in the above publication is applied to a ceiling storage device, since the storage box is only placed on the storage box mounting base hung with wires, there is a risk that the storage box mounting base may wobble in the horizontal direction. There is a bad balance, and when the two storage boxes are in a single load state,
The storage box and the storage box mounting table may also tilt.

The present invention has been made by paying attention to the above-mentioned problems, and when the storage box is stored in the ceiling, guide rails and the like do not get in the way and the stability of the storage box is improved. An object is to provide an excellent ceiling storage device.

[0006]

In order to achieve the above-mentioned object, in the ceiling storage device of the present invention, an opening is formed in the ceiling in the vicinity of the wall surface of the building, which communicates between the interior of the ceiling and the interior of the room. A guide rail extends in the vertical direction along the wall surface to a predetermined height in the room through the opening, and a slider slidable on the guide rail is formed to have a size that allows the opening to come in and out. Is mounted on the back side of the storage box, and the storage box or slider for moving the storage box up and down is provided with drive means and drive transmission means for giving a driving force. The upper end is fixed, the lower end of the supporting wire is fixed to a predetermined height of the wall surface or the guide rail, and the intermediate portion is locked to a locking member provided on the upper surface of the storage box. Composition and It was.

[0007]

When the storage box stored under the ceiling is lowered into the room, the driving means is driven in the descending direction. This drive is transmitted by the drive transmission means, and the storage box descends along the guide rails while the guide rails and the slider prevent the posture from changing in the horizontal direction. Then, as the storage box descends, the locking member moves downward along the supporting wire. That is, since the supporting wire is hung between the inside of the ceiling and the wall surface or the guide rail and is locked by the locking member, the weight of the storage box is
It is supported by the supporting wire, and the locking member moves downward while maintaining the weight supporting state. Therefore, the weight of the storage box is supported by the drive means and the supporting wire that are connected to the storage box or the slider, and the storage box is prevented from tilting forward or rearward and preventing vertical posture changes. To be done.

Next, when raising the storage box, the driving means is driven in the raising direction. This drive is transmitted by the drive transmission means to raise the storage box.
The guide rail and the slider prevent the posture from changing in the horizontal direction, and the supporting wire and the locking member support the weight of the storage box to prevent the posture from changing in the vertical direction.

This drive is transmitted to the deceleration mechanism 15 → the rotating shaft 14 → the hoisting drum 13, the raising / lowering wire 12 is fed out, and the storage box 9 is
The guide rail 6 and the slider 10 descend along the guide rail 6 while preventing the posture from changing in the horizontal direction.

When the storage box 9 descends, the balance rollers 20 and 21 move downward along the supporting wire 19. That is, since the supporting wire 19 is laid between the inside of the ceiling 3 and the wall surface 1 and is laid around the lower side of the first balance roller 20, the storage box 9
The weight of the front part of is supported by the supporting wire 19. Therefore, the storage box 9 is moved up and down with the front part supported by the supporting wire 19 and the rear part supported by the elevating wire 12, without causing forward tilting or rearward tilting.
The vertical posture change is prevented.

When the storage box 9 is lowered, for example,
When the lowering of the storage box 9 is stopped due to an obstacle such as biting an object in the guide rail 6, when the lifting wire 12 is unwound and sags, the weight sensor 1
In No. 1, the spring 11c extends more than a predetermined amount to turn on the sagging prevention switch 11g, and the drive motor 16 stops in response to this.

B) When the storage box is raised When the storage box 9 is raised and stored in the ceiling space 3, the drive motor 16 is driven in the upward direction. As a result, the raising / lowering wire 12 is wound up and the storage box 9 rises. Even during this raising, the guide rail 6 and the slider 10 prevent the posture change in the horizontal direction, and the supporting wire 1
9 and the first balance roller 20 support the weight of the front portion of the storage box 9, and the lifting wire 12 supports the weight of the rear portion of the storage box 9, thereby preventing vertical posture changes.

An example in which two supporting wires 19 are provided has been shown, but either one may be one.

Further, the drive motor 16 mounted on the mounting frame 8 is shown as the drive means, and the drive transmission means is
Although the lifting wire 12, the hoisting drum 13, the rotary shaft 14, and the speed reduction mechanism 15 are shown, the present invention is not limited to these.
For example, as the driving means, other means such as an actuator driven by hydraulic pressure may be used, the lifting wire 12 may be connected to the slider 10, and the lifting wire 12 may be stored in the storage box 9. May be connected to the front part or the central part of the storage box, the first balance roller 20 may be provided in the center or the rear part of the storage box 9, the drive means may be attached to the storage box 9, or the drive transmission means. May use other means such as a gear or a chain.

Further, in the embodiment, the example in which the two retractor devices 22 are provided on the left and right sides is shown, but only one retractor device 22 may be provided. In this case, the retractor device 22 itself is provided on one of the left and right sides or the front and rear sides of the storage box 9, the tip of the webbing 22a is fixed to the other of the left and right sides or the front and back sides, and the intermediate portion is supported at a position above the center of the storage box 9. If it is set, it is preferable in terms of balance.

Further, in the embodiment, the first balance roller 20 is shown as a member for locking the supporting wire 19, but
As the locking member, the important point is that the supporting wire 19 is accommodated in the storage box 9
For example, a tubular member or a hook-shaped member can be applied as long as the weight can be applied. The same applies to the second balance roller 21.
