By fitting them together, the rank mounting plate 8 is attached to the side frame 2 so as to be movable up and down. Further, 10 is a stopper piece projecting inwardly below the side frame 2, and 11 is a cushion rubber attached to the upper part of the stopper piece 10.

A flange-shaped stopper 12 is provided at the upper end of the rack mounting plate 8 described above.
is formed, and a long hole 13 is bored in the vertical direction.

Reference numeral 15 denotes an article storage shelf (hereinafter referred to as a rack), the side wall of the rack 15 is fixed to the rack mounting plate 8 described above, and the side wall of the rack 15 has holes corresponding to the long holes 13 of the rack mounting plate 8. Similarly, a vertically elongated hole 16 is bored at the position where the rack 15 is opened, and the front side of the rack 15 is opened, and a door 17 is hinged to the open part by a hinge 18.

Reference numeral 20 denotes an attachment plate attached to the chain 5 described above, and a rank support pin 21 is protruded from the attachment plate 20, and this rack support pin 21 is inserted into the elongated hole of the rack mounting plate 8 and the rack 15 described above. 13. Slide base 22 inserted through 16 and embedded in long groove 23 provided laterally inside rack 15
It is pivotally supported on the upper end of a door opening/closing lever 24 which is rotatably attached via a. Reference numeral 25 denotes a pivot pin protruding from the door opening/closing lever 24, and the pivot pin 25 is supported by a slide plate 26, and is attached to the slide base 2.
It is inserted into and engaged with the elongated hole 27 of No. 2.

The second plate is a plate cam attached to the inside of the door 17, and the door 17 is smoothly opened and closed by rolling a roller 24' which is pivotally supported on the top of the plate cam 24 at the tip of the door opening/closing lever 24. I try to do it.

The above-described fixed frame 1 is attached to, for example, a ceiling joist 31 via a groove-shaped fitting 29 and an L-shaped fitting 30, and is attached by fitting the upper part of the fixed frame 1 into the space of the ceiling. It is attached so that it can be raised and lowered.

In the figure, reference numeral 33 is a drive motor, and 34 is a sprocket to which power is transmitted from the drive motor 33, a chain 5 is hooked thereon, and the shaft of the upper sprocket 3 is driven.

Since the first embodiment is configured as described above, the drive motor 33 is driven to rotate the upper sprocket 3.
When the chain 5 is driven in the upward direction of the rack 15, the rack support pins 21 protruding from the attachment plate 20 attached to the chain 5 are connected to the rack mounting plate 8 and the vertical pins 21 drilled in the side walls of the rack 15. Directional long hole 1

(see figure).

Next, the drive motor 33 is reversely rotated to operate the chain 5 in the direction of lowering the rack 15.
The rack mounting plate 8, which is fixed to the rack I5 together with the rack 15, has its engager 9 engaged with the slide rail 7 of the side frame 2, so that the rack mounting plate 8 is lowered, and as a result of the lowering, the rack mounting plate 8 is lowered. The brim-shaped stopper 12 at the upper end of the rack 15 comes into contact with a stopper IO projecting inside the lower part of the side frame 2, and the rack 15 is forcibly stopped from descending.

Even if the rack 15 is stopped as described above, the chain 5 continues to descend, so the rack support pin 21 protruding from the attachment plate 20 attached to the chain 5
The tip of the rack support pin 21 descends through the vertical long hole 13 of the rack mounting plate 8 and the vertical long hole 16 formed in the side wall of the rack 15, which is bored at the same position. The door opening/closing lever 24 , which is pivotally supported by the door opening/closing lever 24 , is lowered, but the lever rotation fulcrum pin 25 , which protrudes from the approximate center of the door opening/closing lever 24 , is attached to the slide base 22 embedded in the side wall of the rack 15 . Since it is inserted into the elongated hole 27, the pivot pin 25 of the lever 24 slides laterally as the door opening/closing lever 24 is lowered, and as a result, the door opening/closing lever 24 rotates. Then, the roller 24' at the tip operates to open the door 17 that comes into contact with it.

Further, the above-described lowering of the rack 15 and opening of the door 17 will be explained using the second embodiment shown in FIG. 4. In the second embodiment shown in FIG. The lower stopper was formed at the upper end of the plate 8 and was formed by protruding from the lower inner side of the side frame 2. However, in the second embodiment, the front and rear longitudinal upper ends of the rack 15 correspond to the upper stopper. Flange section bent outward 15. , 15. The flange portion 151
, 15. is used as an upper stopper, and the lower end of the front and rear longitudinal direction of the fixed frame 1 is bent inward to form a stopper 1. which corresponds to a lower stopper. ．． 1. And so.

The second embodiment is the same as the first embodiment in other respects, and the same reference numerals are used for the same members. Further, in the second embodiment, in order to explain the lowering of the rack 15 and the opening/closing operation of the door 17 after the lowering is stopped, the minus part is omitted for ease of understanding.

Further, although only one side is shown in FIG. 4, the same configuration is provided on the other side.

FIG. 4(a) shows a state in which the rack 15 is supported and lifted by rack support pins 21 protruding from an attachment plate 20 attached to the chain 5.

In order to achieve the above state, the rack support pin 21 inserted into the vertical elongated hole 16 bored in the side surface of the rack 15 is projected from the attachment plate 20 attached to the chain 5. Therefore, the rack 15 is lifted and raised by the drive of the chain 5, and about half of it is housed inside the fixed frame 1.The rise is stopped by the top dead center limit switch 35, and the goods are stored in the rack 15. It is stored in the same condition.

Next, for example, when the lower movement button is pressed, the chain 5 is driven in the opposite direction, the attachment plate 20 attached to the chain 5 moves downward, and the rack support pin 21 protruding from the attachment plate 20 moves downward. Therefore, the rack 15 is also lowered, and the upper flange 15. of the rack 15 is lowered.
, 15. However, the stopper 1 formed at the lower end of the fixed frame 1. ．． 1. , and the lowering of the rack 15 is forcibly stopped (see FIG. 4(0)).

Even if the lowering of the rank 15 is forcibly stopped by the stopper as described above, the chain 5 is still being driven, and the attachment plate 2 attached to the chain 5
0 continues to descend, and at the same time the rack support pin 21 protruding from the attachment plate 20 also descends within the longitudinal elongated hole 16 drilled in the side surface of the rack 15, but at this time,
The tip of the rack support pin 21 is connected to the door opening/closing lever 2.
Since it is pivotally supported at the upper end of the door opening/closing lever 24, it descends together with the door opening/closing lever 24. However, a fulcrum pin 25 for rotating the lever is protruded from approximately the center of the door opening/closing lever 24, and the fulcrum pin 25 is inserted into a horizontal long hole 27 in the side wall of the rack 15. 27 in the horizontal direction via a slide plate 26, the door opening/closing lever 24 is lowered by the rack support pin 21 on the one hand, and blocked by the fulcrum pin 25 on the other hand. Therefore, the door opening/closing lever 24 is rotated using the fulcrum bin 25 as a fulcrum, and the door 17 of the rear 15 is opened by the hinge 18 by the roller 24' attached to its tip. When it opens, the bottom dead center limit switch 36 is turned off and the descent of the lane 5 is stopped, and the articles stored in the rank 15 can be easily taken out or stored safely.

In addition, the horizontal C long hole 2 bored in the rack 15 described above.
7 is an elongated hole because the swing of the fulcrum bin 25 changes when the rack support bin 21 is lowered and the door closing lever 24 is opened and closed. When the force increases by 15 degrees and the door opening/closing lever 24 is directed downward, the door 17 also follows the roller 24' attached to the tip of the lever 24 and closes.

As mentioned above, book 1. In the second embodiment, the door 17 is opened when the rack 15 is lowered, and the door 17 is closed when the rack 15 is raised, all in one motion.

Then, as shown in FIG. 5, for example, using the space (behind the ceiling) 42 between the ceiling 40 and the second floor 41, a storage shelf device is installed so that about half of the rank 15 is fitted into the space, and the storage shelf device as described above is installed. If you raise and lower the rack 15,
When the rack 15 is raised, the upper part of the rack 15 is hidden in the space (behind the ceiling) 42, and when it is lowered, it remains hidden! This allows items to be taken in and out easily. Also,
As described above, the rack 15 does not necessarily need to be placed all the way to the ceiling, and such a box may be attached to the ceiling of the room.

〔Effect of the invention〕

The movable hanging shelf according to the present invention forcibly stops the lowering of the rack that can be raised and lowered, and simultaneously pushes down only the door opening/closing lever, and at the same time as this depression, the door opening/closing lever is moved using the fulcrum bin as a fulcrum. This rotation causes the tip of the lever to open the rack door, and as the rack rises, the door opening/closing lever rotates in the opposite direction to close the door. Since the rack is closed, it is possible to use the space when installing the rack with the rack facing upward, which contributes to effective use of the space in the room.
