BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIGS. 1 to 8.

As shown in FIGS. 1 and 2, the guide rails 4 which are vertically installed so as to face each other and the storage rail 9 inclined upward intersect each other, and the corner portion 2 of the storage rail 9 forms an R shape. In addition, a foldable door 7 is provided in which a part of the cutout portion 3 is provided below the guide rail 4 and sliding parts such as rollers 5 are attached to both sides of the door body 6 in the groove of the guide rail 4. A plurality of sheets are continuously provided in the vertical direction, and the door 7 is configured to be movable up and down by a driving means.

Specifically, when the doors 7 are raised (opened), each door 7 is raised by the driving means connected to the door 7 at the lowermost end, and the R shape of the upper end of the guide rail 4 and its shape. The mutation direction of each door 7 is sequentially changed by the notch 3 at the bottom,
It is adapted to be accommodated in the interior 8 of the storage part 1 top surface. Further, by making the entire surface of the door 7 fully open, not only is it easy to put in and take out stored items, but there is a feature that the space in front of the door 7 such as a hinged door or a folding door does not become a dead space.

Further, when the door 7 is raised (opened), the door 7 is stored above the front of the storage portion 1, and a cover is provided in the storage portion 1 to improve the appearance. Also, by changing the number of doors 7 and the guide rails 4, any storage unit 1
Therefore, the replacement work of the door 7 at the time of maintenance can be easily performed for each sheet.

As shown in FIGS. 3 and 4, the taper member 13 is provided at the upper end or the lower end of each door 7 to facilitate the change of the displacement when the door 7 is raised (opened). Members, which are tapered stepwise at the upper and lower ends of the frames attached to both sides of the door, are attached so as to engage with the respective doors. Then, by the R portion provided at the upper end of the guide rail 4 and its taper member, it is attached to the side surface of the door
The lower rollers 5, 5a of the individual rollers 5, 5a are easily separated from the guide rail 4. The door 7 is the lower door 7a
Is pushed up to be guided to the storage rail 9.

As shown in FIG. 4, a door drop prevention stopper 10 is provided in the notch 3 above the guide rail 4. When the door 7 is raised (opened), the lower roller 5a comes off the notch 3 of the guide rail 4 first. At this time, if there is nothing in the cutout portion 3, the door 7 will fall off from the cutout portion 3 under its own weight. In the system in which the door is stored by such a mechanism, a method of disposing a rail parallel to the storage rail 9 in the cutout portion 3 of the guide rail 4 is also conceivable.
In that case, the door 7 may be twisted by the two rails when the door 7 is descending (closed), which lowers the reliability of the lifting operation.

Therefore, as shown in FIG. 5, by arranging a member having the convex portion 16 at the tip of the two-stage slope, not only is the door 7 prevented from falling, but also when the door 7 is raised (when opened). ) Is also a fulcrum when pushed up from the lower door 7a. When the door 7 descends (closes), the lower roller 5a
Does not hit the member, and the convex portion 16 also plays a role of preventing falling.

A link 17 for connecting the door 7 is slidable. In the system in which the driving means is connected to the lowermost door 7 and the doors 7 are moved up and down, and at the same time each door 7 is put in and taken out from the storage rail 9, if each door 7 is independent (not connected), it is stored. It is conceivable that the doors 7 may not be interlocked with each other particularly when the rails 9 and the guide rails 4 are moved or when foreign matter is attached to the rails, especially when the doors 7 are lowered.

Therefore, as shown in FIG. 6, in order to solve the problem, side frames 12 having flanges at U-shaped openings are attached to both side surfaces of the door 7, and slidable shoes 18 are arranged therein. Link 17 with the member 17a fixed to the upper end of the lower door 7a and the side frame 12a.
By forming the doors, it is possible to connect the doors and improve the stability of the raising / lowering / storing operation of the doors.

As shown in FIG. 7, (a) shows the state before operation, in which the lower door 25 is the shoe 1 of the upper door 25.
Moved forward with the rotation of the link 17 centering on 8,
From the state of (b), the shoe 18 is attached to the side frame 12
It slides upward along the rails and the lower door 2
5 slides upward, (c) shows the state after the operation, and the upper door 24 is to be stored rearward. This operation is performed until the door 7 is housed in the upper part.

By providing the storage rail 9 with an inclination, the door 7
The reliability of the descending operation is improved.

As shown in FIG. 8, the upper and lower frames 1 of the door 7
A shield plate 20 that shields the upper part of the lower door 25 is provided at the lower end of the lower frame 23 of 9 to eliminate the gap 21 between the upper and lower sides of the door 7. If there is a gap 21 between the doors when the door 7 is closed, not only is insects intruded and the stored items inside the door 7 are visible, but also the appearance is not good. Therefore, in order to eliminate the gap 21, a shield plate 20 for shielding the upper part of the lower door 25 is provided at the lower end of the lower frame 23 of the upper and lower frames 19 of the door 7. When the door 7 is closed and the lower frame 23 of the upper door and the upper frame 22 of the lower door 25 are applied to define the position of the door 7, the gap 21 surely becomes zero. On the other hand, when the position of the door is defined by a taper member or the like, it is sufficient that the upper and lower frames 19 do not come into contact with each other due to variations in dimensions, but since the frame is formed, a gap 21 in the sense that the inside of the door 7 can be seen. Does not occur. Thus, the means for eliminating the gap 21 can be easily and inexpensively constructed, and can sufficiently deal with the dimensional variation of the door 7 position regulation.

[0027]

As described above, according to the present invention, the door can be opened and closed without any front and rear space, and it can be used in a fully open state without a door pocket etc. in the opened state. Can have an excellent design.
