Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a tier structure in which a plurality of shelves, which are vertically supported by a link mechanism, can be stored in a storage portion or can be displayed by a single operation.

2. Description of the Related Art As a conventional ladder structure, there are a pair of support frames on both sides,
Since a plurality of shelves are supported in a staircase shape so as not to overlap with each other, there is a drawback that the entire depth becomes deep and space saving cannot be achieved. Further, in Japanese Patent Laid-Open No. 56-76913, the middle position of the tilt lever is pivotally attached to the upper part of the supporting rod, and the tilt lever is provided with a horizontal plate. However, the horizontal plate is maintained in a horizontal position. Since it is necessary, there is a drawback that the structure becomes complicated. In addition, the doll placed on the hinadan is exposed as it is when it is stored, so it is necessary to cover the outside.

[Problems to be solved by the device]

The present invention was devised as a result of earnest research in view of these problems.The main problem is to develop a parallel link mechanism when used and display it in a staircase. The present invention provides a tiered structure with a simple structure in which the doll can be folded and stored, and the split hair can cover and store the doll from the outside.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides (a) a pair of support columns at the front and rear, (b) a pair of support members slidable in the vertical direction on each of the pair of support columns, (c) the pair. A pair of link rods, which are pivotally attached at their upper ends to be provided in parallel with each other in the longitudinal direction, are provided in the pair of link rods in parallel with each other at upper and lower stages. Provide a shelf portion pivotally attached to the rod, (e) provide a split bristle that covers the upper surface of each shelf plate and has a tip that hangs down and extends to the upper surface of the lower shelf plate, (f) the lower end of the link rod is the strut side The technical measures are taken to move to a storage position where the shelves are substantially vertically overlapped with each other and to a deployed position where the link rod is moved forward of the support so that the shelves are stepped.

[Action]

Since this invention is configured as described above, since the link frame is a parallel link mechanism, if the lower part is pulled out from the storage part forward, each shelf plate will not overlap in the front and back because of different shelves, Hina dolls can be displayed. Then, when the lower part of the link frame is put back into the storage part, the shelves will overlap vertically, and the dolls on the shelf will push through the split ridges and be stored in the storage part, so the outside will be separated by the split ridges. To be covered.

【Example】

A preferred embodiment of the ladder structure of the present invention will be described with reference to the drawings. 1 and 4 are schematic views showing the configuration of the tiered structure from the side, and FIG. 2 shows the plane thereof. The storage unit 2 of the stepped shelf 1 is framed by arranging columns 3, 3, 3 and 3 standing upright at four corners so as to have a rectangular shape in a plane. A pair of link frames 5 and 5 are pivotally attached to the upper portions on both sides of the storage portion 2 in the width direction via supports 4 and 4. The link frame 5 includes link rods 5A and 5A that are parallel to each other in the front and rear.
Between the plurality of shelf support members 5B, 5 at predetermined intervals in the vertical direction.
B ... is laid horizontally and is pivotally attached to the link rods 5A, 5A. In addition, casters 7, 7 are respectively arranged at the lower end of each link frame 5 in the front-rear direction via a laterally U-shaped leg body 6. The support tool 4 is configured to be slidable up and down along the link rod 7, and in this embodiment, as shown in the plan view of FIG. The protruding piece 4A is projected outward, and the upper end edge of the link rod 5A of the link frame 5 is pivotally attached to the protruding piece 4A by a bolt 4B. Further, the shelf receiving plate 5B is pivotally mounted in parallel with the pair of link rods 5A, 5A so that it is always horizontal with respect to the support 4. Then, shelf plates 8, 8 ... Are hooked and placed on the ends of the rack support members 5B at the same high positions of the left and right link frames 5, that is, at the portions projecting from the front link rods 5A. Make up part. In this embodiment, the shelf portion is a combination of shelf receiving material and shelf plate. However, a plate-like shape in which the leading ends of the shelf receiving materials facing each other in the width direction are continuously connected in series is defined by a shelf board portion (not shown). It may be integrally formed as a shelf. According to the stepped shelf configured as described above, when used, the articles are displayed on the shelf plates 8, 8 ... And stored in the storage position where they stack vertically as shown in FIG. When displaying, if the lower part of the link frame 5 is pulled out forward from the storage part 2 as shown in FIG. 4 by the parallel movement, the respective shelves 8, 8 ... Can be easily pulled out in a stepwise manner by the casters 7, 7. Can be displaced to the deployed position, and in this case, the supports 4 and 4 can be guided and lowered by the columns 3 and 3. In the figure, reference numeral 9 is a stopper that is integrally provided on the support column 3 and abuts against the supporting tool 4, and restricts the downward sliding of the supporting tool 4 and fixes the use position. After the articles and the like are displayed in this way, when the link frame 5 is not used or when it is desired to use the space widely, the lower part of the link frame 5 is pushed toward the storage section 2 so that the link frame 5 is placed on the shelf plate 8. The article can be stored in the storage unit 2 while being placed. Note that the present invention is not limited to the above configuration, and design changes can be appropriately made. For example, the support tool 4 may be fixed rather than vertically slidable. In such a case, the legs 6 and 6 are long and foldable, and are folded when the link frame 5 is put into the storage part 2, and folded when the lower part of the link frame 5 is pulled out to the front of the storage part 2. The legs 6 and 6 which were described above are made to stand up and the link rods 5A and 5A of the link frame 5 of the link frame 5 are supported obliquely. FIG. 5 shows an embodiment in which the tier structure of the present invention is used for the tier 1. In this case, the structure of the storage unit 2 and the structure of the link frame 5 are the same as those in the above-described embodiment, and therefore, the same components are designated by the same reference numerals and their description is omitted. In this case, a split bristle M is provided on each shelf 8. That is, the split bristle M covers the upper surface of each shelf 8 and hangs down at the tip and extends to the vicinity of the upper surface of the next lower shelf 8. In the case of the lowermost shelf plate 8, it hangs down to the position of the caster 7. Since it is configured as described above, in the deployed position shown in FIG. 5, the divided ridges M are as if one continuous ridge was laid in series on each of the stepwise shelf plates 8, 8, .... As can be seen, at the storage position, a doll or the like passes through the split bristle M provided on the upper shelf 8 and is housed between the shelves that are vertically stacked on the inside thereof. At this time, when viewed from the front, the divided hair follicles M of the chick stage 1 are located as if they were hair follicles hanging in a series in the vertical direction.

[Effect of device]

Since this device uses the parallel link mechanism as described above,
The link frame can be pulled out from the storage section for display while the dolls are still placed on the shelf board, and it can be pushed back into the storage section as it is for storage, effectively utilizing the space required for installation. Can be extremely beneficial. Furthermore, the stored chick dolls pass through the split ridges and move back to the storage position, and the split ridges can cover the outside, so that the foldability is excellent.
