Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shelf device in a cracker for storing articles.

Recently, in factories, warehouses, etc., in order to make effective use of high-altitude spaces in factories, etc., racks for storing goods are made as high as possible, and shelves are installed on the racks in multiple tiers to store goods on them. Things are becoming more and more common. If a top plate is fixed to the top surface of each shelf and the top surface of the shelf is covered, large and small items can be placed and stored, but this shelf is located higher than the worker's eye level. In some cases, it is not possible to distinguish the items on the top of the shelf from below, and for this reason, it is difficult to climb up using a ladder, or to prepare a step stool and climb onto the step to reach the item on the shelf. It was extremely troublesome to have to check this.

Therefore, in the present invention, vertically penetrating gaps are formed in the frames of shelves provided in multiple levels above and below the rack body, and when large items are placed on the shelves, the presence or absence of the items can be confirmed from below the shelves through the gaps. At the same time, we aim to reduce the weight of the shelf and the entire rack, and at the same time, by attaching a top plate that closes the entire gap to the upper surface of the shelf in a removable manner and immovable in horizontal directions such as left and right, it is possible to reduce the size of the shelf. It is designed so that other items can be placed safely.

Next, the present invention will be explained based on an example.
This figure shows a rack main body in which side frames 4 are connected at 3 and are erected at appropriate distances from each other to the left and right through side rims 5, 5 in the opening direction.

Reference numerals 8, 8, and 8 indicate shelves that are arranged vertically in multiple stages between the left and right side frames 4, 4 of the rack main body 1, and are movable back and forth, and 6, 6 guide the left and right sides of the shelf 8 in the front and back direction. The supporting rails are U-shaped in cross section, and both rails 6, 6 are arranged substantially horizontally inside the left and right side frames 4, 4, facing each other at the same height position, and each rail 6 has a cross section L at the front and rear. Bracket 7 for character shapes, etc.
7, and both brackets 7, 7 are brought into contact with the side surfaces of the front and rear struts 2, 2' and fixed with bolts or the like.
In addition, the left and right front brackets 7 are provided with the shelves 8, respectively.
Support rollers 13 are provided to support the lower surfaces of the left and right sides.

Each of the shelves 8 includes a pair of left and right depth members 9, 9 each having a U-shaped cross section, each of which has a rectangular frame in plan view and has a wheel 12 at the rear that fits into both the rails 6, 6.
and a pair of front and rear horizontal members 10, 10 connecting both depth members 9, 9 on the left and right. In the embodiment, each horizontal member 10 is formed into a U-shaped cross section, and the upper and lower horizontal free ends are bent inward perpendicularly to form the tongue piece 1.
1, 11' are provided, and each tongue piece 11, 11' of both horizontal members 10, 10 is arranged so as to be inside the shelf and connected to the front and rear ends of both depth members 9, 9.

Then, intermediate members 10', 10', 10' having the same shape as the horizontal members 10, 10 are arranged parallel to each other and spaced at an appropriate interval l in the front and back midway parts of the left and right depth members 9, 9 of the shelf 8. By arranging it, a gap S is formed that passes through the shelf 8 from above and below.

Incidentally, instead of the intermediate members 10', a gap may be formed by arranging an intermediate member in the pair of front and rear horizontal members 10, 10 approximately parallel to the depth members 9, 9 at an appropriate distance.

Reference numeral 14 indicates a top plate having a rectangular shape in a plan view and having approximately the same shape as the shelf so as to be removably placed on the upper surface of the above-mentioned arbitrary shelf 8 and cover the entire gap S; 17 indicates a shelf 8 in the above-mentioned gap S; A connecting body is shown that is disposed from below and is detachably attached to the lower surface of the top plate 14 via bolts 20, and is configured to be latched to the shelf 8 so as not to be able to move upward.

As shown in the illustrated embodiment, the case in which the top plate 14 is attached to the shelf 8 with four connecting bodies 17 so as not to be movable in the left and right directions and front and back thereof will be described in detail. The locking claw 18 in the connecting body 17 is formed by bending one side downward substantially vertically and further bending the tip upward to provide the locking claw 18 that opens upward. The opposite end is bent upward to provide a contact portion 21 that contacts the lower surface of the top plate 14.

19 is a screw hole for fastening the connecting body 17 to the top plate 14 with a bolt 20;
The position 9 is located approximately at the center of the connecting body 17 with a dimension 11 from the left and right end surfaces 22, 22' which are approximately perpendicular to the locking pawl 18.

On the other hand, the top plate 14 has a portion corresponding to the gap S between the horizontal member 10 at the front end of the shelf 8 and the intermediate member 10' adjacent thereto, and a portion corresponding to the gap S between the horizontal member 10 at the rear end and the intermediate member 10' adjacent thereto. A pair of bolt mounting holes 16, 16, 16, 16 are inserted into recesses 15, 15, 1 into which the head of the bolt 20 sinks from the upper surface of the top plate 14, respectively, at locations corresponding to the gap S, spaced appropriately on the left and right.
5, 15. At this time, the positions of the pair of left and right bolt mounting holes 16, 16 in the front part are such that the left or right end surface of each connecting body 17 to be attached to these locations comes into contact with the inner surface of the aforementioned or right depth members 9, 9. Position it where possible.

With this configuration, the top plate 14 is placed on the upper surface of any of the shelves 8, and the connecting bodies 17 are inserted from the lower surfaces of the S and S shelves 8 in the gaps S and S at the front and rear positions of the shelves, and the connecting bodies 17 are engaged with each other upwardly. The retaining claw 18 is engaged with the downward tongue piece 11 of the horizontal member 10, and the connecting body 17
When the bolts 20 are tightened between the top plate 14 and each connecting body 17 with the contact end 21 of the top plate 14 in contact with the lower surface of the top plate 14, the top plate 14 is attached to the shelf 8 without being able to move up and down. , and the connecting bodies 17, 17 in the front and rear positions
The upward locking claws 18, 18 of the horizontal members 10, 10
The top plate 14 comes into contact with the vertical surfaces of the downward facing tongue pieces 11, 11, and cannot move back and forth with respect to the shelf 8.

Further, the left end surface 22 of the left connecting body 17 at the front is in contact with the inner surface of the left depth member 9, and the right end surface 22' of the right connecting body 17 is in contact with the inner surface of the right depth member 9, so that the top plate 14 is in contact with the shelf 8. However, it becomes impossible to move in either the left or right direction.

Note that 23 and 24 are edges projecting upward from the front and rear ends of the top plate 14.

In addition, in the present invention, the connecting body 17 is attached to the top plate 14 at the front or rear side member 10 of the shelf 8.
Alternatively, the intermediate member 10' may have two locations on the left and right, or may have three locations, such as two at the front and one at the rear, and two locations at diagonal corners, such as a front left position and a rear right position of the shelf. You can also do that. Further, the upward locking pawl 18 of each connecting body 17 may be configured to engage with a downward tongue piece or the like provided on the depth member 9 instead of the horizontal member 10.

As described above, according to the present invention, each shelf provided in multiple stages on the rack main body is configured into a frame body having a rectangular shape in plan view with a pair of left and right depth members and a pair of front and rear horizontal members connecting these to the left and right, and By arranging a plurality of intermediate members extending in the depth direction or the lateral direction of the rack main body with gaps of appropriate dimensions between each intermediate member, a gap that passes through the top and bottom of the shelf can be formed. If the items to be placed on the shelf are large and there is no risk of the items falling through the gap, place the items on the shelf from below the gap, even if the shelf is higher than the worker's eye level. In other words, there is no need to climb up a ladder or the like to check the items on a shelf at a high place as in the past, which is extremely convenient. On the other hand, if the items placed on the shelf are small and there is a risk that the items placed on the shelf may fall through the gaps in the shelf,
It is sufficient to place the top plate on the upper surface of the shelf at that location, and since the top plate can be detachably attached to the shelf as required, it is possible to reduce the weight of the shelf itself and the weight of the rack as a whole.

Since the connecting body, which is removably attached to the lower surface of the top plate with bolts, is disposed in the gap inside the shelf frame, it is extremely easy to engage and disengage the connecting body and the shelf frame. Moreover, since the connecting body is rectangular in plan view and has an upward locking pawl on one side, even if the bolts between the top plate and the connecting body loosen somewhat, the top plate will not come off upward, and the connecting body will Since the side surfaces are in contact with the inner surface of the shelf frame, the top plate will not move left or right or front and back relative to the shelf, eliminating any wobbling, and there is no risk that the connecting body will rotate together when the bolts between the connecting body and the top plate are tightened. As a result, the work of bolting the top plate and the connecting member can be done extremely easily.
