Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a pull-out rack for storing articles.

[Conventional technology]

In factories, warehouses, etc., in racks in which shelves on which goods are placed are supported so that drawers can be moved freely, the vertical depth dimension is formed to be approximately the same as the depth dimension of the rack body, thereby maximizing the goods storage area on the shelf, and Japanese Utility Model Application Publication No. 56-20542 discloses a prior art in which the rear end of the shelf can be pulled out to the front of the rack body in order to load articles on the innermost part of the shelf using a chain block or the like. ,
A so-called double suspension was provided in which an intermediate rail was provided between the shelf rails on both the left and right sides of the shelf and the main body rails on both the left and right sides of the rack body.

[The problem that the idea attempts to solve]

Such a double suspension configuration has the disadvantage that the structure is extremely complicated and the cost is also high.

To overcome this drawback, the prior art 50−31236
In the publication, the rear part of the main body rail attached to both the left and right sides of the rack body is formed into an upwardly curved shape,
An extension piece that can tilt only upward is pivotally attached to the rear end of the shelf rail attached to the left and right sides of the shelf, and when the shelf is pushed in, the rear ends of both extension pieces tilt upward along the curved part of the main body rail. The configuration is disclosed.

However, according to this configuration, the rear curved portion of the main body rail must be located within the rack body, and the depth of the shelf must be shortened by a depth corresponding to the depth of the curved portion. The ratio of the storage area of the shelf to the depth of the rack body becomes low, resulting in poor storage efficiency.

In addition, it is necessary to have an extension piece at the rear end of the shelf rail that is rotatable and tilts only upward.Furthermore, when the shelf is fully pulled out by its depth, the left and right extension pieces can be used to hold the shelf. In order to support the structure so that it does not tilt downward, special measures are required, making the structure complicated.

The present invention solves these problems with a simple configuration.

[Means to solve the problem]

Therefore, the present invention provides a pair of front and rear supports on the left and right side frames of the rack body with longitudinal rails facing each other inwardly in the front and rear directions, and supports the shelf between the two rails so that the shelf can be freely drawn back and forth. In such a rack, the rear ends of both of the rails are made to protrude rearward by an appropriate amount from the pillars that support the rear portions of the respective rails, and support rollers that support the left and right sides of the shelf are provided inside the left and right side frames of the rack body. The depth dimension of the shelf is formed to be approximately the same as the depth dimension between the pair of front and rear supports, and arms of appropriate lengths are protruded rearward along both the rails on both left and right sides of the rear end of the shelf, and each arm The rack is provided with rollers that can come into contact with each of the rails when the shelf is pushed into the rack body.

[Functions and effects of the invention]

In this way, in this invention, both the left and right sides of the shelf are supported by support rollers inside the left and right side frames of the rack main body.
In addition, since the rollers of the left and right arms that protrude rearward at the rear end of the shelf contact the rails on the rack body, the shelf will not tilt downward at the front even when the shelf is fully pulled out. Moreover, the shelf support structure is extremely simple compared to something like a double suspension.

Even when the shelf is completely pushed into the rack body, the shelf itself is located between the pair of front and rear supports on the left and right side frames, and only the rail that extends horizontally and the arms that protrude from the left and right rear ends of the shelf are the only parts of the rail. It only protrudes rearward from the struts that support the rear part, and the rack body does not change even if it is a single-row rack that pulls out the shelves forward, or a double-row rack that pulls out the shelves from both sides of the rack body. The area of the shelf relative to the rack body can be increased by making the depth dimension between the front and rear supports of the rack body substantially the same as the depth dimension of the shelf without making the rack body bulky.

Furthermore, as mentioned above, the shelf can be completely pulled out from the rack body, and the shelf can be supported reliably and approximately horizontally by both arms, so the entire shelf can be pulled out from the rack body. This has the effect of making it extremely easy to pull out and place items on the entire shelf, or conversely to unload items that have been placed on the entire shelf, and to increase the effective storage space of the rack.

〔Example〕

Next, an embodiment of the present invention will be described. Reference numeral 1 indicates front and rear supports 2, 2' having a rectangular cross section, etc.
This figure shows a rack main body in which side frames 4 connected to each other are erected at appropriate distances from each other to the left and right via cross beams 5 in the frontage direction. Reference numerals 6, 6, 6 are shelves arranged in multiple stages above and below on the left and right side frames 4, 4 of the rack main body 1,
Each shelf 6 is supported by rails 7, 7, which will be described later, so that it can be freely drawn back and forth.

The rails 7, 7 are formed in a U-shape in cross section and are disposed facing the sides of the shelf 6 so as to guide and support the left and right edges of the shelf 6 in the front and back direction.
7 are arranged substantially horizontally inside the left and right side frames 4, 4 at the same height, facing each other inwardly, and the respective rails 7 are provided at the front and rear of the brackets having an L-shaped cross section or the like (Fig. (not shown), the front and rear struts 2,
2', the rear protrusion 7' of each rail 7 is provided to protrude rearward by an appropriate distance L1 from the rear end face of the rack body 1. Support rollers 8 are provided on the left and right front brackets, respectively, to support the lower surfaces of the left and right sides of the shelf 6.

Reference numerals 9, 9 denote arms having a U-shaped cross section or a rectangular cross section, and the arms 9, 9 are provided to protrude rearward from both left and right sides of the rear end of each shelf 6, respectively.
The rear end portion is provided with rollers 10 that fit into and rotatably abut on each of the rails 7, so that when the entire shelf 6 is pulled out from the rack body 1, each shelf 6 touches both of the support rollers 8. , 8 and both arms 9, 9 to be supported substantially horizontally.
When the rack body 1 is pushed into the rack body 1, the arms 9 and rollers 10 are housed in the rearwardly projecting portions 7' of the rails 7 from the rack body 1.

The arms 9 may be formed by integrally protruding the rear end portions of the left and right side members of the shelf 6 from the rear end surface of the shelf 6, or alternatively, the arms 9 may be formed separately from the side members. It may be done.

In the above configuration, the following procedure may be used to store articles in the rack. That is, by pulling the shelf 6 forward from the rack main body 1, the left and right arms 9, 9
part in the rails 7, 7, thereby pulling out the entire front shelf. In this case, the arms 9, 9 on both the left and right sides of the rear end of the shelf 6 have the lower surfaces of their front ends touching the upper ends of the support rollers 8, 8 at the two locations on the front support 2, and the upper ends of the rollers 10, 10 at the rear end. Both rails 7,
In other words, the shelves 6 are supported substantially horizontally by contacting the lower surfaces of the top plates (not shown) of the shelves 6 and 7, respectively.
It is supported approximately horizontally on the rack body 1 by 9.

Next, the article 12 lifted by the chain block 11 may be placed on the upper surface of the pulled-out shelf 6. In this case, since the entire shelf 6 protrudes outward from the front of the rack body 1, the shelf 6 is placed above the shelf 6. There are no obstacles at all, so it is very easy to place the article 12 on the top surface of the shelf 6. Also, when the article 12 is placed on the shelf 6, the shelf 6 tends to tilt diagonally downward due to its weight. However, since the rollers 10, 10 of the arms 9, 9 come into contact with the lower surfaces of the top plates of the rails 7, 7, the shelf 6 is prevented from tilting, and the articles 12 are not placed on the upper surface of the shelf 6. Even in the placed state, the shelf 6 is supported substantially horizontally by the rack body 1.

After placing the articles 12 on substantially the entire upper surface of the shelf 6, the shelf 6 may be pushed into the rack body 1. Conversely, in order to take out the articles stored in the rack body 1, it is sufficient to pull out the entire shelf 6 from the rack body 1, and then lower the articles 12 on the upper surface of the shelf 6 using, for example, the chain block 11. ,
Since the entire shelf 6 protrudes outward from the front of the rack body 1, there are no obstacles when unloading the articles 12, and as a result, the work of taking out the articles 12 can be done extremely easily.

FIG. 3 shows another embodiment of the present invention, which is a so-called double-row rack in which shelves 6, 6 can be pulled out from both the front and rear sides of the rack body 1. The two rack bodies shown are
This corresponds to a structure in which the pillars 2 are then placed back to back so that they are shared.

That is, 1 has three pillars 2, each having a rectangular cross section, etc.
2', 2'', that is, a central column 2', and columns 2, 2'' on both sides in the depth direction based on the central column 2', are connected to each other by depth cross beams 3, 3 with appropriate distance from each other. , 4 indicate rack bodies which are erected at appropriate distances from each other on the left and right via cross beams (not shown) in the frontage direction.

Reference numerals 6, 6 are front and rear shelves arranged in two rows in the depth direction between the left and right side frames 4, 4 of the rack main body 1 in multiple stages above and below. They are supported by the rails 7, 7 so that they can be pulled out in opposite directions, and are configured so that the rear end of each shelf 6 does not protrude in the depth direction from the central support 2' when pushed into the rack body 1. It is configured.

The protrusions 7'7' and 7'7' at the rear ends of the left and right rails 7, 7, 7, 7 are connected to the central support 2'.
so that they protrude in opposite directions based on
In appropriately arranging the central pillar 2' and the pillars 2 and 2'' which are erected at appropriate distances in front and behind it, one of the left and right rails 7, 7 and the other left and right rails 7, 7 are arranged as appropriate. The mounting height position relative to the support column is shifted by an appropriate dimension to provide a step, and the protrusions 7', 7' of the two rows of rails 7, 7, 7, 7 are moved appropriately in the longitudinal direction of the opposing rails 7, 7. The support rollers 8, 8 are provided so as to overlap by a dimension L2. Support rollers 8, 8 for supporting the lower surfaces of the left and right sides of the shelves 6, 6 are provided on each of the pillars 2, 2'', etc., respectively.

Reference numerals 9 and 9 denote arms that protrude rearward on both sides of the rear end of each shelf 6, respectively.A roller 10 is provided at the rear end of each arm 9, and the entire shelf 6 can be mounted on the rack body. When you pull out from 1, this roller 1

When the rack body 1 is pushed into the rack body 1, each arm 9 is housed in a protruding portion 7' of each rail 7 in the depth direction from the central support 2'.

In this configuration, the articles 12 can be placed on the two rows of shelves 6, 6 in the front and rear rows in the depth direction and stored in the racks as follows. That is, the two rows of shelves 6, 6 are each pulled out from the rack main body 1 in opposite directions, and the articles 12 are placed on the upper surface of each shelf 6, 6 in the same manner as in the embodiment described above.

In this case, the two rows of shelves 6, 6 pushed into the rack body 1 are connected to the central column 2' of the rack body 1.
does not protrude in the depth direction from the front and back 2.
Since the rows of shelves 6, 6 do not overlap each other, articles 12, 12 can be placed on the entire upper surface of each of the two rows of shelves 6, 6.

While ensuring that the two rows of shelves 6, 6 do not overlap each other, the two rows of rails 7, 7 in the depth direction,
Since the protrusions 7', 7' at the rear ends of 7, 7 are vertically interlocked with each other, they do not get in the way even if they protrude from the central pillars 2', 2' by a dimension L2, and the dimension L2
Since the depth dimension L of the rack body 1 can be reduced, the floor space of the room can be used more effectively than when two racks in a single row are arranged back to back.

In addition, the rack has one central pillar 2' on each side,
Since the racks are arranged back to back in two rows via 2', it is difficult for the racks to fall over in the depth direction.
In other words, the rack becomes stable.

Furthermore, since two rows of racks are formed by using one center column 2'2' on the left and right in common, the number of parts is reduced compared to arranging two racks in a single row back to back, reducing costs. It is possible to achieve this goal.
