DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to an assembly structure of a net-like assembly shelf in which a rectangular back frame, a sleeve frame, and a shelf frame that constitute an article storage shelf are connected to each other. Also, the present invention relates to an assembly structure of a net-like assembly shelf in which similar assembly shelves can be easily connected to the outside of the sleeve frame.

Conventional technology Conventional non-installed mesh shelves used in factories, warehouses, etc.
Generally, unit mesh shelves formed by connecting a square back frame, both sleeve frames and a shelf frame are back-to-back or arranged by a required number of adjacent shelves. Therefore, in the case of back-to-back or adjacent arrangement as described above, there is a problem that the back frame and the sleeve frame are doubled, the equipment cost is increased, and the floor area is unnecessarily occupied. There is a problem in that it requires a large floor area to store and is inconvenient to move.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention constructs a unit assembly shelf by using an assembly structure in which a back frame, both sleeve frames, and a shelf frame can be easily engaged and disengaged, and the back side of the unit assembly shelf and the outside of the sleeve frame. Another object of the present invention is to solve the above-mentioned problems in the related art by making it possible to easily add a unit assembly shelf that shares the back frame and the sleeve frame.

Means for Solving the Problems In order to solve the above problems, the present invention proposes that a back frame having horizontal bars of a rectangular mesh frame and having horizontal bars arranged at the same height, a sleeve frame, and a shelf frame composed of a rectangular mesh frame to be mutually connected. An assembling structure of a net-like assembly shelf which is formed to be engageably and disengageably engaged, wherein upward hooks projectingly formed at opposite ends of each horizontal bar of a back frame supported upright on the floor are provided with two sleeve frames. Engage the downward hooks projectingly formed on one side of each step horizontal bar, and engage the downward hooks projectingly formed on both sides of the shelf frame on the lateral bars of both sleeve frames, respectively. It is characterized by an assembly structure in which a detent member is fixed and an upward hook projectingly formed on a rear portion of a shelf frame is engaged with a horizontal bar of a back frame.

Further, vertical bars and horizontal bars made of steel are welded to each other in a lattice shape to the back frame and sleeve frame, and the protruding ends of the horizontal bars are bent to form upward hooks and downward hooks. Two downward facing hooks of the sleeve frame are engaged together with the adjacent back frame vertical bar, and downward hooks are formed at the left and right asymmetrical positions on the rear part of the shelf frame, and also on the back side of the back frame. A similar net-like assembly shelf can be connected in series.

Further, in order to connect other assembly shelves by contacting the outside of the sleeve frame, an upward hook is formed only at one of the opposite ends of each horizontal bar of the back frame, and the horizontal bar of the back frame is connected to this hook. Make sure that it does not interfere with the adjacent hooks of the next back frame, and that the upward hooks on the rear of the shelf frame are located at asymmetrical positions so that they do not interfere with the upward hooks of the shelf frames of the mesh shelves that are linked to the back frame back. In addition, the front and rear positions of the downward hooks on the side of the shelf frame are made different from each other to avoid the interference between the downward hooks of the adjacent shelf frames.

Action When the downward hooks of both sleeve frames are engaged with the upward hooks of the back frame that are orthogonally supported on the floor, half the weight of each sleeve frame is applied to the back frame, and the upward hooks and the downward hooks engage at right angles to each other. The back frame and the sleeve frame in the position are held in a self-supporting state.

Therefore, by hooking the upward hook of the shelf frame to the horizontal bar of the desired height of the back frame from below and engaging the downward hooks on both sides of the shelf frame on the horizontal bars of both sleeve frames, the shelf frame will be It is supported by the sleeve frame to prevent back and forth movement and left and right movement. Even if an operator rides on the front part of the shelf frame in this state, the upward hook at the rear part of the shelf frame is locked to the horizontal bar of the back frame and the shelf frame does not roll forward and upward, which is safe.

Further, even if the entire assembly shelf is tilted in the left-right direction in this state, the upward hook of the back frame does not engage with the downward hook of the sleeve frame and the back frame and the sleeve frame are not disengaged from each other. Therefore, the unit assembly shelf assembled in this way has a strong connection even if only the vertical engagement of the hooks is engaged.

In order to connect another assembly shelf to the back side of the unit assembly shelf, engage the downward hooks of the different sleeve frames with the upward hooks on both sides of the existing back frame, respectively The shelf frame may be connected to and in the same manner as described above. In this case, the two old and new shelves at the same height are in opposite directions to each other, and the upward hooks of the shelves are in asymmetrical positions, so that they do not interfere with each other on the same horizontal bar of the back frame. Can be combined.

Further, in order to connect another assembly shelf to the opposite side of the sleeve frame of the unit assembly shelf, a back frame to be added to the existing back frame is made to adjoin by aligning the upward hooks of both back frames in the same direction, After lowering the height of the additional back frame and aligning its upward hook with the downward hook of the existing sleeve frame, push up the additional back frame to engage both hooks. Then, the sleeve frame may be coupled to the opposite side of the additional back frame, and the shelf frame may be coupled to the new and old sleeve frames and the additional back frame in the same manner as described above. The push-up of the back frame can be easily performed because it is independent of the weight of the stored items in the existing assembly shelf.

FIG. 3 is an elevational view of a back frame 1 and a sleeve frame 2 of one embodiment of the present invention shown in FIGS. 1 and 2, respectively. The back frame 1 is formed by welding a vertical bar 10 made of, for example, a steel rod of 7 mmφ and horizontal bars 11 made of a steel rod of, for example, 6 mmφ, which are slightly thinner than this, in a grid pattern, and one end of the horizontal rod 11 is welded. On the left and right sides, upward hooks 12 protruding from the outer vertical bar 10a or 10b are alternately bent and formed, and the other end is cut so as not to overlap the outer vertical bar 10b or 10a.

The sleeve frame 2 is formed by welding the vertical rods 10 and the horizontal rods 11 and the vertical rods 20 and the horizontal rods 21 of the same material, respectively, at regular intervals equal to the horizontal rods 11 in the vertical direction and at appropriate intervals in the horizontal direction in a grid pattern. The downward hook 22 protruding from the one outer vertical bar 20a is provided at one end of the horizontal bar 21, and the other outer vertical bar 20 is provided at the other end.
The upward hooks 23 in the shape of upper rounding protrusions protruding from b are respectively bent and formed.

A horizontal bar 21 is provided between the hook 12 and the vertical bar 10a or 10b.
There is enough space to put two of them side by side, and the downward hook 2
An interval substantially the same as the above interval is also provided between 2 and the vertical bar 20a. Further, a sufficient space is provided between the upward hook 23 and the vertical bar 20b so that a horizontal beam 31 of the shelf frame 3 described later can be inserted therein.

The vertical bars 10a and 10b of the back frame 1 and the vertical bars 20b of the sleeve frame 2 are threaded at their lower end projecting portions, and a tubular nut 24 is screwed into this (FIG. 3), and the height of the nut 24 is adjusted at the bottom. The central screw shaft 26 of the base 25 is screwed in to support the back frame 1 vertically and at a desired height, and after being connected to the back frame 1, the sleeve frame 2 is vertically supported.

As shown in FIGS. 4 to 6, the shelf frame 3 includes a front and rear beam 30 made of a 6 mmφ steel rod made of the same material as the back frame 1, and 7 mm in the same manner.
It is formed by welding front and rear cross beams 31a, rear cross beams 31b, and intermediate cross beams 31c and 31d made of φ steel rods in a grid shape,
The front and rear beams 30 are continuous by bending the front part of each of the two front and rear beams in a U-shape.
Each of a and 30b has a V-shaped hook 32 protruding downward from the rear cross beam 31b, bent downward, and then rising upward. The V-shaped hook 32 is provided on the front and rear beams as close to this as possible, except for the outermost front and rear beams 30c. Horizontal beams 31a, 3
1d slightly crosses the front and rear beams 30 in opposite directions, and has downward hooks 33 at both ends. Due to the oblique crossing, the hooks 33 at both ends are displaced in the front-rear direction by at least the diameter of the horizontal beam 31. In addition, horizontal beam 31
Left and right detent members 34 made of the same material as the lower side of a and 31d.
Are welded, and a gap 35 into which the horizontal bar 21 of the sleeve frame 2 is inserted is provided between the end of the welding and the inner surface of the hook 33.

Next, the method of assembling the main assembly shelf will be described. First, after adjusting the height adjustment bases 25 on both sides of the back frame 1 to make the horizontal bar 11 of the back frame 1 parallel to the floor surface, an operator supports the back frame 1 with one hand almost vertically on the floor, Hook 22 of one sleeve frame 2 with the other hand
Is hung on the hook 12 on one side of the back frame 2 and the adjusting base 25 of the sleeve frame 2 is adjusted to level the back frame 1 vertically. Next, the hooks 22 on the other sleeve frame 2 are similarly set to the hooks 1 on the other side of the back frame 1.
Similarly, the adjustment base 25 is adjusted by engaging with 2, and the whole is made into a U-shaped self-standing assembly. Since half of the weight of each sleeve frame 2 is applied to the hooks 12 of the back frame 1 in this self-supporting assembly, the back frame 1 and the sleeve frame 2 cannot be disengaged even when the self-supporting assembly is shaken in the left-right direction.

Next, the upward hooks 32 of the shelf frame 3 are hung from the bottom of the horizontal frame 11 of the back frame 1 from below to lower the front part of the shelf frame 3 and the hooks 33 of the sleeve frame 2 at the same height. When hung on the upper side, the horizontal bar 21 enters the inside gap 35 of the hook 33 and the sleeve frames 2 are coupled to both sides of the shelf frame 3.

At the time of the above-mentioned assembly, the vertical bar 20 of the sleeve frame 2 slightly inclines from the vertical due to the play due to the dimensional tolerance of the engaging portion of each hook, but this inclination decreases as the number of the shelf frames 3 increases. Even if the degree is set to a value convenient for assembly, the vertical bar 2
0 is kept substantially vertical so that no inclination can be visually observed. Since the upward hooks 32 are lower than the front and rear beams 30, the assembled shelf frame 3 tilts rearward downward to not only stably support the stored items, but also to allow the worker to take out the items from the high shelf frame 3. Even when riding on the front part of the lower shelf frame 3, the upward hook 32 engages with the lower surface of the horizontal bar 11 of the back frame 1 to prevent the shelf frame 3 from rolling upward.

In addition, the horizontal bars 11a and 21a are fixed to the uppermost portions of the back frame 1 and the sleeve frames 2, respectively, and the shelf frame 3 lacking the upward hook 32 is joined to the top frame 4 to form a unit assembly shelf. Complete the assembly.

In order to form another assembly shelf behind the unit assembly shelf, as shown in FIG. 7, downward hooks of another sleeve frame 2A are provided from the back side on the upward hooks 12 at both ends of the back frame 1 of the existing assembly shelf. 22
A is engaged, and after the engagement, the adjustment base 25 of the sleeve frame 2A is adjusted to make the sleeve frame 2A vertical, and then the shelf frame 3 and the top plate 4 are attached to the sleeve frame 2A and the back frame as described above. Just combine them.

In order to connect another assembly shelf to the opposite side of the sleeve frame 2 of the unit assembly shelf, another back frame 1A is attached to the back frame 1 and the upward hook 1 of the same height is used.
2 so that they are adjacent to each other in the same direction, and the height of the back frame 1A is adjusted by lowering each by 25, and then the upward hook 12 is aligned with the downward hook 12 of the sleeve frame 2, and then by adjusting each 25, the back frame is adjusted. 1A is pushed up and its upward hook 1
2 is engaged with the downward hook 22 of the sleeve frame 2.

Then, another sleeve frame 2 is engaged with the other side of the back frame 1A in the same manner as described above to adjust the height of the sleeve frame, and then the shelf frame 3 and the ceiling frame 3 and the ceiling frame 3 are attached to the back frame 1A and the sleeve frames 2 on both sides thereof. The plates 4 may be joined in the same manner as described above. In this case, the downward hooks 33 on both sides of the shelf frame 3
Since the front and rear positions are slightly displaced, the downward hooks 33 of the adjacent shelf frames 3 do not interfere with each other.

Instead of the lateral beams 31a, 31d, etc., two lateral beams 31e, 31e, which are orthogonal to the front and rear beams 30 as shown in FIGS.
31f, and hooks 33a facing downward at opposite ends thereof
May be formed, and this may be engaged with the horizontal bar 21 of the sleeve frame 2. In this case, the left / right detent member 34 is welded to one of the lateral beams 31e and 31f.

In the above embodiment, the horizontal bars 11 and 21 of the back frame 1 and the sleeve frame 2 are arranged at equal intervals in the vertical direction, but if the heights of the horizontal bars 11 and 21 are equal to each other, they may not be evenly spaced in the vertical direction. Good.

Effects of the Invention The present invention has the following effects by including the above configuration.

Since the back frame and the sleeve frame are connected by the engagement of the upward hook and the downward hook, the back frame and the sleeve frame can be connected by only one worker, and further, the shelf frame can be connected to this by one person. It is possible to assemble and disassemble the assembly rack of multiple people by one person because it can be connected by.
Storage costs can be significantly reduced.

In addition, the sleeve frame and shelf frame that have been once joined will not come off even if the assembly shelf is tilted to the left and right and back and forth, and if the inclination is too high, the back frame and the sleeve frame will be fastened only with a part of strings. Since it only needs to be done in advance, the number of assembling steps is extremely small.

Even if a person gets on the front of the shelf frame, the shelf frame is safe because it does not fall down,
It is possible to safely take out items stored in high places.

Since multiple assembly shelves can be added in the front-rear and left-right directions, the occupied floor area is small relative to the total storage amount, the expansion cost can be saved, and it is not necessary to protect each storage shelf as in the conventional case. , Storage cost is low.
