FIG. 7 is a perspective view of an essential part showing another embodiment of a stopper for a beam unit according to the present invention.

In FIG. 1, reference numeral 1 denotes a shelf, which is formed by assembling components such as a side unit 2, a shelf unit 10, and a beam unit 15, has four upper and lower housings, and is arbitrarily arranged in the horizontal direction. It can be expanded. Each storage unit houses a case 20 such as a cardboard box for storing parts or products.

The side unit 2 is as shown in FIG. That is, a diameter of about 10 mm and a length of about 2190 mm
Nine vertical rods 3 made of metal round bars are arranged upright at an interval of about 170 mm in the front-rear direction (the left-right direction in FIG. 2), and the left and right sides of the upper and lower five places of each vertical rod 3 are arranged in the front-rear direction. A pair of lateral rods 4 extending and facing each other are fixed by welding, thereby forming a lattice-shaped side unit 2 having a height of about 2190 mm and a front and rear width of about 1380 mm. The horizontal rod 4 has a thickness of about 7 mm in the left-right direction, a width of about 10 mm in the vertical direction, and a length of about 13 in the front and rear.
It consists of a 65 mm metal flat plate,
It is fixed to the left and right surfaces of each of the vertical rods 3 at an interval of 0 mm.

[0008] One of the lower horizontal rods 4a of the horizontal rod 4
Is an L-shaped steel, and its lower side 4a-1 is located on the lower surface of each vertical rod 3 so as to have the function of a leg. Further, of the vertical rods 3, a metal engaging body 5 (5
a to 5d) are fixed by welding. The engaging body 5 is adapted to be engaged with and engaged with engaging pieces 16a and 16b of a beam unit 15 to be described later, and has an outer diameter of about 13.8 mm, an inner diameter of about 9.2 mm,
The longitudinal rod 3a is made of a steel pipe having a length of about 20 mm. 8 are fixed.

The above-mentioned shelf unit 10 is as shown in FIG. That is, two width rods 11 made of a metal round bar having a diameter of about 8 mm are arranged in parallel in the front-rear direction at an interval of about 490 mm, and six connecting rods 1 are provided between each width rod 11.
2 are arranged at predetermined intervals on the left and right, and they are fixed to each other by welding. In addition, each of the width bars 11
The left and right ends are bent downward to form engagement pieces 11a and 11b, and a diameter of about 10 mm is formed on the lower surface of the straight portion of each width rod 11.
The reinforcing rod 13 of mm is fixed by welding to increase the bending rigidity. This makes the left and right width about 1025 mm, the front and rear width about 49
A shelf unit 10 having a rectangular shape in a plan view and having a length of 0 mm is formed.

The beam unit 15 described above is configured as shown in FIG. That is, two locking rods 16 made of a metal round bar having a diameter of about 8 mm are vertically moved by about 980 m.
m, and two connecting rods 17 bent in a V shape are arranged back to back between the locking rods 16,
Both ends of each connecting rod 17 are fixed to each locking rod 16 by welding, and the back portions 17a of each connecting rod 17 are fixed to each other by welding. The left and right ends of each locking rod 16 are bent downward to form engagement pieces 16a and 16b. As a result, the front view X becomes about 1025 mm in width from side to side and 980 mm in width from top to bottom.
A beam unit 15 having a shape is formed. The length of the engagement pieces 16a and 16b of each of the locking rods 16 is a length protruding downward from the engagement body 5 of the side surface unit 2. Further, a stopper 18 (FIG. 6) capable of being press-fitted is provided at the lower end of the engagement body 5. The stopper 18 is made of a hard plastic pipe.

The retaining member 18 may be a metal washer having a large number of engaging pieces circumferentially divided on an inner peripheral portion thereof. As shown in FIG. 7, a pair of plate-shaped stoppers 18 a and 18 a and small screws 18 b and 18 b for tightening the plate-like stoppers 18 a and 18 b are formed. The stoppers 18a, 18a are extended in the front-rear direction and fastened and fixed to the vertical rod 3a located immediately above the mating pieces 16a, 16b.
The engagement piece 1 of the beam unit 15 fitted to the front and rear engagement bodies 5
The upward movement (disengagement) of 6a, 16b is prevented.

Next, the manner of assembling the side unit 2, the shelf unit 10, and the beam unit 15 will be described with reference to FIGS. First, the two side units 2, 2 are erected at predetermined intervals in the left-right direction, and the two beam units 15, 15 are vertically arranged and interposed therebetween, and the upper side beam unit 15 is interposed therebetween. , 15
The engaging pieces 16a, 16b at the left and right ends of the side units 2 and 2 are connected to the upper engaging bodies 5a, 5a (or the engaging bodies 5).
b, 5b), the engaging pieces 16a, 16b at the left and right ends of the lower beam units 15, 15 are connected to the lower engaging members 5c, 5c (or the engaging members 5d, 5d) of the side units 2, 2. The engagement pieces 16a, 16b of the beam units 15, 15 which are fitted and project downward from the engagement bodies 5a, 5a, 5c, 5c.
The stopper 18 is press-fitted into the lower end portion of FIG.

Next, 8 between each of the side units 2
The shelf pieces 10 are interposed, and the engagement pieces 11a and 11b at the left and right ends of each shelf unit 10 are
2 are successively fitted into upper and lower predetermined gaps (a) formed between the facing horizontal rods 4, 4, whereby, between the two side units 2, four on the front side, 4 on the rear side,
A total of eight accommodation rooms are formed. When it is desired to increase the number of the accommodation rooms (the number of shelves), the side units 2, 2
New side unit 2 'on left or right (not shown)
Are erected in the left and right direction, and a new beam unit 15 ′ and a shelf unit 10 ′ are interposed between the side unit 2 ′ and the side unit 2 in the same manner as described above.

In this case, the engagement pieces 16a 'and 16b' of the new beam unit 15 'are replaced with the engagement members 5a and 5
a, 5c, 5c, engaging bodies 5b, 5b,
5d, 5d. Further, the engaging members 11a 'and 11b' of the new shelf unit 10 'are fitted in the gap (a) by being shifted in the front-rear direction with the engaging pieces 11a and 11b at the left and right ends of the shelf unit 10 described above. Let it.

The dimensions of each of the side units 2, the shelf unit 10 and the beam unit 15 are appropriately set according to the size and weight of the case 20 to be accommodated. Further, the horizontal rod 4 of the side unit 2 may be a round rod material. Further, the engagement members 5 of the side unit 2 may be fixed to the left and right surfaces of the vertical rod 3a. In this case, the space in the left-right direction is slightly increased by the horizontal rod 4 and the engagement body 5 when the extension is performed. Also, the side unit 2 described above,
The shelf unit 10 and the beam unit 15 may be formed of a pipe material or a square material.

[0016]

As is apparent from the above description, the present invention forms a planar side unit, a shelf unit, and a beam unit by welding a straight rod.
An engaging gap is provided by the lateral rod of the side unit, and an annular engaging body is provided on a predetermined vertical rod of the side unit. The ends of the shelf unit and the beam unit are bent to fit the gap and the engaging body. Since it is stopped, it is inexpensive and easy to assemble. In addition, since the horizontal rod is formed of a band-shaped flat plate, and the engaging members are provided on the front and rear surfaces of the vertical rod, the space in the left-right direction, that is, the space in the extension direction is reduced at the time of extension. And so on.
