The frame 6 is provided.
Since the connecting structure and assembling method of the respective constituent members of the frame 6 are not directly related to the present invention, detailed description thereof will be omitted.

  The frame 6 forms a main part of the strength maintaining member in the assembly shelf, but since the lower parts of the front left and right columns 2, 2 are not connected by the front connecting member 5, the frame 6 has sufficient strength. I can't say.

The middle portions of the front and rear struts 2, 2 are also connected to each other by a plurality of side connecting members 7 that are vertically separated from each other.
The side connecting member 7 has a different shape from the side connecting member 3 that connects the upper and lower portions of the front and rear columns 2 and 2, but may have the same shape.

The side end portions of the shelf 8 are supported by the side connecting members 7, 7 that are opposed to each other on the left and right and have equal height.
In this example, the shelf board 8 has four steps, and a truck, a stocker, a storage article, etc. (all not shown) can be placed in and out below the bottom shelf board 8 along the floor surface 1 from the front. The storage space 9 is formed.

Next, with reference to FIGS. 2 to 8, the relationship between the shelf board 8, the side connecting members 7 that support the shelf board 8 and the support columns 2 will be described in detail.

The plurality of substantially inverted trapezoidal engagement holes 10 are provided at equal intervals in the vertical direction.

  Each side connecting member 7 is formed by bending a vertical base piece 7a which is long in the front-rear direction and a right angle outward from the upper end of the base piece 7a, and makes the front-rear length shorter than the front-rear length of the base piece 7a. , An outward bending piece 7b that is adapted to enter between the facing surfaces of the front and rear struts 2 and 2, and is bent and formed at a right angle inward from the lower end of the base piece 7a to support the side end portion of the shelf board 8. And the side edge of the shelf plate 8 placed on the shelf plate receiving piece 7c, which is bent inward from the front and rear ends of the base piece 7a in a plan view at a right angle. By sandwiching the part from the front and back, it comprises a short inward projecting piece 7d (rear one is not shown) which prevents the shelf plate 8 from moving in the front-rear direction with respect to the side connecting member 7.

  At the front and rear ends of the base piece 7a, two upper and lower engaging pieces 11, 11 which are adapted to be engaged with engaging holes 10 provided on the inner side surfaces of the front and rear columns 2, 2 are cut outward downward. Raised (rear ones are not shown).

A cut-and-raised piece 13 (in the rear one, an opening 12 is formed in the front and rear) by projecting outwardly in a trapezoidal shape inward of the locking pieces 11 and 11 of the base piece 7a in the front-rear direction. (Not shown) is provided.
The front end of the front cut-and-raised piece 13 is brought into contact with the rear surface of the front strut 2, and the rear end of the rear cut-and-raised piece (not shown) is brought into contact with the front surface of the rear strut 2. It is intended to prevent the stanchions 2, 2 from moving inward relative to each other.
Further, the rear opening 12 of the front cut-and-raised piece 13 forms an engaged portion for inserting and engaging an engaging piece 18 of a coupling fitting 16 described later from the rear side.

  Suspension holes 14 and 15 for suspending and supporting the side connecting member 7 at the time of coating are provided at the front and rear ends of the outward bending piece 7b of the side connecting member 7 and the front and rear ends of the shelf receiving piece 7c. It is provided (the rear one is not shown).

  In each side connecting member 7, the front end of the front cut-and-raised piece 13 is in contact with the rear surface of the front pillar 2, and the rear end of the rear cut-and-raised piece (not shown) is in contact with the front surface of the rear pillar 2. In this way, the outward bending piece 7b is inserted between the front and rear struts 2 and 2 so that the front and rear ends of the base piece 7a are brought into contact with the inner side surfaces of the front and rear struts 2 and 2. Two locking pieces 11, 11 provided at the front and rear ends of 7a are fitted into engagement holes 10, 10 provided on the inner side surfaces of the front and rear columns 2, 2 and having the same height. By being lowered to and locked at its lower edge, it is firmly locked to the front and rear columns 2, 2.

Each shelf 8 has a horizontal top plate 8a, side pieces 8b hanging from the left and right side ends thereof, a hanging piece 8c hanging from the front end of the upper surface plate 8a, and a folding piece 8d facing rearward from its lower end. It has a short standing piece 8e standing upright from the rear end.
At the rear end of the top plate 8a, there are provided a hanging piece, a folding piece and a standing piece which are symmetrical with the hanging piece 8c, the folding piece 8d and the standing piece 8e at the front end, which are directly related to the present invention. Therefore, illustration and detailed description are omitted.

  The left and right ends of each shelf 8 are sandwiched between the front and rear inward projecting pieces 7d, 7d of the left and right side connecting members 7, 7 that are at the same height, and are placed on the shelf receiving piece 7c. By being placed, it is stably supported in the frame 6.

  Simply placing the left and right ends of the shelf plate 8 on the shelf plate receiving pieces 7c of the left and right side connecting members 7, does not make the shelf plate 8 a strength maintaining member of the assembly shelf. It is only a member supported by the frame 6.

  Therefore, in this embodiment, the lowermost shelf plate 8 and the left and right side connecting members 7 supporting the shelf plate 8 are connected by the connecting fittings 16 serving as a restraining means to prevent the leftward and rightward movements thereof. Thus, the lowermost shelf 8 is used as a part of the strength maintaining member located at the intermediate portion in the vertical direction of the frame 6, and thus the storage space 9 is formed below the lowermost shelf 8. The lower ends of the front left and right columns 2, 2 are prevented from expanding, and all columns 2 are prevented from swinging in the left-right direction, so that the strength of the entire assembly shelf can be increased. .

  The connecting metal fitting 16 passes through the side piece 16a facing the outer side surface of the side connecting member 7 in the vertical direction and the lower end of the side piece 16a and below the shelf board receiving piece 7c of the side connecting member 7. The bottom piece 16b facing inward, the standing piece 16c standing inside the shelf receiving piece 7c from the inner end of the bottom piece 16b, and the horizontal fixing piece 16d connected to the upper end of the standing piece 16c. Has become.

  By providing a rectangular notch 17 that is recessed rearward at the vertical middle portion of the front edge of the side piece 16a, the front upper portion of the side piece 16a is the engaged portion of the side connecting member 7. An engaging piece 18 that faces the front is formed so as to be inserted into the opening 12 at the rear of the cut-and-raised piece 13 from the rear side so as to be engaged.

The bottom piece 16b has a trapezoidal shape in plan view such that the front edge thereof protrudes forward as it goes inward from the lower end of the side piece 16a, and the standing piece 16c standing from the inner end thereof has the engagement piece 18 on the side part. When it is inserted into the opening 12 of the connecting member 7 from the rear side and engaged therewith, the shelf connecting member 7c of the side connecting member 7 is inclined outwardly and upwardly so as to overhang above the upper surface of the shelf receiving member 7c. is there.
In this way, when the upright pieces 16c are inclined outward and upward, the side pieces 16a of the fitting 16 contact the outer surface of the side connecting member 7, and the upright pieces 16c inclined outward are connected to the side portions. By engaging the shelf receiving piece 7c of the material 7, the coupling fitting 16 can be locked to the lower portion of the side connecting material 7, which facilitates the assembly work.
The standing piece 16c may be vertical.

  The fixed piece 16d has a lateral width that increases toward the front, and the front end portion that protrudes forward from the upright piece 16c has a rectangular shape in a plan view, and a screw insertion hole 19 that faces the up and down direction is provided in the center thereof, and is located above it. The square nut 20 having the screw hole 20a aligned with the screw insertion hole 19 is fixed to the upper surface of the fixing piece 16d by welding.

  The distance from the upper surface of the bottom piece 16b to the lower surface of the fixed piece 16d in the coupling fitting 16 is determined by the thickness of the shelf plate receiving piece 7c in the side connecting member 7 and the lower surface of the folded piece 8d in the shelf plate 8 to the upper end of the standing piece 8e. It is almost equal to the sum of the distances.

Next, how to attach the coupling fitting 16 will be described.
