Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rack suitable for storing relatively lightweight and small loads.

Conventional racks of this kind have been constructed by using square pipes for the front and rear columns, and by abutting and fixing the rising plate portions of load receiving plates made of angle material to the sides of the front and rear columns. In such a conventional configuration, the guide surface for guiding the load to the load storage space between the left and right columns has the rising plate portion of the load receiving plate extending forward from the columns and tilting outward from the left and right. This not only complicates the structure, but also increases the overall cost as there is a risk of deformation due to contact with the load if sufficient strength is not provided to protrude to the front of the column. There was a drawback. Also, when attaching the rising plate part of the load receiving plate to the side of the support column, consideration must be given to prevent the bolt heads etc. from protruding to the side surface, and screw holes must be machined on the side of the support support. Therefore, there is a risk that the strength of the pillar will decrease.

The present invention proposes a solution to the conventional problems mentioned above, and its features are as follows:
It is equipped with front and rear pillars and a load receiving plate installed between the front and rear pillars, and each of the pillars has a storage guide surface that tapers in the front half of both left and right sides, and a loading guide surface that tapers from the center of the rear side. A load receiving plate mounting protrusion projecting rearward and having a width smaller than the column width is integrally formed over the entire length, and this support is erected in the front and back such that the protrusions face each other, and the load receiving plate is It is constructed from an angle material having a rising plate part, and a pair of left and right load receiving plates are arranged so that the front and rear ends of the rising plate part sandwich the protrusions of both the front and rear columns from both sides, and the protrusions and the protrusions on both sides thereof are The point is that the rising plate part is fastened with a common bolt and nut.

Hereinafter, one embodiment of the present invention will be explained based on the attached illustrative drawings. In Figs. 1 and 2, 1 is a rack erected across a traveling path 2 for loading/unloading cranes, etc. be. Each of these racks 1 has a front row of columns 3a erected at required intervals in the left and right lateral directions.
It has a rear column column 3b which is similarly erected, and a load receiving plate 4 which is installed between the corresponding columns 3a and 3b in the front and rear.

As shown in FIGS. 3 to 5, each of the pillars 3
The columns a and 3b are manufactured by aluminum extrusion molding and have the same cross-sectional shape, and are arranged in opposite directions, and each of the columns 3a and 3b is located at the front half of the left and right side surfaces 5. A warehousing guide surface 6 that tapers toward the tip, and a load receiving plate mounting protrusion 8 that is narrower than the column width and that protrudes rearward from the center of the rear end surface 7 are integrally formed over the entire length, and A through hole 9 penetrating the entire length at approximately the center position
was formed. 10 is a recessed groove formed over the entire length at the center position of the front end surface;
Together with the through hole 9, this helps to reduce material and weight.

The load receiving plate 4 is formed from an angle material, and the fixing bolt nut 11 is held in a state in which both the front and rear ends of the rising plate portion 4a are abutted against the side surfaces of the mutually opposing protrusions 8 of the pillars 3a, 3b, which are oriented in opposite directions.
It is fixed to the protrusion 8 by. The bolts and nuts 11 that fix this load receiving plate 4 are
It does not protrude outward from the imaginary plane connecting the left and right side surfaces 5 of b. In addition, at locations other than both ends of the rack 1 in the longitudinal direction, the load receiving plates 4 disposed on both left and right sides of the support columns 3a and 3b are fastened and fixed together by a common bolt nut 11. Reference numeral 12 denotes a warehousing guide plate portion that projects obliquely downward from the front end of the cargo receiving plate 4. Reference numeral 13 is a load sliding material attached to the load support portion of the load receiving plate 4 as necessary, and is used to improve the sliding of the load on the load receiving plate 4 during loading and unloading.

Reference numeral 14 denotes a load stopper, which is made of an elastic material such as rubber and is attached to both ends of a mounting plate 15 that is screwed to the rearward front end face of the rear support column 3b and protrudes on both left and right sides. Of course, at both longitudinal ends of the rack 1, the mounting plate 15 projects only to one side, and one load stopper 14 is attached. Instead of the load stopper 14, a load stopper formed by bending the rear end of the load receiving plate 4 and integrating the load stopper 14 can also be used.

A load 16 such as a case of a predetermined size is carried by four supports 3 as shown by imaginary lines in FIGS. 1 and 2, respectively.
In the load storage space surrounded by a to 3b, the left and right sides of the bottom of the load 16 are supported by a pair of left and right load receiving plates 4, and the left and right sides of the rear end are supported by a pair of left and right load stoppers 14. Although the cargo 16 is stored in contact with the cargo, when the cargo 16 is stored, the rear end of the cargo 16 swings to the left or right and collides with the forward facing rear end surface 7 of the rear support 3b or the bolt/nut 11. We must ensure that there are no For this reason, if necessary, a load side guide member 17 made of a material that slides easily against the load and having approximately the same width as the support columns 3a and 3b may be integrally installed from the lower central portion as shown by the imaginary line in FIG. It can be constructed between the front and rear pillars 3a and 3b by an appropriate method such as fitting and fixing a fitting part 17a protruding from the front and rear pillars 3a and 3b between the rising plate parts 4a of the left and right pair of load receiving plates 4. Also, instead of using the load side guide member 17 as described above, the load side guide rising plate part 18 can be integrally folded from the upper end of the rising plate part 4a of the load receiving plate 4 as shown in the left half of FIG. They can be arranged in a continuous manner, or a load side guide member 19 fixed to the outer surface of the rising plate portion 4a of the load receiving plate 4 can be used as shown in the right half of FIG. The load side guide member 19 can also be tightened together using the load receiving plate fixing bolts and nuts 11.

FIG. 7 shows that when the protrusions 8 of the supports 3a and 3b are made wide and the load receiving plate 4 is attached to the protrusions 8 via the rising plate part 4a, the outer surface of the rising plate part 4a and the support An example is shown in which the left and right side surfaces 5 of 3a and 3b are substantially flush with each other.
In this case, there is no need to use the special load side guide member as described above, but the load receiving plate 4 is
Care must be taken to ensure that the bolts and nuts fixed to the plate do not protrude from the rising plate portion 4a.

According to the ease of the present invention that can be implemented as described above, the storage guide surface for guiding the cargo to the cargo storage space between the columns is integrally molded on both sides of the column itself,
Compared to the conventional structure in which a part of the load-receiving plate extends forward from the support column, the structure of the load-receiving plate is not only simpler, but also less susceptible to deformation due to contact with the load. There is no such thing as a rug, so it can be used as a durable rack. Furthermore, since the distance between the front and rear columns can be maximized compared to the conventional structure, the stability of the rack as a whole is improved.

Furthermore, since the support is integrally formed with a protrusion for attaching a load receiving plate, it is no longer necessary to attach the load receiving plate to the side of the support as in the past. Since the rising plate portions of the plates are pressed against each other and fastened with common bolts and nuts, not only is it possible to eliminate the need to reduce the strength of the columns by creating screw holes in the columns, but also the strength of the columns can be increased by integrally molding the protrusions. can be significantly improved. Furthermore, the load receiving plate can be attached extremely easily.

In other words, if the cargo receiving plate mounting structure that provides such advantages is adopted, it is no longer possible to extend the rising plate portion of the cargo receiving plate forward to form a warehousing guide surface as in the conventional method. In view of this point, the present invention has the storage guide surface integrally formed on the support column itself, and as a result, the above-mentioned effects can also be obtained.

The through hole 9 can be formed by forming screw grooves on the inner surfaces of both its upper and lower ends, so that the base material 20 for fixing the lower end of the column and the beam material for fixing the upper end of the column (not shown) shown in FIGS. 1 and 2 can be formed. Both the upper and lower ends of the through-hole 9 can be used as screw holes when screwing the support column to, etc.
