Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column and a horizontal member for constructing a rack.

[0002]

2. Description of the Related Art A rack constructed by combining a column having a plurality of hook receiving holes in the height direction and a horizontal member such as a crosspiece or a shelf having hook members at both ends in the longitudinal direction is well known. Is. This kind of rack is
It is convenient because it can be set at any height (shelf) and can be assembled without using bolts and nuts.

[0003]

There are some racks of this type that are struck by horizontal members between the columns, which causes rattling of the horizontal members. From the standpoint of increasing the strength (loading weight), there has been a demand for eliminating this rattling. However, there has not yet been developed a material which satisfies the above requirements without causing structural complication and having the ease of assembly.

The present invention has been made in view of the above circumstances, and completely prevents rattling in the erected state of a horizontal member while preventing structural complication and maintaining ease of assembly. It is an object of the present invention to provide a rack assembly column and a horizontal member that can be prevented and can satisfy the above requirements.

[0005]

In order to achieve the above object, the present invention takes the following technical means. That is, the support column according to the present invention is a support column capable of engaging with the hook portion of the horizontal member in the support column that constitutes a rack in combination with the horizontal member having hook portions orthogonal to the longitudinal direction projecting from both ends in the longitudinal direction. A mouth portion is provided, and each support mouth portion has an opening shape in which the upper side is wide and the lower side is narrower,
It is characterized in that bent ribs are provided along the left and right opening edges on the hook portion of the horizontal member so as to be capable of abutting from the left and right.

In the support opening, the opening edge and the bending rib near the side on which the horizontal member is arranged are formed to be inclined or rounded in the direction of pulling the horizontal member to the column side, and the other opening edge and the folding rib. The curved ribs are preferably formed vertically. Further, the horizontal member according to the present invention is provided, at both longitudinal ends thereof, with a vertically long joint fitting capable of contacting at least a vertical surface provided with a support opening portion of the strut according to the present invention, It is characterized in that a hook portion engageable with the above-mentioned bearing portion is projectingly provided on these joint tools.

[0007]

In the rack constructed by combining the support column and the horizontal member according to the present invention, the left and right bending ribs provided at the supporting port of the support column contact the left and right sides of the hook portion of the horizontal member with the surface pair. This is pressed against each other. Since the support port portion is narrower toward the lower side, the above contact degree (opposing pressing force) increases as the hook portion is pushed downward. That is, the hook portion is positioned in the left-right direction (longitudinal direction of the horizontal member) in a state where there is no play, and the positioning state is oriented in the left-right direction on the material of the hook portion and the bending rib or the structure. It will be urged by the elastic force.

If the opening edge and the bending rib near the side on which the horizontal member is arranged are formed in a slanted or rounded shape at the bearing opening, the horizontal member is supported by engaging the hook portion of the horizontal member with this. You will be drawn to the side.

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a column, and 2 is a horizontal member (a crosspiece in this embodiment). In the following description, for convenience,
In the illustrated column 1, a vertical surface parallel to the longitudinal direction of the horizontal member 2 is referred to as a front surface 1a, and a vertical surface orthogonally adjacent to the vertical surface is referred to as a side surface 1b. At both ends of the horizontal member 2 in the longitudinal direction,
A vertically long joint fitting 3 is fixed by welding or the like. These fittings 3 are L-shaped in cross section so that they can come into contact with the right half or left half of the front surface 1a of the column 1 and the one side surface 1b adjacent thereto, and each of these fittings 3 A plurality of hook portions 5 are provided on the left or right tip edge of the horizontal member 2 in the vertical direction, the hook portions 5 being orthogonal to the longitudinal direction of the horizontal member 2 and facing the column 1.

A square pipe is used for the pillar 1, and a plurality of bearing openings 4 are formed on the front surface 1a of the pillar 1 so that the hooks 5 of the horizontal member 2 can be engaged with the internal cavity. The openings are formed at a predetermined pitch along the direction. As shown in FIG. 2, each bearing opening 4 has an opening shape in which the upper side is wide and the lower side is narrower. The opening width of the lower end portion is slightly smaller than the wall thickness of the hook portion 5 so that the hook portion 5 can be fitted forcefully. Of course, the vertical dimension of the bearing opening 4 is larger than the vertical dimension of the hook 5. An opening edge near each side of the horizontal members 2 in each bearing opening 4, that is, a right opening edge of the bearing opening 4 arranged on the right side of the column front surface 1a, a left edge of the bearing opening 4 arranged on the left side. The opening edge portion is formed into a radius (or may be a linear inclination) that gently swells toward the left-right center of the column front face 1a, and the other opening edge portion, that is, the left and right adjacent bearings. The opening edges on the sides of the mouth 4 that are close to each other are formed to be vertical. Therefore, when the hook portion 5 of the horizontal member 2 is engaged with the support port portion 4, the horizontal member 2 comes to be pulled toward the column 1.

As shown in FIG. 3, each of the support ports 4 is provided with a bending rib 6 projecting from the left and right opening edges toward the internal cavity of the column 1. These bending ribs 6 are formed by burring,
The entire height of each of the left and right opening edges and the upper opening edge are arranged in series (see FIG. 2). The vertical pitch of each hook portion 5 (three hooks in this embodiment) provided on the joint 3 of the horizontal member 2 is the same as the vertical pitch of the bearing opening portion 4, and their engagement and disengagement are not performed. Done together. In addition, when these hook portions 5 are engaged with the support opening portion 4 of the support column 1, a horizontal member is provided along the radius provided on one opening edge portion of the support opening portion 4 and the bending rib 6. Two
It is preferable that the whole is gently bent so that the pulling of the sheet can be smoothly performed (see FIG. 2).

On the front surface 1a of the support column 1, through holes 8 having an oval shape in the vertical direction are formed between the upper and lower sides of the support port portion 4, and the hook member 5 is provided on the joint tool 3 of the horizontal member 2. A through hole 9 having an oval shape in the left-right direction is formed between each of the upper and lower sides. These through holes 8 and 9 are for fitting the L-shaped safety pin 10 which holds the engagement state between the hook portion 5 and the support opening portion 4.

In order to construct a rack by combining the support columns 1 and the horizontal members 2, the support columns 1 are erected at predetermined intervals in the front-rear and left-right directions, and the support columns 1 adjacent to each other on the left and right are
The hook portions 5 (three left and right, respectively) on both ends of the horizontal member 2 lifted to a desired height are fitted into the bearing ports 4 on the side close to each other, and the horizontal member 2 is pressed downward. . As a result, the bent ribs 6 of the bearing portions 4 come into contact with and press the left and right surfaces of the hook portions 5, respectively. Moreover, since the hook 5 and the bending rib 6 are held in contact with each other by the elastic force generated on the material or on the structure, the horizontal member 2 is not rattled.

In the present invention, it is possible to use various shaped steels as the support column 1, and it is also possible to provide a plurality of vertical planes on which the support ports 4 are provided. It is also possible to use a shelf plate as the horizontal member 2, and in this case, the front and rear joint fittings 3 may be provided at both left and right ends of the horizontal member 2. The number of protrusions of the hook portion 5, the detailed shape, and the like can be arbitrarily changed.

[0015]

According to the present invention, which has the above-described structure, the support opening portion provided on the support column is narrowed toward the lower side, and the left and right opening edges of the support opening portion are provided on both the left and right sides of the hook portion of the horizontal member. Since the bent rib that abuts against the hook is provided, the hook portion does not play in the left-right direction (longitudinal direction of the horizontal member), and therefore the rattling of the horizontal member does not occur. Therefore, the stability of the placement of the article can be achieved, noise is not generated, and the strength of the rack can be improved (the weight of the placed product can be increased). Of course, there is no structural complication, and the convenience of easy assembly remains.

If the support member has an opening shape that allows the horizontal member to be pulled toward the support by engaging the hook member of the horizontal member, the erected state of the horizontal member can be further stabilized.
