The present invention relates to a connection structure of two supports that cross each other having a convenient structure and a strong connection.

Shelves (or racks) are installed in a predetermined place in order to increase space efficiency, and are means for placing various items on a floor. Such a shelf may be used as a decorative cabinet in a home, used to place an aquarium or a flower pot in a living room or a balcony, or may be used to display a plurality of products in a store.

Conventionally, an angle called a means of placing a heavy object was widely used, which is not preferred at home because corrosion occurs and the appearance is not good and assembly is not easy. Therefore, custom-made aluminum shelves have been used in accordance with the specifications to meet the needs of consumers. These shelves were to be manufactured in advance in the workshop equipped with professional production equipment and then moved to the installation site. In particular, lathes that require a strong structure cannot have the desired structural rigidity by bolt assembly alone, and therefore, two supports (particularly a vertical support and a bar in FIG. 1) have to be assembled by welding. However, when the size of the shelf became large, it was inconvenient or impossible to install the welded finished product in a narrow installation place. Therefore, the shelf could not be integrated and had to be separated into several pieces. This has disadvantages in space efficiency, aesthetics and installation cost.

On the other hand, the above disadvantage is not only a problem of the silk shelf, but also a chronic problem occurring in the connection structure of the two supports that cross each other such as signs.

In addition, a snap groove 120 is formed on each circumferential surface except for the surface on which the dovetail part 110 is formed, so that the sub support 400 can be installed. Referring to FIG. 1, the sub support 400 is the snap groove. It is inserted into the 120 has a form of the handrail connected between the vertical support 100 and the vertical support (100).

In addition, if necessary, the bottom of the vertical support 100 may be provided with a known leg 130 (see FIG. 1) or a wheel, and an upper cap 140 may be covered on the top.

The horizontal support 200 is fixed by being vertically displaced (變 位) along the vertical support 100 by the fastening means 300, and includes a socket portion 220 which is fitted to the vertical support 100 Is done. The horizontal support 200 may also be manufactured by drawing or extruding aluminum or alloys thereof.

The socket portion 220 has a single tube shape, and the outer surface thereof is coupled to be integral with the end of the horizontal support 200 by welding or the like, and the dovetail portion 110 and the male and female of the vertical support 100 on the inner surface thereof. It has the corresponding dovetail part 221 couple | bonded, and has a cross-sectional shape fitted closely to the exterior of the vertical support 100. As shown in FIG.

The socket 220 may slide freely along the extension direction of the vertical support 100 in a state in which it is fitted to the vertical support 100, whereby the user may have the horizontal support 200 at a desired height. ) Can be installed.

Meanwhile, according to FIG. 1, four vertical supports 100 are arranged in a rectangular shape, and a shelf in which horizontal supports 200 are installed between the vertical supports 100 is illustrated. In this case, the horizontal support 200 is the socket portion 220, the cross section 230 connected between the socket portion 220, and the support panel 210 is fixed horizontally to the cross section 230 It is made to include.

In this case, the support panel 210 is for mounting an object, and may be fixed by various methods such as integrally manufactured by welding or a fitting type by an uneven groove or an assembly type by a bolt.

Also, according to FIG. 2, a sign in which two horizontal supports 200 are installed in one vertical support 100 is illustrated. In this case, the horizontal support 200 is the socket portion 220, the cross section (230 ') connected to the socket portion 220, and the guide panel 240 is fixed perpendicular to the cross section (230') It is made, including.

It can be fixed by various methods, such as using a clamping means of.

As such, the connection structure of the present invention can be applied to various fields within the range in which the two supports intersect.

Hereinafter, the fastening means 300 for achieving the connection structure of the present invention will be described.

The fastening means 300 includes a bolt hole 310, a bolt 320 fastened thereto, and a deformation protrusion 330.

The bolt hole 310 is formed in the socket portion 220 and passes through the corresponding dovetail portion 221 toward the vertical support 100.

The bolt hole 310 may be provided in two or more in a line along the longitudinal direction of the socket portion 220, ribs (lib, 222) for securing the fastening force is formed in the portion where the bolt hole 310 is provided It is twice as thick as other parts.

The deformation protrusion 330 is formed in the dovetail portion 110 so that the end portion 321 of the bolt 320 can be dent while being crushed by the bolt 320 fastened through the bolt hole 310. That is, the deformation protrusion 330 is deformed by the end portion 321 of the bolt 320, thereby inducing the dovetail portion 110 and the corresponding dovetail portion 221 to be in close contact with each other.

The deformation protrusion 330 is preferably to be formed integrally at the time of drawing or extrusion of the vertical support 100, whereby it is provided in the entire section along the length of the vertical support (100). In addition, a portion 160 (see FIG. 3) in which the deformation protrusions 330 are formed is thicker than other portions for strength reinforcement.

The bolt 320 preferably uses a fastening element called a tannery bolt or a tannery wrench bolt to impart a large fastening force, but it is of course not limited thereto. The number or fastening positions of the bolts 320 may also be changed in various ways as necessary. However, according to the present embodiment, the bolt hole 310 and the deformation protrusion 330 are formed toward the front of the shelf so as to fasten the bolt 320 at the front of the shelf.

4 to 5, it can be seen that the end portion 321 of the bolt 320 is coupled while twisting the deformation protrusion 330 and is coupled with the vertical support 100 as if it is a wedge. In particular, even if a large load is applied from the top in the state of FIG. 5, the socket part 220 may not slide downward along the vertical support 100. This means that the connection structure of the present invention can greatly improve the strength against load. Nevertheless, it does not damage the basic shape of the vertical support 100 and does not weaken the rigidity of the vertical support 100. In addition, the original restoring force of the deformation protrusion 330 prevents the bolt 320 from being easily relaxed, so that the bolt 320 receives a similar action to the locking bolt or the spring washer.

The above-described bolt hole 310 and bolt 320, and the deformation protrusion 330 will be determined in detail in each part in consideration of the fastening force and the required supporting load of the bolt 320. Prerequisite is that the fastening force of the bolt 320 must exceed the yield strength of the deformation protrusion 330.

On the other hand, as shown in Figure 6, the intermediate plate 150 may be further provided inside the vertical support (100). The intermediate plate 150 is formed across the center of the vertical support 100 so as to correspond to the direction in which the bolt 320 enters, and is applied to the vertical support 100 by pressing the bolt 320. It can improve the strength against losing force.
