FIG. 7 is a cross-sectional view showing the coupling of the lower posts and the shock absorbing structure.

4 to 7, a loading rack 100 having a shock absorbing function according to the present invention includes a loading rack 110 having at least one post made up of a conventional lower post 110 and an upper post 120, ); A base plate (130) fixed to the floor; An upper post bracket 150 coupled to a lower end of the upper post 120 and fixed to the upper post 120 through a fastener 200; A first support bracket 140 fixed to the base plate 130 and having shock absorbing grooves 100b formed on both sides thereof; A second support bracket 160 fixed to the lower end of the upper post bracket 150 and having shock absorbing grooves 100b formed on both sides thereof; And a lower post bracket 170 having the shock absorbing grooves 100b corresponding to the shock absorbing grooves 100b while connecting the first and second support brackets 140 and 160 The lower posts 110 are fixedly coupled by the fasteners 200 penetrating the shock absorbing grooves 100b of the lower post bracket 170 and the first and second support brackets 140 and 150 So that the impact can be absorbed while being pushed backward by the clearance of the shock absorbing grooves 100b from the impact applied from the front.

The upper and lower posts 110 and 120 applied to the present invention are formed with a plurality of coupling grooves 100a through which the coupling holes 200 pass through on both sides while maintaining a substantially '

Likewise, the upper post bracket 150 and the lower post bracket 170 maintain a 'C' -shaped section while maintaining a corresponding width to be inserted into the upper and lower posts 110 and 120. Brackets 101 for braces connected to the upper post bracket 150 and the lower post bracket 170 are connected to the rear posts (not shown) and the braces, respectively.

Also, the first and second support brackets 140 and 160 maintain a width of 'C' as shown in FIG. 1, so that they can be inserted into the lower post bracket 170.

At this time, the upper post bracket 150 is formed with a coupling groove 100a at a position corresponding to the coupling groove 100a of the upper post 120 in a state where the upper post 120 is inserted.

The bracket 170 and the first and second support brackets 140 and 160 are formed with shock absorbing grooves 100b at positions corresponding to the coupling grooves 100a of the lower posts 110. [

In other words, the shock absorbing grooves 100b are formed so as to have lengths in the front-rear direction of the loading rack so as to be movable in the fore-and-aft direction of the loading rack of the fastener 200 in the shock absorbing grooves 100b .

The fastener 200 passing through the lower post 110 is fixedly inserted through the lower post bracket 170 and the shock absorbing grooves 100b formed in the first and second support brackets 140 and 160, When a shock is applied to the front surface of the lower post 110 from a forklift or a forklift in a fixed state, the fastener 200 fixed through the lower post 110 is inserted into the shock absorbing grooves 100b, The lower posts 110 are also pushed backward by the forward and backward clearances of the shock absorbing grooves 100b to absorb the shocks.

The first and second support brackets 140 and 160 coupled with the upper and lower ends of the lower post 110 and the lower post bracket 170 are provided with a bush member 105 ).

The bush member 105 provided on the first and second support brackets 140 and 160 is connected to the shock absorbing grooves 100b formed on both side surfaces of the support brackets 140 and 160, And has a hemispherical support portion 1050 and a connection portion 1051 connecting the hemispherical support portion 1050 so as to support a front outer circumferential surface of the penetrating fastener 200.

The plate-like bushing member 105 allows the fastener 200 to move in the back-and-forth direction within the shock-absorbing grooves 100b through the semi-spherical support portion 105 with one rear side opened, 200 so as to stably support the fastener 200 as a whole with respect to the longitudinal direction.

In addition, since the bush member 105 connects the shock absorbing grooves 100b formed on both sides of the first and second support brackets 140 and 160 having the U-shaped cross-sectional structure, the loading load of the loading rack, It is possible to reinforce the damages such as the distortion of the grooves 100b due to the load transmitted from the fastener 200 in the event of an impact applied in front of the fastener 200. [

As a result, the plate bushing member 105 can increase the loading load of the loading rack, which is separated into the upper and lower posts 110 and 120. In particular, an external impact is generated in the lower post 110, Even when the lower posts 110 are pushed rearward by the clearance of the shock absorbing grooves 100b and the upper and lower posts 110 and 120 are prevented from being disposed on a vertical line, 200 can be firmly supported by the outer peripheral surfaces of the upper and lower posts 110 and 120, thereby preventing damage to the upper and lower posts 110 and 120 where the load is concentrated.

An external impact is generated in the lower post 110 to cause the lower posts 110 to be pushed rearward by the clearance of the shock absorbing grooves 100b from the upper posts 120 and the upper and lower posts 110, It is preferable that the upper post bracket 150 includes the bush member 106 as well, since the load imposed on the post can be greatly reduced.

As shown in FIGS. 5 and 6, the upper post bracket 150 includes a fastening groove 100a which is formed on both sides of the upper post bracket 150 and which surrounds the rear outer circumferential surface of the fastening hole 200, A bush member 106 having a plate structure in which a hemispherical support portion 1060 and a connection portion 1061 connecting the hemispherical support portion 1060 are integrally formed.

Of course, unlike the lower post bracket 170, the bush member 106 provided in the upper post bracket 150 maintains the position of the corresponding fastener 200 fixed, The second support bracket 160 connected to the upper end of the lower post 110 generates a strong load in the rear direction, particularly when the lower post 110 is pushed rearward from the front impact. In this case, A rear load is also generated in the upper post bracket 150 connected to the bracket 160. The bush member 106 having the hemispherical supporter 1060 supporting the front outer circumferential surface of the fastener 200 is provided on the upper post bracket 150 so that the impact of the lower post 110 is transmitted to the upper post So that transmission to the bracket 150 and the upper post 120 can be minimized.

In the meantime, a protective cover 190 having a substantially C-shaped cross-section may be disposed on the front of the lower post 110 according to the present invention so as to surround the front portion of the lower post 110. At this time, a buffer member 180 having a predetermined self-elastic force is interposed between the protective cover 190 and the lower post 110.

The protective cover 190 and the cushioning member 180 are fixedly coupled to the lower posts 110 through fastening holes 201 that penetrate both side surfaces of the lower posts 110 closely.

Here, the cushioning member 180 supports the front protective cover 190 as its own elastic force, absorbing the impact force due to the external impact, thereby canceling the impact force transmitted to the rear lower post 110. The cushioning member 180 is provided on both sides of the protective cover 190 through which the fastener 201 passes so that the protective cover 190 can move in the forward and backward directions in conjunction with the contraction and restoring force action of the cushioning member 180. [ An elongated groove 190b corresponding to the amount of elastic shrinkage in the longitudinal direction is formed.

Also, the protective cover 190 preferably has a slope formed in the bent portion extending from the front surface to the both side surfaces of the lower post 110, so that even if an external impact acts on both sides, So that the impact force is transmitted toward the buffer member 180 at the rear side.

The cushioning member 180 may be made of any material having elasticity such as rubber or resin.

As described above, since the first primary contact applied to the lower post 110 through the protective cover 190 and the impact due to the impact through the cushioning member 180 are absorbed by the secondary cover and transmitted to the rear lower post 110, The impact can be canceled.

As described above, the loading rack according to the present invention can be used not only for the primary protection of the lower cover 110 using the protective cover 190 and the cushioning member 180, but also for the protection of the lower post 110 110 and the fastening member 201 are moved rearward to prevent the lower posts 110 from being damaged from a strong impact exceeding the protection range of the cushioning member 180. The first and second support brackets 140, The upper posts 120 and the brackets 140 and 160 from the loads acting on the lower posts 110 and the upper posts 120 and the brackets 140 and 160 through the bush members 105 and 106 having the plate structure provided in the upper post bracket 150, The rigidity of the loading rack can be increased as a whole by preventing the absorbing grooves 100b and the fastening holes 200 from being damaged.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
