Description

Modular storage rack

The present invention relates to a modular storage rack, which is composed of at least four vertical pole devices and a plurality of storage layers. The storage layers and the column devices are assembled into a storage rack by clamping the column devices with the clamping pieces provided on the storage layers.

The modular storage racks disclosed in U.S. Patent Nos. 5,676,263 and 5,303,645 all use bamboo tubes as columns. The columns are provided with a number of annular grooves for the tapered clips to be inserted and positioned, and then the tapered sleeves at the corners of the storage layers are put on the outside of the clips to tighten the clips to assemble the storage layers. The storage layers on both sides of the column must be of unequal heights, making the entire storage rack look messy and disorderly.

The modular storage rack disclosed in the patent case of invention No. 1429409 of our country, "Modular Storage Rack", is composed of at least four column devices and at least two storage layers. The column device includes two parallel left and right vertical rods, and a plurality of connecting parts connecting the left and right vertical rods. The clip is provided with a lead-straight extending embedding groove, and a wing is respectively provided at the two opening ends of the embedding groove. The embedding groove of the clip can be used for the vertical rod of the column device to be embedded, so that the clip can be assembled on the column device. A C-shaped clip with an opening facing outward is respectively provided at the front and rear ends of the two side edges of the storage layer, and the C-shaped clip tightens the two wings of the clip. The mating surface between the C-shaped clip and the two wings is an inclined surface. When the storage layer moves downward, the C-shaped clip will push the two wings, so that the clip clamps the vertical rod. The C-shaped clips at the four end corners of the storage layer can be fixed on the vertical rods of the front, rear, left and right four-pillar device respectively.

In the patent No. 1429409, after being used for a period of time, the opening of the C-shaped clip on the storage rack will gradually expand, causing the storage layer to gradually sink, and eventually the storage layer will tilt or fall. In addition, in the patent No. 1429409, the clip is made of plastic material, which is not strong enough.

The main purpose of the present invention is to provide a modular storage rack that can stably mount the storage layer on the column device and improve the overall structural strength of the storage rack.

The modular storage rack provided by the present invention is composed of at least four column devices and at least two storage layers. The four end corners of each storage layer are mounted on four column devices. A clip is provided between the end corners of the storage layer and the column device. The storage layer is mounted between the column devices by sandwiching the column device between the clip and the storage layer.

The column device includes two parallel left and right vertical poles, and a plurality of horizontal connecting parts arranged between the left and right vertical poles. The two vertical poles can respectively form two left and right storage layers.

The clip has a groove extending in a straight shape, and a wing is connected to both sides of the lower half of the front and rear ends of the opening of the groove. The outer side surfaces of the two wings are inclined surfaces with the lower ends gradually protruding outward. The groove of the clip can be embedded in the vertical rod, and the opening of the groove is oriented toward the storage layer. The lower end of the clip is provided with a horizontally extending broken groove. The connecting piece of the column device can be introduced into the broken groove of the clip.

A U-shaped tightening piece with an opening facing outward is provided at the front and rear ends of both sides of the storage layer. A push-up piece is provided at the front and rear edges of the lower half of the tightening piece. The inner end surfaces of the two push-up pieces are inclined, and the upper ends thereof are gradually protruding relative to the lower ends.

The tightening pieces at the front and rear ends of the two sides of the storage layer can correspond to the outside of the clips wrapped on the front, rear, left and right column devices respectively. The inner end faces of the two top push pieces of each tightening piece respectively press against the outer side faces of the two wings of the corresponding clip. By virtue of the corresponding inclined surfaces between the top push piece and the two wings being fitted together, the clip and the tightening piece are brought close to each other, thereby clamping the vertical pole.

Please refer to Figures 1 and 2. The modular storage rack disclosed in the present invention is composed of at least four column devices 10 and at least two storage layers 20. The column device 10 includes two parallel left and right vertical poles 11, and a plurality of horizontally extending connectors 12 arranged from top to bottom. The connector 12 is arranged between the left and right poles 11 to connect the left and right poles 11 into one body. The two ends of the connector 12 are respectively fixed to the left and right poles 11, and the width of the connector 12 defines the distance between the left and right poles 11. The pole 11 of the column device 10 can be a flat round tube with arcs at both ends and a plane in the middle.

Please refer to Figure 3. The front and rear ends of the two sides of the storage layer 20 are each provided with a U-shaped tightening member 30 with an opening facing outward. The four end corners of the storage layer 20 can be respectively mounted on the vertical rods 11 of the four-pillar device 10. A clip 40 can be respectively arranged on the vertical rods 11 of the four-pillar device 10. The clip 40 has a groove 41 extending in a straight shape to allow the corresponding vertical rod 11 to be embedded. By clamping the four vertical rods 11 with the four tightening members 30 of the storage layer 20 and the corresponding four clips 40, the storage layer 20 can be mounted on the four-pillar device 10.

Please refer to Figures 4, 5 and 7. The lower end of the clip 40 is provided with a horizontally extending broken groove 42. The connecting piece 12 of the column device 10 can be introduced into the broken groove 42 of the clip 40 to limit the position of the clip 40 on the vertical rod 11. Then the clip 40 can be supported by the connecting piece 12. The lower halves of the front and rear ends of the opening of the groove 41 of the clip 40 are connected to a wing 43 and 44 on both sides. The outer side surfaces of the two wings 43 and 44 are inclined surfaces with the lower ends gradually protruding outward. The outer side surfaces 431 of the two wings 43 and 44 (see Figure 7, the outer side surface of the wing 44 is not shown in the figure) have the same slope. After the vertical bar 11 is inserted into the groove 41 of the clip 40, the opening of the groove 41 is oriented toward the storage layer 20. Since the opening of the broken groove 42 is oriented toward the front (in the state of FIG. 5), the bottom edge of the front wing 43 is higher than the bottom edge of the rear wing 44.

Please refer to Figures 4, 5 and 6. The front and rear edges of the lower half of the tightening member 30 are each provided with a push piece 31 extending toward the storage layer. The inner side end faces 311 of the two push pieces 31 are inclined. The upper ends of the inner side end faces 311 of the two push pieces 31 are gradually protruding relative to the lower ends. The inclinations of the inner side end faces 311 of the two push pieces 31 are the same. When manufacturing the tightening member 30, a metal plate can be appropriately cut and then bent into the U shape, and the tightening member 30 with the two push pieces 31 can be naturally formed. A pressure plate 32 is formed between the two push pieces 31. The two sides of the pressure plate 32 are separated from the two push plates 31, and the top end is integrally connected to the main body of the tightening member 30. The pressure plate 32 is welded to a horizontal rod 21 of the storage layer 20.

Please refer to Figures 8 to 11. The storage layer 20 assembly moves from top to bottom during the operation of the four-post device 10, so that the front and rear ends of the two sides of the storage layer 20 can correspond to the outside of the clips 40 on the front, rear, left and right post devices 10. Meanwhile, the front and rear end plates of the tightening member 30 are respectively covered on the outside of the front and rear end surfaces of the clip 40. The inner side end surfaces 311 of the two push pieces 311 of each tightening member 30 are respectively pressed against the outer side surfaces 431 of the two wing pieces 43, 44 of the corresponding clip 40. During the downward movement of the storage layer 20, the corresponding inclined surfaces of the top push piece 31 and the two wings 43 and 44 fit together and push each other, so that the clamping piece 30 and the tightening member 40 are close to each other and the vertical rod 11 is clamped. Then the storage layer 20 can be assembled on the four vertical rods 11.

The column device 10 has two left and right upright poles 11, and two left and right storage layers 20 can be respectively installed on the two upright poles 11, and the two storage layers 20 can be at the same height, as shown in FIG. 12. In this way, the assembled storage rack can present a coordinated and beautiful shape.

In summary, in the combined storage rack provided by the present invention, when the storage layer 20 moves downward relative to the clip 40 until it can no longer move, it means that the clip 40 and the tightening member 30 have completely clamped the vertical rod 11. The connection strength between the storage layer 20 and the vertical rod 11 is high and reliable. Therefore, compared with the first patent No. 1429409, the present invention is higher in structural strength and durability.
