Description

The present invention relates to an assembly rack that combines at least four support devices and multiple shelves. The shelves and support devices are assembled into a rack by clamping the support devices between tension members provided on the shelves and clamping pieces on the support devices.

Patents such as U.S. Patent Nos. 5,676,263 and 5,303,645 disclose prefabricated racks that use bamboo-type tubing as support posts. The support posts are provided with a number of annular grooves for positioning tapered clamping pieces, after which tapered sleeves at the end corners of the shelves are sleeved onto the outside of the clamping pieces, and the clamping pieces are tightened to erect the shelves. The shelves erected on both sides of the support posts are of different heights, making the overall rack look untidy and disorganized.

The assembled rack disclosed in JP 2012-157686 A is a combination of at least four support devices and at least two shelves. The support device includes two support devices arranged side by side on the left and right, and a plurality of connecting members connecting the two support devices on the left and right. The clamping piece is provided with a fitting groove extending vertically, and one wing piece is provided at each of the opening ends of the fitting groove. The fitting groove of the clamping piece is fitted into the support of the support device, and the clamping piece is assembled to the support device. The front and rear ends of both sides of the shelf are provided with C-clamps that open outward, and these C-clamps clamp the two wing pieces of the clamping piece. Since the mating surface of the C-clamp with the two wing pieces is an inclined surface, when the shelf moves down, the C-clamp pushes in the two wing pieces and clamps the clamping piece to the support. The C-clamps at the four end corners of the shelf can be fixed to the supports of the four support devices on the front, rear, left, and right, respectively.

In the invention of JP 2012-157686, the opening of the C-clamp on the rack gradually opens and expands after a period of use, causing the shelf to gradually sink and ultimately tilt or fall. Also, in the invention of JP 2012-157686, the clamping piece is made of a plastic material and is not strong enough.

The main objective of the present invention is to provide an assembly rack in which shelves can be stably mounted on a support device, improving the overall structural strength.

The assembled rack provided by the present invention is composed of at least four support devices and at least two shelves. The four end corners of each shelf are mounted on the four support devices. A clamping piece is provided between the end corners of the shelf and the support device, and the shelf is mounted between the support devices by clamping the support device between the clamping piece and the shelf.

The support device includes two parallel support columns on the left and right, and multiple horizontal connecting members arranged between the left and right support columns. The two support columns can support two shelves on the left and right, respectively.

The clamping piece has a vertically extending groove, and wing pieces are connected to both sides of the lower half of the front and rear ends where the groove opens. The outer surfaces of the two wing pieces are sloped, with the lower ends gradually protruding outward. The groove of the clamping piece is embedded in the support, and the opening of the groove is shaped to face the shelf. A horizontally extending breaking groove is provided at the lower end of the clamping piece. The connecting member of the support device can be introduced into the breaking groove of the clamping piece.

At the front and rear ends of both sides of the shelf, there is a U-shaped tension member with its opening facing outward. A protruding piece is provided at the front and rear edges of the lower half of the tension member. The inner end faces of the two protruding pieces are sloped, and their upper ends protrude gradually from the lower end.

The tensioning members at the front and rear ends of both sides of the shelf can correspond to the outside of the clamping pieces covered by the front, rear, left and right support devices. The inner end faces of the two protruding pieces of each tensioning member are abutted against the outer faces of the two wing pieces of the corresponding clamping piece. The fit of the corresponding slopes between the protruding pieces and the two wing pieces brings the clamping pieces and tensioning members closer to each other to clamp the support.

The present invention allows the shelves to be stably mounted on the support device, improving the overall structural strength, and allowing the assembled rack to be coordinated and present a beautiful appearance.

Please refer to Figures 1 and 2. The assembled rack disclosed in the present invention is composed of at least four support devices 10 and at least two gills 20. The upright device 10 has two vertical supports 11 arranged side by side on the left and right, and a plurality of connecting members 12 extending horizontally from top to bottom. The connecting member 12 is disposed between the two supports 11 on the left and right, and the two supports 11 on the left and right are integrally connected. Both ends of the connecting member 12 are fixed to the left and right supports 11, respectively, and the width of the connecting member 12 determines the distance between the left and right supports 11. The support 11 of the support device 10 can be a flat circular tube with both ends being circular arcs and a flat center.

Please refer to FIG. 3. A U-shaped tension member 30 with an opening facing outward is provided at the front and rear ends of both sides of the shelf 20, and the four end corners of the shelf 20 can be spanned across the supports 11 of the four support devices 10. The supports 11 of the four support devices 10 can each be provided with a clamping piece 40, and the clamping piece 40 has a vertically extending groove 41 that allows the corresponding support 11 to be fitted into it. The four tension members 30 of the shelf 20 clamp the four corresponding clamping pieces 40 and the four supports 11, allowing the shelf 20 to be spanned across the four support devices 10.

Please refer to Figures 4, 5 and 7. A horizontally extending groove 42 is provided at the lower end of the clamping piece 40. The connecting member 12 of the support device 10 can be introduced into the groove 42 of the clamping piece 40 to determine the position of the clamping piece 40 on the support 11, and the clamping piece 40 can be supported by the connecting member 12. The groove 41 of the clamping piece 40 has wings 43 and 44 connected to both sides of the lower half of the front and rear ends of the opening. The outer surfaces of the two wings 43 and 44 are inclined surfaces whose lower ends gradually protrude outward, and the inclination of the outer surfaces 431 of the two wings 43 and 44 (see Figure 7, outer surfaces of the wings 44, not shown) is the same. The groove 41 of the clamping piece 40 is such that the opening of the groove 411 faces the shelf 20 after the support 11 is fitted. Because the opening of the break groove 42 faces forward (as in the state shown in FIG. 5), the bottom edge of the front wing piece 43 is higher than the bottom edge of the rear wing piece 44.

Please refer to Figures 4, 5 and 6. The front and rear edges of the lower half of the tension member 30 are provided with protruding pieces 31 extending toward the shelf. The inner end faces 311 of the two protruding pieces 31 are inclined, and the upper ends of the inner end faces 311 of the two protruding pieces 31 gradually protrude relative to the lower ends. The inclinations of the inner end faces 311 of the two protruding pieces 31 are the same. When making the tension member 30, a metal plate can be cut appropriately and then bent into a U-shape, so that the tension member 30 having two protruding pieces 31 can be naturally formed. A pressing plate 32 is formed between the two protruding pieces 31, and the two sides of the pressing plate 32 and the two protruding pieces 31 are separate, and the tip is integrally connected to the tension member 30 body. The pressing plate 32 is integrally welded to the horizontal pillar 21 of the shelf 20.

Please refer to Figures 8 to 11. In the operation of hanging the shelf 20 on the four support devices 10, in order to move from top to bottom, the front and rear end tension members 30 on both sides of the shelf 20 can correspond to the outside of the clamping pieces 40 covered by the front, rear, left and right support devices 10, respectively. Meanwhile, the front and rear end plates of the tension members 30 are respectively covered on the outside of the front and rear end faces of the clamping pieces 40. The inner end faces 311 of the two protruding pieces 31 of each tension member 30 are respectively abutted against the outer faces 431 of the two wing pieces 43, 44 of the corresponding clamping pieces 40. In the process of moving the shelf 20 downward, the corresponding slopes of the protruding piece 31 and the two wing pieces 43, 44 are stuck together and pressed against each other, so that the clamping pieces 40 and the tension members 30 approach each other and clamp the support 11. Therefore, the shelf 20 can be hung on the four support columns 11.

The support device 10 has two supports 11 on the left and right, and as shown in Figure 12, two shelves 20 on the left and right can be provided and arranged at the same height. This allows the assembled rack to be coordinated and present a beautiful appearance.

In summary, the assembled rack provided by the present invention indicates that when the jaws 20 move relative to the clamping piece 40 so that they cannot descend, the clamping piece 40 and the tensioning member 30 completely clamp the support 11. In other words, the connection strength between the shelf 20 and the support 11 is high and reliable. Therefore, the present invention has higher structural strength and durability than the first disclosed invention in JP 2012-157686 A.
