The present invention relates to units for storage and, particularly, to an improved assembly storage rack.
For aesthetics, the support legs 91 and the rail members 92 are usually electroplated first, and then are welded to each other. However, welding traces will be inevitably formed between the support legs 91 and the rail members 92 due to the curved outer periphery of the support leg 91, affecting the appearance aesthetics.
Further, each of the rail members 92 must be manufactured individually and is individually welded to the support legs 91 to cause a complex manufacturing process.
The volume of rack 90 cannot reduce due to the support legs 91 and the rail members 92 weldedly connected with each other, leading to higher warehouse cost and transportation cost.
The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.
An assembly storage rack includes two pair of support legs, two rail members, and a plurality of drawers. Each rail member includes a pair of connection portions and a plurality of rail portions. The pair of connection portions and the plurality of rail portions are integrally formed with each other. The pair of connection portions and the plurality of rail portions are respectively formed at two opposite sides of each rail member. The pair of connection portions of each rail member is detachedly mounted to each pair of support legs. Each drawer is slidably mounted between two rail portions of the two rail members facing each other.
Each rail member may be formed by an injection molding process.
Each rail member may be made of plastic.
Moreover, the pair of connection portions of each rail member has a pair of connection slots abutable against outer peripheries of each pair of support legs.
Each connection slot may have an arc-shaped slot-face.
The pair of connection portions of each rail member is threadedly connected to each pair of support legs.
In an example, each pair of support legs is straight metal cylinders extending along longitudinal straight lines. The pair of connection portions of each rail member extends along the longitudinal straight lines to correspond to each pair of support legs.
In another example, each pair of support legs is curved metal cylinders extending along longitudinal curved lines. The pair of connection portions of each rail member extends along the longitudinal curved lines to correspond to each pair of support legs.
The assembly storage rack further includes a pair of support rods threadedly mounted between top ends of the two pair of support legs, and a cap member detachedly mounted on the pair of support rods.
Each rail portion has a sliding recess extending therethrough. Each drawer includes a pair of guiding portions formed at two opposite sides thereof. The pair of guiding portions of each drawer is slidably mounted in two sliding recesses of two rail portions of the two rail members facing each other.
The present invention will become clearer in light of the following detailed description of illustrative embodiments of this invention described in connection with the drawings.
Each pair of support legs 20 may be straight metal cylinders extending along longitudinal straight lines, and includes a plurality of threaded holes 21.
Each rail member 30 is made of plastic and is formed by an injection molding process. Thus, the two rail members 30 are designed in a modular way to reduce the manufacturing cost. Each rail member 30 includes a pair of connection portions 31 and a plurality of rail portions 32. The pair of connection portions 31 and the plurality of rail portions 32 are integrally formed with each other to reduce assembly time and manufacturing steps. The pair of connection portions 31 and the plurality of rail portions 32 are respectively formed at two opposite sides of each rail member 30. The pair of connection portions 31 extends along the longitudinal straight lines to correspond to each pair of support legs 20. The pair of connection portions 31 is detachedly mounted to each pair of support legs 20. Further, the pair of connection portions 31 may be threadedly mounted to each pair of support legs 20 to reduce the storage volume. The pair of connection portions 31 has a pair of connection slots 33 each having an arc-shaped slot-face abutable against outer peripheries of each pair of support legs 20. The plurality of rail portions 32 is parallel to each other and is equally spaced from each other longitudinally. Each rail portion 32 has a sliding recess 34 horizontally extending therethrough.
Each drawer 40 includes a pair of guiding portions 41 formed at two opposite sides thereof. The pair of guiding portions 41 is slidably mounted in two sliding recesses 34 of two rail portions 32 of the two rail members 30 facing each other.
The pair of support rods 50 is threadedly mounted between top ends of the two pair of support legs 20.
The cap member 60 is detachedly mounted on the pair of support rods 50 and may be used for placing commodities.
The plurality of threaded member 70 extends through the pair of connection portions 31 of each rail member 30, and then engages into the plurality of threaded holes 21 of each pair of support legs 20 to cause the pair of connection portions 31 to be threadedly mounted to each pair of support legs 20.
Although specific embodiments have been illustrated and described, numerous modifications and variations are still possible without departing from the scope of the invention. The scope of the invention is limited by the accompanying claims.
