Benefits of technology

[0007]It is therefore an object of the present invention to provide an expandable modular shelf system having shelves which may be increased as the need arises.
[0009]It is yet another object of the present invention to provide an expandable modular shelf system which provides a sturdy structure.
[0010]Accordingly, the present invention discloses an expandable modular shelf system comprises at least one shelf which has a plurality of engaging portions adapted to be engaged with a plurality of joint assemblies correspondingly. Each joint assembly includes two cap members mated together to receive one engaging portion therebetween, a rod connected to one of the cap members, and a connecting member joining the two cap members and the rod in a way to retrain the cap members from detachment. The joint assembly is adapted to further receive at least one shelf, thereby increasing the number of shelves horizontally. The rod is adapted to further receive a joint assembly, whereby the number of shelves can be increased vertically.

Problems solved by technology

While the modular shelf system provides a sturdy attachments between the joints and the tubes, a problem of such a system is that it requires the aid of hand tools to secure the threaded rod to the arcuate plate, which is cumbersome for a DIY assembler.

second embodiment

[0030]FIGS. 8 and 9 show the present invention. The embodiment shows an alternate type of shelf 2′ being used. The shelf 2′ includes a wall 201′ having an array of holes disposed thereof and defines an engaging portion 203′ between the edge of a corner and the hole adjacent to that corner.

third embodiment

[0031]FIGS. 10 and 11 show the present invention. In this embodiment, the expandable modular shelf system further includes a panel 4 adapted to be disposed perpendicular to the shelf 2. The panel 4 has a wall section 401 with edges having bars 402 disposed therealong correspondingly, and each bar 402 has two legs 403 bent with respect thereto receivable by two joint assemblies 1 correspondingly.

[0032]FIG. 12 shows a fourth embodiment of the present invention. The expandable modular shelf is similar to the third embodiment except that the wall section 401 is eliminated.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a modular shelf system, and in particular, to a modular shelf system including shelves which may be increased as the need arises and assembled without aid of hand tools.[0003]2. Description of the Related Art[0004]Taiwanese Patent No. M302642 discloses a known modular shelf system including a plurality of joints and tubes. Each joint includes a plurality of engaging portions on which the plurality of tubes receive correspondingly, and each engaging portion includes two opposed arcuate plates with one of the arcuate plate having a hole formed thereof for allowing engagement of a threaded rod. The threaded rod is inserted until it touches the inner wall of opposite arcuate plate. When the tube is engaged with the engaging portion of the joint, the thread rod and two arcuate plates will ensure secure attachment therebetween.[0005]While the modular shelf system provides a sturdy attachments ...
