Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • 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.
  • 2. Description of the Related Art
  • 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.
  • 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.
  • The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.
    • SUMMARY OF THE INVENTION
  • 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.
  • It is another object of the present invention to provide an expandable modular shelf system which requires no aid of hand tools in assembly of the system.
  • It is yet another object of the present invention to provide an expandable modular shelf system which provides a sturdy structure.
  • 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.
  • Other objectives, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to FIGS. 1 through 6, an expandable modular shelf system comprises a shelf 2 having a frame 202 with four corners defining four engaging portions 203 correspondingly and a wall 201 extending between the frame 202 but leaving the engaging portions 203 exposed. It is to be understood that the wall 201 may serve as a shelving surface. A joint assembly 1 includes two cap members 10 of the same configuration joined together at namely their mating surfaces 11. The mating surface 11 includes two connections 14 with one connection 14 formed of a stud and the other formed of a recess, and with the stud-like connection 14 of one cap member 10 is engaged in the recess-like connection 14 of another cap member 10. The mating surface 11 further includes a plurality of grooves 15 thereon. Each groove 15 of one cap member 10 and the corresponding groove 15 of another cap member 10 are in concert to receive one engaging portion 203. Additionally, the groove 15 has a curved section close to the center thereof and is substantially L-shaped, and extends outward to the perimeter thereof.
  • The joint assembly 1 further includes a rod 20 having a first end received in a cavity 13 of one cap member 10 and a second end. It is to be understood that the rod 20 may serve as a leg with the second end against the supporting surface. A connecting member 30 is provided to join two cap members 10 and the rod 20 in a way to retrain the cap members 10 from detachment. In the preferred embodiment, the connecting member 30 is insertably engaged in through holes 12 of two mated cap members 10 correspondingly and has first section and a second section separated by a flange 31 which extends transversely thereto. The flange 31 is disposed outside the through hole 12 of one cap member 10 and includes a diameter larger than that of the through hole 12. Additionally, the first end of the rod 20 includes a threaded section 21 threadly engaged with the second section of the connecting member 30.
  • Referring to FIGS. 1 through 4, the expandable modular shelf system may comprise a rail 3 including a middle portion 301 and two end portions 302 bent with respect thereto received in two horizontally spaced cap members 10. It is to be understood that the middle portion 301 may serve as a handle. The end portion 302 may include a threaded section 303 threadly engaged with the first section of the connecting member 30.
  • Moreover, as best shown in FIG. 7 and FIGS. 13-16, each rod 20 is adapted to further receive another joint assembly 1 at the second end thereof, whereby the number of shelves can be increased vertically. Also, the joint assembly is adapted to further receive at least one shelf, thereby increasing the number of shelves horizontally.
  • FIGS. 8 and 9 show a second embodiment of 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.
  • FIGS. 10 and 11 show a third embodiment of 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.
  • 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.
  • While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of invention and the scope of invention is only limited by the scope of accompanying claims.
