The matters defined in the description, such as the detailed construction and elements, are nothing but specific details provided to assist those of ordinary skill in the art in a comprehensive understanding of the invention, and thus the present invention is not limited thereto.
  • FIG. 1 is a perspective view illustrating a sectional shelf according to a first embodiment of the present invention, and FIG. 2 is an exploded perspective view illustrating the sectional shelf in FIG. 1.
  • The sectional shelf according to this embodiment includes, as shown in FIGS. 1 and 2, rectangular shelves which are stacked in four compartments, and four supports which are located at four corners of the shelves. It would be understood to one skilled in the art that the shape and number of the assembled shelves and the number of the supports may be varied, if necessary.
  • Referring to FIGS. 1 and 2, the sectional shelf according to this embodiment includes shelves 10 each having at least two fastening parts 11 and stacked one by one to form desired compartments, support members 20 located between the shelves 10 for supporting the shelves 10, an upper coupling member 30 with one end inserted into an upper end of each support member 20 and the other end inserted into a lower end of each support member 20, and a lower coupling member 40 with one end inserted into a lower end of each support member 20 and the other end inserted into an upper end of each support member 20.
  • The shelf 10 has an upper portion opened to easily store articles and a lattice-like lower portion made of horizontal ribs 12 and vertical ribs 13 which are made of corrosion-proof metal, such as stainless steel.
  • Also, the shelf 10 has an upper frame 14 and a lower frame 15 which are disposed on an edge of the shelf 10, and a support frame 16 interposed between the upper frame 14 and the lower frame 15 for maintaining the whole shape of the shelf 10 and preventing things from dropping from the shelf.
  • The fastening parts 11 installed to front and rear corners of the shelf 10 is adapted to engage to the support member 20, and is formed in a pipe with opened upper and lower portions.
  • When the shelves 10 are stacked in several shelf compartments, as shown in FIGS. 1 and 2, the shape of the lowermost shelf, the middle shelf, or the uppermost shelf may be changed.
  • The support member is interposed between the fastening part of the shelf and the fastening part of a neighbor shelf, and is made of a hollow pipe.
  • The upper coupling member 30 is to couple the support member with the lower end of the fastening part of each shelf. The upper coupling member 30 has a stop portion 41 formed on a middle portion of an outer periphery of the upper coupling member. The stop portion has a diameter larger than an inner diameter of the support member 20 and fastening part 11, so as to prevent the upper coupling member 30 from being fully inserted in the support member 20 and the fastening part 11.
  • Specifically, the upper coupling member 30 consists of an upper coupling part 32 which is inserted in the fastening part 11 of the shelf upwardly positioned and a lower coupling part 33 which is inserted in the support frame downwardly positioned, on the basis of the stop portion.
  • Preferably, the diameter of the stop portion 31 is equal to an outer diameter of the support member 20, so that the coupled portion of the stop portion 31 and the support member 20 has a smooth appearance even though the stop portion 31 is outwardly exposed.
  • The upper coupling portion 32 is provided on an inner periphery thereof with a threaded portion 32 a which is threadedly engaged with a threaded portion of the lower coupling member 40 of the upper shelf.
  • The lower coupling member 40 is to couple the support member 20 with the upper end of the fastening part 11 of each shelf 20. The lower coupling member 40 has an upper engaging portion 42 at an upper end which is inserted in the support member 20 of the upper shelf, a lower engaging portion 43 at a lower end which is inserted in the fastening part 11 of the lower shelf, and a stop portion 41 formed on a middle portion of an outer periphery. The stop portion has a diameter larger than an inner diameter of the support member 20 and fastening part 11, so as to prevent the lower coupling member 40 from being fully inserted in the support member 20 and the fastening part 11. Consequently, when the lower coupling member 40 is inserted between the support member 20 and the adjacent support member 20, the stop portion 41 is outwardly exposed.
  • In this instance, like the stop portion 31 of the upper coupling member 30, the diameter of the stop portion 41 is equal to an outer diameter of the support member 20, so that the coupled portion of the stop portion 41 and the support member 20 has a smooth appearance when the support members 20 are coupled to each other.
  • The lower engaging portion 43 is provided on a lower end thereof with a threaded portion 43 a which is threadedly engaged with the threaded portion 32 a of the upper coupling member 30 of the lower shelf.
  • An upper end cover 50 is mounted on an upper end of each fastening part 11 of the uppermost shelf. The upper end cover 50 is provided on a lower portion thereof with a threaded portion 52 which is threadedly engaged with the threaded portion 32 a of the upper coupling member 30.

  • A lower end cover 60 is mounted on a lower end of each fastening part 11 of the lowermost shelf. The lower end cover 60 has an inserting portion 61 which is inserted in the fastening part 11 of the lowermost shelf 10. The inserting portion has a stepped stop portion 62 of a diameter larger than the inner diameter of the fastening part 11, thereby preventing the lower end cover 60 from being fully inserted in the fastening part 11.
  • In this instance, the inserting portion 61 and the stop portion 62 are provided with threaded portions 61 a and 62 a which are threadedly engaged with the threaded portion 43 a of the lower coupling member 40 and the threaded portion 72 of a base member 70.
  • The base member 70 is mounted on the lower end of the lower end cover 60. The base member 70 has a body 71 of a diameter larger than the lower end cover and a threaded portion 72 formed on an upper end of the body 71.
  • The body 71 has a flat bottom surface to stably support the shelf 10. Preferably, the body 71 is made of a synthetic rubber, for example, so as to prevent slippage of the base member.
  • The threaded portion 72 is threadedly engaged with the threaded portion 62 a formed on the inner periphery of the stop portion 62 of the lower end cover 60. Consequently, the sectional shelf of the present invention can be stably positioned on an uneven ground by rotating the threaded portion 72 of the base member so as to adjust a height of the sectional shelf.
  • A process of assembling the sectional shelf according to this embodiment of the present invention will now be described with reference to FIGS. 1 and 2.
  • Since the assembling process is identical irrespective of the number of the shelves to be stacked, the process of assembling two shelves will now be described.
  • The lower end cover 60 is inserted in the lower end of the fastening part 11 of the lower shelf, and the lower end cover 60 is inserted in the lower end of the fastening part 11 and threadedly engaged with the threaded portion 43 a of the lower coupling member 40 of the upper shelf.
  • Then, the lower end of the support member 20 is inserted in the upper end of the lower coupling member 40, and the lower end of the upper coupling member 30 is inserted in the upper end of the support member 20.
  • If the upper coupling member 30 is inserted in the upper end of the support member 20, the threaded portion 32 a of the upper coupling member 30 is inserted in the fastening part 11 of the upper shelf.
  • The upper end cover 50 is inserted in the upper end of the fastening part of the upper shelf 11, and then, the threaded portion 52 is engaged with the threaded portion 32 a of the upper coupling member 30 by rotating the upper end cover 50.
  • After the upper coupling member 30 and the lower coupling member 40 are fixed to upper and lower ends of the support member 20, the support member 20 is fastened to the shelf 10.
  • FIGS. 3 and 4 illustrate a sectional shelf according to a second embodiment of the present invention. The sectional shelf according to this embodiment includes shelves 10 each having at least two fastening parts 11 at and edge thereof and stacked one by one to form desired shelf compartment, and support members 20 located between the shelves 10 for supporting the shelves 10, in which a lower end of the support member 10 is inserted in an upper end of the fastening part 11 and an upper end is inserted in a lower end of the fastening part 11.
  • Explaining the sectional shelf shown in FIGS. 3 and 4, parts which are identical to those shown in FIGS. 1 and 2 are shown by corresponding reference numerals.
  • Since the construction of the shelf 10 in FIGS. 3 and 4 is substantially similar to that shown in FIGS. 1 and 2, the shelf 10 will not be described herein.
  • The support member 20 is made of a hollow pipe, and is located at four corners of the shelf, respectively, as shown in FIGS. 1 and 2, but it may be easily modified by those skilled in the art.
  • The support member 20 is provided on an outer periphery thereof with upper and lower bosses 21 and 22 having a diameter larger than an inner diameter of the fastening part 11 and spaced apart from each other at a certain interval. An upper coupling part 23 which is engaged to the lower end of the fastening part 11 of the shelf 10 is provided on the upper portion of the upper boss 21, and a lower coupling part 24 which is engaged to the upper end of the fastening part 11 of the shelf 10 is provided on the lower portion of the lower boss 22.
  • The upper and lower bosses 21 and 22 are formed by compressing the support member 20 in a longitudinal direction. Preferably, the bosses 21 and 22 have a diameter equal to an outer diameter of the fastening part 11.
  • The upper boss 22 is caught by the lower end of the fastening part 11 of the upper shelf, while the lower boss 24 is caught by the upper end of the fastening part 11 of the lower shelf.
  • An upper end cover 50′ is mounted on an upper end of each fastening part 11 of the uppermost shelf. The upper end cover 50′ has a head 51′ of a diameter larger than the inner diameter of the fastening part 11 and equal to the outer diameter of the fastening part 11, thereby preventing the upper end cover 50′ from being fully inserted in the fastening part 11.
  • The construction of the upper end cover shown in FIGS. 3 and 4 is slightly different from that of the upper end cover shown in FIGS. 1 and 2, in which a threaded portion is not formed on the lower portion 52′ of the upper end cover 50′.
  • A support leg 80 is mounted on a lower end of each fastening part 11 of the lowermost shelf. The support leg 80 is provided at a middle portion thereof with an annular boss 81 for catching the fastening part 11, thereby preventing the support leg 80 from being fully inserted in the fastening part 11.
  • The lower end of the support leg 80 is coupled to a slippage prevention member 84 made of a synthetic rubber, so as to prevent slippage of the support leg.
  • Reference numerals 82 and 83 indicate an upper engaging part inserted in the lower end of the fastening part of the lowermost of the shelf and a lower engaging part inserted in the slippage prevention member, respectively.
  • FIGS. 5 and 6 illustrate a sectional shelf according to a third embodiment of the present invention. The sectional shelf according to this embodiment includes shelves 10 each having at least two fastening parts 11 at an edge thereof and stacked one by one to form desired shelf compartment, and support members 20 located between the shelves 10 for supporting the shelves 10, in which a lower end of the support member 10 is inserted in an upper end of the fastening part 11 and an upper end is inserted in a lower end of the fastening part 11.
  • Explaining the sectional shelf shown in FIGS. 5 and 6, parts which are identical to those shown in FIGS. 1 to 4 are shown by corresponding reference numerals.
  • Since the construction of the shelf 10 in FIGS. 3 and 4 is substantially similar to that shown in FIGS. 1 and 2, the shelf 10 will not be described herein.
  • The support member 20 is made of a hollow pipe, and is located at four corners of the shelf, respectively, but it may be easily modified by those skilled in the art.
  • The support member 20 is provided on an outer periphery thereof with upper and lower bosses 21 and 22 having a diameter larger than an inner diameter of the fastening part 11 and spaced apart from each other at a certain interval. The upper and lower bosses 21 and 22 are formed by compressing the support member 20 in a longitudinal direction. Preferably, the bosses 21 and 22 have a diameter equal to an outer diameter of the fastening part 11.
  • The upper boss 22 is caught by the lower end of the fastening part 11 of the upper shelf, while the lower boss 24 is caught by the upper end of the fastening part 11 of the lower shelf.
  • An upper coupling member 30′ is inserted and engaged to the upper end of each support member 20, and a lower coupling member 40′ is inserted and engaged to the lower end of each support member 20.
  • The upper coupling member 30′ has an engaging portion 31′ of an outer diameter corresponding to the inner diameter of the support member 20, and the engaging portion 31′ is provided with a threaded portion 31 a′ on an inner periphery thereof. The engaging portion 31′ is provided on an upper end thereof with a flange 32′ which protrudes outwardly from the periphery thereof at a certain length, so as to prevent the upper coupling member 30′ from being fully inserted in the support member 20. Preferably, the flange 32′ has a diameter equal to the outer diameter of the support member 20.
  • Similarly, the lower coupling member 40′ has an engaging portion 41′ of an outer diameter corresponding to the inner diameter of the support member 20, and the engaging portion 41′ is provided with a threaded portion 41 a′ on an inner periphery thereof. The engaging portion 41′ is provided on an upper end thereof with a flange 42′ which protrudes outwardly from the periphery thereof at a certain length, so as to prevent the lower coupling member 40′ from being fully inserted in the support member 20.
