Sectional shelf

Abstract

A sectional shelf is provided, which includes a plurality of shelves each having at least two hollow fastening parts and being stacked one by one to form desired shelf compartments, an upper portion of each shelf being opened, a plurality of hollow support members located between the shelves for supporting the shelves, an upper coupling member with one end inserted into an upper end of each support member and the other end inserted into a lower end of each support member, a threaded portion being formed on an upper end of the upper coupling member, and a lower coupling member with one end inserted into the lower end of each support member and the other end inserted into the upper end of each support member, a threaded portion being formed on a lower end of the lower coupling member and threadedly engaged with the threaded portion of the upper coupling member. The sectional shelf can permit easy assembling and disassembling of a plurality of shelves, and stably maintain the shape of the shelves assembled by support members and/or coupling members.

       2 . The sectional shelf as claimed in  claim 1 , wherein the upper and lower coupling members have a stop portion formed on a middle portion of an outer periphery of each of the upper and lower coupling members, and the stop portion has a diameter larger than an inner diameter of the support member and fastening part. 
   
   
       3 . The sectional shelf as claimed in  claim 1 , wherein an upper end cover is mounted on an upper end of each fastening part of the uppermost shelf, and the upper end cover is provided on a lower portion thereof with a threaded portion which is threadedly engaged with the threaded portion of the upper coupling member. 
   
   
       4 . The sectional shelf as claimed in  claim 1 , wherein a lower end cover is mounted on a lower end of each fastening part of the lowermost shelf, and the lower end cover has a stepped stop portion of a diameter larger than the inner diameter of the fastening part, in which the stop portion is provided with a threaded portion which is threadedly engaged with the threaded portion of the lower coupling member. 
   
   
       5 . The sectional shelf as claimed in  claim 4 , wherein a base member is mounted on a lower end of the lower end cover, and the base member has a body of a diameter larger than the inner diameter of the fastening part, and a threaded portion formed on an upper end of the body which is threadedly engaged with the threaded portion of the stop portion. 
   
   
       6 . The sectional shelf as claimed in  claim 4 , wherein a caster bracket having a caster is detachably coupled to the lower end of the lower end cover, and the caster bracket has a stopper for restraining rotation of the caster. 
   
   
       7 . A sectional shelf comprising:
 a plurality of shelves each having at least two hollow fastening parts and being stacked one by one to form desired shelf compartments, an upper portion of each shelf being opened; and   a plurality of support members located between the shelves for supporting the shelves, in which a lower end of the support member is inserted in an upper end of the fastening part and an upper end is inserted in a lower end of the fastening part,   in which each of the support members is provided on an outer periphery thereof with upper and lower bosses each having a diameter larger than an inner diameter of the fastening part and spaced apart from each other at a certain interval, and in which the upper boss is caught by the lower end of the fastening part which is positioned on an upper portion of the support member, and the lower boss is caught by the upper end of the fastening part which is positioned on a lower portion of the fastening part.   
   
   
       8 . The sectional shelf as claimed in  claim 7 , wherein the upper and lower bosses are formed by compressing the support member in a longitudinal direction, respectively. 
   
   
       9 . The sectional shelf as claimed in  claim 7 , wherein a support leg is mounted on a lower end of each fastening part of the lowermost shelf, and the support leg is provided at a middle portion thereof with a stop portion having a diameter large than an inner diameter of the fastening part. 
   
   
       10 . The sectional shelf as claimed in  claim 9 , wherein a caster bracket having a caster is detachably coupled to the lower end of the support leg, and the caster bracket has a stopper for restraining rotation of the caster. 
   
   
       11 . A sectional shelf comprising:
 a plurality of shelves each having at least two hollow fastening parts and being stacked one by one to form desired shelf compartments, an upper portion of each shelf being opened;   a plurality of hollow support members located between the shelves for supporting the shelves, in which a lower end of the support member of the upper shelf is inserted in an upper end of the fastening part and an upper end is inserted in a lower end of the fastening part of the lower shelf;   an upper coupling member having an engaging portion inserted in the upper end of each support member; and   a lower coupling member having an engaging portion inserted in the lower end of each support member.   
   
   
       12 . The sectional shelf as claimed in  claim 11 , wherein the engaging portion of the upper coupling member is provided on an upper end thereof with a flange having a diameter equal to an outer diameter of the support member and a threaded portion corresponding to a threaded portion of the upper coupling member. 
   
   
       13 . The sectional shelf as claimed in  claim 11 , wherein the engaging portion and threaded portion of the lower coupling member are provided on upper ends thereof with a flange having a diameter equal to an outer diameter of the support member, respectively.
