Sectional rack

Abstract

A sectional rack includes at least four vertical supports, at least two shelves, and a plurality of clamping members. Each of the vertical supports includes two laterally juxtaposed posts. Each of the clamping members defines a vertically extended receiving recess and has two wing portions laterally extended from two opposite lateral edges of an open side of the receiving recess. The receiving recess is sized for one post of the vertical support to partially set therein, allowing the clamping member to assemble to the vertical support. Each of the shelves is provided at each of four corners with an outward-opened C-shaped clamping member for tightly fitting around and thereby pushing the two wing portions of the clamping member toward each other for firmly clamping the post in the receiving recess, so that the four corners of the shelf are firmly connected to the posts of the four vertical supports.

1 . A sectional rack, comprising at least four vertical supports, at least two shelves, and a plurality of clamping members;
 each of the vertical supports including two laterally juxtaposed posts, and a plurality of vertically equally spaced connecting members connected to between the two laterally juxtaposed posts;   each of the clamping members defining at an inside with a vertically extended receiving recess, and having two wing portions separately laterally extended from two opposite lateral edges of an open side of the receiving recess; the receiving recess being sized for one post of the vertical support to partially set therein, allowing the clamping member to assemble to the vertical support with the open side of the receiving recess facing toward the shelf connected to between the four vertical supports and be supported on the vertical supports; each of the two wing portions having a width that is increased from an upper end to a lower end of the wing portion, such that a laterally outer end surface of the wing portion is a gradually downward outward inclined surface; and the wing portion having an outside surface that is also a gradually downward outward inclined surface; and   each of the shelves being provided at front and rear corners at two lateral sides thereof with a C-shaped clamping member each; the C-shaped clamping members being located on the shelf with an opening thereof facing laterally outward; each of the C-shaped clamping members including a pair of hooking portions facing toward each other to define the opening therebetween; two opposite inner end surfaces of an inner space enclosed in the C-shaped clamping member being downward outward inclined surfaces, so that a width of the inner space of the C-shaped clamping member measured between the two opposite inner end surfaces gradually increases from top to bottom of the C-shaped clamping member, and the two inclined inner end surfaces of the C-shaped clamping member having a gradient the same as that of the two laterally outer end surfaces of the two wing portions; an inside surface of each of the two hooking portions facing toward the inner space of the C-shaped clamping member being a downward and outward inclined surface, and the inside surfaces of the hooking portions having a gradient the same as that of the two outside surfaces of the two wing portions of the clamping member;   whereby when the C-shaped clamping members provided at the front and rear corners at two lateral sides of the shelf are correspondingly externally fitted around the clamping members assembled to the posts of the four vertical supports, the two inclined inner end surfaces of each of the C-shaped clamping members tightly bear on the laterally outer end surfaces of the two wing portions of the corresponding clamping member, and the inclined inside surfaces of the two hooking portions of each of the C-shaped clamping members tightly bear on the outside surfaces of the two wing portions of the corresponding clamping member, so that the wing portions are pushed toward each other to move toward the shelf and reduce a size at the open side of the receiving recess on the clamping member, enabling the clamping members to tightly clamp on the posts of the vertical supports.   
     
     
         2 . The sectional rack as claimed in  claim 1 , wherein each of the clamping members further includes two vertically extended protruded blocks that are laterally symmetrically provided at the two opposite lateral edges of the receiving recess for partially clamping the post of the vertical support therebetween; and a portion of the post being located outside the receiving recess and exposed from the two protruded blocks being smaller than a half circle. 
     
     
         3 . The sectional rack as claimed in  claim 2 , wherein the clamping members are formed by bending a metal plate, and the protruded blocks are formed by molding a plastic material. 
     
     
         4 . The sectional rack as claimed in  claim 2 , wherein a distance between the two protruded blocks on each of the clamping members is slightly smaller than an outer diameter of the posts of the vertical supports, so that the post is forced through the two protruded blocks and clamped in the receiving recess. 
     
     
         5 . The sectional rack as claimed in  claim 1 , wherein each of the clamping members is provided on a wall of the receiving recess near an upper end thereof with an inward protrusion extended into the receiving recess, and each of the posts of the vertical supports to be clamped in the receiving recesses is correspondingly provided with a recess for engaging with the protrusion, so that the clamping member is held in place on the post through engagement of the protrusion with the recess. 
     
     
         6 . The sectional rack as claimed in  claim 5 , wherein the wall of the receiving recess is an arc-shaped wall, and the protrusion extended from the wall of the receiving recess has a flat front end. 
     
     
         7 . The sectional rack as claimed in  claim 6 , wherein the wall of the receiving recess of the clamping member is provided with a through hole, which is located immediately below the protrusion. 
     
     
         8 . The sectional rack as claimed in  claim 1 , wherein the connecting members connected to between the two laterally juxtaposed posts of each of the vertical supports are respectively in the form of a vertically extended flat plate. 
     
     
         9 . The sectional rack as claimed in  claim 8 , wherein each of the clamping members is provided at a lower edge with a notch for engaging with an upper end of one flat-plate connecting member located between the two laterally juxtaposed posts. 
     
     
         10 . The sectional rack as claimed in  claim 1 , wherein the connecting members connected to between the two laterally juxtaposed posts of each of the vertical supports are respectively in the form of a round bar, and the round bars being horizontally extended between each pair of a front and a rear vertical support with front ends and rear ends of the round bars connected to the front and the rear vertical support, respectively.
