Description
- The present invention relates to a collapsible rack.
- A typical collapsible rack includes inserts and sleeves for receiving the inserts. It is however troublesome and takes a lot of time to insert the inserts into the sleeves during assembly of the collapsible rack. It requires tools to assemble the collapsible rack, and the assembly is complicated. Furthermore, the result of the collapse is inadequate so that the collapsible rack takes a lot of space in a collapsed position during storage and transportation.
- The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.
- It is an objective of the present invention to provide a collapsible rack that can easily be assembled.
- It is another objective of the present invention to provide a collapsible rack that occupies a little space in a collapsed position.
- To achieve the foregoing objectives, the collapsible rack includes a middle frame, a first lateral frame pivotally connected to the middle frame, a second lateral frame pivotally connected to the middle frame and at least one shelf pivotally connected to the middle frame. The middle frame includes a first pair of ears formed thereon and a second pair of ears formed thereon. The first lateral frame includes a pair of screws driven through the first pair of ears, thus pivotally connecting the first lateral frame to the middle frame. The second lateral frame includes a pair of screws driven through the second pair of ears, thus pivotally connecting the second lateral frame to the middle frame. The shelf includes a first edge pivotally connected to the middle frame and a second edge for engagement with the first and second lateral frames when the collapsible rack is in an extended position.
- Other objectives, advantages and features of the present invention will become apparent from the following description referring to the attached drawings.
- The present invention will be described via detailed illustration of the preferred embodiment referring to the drawings.
-
FIG. 1 is a perspective view of a collapsible rack according to the preferred embodiment of the present invention. -
FIG. 2 is a partial, enlarged view of the collapsible rack ofFIG. 1 . -
FIG. 3 is a perspective view of the collapsible rack in another position than shown inFIG. 1 . -
FIG. 4 is a partial, enlarged view of the collapsible rack ofFIG. 3 . -
FIG. 5 is a perspective view of the collapsible rack in another position than shown inFIG. 3 . -
FIG. 6 is a partial, enlarged view of the collapsible rack ofFIG. 5 . -
FIG. 7 is a perspective view of the collapsible rack in another position than shown inFIG. 5 . - Referring to
FIGS. 1 and 2 , a collapsible rack includes amiddle frame 1, a firstlateral frame 2 pivotally connected to themiddle frame 1, a secondlateral frame 3 pivotally connected to themiddle frame 1, alower shelf 4 pivotally connected to themiddle frame 1, amiddle shelf 4 pivotally connected to themiddle frame 1 and anupper shelf 11 pivotally connected to themiddle frame 1 according to the preferred embodiment of the present invention. Themiddle frame 1 includes twobeams 15 provided between twoposts 18. Twoears 5A are formed on one of theposts 18 while twoears 5B are formed on theother post 18. Each of theears aperture 6 defined therein. - The second
lateral frame 3 includes twobeams 24 connected to apost 26. Ascrew 7 is secured to each of thebeams 24. Tworings 9 are secured to thepost 26 while aslot 13 is defined in thepost 26. Thescrews 7 are driven through theapertures 6 of theears 5B and engaged withnuts 8, thus pivotally connecting the secondlateral frame 3 to themiddle frame 1. - The first
lateral frame 2 includes twobeams 20 connected to apost 22. Like each of thebeams 24, each of thebeams 20 includes ascrew 7 secured thereto. Tworings 9 are secured to thepost 22 while aslot 13 is defined in thepost 22. Thescrews 7 are driven through theapertures 6 of theears 5A and engaged withnuts 8, thus pivotally connecting the firstlateral frame 2 to themiddle frame 1. - Referring to
FIG. 3 , the length H1 of theears 5A is smaller than the length H2 of theears 5B. Thus, the firstlateral frame 2 is located between themiddle frame 1 and the secondlateral frame 3 when the collapsible rack is in a collapsed position. Thebeams 20 of the firstlateral frame 2 are longer than thebeams 24 of the secondlateral frame 3. Thus, the distance between themiddle frame 1 and thepost 22 of the firstlateral frame 2 is identical to the distance between themiddle frame 1 and thepost 26 of the secondlateral frame 3 when the collapsible rack is in an extended position. - Each of the lower and
middle shelves 4 is a grid with asleeve 16 formed along an edge, anaxle 17 extended through thesleeve 16 and twopins 10 formed at an opposite edge. Theupper shelf 11 is a grid with asleeve 16 formed along an edge, anaxle 17 extended through thesleeve 16 and twohooks 12 formed at an opposite edge. Each of theaxles 17 includes two ends each inserted in arecess 14 defined in a related one of theposts 18 of themiddle frame 1, thus pivotally connecting theshelves middle frame 1. - The
upper shelf 11 can be pivoted between a collapsed position shown inFIG. 1 and an extended position shown inFIG. 7 through a transient position shown inFIG. 3 . Referring toFIG. 4 , thehooks 12 can be inserted through theslots 13, thus retaining theupper shelf 11 in the extended position. In the extended position, theupper shelf 11 can support stuff. - The lower and
middle shelves 4 can be pivoted between a collapsed position shown inFIG. 1 and an extended position shown inFIG. 7 through a transient position shown inFIG. 5 . Referring toFIG. 6 , thepins 10 can be inserted through therings 9, thus retaining the lower andmiddle shelves 4 in the extended position. In the extended position, the lower andmiddle shelves 4 can support stuff. - The present invention has been described via the detailed illustration of the preferred embodiment. Those skilled in the art can derive variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention defined in the claims.
