STRUCTURE OF COUPLING SLEEVE OF STORAGE SHELF
A storage shelf coupling sleeves each having symmetrically arranged engagement slots formed thereon to be convergent, through sloping, in a downward direction. The coupling sleeves are respectively mounted to fixed rods. A support frame has retention plates respectively fit to the coupling sleeves by being received in one of the engagement slots of each coupling sleeve. Another engagement slot of each of the coupling sleeves may receive a retention plate of another support frame to fit therein so that a number of support frames can be connected in a side-by-side manner thereby making assembly and expansion of the storage shelf easy and the expanded arrangement tidy and organized. The coupling sleeve is of a hollow cylindrical configuration. The support frame has corners each comprising one retention plate attached thereto. The retention plate is made convergent, through sloping, in the downward direction to facilitate fitting thereof into the coupling sleeve.
The present invention generally relates to an improved structure of a cooping shelf of a storage shelf, and more particularly to an improved structure of a coupling sleeve of a storage shelf that allows for easy assembling and expansion through side-by-side arrangement and provides a tidy configuration.
DESCRIPTION OF THE PRIOR ARTA conventional knockdown storage shelf generally has a structure that is assembled as illustrated in
The primary object of the present invention is to provide an improved structure of a coupling sleeve of a storage shelf that allows for easy assembling and expansion through side-by-side arrangement and provides a tidy configuration.
The improved structure of storage shelf according to the present invention comprises coupling sleeves and a support frame. The coupling sleeve has an outer surface on which symmetrically arranged engagement slots are formed in such a way that the engagement slots are convergent, through sloping, in a downward direction. A number of coupling sleeves are respectively mounted to fixed rods and the support frame is positioned to have the retention plates thereof respectively fit to the coupling sleeves by being received in one of the engagement slots of each coupling sleeve thereby forming one unit of storage shelf Another engagement slot of each of the coupling sleeves may receive a retention plate of another support frame to fit therein so that a number of support frames can be connected in a side-by-side manner thereby making assembly and expansion of the storage shelf easy and the expanded arrangement tidy and organized. The coupling sleeve is of a hollow cylindrical configuration. The engagement slots are each formed by first stamping a portion of a circumferential wall of the coupling sleeve to form an opening so as to form an L-shaped suspending tab. The support frame has corners each comprising one retention plate attached thereto. The retention plate is of a circular curved configuration and is made convergent, through sloping, in the downward direction to facilitate fitting thereof into the coupling sleeve.
In the improved structure of storage shelf described above, the L-shaped suspending tabs formed on the circumferential wall of the coupling sleeve are arranged to face opposite directions.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
Referring to
With the components described above, a number of coupling sleeves 4 are provided and each is fit to one of fixed rods of a storage shelf the fixed rods in such a way that the support frame 5 is positioned to have the retention plates 51 thereof respectively fit into the first engagement slots 41 of the coupling sleeves 4 with the hooks 52 supported on top edges of the suspending tabs 44 to thereby couple and fix the support frame 5 to four fixed rods 4, and complete one unit of storage shelf The second engagement slots 42 can be used to receive the retention plates 51 of another support frame 5 to fit therein. As such, a number of support frames 5 can be connected together in a side-by-side manner. The assembly of the storage shelf easy and efficient (for it can be easily kept balanced to allow the assembly to be carried out by a single person) and allows for multiple storage shelves to be connected in a side-by-side manner for expansion and the expanded arrangement is made tidy and organized.

Claims
1-3. (canceled)
4: A storage shelf structure, comprising a plurality of coupling sleeves and a support frame, the coupling sleeves being each of a hollow cylindrical configuration having an outer surface on which at least one pair of symmetrically arranged first engagement slots and second engagement slots are formed, the support frame having four corners each of which comprises a retention plate mounted thereto, the plurality of coupling sleeves being respectively fit to fixed rods to allow the support frame to be positioned in such a way that the retention plates are respectively fit into the first engagement slots of the coupling sleeves to fix the support frame to the fixed rods thereby forming a single unit of storage shelf, the second engagement slots receiving retention plates of an additional support frame to fit therein, whereby a number of support frames are connectable in a side-by-side manner, characterized in that: the first engagement slots and the second engagement slots of each of the coupling sleeves are each formed by first stamping a circumferential wall of the coupling sleeve to form an opening in the form of being convergent, through sloping, in a downward direction and bending a separated portion that is stamped off the circumferential wall to form an L-shaped suspending tab, wherein two L-shaped suspending tabs so formed face in opposite direction.
5: The storage shelf structure according to claim 4, wherein the first engagement slots and the second engagement slots of the coupling sleeve are each in the form of being convergent, through sloping, in a downward direction.
6: The storage shelf structure according to claim 4, wherein the retention plates of the support frame each comprise two hooks formed on and extending horizontally from upper ends of opposite side edges thereof so that when the retention plate of the support frame is fit into an engagement slot of the coupling sleeve, the hooks engage and are supported on top edges of the suspending tabs.
