Connector for shelf assembly

Abstract

A connector for shelf assembly may comprise at least a connector having a semi-cylindrical concave formed at a lateral edge thereof, and a first hook portion and a second hook portion respectively protrude from two lateral ends of the inner edge of the concave. When the connector is applied to a shelf, the first hook portion and the second hook portion thereof are configured to respectively hook on two adjacent edges of a shelf board of the shelf which are perpendicular to each other. Each of the connectors can be directly coupled with a collar of the shelf board such that an external board can be assembled between the two shelves without dissembling process. Also, the external board can be assembled parallel with the shelf boards on the two shelves, which improves the practicability and stability of the assembled shelves with the external board when in use.

DETAILED DESCRIPTION OF THE INVENTION

(12) The detailed description set forth below is intended as a description of the presently exemplary device provided in accordance with aspects of the present invention and is not intended to represent the only forms in which the present invention may be prepared or utilized. It is to be understood, rather, that the same or equivalent functions and components may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention.

(13) Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. Although any methods, devices and materials similar or equivalent to those described can be used in the practice or testing of the invention, the exemplary methods, devices and materials are now described.

(14) All publications mentioned are incorporated by reference for the purpose of describing and disclosing, for example, the designs and methodologies that are described in the publications that might be used in connection with the presently described invention. The publications listed or discussed above, below and throughout the text are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the inventors are not entitled to antedate such disclosure by virtue of prior invention.

(15) In order to further understand the goal, characteristics and effect of the present invention, a number of embodiments along with the drawings are illustrated as following:

(16) Referring to FIGS. 1 and 2, the present invention provides a connector for shelf assembly which comprises at least a connector (10). The connector (10) has a semi-cylindrical concave (11) formed at a lateral edge thereof, and an inner edge of the concave (11) comprises a protruding portion (111). A first hook portion (12) and a second hook portion (13) respectively protrude from two lateral ends of the inner edge of the concave (11), and ends of the two hook portions (12)(13) are faced downwardly. An included angle between an axial central line of the concave (11) to the first hook portion (12) and the second hook portion (13) is 90 degree such that when the connector (10) is applied to a shelf assembly, the first hook portion (12) and the second hook portion (13) thereof are configured to respectively hook on two adjacent edges of the shelf assembly which are perpendicular to each other. The inner surface of the concave (11) is formed into an attaching surface (14), and an arc-shaped first connecting member (15) protrudes from the other lateral edge of the connector (10) located opposite to the concave (11). Moreover, an engaging portion (16) is integrally formed at an outer surface of the first connecting member (15).

(17) In actual application, referring to FIGS. 3 and 4, the four connectors (10) as two pairs are respectively assembled on two shelves (20) symmetrically, and at least an external board (30) is assembled between the two shelves (20) through the connectors (10), wherein each of the two shelves (20) comprises four vertical poles (21) and a plurality of shelf boards (22) assembled therebetween, and each of the poles (21) has a plurality of peripheral grooves sequentially formed at an outer surface thereof. Moreover, each of the shelf boards (22) is a square board having two pairs of parallel side bars, which are two first side bars (221) positioned along a front-back direction and two second side bars (222) positioned along a lateral direction, and each of four corners of the single shelf board (22) comprises a collar (223) to enable the shelf board (22) to be assembled between the four vertical poles (21).

(18) Referring to FIGS. 4 and 5, the connector (10) is configured to couple with the collar (223) of the shelf board (22) through the concave (11) thereof, and the first hook portion (12) and the second hook portion (13) are provided to respectively hook on the first side bar (221) and the second side bar (222) at two sides of the collar (223). Also, the protruding portion (111) of the concave (11) is abutted against an upper edge of the collar (223), and the first connecting member (15) of the connector (10) is faced outwardly. Thus, two adjacent outer edges respectively on the two shelves (20) have two pairs of the connectors (10) face to face which are configured to cooperate with each other to assemble one external board (30) therebetween.

(19) Referring to FIGS. 4 to 8, each of four corners of the external board (30) has a concaved second connecting member (31) which is faced outwardly and configured to engage with the first connecting member (15) of the connector (10). Moreover, a lower end of the second connecting member (31) comprises two vertical engaging notches (311) to form an engaging block (312) therebetween, wherein the engaging block (312) is adapted to engage with the engaging portion (16) of the first connecting member (15), thereby firmly assembling the external board (30) between the two shelves (20).

(20) Comparing with conventional connector of shelf assembly, the present invention is advantageous because: (i) the connectors (10) can be directly assembled on the collars (223) of the shelf boards (22) on the two shelves (20) respectively, and the external board (30) can be directly assembled between the two shelves (30) without disassembling process; and (ii) the external board (30) can be assembled parallel with the shelf boards (22) on the two shelves (20), which improves the practicability and stability of the assembled shelves (20) with the external board (30) when in use.

(21) Furthermore, referring to FIGS. 8 and 9, the connector (10) has a hollow cushion member (17) formed between the attaching surface (14) and the first connecting member (15), which can effectively prevent the connector (10) from getting stuck on the collar (223) of the shelf board (22) when disassembling process and also can enable the attaching surface (14) to be pressed inwardly thereby applied to a larger or longer collar (223).

(22) Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalents.
