Description
- 1. Field of the Invention
- The invention relates to a leg assembly, more particularly to a modular leg assembly for a canopy.
- 2. Description of the Related Art
- Referring to FIGS. 1 and 2, a
conventional leg assembly 1 for a canopy is shown to comprise amulti-way connector 11 disposed on top of theleg assembly 1, a plurality ofcurved support rods 12 connected to themulti-way connector 11, a plurality of four-way connectors 13, each of which is connected to a lower end of a respective one of thesupport rods 12, a plurality of horizontal linkingrods 14, each of which is connected between an adjacent pair of the four-way connectors 13, a plurality of hollowupright leg members 15, each of which is connected pivotally to a lower end portion of a respective one of the four-way connectors 13, and a plurality ofleg seats 16, each of which is connected fixedly to a lower end of a respective one of theleg members 15. - Referring to FIG. 2, in each junction of the four-
way connector 13 and theleg member 15, there is provided aninterlocking device 17 so as to stabilize connections among theconnectors support rods 12, the linkingrods 14, and theleg members 15. Since theinterlocking devices 17 are substantially similar in construction, only oneinterlocking device 17 will be described hereinafter. Theinterlocking device 17 includes an L-shaped retaining groove 171 formed in anextended section 131 of the four-way connector 13, and anengaging pin 172 that extends inwardly and radially from an inner surface of theleg member 15. Theretaining groove 171 has anaxial hole section 173 and atransverse hole section 174 that is transverse to theaxial hole section 173. During assembly, theextended section 131 of the four-way connector 13 is sleeved into theleg member 15 in such a manner that theaxial hole section 173 of thegroove 171 can receive theengaging pin 172 of theleg member 15, after which theleg member 15 is rotated so that theengaging pin 172 engages thetransverse hole section 174 of thegroove 171 in the four-way connector 13 so as to prevent removal of theleg member 15 from the four-way connector 13. - Although the design of the
conventional leg assembly 1 can achieve its intended purpose, however, in actual use, theleg members 15 cannot support stably the remaining elements of theleg assembly 1 since theleg members 15 are relatively thin. Furthermore, the number of theleg members 15 in theleg assembly 1 is relatively large such that a passage between each adjacent pair of theleg members 15 is relatively narrow, thereby inconveniencing the users. Moreover, the configuration of eachinterlocking device 17 can complicate and slow down the assembly process of theleg assembly 1. In addition, the interlockingdevices 17 are difficult to assemble due to the structure of the curvedupper support rods 12. - Therefore, the object of the present invention is to provide a modular leg assembly that is capable of overcoming the aforementioned drawbacks of the prior art.
- According to the present invention, a modular leg assembly comprises at least three upright support members, an annular link frame, and a top support frame. Each of the upright support members includes an adjacent pair of planar first and second leg frames that are connected detachably to each other and that are adapted to stand on a ground surface. Each of the first and second leg frames includes a vertical engaging side and a vertical non-engaging side opposite to the vertical engaging side. During assembly, the vertical engaging sides of the first and second leg frames of each of the support members are close to and are connected detachably to each other, and the vertical non-engaging sides of the first and second leg frames of each of the support members are spaced apart from each other. The link frame is mounted on a top end of each of the support members, and includes a plurality of corner connectors, each of which is connected detachably to a respective one of the support members, a plurality of horizontally-extending link members, each of which is connected telescopically to an adjacent pair of the corner connectors, and a plurality of first positioning units for positioning each of the link members between the adjacent pair of the corner connectors. A top support frame is mounted detachably on the link frame, and includes a central connector, a plurality of main support rod members, each of which is connected telescopically to the central connector and a respective one of the corner connectors, a plurality of second positioning units for positioning the central connector relative to the main support rod members, and a plurality of third positioning units for positioning the main support rod members relative to the corner connectors.

Then, thesecond leg frame 22 of eachsupport member 2 is removed from thefirst leg frame 21 of thecorresponding support member 2, thereby completely disassembling themodular leg assembly 100 for storage. - The structural design of the
modular leg assembly 100 of the present invention is not limited to include fourupright support members 2. The modular leg assembly can be modified to include only threeupright support members 2 without affecting the ability to support the canopy thereon. - From the above description of the preferred embodiment of the
modular leg assembly 100 of the present invention, it is apparent that themodular leg assembly 100 can support the canopy more stably due to the configuration of theupright support members 2. Furthermore, the distance betweenadjacent support members 2 can be increased so as to facilitate passage therethrough. Moreover, assembly and disassembly of the present invention only involve insertion and pushing of the retaining blocks of the positioning units so as to engage and separate members of themodular leg assembly 100, which is more simpler as compared to theconventional leg assembly 1. - While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
