Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a fastener.

2. Description of the Related Art

Referring to FIGS. 10 and 11, a conventional fastener 1 is mounted on a support member 3 and adapted to pivotally couple to a rack 2. A projection 4 is formed on an end of the rack 2 and proximal to the support member 3. While an article is disposed on the rack 2, the rack 2 is driven to pivot slightly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 through 6, a fastener 10 in accordance with the preferred embodiment in the present invention includes a body member 20, a joint member 30 and a fixing member 40. The body member 20 is able to be mounted on the support 50 slideably. The joint member 30 is sandwiched in the body member 20. An end of the joint member 30 extends from the body member 20 and is coupled to one rack 60. The fixing member 40 is used to selectively lock the joint member 30 in the body member 20. After combining several fasteners 10 to the support 50 and adjusting positions of the fasteners 10 on the support 50, as shown in FIG. 2, the racks 60 which are respectively coupled to the joint members 30 are able to hang kayaks, Surfboards or the like thereon.

The body member 20 consists of a first coupled element 201 and a second coupled element 202, and the first and second coupled elements 201, 202 engage with each other via two pivotal ears 203 formed on sides of the first and second coupled elements 201, 202 and a pivotal pin 204. The pivotal ears 203 of the first and second coupled elements 201, 202 are wedged with each other, and the pivotal pin 204 is inserted through the pivotal ears 203 for attaching the first and second coupled elements 201, 202 to each other. Thus, the first and second coupled elements 201, 202 are able to pivot relative to each other with respect to the pivotal pin 204.

The assembled body member 20 includes a receiving portion 21 longitudinally formed therein and proximal to the pivotal ears 203. Two clamping portions 22 are respectively defined on the first and second coupled elements 201, 202 transversely extending from the receiving portion 21 and parallel to each other and an open space 23 defined between the clamping portions 22. The receiving portion 21 is mounted on the support 50. A gap 24 is formed on the sidewall of the receiving portion 21 and communicates the space 23 with the receiving portion 21. A pivotal portion 25 provided in the space 23 are formed by the first and second coupled elements 201, 202 and provided to transversely pierce through and interconnect the clamping portions 22. A receptacle 26 is formed on the outer periphery of each clamping portion 22 and opened to the distal of the related one of the first and second coupled elements 201, 202. A direction of each receptacle 26 is perpendicular to that of the receiving portion 21. A through-hole 27 is provided in the receptacle 26 of each clamping portion 22 and communicates with the space 23. Horizontal positions of the gap 24, the pivotal portion 25 and the receptacles 26 are the same approximately.

A channel 251 is formed through the pivotal portion 25 and pierces the clamping portions 22. Two non-circular holes 252 are respectively formed on the outer periphery of the clamping portions 22 and integrated to two ends of the channel 251.

The joint member 30 is coupled to the pivotal portion 25 in a pivotal manner and defines a first end 301 opposite to the body member 20 and a second end 302 pivotally coupled to the body member 20. A pivoting hole 31 and a fixed hole 32 are respectively provided through the second end 302 transversely and correspond to the pivotal portion 25 and the through-holes 27.

A bolt 253 and a nut 254 are adapted to couple the first and second coupled elements 201, 202 and the second end 302 of the joint member 30 to one another by inserting the bolt 253 through the channel 251 from one of the non-circular holes 252, through the pivoting hole 31 to the other non-circular hole 252 and engaging the bolt 253 with the nut 254. The nut 254 is embedded in the related non-circular hole without protruding therefrom. In this case, each non-circular hole is preferably a hexagonal hole, and nut 254 is preferably a hexagonal nut. Further, it is easy to disengage the bolt 253 from the nut 254 so that it is quick and easy to detach the first and second coupled elements 201, 202 from each other for changing position of the body member 20 on the support 50.

A joint sheath 33 is provided at the first end 301 of the joint member 30 and opened opposite to the second end 302. One rack 60 is inserted into the joint sheath 33. A hook portion 34 is integrally formed on the top side of the first end 301 of the joint member 30 and adapted to clamp the support 50 selectively. A cam portion 35 and a guiding portion 36 are defined on the distal portion of the second end 302.

The joint member 30 is moveable between an unfolding position and a folding position. While the rack 60 is coupled to the joint member 30 for hanging articles (kayaks, surfboards or the like), the weight of the rack 60 enables the joint member 30 to pivot with respect to the support 50 to the unfolding position. A downward pivoting angle of the joint member 30 with respect to the support 50 is restricted by the cam portion 35 which is selectively abutted against the support 50 through the gap 24. Also, during pivoting of the joint member 30 with respect to the support 50, the guiding portion 36 is not in contact to the support 50. While the rack 60 collapsing with respect to the support 50, the joint member 30 is pivoted toward the support 50, and the cam portion 35 is disengaged from the support 50. Then, the hook portion 34 clamps the support 50 for fixing the joint member 30 and the rack 60 to the support 50. Further, it can save area and space for storing the rack 60 and the support 50.

A fixing member 40 is installed to the outer periphery of the clamping portions 22 and adapted to selectively fix the joint member 30 with respect to the body member 20. The fixing member 40 includes two fixing elements 41 and two elastic elements 42. The fixing elements 41 respectively fit in the receptacles 26, and the elastic elements 42 are respectively sandwiched between the fixing elements 41 and the receptacles 26. Each fixing element 41, which has a first end and a second end proximal to the receiving portion 21 includes a pressing portion 411 on the outer periphery of the first end thereof. An engaged portion 412 on the interior periphery of the second end of each fixing element 41 is selectively inserted into the through-hole 27 of the related receptacle 26. Two pivotal ears 413 are provided on each fixing element 41 and abutted with the inner wall of the related receptacle 26. A pivotal pin 414 is inserted through the pivotal ears 413 of each fixing element 41 and two apertures 261 of the related receptacle 26 as to pivotally couple each fixing element 41 to the related receptacle 26.

While the fixing elements 41 are in an idle position, the elastic elements 42 push the first end of the fixing elements 41 outwardly so that the engaged portions 412 pivot inwardly while inserted into the through-holes 27 and the fixed holes 32 for restricting the joint member 30 to pivot with respect to the body member 20. While pressing the pressing portions 411 inwardly and while the fixing elements 41 are in an operative position, the engaged portions 412 pivot outwardly to disengage from the through-holes 27 and the fixed holes 32 so that the joint member 30 is able to pivot with respect to the body member 20 (shown in FIGS. 7 through 9).

While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
