For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings. Specific language will be used to describe same. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates.
With reference to the drawings and in particular to FIGS. 1, 6A, 6B, 6C and 7, the open-end fastener for electrical wires according to the present invention basically comprises a clip 3, a nail 2 and a plastic cap 3. The plastic cap 3 is formed with a slot 33 horizontally extending therein, a vertical through hole 31 at the central portion and a circular recess 32 at the top and concentric with and having a larger diameter than the hole 31. The clip 3 has an end fitted into the horizontal slot 33 of the plastic cap 3, while the nail 2 has a pointed pin 21 adapted to be inserted through the center hole 31 and a flat head 22 adapted to be received in the circular recess 32.
Referring to FIGS. 2A, 2B, 2C, 3 and 4, the clip 1 is an integral wire member bent to form an upper front portion 111, a lower front portion 112, an upper intermediate portion 121, a lower intermediate portion 122, an upper rear portion 131 and a lower rear portion 132. Between the upper and lower intermediate portions 121 and 122 there is a space 12. Between the upper front portion 111 and the lower front portion 112 there is an entrance 11. Hence, the electrical wires 41 can be forced through the entrance 11 into the space 12 and kept in place by the restoring force of the upper front portion 111 .
As shown in FIGS. 5, 5A and 5B, the upper rear portion 131 and the lower rear portion 132 are connected to each other and there are a first area 133 and a second area 134 at the rear portion of the clip 1. The first area 133 is designed for the passage of the pointed pin 21 of the nail 2, while the second area 134 is to be pressed against by the flat head 22 of the nail 2, so that the clip 1 can be firmly fastened on the wall.
As the fastener according to the present invention is has an open-end clip 1, so that even the electrical wires 41 kept in position by the open-end fasteners ~see FIGS. 8, 8A and 8~) are inadvertently pulled out of the fasteners, the fasteners will remain on the wall and the electrical wires 41 can be easily forced through the entrance 11 into the space 12 of the clip 1 thereby keeping the electrical wires 41 in position again. In addition, the open-end clip 1 can be used as a suspension hook, as shown in FIG. 9 and 9A.
FIGS. 10 and lOA illustrate a second preferred embodiment of the present invention. As shown, the lower front portion 112' is connected with the lower intermediate portion 122' on the same horizontal plane and the lower intermediate portion 122' is bent upwardly to form an upper intermediate portion 121' to form a space 12'. Hence, the nail 2' can go directly through the front end of the clip 1' to fix the clip 1' on the wall 5' and this embodiment does not need a plastic cap 2.
FIGS. 11, llA, 11~, 12, 13 and 14 illustrate a third preferred embodiment of the present invention. As shown, the plastic cap 3 is formed with a main groove 330 at the bottom, a vertical through hole 310 at the central portion, a circular recess 320 at the top and concentric with and having a larger diameter than the hole 310, and two opposite grooves 340 at two sides of the bottom extending inwardly to be in communication with the main groove 330. The clip 100 includes two legs 1120 each having a outwardly extending lug 1350 at the end so that when the clip 100 is engaged with plastic cap 3, the legs 1120 are fitted in the main groove 33 and their lugs 1350 engaged with the grooves 340 of the plastic cap 3.
Further, the clip 100 includes an upper portion 1110 which will provide a passage 110 for an electrical wire (not shown) to go into the space 120 between the upper U-shaped portion 1110 and the legs 1120.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the -details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
Regarding the conventional suspension hooks, they also suffer from the following disadvantages:
1. If the hook portion is of a large size~ it will be easily catch hold of something thus causing much inconvenience in use. If the hook portion is of a small size, it cannot be used for hanging heavy objects.
2. The hook portion is open and so it cannot hold the object securely.
Therefore, it is an object of the present invention to provide an improved fastener which can obviate and mitigate the above-mentioned drawbacks.
