DETAILED DESCRIPTION OF THE INVENTION
The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
FIGS. 1A and 1B show a satellite antenna of a first embodiment of the invention, including a connection rod (first member of the first embodiment) 10, a receiver (second member of the first embodiment) 20 and a connecting unit 100. First openings 11 are formed on the connection rod 10. Second openings 21 are formed on the receiver 20. The connecting unit 100 fixes the connection rod 10 to the receiver 20. The connecting unit 100 comprises a connection post 110, an abutting element 120 and a rotatable stopper 130. The connection post 110 comprises a first end 111 and a second end 112. The abutting element 120 pivots on the first end 111 of the connection post 110. The rotatable stopper 130 pivots on the second end 112 of the connection post 110. In a fixing state (FIG. 1A), the connection post 110 passes through the first openings 11 and the second openings 21. The abutting element 120 pulls the rotatable stopper 130 to tightly abut a first surface 12 of the connection rod 10, and the connection rod 10 is fixed to the receiver 20. In the embodiment above, the rotatable stopper 130 is manually rotated by the user to abut the first surface 12.
With reference to FIGS. 1A and 1B, the abutting element 120 pivots between an abutting orientation (FIG. 1A) and a releasing orientation (FIG. 1B), the abutting element 120 comprises a cam portion 121 and a wrench portion 122. With reference to FIG. 1B, the extending direction X of the cam portion 121 is perpendicular to the extending direction Y of the wrench portion 122. With reference to FIG. 1A, in the fixing state, the abutting element 120 is in the abutting orientation, and the cam portion 121 abuts a second surface 13 of the connection rod 10. The first surface 12 is opposite the second surface 13. The cam portion 121 pushes the second surface 12 of the connection rod 10 to reduce a free space on the connection post 110 between the abutting element 120 and the rotatable stopper 130. The rotatable stopper 130 therefore tightly abuts the first surface 12 of the connection rod 10. The abutting element 120 pivots on the connection post 110 by bolts or other elements.
With reference to FIGS. 1A and 1B, the rotatable stopper 130 pivots between a first orientation (FIG. 1B) and a second orientation (FIG. 1A). When the rotatable stopper 130 is in the first orientation (FIG. 1B), the rotatable stopper 130 is adapted to pass through the first openings 11 and the second openings 21. When the rotatable stopper 130 is in the second orientation (FIG. 1A), the rotatable stopper 130 abuts the first surface 12 of the connection rod 10. In this embodiment, the first openings 11 and the second openings 21 are circular holes and the rotatable stopper 130 is a longitudinal structure. The second end 112 of the connection post 110 pivots on a center portion of the rotatable stopper 130. In an assembly state (FIG. 1B), the rotatable stopper 130 and the connection post 110 are located on the same straight line, and the rotatable stopper 130 passes through the first openings 11 and the second openings 21. In the fixing state (FIG. 1A), the rotatable stopper 130 and the connection post 110 form a T-shaped structure.
In the embodiment above, the rotatable stopper 130 can be a stamping part with a U-shaped cross section. The rotatable stopper 130 provides reliable fixing function with decreased dimension. Utilizing the first embodiment of the invention, the first member and the second member of the satellite antenna can be easily assembled or disassembled without any manual tools.
FIGS. 2A and 2B show a satellite antenna of a second embodiment of the invention, including a satellite dish (first member of the second embodiment) 30, a supporting frame (second member of the second embodiment) 40 and the connecting unit 100′. A first opening 31 is formed on the satellite dish 30 (with reference to FIG. 3A). A second opening 41 is formed on the supporting frame 40. The connecting unit 100′ fixes the satellite dish 30 to the supporting frame 40. The connecting unit 100′ comprises a connection post 110, an abutting element 120 and a rotatable stopper 130′. The connection post 110 comprises a first end 111 and a second end 112. The abutting element 120 pivots on the first end 111 of the connection post 110. The rotatable stopper 130′ pivots on the second end 112 of the connection post 110. In a fixing state (FIG. 2A), the connection post 110 passes through the first opening 31 and the second opening 41. The abutting element 120 pulls the rotatable stopper 130′ to tightly abut a first surface 32 of the satellite dish 30. In the fixing state (FIG. 2A), the cam portion 121 of the abutting element 120 abuts a third surface 42 of the supporting frame 40, and the first surface 32 is opposite the third surface 42.
With reference to FIG. 2C, in the second embodiment, the rotatable stopper 130′ comprises a circular plate 131 and a pivot portion 132. The pivot portion 132 is disposed on the circular plate 131, and the second end 112 of the connection post 110 is connected to the pivot portion 132. In this embodiment, the second opening 41 comprises a slot area 43 and an opening area 44, and the slot area 43 is connected to the opening area 44. In an assembly state (FIG. 2B), the circular plate 131 is parallel to the connection post 110, the circular plate 131 passes through the slot area 43, and the pivot portion 132 passes through the opening area 44.
With reference to FIG. 2C, in the fixing state, the pivot portion 132 is located in the opening area 44, and the circular plate 131 is perpendicular to the connection post 110.
With reference to FIGS. 3A-3D, in one embodiment, the first opening 31 is formed in a circular recess 33, and the circular recess 33 is formed on the first surface 32 (in this embodiment, the first surface 32 is the reflective surface of the satellite dish). In the assembly process, the circular plate 131 passes through the first opening 31 (FIG. 3B) first. Then, the circular plate 131 is rotated to be perpendicular to the connection post 110 (FIG. 3C). Finally, the abutting element 120 is twisted into the fixing state (FIG. 3D). In the fixing state, the circular plate 131 is located in the circular recess 33 to cover the first opening 31 to improve the appearance and integrity of the satellite antenna, which maintains the reflective effect of the satellite dish. In one embodiment, the circular plate 131 can sufficiently cover the circular recess 33.
Utilizing the second embodiment of the invention, the first member and the second member of the satellite antenna can be easily assembled or disassembled without any manual tools. Additionally, the appearance of the satellite antenna and the reflective effect of the satellite dish are improved. Utilizing the embodiments of the invention, the number of bolts of the satellite antenna is decreased, and the problem of the bolt thread damage is reduced.
Use of ordinal terms such as “first”, “second”, “third”, etc., in the claims to modify a claim element does not by itself connote any priority, precedence, or order of one claim element over another or the temporal order in which acts of a method are performed, but are used merely as labels to distinguish one claim element having a certain name from another element having the same name (but for use of the ordinal term).
While the invention has been described by way of example and in terms of the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. On the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
