Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a fastening apparatus for a car multimedia player and particularly to a fastening apparatus to facilitate rapid installation and removal of a car multimedia player.

2. Description of the Prior Art

The holding dock for a car multimedia player now is available on some new cars. For the earlier cars that do not have the holding dock, there is no holding structure to allow the multimedia player to be easily installed or removed. Referring to FIG. 11, the conventional approach is to hold a multimedia player A1 on a dock fastened to the central control board B1 of the car (close to the windshield). It cannot be removed readily. As a result, when the driver leaves the car, the multimedia player could be stolen easily. Moreover, when projected by sunlight and subject to high temperature, the life span of the multimedia player shortened. When not in use, users also have to cover the multimedia player with a proper means to fend off dusts.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a fastening apparatus to facilitate installation and removal of a car multimedia player so that users can install the multimedia player quickly when needed and remove the multimedia player easily when not in use, and also guard against theft and dust pollution.

In one aspect, the invention includes a first fastening member fastening to an anchor seat. The first fastening member has a strut and a wing flap extended sideward from the top end of the strut. A second fastening member is located on the bottom of the car multimedia player and has a coupling bore to couple with the first fastening member. The structure thus formed can overcome the problems occurred to the conventional techniques.

The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 and 2, the present invention mainly includes:

a first fastening member 3 which is fastened to an anchor seat 1, and has a strut 31, and a wing flap 312 extended sideward from the top end of the strut 31; and

a second fastening member 41 located on the bottom of a body 40 of a car multimedia player 4, and has a coupling bore 411 to couple with the strut 31 of the first fastening member 3.

The anchor seat 1 has a body 10 which has a plurality of fastening holes 101 and a plurality of slots 102 spaced from one another to allow the body 10 to form a plurality of radial blades 103 on the periphery.

The first fastening member 3 has a body 30 with the strut 31 located thereon. The body 30 is circular, and has a center portion 300 with a two-step screw hole 301 formed thereon. It also has one or more magnet holding troughs 302 and 305 to hold one or more magnets 303 and 306. It has an annular ring 304 formed on the perimeter that has an elevation higher than the center portion 300 but lower than the strut 31.

The strut 31 has a stem 310 which has a screw hole 311 formed thereon. The wing flap 312 is extended sideward from the top end. The body 30 is fastened to the anchor seat 1 through a fastening element 313.

The second fastening member 41 is located on the bottom of the body 40 of the car multimedia player 4 and has an area corresponding to the first fastening member 3. The area is made of metal which may be attracted by the magnets 303 and 306. The coupling bore 411 corresponds to the strut 31. It has a first width D1 to accommodate the stem 310 of the strut 31 and a second width D2 to accommodate the wing flap 312 so that after the wing flap 312 has been aligned with the second width D2, the strut 31 may be inserted into the coupling bore 411. Then the car multimedia player 4 may be turned to allow the wing flap 312 to be braced by the peripheral area of the coupling bore 411 on the second width D2 and confined without breaking away.

The second fastening member 41 further has two semi-circular extensions 412 and 413 corresponding to the second width D2 and being in the magnetic attraction area of the magnets 303 and 306. The semi-circular extensions 412 and 413 have a diameter slightly smaller than the inner diameter of the annular ring 304 so that they may be turned in the annular ring 304 without sliding outside to anchor the first fastening member 3 on the second fastening member 41.

The second fastening member 41 also has two notches 414 formed between the semi-circular extensions 412 and 413 corresponding to the first width D1 (about the front direction of the car multimedia player 4) in the form of a trumpet. The notch has a wider opening close to the edge of the semi-circular extensions 412 and 413 and is tapered gradually in the center until reaching the coupling bore 411 to facilitate mounting and positioning of the car multimedia player 4.

By means of the elements set forth above, the flexible blades 103 of the anchor seat 1 may be fastened to the center control board, center armrest or car top by a fastening element E1 (as shown in FIG. 2), or a bonding element E2 (as shown in FIGS. 3 and 4). The fastening element E1 may be a screw, rivet or the like. The bonding element E2 may be a double-side adhesive tape, adhesive, or the like. Then the car multimedia player 4 may be installed by coupling the coupling bore 411 of the second fastening member 41 with the strut 31 with the two semi-circular extensions 412 and 413 wedged in the annular ring 304, then turn the car multimedia player 4 for ninety degrees to make the wing flap 312 and the coupling bore 411 cross at ninety degrees to finish the installation of the car multimedia player 4 (referring to FIGS. 5 and 6). By contrast, to remove the car multimedia player 4, turn it in the reverse direction for ninety degrees to overlap the coupling bore 411 and the wing flap 312 in the same direction. The car multimedia player 4 may be detached without using any tool.

In addition, the periphery of the anchor seat 1 may be covered by a pliable protective member F made from a pliable material such as rubber and formed in a cushion pad or a guarding cover to buffer vibration and shaking while the car is running to protect the multimedia player 4.

To avoid turning of the car multimedia player A becomes a problem, a second embodiment is provided shown in FIGS. 7 and 8. A first fastening member 6 having a body 60 which has at least two struts 61 and 62 mating at least two coupling bores 711 and 714 formed on the second fastening member 71 of a body 70 of a car multimedia player 7. The car multimedia player 7 may be directly installed by coupling the coupling bores 711 and 714 with the struts 61 and 62. To increase the mounting steadiness, as the previous embodiment, the body 60 has one or more magnets 603 and 604 to attract the metallic semi-circular extensions 712 and 713 of the second fastening member 71. For removing, merely disengage the car multimedia player 7 from the struts 61 and 62. This embodiment is preferable for mounting onto the central control board or central armrest, but is less desirable for mounting to the car top.

Another approach to avoid the problem of turning of the car multimedia player A is a third embodiment shown in FIGS. 9 and 10. A first fastening member 92 has a body 921 which has one or more first sliding troughs 922 and 923 mating one or more second sliding troughs 931 and 932 formed on a second fastening member 93 of the body 91 of the car multimedia player 9. The second sliding troughs 931 and 932 may be directly coupled with the first sliding troughs 922 and 923 to mount the car multimedia player 9 on the body 921. To increase the mounting steadiness, as the previous embodiment, the body 91 has one or more magnets 924 and 925 to attract the metal portion of the second fastening member 93. For removing, merely disengage the car multimedia player 9 from the first sliding troughs 922 and 923 of the first fastening member 92.
