TRACKING ELEMENT PROTECTION DEVICE

Abstract

A tracking element protection device includes a first part, two clamp members and a second part. The first part includes a first recess, and the second part includes a second recess. A tracking element is received in the first recess. The first and second parts are connected to each other by two fasteners. The two clamp members are located between the first and second parts so as to clamp the protection device to a bicycle frame between the two clamp members. Each fastener includes a head and a threaded shank which extends through the second part and is threadedly connected a threaded hole in the first part. The head of each fastener includes three first positioning portions. A key is mounted to the head and includes three second positioning portions which are engaged with the first positioning portions to unscrew the fastener to separate the first and second parts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0022] Referring to FIGS. 1 and 2, the tracking element protection device 10 of the present invention comprises a first part 20, two clamp members 30, 301 and a second part 40. The first and second parts 20, 40 are connected with each other by two fasteners 50, and the two clamp members 30, 301 are located between the first and second parts 20, 40. Two ribs 23 respectively extend outward from two ends of the inside of the first part 20. Each rib 23 includes a threaded hole 25. A first recess 21 is defined in the inside of the first part 20 and a tracking element 60 is received in the first recess 21. Specifically, the first part 20 includes two flanges 22 formed between the two ribs 23. The first recess 21 is formed between the two flanges 22 and the two ribs 23. Each first flange 22 includes a notch 221 which communicates with the first recess 21.

[0023] The two clamp members 30, 301 are shaped symmetrically to each other, and each of the two clamp members 30, 301 includes a groove 31 defined in the inside thereof. Each of the two clamp members 30, 301 includes two ridges 32 respectively extending outward from two sides thereof. The two respective grooves 31 form a space so as to clamp the seat tube 71 of a bicycle within the space as shown in FIGS. 3 and 4.

[0024] The second part 40 includes a second recess 41 defined in the inside thereof so that one of the two clamp members 301 is accommodated in the second recess 41 of the second part 40 as shown in FIG. 3. Two through holes 43 are defined through the second part 40 and are located corresponding to the two threaded holes 25 of the first part 20. In this embodiment, each rib 23 includes a plug 24 received therein and the threaded hole 25 is located at the center of the plug 24. The second part 40 further includes two arms 42 respectively extending from two sides thereof and toward the first part 20.

[0025] The two arms 42 are mounted to two respective outsides of the two ribs 23 when the first and second parts 20, 40 are connected to each other by the two fasteners 50 that respectively extend through the two through holes 43 of the second part 40 and are threadedly connected to the threaded holes 25 of the first part 20. Each fastener 50 includes a head 51 and a threaded shank 53 extending from the head 51. The threaded shank 53 extends through the through hole 43 and is threadedly connected to the threaded hole 25 corresponding thereto. The head 51 of each fastener 50 is a semi-sphere head which includes first positioning portions 52 that are formed along the curvature of the semi-sphere head and spaced apart from each other. The three first positioning portions 52 are located not symmetrical to each other. The three first positioning portions 52 can be three cutouts or three protrusions with individual depth or length, and the three first positioning portions 52 are located not symmetrical to each other.

[0026] Referring to FIG. 5, the key 55 that is used to unscrew the fasteners 50 includes a skirt portion formed to one end thereof, and a chamber 551 is formed in the skirt portion. Three second positioning portions 56 are formed to the inner end or inner periphery of the chamber 551. The head 51 of each fastener 50 accommodated in the chamber 551 of the key 55. The three first positioning portions 52 and the three second positioning portions 56 are engaged with each other. The key 55 is rotated to rotate the fastener 50 such that the second part 40 is separated from the first part 20. The key 56 and the fasteners 50 are similar to applicant's former patent U.S. Pat. No. 6,341,927.

[0027] As shown in FIGS. 3, 4 and 5, when using the tracking element protection device 10 to a bicycle 70, the tracking element 60 is received in the first recess 21 of the first part 20, the two clamp members 30, 301 are mounted to the seat tube 71, and the first and second parts 20, 40 are then connected to each other by using the two fasteners 50 as mentioned above to secure the two clamp members 30, 301. The two arms 42 are located outside of the two ribs 23 to prevent foreign objects from entering into the tracking element protection device 10.

[0028] By using Bluetooth technology, the user can track the tracking element 60 by his/her smart phone, and positioning the tracking element 60 cooperated with the map of the smart phone.

[0029] As shown in FIG. 6, the tracking element protection device 10 can also accommodate a different type of tracking element 601 when the smart phone uses a different operation system. FIG. 7 shows that the tracking element protection device 10 is secured to the front suspension device 81 of a motorbike 80.

[0030] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
