## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to fastener means and more particularly, to a device clip for linking a first object to a second object.
2. Description of the Related Art
In order to facilitate movement, most people when they travel carrying a backpack with a camera usually will put the camera in the backpack. When going to take pictures, they have to open the backpack and then pick up the camera from the backpack. It is inconvenient and time-consuming inconvenience to access to the camera in this manner. On the contrary, carrying a camera on the shoulder for the convenience of taking pictures at any time, will, in turn, limited mobility, resulting in facing a dilemma.
In order to solve this problem, a user may insert a Velcro tape 10 (the so-called “magic tape”), as shown in FIG. 1, through a loop 21 of his(her) camera bag 20 and a loop (not shown) of his(her) backpack (not shown) and then fasten up loop tape portion 11 and hook tape portion 13 of the Velcro tape 10 to secure the camera bag 20 to the backpack. Thus, when the user carries the backpack on the back, the camera bag 20 is kept attached to the outside of the backpack, facilitating access to the camera at any time. However, after a long use, the Velcro tape 10 will reduce its binding force, resulting in connection instability between the backpack and the camera bag 20. When the binding force of the Velcro tape 10 becomes insufficient, the user must replace the Velcro tape 10.

DETAILED DESCRIPTION OF THE INVENTION
Before reviewing the following description of the invention, it is to be understood that inner, outer, up, down and other directional terms as defined throughout the whole specification are based on the direction indicated in the annexed drawings.
Referring to FIGS. 2 and 3, a device clip 30 in accordance with a first embodiment of the present invention is shown comprising an elongated first jaw member 40 and an elongated second jaw member 50.
The first jaw member 40, can be made of, but not limited to, plastics, comprising a pivot connection part 41, a locking part 43, and a body part 45 connected between the pivot connection part 41 and the locking part 43. In this embodiment, the locking part 43 is a hook formed integral with one end of the body part 45. The pivot connection part 41 is formed of two protrusions extend that extend from an opposite end of the body part 45 toward an inner side 401 of the first jaw member 40. Further, the locking part 43 comprises a retaining groove 431, a front hook portion 433 extending from one side of the retaining groove 431 in direction toward the inner side 401 of the first jaw member 40, and a guide face 435 located on a front side of the front hook portion 433. The body part 45 comprises a plurality of through holes 451 for the insertion of rivets or like fastening members to affix the first jaw member 40 to, for example, a backpack, facilitating linking between the backpack and another object at any time.
The second jaw member 50, can be made of, but not limited to, plastics, comprising a pivot connection part 51 pivotally connected to the pivot connection part 41 of the first jaw member 40, a locking unit 53 detachably lockable to the locking part 43 of the first jaw member 40, and a body part 55 connected between the pivot connection part 51 and the locking unit 53. In this embodiment, the locking part 43 is a hook formed integral with one end of the body part 45. The locking unit 53 comprises two lugs 60 protruding in direction toward an inner side 501 of the second jaw member 50, a rod member 70 inserted through the two lugs 60, and an escape hole 80 cut through the inner side 501 and outer side 503 of the second jaw member 50 corresponding to the rod member 70. Thus, the body of the rod member 70 forms a locking part 71.
Further, the body part 55 comprises a plurality of through holes 551 for the insertion of rivets or like fastening members to affix the first jaw member 40 to, for example, a backpack, facilitating linking between the backpack and another object at any time.
Further, as shown in FIG. 4, FIG. 6 and FIG. 8, each lug 60 comprises an oblong hole 61 extending in the direction of the major axis of the second jaw member 50, a recess 63 extended from the hole wall of the oblong hole 61 toward the pivot connection part 51, and a spring 65 accommodated in the recess 63. Each oblong hole 61 has a small diameter portion 611 and a large diameter portion 613. Further, as shown in FIG. 2, FIG. 6 and FIG. 8, the two opposite ends 72 of the rod member 70 are respectively capped with a respective end cap, forming a respective operating portion 73.
During installation of the second jaw member 50, set the respective springs 65 in the respective recesses 63, and then insert the rod member 70 through the oblong holes 61 of the two lugs 60 to have the two opposite ends 72 of the rod member 70 be respectively accommodated in the respective oblong holes 61. At this time, the springs 65 are stopped against the rod member 70. Thereafter, attach the operating portions (end caps) 73 to the two ends 72 of the rod member 70. At this time, the operating portions 73 are abutted against the small diameter portions 611 of the associating oblong holes 61 and accommodated in the associating large diameter portions 613. Thus, the rod member 70 can be limited between the two oblong holes 61 and forced to move along the major axis of the second jaw member 50 and to compress the springs 65. After the applied force is disappeared, the springs 65 immediate return the rod member 70 to its former position.
When assembling the device clip 30, as shown in FIG. 2, pivotally connect the pivot connection part 51 of the second jaw member 50 to the pivot connection part 41 of the first jaw member 40 with a pivot, allowing the second jaw member 50 to be biased relative to the first jaw member 40. At this time, the first jaw member 40 is not locked to the second jaw member 50, and the rod member 70 of the second jaw member 50 is in the normal position, i.e., in the upper halves of the oblong holes 61. Thereafter, as shown in FIG. 5 and FIG. 6, when biasing the first jaw member 40 toward the second jaw member 50 to attach the front hook portion 433 of the locking part 43 of the first jaw member 40 to the rod member 70, the rod member 70 will be forced to compress the springs 65 and to move along the guide face 435 of the locking part 43 of the first jaw member 40 to the lower halves of the oblong holes 61. When continuously biasing the first jaw member 40 toward the second jaw member 50 to force the rod member 70 toward the retaining groove 431 of the locking part 43 of the first jaw member 40, as shown in FIG. 7 and FIG. 8, the rod member 70 will be released from the pressure, and the elastic potential energy of the springs 65 will immediately push the rod member 70 back to the upper halves of the oblong holes 61 to have the rod member 70 be engaged in the retaining groove 431 of the first jaw member 40. At this time, the first jaw member 40 and the second jaw member 50 are locked in the close position.
Thus, when using the device clip 30 to secure, for example, a backpack and a camera bag together, the body part 55 of the second jaw member 50 can be inserted through a loop (not shown) of the backpack, and the body part 45 of the first jaw member 40 can be inserted through a loop (not shown) of the camera bag, and then the backpack and the camera bag can be steadily linked together by engaging the rod member 70 into the retaining groove 431. Using the device clip 30 to link a backpack and a camera bag is simply an application example of the present invention. This application example is not a limitation. Further, the application of the device clip 30 is not limited to any particular mounting direction. In another application example, the first jaw member 40 can be inserted through the loop of the backpack, and the second jaw member 50 can be inserted through the loop of the camera bag.
FIG. 9 illustrates a device clip 30 in accordance with a second embodiment of the present invention. According to this second embodiment, each recess 63′ extends from the hole wall of the associating oblong hole 61 in a reversed direction relative to the pivot connection part 51 so that the rod member 70, when unstressed, is normally positioned in the lower halves of the oblong holes 61. Further, the front hook portion 433′ of the first jaw member 40 extends from one side of the retaining groove 431 toward the outer side 403 of the first jaw member 40. Thus, when biasing the first jaw member 40 toward the second jaw member 50 to attach the front hook portion 433′ to the rod member 70, the rod member 70 will be forced to compress the springs 65 and to move along the guide face 435 to the upper halves of the oblong holes 61. When the rod member 70 reaches the retaining groove 431, as shown in FIG. 9, the rod member 70 will be released from the pressure, and the elastic potential energy of the springs 65 will immediately push the rod member 70 back to the lower halves of the oblong holes 61 to have the rod member 70 be engaged in the retaining groove 431 of the first jaw member 40.
In conclusion, by means of engaging the rod member 70 of the second jaw member 50 of the device clip 30 in the retaining groove 431 of the first jaw member 40 for enabling the rod member 70 to be steadily held down in the retaining groove 431 by the elastic potential energy of the springs 65, the first jaw member 40 and the second jaw member 50 are firmly locked in the close position. Thus, the device clip 30 of the invention not only can overcome the drawbacks of the prior art method of using a Velcro tape to link two objects together, but also can be conveniently and rapidly mounted to link two objects together.
