Abstract

A holding bracket includes a main body having several guiding rails crossing one another at their centers, where a gearwheel is disposed rotatably; four claw units in the main body, each having a toothed section meshed with the gearwheel and a sliding section contacting a respective guiding rail and a holding section and a portion of the sliding exposed from the main body such that rotation of the gearwheel results in simultaneous movement of the claw units relative to the main body. A biasing unit is confined in the main body and associates with one claw unit. A one-way brake unit disposed in the main body is movable linearly and contacts the sliding section of one claw unit such that when the brake unit is under an unreleased condition, the four claw units are movable only in a single direction toward the gearwheel or the center of the main body.

First claim

What is claimed is:

1. A holding bracket, comprising:
a main body defining an interior space provided with a plurality of guiding rails crossing one another at their centers, where a gearwheel is rotatably disposed;
four claw units, each having a toothed section, a sliding section and a holding section, wherein said holding section and a portion of said sliding section are exposed to an exterior of said main body while said toothed section and another portion of said sliding section are confined within said interior space of said main body in such a manner that said toothed sections are meshed with said gearwheel at different parts and said sliding sections contact said plurality of guiding rails so that rotation of said gearwheel results in simultaneous movement of said four claw units with respect to said main body;
a biasing unit disposed in said main body for biasing said four claw units, thereby exposing said portion of said sliding section and said holding section of respective ones of said four claw units to said exterior of said main body; and
a one-way braking unit disposed movably within a braking frame, which is formed within said main body such that said one-way braking unit contacts with and is associated with one claw unit of said four claw units such that when said one-way braking unit is under an unreleased condition, said four claw units are only movable in a single direction toward said gearwheel.

2. The holding bracket according to claim 1 , wherein said main body is constituted by a front body and a rear body coupled to said front body for defining said interior space therebetween, wherein said plurality of guiding rails are formed in said rear body in an X configuration.

3. The holding bracket according to claim 1 , wherein said plurality of guiding rails include four guiding rails divided in two sets, disposed at different elevations, and said four claw units are divided in two sets, wherein each of said toothed sections has a width smaller than said sliding section of a respective one of said four claw units such that said toothed sections of one set of said four claw units are meshed with said gearwheel at the same elevation and extend in a parallel manner relative to each other while said toothed sections of another set of said four claw units are meshed with said gearwheel and extend in a parallel manner relative to each other at the same elevation below one another.

4. The holding bracket according to claim 1 , wherein said main body is constituted by a front body and a rear body coupled to said front body for defining said interior space therebetween, wherein said plurality of guiding rails include four guiding rails divided in two sets, disposed at different elevations, and wherein said rear body is further formed with four position limiting stems respectively extending from said four guiding rails, said sliding section of each of said four claw units is formed with an elongated slide slot permitting extension of a respective one of said four position limiting stems, thereby preventing untimely disengagement of said four claw units from said main body.

5. The holding bracket according to claim 1 , wherein said holding section extends perpendicularly from said sliding section of each respective claw unit of said four claw units and further has a triangular cross-section to compliment four corners of a mobile phone once said mobile phone is placed on said main body.

6. The holding bracket according to claim 2 , wherein said rear body further defines a spring-receiving chamber for accommodating said biasing unit therein such that said biasing unit has one end biasing a wall confining said spring-receiving chamber and the other end biasing one claw unit of said four claw units.

7. The holding bracket according to claim 1 , wherein said biasing unit and said one-way braking unit are connected to said four claw units but at different positions.

8. The holding bracket according to claim 1 , wherein said one-way braking unit includes a brake disposed movable linearly within said braking frame and having a row of inclined teeth, a brake spring disposed in said braking frame for biasing said brake, and a release button having an insert block formed with an inclined face, said brake defining a block-reception space for receiving said insert block therein and having a first inclined face in sliding contact with said inclined face of said release button, said sliding section of each claw unit of said four claw units has a unidirectional rack meshed with said inclined teeth of said brake when no external force is applied thereon such that pressing of said release button results in linear movement of said brake, which in turn, causes disengagement between said inclined teeth of said brake relative to said unidirectional rack of a respective one of said four claw units.

9. The holding bracket according to claim 8 , wherein said main body is constituted by a front body and a rear body coupled to said front body for defining said interior space therebetween, and wherein said release button is exposed at least partially from said rear body so as to facilitate manipulation by a user.
