Abstract

Provided is an adhesion device used to cradle a car navigation system, a mobile phone, etc. The adhesion device according to the present invention comprises a pad (21) having a bottom surface attached to an adhesion surface, a center element (23) fixed upright at the center of the top surface of the pad (21), a housing (22) placed on the top surface of the pad (21) and having a hole through which the center element (23) passes, a ring-shaped leaf spring (27) which is equipped at the outer circumference of the housing (22) and presses the outer circumference of the top surface of the pad (21) and an adhesion controller (24) connected with the top end of the center element (23) by an axis (24c). The adhesion controller (24) comprises a lever (24a) and a press (24b). When the lever (24a) is rotated around the axis (24c), the press (24b) presses down the top surface of the housing (22) and the center of the pad (21) connected with the center element (23) is moved upward, resulting in an expansion of the space between the pad (21) and the adhesion surface and a pressure lower than the atmospheric pressure.

Claims

1. An adhesion device comprising:

a pad (21) having a bottom surface attached to an adhesion surface;

a center element (23) fixed upright at the center of the top surface of the pad (21);

a housing (22) placed on the top surface of the pad (21) and having a hole through which the center element (23) passes;

a ring-shaped leaf spring (27) which is equipped at the outer circumference of the housing (22) and presses the outer circumference of the top surface of the pad (21); and

an adhesion controller (24) connected with the top end of the center element (23) by an axis (24c), wherein the adhesion controller (24) comprises a lever (24a) and a press (24b), such that, when the lever (24a) is rotated around the axis (24c), the press (24b) presses down the top surface of the housing (22) and the center of the pad (21) connected with the center element (23) is moved upward, resulting in an expansion of the space between the pad (21) and the adhesion surface and a pressure lower than the atmospheric pressure,

wherein the ring-shaped leaf spring (27) has separated branches (27a) at the outer circumference and the branches (27a) are equipped with bights (27b) that press the top surface of the pad (21).

2. The adhesion device as set forth in claim 1, wherein the center of the pad (21), which is connected with the center element (23), is thicker than the outer circumference and the top surface of the pad (21) is tapered at the center toward the outer circumference.

3. The adhesion device as set forth in claim 1, wherein the pad (21) is convex at the bottom surface and an adhesive industrial gel (25) is provided at the outer circumference of the bottom surface of the pad (21).

4. The adhesion device as set forth in claim 1, wherein at least one trunnion (22a) is formed at the bottom of the housing (22) which contacts the pad (21) and a coil spring (26) surrounding the center element (23) is further equipped between the housing (22) and the pad (21).
