Abstract

An angle adjustment apparatus for an electronic device according to the present invention can be inexpensively formed by a compact and simple structure and readily assembled and disassembled. When a telephone set as an electronic device is in a small inclination position, auxiliary plates are substantially in parallel to supports of a leg. Tips of the auxiliary plates are brought into abutment against right surfaces of the first projections. Click portions of the supports are brought into abutment against left surfaces of the second projections. Accordingly, the supports cannot be further rotated counterclockwise with respect to the base. When the telephone set is in a large inclination position, the auxiliary plates are perpendicular to the supports. The tips of the auxiliary plates are brought into abutment against the engagement portions of the base. The click portions of the supports are located between the first projections and the second projections. Accordingly, the supports cannot be further rotated counterclockwise with respect to the base.

Claims

1. An angle adjustment apparatus for an electronic device, said angle adjustment apparatus comprising:

a base having an engagement portion and a first projection;

a leg support rotatably attached to said base, said leg support being capable of being selectively in a parallel position in which said leg support is substantially in parallel to said base, a first inclination position in which said leg support is inclined at a first angle with respect to said base, and a second inclination position in which said leg support is inclined at a second angle with respect to said base; and

an auxiliary plate rotatably attached to said leg support, said auxiliary plate being brought into abutment against said engagement portion of said base to prevent rotation of said leg support so as to hold said first inclination position of said leg support when said auxiliary plate is raised with respect to said leg support and brought into abutment against said first projection of said base to prevent rotation of said leg support so as to hold said second inclination position of said leg support when said auxiliary plate is substantially in parallel to said leg support.

2. The angle adjustment apparatus as recited in claim 1, further comprising another set of said base, said leg support, and said auxiliary plate.

3. The angle adjustment apparatus as recited in claim 1, wherein said base has a rotation stopper formed between said engagement portion and said first projection for stopping rotation of said auxiliary plate.

4. The angle adjustment apparatus as recited in claim 1, wherein said leg support has a click portion formed at a tip of said leg support,

wherein said base has a second projection,

wherein said click portion gets over said first projection when said auxiliary plate is brought into abutment against said engagement portion of said base and gets over said second projection when said auxiliary plate is brought into abutment against said first projection of said base.

5. The angle adjustment apparatus as recited in claim 1, wherein said base has a recess and a pair of axes projecting on surfaces of said recess so as to face each other,

wherein said leg support has a pair of holes for receiving said pair of axes of said base so that said leg support is attached to said base.

6. The angle adjustment apparatus as recited in claim 5, wherein said leg support has a pair of guide recesses formed so as to guide said pair of axes of said base into said pair of holes when said leg support is substantially in parallel to said base.
