2. Description of the Related Art Conventionally, a ball stud having a spherical body and a shaft portion has been rotatably provided in a holding member having a substantially cylindrical shape as a support for supporting a camera or a liquid crystal television receiver in an adjustable angle. There is known a support with an angle adjusting function which is configured to be held and to fix the relative angle between the holding member and the shaft portion by applying a pressing force to the sphere in the holding member (actually developed shokai). 64-45098, etc.). According to this, the spherical portion of the ball stud is pressed against the inner surface of the holding member by the thrust generated by tightening the screw, and thereby the mutual fixing of the ball stud and the holding member is achieved.

In order to enhance the mutual coupling force between the ball stud and the holding member, it is desirable that the inner surface of the holding member and the outer surface of the sphere are in close contact with each other. In the above-mentioned prior examples, a soft synthetic resin material or urethane is used. A structure in which a sphere is formed of a rubber material or the like is disclosed.

[0004]

[Problems to be Solved by the Invention] However, when the sphere portion is formed of a soft synthetic resin material or urethane rubber material as described above, the entire sphere becomes a soft material. The bond strength of is a problem. Further, the sphere itself may be deformed for a long period of time, which tends to lack durability.

On the other hand, a construction in which a spherical body is formed of a hard material and a saucer, which is a member different from the spherical body, is pressed against the spherical body, is actually used.
Although it is disclosed in Japanese Patent No. 193, in this case, since the assembling of the saucer is troublesome and the saucer is a separately separated member, the number of parts increases, which is not preferable.

At the same time, in the above-mentioned support, the article to be supported is generally attached to the free end of the ball stud, but the structure is such that it is formed at the tip of the stud shaft. Since the male screw is formed on the mating article, it is screwed onto the screw, and the stud bolt must be screwed into the target article, and the work of attaching and detaching the article to and from the support is troublesome. It was difficult to put on and take off quickly in front of.

The present invention was devised in order to eliminate such inconvenience of the prior art, and its main purpose is to secure the strength of the entire ball stud and to improve the reliability of the angle fixing. An object of the present invention is to provide a support with an angle adjustment function that can achieve the improvement of the detachability of the article to be supported as well as the simplification of the assembling work and the parts management.

[0008]

According to the present invention, such an object is provided in a substantially cylindrical holding member, a sphere rotatably held in the holding member, and an upper portion of the holding member. A ball stud having a shaft portion projecting from the opening, a connecting means for attaching an article to the free end of the shaft portion, and a shaft for pressing the spherical body in the holding member. A supporter with an angle adjusting function having a pressing means for fixing the angle of the portion, wherein the pressing means is a screw formed on the inner surface of the holding body, and a male screw screwable to the female screw and A pressing member having a concave surface formed on the axial end surface corresponding to the spherical surface of the spherical body, wherein the spherical body is a soft material forming a hemispherical portion integral with the shaft portion and a contact portion with the concave surface. It consists of a hemisphere formed by Is achieved by providing the angle adjusting function support characterized by comprising so as to couple these both hemispheres portions have engaging means having a complementary shape. In particular, it is preferable to provide locking means for locking each other with the elasticity of the material itself between the free end of the shaft and the connecting means.

[0009]

According to this structure, since the portion of the ball stud that comes into contact with the holding member and the portion that is connected to the article to be supported can be integrally formed of a material having high rigidity, there is no problem in strength. . Further, since the portion directly contacting the pressing member can be formed of a soft material, mutual adhesion at the time of fixing is improved. Moreover, since the soft material portion can be easily attached and detached, workability at the time of assembly or repair is improved. In addition, the work of attaching and detaching the stud portion and the target article can be performed with a so-called one-touch operation.
