Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present application relates to an angle adjusting mechanism for a mounting table such as a telephone or a small television set attached to a table or the like via a support.

2. Description of the Related Art Conventionally, a mounting table such as a telephone or a small television set mounted on a table or the like via a support column is tilt-adjusted in a vertical direction so that the direction of a telephone or a small television mounted on the mounting table can be changed. It is configured to be able to
The angle adjustment mechanism is, for example, a vertically rotatable connection of a mounting member mounted on the lower surface of the mounting table to a support member horizontally rotatably supported by a column, and a circle having the rotation point as a centroid point. An arc-shaped adjusting hole is provided in one of the support member and the mounting member, and a mounting shaft provided in one of the other is inserted into the adjusting hole, and the supporting member and the mounting member are tightened by screwing. It is.

However, according to the conventional configuration described above, since the mounting member is fixed to the support member by screwing, the operation of adjusting the angle of the mounting table is troublesome, and vibrations and the like are required. There is a concern that the mounting portion of the mounting table may lack stability due to the possibility of loosening of the screwed portion, and the mechanical strength is required, so it is not possible to use a synthetic resin that is lightweight and easy to manufacture. there were.

Therefore, the present application is intended to solve the above-mentioned disadvantages of the related art.

Means for Solving the Problems In order to achieve the above-mentioned object, the present application is mounted on a mounting table, and is supported by a support member so as to be vertically rotatable by a pivot, and the rotation point is defined as a centroid point. A fixing member having a bulging portion having a meshing surface on an arcuate surface, a meshing surface meshing with the meshing surface, and a first position at which the meshing surfaces mesh with each other, and the meshing state is released. An adjustment piece provided on the support member so as to traverse between the second position, an operation shaft for traversing the adjustment piece between the first position and the second position, And a biasing means for holding the adjustment piece at the first position. In the above, one of the meshing surfaces is formed of a single tooth, and the other meshing surface is A case where a plurality of meshing grooves selectively engaging with the teeth are continuously formed; Face
In some cases, a plurality of teeth may be formed continuously, and the fixing member and the adjustment piece are made of synthetic resin to facilitate manufacture and reduce the weight. A fixing member, an adjustment piece, and a biasing means having a pair of side pieces facing each other at an interval and having a bulging portion having an engagement surface in a part of the axial direction between the side pieces. Each is interposed, and the operation shaft is supported on a pair of side pieces so as to be able to move laterally, and the adjustment piece is supported non-rotatably on a part of it.

Operation Under normal conditions, the mounting table is fixed at a required angle with respect to the support member by the engagement between the engagement surface of the fixing member and the engagement surface provided on the adjustment piece, and the angle of the mounting table is changed from this state. When adjusting, when the operating shaft is pressed against the resilient means, the engaging surface of the adjustment piece is disengaged from the engaging surface of the fixing member, and the mounting table is freely tilted via the pivot shaft. When the operating shaft is released with the angle set at the required angle, the operating shaft is restored, the meshing surfaces are meshed again, and the mounting table is fixed at the adjusted angle.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. A mounting table (1) on which a telephone or the like is mounted supports a support (2).
Is mounted on a desk top plate (4) by a mounting bracket (3), and a support member (5) is rotatably supported on an upper portion of the column (2).

The supporting member (5) is provided on a side of the shaft cylinder (6) rotatably fitted to the support (2), and a pair of side pieces (7), opposed to each other at an interval P at a tip end thereof, An arm (8) having (7) is integrally protruded, and the pair of side pieces (7),
(7) is provided with first and second through holes (9) and (10) penetrating in the plane direction, respectively.

An angle adjusting element (11) is disposed between the pair of side pieces (7), (7) of the support member (5) thus configured.

The angle adjusting element (11) is fixed to the lower surface of the rectangular mounting table (1), and is integrally provided with an arc-shaped bulging portion (13) having a center hole (12) as a center point on the lower surface. A fixing member (15) made of a synthetic resin, comprising a meshing surface (14) in which one half of the longitudinal direction is formed to have a large diameter and a mountain-shaped tooth is continuously formed along the half circumferential surface; Adjustment made of synthetic resin having a concave meshing surface (16) that is continuous with mountain-shaped teeth meshing with (14), and having a square hole (17) penetrating in a direction orthogonal to the meshing surface (16). The second through hole (10) provided in the one side piece (7) normally penetrates the piece (18) and one end of the shaft portion (19) fitted into the square hole (17). A large-diameter operating portion (20) protruding outward is provided with a small-diameter support shaft (21) inserted through a second hole (10) provided in the other side piece (7) at the other end. An operating rod (22) extending integrally therewith; A spring (2) interposed between the adjustment piece (18) and the other side piece (7) for constantly urging the operating rod (22) toward the operating portion (20).
3) and the first hole (9) of the pair of side pieces (7) and (7) and the center hole (12) of the fixing member (15), and both ends are connected to the head. A pivot (24) fixed in the axial direction by an E-ring. (25) is a holding rod for holding a telephone or the like placed on the mounting table (1) from the side thereof, and (26) is a non-slip projection of the telephone or the like mounted on the mounting table (1). is there.

However, in a normal state, the mounting table () is engaged with the arcuate meshing surface (14) provided on the semi-peripheral surface of the fixing member (15) and the concave meshing surface (16) provided on the adjustment piece (18). 1) is fixed at a required angle with respect to the support member (5), and when adjusting the angle of the mounting table (1) from this state, the operating rod (22) is pressed against the spring (23). Then, the meshing surface (16) of the adjustment piece (18) is aligned with the meshing surface (1) of the fixing member (15).
4), the mounting table (1) is freely tilted via the pivot (24). Therefore, when the mounting table (1) is set at a required angle, the pressing of the operating rod (22) is stopped. When released, the operating rod (22) is restored and the meshing surfaces (14) and (16) are meshed again, and the mounting table (1) is fixed at the adjusted angle.

In the above description, the case where the meshing surfaces (14) and (16) are formed by connecting mountain-shaped teeth is exemplified. However, a single tooth is provided on one of the meshing surfaces, and the other meshing surface is connected to the teeth. Of course, it may be formed of a plurality of engagement grooves which are selectively engaged.

Effect of the Invention As described above, according to the present application, since the operation shaft is pressed against the resilient means to adjust the tilt angle of the mounting plate, the angle adjustment operation is extremely simple and convenient for handling. In addition, there is no possibility of loosening due to vibration or the like, and the mounting plate can be securely fixed, and according to the configuration of claim 5, it is easy to manufacture and effective for weight reduction. Having.
