[0003]

However, in the above-mentioned conventional monitor installation stand, in order to rotate the monitor in the horizontal plane, the wing bolts must be temporarily loosened and the base must be freely rotatable. There is a problem that the work for doing so is very troublesome, and if the usage period becomes long, the sandwiching part and the base will wear out, and it will not be possible to securely fix the base. The problem is occurring. In particular, when used in a vehicle such as an automobile, the problem arises that the butterfly bolt is loosened due to vibration during traveling, causing the monitor to drop.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a monitor installation stand by which the monitor can be easily rotated and the monitor can be surely installed. And

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 4, reference numeral 1 denotes a monitor installation stand, which has a mounting plate 2 having a substantially semicircular shape, and the mounting plate 2 has five notches 2a formed radially. A substantially cylindrical main body 3 is installed on the mounting plate 2,
The upper surface of the main body 3 has teeth 3a around the entire circumference.
Is molded. The teeth of the tooth portion 3a are formed in a shape having at least one inclined surface. A fitting hole 3b is formed through the main body 3 along the axis, and the lower portion of the fitting hole 3b is formed to have a diameter larger than that of the upper portion so that a biasing means described later can be fitted therein. Is configured.

A turntable 4 is mounted on the main body 3. The rotary table 4 is composed of a shaft portion 4a and a circular pedestal 4b integrally formed near the middle of the shaft portion 4a. The lower surface of the pedestal 4b of the rotary table 4 has teeth 3a of the main body 3 and The meshing tooth portion 4c is formed over the entire circumference in the vicinity of the circumference. In addition, the shaft portion 4 protruding below the pedestal 4b
a is inserted into the fitting hole 3b of the main body 3, and a spring receiver 4d is attached to the lower end thereof. Due to the difference in diameter between the spring receiver 4d and the upper surface of the lower part of the fitting hole 3b, that is, the fitting hole 3b. A compression spring 5, which is an example of an urging means, is inserted between the stepped surface and the step surface, and the rotary table 4 is always urged downward by the compression spring 5.

A joint 6 is connected to the shaft portion 4a of the rotary table 4 which projects upward from the pedestal 4b. A screw portion 6a is formed on the upper portion of the joint 6, and a circular platform 7 is screwed onto the screw portion 6a so as to be rotatable and movable along the screw portion 6a. A mount 8 is installed. On the other hand, a butterfly bolt 9, which is an example of a locking means, is inserted through the rotary table 4 in a direction orthogonal to the axis, and the joint 6 is screwed into the butterfly bolt 9 to loosen the butterfly bolt 9. The butterfly bolt 9 is configured to be rotatable in a vertical plane as a fulcrum. Further, as shown in FIG. 5, a projection 6c as a friction means is circularly arranged on the contact surface 6b of the joint 6 with the rotary table 4. The projection 6c is formed with a sharp tip, and when the wing bolt 9 is tightened, the projection 6c is crimped or bites into the rotary table 4. The monitor installation stand 1 of the present embodiment corresponds to the installation of the monitor 10 having the mounting portion 11 on the back surface of which the plate members 11a having a substantially L-shaped cross section are arranged in parallel as shown in FIG. The mount 8 and the platform 7 are configured as holding means for holding the monitor 10.

As described above, the teeth of the tooth portions 3a and 4c, which are formed so as to be meshed with the main body portion 3 and the rotary base 4, respectively, have a shape having at least one inclined surface. As the shape, for example, a shape in which an inclined surface and a vertical surface shown in FIG.
Examples include a shape in which two inclined surfaces shown in (b) are continuously arranged. Also, as shown in FIG. 6 on the top and bottom of these teeth.
When the roundness shown in (c) is given, the movement of the teeth becomes smooth when the turntable 4 is rotated. In addition to the above-mentioned protrusions, it is also possible to use packings made of a material having a high frictional resistance such as a rubber material or leather as the friction means, and the friction means can be obtained by providing the rotation table 4 side. The effect is similar.

The monitor installation stand 1 is a monitor 10
After fitting the mounting base 8 to the mounting portion 11 provided on the back surface, the platform 7 is rotated and moved upward, and the mounting unit 8 of the monitor 10 is held by the mounting platform 8 and the platform 7 to hold the monitor 1.
It holds 0. The angle adjustment of the monitor 10 attached in this way can be performed in two directions by the rotation of the rotary table 4 and the rotation of the joint 6. The angle adjustment of the monitor 10 in the vertical plane is performed by loosening the wing bolt 9, rotating the joint 6 with respect to the rotary table 4, and tightening the wing bolt 9 again at a desired position. At this time, the projection 6c of the joint 6 is pressed against the rotary table 4 or bites into the rotary table 4, so that the contact resistance between the joint 6 and the rotary table 4 is increased, and the joint 6 is strongly prevented from rotating.

The angle of the monitor 10 in the horizontal plane is adjusted by rotating the turntable 4 about its axis. When the rotary table 4 is rotated around its axis, the teeth 4 of the rotary table 4 are rotated.
c moves along the tooth portion 3 a of the main body portion 3. At this time,
Since the teeth of the teeth 4c of the rotary table 4 move along the inclined surfaces of the teeth of the teeth 3a of the main body 3, the rotary table 4 rises against the bias of the compression spring 5. When the teeth of the tooth portion 4c of the rotary table 4 cross over the teeth of the tooth portion 3a of the main body portion 3, the rotary table 4 is positively engaged with the tooth portion 3a of the main body portion 3 by the biasing force of the compression spring 5,
As a result, the monitor 10 is rotated and fixed by one tooth. When the rotary table 4 is continuously rotated, the above-described phenomenon continues and the rotary table 4 is securely fixed at the desired position.

[0013]

As described above in detail, in the monitor installation stand of the present invention, the rotary base is arranged coaxially with the main body, and the main body and the rotary base are formed with tooth portions which mesh with each other. Since the rotary base is constantly urged toward the main body by the compression spring, the angle of the monitor can be adjusted simply by rotating the rotary base, which simplifies the operation and the biasing of the compression spring. When the rotary base is not rotated, the teeth of the main body and the rotary base are always in mesh with each other, and these can be stably fixed, so that the monitor can be reliably installed.

Further, since the tooth profile of the tooth portion formed on the main body portion and the rotary base has a rounded top and bottom, the rotary base rotates smoothly, which causes the rotary base to rotate. Has less power for
There is an advantage that the operability when adjusting the angle of the monitor is further improved, and further, there is an advantage that the wear of the teeth is prevented and the life of the teeth is kept long.

Further, since a projection having a sharp tip is formed on the surface of the joint that comes into contact with the rotary base, the contact resistance between the joint and the rotary base is increased, and rotation of the joint due to the weight moment when the monitor is held is prevented. It is possible to obtain effects such as prevention and the ability to always hold the monitor stably.
