Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to display devices, particularly CRT support mechanisms, and is capable of freely changing the direction of the CRT screen with a minimum number of parts. The present invention relates to a support mechanism for a display device that can be assembled very easily.

[Background of the idea]

Conventionally, various support mechanisms have been known that can provide the above-mentioned CRT screen directionality, such as rotation, up-and-down motion, and the like.

However, the support mechanism of this conventional display device requires a large number of parts to achieve the desired operation.
Furthermore, because of the complicated structure, it was difficult to mold each part, troublesome to assemble, and the strength was weakened.

[Purpose of invention]

Therefore, the present invention was devised by focusing on the problems of the above-mentioned conventional technology.It solves these problems and minimizes the number of required parts.
It is an object of the present invention to provide a support mechanism for a display device that can be easily assembled.

[Means for trying to solve problems]

In order to achieve this purpose, the support mechanism of the display device according to the present invention has a positioning piece protruding from the upper part with an engaging claw, and a rigid spring piece above the shaft body having a screw hole formed on the lower surface. A fixing member arranged in a radial manner, an oblong hole formed at the bottom thereof through which the shaft body of the fixing member is inserted, and a groove in which the engaging claw is engaged at the edge of the opening surface, and a concave spherical upper surface for mounting. a movable support member having a movable support member, and a receptacle at the lower end of the shaft body of the fixation member, in which the movable support member is placed, a groove portion is formed in the bottom portion in which the positioning piece of the fixation member engages, and a screw insertion hole is bored. It is characterized by being comprised of a base member in which a hole is formed.

[Effect]

By configuring the support mechanism for the display device as described above, after each member is assembled and positioned, the screws are tightened and the rigid spring pieces of the fixing member are used to The movable support member can change its position freely while being sandwiched between the rigid spring piece of the fixed member and the base member, and is also braked, which reduces the number of parts and makes assembly extremely easy. It is possible to do this.

〔Example〕

Next, an example of the implementation of the present invention will be described in detail with reference to FIGS. 1 to 7.

FIG. 1 is an exploded perspective view of a support mechanism for a display device according to the present invention, and numeral 1 in the figure represents a fixing member made of hard plastic. This fixing member 1 has a shaft body 2 with a screw hole 2a (bush) formed on its lower surface. Furthermore, downward U-shaped positioning pieces 3, 3 arranged at 180 degrees are protruded from the outer surface of the shaft body 2, and engaging claws 4 are provided on the upper parts of the positioning pieces 3, 3, respectively. There is. Furthermore, this fixing member 1
is provided with a plurality of rigid spring pieces 5, 5, .

In addition, 6 in the figure is a movable support member on which a display device such as a DRT is mounted, and this movable support member 6 has holes 7, 7, etc. for screws that fix the display device formed in the four corners, and a roughly oval-shaped support member in the center. The mounting portion 8 of the fixing member 1 has a concave spherical upper surface and bulges downward.
have. An oblong hole 9 whose longitudinal direction is the longitudinal direction is formed at the bottom of the mounting portion 8, and the shaft body 2 of the fixing member 1 is protruded from both sides of the opening back of the oblong hole 9 toward the front. Grooves 10, 10 are formed in which the engaging claws 4, 4 on the provided positioning piece 3 are engaged. That is, by inserting the shaft body 2 of the fixing member 1 from above the oblong hole 9 of the mounting part 8 and rotating it 90 degrees to shift the fixing member 1 forward, the engaging claw 4 of the fixing member 1 is inserted. , 4 are engaged with the grooves 10, 10, and for the time being, the fixed member 1 is connected to the movable support member 6.
It is attached and fixed to.

Further, reference numeral 11 in the figure is a base member to be placed on a tabletop or the like, and this base member 11 has an arc-shaped recess 12 approximately the same diameter as the back surface of the mounting portion 8 of the movable support member 6 at approximately the center thereof. is formed, and supports the back surface of the mounting portion 8 of the movable support member 6 inside the opening edge 12a of the recess 12. Furthermore, a movable support member 6 is provided at the bottom of this recess 12.
A receiving hole 13 is formed into which the lower end of the shaft 2 of the fixing member 1 inserted through the oblong hole 9 is fitted, and a positioning piece protruding from the shaft 2 is provided at the opening edge of the receiving hole 13. Groove parts 14, 14 are formed in which the parts 3, 3 are engaged. Further, the fixing member 1 is inserted into this receiving hole 13.
A screw insertion hole 15 communicating with the screw hole 2a of the shaft body 2 of
A screw 16 is screwed into the hole from below. By screwing this screw 16, as originally shown in FIG.
10, the shaft body 2 is pulled downward by the bending of the rigid spring pieces 5, 5..., and its lower end is brought into close contact with the receiving hole 13, and the shaft body 2 By lowering the locking claws 4, 4 and the groove 1
0 and 10 are disengaged, and the movable support member 6 becomes movable while being sandwiched between the base member 11 and the rigid spring pieces 5, 5, . . . of the fixed member 1. Moreover, its movement is possible due to the shape of the oblong hole 9 through which the shaft body 2 is inserted and the shape of the mounting part 8, and it is also possible to rotate and raise and lower the body by pressing the rigid spring pieces 5, 5... It is also braked by pressure to maintain the changed position.

[Effect of idea]

As described above, the support mechanism for a display device according to the present invention is composed of only a base member, a movable support member, a fixed member, and one screw, and the number of parts is greatly reduced. It has an easy structure. Also, the assembly work does not require precision, but is necessarily matched by blind alignment, making it very easy and strong.
