Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tilt mechanism for a display device such as a CRT.

[Prior Art] Displays such as CRTs are generally provided with a tilt mechanism to adjust the vertical angle.

FIG. 4 is a diagram showing a conventional tilt mechanism,
This is disclosed as Utility Model Application Publication No. 56-52370.

A fixed shaft 5 is connected between the bracket 4 at the rear of the top surface of the base 25 and the bracket 8 at the bottom of the monitor television 7.
and a torsion spring 9.

On the other hand, a friction sliding part 11 is provided in front of the upper surface of the base 25, and a threaded rod 13 and a nut 1 on the base 25 side are provided.
5, a compression spring 16, a presser plate 14, etc., and a friction plate 19 on the monitor TV 7 side.
The slit hole 20 of the friction plate 19 is connected to the threaded rod 13.
is inserted into. As a result, the torsion spring 9
The angle of the monitor television 7 can be varied up and down by the friction sliding part 11 and the friction sliding part 11.

[Problem to be solved by the invention] However, the above-mentioned tilt mechanism has torsion springs 9 at the front and rear between the base 25 and the monitor TV 7.
and the friction sliding portion 11 must be provided, and the torsion spring 9 portion and the friction sliding portion 11 must be provided.
Due to the weight balance of the monitor television 7, it was necessary to maintain a distance of at least a predetermined distance between the monitor television 7 and the monitor television 7.

Therefore, the tilt mechanism wastes most of the area on the base 25 and requires maintenance at multiple locations due to the large number of parts.

In addition, most tilt mechanisms normally adjust the angle of the monitor TV upward from the reference horizontal position, and in order to adjust the angle of the conventional tilt mechanism, it is necessary to fix the central The shaft 5 and the torsion spring 9 cannot be placed in front of the base 25, but must be placed behind the base 25. Since the monitor television 7 has a heavy weight at the front where the screen is due to its shape, the torsion spring 9 provided at the rear of the monitor television 7 is inevitably large, which is not preferable from a structural standpoint. This increases the distance between the base 25 and the monitor television 7, which is not desirable in terms of appearance.

On the other hand, if the distance between the base 25 and the monitor television 7 is narrowed, the slit hole 2 in the friction sliding part 11
Since the length of 0 cannot be made large, the angle adjustment range of the monitor television 7 becomes narrow.

The present invention was developed in view of the above-mentioned problems, and is a tilt mechanism that can adjust the angle of a display device such as a monitor television. It can be installed in a small space, has a simple number of parts and structure, and is easy to maintain.Furthermore, the display device and the base are placed as close together as possible to obtain an excellent appearance, and the tilt mechanism of the display device has a wide angle adjustment range. is intended to provide.

[Means for Solving the Problem] In order to achieve the above object, the tilt mechanism of the display device of the present invention is provided on the top of the base 25 and changes the angle of the front surface of the display section 28 on which various screens are displayed. The tilt mechanism of the display device includes: a bearing 30 provided on the base and pivotally supporting the fixed shaft 32 in a fixed state; and a bearing 30 provided at the center of gravity of the lower surface of the display section 28, and pieces 31a at both ends thereof. A bracket 31 is inserted through the fixed shaft and is rotatable with respect to the bearing, and both ends 34a are fixed to the base, and a twisted portion 34b inserted through the fixed shaft is formed near both ends. a spring 34 having a bent portion 34c formed therebetween that contacts the bracket and urges the display unit forward; a spring 34 that is fixed concentrically to the end of the fixed shaft;
It is characterized by comprising spacers 35a and 35b that sandwich the pieces of the bracket to generate a predetermined frictional force.

[Function] The display unit 28 is connected to the base 25 via a bracket 31, a fixed shaft 32, and a bearing 30. The spring 34 of the fixed shaft 32 holds the display section 28 at a predetermined angle.

When adjusting the angle of the front surface of the display section 28, it is sufficient to apply only the frictional force between the spacers 35a, 35b and the bracket 31 of the display section 28.

[Example] FIG. 1 is a diagram showing a tilt mechanism of a display device of the present invention.

The front surface of the base 25 is provided with an LED 26 for displaying POWER and a keyboard connector 27 (not shown).

On the top surface of the base 25, there is a display unit 2 such as a CRT.
8, and a tilt mechanism 29 is provided between the center of gravity of the cathode ray tube or the like on the lower surface of the display section 28 and the upper surface of the base.

Therefore, this tilt mechanism 29 is located at a slightly forward portion of the base 25. FIGS. 2a and 2b are a partially enlarged plan view and a front view showing the mechanical part of the tilt mechanism 29. FIG.

A U-shaped bearing 30 is fixed on the base 25, and a bracket 3 is mounted on the display section 28.
1 is fixed. Piece 31 of bracket 31
A is located inside part 30a of the bearing 30, and between the parts of the bearing 30 and the bracket 31, a half-moon-shaped fixed shaft 32 with a part cut out is provided as shown in FIG. It is being

One end 32a of this fixed shaft 32 is connected to a half-moon-shaped receiving hole 30 formed in one piece 30a of the bearing 30.
aa to prevent shaft rotation, and the other end 32b is formed with a small diameter portion 32ba having a small shaft diameter and a bolt portion 32bb. It is provided by fitting through it and fixed by a nut 33.

Further, a torsion portion 3 of one spring 34 is disposed between the bearing 30 of the fixed shaft 32 and the bracket 31.
4b is inserted, and this spring 34 is
Both ends 34a, 34a are the receiving holes 30b of the bearing 30
The bent portion 34c of the central portion is in contact with the bracket 31. This spring 34 urges the display section 28 forward through the bracket 31 around the fixed shaft 32.
This force acts until it reaches the point where it tilts most forward,
It is set to a value that cancels the weight of the display section 28.

Further, the small diameter portion 32b of the fixed shaft 32 has a stepped portion 32c of the fixed shaft 32 and the bracket 3.
A circular spacer 35a made of a resin material such as Delrin and eccentrically upward relative to the center of the fixed shaft 32 is provided between the spacer 35a and one surface of the piece 31a of the fixed shaft 32. On the other hand, the other surface of the piece 31a of the bracket 31 and the bearing 3
A spacer 35b having the same diameter as the spacer 35a is also provided between the spacer 35a and the spacer 35a.

The eccentricity of the spacers 35a and 35b is provided to provide a distance between the display section 28 and the base 25.

The small diameter portion 32ba of the fixed shaft 32 is also formed in a semicircular shape, and the spacers 35a, 35b are formed with semicircular fitting holes 35aa, 35ba corresponding to the semicircular small diameter portion 32ba. Further, the spacer 35b is provided with a stopper 35bb,
This stopper 35bb is fitted into a fitting groove 30b formed in one piece 30a of the bearing 30.

Therefore, both of the spacers 35a and 35b do not rotate relative to the fixed shaft 32.

Therefore, to assemble the tilt mechanism 29, after inserting the bracket 31, spring 34, and spacers 35a, 35b into the fixed shaft 32,
This can be done by simply inserting one end 32a into the receiving hole 30aa of the bearing 30 and fixing the nut 33 at the other end 32b.
The frictional force exerted by the brackets 5a and 35b on the bracket 31 can be varied.

Pieces 30a, 30a of the fixed bearing 30
are cases 3 each made of plastic.
6, and furthermore, this case 3
6 is integrally molded with the turntable 37.

The turntable 37 is formed in the shape of a disc with a predetermined diameter, and the sliding piece 38a of the sliding part 38 made of a resin material such as Delrin slides on the iron plate 39 on the top surface of the base 25, so that the turntable 37 is rotated against the base 25. The display section 28 is configured to move circularly. A circumferential groove 37a is formed on the entire outer circumference of the turntable 37. On the other hand, a protruding piece 39a of the case 39 provided on the surface of the base 25 is located above the circumferential groove 37a. This prevents it from leaking upward.

Further, the bracket 31 portion is covered by two mating plates 40a and 40b fixed to the lower part of the display section 28, as shown in FIG. Through holes 31 are formed in the bracket 31, the upper surface of the base 25, and the mating plates 40a and 40b, respectively.
b, 31c, 25c, 40c are opened, and various signal lines of the display section 28 are connected to the through holes 31b, 31c, 25 of this tilt mechanism 29 part.
c and 40c.

Next, the operation of the tilt mechanism 29 having the above structure will be explained. To adjust the tilt mechanism 29 to any horizontal direction, the operator holds the display section 28 and rotates it left and right. As a result, the sliding piece 37a of the turntable 37 slides on the iron plate 38 of the base 25. Furthermore, as shown in the side view of FIG. 3, when holding the display section 28 and adjusting the angle up and down, the spring 34 cancels out the weight of the display section 28. Therefore, the force required at this time is only the frictional force of the bracket 31 sandwiched between the spacers 35a and 35b, and the angle can be adjusted with only a light force, and after adjustment, this frictional force maintains the position of the display part 28. .

The tilt mechanism 29 configured as described above is provided at the center of gravity of the display section 28, and the spring 34 can be made smaller. In addition, the tilt mechanism 29
can be installed between the display section 28 and the base 25 with a minimum area, so the turntable 37 can be made with a small diameter that is close to the maximum width of the tilt mechanism 29, and the appearance is also excellent. It can be made into

In the above-described embodiment, the spacer is provided only on one of the pieces 31a of the bracket 31, but it may be provided on either of the pieces 31a of the bracket 31.

Further, the display section 28 may be in a form other than a cathode ray tube, such as a CRT.

[Effects of the Invention] As explained above, according to the tilt mechanism of the display device according to the present invention, the tilt mechanism can be provided on the base with a minimum area between the display unit and the display unit.

Further, it is possible to obtain a display device with a small number of parts, a simple structure, excellent maintainability, and an aesthetically pleasing appearance.
