Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an equipment support stand for supporting equipment such as a display device so as to be rotatable in the horizontal direction and also to support the inclination of the equipment in a variable manner. It is something.

[Conventional technology]

Conventionally, as this type of device support stand, there is a support stand for a display device, as shown in FIGS. 4 and 5, for example. This is fixed base 1
It is composed of a rotating base 2 that is rotatably provided on the top, and a tilting base 3 that is attached to the rotating base 2 so that its inclination can be changed. It is fixedly attached. In this way, the display device 4
The display surface 4c of the CRT 4b can be rotated horizontally as desired, and its inclination can also be varied as desired. By using such a support base, the display surface 4c can be set at a position that is most convenient for the operator.

By the way, in order to attach the rotating base 2 to the fixed base 1, a circular recess 5 is formed in the fixed base 1, a shaft 6 is provided vertically in the center, and a hole 7 is formed in the center of the rotating base 2. A shaft 6 is loosely fitted into the hole 7, and the rotating base 2 is supported so as to rotate on the fixed base 1 in the direction indicated by arrow A. A ring-shaped spacer 8 for reducing friction is arranged in the recess 5.
The rotating base 2 is designed to be rotated smoothly with respect to the fixed base 1. The tilting base 3 is attached to the rotating base 2 by forming a downwardly protruding curved surface 9 on the rotating base 2, and forming a pair of guide grooves 10 along the curved direction on this curved surface 9. Guide pins 11 to be inserted into the guide grooves 10 are provided vertically on the upper surface of the rotating base 2, and these guide pins 11 are inserted into the guide grooves 10 and engaged. A frame 12 is provided on the upper surface of the rotating base 2, and a curved surface 9 is provided within the frame 12.
A roller 13 is provided for smoothly tilting the tilting base 3 by receiving the lower surface of the tilting base 3. Therefore, the tilting base 3 is mounted on the rotating base 2 so as to be tiltable in the direction indicated by arrow B.

In addition, 14 connects the tilting base 3 to the display device 4.
This is a screw hole for fixing to the bottom surface 4a with a screw 14a.

[Problem that the invention attempts to solve]

However, in the past, the rotating base 2
Since the display device 4 had to support a large weight, it required considerable strength. Therefore, the material of the rotating base 2 needs to be an expensive material with strength in mind, and the wall thickness has to be increased, which requires a large amount of expensive material. Furthermore, since the rotating base 2 must be reinforced with ribs or the like, when it is made of a resin molded product, for example, there is a problem in that the cooling process during molding is hindered and productivity is deteriorated.

Further, in order for the rotating base 2 and the tilting base 3 to operate smoothly, a ring-shaped spacer 8 and a roller 1 are provided.
3, which caused problems such as increased costs due to an increase in the number of parts, increased costs and decreased productivity due to increased man-hours during assembly.

Furthermore, if the display device 4 is used for a long period of time with the desired inclination, the rollers 13 may undergo plastic deformation due to changes over time, and the rollers 13 may not rotate smoothly and the tilting base 3 may be tilted. There was a problem in that it sometimes caused an unpleasant movement phenomenon with looseness.

The present invention was devised in view of the above problems, and it is an object of the present invention to provide a device support stand that is low cost and capable of smooth rotational and tilting operations.

[Means for solving problems]

Means for achieving the above object of the present invention includes a rotating base that is horizontally rotatably mounted on a fixed base, and a rotating base that is fixed to the bottom of the device and located above the rotating base so that the inclination is variable. In an equipment support stand comprising a tilting base that is arranged so as to be tiltable, through-holes are respectively provided at positions corresponding to four corners forming a substantially quadrangular shape of the rotating base; and a spacer whose upper end abuts the lower surface of the tilting base and whose lower end abuts the upper surface of the fixed base.

[Effect]

In the above means, the weight of the device that the tilting base receives is transmitted to the fixed base via the spacer, and the weight of the device is not applied to the rotating base disposed between the fixed base and the tilting base. Further, it is intended that smooth rotational movement and tilting movement can be performed, and that the structure of the rotating base body can be simplified.

〔Example〕

Hereinafter, an embodiment of the present invention will be described based on FIGS. 1, 2, and 3, and the same parts as those in the prior art will be given the same reference numerals and the explanation thereof will be omitted.

As is clear from the exploded perspective view of the support base in FIG. 1, rectangular through holes 15 are formed at positions corresponding to the four corners of the frame 12 provided on the rotating base 2, respectively. Spacers 16 are arranged in each of the through holes 15, as is clear from the cross-sectional views of FIGS. 2 and 3. These spacers 16 have upper ends 16a in contact with the lower surface of the curved surface 9 corresponding to the lower surface of the tilting base 3 when the support base is assembled, and lower ends 16b.
is in contact with the upper surface of the fixed base 1. Spacer 1
Reinforcing legs 17 are provided on the lower surface of the fixed base 4 against which the fixed base 4 is abutted.

As is clear from FIG. 3, the curved surface 9 has a pair of grooves 18 formed along the tilting direction. On the other hand, the upper end 16a of the spacer 16 is provided with a stepped portion 16c shaped to engage with the groove 18. Further, the spacer 16 is inserted into the through hole 15 with a sufficiently small gap and with little play. Further, the spacer 16 is formed by molding from a self-lubricating synthetic resin material such as polyacetal, which has a low coefficient of friction.

When the support base is assembled, as shown in FIGS. 2 and 3, the rotating base 2 is mounted on the fixed base 1 with the shaft 6.
It is assembled so that it rotates around the center. The rotating base 2 has a washer 1 attached to the tip of the shaft 6.
9. It is assembled with screws 20 so that it can rotate freely and cannot come off. The spacer 16 is inserted into the through hole 1 so that the upper end 16a engages with the groove 18.
It is located within 5. The tilting base 3 has a guide pin 11 inserted into the guide groove 10, and the rotating base 2
It is assembled by a washer 21 and a screw 22 attached to the tip of the guide pin 11 so as to be able to freely tilt relative to the guide pin 11 and not to separate. In the display device 4, the tilting base 3 is fixed to the bottom surface 4a with screws 14 so that the display surface 4c is tilted by the tilting of the tilting base 3.

Next, an explanation will be given of the operation of the device support stand constructed based on the above-mentioned embodiment of the present invention. Although the weight of the display device 4 is added to the tilting base 3,
This weight is transferred to the fixed base 1 via the spacer 16. When tilting the display surface 4c to a desired angle, the tilting base 3 is rotated by the rotating base 2.
On the other hand, the guide groove 10 and the guide pin 11 allow the display surface 4c to tilt only in the vertical direction when viewed from the front, that is, in the direction of arrow B. Moreover, this tilting direction is regulated by the engagement between the stepped portion 16c of the spacer 16 and the groove 18, and is also achieved by the groove 18 sliding on the upper end 16a. On the other hand, when the display surface 4c is rotated in the horizontal direction indicated by arrow A to change its orientation to an arbitrary position, the stepped portion 16c of the upper end 16a of the spacer 16 is engaged with the groove 18, so that the tilting base 3 receives horizontal force together. Then, the lower end 16b slides on the upper surface of the fixed base 1, and the rotating base 2 is rotated about the shaft 6. During this rotation, the through hole 15 and the spacer 1
6, there is little play, so the rotational movement is performed without play. Therefore, the display device 4,
That is, the display surface 4c is rotated in the direction shown by arrow A with respect to the fixed base 1. These tilting and rotation operations are performed by the operator holding and operating the display device 4 by hand. At this time,
Since the spacer 16 has a small coefficient of friction, it can be tilted and rotated smoothly.

Furthermore, the fixed base 1 receives the load from the display device 4 intensively at the part where the spacer 16 comes into contact, but since the legs 17 are provided there, the legs 17 are able to connect the table (not shown) and the fixed base 1. It is interposed between them to provide a reinforcing effect for the fixed base 1.

In the above-mentioned embodiment of the present invention, the legs 17 are provided for reinforcing the fixed base 1.
7 may be formed by integral molding with the fixed base 1, or as shown in FIG. A rib (not shown) may be formed and used as a reinforcing member.

In addition, in the above embodiment of the present invention, a case where the present invention is applied to a support stand of a display device has been described, but it goes without saying that the device to which the present invention is applied is not limited to a display device but can be applied to various other devices.

Furthermore, although the through holes 15 are arranged at the four corners of a quadrilateral as a reference, it is of course possible to use other shapes other than a quadrangle as a reference, such as a rectangle, etc. .

〔effect〕

As described above, according to the present invention, the weight of the device is not added to the rotating base, so the rotating base does not need to be made of a material that takes strength into consideration, and its wall thickness can be made thinner, requiring a large amount of material. A device support stand that is not required and has a reduced cost can be obtained. In addition, the conventional rollers for smoothing tilting movements and ring-shaped spacers for smoothing rotational movements can be replaced with spacers, reducing the number of parts and reducing costs by reducing assembly man-hours. can. Furthermore, since the spacer transfers the weight of the device to the fixed base without passing through the rotating base, even if the parts are deformed, the rotation and tilting operations will not be adversely affected and will remain stable for a long period of time. It is possible to provide a support stand for equipment that exhibits performance.
