A through hole 7 for inserting a screw is formed in the center of the protrusion 6.

Reference numeral 8 denotes a monitor stand connected to a display monitor (not shown); FIG. 3 shows its top surface, and FIG. 3B shows its bottom surface. The left and right ends of the lower sliding bottom of the monitor stand 8 are in contact with the left and right ends of the sliding parts 5c and 6d of the rotating stand 4, and the monitor stand 8 is slid forward and backward as indicated by the arrow, that is, tilted. Sliding surfaces 91 and 9b having a constant width are integrally formed in a curved shape.

Reference numeral 10 denotes an upper sliding surface integrally formed at the center of the upper surface of the monitor stand 8. At the center of the upper sliding surface 10, a protrusion 6 is provided in the front-rear direction.
A long hole 11 is made to allow movement. 10a
, 10t) are regulating walls formed at both ends of the upper sliding surface 10, and regulate the rotational direction of the monitor stand 8 by sliding with the left and right side surfaces of the tip of the post, which will be described later.

Reference numeral 12 indicates ventilation holes provided at eight locations in total at the center of the sliding bottom of the lower surface of the monitor stand 8; reference numeral 13 indicates ventilation holes provided near the left and right edges and back edge of the monitor stand 8; 92
L, 9t) and the sliding parts 5C, 5d, the ventilation hole 13 directly dissipates the heat generated by the monitor display to the outside of the housing.

Reference numeral 14 denotes a T-shaped post that is attached to the tip of the protrusion 6 through the through hole 7. The post 14 is supported by the support portion 6a of the protrusion 6, and the lower surface of the tip of the post 14 slides against the monitor stand 8. A moving surface 6bf is formed. In addition, there is a coupling hole 6C with a screw 16 in the center of the post 14, and after overlapping the pedestal 1, rotation table 4, and monitor table 8, a compression coil spring 16 is attached to the support part 6a of the rotation table 4. The post 14 is inserted, and the screw 16 is tightened while holding it down with a washer 17 to join.

18 to 21 are joint bosses for joining display monitors, which are tightened from the bottom surface of the monitor stand 8 via screws or the like.

Reference numerals 22 and 23 indicate adjustment bosses for adjusting the rotation angle provided near the front and rear ends of the elongated hole 11, and the rotation angle of the monitor stand 8 is adjusted by fixing the adjustment fittings 24 here with screws 25 or the like. As shown in Fig. 2, if the metal fittings 24 are attached to the two total adjustment bosses 22 and 23, the aperture angle formed by the elongated hole 11 of the monitor stand 8 can be set to β, and there are only 31 positions. When attached, it is possible to widen the aperture angle to γ, which is wider than β. Incidentally, an arbitrary opening angle can be obtained by preparing several types of metal fittings with different lengths.

The most important feature of this embodiment is that the pedestal 1, rotation pedestal 4, and monitor pedestal 8 are all made of the same material, that is, styrene copolymer (for example, IM-15 manufactured by Asahi Kasei Corporation), and are all integrally molded. As shown in FIG. 4, the material has properties that cannot be obtained with conventional human BS resins, that is, a good balance between toughness and rigidity, and good abrasion resistance and weather resistance.

The operation of the turntable device of this embodiment configured as described above will be described below.

First, the pedestal 1 is stably placed in contact with the floor surface, and the rotation table 4 on the top thereof rotates in the horizontal direction about the center of the pedestal 1 as a fulcrum. Therefore, the display monitor can be rotated freely in the horizontal direction.

Next, the monitor stand 8 rotates along the curved surfaces of the sliding surfaces 9L and 9b provided at the left and right ends of the T-plane sliding bottom in the direction of the arrow, that is, back and forth when viewed from the screen of the display monitor, as shown in FIG. Since the monitor stands 8F and 8B can be moved back and forth to the maximum extent indicated by the two-dot chain lines, the orientation of the display monitor can also be rotated in the vertical direction. This rotation angle or movement range can be freely adjusted using metal fittings 24 for adjusting various lengths.

The post 14 is located in the center of the rotary table device, and has an upper sliding surface 142L and a washer 17 attached via a compression coil spring 16. It is tightened with 15. Therefore, the sliding surface 91L of the monitor stand 8.

9b, the upper surface of the sliding portion 6c and sa, the lower sliding surface 142L of the post 14, and the upper sliding surface 1o of the monitor stand 8 slide while being in pressure contact with each other.

Note that the sizes of the monitor stand 8 and the stand 1 are adjusted according to the size of the display monitor, but the larger the size of the monitor stand 8, the more the stability of the entire device is impaired. The frame also tends to become larger. In addition, during assembly, the display monitor must be further joined to the monitor stand 8 after the monitor stand 8, pedestal 1, and rotating stand 4 are all assembled, making it difficult to manufacture a small and stable rotating stand device. In this embodiment, if the monitor stand s'lsx is positioned as shown in FIG. You can connect it to a display monitor using a screwdriver etc. In addition, when joining via the joining boss 18° 20, the monitor stand 8 may be placed in the position 8B shown in Fig. 2, and the monitor stand 8 may be rotated appropriately so that it is in a predetermined position where it can be joined. .

As described above, according to this embodiment, since the pedestal 1, rotating table 4, and monitor table 8 are made of styrene-based copolymer, only one type of molding material is required, and there is no need to change the material during molding. , there is no need to match the color tone. In addition, styrene-based copolymers have a better balance between toughness and rigidity than the conventionally used BS resin, and are resistant to impact, making equipment more reliable than when pasted with other materials, and providing sufficient resistance to rotational movements. Since it has sufficient wear resistance and weather resistance, there is no need to attach any special material to the sliding surface.

Effects of the Invention As described above, according to the present invention, there is provided a monitor stand, a rotating stand that is slidably held so that the monitor stand can be rotated in a vertical direction, and a rotating stand that is slidably held so that the monitor stand can be rotated in a horizontal direction. Since the pedestal, which can be slidably held, is made of a styrene copolymer, only one type of molding material is required, there is no need to change the material during molding, and there is no need to match the color tone. In addition, compared to conventional ABS resin, it has a better balance of toughness and rigidity, making it more resistant to impact, making the device more reliable than when pasted with other materials, and providing sufficient durability to withstand rotational motion. Because it is abrasion resistant and weather resistant, there is no need to attach other materials to improve sliding on the sliding surfaces between the monitor stand and rotating stand, and between the rotating stand and mount. , its practical value is significant.
