  As described above, the support device 3 is composed of only three parts, that is, the support leg part 21 made of synthetic resin, the base 22, and the cover part 23, and neither a screw nor a metal part is used. In addition, the support legs 21 are integral with the rear cover 13 of the display 2, and there are only two base parts 22 and a cover part 23 as dedicated parts for support.

  Next, a method for assembling the support device 3 will be described.

  In FIG. 4, the shaft portion 33 of the support leg 21 is inserted into the shaft support portion 44 of the base 22, and the friction plate 34 is inserted into the gap KG while bending the bending portion 32 by pressing downward, and the arm portion. 31 is fitted into the notches 42a and 43a. As a result, the surface of the friction plate 34 is urged and pressed against the back surface of the holding plate 42 by the elastic force of the bending portion 32, that is, the stress generated inside the bending portion 32. Then, the cover portion 23 is covered from the front side of the holding portion 22a, and the claws 541, 541 are fitted into the locking holes 424, 424, while the edge portion 54 is expanded. Thereby, the support device 3 is completed.

  Next, the usage method of the support apparatus 3 is demonstrated.

  The friction plate 34 is pressed against the holding plate 42 with a predetermined urging force, and torque is generated by the frictional force or engagement force generated by the pressing. When the user of the display device 1 applies a force in the direction of tilting with the display 2, the friction plate 34 and the holding plate 42 slide relative to each other, and the display 2 can be tilted to a desired angle. At that time, the display 2 may be tilted while being lightly pushed downward.

  The tilt angle of the display 2 is a range in which the arm portion 31 can move within the cutout portion 42a. That is, when the arm portion 31 comes into contact with the cover portion 23 on the front side and the arm portion 31 comes into contact with the back end of the notch portion 42a on the rear side, the respective movements are restricted, and during this time, the tilt angle is adjusted. The adjustment range. When it is desired to narrow the adjustment range of the tilt angle, the adjustment member 45 is attached to the holding plate 42 as shown in FIG. If a plurality of attachment holes 423 are provided at different positions in the longitudinal direction of the notch portion 42a, the attachment position of the adjustment member 45 can be adjusted, and the adjustment range of the tilt angle can be variously changed. .

  Grooves 341 and 421 are provided on the contact surface of the friction plate 34 and the holding plate 42. Since the engaging force is applied when the grooves 341 and 421 are engaged, the tilt holding angle is stabilized. However, the torque may be generated only by the planar frictional force of the contact surface between the friction plate 34 and the holding plate 42 without providing the grooves 341 and 421. In that case, stepless angular position adjustment is possible.

  Even when the display 2 is strongly pressed downward, the friction plate 34 is held by the receiving plate 43 and is stable, and the user's operational feeling is also good. Further, the presence of the stopper 35 prevents the bending portion 32 from being excessively bent and destroyed. In addition, since both the receiving plate 43 and the stopper 35 can stabilize the support device 3 against an excessive force from the outside and prevent destruction, either one of them may be omitted.

  Thus, according to the support device 3 of the present embodiment, the support leg portion 21, the base 22, and the cover portion 23 are all formed by molding synthetic resin, have a small number of parts, and are easy to assemble. Is advantageous.

  In the support device 3 of the above embodiment, the shaft portion 33 of the support leg 21 protrudes left and right. However, the width dimension of the bending portion 32 is widened and the shaft is formed at the center of the bending portion 32 as follows. It is good also as a form which provides the part 33. FIG.

  FIG. 8 is a perspective view showing a modified example of the support leg 21B.

  As shown in FIG. 8, the support leg portion 21B includes an arm portion 31B, a curved portion 32B, and a shaft portion 33B. The shaft portion 33B is provided at the center in the width direction at the lower end portion of the bending portion 32B. In this case, one shaft support portion 44B is provided on the substrate 41B. In this way, the overall width dimension of the support leg 21B can be increased, which is advantageous in terms of strength.

  In the embodiment described above, the resin film 342 is not required when the holding plate 42 and the friction plate 34 have sufficient wear resistance. In order to fix the cover portion 23 to the holding portion 22a, other various structures may be employed. It is also possible to fix using screws. The shaft portions 33 and 33B of the support leg portions 21 and 21B are made of synthetic resin, but a metal rod may be used. In that case, it can be integrated by insert molding at the time of molding of the support leg 21. Although the support leg portion 21 is formed integrally with the rear cover 13 of the display 2, it may be formed separately and connected to each other using screws or the like.

In addition, the structure, shape, dimensions, number, material, and the like of the entire support device 3 and display device 1 or each part can be appropriately changed in accordance with the spirit of the present invention.
