[Conventional technology]

If the screen angle of the television receiver is constant, it may be difficult to see depending on the viewing direction. Therefore, a tilt type stand has been proposed. In such a stand, a supporting plate is arranged so as to be tiltable on a slide base. By supporting the television receiver by this supporting plate, the angle of the screen can be adjusted to an arbitrary angle. It becomes possible to do. Then, in the conventional stand, if it is adjusted to an arbitrary angle, it is fixed by a fixing means.

[Problems to be solved by the invention]

According to such a tilt stand, when the support plate is supported in a tiltable manner by the roller, the rotation of the roller tentatively regulates the tilt direction, but reliable guidance cannot be achieved only by guiding the roller. .
Further, when the support plate supported so as to be tiltable falls off from the slide base, the tilt stand is separated, which may cause the supported television receiver to drop.

The present invention has been made in view of the above problems, and reliably guides the support plate mounted on the slide base in the tilt direction, and prevents the support plate from falling off the slide base. It is intended to provide a tilting stand.

[Means for solving problems]

According to the present invention, a plurality of rollers are arranged so as to be rotatable about an axis parallel to a generatrix of an arcuate recess formed on the upper surface of a slide base so as to project onto the upper surface of the arcuate recess, and the arcuate recess is provided. A support plate, which is formed so as to correspond to the above, and has an arcuate convex portion on the lower surface, which is supported by the roller, is placed on the slide base in a tiltable manner through the roller in the circumferential direction of the arcuate concave portion. , A guide having a rectangular cross section in which the dimension of the support plate in the tilt direction is long is projected on the slide base, and a concave portion is formed on the upper surface of the support plate so as to extend in the tilt direction of the support plate in an open state, A groove for guiding the side surface in the direction of the length of a guide projecting on the slide base is provided, extending in the tilt direction of the support plate so as to penetrate the support plate from the bottom surface of the recess and open to the lower surface thereof. A tilt stand in which a holding block having a dimension in a direction larger than a widthwise dimension of a groove of a support plate is fixed to an upper part of a guide in a state of being depressed in a recess without protruding from an upper surface of the support plate. It is a thing.

[Action]

For example, a television receiver is fixedly arranged on the support plate,
By pressing the support plate in the circumferential direction of the arcuate recess formed on the upper surface of the slide base, the support plate is circled with the arcuate recess on the lower surface thereof being supported by the rollers on the slide base. It is tilted in the circumferential direction of the arcuate recess, which makes it possible to adjust the screen angle of the television receiver. During such a tilting operation, the guide projectingly provided on the slide base relatively moves in the groove of the support plate in the length direction thereof. Then, the support block fixed to the upper part of the guide prevents the support plate from falling off the slide base.

The present invention will be described below with reference to an embodiment shown in the drawings. Fig. 1 ~
As shown in FIG. 3, the tilt stand according to this embodiment includes a bottom plate 10. A center spindle 11 is planted approximately in the center of the bottom plate 10, and the center spindle 11
A rolling ball 12 is arranged around the. As a result, the slide base 13 on the bottom plate 10 becomes the center spindle.
It is rotatably supported around 11. An arcuate recess 14 is formed on the upper surface of the slide base 13. Further, a concave portion 15 is formed on the concave portion 14 at the corner portion thereof, and a roller 16 is rotatably arranged. A support plate 17 whose lower surface is an arcuate recess is placed on the arcuate recess 14 of the slide base 13 via these rollers 16 and supported so as to be tiltable.

A pair of left and right protruding guides 18 are provided on the recess 14 on the upper surface of the slide base 13. These guides 18
Are engaged with the grooves 20 of the recesses 19 formed on both sides of the support plate 17. Further, as shown in FIG. 1, a holding block 21 is attached from the upper side of the support plate 17 and is connected to the guide 18 by screws. The blocks 21 prevent the support plate 17 from falling off the slide base 13.

A lock lever 25 is arranged on the slide base 13 and is rotatably supported by a screw 26 that constitutes a fulcrum pin. A long hole 27 is formed in the lock lever 25, and a screw 28 planted in the slide base 13 is inserted therethrough. As a result, the rotation angle of the lock lever 25 is regulated. Further, the lock lever 25 has a bending piece 29. The lever 25 also has a protrusion on its side.
30 is formed and protrudes from the opening 32 of the side wall 31 of the slide base 13, and a knob 33 is attached to the tip of the protrusion 30. On the other hand, a locking plate 34 is fixed to the lower surface of the support plate 17, and a serrated locking portion 35 is formed on the side surface side thereof.

In the above structure, the slide base 13 is rotated about the center spindle 11 by the rolling balls 12, and the direction of the screen of the television receiver supported by this stand is changed. It can be changed. Further, the support plate 17 is tilted on the slide base 13 by the rollers 16, and thereby the angle of the screen of the television receiver supported by the support plate 17 is tiltable.
Therefore, the angle of the screen of the television receiver can be adjusted to the optimum angle.

When performing the tilting operation as described above, the lock lever 25 is rotated clockwise about the screw 26 as shown by the chain line in FIG. This makes lever 25
Since the bent piece 29 is separated from the locking portion 35 of the locking plate 34, the support plate 17 can freely tilt on the slide base 13. When the desired angle is adjusted, the lock lever 25 is rotated counterclockwise by the knob 33 in this state as shown by the solid line in FIG.
The bent piece 29 is locked by locking the locking portion 35 of the locking plate 34. The lock lever 25 is urged to rotate counterclockwise and clockwise by a toggle spring 36 in the locked position and the unlocked position, respectively.

According to such a tilt stand, the guide in the tilt direction of the support plate 17, which is supported by the roller 16 on the slide base 13 so as to be tiltable, is provided by the protruding guide 18 and the groove 20 formed on the base 13. It becomes possible to perform surely, and the reliable tilting operation comes to be performed. Moreover, in the guide 18 that penetrates the groove 20 of the support plate 17,
The pressing block 21 is attached from above the concave portion 19 of the supporting plate 17, so that the supporting plate 17 is prevented from falling off the slide base 13. As a result, the tilt stand is not separated, and the television receiver supported on the support plate 17 can be stably supported.

〔The invention's effect〕

As described above, the present invention arranges a plurality of rollers so as to rotatably project around the axis line parallel to the generatrix of the arcuate concave portion formed on the upper surface of the slide base, to the upper surface of the arcuate concave portion, A support plate, which is formed so as to correspond to the arcuate recess and has an arcuate recess on the lower surface that is supported by a roller, can be tilted on the slide base in the circumferential direction of the arcuate recess via the roller. Place the guide on the slide base with a rectangular cross-section that has a long dimension in the tilt direction of the support plate, and make a recess on the upper surface of the support plate to extend in the tilt direction of the support plate. The guide plate is formed from the bottom surface of the recess to extend in the tilt direction of the support plate so as to penetrate the support plate and open to the lower surface thereof, and guides the long side surface of the guide projecting on the slide base. Provide a groove, and fix the presser block whose width dimension is larger than the width dimension of the groove of the support plate to the upper part of the guide in the recess without protruding from the upper surface of the support plate. The tilt stand.

Therefore, according to the present invention, the support plate movably supported in the tilt direction by the plurality of rollers provided on the upper surface of the slide base is secured in the tilt direction by the guide engaged with the groove of the support plate. It will be possible to guide you to. Therefore, the roller and the guide can correctly tilt the support plate with respect to the circumferential direction of the arcuate recess formed on the upper surface of the slide base.

The guide, which is designed to be engaged with the groove of the support plate, has a rectangular cross section, and the long side surface of the guide is guided by the groove. It is possible to reliably prevent the wobbling, and it is possible to achieve a more stable tilt operation.

In addition, the holding block having a widthwise dimension larger than the widthwise dimension of the groove of the support plate is fixed to the upper end of the guide in a state of being depressed in the recess without protruding from the upper surface of the support plate. Therefore, it becomes possible to reliably prevent the supporting plate from falling off the slide base by such a pressing block. That is, it is possible to prevent the support plate from coming off from the slide base by the guide that also serves as the guide means in the tilt direction.

Since the pressing block is attached to the guide in a state that it is not protruded from the upper surface of the support plate but is recessed in the concave portion, the pressing block does not protrude to the upper surface of the support plate, and thus the television block is mounted on the support plate. The press block does not get in the way when the John receiver is mounted, and the television receiver can be supported on it stably and surely.
