DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing angle adjusting device for adjusting the angle of a housing such as a television receiver or a display device. The present invention relates to a housing angle adjusting device capable of fixing a housing at an angle of.

[0002]

2. Description of the Related Art As shown in FIG. 6, a conventional device is a television receiver or a display as a housing, which comprises a swinging member 1 and a pedestal 3 which supports the swinging member 1 so as to be able to swing. The structure was attached to the bottom 2 of the device. And
The angle adjustment of the television receiver or the display device is performed by an adjuster applying an external force (hereinafter, referred to as an operating force) and turning the television receiver or the display device up or down with respect to the pedestal 3 in the horizontal direction. The fixed angle is adjusted by the frictional force acting between the swing member 2 and the pedestal 3. Incidentally, a device related to this type of device is described in Japanese Utility Model Laid-Open No. 63-156170.

[0003]

In the above prior art, the angle is fixed by the position of the center of gravity of the television receiver and the display device, and the frictional force smaller than the operating force and larger than the force by which the set is inclined by its own weight. I was For this reason, it is difficult to adjust the position of the center of gravity due to variations in the product, and the frictional force must be a constant frictional force smaller than the operating force and larger than the force of the set trying to tilt by its own weight. It was difficult to set the frictional force, maintain a constant frictional force, and maintain a state of being inclined at a constant angle.

An object of the present invention is to set a television at an arbitrary angle regardless of the position of the center of gravity of a television receiver and a display device, and the frictional force between a swinging member and a pedestal that swingably supports the swinging member. An object of the present invention is to provide an angle adjusting device capable of fixing a receiver and a display device.

[0005]

In order to achieve the above object, a rotating shaft and a lever rotating about the rotating shaft are provided in a hemispherical swinging member that matches the center of the bottom of the housing.
A horizontally rotatable stopper mounted on the lever in a point-symmetrical manner about a rotation axis, and the rotatable stopper is sandwiched between semi-circular grooves provided on the swinging member and the bottom side surface of the housing. I tried to insert it.

[0006]

When the television receiver or display device is swung and the position is fixed at an arbitrary angle, the lever can be moved to the left or right in the horizontal direction, so that the rotatable stopper can be rotated by the swing member and the semicircle between the bottom of the receiver. Since it is sandwiched between the grooves, it performs linear motion, and the stopper comes in and out of the hemispherical rocking member, and when this stopper protrudes from the rocking member on the hemisphere, it contacts the inner wall of the pedestal and fixes it. Can be.

Therefore, the television receiver or the display device can be easily fixed at an arbitrary angle regardless of the position of the center of gravity of the television receiver or the display device and the frictional force. Further, when the lever is fixed at an arbitrary angle, the lever is caught by the projection provided in the long hole of the swinging member, and the fixing does not come off.

[0008]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing an angle adjusting device as one embodiment of the present invention, and FIG. 2 is a front view of the angle adjusting device shown in FIG.

The hemispherical swinging member 1 is fixed to the bottom 2 of the television receiver or display device, and is mounted on the hemispherical portion of the pedestal 3. Further, the rotating shaft 7 penetrates the hemispherical swing member 1 and is attached to the bottom 2 and the pedestal 3 of the television receiver or the display device by rivets 6. Inside the hemispherical rocking member 1, a lever 4 is attached to a rotating shaft 7, and one end of the lever 4 is inserted into a long hole 10 between the rocking member 1 and the bottom 2 of the television receiver or the display device. And can be easily rotated. One end of a stopper 5 is rotatably attached to the lever 4, and the other end is inserted into a semicircular groove 9 between the swinging member 1 and the bottom 2 of the television receiver or the display device. I have.

FIGS. 3 and 4 are cross-sectional views showing cross sections taken along the line AA in FIG. As shown in FIG. 3, when the lever 4 is turned to the right, the stopper 5 is housed in the hemispherical swing member 1, so that the television receiver or the display device can swing.

Further, as shown in FIG. 4, when the lever 4 is turned to the left, the stopper 5 performs a linear motion because the other end is sandwiched by the semicircular groove 9, so that the hemispherical swing member 1 is moved.
Protrude from inside. Since the other end of the stopper 5 contacts the inner wall of the base 3, the movement of the television receiver or the display device is fixed at an arbitrary angle. At this time, the lever 4 is hooked on the projection 8 provided in the elongated hole 10 of the swing member 1, and the fixing is not released.

FIG. 5 is a side view showing the angle adjusting device of FIG. 1 partially cut away. As shown in FIG. 5, when the television receiver or the display device is tilted, the lever 4
Also tilts in synchronization with the movement of the television receiver or the display device, but since the groove 3 is provided in the base 3, the movement of the television receiver or the display device is not blocked. In addition, since the stopper 5 is located at a position deeper than the moving amount of the inclination of the television receiver or the display device,
There is no deviation from the pedestal 3.

[0013]

According to the present invention, a television receiver can be received at an arbitrary angle regardless of the position of the center of gravity of a television receiver or a display device, and the frictional force of a swinging member and a base that swingably supports the swinging member. Machine or display device can be easily fixed. Further, since the angle can be fixed without being affected by the position of the center of gravity and the frictional force, the adjustment of the position of the center of gravity and the setting and adjustment of the frictional force are not required.
