Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilt foot mechanism which can be folded and stored and is used for height adjustment or tilt adjustment of electronic equipment or the like.

[0002]

2. Description of the Related Art Conventionally, a tilt foot mechanism of this type is provided with a tilt foot on the bottom surface of a device body, and the tilt foot is rotated substantially 90 degrees from the stored position which is substantially parallel to the device body. It is rotatable between a set position and the tilt foot from the stored position to the set position to adjust the height or inclination of the device body. The holding of the tilt foot at the set position is performed by the weight of the device to which the tilt foot is attached.

[0003]

Therefore, the device body holding the tilt foot in the set position can sufficiently withstand the force from the upper direction, but cannot withstand the force from the lateral direction. The tilt foot could be folded into the stowed position if it could not withstand enough and a lateral force was applied, which was a big problem in using the device.

Therefore, in order to make it difficult to fold the tilt foot to the storage position, it may be considered that the tilt foot is held at the set position by the biasing force of the spring. However, there is a problem that the assembly becomes complicated and parts other than the tilt foot are required.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks and to reliably position the tilt foot from one of the stored position and the set position to the other by a click operation with a simple structure.

Another object of the present invention is to provide a tilt foot mechanism which can sufficiently hold a tilt foot in a set position and can withstand a lateral force sufficiently. .

Still another object of the present invention is to provide a tilt foot mechanism which can hold the tilt foot in the set position in a duplicated manner and can easily return to the stored position.

[0008]

In order to achieve the above object, the present invention provides a tilt foot on the bottom surface of the device body,
In a tilt foot mechanism for adjusting the height or tilt of the device body by rotating the tilt foot from the storage position to the set position, a shaft hole of a rotation shaft for rotating the tilt foot is formed into an elongated hole. To form
A click portion is provided on the periphery of the rotation portion of the tilt foot, and the rotation of the tilt foot causes the click portion to come into contact with the bottom surface of the main body of the device to bend the tilt foot. A shaft slides in the elongated hole to position the tilt foot at the storage position or the setting position.

Further, according to the present invention, when the tilt foot is at the set position, the pivot shaft is located at one end side of the elongated hole, the click portion comes into contact with the stopper protrusion, and the tilt foot is pivoted. It is to prevent.

Further, according to the present invention, when the tilt foot is rotated from the set position to the storage position, the rotation shaft is slid to the other end side of the elongated hole to bend the tilt foot. Due to the bending, the rotating shaft slides in the elongated hole.

[0011]

When the tilt foot is rotated from one of the stored position and the set position to the other, the click portion comes into contact with the bottom surface of the device body by the rotation of the tilt foot to bend the tilt foot. The rotation shaft slides in the elongated hole due to the flexure, and the tilt foot is positioned at the storage position or the setting position by a click operation. Then, when the tilt foot is in the set position, the rotation shaft is located at one end side of the elongated hole and the click portion abuts the stopper protrusion, and an external force is applied to return the tilt foot to the storage position. Even so, the tilt foot is prevented from rotating by the click portion and the stopper protrusion.
