Abstract

PROBLEM TO BE SOLVED: To enable a tilting leg to be quickly retracted or extended. SOLUTION: A tilting leg 2 is provided to the base 1a of an equipment main body case 1 to regulate the case 1 in tilt angle. A holding part 3 where the threaded part 2a of the tilting leg 2 is screwed is longitudinally divided in two split parts 3a and 3b, and a support point 3c is provided to each lateral edge of the holding part 3 to enable the split parts 3a and 3b to open or close like scissors. A coil spring 6 is provided to the open end of the holding part 3 to energize the split parts 3a and 3b in a closing direction, so that threaded part 2a of the leg 2 is held by the split part 3a and 3b which are normally closed. A press button 4 which is pressed in from the outside of the support point 3c to energize the holding part 3 in an opening direction is provided outside the support point 3c, and the press button 4 is pressed inward to open the split parts 3a and 3b of the holding part 3 which are opened or closed like scissors. The button 4 is pressed to enable the split parts 3a and 3b to release the leg 2, whereby the leg 2 can be freely moved in or out.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilt foot structure which allows a tilt foot for adjusting a tilt angle of a liquid crystal projector or the like to be quickly taken in and out.

[0002]

2. Description of the Related Art A tilt foot, which is disposed at the bottom of a main body of a device such as a liquid crystal projector or a measuring instrument and adjusts a tilt angle when the main body is installed on a desk or the like, is generally formed by a screw rod which forms an upper portion of the tilt foot. The tilt foot is inserted and removed by rotating and screwing the unit into the bottom of the device body. However, when the tilt foot is extended or stored, the tilt foot has to be rotated many times, which requires time and labor.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a tilt foot structure which allows quick access to the tilt foot.

[0004]

SUMMARY OF THE INVENTION An upper portion of a tilt foot is provided in a tilt foot structure which is disposed at the bottom of a liquid crystal projector or the like and adjusts a tilt angle of the device main body when the device main body is installed on a desk or the like. A screw portion, a holding portion which is opened and closed in a scissor-like manner with a fulcrum provided at a lateral end portion of the split portion, which is divided into two in a vertical direction for screwing and holding the screw portion, and provided at an open end of the holding portion. It has a helical spring that urges the split part in the closing direction, and a push button that pushes in from the outside of the fulcrum to urge the holding part in the opening direction, and releases the tilt foot by pushing in the push button and opening the holding part. A structure that can be freely inserted and removed from the bottom of the equipment body.

[0005] At the outer end of the push button, there is provided a cap which also serves as a stopper for releasing and stopping the holding portion when pushed in.

[0006] A spring is provided between the tip of the screw portion constituting the upper portion of the tilt foot and the holding portion, and when the push button is pushed in to release the tilt foot, the tilt foot is automatically moved to the bottom of the device body. To be stored.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a (A) side view of a tilt foot portion showing one embodiment of a tilt foot structure according to the present invention;
(B) It is a top view, (C) It is a top view at the time of release. The tilt foot 2 is attached to the bottom 1a of the housing 1 of the device body such as a liquid crystal projector.
, And when the device main body is installed on a desk or the like, the tilt foot 2 is rotated to form a screw rod 2 that constitutes an upper portion of the tilt foot 2.
a is put in and out of the bottom of the housing 1 to adjust the tilt angle of the device body. The holding part 3 for screwing and holding the screw rod part 2a of the tilt foot 2 is divided into two parts in the vertical direction and divided into two divided parts 3a, 3a.
b. A fulcrum 3c is provided at the lateral end of each of the divisions 3a and 3b so that the divisions 3a and 3b open and close like scissors. A helical spring 6 is attached to the open end of the holding section 3 to urge the split sections 3a and 3b in the closing direction. Normally, the split sections 3a and 3b are closed and the screw section 2a of the tilt foot 2 is held. . A push button 4 is provided outside the fulcrum 3c of the holding part 3 to push the holding part from the outside of the fulcrum to urge the holding part in the opening direction. Then, as shown in the figure, when the push button 4 is pushed in, the divisions 3a, 3a, 3
Open b. When the tilt foot 2 is to be taken in and out largely, the push button 4 is pushed in to release the divisions 3a and 3b of the holding part 3 so that the tilt foot 2 can be freely taken in and out of the bottom of the device body.

FIG. 2 is a side view of a tilt foot portion showing another embodiment of the tilt foot structure according to the present invention. At the outer end of the push button 4, there is provided a cap 5 which also serves as a stopper for releasing and stopping the holding portion 3 when pushed. A spring 7 is provided between the tip of the threaded rod portion 2 a constituting the upper part of the tilt foot 2 and the holding portion 3, and a push button 4 is provided.
When the tilt foot 2 is released by pushing in, the tilt foot 2 is automatically stored in the bottom 1a of the device main body.

[0009]

According to the present invention, it is arranged at the bottom of a liquid crystal projector or the like.
In a tilt foot structure for adjusting a tilt angle of a device main body when the device main body is installed on a desk or the like, a screw portion forming an upper portion of the tilt foot and a vertical portion for screwing and holding the screw portion are divided into two parts. Holder that opens and closes in the form of scissors with a fulcrum attached to the lateral end of the split part, a helical spring that urges the split part attached to the open end of the holder in the closing direction, and pushes in from the outside of the fulcrum to hold it A push button that urges the part in the opening direction,
By pressing the push button to open the holding portion, the tilt foot is released and the tilt foot can be freely inserted into and removed from the bottom of the device main body, thereby obtaining a tilt foot structure that can be quickly inserted and removed.
