ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a slidable seat with brake device, and more particularly to a slidable seat including a base seat and a brake member disposed at bottom end of the base seat. In normal state, the brake member is pressed against a desk face to prevent the base seat from freely sliding. A linking device is operable to lift the brake member and make the brake member leave the desk face. At this time, an article such as a display supported on the base seat can be freely slided and displaced on the desk face along with the base seat.
The picture tube-type display applied to a computer in early time has large volume and heavy weight. Such display has been replaced by plasma or liquid crystal display which has light weight and small volume. In general, a user often positions the display on a corner of a desk to reduce the room occupied by the display. However, when such positioned, in use of the computer, the user must see the display obliquely. This fails to meet the human configuration. Therefore, when using a light and small plasma or liquid crystal display, some users will move the display to the center of the desk face for facilitating use. However, each time using the display, the user must move and displace the display. This is quite inconvenient to the user.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a slidable seat with brake device. The slidable seat includes a base seat slidable over a plane face such a desk face. A brake device is additionally disposed at bottom end of the base seat. When it is desired to move the slidable seat, the user can make the brake device leave the plane face. At this time, the slidable seat can be freely pushed or pulled to slide over the plane face. After the slidable seat is moved to a desired position, the brake device is tightly pressed against the plane face so as to stably locate the slidable seat at the desired position.
According to the above object, the slidable seat with brake device of the present invention includes: a base seat including a board section, multiple sliding members being mounted on the bottom side of the board section for sliding over a desk face, the bottom end of the board section being formed with a chamber; a brake member including a main body snugly disposed in the chamber of the bottom end of the base seat, the bottom end of the main body being connected with a brake block; and a linking device including an operating member disposed between the base seat and the brake member, in normal state, the operating member downward pressing the brake member to make the brake block tightly attach to the desk face and prevent the base seat from freely sliding, the operating member being operable to lift the brake member, whereby the brake block no more tightly attaches to the desk face and the base seat can be freely slided and displaced over the desk face by means of the sliding members so as to shift an article such as a display supported on the board section of the base seat.
In the slidable seat with brake device of the present invention, the linking device includes an operating member. A middle section of the operating member is pivotally mounted on the base seat. A first end of the operating member is pivotally connected with an upper face of the main body of the brake member. A spring in normal state is compressed between a second end of the operating member and the base seat for urging the first end to resiliently downward push the brake member to make the brake block on bottom end thereof tightly attach to the desk face and prevent the base seat from sliding thereover.
In the slidable seat with brake device of the present invention, the brake member is fitted in the chamber of the base seat and hooked by at least one restricting hook arm extending from the base seat so that the brake member is stopped from slipping outward. The linking device includes an operating member slidably positioned in a slide cavity of the base seat. A lateral wall of the operating member is formed with at least one oblique recess in which a projecting shaft disposed on lateral wall of the brake member is slidably fitted for drivingly lifting the brake member. A handle section upward projects from the front end of the operating member. A compression spring is compressed between the chamber and the brake member. In normal state, the compression spring downward resiliently presses the brake member to make the brake block on the bottom end thereof tightly attach to the desk face and prevent the base seat from sliding over the desk face. A restoring spring is compressed between the slide cavity of the base seat and an inner side of the operating member. In normal state, the restoring spring backward resiliently pushes the operating member to make the oblique recesses not upward drive the projecting shaft of the brake member, that is, not lift the brake member so that the brake block will still tightly attach to the desk face to prevent the base seat from sliding.
