Benefits of technology

[0008] A further object of the invention is to provide a stepless height adjusting apparatus that can be readily disassembled.

Problems solved by technology

Once the coil spring 300′ is subject to elastic fatigue, or the friction between the slider 100′ and the sliding sleeve 210′ changes, it is difficult to achieve a balance of the forces to maintain the height of the thin display apparatus.
Moreover, a replacement of the coil spring 300′ is time-consuming and inconvenient.

Embodiment Construction

[0017] As shown in FIG. 2, a disclosed stepless height adjusting apparatus includes a slider 100, a slide way 200, and an elastic supporting device 300.

[0018] The slider 100 is an axially symmetric bar. A cross section of the bar in a top portion is larger than a cross section of the bar in the bottom portion so as to form an incline on a side surface of the slider 100, and the cross sections are perpendicular to an axis of the slider. The side surface of the slider 100 is thus an incline surface from the top portion to the bottom portion of the slider 100. The slider 100 contains a coupling base 120 for coupling to a device, such as a thin display apparatus. The height of the device is adjusted by the stepless height adjusting apparatus.

[0019] The slide way 200 is coupled to the slider 100 for moving thereon. The slide way 200 contains a sliding sleeve 210 between the slide way 200 and the slider 100 for the slider 100 to move smoothly.

[0020] The elastic supporting device 300 is...

Abstract

A stepless height adjusting apparatus includes a slider, a slide way, and an elastic supporting device. The slider is an axial symmetry bar. The axial symmetry bar has a larger cross section perpendicular to the axis thereof on the top portion and a smaller cross section perpendicular to the axis thereof on the bottom portion so as to form an incline on the side surface. The slider couples to the slide way to move on the slide way. The elastic supporting device is disposed on the top portion of the slide way to support the slider with balance forces between the elastic supporting device and the incline of the slider. When an external force is pushing the slider, the slider may move along the slide way. When the external force is removed, the slider may stop at a determined position on the slide way by the balance force.

Description

RELATED APPLICATIONS [0001] The present application is based on, and claims priority from, Taiwan Application Serial Number 94102375, filed Jan. 26, 2005, the disclosure of which is hereby incorporated by reference herein in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates to a height adjusting apparatus and, in particular, to a stepless height adjusting apparatus. [0004] 2. Related Art [0005] As shown in FIG. 1, a conventional height adjusting device of a thin display apparatus is comprised of a slider 100′, a slide way 200′, a coil spring 300′ and a base 500′. The thin display apparatus is installed on a coupling portion 120′ of the slider 100′. A user imposes a force on the thin display apparatus to adjust the height of the thin display apparatus. After the force is removed, a weight of the thin display apparatus and the slider 100′ is equal to a sum of an elastic force of the coil spring 300′ and a friction between the slide...
