Abstract

A positionable lift stand includes a support structure defining a first positioning hole, a sliding member slidably engaged with the support structure and defines a second positioning hole, an elastic member, and a fixing member. The elastic member is connected between the support structure and the sliding member, while provides a restoring force enabling the sliding member to move against the support structure. The fixing member passes through the first positioning hole of the support structure and the second positioning hole of the sliding member. By utilizing the fixing member and various positioning holes associated with the lift stand, the lift stand can be fixedly held to occupy the least amount of space for packaging or storing purpose. Such attribute is achieved by using fewer parts and processing steps, which means fewer parts need to be manufactured, more cost savings, and less assembling time.

First claim

What is claimed is:

1. A positionable lift stand, comprising:
a support structure having a first positioning hole;
a sliding member slidably connected with the support structure and includes a main body, a fixing block and a second positioning hole, the fixing block secured to the main body and the second positioning hole is formed on the fixing block;
an elastic member connected between the support structure and the sliding member, the elastic member providing a restoring force to move the sliding member relative to the support structure; and
a fixing member having a flexible arm, a restricting protrusion formed on one end of the flexible arm, and an arc-shaped pressing portion formed on another end of the flexible arm opposite of the restricting protrusion, the fixing member further having a curled portion integrally formed on a side of the fixing member opposite the flexible arm and near the one end near the restricting protrusion, wherein the curled portion terminates at a tip that is substantially adjacent to the restricting protrusion, and is configured to allow the fixing member to be more easily passed through the first and second positioning holes wherein after the fixing member movably passes through the first positioning hole and the second positioning hole, under a restoring force of the flexible arm, the restricting protrusion abuts against the fixing block, in response to pressure applied to the arc-shaped pressing portion, provides a bending force to bend the flexible arm and the restricting protrusion to move inward to enable the fixing member to be completely removed from the first positioning hole and the second positioning hole.

2. The positionable lift stand of claim 1 , wherein the positionable lift stand is adapted to a display, and wherein the display is connected to the sliding member with the weight of the display being substantially the same as the restoring force of the elastic member.

3. The positionable lift stand of claim 2 , wherein the display comprises a mounting member for connecting to the sliding member.

4. The positionable lift stand of claim 1 , wherein the support structure comprises at least one guide rail, and wherein the sliding member includes at least one slide rail slidably engaged with the guide rail.

5. The positionable lift stand of claim 4 , wherein the guide rail has a limiting block formed on one end thereof and the slide rail has a barb formed on one end thereof, and when the slide rail is slid to the end of the guide rail, the barb is abutted against the limiting block.

6. The positionable lift stand of claim 1 , wherein the sliding member has an arched recess for abutting the elastic member.

7. The positionable lift stand of claim 6 , wherein the elastic member is a flat spiral spring.

8. The positionable lift stand of claim 1 , further comprising a shield disposed on the support structure, wherein the shield has a third positioning hole for passing through by the fixing member.

9. The positionable lift stand of claim 1 , further comprising a cover enclosing and moving with the sliding member.
