Abstract

An exemplary flat panel display (200) includes a display body (21) and a height adjusting member (23). The height adjusting member includes a supporting member (25) and a base (26). The supporting member includes a slider (30) and a sidewall (272). The slider is attached to the display body, and the slider abuts against but is slidable up and down along the sidewall. The slider is configured to be adjustable to vary an amount of friction between the slider and the sidewall such that a height of the display body is adjustable by applying external force to the display body and moving the display body to a new height.

Claims

1. A flat panel display, comprising:

a display body; and

a height adjusting member comprising a supporting member and a base;

wherein the supporting member comprises a slider and a sidewall, the slider is attached to the display body, and the slider abuts against but is slidable up and down along the sidewall, the slider is configured to be adjustable to vary an amount of friction between the slider and the sidewall such that a height of the display body is adjustable by applying external force to the display body and moving the display body to a new height.

2. The flat panel display as claimed in claim 1, wherein the amount of friction increases when the distance between the slider and the base increases, and the amount of friction decreases when the distance between the slider and the base decreases.

3. The flat panel display as claimed in claim 1, wherein a surface of the sidewall against which the slider abuts is rough.

4. The flat panel display as claimed in claim 3, wherein the surface of the sidewall against which the slider abuts comprises an antiskid tape.

5. The flat panel display as claimed in claim 1, wherein the supporting member has a generally tapered wedge configuration.

6. The flat panel display as claimed in claim 1, wherein the supporting member gradually tapers from bottom to top.

7. The flat panel display as claimed in claim 1, wherein the supporting member further comprises a first elastic member, and the first elastic member exerts upward elastic force on the slider.

8. The flat panel display as claimed in claim 7, wherein the first elastic member is a spring disposed between the base and the slider.

9. The flat panel display as claimed in claim 8, wherein the supporting member further comprises a supporting post disposed therein, the supporting post extends through the slider such that the slider is slidable up and down along the supporting post, and the first elastic member is located around the supporting post.

10. The flat panel display as claimed in claim 7, wherein the slider comprises an attaching portion and a sliding block, the attaching portion is attached to the display body, and the sliding block abuts against but is slidable up and down along the sidewall.

11. The flat panel display as claimed in claim 10, wherein the attaching portion is hollow, and the sliding block is received in the attaching portion.

12. The flat panel display as claimed in claim 10, wherein the sliding block comprises a second elastic member, and the second elastic member exerts horizontal elastic force such that the sliding block abuts against but is slidable up and down along the sidewall.

13. The flat panel display as claimed in claim 12, wherein the second elastic member is a spring.

14. The flat panel display as claimed in claim 12, wherein the sliding block further comprises a first portion and a second portion, and the second elastic member is in a compressed state between the first portion and the second portion.

15. The flat panel display as claimed in claim 14, wherein the first portion comprises a protrusion, the second portion comprises a groove, the second elastic member is located around the protrusion, and the second elastic member and the protrusion are at least partly received in the groove and movable in the groove.

16. The flat panel display as claimed in claim 15, wherein the slider further comprises an adjusting piece movable relative to the first portion, and when the adjusting piece is manipulated by a user, an amount of deformation of the second elastic member is adjusted to a desired amount.

17. The flat panel display as claimed in claim 16, wherein the attaching portion includes a receiving hole, the adjusting piece is inserted through the receiving hole, with a free end thereof abutting against the first portion.

18. The flat panel display as claimed in claim 1, wherein the supporting member further comprises a top wall, and the sidewall further comprises a blocking piece extending therefrom, the top wall and the blocking piece defines a channel for the slider to slide along the sidewall.

19. A flat panel display, comprising:

a display body; and

a height adjusting member having a supporting member and a base;

wherein the supporting member comprises a slider and a sidewall, the display body is slidably engaged to the base via the slider, the slider and the sidewall cooperatively provide variable friction for the slider to realize an adjustable height of the display body, and the amount of friction is determined by at least a distance between the slider and the base.

20. The flat panel display as claimed in claim 19, further comprising an elastic member exerting upward force on the slider, wherein gravitational force acting on the display body, the upward force, and the friction cooperate to hold the display body at a desired height while enabling the height to be adjustable by the application of external force on the display body.
