DETAILED DESCRIPTION
Referring to FIG. 1, according to an exemplary embodiment, a height-adjustable display device 10 includes a base 20 defining a chamber 22, a supporting member 40 and a latching member 60. A display 80 is rotatably fixed to the top of the supporting member 40. The supporting member 40 is received and vertically movable in the chamber 22, thereby adjusting the height of the display 80. The supporting member 40 defines a number of vertically oriented grooves grooves 42 therein. The grooves 42, as a whole, are arrange along a vertical direction. The latching member 60 is pivotedly mounted to the base 20 can be engagingly received in one of the grooves 42, thus retaining the supporting member 40 in a desired vertical position.
Referring to FIGS. 2 and 3, the base 20 includes a pedestal 24, a first sleeve 26 protruding from the pedestal 24 and a second sleeve 28. The first sleeve 26 defines a space 30. The second sleeve 28 is received in the space 30. The chamber 22 is formed in the second sleeve 28. The first sleeve 26 defines a positioning hole 32 in a sidewall. The second sleeve 28 defines a through hole 34 in a sidewall. The positioning hole 32 and the through hole 34 are aligned with each other groove 42. A pin 36 extends through the latching member 60 and includes two ends fixed to opposite edges of the positioning hole 32. The second sleeve 28 further defines a blind hole 38 below the through hole 34 and a sliding groove 21 along the height. The second sleeve 28 includes two ears 23 extending outward from opposite sides at an open end. The ears 23 are fixed to the edges at the top, open end of the first sleeve 26. In the exemplary embodiment, the second sleeve 28 is box-shaped. The sliding groove 21 is defined in a sidewall opposite the sidewall where the through hole 34 is defined.
The supporting member 40 includes a main body 44, two horizontally oriented rods 48 coupled to the main body 44 and two torsional spring sheets 50 respectively coiled around the rods 48. The display 80 is rotatably fixed to the top of the body 44. The grooves 42 are defined in a sidewall of the body 44. The body 44 is substantially cubed. The body 44 includes two plates 46 fixed to opposite sides and a protrusion 47 protruding from the one of the plates 46. Each plate 46 defines two through holes (not labeled) at opposite ends. Opposite ends of each rod 48 are inserted in two through holes of the two plates 46. The protrusion 47 is slidably received in the sliding groove 21 and serves as a stop to prevent the supporting member 40 from moving out of the chamber 22. In an alternative embodiment, the protrusion 47 may be formed on the body 44. Each torsional spring sheet 50 includes one end fixed to the ear 23 and another end fixed to the rod 48. The torsional spring sheets 50 are configured to urge the supporting member 40 toward a vertically upward direction.
The latching member 60 is rotatably received in the positioning hole 32 via the pin 36 The latching member 60 includes a hook 66 at one end. The hook 66 extends through the through hole 34 and can be received in one of the grooves 42, thus retaining the supporting member 40 in a desired vertical position. The height-adjustable display device 10 further includes a spring member 64. One end of the spring member 64 is received in the blind hole 38, and the other end of the spring member 64 abuts against other end of the latching member 60 away the hook 66. The spring member 64 applies a push force to the end of the latching member 60, which causes the hook 66 to be tightly received in the groove 42.
Referring to FIGS. 3 and 4, when attempting to adjust the height of the display 80, a user can press the latching member 60. The clasping member 62 then rotate and the hook 66 moves out of one groove 42. The supporting member 40 then frees from the limitation of the hook 66. The user can then pull the display 80 upward or push the display 80 downward to a desired vertical position and release the latching member 60. The latching member 60 is then urged to rotate back under the elastic force of the spring member 64 until the hook 66 is received in one of the grooves 42, thereby retaining the display 80 in the desired vertical position. During the pulling of the display 80 upward, the torsional spring sheets 50 rebounds and provides a pushing force pushing the display 80 upward.
In the exemplary embodiment, the grooves 42 are saw-toothed. The distal end of the hook 66 is formed with a wedge-shaped surface 65 matching an inclined surface of the groove 42 receiving the hook 66. When adjusting the height of the display 80 downward, the user can directly push the display 80 downward. The wedge-shaped surface 65 is pushed by the inclined surface of the groove 42 and the hook 66 is urged to move out of the groove 42. When the user stops pushing the display 80, the hook 66 is received in one of the grooves 42 again.
It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the present disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
