The shell 11 includes two first protruding ribs 111, two second protruding ribs 112, two third protruding ribs 113, and two fourth protruding ribs 114, which are protruded toward the accommodating space 12, and includes two first surfaces 1111, two second surfaces 1112, two third surfaces 1113, and two fourth surfaces 1114, which are corresponding to the accommodating space 12. The first surfaces 1111, the second surfaces 1112, and the third surfaces 1113 are sequentially connected, and the second surfaces 1112 are formed between the first protruding ribs 111 and the second protruding ribs 112, and the first surfaces 1111 are formed on the first protruding ribs 111 and adjacent to the second surfaces 1112, the third surfaces 1113 are formed on the second protruding ribs 112 and adjacent to the second surfaces 1112. Practically, the shell 11 is prepared through aluminum extrusion and bending. The preparation steps include forming an elongated plate with four protruding ribs through aluminum extrusion. The elongated plate is then bent after removing a portion of the protruding ribs.

The first plate 13, including an elongated opening 131, is disposed at the first opening 15 and engaged to the third protruding ribs 113, the second plate 14 is disposed at the second opening 16 and engaged to the fourth protruding ribs 114, in other words, the first plate 13 and the second plate 14 are located on the front side and the rear side of the shell 11 respectively.

Please refer to FIG. 4, the slider 2 includes a main part 21, an elongated arm 22, and six self-lubricating blocks 23, wherein the main part 21 is slidably disposed in the accommodating space 12, and the self-lubricating blocks 23 of the slider 2 are disposed between the main part 21 and the shell 11 respectively, and each of the self-lubricating blocks 23 contacts with the first surface 1111, the second surface 1112, and the third surface 1113 respectively; the elongated arm 22 is connected to the main part 21, protruding out of the support 1 through the first opening 15 and the elongated opening 131 of the first plate 13, and connected to the connecting base 6.

Further, the pressing block 3 is fastened to the main part 21 of the slider 2 through a bolt 7. A spring 8 (refer to FIG. 5) is further disposed between the pressing block 3 and the main part 21, the bolt 7 passes through the spring 8 and is fixed to the main part 21 so that the connection between the pressing block 3 and the main part 21 may be ensured by the spring 8.

More specifically, please refer to the cross-section view of the support 1 illustrated in FIG. 3. The second protruding ribs 112 of the shell 1 incline toward the first opening 15; therefore, a dovetail zone 121 is formed with respect to the fourth surfaces 1114. Please refer to the explosive view of the slider 2 and the pressing block 3 illustrated in FIG. 4, wherein the main part 21 includes symmetrical two front surfaces 211, two side surfaces 212, two inclined surfaces 213, and two concave surfaces 214. The front surfaces 211 face the first opening 15 and are adjacent to the elongated arm 22; the side surfaces 212 are adjacent to the front surfaces 211 and substantially perpendicular to the front surfaces 211; the inclined surfaces 213 are adjacent to the side surfaces 212, and an acute angle is formed between the inclined surface 213 and the side surface 212; the concave surfaces 214 are adjacent to the inclined surfaces 213 and corresponds to the second protruding ribs 112 of the shell 11.

Also, the number of the self-lubricating blocks 23 is six, which are respectively disposed on the front surfaces 211, the side surfaces 212, and the inclined surfaces 213 of the main part 21. Specifically, in the slider 2, each of the front surfaces 211, the side surfaces 212, and the inclined surfaces 213 of the main part 21 further include two notches 2111, 2121, and 2131 respectively (as illustrated in FIG. 2 and FIG. 5). The self-lubricating blocks 23 disposed correspondingly to the front surfaces 211, the side surfaces 212, and the inclined surfaces 213 respectively include a bump 231 serving as an engaging structure. The notches 2111, 2121, 2131 engage to the bumps 231 which are correspondingly disposed. Therefore, those self-lubricating blocks 23 may be fixed firmly on the front surfaces 211, the side surfaces 212, and the inclined surfaces 213 of the main part 21. In the present embodiment, the self-lubricating blocks 23 are made of ultra-high molecular weight polyethylene (Lubmer L5000; Mitsui Chemicals, Inc.) which has a lower friction coefficient; thus the slider 2 may slide smoothly along the shell 11.

In another embodiment, however, the self-lubricating blocks 23 may be prepared through injection molding, and the plastic materials may be embedded into the notches 2111, 2121, 2131 of the front surfaces 211, the side surfaces 212, and the inclined surfaces 213 of the main part 21 to form the self-lubricating blocks 23 which are firmly engaged to the main part 21. Alternatively, in yet another embodiment, a plurality of bumps may be formed on the front surfaces 211, the side surfaces 212, and the inclined surfaces 213 of the main part 21, and the plastic material may cover the main part 21 of the slider 2 and surround those bumps through injection molding in order to form the self-lubricating blocks 23 engaging with the main part 21.

In addition, please refer to the explosive view illustrated in FIG. 5, the slider 2 further comprises a convex portion 24 formed at the concave portion 215 at the bottom of the main part 21, and the center of the convex portion 24 has a first screw hole 241. The spring 8 is sleeved to the convex portion 24. The pressing block 3 includes two side surfaces 31 and a through hole 32 and has a dovetailed cross-section. The bolt 7 passes the through hole 32 and the first screw hole 241 sequentially so that the pressing block 3 is bolted on the main part 21. Accordingly, the side surfaces 31 face toward and tightly press each of the fourth surfaces 1114 of the shell 11 respectively.

Please refer to FIG. 6 illustrating the cross-sectional view of the slider 2 and the pressing block 3 disposed in the support 1. The contour of the main part 21 conforms to the cross-section of the shell 11, and the self-lubricating blocks 23 disposed on the front surfaces 211, the side surfaces 212, and the inclined surfaces 213 of the main part 21 contact with the first surfaces 1111, the second surfaces 1112, and the third surfaces 1113 of the shell 11. The self-lubricating blocks 23 rub the first surfaces 1111, the second surfaces 1112, and the third surfaces 1113 of the shell 11 when the slider 2 slides up and down along the support 1. In other words, the similar effect of the slide and the slide rail may be achieved.

Also, when the pressing block 3 is fixed to the main part 21 of the slider 2, the side surfaces 31 of the pressing block 3 are tightly contacted to the fourth surfaces 1114 of the shell 11 and pull the slider 2 against shell 11 in a direction facing the second opening 16. Particularly, the contact between the self-lubricating blocks 23 and an inner surface of the shell 11 may be ensured by the tight contact between the third surfaces 1113 of the shell 11 and the corresponding self-lubricating blocks 23. In other words, due to the fine adjustment, the effect of the tolerance problems may be avoided. Also, the spring 8 disposed between the pressing blocks 3 and the main part 21 may serve as a buffer to keep the pressing blocks 3 and the main part 21 from sticking.

Furthermore, please refer to FIG. 2 again, each of the constant force springs 4 is applied as the elastic element of the present invention which has a winding portion 41 and a free end 42 corresponding to the winding portion 41. The winding portions 41 of the constant force springs 4 are accommodated on a supporting base 17 of the support 1, and the free ends 42 are fastened to the main part 21 of the slider 2 through a fastening member 18. As the slider 2 slides up and down, the distribution between the winding portion 41 and the free end 42 changes in order to provide a constant force so that the slider 2 will not be stuck on the support 1. In addition, the connecting base 6 is pivoted to the elongated arm 22 of the slider 2; accordingly, the connecting base 6 may rotate an angle with respect to the elongated arm 22 for adjusting the view angle of the display device (not shown in figures) mounted on the connecting base 6.

In another embodiment, the location of the constant force springs 4 in the support 1 is not particularly limited as long as the free ends 42 of the constant force springs 4 are fastened to the main part 21 of the slider 2 and may move with the slider 2. For example, the winding portions 41 of the constant force springs 4 may be vertically arranged or be disposed at any position of the support 1 and be supported by the supporting bases 17. Also, the number of the constant force springs 4 may be altered according to different situations.

Please refer to FIG. 7, which illustrates the cross-sectional view of the supporting device 1000 when the slider 2 is at a highest position. When the slider 2 is at the highest position, an elastic force provided by the constant force springs 4 is balanced with the weight of the slider 2, the connecting base 6, and the display device (not shown in figure) mounted on the connecting base 6 and the friction formed between the self-lubricating blocks 23 and the shell 11; therefore, the slider 2 may stop at the highest position.

When a force is applied downwardly to the slider 2, the slider 2, the winding portions 42 of the constant force springs 4, the connecting base 6, and the display device may move downward simultaneously. The slider 2 moves downwardly along the shell 11 with the self-lubricating blocks 23 disposed on the surface of the main part 21. At the meantime, the length of the free ends 42 of the constant force springs 4 increases, that is, the length distributed in the free ends 42 increases and the length distributed in the winding portions 41 decreases. The elastic force still constantly provided by the constant force springs 4. Please refer to FIG. 8, when the force is removed, the elastic force provided by the constant force springs 4, the weight of the slider 2, the connecting base 6, and the display device (not shown in figures) mounted on the connecting base 6, and the friction formed between the self-lubricating blocks 23 and the shell 11 are balanced. Therefore, the display device may stop at any position with respect to the support 1.

On the contrary, when a force is applied upwardly to the slider 2, the slider 2, the self-lubricating blocks 23, the free ends 42 of the constant force springs 4, the connecting base 6, and the display device (not shown in figures) may move upward simultaneously. At the meantime, the slider 2 moves upwardly along the shell 11 with the self-lubricating blocks 23 disposed on the surface of the main part 21, and the free ends 42 of the constant force springs 4 rewind to the winding portions 41 and constantly provide the elastic force. When the force is removed, the elastic force provided by the constant force springs 4 may sustain the weight of the slider 2, the connecting base 6, and the display device mounted on the connecting base 6 so that the display device may stop at any height with respect to the support 1.

Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
