Each track 12 has a lateral surface 121 and two restricting surfaces 122 concavely formed thereon. In other words, the lateral surfaces 121 of the tracks 12 are arranged on opposing sides of the frame 1. Moreover, the restricting surfaces 122 of opposite tracks 12 are respectively formed along a first direction and a second direction (i.e., the directions pointed by the right arrow and the left arrow in
Specifically, the longitudinal direction C, the first direction, and the second direction in this embodiment are parallel to each other. Thus, the relationships related to the first direction and the second direction in the following description are described or defined by the longitudinal direction C.
The movable units 20 are disposed on respective tracks 12. The two tracks 12 are identical to each other, and the movable units 20 are identical to each other as well. In addition, the tracks 12 and the movable units 20 are arranged symmetrically with respect to the plate 11. Thus the following description is provided for one track 12 and the corresponding movable unit 20.
As shown in
More specifically, for the cross-section perpendicular to the longitudinal direction C of each restricting surface 122, the largest separation distance between any two points of opposing sides of the second restricting segment 1222 is greater than the largest separation distance between the first restricting segments 1221. In other words, each restricting surface 122 defines a restricting trough 1223. As shown in
The track 12 has a plurality of positioning holes 1211 concavely formed on the lateral surface 121, and the positioning holes 1211 are arranged between the two restricting troughs 1223 and vertically spaced along the longitudinal direction C.
As shown in
As shown in
The cross-section perpendicularly to the longitudinal direction C of each sliding block 212 is T-shaped (as shown in
The fixing plate 213 is extended from the bottom edge adjacent to the lateral surface 2112 of the pivoting portion 211. The fixing plate 213 has a penetrating hole 2131 arranged below the two sliding blocks 212.
As shown in
Based on the above, when the two movable units 20 are set on the frame 1, the sliding blocks 212 of the two sliding components 21 are respectively disposed in the restricting troughs 1223 of the two tracks 12, and the contacting surfaces 2121 respectively contacting the restricting surfaces 122. That is to say, the first contacting segments 2122 respectively contact the first restricting segments 1221, and the second contacting segments 2123 respectively contact the second restricting segments 1222. Thus, the contacting surfaces 2121 of the two sliding components 21 respectively contact the restricting surfaces 122 of the two tracks 12 for enabling the two sliding components 21 to move respectively along the first direction and the second direction.
Subsequently, when the two movable units 20 are respectively adjusted at two positions and the penetrating hole 2131 of each sliding component 21 is aligned to one of the positioning holes 1211 of each tracks 12, the fixing components 23 are respectively passed through the penetrating holes 2131 and the corresponding positioning holes 1211 such that the two movable units 20 are respectively fixed at the two positions. Besides, the fixing components 23 can be respectively abutted to the lateral surfaces 121 of the tracks 12 for pressing the sliding components 21 toward the corresponding tracks 12 to achieve the fixing effect between the sliding components 21 and the corresponding tracks 12. Moreover, the two movable units 20 can be respectively position on the frame 1 at different heights (as shown in
Besides, the supporting stand 100 can be used for supporting three screens 300. As shown in
Moreover, the movable module 2 further has an auxiliary movable unit 20′ corresponding to the auxiliary track 12′. In
Specifically, the structure of the auxiliary movable unit 20′ is approximately identical to the movable unit 20. The auxiliary sliding component 21′ has a contacting surface 2121′ corresponding to the restricting surface 122′.
Thus, the auxiliary movable unit 20′ is movable along the third direction by the contacting surface 2121′ of the auxiliary sliding component 21′ contacting the restricting surface 122′ of the auxiliary track 12′. The longitudinal direction C, the first direction, the second direction, and the third direction in this embodiment are parallel to each other, but not limited thereto.
Based on the above, the supporting stand for multiple screens of the instant disclosure uses the contacting surface of each sliding block matching to the restricting surface of each track for enabling the contacting surfaces of the sliding blocks to be moved respectively along the restricting surfaces of the tracks. Thus, the movable units of the movable module can be respectively adjusted to the desired positions for achieving different user's demands.
Furthermore, the movable units of the movable module can be respectively fixed at desired positions by co-operating the fixing components with the positioning holes of the tracks, so that the supporting stand can be applied to different operating situations.
