Liquid crystal display and backframe for liquid crystal display
View Patent ↗The present invention discloses a liquid crystal display and a backframe for a liquid crystal display. The backframe is configured by interlinked linkages such that the backframe can be locked in a fully extended position in use, or be collapsible when not in use in a way that the overall dimension of the collapsible backframe is smaller than the fully extended backframe. The backframe can be switched from a fully extended position under normal use, or a collapsible position under a transportation or storage. The collapsible position occupies less volumetric weight as compared to the fully extended position so as to reduce the volumetric weight when the backframe is in transportation and storage. As a result, the performance of the transportation and storage can be therefore increased, while the cost is reduced.
1. A backframe for a liquid crystal display, comprising
a pair of primary struts arranged in parallel to each other;
a pair of secondary bars arranged in parallel to each other and pivotally interlinked to the pair of primary struts by means of pinshafts at ends thereof in a way that the backframe configured by the interlinked primary struts and the secondary bars are collapsible when not in use or fully extended in use such that a compact dimension of the backframe can be achieved when not in use;
wherein a stopper is provided at an interlinked junction of the primary struts and the secondary bars so as to lock the fully extended position in use; and
wherein further comprises a first assisting beam arranged in parallel to the secondary bars, and the first assisting beam is pivotally interlinked to the primary struts via pinshafts.
2. A backframe for a liquid crystal display, characterized in that
the backframe is configured by interlinked linkages such that the backframe can be locked in a fully extended position in use, or be collapsible when not in use in a way that the overall dimension of the collapsible backframe is smaller than the fully extended backframe;
wherein the interlinked linkage is configured by a pair of primary struts, and a pair of secondary bars pivotally interlinked with pinshafts at ends of the struts and the bars; and
wherein a stopper is provided at an interlinked junction of the primary struts and the secondary bars so as to lock the fully extended position of the primary struts and the secondary bars in use.
3. The backframe as recited in claim 2 , wherein comprises a first assisting beam arranged in parallel to the secondary bars, and the first assisting beam is pivotally interlinked to the primary struts via pinshafts.
4. The backframe as recited in claim 3 , wherein there is two first assisting beams, and the backframe further includes a secondary assisting beam which is arranged in parallel to the primary struts, and is pivotally interlinked to those two first assisting beams.
5. The backframe as recited in claim 2 , wherein there are four assisting beams, and the primary struts and the secondary bars are pivotally interlinked to the corresponding assisting beams by corner brackets and pinshafts.
6. The liquid crystal display as recited in claim 2 , wherein the first primary struts arranged in parallel under normal use, and secondary bars arranged in parallel under normal use, and at least a pair of assisting beams arranged diagonally and being pivotally interlinked with each other by means of a central bracket, ends of the pair of primary struts and the pair of secondary bars and assisting beams are pivotally interlinked by means of corner brackets and the pinshafts.
7. A liquid crystal display configured with a liquid crystal display panel and a backframe, the backframe is configured by interlinked linkages such that the backframe can be locked in a fully extended position in use, or be collapsible when not in use in a way that the overall dimension of the collapsible backframe is smaller than the fully extended backframe;
wherein the interlinked linkage is configured by a pair of primary struts, and a pair of secondary bars pivotally interlinked with corner brackets and pinshafts at ends of the struts and the bars; and
wherein a stopper is provided at an interlinked junction of the primary struts and the secondary bars so as to lock the fully extended position of the primary struts and the secondary bars in use.
8. The liquid crystal display as recited in claim 7 , wherein further includes four assisting beams arranged diagonally, and the primary struts and the secondary bars are pivotally interlinked to the corresponding assisting beams by the corner brackets and pinshafts.
9. The liquid crystal display as recited in claim 8 , wherein the four assisting beams are interconnected by a central bracket.
10. The liquid crystal display as recited in claim 7 , wherein the primary struts arranged in parallel under normal use, and the secondary bars arranged in parallel under normal use, and at least a pair of assisting beams arranged diagonally and being pivotally interlinked with each other by means of a central bracket, ends of the pair of primary struts and the pair of secondary bars and the assisting beams are pivotally interlinked by means of the corner brackets and pinshafts.
