Embodiment Construction

[0034] figure 1 An embodiment of a portion 10 of an extendable load-bearing structure 1 is shown. The extendable load-bearing structure 1 may comprise one such portion 10, or two or more such portions 10 connected in series. The figure shows how the extendable load-carrying structure 1 consists of a main structure 2 comprising pairs of four inner Vs 25a, 25b, 26a, 26b facing oppositely. These V 25 a , 25 b , 26 a , 26 b are each formed by a drive arm 21 each formed by two drive arm elements 22 connected to each other by a joint 23 . Furthermore, the figure shows how the supporting structure 3 of the carrying structure 1 comprises pairs of four oppositely facing outer V 35a, 35b, 36a, 36b, each V 35a, 35b, 36a, 36b being formed by a supporting arm 31, Each support arm 31 consists of two support arm elements 32 connected to each other by a joint 33 . The support arm 31 is shorter than the drive arm 21 so that the support arm 31 will reach the extended position before the driv...

Abstract

An extendable, load-bearing structure (1) comprising a main structure (2) and a driving element (6a, 6b, 6c), wherein an extent of the extendable, load-bearing structure (1) is arranged to be changeable in both directions between a first position, in which the extendable, load- bearing structure (1) has a smallest extent, and a second position, in which the extendable, load-bearing structure (1) has a largest extent, the main structure (2) including at least one driving arm (21), and the driving element (6a, 6b, 6c) being placed in connection with the at least one driving arm (21) to drive theextendable, load-bearing structure (1) between said positions, the extendable, load-bearing structure (1) including a lock mechanism (4), and the extendable, load-bearing structure (1) including a supporting structure (3), the supporting structure (3) including at least one supporting arm (31), the at least one supporting arm (31) of the supporting structure (3) being shorter than the at least one driving arm (21) of the main structure (2), the supporting arm (31) including at least two supporting-arm elements (32) which are connected to each other by joints (33), the supporting-arm elements(32) of the supporting arm (31) being substantially in line when the extendable, load-bearing structure (1) is in its second position, and the lock mechanism (4) being arranged to releasably lock thesupporting-arm elements (32) of the supporting arm (31) in position when these are in line.

Description

technical field [0001] The invention relates to an extendable load-bearing structure comprising a main structure and drive elements. The extent of the extendable load-bearing structure is configured to be variable in two directions between a first position in which the extendable load-bearing structure has a minimum extent and a second position in which the extendable load-bearing structure is in a second position has the largest range. The primary structure includes at least one drive arm. A drive element is positioned in connection with at least one drive arm to drive the extendable load-bearing structure between said positions. The invention also includes a method for erecting an extendable load-bearing structure. Background technique [0002] Extendable structures are previously known, for example for lifts and so-called "scissor lift tables". [0003] Elevators typically have a drive arm that can drive the platform between a first position and a second position. Th...
