Abstract
The connector is intended for beams having longitudinal, undercut grooves, the coupling elements engaging in these grooves. It consists of coupling elements that can swing freely in the transverse plane of the groove; these coupling elements have hook heads, the head thickness of which, taken in total, is less than the width of the entry of the groove. They are pressed into contact with the two opposing walls of the constricted entry of the groove by an adjuster; the adjuster is installed in one coupling element in such a manner as to be adjustable by external action. The pressure exerted by the adjuster can be transmitted to the other coupling element through a spring. Equalized contact pressure on the walls of the groove is achieved by the coupling elements.
Claims5
A connector for beams with a longitudinal undercut groove adapted to receive the connector comprising a first coupling element and a second coupling element adapted to swing transverse to the plane of the groove, each said connector element including a hook head of a thickness slightly less than half the width of the opening of said groove and an adjuster which includes a spring held in said first and second coupling elements, which adjuster resiliently biases said coupling element away from said second coupling element, said spring being capable of biasing apart the hook head of the first and second coupling elements by a distance that is, at least, greater than the width of the groove entry, said adjuster including a guide sleeve arranged between the spring and said first coupling element, the aforesaid guide sleeve being movable and protruding beyond the outer side of the first coupling element through a first bore, said first bore adapted to align with a third bore through the beam when in the connected position, such that a projecting portion of said guide sleeve can lock into said third bore.
