Abstract
A clip system for clamping a panel element against a rebate comprises a bolt which is movable between a first position for clamping the panel element against a rebate and a second position for releasing the panel element, and an operating mechanism for moving the bolt. According to the invention, depending on the position of the bolt, there is a variable transmission ratio between the operating mechanism and the bolt, with a reduction which increases as the bolt in a path near the first position nears said first position. Operation of the bolt consequently requires little force and can be carried out with a short movement. The clip system can be achieved by a simple construction requiring little maintenance.
Claims15
A panel for closing an opening, with a panel element and a clip system for clamping said panel element against a rebate of the opening, comprising at least two bolts each movable between a first position for clamping the panel element against a rebate and a second position for releasing the panel element and common operating mechanism for moving said bolt, said operating mechanism comprising
- at least two levers each pivotable about an axis, connected to a corresponding one of the bolts and provided with a guide strip in an essentially lengthwise direction,
- at least two pawls each for operating a corresponding one of said levers, and
- a pawl support onto which said pawls are fitted and movable in curved translatory motion such that the pawls fitted to the pawl support are each movable along a correspondingly curved tract of which a part corresponding to positions of the bolts near the first position is curved away from the pivoting axis of the respective lever and has a course with a radial component relative the pivoting axis of the respective lever such that the distance between corresponding ones of the pawls and the axes increases as the bolts approach said first positions.
