DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a clamping device for detachably connecting two profiled parts in accordance with the preamble of Patent Claim 1.
A clamping device disclosed in CH-A-576 591 serves for connecting the profiled parts of removable frames and/or walls. For this purpose, there is provided a longitudinally displaceable bolt which is guided in an insert core and which, at its head end, is of T-shaped design in order to engage behind a slot in another profiled part. The bolt is displaced longitudinally by a screw having a conical tip being pressed eccentrically against a conical recess, serving as a tightening surface, in the bolt.
Another clamping device of this type is disclosed in EP-B1-0 506 607. In this clamping device the bolt has supporting means for the pivotable mounting of a plurality of retaining parts, each retaining part and the inner walls of the insert core comprising a system of sliding surfaces in order to enable the retaining parts to pivot when there is an axial movement of the bolt. The free end regions of the retaining parts are in each case designed in the form of a hook in order to exert the desired clamping pressure when pivoting.
A further clamping device of this type is disclosed in EP-B1-0 123 683. In this clamping device the stay bolt is secured by being extended by means of a rod with a widened end part, and by the insert core being provided with spreading fingers and having inwardly protruding pumps in order to engage behind the widened end part. A snap fastening of this type can also be implemented by means of an integrally moulded-on sleeve having at least one longitudinal slot in which is guided a pin which is arranged diagonally in the rod.
Furthermore, French Patent 2,152,941 describes a device having retaining elements which are mounted rotatably about an axis arranged in a positionally fixed manner in the housing. This device does not have a bolt and a screw engaging in the bolt via sliding surfaces; rather, the retaining elements are pivoted by an eccentric, the height of which corresponds to the width of the housing. The housing does not have any sliding surfaces causing the retaining elements to pivot when they are moved axially; rather, the sliding surfaces are located in the eccentric and in the lower region of the retaining elements or of a pressure-transmitting part which displaces the retaining elements.
The object of the present invention is to provide an improved clamping device of the type mentioned at the beginning.
This object is achieved according to the invention by a clamping device having the features given in the characterizing part of Patent Claim 1.
Further advantageous refinements of the invention are given in the dependent claims.
The invention is explained in more detail below with reference to a drawing by way of example, in which:
FIG. 1 shows a sectional illustration through the eccentric axis of a clamping device according to the invention with the insert core in the closed state,
FIG. 2 shows a plan view of part of this clamping device and its slide,
FIG. 3 shows a sectional illustration of the eccentric portion of this clamping device in a plane transversely with respect to the longitudinal axis,
FIGS. 4 and 5 show illustrations of a variant of a slide of this type,
FIGS. 6 to 8 show illustrations of an insert core,
FIGS. 9 and 10 show illustrations of a resilient locking plate from the side and from above,
FIG. 11 shows a plan view of a further embodiment of the clamping device according to the invention with special latches,
FIG. 12 shows a sectional illustration through the eccentric axis of this embodiment,
FIG. 13 shows a plan view of the lower housing part of this embodiment,
FIG. 14 shows a sectional illustration according to the line A--A in FIG. 13,
FIG. 15 shows a plan view of the upper housing part of this embodiment,
FIG. 16 shows a sectional illustration according to the line B--B in FIG. 15,
FIG. 17 shows a sectional illustration of an eccentric for this embodiment,
FIG. 18 shows a plan view of an eccentric of this typ
