BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a profiled member for clamping plate-like elements, especially plates of glass, for display cases, shop counters, exposition furniture, or the like.
DESCRIPTION OF THE PRIOR ART
In contrast to other plate fastening means having clamping strips (German Pat. No. 875,435 Braun dated May 4, 1953), profiled members have the advantage of a more completely effective and easier securing of the plate-like elements. Such profiled members are known as gripping strips for the front plates of shop counters, and are provided with a groove or slot for accommodating the edge of a plate-like element. They have an enlarged slot portion that widens in the direction toward the base of the slot, and serve for mounting a clamping strip having a wedge-shaped cross-section, the wedge point of which faces the introduction opening of the slot. Disposed in the enlarged slot portion, in the region of the base of the slot, is a threaded bore in which is adjustably provided a pressure screw which contacts an abutment surface of the clamping strip that delimits the wedge cross-section. The pressure application direction of the pressure screw that acts upon the clamping strip here extends parallel to the plane of the plate-like element, so that the force exerted by the pressure screw is deflected, with only a small force component being used for clamping the introduced plate-like element. Since during the clamping process the clamping strip moves in the direction toward the opening of the slot, there exists the danger that the plate-like element will be taken along, and will therefore be increasingly pressed out of the slot. There is no assurance that the plate-like element will always be held securely in the slot of the profiled member to the completely desired depth.
An object of the present invention is to provide an economical profiled member of the aforementioned general type whereby the plate-like element can be reliably and particularly securely clamped in the slot via a simple and convenient operation.
SUMMARY OF THE INVENTION
This object is realized by the profiled member of the present invention, which comprises: at least one slot means that extends in the longitudinal direction of the profiled member, with each slot means being defined by a first and a second stationary planar wall, with these walls being disposed at an angle to one another, and with one of these walls being in the form of a guide surface, with said slot means being further defined by a third wall that proceeds from the second wall and, remote from the latter, has a free edge that defines an introduction opening, for a plate-like element, remote from a base portion of the slot means that interconnects the first and second walls, with the third wall and the second wall defining a triangular-shaped, enlarged portion of the slot means, with the third wall being provided with threaded through-holes for accommodating pressure-applying screws; also provided is a profiled clamping strip that can be accommodated in the enlarged slot portion and can be displaced by the pressure-applying screws, with each clamping strip having a fundamentally wedge-like cross-sectional shape which, when the clamping strip is installed in an enlarged slot portion, includes a wedge point region that faces the base portion of the slot, a first wedge surface adjacent to the wedge point that is displaceably supported on the guide surface, a second wedge surface adjacent to the wedge point that extends parallel to the first wall and defines, within the slot means, a parallel-walled slot of changeable width for accommodating and holding in place an edge portion of a plate-like element, with said clamping strips also including an abutment surface that interconnects the first and second wedge surfaces and is acted upon by the pressure-applying screws, with the pressure-application direction of each screw extending parallel to the guide surface; said clamping strip is furthermore provided with integral parts that project from the
