Abstract
ABSTRACT
An assembly for clamping a glass panel comprises a metal section having a tapered groove along its length, a deformable clamping section fitting into the tapered groove, an elastic member installed between the clamping section and outer end of the glass panel, a fastener for holding the clamping section tight in the tapered groove whereby the outer end of the glass panel to be clamped may be inserted in said clamping section and clamped.

Description
This invention relates to glass fasteners and more particularly concerns a fastening for glass in metal sections, in other words, a fastening method for mounting glass panels in window frames, doors, etc.
In a particular embodiment the invention concerns a fastening method for panels of safety glass in swinging doors, where, as is known, such glass doors consist primarily of two plinths and the glass panel held between them.
It is known that the fastening of plinths on doors of safety glass, either layered or hardened glass, is a quite delicate operation because an excessively uneven pressure on the glass very quickly results in damage ~hat is inadmissible, even though it is not of a type that would cause the door to be unsafe.
It is also known that an attempt is made, insofar as possible, especially in the case of doors, to apply the fastening element with which the window frames or plinths are held together with the glass panels, such as screws for example, so that they are invisible and thus to make it impossible to disassemble the frame or the door, at least from the outside.
A fastening method is already known for glass panels in metal sections that is more particularly designed to be installed in safety doors, as disclosed in Belgian patent No.
896,386. Although this has seemed quite effective, it does present the disadvantage that it is quite complicated, especially because door plinths in two parts must be used.
The present invention thus also concerns a fastening method for glass in metal sections, however applicant has discovered how these metal sections can be made and used in one piece.
1. ~
~ 61874-736 The invention is an assembly of components for clamp-ing a glass panel, comprising, in combination, a metal section having a tapered groove, tapered inwardly on both sides from top to bottom along its length, a deformable elongate clamping section that fits into the tapered groove of the metal section, an elastic element installed between the clamping section and the outer end of the glass panel such that the clamping section and elastic element engage the glass panel uniformly on both sides, and fastening means for holding the clamping section tight in the tapered groove and moving the same in the tapered groove whereby the outer end of the glass panel, the elastic element, and the deformable clamping section may be inserted into the tapered groove and clamped by movement of the deformable clamping section into the groove.
Advantages of this invention will be apparent from a consideration of the following description and the accompanying drawings in which:
Figure l is a cross section of a fastening element according to the invention;
Figure 2 shows a side elevation of a glass that is provided with the fastening elements according to the invention; and Figure 3 shows a view in cross section along the line III-III in Figure 2.
As shown in Figure l, the fastening element according to the invention consists primarily of a metal section l, a deformable clamping section 2, an elastic element 3 and the glass panel 4 to be clamped in.
The metal section l, which can be either a window frame or a door plinth, is provided with a conical groove 5 along the side along which the glass panel 4 is to be placed, in which case a number of holes 7 that run through to the outside 8 of the metal section 1 are provided in the bottom 6 of the conical groove 5. The metal section 1 can be produced of any metal that naturally is sufficiently sturdy.
The deformable clamping section 2 is preferably U-shaped and has dimensions so that it fits into the conical groove 5 in a clamping manner.
In the bridging part 9 of this U-shaped section a threaded hole 10 is provided so that the clamping section 2 can be drawn downward into the conical groove 5 by means of a bolt 11, as shown in Figure 1.
The elastic element 3 fits around the outer end 12 of the glass panel 4 to be clamped and between the legs 13 and 14 of the U-shaped clamping section 2. In its simplest form the elastic element 3 consists of a flat rubber strip that is slipped around the outer end 12 in assembling the fastening element.
According to another possibility, this elastic element 3 consists, for exmaple, of a U-shaped rubber section that can be slipped over the outer end 12. The elastic elemen~
3 is preferably provided on its free outer end with flanges or collars 15 and 16; they prevent the penetration of moisture into the conical groove 5.
In the case of door plinths the heads 17 of the said bolts 11 are naturally allowed to drop into a recess 18 that is provided in the section 1.
Assembly and disassembly of the fastening element according to the invention can be simply deduced ~rvm ~igure 1. One proceeds as follows during the assembly process.
The U-shaped elastic element 3 is applied over the outer end 12 of the glass panel 4. Then the clamping section 2 3.
1.~9~
is placed over it. Then the metal section is applied, the bolts 11 are inserted through the holes 7 along the outside 18 and screwed into the holes 10 of the clamping section 2. By screwing in the bolts 11, the legs 13 and 14 of the clamping section 2 are moved towara the ~lass panel ~, by which the latter is firmly clamped in.
A safety door is shown in Figures 2 and 3, where the glass panel 4 is clamped into the door plinth 19 by means of the fastening element according to the invention.
According to this embodiment, metal sections 1 are used in the fastening processc They thus form the said door plinths 19, in which the recesses 18 are basically T-shaped, so that these T-shaped inserts 20, which serve as axial bearings, can be installed in a simple manner.
It should be noted here that these inserts 20 or thus the axial bearings can be located in any center oE rotation spacing whatever in that the T-shaped insets 20 are capable of being shifted in the recesses 18 because the latter are in the form of a groove.
According to one variant, the fastening element also contains a handle 21, which preferably consists of a solid bent aluminum rod. This handle 21 also has a safety function during burglary attempts. It holds the two door plinths 19 in position longer when the glass panel ~ has a tendency to bend out after various blows.
It is clear that many variants are possible without exceeding the scope of the invention. For example, different glass panels 4 in which the glass can be lay2red or hardened and have various thicknesses can be used. Different glass panel thicknesses can be handled by using different elastic elements 3.
Of course, both the metal sections 1 and the de~ormable clamping sections 2 can be prepared of different materials.
The present invention is thus by no means limited to the implementations described as examples and depicted in the attached drawings, but such fastening for glass in metal sections can be realized in all sorts of forms and dimensions.
Thus, while we have illustrated certain preferred practices and embodiments in the foregoing specification, it will be understood that this invention may be otherwise embodied within the scope of the following claims.
