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.

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

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.
