Abstract

In a glazing arrangement a sheet of glass (8) is secured to a frame section (1) by a clip-in glazing strip (3). The glazing strip (3) has two retaining arms (4,5) which engage in a C-shaped groove (2) and, to prevent removal, after the glazing strip (3) has been clipped into place, a locking bar (6) is provided on one (5) of the retaining arms. The locking bar (6) has a T-configuration with an upright portion which engages the floor of the groove (2) and a portion which extends between the retaining arms (4, 5) and prevents the retaining arms moving towards one another. A glass seal (7) can be inserted between the glazing strip (3) and the glass (8) after the glazing strip (3) has been clipped into place. <IMAGE>

Description

SPECIFICATION Glazing arrangement The invention relates to a glazing arrangement in which a frame section has an anchoring groove for receiving and securing a glazing strip provided with resilient retaining arms, which retaining arms extend at a spacing from each other and engage force-lockingly into the anchoring groove, and a glass seal is disposed between the glazing strip and a pane of glass and is fixed to the glazing strip.

In previously proposed glazing arrangements of this kind, after a pane of glass has been fitted into a movable leaf frame made up from the frame sections, the glazing strips are employed to secure the pane of glass in position and to prevent it from dropping out.

Prior to fitting the glazing strips, a glass seal is pressed onto the glazing strips. When the retaining arms of each glazing strip are then pressed into the anchoring groove in the respective frame section, the glass seal is deformed to such a degree that the glazing strip is held in the anchoring groove, under a certain amount of prestressing. The prestressing assists removal of the glazing strip, which is contrary to technical safety requirements in particular when the glazing strip is fitted at the outside of the frame section for example of a window.

In addition, by virtue of the glass seal being fitted into the glazing strip before it is assembled to the frame section, the assembly operation is made substantially more difficult to carry out as considerable forces have to be applied in order to overcome the resistance afforded by the glass seal, when inserting the glazing strip.

According to the invention, there is provided a glazing arrangement comprising a frame section with an anchoring groove therein, a glazing strip provided with resilient retaining arms extending at a spacing from each other and to be engaged force-lockingly into the anchoring groove of the frame section, and a glass seal which is disposed between the glazing strip and a pane of glass and which is fixed to the glazing strip, wherein one of the resilient retaining arms has a locking bar thereon which in the engaged condition of the glazing strip bears against the other of the retaining arms.

in such a glazing arrangement ready release of the glazing strip after the assembly operation has been carried out is no longer possible and insertion of the glazing strip and the glass seal is substantially facilitated.

Preferably the glazing strip cannot be removed without destroying it, after it has been fitted in position.

The retaining arms which are disposed at a spacing in juxtaposed relationship and which are of a resilient nature in order for them better to be fitted into the anchoring groove are mutually held at their spacing from each other by the walls of the anchoring groove on the one hand and by the locking bar on the other hand, so that it is not possible for them to change their position and, as a result thereof, they are prevented from coming out of the anchoring groove.

Precise positioning of the locking bar between the retaining arms is ensured, in accordance with an advantageous embodiment of the invention, if the locking bar is of a substantially T-shaped crosssection, with an upright limb thereof bearing against the floor of the anchoring groove so that the locking bar is fixedly arrested in position with respect to the floor of the anchoring groove and it is virtually impossible for the locking bar to be bent towards the floor of the anchoring groove in the event of the retaining arms possibly being pressed towards each other.

Another advantageous concept of the invention provides that the glazing strip, together with the locking bar, is formed as an integral plastics component, with the locking bar joined to the respective retaining arm in a hinge-like manner by virtue of the material in the joint region being thinner than in the other region.

Providing the glazing strip in the form of a plastics component can considerably facilitate the assembly operation, due to the elasticity of the plastics component.

Assembly of the glazing strip can be facilitated by providing a welt groove in the glass seal, into which welt groove the glazing strip engages, with the glazing strip being formed with a welt portion in the region of its connection the glass seal. The glass seal can be fitted after the glazing strip has been inserted into the frame section.

The invention is diagrammatically illustrated by way of example in the accompanying drawings, in which: Figures 1 to 3 are sectional elevations through a glazing arrangement according to the invention, in successive assembly positions.

Figures 1 to 3 show a frame section 1 with an anchoring groove 2 therein which is of a C-shaped cross-section and is located adjacent a recess which is to receive a pane of glass 8.

For the purposes of arresting and securing the pane of glass 8, a glazing strip 3 is provided having retaining arms or webs 4 and 5 which extend parallel to and at a spacing from one another, the retaining arms 4 and 5 being such that they can be engaged behind short limbs of the anchoring groove 2 in the assembled condition as shown in Figure 3.

Figure 1 shows the position of the glazing strip 3 at the beginning of the operation by which it is fitted.

The retaining arm 4 of the glazing strip 3 which is towards the pane of glass 8 is firstly pressed into the anchoring groove 2, so that it engages behind the undercut region of the anchoring groove.

Formed on the other oppositely disposed retaining arm 5 is a locking bar 6 which is elastically connected to the retaining arm 5 and which extends towards the retaining arm 4. The locking bar 6 is of a T-shaped configuration in cross-section, with the upright limb extending towards the floor of the anchoring groove 2.

In the further phase of the assembly operation for fitting the glazing strip 3, as shown in Figure 2, the retaining arm 5 is also pressed into the anchoring groove 2. When that is done, the retaining arm 5 also engages behind an undercut portion of the anchoring groove 2 while the locking bar 6 bears against the retaining arm 4 by way of its free end which is towards the retaining arm 4, and the upright limb of the locking bar 6 bears against the floor of the anchoring groove 2.

The final position of the glazing strip 3 is shown in Figure 3. In that position, its edge which is remote from the pane of glass 8 terminates flush with the frame section or member 1, while provided at the opposite edge is a glass seal 7 which on the one hand bears against the pane of glass 8 and on the other hand engages over the glazing strip 3 on both sides.

Now, the locking bar 6 of the glazing strip 3 extends between the retaining arms 4 and 5 while the upright limb of the locking bar 6 necessarily extends parallel to the retaining arms 4, 5 and bears against the floor of the anchoring groove 2.

By virtue of the locking bar 6 being in the above-indicated position relative to the retaining arms 4 and 5, the mobility of the retaining arms 4, 5 in a direction towards each other is blocked so that it is impossible for the retaining arms 4 and 5 and thus the glazing strip 3 generally to be released from the anchoring groove 2.

The glass seal 7 is provided with welt-like groove 9 in which a welt portion of the glazing strip 3 engages.

This makes it possible for the glass seal 7 to be inserted after the glazing strip 3 has been fitted in position.

Thus it is possible for the glazing strip 3 to be completely freely inserted into the anchoring groove 2 without, as in the past, having to overcome a resistance which results from the contact pressure with which the glass seal 7 bears against the glazing strip 3 prior to assembly due to its engagement with the pane of glass 8.

By virtue of the described arrangement, both insertion of the glazing strip 3 and fitting of the glass seal 7 are substantially facilitated.
