Description

(54) MOUNTING FOR GLAZING (71) We, ELTREVA AG, a company organised and existing under the laws of Switzerland, of Hauptstra,sse 107, CH-4147 Aesch, Switzerland, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: The invention relates to a mounting for glazing, such as a sealed double-glazing unit.
A mounting according to the invention comprises a support frame having a Ushaped recess with an inward-projecting lip, and a clamp strip having a foot receivable in the recess and a tab engageable with the lip to lock the glazing in position, the foot being provided with internal camming and retaining means for retaining the tab inside the foot during its removal from the recess.
The clamp strip is preferably of plastics material. Locking tabs are preferably situated at intervals along the clamp strip, and in the operating position before mounting.
The clamp strip fitted with a seal pressure strip, is placed on the support frame in such a way that the foot is received in the recess of the support frame. The clamp strip and support frame are now pressed against each other until the free tips of the locking tabs engage behind the lip of the U-shaped recess.
For deglazing, the locking tabs are pushed back into the foot by means of a screwdriver or similar tool against their elastic spring action to a point where they deflect behind the retaining cam and are fixed in this position. The clamp strip can then easily be removed, and the locking tabs returned to the operating position by inserting a screw-driver through an opening in the foot and pushing them to one side to release them from the retaining cam.
Operation may be improved if the lateral edge of the locking tab corresponding to the retaining cam is off-set sideways in relation to the locking tab and sloped to the face on the retaining cam. It is advantageous for first assembly if a temporary locking cam is provided in a position just in front of the tip of the locking tab.
The retention of the foot in the recess may be improved by porviding both arms of the U-shaped recess with lips to engage the tab and a notch in the foot. With this arrangement it is advantageous for the preliminary assembly if a secondary notch is provided in front of the notch at a distance corresponding to the distance between the tip of the locking tab and the temporary locking cam.
The springiness of the clamp is improved by a reinforcement such as a chromiumsteel inlay which may be moulded under pressure into the body of the plastics material during manufacture.
In the drawings a form of the invention is illustrated by way of example: Figure 1 is a cross section through a mounting with glazing; Figure 2 is an isometric view of a clamp turned through 90 from Figure 1; Figure 3 is an enlarged section along III III of Figure 2 but in the fitted position; Figure 4 is a view like Figure 3 of the position of the locking tab of the clamp at the preliminary assembly stage; Figure 5 is a view like Figures 3 and 4 of the locking tab in its deglazing position; and Figure 6 is a detail D marked in Figure 5 in section along VI-VI.
Figure 1 shows glazing consisting of a support frame 1, glazing 2 and a frame 3.
The frame 3 is connected to the support frame 1 by a clamp strip 4 and presses against the glazing 2 through a seal pressure st-rip 5. The glazing 2 is supported against the support frame 1 by a seal 6 and a block 7.
The clamp 4 is angled in cross-section: an arm 4a engages in the frame 3; the clamps 4 being located at a distance from each other. The arm 4a is shown with a simplified shape in Figure 1 for clarity. A foot 4b of the clamp 4 engages between two U-arms 9, 10 of the support frame 1. These two arms form a recess 8 perpendicular to the glazing 2. The foot 4b is anchored in the recess 8 by lips 11, 12 of the U-arms 9, 10.
Figure 2 shows the clamp reinforced with a chromium-steel inlay 13 and with two flat locking tabs 14 spaced at a distance from each other which can be deflected in relation to foot 4h. In Figure 2 the locking tabs 14 are illustrated in the glazing or operating position, where they protrude from the outer contour of the foot 4b as a result of their elastic spring properties. On the side of foot 4b opposite to locking tab 14, there is provided a notch 15 and a secondary notch 16 for the lip 11 of the inner U-arm 9 of the support frame 1.
Figures 3 and 6 show a retaining cam 17 also provided on the side of foot 4b opposite tab 14, in the area of deflection of each tab 14 and slightly off-set in relation thereto. Figure 6 shows the lateral edge of the locking tab 14 corresponding to the retaining cam 17 as a sloping slide face 14 corresponds to a matching sloping face 17a of retaining cam 17. Figures 3 to 5 show clearly that each locking tab 14 is equipped with a temporary locking cam 18 just in front of its tip which is spaced at the same distance from the free tip of the locking tab as notch 15 is from secondary notch 16 for the lip 11 of the support frame 1.
Assembly of the glazing is carried out as follows: Firstly the frame 3 is equipped with clamps 4 and seal pressure strip 5, and placed on the support frame 1 which has previously been fitted with glazing 2. The locking tabs 14 are in the operating position as illustrated in Figure 2. Applying a slight pressure against the frame 3 normal to the glazing, feet 4b of the clamps 4 are pushed into the recess 8 of the support frame 1, until the lip 11 of the inner U-arm 9 on the one side engages into the secondary notch 16, and the lip 12 of the outer Uarm 10 on the other side engages behind the temporary locking cam 18 of locking tabs 14 (see Figure 4). In this position, the preliminary assembly, the locking tabs 14 are already pressed slightly into the clamp 4.
In this position, alignment of the frame 3 possible. Subsequently, the frame 3 is pressed hard normal to the glazing until the lip 11 of inner U-arm 9 on one side engages the notch 15 and the lip 2 on the other side engages behind a free tip 14b of locking tabs 14, and these tabs, as a result of their elastic spring properties, return to their original position (see Figure 3). This is the final assembly position of the glazing, in which the frame 3 rests under pressure against the glazing 2 via the seal pressure strin 5.
Dissembly is carried out by pushing the locking tabs 14 from the operating position illustrated in Figure 3 into foot 4b of the clamp 4 against their own spring tension by means of a screw-driver or similar tool, thereby causing the lateral slide face 14a of each locking tab 14 to slide up on the sloping face 17a of each retaining cam 17 corresponding to each locking tab. This produces an elastic lateral shift of the locking tab 14 to the point where the tab is located behind the retaining cam 17 and is then deflected back slightly in a lateral direction as a result of the elastic spring pressure, thereby engaging behind the retaining cam 17. In Figure 6, the dimension of this locking action is marked as a and it should generally be smaller than 1 mm. Figures 5 and 6 thus show the locking tab 14 in the deglazing position. The tab may be disengaged from this position by means of a screw-driver or similar tool pushing it right over to one side until it is released from the retaining cam 17 and is deflected back into the operating position as a result of its elastic spring properties.
WHAT WE CLAIM IS: 1. A mounting for glazing comprising a support frame having a U-shaped recess with an inward-projecting lip, and a clamp strip having a foot receivable in the recess and a tab engageable with the lip to lock the glazing in position, the foot being provided with internal camming and retaining means for retaining the tab inside the foot during its removal from the recess.
2. A mounting according to claim 1 in which the edge of the locking tab is provided with a sloping surface corresponding to the camming means.
3. A mounting according to claim 1 or 2 in which the tab has a temporary-locking cam adjacent its tip.

Figure 2 shows the clamp reinforced with a chromium-steel inlay 13 and with two flat locking tabs 14 spaced at a distance from each other which can be deflected in relation to foot 4h. In Figure 2 the locking tabs 14 are illustrated in the glazing or operating position, where they protrude from the outer contour of the foot 4b as a result of their elastic spring properties. On the side of foot 4b opposite to locking tab 14, there is provided a notch 15 and a secondary notch 16 for the lip 11 of the inner U-arm 9 of the support frame 1. Figures 3 and 6 show a retaining cam 17 also provided on the side of foot 4b opposite tab 14, in the area of deflection of each tab 14 and slightly off-set in relation thereto. Figure 6 shows the lateral edge of the locking tab 14 corresponding to the retaining cam 17 as a sloping slide face 14 corresponds to a matching sloping face 17a of retaining cam 17. Figures 3 to 5 show clearly that each locking tab 14 is equipped with a temporary locking cam 18 just in front of its tip which is spaced at the same distance from the free tip of the locking tab as notch 15 is from secondary notch 16 for the lip 11 of the support frame 1. Assembly of the glazing is carried out as follows: Firstly the frame 3 is equipped with clamps 4 and seal pressure strip 5, and placed on the support frame 1 which has previously been fitted with glazing 2. The locking tabs 14 are in the operating position as illustrated in Figure 2. Applying a slight pressure against the frame 3 normal to the glazing, feet 4b of the clamps 4 are pushed into the recess 8 of the support frame 1, until the lip 11 of the inner U-arm 9 on the one side engages into the secondary notch 16, and the lip 12 of the outer Uarm 10 on the other side engages behind the temporary locking cam 18 of locking tabs 14 (see Figure 4). In this position, the preliminary assembly, the locking tabs 14 are already pressed slightly into the clamp 4. In this position, alignment of the frame 3 possible. Subsequently, the frame 3 is pressed hard normal to the glazing until the lip 11 of inner U-arm 9 on one side engages the notch 15 and the lip 2 on the other side engages behind a free tip 14b of locking tabs 14, and these tabs, as a result of their elastic spring properties, return to their original position (see Figure 3). This is the final assembly position of the glazing, in which the frame 3 rests under pressure against the glazing 2 via the seal pressure strin 5. Dissembly is carried out by pushing the locking tabs 14 from the operating position illustrated in Figure 3 into foot 4b of the clamp 4 against their own spring tension by means of a screw-driver or similar tool, thereby causing the lateral slide face 14a of each locking tab 14 to slide up on the sloping face 17a of each retaining cam 17 corresponding to each locking tab. This produces an elastic lateral shift of the locking tab 14 to the point where the tab is located behind the retaining cam 17 and is then deflected back slightly in a lateral direction as a result of the elastic spring pressure, thereby engaging behind the retaining cam 17. In Figure 6, the dimension of this locking action is marked as a and it should generally be smaller than 1 mm. Figures 5 and 6 thus show the locking tab 14 in the deglazing position. The tab may be disengaged from this position by means of a screw-driver or similar tool pushing it right over to one side until it is released from the retaining cam 17 and is deflected back into the operating position as a result of its elastic spring properties. WHAT WE CLAIM IS:
1. A mounting for glazing comprising a support frame having a U-shaped recess with an inward-projecting lip, and a clamp strip having a foot receivable in the recess and a tab engageable with the lip to lock the glazing in position, the foot being provided with internal camming and retaining means for retaining the tab inside the foot during its removal from the recess.
2. A mounting according to claim 1 in which the edge of the locking tab is provided with a sloping surface corresponding to the camming means.
3. A mounting according to claim 1 or 2 in which the tab has a temporary-locking cam adjacent its tip.
4. A mounting according to any preceding claim in which both arms of the Ushaped recess have inward projecting lips, and the clamp is provided with at least one notch for engagement with the lip not engaged with the tab.
5. A mounting according to claim 3 or claim 4 in which a second notch is provided in front of the first a distance the same as that between the tip of the tab and the temporary locking cam.
6. A mounting according to any preceding claim in which the tab is provided with a chromium-steel reinforcement.
