Abstract

A device for assembling in a window section (1) and in its casement (2) and where this device is a complete glass securing part (11) which is constructed of a glass block (10) and a blocking part 12. The glass securing part (11) and its glass block (10) has resilient lips (4) which engage in grooves (3) of the casement and which, when these lips is snapping in the groove, prevents that the glass securing part can be disassembled. Since the blocking part (12) extends upwards and in front of the lower part of the window section the window section cannot be removed from the casement. With the present device is consequently a protection against simple burglaries obtained, which in some cases are difficult to prove.

Description

DEVICE FOR SECURING A WINDOW SECTION

Present invention relates to a device for secured assembling of a window section in a window casement or in a door section or the like in corresponding frame sections and ac- cording to the preamble to claim 1.

One example of design appears from the description below. The invention is primarily intended for use in combination with a window and its frame. Naturally, the invention can also be assembled in other types of window sections such as doors or other window like sections.

The absolutely new in present invention is the construction of the entire securing part which is assembled in the casement and which after the assembling ensures that the window section not can be disassembled from the casement.

In existing constructions serious weaknesses has been found regarding a protection against inappropriate disassembling of the glass sections from the casement. The constructions has been incomplete designed in a way that occasions has occurred, where a burglary has been done by disassembling a window section, which, after accomplished burglary, is reassembled so that it has not been obvious that somebody has been indoors and caused a damage, a loss of a valuable property.

These inconveniences has been connected with the fact that one window section has only been hold in place in the casement by an outside applied glazing bead 8, which normally only is nailed against the casement with for example a nail punch. This glazing bead is for that reason very simple to disassemble, whereupon the window section has been totally free to remove. Some reinforced protection against this inconvenience is obtained on later constructions by applying silicone glue in the inner side between the window section and the casement, whereupon the exterior glazing bead has been mounted as before. The use of silicone glue leads to an additional cost and often also to a problem of the working envi- ronment, a reason why it still fails, since the access to the window section still is to bad protected.

The object of present invention is to counteract, and as far as possible to eliminate the above mentioned problem. In addition the invention will bring the state of the art in this field forwards in different respects. These objects are achieved according to the invention by a device as is stated in the description and the design of which also is evident from the characteristic part of claim 1. Further characteristics of and advantages with the invention is evident from the following description with reference to attached figures which shows a preferred, but not limited embodiment. In the just showed and described embodiment of the invention, the different figurers represents following:

- Figure 1 is a cross section view of a window section with a mounted complete glass securing part,

- Figure 2 is a design of a glass block, preferably a plastic part,

- Figure 3 is a design of a securing part, preferably a plate part.

Figure 1 shows a cross section view through a casement 2 with a mounted window section 1. The window section can of course include an alternative amount of glasses, but in the embodiment illustrated a 3-glass embodiment is provided. In the casement a dressed groove 3 is provided, preferably located along the whole short side of the casement. This groove is located at a tested distance - 5-15 mm and preferably 10 mm from the interior edge or the interior surface 9 of the casement. The grove has a depth of 2-8 mm, preferably 5 mm and a width of 3-15 mm, preferably 10 mm. In this groove a resilient lip 4 of the glass block 10 is snapping in, when a complete glass securing part 11 is mounted into and between the lower edge 13 of the window and the surface of the casement.

When the complete glass securing part 11 is pushed into its position, the resilient lip 4 and the turned down sections 5 will be snapped down in the groove. The sealing strip 6 which is located on the interior surface 9 of the casement is compressed when the window section is mounted in the casement 2. The force of reaction from this compressed sealing strip is taken up from an exterior glazing bead 8 with an associated sealing strip 7, essentially in the same way as the present constructions of windows, and the tightness of the window construction is therefore completely conventional.

The complete glass securing part 11 has in this position no holding function of the complete window, but constitutes only a securing function in the case when the glazing bead 8 is removed and an attempt to disassemble the window is done.

In the normally assembled position the blocking part 12 is provided in the glass securing part 11 with a certain clearance 22 in horizontal direction, which also is evident from figure 1. Even the resilient lip or lips 4 has a possibility to move a little out of the casement 2 before the lip 4 is stopped by the groove 3 and its vertical wall 26 and all this because the window section will not be subjected to pressure forces from the glass securing part 11 , in this normally assembling position. If required, the opposite side of the casement 2 can of course also be provided with corresponding grooves 3 and accordingly, this side of a window section can also be secured by the glass securing part 11.

In present window constructions spacing blocks, plastic parts is used, which take up the clearance which always must be provided between the glass sections and the inside measurement of the casement, since it is necessary to avoid that the glass is subjected to inherent tensions due to the way of assembling and due to that the casement mostly is made of wood and accordingly, always has an amount of deformation due to temperature and moisture variations.

Thus, in the present invention the glass block 10 is only a part which has been developed compared to present glass blocks and no additional part is added. Thus the excess costs is minimal, since no additional assembling operation is added by the production of a complete window, which depends on the new glass block 10 or the new complete glass secur- ing part 11.

Figure 2 shows the design of the glass block 10.

The glass block is preferably made by casting and it is preferably made of plastic and in this case of a suitable polypropylene or polyamide quality. The glass block is produced with 2 plane sections 15, or legs, which are hold together in a rear section 19. The legs are more or less parallel and 15 has a length of 30-40 mm and a material thickness of 1-3 mm. Preferably the glass block has a width of 100 mm. In one of the legs a number of 1-4 and preferably 2 rectangular holes 16 are made. The position of the holes compared to the common rear and interior wall 17 of the legs 15 is coordinated with that blocking part 12 and those notches or holes 18 which is provided in this part. The rectangular size of the holes 16 is also coordinated with the holes 18. Appropriate dimensions of the holes 16 are preferably 15-30 mm.

The other leg has a number of resilient lips 4, the same number as the holes 16 in the first leg. The lips 4 are directed downwards to the first leg and forwards compared to the rear section 19. The width and length of the lips is slightly smaller than the rectangular dimension of the coordinated holes 16. The angle of inclination of the lips downwards to the first leg is tested and is in the interval 15-60° and preferably 30°.

The material thickness of the lip is larger than the leg^'s own or approximately 1.5-3 times so thick and in addition the lip 4 is underneath provided with a nose 23 and where the nose I situated a distance downwards from underneath the second leg. This distance is coordinated with and only slightly thicker than the material thickness of that blocking part 12 that will be assembled with the glass block 10. The nose extends rearwards to an inner wall 17 of the glass block 10 with a distance of approximately 0.2 - 2.0 mm and preferably 0.5 mm. The lower edge of the nose is situated more or less in the same plane as the exterior side of the first leg and this lower edge extends to a rear side 27 of the lip and then downwards in the same angle as the complete lip 4.

The distance "a" in figure 2b, denotes the distance from the interior wall 17 of the glass block to the front more or less vertical surface 24 above the nose 23. This distance is slightly larger than the distance from the rear edge 32 of the blocking part 12 and to its hole 18, the distance which is denoted as the plate surface 31 in figure 3 and with the di- mension "b".

There are consequently a clearance 22 for the plate surface 31 - see figure 1a. This clearance simplifies the assembling of the blocking part in the glass block. In the normal assembling position, when the blocking part is not loaded with any horizontal force, the blocking part can consequently lay with a clearance in the glass block. However, when the glazing bead 8 is disassembled the force that the compressed sealing strip 6 is giving will be removed to the blocking part 12, and this means that the blocking part with its plate surface 31 will be located in its front position compared to the glass block 10, i.e. in the front, above the nose 23.

The design of the lip 4, according to the above description, gives the lip a stabilizing and reinforcing effect and this thanks to that the blocking part 12 will take a position where the rear edge 28 of the hole 18 in the blocking part will go in beneath the nose 23. When the blocking part 12 is in this position it will stabilize or reinforce the lip 4, so that it obtain a larger bending resistance, if a force is applied and an attempt to draw out the blocking part 12 from its assembled position is made. This means that the complete glass securing part 11 therewith gets a larger strength, a more secure locked position in the assembled position in the groove 3.

To further reinforce the protecting effect with the complete glass securing part 11 the glass block 10 has on respective short side 29 a turned down section 5. This section will prevent an attempt, from the side, to introduce for example a leaf spring or the like between the assembled complete glass securing part 11 and the casement 2 when the glass securing part is assembled in a window section 1. With the leaf spring an attempt could be made to lift up the springs 4 from their engagement in the grooves 3, but owing to, that the glass block 10 has these turned down sections 5, which also extends down in the groove 3, an access to the springs 4 is prevented. The turned down sections 5 have a position and a design on the first leg 15, the one with the holes 16, which are coordinated with the groove 3 in the casement 2 and which implies that the turned down sections always extends below the surface 14 of the casement.

Figure 3 shows the design of the blocking part 12. This part is preferably made of high strength steel.

The main function is, in a quality assured way, to lock the window section 1 in the casement 2, even if the glazing bead 8 is disassembled. The blocking part has to resist considerable drawing forces without moving away from its assembled position. In addition the blocking part has to be designed in a way that it in its assembled position reinforces the strength of the glass block and then especially the bending resistance of the lips 4. Moreover the blocking part has to secure that no pressure arise on the outermost window section, the lower glass section. These functions are obtained by the design which the interacting parts, the glass block 10, the window casement 2, and the blocking part 12, has.

The blocking part 12 is designed as an L with one longer side 20 and one shorter side 21. The side 20 is preferably 30-40 mm long. On this side a number of holes 18 are made. These holes are by dimensions, number and position coordinated with the interacting part, the glass block 10, and this because the lips 4 that are provided in the glass block will be able to spring down and pass the holes 18 when the blocking part 12 is assembled in the glass block 10, which also is described in connection with figure 2. The shorter side 21 is essentially situated at an angel of 90° against the side 20 and has a length of preferably 5-15 mm. In its upper part the side 21 is designed in a special way. The window or window section, which the blocking part 12 has to hold in its position, must be protected from a direct load in its lower exterior corner, the corner around which the blocking part extends.

To manage this, the blocking part is designed in a way that it in its uppermost part 33, preferably on 1-2 mm of its upper part, is located 0.2-1.5 mm rearwards to the longer side 20. Since the radius between the both sides 20 and 21 in addition is small and of approxi- mately the same size as the material thickness of the glass block 10, the window section 1 and its lower or exterior part will not getting in contact with the blocking part 12. The contact will instead be made some mm upwards from the lower or exterior edge of the window section and the contact is then made in the upper part 33 and by this design of the blocking part the window can manage a larger force of impact without damage. In its rear part the blocking part is preferably provided with same art of notch, for example a notch in a V-form, as showed in figure 3. This notch interacts with a corresponding nose 25 which is provided at the glass block 10 and its interior wall 17. By placing these notches/noses off centre the risk of false assembling is eliminated when both parts 10 and 12 are assembled.

An alternative way of production of the complete glass securing part 11 is that the block- ing part 12 is placed in the mould which is used by the production of the glass block 10. Thus, after the casting operation, with this method of production, those both parts will essentially form one single assembled part.

This method bring about that handling and assembling of the both parts, of the glass block 10 and the blocking part 12, 1 simplified, at the same time as the earlier described func- tions in the finished complete glass securing part 11 remind unchanged.
