Abstract

The present invention relates to a fastening means for a lens, which is deformed during the assembly process.

Description

The present invention relates to the glazing of windows used in buildings.

Windows have a very big impact on the energy losses of buildings. They are an important starting point in the course of a so-called energy renovation, because windows are sometimes designed as glazing with high heat losses. Due to this fact, energy is lost. According to the state of the art, the replacement of complete windows or their glazing is intended to improve the situation. The aim of such an exchange is to reduce heat losses through reduced heat transfer through so-called multiple glazing.

An exchange is associated with the loss of bound energy, i.e. energy that was tied up in the production of the windows and glazing that are now being exchanged. This is an adverse circumstance.

After replacement, the removed windows and glazing must be disposed of, which puts a strain on the infrastructure (landfill and/or recycling) and therefore represents a further disadvantage.

Depending on the market situation, the availability of materials (windows, glazing) is not always guaranteed and can result in high costs.

Another disadvantage in some cases is the availability of craftsmen. Coordinating appointments and sticking to deadlines can sometimes be a challenge. High costs can be incurred and the usability of rooms is only limited or not possible at all while the craftsmen are working. These are further disadvantages that speak against replacing windows or their glazing.

To eliminate these disadvantages, so-called additional washers have been proposed. Such attachment discs are, for example, in DE9013167U1 , EP0152885A2 , DE7719752U1 , DE7930473U1 and DE958248C described.

DE9013167U1 and DE7930473U1 suggest attaching the additional pane to the glass frame of a window. The attachment of the lens is fixed to the glass frame using a Velcro fastener or screws. If dismantling is necessary, both leave traces that require considerable effort to remove.

In the case of Velcro, it is difficult to attach and remove. In the case of attachment, alignment is difficult. In the event of loosening, the circumferential loosening of the Velcro fastener without inadvertently re-sticking is a challenge. In addition, the adhesive strength competes with the adhesive security. Furthermore, if reversibility is desired, the Velcro fastener, which is also on the side facing away from the old glass, is visually and haptically disturbing.

In the case of fastening with screws, expansion of the attachment pane due to the absorption of moisture - which is particularly the case with plastic glass - is not compensated for. This leads to denting of the lens or damage to the lens or fastening. Damage can also occur when fastening the additional washer due to excessive screw tightening torque. The choice and application of the correct screw tightening torque is usually reserved for a craftsman.

EP0152885A2 and DE7719752U1 provide for the attachment of the additional pane by gluing it to the existing glass. Installation is difficult here, as is dismantling if cleaning or complete removal is necessary.

DE958248C carries out the attachment to the glass frame using so-called sashes. These are screwed into the glass frame and thus cause damage.

In many cases, the residents of an apartment are not the owners and therefore cannot influence the inventory at their own discretion. This means you cannot arrange for an exchange or make any changes that cause damage to the rental property. This is a major disadvantage of the current state of technology.

If the residents of an apartment are also its owners, the replacement of windows with windows with reduced heat transfer is encouraged, depending on the law. At the time of writing, funding will only be granted if the external walls of the building to be funded have a lower heat transfer compared to the windows. This is to prevent the inside of the building from hitting the otherwise colder outside walls

Moisture settles and mold can form. This means that owners are forced to insulate the outside walls before taking action on the windows. This can cause very high costs and lack of availability of materials and hands worker capacity prevent feasibility. The availability of a cost-effective, simple option for equipping with additional windows is therefore desirable because it means that a building can be optimized energetically even without funding if the users design their ventilation behavior accordingly.

Attachment panes, which are provided with pre-drilled holes to accommodate screws to simplify installation, require corresponding preparations for installation on the existing window. The positioning of these corresponding preparations requires a high degree of dimensional accuracy and is usually reserved for a specialist, i.e. a craftsman. If drilling is required, special tools such as drills, drilling machines, measuring tools and knowledge of their use are generally required. This is an adverse circumstance.

Furthermore, drilling holes in an attachment pane causes increased costs and the risk of the attachment pane breaking.

The object of the present invention is to avoid or at least reduce the disadvantages described and to create a cost-effective, simple and quick option for equipping with an additional pane. The solution to the problem uses an arrangement with the features of patent claim 1. Advantageous embodiments result from the dependent patent claims.

Accordingly, a fastening means for an attachment pane is provided, which is characterized in that a section of a fastening means of the attachment pane is deformed during assembly.

The fastener is attached to the old glass of a window element using an adhesive (double-sided adhesive tape or self-adhesive coating with concealing protective tape, which is removed before installation).

A sealing element can also be fixed to the old glass using adhesive. This sealing element is positioned on the old glass so that it rests on the frame that holds the old glass. The sealing element is therefore arranged between the front pane and the old glass.

The end customer orders the front pane from a manufacturer/dealer according to the dimensions of his old glass stock. The manufacturer/dealer supplies the end customer with the dimensionally prepared lens, as well as fasteners, sealing elements and adhesives.

The installation of the additional window is usually carried out by the end customer themselves. The end customer can be a layperson.

The end customer bends the fastener from the flat state to the folded state. This is easily possible because the fastening means has openings along a first bending line.

After cleaning the old glass, the end customer sticks the fasteners along the frame in the required number to match the dimensions of the pane on the clean and grease-free surface.

In a next step, the end customer - if not already done by the manufacturer/dealer - cuts the sealing element to the required length and fixes it along the frame, which holds the old glass, using an adhesive.

The process of bending, cutting and gluing is a simple process and can be done without any training.

After attaching the fasteners and the sealing element, the additional pane, prepared in dimensions by the supplier, is placed on the lower section of the frame, which surrounds the old glass, and tilted towards the sealing element.

Advantageously, at least 3 mm of clearance is provided on the sides and at least 6 mm on the top and is retained when cutting the additional pane.

For fixation, an upper section of the fastening means is subsequently bent along a second bending line against the attachment pane. This results in a simple, cost-effective and tolerance-insensitive fixation of an attachment pane.

If necessary, dismantling can be carried out very easily if the space between the panes needs to be cleaned. To do this, the upper section of the fastener is bent back along the second bending line and the attachment disc is removed. After cleaning, the front pane is reattached in the manner already described.

In order to be able to carry out the bending process several times without damaging the fastener, it is made of a metallic material guided. Low-cost, low-alloy steel or aluminum materials in a soft state are preferred.

To simplify bending back, provision can be made for a front section to be provided on the upper section of the fastening means, which can be bent slightly away from the attachment pane. This makes it easier to attack during dismantling.

If the need arises for a complete retrofit to the condition before the attachment of the front pane, the dismantling described is carried out and the sealing element is then removed from the old glass. The same thing happens with the fastener. Any remaining adhesive residue is removed using standard household tools. No further specialist knowledge is required.

In a further embodiment of the invention, a sealing element can be dispensed with. In this case, the fastening means provides a support surface for the lens.

The openings along the bending lines of the fastener reduce the heat transfer and are therefore advantageous because they reduce the heat losses that arise from the use of a metallic material.

In a further development of the invention, elastic deformation can be used as an alternative to the plastic deformation of materials to solve the inventive problem. Plastics are also suitable here. The fastening means is designed in the form of a resilient locking mechanism. During the joining process, the resilient fastening means is deflected by the attachment pane. When the end position of the attachment pane is reached, the fastening means springs back and locks the attachment pane. To remove the attachment pane, the fastening means is deflected manually and the locking mechanism is released, allowing the attachment pane to be removed.

The figures are exemplary and schematic. The same reference numbers in the figures stand for the same functional and/or structural features.

1 shows an arrangement according to the invention with window (1) and frame (2). Sealing elements (4) and an attachment disk (5) fixed by fastening means (6) are also shown. The attachment pane (5) rests on a frame (2) with a lower surface (12). Its upper surface (13) is at a distance from the frame (2) to make assembly easier and to accommodate expansions and tolerances. The side surfaces (14) of the additional pane (5) are also at a distance from the frame (2) to facilitate assembly and to accommodate expansions and tolerances. Advantageous values can be found in one of the previous sections.

2 shows the schematic representation of a window (1). 1 in a horizontal section with a first embodiment of a fastening means (6) according to the invention. An old piece of glass (3) is held in a frame (2). Between old glass (3) and/or a lower section (10). A sealing element (4) is arranged between a fastening means (6) and an attachment pane (5), which surrounds a space between the panes (8) and creates a distance between an attachment pane (5) and an old piece of glass (3). At least one fastening means (6) is arranged on this old glass stock (3) close to the frame (2) and surrounds an attachment pane (5). The joining direction (23) for the additional pane (5) points in the direction of the old glass (3).

3 shows a first embodiment of a fastener (6) in the folded state. Shown is a lower section (10) and a first bending line (17) in which openings (7) are located. A middle section (11) extends approximately perpendicular to this, bounded at the top by a second bending line (18) with openings (7). An upper section (15) extends approximately perpendicular to the middle section (11) and approximately parallel to the lower section (10).

4 shows a first embodiment of a fastener (6) in a flat state in a preferred embodiment. A lower section (10) is delimited by a first bending line (17) on which there are two openings (7). This is followed by a middle section (11), bounded by a second bending line (18) with three openings (7). This is followed by an upper section (15). What is characteristic of this preferred embodiment is that the total length of the openings (7) on the second bending line (18) is longer than the total length of the openings (7) on the first bending line (17). This ensures that after bending around the first bending line (17) there is no significant change in the angle between the lower section (10) and the middle section (11) when bending around the second bending line (18).

5 shows a schematic representation of a fastening means (6) in a second embodiment in the folded state. In addition to 3 Here, the fastening means (6) has a front section (16) which is tilted slightly upwards along a third bending line (19) with openings (7) compared to an upper section (15). Access to opening is thus made easier if, in the assembled state, there is an attachment disk (5) - not shown here - below the upper section (15) and adjacent to it.

6 shows a schematic representation of a fastener in a third embodiment in the folded state. Different than in 3 Here the fastening means (6) has a locking section (21). This is achieved by having the second bend line (18) perpendicular to the first Bending line (17) runs. When folding around the second bending line (18), the locking section (21) extends over an attachment disk (5) - not shown here - and thus limits its mobility against the joining direction (23).

7 shows a schematic representation of a window 1 in a detail section with a fastening means (6) in a first embodiment in the folded state. The fastening means (6) is fixed near the frame (2) by an adhesive (9) with its lower section (10) on an old glass stock (3). A sealing element (4) is attached to the fastening means (6) via a sealing element adhesive (22) and thus creates a distance between the old glass (3) and the attachment pane (5). Sealing element (4), attachment pane (5) and old glass (3) form a space between the panes (8). The mobility of the attachment disc (5) is limited by the upper section (15) of the fastening means (6). This ensures a permanent existence of the space between the panes (8).

8th shows the situation of 7 and additionally a front section (16) on the fastening means (6). This makes it easier to bend open the upper section (15) thanks to better application of force when the attachment pane (5) is to be removed.

9 shows a schematic representation of a fastening means (6) in a fourth embodiment in the folded state. In addition to 3 Here, the fastening means (6) has a support surface (20) for an attachment disk (5), not shown. In interaction with an upper section (15), a fixing of an attachment disk (5), not shown, is achieved with respect to a joining direction (23).

10 shows the schematic representation of a window 1 in a detail section with a fastener in a fourth embodiment 9 . The fastening means (6) fixes an attachment disk (5) between the support surface (20) and the upper section (15) against a joining direction (23).

11 shows further training from 4 . The openings (7) are designed in the form of half-open slots. The slots along the second bending line (18) are preferably longer. This ensures that after bending around the first bending line (17) there is no significant change in the angle between the lower section (10) and the middle section (11) when bending around the second bending line (18).

12 shows additional training from 4 . The openings (7) are designed in the form of round openings.

13 shows a schematic representation of a window 1 in a vertical section with a bending-elastic fastener (24). An old piece of glass (3) is held in a frame (2). A sealing element (4) is arranged between the old glass (3) and/or a lower section (10) of a fastening means (24 and 6) and the attachment pane (5), which surrounds a space (8) between the panes and a distance between the attachment pane (5) and old glass stock (3). At least one fastening means (6) is arranged on the old glass (3) close to a frame (2) and surrounds an attachment pane (5) in the lower area. If, during assembly, the attachment washer (5) is placed in the lower area between the fastening means (6) and the sealing element (4) and moved in the joining direction (23), it deflects the locking element (25) in the direction of an elastic bend (26). Once the attachment disc (5) has come into contact with the sealing element (4), the locking element (25) is released again and returns to its starting position. To disassemble, the locking element (25) is deflected manually and the additional disk (5) can be removed.

The features of the invention disclosed in the foregoing description, in the claims and in the drawings may be essential both individually and in any combination in the realization of the invention in its various embodiments.
