Definitions

  • the invention relates to a window element comprising a frame, a window pane and a plurality of clamping elements, the window pane having two opposite pane surfaces which are accessible from the outside and a peripheral edge with a plurality of peripheral sides, the window pane being fastened to a frame stop of the frame in an edge region of the pane surface facing the frame frame is in contact, wherein a plurality of clamping elements spaced apart from one another can be introduced along the peripheral sides of the window pane between peripheral surfaces of the peripheral sides of the window pane and an inner peripheral surface of the frame in an assembly direction oriented perpendicularly to the pane surfaces and the window pane rests against the clamping elements within the frame, with the Clamping elements, a defined gap between the peripheral surfaces and the inner peripheral surface of the frame is generated, wherein in the through the clamping elements between the peripheral surfaces and the inner peripheral surface the gap created by the frame is filled with adhesive and the window pane is connected to the frame in a force-fitting and material-locking manner along the peripheral sides.
  • window frame When building windows, the term window frame includes both a frame that is fixed to a wall and a frame that is movably attached within the frame sash frame understood.
  • the sash frame can be rotated, folded, turned, pushed and/or swung.
  • window frame and frame are used both for the window frames described above, such as the window frame and casement frame, and for window elements that are installed in balcony doors.
  • a window element consisting of a window pane and a window frame is installed by inserting the window pane into the window frame and fixing it in it by what is known as blocking.
  • the edge area of the window pane is brought into contact with the so-called glazing rebate arranged on an inner peripheral surface of the window frame.
  • a pane surface of the window pane rests against the frame via a seal on a side of the window pane that faces the pane surface.
  • flat clamping elements also known as pads, are introduced between the peripheral surface of the window pane and the inner peripheral surface of the window frame.
  • the rectangular clamping elements usually have a thickness of a few millimeters and, depending on the thickness of the window pane, a length and width of a few centimeters.
  • support blocks which are introduced between a peripheral side of the window pane pointing downwards and the inner peripheral surface of the window frame.
  • Those between the lateral peripheral sides of the window glass and the inner peripheral surface of the window frame inserted spacers are used to secure the position of the window pane within the window frame.
  • Stabilization of the window frame is achieved by the mounting of the window pane on the clamping elements, which is produced by the blocking.
  • the clamping elements are usually made of plastic, such as polypropylene (PP).
  • a gap between the peripheral surface of the window pane and the inner peripheral surface of the frame is pried open by means of a lever tool, a so-called trowel.
  • the clamping elements are then pushed into the gap by hand and the lever tool is then pulled out of the gap again.
  • the window frame thus rests against the peripheral surfaces of the window pane.
  • the gap created by the lever tool should be a few millimeters larger than the thickness of the clamping element for inserting the clamping element.
  • the window panes can also be insulating glazing.
  • Insulating glazing consists of at least two panes of glass combined to form a component for windows and other glazing. There is a cavity between the glass panes that is sealed against gas and moisture. The cavity is also used for sound and heat insulation.
  • the window pane instead of blocking the window pane within the frame, it is also known to glue the window pane in the edge region of the window pane over the pane surface and over the peripheral surface to the frame stop and to the inner peripheral surface of the window frame.
  • the adhesive connection achieves an overall higher stability of the window frame, since the adhesive connection creates a firm connection between the window pane and the window frame and the window pane itself can absorb forces and thus contribute to the stabilization of the window frame or the window element.
  • a uniform adhesive connection between the window pane and the window frame is essential for a uniform load transfer of the weight forces of the window pane to the window frame.
  • a uniform distance between the peripheral surface of the window pane and the inner peripheral surface of the window frame must be produced before the adhesive is applied. Such an alignment is usually adjusted via the clamping elements described above.
  • the clamping element has a bay-shaped recess which is open in the opposite direction to the mounting direction and which can be filled with adhesive, so that in the region of the bay-shaped recess the adhesive introduced can be used to create a material connection between the peripheral surfaces of the window pane and the inner peripheral surfaces of the frame .
  • a particularly large proportion of the peripheral surfaces can thus be glued to the inner peripheral surfaces, so that a particularly good transmission of force can take place between the window pane and the frame.
  • the adhesive can be introduced into the gap created by the clamping elements between the peripheral surface of the window pane and the inner peripheral surface of the frame in order to create a continuous adhesive connection there.
  • the clamping element has two tongues delimiting the bay-shaped recess, the tongues pointing counter to the assembly direction and the end regions of the tongues are rounded. Due to the rounded configuration of the tongues, the adhesive can flow particularly well around the rounded end area of the tongues during an application of adhesive.
  • the indented recess of the clamping element can thus be filled up particularly well with adhesive.
  • the areas around the clamping element are thus filled particularly well and evenly with adhesive. A particularly uniform adhesive connection can thus be produced between the window pane and the frame, which leads to a high degree of stability of the window element.
  • the tongues have a continuous recess oriented perpendicularly to the assembly direction.
  • the clamping element has at least one spring element, the spring element having a free end of the spring element that projects perpendicular to the direction of assembly has, wherein the free end of the spring element is oriented in a direction opposite to the direction of assembly.
  • the spring elements can also compensate for changes in distance between the peripheral surfaces and the inner peripheral surface without the inserted spring element slipping and the alignment being changed. Because the free end of the spring element is oriented in a direction opposite to the direction of assembly, the clamping element can be pushed into the gap in a particularly simple manner. In addition, as a result, an installation direction of the clamping element is specified, so that incorrect assembly can be prevented.
  • the mounting direction can also be depicted on the surface of the clamping element, for example by an arrow pointing in the mounting direction.
  • the clamping element is hollow-shaped and has cavities, the cavities being accessible via cavity openings oriented opposite to the direction of assembly.
  • the cavities can thus also be filled with adhesive, so that an adhesive connection between the window pane and the clamping element and between the clamping element and the frame can be produced with almost no gaps. A particularly large-area adhesive connection can thus be produced.
  • the spring elements are formed within the recesses of the tongues, with a width of the spring elements being smaller than a width of the recess.
  • an adhesive bond can be formed between the peripheral surfaces and the inner peripheral surfaces of the frame by the adhesive running through the recess of the clamping element.
  • an assembly tool which has a receiving area which is open in the assembly direction, the assembly tool having two clamping fingers which are arranged laterally with respect to the receiving area.
  • the receiving area is designed in such a way that a clamping element can be received in the receiving area between the clamping fingers and fastened in a non-positive manner.
  • the assembly tool can also have a handle. The clamping element can thus be introduced into the gap between the window pane and the frame in a particularly simple manner using the assembly tool.
  • a gap between the peripheral surface of the window pane and the inner peripheral surface of the window pane is usually created with a lever tool, a so-called trowel, in order to be able to insert the clamping elements into the gap thus created.
  • a lever tool a so-called trowel
  • an advantageous embodiment of the assembly tool according to the invention provides that the thickness of the clamping fingers of the assembly tool is smaller than the thickness of the clamping element.
  • the assembly tool that is not in contact with the window pane and the frame can also be pulled out of the gap after the trowel has been pulled out of the gap, with the clamping element frictionally clamped between the window pane and the frame remaining in the gap.
  • the clamping fingers of the assembly tool prefferably be designed to taper in the direction of assembly, with the thickness of the clamping fingers being designed to decrease in the direction of the direction of assembly.
  • a Thickness of the clamping fingers is at least partially greater than a thickness of the tongues of the clamping element, so that when the assembly tool is inserted, the clamping fingers of the assembly tool and only the projecting spring elements rest against the peripheral surface of the window pane within the gap.
  • the spring elements are dimensioned so that the spring force generated is so great that a non-positive connection between the clamping element and the window pane or the frame is stronger than the non-positive connection between the clamping element and the assembly tool. The clamping element is thus supported with the spring elements against the window pane and the frame and also remains in the original position while the assembly tool is being pulled out.
  • an advantageous embodiment of the assembly tool provides that the assembly tool has a stop surface in the receiving area, which is designed as a shoulder oriented perpendicularly to the assembly direction. wherein the stop surface can be brought into contact with the pane surface of the window pane after the insertion of the clamping element and the assembly tool into the gap between the window pane and the frame.
  • a defined orientation of the clamping element relative to the pane surface is achieved by the contact of the shoulder, which is oriented perpendicular to the assembly direction, with the pane surface of the window pane.
  • the clamping element can be particularly advantageous in one reproducible depth and orientation are introduced into the gap.
  • the task stated at the outset is also achieved by a method in which the window pane is placed in the frame in an assembly direction facing the frame, the window pane having two opposite pane surfaces which are accessible from the outside and a peripheral edge with a plurality of peripheral sides, the window pane being in an edge region of the pane surface facing the frame in the assembly direction is brought into contact with a frame stop of the frame, wherein in a subsequent clamping step, using the assembly tool, a plurality of clamping elements are introduced at a distance from one another along the peripheral sides of the window pane between peripheral surfaces of the peripheral sides of the window pane and an inner peripheral surface of the frame , So that the window pane rests against the clamping elements within the frame and a defined gap is generated between the peripheral surfaces and the inner peripheral surface of the frame, wherein in an ansch gluing step, an adhesive is applied in an adhesive application direction oriented towards the frame into the gap created by the clamping elements between the peripheral surfaces and the inner peripheral surface of the frame and the window pane is connected to the frame along the
  • the clamping step Assembly tool is inserted into the gap until the stop surface rests against the pane surface of the window pane, so that the clamping element introduced into the gap by means of the assembly tool assumes a defined position between the peripheral surfaces and the inner peripheral surfaces.
  • the clamping elements can thus be introduced into the gap in a particularly advantageous manner at a reproducible depth and orientation, and a uniform adhesive connection between the window pane and the frame can be ensured across the clamping elements.
  • an advantageous embodiment of the idea of the invention provides that during the gluing step the adhesive is applied in the adhesive application direction along the edge region of the window pane, so that the adhesive introduced into the gap at least partially extends beyond the gap is designed as an adhesive track and an integral connection can be produced between the pane surface of the window pane in the edge region of the window pane and the frame stop of the frame.
