Description

The invention relates to a mounting strip which has an enclosed cavity and a hook formed on the outside. The mounting strip is part of a frame structure with infilling using plate-shaped elements that are used in sectional door leaves.

With the DE 3 78 296 U1 A door or window made of plastic hollow profile bars has become known. In the case of doors or windows in which the pivot axis essentially coincides with an edge of the sash, for example as a rotating sash, tilting sash or rotating/tilting sash, when the sash is closed, the short leg of the frame profile is advantageously located on the long leg of the stick profile and the long leg of the Frame profile on the short leg of the stick profile. In this way, a double stop is achieved, which is characterized by great tightness. If particular importance is attached to tightness, you can provide a groove on the inside of the long leg that widens as the depth increases and is used to attach sealing strips. By arranging additional retaining strips, it is possible to remove or replace the window pane or door panel at any time. The holding strip can be snapped into the grooves intended for holding it with a longitudinal rib, with the longitudinal rib, when viewed in profile, having a lateral bulge on each side and being beveled by a corresponding amount on the other side, while the groove used to accommodate the longitudinal rib has a lateral groove complementary to the bulge.

Glazing beads for holding a plate that closes an opening, with a base body that has a surface that can be placed on the plate parallel to the plane of the plate and a contact surface with this contact surface Transition area connected, running at an angle to the contact surface, facing the opening in the installed state and with an elastic sealing lip fastened in the opening area and protruding beyond the contact surface in the undeformed state, which can be placed sealingly against the plate DE 198 14 465 B4 again. The transition area is continuously designed as a recess and the sealing lip is fastened in the recess, with the upper edge of the sealing lip lying at its attachment point in the end face and the sealing lip being completely removable into the recess.

A frame component reveals the EP 0 166 414 B1 . The frame component with inserted filling for window or door frames consists of hollow profile bars connected to one another at the corners with ribs preferably arranged on the outside of the frame and a plastic retaining strip inserted subsequently, preferably on the inside of the frame, in particular made of impact-resistant hard PVC, for holding the filling, for example a glass pane, with both the rib and the retaining strip resting against the filling with a flexible seal under prestress, the seal of the retaining strip being co-extruded with it, while the seal of the rib is in a corresponding groove is used and has a high flexibility profile, which is essentially subjected to bending. The seal of the retaining strip consists of a ribbed support on its surface facing the filling, which is essentially subject to pressure and has little flexibility. The seal inserted into the rib is designed as a hollow profile hose. The hollow profile hose is made of synthetic rubber with high elastic flexibility.

The object of the invention is to create an easy-to-assemble and easy-to-dismantle mounting strip for frame formations for panel elements of a sectional door leaf, which can be filled with plate-shaped elements. Such When assembled, the mounting strip should have large pressure forces against the plate-shaped element and thereby ensure that the plate-shaped element is fastened in a watertight and windproof manner and should also be replaceable if necessary. Furthermore, a frame design for such a mounting strip should be provided.

The object of the invention is achieved by the features of claim 1 for a mounting strip and a frame design according to claim 7. The subsequent subclaims reflect a further embodiment of the idea according to the invention.

Sectional doors consist of individual elements, the panel elements, which are connected to each other so that they can rotate. There are rollers on the side of the elements so that the sectional door leaf can be moved in conjunction with stationary guide rails. While in the past sectional doors were essentially perceived as closed panel elements, the structure of the individual elements has increasingly changed. The change essentially consists of the fact that instead of the individual panel elements for the sections that are normally foamed between cover layers, open viewing windows are now created through circumferential frame formations. These fields of view are preferably filled with plate-shaped elements, for example made of a transparent plastic or the like. For assembly and disassembly in the event of damage to these fields of vision, it is necessary that the plate-shaped elements must be quick and easy to replace. This can be achieved using a mounting strip made of an impact-resistant plastic with a high Shore hardness.

Such a mounting strip has a cavity that is enclosed on all sides and has a protruding hook on its underside base. The mounting strip engages with this hook in an open recess Frame formation for the panel element of the sectional door leaf. The mounting strip forms a positive connection with the plate-shaped element used in the frame formation and the frame formation, at least in the assembled state.

The mounting bar has a bottom support surface under the cavity that is part of a base formed in front of the hook. When assembled, the support side of the retaining strip is in contact with the frame formation. The design of the hook creates two different sections with a high preload relative to the plate-shaped element on its contact side. It is important that only materials that are not subject to embrittlement are used for the mounting strip, otherwise the holding forces compared to the plate-shaped element would decrease over time. This means that the adhesive forces on the plate-shaped element must be present permanently and thus a high level of stability and elasticity must be guaranteed. For this reason, the mounting strip is made of an impact-resistant plastic with a high Shore hardness or of light metal.

In a further preferred embodiment, the mounting strip on the side that is positioned against the plate-shaped element can also be provided with sealing lips. These can be carried out, for example, using a two-component technology, which is carried out using an injection molding process in one operation, but with strictly separate component areas. By using such additional sealing lips, a long-lasting, good sealing result is achieved, even under high loads and different material combinations. By combining thermoplastic plus elastomer, ie plastic and rubber, complex assembly and post-processing for sealing using additional materials can be avoided.

In order to be able to use such a mounting strip within a frame, there is a support side on the bottom, which is delimited by a first section with a hook design. This means that the hook does not only have a straight slope, as in the prior art. On the first section after the support side, the hook formation runs at an angle greater than 90°. This first section is followed by a second section, which is formed at a different angle, but which is aligned in the direction of the contact side. At the end of the two angled sections of the hook there is also a protruding contact point which is positioned against a contact wall within the frame.

In order to be able to carry out the assembly and correct seating of the mounting strip within the frame formation, there is a support area on the underside in the area of an outer wall of the holding strip, which is essentially point-shaped.

The invention is explained in more detail below using two preferred exemplary embodiments:

Figure 1

shows a cross-sectional view of a first preferred embodiment of a mounting strip;

Figure 2

in the Figure 1 mounting strip shown in use in a frame training;

Figure 3

another preferred embodiment of the mounting strip with additional sealing lips.

A first preferred embodiment of a mounting strip 1 is that Figure 1 again. The mounting strip 1 has a cavity that is closed on all sides 6, which is delimited on the outside by an outer wall 4 and on the inside by a contact side 3, as well as a top partition 5 and a bottom base 7. When installed, the system side 3 has contact with a plate-shaped element, which is used in a frame formation 2 as a panel element within a sectional door leaf. The contact side 3 must apply the necessary pressure against the plate-shaped element, because no water entry from outside must be possible between the contact side 3 and the plate-shaped element. This can be achieved in particular by making the mounting strip 1 from an impact-resistant plastic with a high Shore hardness, which nevertheless ensures a high contact pressure and simultaneous adhesion to the plate-shaped element.

The base 7 of the mounting strip 1 essentially consists of the straight contact side 9, an adjoining hook 22 and an adjoining side 8 with a bevel, which ends in an external support area 11. While the support side 9 and the outer support area 11 are at the same height, the side 8 with the bevel extends in the direction of the hook 22, starting from the outer support area 11. This bevel of side 8 is essentially in a range of 1° to 10°.

The hook 22 is divided into a first section 10 and a second section 12. The first section 10 of the hook 22 is designed to reject the essentially straight support side 9 by an angle between approximately 91 ° and 110 °. Following this first section 10, the second section 12 is again formed in the direction of the support side 9, with this angle, starting from the first section 10, being approximately between 40° and 50°. At the end of the second section 12, a projecting contact point 13 is formed with a section 23 on the underside, which runs approximately parallel to the contact side 9.

The ones in the Figure 1 Mounting strip 1 shown is in the Figure 2 shown in cross section within a detail view of the frame training 2. The sections 10 and 12 of the hook 22 are immersed within a receiving space 16 that is open at the top. On the one hand, the support side 9 rests on a support 24 of the frame profile 2. At the same time, the outer support area 11 of the mounting strip 1 has contact with a support 15 of the frame profile 2. As a continuation of the support 15, a second counter bearing 20 with a first counter bearing 19 is formed under an inclined position, facing away from the mounting profile 1. While the outer support area 11 has contact with the second counter bearing 20, the first section 10 of the hook rests laterally against the first counter bearing 19 of the frame formation 2. Due to the inclined position of the second section 12 of the hook 22, it comes into contact with a contact wall 18 and its contact point 13 at the end within the receiving space 16 as a continuation of an inclined inner wall 17. The sloping inner wall 17 runs in the direction of the opening of the receiving space 16. This ensures that the mounting strip is unintentionally removed from the receiving space 16.

This type of construction ensures that the mounting strip 1 can be given a secure and permanent hold by being designed with multiple contact areas. The frame formation 2 has a frame profile outside 14 on the outside, which is essentially aligned with the outer wall 4 of the mounting strip 1 after the mounting strip has been used.

In the Figure 3 Another preferred exemplary embodiment is shown. In this exemplary embodiment, the mounting strip 1 was additionally provided with sealing lips 21 on the contact side 3. These sealing lips 21 have a lower Shore hardness than the mounting strip 1 itself. This means that the two components of the mounting strip 1 can be produced in an injection molding process in one operation, with the contact side 3 with the sealing lips 21 made of a thermoplastic and the rest made of an elastomer.
