EP3477033B1 - Profile system with clamps and method for mounting a profile system - Google Patents

Description

The present invention is concerned with a window or door profile system which can be used to cover frames and in particular to offer protection from the elements.

BACKGROUND

In addition to metal and plastic profiles, wood is also traditionally used in window and door construction. While the wood can be left untreated on the side facing the interior, weather protection must be applied on the side exposed to the weather. This must cover several sub-areas, considered here using the example of the lower horizontal closure: The area of the masonry opening that is not covered by the window or door frame is usually bridged by a door threshold or a window sill in order to prevent water from penetrating the wall prevent. In the case of wooden profiles, the frame itself has to be provided with protective coatings or is covered with a profile, which in turn is often made of metal or plastic - hereinafter referred to as the basic profile. The transition area, the joint between the frame and the masonry opening is often bridged with a so-called weather bar. This is understood to be an angled panel in the broadest sense, which on the one hand connects to the basic profile and bridges the gap to the window sill / door sill. In order to compensate for installation tolerances and at the same time not generate any need for individual adjustment, weather strips are designed as elements that can be flexibly attached to the basic profile.

STATE OF THE ART

Basic profiles with weather strips are already known in the prior art. They have the inevitable disadvantage that the base profile must be attached to the frame, which is traditionally done with nails, screws or staples. For some of these fasteners, pre-drilled holes or markings for setting points must be made in the base profile, and assembly must be carried out with care because the fastenings can be visible when the window / door is open. Sliding drills or setting tools can cause damage that is laborious to conceal or repair - if at all.

The frames themselves are often provided with profiles, i.e. with grooves, webs, folds or ribs, which serve as stops, sealing edges and fastening points. These profiles are machined into the frame components.

The document EP 3 043 016 A1 shows a mounting profile (mullion rail 5) for door or window frames, which is arranged between the frame and the masonry. The mounting profile also has a centering aid (groove 22) in which a clip 11 engages and thus facilitates the alignment of the frame (frame 21) on the mounting profile.

The disclosure document WO 2006/095201 A1 shows a combination of a window sill or threshold element and a weatherboard, which is also arranged between a brickwork and a door or window frame. A cladding is achieved by a clipping strip.

The font DE 198 59 166 A1 shows a composite profile for windows or doors with a first profile to be fastened to an existing frame and a second profile snapped on by means of clips. A weatherstrip can be adjustably arranged on the second profile.

It is therefore the object of the present invention to propose a window or door profile system which can fulfill the aforementioned tasks and, moreover, allows a simplified, quick and secure attachment option between the base profile and the frame.

DESCRIPTION OF THE INVENTION

This object is achieved by a window or door profile system with the features of independent claim 1. An assembly method is described from claim 5.

Sub-claims describe further useful variants.

Contrary to the traditional view that a base profile has to be screwed, nailed to the frame or fastened with staples, the present invention succeeds in creating a secure connection with the aid of a retaining clip. The assembly can be done largely without tools and in any case without the use of mechanical connectors or fasteners such as screws, nails or staples. In the present description, the term "invasive mechanical fastening means" is used for this purpose. "Invasive" means all fasteners that have to be driven into the frame / frame profile (that is, penetrate its surface), that is, transfer forces directly into the interior of the frame.

A window or door profile system according to the present invention comprises at least one basic profile with a fastening position for a weatherboard. The term “fastening position” means an interface, a connection or fastening point that allows or facilitates the connection between the base profile and the weatherboard. The basic profile is attached to a frame provided for this purpose only by means of a large number of retaining clips without additional invasive mechanical fastening means such as screws, nails or staples. With frames are meant components that are firmly connected to a building opening or surface into which e.g. Windows or doors can be inserted.

In one embodiment, the fastening position for the weatherboard is designed as a longitudinally extended, essentially cylindrical connecting element, which allows the weatherboard to rotate about the longitudinal axis of the connecting element. For this purpose, the cylindrical connecting element preferably has an axially elongated groove.

According to the invention, the retaining clip, which can be used in said profile system, is designed as a one-piece stamped and bent part. It can be described as a U-shaped bracket in cross section with a base and a first and a second leg. The legs should not be understood exclusively as being "linearly shaped". The angles between the base and legs are not necessarily set at 90 °.

According to the invention, the first leg essentially comprises a first spring element:. This is achieved in that the first leg has a longitudinal fold with a kink angle δ, which divides the leg into a first leg section and a second leg section. From a technical point of view, the first leg thus has two surface areas or leg surfaces which are arranged at an angle to one another. The crease is oriented parallel to the general longitudinal direction of the retaining clip.

The retaining clip is also designed such that the interior angle γ between the base and the first leg section is less than 90 °. In other words, the first leg section is more inclined towards the base, quasi the interior of the U.
As a result, the spring action of the first spring element in the mounted state enables a holding force on the frame or a profile rib of the frame that corresponds to the shape of the U-bracket.

Similar to the first limb, the second limb also has two flat limb regions which are arranged at an angle β to one another and are oriented in the longitudinal direction. These leg areas are also referred to below as contact areas, which outlines their function / task, since they are intended to serve as contact surfaces with the frame. One of the contact areas also has a second spring element. The second spring element has a spring tongue which bends at an angle α with respect to the plane of the contact area of the second leg. This spring tongue could be realized by a piece of angled sheet metal that is point-welded flat onto the contact area. Alternatively, a rectangular area can be defined in the contact area and then the material along three sides cut in a line. Over the remaining fourth side, the material is folded over by the angle α, so that the spring tongue is formed from the material of the contact surface.

In the assembled state, the spring tongue of the second spring element engages in a recess or groove in the basic profile and thereby fixes the basic profile in its desired position on the frame.

1. a) Bereitstellen eines profilierten Rahmens
2. b) Anbringen von Halteklammern am Rahmen
3. c) Befestigen eines Grundprofils auf dem Rahmen durch Aufschieben des Grundprofils auf den Rahmen und Verrasten mit den Halteklammern ohne Verwendung von invasiven mechanischen Befestigungsmitteln wie Schrauben, Nägel oder Heftklammern in allen diesen Montageschritten.

A suitable method for installing a window or door profile system can be described with the following steps:

1. a) Providing a profiled frame
2. b) Attaching retaining clips to the frame
3. c) Attaching a base profile to the frame by sliding the base profile onto the frame and locking it with the retaining clips without the use of invasive mechanical fasteners such as screws, nails or staples in all of these assembly steps.

Assembly step (b) includes, in particular, pushing a retaining clip onto a profile rib provided for this purpose on the frame, then aligning at least two surface areas in parallel with corresponding surfaces or contact areas of the frame. The retaining clip is then anchored to the frame by the spring action of the first spring element, e.g. by pressing the retaining clip until the surface areas and contact areas come into contact.

Furthermore, assembly step (c) can include sliding the basic profile onto the frame in such a way that certain contact surfaces of the basic profile are aligned parallel to outer surfaces of the frame and thus an inner surface of the basic profile comes to rest over the second spring element. In a further step, the spring tongues of the retaining clips snap into a groove in the base profile.

Materials for frames and windows or door leaves, basic profile are known from the prior art, including plastic (especially PVC), aluminum. The material of the retaining clip is preferably sheet metal, but could also consist of plastic.

In a profile system as described above, the dimensions of the retaining clip would be selected to match the requirement profile in order to apply the spring effects on the one hand and the retaining forces on the other. The length of the legs depends on the profile of the frame and the basic profile.

The angles α, β, δ are in the embodiment shown preferably selected as follows: kink angle δ between the first and second leg section between 10 ° and 45 °; Angle α between 10 ° and 60 °; Angle β between 70 ° and 90 °.

• Figure 2 Figure 3 is a top perspective view of a retainer clip
• Figure 3 shows a detailed sectional view through a retaining clip according to the invention
• Figure 4 shows a frame profile with an inserted retaining clip.

Figure 1 shows a profile system in a built-in situation. A frame 16 is provided with various attachments, including a window sill 15, which in connection with the invention is only shown for the sake of completeness in order to illustrate the effect of the weather bar 14. In the picture, the weather side is on the left; the basic profile 10 covers part of the front / top side of the frame 16. The detailed design of the basic profile 10, which can be made of plastic or aluminum as an extruded or extruded longitudinal profile, on the one hand, allows anchoring itself via slots, folds and profile ribs ( n) 17 in / on the frame 16. On the other hand, the base profile 10 can thereby provide mounting positions, eg for a seal 25 or via the fastening position 12 shown here for the weather bar 14. The retaining clip 18 is shown in FIG Figure 1 covered by the basic profile 10. An advantage of the invention is therefore that the functionality is separated. The retaining clip 18 can be designed as a small-format stamped and bent part, which can be functionally optimally designed for the retaining effect between the base profile 10 and the frame 10. Profile 10 and especially frame 18 can be simplified, which in turn helps reduce tool costs.

The structure of a bracket 18 can best be seen with a common look at the Figures 2 and 3 understand. It is divided essentially into a U-shaped bracket with a base 40 and a first (41) and a second (42) leg bent in the longitudinal direction. The longitudinal extent or longitudinal direction is marked with LA for longitudinal axis.

The first leg 41 has a kink fold running in the longitudinal direction with a kink angle δ, which divides the leg into a first leg section 45 and a second leg section 46. The kink line in Figures 2 and 3 is denoted by 51, also extends in the longitudinal direction LA. Figure 3 shows that the interior angle γ between the base 40 and the first leg section 45 is less than 90 °. In the present case, the kink angle δ is defined as the outer angle, as in Figure 3 illustrated. As a result of this design, the first leg forms a spring element 20. The kink line 51 rests on the profile 17 in the assembled state because, due to γ <90 °, the first leg together with the second leg exerts a clamping effect on the profile 16, more precisely on the profile rib 17 .

The second leg 42 comprises two contact areas 43, 44, which are arranged at an angle to one another and oriented in the longitudinal direction LA. The term contact area is intended to express that the assigned surface areas in the installed state are in contact with the frame 16, in particular on surface areas of the profile rib 17 Figure 3 the kink angle between the two contact areas 43 and 44 is denoted by β and is approximately 90 °. A second spring element 22, which in the preferred case is designed as a spring tongue 23, is worked out from the contact area 44. This can be formed from the contact area 44, for example, by attaching a dividing line and bending the surface piece (spring tongue 23) created thereby.

Figure 4 shows the situation of Figure 1 in greater detail with the omission of the add-on parts base profile 10, weatherstrip 14 and window sill 15. The retaining clip 18 is shown in the assembled state on the frame 16. The relative alignment of retaining clip 18 and profile frame 16 takes place in the present exemplary embodiment using a profile rib 17 provided on frame 16 on which the retaining clip is seated. In the example shown, this rib has three outwardly pointing contact surfaces 47, 48, 49, 50. The areas 47, 48 serve as the contact surface (s) for the second leg, the contact area 50 for the first leg 41. The above-described clamp effect caused by the first spring element 20 can be seen.

The frame 16 can also have further profile elements which can serve as support surfaces or holding elements for the basic profile. These are in Figure 4 Shown as profiled outer surfaces with the reference symbols 37 to 39.

In Figure 5 becomes the basic profile as out Figure 1 known, shown in detail without the frame 16 and the retaining clip 18. The weatherstrip 14 is only partially indicated. The contact surfaces 34 and 35 correspond, in the present embodiment, mounted with the Surfaces 37 and 38. The outer surface 39 of the frame 16 serves as a stop for the contact surface 36 of the basic profile. In the basic profile 10, an inner area 33 is provided which has a groove 32. This is intended to accommodate the spring tongue 23 in the installed state. Starting from a pre-assembled retaining clip 18 as in Figure 4 shown, the basic profile 10 would be pushed from the left. The spring tongue 23 is pressed down by the spring 52 and, when the base profile 10 reaches the stop position on the frame 16, snaps into the groove 32. As a result, the retaining clip 18 fixes the relative position of the base profile and frame. Nevertheless, this fastening is reversible because, as shown in the exemplary embodiment shown, the first leg 41 is not covered by the basic profile. Using a suitable tool, the retaining clip can be released from the profile rib 17 and both the frame 16 and the base profile 10 can be separated from one another without being damaged.

Figure 6 additionally shows the entire installation situation of a frame with a window or door leaf. The lower part of Figure 6 is similar Figure 1 and shows a base profile 10 attached to the frame 16, held by a retaining clip 18 (no longer visible). A weatherstrip 14 and a window sill 15 are indicated on the weather side Figure 1 The seal 25 shown is shown here in cooperation with the window sash 19. This seal is designed so that on the one hand it can be connected to the basic profile and on the other hand it bridges the profile rib 17 with the retaining clip 18.

The features of the invention disclosed in the above description and in the drawings can be essential for the implementation of the invention both individually and in any arbitrary, but technically sensible or advantageous combination. A non-explicit representation of a combination of features does not mean that such a combination is not useful or not possible. The invention is defined by the appended claims.
