Description

[0001] The invention relates to a multi-leaf door of a folding sliding door, according to the preamble of claim 1.

[0002] Such doors have at least two adjacent leaves that can be moved relative to each other for opening or closing, one leaf being a fixed leaf and the other a moving leaf, with a lock operated by handles which, in the closed position, engages with a locking tongue in a locking opening in the faceplate area of ​​the opposite composite profile.

[0003] To form a fold in the area of ​​the two adjacent composite profiles, profiles are currently screwed onto the chamber profiles forming the respective composite profiles, which, however, involves considerable manufacturing and assembly effort.

[0004] Moreover, the joints present in this area due to the construction method lead to reduced tightness, which is just as regrettable as the appearance, which is often perceived as disturbing from a design point of view.

[0005] The aforementioned considerable manufacturing and assembly effort required to produce the rebate area of ​​a multi-leaf door according to the state of the art arises primarily from the large number of components required. The completion of the composite profiles is carried out as needed, meaning that the individual components that are joined to form a composite profile cannot be pre-assembled. This applies particularly to machining operations such as sawing to length, notching at the profile ends, creating milled pockets, and drilling holes for fittings or similar components.

[0006] A generic multi-leaf door is disclosed in EP 1 365 097 A2.

[0007] The resulting high manufacturing and assembly costs are diametrically opposed to the constant demands for cost minimization.

[0008] The invention is therefore based on the objective of further developing a multi-leaf door of a folding sliding door of the generic type in such a way that its manufacture and assembly are simplified and more cost-effective.

[0009] This problem is solved by a multi-leaf door with the features of claim 1.

[0010] This design offers a number of advantages over the prior art. These include, first and foremost, the reduction of individual parts required to manufacture the rebate area, and in particular the identical design of the locking profiles with which each composite profile is sealed on the facing sides of the sashes to be opened or closed.

[0011] Each of these composite profiles consists of two opposing chamber profiles, preferably made of light metal, in particular aluminium, which are arranged apart from each other and are connected to each other by spacer webs.

[0012] These spacers are made of dimensionally stable plastic, as is the locking profile, to which a cover strip is attached on the outside.

[0013] According to a further aspect of the invention, the respective locking profile, which is arranged particularly in the faceplate area of ​​the composite profile, is connected to the chamber profiles by a form-fit and / or friction-fit connection, in particular by snapping. Additionally, the locking profile can also be connected to an adjacent spacer by snapping, resulting in a very stable connection.

[0014] To form a rebate area between the adjacent composite profiles, their respective chamber profiles, viewed in the sliding direction of the sash, differ in their cross-sectional dimensions, resulting in an overhang of one chamber profile to the other, specifically on the side facing the other sash or composite profile.

[0015] Preferably, the composite profiles are identical in cross-section, which also contributes to a reduction in costs.

[0016] The design of each composite profile according to the invention leads to significantly improved thermal insulation and increased tightness, especially against driving rain and air permeability.

[0017] Since, unlike the state of the art, no additional profiles need to be screwed on, joints are reduced, resulting in an improved and more appealing appearance to the viewer.

[0018] In the more compact composite profile made possible by the invention, necessary functional elements can be positioned, such as receiving grooves for seals, guides for locking bolts, receptacles for a multi-point locking system or similar.

[0019] The simpler manufacturing and assembly of the new multi-leaf door also results from the fact that pre-drilling or screwing is no longer necessary, as the completed composite profile can be processed in a single operation on a machining center – i.e., cut to length, notches attached to the profile end, and milled pockets and holes for fittings or the like. This also leads to a significant reduction in costs.

[0020] Further advantageous embodiments of the invention are characterized in the dependent claims.

[0021] An embodiment of the invention is described below with reference to the accompanying drawings.

[0022] They show: Figure 1 two composite profiles according to the invention as a detail in a cross-section Figure 2 a cross-section through a lock area of ​​two closed leaves Figure 3 a section of a leaf frame in an exploded view Figure 4a) - 4d) different folding sliding doors in a schematic top view.

[0023] In the Figure 1 Two composite profiles 1 forming a frame part are shown, which are part of a multi-leaf door of a folding sliding door, wherein the leaves can be opened and closed, i.e. the two composite profiles 1 shown are movable relative to each other.

[0024] Each composite profile 1 consists of a first chamber profile 2 and a second chamber profile 3 arranged at a distance from it, which are connected to each other by spacers 4, wherein the chamber profiles 2, 3 are made of a light metal and the spacers 4 are made of a dimensionally stable plastic.

[0025] According to the invention, the opposing composite profiles 1 are closed at least partially on their mutually facing sides by closure profiles 5 which are identical in cross-section and which are preferably also made of plastic and which are connected to the chamber profiles 2, 3 as well as to the facing spacer 4 in a form-fit and / or friction-fit manner, preferably by snapping.

[0026] For this purpose, the respective closure profile 5 has both tongues 6 which are inserted into correspondingly shaped receptacles of the chamber profiles 2, 3, as well as clamps 7 which overlap a projection of the adjacent spacer 4.

[0027] By appropriately configuring the chamber profiles 2, 3 and the closure profile 5, a receiving groove 8 is created in which door seals 9 (Figure 2) are held.

[0028] The spacer 4 facing the locking profile 5, like the locking profile 5 itself, defines a space 17 for accommodating fitting components, for example a locking bolt 12, as shown in the Figure 2 is recognizable, and / or a deadbolt lock.

[0029] This figure shows the arrangement of the composite profiles 1 according to the Figure 1 in the closed position of the leaves with a box lock built into one active leaf, the locking tongue 14 of which projects into a strike plate of the adjacent inactive leaf, the box lock being operable via a handle 11.

[0030] A glass pane 13 is held on each of the sides of the composite profiles 1 facing away from the locking profiles 5, with the lower side of the composite profiles 1 forming a room side when the door is installed.

[0031] It can also be seen that the locking profiles 5 are each covered on their mutually facing sides with a cover strip 10, which is connected to the locking profile 5, for example also by snapping.

[0032] In the Figure 1 and 2 It can further be seen that each first chamber profile 2 is shorter than the opposite second chamber profile 3 when viewed in the direction of movement of the respective wing, so that an overhang results in the direction of the other composite profile 1, thereby forming a rebate.

[0033] The closure profiles 5 are identical in cross-section, as are the composite profiles 1, one of which is mirrored in cross-section about an imaginary horizontal and vertical axis compared to the other composite profile 1.

[0034] In the Figure 3A section of a fixed leaf is shown, with a visible second chamber profile 3 and inserted locking profiles 5, as well as cover strips 10 in the exploded view. The fixed leaf is locked by means of a handle 16. A faceplate 15 with a receiving chamber for the locking tongue 14 is arranged between two locking profiles 5, as are further locking means for a multi-point locking system provided above and below it.

[0035] In the Figure 4 The diagram schematically depicts folding sliding doors with a varying number of panels, each with one active panel to which a handle 11 is attached. The Figure 4a ) a variant with a total of six leaves is shown, whose main leaf and the associated fixed leaf are positioned in the middle, while in the Figure 4b ) four wings are provided with a passage wing and a fixed wing on the right-hand side.

[0036] The Figure 4c) shows a design with a total of eight wings, of which, viewed from one side, the third is designed as a fixed wing and the fourth as a moving wing, while the Figure 4d ) represents a mirror-image arrangement. Reference symbol list
