Description

[0001] The invention relates to an assembly aid for plug-in frames.

[0002] Furthermore, the invention relates to a plug-in frame kit comprising an assembly aid.

[0003] Frames are a component of many doors and windows and form the frame into which door leaves or window sashes are inserted in a building opening.

[0004] Frames are often installed during the construction of a building in the designated structural openings, especially wall openings. For this purpose, one-piece frames, also called wrap-around frames, are usually used. These surround the wall on both sides of the wall opening with a roughly U-shaped profile and are installed during the wall construction.

[0005] Plug-in frames, also known as two-part frames, are particularly suitable for retrofitting because they can be conveniently inserted into existing building openings. These frames are divided into two frame elements, for example, a rebate element and a counter element, which each enclose the building opening on only one outer side and are connected to each other during installation in the building opening.

[0006] Plug-in frames are usually made of metal, particularly steel.

[0007] Surrounding frames for doors have three frame parts, namely the two side parts and the head part, which in the case of plug-in frames are each divided into a rebate element and a counter element, also called a lining element.

[0008] Various manufacturing processes for plug-in frames and plug-in frame kits are known, from which the plug-in frame kits emerge in various degrees of disassembly.

[0009] The present invention relates in particular to plug-in frame kits in which the frame components are pre-assembled in a U-shape. The invention particularly relates to two-part plug-in frame kits in which the side components and the head component of the rebate side and the lining side are already connected to one another, and in which at least some of the frame elements of the rebate side and the lining side are connected to one another. In the case of one-piece production, the latter can be achieved via predetermined breaking points that are separated before assembly, and in the case of other manufacturing processes, via screwing or other detachable connection techniques.

[0010] The free ends of the U-shaped pre-assembled plug-in frames / plug-in frame kits represent a weak point during storage and transport of the plug-in frames / plug-in frame kits, since forces acting on these free ends can, for example, lead to bending of the frame parts or to the breaking of connections between the frame parts.

[0011] Furthermore, when installing the plug-in frames, it is important to maintain the clear width or frame rebate dimensions across the entire height of the frame. In the headboard area, this is already predetermined by the headboard. As the side panels extend toward the free ends, the distance between the side panels is laboriously measured and, if necessary, adjusted.

[0012] It is an object of the invention to provide an assembly aid which at least partially eliminates the aforementioned problems.

[0013] This object is achieved according to the invention by an assembly aid according to claim 1.

[0014] It is a further object of the invention to provide a plug-in frame kit which at least partially eliminates the aforementioned problems.

[0015] This object is achieved according to the invention by a plug-in frame kit according to claim 4.

[0016] Advantageous aspects of the invention are claimed in the dependent claims.

[0017] The features of an assembly aid and a plug-in frame kit disclosed below are part of the invention in all executable combinations.

[0018] The assembly aid according to the invention has an elongated body made of a solid material, preferably of a metal or a hard plastic.

[0019] For example, the assembly aid is designed as a strip with a length that corresponds at least to the frame rebate dimension of the plug-in frame to be installed plus four times the thickness of the material of the rebate parts.

[0020] Preferably, the length of the assembly aid is at least 5 to 10 mm longer than the frame rebate dimension of the plug-in frame to be installed.

[0021] In the body of the assembly aid, two openings, in particular designed as round through-openings, are arranged, the distance between which is selected for fixing the side parts, in particular the lining parts, of the plug-in frame to be assembled during storage and transport of the plug-in frame kit.

[0022] The assembly aid can be screwed to the side parts, especially the lining parts, of the plug-in frame kit through the through openings.

[0023] Additionally, the body of the assembly aid features two parallel slots, the spacing of which is selected for adjusting the frame rebate dimensions during assembly of the rebate parts when the assembly aid is attached to a rebate part with the slots. Thus, taking into account the wall thickness of the rebate parts, the slots are spaced approximately at the same distance as the frame rebate dimensions of the frame to be installed.

[0024] In embodiments of the invention, variants of the assembly aid with several pairs of openings and / or slots are also conceivable, which serve for use with plug-in frames of different clear widths or different frame rebate dimensions.

[0025] To improve the stability of the assembly aid, it is preferably designed as an angle profile with at least two walls connected at an angle.

[0026] Particularly preferably, the openings are arranged on a common wall of the angle profile, and the slots are arranged at least substantially together on the / another wall of the angle profile. This serves to further stabilize the assembly aid.

[0027] The assembly aid according to the invention combines two functions. The first function is achieved by screwing the assembly aid through the openings on the side panels of the frame assembly kit during storage and transport by stabilizing the side panels at a distance equal to the clear width. This significantly reduces the risk of possible damage to the frame assembly kit during storage or transport, for example, due to bending of the side panels.

[0028] At the installation site, the screw connection is loosened and the assembly aid is removed from the side parts of the plug-in frame kit.

[0029] The rebate parts of the insert frame kit are then separated from the lining parts. If the insert frame kit is manufactured as a single piece with respect to the associated rebate and lining parts, the parts are broken off. Otherwise, the transport fastening, for example, the screw connection, is loosened.

[0030] The second function of the assembly aid is achieved by attaching the slots to the rebate parts of the plug-in frame kit during assembly. Here, the assembly aid acts as a spacer element for precisely adjusting the frame rebate dimension of the frame to be installed. For this purpose, the assembly aid can preferably be connected to the opposite rebate parts of the plug-in frame in at least one position. Particularly preferably, the assembly aid can be connected to the rebate parts of the plug-in frame in at least two positions, in particular a first position in the area of the end of the rebate parts facing away from the headboard and a second position at a height of approximately 1 m above the lower end of the plug-in frame.

[0031] A frame assembly kit according to the invention comprises at least two frame parts, namely a rebate part and a lining part, each of which has two side parts and a head part. Furthermore, the frame assembly kit comprises at least one assembly aid according to the invention, which, during transport or storage of the frame assembly kit, is detachably connected to the side parts, in particular to the side parts of the lining part, and fixes them at a distance equal to the clear width of the frame assembly kit.

[0032] For this purpose, the assembly aid is preferably screwed through the openings to the side parts, in particular in the area of the lining parts, in the area of a first connecting element.

[0033] Most preferably, the side parts of the lining parts and the rebate parts of the insert frame kit are offset from one another by an offset V in the transport or storage state, so that, preferably, the rebate parts only begin at a height V from the lower end of the insert frame kit. This creates an assembly area for the assembly aid at the lower end of the insert frame kit, in particular at the lining parts, in which the assembly aid is screwed through its openings to the side parts of the insert frame kit in the region of the first connecting element in the transport or storage state.

[0034] In embodiments of the invention, the offset V is approximately 21.5 mm.

[0035] The rebate parts of the plug-in frame kit each have at least one second connecting element in the area of the side parts, preferably at least two second connecting elements at different heights, for connection to the assembly aid in the area of the slots.

[0036] According to a first embodiment, the second connecting elements are designed as horizontal connecting slots arranged on the opposite folding parts at the same height, starting from the folding-side end of the folding part.

[0037] The connecting slots are preferably dimensioned so that they are at least substantially accommodated in the rebate of the fully assembled door and are completely concealed at the latest by the installation of the rebate seal in the frame.

[0038] In one embodiment of the invention, the connecting slots are approximately 18 mm long and approximately 4 mm wide. The width depends on the thickness of the mounting aid to be used.

[0039] According to a second embodiment, the second connecting elements are designed as hooks on the folding part, which extend out of the folding parts at the fold-side end of the folding parts in the direction of the lining side.

[0040] According to this embodiment, the assembly aid functions as a spacer during assembly and is inserted with the slots onto the folded parts and sits on the hooks.

[0041] The hooks can, for example, be the connecting elements or part of the predetermined breaking points of the still-connected rebate and lining parts in a one-piece plug-in frame. In a fully assembled plug-in frame, the hooks are accommodated in the rebate in embodiments of the invention.

[0042] In principle, the combination of second connecting elements designed as connecting slots with second connecting elements designed as hooks is also possible.

[0043] The following drawings illustrate exemplary embodiments of the invention. They show: Fig. 1: Technical drawings of an embodiment of the assembly aid in four views, Fig. 2: A cross-section of a plug-in frame kit in transport and storage condition, Fig. 3: A section of a perspective view of a plug-in frame kit in transport and storage condition in a first embodiment, Fig. 4: A section of a perspective view of a plug-in frame kit in transport and storage condition in a second embodiment, Fig. 5: A cross-section of a plug-in frame kit with separate rebate and lining parts, Fig. 6: A cross-section of the plug-in frame kit according to the first embodiment during assembly, Fig. 7: A section of a perspective view of the plug-in frame kit according to the first embodiment during assembly, Fig. 8: A cross-section of the plug-in frame kit according to the second embodiment during assembly and Fig. 9: A section of a perspective view of the plug-in frame kit according to the second embodiment during assembly.

The length of the mounting aid (1) is the clear width plus 44 mm. The walls (2, 3) are each 20 mm high. The parallel slots (4) are arranged together essentially in the first wall (2), but also extend slightly onto the second wall (3). The slots (4) are 2 mm wide and are spaced 5.25 mm from the ends of the mounting aid (1) and spaced apart by the frame rebate. The openings (5) are provided in the second wall (3) and have a diameter of 6 mm.

[0045] Fig. Figure 2 shows the plug-in frame kit (10) according to the invention in transport and storage condition. The rebated parts (11) and the lining parts (12) are connected to each other, and the side parts (13) are connected to each other via the assembly aid (1) with the aid of the first connecting elements (14) arranged in the lining parts (12).

[0046] The assembly aid (1) is screwed through the openings (5) with the lining parts (12) of the plug-in frame kit (10) into the first connecting elements (14) designed as holes.

[0047] Fig. Figure 3 shows the plug-in frame kit (10) of a first embodiment in transport and storage condition. The rebate parts (11) are offset V of 21.5 mm relative to the lining parts (12), so that a mounting area (15) for the mounting aid (1) is created at the lower end of the lining parts (12). In this mounting area (15), the mounting aid (1) is screwed to the lining parts (12) of the plug-in frame kit (10). This also applies to the Fig. 4 shows the second embodiment.

[0048] According to the first embodiment, the second connecting elements (16) in the rebate parts (11) of the plug-in frame kit (10) are designed as horizontal connecting slots, which in the present case have a length of 18 mm and a width of 4 mm.

[0049] According to the Fig. In the second embodiment shown in Figure 4, the second connecting elements (16) on the rebate parts (11) of the plug-in frame kit (10) are designed as hooks which extend from the rebate-side end (17) of the rebate parts (11) in the direction of the lining parts (12).

[0050] In Fig. 5 Compared to the transport and storage state of the plug-in frame kit (10), the lining parts (12) are separated from the rebated parts (11). The assembly aid (1) remains screwed to the lining parts (12). Before the assembly shown in the following figures, the assembly aid (1) is detached from the lining parts (12).

[0051] According to the Fig. 6 and Fig. 7, the assembly aid (1) according to the first embodiment of the invention is connected to the rebate parts (11) as a spacer. The second connecting elements (16), designed as connecting slots, in the rebate parts (11) are brought to the same distance as the slots (4) in the assembly aid (1), and the assembly aid (1) is inserted into the connecting slots in this position, so that the rebate parts (11) are held at the rebate width. In the example shown, two assembly aids (1) are used at two different heights to adjust the rebate width, so that compliance with this width is supported across the entire height of the frame.

[0052] In the Fig. 8 and Fig.9, the assembly aid (1) according to the second embodiment of the invention is connected to the rebate parts (11) as a spacer. The rebate parts (11) are brought to the distance of the slots (4), and the assembly aid is placed onto the rebate parts (11) above the second connecting elements (16) designed as hooks. The assembly aid (1) is then placed on the hook. In the example shown, two assembly aids (1) are used at two different heights to adjust the rebate width, thus supporting compliance with this width across the entire height of the frame.
