Description

The invention relates to a hinge system for hinged joint connection of a wing with a frame of the preamble of claim 1 corresponding type (see, eg EP-A-1022425 ). Such a belt system is known as a three-piece "Hahn Rollenband". It comprises a wing hinge flap which has a hinge part and a fastening part connected in a materially connected manner to the hinge part. The fastening part protrudes into a profile gap formed between the frame and the wing and is fastened to the frame-facing wall of the wing. The hinge part of this wing hinge flap is located between two spaced-apart hinge parts of a frame hinge flap, wherein the hinge axis is defined by a hinge pin passing through the hinge parts of the wing and the Rahmenbandlappens. The hinge parts of the wing hinge flap are materially connected to a fastening part, which in turn protrudes into the gap formed between the wing and the frame and is fastened to the wing-facing side of the frame.

The distance between the two hinge parts of the frame hinge part is determined by the fact that the fastening part is formed in plan C-shaped, wherein the two free ends of the legs of the C are each connected cohesively with a hinge part.

Although such bands have proven particularly for mounting to frame or wings, the hollow profiles include, since the attachment points are not accessible with the wing closed and thus the wing is particularly well protected against unauthorized disassembly, is disadvantageous, however, that in hollow sections regularly on the side facing the opposite frame or the wing side of the profile provided Dämmschichtbildner, in the case of strong heating For example, drastically increased by a fire volume and thus completely seals the frame opening together with the wing, is interrupted in the region of the band over a longer distance. As a result, there is a risk that just this route is not sealed in case of fire.

The invention is therefore an object of the invention to provide a tape system of the generic type, in which the routes in which no Dämmschichtbildner can be applied to the frame or the wing on the facing sides, is reduced.

This object is achieved by the reproduced in claim 1 tape system.

The band system is characterized in that each band flap part of the at least two hinge parts having band tab comprises a separate fastening part. In the band system according to the invention, the hinge flap, which has at least two hinge flap parts - usually the frame hinge part - no "C" -shaped fastening part, but missing the two legs of the "C" connecting web. By this measure, there is space between the mounting parts for attaching an intumescent on the side of the frame or the wing. To ensure that the gap between the two hinge tab parts is adapted to the length of the hinge part of the other hinge tab so that it can be inserted in the gap and a hinge pin defined hinge pin can be inserted into the hinge parts, an insert is provided whose dimensions to those of the intermediate space are adjusted. This insert includes both the intumescent and force transfer means for transferring forces from one attachment to the other attachment in a direction parallel to the hinge axis. These force transmission means thus define the distance of the fastening parts and thus the hinge parts of the hinge plate parts to each other.

If the band tabs having at least two band tab parts-as is usual in most cases-are mounted in a position on the frame in such a way that the hinge axis runs vertically, it is ensured in the band system according to the invention that a vertical adjustment of the lower band flap part is for the purpose of adjustment the upper and lower clearances of the sash in the frame are readily transmitted to the upper hinge member so that vertical adjustment can be made in the same simple manner as in a conventional three-piece reel hinge.

These adjustment means can be designed as separate components that can optionally be mounted on the frame or the wing, which preferably act on the lower of the hinge-plate parts in a direction parallel to the hinge axis.

In a first preferred embodiment, the power transmission means comprise at least one tube whose length is adapted to the desired gap between the at least two hinge plate parts.

A compact insert comprising the intumescent agent and the force transmission means, which is particularly easy to handle, is achieved when the at least one tube is attached to the intumescent agent.

This can preferably take place in that the tube is longitudinally slotted and provided on the insulating layer forming a projection which engages in the assembled state in the longitudinal slot of the tube. In other words, the slotted tube can be slid onto the protrusion either longitudinally or transversely thereto. The slot width and the thickness of the projection are preferably matched to one another such that the tube cooperates with the projection in the manner of a clamping seat.

In the event that large forces are to be transmitted by means of the power transmission means, it is particularly preferred if the latter are designed such that they at least substantially cover a broad side of the intumescent. By this measure, an at least linear, if not planar introduction of the transmission of forces from one to the other hinge plate part is ensured.

The power transmission means may comprise at least two pipe sections extending parallel to each other, which preferably together by means of a perforated plate are connected. The use of a perforated plate guarantees that the intumescent of the insert can expand in the event of heating almost undisturbed.

Another way of attaching the power transmission means to the insulating layer is to provide self-tapping projections on the power transmission means which can be pressed into the insulating layer former and ultimately form a frictional connection.

The intumescent agent preferably comprises a plate-shaped component. This can be glued, for example, on the space provided for this purpose. However, if this surface has a groove with two undercuts, also called "C" groove, as is the case, for example, with hollow profiles currently used frequently to form a frame, the plate-shaped component may be from an open end side or through a recess provided for this purpose be inserted into the profile groove.

However, the assembly is particularly simplified in that - as particularly preferred - the plate-shaped component is divided into two in a direction extending approximately in the direction of the hinge axis line. It can then be inserted from the front of the two parts in the groove and then laterally displaced so far until the opposite edges engage in the undercuts.

In order to be able to fix the two halves in this end position to each other, the force transmission means is preferably formed so that it extends over both halves and non-positively or positively cooperates with these.

In the drawing, for reasons of clarity, only a section of a frame profile is shown, on which a two-part frame hinge flap of the band system 100 according to the invention is mounted. The not shown in the drawing, other parts of the hinge system such as wing hinge part and the hinge axis S defining hinge pin are not shown. They are designed in the manner known from the prior art.

The in Fig. 1 shown frame hinge tabs 1 comprises two hinge parts 2, 3, which are fixed in a manner known in the art in a "C" groove 4 of a frame profile 5. The hinge flap parts 2, 3 comprise hinge parts 6, 7, to each of which a fastening part 8, 9 is integrally formed. The positioning of the fastening parts takes place with the aid of clamping screws 10, which in the drawing are not recognizable, pull into the undercuts 11, 12 engaging clamping pieces against the back of the respective fastening part. Between the mutually facing sides 13, 14 of the fastening parts 8, 9, a gap 15 is formed, in which an insert 16 is provided.

This insert 16 comprises an approximately plate-shaped Dämmschichtbildner 17, which consists of a material which expands greatly under the action of heat, so as to exist in a fire between the frame and the wing To close gap as completely as possible. This insert is located in the C-shaped groove. The assembly takes place for example by insertion into the groove 4 according to the drawing from above, before the upper hinge plate part 3 is mounted.

To adjust the position of the frame hinge in the direction of the hinge axis, i. can be displaced in the vertical direction in order to adapt the upper and lower gap between wing and frame, an adjustment device 18 is provided which can be selectively attached to the profile and then acts on the lower side 8 'of the fastening part 8. Thus, a simultaneous and equal adjustment of the two hinge parts 2, 3 is ensured, the insert 16 in addition to the intumescent 17 a force transmission means 19, which is formed in the illustrated embodiment of a slotted tube 20. The tube 20 and the intumescent 17 are bonded together to form a compact insert since the intumescent has a projection 23 whose position and dimensions are adapted to the location and dimensions of the slot in the tube to form a press fit.

Will now - as in particular Fig. 1a ) - the lower hinge plate part 2 is displaced parallel to the hinge axis S by means of the adjusting device 18, then the upper hinge flap part 3 follows this displacement, provided that its clamping screws 10 are loosened.

It is understood that above and below the frame hinge flap 1 also strips 21, 22 are inserted from the intumescent in the groove 4.

Hereinafter, the further embodiments with reference to the Fig. 2a) to 2c ) to 4a) to 4c) are explained. To avoid repetition, only the differences from the above embodiment will be discussed. Otherwise, reference is made to the above description.
