Abstract

The hinge (100) has a frame part (2) fixable on the frame and a casement part (1) fixable on the casement. A hinge bolt is fixed rotationally secured in one of the hinge parts (1) and in the area engaging in the other hinge part (2) has an axial stop face. The other hinge part (2) has an axial counter stop face and the stop and counter stop faces are arranged so that in one position of the hinge parts which corresponds to the closed casement they lock the hinge bolt in the second hinge part in the direction of the hinge axis (S). The hinge bolt has at the end of an area projecting into the other hinge part an axial projection of smaller diameter on which a radially protruding projection is formed which creates the first stop face.

Description

The invention relates to a band for doors, windows or the like, comprising a frame hinge part which can be fastened to a frame, with a wing hinge part which can be fastened to a wing and with a hinge pin which engages in the frame and wing hinge parts and which pivotably connects the hinge parts about a hinge axis.

Such hinges are known in various embodiments. In order to facilitate the assembly of the wing, the hinge pin is usually in one of the band parts, often preassembled the frame hinge part. After attachment of the frame hinge part and the leaf hinge part at the designated locations of the frame and the wing then the wing can be suspended by sliding the frame hinge part with the space provided for this longitudinal recess on the hinge pin and thus mounted in a simple manner. The wing can then be posted in any angular position to the frame, in which the frame does not block a sufficient longitudinal displacement of the wing in the direction of the hinge axis.

Such bands always provide adequate protection against break-in by unhooking the wing in the closed state, when seen between the wing and the frame in the direction of the hinge axis existing inside width smaller than that in the other band part in which the hinge pin displaces in the axial direction can be is.

Modern wing and frame constructions with so-called "deck-up", i. in those in which the wing rests from the outside on the front surface of the frame, a greater clearance between the wing and frame is often required, for example, to provide greater adjustment options and thus the facing edges of the wing and frame even in the closed state of the wing are more accessible.

The invention has for its object to further develop a generic tape to the effect that the hinge pin can not be expelled with the wing closed. It is a further object of the invention to design the measures required for this purpose so that the assembly and disassembly of the wing in the open state is not complicated.

From the DE 92 07 140 U1 a band is known in which a band member directly has an inwardly projecting nose which engages in an annular groove of a flattened band pin. The FR-A-2 836 175 shows a band in which a projection is arranged directly on a band part, which engages in a groove of a flattened band pin. Also from the FR-A-2 769 940 a band is known in which a band member directly has a projection which engages in a groove of a band pin with a flattening.

This object is achieved by the reproduced in claim 1 invention.

Characterized in that the hinge pin is arranged rotationally fixed in one of the band parts, it performs during pivoting of the wing a pivot angle corresponding to the rotation about the hinge axis relative to the other band part. Since it comprises an axial abutment surface formed by at least one radially projecting extension (8) in the region engaging in the other band part, which displaces its position on a circle concentric with the hinge axis when the blade moves, the other hinge part comprises a radially at least one inwardly directed counter-extension (10) formed axial counter-abutment surface which is arranged relative to the stop surface such that it is in a position of the band parts to each other, which corresponds to its position with the wing closed, seen in the direction of the hinge axis in register with the stop surface.

It can be determined by the arrangement and / or dimensioning of the stop and counter stop surfaces of the opening area in which a hanging of the wing should be possible.

The hanging of the wing prepares in the band according to the invention no greater difficulties than in a conventional band, since the wing needs to be hung only in the open position by inserting the hinge pin in the longitudinal recess of the other hinge part.

In a particularly preferred constructive variant, the stop surface is formed by a radially projecting extension, which is provided on an axial extension of smaller diameter, which extends from the front end of the hinge pin.

The other hinge part then has to form the counter stop surface on a radially inwardly directed counter-extension, which is provided either on a provided in the longitudinal view of the hinge part bearing bush or to a provided in the longitudinal recess in the direction of the hinge axis fixed securing ring. The band part can then be produced inexpensively by separating a section of an extruded profile. Only the bearing bush must be made of a material which is suitable for rotating the belt bolt over the life of the belt and receiving it substantially free of play.

The locking forces which the tape according to the invention is able to absorb in the closed state of the blade are then particularly high if two radially projecting extensions and two radially projecting counter-projections are provided on the hinge pin. Basically, the locking forces are greater, the greater the number of successive extensions and counter processes and the associated surfaces into which locking forces are introduced are. However, it has been found that the provision of two opposing projections is a good compromise between the height of the recordable locking forces and the restriction of the angular range, in that even an opened wing can not be unhooked or suspended.

In a particularly preferred embodiment, one band part is the wing band part and the other band part is the frame band part, in other words: the counterpart projections are provided on the frame band part.

The band indicated as 100 in the drawing as a whole comprises a wing hinge part 1 and a frame hinge part 2.

Wing hinge part and frame hinge part 1, 2 are pivotally connected to each other by means of a hinge pin 3 about a hinge axis S. For this purpose, the hinge pin 3 protrudes with its according to the drawing, the upper area in a provided in the leaf hinge part, not visible in the drawing longitudinal recess and is rotatably arranged in this.

The lower region of the hinge pin 3 according to the drawing projects into a longitudinal recess 4 of the frame hinge part 2. He is - like Fig. 7 can be removed - surrounded by a bearing bush 5, which consists of a material or a combination of materials, which ensures a substantially backlash-free seat of the rotating in the bearing bush 5 hinge pin 3 for the life of the band.

At his according to Fig. 7 lower, engaging in the frame hinge part 2, front end 6, the hinge pin 3 has an axial extension 7, whose diameter is smaller than the diameter of the hinge pin 3. At the free end of the axial extension 7 two radially projecting extensions 8 are arranged offset by an angle of 180 °.

Below the bearing bushing 5, a retaining ring 9 is arranged, whose inner and outer diameter of the bearing bush 5 approximately correspond.

As in particular from Fig. 3 shows, the retaining ring 9 offset by 180 ° arranged, inwardly directed, radially projecting counter-processes. The distance between the two mutually facing edges of the Gegenfortsätze is slightly larger than the outer diameter of the axial extension. 7

The extensions 8 form axial abutment surfaces 11 of the hinge pin 3, which cooperate with the Gegenanschlagsflächen formed by the Gegenfortsätzen 10 of the frame hinge part 2 when the hinge pin is in a rotational position in which the extensions 8 and counter-processes 10 viewed in the direction of the hinge axis S at least partially cover.

The securing ring 9 can be inserted into the longitudinal recess 4 by means of a part of the longitudinal recess 4 of the frame hinge part 2 which is provided below the bearing bush 5 and which is provided with an internal thread. For the purpose of fixing the locking ring 9 in a pressed and rotationally fixed to the lower edge of the bearing bush 5 position is a threaded bushing 13, which is screwed into the internal thread 14 of the lower part 15 of the longitudinal recess 4.

As 4 to 6 can be removed, there is the circlip 9 in an angular position in which the stop and counterstops surfaces 11, 12 completely cover when the wing is closed. Now, the wing is opened by about 45 ° and the wing hinge part 1 relative to the frame hinge part 2 in the Fig. 1 to Fig. 3 brought removable position, the stop surfaces 11 are no longer covered by the counter-stop surfaces 12 and the hinge pin 3 can in the direction of the hinge axis S according to Fig. 1 be pulled up from the bushing 5.
