Abstract

The invention relates to a strip for doors, windows or similar for joining, in a hinged manner, a wing of a door, a window or similar to a frame about the hinge axis (S). Said strip comprises one pair of external hinged parts (1, 1') and an internal hinged part (2) which is arranged between the external hinged parts and which is used to fix, to the frame or wing, two ball bearings (3, 31) that are respectively arranged between the internal hinged part (2) and the external hinged parts (1, 1') and respectively mounted in the step bearings (6, 7), said ball bearings defining the hinge axis (S) in order to provide a pivotable bearing of the inner hinge part (2) in relation to the external hinge parts (1, 1'). At least one of the external hinge parts (1, 1') has an essentially cylindrical bore (4) that extends in the direction of the hinge axis (S) and has inner threads, in which an insert (5) is introduced and which is embodied as a step bearing (6). Said insert (5) comprises an external thread (51) that cooperates with the internal thread (41) in order to release the ball bearings (3) from at least one corresponding step bearing (6, 7) by rotating the insert (5) in the direction of release and when the insert (5) in is the released position (5), the internal hinge part (2) is separated from the external hinge parts (1, 1').

Description

Tape for windows, doors or the like

The invention relates to a boltless, three-piece tape for doors, windows or the like for hingedly connecting a wing of the door, the window or the like to a hinge axis on a frame and thus serve the pivotal attachment of an opening selectively closing wing to the opening limiting components - usually a frame.

Three-piece belts typically comprise three superimposed hinge parts: a pair of hinge hinge outer parts and a hinge part disposed therebetween, which is pivotally mounted about a hinge axis through the hinge parts. It is known to provide a hinge pin for rotatably supporting the inner hinge part. As an alternative to the hinge pin and to obtain a particularly low-friction mounting of the hinge part, it has already been proposed to replace the bolt with balls. Such solutions are known for example from CH 649 123 A5 and DE 103 61 548 A1. These solutions have the disadvantage that the separation of the inner hinge part from the outer hinge parts is very complicated, since a bolt extending between the hinge parts is still present.

To improve this problem, EP 0187337 A2 proposes to arrange two balls in the transition of the hinge parts, ie between the hinge parts, and to provide the bearing cups of the inner hinge part with an adjustable expansion element in order to feed the balls into the associated pans of the outer hinge parts Press or withdraw the balls from the pans of the outer hinge parts to release the inner hinge part. This structure is comparatively complicated and expensive to manufacture. In addition, it is not suitable for relatively heavy doors. It has also been shown that the mechanism is particularly susceptible to failure and fails at the slightest deformation or wear. In addition, the mechanism has the disadvantage that the two balls are withdrawn almost suddenly together and that the inner hinge part abruptly loses its storage on the outer hinge parts, and it thus leads to an uncontrolled falling out of the wing from his Hinge can come, whereby the disassembly of the wing is unnecessarily difficult from its frame.

The invention is therefore based on the object to provide a comparatively simple, stable band with ball and socket storage, the decomposition is facilitated in comparison

This object is achieved by the reproduced in claim 1 band. Advantageous embodiments are the subject of the dependent claims.

The band according to the invention is used for doors, windows or the like for hingedly connecting a wing of the door, the window or the like to a hinge axis on a frame. The tape of the invention can be used in doors and windows of any kind. These are, for example, those in which the frame and / or the wing made of plastic or metal or aluminum hollow profiles in single or multi-chamber design or made of wood. The band according to the invention comprises a pair of outer hinge parts and an inner hinge part for attachment to the frame or wing, wherein the inner hinge part is arranged between the outer hinge parts. Because of the three hinge parts, such a band is usually referred to as a three-piece band. The band has two, each arranged between the hinge parts and each mounted in bearing cups balls. The balls define in cooperation with the bearing pans the hinge axis about which the inner hinge part is pivotable relative to the outer hinge parts or vice versa. At least one of the outer hinge parts has a substantially bore in the hinge axis direction extending cylindrical bore with female threaded portion. Into the bore an insert designed as a bearing socket is inserted. The insert according to the invention has a cooperating with the internal thread external thread to solve by turning the insert in a release direction ball and bearing cup from each other and thus in a release position of the insert to release the ball and to effect a separation of the inner hinge part of the outer hinge parts , In reverse rotation of the insert, the bearing cup is brought back into engagement with the ball. To rotate the insert this is provided for example with a projecting out of the bore section for attaching a wrench. As a result of the embodiment according to the invention, in comparison to the prior art, a simple construction for mounting and for mounting and dismounting the inner hinge part on or from the outer hinge parts is effected. Since the adjustment of the bearing shell in the outer hinge part is only threaded, the construction is susceptible to interference and heavy duty. This susceptibility to interference is based not least on the fact that no fault-prone lever mechanism with comparatively many, against each other moving components is provided. Due to the fact that the inner hinge part has no components for releasing it from the outer hinge parts, its stability remains unimpaired by such components and measures. The inner hinge part can be designed very simply. Due to the inventive design of the insert, the release of the ball takes place gradually and can be "dosed" so that the separation of the inner hinge part is not surprising, whereby the disassembly of the wing is out of the frame particularly safe to perform.

Characterized in that the inserts are arranged with external threads in internal threads of the hinge part, the balls can be displaced by rotational actuation of the inserts in the direction of the hinge axis. It is thereby possible to adjust the hinge part mounted between the balls backlash and adjust to achieve, for example, an equal gap between the hinge parts. It is also possible, a height adjustment of the mounted hinge part - and thus the wing - make when different gaps are accepted.

Preferably, the insert and the ball are joined to form an assembly, i. H. connected so that the ball is captive in the insert. The assembly of the wing hinge part in the frame hinge part is thereby substantially facilitated.

In an advantageous embodiment of the embodiment according to the invention, the bore is continuous and the insert is configured with an engagement such that a tool can be placed over the outer end of the bore in order to effect a twisting of the insert. This makes the band very compact. Furthermore, so the presence of the insert and its adjustment for safety reasons can be easily hidden under a cover. To attach the tool, for example, a hexagon socket (Allen ^® ) or six-round (Torx ^® ) is provided. It may also be a proprietary procedure for applying a tool to counteract the risk of improper adjustment.

In a further advantageous embodiment, the bearing cups of the inner hinge part are formed integrally with the inner hinge part. As a result, the hinge according to the invention can be produced particularly inexpensively.

In a further advantageous embodiment, a bearing socket has a recess in the socket rim surrounding the ball for deflecting the ball out of the socket in a partial release position of the insert. For example, a bearing cup of the inner hinge part is provided with a recess. It is thereby achieved that in a partial release position of the insert, i. for incomplete separation of the ball from the pan, the ball deflected only in a defined position of the inner hinge part with respect to the outer hinge parts and thus the wing can be unhooked from the frame. This has the advantage that in the disassembly of the wing from the frame and after the first rotation of the insert in the partial release position, the deflection of the relevant ball is limited from the bearing cup to a predetermined position of the wing with respect to the frame. The inner hinge part can not surprisingly slip out of the outer hinge parts, and thus the wing can not accidentally fall out of the frame. This significantly increases the safety of dismantling appropriately equipped windows and doors. Also, the mounting ability of the wing is much easier because the wing can be hung in the predetermined position and pre-assembled by subsequent pivoting, whereupon in the pivoted position, the fixation and adjustment by tightening the insert.

In a further advantageous modification of the embodiment described above, the rotation of the insert in the release direction is limited to the partial release position, for example by a stop. This will prevent the insert from being inadvertently twisted to a position where the inner hinge member is removable from the outer hinge members regardless of its position. This increases the safety of dismantling appropriately equipped windows and doors.

In a further advantageous embodiment, a locking means for locking the insert in the associated hinge part is provided. This prevents inadvertent release of the insert.

In a further advantageous embodiment, the locking means is arranged so that when mounting the hinge parts on wings or frame, the locking means is covered when the wing rests against the frame. As a result, it is advantageously prevented under safety aspects that in this position of the wing an improper turning of the insert is made.

In a further advantageous embodiment, the locking means is a threaded pin screwed into a bore of the associated hinge part and an associated groove in the insert. This is particularly simple, reliable and inexpensive locking the invention achieved.

In a further advantageous embodiment, in addition to the or the outer, also the inner hinge part at least one bore and the associated bearing cups are formed as inserts for the bore. As a result, worn bearing pans can advantageously be easily replaced.

In a further advantageous embodiment, at least one insert is provided, which has a bearing socket arranged eccentrically to the bore. This ensures that the hinge axis can be adjusted by means of the adjustment of the arrangement of the eccentric bearing cup. Preferably, such inserts are provided in the inner hinge. These inserts in the inner hinge are provided in one embodiment not with external thread but pluggable, with a groove-notch connection is designed so that on the one hand a rotationally fixed connection is achieved but on the other hand allows the connection a plurality of mutually rotated positions of the insert. Further features, details and advantages of the invention will become apparent from the claims and the following drawing, in which embodiments of bands according to the invention are illustrated, without limiting the invention thereto.

The band according to the invention shown in FIG. 1 comprises three hinge parts, namely two outer hinge parts 1, 1 'and an inner hinge part 2 arranged therebetween. The inner hinge part 2 is pivotably mounted relative to the outer hinge parts 1, 1' by means of ball and socket bearings in that the balls 3, 3 "define the hinge axis S. On the side of the inner hinge part, bearing pans 7 are integrated into the sleeve of the inner hinge part 2 at the top and bottom, and inserts 5 are provided at the top and bottom sides of the outer hinge parts 1, 1 ' , which are respectively inserted into the bore 4 of the associated hinge part 1 and which have a bearing cup 6 for receiving the respective ball 3.

Each insert 5 is provided with an external thread 5 ', which engages in an internal thread 4' of the bore 4, whereby the insert is rotatable and at the same time up or down in hinge axis S adjustable. If one of the inserts 5 moves in the direction of the hinge axis S outwards, ie away from the hinge part 2, the contact between the ball 3 and the associated bearing cups 7 is established. lifted until a release position is reached, in which the hinge part 2 from the stored position between the two outer hinge parts 1, 1 'can be deflected, for example, a not shown wing, which is connected to the hinge part 2, from a frame, not shown to separate, which is connected to the hinge parts 1, 1 '. In order to facilitate the rotation of the respective insert 5, this is provided with an over the outer (upper) end of the bore 4 accessible hexagon socket engagement 8 to which a corresponding tool can be attached.

To secure the inserts in the position in which the inner hinge part 2 is pivotally supported by the balls 3, 3 ¹ , a threaded pin 9 is provided in each case, which is screwed into a bore with internal thread in the relevant hinge part, in a groove of the respective Insert 5 engage and so secure the insert 5 against adjustment.

FIG. 2 is an exploded perspective view of the embodiment shown in FIG. 1, and therefore only supplementary aspects will be discussed below. From FIG. 2 it can be seen that the hinge parts 1, 1 'are connected to one another via a fastening part 10, which is intended to rest against a frame (not shown). The hinge part 2 also has a fastening part 15, which in turn is intended to abut against a wing, not shown. In the hinge part 2, a bearing cup 7 is integrated, wherein the bearing cup 7 has a recess 11 in the surrounding the ball socket edge for the deflection of the ball 3 from the bearing cup 7 in a partial release position of the insert 5. This ensures that in a partial release position of the insert 5, i. in the case of incomplete separation of the ball 3 from the bearing cup 7, the ball 3 is deflected only in a position defined by the position of the recess 11 position of the inner hinge part 2 with respect to the outer hinge parts 1, 1 'and thus the wing can be unhooked from the frame.

Fig. 3 is a sectional view of another embodiment of the tape according to the invention. The components, which are provided with identical reference numerals as in the embodiment of Fig. 1, correspond in function and shape. This embodiment differs from the embodiment shown in FIG. form that the respective bearing cup 17 is not integrated into the inner hinge part 2 '. Rather, these are special inserts 16, 18 which are inserted into a through bore 12 of the hinge part 2 "and the respective bearing cup 17 is arranged eccentrically to the bore 12. As a result, the central axis Z of the bore 12 extends through the balls 3 By adjusting the bearing inserts 16, 18 with eccentric bearing cups, the pivoting movement of the hinge part 2 'and thus of the blade and in particular its orientation with respect to the frame can be adjusted. 4, which is an exploded perspective view of the embodiment known from Fig. 3. The inserts 16, 18 are each provided with vertical grooves 13 in which notches 14 are provided in the bore of the inner hinge part 2 ' a non-rotatable fit is achieved between the respective insert 16, 18 and the bore 13.
