Description

The invention relates to a band for doors, windows or the like comprising at least one hinge flap, with at least one attachable to a frame or on a wing band attachment portion, at least one recess for receiving a hinge axis defining hinge pin having hinge portion, and at least one band hinge portion and / or the band attachment portion at least partially surrounding cap, which in a final assembly position with an inner side wall - at least on an outer circumferential surface of the hinge portion - preferably full surface - directly or indirectly rests and is clamped to the band by means of a biasing force.

Such straps for doors, windows or the like are known in various embodiments, such a band typically comprises a band attachment portion which may be formed, for example, as a hinge strap or merely as a region for receiving fasteners, and a band hinge portion. The band hinge portion is usually cylindrical in so-called roller bands and usually comprises in particular a body connected to the band attachment portion body having a longitudinally extending recess for receiving the hinge pin and a roller belts for the most round outer contour.

Furthermore, caps are well known. These are generally used for protection, for example against dust or dirt deposits on the usually rotatably mounted hinge pin, as well as for improved optical design of the component to be covered, in this case in particular to the respective band section. For this purpose, the cover usually has a corresponding to the respective band portion shape. The cap may, for example, completely or at least partially cover the band tab, enclose and / or - for example, even for a clamping attachment - embrace. Particularly preferably, the covering cap covers the means for fastening the band to a frame or wing or a recess for making these means available. For this purpose, the cap can usually be pushed with little effort on the component to be covered and / or pressed and thus clamped to this locked. It should be clear that the term "clamping" in particular a fixing of the cap on the hinge strap to form a biasing force or clamping action is to be understood, for example by means of a one, Um- or engaging behind a prestressed first component, such as the cap in or an undercut, depression, recess, recess or contour of a second component, such as the band.

From the DE 299 07 488 U1 For example, a door hinge with a band hinge portion surrounding cap is known. The cap abuts against the outer circumferential surface of the hinge portion and is fixed by a kind of bayonet closure by means of an additionally arranged in the end region of a band cover on the door hinge.

However, the cap is usually a separate and last in the assembly process needed component. Thus, for a door hinge, for example, first the mounting of the bands to the frame and door, then a mounting of the door to the frame, then usually an assembly of accessories such as a Opening handle, and finally an adjustment of the door with respect to the opening frame. In these assembly steps, the cap is - not to hinder the assembly and / or adjustment - usually not arranged on the hinge strap. Depending on the location of the door or window and / or the progress of the construction, it may be necessary to adjust the sash to the frame at a later time, for example due to gradual changes such as thermally induced expansion of an adjacent component or of the component itself - must be repeated. For this purpose, it may be necessary to remove the cover from the component again, which is relatively complicated and expensive in most covers - once they are in their final assembly position.

Another disadvantage is that the cap in a product packaging usually has to be kept separate in a separate compartment, whereby the packaging is relatively expensive. Furthermore, the cap is usually relatively small and unobtrusive, so that it can be quickly overlooked when unpacking the tape from the package and disposed of in the worst case together with the packaging box. In addition, occurs in a removal of the cap from the packaging in practice again and again the problem that the cap due to their - as explained above - until relatively late use for assembly is lost temporarily.

It is therefore an object of the present invention to provide a band with a covering cap which improves at least one of the abovementioned disadvantages.

The invention solves the problem by a band with the features of the main claim. Advantageous embodiments and further developments of the invention are disclosed in the subclaims, the description and the figures.

According to the invention, the cover cap is additionally arranged in a transport position for temporary fixation on the hinge hinge portion parallel to the hinge axis at least partially spaced from the outer circumferential surface of the hinge portion and fixed clamped to the hinge portion by means of a biasing force. As a result, the covering cap can be fixed to the hinge flap immediately after its manufacture and before insertion, together with the hinge flap, into a packaging in a position which can be easily released again from the strip. In particular, the cap can be releasably fixed to the hinge flap again without additional aids. As a result, the packaging costs can be kept relatively low. Furthermore, for assembly - for example, on a construction site - only the removal of a single part from the packaging required, namely the tape together with the fixed at the hinge flap cap. Further, the cap may particularly preferred to remain before, during and after assembly and / or adjustment of the tape on the door, window or the like in the transport position on the hinge flap, so that the likelihood of loss of the cap before, during and after assembly clearly is reduced. In addition, the cap can be loosened or removed at any time in a relatively simple manner if necessary from the hinge flap. After completion of the assembly and / or adjustment, the cover located in the transport position can be pushed or moved to the final assembly position. Overall, this makes a particularly safe, fast, simple and inexpensive installation possible.

Preferably, the cap is formed in a first embodiment of the invention as a longitudinally open, at least semicircular cover sleeve each with a - arranged in particular on the longitudinal extension of the cover - arranged on both sides of a sleeve longitudinal sleeve Endes, wherein on the outer lateral surface of the hinge portion at least one longitudinal recess is formed in which the cover sleeve is in the transport position with at least one Hülsenendbereich engaging a clamping effect into engagement and thereby can be fixed to the tape. For example, one of the sleeve end regions may be disposed in a transition region formed between the band hinge portion and the band attachment portion and the other sleeve end region in the longitudinal recess. As a result, the formation of only one depression in the hinge portion is required for the transport position, so that the band can be constructed particularly inexpensive.

In this embodiment, a second longitudinal depression is additionally preferably formed on the outer circumferential surface, wherein the covering sleeve engages in the transport position with the first sleeve end region in the first longitudinal depression and with the second sleeve end region in the second longitudinal depression. In particular, on the outer lateral surface of the hinge band portion two circumferentially substantially oppositely disposed longitudinal recesses may be formed, in which the cover sleeve in the transport position in each case with a Hülsenendbereich engaging a clamping action is engaged and thereby fixed to the hinge tab. For example, the two longitudinal recesses are arranged circumferentially to one another in an angle range of 160 ° to 180 ° facing the cover sleeve, in particular 170 °. Thereby, the cap can be brought in a particularly simple manner frontally on the hinge portion in the transport position and temporarily fixed by acting on the longitudinal recesses biasing or clamping force in a particularly simple manner on the tape.

In another embodiment of the invention, the cover cap is preferably designed such that it at least partially, preferably completely covers the band attachment portion and the band hinge portion on a side facing away from the frame or the wing. In particular, this embodiment may be so-called Aufschraubbänder in which the band attachment portion is mounted on a visible side of the wing or the frame. Of the cover cap formed as above then the band attachment portion is then at least partially, preferably completely covered, which can be significantly improved, inter alia, the visual appearance of the final mounted band.

Particularly preferred is in particular in a trained as "Aufschraubband" band when a first longitudinal recess and / or on an outer circumferential surface of the band attachment portion, a second longitudinal recess is provided on the outer circumferential surface of the hinge portion. If the cover cap then-as is particularly preferred-has two cover cap regions spaced apart from one another, wherein in the transport position one of the cover cap regions engages with one of the first and second longitudinal depressions to form a clamping effect, then the cap can be preassembled in a captive manner. For final assembly, it is then only necessary, the Cover cap to overcome over the clamping effect from this transport position to transfer to the mounting position, including the in the transport position in one of the first and second longitudinal recess located Abdeckkappenbereich must be shifted out of this.

Preferably, the longitudinal recesses are homogeneously concave. For example, the longitudinal recesses may be formed as a depression, groove or longitudinal groove, in particular rounded longitudinal groove. As a result, only a small amount of force is required to engage and / or remove the cap.

Preferably, in the transport position, the distance between an inner side surface of the cover cap and the outer circumferential surface of the band hinge portion substantially corresponds to a radius of the recess. As a result, the cap is to handle in a particularly simple manner, so that for engaging the cap with the tape, for removing the cap from the tape and / or for moving the cap in the final assembly position, only a relatively small amount of force is required.

Preferably, the cover cap is designed to be flexible so that the cover can be optionally both in the transport position and in the final assembly position in the direction substantially perpendicular or parallel to the hinge axis on the hinge tab, in particular on the hinge hinge portion, pushed and / or clipped. As a result, an assembly of the cap on the band with only a particularly small amount of force is possible. Further, the cap can be moved both in the transport position and in the final assembly position along the belt in the direction parallel to the hinge axis, so that portions of the cover to be covered by the cap band portion can be exposed in a particularly simple manner and made accessible from the outside.

Preferably, the cap is fixed to the hinge tab so that the cap from the transport position can be moved directly into the final assembly position. This allows a particularly simple and quick installation of the cap on the hinge flap. In particular, after completion of the assembly and / or adjustment located in the transport position cap can be pressed or moved by means of a light pressure effort directly into the final assembly position. Here, the term "immediate" is to be understood in particular that to change the position of the cap from the transport position to the final assembly position, a decrease or release of the cap from the hinge flap is not required.

Particularly preferably, the band, in particular the band hinge portion, at least one recess through which means for fastening the band to the frame or on the wing are accessible for the purpose of application, this recess in the final assembly position of the cap completely covered and optionally in the transport position Covered by the cap or freely accessible. In particular, the covering cap can-as described above-preferably be displaced along the hinge flap in the direction parallel to the hinge axis, so that, for example, the area of the recess or recesses can be exposed, and thus an application of a fastening means at a cover cap temporarily fixed to the hinge flap is made possible.

Preferably, the means for fixing the band are arranged such that a longitudinal axis of the means for fixing the band is orthogonal to the hinge axis. This allows a particularly effective determination of the band on a frame or wing.

Preferably, at least one free, frontal end of the cap, in particular the cap designed as a cover, an end face at least substantially occlusive additional cover arranged. Further, the cover may be aligned and / or fixed by the cap, for example. As a result, the interior of the band can be effectively protected against dust deposits, for example.

In the 1 is an exemplary first embodiment of a tape according to the invention 100 with a cap 4 shown, wherein in this case the cap 4 for better visualization of the hinge flap 1 shown separated. The ribbon 100 is presently designed as a roller belt and includes a relatively massive band attachment portion 2 and an adjoining band hinge section 3 with a recess 30 , in particular a longitudinal bore, for receiving a hinge axis S defining, not shown here hinge pin.

The band attachment section 2 is essentially formed as a rectangular body and serves to fasten the band 100 on a frame, not shown, or on a wing, not shown. For this purpose, the band attachment section 2 a back wall 20 on, which can be brought into contact with the frame or wing, not shown. With the help of itself through the band attachment section 2 extending fasteners 5a . 5b , For example, each one screw, the band 100 are attached to the frame or wings, not shown, which in the 2 and 3 is shown. These can be the screws 5a . 5b in the present case by a respective one of the band attachment portion 2 up to the band hinge section 3 extending recess 35a, 35b in the band attachment portion 2 inserted and used. The recesses 35a . 35b So allow accessibility of the fasteners 5a . 5b and cross the recess 30 , In particular, a longitudinal axis runs A the fastener 5a . 5b or the recesses 35a . 35b orthogonal to the hinge axis S ,

The hinge band section 3 is essentially designed as a semicircular body. On an outer surface 36 of the band hinge section 3 are present in the two circumferentially substantially oppositely disposed longitudinal recesses 31 . 32 educated. In particular, the longitudinal depressions 31 . 32 circumferentially to one another in a cap 4 facing angle of about 170 °. The longitudinal depressions 31 . 32 are each substantially as a longitudinal groove and in the transverse direction homogeneously concave, in particular as a valley or groove formed.

The cap 4 in the present case serves to cover the band hinge section 3, in particular the recesses 35a . 35b , This is the cap 4 present as a semicircular cover sleeve with a longitudinal sleeve opening 40 for receiving the band attachment area 3 educated. On both sides of the sleeve longitudinal opening 40 is in each case a longitudinal sleeve end region 41 . 42 defined with which the cap 4 forming a clamping action with the hinge portion band 3 can be brought into engagement. Especially around the sleeve end areas 41 . 42 at least slightly widening to the cap 4 at the band attachment portion 2 opposite side, for example in the direction perpendicular to the hinge axis S , non-destructive on the hinge section 3 postpone and / or can press, is the cap 4 preferably formed relatively flexible. Alternatively, the cap 4 with the sleeve end areas 41 . 42 optionally at the transition area 33 . 34 and / or at the wells 31 . 32 in the direction parallel to the hinge axis S on the band hinge section 3 be deferred.

In a final assembly position 10 as it is in the 2 is shown, the cap engages 4 forming a clamping action with the sleeve end portions 41, 42 on both sides of the hinge portion band 3 to one between the band attachment portion 2 and the band hinge portion 3 arranged transition area 33 . 34 and thereby can the recesses 35a . 35b cover and on the hinge 1 be attached. This is the cap 4 with an inner wall surface 45 on the outer circumferential surface 36 at least in sections, flat and covers the recesses 35a . 35b completely off. In this final assembly position 10 is the cap 4 completely on the band hinge section 3 placed on and is formed by a formed in the direction of the hinge portion 3 biasing force on the hinge tab 1 held clamped.

In a transport position 11 as it is in the 3 is shown is the cap 4 not completely on the band hinge section 3 but essentially only half. The transport position 11 serves a temporary fixation or storage of the cap 4 on the hinge flap 1 For example, for advantageous arrangement in a product packaging and for improved handling before, during and after assembly and / or adjustment of the band 1 on the frame or wing, not shown. The cap 4 In particular, until final final assembly, in which the cap 4 in the final assembly position 10 can be offset in the transport position 11 remain.

In the transport position 11 surrounds the cap 4 with the sleeve end areas 41 . 42 the band hinge section 3 on both sides to approximately in an area with the largest cross section of the hinge portion band 3 , The sleeve end area 41 . 42 are while forming a clamping action in each case in the wells 31 . 32 stored or fixed. In this transport position 11 enters the cap 4 for example, by pressing the cap 4 in the direction perpendicular to the hinge axis S until the sleeve end areas 41 . 42 into the wells 31 . 32 engage or alternatively by inserting the cap 4, in particular the sleeve end 41 . 42 , in the longitudinal depressions 31 . 32 parallel to the hinge axis S , In this transport position 11 corresponds to one between the inner wall surface 45 the cap 4 and the outer circumferential surface 36 of the band hinge section 3 trained, maximum distance B essentially a radius R the recess 30 , This will make the cap 4 on the hinge flap 1 held effectively and can - for example, for accessibility of fasteners 5a . 5b - parallel to the hinge axis S moved and if necessary from the hinge flap 1 be removed.

After assembly and adjustment of the band 100 on the frame or wing, not shown, the cap 4 in a relatively simple manner in the final assembly position 10 be offset by the cap 4 for example, by pressing or applying force to the cap 4 in the direction perpendicular to the hinge axis S until the on the hinge band section 3 preloaded sleeve end regions 41 . 42 each from the depression 31 . 32 slip out and into the transition area 33 . 34 slip or intervene. Alternatively, the cap 4 from the hinge flap 1 be removed and parallel to the hinge axis S on the hinge strap 1 be pushed in or pushed, in particular with the Hülsenendbereichen 41 . 42 each in the transition region 33, 34. By now each in the transition region 33 . 34 acting preload force of the sleeve end regions 41 . 42 becomes the cap 4 on the hinge flap 1 particularly effectively clamped. In this final assembly position 10 lies the inner wall surface 45 the cap 4 on the outer circumferential surface 36 of the band hinge section 3 essentially flat, so that advantageously an optical impression of a single component, in particular without recognizable fastening means 5a . 5b of the band 100 , as well as a protective effect is possible, for example against dust deposits on the hinge pin in the region of the recesses 35a . 35b ,

For further protection and / or further fixation can optionally on one or both end faces 43 . 44 the cap 4 in addition, a cover, not shown, in particular a recess 30 closing lid, be arranged.

In the 4a ) to c) is an exemplary second embodiment of a tape according to the invention 200 shown. This band is designed as a so-called "Aufschraubband". This is the side of the tape attachment section 2 that of the cap 4 facing away, directly or indirectly on a visible side of a frame or wing, not shown in the drawing. So that the cap 4 covers at least almost the entire visible side of this band, it extends in this embodiment, at least substantially on the side facing away from the frame or the wing side of the band attachment portion 2 and the band hinge section 3 , The cap 4 has a band hinge area 3. ' and a tape attachment area 2 ' on. The inside surface 45 , the outer circumferential surface 36 the band lapel 1 facing, has a contour which is substantially the outer contour of the outer circumferential surface 36 corresponds, so the cap 4 in the final assembly position 10 (please refer 4b ) at least substantially flat on the hinge flap 1 is applied.

The cap 4 has two spaced Abdeckkappenbereiche 41 ', 42' on. Both cover cap areas 41 ' . 42 ' rest in the final assembly position in recesses provided for this purpose 46 . 47 at the hinge portion 3 and at the band attachment portion 2 are arranged.

At the in 4a ) to c) illustrated second embodiment is at the hinge portion band 3 in addition to the recess 46 one farther from the plant side of the hinge 1 removed first well 31 intended. As in 4a ) is recognizable, locked in this the cap with its Abdeckkappenbereich 41 ' whereas the cover area 42 ' engaged with the recess 47 located. In the transport position 11 is the cap 4 accordingly, for example, about one through the Abdeckkappenbereich 42 ' formed pivot axis relative to the finished assembly position 10 pivoted. As by comparing the 4a ) and 4b) is obvious, the cap can 4 in a simple way from the transport position 11 in the final assembly position 10 be shifted by pointing to this one approximately in the direction of the arrow F acting force is exercised.

The in the 5a ) to c) illustrated third embodiment of a tape according to the invention 300 essentially corresponds to the previously described second embodiment 200 , To avoid repetition, reference is therefore made to the relevant description. In the following, only the differences from the second embodiment will be discussed.

In the third embodiment 300 the first recess is missing 31 of the band hinge section. So that the cap 4 nevertheless in a transport position 11 can be mounted is at the band attachment portion 2 a depression 37 provided by the contact surface of the band attachment portion 2 farther away than the recess 47 is arranged. In the transport position 11 is located, as in 5a ) is recognizable, the Abdeckkappenbereich 41 ' already in the recess 46 of the band hinge section 3 whereas the cover area 42 ' in engagement with the depression 37 located. A shifting of the cap 4 from the transport position 11 in the final assembly position 10 in turn, by applying a force F take place by overcoming an elastic force of the Abdeckkappenbereich 42 ' from the depression 37 into the recess 47 is relocated.

It should be understood that the scope of the present invention is not limited to the embodiment described. In particular, the design of the cap and the arrangement of the cap on the tape in the transport position can - without the core of the invention change - be quite modified. For example, in an alternative embodiment, the covering cap may be mounted with a first end sleeve region in the transition region and with a second end sleeve region in a depression in the transport position. Furthermore, it is possible, in the transport position, to fix the covering cap alternatively to the band fastening portion, for example to a device formed thereon, such as at least one depression.
