Abstract

The hinge (100) for doors, windows or the like comprises a frame hinge part (10) and a leaf/sash hinge part (20). The invention provides a covering strip (50, 50') which extends along the gap (26) between the hinge parts (10, 20) and covers over said gap. The covering strip (50, 50') engages over one of the hinge parts (10, 20) with one longitudinal border abutting on the outside, such that said hinge part can be shifted vertically with respect to the covering strip (50, 50'), has a width which corresponds at least to the adjustment travel of the hinge parts (10, 20) with respect to one another, and is connected to the other hinge part (20, 10) along the other longitudinal border. <IMAGE>

Description

The invention relates to a volume of the type corresponding to the preamble of claim 1.

Such a band is known from DE-GM 90 06 439. The height of the sash can be adjusted by means of a screw element which is arranged in a bore in the frame hinge part which is coaxial with the hinge pin axis and which, when it rotates, lifts the hinge pin or the hinge sleeve receiving it.

Depending on the set height of the sash, there is a gap of different sizes between the frame hinge part and the sash hinge part. This gap catches the eye because the adjacent surfaces and edges lie close together and differences can be clearly perceived in this way. This is particularly noticeable in the case of three-part or hinge bands, because the gaps above and below the wing band part can be of different sizes
The invention has for its object to design a band of the generic type so that different height settings of the wing are no longer visible to the naked eye stand out.

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

The cover strip hides the areas of the frame hinge part and the sash hinge part that are adjacent to one another, so that the mutually facing edges are no longer visible and can no longer give off a scale perceptible to the naked eye for the set height of the sash. Of course, depending on the adjustment made, the height of the wing hinge part above the frame hinge part is objectively different, which can easily be determined by a measurement. However, there are no immediately adjacent reference edges. The lower limit of the frame hinge part and the upper limit of the wing hinge part form very widely spaced reference points, the relative position of which is barely perceptible to the naked eye.

In a first basic embodiment, the cover strip is connected to the frame hinge part in the axial direction of the hinge pin, so that it is fixed and the frame hinge part moves up and down relative to the cover strip.

In another basic embodiment, according to claim 3, the cover strip is in constant contact with the wing hinge part in the axial direction of the hinge pin and follows its adjustment movement, wherein it is displaced vertically relative to the frame hinge part.

According to claim 4, the cover strip can be formed as a collar which sits on the outer edge of an overlying the upper side of the frame hinge part of a ring bolt bush arranged in the frame hinge part.

In this case, the hinge pin bushing is designed as a type of hat which overlaps the frame hinge part with the brim. The ring part formed by the brim transmits the forces introduced by the wing hinge part to the frame hinge part. The ring part goes radially (with respect to the Hinge pin) up to the area of the outer edge of the hinge parts and is connected to the collar there. A first possibility is that the cover strip is integrally formed on the hinge pin bush.

Since the hinge pin bushing consists of a suitable plastic and is subject to a corresponding molding process, it is expedient to include the formation of the cover strip in this case.

The alternative according to claim 6 is to design the cover strip as a separate molded part.

In particular, this molded part can be designed according to claim 7.

The shorter leg is used to fix the molded part, while the longer leg forms the cover strip.

A particularly advantageous embodiment is the subject of claim 8 and can be designed according to claim 9 by a lock, which can include inserting the U-shaped molded part from the front and fixing it in the final position reached, for example by snapping in a suitable latching device.

It can be advantageous to give the outside of the cover strip a profiling, which can include a particularly tight fit to the outside of the frame hinge part or a decorative relief-like design.

The invention is for both two-piece and three-piece tapes, i.e. so-called hinge straps, suitable (claim 11).

If, in the case of hinge hinges, the wing hinge part is lifted by lifting the lower hinge pin bushing and the lower cover strip is connected to it, the lower cover strip follows the movement of the wing hinge part during the adjustment.

However, it is recommended for the top cover strip a special tracking device according to claim 12 to avoid gaping the gap at the lower edge of the upper cover strip if the upper hinge pin bushing does not come along when lowering.

It is recommended that the device acts on the upper hinge pin bushing connected to the cover strip (claim 13).

A simple embodiment is a spring that constantly depresses the upper hinge pin bushing (claim 14).

According to claim 15, however, the movement of the cover strip can also be coupled to the movement of the hinge pin, which moves along with the adjustment stroke.

This can be achieved in particular in the manner set out in claim 16.

In the latter case, it is advisable to form the two cover strips present at the two transition points between the frame hinge part and the parts of the hinge hinge part as a mirror image of one another (claim 17).

When the following description refers to "above", "below", "vertical" and the like, such information always refers to the installation position of the belt.

1 to 4 as a whole with the band 100 is a so-called hinge band, which is attached to the front surface 38 of the fixed frame 1, which is only indicated by dash-dotted lines in the figures, and to the front surface 39 of the wing 2 attached wing hinge part 20, which are pivotable against each other about a hinge axis 9 formed by a hinge pin 8 (FIG. 4).

The frame hinge part is fastened to the frame 1 by screws 3 and fixing pins 4, the sash hinge part 20 by screws 5 and fixing pins 6 to the wing 2. The frame 2 and the wing 1 do not abut each other directly, but usually form a fold with a so-called shadow groove 7 the visible side.

The frame hinge part 10 comprises a lower hinge part 11 and an upper hinge part 12, between which the hinge part 13 of the wing hinge part 20 engages. The hinge pin 8 extends vertically through the hinge parts 11, 12, 13.

The sash hinge part 20 is arranged in the hinge hinge part 10 to be height-adjustable by a certain distance in the direction of the arrow 14 in order to be able to adjust the position of the sash in the frame. When adjusting the height, the gaps 26 change between the upper limit 15 and the hinge part 11 and the lower limit 16 of the hinge part 13 and the upper limit 17 of the hinge part 13 and the lower limit 18 of the hinge part 12 (see FIG. 2).

In order to conceal this change and in particular not to make different gaps 26 between the boundaries 15, 16 and 17, 18 catch the eye, the gaps between the boundaries 15, 16 and 17, 18 are covered by cover strips 50, which in the Embodiment with one edge 51 on the horizontal and horizontal upper and lower boundaries 16, 17 of the wing hinge part 20 and move up and down with it.

The training in detail is shown in Fig. 4. The hinge pin 8 sits in each of the hinge parts 11, 12 in a hinge pin bushing 30, which in turn is received in a corresponding recess 19 of the hinge parts 11, 12.

In the lower region of the hinge part 11, the recess 19 is formed as a threaded bore 21 into which a nut-like screw element 22 can be screwed, which can be rotated by a turning tool engaging in a hexagon socket 23. When screwing in, the lower hinge pin bush 30 according to FIG. 4 lifts the wing hinge part 20. This leads to the adjustment. The lower hinge pin bushing 30 has, at the upper edge, as shown in FIG. 4, facing the lower boundary 16 of the wing hinge part 20, a collar part 24 projecting radially outwards, which ends with the upper end of the hinge pin bushing 30. From the outer edge of the ring part 24, the cover strip 50 extends from its edge 51 resting on the wing hinge in the form of a collar 25 parallel to the hinge pin axis 9 against the main part of the hinge pin bushing 30 (see also FIG. 5). A circumferential groove 28 is thus formed which is open towards the end of the hinge pin bush 30 remote from the ring part 24 and which receives the edge of the hinge part 11 or 12 there in such a way that an axial movement of the parts 30 and 11, 12 relative to one another is possible. The collar 25 is thin-walled, since it has only an optical function and does not have to transmit any forces. It is only supposed to be the gap 26 cover. In any case, the cover strip 50 lies in the area of its edge 52 (FIG. 5) facing the main part of the hinge pin bushing 30 on the outside of the hinge part 11 of the frame hinge part 10, that is to say its outline is shaped in accordance with the outline of the hinge part 11, as shown in FIG. 6 shows where this floor plan is approximately square with slightly convex rounded sides. The cover strip 50 and the collar 25 are only present on the visible sides according to FIGS. 5 and 6, but not on the rear side 27.

In the upper hinge part 12 of the frame hinge part 10, a same hinge pin bushing 30 is provided, which is only reversed, i.e. is arranged in mirror image to the horizontal central plane 39 of the band 100 and in which the collar 25 forming the cover strip 50 'extends upwards from the ring part 24. Otherwise the function is the same.

The lower hinge pin bushing 30 is carried along by the screw element 21 and is always in contact with the lower boundary surface 16 of the wing hinge part 20. In the case of the upper hinge part 12, in the exemplary embodiment according to FIG. 4 there is a helical compression spring 31 which is put under tension by a cover disk 29 pressed into the recess 19 of the hinge part 12 and is only indicated by dash-dotted lines in FIG. 4 and which holds the hinge pin bushing 30 or the cover strip 50 '' in contact with the upper boundary surface 17 of the wing hinge part 20.

Another embodiment of a device which keeps the upper cover strip 50 'in contact with the upper boundary surface 17 of the sash hinge part 20 even when the sash hinge part 20 is lowered is shown in FIGS. 9 to 11, in which the hinge pin bush 30 of FIG. 5 and 6 is used. 5 and 6, the hinge pin bushing 30 has at its end adjacent to the collar 25 six notches 40 which are evenly distributed over the circumference and extend to a certain depth, are divided by the six segments 41, 42 of equal size in the circumferential direction, which alternately follow one another in the circumferential direction. Just as deeply extending recesses 43 are arranged behind the segments 42, so that the segments 42 form all-round free-standing axial tongues which, on the side facing the hinge pin, have a slightly radially projecting hook-like projections 44 at their free end against the inside of the hinge pin bushing 30. Thanks to the elasticity of the tongue-like segments 42, they can be pressed backwards against the recess 43 by the radial extension of the projections 44.

This property is used in the lower hinge pin bushing in FIG. 9, in which the projection 44 is pressed away from the hinge pin 8, the tongue-like segment 42 escaping into the recess 43.

In the case of the upper hinge pin bush 30, however, the hinge pin 8 has an all-round groove 45 into which the projection 44 can engage when the hinge pin bush 30 is on the upper edge 46 of the eccentric sleeve 47 seated in the wing hinge part 20 or the lower edge of the upper cover strip 50 ' abut the upper boundary surface 17 of the wing hinge part 20. The projection 44 hooks in this position in the all-round groove 45, so that the hinge pin bushing 30 is carried along during the up and down movements occurring during the adjustment.

1 to 6, the cover strip 50 is formed in one piece with the hinge pin bush 30, in the two-part hinge 200 of FIGS. 7 and 8 a separate molded part 35 is provided to form the cover strip 50. The hinge pin bushing 30 again has a ring part 24 projecting radially outwards from its upper edge, which has a recess 32 along its edge shaped in accordance with the outline of the hinge part 13, into which a shorter leg 33 of the shape formed by an angular profile at a right angle partially engages 35, the longer leg 34 forms the cover strip 50 and tightly encloses the upper edge of the hinge part 11 of the frame hinge part 10 in the manner shown in FIG. 8. Since the adjustment or lifting of the wing hinge 20 takes place via the screw member 22 while lifting the hinge pin bushing 30, the upper edge of the molded part 35 always remains in contact with the lower boundary 16 of the wing hinge part 20. The molded part 35 has a U-shaped outline, 7 and 8 so that it can be inserted into the groove 32 from the front with the shorter leg 33. Appropriate shaping will lock into the final position.

Starting from the situation according to FIG. 8, the dimensioning is such that the distances 36 and 37 at least correspond to the strokes available for lowering or lifting the wing hinge part 20 relative to the frame hinge part 10. This naturally also applies accordingly to the band 100 of FIGS. 1 to 6.

In the case of the band 100, the cover strips 50, 50 'consist of the material of the band bolt bush 30, i.e. made of a suitable plastic. For the belt 200, the materials can also be different, i.e. the cover strip 50 can also be formed, for example, from metal. The visible outer surface of the cover strips 50, 50 'can carry a profile or a relief, which are included in the design of the outer appearance of the strips 100, 200.
