Description

 Band for pivotally connecting a wing to a frame

The invention relates to a band for the pivotable connection of a wing to a frame, in particular a door leaf to a door frame, with a housing attachable to the frame and with a fastened to the wing pivot bracket which is mounted in the housing.

Such a band is known from EP 1 400 646 B1. It serves to be concealed in the rebate of the combination of frame and sash profiles. As a result, it is not visible from the outside, whereby the optical impression given by the frame / wing combination over conventional bands is improved and whereby the band is secured against external attack with the wing closed. Such covertly arranged bands are thus characterized by a visible from the outside bands improved security against burglary. To a hidden tape even in so-called Aufdeckanordnungen in which frame and / or wing profiles have projections that cover the other profile outside partially closed with the wing closed, can use the pivot axis in the housing of the frame member when pivoting along in provided opposite walls provided, guide surfaces having guideways movable. This causes the wing when pivoting not only around the Pivot axis pivoted, but also shifted relative to the rebate space to the outside. A collision of the Aufdeckanordnung causing projections with the other profile is thereby prevented in a variety of profile combinations.

In the previously known from EP 1 400 646 B1 band, the guideways are arranged in lids of the housing, which are bolted to the rest of the housing. They serve to accommodate slides, in which in turn the pivot axis is mounted.

A disadvantage of this band, that a substantial part of the holding and actuating forces must be introduced via the guideways in the frame. It is therefore necessary, on the one hand, to make the covers sufficiently stable. On the other hand, a snug fit after screwing must be ensured, which in practice requires pinning between the covers and the housing. In addition, the band is difficult to assemble due to the large number of components and also quite complicated in its production due to the required for the mobility of the pivot axis teeth on the housing and the swivel bracket.

The invention is therefore an object of the invention to provide a tape for concealed installation, which is characterized by a simple assembly of its components and its high load capacity. In addition, the band should be relatively inexpensive to produce.

This object is achieved by the reproduced in claim 1 band. Due to the fact that the swivel bracket comprises a guide slot with concentric guide surfaces and the housing has a guide element on which the guide surfaces are guided, so that the swivel bracket can be displaced relative to the housing along the path predefined by the guide slot, the swivel bracket describes a guide during pivoting the curvature of the guide slot defined trajectory, so that the wing when opening receives a component of movement, which in the closed state facing each other, the folding area forming sides of the wing and the frame of- away from each other. The tape according to the invention is therefore also suitable for Aufdeck- arrangements. Due to the leadership of the guide slot on the guide element of the housing, a two-dimensional force transmission between the swivel bracket and the housing can be realized, so that the tape is also suitable for high loads. Since the pivot axis of the hinge bracket is stationary, no complex teeth or separately mounted sliders are required, which has a positive effect on the associated with the production of the tape according to the invention effort. A tape which is also suitable for concealed installation is known from EP 887 501 B1. In this band, the hinge bracket is curved in a circular arc and engages in a circular arc-shaped groove in a holding part. In this embodiment, as the opening angle increases, the area over which forces are transmitted between the wing and the frame decreases. This is especially of considerable disadvantage, as the highest forces are to be expected just when the wing is open.

In a particularly preferred embodiment of the band according to the invention, the guide surfaces of mutually facing sides are selectively formed fastened to each other or separable components of the pivot bracket. As a result of this measure, the band according to the invention can be joined together particularly simply by firstly bringing the one component into contact with the guide element and then fastening the other component in the case of separate components.

The attachment can - particularly preferably - done by means of screws.

Enforcing the latter - as particularly preferred - the guide element in extending in the direction of elongate slot-shaped openings, so a complete swinging out of the guide slot beyond the guide member, which would lead to a separation of the pivot bracket of the housing, effectively prevented. The slot-shaped openings can therefore preferably be dimensioned and arranged such that their ends delimit the displacement path by which the swivel bracket is displaceable relative to the housing. Due to the dimensioning of the slot-shaped openings, in other words, the maximum opening angle of the wing can be limited to a desired value. Doorstop arrangements, which can be unsightly and pose a risk of tripping, are therefore no longer necessary.

In order to prevent jamming and to reduce the wear of the strip according to the invention, the guide surfaces are preferably each provided with a support of a friction-reducing material. The support may be a separate component. However, it is also possible to produce the support by a firmly applied to the guide surfaces layer or a chemical or physical processing of the guide surfaces.

The hinge bracket can be designed to be split parallel to the hinge axis and comprise a guide part having the guide slot and a fastening part having a leg for attachment to the wing. As a result of this measure, the components of the band to be fastened to the frame on the one hand and to the wing on the other hand can be preassembled first and then the wing can be attached to one another in the frame by mounting the guide and fastening part in the case of guiding and fastening parts which have not yet been assembled. In a particularly preferred development of the split-shaped hinge strap, the latter further comprises a device which makes possible a displacement of the guide and fastening parts relative to one another parallel to the hinge axis and fixation of these two parts in a desired position. An adjustment of the wing in the frame parallel to the hinge axis, also called "vertical adjustment", is then possible in a simple manner.

In order to facilitate the connection of the guide and fastening parts in preassembled modules, a recess is provided in at least one of the end sides of the hinge bracket in a particularly preferred development, in which at a certain opening position of the hinge bracket a displaceable on the housing arranged locking element can be brought into engagement. Due to this configuration, the guide part can be locked in the predetermined open position during the assembly process of the wing, so that it does not have to be held manually during this process. This also reduces the risk that personnel injured during installation of the wing, for example, by pinching a finger between the housing and hinge bracket. Thus, the band according to the invention can be used with differently shaped wings in a simple manner, a mounting member for attachment to the wing is preferably provided, which is designed for mounting of the provided for attachment to the wing leg of the hinge bracket. Only the mounting part then has to be adapted to the conditions predetermined by the wing, for example to the dimension of an existing recess. It is also possible to hold different sized, adapted to different standard situations mounting hardware.

In order to easily accomplish an adjustment perpendicular to the hinge axis, also called "horizontal adjustment", can between the

Leg and the mounting part to be provided at least one spacer. The horizontal adjustment can then be made by changing the number of spacers or by the use of spacers of different thickness. The spacers may preferably be made of thermally insulating material in order to avoid unnecessary cold bridges.

Due to the guidance of the guide element provided on the housing on the guide surfaces of the guide slot provided on the swivel bracket, a low-backlash guidance of the hinge bracket in the housing is already ensured. However, in order to facilitate the assembly of the tape according to the invention and to further improve the guide functionality, in a preferred embodiment of the tape according to the invention, the housing comprises at least one guide track extending concentrically with the guide slot into which a guide extension connected to the hinge bracket guides leading. attacks. Due to this as a result of mechanical overdetermination of the hinge bracket is already positioned in the housing before the guide surfaces forming components of the pivot bracket are assembled. An arduous Inpositionhalten of housing and swivel bracket during assembly is thus avoided. In addition, the game between the pivot bracket and the housing is reduced by the additional guide when opening or closing the wing, which wings with smaller gaps to the frame can be realized. It is particularly preferred to provide in the housing two guideways on opposite sides, wherein in each guideway engages an extension, as a result of this measure the band of the invention as it were used for left and right hinged wings and the game between the swivel bracket and the housing again can be reduced.

In order to be able to introduce forces into the guideways to reduce the load, the extensions are preferably formed in a circular arc.

In order to reduce wear, the guideways and / or the extensions may also comprise pads made of a friction-reducing material.

The swivel bracket is formed in the particularly preferred embodiment is substantially U-shaped, wherein the one free leg of the U forms an abutment side for the wing, on the other free leg of the guide surfaces is formed. Here, the guide surface in an initially separate, then connected to the swivel bracket component, or be incorporated into the swivel bracket itself.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The first exemplary embodiment of the strip according to the invention, designated as a whole by 100 in FIGS. 1 to 4, comprises a housing 1 which is approximately trough-shaped and has the shape of a cuboid. On the narrow sides 2 of the housing 1 over the outer contour of protruding collar 3 are formed, each serving two holes 4 for the passage of a respective fastening screw 5. The longitudinal side of the housing shown on the left in FIG. 1 is formed by a guide element 6 which, in cross section, has the shape of a cylindrical tube which is halved in the longitudinal direction. The guide element 6 comprises three elongated holes L spaced from each other, slot-shaped openings. 7

At both ends where the guide member 6 meets one of the narrow sides 2, i. According to FIG. 1 above and below, the guide element 6 is surrounded by a respective guide track 8 formed concentrically with it, which is designed to be open towards the interior 9 of the housing 1.

Furthermore, the band 100 comprises a swivel bracket 10, which has an approximately U-shaped cross-section. The free leg 11 shown on the left in Fig. 1 comprises two holes 12 for the passage of a respective fastening screw 13, which serves to attach the leg 11 to a wing F (see Fig. 2).

At the other, to the leg 11 approximately parallel free leg 14, a concave guide surface 15 is formed, the radius of curvature of the convex side 16 of the guide member 6 corresponds. The guide surface 15 carries a support 17 made of a friction-reducing material.

Furthermore, the swivel bracket 10 comprises an approximately quarter-rod-shaped component 18, whose convex side 19 has a radius of curvature which corresponds approximately to the radius of curvature of the concave side 20 of the guide element 6. On the concave side 20 three spaced apart in the direction of the longitudinal axis L pads 21 are provided from a friction friction reducing material, which reduce the friction between the component 18 and the convex side 20 of the guide member 6.

Formed on the leg 14 of the swivel bracket 10 of FIG. 1 at the top and bottom and forming a continuation of the guide surface 15 in the direction of the longitudinal axis L are extensions 22 which are formed in a circular arc so that they with the guideways 8, which in turn with gleitreibungsreduzierenden Supports 23 are provided to form Gleitpassungen. The component 18 is screwed to the leg 14 with the aid of three screws 24, which each comprise a spacer 25. The screws 24 pass through the leg 14 in each case in a bore 26 and the guide element 6 in one of the slot-shaped openings 7. The screws 24 are screwed into corresponding threaded bores 28 of the component 18, wherein the supports 21 in slot-shaped openings 29 and the support 17 enforce in holes 30. The spacers 25 are dimensioned such that they are flush with the concave side of the support 30. The convex side 19 of the component 18 forms a guide surface 31, which forms a guide slot 32 with the guide surface 15 of the leg 14, which slidably cooperates with the guide element 6 (see, in particular, FIGS. 3 and 4).

Accordingly, in the mounted state of the belt 100, the guide surface 15 cooperates with the convex side 16, the guide surface 31 with the concave side 20 of the guide element slidably together. At the same time, the projections 22 also engage in a sliding manner in the guide tracks 8, so that the swivel bracket 10 is guided exactly on the housing 1. Since the screws 24 pass through the slot-shaped openings 7, their ends can form stops 27 which limit the maximum opening angle of the pivoting bracket 10 and thus of the wing F to the housing 1 and thus to the frame R. The pivoting of the swivel bracket 10 takes place about a pivot axis S, which is located within the frame R approximately at the lateral edge of the housing 1. The illustrated in FIGS. 5 to 9, denoted as a whole by 200 second embodiment of the tape according to the invention comprises a housing 101, which is also approximately trough-shaped and has the shape of a cuboid. On its narrow sides 102 projecting on the outer contour collar 103 are formed, each of which two holes 104 for the passage of a fixing screw 105 serve. Further, in each collar 103 near the edge of the trough-shaped part 101 'of the housing 101 is approximately centrally provided a further bore 104', through which in each case a further, not shown in the drawing fastening screw in the frame R can be screwed if necessary. The longitudinal side of the housing 101 shown on the right in FIG. 5 is formed by a guide element 106, which in cross section has the shape of a cylindrical tube which is halved in the longitudinal direction. The guide element 106 comprises three longitudinally spaced holes L, 107 spaced apart from each other.

The guide member extends up and down to flat boundary surfaces 108th

Furthermore, the belt 200 comprises a swivel bracket 110, which has a guide part 133 and a fastening part 134.

To the guide member 133, a concave guide surface 115 is formed, whose radius of curvature corresponds to the convex side 116 of the guide member 106. The guide surface 115 is coated with a non-recognizable in the drawing edition of friction-reducing material.

Furthermore, the swivel bar 110 comprises an approximately quarter-bar-shaped component 118 whose convex side 119 has a radius of curvature which corresponds to the radius of curvature of the concave side 120 (see FIG. On the convex side 120 of the component 119 four supports 121 are applied spaced from friction friction reducing material, which reduce the friction between the component 118 and the convex side 120 of the guide member 106.

The component 118 is screwed to the guide part 133 with the aid of three screws 124, which each comprise a spacer 125. The screws 124 pass through the component 119 in each case in a bore 126 and the guide element 106 in one of the slot-shaped openings 107. The screws 124 are screwed into corresponding threaded bores 128 of the guide part 133. The length of the spacers 125 is selected to be only slightly longer than the material thickness of the guide element 106, and the diameter corresponds substantially to the width of the slot-shaped openings 107. The convex side 119 of the component 118 forms a guide surface 131, which forms a guide slot 132 with the guide surface 115 of the guide part 133, which slidably cooperates with the guide element 106, in other words: which holds the guide element 106 so as to slide about the hinge axis S. see Fig. 6 to 9).

Accordingly, in the mounted state of the band 200, the guide surface 115 cooperates with the convex side 116, the guide surface 131 with the concave side 120 of the guide element slidably together. Since the screws 124 pass through the slot-shaped openings 107, their ends can form stops 127 which limit the maximum opening angle of the pivoting bracket 110 and thus of the wing F to the housing 101 and thus to the frame R. The pivoting of the swivel bracket 110 takes place about a pivot axis S, which is located within the frame R approximately at the lateral edge of the housing 101.

At the front ends of both the component 118 and the guide part 133, supports 135 of approximately circular cross-section of friction-reducing material are attached. They slide on actuation of the belt 200 on the respectively adjacent boundary surface 108 from.

As can be seen in particular in Fig. 5, the guide member 133 comprises on its side facing the fastening part 134 two spaced apart in the direction of the hinge axis extensions 136 which at their free end portions thickenings 137 (see also Fig. 6 and 7). The fastening part 134 is provided with a groove 138 which is designed to be complementary in cross-section to the extensions 136. It has on the guide part 133 side facing an insertion opening 139 which extends from the center approximately the same length to the front ends of the fastening part 134 and through which one of the extensions 136 in the groove 138 can be inserted.

A positive connection between the guide part 133 and the fastening part 134 is achieved by inserting one of the projections 136 into the opening 139, the two parts parallel to the hinge axis relative to each other. be pushed so that both extensions are in positive engagement with the groove 138.

In order to be able to fix the guide part 133 and the fastening part 134 in engagement with one another, the end regions of the groove 138 are provided with threaded bores into which threaded spindles 140 can be screwed. An adjustment parallel to the hinge axis (vertical adjustment) can be done by out or inward turning of the threaded spindles 140. The band 200 further comprises a mounting part 141 whose contour is adapted to a recess T in the wing. It comprises a plurality of bores 142, which serve for the passage of fastening screws 143 for screwing to the wing F. Furthermore, threaded holes 144 are provided on the mounting part 141, which serve to screw in machine screws 145 for the purpose of screwing the fastening part 134 on the mounting part 141.

Between the fastening part 134 and the mounting part 141, a spacer 146 is provided, which consists of a thermally insulating material. For the purpose of adjusting the band perpendicular to the hinge axis (horizontal adjustment) spacers 146 can be used in different numbers or different thickness. The division of the pivoting bow 10 into the guide part 133 and the fastening part 134 has the advantage that the frame-side assembly B1 and the wing-side assembly B2 can be preassembled on the frame and on the wing. To attach the wing, it is then only necessary to add the guiding and fastening parts 133, 134 of the bands as described.

So that the guide part 133 does not have to be held manually in an open position during this process, recesses 147 are machined on the end faces of the guide part 133 into which the guide element is bolted to the housing 101. animal elements 148 are pivoted in a certain opening position. The locking elements have at their in Fig. 5 facing away from the viewer side each have a projection which is engageable in two recesses 149 on the housing 101 in engagement. Projection and recesses are arranged so that the projection in the position locking the guide part 133 in the one recess in which the guide member 133 is releasing position in the other recess.
