Description

The present invention relates to a fitting arrangement for a window or door shutter with a shop-side fitting part designed for fastening to the shutter hinge of the window or door shutter and a wall-side fitting part designed for fastening to a stationary wall section, the shop-side fitting part and the wall-side fitting part being rotatable about a shop belt axis are connected to one another and can be locked in at least one rotational position by means of a latching mechanism, the latching mechanism comprising at least one latch-side latching element which is non-rotatable relative to the fitting part on the shop side and a latching element which cooperates with the latching element and non-rotatable relative to the fitting part on the wall side, the latching element on the latch side and the latching element on the wall relative to one another displaceable in a direction of movement parallel to the loading belt axis between an engagement position and a non-engagement position are, and wherein at least one spring element for biasing the shop-side locking element or the wall-side locking element is provided in the engagement position.

Revolving window or door shutters are usually attached to a frame or to the masonry using hinges or clamps. Various types of shop brackets are used to hold shutters or shutters open on the wall in order to prevent them from slamming shut.

The US 2014/0259532 A1 discloses a hinge, the legs of which can be fixed in a predetermined position by means of a latching device. The locking device comprises two locking elements, one of which is axially displaceable and biased into an engagement position. The teeth of the locking teeth are chamfered so that the hinge can be turned even when the locking elements are engaged.

In the case of fitting arrangements of the type mentioned at the outset, the shop holder is, as it were, integrated into the shop conveyor. This has the advantage that the shop holder can be easily reached from the inside of the window without the user having to lean out of the window. Belt fittings with integrated shop holding function are also referred to as "latch holders".

It has been shown that rigid locking brackets can break in strong winds. Apart from the corresponding damage, this represents a considerable risk of an accident. Another problem with known latching brackets is that they are relatively large and conspicuous.

It is an object of the invention to provide a fitting arrangement with a shop holder integrated in the shop belt, which takes up little space and does not tend to break even in strong winds.

The problem is solved by a fitting arrangement with the features of claim 1.

In a fitting arrangement according to the invention, the latching element on the shop side and / or the latching element on the wall has a bevel or rounding which, when the fitting parts are rotated relative to one another, at least in one direction of rotation while overcoming the pretensioning force of the spring element, displaces the latching element on the shop side or the latching element on the wall effected from the engaged position to the non-engaged position. Should there be an excessive load on the locking mechanism, for example as a result of violence or due to strong wind or storm, it will automatically unlock and the hardware will not be destroyed. Due to the beveled or rounded shape of at least one locking element, an overload protection for the shop-holder fitting is provided. During normal use of the shutter holder fitting, that is to say in the absence of excessively large forces acting on the shutter belt, the spring element ensures that the shutter is reliably locked in the open position.

According to the invention, it is provided that the wall-side fitting part comprises an arrangement of a block bushing and a block rod projecting therefrom, the wall-side latching element being arranged on a union bushing which engages around the block bushing and which is non-rotatable relative to the latter, but is displaceable along the direction of displacement. The union sleeve can be gripped directly for displacement, so that no separate handle is required and installation space can be saved. In order to further facilitate the displacement of the union sleeve, it can have a specially designed grip section with corrugation or the like. In addition to the block bushing, the coupling bush can also encompass any toothed components and thus further improve the appearance of the fitting arrangement.

It can be provided that a plurality of latching elements on the shop side form a first latching toothing and a plurality of latching elements on the wall side form a second latching toothing, the first latching toothing and / or the second latching toothing having bevel flanks that are beveled and / or rounded on one or both sides. The engagement of two toothings, each comprising a series of tooth-like projections, enables a particularly secure locking of the two fitting parts and thus a reliable store hold function. As soon as the force acting on the locking mechanism exceeds a threshold value, the beveled or rounded tooth flanks of the locking teeth slide over one another, so that the locking is released.

Preferably, the first locking teeth and the second locking teeth each have a circumferential course around the shop belt axis. Specifically, the locking teeth can run completely around the shop belt axis, so z. B. extend along a concentric circle to the shop belt axis. All-round locking teeth enable a particularly space-saving design.

A special embodiment of the invention provides that the first latching toothing is formed on the flat side of a shop-side, disk-shaped or ring-shaped toothing component and / or that the second latching toothing is formed on the flat side of a wall-side, disk-shaped or ring-shaped toothing component. Such crown wheel-like toothed disks or toothed rings are particularly simple and inexpensive to manufacture. In addition, they take up little space.

A further embodiment of the invention provides that at least one disk-shaped or ring-shaped toothing component is accommodated in a sleeve of the fitting arrangement. If two disk-shaped or ring-shaped toothing components are provided, it is preferred that both are accommodated in the same sleeve of the fitting arrangement. Gearing components accommodated in the sleeve are not recognizable from the outside, which gives the fitting arrangement a particularly appealing appearance.

The block rod can be guided through an elongated hole in the union sleeve in order to enable the union sleeve to be displaced with respect to the block sleeve when the block rod is stationary. Such an elongated hole provides suitable stops for the displacement movement. If the block rod lies laterally against the edges of the elongated hole, the form-fitting engagement between the block rod and the union sleeve ensures that the union sleeve is secured against rotation with respect to the shop hinge axis. If required, however, additional positive locking features between the union sleeve and the block bushing or the block rod can be effective.

For a rotatability of the shop-side fitting part with respect to the wall-side fitting part, a pin which can be coupled to the shop-side fitting part can be mounted in the block bushing so that it can rotate about the shop belt axis. This enables a particularly simple and space-saving construction.

A special embodiment of the invention provides that at one, in particular upper, pin end of the pin, at least one form-fitting feature is provided, which can be brought into engagement with a complementary form-fitting feature of the shop-side fitting part, in particular a hinge bush. For example, a hexagonal profile or the like can be provided as a positive locking feature. The pin can be easily coupled to the fitting part on the shop side using the positive locking feature.

As an alternative or in addition, at least one form-locking feature can be provided on a, in particular lower, pin end of the pin, which can be brought into engagement with a complementary form-locking feature of a toothed component on which the latching element on the shop side is provided. In particular, a hexagonal profile or the like can be provided as a positive locking feature, which engages in a correspondingly profiled recess in the toothed component. This ensures a reliable coupling of the pin to the toothed component in a simple manner.

A further embodiment of the invention provides that the latching element on the shop side and / or the latching element on the wall can be fixed in the non-engaged position. If the locking elements are fixed in the disengaged position, the shop-side fitting part can be freely rotated relative to the wall-side fitting part without the spring force having to be overcome. A user can fix the locking elements in the disengaged position thus opening and closing the shutter or door conveniently and without excessive effort.

Preferably, the fixing of the latching element on the shop side and / or the latching element on the wall side in the disengaged position can be released if necessary by actuating a handle of the fitting arrangement. By operating the handle, a user can quickly and easily move the locking elements into the engaged position and thus lock the drawer.

A pivotable lever can be provided as a handle, one lever end of which is designed for engagement in a recess in the wall-side fitting part and the other lever end of which forms an actuating section. A handle in the form of a pivotable lever enables a particularly simple construction. In particular, the longitudinal axis of the lever can extend essentially parallel to the shutter hinge axis, so that the installation space required in the radial direction can be kept small. An axially aligned lever fits harmoniously into or into an axially aligned union sleeve. The lever end forming the actuating section can protrude from an underside of the sleeve, so that it can be easily pressed or gripped, but does not take up any installation space in the radial direction.

A fitting arrangement according to the invention can comprise a control link which is non-rotatable relative to the fitting part on the shop side and which engages with the handle when the fitting part is rotated relative to the fitting part on the wall in the direction of a shop opening position, in order to actuate the handle as required to release the fixation. Such a control link can be formed, for example, as a recess in a disk-shaped component. The control link allows the locking elements to be automatically transferred into the engagement position when the window or door shutter is opened be provided. This further simplifies the operation of a shop keeper.

The control link can in particular be formed on a link plate which is attached directly or indirectly to the fitting part on the shop side. Such a link plate is particularly simple and inexpensive to manufacture.

Further developments of the invention are also specified in the dependent claims, the description and the accompanying drawings.

The invention is described below by way of example with reference to the drawings.

is a top view of the in Fig. 2 Fitting arrangement shown.

In the Fig. 1-5 Fitting arrangement 11 shown comprises a block rod 13, at one end 14 of which a block bushing 15 is fastened. The other, free End 17 of the block rod 13 is designed for insertion into a wall-mounted fastening component (not shown). The block bushing 15 is penetrated by an elongated pin 19, at its upper end 20 a hexagonal profile 21 and at its lower end 22 a square profile 23 and a threaded section 24 is provided. By means of a bearing bush 25 and a washer 27, the pin 19 is rotatably mounted in the block bush 15 about its longitudinal axis L. As especially in Fig. 3 is recognizable, the hexagonal profile 21 of the pin 19 protrudes from the block bushing 15 and is in positive engagement with a band bushing 29 which is designed for fastening to a shutter band of a window or door shutter (not shown). For this purpose, the upper section 30 of the band bushing 29 has an asymmetrical cross section, as in FIG Fig. 5 can be seen.

In Fig. 3 it can be seen that the pin 19 is in the area of its lower end 22 via the square profile 23 in positive engagement with a toothed disk 35, on one flat side of which a toothing 50 ( Fig. 1 ) is provided. The toothing 50 comprises a plurality of teeth 51 and has a course running with respect to the longitudinal axis L of the pin 19. Furthermore, a link washer 37 is provided, which is coupled to the toothed washer 35 in a rotationally secure manner with the pin 19 via the threaded section 24.

A sleeve-like sleeve 39 surrounds the block sleeve 15 and the toothed disk 35. Furthermore, an annular nut 41 is screwed onto the sleeve 39 from above by means of screws 43. In the assembled state of the fitting arrangement 11, the block rod 13 is guided through an elongated hole 45 which is formed by the arrangement of the union bush 39 and union nut 41. The union bush 39 can thereby be displaced along the longitudinal axis L of the pin 19 by a predetermined stroke, but cannot be rotated with respect to the block bush 15.

The sleeve 39 is provided on its underside with a recess 47 for receiving the toothed disc 35. On an axial side of this recess 47, a toothing not shown in the figures is formed, which is complementary to the toothing 50 of the toothed disk 35. If the sleeve 39 in the in Fig. 3 is shown lower end position, the teeth 50 of the toothed disc 35 engages in the teeth of the coupling sleeve 39, whereby rotation of the pin 19 about the longitudinal axis L relative to the block bush 15 is hindered. A compression spring 55 ensures that the sleeve 39 is biased into this lower end position or engagement position. If, however, the sleeve 39 is in a compared to the in Fig. 3 engagement position shown raised non-engagement position, the teeth 50 of the toothed disc 35 does not engage in the teeth of the coupling sleeve 39 and the pin 19 is freely rotatable about its longitudinal axis L in the block bushing 15.

A lever 56 is pivotably mounted on the union nut 39 by means of a bearing pin 57. The pivot axis S extends in the illustrated embodiment at right angles to the longitudinal axis L of the pin 19. While a latching hook 61 is provided on the upper lever end 58 of the lever 56, the lower lever end 59 of the lever 56 forms an actuating section 63. The latching hook 61 is for one if necessary, engagement in a circumferential locking groove 65 of the block bush 15 is formed. A spring 67 biases the lever 56 into the corresponding fixing position. However, the latching hook 61 of the lever 56 can only engage with the latching groove 65 of the block bush 15 when the union bush 39 is in a raised non-engagement position.

In the assembled state of the fitting arrangement 11, the block rod 13 is fastened in a generally known manner to a stationary wall section, while the band bushing 29 is fastened directly or indirectly to a window or door shutter. To open or close the shutter or door, the Pin 19 are rotated relative to the fixed block rod 13, wherein the longitudinal axis L of the pin 19 forms the tray hinge axis. It goes without saying that a plurality of fitting arrangements 11 can optionally be provided for mounting a window or door shutter.

The toothing 50 of the toothing disk 35 and the toothing of the union bush 39 form a latching mechanism by means of which the window or door shutter can be locked in the open position and / or in the closed position with respect to the associated window or door opening. If the locking mechanism as in Fig. 3 is active, a rotational movement of the pin 19 and thus an opening or closing movement of the window or door shutter is blocked in principle. However, since the toothing 50 has teeth 51 with oblique flanks 69, the latching mechanism unlocks when a sufficiently high torque is exerted on the pin 19. Specifically, the oblique flanks 69 of the teeth 51 slide on the flanks of the associated opposing teeth when a threshold torque is exceeded Union sleeve 39 along and thereby push the sleeve 39 overcoming the biasing force of the compression spring 55 according Fig. 3 upwards, whereby the meshing engagement is canceled. That means the locking mechanism "rattles over". In this way, the inclined flanks 69 of the teeth 51 ensure reliable overload protection of the locking mechanism. If necessary, the flanks of the teeth provided on the coupling sleeve 39 can also run obliquely. In addition, the teeth 51 and, if appropriate, the teeth provided on the union sleeve 39 can be rounded instead of beveled, or both beveled and rounded.

The union sleeve 39 can be moved by a user manually into the non-engagement position and fixed in this. For this purpose, the user grips the sleeve 39 at two opposite handle sections 70 and moves it relative to the wall-mounted block bush 15 - starting from the in Fig. 3 shown position upwards. The locking hook 61 of the lever 56 gets into the Locking groove 65 of the block bush 15 and then holds the sleeve 39 against the force of the compression spring 55 in the raised non-engagement position. In this state of the fitting arrangement 11, the user can freely pivot the associated window or door shutter. To reactivate the drawer holding function, only the swivel lever 56 has to be gripped on the actuating section 63 and counter to the force of the spring 67 Fig. 3 can be pivoted counterclockwise, so that the latching hook 61 is moved out of the latching groove 65 and the union bush 39 is pushed back into the engagement position by the force of the compression spring 55. The toothing 50 of the toothing disk 35 then engages again in the associated toothing of the union bush 39.

When the lever 56 is in the fixing position and the pin 19 is rotated in accordance with a direction of opening of the shop, a control link 75 formed on the link plate 37 comes into engagement with the actuating section 63 of the lever 56 and ensures that it is automatically pivoted into a release position. The control link 75 is designed in such a way that the lever 56 comes into the release position just when the window or door shutter has reached an open position. This means that the shutter hold function is triggered automatically as soon as the window or door shutter is fully open.

The direction in which the sleeve 39 is to be displaced in order to deactivate the drawer holding function is indicated by an information symbol 77. The operation of the fitting arrangement 11 is therefore simple and intuitive.

Due to the overload protection formed by the oblique flanks 69 of the teeth 51, the fitting components are not damaged in a fitting arrangement 11 according to the invention, even in the case of strong wind or storm. Another advantage of the invention is that the space required by the fitting arrangement 11 is comparatively small. In particular in the radial direction with respect to the loading belt axis L, the space requirement is small due to the preferred use of sleeve-shaped and disk-shaped components.
