Description

The invention relates to a hinge fitting for a window or door shutter according to the preamble of claim 1. Furthermore, the invention is directed to a hinge fitting for a window or door shutter according to the preamble of independent claim 9.

A hinge fitting of this type is described in EP 0 189 813. A bearing housing for an adjustable bolt is arranged in a rotationally fixed manner on the band sleeve of at least one drawer strip of this hinge fitting, the bolt engaging in a latching recess provided in the block rod or in the block in the open position of the drawer and thereby the open drawer being ascertainable. To release the locked shutter, the bolt is pulled out of the locking recess, whereby the shutter strap and the block rod are uncoupled from each other, so that the shutter can then be pivoted in the direction of the closed position.

It is important for the assembly of the block rod of such a shop fitting that the block rod must be aligned and fastened in a very precisely predetermined position relative to the wall or the window or door frame. Even a slight horizontal angular deviation of the block rod from the specified mounting position leads to an incorrect definition of the swivel range of the shop. This means that the shutter in its position to be locked does not run parallel to the wall, but either protrudes from the wall or cannot be swung open until it reaches the locking position. Even slight dimensional deviations from the specified assembly position can be so noticeable due to the length of the store that these deviations are generally not acceptable. The incorrect assembly of the locking device must then be remedied by installing the block rod correctly and not without problems.

Another problem with lockable stores occurs when unlocking the locked store. Regardless of whether the locking device is arranged at the end of the store on the hinge side or away from the hinge, the lock must usually be released with one hand in order to unlock the store and, at the same time, the shutter must be pivoted towards the window with the second hand. The pivoting of the shop is either associated with a great deal of effort, since only a very short lever is available when gripping the end of the shop on the hinge side, or with a leaning out of the window in order to grasp the shop as close as possible to its far end can. A one-handed unlocking with simultaneous closure feed is not without problems possible in this way.

In order to automatically give the shop an impulse in the direction of the closed position when the shop is unlocked, various push-off devices for shops have been proposed in the past. These are spring elements which are fastened to the wall and against which an engagement element fastened to the shutter is guided when the shutter is opened, the spring element being tensioned by the engagement element when the loading is locked. Usually, the spring element is fastened to the wall in the region of the end of the drawer that is remote from the band, in order to thereby lengthen the lever arm acting when the drawer is closed and thus to reduce the force required for closing. The spring element is usually integrated into this when using a locking element located away from the belt.

The problem with a push-off device of this type is that the spring element is exposed and can therefore become contaminated or corroded by the weather, so that the functionality of the push-off device can no longer be guaranteed. Even when painting the wall of the house to which the locking or push-off device is attached, the functionality can be very badly affected by paint.

If the locking device is concealed in the hinge fitting, as for example in EP 0 189 813 already cited, the push-off device attached to the wall in the area away from the belt is still visible when the shutter is closed, which is often viewed as impairing the overall visual impression.

The object of the invention is to provide a hinge fitting for a window or door shutter, in which an incorrect determination of the pivoting range of the shutter caused by incorrect mounting of the block rod can be compensated, in particular the functional reliability of an existing push-off device for the store and the push-off device being improved should not affect the overall visual impression even when the store is closed.

This object is achieved according to the invention by the features of independent claims 1 and 9.

The pivotable mounting of the stop and / or locking unit on the block rod around its hinge pin and the provision of a fixing unit, by means of which the stop and / or locking unit can be fixed in different positions relative to the block rod, ensures that the stops are at an obliquely inserted block rod - And / or locking unit can be pivoted relative to the block rod so that the shutter can be aligned parallel to the wall in the open position and in particular comes into contact with the stop unit provided on the hinge fitting or can be locked with the locking unit provided on the hinge.

In this way, the time-consuming reassembly of the block, which may have been necessary up to now, is eliminated.

According to an advantageous embodiment of the invention, the fixing unit comprises two fixing elements which are attached to the and / or locking unit are adjustably mounted and can be supported on two substantially opposite areas of the block rod. At least one fixing element is preferably designed as a screw, in particular as a grub screw, whose end facing away from the actuating end engages laterally on the block rod.

By simply loosening the screws, the stop and / or locking unit can be pivoted relative to the block rod until the desired alignment is achieved. The screws are then screwed in until the ends facing away from the actuating end engage laterally on two opposite regions of the block rod and thus prevent the stop and / or locking unit from pivoting relative to the block rod.

According to a further preferred embodiment of the invention, at least one fixing element consists of an axially immovable guide screw, which is rotatably mounted on the stop and / or locking unit, and a support element screwed to it with at least one guide projection, in particular designed as an inclined surface, with the stop and / or locking unit at least one inclined guide is provided, which cooperates with the respective guide approach of the support element. The support element can be moved along the inclined guide by rotating the guide screw, as a result of which it can be moved in the direction of the block rod for supporting the stop and / or locking unit on the block rod.

By guiding the fixing element along an inclined guide, the guide screw can be aligned essentially parallel to the block rod and can thus be actuated from the front of the block rod. This ensures that the fixing elements even when the block rod is installed close to the side wall of a window recess for adjusting the stop and / or locking unit remain accessible.

According to a further preferred embodiment of the invention, on the stop and / or locking unit, a displaceably mounted, in particular spring-loaded latching projection is provided, which engages in a latching recess provided in the loading belt in the open position of the store. The side surfaces of the locking projection are preferably designed as inclined surfaces. The design of the side surfaces of the latching attachment as inclined surfaces ensures that in the event of an inadvertent pivoting of the store from the latched position in the direction of the closed position of the store without actuating the locking unit, the latching attachment is not sheared off, but rather by those starting at the inclined surfaces of the latching attachment Side walls of the recess is pushed back.

With regard to a push-off device of the store from its open position to the closed position according to the invention, the attachment of a clip spring which essentially encompasses the hinge pin and can be tensioned by a driver in the area between the loading tape and the block rod ensures that the push-off device is practically invisible and against external influences such as dirt, paint or corrosion caused by the weather, is largely protected. In addition, since there is usually only a small amount of space available in the area of the hinge fitting, the design as a clip spring is advantageous since this ensures that the push-off device takes up very little space.

According to a further advantageous embodiment of the invention, a recess is provided on the underside of the shop belt, at least in the region of the band sleeve, in which the clip spring is arranged and fastened with one end, the driver being provided on the block rod, engaging in the recess and between the Closed and dome position of the store is freely movable in the recess.

The arrangement of the clip spring in a recess in the shop belt further increases the protection of the clip spring from external influences. In addition, an even better optical concealment of the clip spring is achieved.

According to a further preferred embodiment, a cover surface is provided on the region of the block rod facing the recess, which cover substantially the recess provided in the loading belt, the driver projecting beyond the cover surface and engaging in the recess. As a result, the clasp spring is completely sealed off from external influences, the driver being able to be provided as an attachment on the surface of the block rod which forms the cover surface or can engage through an opening in the cover surface into the recess provided in the loading belt.

Further advantageous embodiments are specified in the subclaims.

FIG. 1 shows a block rod 1, at the end of which a hinge pin 2 is arranged, a locking unit 3 being pivotably mounted on the block rod 1 around the hinge pin 2. On the locking unit 3, a spring-loaded locking projection 4 with an actuating handle 5 is slidably mounted.

In a hole 6 provided with a thread in the locking unit 3, a grub screw 7 is arranged, the end 9 facing away from the actuating end 8 engages laterally on the block rod 1.

On the opposite side of the block rod 1, a guide screw 11 with a support element 12 screwed thereto is arranged in a cavity 10 in the locking unit 3, which is accessible from the outside via a recess 10 '. The guide screw 11 is supported with its head 13 arranged in the recess 10 ′ and with its widened end 14 on two stops 15, 16 of the locking unit 3 and is therefore axially immovable but rotatable relative to the locking unit 3.

The support element 12 has a guide projection 17 designed as an inclined surface, which bears against an inclined guide 18 provided in the cavity 10.

The end of the support element 12 facing the block rod 1 is curved in a convex manner 29 and lies against the side of the block rod 1 opposite the grub screw 7.

In Figure 1, the locking unit 3 is fixed relative to the block rod 1 by the grub screw 7 and the support element 12 in a first end position, which is achieved by pivoting the locking element 3 clockwise.

Figure 2 shows a section along the line AA in Figure 1, wherein it can be seen that the guide projection 17 of the support element 12 cooperates with the oblique guide 18 of the locking unit 3 and at the same time a second guide projection 17 'is present on the top of the support element 12, which cooperates with a second inclined guide 18 'of the locking unit 3. The support element 12 is concavely curved at its end facing the block rod 1 and bears against the block rod 1 in such a way that the concavely curved region partially surrounds the block rod 1.

In Figure 3, the grub screw 7 is screwed out of the hole 6 and the support element 12 is displaced via the guide screw 11 in the direction of the block rod 1 that the locking unit 3 assumes the end position opposite to the block rod 1 shown in Figure 1.

The end position according to FIG. 3 and any position lying between the two end positions is achieved, starting from the end position in FIG. 1, in that the grub screw 7 is unscrewed in the direction of the open end of the bore 6, whereby the block rod 1 from the position shown in FIG. 1 can be pivoted in the direction of the grub screw 7. Then, for example, an Allen key is inserted into the head 13 of the recess 10 ' Guide screw 11 inserted and twisted. The support element 12 on the guide screw 11 is displaced in the direction of the head 13 by the rotation of the guide screw 11, the support element 12 and the guide screw 11 being moved in the direction of the block rod 1 by the cooperating guide lugs 17, 17 'and inclined guides 18, 18' and the locking unit 3 is transferred from the position shown in FIG. 1 to the position shown in FIG. 3.

The locking unit 3 can then be fixed relative to the block rod 1 by screwing in the grub screw 7.

In the section shown in FIG. 4 along the line AA from FIG. 3, compared to FIG. 2, the displacement of the support element 12 and the guide screw 11 in the direction of the block rod 1 and the displacement of the block rod 1 in the direction of the grub screw screwed out towards the open end of the bore 6 7 recognizable.

By pivoting the locking unit 3 with respect to the block rod 1, the position of the locking projection 4 with respect to the block rod 1 is changed, so that the position of the lock locked with the locking unit 3 can be adjusted.

In FIG. 5, a partially cut-open shop band 19 with a band sleeve 19 'is placed on the band pin 2. At its lower end, the loading belt 19 has an enlarged area or collar 20, in which a recess 21 which is open at the bottom is arranged. A clip spring 22 is arranged in the recess 21. The top of the locking unit 3 is at the same time cover surface 23 for covering the recess 21 when the block rod 1 and the shop belt 19 are connected to one another.

In the section shown in FIG. 6 along the line A-A from FIG. 5, it can be seen that a radially outwardly bent end 24 of the clip spring 22 is held in the recess 21 via a fastening means 25. The store belt 19 is in a position that corresponds to the closed position of the store attached to the store belt 19.

The loading belt 19 has on its collar 20 a locking recess 26 for receiving the locking projection 4 in the open position of the store. On the cover surface 23 for the recess 21, a driver 27 is provided, which is arranged in the recess 21 in the shop belt 19.

When the drawer is pivoted in the direction of the open position, the drawer hinge 19 is rotated clockwise and moved into the position shown in FIG. 7, with the radially outwardly bent free end 28 of the clip spring 22 abutting against the driver 27 before reaching the drawer open position comes and the clip spring 22 is tensioned by the further movement of the store in the open position. When the open position is reached, the catch projection 4 engages in the catch recess 26, as a result of which the shutter is fixed in the open position.

To unlock the store, only the locking lug 4 has to be moved downwards via the actuating handle 5 until it emerges from the locking recess 26, as a result of which the energy stored in the tensioned spring clip 22 rotates the loading belt 19 counterclockwise and thus the loading in the direction of Closed position is pivoted. This impulse acting on the drawer in the direction of the closed position makes it much easier to close the drawer, and it is also possible to unlock the drawer with one hand.
