Description

The present invention relates to a fitting arrangement according to the preamble of claim 1.

Such a fitting arrangement is for example from the WO 02/16716 A1 known. A fitting arrangement which is essentially comparable in terms of type also describes the KR 2010 0024649 A .

Lift-and-slide doors usually have a lifting mechanism which can be actuated by means of a lever and by means of which the door can be raised in order to be able to move it. To secure a lift and slide door in its closed position, a mushroom-head pin can be provided on the door frame, which extends in the closed door position through an opening in the faceplate of the door-side fitting arrangement in order to engage a keyhole-shaped opening in a movable bolt behind the faceplate. In order to engage the mushroom head pin with the keyhole-shaped opening, the lift and slide door is moved into its closed position, so that the mushroom head pin passes through the opening in the face plate and through the larger opening section of the keyhole shaped opening. The lift and slide door can then be lowered by operating its lever using its lift mechanism. At the same time, the lever is used to move the bolt behind the faceplate so that the mushroom head pin is now in the smaller opening section of the keyhole-shaped opening and thus engages behind the bolt, causing the lifting and sliding door in its closed position is secured. However, it is possible to force the lift and slide door from the outside, for example, whereupon the lift and slide door can be pushed open, since the mushroom head pin in the raised position is aligned with the larger opening section of the keyhole-shaped opening in the bolt.

Fitting arrangements with so-called swivel hooks are also known, by means of which lift and slide doors can be secured in their closed position. Such swivel hooks generally have a substantially U-shaped shape and are pivoted into the striking plate opening from above in the closed door position when the lift and slide door is lowered by actuating its lever by means of the lifting mechanism. Such swivel hooks are mechanically coupled to the actuating lever of the door in such a way that the swivel hook is pivoted from its disengaged position into its engaged position at the same time as the lifting and sliding door is lowered, in which it then engages in a striking plate opening. However, even with such fitting arrangements with swivel hooks, it is possible to lift the lift-and-slide door from the outside by force, so that the lift-and-slide door can then be pushed open, even if the free hook end initially engages behind the lower edge of the striking plate opening. This is because the swivel hook can be pivoted from its engaged position to its disengaged position in a raised position of the door, since after the door has been forcibly lifted the weight of the door no longer offers any resistance, which could otherwise prevent the hook from pivoting.

The invention is therefore based on the object of specifying a fitting arrangement with a swivel hook for securing a window, a door or the like, in particular a lift and slide door, which also offers effective burglary protection when an attempt is made to lever out the fitting arrangement.

This object is achieved with a fitting arrangement which has the features of claim 1.

The fitting arrangement according to the invention serves to secure a window, a door or the like, in particular a lift and slide door, to a striking plate and comprises at least one swivel hook which can be swiveled about a swivel axis between an disengaged position and an engaged position and which has an engagement section for engaging in an opening of a striking plate which ends at the free end of the swivel hook. The engaging section is thus that section of the swivel hook which, when in the engaged position, extends through the opening of a striking plate in order to engage behind the edge of the striking plate opening for security purposes. In this case, it is provided that a stop surface, which is oriented transversely to the outside of the engagement section and which faces away from the free end of the engagement section, is formed on the engagement section at a distance from the free end thereof.

In order to ensure that the locking lug or its stop surface can come into contact with the upper edge section of the striking plate opening when the lift and slide door is raised, it is provided according to the invention that the locking lug is formed on the engagement section in an area which is in the engaged position of the Swivel hook is located in the opening of the striking plate or behind it.

For example, the stop surface can be formed by a recessed step which extends from the outside of the engagement section in the radial direction. If one slides along the convex outer side starting from the free end of the engagement section, one arrives at a point at which the outer contour of the engagement section has a jump inwards, which means that the transverse dimension of the hook section decreases suddenly at this point.

When the door is in its closed position and is lowered by actuating its lever by means of the lifting mechanism, the pivot hook is simultaneously pivoted from its disengaged position into its engaged position, being pivoted into the striking plate opening from above. The swivel hook thus extends with its engaging portion through the striking plate opening and engages behind the lower edge portion of the opening, so that the door in its now lowered position cannot be easily pushed open even under the influence of force.

However, the fitting arrangement cannot be levered out either, because in the event that the lift and slide door is lifted from the outside, for example with the aid of a lever tool, the swivel hook and in particular the stop surface formed on its engagement section prevents the swivel hook from being disengaged from the striking plate: If the lift-and-slide door is raised, the swivel hook engages with its stop surface in its engaged position with an upper edge section of the striking plate opening from below, or the swivel hook with its stop surface abuts against the upper edge section of the strike plate opening from behind, thereby pushing open the lift-and-slide door itself in its raised position is prevented. Rather, due to the fact that when it is raised, it engages behind the upper edge section of the striking plate opening with its abutment surface from below, the swivel hook experiences a torque which causes the free end of its engaging section to be pressed all the more strongly against the lower edge section of the striking plate opening, each greater the upward force on the door. For this purpose, the distance between the free end of the engagement section and the stop surface should be greater than the clear width of the opening of the striking plate, which is between the lower edge section of the Strike plate opening, which engages behind the engagement portion of the pivot hook in its engaged position, and the opposite upper edge portion of the strike plate opening, with which the stop surface of the engagement portion comes into engagement. The swivel hook is thus wedged to a certain extent in or on the striking plate opening, so that a lift and slide door equipped with the fitting arrangement according to the invention cannot be opened by force even if it is lifted from the outside, for example.

Preferred embodiments of the fitting arrangement according to the invention are discussed below. Further embodiments can result from the dependent claims, the description of the figures and the figures themselves.

According to one embodiment, it is provided that the stop surface is formed by a blocking lug which extends outward from the outside of the engaging section, the stop surface being formed on a side of the blocking lug facing away from the free end of the engaging section. The blocking nose therefore has the stop surface on its side facing away from the free end of the engagement section.

Instead of a projection in the form of the blocking nose, the stop surface can, for example, also be formed by a kind of recess in the outside of the engagement section or by a through opening in the engagement section, which engages with a projection at the upper edge of the striking plate opening when the door is off is forcibly raised outside. In this case too, in its engaged position, the swivel hook engages with its stop surface, which is formed by the recess or the passage opening in the engagement section, from an upper edge section of the striking plate opening from below, thereby preventing the lifting and sliding door from being pushed open even in its raised position.

As can be seen from the above illustrations, a type of abutment is provided on the outside of the engagement section, which serves to engage the upper edge section of the striking plate opening when a violent attempt is made to lift the door for opening purposes.

According to a further embodiment, the blocking nose on its side facing the free end of the engagement section can have a contour which tapers in a wedge shape in the direction of the free end of the engagement section. This can prevent the blocking lug from abutting or coming into contact with the upper edge section of the striking plate opening when the swivel hook is pivoted into the striking plate opening. Rather, the wedge-shaped tapering contour of the blocking nose in the direction of the free end of the engagement section creates a kind of threading aid by which the pivoting of the swivel hook into the striking plate opening is facilitated if it is not optimally aligned with the striking plate opening.

According to a further embodiment, the swivel hook can have a substantially U-shaped hook section, the engagement section of the swivel hook forming one half of the U-shaped hook section or of the "U".

According to yet another embodiment, the stop surface of the locking lug can be formed at the end of the engagement section opposite the free end of the engagement section, which in the case of a U-shaped hook section can mean that the stop surface of the locking lug lies approximately in the middle of the two flanges of the "U" connecting arc section is located.

In order not to allow the lifting and sliding door to be lifted from the outside by force, the striking plate can, according to a further embodiment have a recess on its rear side for receiving the free end of the engagement section. Characterized in that the free end of the engaging portion is received by the recess in question, the lift and slide door is secured against upward forces, making it even more difficult to pry open the fitting arrangement. In addition, an operator who closes the lift and slide door and swivels the swivel hook into the striking plate opening by actuating the actuating lever receives tactile feedback via the actuating lever when the free end of the engagement section is pulled into the recess in question when the door is lowered, so that the operator receives feedback that the door is now actually locked. As an additional advantage, this "latching" of the free end of the engagement section in the recess ensures a defined end position of the swivel hook in the engaged position, so that the actuating lever coupled to the swivel hook is also in a defined, usually exactly vertical position. This avoids an optically unsightly, slightly slanted operating lever when the door is locked.

In the following, the invention will now be described purely by way of example with reference to the drawings, in which:

Fig. 1

shows a fitting arrangement according to the invention with a swivel hook;

2 and 3

explain the interaction of the fitting arrangement according to the invention with a striking plate.

The following will first refer to the Fig. 1 the fitting arrangement 10 according to the invention explained as such before subsequently with reference to the 2 and 3 the interaction of the fitting arrangement 10 according to the invention with a striking plate 30 is discussed.

The Fig. 1 shows a view of a fitting arrangement 10 according to the invention, which comprises a swivel hook 12 which is articulated in a lock case 14. The lock case 14 can be fitted in a manner known per se into a recess which is formed, for example, in a door rebate of a lift and slide door (not shown). The swivel hook 12 is mounted in particular in the lock box 14 so as to be pivotable about a swivel axis A, whereby it is located in the Fig. 1 is in its engaged position, from which it can be pivoted clockwise into the lock box 14 by actuating the actuating lever of the lift and slide door, which corresponds to the disengaged position of the swivel hook 12.

In the illustrated embodiment, the swivel hook 12 has a hook section 16 which has an essentially U-shaped shape. The U-shaped hook section 16 thus forms in its interior a receiving area 18 which serves to receive a lower edge section of a striking plate opening, which will be discussed in more detail below.

The swivel hook 14 has an engagement section 20 which, starting from the free end 22 of the hook 12, extends along the same in a slightly convex manner with respect to its outer side 26 in the direction of the swivel axis A. The engagement section 20 forms approximately half of the U-shaped hook section 16. On that half of the hook section 16, which is formed by the convexly curved engagement section 20, a blocking nose 24 is formed according to the invention, which protrudes from the convexly curved outer side 26 of the engagement section 20 extends radially outward.

This blocking lug 24, which is formed on the outer side 26 of the engagement section 20, has a substantially fin-like or sawtooth-like shape, since it has a transverse extension that points in the direction of the free end 22 of the engagement section 20 decreases continuously, whereby the engagement section 20 receives a tapered contour 29 in the direction of its free end 22. In contrast, the blocking lug 24 on the side facing away from the free end 22 of the engagement section 20 has a recessed step 28, which forms a stop surface 27 oriented transversely to the outside 26 of the engagement section 20, which serves as an abutment, which will be discussed in more detail below.

Since, in the illustrated embodiment, the engagement section 20 of the swivel hook 12 essentially forms one half of the U-shaped hook section 16, the stop surface in the illustrated embodiment defines approximately the end of the same opposite the free end 22 of the engagement section 20, since the recessed step 28 is approximately in the middle of the arc section connecting the two legs of the U-shaped hook section 16.

The following will now refer to the 2 and 3 the interaction of the fitting arrangement 10 with a striking plate 30, which according to one embodiment can also be part of the fitting arrangement.

Again Fig. 2 can be removed, the striking plate 30, which can be attached to a door frame (not shown), has an opening 32. In this opening 32, the swivel hook 12 was pivoted from its disengaged position, in which it is located inside the lock box 12, simultaneously with the lowering of the lift and slide door on which the fitting arrangement 10 is mounted, due to a pivoting of the actuating lever of the door in the counterclockwise direction. In the engaged position, the swivel hook 12 thus engages with its slightly convex engagement section 20 through the strike plate opening 32 such that the engagement section 20 engages behind the lower edge section 34 of the strike plate opening 32 from above.

In this engaged position, the free end 22 of the engagement section 20 engages in a recess 38 formed on the rear of the striking plate 30, which is formed on the rear of the striking plate 30 below the opening 32. Since the striking plate 30 is symmetrical in order to prevent incorrect assembly, a corresponding recess 38 is formed above the opening 32 in the rear of the striking plate 30. Since the free end 22 of the engaging section 20 of the swivel hook 12 engages in the recess 38 in question below the striking plate opening 32, it can be prevented that a lift and slide door equipped with the fitting arrangement 10 according to the invention can be forcibly lifted.

Should this succeed despite expectations, as is the case in the Fig. 3 is shown, in which the lock box 14 relative to its position in the Fig. 2 has experienced a translation upwards, the recessed step 28 of the blocking nose 34 and in particular the stop surface 27 of the recessed step 28 comes into contact with the upper edge section 36 of the striking plate opening 32. The abutment surface 27 in question of the blocking lug 24 thus serves as an abutment for the swivel hook 12, which can prevent the lift-and-slide door in the Fig. 3 shown violently raised position can be postponed. Rather, the swivel hook 12 experiences a torque, counterclockwise when starting from that in the Fig. 3 position is violently attempted to raise the door and thus the lock case 12 further, whereby the locking hook 12 is wedged in or on the opening 32. For this purpose, the swivel hook 12 is dimensioned such that the distance between the free end 22 of the engaging section 20 and the side of the blocking lug 24 facing away from the free end of the engaging section 20 is greater than the clear width of the opening 32 of the striking plate 30 the free end 22 of the engagement portion 22 is urged against the lower edge portion 34 of the striking plate opening 22, if starting from the in Fig. 3 Attached position is attempted to raise the door and thus the lock box 14, which can reliably prevent the swivel hook 12 from disengaging from the striking plate opening 32.
