Description

The invention relates to a connecting rod fitting for a door or window sash with the features of the preamble of claim 1. In addition, the invention relates to a door or window lock with the features of the independent claim. Finally, the invention relates to a door or window arrangement according to the further independent claim.

Driving rod fittings of the type mentioned are known from the prior art, for example. In the form of one of the Applicant under the name "UNI-JET" sold fitting. This fitting has a faceplate, a drive rod and a locking pin fastened to the drive rod and guided in an elongated hole in the faceplate. If the rebate clearance is large, the locking plate attached to the door or window frame pulls out the locking pin during locking, for example via inlet chamfers. The drive rod, which is slightly spaced apart from the faceplate, deforms elastically. This allows for gap clearance compensation, albeit limited to small gap clearance tolerances. Because the dimensioning of the drive rod is predetermined due to the forces to be transmitted, a high force is required to pull out the locking pin (high frictional forces). This can lead to high operating forces for the user on the handle, for example a rotary handle.

Another espagnolette is off EP 1 293 627 B1 known. In this drive rod fitting, the locking pin is coupled to the drive rod via an elastic guide element and is guided in a passage relative to the drive rod. If the guide element is actuated by a control pin, the guide element and the locking pin are pivoted away from the drive rod. The disadvantage is that radial forces acting on the locking pin due to sealing pressure or wind pressure cannot be adequately absorbed by the guide element. In addition, the locking pin needs sufficient play in the passage of the drive rod to the To allow pivoting movement. This reduces the stability.

The invention is based on the object of using simple structural means to provide a stable espagnolette fitting in which only small frictional forces occur even when large rebate clearance tolerances are compensated.

The invention solves this problem by a drive rod fitting with the features of claim 1. According to this, the drive rod fitting is characterized in that a spring element is arranged on the side of the faceplate facing away from the drive rod (faceplate outer side), which is supported on the faceplate and the Locking pin applied with a force which forces the locking pin into an extended position relative to the faceplate or would like to bring it.

In other words, the force applied by the spring element to the locking pin is directed away from the drive rod (direction of force points away from the drive rod). The locking pin is issued or pushed out of the faceplate or the espagnolette fitting by the spring element. The spring element acts between the faceplate and the locking pin.

The proposed embodiment has the advantage that the spring force to be applied to the locking pin can be adjusted by dimensioning the spring element, regardless of the stability requirements for the drive rod. Due to the spring element, the locking pin is outward, ie pretensioned away from the connecting rod and possibly relocated. This favors the introduction of the locking pin into a locking plate, since the spring element is largely relaxed when the locking pin moves into or in the locking plate. In this way, large rebate clearance tolerances can be compensated for with low frictional forces, since displacement forces are reduced by the pretensioning by means of the spring element, which in turn leads to low operating forces on a handle, for example on a rotary handle. The spring element thus supports a displacement of the locking pin along its longitudinal direction. The locking pin can be displaced along its longitudinal direction, since the drive rod is elastically deformable, for example by the force applied by the spring element to the locking pin.

The drive rod can be displaceably coupled to the faceplate, for example by means of slots formed on the drive rod or faceplate and, for example, mushroom-shaped pins arranged on the other component, which each engage in one of the slots.

The locking pin is attached to the connecting rod, for example riveted. The locking pin is guided in particular in the elongated hole formed on the faceplate. The locking pin can have a base section, with which the locking pin is fastened to the drive rod, and an (eccentric) head section rotatable relative to the base section, with which the locking pin is adjusted for adjustment purposes can be. The locking pin can optionally be designed as a mushroom head pin.

The connecting rod fitting in question can be actuated by means of a handle, for example a rotary handle, and / or a motor drive, which each act on the connecting rod. For example, by turning a rotary handle, the drive rod is displaced along its longitudinal direction relative to the faceplate.

The espagnolette fitting can form a tilt and turn fitting or a part thereof. The tilt and turn fitting can be a design often referred to as a "central lock", in which all components can be actuated by means of a handle.

The spring element can be, for example, a compression spring element. The faceplate can also be referred to as a faceplate rail.

The spring element can expediently be coupled to the locking pin, so that the spring element is displaced together with the locking pin when the locking pin is displaced along the elongated hole in the faceplate. If the locking pin is moved by moving the drive rod, the spring element moves with it. As a result, the locking pin and the spring element are firmly coupled to one another and therefore in engagement with one another.

In the context of a preferred embodiment, the spring element can be designed such that this Oblong hole predominantly (e.g. at least 50 percent) or completely covered. A flat spring element is thus provided which largely protects the drive rod fitting, in particular the internal components of the drive rod fitting (for example drive rod) from environmental influences. This significantly reduces the risk of foreign bodies or moisture getting in.

The width of the spring element (extension transversely to the longitudinal direction of the elongated hole) can correspond to at least the width of the elongated hole or be wider, in particular slightly wider, than the width of the elongated hole.

The elongated hole can be covered predominantly (for example at least 50%) or completely by the spring element at least when the connecting rod fitting is in the rotational position. In the rotational position of the door or window sash, the locking pin can be aligned approximately centrally along the elongated hole, in particular in the area of the middle 10 percent of the length of the elongated hole. As a result, the elongated hole is covered when the risk of environmental influences is greatest, namely when the espagnolette is in the rotary position, for example when the door or window sash is to be pivoted.

In concrete terms, the spring element can be designed as a leaf spring. Thus, a stable spring element is created with simple structural means, which, for example. can be adjusted in its spring constant by changing the material thickness and can also at least partially cover the elongated hole.

The spring element can expediently be formed from metal, in particular from steel, or from plastic. With a spring element made of metal or steel, an elastic and stable spring element can be created, whereby high spring constants can also be achieved. The spring element made of metal or steel can be designed as a pure leaf spring, for example as a spring plate with a passage for coupling the locking pin. In the case of an embodiment made of plastic, an inexpensive spring element can be achieved, with which an advantageous friction pairing (metal-plastic) can be realized for the faceplate. The spring element made of plastic can have a leaf spring section and an adjoining sleeve-shaped section via which the spring element can be coupled to the locking pin.

In the context of a preferred embodiment, a projection or shoulder can be formed on the side of the faceplate facing the drive rod, which (at least) when the drive rod fitting is in the rotational position, interacts with a bend or elevation formed on the drive rod, so that the Locking pin is in a retracted position relative to the faceplate. The locking pin can thus be retracted against the force of the spring element by the interaction of these components. Thus, the locking pin is in the rotary position has a reduced overhang relative to the faceplate, so that the risk of collisions with the frame or frame-side components is reduced. The projection or shoulder is located in particular on the edge of the elongated hole formed in the faceplate. As already explained above, in the rotational position of the door or window sash, the locking pin is aligned approximately centrally along the elongated hole, in particular in the area of the middle 10 percent of the length of the elongated hole.

Advantageously, the bend or elevation can extend along the drive rod in such a way that the locking pin is also in a retracted position relative to the faceplate when the drive rod fitting is in the tilted position. The risk of collision can thus be reduced by the small protrusion of the locking pin relative to the faceplate, even in the tilted position. In the tilted position, the locking pin can be located at a first end of the elongated hole, in particular at the end of the elongated hole facing away from the locked position (e.g. on the handle side of the sash when the espagnolette fitting is installed, often the lower end in the direction of gravity).

According to a preferred embodiment, the drive rod can be designed in such a way that the bend or elevation of the drive rod comes out of contact with the projection or shoulder of the faceplate when the drive rod fitting is moved from the rotational position (locking pin along the elongated hole approximately in the middle; see above) into the locking position will. As a result, as a result of the force of the spring element, the locking pin is in the extended or deployed position relative to the faceplate, so that engagement with a locking plate can take place. In the closed position, the locking pin can be located at a second end of the elongated hole, in particular at the end of the elongated hole facing away from the tilt position (e.g. on the handle side of the sash when the espagnolette fitting is installed, often the upper end in the direction of gravity).

In other words, the drive rod can have a first drive rod section (fastening section) in the area in which the locking pin is attached to the drive rod, to which a cranked section (bend or elevation) adjoins at least one end, preferably at both ends, which can come into contact with the faceplate or with the projection or shoulder of the faceplate. The first drive rod section (fastening section) is set back relative to the faceplate, in particular parallel.

The object mentioned at the beginning is also achieved by a door or window lock with the features of the independent claim, reference being made to the relevant statements of claim 1 with regard to the advantages that can be achieved therewith. The strike plate can also be referred to as a strike plate. The door or window lock has hardware components mounted on the sash side (espagnolette fitting) and hardware components mounted on the frame side (striker plate).

The closing plate can have one or more mounting holes for fastening the closing plate to a door or window frame, for example by screwing. The locking plate can have a groove for receiving the locking pin. Behind-grip sections for engaging behind a locking pin or mushroom-head pin can be formed on the groove.

In addition, the object mentioned at the beginning is also achieved by a door or window arrangement with the features of the further independent claim, reference being made to the relevant statements of claim 1 with regard to the advantages.

According to this, the door or window arrangement has a frame (door or window frame), a sash mounted pivotably on the frame (door or window sash) and a door or window lock as described above. The closing plate is arranged on the frame and the espagnolette is arranged on the sash. Closing plate and connecting rod fitting can be attached to the frame or sash, for example by screwing.

The wing can be pivoted into a closed position and an open position relative to the frame. The locking plate can be arranged and fastened on the narrow side of the frame and the espagnolette fitting on the narrow side of the sash, so that the locking pin and the locking plate are in Closed position of the wing can be brought into engagement with one another.

In particular in tight rebate clearance situations, the closing plate can be positioned on the frame and / or its height dimensioned in such a way that the closing plate presses on the spring element, so that the locking pin is retracted or retracted as a result. This reduces the protrusion of the locking pin relative to the faceplate. In this way, the locking pin can also be locked on the locking plate or move into the locking position if the locking pin protrudes too much relative to the faceplate for this purpose.

Figure 1 shows a section of a connecting rod fitting for a door or window sash, wherein the connecting rod fitting is provided with the reference numeral 10 as a whole.

The drive rod fitting 10 has a faceplate or faceplate 12 and a drive rod 14 which is longitudinally displaceable on the faceplate 12 (cf. Figure 2 ) with the forend 12 is slidably coupled. In addition, a locking pin 16 is provided, which is fastened to the drive rod 14, for example by riveting, and protrudes through an elongated hole 18 formed in the faceplate 12 (cf. Figure 3 ff.). The locking pin 16 can be guided in the elongated hole 18.

The espagnolette 10 can be attached to a door or window sash by means of the faceplate 12. For this purpose, engagement sections 20 for engaging a wing-side groove and / or fastening passages 22 for screwing the faceplate 12 can be formed on the faceplate 12.

Also shown is a closing plate 13 (cf. Figure 4 f.), which can be attached to a frame of a door or window arrangement (not shown). The locking plate 13 has mounting holes 15 and a groove 17 for receiving the locking pin 16. On the groove 17, rear grip sections 19 for engaging behind a locking pin or a mushroom head pin can be formed.

By moving the drive rod 14 along the faceplate 12, the drive rod fitting 10 can, depending on the position of the drive rod 14 and locking pin 16, be in a locked position relative to the faceplate 12 (see FIG Figure 6 ; Closing plate 13 not shown), a rotary position (see Figure 4 ) and brought into a tilted position (not shown).

In the closed position, the locking pin 16 is in particular at a first end, here, for example, on FIG Figure 6 right end of the elongated hole 18 (cf. Figure 6 ). In In the rotational position, the locking pin 16 is aligned essentially centrally along the elongated hole 18 (cf. Figure 4 ). In the tilted position, the locking pin 16 is in particular at the second end of the elongated hole 18, that is to say here, for example, on the end of the elongated hole 18 facing away from the locked position (this would be in FIG Figure 4 the left end of the elongated hole 18).

On the side of the faceplate 12 facing the drive rod 14 (faceplate rear side), a projection or shoulder 24 is formed on the elongated hole 18 (cf. Figure 4 ff.). The projection or shoulder 24 can be designed in such a way that the faceplate 12 has a greater material thickness in the area of the elongated hole 18 than in sections of the faceplate 12 adjacent to the elongated hole 18.

The drive rod 14 has a first drive rod section 26 which is set back relative to the faceplate 12, in particular parallel (cf. Figure 4 ff.). The locking pin 16 is fastened to the drive rod 14 in the first drive rod section 26. At one end, optionally at both ends, of the first drive rod section 26, a bend or elevation 28 is arranged, which can be designed as a cranked section 28 of the drive rod 14.

By displacing the drive rod 14 along its longitudinal direction relative to the faceplate 12, the cranked section 28 can come into contact with the faceplate 12 or with the projection or shoulder 24 of the faceplate 12. In the latter In this case, the drive rod 14 can shift away from the faceplate 12 (the drive rod 14 is spaced apart from the faceplate 12 due to the interaction of the bend or elevation 28 with the projection or shoulder 24), as a result of which the locking pin 16 is retracted or retracted relative to the faceplate 12.

A spring element 30 is arranged on the side of the faceplate 12 facing away from the drive rod 14 (cf. Figure 1 ff.). The spring element 30 is supported on the faceplate 12 and acts on the locking pin 16 with a force which attempts to bring the locking pin 16 into an extended position relative to the faceplate 12 (direction of force of the spring element 30 directed away from the drive rod 14). The spring element 30 can, for example, be designed as a compression spring element.

The spring element 30 is coupled to the locking pin 16, so that the spring element 30 is displaced together with the locking pin 16 when the locking pin 16 is displaced along the elongated hole 18.

The spring element 30 is designed in such a way that it predominantly or completely covers the elongated hole 18. In the exemplary embodiment, the spring element 30 is designed, for example, in such a way that it completely covers the elongated hole 18 when the drive rod fitting 10 is in the rotational position (cf. Figure 4 ). Other dimensions are also conceivable.

The spring element 30 is designed in particular as a leaf spring. It is conceivable that the spring element 30 is made of metal, in particular steel (not shown), or - as in the exemplary embodiment - is made of plastic. The spring element 30 made of plastic has a leaf spring section 32 and an adjoining sleeve-shaped section 34 via which the spring element 30 is coupled to the locking pin 16 (cf. Figure 4 ff.).

The locking pin 16 has a base section 36 with which the locking pin 16 is fastened to the drive rod 14, and an (eccentric) head section 38 which can be rotated relative to the base section 36 and with which the locking pin 16 can be adjusted for adjustment purposes. The locking pin 16 can thus be designed overall as a mushroom pin.

The invention works as follows:
As explained above, the projection or shoulder 24 is formed on the side of the faceplate 12 facing the drive rod 14. This works at least when the connecting rod fitting 10 is in the rotary position (cf. Figure 4 ; Locking pin 16 aligned approximately in the middle along the elongated hole 18), together with the bend or elevation 28 formed on the drive rod 14. As a result, the drive rod 14 is displaced away from the faceplate 12, as a result of which the locking pin 16 is retracted or retracted against the force of the spring element 30 relative to the faceplate 12.

The locking pin 16 is then in a retracted position relative to the faceplate 12 (cf. Figure 4 ).

The bend or elevation 28 extends along the drive rod 14 such that the locking pin 16 is also in the tilted position of the drive rod fitting 10 in a retracted position relative to the faceplate 12 (tilted position not shown). If the connecting rod fitting 10 is based on the rotary position (cf. Figure 4 ) brought into the tilted position, the locking pin 16 and the spring element 30 move by shifting the drive rod 14 in this configuration to the second end of the elongated hole 18 (in Figure 4 to the left).

The drive rod 14 is designed in such a way that the bend or elevation 28 of the drive rod 14 comes out of contact with the projection or shoulder 24 of the faceplate 12 when the drive rod fitting 10 is moved from the rotational position (cf. Figure 4 ) is brought into the closed position (cf. Figure 5 ). The bend or elevation 28 (cranked section 28 of the drive rod 14) then approaches the faceplate 12 or comes into contact with it, the spring element 30 relaxing and bringing the locking pin 16 into the extended or parked position (cf. Figure 5 ). Locking pin 16 and spring element 30 move further in this configuration by shifting drive rod 14 until drive rod fitting 10 reaches the closed position (cf. Figure 6 ).

the Figures 7 and 8 show a close rebate clearance situation, ie a situation in which a connecting rod fitting 10 mounted on a door or window sash (not shown) and a closing plate 13 mounted on a door or window frame (not shown) have a comparatively small distance from one another.

As an alternative or in addition to the configuration described above with a projection or shoulder 24 on the faceplate 12 and a bend or elevation 28 on the drive rod 14, the following configuration is conceivable for retracting or pushing back the locking pin 16.

Particularly in tight rebate clearance situations, the closing plate 13 can be positioned on the frame and / or its height dimensioned in such a way that the closing plate 13, e.g. Coupling with the spring element 30 is thereby retracted or retracted relative to the faceplate 12 (cf. Figure 7 ). This reduces the protrusion of the locking pin 16 relative to the faceplate 12, so that the locking pin 16 can be moved into the groove 19 of the locking plate 13 to reach the locked position (cf. Figure 8 ).
