Definitions

• the invention relates to a misuse protection for an espagnolette fitting of a driving rod guided displaceably along a window or door leaf in at least two switching positions, consisting of a locking lever which is pivotally mounted in the fitting receiving groove and which extends near the inner edge of the flap and almost parallel to it Has stop arm which engages through the faceplate of the espagnolette fitting in the direction of the groove base and acts as a blocking arm in any open position of the window or door leaf with one of at least two locking cutouts arranged one behind the other in the connecting rod with the connecting rod in operative connection.
• Such mishandling devices prevent that when the window sash is open, i. That is, in its tilt or swivel opening position, the drive rod fitting can be changed over, thereby avoiding undesired unlocking of the tilt or swivel bearings, which would otherwise lead to a more or less dangerous falling out of the wing and, furthermore, would affect the wing flap. Protection against incorrect operation does not require any significant space in the rebate space between the sash and frame, so that due to the simple contour, no reworking has to be carried out on the sash frame.
• a device for automatic misuse protection is disclosed in DE 3345 814 C2, which has a V-shaped locking lever which can be pivoted in the vicinity of the inner edge of the flap and parallel to its axis and which has a stop arm which faces the flap and extends in the longitudinal direction thereof and a locking arm facing the faceplate is provided with at least one locking pin and on the faceplate with a bearing opening penetrating the locking arm attached bearing pin, on the head of which a compression spring is supported, which tries to press the locking lever with its locking arm into a locking position approximated to the faceplate, in which the locking pin engages in one of several locking holes arranged one behind the other in the adjusting rod.
• the bearing pin is releasably attached to the faceplate.
• a disadvantage of the known prior art is that more than two and different components are used in order to achieve a solution to prevent incorrect operation.
• assembly is only possible via additional tool intervention.
• the spring element itself is designed in a ring shape, is supported on the outside of the faceplate with a predetermined circumferential section, while on the opposite circumferential section it carries the locking member which has a guide opening in the faceplate in the region of the support section and behind it also a slot of the drive rod assigned to the latching engagements be upheld.
• the invention is based on the object to provide a misuse protection of the type mentioned, which is inexpensive to manufacture with a structurally simple design and can be mounted on the espagnolette fitting without special assembly effort.
• the locking lever rests on the wall of the fitting receiving groove and is thus U-shaped in the area of the fitting receiving groove, in order to keep as much space as possible open for further functional components and, on the other hand, to provide secure support in the event of incorrect operation of the connecting rod fitting guarantee.
• a further preferred development is characterized in that the locking lever has a leg toward the open end, which surrounds the outer edge of the faceplate in a C-shape and thus secures the misuse protection to the connecting rod fitting. Due to the simple and inexpensive manufacture, the misuse protection can be clipped onto the faceplate of the connecting rod fitting with little effort, so that the misuse protection in the faceplate is held in the vertical direction of the fitting receiving groove by the C-shaped design.
• a guide part is arranged below the faceplate and within the U-shaped area of the locking lever.
• the outer shape of the guide part is the shape of the locking lever, d. i.e., adapted to the inner wall of the locking lever and the wall of the fitting receiving groove against which the outer wall of the locking lever rests, offers the necessary hold in the event of a possible incorrect operation in order to counteract the force of the incorrect operation accordingly, so that the locking lever bends in the area of the Fitting record groove can thus be excluded.
• the locking lever in terms of the nature of the material, the material thickness or the shape in such a way that the guide part can be dispensed with if necessary.
• Decisive for the design of the misuse protection is also the size of the load, which affects the misuse protection in the event of incorrect operation.
• the guide member is preferably made of a plastic material or a die-cast material.
• the drive rod of the drive rod fitting which is held in the guide part for guidance in both the horizontal and vertical directions, can also be transferred to its switching positions with particularly little friction due to the special choice of material.
• the guide part is not only form-fitting by leaning against the inner wall of the locking lever but also non-positively by a recess Inclusion of the locking arm is included in the locking lever. Due to the non-positive connection of the guide part to the locking lever via the recess, the guide part is held in the longitudinal direction of the fitting receiving groove by the lateral walls. It is particularly important that the recess from the groove base of the fitting receiving groove is designed to run at an acute angle in the direction of receiving the drive rod, so that the spring action of the locking arm that merges with the stop arm from the top edge from the faceplate has sufficient space for the spring action. At the same time, however, it is also important to control the locking arm with the stop arm in the event of incorrect operation in the longitudinal direction of the fitting receiving groove in a controlled manner over the length of the locking arm and to give it a corresponding stop.
• the locking arm of the locking lever near the groove base, starting from the outermost edge of the fitting receiving groove, angled in the direction of the longitudinal central axis of the connecting rod fitting up to the upper edge of the faceplate and thus finally extends to the recess of the guide part, which, as already mentioned, is at an acute angle runs, leans.
• This not only facilitates the interaction of the stop arm, which acts as a locking arm in the fitting receiving groove, with the actuating stop seated on the fixed frame or on the frame itself, but also results in a particularly favorable spring characteristic.
• the guide part is held vertically by frictional engagement and horizontally due to the side walls of the guide part by positive locking on the locking lever.
• the faceplate immediately next to the central longitudinal axis of the connecting rod fitting has an opening on both sides and the connecting rod has a cutout.
• the arrangement of the opening and the cut-out on both sides allow the left and right usability of the incorrect operation protection, the cut-out of the connecting rod being the Pivotal movement of the stop arm is limited by the boundary edge located closest to the inner edge of the wing flap. Due to the rectangular shape, the opening and the cut-out cut also give hold when force is applied along the fitting receiving groove due to incorrect operation, for example caused by further rotation of the actuating element in the tilted or pivoted open position, but also prevents the undesired shifting in the longitudinal direction of the fitting receiving groove, for example Assembly.
• a functional reliability of the incorrect operation safeguard is also favored by the fact that the angled shape supports the stop arm in pretension against a boundary edge of the locking cutout of the drive rod which is located to the longitudinal central axis of the fitting receiving groove.
• the prerequisite is that the locking lever is made of a resilient material, for example a molded plastic part, but is preferably made of a spring steel strip. The pretensioning of the locking arm always ensures that the locking arm is in the locked position when the drive rod fitting is in the tilted or opened position.
• each fitting part to be inserted into a fitting receiving groove e.g. the drive rod and the faceplate are individually manually inserted into the groove, aligned accordingly and then immediately screwed to fix the fitting in this aligned position.
• This repeating installation sequence for each fitting part namely inserting, aligning and screwing, leads to high work and time expenditure and complicates the automation of the fitting part fitting.

• a fitting part in particular the faceplate, is provided with at least one protruding projection on both sides facing the groove side walls. Attack this Finally holding elements in the fitting receiving groove, a longitudinal displacement of the fitting is no longer possible. As a result, the fitting parts are held in the fitting receiving groove with the aid of the holding elements.
