Definitions

• the invention relates to a locking system for a door or a window and to a door or a window with such a locking system.
• handles designed as door handles or window handles to operate a door or window lock.
• These handles are arranged on the two large surfaces of the door or window and are connected to one another via a polygonal pin, particularly a square pin.
• the handles are arranged on the polygonal pin in a rotationally fixed manner, so that a synchronous adjustment movement occurs when one of the handles is operated.
• the polygonal pin engages a lock nut of a mortise lock, which is inserted into a corresponding lock receptacle in a door leaf or window leaf.
• the lock nut has a polygonal receptacle with which the polygonal pin engages.
• a locking system according to the preamble of claim 1 is, for example, made of US 2021/238882 A1 known.
• the invention is based on the object of creating an alternative locking system by means of which a door or window can be locked in its closed position from one side using a polygonal pin. Furthermore, the invention is based on the object of providing a window and a door with such a locking system.
• a locking system for a door or window comprising a first handle, a second handle, a polygonal pin with a base pin, and a locking slide.
• the polygonal pin engages the first handle at a first end in a rotationally fixed manner and the second handle at a second end opposite the first end in the axial direction of the polygonal pin.
• the base pin extends continuously between the two handles.
• the locking slide is mounted on the base pin so that it can move in the axial direction of the polygonal pin.
• the polygonal pin has an engagement element for engaging a lock nut of a lock.
• the engagement element is rotatably mounted relative to the base pin and can be switched by means of the locking slide between a holding state, in which the engagement element is arranged rotationally fixed relative to the base pin, and a release state. In the release state, the engagement element can be rotated relative to the base pin, in particular about a longitudinal axis of the polygonal pin.
• the core idea of the invention is that the engagement element can be switched between the held state and the released state by means of the polygonal pin.
• the engagement element In the held state, the engagement element is rotated together with the base pin when one of the two handles is operated, so that the corresponding lock can be operated via the lock nut.
• the released state when one of the handles is operated, only the base pin is rotated relative to the lock or the lock nut, while the engagement element remains unrotated, so that the lock nut or the lock is not operated.
• the latter corresponds to the locked position of the locking system, in which the door or window cannot be opened even if one of the handles is operated.
• the base pin can be made of one or more parts.
• the polygonal pin for example, is at least partially designed as a square pin.
• the locking system comprises an emergency release slide that can be moved in the axial direction of the polygonal pin.
• the emergency release slide is arranged on the side of the polygonal pin facing away from the locking slide and can be moved between a basic position and an emergency position.
• the emergency release slide In the basic position, the emergency release slide is disengaged from the engagement element, i.e., spaced from it or has no connection to it.
• the engagement element can be rotated relative to the base pin, for example.
• the emergency release slide can engage the engagement element in such a way that the engagement element is held in a rotationally fixed position relative to the base pin. If the emergency release slide is in the emergency position, a rotational movement of the base element can be transmitted to the engagement element. Actuation of one of the handles can thus lead to the actuation of the lock follower or the corresponding lock, allowing the door or window to be opened.
• the emergency release slide can be mounted on the base pin so that it can be moved.
• the base section comprises at least one guide track on which the locking slide or the emergency release slide is displaceably mounted.
• the base section can have exactly two guideways, wherein the locking slide is slidably mounted on a first of the guideways and the emergency release slide is slidably mounted on the second guideway.
• the locking slide and/or the emergency release slide are/is T-shaped.
• the at least one guideway can be delimited laterally by side walls which extend away from a base body of the base pin, in particular in extension of the side walls of the base body.
• the side walls each have a recess.
• Arms of the T-shaped locking slide or the T-shaped emergency release slide can be arranged in the recesses.
• the recesses can be aligned with each other in the transverse direction of the polygonal pin.
• the recesses are, for example, of a length such that the locking slide or the emergency release slide can be moved in the axial direction of the polygonal pin.
• the length of the recess in the axial direction of the polygonal pin is therefore, for example, greater than the extension of the arms of the T-shaped locking slide or the T-shaped emergency release slide in the axial direction of the polygonal pin.
• the relative movement range of the locking slide or the emergency release slide to the base pin can be limited.
• the locking slide is displaced in the holding state in the direction of the engagement element in such a way that the engagement element is arranged, in particular partially, in a groove-like receptacle of the engagement element in such a way that the holding element transmits a rotational movement of the base pin to the engagement element.
• the groove-like receptacle of the engagement element is aligned with the at least one guide track, in particular with the guide tracks, when the handles are in an unactuated state.
• the base pin, the engagement element and/or the locking slide are designed as separate components.
• the locking slide and/or the emergency release slide can or can (each) have a longitudinal extension, i.e. an extension in the axial direction of the polygonal pin, which is at most half, in particular less than half, of the longitudinal extension of the base pin.
• the locking slide engages with its end facing away from the engagement element in a shaft of the first handle, on which an actuating element connected, in particular fixedly, to the locking slide is arranged.
• the actuating element can, for example, be screwed to the locking slide.
• the actuating element is manually accessible, for example, when the locking system is mounted on a door or window.
• the actuating element can pass through a shaft of the first handle in the radial direction.
• the locking system comprises a folding element pivotally mounted on the emergency release slide. This allows the folding element to pivot between an inserted position and an installed position.
• the folding element can be pivotable about a rotation axis extending in the transverse direction of the polygonal pin.
• the folding element in particular a longitudinal axis of the folding element, is aligned horizontally in the inserted position, whereas the folding element is aligned vertically in the assembled position.
• the slider, together with the folding element, in the inserted position, in which the longitudinal axis of the slider and the longitudinal axis of the folding element are aligned parallel can be easily pushed through the lock nut to install the actuating device, whereby tilting or wedging of the polygonal pin during assembly of the actuating device can be ruled out.
• the vertical alignment of the folding element in the assembled position in which the locking system is fully mounted on the door or window and in which the longitudinal axis of the folding element is arranged orthogonally to the longitudinal axis of the emergency release slide, allows easy access to the emergency release slide via the folding element.
• the locking system comprises a spring that preloads the emergency release slide in a home position. Moving the emergency release slide from the home position to the emergency position thus requires a force acting counter to the spring force, particularly in the direction of the engagement element. When the external force is removed, the spring automatically returns the emergency release slide to the home position.
• the second handle in which the emergency release slide is arranged, comprises at least one tool opening.
• the second handle can have exactly one tool opening or exactly two tool openings.
• a tool for moving the emergency release slide, in particular from the basic position to the emergency position, i.e. for moving the emergency release slide in the axial direction of the polygonal pin, can be inserted through the tool opening.
• the emergency release slide is moved in the direction of the locking slide, for example by means of the tool, i.e. when the emergency release slide is pressed, a rotational movement of the base pin is transmitted via the emergency release slide to the engagement element so that the lock nut can be actuated.
• the tool opening can be formed on an underside of the handle, in particular in the form of an elongated slot, or on a side of the handle facing away from the first handle, in particular in the form of a round recess.
• the tool opening can be arranged so that a tool can be inserted through the tool opening in such a way that the tool rests directly against the emergency release slide.
• the tool opening is arranged, for example, in such a way that a tool can be inserted through the tool opening in such a way that the tool rests against the folding element or engages in a recess of the folding element, which in turn transmits an adjustment movement to the emergency release slide.
• the base pin comprises two polygonal sections, in particular one polygonal section at each end, and a bearing section connecting the two polygonal sections to one another.
• the base pin can be designed in one or two parts.
• one of the polygonal sections and the bearing section is designed as one component and the other polygonal section forms a separate component.
