Technical Field

The present invention relates to a lock. The lock is designed in particular for insertion into a door leaf. It is particularly preferably a security lock.

Background

The lock concerned here has, in particular, a lock housing and a cover and is designed for insertion into a door leaf. Usually, a door handle or knob is connected on both sides of the door leaf via the tumblers of the lock. The bolt of the lock can be retracted by manipulating the door handle or knob. The lock of particular interest herein is a deadbolt-free safety lock, also known as a "classroom lock". This type of lock does not have a latch for closing the door. Rather, manipulation of the deadbolt is prevented so that the door cannot be opened. The driver is here divided and has driver halves which can be rotated independently of one another. With the aid of a knob or door handle on the door side, only one of the driver halves can be rotated. For example, an external door handle can be blocked in its normal position by manipulating a closing or ball lock cylinder. In this case, the toggle center disposed between the toggle halves is blocked. The driver halves associated with the outer door handle are connected to the blockable driver core. Thus, for example, unauthorized entry into a classroom during a school class can be prevented. In this case, there is always the possibility of escape from the interior, since the bolt can be pulled back from the interior via the door handle, since the driver half associated with the interior door handle is not connected to the blockable driver core. This ensures a safety function, i.e. a possibility of escape that always exists. The disadvantage here is that the connection of the driver halves to the driver core cannot withstand sufficient forces. The load moment of the lock is therefore absorbed only to a limited extent via the blocked door handle. Furthermore, it cannot be ensured that: the connection between the toggle halves and the toggle center is limited to the door outer side to be blocked and the toggle halves associated with the door inner side are not accidentally connected to the toggle center as well.

Disclosure of Invention

The object of the present invention is to provide a lock, in particular a safety lock, which is versatile in simple and low maintenance operation. In particular, it is an object of the invention to provide a lock, in particular a safety lock, in which the toggle halves can be blocked simply, safely and/or reliably. In particular, the blocking possibility of the toggle half relative to the other toggle half can be achieved simply, safely and/or reliably.

This object is achieved by the features of the invention. The following text has preferred developments of the subject matter of the invention.

The object is therefore achieved by a lock. The lock is in particular designed as a safety lock. The lock includes a bolt and a separate toggle member. The separated shifting piece comprises a first shifting piece half part and a second shifting piece half part. The two toggle halves are rotatable independently of each other about a common toggle axis and each configured for retracting the bolt. In particular, both toggle halves have corresponding latch arms. The latch arm is moved by rotating the toggle piece half. Two latch arms are in turn operatively connected to the latch and enable retraction of the latch.

If the lock is designed as a safety lock, at least one of the two tumbler halves, in particular exactly one tumbler half, is always rotatable. Thus, the bolt can be retracted by rotating one toggle half at all times. Typically, the toggle half via which the deadbolt can always be retracted is associated with the inside of the door. The door inner side here denotes the door side facing the space to be protected.

The other toggle half can be blocked or blockable. When the toggle piece half is blocked, the rotation of the toggle piece half for retracting the lock tongue is prevented. The blocking of the other toggle half can be carried out permanently, so that the bolt can always be retracted only by the one toggle half. Alternatively, blocking of the other toggle part half can be established and cancelled in the installed lock. The blocking can be established and/or canceled, for example, by closing the lock cylinder or the ball lock cylinder. The blocked and/or blockable toggle halves are typically associated with the outside of the door. The door outer side here denotes the side of the door facing away from the space to be protected.

Furthermore, according to the invention, the lock comprises a pressure piece. The pressure piece is configured to selectively block rotation of either the first toggle half or the second toggle half.

The pressing block can block the first toggle piece half part or the second toggle piece half part. Since the first toggle part half or the second toggle part half can be selectively blocked by the pressure piece, the blocking possibility can be switched from one toggle part half to the other toggle part half by means of the pressure piece. The problematic connection to the toggle center is eliminated. Preferably, the driver is formed without a driver core. By switching the blocking possibility via the pressure piece, a simple, safe and/or reliable switching can be ensured.

The lock comprises a lock housing. The pressure piece is arranged in the lock housing.

Preferably, the pressure piece is movable into a first blocking position and a second blocking position. The pressure piece is movable back and forth between first and second blocking positions. The pressure piece can be moved in particular within the lock housing from a first blocking position into a second blocking position.

The pressure piece can be moved in particular from the first blocking position into the second blocking position without opening the lock housing. In particular, the movability of the pressure piece can be provided before the lock is mounted. The movability of the pressure piece can be limited in particular to the time before the lock is installed.

In the first blocking position, the first toggle part half can be blocked by the pressure piece. In the second blocking position, the second toggle part half can be blocked by the pressure piece. Thus, for example, when the lock is used as a "classroom lock", it is possible to flexibly select: which side of the lock is located on the outside of the door.

In particular, in the first blocking position, the pressure piece is prevented from blocking the second toggle part half. In particular, in the second blocking position, the pressure piece is prevented from blocking the first toggle part half. In the respective blocking position, the blocking possibility of the pressure piece can therefore be limited to one toggle part half.

In order to selectively prevent a rotation of the first toggle part half or of the second toggle part half, the pressure piece can be pivotably arranged. In particular, the pressure piece can be pivoted about a pivot axis perpendicular to the toggle axis. By pivoting the pressure piece about its pivot axis, the pressure piece can be moved into the first blocking position and the second blocking position. By means of the pivotable pressure piece, it is particularly simple to set on the lock: the first toggle half and the second toggle half should be blocked.

Preferably, each of the toggle halves comprises a blocking arm. The pressure piece rests against the respective blocking arm in its respective blocking position. In the first blocking position, the pressure piece can rest against the blocking arm of the first toggle part half. In the second blocking position, the pressure piece can rest against the blocking arm of the second toggle part half.

By the blocking arm resting against the pressure piece, the rotary movement of the respective toggle half is blocked.

The housing of the lock can have a front side. On this front side, the locking tongue projects outwards. The front side is opposite to the back side. A cover is present in particular on the front side of the lock housing.

The two blocking arms preferably extend from the toggle member towards the rear side of the lock housing.

It is also preferably provided that the two blocking arms each have a blocking surface. The pressing block is attached to the blocking surface. In particular, the two blocking surfaces are each inclined such that the pressure pieces lie flat against one another. This ensures a planar, and thus non-point-like or non-linear load between the blocking surface of the blocking arm and the pressure piece. The slope of the blocking surface preferably corresponds to the slope of the pressure piece, depending on size and direction. In other words, a first angle between the blocking surface of the first toggle part half and the center plane of the lock and a second angle between a surface of the pressure piece facing the blocking surface in the first blocking position and the center plane of the lock are substantially the same. Thus, the first angle and the second angle can differ by less than 5 °, preferably less than 2 °, for example. A third angle between the blocking surface of the second toggle part half and the center plane of the lock and a fourth angle between the surface of the pressure piece facing the blocking surface in the second blocking position and the center plane of the lock are substantially identical. Thus, the third angle and the fourth angle can differ by less than 5 °, preferably less than 2 °, for example. In the case of a pivotable pressure piece, the blocking face can be inclined to the center plane of the lock.

It is furthermore preferably provided that the lock comprises a retaining element. The holding element is in particular designed as a holding pin. In the retaining position of the retaining element, the retaining element retains the pressure piece in its respective blocking position. If the holding element is in its holding position, the pressure piece is held or fixed by the holding element in the first or second blocking position. In the holding position of the holding element, the pressure piece is prevented from moving from the first blocking position into the second blocking position or from the second blocking position into the first blocking position.

Preferably, the holding element is movable between a holding position and a switching position. If the holding element is in the switching position, the pressure piece can be moved from one blocking position into the other blocking position, in particular pivoted into the other blocking position. Thus, the switching position of the holding element allows: the pressure piece is moved from the first blocking position into the second blocking position and from the second blocking position into the first blocking position. Preferably, the holding element is at least partially located in the lock housing in both the holding position and the switching position.

Thus, the retaining element is moved into its conversion position before the lock is installed in the door leaf. The pressure piece can thus be brought into the desired blocking position in order to block the first or second toggle part half. In particular, for this purpose, the lock is correspondingly tilted so that the pressure piece falls into one or the other blocking position on the basis of gravity. Subsequently, the holding element is again brought into the holding position. Whereby the pressure piece is fixed in its blocking position. Thus, it was determined that: from which door side the rotation of the toggle half can be blocked. It is thus determined from which door side the opening of the door can be prevented.

Preferably, it is provided that the direction of movement of the holding element for movement between the holding position and the switching position is oriented perpendicular to the direction of movement of the locking bolt and/or perpendicular to the driver axis. In particular, the retaining element can be moved upwards into the switching position and downwards into the retaining position in the normal installation position of the lock.

It is furthermore preferably provided that the lock comprises a retaining element spring which moves the retaining element into the retaining position. The holding element can be moved into the switching position against the spring force.

The holding element can be held in the holding position by a holding element spring. Thus, the holding element is prevented from being accidentally switched into the switching position.

The lock can comprise a guide means, in particular an elongated hole, by which the retaining means is guided. The holding mechanism can be guided in a movement from the switching position into the holding position.

As initially described, the lock preferably comprises a lock housing. Preferably, it is provided that the retaining element projects from the lock housing. In particular, the holding element can be moved manually without tools. In an alternative preferred embodiment, it is provided that the holding element is accessible from the outside via an opening in the lock housing. The holding element can be moved by means of a tool, for example.

The lock housing preferably has a front side as described. The lock housing has at least one further side, preferably a plurality of further sides. The other side can be configured as a rear side. The side of the lock housing can be located between the front side and the rear side as the further side. The holding element preferably projects from the lock housing on the other side or the opening for accessing the holding element is preferably located on the other side of the lock housing. The further side from which the retaining element projects or on which the opening for the retaining element is located is no longer accessible after the lock has been installed. As a result, the holding element can no longer be actuated after the lock has been installed in the door leaf. Accordingly, the pressure piece also remains in the set blocking position after the lock is installed.

Alternatively, the holding element can be accessed from the front side. In this case, the possibility of moving the holding element is limited to: the authorization aid is operated in advance or simultaneously. The blocking toggle piece half can therefore be switched in operation of the lock only for an authorized operator.

For example, the holding element can project from the lock housing on the rear side, or an opening for accessing the holding element can be located on the rear side of the lock housing, for example.

Of course, even if the holding element protrudes from the lock housing, an opening can be provided in the lock housing. The opening for the extension of the holding element and the opening for access to the inserted holding element are preferably each designed as an elongated hole in the lock housing. The elongated hole preferably extends in the direction of movement of the holding element, in particular perpendicularly to the direction of movement of the bolt and perpendicularly to the driver axis. The elongated hole can be used for guiding the holding element if the holding element protrudes from the lock housing.

The pressure piece is preferably movable into a blocking position and into an open position. The movability of the pressure piece into the blocking position and into the open position can preferably be provided in an installed lock. When the blocking position is set, movement of the pressure piece can be limited to movement between the blocking position and the open position.

In the blocking position, the press block blocks one of the two toggle part halves depending on the setting of the blocking position. In the open position, the pressure piece releases the blockable toggle half. In particular, in the open position, the pressure piece does not block either of the two toggle halves. In the open position, the door can be opened from both sides by means of a door handle.

For movement between the blocking position and the open position, the pressure piece is preferably moved linearly. This movement is preferably parallel to the movement of the bolt and/or perpendicular to the toggle axis. In the installed lock, the movement between the open position and the blocking position is preferably horizontal.

The lock can comprise a guide by means of which the pressure piece retains the blocking position when moving from the blocking position into the open position. In particular, the holding element can serve as a guide. In particular, the retaining element can hold the pressure piece in the set blocking position in both the open position and the blocking position by means of the length of the retaining element.

Particularly preferably, the lock comprises a slider. The pressing block can be connected with the sliding block.

The pressure piece can be movably, in particular pivotably, received on the slide. The pressure piece is thus moved relative to the slide into the first blocking position and/or into the second blocking position.

Furthermore, the pressure piece can move together with the slide. The slide can be moved in particular parallel to the bolt movement and/or linearly perpendicular to the driver axis. By moving the slide, the pressure piece is moved back and forth between its blocking position and its open position.

Accordingly, the slider also has a blocking position and an open position.

The pressure piece is movable between an open position and a blocking position via the slide. The slider can be connected with the briquetting for the slider drives the briquetting during the slider motion. The slide can be connected to the pressure piece in a form-fitting and/or force-fitting manner.

The movement of the pressure piece between the blocking position and the open position is preferably performed by means of a closing cylinder or a ball cylinder which can be inserted into the lock. Alternatively, the lock can comprise the closed cylinder or a ball cylinder. The movement of the pressure piece between the blocking position and the open position takes place in particular via a slide. By turning the closure cylinder or the ball cylinder, the slider can be moved linearly. The slide block drives the pressing block.

The slide can comprise an active surface for acting with a closing cylinder or a ball cylinder. The slider is linearly movable by turning a closure cylinder or a ball cylinder that can be inserted into the lock.

The lock can have a locking device which is raised when the lock cylinder or the ball lock cylinder is closed by rotation, thereby releasing the movement of the slide. The slide is held in this end position in a form-fitting manner, in particular in its respective end position, by a spring-loaded locking device. The locking device can thus be first moved by closing the lock cylinder or the ball lock cylinder, thereby releasing the movement of the slide. The slide is then moved by closing the lock cylinder or the ball lock cylinder.

The described pivot axis of the pressure piece can be an imaginary pivot axis and need not be formed, for example, by a shaft or a bolt. The pivot axis can therefore also be produced by surfaces rolling on each other. When the pressure piece pivots, the pressure piece can undergo a slight linear movement in addition to its pivoting or rotational movement.

Preferably, the slide and the pressure piece bear against one another at the contact surface. Here, a plurality of mutually separated contact surfaces can also be formed.

Preferably, the force acting on the pressure piece when an attempt is made to rotate the blocked toggle part half can be transmitted to the slide. In the blocking position, the force transmitted to the pressure piece can be transmitted to the lock housing via the sliding block. The force can be transmitted to the lock housing, for example, via a guide of the slide.

During the pivoting movement of the pressure piece, the two contact surfaces roll on one another. The sliding block and/or the pressure piece are preferably formed in a curved manner at the contact surface in order to support the pivoting movement.

In a preferred embodiment, the compact has at least one shoulder. Preferably two shoulders are provided. The pressure piece is placed on the slide by means of at least one shoulder, preferably two shoulders. If two shoulders are provided, the slide and the pressure piece each have two contact surfaces. The press block is held on the shoulder by the slide block.

The slider preferably has two lateral U-shaped receptacles. The two shoulders of the pressure piece are located in the two lateral U-shaped receptacles.

It is also preferably provided that the pressure piece has a downwardly projecting bulge between its two shoulders. The protuberance is preferably located in a U-shaped receptacle in the center of the slider.

It is furthermore preferably provided that the slide and the pressure piece are connected to one another via a pin. The pin preferably extends parallel to the toggle axis. The pin is loosely located in the forming hole in the press block or slide. The forming hole differs from the usual cylindrical shape with a circular cross section, so that the pivoting movement of the pressure piece is not blocked by the shape of the forming hole. The pin is therefore firmly arranged on one of the two elements, i.e. the pressure piece or the slide, and is loosely inserted in the shaped hole of the respective other element, so that the pin does not block the pivoting movement.

Furthermore, the lock, in particular the lock housing, has a stop on at least one side of the pressure piece. The stop limits the movement, in particular the pivoting movement, of the pressure piece, so that the pressure piece does not move too far outward, in particular pivot too far, in the respective direction.

As already described, the lock is preferably designed as a "classroom lock" and is preferably designed here with a double-sided set of door handles, however with separate door handle pins. The door handle pins therefore each extend only into one of the toggle part halves, rather than through the entire toggle part. In this way, the two door handles can be actuated independently of one another with different functions. The escape possibilities from the inside are readily available via the inner door handle. This ensures a safety function, i.e. the possibility of escaping from the protected space that is always present. The blocking of the outer door handle is maintained even after the door is opened from the inside. The lock core or the spherical lock core is closed through rotation, so that the blocking of the outer door handle can be cancelled from the inside and the outside through moving the sliding block and the pressing block. The door can also be opened via an external door handle in the event of unblocking.

In particular, classroom locks do not have a latch. The slide is actuated by means of a closing cylinder or a ball cylinder.

The bolt of the lock is in particular designed as a locking bolt. The locking function is preferably produced by a locking bolt. For this purpose, in the closed position of the door, the locking bolt is locked via the control bolt against an external actuating back pressure.

The door side, on which the door handle or knob can be blocked, can only be selected before installation, since the retaining element is on the rear side of the lock housing. This provides an anti-actuation protection which prevents a change of the door side with a blockable door handle in the installed state.

The bolt is preferably configured as a swing bolt so that the bolt can be adjusted according to the direction of the door. Likewise, the control bolt can preferably be designed as a swiveling bolt, which can be adjusted according to the direction of the door. In particular, the lock can thus be used in a simple manner for left-hand outward opening, right-hand outward opening, left-hand inward opening and/or right-hand inward opening.

In order to block the slide in its respective end position, i.e. in the blocking position or the open position, the slide can be fixed in a force-fitting manner by means of a spring or, as already described, in a form-fitting manner by means of a locking device.

The lock can preferably comprise a double lock cylinder for operating the slider, so that the slider can be moved from both sides of the door via a key or knob. In this case, the blocking can be switched from the inside via the knob at any time and by anyone, i.e. the slide is moved into the blocking position. The key holder can perform the entry blocking from the outside, and thus can enter the room only after being released by the key holder (e.g., teacher or supervisor), for example. Entry barriers are of interest for protecting personal items, for example in schools during rest. When the slider is in the blocking position, emergency opening can only be performed from the outside by the key holder.

Detailed Description

In the following, the lock 1 is described in detail with the aid of fig. 1 to 7. Herein, reference is made to all drawings unless otherwise indicated.

The lock 1 comprises a lock housing 2 and a cover 3. The lock housing 2 has a front side 4 and a rear side 5 opposite the front side 4. The cover 3 is on the front side 4. The lock 1 is pushed into the door leaf during assembly, with the rear side 5 facing forward.

Furthermore, the lock 1 comprises a bolt 6 and a control bolt 7. The locking tongue 6 and the control locking tongue 7 project outwards through the cover 3 on the front side 4. In the closed position of the door, the control latch 7 is pressed in, thereby blocking the actuation of the latch 6, i.e. the external pressing in of the latch 6.

The lock also includes a toggle member 8. The toggle 8 is divided into two parts, which can be seen in particular in fig. 2, 4 and 5. By dividing the toggle 8 into two parts, the toggle 8 comprises a first toggle half 10 and a second toggle half 11. The two toggle halves 10, 11 can be rotated independently of one another about a common toggle axis 9.

Each of the toggle halves 10, 11 includes a latch arm 12 and a blocking arm 13, respectively. Two latch arms 12 are connected to the latch 6. By rotating the respective toggle half 10, 11, the associated bolt arm 12 is pivoted and in the process pulls the bolt 6 linearly inward along the bolt axis 36. The bolt axis 36 is perpendicular to the toggle axis 9.

The lock 1 further comprises a pivotable pressure piece 20 and a slide 21. The pressure piece 20 is pivotably accommodated in the slide 21 or on the slide 21. Here, the pressure piece 20 can be pivoted about a pivot axis 22. The pivot axis 22 extends perpendicular to the toggle axis 9 and parallel to the bolt axis 36.

The pressure piece 20 is movable back and forth between a first blocking position and a second blocking position. In fig. 1, 2 and 4, the pressure piece 20 is in the first blocking position. In this case, the pressure piece 20 bears against the stop arm 13 of the first toggle part half 10, and thus prevents a rotational movement of the first toggle part half 10.

Fig. 5 shows that the pressure piece can be pivoted about the pivot axis 22 so as to be in its second blocking position. In the second blocking position according to fig. 5, the pressure piece 20 blocks the second toggle part half 11 via the blocking arm 13.

In order to fix the pressure piece 20 in its respective blocking position, a retaining element 23 is provided. The holding element 23 is designed here as a pin which projects out of the lock housing 2 on the rear side 5. The holding element 23 is accommodated in the opening 25 so as to be linearly movable. The opening 25 is configured as an elongated hole. The holding element 23 is thus movable back and forth between the switching position and the holding position. The direction of movement of the holding element 23 extends perpendicular to the bolt axis 36, perpendicular to the pivot axis 22 and perpendicular to the toggle axis 9.

In its upper position, the holding element 23 is in the switching position. This is shown in fig. 3. In this switching position, the retaining element 23 releases the pivoting movement of the pressure piece 20. By tilting the entire lock 1 accordingly, the pressure piece 20 falls under gravity loading into the or the other blocking position. Subsequently, the holding element 23 is moved into its holding position. The holding position is shown, for example, in fig. 1, 2, 4 and 5.

Fig. 1 shows a purely schematic illustration of a retaining element spring 24, which moves the retaining element 23 into its retaining position.

Furthermore, the figures show: the slide 21 and, together with the slide 21, the pressure piece 20 are also linearly movable between the blocking position and the open position. Fig. 1 and 2 show the slide 21 and the pressure piece 20 in the blocking position. Fig. 3 shows the slide 21 and the pressure piece 20 in the open position. In the blocking position, one of the two toggle halves 10, 11 is blocked in its rotational movement via the pressure piece 20. In the open position, the pressure piece 20 is moved toward the rear side 5 and does not block either of the two toggle halves 10, 11.

In fig. 1 and 3, the holding element 23 is shown as a guide for the pressure piece 20. The retaining element 23 projects into the lock housing 2, so that the retaining element 23 holds the pressure piece 20 in the first blocking position in the open position and in the blocking position. Accordingly, the holding element 23 holds the pressure piece 20 in the second blocking position in the open position and in the blocking position in fig. 5.

The displacement of the slide 21 takes place in the embodiment shown via a lock cylinder, not shown, which can be inserted into the lock housing 2 below the slide 21. In order to prevent manipulation of the slide 21, a locking device 35 is provided here. When the key cylinder is rotated, the locking device 35 is raised, thereby enabling the slider 21 to move.

fig. 4 and 5 show the pressure piece 20 in its first blocking position (fig. 4) for blocking the first toggle part half 10 and in its second blocking position (fig. 5) for blocking the second toggle part half 11, it being seen in both figures that the blocking arms 13 each have a blocking surface 26 on their side facing the pressure piece 20, the blocking surfaces 26 being inclined at an angle α relative to a plane which is preferably defined in such a way that said plane is parallel to the pivot axis 22 and to the toggle axis 9, the angle α preferably being 2 ° to 30 °, in particular 5 ° to 15 °, a flat contact between the toggle arm 13 and the pressure piece 20 being achieved by the inclination of the blocking surfaces.

Fig. 6 shows an exploded view of the slide 21 and the pressure piece 20 in a position separated from each other. Fig. 7 shows a side view of the pressure piece 20 and the slide 21 in the assembled position. Two figures 6, 7 show: the slide 21 comprises a central U-shaped receptacle 27 and two lateral U-shaped receptacles 28. The compact 20 has two shoulders 30 and a ridge 29 located between the two shoulders 30. By means of two shoulders 30, the pressure piece 20 is supported in two lateral U-shaped receptacles 28. The bulge 29 projects into the central U-shaped receptacle 27.

In the region of the central U-shaped receptacle 27 or in the region of the bulge 29, the pressure piece 20 and the slide 21 are connected via a pin 31 (see, for example, fig. 1 to 3). The pin 31 extends substantially parallel to the toggle axis 9. In particular, fig. 6 shows: a forming hole 32 is provided in the compact 20. The shaped openings 32 are configured here as elongated openings. The pin 31 is inserted in the shaped hole 32. The geometry of the shaped openings 32 ensures that: the pin does not block the pivotal movement of the pressure piece 20.

Fig. 7 furthermore shows a contact surface 33 on the shoulder 30 or in the lateral U-shaped receptacle 28. The contact surface 33 can be formed in a curved manner on both sides or on one side, i.e. on the pressure piece 20, on the slide 21 or on both elements, in order to facilitate the pivoting movement of the pressure piece 20.

Furthermore, fig. 6, for example, shows that the pressure piece 20 can have a ramp 34 which is designed to slide the pressure piece 20 under the respective blocking arm 13 when moving from the open position into the blocking position.
