Description

[0001] The invention relates to a locking device for a door or window of a building with the features of the preamble of claim 1.

[0002] Doors in kindergartens or similar facilities must be designed so that children cannot open them on their own. This prevents children from leaving the kindergarten unsupervised. In practice, this is achieved by mounting the door handle high enough that children cannot reach it.

[0003] A corresponding locking device is known from EP 2 466 044 B1. This patent provides a first lock with locking elements and a second lock with a lever-operated lock cylinder, which is located above the first lock. The second lock is fitted with a door handle and is connected to the first lock via a connecting rod. The height of the door handle of the second lock is positioned so that supervisors can operate it to open the door. However, children cannot reach the door handle, which is mounted at this height. This ensures that the door can be opened by supervisors, but children cannot open it unsupervised.

[0004] German patent application DE 10 2014 113 503 A1 shows a locking device with a main lock and an auxiliary lock mounted above the main lock. The two locks are connected by an operating rod, so that the operation of one lock can be transferred to the other lock.

[0005] Document DE 20 2005 000 939 U1 shows a locking device with a main lock and two auxiliary locks. The auxiliary locks are controlled by a pull rod connected to the main lock in such a way that they can be operated together with the main lock, i.e., moved into the locked or unlocked position.

[0006] The invention is based on the objective of creating a locking device that offers high functional reliability, is cost-effective to manufacture, and is suitable for use in kindergartens or similar institutions. In particular, the locking device should enable the doors or windows to close tightly.

[0007] This problem is solved according to the invention by a locking device with the features of claim 1.

[0008] According to the invention, a locking device for a door or window of a building is proposed, comprising a first lock which has at least one locking element, wherein the at least one locking element comprises a locking bolt and / or a locking latch or a latch bolt, and a second lock which has a lever-operated lock follower and wherein the second lock is arranged above the first lock in the installed state, and a connecting rod or a connecting slide to transmit an opening movement and / or a closing movement of the second lock to the first lock or vice versa.The essential feature is that the first lock has a sliding plate slidably mounted in a first lock housing, which interacts with the at least one locking element to actuate it between an open position and a locked position, and that the second lock has a sliding plate slidably mounted in a second lock housing and at least one locking element, wherein the second sliding plate interacts with the at least one locking element to actuate or switch it between an open position and a locked position, and wherein the at least one locking element of the second lock comprises a lock bolt and / or a lock latch or a latch bolt.

[0009] Advantageously, the locking mechanism features two locks arranged one above the other and spaced apart, each with at least one bolt. This creates a multi-point locking system on the door to be secured, ensuring it is securely locked in the closed position. This significantly reduces leaks around the door, such as those that can occur with a single lock due to warping of the door leaf. The improved sealing also offers advantages in terms of the building's air conditioning costs. Furthermore, the inclusion of a sliding plate ensures reliable operation of the bolts. The sliding plate allows for more than one bolt per lock, for example, so that the first lock and the second lock can each have two bolts.

[0010] The term "open position" refers to an unlocked position of the door. In the open position, the locking elements are retracted into the lock housing, or, in the case of a tilt latch or cross latch, for example, they are soft-engaged, meaning they are not rigidly locked.

[0011] The term "locked position" refers to a locked position of the door. In the locked position, the locking elements are extended into the lock housing, or, in the case of a tilt-and-turn or cross-latch lock, for example, engaged, i.e., locked against tilting.

[0012] Preferably, a sliding plate is understood to be a plate-shaped component within a lock housing. The sliding plate is mounted so as to be linearly displaceable within the lock housing and can serve to transmit forces and / or movements from a drive to a locking element. By moving the sliding plate, locking elements of the lock can be actuated between an open position and a locked position.

[0013] Preferably, the term "bolt elements" refers to typical lock bolt elements such as a latch or bolt. The bolt can be a solid component, for example, made of metal. In the open position, the bolt is fully retracted into the lock housing. In the locked position, the bolt protrudes from the lock housing and engages in a strike plate or a strike plate on the door frame or another door leaf to lock the door.

[0014] Preferably, the term "lock trap" refers to a snap trap, a tilting trap, or a cross trap.

[0015] Preferably, a latch bolt is understood to be a lock latch that can be switched to a rigid position or extended from the lock housing into a bolt position in order to fulfill the function of a lock bolt.

[0016] Advantageously, the first lock and / or the second lock can each be designed as a mortise lock. The lock assembly can be easily mounted on a door that has the corresponding recesses or pockets for the two locks.

[0017] In a preferred embodiment, the connecting rod or connecting slide can connect the slide plate of the first lock to the slide plate of the second lock. The connecting rod or connecting slide can, for example, be made of round or flat material. The connecting rod or connecting slide can transmit tensile and compressive forces between the first lock and the second lock.

[0018] Preferably, the first lock and the second lock may each have a faceplate that extends continuously from the first lock to the second lock and holds both locks. Preferably, the faceplate supports the two locks and covers them from the front. Thus, the lock mechanism is both visually concealed and mechanically protected against dirt and / or damage by the faceplate.

[0019] In particular, the connecting rod or connecting slide may be guided parallel to the faceplate and / or mounted on the faceplate so as to be linearly movable. In one embodiment, the slide plate of the second lock may have a downwardly directed extension that reaches through an opening in the lock housing and is coupled to the connecting rod or connecting slide, in particular that the extension is formed integrally with the slide plate. For example, the extension may be positively connected to the connecting rod or connecting slide. For example, the connecting rod or connecting slide may have a recess into which a correspondingly shaped pin of the extension engages, or vice versa.

[0020] For example, it may be provided that the sliding plate of the first lock has an upwardly directed connection that is coupled to the connecting rod or connecting slide.

[0021] Advantageously, the sliding plate for the first lock and the sliding plate for the second lock can be identical. This reduces the number of parts and lowers manufacturing costs. Preferably, "identical sliding plate" refers to the shape of the sliding plate within the lock housing. In particular, the sliding plate can be designed with or without the downward-facing extension for coupling the connecting rod or connecting slide and is still considered an identical sliding plate, provided that the sliding plate is otherwise identical.

[0022] In particular, it may be provided that the second lock has a split lock nut, especially to set one of the panic functions Panic E, or Panic B, or Panic C.

[0023] For example, the first lock may be designed with a split spindle, particularly to enable one of the panic functions: Panic E, Panic B, or Panic C. To reliably prevent, for instance, children in a kindergarten from opening the door unsupervised, the inside of the split spindle of the first lock may be permanently disengaged. Typically, the inside of the door, at a height of normal door operation (around 100 to 110 cm), is fitted with a doorknob that does not allow the door lock to be operated. Children can grasp this knob but cannot unlock the door. By permanently disengaging the inside of the spindle, a lever handle can also be installed on the inside of the door at a normal height, but this handle will not unlock the lock mechanism because the corresponding spindle is permanently disengaged.

[0024] The locking mechanism can be designed as a self-locking mechanism, in particular as a panic lock. For this purpose, the first lock and / or the second lock can, for example, have an auxiliary latch which, together with a spring assembly, securely locks the door by extending the locking bolts once it has entered the closed position. To enable safe passage through and opening of the door in an emergency or panic situation, the locking mechanism is designed to be panic-proof and can, for example, implement panic functions E, B, or C.

[0025] With panic function E, the door can be unlocked by pressing the door handle on the inside. This means the locking bolts retract into the lock housing, allowing the door to be opened quickly and easily by pressing the handle. In particular, no key is required. From the outside, the door only has a knob and is locked by default. The door can only be opened from the outside with a key. Panic function E enables a rapid escape, as the door can be opened from the inside at any time without delay in an emergency. This is combined with a high level of security, as the door is well protected from the outside and can only be opened with the correct key.

[0026] The panic function B, like all panic locks, allows the door to be opened from the inside at any time without a key, simply by pressing the door handle. The outside door handle is normally disengaged. This means that even if the door is locked from the inside, it cannot be opened from the outside simply by pressing the handle. The outside handle can be permanently engaged using the key or lock cylinder. Only when the door is locked again does the outside handle lose its ability to open the door. This allows the door to be accessed from both sides. Therefore, a key is required to open the door from the outside.

[0027] With panic function C, the door can also be opened from the inside at any time by pressing the door handle. From the outside, the door is always locked and can only be opened with a key. The outer handle is in its neutral position and cannot be operated. The door can only be opened from the outside with a key. The lock is therefore permanently engaged. This means the outer handle is in its neutral position. If the door lock is unlocked with a key, thus moving the outer handle out of its neutral position, the door can then be opened. However, to remove the key, the door must be returned to its original position. This is why it is called a forced locking function. This allows for high security requirements to be met, as access from the outside is only possible with a key.

[0028] The panic function can be selected, for example, during lock installation by setting the panic function using a switching element and / or a screw on the lock cylinder. Alternatively, an electronic coupling function can be provided to couple the lock cylinder electronically. For example, the first lock and / or the second lock may have an electric drive device for electrically coupling or uncoupling the respective lock cylinder, or a part of the respective lock cylinder, or half of the respective lock cylinder.

[0029] To implement a self-locking panic lock, it may be provided that the first lock and / or the second lock has an auxiliary latch to control the self-locking of the locking device.

[0030] In an advantageous embodiment, the locking device or locks of the locking device can be modularly expandable. For example, the locks can be optionally equipped with one or two locking elements. Likewise, the locks can be enhanced with a motorized drive. Thus, the first lock and / or the second lock can be provided with an electric drive motor that interacts with the respective sliding plate to actuate the locking elements between the open and locked positions. This enables remote-controlled motorized operation of the locking device.

[0031] One application of the locking device according to the invention is intended for kindergartens or similar facilities. The locking device according to the invention enables the door to be securely locked and effectively prevents children from opening the door unsupervised. In an emergency, the door can still be opened from the inside at any time. Because the locking device according to the invention has a multi-point locking mechanism, i.e., more than one locking element, a particularly reliable and secure locking of the door in the closed position is achieved. This also allows the use of particularly tight door seals to ensure a high level of airtightness.

[0032] To meet insulation requirements.

[0033] The figures show exemplary embodiments of the invention, which are described below. These include: Fig. 1 a schematic application example of the locking device according to the invention on an inside side of the door; Fig. 2 the outside of the door; Fig. 3 a schematic side view of the locking device according to the invention; Fig. 4 a front view of the locking device according to the invention; Fig. 5 a schematic view of the upper lock of the locking device; Fig. 6 a schematic view of the lower or central lock of the locking device

[0034] The embodiments shown in the figures are exemplary and should not be understood as limiting. Components with the same function are identified by the same reference symbols. It is clear to a person skilled in the art that, within the scope of protection defined by the claims, the features shown can be modified or combined without departing from the scope of the invention.

[0035] Fig. 1Figure 1 shows a door 1 in a building. The door 1 has a door frame 11 in which a door leaf 12 is rotatably mounted. The lock device 2 according to the invention is integrated into the door leaf 12. The lock device 2 comprises a first lock 3 and a second lock 4 mounted at a distance above the first lock 3. The two locks 3 and 4 are connected to each other by a connecting rod 22 and a connecting slide 22, respectively. The connecting slide 22 transmits an opening and closing movement between the two locks 3 and 4. The upper lock 3 has an inside door handle 15. The inside door handle 15 is located on the inside of the door at a height of approximately 1.50 m to 1.60 m above the floor and allows the door 1 to be opened at any time by actuating the door handle.

[0036] The first lock 3 has two locking elements: a bolt 37 and a latch 35. The second lock 4 has a latch 44 as its locking element. Optionally, the second lock 4 could also be equipped with a bolt for increased security. Both locks 3 and 4 have a receptacle for a cylinder lock. The first lock 3 and / or the second lock 4 can also have a reversible mechanism, allowing the first lock 3 and / or the second lock 4 to be opened using a cylinder lock.

[0037] In the Figure 2The exterior of door 1 is shown. The two hinges 13 and 14 are visible from the outside, which pivot the door leaf 12 to the door frame 11. An exterior door handle 16 is installed on the outside of the door at the first lock 3. The door handle 16 is positioned at the usual operating height, which is between 1 m and 1.10 m. Optionally, the second lock 4 can also be fitted with an exterior door handle. However, this is not mandatory, as the lock mechanism 2 can be operated with the single exterior door handle 16. Both the first lock 3 and the second lock 4 can be operated via a cylinder lock.

[0038] In the Figures 3 and 4 The lock device 2 according to the invention is shown enlarged. Figure 3 This shows a side view of the locking device 2 according to the invention. Figure 4 The front view, i.e., the mullion 21, is shown. As in the Fig. 3 and Fig. 4As can be seen, the faceplate 21 runs continuously from the first lock 3 to the second lock 4. The first lock 3 has a lock housing 31, which is mechanically connected to the faceplate. Similarly, the second lock 4 has a lock housing 41, which is mechanically connected to the faceplate 21. The connecting rod 22, or connecting slide 22, is located on the back of the faceplate. The connecting slide 22 connects the first lock 3 to the second lock 4.

[0039] The connecting slide 22 allows an opening or closing movement to be transmitted from the second lock 4 to the first lock 3 or vice versa. The locking elements of the locking device according to the invention comprise a latch 44 arranged in the second lock 4, as well as a latch 35 and a bolt 37 arranged in the first lock 3. Furthermore, the first lock 3 comprises an auxiliary latch 36, which serves to automatically lock the locking device 2 when the door is moved into the closed position. As in Fig. 4 As can be seen, the locking elements, namely the bolt 37, the latch 35 and the catch 44, engage through recesses in the faceplate 21. The auxiliary catch 36 also engages through a recess in the faceplate 21.

[0040] The locking bolt 37 has a release pin 371. This makes it possible to use the locking device 2 according to the invention even with double-leaf doors. A double-leaf door typically has an active leaf and a fixed leaf. The locking device 2 according to the invention is arranged in the active leaf. A bolt locking device is provided in the fixed leaf, which has bolt slides or latch slides for unlocking the active leaf locks of the active leaf. The release pin 371 can be actuated via the bolt slide of the fixed leaf, whereupon the locking bolt 37 can be pushed back into the lock housing 31 of the first lock 3. Via the in Fig. 6The sliding plate 33 shown is moved by the guidance of the bolt 37 in the inclined guide groove 34 and by this movement also the other bolt elements, i.e. the lock latch 35 and by means of the connecting rod 22 also the lock latch 44 of the second lock 4 are retracted and the active leaf is thus unlocked.

[0041] The schematic structure of the second lock 4 is shown in the Fig. 5 shown. For the sake of clarity, the castle ceiling was removed there. Inside the castle housing 41, as shown in the Fig. 5As can be seen, the vertically movable sliding plate 43 is arranged. The sliding plate 43 has a projection 431 at its lower end, which protrudes from the lock housing 41. The projection 431 is connected to the connecting rod 22 or the connecting slide 22 via a pin connection. This causes a movement of the sliding plate 43 to be transmitted to the connecting slide 22 or connecting rod 22 and vice versa.

[0042] A split lock cylinder 42 is rotatably mounted in the lock housing 41. The split lock cylinder 42 has two halves, an inner half and an outer half. Different panic functions, such as panic function B, panic function C, or panic function E, can be set via these halves.

[0043] The Fig. 6Figure 1 shows a schematic view of the first lock 3. In the first lock 3, the slide plate 33 is also mounted so as to be vertically displaceable. The slide plate 33 has a guide groove 34 over which the lock bolt 37 can move between its open and locked positions. On its upper surface, the slide plate 33 has a pin to actuate the lock latch 35 between the locked and open positions. In the upper part of the lock housing 31, the slide plate 33 has a connection 331 that extends through an opening in the lock housing 31 and is connected to the connecting rod 22 or the connecting slide 23. This transmits movement of the connecting rod 22 or the connecting slide 23 to the slide plate 33, and vice versa.

[0044] Furthermore, the first lock 3 has a spring drive that interacts with the sliding plate, which is located in the Fig. 6(Not shown.) The spring drive is compressed in the open position and actuates the sliding plate 33 into the locked position by spring force. This locking movement is controlled by the auxiliary latch 36 in such a way that, when the door is moved into the closed position, and after the door has securely reached this position, the locking device 2 automatically locks the locking elements, in particular the locking bolt 37.

[0045] Furthermore, the first lock 3 has a lock follower 32 rotatably mounted in the lock housing 31. This lock follower 32 is also designed as a split lock follower with an inner half and an outer half. The inner half of the lock follower 32 is permanently engaged in a free-running position. An external door handle 16 can be connected to the outer half of the lock follower 32. By permanently engaging the free-running position of the inner side of the lock follower 32, it is effectively prevented that a door handle mounted on the inside of the lock follower 32 can operate the first lock 3 or the locking device 2. This ensures the safe operation of the locking device 2 according to the invention in kindergartens and similar facilities. Reference symbol list
