Definitions

  • the present invention relates to a door lock which has an improved sequence control and preferably an inductive energy transfer.
  • Building doors used for security in particular escape doors or fire protection doors, are usually provided with security locks in which the door closers automatically close the door after the door has been passed, so that, for example, in the event of a fire, the fire cannot spread into other rooms.
  • security locks must allow keyless actuation from the inside in order to allow people to leave a room or building in any case.
  • the security locks built into escape doors or fire protection doors often have a mechanism that differs from the conventional latch-and-bolt mechanism with an automatically extending latch bolt or locks with an automatically extending bolt, which are known per se according to the prior art (so-called self-locking locks) .
  • DE 36 31 118 C2 describes, for example, a safety lock with a bolt, a key-operated tumbler that locks the bolt in both its retracted and extended position, and an auxiliary latch which, when the door closes, is to be pressed in against the spring action by the latch head that protrudes on the faceplate the bolt guard locking cancels.
  • This lock therefore offers the advantage of a fundamentally secure locking of the fire door after a panic actuation.
  • auxiliary latch protrudes with its latch head from the faceplate of the lock when the door is in the open position and can therefore easily be manipulated either accidentally or intentionally in order to deploy the latch bolt or automatic bolt.
  • the door can hit the door frame or the strike plate present there when it is closed with the latch bolt, which can lead to corresponding damage or even to the inability of the lock to function.
  • the actual closed position of the door is often overcome in order to place it on the door frame and thus create unauthorized access from both sides. This is particularly disadvantageous when it is not just an escape door, but a fire door, the function of which is then no longer guaranteed.
  • Electromechanical door locks have been installed in building doors for security purposes, as these are purely mechanical Locks offer advantages. Electromechanical door locks can in principle receive their power supply on the one hand via a power supply through wiring from the frame through the door leaf to the lock or on the other hand they can be operated with one or more batteries.
  • the disadvantage of the wired variant is that the installation effort is very high. Cables must be laid in the wall, a cable transition must be made between the frame and the door leaf and the door leaf must be exposed for the cable to the lock. In particular, the cable transition is prone to failure. Wired locks are also more susceptible to manipulation.
  • Battery-operated locks have the disadvantage that the battery life is limited and the batteries therefore have to be replaced regularly. Due to the installation space, larger batteries with a higher capacity cannot be used in locks. The possible status monitoring and feedback are often kept as low as possible in order to increase the battery life. Although there is often a battery status indicator (warning that the battery should be replaced), they are usually used in larger objects such as Hotels have their batteries replaced at regular intervals, although they are not yet empty, in order to keep the effort of the technical staff as low as possible. The performance of batteries in door locks when used in exterior doors also decreases due to low outside temperatures in winter. Batteries must also be disposed of properly.
  • the transmitting and receiving sides should preferably be adjustable in order to obtain a transfer position that is as close as possible to one another.
  • the transmitter side is designed to be horizontally adjustable and the receiver side vertically.
  • the disadvantage is the adjustability on the lock side in that the corresponding installation space for the receiver and the actuating device in the lock, in addition to the conventional lock mechanism with latch and bolt, is very small and therefore complex and filigree. Due to the lack of installation space, the receiver side can only be designed very small. As a result, the power transfer is to be regarded as low and it takes a longer period of time to transfer the necessary energy. This can lead to functional problems when using the lock in practice.
  • U.S. 5,469,723 A describes a lock comprising a housing with an inside and an outside; an axis running through the housing from the inside to the outside.
  • Main bolt with a bolt section and a locking section, wherein the main bolt is slidable into and out of the housing.
  • Double acting actuating mechanism coupled to the main pin by the axle, the axle having a first pin for actuating the actuating mechanism and a second pin for actuating the actuating mechanism, the first pin and the second pin sliding the main pin into and out of the housing .
  • a combination hub which is arranged in the housing, the combination hub releasing the locking means when a combination key is inserted into the combination hub.
  • the present invention is based on the object of providing a door lock in which the sequence control is improved so that the latch bolt does not extend when the control latch is actuated with the door open.
  • Another aim of the present invention is to provide a door lock with inductive energy transmission that is independent of a wired or battery-connected power supply.
  • a locking system with the door lock according to the invention is to be provided.
  • the door lock (1) according to the invention and the locking system according to the invention have the advantage that the sequence control for the latch bolt (107) has been optimized so that intentional or unintentional manipulation of the control latch (125) is effectively prevented so that the original functions of escape doors or fire doors are guaranteed.
  • the optimized sequence control for the latch bolt (107) means that a conventional bolt is no longer necessary in the door lock (1) according to the invention, which simplifies the construction.
  • a secure and, at the same time, low-cost energy supply for the preferably electromechanical door lock (1) is advantageously created.
  • the free space in the door lock created by the bolt that is no longer necessary can, on the one hand, accommodate an inductive energy supply with a larger receiving unit, and thus faster charging of the lock-side energy storage device can be implemented. Larger energy storage elements, for example larger capacitors or also accumulators, can also be used.
  • an energy supply with a conventional battery can be implemented in a simple manner at the same time, if no power connection for inductive energy transmission is available or cannot be created on the frame side.
  • the entire control electronics, including the transmitter and receiver module can be accommodated in this area in a compact and protected manner.
  • the present invention relates to a door lock (1) which has a lock case (103), a forend (105) connected to the lock case (103), a latch bolt (107) that is spring-tensioned out of the lock case (103), a two-part Follower (109) with spring-loaded, adjustable follower coupling (111) and a control latch (125).
  • a door lock (1) which has a lock case (103), a forend (105) connected to the lock case (103), a latch bolt (107) that is spring-tensioned out of the lock case (103), a two-part Follower (109) with spring-loaded, adjustable follower coupling (111) and a control latch (125).
  • the door lock (1) is characterized in that the control latch (125) is in operative connection with the latch bolt (107) via a spring-loaded locking slide (127), so that basically four positions (I, II, III, IV) of latch bolts (107) and tax trap (125).
  • the latch bolt (107) In a first position (I) the latch bolt (107) is pretensioned by a first amount (M1) out of the lock case (103) and the control latch (125) is completely extended out of the lock case (103).
  • the locking slide (127) is received with its upper end (127a) in engagement (107a) of the latch bolt (107) and locks it.
  • the lower end (127b) of the locking slide (127) rests on a cam (125a) of the control latch (125).
  • This first position (I) describes an open door in which the latch bolt (107) is pretensioned out of the lock case (103) and protrudes by the amount (M1) over the faceplate (105) (cf. Fig. 1 , Fig. 2 ).
  • the control latch (125) is fully extended and holds the locking slide (127) with a cam (125a) at its end in a position in which it is received in the engagement (107a) of the latch bolt (107).
  • the locking slide (127) locks the latch bolt (107) and prevents it from being extended further to a dimension greater than the first dimension (M1).
  • the first dimension (M1) is 9.5 mm to 13 mm, in particular 11 mm.
  • the first position (I) thus describes the normal state of the door lock (1) when the door is open.
  • the latch bolt (107) In a second position (II), the latch bolt (107) is pretensioned out of the lock case (103) when the control latch (125) is partially or completely pressed into the lock case (103).
  • the locking slide (127) is received with its upper end (127a) in the engagement (107a) of the latch bolt (107) and locks it. At the same time, it is blocked by the bias of the latch bolt (107), while the lower end (127b) is free in an adjusting curve (125b) of the control latch (125).
  • This second position (II) describes the case that the door is open, as in the first position (I), but the control latch (125) is consciously or unconsciously actuated, that is, is pressed into the lock case (103) (cf. . Fig. 3 ).
  • pressing in a control latch or auxiliary latch causes the latch bolt or the (automatic) bolt to extend automatically.
  • the latch bolt (107) does not automatically extend because the spring-loaded latch bolt (107) engages the locking slide (127) with its upper end (127a) due to the pretension of the spring. holds, that is, blocks or clamps, so that the locking slide (127) cannot come into the release position for the latch bolt (107) according to its spring loading. Latch bolt (107) and locking slide (127) block each other in the second position (II) and thus hold each other in position.
  • This third position (III) describes the conscious or intentional closing of the door.
  • the door is open, as shown in the first position (I).
  • the latch bolt (107) and the control latch (125) over the strike plate (7) and are pressed into the lock case (103).

  • the latch bolt (107) In a fourth position (IV) the latch bolt (107) is biased by a second amount (M2) out of the lock case (103) and locked by a latch lock (129), while at the same time the control latch (125) is partially or completely in the lock case (103) is pressed in (cf. Fig. 5 ).
  • the locking slide (127) no longer locks the latch bolt (107) with its upper end (127a) and rests with its lower end (127b) in the cam (125b) of the control latch (125).
  • This fourth position (IV) follows the third position (III) directly in the sequence control according to the invention. Since the door is now closed, the control latch (125) sits on the strike plate (7) and remains pressed into the lock case (103), whereby the locking slide (127) remains in the release position. After the release by the locking slide (127) moved into the release position, the latch bolt (107) can now fully extend out of the lock case (103) due to its prestress. The latch bolt (107) then protrudes by the second dimension (M2) over the faceplate (105) and engages in the corresponding opening of the strike plate (7). The second dimension (M2) is 15 mm to 25 mm, in particular 20 mm. In this way the latch bolt (107) assumes its closed position, the presence of a conventional bolt is no longer necessary. The fourth position (IV) thus describes the normal state of the door lock (1) when the door is closed.

  • a handle (handle) connected to the nut (109) is operated in the usual way, so that the Latch bolt (107) is fully retracted into the lock case (103) and the door can be opened.
  • the control latch (125) previously seated on the strike plate (7) extends completely out of the lock case (103) due to the spring load.
  • the lower end (127b) of the locking slide (127) is guided on the adjusting cam (125b) of the control latch (125) and the cam (125a) runs up.
  • the locking slide (127) is guided upwards and can engage with its upper end (127a) in the engagement (107a) of the latch bolt (107).
  • the latch bolt (107) is driven out of the lock case (103) and fixed at the first dimension (M1) by the locking slide (127).
  • the door lock (1) according to the invention is now in the first position (I).
  • the energy source (117) has an inductive energy transmission which comprises a receiving coil (117a) accommodated in the lock case (103) and a transmitting coil (117b) arranged on the door frame side.

  • the motor-operated adjusting device (113) has a bell-shaped actuator which is in frictional contact with the socket coupling (111) via its end face arranged at right angles to its axis of rotation, the bell-shaped actuator having an end-face contour that is shaped that it holds the nut coupling (111) in at least one coupling position or in at least one uncoupling position of the nut half (109b) on the top side and the nut half (109a) on the bottom side.
  • the bell-shaped actuator according to the invention is cylindrical with a centrally arranged axis of rotation. In its rear or our part, it is positively connected to the axis of the motor-operated adjusting device (113). The front or upper part remains free. On the free end face of the bell-shaped actuator, which is at right angles to the axis of rotation, an end face contour is formed which, through its frictional contact with the socket coupling (111), enables the socket coupling (111) to be set, i.e. the coupling or decoupling of the socket half (109b) on the top side. and the nut half (109a) on the bottom.
  • the end face with its frontal contour is used to adjust the socket coupling (111) and not, as is often widespread in the prior art, the outer surface of a conventional adjusting device.
  • the travel distances to be managed by the motor-driven actuating device (113) are short, which means that their running times are short.
  • only small loads have to be moved for coupling the nut halves (109a, 109b) by means of the nut coupling (111) via the bell-shaped actuator by the motor-operated adjusting device (113), so that a significantly reduced energy consumption can be achieved.
  • the lock case (103) is preferably a standard lock case (mortise lock for tubular frame doors) according to DIN 18 251, Part 2 (as of September 2014), so that the lock according to the invention can in principle be used in any door with a standard receptacle.
  • the lock case (103) is a mortise lock for full leaf doors in accordance with DIN 18 251, Part 1 (as of September 2014).
  • the latch bolt (107) of the door lock (1) according to the invention can be extended by 20 mm from the lock case (103) and is preferably provided with injection-molded plastic inserts which ensure low-noise and low-wear closing.
  • the electronic radio module preferably forms part of a locking and access system which, in addition to the radio module, includes an antenna and the motor control (11305). 868 MHz is used as the frequency for the radio module.
  • backset dimensions of 35 mm, 40 mm, 45 mm and 50 mm as a tubular frame lock and backset dimensions of 55 mm, 60 mm, 65 mm, 70 mm and 80 mm as a mortise lock for full leaf doors are possible for the door lock (1) according to the invention.
  • the door lock (1) preferably comprises at least one microswitch, which is optionally in positive contact with the top or bottom socket half (109a, 109b), depending on where the outside handle is located, and is electrically connected to the motor control and the radio module is.
  • the socket coupling (111) can only be actuated by means of the adjusting device (113) when the microswitch detects the rest position of the scanned socket half (109a, 109b). According to the invention, only the socket half (109a, 109b) on the outside of the door is queried. It is not necessary to query the socket half (109a, 109b) on the inside of the door (panic function), since this can be actuated regardless of the coupling position of the socket (109). The panic function is thus always guaranteed, as it cannot block, regardless of where the nut coupling (111) is currently located.
  • the bell-shaped actuator has a device for querying the position.
  • This device for interrogating the position is preferably designed as a surface contour that is located on the end of the bell-shaped actuator opposite the front surface contour.
  • the coupled-in or uncoupled position of the nut coupling (111) is displayed, for example via a corresponding microswitch, in order to stop the rotation of the motor-driven adjusting device (113) when the respective position is reached.
  • This prevents the motor-driven adjusting device (113) from “moving on block” and thus preventing current load peaks from occurring.
  • the door lock (1) further comprises a mechanical lock cylinder (121) for mechanical actuation of the nut coupling (111).
  • a mechanical lock cylinder (121) for mechanical actuation of the nut coupling (111).
  • the locking cylinder (121) When the locking cylinder (121) is actuated, it takes over the function of the motor-operated adjusting device (113) and couples the nut halves (109a, 109b). In this way, in the event of a complete failure of the energy source (117), emergency unlocking of the lock (1) can be ensured.
