Definitions
- the present invention relates to a door lock having an improved sequence control and preferably an inductive power transmission.
- the security serving building doors especially escape doors or fire doors, are usually provided with security locks in which close after closing the door this door self-closing, so that, for example, the fire can not overturn in other rooms in case of fire.
- security locks must allow a keyless operation from the inside to allow people to leave a room or building in any case.
- the security locks built into escape doors or fire doors often have a different mechanism from the conventional latch-and-bolt mechanism with an automatically extending latch bolt or locks with an automatically extending latch, which are known per se in the prior art (so-called self-locking locks) ,
- Electromechanical door locks can in principle receive their power supply on the one hand via a power supply by wiring from the frame through the door leaf to the castle or on the other hand operated with one or more batteries.
- the installation cost is very high. It is necessary to lay cables in the wall, make a cable transition between the frame and the door leaf and expose the door leaf for the cable to the lock. In particular, the cable transition is susceptible to interference. Wired locks are also susceptible to manipulation.
- Battery-operated locks have the disadvantage that the battery life is limited and thus regularly the batteries must be replaced. Due to space constraints, no larger batteries with higher capacity can be used in locks. Also, possible status monitoring and feedback are often kept as low as possible to increase battery life. Although there is often a battery status indicator (warning that the battery should be swapped), it is commonly used in larger objects such as a car. Hotels have regularly replaced the batteries, although these are not yet empty, in order to keep the effort of the technical staff as low as possible. Also, the performance of batteries in door locks decreases when used in exterior doors due to low outside temperatures in winter. Furthermore, batteries must be disposed of properly. One solution to the problem may be contactless energy transfer.
- DE 36 12 761 C2 describes an energy transfer between striking plate and lock, wherein the transmitting and receiving side should preferably be adjustable in order to obtain the best possible near transfer position to each other.
- the transmitter side are designed horizontally and the receiver side vertically adjustable.
- a disadvantage is the adjustability on the lock side to the effect that in the castle of the corresponding space for the receiver and the adjusting device in addition to the conventional lock mechanism with latch and bolt is very low and therefore expensive and delicate. Due to the lack of space, the receiver side can only be designed very small. As a result, the power transmission is rather low and it takes a longer period for transmitting the necessary energy. This can lead to functional problems when using the lock in practice.
- the object of the present invention is to provide a door lock in which the sequence control is improved such that the latch bolt does not extend when when the door is open, the tax trap is actuated.
- Another object of the present invention is to provide a door lock with inductive power transmission, which is independent of a wired or battery-powered power supply.
- a locking system with the door lock according to the invention is to be provided.
- a door lock (1) comprising
- control latch (125) via a spring-loaded
- Lock slide (127) with the latch bolt (107) is in operative connection, so that
- the latch bolt (107) in a first position (I), the latch bolt (107) is biased out of the lock case (103) by a first amount (M1) and the control catch (125) is fully extended out of the lock case (103), the catch slider (127) with its upper end (127a) is received in an engagement (107a) of the latch bolt (107) and this locks and rests with its lower end (127b) on a cam (125a) of the control latch (125),
- Lock case (103) is pressed, wherein the locking slide (127) with its upper end (127 a) in the engagement (107 a) of the latch bolt (107) is received and locks and is simultaneously blocked by the bias of the latch bolt (107) itself, while the lower end (127b) is free in a control cam (125b) of the control latch (125),
- the door lock (1) is characterized in that the control latch (125) via a spring-loaded locking slide (127) with the latch bolt (107) is in operative connection, so that
- the latch bolt (107) in a first position (I), the latch bolt (107) is biased out of the lock case (103) by a first amount (M1) and the control catch (125) is fully extended out of the lock case (103), the catch slider (127) with its upper end (127a) is received in an engagement (107a) of the latch bolt (107) and this locks and rests with its lower end (127b) on a cam (125a) of the control latch (125),
- the latch bolt (107) in a fourth position (IV) the latch bolt (107) is biased out of the lock case (103) by a second amount (M2) and locked by a latch (129), while at the same time the control latch (125) is partially or fully engaged in the latch Lock case (103) is depressed, wherein the locking slide (127) with its upper end (127 a) the latch bolt (107) no longer locks and with its lower end (127 b) in the control cam (125 b) of the control latch (125) rests.
- 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 an intentional or unintentional manipulation of the control latch (125) is effectively prevented, so that the original functions of escape doors or fire doors remain guaranteed. Due to the optimized sequence control for the latch bolt (107), a conventional latch in the door lock (1) according to the invention is no longer necessary, which simplifies the construction. Furthermore, a safe and at the same time inexpensive energy supply for the preferably electromechanical door lock (1) is created in an advantageous manner.
- the created by the no longer necessary free space in the door lock on the one hand can accommodate an inductive power supply with a larger receiving unit, and thus it can be a faster charging of the lock side energy storage can be realized.
- larger energy storage elements for example, larger capacitors or accumulators can be used.
- a power supply with a conventional battery can be implemented in a simple manner, if on the frame side no power connection for an inductive energy transmission is present or can be created.
- the entire control electronics including transmitting and receiving module can be accommodated in this area compact and protected.
- the present invention relates to a door lock (1) comprising a lock case (103), a Stülp (105) connected to the lock case (103), a latch bolt (107) resiliently biased out of the lock case (03), a two-piece Nut (109) with spring-mounted, adjustable nut coupling (111) and a control latch (125).
- a door lock (1) comprising a lock case (103), a Stülp (105) connected to the lock case (103), a latch bolt (107) resiliently biased out of the lock case (03), a two-piece Nut (109) with spring-mounted, adjustable nut coupling (111) and a control latch (125).
- the door lock (1) according to the invention is characterized in that the control latch (125) via a spring-loaded locking slide (127) with the latch bolt (107) in Active connection is, so that in principle four positions (I, II, III, IV) of latch bolt (107) and control latch (125) are made possible.
- the latch bolt (107) In a first position (I), the latch bolt (107) is biased out of the lock case (103) by a first amount (M1) and the control latch (125) is fully extended out of the lock case (103).
- the locking slide (127) With its upper end (127 a) in an engagement (107 a) of the latch bolt (107) is received and locks it. With its lower end (127b) rests the locking slide (127) on a cam (125a) of the control latch (125).
- This first position (I) describes an open door in which the latch bolt (107) is biased out of the lock case (103) and protrudes by the amount (M1) via the turn - up (105) (see Fig. 1, Fig. 2).
- the control catch (125) is fully extended and holds with a cam (125a) at its end the locking slide (127) 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 further extension thereof to a level 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) with an open door.
- a second position (II) the latch bolt (107) is biased out of the lock case (103) when the control catch (125) is partially or fully pressed into the lock case (103).
- the locking slide (127) with its upper end (127 a) in the engagement (107 a) of the latch bolt (107) is received and locks it.
- the lower end (127b) is free in a control cam (125b) of the control latch (125).
- This second position (II) describes the case that the door is open, as in the first position (I), the control latch (125) but consciously or unconsciously operated, that is, in the lock case (103) is pressed (see Fig. 3).
- the depression of a control latch or auxiliary latch causes an automatic extension of the latch bolt or the (automatic) bolt.
- This third position (III) describes the deliberate or intentional closing of the door.
- the door is open.
- latch bolt (107) and the control latch (125) on the strike plate (7) are pressed into the lock case (103).
- latch bolt (107) and control latch (125) are now the locking slide (127), which just just with the latch bolt (107) mutually blocked released and by the burden of a locking slide spring in the release position for the latch bolt (107 ) postponed.
- the latch latch (107) is biased out of the latch box (103) by a second amount (M2) and locked by a latch (129), while at the same time the latch (125) is partially or fully inserted into the latch box (103) is pressed in (see Fig. 5).
- the locking slide (127) with its upper end (127a) no longer locks the latch bolt (107) and rests with its lower end (127b) in the control cam (125b) of the control latch (125).
- This fourth position (IV) follows in the sequence control according to the invention directly to the third position (III). Since the door is now closed, the control catch (125) sits on the strike plate (7) and remains pressed into the lock case (103), leaving the lock slide (127) in the release position. After being released by the locking slide (127) displaced in the release position, the latch bolt (107) can now be completely extended out of the lock case (103) by virtue of its prestressing. The latch bolt (107) then protrudes by the second dimension (M2) beyond the turnout (105) and engages in the corresponding opening of the striking 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) with a closed door.
- the control catch (125) protrudes approx. 8.5 mm out of the cover (105).
- a state is described in which the control latch (125) is pushed in less than about 8.5 mm and up to about 2.5 mm (which corresponds to a door gap of 6 mm to 0 mm).
- a pusher (handle) communicating with the nut (109) is actuated in the usual way, so that the Trap bolt (107) is fully retracted into the lock case (103) and an opening of the door is possible.
- the control catch (125) previously seated on the striking plate (7) moves completely out of the lock case (103) due to the acting spring load.
- the lower end (127b) of the lock slider (127) is guided on the control cam (125b) of the control latch (125), and the cam (125a) goes up.
- this further comprises a motor-operated adjusting device (113) for the nut coupling (1 11), an electronic radio module and an energy source (117) for the adjusting device (113) and the radio module.
- 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 electromechanical door lock (1) provided in this way has the advantage that the motor-driven adjusting device (113) only has to move small loads and to handle short travel ranges due to the configuration of the electric motor-driven nut coupling (111). As a result, compared to the prior art significantly reduced energy consumption is achieved.
- the inductive energy transfer of the energy source (117) ensures a safe, robust and simple power supply that is independent of a wired or battery-powered supply. With the use of inductive energy transfer, the environment is less burdened by the fact that the entire battery cycle of production, disposal and recycling is eliminated, so the natural resources are spared.

- Figures 7a and 7b show detailed illustrations of the control catch 125 according to the invention and the locking slide 127 according to the invention as important components of the improved sequence control of the present invention.
- FIG. 8 shows schematically how the receiving coil 117a of the door lock 1 according to the invention is received in the lock case 103, so that the space 10309 behind it remains free for the control electronics. It can also be seen how the receiving coil 117a takes advantage of the maximum possible space.
- the door lock (1) according to the invention initially has a lock case (103) with a lock case insert, a floor and a ceiling, and a cover (105) connected to the lock case (103). From the lock case (103) out a latch bolt (107) is resiliently biased.
- the door lock (1) further comprises a two-piece nut (109) with a cover-side nut half (109b) and a bottom-side nut half (109a) and a spring-loaded, adjustable nut coupling (111).
- a motor-driven adjusting device (113) is provided which has an electric motor with a motor control.
- the door lock (1) comprises an electronic control with electronic radio module and energy source (117) for the adjusting device (113) and the radio module.
- the motor-operated adjusting device (113) has a bell-shaped actuator, which is in frictional contact with the nut coupling (111) via its end face arranged at right angles to its axis of rotation, wherein the bell-shaped actuator has an end-face contour which is as follows is formed so that it holds the nut coupling (111) in at least one coupling-in position or in at least one coupling-out position of the cover-side nut half (109b) and the bottom-side nut half (109a).
- the bell-shaped actuator according to the invention is designed cylindrically with a centrally arranged axis of rotation. It is in its rear, or our part non-positively connected to the axis of the motor-operated adjusting device (1 13). The front or upper part remains free. At the free end surface of the bell-shaped actuator, which is perpendicular to the axis of rotation, an end-face contour is formed, which by their frictional contact with the nut coupling (111), the points of the nut coupling (111), i. coupling or uncoupling of the cover-side nut half (109b) and the bottom-side nut half (109a).
- the end face with its end-face contour is used to place the nut coupling (111) and not the lateral surface of a conventional setting device, as is often the case in the prior art.
- the travel paths to be managed by the motor-operated adjusting device (113) are short, so that their running times are low.
- the motor-operated adjusting device (1 3) only small loads to move, so that a significantly reduced energy consumption can be achieved.
- the lock case (103) is 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 Norming.
- the lock case (103) a mortise lock for full-leaf doors according to 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 out of the lock case (103) and preferably provided with molded plastic inserts which ensure a low-noise and low-wear closing.
- the electronic radio module preferably forms part of a locking and access system which comprises, in addition to the radio module, an antenna and the motor control (11305).
- the frequency used for the radio module is 868 MHz.
- mandrel dimensions of 35 mm, 40 mm, 45 mm and 50 mm and as mortise locks for full-leaf doors mandrel dimensions of 55 mm, 60 mm, 65 mm, 70 mm and 80 mm are possible for the door lock according to the invention (1) as a tubular frame lock.
- the door lock (1) preferably comprises at least one microswitch which is in frictional contact optionally with the cover-side or bottom-side nut half (109a, 109b), depending on which the outer handle is located, and is electrically connected to the motor control and the radio module is.
- the nut coupling (111) by means of the adjusting device (113) can only be actuated when the microswitch detects the rest position of the queried nut half (109a, 109b). According to the invention, only the nut half (109a, 109b) on the outside of the door is interrogated.
- a query of the nut half (109a, 109b) on the inside of the door (panic function) is not necessary, since it can be operated independently of the coupling position of the nut (109).
- the panic function is always guaranteed because it can not block, no matter where the nut coupling (111) is currently.
- the bell-shaped actuator has a device for interrogating the position.
- this device is designed to query the position as a mantle-shaped contour, which is located at the opposite end face of the end face of the bell-shaped actuator.
- the coupled or disengaged position of the nut coupling (111) is displayed, for example, via a corresponding microswitch to stop the rotation of the motor-operated adjusting device (113) upon reaching the respective position. This prevents the motor-operated adjusting device (113) from “locking up” and thus generating power load peaks.
- the door lock (1) further comprises a mechanical lock cylinder (121) for the mechanical actuation of the nut coupling (111).
- the positioning lug of the lock cylinder (121) takes over the function of the motor-operated adjusting device (113) and couples it when actuated the nut halves (109a, 109b).
