EP2407617B1 - Door with manually actuatable handle - Google Patents

Description

The invention relates to a door, in particular a front door, with a manually operable pusher and at least one catch, wherein the pusher for actuating the at least one catch is formed.

From the US 6,357,805 B1 is a door of typical American design with a knob instead of a pusher known. To be able to drive the door by a door drive, the knob is removed and replaced by a lever. A cable, which is windable on a motor driven cable drum, is attached to the lever to pull it down to open the door.

From the US 2002/0092237 A1 a door with a door handle and an opening mechanism is known, in which case a cable is connected for opening on the door handle.

From the US 5 095 654 A is a door with a door handle with a handle known, which is automatically actuated by a pulling mechanism.

From the DE 296 17 063 U1 a door is known in which a locking mechanism is formed by means of a toothed disc, which is placed on a door handle shaft, for automatically rotating the door handle shaft.

From the US Pat. No. 7,270,352 B1 a door with a foot-operated door opener is known which engages with a traction means or a linkage on a lever acting on a door handle shaft.

The EP 1 229 192 A2 describes a door locking system in which a door lock is motor driven driven.

From the DE 24 33 322 A1 is a multi-trap panic lock with multiple Schnappers known, which are operated together via a lever handle.

In the front doors available on the market is often provided on the outside of the door leaf, only a knob or rigid handle. The inside of the door leaf, however, usually has a pusher. In the closed state, at least one arranged on the end face of the door leaf, biased catch is in engagement with the frame of the front door. Such snappers are also called "trap". By pressing the handle from the inside, the pretensioned catch is withdrawn and the door leaf released. From the outside, however, the catch can be withdrawn only by actuating a cylinder with, for example, a key, so as to open the front door.

A catch can be easily pushed back by external manipulation. A full burglary protection is therefore only achieved when additionally interlock by locking in the frame to hold the door.

However, many people do not lock the front doors for convenience, especially during a short absence. In this case, the catch is the only area of intervention between the door frame and the door leaf. A break-in is particularly easy in this case.

An improvement brought house doors with multi-latch locks, which have several snaps, all of which must be pushed back simultaneously to open the door without authorization from the outside.

In addition to the traps described above, there are also entry doors available on the market that automatically lock themselves when they close. Here, either mechanically or by motor, bolts are extended on the door leaf, which engage in the frame and lock the front door. Examples of such front doors are in the DE 100 61 365 A1 , the DE 102 61 129 B4 and the DE 20 2006 004 553 U1 described, to which expressly referred. The advantage of such automatic locking, in particular when a plurality of bars are provided on the door leaf, consists in an increased anti-burglary protection against the presence of only a catch, which engages when it coincides with the frame.

The self-locking doors described in this case provide reliable protection against burglary, since the bars can be difficult or impossible to push back from the outside, especially when several bars are provided at different locations of the door leaf. The front door can be opened from the outside only by pressing the lock cylinder with a key or similar systems.

However, to be able to open the door quickly from the inside comfortably and in the sense of a panic function, it is possible to retract the latch and the latch on the door handle.

To open a front door are increasingly in the market to find systems in which the front door is not opened by a key, but by an electronic system from the outside, such as in the DE 60 2004 009 927 T2 described. For example, fingerprint scanners are known which identify a person by means of a fingerprint and then automatically release the door. In the case of multi-latches or multiple latches, however, the problem arises that an automatic unlocking involves a great deal of effort. If, for example, the door has a connection to an in-house telephone and is to be opened via a remote control, a separate release device must be provided in the frame for each catch. This is complex, complicated and error-prone.

The object of the invention is to provide a particularly safe, yet very comfortable to operate door, especially front door.

The object of the invention is achieved by a door with the features of claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

A door, in particular a front door, has a manually operable pusher and at least one catch, the pusher being designed to actuate the at least one latch. Further, an automatically driven pusher actuator is provided for actuating the pusher. With such an arrangement, the pusher can be actuated automatically and at the same time pull out the at least one catch from a frame of the door. This allows a door to be opened conveniently.

Further, in a door having a plurality of catchers or latches for burglary protection, these members can be easily retracted by operating the pusher via the pusher actuating means. Complicated release devices in the frame can be omitted so advantageous. So is a system for using a remote control uncomplicated on the door attaching bar.

The handle actuating device according to the invention is simply provided in the vicinity of the pusher on a door leaf of the door, so that a complex installation of an automatic unlocking is eliminated. Due to the surprisingly simple design of this now proposed unlocking it is also particularly easy to release a multiple locking device on a door by simply pressing the trigger on the automatically driven handle actuation device and so open the door.

Preferably, the door has a multiple engagement device with a plurality of engagement elements, which hold the door in the engaged state in a closed position, wherein a plurality of engagement elements are simultaneously movable by the pusher from its engagement position into a release position. A door with a multiple engagement device is advantageous for use as a front door. The more engagement points provided by the multiple engagement device from the door leaf to the frame, the more difficult it becomes for a potential burglar, to open the door. It is of particular advantage for authorized persons if all engagement elements formed on the multiple engagement device are simultaneously movable into their release position by the pusher. So it is easily possible to open the door by activating the handle operation device and thus the pusher.

Preferably, the multiple engagement means comprises a plurality of beaks operable by the pusher against a bias. Preloaded latches are pulled out of their engaged position by the pusher into a release position and automatically return to the engaged position when the pusher is released. If a door closes, this mechanism ensures that the door is held in a trap and can not open by itself. If there are several snaps, the door is preferably held more firmly in a closed position than if only one catch is present.

Particularly advantageously, the Mehrfacheingreifeinrichtung on at least one latch for locking the door, wherein the Mehrfacheingreifeinrichtung is designed such that the at least one bolt is moved when the door closes in its engaged position and can be brought back into its release position by handle operation or lock operation. Latches can advantageously not, as is often the case with snappers, be moved back by external manipulation, such as a credit card, so as to open a door unauthorized. Thus, arranged on the door bars advantageously provide better protection against burglary than just snap. It is advantageous if the bolt, when the door falls, is automatically moved into its engagement position and thus locks the door. Thus, burglary protection can be advantageously created even if, for example, a person leaves a house and the front door just behind him, but not complete. If the person returns, it is advantageous if the bolt can then be reopened via a cylinder actuation.

However, if the door closes while people are still in the house, it is advantageous if the latch only by pressing the lever back in his release order can be brought. This is particularly advantageous when the people in the house are in a dangerous situation, such as a fire.

According to the invention, the pusher actuating device is designed such that it exerts a compressive or tensile force in the orthogonal direction on the pusher.

By orthogonal alignment of the compressive or tensile force on the pusher, the force component is oriented perpendicular to the lever arm formed by the pusher. Thus, the entire force for depressing or - pull the pusher is used and the engagement means, for example, one or more snaps and / or one or more bars can be moved with a minimum force from their engagement position to a release position.

According to the invention, the pusher actuating device is arranged on a door leaf having the pusher.

Preferably, in use, the pusher actuator is disposed above a free end of the pusher. Such an arrangement is therefore particularly preferred, since so the handle actuating device is located directly at the point where it should ultimately act. If, moreover, it is arranged above the free end of the pusher, a maximum torque can advantageously act, since a longer lever arm is available for the same force action.

Advantageously, the pusher actuating device has a spindle or a magnet which applies the required force to the free end of the pusher in the form of a compressive or tensile force. However, the force can also be applied particularly preferably by a wire cable arrangement, a pulley or a direct drive.

In a particularly preferred embodiment, the pusher actuating means for actuating the pusher upon receipt of a signal from an identification device for identifying persons or a remote control device, such. a door phone, trained. An identification device can advantageously be, for example, a chip card which is read out by a read-out device on the front door, or else a fingerprint identification device. Thus, the identification device, after having recognized a stored person, can pass an enable signal to the pusher actuator. This can then advantageously operate the pusher to unlock the exemplary front door. This is particularly advantageous if the person concerned is fully packed and thus a lock operation is difficult with a key.

Advantageously, the identification device is arranged on a first side of the door leaf without pushers, wherein the pusher is arranged on an opposite second side of the door leaf. Thus, advantageously, a person can be identified by the identification device as known or unknown and the pusher be actuated only after signal through the identification device. From the inside, it is of particular advantage if no identification device is arranged, since especially in an emergency opening of the door without prior identification is desired.

When using a remote control, a signal originating from, for example, a door telephone need not be routed to one or more release devices in the frame of a front door, which release one or more snaps or latches. Rather, the signal is routed directly to the pusher actuator, and this can be the only element simply a catch / latch or release several snap bars.

a fourth embodiment of a handle set.

Fig. 1 and 2 show a first embodiment of a handle assembly 14 with a handle actuating device 16 according to a first embodiment.

Fig. 1 shows a door leaf 10 of, for example, a front door 12 with the handle set 14 and the handle actuating device 16. The handle set 14 has a pusher 18 with axis of rotation A and a rosette 20. In the rosette 20, a profile cylinder 22 is provided for locking the front door 12 with a key. The pusher 18 has a free end 24 which is spaced from the rosette 20. The pusher 18 thus defines a lever arm, via which a force acting in the direction of arrow B force can be transmitted.

About the free end 24, the handle actuator 16 is arranged. The arrangement of the pusher actuating device 16 over the free end 24 of the pusher 18 offers, on the one hand, the advantage that with a minimum force in the direction of the arrow B a maximum effect on elements actuated by the pusher 18 can be achieved, and at the same time a middle region 26 the pusher 18 remains free and so is still available for manual use.

The handle actuating device 16 has a housing 28 in which a drive element 30 is housed. Outside the housing 28, a fork 32 is positively connected to the free end 24. A force acting in the direction of arrow B, generated in the drive member 30 force is transmitted to the fork 32 and thus to the free end 24 of the pusher 18 via a power transmission element 34. The force acting in the direction of the arrow B then pushes down the pusher 18 so that it rotates about the axis A as in manual operation.

In Fig. 2 is a top view of a cross section through the door leaf 10 of the front door 12 is shown. It can be seen that the door leaf 10 on a first side 36 has the handle set 14 described above and the handle actuating device 16. On a second side 38 has the Door leaf 10 a push handle 40. In a folding region 42 of the door leaf, a catch 44 is arranged. The latch 44 is biased and can be withdrawn via a pusher pin 46 (shown in phantom) by the pusher pin 46 engages in a lock 48. In the view can be further seen that the pusher 18 is formed as a U-shaped pusher 18.

At the push handle 40, an identification device 50 is arranged for identifying persons located on the second side 38 of the door leaf 10. The identification device 50 may be, for example, a fingerprint scanner or a transponder reader or the like.

Fig. 3 shows a view of a disposed on the front door 12 multiple engagement means 52. On the multiple engagement means 52, an upper and lower latch 47, 46 and a third latch 58 is arranged. Furthermore, the multiple engagement device 52 has a catch 44. The latches 54, 56, 58 and the catch 44 are shown in their engagement position 60 shown. The latch 54, 56, 58 are not, as the catch 44, biased and thus constantly in the engagement position 60, but must be pushed into this, for example by an automatic lock operation or by operation with a key. The engaging elements 61 formed by the latches 54, 56, 58 and the catch 44 are movable directly or indirectly by the pusher 18 via the pusher pin 46 engaging in the lock 48 into a release position (not shown).

If the door leaf 10 of the front door 12 now closes, it is automatically locked by engaging the latch 54, 56, 58 and the latch 44 in a frame (not shown) of the front door 12.

If, in a first case, a person approaches the front door 12 from the second side 38 of the door leaf 10 and reaches for the push handle 40, the person identified as being known is identified by the identification device 50 in the form of, for example, a fingerprint scanner. The identification device 50 gives a signal to the drive element 30 of FIG Handle actuator 16 further so that it drives a power transmission element 34. The power transmission element 34 may be formed as a spindle 62 or 64 as a magnet. The force transmission element 34 presses the fork 32 on the free end 24 of the pusher 18. Due to the force of the pusher 18 rotates about the axis A and pulls it with the pusher 46 directly the catch 44 and indirectly the latch 54, 56, 58 in a release order. The person located on the second side 38 of the front door 12 now only has to open the door leaf 10 in order to be able to pass through the front door 12.

Since the pusher 18 is free in the central region 26, a person located on the first side 36 of the front door 12 in a second case can easily open the door leaf 10 by manual operation of the pusher 18 with the above described effects on the latches 54, 56, 58 or actuate the catch 44. Thus, the door leaf 10 can also be easily opened from the first side 36.

In addition, a profile cylinder 22 is provided in the rosette 20 for closing or opening the multiple engagement device. About this profile cylinder 22, the multiple engagement device can also be brought by actuation with a key in the release position. Should a fault arise on either the identification device 50 or the pusher actuation device 16, therefore, the door should continue to be opened in the usual way with a key.

According to one embodiment, not shown, the pusher actuating device 16 is provided in a multi-latch lock with a plurality of Schnäppern 44.

In the illustrated embodiment, the pusher actuator 16 is used in a multi-bolt lock with multiple latches 54, 56, 58. When slamming the front door 12 designed as a multi-bolt lock Mehrfacheingreifeinrichtung 52 is designed so that a lock 66 is automatically locked mechanically five times. From the outside, the front door 12 has unlocked be reset and the catch 44 by means of key or profile cylinder 22. From the inside, the operation runs on the pusher 18, since the lock 66 has a kind of panic function and so unlocked by pressing the pusher 18, the lock 66 and the catch 44 is withdrawn. A door release of this type is particularly advantageous for locks 66 with horizontal multiple engagement device 52. To manually operate the pusher 18, it is advantageous if the handle portion of the pusher 18 remains free for the hand. Thus, the force application is provided at the free end 24, ie the outer pusher end. Thus, a lower pressure force, but a longer path is provided. The housing 28, in which a drive element 30 is accommodated in the form of a motor mechanism, is ergonomically and designerically well adapted to the front door 12.

The force that must be applied by the drive element 30 results from the moment of a pusher retaining spring, which biases the pusher 18, from the withdrawal forces of the latch 44, which act against the bias of the latch 44, and the length of the pusher 18 and the resulting lever.

In the Fig. 5 to 10 Further embodiments of the handle set 14 and the handle actuating device 16 are shown.

Fig. 4 shows the handle set 14, in which the pusher 18 is attached to a design door plate 70. The design door plate 70 has a U-shaped recess 72 in the region of the free end 24 of the pusher 18. A shield plate 74 is curved parallel to this U-shaped recess 72. However, other forms of the shield plate 74 may be provided.

As in the Fig. 5, 6 and 8th can be seen, the free end 24 of the pusher 18 is aligned with the door leaf and protrudes into the recess 72 of the shield plate 74 a.

Thus, the pusher 18, as desired and technical constraints, both up and down to be moved, with an element which is disposed within the shield plate 74 can engage the pusher 18.

In a second embodiment of the pusher actuator 16, shown in FIG Fig. 5 , engages at the free end 24 of the pusher 18, the power transmission element 34, which transmits a force from the drive member 30 to the pusher 18 and this so, as desired, along the in Fig. 4 plotted arrows up or down presses. The drive element 30 is arranged in the door leaf 10 and therefore not visible from the outside.

In 6 and 7 a third embodiment of the pusher actuator 16 is shown. Here is the pusher 18 analogous to the in Fig. 5 shown pushers arranged such that its free end 24 protrudes into the recess 72 of the shield plate 74. In the shield plate 74, a motor element 76 and a holder 78 is provided. A wire 80 is stretched from the bracket 78 to the motor member 76 over the free end 74 of the pusher 18. By operating the motor member 76, the wire 80 is wound and further tensioned and thus pulls the pusher 18 in the direction of the motor member 76. Shown is an arrangement in which the pusher 18 is pulled down, but it is also possible, the arrangement reversed provided so that the pusher 18 is pulled upwards.

Fig. 8 shows a fourth embodiment of the handle actuating device 16. Here, in the shield plate 74, a further drive element 82 is provided, which has a driver 84. If the drive element 82 is running, the pusher 18 is pushed down via the driver 84, which protrudes beyond the free end 24 of the pusher 18.

As already mentioned, the embodiments shown can actuate the pusher 18 both downwards and upwards. For this purpose, the design door plate 70 according to the FIGS. 9 and 10 be equipped with a only quarter-circular recess 86 which extends either downwards or upwards.

A door handle operation for opening and closing a door leaf 10 is usually carried out manually by hand. In the case of automatic opening and door closers, the lock plate in the frame is withdrawn in a controlled manner to unlock the latch, thereby releasing the door. For multiple locking the door in the closing area of the frame requires an automatic unlocking a lot of effort. Therefore, in the described embodiment, a simple automatic system is described in which in a multi-bolt lock all bars 54, 56, 58 are withdrawn via a pusher 18 from the frame. For this purpose, the pusher 18 on the inside, i. the first side 36, the door leaf 10, automatically actuated by a force so that a multi-bolt lock retracts all the bars 54, 56, 58 from the frame at the same time. This is also possible with a normal latch lock.

At the free end 24 of the pusher 18 acts a compressive or tensile force, wherein a corresponding spindle drive or magnet, which is provided in a arranged on the door leaf 10 housing 28, applies the required force. A pusher 18, which is arranged horizontally, is applied with a vertical force and a pusher 18, which is arranged vertically, is acted upon by a horizontal force.

On a door leaf inside - first page 36 - a front door 12, a handle set 14 for actuating a latch 68 is attached. The pusher 18 is U-shaped. Above the U-shaped pusher 18, a pusher actuating device 16 is arranged in a housing 28. A drive element 30 is connected to a spindle 62, in particular a pressure spindle, and presses in the drive case (Entriegelungsfall) with a fork 32 on the bent free end 24 of the pusher 18. By pivoting the U-shaped pusher 18, the latch 68 is withdrawn. Immediately after this unlocking or opening the front door 12 completes the U-shaped pusher 18 via the fork 32 and the drive member 30 a retreat to the starting position. To the middle portion 26, ie the pusher engagement, for manual use not by the pusher actuator 16 to reduce, the pusher actuator 16 is preferably at the extreme end of the pusher 18, namely the free end 24, respectively.
