Abstract

A door, in particular a front door (12), is proposed which has a manually operated handle (18) and at least one catch (44), the handle (18) being designed to actuate the at least one catch (44). When in use above the handle (18), an automatically operated handle actuation device (16) is provided for actuating the handle (18).

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.

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 By pressing the handle from the inside, the pretensioned catch is withdrawn and the door leaf released. From the outside, however, the catch can be withdrawn only by actuating a cylinder with, for example, a key, so as to open the front door.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 , of the DE 102 61 129 B4 and the DE 20 2006 004 553 U1 described, to which expressly referred. The advantage of such an automatic locking, in particular if a plurality of bars are provided on the door leaf, consists in an increased burglary protection against the presence of only one 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, as for example 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 so advantageous omitted. Thus, a system for using a remote control is easy to attach to the door.

A handle operating device can be easily 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 latches 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 closing the door in its engagement 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.

But if the door closes while people are still in the house, it is advantageous if the bolt can be brought back into its release position only by pressing the trigger. This is particularly advantageous when the people in the house are in a dangerous situation, such as a fire.

Preferably, 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 is used to push or pull the pusher 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 in a release position.

Preferably, the handle actuating device is arranged on a door leaf having the pusher. Further preferably, the pusher actuator is disposed in use 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 device for actuating the pusher after receiving a signal from an identification device for identifying persons or by a remote control device, such as As 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 for unlocking the example 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.

Embodiments of the invention are explained below with reference to the accompanying drawings. It shows:

1 and 2 show a first embodiment of a handle set 14 with a handle operating device 16 according to a first embodiment.

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

Over the free end 24 is the handle actuator 16 arranged. The arrangement of the handle actuator 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 arrow B maximum effect on by the pusher 18 actuated elements can be achieved, and that at the same time a middle range 26 of the pusher 18 remains free and remains available for manual use.

The handle operation device 16 has a housing 28 on, in which a drive element 30 is housed. Outside the case 28 is form-fitting with the free end 24 a fork 32 connected. About a power transmission element 34 becomes an acting in the direction of arrow B, in the drive element 30 generated power, on the fork 32 and thus to the free end 24 of the pusher 18 transfer. The force acting in the direction of the arrow B then presses the pusher 18 down so that it rotates about the axis A as in manual operation.

In 2 is a top view of a cross section through the door leaf 10 the front door 12 shown. It can be seen that the door leaf 10 on a first page 36 the handle set described above 14 and the handle actuator 16 having. On a second page 38 shows the door leaf 10 a push handle 40 on. In a fold area 42 the door leaf is a catch 44 arranged. The flycatcher 44 is preloaded and can be accessed via a pusher pin 46 (dashed lines) are withdrawn by the pusher pin 46 in a castle 48 intervenes. In the view can be further seen that the pusher 18 as a U-shaped pusher 18 is trained.

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

3 shows a view on one at the front door 12 arranged multiple engagement device 52 , At the multiple engagement device 52 is an upper and lower bar 47 . 46 and a third bar 58 arranged. Next, the multiple engagement device 52 a flycatcher 44 on. The bars 54 . 56 . 58 as well as the catch 44 are in their intervention position 60 shown shown. The bars 54 . 56 . 58 are not like the flycatcher 44 , biased and thus constantly in the intervention position 60 but must be pushed into it, for example by an automatic lock operation or by operation with a key. The through the bars 54 . 56 . 58 and the flycatcher 44 formed engaging elements 61 are directly or indirectly through the pusher 18 over the into the castle 48 engaging pusher pin 46 in a release position (not shown) movable.

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

Occurs now in a first case from the second page 38 of the door leaf 10 A person at the front door 12 zoom in and grab the push handle 40 , is determined by the identification device arranged there 50 in the form of, for example, a fingerprint scanner identifies the person as known. The identification device 50 gives a signal to the drive element 30 the handle actuator 16 continue, so this is a power transmission element 34 drives. The power transmission element 34 can as a spindle 62 or as a magnet 64 be educated. The power transmission element 34 pushes the fork 32 to the free end 24 of the pusher 18 , Due to the action of force, the pusher rotates 18 about the axis A and pulls it with the pusher pin 46 directly the catch 44 or indirectly the bars 54 . 56 . 58 in a release position. The second page 38 the front door 12 The person must have the door leaf 10 now only belch to the front door 12 to be able to pass through.

Because the pusher 18 in the middle area 26 is free, one in a second case on the first page 36 the front door 12 Person located the door leaf 10 simply by manual operation of the pusher 18 with the above-described effects on the bars 54 . 56 . 58 or the catch 44 actuate. Thus, also from the first page 36 from the door leaf 10 be opened easily.

In addition, for closing or opening the multiple engagement device and a profile cylinder 22 in the rosette 20 intended. 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 occur on either the identification device 50 or the pusher actuator 16 Therefore, the door is in the usual way with a key continue to open.

According to an embodiment, not shown, the handle actuating device 16 in a multi-trap lock with several Schnäppern 44 intended.

In the illustrated embodiment, the pusher actuator 16 in a multi-bolt lock with multiple bars 54 . 56 . 58 used. When slamming the front door 12 is designed as a multi-bolt lock Mehrfacheingreifeinrichtung 52 designed to be a castle 66 automatically mechanically locked five times. From the outside must be the front door 12 unlocked and the catch 44 by means of key or profile cylinder 22 be reset. From the inside, the operation runs on the pusher 18 because the castle 66 has a kind of panic function and so by pressing the pusher 18 the castle 66 unlocked and the flycatcher 44 is withdrawn. A door release of this kind is especially in locks 66 with horizontal multiple engagement device 52 advantageous. To the pusher 18 also to operate manually, it is advantageous if the grip area of the pusher 18 remains free for the hand. This will be the force attack on the free end 24 , ie the outer pusher end provided. Thus, a lower pressure force, but a longer path is provided. The housing 28 in which a drive element 30 is housed in the form of a motorized mechanism, is ergonomically and designerically well on the front door 12 customized.

The force generated by the drive element 30 must be applied, results from the moment a pusher holding spring, the pusher 18 harnessed, from the retreat forces of the latch 44 that is against the bias of the latch 44 act, and from the length of the pusher 18 and the resulting lever.

In the 5 to 11 are further embodiments of the handle set 14 and the pusher actuator 16 shown.

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

As in the 5 . 6 and 8th to see is the free end 24 of the pusher 18 aligned with the door leaf and protrudes into the recess 72 the shield plate 74 one.

Thus, the pusher 18 , as desired and technical constraints, both up and down to be moved, with an element inside the shield plate 74 is arranged on the pusher 18 can attack.

In a second embodiment of the handle actuating device 16 represented in 5 , engages the free end 24 of the pusher 18 the power transmission element 34 that is a force from the drive element 30 on the trigger 18 transfers this and so, as desired, along the in 4 plotted arrows up or down presses. The drive element 30 is in the door leaf 10 arranged and therefore not visible from the outside.

In 6 and 7 is a third embodiment of the handle actuator 16 shown. Here is the pusher 18 analogous to the one in 5 shown pushers arranged such that its free end 24 into the recess 72 the shield plate 74 protrudes. In the shield plate 74 is a motor element 76 as well as a holder 78 intended. A wire rope 80 is from the bracket 78 to the engine element 76 about the free end 74 of the pusher 18 curious; excited. By actuating the motor element 76 becomes the wire rope 80 wound up and stretched further and thus pulls the trigger 18 towards the engine element 76 , Shown is an arrangement in which the pusher 18 However, it is also possible to provide the arrangement reversed, so that the pusher 18 is pulled up.

8th shows a fourth embodiment of the handle actuator 16 , Here's the shield plate 74 another drive element 82 provided that a driver 84 having. Runs the drive element 82 , becomes the pusher 18 about the driver 84 that's about the free end 24 of the pusher 18 sticks out, pressed down.

As already mentioned, the embodiments shown can be the pusher 18 both down and up press. This can be the design door sign 70 according to the 9 and 10 with only a quarter-circle-shaped recess 86 be fitted, which extends either downwards or upwards.

In a fifth embodiment of the handle actuating device 16 is in the rosette 20 about the axis A a direct drive 88 arranged. This direct drive 88 is directly with a fortified end 90 of the pusher 18 connected and pressed so the pusher 18 without further intermediate elements.

A door handle operation for opening and closing a door leaf 10 is usually done 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 bolts 54 . 56 . 58 via a pusher 18 be withdrawn from the frame. This is the pusher 18 on the inside, ie the first page 36 , the door leaf 10 , automatically actuated by a force so that a multi-bolt lock all latches 54 . 56 . 58 retracts 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, with a corresponding spindle drive or magnet, in one on the door leaf 10 arranged housing 28 is provided, the required force applies. A pusher 18 , which is arranged horizontally, is applied with a vertical force and a pusher 18 , which is arranged vertically, is applied with a horizontal force.

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