Description

The invention relates to a lock device for a movable building part or furniture part, in particular for a door, with a fastened to the building part or furniture part holder, connectable to the holder housing and a latch which is retractable into the housing and out of this. Furthermore, the invention relates to a door with such a lock device.

In the case of doors with a door leaf pivotally mounted relative to a door frame, a door latch is generally provided which actuates a bevelled latch, which can engage in a door frame-fixed strike plate.

A mostly underlying main latch can also be moved in and out of an underlying opening of the strike plate by means of a lock (usually a cylinder lock) to close the door, or to unlock.

In addition, it is known - usually above - the door handle to install an additional lock, which has a separate latch in a separate latch receptacle (strike plate). These additional locks are usually from the outside of the door by means of a key apparently and from the inside of the door by means of a hand-operated knob.

The object of the invention is to provide a further developed lock device, which is particularly suitable as additional lock for doors, which can be easily operated and which allows to realize increased security.

This is achieved by the features of claim 1 according to the invention.

The lock device according to the invention provides, instead of the previously used knob for actuating the bolt, that the housing itself is used for actuating the bolt. For this purpose, the housing is pivotally mounted on the holder, which can be screwed for example on the door leaf or otherwise attached thereto.

The latch may be mechanically coupled with the housing, so that depending on the pivot position of the housing relative to the holder and the latch position is automatically determined. In a case of an elongated housing usually horizontal blocking position of the bolt will be extended and protrude over the door leaf so that it can engage in a bolt receptacle, in particular a strike plate on the door frame and thus securely closes the door. By pivoting the - preferably substantially cuboid - housing by hand, which is easily possible due to the large attack surface, from the locked position with extended latch in an open position with retracted latch the lock device can be opened.

Particularly favorable is an embodiment in which is preferably provided in addition to the mechanical coupling of movement between the housing and bolt that a - preferably battery or battery-powered - electric motor drive for movement of the housing is provided relative to the holder, preferably provided a timing for the electric motor drive is that the housing over a - preferably adjustable - period of time from the locking position in which the bolt is extended, leads to an opening position and holds there, in which the bolt is retracted, then automatically return to the locked position.

• Einerseits kann ein solcher elektromotorischer Antrieb verwendet werden, um in einer Art Servo-Unterstützung die Verschwenkung des Gehäuses, welche per Hand initiiert wird, aus der Sperrstellung in die Offenstellung zu erleichtern. Andererseits kann ein solcher elektromotorischer Antrieb dazu verwendet werden, über eine Zeitsteuerung das Gehäuse über eine vorbestimmte Zeitspanne aus der Sperrposition heraus in einer Offenposition zu halten, in der der Riegel zurückgezogen und damit die Türe frei offenbar ist. Damit ist eine Einhandöffnung der Türe von innen leicht möglich, wenn die erfindungsgemäße Schlossvorrichtung als Zusatzschloss verwendet wird. Zunächst öffnet man durch die gegebenenfalls servounterstützte Öffnungsbewegung durch Angriff am Gehäuse und Verschwenken desselben den Riegel des Zusatzschlosses. Anschließend hat man eine bestimmte Zeitspanne Zeit, um durch Drücken der Klinke das Türblatt endgültig zu öffnen und den Raum zu verlassen.

Such an electromotive drive offers several advantages:

• On the one hand, such an electric motor drive can be used to facilitate in a kind of servo assistance, the pivoting of the housing, which is initiated by hand, from the locked position to the open position. On the other hand, such an electromotive drive can be used to hold over a period of time the housing over a predetermined period of time out of the locked position in an open position, in which the bolt is withdrawn and thus the door is freely exposed. For a one-handed opening of the door from the inside is easily possible if the lock device according to the invention is used as additional lock. First, it opens by the possibly servo-assisted opening movement by attacking the housing and pivoting thereof the bolt of the auxiliary lock. Then you have a certain amount of time to finally open the door leaf and leave the room by pressing the latch.

After the expiration of the period of time, the bolt of the lock device according to the invention closes automatically, so that the space is secured inside, even if the main lock is not locked. The door latch of the main lock can usually be opened quickly by simple mechanical action. This is not possible with the bolt of the additional lock, which does not have to be tapered.

Even if one concerns the space from the outside - which is often described below - closes the additional lock according to the invention automatically after a predetermined period of time and thus secures the interior.

Another advantage of the electromotive drive is that even without the need to introduce a key, for example via a coded remote control (chip), the additional lock can be opened from the outside and that simply by approaching and preferably over a predetermined period of time, then entering allowed into the room by opening the normal main lock. For this purpose, it is preferably provided that a non-contact with a coded remote control transmitter - in particular via a radio link - is provided receiving device via which a control device for the electric motor drive can be controlled. The term hand transmitter is to be seen very far, he does not necessarily have to send actively coded signals. It is also possible that the receiving device interrogates the coding of the remote control transmitter signals. It is important that the code represents the key, which is unique and only this particular code or key in electronic form controls the electric motor drive and moves to open the bolt.

In order to still allow access from the outside in case of failure of the - preferably battery or accumulator-bound power supply of an electric motor drive, it can be provided that a mechanical emergency release is provided on the housing with a suitable mechanical key relative to the holder or directly the bolt is movable. Although you have to use a suitable mechanical key here, you can also enter the room in the event of a power failure until you change the battery or recharge an accumulator. From the inside, if necessary, the servo support will fail in the event of a power failure, or the bolt may not be kept open because the housing usually tends to fall back into the locked position due to gravity. Then you have to hold in such a case by means of a two-handed operation with one hand, the housing in the open position and open the latch with the other hand. Even so, you can safely leave the room anyway, even if the power supply should not work for a short time.

In addition, it is possible with the lock device according to the invention to realize a kind of locking bar, in which not only on the side remote from the axis of rotation of the door leaf, a lock is provided, but also on the side of the pivot axis.

In such an embodiment, one must form the strike plate of the near-axis lock device so that it is not in the way when opening the door. One possibility would be a large distance of the bolt receptacle from the door edge, another possibility is to move the bolt receptacle, especially in the door frame form retractable. But it is also possible to store the bolt receptacle pivotable.

Further advantages and details of the invention will be explained in more detail with reference to the following description of the figures.

The FIG. 1 shows an embodiment of the invention with reference to the mounting position on an apartment door, the apartment door is shown on the inside.

The apartment door comprises a door frame 1 and a door leaf 2, which is pivotally mounted via hinges 3 in the usual way.

The standard equipment of a door also includes the door latch 4 with the door latch 5, which can engage in a schematically illustrated lock plate 6.

In addition, the door can be locked via a standard lock cylinder 7 and an extendable main latch 8, which also engages in the strike plate 6.

Above the door handle 4, a lock device according to the invention 9 is mounted and that on the hinges 3 facing away from the free longitudinal edge of the door. The lock device 9 has a latch 10, which can engage in a latch receptacle 11, which in turn is attached to the door frame 1, for example, is screwed. The lock device 9 according to the invention together with bolt 10 and bolt receptacle 11 will be described in more detail below. Based on FIG. 1 Yet another embodiment of the invention will be explained, namely the supplement drawn with dashed lines. He may namely for the realization of a "bar lock" on the hinges 3 facing longitudinal side of the door panel 2, a further inventive lock device 9a with latch 10a and latch receptacle 11a be provided which is substantially the same or mirror inverted formed to the lock device 9. The two lock devices 9 and 9a can also be connected to one another via a stable connection holder or bar 12, this connection taking place via the holders of the respective lock device mounted on the door leaf as described in more detail below, since the housing 14 or 14a can be moved to open is.

With reference to the FIGS. 2a to 2c Now an embodiment of the lock device according to the invention including the opening of the door is described from the inside closer.

The lock device 9 according to the invention has a (in the illustrated embodiment, plate-shaped) holder 13, which is fastened via not shown screws or other fastening means on the door panel 2. It is best to essentially flat on the door panel 2.

In addition, a housing 14 is provided, which is substantially cuboid (except for rounded edges left and right) is formed. In the housing, a bolt 10 is slidably mounted in the in FIG. 2a shown closed position engages in the latch receptacle 11, which is firmly attached to the door frame 1.

According to the movement of the bolt 10 from the closed position according to FIG. 2a in the open position according to FIG. 2b by pivoting the housing 14 relative to the holder 13, wherein the bolt is mechanically coupled in relation to the position of the housing relative to the holder, as will be explained in more detail below.

In the in the FIGS. 2a to 2c illustrated embodiment, the housing 14 about an axis 15 is pivotable.

To open the door from the inside to move the easily accessible housing 14 by hand in a pivoting movement according to the arrow 16 upwards, the latch 10 automatically retracts into the housing 14 by the movement coupling. Then you move the door handle 4 in the usual opening direction 17 down and then according to the Figure 2c to Unlock the lock device 9 and the main lock with the door handle 4 open the door and leave the room.

The FIGS. 3a to 3c show the opening process in an embodiment of the lock device according to the invention by opening from the outside. This is done without contact via a coded remote control transmitter 18, which controls a control device for an electric motor drive described in more detail below.

Starting from the closed door 3a one approaches with the remote control 18 of the door, thereby opening the internal lock device in a movement, as in the FIGS. 2a to 2c is shown by a built-in engine, which will be described in more detail below. Then you can turn the door handle 4 in the opening direction 17 press down and then according to Figure 3c enter the room from the outside.

Should a power failure occur and the electric motor in the lock device, which will be described in more detail below, not work or not work satisfactorily, there will be a key-operated emergency lock. For this purpose, a key 20 is inserted into the lock cylinder 19, which extends through the door leaf into the interior of the lock device and there by turning the key either directly pulls the bolt 10 or the housing 14 pivots about the pivot axis 15 relative to the holder 13, which is because of Motion coupling between the housing and latch again leads to the withdrawal of the bolt. You can then enter the room even in a power failure after the door handle 4 has been opened according to arrow 17 direction.

In FIG. 5 Now, the internal structure of an embodiment of a lock device 9 according to the invention is shown in more detail in a schematic representation.

The plate-shaped holder 13 is fastened by screws 23 on the door leaf. Other attachment methods such as bonding, are also quite conceivable and possible. On the plate-shaped holder 13 is seated a substantially cuboid housing 14, which according to the invention relative to the holder 13 is movable. At the in FIG. 5 illustrated embodiment, the movement is a pivoting about the pivot axis 15 and in the direction of the arrow sixteenth

The FIG. 5 shows the locking position, in which the bolt 10 which is mounted linearly displaceable in the direction of the double arrow 24 in the housing 14, protruding from the housing and thus can engage in a not shown here, for example, door frame fixed latch receptacle, whereby the door is locked.

The movement coupling according to the invention between the position of the housing 14 relative to the holder 13 on the one hand with the position of the bolt 10 on the other hand is in the in FIG. 5 schematically illustrated embodiment realized in that the housing inside a curved rack-shaped portion 25 is provided, whose curvature corresponds to a circular arc about the axis 15. With this curved rack portion 25 meshes a pinion 26 on which a lever 27 is rotatably connected. This lever 27 carries at the free end of a roller 28 which can move in a bolt 10 formed in the vertical groove 29.

If now the housing by hand (or as shown later) pivoted upward in the direction of arrow 16 about the axis 15, the pinion 26 and thus the lever rotates 27. The roller 28 slides in the groove 29 upwards and pushes the bolt inside the case.

The dimensions are shown here only schematically. The can be easily formed so that the movement stroke is sufficient by pivoting the housing to completely retract the latch 10 into the housing.

In addition to the mechanical operation by hand, in the illustrated embodiment, the housing 14 with respect to the holder 13 can be pivoted by motor and motor M, 30. This motor M drives a gear 31, the simplified illustrated in the illustrated embodiment, a lever 32 in the arrow direction 33 pivots and thus via a roller 34, which rests, for example, on an inner edge of the housing 14, the housing can pivot upwards, because the motor M, 30 is energized accordingly.

For controlling the motor, a control device 36 is provided, which derives its energy from a battery or an accumulator 32. The control device allows the realization of numerous functions. Once it is possible that the control device, the originally manually initiated movement of the housing 14 includes. This can be detected from the motor current itself. But there is also the possibility, for example, to detect the position of the gear 31. Depending on the detected movement by hand, the motor can then supportively pivot the housing upwards in the sense of servo assistance.

In addition, a timing can be realized in which the motor keeps the housing 14 pivoted upwards in the open position, with which the bolt is retracted. This allows for a while to leave the room after opening. Only after a certain time, the housing falls down again by gravity and the bolt closes automatically. To support gravity, a spring, not shown here, or a positive drive can be provided via the motor. The length of time the housing is up and the latch open can be adjusted.

In addition, it is possible that the control device communicates with a receiving device 35, which cooperates with a coded remote control transmitter 18, which may also be arranged outside the door leaf and allows communication through the door panel. Wireless connections are preferred connections but also inductive or purely magnetic couplings are conceivable and possible. Preferably, it will provide a non-contact cooperation between the receiving device and the coded transmitter.

Upon access to the door from the outside with the transmitter 18, the receiving device on receipt of the correct code control device 31 so that the motor M, 30 pivots the housing 14 upwards and thus retracts the latch 10 and ultimately the access to the room allows. Basically you can of course also use the transmitter from the inside. If you have plugged it, for example, the lock device according to the invention opens automatically when entering the door in this embodiment, without the need for a manual pivoting or sliding movement upwards.

In FIG. 5 one also sees a lock cylinder 37, which by means of a key 20 (see FIG. 4b ) is pivotable from the outside in the direction of arrow 38 when the key fits. Thus, an emergency release is possible from the outside, even if the engine M, 30 fails. The lock cylinder engages with a conventional projection 39 in the groove-shaped receptacle 40 on the bolt 10 and moves it in the direction of arrow 24th

In the FIGS. 6a to 6c a lock device 9a according to the invention is shown as (reversed) in FIG. 1 is shown. It is an additional lock device near the hinges 3 on the inner edge of the door leaf. The lock device 9a may be constructed substantially the same as the lock device 9. Only in the bolt receptacle 11a must take precautions so that when opening the door this does not collide with the housing 9a. For this purpose, the bolt receptacle 11a, for example, movable, in particular in the door frame 1 retractable be trained and that spring-loaded, so that it jumps out after pushing in the door frame 1 through the housing 9a when fully opening the door and in the closed position of the door panel again provides the receptacle for the bolt.

The FIGS. 7a and 7b show a bow-shaped latch receptacle 11a, the pivotable (instead of as in the FIGS. 6a to 6c retractable) is mounted on the door frame 1 in order to avoid a collision with the opening door.

The invention is not limited to the illustrated embodiments. For example, the lock device according to the invention is also suitable for closing other parts of the building or furniture parts, such as windows or drawers.

The structural design may differ from the illustrated structure.
