The drawbar is coupled to a door opening mechanism (35) provided with an electromechanical or electromagnetic drive. The closing device incorporates an energy store, e.g. a spring, which is compressed when the door is closed, and when released, operates the drawbar to unlatch the door.

Description

Interlocking device.

The invention concerns a device of interlocking for a door, a window or similar, with the characteristics of the object of claim 1.

An interlocking device of this type for example of EP 798 436 A2. This device of interlocking has the essential advantage that the door can be retain and also interlock using the latch bolt outside from the center, that is, at least in the corner area. When a door provided with this interlocking device falls on the lock, first the locksmith on the side of the frame door pushes the latch bolt in, bringing Allow the door to close. When the door is in closing state, the latch bolt is pushed out of the additional closing box and goes from the latch position to a interlocking position. Since the latch bolt is secured in this bolt position and cannot be pushed towards back in an unauthorized way, it is not possible to unlock this additional lock by inserting a flat tool into the groove What's between the door and the frame. A locked door of this Shape offers high resistance against theft.

But it has been shown that although said type of Doors can be opened manually without problems, they are necessary expensive modification work or auxiliary devices for your automatic opening, for example by means of a device opening electronically operated electromagnetically. Would it is necessary to place the same number of electronic devices of opening in the door frame than existing latches. This It is not only expensive but also very complicated and affects negatively to the appearance of the door or frame, since the electronic opening devices present the corresponding recesses Usually with electronic devices of normal opening latches can be unlocked whose length external in ejected state (outside the box) is between 10 and 15 mm However the latches with an expulsion greater than by example 20 mm cannot be unlocked by devices electronic opening of this type.

The invention, therefore, has as its mission perfect an interlocking device of the type mentioned in principle, so that it can also be removed electrically the door lock, the window or the like.

This task is solved according to the invention. with an interlock device solved in the way that indicated in claim 1.

In the following description it is only done reference to a door, although the forms of execution are equally suitable for windows or other lockable leaves. He interlocking device according to the invention offers the advantage essential that the door is locked by the boxes additional closing when it is closed and yet can be opened electrically, since the drive unit move the coupling bar in the opening direction. Through this coupling bar the latch bolts are move from their bolt positions, passing through the position of latch, to the open position, that is, fully retracted inside the closing box. In this position, the bolts latch no longer prevent the opening of the door.

Electric motors have the essential advantage of that it is not necessary to accumulate energy and that with these electric motors relatively high forces can be transmitted. To do this, the electric motor gears with the coupling rod by means of a gear multiplier. Small engines are known, eventually with protection against overheating, whose voltage of service basically corresponds to the service voltage of door interphones. This makes unnecessary a additional power supply and corresponding cabling. However, this also applies to the execution Electromagnetic or electromechanical.

The electric motor can be activated in both directions of rotation In this way, the motor will be activated in one direction. turn to unlock the door, which will move the tie rod to the open position. In this position the electric motor is maintained for an eligible period of time and at It is then activated by a control unit and rotates again in the other direction by moving the coupling rod to the position of closing.

Preferably it will be an electric motor that can be activated or rotated by an impulse. This too it is possible through a control unit that only requires a impulse to shoot.

In an example of execution it is expected that the box main closure is provided with a connecting rod and a change, which the connecting rod has a protrusion protruding from the plane of the connecting rod in the direction of change and the projection act in combination with the change and drag to it when the connecting rod is moved in opening address In this way, when moving the connecting rod, the which is attached to the coupling bar of the main box closing, the latch will also retract into the box, so that the electronic device can be deleted Conventional opening for the main box latch closing.

Preferably, the projection is formed by a tongue that protrudes from the connecting rod. This outgoing gear in a rivet of change. This conditioning has the essential advantage that almost equal components can be used in the main closing box either equip or retrofit boxes of conventional main closure with components according to invention.

Other advantages, features and details of invention are derived from the subclaims and the following description, which details the preferred execution examples. The characteristics represented in the drawings and mentioned in the claims and in the description may be essential for the invention both separately and in any of its combinations. The drawings show the following:

The example of running a device from interlocking depicted in figure 1, generally referred to as Execution example 1, presents a main closing box 2 as well as two additional closing boxes 3. The closing boxes 2 and 3 are fixed to a strip 4. The main closing box 2 is closed with a box lid 5 and you can recognize a nut from the latch 6, a locking cylinder 7, a latch 8 and a bolt 9. The latch 8 is in the latch position, so that the strike 33, represented in figure 3 and found in the door frame, you can push it inside the box main closing 2. Additional closing boxes 3 are also provided with a latch, constituted as locks of latch 10. Also latch bolts 10 are located in the latch position and therefore the striker 33 can push them into their respective additional boxes of close 3. Finally, you can also see a bar coupling 11 connecting the drive of the main housing of closing 2 with that of the additional closing boxes 3.

Figure 2 shows the additional closing box 3 without the cover, in which the latch bolt is housed movable shape in the direction of the transverse line III - III. This latch bolt 10 is in its removed position, that is, in its bolt position. Latch bolt 10 is provided with a slot 12 open on one side (figure 3) that It runs in its longitudinal direction. In this slot 12 there is a locking element 13 which is rotatably housed in the slot 12 around a retaining sleeve 14 and with it also on latch bolt 10. This locking element 13 is provided with a locking heel 15.

In the latch position (not shown), the locking heel 15 grabs the strip 4 behind and prevents the latch bolt 10, subjected to spring tension, follow moving out. This spring tension is generated by a latch ejection spring 16 (figure 2) placed in a spring guide pin 17 that rests on one side on the wall inside the housing of the additional closure box 3 and on the other side on a latch eject lever 18. This lever ejection of latch 18 is rotatably housed in a bearing 19. The end of the latch eject lever 18 opposite the bearing 19 gears at the end of the element of lock 13 opposite to trigger heel 20 and push it towards outside under the force of the latch ejection spring 16. Since the locking element 13 is attached to the lock of latch 10 by means of retaining sleeve 14, this one is also shifts out.

Figure 3 shows that, although the lever of ejecting the latch 18 engages in the locking element 13, the force direction of the latch eject lever 18 it is not given by the rotating bearing of the locking element 13 formed by the clamping sleeve 14, so that the lever of ejection of latch 18 exerts a rotating moment on the locking element 13 counterclockwise. Due to this rotating moment both the locking heel is released 15 as the trigger heel 20 of the slot 12.

The door being open (not shown, the latch bolt 10 is in the latch position shown in figure 1, in which the locking heel 15 grab behind the strip 4 (not shown) preventing continue to scroll out.

When the door is slammed or pressed, the strike 33 (figure 3) causes latch bolt 10 to be enter in the additional closing box.

When the door is in its closed position and latch bolt 10 aligns with latch opening 21 of the striker 33 of the door frame, the ejector lever latch 18 pushes latch bolt 10 fully retracted outside the additional closing box 3. Simultaneously to this pushing movement out, the locking element 13 rotates in counterclockwise around the cap of holding 14. When doing so, trigger heel 20 comes into contact with the edge turned towards him from the opening of latch 21 of the strike 33, whereby the locking element 13 is introduced into slot 12 against the moment of rotation to the point where the locking heel 15 can slide past the strip 4. this mode releases the latch bolt 10 from its position of latch and can exit to the bolt position represented in the Figures 2 and 3. In this bolt position, the latch bolt 10 leaves the additional closing box 3 between 10 and 15 mm more than in the latch position according to figure 1.

As seen in Figure 2, the tail of the latch 22 has a protrusion 23. It can also be seen in the Figure 2 that a latch lock lever 25 is housed from rotating shape around a bearing bolt 24 and which is under the pressure of a spring of the lock lever 26 in shape spring arm counterclockwise. When latch bolt 10 is fully extended according to figures 2 or 3, that is, in the bolt position, a locking edge of latch 27 grabs the shoulder 23 behind. Although between the projection 23 and the locking edge of the latch 27 there may be a slight distance, as represented in the Figure 2, the locking edge of the latch 27 grabs in the path of projection displacement 23.

If latch bolt 10 is now inserted in the additional closing box 3 by means of a tool or similar, the projection 23 abuts the locking edge of the latch 27 and prevents further insertion. Latch bolt 10, therefore, is locked in its interlocking position preventing its introduction.

If the coupling bar 11 is rotated a latch recoil lever 28, which with one arm 29 makes contact with the free end of the tie rod 11 and with the other arm 30 makes contact with another projection 31 over the tail of latch 22, a heel 32 of the free end of arm 30 engages with a slide 34 of the latch lock lever 25 and lifts it from its interlocking position, in which the edge latch lock 27 subsequently grabs the protrusion 23, to the point where the locking edge of latch 27 leaves the displacement path of the projection 23. In addition, the arm 30 makes contact with the projection 31 and retracts the latch bolt 10 to inside the additional closing box 3 when turning the lever latch recoil 28. When latch bolt 10 is fully retracted in box 3, the door can be opened. Do not However, this retraction of latch bolt 10 only It can be done with the coupling bar 11.

To allow the electric opening of the door, the interlocking device 1, in particular the strip 4, is provided with an opening device 35, represented in Figure 4, composed of a housing 60 of two elements of extruded plastic This housing 60 or its two halves are provided of accommodation holes for a journal 61 or wheel axles toothed 62 of a gear reducer or multiplier, designated in in conjunction with the number 63. In addition, a housing is housed in a housing electric motor 64 that meshes with a conical pinion 66 of one of the sprockets 62 using a tapered wheel 65. Finally, the housing 60 has a housing 67 for a zipper 68 of which a shoulder 69 stands out. With this wheel 69 the bar can be attached coupling 11 (schematically only).

The electric motor 64 can be rotated gear multiplier 63 and shift rack 68. This allows to move the coupling bar 11 and unlock the additional closing boxes 3. The multiplier gear 63 is self-locking, so it is not possible for the bar to coupling 11 shifts automatically. A command unit adequate causes the electric motor 64 to start rotating by means of a impulse. In addition, through the control unit you can reverse the rotation of the electric motor 64 after a selectable interval and move the rack back to the initial position.

In the view represented in figure 5 of the main closing box 2, the lid 5 is removed, so that the closing mechanism can be appreciated. So, for example, you can distinguish the changeable 70 by the closing cylinder 7, gearing on a slider 72 of an arm 73 of a nut plate of control 74 by means of a bolt 71. The slider 72 acts on a movable stop 75 that is attached to a connecting rod 76. The bar coupling 11 is suspended on this rod 76 at point 77. The control nut plate 74 features another arm 78 more, which makes contact with foot 79 of latch 8.

When using the closing cylinder 7, Actuates the change 70 and with it the control nut plate 74 in the clockwise, latch 8 retracts inside of the main closing box 2 by means of the arm 78 and the foot of the latch 79. However, this can also be done by operating the knob nut 6 with a latch not shown in the figure clockwise, bringing the nut of the latch 6 drags the control nut plate 74 in its rotating movement In addition, when the closing cylinder 7 or the handle of the latch 6 moves the slider 72 and by means of it connecting rod 76, whereby the coupling bar 11 is operated.

Figure 5 also shows that the connecting rod 76 has a shoulder 80, formed by a tongue 82 that protrudes from plane 81 of connecting rod 76. In the direction of displacement (arrow 83), adjacent to ledge 80, is located a rivet 84 which, as shown in Figure 5a, is fixed to the change 70. When crank 76 is moved in the direction of arrow 83, the tab 82 makes contact with the rivet 74 and drag the change 70 in the direction of arrow 83, so, as before described, the control nut plate 74 moves in the direction of the hands of the clock and with it the latch 8 is introduced in the main closing box 2. In this way, it can also be retracted the latch 8 by means of the opening device 35 inside box 2 and thereby open the door electrically.

According to the invention, there is also the possibility of activating the opening device by means of a command wireless remote, in particular through the unit command, so that impulse transmission is not essential through wires. Preferably, the remote control is also You can use it to open the door from the outside. There is possibility of combining the door opening device of entrance to homes etc. with the remote control of a car in A single element of command. As carriers of information they can employ infrared light, ultrasound, radio and transmission inductive according to the respondent principle.
