Description

Catching device for a door

The invention relates to a door closing device for a door with a movable door frame mounted on a fixed door frame.

In the following some definitions of terms are given:

The term "door-closing device" in the present application is to be understood as a device which is accessible via an energy store, e.g.

Return spring, or a foreign-powered motor, e.g. electric engine, the door closes. The term "door closing device" is understood to mean not only a closing device of a door, but also a gate, a window and / or another closure device with a movably mounted wing, that is to say the term "door" in the present application also means a gate, a window and / or another

Locking device understood with movably mounted wing. The term "door opener" or "remotely operated door opener" is in the

to understand the present application as "remotely operable

Locking device for a door. The locking device has a

remotely operated locking device and a door opener latch on. The

output side blocking member of the locking device interacts with the door opener case indirectly or directly together and switches the door opener trap in a blocking circuit and a release position. Locked position means that the door latch is blocked and therefore the door can not be opened. Release position means that it is released and the door can be opened.

Under door opener not only the opener of a door, but also a gate, a window and / or other closure device is understood to be movably mounted wing. That is, the term door is understood in the present application, as stated above, also a gate, a window and / or another closure device with movably mounted wing. But door opener does not mean that an aggregate must be provided to drive the opening movement of the door; however, such an aggregate can be used as an option

be provided.

The term wing or door is understood in the present application, a rotary wing and / or a sliding sash consisting of one or more such wings. It may also be a non-walkable, comparable closure device in the construction or furniture sector, such as a smoke damper. The term lock latch in the present application is understood to mean the latch cooperating with the door latch. It is spring-mounted. It does not have to - but can - be arranged in conjunction with a lock.

As far as the state of the art is concerned:

There are known door closers, which are designed as so-called spring bands (DE 203 00 385 IM, GM 77 30 284). These are hinges with which the door leaves are rotatably mounted on the door frame. The bands incorporate a mechanical return spring which is tensioned when the door is opened and releases energy to close the door, i. the door closes automatically under the action of the restoring force of the spring. A disadvantage of these spring bands is that relatively strong springs are required to ensure complete closing of the door. It is particularly critical when closing the door a latch or a seal

must be suppressed. With the strong springs, the door slams more or less loudly when closing. In addition, when opening a relatively high opening resistance for the user, who opens the door manually.

There are also known hydraulic door closers, in which in one

Door closer housing a closer spring, a hydraulic

Damping device and a closer shaft are stored (DE 28 19 334 A1). The door closer housing is to be mounted on the door leaf or on the door frame. A coupled to the closer shaft force-transmitting linkage is with its free end on the door frame or on the door to fix. With such hydraulic door closers is a muffled

Closing movement of the door over the entire door opening area up to the closed position possible. However, the disadvantage is the relatively high

Opening resistance for the user who opens the door manually. Furthermore, resulting in the overlying mounting of the door closer housing optical disadvantages. While there are also hydraulic door closers for concealed inboard mounting, i. in the door leaf and in the door frame, known. In these embodiments, however, results in a particularly complex installation and there are special structural conditions

required.

Figure 1 shows an example of an embodiment of the

Locking device according to the invention. The installation is realized on a door with a door leaf TF, which is rotatably mounted on a fixed door frame TR about a vertical axis of rotation.

The locking device according to the invention is composed of two locking components in the installation example. The one closing component is formed by two spring strips FB, via which the door leaf TF is mounted about its vertical axis of rotation. The other closing component is formed by a special door opener TO. This door opener has an electrically operated motor-driven closing unit, which detects the door leaf shortly before the closing position of the door by means of a driven-side catching element and pulls it into the closed position by a motor. The inserted spring strips FB are ansich known commercial

Spring hinges. They each have a mechanical spring unit, which is integrated in the bands and forcibly charged when you open the door and when closing the stored energy returns to drive the door automatically in the closing movement. Such spring bands are z. B from DE 203 00 385 U1, GM 77 30 284 known.

Instead of the spring bands can also be another closing means, for. B. a ansich known hydraulic door closer with closing spring, hydraulic damping and force-transmitting linkage. Such a door closer is z. B. from DE 28 19 334 A1.

The main advantage of this new system is that the first

Locking component may each be designed as a very simple locking unit, which preferably has only low opening resistance and only has to be designed so that the door from the open position

is reset to near the closed position. The subsequent closing of the door in the closed position, optionally by overpressing a latch and overcoming a door seal is ensured by the second locking component, in the case shown by the motorized Zuziehaggregat the door opener TO. There are also embodiments possible in which the Zuziehaggregat not connected to a door opener, but is designed as a separate closer unit without door opener function. A separate door opener may or may not be present in any case.

FIGS. 2 to 13 show various embodiments of this second locking component, i. Embodiments of the

Zuziehaggregats. These cinching machines can also be used at the same time

Have door opener function, i. even act as a door opener, namely, if the motor-operated catch element F in the closed position of the door in the locked position can be determined, which may optionally be realized by the self-locking of the motor drive unit. Both

Exemplary embodiments of FIGS. 3 to 13 are

Inventive embodiments. These are the wing-side

Ggenelement R designed as a spring-mounted überdrückbare door opener trap. In the embodiment of Figs. 2aa to 2cb is the wing-side

Counter element R designed as a rigid mushroom head. Figures 2aa to 2cb are only for a better understanding of the Zuziehaggregats in conjunction with the door positions when closing the door, which also in the

be traversed embodiments of the invention. Figures 2aa to 2cb show the embodiment of the Zuziehaggregats in

different door positions, each with a schematic

Sectional view and a schematic side view are shown. Figs. 2aa and 2ab show a first embodiment, in which one to a

Rotary axis FS rotatable catch element F is disposed in the door frame TR and cooperates with a arranged on the door leaf TF counter element R. Trained as a flat pivot arm catch element F is at his

Storage end rotatably mounted about a rotational axis FS and has at its free end two parallel prongs FZ. The tines FZ extend in the longitudinal direction of the pivot arm and are substantially radially to

Facing axis FS aligned. They have different lengths, in such a way that when closing first with the counter element R coming into engagement tines FZ is shorter than the subsequent closing of the door then with the counter element R coming into engagement prongs FZ. The catch element F is rotatably connected to the output shaft of a motor assembly M and rotatably driven in this manner.

The counter element R is rigidly mounted immovably on the door TF. It is designed as a mushroom plug. The bolt is designed as a cylindrical pin and the mushroom head as a flat disc. The diameter of the pin is smaller and the diameter of the disc is greater than the clear distance the two tines FZ.

In the door position shown in Fig. 2aa and 2ab, the door TF is just before the system on the door frame TR. The catch element F assumes such a rotational position that the pin of the counter element R is able to submerge between the two prongs FZ of the catch element F. There is still no engagement between the catch element F and the counter element R.

In the door position shown in Fig. 2ba and 2bb of the door TF is still closed by a few degrees more. The counter element R just comes into engagement with the counter element R and dips between the tines FZ of Fangelements F. The pin of the counter element R comes initially to the inside of the longer tines FZ to the plant. The shorter tine FZ is overrun. At the same time the motor unit M is turned on, which now causes the catch element F in rotation. The motor unit M now acts as a closing aid. The door leaf TF is further closed under the driven pivoting movement of the catch element F in engagement with the counter element. As part of the pivoting movement of Fangelements also the inside of the shorter tine on the pin of the counter element R comes to rest. The pin further immersed in further rotation in the distance space between the two tines of Fangelements F, taking with it the door TF, which is brought into an Endschließposition, which is shown in Figs. 2ca and 2cb. In the final closing position, the door panel TF is fixed to the door frame TR.

The motor unit M may preferably be an electric motor. The rotational movement of the motor unit M can by a be triggered electrical contact, for example, by the

Counter element R and the catch element F may be formed. It may be provided a corresponding switch means, for. B. arranged between the tines FZ. But it can also be provided a switch which is arranged on the door frame TR and is operated directly by the door leaf TF. The shutdown of the motor unit M can be done for example by an overcurrent switch or by a limit switch, if it is an electric motor. It may also be provided that the motor unit is an electric geared motor, wherein the gearbox may preferably be a reduction gearbox which reduces the rotational speed of the rotor.

In the second embodiment shown in Fig. 3a to 3c, a catch element F is provided, which is mounted linearly movable on the door frame, parallel to the longitudinal extent of the spar of the door frame TR linearly movable. The catch element F is connected to the output of the motor assembly M. It has at its free end on a hook-shaped end portion, wherein the hook claw perpendicular to the spar of the door frame TR

is arranged and protrudes with the door open TF from the opening plane of the door frame TR. The counter element is designed as a lockable latch S when the door leaf TF is closed. The lock latch S is mounted on a spring in a housing mounted in the spar of the door leaf TF and has a slope coming into effect when the door leaf TF is closed. The catch element F has a rounded bevel, which interacts with the inclination of the latch S when the door leaf TF is closed. When closing the door leaf TF (Fig. 3a), the bevels of the

Fangelements F and the lock trap S from each other, the

spring-loaded latch S falls back into the lock and finally engages under the hook claw of Fangelements F (Fig. 3b). The hook claw of Fangelements F is now retracted by pressing the motor unit M linear to the door frame TR and takes the lock latch S along with the door TF, whereby the door TF finally comes to rest on the door frame TR (Fig. 3c) and thus the Closed position of the door is set.

For actuating the motor unit M, not shown

Switch devices may be provided. They may be formed, for example, like the switch arrangements described above in connection with FIGS. 2aa to 2cb.

Figs. 4a to 4c show a third embodiment of the

Door locking device. The catch element F is pivotally mounted about a rotational axis FS parallel to the longitudinal extent of the spar of the door frame TR and is rotationally rigidly connected to the output of a motor unit. The engine assembly is not shown in Figures 4a to 4c, but can

be designed accordingly as the motor unit M in the

Embodiment in Figure 1. The catch element F is in the

Embodiment arranged in a recess in the spar of the door frame TR. The catch element F is in the manner of a pivoting latch of a

Door opener trained. It has at its end facing away from the axis of rotation FS two tines FZ, wherein the spar of the door frame TR facing tines FZ with the door open from the spar of

Door frame TR, that protrudes from the recess of the door frame TR ₁ . The other tine FZ is shorter. Between the two prongs FZ a trigger FA is arranged, which actuates the motor unit M. When the door leaf TF is closed, the latch S is inserted into the recess of the door frame TR and actuates the trigger FA (FIG. 4b). Now, the catch element F is rotated, wherein the tines FZ facing the spar of the door frame TR engages over the latch bolt S and thus takes the door leaf TF against the door frame TR (FIG. 4c).

Fig. 5 shows a fourth embodiment of the door closing device. The catch element F is substantially sickle-shaped, d. H. as a circular disc with a circumferential recess. Comparable like that

Catching element F in Figure 4 is also the catch element F is pivotally mounted in Figure 5 about an axis of rotation FS parallel to the longitudinal extent of the spar of the door frame TR and is rotationally rigidly connected to the output of an engine unit, not shown. When closing the door leaf, not shown in Fig. 5, the lock latch engages in the peripheral recess of Fangelements F and is overlapped when turning the F catch F through a hook-shaped portion of the F F and taken away. The embodiment shown in FIG. 5 is characterized by a particularly simple construction.

Fig. 6 shows a fifth embodiment of the door closing device. In this case, the catch element F is designed so that it is pivotable on the one hand about an axis of rotation FS arranged parallel to the door opening plane and on the other hand in a plane of movement perpendicular to the plane of rotation

Door opening plane is arranged, is linearly displaceable. The catch element F is rotatably connected to the output of a motor unit not shown in Fig. 6. The catch element F and the motor unit M are in a bearing recess arranged in the spar of the door frame TR. The catch element F has a hook-shaped end portion, wherein the

Hook claw is arranged perpendicular to the spar of the door frame TR and with the door open TF (not shown in Fig. 6) from the surface of the door frame TR, i. from the bearing recess, protruding. The catch element F is in the open position of the door in an inclined position, so that the hook-shaped end portion is outside the movement of the lock latch.

When closing the door, the engine unit M is first actuated. The catch element F is as far as swung out of its inclination under the action of the motor assembly M, so that it is a position in the

Movement path of the latch takes. From this position, the catch element F is linearly displaceable in a plane of movement perpendicular to the door opening plane. When closing the door, the engagement position of catch element F and latch S takes place by the catch element F with the

Pivoting with its hook-shaped end portion engages over the lock catch, not shown in FIG. 6. The catch element F then takes in its linear displacement, the latch together with the door with, until the door rests on the door frame and thus the door is in the closed position.

Figs. 7a to 7c show a sixth embodiment of the

Door closing device, in which the catching element is formed from two sub-elements FL1 and FL2, which are arranged at a distance from each other and movable in opposite directions to each other. They are mounted on the door frame TR so that in the closed position of the door (Fig. 7a) on both sides of

Door leaf-side latch S are arranged. The two sub-elements FL1 and FL2 are linearly movable toward each other and each have a slope, which come to rest on closing latch of the door TF on the latch S and take the latch and thus pull the door TF. On the two slopes, a force amplification can occur analogously to the force relationships on a wedge, so that only a comparatively small force has to be provided by the motor assembly not shown in FIGS. 7a to 7c in order to produce a high closing force on the door leaf TF. Figs. 8a and 8b show a seventh embodiment of the

Door locking device. It differs from the example shown in FIGS. 7a to 7c only in that instead of being linear

movable subelement pivotable subelements FS1 and FS2

are provided, which are rotatably mounted. They come when closing the door with the door leaf-side latch S in engagement and take in their driven rotary motion the latch S with. This will be the

Door TF tightened and the closed position of the door made.

FIGS. 9a to 9d show an eighth embodiment.

The door closing device is integrated in a door opener. For this is the

Door opener latch 1 of the door opener specially designed. It will be explained in more detail below in connection with FIGS. 9a to 9d. The door opener latch 1 cooperates with an output member 2 of an adjusting device 200. The

Actuator 200 acts as a motor assembly for closing the door leaf. In addition, the adjusting device 200 also forms the locking device of

Door opener, on which in the closed position of the door, the door latch 1

Door leaf facing side of the case body 10 is arranged and the pivot axis of the locking lever 10h is aligned parallel to the pivot axis 110s of the bearing body 110. A first end portion of the lock lever 10h is formed as a stopper end 10a and cooperates with the lock catch 90. A second end portion of the locking lever 10h is formed as a locking ring end 10e, and cooperates with sawtooth-shaped latching recesses formed on the latch body 10. In a between the abutment end 10 a and the pivot axis of the locking lever 10 h section is between the locking lever 10 h and the

Case body 10, a compression spring 10r arranged, which presses the locking engagement end 10e on the case body 10. The locking engagement end 10e may slide along an arcuate release stop 10f when it stops is engaged with the sawtooth recesses.

On the underside of the latch body 10 facing away from the door leaf, a wedge surface 10k is formed on the latch body 10 which cooperates with the output member 2 of the control device 200.

9a now shows the device in a first position, in which the lock catch 90 has not yet come to rest on the wedge surface K of the driver 10m of the case body 10. The case body 10 is locked on the bearing body 110, because the locking engagement end 10e of the locking lever 10h engages in one of the sawtooth-shaped latching recesses of the bearing body 110.

When closing the door leaf (see FIG. 9b), the latch 90 comes into contact with the driver 10m and thus triggers the drive of the adjusting device 200 via a switching device, not shown in FIGS. 9a to 9d, whereby the output member 2 into the actuator 200th moves back and the door opener latch 1 is pivoted in the closed position in Fig. 9b. It can be provided that the lock latch 90 is suppressed before it falls behind the driver 10m, as shown in Fig. 9b. The door opener latch 1 is only pivoted so far that the latch 90 in this position of the door still has a small distance to the top of the stop end 10a of the locking lever 10h.

Then, the output member 2 of the actuator 200 is operated again and now pivots the door latch 1 in its horizontal position in Fig. 9c back. In this case, the locking lever 10h is pivoted so far that it comes out of engagement with the locking recesses of the bearing body 110. The at the

Locking lever 10h attacking compression spring 10r is dimensioned so that the Lock latch 90 is not overridden in the pivoting of the locking lever 10h (Fig. 9c).

Now, the case body 10 is released again, so that the output member 2 of the actuator 200 when sliding along on the wedge surface 10k of the case body can push back the latch body 10 in the direction of the pivot axis 110s. In this case, the door leaf is taken over the latch 90 until it rests against the door frame, not shown in Fig. 9a to 9d and the closed position of the door is made. In the closed position of the door a vibration-proof system of the case body 10 is obtained at the lock latch 90.

It is envisaged that the adjusting device 200 also works as a locking device, which prevents the mounting of the door leaf. Upon release of the

Door opener latch 1 can either be provided that the adjusting device 200 withdraws the output member 2 or that the output member 2 can be over-pushed. In both cases, the positions shown in FIGS. 9a to 9d are traversed in reverse order, that is to say in FIG. H. starting at the position shown in Fig. 9d up to the position shown in Fig. 9a.

The adjusting device 200 thus forms a device for closing the

Door leaf in its closed position. At the same time it forms a device for self-adjustment of the door latch 1, by the device ensures that the door latch 1 is automatically placed in the closed position of the door in a vibration-proof contact with the latch 90. When opening the door, the positions in the order of Fig. 9d, 9c, 9b, 9a to go through. When closing the door, the position in the

Sequence of Fig. 9a, 9b, 9c, 9d go through. Figs. 10a to 10d show a ninth embodiment, wherein

Means substantially as the device shown in Fig. 9a to 9d is formed, with the difference that further

Lock latch actuating body 110b is provided and that the bearing body 110 is not pivotable, but is fixedly arranged on the housing 6. The lock latch actuating body 110b has a straight front surface and an oblique rear surface. The straight front surface of the lock latch cooperates with the inclined surface of the door latch when closing to the

Lock latch when closing to overpressure. The oblique rear surface of the latch acts on opening the door with the rear straight portion of the latch 90 together to the latch 90 when open to

About pressures. When closing the door, the positions in the order of Fig. 10a, 10c, 10d to go through. When opening the door, the positions in the order of Fig. 10d, 10c, 10b, 10a to go through. FIGS. 11 to 13 now show an exemplary embodiment of the adjusting device 200.

FIG. 11 shows an actuating device 200 on a hydraulic basis. The

Output member 2 is formed as a working piston 2k of a piston-cylinder device 20 which is connected via a magnetic check valve 5 with a hydraulic pump 220. The check valve 5 has a valve tappet with three

Switching chambers, which are arranged one behind the other in the longitudinal axis of the valve stem. Further, a hydraulic spring storage device 30 is provided, which via the check valve 5 also with the hydraulic pump 220th is connectable. The hydraulic pump 220 generates the required operating pressure in the hydraulic circuit.

In a first position of the check valve 5, the compounds of the piston-cylinder device and the spring memory device 30 with the

Hydraulic pump 220 interrupted. The output member 2, d. H. the piston of the piston-cylinder device 20 is locked against the impressions in the cylinder. Consequently, the door latch 1 is locked. In a second position of the check valve 5, the hydraulic pump 220 is connected with respect to the output member 2 in the printing operation. When the pump 220 is turned on, the driven member 2 is pushed out of the cylinder. When the hydraulic pump 220 is switched off when pushing the output member 2 into the cylinder of the piston-cylinder device 20, the spring of the spring-loaded device 30 is tensioned, so that the output member 2 is pressed under the action of the spring in the direction of the cylinder of the piston-cylinder device, if it is not or only slightly charged.

In a third position of the check valve 5, the hydraulic pump 220 is connected with respect to the output member 2 in the suction mode. Consequently, that will

Output member 2 in the cylinder of the piston-cylinder device 20 in

Pulling release position and at the same time stretched the spring of the spring memory device 30. 12 shows a second embodiment of the locking device 200. An electromechanical rotary motor 230 drives a Schraubspindelgetriebe 235, the output member in the manner of a spindle nut on the screw continuously a linear movement along the longitudinal axis of the output shaft of the Rotation motor 230 performs and has a Z-shaped guide curve 236. The driven member 2 of the adjusting device 200 is guided linearly as a piston in the cylinder and has at its lower end portion a roller which rolls in the guide curve 236. The two end portions of the guide cam 236 are directed perpendicular to the guide straight line of the output member 2 and connected by an inclined guide portion. Due to the directed perpendicular to the guide straight line of the output member 2

End portions of the guide curve 236 is a

self-locking cam gear, wherein the screw 235 is a self-locking gear. Consequently, when the power is interrupted, the door opener latch 1 is locked in any position.

In the embodiment shown in Fig. 13, a pawl transmission for moving the driven member 2 is provided.

A first rotatably mounted spring-loaded lever 21 is formed as a pawl and cooperates with the output member 2 of the actuator 200 together. The lever 21 is pressed by a leg spring 21 against the rear circular arc-shaped end portion of the driven member 2.

A second rotatably mounted spring-loaded lever 22 is arranged at an angle to the first lever 21 and has on the lever 21 facing the longitudinal side of a circular arc sawtooth-shaped switching portion, in which the pawl portion of the lever 21 engages. Between the pivot bearing remote from the end portion of the lever 21 and the inner wall of the housing of the adjusting device, a compression spring 22 f is arranged, which at the

Inner wall of the housing facing longitudinal side of the lever 22 engages. On the opposite longitudinal side of the lever 22 is a solenoid 240 arranged, whose longitudinal axis with the longitudinal axis of the

Coil compression spring trained compression spring 22f is aligned and the linearly movable output member rests on the lever 22. The recesses of the sawtooth-shaped switching portion of the lever 22 have a shape congruent with the switching portion of the lever 21, and are directed so that the driven member 2 can not be pushed back, that is, the output member 2 can not be pushed back. H. is not lowered. The output member 2 is thus locked in one direction. The output member 2 is unlocked by operating the solenoid 240, wherein the switching portion of the lever 21 for the operating period out of engagement with the sawtooth-shaped switching portion of the lever 22 passes.

The lever 21 is in each case a tooth in the direction of the output member 2 further switches upon short-term actuation of the solenoid 240, wherein the

Working capacity of the output member 2 is determined by the spring force of the leg spring 21f. With long-term actuation of the solenoid 240, the leg spring 21f moves the output member 2 until the closed position of the door is reached, as described above in Fig. 9a to 9d. The leg spring 21f thus acts as a servomotor, here as a spring motor.

It is also possible that with the described device only one

Locking device is formed. In this case, it is important that the spring force of the compression spring 22f, taking into account the lever ratios and the spring force of the leg spring 21f is so small that the leg spring as long as the first lever 21 presses out of the recess - wherein the second lever 22, the compression spring 22f squeezes until the lever 21 abuts against the actuator 2 and thereby falls into one of the recesses. Like next Run above, so that the actuator 2 is locked until the solenoid 240 pivots the second lever 22 in the direction of the compression spring 22f and the first lever 21 falls from the recess.
