Description

The invention relates to a device according to the preamble of claim 1.

From DE 89 14 737 U1 is a device according to the preamble of claim 1 known.

The housing of this known device, also known as "Vertical Door Guard" is referred to as hood-shaped Slider formed, with the clamping fit on the mounting plate, which is referred to there as the base plate held will and can be moved down when over the door handle exercised a corresponding downward force becomes. In the housing, a locking pin is disposed against the force of a compression spring perpendicular to the direction of movement of the housing is displaceable, in the alarm position, which is taken when the door handle moves down was, in an opening in the mounting plate form-fitting locks. From this position, in which the door is opened can, the locking pin can only with the help of a key be removed from the outside again. Due to the fact that the housing held on the mounting plate with a clamping fit is, there is a risk that this clamping force is too large and the door can not be opened in an emergency, as the Force that the person exerting on the door handle is insufficient to move the case down.

The invention is based on the object, a device to create according to the preamble of claim 1, at which is ensured that in an emergency the corresponding Person can safely open the door, i. the device in the alarm position moves and thereby unimpeded opening the door allowed.

This task is basically characterized by the hallmark of Claim 1 solved.

According to the invention under bias of the compression spring standing locking pin two tasks. One is the light and unhindered on the mounting plate down keep movable housing in the home position and during movement the door handle down, i. in case of emergency one exactly defined, but not really inhibiting force of this movement to oppose and at the same time ensure that that after a certain movement of the door handle down the case falls by itself into the alarm position, in the the housing safely releases the door handle to open the door. This alarm position is positively locked by the locking pin by the corresponding engagement in the opening in the mounting plate secured.

Advantageously, the device is designed to as specified in claim 2. The interaction of the under Preload of the compression spring locking bolt and the Locking recess ensures that the basic position is maintained will that force is needed to help with the door handle to leave this basic position, precisely defined and in any case, on the one hand, not too big and on the other hand, an undesirable slipping into the alarm position prevented. The formation of the opening to the positive Recording the locking bolt as in the direction of movement long stretched rail ensures that the housing when moving from the basic position to the alarm position performs a correspondingly large stroke, the sufficient Movement of the door handle for safe release of the door guaranteed.

When locking pin and locking recess are designed as in Claim 3, then the defined force to Clinging in the basic position, but also to the task of this Basic position accordingly well defined.

In an advantageous manner, between basic position and Alarm setting a pre-alarm position are taken. If a person accidentally or without thinking about it Door handle slightly pushes down, is only the pre-alarm position taken in which the person by an acoustic or another signal is that now an alarm is triggered. If the person then refrains from the final operation of the door handle it is ensured that the device is in the home position resumes and an alarm is not triggered. In this then resumed basic position can then also the Door does not open. Defining this pre-alarm position Different configurations are possible, such as they are defined in claims 5 to 7.

If the training as claimed in claim 7 under protection done, then the pre-alarm is simple and to achieve little complicated. The bellow is as a separate Component mounted on the housing. Its resilient property ensures that the door handle back to the normal position is moved when the pressure exerted on him again diminishes, without the actual alarm position occupied has been. At the same time, it can contain electrical contacts through which the pre-alarm is triggered.

Advantageously, the device is designed in this way as specified in claim 8. The cover and base plate existing housing carries all essential components, in particular the locking pin and this biasing Spring.

When the device is designed as defined in claim 9, then a cylinder lock is available, the different Tasks takes over. This cylinder lock is located is in the lid and is by a corresponding Key operated. On the one hand serves the cylinder lock securing and holding the lid to the base plate. Only if the lock cylinder occupies a certain position, The lid can be removed to allow the base plate accessible with the components arranged on it. Furthermore, the lock cylinder but also the increase of the locking bolt, as with the help of the key the various Positions can be taken. So it's possible to move the key to a certain position and thereby the lid with the base plate in one of the three To move positions. It is also possible, the permanent exposure to loosen and replace the lid with the base plate to move back to the basic position.

The use of an electric motor as specified in claim 10 Make sure the device is also removed from one lying point can be actuated. So if at one recognized elsewhere, that an emergency exists, can by a central alarm of the door handle of the corresponding Emergency exit door to be released.

In the following the invention with reference to the drawing explained in more detail with reference to an embodiment.

The device shown in the drawing is a so-called Vertical door guard, in which the components that the Movement of the door handle 1 lock through this, i. at to be moved down with his movement. It is only one Movement, namely the depression of the door handle required to open the door and trigger the alarm.

In Figures 1 to 4 are three different positions shown. The position in FIG. 1 is the normal safety or basic position. In Fig. 2 was the door handle moves about 15 ° to a pre-alarm position. In this position, the two main components, namely the lid 2 and the base plate 4 already slightly emotional. But they are under tension of a return spring, so that upon release of the door handle 1 again the Basic position is taken.

In the alarm position shown in Fig. 3 has been the door handle moves about 30 ° in an alarm position. In this position, the cover 2 and the base plate fall under gravity, after the pre-alarm position have left, i. Overcome force of the return spring has been.

FIG. 4 shows the permanent open position in the door handle was moved about 35 °.

In the figures 5 to 8 essential components are shown, which are arranged on the base plate 4 and the Ensure receipt and determination of the various positions.

A locking pin 8, which at its front effective end face Conical and conical designed, intervenes in the Basic position in a likewise bevelled detent recess 11 on. This detent recess is formed in a slide 9, which is biased by return springs 10, the when moving from the basic position to the pre-alarm position be compressed.

The locking pin 8 is attached to a toggle lever, the formed by a bolt lever 12 and a lever arm 14 is. The toggle lever is pivotable about a pivot axis 13. On the lever arm 14 engages a compression spring 15 which the Bolt lever 12 with the locking pin 8 in the direction of the Base plate 4 pretensions. The slider 9 and the return springs 10 are arranged in the mounting plate 3 and by a Cover 16 protected and guided.

Looking at Figs. 5 to 8 it is clear that when moving of the door handle down the lid (in the figures 5 8 not shown) is moved with the base plate with. First, the return springs 10 are compressed and it the pre-alarm position (FIG. 6) is assumed. This position is unstable, i. when the door handle is released move all parts back to the basic position. First when the locking pin 8 is due to the inclined surfaces moved upward against the force of the compression spring 15 and slips out of the locking recess 11 and into the running rail 18 of the mounting plate 3 passes, all fall Lower parts and enter the alarm position (Fig. 7). From this position, the lid 2 and on the base plate 4 arranged parts together with this again pushed back to the basic position. This main alarm position can only be done by specialized personnel and in particular as later be changed again with the help of a key.

The permanent open position shown in FIGS. 4 and 8 can only be taken when using the later described Cylinder lock the compression spring 15 is compressed, so that the locking pin 8 is raised and the base plate 4 with moved the lid in the continuous open position shown in Fig. 8 can be. This position can only leave again be, if from the outside by qualified personnel with the help of the profile cylinder lock acted upon the device accordingly becomes.

In Figs. 9 to 12, the various positions of Represented components that are located in the mounting plate 3.

FIGS. 16 and 17 illustrate an electric motor 20, which drives a rack and pinion drive 21 with a wedge surface 22. When the electric motor 20 by a remote control is turned on, the wedge surface 22 is under the bolt lever 12 moves and raises it. This allows the lid 2 and attached to the base plate components the Leave home position so that the door handle released is done without an operation by a person. The corresponding parts fall under gravity downward.

With appropriate operation of the cylinder lock acts this on the operating lever 24 and moves it and dash-dotted lines in FIG. 19. The pivot point is designated 25. A detent 23 is displaceable attached to the operating lever 24. This catch usually holds the lid by snapping behind the Lead 28 firmly. Only when the catch is pulled back, the projection 28 is released. Attacks 29 serve the Attachment for the corresponding wall of the lid 2. On the opposite Side are a projection 26 and a hook 27 for holding the lid. Usually the Cover 2 securely held by the fact that the projection 26 safely is held by the hook 27. The latch 23 secures the lid by attacking the projection 28 on the other Page. Only when the operating lever 24 is pivoted is, the catch is retracted and the lid can be removed.

FIGS. 26 and 27 show an embodiment, in which a reed relay 34 is provided on an electric circuit board 35 is. This reed relay works with a magnet, which lies in a recess of the mounting plate and permanently attached to the door to be secured. If the Device is forcibly torn off the door, that will Magnetic field in the area of the reed relay 34 changed, i. this Relay is activated and an alarm is triggered.

FIGS. 20 to 25 show how the profile cylinder 30 is arranged and how he with his locking nose 31 is used. The profile cylinder 30 is in a holder 32 attached and usually by a screw 33 secured. When the lock cylinder is with his Locking nose 31 in the position shown in Figs. 20 and 23 is located, the basic position is taken. Of the Locking pin 8 is located in the locking recess eleventh

When the lock tab 31 is shown in FIGS. 20 and 23 Position in that shown in Figures 21 and 24 Turned clockwise position, the locking lug slides 31 on a rising inclined surface of the lever arm 14 and pushes against the force of the compression spring 15 after below. As a result, the locking pin 8 is raised and it is possible to change him from the alarm to the permanent open position to move. This is without lifting the locking pin with Help of the lock cylinder not possible. The movement of the basic position in the alarm position is as above described without the action of the lock cylinder. If this alarm is taken but once, can only a legitimate person with the help of a key this Cancel alarm setting, i. a movement in the Make basic position or a move to the permanent exposure carry out.

FIGS. 22 and 25 show how with the aid of Locking cylinder, the decrease of the lid 2 is made possible. Reference is also made to FIG. 9. In this one is the Profile cylinder but not shown.

When the locking lug 31 is rotated counterclockwise so is, as shown in Fig. 25, this acts on an actuating lever 24, and moves it as well as dash-dotted lines shown in Fig. 19 and by the arrows in Fig. 22 indicated. The pivot point of the operating lever 24 is designated 25. A detent 23 is on the actuating lever 24 provided and displaced accordingly. This latch 23 usually holds the lid 2 by snapping behind a projection 28 firmly. Only if the catch 23 is retracted (see Fig. 22), the projection 28th Approved. Attacks 29 are the attachment for the corresponding Wall of the lid 2. On the opposite side there is a projection 26 and a hook 27 for holding of the lid. Normally, the lid 2 is sure thereby held that the projection 26 held by the hook 27 becomes. The latch secures the lid 2 by over attack the projection 28 on the other side. Only if the operating lever 24 is pivoted by the locking lug 31 is the locking lug 23 retracted and the cover 2 can be removed become.

In various figures mounting holes 6 in the Mounting plate 3 shown. These take the mounting screws for fixing the device to the door. The mounting holes 6 are through the base plate obscured, they are therefore in the basic position and also in the pre-alarm position not accessible.

In Figures 28 to 40 is another embodiment the device according to the invention shown in principle is constructed as the one described above Embodiment, however, in terms of determination and intake the pre-alarm position and the required for this Components designed differently. Basically the same Parts with the same reference numerals.

In the second embodiment according to FIGS. 28 to 40 it lacks the under tension of the return spring 10 standing Slider 9, in which the locking recess 11 for receiving the locking pin 8 is provided in the basic position. at The second embodiment, the locking recess 11 is not displaceable, i. it is stationary in the mounting plate 3 intended.

The Voralarmstellung is determined by means of a bellows 40 and taken on the lid (2) below the Door handle 1 is arranged. This bellows is springy, so that the door handle 1, as when viewing the figures 28 and 29 becomes clear, can be moved slightly up and down, without already the alarm position is taken. In the Pre-alarm position contacts in the bellows 40 are closed and trigger a pre-alarm that may prevent the person from push the door handle further down, but him let go, so that he by the spring force of the bellows the Basic position resumes without the alarm position was taken in Fig. 30.

In this embodiment of Figures 28 to 40 are fewer components on the base plate 4, i. in the lid 2 arranged. This makes the device easier, cheaper and more robust.

In both embodiments described above the basic position due to the frictional interaction of the locking pin taken with the locking recess and established. In one embodiment, the detent recess slightly movable with the slider to the Define pre-alarm position. In the other second embodiment the detent recess 11 is fixed in the mounting plate 3. When exceeding a certain force, the by the interaction of the end face of the locking bolt and the detent recess is fixed, the basic position leave and that through the cover 2 and the base plate 4 formed housing falls into the alarm position, in the the locking pin is positively in the track rail 18 and can perform a stroke by the length of the Running track is fixed. The design regarding The intake of the pre-alarm position differs in the both embodiments.
