Description

The present invention relates generally to a device for detecting the state of a door, a gate, a window or the like, as well as a method for mounting the device.

BACKGROUND OF THE INVENTION

In the following, reference will be made to the non-limiting example of a door closing device. All subsequent embodiments apply mutatis mutandis to any closing devices for gates, windows, and other devices with which an opening in a building wall or structure can be closed and released or opened.

Often, information about the current state of doors is required, such as whether a door is closed or not (i.e., partially or fully opened), and / or whether a door closure device is locked or unlocked. Such information may be used, for example, in monitoring and securing buildings. For example, fire or smoke protection doors must not be left open in order to be able to fulfill their function. If they do, alarms should be automatically triggered.

To detect the condition of doors, so-called closing state detectors are known which provide signals indicating whether a door is closed. For this purpose z. B. a arranged in or on the door frame or -stock mechanical signal transmitter (eg., A switch) is used, which is actuated by the latch or the latch of a door lock when the door is closed or when the door lock is locked with the door closed , In the case of actuation of the signal generator by the latch can also be concluded from a signal of the closing state detector, whether the door lock is locked or not. Disadvantages of such known approaches include, for example, the effort required for adjusting the closing state detector, the use of a separate component, namely the closing state detector, and its generally complex arrangement in or on the door frame or floor.

The DE 30 25 730 C2 discloses a device with which it can be detected whether a door is closed. The device is arranged in the door frame behind the lock block.

In the patent DE 10 2010 018 566 B4 The present applicant describes a status detecting device for a door, gate or the like in the form of a forend screw. Preferably, the cuff-screw-shaped state detection device does not differ externally from a conventional cuff screw and therefore can be used like this without the need for modifications of a lock or lock cylinder.

Electronic locking devices, in which the locking mechanism and the authentication are not housed in a lock cylinder, but in a fitting (so-called fitting solutions) are also known. Here, for example, can be dispensed with a lock cylinder. The opening in the lock or lock case, which is provided for receiving the lock cylinder, can be used for the accommodation of bracing or fastening elements with which the fitting is attached to the door leaf, or simply remain empty. In other words, due to a non-existent lock cylinder no forend screw is required for the attachment of a lock cylinder.

A preferred object of the present invention is to overcome disadvantages of known approaches for determining whether a door, a gate, a window or the like is closed, and in particular to provide solutions which are substantially completely integrable in a closure device. In addition, the solution according to the invention should be easy to assemble and disassemble.

SUMMARY OF THE INVENTION

The device according to the invention and the method according to the invention are defined by the features of the independent claims. Advantageous embodiments emerge from the subclaims.

Preferred embodiments of the present invention or preferred combinations of features of the present invention are described in the following exemplary aspects.

The present invention preferably relates to a device for detecting an opening state of a door, a gate, a window or the like, which is also referred to as a state detection device hereinafter. In particular, the device according to the invention is designed such that it can be used in a lock or a lock case in an existing receptacle, this existing receptacle is preferably intended to introduce a fastener, which serves to fasten a lock cylinder. Specifically, the intended receptacle is an opening for a forend screw or lock cylinder forend screw. As a cuff screw is usually called a screw with metric thread, which has a Locked profile cylinder in the lock case and thus prevents the extraction of the profile cylinder in the installed state. The forend screw is not accessible from outside when the door is closed.

According to the invention, it is not necessary that the state detection device fulfill the function of a fastening means, but only uses the space provided for such a space.

The device according to the invention comprises at least one sensor device for detecting a closed or opened state of the door, the gate and the like. The sensor device may comprise at least one sensor unit. Preferably, each sensor unit comprises at least one of the following components: a Hall sensor, an optical sensor, an inductive sensor, a capacitive sensor, a pressure sensor, a reed sensor, an electric key switch. In the case of Hall sensors, the closed state of the door, the gate, and the like can be detected when a magnetic field interacts with the Hall sensor in the closed state of the door, the door, and the like. Such a magnetic field can be provided, for example, by a magnet or controllably magnetizable element (for example a coil) arranged on or in the door, gate or window frame or frame or strike plate, etc.

The sensor device preferably has a first sensor unit in the form of a Hall sensor in order to detect the closed state of the door, the gate and the like. In particular, the first sensor unit may be designed and / or arranged such that, when the door, gate and the like are closed, it can detect this condition.

Furthermore, the sensor device may comprise a second sensor unit which serves to detect a manipulation. For example, the second sensor unit may serve to detect a magnetic field that is different from the normal magnetic field that exists in a closed door.

Thus, the second sensor unit may be arranged so that it receives no information about the state of the door, the gate and the like, d. H. the second sensor unit may be arranged so that it can not detect the closed state of the door, the gate and the like.

For example, in the case of Hall sensors, the second sensor unit may be disposed in the state detection apparatus such that a magnetic field passing in the closed state of the door, gate, and the like in interaction with the first sensor unit does not interact with the second sensor unit. As a result, z. For example, it may be noted that another magnetic field is used to manipulate the opening state detecting device by, for example, bringing an electric or permanent magnet near the state detecting device to simulate a closed state of the door, gate, and the like, or a magnetic field a portable device unintentionally acts on the sensor units.

However, it is also possible that the second sensor unit is also arranged to detect the closed state of the door, the gate and the like. Such variants may allow a more reliable detection of the closed state of the door, the gate, and the like, for example, when the closed state of the door, the gate, and the like is indicated only when the first and second sensor units have detected or detected the closed state, or if at least one of the first and second sensor units has detected or detected the closed state.

The device according to the invention can preferably be locked easily and preferably without additional tools within the receptacle or opening. The device is preferably insertable into the receptacle in a first insertion state, and is preferably designed so that, when inserted into the receptacle, the device moves into a second locking state in which the device is locked in the receptacle. Preferably, the device is clamped or held within the receptacle.

Preferably, the device is elongated and / or has at least one longitudinal axis and at least two parts which are displaceable relative to each other along the longitudinal axis to move between the two states, i. h., to change the lock state and launch state.

The transition from the introduction state into the locking state is preferably supported by a spring force of a spring. Additionally or alternatively, the spring may also serve to bias the two parts so that only the two states of the insertion state and the locking state are stable when no external force acts on the device. In other words, the device according to the invention is elongated, wherein the front end is inserted into the receiving / opening of the lock and the rear end of the device remains visible in the inserted and locked state from the outside. Preferably, the spring is attached to the first part and exercises the Spring force on the second part, wherein the spring force pushes the second part to the rear. If the second part is at the rear end of the first part, close both parts back preferably flush.

According to another preferred aspect of the present invention, the spring is a leg spring. Leg spring is called a coil spring, which is subjected to bending around its axis. In contrast to hooks or eyes of a tension spring of the spring wire typically ends in lever-like legs, where the torque can be better initiated. Preferably, the two legs of the leg spring engage directly with the receptacle to lock the device in the receptacle.

According to a preferred embodiment, the two parts of the device are made of plastic. According to a further preferred embodiment, a part of the two parts has a ring portion, preferably a closed ring portion, and the second part is preferably displaceable within this ring portion.

In addition, the invention preferably relates to a method for introducing a device according to the invention into a receptacle provided in a lock comprising the steps of: providing a device according to the invention, inserting the device into the receptacle, wherein the device automatically transitions into the locking state.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The 7a and 7b show schematically a lock case 100 with a cuff plate 110 as essentially known from the prior art. The lock box 100 is by means of two screws in the two openings 115 in the cuff plate 110 are introduced, fixed to the door leaf of a door, not shown. In addition, the trap 113 that usually goes beyond the nut 103 is pressed, and the bolt 112 which usually comes with a locking bar 102 a lock cylinder is actuated, shown.

According to a preferred embodiment, the state detection device according to the invention 30 adapted to, in the forend screw hole 111 to be used (see 7b ). Preferably, the state detection device according to the invention 30 without additional aids such as screwdrivers or the like inside the forend screw hole 111 Preferably, the locking is done automatically during the insertion process by the state detection device 30 from a (first) introductory state 31 in a (second) lock state / lock state 32 passes. The terms locking and locking are used synonymously in the present application.

1 shows a preferred embodiment of a state detection device according to the invention 30 in the (first) introductory state 31 , The device 30 is similar to a cuff screw substantially cylindrical, but preferably has a length along the longitudinal axis L, which is preferably shorter than the length of a corresponding forend screw. The diameter of the device 30 along the radial direction R (see 2 ) preferably corresponds to the diameter (M5) of a set screw. This ensures, for example, that the device 30 Just like a chair screw in the opening 111 of the cuff plate can be introduced. According to the invention, the extent in the radial direction R can also be smaller than the diameter of a corresponding set screw.

Preferably, forend screws have a tapered countersunk head which terminates at the conical opening 111 adjusted in the cuff plate. The device according to the invention may have a corresponding conical section 21 having a corresponding diameter, in order to be mounted in a form-fitting manner in the opening 111 in the cuff plate similar to a cuff screw.

1 shows the essential two parts 1 and 2 which can be displaced relative to one another along the longitudinal axis L, from an insertion state 31 in a locked state 32 switch. In other words, the two parts 1 and 2 can be moved or moved translationally in a straight line relative to each other. The second part 2 is in 1 dotted or greyish to better distinguishability. The two parts 1 and 2 are in the 1 and 2 in the introductory supplement 31 , A thigh spring 10 is at the first part 1 so attached, that the two thighs 11 and 12 the feather 10 with the second part 2 engage or press against the second part. The thighs 11 and 12 on the second part 2 applied force F is directed substantially radially outward, so that the spring 10 essentially exerts no force that supports a translation of the two parts to each other. Therefore, the introductory state 31 a substantially stable state.

Preferably, the circular portion of the spring 10 around a thorn 15 attached around, with the spike 15 preferably substantially perpendicular to the longitudinal axis L. The diameter of the spine 15 is preferably smaller than the inner diameter of the circular portion of the spring 10 , Preferably 95% of the inner diameter to always the desired forces of the legs 11 and 12 to enable.

2 shows the device 30 just before they are in the opening or recording 111 is inserted in the cuff plate (see double arrow).

The device 30 is by simply pushing or pushing into the opening 111 inserted so far until the second part, which is preferably similar to a countersunk head, comes into contact with the cuff plate (see 3 ).

By further pressing (see 4 ; Double arrow) on the back end of the first part 1 becomes the first part 1 further into the opening 111 inserted. Because the second part, especially the collar 21 of the second part, which engages the cuff plate and prevents displacement of the second part with respect to the cuff plate, there is a relative displacement (translation) of the two parts 1 and 2 , With the onset of this relative displacement, the direction of the force exerted by the spring on the second part also changes (see vector F on the leg 11 ). The obliquely rearwardly acting force F thus contains, in addition to the radial component, a component pointing backwards, which determines the relative displacement of the two parts 1 and 2 additionally supported each other. The device literally snaps automatically from the insertion state to the locking state 32 of the 5 , The two thighs 11 and 12 The leg spring press against the inside of the faceplate, causing the device 30 inside the opening 111 is locked. The mechanical assembly is finished.

According to the invention, the device should also be easy to disassemble. Preferably, the device has at the rear end of the second part 2 a small recess into which a tip of a pointed object (eg knife tip, tip of a screwdriver) can be inserted, so that via a lever action on the forend plate a force component on the second part 2 can be directed to the outside (back). If this force component is greater than the opposite force of the two torsion springs, the two parts 1 and 2 so shifted to each other that the device out of the opening 111 is removable.

So far, essentially the mechanical components of the device according to the invention have been 30 described for locking. However, since the device according to the invention serves for detecting an opening state of a door, a gate or the like, the device comprises at least one sensor device 50 , The sensor device 50 can be one or more sensor units 51 exhibit. The at least one sensor unit is used to detect whether the door is open or closed.

For example, a small magnet can be attached to a door frame or to a strike plate on the door frame. The magnet can be mounted in any conceivable manner, for. B. simply be glued. For detecting such a magnet is preferably a Hall sensor 51 accommodated in the device according to the invention. Preferably, the Hall sensor is on a small board 50 housed, with the board on the first part 1 the device is attached. Preferably, the Hall sensor 51 mounted on a foil board, whereby the electronics can be easily and safely attached to and / or in the device. Preferably, the Hall sensor 51 mounted in the rear portion of the device, and preferably at the rear end of the device 30 attached (see 9a and 9b ). To safely detect the door in the closed state, even if only a small magnet is attached to the door frame, it is preferable that the Hall sensor 51 only a few mm away from the rear end of the device, preferably at most 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm; preferably less than 1 cm from the rear end.

In addition, also another Hall sensor 52 on or in the first part 1 be mounted so that it does not primarily serve for the detection of the above-mentioned magnet, but also differently oriented detects magnetic fields in the vicinity of the device. The 9a and 9b show similar to the 1 to 4 However, the device according to the invention in a 90 ° rotated about the longitudinal axis side sectional view. The spring is corresponding 10 shown cut. You can also see the board 50 in the form of a foil board extending from front to back along the longitudinal axis, with a cable at the front end 39 is shown, with which the signals of the sensors 51 and 52 to get redirected. The 8th shows in particular the cable 39 as it is from the opening 102 , which is provided for the lock cylinder, is led out to further process the signals of the sensors. The second sensor 52 is also preferably a Hall sensor with the magnetic fields are detected. Preferably, this second Hall sensor 52 but further than the first sensor 51 arranged from the rear end of the device, as this Hall sensor 52 preferably does not serve to detect the magnetic field on the door frame, ie the sensor 52 is not intended to detect the opening or closing state of the door. Rather, this is the second sensor 52 around a "manipulation sensor" with the additional magnetic fields, possibly for manipulation of the sensor 51 could be used to detect. Preferably, this sensor is located 52 at least 5 mm, preferably at least 1 cm from the rear end of the device 30 away. In addition, it is preferred that this manipulation sensor 52 in the device is arranged in a radially outer portion, whereas it is preferred, the first sensor 51 center with respect to the radius. One skilled in the art will recognize, however, that this central arrangement of the first sensor 51 is not necessary with respect to the radial direction and for detecting the door condition, it is only necessary to detect a magnet on the door frame, so that it is advantageous to the sensor 51 in the rear section of the device 30 to arrange.

In the former embodiment, it is assumed that the second Hall sensor is not used to detect the closed state of the door, but to determine whether a closed state of the door detected by the first Hall sensor is actually present. The second Hall sensor is preferably "further in" (farther forward) in (on) the device 30 arranged and thus further than the first Hall sensor 51 spaced from the rear end of the device, which in the closed state of the door opposite to the magnetic field providing detectable element and comes closest. By suitable dimensioning of the magnetic field and / or a sufficient distance of the second Hall sensor 52 from the first Hall sensor 51 can be achieved that the second Hall sensor 52 even in the closed state of the door does not respond to the magnetic field. For this purpose, the second Hall sensor, for example, be arranged at a distance from the first Hall sensor, which is equal to or greater than the distance that has the first Hall sensor in the closed state of the door of the magnetic field providing detectable element. Detects the first Hall sensor 51 the magnetic field of the providing detectable element and becomes the second Hall sensor 52 not actuated by the magnetic field, it is concluded that the door is actually closed. If there is a magnetic field on both Hall sensors 51 . 52 respond, it can be assumed that the magnetic field not from the detectable element, but z. B. by a used for manipulation (permanent) magnet or by an electrical or electronic device that generates a magnetic field, is provided, wherein the magnetic field triggers the two Hall sensors (unintentionally).

An essential preferred advantage of the present invention is the fact that the device is externally modeled on a conventional forend screw substantially and therefore how this can be used in the foreseen screw cap opening, without causing modifications of a lock (ie the existing "infrastructure") required are.

The invention also includes the exact or exact terms, features, numerical values or ranges, etc. when, above or below, these terms, features, numerical values or ranges are used in conjunction with terms such as, for example. For example, "about", "about", "about", "substantially", "generally", "at least", "at least", etc. (ie, "about 3" should also be "3" or "im Substantially radial "should also include" radial "). The term "or" also means "and / or".
