This application is the United States national phase of International Application No. PCT/EP2017/001090 filed Sep. 14, 2017, and claims priority to German Utility Model Application Nos. 20 2016 005 816.6 and 20 2016 005 817.8, both filed Sep. 22, 2016, the disclosures of which are hereby incorporated by reference in their entirety.
The invention relates to a manually operable electromechanical closure, in particular a rotary latch closure (or compression latch), having a mechanical locking device, which blocks manual operation, but which can be electronically triggered.
However, the invention also relates to a locking arrangement for such a closure, in the particular a rotary latch device or rotary bolt tensioning fastener with evaluatable door contact, for controlling a display device such as a LED module.
An electromechanical closure of the abovementioned type is already known from DE 100 17 217 A1. Reference is also made to DE 20 2011 103 840, EP 0945571 A1 and DE 20 2008 003 720 U1.
A Sensor arrangement, which detects the position of the latch of a closure arrangement and outputs a signal, indicating the status of the latch, is known. By way of example, reference is made to the abovementioned DE 20 2008 003 720 U1, and
The object of the invention is to provide an electromechanical closure of the abovementioned type, which offers further control possibilities and in particular is able to indicate the blocking of the closure.
The sensor device shall also be designed so that it can be assembled and fitted with greater ease and flexibility.
Solution to the Object
The object is achieved according to the invention in that a sensor detects the position of the blocking and provides this to a control device for further processing.
This takes place with a sliding shoe, which is to be placed on the locking tongue of a rotary latch mounted in a door, for running onto a sliding ramp supported by the door frame, wherein the sliding ramp and/or the sliding shoe forms a housing with a recess for the insertion of alternatively a magnet or a magnetic field sensor acting in a contactless manner. Thanks to the sliding shoe, the rotary latch has a smooth operation, and in addition an adapter allows placement on the locking tongue and thereby greater flexibility. Here, rotary latches are able to run onto a sliding ramp supported by the door frame, wherein in particular the sliding shoe includes a housing with a recess, for insertion of alternatively a magnet or a magnetic field sensor acting in contactless manner.
According to a development of the invention, the sliding ramp is also provided with a recess for accommodating alternatively also a magnetic field sensor acting in a contactless manner or a magnet.
According to another embodiment again, the sliding ramp has an adhesive surface on the frame side of the housing, with which the housing of the sliding ramp is affixed to the door frame.
Finally, a rotary latch arrangement is also provided, in which the housing of the rotary latch retains a base plate, supporting a LED, together with LED control electronics, which indicates the convergence of the magnet and the magnetic field sensor by means of a light signal, and thus provides an indication of the position of the tongue on the ramp.
According to a development of the invention, the mechanical locking is formed by a plunger extendable by means of a lowering magnet against a spring force, or adjustable by an electric motor, such as a servomotor.
Where a plunger is present, a development is possible in that the closure has a housing with an opening for the plunger, represented by an elongated hole in axial alignment with the rotational axis of the closure.
According to a development of the electromechanical closure, the housing is a printed circuit board with electronics for switching the closure, which also includes the locking and sensors such as, for example, contactless sensors (e.g. read sensors) for detecting the blocking state.
It is beneficial if the housing of the drive unit and the housing of the printed circuit board are combined to form one housing.
It is also beneficial if the tongue of the closure includes a sliding shoe and a ramp. In this case, the ramp can be provided with a magnet, which is detected by a sensor in a sliding shoe, in order in this way to receive a signal on the locking state of the drive.
These show as follows:
A Particularly Advantageous Embodiment
In the sliding ramp 40 there is a recess for accommodating alternatively a magnetic field sensor acting in a contactless manner or a magnet, that is, an embodiment according to
According to a further embodiment, the actuation 18 can also be designed so that the position of the locking unit (tongue 36 or similar) is interrogated resulting in clear conclusions being drawn on the status of the closure. The tongue 36 is then positioned so that a rotation about the longitudinal axis is inhibited and the detection can take place without errors.
According to another embodiment still, the closure unit 46 is combined with the electronics box 48 to form a single housing unit, containing the components, avoiding the need for a division into a latch 46 and bar magnet 48.
Sliding shoe for the tongue 36
According to another embodiment still, a sliding shoe is used for the tongue 36, which works with a sliding ramp 40, mounted in the frame of the industrial cabinet. The ramp contains a magnet 48, see
Opening procedure
The opening procedure takes place as follows:
An enabling process is carried out, to be able to operate the latch 46. Through a permitted medium, by way of example with an RFID card, the access permission is read out and the latch 46 unlocked. The closure can then be operated. In one embodiment, the system statuses can be represented optically by means of a coloured lamp 54.
In place of the rotary latch closure 114, what is known as a compression latch can also be used, in which part of the rotation is converted into an axial movement of the tongue (not shown).
Authorisation unit
For the authorisation unit 144, e.g. for the unlocking entity, by way of example an outdoor antenna 122 is used. This antenna 122 detects (recognises) a learned RFID unit and reads out the values stored in this unit. The data are evaluated by a read unit, which checks the access permission. However, instead of this, a fingerprint sensor can be used to identify the person seeking access, as in the prior art.
According to a further embodiment an authorisation unit 144 can provide a radio module or optionally a unit for contactless energy transmission, as described in a parallel application No 202016003588.7.
Closure unit

The industrial applicability of the invention is in switch cabinet construction.
While several examples of the invention are shown in the accompanying figures and described in detail hereinabove, other aspects will be apparent to, and readily made by, those skilled in the art without departing from the scope and spirit of the disclosure. Accordingly, the foregoing description is intended to be illustrative rather than restrictive. The invention described hereinabove is defined by the appended claims and all changes to the invention that fall within the meaning and range of equivalency of the claims are to be embraced within their scope.
