Definitions

  • the invention relates to an actuating lever of a locking structure according to the preamble of independent claim 1 and a corresponding warning system.
  • actuating levers or locking structures are widely used in doors and windows in a wide variety of designs.
  • an electrical switching device serving to generate a signal as a warning or information device.
  • These devices are usually a hand-operated pushbutton switch easily accessible by the person in the room, which can either be suspended above the bed or on the bedside table, or two similar switches, one of which is on one side of the bed is attached so that a person lying in bed can operate one of the switches with one hand if necessary.
  • Such switches are used to switch on a signal or alarm system that is not in the same room as the bed, so that the person lying in bed can call for help if necessary. For example, this person may wish to be more or less covered in bed, to have a meal or drink, or to receive help getting out of bed or with anything else.
  • the above-mentioned devices require that the persons involved are able and willing to operate the pushbutton switch when needed or necessary. However, this is not the case in many situations because the people do not want a signal to be sent or are unable to operate the pushbutton switch or to think about it. For example, patients may be predisposed to sleepwalking while moving without their realizing it. Or they may have trouble finding their way when they wake up, or in general when it is dark. Certain patients, such as dementia patients, are also regularly unable to remember that they should contact themselves if they want to leave their room for whatever reason or for no reason.
  • floor mats or door rugs which contain one or more electrical switches connected in parallel. The electric switch or at least one of them is activated when the person leaving the room steps on it.
  • floor mats or door rugs have the disadvantage that they only work as expected when they are in the right place, so that the person has to step on them when leaving the room.
  • floor mats or door rugs are not always "ready for use", even if the care staff is very attentive, but are instead cleared away for logistical reasons, for example.
  • the floor mats or door rugs also respond if they are entered by a person or a visitor entering the room. Accordingly, they are usually cleared away when such entry is to be expected.
  • floor mats and door rugs of the known type can cause hygienic problems, as they often have to be cleaned or even disinfected or sterilized, especially in the case of dementia patients, which is not only labor-intensive and expensive, but also requires a manufacturing material with which such treatment is even possible.
  • the object of the following invention is therefore to propose a system that enables an efficient and relatively interference-resistant generation of a warning in a simple and reliable manner when a person leaves a room.
  • An actuating lever for a locking structure has a handle section.
  • the locking structure is designed so that the actuating lever can be moved from a closed position, in which the locking structure is closed, to an open position, in which the locking structure is opened, by means of a pivoting movement.
  • the handle portion of the operating lever can be manually held for pivoting the operating lever from the closed position to the open position.
  • the handle section is in particular equipped with a sensor which generates a signal when the actuating lever is pivoted out of the closed position.
  • the sensor can be arranged in the interior of the handle section, which enables a compact, protected design.
  • the operating lever is preferably designed as a door handle.
  • the locking structure can in particular be a door lock, wherein the door lock may or may not be lockable by means of a physical or electronic key.
  • Door handles are typically L-shaped or, if an analog handle section is provided on both sides of the door, U-shaped, wherein the grip section is designed in the shape of a rod or a tube.
  • the handle section of the door handle can be designed to be aligned quasi horizontally in the closed position and to be tilted or rotated downwards by one of its length for pivoting from the closed position.
  • the term “manually held” in connection with the handle section can refer to the fact that this section can be grasped and thus grasped with one hand. Such a manual holding can also only comprise laying on of a hand for actuation by pressing down.
  • the actuating lever can also be designed as a window handle which is pivoted to open a window.
  • the closing structure can have a spring mechanism which presses the operating lever into the closed position.
  • it can comprise a bolt which, in the closed position, protrudes from the door in which the locking structure is mounted, and which, in the open position, is moved into the door.
  • the latch can also be pressed into the closed position by the spring mechanism.
  • the actuating lever according to the invention can generate a signal when actuated, which signal serves to detect the actuation of the locking structure.
  • this sensor enables the opening of the locking structure, for example to open a door or a window, to be detected.
  • nursing staff or another person can be warned so that appropriate measures can be taken.
  • doors of certain or all patient rooms of a hospital can be equipped with actuating levers according to the invention so that the nursing staff can be warned if the door is opened by a patient, for example at night. In this way, among other things, undesired escape of patients through doors and / or windows can be prevented.
  • the handle section according to the invention enables efficient equipping or retrofitting of the doors and / or windows of those to be monitored Spaces such as patient rooms.
  • Spaces such as patient rooms.
  • the door latches on the outside of the doors of the patient rooms can be replaced by actuating levers according to the invention.
  • a corresponding installation in the rooms themselves is not necessary. It can also be avoided that disruptive installations such as floor mats or door rugs have to be provided in the rooms.
  • the actuating lever according to the invention thus enables, in a simple and reliable manner, an efficient and, in comparison to conventional systems, interference-resistant generation of a warning when a person leaves a room.
  • the operating lever can also be used to prevent a room from being left unnoticed.
  • the sensor of the actuating lever can be any desired sensor with which an inclination or pivoting of the actuating lever from the closed position in the direction of the open position can be determined.
  • the sensor can have an acceleration sensor, a position sensor or gyroscope, a gravitation sensor and / or a similar sensor.
  • the sensor preferably comprises an inclination sensor.
  • Such inclination sensors enable reliable detection of a pivoting of the handle section of the actuating lever. For example, in the case of a door handle, they can efficiently indicate a movement of the handle section from the horizontal.
  • inclination sensors can be designed to be comparatively robust and require little maintenance.
  • the actuating lever preferably comprises a radio transmitter which is designed to send the signal generated by the sensor.
  • a radio transmitter By means of such a radio transmitter, the signal generated by the sensor can be efficiently sent to a target where it can be received and evaluated. With such a radio transmitter it can also be avoided that a fixed installation is necessary for the transmission of the signal.
  • the actuating lever can also be equipped with a warning device which is activated when the signal is generated by the sensor.
  • the warning device can, for example, be a visual one Include warning means such as a warning light and / or an acoustic warning means such as a loudspeaker.
  • the sensor preferably comprises a switch which closes a circuit when the operating lever is pivoted from the closed position.
  • the sensor can enable the signal to be reliably generated in a comparatively simple manner when the actuating lever is actuated.
  • the signal can be represented by a current flow that is generated by the closed circuit.
  • the actuating lever is designed as a door or window handle, it preferably comprises a position switch which, when the handle section is rotated by approximately 180 °, places the sensor in an associated orientation. In this way, the sensor can be adjusted as required to how it is mounted on the locking structure.
  • the decisive factor is on which side of the door the handle section is mounted. If the handle section or the locking structure is mounted on the door on the left, the sensor must be set in such a way that it responds when the handle section is pivoted clockwise. In contrast, when the handle section or the locking structure is mounted on the door on the right-hand side, it must respond when the handle section is pivoted in the counterclockwise direction.
  • the position switch enables such an efficient setting of the desired direction of rotation.
  • the position switch can be designed to rotate the sensor by 180 ° around a longitudinal axis of the handle section, in particular if the sensor is an inclination sensor or includes one.
  • the actuating lever preferably comprises an on / off switch.
  • the on / off switch or activation switch can be coupled to the sensor so that in a switched off state the sensor does not generate a signal when the actuating lever is pivoted out of the closed position.
  • the on / off switch can also be coupled to the radio transmitter so that no signal is sent even if the actuating lever is pivoted out of the closed position.
  • a warning system comprising a locking structure with an actuating lever, wherein the The locking structure is designed so that the actuating lever can be moved from a closed position in which the locking structure is closed by a pivoting movement into an open position in which the locking structure is open.
  • the operating lever has a handle portion that can be manually held for pivoting the operating lever from the closed position to the open position.
  • the handle section is equipped with a sensor that generates a signal when the operating lever is pivoted from the closed position.
  • the closing construction of the warning system can include the properties and features described above in connection with the actuating lever.
  • the actuating lever of the locking structure can have the properties and features described above in connection with the actuating lever.
  • the warning system preferably comprises a radio receiver, the actuating lever being equipped with a radio transmitter which is designed to transmit the signal generated by the sensor, and the radio receiver is designed to receive the transmitted signal.
  • the radio receiver is preferably designed to transmit the received signal to a warning system.
  • the warning system can, for example, be a conventional type of call system, as is often used in hospitals or nursing homes. Such a radio receiver enables the warning system to be efficiently integrated into an existing infrastructure, so that existing systems can also be used to monitor door and window operations.
  • Fig. 1 shows an exemplary embodiment of a warning system 1 according to the invention.
  • the warning system 1 has a locking structure 2 which comprises a fitting 21 equipped with a keyhole 22 and an actuating lever 3.
  • the actuating lever 3 has a quasi L-shaped cross-section like a door trap, the longer leg being tubular, for example made of metal or wood, as a handle section 31.
  • the operating lever 3 is shown in a closed position in which the handle portion 31 is oriented horizontally.
  • An inclination sensor 32, a circuit 33, a radio transmitter 34 and a battery 35 are arranged in the interior of the handle section 31, which is shown partially visible in the figures but is typically enclosed and covered by the handle section 31. On its right side, the inside of the handle portion 31 is closed by a plug-shaped position switch 36 from.
  • the inclination sensor 32 comprises an electrically conductive, for example metal, ball 321.
  • the ball 321 is mounted in a sensor housing in such a way that its position is changed when the handle section 31 is pivoted or inclined. In the closed position of the operating lever 3, in which the handle section 31 is arranged horizontally, the ball 321 of the inclination sensor 32 is spaced from the circuit 33.
  • the circuit 33 connects the battery 35 as a power supply to the radio transmitter 34.
  • the locking device 2 is mounted on a left side of a door of a patient's room, for example in a hospital or a nursing home. It comprises a bolt which, in the closed position, lies in a receptacle in a door frame and in this way locks the door. To ensure that the door cannot open by itself without actuating the actuating lever 3, the locking construction 2 is equipped with a spring mechanism that pushes the bolt to the left into the door frame and the actuating lever 3 into the open position or into the horizontal .
  • the operating lever 3 is pivoted downward to open the door.
  • the handle section 31 is rotated downwards in a clockwise direction around its left longitudinal end.
  • the ball 321 of the inclination sensor 32 is moved downward to the left in the direction of the circuit 33 until it hits it.
  • the circuit 33 is thus closed and the radio transmitter 34 is supplied with power from the battery 34.
  • the ball 321 thus forms a switch which closes the circuit 33 when the operating lever 3 is pivoted from the closed position.
  • the radio transmitter 34 transmits a radio signal 341 which is received by a radio receiver 4 of the warning system 1.
  • the radio receiver 4 feeds the signal into a call system of the hospital or nursing home.
  • the call system informs a carer 5 or another person that the Operating lever 3 was moved from the closed position and thus the associated door could have been opened.
  • Fig. 3 the grip portion 31 of the actuating lever 3 is shown from its open longitudinal end. It can be seen that this longitudinal end is equipped with an on / off switch 37.
  • the circuit 33 can be interrupted via the on / off switch 37 so that the radio transmitter 34 is not active. In this way, the warning system 2 can be activated and deactivated for a specific door.
  • the actuating lever 3 can be located on an outside or corridor side of the door.
  • the inclination sensor 32 works correctly together with the radio transmitter 34 regardless of whether the actuating lever is mounted on the left or right side of the door or on the inside or outside of the door, the sensor 32 can be rotated 180 ° around a longitudinal axis by means of the position switch 36 of the handle portion 31 can be rotated around.
  • the position switch 36 is coupled to the inclination sensor 32, so that a rotation of the position switch 36 simultaneously rotates the inclination sensor 32.
