Definitions

  • the invention relates to a tumbler, a safety device with a tumbler and a method for locking a tumbler.
  • the invention relates to a tumbler in which two bolt elements, which can be displaced between a retracted position and a closed position, act between an actuating part and a tumbler part.
  • a device for a simple closure for the storage compartment of a motor vehicle is from the DE 10 2008 041 724 B4 a device is known in which two rack elements are in engagement with a gear. Locking elements are fixed to the ends of the toothed rack elements. Each toothed rack element is acted upon by a spring in the direction of a locking position, in which the locking elements engage in corresponding recesses.
  • An electromagnet can be activated via an actuating switch, as a result of which the toothed wheel is moved in such a way that the toothed rack elements are moved against the restoring forces of the springs, with the locking elements being movable from a locking position into an unlocking position.
  • a suitcase lock with a spring-loaded locking bolt that can be moved in a lock housing and whose closed position can be blocked by a locking device that is also arranged in the lock housing is disclosed.
  • the case can be locked at two mutually spaced points by means of a lock if two locking bolts are articulated in opposite directions on the crank member diametrically opposite one another and each of which is assigned a locking bolt.
  • a device for locking a pivotable flap of a storage box for a motor vehicle has a closure element, which is mounted parallel to an x-axis and is displaceable relative to the flap a control element for opening the flap.
  • the closure element can be shifted at least indirectly via the operating element into a position releasing access.
  • the closure element engages in a closure opening in the wall area of the storage box.
  • the closure element has a recess and a blocking element is assigned to the recess.
  • the blocking element can be displaced into at least one position blocking the closure element and one position releasing the closure element. Furthermore, the blocking element engages in the blocking position in the recess of the closure element.
  • a tumbler is generally understood to mean any form of mechanism that is suitable for holding a separating device, such as a door, in a closed position.
  • the preferred area of application for the relevant locking device is safety technology, particularly in the area of machines and systems. Danger areas are secured there by movable guards, e.g. B. pivoting or sliding doors.
  • Safety locking devices are provided on these, in particular to prevent access to hazardous areas on machines and systems until dangerous machine movements have stopped.
  • the tumbler according to the invention comprises an actuating part and a tumbler part, which are provided for attachment to two parts that are separate from one another and can move in relation to one another.
  • the actuator part and guard locking part can be attached, for example, to the moving and to the fixed part of a guard, for example to a moving door part and a fixed frame or stop part.
  • the actuating part is preferably provided for attachment to the moving part of a separating protective device, e.g. protective door, and is particularly preferably designed autonomously for this purpose, i. H. without wired electrical supply.
  • the guard locking part is preferably provided for attachment to the fixed part of a guard and, as will be explained in more detail below, can have a wired supply line for electrical supply, transmission of data on the status of the guard locking and/or for receiving control commands, in particular actuation for release or locking the tumbler.
  • the actuating part of the tumbler has two receptacles located opposite one another, while the tumbler part has two bolt elements which can be displaced along a common axis of movement.
  • the bolt elements In an extended closed position, the bolt elements are accommodated in at least one, preferably both, receptacles.
  • the bolt members In an inner retracted position, the bolt members are outside of the sockets. The bolt elements are thus in the locking position in engagement with the receptacles, as a result of which the tumbler is closed, i.e. the actuating part and tumbler part are fixed against one another.
  • the receptacles are preferably arranged at a distance from one another, with the distance preferably being only slightly greater than the width of a housing part of the tumbler part that accommodates the bolt elements.
  • the recordings can, for example, as cavities, Recesses, openings can be formed and preferably receive a bolt element in such a way that it is locked against movement by the formed engagement in at least one, preferably in all, directions running transversely to the axis of movement.
  • the receptacles can preferably be in the form of troughs.
  • the bolt elements are preferably movably mounted independently of one another along the common axis of movement.
  • they can have a head part, which projects out of a housing of the locking part in the closed position, and an adjoining shaft part, which always remains inside a housing of the locking part.
  • the bolt elements are preferably made of metal.
  • the bolt elements are preferably elongate, i.e. their extension in the direction of the movement axis is greater than in the transverse direction.
  • Various cross-sectional shapes are possible for the bolt elements, for example rectangular or polygonal cross-sections, a round cross-sectional shape being particularly preferred.
  • At least one spring element is provided in order to act on the bolt elements in the direction of the closed position.
  • a separate spring element can also be provided on each of the bolt elements, the spring force of which acts outwards.
  • Stops for the bolt elements are preferably formed on the tumbler part, so that these can only be pushed outwards as far as a stop position and are held in the stop position.
  • At least one locking element is provided according to the invention.
  • the locking element is movable at least between a release position, in which the bolt elements are movable and in particular can be moved from the locking position to the retracted position, and a locking position in which the bolt elements are locked in the closed position, i.e. are preferably blocked by the locking element.
  • a release position in which the bolt elements are movable and in particular can be moved from the locking position to the retracted position
  • a locking position in which the bolt elements are locked in the closed position, i.e. are preferably blocked by the locking element.
  • separate locking elements can be provided for the two bolt elements, or the two bolt elements are locked by a common locking element.
  • the tumbler according to the invention is particularly suitable for a very compact arrangement.
  • Particular advantages result in this connection from the combination of the bolt elements, which are spring-loaded in the direction of the closed position, with a locking element.
  • a force required for moving the bolts can preferably be applied at least predominantly or even completely by the spring element, so that no actuator, motor drive or the like is required to bring about this movement of the bolt elements.
  • the mere locking of the bolt elements that are already in the locking position requires significantly less effort and forces than the movement of the bolt elements, especially if the locking is passive, i.e. a movement by means of an actuator is only used to move the locking element while the locking element is in the locking position is positioned self-locking, so that no action by an actuator is necessary to remain in the locked position.
  • the two-sided locking effect of two bolt elements acting in opposite directions results in a particularly high holding force of the tumbler. Forces that are applied in the closed position between the actuating part and the locking part, for example when trying to open a door, are distributed favorably due to the action of the bolt elements on both sides, with twisting and canting being largely avoided.
  • a controllable drive for the locking element is provided.
  • This can particularly preferably include an electromechanical actuator, such as an electric motor, electromagnet, etc.
  • the locking element can be actively moved between the closed position and the retracted position by means of a control command.
  • the locking element is preferably arranged to be self-locking, so that it remains in the locking position even without an active force being exerted by the actuator.
  • the locking element is designed as a threaded element.
  • the threaded element By rotating the threaded element relative to an engagement element, the threaded element can be moved between the release position and the locking position.
  • the coupling device can, for example, be designed to be self-locking due to the thread, so that the bolt elements forces acting on the locking element do not lead to rotation and thus movement of the locking element.
  • the locking element can be rotated, for example, by a controllable drive.
  • a first and a second threaded element can be provided as locking elements, which are assigned, for example, to the two bolt elements.
  • a drive for rotating the threaded elements can then preferably be arranged between the threaded elements, with both threaded elements preferably being able to be driven simultaneously, preferably synchronously, with one drive.
  • the threaded elements can preferably be arranged and designed in such a way that they can be moved in the direction of the axis of movement by rotation about an axis of rotation that corresponds to the axis of movement of the bolt elements or is at least parallel to it.
  • the threaded element can have an external thread and a matching internal thread can be formed as an engagement element on a housing that surrounds the bolt elements at least in the retracted position.
  • the internal thread can, for example, be provided in one piece with the housing in order to form a particularly strong structure.
  • a threaded element with an external thread allows a relatively large thread surface for the transmission of larger forces while still having a compact design.
  • an engagement can be provided on the bolt elements, for example a notch, bore, etc.
  • the engagement can also be formed by a trough, edge, etc.
  • a locking member may be movably mounted transversely to the axis of movement of the bolt members and may be engaged in the locking position so as to establish the lock.
  • the bolt elements can have aligned engagements in the closed position, so that both bolt elements can be locked in the closed position with a single locking element.
  • the actuating part can be designed as a clamp with two spaced clamp jaws in which the receptacles are formed.
  • a connecting part is preferably provided which extends between the clamping jaws and connects them. Clamping jaws and connecting part can also be designed in one piece in order to create a device suitable for absorbing high forces in a particularly simple manner.
  • At least one of the bolt elements preferably both bolt elements, have a rounding or bevel at the front end arranged in the direction of a receptacle. It is also advantageous if a rounding or bevel is formed on at least one edge area surrounding the receptacles on the actuating part, with roundings or bevels particularly preferably being provided in the edge area of the receptacles both on the inside and on the outside.
  • Such bevels or roundings are preferably arranged in such a way that when the actuating part and the locking part move in the direction transverse to the axis of movement of the bolt elements, interaction between the border of the receptacles and the bolt elements results in the bolt elements being pressed in the direction of the retracted position against the force of the spring element become.
  • a relative positioning of the actuating part and the tumbler part can be achieved in a particularly simple manner, with the bolt elements being accommodated in the receptacles.
  • Bevel angles relative to the movement axis of preferably more than 15°, more preferably 30° or more, are preferred. In the case of a rounding, it can be sufficient if the bevel angles mentioned are achieved at least in sections by the corresponding tangent.
  • a housing is preferably provided on the tumbler part, in which the bolt elements are displaceably arranged, the housing having openings at opposite ends for the bolt elements to exit.
  • the spring element is preferably also provided inside the housing, as well as more preferably a drive for the movement of the locking element.
  • a connection for a cable for electrical power supply and/or control can be provided on the housing.
  • a sensor for the position of at least one of the bolt elements and/or the locking element can be provided on the tumbler, preferably on the tumbler part.
  • the sensor is preferably designed to use an electrical signal to determine the position of the to signal each element, in particular whether the bolt elements are in the closed position.
  • Various devices can be used as sensors, in particular buttons or other contact devices. Contactless sensor devices are preferred, for example based on the optical, capacitive and/or inductive sensor principle.
  • a coil can be provided on the receptacles, the inductance of which changes due to the receptacle of a metal bolt element within the receptacle and leads to a changed sensor value, so that a release signal can be emitted, preferably when bolt elements are received in the receptacles on both sides, to enable the operation of a machine or system, for example.
  • the safety device comprises a separating protective device in order to block access to a machine or system.
  • the locking part and the actuating part are arranged on a movable part and a fixed part of the protective device, any arrangement being possible, but the arrangement of the actuating part on the movable part being preferred.
  • the guard locking is connected directly or indirectly to a controller for the machine or system.
  • a controller for the machine or system.
  • Appropriate design of the controller can ensure that the guard locking can only be opened when the machine or system is in a safe operating mode.

  • the coupling between the motor 40 and the locking elements 50b takes place via drivers 44 of non-round, here for example rectangular cross-section, which are positively locked in matching bores 46 in the locking elements 50a, 50b and are therefore non-rotatable, but axial are relocatably included.
  • the drivers 44 arranged on both sides By rotating the shaft of the motor 40 protruding on both sides, the drivers 44 arranged on both sides also rotate and thus drive the locking elements 50a, 50b in rotation, so that they move in the axial direction, depending on the direction of rotation either outwards or inwards.
  • the bolt element 20a is pressed by the spring 30a up to the stop 34a, so that the head of the bolt element 24a protrudes from the housing 24.
