Definitions

  • the present invention is directed to a lock with a lock housing, in which a locking mechanism is arranged with a locking element.
  • the locking element is pivotable between a first position for closing the lock and a second position for opening the lock, wherein the locking element has a movement range between the first and the second position.
  • locks can be subdivided into locks having linearly movable locking elements, and locks having a locking element pivotable about a pivot axis.
  • Locks with locking elements which are arranged pivotably within the lock housing, can be placed in a closed state in which the locking element protrudes from the lock housing and they can be placed in an open state in which the locking element is retracted into the lock housing.
  • Locking elements which are designed for pivoting movement within the lock housing, have a hook shape in order to engage in a striking plate that forms the opposite side of the lock.
  • Locks of the above-mentioned embodiment are used in doors or windows for buildings, which locks can also be used in the field of furniture such as cabinets, drawers or security containers.
  • the locking element is pivotable between a first and a second position by a key in a lock cylinder, which cooperates with the locking mechanism.
  • a door handle may cooperate with the lock mechanism to move the lock member between the associated positions.
  • the locking element In the closed position, the locking element extends from a cuff, which forms the front of the lock housing. In the open position, the locking element is retracted into the lock housing. Consequently, due to the range of movement of the locking element in both the forend and in the front of the lock housing an opening is necessary. This opening leads to a security problem because the locking mechanism can be manipulated through said opening.
  • the opening forms an entrance to reach the locking mechanism, for example by a manipulation tool. With a manipulation tool, the locking mechanism can be damaged or the mechanism can be activated such that the closed state of the locking element is transferred to the open state.
  • the invention has for its object to overcome the above-mentioned disadvantages.
  • the invention includes the technical teaching that a protective element is arranged within the range of motion to provide a protective shield against manipulation of the locking mechanism, wherein the protective element is designed as a displaceable element with a first end, which is connected to the locking element, and is designed with a second end which extends freely movable into the lock housing.
  • the protective element according to the present invention is not designed as part of the lock housing.
  • the protective element according to the invention provides a protective shield and is movably arranged between the opening in the forend and the front of the lock housing and the locking mechanism, and the locking mechanism can not be manipulated by a manipulation tool through the opening. Due to the arrangement of the protective element, which includes a connection to the locking element, the entire locking mechanism is protected against ingress over the opening. Due to the connection between the protective element and the locking element, which is independent of the pivoting position of the locking element, the locking mechanism is protected against the introduction of a manipulation tool. Due to the movable behavior of the protective element, the protective effect is further increased. Consequently, another security effect is achieved.
  • the second end of the protective element is freely movable at least between an inner limiting element and an outer limiting element.
  • the end of the protective element which forms the opposite side of the connection between the protective element and the locking element, has a freely movable state and extends into the lock housing. Due to the connection of the protective element to the locking element, the protective element performs a movement between different positions when the locking element is pivoted between the first and the second position. Consequently, the lock housing has at least one inner limiting element and an outer limiting element, wherein at least the inner limiting element is arranged between the movement region of the locking element and the closing mechanism or this is formed by an inner housing wall within the lock housing.
  • the inner and outer boundary elements form stop devices, wherein the protective element is movably disposed between these two devices, and wherein the movement relates to the second end of the protective element, which extends freely movable in the lock housing.
  • the limiting elements are formed by cylindrical elements, which may have a threaded bore for fastening parts of the closing mechanism or, for example, a cover element for covering the lock housing.
  • the locking mechanism on a transmission element for interacting with a lock cylinder, wherein the transmission element is rotatably received in the lock housing.
  • the transmission element forms a kind of cylinder with a driver geometry for engagement in the lock cylinder with a rotary member, which forms the opposite side of the driver geometry.
  • the locking mechanism comprises a lever element which is connected to the locking element, wherein the interaction between the transmission element and the lever element has at least two gear elements.
  • the first of the two transmission elements has for interaction with the transmission element on a tooth structure, wherein the first transmission element is rotatably received by a pivot pin in the lock housing.
  • the connection between the two gear elements comprises a driving pin, wherein the rotational movement of the first gear element over a certain Angular range is decoupled from the rotational movement of the second gear element.
  • the lever element forms a transmission element between the locking element and the second transmission element. Therefore, the lever member is received by two pivot pins, wherein the first pivot pin is mounted on the locking element and the second pivot pin is arranged on the second transmission element. Due to the kinematics between the locking element, the lever element and the rotational movement of the second transmission element, a rotational movement of the transmission element leads to a pivoting movement of the locking element.
  • the lock housing comprises a face plate with an opening which is arranged in the movement region of the locking element, in which the locking element is at least partially retracted, when the locking element is pivoted to the second position for opening the lock. Consequently, the protective element is arranged across the opening to protect the locking mechanism with the transmission element, the lever element and the transmission elements against manipulation through the opening in the forend and in the front of the lock housing. Due to the arrangement of the protective element in the movement area above the opening, it is necessary to receive the protective element in a movable manner. Consequently, the connection between the locking element and the protective element comprises a pivot pin which is arranged within the locking element.
  • the first end of the protective element is formed as an eyelet, which extends around the pivot pin to provide a joint between the protective element and the locking element.
  • the protective element is arranged adjacent to the outer limiting element, when the locking element is pivoted to the first position for closing the lock.
  • the protective element may come to rest against the inner cage wall. When the locking element is pivoted to the closed position, the protective element follows this movement.
  • the outer restricting member is disposed adjacent to the forend and the protective member can move toward the opening in the forend.
  • the inner restricting member and the inner cage wall constitute a movement stopper for the protective member in the second position. Consequently, the protective element is arranged adjacent to the rear side of the locking element when the locking element is arranged in the second position, wherein the second end of the protective element has a certain distance from the outer limiting element.
  • the protective element may be designed as a flexible or innflexibles element, wherein by a flexibility of the protective element combined with a high-strength steel material, which is hardened and has a spring behavior, a maximum protective effect can be achieved.
  • the protective element may have a straight contour or a curvature with a convex shape, which is directed towards the closing mechanism.
  • the curve shape can form an alternative due to the arrangement of the protective element within the range of movement of the locking element.
  • the protective element has an oblique arrangement within the lock housing when the locking element is pivoted to the first position, wherein the protection element has a vertical arrangement within the lock housing when the locking element is pivoted to the second position.
