Definitions

  • the invention relates to a device for openable latching of an openable element.
  • Devices of this type are used when it is desirable to keep an open- able element, such as a door, a window, a hatch or similar, in closed position while it simultaneously is possible to open it by means of a control device, for example in the form of a door handle, doorknob, push bar, push plate or similar.
  • a control device for example in the form of a door handle, doorknob, push bar, push plate or similar.
  • devices of this type are used for emergency exit doors, fire doors, smoke separation doors and similar.
  • Such types of doors are commonly arranged with latch function or similar only, so that the door is kept in closed position by means of the latch but can be opened fast and easy when required.
  • the invention also relates to an openable element comprising the device and use thereof.
  • Such a type of device is a conventional locking device having a latch function.
  • a prior art locking device comprises a lock housing having a latch, such as a spring bolt or similar, being movable between a protruded position and a retracted position, and a pivotable arm cooperating with the latch and connecting the latch with a control device, such as a door handle or similar, for operating the latch.
  • the latch is arranged with a strike surface for cooperation with an element of a door frame, such as a striking plate or similar, so that the latch is displaced automatically towards its retracted position when cooperating with the element of the door frame so that the door can be closed without the latch being brought to its retracted position by means of the control device.
  • the latch is spring-loaded towards the protruding position.
  • a disadvantage of such devices for openable latching of an openable element according to prior art is that they are unreliable due to their structure.
  • a problem with such devices according to prior art is that they are susceptible to wear and outer stress. For example, there is a considerable risk that parts of the device break due to vibrations or that a spring in the lock housing breaks, which can result in a jammed device and that a door associ- ated with the device cannot be opened. Hence, there is a considerable risk that wear and outer stress make the device unusable.
  • An object of the present invention is to avoid the disadvantages presented above and problems of the prior art and provide a safe and durable device for openable latching of an openable element, such as a door.
  • the device according to the invention results, for example, in that doors for emergency exits and similar can be latched in a safe way while it simultaneously is ensured that such door can be opened when needed.
  • the present invention comprises a device for openable latching of an openable element, comprising a latch housing having a latch being adjustable between a protruding position and a retracted position, and a movably arranged arm cooperating with the latch, wherein the arm is anranged for connection with a control device for controlling the latch through the arm, characterised in that the arm is arranged with a blocking surface for engaging a portion of the latch in the protruding position of the latch and thereby forming a blocking function for preventing the latch from being displaced into the latch housing due to a force acting upon an outer side of the latch outside the latch housing, and that the device comprises a movably arranged unblocking element having a strike surface for cooperation with an element outside the latch housing, and a portion for cooperation with the ami, wherein the unblocking element is anranged for unblocking the blocking function when a force is applied on the strike surface of the unblocking element.
  • the device functions as a safe and reliable latch function having only a small number of movable parts and wherein the latch is kept in its protruded position in a reliable way also in environments of great outer stress.
  • the latch resists shocks and other forces in environments such as traffic tunnels and similar.
  • the device can be arranged without a return spring and other parts that can jam a door.
  • the latch can be a so called spring bolt, which resists outer pressure on the latch by means of the unblocking element.
  • the latch and the unblocking element can function as a spring bolt which fall back into the latch housing when struck by an ele- ment outside the latch housing, such as a wall edge, frame or similar.
  • the latch can be connected to the latch housing through a first pivot and the unblocking element can be connected to the latch through a second pivot, wherein the latch is pivotable between its protruded and retracted position and wherein the unblocking element is pivotable towards the arm to un- block the blocking function.
  • the unblocking element can displace the arm in relation to the latch to free the latch from the blocking function, so that the latch can be turned around the first pivot towards its retracted position.
  • the unblocking element can be arranged with a first leg and a second leg arranged in an angle to the first leg, wherein one end of the first leg is con- nected to the latch through the second pivot and wherein a free end of the second leg forms the portion for cooperation with the arm.
  • the unblocking element can be L-shaped.
  • the latch can be arranged with a recess for receiving the unblocking element, so that the unblocking element is dis- placeable by rotation into the recess due to force acting upon the strike sur- face of the unblocking element.
  • the recess can be L-shaped corresponding to the unblocking element, so that the unblocking element can be rotated into the recess.
  • the latch can be arranged with a space for receiving a second portion of the arm when adjusted from the protruding position to the retracted posi- tion.
  • the space can comprise a first side and a second side opposite the first side, so that the arm cooperates with the first side when the device is adjusted to unlatched position in which the latch is in its retracted position by cooperation with an element outside the latch housing, such as a frame, and so that the arm cooperates with the second side when the device is adjusted to unlatched position by means of the control device.
  • the first side of the space of the latch pushes the arm during adjustment to unlatched position by means of a spring bolt function due to an outer force from an element outside the latch housing, such as a frame, wherein the arm pushes on the second side of the space of the latch during adjustment to unlatched position by operating the control device.
  • the device can be entirely mechanical. Hence, a simple and safe device is provided which can be made reliable and durable also in environ- ments wherein outer stress in the form of high humidity, considerable pressure differences or substantial changes in temperature is common.
  • the control device and a connection between the control device and the device can be mechanical.
  • the control device, the connection and/or the device comprise one or more electrically controlled components.
  • the components of the device i.e. the latch housing, the arm, the latch and the unblocking element, can be arranged in metal, such as stainless steel, and can be massive. Alternatively, the components are arranged in a durable composite or plastic material.
  • the invention also relates to an openable element comprising at least one device according to the invention.
  • the openable element can be a door, such as an emergency exit door, fire door, smoke separation door or similar.
  • the invention also relates to the use of one or more devices according to the invention to provide a safe latch function of such an openable element.
