Definitions

  • the invention relates to a rod lock for locking a door leaf on a door frame with at least one locking device designed as a turnbuckle lock and a rod, which are coupled to one another via at least one rod coupling.
  • Rod locks are used in many areas of technology to lock doors in their closed position, ie to lock the movable door leaf to the fixed door frame in a form-fitting manner.
  • door should be understood to mean all types of openings that can be closed via a movable closing element, for example gates, hatches, flaps, etc.
  • the bar locks In order to lock the movable door leaf to the door frame surrounding the door opening, which can be formed by the edge of the opening itself or by a separate part, the bar locks have at least one but usually several locks.
  • the rod locks mostly have an actuation in the manner of a turning or pivoting handle, which is coupled via a rod coupling to the rod of the rod lock in such a way that its rotary movement is converted into an axial movement of the rod.
  • the rod is coupled to at least one lock via a further rod coupling in such a way that the axial movements of the rod are used to actuate the lock and thus to pivot its locking element.
  • locks are used with a locking element which is pivotable about a locking axis and which can be pivoted between an open and a closed position, mostly by about 90°.
  • rod locks are known, in which the locks are designed as rotary clamp locks.
  • the locking element is not only pivoted between its open and closed position, but also moved in the axial direction to generate a clamping movement.
  • the two movements are usually separate from one another, it often being the case that the locking element is initially pivoted in a first movement section.
  • the locking element is transferred from its open position to its closed position and the door leaf is secured against opening.
  • the locking element is then moved axially and the door leaf is clamped in the axial direction against a door seal provided between the door leaf and the door frame.
  • Both the first and the second movement section are often 90°.
  • a bar lock the locks are designed as such rotary clamping closures, for example, from DE 20 2013 104 879 U1 known.
  • a rod coupling is provided on each locking device in this rod fastener, which is designed in the manner of a lock case having a gear with a drive pinion.
  • Neighboring lock cases can each be connected to each other via comparatively short rods. With a corresponding number of lock cases and associated rods, a rod lock can also be constructed in this way with a larger number of locks designed as rotary clamp locks.
  • the rod coupling as a pivoting lever
  • a structurally simple design of the rod lock can be achieved even with a large number of locks designed as rotary clamp locks.
  • the design of the rod couplings as pivoting levers results in a type of linkage coupling of several locks via a common rod with a structure that is as simple as it is reliable.
  • an advantageous embodiment provides that one end of the lever of the rod coupling is connected to the rod via a joint and the opposite end of the lever is non-rotatably connected to the locking mechanism. Due to the articulated connection of one end of the rod coupling to the rod, it can be pivoted by moving the rod axially. Due to the non-rotatable connection of the other end of the lever to the lock, the pivoting movement of the rod coupling can be transferred to the lock and this can be actuated.
  • the joint has a joint pin arranged rotatably within a joint eye.
  • the hinge eye can be designed as a through hole.
  • the joint eye can be arranged on the rod, resulting in a simple construction of the rod. This can be particularly useful in situations where the locking bar needs to be adapted to different doors. In such situations, the rods must be exchanged according to the respective installation situation and replaced with rods of the appropriate length.
  • the rods can be manufactured in a simple manner by bringing them to the appropriate length and providing them with the appropriate bores.
  • joint eye is designed as a slot that accommodates the joint bolt in a displaceable manner.
  • a particularly advantageous embodiment also provides that an actuation for actuating the locking mechanism is coupled to the rod via a rod coupling.
  • a structurally advantageous embodiment provides that the rod coupling is also designed as a pivoting lever. In this way, both the rod coupling via which the rod is coupled to the locks and the rod coupling via which the rod is coupled to the actuator can be designed as a common linkage coupling. This results in a structurally particularly simple and reliable structure.
  • the rod coupling associated with the at least one locking mechanism and/or the rod coupling associated with the actuation form a parallelogram linkage together with the rod.
  • the locking device has a locking element which is designed to be rotatable about a locking axis and movable along the locking axis.
  • the turn-clamp functionality of the lock can be generated via the locking element.
  • the rotary movement and the axial movement of the locking element are superimposed at least in sections.
  • the locking mechanism can be actuated with a small operating angle in comparison to a rotary clamping closure, in which these movements take place in movement sections that are separate from one another.
  • a further advantageous embodiment provides that the locking angle of the locking element corresponds to the pivoting angle of the rod coupling. If, for example, the locking element is pivoted by 90° between its open and its locking position, the required clamping movement can also be achieved immediately by a pivoting angle of the rod coupling also by 90°.
  • the swivel angle is less than 180°, preferably less than 135° and even more preferably equal to 90°. In this way, the locking can be established or released in a simple manner via the parallelogram linkage. Over-dead center positions, such as could arise with a pivoting angle of the rod coupling of 180° and more, are avoided.
  • a further advantageous embodiment provides that the locking element is designed as a locking tongue or as a rolled tongue.
  • a locking tongue is characterized by its structurally simple, cost-effective design.
  • a roller tongue offers the advantage that it can be used to increase the clamping movement of the lock in a simple manner.
  • a conical roller can be provided for this purpose.
  • the lock be a locking shaft which is rotatably and axially movably arranged in a locking housing having.
  • the locking element can be firmly connected to the locking shaft at one end of the latter.
  • the lock has a guideway for converting the rotary movements of the locking shaft into an axial movement of the locking shaft.
  • a pivoting movement applied to the locking mechanism can be converted into both a rotary and a tensioning movement of the locking element via the rod coupling designed as a pivoting lever.
  • the guide track has sections with different gradients. In this way, the proportion of the resulting axial and/or tensioning movement of the locking element can be adjusted.
  • the axial movement can initially be kept small in a first movement section and then, as soon as the locking element has reached behind the door frame, the axial movement can account for a larger proportion, so that only then does the tensioning movement predominate.
  • a further embodiment provides that two guide tracks are provided on opposite sides of the locking shaft. A symmetrical arrangement can be achieved in this way. Canting or the like of the shaft within the housing is not to be feared.
  • the bar lock can have an emergency release.
  • the emergency release be designed in such a way that the rod can be decoupled from the actuation via the emergency release and the locking device can be actuated to unlock the door leaf.
  • the emergency release has a dual function. Firstly, the rod with all the locks coupled to the rod is decoupled from the actuation via the emergency release, with the coupling between the rod and the locks being retained. In addition, the emergency release is also used to operate all locks and thus to unlock the door leaf. In this way, an easy-to-operate emergency release can be provided independently of the number of locks provided on a rod.
  • the emergency release has a decoupling device for decoupling the rod from the actuation.
  • the rod can be mechanically decoupled from the rod in a simple manner via the decoupling device. After the decoupling has taken place, the rod can be moved and the lock coupled to this can be actuated without this having any effect on the actuation.
  • the decoupling device has a decoupling element which can be transferred from a coupling position into a decoupling position transversely to the direction of the rod.
  • Structurally simple decoupling devices can be designed in which only a short transfer path of the decoupling element between the coupling position and the decoupling position is provided.
  • the decoupling element is pretensioned in the direction of its decoupling position and is secured by a securing element. In this way, decoupling can take place automatically by removing the securing element.
  • the decoupling element in the other Direction that is biased in the direction of the coupling position. In this case it would be conceivable, for example, to carry out the decoupling manually, for example by means of a decoupling handle, knob or the like.
  • a structurally advantageous embodiment also provides that the decoupling element is designed as a spring bolt.
  • a further advantageous embodiment provides that the securing element for decoupling the coupling element can be moved along a decoupling path in the direction of the rod.
  • the decoupling element which is pretensioned in a direction transverse to the rod, can be released so that it can move automatically into its decoupling position. The result is a simple decoupling of the rod from the actuation.
  • a further advantageous embodiment provides that the emergency release has an emergency actuation, via which the at least one lock can be actuated.
  • the rod which is still coupled to the locks, can be moved via the emergency actuation and the lock can be actuated in this way.
  • a further advantageous embodiment provides that the emergency actuation has a driving device, via which the emergency actuation is coupled to the rod and can be moved relative to the rod along a free-running path.
  • the emergency control can be moved freely in relation to the rod along the free-wheel path. In this range, a movement of the emergency handle does not result in a transmission of the movement to the rod. Only at the end of the freewheeling path is the emergency actuation coupled to the rod and taking it with it via the corresponding driver device.
  • the movements of the emergency control relative to the rod are guided via an axial guide. This results in a defined movement of the emergency control relative to the rod along the freewheel path.
  • the emergency actuation has a handle, via which the emergency actuation can be actuated by hand.
  • the handle can also be signal colored to the operator and have an indication of how to move the handle. This can be of particular advantage in emergency situations with only poor visibility, since the operator recognizes the handle designed in a signal color as such over longer distances and receives information as to how the emergency actuation is to be actuated.
  • an advantageous embodiment further provides that the free-running path is limited by at least one stop that can be moved relative to the rod and at least one stop that is fixed to the rod. As soon as the two stops come into contact with one another, the stop that is fixed to the rod is carried along by the stop that can be moved relative to the rod, and the rod is moved for the purpose of emergency unlocking.
  • a constructively advantageous embodiment provides that the driver has an elongated hole, the ends of which form two movable stops which interact with a stop fixed to the rod.
  • the rod can not only be unlocked in an emergency, but can also be moved in the opposite direction to the direction of emergency unlocking.
  • a further embodiment provides that the rod-fixed stop extends at least partially into the elongated hole, resulting in a guided movement in the area of the driver.
  • a particularly user-friendly configuration is characterized in that the emergency release is designed as a one-handed operation. Regardless of the number of locks present, the emergency release can be gripped and operated with one hand. The operator can use the second hand for other purposes, such as holding a flashlight or a tool.
  • a further embodiment provides that the decoupling device and the emergency actuation interact in such a way that when the emergency release is actuated, first the decoupling device for decoupling the rod from the actuation and then the emergency actuation for actuating the lock is activated. In this way, both decoupling and actuation can be achieved in a single sequence of movements.
  • the locks of the bar lock can be designed as rotary clamp locks.
  • pivoting a locking element of the locking mechanism not only a form-fitting locking can be achieved via the twist-lock fasteners, but also compression by moving the locking element axially a door seal provided between the door leaf and the door frame. In the case of air conditioning systems, climatic chambers or similar applications, this can result in a pressure-tight closing of the door.
  • the rod lock is provided with two rods that can be moved in different directions, it can have a corner deflection.
  • the movements of one bar can be converted into a movement of the other bar via the corner drive.
  • the corner deflection has a flexibly designed deflection element, which is movably mounted in a guide and can be connected to the rods via assembly elements.
  • the assembly elements each have at least two optionally usable assembly points for connection to the rods.
  • One or the other mounting points can be used according to the type of movement of the respective rod. The result is a flexible system that can be used with different bar locks.
  • an advantageous embodiment provides that at least one of the assembly points is designed in such a way that the rod retains a rotational degree of freedom. With such a mounting point, the rod can be articulated so that the rod can be pivoted following the movements of the mounting element.
  • the assembly point is designed as a jointed eye.
  • a bolt can engage in the assembly point to form an articulated connection.
  • a further advantageous embodiment provides that at least one of the mounting points is designed in such a way that a translational degree of freedom of the rod is retained.

In addition, a rotational degree of freedom can also be retained.
  • an embodiment is advantageous in which the mounting point is designed as a slot.
  • a bolt can be accommodated in a translationally movable manner within the elongated hole. Depending on the shape of the bolt, it can also be moved in rotation.
