Definitions

  • the present invention relates to a bar lock with a lock housing, in which a lock cylinder is arranged with a rotating locking lug, and with at least two locking bars which are extendable by actuation of the lock cylinder in opposite directions from the lock housing.
  • Bar locks are used to secure windows or doors against burglary, especially for the subsequent increase in protection against burglary.
  • the doors of old buildings are often retrofitted with a bar lock.
  • the lock housing is attached to the wing of a door or window, the two locking bars engage in extension into corresponding lock cases of the door or window frame or in a recess in the floor and secure the wing against unauthorized opening.
  • the two locking bars can be driven by the respective drive elements mounted separately in the lock housing for the extension movement.
  • the respective drive element can be mounted translationally displaceable in the lock housing, wherein the drive elements are movable independently of each other.
  • each locking bar can be coupled via its own drive element with the rotating locking lug, resulting in a reliable operation of the rod lock. Furthermore, a large angular range of the rotational movement of the locking lug is used for driving the locking bars.
  • a bar lock also flexible design options, since, for example, a plurality of locking bars can be attached to a single drive element, as will be explained below.
  • such a rod lock also allows extended use, since a simple conversion between a configuration for left-hinged doors and a configuration for right hinged doors is feasible, as will also be explained.
  • the drive elements are arranged such that the closing lug of the lock cylinder acts during a closing rotational movement, first only one of the drive elements and then only the other drive element.
  • This embodiment makes use of the knowledge that a synchronous counter-rotating movement of the two locking bars is not necessary for the locking function of the bar lock. For security against burglary, it is only important that both locking bars are extended after the closing process as the final result. Therefore, the locking bars can also be driven sequentially in time, which can be advantageous in terms of the maximum applied by the closing force (corresponding to the maximum torque to be applied).
  • the closing lug of the lock cylinder during the closing rotational movement of one of the drive elements in the course of a first half turn and act on the other drive element in the course of a subsequent to the first half turn second half turn.
  • two drive elements can be driven sequentially by a turn (Tour) of the locking lug.
  • the drive elements may in particular be arranged on opposite sides of the lock cylinder relative to a rotation axis of the closing nose. It can thus be easily ensured that upon rotation of the locking lug of one of the drive elements is moved upward and the other drive element down.
  • the drive elements can each be displaceably mounted in the lock housing in and against an extension direction of the respective locking bar. There is thus no costly deflection required to implement the movement of the drive elements in the desired movement of the locking bars. This allows the avoidance of lossy power transmission chains.
  • the drive elements may in particular each comprise a transverse (preferably perpendicular) extending to an extension direction of the respective locking bar stop portion on which acts the locking lug.
  • the respective stopper portion may in particular be formed by a projection, e.g. through a stop tongue.
  • the locking lug presses in this embodiment, the relevant drive element directly in the extension direction, so that there is a particularly simple construction.
  • a further embodiment of the invention provides that the drive elements can also be stored in the lock housing in a position rotated by 180 degrees relative to a base state.
  • the respective drive element can optionally be reversed about such an axis inserted into the lock housing, which corresponds to the aforementioned extension direction of the associated locking bar (ie the direction of movement of the drive element).
  • a rod lock for a right hinged door can be easily converted into a bar lock for a left-hinged door, and vice versa.
  • the drive elements are common parts, i. are identical. This results in low production costs.
  • the drive elements are designed as flat strike plates, wherein the locking lug acts on respective stop edges of the strike plates.
  • the stop edges here correspond to the aforementioned stop sections.
  • Such strike plates are particularly simple and inexpensive to produce, for example as a stamped and bent part.
  • the stop edges may each be formed on a drive recess of the associated strike plate.
  • each strike plate Preferably, two drive recesses arranged successively with respect to an extension direction of the locking bar are provided on each strike plate.
  • the closing lug of the lock cylinder can thus engage successively in successive turns in the two drive recesses of the respective strike plate and move the respective strike plate in each case by an offset unit. In this way, a two-speed closing of the rod lock can be done.
  • the striking plates are L-shaped.
  • one leg of an L-shaped striking plate extend in the extension direction, while the other leg extends transversely to the extension direction.
  • the transverse leg here offers an extended attack or attachment surface for the associated locking bar.
  • the drive elements may each have a plurality of locking bar attachment openings.
  • the attachment openings e.g. several locking bars are attached to a drive element.
  • This allows the driving of a plurality of locking bars by means of a single drive element, whereby the safety of a bar lock can be further increased.
  • two locking bars extending obliquely across the wing may be provided.
  • the attachment openings may in particular be provided on a leg extending transversely to the extension direction of the locking bars of an L-shaped strike plate.
  • the two in opposite directions extendable from the lock housing latch bars are each directly attached to the associated drive element. This allows a particularly simple construction, with elaborate power transmission elements are avoided.
  • the drive elements can be selectively locked by means of respective movable tumblers, wherein the tumblers are movably mounted in the lock housing between a release position and a locking position such that the closing lug urges the tumbler in the release position during a closing rotational movement before or upon actuation of a drive element.
  • the tumblers can be formed for example by suitably shaped sheets.
  • One aspect of the invention provides that the tumblers are each movably mounted transversely to an extension direction of the respective locking bar in the lock housing.
  • the blocking effect of the tumblers on the locking bars is particularly high.
  • the tumblers may be biased by respective spring means in the blocking position. This ensures that the tumblers always remain in the locked position except when acted upon by the locking lug. This increases in particular the safety of the bar lock.
  • the two tumblers are biased relative to each other in opposite directions. This increases the security against manipulation.
  • a projection of the associated tumbler engages in a locking recess of the respective drive element for locking the drive elements.
  • an energy store is provided, which at one end with one of the drive elements and connected at the other end to the other drive element.
  • an opposite (ie by 180 ° opposite) coupling between two locking bars can be effected thereby. If one of the latch bars moves down, potential energy can be stored in the energy accumulator and is thus available for subsequent lifting of that latch bar or other latch bar. For example, when locking the bar lock, the upper latch bar must be raised against gravity, and the lower latch bar must be raised when unlocking the bar lock. However, when the bar lock is unlocked, the upper latch bar is moved down by gravity, and the lower latch bar is moved downwardly upon latching of the bar lock.
  • the energy released during these downward movements may be stored in the energy accumulator to assist subsequent lifting of the respective latch bar or other latch bar. Since the locking bars, as explained above, are driven one after the other in time, a single energy store, which is mounted floating between the two drive elements, is sufficient. Thus, with a simple structure, the operation of the rod lock can be further simplified.
  • the named force accumulator can in particular have a length-elastic connecting element.
  • the connecting element between the drive elements is preferably elongate and flexible.
  • it may comprise a rubber band or a spiral spring.
  • the locking bars are thus decoupled from each other in spite of the possibility of mutual power transmission with respect to their extension movements sufficiently, so that they can be driven sequentially in time.
  • the length-elastic connecting element is guided over a stationary deflection section of the lock housing.
  • a force deflection in the desired direction is possible, and it can be provided a long power storage (long travel).
  • Fig. 1 shows in simplified form a door 11 with a frame 13 and a relative to the frame 13 movable wing 15.
  • a bar lock 17 is attached to one side of the door 11 to secure it against unauthorized opening.
  • the bar lock 17 comprises a lock housing 19 attached to the wing 15, and an upper main bar 21a and a lower main bar 21b extending vertically upward and downward from the lock housing 19, respectively.
  • an upper sub bolt rod 23a and a lower sub bolt rod 23b are provided, which extend from the lock housing 19 obliquely upwards and obliquely downward and in Fig. 1 and are shown shortened.
  • a lock box 25 is attached to the frame 13 in which an end portion of the upper main bar 21a is receivable. Furthermore, a recess 27 is provided in the bottom below the wing 15, in which an end portion of the lower main locking bar 21b is receivable.
  • a lock cylinder 29 arranged in the lock housing 19
  • the main locking bars 21 a, 21 b can be extended in opposite directions out of the lock housing 19, so that they come into positive engagement with the lock box 25 and the recess 27 and thereby fix the wing 15 to the frame 13
  • the secondary locking bars 23a, 23b are extended in an opposite manner from the lock housing 19, so that they correspond with corresponding, in Fig. 1 not shown counter elements on the frame 13 in a positive engagement reach.
  • a retraction of the main tie rods 21a, 21b and the secondary locking bars 23a, 23b in the lock housing 19 is also possible by an actuation of the lock cylinder 29.
  • the lock housing 19 comprises a support part 31 and a half-shell-like cover 33 in the form of a U-profile.
  • the cover 33 is held by an inner rosette 35 on the support member 31.
  • the support member 31 is clamped by means of fastening screws 39 with an outer counter-rosette 37.
  • the rod lock 17 underlying the closing mechanism will be described below with reference to the Fig. 4 to 7 explained.
  • the lock housing 19 is shown with the cover removed. From the lock cylinder 29 ( Fig. 3 ) only the pivotable about a rotation axis D locking lug 41 is shown. Furthermore, for better visibility of the remaining components in Fig. 4 the secondary bar bars and in Fig. 5 omitted both the main locking bars and the secondary locking bars.
  • the drive elements comprise an upper flat striking plate 43a and a lower planar striking plate 43b, which are mounted by means of respective clip portions 45 in and against an extension direction A of the main locking bars 21a, 21b slidably mounted on the support member 31.
  • the lower strike plate 43b is shown alone.
  • the striking plates 43a, 43b are each L-shaped and have a longitudinal leg 47 extending along the extension direction A and a transverse leg 49 extending at right angles thereto. As in Fig.
  • the longitudinal legs 47 are in respect to arranged the rotational axis D of the locking lug 41 opposite sides of the lock cylinder, not shown.
  • the transverse legs 49 each extend substantially over the entire end face 50 of the lock housing 19 and each have five attachment openings 51.
  • one of the main locking bars 21a, 21b and one of the auxiliary locking bars 23a, 23b (FIG. Fig. 1 ) directly attached, for example by means of a rod end passing through and screwed into one of the mounting holes 51 screw 53. Due to the large number of existing mounting holes 51 is in terms of number and arrangement of a strike plate 43 a, 43 b associated locking bars 21 a, 21 b, 23 a, 23b high flexibility.
  • the closing plates 43a, 43b each have two drive recesses 55 on a side of the longitudinal leg 47 facing the closing nose 41, which are arranged one behind the other with respect to the extension direction A of the associated main locking bar 21a, 21b.
  • On the opposite side of each longitudinal leg 47 three Arretiencies strictly undertaken 57 are formed, which are also with respect to the extension direction A of the associated main locking bar 21a, 21b successively, but arranged offset to the drive recesses 55.
  • two tumblers 60a, 60b mounted so as to be displaceable perpendicularly to the extension direction A are provided in the lock housing 19, which are likewise designed as flat sheet metal parts ( Fig. 7 ).
  • a bent tongue 61 forms a locking projection, which can engage in one of the locking recesses 57 of the striking plates 43a, 43b, about the respective striking plate 43a, 43b on a sliding movement in or against the extension direction A. prevent.
  • the tumblers 60a, 60b are in such engagement with one of the ArretierausEnglishept 57 of the strike plates 43a, 43b.
  • a curved deflection portion 65 can be seen, which is integrally formed on the support part 31 and thus fixed in the lock housing 19.
  • a length-elastic connecting element 67 is guided, for example in the form of a spiral spring, which connects the longitudinal limbs 47 of the striking plates 43a, 43b to one another (for better clarity only in FIG Fig. 5 shown).
  • the connecting element 67 is fastened by means of fastening screws 68 to the respective striking plate 43a, 43b.
  • the connecting element 67 serves as a force accumulator, which is effective between the two striking plates 43a, 43b.
  • the locking lug 41 Upon actuation of the lock cylinder 29, the locking lug 41 rotates starting from the in Fig. 5 shown position about the rotation axis D counterclockwise and strikes in the course of the first half turn, first on an inclined surface 69 of the right-hand tumbler 60b in the picture. The tumbler 60b is thereby shifted to the right, so that the tongue 61 extends out of the locking recess 57 and releases the striking plate 43b for a sliding movement. Immediately thereafter meets the locking lug 41 on a stopper portion of the lower striker plate 43b in the form of a stop edge formed by the upper drive recess 55. As a result, the locking lug 41 urges the lower striker 43b upwards.
  • the main locking bars 21a, 21b and the secondary locking bars 23a, 23b have each been retracted in opposite directions into the lock housing 19 in two steps, so that the bar lock is retracted 17 is in an open position.

  • bar lock 17 is for a left hinged door 11 as in Fig. 1 shown executed.
  • Reconfiguring for a right-hinged door is possible in a simple manner in that the striking plates 43a, 43b are rotated by 180 degrees with respect to a vertical axis (corresponding to the extension direction A) and replaced with respect to their bearings. A rotation of the locking lug 41 in the clockwise direction then causes an opening of the rod lock 17th
  • the rod lock 17 shown has an advantageously simple structure, since as essential elements in addition to the lock cylinder 29 only the lock housing 19 with support means 31 (eg zinc diecast) and the strike plates 43a, 43b and the tumblers 60a, 60b are required (eg stamped and bent parts). On the other hand, complex transmission components are not required.
  • Both the main locking bars 21a, 21b and the sub-locking bars 23a, 23b are hollow and can therefore be easily cut to the desired extent during assembly.
  • sawing pins 75 are as in FIG Fig. 8 shown inserted into the ends of the main locking bars 21a, 21b and the sub bolt bars 23a, 23b.
  • the saw protection bolts 75 are made of hardened steel and fill the inside of the relevant rod - in Fig. 8 the upper sub bolt rod 23a - completely off.
