Definitions

  • the present invention relates to a lock construction of the kind defined in the preamble of the accompanying Claim 1.
  • the invention also relates to the use of a Scandinavian oval standard cylinder as an axially displaceable lock bolt in a corresponding channel in a lock housing.
  • the invention can be used advantageously in so-called window locks, for instance.
  • window locks One problem encountered when fitting window locks to the windows of an apartment or a house is that it has not earlier been possible to base the window lock on the same lock system as that used with the outer doors of the apartment/house.
  • the window locks used have been in the form of a circular-cylindrical, axially displaceable lock bolt or plunger that can be latched in a locking position of displacement.
  • one and the same key can be used for all window locks in a dwelling, it is still necessary to use mutually separate keys for the outer doors and window locks of the dwelling.
  • An object of the present invention is to provide a lock construction in which a standard cylinder that is intended for doors can be used as an axially displaceable lock bolt. This will enable one and the same key to be used both for the inventive lock construction and the door lock or locks of a dwelling.
  • the object is also achieved with the use of a standard cylinder intended for door locks as an axially displaceable lock bolt in a channel in a lock housing, for instance a window lock or the like, in accordance with the accompanying use Claim.
  • the invention is based on the knowledge that a Scandinavian oval standard cylinder has on its inner end an exposed cylinder back-piece that includes a dogging means which can be rotated relative to the body of the standard cylinder with the aid of a standard cylinder key, and that the standard cylinder body has on its inner end two separated axial bores that enable the standard cylinder to be affixed axially in a door lock.
  • This enables a locking pin for connection to the standard cylinder of the window lock to be fitted in one bore in the cylinder body, whereas a journal shaft of a latching device can be placed in the other bore, wherein the journal shaft may be conveniently spring-biased towards a latching position.
  • a biasing spring can be fitted around the locking pin so as to displace the standard cylinder towards an end position in which the window lock is open.
  • the latching device shall be constructed to be dogged by the dogging means to an opening movement in which the latching element is withdrawn from its engagement with a locking recess.
  • Figs. 1 and 2 illustrate two different possibilities of fitting an inventive window lock.
  • Figs. 3, 4 and 5 are respectively a front view, side view and horizontal view of the lock housing of the window lock.
  • Figs. 6 and 7 are sectioned views which illustrate the lock housing, lock cylinder and associated lock parts from opposite directions.
  • Fig. 8 illustrates schematically the inner end of the standard cylinder used as a lock bolt.
  • Fig. 9 illustrates schematically another inventive lock construction in which the blocking device is a boom whose controlled movement transversely to the direction of bolt displacement is blocked by the standard cylinder or by an element carried thereby.
  • Fig. 10 illustrates schematically an alternative embodiment of the latching device.
  • Fig. 11 is a schematic sectional view taken on the lines XI-XI in Fig. 10.
  • a lock housing 1 having a passageway 2 whose cross-sectional shape corresponds to the outer cross-sectional shape of a Scandinavian oval standard cylinder 3 designated ASSA 701.
  • the key is indicated at 4 and the rotatable back-piece of the cylinder carries a dog 5.
  • the inner end surface 32 of the cylinder body 31 includes two bores 11, 12, which in the normal use of the standard cylinder 3 in a door lock function, are to receive locking screws which secure the standard cylinder 3 axially in the door/lock.
  • an externally threaded locking pin 14 is screwed into the threaded bore 12 and mounted on a tubular distance spacer holder 13 by means of a screw 16 in the bore 11.
  • the spacer holder 13 carries a latching plate 20 which is biased by a spring 21 to a position in which a part of the latching plate lies outside the cross-sectional profile of the cylinder 3 and is able to engage a recess in the lock housing wall when the cylinder 3 is moved down to a lower position in the housing 1.
  • the latching plate 20 is journalled on the journal shaft 13 by means of the screw 16, and that the shape of the latching plate 20 enables the cylinder dog 5 to be swung-in to a position of rotation in which the whole of the latching plate 20 lies inwardly of the cross-sectional contour of the lock housing passageway 2.
  • the latching plate 20 has a part 22 which engages with a recess in the wall of the lock housing passageway when the cylinder 3 is in its downwardly driven end-position, wherewith the locking pin 14 engages a striker plate that can be moved through a side-opening in the housing 1, said opening opening out into the bottom region of the housing 1.
  • the housing 1 has an end-wall 6 which delimits the passageway 2.
  • a bottom bridging member 27 rests on a shoulder in the lower part of the passageway 2 and has an opening for receiving the pin 14 and optionally also an opening for accommodating the head of the screw 16.
  • a coil spring 29 may surround the pin 14 and be fastened thereto such as to bias the cylinder 3 away from said locking position.
  • latching plate 20 is able to slide along the wall of the passageway 2 as the cylinder 3 is moved from its locking position.
  • an inventive window lock can be open and easily locked against the striker plate simply by driving the cylinder down in the passageway 2 until the latching plate snaps-out and engages its recess.
  • the housing 1 can be fitted either to a window frame 30 or to a window casement 31, while the locking plate 7 can be fitted to a window casement 31 or to the window frame 30 by virtue of the construction of the housing shown in Figs. 3-5.
  • the front side of the housing includes through-penetrating openings 35 through which mounting screws are able to pass completely.
  • the opposite rear wall of the housing 1 includes countersunk openings 36 through which the mounting screws can be mounted in the underlying surface, wherein the screw heads are received in the countersunk portions of the openings.
  • the bottom wall 6 of the housing also includes countersunk openings 35 which receive mountings screws in the alternative shown in Fig. 1. It will be evident from Fig.
  • the passageway 2 of the housing 1 has a shape and size which correspond to the cross-sectional shape of the cylinder 3. It will also be evident from Figs. 3 and 5 that the bottom region of the passageway 2 includes ledges or like surfaces onto which the bottom bridging member 27 can be placed.
  • the front wall of the housing also includes a slot-like opening 9 for receiving the tongue of the lock striking plate 7, which typically includes an opening for receiving the locking pin 14.
  • the latching device 13, 16, 20 and the pin 14 may be carried by a base plate which, in turn, is fitted on the inner end of the standard cylinder by means of at least one screw which engages in a corresponding bore 11.
  • Scandinavian oval standard cylinder is meant a cylinder of defacto-standard that is based on the ASSA cylinder No. 701 and/or for instance the cylinder designated Kaba 2048, which, as with all cylinders of this standard, have identical outer dimensions and dogging and bore locations, etc.
  • one part 20 (the latching plate) of the latching device 20, 26 that is manoeuvred by the dogging means is carried by the cylinder 3, whereas the other part 26 of the locking device (the recess) is provided in the housing.
  • the latching plate 20 can be mounted in the housing and the cylinder 3 provided with an element that includes a recess 26 capable of receiving the latching plate 20 in its locking position, wherein the dogging means is able to actuate the latching plate 20 to a position in which it is free from the recess 26.
  • the latching plate 20 is pivotally mounted and is spring-biased towards a latching position in which it engages in the recess 26.
  • the embodiment also includes a ledge or like abutment 74 which defines the rest position of the latching plate 20.
  • the recess 26 is provided in a pin whose free end is rounded so as to swing the plate 20 away from its rest position against the action of the spring as the piston 3 is moved towards its locking position, wherein the latching plate 20 is driven into the recess 26.
  • the lock construction illustrated in Figs. 1-5 includes a blocking device in the form of a striker plate which is adapted for movement in a direction perpendicular to the movement direction of the cylinder 3.
  • the striker plate may be connected to the window casement when the lock housing is fitted to the window frame.
  • the blocking device is generally a boom or bolt whose axial movement is limited by virtue of movement of the bolt in the movement path of the blocking element being prevented in at least one direction at one end of the bolt.
  • the end of the boom/bolt may, of course, include an opening in a way similar to that of a striking plate.
  • Movement of the boom/bolt in this path can be blocked by virtue of the cylinder or by virtue of a first latching device part carried by said cylinder, or by virtue of the locking pin carried by the cylinder or by said first part, when the cylinder is in a locking axial position.
  • the lock bolt coacts either directly or indirectly with a coacting device.
  • This coacting device may, for instance, be an electric switch or the like that is activated or deactivated when the lock bolt is in its locking position.
  • the coacting device may, alternatively, include a blocking means that is controlled for movement transversely to the movement direction of the bolt 3 and is adapted to be blocked with respect to movement in at least one direction along its movement path when the bolt is in its locking position, wherein the cylinder 3, or an element carried by the cylinder, or a part of the latching device carried by said cylinder 3, coacts with the blocking device. It will be seen from Fig.
  • a boom 7 is guided axially in a passageway 9 in a tubular element 90, said channel 9 defining a lateral opening into the housing 1.
  • the housing passageway 2 extends perpendicularly to the passageway 9 and receives the cylinder 3 and the latching device part carried thereby and referenced generally 40 in Fig. 9, wherein the latching tongue 22 is able to engage the recess 26.
  • the boom 7 has a boom-end 71 that can be moved in beneath the part 20 up to the housing wall, when the cylinder 3 is in its upper, non-locking position.
