  • the present invention relates generally to mortise lock assemblies and to features for convenient installation of mortise locks.
  • the mortise lock assembly is mortise fitted within a recess that opens at the side edge of the door, that is, the edge that, when the door is closed, abuts the adjacent surface of a door jamb. Because the main body of the lock including most of its operational parts is within the door itself, it is difficult for an intruder to gain access to those operational parts, thereby making it difficult for the intruder to gain unauthorized entry to a locked room or area.
  • a recess suitably configured for receiving the lock has to be created in the opening edge of the door.
  • the formation of the mortise is a relatively laborious process, and requires relatively precise positioning of the mortise relative to any strike or other object with which in use the lock is intended to cooperate.
  • a sensor device which is arranged to provide a signal to a remote point, the signal indicating whether the lock is in the locked or unlocked condition.
  • the sensor device is added to the lock on fitting, but that is a relatively laborious process.
  • a mortise lock assembly that is of simple construction but can nonetheless include a sensor device for monitoring whether or not the lock is in the locked condition.
  • the present invention seeks to provide an improved mortise lock assembly with features for the convenience of the installer or provider of mortise locks that address the abovementioned needs, as is described in detail further hereinbelow.
  • Some of the features include protrusions that help the person mark the aperture for installing the lock. Other features allow the installer to decide what spring strength to give the handle of the mortise lock without having to cany two different locks in stock. Another feature is an external sensor module that permits adding a microswitch or other sensor without having to provide it inside the lock.
  • a mortise lock assembly for a door including a casing, a locking mechanism arranged at least partly within the casing, and a plurality of location elements extending from the rear wall, for indicating a position for forming a recess in the door for receiving the lock assembly.
  • the location elements provided in accordance with the invention enable a location for forming of a recess within a side edge of a door to be marked by means of pressing the location elements against the side edge. Making use of the marks so formed, it is made possible for the recess to be formed relatively easily and quickly.
  • the use of the location elements to provide location marks, which can then be used as a guide for forming the recess, also allows the position of the recess to be determined with relatively high precision.
  • the location marks may be formed in any suitable way. Preferably, they are formed by means of forcing the lock assembly against the side edge of the door such that the location elements form recesses in the side edge. Any other suitable marking method may however be used.
  • the invention also provides a mortise lock assembly for a door, including a casing having a front faceplate and a rear wall opposed to the front faceplate, a locking mechanism arranged at least partly within the casing, the casing further including an upper wall and a lower wall, each extending from the faceplate to the rear wall and at least one of the upper and lower walls being of convexly curved configuration.

  • the invention also provides a lock assembly for a door, including a casing, a locking mechanism arranged at least partly within the casing and having a latch bolt, a handle, the handle being in operative connection with the latch bolt, a first spring assembly for applying a first return force to the handle, and a second spring assembly for applying a second return force to the handle.
  • a second spring assembly allows the return force acting upon the handle to be adjusted to meet desired or required conditions.

  • the lock casing also includes opposed side walls 4 and opposed upper and lower walls 5 and 6, respectively.
  • the lock assembly shown in the drawings is suitable for use in a variety of doors, for example, but not exclusively, in a sliding door. It includes a hook bolt 7, which is arranged in the vicinity of an aperture (not shown in the drawings) in the faceplate 2.

  • references to coincidence with the centre of one of the projections are in general to be understood as meaning that the centre is substantially coincident with a central region of a tip of the projection that, in use, causes a location mark to be generated on the side edge of the door. It is preferred for the tip of each terminal projection 17 1 - 17 7 to be centrally located with respect to an imaginary circle of which the respective arcuate edge 15 or 16 is a part because, in use, a cylindrical bore generated in the side edge of the door, centered upon a location mark made by the associated projection, and having a suitable diameter, will generate an internal surface that substantially corresponds to the curved outer configuration of the upper wall or the lower wall, respectively, of the casing. That arrangement serves considerably to simplify the fitting of the lock assembly into the door.

  • Reference numerals 20 and 21 indicate apertures for receiving screw fastening elements.
  • the rear wall 3 of the lock assembly is placed against the side edge of the door in the position in which the lock assembly is to be mounted.
  • the lock assembly is pushed against the side edge with sufficient force that a series of location marks is produced, one corresponding to each location element 17 1 to 17 7 .
  • a drill bit having a diameter substantially the same as the imaginary diameter of the arcuate edges can then be used to drill upper and lower bores, centered at the location marks at the top and the bottom, respectively, of the series of marks.

  • the intervening material of the door can then be removed by drilling bores of similar diameter centered upon the intervening location marks, resulting in a mortise that requires little or no further shaping to receive the lock assembly. In that manner, the recess can be formed simply, quickly, and with precise positioning.

Except for the ratchet edge 115 and the interaction with lever arm 114 further described below, the structure and operation of the latch bolt, the slidable member 113 and the associated spring 113a are essentially conventional and do not therefore require more detailed description.

Where the lock is manufactured with the sensor module in situ, all that the fitter is required to do is to fit the lock as normal. Where the lock is supplied with an empty casing module in place of the sensor module, the empty casing module can be removed and replaced by the sensor module. After attachment of the sensor module into the recess, the lock assembly can be fitted in the normal way.

Abstract

La présente invention se rapporte à un ensemble serrure à mortaiser pour porte, qui comprend un logement, un mécanisme de verrouillage disposé au moins partiellement à l'intérieur du logement, et une pluralité d'éléments d'emplacement s'étendant depuis la paroi arrière et destinés à indiquer une position permettant de former, dans la porte, un évidement conçu pour recevoir l'ensemble serrure. D'autres fonctions non limitatives permettent à l'installateur de la serrure de définir la puissance de ressort qui doit être conférée à la poignée de la serrure à mortaiser, tout en lui évitant de devoir transporter deux serrures différentes. Une autre fonction non limitative se présente sous la forme d'un module capteur externe, qui permet d'ajouter un microcontact ou un autre capteur sans que ces derniers doivent être placés à l'intérieur de la serrure.
