Abstract

The invention relates to a lock, cylinder and key assembly which, by a set of suitable measures, makes it possible to obtain different lengths of travel of the lock bolt. Pins 1, 3 or projections are provided either on the key or on the outer perimeter of the cylinder or knob. When the key or the cylinder is rotated, these pins engage different contacts following their contact with stops located on the support surrounding the cylinder. The rotation of the cylinder through 360 DEG is thus prevented, which leads to a difference in travel of the lock bolt controlled by the cylinder. This system lends itself both to the reinforcement of a lock and to the design of a novel lock.

Description

The present invention is determined 10) On a device fixing on the interior entrance door
or exterior or both at the same time or being designed in the fa
latching of the lock. It is located exactly around the
cylinder or barrel for a door lock or any other
opening using a lock.

2) On the key of the door then modified not in the con
ception of the opening of the lock but in the part
free when ocllo-F1 c ,, t denr: 1st oy1tndr de lZ Lock dq
installed but can be designed during production, i.e.
between the visible throat and the head of the: key 30) Or by application of an assertor erator in this part
free between the tette and the groove abutting in the cylin
dre or the manufacture or reconstruction of a new key.

4) Or by the contribution of pins that can be made during the manufacturing
cannon or on the lock cylinder (horizontal or
vertical). In this case, it enters the second and
third category by the contribution of pins or gears.

This modification is none other than the contribution of ut or more
pins or teeth giving information from the turn of the key
causing the device placed on the door lock to
located exactly around the barrel or cylinder. By its action
rotary key, or button depending on the pins or teeth available
on the key or button drives the device put on
circular or ball slide. In some cases the key or
button can directly engage the contactors in its
movement without having help in some cases of lock the
need to put a slide.

The key or button thus modified goes into its slack
the contactors placed on the device, which can
give the desired information of the user according to the
keys used. The information thus collected can be
collected either by a central or electronic card whose
the functions of these can be multiple, example
heating regulation, power cut, power cut
valves, air conditioning regulation, telephone shutdown,
activation of the alarm device - (or directly
on the way by the spikes) .The different keys thus created
or designed during the manufacture of a lock with the available
sitive - either not their length, height or shape
protrusions or spikes in this process will give details
according to their respective use.

50) The stops that will be put in this device or on the cylin
dre manufacturing (or projection) along or above it will bring against the stop a difference in strokes
the slope according to the desired stroke length. This difference
can be obtained either by the key or the button
thus modified by the simple fact of turning the key or the bou
tone - the latter encountering a panic lying on the
device around the cylinder or barrel of the lock - the key
or the button by its rotation causing the commissioning of a
contactor and canceling it when unlocking the lock. The
bolt according to the desired length will engage at the bottom of the strike
a contactor - the latter giving iron information
meture or others.

This invention therefore offers the advantages of not
damage or change existing locks but simply
by modifying the key and setting up the system
fixed around the barrel or cylinder of the lock.

With the design of the lock, this system fits perfectly
lie around and at the ends or along the cylinder of a
lock.

Claims (6)

Patent Claims No. 8615460 1. Lock assembly, cylinder and key comprising a disposai ~ tif allowing the control of various mechanisms by limiting the length of the bolt stroke characterized by the presence of pins or projections (1,7,11,27,28,32,33 ) either on the type of the key, or on the outer periphery of the cylinder (27) or bou 'ton (32) which, when the key or cylinder is rotated, when opening or closing, engage different contactors (12,15,16,17,21,23,25) as a result of their encounter in the circular movement, with one or more stops located on a support (0) surrounding the cylinder: stop and pin prevent complete rotation (3600) of the cylinder therefore cause a difference in stroke of the bolt controlled by this cylinder. 2. Assembly according to claim 1 characterized in that the key carrying the pin or pins (3) is in one piece. 3. The assembly of claim 1 characterized in that the pins are located on the tip of a key in two rod elements (5) and tip (9) or button. 4. An assembly according to claim 1 characterized in that its manufacture is provided with one or more pins - the pin or pins are an integral part of the cylinder during its manufacture. 5. Assembly according to claim 1 characterized in that the lock is operated with several keys which differ by the location or the length of the pins (fig-4): the user of each of the keys, as a result of different contactors than they meet, allow, ldn of any maneuver, to identify the user. 6. The assembly of claim 1 characterized in that the cylinder has one or more fixed pins or shoulders (9,10,32) on the wall of the cylinder (over the entire length or not) above or inside ' the latter, or on one of the front faces or below at the level of the drive of the rack by the cylinder or above or below, on the rack pushing the bolt.
