FR2748291A1 - CARENED LOCK WITH SEVERAL PENES AND MECHANISM OF SAFE HOUSES IN A SINGLE HOUSING - Google Patents

Abstract

The lock mechanism is mounted on the door and is located inside a housing made from U-section channelling elements. One element (1), attached to the door, is shorter than the full height of the door but is sufficiently long to enclose a common safety mechanism, and is covered by a trim strip in three sections (2a,2b,2c). All of the trim strip sections are made from U-section channelling large enough to fit over the first element (1), and its two outer sections (2b,2c) are able to slide inside the central one (2a). Two additional U-section elements (7,8) attached to the top and bottom of the door act as guides for the ends of the two outer sections of the trim strip. The first element (1) and the central section of the trim strip have holes (4,6,9,4',6',9') for the door handle, lock mechanism and bolts.

Description

The invention relates to a keeled lock consisting of a lock with

  a plurality of bolts actuated from a common safety mechanism via transmissions, the assembly being housed inside a single casing which can be attached to the leaf of a door, said casing being

  consisting of two interlocking profiles one of which forms the lid of the other.

  In order to constitute a housing that can be mounted on a door leaf, it is necessary to

  provide the two sections constituting the housing with dimensions adapted to the dimensions of this leaf.

  Thus, most of the time, the profiles are proposed long enough to be then cut according to the height of the door. In particular, all the keeled locks have at least one cover profile of the other, serving in particular decorative cover, which is cut according to the height of the door or which can even be cut in its lower part.

  to adjust the height of the axis. The installation of such a lock is therefore relatively complex.

  In order to overcome this drawback, the invention proposes a keyless lock for which the sections constituting the box enclosing the lock mechanism, as well as the linkage, are adjustable to the dimensions of the door on the leaf of which said box is applied without

that it is necessary to cut them.

  For this purpose, the subject of the invention is a keyless lock with several bolts actuated simultaneously from a common safety mechanism via transmissions, the assembly being housed inside a single case which can be the flap of a door, said casing being made up of two interlocking U-section cross sections, one of which forms the cover of the other, characterized in that the profile is applied to the leaf of the door has a shorter length at the height of the door leaf but sufficient to receive at least the common safety mechanism and the cover-decorating profile, forming a cover, is telescopic, said decorative cover profile consisting of a part of

  central section nestable on said sectional profile and two end portions nestable on said profile applied and slidable under the central portion of the decorative profile section.

  Thus, advantageously, the lock comprises a

  housing formed by the applied profile and a decorative trim profile whose length is adjustable according to the height of the door leaf against which the lock is placed.

  According to a characteristic of the invention, the keyless lock also comprises at least two brackets which are fixed at the top and at the bottom of the door leaf in the axis of the applied profile in order to guide the end parts.

  the decorative cover profile and the top and bottom closing points.

  The surface profile in which the lock mechanism is mounted and the decorative cover profile fitted thereon thus define a wall-mounted keyless lock casing whose thickness corresponds substantially to the thickness of the lock casing to which is added the thickness of the two sections. This provides a reduced thickness wall lock with good burglar resistance and which has the additional advantage of having a decorative edge profile whose length is adjustable in

  depending on the height of the door leaf.

  An embodiment of the invention will now be described with reference to the appended drawing in which: FIG. 1 represents an exploded perspective view of a lock according to the invention and FIG. 2 represents a plan view of the lock according to FIG.

  the invention mounted on a door frame.

  A faired lock according to the invention may comprise a safety mechanism actuating several bolts. In the example described, the lock has a high point and a low point as well as two lateral points. In particular, the up, down and side bolts can be actuated by

  movement transmission mechanisms between actuating rods, said rods extending between the central housing enclosing the safety mechanism. The actuation of the rods allows the locking and unlocking of all deadbolts.

  The safety mechanism is mounted in a casing made up of two interlocking U-section cross-sections, one being an applied profile 1 and the other being a cover-forming profile 2 forming a cover, nestable on the

profile 1.

  The applied profile 1 is intended to be mounted along the edge of a door 3 so that the bottom of the profile 1 is applied against the leaf of said door 3. As can be seen in the figures 1 and 2, the applied profile 1 has a length less than the height of the door leaf 3 on which it is placed but sufficient to accommodate the safety mechanism. For this purpose, the bottom of the applied profile 1 comprises an orifice 4 for the passage of a handle 5 and an orifice 6 for the passage of the mechanism cylinder, the door leaf 3 having also been drilled beforehand. holes

in correspondence.

  A wing 1b of the applied profile 1 has orifices

  9 allowing the passage of the side bolts.

  The applied profile 1 is then closed by the laying of the cachedécor 2 profile consisting of a first central portion 2a nestable on the applied profile 1 and two end portions 2b and 2c engageable on said applied profile 1 and slidable under the central portion 2a.25 The central portion 2a of the decorative trim profile 2 comprises, on its bottom 2a ', orifices 4' and 6 'for the introduction of the handle 5 and the cylinder of the lock while one of the wings 2a '' has orifices 9 'which are facing the orifices 9, 9' and 9 '' when the central portion

  2a of the decorative cover profile 2 is fitted on the applied profile 1.

  Preferably, the central portion 2a of the decorative cover profile

  2 and the applied profile 1 are substantially of the same length.

  In order to guide the end portions 2b and 2c that can slide, stirrups 7 and 8 are placed in the upper and lower parts of the door leaf 3, in the

  extension of the surface profile 1.

  The keylock lock according to the invention arises in the following way: the applied profile 1 is first fixed on the door leaf 3 along the edge thereof, for example

example by screwing.

  The applied profile 1, having a reduced length compared to the profile usually used, the positioning of the safety mechanism of the lock with respect to the height of the door is thus done

  simple according to the choice of the user or according to the bores already provided on the door leaf.

  In this applied profile 1 are then fixed

  safety mechanism, rods and interlocker, for example.

  The stirrups 7 and 8 are then fixed in the parts

  the upper and lower of the door leaf 3 in the extension of the sectional profile 1. Then the 25 points up and down by a threaded rod.

  Then, the end portions 2b and 2c of the decorative cover profile 2 are placed on the stirrups 7 and 8, respectively, said parts 2b and 2c fitting into the applied profile 1. Finally, the central portion 2a of the decorative cover profile 2 which fits on the applied profile 1 and

  partially covers the end portions 2b and 2c.

  As can be seen in FIG. 2, it is preferable to use as a striker a section 10 fixed to the frame and whose length is chosen, preferably from

  to match the length of the decorative trim profile 2.

  In the example shown, this profile 10 has at least one opening so as to allow the passage of at least one bolt. Preferably, this opening extends substantially over the entire length so that said opening can accommodate bolts of indifferent sections,

  whatever the positions of said bolts. It is of course also possible to use a striker profile comprising, in a traditional manner, through holes 10 adapted to the different bolts.

  As can be seen in FIG. 2, the ends of the profile 10 can be shaped such that they are in line with the ends of the central portion 2a of the decorative cover profile 2 when the door is closed, forming so a continuous line with said

  ends of the central portion 2a of the decorative cover profile 2.

  A striker 11 is provided on the upper part of the frame to accommodate the bolt high of the lock

  while the floor may also include a strike to accommodate the low bolt.

  It has thus been realized a keyless lock at several points, easily storable, transportable and posable.

  The different parts of the decorative cover profile 2 can

  be made in different colors.
