Abstract

The door lock comprises a rectangular, flat casing formed by two half shells (2) which are fitted into each other. One of the half shells receives a synchronizing activating locking mechanism for a lateral bolt (3) and two vertical opposite bolts (4,5). The connected vertical bolts can be dismantled from a part of the activating mechanism. The other half shell has retractable access fittings (13,14) to the bolts' coupling element (11,12). The half shells have fittings for the extension of the lateral bolt on one or other side of the half shells to allow a reversibility.

Description

The invention relates to the technical sector of locks intended for be applied on all types of leaves such as: doors, gates, gates, said leaves may be of wood, PVC, aluminum.

In a known manner, this type of lock essentially comprises a body in the form of a housing internally receiving a mechanism for control and locking of at least one sliding or pivoting bolt. The mechanism for moving the bolt (s) is generally subject to a control handle, while a cylinder actuated by a key ensures locking in: locking position of the bolt (s).

From this basic concept, we proposed different forms of achievement. The invention relates more particularly to a lock of the type of that comprising a body in the form of two half-shells nestable. One of the half-shells receives an actuation mechanism in synchronism and locking of a side bolt and two bolts opposite verticals, while the other half-shell acts as a cover. The half-shells have fixing arrangements between them and by relative to part of the leaf considered. The vertical bolts can be coupled with cremones.

From this basic lock design, there are many models depending for example on the shape of the vertical bolts (shape right or angled shape), positioning to the right or left of the bolt lateral depending on the direction of opening .... We can see that it is therefore necessary to have a number of types of locks particularly important.

It also appears that the lock command of the bolts are made by turning the handle to the left, while naturally a locking action is performed by a movement to the right.

The object of the invention is to remedy these drawbacks, simple, safe, efficient and rational way.

From this type of lock as defined, the problem proposes to solve the invention is to power, at will, and very easily change the vertical bolt (s) so that the lock can be fitted, without particular dismantling, of bolts of length and profile determined in depending on the type of locking elements that generally have to order said bolts.

We also wanted to obtain a universal lock in the sense that you can easily position the side bolt for closing on the right or left. Finally, we wanted closing and locking are carried out, by any known means, on the right.

Given the problem to be solved,

• the half-shells define a generally rectangular and flat case;
• the vertical bolts are detachably coupled to a part of the actuation mechanism mounted in one of the half-shells;
• the other half-shell has retractable arrangements for access by means of removable coupling of said bolts for their change, without disassembly of the half-shells;
• the half-shells have arrangements for the overflowing of the lateral bolt on either side of said half-shells in order to obtain reversibility;
• the various actuating elements of the mechanism which give the locking direction are located in the plane of symmetry of the housing defined by the assembly of the half-shells.

To solve the problem of interchangeability of the or vertical bolts, without particular disassembly of the constituent parts of the lock, in particular of the two half-shells, the fittings retractable access by means of coupling of the vertical bolts, are constituted by a window formed in the thickness of the half-shell acting as a cover and opening out opposite the coupling means, said window being able to be closed by a sliding mounted plate in arrangements of said half-shell.

To solve the problem of having access to the means of the vertical bolt (s), the window is formed from at least one of the side edges of the half-shell and in the entirety of its thickness at the coupling means and, from said edge, on only part of this thickness which corresponds to that of the sliding plate.

• or a rectilinear vertical bolt of generally rectangular shape, the other bolt being bent, of generally squared shape.

Advantageously, at least one of the vertical bolts has a hooking pin with an operating and / or locking rod of the cremone bolt type.

To solve the problem posed of being able to modify at will the overflow to the right or to the left of the side bolt, just turn it over 180 ° the whole case.

The invention is set out below in more detail with the aid of the figures of the appended drawings in which:

• Figure 8 is a view similar to Figure 7 showing the removal of the plate in order to have access to the removable coupling means of the corresponding vertical bolt.

The lock includes a body in the form of two half-shells nestable (1) and (2). Each half-shell has a general shape quadrangular, in particular rectangular, and is advantageously made made of composite material, without excluding other materials. Half shells (1) and (2) have any type of fixing arrangement between them and relative to a part of the leaf or other to be fitted. One of the half shells (1) receives a synchronous actuation mechanism and locking of a side bolt (3) and two opposite vertical bolts (4) and (5). The other half-shell (2) acts as a cover and keeps it in position of the mechanism. The case therefore has a generally rectangular and flat shape, which is important for the reversibility of the lock as it will indicated in the following description.

As shown in the example of Figure 5 given for information in no way limiting, the mechanism essentially comprises a disc (6) rotated by an operating square (8) of a handle (not shown). The maneuvering disc (6) has, in overflow from one of its faces, two pins cooperating with lights that have two rods (9) and (10) mounted with guided linear sliding capacity in arrangements presented by the shell (1). Opposite of their coupling with the operating disc (6), the rods (9) and (10) are coupled to the vertical bolts (4) and (5).

Importantly, the coupling of the bolts (4) and (5) in end of the free ends of the rods (9) and (10), is carried out by means of shouldered pins (11) and (12) freely engaged in through holes formed in the thickness of the bolts (4) and (5) and the ends corresponding control rods (9) and (10). Also note that the bolts (4) and (5) are mounted with linear displacement capacity guided in arrangements presented by the half-shell (1).

In view of these provisions, it follows that it suffices to remove the coupling pins to change the bolt (s) (4) and / or (5).

For this purpose, according to one of the characteristics of the invention, to have access to the removable coupling pins (11) and (12), the half-shell (2) being coupled to the half-shell (1) which receives the entire mechanism, said half-shell (2), which acts as a cover, has retractable arrangements for access to said coupling means (11) and (12) bolts (4) and (5). For this purpose, the covering half-shell (2), has a window (2a) (2b) formed partially in its thickness and emerging opposite the corresponding coupling pin (11) and (12). Each of the windows (2a) and (2b) is closed by a plate (13) and (14) mounted with linear sliding capacity guided in arrangements presented by each of said windows (2a) and (2b).

As shown in particular in the figures of the drawings, each window is formed from at least one of the side edges of the half-shell (2) over only part of this thickness to allow the free sliding of the plates (13) and (14). However, each of the windows (2a) and (2b) has a through opening at the level of the pin removable coupling (11) or (12).

It is therefore sufficient to replace one or both vertical bolts (4) and (5), remove the sliding plate (s) (13) and (14) in order to have direct access to the removable coupling pins (11) and (12) (Figures 7 and 8). It is thus possible to remove the pins (11) and (12), to remove the bolts (4) and (5) without having to dismantle the protective half-shell (2) (figure 8).

• soit de deux pênes verticaux rectilignes de forme générale rectangulaire (figures 1 et 2) ;
• soit de deux pênes verticaux coudés de forme générale équerrée ;
• soit d'un pêne vertical rectiligne de forme générale rectangulaire et d'un pêne coudé de forme générale équerrée (figures 3 et 4).

Given this possibility of being able to very easily change the vertical bolt (s) (4) or (5), without dismantling the half-shells of the housing, the lock can be equipped:

• either of two rectilinear vertical bolts of generally rectangular shape (Figures 1 and 2);
• either of two angled vertical bolts of generally squared shape;
• or a rectilinear vertical bolt of generally rectangular shape and a bent bolt of generally squared shape (Figures 3 and 4).

In addition, regardless of the combination chosen, the vertical bolts straight or angled can be of different length.

The side bolt (3) is controlled by a pin that is present, overflowing, the other side of the operating disc (6).

Or, advantageously, and according to another characteristic of the invention, the side bolt is coupled to the mechanism actuation, in particular to the operating disc (6), by a screw accessible from the outside of the half-shell (2) serving as hidden. These provisions allow, without dismantling the half-shells (1) and (2), to correctly position the lateral bolt (3) so that this last overflows either to the right or to the left of the entire housing of the lock (Figures 1 and 3). Obviously, the bolt (3) is arranged in result.

Obviously, the whole mechanism as described is completed by a cylinder lock (15) and possibly a finger lock (16). In addition, the operating disc (6) is subject to a elastic return member by means of a guide finger.

We also note that the vertical bolt (s) (4) and (5) can be fitted with a hooking pin (17) to cooperate with an operating and / or locking rod (not shown).

As indicated, the locking and control mechanism as that described is shaped to be actuated under a directed rotation effect to the right corresponding to a natural locking movement. In this purpose and importantly the different actuating elements of the mechanism which give the locking direction by turning to the right such as the cylinder (15), the side bolt (3), are located in the plane of symmetry of the housing defined by the assembly of the half-shells (1) and (2). Or these elements are reversible, being interchangeable, without disassembly of the housing. As a result, it suffices to turn the lock 180 ° to position it, on one side or the other, depending on the direction of the opening considered of the leaf to be fitted, without modifying the operation of the lock.

• la possibilité de faire déborder à droite ou à gauche, le pêne latéral, en vue d'une réversibilité ;
• le caractère universel et le caractère modulable de la serrure ;
• la simplicité de réalisation ;

The advantages clearly emerge from the description, in particular it is emphasized and recalled:

• the possibility of proceeding, at will, with the interchangeability of the vertical bolts in particular, without being obliged to dismantle the half-shells;
• the possibility of causing the lateral bolt to overflow on the right or on the left, with a view to reversibility;
• the universal and modular nature of the lock;
• simplicity of implementation;
• aesthetics.
