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 to any type of door such as: doors, gates, gates, said leaves being of wood, PVC, aluminum.

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

From this basic concept, various forms have been proposed of realization. The invention relates more particularly to a lock of type of that comprising a body in the form of two half-shells nestable. One of the half-shells receives an actuating mechanism in synchronism and locking a side bolt and two bolts vertically opposite, while the other half-shell acts as a cache. The half-shells have fixing arrangements between them and by relative to a part of the leaf considered. Vertical bolts can be coupled to cremones.

From this basic lock design, there are many models depending, for example, on the shape of the vertical bolts (form right or angled form), positioning to the right or to the left of the bolt side depending on the direction of opening .... It is conceivable 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 is done by turning the handle to the left, while naturally a locking action is performed by a movement to the right.

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

From this type of lock as defined, the problem that proposes to solve the invention is to be able, at will, and very easily change the vertical bolt or bolts in order to equip the lock, without particular dismantling of bolts of length and profile determined in depending on the type of locking elements that typically have to order said bolts.

EP-A-0 647 755 discloses a lock whose vertical bolts can be changed without special disassembly.

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

To solve these different problems, it was designed a lock according to the features of claim 1.

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

To solve the problem of having access to the means coupling or vertical bolts, the window is formed from one of the lateral edges at least of the half-shell and in the whole 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.

• soit deux pênes verticaux rectilignes, de forme générale rectangulaire ;
• soit deux pênes verticaux coudés, de forme générale équerrée ;
• soit un pêne vertical rectiligne de forme générale rectangulaire, l'autre pêne étant coudé, de forme générale équerrée.

Given these characteristics, it is possible to obtain a lock presenting, at will:

• either two rectilinear vertical bolts, of rectangular general shape;
• either two vertical bolts bent, generally squared form;
• or a rectilinear vertical bolt of rectangular general shape, the other bolt being bent, generally squared shape.

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

To solve the problem of being able to modify at will the overflow to the right or left of the side bolt, simply return from 180 ° the whole housing.

The invention is described below in more detail with reference to the figures of the accompanying drawings, in which:

• Figure 1 is a front view of the lock with a certain type of vertical bolts, the lateral bolt overflowing the right side of the body of the lock;
• Figure 2 is a side view corresponding to Figure 1;

The lock comprises 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 performed made of composite material, without excluding other materials. The half-shells (1) and (2) have any type of fastening arrangement between them and with respect to a part of the leaf or other to equip. One of the half-shells (1) receives an actuating mechanism in synchronism and locking a lateral bolt (3) and two opposite vertical bolts (4) and (5). The other half-shell (2) acts as a cover and holds in position of the mechanism. The case therefore has a generally rectangular and flat shape, which turns out to be important for the reversibility of the lock as it will be indicated in the following description.

As shown in the example of Figure 5 given as an indication in no way limiting, the mechanism essentially comprises a disc (6) rotated by a maneuvering square (8) of a handle (no shown). The operating disc (6) has, in overflow of one of its faces, two lugs cooperating with lights that present two rods (9) and (10) mounted with guided linear sliding capability in arrangements that the shell (1). In contrast to their coupling with the operating disk (6), the rods (9) and (10) are coupled to the vertical bolts (4) and (5).

In an important way, the coupling of the bolts (4) and (5) in end of the free ends of the rods (9) and (10), is effected by means of shoulder pins (11) and (12) freely engaged in through holes formed in the thickness of bolts (4) and (5) and ends corresponding control rods (9) and (10). Also note that the bolts (4) and (5) are mounted with linear displacement capacity guided in arrangements that presents the half-shell (1).

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

For this purpose, according to one of the features 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, presents retractable arrangements for access to said coupling means (11) and (12) bolts (4) and (5). For this purpose, the half-shell covering (2), has a window (2a) (2b) partially formed in its thickness and opening opposite the corresponding mating pin (11) and (12). Each of the windows (2a) and (2b) is closed by a plate (13) and (14) mounted with linear sliding capability guided in arrangements that presents each of said windows (2a) and (2b).

As shown in particular in the drawing figures, each window is formed from one of the side edges at least of the half-shell (2) on only part of that thickness to allow the free sliding of the plates (13) and (14). On the other hand, each of the windows (2a) and (2b) has an opening opening at the level of the pawn removable coupling (11) or (12).

So just to replace one or both vertical bolts (4) and (5), to remove the sliding plate (13) and (14) 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 being forced to dismantle the half-shell protection (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 or bolts (4) or (5), without dismantling the half-shells of the housing, the lock can be equipped with:

• or two rectilinear vertical bolts of generally rectangular shape (FIGS. 1 and 2);
• either of two bent vertical bolts of generally squared form;
• 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 control of the lateral bolt (3) is carried out by a pawn that presents, in overflow, the other face of the operating disk (6).

Or, in an advantageous way, and according to another characteristic of the invention, the lateral bolt is coupled to the mechanism actuating device, in particular to the operating disc (6), by a screw accessible from outside the half-shell (2) serving as hidden. These arrangements make it possible, without dismantling the half-shells (1) and (2), to properly position the side bolt (3) so that last overflows either to the right or to the left of the entire housing of the lock (Figures 1 and 3). Of course, the bolt (3) is arranged in result.

Of course, the whole mechanism as described is completed by a cylinder lock (15) and possibly a finger lock (16). In addition, the operating disk (6) is subject to a resilient return member via a guide finger.

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

As indicated, the locking and control mechanism as that described is shaped to be operated under a rotational effect directed to the right corresponding to a natural locking movement. In this goal and importantly, the different actuating elements of the mechanism that give the locking direction by turning to the right such as the cylinder (15), the lateral bolt (3), are located in the plane of symmetry of the housing defined by the assembly of the half-shells (1) and (2). Or well these elements are reversible, being interchangeable, without dismantling the case. As a result, it suffices to return the lock of 180 ° to position it, from one side or the other, depending on the direction of the opening the leaf to be equipped without changing 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 ;
• l'esthétique.

The advantages stand out well from the description, in particular one underlines and recalls:

• the possibility of proceeding, at will, the interchangeability of the vertical bolts in particular, without having to disassemble the half-shells;
• the possibility of overflowing to the right or left, the side bolt, for reversibility;
• the universal character and modularity of the lock;
• simplicity of realization;
• aesthetics.
