Both lock and catch plate have covers (13) that fit over the back plates and are fixed to the flanges by screws inserted through holes (38) in the sides of the covers that are concealed and inaccessible when the door is closed and locked.

Description

The present invention relates to a lock of the type comprising:

  an elongate bolt in a longitudinal direction; an approximately parallelepipedal box having a longitudinal end wall and four side walls bordering the end wall, at the rate of two transverse lateral walls, at least one of which is traversed longitudinally by a passage for the bolt; and two longitudinal side walls, the four side walls having, opposite to the front wall, free edges bordering an open face of the trunk, a shutter plate of said open face, defining a closed enclosure with the trunk, means for releasably interconnecting the trunk and the closure plate, means for guiding the bolt to the longitudinal translation with respect to said enclosure, mechanical means for actuating the bolt for longitudinal translation between a plurality of predetermined positions, with respect to said enclosure, from outside of it, said mechanical means maneuvering through respectively the front wall of the housing and the closure plate, - a lock mechanism housed in said enclosure, controlled by the mechanical means of maneuver the bolt and correspondingly controlling the longitudinal translation of the bolt of one to the other of said determined positions, relative to said enclosure, means for fixing said enclosure to an opening.

  2891568 2 Locks of this type, intended to be mounted on one side of an opening, namely generally its side facing towards the inside of a room to be protected, but capable of being actuated both from that side and from the opposite side of the opening, through it, are widely spread, in an embodiment in which the bolt guide means, at least the mechanical means of maneuvering thereof through the front wall of the housing, intended for actuation from the mounting side of the lock and constituted as appropriate by a rotary knob or by a lock barrel authorizing the operation by introduction and rotation of a key, and the lock mechanism are carried jointly by the chest, while the mechanical means of maneuvering the bolt through the shutter plate and through the opening, constituted by another lock barrel through it and also allowing the maneuver by i ntroduction and rotation of a key, are possibly carried by the shutter plate. In this known embodiment, the fastening of the bolt to an opening is ensured by four screws which pass through the front wall perpendicularly to one another through a respective hole which is arranged at a respective corner of this end wall. and around which a head of the screw bears on the latter, while a rod of the screw passes through the entire closed enclosure that delimit together the closure plate and the trunk, and the plate of shutting by a respective large notch arranged in it, to screw into the opening. The shutter plate is in turn secured to the trunk by screws 2891568 3 generally hidden by the opening after fixing the latch thereon.

  Such locks are appreciated for their robustness and reliability but, in this known embodiment, they have a number of disadvantages.

  One of these disadvantages, of aesthetic order, results from the fact that the heads of the fastening screws to the opening are necessarily visible at the four corners of the front wall of the trunk, and all the less discreet that they present a dimension in relation to the diameter of the screw, for example of the order of 5 mm, as dictated by a concern for solidity of attachment to the opening.

  In addition, it is particularly difficult to screw the fastening screws to the opening in a strictly determined orientation, that is to say in practice perpendicular to the opening, insofar as they are guided only by the hole which allows the crossing of the front wall and have a length cantilever relatively large on both sides of this hole. However, even a slight inclination of a screw, in comparison with a rigorous perpendicularity with respect to the opening, results in a defective positioning of the screw head relative to the front wall of the trunk and, even if the latter presents around the hole a proper milling to receive the screw head when properly positioned, this positioning defect is unsightly, and can cause the head to overtake aggressively milling.

  In addition, the length that the screws necessarily have in door-to-bars between the front wall of the trunk and the opening makes them work in poor mechanical conditions and, in particular, makes them vulnerable to sagging during a forcing attempt. latch by rotation or translation thereof on the leaf. Indeed, such an attempt results in the application of forces to the screws in the immediate vicinity of their head, to their crossing of the front wall, that is to say cantilevered with respect to their screwed part in opening it, and involves the application of important moments to the screws.

  Finally, if it is desired to offer customers different types of boxes, for example a brushed or polished metal appearance, or an aspect lacquered or anodized in different colors, or different forms of trunk, to allow each customer to adapt the aesthetics of the lock to his tastes and to harmonize with a set to which it must integrate, it is necessary to manufacture and keep in stock as many complete locks as different aesthetics, which is cumbersome and expensive and in fact reduces the choice offered to customers.

  The object of the present invention is to remedy these drawbacks and, for this purpose, the present invention proposes a lock of the type indicated in the preamble, characterized in that: - the means for guiding the bolt, the mechanical means for operating the bolt and the lock mechanism are integrally carried by the closure plate, which furthermore has the fastening means to an opening, in that the fastening means to an opening comprise holes passing through the shutter plate perpendicularly to this, for the passage of fastening screws of the shutter plate, flat on the opening, in conditions such that heads of these screws are supported on the shutter plate at the edge of said holes of that and in that the means for mutually detachable connection of the trunk and the closure wall are accessible from outside said enclosure, by at least one of the walls of the trunk.

  Thus, the heads of the screws used to secure the lock to the opening, regardless of the size of these screws, chosen according to mechanical strength requirements, appear only on the blanking plate, that the it is fixed on the opening before attaching the trunk, then they are hidden by the latter which, against against the removable fastening to the closure plate must be just sufficient to immobilize the trunk with respect thereto and can be achieved by discrete means, such as small screws, placed in locations chosen to be themselves discrete, for example on the side walls of the box, whose front wall can have any desired aesthetic, free of screw holes and screw heads.

  In addition, the screws used for fixing to the opening can be much shorter, since they must not cross the distance between the front wall of the trunk and the blanking plate mutually, so that they work in better mechanical conditions, without cantilever, including during an attempt to rip the lock against the sash, and that they are more generally less prone to sag. Given their smaller length, in comparison with the screws usually used for fixing a bolt on an opening, they can be more easily screwed in an orientation perpendicular to the opening and, if they come to tilt, this has no effect on the aesthetics of the lock since their heads are hidden by the trunk after placing it on the shutter plate.

  It also becomes possible to offer a wide choice of trunk aesthetics to customers, since it becomes possible to store on the one hand identical sealing plates, having the same means of guiding a bolt, the same means of operating a bolt, the same lock mechanism, the same fastening means to an opening and the same means of removable connection with a trunk, in a standardized way, and secondly a range of safety boxes. different aesthetics, all adapted to be secured in a removable manner with the shutter plate and standardized.

  To facilitate the establishment of the trunk on the closure plate after attachment thereof to an opening, it is preferably provided that the passageway arranged in at least one of the transverse lateral walls of the trunk for the bolt is open towards the corresponding free edge, which is made possible by the fact that this passage is devoid of any guide function of the bolt, unlike similar passages lock chests according to the prior art.

  Naturally, a lock according to the invention is compatible with any type of mechanical means for actuating the bolt and, as in the prior art, the operating means passing through the closure plate may advantageously comprise a first lock barrel, borne jointly by the shutter plate and having a determined transverse axis, perpendicular thereto, while the operating means passing through the front wall can be selected from a group comprising a button, this time carried by the shutter plate and guided the rotation, relative thereto, about a given transverse axis, perpendicular thereto, and a second lock barrel, also integrally supported by the closure plate and having a determined transverse axis, perpendicular to this, it being understood that these different transverse axes can be confused or mutually parallel.

  The arrangement, according to the present invention, the fastening means of the latch to an opening in the form of holes through the shutter plate perpendicularly thereto, for the passage of screws for fixing the shutter plate, flat, on the opening, and the fact that these through holes as the heads of the screws that pass through them are therefore hidden by the trunk once it secured in a removable manner with the closure plate, allow to to overcome any aesthetic concern in the shape of the holes, which offers a lock according to the invention unknown possibilities with the locks of the same type currently known. Indeed, one can choose to give these holes a configuration certainly quite unsightly, but suitable to allow the replacement of a conventional lock already installed but failed, by reusing the holes for receiving the fixing screws thereof in opening it to receive the fastening screws of the locking plate of the lock according to the present invention, and reusing the hole arranged in the opening, in the past, to receive the barrel of the conventional lock failed to house the first barrel of the lock according to the invention.

  For this purpose, according to a preferred embodiment of the locking plate of the lock according to the invention, the holes passing through it for the passage of the fastening screws, flat, on the opening, are divided into two groups which are mutually symmetrical with respect to a determined transverse plane including the axis of the first barrel and each of which has two holes which occupy a respective position determined on the one hand perpendicular to said transverse plane and on the other hand perpendicular to a determined longitudinal plane including the axis of the first barrel and have a respective determined contour, oblong perpendicular to said longitudinal plane, said position and said contour of each hole being determined so that each hole closely surrounds the positions and contours of the respective one of the screws fastening, to an opening, various different types of conventional lock comprising a lock barrel similar to said first barrel, substantially identical position of the axis of this similar barrel and the axis of said first barrel.

  It has been possible to determine, from the conventional locks on the market, that it is thus possible not only to make the contour and the position of the holes clean for this purpose, but also to determine said position and said contour of each hole of such that is established between the contours of two holes disposed on the same side of said longitudinal plane and the corresponding screws for fixing the closure plate, flat, on the opening, respectively occupying the position of a screw for fixing a conventional latch of any one of said types, a stop contact against a rotation of the shutter plate respectively in one direction or the other, about the axis the first barrel, compared to the opening.

  The terms stop contact here must be understood with a certain degree of tolerance, a game of a few tenths of a millimeter, respectively in one direction and in the other, between the rod of each screw and the hole which receives it in the plate. shutter, after screwing the screws to the bottom, being admitted as establishing yet such a stop contact.

  Thus, since a respective screw is engaged in each of the two holes in question, the position of the shutter plate, that is to say of the entire lock, relative to the opening is fixed by the cooperation between each of these screws and the corresponding hole of the shutter plate and by the cooperation between the first barrel and the hole which, in the opening, receives it after receiving a corresponding barrel of the previous conventional latch.

  Naturally, this assumes that this hole of the opening is large enough to receive the first barrel of the lock according to the invention, while the corresponding barrel of the traditional type of lock replaced by a lock according to the invention may itself present different dimensions, according to which this hole was built.

  To increase the universality of the lock according to the invention, that is to say to allow it to replace a maximum of conventional locks, it is preferably provided that the first barrel has, with reference to its axis, a cylindrical outer periphery of revolution with a diameter of value at most equal to the smallest diameter value of an outer periphery that said similar conventional lock barrel has in reference to its axis.

  The various arrangements making it possible to use a lock according to the invention in place of a conventional lock by reusing the fixing holes and the hole for the passage of the barrel previously arranged in the opening can lead to visible dissymmetry of the plate. shutter relative to the longitudinal plane including the axis of the first barrel, and it is understood that a person skilled in the art can easily determine, by observation or even by test, the orientation to be given to the shutter plate, around the axis of the first barrel, to coincide each of the holes thereof with the receiving hole of a fixing screw of a conventional lock to be replaced, but it can further facilitate this operation by providing that the plate of shutter has tracking means in orientation about the axis of the first barrel.

  A person skilled in the art will readily understand that the aesthetic and mechanical disadvantages that are encountered with locks of traditional design are found with traditional design locks, simply consisting of a hood similar to the trunk of the lock and , like him, screwed on a frame receiving the opening by means of four screws passing through a front wall at the four corners thereof, and that a strike of traditional design would generally combine poorly with a lock according to the invention .

  The present invention therefore proposes an assembly comprising, in addition to a lock according to the invention, a striker intended to cooperate with such a lock, this assembly being characterized in that the striker comprises, with reference to a position of cooperation with said latch: a base plate extending the closure plate, having holes which pass therethrough perpendicular to it, for the passage of screws for fixing the base plate, flat, on a frame, under conditions such that these screws are supported on the base plate at the edge of said holes thereof, and integrally carrying a transverse flange turned towards the latch and traversed longitudinally by a receiving light of the bolt, closed in any transverse direction, - an approximately parallelepipedal cover , having a longitudinal front wall and four side walls bordering the front wall, with two side walls tr ansversales at least one is traversed longitudinally by a passage for the bolt and two longitudinal side walls, the four side walls having opposite the front wall of the free edges bordering an open face of the hood, - means of releasably interconnecting the cover and the base plate, in a relative position in which the cover surrounds the base plate, the free edges of the side walls surrounding the base plate and said at least one transverse wall along the rim thereof; ci, said removable mutual interconnection means of the cover and the base plate being accessible by at least one of the walls of the cover.

  The advantages of such a waste, in comparison with the strikes of the prior art, are in all respects similar to those of a lock according to the invention, in comparison with a conventional lock, and the assembly according to the invention thus offers, homogeneously, all these advantages over similar sets of the prior art.

  Preferably, to allow to re-use the holes for receiving the fastening screws of a traditional striker to fix the striker of an assembly according to the invention on a frame, and taking into account that the holes provided in the base plate of this striker to receive the screws used for this purpose are hidden once the cover removably secured to the base plate, it is preferably provided that the holes of the base plate are divided into four groups of at least one hole , which are mutually symmetrical with respect to a given transverse plane of the base plate, occupy a determined position perpendicular to said transverse plane of the base plate and at a predetermined longitudinal plane of the baseplate, perpendicular to said transverse plane, and have a respective determined contour, oblong perpendicular to said longitudinal plane of the base plate, said position and said contour of each group of at at least one hole being determined such that each group of at least one hole closely surrounds the positions and contours of a respective one of the fastening screws, at an opening, of at least most of the different types of waste conventional, associated with said determined types of conventional latch.

  The resulting advantages can be easily deduced from the advantages that result from a similar design of the locking plate of the lock according to the invention.

  Naturally, it is possible for each group of at least one hole in the base plate of the keeper to tightly envelope the positions and contours of a respective one of the fastening screws of all associated conventional striker types. to said determined types of conventional lock, to which a lock according to the invention can be substituted without repering the opening, but it has emerged that two of the fixing screws of these conventional strikes are, in rare cases, disposed much too close to the rebate of the frame to provide security against a burglary by tearing of the striker. When this is the case, it is preferred to fix the base plate of the striker associated with a lock according to the invention by means of screws placed further from the rabbet of the frame, through the holes of this base plate, then provided for include only the positions and contours of the conventional waste attachment screws furthest from the rebate of the frame; the frame must then be reperforated in suitable locations for this purpose, but the position and the contour of each hole or group of holes in the base plate of the striker make it possible to sufficiently distance the holes thus drilled from the receiving holes of the screw for fixing a conventional striker previously installed so that it does not result in mechanical weakening of the frame; on the contrary, the substitution of a latch-striker assembly according to the invention to a latch-striker assembly of the prior art makes it possible to benefit from increased security against burglary by tearing the striker.

  In addition, to allow to associate the same striker to a lock according to the invention both in opening to the right opening left, according to the conventional name, simply by reversing the position of the striker relative to the lock, one advantageously provides that the groups of at least one hole of the base plate of the striker are further mutually symmetrical with respect to a predetermined longitudinal plane of the base plate, perpendicular to said transverse plane thereof. It can certainly result in an increase in the transverse dimensioning of the groups of at least one hole, as will be readily understood by a person skilled in the art, but this has no aesthetic consequence since these groups of holes are hidden once the hood of the striker has been fixed. to the base plate of it.

  Other features and advantages of a latch and a latch-striker assembly according to the invention will become apparent from the description below, relating to a nonlimiting embodiment, as well as the accompanying drawings accompanying this description.

  FIG. 1 shows a perspective view of a latch and a striker according to the invention, as they appear when they are installed respectively on an opening leaf in the closed position and on a frame, while the bolt occupies an unlock position.

  Figure 2 shows a view similar to that of Figure 1, while the trunk of the lock is disassembled but presented opposite the shutter latch plate and the latch cover removed.

  Figure 3 shows a similar view, while the boot has been removed and the keeper has been removed but remains in position opposite the strike plate.

  Fig. 4 shows a plan view of the closure plate and the base plate in a relative position corresponding to that of Figs. 1 to 3, showing the silhouette of the lock box and the latch cover. in position respectively on the shutter plate and on the base plate and the silhouette of the bolt in an unlocked position relative to the striker.

  FIG. 5 shows a plan view of a conventional latch and striker, for purposes of highlighting the dimensions useful for comparison with a latch and striker according to the present invention, for the purpose of replacing such a latch and such a striker 10 according to the invention to a conventional latch and striker with reuse of the screw holes respectively to the sash, in any case, and to the frame, in most cases.

  FIG. 6 shows a plan view, on a larger scale, of the closure plate of the lock according to the invention, illustrating the conformation of the screwing holes thereof to the opening and the corresponding respectively positions of the screws, engaged in pre-existing screw holes, corresponding to the screwing of a conventional bolt initially in place, any one of sixteen types, determined widespread, with preservation of the position of the barrel axis passing through the opening.

  FIGS. 7 to 22 show plan views, similar to that of FIG. 4, of a latch and a striker according to the invention, of which, respectively, the shutter plate and the base plate are fixed by means of screws located in the fixing holes previously used for fixing the sixteen types of lock mentioned above and most associated strikes, with illustration of the positioning of the screws in each case.

  It will be noted that FIGS. 1 to 4 and 6 to 8 thus illustrate different components of a lock 1 according to the invention and a keeper 2 according to the invention, in a preferred embodiment, compatible with a substitution of a such latch and such a latch to a conventional latch and striker, one or the other of various types determined widely on the market, with reuse, for this purpose, on the one hand holes arranged by the passed in the opening for the installation of conventional lock to replace, cleared due to the removal of it, to receive the bolt fixing screws 1 and the lock barrel through the opening and secondly, in to the extent that they are not too close to the rebate of the frame, holes previously made in it for the installation of the conventional striker to replace, cleared because of the removal of the latter, to receive the striker fixing screws 2. The screws of f Attaching the striker and the lock according to the invention, respectively to the opening and to the frame, can thus occupy different positions, in a view of the striker and lock in the direction of the screws.

  It is understood, however, that one could also achieve in accordance with the present invention a latch 1 and a latch 2 whose fixing screws respectively to the opening and to the frame could occupy a single respective position, in retaining, however, the provisions which, in accordance with the present invention, attribute all the technical functions to the lock plate of the latch and the base plate of the striker, and assign to the trunk of the latch and to the cover of the striker that a cache role. A person skilled in the art will bring without difficulty, to the arrangements that will be described, the simplifications resulting from such a choice.

  Whatever the method of attachment thus chosen, the latch 1 and the keeper 2 according to the invention respectively comprise a shutter plate 3 and a base plate 2, intended to be contiguous flat respectively to an opening not shown and to a dormant not shown and fixed to the latter in a specific relative position which will serve as a reference in the following description, before receiving, securely but removably, respectively a chest 13 and a cover 74 constituting simple covers. When, as is common, the bolt 1 equips the opening of a door

  and the striker 2 the frame of this door, the two plates 3 and 4 are vertical and, for simplicity, we will refer to such orientation, although a latch and striker according to the invention can be used in any which orientation, such as conventional locks and strikes, as will be readily understood by a person skilled in the art.

  With reference to such an orientation, the shutter plate 3 is defined by two main plane faces, mutually parallel and here vertical, with one face not visible in the figures, intended to stick flat to the opening, and a face 5 intended to be turned away from the opening.

  These two main faces such as 5 have an approximately rectangular contour, defined by two rectilinear and mutually parallel edges 6, here vertical, and two edges 7 and 8 mutually parallel and perpendicular to the two edges 6, namely here horizontal, the edge 7 constituting a higher song and singing 8 a lower chant. Each of the songs 7 and 8 is connected to each of the songs 6 by a respective rounded corner, not referenced.

  The songs 6 are longer than the songs 7 and 8 and have a plan 9 of mutual symmetry, here vertical, which will appear later that it constitutes a plane of symmetry for the shutter plate 3 in its entirety, then that the songs 7 and 8 define a plane 10, here horizontal, of mutual symmetry, which will appear later that it does not constitute a plane of symmetry for the shutter plate 3 considered as a whole.

  Along its two edges 6, the shutter plate 3 is connected integrally, for example by one-piece production stamped from the same metal blank, to a respective flat flange 11, forming a protrusion at right angles to the face 5, and the two flanges 11 are mutually identical, mutually symmetrical with respect to the plane 9 to which they are parallel, and respectively symmetrical with respect to the plane 10.

  When seen in one direction or the other in a direction perpendicular to the plane 9 and subsequently considered longitudinal, the two flanges 11 present in the illustrated example a respective contour in the form of an isosceles trapezium, whose large base is defined by their integral connection to the corresponding edge 6 of the closure plate 3, but this form is only a non-limiting example, although it is currently preferred insofar as it corresponds to a minimum space requirement flanges 11 and therefore the possibility of associating with the closure plate 3 chests 13 of very different conformations, chosen as freely as possible.

  In the longitudinal direction 12, each flange 11 is pierced right through a respective passage 14 of rectangular contour, symmetrical with respect to the plane 10, the two passages 14 being furthermore mutually symmetrical with respect to the plane 9.

  The two passages 14, mutually identical, are arranged so that the long sides of their rectangular contour are parallel to the face 5 of the closure plate 3 and the short sides of their rectangular contour perpendicular to this face 5, and constitute guides, sliding in the direction 12, for a longitudinal bolt 15 having perpendicular to this direction 12 a rectangular section, complementary to the contour of each of the passages 14, and in the direction 12 a longitudinal dimension much greater than that which separates the flanges 11 perpendicular to the plane 9 so that the bolt 15 can evolve, by longitudinal sliding inside the passages 14, maintaining a rigorous guidance with respect to the closure plate 3, from one to the other several fixed positions, at the rate of at least two limit positions, mutually symmetrical with respect to the plane 9 and in which, respectively: - as illustrated in Figures 1 to 4 and 7 to 22, and in relation to the relative positioning chosen for the latch 1 and the striker 2, which is to the right of the lock 1 in these figures , the bolt 15 forms to the left of the rim 11 on the left a projection greater than to the right with respect to the rim 11 on the right, which corresponds to a limit position of unlocking or opening, in which the bolt 15 is cleared of the striker 2, and which would constitute a locking or closing position if the striker was disposed to the left of the latch, not shown, and, conversely, not shown, the bolt 15 forms to the right of the rim 11 of a larger protrusion to the left of the rim 11 on the left, which corresponds to a closed position, in which the bolt 15 engages the striker 2, but would constitute an open position if the striker 2 was located to the left of the verr or 1.

  Indeed, in a preferred manner which will be detailed later, the striker 2 is designed to be placed on one side or the other of the latch 1, with the latch 2 turned over without turning the latch 1, to allow the adaptation of the same latch-striker assembly according to the invention to the case of opening to the left and opening to the right, according to the conventional denomination.

  In contrast to their connection to the closure plate 3, that is to say along the small base of their trapezoidal contour in the illustrated example, the two flanges 11 bear solidarity, for example by recess in each of them and nip between them, a spacer 16 flat, parallel to the closure plate 3, this spacer 16 is spaced sufficiently to define with it, between the two flanges 11, a housing 17 for receiving a lock mechanism 18 adapted to cause, in a controlled manner, a longitudinal translation of the bolt 15 from one to the other of its determined positions, with respect to the flanges 11 and to the closure plate 3.

  In a manner characteristic of the present invention, just as the bolt 15 is carried and guided, by means of the flanges 11, by the shutter plate 3, the lock mechanism 18 is carried, via the spacer 16 and flanges 11, by the shutter plate 3.

  The lock mechanism 18 is of conventional type, well known to a person skilled in the art, and will not be described further.

  This lock mechanism 18 is itself controlled, with a view to the translation of the bolt 15 from one to the other of its determined positions, by mechanical means of maneuvering from outside the lock 1, that is to say from the outside of an enclosure 19 which includes the housing 17 and that the box 13 delimits with the closure plate 3 when they are mutually assembled, under conditions which will emerge from the rest of the

description.

  Characteristically according to the present invention, these mechanical means of maneuver are themselves borne by the closure plate 3, respectively directly and via the spacer 16 and the flanges 11.

  More specifically, to allow a maneuver of the bolt 15 from inside the room in which are the lock 1 and the striker 2, the spacer 16 carries as a means of actuating the bolt 15 a knob 20 mounted on it, by means not shown but the realization of which falls within the normal abilities of a person skilled in the art, relative rotation about a transverse axis 21 perpendicular to the shutter plate 3 and for example located at the intersection of the planes 9 and 10.

  On the side of the opening 2, opposite to the shutter plate 3 with respect to the button 20, these actuating means of the bolt 15 are constituted by a lock barrel 22 borne integrally, directly, by the plate of shutter 3 and having an outer periphery 23 cylindrical of revolution about an axis 24. This axis 24 could merge with the axis 21 if the barrel 22 guided coaxial rotation a key receiving rotor 25, according to a known arrangement and not illustrated, but, in the illustrated example in which the rotor 25 is guided to rotation about an axis parallel to the axis 24 of the barrel 22 and that is made to coincide with the axis 21, according to a other known arrangement, the axis 24 is parallel to this axis 21, located as it in the plane 9 but shifted towards the upper edge 7, relative to the axis 21, a distance hl dictated by the type of gun 22 chosen, and for example of the order of 4 mm for a diameter Dl of the outer peripheral face 23 of 22 higher barrel equal to 23 mm, these figures are provided as merely a non-limiting example, but corresponding to the currently preferred values.

  As will be readily understood by a person skilled in the art, the button 20 could be replaced by a lock barrel in all respects similar to the barrel 22 and as for it carried integrally by the spacer 16, in a position such that the axis of its rotor coincides with the axis 21, which would coincide the axis of its outer periphery with the axis 24. This solution has not been illustrated, but its adoption instead of the knob 20 is within the normal capabilities of a Skilled person.

  The shutter plate 3 thus collects all the mechanical provisions of the lock 1 and may include any other favorable arrangement for this purpose. Thus, in the illustrated example, it has near its upper edge 7 a lug 26 cut in it and folded at right angles to form a projection on the face 5, above the housing 17, a lower distance to that of the projection formed by the flanges 11, and this lug 26 towards the housing 17 a not referenced boss receiving a not shown spring applying a downward thrust, and to a locking position of the bolt 15, a not shown groove of the mechanism 18 lock, a way in itself well known to a skilled person. This tab 26 has been omitted in Figures 4 and 6 to 22, for the sake of clarity of the drawing, but it is understood that the shutter plate 3 shown in all of the figures is the same.

  In addition, in a manner also characteristic of the present invention, it is the shutter plate 3 which has the fastening means of the latch 1 to the opening, in the form of four holes which pass therethrough perpendicularly, to receive screws fixing the shutter plate, flat, on the opening, which holes are arranged respectively close to each of the corners of the closure plate 3 and distributed, in a manner which will be detailed later, in two groups mutually symmetrical with respect to the plane 9 and each of which comprises, respectively close to the upper edge 7 and near the lower edge 8, an upper hole 27 and a lower hole 28.

  The box 13 is thus devoid of any mechanical function, and is a simple cover that is fixed removably on the sealing plate 3 after screwing the latter, in a definitive position, on the opening.

  In connection with such an assembly order, the box 13 is connected to the shutter plate 3 by means of mutual removable connection which must remain accessible from outside the enclosure 19 delimited by the box 13 and the plate shutter 3 after fixing the latter to the opening.

  In the illustrated example, these detachable mutual fastening means comprise, on each of the flanges 11, two tapped holes or holes that can be tapped by a self-tapping screw, with a respective hole 29 disposed above the passage 14 corresponding and a respective hole 30 disposed below this passage 14 corresponding. The two holes 29 are aligned along the same longitudinal axis, not illustrated, as are the holes 30, and these two axes are mutually symmetrical with respect to the plane 10 to allow mounting of the box 13 on the blanking plate 3, regardless of in two mutually angularly offset orientations of 180 about the axis 21.

  This box 13 has a shape that allows it to fit on the closure plate 13, namely in particular on the edges 11 thereof, concealing the holes 27 and 28 as well as the lock mechanism 18, but this shape can also be chosen freely, regardless of any function for example of guiding the bolt 15 in its longitudinal translational movement or the knob 20 in its rotational movement.

  However, it retains a shape close to the traditional form, namely an approximately parallelepipedal shape, defined by: an approximately planar front wall 31, for example slightly convex towards the outside of the enclosure 19 as illustrated, which wall 31 is disposed approximately parallel to the shutter plate 3, opposite it with respect to the spacer 16 that this front wall 31 covers, allowing a free passage of the button 20, for its maneuver from outside the enclosure 19, in the form of a simple hole 32 coaxial with this button 20 if one refers to a state of the lock 1, as illustrated in Figure 1, wherein the trunk 13 is fixed to the closure plate 3, and - four side walls bordering the end wall 31 on the same side thereof, turned towards the closure plate 3, due to: E two transverse side walls 33, flat, mutually parallel, of which one is bordered by a free edge 35 opposite its connection to the wall 31 and traversed longitudinally by a passage 34 for the bolt 15, which passage 34 is devoid of any guide function of the bolt 15, contrary to Art prior, and can therefore advantageously be open towards the corresponding free edge 35 to facilitate the establishment of the trunk 13 on the closure plate 3 or its separation vis-à-vis thereof, these two walls 33 being mutually spaced from a longitudinal distance substantially identical to that which separates the unreferenced faces of the flanges 11 turned in the direction of a distance from the plane 9, so as to allow the establishment of the trunk 13 on the plate 3 or its disassembly vis-à-vis thereof by relative sliding of the walls 31 and the flange 11, and E two longitudinal side walls 36, having the opposite of their connection to the front wall 31 a respective free edge 37, the free edges 35 and 37 complement each other, in the same geometrical plane coinciding with that of the main face of the shutter plate 3 opposite its face 5 when the box 13 is assembled to the plate shutter 3, for flanking an unreferenced open face of the trunk 13, by which the trunk 13 fits on the closure plate 3 by matching the edges 6, 7, 8 thereof, where appropriate with a certain peripheral clearance as can be seen from the examination of FIGS. 4 and 7 to 22 in which the trace of the side walls 33 and 36, that is to say of their free edges 35 and 37 around shutter plate 3.

  This, however, essentially closes the enclosure 19 which it defines with the chest 13 when the latter is assembled.

  With a view to this assembly, in positions which coincide coaxially respectively with each of the holes 29 and each of the holes 30, each of the transverse lateral walls 33 of the box 13 is pierced with a respective hole 38, 39 which, if the box 13 is symmetrical with respect to the planes 9 and 10 once it is assembled to the shutter plate 3, can be placed indifferently in front of a hole 29 or in front of a hole 30 by simply turning the trunk 13, 180, around the axis 21, by reason of symmetry.

  It will be observed that the heads of the screws ensuring the fastening of the trunk 13 to the shutter plate 3 only appear on the transverse walls 33 of the trunk 13, that is to say are not very visible, and one can still to increase this effect by milling each of the walls 33 around each of the corresponding holes 38, 39 and using countersunk screws, which thus retract substantially inside the walls 33.

  Given that the threaded rods of these screws engage in the holes 29 and 30 positioned accurately, any risk of misalignment and therefore the obliquity of these screws is avoided, as well as any partial projection, for the least unsightly and sometimes dangerous, of these screws with respect to the wall 33, towards the outside of the enclosure 19.

  These screws, however, remain easily accessible for the operations of mounting and dismounting of the box 13 vis-à-vis the shutter plate 3.

  When the latch 1 according to the invention is intended to be installed in first pose on an opening, one can freely choose the diameter DI of the outer peripheral face 23 of its barrel 22, and drill the opening to the corresponding diameter to allow the passage of this barrel 22, and it is possible to realize each of the holes 27, 28 for receiving a fastening screw of the shutter plate 3, flat, against the opening, in the form of a hole with a circular contour , adapted to that of the selected screw shaft, for example of a value of 5 mm increased by a few tenths of a millimeter to receive a rod with a diameter of 5 mm, by placing the holes 27 and 28 in any relative position chosen, for example symmetrical with respect to the two planes 9 and 10, in a manner not illustrated but easily understandable by a person skilled in the art.

  However, when the lock 1 according to the invention is intended to replace a conventional latch 40 retained on the opening by screwing along two upper axes 41 and two lower axes 42 defined by holes arranged at the four corners of a front wall , similar to the wall 31, the trunk of this conventional lock, and having a barrel 43 similar to the barrel 22 and passing through it, along an axis 44 parallel to the axes 41 and 42, opening it by a hole specially designed for this purpose in this, the diameter D1 of the outer peripheral face 23 of the barrel 22 is chosen so that it is equal to the smallest of the values of the corresponding diameter D1 of a similar outer peripheral face 45, cylindrical of revolution around the axis 44, the barrel 43, at least for a given range of latches 40 known to which it is desired to substitute a lock 1 according to the invention, and it takes advantage of the fact that the holes 27 and 28 of e fixation to the shutter plate 3 are hidden by the trunk 13 after attachment thereof to the shutter plate 3, to form these holes 27 and 28 in such a way that one can engage screws fixing the shutter plate 3 to the opening by reusing the holes of respective axis 41 or 42, previously used to fix the known lock 40, as it enters the determined range in question.

  This results in giving the holes 27 and 28 respective non-circular contours, ie for example oblongs perpendicular to the planes 10 and 29, mutually symmetrical with respect to the plane 9 but mutually dissymmetrical with respect to the plane 10 as compared to the plane 29 when one chooses, as is the case in the illustrated example, to make the lock 1 according to the invention compatible with the replacement, without new drilling, of any lock 40 of any one of known types AAP whose dimensional characteristics are repeated, as well as those of the shutter plate 3 of a lock 1 according to the invention, in the table below, in which there are also dimensional characteristics, detailed subsequently, known locks 49 respectively associated and those of the base plate 4 of the keeper 2 associated with the lock 1.

  The dimensions in this table are given in millimeters, and the abbreviation VAR therein for some dimensions of the shutter plate 3 of a lock 1 according to the invention means that these dimensions vary according to the type of lock. 1 and latch 49 conventional replaced among the AAP types, given the reuse of the fixing holes thereof to receive the fastening screws of the shutter plate 3 of the lock 1 according to the invention and, in most cases, and the base plate 4 of the associated strike 2.

  With reference to FIGS. 4 and 5, the following is designated by: H1 the distance separating from the longitudinal plane 29 including the axis 24 of the barrel 22 the upper edge 7 of the shutter plate 3 of a lock 1 according to the invention , or the longest distance separating from a longitudinal plane 46 including the axis 44 of the barrel 43 of a known lock 40 an upper edge 47, flat and parallel to the. plane 46 or slightly convex upwards, the trunk of this known latch 40, - H2 the distance between the plane 29 the lower edge 8 of the shutter plate 3 of the lock 1 according to the invention, or the maximum distance separating the plane 46 a lower edge 48 of the trunk of the same known latch 40, - H3 MAX and H3 min the maximum and minimum distances separating from the plane 29 the fixing screw shafts of the shutter plate on an opening, respectively by one or the other of the holes 27, and by H3 the distance separating from the plane 46 the axes 41 of the fastening screws of the same known lock 40 located between this plane 46 and the upper edge 47, the range of possible values for H3 determining H3 MAX and H3 min, which constitute the limits, H4 MAX and HI min the maximum and minimum distances, separating from the plane 29 the screw shafts engaged respectively in the lower holes 28 to ensure the fixing of the shutter plate 3 on an opening, and by H4 the distance separates from the plane 46 the axes 42 of the screws closest to the lower edge 48 in the case of the same latch 40 known, the range of possible values for H4 determining H4 MAX and H4 min, - Ll the distance between the plane 9 one or the other of the edges 6 of the shutter plate 3 of the lock 1 according to the invention or the distance separating each of the two generally vertical edges 50, of the trunk of the same lock 40 of a transverse, vertical plane 51 including the axis 44 and constituting a mutual plane of symmetry between these two edges 50, L2 the distance separating from this plane 51 the axes 41, 42 in the case of the same latch 40 known, and respectively by L2 MAX and L2 min the distances the maximum and minimum distance between the plane 9 and the axes of the screws used to fasten the shutter plate 3 of the lock 1 according to the invention to an opening, through the holes 27 and 28, as they are defined by the maximum and minimum limits of L2, - D1 the diameter of the outer peripheral face 23 of the anon 22 of the lock 1 according to the invention, or the outer peripheral face 45 of the barrel 43 of the same lock 40 known, and - D2 the diameter of the screw rods used for fixing the same known lock 40 to an opening, according to the one or the other of the axes 41 and 42, or the shutter plate 3 of the lock 1 according to the invention to the same opening, along one or the other of the axes 41 and 42, through the holes 27 and 28 respectively, or for the attachment of a known keeper 49 or the base plate 4 of the striker 2 according to the invention to a frame.

  In this table, it has been omitted to include a distance h2, variable according to the latches 40 known, zero in some cases and sometimes corresponding to an offset offset from the offset of the plane 10 relative to the plane 29 in the case of the lock 1 according to the invention, which optionally separates from the plane 46 a plane 65 parallel to this plane 46 and passing through the axis 66 of a rotor 67 of the barrel 43. This distance h2 is indeed indifferent to the present invention.

These circles have also been shown in FIG. 6, inside the contour of each of the holes 27 and 28, and it will be observed that these have been traced by taking into account a functional game whose value has been increased. diameter D2; in terms of diameter, this functional clearance can be without disadvantage limited to 1 mm, which allows a clearance of up to 0.5 mm between each screw and the contour of the hole 27, 28 corresponding and a similar maximum possibility of deflection of the shutter plate 3, that is to say the entire lock 1 according to the invention, by pivoting about the axis 24 of the barrel 22 relative to the opening.

  As shown in particular in Figure 6, the difference in shape between the upper holes and the lower holes 28 is clearly visible and allows a poser, including professional, to easily differentiate between these upper holes and these lower holes to orient appropriately the shutter plate 3 to the installation of a lock 1 according to the invention on an opening.

  However, this orientation can be facilitated, in particular by an amateur, by providing an appropriate marking 68 of the face 5 of the closure plate 3, for example by writing the word HIGH between the two upper holes 27 and the word BAS between the two two lower holes 28, as illustrated in Figures 4 and 7 to 22.

  The contours of the fastening screws of the shutter plate 3 of the lock 1 according to the invention in the holes 27 and 28 respectively corresponding to each of the determined types AAP listed in the table are illustrated respectively in FIGS. 7 to 22, where it is noted that, in each case, the axis 24 and the planes 9 and 29 of the lock 1 according to the invention merge respectively with the axis 44 and with the planes 51 and 46 of the known lock 40 replaced.

  Like the shutter plate 3 of the latch 1, the base plate 4 of the latch 2 according to the invention is designed to group all the technical functions assigned to a latch 49 known, namely a function of receiving the latch in the position closure and a function of fixing the striker to the frame.

  For this purpose, the plate 4, considered in the position it occupies when the opening is in the closed position relative to the frame, as illustrated in the figures, has two main planar faces, one of which is not visible. FIGS, is contiguous flat to the frame, in the coplanar extension of the main face of the shutter plate 3 which is contiguous to the opening, and the other 69 extends coplanarly the face 5 of the shutter plate 3. These two main faces such as 69 have a respective rectangular shape with rounded corners, elongate in a vertical direction, and are interconnected by two transverse edges 55, 56, vertical and mutually symmetrical with respect to the transverse, vertical plane 52, and only by an upper edge 61 and a lower edge 62 longitudinal, mutually parallel and mutually symmetrical with respect to a longitudinal p = _an which merges with the plane 10 when the g che 2 is associated to the latch 1.

  Along its edge 56, turned towards the latch 1, the base plate 2 bears integrally, for example by producing, in the form of a single piece stamped from the same metal blank, a transverse flat flange 70 forming a projection at right angles to the face 69.

  When seen in the longitudinal direction 12, this flange 70 has a rectangular shape, a long side of which is defined by its connection to the base plate 4, and whose large opposite side connects to the two short sides, mutually symmetrical with respect to the plane 10, by cut edges, approximately reproducing the transverse profile of each of the flanges 11.

  In addition, in the direction 12, the rim 57 is traversed by a passage or light 71, of closed rectangular contour, for the bolt 14 when it occupies its closed position. This passage 58 is oriented like the passages 14, its largest dimension being perpendicular to the plane 10, with respect to which it is symmetrical, but it has dimensions slightly greater than those of these passages 14, in particular perpendicular to the plane 10, to allow a functional clearance vis-àvis the transverse contour of the bolt 15 when engaged in this passage 71, as is the case of a corresponding passage arranged in a striker 49 of the prior art, taking into account in particular the possibilities shifting, over time, between an opening and the associated frame.

  Respectively above and below the passage 71, the flange 70 is pierced right through, along a respective non-referenced longitudinal axis, a hole 72, 73 which can be threaded or taped by means of a self-locking screw. fastening tapping integral but removable, on the base plate 4, the cover 74 which is then devoid of any function in the retention of the bolt 15 in the closed position, while it is such a cover which constitutes the striker 49 itself in the prior art.

  The cover 74 resumes a shape similar to that of the trunk 13, and in particular comprises a front wall 75 which is connected upwardly and downwardly to two longitudinal lateral walls 76 which, with this front wall 75, define a transverse profile. identical to that the walls 36 of the trunk 13 define with the front wall 31 thereof.

  The walls 75 and 76, however, have a longitudinal dimension smaller than that of the walls 31 and 36, as is also the case of the base plate 4 compared to the closure plate 3, and are connected respectively in one and the other direction of the longitudinal direction 12, to a transverse side wall 77, 78, the first of which, facing the latch 1 when the striker 2 cooperates with it, is full whereas the second, then turned towards the bolt 1, has a shape identical to that of one or the other of the transverse walls 33 of the trunk 1, that is to say presents as these a passage 79, identical to the passages 34, for the bolt 15. As each passage 34, this passage 79 is devoid of any function of guiding or retaining the bolt 15, and it has a transverse contour of dimensions greater than those of the passage 71, which it wraps when the cover 74 is assembled to the base plate 4, in a position in which side walls 76, 77, 78 surround it by more or less closely matching its edges 61, 62, 55, 56, the wall 78 being flat against the flange 70 opposite the base plate 4 in relation to this one. The free edges 80, 81, 82, mutually coplanar, that the walls 76, 77, 78 have opposite their connection to the wall 75 are coplanar with the main face by which the base plate 4 is contiguous to the frame .

  Then, facing each of the passages 72, 73 of the flange 70, the wall 78 of the cover 74 has, coaxially, a respective hole 83, 84 for receiving a removable fastening screw of the cover 74 to the flange 70, that is ie to the base plate 61, by screwing into the passage 72, 73 associated. Advantageously, each of the holes 83, 84 is milled so as to drown the head, also milled, of the corresponding screw.

  When the keeper 2 according to the invention is intended for a first mounting on a frame, it may have, for the reception of fastening screws therein, two upper holes 53 and two lower holes 54 of circular contour respectively and located by example at the four corners of the main face 69, symmetrically with respect to a transverse plane 52 of symmetry between the edges 55 and 56 as compared to the plane 10.

  When, on the other hand, the striker according to the invention 2 is intended, like the lock according to the invention 1, to replace, without requiring additional drilling, a traditional striker 49, associated with a traditional latch 40, the holes 53, 54 may present, in a manner not illustrated but easily by a person skilled in the art in view of above, the manner in which holes 27 and 28 for receiving the screws are sealed, the shutter plate 3 for reusing the screw holes of fixing the known striker 49 to the frame to fix thereto the base plate 4 of the striker 2 according to the invention, or, preferably and as illustrated, an outline adapted to allow reuse these holes only in the extent to which they are not too close to the rebate of the frame and compatible with drilling new fastening screw receiving holes sufficiently far away from the pre-existing holes so as not to weaken the fastening, it being understood that a group for m by two holes 53, 54 located on the same side of the plane 52 can receive screws associated with existing holes of the frame whereas the screws associated with a group formed by the two holes 53, 54 located on the other side plan 52 may require a new drilling of the frame.

  understandable description, outline of

  It is also preferable to provide that the outline of the holes 53 and 54 is compatible with a positioning of the striker 2, indifferently, on both sides. lock 1 to allow to use the same lock 1 for a left opening and a right opening, according to the conventional name.

  To these two effects, in the illustrated example, the holes 53 and 54 have identical contours, ie rectangular with rounded corners, the largest dimension of which is oriented perpendicularly to the plane 10 with respect to which, moreover, the holes 54 are symmetrical holes 53.

  The outline of each of them is defined by a rectangular envelope, with rounded angles and a functional clearance near the order of 1 mm in diameter, at most, of all circles of diameter D2, centered on the any of the positions that can occupy, in a known striker 49 associated with a latch 40 of one or other of the types A to p, the axes 59 of two screw holes, to the frame, located above the plane 46, assumed common to the striker 49 of the prior art and the latch 40 known to which it is associated, that is to say to each of the connecting corners of a longitudinal upper edge 63 of the striker 49 to a respective transverse edge 58 thereof, and the shafts 60 of two screw holes to the frame located below this plane 46, at each of the connecting corners of a longitudinal lower edge 64 of the striker 49 at a respective transverse edge 58 of the latter, provided, however, that the axes 59, 60 of the two most hes of the rabbet, not shown, the frame is not less than a limit value which has been chosen equal to 10 mm, by way of non-limiting example, for the sake of safety of the attachment of the striker 2 to against a break-up.

  With reference to FIGS. 4 and 5, in the table above, the following dimensions have been designated respectively by: H5 and H6, measured in a similar manner to the distances H1 and H2 but either between the plane 29 and the edges respectively greater than 61 and lower 62 of the base plate 4 of the striker 2 according to the invention, or between the plane 46 and the edges respectively upper 63 and lower 64 of a known striker 49, associated with the same latch 40, H7, H8, H7 MAX, H7 min, H8 MAX and H8 min the distances, respectively measured on the same known striker 49, from the plane 46, and on the base plate 4 of the keeper 2 according to the invention, from the plane 29, as are respectively the distances H3, H4, H3 MAX, H3 min, H4 MAX and H4 min on the same known latch 40 and on the shutter plate 3 of the latch 1 according to the invention, L3 the distance separating from the transversal plane 52 symmetry between the two groups of two holes 53, 54 arranged in the base plate 3 both transverse edges 55, 56 thereof, or the distance separating a transverse plane 57 of symmetry between the pins 59, 60 for screwing the same known striker 49 to a frame, respectively above and below the plane 46 , each of two transverse edges 58 of this known striker 49, mutually symmetrical with respect to this plane 57, L4 the distance separating from the plane 57 the pins 59, 60 of the fixing holes of the same known striker 49 to a frame, located respectively above and below the plane 46, while L4 MAX and L4 min denote the maximum and minimum distances respectively between the plane 52 and the screw axes engaged respectively in the holes 53 and 54, in a position identical or not to that a screw for fixing the known striker 49, that is to say along the same axis 59 or 60 or not, to ensure the attachment of the base plate 3 of the striker 2 according to the invention to a frame , these distances L4 MAX and L4 min being determined, on the one hand by the limit values of L4 and secondly by the abovementioned concern of resistance to tearing and selected, in this non-limiting example, respectively of a value of 9.5 mm and a value of 7.5 mm .

  It will be observed that, while the positions of the axes 59 and 60 are defined, with regard to each known striker 49, with respect to the longitudinal plane 46 common to the latch 40, as well as with respect to the transverse plane of symmetry 57 of this striker 49 known, these positions are defined, with respect to the base plate 3 of the keeper 2 according to the invention, to determine the contour and the position of each hole 53, 54, with reference to the plane 52, on the one hand, and both in reference to the plane 29 and in reference to a longitudinal plane 85 parallel to the plane 29 and symmetrical thereof relative to the plane 10, that is to say situated at the same distance h] of the plane 10 29. This has been translated, in FIG. 4, by the recovery of the same dimensions H7 MAX and H7 min respectively above the plane 29 and below the plane 85 and, correspondingly, by the recovery of the same dimensions. H8 MAX and H8 min respectively below the plane 29 and above the plane 85, to defeat Inir the respective limits of position of the centers of the circles defining the outlines of the holes 53 and 54 in the direction of a distance and in the direction of a rapprochement with respect to the plane 10.

  It can be shown that by adopting the values of H7 MAX, H7 min, H8 MAX, H8 min and L3 appearing in the table and the aforementioned values of L4 MAX and L4 min, and taking into account the diameter of the heads of the screws whose stem presents the diameter D2, for example equal to 5 mm in the case of the fixing of a baseplate 3 keeper 2 according to the invention as in the case of a striker 49 of the prior art, associated with one Any of the types A to P of known locks 40, by aligning the plane 29 of the base plate 4 of the striker 3 according to the invention with the plane 46 of the known striker 49, as illustrated. FIGS. 7 to 22, and reusing as far as possible the holes used for fixing such a known striker 49 to fix the base plate 4 of the striker 3 according to the invention, and / or by piercing in the frame of new holes possibly necessary, keep a support of each screw head on the face 69 to the edge of the hole 53 or 54 r correspondingly corresponding, and limit the clearance between each screw rod and the contour of the hole respectively corresponding to allowable tolerances in terms of accuracy of the positioning of the striker 2 on the frame, in relation to the position of the lock 1 on the opening.

  Alternatively, each of the holes 53, 54 could be replaced by a group of two holes mutually juxtaposed in a direction perpendicular to the plane 10, maintaining the same symmetries between groups of holes on the one hand relative to the plane 10 and other part relative to the plane 52, to increase the support between each fixing screw of the base plate 3 to the frame and the contour of the respectively associated hole, although this did not appear essential during testing, or present a respective complex contour, designed as described with respect to the holes 27 and 28 of the shutter plate 3 of the latch 1, to allow the reuse of all the holes previously arranged in the frame to receive the fastening screws d A conventional striker of any of the types A to P. In general, the embodiments which have just been described for the lock 1 according to the invention and the striker 2 according to the invention do not constitute Non-limiting examples, with respect to which we can provide many variants, in particular with regard to the conformation and the position of the different holes 27, 28, 53, 54 respectively fixing the shutter plate 3 to 1. opening and the base plate 4 to the frame, according to other specific types of locks and strikes to which it will be desired to be able to substitute without new drilling a lock 1 according to the invention and by limiting the new holes, to the extent possible, a keeper 2 according to the invention. Similarly, the mounting mode of the various components of the latch on the shutter plate 3 will be different from the mounting mode described, since this shutter plate 3 will serve as an intermediate assembly of these components on the opening, and the practical configuration of the base plate 4 of the striker 2 may also be modified without departing from the scope of the present invention, since this base plate 4 will serve as a fixing intermediate, to the frame of the hood 74 of the striker 2.
