EP 1 598 508 of Lock Industry DOMUS Security S.A. discloses a multipoint latching assembly for sliding panels comprising a pair of cooperatively employed longitudinally extending abutting bars, such bars being provided within a vertically extending frame end portion of the sliding profile member, wherein the first bar is fixedly mounted at a plurality of points of the sliding profile member and the other bar is provided with a plurality of latch means and performs a reciprocating movement thereby accordingly setting the multipoint latching assembly at a locked or unlocked condition. When the locking assembly is set at locked condition, the plurality of latch means of the reciprocatingly moving bar protruding outwardly of the sliding profile member engage with a corresponding plurality of suitably formed latch receiving members, which are mounted at functionally appropriate positions at the frame profile member located opposite to the plurality of latch means. The two cooperatively abutting bars are oblong with a width such as to allow them to pass freely through the opening at the vertically extending frame end portion of the sliding door or window located opposite to the frame profile member and have a length such as to cover a desirable portion up to the entire length of the vertically extending frame end portion. The first bar is fixedly mounted at a plurality of points by means of an arrangement of supporting blocks and bolts that pass through the supporting blocks and through both bars, such bolts being screwed until the bars abut onto an inner traverse wall of the sliding panel profile member and a pair of side flanges of the supporting blocks abut onto frontal side walls of the sliding panel profile member thereby providing counter support. The plurality of latch means of the second bar are adapted to pass through an equivalent plurality of channels of the first abovementioned bar, whereby the reciprocating movement of the second bar displaces the latch means along the channels of the first bar and allows them to engage with an equivalent number of latch receiving members provided along the oppositely facing vertically extending frame profile member thereby locking the panel at a plurality of points equivalent with the corresponding plurality of latch means and receiving members being employed.
In order to overcome the possibility of deformation or even breaking of the latch means and/or of the receiving members due to inappropriate operation of closure of the sliding panel whilst the latch means are found at a locked condition whereby the latch means collide onto the receiving members, probably violently, EP 1 598 508 proposed the connection of the two cooperatively abutting bars with an arrangement of automatic retraction and return means, such automatic retraction and return means comprising a plurality of pins provided with springs, such pins extending marginally forwardly the latch means so as to constitute the first points of contact in any involuntary collision whatsoever, thereby allowing, through the springs, the retraction of the second bar that is provided with the latch means with a scope of effectively protecting the latch meanss and the receiving members accordingly and thus safeguarding the overall locking assembly. The object of the present invention is to provide a multipoint locking assembly for sliding doors and windows comprising a single reciprocatingly moving bar provided with a plurality of latch means installed within a vertically extending frame end portion of the sliding profile member and a bar with an equivalent plurality of latch receiving members fixedly mounted onto the vertically extending length of the frame profile member located opposite to the above mentioned vertically extending frame end portion of the sliding profile member, such multipoint locking assembly constituting a simplification and optimisation of multiple point locking in sliding panels.
A first element of the simplification achieved is that instead of the pair of parallel cooperatively abutting bars of EP 1 598 508, which are installed within the vertically extending frame end portion of the sliding profile member with the first of these bars being fixedly mounted onto the sliding frame profile and the second moving reciprocatingly during locking/unlocking operation of the lock assembly, a single bar is installed within the vertically extending frame end portion of the sliding profile member, such bar having a specific characteristic configuration of a pair of side flanges provided at a plane different from the plane of the general length of the bar, such side flanges being shaped so as to form basements of a pair of supporting blocks by means of which the single bar is mounted onto the frontal inner walls of the sliding frame profile member, such basements being provided with longitudinal channels for the passage of connecting bolts, such longitudinal channels allowing said bar to execute freely its reciprocating movement during locking/unlocking operation of the multipoint locking assembly, wherein this single bar with the characteristic configuration of the present invention consequently combines both functions, i.e. on the one hand the function of fixedly mounting onto the sliding frame profile member through the abovementioned supporting blocks and on the other hand the function of executing a reciprocating movement during the process of locking/unlocking operation of the lock assembly.
Thus the object of the present invention is the disclosure of the abovementioned bar of characteristic configuration arranged vertically along within the sliding frame profile member and fixedly mounted thereupon by means of the abovementioned supporting blocks being connected at the two side flanges thereof in a manner such that the bar through the supporting blocks bears against the frontal inner walls on either side of the frontal opening of the sliding frame profile member, whilst through the connecting bolts of the supporting blocks it also bears against an interior transverse wall of the sliding frame profile member that separates the frontal chamber of the sliding profile member wherein the bar is installed from the central chamber of the sliding profile member wherein the locking activation mechanism is installed.
A second element of the simplification achieved is that instead of the utilisation of two distinct arrangements a) of means for mounting the bar onto the internal walls of the sliding profile member implemented by means of the abovementioned supporting blocks, and b) of means for the automatic retraction of the bar for averting possible damage either of the latch means and/or of the receiving members thereof in case of an involuntary collision of the sliding profile member onto the frame profile member with the latch means being positioned at locked condition, a single arrangement of spring carrying supporting blocks is employed for simultaneously accomplishing both the abovementioned functions of bar mounting and automatic bar retraction and return movement in case of a threatened involuntary collision of the latch means onto the receiving members.
An object of the present invention is further to suggest improvements in the proposed spring carrying supporting block rendering the same suitable for a number of different series of profiles for sliding panels that present small differences of dimensions and configuration and in particular small differences in the width dimension thereof, wherein this suitability of the same supporting block for a variety of different series of profiles for sliding panels is obtained with the curving of the exterior sides of the pair of legs of the supporting block, so as to facilitate the insertion of the supporting block through the frontal opening of the sliding profile member, the same being consequently brought to the operational position of bearing against the internal frontal walls of the sliding profile member through execution of a rotation of a variable arc with respect to the latch means carrier bar. It should herein further be noted that the supporting block of the present invention is further differentiated from the supporting blocks as disclosed in EP 1 598 508 in that a seat for the reception of the spring providing the retracting capacity is formed within the central aperture of the block wherein is inserted the connection bolt for connecting the same to the bar.
Another object of the invention is to suggest alternative combinations of latch means and latch receiving members of the proposed multipoint locking assembly, wherein it is either the reciprocatingly moving bar installed within the sliding profile member that is provided with a plurality of latch means whereby the bar mounted onto the frame profile member is provided with an equivalent number of latch receiving means or it is the bar mounted onto the frame profile member that is provided with the plurality of latch means and accordingly the reciprocatingly moving bar that is installed within the sliding profile member is provided with an equivalent number of latch receiving means, and wherein the latch means can alternatively take the form of locking tongues, pins, hooks or other locking elements whatsoever, whereby the latch receiving means take a correspondingly suitable form for effecting locking engagement with the latch means. Another object of the invention is to disclose improvements relating to the locking elements being employed, proposing in particular an adjustable locking pin and more specifically a locking pin the length of which can be adjusted, so that after installation of the locking assembly, regulation may be effected of the length of the locking pin, thereby obtaining an optimally functional result in the locking capacity of the proposed multipoint locking assembly.
These and other objects and advantages of the present invention will become apparent in the detailed description following hereinafter.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS We will hereinafter describe illustrative preferred embodiments of the invention by reference to the accompanying drawings.
The multipoint locking assembly proposed in the present invention is applicable to sliding doors or windows, which comprise a sliding profile member 15 with a frontal opening 15c and a frame profile member 16 of the type depicted in Fig. 1 or in Fig. 2. As shown in Fig. 1 and Fig. 2 respectively, the frame profile member 16 comprises a protruding member 16a or 16a', that is being introduced through the frontal opening 15c within a frontal chamber of the sliding profile member 15 when the door or window is slided to closure position.
The sliding profile member 15 comprises a pair of parallel surfaces, which are bent inwardly at the extremities thereof to form walls 15a on either side of the frontal opening 15c and are being interconnected by means of a pair of transverse parallel surfaces 15b, 15d, a chamber of installation of a locking activation mechanism 25 being provided in between these transverse surfaces 15b, 15d.
The locking activation mechanism 25 that is mounted inside the chamber defined by the transverse surfaces 15b, 15d may be operated by means of various types of handle means of the locking assembly, such as the rotatable locking operation handle means 24b illustratively shown in Fig. 1 that is provided with a covering plug means 24a mounted onto the surface of the sliding profile member 15. A reciprocatingly movable locking operation handle means may also be employed. As alternatively shown in Fig. 5, a pair of symmetrically opposite apertures 29a are provided onto the parallel surfaces of a vertically extending portion of the sliding profile member 15 at the region of installation of the multipoint locking assembly and the locking operation handle means 24b is installed onto one interior surface of the pair of parallel surfaces of the sliding profile member 15, whilst a handle means 24b' that is unable of effecting a locking operation is installed onto one exterior surface of the pair of parallel surfaces of the sliding profile member 15 symmetrically opposite the locking operation handle means 24b. The locking operation handle means 24b extends into a shaft 29 that sequentially passes through an interior aperture 29a of the pair of apertures 29a, through an aperture 28a of a planar side extension of the planar section 26 of the locking activation mechanism 25, through the other exterior aperture 29a of the pair of apertures 29a and is finally fixedly mounted within an aperture 29b of the handle means 24b'.
A first bar 1 with a plurality of locking engagement means 7, 7a is provided within the frontal chamber of the sliding profile member 15, wherein this first bar 1 is connected to the locking activation means 25 by means of a a bolt 5. The locking activation mechanism 25 that is mounted within the chamber provided in between transverse surfaces 15b, 15d of the sliding profile member 15 comprises a planar section 26 with a pair of internally threaded apertures 26a, wherein one end of the connecting bolt 5 is screwed into one of the above pair of internally threaded apertures 26a of the planar section 26 of the locking activation mechanism 25 and the other end of bolt 5 protrudes perpendicularly outwardly surface 15b of the chamber provided in between transverse surfaces 15b, 15d and is subsequently screwed into an internally threaded aperture 5a of the abovementioned first bar 1. Rotation of the locking operation handle means 24b results in a reciprocating movement of the planar section 26 of the locking activation mechanism 25 and accordingly of the first abovementioned bar 1 thereby effecting engagement or disengagement of the plurality of locking engagement means 7, 7a thereof with an equivalent plurality of locking engagement means 6, 6a of a second bar 1 1 that is fixedly mounted onto the abovementioned protruding member 16a or 16a' of the frame profile member 16. The second bar 1 1 with the equivalent plurality of locking engagement means 6, 6a is provided with an arrangement of apertures 14a through which pass screws 14 for fixedly mounting the same onto the protruding member 16a or 16a' of the frame profile member 16.
As the locking operation handle means 24b is turned to selectively set the multipoint locking assembly at a locked or unlocked condition, the locking activation mechanism 25 transmits the rotation of the locking operation handle means 24b to the first bar 1 that is led to perform a reciprocating movement initiated by the locking activation mechanism 25 thereby effecting engagement or disengagement respectively of the plurality of locking engagement means 7, 7a thereof with the equivalent plurality of locking engagement means 6, 6a of the second bar 11. The abovementioned first bar 1 is a longitudinally extending section with nerved longitudinal edges and with a pair of identical inclined portions 1 ' at the two extremities thereof, wherein the inclined portions 1 ' extend into a pair of identical side flanges Ia which are provided at a plane different from the plane of the general length of bar 1. Each one of the side flanges Ia is provided with a centrally oriented longitudinal channel 4a and is adapted to form basements of a pair of supporting blocks 23. The length of channel 4a allows for the locking or unlocking stroke of the multipoint locking assembly.
As shown in Fig. 4 each one of the supporting blocks 23 is a Fl-section with a base portion 20c forming an exterior basement surface 23c seated onto the side flange Ia, wherein a through aperture 23b is provided centrally through base portion 20c and bolts 4 with an extended planar head 4' and a centrally located sharp edge 19, as illustratively shown in Fig. 4a, are driven through the apertures 23b of the supporting blocks 23 and through the longitudinal channels 4a of the side flanges 1 a of the first abovementioned bar 1 until the sharp edges 19 of bolts 4 are embedded into the transverse surface 15b of the sliding profile member 15. Springs 3 are provided around the body of bolts 4, wherein these springs 3 are confined in between the extended planar heads 4' of bolts 4 and the exterior basement surfaces 23c of supporting blocks 23. These springs 3 are adapted to effect an automatic retraction of first bar 1 when a pressure is exerted thereupon, if one attempts to close the door or window whilst the locking engagement means of the first bar 1 are at a locked position and threfore collide onto the locking engagement means of the second bar 1 1. The resulting automatic retraction is effected at a distance equivalent with the compression stroke of springs 3, whilst an automatic return of first bar 1 is effected immediately thereafter with the subsequent expansion stroke of springs 3. The planar end surfaces 23a of a pair of side legs 20a, 20b of the supporting blocks 23, which are perpendicularly oriented with respect to the base portion 20c of the supporting blocks 23, abut onto the abovementioned inwardly bent frontal walls 15a on either side of the frontal opening 15c of the sliding profile member, thereby providing counter support of the first bar 1 within the sliding profile member. The supporting blocks 23 have a width equivalent to the width of first bar 1 to allow introduction of the same within the sliding profile member 15 whilst they are oriented linearly along first bar 1 and they have the exterior surfaces 2a, 2b of the side legs 20a, 20b respectively formed in the shape of identical curved sectors of a circle so as to allow rotation of supporting blocks 23 following introduction thereof within the sliding profile member 15 at a variable angle of rotation for sliding profile members of different width, such rotation aiming at bringing the supporting blocks 23 in a direction substantially transverse to the direction of first bar 1 thereby allowing the planar end surfaces 23a of the pair of side legs 20a, 20b to bear against the inwardly bent walls 15a on either side of the frontal opening 15c of the sliding profile member 15.
As illustratively shown in Fig. 1 the protruding member of the frame profile member 16 that is being introduced through the frontal opening 15c within a frontal chamber of the sliding profile member 15 when the door or window is slided to closure position is a closed Fl-section member 16a, and the second bar 11 is a planar section screwed onto a frontal surface of this closed Il-section member 16a by means of screws 14 that pass through the arrangement of apertures 14a of second bar 11.
Alternatively, as illustratively shown in Fig. 2, the protruding member of the frame profile member 16 is is an open Fl-section member 16a', and second bar 11 also preferably is an open Fl section. In this case connection elements 10 with a butterfly configuration are employed in the connection of second bar 11 onto the open Fl-section protruding member 16a' (Figs. 3a, 3b).
As shown in Figs. 3e and 3c, each one of the connection elements 10 comprises a basement 10'. An internally threaded tubular member 17 with an open end 17a extends on one side of basement 10' and a closed tubular member 18 extends on the other side of basement 10'. Basement 10' has a curvilinear perimeter with a larger side exceeding the diameter of the tubular member 17 and a smaller side not exceeding the diameter of the tubular member 17, whereby the connection element 10 is introduced within the open Fl- section member 16a' through the smaller side of basement 10' and is retained within the same through subsequent rotation thereof by 90° to effect contact of the larger side thereof with the walls of the open Il-section member 16a'. At this position screws 14 pass through the arrangement of apertures 14a of second bar 11 and are screwed within the internally threaded tubular member 17 of connection element 10 for fixedly mounting second bar 11 onto the open Fl-section protruding member 16a'.
In accordance with a first preferred embodiment of the invention illustratively shown in Fig. 1 , the abovementioned plurality of locking engagement means 6, 6a of the second bar 11 is latch means that can alternatively take the form of locking tongues, pins, hooks or other locking elements whatsoever and the equivalent plurality of locking engagement means 7, 7a of first bar 1 thereby is an equivalent plurality of latch means receiving channels 7a. Each one of the plurality of channels 7a has a length such as to allow the latch means to move within the same during a linear locking or unlocking stroke thereof, where each channel 7a is divided in two portions, one portion having a smaller width along one half of the length thereof and another portion having a larger width along the other half of the length thereof. The latch means when set at an unlocked condition are being inserted within channels 7a through the portion of larger width thereof, whilst after completion of a locking stroke the latch means move into the portion of smaller width of channels 7a wherein they are engaged thereby effecting a locked condition of the multipoint locking assembly.
In accordance with a second preferred embodiment of the invention illustratively shown in Fig. 2, the abovementioned plurality of locking engagement means 7, 7a of first bar 1 is latch means that can alternatively take the form of locking tongues, pins, hooks or other locking elements whatsoever and the equivalent plurality of locking engagement means 6, 6a of the second bar 11 is an equivalent plurality of latch means receiving channels 6a, each one of the plurality of channels 6a having a length such as to allow the latch means to move within the same during a linear locking or unlocking stroke thereof and each one of the plurality of channels 6a being divided in two portions, one portion having a smaller width along one half of the length thereof and another portion having a larger width along the other half of the length thereof, whereby the latch means when set at an unlocked condition are inserted within channels 6a through the portion of larger width thereof, whilst after completion of a locking stroke the latch means move into the portion of smaller width of channels 6a wherein they are engaged thereby effecting a locked condition of the multipoint locking assembly.
As illustratively shown in Fig. 2e the latch means 7 provided onto the abovementioned first bar 1 or alternatively accordingly the latch means 6 provided onto the second bar 11 is a locking tongue comprising a rectilinear body portion 27a welded onto the surface of the first bar 1 or second bar 11, where the rectilinear body portion 27a extends into a rectangular head portion 27b that has dimensions larger than those of the rectilinear body portion 27a, whereby the rectangular head portion 27b is capable of passing through the portion of larger width of channels 6a or 7a of the second bar 11 and of the first bar 1 respectively, whilst it is unable to pass through the portion of smaller width of channels 6a or 7a of the second bar 11 and of the first bar 1 respectively wherein it is engaged when the multipoint locking assembly is set at locked condition.
Alternatively as illustratively shown in Fig. 1 f, the latch means 6 provided onto the abovementioned second bar 11 or alternatively accordingly the latch means 7 provided onto the first bar 1 is a locking pin with a mushroom configuration. This locking pin comprises a cylindrical body portion with an upper extended mushroom head portion 7' (or 6' of the first bar 1) and a lower portion 7" (or 6"), where the lower portion 7" (or 6") is welded onto the surface of the second bar 11 or first bar 1 and the upper extended mushroom head portion T (or 6') has dimensions such as to be capable of passing through the portion of larger width of channels 7a of the first bar 1 (or 6a of the second bar 11), whilst being unable to pass through the portion of smaller width of channels 7a (or 6a), wherein it is engaged when the multipoint locking assembly is set at locked condition.
Furthermore as illustratively depicted in Fig. Ig, the latch means 6 provided onto the abovementioned second bar 11 or alternatively accordingly the latch means 7 provided onto the first bar 1 is a locking pin with a mushroom configuration and an adjustable length. This locking pin comprises three portions and in particular: a first pin portion 6 (or 7) with an externally threaded cylindrical body 6b (or 7b) that extends into an extended mushroom head portion 6' (or T) and a central aperture 6a (or 7a); a second pin portion 8 comprising an internally threaded tubular body with an open end 8a and an annular basement 8' with an extension 8b that is expanded during the welding process for effecting fixedly mounting of the annular basement 8' onto the second bar 1 1 (or the first bar 1). The externally threaded cylindrical body 6b (or 7b) of the first pin portion 6 (or 7) is introduced through the open end 8a and screwed into the internally threaded tubular body of the second pin portion 8. A third tubular pin portion 9 with an opening 9a and an interior with hexagonal configuration adapted to receive a rotation effecting corresponding key is introduced within the central aperture 6a (or 7a) of the first pin portion 6 (or 7), whereby the rotation effecting corresponding key being introduced through the opening 9a of the third pin portion 9 effects stabilization of the first pin portion 6 (or 7) at a desirable depth of insertion within the second pin portion 8 thereby defining the length of the pin protruding outwardly the second bar 11 (or the first bar 1) and where the upper extended mushroom head portion 6' (or 7') has dimensions such as to be capable of passing through the portion of larger width of channels 6a (or 7a) of the second bar 11 or of the first bar 1 respectively, whilst being unable to pass through the portion of smaller width of the channels 6a (or 7a) of the second bar 11 and of the first bar 1 respectively wherein it is engaged when the multipoint locking assembly is set at locked condition.
It is hereby noted that the description of the invention was made by reference to illustrative but not confining examples. Thus any modification that does not include an inventive step in itself is considered part of the scope of the invention as defined in the following claims.
