Description

The present invention relates to a handle system for a wing of a window or door and an installation method thereof.
More precisely, the invention is applied in the field of locks provided with a push-pull control, i.e. a control capable of converting the pushing or pulling movement of a handle into a rotational motion applied to the so-called handle follower, which in turn controls the translation of a closing element, typically a latch or a bolt.
A lock provided with push-pull control, already the subject matter of a previous patent document in the name of the same Applicant, has the advantage of leaving complete freedom as to the shape of the handle to be used, since the latter must only receive pushing or pulling forces and no longer rotational ones.
The present invention is applied in the field of windows and doors in general.

PRIOR ART

As is well known, the windows and doors used to close off access to the rooms of a building are fitted with locks provided with a latch and/or bolt.
According to the prior art, a first type of lock comprises a lock body suitable for being inserted into a housing of a wing of a window or door. The lock body is provided with an actuator assembly for slidingly moving a closing element, for example a latch, between a configuration in which it is retracted inside the lock body and a configuration in which it is extracted from the lock body, so that it may engage in a corresponding latch hole fashioned in one of the vertical uprights, or jambs, making up the fixed part of a window or door.
The latch is generally provided with an inclined surface suitable for abutting against and sliding over an edge of a striking plate installed on the fixed vertical upright of a window or door, said inclined surface thus bringing about the retraction of the latch into the lock body during the wing closing phase.
In accordance with the prior art, the latch is opposed by a spring which tends to maintain it in a configuration in which it is normally extracted from the box-shaped body; therefore, after coming to abut against the edge of the striking plate and being retracted into the lock body until passing the aforesaid edge of the striking plate, the latch is brought back into the extracted configuration by the spring, so that it can be inserted into the latch hole fashioned on the fixed upright of the window or door and thus bring about the closing of the window or door.
Again in accordance with the prior art, there also exist locks of a magnetic type, in which the latch is drawn into the latch hole by a magnet generally positioned on the jamb of the window or door.
In both techniques of the prior art briefly described above, in order to disengage the latch from the latch hole and enable the window or door to be opened again, it is necessary to bring about the retraction of the latch into the lock body manually. This retraction is normally achieved using a handle, which is connected to the latch by means of a series of kinematic motion and is made to rotate about an axis perpendicular to the sliding direction of the latch. In greater detail, the rotation of the handle thus determines a sliding motion of the latch towards the inside of the lock body (retracted position).
The main drawback of the prior art is represented by the fact of not allowing any freedom to choose the shape of the handle to be used, which must necessarily be capable of rotating about a rotation axis perpendicular to the sliding direction of the latch. Disadvantageously, therefore, it is not possible to allow the user any freedom of choice in respect of the type of operation, it being strictly necessary to rotate the handle in order to enable the opening of the lock, and hence of the window or door. Even more disadvantageously, this type of operation greatly limits the freedom, from a design standpoint, to create handles of any shape whatsoever.
In order to overcome the aforesaid drawbacks, the Applicant has developed a lock provided with a push-pull control capable of converting the pushing or pulling movement exerted on a handle into a rotational motion applied to the so-called handle follower which controls the sliding of the latch. Advantageously, such a lock assures greater freedom in the shape of the handle to be used, while simultaneously offering a simple and immediate operation.
In greater detail, a lock provided with push-pull control comprises a lock body and a latch movable between an extracted configuration and a configuration in which it is retracted inside the lock body. The lock is provided with a latch actuator assembly comprising an actuator member, typically a hollow body defining the so-called handle follower, which is movable by rotation between two operating positions which correspond, respectively, to the aforesaid extracted and retracted configurations of the latch. Furthermore, the actuator assembly comprises a control member kinematically connected to the actuator member in order to control the rotation thereof; in particular, the control member is movable along a direction of translation between two operating positions corresponding, respectively, to the rotated operating positions of the actuator member, which, in turn, correspond to the extracted and retracted configurations of the closing element. The control member receives the pushing or pulling action via the handle.
The control member has dimensions such as to slide inside the hollow body. Typically, the control member is a piston. The interaction between the control member (piston) and the actuator member (handle follower) takes place through a cam with a partial helical surface and integral with the control member, said cam slidingly intercepting a cam follower element integral with the actuator member; therefore, as a result of the sliding of the cam follower element inside the cam, the translation movement of the control member is converted into a rotation movement of the actuator member.
The handle is positioned and fixed onto the wing in such a way as to interact with the control member.
The push-pull locks described above, despite being very reliable, have several drawbacks.
Firstly, the pushing or pulling movement exerted on the actuator assembly by the handle causes shifts and oscillations, even if minimal, of the lock body in the direction of application of the force, thus reducing the working stroke of the control member and diminishing, therefore, the effectiveness of the actuation of the lock. At present, in fact, the lock body is inserted into a cavity fashioned on the front surface of the movable part of the window or door, typically a wing, according to a direction of insertion that is substantially parallel to the sliding direction of the closing element, for example a latch. The lock body is kept in position by means of a pair of screws that fix a front plate of the box-shaped body to the front surface of the wing. In this method of installation, therefore, the box-shaped body of the lock can be subjected to shifts or oscillations in a direction orthogonal to the direction of insertion, which typically also coincides with the direction of fastening defined by the screws. In other words, the pushing or pulling force determines a movement of the control member, but also a simultaneous movement of the lock body, so that the working stroke of the control member inside the handle follower is reduced, with a consequent decline of effectiveness in the operation of the latch.
Furthermore, in order to assure the maximum effectiveness of operation, it is necessary to align the handle relative to the control member. Disadvantageously, to date, the handle is instead installed with reference to the openings for accessing the cavity housing the lock body in the wing, it not being possible to align the handle relative to the control member.
Prior art document KR20110036425 is also known and it discloses a door lock comprising a first fixing unit, a second fixing unit, a movable member, a pressing unit, a pulling unit, a latch case, a locking bar, a door lock unit, a latch bolt, a latch-bolt moving unit, and a return spring.
Document US 5,516,163 , in accordance with its abstract, discloses a device for operating a linearly activated door latch including exterior and interior knob assemblies connected by a threaded rod. Pushing the exterior knob causes the rod to move towards the door and the cam on the rod will contact the cam follower on the receiver whose tab will rotate the lever to retract the bolt. Once the bolt is retracted and the door is open, a return spring will bias the bolt back to the extended position.
Document US 2,504,483 , in accordance with its introductory part, discloses a locking device designed particularly for use on doors with a push/pull movement of the handles.

OBJECTS OF THE INVENTION

In this context, the technical task underlying the present invention is to provide a handle system for a wing of a window or door and an installation method thereof which overcome the drawbacks of the above-mentioned prior art.
In particular, it is an object of the present invention to provide a handle system which eliminates the shifts and oscillations of the lock body during the application of a pushing or pulling force on the control member.
Another object of the present invention is to provide a handle system which can be precisely aligned with the control member.
A further object of the present invention is to provide a handle system able to assure ample freedom of installation, in such a way as to eliminate or minimise the design constraints for individual operators, that is to say, manufacturers of locks, handles or of windows and doors.
Another object of the invention is to provide an installation method that enables the handle system to be rapidly mounted on the wing of a window or door.
The stated technical task and specified objects are substantially reached by a handle system for a wing of a window or door and the installation system thereof, which comprise the technical features disclosed in the independent claims. The dependent claims correspond to further advantageous aspects of the invention.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION

With reference to the figures, a handle system according to the invention has been generically indicated with the number 1.
The other numerical references refer to technical features of the invention which, barring indications otherwise or evident structural incompatibilities, the person skilled in the art will know how to apply to all the variant embodiments described.
The handle system 1 according to the invention is applicable on a wing D of a window or door provided with a lock body 2 of the type comprising a closing element 3, typically a latch movable between a configuration in which it is extracted from the lock body (for example, figure 11) and a configuration in which it is retracted inside the lock body (for example, figure 14).
The lock body 2 comprises a control member 4 kinematically connected to the closing element 3, said control member being subjectable to a pushing or pulling force in order to translate between at least two operating positions corresponding, respectively, to the extracted and retracted configurations of the closing element 3 (figures 11 and 14).
According to one illustrated embodiment, for example, in figures 3, 11 and 18, the system 1 comprises a pair of base elements 101a, 101b, integrally associable with the wing D in opposing positions relative to the lock body 2, and a pair of grippable elements 102a, 102b suitable for exerting a pushing or pulling force on the control member 4 in order to bring about the translation thereof.
In accordance with one illustrated embodiment of the invention, for example in figures 1-8 and 8A, the handle system has a pair of grippable lever-shaped elements 102a, 102b substantially set into the wing D.
In accordance with another illustrated embodiment of the invention, for example in figures 9-17 and 17A, the handle system has a pair of grippable lever-shaped elements 102a, 102b positioned close to the wing D.
In accordance with a further illustrated embodiment of the invention, for example in figures 18 and 19, the handle system has a pair of grippable knob-shaped elements 102 projecting relative to the wing D.
According to one embodiment of the invention, the system 1 comprises a spacer means 103 integrally associable with the base elements 101a, 101b and, during use, positionable between each base element 101a, 101b and the lock body 2 so as to generate upon the latter a constraint reaction to the pushing or pulling force applied on the control member 4 by said grippable elements 102a, 102b, in such a way as to prevent a shifting of the lock body 2 in the direction of application of the force, so that the lock body 2 is maintained in a stable position during the application of said force.
According to a general concept of the invention, the spacer means is associable with each base element or with the lock body and is configured to abut, respectively, against opposing sides of the lock body or abutment portions of each base element.
In accordance with one embodiment of the invention illustrated in the figures, the spacer means 103 comprises a plurality of plugs 103a which, during use, extend between each base element 101a, 101b and the lock body 2, according to a pre-established variable length of extension. With particular reference to figure 11A, the plugs are preferably made as protrusions of the base elements 101a, 101b, which can be made of various materials, for example aluminium, brass or zamak or plastic materials such as ABS, polyamide and polyarylamide.
In accordance with a particular embodiment, illustrated for example in figures 4, 8, 8A, 12, each plug is slidingly inserted into a guide 104 associable with a base element 101a, 101b and movable nearer to or farther away from the lock body 2 among a plurality of stable positions, in order to adjust the distance between the base elements and the lock body. In particular, the plug is maintained in various stable positions as a result of the friction between the guide and the plug. According to one variant embodiment, the plug is inserted flush with the guide, being of the same size. Preferably, the guide 104 is fashioned as a protrusion of the base element 101a, 101b, which can be made of various materials, for example aluminium, brass or zamak or plastic materials such as ABS, polyamide and polyarylamide. Even more preferably, the plug, too, can be made of various materials, for example aluminium, brass or zamak or plastic materials such as ABS, polyamide and polyarylamide.
Alternatively, the guide can be associated with the lock body and the plug moves nearer to or farther away from a corresponding base element, taking on a plurality of stable positions, in order to adjust the distance between the base elements and the lock body.
According to a further configuration, the guide can be made by removing material or is made directly during the production of the component it is associated with, for example the base element, typically by moulding or die-forming.
In accordance with a further aspect of the invention shown - for example - in figures 5 and 13, the system 1 advantageously comprises at least a first group of plugs having a first pre-established longitudinal extent and at least a second group of plugs having a second pre-established longitudinal extent. The term "longitudinal extent" means the length of the plugs measured in the direction that enables the base elements to be spaced from the lock body (or vice-versa), i.e. the length of the plugs measured between a portion that is proximal to a base element (or to the lock body) and a portion that is distal from said base element (or from the lock body). Advantageously, the plugs of said first and second groups are interchangeable with each other inside a housing associable with a base element or with the lock body in such a way that, when the plugs of the first group are in use, the base elements will be positioned at a first distance from the lock body, whereas when in use the plugs of the second group are in use, the base elements will be positioned at a second distance from the lock body. In accordance with this aspect of the invention, figures 5 and 13 show plugs 103a belonging to one of said two groups inserted in a housing 105 integrally fashioned in a base element 101a, 101b. Preferably, the plugs can be made of aluminium, brass or zamak or plastic materials such as ABS, polyamide and polyarylamide.
According to a further embodiment of the invention, illustrated for example in figures 3 and 14, the base elements 101a, 101b are integrally couplable with each other and with the lock body 2. Preferably, the base elements 101a, 101b are connected to each other by means of a threaded element (not visible) inserted in an opening passing through the lock body 2. Even more preferably, the opening is defined by three coaxial holes 115a, 115b, 115c, two of which fashioned in the base elements 101a, 101b and one of which fashioned in the lock body 2. In this case, the threaded element is inserted in a hole made in one of the base elements (for example, in the hole 105a) so as to engage in a thread fashioned in the hole made on the opposite base element. Advantageously, therefore, the lock body 2 is maintained packed between the base elements and can be installed also without being fixed to the front of the wing, which lends the handle system 1 greater rapidity and simplicity of installation. In accordance with an alternative embodiment, two threaded elements inserted into through holes located on opposite sides of the lock body can be used, that is to say, one threaded element for each base element. In this case, the thread is made on both sides of the lock body, so that each base element can be fixed to the latter. In this case as well, advantageously, the lock body is maintained packed between the base elements and can be installed also without being fixed to the front of the wing D, which lends the handle system 1 greater rapidity and simplicity of installation.
In accordance with a further embodiment of the invention, which may be seen for example in figures 6, 6A, 8, 8A, the system 1 comprises at least one centring member 106 configured to align the corresponding grippable elements 102a, 102b relative to a reference of the control member 4.
In accordance with one embodiment of the invention, the centring member achieves a coupling between each base element 101a, 101b and the lock body 2, which are of matching shape.
According to one embodiment of the invention shown in figures 6A, 8A, 15A, 17A, the centring member 106 comprises an abutment element 107 integrally fixable to the lock body 2 and a receiving seat 108 integrally associable with each base element 101a, 101b and of a shape corresponding to that of said abutment element 107. Preferably, the abutment element is defined by a projecting element, even more preferably a pin integrally connected to the lock body 2. The receiving seat 108 is a cavity of a shape substantially corresponding to that of the projecting element and, even more preferably, it is a hole suitable for enabling the insertion of a pin of matching size.
In accordance with an alternative embodiment (not illustrated), which is reciprocal relative to the one just described, the centring member comprises an abutment element associated with each base element and shaped to as to couple with a receiving seat associable with the lock body.
In accordance with a further embodiment of the invention, shown for example in figures 7, 8, 8A, 16, 17, 17A, the centring member 106 is integrated onto the spacer means 103. Advantageously, this configuration makes it possible to reduce the overall dimensions of the handle system and lends greater design freedom, since the space left free, alternatively, by the spacer means or by the centring member can be used to incorporate any further accessories of the system. In this regard, figures 10, 16 illustrate a handle system in which the spacer means is integrated with the centring member. Figures 2, 10, on the other hand, illustrate a handle system in which the spacer means is not integrated with the centring member.
According to the embodiment wherein the centring member 106 is integrated onto the spacer means, said centring member comprises a receiving seat 108 associable with each base element 101a, 101b and of a shape corresponding to that of a respective abutment element 107 integrally fixable to the lock body; furthermore, a plug 118 is slidingly inserted in a guide 128 positioned in proximity to the receiving seat 108. In particular, the plug 118 is movable between a plurality of stable positions nearer to or farther away from the lock body 2, in order to adjust the distance between the base elements 101a, 101b and the lock body 2.
According to an alternative variant embodiment (not illustrated), which is substantially reciprocal to the one just described, the centring member is integrated onto the spacer means in such a way as to comprise an abutment element associable with each base element and of a shape corresponding to that of a respective receiving seat associable with the lock body; furthermore, a plug is slidingly inserted in a guide positioned in proximity to the receiving seat, said plug being movable between a plurality of stable positions nearer to or farther away from each base element, in order to adjust the distance between the base elements and the lock body.
In accordance with a further embodiment of the invention, which may be better seen, for example, in figures 3 and 11, each base element 101a, 101b has a coupling portion 111 of a shape corresponding to that of an edge portion 151 of an access opening of a compartment 141 for housing the lock body 2 on the wing D. In particular, said coupling portion 111 of each base element 101a, 101b is suitable for being inserted, at least partially, in said access opening. Preferably, said coupling portion 111 comprises an edge 111a suitable for overlying a zone 151a of the edge portion 151 of the access opening of the compartment 141 housing the lock body.
The operation of the handle system according to the invention stems directly from the above-described structural elements.
Without taking away anything from the general concept underlying the invention and making particular reference to figure 14 only for greater illustrative clarity, the following is also disclosed.
The operation of one of the grippable elements or levers 102a, 102b determines a pushing force (lever 102a) or pulling force (lever 102b) on the control member 5. The pushing or pulling force is released onto both the control member 4, which shifts, as it has a degree of freedom in the direction of application of the force, and the lock body 2; more in particular, the force is released onto the lock body 2 as a result of the mechanical connection existing between the control member and the lock body itself, typically by interposition of a spring 54 (which may be better seen, for example, in figures 6 and 11) having typically the function of bringing the control member into a rest condition. The spacer means 103, which in the illustrated example comprises a plurality of plugs 103a, generates and transmits to the lock body 2 a constraint reaction to the pushing or pulling force applied on the control member 4 by said grippable elements 102a, 102b. In fact, the spacer means 103, in this case the plugs 103a extending between each base element 101a, 101b and the lock body 2, is integrally associated with the base elements 101a, 101b, which are in turn fixed integrally to the wing D, so that the lock body 2 is integrally connected to the wing. Advantageously, therefore, the spacer means is capable of preventing a shifting of the lock body 2 in the direction of application of the force, so that the lock body 2 is maintained in a stable position during the application of said force.
With particular reference to figure 14, but according to a general embodiment regarding the locks with push-pull control, it should be noted that the pushing force is typically exerted by a pusher 112 integral with a grippable element 102a and active by pressing on an abutment surface 4a of the control member 4, whilst the pulling force is typically exerted by a hook 122 integral with a grippable element 102b and engaged in a pin 4b of the control member 4. The direction of operation of the grippable elements 102a, 102b is indicated by the arrows F in figure 14.
In accordance with the invention, a method for installing a handle system on a wing D of a window or door, comprises the following steps:

preparing a lock body 2 of the type comprising a closing element 3 movable between a configuration in which it is extracted from the lock body 2 and a configuration in which it is retracted inside the lock body 2 and a control member 4 kinematically connected to the closing element 3 and subjectable to a pushing or pulling force in order to translate between at least two operating positions corresponding, respectively, to the extracted and retracted configurations of the closing element 3;
inserting the lock body 2 into a seat made on a front D1 of the wing D;
pushing the lock body 2 into the seat until the control member 4 is accessible through openings made on opposite sides of the wing D;
preparing a spacer means 103 configured to act on opposite sides of the lock body 2;
associating said spacer means 103 with the lock body 2;
positioning a pair of base elements 101 at said openings of the wing D, said spacer means 103 being interposed between the base elements 101 and the lock body 2;
integrally fixing the base elements 101 and the lock body 2 to the wing D;
connecting a pair of grippable elements 102a, 102b to respective base elements 101, in such a way that each grippable element 102 exerts a pushing or pulling force on the control member in order to bring about a translation thereof;
generating on the lock body 2, by means of said spacer means 103, a constraint reaction to the pushing or pulling force applied on the control member 4 by said grippable elements 102a, 102b, in such a way as to prevent a shifting of the lock body, so that the latter is maintained in a stable position during the application of said force.

In accordance with one embodiment of the invention, the method comprises a step of centring each grippable element 102a, 102b relative to a reference of the control member 4. By way of example, a reference of the control member can be defined by an operating portion that interacts with the grippable element or by another point of reference, even a simple notch made on the lock body, which makes it possible to establish a reference relative to the control member.
It has been ascertained in practice that the invention achieves the pre-established objects.
