?PUSHING MEANS FOR OPENING LEAVES OF SEALED FRAMES?

DESCRIPTION

TECHNICAL SECTOR OF THE INVENTION

[001] The present invention refers to push means for opening sealed doors, in particular windows or doors with hinged or sliding opening, which can be used for example in the construction sector, particularly civil and commercial, or in the naval sector, suitable for facilitating the opening of the door by providing a push that allows the inertia of the door itself and the so-called "suction effect" to be overcome.

BASIC TECHNIQUE OF THE INVENTION

[002] With the term ?sealed door? does this mean a door that allows the selective closing of a gap or opening in an essentially hermetic manner, guaranteeing thermal and acoustic sealing performance, and possibly also waterproofing? to water and air infiltrations.

[003] Sealed frames, such as doors or windows, are known, comprising a fixed frame, formed by a plurality of of profiles defining at least a substantially horizontal upper crosspiece and a pair of vertical lateral uprights suitable for being associated with an opening made on a wall, for example separating an internal environment from an external environment, and at least one door that allows selective closing and hermetic of the opening to which said window is? associated.

[004] For this purpose, called a sealed window? equipped with suitable gaskets, made in the conventional way with elastic polymeric material or rubber and/or of the magnetic type, suitably arranged on the frame and/or on the door in such a way that, in the closed position, the door is pressed against them, activating them, so that? offer the desired sealing effect.

[005] The door can then be moved by the user, using a control element, for example a handle mounted integral with the door, between a closed position, in which it rests against the seals, completely closing the opening, to an open position, in which at least a portion of the opening remains free, through different methods? operational; in fact, there are doors with "hinged" opening, i.e. hinged at an upright of the frame of the window in such a way as to be rotatable around a vertical axis defined by hinge means, or with sliding opening, i.e. movable through a movement of lateral sliding on special guides arranged on the threshold plane and/or on the upper crosspiece of the window.

[006] Possibly, the doors with hinged opening can also provide a modality? "tilt" opening, i.e. obtainable with a controlled rotation around a horizontal hinge axis.

[007] The closing position of the door is ? stably maintained by known temporary blocking means, which can be deactivated by the user by acting on the control element to open the door.

[008] The main technical problem that arises in the use of these windows and doors is? essentially due to the fact that, in the initial phase of opening the door, users often complain of difficulties? when moving the door itself away from the gaskets which, when closed, guarantee its seal.

[009] In fact, the contact between the door and the gaskets essentially generates a fictitious gluing action triggered by the pressure or by the variation in temperature or by the manufacturing tolerances, producing a phenomenon that in jargon is known as the ?sucker effect?.

[0010] To what? Furthermore, the inertia of the door itself is added, the weight of which can be significant, making handling particularly difficult, especially for people with poor physical prowess.

[0011] The above problem? furthermore aggravated in the case in which the sealed window includes a sliding door since, during the opening and closing operations of the door, the sliding that occurs between the latter and the gaskets develops a friction force that offers a It has high resistance to motion, making handling very difficult. Furthermore, this interference can, in the long run, damage the seals and cause a decline in the sealing performance of the window.

[0012] Finally, ? known is a sealed window according to patent EP3042017 by Sossai Ermenegildo comprising a fixed frame and at least one sash associated with sliding and tilting means comprising at least a pair of trolleys equipped with wheels sliding on a sliding guide located in correspondence with the upper crosspiece of the frame and tilting on it to move said sash between a closed position, in which said sash lies on a first plane abutting against first gaskets arranged on the fixed frame of the window, and an opening position, in which it lies on a second floor, parallel to said first floor, and? disconnected from said first gaskets.

[0013] Furthermore, second gaskets are associated with the lower edge of the door and are suitable to be pressed by the weight of the door itself onto the threshold plane of the opening when said door is in the closed position.

[0014] This window includes a mechanism for moving the door, operated by the handle of the door and including lifting means for lifting said door in the transition between said closing position and said opening position, disconnecting the second gaskets from the opening surface. theshold.

[0015] Such lifting means comprise an actuator pin movable axially between a rest position, in which ? substantially retracted inside a housing provided on said door when said door is in the closed position, to a push position in which ? extracted with respect to the housing and presses against abutment means associated with the fixed frame of the window to force the wheels of the trolleys out of appropriate lowered seats made on the guide and thus obtain lifting the door from the threshold level.

[0016] In practice, the coordinated action of said sliding and tilting means and of said lifting means provided on said door, triggered by the user at the time of opening through the use of the control organ, allows lift the door, detaching the second gaskets from the threshold plane, and at the same time move it on a plane parallel to the one assumed in the closed position, also moving it away from the first gaskets provided on the frame, thus overcoming the difficulty? of opening caused by the friction developed by the seals and by the suction cup effect.

[0017] Although these lifting means work in a rather satisfactory manner, they suffer from the drawback of having a large size: in fact, to allow the lifting movement of the door, the actuator pin moves axially along an inclined axis and therefore the housing provided in the door frame must have sufficient dimensions to contain it when? in the retracted position, consequently requiring the creation of a frame of considerable thickness, therefore to the detriment of the extension of the glass surface of the door itself.

SUMMARY OF THE INVENTION

[0018] Main task of what is the object of the present invention? that of overcoming the drawbacks of the prior art by devising push means for a sealed door with hinged or sliding opening, in particular but not exclusively of doors and windows, capable of facilitating the user when opening the door, allowing to overcome the inertia of the door and the so-called "suction effect".

[0019] Within the scope of the above task, an object of the present invention is that of creating a sealed window equipped with pushing means that are practical and functional, assisting the user in the opening operation of the door to make them absolutely easy and operable without any effort, even if the door is of relevant dimensions and weight.

[0020] A further task of the present invention consists in providing thrust means for a sealed window which are compact, have a reduced overall dimensions, and can therefore be incorporated into door frames having minimized thicknesses, to the advantage of the glass surface and consequently of the aesthetics, of brightness? and the saving of the quantity? of materials used to make the door itself.

[0021] Further purpose of the present invention? that of providing thrust means for a sealed window which are robust and long-lasting, and which do not require particular maintenance.

[0022] The task, the purposes and the advantages indicated above, as well as? others which will appear better in the following description, are reached by pushing means according to claim 1 and by a sealing frame equipped with pushing means as defined in claim 2.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION [0024] With reference to figures 1A and 1B, there is shown is a sealed window 1 according to a first embodiment of the invention, in particular a window with a swing opening sash, incorporating thrust means 8 according to the present invention.

[0025] Said window 1 essentially comprises a fixed frame 2 which can be associated with an opening A obtained on a wall of a building and essentially formed by a plurality of of profiles connected to each other to form at least an upper crosspiece 2A, and a first and a second upright 2B, 2C, arranged substantially vertical and parallel, and a lower crosspiece 2D.

[0026] Said window 1 also includes at least one sash 3, movable between a closed position, in which it completely closes the opening A of the wall, and an open position in which at least a portion of said opening A remains free.

[0027] Said door 3 preferably includes a flat plate 3A, advantageously made of transparent material, such as glass, and provided with an interface frame 4 on which it is a control member 99 is mounted, such as a revolving handle, thanks to which the user can? obtain the opening or closing of the door 3.

[0028] Specifically, the door 3 shown in figures 1A and 1B is of the "swing" closing type or ?flag?, i.e. ? rotatably constrained to one of said pair of uprights of said frame 2, for example said second upright 2C, around an essentially vertical hinge axis X-X, defined by appropriate and known hinge means, and the passage between the closing position (figure 1A) and the opening position (figure 1B) is conducted by means of a rotation around said hinge axis X-X.

[0029] Said window 1 also includes sealing means 5 arranged and configured in such a way that, when said sash 3 is in the closed position, said opening A is closed in a substantially hermetic manner to atmospheric agents, i.e. to water and air, also preferably providing a certain level of acoustic insulation.

[0030] In particular, preferably, said sealing means 5 comprise gaskets, for example made in a conventional manner in polymeric or rubber material or of the magnetic type, associated with at least a portion of the fixed frame 2 and/or of the door 3 and arranged in such a way as to be activated when the leaf 3? in the closed position.

[0031] Advantageously, the sealing closing position is maintained thanks to temporary locking means 9 which substantially comprise a maneuvering rod (not shown in the figures) extending vertically, inserted in the frame 4 of the door 3 and movable axially through the rotation of said handle 99, and equipped with a plurality? of locking hooks suitable to cooperate removably with corresponding retention elements provided at least on the fixed frame 2 to retain said door 3 in the closed position, in such a way that it compresses the seals 5, activating them.

[0032] To obtain the opening of the door 3? It is therefore necessary to overcome the so-called ?sucker effect? generated by the action of the gaskets and overcome the inertia of the door itself; for this purpose, advantageously, said window 1 includes pushing means 8 mounted on said sash 3 and operable via said handle 99 to move, comprising a pusher element 84 that can be moved between a first position, assumed when said sash 3 is? in the closed position, and a second position, or push position, in which it cooperates with abutment means 24 provided on said fixed frame 2 to provide the door 3 with an opening push S suitable for distancing it, i.e. moving it away, from said frame 2 and deactivate the seals 5, assisting the user in the initial opening phase of the door itself.

[0033] In particular, as shown in figure 2, said pushing means 8 essentially comprise first actuating means 80, operationally associated with said handle 99 and suitable for sliding a first sliding element 83, such as a slide, along a first sliding direction V1 advantageously vertical to integrally move said pusher element 84, preferably formed by a rigid pin, along a second sliding direction V2 inclined with respect to the first sliding direction V1.

[0034] Preferably, said push means 8 are contained inside a housing 18 obtained in the interface frame 4 of said door 3, so that, in the first position, the pusher pin 84 is substantially retracted inside the ?housing 18, and in the second position, or pushing position, it projects from said housing 18, abutting against said abutment means 24.

[0035] The fact that said first slide 83 moves along a vertical direction V1 to urge the movement of the pusher pin 84 along an inclined sliding direction V2? advantageous in that it allows the width of the housing 18 and therefore of the interface frame 4 of the door 3 to be limited, minimizing its bulk in favor of the extension of the transparent surface 3A of the same.

[0036] Advantageously, as shown in figures 3A and 3B, said abutment means 24 comprise a abutment surface 24A arranged on the fixed frame 2 of the window 1 and suitably arranged to provide, by cooperating with the pusher element 84, a thrust of S opening on door 3 itself; in particular, in the case of a window 1 with a leaf 3 with hinged opening, said thrust means 8 and said abutment means 24 are arranged and configured in such a way as to impart to the leaf 3 a thrust S having a prevalent component along one direction of translation T1 essentially horizontal and transversal with respect to the plane of the door 3 in the closed position, so as to facilitate the opening rotation of the door around said hinge axis X-X.

[0037] Referring again to figure 2, said first operating means 80 are preferably formed by a toothed wheel, rotatable integrally with the handle 99 thanks for example to a coupling with a polygonal pin 99B inscribed in it, equipped with a first toothing 81 comprising at least one radial engagement tooth 81A suitable for cooperating with a corresponding first linear toothing 82 obtained on said first sliding element 83 to activate its movement.

[0038] Advantageously, said first linear toothing 82 includes at least one groove 82A defined between a first and a second abutment tooth 82B, 82C, said groove 82A having an increased width compared to the width of the engagement tooth 81A.

[0039] According to an advantageous feature of the present invention, the sliding movement of the first slide 83? transmitted to the pusher pin 84 thanks to transmission means 85 advantageously formed by a flexible but substantially axially rigid body, i.e. essentially preferably inextensible and incompressible, therefore suitable for transmitting traction and thrust forces, connected with a first end 85A to the first slide 83 and with the end? opposite 85B to the pusher pin 84.

[0040] In particular, advantageously, said transmission means 85 are suitable for sliding inside a shaped guide 88 arranged in the housing 18 and configured to deviate the sliding direction V2 of said pusher pin 84 with respect to the sliding direction V1 of the first sled 83.

[0041] Said transmission means 85 can for example comprise a chain formed by a plurality? of modular elements articulated to each other, as shown in figure 2; alternatively, said transmission means 85 can be formed by a flexible shaft or a push-pull cable made of polymeric or metallic material or by any other means or device capable of performing the same function.

[0042] In practice, the rotation of said first toothed wheel 80, whose engagement tooth 81A meshes with the corresponding first linear toothing 82 provided on said first slide 83, determines the movement of the first slide 83 along the vertical sliding direction V1 which in turn it moves integrally, thanks to the transmission means 85, the pusher pin 84 along the inclined sliding direction V2, from the retracted position to the pushed-out position.

[0043] The first slide 83 ? furthermore advantageously associated with a first elastic contrast means 86, such as for example a first compression spring, suitable for returning the pusher pin 84 to the retracted position after having performed the pushing function, and with a second elastic contrast means 87, such as for example a second compression spring, suitable for allowing the resetting of said thrust means 8.

[0044] Advantageously, said handle 99? furthermore suitable for moving temporary locking means 9, not shown in the figures relating to the first embodiment of the invention, comprising second operating means, such as a second toothed wheel, arranged coaxial with respect to said first toothed wheel 80, and also operable rotated by moving the handle 99.

[0045] Said second toothed wheel? provided with a third circumferential toothing suitable for engaging with a fourth toothing obtained on a second sliding element, such as a second slide, operationally connected to at least one temporary locking rod equipped with at least one locking hook, and preferably at least one pair, suitable to cooperate removably with corresponding retention elements provided at least on an upright 2B of the fixed frame 2 to retain said door 3 in the closed position, in such a way that it compresses the seals 5, activating them.

[0046] Preferably, said second drive wheel and said second slide are also arranged inside the same housing 18 in which said thrust means 8 are inserted, for example in a compartment suitably separated by a plate that divides it longitudinally .

[0047] The operation of said thrust means 8 when applied to a sash 3 of a sealed window 1 with swing opening? the following: when leaf 3? in the closed position (figure 3A), the handle 99 assumes a first position, in which it is preferably arranged vertically, with the end? free movement 99A for example facing downwards, and said pushing means 8 are in an initial condition, with the pusher pin 84 in the first position, i.e. substantially retracted inside said housing 18 (figures 4A and 6A); the locking hooks of the temporary locking means 9 are in engagement with the corresponding retaining elements and keep the door 3 firmly in contact with said gaskets 5, activating the sealing effect.

[0048] Furthermore, in the initial condition, the engagement tooth 81A? received in the groove 82A of the first linear toothing 82 and arranged to rest against said first abutment tooth 82B, maintaining the first slide 83 in a position in which it presses upon compression said second elastic means 87 (figure 6A).

[0049] To open the door 3, the user rotates the handle 99, advantageously gripping an end portion of it. 99A; this movement involves the coordinated activation of said door thrust means 8 and of the temporary locking means of the door.

[0050] In fact, as shown in figure 6B, by imposing a rotation on the handle 99 of a first angle ? equal to 30 for example? with respect to the initial position, the latter also rotates in a concordant direction said first drive wheel 80, and consequently said engagement tooth 81A, and said second drive wheel of the temporary locking means; thanks to the increased width of said groove 82A, this rotation is not initially useful for operating the pusher pin 84 but the simultaneous rotation of the second drive wheel allows a vertical translation to be imposed on the second slide and therefore on the rod of the temporary locking means 9 and, consequently, of the locking hooks integral with it, starting the release of the latter from the corresponding retaining elements.

[0051] With a further rotation of the handle 99 for example by an angle ? about 60? with respect to the initial position (figure 6C), said engagement tooth 81A reaches said second abutment tooth 82C and, from that moment, engages with the first linear toothing 82; therefore, further rotations of the opening handle 99 impose a sliding of the first slide 83 along the vertical sliding direction V1 and therefore, through said transmission means 85, the movement of said pusher pin 84 towards the pushed-out position, in contrast with the action of said first elastic means 86.

[0052] As the pusher pin 84 emerges from the housing 18 (figure 4B), its end? of the head 84A insists on the surface 24A of the abutment element 24 provided on the fixed frame 2 (figure 3B), providing a thrust S to the door 3 in the translation direction T1 which allows the door itself to be moved away from the frame 2, in the opening direction, deactivating the seals 5 and thus allowing the user to effortlessly start and complete the opening movement of the door 3 itself.

[0053] For this purpose, as shown in figures 3A and 3B, said pusher pin 84? advantageously arranged in such a way that the passage between the first position and the second position occurs along a direction parallel to the plane of the door 3, and is configured in such a way that its head surface 84A and the abutment surface 24A of said abutment means 24 are essentially counter-inclined.

[0054] Alternatively, as shown in figures 5A and 5B, said pusher pin 84 can? be arranged in such a way that the passage between the first position and the second position occurs along a direction essentially orthogonal to the plane of the leaf 3, insisting against a counter surface 24A parallel to the plane of the leaf 3.

[0055] When has the handle 99 rotated through an angle equal to approximately 75? with respect to the initial position (figure 6D), the engagement tooth 81A rotatably reaches said second abutment tooth 82C of the first linear toothing 82, which substantially corresponds to the operating condition of maximum thrust, with the pusher pin 84 in the second position.

[0056] As soon as the engagement tooth 81A rotatably passes the second stop tooth 82C, the first elastic means 86 returns the first slide 83 to the initial position, recalling the pusher pin 84 to the first position (figure 6E), retracted inside of the housing 18, and the handle 99 freely completes its rotation until it reaches the final opening position, in which it is preferably arranged horizontally.

[0057] When the user wishes to close the door 3 tightly, he returns it to the closed position, and starts the rotation of the handle 99 in the direction of rotation opposite to that of opening, so as to bring the ?extremity? 99A down.

[0058] When does the handle 99 reach a rotation angle? about 75? with respect to the closed position, the radial engagement tooth 81A of the toothed wheel 81 integral with it overcomes the second abutment tooth 82C of the first linear toothing 82 obtained on the slide 83 and fits into the groove 82A (figures 6D and 6C); at this point the rotation of the handle 99 corresponds to the movement of the tooth in the groove 82A (figure 6B) which allows the activation of the temporary locking means 9, i.e. the backward vertical translation of the second slide integral with the rod and, consequently, the ?engagement of the locking hooks integral with it with the corresponding retaining elements arranged on the frame 2.

[0059] The further rotation of the handle 99, until the initial closing position is reached, causes that the engagement tooth 81A collides with the first tooth 82B of the first linear toothing 82, causing the first slide 83 to slide upwards, in contrast with the action of the second elastic means 87, allowing the push 8 in the initial non-operational condition and to reset the pusher pin 84 (figure 6A).

[0060] With reference to figures 7A and 7B, ? instead shown is a sealed window 10 according to a second embodiment of the present invention, specifically a door with a sliding opening leaf, incorporating push means 8 according to the present invention, respectively in a closed position and in an open position.

[0061] As shown in the figures, when opened, the leaf 3 overlaps with a fixed leaf; alternatively, door 3 can? be retractable, i.e. when opened it enters a cavity created in the wall.

[0062] As for the previous embodiment, said window 10 includes a fixed frame 2, essentially formed by at least one upper crosspiece 2A, a pair of parallel vertical mounts 2B, 2C, and at least one door 3 provided with a frame of interface 4, and can be slidably moved between a closed position and an open position thanks to sliding means (not shown) comprising a pair of carriages associated with the lower edge of the door and resting in an oscillating or non-oscillating manner on a horizontal track arranged in correspondence with the threshold plane P, which allow the sliding of the door between a closed position and a maneuvering and opening position.

[0063] Otherwise, if said sealed window 10 is made as envisaged in patent EP3042017 of , said door 3? supported and movable by means of sliding and tilting means formed by a pair of trolleys, sliding on a track arranged in correspondence with the upper crosspiece 2A and tilting on it, and is without a guide on the ground, the door 3 being able to rest directly on the threshold surface P in the closed position.

[0064] In any case, sealing means 5, such as suitable gaskets, are associated with at least a portion of the fixed frame 2 and/or the door 3 and can be activated when the door 3 is in the closed position to be able to hermetically close the opening at which the window 10 is associated.

[0065] According to an advantageous feature of the present invention, the window 10 further comprises thrust means 8? according to the invention, mounted on said door 3 and suitable for assisting the user when opening the latter in such a way as to overcome the suction cup effect generated by the sealing means 5 and the inertia of the door itself.

[0066] As for the previous embodiment, said thrust means 8? they include first operating means 80?, such as a first toothed wheel, operatively connected to the handle 99 and suitable for sliding a first sliding element 83 along a first sliding direction V1 in vertical use (figure 8).

[0067] Said first sliding element 83? connected via flexible transmission means 85 to a pusher element 84, such as a rigid pin, movable along a second sliding direction V2 inclined with respect to the first sliding direction V1 between a first position, in which ? substantially retracted into a housing 18 provided on said door 3 when said door 3 is in the closed position, and a second position, or push position, in which ? extracted with respect to the housing 18 and presses against abutment means 24 associated with said fixed frame 2 to give the door 3 an opening push S useful for moving it away from the frame 2, deactivating the effect of the sealing means 5.

[0068] In this embodiment, advantageously, said thrust means 8? they provide the leaf 3 with a thrust S including, in addition to a component along a translation direction T1 essentially horizontal and transversal with respect to the lying plane of the leaf 3 when in the closed position, also a component along a vertical direction T2, to allow for the door 3 to rise with respect to the closed position and allow its movement via the sliding means. In this case, therefore said abutment means 24 are equipped with an appropriately inclined abutment surface 24A.

[0069] According to an advantageous feature of the invention, as shown in greater detail in figures 9A and 9B, said window 10 also includes safety clamping means 6 and temporary locking means 9, the latter operable by the user through an organ control 99 provided on the door 3, in a coordinated manner with the thrust means 8, to selectively hold the door in the closed position and obtain the activation of the seals 5.

[0070] Said safety locking means 6 preferably comprise a cylinder lock 61, the latter being equipped with actuation means which can be operated by inserting a key inside a slot 61A provided in the cylinder itself to transmit the movement rotary of the key to the throw 62 of the lock, so that? the latter can move, in a known and conventional way, between a retracted position and an extracted position.

[0071] Said temporary locking means 9 comprise second driving means 90, such as a second toothed wheel, arranged coaxial with respect to said first toothed wheel 80?, and which can also be operated in rotation by the movement of the handle 99.

[0072] Said second toothed wheel 90 ? provided with a second circumferential toothing 91 suitable for engaging with a second linear toothing 92 obtained on a second sliding element 93, such as a slide, operationally connected to at least one temporary locking rod 94 equipped with at least one locking hook 95, and preferably at least one pair, as shown in figures 12A and 12B, suitable for removably cooperating with a corresponding retention element 96 provided at least on an upright 2B of the fixed frame 2 to retain said door 3 in the closed position, such that the same compress the seals 5, activating them.

[0073] Preferably, as shown in figure 9B, a dividing plate 98 longitudinally divides said housing 18 into two compartments, in which the first push means 8 are housed. and said temporary blocking means 9 are housed in the second.

[0074] The first gear wheel 80? comprises a first circumferential toothing 81, suitable for engaging with a first linear toothing 82? provided on the first slide 83. Unlike the first embodiment of the present invention, said first circumferential toothing 81 has a plurality of of teeth, among which at least a first engaging tooth 81A having a greater radial extension than the other teeth, and a last engaging tooth 81B.

[0075] Advantageously, said first linear toothing 82? does it include a plurality? of grooves, including at least a first groove 82A defined between a first and a second abutment tooth 82B, 82C, said groove 82A having an increased width compared to the width of one of the teeth of said first circumferential toothing 81, and a last throat 82D.

[0076] The operation of said thrust means 8? when applied to a door 3 of a sealed window 10 with sliding opening? the following: when leaf 3? in said closed position (figures 7A and 11A), the handle 99 assumes a first position, in which it is preferably arranged vertically, for example with the end? free movement 99A preferably facing upwards, and said thrust means 8? they are in the initial non-operational condition, with the pusher pin 84 in the first position, substantially retracted inside said housing 18 (figure 10A); the locking hooks 95 of the temporary locking means 9 are in engagement with the corresponding retaining elements 96 and keep the door 3 firmly in contact with said gaskets 5, activating the sealing effect.

[0077] The safety clamping means 6 are in the clamping configuration, in which the throw 62 is in an extracted position, inserted inside the delivery engagement means 63 provided on the fixed frame 2 of the window 1?.

[0078] Furthermore, in the initial condition, the thrust means 8? are they arranged such that the first engaging tooth 81A is received in the groove 82A of the first linear toothing 82? and arranged to rest against said first abutment tooth 82B, maintaining the first slide 83 in a position in which it presses said second spring 87 into compression.

[0079] To obtain the opening of the door 3, the user moves the key in a conventional way inside the slot of the cylinder 61, recalling the delivery 62 to the retracted position with respect to the engagement seat 63, thus deactivating the means of safety clamp 6 (figure 10B).

[0080] Gripping the extremity? maneuver 99A of the handle 99, the user drags the latter into rotation to obtain the opening of the door 3; this movement involves the coordinated activation of said thrust means 8? of the door and of said temporary blocking means 9 (figures 10C - 10D).

[0081] In fact, by imposing a rotation on the handle 99 of a first angle ? with respect to the initial position, the latter rotates in a concordant direction, also known as the first drive wheel 80? and said second driving wheel 90; thanks to the increased width of said groove 82A, the rotation of the first drive wheel 80? Not ? initially useful for moving the pusher pin 84 but at the same time the second circumferential toothing 91 of said second drive wheel 90 meshes with the second linear toothing 92 of the second slide 93, allowing a translation in a direction V1 in vertical use to be imposed on the push rod locking 94 and, consequently, to said locking hooks 95 integral with it, starting the release of the latter from the corresponding retaining elements 96.

[0082] With a further rotation of the handle 99 with respect to the initial position, said first engagement tooth 81A reaches said second abutment tooth 82C and, from that moment, further rotations of the opening handle 99 impose a sliding of the first slide 83 along the vertical sliding direction V1 and therefore, through said transmission means 85, the movement of said pusher pin 84 along a direction V2 towards the extracted position, in contrast with the action of said first spring 86.

[0083] As the pusher pin 84 emerges from the housing 18, its end? of the head 84A insists on the surface 24A of a striker element 24 provided on the fixed frame 2, providing an opening thrust S to the door 3 which allows the door itself to be moved away from the frame 2, deactivating the seals 5 and thus allowing the The user can effortlessly complete the opening movement of the door 3 itself.

[0084] Advantageously, said pusher pin 84? arranged in such a way that the passage between the first position and the second extracted position occurs along a direction parallel to the plane of the door 3, and is configured in such a way that its head surface 84A and the abutment surface 24A of said abutment element 24 are essentially counter-inclined, such that the thrust S imparted presents, in addition to a translation component along a translation direction T1 , useful for deactivating the suction cup effect of the seals 5, also a component along a vertical direction T2, such as to allow the lifting of the door 3 and therefore the activation of the sliding means that allow its movement.

[0085] When has the handle 99 rotated through an angle? equal to approximately 170? with respect to the initial position, the last tooth 81B of the first circumferential toothing 81 of the thrust means 8? it is rotatably received in the last groove 82D of the first linear toothing 82, which substantially corresponds to the operating condition of maximum thrust, with the pusher pin 84 in the extracted position (figure 10C).

[0086] As soon as the last engagement tooth 81B rotatably protrudes from the last groove 82D of the first linear toothing 82 following the further rotation of the handle 99, the first circumferential toothing 81 and the first linear toothing 82 decouple and the first elastic means 86 returns the first slide 83 to the initial position, thus recalling the pusher pin 84 to the retracted position (figure 10D).

[0087] The handle 99 then freely completes its rotation until it reaches the final opening position, in which it is preferably arranged vertically, with the end? free 99A facing downwards (figures 7B and 11B).

[0088] When the user wishes to close the door 3 tightly, he slides it back to the closed position, and starts rotating the handle 99 in the direction of rotation opposite to that of opening, so as to bring the extremity? 99A upwards.

[0089] During the rotation of the handle 99, the second drive wheel 90 forces the sliding of the second slide 93 in the direction opposite to the opening direction (figure 10E), recalling the locking rod 94 in such a way that the locking hooks 95 integral with it engage with the corresponding retention elements 96 provided on the frame 2.

[0090] At the same time, the rotation of the first drive wheel 80? does it? that the first circumferential toothing 81 engages with the first linear toothing 82 provided on the first slide 83, causing it to slide along the direction V1 but in the opposite direction, i.e. upwards, in contrast with the action of the second spring 87.

[0091] When the first engagement tooth 81A rotatably overrides the second abutment tooth 82C of the first linear toothing 82, the second spring 87 pushes the slide 83 to the starting position, returning the thrust means 8? in the initial non-operational condition and consequently rearming the pusher pin 84 (figure 10F).

[0092] At this point the closing procedure can? be completed by activating the safety clamping means 6 to move the throw 62 of the safety lock to the extracted position, so that it is received in the engagement seat 63 provided in the frame 2 (figure 10G).

[0093] Advantageously, on the door 3 you can Furthermore, a kinetic accumulator device 30 must be provided, suitable for accumulating energy deriving from the inertia of the door during the closing phase, advantageously controlling its movement, and in the opening phase progressively releasing the accumulated energy, providing a push in the sliding direction T3 of the door, and thus contributing to the reduction of the force required from the user to open the door.

[0094] As shown in figures 12A and 12B, said kinetic accumulator device 30 preferably comprises a mounting plate 31, suitable for being fixed to the leading lateral edge of the door, on which there is an internally threaded bush 32 is mounted, suitable to be received in the thickness of the door itself.

[0095] Inside the bush 32? advantageously screwed in an adjustable manner a sleeve 33 into which are coaxially inserted a first elastic element 34, such as a helical spring advantageously operating in compression, a second elastic element 35, such as a helical spring advantageously operating in tension and finally a pin 36, equipped of a hollow cylindrical body 36A and a flat head 36B, suitable for insisting on a counter element 37 provided on an upright 2B of the frame 2 of the window 10.

[0096] Said second spring 35? received in the hollow body 36A of said pin 36 and is bound, with a first extremity? 35A at the bottom of said bush 31, and with the end? opposite 35B to pin 36, in proximity? of the flattened head 36B thereof.

[0097] The first spring 34 ? instead arranged externally to the body 36A of the pin 36 in such a way as to abut with the first end? 34A, against the bottom of the bushing 32, and with the end? opposite 36B can be subjected to compression by the head of the pin 36.

[0098] The second spring 35 constantly recalls the pin 36 to the retracted position, while the first spring 34 ? suitable for accumulating elastic energy during closing, and then releasing it when the door is opened 3.

[0099] By appropriately selecting the springs 34, 35 and the axial position of the sleeve 33? advantageously it is possible to regulate the force developed by the device 30, also allowing it to be easily adapted for use on doors having different weights and dimensions.

[00100] Finally, in figures 14A and 14B? shown is a sealed window 100 according to a third embodiment of the invention, equipped with a door 3 with sliding opening equipped with sliding and tilting means 7 including sliding and tilting trolleys 71 on an upper track 72 and lower accompanying means, advantageously comprising a roller 77 sliding in a guide profile 78 and accompanying cams to guide the opening movement of the door (figures 15A, 15B, 15C, 16A, 16B and 16C).

[00101] In the figures? The external side has been indicated with the letter E and the internal side with the letter I.

[00102] Said window 100 includes thrust means 8?? (not shown in the figures) mounted on said door 3, operationally connected to said control member 99 and suitable for operating, in sliding, a first sliding element 83 along a first sliding direction V1 in vertical use, to integrally move a pusher element 84 ? between a first position, assumed when said leaf 3? in the closed position, and a second position, in which it interacts with feedback means 24? bound to said fixed frame 2 to provide the door 3 with an opening thrust S useful for distancing it, i.e. moving it away, from said frame 2.

[00103] Said thrust means 8?? comprise first drive means 80? essentially formed by a wheel which can be rotated by said control member 99 and equipped with a first circumferential toothing 81 comprising at least a first engagement tooth 81A suitable for cooperating with a corresponding first linear toothing 82? obtained on said sliding element 83.

[00104] However, in this embodiment the pusher element 84? ? formed by an inclined hook (figures 17A and 17B), movable integrally with said first slide 83 along a vertical direction V1 and suitable for cooperating with abutment means 24? to provide an opening thrust S to the door 3 comprising a component along the direction of sliding movement T3 of the door, and a component along a translation direction T1 essentially horizontal and transversal with respect to the lying plane of the door 3 in the closure.

[00105] For this purpose, said matching means 24? advantageously comprise an engagement cavity 25 provided with a front guide slot 25A equipped with lateral edges inclined towards the outside E to accompany the movement of the door in the translation direction T1 and a bottom wall 25B inclined to accompany the movement of the ?leaf 3 in the direction of sliding movement of the leaf T3 (figures 18A and 18B).

[00106] When the leaf 3 of the window 100 is in the closed position, called pusher hook 84? ? inserted inside the cavity 25 (figures 19A, 19B). To move the door 3 open, the user rotates the handle 99 which activates said thrust means 8??, moving the first slide 83 in sliding along said direction V1.

[00107] The pusher hook 84?, mounted integral with said first slide 83, is then moved along the same sliding direction V1, progressively emerging from the engagement cavity 25 with a movement advantageously guided by the inclined lateral edges of the guide slot 25A and simultaneously also cooperating with the bottom wall 25B (figures 20A and 20B) of the cavity 25, in such a way as to impart a thrust S to the door 3 both in the direction of transversal translation T1 and also in the direction of sliding movement of the door. door T3, thus allowing the user to effortlessly start the opening movement of the door 3 by moving it away from the frame 2, overcoming the inertia of the door 3 and the suction cup effect given by the action of the seals 5.

[00108] Differently from the previous embodiments, said thrust means 8?? they do not have elastic means n? means of transmission.

[00109] From the foregoing, it is therefore clear that the present invention achieves the objectives and advantages initially envisaged: thrust means have in fact been devised for a sealed sash, suitable for incorporation into a window and door, which make it possible to facilitate the user when opening the door, allowing the inertia of the door itself and the so-called "suction effect" to be overcome.

[00110] Advantageously, the pushing means according to the present invention are practical and functional, assisting the user in the opening operation of the door to make it absolutely easy and operable without any effort, even if the door is of relevant dimensions and weight.

[00111] Furthermore, the thrust means according to the present invention are very compact, taking up very little space, and can therefore be incorporated into door frames with minimized thicknesses, to the advantage of the glass surface and consequently of the aesthetics, brightness and and the saving of the quantity? of materials used to make the door itself.
