Definitions

  • the present invention refers to thrust means for opening weathertight doors or windows, in particular door or windows having wings with abutting or sliding opening, used for example in the building industry, in particular in domestic and commercial premises, or in the naval industry, designed to facilitate the opening of the door or window by providing a thrust that makes it possible to overcome the moment of inertia of the door or window and to break the suction.
  • weathertight wing refers to a door or window wing that allows the selective closing of an aperture or opening in an essentially airtight manner, guaranteeing thermal and acoustic sealing, as well as tightness against moisture and air drafts.
  • Weathertight windows and doors which comprise a fixed frame, formed with a plurality of elements defining at least one upper crosspiece substantially horizontal and a pair of vertical side elements adapted to be associated to an opening made on a wall, for example separating an internal space from an external space, and at least one wing that allows the selective and airtight closing of the opening to which said door frame is associated.
  • said window or door is provided with appropriate gaskets or sealing strips of conventional construction, made with elastic polymeric material or rubber and/or of magnetic type, placed on the frame and/or on the door or window wing so that, in the closed position, the wing is pressed against them and activates them so that they provide the desired sealing effect.
  • the wing can then be moved by the user, by means of a control member, for example a handle mounted integrally to the wing, between a closed position, wherein it lies in abutment against the sealing strips, closing the opening completely, and an opening position, wherein at least one portion of the opening remains free, by means of different operative modes; there are in fact wings with "abutting" opening, that is hinged on a vertical member of the window or door frame so as to be rotatable around a vertical axis defined by hinge means, or with a sliding opening, that is, movable by means of a lateral sliding movement on appropriate guides arranged on a threshold plane and/or on the upper cross member of the door frame.
  • a control member for example a handle mounted integrally to the wing
  • wings with abutment opening can also be provided with a "vasistas-type" opening, that is, one obtained with a controlled rotation around a horizontal hinge axis.
  • the wing closed position is maintained stably by temporary locking means that are deactivated by the user by means of the control member to obtain the opening of the wing.
  • the weathertight door or window includes a sliding wing since, during the wing opening and closing operations, the sliding that occurs between the latter and the sealing strips generates a friction that engenders a high resistance to the movement, making its operation rather difficult. Moreover, this interference can eventually harm the sealing strips and cause a decline in the sealing performance of the wing.
  • a weathertight door comprising a fixed frame and at least a wing associated to sliding and tilting means comprising at least a pair of trolleys equipped with wheels running on a guiding rail placed at the upper cross member of the fixed frame and pivoting on it to move said wing between a closed position, in which it lies on a first plane abutting against first sealing strips arranged on the fixed frame of the wing, in which it lies on a second plane, parallel to said first plane, and is separated from said first sealing strips.
  • second sealing strips are associated to the lower edge of the wing and are adapted to be pressed by the weight of the wing itself on the threshold plane of the opening when said wing is in the closed position.
  • Said door includes a mechanism for moving the wing, operated by means of the wing control handle and comprises lifting means for lifting said wing in the passage between said closed position and said open position, disconnecting the second sealing strips from the threshold plane.
  • These lifting means comprise an actuating pin axially movable between an idle position, in which it is substantially retracted in a housing seat provided on the wing when said wing is in the closed position, and a thrust position in which it is extracted from the housing and bears against abutment means associated with the fixed frame of the door to force the wheels of the trolleys out of recessed seats provided on the guide and thus obtain the lifting of the wing from the threshold plane.
  • the coordinated action of said sliding and tilting means and of said lifting means provided on said door wing caused by the user when opening the door using the control member, makes it possible to lift the wing, detaching the second sealing strips from the threshold plane, and at the same time to move it to a plane parallel to the plane occupied in the closed position, moving it also away from the first sealing strips provided on the frame, thereby overcoming the problems found when opening it, such as the friction generated by the sealing strips and the "vacuum effect".
  • the main objective of the subject matter of the present invention is to overcome the problems of the prior art by devising thrust means for an abutting or sliding weathertight wing, in particular but not exclusively of a door or a window, capable of facilitating the user when opening the wing, making it possible to easily overcome the inertia of the wing and break the suction.
  • one purpose of the present invention is to realize a weathertight door or window provided with practical and functional thrust means that help the user in the wing opening operations, making them absolutely easy and manageable without any effort, even when the wing is particularly large and heavy.
  • a further task of the present invention is to provide compact thrust means for a weathertight door or window, having small dimensions that allows them to be integrated in wing frameworks of reduced thickness, to the advantage of the glazed surface and consequently of the appearance, lightness and economy in the quantity of materials used to make the door or window.
  • a further purpose of the present invention is to provide strong and durable thrust means for a weathertight door or window without requiring any particular maintenance.
  • thrust means according to claim 1 and with a weathertight door or window provided with thrust means as defined in claim 2.

  • Said window 1 also includes at least one wing 3, movable between a closed position, in which it closes completely the opening A on the wall, and an open position in which at least one portion of said opening A remains free.
  • Said wing 3 preferably comprises at least one flat plate 3A, advantageously made of transparent material, such as glass, and provided with an interfacing framework 4 on which is mounted a control member, such as a rotating handle, thanks to which the user can obtain the opening or closing of the wing 3.
  • a control member such as a rotating handle
  • the wing 3 shown in figures 1A and 1B is of the "side hung" or “abutting” type, that is, it is rotatably connected to one of said pair of vertical members of said fixed frame 2, for example, said second vertical member 2C, around an essentially vertical hinge axis X-X, defined by appropriate and known hinge members, and the passage between the closed position ( figure 1A ) and the open position ( figure 1B ) is performed by a rotation around said hinge axis X-X.
  • Said weathertight window 1 also comprises sealing means 5 arranged and configured so that, when said wing 3 is in a closed position, said opening A is closed to weather agents, i.e., water and air, in an essentially hermetic manner, also preferably providing a certain level of acoustic insulation.
  • weather agents i.e., water and air
  • said sealing means 5 include sealing strips, for example made conventionally of polymeric material or rubber, or of magnetic type, associated to at least one portion of the fixed frame 2 and/or to the wing 3 and arranged so as to be activated when the wing 3 is in the closed position.
  • the weathertight closed position is maintained thanks to temporary locking means 9 that substantially include an operating rod (not shown in the figures) extending vertically, inserted in the framework 4 of the wing 3 and axially movable through the rotation of said handle 99, and provided with a plurality of locking hooks adapted to removably cooperate with corresponding holding elements provided at least on the fixed frame 2 to hold said wing 3 in the closed position, so that said wing presses the sealing strips 5 and activates them.

  • said weathertight window 1 includes thrust means 8 mounted on said wing 3 and actuated by means of said handle 99 to move, comprising a thrust member 84 movable between a first position, occupied when said wing 3 is in the closed position, and a second position, or thrust position, in which it cooperates with abutment means 24 provided on said fixed frame 2 to give the wing 3 an opening push S adapted to space it, that is move it away from said fixed frame 2 and deactivate the sealing means 5, helping the user in the initial step of opening the wing.
  • thrust means 8 mounted on said wing 3 and actuated by means of said handle 99 to move, comprising a thrust member 84 movable between a first position, occupied when said wing 3 is in the closed position, and a second position, or thrust position, in which it cooperates with abutment means 24 provided on said fixed frame 2 to give the wing 3 an opening push S adapted to space it, that is move it away from said fixed frame 2 and deactivate the sealing means 5, helping the user in
  • said thrust members 8 include essentially first driving means 80, operatively associated with said handle 99 and adapted to drivingly slide a first sliding element 83, such as a slide, along a first sliding direction V1, advantageously vertical, to move integrally said thrust member 84, preferably formed by a rigid pin, along a second sliding direction V2 inclined with respect to the first sliding direction V1.
  • said thrust means 8 are contained inside a housing 18 obtained in the interface framework 4 of said wing 3, so that, in the first position, the thrust pin 84 is essentially retracted inside the housing 18, and in the second position, or thrust position, it projects from said housing 18, bearing upon said abutment means 24.
  • said first slide 83 moves along a vertical direction V1 to urge the movement of the thrust pin 84 along an inclined sliding direction V2 is advantageous because it makes it possible to reduce the width of the housing 18 and thus of the interface framework 4 of the wing 3, minimizing its encumbrance in favour of the extension of the transparent surface of the plate 3A of the wing 3.
  • said abutment means 24 include an abutment surface 24A positioned on the fixed frame 2 of the window 1 and properly arranged to provide, cooperating with the thrust member 84, an opening thrust S on the wing itself 3; in particular, in the case of a door or window 1 with a swing opening, said thrust means 8 and said abutment means 24 are arranged and configured so as to apply on the wing 3 a thrust S having a prevalent component along a direction of translation T1 essentially horizontal and transversal with respect to the plane of the wing 3 in the closed position, so as to facilitate the opening rotation of the wing around said hinge axis X-X.

  • the rotation of said first gear wheel 80 determines the movement of the first slide 83 along the vertical sliding direction V1, which in turn moves integrally, thanks to the transmission means 85, the thrust pin 84 along the inclined sliding direction V2, from the retracted position to the extracted thrust position.

  • Said first sliding element 83 is connected through flexible transmission means 85 to a thrust 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 it is substantially retracted in a housing 18 provided on said wing 3 when said wing 3 is in the closed position, and a second position, or thrust position, in which it is extracted with respect to the housing 18 and bears down on abutment means 24 associated with said fixed frame 2 to give to the wing 3 an opening thrust S useful to move the wing away from the frame 2, deactivating the effect of the sealing means 5.
  • a thrust element 84 such as a rigid pin
  • said thrust means 8' apply to the wing 3 a thrust S comprising, in addition to a component along a translation direction T1 essentially horizontal and transversal with respect to the lying plane of the wing 3 when in the closed position, a component along a vertical direction T2, to enable the wing 3 to rise with respect to the closed position and allow the movement of the wing through the sliding means. Therefore, in this case, said abutment means 24 are provided with an appropriately inclined abutment surface 24A.
  • said weathertight window 10 also comprises safety locking means 6 and temporary locking means 9, the latter actuated by the user by means of a control device 99 provided on the wing 3, in a manner coordinated with the thrust means 8, to selectively hold the wing in a closed position and actuate the sealing strips 5.
  • Said safety locking means 6 preferably include a cylinder lock 61, provided with actuating means operated by inserting a key inside a keyhole 61A provided in the same cylinder to transmit the rotational movement of the key to a lock member, so that the lock member can move conventionally between a retracted position and an extracted position.
  • Said temporary locking means 9 include second driving means 90, such as a second gear wheel, arranged coaxially with respect to said first gear wheel 80', which is also driven to rotate through the movement of the handle 99.
  • second driving means 90 such as a second gear wheel, arranged coaxially with respect to said first gear wheel 80', which is also driven to rotate through the movement of the handle 99.
  • Said second gear wheel 90 is provided with a second circumferential toothing 91 adapted to engage with a second linear toothing 92 formed on a second slidable element 93, such as a slide, operatively connected to at least one temporary locking rod 94 provided with at least one locking hook 95, and preferably at least a pair, as shown in figures 12A and 12B , adapted to removably cooperate with a corresponding retaining element 96 provided on at least one vertical member 2B of the fixed frame 2 to retain said wing 3 in the closed position, in a way that enables it to compress the sealing elements 5, activating them.
  • a dividing plate 98 divides said housing 18 longitudinally in two compartments, in which in the first compartment are housed said thrust means 8' and in the second are housed said temporary locking means 9.
  • the first gear wheel 80' includes a first circumferential toothing 81, adapted to engage with a first linear toothing 82.' provided on the first slide 83.
  • said first circumferential toothing 81 has a plurality of teeth, among which there is at least a first engaging tooth 81A having a larger radial extension with respect to the other teeth, and one last engaging tooth 81B.
  • said first linear toothing 82' includes a plurality of grooves, among which there is at least one first groove 82A defined between a first and a second abutment tooth 82B, 82C, said groove 82A having an increased width with respect to the width of one of the teeth of said first circumferential toothing 81, and a last groove 82D.
  • said thrust means 8' when they are applied to a wing 3 of a weathertight window 10 with sliding opening is the following: when the wing 3 is in said closed position ( figures 7A and 11A ), the handle 99 is in a first position, in which it is preferably arranged vertically, for example with the free operating end 99A preferably facing upward, and said thrust means 8' are in the initial non-operative condition, with the thrust 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 engaged with the corresponding retaining elements 96 and maintain the wing 3 firmly abutting against said sealing strips 5, actuating their sealing effect.
  • the safety locking means 6 are in the locking configuration, in which the lock member 62 is in an extracted position, inserted inside engaging means of the lock member 63 provided on the fixed frame 2 of the weathertight window 1'.
  • the thrust means 8' are arranged so that the first engaging tooth 81A is received in the groove 82A of the first liner toothing 82' and arranged in support against said first abutment tooth 82B, maintaining the first slide 83 in a position in which it exerts a compression on said second spring 87.
  • the user moves conventionally the key inside the keyhole of the cylinder 61, returning back the lock member 62 to the retracted position with respect to the engagement seat 63, thus deactivating the safety locking means 6 ( figure 10B ).
  • the handle also sets said first driving wheel 80' and said second driving wheel 90 into rotation in a concordant direction; thanks to the increased width of said groove 82A, the rotation of said first driving wheel 80' is not initially useful for the movement of said thrust pin 84 but at the same time the second circumferential toothing 91 of said second driving wheel 90 meshes with the second linear toothing 92 of the second slide 93, making it possible to impose a translation in a direction V1 in vertical use to the locking rod 94 and, consequently, to said locking hooks 95 integral to the same, starting the detachment of the latter from the corresponding retaining elements 96.
  • said first engaging tooth 81A reaches said second abutment tooth 82C and, from that moment, further opening rotations of the handle 99 impose a sliding to the first slide 83 along a vertical sliding direction V1 and thus, through said transmission means 85, the movement of said thrust pin 84 along a direction V2 toward the extracted position, in contrast with the action of said first spring 86.
  • said thrust pin 84 is arranged so that the passage between the first position and the second extracted position takes place along a direction parallel to the lying plane of the wing 3, and is configured so that its head surface 84A and the abutment surface 24A of said abutment surface 24 are essentially counter-inclined, so that the thrust S applied also has, in addition to a translation component along a translation direction T1 useful to break the suction of the sealing means 5, a component along a vertical direction T2, such as to allow the lifting of the wing 3 and thus the operation of the sliding means that allow its movement.
  • the last tooth 81B of the first circumferential toothing 81 of the thrust means 8' is rotatably received in the last groove 82D of the first linear toothing 82, which substantially corresponds to the operative condition of maximum thrust, with the thrust pin 84 in the extracted position ( figure 10C ).
  • the handle 99 then freely continues its rotation until it reaches the final open position, where it is preferably arranged vertically, with the free end 99A facing downward ( figures 7B and 11B ).
  • the second operating wheel 90 imposes the sliding of the second slide 93 in the direction opposite to the opening direction ( figure 10E ), retrieving back the locking rod 94 so that the locking hooks 95 integral to it engage the corresponding retaining elements 96 provided on the frame 2.
  • the rotation of the first driving wheel 80' enables the first circumferential toothing 81 to engage with the first linear toothing 82 provided on the first slide 83, causing it to slide along a direction V1 but in the opposite sense, that is, upward, in contrast with the action of the second spring 87.
  • the closing procedure can be completed by activating the safety locking means 6 to move the lock member 62 of the safety lock in the extracted position, so that the lock member is received in the engaging seat 63 provided in the frame 2 ( figure 10G ).
  • a force storage device 30 adapted to store energy resulting from the inertia of the wing during the closing movement, and to provide a thrust in the wing sliding direction T3, contributing in this manner to reducing the force required for the user to open the wing.
  • said force storage device 30 preferably comprises a mounting plate 31, adapted to be connected to the lateral head edge of the wing, on which is mounted an internally threaded bush 32 adapted to be received in the thickness of the same wing.
  • a sleeve 33 wherein are coaxially inserted a first elastic element 34, such as a helical spring advantageously operated by compression, a second elastic element 35, such as a helical spring advantageously operating by traction, and finally a pin 36, provided with a hollow cylindrical body 36A and a flat head 36B, adapted to bear against an abutment element 37 provided on a vertical member 2B of the frame 2 of the watertight window or door 10.
  • a first elastic element 34 such as a helical spring advantageously operated by compression
  • a second elastic element 35 such as a helical spring advantageously operating by traction
  • a pin 36 provided with a hollow cylindrical body 36A and a flat head 36B, adapted to bear against an abutment element 37 provided on a vertical member 2B of the frame 2 of the watertight window or door 10.
  • Said second spring 35 is received within the hollow body 36A of said pin 36 and is connected, with a first end 35A to the bottom of said bush 31, and with the opposite end 36B to the pin 36, near the flattened head 36B of said pin.
  • the first spring 34 is instead arranged externally to the body 36A of the pin 36 in such a way as to impinge in abutment with the first end 34A, against the bottom of the bush 32, and with the opposite end 36B to be pressed by the head of the pin 36.
  • the second spring 35 pulls constantly the pin 36 in the retracted position, while the first spring 34 is adapted to store elastic energy during the closure, to then release it during the opening of the wing 3.
  • FIG. 14A and 14B is shown a weathertight door or window 100 according to a third embodiment of the invention, equipped with a wing 3 with slidable opening provided with sliding and tilting means 7 comprising slidable trolleys 71 pivoting on upper rails 72 and lower accompanying means comprising advantageously a roller 77 running on a guide member 78 and accompanying cams to guide the opening movement of the wing ( figures 15A, 15B , 15C , 16A, 16B and 16C ).
  • Said weathertight window or door 100 includes thrust means 8" (not shown in the figures) mounted on said wing 3, operatively connected to said control member 99 and adapted to drivingly slide a first sliding element 83 along a first sliding direction V1 in vertical use, to integrally move a thrust member 84' between a first position, occupied when said wing 3 is in the closed position, and a second position, in which it interacts with abutment means 24' connected to said fixed frame to give the wing 3 an opening thrust S useful to move it away, that is to separate it, from said frame 2.
  • thrust means 8" (not shown in the figures) mounted on said wing 3, operatively connected to said control member 99 and adapted to drivingly slide a first sliding element 83 along a first sliding direction V1 in vertical use, to integrally move a thrust member 84' between a first position, occupied when said wing 3 is in the closed position, and a second position, in which it interacts with abutment means 24' connected to said fixed frame to give the
  • Said thrust means 8" include first driving means 80' formed essentially by a wheel driven in rotation by said control member 99 and provided with a first circumferential toothing 81 comprising at least a first engaging tooth 81A adapted to cooperate with a corresponding first linear toothing 82' formed on said slidable element 83.
  • the thrust element 84' is formed by an inclined hook ( figures 17A and 17B ), movable integrally with said first slide 83 along a vertical direction V1 and adapted to cooperate with abutment means 24' to provide an opening thrust S to the wing 3 comprising a component along the sliding direction of movement T3 of the wing, and a component along a translation direction T1 essentially horizontal and transversal with respect to the lying plane of the wing 3 in the closed position.
  • said abutment means 24' comprise advantageously an engagement pocket 25 equipped with a frontal guiding slot 25A provided with lateral edges inclined outwardly E to accompany the movement of the wing in the translation direction T1 and with a bottom wall 25B inclined to accompany the movement in the wing 3 in the sliding direction T3 of the wing ( figures 18A and 18B ).
  • the thrust hook 84' mounted integrally to said first slide 83, is thus moved along the same sliding direction V1, leaving progressively the engagement pocket 25 with a movement advantageously guided by the inclined lateral edges of the guiding slot 25A and also cooperating at the same time with the bottom wall 25B ( figures 20A and 20B ) of the pocket 25 so as to apply a thrust S to the wing 3 in the transversal translation direction T1, and also in the direction of sliding movement of the wing T3, thus allowing the user to start without effort the opening movement of the wing 3 away from the frame 2, overcoming the inertia of the wing 3 and breaking the suction created by the action of the sealing means 5.

  • thrust means have been devised for a weathertight wing, adapted to be incorporated in a door or window, that facilitate the user in the action of opening the wing, making it possible to overcome the moment of inertia of the wing and the so-called "vacuum effect".
  • the thrust means according to the present invention are practical and functional, helping the user in the operation of opening the wing to make it absolutely easy and effortless, even if the wing is of appreciable size and weight.
  • the thrust means according to the present invention are rather compact, with limited dimensions, and thus can be incorporated in the frameworks of wings having reduced thicknesses, to the advantage of the glazed surfaces and consequently of the appearance, light transmittance and economy in the quantity of material used in making the wing.
