DETAILED DESCRIPTION OF SOME PREFERRED EMBODIMENTS

(18) With reference to the attached figures, herein described is a movement system 1 for a liftable slidable leaf A of a slidable lifting door or door-window D.

(19) In particular, FIGS. 1A to 7 and 13A refer to a manual version of the movement system 1, FIGS. 14 to 15D and 21A to 21C refer to an electric version of the movement system 1, while FIGS. 8A to 12C and 16A to 20C refer to both the manual and electric versions of the movement system 1.

(20) The slidable lifting door or door-window D may include at least one slidable leaf A and a fixed or slidable leaf F in a stationary support structure, such as for example a wall facing a floor F.

(21) It is clear that although in the description outlined hereinafter reference will be made to a stationary support structure in the form of a wall, other types of stationary support structures may be considered without departing from the scope of protection of the attached claims.

(22) Preferably, the leaves A and AF may be suitable to be anchored to a frame T which can be fixed to the same stationary support structure.

(23) In a per se known manner, the leaf A may comprise an insulated glazing inserted into a pair of uprights M2 and M2 and two crosspieces T2 and T2, while the frame T may include a pair of uprights M1 and M1 and a crosspiece T1.

(24) The leaf A may include insulating means, for example insulating elements in the form of gaskets of the per se known type, positioned along the perimeter of the same leaf A.

(25) In particular, the insulating means may include the insulating elements G which can be arranged facing the floor F.

(26) Suitably, the insulating elements G will be compressed when the leaf A rests against the floor F so as to ensure an airtight and/or soundproof and/or watertight sealing, thermally and/or acoustically and/or hydraulically insulating the internal environment from the external environment.

(27) Therefore, the system 1 may move the leaf A between a locked lowered closed position, hereinafter identified with locked position and for example shown in FIGS. 1A and 21A, in which the insulating elements G are compressed against the floor F so as to prevent the sliding of the leaf A, an unlocked raised closed position, hereinafter simply identified with unlocked position and for example shown in FIGS. 1B and 21B, and one or more open positions, for example shown in FIGS. 1C and 21C.

(28) In particular, the leaf A may freely slide between the unlocked and open positions. Described below are two versions of the movement system 1, that is a manual version and an electric version.

(29) Both versions may include a guide rail 10 which can be anchored to the frame T which extends along an axis X, which may be substantially horizontal.

(30) In particular, the rail 10 may be positioned on the upper part of the frame T, for example on the crosspiece T1.

(31) Therefore, the rail 10 may be arranged facing the crosspiece T2 of the leaf A.

(32) Furthermore, the system 1 may include sliding means 11, for example a carriage, which slide along the rail 10 to allow the translation of the leaf A along the leaf A.

(33) Furthermore, it is clear that the sliding means 11, as particularly shown in FIG. 12A, may include two or more carriages rigidly connected to each other for example using a rod 110, which slide along the rail 10 in an integrally joined fashion. In this case, the movement of one of the carriages will cause the movement even of the others connected thereto.

(34) Although in the description hereinafter the sliding means will be in the form of a carriage 11, it is however clear that the sliding means may be other types without departing from the scope of protection of the attached claims.

(35) Preferably, the system 1 may include movement means 30 of the leaf A to move it between the locked position and the unlocked position.

(36) The movement means 30 and the carriage 11 may therefore be connected so that the carriage 11 supports the leaf A during the sliding once lifted, as explained in greater detail below.

(37) Suitably, the system 1 may include actuator means 20 which can be engaged with the movement means 30 to move the leaf A between the locked position and the unlocked position.

(38) Specifically, when the leaf A is in open position or during the sliding, the actuator means 20 and the movement means 30 will not be engaged to each other.

(39) Preferably, the movement means 30 may include means for lifting and lowering the leaf A.

(40) In particular, the lifting and lowering means 40 may have a first portion integrally joined with the leaf A and a second portion integrally joined with the carriage 11. The first portion is part of leaf A or a structure attached thereto, and the second portion is part of sliding means 11.

(41) Basically, the control of the actuator means 20 by the user will cause the movement of the movement means 30 as well as the relative movement of the first and second portions.

(42) In this manner the user may control the movement of the leaf A between a first operative position corresponding to the locked position of the leaf A and a second operative position corresponding to the unlocked position of the leaf A.

(43) In a first configuration particularly shown in FIGS. 8A and 8B, the lifting and lowering means 40 may comprise an interface element 60, for example in the form of a square, integrally joined with the leaf A.

(44) Although in the description hereinafter the interface element 60 will be identified with a square 60, the interface element may also be of any other type without departing from the scope of protection of the attached claims.

(45) In addition, the carriage 11 may include an upper portion 11 with wheels 1100 slidable on the rail 10 in a per se known manner.

(46) Furthermore, the carriage 11 may include a lower portion 11 with a pair of brackets 110 and 110 facing each other.

(47) Preferably, the brackets 110 and 110 and the upper portion 11 will define a U-shaped housing.

(48) Therefore, it is clear that the brackets 110 and 110 may be sufficiently spaced apart for the insertion of the aforementioned square 60 between them, in particular in the U-shaped housing.

(49) As a matter of fact, the brackets 110 and 110 may guide the sliding of the square 60 during the sliding and lowering of the leaf A.

(50) Suitably, the portions 11 and 11 will be coupled to each other, for example by means of shape coupling.

(51) In addition, the brackets 110 and 110 may include a pair of through holes faced to which there may be pivoted a slider 43.

(52) Preferably, the square 60 may include a slot 61 with two inclined zones 63 and 47, preferably consecutive.

(53) Therefore, it is clear that the first portion of the lifting and lowering means 40 is integrally joined with the leaf A, as well as the zone of the slot 61 involved in lifting and lowering the leaf A.

(54) In particular, the zones 63 and 47 may have a different inclination so that they are mutually incident and with respect to the axis X.

(55) However, it is clear that the inclined zones 63 and 47 they may not be consecutive, that is there may be a zone interposed between them, without departing from the scope of protection of the attached claims.

(56) On the other hand, the lifting and lowering means 40 may include the aforementioned slider 43 slidable in the zone 47.

(57) In this manner, the slider 43 may define the portion 48.

(58) In particular, the linear movement of the slider 43, that is of the portion 48, along an axis X parallel to the axis X in a determined direction may allow the movement of the leaf A from the locked position to the unlocked position, while the movement of the slider 43 in the opposite direction will allow the movement of the leaf A from the unlocked position to the locked position.

(59) As a matter of fact, the constraining reaction developed by the interaction between the slider 43 and the zone 47 will cause the lifting of the leaf A.

(60) In a second configuration particularly shown in FIGS. 9a and 9B, the lifting and lowering means 40 may comprise a pair of inclined planes 57 and 59 respectively including the first portion and the second portion.

(61) More particularly, the inclined planes 57 and 59 may be constrained to each other in a per se known manner so that the movement of one causes the relative movement of the first and second portions.

(62) In a third and fourth configuration particularly shown in FIGS. 10A to 11B, the lifting and lowering means 40 may include two longitudinal elements 58 and 59 respectively integrally joined with the leaf A and with the sliding means 11.

(63) Therefore, the element 58 may include the first portion while the element 59 may include the second portion.

(64) In this case, the lifting and lowering means 40 may include one or more levers 45 or cams 46 constraining the two elements 58 and 59.

(65) Specifically, the levers 45 and the cams 46 may be pivoted at the elements 59 and they may rotate around an axis perpendicular to the axis X.

(66) In particular, the linear movement of the first portion along the axis X will cause the rotation of the levers 45 or of the cams 46 around the aforementioned axis perpendicular to the axis X, as well as the lifting of the leaf A.

(67) Even in this case, the rotation of the levers 45 or cams 46 in clockwise or anti-clockwise direction will allow the movement of the leaf A from the unlocked position to the locked position and vice versa at a rotation in the opposite direction.

(68) Preferably, the system 1 may include safety means 31 which may act on the movement means 30 to lock the leaf A when it reaches the unlocked position, so as to counter the return thereof to the locked position under the thrust of its weight.

(69) Specifically, the safety means 31 may act on the first and second portions so as to lock them in the second operative position.

(70) For example, in the first configuration, the interaction between the zone 63 and the slider 43 will generate a force such to oppose the return of the first and second portions to the first operative position.

(71) In addition, the square 60 may include further safety means 64, for example longitudinal slots with an inclination defining an incident direction with respect to the extension of the zone 47.

(72) On the other hand, in the second, third and fourth configuration, the first and second portions may include a constraint suitable to lock them in the second operative position.

(73) According to an aspect of the invention, the system 1 may include a guide mechanism 80.

(74) In particular, the guide mechanism 80 will allow to prevent possible oscillations of the leaf A for example under the thrust of the wind or a sudden movement thereof, as well as for leaves A with particularly large dimensions.

(75) In addition, the guide mechanism 80 may also serve as an anti-break-in mechanism as shown below.

(76) Preferably, the guide mechanism 80 may include a magnetic dowel 81 which can be insertedfor example in a dropping fashionalong an axis Z perpendicular to the axis X, as well as concealably in a special housing 82 positioned in a support body 83 in turn positioned at the floor F, preferably flush.

(77) In this manner, the dowel 81 may be easy to remove to allow the cleaning thereof.

(78) Preferably, the dowel 81 may have a longitudinal hollow body 81, for example cylindrical, containing a magnet 81 and a head 810.

(79) The head 810 may have a cross-section with greater extension with respect to the cross-section of the body 81.

(80) This means that the head 810 may have a protruding edge 810.

(81) On the other hand, the mechanism 80 may include an abutment element 84 for the magnetic dowel 81.

(82) The abutment element 84 may include a support 85 flush-inserted into a hollow zone B1 of the lower edge B of the leaf A, preferably at the end facing the upright M1.

(83) The abutment element 84 may further include a metal plate 86 connected to the support 85 by means of a spring 87, facing the dowel 81 and with a movable end 86 protruding from the edge B and an opposite end 86 fixed in the zone B1.

(84) In particular, the spring 87 will allow the plate 86 to move between a position proximal to the support 85 and one distal thereto, respectively at the locked position, wherein the spring is compressed given that the edge B1 rests on the floor F, and at the unlocked or open position.

(85) Specifically, during the sliding of the leaf A from the open position, corresponding to the FIG. 16A, to the unlocked position, corresponding to the FIG. 19, the end 86 and then magnet 81 will be mutually attracted so as to facilitate the exit of the dowel 81 from the housing 82.

(86) The sliding of the leaf A will therefore cause the sliding of the head 810 and of the plate 86, at the end of which the protruding edge 810 will be suitable to be inserted into special guides 88 obtained in the cavity B1 and particularly shown in FIG. 16A.

(87) It is therefore clear that the protruding edge 810 may prevent the dowel 81 from slipping off from the guides 88.

(88) At the locked position, particularly shown in FIG. 20A, the end 86 will therefore be proximal to the support 85, while the dowel 81 may slide along the axis Z so as to be at least partially recessed into the housing 82.

(89) In addition, the guide mechanism 80 may include an optional telescopic guide pivot 90 with a longitudinal body 91, for example cylindrical, having a bottom wall 911 and a head 910 inserted into the guides 88.

(90) The body 91 may be inserted into a housing 92 with a bottom wall 920 and obtained in the support 83 and it may move along an axis parallel to the axis Z under the thrust of a spring 97 connected to the bottom wall 920 and inserted into the body 91 through the bottom wall 911.

(91) As shown in FIGS. 16A to 20A it is clear that during the entire movement of the leaf A, the head 910 will be constantly inserted into the guides 88 under the thrust of the spring 97.

(92) In this manner, such pin 90 will not only act as a guide for the leaf A but also as a security anti-break-in mechanism.

(93) Below is the description of the embodiment of the manual movement system 1, particularly shown in FIGS. 1A to 7.

(94) In such version, the movement means 30 may include the lifting and lowering means 40 of the leaf A.

(95) Furthermore, the movement means 30 may include motion transmission means 50 connected with the actuator means 20 and the lifting and lowering means 40.

(96) In particular, the motion transmission means 50 may be interposed between the actuator means 20 and the lifting and lowering means 40 to transmit to the lifting and lowering means 40 the control imparted by the user through the actuator means 40.

(97) Specifically, the movement means 50 may be connected with the portion 48.

(98) In this manner, the movement of the means 50 will specifically allow the relative movement of the first and second portions between the first and second operative position, as well as the movement of the leaf A between the locked and unlocked position.

(99) Preferably, the actuator means 20 may for example be a handle 23 which can be positioned at the leaf A or at the frame T and which can be gripped by the user.

(100) In a preferred but non-exclusive embodiment, the actuator means 20 may be suitable to be positioned exclusively at the frame T, while the movement means 30 may be suitable to be positioned exclusively on the leaf A.

(101) This will allow to reduce the overall dimensions of the profiles of the leaf A, in particular the exposed parts thereof, allowing a significant decrease in their thickness, as well as the weight of the leaf A to be supported and moved.

(102) Although in the description hereinafter there will be described the actuator means 20 in the form of a handle 23 which can be rotated by a user, it is however clear that they may also be of any other type without departing from the scope of protection of the attached claims.

(103) For example, the actuator means 20 may be in the form of an electric motor 230, shown in FIGS. 13A and 13B, connected with the power supply and an appropriate push-button panel which can be controlled by a user in a per se known manner, wherein the electric motor 230 may be inserted into the frame T, for example at the upright M1, connected with the movement means 50.

(104) According to the preferred embodiment mentioned above, the handle 23 may be positioned on the upright M1 of the frame T so as to face the corresponding upright M2 of the leaf A, as particularly shown in FIG. 1A.

(105) The user may therefore control the lifting of the leaf A by rotating the handle 23 around an axis Y perpendicular to the axis X.

(106) As shown in FIGS. 3A and 3B, the actuator means 20 may include a rack and pinion mechanism having a rack 24 and a pinion 24, the rack and pinion mechanism being inserted into the upright M1.

(107) In addition, as shown in FIGS. 7, 13A, 13B, the actuator means 20 may include a male element 25, which can be engaged with a female element 26 of the motion transmission means 50 when the leaf A is in the locked position.

(108) However, it is clear that also the contrary may occur without departing from the scope of protection of the attached claims.

(109) The male element 25 may for example be a slider integrally joined with the rack and pinion 24, where present.

(110) In this manner, the movement of the rack and pinion 24 will cause the movement of the slider 25.

(111) On the other hand, the movement means 30, specifically the motion transmission means 50, may include striker plate 53 which includes the female element 26, for example an opening obtained therein.

(112) Specifically, the slider 25 may be engaged in the respective opening 26 respectively in a direction parallel to the axis X, along an axis X.

(113) On the other hand, it is clear that should the actuator means 20 instead comprise an electric motor 230, which may be connected to the slider 25, for example by means of a dowel 250 interposed between them, as shown in FIGS. 13A and 13B.

(114) In addition, the motion transmission means 50 may include a pair of closing elements 5000, for example in the form of striker plates, each with a pair of slots 5000 and 5000 with different width.

(115) In particular, the lower slot 5000 may have a width smaller than the slot 5000.

(116) It is clear that the motion transmission means 50 may include one or more closing elements 5000, for example one, two, three, four and so on and so forth, without departing from the scope of protection of the attached claims.

(117) Furthermore, the actuator means 20 may include two sliders, for example in the form of studs, which can be engaged in the respective closing elements 5000.

(118) It is clear that the actuator means 20 may include one or more sliders, one, two, three, four and so on and so forth, which can be engaged with respective closing elements 5000 without departing from the scope of protection of the attached claims.

(119) Specifically, the sliders may be engaged in the slots 5000 at the unlocked position, while the sliders may be engaged in the slots 5000 at the locked position.

(120) Such solution will mechanically lock the leaf A in the locked position, cooperating with the action of the weight force thereof.

(121) Preferably, as shown in FIG. 7, the motion transmission means 50 may therefore includein successiona first closing element 5000, the striker plate 53, a connection rod 54, a second closing element 5000, one or more strips 55, an angular guide 56, a slide 52 and possibly a slidable element 51 connected with the lifting and lowering means 40.

(122) For example, the closing elements 5000, the striker plate 53 and the connection rod 54 may be positioned along the edge of the upright M2, the strips 55 may be positioned at the corner of the leaf A by means of the angular guide 56, while the slide 52 and the slidable element 51 may be positioned along the edge of the crosspiece T2 and be concealed by the crosspiece T1.

(123) In a first example, such slidable element 51 may be a connecting rod, as shown in FIG. 7.

(124) Suitably, the slidable element 51 may include a foot 511 connected with the slide 52 and a head to the slider 43.

(125) Therefore, the foot 511 may be connected with the female element 26 so as to transmit the motion from the actuator means 20 to the slider 43.

(126) From an operative point of view, when the leaf A is in locked position, the user may move the handle 23 by rotating it around the axis Y, for example clockwise, or otherwise by actuating the aforementioned motor 230, so that the slider 25 engaged in the opening 26 drives the leaf A along a direction perpendicular to the axes X and Y, toward the floor.

(127) Such action will cause the translation of the striker plate 53, of the connection rod 54 and of part of the strips 55 along a direction perpendicular to the axis X and the translation of the remaining strips 55, of the slide 52 and of the slidable element 51 along a direction parallel to the leaf A.

(128) Therefore, the slider 43 may slide in the zone 47 to impact against it, move the first portion from the first to the second operative position and allow the unlocking, that is the lifting of the leaf A.

(129) In such position, the safety means 31 may lock the first portion at the second operative position to allow the translation of the leaf A.

(130) On the other hand, the movement described above may also occur on the contrary so as to allow the locking of the leaf A from the unlocked position to the locked position.

(131) Below is the description of the embodiment of the electric movement system 1, particularly shown in FIG. 15A.

(132) In such embodiment, the actuator means 20 may be electric.

(133) Specifically, the actuator means 20 may be exclusively electric.

(134) For example, the actuator means 20 may be suitable to be controlled by a user in wireless mode or there may be provided for a specific circuitry which electrically connects them with an actuation push-button panel, for example positioned at the wall.

(135) To this end, the actuator means 20 may be power-supplied by means of electrical power supply means 70, which may possibly include a buffer battery 73, only when the leaf A is in locked or unlocked position to move it between the one and the other.

(136) In other words, when the leaf A slides between the unlocked position and the open position, the electrical power supply means 70 do not power-supply the actuator means 20.

(137) Suitably, there may be provided for at least one male electrical connector 71 and one female electrical connector 72.

(138) As particularly shown in FIG. 15D, the connectors power-supply the actuator means 20 only when they are in contact.

(139) However, it is clear that also the opposite may be provided for without departing from the scope of protection of the attached claims.

(140) According to a preferred but not exclusive embodiment, such connectors may be of the sliding type.

(141) However, it is clear that other types of electrical connectors may be provided for without departing from the scope of protection of the attached claims.

(142) Suitably, the actuator means 20 may be directly connected with the aforementioned first and second portions.

(143) For example, the actuator means 20 may be a linear actuator 21 positioned above the leaf A.

(144) This will allow to conceal the actuator 21 in the frame T, with ensuing high aesthetic appeal.

(145) In addition, not only the actuator means 20, but also the movement means 30 may be exclusively positioned on the crosspiece T2 of the leaf A.

(146) It is clear that such a solution will allow to reduce the overall dimensions of the movement system 1, and it will also allow to reduce the components thereof, hence simplifying assembly, maintenance and reducing wear.

(147) In any case, the actuator 21 may also be positioned at the upright M2 of the leaf A, as particularly shown in FIG. 14, or of the opposite upright M2, without departing from the scope of protection of the attached claims.

(148) Furthermore, the actuator means 20 may be directly connected to the movement means 30, as well as to the lifting and lowering means 40 described above.

(149) As a matter of fact, as particularly shown in FIG. 15A, in the case of the linear actuator 21 slidable along an axis X parallel to the axis X, it may be connected to the movement means 30 using a stem 510.

(150) Even more specifically, the stem 510 may be connected to the portion 48.

(151) In this manner, the actuation of the linear actuator 21 will cause the relative movement of the first and second portions as well as the movement of the leaf A between the locked and unlocked position.

(152) Also in this case, when the leaf A reaches the unlocked position, the actuator means 20 and the movement means 30 may be electrically disengaged and the leaf A will be free to translate between the unlocked and the open position.

(153) In addition, the linear actuator 21 may ensure that the unlocked position of the leaf A is maintained in safe conditions in a per se known manner.

(154) According to a further aspect of the invention, as particularly shown in FIGS. 1A to 1C and in FIGS. 21A to 21C, there may be provided for a door or door-window D which includes the manual or electric movement system 1 as described above.

(155) The present invention may include various parts and/or similar or identical elements. Unless otherwise specified, similar or identical parts and/or elements will be indicated using a single reference number, it being clear that the described technical characteristics are common to all similar or identical parts and/or elements.

(156) The invention is susceptible to numerous modifications and variants, all falling within the scope of protection of the attached claims. All details can be replaced by other technically equivalent elements, and the materials can be different depending on the needs, without departing from the scope of protection defined by the attached claims.
