Definitions

  • the object of the present invention is a damping device for a leaf of a lift-and-slide window or door, a relative damping kit and a lift-and-slide window or door.
  • the present invention relates to the movement of a lift-and-slide window or door.
  • the leaf is movable between a lowered position, in which it rests on the lower base of the fitting (frame) in a stationary condition, and a raised position relative to the lower base of the fitting, in which the leaf can slide on the frame, typically from the closed position to the open position.
  • Sliding windows or doors are known in which the leaf is made by a glass panel inserted into a frame, generally made of wood, having both a structural and housing function for the devices and accessories that are necessary for sliding the leaf and locking the leaf in the closed position.
  • windows or doors have a rotatable handle for activating or locking the aforesaid devices for sliding and locking the leaf.
  • the sliding devices comprise carriages joined rigidly consecutively by a connecting device.
  • the carriages are inserted inside a seat made in the lower cross member of the frame of the leaf and are configured to switch between a sliding position and a stopped position so as to permit, respectively lifting or lowering of the leaf and thus opening and closure thereof.
  • the lift-and-slide windows or doors have a wing of considerable dimensions and weight and the inertia thereof can make movement operations between the different operating positions that it can adopt difficult and even dangerous.
  • the difficulty of promptly braking the movement of the leaf occasionally causes episodes of crushing, for example of the hands of the users and/or of animals and/or people who may be in the trajectory of the leaf.
  • Prior art documents CN107435478 and WO 2021198185 refer respectively to an adjustable elastic damper and to an assistance device for closing and opening a lift-and-slide window or door.
  • the technical task of the present invention is to propose a damping device for a leaf of a lift-and-slide window or door, a damping kit for a leaf of a lift-and-slide window or door and a lift-and-slide window or door which are capable of overcoming the drawbacks arising from the prior art.
  • one object of the present invention is to devise a damping device for a leaf of a lift-and-slide window or door and a relative damping kit which permit secure and easy movement of particularly heavy leaves.
  • Another object of the present invention is to propose a damping device, a damping kit and a lift-and-slide window or door that are reliable, tough and durable over time.
  • a damping device for a leaf of a lift-and-slide window or door a relative damping kit and a lift-and-slide window or door comprising the technical features set out in one or more of the appended claims.
  • reference numeral “1" indicates as a whole a damping device for a leaf of a lift-and-slide window or door.
  • the damping device 1 is configured to damp the movement of a leaf "A" in the opening and/or closing direction.
  • the damping device 1 enables the speed of the leaf “A” to be reduced during movement between an open position of the window or door, in which the leaf “A” is distal from an upright of the fixed frame “T” and opens a passage gap and a closed position, in which the leaf “A” is proximal to the upright of the frame and closes the passage gap.
  • the damping device 1 comprises a containment body 2 that is solidly connectable to the leaf "A". Further, a cursor 3 is slidably inserted into the containment body 2 and is reversibly movable between at least a first operating position ( figure 1 ) and a second operating position ( figure 2 ) along a direction substantially parallel to a movement direction "X" of the leaf "A". According to an aspect that will be described better below, the aforesaid first and second operating positions of the cursor 3 are preferably at opposite ends of a sliding channel 8 present on the containment body 2. Preferably, the containment body 2 is connectable to a top portion of the leaf "A".
  • the cursor 3 comprises a first abutting element 4 and a second abutting element 5, each of which is adapted to engage a striker element "R" present on the fixed frame "T".
  • the striker element "R” is positioned on an upper crosspiece of the fixed frame "T".
  • the abutting elements 4, 5 face one another, such that the first abutting element 4 engages the striker element "R” during a passage of the cursor 3 from the second operating position to the first operating position and, further, such that the second abutting element 5 engages the striker element "R” during a passage of the cursor 3 in the opposite direction, i.e. from the first position to the second position.
  • each of the abutting elements 4, 5 is reversibly switchable between a raised condition, in which the abutting element protrudes at least partially from the cursor 3 to abut on the striker element "R" (see abutting element 4 in figure 2 and abutting element 5 in figure 1 ), and a lowered condition, in which the abutting element is at least partially housed inside the cursor 3 to permit relative motion between the cursor 3 and the striker element "R” (see abutting the element 4 in figure 1 and the abutting element 5 in figure 2 ).
  • the cursor 3 can comprise a support body 6 that has a seat 7 that is adapted to house, at least partially, the abutting elements 4, 5 when they are in a lowered condition.
  • first abutting element 4 and the second abutting element 5 can be alternatingly retracted and extracted from the seat 7 of the support body 6.
  • the abutting elements 4, 5 are extracted singly when they have to abut on the striker element "R", whereas they are retracted individually when the relative sliding between the cursor 3 and the striker element "R" has to be permitted.
  • the abutting elements 4, 5 are pivoted on the support body 6 to be reversibly rotatable between the lowered condition and the raised condition.
  • the containment body 2 comprises a sliding channel 8 parallel to the movement direction "X" of the leaf "A” and configured to house the cursor 3.
  • the sliding channel 8 has a cam profile 9 that activates switching of each abutting element 4, 5 from the raised condition to the lowered condition, and vice versa, following the movement of the cursor 3 between the first operating position and the second operating position along the containment body 2.
  • the sliding channel 8 can be delimited transversely by a pair of shoulders.
  • the shoulders further define the aforesaid cam profile 9.
  • the cam profile 9 has a first switching portion 10 and a second switching portion 12 configured to act, respectively, on the first abutting element 4 and second abutting element 5 to promote switching thereof from the raised condition to the lowered condition and vice versa.
  • the damping device 1 can comprise elastic means 14 that is active on the first abutting element 4 and/or on the second abutting element 5 to ensure effective contact thereof against the cam profile 9.
  • the presence of the elastic elements 14 promotes switching of the abutting elements 4, 5 from the lowered condition to the raised condition.
  • the elastic means 14 can comprise one or more springs 15 each of which is operationally interposed between the support body 6 and a respective abutting element 4, 5.
  • the damping device 1 comprises damping means 16 interposed between the containment body 2 and the cursor 3.
  • the damping means 16 acts between the containment body 2 and the cursor 3, at least when the latter moves from the second position to the first position.
  • the damping means 16 enables the speed of the leaf "A” to be reduced during movement thereof between an open position, in which the leaf “A” is distal relative to an upright of the fixed frame "T", and a closed position of the window or door, in which the leaf “A” is proximal to the upright of the fixed frame "T".
  • the damping means 16 can be so configured that the movement of the cursor 3 from the first to the second position results in the activation thereof and a movement of the cursor 3 in the opposite direction results in an at least partial resetting thereof.
  • the damping means 16 confers great safety on the window or door by preventing the leaf "A", because of the inertia due to movement thereof, being able to damage or crush persons or objects arranged along the movement trajectory thereof.
  • the damping means 16 is housed, at least partially, inside the containment body 2.
  • this arrangement confers protection from possible blows and covering by dust, detritus and/or water splashes, for example rain, that could jam the operation of the damping means.
  • the damping means can comprise a pneumatic damper 17.
  • this damper comprises a cylinder 18 fixed to the containment body 2 and a piston 19 fixed to the cursor 3.
  • the piston 19 is slidably movable with reciprocating motion inside the cylindrical body 18 between a maximum insertion position, corresponding to the first position of the cursor 3 in the containment body, and a minimum insertion position, corresponding to the second position of the cursor 3 in the containment body 2.
  • the first abutting element 4 engages the striker element "R” during the passage of the cursor 3 from the second position to the first position, resulting in the movement of the piston 19 from the minimum insertion position to the maximum insertion position.
  • the second abutting element 5 engages the striker element "R” during the passage of the cursor 3 from the first position to the second position, resulting in a movement of the piston from the maximum insertion position to the minimum insertion position.
  • each movement of the cursor 3 from the first to the second position, and vice versa determines a corresponding activation of the piston; this activation causes a slowing of the leaf, when the piston 19 moves in the direction of maximum insertion and is braked by the fluid present inside the cylinder 18.
  • the piston 19 moves in the direction of minimum insertion, the piston 19 is not braked by the fluid present inside the cylinder 18 and thus the movement of the piston serves to reset the damping means.
  • the first abutting element 4 is in the raised condition and engages the striker element "R", determining a passage of the cursor 3 from the second position ( figure 2 ) to the first position ( figure 1 ).
  • the damping means acts between the containment body 2 and the cursor 3 to reduce the movement speed of the leaf "A".
  • the leaf "A” can be further moved from the activation position to the closed position During this movement, the first abutting element 4 is in lowered condition and is not active on the striker element “R” moving solidly with the containment body 2 and permitting relative sliding between the cursor 3 and the striker element "R".
  • the leaf “A” can be moved ( figure 3 ) from the closed position to the activation position.
  • the second abutting element 4 is in raised condition and is active on the striker element "R" to promote a passage of the cursor 3 from the first position ( figure 1 ) to the second position ( figure 2 ).
  • the containment body 2 and the cursor 3 act on the damping means to determine substantially reactivation thereof, for example by determining a passage of the piston 19 from the maximum insertion position to the minimum insertion position.
  • the cam profile 9 activates switching of the second abutting element 5 from the raised condition to the lowered condition.
  • the leaf "A” can be moved further to reach, if it has not already done so, the open position.
  • the second abutting element 5 is in the lowered condition and is not active on the striker element “R” moving solidly with the containment body 2 and permitting relative sliding between the cursor 3 and the striker element "R".
  • the damping device 1 can comprise a further cursor 3 reversibly slidable in the containment body 2 along a direction that is substantially parallel to the movement direction "X" of the leaf "A" between a further first position and a further second position.
  • the further cursor 3 can comprise a further first abutting element 4 and a further second abutting element 5 each adapted to engage a striker element, preferably distinguished from the aforesaid striker element "R”, present on the fixed frame "T".
  • the damping device 1 can comprise further damping means 16 interposed between the containment body 2 and the further cursor 3 to limit the speed of the leaf "A" at least partially.
  • the further damping means 16 can be activatable between the containment body 2 and the further cursor 3 at least during one portion of the passage of the cursor 3 from the first position to the second position.
  • the damping means 16 enables the speed of the leaf "A” to be reduced at least partially at least during the movement of the leaf “A” from the closed position to the open position at least near a further activation position.
  • the damping device 1 can be retrofitted onto a leaf "A" that is already in use.
  • the present invention refers to a damping kit for a leaf "A" of a lift-and-slide window or door, comprising a damping device 1 according to what has been disclosed above and at least one striker element "R” that is connectable to the fixed frame “T” of the window or door and is engageable by the first abutting element 4 and/or by the second abutting element 5 to engage the cursor 3 on the fixed frame "T", in order to determine a relative motion between the containment body 2 and the cursor 3.
  • the present invention refers to a lift-and-slide window or door, comprising a leaf "A” and a fixed frame "T".
  • the leaf “A” moves relative to the fixed frame “T” along a movement direction "X" between a plurality of operating positions comprised between a closed position of the door or window, in which the leaf “A” is proximal to an upright of the fixed frame “T”, and an open position, in which the leaf “A” is distal from the upright of the fixed frame “T” and defines a passage gap.
  • the window or door further comprises a damping device according to what has been disclosed previously and at least one striker element "R” fixed to the fixed frame “T” and engageable by the first abutting element 4 and/or by the second abutting element 5 to engage the cursor 3 on the fixed frame "T", in order to determine a relative motion between the containment body 2 and the cursor 3.
