Description

MOVEMENT ASSEMBLY PARTICULARLY FOR WINDOWS, DOOR LEAVES, SKYLIGHTS, ORIENT ABLE SLATS AND THE LIKE

The present invention relates to a movement assembly particularly for windows, door leaves, skylights, orientable slats and the like.

Buildings for civil and industrial use, such as factory sheds, gyms and the like, are generally provided with windows that are arranged in the upper part of the building or on the roof, and thus are difficult to reach.

For this reason, this type of window is generally provided with an automated system for opening and closing.

Moreover, a device is generally also provided which makes it possible for it to be opened in emergency conditions, such as for example in the event of fire.

The solutions commonly adopted involve designating some of the windows to emergency opening, and some to being opened under conditions of normal use.

Such solution can be adopted only in buildings that are provided with a certain number of windows.

Solutions are known which make it possible for the same window to be opened and closed both in an automated fashion and also under emergency conditions.

Such solutions are particularly complex from the structural point of view and as a consequence are very expensive.

Moreover, in conformance with energy saving regulations in force, buildings must meet preset thermal and acoustic insulation levels.

For this reason, the windows adopted will also have to offer the same thermal and acoustic insulation ratings.

Windows, provided with automated opening, do not always adopt technical solutions that ensure the thermal insulation levels required in order to obtain a specific certification.

The aim of the present invention is to solve the above mentioned problems, by providing a movement assembly particularly for windows, door leaves, skylights, orientable slats and the like, which ensures a high thermal insulation of windows in conformance with the specifications of regulations for energy certification.

Within this aim, an object of the invention is to provide a movement assembly particularly for windows, door leaves, skylights, orientable slats and the like, which is simple and easy to install and maintain.

Another object of the present invention is to provide a movement assembly particularly for windows, door leaves, skylights, orientable slats and the like, which enables opening both under conditions of normal use and under emergency conditions.

Another object of the present invention is to provide a movement assembly particularly for windows, door leaves, skylights, orientable slats and the like, which is low cost, easily and practically implemented and safely applied.

This aim and these objects are all achieved by a movement assembly, particularly for windows, door leaves, skylights, orientable slats and the like, which is characterized in that it comprises a piston which acts on a movable frame of a window with the interposition of at least one bar that can perform a translational motion, said bar being integral with said movable frame, and associable with at least one component chosen from between second means for actuation and elements for locking said movable frame to the corresponding fixed frame.

Further characteristics and advantages of the invention will become better apparent from the description of a preferred, but not exclusive, embodiment of the movement assembly according to the invention, which is illustrated by way of non-limiting example in the accompanying drawings, wherein:

With reference to the figures, the reference numeral 1 generally designates a movement assembly particularly for windows, door leaves, skylights, orientable slats and the like. According to the invention, the movement assembly 1 comprises a piston 2 that acts on a movable frame 3 of a window 4, with the interposition of at least one bar 5 that can perform a translational motion. The piston 2 is actuated exclusively under emergency conditions, detected by a respective sensor which is functionally associated with the piston 2.

The bar 5 can be integral with the movable frame 3 and associable with at least one component chosen from between second means for actuation 6 and elements 7 for locking the movable frame 3 to a corresponding fixed frame 8.

According to the embodiment shown in the accompanying figures, the movable frame 3 is provided with a central upright member 9, on which are arranged the bar 5 and the piston 2 and the second means for actuation 6, if present.

According to a different embodiment, shown in Figures 1 and 2, of particular utility, the second means for actuation 6 can be constituted by a linear actuator 10 coupled to the bar 5 by way of locking means 1 1.

Generally the actuator 10 adopted is an assembly which is constituted by a gear motor which acts on a toothed band for the translational motion thereof.

In the closed configuration of the window 4, a pusher 12 of the actuator 10 (in the example, the end tip of the toothed band) forces the movable frame 3 into abutment on the corresponding fixed frame 8.

In the open configuration, the pusher 12 of the actuator 10 determines the lifting of the movable frame 3 from the fixed frame 8.

In particular, the bar 5 can have a contoured recess 13 which is provided with a port 14 which is open outward for the slideable accommodation of a protrusion 15 which is integral with the pusher 12 of the linear actuator 10.

The movable frame 3 can be provided with a receptacle 16 for accommodating the protrusion 15.

Such contrivance ensures greater stability in the open configuration by preventing it from slipping when it is forced against the movable frame 3.

Moreover, the bar 5 can have at least one hole 17 which is aligned with and proximate to a corresponding slot-like opening 18 of the movable frame 3.

The piston 2 can be provided at an end tip 19 thereof with a pin 20 which is accommodated in the hole 17 and in the slot-like opening 18.

The actuation of the piston 2 determines the forcing and the consequent translational motion of the pin 20 within the slot-like opening 18 with the entrainment of the bar 5 until the alignment of the protrusion 15 with the respective recess 13 and the corresponding egress thereof, through the corresponding port 14, thus allowing the opening of the window 4.

Decoupling the actuator 10 from the movable frame 3 thus enables the opening of the window 4 by means of of the piston 2.

The fixed frame 8 can be provided with a supporting structure 21 on which the piston 2 and the actuator 10 can be hinged, so that they are free to rotate and incline in conformance with the different configuration assumed by the movable frame 3.

In the embodiment shown in the accompanying figures, the supporting structure 21 is arranged below and at the central upright member 9.

According to another embodiment, which is particularly simple and effective, the locking elements 7 can be constituted by a crank 22 which is provided with a projection 23 which can move between a first configuration of interference with a seat 24 of the movable frame 3 to a second, free configuration.

Such embodiment is commonly employed in conventional windows, door leaves, skylights and the like, in combination with a handle, which is adapted to actuate the crank and consequently open/close the window.

According to an embodiment of undoubted practical and applicative interest, the locking elements 7 can be constituted by a crank 22 and by at least one transverse arm 25.

In such solution, the end 26 of the arm 25 is pivoted to the crank 22, and the opposite end 27 is slideable along the movable frame 3 between a first configuration of interference with a seat 28 of the fixed frame 8, and a second, free configuration.

According to the preferred embodiment, shown in the accompanying Figures 9, 10 and 1 1 , the locking elements 7 can be constituted by a crank 22 and by a pair of arms 25.

The crank 22 is provided with a projection 23 which can move between a first configuration of at least partial accommodation in a seat 24 of the movable frame 3, to a second, free configuration.

The pair of arms 25 has the end 26 of the arms 25 pivoted to the crank 22, and the opposite end 27 slideable along the movable frame 3 between a first configuration of interference with a seat 28 of the fixed frame 8, and a second, free configuration.

The closing that can be obtained thanks to such embodiment is particularly efficient in that it ensures that the movable frame 3 is locked to the fixed frame 8 at multiple points thus ensuring optimal mutual alignment even if heavy atmospheric conditions will occur (wind, snow drifts, mechanical tensions induced by thermal deformations).

For such specific implementation architecture, the bar 5 will have, in a portion thereof, at least one hole 17 which is aligned with and proximate to a corresponding slot-like opening 18 of the movable frame 3.

The piston 2 will be provided at an end tip 19 thereof with a pin 20 which is accommodated in the hole 17 and in the slot-like opening 18.

Actuation of the piston 2 will determine the forcing and the consequent translational motion of the pin 20 within the slot-like opening 18 with consequent entrainment of the bar 5, directly or indirectly, against the crank 22 for the movement thereof, and the passage of the projection 23 and of the arms 25, from the first configuration of interference to the second, free configuration.

If a movement assembly 1 is made which is provided with only the projection 23 and/or arms 25, then such component will pass from the first to the second configuration upon actuation of the piston 2.

The possibility is not excluded of making movement assemblies 1 which are provided with a plurality of protrusions 23 and/or a plurality of arms 25 with suitable linkages.

According to an embodiment of undoubted practical and applicative interest, shown in Figures 4 to 7, the bar 5 is associated with the second means for actuation 6 and with the elements 7 for locking the movable frame 3 to the corresponding fixed frame 8.

The simultaneous presence of the second means for actuation 6 and of the locking elements 7 thus makes it possible to obtain an optimal seal of the window 4, in that, in the closed configuration, the movable frame 3 is firmly locked to the fixed frame 8 at multiple points.

In particular, the second means for actuation 6 can be constituted by a linear actuator 10 provided with a pusher 12 which can move.

More specifically, between the bar 5 and the crank 22 at least one box-like body 29 can be interposed, which is open in a downward region, for the free translational motion of the pusher 12 within it.

In this case, actuation of the piston 2 will determine the entrainment of the bar 5 against the body 29 and as a consequence against the crank 22 for the movement thereof and the passage of at least one component chosen from between the projection 23 and the at least one arm 25, from the first configuration of interference to the second, free configuration.

The body 29 thus enables the transmission of the thrust of the bar 5 to the crank 22 without the pusher 12 of the actuator 10 creating an obstacle to the translational motion of the bar 5 itself, and, as a consequence, preventing the passage from the first configuration of interference to the second, free configuration of the arms 25 and of the projection 23. An embodiment is possible in which the piston 2 is constituted by a linear actuation unit (i.e. a device capable of converting the rotary driven motion of a motor to a linear movement of translational motion) with controlled actuation.

The motor, preferably of the electrical type (although the possibility is not ruled out of adopting fluid motors), will in this case be governed by adapted user-accessible commands in order to enable the opening and closing of the installation leaf to be commanded.

The translational motion of the bar 5, which is imposed by the action of the linear actuation unit, will determine the movement of the crank 22 which will ensure the locking/release of the movable frame 3 with respect to the fixed frame 8, by way of mating/separation of the end 27 of the at least one arm 25 with the seat 28 and/or mating/separation of the movable projection 23 with the seat 24.

More specifically, arranged along the edge of one or both of the fixed frame 8 and the movable frame 3 are sealing gaskets 30 for ensuring the substantially watertight closure of the window 4.

The gasket 30, at the corner edges 31 of the fixed frame 8 and of the movable frame 3, has portions which are joined with predefined radii in order to increase the seal.

In this manner, the gasket 30 completely adheres to the edge of the window without undergoing excessive flexion (for example through 90°, as happens at the corner edges 31) which could, over time, determine the early wear thereof, thus making the window 4 lose its seal.

Moreover, the gasket 30 preferably has a transverse cross-section that delimits an inner cavity. In the closed configuration of the window 4, the squeezing of the gasket 30, owing to the reduction of the width of the inner cavity, will increase the seal thereof.

The assembly 1 , according to the invention, can comprise sensors which are functionally associated with the piston 2, for the emergency opening of the window 4 under emergency conditions.

Such sensors can be of the type preferably chosen from among smoke detectors, detectors of variations in heat, fire detectors, detectors of volatile substances of various types and the like.

Such sensors can be functionally associated with a corresponding canister 32 of compressed gas which is connected by way of a duct to the piston 2.

Activation of the sensor will determine, in this case, the opening of the canister 32 and the consequent release of the gas into a cylinder 34 of the piston 2 in order to open the window 4.

The piston 2 can be of a type preferably chosen from among a hydraulic piston, a pneumatic piston, gas springs, actuators in general and the like.

Advantageously, the movement assembly 1 particularly for windows, door leaves, skylights, orientable slats and the like ensures a high thermal insulation of windows in conformance with the specifications of regulations for energy certification.

In fact, the simultaneous presence of the gasket 30, the second means for actuation 6 and the locking elements 7 makes it possible to obtain thermal and acoustic insulation levels that are suitable for obtaining a specific energy certification.

Positively, the movement assembly 1 particularly for windows, door leaves, skylights, orientable slats and the like, according to the invention, ensures an exceptional ease of use.

In fact the operation of the movement assembly 1 is simple and intuitive.

By way of a user interface, for example a keypad or a switch (not shown in the accompanying figures) the user can actuate the movement assembly 1, and in particular the actuator 10, and command the consequent opening or closing of the window 4. Actuation of the actuator 10 determines the egress of the pusher 12 which, acting on the movable frame 3, lifts it, entraining therewith the piston 2 which, being discharged, does not constitute a hindrance to the action of the actuator 10.

Similarly, it is also possible to open the window 4 under emergency conditions, such as for example in the event of fire.

In fact, in the event of fire the sensor is activated, determining the opening of the canister 32 and the consequent release of the gas into the cylinder 34 of the piston 2, in order to open the window 4.

Conveniently, the movement assembly particularly for windows, door leaves, skylights, orientable slats and the like enables opening both under conditions of normal use and under emergency conditions.

The movement assembly 1 , according to the invention, can also be installed on zenithal, vertical, or inclined frames with different inclinations.

In practice it has been found that the movement assembly particularly for windows, door leaves, skylights, orientable slats and the like, according to the invention, fully achieves the intended aim, in that it ensures a high thermal insulation of windows in conformance with the specifications of regulations for energy certification.

The invention, thus conceived, is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims. Moreover, all the details may be substituted by other, technically equivalent elements.
