Description

"MOTORIZATION APPARATUS FOR A SECTIONAL WINDOW AND SECTIONAL WINDOW WITH SUCH MOTORIZATION APPARATUS"

FIELD OF APPLICATION

The present invention relates to an apparatus for the motorization of a sectional frame, such as a door, a door, a gate, a roller shutter or the like, as well as to the relative frames provided with the apparatus. Here and in the following of the description, sectional doors and windows are meant those composed of several sections, or slats, arranged parallel to each other and hinged longitudinally to each other to form panels which, in closed position, are arranged on a vertical plane, and in a open are arranged on a different plane from the first, usually orthogonal to the closing one. To pass from one to the other of the closed / open positions, each section o is able to incline locally and temporarily in the area where the two planes meet. Each section according to the present invention has longitudinal edges shaped so that each of them is mated to the corresponding one of the adjacent module.

STATE OF THE TECHNIQUE

Sectional doors and windows of the type previously identified are known, and in particular the partially vertical ones, i.e. doors and windows in which the stroke of the sections to pass from the closed position to the open position provides a vertical, or substantially vertical, section for sliding the sections, not only in correspondence of the opening, but also for a section higher than the opening, along the wall. This solution finds particular, but not exclusive application in industrial warehouses where the floors reach heights of a few meters above the normal openings provided.

It is also known to provide specific motorization devices for the window frame, in which two or more tie cables, with one of their first ends, are fixed to a lateral portion to a base section of the window frame and, with the other end, are tied to a relative pulley keyed on a winding shaft. The winding shaft is possibly controlled to rotate by means of a gearmotor fixed directly or indirectly to this shaft.

This known solution has various drawbacks, especially as regards the movement of the window frame when closing.

In fact, the cables, by their nature, are flexible and therefore cannot bring a thrust on the sections of the window frame which determine the movement spur necessary for closing. For this reason, it is a system of counter cables to determine the starting point of movement of the sectional frame.

This solution is particularly complex and has long assembly and installation times, as well as an increase in the overall costs of construction and management of the sectional frame.

Furthermore, this solution can present drawbacks, especially in the case in which an accidental stop of the sliding of the sections in the guides occurs.

In this case, in fact, the motor, continuing to turn, can cause an over-unwinding of the cable, with consequent derailing of the cable and subsequent complex phases of extraordinary maintenance.

Both for this reason and to ensure safety, and therefore the lifting of the window, in the event of accidental crushing of materials or personnel passing through the passage, the motor is to be controlled by complex auxiliary systems for feedback of the actual movement. of the sectional window.

This known solution entails consequent increases in costs and in the management complexity of the mechanization apparatus.

An object of the present invention is to provide a movement apparatus for a sectional frame, in particular a sectional frame of the partially vertical type, which is simple and inexpensive to manufacture and which allows to obviate the drawbacks of the known art without requiring of auxiliary feedback systems for the actual movement of the sectional frame.

A further object of the present invention is to provide a sectional frame, in particular a sectional frame of the partially vertical type, which is simple and inexpensive to make and which obviates the drawbacks of the known art without requiring auxiliary feedback systems for the actual handling of the sectional frame.

In order to obviate the drawbacks of the known art and to obtain these and further objects and advantages, the Applicant has studied, tested and implemented the present invention.

EXPOSURE OF THE FOUND

The present invention is expressed and characterized in the independent claims.

The dependent claims disclose other characteristics of the present invention or variants of the main solution idea.

In accordance with the aforementioned purposes, a motorization apparatus according to the present invention is applied for the automated movement of a sectional frame comprising a plurality of sections, or slats, hinged together, and mounted sliding relative to a guide frame, fixed at least partly to a building structure.

The apparatus according to the present invention comprises a motor member adapted to move the sectional frame between a first closing position of an opening of the building structure, in which the sections lie on a first, substantially vertical plane, and a second opening position of the passage, in which the sections lie on a second plane substantially inclined to the first floor.

According to a characteristic aspect of the present invention, the drive apparatus comprises a kinematic connecting member, which is at least partially rigid and is, on the one hand, jointed to the drive member and, on the other hand, act to be jointed to the sectional frame.

The motorization apparatus also comprises a guide structure on which the motor member is slidably mounted.

In this way, the sliding of the motor member on the guide structure determines, in a first direction, a pulling action on the sectional frame by the kinematic connecting element so as to bring the sectional frame from the first closing position to the second opening position and, in a second direction, a pushing action on the sectional frame by the kinematic connecting member, so as to bring the sectional frame from the second opening position to the first closing position.

With the present invention, by exploiting the at least partial rigidity of the kinematic connecting member, the sectional door or window can be pushed towards the closed position, unlike known solutions, in which complex counter-cable systems are used, that is the weight of the window or door is used to determine the necessary starting point.

Furthermore, being connected by means of an at least partially rigid kinematic member, the motor member is directly affected by any accidental stops of the sliding of the sections in the guides.

This advantage makes it possible to detect any accidental stopping of the movement of the sectional frame directly from the variation in power absorbed by the motor. This has the advantage of better electronic management of this type of emergency, substantially without the need for auxiliary feedback systems for the effective movement of the sectional frame.

With the solution according to the present invention there is a reduction in the costs of both construction and management of the handling apparatus. According to a variant, the kinematic connecting member comprises two or more lever elements articulated to each other, in which a first of these lever elements is jointed to the motor member and a last of these lever elements is to be bound to the sectional window.

In this way, the variation of inclination of the sectional frame between the first closing position and the second opening position is followed with greater precision.

This variant solution is particularly, but not exclusively, advantageous in the application to partially vertical sectional doors and windows, in which to pass from the closed position to the open position a substantially vertical sliding section is provided beyond the opening defined by the opening.

In fact, this type of solution makes it possible to use an at least partially rigid kinematic member for lifting the sectional frame, overcoming any dead lifting point that would be defined between the motor and the frame, when the latter slides in the vertical section beyond the opening. of the passage.

According to another variant, the kinematic member comprises a chain, or catenary, or other solution such as to ensure sufficient rigidity for the thrust transmission of the movement imparted by the motor member to the sectional frame.

According to a variant, the guide structure is fixed to a portion of the frame of the sectional window.

This variant solution allows to equip an already existing sectional window or door with the motorization apparatus according to the present invention.

According to another variant, rapid fastening means of the guide structure to the frame of the window or door are provided, which have a first interlocking element configured in a manner coordinated with the typical conformation of the frame, and a second interlocking element configured in a coordinated manner with the conformation. of the guide structure to keep it associated with the frame in a given operating condition.

With this variant solution, the motorization apparatus according to the present invention can be installed quickly and economically even on already existing sectional doors and windows.

According to another variant, the kinematic connecting member is adapted to be constrained to a lateral portion of the sectional frame, so as to exploit the frame of the latter as a guide during movement.

DESCRIPTION OF A PREFERENTIAL FORM OF

REALIZATION

With reference to the attached figures, an apparatus 10 is shown as a whole for the motorization of a sectional frame 11, normally used to selectively close an opening obtained in a building wall.

The sectional door or window 11 comprises a plurality of sections 12 hinged together and mounted slidingly with respect to a guide frame 13, fixed at least in part to the building wall, near the opening.

In particular, the guide frame 13 comprises a vertical portion 15, a horizontal portion 16 and a connecting portion 17.

The vertical portion 15 comprises two substantially straight guide profiles arranged laterally to the opening, which are, on the one hand, resting on the ground and, on the other hand, arranged to support a balancing mechanism 18, of the known type, for example , from the Italian patent application IT-UD2009A000089 in the name of the Applicant.

The horizontal portion 16 comprises two substantially rectilinear guide profiles arranged separate from each other at the same distance as the profiles of the vertical portion 15. The two profiles of the horizontal portion 16 are substantially orthogonal to the two profiles of the vertical portion 15.

The connecting portion 17 comprises two curved profiles arranged for structural and functional connection with the profiles of the vertical portion 15 and with the respective profiles of the horizontal position 16.

Each section 12 comprises respective sliding carriages 19, which are fixed along respective lateral portions of the section 12 itself, and are provided with wheels arranged to slide by rolling inside the profiles of the vertical portion 15, of the horizontal portion 16 and of the fitting 17.

In this way, the sections 12 can move by sliding with respect to the vertical portion 15, the horizontal portion 16 and the connecting portion 17, so that they can be selectively arranged between a first closing position of the opening, in which they lie on a plane substantially vertical "V", coherently with the vertical portion 15, and a second opening position of the passage, in which they lie on a substantially horizontal plane "0", coherently with the horizontal portion 16.

In this case, the sectional frame 11 is of the partially vertical type, i.e. a vertical run of the sections is envisaged in addition to the span defined by the opening.

The apparatus 10 according to the present invention comprises a guide structure 20 mounted on one of the two guide profiles of the horizontal portion 16 of the frame 13, a motor 21 slidably mounted on the guide structure 20, and a kinematic mechanism 22 which connects the motor 21 to one of the sliding carriages 19 of the sectional frame 11.

The guide structure 20 comprises a section bar with a substantially "C" -shaped cross section, and inside which the sliding members of the motor 21 are arranged, such as a chain or others, of a traditional type and not described in detail.

As illustrated in figs. 2, 3 and 4, the mounting of the guide structure 20 on the guide profile of the horizontal portion 16 is carried out by means of a plurality of fixing brackets 23.

Each fixing bracket 23 is obtained by bending a sheet metal, so as to define an interlocking plug 25 and an interlocking seat 26.

The interlocking block 25 has such a conformation as to be inserted passing through corresponding slots 27, which are typically provided along the profile of the horizontal portion 16.

In particular, the interlocking block 25 comprises two fins 29, which protrude from the profile of the horizontal portion 16, in assembled condition, and are able to be folded with respect to the rest of the fixing bracket 23, to prevent accidental release of the block slot 25 from the respective slot 27.

The interlocking seat 26 is substantially "C" shaped and houses the guide structure 20 inside it, in a given operating condition.

Advantageously, screws or other locking elements can be provided to consolidate the coupling of the guide structure 20 inside the interlocking seat 26.

The motor 21 is of the towing type and slides linearly with respect to the guide structure 20, so the sections 12 have to be moved between the first and second position.

The kinematic mechanism 22 comprises a plurality of levers 30, in this case five, articulated to each other, in which the first lever 30 is hinged to the motor 21, while the last lever 30 is hinged to a relative sliding carriage 19.

In this case, a sliding wheel 31 is provided at each point of articulation between the levers 30, which is arranged to slide inside the profiles of the horizontal portion 16, of the connecting portion 17 and of the vertical portion 15, so that the movement of the kinematic mechanism 22 is guided in the same way as the movement of the sections 12.

Therefore, a traction or thrust movement of the motor 21 is transmitted by the kinematic mechanism 22 directly on the section 12 of the sectional frame 11, establishing a rigid and at the same time articulated mechanical connection between the motor 21 and the sectional frame 12.

In this case, the motor 21 is associated with electronic elements, of a known type and not illustrated in the drawings, such as an amperometric limiter or the like, capable of detecting the power absorbed by the motor 21 and thus identifying any accidental stops or slowdowns of the sliding. of sections 12.

Advantageously, in the event that any accidental stopping or slowing down of the sliding of the sections 12 is detected, a stop or an inversion of the movement imparted to the sections 12 themselves is commanded, so as to avoid possible damage to people and structures that are in the range of action of the sectional window 11.

It is clear that modifications and / or additions of parts can be made to the motorization apparatus 10 and to the sectional frame 11 described up to now, without thereby departing from the scope of the present invention.

For example, it falls within the scope of the present invention to provide that the kinematic mechanism 22 comprises a single lever 30 constrained, on one side, to the motor 21 and, on the other side, to the section 12 of the sectional frame 11.

It also comes within the scope of the present invention to provide that the vertical portion 15 and the horizontal portion 16 are inclined to each other and not necessarily orthogonal.

It is also clear that, although the invention has been described with reference to some specific examples, a person skilled in the art will be able to realize other equivalent forms of motorization apparatus for a sectional frame and sectional frame with such motorisation apparatus, having the characteristics expressed in the claims and therefore all falling within the scope of protection defined by them.
