Description

Motor-driven sliding door or window

Technical Field

The present invention relates to motor driven sliding doors or windows, and more particularly to sliding doors or windows that are vertically movable.

Background

The sliding type up-down door or window, whether manual or motor-driven, all includes:

-a fixed frame;

-at least one movable sash horizontally slidable with respect to the fixed frame between an open position and a closed position;

-at least one carrier unit associated with the bottom crosspiece of the sash and guided by the horizontal base rails to allow the sash to slide into and out of said open and closed positions;

a control unit comprising a handle (for manual sash) positioned on the sash, which handle firstly allows the sash to be lifted in order to move the lower seal of the sash away from the side of the track, allowing the track to slide to and from the aforementioned open and closed positions, and secondly allows the sash to be lowered to the closed position in order to seal the door or window;

a locking/unlocking or operating element connected to the control unit, which acts between the vertical upright of the sash and the fixed frame, for locking/unlocking the sash in its closed position under the action of the aforementioned handle.

The control (and operation) unit applied to these sliding doors or windows comprises:

-a handle operated by a user;

a movement unit (comprising for example a gear and a rack), to which the handle is connected using a square shaft engaged in a corresponding seat on the movement unit;

a driving rod, which is slidably housed at least in the vertical upright of the movable sash and is connected/controlled by the movement unit so as to move in both directions along the upright.

A part of the above-mentioned locking/unlocking or operating elements is connected to a rod which can be coupled or housed in a striking element or seat located on a vertical post of the fixed frame, to define the sequence of raising the sash in the event of relative release of the sash from the fixed frame and lowering the sash in the event of relative closure on the fixed frame.

The kinematic unit is generally housed in a box-shaped body mounted inside the uprights of the sliding sash, with suitable through seats to allow the kinematic unit to be connected with the handle.

The main difference between a manually sliding door or window (as described above) and a motor-driven door or window is due to the presence of an electrically controlled motor drive applied externally to the uprights of the sash, instead of a handle for manual operation.

The motor drive is provided with a protruding square shaft (defining the motor drive axis by kinematic connection with the motor) which is inserted in the seat of the upright of the sash to connect with the kinematic unit inside the upright.

The motor drive (comprising the outer box-shaped body and the relative connection to the power source) has a control unit which can be programmed to sequentially perform the operations of lifting the sash in the event of relative release of the sash from the fixed frame and lowering the sash in the event of relative closure on the fixed frame due to rotation of the square motor drive shaft.

However, such motor drive systems (which actually use existing control structures) have several disadvantages.

Is rather large and the presence of the external box-shaped body associated with the upright adversely affects the appearance of the structure of the whole sash.

Furthermore, in the event of a power failure or malfunction of the motor drive, in order to operate the sash during opening and closing, the user must perform a complete and laborious removal of the motor drive (and disconnection from the power supply) and then insert the handle for manual operation in the seat of the upright.

This operation is not always possible for a user who in practice must require the intervention of a qualified technician.

It must also be pointed out that this type of motor drive has a high cost.

Disclosure of Invention

It is an object of the present invention to provide a motor driven sliding door or window which overcomes the above mentioned disadvantages of the prior art.

More specifically, it is an object of the present invention to provide a motor-driven sliding door or window which can simplify the structure of a sash, thereby improving the appearance of the sash.

It is another object of the present invention to provide a motor-driven sliding door or window configured to simplify the operation for manually opening and closing the sash in the event of a powered failure of the sash.

These objects are fully achieved by the motor-driven sliding door or window according to the present invention, as characterized in the appended claims.

Detailed Description

Referring to the drawings and in particular to fig. 1, the present invention is directed to a motor-driven sliding door or window, generally designated 100.

The door or window 100 basically comprises: a fixed frame 1, at least one sash 2 movable by at least one but preferably by a pair of sliding carriages 3 and 4, and a control unit 9.

In view of this, the sash 2 is slidable with respect to the fixed frame 1 between a closed position (see fig. 1) and an open position (not shown).

It should be noted that the sash 2 is horizontally slidable along a fixed rail 5 positioned at the bottom of the fixed frame 2 and, in its fully open position (not shown), may (purely by way of example) be superimposed on a fixed sash or a sash that is also movable.

A pair of brackets 3,4 is associated with the bottom crosspiece 2a of the sash 2 and is guided by the rails 5 to allow the sash 2 to slide into and out of the aforementioned open and closed positions.

The door or window 100 comprises a locking/unlocking element 6 (for example a boss) on an operating rod 7, the operating rod 7 sliding along at least one vertical upright 2b of the sash 2.

The locking/unlocking elements 6 interact with respective striker elements 8 positioned on at least the fixed frame 1 so as to lock/unlock the sash 2 between the closed position and the open position and vice versa.

As mentioned above, the door or window 1 comprises a control unit 9 positioned on the sash 2.

The control unit 9 is constituted by a movement unit 10, which movement unit 10 is connected on one side to the operating lever 7 and on the other side to an actuation element for controlling the sliding movement of the operating lever 7 in both directions and along the upright 2b, and allows configurations for opening and closing the sash 2.

The motor-driven door or window 100 solution according to the invention may be of the simple horizontal sliding type or of the "lift-and-drop" type, that is to say, the sash 2 is raised using a control unit and operating levers so as to move the lower seal of the sash 2 away from the side of the rail 5, thus allowing the sash to slide to and from the aforementioned open and closed positions or lowering the sash 2 to the closed position, so as to move the seal to close the door or window 100.

The solution described herein can therefore be used for both types of doors or windows, without limiting the scope of protection.

As shown, the control unit 9 comprises a box-shaped body 12 positioned inside the vertical upright 2b of the sash 2.

The box-shaped body 12 houses a movement unit 10 connected to the operating rod 7 using a drive element 13 and a motor drive element 11 motor-driven by an external energy source, the motor drive element 11 defining an actuation element and being connected to the movement unit 10 for actuating the operating rod 7 by external control.

In other words, the entire control unit (i.e. the moving system and the motor drive elements) is inside the sash and therefore not visible (as shown in fig. 1 to 4).

This makes it possible to improve the appearance of the sash while maintaining a high degree of reliability when the door or window is used.

In view of this (see fig. 2 to 4), the movement unit 10 has an element 14 for connection/disconnection between the driving element 13 and the motor driving element 11, to allow emergency manual movement of the operating rod 7 when required, using the shaft 15 of the handle 16, which shaft 15 can be connected externally to the driving element 13 through a through cavity 17 formed on the vertical upright 2b of the sash 2.

In view of this, the connecting/disconnecting element 14 is movable between a connecting position between the driving element 13 and the motor-driving element 11 and a disconnecting position between the driving element 13 and the motor-driving element 11, the motor-driving element 11 being actuatable, in use, at the entrance of the shaft 15 of the handle 16 (see fig. 5 and 6).

In other words, the solution according to the invention enables the sash to be kept operational (in the event of a power failure) only by means of an external handle (equipped with an operating shaft, with square cross section) which can be inserted into a seat on the sash and by means of which, thanks to the connecting/disconnecting element, can be freely operated on the operating rod like a standard manual sash, bypassing the motor-driven element which cannot be used at this time.

Preferably, the movement unit 10 comprises at least one first gear 18 for transmitting movement between the motor drive element 11 and the drive element 13, and is rotatably constrained inside the box-shaped body 12.

The first gear wheel 18 is rotatably connected with the drive element 13 by means of the connecting/disconnecting element 14.

Preferably, the driving element 13 comprises a bush 19 coaxially coupled inside the first toothed wheel 18 and rotatably constrained to the first toothed wheel 18 by the connecting/disconnecting element 14.

In view of this, the bush 19 has a seat 20 for housing the shaft 15 of the handle 16 (the seat 20 preferably has a square cross section).

The bush 19 has a stem 21 projecting radially from the bush 19 and positioned in a plane parallel to the first gear 18.

Furthermore, the lever 21 is hinged at its free end to the end of an arm 22, which arm 22 is connected to the operating lever 7 and is movable along a plane parallel to the first toothed wheel 18.

In a preferred embodiment, the connecting/disconnecting element 14 comprises at least two

pin units

23,23a, each

pin unit

23,23a being slidably positioned in a respective

radial seat

24,25, said

radial seats

24,25 being formed on both the first gear wheel 18 and the bushing 19 and being positioned coaxially to each other at the connection location between the first gear wheel 18 and the driving element 13.

In view of this, between each

pin unit

23,23a and the first toothed wheel 18 there is an elastic element 26, which elastic element 26 is able to retain the

pin unit

23,23a in the connection position between the bushing 19 and the first toothed wheel 18 and at least allow the retraction of the

respective pin unit

23,23a at the entrance of the shaft 15 of the handle 16, thus releasing the bushing 19 from the first toothed wheel 18.

Preferably, the connecting/disconnecting element 14 comprises at least four

pin units

23,23a, said

pin units

23,23a being equidistant from each other (substantially at right angles to each other to cover 360 °), and housed in respective

radial seats

24 and 25 provided by the first toothed wheel 18 and the bushing 19 (see fig. 5 and 6).

Each

pin unit

23,23a has a respective elastic element 26 interposed between the pin unit and the first gear 18.

Preferably, each pin unit comprises (see fig. 5 and 6) a first pin 23 slidably housed in a respective radial seat 24 of the first gear 18.

The first pins 23 have lower bases 23c in contact with the respective elastic elements 26.

In particular, the lower base 23c is hollow to allow a stable housing of the end of the elastic element 26.

Likewise, the first pin 23 has, at the connection point between the first gear 18 and the drive element 13, a top portion 23d partially housed in a radial seat 25 of the bush 19.

The assembly pin also comprises a second pin 23a slidably housed in a corresponding radial seat 25 of the bush 19.

The second pin 23a has a top portion 23e (in the connection position between the first gear 18 and the driving element 13) projecting from a radial seat 25 of the bush 19 and a lower base portion 23f, said lower base portion 23f of the second pin 23a being in contact with the top portion 23d of the first pin 23 so as to radially push the first pin 23 in the disengagement position between the driving element 13 and the motor-driven element 11, which motor-driven element 11 can be actuated, in use, at the inlet of the shaft 15 of the handle 16.

In other words, when the square shaft is inserted, it cuts off the four tops 23e of the second pin 23a, causing them to retract. This retraction movement allows each top 23e to push the head 23d of the first pin 23, which head 23d is in fact retracted until it is completely housed in the radial seat 24 of the first toothed wheel 18 compressing the elastic element 26.

On the other hand, each second pin 23a is positioned completely inside a respective radial seat 25 of the bush 19, and the opposite lower base 23f is positioned flush between the outer surface of the bush 19 and the inner surface of the first gear 18.

In this way, during the manual rotation of the bush 19 using the handle 16, the lower base 23f of the second pin 23a retains or moves the first pin 23 into the radial seat 24 of the first gear 18.

As can be seen from figures 2 to 4, the motor-driven element 11 housed in the box-shaped body 12 has a drive shaft 27, which drive shaft 27 rotates about its own longitudinal axis and is equipped with a worm 28 engaged on a second gear 29, the second gear 29 being rotatably connected inside the box-shaped body 12.

In view of this, the second gear 29 is engaged on a third idle gear 30, the third idle gear 30 being housed inside the box-shaped body 12 and in turn engaged on the first gear 18 to allow the transmission of the motion (see figure 3).

Such a kinematic mechanism allows the continuous and precise movement of the rod on command of the motor-driven element, even in the presence of heavy sash (in particular for the lifting-sliding type, where the raising and lowering of the sash needs to be performed).

As shown, the box-shaped body 12 is fixed inside the vertical upright 2b of the movable sash 2.

The box-shaped body 12 has a front recess from which at least two coupling elements 31 project for coupling to the operating rod 7.

These coupling elements 31 for coupling to the operating lever 7 are connected to the drive element 13.

The intended object is achieved thanks to such a structure of a motor-driven sliding door or window.

The control unit, including the motor-driven element, is inserted completely inside the sash, so as to achieve a simple and quick assembly of the control system and an aesthetic appearance of the door or window, while maintaining a high level of reliability during use.

In the event of a power failure, the safety of operation is due to the fact that the handle can be simply and safely inserted in the seat located on the upright of the sash, to allow manual actuation of the sash.

In short, only a small hole (conveniently covered by a lid) is visible in the sash, in which the shaft of the handle is applied, if necessary.
