MOTORIZED SLIDING BARRIER.

DESCRIPTION

The invention relates to a motorized sliding barrier.

AND? known today and more and more? a widespread type of sliding gates, especially for outdoors, known as motorized sliding gates. Generally, a motorized sliding gate comprises a barrier in the form of a frame, or plate, or other similar element, wheels that slide on the ground and guide means for these wheels, for example a rail and at least one support column; generally, the drive means for the barrier are defined near the column.

Normally, the drive means for the barrier include an electric gearmotor associated with a pinion-rack system, where the rack is fixed to a lower part of the barrier and the pinion ? driven by the electric motor-reducer.

This type of motorized sliding gates, while appreciated and widespread, has some aspects that can be improved.

A first drawback linked to known motorized sliding gates? linked to the rack-and-pinion system, since? the translational movement of the rack determines a constant risk that the teeth of the same rack meet a body hooking it and dragging it dangerously; also the pinion-rack coupling ? constantly endangered by the insinuation of dust, dirt and various debris which can adhere to the rack and be dragged by it up to the pinion, with consequent risk of damage.

Another drawback of these motorized sliding gates? given by the necessary presence of the support column, which comprises a group of upper wheels for supporting the barrier; at the base of the support column ? generally positioned the gear motor of the rack and pinion system.

The set defined by the support column and gearmotor ? typically bulky and of low visual impact; in particular, the gearmotor, positioned at ground level, can? create an unexpected and dangerous obstacle for a person walking near it.

Similarly, also the motorized sliding doors, fitted for example inside homes, or in working environments, suffer from similar drawbacks.

In fact, motorized doors require the application of complex hardware, to which the door must be fixed at the top; such hardware must be fixed to the wall in correspondence with the jamb of the crossing gap that the door must close and, even if well masked, they create an encumbrance that the eye cannot see. to neglect.

Task of the present invention ? that of developing a motorized sliding barrier capable of obviating the aforementioned drawbacks and limitations of the prior art.

In particular, a purpose of the invention ? that of developing a motorized sliding barrier that is less bulky than the motorized sliding gates of the known type, as well as? compared to the motorized sliding doors of the known type.

A further purpose of the invention ? to develop a motorized sliding barrier pi? simple to install compared to similar known gates.

The task as well as the aforementioned purposes are achieved by a motorized sliding barrier according to claim 1.

Further characteristics of the motorized sliding barrier according to claim 1 are described in the dependent claims.

- figures 6 and 7 show a variant embodiment of a motorized sliding barrier according to the invention.

With reference to the cited figures, a motorized sliding barrier according to the invention? indicated as a whole with the number 10. This motorized sliding barrier 10 comprises:

- a movable wall 11; in this embodiment the movable wall 11 ? consisting of a mobile gate,

- one or more sliding wheels, for example two sliding wheels 12 and 13, pivoted to this movable wall, or the movable gate 11, and protruding downwards from it, with respect to a normal operating arrangement,

- drive means 14 for the movable wall, configured to translate the movable wall 11, i.e. the movable gate, along a sliding direction X.

The peculiarity of the motorized sliding barrier 10 according to the invention lies in the fact that the motorization means 14 comprise:

- at least one driving wheel, for example a driving wheel 15, constrained to a lower part 11a of said movable wall 11 in such a way as to protrude downwards from the same movable wall 11 for resting on a sliding surface,

- an electric motor 16 configured to drive said at least one driving wheel 15,

- a transmission group 17 configured for the transmission of power from said electric motor 16 to said driving wheel 15,

- power supply means for the electric motor 16.

Said at least one driving wheel 15, the electric motor 16 and the transmission unit 17 are positioned on board said movable wall 11. In particular, in the present embodiment, said at least one driving wheel 15, the electric motor 16 and the transmission 17 are arranged inside said lower part 11a of the movable wall 11.

In the present embodiment of the invention, the power supply means comprise at least one battery, for example a battery 18, positioned on board said movable wall 11 and connected to the electric motor 16.

Such battery 18 ? to be understood to be of type in s? known, rechargeable or non-rechargeable.

It is understood that the power supply means can also be of another type, for example they can be defined by a power supply system by means of a sliding contact between a conductive strip defined on the surface on which the motorized sliding gate 10 slides and a contact appendage protruding from the lower part 11a of the movable wall 11.

By way of non-limiting example of the invention, the transmission unit 17 comprises a driving gear 19, driven by said electric motor 16, and a driven gear 20, fixed to said driving wheel 15 and coaxial therewith.

The driving wheel 15 ? positioned with its axis of rotation Z1 that ? horizontal.

In particular, the electric motor 16 ? arranged with a vertical axis Y. The transmission group 17 also comprises a mechanism for transmitting the rotation between non-parallel axes 24 configured to transmit the rotation from said vertical axis Y to a horizontal axis Z2 which ? of rotation for said drive gear 19; this mechanism can? be constituted, for example, by a coupling between a gear and a worm, to be understood as a type in itself? known.

As mentioned above, the motorized sliding gate 10 comprises two sliding wheels 12 and 13, a first sliding wheel 12 being arranged in front of said driving wheel 15 and a second sliding wheel 13 being arranged behind said driving wheel 15, said sliding elements 12, 13 being arranged inside said lower part 11a of the movable wall 11.

Preferably, the driving wheel 15 ? positioned at the center of gravity of the mobile wall 11.

The presence of two sliding wheels 12 and 13 positioned as described above allows the movable wall 11 to support itself in a balanced way, ie preventing the movable wall 11 from tilting forward or backward with respect to the direction X of advancement.

Alternatively, the movable wall 11 can comprising two driving wheels, correspondingly motorized, and spaced so as to support the movable wall 11 in a balanced way even in the absence of sliding wheels.
