SUPPORT DEVICE FOR SLIDING DOORS

MOTORIZED

DESCRIPTION

This patent relates to sliding doors and in particular concerns motorized sliding doors.

Sliding doors are normally made up of a panel, which constitutes the door leaf, having two or more carriages sliding on a guide or rail fixed to the wall at the top.

Each carriage normally has two wheels or two pairs of wheels sliding in a seat, or relief, of the guide.

Sliding doors with manual opening and closing also have a handle for their opening.

Sliding doors with motorized opening and closing are usually without handles and are equipped with one or more motors which, with the help of belts or levers, move the door leaf from the open position to the closed position and vice versa.

Appropriate limit switches or sensors stop said motors when the sliding door reaches the completely open or completely closed position.

The lower edge of the sliding door slides inside a guide or guide portion adapted to prevent the translation of the lower edge of the door in a direction orthogonal to the direction of sliding of the door itself. This lower guide can have a U-shaped section, so that the lower edge of the door slides inside, or it can have an inverted T-section, so that the upper end of the guide slides into a lower groove of the door.

Sliding wooden doors usually have an internal frame or honeycomb structure and consequently have a low weight, while sliding glass doors include a glass panel of adequate thickness to withstand normal shocks.

The glass panel of the sliding doors normally comprises two or more glass plates coupled together with the interposition of a transparent plastic film and therefore they are particularly heavy.

Consequently, all the supporting parts of the door must be sized to support the weight of the glass panel and all the weight is supported by the floor both during movement and in the open or closed rest phase.

Sliding glass doors usually include a lower device capable of transferring the weight of the glass door to the floor, to allow easy opening even with very heavy doors. they allow the door to be lifted through a control lever and through a manual push or a motorized system with belts or levers to move the door to the open or closed position.

Basically there are mechanisms or wheel devices, placed in the lower part of the door. which, in the open position but above all in the closed position of the door, allow the door to be placed on the floor.

Such mechanisms or devices are applied to the lower edge of the door. Said mechanisms or devices require a specific installation and in any case need a guided system, always present in the floor, constituting a physical encumbrance as well as a dirt collector.

The subject of the present patent is a support device for motorized sliding doors not having support mechanisms for the floor door

One purpose of the new support device is to have no sliding door support mechanism or device at the bottom edge of the door or in the floor path of the door.

Another purpose of the new support device is to rest the lower edge of the sliding door on the floor when it reaches the end of its travel both in the closed and in the open position.

These and other direct and complementary objects are achieved by the new support device for motorized sliding doors comprising a sliding guide and at least two lowering mechanisms.

The vertical translation mechanisms are designed to lower / raise the door in correspondence with the closed door position. The sliding guide has a generically C-shaped section with at least the extremity of the lower wing folded towards the upper wing and in any case of such shape as to allow a suitable guide to be coupled to motorized roller systems.

Said lower wing and its folded end constitute the sliding path of the wheels of the support carriages of the door panel. Said sliding guide can be of two types, a first case where the guide is continuous and in any case supports all the weight of the door, the up and down movement is given by two motorized systems each applied to each motor block on which The door hangs.

The ascent and descent system allows, by intervening on the arm or vertical position of the wheel, to change its position in height with respect to the block itself, generating the raising or lowering of the door itself.

The door is normally anchored to two motorized systems that generate the opening and closing movement.

In the second case, the profile is interrupted in at least two portions or segments corresponding to the positions of the trolley wheels when the door is in the closed position.

In correspondence with said open portions or segments of said sliding guide said two lowering mechanisms are applied.

Each lowering mechanism comprises a body for fastening to the sliding guide, at least one electromechanical actuator and a translating support element.

The fixing body is suitable for joining each lowering mechanism to the sliding guide and for fixing the electromechanical actuator and the translating support element.

At least a part of said fixing body is adapted to occupy and constitute continuity of the lower wing of an open portion of the sliding guide. The translating support element substantially has a vertical plane shape or section and dimensions such as to occupy and complete the upward-facing end of the lower wing of an open portion of said sliding guide. Said translating support element is hinged or in any case fixed to said fixing body in such a way as to be able to translate or rotate from a position in which it constitutes the continuation and connection of the end facing upwards of said lower wing of the guide rail. sliding, to a position in which it is lowered with respect to the upward-facing end of the lower wing of said sliding guide.

The electromechanical actuator is joined to said fixing body and is able to translate or rotate said translating support element from the raised position, in which it constitutes a connection and continuity of the edge facing upwards of the lower wing of said guide rail. sliding, to the lowered position.

Said electromechanical actuator is controlled and synchronized with the same mechanism that commands and controls the sliding of the support carriages and sliding of the door panel.

Two additional lowering mechanisms or devices are expected to be present at the open position of the door.

Each carriage for supporting and sliding the door panel comprises a structure suitable for fixing to said door panel and at least one wheel able to slide on said upward-facing end of the lower wing of the sliding guide.

Each support and sliding trolley includes at least one electric motor for rotation of the wheels of the trolley itself for advancement.When the door is in motion, each translating support element is raised in continuity and connection with the extremity facing the top of the lower wing of the sliding guide so as to allow the wheels of the support carriages to slide freely along said sliding guide.

When the door reaches the closed position, its translation along the sliding guide is stopped. In this position, the wheels of the carriages are in correspondence with the lowering mechanisms or devices.

At this point, said lowering mechanisms or devices lower the relative translating supporting elements.

This lowering of the translating support elements involves the lowering of the wheels of the trolleys, of the trolleys themselves and consequently of the door panel.

In this way the lower edge of the door panel rests on the ground, unloading its weight directly on the ground while the translating elements prevent the upper edge of the door panel from falling sideways.

Furthermore, the lower edge of the door resting on the floor prevents the door itself from swinging orthogonally to the direction of translation of the door.

The characteristics of the new support device for motorized sliding doors will be better clarified by the following description with reference to the drawing table, attached by way of non-limiting example. In the attached tables a practical embodiment of the invention is presented, by way of non-limiting example.

Figures 1a and 1b show a sliding guide (1) which has a generically C-shaped section with at least the end (1.3) of the lower wing (1.1) folded towards the upper wing (1.2).

Said lower wing (1.1) and its folded end (1.3) constitute the sliding path of the wheels (3.1) of the support carriages (3) of the door panel (4). The sliding mechanisms (3) include the wheels (3.1) and the vertical translation mechanisms (2) adapted to translate the wheels (3.1) with respect to the body (3) with consequent lowering / lifting of the door (4) integral with said body ( 3)

Figure 2 shows an axonometric view of the new support device for motorized sliding doors comprising a sliding guide (1) and at least two lowering mechanisms or devices (2) integral with said guide

Said sliding guide (1) has no said lower wing (1.1) in at least two portions or segments (1a, 1b), subsequently called open portions or segments, corresponding to the positions of the wheels (3.1) of the carriages (3) when the door is in the closed position.

In correspondence with said open portions or segments (1a, 1b) of said sliding guide (1) said two lowering mechanisms or devices (2) are applied, as illustrated in detail in Figure 3c.

Figures 3a and 3b show a lowering device (2) in its two positions.

Each lowering mechanism or device (2) comprises a body (2.1) for fastening to the sliding guide (1), at least one electromechanical actuator and a translating support element (2.2).

The fixing body (2.1) is suitable for joining each lowering mechanism or device (2) to the sliding guide (1) and for fixing the electromechanical actuator and the translating support element (2.2). At least a part of said fixing body (2.1) is able to occupy and constitute continuity of the lower wing (1.1) of an open portion (1a, 1b) of the sliding guide (1).

The translating support element (2.2) has a substantially flat vertical shape or section and dimensions such as to occupy and complete the upward-facing end (1.3) of the lower wing (1.1) of an open section (1a, 1b) of said sliding guide (1).

Said translating element (2.2) is able to translate or rotate from a position in which it constitutes the continuation and connection of the upward-facing end (1.2) of said lower wing (1.1) of the sliding guide (1) as illustrated in Figure 2a, to a position in which it is lowered with respect to the upward-facing end (1.3) of the lower wing (1.1) of said sliding guide (2) as illustrated in Figure 2b.

All the up / down and opening / closing movements are generated by motorized electromechanical systems which, depending on the needs, can be powered by battery, with recharging positions in opening, closing and programmed stops, or continuously powered through a cable connection to the General power supply, or to a mixed system which in any case guarantees a certain number of opening and closing operations even in the absence of electricity.

In both solutions there is a manual system that allows the mechanical lifting of the door / leaf, its opening / closing and its descent.

These are the schematic modalities sufficient for the skilled person to realize the invention, consequently, in concrete application there may be variations without prejudice to the substance of the innovative concept.

Therefore, with reference to the above description and the attached tables, the following claims are expressed.
