Description

Movement apparatus for doors DESCRIPTION This invention relates to a movement apparatus for doors.

More specifically, the movement apparatus according to this invention is applicable to doors of any type which are generally used in the marine and building sector.

More specifically, this invention is intended for the doors of boats, for example yachts.

There are various types of prior art doors which are normally classified on the basis of the type of opening. The most widespread are the traditional and slidable ones.

The traditional doors are those hinged using hinges inside the containment compartment and which open like a book towards the outside and they are characterised by a radius of opening equal to the size of the door. These are generally used on boats with passageways such as to simultaneously allow the passage of persons and the opening of the door.

The sliding doors, generally known as lateral "pantograph" doors, are equipped with a sash which opens outwards whilst remaining parallel to the frame on which it is fixed; this opening is enabled by arms whose movement is similar to that of a pantograph. These doors are widely used on all types of boat, in effect the opening of the door has a reduced size compared to the previous type such as to allow the passage even in narrow passageways, which are typical of boats such as yachts.

The prior art sliding doors can follow opening trajectories which are rectilinear or curvilinear, but not both.

A drawback associated with this type of door is due to the fact that it is necessary for each type of trajectory to make a set of ad hoc guides, which require careful machining and installation, as only with a perfect alignment of the guides can the carriages on which the door slides move simultaneously and allow the correct movement of the door, without blockages during the opening/closing.

Moreover, with this type of guide it is not possible to obtain large depths in relation to the opening of the door and it is often necessary to have to adapt the profile of the supporting wall to aiiow the exit of the door from its containment compartment.

Another drawback relates to the process for making these types of doors; in effect, each trajectory requires relative guides and tracks made ad hoc for that type of application, specifically designed.

The analysis of the prior art also highlighted another important drawback in the production of sliding doors with movement apparatus of known type, which concerns the reduction of the free space defined by the containment compartment due to the dimensions of the apparatus.

Making the doors in question disadvantageously comprises a movement apparatus which is installed at least partly inside the space of the containment compartment of the door.

The end of stroke elements of the carriages and rails of the mechanism which allows the closing and opening of the door are in effect generally fixed in the intrados of the fixed frame, thus reducing the space available for the passage of objects and persons.

In this regard, attention is directed above all to a scenario in which a person who passes through an opening of a door of the type described above might accidentally have an accident or incur an injury caused by a collision with the movement mechanisms, for example with the hinges or the guides where the door Is fixed.

In this context, the technical purpose which forms the basis of this invention is to propose a movement apparatus for doors which overcomes one or more of the above-mentioned drawbacks of the prior art.

In particular, the aim of this invention is to provide a movement apparatus for doors which is structurally simple, versatile, easy to use and to adjust, which allows the door to be opened outwards whilst remaining parallel to the containment compartment.

A further aim of this invention is to propose a movement apparatus for doors which is not fixed inside the containment compartment and which does not require operations for adapting the latter for its installation and/or maintenance.

Advantageously, a movement apparatus for doors is proposed which leaves the containment compartment of the door completely free from any obstructions for the opening/closing of the door.

The technical purpose indicated and the aims specified are substantially achieved by a movement apparatus for doors comprising the technical features described in one or more of the appended claims.

More specifically, this invention provides a movement apparatus for doors comprising guide means for guiding a door from an open configuration, wherein the door is located in a distal position with respect to a compartment containing the door so as to allow access through the containment compartment, to a closed configuration, wherein the door is positioned inside the containment compartment to occlude the passage through the containment compartment.

The guide means are positioned outside to the containment compartment and comprise primary guide means, for guiding the door P along a sliding direction parallel to a main plane of extension in which the door lies from the open configuration to an intermediate configuration, and secondary guide means for guiding the door P along a sliding direction perpendicular to the main plane of extension in which the door lies from the intermediate configuration to the closed configuration and vice versa.

The intermediate configuration is the configuration wherein the door is positioned completely facing the containment compartment.

The dependent claims, incorporated herein for reference, relate to different embodiments of the invention.

Further features and advantages of this invention are more apparent in the detailed description below, with reference to a preferred, non-restricting, embodiment of a movement apparatus for doors as illustrated in the accompanying drawings, in which:

- Figure 1 is a schematic perspective view front of a door equipped with movement apparatus for doors according to this invention, in an open configuration of the door;

- - Figure 2 is a schematic perspective view of Figure 1 in an intermediate configuration of the door;

- - Figure 3 is a schematic perspective view of Figure 1 in a closed configuration of the door;

- Figure 4 is a rear schematic perspective view of Figure 1 ;

- Figure 5 is a schematic perspective view of a portion of Figure 4;

- Figure 6 is a schematic perspective view of a portion of Figure 4 in an intermediate configuration of the door; and

- Figure 7 is a schematic perspective view of a portion of Figure 4 in a closed configuration of the door.

With reference to the accompanying drawings, the numeral 1 denotes in its entirety a movement apparatus for doors P.

Figures 1 to 4 schematically show an externa) structure 100 of a boat. More specifically, a gangway 101 is shown with side panels 102 which defines an outer passageway of the boat, and side walls 103 which divide the outside environment from the inside of the boat.

The side walls 103 are interrupted at openings 104 configured to receive windows or doors.

in the embodiment illustrated in the accompanying drawings, an opening 104 is defined by a containment compartment 2 designed to receive a door P.

The movement apparatus 1 for doors P according to this invention comprises guide means 3 for guiding a door P from an open configuration, illustrated in Figure 1 , to a closed configuration, illustrated in Figure 3. The open configuration in this context means the configuration wherein the door P is located in a distal position with respect to a containment compartment 2 of the door P so as to allow access through the containment compartment 2.

The closed configuration in this context means the configuration wherein the door P is positioned inside the containment compartment 2 to occlude the passage through the containment compartment 2.

The guide means 3 are positioned outside the containment compartment

2. Advantageously, the containment compartment 2 is free from the obstruction of the guide means 3 and guarantees to the user a safe passage through the containment compartment 2.

The internal dimensions of the containment compartment 2 advantageously define the actual gap for the passage of the user.

Preferably) the guide means 3 are positioned below the level of a lower end 2a of the containment compartment 2, as illustrated in Figure 4.

Still more preferably, the guide means 3 are positioned below the treadable surface 105; in this way, they advantageously remain hidden from view and do not limit the arrangement of the inside furnishing.

With reference to Figures 5 to 7, the guide means 3 comprise primary guide means 4 and secondary guide means 5.

The primary guide means 4 are configured for guiding the door P along a sliding direction X parallel to a main plane of extension in which the door P lies from the open configuration to an intermediate configuration,

With reference to Figure 2, the intermediate configuration in this context means the configuration wherein the door P is positioned completely facing the containment compartment 2 and vice versa.

In other words, the intermediate configuration is when the door P is located in a distal position with respect to the containment compartment 2 such that by means of a simple translation perpendicular to the plane in which the containment compartment 2 lies and to the plane in which the door P lies it is possible to position the door P inside the containment compartment 2 so as to make the closed configuration of the door P.

With reference to Figures 5 to 7, preferably the primary guide means 5 comprise first guides 4a, still more preferably two first guides 4a, associated with the door P and slidable on first tracks 4b, yet more preferably two first tracks 4b.

Preferably, the first guides 4a and the first tracks 4b extend along the sliding direction X.

In other words, the primary guide means 4 are designed for making a lateral movement of the door P relative to the side walls 103 of the external structure 100 of the boat.

The guide means 5 are configured for guiding the door P along a sliding direction Y perpendicular to the main plane of extension in which the door P lies from the intermediate configuration to the closed configuration and vice versa.

With reference to Figures 5 to 7, preferably the secondary guide means 5 comprise second guides 5a, still more preferably two second guides 5a, associated with the door P and slidable on second tracks 5b, yet more preferably two second tracks 5b.

Preferably, the second guides 5a and the second tracks 5b extend along the sliding direction Y.

Preferably, the secondary guide means 5 are associated with the primary guide means 4.

In other words, when the primary guide means 4a move causing the first guides 4a to translate along the tracks 4b in direction X, at the same time the second guides 5a and the second tracks 5b also translate.

Advantageously, the combination in the use of the primary guide means 4 with the secondary guide means 5 allows the opening and closing of the door P, moving it simply along two sliding directions perpendicular to each other. By suitably designing and sizing the length and the distance between the first tracks 4b and the second tracks 5b on the basis of the requirements it is possible to obtain any trajectory of the door P inside an ideal plane XY.

Advantageously, thanks to this invention it is possible to also make a movement apparatus 1 for the closing/opening of the door P for very deep containment compartments 2 which are difficult to make with the prior art, on account of the laborious, and sometimes impossible, sizing of the correct radius of curvature of the trajectory to be formed.

Unlike the prior art which comprises curvilinear guide means for moving the door from the containment compartment to the open position alongside the side wall 103, which require ad hoc design and costly machining which cannot be modified subsequently, this invention provides a combination of rectilinear guide means which are easy to make and install and which can be easily modified to allow any trajectory.

In particular, according to a possible embodiment of this invention, the movement apparatus 1 comprises a first s!ide 6 integral with the first guides 4a and with the second tracks 5b and a second slide 7 integral with the second guides 5a and the door P.

In other words, the first slide 6 can only translate along the direction X whilst the second slide 7 can translate along the direction Y independently and along the direction X integral with the first slide 6,

Preferably, the second tracks 5b are arranged on the upper surface 6a of the first slide 6, whilst the first guides 4a are positioned on the lower surface 6b.

Preferably, the door P is connected to the second slide 7 by arms 8, preferably two pairs of arms 8, arranged along a direction parallel to the sliding direction Y.

Preferably, the arms 8 slide, following the movement of the door P, aiong the direction X inside a groove in 103a made in the side wall 103 of the boat.

The movement apparatus 1 according to this invention preferably comprises means for controlling the trajectory 9 of the door P for controlling the passage of the door P from the open configuration to the dosed configuration, through the intermediate configuration, and vice versa. Advantageously, the movement apparatus may be activated manually or automatically.

In that sense, in a possible embodiment of the movement apparatus 1 not illustrated in the drawings, the means for controlling the trajectory 9 of the door P may comprise a motor to control the movement in a motor-driven fashion. The drive unit may be, for example, of the electrical, hydraulic or pneumatic type.

In the embodiment illustrated in the accompanying drawings, the drive unit is, on the other hand, of a manual type and the means for controlling the trajectory 9 of the door P of the movement apparatus 1 comprise a slider 10 integral with the movement of the door P and designed to slide resting on a contact element 11 integral with the first tracks 4b.

Preferably, the first tracks 4b and the contact element 11 are fixed on a plate 106 of the boat and still more preferably the contact element 11 is positioned between the two first tracks 4b.

Preferably, the slider 10 is a roller keyed onto a shaft 10a positioned perpendicularly to the directions X and Y and it is associated with the second slide 7.

The contact element 11 defines the path along which the door P passes from the open configuration to the closed configuration through the intermediate configuration.

Preferably, the contact element 11 having a first portion 11a extending parallel to the sliding direction X and a second portion 11b extending parallel to the direction Y.

Advantageously, the first portion 11a defines the stroke for lateral sliding of the door P along which the door P can move parallel to the side walls 103, while the second portion 11b defines the stroke for inserting/extracting the door P into/from the containment compartment 2. Moreover, preferably the first portion 11a and the second portion 11b of the contact element 11 are connected to each other to form a contact element 11 in the shape of an "L", having a curved stretch at the meeting point of the two portions 11a, 11b (that is, at the intermediate configuration) to give continuity to the contact element 11 on which the slider 10 must rotate along an axis of rotation passing through the shaft 10a.

Advantageously, the open configuration is when the slider 10 is positioned at the free end of the first portion 11a of the contact element 11.

The closed configuration is when the slider 10 is positioned at the free end of the second portion 11b.

The intermediate configuration is at the fastened end of the first portion 11 a and of the second portion 11b.

In order for the user, who is on the gangway 101 and wishes to open a door P which is in the closed configuration and equipped with a movement apparatus 1 for doors according to this invention, to gain access into the boat from the outside, after activating an opening/closing device A of the door P which allows the movement apparatus 1 to be released, it is necessary to:

- push the door P towards the outside in direction Y until reaching the intermediate configuration, moving in this way the second slide 7 (at which are fixed the second guides 5a movable along the second tracks 5b fixed to the first slide 6) which is connected to the door P thanks to the arms 8 and the slider 10 which rotates along the second portion 11b of the contact element 11 ;

- push the door P laterally along a plane parallel to the side wall 103 in direction X until reaching the open configuration, moving in this way the second slide 7 and the slider 10 along the first portion 11a.

The same process may be performed in reverse to close the door P and may also be performed from inside the boat.

As may be noted, the operations to be performed to open/close the door P are very simple.

If the bending of the door P is too high during the opening and closing operations, the guide means 3 of the movement apparatus 1 can comprise supporting guide means, not illustrated in the drawings, positioned outside the containment compartment 2 along the height of the containment compartment 2.

For example, in the embodiment illustrated in the drawings there is a groove 103b inside of which the arms of the supporting guide means, not illustrated in the drawings, can slide.

Advantageously, in this way the door P is more stable during its movement being guided by guide means 3 positioned on several levels.

The movement apparatus 1 described herein is a tool which can be easily used and modified with which it is possible to move a door with an opening outwards which remains parallel to the containment compartment occupying the least possible space and freeing it from any obstructions. At the same time, this invention allows any opening/closing trajectory to be obtained along the plane in which the directions X, Y lie during both design and installation, the movement apparatus 1 being easily adaptable.

This invention achieves the preset aims, overcoming the drawbacks of the prior art.
