Description

DEVICE FOR MANAGING AND / OR DEGONDING AN ASSOCIATED VANTAIL, VANTAIL AND ASSEMBLY METHOD

The invention relates to the field of devices for assisting the installation of leaves. More specifically, the invention relates to a device for hinging and / or disengaging a leaf, said device being intended to be integrated within said leaf. The leaf can, as non-limiting examples, consist of a door or a door window.

A leaf is generally composed of a panel or any equivalent means, to create an opening and / or a temporary closure in a bay or a wall or even a wall. Such a leaf is generally pivotally mounted, as non-limiting examples, on a frame, a door frame, a door frame, a frame, a frame, etc. The cooperation between a leaf and a frame can advantageously be achieved by means of a pivot connection, embodied by way of non-limiting example, by means of one or more hinges.

We will hear, in the rest of the document and in a non-limiting way, by "leaf" the movable part of a door, a window, a door window and / or a shutter, and "gond" a generally but non-limiting metal and / or plastic part serving as support and guide in rotation to a leaf, said hinge consisting of a first part called "female" intended to be fixed on the movable part of a leaf and a second part called "male" intended to be fixed on a frame. Said female part generally comprises a recess provided to receive a rod projecting from said male part. The invention however provides that such male and female parts can be positioned in an inverted manner, said female part being intended to be fixed on a frame and said male part being intended to be fixed on the movable part of a leaf.

Leaves, such as a door or a window, consist of bulky pieces of joinery, difficult to handle, especially during their installation and / or removal, and often very heavy. A door, for example, can be isoplane, that is to say be constituted by two facing fixed on either side of a wooden frame whose core can be alveolar, solid and / or insulating, c that is to say respectively consisting of strips of cardboard or slats of solid wood, wood fiber panels, or a polyurethane foam. A door can also be made of wood, that is to say include one or more amounts and / or cross-members forming a frame and filling panels, said frame and said panels being generally made of solid wood. Certain doors, in particular the entrance doors and windows, may be made, without limitation, of wood, aluminum and / or plastic, such as polyvinyl chloride commonly known as "PVC", and may comprise, in particular variant or in addition to the glazing. Thus, by its structure and / or composition, the weight of a door or window can quickly reach or even exceed eighty kilograms, limiting their maneuverability during installation and / or uninstallation.

Nowadays, the installation and / or the removal of a leaf is usually done manually. then of an installation, an operator maintains in his final position, for example vertically, said leaf then raises the force of his arms to align or bring the male and female parts of each hinge to associate them coaxially. This alignment can become tedious, especially if the leaf comprises a plurality of hinges. Therefore, the operator gets tired during his tests and may be forced to rest said door before attempting a new test. To facilitate the installation and / or removal of the leaf, said operator can let it rest on one of his feet, thus allowing to have a slightly raised leaf to simplify the introduction of the hinges and prevent the operator must bear the weight of the door at arm's length. This makeshift method has many disadvantages, particularly related to the risk taking of the operator. The difficult handling of a leaf can indeed cause the rupture of the phalanges of the foot or joint trauma at the feet of the operator, or create injuries to the back and / or arms.

To preserve their physical health, some operators make crowbars or levers from hammers, screwdrivers and / or any tool near the place of installation and / or removal. The making of such means of curling or unhinging, however, remains very limited and in no way ensures the physical integrity of the operator and / or carpentry.

To overcome its disadvantages, devices adapted to the installation and removal of swing doors have been developed, as described by way of non-limiting examples, in EP1768924 and US6,378,191. Such devices generally comprise a tray, to fit under said door, cooperating with a lever, the latter for lifting said tray under the action of the foot of an operator. Such devices however remain unwieldy. Indeed, the operator must hold the door with both hands in its final position, that is to say vertically, and rotate its pelvis to be able to properly position his foot on said lever. Such a position can be uncomfortable and slow down the installation or removal process. In addition, such devices are complex to manufacture and are expensive to purchase. In addition, for better use, it is preferable to work in pairs, a first operator supporting the door and a second operator operating the lever of said device.

The disadvantages encountered during the installation of a leaf, as described above, are also present when the operator must uninstall the latter. Indeed, an operator must insert a hand in the doorway of the leaf, then lift said leaf by the force of his arms or by means of a third device to disengage said leaf, at the risk of hurting eg back or at the feet, under the weight of the door.

The invention makes it possible to respond particularly effectively to all or some of the disadvantages raised by the known solutions.

Said device being advantageously positioned at elbow height, its operation by the hand of an operator is facilitated. In addition, the weight of the leaf is directly supported by said device, allowing the operator to focus on the alignment of the female part and the male part of the hinges.

Finally, a device according to the invention that can comprise a rolling means, such as a ball or a wheel, makes it possible to move said leaf without effort, in order to move it to the installation location and position it in its position. final position. To this end, the invention relates to a device for hinging and / or disengaging a leaf comprising a pusher element comprising a notched part, an actuator element comprising a notched part and a fixing element, the respective notched parts of said pusher element and said element. actuator cooperating according to a rack-type mechanical connection, so that a rotational movement of the actuating element causes a translational movement of the pusher element, said fixing element being arranged to maintain in contact said notched parts of the pusher element and the actuator element. To ensure easy installation and / or removal of said leaf, the notched portion of the pusher element of a device according to the invention is of sufficient length to cause a displacement of said pusher element by a distance of overflow. at least equal to a height of the hinge pin during the actuation in rotation of the actuator element. According to a preferred but non-limiting embodiment, the pusher element of a device for hinging and / or disengaging a leaf according to the invention may consist of a rod provided with a transverse degree of freedom along its longitudinal axis.

To facilitate the use of a device according to the invention, the actuating element of a device for hinging and / or disengaging a leaf according to the invention may comprise a lever cooperating with a cylindrical head for all or notched part said lever and said cylindrical head forming one and the same physical entity.

As a variant or a complement, a device according to the invention may be actuated by a third lever. According to this advantageous embodiment, the actuator element of said device may comprise a recess for accommodating an end of said third lever.

To facilitate the movement of a leaf comprising a device according to the invention, the pusher element may comprise a rolling means located at one end of said pusher element remote from the fixing element.

According to various embodiments of a device for hinging and / or disengaging a leaf according to the invention, such a rolling means may comprise a ball or a wheel.

FIGS. 3a and 3b show a preferred nonlimiting embodiment of a device for hinging and / or disengaging a leaf according to the invention, respectively in passive configuration and in active configuration. As an example of a preferred but nonlimiting application, the invention will be described through a leaf in the form of a door having a device for hinging and / or disengaging said door on a frame. The invention, however, can not be limited to this single embodiment and could alternatively be transferred to any leaf, such as, for example, a window, a window door or a flap.

Figure 2 shows a perspective view of a preferred embodiment but not limited to a door 20 adapted to include a device 10 for hinging and / or disengaging said door 20 according to the invention. Such a door 20 is advantageously composed of a panel 20c of solid wood, preferably but not limited to cubic, that is to say having six faces or blanks. The invention can not be limited to this type of door or to this single material component of said door. Indeed, a device 10 according to the invention may, in a variant, be integrated with solid or hollow isoplane doors, with solid carved doors comprising uprights, with wooden doors, with wood fiber, with plastic, with metal, etc.

In the rest of the document, we will read:

- "upper face" FS, the face of the mirror door of the ceiling, and parallel to the underside.

In the same way, we will name:

- "median plane" PM, any normal plane to the door 20, which separates a half having the attachment face Fl of a half having the closing face of the door 20, said halves are not necessarily equal;

- "transverse plane" PT, any plane normal to a median plane, which separates the door 20 in a half having the upper face and a half having the lower face FI of the door, said halves are not necessarily equal;

- "longitudinal plane" PL, any plane normal to a median plane and a transverse plane, said halves not necessarily being equal; . Such plans PM, PT, PL are illustrated in lines alternating a point and a dash in Figure 2.

In the same way we will name:

"Transverse axis" means any axis belonging both to a transverse plane and to a median plane; "Longitudinal axis" means any axis belonging both to a longitudinal plane and to a median plane; - "median axis" means any axis belonging both to a median plane and to a longitudinal plane. To be able to include a device 10 for hinging and / or disengaging a door as described later, a door 20 according to the invention comprises a first recess E1 substantially parallel to a longitudinal axis of said door 20 and opening on the underside of said door. Preferably, but not exclusively, such a recess E1 is located near the attachment face FA of said door 20. Such a recess E1 can be created, for example, by means of a reamer, a drill and / or a ripper. In order to facilitate the handling of a device 10 for hugging and / or dislodging according to the invention, the length of said recess E1 may be, preferably but not limitatively, equal to a man's elbow height, ie approximately one meter fifty . Furthermore, the section of such a recess E1 can have any suitable geometric shape, that is to say, preferably but not limitatively square, circular or rectangular.

A door 20 according to the invention further comprises a second recess E2, substantially parallel to a central axis of said door 20 and opening on the attachment face FA of said door. In order to accommodate within them a device for hinging and / or disengaging a door 20 according to the invention, said first recess E1 and said second recess E2 of a door 20 according to the invention are secant, that is, that is, they have a non-empty intersection. Preferably, but not exclusively, such a recess E2 may have a substantially cubic shape, as shown in FIG. 2, or alternatively, in order to ensure a suitable and / or optimal housing of the device for hinging or disengaging the door, in the form of ^λ Τ 'or ^X L', as shown in Figures 3a and 3b.

Preferably, but not exclusively, the recesses E1, E2 of a door 20 according to the invention are advantageously practiced near the attachment face FA, that is to say nearest to the hinge or hinges 17 fixed on said attachment face FA, so that the effort applied by an operator on a device 10 for hinging and / or disengaging a door is reduced and thus the risk of injury to said operator and / or damage to the door 20 be decreased.

FIGS. 3a and 3b show perspective views of a preferred but non-limiting embodiment, respectively in passive and active configurations, of a device 10 for hugging and / or unhinging a door 20 according to the invention comprised within such a door 20.

A device 10 for hinging and / or disengaging said door according to the invention first comprises a pusher element 11 and an actuator element 13 cooperating with said pusher element 11 according to a mechanical connection transforming a rotational movement of the actuator element. 13 in a translational movement of the pusher element 11, for example according to a rack-and-pinion type gear connection.

As non-limiting examples, such a pusher element 11 may consist of a rod or a metal bar of substantially circular or square section. In order to ensure optimal accommodation within a door 20 adapted to a device for hinging and / or disengaging a door 20 according to the invention, such a rod or more generally the pusher element 11 has a length a maximum of substantially equal to that of the recess E1 of the door 20 intended to comprise said device 10 and of section slightly smaller than the section of said recess E1, for example less than one millimeter, in order to allow the pusher element 11 to to lodge and slide in said recess El acting as a guide.

To cooperate with the actuator element 13, said pusher element 11 may be for all or part notched. For example, said pusher element 11 may be for all or part threaded, that is to say comprise a helical groove, or alternatively or in addition, have substantially parallel notches or teeth, such as for a rack. For example, a pusher element 11 in the form of a circular section rod can be hollowed out to create a succession of grooves at a regular distance, thus producing parallel collars or notches. Alternatively, such a circular rod can be planed along its longitudinal axis to create a flat or flat on which can be regularly excavated grooves and thus show notches. When such a rod is of square section, a longitudinal face of said rod can be hollowed to reveal said notches. The invention can not, however, be limited to these examples of embodiment of the pusher element 11 of a device for hinging and / or disengaging a door according to the invention. Any other method or other arrangement showing notches on all or part of the pusher element 11 may be, alternatively or in addition, implemented.

The actuator element 13, meanwhile, may comprise a cylinder for all or notched portion or, alternatively or in addition to a crenellated disk, such as a pinion for example. The invention can not, however, be limited to these only embodiments of the actuator element 13 of a device for hinging and / or disengaging a door according to the invention and could alternatively comprise any other suitable structure. Alternatively or in addition, a device 10 for hinging and / or disengaging a door according to the invention, more particularly the actuating element 13, may comprise a plurality of toothed discs or pinions cooperating with each other, mutually and together to slide the pusher element 11. The presence of a plurality of notched disks or pinions is particularly advantageous, since it allows in particular to increase the force applied to the lever rotating the actuator element or elements and thus to reduce the effort of the user and / or operator. The notched part of the pusher element 11 and the notched part of the actuator element 13 are then mutually arranged to cooperate with one another and operate in a conjugated manner. Such cooperation between the respective notched parts of a pusher element 11 and an actuator element 13 is materialized by a mechanical connection of rack type, so that a rotational movement of the actuator element 13 causes a translational movement. of the pusher element 11. Thus, to ensure optimal cooperation of the pusher elements 11 and actuator 13, the longitudinal axis of the pusher element 11 may be preferably normal to the axis of rotation of the actuator element 13.

Still, to ensure optimal cooperation between the notched portion of the pusher element 11 and the notched portion of the actuator element 13, while preserving the respective degrees of freedom of the pusher element 11 and the actuator element 13 of a device 10 for hinging and / or disengaging a door 20 according to the invention; The last advantageously comprises a fastening element 16. Such a fastening element 16 is advantageously arranged to maintain in contact said notched parts of the pusher element 11 and of the actuating element 13. Said fastening element 16 may, as a nonlimiting example, consist of a part simultaneously and jointly including a portion of the pusher element 11 and a portion of the actuator element 13. Advantageously but not limited to, according to one embodiment of a device 10 for hinge and / or disengage a door according to the invention described in particular in connection with Figure 3a, such a fastening element 16 may consist of a first assembly 16 'can encompass or pregnant dre the notched portion of the pusher element 11, for example in the form of a hollow half-cylinder whose axis of revolution is parallel to the longitudinal axis of said pusher element 11, and a second assembly 16 '' encompassing or embedding the notched portion of the actuator element 13, for example perpendicular to the axis of rotation of said element, as shown in FIG. 3a. To keep in contact the respective toothed parts of the pusher element 11 and of the actuator element 13 and thus to attach to the other elements of a device 10 for hinging and / or disengaging according to the invention, the fastening element 16 may comprise one or more recesses or notches, preferably two, said recesses or notches being for example in the form of a half-sphere or a cylinder and being able to cooperate respectively with two nipples or pins previously molded or fixed on the actuator element 13, said studs or lugs protruding from either side of said actuator element 13, respectively on the two planar faces of said actuator element 13 and positioned at the ends of the axis of rotation of said actuator element.

Alternatively or additionally, according to another embodiment of a device 10 for hinge and / or detachment according to the invention described in particular in connection with Figure 4, the fastening element 16 of the latter may be similar to a lock box, said box coming to contain all or part of the respective notched parts of the actuator element 13 and the pusher element 11. When the fastener is in the form of a box, as described in link with Figure 4, the latter can be advantageously attached to the attachment face FA of a door 20 or more generally a leaf. Said fixing element 16 in the form of a trunk may further comprise a plate for partially obscuring the recess E2.

To trigger the operation of a device 10 for hinge and / or disengage according to the invention, it is necessary to actuate in rotation the actuator element 13 thereof. Such rotational actuation may, by way of nonlimiting examples, be carried out by means of a removable third lever, not shown in the figures for the purpose of simplification. According to a non-limiting embodiment of said device 10 for hinge and / or disengage described in connection with Figure 1, to cooperate with such a third lever, the actuator element 13 of the latter may comprise a recess or cavity E3 made on a flat or convex surfaces said actuator element 13, said recess E3 being advantageously accessible from the attachment face FA. Such a recess E3 may, by way of non-limiting example, have a pentagonal or hexagonal shape, in order to be able to insert said third lever to rotate said actuator element 13, such a third lever may consist, advantageously but not exclusively , in an Allen key, preferably a hexagon key also known under the names BTR or HC (for Hexagonal Hollow or HexaCave) or known under the trademark "Allen".

As a variant, in order to offer an all-in-one device and thus to offer the operator time savings, in particular to look for a third lever if it is not at hand, according to a mode non-limiting embodiment of a device 10 for hinge and / or disengage according to the invention described in particular in connection with Figures 3a and 3b, the actuator element 13 of said device 10 may comprise a lever said lever and said cylindrical head forming one and the same physical entity. Alternatively or additionally, in order to facilitate one actuation of the actuator element 13 of a device 10 for hinging and / or disengaging according to the invention, the lever of said actuator element 13 may comprise an additional notch, not shown on the figures for the purpose of simplification, allowing a user or operator of said device to introduce a finger to grip said lever and actuate in rotation the actuator element 13 of such a device 10.

Whatever the type of lever, that is to say, removable or integrated with the actuator element, said element Actuator 13 may advantageously be arranged to be accessible and / or manipulable by the operator via the attachment face FA of a door 20 or more generally of a leaf. Indeed, to prevent damage and / or partial destruction of the door or leaf, or even the frame of the door, commonly called a frame, a device for hinge and / or disengage must be operated only when the door or the leaf is greatly, if not totally open.

Alternatively or additionally, a device 10 for hinging and / or disengaging according to the invention may advantageously be arranged so as to prevent the rotation of the actuator element 13 and / or the sliding of the pusher element 11. prevention can be achieved for example by friction or by a system, not shown in the figures for the purpose of simplification, to prevent the rotation of the actuator element 13. Such a system can, by way of non-limiting examples, consist of a hook or a ratchet, maintaining the lever of said actuator element 13 inside the leaf 20, so that it can not get up and operate said device 10. The invention can not, however, be limited to these only examples of realization. Any other system or any other solution making it possible to prevent one actuation of said device 10, by way of nonlimiting example under the simple action of the weight of the pusher element 11, may alternatively or additionally be installed and implemented.

Still in a variant or in addition, the invention provides that the device 10 can be obscured by a plate, said plate advantageously comprising a hole opening, of shape for example oblong or circular. Such a through hole makes it possible in particular to access an integrated lever of the actuator element 13 to the device 10 or to be able to insert a third lever into a recess E3 of the actuator element 13, as previously described, in particular for rotating said actuator element 13.

Also, alternatively or in addition, a device 10 according to the invention may comprise a rolling means 15 cooperating advantageously solidarily according to a suitable mechanical connection, with the end of the pusher element 11 located near the face lower IF of the door 20, as shown in a non-limiting embodiment of said device 10 in Figures 3a or 3b. Such a rolling means 15 makes it possible, in particular, to move the door 20, or more generally a leaf, without effort, for example, to its place of installation, and makes it possible to handle said door or said leaf to facilitate the coaxial alignment of the door. the female part 17 and the male part of a hinge 17. According to an advantageous but nonlimiting embodiment of a device 10 for hinge and / or disengage according to the invention described in connection with FIGS. 3a and 3b, a such rolling means 15 may consist of a ball or a retractable wheel. Optionally, a door 20 according to the invention may therefore comprise a third recess, not shown in the figures, secant of the first recess E1 and opening on the lower face FI of said door to accommodate said wheel when the device 10 is not implemented.

Advantageously but without limitation, the elements 11, 13, 16 of a device 10 for hinge and / or According to the invention, hinges according to the invention, such as those mentioned above, may advantageously be made of a material and / or a combination of materials adapted to adapt to the various stresses of wear, mechanical strength and / or chemical inertness. Preferably, but not exclusively, such elements 11, 13, 16 may mainly consist of a metal alloy, such as, by way of non-limiting examples, of steel or aluminum, and / or of one or more suitable polymers, of in particular to be able to support the weight of the door 20 when said device 10 is in active configuration. Any other material, such as wood, or combination of materials, that can support the weight of such a door 20, may alternatively be used.

As already mentioned, the invention relates according to another object a leaf, or a door, adapted to include a device 10 for hinge and / or hinge such a door 20 according to the invention. To hinge and / or disengage such a door, the invention provides that a device 10 according to the invention can be housed in the first and second recess E1 and E2 of the door 20. Thus, the pusher element 11 is housed in the first recess E1 of the door 20 and the actuator element 13 in the second recess E2, said elements 11 and 13 cooperating with each other at the intersection of said two recesses E1 and E2. The longitudinal axis of the pusher element 11 is therefore substantially parallel to a longitudinal axis of the door 20 and the axis of rotation of the actuator element 13 is substantially parallel to a central axis of said door 20. Moreover, the pusher element 11 of said device 10 can thus be mounted sliding in the first recess El and the actuator element 13, meanwhile, can be rotatably mounted within the second recess E2.

Alternatively or additionally, the door 20, or more generally a leaf, may be for all or part hollow or hollow, that is to say that such a door or such a leaf may consist only of a frame and siding for example. According to this advantageous but nonlimiting exemplary embodiment, the hollow part of said door may comprise guides, for example a tubular guide or fixing clamps, fixed along its attachment post, to guide and hold the pusher element. 11 so that its longitudinal axis is substantially parallel to a longitudinal axis of the door 20.

Still alternatively or in addition, preferably but not exclusively, the axis of rotation of the actuator element 13 may be substantially parallel to a transverse axis of said door. The flat faces of the actuator element 13 are then substantially parallel to the attachment face FA of the door 20, as shown in FIG.

Advantageously, to avoid friction on the ground when the device for hinging and / or disengaging a leaf 10 is in a passive configuration, such a situation being shown in connection with FIG. 3a, the lower end of said pusher element 11, that is, that is to say the end located near the lower face FI of the door 20, must be inside the door 20 at the edge of said lower face FI. The stroke of the pusher element 11 is thus determined so that said pusher element 11 can be completely retracted from the lower face FI of the door 20.

When installing and / or removing a door 20, that is to say when such a door is in active configuration, an operator or a user supports said door so that the bottom face FI said door is in mirror and / or parallel to the ground, then actuates the actuator element 13, for example by means of a removable or integrated lever, to rotate it. Also, the passage of the device 10, or more generally the door comprising such a device 10, from a passive configuration to an active configuration requires that the door 20 has a non-zero clearance, so that the operator can have access to said device 10 operable by and located on the FA attachment face of the leaf 20 without incurring damage to said door. By way of nonlimiting example, in accordance with an embodiment described in particular with reference to FIG. 3b, said operator can grasp said lever and then raise it in the direction of the ceiling, that is to say in the direction of the upper face FS of the door 20. The actuator element 13 cooperating with said pusher element 11 in a rack-type mechanical connection, a rotational movement of said actuator element 13 causes a translational movement of the pusher element 11 towards the ground, that is to say towards the lower face FI of the door 20. In contact with the ground, the pusher element 11 pushes the ground and thus lifts the door 20. Such a situation is particularly represented in connection with FIG. 3b , so that : the lever of the actuating element 13 is raised towards the ceiling and projects from the attachment face FA of the door 20, said lever being advantageously actuable by such an attachment face FA;

- The pusher element 11 is projecting from the lower face FI of the door 20, an overtaking distance d.

Advantageously, said overtaking distance d is at least equal to the length of the rod of the male portion of a hinge, that is, by way of indicative and nonlimiting example, approximately three centimeters, since the distance of excess d must be advantageously sufficient to allow the gondage and / or disengagement of a door 20. The overtaking distance d is further determined by the distance of the stroke of the notched portion of the actuator element 13 on the notched portion of the pusher element 11, since, as already mentioned, a rotational movement of the actuator element causes a translational movement of the pusher element. Such an excess distance d can therefore be adjusted, for example, by increasing or reducing the diameter of the cylinder of the actuator element 13. Moreover, the facility to actuate the device 10 by an operator can be adjusted by varying the number notches and / or the spacing thereof, respective notched parts of the actuator element 13 and the pusher element 11. The adaptation of a door 20 to integrate a device 10 for hinging and / or disengaging said door, can be carried out according to a method according to the invention comprising a step for digging in the panel, that is to say the frame or the core of said door 20, first and second recesses E1 and E2 secant, said first recess E1 being substantially parallel to a longitudinal axis of said door and opening on the lower face FI of said door 20 and said second recess E2 being substantially parallel to a central axis of said door and opening on the attachment face FA of the latter. As we have seen previously, such recesses E1 and E2 can be obtained by boring, by means of a drill or any other means known to those skilled in the art to create such recesses.
