Description

Motorized drive device for a concealment device, concealment device and associated assembly and disassembly methods

The present invention relates to a motorized drive device for a concealment device, in other words a motorized drive device for a concealment device. This motorized drive device is intended, in other words is configured, to move at least one screen along a rod following a sliding movement.

The present invention also relates to a concealment device equipped with such a motorized drive device, a method of mounting such a motorized drive device on a rod of a concealment device, as well as a method dismantling such a motorized drive device relative to a rod of a concealment device.

Generally speaking, the present invention relates to the field of curtains comprising a motorized drive device moving a screen relative to a rod following a sliding movement, between at least a first position and at least a second position.

We already know the document CN 113 475 926 A which describes a motorized drive device for a concealment device. The motorized drive device comprises a housing, a motor unit and a first holding device. The motor unit is housed inside the housing. The first holding device is connected to the housing, so as to hold the housing relative to a rod of the concealment device. The motor unit includes an electric motor and two drive wheels. Each drive wheel is configured to be rotated around a first axis of rotation by means of the electric motor and to be brought into contact with a surface of the rod, so as to move the motorized drive device along the rod following a direction of movement. The first holding device includes a first suspension element. The first suspension member is configured to be in either an unlocked state or a locked state relative to the housing. The housing includes a first housing. The first housing is configured to receive a first portion of the first suspension element.

However, this motorized drive device has the disadvantage of fixing the first suspension element in the first housing of the housing by screwing a first locking element. The first suspension element includes a first threaded rod. The first locking element is a nut. The fixing of the first suspension element relative to the first housing of the housing is implemented by screwing the first locking element onto the first threaded rod of the first suspension element, until a surface of the first element comes into contact blocking with a surface of the housing. The first threaded rod of the first suspension element includes two flats and the first housing of the housing includes two flat surfaces. In addition, each flat of the first threaded rod is configured to cooperate with one of the flat surfaces of the first housing, so as to block the rotation of the first suspension element relative to the first housing, when the first threaded rod is inserted at inside the first accommodation.

Thus, such an assembly of the first suspension element relative to the first housing of the housing makes the orientation of a second part of the first suspension element intended to be arranged inside a recess in the rod, through of a slot provided along the length of the rod, since the first suspension element is locked in rotation inside the first housing of the housing. Only a rotation of the motorized drive device can make it possible to orient the second part of the first suspension element relative to the rod.

Document CN 113 475 926 A also describes that the motorized drive device further comprises a second holding device, similar to the first holding device described previously.

The only difference between the first and second holding devices is that the first housing of the first holding device is of closed section, so that the first threaded rod is inserted in an axial direction inside the first housing of the housing, then that a second housing of the second holding device is of open section, in other words is split, so that a second threaded rod can be inserted, through a notch, in a radial direction inside the second housing of the housing .

Document CN 113 475 926 A further describes a method of mounting the motorized drive device on the rod comprising the following steps and implemented in the order mentioned:

- insertion of the first threaded rod of the first suspension element inside the first housing of the housing, in an axial direction relative to the first housing,

- screwing the first locking element onto the first threaded rod,

- insertion of the second part of the first suspension element inside the recess of the rod, through the slot of the rod, by positioning the housing in a direction perpendicular to the direction of movement of the drive device motorized along the rod, in other words relative to a longitudinal direction of the rod,

- rotation of the housing relative to the rod, so that the housing is parallel to the direction of movement of the motorized drive device along the rod, in other words by a value of 90°,

- insertion of the second part of the second suspension element inside the recess of the rod, through the slot of the rod, by positioning the second suspension element perpendicular to the direction of movement of the drive device motorized along the rod,

- rotation of the second suspension element relative to the rod, so that the second suspension element is parallel to the direction of movement of the motorized drive device along the rod, in other words by a value of 90°,

- insertion of the second threaded rod of the second suspension element inside the second housing of the housing, through the notch of the second housing, in a radial direction relative to the second housing,

- screwing the second locking element onto the second threaded rod, and

- adjustment of the pressure of the drive wheels on the surface of the rod, by screwing the first and second locking elements more or less in relation to the first and second threaded rods.

Consequently, mounting the motorized drive device on the rod is long, complex and requires a certain amount of dexterity on the part of a user.

The present invention aims to resolve the aforementioned drawbacks and to propose a motorized drive device for a concealment device, a concealment device comprising such a motorized drive device, a method of mounting such motorized drive device on a rod of a concealment device, as well as a method of dismantling such a motorized drive device relative to a rod of a concealment device, making it possible to simplify the installation in place of the motorized drive device relative to a rod of the concealment device, to simplify the maintenance of the motorized drive device and to simplify a replacement of a suspension element by another of the same or different type, while minimizing the costs of obtaining the motorized drive device.

Advantageously, the housing 43 is configured to be held, in other words is held, in a static orientation relative to the rod 4, via the first and second holding devices 37, 39, in particular in the assembled configuration of the device concealment 3.

Thus, this static orientation of the housing 43 relative to the rod 4 is implemented following the maintenance of the motorized drive device 10 relative to the rod 4 via the first and second holding devices 37, 39 cooperating with the rod 4, whether during electrical deactivation of the electric motor 11 or during electrical activation of the electric motor 11.

In this way, an angle value, not shown, between the median plane P of the housing 43 relative to the longitudinal axis A4 of the rod 4 is constant, whether when stopping the motorized drive device 10 relative to the rod 4 or during a movement of the motorized drive device 10 along the rod 4, implemented by the electrical activation of the electric motor 11.

Preferably, the angle value between the median plane P of the housing 43 relative to the longitudinal axis A4 of the rod 4 is of the order of 90°.

Such a construction of the motorized drive device 10 makes it possible to minimize a stiffness value of the or each elastic return element 44.

Due to the holding of the motorized drive device 10 relative to the rod 4 via the first and second holding devices 37, 39, the stiffness value of the elastic return element(s) 44 determines an initial contact pressure of the drive wheel 13 on the rod 4, as long as the electric motor 11 is electrically deactivated.
