Description

BIDIRECTIONAL OR MONODIRECTIONAL MOTION TRANSMITTER DEVICE

OBJECT OF THE INVENTION

The present invention refers to a bidirectional or monodirectional movement transmitter device for opening doors and windows, installable compactly in a window leaf profile and responsible for transmitting the movement of an actuator element to transmission plates that allow the opening of a mobile leaf.

More specifically, the device object of the invention covers a series of improvements, related to its operation and installation on doors and windows, which allows to dispense with the machining operations for the installation of the device in a window profile since, due to the reduced volume that it occupies can be partially housed in the profile itself.

BACKGROUND OF THE INVENTION

The use of bidirectional or monodirectional transmission devices is widely extended in the sector of aluminum doors and windows.

In most cases, these directional devices are installed in the mobile profile of the window or door, and transmit a movement to some edges, through which the transmission means move, which in some cases are grooved and in other cases are a set of two plates, one fixed or with a grooved support and the other mobile or transmitting. Directional devices use a main pinion that receives a torque from the actuator element, which is usually a door or window handle with a longitudinal axis.

In order to make the transmission in two directions, bidirectional or monodirectional, it is necessary to reverse the rotation of the main pinion, and there are multiple patents and utility models detailing different ways of achieving the rotation. Most of the solutions involve mechanisms with a size that makes it necessary to perform machining on the profiles, at a depth level lower than that of the movement transmission plane to the bidirectional or monodirectional plates. In patent document ITB0930102A1, for example, a bidirectional or monodirectional device is disclosed with a main transmission pinion designed for a 90° turn of the handle ^, which drives a belt at one of its ends and at the opposite end, engages with different tooth pitch with an inverter pinion, which engages a second rack through its opposite diameter, which is responsible for transmitting the movement opposite to that caused by the rotation of the main pinion to the channel through which the transmission plate is usually mounted. The total size of the mechanism makes it necessary to perform machining on the profiles in order to insert the mechanism, since the reference for actuation is the plane along which the transmission plates move. Patent application DE9212950U1 shows another solution in which the main gear transmits its movement to a rack at one end and at the other end it engages with two reversing pinions that engage with the second of the mechanism's transmission plates.

However, in the proposed solutions it is necessary to carry out specific machining to install the transmission box of the mechanism, since the devices are considerably larger in volume than the profiles, with the investment of time and associated cost that this entails.

DESCRIPTION OF THE INVENTION

The present invention deals with a bidirectional or monodirectional movement transmission device designed to be partially housed inside a C-shaped window interior profile provided with two edges that houses at least one transmission platens that allow a window to be opened or closed. .

The device comprises a grooved support intended to be partially housed in the inner profile limited by a lower face and a grooved upper face provided with a cylindrical cavity and a positioning hole intended to receive a fixing element that interferes on one of the edges of the device. inner profile.

The device in turn comprises a pinion with the possibility of rotation, partially housed in the cylindrical cavity and which is intended to be linked to an axis of rotation of an actuator element arranged perpendicular to a plane of rotation of the pinion, which is responsible for transmitting to the pinion a torque. The device comprises at least one longitudinal sliding piece partially embedded in the upper face of the grooved support intended to be linked to a transmission plate and provided with a first end that protrudes longitudinally from the grooved support and is partially housed in the inner profile and a second end provided with an internal rack surface that meshes with the pinion and in an open situation caused by the rotation of the pinion, the sliding part moves with respect to the grooved support in the longitudinal direction of the internal profile.

In addition, the device comprises a closing cover fixed to the grooved support that partially covers the sliding parts and comprises a central hole intended to partially house the pinion and the shaft of the actuator element.

In this way, when a user turns an actuating element such as a handle, the axis of the handle enters perpendicular to the movement transmission plane and rotates the pinion, where the pinion in turn generates a displacement movement of the sliding parts along the profile that moves the transmission plates, also known as transmission bars, or espagnolette plates, which are part of the movement transmission system to other parts that make up the blocking system.

Thanks to the positioning hole designed to receive a fixing element, once the support has been inserted in the profile, it is fixed in it, locking the position of the cover and the sliding parts. The positioning hole is preferably a threaded hole.

The device is designed to be compact and to be able to be installed inside door or window profiles, grooved on the edges or guiding edges arranged inside the profile.

With this device an effective transmission of movement is achieved and it is also easy to install since, thanks to its configuration, it is not necessary to make specific machining on the profile to install it.

By being able to use the same profile both for the installation of the transmission plates and for installing, positioning and blocking the grooved support of the transmission device, the device provides great speed in installation and wide versatility, since it can be used in a wide range of applications. range of profiles. This arrangement of the bidirectional or monodirectional device makes it possible to carry out a closing maneuver at the ends of the profile, the profile being a tubular profile, from a central point, without making additional machining to install the device.

The device may preferably comprise two sliding parts that engage with the pinion at diametrically opposite points, so that the device functions as a bidirectional device that can be linked by means of the sliding parts to respective transmission plates.

The grooved support is limited by two lateral faces of the grooved support from which first projections intended to be housed inside the inner profile can extend, ensuring retention of the support inside the profile without the need for machining operations.

For the same reason, the sliding pieces are limited by two lateral faces of the slider from which a few second projections intended to be housed inside the inner profile can extend, so that the sliding pieces are retained inside the profile with the possibility displacement along a longitudinal direction of the profile.

On the other hand, the pinion can comprise a pinion cavity that extends perpendicular to the grooved support in a complementary way to the axis of the actuator element and that is intended to partially house said axis. In this way, the shaft is housed perpendicularly to a plane of rotation of the pinion and it is ensured that the coupling between the pinion and the shaft is optimal. If the axis of the actuating element is, for example, a square spindle with a quadrangular shape, the pinion cavity also has a quadrangular shape.

Preferably, the sliding pieces can comprise a lower contact surface from which pivots extend in the vicinity of each first end intended to be housed in through holes of the transmission plates so as to ensure the transmission of movement between the pieces sliders and the transmission plates and this union can be removable.

Finally, the cover may comprise two first lateral holes arranged symmetrically on each side of the central hole and the grooved support comprises two second lateral holes opposite the first lateral holes intended to accommodate some joining sectors of the actuator element, where said central holes are preferably threaded.
