Abstract

Multiple control buttons (11,12) control movement of slats in opposite directions and movable control element (2b) moves in two directions along a theoretical axis of operation. The buttons are positioned outside of an exclusion zone defined by two straight lines intersecting in center of movable element and forming an angle (alpha ) of 60 [deg], bisector of which is parallel to theoretical axis. The zone is also defined by a circle whose center is on movable element and circumference is separated from latter by a distance of 20 mm.

Description

The invention relates to a device for issuing control commands for a motorized steerable blind, comprising control knobs and a movable control element movable in two directions in a theoretical direction of manipulation, these control knobs and this movable control element being disposed on a first face of the transmission device.

Requirement EP 1 486 640 , which is incorporated by reference in the present application, discloses an order issuing device 30 (shown in FIG. figure 1 ) to control movements of the blades of a blind. The blades are movable in translation by pressing on the control buttons 31, 32 and movable in rotation by manipulation of a control wheel 33. Such a device makes it more intuitive actions required to control the blind. However, the manipulations of the wheel pose problems. Indeed, unlike pressing a button where, once the button is pressed, the gesture of the user is blocked, nothing allows the control device to stop the gesture of the user during the manipulation of the scroll wheel. If this gesture extends beyond the wheel, it may give rise to inadvertent presses on control buttons 31, 32.

In addition, it has been noticed that the proximity of buttons intended to control blade movements in opposite directions often gives rise to errors of manipulation by the user. This problem could be solved by moving the buttons away from each other, but this would be at the cost of a less compact controller.

The object of the invention is to provide an order issuing device to overcome the aforementioned drawbacks and to improve the known devices of the prior art. In particular, the invention proposes a device for issuing orders making it possible to avoid the occurrence of unintentional actions by the user while avoiding, on the one hand, that gestures not controlled by the user give rise to presses buttons and avoiding the other hand that the functions of the buttons are confused by the user.

In a first embodiment, the order issuing device according to the invention is characterized by the characterizing part of claim 1.

In a second embodiment, the command-issuing device according to the invention is characterized by the characterizing part of claim 2.

It has indeed been noticed that the presence of a wheel on a transmitting device provides the user with an excellent tactile mark to determine the position of his hand relative to the device. Thus, by arranging a first button controlling the movements (in particular the translation movements) of the blades in a direction on one side of the wheel and another button controlling the movements of the blades in the other direction on the other side of the wheel. wheel, it prevents the user from confusing the buttons.

Various alternative embodiments of the device according to the invention are defined by the dependent claims 3 to 6.

The appended drawing shows, by way of example, various alternative embodiments of a device for issuing control commands for a blind with blades according to the invention.

• The figure 1 is a diagram of an order issuing device known from the prior art.
• The figure 2 is a diagram of a transmission device according to the invention controlling a blind.
• The Figures 3, 4 , 5 and 6 are detailed views of the various embodiments of the transmission device, the figure 4 being a sectional view and the figure 5 being a side view.

The device 1 of motorized slatted blinds shown in FIG. figure 2 comprises a command transmitter 2 provided with a first control interface 2a and a second control interface 2b, a command receiver 6 linked to a mechanical assembly 4 comprising horizontal blades 5 which are orientable about their axis, a motor 3 of orientation of the blades and a motor 3 'of vertical displacement of the blades. The movements of vertical displacement and orientation of the blades can be obtained by the action of a single motor.

The first control interface 2a comprises two control buttons 11, 12. The buttons 11 and 12 make it possible, in a conventional manner, to respectively control the raising and lowering of the blind blades by activating the motor 3 '.

The second control interface 2b includes a wheel. This wheel, represented in Figures 3 and 4 is rotatable about an axis D2. It allows for example to operate a first or second electrical contact according to its direction of movement and to control accordingly the rotation of the motor 3 in one direction or the other.

The two interfaces are arranged on the same face 24 of the so-called front panel control device. This face is not necessarily flat.

The wheel may be replaced by another movable element such as a button 2b 'toggle movable in rotation about an axis D2' between two stops (as shown in FIG. figure 5 ) or a movable cursor between two stops in a groove formed on the front face of the transmitting device. To maneuver this element, it is necessary that the user exerts an action on it in a theoretical direction of manipulation defined as the projection of the displacement of any point of the element on the front face of the transmitting device when it is manipulated, This direction is represented by the axis D1.

The advantage related to the embodiments of the movable element, is their mode of actuation: indeed, to maneuver the mobile element, the user must drag it and accompany its movement. This is particularly intuitive for controlling the orientation of the blades in that the movement is slow and monitored by the user, throughout the blade orientation maneuver.

However, to prevent a gesture of maneuvering the movable element unintentionally extended by the user beyond the movable element on the front face does not trigger the issuance of an order, it is expected on the front face of the transmission device an exclusion zone A, that is to say an area in which a mechanical action exerted on the transmission device does not cause order transmission to the receiver of orders 6. In this area, it is necessary that no button not at all, or at least no button is fully arranged. Indeed, the geometry of a button can encroach on this zone provided that an action on the button at this level does not cause order transmission to the command receiver 6.

This exclusion zone extends at least on either side of the movable element in the theoretical direction of manipulation and is adjacent to the movable element. It furthermore extends sufficiently for a gesture of maneuvering the moving element unintentionally extended by the user beyond the movable element on the front face does not trigger the issuance of an order

In a first variant embodiment, the exclusion zone A is delimited by two straight lines C1, C2 intersecting at the center of the movable element and forming an angle α of 60 ° whose bisector is parallel to the theoretical direction of manipulation.

The exclusion zone is further delimited by a circle 21 centered on the movable element and distant by a distance d from the movable element, this distance being equal to 20 mm.

In a preferred variant, the angle a is 50 ° and the distance d is 10 mm.

Advantageously, the transmission device comprises, in the exclusion zone A, at least one abutment 22 forming a protuberance with respect to the level of the front face 24 in the vicinity of the movable element, for example in the area referenced B on the figure 4 . This stop may for example consist of a slope on the front face (as shown in FIG. figure 4 ) or in a boss. Such an abutment makes it possible to limit the movements of operation of the mobile element that can be extended. unintentionally by the user beyond the movable element on the front face. Preferably, such a stop is disposed on either side of the movable member.

The control buttons 11 and 12 are arranged on the front face of the transmitting device on either side of the movable element, preferably in the direction perpendicular to the theoretical direction of maneuvering. The buttons may be arranged symmetrically with respect to the movable member.

In an embodiment variant represented in figure 6 , the control device may have other control buttons. It may in particular have buttons 13 and 14 respectively controlling the displacement of the blades to a high intermediate position and the displacement of the blades to a lower intermediate position or the movement of the blades at reduced speed. In the case where the transmission device comprises four buttons, they can be arranged relative to each other symmetrically with respect to the axes D1 and D2.

The control buttons have for example the shape of crown portions.

Advantageously, the movable element can be used to control the stop movement of the blades by exerting on it a pressure along a substantially perpendicular axis D3. Thus, a third contact is necessary to perform this function. Its operation is similar to that described in paragraph 37 of the publication of the application EP 1 486 640 A1 .

The command transmission device may be a wired remote control as described above, but it may also consist of a wireless portable remote control communicating for example by means of radio waves or infrared with the command receiver. In this case, the various actions exerted on the various control buttons, sliders or knobs are translated into the transmission device by an electronic device into an electromagnetic signal.

The emission device according to the invention can obviously be used to control any type of awning or curtain with adjustable blades.
