Definitions

• the present invention relates to a portable device for controlling the raising and lowering of the roller shutters.
• the first solution is the most attractive; however, it requires the installation of at least one motor per shutter and therefore leads to a significant cost.
• It describes a device which fits directly onto the conventional handle, without modification or arrangement thereof; it relates to a portable device for the operation of roller shutters intended on the one hand to be rotated about an axis and on the other hand provided to cooperate, via a specific adaptation part, with a tradional handle for controlling said roller shutters characterized in that said specific adaptation part comprises at least two recesses, the first intended to receive the last end of said traditional handle, the second transverse to said first recess, intended to maintain, in cooperation with said first recess, the axis of said traditional handle in the extension of the axis of said rotation.
• the present invention also claims a portable device for controlling roller shutters equipped with such a device.
• the invention will be better understood on reading the description below:
• FIG. 1 shows a traditional handle for controlling shutters in working configuration.
• FIG. 2 shows a traditional handle in the configuration adapted to the present invention.
• FIG. 3 shows a device according to the present invention.
• FIG. 4 shows such a device in cooperation with the traditional handle.
• FIG. 5 shows, in a preferred embodiment according to the invention, the part of the device capable of communicating the rotational movement to the device.
• FIG. 1 shows a traditional handle for controlling roller shutters; there are the segments (1), (2) and (3) respectively articulated around the axes (4) and (5); in the "rest" position, these 3 segments are aligned and define what will be called hereinafter the axis (6) of the traditional handle; in the working position ( Figure 1) the segment (2) is placed in the horizontal position, the segment (3) in the vertical position and the segment (1) held in the direction of the axis (6).
• FIG. 2 shows the same traditional handle in a configuration compatible with the invention; it will be noted that the segments (1) and (2) are aligned along the axis (6) and that the segment (3) is brought into a horizontal position.
• the device comprises a specific adaptation part (7) capable of being rotated about an axis (8) by means, for example, of a plate (9); the adapter piece (7) has a first recess (10) and a second recess (11), transverse to the first, and defining with it in return (12).
• FIG. 4 shows the device in operational configuration; the recess (10) receives the end (3) of the traditional handle; the recess (11), in cooperation with the recess (10) and thanks to the return (12) defined by these two recesses maintains the axis (6) of the handle in the extension of the axis (8) of rotation .
• the device according to the invention can be rotated by any motion generator this in order to constitute a complete device intended for the operation of the roller shutters.
• the device according to the invention could then be "removable” or “integral” with said generator.
• the latter will preferably comprise at least 1 electric motor which may be supplied by the alternating electric current of the sector and / or by rechargeable batteries or batteries; it will present a grip handle and offer studied ergonomics; it must also, of course, be capable of delivering 2 movements of rotation of the same axis but in opposite directions (raising and lowering of the flaps).
• the device for operating the roller shutters will have a mechanical arrangement intended to allow, when the movement generator is in the non-operating position, the free rotation of the plate (9); therefore, said arrangement will allow free positioning of the specific part (7) positioning which will depend, of course, on the positioning of the end (3) of the handle, that is to say the degree of opening or closing the shutter; there is shown in Figures 3, 4 and 5 a preferred embodiment of such an arrangement.
• the plate (9) supporting the specific part (7) has a cam (13) which defines 2 extreme projections (14) and (15);
• the part (16) (FIG. 5) intended to transmit the rotational movement to the plate (9) has, in elevation, also a cam (17) whose ends (18) and (19) cooperate, for transmitting the said rotation with the plate (9) and as a function of the direction of rotation, respectively with the ends (14) or (15) of the cam (13): it is easily understood that the more the ends (14) and (15) of a part and (18) and (19) on the other hand are close to each other (that is to say the smaller the cams (13) and (17) are) and the more the plate (9) therefore the specific part (7) will have a large free rotation.
• the device may be fitted with a torque limiter, that is to say equipment allowing automatic uncoupling, when the resistive torque offered by the handle exceeds an adjustable set value (end stops of stroke, hard points, etc.), the specific adaptation part of the rotation generator.
• a torque limiter that is to say equipment allowing automatic uncoupling, when the resistive torque offered by the handle exceeds an adjustable set value (end stops of stroke, hard points, etc.), the specific adaptation part of the rotation generator.
