FR2761108A1 - BAY BLOCK EQUIPPED WITH A MOTORIZED OCCULTATION PRODUCT - Google Patents

Abstract

The casing comprises an opening (3) which is driven by a motor with both directions of rotation (B1,B2). The motor is controlled by a pair of switches (S1,S2) for each of its directions of rotation. The switches are integral parts of the motor and are operated by remote control (6). The remote control has two levers held in an inoperative position by springs. Outside the motor, is a flexible connection (14) running over a drive drum which has a manual rotation drive component whose ends are attached to each of the levers.

Description

- 1 The invention relates to a bay block comprising a product

  occultation driven by a motor with two directions of rotation, a pair of switches for controlling the motor in each of its directions of rotation and mechanical means for manual actuation of these switches. A bay unit is a set that includes a window and a blackout product. It is equipped with a motor with two windings allowing the rotation of the motor in both directions. The switches have the effect of applying the phase of the sector to one or other of the motor windings to obtain one or the other of the

sense of rotation.

  In known bay blocks, the switches are mounted in a control box placed in the lower part of the bay block and they are actuated by push buttons. Electrical wiring is therefore necessary between the control box and the motor.

  which is located in the upper part of the bay block.

  The object of the present invention is to simplify the wiring and to facilitate the integration of a motor into

a bay block.

  The bay block according to the invention is characterized in that the switches are integrated into the motor and that the mechanical means for actuating the switches

  consist of remote handling means.

  The elimination of the wiring between the control unit and the motor has the effect of significantly reducing the cost of the bay unit. The elimination of the wiring also has the advantage of eliminating the presence of an electrical voltage at the level of the manual control and of

  facilitate compliance with safety regulations.

  According to an embodiment of the invention, remote handling means consist of a flexible link, such as a rope, cable or chain, passing over a drive drum associated with a manual drive member in rotation, the ends of this flexible link being attached to the ends of two levers mounted in the motor, intended to actuate the switches and kept in an inoperative position

by springs.

  Instead of a flexible link driven by a drum, it is possible to use a simple pair of cords or

rods, rigid or flexible.

  The accompanying drawing shows, by way of example, a mode

of the invention.

  Figure 1 is a schematic front view of a bay block. Figure 2 is a detail view, in axial section

  of a part of the engine casing fitted to the bay block.

  Figure 3 shows the electrical diagram of the motor

and his food.

  Figure 4 shows the remote manipulator, at one

  slightly larger scale than Figure 2.

  - 3 - Figure 1 shows a bay block 1 having an opening or bay 2 and a means of obscuring this opening consisting of a rolling shutter 3 unrollable from a winding tube mounted in the upper part of the baiel block and carried , on one side, by a bearing 4 and, on the other side, by a motor housed in the winding tube and whose casing 5 is fixed to a fixed support and protrudes out of the winding tube. In its lower part, the bay block is equipped with a

  remote manipulator 6 for motor control.

  The motor is a motor with two windings B1 and B2 and a phase shift capacitor C (FIG. 3), each of these windings alternately fulfilling the function of main winding and auxiliary winding depending on whether phase P of the network is applied to one or the other

  windings by means of two switches SI and S2.

  FIG. 2 represents a part of the tubular casing 5 of the engine, without the winding tube. In this housing 5 is mounted a support 7 in which are mounted the switches SI1 and S2, as well as two levers 8 and 9 articulated respectively, by their two ends, around an axis 10, respectively 11. The lever 8 extends above the switch Si and the lever 9 extends above the switch S2. A spring 12 supports the lever 8 to make it inoperative. Similarly, a spring 13 supports the lever 9 to make it inoperative. At the other end of the lever 8 is attached a strand 14a of a flexible link 14, such as a rope or a cable, another strand 14b of this link being attached to the free end of the lever 9. This flexible link 14 - 4 - is wound on a drum 15 rotatable by a button 16 constituting, with the drum 15, the manipulator 6 mounted in a housing 19. In the example shown, the flexible link 14 is guided by sheaths 17 and 18 between the housing 19 and the casing 5 of the engine. A rotation to the left or to the right of the button 16 has the effect of lowering one or the other of the levers 8 or 9 and of closing the corresponding switch, that is to say of controlling the rotation of the motor in either sense. As soon as the button 16 is released, the corresponding lever becomes inoperative under the effect of its

comes out and the engine stops.

  The construction shown and described above can be further simplified by eliminating the drum 15 and its button 16, the remote handling means simply consisting of a pair of cords or rigid or flexible rods corresponding to the strands.
