Definitions
- the invention relates to a motorized closure, blackout or sun protection device comprising at least one rollable element, one end of which is kinematically linked to a rollable element drive roller and the other end of which is attached to strands.
- the variation in diameter of the windable element in this case the wound fabric causes a variation in the torque exerted by the elastic means on the fabric drive roller. If it is assumed that the system is balanced in the rolled up position, the reduction in the resistive torque during unwinding has the effect of giving rise to a resulting torque, which tends to cause the rewinding of the fabric.
- the increase in the torque on the belt drive roller is added to the decrease in the resistant torque on the canvas winding roller, which further increases the resulting torque which tends to cause the canvas to rewind. An increasing effort is therefore necessary to unroll the canvas.
- a brake is also necessary to keep the canvas unrolled.
- This brake generally consists of an electromagnetic brake or permanent friction and it also consumes energy during the movement of the fabric. Consequently, the supply of such devices by means of an autonomous source, such as cells or a battery, is practically not possible in a reasonable space.
- the object of the present invention is to provide a closure, concealment or protection device solar, as defined above, whose electric motor is powered by an autonomous current source. For such a device to be of practical interest, its current consumption must be low.
- the device according to the invention is characterized in that it constitutes a balanced system.
- the linear weight of the windable element, in particular of the fabric, and the linear weight of the traction strands, taken together are equal. Subsequently, for simplicity, it will only be a question of "canvas”, but it is clear that this term can always be replaced by "rollable element”.
- the canvas drive roller and the strand drive roller are advantageously coaxial and integral in rotation. They can consist of a single roll.
- the pull strands are provided with at least one counterweight compensating for the weight of the bar.
- the canvas drive rollers and the strand drive rollers have the same diameter, one of the ends of the canvas and of the strands is free, the device comprises a pressure roller bearing against the drive rollers and the fabric and the strands pass in opposite directions between the drive rollers and the pressure roller for their drive in opposite directions and the device comprises at least one magazine in which the fabric accumulates during the opening of the device and the strands when closing the device.
- the device includes conical pulleys with a helical groove integral in rotation with the canvas drive roller, pulleys on which are wound and unwound in ropes provided with counterweights, the torques generated by these counterweights compensating for the variations in torques generated by the variations in the winding diameters of the fabric and the traction strands.
- the strand drive roller of traction has two frustoconical parts provided with helical grooves in which are wound the traction strands.
- the end of the fabric to which the traction strands are connected is provided with a hollow bar in which is housed a spring working in traction and at the ends of which the strands are attached traction.
- the device comprises two fabrics and two canvas drive rollers each associated with a drive roller for pulling strands and constituting two pairs of rollers, each of these pairs of rollers serving as return rollers for the rolls of the other pair.
- the accompanying drawing shows, by way of example, some embodiments of the invention.
- Figure 1 is a side view of a first embodiment.
- Figure 2 is a front view of this first embodiment.
- Figure 3 is a side view of a second embodiment.
- Figure 4 is a front view of this second embodiment.
- Figure 5 is a side view of a third embodiment, canvas half unwound.
- Figure 6 is a front view of this third embodiment.
- Figure 7 shows the third embodiment, fully unwound canvas.
- Figure 8 is a side view of a fourth embodiment.
- Figure 9 is a front view of this fourth embodiment.
- Figure 10 is a side view of a fifth embodiment.
- Figure 11 is a front view of this fifth embodiment.
- FIG. 12 represents a variant of the fifth embodiment.
- Figure 13 is a side view of a sixth embodiment.
- FIG. 14 represents a variant of this sixth embodiment.
- Figure 15 is a front view of this variant.
- the device shown in Figures 1 and 2 comprises a roller 1 which is both a drive roller for a fabric 2 and for two traction strands 3 and 4 in the form of strips.
- the canvas and strand traction rollers are therefore here combined and the canvas and the traction strands together have the same linear weight.
- One of the ends of the fabric is provided with a bar 5, the end portions of which are fixed to the traction strands 3 and 4, on which counterweights 31 and 32 are fixed, the total weight of which is equal to the weight of the bar 5.
- the traction strands 3 and 4 pass over a deflection roller 6 parallel to the roller 1.
- the rollers 1 and 6 are of course mounted on shafts themselves mounted in bearings not shown.
- the shaft of the roller 6 can move transversely and this shaft is stressed by an elastic tensioning means 7, for example a pair of springs attached to the ends of the shaft so as to maintain a certain tension on the strands of traction and canvas.
- an elastic tensioning means 7 for example a pair of springs attached to the ends of the shaft so as to maintain a certain tension on the strands of traction and canvas.
- the particularity of this embodiment is that one of the ends of the fabric 2 and the strands 3 and 4 is free and that the fabric and the traction strands are entrained by adhesion by the drive roller 1.
- the device is equipped with a pressure roller 8 held against the roller 1 by an elastic traction means, for example a pair of springs 9.
- the fabric 2 and the strands 3 and 4 pass between the drive roller 1 and the pressure roller 8.
- the fabric 2 and the strands 3 and 4 are poured into a respective store, the accumulation of the fabric and the strands in the stores being schematically represented by the pleated parts 10 and 11 in Figure 1.
- the device is driven by a motor acting either on the roller 1 or on the pressure roller 8.
- the winding radii of the fabric and the strands on the roller 1 are identical and remain constant regardless of the position of the fabric 2 because there is no superposition of several fabric turns and traction strands. Consequently, the torque resulting from the traction of the fabric and of the traction strands on the main roller 1 is zero whatever the position of the fabric, so that the force exerted by the elastic tensioning means does not not vary.
- the linear speed of the fabric and the strands is identical at all times.
- the system In vertical or oblique use of the fabric 2, the system is balanced in any position of the fabric because the weight of the unrolled fabric is constantly equal to the weight of the traction strands and the weight of the bar 5 is balanced by the counterweights 31 and 32.
- the traction strands could consist of cables or ropes.
- at least the roller 1 will have grooves intended to receive these cables or cords. The depth of these grooves will be such that the pressure of the pressure roller 8 exerts sufficient pressure on the cables or ropes for their drive.
- the fabric and the strands could be entrained by pins.
- FIG. 3 and 4 The embodiment shown in Figures 3 and 4 is derived from the first embodiment.
- the simple deflection roller 6 is replaced by an assembly identical to that constituted by the drive roller 1, the pressure roller 8, the fabric 2 and the traction strands 3 and 4.
- the elements of this second assembly have therefore simply designated by the same references with the sign '.
- This second embodiment also differs from the first embodiment in that the end bar 5 of the first fabric 2 is attached to one of the ends of the traction strands 3 'and 4' of the second system and conversely and in that the spacing of the traction strands 3 and 4 is greater than the spacing of the traction strands 3 ', 4' so as to allow the traction strands to cross in a plane.
- the elastic tensioning means 7 acts on one of the rollers 1 or 1 '.
- the linear weight of the traction strands may be equal to or different from that of the fabric.
- the strands 3 and 4 of the first system are therefore driven by the roller l 'of the second system and vice versa. We could therefore also say that there is no deflection roller but only traction rollers. As in the first embodiment, the free strands of each system are driven by the rollers 1 and 8, respectively l 'and 8' of the other system.
- the system In vertical use, the system is always balanced because the weights of the unwound parts of the fabrics, the weights of the traction strands and the weights of the bars 5 and 5 'compensate for each other.
- This device can also be driven by a single motor acting on one of the rollers 1, 8, l 'or 8'.
- the advantage of this embodiment is that the time required for closing and opening the device is halved, since each canvas covers only half of the space to be obscured, while the masses set in motion are barely higher than in the first embodiment. This embodiment therefore allows additional energy savings. This also applies to the embodiments according to Figures 8, 9 and 13 to 15.
- the embodiment shown in Figures 5 and 6 essentially differs from the previous embodiments in that the fabric 20 is wound on its drive roller 1 while the traction strands 15 and 16 are unwound from their rollers d drive 17 and 18.
- the linear weight of the fabric is equal to the linear weight of the traction strands taken together and the bar 5 is balanced by counterweights 31 and 32.
- One end of the fabric 20 is attached to the drive roller 1 while its other end, again provided with a bar 5, is attached by this bar to one of the ends of the traction strands 15 and 16, the other ends are attached to drive rollers 17 and 18 coaxial and integral in rotation with the canvas drive roller 1 and of diameter equal to the diameter of the roller 1.
- the straps 15 and 16 constituting the traction strands are wound in grooves.
- the straps 15 and 16 pass over references 19 and 21 also with grooves.
- the winding diameter of the fabric and of the traction strands varying in opposite directions the couples exerted also vary in opposite directions and therefore tend to create a resulting torque different from zero.
- two counterweights 10 and 11 are provided, suspended respectively from two cords 12 and 13 which are wound respectively on two frustoconical pulleys 14 and 14 'with helical groove.
- the cord 13 is wound up when the fabric 20 is unwound, and the wound diameter of the cord 13 decreases like that of the fabric. Consequently, the torque generated by the weight 11 decreases as well as that generated by the fabric.
- the weight 11 and the taper of the pulley 14 ′ are chosen so that the reduction in torque generated by the weight 11 compensates for the reduction in the torque generated by the fabric and vice versa.
- the embodiment shown in Figures 10 and 11 is related to the embodiment shown in Figures 5 and 6. It takes the canvas drive roller 1 on which is attached and rolls up the canvas 20, the references grooved 19 and 21 and the springs 7 retaining the axis of the references 19 and 21, and the bar 5 fixed to one end of the fabric 20.
- the traction strands consist of ropes or cables 22 and 23, one end of which is attached to the bar 5 as above and the other end of which is attached to " a winding drum 24, respectively 25, these drums being of frustoconical shape and having a helical groove in which the traction strands 22 are wound and unwound and 23.
- the traction strands 22 and 23 are wound on the drums 24 and 25 when the fabric 20 is unwound and vice versa.
- the conicity of the drums 24 and 25 has the effect of compensating for the reduction in the diameter of the winding of the canvas 20 lor s of its course, so that the torques exerted by the traction on the fabric 20 and by the traction on the strands 22 and 23 are equal in all the positions of the fabric.
- the linear weights of the fabric and the traction strands are equal and the weight of the bar 5 is balanced by counterweights 31, 32. In vertical or oblique use the system is therefore balanced in all positions.
- the axis 25 of the references 19 and 21 is fixed.
- the bar 5 is replaced by a hollow bar 26 carrying at its ends return pulleys 27 and 28 and containing a spring 29 working in traction and at the ends of which are attached the ends of the traction strands 22 and 23.
- the spring 29 replaces the springs 7 to maintain tension on the traction strands and the fabric.
- the variant shown in FIG. 12 can be made head to tail, as shown in FIGS. 13 and 15.
- the traction strands 22, 23 of the first fabric 20 cross the traction strands 22 ', 23' of the second fabric 20 '.
- the frusto-conical drums 24 ', 25' serve to return the strands 22, 23 of the fabric 20, while the frusto-conical drums 24, 25 serve to return the strands 22 ', 23' of the fabric 20 '.
- a spring, such as spring 29, is mounted in one of the bars 26 and 26 '. In this embodiment, the blind is closed when the bars 26 and 26 'meet on the axis 30 passing through the crossing point of the traction strands.
