Definitions
- the invention relates to a rolling shutter for a door, window or the like, comprising an apron which winds and unwinds from a drum controlled in rotation by a driving device, such as a winch or the like, and mounted in free rotation. on an axis divided into two sections located in the extension of one another, one of these axis sections being provided with a return spring facilitating the winding of said deck.
- the invention relates more particularly to the industry specializing in the manufacture of roller shutters and more generally of any type of removable cover.
- roller shutters for door, window or the like.
- these roller shutters consist, essentially, of an apron formed of a plurality of juxtaposed blades and articulated with respect to each other, and of a mechanism making it possible to wind or unwind said apron.
- the aforementioned mechanism comprises a drum on which and from which the apron is wound or unwound, said drum being controlled in rotation by a drive device, such as a winch or the like, itself actuated by means any control, such as chain, strap, linkage or electric motor.
- a drive device such as a winch or the like
- the latter is mounted on an axis divided into two sections located in the extension of one another and having projecting relative to the ends of said drum.
- these protruding parts of the axis sections are introduced into bearings fixed in the upper part of the door or window frame to maintain the drum in a substantially horizontal position and so as to ensure deployment of the deck in a plane parallel to said door or window.
- these bearings are secured to the lateral flanges of a box enclosing the entire winding and unwinding mechanism of the deck.
- roller shutters are also provided with elastic return means making it possible to compensate for the weight of the curtain and facilitate the winding of the latter.
- elastic return means are requested during the deployment of the apron simultaneously ensuring the control of this operation and avoiding sudden fallout of the latter.
- These elastic return means in general, consist of a helical spring engaged on one of the axis sections, supporting the drum. One end of this spring is connected either directly or by an intermediate piece to the latter, the other end being made integral with said section of axis.
- this one-sided adjustment of the roller shutter hardly facilitates the centering of the latter relative to the door or window. In some cases, it is necessary to substantially cut the jamb of said door or window to properly arrange this roller shutter.
- document FR-A-2,137,411 also discloses a roller shutter drum in the form of a cylindrical envelope rotatably mounted on two sections of axis projecting, respectively, at each end of said drum.
- elastic return means constituted by a helical spring having the function of partially compensating for the weight of the deck when it is wound up. on the drum but, also, to slow the descent of this deck during the course.
- this helical spring is made integral, at one of its ends, with a cylindrical end piece inserted in one of the ends of the drum and forming a bearing, in the sense that it ensures the rotational mounting of this drum on this section of axis provided with elastic return means.

- a support disc serving as a support bearing.
- this section of axis is effectively mounted to rotate freely in the central bore with which this support disc is provided, the latter is, moreover, on the one hand, immobilized in rotation relative to the drum while being capable of moving axially, inside the latter and, on the other hand, made integral in axial translation of said axis section.
- the drum driving device such as a winch or the like
- the drum driving device is mounted on the section of sliding axis.
- it is absolutely essential to maintain cooperation between the drive device and the end of the drum regardless of the length of the projecting part of the axis section relative to this end.
- said axis section is provided with a series of perforations serving as a passage for a pin holding the drive device applied against the end of the drum.
- this pin since this pin also has the function of immobilizing in translation the axis section in the drum, it can only be put in place after having introduced the end of this axis section into the corresponding level. Due to generally difficult access, this pin setting operation can be particularly delicate and tedious.
- the object of the present invention is to remedy all of the aforementioned drawbacks.
- the rolling shutter for door, window or the like includes means making it possible to position the drive device indifferently on one or the other of the axis sections and to ensure its cooperation with said axis. drum.
- Figure 1 shows a schematic view, in elevation and in section, of the winding drum of the roller shutter according to the invention.
- the roller shutter 1, for door, window or the like, according to the invention, consists essentially of an apron (not shown) formed by a plurality of juxtaposed slats and connected together by an articulation which, in certain case, can be telescopic.
- This roller shutter deck 1 is able to wind and unwind from a drum 2, generally disposed horizontally and in the upper part of said door or window.
- this drum 2 is formed, in many cases, by a tubular section of polygonal section, and, more particularly, of hexagonal section. This configuration facilitates the winding on this drum 2 of the first blades of the deck located in the upper part of the latter.
- the roller shutter 1 also includes a set of members ensuring the rotation of said drum 2 during the deployment and folding of the deck.
- this drum 2 is mounted in free rotation on an axis 3, the latter being subdivided into two sections of axis 4, 5 located in the extension of one another and having salient relative to the ends 6, 7 of the drum 2.
- One of these sections of axis 4 is provided with elastic return means 8 whose function consists in substantially compensating for the weight of the deck when it is folded.
- elastic return means 8 also make it possible to control the deployment of said deck and avoid sudden fallout of the latter.
- these elastic return means 8 are formed, substantially, by a helical spring 9 engaged on the section of axis 4 and cooperating, simultaneously, with the latter and the drum 2.
- the roller shutter 1 comprises axial adjustment means 10, 101 of the drum 2 on each of the axis sections 4, 5, so as to vary the length of the projecting part 11, 12 of the latter by relative to the ends 6, 7 of said drum 2.
- the axial adjustment means 10 of the latter on the section of axis 4, provided with the return spring 9, are formed, on the one hand, of means 13 ensuring the mobility of said spring of reminder 9 on this section of axis 4.
- the means 13 consist of two sliders 14, 15 to which the ends 16, 17 of the return spring 9 are fixed.
- One 14 of these sliders is mounted sliding and immobile in rotation on the section of axis 4.
- the other slider 15 is made integral in rotation with the drum 2 and, simultaneously, mounted in free rotation on a bush 18 provided with a central bore 19 in which the section of axis 4 slides.
- the cursor 15 has a periphery 20 of polygonal shape cooperating with the internal walls 21 of the drum 2, the latter also being of polygonal section.
- the cursor 14 has, meanwhile, a diameter 22 substantially less than the circle inscribed in the polygonal section of said drum 2, so as to avoid its rotational drive by the latter.
- said cursor 14 comprises, in its center, a bore 23 of parallelepipedal section and of preferably square, adjusted to the section of the axis section 4, the latter being of identical shape.
- the sleeve 18 on which the cursor 15 is mounted, in free rotation, is also provided with such a bore 19 of square section in which the section of axis 4 can slide.
- the drum 2 rotates the slider 15 giving a torsion to the return spring 9, the latter being, in fact, connected, by its end 16, to the slider 14 blocked in rotation.
- said spring 9 tending to return to its initial rest position, exerts a restoring torque on the drum 2 and facilitates the winding of said apron on the latter.
- the axial adjustment means 10 of the drum 2 on the axis section 4 also include means 25 allowing the latter to slide in said drum 2.
- these means 25 are formed, substantially, by a sleeve 26 provided with a square section bore 27 in which the axis section 4 can slide.
- a tubular end piece 28 is mounted in free rotation on the sleeve 26, this tip 28 being embedded in the drum 2 at the end 6 of the latter.
- the sleeve 26 can be provided with locking means 29, for example a screw, making it possible to immobilize in translation the section of axis 4 relative to the drum 2.
- locking means 29 are not brought into their active position only after having inserted the projecting part 11 of the axis section 4 in its bearing and carried out the leveling of the roller shutter 1 with respect to the door, window or the like.
- the axial adjustment means 101 of the drum 2 on the axis section 5 are of reduced complexity, the latter being devoid of elastic return means.
- these axial adjustment means 101 are formed, on the one hand, by a hub 30 integral with the internal end 31 of said section of axis 5.
- a hub 30 integral with the internal end 31 of said section of axis 5.
- this hub 30 is mounted, free in rotation, a ring 32 of which the outer periphery 33, of polygonal shape, cooperates with the internal walls 21 of the drum 2.
- this ring 32 is, on the one hand, sliding in the latter and, on the other hand, integral in translation with the section of axis 5 thanks to the hub 30 comprising, at its ends, peripheral flanges 301 trapping the ring 32.
- the axial adjustment means 101 are also constituted by a tubular end piece 34 mounted on a bush 35 in which the section of the axis 5 slides, this end piece 34 being embedded in the end 7 of the drum 2 just like the tubular end piece 28 located at the opposite end 6.
- the sleeve 35 is able to include, like the sleeve 26 mentioned above, locking means 29 making it possible to immobilize the section of axis 5 relative to the drum 2.
- the roller shutter 1, according to the invention, also comprises a drive device 36, such as a winch or the like, actuated by control means (not shown) such as chain, strap, rod or electric motor for applying a rotation to the drum 2.
- control means such as chain, strap, rod or electric motor for applying a rotation to the drum 2.
- this drive device 36 is mounted on the axis section 5 and cooperates with the end 7 of the drum 2.
- the rolling shutter 1 comprises means 37 making it possible to position, without distinction, this driving device 36 at one or the other of the ends 6, 7 of the drum 2.
- these means 37 are formed, on the one hand, by a section of axis 5 of square section, identical to that of the section of axis 4 and, on the other hand, by means of axial and angular adjustment 38 of said drive device 36 relative to one or other of the ends 6, 7 of the drum 2.
- the axial and angular adjustment means 38 are formed by a flange 39 comprising, at its center, a tubular end piece 40 provided with a square section bore 41 adjusted to the section of the sections of axis 4 and 5.
- the tubular end piece 40 is further provided with locking means 42, for example a screw, allowing to immobilize the flange 39 axially with respect to one or the other of the sections of axis 4, 5.
- the flange 39 of these axial and angular adjustment means 38 comprises a series of perforations 43, these being arranged in a circle concentric with the axis of rotation 44 of the drum 2. These perforations 43 ensure the passage of a fixing member 45 cooperating with the drive device 36.
- the user firstly determines the location of the drive device 36 relative to the drum 2. He then provides the socket 26 or 35, located on the opposite side of the drive device 36, of blocking means 29. During the next step, the user inserts the projecting ends of the sections 4, 5 into their corresponding bearing and proceeds to center the roller shutter 1 with respect to said door or window. Then, it performs the tightening of the blocking means 29 of the sleeve 26 or 35 before properly applying the drive device 36 against the end 6 or 7 of the drum 2.
