Definitions

  • the present invention relates to a device for fastener for roll-up closure with curtain with fixed shaft, said fixing device being intended to join reversibly one of the ends of said shaft fixed to the frame of said closure winding.
  • the built term very generally means any support on which can be assembled the various parts constituting the closure. It can thus be, by example, a specific independent coaching or more directly from the edges of the opening to be blocked.
  • the invention finds an application particularly advantageous in the field of fixed shaft winding closures, equipped with anti-fall devices capable in each case of block the curtain lowering in the event of a failure of one of the elements of the winding mechanism.
  • the winding of the curtain is traditionally carried out around at least one coil mounted mobile in rotation around said fixed shaft.
  • Each coil is also connected to the fixed shaft by means of a spring balance type, wound inside even of said coil.
  • this elastic return means is responsible for counterbalancing at least partially the weight of the curtain, restoring energy during the opening phase stored as a couple during the closing.
  • the compensation spring is the most stressed and therefore the most fragile element of the system. This is why it is advantageous to couple each compensating spring with a fall prevention device likely to prevent the curtain from falling in the event breakage or simply shedding of said spring compensation.
  • part curtain remains wrapped around the different coils on the fixed shaft. This situation prohibits any direct intervention on the deficient compensation spring. Access to the coil can only be restored after dismantling the curtain, when it is not completely closed. The difficulty of the conditions of intervention makes everything extremely complicated, and therefore time-consuming troubleshooting and expensive.
  • the request EP 0 768 445 describes the use of a unlocking device allowing unwinding curtain manual after actuation of the fall prevention device, that is to say despite the solidarity of the faulty coil with fixed shaft.
  • the unlocking device is designed to release the rotation of the fixed shaft around its axis longitudinal. It is then enough to accompany manually the complete unfolding of the curtain to be able to easily access the faulty coil and proceed to change the compensation spring.
  • the unlocking device described in the prior art is composed of a sleeve non-circular section positioned at the end of the shaft, as well as a sheet metal support intended to be secured to the frame of the closure.
  • the support also includes two housings side by side and communicating with each other via their Respective upper openings.
  • the sleeve can thus be involved indifferently in one or the other dwellings with very different sections, since one is complementary to that of said sleeve and that the other is circular. So therefore, according to the slot in which it is inserted, the sleeve is blocked in rotation or mobile in rotation; the tree supporting the coils therefore respectively in normal operating position or in the unlocked position.
  • this unlocking device has serious drawbacks that are due as much to its structural complexity as difficulties in its implementation in action.
  • the support consists of a machined sheet metal part, relatively complex in shape and therefore costly to carry out.
  • the tree must also be arranged to receive the sleeve, which increases even more the overall cost of the device.
  • the implementation of this system is impractical since it is necessary to raise the curtain to change accommodation, and therefore to move from the position locked in the unlocked position. This imperative can even become crippling when the curtain presents high mass, as is the case in most cases.
  • the technical problem to be solved by the object of the present invention is to provide a fixing device for curtain with fixed shaft winding closure, intended to secure reversibly one end of said tree at frame of said roll-up closure, device for fixing which would avoid the problems of the state of the art by being of a low price of comes back, while being of an extremely implementation easy.
  • the device for fixing comprises support means suitable for immobilize the tree so that the position of its longitudinal axis is constant, as well as locking means capable of immobilizing the shaft in rotation with respect to its longitudinal axis.
  • the function of the support means is not completely immobilize the tree since it retains axial rotation mobility that only locking means are able to block.
  • the support means and the means of lock are perfectly complementary and that's their combined action which makes it possible to make the tree totally fixed.
  • the support provided by the support means is materializes by an absolute stability of the position of the longitudinal axis of the tree.
  • the tree is seen like this immobilized, both in radial translation by relative to its axis only in rotation with respect to an axis distinct from said longitudinal axis.
  • the causes the positioning of the longitudinal axis to be constant means that any displacement of the tree, other than an axial rotation, is not allowed.
  • the locking means are independent here support means in the sense that they are distinct, contrary to what we find in the system of the prior art previously described. Their function is to condemn the last mobility of which the tree remains provided when supported by the support means, that is to say the axial rotation on itself. Once the locking means used, the shaft is thus immobilized in rotation relative to its axis. Combined with that of the support means, the action of locking means contributes to achieving fixity complete of the tree.
  • the invention as thus defined presents the advantage of being extremely simple to set up artwork.
  • the fact that the locking means are independent from the support means allows indeed to pass indifferently from a so-called position locked, in which the shaft is completely fixed, in a so-called unlocked position, in which the shaft is movable in axial rotation. Contrary to what's going on in the prior art it's not here no question of manipulating the curtain to pass from one position to another.
  • the locking means are intended to block the axial rotation of the shaft reversibly. Also, it is particularly advantageous to mount them mobile in movement between a so-called engaged position, wherein said locking means are in able to immobilize the rotating shaft relative to its longitudinal axis, and a so-called disengaged position wherein said locking means are in the inability to achieve such immobilization.
  • the displacement of the locking means can be effected following any trajectory such as that corresponding to a translation, a rotation or a more or less complex combination of these two types of movements. The important thing is that the means of lock can be moved in one direction or in the other between the two extreme positions mentioned above.
  • the locking means are designed and arranged so that they can be operated from a place outside the space intended to be occupied by the curtain, and this whatever the level winding of the latter.
  • This feature simplifies the maximum the structure of the fixing device, in accordance with one of the essential objects of the invention which is to get the lowest cost possible. She consequently also increases the reliability of the system since a minimum of parts is required in this configuration.
  • the securing of the tree with the support means is carried out by inserting the locking means to both in at least one bore formed through said shaft and in at least one bore through said support means.
  • the blocking thus achieved allows to immobilize the shaft in axial rotation since the support means are integral with the frame of the roll closure.
  • Figure 1 is an exploded view showing the different components of a fixing device according to the invention.
  • Figure 2 illustrates the cooperation between different components of the fixing device shown in figure 1.
  • Figure 3 is a view of the device fixing of Figure 2, in a direction substantially opposite.
  • the fixing device 1 is intended to fasten the end reversibly 2 of a shaft 3, to the frame 4 of a winding closure 5 of fixed shaft type.
  • tree 3 carries a succession compensating coils 6 regularly spaced, around which a curtain 7 of flexible structure.
  • the frame 4 is here an integral part of the closure 5 since it is he who supports them different component parts, regardless of edges of the opening to condemn. He presents himself here in the form of flanges 8 coming to position orthogonally to each end of the shaft 3. So to be bolted or screwed to part of the structure defining the opening, each of these flanges 8 is provided with several fixing bores 9, 10 distributed over its entire surface. It is to highlight that each edge 11 extends in the plane of the slide, not shown, who is responsible for guiding unilaterally the translation of the curtain 7 along the opening. From this point of view, Figures 1 to 3 should be considered as rear views of the roll-up closure 5.
  • the fixing device 1 is provided with means for support 20 and locking means 40 including the combined action makes it possible to completely immobilize shaft 3, so that it is perfectly fixed during normal operation from closing to winding 5.
  • the means support 20 are able to prevent, on the one hand, any translation of the shaft 3 perpendicular to its axis longitudinal, and on the other hand, any rotation around an axis distinct from said longitudinal axis.
  • the rotation axial of shaft 3, only mobility not prohibited by the support means 20, is in turn controlled by the locking means 40 which, according to their position, are able or not to secure the end 2 of said tree 3 means support audits 20.
  • the support means 20 consist of a U-shaped piece 21 on which two abutment members are secured 22a, 22b presented here in the form of two bolts.
  • the role of the U-shaped part 21 and that of stop members 22a, 22b are perfectly complementary since they consist in ensuring keep in perpendicular directions one compared to each other. Their combined action allows thus immobilizing the axis of the shaft 3 in a constant position.
  • the part 21, forming a support is intended to be secured to frame 4 via its part central 23.
  • This is advantageously for this purpose provided with two through bores 24a, 24b, suitable for cooperate by blocking with two fixing screws 25a, 25b previously inserted in two lights rectangular 26a, 26b formed through the flange 8.
  • the part 21 Due to its U shape, the part 21 has two parallel fins 27a, 27b which extend horizontally, respectively above and below from the end 2 of the shaft 3, in order to maintain vertically said shaft 3. It is also provided many bores 28a, 28b, 29a, 29b, 30a, 30b, 31 whose usefulness and formal characteristics will described later.
  • the whole is completely symmetrical so that the U-piece 21 is perfectly reversible.
  • the two stop members 22a, 22b are arranged transversely between the two fins 27a, 27b, of on either side of their distal ends respective. Their position is such that they are then able to maintain horizontal support for the shaft 3 when the end 2 of it rests substantially in the center of the U-shaped part 21.
  • each stop member 22a, 22b consists of a screw 32a, 32b coming to engage in a first through bore 28a, 28b formed in one of the corners of the end distal of fin 27a, then in a second bore crossing 29a, 29b arranged identically in the corresponding corner of the distal end of the fin 27b, before coming to cooperate by screwing with a nut 33a, 33b.
  • the screws 32a, 32b and their respective nuts 33a, 33b are replaced by bent pins at their upper parts to be retained on the support 20 by its own inertia.
  • the joining of the U-shaped part 21 on the flange 8 begins with the installation of the fixing screw 25b. It is inserted successively in the rectangular light 26b and in the circular bore 24b, then cooperate by screwing with a nut 35b.
  • a positioning tab 34 arranged at the other end of the central part 23 relative to said attachment point. This positioning tab 34 is able to cooperate by interlocking with the other light rectangular 26a, thus immobilizing the part 21 in rotation around the screw 25b.
  • the end 2 of the shaft 3 can then be engaged without problem between the fins 27a, 27b, since neither the end of the screw 25a, nor the nut 35a, do not protrusions on the internal surface of the central part 23. Once this operation is completed, the second screw of 25a fixing can then be put in place and so supplement the action of the positioning tab 34.
  • the locking means 40 are constituted by a U 41 section pin circular, suitable for joining the end 2 of the shaft 3 to the support means 20.
  • its end active 42 is shaped so that it can cooperate by blocking, on the one hand, with two coaxial bores 30a, 30b formed respectively through each fin 27a, 27b of the U-shaped part 21, and on the other hand, with two equally coaxial bores 35 arranged at through end 2 of shaft 3 to allow an integration from side to side.
  • the distance between each bore 30a, 30b of the central part 23 corresponds substantially to that existing between each bore 35 and the distal end 36 of the shaft 3, so that all of these bores 30a, 30b, 35 are able to be collinearly aligned.
  • the oblong shape of bores 30a, 30b guarantees the existence of an axial clearance likely to facilitate coaxial positioning of different bores 30a, 30b, 35 and therefore the insertion of the active end 42 of the pin 41.
  • the locking means 40 are movable mounted moving between a position engaged and a disengaged position, in which said locking means 40 are respectively able and unable to immobilize the axial rotation of tree 3.
  • these two positions extremes correspond to the facts that the means of lock 40 are able or not to secure the end 2 of the shaft 3 to the support means 20.
  • the pin 41 is mounted movable in translation in a guide light 43 formed vertically through the flange 8, in the same plane that the oblong bores 30a, 30b carried by the fins 27a, 27b of the U-shaped piece 21.
  • the active part 42 is able to insert successively into the first oblong bore 30a, in the two circular bores 35, then in the second oblong bore 30b, thus achieving the locking in axial rotation of the shaft 3.
  • the height of the guide light 43 corresponds substantially at the length of the active end 42, so as to allow the perpendicular introduction of the pin 41 through the flange 8.
  • the means lock 40 can be operated from a position outside the susceptible space to be occupied by curtain 7, whatever the level winding of said curtain 7. This means that in the in this case, the displacement of the pin 41 cannot not be ordered from a localized point, no only in the space reserved for winding the curtain 7, but also inside said space.
  • the implementation of the means of locking 40 is carried out from outside the rolling closure 5, since the pin 41 is shaped so that its passive end 44 can be accessed at the external face 45 of the flange 8.
  • many other configurations equivalents can be adopted to allow this remote implementation of the blocking performed by locking means 40.
  • the two circular bores 31, 46 supported respectively by the U-piece 21 and by the flange 8, are intended to be positioned coaxially one relative to each other when the support means 20 are secured to the frame 4. They are then arranged to their turn substantially coaxially with respect to the hollow shaft 3, which allows the passage of the wires power supply and / or release cable in the case where the winding closure 5 has a motor central.
  • pin 41 The upward translation of the pin 41, directed at all times by the guide light 43, causes the progressive disengagement of the part active 42. This will indeed slide in the different bores with which it cooperates by blocking, and thus disengage successively from the oblong bore 30b, circular bores 35 and the oblong bore 30a. Once this operation finished, pin 41 is no longer able to prevent the axial rotation of the shaft 3. This one can then turn on itself and thus allow the unwinding of the curtain 7, which is preferably supported by the convenience store during all this maneuver.
