Definitions
- the present invention relates to a device for retainer for a roll-up closure with a flexible structure deck, suitable for being wrapped around a substantially cylindrical and mounted support system movable in rotation around a fixed shaft arranged generally above an opening to be condemned.
- the invention finds an application particularly advantageous, but not exclusive, in the area of vertical blanking closures equipping accesses to industrial buildings and commercial. We think here for example of curtains metallic garages or storefront grilles of shops.
- curtain or apron mean more generally any means capable of closing an opening, that is to say a plate, an assembly of blades, a grid, etc.
- the structural flexibility needed to the winding of this organ can come directly of the intrinsic nature of the material constituting it and / or joints connecting the different parts the component.
- the winding of the deck is traditionally carried out around at least one coil mounted mobile in rotation on 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 at least partially counterbalancing the weight of the deck, restoring during the phase energy stored as a couple during the closing phase.
- an apron has a relatively heavy important, generally ranging from several tens to several hundred kilograms. Combined with a high fall speed, this mass constitutes a real danger to users.
- French patent application 2,739,656 describes however several restraint systems likely to fulfill this function.
- the principle is the same for each mode of realization described. It basically consists of positively couple to the fixed shaft, the coil whose spring fails, after angular displacement given of said coil compared to means of specific locking. This movement, controlled by a return element mounted between the coil and the means lock, will then allow these means of interlock to control the movement of a piece of blocking to a fixed ratchet wheel forming a stop, thus achieving the immobilization of the apron relative to the shaft of the roll-up closure.
- the technical problem to be solved by the object of the present invention is to provide a retainer for roll-up closure with an apron capable of being wrapped around at minus a coil mounted movable in rotation around a fixed shaft, each voice coil being connected to the shaft fixed by means of a compensation spring spiral type, a retaining device being associated to each compensation spring in order to block the lowering of the bulkhead in the event of failure of said spring compensation; retainer that would allow avoid the problems of the state of the art by offering in particular great reliability as well as low cost compared to that of closing at secure, both in terms of the cost price of restraint proper as that of its adaptation to said closure.
- each compensation spring is integral a blocking element mounted movable on the move the corresponding coil, the blocking element being able to move towards a static organ integral with the fixed shaft in order to cooperate by blocking with a part forming a stop of said static member, said blocking element being kept away from the static organ by the restoring force exerted by the compensation spring.
- the invention as thus defined presents the advantage of being extremely simple in design since this security system does require the cooperation of only two pieces, namely one movable blocking element and a static member.
- the adaptation of such retainer requires only modifications minor at the level of the intrinsic structure of the roll closure. Indeed, these transformations are essentially limited to simply joining together the outer end of the balance spring a blocking element mounted movable on the move the corresponding coil. This in no way calls into question causes the classic closing mechanism, whether either from a structural and / or functional point of view. For all these reasons, the object restraint of the present invention enjoys reliability increased as well as a cost price particularly low compared to equivalent systems already known.
- the spring compensation is indeed the only commanding piece immobilization or displacement of the element of blocking with respect to the coil. In other words, it ensures only the immobilization of the blocking element in passive position, it also controls only the displacement towards the static organ, and finally it alone guarantees that it remains in the active position; the passive and active positions being those in which said blocking element and said member static are remote and contact respectively one of the other.
- the position of the locking element with respect to the static organ therefore depends only and above all directly from the state of the compensation spring.
- the spring compensation is stretched permanently due to a excess winding of the turn constituting it, and this whatever the position of the deck.
- the force of recall is only felt at its outer end. It is indeed the only one likely to move, for the double reason that it is united to the locking element mounted to move on the coil on the one hand, and that said coil is itself rotatably mounted around the fixed shaft on the other hand.
- the only return force thus allows advantageously hold the locking element in passive position, i.e. away from the organ static. This balance also remains perfectly stable as long as the compensation spring retains its original mechanical properties.
- the volume it occupies inside the coil is very much lower than the one it has at rest, that is to say when it is not subject to any winding stress. Also, after rupture, it will tend to naturally return to shape original. In case of failure, it occurs by therefore a substantially radial expansion of the compensation spring which tends to deviate as far as possible of the axis around which it was wound. This movement continues until spring deployment be stopped, due to the limited space existing at inside the coil.
- the element of blocking When it is no longer subjected to the restoring force exerted by the compensating spring, the element of blocking is therefore free to leave its position passive and move relative to the coil on which it is mounted movable towards the organ static. This obviously implies that he can be trained on the move through a moving organ. This is precisely what produced when the compensating spring breaks then comes alive with the double movement of radial extension and rotation previously described.
- the blocking element secured to the outer end of the spring compensation, is then moved to the position active in which it cooperates by blocking with the static organ.
- the locking element is kept in contact with the static organ thanks to the fact that the radial expansion of the compensation spring is limited by the low volume available inside the coil, and that said spring comes to block very quickly against the apron portion surrounding said coil, consequently immobilizing said blocking element.
- the retainer includes guide means able to direct movement of the blocking member towards the static organ, in case of rupture of the compensation spring; the planned displacement taking place between the passive position in which the blocking element is at a distance from the member static and the active position in which said blocking element is in contact with said member static.
- the compensation spring is animated by a complex movement resulting substantially from the combination of radial expansion and rotation in the winding direction of the coil. Also, it is particularly advantageous to control the moving its outer end so that the element movable blocking device is safely and safely steered effective towards the static organ.
- the goal is here above all to avoid the risks of catching the compensation spring and / or blocking element with any element, present inside the coil, other than the static member. Means of adequately arranged guides allow advantageously achieve this goal.
- At at least a portion of the blocking element has a flexible structure allowing it to deform and thus to temporarily disengage from the organ static when said blocking element is in active position.
- This advantageous feature allows the device to be temporarily unlocked detention. Unlocking can be performed manually or through a more mechanism or less complex.
- Figures 1 and 2 show, in section partial transverse, a retaining device according to a first embodiment of the invention.
- Figure 3 is a perspective view in section partial of the retainer illustrated in the figures 1 and 2.
- Figures 4 and 5 are sectional views transverse, illustrating a retaining device according to a second embodiment of the invention.
- closure 1 with vertical erasure illustrated in Figures 1 to 3 is of the fixed shaft type. So classic, it has a support system 2 around from which a sliding mounted apron 3 is wound up between vertical slides 4, 5.
- the support system 2 consists of a series of compensating coils 6 with spring such as that visible on FIGS. 1 to 3. Each of them is mounted mobile in rotation around the same fixed shaft 7, via bearings not shown.
- the coils 6 are further connected transversely to each other by two blades of reinforcement 8, 9, joined in opposition to the respective circumferences of said coils 6.
- the apron 3 is made up of a plurality of articulated blades; the one at the end upper being secured to the reinforcing blade 9 by screws 11.
- each coil compensator 6 is provided with a spiral spring 12 rolled up on itself between the two side flanges 13, 14.
- the inner end 15 of the spring 12 is all also conventionally secured to shaft 7 by means a fixing screw 16.
- its end external 17 is not directly attached to the coil 6 but secured to a blocking element 20 mounted movable in displacement on said coil 6, so as to what in case of failure of the compensation spring said blocking element 20 can cooperate by blocking with a static member 30 secured to the fixed shaft 7.
- guide 40 formed here by two oblong slots 41, 42 arranged opposite each other on the two flanges 13, 14 of the coil 6 and in a direction substantially tangential to the axis of rotation of said coil 6.
- the two long sides 43, 44 of each oblong light 41, 42 are able to cooperate by sliding with at least a portion of section 21 of the locking element 20.
- the so-called rear ends 45 and before 46 of each of these lights 41, 42 delimit the positions respectively passive and active of said blocking element 20 by relation to the static organ 30.
- the element of blocking 20 is composed of a bar 22 of section rectangular on which is fixed transversely a curved blade 23 forming a hook.
- This blade 23 constitutes the active part 24 of the blocking element 20 because it is she who is intended to cooperate by blocking with a part forming an abutment of the member static 30.
- the bar 22 plays a role while as essential when participating in guiding the blade 23 from the passive position to the active position. To this end, each of its ends is able to slide freely in one of the two lights 41, 42 whose height, i.e. the distance between the two long sides 43, 44, is complementary to the thickness of said strip 22 in order to guarantee the desired guidance accuracy.
- the active part 24 of the locking element 20 is arranged outside the coil 6 in order to come to position near a static organ 30 external.
- the organ static 30 consists of a fixed gear 31 on the fixed shaft 7 by means of screws 32, 33 or any other means of attachment.
- Each tooth 34 has here a triangular point profile whose edge 35, extending radially from the center of the wheel, advantageously constitutes a part forming stop of the static member 30.
- the static member 30 as well as the locking element 20 and the means of guide 40 are dimensioned and arranged so that that in passive and active positions, said organ static 30 and said blocking element 20 are respectively at a distance and in contact with one of the other.
- Figure 1 shows a retainer in which the locking element 20 is in the passive position.
- the latter is indeed immobilized at a distance of the static member 30 under the action of the spring of compensation 12, so that the coil 6 is suitable for freely rotate around the fixed shaft 7.
- the deck 3 can therefore be operated just as easily freely as long as the retainer does not come into operation.
- the immobilization of the locking element 20 in passive position comes from the causes the bar 22 to be held in abutment against the rear ends 45 of the guide lights 41, 42, by the restoring force exerted by the spring of compensation 12 of the hairspring type.
- the active part 24 of the locking element 20 extends vicinity of the periphery of the toothed wheel 31 but is in no way able to get in touch with any part 35 forming an abutment of the member static 30.
- the curved blade 23 forming a hook will sooner or later come cling to one of the many spaced 34 teeth regularly around the circumference of wheel 31. Once the end of the hook against the side 35 forming a stop for one of these teeth 34, the coil 6 to which the locking element 20 is secured is then stopped in its rotation so that the fall of the apron 3 is also stopped.
- the locking element 20 is thus found in active position as shown explicitly in the figure 2.
- the bar 22 is held in abutment against the front ends 46 of the guide lights 41, 42 in due to the fact that the compensation spring 12, to which it is attached, is itself immobilized at inside the coil 6. Indeed, like its radial expansion is limited due to lack of space sufficient, the compensating spring 12 goes through therefore exert such pressure, against the portion of the deck 3 surrounding the coil 6, that it will somehow get stuck and therefore unable to move.
- the active part 24 of the locking element 20 is advantageously provided with a flexible structure allowing to deform. So although one of his ends is fixed since secured to the bar 22 perfectly still at this particular moment, its other end 25 called free is able to deviate from or be removed from the static member 30 to allow any rotation of the coil and thus unlocking the retainer. he is then theoretically possible to raise or lower the apron 3.
- the triangular profile of the teeth 34 formed on the periphery of the wheel 31 is such as to offer only an edge 35 forming a stop, that is to say one extending radially from the center of said toothed wheel 31.
- the other edge being bevelled, it is unable to cooperate by blocking with the active part 24 of the locking element 20.
- the rotation of the coil 6 cannot be stopped only in one direction: that corresponding precisely when the deck 3 falls.
- the locking element 20 has a structure flexible enough to allow it to deform.
- the active part 24 of the locking element 20 is advantageously constituted by a leaf spring. Flexibility natural element will allow its end free 25 to follow the contour of the toothed wheel 31, in traversing the succession of broken lines that constitutes the series of triangular teeth 34. As the free end 25 will only meet in this direction no roughness forming a stop, nothing will prevent the rotation of the coil 6 with respect to the static member 30.
- the coil 6 will then come to a standstill at first, then turn very slightly in the direction of unwinding until the free end 25 of the blade 23 bears against the edge 35 forming a stop one of the teeth 34 of the wheel 31. The apron 3 is then again blocked despite its own weight which tends to make it fall.
- a blocking element 50 mobile able to cooperate by blocking with a member static 60 fixed.
- the outer end 17 of the compensation spring 12 is integral with the element blocking 50 so as to be kept away from the static member 60 when said spring of compensation 12 is in perfect working order.
- movement of the locking element 50 in the direction of the static member 60 is advantageously provided by guide means 70 consisting of two lights oblong 71 arranged opposite on the two flanges 81 of the coil 80.
- the blocking element 50 here consists only of a simple bar 51 movable mounted moving through the coil 80, moreover in a substantially radial direction relative to the center of said coil 80.
- the means of guide 70 are indeed oriented either tangentially but radially.
- Static organ 60 is also different since it comes under the shape of a crown 61 with teeth interior.
- the spring compensation 12 is conventionally wound on itself between the flanges 81 of the coil 80. Its ends internal 15 and external 17 are joined respectively to the fixed shaft 7 and to the element of blocking 50. Subject to significant restoring force exerted by the compensating spring 12, the element of blocking 50 is pressed against the rear ends 72 guide lights 71 so it's out of contact of the crown gear 61.
- the coil 80 is by therefore able to rotate around the fixed shaft 7 in order to raise or lower the apron 3.
- the blocking bar 51 has a length much greater than the thickness of the coil 80 and that most of this surplus is spread perpendicular to the plane in which the toothed crown 61, said bar 51 itself comes in contact with said crown 61 when the position passive is reached.
- the blocking is then carried out similar to the first embodiment previously described, so that the fall of the deck 3 is still there.
- the bar 51 engages first place between two consecutive teeth 62.
- the bar 51 will slide along the beveled edge 64 of one of the teeth 62, edge 64 with which she stays perfectly in contact under the action of the compensation spring 12. This relative displacement ends when the bar 51 comes into abutment against the radial edge 63 of the other tooth 62, making thus blocking.
- the blocking element 50 is capable of deform and therefore it presents a flexible structure. Only the specific shape of the teeth 62 formed on the crown 61 appears essential, in combination with the radial mobility of the bar 51.
- each tooth 62 in fact allows the crown 61 to not have no part forming a stop when the coil 80 is rotated in the winding direction.
- the locking element 50 is potentially able to be moved back if we exerts on it a sufficient push, that is to say of intensity greater than the voltage generated by the compensation spring 12.
- the bar 51 will be able to slide along from each beveled edge 64 while moving away radially towards the center of the coil 80. A once this operation is completed, the bar 51 can to abut against the radial edge 63 of one of the teeth 62 in order to again lock the fall of the apron 3.
- the invention is not limited to particular embodiments which have been described in title of preferred examples. It also includes all variants remaining within the scope of the patent.
- the blocking element can be a simple bar or a more complex organ i.e. composed for example of a first part ensuring the guidance and a second part carrying out the blocking.
