Definitions

  • the invention relates to a device forming a support. end for a winding shaft in a trunk of a closing or sun protection installation.
  • the invention also relates to an operating mechanism of such installation.
  • closing installation means the doors, the gates, shutters and equivalent equipment.
  • Such a safe is sealed in place projecting laterally from the opening of which it forms the lintel.
  • the trunk is closed laterally either by masonry or by a console end, for example plastic.
  • supports for an axis winding of an apron for selective closure of the opening.
  • the trunk has a longer length at the width of the opening, the distance between the ends of the trunk is greater than the length of the hole provided in the lower part of this chest for the introduction of the winding shaft. Therefore, it is not always possible to insert a length tube into the trunk substantially equal to that of the trunk. So it is necessary to compensate for the difference in length between the wall and the chest.
  • This compensation can be achieved by equipping the tree a telescopic tip.
  • a nozzle which must be housed in the tree which is then tubular, is not very rigid, in especially when relatively large deviations have to be compensated, so that the geometric stability of the winding mechanism can be questioned.
  • FR-A-2 229 851 also teaches to provide a telescopic support mounted through an end console of a tunnel safe. This construction remains fragile and difficult use when a reservation must be provided in masonry for housing part of the device outside the trunk.
  • the invention relates to a device of the aforementioned type which comprises a main support capable of being immobilized relative to the trunk, characterized in that it further comprises at least a first set overall cylindrical defining a receiving volume, either of element integral with the winding shaft, or a second overall cylindrical assembly, this first assembly being formed of a sleeve capable of sliding axially in a bore the main support and a ring fitted with at least one latching tab on the sleeve, this tab being provided a rack capable of cooperating with a relief of the support for immobilization in translation of the first assembly generally cylindrical in this bore.
  • the overall cylindrical assembly can slide axially with respect to the fixed support then that it supports, directly or indirectly, one end of the winding shaft.
  • the rack allows effective immobilization of this assembly in translation when an adjustment of the axial position of the assembly has been performed.
  • the invention also relates to an operating mechanism a locking or sun protection system which includes a device as previously described.
  • Such mechanism is simpler to install and more reliable than those state of the art, including when the tunnel safe has a length appreciably greater than the width of the opening to be closed.
  • the device shown in the figures comprises a support 1 intended to be fixed on an end console 2 a tunnel chest 3 shown in phantom.
  • the support 1 is intended to be immobilized by cooperation of shapes on the console 2.
  • the support 1 comprises a base plate 11 from which extends a generally cylindrical part 12 of which we note X-X 'the main axis.
  • part 12 extends from the plate 11 towards the inside of the boot 3.
  • the central bore 13 of the part 12 is traversing in the sense that it emerges from the plate 11 forward and backward thereof.
  • the internal radial surface 14 of part 12 is generally cylindrical and provided with two grooves 15 and 15 'substantially parallel to the axis XX ', these grooves extending to level of facing surfaces 17 and 17 'of two projections 18 and 18 'provided to enter housing 28 and 28' of console 2.
  • the grooves 15 and 15 ' are each limited by a stop, only one of which is visible in the figures with the reference 15 a .
  • the grooves 15 and 15 ' are diametrically opposite with respect to the axis XX'.
  • Grooves 19 and 19 ' are provided in the surface 14 with an angular orientation different from that of the grooves 15 and 15 '. These grooves 19 and 19 ′ extend over the entire length of the surface 14 parallel to the axis XX ′, that is to say in particular up to the front edge 12 a of the part 12.
  • the outer surface 41 of the sleeve 4 is generally cylindrical and forms two grooves 42 and 42 'extending over the entire length of the sleeve 4.
  • the sleeve 4 is provided with two heels 43 and 43' adjoining a rear edge 44 of the sleeve 4.
  • the heels 43 and 43 ' are dimensioned to slide in the grooves 15 and 15 'when the sleeve 4 is received in the bore 13, the movement of the sleeve 4 towards the front of the support 1 being limited by the cooperation of the heels 43 and 43' with the stops 15 a and equivalent.
  • the sleeve can only be introduced into the bore from the rear, as shown by the arrows F 1 .
  • the ring 5 has a diameter d 5 greater than the diameter d 13 of the bore 13, so that it can be pressed against the edge 12 a without penetrating inside the part 12.
  • These lugs are each provided with a nose or spout 52 has detent , 52 'is provided to be engaged in a recess formed near the rear edge 44 of the sleeve 4 and of which only one appears on the figures with the reference 45.
  • the ring 5 is made in a single piece of plastic and the flexibility of the legs 52 and 52 'allows a slight radial expansion of these legs when they are engaged in the grooves 42 and 42' in the direction of the arrows F 2 , the nozzles 52 a and 52 ′ a allowing the ring to be locked on the sleeve 4 engaged in the bore 13.
  • the support of the part 53 against the edge 12a of the part 12 makes it possible to limit the movement of the assembly A towards the rear of the support 1 when this assembly A has been formed.
  • the width l 42 of the grooves 42 and 42 ' is substantially equal to twice the width l 52 of the legs 52 and 52', so that the ring 5 can rotate around the axis XX 'while the sleeve 4 is immobilized in rotation about this axis by the cooperation of the heels 43 and 43 'with the longitudinal edges of the grooves 15 and 15'.
  • the width l 19 of the grooves 19 and 19 ' is slightly greater than that of the legs 52 and 52', the legs 52 and 52 'being introduced into the grooves 19 and 19' during their positioning movement on the sleeve 4 to inside the bore 13.
  • a translational movement of the assembly A along the axis XX 'inside the bore 13 possible, this movement being limited forwardly by support stubs 43 and 43 'against the abutments 15 a and equivalent and backward by the support part 53 on the edge 12 a.
  • This axial translational movement makes it possible to adjust the positioning of the interior volume of the sleeve 4 relative to console 2, which allows, for example, to receive the end of a roller shutter winding shaft.
  • this assembly is immobilized along this axis by rotating the ring 5 in the direction of the arrow F 3 , this which has the effect of bringing the legs 52 and 52 'opposite two teeth 12 b and 12' b formed on the surface 14, inside the front edge 12 a of the part 12.
  • the teeth 12 b and 12 ' b have a geometry allowing them to be inserted between two successive teeth of racks 52 b and 52' b provided on the external radial surfaces of the legs 52 and 52 '.
  • a second assembly B is formed by a second sleeve 104 and a second ring 105 which have the same functions that sleeves 4 and 5 and have smaller diameters their allowing to be received inside a central bore 63 sleeve 4.
  • the internal surface 64 of the sleeve 4 is provided with two grooves, only one of which appears in FIGS. 1 and 2 with the reference 65, delimited by a stop, only one of which appears in the figures with the reference 65 a , near the front edge 62 a of the sleeve 4.
  • Grooves 69 and 69 ′ are angularly offset relative to the grooves 65 and the like and extend over the entire length of the sleeve 4.
  • the outer surface 141 of the sleeve 104 is provided with grooves 142 and 142 'extending over the entire length of the sleeve 104 while two heels 143 and 143 'are provided nearby from its rear edge 144, the grooves 142 and 142 'being bordered, on the side of edge 144, by recesses, of which only one is shown with reference 145.
  • the ring 105 comprises two tabs 152 and 152 'each provided with a latching nose 152 a, 152' is intended to cooperate with one of the recesses 145 or equivalent.
  • the outer surface of each leg 152 or 152 ' is provided with a rack 152 b or 152' b intended to cooperate with a tooth 62 b or 62 ' b provided inside the front edge 62 a of the sleeve 4.
  • a part annular 153 of the ring 105 is provided to bear against the front edge 62 a of the sleeve 4.
  • the sleeve 104 is introduced into the central bore 63 of the sleeve 4 from the rear as represented by the arrows F ′ 1 while the ring 105 is snapped onto the sleeve 104 by the front of the support 1 as represented by arrows F ' 2 .
  • the grooves 142 and 142 ' are wider than the legs 152 and 152', so that the ring 105 can rotate around the axis XX 'while the sleeve 104 is immobilized in rotation inside the 'bore 63.
  • the legs 152 and 152' remain in the grooves 69 and 69 ', the limited translational movement of the assembly B in the assembly A remains possible, which allows an adjustment of the axial position of the 'assembly B with respect to assembly A.
  • the assemblies A and B can be deployed outside of the support 1 and extend over a relatively long length L 1 as shown in FIG. 4 or, on the contrary , inserted respectively inside the bores 13 and 63 and extend over a minimum length L 2 , as shown in FIG. 5.

  • the annular parts 53 and 153 can be equipped with arrow-shaped marks F 3 , F 4 , F ' 3 , F' 4 allowing an operator to easily identify the possible directions of movement, the arrows F 3 and F ' 3 corresponding to a blocking, that is to say bringing the racks into engagement with the immobilizing teeth while the arrows F 4 and F ' 4 correspond to a reverse movement in which the legs 52 and 52' or 152 and 152 'are brought back to the gorges 19 and 19' or 69 and 69 '.
  • a statement such as "BLOCKED” may be affixed next to the arrows F 3 and F ' 3 while a statement such as "OPEN” or “UNLOCKED” may be affixed next to the arrows F 4 and F ' 4 .
  • the device of the invention has the additional advantage that the adjustment of the axial position of the assemblies A and B is reversible, in the sense that it can be adjusted by means of several successive operations by a simple movement of the rings 5 and / or 105 in the direction of arrows F 4 and F ' 4 then again in the direction of arrows F 3 and F' 3 when a satisfactory length has been reached.
  • the device can understand only one set of the type of set A, the shaft 8 being received directly in the bore 63.
  • This variant of the invention is simpler than that shown in the figures but the variation in lengths which may be obtained is less important.
  • the device of the invention comprises more than two sets of the type of sets A and B, for example three or four sets, the accessible adjustment range then being increased Consequently.
  • the diameter of the part cylindrical 12 of the support 1 must be increased.
  • Figure 3 is a schematic representation which does not does not correspond to a mounting step of the invention because sets A and B are formed inside bores 13 and 63, the sleeves being introduced by the back of the base plate 11 while the rings are placed on the sleeves from the front of this plate.
