  The present invention relates to a box outlet device, in particular a device for outputting a casing, particularly for maintaining a handling crank of a rolling shutter and control member equipped with such a housing output device. intended for maintaining a crank for operating a roller shutter.

  The invention also relates to a control member equipped with such a box outlet device.

  Although particularly intended to allow the maintenance of a roller shutter maneuvering crank, the box outlet device may also be used in other applications and in particular constitute a casing outlet allowing the passage of a winch or a strap connected to a retractor.

  Different types of box outlet have already been proposed and are marketed on the market.

  The main purpose of the box outputs intended to hold the operating crank is to provide the connection between the rolling shutter deck winder and the rolling shutter operating crank.

  In this application for which the invention is particularly intended, there is provided at the outlet of the box a ball joint, a control rod secured to the ball and passing through the box-pass, the assembly being connected to the operating crank.

  According to a first known embodiment, the introduction of the passecaisson is done by opening in the bottom of the box and coming fix a ball bearing on the outside, the fixing being made by screwing the bearing on the outer wall of the box, said bearing can accommodate the ball or the like.

  This type of caisson has various disadvantages and in particular demand to achieve, during the establishment of the box, several openings in the wall of the box; In practice, given the lack of precision in the realization of the holes, the connecting rod of the drum is not necessarily aligned with the barrel of the drum provided to cooperate with the rod.

  In addition, given the force exerted on the ball during operation of the operating crank and the transmission of this force on the landing, there is a risk of tearing screws out of the box.

  Furthermore, the operations of removal of the actuating rod are difficult to achieve given that it is generally necessary to work at height and remove all screws.

  Finally, the box-pass being disposed below the underside of the box with visible screws, it is very unattractive.

  There is also known a second type of box-pass device comprising two elements sandwiching the bottom wall of the box and connected together by a connecting element such as a screw.

  This type of known device has various drawbacks and in particular, requires a connecting rod which will necessarily be removed in case of removal of the box outlet and replaced by another for a new pose, in this type of device, the installation and removal can only be operated by a specialized installer.

  The present invention aims to overcome the disadvantages of the aforementioned techniques and to propose for this purpose a box outlet device whose installation and removal can be performed easily.

  Another object of the present invention is to provide a box outlet device in which the visible part, that is to say located outside the box, is reduced.

  Another object of the present invention is to provide a box outlet device that can be fixed indifferently on the underside of the box or on a cheek of the box or at the interface between the underside and the cheek of the box.

  Another object of the present invention is to provide a control member comprising the box outlet device, a control rod and a ball joint with a rod that does not need to be removed during installation and removal of the outlet. of caisson.

  The invention thus relates to a box outlet device, in particular for maintaining a roller shutter maneuvering crank comprising two elements, a first element secured to the box and a second element adapted to be secured to the first.

  According to the invention, the two elements comprise securing means for laying the second element on the first by a translational movement and the removal by a rotational movement and then translation.

  The invention also relates to a control member comprising a control rod, a ball and a box outlet device as mentioned above.

  Other features and advantages of the invention will appear more clearly on reading the following description of a preferred embodiment, in which the description is given by way of non-limiting example and in reference to the accompanying drawings, in which: - Figure 1 shows a perspective view of a first embodiment of the device according to the invention, disposed in a shutter box partially shown; FIGS. 2A and 2B show the detail, denoted A in FIG. 1, in enlarged view in two different positions; 3 shows a second embodiment of the device according to the invention, also shown in a partial perspective view of a shutter box; Figures 4A and 4B show an enlarged detail denoted A 'of Figure 3 in two different positions; FIGS. 5A and 5B show an exemplary embodiment in two positions of the second element of the box outlet device; Figures 6 and 7 show an exploded and compact view respectively of different elements of the control member; Figure 8 shows, in sectional view, a third embodiment of a box outlet device according to the invention.

  Referring mainly to FIGS. 2 and 4, there is shown a box 1 outlet device comprising two elements, a first element 2 integral with the box 5 and a second element 3 adapted to be secured to the first element 2.

  As represented in FIGS. 2 and 4, the two elements 2 and 3 comprise securing means 4 enabling the second element 3 to be placed on the first element 2 or, if appropriate, its removal.

  Figures 1 and 2, on the one hand, and Figures 3 and 4, on the other hand, show two different embodiments of the first integral member 2; however, in these two modes, the laying and removal operations of the second element 3 are identical, namely for laying, a translational movement and for removal, a rotational movement and then translation.

  The securing means 4 are arranged on the two elements 2, 3 and in particular comprise clips 7 arranged on one of the two elements 2, 3 cooperating with retaining means 6 arranged on the other element.

  In Figures 1 to 7, the clips 7 are arranged on the element 2; this arrangement is advantageous and in particular during the insertion phase of the clips 7 in the retaining means 6.

  However, it will be possible, as shown in FIG. 8, to reverse the arrangement of the securing means 4 by arranging the clips 7 on the element 2 secured to the casing 5 and the retaining means 6 on the second element 3 capable of being secured.

  Referring this time mainly to FIGS. 1, 2A and 2B, it can be seen that in this first embodiment, the second element 3 comprises clips 7 and the first element 2 retaining means 6 having an opening 8.

  This opening 8 has a dimension, called minimum, less than the spacing between the outer edges of the clips 7, which are in the example illustrated in Figures 1, 2A and 2B to the number of two, and allow the introduction by simple translation of element 3 inside element 2.

  At this level, it is interesting to note that the clips 7 are made in such a way that, when they are introduced into the opening 8, they bend slightly inwards and then once they pass the opening 8, return to their initial position preventing translation in the other direction, the lower flanges 9 of the clips 7 abiding against the retaining means 6. This position is shown in Figure 2B.

  The opening 8 also comprises a dimension, said maximum, this time greater than said spacing and allowing the removal of the second element 3.

  In the example of FIG. 2A, the clips 7 are arranged according to this so-called maximum dimension and which allows a translation of the element 3 allowing a release of this element with respect to the element 2.

  During the introduction of the second element 3 into the first element 2, the clips 7 are placed in the so-called minimum dimension, and pressure is exerted on the second element 3 until the clips 7 are introduced into the opening 8 and as shown in Figure 2B.

  For removal, a simple translation is not possible, the lower edges 9 of the clips 7 abutting against the retaining means 6 and therefore, it is necessary in a first step to rotate the second element 3 of in order to make the clips 7 coincide with the so-called maximum dimension and as represented in FIG. 2A.

  Then, it suffices for the operator to pull on this element 3 to remove the element 3 from the first element 2.

  To facilitate these operations, provision can be made, according to a first advantageous characteristic, for locating means 18 for setting up or removing the second element 3.

  These locating means may in particular consist of a visual indication made on the visible part of the second element 3.

  Furthermore, according to another advantageous characteristic of the invention, it is provided that the base 10 of the second element 3 resting on the casing 5 constitutes a gripping means allowing rotation by a suitable tool, for example by key or manually, of this element 3.

  FIG. 5 thus shows the base 10 of the second element 3 comprising two rounded ends connected by two flat parts and which can be clamped by a conventional flat key.

  Of course, depending on the number of clips 7 or even the positions of the maximum and minimum dimensions, it will be possible to envisage different angles of rotation necessary to pass from the laying position to the removal position of the second element 3.

  That said, according to an advantageous characteristic of the invention, it is expected that the rotational movement necessary for the removal of the second element 3 is of the order of 90.

  As indicated above, this box output device 1 will be particularly intended for maintaining a maneuvering crank.

  The implementation of the crank may, by friction, exert a torque on the element 3 which could pass unintentionally from its laying position to its removal position.

  To avoid this drawback, according to an advantageous characteristic of the invention, there is provided locking means 11 of the rotation of the second element 3 relative to the first element 2 during the implementation of the crank.

  Advantageously, these locking means 11 comprise at least one notch 12 on one of the two elements 2,3 cooperating with a groove disposed on the other element, the assembly making it possible to constitute a zone of friction greater than the rotational torque exerted on the second element 3 during the rotation of the operating crank.

  Preferably, the groove is provided at the element 2 and the notch 12 at the base 10 of the second element 3, as shown in Figure 5B.

  It should also be noted that in this use of the outlet device of the casing 1 for maintaining a rolling shutter crank, provision is made for the second element 3 to comprise means for receiving a ball joint.

  In this respect, it will be possible to use reception means 13 already used and known to the person skilled in the art in the case-by-case devices available on the market.

  In this regard, we see an example of a ball joint in Figures 6 and 7 showing a control member 14 comprising a control rod 15, a ball joint 16 and the second element 3 of the box outlet device 1.

  It is also important to point out at this level that one of the interests of the box output device 1 presented is that during the installation and / or the removal of box outlet 1, it is not necessary to disassemble the various elements shown in Figures 6 and 7, the assembly can be removed or placed on the first element 2 simultaneously.

  Thus, to carry out the laying and removal, it is not necessary to have a control rod that can be removed before the removal of the element 3 as was the case in particular in double-chambered caisson devices as described in the state of the art of the present application.

  Therefore, this box outlet device 1 greatly facilitates the assembly and disassembly operations of the entire box.

  Referring this time mainly to FIGS. 3 and 4, we see a second embodiment of the first element 2.

  In this second embodiment, the retaining means 6 comprise at least two stops 19, the space between these stops 19 being less than the spacing between the outer edges of the clips 7 of the second element 3 allowing its subjection.

  For the removal of the second element 3, this element 3 is rotated so that the clips 7 are pushed back by the walls 17, whose spacing is smaller than the space between the edges of the clips, and then a translation by exerting a traction on this second element 3.

  This example has at least two stops 19, the space between the abutments 19 being less than the spacing between the edges of the clips 7 of the second element allowing its subjection and walls 17 for uncoupling the second element 3.

  Of course, the second element 3 being identical to that proposed in the first embodiment, the advantageous embodiments of this element 3 as described in the first embodiment are also transferable in this second embodiment and in particular in Regarding the marking means 18 or the locking means 11 for rotating the second element relative to the first or the gripping means 10 for rotating the clips 7 of the second element 3.

  It should also be noted that, given the structure of the box outlet device 1, it is possible to have the first element 2 either at the lower face of the box 5, or at the cheek of said box or still at the interface between this lower face and said cheek of the box.

  The invention also relates to the control unit assembly 14 comprising the control rod 15, the ball 16 and the box outlet device 1.

  It also relates to a control member comprising a reel, a strap and a box outlet device 1.

  Of course, other embodiments within the reach of those skilled in the art could also be envisaged without departing from the scope of the invention defined by the claims below.
