Definitions

• the present invention relates to an abutment, intended for a roller shutter installed in a building opening or the like, which flap comprises an articulated blade apron, suitable for unfolding in the opening and to be wound in a trunk at the edge of the opening. opening, said stop being provided to be fixed in a hole on a deck board, usually one of the last deck blades.
• the roller shutters often have on the final blade two projecting stops to stop the shutter apron under the lintel or under the trunk so that it does not fit completely into the box.
• Known stops today are fixed through the final blade, for example, using one or more screws.
• the fixing solution by screwing through the final blade has the disadvantage of requiring different lengths of screws depending on the different blade thicknesses. Aesthetically speaking, one may also wish to obtain a better quality because the screws or the washers and / or planks remain visible on the opposite side to the stop, that is to say in the view of the user through the glass once the shutter down.
• FR 2 836 511 proposes a partial solution to the problems raised above by presenting a quick-mounting stop for shutters, comprising two elements to be screwed to each other.
• the number of pieces is limited here but said elements, independent of each other, always require a certain dexterity of the technician.
• one of the elements is provided to completely cross the thickness of the blade of the flap on which the stop must be fixed, by an opening opening on both sides of the blade. This assembly always requires working blind on both sides of the shutter blade and monopolizing the two hands of the technician.
• the present invention aims to provide a stop for a roller shutter, which overcomes many of the disadvantages described above.
• An abutment for a shutter installed in a building opening or the like which flap comprises an articulated leaf apron adapted to unfold in the opening and to be wound in a trunk at the edge of the opening, stop being designed to be fixed in a hole formed on a deck blade, generally one of the last blades of the deck, according to the invention, is characterized in that it comprises two preassembled elements, namely:
• this first element comprising:
• a latching means comprising a projection formed on at least a portion of the end of said first member intended to cooperate with said hole, this projection being resiliently retractable to cross the edge of the hole and to return to the latching position,
• a second element comprising:
• the first connecting means may be a thread and the complementary connection means may be a tapping provided respectively on the two elements.
• the connecting means are advantageously provided to prevent separation of the two elements after a first screwing.
• Thread and tapping may have complementary stop lugs to prevent the complete unscrewing of said two elements relative to each other.
• Said polygonal shape may be rectangular or square.
• the first element comprises, on its outer surface, a thread and the polygonal head comprises a median slot so as to form two resiliently closeable blades, a projection forming a detent means being provided on the outer face of each blade.
• the second element advantageously comprises a sleeve in which there is provided a thread adapted to cooperate with the threading of the first element and the own locking means to cooperate with the latching means is constituted by a finger coaxial with the sleeve and provided to prevent the transverse elastic deletion of the locking means at the end of the assembly stroke of the two elements.
• At least the first element can be made of a material having both properties of pressure elasticity and tensile and torsional rigidity.
• the present invention also relates to a roller shutter comprising an articulated leaf apron characterized in that it is equipped with at least one stop as defined above.
• the rolling shutter may comprise hollow blades with two walls, one outside and the other inside, and according to the invention, said fixing hole of the stop may be formed only in the thickness of the outer blade of said shutter.
• the present invention finally relates to a method of installing a shutter stopper as defined above, according to which:
• a polygonal hole of shape corresponding to that of the detent means of the first element is practiced in the final blade of the shutter; the two elements are unscrewed to the end of the stroke, without separating them,
• the snap-in means of the first element are introduced into the hole by elastic pressure
• the second element is screwed on the first element until the second element abuts on said blade.
• the method of implementation of the abutment according to the invention requires the intervention of the operator only the outer side of said flap.

• a stop 1 intended for a shutter 2 installed in a building opening 3 or equivalent, which component 2 comprises an apron with blades 4 hinged together, adapted to unfold in the opening 3 and to wind in a box 5 at the edge of the opening 3.
• the stop 1 is intended to be fixed in a hole 6 formed on a blade 4 of the deck, usually one of the last deck blades.
• the abutment 1 according to the invention comprises two pre-assembled elements, namely:
• a first element 7 which has a latching means 8 in the hole 6 of the apron and a first connecting means 9,
• a second element 10 which comprises a connecting means 11 complementary to the first connecting means to allow pre-assembly of the two elements 7, 10, and a locking means 12 adapted to cooperate with the latching means 8 to prevent unlocking of this latching means 8 relative to the deck, when the assembly of the two elements is achieved.
• the assembly is such that the mounting and fixing said abutment 1 require access to only one side of the deck.
• the latching means 8 comprises a projection 13 formed on at least a portion of the end of the first element 7 intended to cooperate with the hole 6.
• the projection 13 is elastically retractable to cross the edge of the hole 6 and to return to position hooking.
• the first connecting means 9 is a thread 9a and the complementary connecting means 11 is a thread 11a respectively provided on the two elements 7, 10.
• the connecting means 9, 11 are provided to allow relative movement of said two elements 7, 10 connected to each other.
• the connecting means 9, 11 are provided to prevent separation of the two elements 7, 10 and more precisely to prevent separation of the two elements 7, 10 after a first assembly.
• the thread 9a may include a stop lug to prevent the complete unscrewing of said two elements 7, 10 relative to each other, after a first screwing.
• the latching means 8 of said first element 7 has a polygonal shape to cooperate with the hole 6 of similar shape and prevent a relative rotation between the first element 7 and the apron blade 4.
• This polygonal shape is advantageously rectangular as shown in Figures 3 and 4, or square.
• FIGS. 4 to 7 show a preferred embodiment of the stop for roller shutter.
• the first element 7 is hollow, of generally cylindrical shape and has on its outer surface the thread 9a extended by a polygonal head 8a, with a median slot 8b so as to form two blades 8c and 8d which can be brought together elastically, the projection 13 being provided on the outer face of each blade.

• the free end of the finger 15 is then set back blades 8c and 8d which can bend towards each other, since the slot 8b is free.
• the abutment thus put in place can therefore be considered as one-piece, in particular when a stop device opposes the complete separation of the two pre-assembled elements of the abutment.
• Such an arrangement in particular avoids the risk of falling or loss of parts during handling.
• the abutment according to the invention may be fixed only on the outer wall of a final shutter blade, hollow at least two parallel walls, as shown in Figure 7 .
• the screw-nut system as applied to the constituent elements of the abutment according to the invention therefore allows easy assembly and disassembly.
