  TOURNIQUET SHUTTER STOP AND ADJUSTABLE STOP

COMPOSITE MATERIAL.

  The object of the invention relates to the technical sector of the building and more particularly accessories for swing shutters. Different types of shutter stops are known in the open position in facades. In particular, turnstile devices which consist of a rod of which one end is shaped to be screwed or sealed in a wall, while the other bent end receives pivotally a blocking piece commonly called "sage leaf" intended to remember the or

  the shutter elements folded down on the front.

  In certain embodiments in metal, in composite or mixed material (metal-composite material), the rod receives with controlled sliding an adjustable stop and locked by screw against which the shutter bears, thus avoiding, by

  combination with the turnstile, the flapping of the shutter under the effect of the wind.

  According to another embodiment, the flap stop is adjustable in position by a screw-nut assembly, the screw being formed on the rod, the nut being arranged

on the stop.

  These embodiments have drawbacks in particular in terms of the cost of manufacturing the rod and its reliability, which must have a fine pitch thread, therefore fragile in the case of adjustment by screw-nut, or else grooves for orientation of the stopper and following locking screw only

  a generator in the case of sliding adjustment.

  On the other hand, given the maneuvers not always bear shutters, especially when they are double (French windows), repeated shocks occur.

  produce, shocks harmful to the longevity of shutters and shutter stops.

  Finally, the adjustment in position of the stop, in particular by screw-nut does not always allow to obtain the appropriate spacing between the turnstile and f J

  the stop which must be oriented substantially like the turnstile when the latter is in the blocking position of the flap (s), which does not allow

  keep the flaps folded down on the front without play.

  It is therefore to remedy these drawbacks that the shutter stop according to the invention has been designed in composite material which is of the type

  turnstile and adjustable shutter stop.

  To obtain optimum and smooth maintenance of the flaps in the folded position on the front, the shutter stop has, on the one hand at the turnstile articulated on an anchor rod to the wall, a means of pressurizing said turnstile against the flaps on the front and, on the other hand, at the level of the adjustable stop, a firm clamping means in the spacing position chosen along the anchoring rod associated with a member

damper for shutter support.

  These characteristics and others will emerge from the rest of the

description.

  In Figure l l is a view similar to Figure lO showing the pivoting of the turnstile causing its approximation in

  direction of the end of the rod.

  In order to make the object of the invention more concrete, it is now described in nonlimiting embodiments illustrated in

figures of the drawings.

  The shutter stop illustrated is essentially made of composite material and includes the following elements: A metal lag screw (l) which has one end (la) conformoe to be connected by sealing in the wall or by screwing in a dowel ) drowned in the wall; at its other end the lag screw has a profiled and angled tab (lb) intended to receive by overmolding a rod (2) extending approximately to the shaped end (l) and the j

4 2827625

  rear part (2a) of ovoid shape is arranged above the lag screw to receive at articulation a turnstile (3) or "sage leaf" As a variant, it is not excluded that the lag screw (1) and the rod (2) are

in one piece.

  According to a characteristic of the invention, the turnstile (3) is articulated on the rear part (2a) of the rod so as to be adjustable in translation in order to ensure a support position on the turnstile against flaps (V) folded down in fa, cade and two recessed positions after angular pivoting,

  on either side of the support position.

  0 For this, on a rear shoulder (2b) of the part (2a) of the rod, a chanDrage (2c) is made, the bottom of which has a ramp (2d) with two notches (2e) formed angularly at 60 on either side 'other of the vertical axis of symmetry (x-x') of the part (2a). The recess (2c) communicates with the front face (2f) of the part (2a) by a central orifice (2g) and two successive stepped bores (2h, 2i). In parallel, the turnstile (3) has a hub (3a) intended to cover the shoulder (2b) of the part (2a) with a recess (3b) at the front receiving an elastic washer (4) as well as a clip. (5) having a split surface (5a) for cooperating elastically with a centering (2j) of the part (2a); All of these elements being held in position by a plug (6), the rod (6a) of which cooperates with the split rod (5a), while the head (6b)

  enters a housing (3c) of the hub.

  The hub (3a) of the turnstile (3) also has between the recess (3b) and the housing (3c) of the hub a wall (3d) on which is formed a profiled finger (3e) intended to cooperate with the ramp (2d) of the part (2a) as well as with the notches (2e) which constitute stopping points at the end of

  turnstile stroke, thanks to the elastic washer (4).

2827625

  Thus produced, it is understood that when the turnstile is pivoted in a substantially vertical position corresponding to the maintenance of a folded shutter on the front, the finger (3e) traversing the ramp (2d) forces said turnstile to move away from the part (2a ) of the rod and coming into elastic abutment against the flap, while in the extreme positions corresponding to

  notches and when the flap is released, the turnstile moves away from said flap.

  According to a preferred embodiment illustrated in Figures 10 and 11, the turnstile (3) is pivotally mounted in the central orifice (2g) of the rear part (2a) of the rod (2) along an axis (x-x ') angularly offset from the axis (y-y ') of said rod. The angular offset ((x) is about 2 dogrates. As a result, as shown in particular in FIG. 11, the pivoting of the turnstile (3) generates, at its profiled end (3f), a bringing together effect in relation to the flap folded down on the front In substantially horizontal position of the turnstile corresponding to the blocking position of the flaps, the end part (3f) is offset by a distance (e) of approximately 4 mm from the retracted position said

  turnstile, when the shutters are not folded down on the front.

  According to another important characteristic, the adjustable stop at the rear of the perrnet flap by its design on the one hand, easy adjustment and a locking block along the rod (2) and, on the other hand, an anti elastic support -shock and

flap anti-beat.

  For this, the stop is constituted by a profiled piece (7) in the shape of an ellipse, one end of which has a bore (7a) for sliding mounting on the rod (2) of the lag screw and extending by a recess ( 7b) surrounded by a threaded and split surface (7c); between the rod (2) and the

6 2827625

  recess (7b) is inserted a conical split bushing (8) and a clamping ring (9) is screwed onto the threaded and split seat (7c) to ensure, after adjustment, the blocking in position of the stop. As a variant, it is not excluded that the threaded and split seat (7c) is directly in relation to the rod (2) by eliminating the bush (8); the tightening being sufficiently extended

on the stem.

  The shutter stop, according to the characteristics of the invention, is intended to equip all types of windows and French windows, with the possibility of being 0 fixed to the right and to the left of the latter. Under these conditions, it is important that the stop (7) can occupy different angular positions depending on the application of the shutter stop. Thus, as shown in particular in Figure 9, the stop (7) is mounted with the ability to pivot and angular indexing relative to the rod (2) according to several preset positions. For this purpose, the bore of the stop (7) is mounted to slide freely on the rod (2) and has four grooves regularly distributed over a circumference, being offset by 90 to co-operate with four complementary ribs (2k) formed in overflow from the periphery of the rod (2). Advantageously, the four ribs (2k) are formed over a limited length of the rod (2), so that in the event of poor angular positioning of the stop (7), after fixing for example the rod (2) and pulls -bottom (1), it is possible to temporarily retract, by sliding, said stop (7) along the rod (2), so as to orient it correctly, in order to reposition it relative to the

ribs (2k).

  Illustrated in FIG. 9, by mixed lines, the different possibilities

  angular indexing of the stop (7) relative to the rod (2).

7 2827625

  At the opposite end, the stop (7) has a bearing surface (7d) internally receiving a stepped pin (10) mounted elastically against a spring (11) also bearing on a plug (12). Thus, it is understood that when the flap is folded in front against the pin (10), it moves back

  against the spring (11) by playing the role of a damper.

  The flap folded and held between the elastic support of the pin (10) and the turnstile (3) is thus perfectly locked without play and without risk of impact

  during maneuvers and therefore without the possibility of beating under the effect of the wind.

  According to an embodiment illustrated in Figures 7, 8 and 9 in particular, the damping member of the flaps folded down on the front, is constituted by a tongue (7e) mounted with capacity for elastic deformation in the thickness of the stop (7). For example, this tongue (7e) is formed directly during the production of the stop (7) and results from a suitably profiled cut. The free end of the tongue (7e) has a

pawn (14).

  It is thus seen that by the adjustment in position of the stop on the rod thanks to the split bushing - clamping ring system, one can easily obtain the

  adequate adjustment with angular alignment of the turnstile and the stop.

  The shutter stop also comprises, as illustrated, a washer (13) adjustable along the rod to be pressed against the wall, hiding the fragments of the bore. This washer can be either slidably mounted

  just have a shoulder and a locking screw.

  The advantages clearly emerge from the description, it is further emphasized:
