The system in accordance with the invention enables the shutter to be released and closed in an easy operation which does not require the user to lean out of the opening.

Description

MANEUVERABLE SYSTEM FOR STOPPING A SHUTTER FLAP
AND SWING HOOKING SET
The invention relates to a maneuverable shutter stop system; it applies to shutters of the casement type pivoting around hinges (or other equivalent articulations), with a view to locking them in the open position and allowing them to be released for closing. The term "shutter wing" generally means any pivoting closure element intended to equip an opening (doors, windows, French windows, etc.). The invention extends to a so-called hooking assembly, constituting the system.

 Traditional shutter stops, such as a turnstile stop (patent FR 2,539,797 ...) are of very simple structure and generally hold the shutter satisfactorily against the portion of the wall near the opening; however, these systems are difficult to access when it comes to releasing the leaves and the user must bend over the opening to reach them, which is most of the time an awkward and sometimes dangerous execution operation.

 Many systems have been designed to try to eliminate this fault. Some of these systems act by immobilizing the flap by its part close to the hinges (patents FR 2 406 713, 2 547 852, 2 495 696, 2 214 312 ...) other systems directly block the hinges (FR patents 2 443 554, 2 366 429 ...). However, even oversized, these systems give an insecure fixing of the leaves: in case of strong wind, they are subjected to very high forces due to the lever arm that constitutes the shutter and can be damaged with risk of deterioration of the shutter itself. Other stop systems have been designed by craftsmen or on paper but are not used (or are used in a very limited way) due to their complex structure (one of the criteria for wide distribution of this accessory being its low price and its ease of installation). For example, the patents FR 1 492 203, 2 504 969, 2 526 074, 2 458 659 ... describe mechanical systems for operating shutters from inside the house; these systems are much higher cost than traditional systems and their implementation is much more complex and expensive.

 The present invention proposes to provide a new system for stopping a shutter wing. It aims at a maneuverable system making it possible to release the shutter by an easy operation which does not oblige the user to bend over the opening.

 Another objective is to provide a simple structure system the cost of which is compatible with a wide distribution of this accessory.

 Another objective is to provide a system whose installation requires only simple and inexpensive implementation operations.

 Another objective is to immobilize the shutter perfectly in the open position, without play and without risk of damage or accidental folding in the wind.

 To this end, the maneuverable stop system according to the invention comprises, on one side, a hooking assembly fixed to the wall at the free edge of the leaf (for the open position thereof) , on the other hand, an operating assembly fixed on the leaf so as to be able to cooperate with one hooking assembly in the open position of said leaf.

The hooking assembly essentially comprises
means of fixing to the wall,
a hook of suitable shape for
ability to hang the leaf at its free edge in order to block it,
and elastic means arranged to urge said hook towards a hooking position and to authorize its retraction towards a withdrawal position.

The operating assembly essentially comprises
a gripper positioned on
the flap on the hinge side,
an operating rod linked to the gripping member in order to be able to be actuated by the latter, this rod extending between said gripping member (hinge side) and the free edge of the flap at the hook,
and a rod end adapted to push the hook from its hooking position towards its withdrawal position when the operating rod is actuated.

 According to another characteristic of the invention, the hook has an oblique retraction ramp, arranged to generate the retraction of said hook towards its withdrawal position under the thrust of the leaf at the end of opening.

 In addition, according to a preferred embodiment, the hooking assembly comprises a support stop arranged in opposition relative to the hook, in order to ensure a pinching of the leaf between said stop and the hook in the open position. of said leaf. Preferably, this stop is associated with means for adjusting its position, so as to allow the leaf to be pinched without play, whatever its thickness.

 Furthermore, the gripping member of the operating assembly may very simply be constituted by a handle arranged to allow, firstly, to actuate the operating rod in order to release the leaf, then to pull it ci in the closing direction.

 As will be better understood below, such a system can take a very simple embodiment, giving it a low cost compatible with a wide diffusion of the system. The hooking assembly can be manufactured at a cost equivalent to that of a turnstile stop and its installation on the wall is as simple as that of these stops. The operating assembly is preferably composed of a simple sliding rod, moved along its longitudinal direction by the gripping member; its installation on the shutter is as simple and rapid as the installation of a simple handling handle with which the shutters are often fitted in order to facilitate their closing.

 Each leaf is opened in the traditional way by pushing it outwards towards the wall. In the vicinity of the wall, the free edge of the leaf makes contact with the oblique ramp of the hook and, by the play of elastic means, pushes the latter towards its withdrawn position. At the end of movement, the hook returned to its hooking position locks the leaf which is pinched by its free edge between the support stop and said hook. I1 it should be noted that such a locking of the leaf which takes place on a part of the latter situated opposite the hinges ensures excellent retention of the shutter like the turnstile stops. user grabs the handle which is within easy reach on the side of the hinges, and maneuvers it to actuate the rod in order to push the hook towards its withdrawn position.

The leaf is then released and an appropriate pull on the handle makes it possible to close it.

 The invention extends, as such, to a hooking assembly of a shutter leaf, which benefits from a very simple structure and a very low cost price, this assembly being very particularly suitable for equipping the system previously described. This hooking assembly essentially comprises a fixing support against a wall, a hook having a hooking beak situated in opposition with respect to said support and elastic means urging said hook; this assembly is characterized in that the fixing support and the hook consist of two separate elements, connected by at least one bent spring forming the elastic means, one end of each spring being inserted and secured in a housing formed in the element forming the fixing support, while the other end of each spring is inserted and secured in a housing formed in the element forming the hook. Preferably, the springs are two in number and formed by spring rods.

 In addition, according to another characteristic of this assembly, the element forming the fixing support carries a support stop, arranged to constitute a projection of adjustable thickness with respect to the front face of said element. This stop is advantageously constituted by a cylindrical pin provided with a thread on its peripheral surface, the element forming the fixing support having a conjugated tapped hole, with an axis perpendicular to its front face.

 As will be better understood later, such a hooking assembly in which the fixing support and the hook can be constituted by molded parts, can be produced in large series at a reduced cost.

The invention having been explained in its general form, other characteristics, aims and advantages will emerge from the description which follows with reference to the appended drawings, which, by way of non-limiting example, present a preferred embodiment. ; on these drawings which form an integral part of the present description

- Finally, Figures 12a, 12b, 12c, 12d and 12e are diagrams of operation of the system.

 The maneuverable stop system shown as an example in the figures, equips a shutter flap 1, pivoting around hinges 2 to close or release a window opening 3 which we see in 4 the peripheral wall. This system is intended to lock the leaf 1 in the open position near the wall 4, without play and without risk of failure in strong winds, and to enable the leaf to be released by a simple and easy operation, carried out from the window, without having to lean through it, whatever the width of the window.

 This system comprises two separate assemblies, which are called upon to cooperate in the leaf opening position: a hooking assembly 5 and an operating assembly 6.

 The whole hooking 5 is sealed in the wall in correspondence with the free edge 1a of the leaf when the latter is in the open position.

 The operating assembly 6 is fixed to the leaf 1 and extends transversely between the free edge 1a thereof and the opposite edge 1b provided with the hinges 2.

 The operating assembly vr e 6 which is shown in detail in FIGS. 2, 3, 4 and 5, essentially comprises a handle 7 which actuates an operating rod 8 slidably mounted transversely relative to the flap and provided with a nozzle 9 located near the free border.

 The handle 7 has a flat shape obtained by cutting and is articulated by a pin 10 on a support 11 fixed by screwing on the flap of the shutter. In the example, this support comprises a fixing foot 11a which is fixed by screws to the leaf and forms a slide serving as a sliding guide for the rod 8.

 In another embodiment, the guide of this rod 8 can be provided by a wooden cross member of the leaf, a cross member provided for this purpose with a guide groove. The support 11 can then be constituted by two simple facing brackets, fixed on this crosspiece.

The handle 7 is extended opposite its articulation 10 by a finger 12 which 'has the function of ensuring the displacement in translation of the rod 8 during the pivoting of the handle. Said handle is positioned by
relative to the leaf so that its free end 7a is
oriented towards the free edge 1a of said leaf, the finger 12 being located opposite to said free edge, on the side of the
border lb and close to the latter. The handle 7 is
thus easily accessible from inside the house at
through the opening 3.

Finger 12 is provided at its end with
two nipples 13, formed by an axis force-fitted into a
piercing the finger in order to pass on either side of
this one. These nipples are of axis parallel to the axis
hinge 10 of the handle and are housed in
buttonholes 14a formed in a pusher 14.

The pusher 1 4 is fixed by means of a
screw 15 at the end of the rod 8. The buttonholes 14a
extend along a direction perpendicular to the plane of the leaf so that the pusher 14 engaged with the finger 12
is driven in a translational movement guided by the
rod 8 when the finger pivots about the axis 10; the
displacement D of the pusher and of the rod 8 is directed towards the
free edge of the leaf when pulling T in direction
opposite is exerted on the handle 7, as illustrated by
arrows shown in Figure 3.

The operating rod 8 which extends
transversely between the two edges la and lb of the leaf
consists of a flat iron and is guided in its
sliding, on the one hand, by the foot lla of the support already mentioned, on the other hand, by a guide bridge 16 (as already
indicated, a crossmember with a groove can replace these
guides).

The rod end 9 which is located at
the end of the rod 8 can be formed by a simple fold
flat iron. This tip is positioned, thanks to a length
appropriate stem, so as to project or
shrinkage from the free border la during
displacements of the rod; this end piece 9 is thus brought to cooperate with the hooking assembly or on the contrary to
stay away from it.

The above operating set 6
described can be made of steel by cutting and folding with the exception of the pusher 14 which is advantageously constituted by a molded piece of synthetic material; the cost price of this set is thus greatly reduced; it is installed by traditional screwing operations, either in the workshop during the manufacture of the shutter, or, if necessary, on site.

 Furthermore, the hooking assembly 5 which is shown in detail in FIGS. 6, 7, 8, 9, 10 and 11 essentially comprises two separate elements, namely a fixing support 17 and a hook 19 which are connected by two rods - springs 18.

 The support essentially consists of a plate 17 molded in synthetic material, which is hollowed out on its rear face to form a housing capable of containing two of the ends 18a of the spring rods 18; each end 18a is locked in the plate thanks to a notch 17a by which it penetrates therein and, at the end, thanks to a blind hole 17b into which a short curved section 18b of the spring end is inserted. Of course, these blocking means can take different embodiments.

 The plate 17 is closed by a rear plate 20, in the metallic example, which traps the ends of the spring rods. It is fixed against the wall by any suitable fixing member, in particular by screws 21 cooperating with dowels anchored in the wall.

 In addition, the plate 17 has in its central part a short cylindrical portion 22 delimiting a tapped hole, with an axis perpendicular to its front face (which is substantially parallel to the wall). A cylindrical pin 23 provided with a thread on its peripheral surface is screwed into the tapped hole 22 so as to constitute a support stop forming a projection of adjustable thickness relative to the front face of the platina. In the example, the pin 23 is hollow and molded in synthetic material.

 The two metal spring rods 18 which connect the fixing plate 17 and the hook 19 have ends opposite to 900 (18a, 18c) and form at the elbow an elastic loop 18d.

 The hook is constituted by a hook-piece 19 molded in synthetic material. This part is composed of a sole 24 hollowed out on its rear face to form a housing for the ends 18c of the springs, and a hooking spout 25.

 The sole 24 is provided with means for blocking the ends 18c of the springs, constituted in the example, on the one hand, by a bayonet entry 24a by which these ends penetrate into the sole, on the other hand, by a boss 24b blocking in which are inserted short curved sections 18th of said ends. The mounting of the ends of springs in the sole 24 is effected by notches 24c that said sole has on its sides.

 In addition, the hooking spout 25 of the hook piece which projects from the front face of the sole has a generally triangular section to form a shoulder 25a oriented towards the fixing plate 17 and an oblique access ramp 25b on the opposite side this ramp 25b is extended, on the side of the shoulder, by a short bearing face 25c arranged to come opposite the end piece 9 of the operating assembly in the leaf opening position; on the other side, the hook-piece is provided with an extension 26 to allow, if necessary, to be actuated manually.

 It is conceivable the structural simplicity of such a hooking assembly, the parts of which can be mass produced at very low cost and the assembly of which comes down to the insertion of the ends of the spring rods. Installation of this assembly on site is as simple as that of a turnstile stop.

 Figures 12a to 12e illustrate the operation of the system.

 The shutter i is opened in the traditional way by pushing it in the direction of the arrow F drawn in FIG. 12a.

 At the end of opening, the free closure of the leaf contacts the oblique ramp 25b and pushes back the hook 19 by the play of the elasticity of the spring rods 18 (FIG. 12b).

 The projection formed by the stop 23 having been adjusted according to the thickness of the leaf, the latter snaps into the hook when it arrives against said stop (FIG. 12c). The leaf is then pinched-between this stop 23 and the hooking spout 25, by its free edge opposite the hinges. In this position, it offers little leeway and the forces transmitted to the stop system are without the multiplier lever arm and remain low.

No risk of exhaustion or damage is to be feared even in very strong wind.

 To close the leaf, the user grasps the handle 7 and exerts a traction T on it (FIG. 12d). This maneuver is easy and natural due to the proximity of the handle and its orientation; it causes the rod 8 to slide in the direction of arrow D: the rod end 9 bears against the bearing face 25c of the hook and pushes the latter back until it comes into a position of withdrawal from the leaf.

 The leaf is then released and the continued pulling on the handle 7 causes it to pivot in the closing direction (Figure 12e).
