Description

The present invention relates to the field of control devices for locking/unlocking systems of an opening such as a window or door leaf. It relates in particular to the devices which can be sold separately from the openings to be installed on site on locking/unlocking fittings of the espagnolette type. More particularly, the invention relates to control devices which are surface-mounted on an opening jamb, in particular for sliding door or window openings.

It is common to use locking/unlocking devices with espagnolette with pivoting handles, in the field of openings, such as windows or doors, the opening of the opening of which is generally done by rotation around an axis. of pivoting, said to strike.

Indeed it is conventionally known in the field of impact openings, to use control devices making it possible to act on the locking/unlocking of locking/unlocking fittings of the espagnolette type embedded in the amount of an opening, including a rotating handle. This handle acts by means of an actuating shaft, generally a rod with a square section called the actuating square, which is inserted into engagement in a through hole with a square section, the cremone bolt follower, so as to transform the rotational movement of the handle into a translational movement on itself of the locking/unlocking member following an amount of the leaf. This locking/unlocking member is generally in the form of at least one rod, usually two rods. The control handle is generally wall-mounted on a sash post, so that its rotation takes place around the actuating shaft mounted transversely to the plane of the sash.

Conventionally, in the open leaf position, the handle is horizontal (at 90 degrees) relative to the upright on which the handle is mounted. A maneuver with an angular stroke of 90 degrees of the handle thus makes it possible to operate the handle follower of the cremone bolt by a quarter turn, to unlock the window leaf by turning in one direction and to lock it by turning the handle In the opposite way.

These devices have competitive costs directly related to their mass production.

However for these devices with espagnolette, in the unlocked position, the handle which is at 90 degrees with respect to the amount on which it is applied, can interfere visually or physically.

In addition, particularly in the case of sliding leaves, there is a problem of ergonomic use of the handle. Indeed on a sliding leaf, the user will open the leaf by making it translate. He will therefore have to pull the handle not towards him as for a keyhole window, but in the direction of translation of the leaf. In open leaf position, the handle being horizontal (at 90 degrees) in relation to the upright on which the handle is mounted, the grip of the handle can be slippery and therefore not very ergonomic.

Another problem is the risk of crutch degradation. In fact, a horizontal handle for maneuvering the secondary leaf of a sliding door in a horizontal plane can lead to a risk of the end of the handle striking the chicane upright of the main leaf.

Another drawback is that the horizontal handle limits the opening of the leaf to a space at least equal to the length of the handle.

It is thus already known to find, on sliding sashes, handles adapted to this particular type of joinery, but these handles are generally installed vertically, with a maneuvering member of the actuating square or with a very short lever arm , or with a crutch whose angular stroke is less than 90 degrees, generally not exceeding 20 degrees.

In the patent application FR2865493 , a device has thus been proposed making it possible to cause the rotation of an actuating shaft of a cremone bolt or the like over an angle of given value by means of the rotation of a handle or the like over an angle of much lower value at said given value. This device finds applications in particular in the control of cremone bolts for doors and/or windows, in particular of the sliding type for residential buildings or the like.

However, these handles have a cost which remains higher than a simple knock handle, due to a mode of operation and therefore a more complex design.

The patent application FR3004207 describes a cremone bolt control device capable of controlling combined quarter-turn and half-turn locking systems. The device comprises a drive shaft, one end of which fits into an operating member and the other end couples to a coupling end of an adapter shaft. The coupling end of said driver shaft has two projecting lugs oriented axially and whose lateral surfaces can come to rest on projecting surfaces of a cavity at the end of the coupling part of the adapter so that said shaft drives said adapter shaft in rotation over a first angular sector of travel of said shaft and that said shaft does not drive said adapter shaft in rotation over a second angular sector of travel of said shaft, different from said first angular sector.

The patent application FR2836505 describes a lock with several locking points of the type comprising a follower operable by a crutch. The lock comprises an actuator comprising a toothed sector coaxial with the follower, capable of being driven in rotation by the follower in a direction of rotation and remaining in position when the follower is returned to position by an elastic means, said actuating member part of a kinematic chain for actuating locking rods. For this purpose the follower may include a lug cooperating with the edges of a slot of the actuator so that when the stand is actuated downwards, the follower does not act on the actuator because the lug freely debates inside the light of the actuator without acting on it, whereas when the handle is operated upwards, the lug of the follower pushes the actuator in the direction of rotation corresponding to actuation of the handle.

The invention aims to solve at least in part the problems mentioned above. It aims to propose an alternative control device for a locking/unlocking system of an opening using a cremone bolt, and more particularly applying to a sliding opening. It aims in particular to provide a device having significant mechanical robustness over time, the device being subjected to significant and frequently repeated mechanical stresses.

It will be understood that, without departing from the context of the invention, that the sash can be oriented differently with respect to the frame, for example so that the sash slides in a vertical direction and that the rod then slides along of the closing post in the longitudinal direction.

Identical references or references increased by the acronym prime may be used from one figure to another to designate identical or similar elements.

According to a first exemplary embodiment, the control device comprises an actuating shaft comprising two separate shaft parts, a first shaft part 11, called the outgoing shaft part, according to the example with a square-shaped section, which will be on the side of the cremone bolt to cooperate directly with the cremone bolt to operate it. This part of the outgoing shaft is also qualified in the rest of the description as a cremone shaft, or according to the example of its shape as a cremone bolt square or an outgoing square. Said cremone bolt shaft 11 comprises two opposite axial ends 111, 112, one end of which 112 is capable of being inserted into the receiver orifice of the cremone bolt, orifice for actuating the locking/unlocking mechanism, orifice which constitutes the cremone bolt, said cremone bolt orifice having an internal shape adapted to that of the actuating shaft, with a square section according to the example.

Said device further comprises a second shaft part 12, called incoming shaft part, according to the example with a square-shaped section. This part of the incoming shaft is also referred to in the following description as a crutch shaft, or according to the example of the shape of the crutch as square or even an incoming square. Said incoming shaft part 12 comprises two opposite axial ends 121, 122, one end 122 of which is inserted on the side of the crutch 2 into an orifice 21 of the crutch, an orifice of internal shape adapted to that of the said crutch shaft, square section according to the example.

Said device comprises an angular travel converter 1 formed of a support 10 receiving said handle 12 and cremone 11 shafts, allowing an inactive angular travel, also called a dead angular travel, according to the example of 90 degrees, of the crutch shaft (incoming square) 12 with respect to the cremone shaft (outgoing square) 11, as explained later in detail.

Said converter also comprises a coupling means 13 between said support 10 and said actuating shaft, and more precisely according to the example said part of the outgoing shaft 11 (outgoing square) 11. Said cremone shaft 11 comprises at its end 111 , opposite its end 112 entering the lever, a hole 110 opening out transverse to the longitudinal axis of said shaft 11, said hole forming a duct 110 receiving coupling means 13 which comprises two projecting elements. Said coupling means is constituted according to the example of a round rod of small diameter, such as a pin, the ends of which form said projecting elements. Said coupling rod 13 is made of steel.

With reference to figures 1 to 7 , in particular to the picture 3 exploded, said support 10 has the shape of a hollow cylinder. Said support thus comprises a cylindrical wall comprising an internal recess constituting a cavity of circular section having an inlet 102 and an outlet orifice 101. Said incoming orifice 102 receives one end 121 of the crutch shaft 12 ( incoming square) and said outgoing orifice 101 receiving one end 111 of the cremone bolt shaft 11 (outgoing square). Said cylindrical wall also comprises two openings 103, 104 in the form of slots, crossing in the radial direction of said wall, which open into said cavity, or in other words these openings form two slots 103, 104 ( Fig. 7 ). These slots are oblong in shape, arcuate in the (circular) direction of the circumference of said cylindrical wall. They are arranged diametrically opposite on the circumference of said wall, that is to say they are hollowed out in opposition in the cylindrical wall of said support and following its circumference. These said lights 103, 104 have the same length. They respectively receive the ends 131, 132 of the coupling means 13, these ends forming the projecting elements, oriented radially on the cremone shaft and being housed respectively in said two slots 103, 104, entering from the cavity towards the exterior of the cylindrical wall. The length of said coupling means 13 is one length greater than the diameter of said cavity and adapted to the diameter of the cylindrical wall. With reference to the figure 7 in particular, each said slot 103, 104 respectively comprises ends 1031, 1032 and 1041, 1042 forming bearing stops for said projecting elements of said coupling means 13.

Starting from a locking position corresponding to a locked closing of an opening C, by maneuvering the crutch 2 following a rotation describing a first angular stroke of an amplitude a2, for example 90 degrees, the crutch shaft 12 ( crutch square) drives the support 10 in rotation by guiding in its slots 103, 104 around the projecting elements of said coupling means 13 (for example the pin), as illustrated in figure 4 and 5 , therefore in inactive angular travel, that is to say without producing drive of the cremone bolt shaft 11 in the cremone bolt, and this until the projecting elements of said coupling means 13 (the pin) come resting against one of the respective support stops 1032, 1042 of said slots 103, 104 as illustrated by the figure 6 and 7 . By continuing the angular stroke of the stand 2, the stand shaft 12 (incoming square) and the cremone shaft 11 (outgoing square) then enter into rotation by describing an active angular stroke of an angular amplitude α1, jointly driving the cremone bolt according to the same angular amplitude, said cremone bolt shaft 11 being integrally connected to the follower of the cremone bolt.

Once the dead travel has been carried out in said slots, the pin 13 in abutment against one of the respective ends of the said slots thus came to rest on the support 10 of the converter which was then able to transmit the torque force between the said stand shafts 12 and cremone bolt 11 over the remaining degrees of travel (α1) to the unlocking position. For example, the angular stroke of the cremone shaft 11 covers an angular amplitude α1 of 90 degrees, when the crutch as well as the crutch shaft describe a total angular stroke θ of 180 degrees (θ being the sum of α2 and α1 ). Thus, with a 180 degree maneuver of the handle 2, the cremone bolt follower operates a rotation α1 of only 90 degrees. The crutch 2 is found vertically following a closing upright M and directed towards up (+Z) when its starting position, for a locked closed position of the sash, is vertical along said upright M and directed downwards (-Z), as illustrated in figure 8 .

The length of the slots 103, 104 determines the amplitude of the dead angular travel that is desired, the initial position of said coupling means 13 (pin) for which the projecting elements bear against one of the respective stops of the slots 103 , 104, corresponding to the locked closed position of the leaf and to a given position of the handle, preferably vertically and downwards (-Z) along the closing post.

Said device is reversible, on returning to the locking position, when the crutch 2 is brought back to the locked position by turning it in the opposite direction to that on the way out operated during the unlocking maneuver, the crutch shaft 12 is also rotating in the opposite direction to the outward stroke and rotates the support 10 in dead angular stroke along its said slots 103, 104, until the coupling means 13 bears against the other end of said lights, the cremone bolt shaft 11 then being driven in rotation, and jointly the cremone bolt follower which operates a rotation until reaching the locking position (rotation of 90 degrees).

The angular travel converter comprises mounting aid means 3, 4 ( Fig. 9A ) for mounting the coupling means 13 to connect the direction of travel of the slot between its two ends to the direction of rotation of the operating member, so that the inactive angular stroke of the operating member can take place before the active angular travel of the actuating shaft, that is to say before the rotation of the actuating shaft can actuate the unlocking or locking of the locking/unlocking system with a lever. The direction of rotation of the operating member is suitable for opening the leaf to the left or to the right. According to the example of mounting a control device on the respective upright of the two sliding leaves V, V', installed in a chicane with respect to each other, as illustrated by the figure 8 , and the figure 9A , 9B and 9C , the mounting aid means are letters: the letter D (3) and the letter G (4), which are worn according to the example on the outer face of the wall of the support and at the ends of the slot (or the slots) of the support 10, for indicate where to position at the start of assembly the element (or elements) protruding from the coupling means, ie the pin 13, in the slot (or slots) of the support.

According to the example of the pictured bay figure 8 , steps for mounting the operating member 2′ for the sliding sash V′ located on the right of the operator looking towards the opening from the side receiving the operating handle, generally inside a building, are illustrated in figure 9A , 9B and 9C . In this case, the handle 2' is mounted on the right-hand upright M of the sash and the handle must be turned to the left to unlock the mechanism. The sash being in the closed position, the handle moves from a vertical position oriented downwards to the vertical position oriented upwards (in dotted lines) to unlock the mechanism, and therefore in the open position for the sash. As illustrated on the figure 9A and 9B , at the start of assembly of the maneuvering member, the maneuvering member 2' and the angular converter 1 are prepared: the handle 20' must be positioned at 90 degrees with respect to the sash post M which includes the espagnolette 5 , as well as the cover 220', which closed the sole 22', is pivoted through 90 degrees. When the outgoing shaft 11 is installed in the support 10, the pin 13 is introduced into the duct 110 of the said shaft 11 through the slots 103, 104 of the said support. One end 131, 132 of the pin 13 is positioned respectively in the slots 103, 104 of the support 10 in correspondence with the mounting aid means 3 represented by the letter D, as illustrated by the detail of the figure 9A zooming in on the angular converter. D is used for “Right”, the handle being installed on the right leaf according to this example. It can also be considered that naturally, a person who wants to open the sash, will preferably use his right hand to turn the handle, and thus the letter D corresponds to the hand used. Other conventions can be established to facilitate the correct assembly of the handle. One end 121 of the input shaft 12 having been inserted into the support 10, the other end 122 is inserted into the orifice of the handle sole 22'.

As illustrated in exploded view Figure 9B , the free end 112 of the output shaft 11 is introduced into the cremone bolt follower through a hole receiver, which includes the receiver amount M, in correspondence with said follower. The maneuvering member 2' is then fixed by screwing onto said receiving upright, using screws 201', 202' in the holes in the sole provided for this purpose as far as the corresponding holes in the receiving upright M. The cover 220' is then returned to the vertical to close said sole.

As illustrated by the figure 9C , it is then possible to put the handle 20' vertically, by bringing it back from its position at 90 degrees (in dotted lines) downwards, to close the opening V' against an upright P of the frame, by locking the locking mechanism in said amount of frame P. The crutch has therefore rotated 90 degrees downwards. The end of the pin which was positioned in the slot at the level of the letter D during assembly is found at the level of the letter G (4) at the other end of the slot which has turned 90 degrees when the handle is in locking position.

For mounting the device on the left opening V, not shown, the pin 13 will be positioned on the letter G at the start of assembly, when the stand 20 is at 90 degrees. When the stand is folded vertically downwards, the ends of the pin 13 are found at the level of the letter G.

.Said support and said crutch can be formed in one piece, in other words a single piece. For example, this one-piece part can be formed by molding a plastic material or another material, or by machining.

The examples have been described for a bay window comprising an opening sliding vertically in its own plane and locking against a fixed frame, but not limiting the invention. Indeed the opening could be locked against another amount such as another amount of the bay as an amount of another leaf or a fixed panel that would include the bay.

The invention has achieved its objectives by proposing a control device comprising an angular travel converter, compact, mounting instead of the usual actuating shaft of a handle of usual strike, this converter making it possible to transform an angular travel of a given amplitude of the maneuvering member, that is to say of the handle, into an operation for actuating the follower of the cremone bolt of an angular amplitude different from that of the operating member, in particular less than said given angular amplitude of the angular travel of the operating member. The converter makes it possible in particular to transform an angular travel of 180 degrees of the handle into a maneuver of a square cremone bolt of 90 degrees of amplitude. Furthermore, said device according to the invention has good mechanical strength, in particular high shear strength.

The invention also has the advantage of allowing the use of a conventional knock handle on sliding joinery without the risk of the handle colliding with the baffle upright and this without limiting the initial opening of the leaf carrying said handle. The invention therefore allows the use of a conventional knock handle mounted projecting on an amount of sliding joinery while retaining ergonomics suitable for maneuvering the leaves in translation. It is thus possible to equip an entire building with handles of the same style, whether for impact or sliding openings.

Manufacturers or installers of openings, in particular sliding ones, can in particular use a conventional handle but having a stay that remains vertical during the phases of movement of the sliding leaf and compatible with the use of a standard quarter-turn cremone bolt.
