Definitions

  • the present invention belongs to the field of building supplies, in particular hardware for windows, patio doors and the like, and more particularly relates to a safety device for a window handle.
  • Shutters can certainly be very effective, when they are made of extruded metal for example, but their use is problematic during the day because their closure prevents light from entering through the window. window, and their cost remains quite prohibitive especially when it comes to fitting all the potentially passable windows of a house.
  • HOPPE AG markets secure handles under an eponymous registered trademark, HOPPE®, which is the subject of several patents and patent applications, the most relevant of which are listed below.
  • Some handles offer more security against unwanted openings from the outside by the addition of organs and locking and / or blocking mechanisms in the rosette, and sometimes thanks to a connected box which sends alerts in the event of an accident. 'actuation of the handle. These solutions remain very ineffective against burglary and completely unsuitable for the safety of children because they can be easily operated like simple handles.
  • a ratchet system prevents the burglar from operating the window opening from the outside, and the handle anchor is reinforced to resist tearing.
  • FR2606445A1 describes a device inserted between the handle of a window and the frame thereof, allowing manual or spontaneous locking of the handle, in order to limit attempted break-ins and accidents by children.
  • This device consists of a box comprising a slide in which is housed a lock plate, the box comprising a barrel provided with a cam, and an articulated lever on which is fixed a tension spring whose other point of fixation is located on said box.
  • the lever extends onto the latch plate to fit between the two tabs of the latch plate.
  • the present invention aims to overcome the drawbacks of the prior art described above, in particular to strengthen the security of windows and the like against unwanted intrusions, to delay and limit break-ins, and to protect unwary children from the risks of accidental defenestrations and access to dangerous places.
  • the present invention relates to a security device for a window, door or the like intended to be mounted between a handle and an opening and crossed by a square of the handle, comprising a body and a locking mechanism for locking. and unlock the rotation of the square.
  • This device is remarkable in that it comprises two push buttons on two opposite sides of the body, each of said buttons actuating a locking member, and in that the locking mechanism has a locked position, corresponding to a release of the buttons, in in which the blocking members are able to block the square in rotation so as to prevent the opening of the leaf, and an unlocked position, corresponding to simultaneous pressing of the two buttons, in which the blocking members are spaced apart. one of the other freeing the rotation of the square.
  • each locking member comprises a rod extending along a longitudinal axis of the body and a U-shaped branch extending perpendicularly to said rod, the branches being arranged opposite so that in position locked, internal surfaces of said branches delimit a blocking volume blocking the rotation of the square which passes through it.
  • each locking member is slidably mounted in the body along a longitudinal axis of said body, being fixed to a push button, and the push buttons are each constrained by a spring.
  • each spring is a compression spring arranged between the body and a collar of the rod of the locking member fixed to the button constrained by said spring, and the simultaneous pressing on the two buttons produces a separation of the branches, the 'one relative to the other, freeing in rotation the square which passes through the safety device.
  • the body has a front face and a rear face, crossed by a central opening capable of receiving the square.
  • the two buttons are placed on an upper face and a lower face of the body.
  • the body comprises fixing means to be mounted, interposed, between the handle, or a rosette thereof, and the opening of the window.
  • the safety device further comprises an extension and coupling member capable of receiving the square at one end, and of being coupled in rotation in a housing of the opening at the other end.
  • Another subject of the invention is a window or door handle, equipped with a safety device as shown, and a window comprising such a handle.
  • a security device intended primarily for window handles and the like. This non-limiting example is given for a better understanding of the invention and does not exclude the use of the device on door handles, for by example securing access for children to certain risky places such as balconies, terraces, etc.
  • handle designates both a single handle and a handle combined with a rosette
  • window indirectly designates a window opening.
  • the figure 1 shows a safety device 100 comprising mainly a body 10, two push buttons 20 for unlocking, on one side and the other of the body 10, and a locking mechanism 30 actuated by said buttons, the simultaneous pressure of the two buttons allowing to unlock said mechanism.
  • the safety device 100 can be mounted on a window 200 with a handle 210 by being inserted between said handle and the window sash. Indeed, the safety device 100 can be crossed by the square of the handle 210 and thus makes it possible to block or authorize the rotation of said square and, thereby, the actuation of said handle to open the window. In the example of figure 2 , the safety device 100 is placed between the frame of the window sash 200 and a rosette 220 cooperating with the handle 210.
  • buttons 20 it is necessary to simultaneously press the two opposite buttons 20 to unlock the locking mechanism of the safety device 100 and thus release the rotating handle 210 to open the window 200.
  • the operation of the locking mechanism will be detailed below but we can already note the difficulty of unlocking such a mechanism from the outside, by a burglar, and from the inside by a child below a certain age. Indeed, in both cases it is necessary to use both hands to open the window: one hand simultaneously presses the two buttons while the other hand turns the handle. Therefore, the burglar will have to make a larger hole in the window to access the security device with some freedom of movement, which will deter the burglar or at the very least delay the break-in. In addition, children under a certain age do not have their hands large enough to press both buttons simultaneously. with one hand and attempt to turn the window handle with the other hand, nor the force necessary to press said buttons with one hand.
  • the body 10 has a parallelepipedal shape defining a front face 11a, able to receive the handle of the window, a rear face 11b, intended to bear against the frame of said window, one face of top 12a and a bottom face 12b, each receiving a push button 20, and side faces 13.
  • the body 10 is crossed between its front 11a and rear 11b faces by a central opening 111, which will receive the square of the handle, and by fixing holes 112 by means of which the safety device 100 can be fixed between the rosette of the handle and window frame.
  • the central opening 111 is located substantially in the center of the body 10, has a circular shape adapted to the passage and to the rotation of the square, which also passes through the locking mechanism 30 as explained below.
  • the shape of the central opening can be any, oval, square or other provided to allow cooperation with the dimensions of the locking mechanism 30 for the passage of the square handle.
  • the fixing holes 112, according to the illustrated embodiment, are for their part placed on one side and the other of the central opening 111, at an equal distance therefrom, along a median longitudinal axis of the body 10. .
  • the fixing holes 112 are adapted to handles with rosette and have an edge in the plane of the front face 11a of the body 10 and an opposite edge projecting from the rear face 11b.
  • This configuration allows the security device to receive the rosette on its front face 11a, with the ends of the rosette inserted into the fixing holes 112 through said front face, and to fit into the window frame via the projecting parts.
  • holes 112 in the manner of a rosette.
  • the protruding parts of the fixing holes 112 extend the end caps of the rosette and replace them to establish the fixing on the window frame.
  • the safety device 100 is designed to be marketed alone and adapts to existing handles thanks to a simple assembly, but can also present variants incorporated and marketed with handles in a single set.
  • the body 10 can be made up of two half-shells, front 10a and rear 10b, which can be fitted together as shown in FIG. figure 7 , external faces of said half-shells constituting the front 11a and rear 11b faces of the body 10.
  • the advantage of this design lies in the possibility of opening the safety device 100 if necessary, for a repair for example.
  • the two half-shells 10a and 10b are fixed to one another via fixing holes 14a and 14b facing each other which for example receive screws.
  • the assembly of the two half-shells is carried out by snap-fastening or by any rapid and reversible fixing system.
  • the upper and lower faces of the half-shells 10a and 10b are shaped to receive the push buttons 20, thanks to peripheral edges bypassing said buttons leaving a functional play.
  • Each push button 20 has a cylindrical shape with a circular base surmounted by an end 21 shaped to better cooperate with the finger which will press said button.
  • the two buttons 20 are placed on the upper faces 12a and lower 12b of the body 10 and will be designated, when necessary, by upper button and lower button.
  • the axes of the buttons 20 are substantially parallel to the median longitudinal axis of the body 10, being offset at an equal distance from one side and the other thereof. This particular arrangement of the push buttons 20 matches the operation of the locking mechanism 30.
  • the locking mechanism 30 is composed of two locking members, each member being integral with a push button 20 and comprising a longitudinal rod 32 which extends along the axis of said button and a transverse branch 33 which s' extends in a direction perpendicular to that of the rod 32.
  • the locking members are slidably mounted in the body 10.
  • each rod 32 is fitted to a base 22 of the push button 20 and ends with a collar 321 at its free end.
  • Each rod 32 is mounted as a slide with respect to the body 10 between a main guide element 15 and additional guide elements 16, said guide elements being in this case manufactured in one piece with the front half-shell 10a according to the mode realization illustrated.
  • Each locking member is mounted, via the free end of its rod 32, on a spring 35 placed between the collar 321 of said rod and the body 10, and more precisely between the collar and a cylindrical housing formed in the upper edge or lower half-shells 10a and 10b.
  • the movement of the blocking members is conditioned by both the pressure on the buttons 20 and the constraint of the springs 35, so that each button 20 is monostable “normally open”.
  • the actuation of the buttons 20, and therefore of the locking mechanism requires continuous pressure, the cessation of which produces a return of said buttons to their stable position under the effect of the return of the springs 35.
  • the transverse branches 33 each have a U-shape and are arranged facing one another so as to delimit, when they are in contact, a volume 31 which substantially corresponds to the volume of the square of the handle as shown in the figures 3, 4 and 7 .
  • the branches 33 have dimensions adapted to block and release in rotation the square inserted in the volume 31 according to their mutual spacing as explained in more detail below.
  • the safety device 100 has a locked state, shown in figure 8a , with the buttons 20 released and the square 230 locked in rotation between the branches 33, and an unlocked state, shown in figure 8b with the buttons 20 pressed simultaneously and the branches 33 apart, freeing the square 230 in rotation.
  • the push buttons 20 are in their stable position and the springs 35 are in their equilibrium position, preferably pre-stressed to keep the buttons 20 in abutment against the body 10 by their bases 22, each base having a peripheral surface which comes in abutment against the body 10.
  • the rods 32 are in abutment by their flanges 321 against the guide elements 15 and 16.
  • the branches 33 fit around the square 230 of the handle and block it in rotation. around its axis, the internal faces of the U-shaped branches 33 defining a volume complementary to the square in which said square is blocked in rotation, or at the very least is arched at an angle less than the angle necessary for the opening of the window.
  • buttons 20 are simultaneously pressed P pushing the locking members in two opposite directions. Consequently, the branches 33 move away from one another and release the square 230 in rotation, the outline in broken lines in the figure representing the initial position of said square. It should be noted here that the square 230 can be released in rotation before the maximum separation of the branches 33. In practice, the central opening 111 of the body 10 must be released so that the square regains all its rotational mobility.
  • buttons 20 allow the springs 35 to return the locking members to their initial position with the branches 33 contiguous, corresponding to the locked state of the safety device 100.
  • the pressure force required to press the buttons 20 depends directly on the stiffness of the springs 35. Preferably, the pressure force should not be within the reach of children.
  • the safety device to simultaneously press the push buttons 20 with one hand, a user can for example use his index finger and his thumb to press the upper button and the lower button respectively.
  • the safety device must have a length, and more precisely a distance between the ends of the push buttons, suitable for an adult hand of average size.
  • the safety device 100 When it is installed between the handle and the frame of an existing window, the safety device 100 provides an additional thickness which can prevent the square, of limited length, from reaching its housing in said frame. This situation is illustrated on the figures 9a and 9b .
  • a square extension 50 which fits into the square 230 by a first end, hollow, and inserted into the housing 240 by a second end, solid, opposite to the first, the shape of the extension square resembling that of a socket head bolt.
  • the diameter of the square 230 must be substantially equal to the internal diameter of the hollow end and the diameter of the solid end of the extension 50.
  • the dimensions of the blocking volume 31, in other words the dimensions of the branches 33 of the locking mechanism are adapted to the external diameter of the hollow end of the extension 50, the difference between the external and internal diameters of said end being such that the locking in rotation takes place both on the extension and on the square alone, when the latter has sufficient length and the use of the extension is no longer necessary.
