    TECHNICAL FIELD OF THE INVENTION
    The present invention relates to the building industry, and more particularly the door crutches.
    STATE OF THE ART Generally, to actuate the bolt locks they equip, the door crutches are mounted on a bar, often metal, of square section to cooperate with the square hole in the nut of said locks. The crutches are squared in different ways. Sometimes at least one stand is fixed releasably by welding, crimping, etc. At least one of the two crutches must be dismountable in order to install and remove the lock. In this case, among the different types of crutch assembly, there are known among other things so-called "traditional" assemblies.
    It can be pin assembly, the shaft of the stand is then pierced transversely. The square is also pierced transversely near the end to receive the shaft of the stand. A pin passes through the two pieces to secure them. Most of the time, several holes are made on the square to adapt the assembly to different thicknesses of doors.
    We also know, among other things, so-called "fast" assemblies. For example, the self-locking assembly ratchet effect, as described in the patent application FR1356757 A, or the self-locking assembly by diagonal wedging, as described in the patent application EP1683933 A2.
    In the case of screw assembly, a threaded hole is made on the shaft of the stand, opening into the housing of the square. After mounting the stand on the square, a set screw is inserted into the threaded hole to tighten the square. To improve the tightening, the screw sometimes has a conical end. In this case, the resistance is further improved by producing a V-shaped groove on the square. The ultimate known improvement is to split the square longitudinally along the V-groove so that the tightening of the needle screw causes spacing of the two square sections thus formed. The square may even be composed of two "half-squares" of trapezoidal section, which will be opposed by the small base in order to reconstitute the "square" bar. All of these solutions have many disadvantages.
    For example, in the case of the pinned assembly, the spacing of the holes on the square creates a threshold effect, which rarely allows to limit the longitudinal play of the set of stands on the door. Indeed, during installation, the crutches are placed in contact with the door and one of the crutches is retracted until the hole of the stand can be matched with a hole in the square. If the drilling interval of the square is, for example, five millimeters, we can have at most one set of this value.
    In the case of screw assembly, we provide a solution to the game problem above. The disadvantage of this solution comes from the fact that by force of many manipulations, the pressure of the screw on the square decreases by wear and tear materials and sooner or later leads to the separation of the stand.
    In addition, these traditional assemblies have the disadvantage of being relatively long to implement, especially when a company must equip the many doors of a new collective housing for example.
    Finally, the patent application FR1356757 A solves some of the problems mentioned above but the precision and the number of parts used and making up the system make it a costly solution and unsuited to a professional installation.
    As for the patent application EP1683933 A2, it also solves some of the problems mentioned. Its main disadvantage, however, is the difficulty of dismantling the crutch. Indeed, it is necessary to use a rod that is introduced "blind" in a hole to tilt the blocking plate. If the doors have been fitted by the door manufacturer or by a laying company, it is unlikely that the small disassembly rod and the instructions for use will be available to the end user, who himself was able to to get rid of. In addition frequent movements or vibrations and wear can cause the handle to take the game, or even to disassemble.
    The present invention attempts to respond, at least in part, to at least one of the aforementioned problems.
    SUMMARY OF THE INVENTION
    The present invention relates to a door or window handle comprising at least one stand and a drive shaft for an opening and closing system, said stand comprising at least one gripping part and a shank, said shank comprising a socket receiving configured to receive a connection device of the stand to the drive shaft, the connecting device being configured to be secured to the stand and to allow free engagement of the stand on the drive shaft according to a first direction, and to ensure a blocking of this engagement in a second direction, the connecting device comprising at least one pierced part configured to be traversed by the drive shaft and to be biased in contact with the axis of drive, by the action of a return member and a stop member, so as to secure the crutch and the ax e said drive being characterized in that the abutment member is movable in at least a first and a second position, said first position prohibiting the disengagement of the stand from the drive shaft, and said second position allowing the stand to be disengaged on the drive shaft.
    The present invention thus allows a very fast assembly and disassembly of the handle. Indeed, for mounting, simply put the stand on the drive shaft and push it to the stop on the door or the plate. No tools are needed and the assembly time is reduced to a minimum.
    The present invention allows to have a very small game once the stand is installed. In addition, an increase in play, due for example to the necking of the wood of the door, is easily compensated by a simple pressure on the stand in the longitudinal direction of the drive shaft.
    The present invention allows for a self-locking system. Indeed, the biasing of the pierced part allows, through the wedging phenomenon, to secure the stand to the drive shaft. This also allows to avoid loosening phenomena due to wear of the handle.
    In addition, the present invention advantageously allows forced locking by the use of a threaded stop member. Indeed, if one wishes to increase the blocking force, it is sufficient to screw the abutment member to its contact with the drive shaft, thereby providing a support transverse to the axis.
    Finally, the present invention ensures easy and quick disassembly, simply by loosening the stop member. This operation is then intuitive since similar to that operated on a traditional crutch screwed.
    The present invention also relates to a mounting method of a handle according to the present invention on an amount, said mounting method comprising at least the following steps: - displacement of the stop member according to said first position; - Introduction of the drive shaft in the connection device secured to the shaft of the stand;
    This mounting method is thus reduced to a minimum allowing a significant gain in terms of installation time.
    Advantageously, the step of moving the abutment member is performed during the machining of the present invention so that at its output from the factory the abutment member is already positioned in said first position.
    The present invention also relates to a method of dismounting a handle according to the present invention on a post, said mounting method comprising at least the following steps: positioning of the abutment member in the second position so as to allow disengagement the stand on the drive shaft; - Removal of the drive shaft of the connecting device secured to the shaft of the stand.
    This disassembly process is simple and thus reduced to a minimum allowing a significant gain in terms of time of uninstallation or maintenance.
    Finally, the present invention relates to a leaf comprising at least one upright, an opening and closing system, and at least one handle according to the present invention.

    DETAILED DESCRIPTION OF THE INVENTION
    Before beginning a detailed review of the embodiments of the invention, are set forth below optional features that may optionally be used in combination or alternatively: in said first position prohibiting the disengagement of the stand 10 from the axis of 30, the stop member 23 is positioned to hold the pierced piece 25 at an angle and in contact with the drive shaft 30.
    This ensures a first level of locking of the stand 10 on the drive shaft 30, a self-locking.
    This allows the easy introduction of the drive shaft 30 into the connecting device 20 through preferably the entire cavity 22 and the pierced part 25, and the return member 24.
    In said second position for locking the stand 10 on the drive shaft 30, the abutment member 23 is positioned so as to allow the pierced part 25 to be out of its position at an angle and out of contact with the drive shaft 30.
    This allows the easy and fast removal of the drive shaft 30. The stop member 23 is movable in a third position in which the abutment member 23 is in contact with the drive shaft 30 allowing the locking of the stand 10 on the drive shaft 30.
    This makes it possible to have a second level of blocking. The abutment member 23 is positioned laterally with respect to the barrel 13 of the stand 10.
    This allows quick and easy access to this abutment member 23, while allowing its displacement to come into contact with the drive shaft 30 according to a displacement perpendicular to the longitudinal axis of the drive shaft 30. The abutment member 23 is at least partly threaded so as to be screwed at a threaded hole 23a formed in the barrel 13 of the stand 10.
    This allows its precise movement and its maintenance in a chosen position.
    At least a portion of the pierced part 25 is placed in a vice between the abutment member 23 and the return member 24.
    This makes it possible to exert a torque on the pierced piece 25 which reflects this torque on the drive shaft 30.
    The pierced part 25 comprises at least a first 25a and a second face 25b, the first face 25a being opposite the second face 25b, and the second face 25b being in contact with the return member 24, and in which the pierced piece 25 is positionable in a rest position and a working position, said rest position corresponding to a position of the pierced part perpendicular to the longitudinal axis of the drive shaft 30, and said working position corresponding to a position of biasing the pierced part 25 with respect to the longitudinal axis of the drive shaft 30 and contacting the drive shaft 30, and wherein in the rest position the first face 25a of the pierced part 25 is in contact at least in part with a conical portion of the abutment member 23 so as to ensure the biasing of the pierced part 25 and its contact with the drive shaft 30 lor sque stopping member 23 is moved from its second position to its first position.
    In the rest position, the first face 25a of the pierced part 25 is in contact with a portion of the first portion (surface 26a) of the cavity 22 and the second face 25b of the pierced part 25 is in contact with the body in this rest position, the main dimension of the pierced piece 25 is perpendicular to the longitudinal axis of the drive shaft 30 so as to allow it to be introduced or withdrawn through the bore 25a of the Moreover, in this rest position, the first face 25a of the pierced part 25 is in contact at least in part with a portion of the conical surface of the abutment member 23 so that when the it is screwed, it comes gradually tilt the pierced part 25 so as to put it at an angle and in contact with the drive shaft 30.

In order to increase the reliability of the locking of the stand 10 on the drive shaft 30, the abutment member 23 is then moved to its third position so as to be in contact with at least one surface of the axis d Since the displacement of the abutment member 23 is perpendicular to the longitudinal axis of the drive shaft 30, this bringing into contact then reinforces the blocking phenomenon already induced by placing the pierced part at an angle. 25.
    FIG. 4a illustrates, according to one embodiment, a profile view of a handle according to the present invention. In this figure the stand 10 is disengaged from the drive shaft 30, and the connecting device 20 is housed in the cavity 14 of the shank 13 of the stand 10.
    FIG. 4b, again according to this same embodiment, shows an enlargement of the connection device 20 in this situation.
    Advantageously, in a disengaged position, the pierced part 25 is in the rest position, that is to say in a position perpendicular to the longitudinal axis of the drive shaft 30. In this rest position, the first face 25a of the pierced part 25 is then in contact with a surface of the first portion of the cavity 22.
    This contact surface advantageously makes it possible to keep the pierced part 22 in the cavity 22.
    In FIG. 4b, the abutment member 23 is in its second position, that is to say, allowing the withdrawal of the drive shaft 30 of the stand 10, as well as its insertion. The abutment member 23 has a portion then located outside the hole 23a projecting from the barrel 13 of the stand 10.
    The present invention also relates to a method of mounting and dismounting a handle according to the present invention. Indeed, by its clever design, the present invention allows to mount a handle in a minimum of time. Indeed, it is sufficient to move the abutment member 23 in its first position and introduce the drive shaft in the shaft 13 of the stand through the connecting device 20, to push the handle against the door leaf until 'to the desired position.
    Advantageously and in order to save time during the installation of the present invention, the abutment member 23 is already positioned according to its first position when it is delivered to the installation site, this positioning operation having been made in the factory during the manufacture of the present invention for example.
    In this position, a self-locking effect takes place thanks to the use of the connection device 20. A stronger blocking can be achieved by moving the abutment member 23, screwing it in the case of a needle screw 23, for example until contact with the drive shaft 30.
    Regarding disassembly, it is just as easy, fast and requires only a few steps. It suffices to move the abutment member 23 towards its second position, by unscrewing it in the case of a needle screw 23 so as to release the drive shaft 30 by releasing the pierced part 25 from its working position. Therefore, the stand 10 can be removed from the drive shaft 30.
    The present invention thus provides a quick and reliable solution to the problem of mounting and dismounting door handle.
    The present invention is not limited to the previously described embodiments and extends to all the embodiments covered by the claims.
