Definitions

the invention relates to a locking fitting, in particular a bolt-lock, for door, window or the like, comprising a control mechanism provided with at least one follower acting on one or more locking elements such as a latch bolt and / or an operating rod, this follower being subjected to return means elastic to ensure its systematic return to the initial rest position, said elastic return means being constituted by a rack associated with a spring and with which the follower cooperates by means of appropriate teeth.
the present invention will find its application in the field of hardware building.
this control mechanism it is housed in a case and essentially comprises a follower provided, in its center, with a opening capable of accommodating the operating square with a handle accessible to the user.
this follower intervenes, with the aid of appropriate transmission members, on the locking elements.
this fitting of lock is also equipped with elastic return means capable of acting on the follower, precisely, in order to bring it back, systematically into its position angular occupied at rest.
Such elastic return means are constituted by a spring acting on a rack on which the follower meshes with a appropriate teeth arranged around its perimeter.
the spring constituting, in part, the elastic return means is defined, precisely, so that he is able to maintain said operating handle in this position of rest, namely horizontally.
the couple that its weight tends to decrease, while the return force of the spring increases gradually. This means that gradually by deviating from this position horizontal rest, the pressure that should be applied to the operating handle increases. This can be a real annoyance for some users, for example, for children or the elderly.
the present invention proposes to remedy all of the drawbacks cited above.
it aims to allow this handle to move, leaving from the rest position, and in at least one of the directions of rotation, to pivot according to a greater amplitude angle without this, however, resulting in a profound modification of the parts of the control mechanism or even by a amplification of the movements of the rack constituting, at least partially, the elastic return means in the rest position of the follower and, therefore, of the handle maneuver.
This invention also makes it possible to respond to the problem of the increase in resistance provided by the operating handle during rotation.
the invention relates to a locking fitting, in particular, a locking lever, for door, window or the like, comprising a control mechanism provided at least one follower acting on one or more locking elements such as a U-bolt and / or an operating rod, this follower being subjected to means of elastic return ensuring its systematic return to the initial rest position, said elastic return means being constituted by a rack associated with a spring and with which the follower cooperates by means of suitable teeth, characterized by the fact that the rack has a toothing which beyond a initial displacement phase of this rack is able to multiply the movement of the latter relative to the rotation of the follower in at least one direction.
the present invention is relating to a locking fitting 1 for door, window or the like 2.
this locking fitting 1 can be in the form of a lock-bolt of an embodiment in accordance with FIG. 2 of this appended drawing.
the present invention is in no way limited, nor to such an embodiment a lock-bolt, or even this particular type of locking fittings since it is able to find its application in many other conceptions of locking fittings.
a locking fitting has a housing 3 containing a control mechanism 4 and disposed on the opening 5 of said door, window or analog 2.
the control mechanism 4 during an action of use on an operating handle 6 acts on locking elements 7, 8 intended to cooperate with keepers (not shown), located in correspondence on the frame sleeping 9.
this control mechanism 4 is provided, in particular, with a follower 10 having, in its center, an opening 11 adjusted to the section of the square of the handle more precisely, the action of the user on this operating handle 6 results in a rotation of the follower 10 which, thanks to transmission members 12, 13 appropriate, transmits its movement to one or more of the locking elements 7, 8, either directly, for example, by a latch bolt, or through pieces intermediaries 14, such as an easel 15, itself transmitting its movement to one or several operating rods fitted with locking plates and / or rollers or others.
the transmission members 12, 13 have the function of transmitting to the elements of locking 7, 8, the movement printed on the follower 10 in a well-determined order and, this, according to the direction of rotation, precisely, communicated to this follower 10.
empty strokes 16 are arranged between these transmission members 12, 13 and the follower 10, precisely, depending on the desired result.
the opening 5 of the door 2 comprises a glazed part 23, itself opening insofar as it is mounted by by means of articulation means 24 on a frame 25 defined, substantially, by said opening 5.
the operating handle 6 extending, substantially, in front of this glazed part 23, obstructs the opening. However, if one could tilt this maneuver handle 6 enough to bring it back, in this specific case, in a vertical or almost vertical position, it would be possible to open this glazed part 23.
control 4 does not allow rotation of such amplitude of the handle maneuver 6 so that lowered or raised, it remains a discomfort at the opening of the part glazed 23.
the solution may, of course, be to modify the control mechanism 4 by amplifying, consequently, the empty strokes 16 of the follower 10 relative to the transmission members 12, 13, but also by amplifying the movements and, therefore, the size of the pieces of the elastic return means 18.
the solution according to the invention consists in equipping the rack 19 with a toothing 26 which either capable of causing a reduction in the movement of the rack 19 beyond an initial displacement phase, this with respect to the rotation of the follower 10 in at least one sense.
the toothing 26 capable of fulfilling the desired function has a or more teeth 27 on which one or more meshes at the end of the stroke, the follower 10 and which are of increased size leading to a reduction in the nominal diameter 28 of the wheel tooth that constitutes the follower 10.
toothing 20 of this follower 10 also has one or more teeth 29 able to cooperate with the specific teeth 27 of the rack 19.
this toothing 26 of the rack 19 may also include several teeth of gradually increasing in size so that the nominal diameter 28 of the toothed wheel constituted by the follower 10 tends to decrease progressively during rotation of this last. This therefore makes it possible to compensate for the gradual increase in the return force of spring 21 so that the resistance provided at the handle maneuver 6 is substantially constant.
