Definitions

  • the present invention relates to a rotary friction control, mounted in a device in which friction means are interposed between a control shaft and a train, the rotary friction control comprising at least one elastic open ring ensuring a connection between a rotary element leading and a rotary driven element coaxial with the driving element, while allowing a separation in rotation of an element relative to the other, said elastic open ring having a part immobilized in rotation, around the geometric axis of the elements leading and driven, on one of these elements, and said elastic open ring being applied internally against the peripheral flange of a wheel constituting the other element.
  • This invention is applicable in particular, but not exclusively, to the manual control of a timer or a programmer, designed for the selection of a time or a program.
  • any timer device or other similar mechanical or electromechanical system, such as a programmer comprising a gear train or regulator as well as a program cam secured to a control axis
  • a programmer comprising a gear train or regulator as well as a program cam secured to a control axis
  • Another solution currently used comprises a “C” ring which takes place in an annular groove of a wheel, and which clamps the wheel around an axis, this allowing the wheel to be integral in rotation with the axis up to a certain torque, and to slide relative to the axis beyond this torque.
  • This solution is simple from the constructive point of view, but it has a limit of use in temperature which is relatively low, of the order of 85 ° C., which reduces its field of application.
  • a solution similar to the previous one, disclosed by document DE-B-1255746, is a rotary friction control with an elastic open ring of generally triangular appearance, mounted between a driving rotary element and a coaxial driven rotary element, and being in friction contact with these two elements, being applied externally to one of the axis-shaped elements, and internally against a flange of the other element, of hollowed-out conformation.
  • a certain "rotational connection" between the elastic open ring and one of the rotary elements it can be seen that this connection is not positive.
  • the friction torque is not precisely controlled, and as already indicated above, correct operation is not guaranteed at all temperatures.
  • a toothed wheel is clamped between a spring washer, integral with the axis, and a plate fitted on the same axis; two washers allow the wheel to slide relative to the spring washer and plate, during manual action on the control shaft.
  • This solution allows operation at a higher temperature, but it is expensive because of the need for a larger number of parts.
  • the present invention aims to eliminate these drawbacks by providing a rotary friction control of the type indicated in the introduction, improved in particular from the point of view of the smoothness and precision of the manual control, therefore increasing what may be called the Selection "comfort”, while offering a simple and economical solution in terms of construction and assembly, thanks to a positive connection between the elastic open ring and one of the driving and driven elements.
  • the elastic open ring has a central part immobilized in rotation but not in translation on one of the elements by retaining means integral with the 'control axis, and two symmetrical branches applied internally against the peripheral flange of the wheel.
  • the middle part of the open ring is substantially rectilinear when the open ring is in the free state, this middle part being deformed and arched, in a direction corresponding to the spacing of the two branches, when it is engaged on the retaining means integral with the control shaft.
  • the two branches of the ring open in the free state are part of a circle whose radius is substantially equal to the inner radius of the peripheral flange of the wheel.
  • the open ring is thus positioned by its middle part, immobilized in rotation relative to the control axis but which can describe a slight translation, the mounting of the open ring therefore being "floating".
  • the two branches of the open ring spaced from one another during the mounting of this open ring on the control shaft, are reconfigured according to the initial circle when the wheel is put in place. Thanks to this conformation and to the floating assembly, the open ring exerts by its two "armed" branches a pressure equally distributed on the inner face of the peripheral rim of the wheel.
  • the means for retaining the middle part of the open ring comprise two symmetrical pairs of studs, and an intermediate stud, carried by a disc-shaped part of the control axis; these studs are arranged so as to impose on the middle part of the open ring the desired deformation, putting the two branches in tension, while allowing a slight translation of this middle part.
  • the disc-shaped part of the control shaft has two openings provided respectively for the passage of two positioning pins which, in a mounting phase of the rotary friction control according to the invention, provide a temporary holding of the two arms of the ring open in the closed position.
  • the wheel When the wheel is mounted, it covers the disc-shaped part belonging to the control axis, trapping the open ring.
  • the wheel has a central hub which cooperates with at least one clipping lug belonging to the control axis, so that an assembly is obtained at the end of assembly, all of the elements of which are well joined together. others and involve minimal risk of separation.
  • this relates to a rotary friction control, of the type indicated in the introduction, in which the elastic open ring has at least one end curved inwards, and this end is engaged in a notch of one of the elements, such as disc.
  • This other embodiment involves an open ring of asymmetrical configuration, making it possible to have a lower sliding torque for the rotation of the control axis in one direction, and a higher sliding torque for the rotation of the axis. control in the opposite direction, while ensuring by a very simple means the connection in positive rotation between the open ring and one of the elements.
  • the peripheral rim of the wheel, with which the open ring cooperates, can be notched which regulates the handling and ensures precise angular positioning.
  • the elastic open ring can have a square or rectangular section, more or less flat, or a circular section or elliptical, the torque required to obtain the sliding varying according to the shape of the open ring.
  • the rotary friction control is composed of three distinct elements, namely a control axle 1, a wheel 2 and an elastic open ring 3.
  • the control axle 1 and the wheel 2, mounted along the same geometric axis A, can be made of a relatively rigid synthetic material.
  • the control axis 1 has a shaft end 4 having a flat 5, designed to receive an operating button not shown, and a disc-shaped part 6. On the face of this part 6 facing the wheel 2, are formed several. studs used to position the open ring 3, in a manner which will be specified below.
  • the wheel 2 has a peripheral flange 7 and a central hub 8. In the mounted position, as shown in FIG. 1, this wheel 2 comes to cover the disc-shaped part 6 of the control axis 1, by trapping the ring open 3. The central hub 8 of the wheel 2 is then retained axially by a clipping lug 9 belonging to the control axis 1.
  • the open ring 3 which here has a flattened rectangular section has a middle portion 10 and two curved symmetrical branches 11, the free ends 12 are themselves curved inward.
  • the middle part 10 of the open ring 3 is substantially rectilinear, and its two branches 11 are inscribed in a circle of radius R.
  • the disc-shaped part 6 of the control axis 1 carries two symmetrical pairs of studs 13, 14 and an intermediate stud 15, located between these two pairs.
  • the open ring 3 is positioned on these pads, passing between the two pads 13,14 of each pair and pressing against the intermediate pad 15, so that the middle part 10 of said ring is deformed and arches.
  • the two branches 11 of the open ring 3 are then spaced from one another.
  • the two branches 11 of the open ring 3 are again brought closer to one another, and they are held in the tightened position by means of two positioning pins 16 , introduced through two respective small openings 17 formed in the disc-shaped part 6.
  • the wheel 2 is placed on the control shaft 1, and the positioning pins 16 are removed from the openings 17, so that the branches 11 of the open ring 3 are released.
  • the two branches 11 of the open ring 3 substantially resume the initial configuration forming part of a circle of radius R, but these two branches 11 are put under pressure against the inner face of the peripheral edge 7 of the wheel 2.
  • the open ring 3 is thus positioned on the disc-shaped part 6 of the control axis 1, being immobilized in rotation on this part 6 while being able to describe a slight translation in the general direction of its middle part 10 Thanks to this "floating" arrangement of the open ring 3, leading to self-centering, the two branches 11 of the latter exert a pressure equally distributed on the peripheral flange 7 of the wheel 2.
  • the curved ends 12 of the two branches 11 improve the sliding of these branches against the inner face of the rim 7.
  • the open ring 3 has a circular section, while retaining the same general appearance with a median part 10 substantially straight in the free state, two curved symmetrical branches 11 and curved ends 12
  • the circular section is advantageous in that it avoids parasitic friction which could disturb the constancy of the friction effect.
  • FIGS. 8 and 9 show another embodiment, using an elastic open ring 3 of circular section, with only one clearly curved end 18.
  • the open ring 3 is mounted between a disc 6 and a wheel 2 provided with a flange peripheral 7, this open ring 3 being made integral in rotation with the disc 6, by engagement of its end 18 in a notch 19 of the disc 6. Beyond a given torque value, the wheel 2 and the disc 6 disengage by sliding the open ring 3 against the inner face of the peripheral flange 7 of the wheel 2.
  • the use of an asymmetrical open ring 3 here makes it possible to have a different sliding torque value, depending on the direction of rotation .
  • the embodiment according to Figures 8 and 9 may give rise to variants, in particular by replacing the elastic open ring 3 of circular section with an open ring of rectangular section, or alternatively by replacing this single open ring of circular section by two or several joined elastic open rings of circular section but of smaller diameter.
  • the open ring 3 can be produced in an elastic material such as spring steel or bronze, or in the form of a "piano cord", this latter embodiment applying to open rings of circular section according to FIGS. 7 to 9.
  • the rotary friction control described above applies in particular to the functions of manual selection of a time or a program, in a timer or a programmer, the control axis 1 being linked to a selection button while the wheel 2 is the first element of a cog.
  • the asymmetrical embodiment according to FIGS. 8 and 9 makes it possible, in this type of application, to have a lower torque when the control axis is rotated in one direction to select a time delay, hence a comfort of use, and having a stronger torque on return, to contain the action of the driving force on friction.
  • the inner face of the peripheral rim 7 of the wheel 2, cooperating with the open ring 3, can be smooth or notched as shown at 20 in FIG. 9.
  • the smooth shape gives the handling a take-off effect followed by sliding, while the notched configuration provides convenience in handling which then appears regular, while ensuring angular positioning, which in certain applications constitutes an appreciable additional advantage.
  • the smooth shape is suitable for handling at maximum temperature of around 85 ° C, while in the notched variant, the appropriate configuration of the elastic open ring 3 and the flange 7 of the wheel 2 is particularly suitable for handling at temperature high, of the order of 125 ° C.
