    [0001] Returnable Control Knob
    [0002] Object of the invention
    [0003] It is a returnable control command, for the control of electrical signal by means of a potentiometer, switch, encoder or similar, of the type used in controls of electrical / electronic equipment.
    [0004] This control incorporates an internal mechanism with a strap placed on a carrier and which links the housing to the electrical signal on the one hand, and so, in its initial position or point 0, this strap meets a minimum tension to avoid gaps, but when acting on the control, whose angle of rotation is limited, the strap enters the load in the opposite direction to the rotation, in such a way that, at the end of the force that caused the rotation, the command returns to its initial resting position or point 0, and being prepared for a new performance.
    [0005] This device provides a different sensation to the touch in relation to the actuation of this type of controls, while allowing the device to be placed independently of the control rod, where this control rod can be introduced into the mechanism by either side without Need for disassembly.
    [0006] This invention has its field of application in the electronics and home appliances industry.
    [0007] Background of the invention
    [0008] The usual system of actuation of the control commands of electrical / electronic equipment, such as an appliance, is that the final position of the control determines the intensity of electrical current that allows it to pass to the corresponding equipment depending on the user. Although it is the most widely used method today, many people tactically prefer a control device of an appliance that works sequentially, that is, that the position of the control is always in its resting position, except for the moments in which you are acting on him.
    [0009] In order to achieve this effect, solutions such as the one provided in patent EP1627394 are proposed for 'Haptic limitation for a rotary switch or a potentiometer' which refers to a housing configured to accommodate a helical spring that is coupled by its lower arm to a stop lower and its upper arm is housed in a recess in the housing; This spring is prestressed in its initial position and includes both a radial and axial component, whose upper recess of housing of the spring is included in an angle between 25 and 65 °, with no other function than to accommodate the upper arm of the spring.
    [0010] The use of helical springs supposes a space necessary for its considerable accommodation if the total volume of the device is taken into account, since the free ends of the spring are located in separate housings in different planes of the device; which on the one hand means an increase in volume and on the other makes the operation of its placement more complicated. On the other hand, for relatively small diameters of these springs, the union of the helical part with the free ends (normally projected perpendicularly to the diameter of the propeller) is extremely fragile, which is why the control devices that use this type of Helical springs are bulky.
    [0011] Likewise, to date, the control device is assembled together with the control rod, as it is part of the actuation mechanism, that is, once mounted, the mechanism stem cannot be replaced independently. On the other hand, the rod can only be inserted in its housing of the actuation mechanism on one side, so that each mechanism is designed to be used with the rod on its corresponding side, without allowing the same mechanism to be used interchangeably on either side.
    [0012] In document GB1300947A for 'an electrical control device' and US3952278A for 'combination of a switch and variable resistance', to achieve the return of the command to its 0 or rest position, 'resilient' means are used that return the command to An initial position. As can be seen in these documents, one or more 'needles' are observed which are inserted at the end of the shaft through a pin and whose ends are housed in recesses in the housing. Shaft that fits into the actuator in such a way that when the actuator is rotated, the shaft is dragged and deformed elastically until the rotating force ceases, at which point the 'resilient' needle returns its energy to the actuator returning it to its original position.
    [0013] These needles have to be fixed in their assembly with pressure in order to facilitate the deformation of the same during the operation of the control, which entails greater assembly operation, with greater precision and elements of great precision, which makes these systems more expensive and with greater possibility of failures.
    [0014] Description of the invention
    [0015] In order to provide a global solution to all the previously described drawbacks, a returnable control knob is described below, which is based on a return mechanism at point 0, composed of a strap housed in a carrier between two brackets and two portafleje stops, a housing with two other housing stops inside that limit the displacement of the strap in its operating position and an electrical signal controller, requiring a drive rod for final use.
    [0016] An encapsulation of the same strap is created between the carrier and the housing, defining an area where this strap moves and rotates.
    [0017] The strap has two pins in its free terminations, which are projected radially and are the ones that contact the interior between the supports of the carrier, developing the strip between these supports of the carrier and the guide passage of the actuator. In this position the strap is maintained with some preload in order to avoid any slack between the pieces. In this mechanism, a turning movement is contemplated both to one side and to the other, where the strap adopts a determined arrangement between the brackets of the carrier to the point 0 return mechanism with a centering hole of the mechanism.
    [0018] Likewise and in accordance with the above, the housing stops are arranged on the inside, whose angle with respect to the axis of rotation, is equal to that formed by the holders of the carrier, in such a way that the strap pins are housed between the carrier supports and housing stops.
    [0019] On the other hand, the portafleje houses some stops of portafleje, in such a way that in its turn around its axis it contacts the inner stop of the housing. That is to say, at the maximum angle of rotation of the actuator of the mechanism is that between the resting position of the mechanism and the rotation that brings the inner stop of the housing into contact with the stop holder.
    [0020] With the aforementioned it is understood that the angle of action of the mechanism depends on the dimensions of these stops - of housing and of the carrier -, that is, the larger the longitudinal dimension of these stops the angle of action will be reduced, and inversely, if these dimensions are reduced the angle will increase, so that the turn necessary to activate the associated electric signal controller type potentiometer, switch, encoder or similar will be greater, all depending on the conditions and interest of use.
    [0021] In the maximum working position, in which a rotation has been made on the actuator by rotating the rod and the carrier; This carrier, in its turn, drags the strap pin with which it has contact by means of the corresponding carrier of the carrier, until the holder stops sticking with the corresponding stop of the housing, this being the maximum angle of rotation of the device. In this position the strap is loaded since in this movement one pin approaches the other strap pin, because the latter is retained by one of the housing stops; in turn, the electrical signal controller receives the action command during this position.
    [0022] Once the force or torque that caused the turn is finished, the strap returns the torque in the opposite direction to the actuator to its rest position or point 0.
    [0023] The assembly is completed with a potentiometer, switch, encoder or similar type electrical signal controller, which is coupled to the carrier by means of an coupling, through which the actuator stem runs and in turn meshes with the rotor of the electrical signal controller . The section of this actuator is adjusted to that of the coupling in order to allow acting on the strap in a manner integral to the entire mechanism; for this, the section of the guide step of the electric signal controller and that of the carrier are corresponding to allow the passage and housing of the actuator stem.
    [0024] In turn, the actuator rod can also configure an actuator stop that prevents excessive actuator penetration into the mechanism, which contacts the pole of the carrier, and identifies a unique position.
    [0025] From the above it follows that the plane in which the strap is developed is the same as that of the stops of the carcass and the carrier, so that the use of more bulky parts and complications is avoided when it comes to mount the helicoaxial spring in position.
    [0026] The same actuator is coupled and is operative both on one of the fronts of the return mechanism object of the invention and on the other, in such a way that, this actuator can be placed once the device is installed, depending on the operation of the command where be located. To do this, the parts that make up the stem passage, such as the guide passage, housing hole, coupling of the carrier and rotor of the electric signal controller they allow the rod to penetrate the same length both in one direction and in the opposite in relation to the axis of the passage.
    [0027] Advantages of the invention
    [0028] The use of the returnable control command object of the present invention provides a series of advantages in relation to what is known so far, such as:
    [0029] - By placing all the actuation elements of the return mechanism to the 0 or initial point in the same plane, the volume of the device is reduced to the minimum expression.
    [0030] - It facilitates the assembly of the mechanism.
    [0031] - For the assembly of the mechanism, it is not necessary to pre-assemble the actuator, so that it is pre-assembled in its final location.
    [0032] - The actuator can be mounted interchangeably on either side, so it is not necessary to have an actuator mechanism operated on one side and another for an actuator operated on the other side.
    [0033] - The maximum angle of action can be modified by simply replacing the carrier and / or the housing with another one with different stops: longer, shorter and / or offset from the first.
    [0034] The person skilled in the art will readily understand that he can combine characteristics of different embodiments with characteristics of other possible embodiments, provided that such combination is technically possible.

    [0045] Preferred Embodiment of the Invention
    [0046] The constitution and features of the invention may be better understood with the following description made with reference to the attached figures.
    [0047] Figure 1 shows in detail the arrangement of the different elements that make up the returnable control knob, object of the present invention, for this part of a housing (1), which houses the carrier (2), a strap ( 3) and an electric signal controller (4) (in the figure representing a potentiometer), through which the rod (5) of the actuator (6) runs. In the housing (1), housing stops (7a and 7b, figures 4 to 7) and a centering hole (13) of the return mechanism to point 0 are distinguished.
    [0048] In the portafleje (2) there are some portafleje supports (8a and 8b) and some stops of portafleje (9a and 9b), with a coupling (10) to establish a unique position with the electric signal controller (4), for rotor medium (16) with which it meshes. This strap (3) is essentially circular, adopting pins (11a and 11b) developed radially with respect to the axis of the circle that would make up the strap (3). In turn, a guide passage (12) for the rod (5) is configured inside the carrier (2).
    [0049] For its part, the actuator (6) can form an actuator stop (14), which would contact the post (15) of the carrier (2). The section of the rod (5) corresponds to the section of the guide passage (12) in order to create a joint assembly, and that from the actuator (6) the actuation of the electric signal controller (4) is allowed as well as from the return mechanism, return the actuator (6) to its position of point 0.
    [0050] Figure 2 represents the strap (3) in its resting position, resting its pins (11a and 11b) on the respective carrier holders (8a and 8b), these pins (11a and 11b) being placed in the same plane as the body of the strap (3).
    [0051] In Figures 3 and 4, it can be seen that the same actuator (6) is operative both from one of the fronts of the return mechanism object of the invention and from the other, so that this actuator (6) can be placed Once the device is installed, depending on the control options where it is located.
    [0052] In figures 5 and 6, it is shown what constitutes the return mechanism at point 0, distinguishing the relative position of the strap (3) with respect to the housing (1) and the carrier (2), where the pins (11a, 11b ) of the strip rest on the inside of the respective carrier holders (8a, 8b), so that in this position, the strip (3) exerts some pressure by means of the pins (11a, 11b) on these carrier holders (8a, 8b) generating a preload, which being distributed between the two pins (11a, 11b) equally, no movement of the mechanism is created. This is the resting position of the actuator or point 0, in which no action is being exerted on the electrical signal controller (4), and all the elements are in equilibrium and the strap (3) is encapsulated between the housing (1) and the carrier (2).
    [0053] Figure 7 shows the return mechanism at point 0 of the returnable control knob, object of the present invention, in maximum working position, in which a rotation has been made in the direction of the arrow (X) on the actuator (6), rotating the rod (5) and the carrier (2). This carrier (2), in its turn, draws the pin (11b) of the strap (3) in contact by means of the corresponding carrier of the carrier (8b), until the carrier holder (9b) sticks with housing stop ( 7b), this being the maximum angle of rotation of the device. In this position the strap (3) is loaded since in this movement the pin (11b) approaches the pin (11a), since the latter is retained by the housing stop (7a); in turn, the electrical signal controller (4) receives the action command during this position.
    [0054] Once the force or torque that caused the rotation in the direction of the arrow (X) is finished, the strap (3) returns the torque in the opposite direction moving to its rest position or point 0 as shown in Figure 4. In figure 8, the turning movement is carried out in the direction of the arrow (Y) with the pin (11a) of the strap (3) being moved by the carrier of the carrier (8a) until the holder of the carrier (9a) contacts the housing stop (7a), thus limiting its movement, at the same time that the electric signal controller (4) is activated in the opposite direction to that exerted in the previous case with the rotation in the direction of the arrow (X). The return to position 0 is made thanks to the release of the tension accumulated in the strap (3) during the rotation in the direction of the arrow (Y).
    [0055] As described above, with the position device of a returnable control knob, object of the present invention, it is guaranteed that once the actuator (6) has been operated and the electrical signal controller (4) activated according to the interest of the user, the command returns to its resting position or point 0.
