    [0001] The configurations described here generally refer to side control levers that are usefully provided as an operator interface for a variety of devices in order to allow an operator to make several manual control inputs. Description of the state of the art
    [0002] The side control levers (more simply known in the art as "sidesticks" or "joysticks") have been widely used in several industries for the control of heavy machinery, vehicle construction, tractors, submarines, simulators and, of course, aircraft. The introduction of side control levers within the aerospace industry occurred primarily for military applications, such as providing pilot control inputs for fighter planes, helicopters, airplane simulators and remotely controlled aircraft (drone). In addition, both the commercial and general aviation industries have realized the advantages of replacing conventional centrally mounted control sticks with side control levers to provide increased visibility of instruments on an aircraft instrument panel as well as increased physical space for pilots. The use of side control levers in the aviation industries in addition to military aviation was thus only possible when the space cable's electric cable control system technology became available for non-military aircraft.
    [0003] One of the most challenging aspects that engineers and designers face when developing side control levers for non-military aircraft lies in providing the appropriate ergonomic features for such side control levers considering that their locations in relation to the pilots and the magnitudes of force are significantly different when compared to well-known aircraft control joysticks. More specifically, as its name implies, a side control lever is located physically on the aircraft's side console and is intended to be controlled via only one pilot arm while a control stick is physically located in front of the pilot and can be controlled promptly by both arms. Consequently, the braking force and the master gradient on the side control levers are significantly lower when compared to conventional control sticks.
    [0004] Equally important for achieving a harmonic application of the side control levers in terms of ergonomics and handling quality are the comfort and accessibility of triggers of important system functions, such as quick-disconnect function of the autopilot, control priority (ie, take control priority to the side control lever while the opposite side control lever is inactive), PTT (push to talk) and similar communication functions. The side control levers as revealed here are therefore aimed at providing superior ergonomics and handling quality in terms of operator comfort and accessibility for various system functions. Objectives and brief description of the invention
    [0005] According to one configuration, the side control levers will comprise a base, an elongated column lever extending upwardly from the base, a head on a part of the upper end of the control column, and a thumb support surface if extending laterally and upwards in relation to the control column. The support surface of the thumb can be supported through a concave support wall extending outwardly that joins the support surface of the thumb on a generally sinuous edge. In this context, the generally sinuous edge may extend generally convexly outward from a lower region in the control column to a region of the convex apex, and then extend from the vertex region generally upward and concave to an upper region. this in the head. The support surface of the thumb can be concave to facilitate comfort.
    [0006] The head of the side control lever may include a separating face surface defining the inner and outer face surfaces disposed laterally adjacent to each other. According to some configurations, the inner face surface is arranged at an elevation that is lower than the outer face surface. The internal and external buttons can thus project externally from the surfaces of the internal and external faces, respectively. More specifically, some configurations will include an inner face surface that is arranged at an elevation that is lower than the inner face surface so that the inner button is positioned in an inner recess fit defined by the inner face surface and a pair of walls lateral and top in L shape. The inner and outer face surfaces can be joined together at one rear end of them, and deviate forward in relation to each other so that the inner face surface is at an elevation lower as compared to the outer face surface.
    [0007] An advanced button and / or side button can extend outward from the head and laterally from the thumb support wall to promptly provide pilot control of the other functions of the aircraft system.
    [0008] Some configurations of the side control lever will comprise an elastomeric material covering at least part of the control column. The base may also include a concave widened support surface that can be stretched in a rear direction.
    [0009] Another configuration of the side control lever will comprise a base, an elongated control column extending upwards from the base, and a head at a part of the upper end of the control column, where the head includes a split face surface. defining surfaces of the internal and external face arranged laterally adjacent to each other with the surface of the internal face being at an elevation that is lower than the surface of the external face. The internal and external buttons can, in this way, be provided that project outwards from the surfaces of the internal and external faces, respectively.
    [0010] The aircraft and other devices that require user manual control inputs (for example, heavy machinery, system simulators and the like) can thus be provided with one (or more) side control lever. When fitted on an aircraft, a pair of reflected images from the side control levers are likely to be present, one being the pilot's left hand lever and one being the pilot's right hand lever.
    [0011] These and other aspects and advantages will become clearer after careful consideration is given to the detailed description below of the preferred exemplary achievements of this. Brief description of the drawings
    [0012] The revealed configurations will be better and more fully understood in reference to the following detailed description of the exemplary and non-limiting illustrative achievements in conjunction with the drawings of which: FIGURE 1 is an ocular view of the pilot from an aircraft cabin in which the pilot (left hand) and co-pilot (right hand) control levers are provided according to a configuration; FIGURE 2 is a perspective view of the right side of the pilot's side control lever (left hand) shown in FIGURE 1; FIGURES 3 and 4 are front and rear elevation views, respectively, of the side control lever shown in FIGURE 2; FIGURE 5 is a top plan view of the side control lever shown in FIGURE 2; FIGURES 6 and 7 are elevational right and left side views, respectively, of the side control lever shown in FIGURE 2; and FIGURES 8 and 9 are front and rear elevational views of a side control lever according to another configuration. Detailed description of the figures
    [0013] The accompanying FIGURE 1 represents an ocular view of the pilot of an example of the aircraft's AC cabin environment in which the aircraft's controls and instrumentation are located. As can be seen, the side control levers of the pilot (left hand) and co-pilot (right hand) SS1 and SS2 (here sometimes more simply referred to as side levers) are positioned on the left and right side consoles CL, CR of the cabin AC adjacent to the pilot and co-pilot seats PS1, PS2, respectively. A flexible protection FS1, FS2 can be provided with each of the side levers SS1, SS2 in order to visibly hide their mechanical and electrical connections. As can be seen, the CP control panel is unobstructed by the side levers SS1 and SS2 due to the lateral positioning of the PS1, PS2 seats on the CL, CR consoles, respectively, thus providing pilots with greater visibility of the aircraft instrumentation.
    [0014] It will be understood that, while reference will be made to an aircraft control side lever, several other uses and apparatus may similarly be provided with a control rod as described here. Thus, reverence for a side aircraft control lever should be understood as a reference to a presently preferred realization that is not limiting to its possible end uses.
    [0015] FIGURES 2-7 represent in more detail the pilot's side lever (left hand) SS1, it being understood that the co-pilot's side lever (right hand) SS2 is substantially a reflected image of it. Thus, the discussion below regarding the SS1 pilot's side lever is similar and pertinent to the SS2 co-pilot's side lever, but will not be discussed in greater detail for the sake of clarity.
    [0016] The side lever SS1 is generally comprised of an upper head 10, a control column 12 and a lower base 14 that are configured so that a pilot's left hand can fit comfortably to it when the side lever is gripped during use (see FIGURE 2). A support surface of the thumb 16 extends laterally outward and upwards relative to the control column 12. As shown, for example, in FIGURE 3, the support surface of the thumb 16 is supported by a concave support wall extending outward 16b joining the supporting surface of the thumb to a generally sinuous side edge 16a. The edge 16a extends generally convexly outwardly from a lower region 16a1 of this in the control column 12 to a region of convex apex 16a2 and then generally upward and concave to an upper region 16a3 of this in the head 10. The supporting surface thumb 12 is itself slightly concave in order to promote comfort.
    [0017] The head 10 defines a dividing face surface defining the slightly convex or substantially flat internal or external (in relation to the pilot) face surfaces 18, 20 disposed laterally adjacent to each other. The inner and outer surfaces 18, 20 are thus joined together at one rear end (in relation to the CP control panel) of these and then deviate forward from each other so that the previous one is at an elevation that is lower in relation to the last. The inner and outer surfaces 18, 20 include buttons 18a, 20a protruding outwardly from them. The button 18a can, for example, serve to provide quick disconnection of the autopilot and / or to establish the priority of the side levers SS1 and SS2 (for example, to establish which of the side levers SS1 or SS2 is capable of providing active control inputs for the aircraft's attitude control surfaces), while button 20a can be used as a tactile control direction (TCS) button (for example, to allow a pilot to momentarily override the autopilot without disconnecting the autopilot to allow input of manual control (changes) of vertical speed). So, in order to allow a pilot a more tactile feel to identify the correct button among buttons 18a, 20a (and thereby minimize confusion about which button is being pushed), internal button 18a is at an elevation slightly lower as compared to the external button 20a due to the differential angular orientation of the respective face surfaces 18, 20.
    [0018] In this context, a tangent plane of each of the face surfaces 18, 20 is generally inclined upwards and forwards (in relation to the control panel CP) at different angles. The angle of inclination of the surface of the inner face 18 with respect to a horizontal plane is less than that of the surface of the outer face. In addition, the angular difference with respect to a horizontal plane between the inner and outer face surfaces 18, 20 is such that the flat top surfaces of the buttons 18a, 20a extending outwardly from the face surfaces 18, 20, respectively, they form an angle between them of about 10 ° to about 15 °, more preferably about 13 ° (± about 0.25 °).
    [0019] In use, a pilot will grasp the side lever SS1 so that the pilot's palm is physically placed against the control column 12 with the thumb positioned on and supported by the support surface of the thumb 16. The pilot will then be able to manipulate the thumb and fingers in order to access several system buttons presented by the side lever SS1. It will be observed in this context that the internal button 18a is located essentially in an internal recess fitting defined by the face surface 18 and the side and top walls 18b, 18c in an L shape joining the lower inner face wall 18 to the face wall upper outer 20. As seen, the side wall 18c tapers from its junction with the top wall 18b in a rear direction the junction of the inner and outer face surfaces 18, 20 so as to be generally triangular in shape ( despite having a slightly convex arched configuration). The recessed insert defined by the walls 18b, 18c is thus opened on its internal side (pilot) to allow the pilot's thumb to be easily moved from the support surface of the thumb 16 for access and operation of the button 18a. Similarly, the pilot's thumb can be properly positioned to allow access and activation of the button 20a detaching from the outer face surface 20, in which case the lower elevation of the inner face surface 18 in relation to the outer face surface 20 provides the pilot with tactile response of thumb positioning.
    [0020] The side lever SS1 also includes additional buttons 22, 24. As an example, button 22 can be provided as a push to talk (PTT) communication switch to allow radio communication when pressed, while button 24 can be provided such as an augmented vision switch (EVS) to allow the pilot to select the augmented view (for example, either the synthetic view or the infrared view) displayed on the instrumentation of the cockpit CP control panel. Button 22 pops out and forward (in relation to the CP control panel) in order to be manipulated by the pilot's index finger (second). The button 24 protrudes outwards and laterally downwards from the support wall of the thumb support 16b in order to be manipulated by the pilot's middle (third) finger.
    [0021] A concavely enlarged support surface 14a is provided on the bottom base 14 in order to provide support for the pilot's palm. As shown, for example, in FIGURES 5 and 6, the palm support surface 14a is elongated in the rear direction (in relation to the CP control panel) in order to provide increased support for the pilot's palm when holding the side lever SS1 .
    [0022] The outer surface of the side lever can be provided with any suitable tactile material. As an example, as shown by the embodiment shown in FIGS. 8 and 9 (which include the same numerical references in FIGS. 2-7 but defined through a primary annotation (') to illustrate similar structures between them), the control column 12' of the side lever SS1 can be provided with regions 12a in contact with the pilot's palm, which are formed of an elastic material of the rubber type, in order to provide a feeling of increased grip. Alternatively, a metallized surface can be provided with or without irregularities in the surface as desired.
    [0023] While the invention has been described in connection with what is currently considered to be the most practical and preferred configuration, it is understood that the invention should not be limited to the revealed realization, but on the contrary, it is intended to cover several modifications and equivalent arrangements included within spirit and scope.
