  A radio control transmitter for model control is generally provided with a stick lever unit for generating a control signal. The basic structure of a conventional stick lever unit will be described with reference to the schematic diagram of FIG. A first variable resistor 101 is provided outside the frame-shaped fixing member 100 that is fixed to the housing of the radio control transmitter. Inside the fixed member 100, a frame-shaped first rotating member 104 is rotatably supported by a shaft 102 of the first variable resistor 101 and a rotating shaft 103 concentric with the shaft 102. ing. A second variable resistor 105 is provided outside the first rotating member 104. Inside the first rotating member 104, a second rotating member 107 having a stick 106 is pivotally supported via a shaft 108 of the second variable resistor 105. Note that the wiring 109 of the first variable resistor 101 is connected to a control board (not shown), and the wiring 110 of the second variable resistor 105 is controlled after being pulled out beyond the frame wall of the fixed member 100. Connected to the board.

  The rotating shaft 103 of the first rotating member 104 (or the shaft 102 of the first variable resistor 101) and the rotating shaft of the second rotating member 107 (or the shaft 108 of the second variable resistor 105) are orthogonal to each other. Therefore, if the operator operates the stick lever 106 provided on the second rotating member 107 with his / her finger in any direction, the two variable resistors 101 and 105 are appropriately operated to rotate. Control signals are generated.

  Taking a radio controlled transmitter of a model airplane as an example, the model airplane has a rudder and an elevator for attitude control. These rudders are operated by two servo motors mounted on the airframe. If one stick lever unit provided on the radio control transmitter is assigned to control the rudder and elevator, the control signals of the two servo motors that drive the rudder and elevator are obtained by operating one stick. The attitude of the aircraft can be controlled.

  According to the conventional stick lever unit, when the first rotation member 104 to which the second variable resistor 105 is attached is rotated by operating the stick 106, the second variable resistor 105 is moved out of the fixed member 100. Since the entire drawn-out wiring 110 moves greatly, it becomes a resistance when operating the stick 106 and causes the operator to feel uncomfortable.

  In addition, since the wiring 110 of the second variable resistor 105 always moves together with the first rotating member 104, this operation causes deformation such as expansion, contraction, and twisting to be repeatedly applied to the wiring 110 for a long time. There is also a problem that the influence of such operation accumulates due to use, and the wiring 110 may be disconnected.

  Therefore, the present invention has a problem of resistance during stick operation (problem of discomfort in operation) due to the fact that the entire wiring 110 of the second variable resistor 105 always moves as the first rotating member 104 rotates, The purpose is to solve the problem of wiring disconnection.

1. Basic structure of the stick lever unit of this example (Fig. 1)
The basic structure of the stick lever unit of this example will be described with reference to the schematic diagram of FIG.
The stick lever unit 1 (stick lever device) of this example includes a fixing member 2 fixed to the housing of the radio control transmitter as a main body. The fixing member 2 is a member having a substantially rectangular frame shape as a whole having a space in which the rotation mechanism of the stick 3 can be incorporated, and a first variable resistor 4 is provided outside the side wall. The first variable resistor 4 is a rotary variable resistor including a rotating body 6 having a through hole 5 as a rotation operation unit for changing a resistance value, and the shaft is connected to the rotating body 6 through the through hole 5. And the resistance value can be changed by rotating the shaft. An opening 7 is provided on one side wall of the fixing member 2, and the first variable resistor 4 is attached to the outside of the fixing member 2 so that the through hole 5 communicates with the opening 7.

  In the space inside the fixing member 2, a first rotating member 8 that controls the rotation of the first variable resistor 4 is provided, and is pivotally supported so as to be rotatable with respect to the fixing member 2. Yes. The first rotating member 8 is a member having a substantially rectangular frame shape as a whole having a space in which the rotating mechanism of the stick 3 can be incorporated, and a pair of side walls facing each other with its axes aligned with each other. Rotating shafts 9 and 10 are provided so as to protrude. One rotating shaft 10 of the first rotating member 8 is rotatably connected to one side wall of the fixing member 2, and the other rotating shaft 9 is inserted through the opening 7 of the fixing member 2. The first variable resistor 4 is inserted into the through hole 5 and connected to the rotating body 6. Therefore, when the first rotating member 8 rotates with respect to the fixed member 2, the rotating body 6 of the first variable resistor 4 rotates and the resistance value changes.

  In this example, the pair of rotating shafts 9 and 10 of the first rotating member 8 are formed integrally with the main body, and the axes coincide with each other with high accuracy. Rotation is smooth and feels good during stick operation. Further, the first rotating member 8 is first rotatably attached to the fixing member 2, and then the first variable resistor 4 is rotated at the end of one rotating shaft 9 protruding outward from the fixing member 2. Since the body 6 can be inserted and the first variable resistor 4 can be assembled by the procedure of fixing the first variable resistor 4 to the outer surface side of the fixing member 2, it is impossible to assemble the first variable resistor 4 and the rotary shafts 9 and 10. In the stick operation, the first rotating member 8 can be smoothly rotated without imposing a burden on the first variable resistor 4, and the shaft of the shaft-type variable resistor is connected to one of the rotating shafts of the rotating member. The life of the first variable resistor 4 can be extended compared to the conventional stick lever unit used as

  The other rotation shaft 9 of the first rotation member 8 is formed with a lead-out hole 13 for guiding a wiring 12 of a second variable resistor 11 to be described later at its center, one end of which is the rotation shaft 9. The other end side is bent 90 ° upward and is opened on the upper surface of the side wall of the first rotating member 8 through the guide hole 22. That is, the inner side and the outer side of the fixing member 2 are in communication with each other via the lead-out hole 13 of the rotating shaft 9.

  A second variable resistor 11 is attached to one outer surface of the pair of wall bodies of the first rotation member 8 parallel to the rotation shafts 9 and 10. The second variable resistor 11 is a rotary variable resistor including a rotating body 6 having a through hole 5 as a rotation operation unit that changes a resistance value, and has the same configuration as the first variable resistor 4. . One end of the shaft 14 is connected to the rotating body 6 through the through hole 5, and the other end is pivotally supported on the wall body of the first rotating member 8. If the shaft 14 is rotated, the resistance value of the second variable resistor 11 can be changed. A second rotating member 15 is fixed to the shaft 14 in the space inside the first rotating member 8. Accordingly, when the second rotating member 15 rotates with respect to the first rotating member 8, the shaft 14 of the second variable resistor 11 rotates and the resistance value changes.

  The stick lever 3 is attached to the second rotating member 15. Accordingly, the operator operates the stick 3 with his / her finger to rotate the first rotating member 8 and the second rotating member 15 in predetermined directions as necessary, and the first variable resistor 4 and the first variable resistor 4 2 The resistance of the variable resistor 11 can be changed.

  In this example, the second variable resistor 11 is a type in which the resistance is changed by rotating the rotating body 6 having the through-hole 5 similarly to the first variable resistor 4. A shaft type provided with a shaft protruding outside the main body as the operation unit may be used. In this case, the shaft of the second variable resistor is provided so as to be rotatable between the pair of wall bodies of the first rotating member 8 parallel to the rotating shafts 9 and 10. The second rotating member 15 is fixed to the shaft in the space inside the first rotating member 8. Therefore, when the second rotating member rotates with respect to the first rotating member, the shaft of the shaft-type second variable resistor rotates to change the resistance value.

  Although not shown in FIG. 1, the first rotating member 8 and the second rotating member 15 are provided with a restoring mechanism to the neutral position. That is, the first rotating member 8 and the second rotating member 15 can rotate in any direction around a predetermined axis, respectively, but the resistances of the first variable resistor 4 and the second variable resistor 11 respectively. When the neutral position is set to a predetermined median value and no external force is applied to the stick 3, the first rotating member 8 and the second rotating member 15 are brought to the neutral position by the biasing means. It is set up.

  The first variable resistor 4 and the second variable resistor 11 of this example include three electrical wirings (hereinafter also simply referred to as wirings) for a plus signal, a minus signal, and an intermediate tap signal. Although the first variable resistor 4 is fixed to the fixing member 2, the second variable resistor 11 rotates together with the first rotating member 8, so that the wiring of the second variable resistor 11 is temporarily fixed as it is to the fixing member 2. If the structure is connected to a substrate or the like not shown in the drawing, the wiring also operates, and the operation of the wiring affects the feeling of operating the stick 3.

However, in this example, the wiring 12 of the second variable resistor 11 passes from the guide hole 22 of the first rotating member 8 through the outlet hole 13 and is led out of the fixed member 2 from the shaft end of the rotating shaft 9. Yes. That is, since the wiring 12 of the second variable resistor 11 is held in the lead-out hole 13 formed along the center of the rotation shaft 9 of the first rotation member 8, the entire wiring 12 is the first. It does not operate with the rotation of the rotating member 8. For this reason, the presence of the wiring 12 does not give resistance to the rotation of the first rotating member 8, and has no influence on the feeling of operation of the stick 3. Further, since the wiring 12 of the second variable resistor 11 does not move greatly, there is no fear of disconnection due to repeated operations.
In this example, the wiring 12 of the second variable resistor 11 is led out of the fixed member 2 through the lead-out hole 13 formed in the pivot shaft 9 of the first pivot member 8. 2 The wiring 12 of the variable resistor 11 may be led out of the fixing member 2 by forming a lead-out hole in the rotary shaft 10. The lead-out path of the wiring 12 to the outside of the fixing member 2 can be arbitrarily selected according to the convenience of electrical connection with an external device and the necessity in device design.

2. Specific structure example of the stick lever unit 1 ′ of this example (FIGS. 2 to 11)
A specific structural example of the stick lever unit 1 ′ of this example will be described with reference to FIGS. Components that are functionally common to those in FIG. 1 are denoted by the same reference numerals as those in FIG. Each description is accompanied by at least a part of a drawing number to be referred to as necessary.
The stick lever unit 1 ′ of the present example includes a fixing member 2 fixed to the housing of the radio control transmitter as a main body. As shown in FIG. 2 etc., there is a decorative plate 20 fixed on the surface of the housing of the radio control transmitter on the upper surface of the main body, and a side wall 21 is provided below the decorative plate 20 as shown in FIG. Thus, a storage space for the drive mechanism of the stick 3 is defined. This storage space is open downward.

  As shown in FIGS. 2 and 4, the first variable resistor 4 is provided outside a part of the side wall 21 of the fixing member 2.

As shown in FIGS. 8 and 9, an opening 7 is provided on one side wall 21 of the fixing member 2, and the first variable resistor 4 is fixed so that the through hole 5 communicates with the opening 7. It is attached to the outside of the member 2.

  As shown in FIG. 7 to FIG. 9 and the like, a space inside the fixed member 2 is provided with a first rotation member 8 that controls the rotation of the first variable resistor 4. It is pivotally supported so as to be rotatable. The first rotating member 8 is a member having a substantially rectangular frame shape as a whole having a space in which the rotating mechanism of the stick 3 can be incorporated, and a pair of side walls facing each other with its axes aligned with each other. Rotating shafts 9 and 10 are provided so as to protrude. One rotating shaft 10 of the first rotating member 8 is rotatably connected to one side wall 21 of the fixing member 2, and the other rotating shaft 9 is inserted through the opening 7 of the fixing member 2. The first variable resistor 4 is inserted into the through hole 5 and connected to the rotating body 6. Therefore, when the first rotating member 8 rotates with respect to the fixed member 2, the rotating body 6 of the first variable resistor 4 rotates and the resistance value changes.

  In this example, the pair of rotating shafts 9 and 10 of the first rotating member 8 are formed integrally with the main body, and the axes coincide with each other with high accuracy. Rotation is smooth and feels good during stick operation. Further, the first rotating member 8 is first rotatably attached to the fixing member 2, and then the first variable resistor 4 is rotated at the end of one rotating shaft 9 protruding outward from the fixing member 2. Since it can be assembled by inserting the body 6 and fixing the first variable resistor 4 to the outer surface side of the fixing member 2, there is no difficulty in assembling the first variable resistor 4 and the rotating shaft 9, During the stick operation, the first rotating member 8 can be smoothly rotated without imposing a burden on the first variable resistor 4, and the shaft of the shaft type variable resistor is used as one of the rotating shafts of the rotating member. Compared to the conventional stick lever unit, the life of the first variable resistor 4 can be extended.

As shown in FIGS. 7 to 9, the other rotation shaft 9 of the first rotation member 8 is formed with a lead-out hole 13 for guiding the wiring 12 of the second variable resistor 11 described later at the center thereof. One end thereof opens to the end surface of the rotation shaft 9, and the other end side (the main body side of the first rotation member 8) is a guide hole 22 that increases in diameter toward the upper outlet. An opening is formed on the upper surface of the main body of the member 8. That is, the opening diameter of the guide hole 22 is reduced toward the outlet hole 13.

  A second variable resistor 11 is attached to one outer surface of the pair of wall bodies of the first rotation member 8 parallel to the rotation shafts 9 and 10, as shown in FIG. Although not shown in detail in FIG. 7, the second variable resistor 11 is a rotary variable resistor including a rotating body 6 having a through hole 5 as a rotation operation unit that changes a resistance value. 1 is the same configuration as the variable resistor 4. One end of the shaft 14 is pivotally supported on one of a pair of wall bodies of the first rotation member 8 parallel to the rotation shafts 9 and 10, and the other end of the shaft 14 is connected to the other of the wall bodies. It penetrates and is connected to the rotating body 6 of the second variable resistor 11. As shown in FIGS. 7 and 9, a substantially semi-disc-shaped (kamaboko-shaped) second rotating member 15 is positioned in the space inside the first rotating member 8 with the circumferential surface facing upward. It is fixedly provided on the shaft 14. The stick 3 is attached to the center of the peripheral surface (upper surface side center) of the second rotating member 15, and the stick 3 is inserted through the slit of the decorative plate 20 on the upper surface of the fixing member 2 and above the decorative plate 20. It sticks out.

  Therefore, when the second rotating member 15 is rotated with respect to the first rotating member 8 by a stick operation, the shaft 14 rotates and the resistance value of the second variable resistor 11 changes. Further, the operator can arbitrarily operate the stick 3 with two fingers in two orthogonal directions and rotate the first rotating member 8 and the second rotating member 15 in predetermined directions as necessary. The resistances of the first variable resistor 4 and the second variable resistor 11 can be changed by a necessary amount.

  In this example, the second variable resistor 11 is a type in which the resistance is changed by rotating the rotating body 6 having the through-hole 5 similarly to the first variable resistor 4. A shaft type provided with a shaft protruding outside the main body as the operation unit may be used. In this case, the shaft of the second variable resistor is provided so as to be rotatable between the pair of wall bodies of the first rotating member 8 parallel to the rotating shafts 9 and 10. In the space inside the rotating member 8, the second rotating member 15 is attached to the shaft.

  The stick lever unit 1 ′ of this example includes a restoring mechanism that restores the first rotating member 8 and the second rotating member 15 to the neutral position. That is, as described above, the first rotating member 8 and the second rotating member 15 can rotate in any direction around a predetermined axis, respectively, but the first variable resistor 4 and the second variable resistor, respectively. When the neutral position is set so that the resistance of 11 becomes a predetermined median value and no external force is applied to the stick 3, the first rotating member 8 and the second rotating member 15 are moved by the urging means. The neutral position is set.

  As shown in FIG. 11, in the inner space of the fixed member 2, in the vicinity of the side wall 21 on which the other rotation shaft 9 of the first rotation member 8 is provided, the neutral position of the first rotation member 8. An urging plate 23 is provided as a restoring mechanism. The urging plate 23 is a substantially trapezoidal plate body having a plate surface orthogonal to the rotation shafts 9 and 10 and capable of swinging in a plane orthogonal to the rotation shafts 9 and 10. The urging plate 23 is rotatably connected to the fixing member 2 at one end portion thereof, and the other end portion is pulled upward by a spring 24 as urging means provided between the urging plate 23 and the fixing member 2. The edge contacts the pin 25 provided on the first rotating member 8 to set the first rotating member 8 to the neutral position.

  As shown in FIG. 10, an urging plate 26 is provided in the internal space of the first rotating member 8 as a restoring mechanism to the neutral position of the second rotating member 15. The biasing plate 26 is a substantially trapezoidal plate body that has a plate surface orthogonal to the shaft 14 of the second variable resistor 11 and is swingable within a surface orthogonal to the shaft 14. The urging plate 26 is rotatably connected to the fixing member 2 at one end thereof, and the other end is pulled upward by a spring 27 as an urging means provided between the urging plate 2 and the fixing member 2. The edge contacts the pin 28 provided on the second rotating member 15, and the second rotating member 15 is set to the neutral position.

  As shown in FIGS. 4, 5, and 7 to 9, in this example, the wiring 12 of the second variable resistor 11 is drawn out of the fixed member 2 with a special structure. That is, as shown in FIG. 5, the three terminals 30 of the second variable resistor 11 are connected to the three wirings 12 from the three connection terminals 32 via a printed wiring (not shown) provided on the substrate 31. Yes. As shown in FIGS. 7 to 9, these wirings 12 are routed along the outer shape of the first rotating member 8, and are connected to the rotating shaft 9 from the guide hole 22 opened on the upper surface of the first rotating member 8. Is inserted into the lead-out hole 13 and led out of the fixed member 2 through the opening at the end of the rotating shaft 9. As shown in FIG. 4, the wiring 12 led out of the fixing member 2 is connected to the terminal 34 of the substrate 33. Three terminals of the first variable resistor 4 are connected to the board 33, and a total of six wirings of two variable resistors 4 and 11 are connected via a printed wiring (not shown) (plus signal line, minus signal). Signal lines and two intermediate tap signal lines) and connected to the collective terminal portion 35 of the substrate 33.

  Although the first variable resistor 4 is fixed to the fixing member 2, the second variable resistor 11 rotates together with the first rotating member 8, so that the wiring of the second variable resistor 11 is temporarily fixed as it is to the fixing member 2. If the conventional structure of connecting to the substrate 33 and the like is taken out of the wiring, the wiring 12 also operates, and the operation of the wiring 12 affects the feeling of operating the stick 3.

However, according to the present example, as described above, the wiring 12 of the second variable resistor 11 passes from the lead-out hole 13 of the first rotating member 8 through the opening of the shaft end of the rotating shaft 9 and the outside of the fixing member 2. Has led to. Thus, since the wiring 12 of the second variable resistor 11 is held in the lead-out hole 13 formed along the center of the rotation shaft 9 of the first rotation member 8, the entire wiring 12 is provided. Does not operate along with the rotation of the first rotation member 8. For this reason, the presence of the wiring 12 does not give resistance to the rotation of the first rotating member 8, and has no influence on the feeling of operation of the stick 3. Further, since the wiring 12 of the second variable resistor 11 does not move greatly, there is no fear of disconnection due to repeated operations.
In this example, the wiring 12 of the second variable resistor 11 is led out of the fixed member 2 through the lead-out hole 13 formed in the pivot shaft 9 of the first pivot member 8. 2 The wiring 12 of the variable resistor 11 may be led out of the fixing member 2 by forming a lead-out hole in the rotary shaft 10. The lead-out path of the wiring 12 to the outside of the fixing member 2 can be arbitrarily selected according to the convenience of electrical connection with an external device and the necessity in device design.
