Description

  The present invention relates to a trigger unit of a transmitter (controller) that transmits a control signal to various radio control models such as radio control (radio control) model automobiles, and more specifically, the trigger main shaft of the trigger unit is directed toward the grip unit (front side). It is related with the trigger unit which can move so that a trigger main axis may adjust to movement of a finger, when pulling it in a direction.

  The trigger unit of a conventional radio-controlled model transmitter is often a throttle trigger that has a unit function for speed adjustment (including forward / reverse switching), and pulls the trigger spindle toward the front (grip unit direction). In this way, the speed of the radio controlled model is increased by applying a load, and the speed is reduced by loosening the force pulling the trigger spindle (releasing the load on the trigger spindle).

4A and 4B are front views showing a conventional type trigger unit, in which FIG. 4A shows a state in which no load is applied to the trigger spindle toward the grip unit, and FIG. 4B illustrates a load applied to the trigger spindle toward the grip unit. It is in a state of multiplying.

  That is, the trigger spindle 1 is applied to the abdominal surface of the tip of a finger (preferably a right-handed person's left index finger) and force is applied to the abdominal surface (with a load applied). When the trigger spindle 1 is pulled toward the front side, the trigger spindle 1 is rotated around the root shaft portion 4, and the tip 2 of the trigger spindle 1 is drawn toward the grip unit B, and is provided near the base end 3 of the trigger spindle 1. The core convex portion 5 pushes up the swing lever 6, and as a result, the vertical spring 7 connected to one end of the swing lever 6 is extended.

Next, when the load applied to the trigger main shaft 1 is released, the swing lever 6 and the eccentric convex portion 5 are returned to their original positions by the pulling force of the vertical spring 7, and the trigger main shaft 1 is also centered on the root shaft portion 4. It is rotated back to its original position.
As described above, the trigger spindle 1 moves linearly, such as approaching or moving away from the grip unit 2 by applying or releasing a load to the trigger spindle 1 with the root shaft portion 4 as the center. there were.

  In the conventional trigger unit described above, the trigger main shaft 1 moves linearly in the direction of the arrow in FIG. 4A around the root shaft portion 4, and as a result, the trigger main shaft 1 only moves in the linear direction. there were.

However, when the trigger spindle 1 is moved in the linear direction, it is necessary to bend each joint of the finger on the trigger spindle 1 more than necessary, which is unnatural when viewed from the movement of the finger. There was a problem of being strong.

  The present invention is well adapted to the movement of the finger when pulling the trigger spindle 1 in the direction of the grip unit B so that the trigger spindle 1 can be operated in an easy and natural manner without bending each joint of the finger more than necessary. Therefore, it is intended to provide a radio-controlled model transmitter trigger unit that can solve all the above problems.

An orthogonal shaft extending in a direction substantially perpendicular to the orthogonal shaft is provided, a rotation support shaft is provided near the tip of the orthogonal shaft, an eccentric protrusion is provided at a position adjacent to the rotation support shaft at the end of the orthogonal shaft, and the trigger main shaft is gripped. When a load is applied in the unit direction, a swing lever that is pressed by this eccentric protrusion is provided. One end of this swing lever is attached to the transmitter body, and the other end of the swing lever. Is a trigger unit for a radio controlled model transmitter, wherein the coil spring is locked to the tip of the coil spring, and the base end of the coil spring is locked to the main body of the transmitter.

  Further, according to a second aspect of the present invention, there is provided a trigger unit for a radio controlled model transmitter according to the first aspect, wherein a pinching portion is formed at a tip of the orthogonal shaft so as to hold the swing lever.

  The trigger unit of the radio controlled model transmitter according to claim 1 is configured such that the trigger spindle is not drawn linearly with respect to the grip unit, but is drawn while drawing an arc, and the trigger spindle 1 is attached to the grip unit B. When pulling in the direction, the trigger operation can be performed in an easy and natural way without bending each joint of the finger on the trigger spindle 1 more than necessary. Exhibits excellent smoothness.

  The trigger unit of the radio-controlled model transmitter according to claim 2 is formed with a sandwiching portion configured to sandwich the swing lever at the tip of the orthogonal shaft, so that the trigger unit has a compact configuration and is an object of the present invention. Demonstrates the excellent effect of reliably achieving the intended purpose of drawing the arc of the trigger spindle to the grip unit while drawing.

It is a front view of the transmitter for radio controlled models provided with the trigger unit of the present invention. In the trigger unit of this invention, it is drawing of the state which has not applied the load to the grip unit direction on the trigger main axis | shaft, (a) is a top view, (b) is a front view. In the trigger unit of this invention, it is drawing of the state which applied the load to the grip unit direction to the trigger main axis | shaft, (a) is a top view, (b) is a front view. In the front view of the conventional trigger unit, (a) is a state in which no load is applied to the trigger main shaft in the direction of the grip unit, and (b) is a state in which a load is applied to the trigger main shaft in the direction of the grip unit.

Hereinafter, an embodiment of a trigger unit A of a radio controlled model transmitter of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a radio-controlled model transmitter provided with the trigger unit A of the present invention. The radio-controlled model transmitter includes a grip unit B, an upper body, in addition to the trigger unit A of the present invention. C, steering unit D, battery unit E, etc. are mounted.
