Abstract

PURPOSE:To return an inner tube to the preset waiting position when a preceding grip passes an outer tube by providing an energizing member energizing the inner tube so as to rotate the inner tube rotated in the outer tube to the preset waiting position when the grip passes. CONSTITUTION:As the arm of a grip 22 is moved, an inner tube 26 is rotated in an outer tube 32, and the position of a hole generated when slits 28, 34 are overlapped is moved from one end of a double cylinder 24 to the other end. Since the curved slit 28 starting at one end and ending at the same position on the circumference of the other end is provided on the inner tube 26, when the arm of the grip 22 of a carrier 20 passes through the double cylinder 24, the inner tube 26 is rotated in the outer tube 32 against the elastic force of a spring 42, when the arm of the grip 22 has passed, the inner tube 26 is energized by the elastic force of the spring 42, the boss 30 of the rotated inner tube 26 and a recessed groove 40 are coupled, and the inner tube 26 is returned to the original waiting position again. The arm of the grip 22 of the next carrier 20 can thus enter the double cylinder 24.

32 is an outer cylinder on the outside of the double cylinder, and FIG. 3 shows (a) a front view and (b) a side view. The outer cylinder 32 is provided with one linear horizontal slit 34 having a width that allows the arm of the grip 22 to pass through in the longitudinal direction of the outer cylinder 32. In addition, the ends of both the slits 28.34 of the inner tube 26 and the outer tube 32 widen in a tapered shape so that the arm of the grip 22 of the carrier 20 attached to the cable 16 can easily enter the slits 28.34. It has become. Thus, the outer cylinder 32 is fixed to the two-wheel beam 10 via the support plate 36, and the inner cylinder 26 can rotate within the outer cylinder 32.

When the arm of the grip 22 rotates against zero bullet force and the arm of the grip 22 finishes passing through, the inner cylinder 26 is biased by the elastic force of the spring 42, and the boss 30 of the rotated inner cylinder 26... and concave groove 40
is latched and returns to its original standby position. This is done so that the end of the slit 28 of the inner cylinder 26 overlaps the entry end of the slit 34 of the outer cylinder 32 after the carrier 20 has passed through the inside of the double cylinder 24. This is to allow the arm of the grip 22 of the carrier 20 to enter.

Next, another embodiment will be described with reference to FIG.

In the previous embodiment, a spring was used as the biasing member for the inner cylinder, but in this embodiment, a weight is used.

Reference numeral 50 denotes a weight, which is connected to the outer wall of the inner cylinder 54 via a connecting body 52.

The connecting body 52 is capable of swinging in the direction of arrow A within a slot 58 formed in the outer peripheral surface of the outer cylinder 56 in a direction perpendicular to the longitudinal direction of the outer cylinder 56. In this operation, when the arm 60 of the grip passes through the double cylinder 62, the inner cylinder 54 rotates in the same manner as in the previous embodiment.

When the arm 60 finishes passing through, the inner cylinder 54 becomes free, and the weight 50 returns to the vertical direction due to the gravity acting on the weight 50, and returns to a predetermined position due to the engagement of the connecting body 52 and the slot 58. At this time, the ends of both the slits 64 and 66 of the outer cylinder 56 and the inner cylinder 54 are designed to collapse.
