Description

[Detailed Description of the Invention] [Industrial Application Field] In this invention, when pulling out the shaft, the knob of the shaft is rotated to one side by a predetermined angle to raise the ring pool, and the ring pool is hooked with a finger or the like. The present invention relates to a shaft forward/reverse rotation, forward/backward movement, and rotation angle control device in which, when the shaft is pushed in, the shaft knob is reversely rotated to the other side by a predetermined angle to collapse the ring pool and return it to its original position.

[Prior Art] Conventionally, when controlling the forward and reverse rotational movement, forward and backward rotation, and rotation angle of a shaft, the knob attached to the shaft is gripped and reciprocated back and forth as it is.
In addition, the shaft is often rotated by rotating a predetermined angle knob. In this case, there are drawbacks such as the hand grasping the outer circumferential surface of the knob slipping, making it impossible to pull out the shaft sufficiently or obtaining an accurate rotation angle.

[Problems to be solved by the invention] When the shaft is moved forward, the shaft is moved forward by grasping the knob fixed to the shaft, and when the shaft is moved backward, the knob fixed to the shaft or at a predetermined angle is The purpose is to rotate a ring pool with an eccentric attachment handhold part attached to the knob, and to expose the handhold part to the front so that the shaft can be pulled out by inserting the tip of a finger, etc. It is something.

[Means for Solving the Problems] The present invention includes a shaft 5 attached to the frame 8 so as to be able to move forward and backward and rotate, and a recess 4 attached to the shaft 5 and housing the ring pool 1.
A handle 2 has a ring pool 1 with a hand grip 7 mounted on a pin shaft 3 supported on the side wall of the handle 2, a stopper 15 attached to a frame 8, and the rotation angle of the shaft 5 is controlled by the stopper 15. Stopper collar 11 attached to shaft 5 so that
and a flange 12 which has a protrusion 16 that engages with an inclined groove 17 provided on the side wall of the link pool 1 and is attached to move forward and backward together with the shaft 5,
Rotate the handle 2 in one direction to disengage the slanted groove 17 of the ring pool 1 and the protrusion 16, open the ring pool 1, hook your finger on the handle 7 of the ring pool 1, and move the pull shaft 5 forward. This is a device for controlling the forward and backward rotation of the shaft as well as the rotation angle.

[Operation] The present invention rotates the handle 2 in one direction to make the stopper 15 abut one side of the stopper collar 11, and engages the protrusion 16 of the flange 12 with the inclined groove 17 of the ring pool 1, thereby removing the ring pool. 1 is housed in the handle 2, the handle 2 is rotated in the other direction, the other side of the stopper collar 11 is brought into contact with the stopper 15, the protrusion 16 of the flange 12 is separated from the inclined groove 17 of the ring pool 1, and the ring is removed. pool 1
is exposed from the handle 2 so that the shaft can be pulled out by placing one's fingers or the like on the handhold part 7 of the ring pool 1.

[Example] 1 is a ring pool, and 2 is a handle in which the ring pool 1 is pivoted with a pin 3. The pin 3 of the ring pool 1 is positioned below the center line 6 of the shaft 5 within the recess 4 provided in front of the handle 2, as shown in FIG. In this position, it always rotates forward under a single load and is opened and exposed in front of the handle 2. Reference numeral 7 denotes a handle portion of the ring pool 1, and the ring pool 1 is rotated around the pin 3 so as to be convenient for pulling out the handle 2 and hence the shaft 5 toward the user at a position where the handle 2 and shaft 5 are pulled out.
The back surface 1a of the ring pool 1 is placed on the inner surface 2a of the handle 2 to prevent the ring pool 1 from rotating any further.

The shaft 5 passes through a bearing 9 of the frame 8 and protrudes to the outside, and a cam latch 10 is fixed to this protrusion, and a stopper collar 11 is fitted and fixed in front of the cam latch 10. Further, in front of the stopper collar 11, a flange 12 is attached to the shaft 5 by a ring 12a, and an L-shaped engagement piece 13 is connected to the flange 12. The stopper 14 is fitted into and locked with a locking portion 15 of a stopper 14 fixed to the stopper 14 to prevent rotation. The handle 2 is provided with an idle groove 2a for the engagement piece 13.

Further, the upper surface of the stopper 14 is formed into a horizontal surface 14a, and the side surface 11a of the stopper collar 11 and the 1
1b is configured with an angle of 90°, and this
One side 11a and the other side 11b having an angle of 90° alternately contact and stop the horizontal surface 14a of the stopper 14 during the reciprocating rotation of the shaft 5, so that the shaft is accurately reciprocated by 90°. Also,
The outer peripheral surface 12b of the flange 12 is formed in a circular shape around the central axis 6 of the shaft 5, and the inner surface 1a of the ring pool 1 rotates in contact with the outer peripheral surface 12b of the flange 12. 16
is a protrusion protruding from a part of the outer circumferential surface 12b of the flange 12, and this protrusion engages with or disengages from the inclined groove 17 provided on the inner circumferential surface of one side of the ring pool 1, thereby making the ring pool 1 In the closed state, the protrusions 16 are engaged with the inclined grooves 17 to maintain the closed state of the ring pool, and in the open state of the ring pool 1, the protrusions 1
The inclined groove 17 is spaced apart from the ring pool 6, and the ring pool is rotated in the opening direction about the pin 3 by the action of its deviated center of gravity. Therefore, the shaft 5 can be pulled out in the forward direction by hooking the finger on the handhold portion 7 of the ring pool 1.

Instead of forming the inclined groove 17 on the inner peripheral surface of one side of the ring pool 1, the inclined groove 17 can also be provided on the inner peripheral surface of both sides of the ring pool 1. In this case, the protrusion 16 will also be provided on the opposite side from the case shown.

Description of Operation Rotate the handle 2 counterclockwise around the shaft 5 to bring the other side surface 11b of the stopper collar 11 into contact with the horizontal surface 14a of the stopper 14 and stop it (FIGS. 2A and 2B). At this time, the ring pool 1 is housed inside the recess 4 of the handle 2 by rotating counterclockwise around the pin 3, and the protrusion 16 of the flange 12 is provided at an angle with respect to the axis 6 of the shaft of the ring pool 1. It is fitted inside the inclined groove 17.

To pull out the shaft 5, move the handle 2 to the third
As shown in FIG. One side 11a of the collar 11 is brought into contact with the horizontal surface 14a of the stopper 14 and stopped. At the same time, since the center of gravity of the ring pool 1 is on the outside of the pin 3, which is the fulcrum (toward the right side of the pin 3 in FIG. It rotates around the pin 3 from the position indicated by the broken line in Figure 1 to the position indicated by the solid line, and the back surface 1a of the ring pool 1 is connected to the top surface 2a of the handle 2.
This prevents the ring pool 1 from rotating any further. After the head of the ring pool 1 is exposed in front of the handle 2 in this manner, the shaft 5 is pulled out to the right (FIG. 1) by hooking the finger on the hand grip 7 of the ring pool 1.

An operating member is attached to the shaft 5,
After operating the required operating members, the handle 2 and the ring pool 1 may be returned to the positions shown in FIGS. 2A and 2B. That is, after turning the ring pool 1 to return to the position indicated by the broken line in FIG. 1 about the pin 3, the handle 2 is rotated in the directions of the arrows in FIG. 1A and FIG. 2B. During this rotation, the protrusion 16 engages with the inclined groove 17 and gradually moves to the base of the inclined groove 17, and the other side surface 11b of the stopper collar 11 is moved to the stopper 14.
The rotation of the handle 2 is stopped by contacting the horizontal surface 14a of the shaft 5, and the return rotation of the shaft 5 is stopped.

[Effect] As described above, in the present invention, the flange 12 engaged with the stopper 14 of the frame 8 so as to prevent the shaft 5 from moving forward and backward and rotating is fitted into the shaft 5, which is attached to the frame 8 so that it can move forward and backward and rotate. By providing the protrusion 16 and engaging the protrusion 16 with the inclined groove 17 provided in the ring pool 1 which is fixed in the recess 4 of the handle 2 with an eccentric pin 3, the handle 2 can be rotated in one direction. Slanted groove 1 of ring pool 1
The position of the protrusion 16 fitted in the groove 7 is moved from the base of the inclined groove 17 toward the outer open end. When the protrusion 16 comes off from the outer open end of the inclined groove 17, the head of the ring pool 1 will fall outward about the pin 3, so insert your finger into the handhold part 7 of the ring pool 1 without grasping the handle 2. At the same time, when the handle 2 is grabbed and the shaft 5 is pushed back, the back of the ring pool 1 is pushed and rotated around the pin 3 to move the ring pool into the recess 4 of the handle 2. When the handle 2 is stored and rotated in the opposite direction, the protrusion 16 can be fitted into the inclined groove 17, and when the handle 2 is rotated in the forward or reverse direction, the stopper collar 11 can be inserted into the stopper 1.
Since the shaft 5 can be rotated by a predetermined angle by stopping at the shaft 4, it is possible to smoothly and reliably operate the actuating member attached to the shaft.
