Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a top-turning ejector for rotating and firing a rotary top by utilizing the rotational power of a rubber cord.

[Conventional technology]

Heretofore, there has not been a beating machine launcher similar to the present invention.

[Problems to be solved by the device]

The purpose of the present invention is to rotate and rotate the spinning top in one direction with the spinning top inserted and held at a predetermined position of the launcher body, so that the rubber string for rotation drive can be wound around the rotating bobbin. In addition, by performing a trigger operation in this rubber winding state, an attempt is made to provide a spinning machine ejector configured such that a rotary spinning machine is rotated at high speed by rubber power and can be rotationally fired onto a floor surface. It is a thing.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a tipping pivoting device 3 of the present invention has a handle portion 2 and a tip shaft supporting portion 3 and a tip end shaft supporting portion 3 in which a rubber hook 4 is projected on an outer side portion of the handle portion 1. Piston-type ejector body 1 with rubber string introduction window 5 opened on the circumferential side
And a rubber bobbin 8 having a rubber hook 7 which is rotatably supported by a bobbin rotary shaft 6 in the tip shaft support 3 of the launcher body 1, and a rubber hook of the rotary bobbin 8. 7 and a rubber hook 9 of the launcher main body 1 through a rubber string introduction window 5 for rotation driving rubber string 9, and a square hole 11 into which a square engaging projection 24 of a rotary top 20 is loosely inserted. And a ratchet gear 10 provided at the lower end of the bobbin rotation support shaft 6 so as to rotate integrally with the bobbin 8, and an annular engagement groove of a projection claw 12 and a rotary top 20 that engages and disengages with the ratchet gear 10. A trigger movable body 15 incorporated in the launcher body 1 so as to be reciprocated by a finger pulling operation of a rear end trigger portion 14 having a hook-and-hook engagement projection piece 13 at a tip thereof, And a spring 16 for biasing the gold movable body 15 forward.

[Action]

The top turning ejector having the above-described configuration inserts and engages the engaging protrusion 24 of the rotary top 20 at a predetermined position of the ejector body 1 (the central angle hole 11 of the ratchet gear 10), and the protrusion claw of the trigger movable body 15 is inserted. 2 is used for the ratchet gear 10, and the top engaging projection 13 of the trigger movable body 15 is engaged with the annular engaging groove 23 of the rotary top 20 in a set state as shown in FIG. The rubber string 9 for rotational driving can be wound around the rotary bobbin 8 by manually rotating the rubber cord in one direction (arrow direction in FIG. 3). In addition, when a trigger operation is performed by placing a finger on the trigger portion 14 of the trigger movable body 15 in this comb winding state, engagement of the protrusion claw 12 with the ratchet gear 10 and rotation of the locking protrusion 13 are performed. The engagement with 20 is disengaged, and at the moment of this engagement and disengagement, the ratchet gear 10 and the rotary top loosely inserted in the gear center angle hole 11
20 rotates at high speed by the rubber power of the rubber cord 9, and the rotary top 20 is disengaged from the ratchet gear 10 and is rotationally fired on the floor surface.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. First
Reference numeral 20 shown in FIG. 3 to FIG. 3 includes a rotating shaft made of synthetic resin, which is used in combination with the spinning device of the present invention. The rotating spinning shaft 20 is provided at the center of the upper surface of the spinning frame body 21.
And a ring-shaped engaging groove 23 at the upper end of the spinning shaft 22.
And a square-shaped engaging protrusion 24.

The tipping device of the present invention has a handle portion 2 and a hollow tip shaft supporting portion 3, and a rubber hook 4 is projectingly provided on an outer side portion of the handle portion 1, and a peripheral side portion of the tip shaft supporting portion 3 is provided. The pistol-type launcher main body 1 having a rubber string introduction window 5 is provided. This launcher body 1 includes a lower body molded product 1a and an upper body molded product 1a.
1b is made of synthetic resin and is joined as shown in FIG. 1. The lower main body molded product 1a has two sliding elongated holes 17a,
17b is provided.

A rubber bobbin rotary bobbin 8 having a rubber hook 7 is rotatably supported by a bobbin rotary shaft 6 in the tip shaft support 3 of the launcher body 1, and the rubber hook of the rotary bobbin 8 is supported. A rubber string 9 for driving rotation is hooked on the rubber hook 7 of the gun body 7 and the rubber hook 4 of the gun body 1 through the rubber string introduction window 5. Further, a square engagement projection 11a for propeller rotation is provided on the upper end of the bobbin rotation support shaft 6, and a rotary top 2 is provided on the lower end.
A ratchet gear 10 having a central square hole 11 into which a square engagement protrusion 24 of 0 is loosely inserted is provided so as to rotate integrally with the bobbin 8. The ratchet gear 10 and the bobbin rotary support shaft 6 are integrally formed of synthetic resin, and the bobbin 8 is fitted to the shaft portion of the bobbin rotary support shaft 6 having a D-shaped cross section as shown in FIG. However, the ratchet gear 10
When the bobbin rotary support shaft 6 is formed as a separate component, the central angle hole 11 can be provided at the lower end of the bobbin rotary support shaft 6.

Reference numeral 15 denotes a trigger movable body incorporated in the main body of the ejector 1 so as to be movable back and forth along the sliding long holes 17a and 17b.
Is a ratchet gear 10, a protruding claw 12 that engages and disengages the ratchet gear 10, and a rotating top 20.
The ring-shaped engaging groove 23 has a top-and-bottom locking projection 13 at its tip, which can be moved backward by a finger pulling operation of the rear end trigger portion 14, but when the trigger operation is released, It is returned and moved forward by the urging force of the compression spring 16 built in the projectile body 1. An arcuate concave portion 13a that engages with the annular engaging groove 23 of the rotary top 20 in a disengageable manner is provided at the tip of the top engaging projection 13.

FIG. 4 and FIG. 5 show a propeller attached to the spinning top launcher of the present invention. The propeller 25 has three blades 28 integrally provided between an outer ring 26 and a central boss 27. The central boss portion 27 is provided with a central square hole 29 that is loosely inserted into the square engagement protrusion 11a at the upper end of the bobbin rotation spindle 6. If the propeller 25 having such a structure is provided as a set product, the propeller 25 can be rotationally fired in the air by using the top spinning ejector of the present invention.

[Effect of device]

Since the top spinning ejector of the present invention has the above-described structure, the rotary top 20 is manually rotated in one direction while the rotary top 20 is inserted and held at a predetermined position of the main body 1 of the ejector. By doing so, the rubber string 9 for rotation drive can be wound around the rotary bobbin 8. By operating the trigger in this rubber wound state, the rotary top 20 is rotated at high speed by the rubber power, and the floor top surface is rotated. Therefore, it is possible to inexpensively provide a spinning top ejector having a novel structure that does not exist in the past and has a high degree of interest.
