The upper half body 2 and the lower half body 3 are connected by a shaft 9 which is loosely fitted in an insertion hole 2b formed in the partition wall 2a in the vertical direction.

The shaft 9 is prevented from coming off by a washer 11 attached by a screw 10 screwed to the upper end, and when the lower half 3 and the upper half 2 connected to the lower end are connected, Trigger mechanism mounting part 8 from partition wall 2a
It has a length such that when it is protruded by a predetermined amount and the upper half body 2 and the lower half body 3 are separated, an opening portion 12 is formed between the two half bodies 2 and 3 at a predetermined interval.

Further, the shaft 9 is provided between the lower surface of the partition wall 2a and the flange 9a provided on the shaft 9 so that both halves 2, 3 are formed.
Is wound around the first coil spring 13, and the rotor 6 is rotatably provided below the flange 8a.

The rotor 6 has two disks 6a, 6b connected by a partition wall 6c provided radially, and has a shot storage portion 6d with an open outer periphery. The disk 6a has an upper half 2 and a lower half on the upper surface thereof. The rotor 6 that abuts the rib 2c of the upper half 2 when the half 3 is joined
A protrusion 6e serving as a rotation stopper is provided, and a ratchet 6f that engages with the wrapping spring 14 is formed on the lower surface of the disk 6b.

A winding member 15 that applies a winding force to a winding spring 14 is externally fitted to the lower half 3 side of the shaft 9, and a second coil is provided between the winding member 15 and the lower surface of the rotor 6. A spring 16 is provided, and further, the winding spring 14 is wound around the outer periphery of the winding member 15, and one end of the winding spring is engaged with a ratchet 15a formed on the winding member 15. There is.

Further, the lower half of the winding member 15 is provided on the lower surface of the winding member 15 so that when the winding spring 15 is rotated and a winding force is applied to the rotation of the winding member 15, the winding member 15 is not reversed by the winding force. Ratchet 15b engaging with inner bottom surface of 3
And a wrapping member 15 provided outside the bottom of the lower half 3
A ratchet 15c that engages with a knob 17 that rotates is formed.

The knob 17 has a shaft portion 17a in the bottom insertion hole 3a of the lower half body 3.
And is attached to the lower end of the shaft 9 together with the wrapping member 15 by means of a screw 18, whereby the lower half 3
Is also connected to the lower end of the shaft 9.

Further, the trigger mechanism 7 includes an upper half body 2 and a lower half body 3.
When the upper half body 2 and the lower half body 3 are joined to close the opening 12 by a casing 19 attached to the trigger mechanism attachment portion 8 of the upper half body 2, the trigger is generated. A hook lever 20 as a holding member that locks the washer 11 attached to the upper end of the shaft 9 protruding into the mechanism attachment portion 8 to hold the coupled state, and the hook lever 20 operates to release the coupled state. The first on the shaft 9
A cam plate 21 for separating the halves 2 and 3 by the biasing force of the coil spring 13, a mainspring drive mechanism 22 for rotating the cam plate 21, and a stopper as a locking member for restricting the drive of the mainspring drive mechanism 22. The lever 23 and the stopper lever 23
And a locking pin 24 for locking in a restricted state.

The hook lever 20 is an L-shaped lever that is rotatably provided on the casing 19. The hook 20b of the locking arm 20a locks the washer 11, and the spring 25 provided between the casing 19 and the working arm 20c. Thus, the locking arm 20a is always biased in the locking direction, and the locking arm 20a is moved in the releasing direction by the cam projection 21a of the cam plate 21 that pushes the working arm 20c.

The cam plate 21 is axially supported by the casing 19 and the mainspring drive mechanism 22, and is rotated in both forward and reverse directions by the mainspring drive mechanism 22, and one of its shaft portions is exposed on the side surface of the casing 19 as a rotation amount display scale 21b. There is.

The mainspring drive mechanism 22 includes a mainspring 22b that is wound up by a knob 22a, a gear train 22c that reduces the return force of the mainspring 22b and transmits it to the cam plate 21, and the stopper lever 2
3 and a stopper 22d that is pressed by the stopper protrusion 23a to restrict the rotation of the gear train 22c.

The stopper lever 23 is provided so as to be rotatable and detachable by hooking a claw 23a on the shaft 19a of the casing 19, and the stopper protrusion 23b is locked to the casing 19 by a locking pin 24 so that the stopper protrusion 23b is a stopper of the mainspring drive mechanism 22. 22d is pressed to regulate the drive of the mainspring drive mechanism 22, and the engagement between the stopper projection 24b and the stopper 22d of the mainspring drive mechanism 22 is released by removing the locking pin 24 and rotating or removing the stopper lever 23. Then, the mainspring drive mechanism 22 is rotationally driven.

Next, the operation of the grenade toy 1 configured as described above will be described. With the stopper lever 23 and the locking pin 24 attached to the casing 19, the shot storage portion of the rotor 6 through the opening 12 of the bullet 4 is described. 6d contains an appropriate amount of shots 5 and the upper half 2
And the lower half 3 to close the opening 12 and rotate the knob 22a of the mainspring drive mechanism 22 to wind the mainspring 22b, the cam projection 21a of the cam plate 21 reverses and the working arm 20c of the hook lever 20 moves. The hook portion 20b of the hook lever 20 is locked to the washer 11 at the upper end of the shaft 9 protruding from the trigger mechanism mounting portion 8 of the upper half body 2 so that the upper half body 2 and the lower half body 3 are connected to each other. Held in.

In this state, when the knob 17 at the bottom of the lower half 3 is rotated, the wrapping spring 14 is engaged with the ratchet 15a of the wrapping member 15 and the ratchet 6f of the rotor 6, and the protrusion 6e on the upper surface of the rotor 6 Since the rib 6 is engaged with the rib 2c of the upper half body 2, the rotor 6 does not rotate and the winding force is accumulated on the winding spring 14.

Then, when the locking pin 24 is removed and the stopper lever 23 is rotated or removed from the casing 19, the cam plate 21 starts to rotate due to the returning force of the mainspring 22b, and the cam projection 21a pushes the working arm 20c of the hook lever 20. The hook portion 20b of the hook lever 20 and the washer 11 at the upper end of the shaft 9 are unlocked, and the upper half body 2 and the lower half body 3 become the first coil spring.
The opening 12 is formed between the two halves 2 and 3 by being separated by the biasing force of 13.

At this time, the rotor 6 has a protrusion 6e on its upper surface and the upper half 2
Contact with the rib 2c is eliminated, and the second coil spring 16 arranged at the lower portion causes the shot storage portion 6d to open.
The rotor 13 is rotated by the winding force accumulated in the winding spring 14, and the shots 5 are repelled by the centrifugal force and the partition wall 6c due to this rotation and are ejected from the shot storage 6d to the outside of the shell 4. Is released vigorously.

Therefore, the shot 5 is scattered in the same state as when the grenade exploded.

In addition, since the mainspring drive mechanism 22 starts to drive, the upper half body 2
The time until the lower half 3 is separated from the lower half 3 can be adjusted by the winding amount of the mainspring 22b, and can be confirmed by visually observing the rotation amount display scale 21b of the cam plate 21 exposed on the side surface of the casing 19, and the rotor 13 Is proportional to the winding force accumulated on the winding spring 14.

[Effect of device]

As described above, the grenade toy of the present invention is provided with a rotor for rotatably storing a shot in a hollow ammunition body composed of two halves, and when the two halves are separated from each other, the rotor is stored. Since it is rotated and ejected outside the bullet, the shot is scattered like a grenade explodes.
