The present invention relates to a firearm toy whose main purpose is to attach a doll toy to enjoy a pose, and not only to enjoy a static pose as before, but also to enjoy a firing operation. , To provide a firearm toy incorporating a gimmick mechanism.

The firearm toy proposed for this problem has the appearance of a revolver equipped with a rotary magazine as an overall appearance, and the rotary magazine and barrel are movable, and the magazine for the rotation of the rotary magazine and the recoil motion of the barrel. -Bullet tuning mechanism, this magazine-Clutch mechanism that allows the barrel tuning mechanism to be operated manually and automatically, and during automatic operation, the exposed parts exposed to the outside are continuously rotated, while the rotary magazine Includes one or more gimmick mechanism as a rotation tuning mechanism for rotating stepwise at a predetermined angle (60° for 6 consecutive shots).

The gimmick mechanism of the magazine-barrel synchronization operation includes a drive gear that transmits a drive force (for example, by a motor), a magazine shaft shaft that rotates by receiving the drive force from the drive gear, and a cam that is operated by the magazine shaft shaft. A rotary magazine which is provided rotatably around the magazine shaft shaft and has an engaged portion having a plurality of engagement receiving shapes arranged in the circumferential direction on an end surface; and a driving force received from the drive gear. A rotary engagement body that rotates and engages the engagement receiving shape by a predetermined angle during one rotation of itself to rotate the rotary magazine by the angle. The cam has a cylindrical driving joint that rotates together with the magazine shaft, and a driven joint that reciprocates in the axial direction of the barrel according to the cam surface of the driving joint. The barrel operates according to this follower.

More specifically, the drive gear drives a driven gear, the driven gear rotates a shaft drive gear, and the shaft drive gear rotates a shaft driven gear fixed to the magazine shaft shaft. When the magazine shaft shaft rotates in accordance with the shaft driven gear, the driving joint of the cam operates and the barrel connected to the driven joint operates. On the other hand, the rotary engagement member is provided on an end face of the shaft drive gear and rotates together with the shaft drive gear, and the rotary engagement member engages the rotary magazine by the predetermined angle during one rotation. Engage with the receiving shape to rotate the rotary magazine by that angle. The rotary engagement body may be a protrusion integrally formed on an end surface of the shaft drive gear.

The engaged portion in the rotary magazine has a plurality of arcuate concave surfaces having a predetermined radius of curvature arranged in the circumferential direction, and an engaging groove is formed between the arcuate concave surfaces as an engagement receiving shape. can do. The rotary engaging body has a disc portion having a radius corresponding to the radius of curvature of the circular arc concave surface and capable of contacting with the circular arc concave surface, and a rotation formed by cutting out a part of the circular disc portion. The protrusion may be formed in the allowable space. That is, when the disk portion and the circular arc concave surface are in contact with each other while the rotary engagement body rotates, the circular engagement portion functions as a stopper that blocks the rotation of the rotary magazine, and the rotation permitting space faces the circular arc concave surface. When this contact is released, the projecting piece engages with the engaging groove to rotate the rotary magazine. When the rotation advances by a predetermined angle, the projecting piece separates from the engaging groove, and the disk portion comes into contact with the next arc concave surface. As described above, step rotation and rotation stopper for each predetermined angle are realized for the magazine.

Is slidable in one direction and is biased toward the other rotary shaft shaft, and these rotary shaft shafts are engaged by the biasing force at end faces having ratchet shapes corresponding to each other. .. When the driven gear is driven by the drive gear (automatic operation by a motor, etc.), the rotation shaft shaft rotates in a direction in which the ratchet shapes of the end faces mesh with each other, so that the shaft drive gear follows the driven gear. Rotate. On the other hand, when the operation wheel is manually rotated, the shaft drive gear is rotated manually, but at this time, the ratchet shape of the end face is opposite to the meshing direction. Since the rotary shaft of the shaft drive gear rotates, the slidable rotary shaft slides against the biasing force while only the shaft drive gear rotates, and the rotary force is not transmitted to the driven gear. .. Therefore, even if the drive gear is attached to the output shaft of the motor, the drive gear and the driven gear can be operated according to the manual operation without transmitting the rotational force to the drive gear and the driven gear.

Since the operation wheel is a component that is fixed to the magazine shaft shaft and is exposed to the outside, it continuously rotates according to the magazine shaft shaft when it is automatically operated by the drive gear. On the other hand, since the rotary magazine rotates stepwise at a predetermined angle (60° in the case of 6 consecutive firings) according to the action of the engaged portion and the rotary engaging body, the magazine rotates continuously while the wheel rotates continuously. A gimmick mechanism of stepwise rotation tuning is constructed.

With the firearm toy according to the above proposal, it is possible to enjoy the gimmick that the rotary magazine rotates step by step for each shot, and the barrel reacts in response to the step rotation. That is, when combined with a doll toy, it is possible to enjoy not only the static pose but also the shooting action.

The engaged portion 1a has a number of arc concave surfaces 1b having a predetermined radius of curvature arranged in the circumferential direction according to the number of mounted bullets (six in this embodiment). Then, between the arcuate concave surfaces 1b, engagement grooves 1c are formed as engagement receiving shapes.

In the case of the present embodiment, the rotary engagement body 18 for stepwise rotating the rotary magazine 1 in cooperation with the engaged portion 1a is a protrusion integrally formed on the circumferential edge portion of the end face of the shaft drive gear 12. It is provided. Therefore, the rotary engagement body 18 receives a driving force from the drive gear 10 via the driven gear 11 and rotates, and during a single rotation of itself, only a predetermined angle (about 60° because the number of bullets is 6 in this embodiment). It engages with the engaging groove 1c and rotates the rotary magazine 1 by that angle.

The rotary engagement body 18 according to the present embodiment has a disc portion 18a having a radius corresponding to the radius of curvature of the arc concave surface 1b of the engaged portion 1a and capable of contacting the arc concave surface 1b. It is formed as a protrusion in a rotation permitting space 18b formed by cutting out a part of 18a. If the disk portion 18a and the arcuate concave surface 1b are in contact with each other while the rotary engagement body 18 rotates, it functions as a stopper that blocks the rotation of the rotary magazine 1, and when the rotation permitting space 18b faces the arcuate concave surface 1b, The contact between the disk portion 18a and the arcuate concave surface 1b is released, and the rotary engaging body 18 which is a projecting piece engages with the engaging groove 1c to rotate the rotary magazine 1 by one step (60°). When the rotation advances by a predetermined angle (60°), the rotary engagement body 18 separates from the engagement groove 1c and the disc portion 18a abuts on the next arc concave surface 1b.

The firearm toy of this embodiment can be manually operated as well as automatically operated by the motor M. The clutch gimmick mechanism that enables the manual operation and the automatic operation is configured by a clutch shaft 13 provided between the driven gear 11 and the shaft drive gear 12. The clutch shaft 13 includes a rotary shaft shaft 11a of the driven gear 11 and a rotary shaft shaft 12a of the shaft drive gear 12. In the present embodiment, the rotary shaft shaft 12a is provided so as to be slidable in the axial direction. The end faces of the shafts 11a and 12a are pressed against each other by being biased by the coil spring 12b toward the shaft 11a. The end surfaces of the rotary shafts 11a and 12a have ratchet shapes corresponding to each other, and are engaged by the biasing force of the coil spring 12b.

When the driven gear 11 is driven by the drive gear 10 (automatic operation by the motor M), the rotation shaft shafts 11a and 12a rotate in a direction in which the ratchet shapes of the end faces mesh with each other, so that the shaft drive gear 12 follows the driven gear 11. Rotate.

An operation wheel 19 is fixed to the magazine shaft 14 so as to be adjacent to the shaft driven gear 15. The operation wheel 19 is exposed to the outside so that it can be manually operated (see FIG. 1). When the operation wheel 19 is rotated manually, the shaft drive gear 12 is rotated by the manual operation (that is, reverse rotation), and the rotary shaft 12a is rotated in the direction opposite to the direction in which the ratchet shape of the end face meshes. Rotate. Then, while the rotating shaft 12a slides against the biasing force of the coil spring 12b (overcoming the ratchet shape), only the shaft driving gear 12 rotates, and the rotating force is not transmitted to the driven gear 11. Therefore, the rotary magazine 1 can be stepwise rotated and the barrel 2 can be recoiled according to the manual operation of the operation wheel 19 without transmitting the rotational force to the drive gear 10 and the driven gear 11 attached to the output shaft of the motor M. ..

The operation wheel 19 is a component that is fixed to the magazine shaft shaft 14 and rotates together therewith and is exposed to the outside. Therefore, the operation wheel 19 continuously rotates according to the magazine shaft shaft 14 during automatic operation of the drive gear 10. On the other hand, since the rotary magazine 1 rotates stepwise every 60° in accordance with the action of the engaged portion 1a and the rotary engaging body 18, a gimmick mechanism of continuous rotation of the wheel and rotation of the magazine in 60° step is visually pleasing.
