Description

[Detailed description of the invention] Industrial application field This invention is a swimming technique in which half the body floats on the surface of the water, and while moving forward by rotating both arms alternately, the crawl stroke and backstroke stroke are alternately repeated during the movement. Regarding animal toys.

Conventional technology Conventional swimming toys, such as animal toys that move by rotating their arms alternately to move through the water, are, for example,
A device described in Publication No. 18073 is known.
These swimming toys have been proposed that, in addition to rotating their arms alternately underwater, have elaborate and interesting movements.

Problems to be Solved by the Invention This invention is similar to known swimming toys in that the toy body alternately rotates both arms, but each time the toy moves forward a certain distance, the body, ie neck, remains in the air. The torso, which is integral with the body, is automatically turned over 180 degrees, alternating between lying on one's back and lying down, and by rotating the body, the body repeatedly performs a crawl stroke and a backstroke stroke. Let's move on,
The purpose of this invention is to provide a novel swimming toy that is different from the operation of conventional swimming toys and that gives children and others the experience of swimming.

Means for Solving the Problem Spread the tips of both legs on the same plane to the required length on both sides, make the inside a sealed hollow that communicates with the crotch, mold it as one body, and attach it to the center front of the crotch. A protruding shaft is provided, and the tip of the protruding shaft is fitted into a bearing hole provided at the tail end of a torso shaped like an appropriate animal to connect the torso to the crotch freely. The tip is connected to the shaft of a gear that is supported on a support piece in the body, and this gear is driven by a prime mover installed in the body and has a toothless part at a predetermined position. Both ends of the rotating shaft that rotates in conjunction with the prime mover are projected at predetermined locations on both sides of the body, and the left and right webbed arms are fixed to the shaft ends by displacing the left and right web arms by 180 degrees, and the base ends are fixed to the ends of the shaft. A swimming animal toy is characterized in that a float is mounted in a cavity with a float biased toward the face.

Function The present invention is constructed as described above, with a float enclosed in the neck part 2, and both legs 13 having their tips expanded to the required length on both sides on the same plane, and communicating with the crotch part 14 with the inside sealed hollow. Since it floats on the water surface without sinking, when the prime mover is started, both arms 7, 7
are rotated alternately by the rotation of the rotating shaft 6, and move forward by scraping water. This intermittent toothed wheel 10 also rotates and attempts to rotate the gear 11 that meshes with the intermittent toothed wheel 10, but it is connected to both legs 13, and these two legs 13 are on the same plane with their respective tips on both sides as described above. Since it is expanded to the required length and has a sealed hollow interior that communicates with the crotch part 14, both legs float stably on the water surface, and a large buoyancy moment acts at the center and creates a large resistance to rotation, causing the prime mover to The interior body 1 rotates and changes from a supine state to a prone state by half a turn, and then the rotation of the body 1 continues while the position of the toothless part 9 of the toothless ring passes through the meshing position with the gear 11. The movement will stop, so
The toy body moves forward by rotating both arms while maintaining the previous rotating position, and when the toothed part of the toothless ring comes to the meshing part with the gear 11 again, the body 1 rotates 180 degrees again and moves forward as before. It changes direction to the opposite direction from the body of time and continues to advance. When the body is in this orientation, that is, when it is on its back, it moves like a backstroke, and when it changes to a prone position, it moves like a crawl stroke.
Furthermore, because the float is attached to the side of the swimmer, backstroke is more stable than crawl stroke.

Embodiment The present invention will be explained by an embodiment shown in the drawings.
1 is a hollow body formed in the shape of a suitable animal, and is integrally molded with a neck 2, and a mainspring motor 3 and a machine frame 4 equipped with a deceleration transmission mechanism are attached to the inside of the body. There is. Reference numeral 5 denotes a winding key for a mainspring motor, and reference numeral 6 designates a rotating shaft with outer ends protruding from both shoulders of the body 1, which is connected to the motor 3 and has left and right web arms 7 disposed at the outer ends by 180 degrees. The proximal end is fixed. Reference numeral 8 designates the driving shaft of the prime mover 3, and a toothless wheel 10 having toothless portions 9, 9 provided at symmetrical positions on both sides is attached to the shaft end protruding toward the rear side of the machine frame 4. Reference numeral 11 denotes a gear pivotally supported by a support piece 12 provided in the body, which meshes with the partially toothed ring 10. Reference numeral 13 denotes both legs, which are integrally molded on the same plane with their respective tips expanded to a required length on both sides, with the inside sealed hollow and communicating with the crotch part 14. A protruding shaft 15 is protruded from the center front part of the crotch part 14, and this protruding shaft is inserted into the body through a bearing hole 16 provided at the tail end of the body 1, and the shaft 17 of the gear 11 is connected to the tip. There is. Reference numeral 18 denotes a float mounted on the inside of the hollow neck and biased toward the face side.

Although the above description has been given as an example in which a spring-loaded prime mover is used, the prime mover is not necessarily a spring-loaded prime mover, and of course, a motor may be used as the prime mover.

Effects In this plan, the torso 1 rotates 180 degrees intermittently around the two rear legs that float stably, the whole body is propelled by the rotating arms in the front, and the body alternates between crawl stroke and backstroke. Unlike conventional swimming toys, it has the effect of giving you a special feeling of movement as it moves repeatedly. In addition, a float 18 is built into the neck, which stabilizes floating on the water surface.In particular, since it is attached to the side of the face, backstroke is more stable than crawling, and the rotation of the torso and swimming are more stable. It is characterized by easy and stable levitation and activation.
