Description

DETAILED DESCRIPTION OF THE INVENTION A. Object of the Invention (1) Field of Industrial Application The present invention relates to a fish model (pseudo fish) that moves in a manner similar to the movement of an actual fish.

This can be used, for example, as a toy, as an ornament, or as a lure.

(2) Prior art and its problems Conventionally, there have been many fish models, some of which are movable. However, these move simply by the rotational movement of a screw, spatula, etc., and do not resemble the movements of actual fish at all. Therefore, their effectiveness as ornaments, toys, and lures is extremely low.

B. Structure of the Invention (1) Means for Solving the Problems The simulated fish consists of a motor box, a rocking body, and a fish shape. There is a motor box on the side of the fish-shaped head.
A rocking body is housed on the tail side. The motor box has a battery compartment, a motor connected to the battery terminal, and two pistons connected to the motor via a crank. The rocking body is
The pistons are connected to each other by wires, and when the motor is driven, the pistons move in opposite directions.
This movement is transmitted to the oscillating body by the wire, and the oscillating body oscillates in a fish-shaped left and right direction centering on its end on the motor box side. As a result, the surrounding fish shape also swings in the left-right direction.

(2) Effect Current flows from the battery compartment to the motor, causing it to rotate. This motion is transmitted via the crank to the two pistons, which move in opposite directions. Each of these movements is transmitted to the oscillating body by a wire, and the oscillating body oscillates in the fish-shaped left and right direction around its end on the motor box side. As a result, the surrounding fish shape also swings in the left-right direction.

(3) Examples In the drawings, the same reference numerals indicate the same or corresponding parts.

It consists of a pseudo fish 1, a motor box 2, an oscillating body 3, and a fish shape 4.

The fish shape 4 has a head 41 and a body 4 made of elastic material such as rubber.
2, the inner diameter changes at the rear end of the head 41, and the outer diameter changes at the front end of the body 42, and when the two are pressed together, they fit into each other (see Figures 2 and 3). ). Reference numeral 43 denotes a motor box storage chamber formed within the head 41 and the body 42, and is connected to a rocking body storage chamber 44 formed in the center of the body 42 through its small diameter portion 43a. Small diameter part 43
The diameter of a is changed so that it can fit into the motor box 2 in a fluid-tight manner. Numeral 91 is a through hole bored in the fish shape 4 (FIG. 2), through which the pseudo fish 1 can be controlled from the outside by threading a thread 92 (FIG. 3). Furthermore, by passing a fishing line with a fishhook instead of the line 92, the artificial fish 1 can be used as an artificial bait.

The motor box 2 includes a battery compartment 21 that is liquid-tightly closed with a lid 98, a motor 22 connected to the battery terminal 21a of the battery compartment, a worm 26 fixed to the shaft of the motor, and a worm 26.
Worm gear 27 that meshes with the worm gear 27
a crank axle 5 fixed at the center of the crank axle 5; and disks 71, 7 whose centers are fixed at both ends of the crank axle 5.
2. It has connecting rods 73, 74 and pistons 24, 25. The pistons 24, 25 and the disks 71, 72 are connected by connecting rods 73, 74, respectively. Pin M and disk 72 connecting disk 71 and connecting rod 73
The pin N connecting the connecting rod 74 and the crank axle 5
Located on opposite parallel lines with respect to.

crank axle 5, discs 71, 72 and pin M,
N constitutes a crank, and of course the discs 71, 7
A normal crank arm may be used instead of 2.

The free ends 6 of the pistons 24 and 25 protrude outside from the partition wall 7, and a projecting wall 8 is formed around the free ends 6. The outer periphery of the protruding wall 8 is changed to match the shape of the small diameter portion 43a, and is fluid-tightly fitted to the small diameter portion 43a. If the outer periphery of the projecting wall 8 is made of an elastic material, the liquid tightness will be further improved.

In the examples shown in FIGS. 3, 9, and 10, the swinging body 3 is connected to blocks 3 which are swingably connected by pins 31 in order.
It consists of a to 3e. The wires 51 and 52 have one end attached to the right part R and the left part L of the most tail block 3e, respectively, and are perforated on the left and right sides so that they do not separate from the middle blocks 3b, 3c, and 3d during rocking. It passes through the slanted through hole G.
The ring 80 is an annular body made of spring steel fixed to the other ends of the wires 51 and 52, and is attached to the through hole T of the free end 6 of the piston. The frontmost block 3a abuts against the motor box 2.

The method for assembling the pseudo-fish 1 is as follows. First of all,
A thread 92 is passed through the through holes 91 in the body part 42 and the head part 41. Next, the ring 80 is pushed out against its elastic force and attached to the through hole T of the piston (19th
figure). When the rocking body 3 and the unit 33 of the motor box 2 thus completed are placed in the storage chambers 44, 43 in the body 42 (FIG. 20), the projecting wall 8 is fitted into the small diameter portion 43a in a liquid-tight manner. Finally, head 41
Cover the motor box 2 and fit it into the body 42 (FIG. 21). In this way, pseudo-fish 1 is completed (Fig. 1).

When the motor 22 is driven, two pistons 24 and 2
5 move in opposite directions, and this movement is transmitted to the oscillator 3 by the wires 51 and 52, and the oscillator oscillates in the left-right direction of the fish-shaped 4 around the block 3a at the end on the motor box 2 side. do. As a result, only the rear half of the surrounding fish-shaped 4 swings in the left-right direction.

13-18 show other embodiments. The projecting wall 8 is annular and has a male thread cut on its outer periphery. bag 1
1 consists of a bag-shaped impermeable membrane 12 and a ring 13 liquid-tightly fixed to the inlet and outlet of the membrane. 14 is O
It's a ring. During assembly, after the swinging body 3 is attached to the motor box 2, the bag 11 is placed over the swinging body 3, and the ring 13 is screwed onto the projecting wall 8. Other assembly methods, configurations, and operations are the same as in the previous example.

FIG. 12 is a front view of another embodiment of the rocking body 3, and FIG. 11 is a plan view thereof. 61 is a compression coil spring having a spring receiver 62 at its end. The right part R (upper part of FIG. 11) and the left part L (first part) of the spring receiver 62
Wires 51 and 52 are attached to the lower part of Figure 1), respectively. The wire is passed through the inside and outside of the spring 61 as appropriate so that it does not separate from the spring 61 during rocking.

C. Effects of the Invention According to the present invention, since only the rear half of the fish shape can be swung left and right, it is possible to provide a pseudo-fish that moves in a manner similar to an actual fish.
