Description

DETAILED DESCRIPTION OF THE INVENTION The invention in the technical field to which the invention pertains relates to a traveling toy in which wheels are magnetically attracted to the outer surface of a driving body and the wheels are rotated to travel.

Prior Art and Its Disadvantages In conventional traveling toys, wheels are fixed to both ends of an axle that is rotated by a spring drive unit or motor. Therefore, even if the appearance of a traveling toy is changed by replacing the body, the wheels cannot be easily replaced and the wheels do not match the body, which limits the enjoyment of changing the appearance.

Purpose of the Invention In view of the above points, the present invention separates a rotating shaft rotated by a rotational force generating means such as a motor or a spring drive unit from a wheel, and also connects the tip of the rotating shaft and the wheel with an attractive force of a magnet. It is an object of the present invention to provide a traveling toy whose wheels, body, etc. can be replaced at will by connecting them with a t-twist.

Examples of this invention Next, one embodiment of the present invention will be described based on the drawings.

First Example As shown in FIG. 1, the first example is an example in which the present invention is realized to have a simple appearance and form.

In this case, the traveling toy V1 includes a driving body A having a desired external shape, and four wheels B1 to B provided on the front, rear, left, and right sides.
4, and two accessories CI and C2 added as a preferred embodiment.

As shown in FIG. 2, the driving body A basically consists of a housing A which also serves as an exterior housing, a rotational force generating means housed in this housing, and a It has a plurality of rotating shafts C1 to C3 that are rotated by receiving rotational force, and a permanent magnet d fixed to the tips of these rotating shafts near the outer wall of the housing, and all of the rotating force generating means When a rotational force is generated, each rotating shaft and each magnet fixed thereto are rotated in a predetermined direction.

Further, each wheel B has a permanent magnet or a magnetic body e fixedly attached to one end surface of the wheel B, which corresponds to each magnet of the driving body. Since the purpose of the drive body magnet and wheel magnet is to connect the wheel by attractive force simply by bringing the wheel close to the side of the housing, permanent magnets may be attached to both the drive body and the wheel. However, a permanent magnet may be attached to either one and a magnetic body may be attached to the other. Therefore, hereinafter, it will simply be referred to as a magnet. However, it is desirable to provide permanent magnets on both sides to prevent them from falling off while the traveling toy is running.

A more specific configuration of the drive body will be described in detail with reference to FIG. 2. The housing a has a lid 2 fitted onto the top surface of a box-shaped substrate l with an open top, and these are connected by screws or the like or by gluing. It is formed. A rectangular bearing plate 4 and a rectangular bearing plate 5 are erected inside the housing a, and between the bearing plates 4 or by these bearing plates 4.5, the rotational force generating means b and the rotating shafts 01 to A transmission means f for transmitting the rotational force of C3 and the rotational force generation means to the rotating shaft is attached.

The rotational force generating means may be a known spring drive unit that winds up the mainspring using a winding fitting inserted through a hole provided in the housing, but in the preferred embodiment shown, one rotational force generating means is used. A motor is used as a Therefore, hereinafter, it will be referred to as a motor instead of the rotational force generating means.

The housing a is equipped with a power supply circuit that connects the motor to a dry battery housed in a battery compartment 6 that can be opened and closed on the bottom surface of the board l. A switch 7 is provided.

This switch 7 is attached to the upper surface of a mounting plate 8 fixed to the rear upper surface of the bearing plate 4, and the spring contact piece 7a is spaced upward from the fixed contact piece 7b and is always open. Further, above the switch 7, an actuating plate 9 made of a magnetic material connects a protrusion 10 vertically disposed midway in the longitudinal direction with a bearing 11 erected on both left and right sides of the bearing plate 4 through a shaft. As a result, the actuating plate 9 is supported so as to be able to swing around its axis as a fulcrum, and in its natural state, the front part of the actuating plate 9 is held at a position slightly lower than the upper surface of the lid 2 of the housing a by the spring contact piece 7a. has been done.

When the accessory C2 is brought into contact with the front upper surface of the housing with its magnet facing downward, the front part of the actuating plate 9 is attracted by the magnet and lifted, so that the switch 7 is moved by the rear part of the actuating plate. Since the spring contact piece 7a contacts the fixed contact piece 7b and closes the power supply circuit, the motor b rotates.

In the first embodiment, among the rotation axes 01 to c3, CIo
ck' is two front wheels Bl, B2 and two rear wheels B3. B
C3 is a horizontal rotating shaft for rotating the two horizontal rotating shafts, and C3 is a vertical rotating shaft for rotating the accessory B1 attached to the front surface of the housing a.

In the illustrated example, the transmission means f for transmitting the rotational force of the motor b to the rotational shafts 01 to C3 is connected to a gear train 12 installed between the bearing plates 4 and 5 and to the horizontal rotational shaft C1, and Crown gears 131, 132 and pinion 14 are fixed to the rotating shaft C1 and the horizontal rotating shaft C2 and mesh with each other.
It consists of 1,142.

In this way, the rotation of the motor b causes the horizontal rotation axes C1 and C2 to rotate in the same direction, and the vertical rotation axis C3 to rotate around an axis perpendicular thereto.

Furthermore, the housing a has wheel mounting portions gl-g4 on the front and rear sides of the left and right sides of the peripheral wall 3, and one accessory mounting portion g on the front surface.
5 is provided.

The wheel mounting parts all have the same configuration, so one of them is g.
To give a representative explanation of 1, as shown in FIGS. 2 and 5, the wheel mounting portion is installed upright on the base plate 1, and includes a housing wall 16 having a circular recess 15 in the center, and a housing wall 16 in the recess of the housing wall. A magnet d is housed and fixed to the horizontal rotation axis CI at a position slightly near the center from its tip, a truncated conical protrusion 17 fixed to the tip of the horizontal rotation axis C1, and a magnet d.
and a disc 18 rotatably mounted on the horizontal rotation axis c1 between the protrusions 17.

As shown in FIG. 2, semicircular notches 19a are formed in the circumferential wall of the base plate l of the housing a and the circumferential wall of the lid 2 at positions corresponding to the respective wheel mounting parts and accessory mounting parts. 19b is formed, the lid 2 is attached to the substrate 1.
When fitted, a perfect circular opening 19 is formed by both notches,
Only the protrusion 17 and the disc 18 are exposed to the outside through the opening. Therefore, by molding the housing a, the protrusion 17, and the disc 18 from synthetic resin of the same color, it is possible to prevent the magnet d of a different color from being exposed to the outside.

The accessory attachment portion g5 has the same configuration as the wheel attachment portion g1 described above, except that it is provided on the vertical rotation axis c3, so a description thereof will be omitted.

The wheel Bl-B4 also has the same configuration, and as shown in FIG. 4, it consists of a wheel body 20 and a donut-shaped magnet e fixed to the inner surface of this wheel body. An annular flange 21 having an outer diameter smaller than the inner diameter of the opening 19 of the housing and a boss 22 having the same height as the flange at the center of the flange are protrudingly provided on the inner surface of the wheel body. Protrusion 17 of wheel attachment part of drive body A
A concave portion 23 into which the magnet can be fitted is formed, and four donut-shaped portions 24 are formed between the flange and the boss, and a magnet e is fitted into the four portions 24 and fixed by adhesive or the like.

With the above configuration, in order to use the traveling toy according to the present invention for entertainment, the wheel mounting portion g! ~g4
and four wheels B1 to B4 on each accessory mounting part g5.
When the wheels and the accessories C1 are brought close to each other, each wheel and the accessories are attracted by the mutual attraction force of the magnets provided thereon.

In this case, rotate the wheel a little and look at the magnet d of each mounting part.
It is desirable to check whether the magnets of the wheel e and the magnets of different polarities are facing each other to obtain the strongest attraction force.

In this way, after installing the wheels and attaching accessories as desired, another
When the accessory C2, which has a magnet on the lower surface, is brought close, the accessory is held in that position by the attraction force with the internal actuating plate 9, and the switch 7 is closed by the rocking of the actuating plate, so that the motor b is turned on. Power is supplied and it rotates. Therefore, the rotational force of the motor is transferred to the transmission means f, the horizontal rotation axes C1 and C.
2 and magnets d and e to the wheels B, so that the running toy moves on the running surface.

As mentioned above, the disc 18 also has the function of hiding the magnet d of the drive body from the outside, but in order to simply fulfill this function, it is also possible to shield it without providing the opening 19 in the housing a. good. However, when the magnet e of the wheel is rotated by directly contacting the outer wall of the housing, not only does the rotational force transmission rate from the rotating shaft decrease due to friction against the outer wall of the wheel, but also the rotation delay causes a The drawback is that the same magnetic poles of the magnet and the wheel magnet face each other, and the wheel separates from the driving body due to repulsive force, causing the traveling toy to lose its function as a traveling toy. However, since the disk 18 is made rotatable about the rotating shaft, the disk rotates together while being held between both magnets, so the above-mentioned drawbacks are completely eliminated.

In addition, protrusions 17 are provided on the wheel mounting part and the accessory mounting part,
If this is fitted into the recess 23 formed in the center of the end face of the wheel or accessory, even if the traveling toy receives an impact due to irregularities on the running surface while traveling, the impact will be dispersed to the drive body. This has the effect of preventing the wheels from easily coming off due to impact.

As described above, in the traveling toy according to the present invention, the wheels are connected to the driving body by the attraction force of the magnet, and rotational force is transmitted thereto, so that the wheels can be easily attached and detached. Therefore, several types of wheels with different external shapes, patterns, etc. are prepared, and as shown in the drawings of each embodiment later, wheels that match the desired one can be installed or replaced at any time to combine them with the drive body. can be enjoyed.

In the illustrated example, the driving body is formed into a simple rectangular parallelepiped shape, but it is possible to form the housing into various shapes to obtain a traveling toy having a desired appearance and shape.

Second example The second embodiment is shown in FIGS. 6 and 7.

The housing a of the driving body A is formed into a simple box shape, and the driving body is also used as the chassis of the traveling toy v2, to which a body DI of a desired shape is attached. By placing a doll having a magnet on the driver's seat of this body or moving from the passenger seat to the driver's seat, the above-mentioned switch is activated and the traveling toy (2) is caused to travel. In this case as well, by having a variety of bodies available, you can play by changing them at any time.

Third Embodiment In the embodiment shown in FIGS. 8 and 9, the driving body is divided into two parts, front and rear, to form a front driving body AI and a rear driving body A2, and the rear driving body A2 has a first driving body AI and a rear driving body A2. From the driving body to the lateral rotation axis C2 and the rear wheel mounting part g31ga in the embodiment
The front drive body AI has the same configuration as that of the first embodiment except that the horizontal rotation axis C2, the rear wheel mounting part g3 + g4, the gear train 12, and the motor C are removed. It has a similar configuration.

Then, the accessory attachment part g5 of the rear drive body and the accessory attachment part g6 of the front part are magnetically coupled to transmit the rotational force of the motor of the rear drive body to the front part of the drive body. The front wheels connected to the horizontal rotation shaft of the driving body are rotated, and the front driving body is also used as a chassis and is covered with a body D2 having the shape of, for example, a racing car or a sand buggy. When the running toy v3 is completed, the magnetic doll accessory C2 having the shape of the upper body of a racer is placed on the upper surface of the rear drive body through an opening provided in the body, and the switch is operated to make it run.

Fourth Embodiment The embodiment shown in FIGS. 10 and 11 basically has the same configuration as the third embodiment, but the front driving body A3 of this running toy 4 is equipped with a racing car, for example. The front drive unit itself also served as the body.

Therefore, in this case, the body D3 only needs to cover the rear drive body A2, so it can be formed into a relatively small body.

When the drive body is formed separately as in the third embodiment and the i4 embodiment, for example, the front drive body can be made into various lengths and shapes, so that it can be used interchangeably to create a running toy with a different vehicle length. You can also have fun changing it.

Effects of the Invention As described above, the traveling toy according to the present invention connects the rotating shaft of the driving body and the wheels or accessories by using the attraction force between the magnet attached to both or the magnet and the magnetic material. Because of this, it is possible to easily replace wheels with various appearances and enjoy changing the combination of the driving body or the driving body and the body.
