Description

[Detailed description of the invention] (Industrial field of application) The present invention is a wall that can be moved along the side wall surface of the wall piece on a running base where the wall piece can be arranged and changed as needed. This relates to a traveling toy.

(Prior Art) Conventionally, various wall-running toys of this type have been provided. For example, an appropriately devised sensor device is attached as a means to run along a wall,
There are toys that are configured so that the direction can be changed automatically, and there are running toys that can change direction as described in Japanese Utility Model Publication No. 46-4263. This traveling toy that can freely change direction is equipped with rotating wheels at the front corners of both sides of the traveling body, and sliders for changing direction are protruded from approximately the center of both sides. , the traveling body is configured to move straight. In other words, when the rotating wheel of the traveling body and the direction-changing sliding tool come into contact with the guardrail, the direction-changing sliding tool acts as a fulcrum to direct the front of the traveling body toward the guardrail, a so-called direction-changing action. This is combined with the straight traveling action of the traveling body to cause the traveling body to travel obliquely forward (in the diagonal direction), and the rotating wheel installed at the front corner of the traveling body located in the diagonal direction Then,
The rotary wheel and the sliding tool for changing direction move forward while constantly contacting the guardrail, and the traveling body runs along the guardrail and automatically turns at the end of the guardrail.

(Problems to be Solved by the Invention) However, in the case of a device equipped with an appropriately devised sensor device as described above, the structure tends to be complicated and it is expensive.
Moreover, if the running path is made complicated, there are problems such as the inability to run reliably and smoothly along walls. In addition, in the case of a traveling toy that can freely change direction as described above, the running route may be complicated (the guardrail arrangement is complicated) or the running route may be narrow (for example, in a dead-end alley with approximately the same width as the running object). If the vehicle enters the guardrail or if the vehicle comes into direct contact with the guardrail, the vehicle may not be able to travel along the guardrail or may become unable to travel. Moreover, since the sliding tool for changing direction travels while contacting the guardrail, the sliding tool for changing direction travels in a state where it is caught on the guardrail, which significantly reduces the traveling speed of the traveling body itself. Along with this, there was a problem that the running body could not be expected to move smoothly.

(Means for Solving the Problems) Therefore, the present invention aims to eliminate the above-mentioned difficulties that existed in the past, to simplify the configuration of the running toy itself, and to solve the problems even on complicated and narrow running paths. This was devised to ensure reliable and smooth running, and specifically, to properly transmit its own rotational force onto the running roadbed A to cause the running body 1 to advance diagonally forward. Driving Drive wheels 11 for traveling that rotate vertically are provided at the bottom of the traveling body 1, and their rotational force is appropriately transmitted to the side wall surface of the wall piece B erected on the running roadbed A to assist the forward movement of the traveling body 1. At the same time, a pair of left and right direction change rotors 20 and 21, which are driven and horizontally rotated in a predetermined direction, are placed on the left and right sides of the bottom front of the traveling body body 1 so that the traveling body body 1 can change direction freely along the side wall surface. We adopted a method to provide this information.

(Example) The present invention will be described below with reference to illustrated examples.

The wall-travelling toy of the present invention has running drive wheels 11 that are driven and vertically rotated by a drive mechanism built in the running body 1 and are mounted at an appropriate angle with respect to the forward direction of the running body 1 at the bottom of the running body 1. The rotating force of the main body 1 is appropriately transmitted to the running roadbed A, so that the main body 1 of the running body 1 runs diagonally forward (left front or right front) straight or while making a large turn. , formed so as to obtain a force that moves the traveling body main body 1 in the forward direction and a force that acts to continue pushing the traveling body main body 1 against the side wall surface of the wall piece B on the left side or the right side. do. Furthermore, the drive mechanism built into the traveling body 1 drives horizontal rotation (left rotation, or A pair of left-right direction change rotating bodies 20 and 21 are formed, and the side circumferential surfaces thereof contact the side wall surface of wall piece B erected on running roadbed A. The bodies 20 and 21 assist the traveling body 1 in moving forward, and are configured so that the traveling body 1 can freely change direction along the side wall surface of the wall piece B. The pair of direction change rotating bodies 20 and 21 are provided on the left and right sides of the bottom front of the traveling body body 1, and one of the direction changing rotary bodies 20 is provided in the traveling direction of the traveling body body 1 (front left direction,
Alternatively, the other rotating body 21 for direction change is arranged in front of the driving wheel 11 for driving and along the front right direction) and in front of the driving wheel 11 for driving. As a reference, it is disposed at a position symmetrical to the direction changing rotating body 20 (front right direction or front left direction).

The drive mechanism includes a worm wheel 14 that meshes with a worm 13 fixed to the tip of the rotating shaft of the motor 12, and a small gear 16 fixed to the lower end of a shaft 15 to which the worm wheel 14 is fixed at the upper end. , meshing with this small gear 16 and appropriately decelerating and rotating the driving drive wheel 11 fixed to the other end of the wheel shaft 18 via the crown gear 17 fixed to one end of the wheel shaft 18; Further, a worm wheel 22 that meshes with the worm 13, and a worm wheel 22 that meshes with the worm 13;

In the figure, reference numeral 50 denotes a locking protrusion that can be locked in a locking groove 51 provided on the bottom surface of the head of the main body 1 of the traveling body. It is designed so that it can be attached and detached freely.

The present invention is constructed as described above. Next, an example of its use will be explained. First, wall pieces B are arranged on a running track board A in a freely changeable layout to form a running track in the form of a maze. When a running toy is placed on this track and the left arm 40 is swung downward to energize the motor 12 of the drive mechanism and the worm 13 rotates, the worm wheel 14, shaft 15, small gear 16, crown gear 17, and wheel shaft 18
The running drive wheel 11 is decelerated and rotated via the worm wheel 22, small gear 23, large gear 24, and shaft 25, and one of the direction changing rotating bodies 20
rotates at a reduced speed, and the intermediate gear 26 and gear 2
7. The other direction changing rotating body 21 is decelerated and rotated via the shaft 28, and the right arm 35 is rotated via the cam 38.
The machine moves while repeatedly rocking up and down.

When the traveling body 1 runs straight along the side wall surface of the wall piece B as shown in FIG. 5A,
A force that tries to bring the side circumferential surface of one of the direction changing rotary bodies 20 into contact with the side wall surface of the wall piece B due to the rotation of the traveling drive wheel 11, and a force that tries to move the traveling body main body 1 in the forward direction. As the force acts, the rotation of one of the direction changing rotating bodies 20 causes the traveling body main body 1 to
The force that tries to move the column in the forward direction and the support column 30
A force acts to bring the side circumferential surface into contact with the side wall surface of the wall piece B, and the traveling body main body 1 runs along the side wall surface of the wall piece B in the forward direction without separating from the side wall surface.

Further, when the traveling body main body 1 turns to the left along the side wall surface of the wall piece B as shown in FIG. Once the surface is separated from the side wall surface of the wall piece B, the side wall surface corner of the wall piece B comes into contact with the outer surface of the rib 32 by the traveling drive wheels 11, and the rib 3
The corner of the side wall surface of the wall piece B temporarily fits into the recess formed at the connecting portion between the support 2 and the support 30, and the traveling body main body 1 turns to the left around this recess. Then, after the side circumferential surface of one of the direction changing rotating bodies 20 comes into contact with the side wall surface of the wall piece B, it resumes running in the forward direction as shown in FIG. 5A.

Furthermore, when the traveling body main body 1 changes direction to the right along the side wall surface of the wall piece B as shown in FIG. , 21 side peripheral surfaces come into contact almost simultaneously,
As the traveling body main body 1 turns to the right in an attempt to change direction to the right, the side circumferential surface of the other direction-changing rotary body 21 separates from the side wall surface of the wall piece B, and the traveling body 1 moves by the one direction-changing rotary body 20. When the main body 1 further turns to the right and the outer peripheral surface of the support column 30 comes into contact with the side wall surface of the wall piece B, the traveling main body 1 runs in the forward direction. Note that, at this time, since the traveling drive wheels 11 appropriately slip between themselves and the floor surface, they do not impede the force with which the traveling body body 1 attempts to change direction. In addition, when the running path is in the shape of a dead end and the side wall surface of the wall piece B is continuously bent to the right at a relatively short interval, the other direction changing rotating body 21 may be moved away from the first side wall surface. When it comes into contact with the next side wall surface, it operates together with one of the direction changing rotating bodies 20 that is in contact with the first side wall surface to smoothly turn the traveling body 1 to the right. . In other words, it is possible to change direction reliably and quickly even in a relatively narrow passage.

(Effect of the invention) Therefore, according to the wall-running toy of the invention,
Vertically rotating driving drive wheels 11 are provided at the bottom of the traveling body body 1 so that the vehicle's own rotational force is appropriately transmitted onto the running roadbed A to cause the traveling body body 1 to advance obliquely forward. The power is transmitted to the side wall surface of wall piece B erected on the running roadbed A to assist the forward movement of the traveling body body 1, and is also driven in a predetermined direction so that the traveling body body 1 can freely change direction along the side wall surface. A pair of horizontally rotating rotating bodies 20 for changing left and right directions;
21 are provided on the left and right sides of the bottom front of the main body 1 of the running body 1, so when the running track formed by the wall pieces B erected on the running track board A is complicated, or when this running track is narrow (for example, when running If the running body 1 enters a dead-end road with a width that is approximately the same as the width of the main body 1, or if the running body 1 enters a wall piece B
Even if it comes into direct contact with the side wall surface of the main body 1, the main body 1 will not become unable to run.
It is possible to reliably run along the side wall surface of the wall piece B. In addition, there is no longer a need for a sensor device for changing direction as in the past, and the running toy itself can be simplified, making it easier and cheaper to manufacture the running toy. Therefore, failures are less likely to occur.

In addition, since the traveling drive wheels 11 are provided at the bottom of the traveling body body 1 and are driven and rotated vertically so that the rotational force of the traveling body body 1 is appropriately transmitted onto the running roadbed A to cause the traveling body body 1 to advance diagonally forward. Even if the main body 1 is operated away from the side wall surface of the wall piece B, the traveling body main body 1 travels diagonally forward straight or while making a large turn, comes into contact with the side wall surface of one of the wall pieces B, and then runs along the wall. You will be able to run. Moreover, the traveling body 1
The force that moves the body in the forward direction and the force that acts to keep pushing one direction-changing rotary body 20 against the side wall surface are reliably obtained, and one direction-changing rotary body 20 is pushed against the wall piece B. The traveling body main body 1 can now travel forward without leaving the side wall surface.

In particular, the driving drive wheels 11 are
In addition to assisting the forward movement of the traveling body body 1, the traveling body body 1 can freely change direction along the side wall surface, so that the traveling body body 1 can move forward on the side of the wall piece B without reducing the running speed of the traveling body body 1 itself. It becomes possible to move along the wall surface (advancement or direction change), and it also becomes possible to move the wall piece B along the side wall surface extremely smoothly.

As explained above, according to the present invention, there is no need for a sensor etc. for running along the wall, the configuration is simplified, and the running along the wall can be performed reliably and smoothly, making it more interesting for children. The game is fun to play, and can be provided at a low price, making it extremely useful in practice.
