Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a sliding/rotating mechanism in a shape-changing toy, and in particular, the invention relates to a sliding/rotating mechanism for a shape-changing toy, in particular, for rotating a plurality of rotatably connected movable members only in a predetermined direction. The present invention relates to a sliding/rotating mechanism that allows desired changes in shape to be achieved at all times.

(Prior Art) As a conventional shape-changing toy, for example, a plurality of movable members are movably connected, and one movable member is slidably fitted to the other movable member, and during the sliding or Some devices are designed to change the shape by rotating the other movable member at the end. If it is determined that the shape change can only be realized when the other rotating member rotates in a predetermined direction, rotation in the opposite direction is not only unnecessary, but also causes the opposite rotation to occur. There is also a risk that malfunctions due to rotation in this direction may occur frequently and prevent correct play.

(Purpose of the invention) The purpose of the invention is not only to allow one rotating member to rotatably engage the other rotating member, but also to always rotate the other rotating member only in the correct direction. The present invention provides a sliding/rotating mechanism for a shape-changing toy that makes it possible to realize correct shape changes by determining the shape of the shape-changing toy.

(Example) Hereinafter, the sliding/rotating mechanism in the shape-changing toy of the present invention will be explained.

Figures 1a, b and 2 are explanatory diagrams of an embodiment of the main parts of the present invention, in which the first movable member 1

and has.

3, 4, and 5 show an example in which the sliding/rotating mechanism of the present invention is applied to a shape-changing toy, and this shape-changing toy changes from the shape of a car shown in FIG. It is constructed so that it can change into the robot form shown in FIG. The same parts as in FIGS. 1a, b and 2 are denoted by the same reference numerals, and redundant explanation will be omitted.

This shape-changing toy consists of a car body (robot body) 20, a first movable member 1 constituting the rod-shaped part 2, and a second movable member 10 constituting the car front part 21 (robot's toe part). , a front wheel 24 and a rear wheel 25 which are rotatably supported by a wheel holding part (robot arm) 23 whose one end is rotatably supported by a rear wheel axle 22, and which can be opened and closed at the rear of the vehicle body 20. The first movable member 1 is supported by a body base 30 provided on the main body 20 so as to be freely protrusive and retractable in the axial direction, and the second movable member 10 is integrally formed on the back side of the front part 10.

6 and 7 show the first movable member 1 being slidably supported in the front and rear direction, and the rear wheel axle 2
A vehicle body base 30 that supports 2 so as to be able to protrude in and out in the lateral direction.
, a recess 3 formed on the front surface of the vehicle body base 30
The sliding shafts 22 of the movable member 1 and the wheel holder 23 are slidably supported in the recesses 32 formed in the movable member 1 and the side surfaces thereof, respectively.

At the rear end of the rod-shaped portion 2 of the first movable member 1, an engaging protrusion 2a is provided to protrude, and an engaged protrusion 31a is provided to protrude from the inner wall of the support hole 31, so that the rod-shaped portion 2 is temporarily protruded. It may also be configured to prevent it from being easily retracted. Further, an opening/closing part 33 having a robot's face 26 on the inner surface may be pivotally attached to the rear end of the vehicle body base 30. The sliding shaft 22 is supported so as to be slidable in the lateral direction, and also supports the wheel holder 23 so as to be rotatable. wheels 24, 25
is rotatably supported by the wheel holder 23.

In the above configuration, the first
By sliding the protrusion 4 of the movable member 1 along the sliding groove 13 of the second movable member 10, the second
When the movable member 10 as a whole is projected forward, the protrusion 4 reaches the protrusion holding groove 14, and by further rotating the second movable member 10 in the direction of the arrow in FIG. The shape can be changed to the state after rotation shown in FIG. 1b. At this time, the rotation guide portion 16 formed by notching only one side of the inner wall 15 of the sliding groove 13 is connected to the protrusion 4.
Since it is prevented from rotating in the opposite direction, rotation in one direction is always guaranteed, and correct shape change can be realized. When returning from the state shown in FIG. 1b to the state shown in FIG. 1a, the above operation may be performed in reverse. In addition, the protrusion 4 and the protrusion holding groove 14 for holding the protrusion
The shape is not limited to the elongated ellipse as described above, but may be any configuration as long as it can realize the sliding and rotational movements as described above.

Next, when changing from the automobile form shown in FIG. 3 to the intermediate form shown in FIG. 4 to the robot form shown in FIG. After pulling it out completely, remove the protrusion 4 of the first movable member 1 and the second movable member 10.
The second movable member 10 is extended by sliding on the sliding groove 13 of the (vehicle front part 10), and then using the rotation space formed by the rotation guide part 15.
is rotated, and then the protrusion 4 is seated in the protrusion holding groove 14. Next, the sliding shaft 22 is made to protrude from the support hole 32 by pulling out each wheel holding part 23 laterally, and then by rotating the wheel holding member 23, which is an arm, to a desired angle. , the robot's form is completed. If you want to return to the car mode, just do the opposite operation to the above.

(Effect of the invention) As described above, according to the sliding/rotating mechanism of the shape-changing toy of the present invention, one movable member can slide and rotate relative to the other movable member. By determining that the other movable member always rotates only in the correct direction, it is possible to realize correct shape changes.
