 FIG. 1 shows a traveling toy of the embodiment. The traveling toy 1 includes a traveling body 2, a discontinuing track 3 on which the traveling body 2 travels, and a jumping ladder (rotating body) 4 which connects and disconnects the discontinuing portion of the discontinuing trajectory 3. The reference numeral 6 in FIG. 1 indicates the background plate.

Of these, first, the interrupted track 3 will be described. The interrupted track 3 has a downward slope as a whole. Further, the jumping ladder 4 is configured to be able to swing up and down around a predetermined axis at the upper part of the slope of the interrupted track 3 as a center.

According to this running toy 1, the running body 2 is scooped up by the frontmost rung 4a of the jumping ladder 4 at the lower slope of the interrupted track 3, and when the jumping ladder 4 stands up, the rung 4a It is turned by and falls to the upper part of the slope of the interrupted track 3. Then, the traveling body 2 dropped on the upper part of the slope travels on the interrupted track 3 and returns to the lower part of the slope of the interrupted track 3. Here, the traveling body 2 temporarily stops and then waits for the jumping ladder 4 to fall. Then, when the jumping ladder 4 falls down, the traveling body 2 is scooped up again, and the same operation as described above is repeated.

Next, details of the traveling toy 1 will be described.

As shown in FIG. 2, the traveling body 2 is provided with slits 20, 20 extending in the lateral direction and reaching both side surfaces so that the crossbar 4a of the jumping ladder 4 can be received. ing. Further, inside the slits 20 and 20, there are circular lateral holes 21 on both sides which can receive the cross bar 4a of the jumping ladder 4 and allow the running body 2 to turn around the cross bar 4a. It is provided to reach. Further, a doll 23 is attached on the traveling body 2, and one wheel 24 is provided on the front side and one wheel on the lower side. The wheel 24 is made of a heavy material such as brass or iron so as to function as a weight. In this embodiment, there are two traveling bodies 2 configured in this manner.

As shown in FIG. 1, the interrupted track 3 includes a first interrupted track 30 and a second interrupted track so that the two traveling bodies 2 and 2 can simultaneously run on separate tracks. 31 and 31. The first interrupted track 30 and the second interrupted track 31 each have a downward slope from one end to which the jump ladder 4 is attached to the other end. As shown in FIG. 3, a stopper 33 is provided at the lower part of the slope of the first interrupted track 30 and the second interrupted track 31. The stopper 33 is also used as the first interrupted track 30 and the second interrupted track 31, and is configured to be retractable in both tracks. The stopper 33 can lock the traveling body 2 when protruding. This stopper 33 is normally projected into the track by a pulling spring (biasing means) 34 (Fig. 3 (a)), and when the jumping ladder 4 falls down, the stopper 33 presses the tip of the jumping ladder 4 to move the track. It is supposed to sink inside (Fig. 3 (b)).

The jump ladder 4 has the same width as the combined width of the first interrupted track 30 and the second interrupted track 31 so that the two traveling bodies 2, 2 can be scooped up at the same time. There is. Further, as shown in FIGS. 1 and 4, the jumping ladder 4 has not only the columns 42a and 42a on both sides but also the column 42a in the middle. If the columns 42a, 42a on both sides are provided, the column 42a in the middle is not always necessary, and if the column 42a in the middle is provided, the columns 42a, 42a on both sides are not necessarily required. The point is that the structure is such that the cross bar 4a can be sufficiently supported. In the present application, all of these aspects are referred to as “jumping ladder”. In addition, the cross-section 42a of the frontmost rung 42a of the jumping ladder 4 is formed in a rhombic shape as shown in FIG. 3 (b).

Next, the bearing device of the jumping ladder 4 will be described. As shown in FIG. 4, the jumping ladder 4 is supported so as to be sandwiched by a rotating disk 44 and an indenter 45. . As shown in FIG. 5A, the rotary disc 44 is provided with a large number of engaging projections 44a at concentric positions with a predetermined angular interval. A large number of engagement holes 49a (see FIG. 6) that fit into the engagement protrusions 44a are formed on the side surface. Further, as shown in FIG. 5B, the indenter 45 is provided at a position facing the rotary disk 44. The indenter 45 is urged toward the rotary disc 44 by a push spring 46. A shaft projection 45a is attached to the center of the indenter 45. The shaft projection 45a is fitted into a shaft hole 49b (see FIG. 6) on the side surface of the jumping ladder 4 so that the jumping ladder 4 rotates (swings) around the shaft projection 45a. . Since the jumping ladder 4 is only sandwiched between the rotary disc 44 and the indenter 45 by the push spring 46, the jumping ladder 4 can be easily moved by moving the indenter 45 away from the rotary disc 44. In addition to being removable, when an unreasonable load is applied to the jumping ladder 4, the indenter 45 moves in a direction away from the rotating disc 44. As a result, it is not necessary to provide a special clutch mechanism inside the support base 5.

An inclined plate 47 for erecting the traveling body 2 is provided at the base end portion of the jumping ladder 4. Further, as shown in FIG. 6, a triangular projection 48 is provided at the base end of the jumping ladder 4, while the support base 5 is provided with an elastic contact portion 35 that abuts against the projection 48. ing.

Further, as shown in FIG. 4, an operating means 50 (see FIG. 7) for operating the jumping ladder 4 is installed in the support base 5 that supports the interrupted track 3. . The operating means 50 has a motor M (see FIGS. 4 and 8). A gear 51a is attached to the shaft of the motor M as shown in FIG. 8, and the rotational power of the motor M is transmitted to the eccentric cam 52 which is attached coaxially with the gear 51h through the gears 51a to 51h. It has become. The eccentric cam 52 is inserted into a hole 53a of a ladder lever 53 which is a follower. The ladder lever 53 is swingable around a shaft 54 (see FIG. 4), and is configured to reliably follow the operation of the eccentric cam 52 by a spring 55. A partial gear 53b is provided at the tip of the ladder lever 53. The partial gear 53b meshes with a gear 56 provided coaxially with the rotary disk 44.

In the traveling toy 1 configured as described above, when the stopper 33 is submerged in the track by the jumping ladder 4, the traveling body 2 advances from the state shown in FIG. 9A and is shown in FIG. 9B. Thus, the cross bar 4a of the jumping ladder 4 enters the cross hole 21 of the traveling body 2. When the jump ladder 4 is raised in this state, the traveling body 2 is scooped up as shown in FIGS. 9 (c), 9 (d) and FIGS. 10 (a), 10 (b). Then, when the jumping ladder 4 is lifted up to the top, the projection 48 of the jumping ladder 4 abuts on the elastic contact portion 35, whereby the traveling body 2 is moved to the elastic contact portion 35 as shown in FIGS. The wheels 24 rotate in the direction in which they are present. When the traveling body 2 makes a half rotation, the traveling body 2 is disengaged from the cross bar 4a, and the lateral hole 4a on the rear side of the traveling body 2 engages with the cross bar 4a one step lower (FIG. 11 (c)). After that, the traveling body 2 rotates in the direction in which the wheels 24 exist. When the traveling body 2 is detached from the last cross bar 4a by repeating such an operation, the traveling body 2 is erected by the inclined plate 47. Then, it is thrown to the upper part of the slope of the interrupted track 3.

According to the traveling toy 1 configured as described above, the traveling body 2 is scooped up by the jumping ladder 4 at the lower part of the slope, and is dropped while rolling by the cross bar 4a of the jumping ladder 4, It is possible to realize a traveling toy that is rich in action. Further, since the stopper 33 is provided so as to stand by, the traveling body 2 can be reliably picked up even if the operation of the jumping ladder 4 or the traveling speed of the traveling body 2 is slow. Further, since the projection 48 and the elastic contact piece 35 are in contact with each other, the traveling body 2 can be surely dropped.

Although the embodiment made by the present inventor has been described above, the present invention is not limited to the embodiment and various modifications can be made without departing from the scope of the invention. There is no end.

In the above embodiment, the jumping ladder 4 is given as an example of the “rotating body”, but the “rotating body” in the present application is a concept including all members that rotate about a predetermined axis. is there.
