More specifically, the swinging arm 80 is provided with a locking piece 81, which is clockwise with respect to the locking gear 79 that rotates counterclockwise in FIG. , The locking piece 81 fits between the gears of the locking gear 79 from above and is locked. Thus, a locking gear train is formed from the second idler small gear 64 and the second idler large gear 65 that rotate coaxially to the locked gear 79 via the fixed small gear 66 and fixed large gear 77 that rotate coaxially. . In this embodiment, for example, a ratchet gear is used as the locking gear 79.

  In addition, on the inner side surfaces of the male frame 53, the female frame 55, and the intermediate frame 56, recesses and the like for supporting the shaft portions of various gears are provided.

  Further, the cutout portion 52 of the housing case 51 is opened in a range where the operating arm 33 can enter the housing case 51 and can be directly or indirectly locked to the locking gear 79. In this embodiment, the notch 52 is formed so as to open a large space between the male frame 53 and the intermediate frame 56.

  Next, traveling and stopping of the mainspring traveling toy 1 will be described. When winding the mainspring in the drive unit 50, as shown in FIG. 5, the rear wheel 13 is rotated backward while being pressed against the road surface or the like, and the drive gear 57 is rotated clockwise. Then, the transmission large gear 58 rotates counterclockwise, and in conjunction with this, the first idle gear 59 moves downward in the inner first elongated hole 62 and the outer first elongated hole 63 toward the mainspring small gear 60 side. And mesh with the mainspring small gear 60. Thereby, the mainspring small gear 60 rotates counterclockwise, and the mainspring is wound up.

  At this time, as shown in FIG. 6, in the traveling gear train, the third play small gear 71 rotates clockwise by the rotation of the mainspring large gear 70, and the third play large gear 72 is transmitted in conjunction with this. It moves upward in the elliptical recess 75 and the inner third elongated hole 76 so as to be separated from the small gear 73, and rotates while meshing with the mainspring large gear 70. Thereby, the rotation output from the third play large gear 72 to the transmission small gear 73 is blocked.

  Further, as shown in FIG. 5, in the locking gear train, the second play small gear 64 rotates clockwise by the rotation of the transmission large gear 58, and the second play large gear 65 is fixed in conjunction with this. The inner second elongated hole 68 and the outer second elongated hole 69 are moved upward so as to be separated from the small gear 66, and rotate while meshing with the transmission large gear 58. As a result, the rotational output from the second idler large gear 65 to the fixed small gear 66 is blocked.

  Next, when the wound spring is released, as shown in FIG. 8, the third play small gear 71 rotates counterclockwise by the clockwise rotation of the mainspring large gear 70, and in conjunction with this, The third play large gear 72 moves downward in the elliptic recess 75 and the inner third long hole 76 toward the transmission small gear 73, and the third play large gear 72 rotates while meshing with the transmission small gear 73. . As a result, as shown in FIG. 7, the transmission large gear 58 meshes with the drive gear 57, whereby the drive shaft 14 rotates counterclockwise, and the mainspring traveling toy 1 runs.

  At this time, as shown in FIG. 7, in the traveling gear train, the mainspring small gear 60 is rotated clockwise by the rotation of the mainspring large gear 70, and the first idle gear 59 is interlocked with the mainspring small gear 60. And move upward in the inner first elongated hole 62 and the outer first elongated hole 63 so as to separate from the mainspring small gear 60, and the rotation from the mainspring small gear 60 to the transmission large gear 58. The output is cut off.

  Further, as shown in the figure, in the locking gear train, the second play small gear 64 is rotated counterclockwise by the rotation of the transmission large gear 58, and the second play large gear 65 is interlocked with this rotation. It moves downward in the inner second long hole 68 and the outer second long hole 69 toward the fixed small gear 66, and the second idle large gear 65 rotates while meshing with the fixed small gear 66. Thereby, as shown in FIG. 8, the locking gear 79 rotates counterclockwise via the fixed large gear 77 and the small gear 78. At this time, since the locking gear 79 rotates counterclockwise, the locking piece 81 of the swing arm 80 is pushed upward in the rotation direction. The rotation of 79 is not stopped.

  In the mainspring-type traveling toy 1 that is traveling, the detection means 20 and the locking means 30 are operated by the power of the battery 15 by switching a predetermined switch (not shown) provided in the chassis 10 in advance. be able to.

  Specifically, the mainspring-type traveling toy 1 that is running approaches the obstacle W in front to a certain distance, and the light projected toward the front by the infrared sensor 21 strikes the obstacle W, and the reflected light is received. When 22 is detected, this electric signal is sent to the locking means 30 to activate the solenoid 31.

  As a result, the rotating shaft 32 of the solenoid 31 is rotated to rotate the operating arm 33 counterclockwise as shown in FIG. Press downwards. Then, the swinging arm 80 rotates clockwise around the shaft portion 82, so that the locking piece 81 fits between the gears of the locking gear 79 from above and is locked. That is, the rocking arm 80 is used to indirectly lock the locking gear 79. Accordingly, the rotation of the gears in the locking gear train is stopped, the rotation of the gears in the traveling gear train is stopped, and the mainspring traveling toy 1 stops.

  More specifically, when the locking piece 81 of the swing arm 80 is locked between the gears of the locking gear 79, the rotation of the locking gear 79 is stopped, and accordingly, a locking gear train is formed. The rotation of the second play large gear 65 is also restrained. Since the rotation of the second idler small gear 64 that rotates coaxially with the second idler large gear 65 is similarly inhibited, the rotation of the transmission large gear 58 that meshes with this is inhibited, so that The driving force is not transmitted to the drive gear 57, and the mainspring traveling toy 1 stops.

  Then, when the user removes the obstacle W or the like and the detection means 20 is in a state where it does not detect the obstacle W, the electrical signal sent from the receiving unit 22 to the solenoid 31 via the base 40 is cut off. . As a result, when the rotation shaft 32 of the solenoid 31 is rotated, the operating arm 33 is rotated clockwise to be in the initial state. As a result, since the locking state of the locking gear 79 is released, the mainspring traveling toy 1 travels again within the range where the mainspring driving force remains.

  As described above, according to the spring-type traveling toy 1 according to the present invention described above, the locking gear train interlocked with the traveling gear train is used, and the locking piece 81 is fitted between the gears of the locking gear 79 by the locking means 30. By forcibly stopping the rotation of the gear, it is possible to stop the traveling gear train interlocking with the gear. That is, since the traveling gear train can be surely stopped by locking the locking piece 81 to the locking gear 79 via the operating arm 33 that is operated by electric power, Even in the road surface condition, traveling can be automatically stopped in front of the obstacle W.

  Further, the locking gear 79 and the swing arm 80 are provided inside the housing case 51, and the operating arm 33 is operated from the outside of the housing case 51 via the notch 52, so that the drive unit 50 is compact. Can be achieved.

  Furthermore, since the locking gear train is configured to be disengaged from the traveling gear train when the mainspring is wound up and to be engaged with the traveling gear train when the mainspring is released, the load during the winding of the mainspring is reduced, and the operability is reduced. And the durability of the gear train can be improved.

  In the embodiment described above, the locking gear 79 is indirectly locked by the operating arm 33 via the swing arm 80, but is not limited thereto. For example, the operating arm 33 can be directly locked without providing the swing arm 80. When these are directly or indirectly locked, the operating arm 33 is of course an appropriate shape and is not particularly limited.

  Further, in particular, when directly locking, the operating arm 33 can be locked so as to move directly without rotating the operating arm 33, but is not limited thereto. Further, the locking gear 79 can be provided so as to be exposed from the notch 52 to the outside of the housing case 51. That is, the present invention is not limited to the inside of the housing case 51, and it is only necessary that the locking gear 79 is configured to be locked directly or indirectly by moving the operating arm 33.

  Furthermore, in the above-described embodiments, the arrangement, dimensions, materials, and the like of the winding gear train, the traveling gear train, and the locking gear train can be changed as appropriate. Furthermore, it is needless to say that a part of the configuration can be omitted or a part of the configuration can be extracted.
