Description

[Detailed explanation of the invention] This invention relates to a toy running car to be used in a place exposed to sunlight.The purpose of this invention is that if it is left in a place exposed to sunlight for a certain period of time, the bimetal for the running lock will become exposed to sunlight. To provide a highly interesting traveling toy car which is unlocked by condensed heating and starts running by rubber power.

In order to achieve this object, the toy traveling vehicle of the present invention is a toy vehicle which has a drive wheel rotatably driven by rubber power and a non-driven driven wheel, and a ratchet gear is provided in the rubber power transmission system of the drive wheel. a rotary lever having a bimetallic engagement portion with a ratchet pawl that engages and disengages the ratchet gear and is supported by a pin within the toy vehicle body so as to be rotatable in the direction of engaging and disengaging the ratchet pawl; an elastic body that rotates and biases the ratchet pawl in the direction of release; a reflective mirror surface provided on the outer surface of the toy car body that reflects and focuses sunlight on a bimetal-equipped portion; The bimetal is provided with a base end fixed to the toy car main body and a free end that curves outward by condensed heating of sunlight. It has a latch pawl that engages with the engaging portion and rotationally locks the rotary lever in the ratchet pawl engaged state, and when the bimetal latch pawl is disengaged due to condensed heating of sunlight, The toy car is characterized by being powered by rubber power.

Hereinafter, one embodiment of this invention will be described with reference to the drawings. In the drawing, 1 is a ladybug-shaped drive wheel 3 which is rotatably driven by the power of a rubber string 2, and non-driven driven wheels 4 and 5. In the toy car body, the rubber power transmission system of the drive wheel 3 is provided with a ratchet gear 6 coaxially formed integrally with the drive wheel 3. The drive wheel 3 with a ratchet gear is rotatably supported by a bearing 7 as shown in FIG.
A rubber string 2 stretched between the rubber hanging portion 9 on the main body side is wound up by a wheel handle rod 10, and rotational power is accumulated. Reference numeral 11 denotes a rotary lever having a ratchet pawl 12 that engages and disengages from the ratchet gear 6 and a bimetal engaging portion 13, and is pivotally supported within the toy car body 1 by a pin 14 so as to be rotatable in the direction of engaging and disengaging the ratchet pawl. The rotary lever 11 is urged to rotate in the direction in which the ratchet pawl 12 separates from the ratchet gear 6 by an elastic body 15 made of a rubber string.

Reference numeral 16 denotes a reflective mirror surface provided on the outer surface of the toy car body 1 to reflect and condense sunlight onto the bimetal disposed portion. Although it is formed by attaching a curved reflecting plate 17, it may also be formed by applying reflective paint to the inner surface of the main body recess 1a. Reference numeral 18 denotes an elongated strip-shaped bimetal that is disposed at the condensing portion of the reflective mirror surface 16 and curves outward by condensed and heated sunlight.The base end of this bimetal is inserted into the toy car main body 1b. A latch that is fixed and is a free end engages with the bimetal engaging portion 13 of the rotary lever 11 as shown in FIG. 3, and locks the rotary lever 11 in the ratchet claw engagement state. The claw 19 is bent.

In the figure, reference numeral 20 indicates an engagement/disengagement hole for the bimetal hook 19 provided in the upper end wall of the main body recess 1a, and reference numeral 21 indicates a lever set knob for manually rotating and setting the rotating lever 11 in the bimetal engagement direction. , protrudes outward from the main body window hole 22 as shown in FIG. 23
is a diagonal shading rod that is attached to the top of the main body 1 so that it can be raised and lowered, and when the toy car main body 1 is rotated and installed so that the shadow formed by this shading rod 23 is located on the set instruction line 24. , the reflecting mirror surface 16 can be set in a state in which it is correctly oriented in the direction of sunlight.

Therefore, if the vehicle is left in a place exposed to sunlight for a while in the above-mentioned set state, the bimetal 18 for the traveling lock will be heated by the concentrated sunlight.
As shown by the imaginary line in the figure, the bimetallic locking pawl 19 is disengaged from the bimetal engaging portion 13 of the rotary lever 11, and the rotary lever 11 is thereby moved from the elastic body 15. Due to the urging force, it rotates clockwise in FIG. 3, and the ratchet pawl 12 disengages from the ratchet gear 6. In this state, the drive wheel 3 is unlocked and the toy car is driven by the rubber power. Starts running.

Since the traveling car toy of this invention has the structure described above, if it is left in a place exposed to sunlight for a certain period of time, the bimetal for the traveling lock will become unlocked due to the concentrated heating of the sunlight. Therefore, it is possible to provide a highly interesting traveling vehicle toy with a novel configuration that does not exist in the past, in which the toy vehicle starts running using rubber power.
