Description

[Detailed description of the invention] The present invention is equipped with a driving wheel power device and configured to be able to be folded and unfolded freely, and is capable of automatically unfolding an operating toy such as the Chappell Bulldozer-1 and other toys similar to these toys, and making it travel at variable speeds. Regarding equipment.

Traveling toy cars that automatically fold and unfold are known, but they have a relatively complex structure, require a lot of effort to manufacture, and do not operate smoothly.

The present invention is intended to provide a toy that eliminates these conventional drawbacks and has a device that operates smoothly with a simple mechanism.

The present invention will be explained with reference to the embodiment shown in the drawings. 1 is a vehicle body frame equipped with a shovel 2 on the upper surface which is designed to be freely unfoldable and foldable, and a handle 4 is pivotally supported on a support shaft 3. .

Reference numeral 5 denotes a hook that is engaged with a retaining portion 6 provided on the bottom surface of the shovel 2, and is provided on the upper surface of the rear end of a sliding plate 7 installed on the vehicle body frame.

8 is a tension spring that pulls the sliding plate 7 forward; 9 is a machine frame of a driving wheel power system 10 installed inside the vehicle body frame; 11
12 is an idle front wheel; 12 is a rear wheel fixed to an axle 13; on the rear axle 13, a gear 15 with a pinion 14 integrally provided on one side is slidably attached; An engagement hole 17 is provided for engaging and disengaging a clutch 16 fixed above.

The gear 15 is related to a pinion 19 on the driving wheel shaft 18 via a transmission intermediate gear.A shaft 21 of a transmission gear 20 in the intermediate transmission gear is supported in a bearing elongated hole 22.

23 is provided with a gear 24 at one end that engages and disengages from the pinion 14,
The drum is provided with a disk-shaped side plate 25 on the other side, and is loosely supported between the machine frames by a support shaft 26.

The drum is provided with an engaging protrusion 28 that engages and disengages with an engaging protrusion 27 provided on the bottom surface of the sliding plate 7.

29 is a pawl whose base is pivotally supported on the rear axle 13, and has a locking pawl 31 on the upper surface of the front end that engages and disengages from an engaging notch 30 provided at the edge of the side plate 25.

Further, a bearing recess 32 is provided at the front end of the pawl 29, into which the shaft 21 of the gear 20 is fitted.

Reference numeral 33 denotes a tension spring that keeps the locking pawl 31 of the pawl 29 in constant contact with the edge of the side plate 25.

The reference numeral 34 is a pressure spring for constantly engaging the gear 15 with the clutch 16, and the reference numeral 35 is a toothless portion provided at a predetermined position of the gear 24 to interrupt the engagement with the pinion 14. .

Since the present invention is constructed as described above, the shovel 2 is rotated on the upper surface of the vehicle body frame 1 as shown by the solid line in FIG. , Hikihane 33
After the shovel 2 to be rotated and deployed is latched at the position shown by the chain line, the rear wheels 12 are rubbed on the floor surface like a normal driving wheel power device to give high speed rotation to the driving wheels.

At this time, the gear 15 is wedged with the clutch 16 by the action of the pressure spring 34 as shown in FIG.
3, and therefore the rotation of the rear axle is transmitted to the pinion on the driving wheel shaft through the intermediate transmission gear meshing with the gear 15, thereby transmitting the rotation to the driving wheels.

During this time, the pawl 29 is engaged with the engagement notch 30 of the side plate 25, and the gear 24 and pinion 14 are not engaged with each other, so the drum 23 remains in a stopped state.

If the wheels are placed on the floor together with the vehicle body when the driving wheels are sufficiently rotated, the rotation of the rear wheels will be resisted by the weight of the entire vehicle frame, so the gear 15 will be moved by the clutch 16.
(See Fig. 5) At the same time, the pinion 14 meshes with the gear 24, so the drum 23 rotates. , the engaging protrusion 28 provided on the drum engages with the engaging protrusion 27 on the rotation path and slides the sliding plate 7 backward, so that the hook 5 on the upper surface engages with the engaging part 6 of the shovel 2. As a result, the shovel 2 is expanded from the state shown by the solid line in FIG. 1 to the state shown by the chain line under the action of the tension spring 33.

At this time, the gear 15 and clutch 16 of the car body disengage,
Since the resistance suddenly disappears, the vehicle suddenly changes gears.

The present invention operates as described above, but by folding the unfolded shovel back to its original state and hanging it on the vehicle body frame, the user can have fun repeating the above-mentioned actions.

The present invention operates as described above, is easy to handle, can be easily operated by young children, is safe, and is particularly simple in structure so that it is less likely to break down, making it suitable as a toy for young children.
