Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples.

Referring to fig. 1, 2 and 3, an up-down axial direction D1, a left-right axial direction D2 perpendicular to the up-down axial direction D1, a front-back axial direction D3 perpendicular to both the up-down axial direction D1 and the left-right axial direction D2, and a vertical axis L extending along the up-down axial direction D1 are defined. One embodiment of the walkabout toy of the present invention is adapted to be placed on a cord (not shown) disposed along the fore-aft axis D3. The walking toy comprises a driving unit 1, a balancing unit 2, and a walking unit 3.

Referring to fig. 2, 3 and 4, the driving unit 1 includes a body 11, a first output shaft 12 connected above the body 11 along the vertical axis L and capable of rotating around the vertical axis L relative to the body 11, and a second output shaft 13 connected below the body 11 along the vertical axis L and capable of rotating around the vertical axis L relative to the body 11. In the present embodiment, the driving unit 1 is substantially a motor supplied with electric energy by a plurality of batteries (not shown). In addition, the first output shaft 12 and the second output shaft 13 are connected to each other along the vertical axis L to rotate synchronously with respect to the body 11. In the present embodiment, the first output shaft 12 and the second output shaft 13 are substantially two portions of a driving shaft extending along the vertical axis L. However, in other variations, the first output shaft 12 and the second output shaft 13 may be two separate components that are separately manufactured but assembled together.

The balance unit 2 includes a lower housing member 21 for mounting the body 11, an upper housing member 22 mounted above the lower housing member 21 along the up-down axial direction D1, and a flywheel 23 mounted to the first output shaft 12 for rotation with the first output shaft 12 about the vertical axis L. The lower housing member 21 and the upper housing member 22 together define an internal space S for accommodating the flywheel 23.

The lower case member 21 has a mounting groove 211 centrally provided for the body 11 to be mounted, and a plurality of battery wells 212 annularly arranged around the mounting groove 211 and adapted for the battery to be mounted. The flywheel 23 has a support disc 231 mounted on the first output shaft 12, and a weight 232 engaged with the support disc 231. The tray 231 has a central portion 233 engaged with the first output shaft 12, an outer ring portion 234 radially spaced from the central portion 233 and surrounding the central portion 233, and a plurality of blades 235 connected between the central portion 233 and the outer ring portion 234. The outer ring 234 has a plurality of grooves 236 surrounding the central portion 233 and opening upward. The weight 232 has an annular base wall 237 disposed above the outer ring portion 234, and a plurality of annular walls 238 protruding downward from the base wall 237 and engaging with the grooves 236.

Referring to fig. 2 and 5, the walking unit 3 includes a gear set 31 engaged with the second output shaft 13, and two foot members 32 connected to opposite sides of the gear set 31 along the left-right axial direction D2. The gear set 31 has a steering gear 311 engaged with the second output shaft 13 and rotating around an axis extending along the left-right axial direction D2, two walking pivots 312 extending along the left-right axial direction D2 and being capable of being driven to rotate around their axes, four foot plates 313 respectively disposed at opposite ends of the walking pivots 312 along the left-right axial direction D2, and a plurality of transmission gears 314 connected between the steering gear 311 and the walking pivots 312 and driving the walking pivots 312. In this embodiment, the number of the walking pivots 312 is two, and the walking pivots 312 rotate synchronously and are spaced apart from each other along the front-rear axial direction D3. However, in other variations, the gear set 31 may have one or more than three walking pivots 312, but not limited thereto.

Each walking pivot 312 has a shaft body portion 315 extending along the left-right axial direction D2, and an annular tooth portion 316 surrounding the shaft body portion 315 and connected to the transmission gear 314. The foot plates 313 are fixed to opposite ends of the shaft body 315 in the left-right axial direction D2, respectively. Each foot tray 313 has a tray body 317 fixed to the respective walking pivot 312 for rotation with the respective walking pivot 312 and a mounting portion 318 connected to the tray body 317 and located eccentrically from the respective walking pivot 312 for mounting the respective foot member 32.

Referring to fig. 2, 5 and 6, each foot 32 has a main limb 321 pivotally connected to the corresponding mounting portion 318, and two branch limbs 322 extending from the main limb 321 to the front and the rear, respectively. Each limb 322 has a rope groove 323 extending along the front-rear axial direction D3 and opening downward. The cross-sectional profile of the rope groove 323 taken in a direction perpendicular to the front-rear axial direction D3 is substantially triangular and is adapted to allow the rope to slide to the highest position. When the walking pivot 312 rotates and the foot 32 changes position, the projected position of the rope groove 323 along the vertical axis direction D1 is always kept in the linear arrangement along the longitudinal axis direction D3.

Referring to fig. 1, 2 and 5, when the driving unit 1 drives the flywheel 23 to rotate through the first output shaft 12, the flywheel 23 generates a gyroscopic effect (gyroscopic effect) such that the rotation center is not easily deviated from the vertical axis L. That is, this embodiment can keep balance on the rope without falling down as long as the upright axis L is aligned with the rope. Since the rope groove 323 will slide the rope to the highest position by gravity, placing this embodiment on the rope does not require that the vertical axis L is perfectly aligned with the rope and some tolerance is tolerable. In addition, the mass of the flywheel 23 occupies a larger proportion than the total mass, and the obtained balance effect is also better. This is because the moment of inertia of the flywheel 23 rises with its own mass, making it less likely that the centre of rotation will deviate from the vertical axis L.

Further, if it is desired to increase the mass of the flywheel 23, a heavier metal may be used. However, plastic is an economical option in view of the cost involved. For this issue, the related solution proposed in this embodiment is as follows: since the flywheel 23 is composed of the supporting disc member 231 and the weight member 232, the supporting disc member 231 can be made of a relatively inexpensive plastic, and the weight member 232 can be made of a relatively heavy metal. Therefore, the balance effect and the consumed cost can be balanced, and a better balance effect can be obtained at lower cost. The selection of materials described herein is by way of example only and should not be construed in a limiting sense.

It is further noted that the configuration of the weight 232 is designed to provide the benefit that the annular wall 238 tends to distribute mass about the center of rotation rather than radially. Under the condition of the same total mass, the mass distribution mode can obtain higher rotational inertia so as to obtain better balance effect. Conversely, this embodiment reduces the material cost required by the design of the annular wall 238 for the same moment of inertia.

Furthermore, since the tray 231 has the fan blades 235, when the flywheel 23 rotates, the airflow induced by the fan blades 235 will flow through the main body 11 of the driving unit 1 and take away the waste heat generated by the operation of the main body 11, thereby generating a cooling effect.

Further, since the mounting portions 318 are provided eccentrically with respect to the respective walking pivots 312, when the walking pivots 312 rotate, the mounting portions 318 perform a circular motion about the respective walking pivots 312 in a plane perpendicular to the left-right axis direction D2. Therefore, when the position of the foot part 32 is changed in conjunction with the pivotally connected mounting part 318, the foot part 32 is always kept on the same plane and does not move in the left-right axis direction D2, and the projected position of the rope groove 323 in the up-down axis direction D1 is always kept in the alignment in the front-back axis direction D3. Thus, the present embodiment can simulate walking motion and move along the rope.

In summary, the rope toy of the present invention achieves the function of walking on the rope by the balance unit 1 keeping balance and the walking unit 3 simulating walking action, and the present invention can achieve the object of the present invention because the cost is low because it does not need to use a feedback signal system.
