DESCRIPTION OF THE PREFERRED EMBODIMENT
The accompanying drawings depicted various embodiments of a wall descending toy along with various embodiments of an actuating wheel. Although specific examples are presented to illustrate the invention, it should be appreciated that this invention extends to other configurations.
Referring to FIG. 1, there is depicted a wall descending toy with moveable parts in the form of a turtle. The toy includes a housing 1 holding an actuating wheel 2, a sticky wheel 3, moveable parts 4 and a mechanical link 5. The sticky wheel 3 has an undulating sticky peripheral surface which allows the toy to travel down a vertical or steeply inclined surface. Suitable materials for the sticky surface 3 include a sticky gelatinous composition, such as a melt blend admixture of poly (styrene-ethylene-butylene-styrene) triblock copolymer and plasticising oils which form bonds with the wall surface to allow the toy to travel on a vertical or steeply inclined surface. The actuating wheel 2 is rotatably mounted with the housing 1 for rotating with the transfer of the toy on the surface. The actuating wheel 2 is engaged with the moveable parts 4 by one or more mechanical links 5. The moveable parts 4 are moveably engaged with the mechanical links 5 and pivotally engaged with the housing 1 at a pivot point 19. The mechanical links 5 is a thin strip made from a copolymer of Acrylonitile, Butadiene and Styrene. There can be one or more mechanical links 5 within a wall descending toy and each mechanical links 5 can be connected to one or more moveable parts 4.
FIGS. 2 and 3 depicted a first embodiment of the actuating wheel 2 having a rotary shaft 7 along which is a cylindrical body 8. The cylindrical body 8 has first and second end with rims 9 for rotating with the transfer of the toy on the surface. A circumferential groove 10 is disposed on the cylindrical body 8. The groove 10 provides an engagement point between the actuating wheel 2 and the mechanical link 5.
FIGS. 4 and 5 shows a second embodiment of the actuating wheel 2. This wheel also has a rotary shaft 7 along which is a cylindrical body 8. The cylindrical body 8 has first and second end with rims 9 for rotating with the transfer of the toy. Pegs 11 are disposed on the rims 9 at the first end of the cylindrical body 8. These pegs 11 become the engagement points between the actuating wheel 2 and the mechanical links 5.
As shown in FIGS. 6 and 7, the third embodiment of the actuating wheel 2 is a combination of the two actuating wheels as shown in FIGS. 2, 3, 4 and 5. The actuating wheel 2 of FIGS. 6 and 7 has a rotary shaft 7 along which is a cylindrical body 8. The cylindrical body 8 has first and second end with rims 9 for rotating with the transfer of the toy. A, circumferential groove 10 is provided at the cylindrical body 8 with pegs 11 disposed on the rims 9 at the first end of the cylindrical body 8. The groove 10 and the pegs 11 allow two mechanical links 5 to be engaged with the actuating wheel 2. Each mechanical link 5 is engaged with a different set of moveable parts 4 to bring about different movements in respective moveable parts 4 at the one time.
The actuating wheel 2 is made of ductile and resilient material selected from the group consisting Polyvinyl Chloride (PVC) and Thermoplastic Rubber (TPR). These materials are most suitable as they are of resilient nature and present a good adhesion surface. The size of the actuating wheel 2 is similar to that of the sticky wheel 3 and the diameter of the actuating wheel 2 should not be bigger or smaller than 20% of the diameter of the sticky wheel 3.
The movement of the moveable parts 4 is controlled by the configuration of the actuating wheel 2. Referring to FIGS. 8, 9 and 10 there is depicted a first embodiment of the wall descending toy with moveable parts in the form of a wall descending cup noodle with a pair of moveable chopsticks 12. The cup noodle includes the sticky wheel 3 and the actuating wheel 2 having a rotary shaft 7 along which is a substantially cylindrical body 8. The cylindrical body 8 has first and second end with rims 9 for supporting the actuating wheel 2 on the surface. A circumferential groove 10 is disposed on the cylindrical body 8 as shown in FIGS. 2 and 3. The mechanical links 5 has a protrusion 16 for engaging with the groove 10. When the cup noodle travels along a vertical wall, the rotation of the actuating wheel 2 actuates the reciprocal sideway movements of the mechanical links 5, which in turn guides the chopsticks 12 to pivot about a pivot point 19. In this way, the rotation of the actuation wheel 2 brings about the angular reciprocal motion of the chopsticks 12.
Referring to FIGS. 11 and 12, there is depicted a second embodiment of the wall descending toy in the form of a racing horse. The racing horse has three moveable parts 13, 14, and 15. These moveable parts 13, 14 and 15 are engaged with the actuating wheel 2 through a mechanical link 5. The actuating wheel 2 has a rotary shaft 7 along which is a cylindrical body 8 having first and second end with rims 9 for supporting the actuating wheel on the surface. Also, pegs 11 are disposed on the rims 9 at the first end of the cylindrical body 8 as shown in FIGS. 4 and 5. The clogs become the engagement points between the actuating wheel 2 and the protrusion 16 of the mechanical links 5. When the racing horse travels along a vertical surface, the actuating wheel 2 rotates and the first peg 11 will remain engaged with the protrusion 16 until it moves to a releasing point where the protrusion 16 is released to the next pegs 11(a) and bring about a reciprocal sideway movement of the mechanical links 5. The sideway movement of the mechanical links 5 will force the moveable parts 13, 14 and 15 to pivot over the pivot points 19 and bring about an angular reciprocal motion.
Referring to FIGS. 13, 14 and 15, it shows a third embodiment of the wall descending toy in the form of a cockroach with moveable head 17 and legs 18. The cockroach includes an actuating wheel 2 having a rotary shaft 7 along which is a cylindrical body 8. The first and second ends of the cylindrical body have rims 9 rotating with the conveyance of the toy. An circumferential groove 10 is provided at the cylindrical body 8 with pegs 11 disposed on the rims 9 at the first end of the cylindrical body 8, as shown in FIGS. 6 and 7. The head 17 and the legs 18 are connected to the actuating wheel 2 separately by two mechanical links 5. The head 17 is connected to the pegs 11 of the actuating wheel 2 and the legs 18 are connected to the groove 10. The mechanical links 5 have protrusions 16 for engaging with the groove 10 and the pegs 11 and one of the mechanical links 5 is integrally formed with the moveable parts, namely the legs 18. When the cockroach travels along a vertical surface, the rotation of the actuating wheel 2 actuates a reciprocal sideway movement of the mechanical links 5 which forces the head 17 and legs 18 to pivot over the pivot points 19 which bring about an angular reciprocal motion.
It should be appreciated that modifications and alterations obvious to those skilled in the art are not to be considered as beyond the scope of the present invention. For example, in the preferred embodiments there is an actuating wheel engaged with the moveable parts to bring about their movement and a sticky wheel to allow wall walking. In an alternative embodiment, there can be a duel functional wheel which is both a sticky wheel and an actuating wheel.
The preferred embodiment has at most two mechanical links with specific shapes. In an alternative embodiment, there can be more than two mechanical links with various shapes to serve its purpose.
The preferred embodiment has a pivot point for engaging the moveable parts to the mechanical link. In an alternative embodiment, there need not be a pivot point.
The preferred embodiment there is two wheels, a sticky wheel and an actuating wheel. In an alternative embodiment, there can be more than two wheels.
