DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

The present invention relates to a movable toy that is powered by a power source to move relative to or on a surface, such as a horizontal surface, an inclined surface, or a vertical wall. For example, the mobile toy may be powered by an internal battery or an external power source, moving from one place to another in a step-wise manner by means of the adhesive member. The adhesive member is movable relative to the surface between an engaged position and a disengaged position to advance through the surface in a particular direction.

Referring to fig. 1-6, an embodiment of a mobile toy 100 of the present invention is shown. In this embodiment, the movable toy 100 is configured as a reptile, particularly a lizard, having a body 102 and four movable legs 104, 106, 108, 110. In other embodiments, the movable toy 100 may be configured in the same shape as other living or inanimate objects. For example, the shape of the movable toy may be configured as an animal such as a cat, a dog, a tiger, or the like, an amphibian such as a frog and a lizard, or an insect such as a dragonfly, or the like, and an inanimate object. The mobile toy 100 is preferably configured as a legged creature, thereby mimicking the motion of a creature and making the toy more interesting.

The body 102 houses a motor unit (referenced 130 in fig. 7) for driving the two rotatable members 112, 114 in rotation about respective axes of rotation X, X', thereby advancing the legs 104, 106, 108, 110 in direction a. As shown in fig. 1-3, the rotatable members 112, 114 are spaced apart from one another, and two sets of adhesive members 120, 122 and 124, 126 are mounted on the sides of each rotatable member 112, 114, respectively, and in particular on opposite ends of each rotatable member 112, 114. In this embodiment, the rotatable members 112, 114 pass through the body 102. The above arrangement simulates the front and rear legs of a living being.

In alternative embodiments, the rotatable members of the movable toy may not pass through the body and may not be exposed to the surrounding environment through the body. The rotatable member and the adhesive member may be partially housed within the body.

Referring to fig. 1, the adhesion members 120, 122, 124, 126 are offset from the rotational axis X, X 'in opposite directions, i.e., are offset from the rotational axis X, X' by an angle in opposite directions. In other words, the adhering members 120, 122, 124, 126 do not rotate about the same rotational axis X, X' as the rotatable members 112, 114. This facilitates movable toy 100 advancing more smoothly across a surface in larger steps.

The rotatable members 112, 114 are driven by the motor unit 130 to rotate substantially simultaneously in the same direction. Preferably, the rotation drives the respective adhesive members 120, 122, 124, 126 to move between the engaged and disengaged positions in a out-of-phase manner. That is, the adhering member on the same rotatable member does not do the same action to engage or disengage with the surface. For example, when left adhesive member 120 is moved from the engaged position to the disengaged position, right adhesive member 122 is moved from the disengaged position to the engaged position relative to the surface. The engaged left adhesive member 120 will act as a fulcrum for the movement of the disengaged adhesive member 122 and vice versa. Thus, movable toy 100 is caused to produce a climbing effect heading in direction A.

In this embodiment with two or more rotatable members 112, 114, the diagonally located adhesive members are in the same phase, e.g., adhesive members 120 and 126, and adhesive members 122 and 124, respectively, are in the same phase. This will contribute to a smoother movement. As shown in fig. 2 and 3, the legs 106, 108 carrying the adhesive members 122, 124 are in phase, i.e., both are in the disengaged position, while the legs 104, 110 carrying the adhesive members 120, 126 are in phase, i.e., both are in the engaged position. Fig. 5 and 6 are reversed.

By using the adhesive members 120, 122, 124, 126, the movable toy 100 can be adhered to a surface, particularly a vertical wall. Each adhesive member 120, 122, 124, 126 has a portion that interacts with the surface, causing itself to adhere to the surface when a force is applied to the surface by the adhesive member (i.e., in the engaged position). The legs can also be released from the surface when pulled away from the surface with a force (e.g., a lifting force). The rotatable members 112, 114 rotate to apply the required force against the surface to the respective adhesive members 120, 122, 124, 126.

In this embodiment, the adhesive members 120, 122, 124, 126 are suction cups made of a deformable plastic material. The suction cups can be compressed to create a vacuum that holds the legs in place and stretched by the lifting force to release. The rotatable members 112, 114 transmit sufficient force to adhere some suction cups to the wall and simultaneously release the remaining suction cups from the wall.

It should be understood that passive suction cups are particularly suitable for the present invention. Since the present invention does not require external energy or units to promote adhesion adsorption, a large amount of energy is saved. Furthermore, passive suction cups help to avoid undesirable accidents caused by active vacuum generators while a child plays with a toy, and the present invention is therefore also advantageous. Other adhesive means/materials (e.g., velcro) and suction strips (e.g., micro-suction strips) may be used in addition to or in place of the suction cups. Different combinations of adhesive members may also be used in a single movable toy. In an alternative embodiment, weak magnets may also be used in the toy.

Referring to fig. 7, an example of an internal motor-gear arrangement of mobile toy 100 is shown. The motor unit 130 is powered by a power source (not shown). The power source may include an internal battery or a battery compartment for housing a battery. In one embodiment, the batteries may be rechargeable and may be charged by an external power source through an electrical outlet provided on the main body 102. The use of a rechargeable power source is advantageous because it can be reused and avoids the need to replace a new battery.

In operation, the motor unit 130 drives the drive shaft 132 to rotate. The drive shaft 132 is connected to a first gear train 134 and a second gear train 136, respectively. In particular, the drive shaft 132 is located between a first gear train 134 and a second gear train 136 to simultaneously drive both gear trains 134, 136. As the drive shaft 132 rotates, the gears in each gear train 134, 136 are driven to rotate at a reduced speed. Each gear train 134, 136 may include a different number of gears to establish a desired gear ratio. The final gear of the first and second gear trains 134, 136 is the rotatable member 112, 114 having outwardly extending projections 204, 206 for mounting the adhesive member.

Referring to fig. 8, an embodiment of rotatable member 112 of movable toy 100 is provided. The rotatable member 112 has a gear plate 202 coupled to adjacent gears in the first gear train 134, and first and second protrusions 204 and 206 inclined at an angle from the rotational axis X in opposite directions of the gear plate 202. That is, the major axes of the first and second protrusions 204, 206 are not parallel to the rotational axis X of the rotatable member 112. Thus, for better performance, the respective adhesive members 120, 122 mounted thereon are offset from the axis of rotation X in opposite positions. The rotatable member 114 is generally identical to the rotatable member 112, but is preferably disposed in an out-of-phase manner with respect to the rotatable member 112.

Fig. 9 illustrates another embodiment of a rotatable member 210 that may be used in a movable toy according to the present invention. The rotatable member 210 has a gear plate 212 coupled to adjacent gears in the gear train, and first and second projections 214 and 216 extending eccentrically and laterally in opposite directions from the gear plate 212. The first and second protrusions 214, 216 carry the adhesive members 120, 122 through the legs 104, 106, respectively. Thus, when the rotatable member 210 is driven to rotate, the adhesive members 120, 122 carried by the first and second protrusions 214 and 214 will move in different phases.

It will be appreciated that the legs and the adhesive member may be the same components as described above, and that various configurations of rotatable members may be employed to achieve the desired effect, in accordance with the disclosure herein.

Referring again to fig. 7, in embodiments herein, the second gear train 136 has an additional gear 138 as compared to the first gear train 134. The additional gear 138 functions as an idler gear to transfer motion without changing direction or gear ratio such that the final gear (i.e., the rotatable members 112, 114) advances across the surface in the same direction of rotation (e.g., clockwise). The provision of an idler gear is important in embodiments where a single drive shaft 132 is provided to drive more than one gear train for more than one rotatable member. This is also advantageous because the movable toy can be manufactured in a relatively small and compact size.

It will be appreciated that the mobile toy of the present invention is particularly suited as a climbing toy that can climb on inclined or substantially vertical surfaces without the use of substantial traction. The movable toy is configured to mimic the motion of a living being with which users (especially children) may find fun to play and with which they may also learn how different living beings walk. And thus may be used for educational purposes.

It should also be understood that the movable toy of the present invention may also include one or more additional movable members that are free to rotate or move on the surface in contact. In an example embodiment, the movable toy has one rotatable member, and two adhesive members are disposed on the sides of the rotatable member. The movable toy also has an additional movable member that is free to rotate to support the motion of the toy on a surface (e.g., a substantially horizontal surface). The movable member is not adhesive and can serve as one of the fulcrums for moving the adhesive member.

In addition to the present invention, the mobile toy may include additional electronics for various purposes, such as light bulbs, LED lights, speakers and/or microcontrollers. These items may help to attract the user's attention, making it more interesting.

It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.

Any reference to prior art contained herein is not to be taken as an admission that the information is common general knowledge, unless otherwise indicated.
