The toys that use potential energy for power are creeping toys that imitate the movement of a caterpillar. However, such coiled spring-toys are limited in their movement in that the potential energy only provides a short service time and also the speed of the toys may not be adjustable. Therefore, what is desired is a creeping structure that can overcome the above-described problems.

FIG. 3 is a cross-sectional view taken along line III-III ofFIG. 1 . - Referring to
FIGS. 1-3 , acreeping structure 100 for use in a toy, e.g., a creeping toy, is illustrated. Thecreeping structure 100 includes afirst foot 110, asecond foot 120, afirst leg 132, asecond leg 134, and adriving device 136. Thefirst leg 132 is rotatably connected to thefirst foot 110. Thesecond leg 134 is rotatably connected to thesecond foot 120. Thefirst leg 132 and thesecond leg 134 are rotatably engaged with each other via thedriving device 136. - The
first foot 110 including ahousing 112 and afirst brake 116. - The
housing 112 is a hollow cylinder in shape, and includes, in this embodiment, acircular top surface 112 a, a cylindrical side-wall 112 b, aconvex bottom sheet 112 c, and afirst foot joint 112 d. Thetop surface 112 a is integrally formed with the side-wall 112 b. Thebottom sheet 112 c is made of flexible material, such as, rubber or silica gel, and is capped on the bottom of the side-wall 112 b. Thefirst foot joint 112 d includes twoparallel plates 1120 extending perpendicularly upward from thetop surface 112 a. The twoplates 1120 are spaced apart from each other, and each defines afirst pivot hole 112 e. - The
first brake 116 includes aretractable pole 1162. In this embodiment, thetop surface 112 a includes aninner surface 1122. Thetop surface 112 a also includes aprojection 128 substantially protruding perpendicularly from the center of theinner surface 1122. Theprojection 128 defines areceiving portion 1282. Thefirst brake 116 is received in thereceiving portion 1282. Theretractable pole 1162 is retractably connected to thebottom sheet 112 c to vary the air space between thebottom sheet 112 c and a creeping surface (not labeled) supporting the first andsecond feet retractable pole 1162 protrudes and pushes thebottom sheet 112 c to flatten, substantially fully abutting the creeping surface, thereby minimizing the space between thebottom sheet 112 c and the creeping surface. Theretractable pole 1162 is then retracted. Thebottom sheet 112 c returns to its normal convex shape. Because of the weight of thehousing 112 and thefirst leg 132, the outer edge of thebottom sheet 112 c forms an airtight seal with the creeping surface and thebottom sheet 112 c acts like a suction cup and grasps the creeping surface. When theretractable pole 1162 of thefirst brake 116 extends towards to thebottom sheet 112 c, thebottom sheet 112 c flattens and the suction force vanishes. - The
second foot 120 is similar with the structure of thefirst foot 110. - One end of the
first leg 132 defines asecond pivot hole 1322 aligned with the pair of thefirst pivot holes 112 e of thehousing 112. Thehousing 112 of thefirst foot 110 is rotatably connected tofirst leg 132 by inserting arotatable shaft 135 through the first andsecond pivot holes second leg 134 is rotatably connected to thesecond foot 120 using a similar structure. - The
driving device 136 includes afirst motor 1362 and a transmittinggear 1364. In this embodiment, thefirst motor 1362 is a rotary piezoelectric motor, but it is not limited to this embodiment. A rotor of thefirst motor 1362 includes adriving gear 1366 meshed with thetransmitting gear 1364. Thefirst motor 1362 is capable of changing the spinning direction of the rotor according to the direction of the electric current. In this embodiment, thefirst motor 1362 is installed in the end of thefirst leg 132 away from thefirst foot 110. The transmittinggear 1364 is installed on the end of thesecond leg 134 away from thesecond foot 120. Thefirst leg 132 is rotatably connected to thesecond leg 134 by thedriving gear 1366 of thefirst motor 1362 meshed to the transmittinggear 1364. - Alternatively, in other embodiments, the
first motor 1362 can be installed in thesecond leg 134, and thetransmitting gear 1364 can be installed on thefirst leg 132. - In this embodiment, the
creeping structure 100 further includes a controllingunit 140, the controllingunit 140 is installed in thefirst leg 132. It should be noted that, the controllingunit 140 can be also installed in thesecond leg 134. The controllingunit 140 is configured for driving thedriving device 136 and thefirst brake 116 synchronously, and changing the creeping speed of the first andsecond feet - In operation, firstly, the controlling
unit 140 controls theretractable pole 1162 of thefirst brake 116 of thefirst foot 110 to extend, pushing thebottom sheet 112 c. At the same time, the controllingunit 140 controls theretractable pole 1162 of thefirst brake 116 of thesecond foot 120 to retract. As a result, thefirst foot 110 is free from the creeping surface and thesecond foot 120 grasps the creeping surface. Meanwhile, the controllingunit 140 controls thedriving gear 1366 of thefirst motor 1362 to rotate counterclockwise to move thefirst foot 110 away from thesecond foot 120 along the creeping surface. As such, thecreeping structure 100 performs a creep step. Then, the controllingunit 140 controls theretractable pole 1162 of thesecond deriving device 116 of thesecond foot 120 to extend toward to thebottom sheet 112 c. At the same time, the controllingunit 140 controls theretractable pole 1162 of thefirst brake 116 of thefirst foot 110 to retract. As a result, thesecond foot 120 is free from the creeping surface and thefirst foot 110 is grasped by the creeping surface. Meanwhile, the controllingunit 140 controls thedriving gear 1366 of thefirst motor 1362 to rotate clockwise to make thesecond foot 120 creeping towards to thefirst foot 110 along the creeping surface. Repeating above steps, the creeping toy installed thecreeping structure 100 will be able to realize creeping. - The controlling
