Title:
TOY MECHANISM IMITATING A WALK
Document Type and Number:
WIPO Patent Application WO/2011/136668
Kind Code:
A1
Abstract:
The invention is a toy mechanism that makes the toy able to imitate the natural gait of bipedal creatures. Are known toys with the mechanism in the form of humans, animals, or different kinds of monsters, that can walk, but the driving force behind them is the electric motor for example with remote control or driving force is already rolled up,unrolling tin metal plate. The driving force of the toy is a hand that holds the toy vertically and moves it forward. Toy with a mechanism consistent with the description of the invention can be the form of variety of bipedal creatures as a human, animal or fairy tale character. The mechanism of the toy according to the description of the invention consists of core (1), wire (4) that passes through it, and a double crank (5) passing through the core (1), on a wire (4) are suspended inner arms (2) with fixed legs (7) to them. Holding the toy vertically we move it forward, one of the inner arms (2) with upright leg (7) that touches the ground is moving backward setting in rotary motion a double crank (5) that pivoting moves forward second inner arm (2). When one of the inner arms (2) with upright leg(7) that touches the ground is tilted far back, leg (7) bends and pushes up a rounded element (6), and this contributes to the continuation of a double crank (5) rotation that makes the second inner arm (2) moving forward and rounded element being part of external arm (3) goes down straightening the leg (7) that touches the ground and when pushing toy forward moves it back and then the course starts again.

1.Toy mechanism imitating a walk of two-legged creatures consisting of a core (1) ,wire (4) passing through hole (17) perpendicularly to the surface of core (1) and through hole (18) in the lower part of the core (1) passes a double crank (5), hole (17) is moved back in relation to the hole (18), on each side of one of two sides of core (1) parallelry to each other there is suspended on each of two ends of wire (4) one of two identical inner arms (2), to the surface of each of two inner arms (2) fits close parallelry one of two identical external arms (3), along each of two inner arms (2) extend slits (13) and along each of two external arms (3) extend other slits (15), each of two ends of the wire (4) passes through a hole (16), that is located in the upper part of each of two inner arms (2) and through slits (15), and through slits (13) passes one of two ends of double crank (5), that each of two ends also passes through the hole (14) located in the lower part of each of two external arms (3), to the bottom side of each of two inner arms (2) is fixed one of two legs (7).

2. Toy mechanism as set forth in claim 1 wherein the legs (7) and rounded elements (6) connect links (11) and legs (7) have hollow, a rounded element (6) is suitably rounded,

3. Toy mechanism as set forth in claim 1 wherein that to inner arms (2) are attached rails (8) and rails (9) , to the bottom of the legs (7) is glued rubber (10), and on double-crank (5) and wire (4) are fixed nuts (12)

Description:
TOY MECHANISM IMITATING A WALK

The subject of a patent is a mechanism that is mounted inside of toy. It can imitate the natural step of bipedal creatures. In the upper part of the core (1) there is a hole (17), and at the bottom is a second hole (18). Through the hole (17) perpendicularly to the surface of the core

(1) passes the wire (4.) and through the hole (18) perpendicularly to the surface of the core passes double crank (5). Each of two ends of the wire (4) passes through a hole (16) located in each of the two inner arms (2) and in this way the inner arms (2) are suspended . Inner arm

(2) with straightened leg touching the ground moves backward when pushing toy forward and moves forward when crank (5) rotates clockwise. The clockwise rotary motion of double crank (5) is caused by inner arm (2) that moves backward one after the other in turn , when leg (7) fixed to it touches the ground and later when rounded element (6) pushed up by tilted far back bending leg (7) goes up. Along inner arms (2) extend slits (13), through slits (13) pass and move along them ends of the rotating double-crank (5), each of the two ends of double crank (5) also passes through hole (14) in each of the two external arms ( 3), that move along and on inner arm (2) surface .Movement of the external arm (3) along and on inner arm (2) surface is caused by the rotation motion of the double crank (5) and wire (4) that passes through slits (15) extending along the each of the two external arms (3). To inner arms (2) are attached legs. (7) Legs (7) tilted far back , bend and push up the rounded element (6). Rounded element (6) when moving up contributes to clockwise motion of double-crank (5). Legs (7) and rounded elements (6) combine links (11). Legs (7) are lifted by links (11) that are attached to rounded elements (6). Legs (7) have hollow, and the rounded element (6) is suitably rounded (7) for leg being tilted back benting would push up rounded element (6) without encountering resistance from the rounded element. (6) Rail (9 ) prevents bending of the legs (7) to the front. To the bottom of the legs (7) is glued rubber (10), that improves adhesion to the surface.To inner arms (2) are fixed rails (8), that prevent rounded elements (6). from tilting to sides . Nuts (12) prevent displacement of the moving parts of the mechanism along the wire (4) and double-crank (5)
