Definitions

  • ABSTRACT Toys that simulate power tools, including pull-string motors that drive mechanisms which vibrate the housing and make noises.
  • One toy has a housing representing an electric drill and a rotatable shaft in the shape of a drill chuck and drill.
  • An eccentric weight is mounted in the chuck to vibrate the drill when the output shaft is rapidly rotated.
  • Common power driven devices such as electric drills and electric mixers are often very interesting to children not only because they are used only by adults, but also because they have rapid movements and make noise.
  • Toys that simulate such articles can be made especially interesting by including apparatus for making noises and movements appropriate to the simulated tool and even in an exaggerated amount.
  • a toy simulating real life power driven equipment which simulates movements and noises created by the real life equipment as well as having a similar appearance.
  • the toy includes a pullstring motor that drives an output shaft with an eccentric Weight thereon that vibrates the toy housing.
  • a multi-tooth wheel fixed to the shaft is engaged by a leaf spring that extends to an acoustical amplifier for making noise as the shaft rotates and the toy housing vibrates.
  • a manually controlled trigger can engage a toothead wheel on the output shaft to prevent shaft rotation until a child operates atrigger or the like that simulates the switch on the real life tool.
  • the output shaft has an outer portion that has the shape of a drill chuck and drill bit.
  • a weight is mounted in the drill chuck at one side of the axis of rotation to vibrate the drill. The location of the weight in the chuck results in wobbling of the drill bit that simulates movements of real drills due to torques often encountered in drilling.
  • Another toy represents an electric mixer wherein at least one of the mixing blades is thicker than the others to create vibrations when the blades rotate.
  • Still another toy represents a chain saw, and includes an enclosed shaft carrying a large eccentric weight to vibrate the housing. The pull-string of the chain saw motor extends with a rearward directional component to simulate the starting cord on a real gasoline engine chain saw.
  • Another toy represents a helicopter with an unbalanced rotor for vibrating the helicopter housing.
  • Yet another toy represents a sewing machine with a pressure foot and needle that oscillate up and down and which hit the housing on every downstroke to generate noise.

  • FIG. 11 is a perspective view of a toy sewing machine constructed in accordance with a still further embodiment of the invention.
  • FIG. 12 is a partial, enlarged perspective view of the sewing machine of FIG. 11, showing the operating mechanism thereof.
  • FIGS. 1-4 illustrate a toy drill 10 which includes a housing 12 representing that of a common electric drill, and an output shaft 14.
  • the output shaft 14 projects through a hole 16 in housing 12, and has an outer portion 18 in the shape ofa drill chuck 20 with a drill 22 therein.
  • a motor 23 mounted within the housing is coupled to the output shaft 14 to rapidly rotate it.
  • the motor is of the pull-string type which is operated by pulling and releasing a'string 24.
  • a child can operate the drill by pulling a knob 26 attached to the string 24 to wind the motor 23.
  • the child grasps a handle 28 formed on the housing, and places his index finger around a trigger switch or trigger 30.
  • the trigger releases the shaft 14 to permit it to rapidly rotate.
  • the tool provides a realistic, if not exaggerated, simulation of an operating drill.
  • the drill chuck 20 and drill 22 are seen to rapidly rotate while large vibrations can be felt and considerable realistic noise is heard.
  • Vibrations of the toy are produced by a weight 32 that is mounted in the drill chuck 20 near the radially outer portion thereof.
  • the chuck 20 provides a good mounting location for the eccentric weight 32 because the chuck is an enlarged portion of the output shaft that must be provided anyway for a realistic appearance.
  • vibrations induced at the location of the chuck 20 provide an especially realistic movement, because the weight 32 at an overhanging shaft location urges the output shaft 14 to rapidly wobble as it rotates.
  • the drill 22 and chuck 20 therefore appear to rapidly vibrate in a manner simulating vibrations resulting from operation of a real electric drill.
  • a realistic noise is generated by a multitoothed wheel 36 which is fixed to the output shaft 14.
  • a resilient member 38 of a material such as spring steel, has an outer end in the path of the teeth 40, so that the resilient member is rapidly vibrated when the shaft rotates.
  • the resilient member 38 has an opposite end fixed to a thin and wide-area diaphragm or speaker 42 which vibrates a considerable volume of air so that a loud I noise is created.
  • Holes 44 are formed in the housing to structed of a material which is easily formed by injection molding, such as polyethylene foam. This material tends to dampen vibrations, and the separate speaker 42 is therefore utilized to amplify vibrations instead of attaching an end of the resilient member 38 to the housing.
  • the trigger 30, which can start and stop the tool, has an arm 46 which engages the multi-toothed wheel 36 to normally prevent output shaft rotation.
  • the trigger 30, which is pivotably mounted at 48 on the housing, has a spring'arm 50 that bears against a flange 52 of the housing. The trigger can be pivoted to the position 30a when a child operates the trigger, to disengage the arm 46 from the multi-toothed wheel and permit the motor 23 to rapidly rotate the output shaft.
  • the motor 23 which drives the output shaft includes a string drum 54 on which an inner end of the pullstring 24 is mounted.
  • the drum 54 is fixed to a motor shaft 56 that is rotatably mounted on a motor frame 58.
  • a coil spring 60 which has opposite ends respectively fixed to the shaft 56 and to the frame 58, is wound when the pull-string 24 is pulled. The wound spring then urges the shaft 56 to rotate in an opposite direction to rewind the string on the drum 54.
  • the motor shaft 56 is coupled to the output shaft 14 through a motor gear 62 fixed to the motor shaft 56, an idler gear assembly including an idler pinion 64 and idler gear 66 that are both fixed to an idler shaft 68, and an output gear 70 that is fixed to the output shaft 14. If all of the gears of this gear train were constantly engaged, then the output shaft 14 would be rotated when the pull-string 24 were pulled. This would be undesirable because it would make pulling of the string more difficult and because the trigger 30 would then have to be held depressed while the string were pulled. To prevent constant engagement of the gears, the motor housing 58 is provided with a pair of slots 72 (FIG. 3) which the idler shaft 68 can slide along. This permits the idler shaft 68 to slide from a first position wherein the idler gear 66 is disengaged with the output gear 70, to a second position wherein the idler gear at 66a (FIG. 4) is engaged with the output gear 70.
  • a pair of slots 72 FIG. 3
  • the slot 72 which receives the idler shaft 68 is oriented along an imaginary line 74 which extends along a radius to the axis of rotation 32 of the output gear 70 and circumferentially about the axis 76 of the motor gear 62. Accordingly, the idler pinion 64 is always engaged with the motor gear 62, but the idler gear 66 can move into and out of engagement with the output gear 70.
  • the direction in which the pull-string 24 is wound about the pulley 54 is chosen so that, when the pullstring is pulled, the motor gear 62 rotates in the direction of arrow 78.
  • the teeth of motor gear 62 then move past the idler pinion in the direction of arrow 80 to urge the idler gear 64 away from the drive shaft gear 70.
  • the coil spring 60 rotates the motor gear 62 in the direction of arrow 82, which results in the teeth of the motor gear 62 moving past the idler pinion 64 in the direction of arrow 84.
  • the idler shaft 68 This causes the idler shaft 68 to shift its position so that the idler gear 66 engages the drive shaft pinion 70 to rotate the drive shaft-Thus, the motor is automatically disengaged and engaged with the output shaft 14 to facilitate motor winding.
  • the idler shaft and gear assembly therefore acts not only as a speed increasing gear train but also as a direction sensitive clutch.
  • FIGS. 5 and 6 illustrate a toy chain saw which simulates a real chain saw not only in appearance, but in the generation of realistic noises and the creation of realistic vibrations.
  • the toy includes a housing 102 5 largely simulating that of a chain saw, including a forwardly extending simulated chain 104 and a rearwardly extending handle 106.
  • a pull-string motor 108 is mounted in the housing to drive a shaft 110.
  • a large weight 111 is mounted eccentrically on the shaft to vibrate the housing when the shaft rapidly rotates.
  • a toothed wheel 112 is also mounted on the shaft, and a resilient member 114 that extends to a speaker 118 engages the toothed wheel to generate noise.
  • a trigger 120 pivotably mounted on the housing at 122, has a 5 brake arm 124 normally engaging a projection on shaft 110 normal thereto. This prevents rotation of the output shaft.
  • the output shaft is freed for rotation by the motor 108.
  • the housing is provided with an upstanding handle of a type which is often found on chain saws.
  • the pull-string 132 of the motor extends with a rearward directional component from the location 134 where it passes through the housing. This is a direction simulating the direction in which a starting cord generally extends from the gasoline engine of a chain saw.
  • a child can wind the motor by pulling on a knob 136 attached to pull string 132 while holding the handle 130 of the chain saw, in a manner simulating the starting of the gasoline engine of a real chain saw. The child may then hold the top handle 130 in one hand and the rearward handle 106 in his other hand and squeeze the trigger 120 to cause the chain saw to operate. The toy chain saw then vibrates and makes considerable noise.
  • FIGS. 7-9 illustrate a toy electric mixer 140 which simulates a real mixer.
  • the toy mixer 140 includes a housing 142 representing an electric mixer housing, and an output shaft 144 projecting through the housing.
  • the output shaft 144 has an inner portion within the housing, which is motor driven, and an outer portion representing multiple mixing blades. As illustrated in FIG. 8, some of the blades 146, 148 are of greater mass than other blades 150, 152. These heavier blades 146, 148 are concentrated on one side of the output shaft to form an eccentric weight that unbalances the shaft.
  • the mixer includes a motor 154 similar to that of the motor 23 in FIG. 1, with a drawstring 156 extending through the housing. The motor drives an output gear 158 on the output shaft to rotate it.
  • the upper end of the output shaft has a single tooth 160 extending therefrom which can be engaged to prevent output shaft rotation.
  • a manually operated switch button 162 is slideably mounted on the housing and has a toothed wheel 164 at its lower end for engaging the tooth 160 of the output shaft.
  • the button 162 is depressed against the biasing of a pair of leaf springs 166, the teeth at 164 move down and out of engagement with the tooth 160 of the shaft to permit output 60 which has an end portion biased against a multishaft rotation.
  • Noise is made by a resilient member 168' blades of lightweight material, and also includes a weight 198 in one of the rotors for unbalancing the output member to make the craft vibrate when the output member rotates.
  • the toy also includes a multi-toothed wheel 200'and a leaf spring 202 for engaging the teeth of the wheel to create noise.
  • FIGS. 11 and 12 illustrate a toy sewing machine 210 which produces movements, vibrations, and noise simulating a real sewing machine.
  • the sewing machine includes a housing 212 with an upper housing portion 214, a lower housing portion 216, and a column 218 joining the upper and lower housing portions.
  • a reciprocal member 220 is moveably mounted in the housing and has a lower portion representing a pressure foot 222 and a needle 224, the foot 222 and needle 224 being integral.
  • the reciprocal member 220 has a large bearing hole 226 which receives an eccentric portion 2280f a drive shaft 230.
  • the drive shaft 230 is driven by a pull-string member 232 which is of the type shown at 23 in FIG. 1 and which is mounted in the housing.
  • Motor 232 has a pull-string 234 extending through the column portion 218 of the housing.
  • the eccentric portion 228 moves the middle portion of the reciprocal member 220 in a circle. This causes the pressure foot 222 and needle 224 to move, and some of the movement is in an up and down direction.
  • the reciprocal assembly 220 moves down low enough so that it strikes the lower portion 216 of the housing to create a tapping sound.
  • the lower end or tip 236 of the needle 224 is the portion that actually contacts the lower housing portion 216, and a relatively sharp sound is made.
  • the rapid movement of the reciprocal member 220 creates vibrations, and these vibrations and the tapping sound simulate the operation of a real sewing machine.
