Abstract
A portable electrical appliance such as an electric dry shaver wherein all the operative elements are mounted on a shroud support assembly for removal as an operative unit from the shaver casing. The support means further include a structural arrangement for permitting the vibratory motor of the appliance to be suspended clear of the casing sidewalls to allow for slight pivotal movement thereof during operation to absorb and reduce vibrations in operation of the appliance.
Claims10
In a portable electrical appliance,
- a. a casing,
- b. a shroud assembly disposed adjacent one end of the casing,
- c. a motor assembly having a stator and a pivotally mounted armature for driving an output means,
- d. means suspending the motor assembly from the shroud assembly, said suspending means providing a pivot for the motor assembly, the motor assembly moves about the pivot in an arcuate path upon energization of the motor assembly,
- e. a block assembly disposed adjacent the other end of the casing and secured thereto,
- f. means interconnecting the block assembly to the shroud assembly, and
- g. dampening means engaging said interconnecting means to dampen said arcuate movement of the motor assembly in the operation of the motor assembly.
A support assembly for the operative elements of an electric dry shaver arranged within an enclosure casing comprising,
- a. a shroud assembly seated on said enclosure and from which shroud assembly is suspended a vibratory motor,
- b. a cutter head assembly and drive means therefor supported by said shroud assembly,
- c. a support block spaced from said shroud assembly and arranged at the base of the enclosure,
- d. means interconnecting said shroud assembly to said support block and including portions for positioning one end of the motor,
- e. means for releasably securing said support block to said casing,
- f. said shroud assembly including a pair of mated sections between which is held the opposite end of the motor,
- g. said means interconnecting said shroud assembly to said support block including a pair of strap members having opposite ends detachably secured to said support block and to said shroud assembly,
- h. said straps are provided with oversized openings in which are arranged the opposite ends of a shaft within the stator of said vibratory motor, and
- i. resilient material is provided about the ends of said shaft to absorb vibrations in operation of the motor.
