Claims
- 1. A hair drying apparatus for drying hair on a person's head comprising:
- an electric motor;
- a plurality of hair drying lamps for drying the hair;
- arms for supporting said lamps;
- a mechanism for transmitting motion from said motor to said arms and said lamps, said mechanism including
- a head assembly having a first support means, a grooved pulley journalled in said first support means, second support means, a slide means supported by said second support means and lying within said groove, said first support means being pivotal with respect to said second support means,
- a neck assembly connected to said head assembly, said neck assembly including a rocker arm rigidly fixed to said second support means and a cam rigidly fixed to said first support means; and
- base means for supporting the rocker arm for pivotal movement about an axis which is transverse to the rocker arm, said base means having a surface rigidly fixed thereto for contacting said cam, said motor causing said grooved pulley to rotate whereby said mechanism moves said arms and said lamps around the head and hair to direct the lamps toward different areas of the hair on the head.
- 2. A hair drying apparatus as claimed in claim 1 wherein said first support means comprises a U-shaped member having an inner space and a hole therein, said grooved pulley having a pin, said pulley being located in said space with said pin being journalled in said hole and projecting outwardly therefrom along a first axis, said second support means comprising a fork having two downwardly extending portions, said slide means comprising sliders connected to each of said downwardly extending portions of the fork, said rocker arm having outwardly projecting portions connected to the ends of said downwardly extending portions of the fork whereby upon rotation of said grooved pulley and said pin by said motor, said sliders slide within said groove and due to the inclination of said groove, said motor, pin, arms and lamps oscillate in planes which are normal to said rocker arm.
- 3. A hair drying apparatus as claimed in claim 1, wherein said base means comprises a transverse arm, said surface for contacting said cam being on said transverse arm; said motion by said motor being translated by said grooved pulley and slide means into pivotal motion of said first support means and the cam relative to said second support means, said rocker arm being pivotally connected to said base means whereby, when said cam is pivoted, said cam causes said rocker arm to oscillate about its pivotal connection with said base means.
- 4. A hair dryer apparatus as claimed in claim 1 wherein said base means has an upper face and a lower face, said surface for contacting said cam being on said upper face and a cam lever being connected to said lower face thereof, said lever being eccentrically and pivotably connected to said lower face to provide for lifting or lowering of said rocker arm.
- 5. A hair drying apparatus as claimed in claim 2, wherein said base means further comprises a transverse arm along a second axis, said surface for contacting said cam being on said transverse arm, said motion by said motor being translated by said grooved pulley and slider into pivotal motion of said first support means and cam relative to said second support means, said rocker arm being pivotally connected to said base to pivot about a third axis whereby pivotal movement of the cam produces oscillating movement of said rocker arm about said third axis.
- 6. A hair drying apparatus as claimed in claim 5, wherein said first and said third axes fall within a common plane and said second axis is orthogonal to said first and third axes.
- 7. A hair dryer apparatus as claimed in claim 5 wherein said base means has an upper face and a lower face, said transverse arm being on said upper face, and a cam lever being eccentrically and pivotably connected to said lower face to provide for lifting or lowering of said rocker arm.
- 8. Hair drier apparatus for drying the hair of a user, comprising,
- a plurality of arms,
- hair drying lamps mounted on said arms,
- first means for rotating said arms about a first axis, said first means including a sheave engaged with a slider, said sheave being rotatable with respect to said slider,
- second means for changing the inclination of the first axis, said second means including a cam surface engaged with a stationary member,
- said second means being operable simultaneously with the first means to move the lamps around the user's head in an arcuate path which is not located in a flat plane.
- 9. Hair drier apparatus according to claim 8 wherein the sheave is rotatable about a rotational axis which is fixed with respect to the arms, said sheave lying in a plane which is inclined relative to said rotational axis.
- 10. Hair drier apparatus according to claim 8 comprising,
- a base having a cam engaging surface thereon,
- a first assembly of rigidly interconnected members including a rocker arm, a yoke, and said slider mounted on the yoke, said rocker arm being aligned with and nonrotatable with respect to said first axis, said rocker arm being connected to the base for pivotal movement about a second axis which is transverse to said first axis,
- a second assembly of rigidly interconnected members including a shaft which is aligned with and rotatable with respect to said first axis, bearing means for supporting the sheave at one end of the second arm for rotation about a third axis which is transverse to the first axis, said sheave being inclined with respect to said third axis so that rotation of the sheave will act on said slider to rotate the shaft relative to the rocker arm, said cam being affixed to said shaft and being in contact with said stationary member so that rotation of said shaft will turn said cam to change the inclination of the first axis.
