Abstract

Abstract A hair dryer that may be collapsed for carrying and erecting for operation, including a base assembly, a rigid tiltable hood assembly to be positioned about the head of the user for distributing heated air to the head and a strut hinged at both ends to the hair dryer between the hood assembly and base assembly one end of the strut being connected to the hood assembly. A push-rod member pivotally movable about two points and maintained under compression force cooperates with the hinged strut to apply supporting force to the hood assembly when the hair dryer is in the erected position. In the carrying position the push-rod is out of compression so that the hair dryer may be collapsed.

Claim 4
Dependent Claim 200 words
A hair dryer comprising: a. a base assembly housing means for producing a flow of heated air, b. a rigid hood assembly arranged to be positioned about the head of the user and having means for distributing heated air to the head, c. air conducting means for directing heated air from said producing means to said hood assembly, said air conducting means including a hollow air duct assembly hingedly secured at both ends to the hair dryer, one end of which is connected to the hood assembly, d. means including the air duct assembly for lowering said hood assembly relative to said base assembly for carrying the hair dryer and for raising the hood to an elevated position relative to the base assembly to an operative position, and e. a push-rod member being pivotally movable about two points and maintained under compression force when the hair dryer is in the operative position and out of compression when the hair dryer is in the carrying position, said push-rod member cooperating with said air duct assembly to apply supporting force to said hood assembly whereby the hood assembly may be rotated about its center of gravity to a desired angle of tilt.
Claim 5
Dependent Claim 200 words
A hair dryer comprising: a. a base assembly housing means for producing a flow of heated air, b. a rigid hood assembly arranged to be positioned about the head of the user and having means for distributing heated air to the head, c. air conducting means for directing heated air from said producing means to said hood assembly, said air conducting means including a hollow air duct assembly hingedly secured at both ends to the hair dryer, one end of which is connected to the hood assembly, d. means including the air duct assembly for lowering said hood assembly relative to said base assembly for carrying the hair dryer and for raising the hood to an elevated position relative to the base assembly to an operative position, and e. a push-rod member being pivotally movable about two points and maintained under compression force when the hair dryer is in the operative position and out of compression when the hair dryer is in the carrying position, said push-rod member cooperating with said air duct assembly to apply supporting force to said hood assembly whereby the hood assembly may be rotated about its center of gravity to a desired angle of tilt.
Claim 6
Dependent Claim 153 words
A hair dryer comprising: a. a base assembly housing means for producing a flow of heated air, b. a rigid hood assembly arranged to be positioned about the head of the user and having means for distributing heated air to the head, c. heated air conducting means for directing heated air from said producing means to said hood assembly including three foldably hinged hollow air ducts comprising a lower duct, a upper duct and a hood duct hinged to said hood assembly, and d. an elongated push-rod member, said push-rod member extending through the middle air duct and having one end thereof pivotally attached to the hood duct and the opposite end removably pivotally mounted within the lower duct, said push-rod member cooperating with said air ducts to apply supporting force to said hood assembly whereby the hood assembly may be rotated about its center of gravity to a desired angle of tilt.
Claim 7
Dependent Claim 153 words
A hair dryer comprising: a. a base assembly housing means for producing a flow of heated air, b. a rigid hood assembly arranged to be positioned about the head of the user and having means for distributing heated air to the head, c. heated air conducting means for directing heated air from said producing means to said hood assembly including three foldably hinged hollow air ducts comprising a lower duct, a upper duct and a hood duct hinged to said hood assembly, and d. an elongated push-rod member, said push-rod member extending through the middle air duct and having one end thereof pivotally attached to the hood duct and the opposite end removably pivotally mounted within the lower duct, said push-rod member cooperating with said air ducts to apply supporting force to said hood assembly whereby the hood assembly may be rotated about its center of gravity to a desired angle of tilt.
