Abstract
Abstract A combination hair drying appliance which can be used either as a gun-type hair blower/dryer or an in-line hair styler/dryer. The two separate uses are created by two separate mechanical configurations of the appliance, each configuration established when the handle portion of the appliance is rotated with respect to the main body portion to become either perpendicular to or in-line with the body portion.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
236 words
A combination hair drying appliance comprising a housing, a motor actuated fan mounted in said housing, an air inlet means and air outlet means formed in said housing, heater means mounted in said housing between said fan and said air outlet means, said housing being characterized by an elongated cylindrical portion having an elongated handle portion connected to one end thereof, said handle portion being rotatably movable with respect to said cylindrical portion between a first position in which said handle portion is substantially perpendicular to said cylindrical portion and a second position in which said handle portion is in longitudinal coaxial end-to-end alignment with said elongated cylindrical portion, said air outlet means including a first opening provided at the opposite end of said cylindrical portion from said connected end in longitudinal alignment with said fan and a second elongated, longitudinally extending opening provided in a side wall of said cylindrical portion adjacent said opposite end of said cylindrical portion, said fan causing air to flow through said cylindrical portion whereby said air is heated by said heating means and discharged primarily through said first opening, and adapter means selectively mountable on said cylindrical housing portion adjacent said second opening of said air outlet means and having plate means for blocking said first opening whereby said heated air is discharged through said second opening generally at an angle to the axis of said cylindrical housing portion.
Claim 2
Dependent Claim
236 words
A combination hair drying appliance comprising a housing, a motor actuated fan mounted in said housing, an air inlet means and air outlet means formed in said housing, heater means mounted in said housing between said fan and said air outlet means, said housing being characterized by an elongated cylindrical portion having an elongated handle portion connected to one end thereof, said handle portion being rotatably movable with respect to said cylindrical portion between a first position in which said handle portion is substantially perpendicular to said cylindrical portion and a second position in which said handle portion is in longitudinal coaxial end-to-end alignment with said elongated cylindrical portion, said air outlet means including a first opening provided at the opposite end of said cylindrical portion from said connected end in longitudinal alignment with said fan and a second elongated, longitudinally extending opening provided in a side wall of said cylindrical portion adjacent said opposite end of said cylindrical portion, said fan causing air to flow through said cylindrical portion whereby said air is heated by said heating means and discharged primarily through said first opening, and adapter means selectively mountable on said cylindrical housing portion adjacent said second opening of said air outlet means and having plate means for blocking said first opening whereby said heated air is discharged through said second opening generally at an angle to the axis of said cylindrical housing portion.
Claim 3
Dependent Claim
89 words
A combination hair drying appliance as claimed in claim 1 wherein said connected end of said cylindrical housing portion abuts the end of said handle housing portion to which it is connected along a junction plane, said junction plane being disposed at an angle of approximately 45° with respect to each axis of said two housing portions, and means on the abutting ends of said two housing portions for rotatably attaching said cylindrical portion to said handle portion whereby one portion swings about the axis of the other portion.
Claim 4
Dependent Claim
111 words
A combination hair drying appliance as claimed in claim 2 wherein said attachment means comprises a circular opening formed in a first end wall provided at the abutting end of one of said housing portions and defining an annular edge, a cylindrical extension formed on a second end wall provided at the abutting end of the other of said housing portions, said extension extending through said opening and having an enlarged head defining an annular slot between said head and said second end wall of said other housing portion with said annular edge of said opening being rotatably received within said annular slot whereby said two housing portions are rotatably interconnected.
Claim 5
Dependent Claim
68 words
A combination hair drying appliance as claimed in claim 3 wherein said attachment means further comprises a pair of diametrically opposite projections extending laterally from said enlarged head of said other housing portion, and a stop plate member on said one housing portion located adjacent said opening whereby engagement of said projections with said stop plate member will limit rotation of said head to 180° in either direction.
Claim 6
Dependent Claim
180 words
A combination hair dryer appliance comprising an elongated body portion, a motor actuated fan mounted in said body portion, an air inlet and first and second air outlets formed in said body portion, heater means mounted in said body portion between said fan and said air outlets, said first air outlet being generally axially aligned with said fan and said second air outlet being disposed forwardly of but to one side of the axis of said fan, an elongated handle portion rotatably attached to said elongated body portion, said handle portion being rotatable with respect to said body portion between a first position in which said handle portion is in longitudinal coaxial end-to-end alignment with said body portion and a second position in which said handle portion is angled with respect to said body portion, said fan causing air to flow through said body portion past said heating means and to be discharged primarily through said first air outlet, and means selectively mountable over said first air outlet only whereby said heated air is discharged through said second air outlet.
Claim 7
Dependent Claim
180 words
A combination hair dryer appliance comprising an elongated body portion, a motor actuated fan mounted in said body portion, an air inlet and first and second air outlets formed in said body portion, heater means mounted in said body portion between said fan and said air outlets, said first air outlet being generally axially aligned with said fan and said second air outlet being disposed forwardly of but to one side of the axis of said fan, an elongated handle portion rotatably attached to said elongated body portion, said handle portion being rotatable with respect to said body portion between a first position in which said handle portion is in longitudinal coaxial end-to-end alignment with said body portion and a second position in which said handle portion is angled with respect to said body portion, said fan causing air to flow through said body portion past said heating means and to be discharged primarily through said first air outlet, and means selectively mountable over said first air outlet only whereby said heated air is discharged through said second air outlet.
