Ponczek, Chicago, 111., assignor to Sunbeam Corporation, Chicago, 111., a corporation of Illinois Filed Aug. 8, 1966, Ser. No. 571,078 4 Claims. (Cl. 34-99) ABSTRACT OF THE DISCLOSURE A compact portable hair dryer case having a pair of abutting case halves one of which receives a combination motor, blower, and heater unit with a collapsible hose stored therein and the other of which provides storage for a power cord and a hat attachable to said hose.
This invention relates to a hair dryer, and more particularly, to a low cost and portable hair dryer.
It is an object of this invention to provide a low cost, compact and portable hair dryer which contains all the necessary apparatus for performing a hair drying operation.
The instant invention uses the invention described and claimed in co-pending patent application Ser No. 466,- 307 filed June 23, 1965, and now Patent No. 3,261,107 by Ponczek et al. and assigned to the same assignee as the instant patent application. The Ponczek et al. patent application discloses a compact hair dryer comprising a tubular casing or housing containing a motor-blowerheater unit and having a lengthwise expansible and collapsible air hose stored in a hose storage compartment formed at one end of the tubular casing or housing. Briefly, in the instant invention the Ponczek et al. device is housed in a simulated leather carrying case which has two rectangular shaped boxes which close on each other. The Ponczek et al. device is positioned in the bottom box, and the top box is removably hinged to the bottom one to provide a storage compartment for the cap and electric cord of the hair dryer. The hose is stored in the outlet end of the tubular housing of the motor-blowerheater unit of the hair dryer and a closure flap or door at the corresponding end of the bottom box affords access to the stored hose. In this manner the simulated leather carrying case provides a low cost, compact and portable hair dryer unit which contains all the parts necessary for performing a hair drying operation.
The features of the invention which are believed to be novel are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and operation, together with further objects and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawings; in which:
FIG. 1 is a perspective view of a hair dryer showing a preferred form of the invention;
FIG. 2 is an enlarged longitudinal sectional view taken through the air dryer of FIG. 1;
FIG. 3 is a top plan view of the hair dryer with the carrying case being in open position;
FIG. 4 is a broken away end elevation view when viewed from the right hand end of FIGS. 1 and 2; and
FIG. 5 is an end elevation view when viewed from the left hand end of FIGS. 1 and 2 and showing the end closure flap for the bottom half of the carrying case in open position.
Referring now particularly to the drawings, shown therein is a hair dryer comprising a carrying case having two generally rectangular and elongated top and bottom boxes 11 and 12 respectively. These two boxes are hinged 3,386,184 Patented June 4, 1968 together for opening and closing movement with respect to each other. The top box 11 is adapted to have a collapsible hair dryer cap 13 and flexible electrical extension cord 14 stored therein. The two boxes 11 and 12 are hin cd together by hinge means 15. They are latched closed together by latch means 16. The hinge means 15 are of the type which is well known in the art and lengthwise movement of the two boxes with respect to each other will cause separation of the hinge pin 17 and its hinge element 18 which are connected to the box 11 from the hinge element 19 which is connected to the box 12.
The bottom box 12 contains a housed motor-blowerheater unit and stored hose device of the type disclosed in the previously mentioned Ponczek et a1. patent application. The motor, blower, heater, and stored hose thereof are indicated by the reference numerals 261-23 respectively. The components ZlB-ZS are contained within a tubular housing 24. The left hand end of housing 24 is provided with a hose storage compartment 25 for collapsing the expansible hose 23 therein for storage of the hose in the tubular member 24. The top of tubular member 24 is provided with a control switch finger operating knob 26 and a pair of electrical terminal pins 27 for purpose of connecting the electric cord 14 thereto. The not shown switch of the knob 26 and the terminal mounting board and other detailed components of the pins 27 are actually contained in a protruding switch housing portion 28 of the tubular member 24. Opposite ends of the tube 24 are open. The right hand end of tube 24 comprises its air inlet end, and the left hand end of tube 24 comprises its air outlet end.
Opposite ends of the hose 23 have annular fittings 29 and 30 connected thereto. The hose 23 is constructed so that it may be collapsed and expanded within the range of from several inches to several feet. The inner end of hose 23 is connected to the left hand air outlet end of tube 24 by retaining the right hand hose fitting 29 captive within the hose storage compartment 25. Opposite ends of the hose storage compartment are defined by internal beads 31 and 32 formed at opposite ends of compartment 25. The fitting 29 can slide back and forth within the compartment 25 between the limits defined by the spaced beads 31 and 32. When the hose 23 is stored in compartment 25 the fitting 29 will bottom against the inner bead 31. When hose 23 is withdrawn from compartment 25 for removable connection to the hair dryer cap 13 the fitting 29 will bottom on the outer bead 32. The outer fitting 3i can be removably connected to the not shown air inlet opening of the hair dryer cap 13 by virtue of latch means 33 formed on the outer end of fitting 3!). The left end of tube 24 and the fitting 30 have cooperative means formed thereon for retaining the hose 23 removably stored in the compartment 25. Such means comprises an internal slotted ring 34 on the left hand end of tube 24 and spaced lugs 35 formed on the right hand end of fitting 30. After the hose 23 is stuffed into the compartment 25 the lugs 35 can be passed through the slots 36 in the ring 34. When the lugs 35 are located beyond the ring 34, if the fitting is given a partial turn, the lugs 35 will catch on the ring 34 to retain the collapsed hose 23 removably stored in compartment 25. For withdrawal of hose 23 the fitting is rotated until lugs 35 are aligned with slots 36 after which the fitting 30 can be disengaged from the outer end of tube 24 to withdraw the hose 23. The fitting 3b is preferably constructed from plastic material which can be deformed by finger pressure so as to release the latches 33 from the not shown air inlet opening formed in the hair dryer cap 13. The projecting portion 37 on fitting 30 located between the latches 33 and the lugs 35 is a finger pressure lug for purposes of squeezing or deforming the fitting 3t] slightly so as to disengage it from the hair dryer cap.
As will be clear from a consideration of the detailed description found in the Ponczek et a1. patent application, the tube 24 is actually split lengthwise thereof into semicylindrical housing sections. The internal components 2tl' 23 are preassembled in one of the housing sections and then the motor-blower-heater and hose unit is completed by closing the one housing section with the other housing section. The two housing sections are retained closed on each other by two end fittings therefor 38 and 359. These tWo end fittings 38 and 39 also comprise the means for retaining the motor-blower-heater unit with its hose storage compartment 25 mounted in the bottom box 12 of the portable carrying case. The opposite ends of tube 24 have beads or shoulders 49 and 41 formed thereon. The fittings 38 and 39 are slipped about the opposite ends of the tube 24 and butted up against the beads 46 and 41 respectively to retain the two sections of the tube 24 closed on each other. The right hand end fitting 38 is provided with a pair of integral top and bottom mounting lugs 42. These lugs 42 are fastened to the top and bottom of the box 12 by means such as screws 43.
By viewing PEG. 4 it will be seen that the two boxes 11 and 12 have the cross sectional shape of an isosceles trapezoid. The base portions of the isosceles trapezoidal shape are open and face each other. The fitting 39 also has an outer isosceles trapezoidal shape, see FIG. 5. It is provided with a central annular ring 44 which receives the left hand end of the tube 24 therein. The ring 44 and the outer peripheral portion of the fittin 39 are interconnected by an integral grill work 45. The fitting 39 is also provided with top and bottom mounting lugs 46 for connection of the fitting 39 to the top and bottom of the base box 12 by means such as screws 43. The top of the carrying case is provided with a carrying handle 47 and the bottom of the carrying case is provided with rubber or the like support pads 48. The bottom screws 43 pass through the bumpers 48 and have their heads embedded therein. The bottom screws 43 of course also pass through aligned apertures formed in the bottom surface of the simulated leather bottom box 12. The bottom of the box 11 is open so as to afford access to the cap 13 and cord 14 stored therein. The top of the box 12 is also open to afford access to the switch control 26 and the terminal 27. The opening in the top of bottom box 12 is indicated by reference numeral 49. Opening 49 is defined by an inturned flange portion Sit on the top of box 12. The opening 49 is actually closed by a decorative metallic cover plate 51. Plate 51 has an opening 52 formed therein which conforms to the contour of the switch housing 28. The top screws 43 extend through alignedopenings formed in the plate 51 and the flange portion 50 into the top lugs 42 and 46 on the end fittings 38 and 39 resp ctively.
The end of the box 12 which corresponds to the vair inlet end of tube 24 is provided with air inlet openings 53. A metal screen or the like 54 is disposed between the openings 53 and the rotating air blower 21. The other end of bottom box 12 is open and provided with a hinged door 55. The door 55 comprises an end flap which is connected at its top to the left hand top edge of box 12. The boxes '11 and 12 have their side walls connected together by well known expedients such as stitching. The end flap 55 has an integral portion 56 connected to its top edge which comprises its hinge connection to the top of the left hand end of box 12. When the door 55 is hinged down to its closed position it is retained closed by two elements 57 and 58 respectively connected to the door 55 and underside of box 12. The elements 57 and 58 comprise releasable snap fastening means for retaining the flap 55 closed. All of the latch means 57, 58 and 16, of course, are finger operated. The latch element 57 is connected to the bottom edge of the door 55 by a flexible strap so that the latch element 57 will reach the latch element 58.
The cap 13 is actually constructed from plastic sheet material in a manner which is well known in the art so that it can be collapsed or bunched up into a very small volume. Actually, the storage compartment in the box 11 for the cap 13 and cord 14 has room to spare so as to receive still other devices useful in drying the hair such as a few hair curlers which, however, are not illustrated in the drawings. In use of the hair dryer the carrying case may be rested on a table top or the like on its bumpers 48. However, the top box 11 can also be separated from the bottom box 12 and the bottom box 12 carried off the shoulder of the hair dryer user. For this purpose an eyelet 6th is connected to the left hand end of the plate 51. A cord or shoulder strap or the like can be threaded through the eyelet 60 so as to sling the bottom box 12 and its contained motor-blower-heater unit off the shoulder of the hair dryer user. The hose 23 contained within the bottom box 12 of course will be withdrawn therefrom and connected up to the hair dryer cap 13 which will be positioned on the hair dryer users head. The cord 14 will be unraveled and connected at one end to the terminal pins 27 and at the other end to an electrical wall socket or the like. The cord 14 is provided with a sufficient length to give the hair dryer user freedom of movement to perform other tasks while the motorblower-heate-r unit is operating to blow drying air through the expanded hose 23 into the hair dryer cap positioned on the hair dryer users head. The hose 23 of course is withdrawn from the bottom box 12 by unlatching the end flap or door 55 and then releasing the fitting 30 from the left hand end of the hose storage compartment 25 and connecting the fitting 39 to the air inlet opening of the hair dryer cap 13. It will now be seen that the invention provides a low cost, compact and portable hair dryer which is completely self-contained in that it contains all the necessary components or apparatus for performing a total hair drying operation.
While there has been shown and described a particular embodiment of the invention, it will be obvious to those skilled in the art that changes and modifications may be made without departing from the invention, and therefore, it is intended by the appended claims to cover all such changes and modifications as fall within the true spirit and scope of the invention.
