Referring now first to FIGS. 1 to 5 of the drawings, the hair curling attachment comprises an elongated and cylindrical or tubular member 10 having a slight taper. The left hand end of member 10 has a pair of notches 11 formed therein so that the connector or coupling 12 at the outer end of a hair dryer hose 13 can be quickly and removably'connected thereto. The hose coupling 12 is described in detail in Chambers et al. Patent No. 3,168,- 382 issued Feb. 2, 1965 and assigned to the same assignee as the instant patent application. It has a pair of outwardly spring biased latching elements 14 which snap iuto grooves 11 when the connector 12 is inserted into the left hand end of member 10. To remove the connector 12 from the curling attachment, it is only necessary to depress the portions 15 of the latches 14 against the bias of their spring 16.
` The right hand end of member 10 is adapted to be quickly and removably connected to three different sizes of hair curler forms indicated in broken lines in FIG. 4
by reference numerals 17', 17 and 17 The right hand outermost extremity of member 10 is provided with a reduced diameter or shouldered nose portion 10. A pair of spaced rows of latching tabs or shoulders 18 and 18 are provided inside nose 10' for the purpose of quickly and removably connecting the smallest curling form 17 to the curling attachment. A pair of spaced rows of latching tabs or shoulders 18 and 18" are also provided on the outside of nose V10. The two rows of tabs 18 and 18 removably latch the intermediate size hair curler form 17". The row of tabs 18 are spaced from a shoulder 19, and the tabs 18 and shoulder 19 removably latch the large size curler form 17"' to the curling attachment.
The curling forms 17', 17, and 17 are readily available on the market in drug and notions stores or the like. They comprise pliable plastic screen-like cylinders having beads 20 at their opposite ends. Cylindrical brushes cornprising a central wire form 21 and radiating brush bristles 22 are located inside the curling forms. The brush bristles 22 protrude slightly through the apertures 23 of the curling forms. As is Well known in the art, hair is curled or rolled on the curling forms and the curled hair will not unintentionally unroll because it is retained on the for-m by the protruding bristles 22. Since the screen-like'cylinders of the curling forms are constructed from pliable plastic material, their ends can be easily forced past the tabs 18, 18", and 18"'. The tabs, of course, will enter the apertures 23 to removably latch the curling forms on the nose 10' as is illustrated in the drawings.
Since hot air is conducted by the curling attachment from the hose 13 to the curling forms, the curling attachment will become Warm. At the hot or high setting of the not shown motor-fan-heater unit of the hair dryer, the curling attachment may become rather warm for comfort- .able hand holding or grasping of the curling attachment. Therefore, in the form of the invention illustrated in FIGS. 1-5, the tubular member 10 is given a double walled heat insulated construction. More particularly,
.the member 10 has concentrically spaced inner and outer walls 10" and 10". Between the walls 10 and 10" is a 'dead air space 24. The dead air space 24 is close-d at its right hand end by the shoulder 19 and at its left hand end by a heat insulating washer or ring 25. The washer '25 is held in place by integral tabs 26 which are formed so that a strong blast of hot air isnt directed immediately against the head while the Woman is connecting up the attachment to a hair curler form on her head. A The curling attachment comprises a round tubular member 30 having a slight taper. The left hand end has grooves 19 as before described for purposes of connecting a hair dryer hose coupling or connector 12. At its right hand end, theres a nose portion having two reduced diameter portions V31 and 32 and an internal circular shoulder 33 Y on the portion 31. The nose portion is adapted to Yreceive three diiferent sizes of hair curler forms 17, 17", and 17 as illustrated in broken lines in FIG. 6 and similar to those previously described. The smallest curler 17 fits inside portion 31 against the shoulder 33. The in-between sizecurler 17" tits on the outside of portion 31 against a shoulder or step 34 located between portions 31 and 32.- The largest curler 17 iits on the outside of portion 32 against a shoulder 35 at the left hand end of portion 32. The curlers are retained on the nose of the attachment by a snug or friction fit. The heat insulation means for comfortable holding of tubular member 30 comprises a plurality of integral and spaced lengthwise extending fins 36.
For purposes of venting the hot air to the atmosphere,
Va vent opening'37 and valve 4G andvalve seat 42 are provided at the left hand end of tube 30 land a valve 38 and kvalve seat 39 are provided at the right hand end of tube 30; The opening 37 isdeiinedbyan integral enlarged portion 30' which extends for about 90 degrees about the Vleft hand edge of tube 30. Portion 30 has a larger radius Y than the left hand end of tube 30 so as to be spaced there:-
V from to deine the opening 37. The opening 37 is opened andclosed by the valve element 40 integrally formed on the left hand end of a valve slide actuator 41. The valve 38 is integrally formed at the right hand end of valve slide 41. When the slide 41 is moved to the right, valve 38 seats on valve seat 39 to close olf air flow through tube 30. At
the same time, the valve 40 is moved off the contiguous edgec42 of theY hose connector 12 to open the vent 37. That is to say, edge 42 is the equivalent of a valve seat for the valve 40. When slide 41 is moved to the right, valve width of the enlargement to completely close olf the opening 37 when the slide 41 is moved to the left. At theY right hand end of the device, the shoulder 33 is aligned with the shoulder 34 so as to comprise an integral exteni sion thereof, and the right hand valve seat 39 is formed in the back side of shoulder 33 which faces the right hand valve element 38. The valve element 38 is circular, as is its valve seat 39, and the axes of these two parts are aligned with the axis of the tubular member 30. The slide 41 is a common valve control or actuator for each of valves 33 andf 40. Y v
The thumb actuator 46 is actually carried by an integral resilient finger part 41 of slide 41. The finger 41 is cut out of slide 41 by a U-shaped vgroove 48. The light handV Y end of finger 41' is free whereasthe'left hand end is integral with the slide 41. Since .the slide 41 is constructed from plastic the finger 41 is resilient. That is to say, iinger 41 Ycan be pushed in a direction away from the slideV Ygroove 43 when inserting slide 41' incits groove 43 when assembling the device. Due to the taper of the slide 41 and its groove 43, the slide is inserted in' groove 43 in a left to right direction. At this time, the linger 41 is pushed in so that the button`46 rides on the'inside surface of groove 43 until it reaches its notch 47 after whichit will snap intD place therein.
Actually, inV both Vforms of the invention the hair curler attachment tubes are constructed from molded plastic. In
the first form of the invention, the tube Vis a composite a latch spring 49 to latch the slide 41 in either Vits left hand vent closed or right hand vent open extreme posi-1 tions. The spring 49 is seated in `a vgroove'tl formed in this other halfY of the tube` 30 which other half is they Y upper half whenviewingthe drawings. The valve 38 is r carried by the front end of slide 41 by an integral exten to'the atmosphere. `When the hot air is vented through opening 37 there is no blast of air leaving the nose of the tube 30 which will impinge on the womans head as she is connecting tube 30 to onejof the hair curler forms.
The slide 41 extends Ylengthwiseiof tube 30 and it has a width'equivalent to about 90 degrees of the tube 30. A slide groove 43 extends lengthwise of tube 30. The slide Allais-nested in the slide groove 43 for back and forth movement therein; Opposite side edges 44 of slide 41 are tapered and the tapered edgesV 44 iit beneath undercut shoulders 45 formed along opposite sides of the groove 43. Actually, this slide 41 and its groove 43 have a gradual reduced width or taper. from left torright. Therefore, it is possible to'rciompletely withdraw the slide 41 from within tube 30 by pulling it out in a left hand direction. However, normally movement of slide 41 is limited to just a sufiicient distance to operate the'valves 38 and 40. Movement of slide 41 is limited by a thumb actuator 46 integrally formed on slide 41 and which rides in a notch 47. formed in the side of tube 30. Y
The sli-de guide groove 43 Vat its right hand'end extends is about degrees wide similar to the about 90 degree sion 41". Behind the valve 38 is an integral bridge portion`51 having arfrontV latch notch 52 and a rearV latch sloped surface 53. Whenthe slide is moved forwardly to close valve 38 and open valve 40 and vent 37 the spring 49 catches on surface 53Vto retain the slide in the posi-k 'Y tion shown in FIG.V'7.'When the slide'41is moved to the' left to open valve/*38 and close'valve 40 and vent 37,V
the spring 49 catches in the notchSZVto retain the. slide in the position shown in FIG; 6. c
Once the parts are assembled as shown in the drawings,
the thumb actuator 46 is retained captive in its notch 47V by an integral strut 54`formed on finger 41 and a cooperative guideridge 55 formed on the upper half of the tube. As shown in the drawings, theV free or upper end of strut 54 moves in a lengthwise extending notch 56V formed in c the guide 55 which also extends-lengthwise ofV tube 30.
The semi-cylinders of the Ytube can be connected togetherY Vby a suitable'cement or by not shown clamping rings or theY like slippedV over the tube afterk the partsrare. assem bled together. To disassemble the device,'the semi-cylinders are iirst removed with respect to each other. This removes the ridge 55 from abutting relationship with respect toV the free or upper end of strut 54. This being so, the thumb button 46 can then be pushedv inV to clear its notch 47 so that the slide 41 is free to be removed by withdrawing it from its guide 43 in a left hand direction.
It will now be seen that the invention provides a hair curler attachment forV hair dryersY which is simple and easy to use and'has a minimum number of parts whereby itis low cost. In addition, the device is versatile inas-Y much as it is adaptable for connection to existing Vhair, dryer hoses and a range of different sizes of existing hair curling forms.
While there have been shown and described particular i embodiments of the invention, it will be obvious to those skilled in the art that changes Vand modifications maybe made without departing from the invention, Iand that it is intended by the appended claims to cover all such changes and modications as fall within the true spirit and scope of the invention.
