ABSTRACT: A portable and collapsible clothes drier receptacle mounted on a foldable frame and adapted for attachment to a heater-blower unit.
PATENTED mw 41971 I INVENTOR HA my BRAHM 4r ORNKQ PQRTABLEAND COLLAPSIBLE CLOTHES DRIER yRECIIP'IACLE BAcxGRouNb or INVENTION SUMMARY OF THE INVENTION It is an object of this invention to provide a drier receptacle a conventional hair dryer.
It is another object of this invention to provide a drier receptacle assembly' which is collapsible into a very small compact unit for easy portability. I
It is yet another, object of this invention to provide a drier receptacle assembly made of inexpensive yet sturdy materials to afford the desired results withoutundue cost.
It is a still further object of this invention to provide a portable and collapsible clothes drier receptacle assembly adapted to be operatively connected to a heater-blower unit, said drier receptacle assembly comprising a flexible .rectangularly shaped closed receptacle having a top, bottom, end and sidewalls, an access flap portion formed in the receptacle top, means for fastening the free edges of the flap portion to said top, said receptacle being provided with a plurality of exhaust openings, reinforcing and supporting seams affixed to and transversely of the upper inner-portion of each end wall, flexible lines connected to and extending between said reinforcing and supporting means, air distributing means positioned in the receptacle, air intake means connected to the air distributing means and extending through a portion of the receptacle to provide an outside connection to which a heater-blower unit may be attached tofurnish hot dry air to the air distributing means and means for supporting the receptacle in erected operative position.
Other objects and advantages will become more apparent when considered in conjunction with the following detailed description and drawing, showing by way of example several embodiments of this invention.
BRIEF DESCRIPTION OF THE DRAWING FIG. I is a perspective view of the preferred embodiment of this invention in assembled position ready for use;
FIG. 2 is a partial view in perspective illustrating an alternative manifold arrangement, and v FIG. 3 is a partial view in perspective showing yet another alternative manifold arrangement.
As illustrated in FIG. 1 of the drawings, the portable drier unit comprises a foldable frame assembly 12 including a having parallel legs 18 and 20 and 22 and'24 respectively. Parallel legs 18 and 20 are connected by a horizontal member 26 while legs 22 and 24 are bridged by horizontal member 28. The U-shpaed supports 14 and 16 are crossed intermediate their leg lengths and pivotally connected at their point of inapertures 58 for the exiting-of the moisture laden air from assembly adapted to cooperate with the heater-blower unit of within the receptacle.
A reinforcing'and support bar 60 is positioned within the receptacle 40 and secured to the upper inner face of each of the end walls 46 and 48. These bars 60 act as the support for lines 62 which serve as clothes lines for the receptacle. Both upper transverseedges of the receptacle have a mounting flap 64 secured thereto. The free end of the flap 64 is passed over the respective horizontal members 26 and 28 of the U-shaped supports and secured to adjacent bar 60 by means of fasteners 66 The receptacle bottom 42 has a manifold 70 positioned on its inner face generally-throughout the length of the bottom. This manifold 70 is semicircular in cross section and has a plurality of holes 72 through which hot air is introduced into the receptacle. The end of the manifold 70 contiguous toend wall 48 is closed while the other end is open and connected to intake plate 74 secured to end wall 46. A nipple 76 extends from the plate 74 on the outside of the wall 46 and receives a flexible conduit 78 which-in turn is connected to heater-blower unit 80.
It is believed that the operation and use of the unit iS reasonably apparent in view of the foregoing description. Even'so, a brief description follows. With the portable drier .unit 10 in erected position, as illustrated in FIG. 1', the zipper 56 is operated to free flap portion 54 whereupon the items to be dried are hung on lines 62 provided for thispurpose. After the receptacle is filled, the zipper is again pulled to close the top 44. Next, the heater-blower unit 80 is started and hot dry air is forced through conduit 78 into manifold 70 arid out through holes 72. The moisture laden air is exhausted through apertures 58 in the flap portion 54. As soon as the items within the receptacle are dry, they may be removed.
' pair of U-shaped supports 14 andl6, said U-shaped supports tersection by means of pivot pin 30. The free ends of the legs I8, 20, 22 and 24 mount swivel caster 32 to provide easy mobetween legs 18 and 22 to maintain the frame assembly in erected position.
The folding frame assembly 12 supports a collapsible clothes drier receptacle 40 which is generally rectangular in shape having a bottom 42, top 44, end walls 46 and 48 and sidewalls 50 and 52. Plastic material is quite advantageously used for the receptacle, particularly the types which are readily heat scalable. The top 44 is provided with a flap portion 54 whose three sides are secured to the top by means of a zipper 56. The flap portion 54 is provided with a plurality of exhaust It is contemplated that the manifold 70 of FIG. I may be modified, and in this connection, attention is directed to FIG. 2 wherein the'drier receptacle is provided with a flexible manifoldlike cover 92 extending over the entire bottom of the receptacle in spaced relation thereto to provide a hot air chamber 94. The cover 92 has a plurality of evenly spaced holes 96 over its entire surface for the discharge of hot dry air into the receptacle. The same type intake plate 98, as in FIG. I, is used in this embodiment.
Yet another modification is shown in FIG. 3 wherein a different manifold arrangement is depicted. In this embodiment, the manifold comprises a flexible rectangularly shaped tube 100 secured around the upper inner portion of the drier receptacle 102. The exposed inner face of the tubular manifold 100 has a plurality of hot air feed holes 104 for directing the hot dry air into the upper portion of the drier receptacle. The usual conduit plate 106 is provided to feed the hot air from the heater-blower unit to the manifold 100. Obviously, the discharge openings in this embodiment would be located in the bottom of the drier receptacle.
In all of the constructions illustrated and described, use of a transparent heat scalable plastic for the drier receptacle is quite advantageous. The supporting frame assembly can be made of aluminum, stainless steel or even other materials depending mainly on cost factors. The heater-blower unit may be of the type usually associated with portable hair drier units although other types of heater-blower units could obviously be employed.
Many conventional additions could be made to the basic units as described above. For example, means can be provided to communicate with the entering hot air to introduce a scent into the drier receptacle. Further, an ultraviolet light could be positioned within the drier receptacle to deodorize and purify the air and items in the receptacle.
