Benton Harbor, Mich. 49022 Filed July 13, 1970, Ser. No. 54,204 Int. Cl. F26b 13/00 US. Cl. 34-151 11 Claims ABSTRACT OF THE DISCLOSURE A collapsible clothes dryer having a vertically oriented central duct in which a plurality of clothes supporting ducts project laterally outwardly therefrom. The clothes supporting ducts are pivotally connected to the central duct so as to be shiftable from their laterally projecting position to a position generally paralleling the central duct. Each clothes supporting duct has one end in communication with an opening in the central duct when positioned in its laterally projecting position and includes a plurality of openings which extend longitudinally along the clothes supporting duct. Means are provided for introducing heated air into the central duct. The heated air enters the clothes supporting ducts and passes out the openings therein to cause drying of the clothing carried by the clothes supporting ducts. A flexible hood is positioned over the clothes supporting ducts and serves to retain the heat from the air which passes out the openings in such ducts.

SUMMARY OF THE INVENTION This invention relates to a clothes dryer and has specific application to a clothes dryer which can be collapsed and conveniently stored when not in use.

In this invention a central duct is provided with one end thereof preferably closed. A plurality of clothes supporting ducts or tubular arms project laterally from the central duct at longitudinally spaced intervals along the duct. Means are provided for pivotally connecting each clothes supporting duct to the central duct so as to enable each clothes supporting duct to be swung from its laterally projecting position when in use to a position generally paralleling the central duct when the dryer is stored. Each clothes supporting duct has one end in communication with an opening in the central duct when positioned in its laterally projecting position. The central duct is supported in an upright position when the dryer is in use with its closed end-uppermost. Means is provided for introducing heated air into the central duct which'passes into the clothes supporting ducts and out the openings therein. A flexible hood, which can be conveniently folded and stored, is preferably positioned over the clothes supporting ducts and serves as a means for retaining the heat from the air which is emitted from the openings in the clothes supporting ducts.

When it is desired to store the dryer between periods of use, the hood is removed from the dryer and folded. The clothes supporting ducts are then folded against the central duct so as to provide a compact unit which can be conveniently stored in a minimum of space with the folded cover. The dryer of this invention would have application in those homes having a minimum of available living space. This device would also have application for hunting, fishing and skiing lodges in which the dryer may be quickly assembled and utilized to dry clothing and then disassembled and packed when its usage is not desired. The means utilized to provide the drying air can be an integral heater and blower unit which may be gasoline or electrically powered.

Accordingly, it is an object of this invention to pro.-

vide a clothes dryer which is of economical manufacture and which can be collapsed and conveniently stored in a minimum of space.

Another object of this invention is to provide a collapsible dryer for clothes, including gloves, shoes and boots, which is of efficient and simple operation.

Still another object of this invention is to provide a collapsible clothes dryer which can be utilized at hunting, fishing, skiing and other type lodges and recreational places and which can be operated upon battery or gasoline power.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments illustrated are not intended to be exhaustive or to limit the invention to the precise forms disclosed. They are chosen and described in order to best explain the principles of the invention and its application and practical use to thereby enable others skilled in the art to best utilize the invention.

The embodiment of the clothes dryer illustrated in FIGS. 1-4 includes a central tubular member or duct 10 which is supported when the dryer is in use in an up right orientation by legs 12 located adjacent the lower end 14 of the duct. The upper end 1 6 of the duct 10 is preferably capped. Legs 12 are preferably in a tripodic arrangement and connected to duct 10 so as to be foldable into a position generally paralleling duct 10 when the dryer is nto in use. The means of attaching legs 12 to duct 10 can assume any of a variety of constructions and may consist of hinges 13 interconnecting the lower end 14 of duct 10 to the upper end portions of legs 12. Each hinge 13 is spaced from the upper edge 18 of its connected leg 12 so as to enable the lower end portion of the leg to be swung outwardly and the leg angled, as illustrated in FIG. 2, with upper leg edge 18 abutting the side of duct 10. To enable the dryer to be moved from location to location while standing, each leg 12 may have a caster 22 attached to its lower end.

A plurality of tubular arms or ducts 24 project laterally outwardly from duct 10. Each duct 24 is pivotally connected to duct 10 by a hinge 26 or similar attachment means at end edge 28 so as to permit the duct to be swung between its operative laterally projecting position with end edge 28 thereof abutting the side wall of duct 10 as illustrated in FIG. 1 and a collapsed position generally paralleling duct 10 as illustrated in FIG. 2. The opening in end 28 of each duct 24 registers with an opening 30* in duct 10 when duct 24 is in its laterally projecting position. The opposite end 32 of each duct 24 is preferably capped. At least one and preferably two or more rows of openings 34 extend longitudinally along the lower side of each duct 24. Although rows of openings 34 are preferred, other type opening means, such as longitudinally extending slots, may be utilized in ducts 24.

Ducts 24 are preferably of equal length and are divided into two or more groups spaced longitudinally along duct 10. The ducts 24 in each such group lie radially disposed and in coplanar relationship about the axis of duct 10. In the illustrated embodiment of this invention, there three groups 25a, b and c of ducts 24 with each such group consisting of three equiangularly spaced ducts or arms lying in a plane perpendicular to the axis of duct 10. The ducts 24 of the middle group 2512 of ducts are preferably positioned out of angular alignment with the other two groups 25a and 25c of ducts 24.

The ducts 24 in the uppermost group 25a of ducts are preferably inwardly spaced from upper end 16 of duct 10 with each such duct 24 carrying a support 38 at its outer end 32. A hood 40 having enclosed top 42 and a depending skirt portion 44 is positioned over upper end 16 of duct 10 and around ducts 24 when duct 10 is supported in its upright orientation with arms 24 thereof projecting laterally outwardly. Hood 40 is preferably constructed from a flexible fireproof material and has its top 42 supported by upper end 16 of duct 10 and supports 38 of ducts 24 in duct group 25a with skirt portion 44 thereof encircling, preferably with clearance, duct groups 25b and c. A combined heater element and blower unit 46 is positioned so as to direct heated air into duct 10 at the lower end 14 thereof and upwardly into the duct. The heated air passes through openings 30 in duct 10 and into ducts 24 where it exits through duct openings 34. The heater element and blower unit may consist of an electrical heating unit combined with an electrically powered centrifugal blower, or a gasoline powered blower utilized in conjunction with a gas or oil actuated heating unit. The heater element and blower unit 46 can rest upon floor 49 below the lower end 14 of duct 10, as illustrated, so as to direct the air directly up through the interior of duct 10. As an alternative, the lower end 14 of the duct may be capped and a flexible hose attached between the lower end of duct 10 and unit 46 for directing heated air from the heater and blower unit which may be positioned within the near vicinity of duct 10. Clothes may be draped over ducts 24 or suspended from hangers or drying racks which are supported by hooks 48 attached to ducts 24.

Heated air in passing through duct 10 and into ducts 24 exits through openings 34 in ducts 24 and passes over and around the clothes, thereby causing the drying thereof. To assist in directing the air flow into ducts 24, a plurality of baffies 50 may be connected within duct 10 and positioned adjacent openings 30 therein. Hood 40 serves as a retainer for the heated air as it is emitted from ducts 10, thus accelerating the drying of the clothes. The

heated air escapes from the open bottom of hood 40 and causes skirt portion 44 of the hood to expand and be held out of contact with the articles of clothing supported by ducts 24.

In order to promote circulation of the air within hood 40, a fan 52 (see FIG. 5) may be journaled about duct 10 between upper end 16 of the duct and upper duct group 25a. Fan 52 is supported between spaced collar members 54 which are suitably secured to duct 10. The ducts 24 of upper duct group 25a have openings 56 which are formed in their upper surfaces and which are posi tioned under the vane portions of fan 52. As air is forced upwardly into duct 10 and outwardly into extended ducts 25 by blower units 46, a suflicient amount of the air is emitted through openings 56 and caused to impinge upon fan 52, thus causing the rotation of the fan. As fan 52 rotates, it aids in the circulation of the air within hood 40. As an alternative to providing a combined heater and blower unit for the dryer, the heating elements can be of an electrical type which are arranged within duct 10. With the heating elements located within duct 10, a blower need only be provided to force air along the interior of the duct in heat transferring contact with the heating elements. In this manner, the air is heated within duct 10 and then passes outwardly through ducts 24.

The dryer may be stored when not in use by removing hood 40 and swinging ducts 24 and support legs 12 into their collapsed positions as shown in FIG. 2. The hood is then folded, and duct 10 with folded ducts 24 and legs 12, heater unit 46, and hood 40, conveniently stored. When it is desired to use the dryer, legs 12 of the dryer are opened so as to cause duct 10 to be supported in its upright orientation and ducts 24 swung into their laterally projecting position. Hooks 48 may then be applied to the ducts 24 and the clothes and other material desired to be dried attached thereto. Once the clothes are in position, hood 40 is positioned over duct 10 and heater unit 46 located under duct 10. The heater unit is then started so as to cause heated air to travel upwardly through duct 16 into ducts 24 and around the clothing, in the hooded enclosure. For convenience, heater unit 46 may be provided with a timer which regulates its operating time.

It is to be understood that the invention is not to be limited to the details herein given, but may be modified within the scope of the appended claims.
