OUTDOOR CLOTHES DRYER 2 Sheets-Sheet 2 Filed June 4, 1958 INVENTOR Bmd, M flu/fd ATTORNEY United States Patent O OUTDOOR CLOTHES DRYER Robert W. Schweyer, Emmaus, Pa.

Application June 4, 1958, Serial No. 739,906 9 Claims. (Cl. 211-178) This invention relates to a collapsible clothes dryer of the umbrella type such as generally exemplied inv the United States patents to Midouhas 2,459,110, of January ll, 1949, and to Hagar 2,802,579, of August 13, 1957.

In such dryers opposed pairs of radial arms extending from opposite sides of a central supporting standard carry between their free ends horizontal relatively parallel clothes line supports between which are strung a plurality of parallel lines. Such dryers are customarily collapsible by swinging of their radial arms in vertical planes into substantial parallelism with each other and with the central standard. This has necessitated elther that the parallel line supports be composed of pivotally connected sections with inherent weakness, complexity, andincreased expense, or else has required that the two supporting arms of each pair be arranged to collapse in opposite vertical directions, the unitary support in each case being permanently universally connected to the free ends of these arms. This latter arrangement has involved a somewhat complicated construction and operation and the geometric arrangement of the parts has imposed certain undesired limitations on the proportions of the respective parts.

It is accordingly a primary object of the present invention to provide an improved dryer of the above type which permits use of completely rigid unitary line supports in conjunction with a more or less standard supporting structure radial supporting arms, all of which are swingable vertically in the same direction to erect or collapse the dryer.

To this end each such support is universally connected to one of its supporting arms and is detachably connected to the other said arm whereby in the collapsed condition of the dryer it may be swung about its universal connection into substantial parallelism with the standard and the various supporting arms and, as an incident to erection of the dryer, the said detachable connection between theline support and its said other arm is automatically established.

A particularly novel feature of the invention consists in the structure of the detachable connection which comprises a hook appropriately positioned on the support for engagement with a cooperating eyelet carried at the free end of its other said arm. For guiding the hook automatically through and into operative engagement with the eyelet, the free end of the hook has connected thereto a exible tension element which is slidably threaded through the eyelet and then connected either to the central standard or some other portion of the dryer, such as another arm thereof, with respect to which the eyelet bearing arm recedes during its movement to operative position. The arrangement is such that the movement of thefree end of the arm bearing the eyelet will draw the flexibletensionelement substantially taut thereby guiding the free end of the hook toward and through the eyelet as the arms are swung to fully erectedl operative position.

"ice

Conversely, `the foregoing arrangement will result in automatic withdrawal of the hook from' its eyelet incident to collapsing of the device and the slackening of the vtension element incident to such collapsing will pervmit.,downward swinging of the support about its universalconnection to a position in substantial parallelism Withthe collapsed arms and other members of the structure.y rhis will obviously facilitate storage, packaging ,and shipping ofthe dryers in fully assembled condition.

.A.device exemplifying the preferred embodiment of -my ,invention is illustrated in the accompanying drawings in which:

Fig. lrepresents a plan View of a clothes dryer constructed in accordance with the invention, the dryer being in its erected ,operative condition;

lFig. 2 a front elevationY of the dryer shown in Fig. 1, the central'supporting standard being shown but fragmentarily;

Fig. 3 a front elevation similar to Pig. 2 but with the dryer in a substantially collapsed condition preparatory to storage; l

A an enlarged detail section on the line 4-4 of Fig. 5 an .enlarged fragmentary elevation of the de- `tachable connection between oneof the supporting arms audits associated line support, same being taken on the .line-S-S ofFig. 6; and

aplan view partlyinsection showing the detachable connection of Fig. 5.

Referringnowin detail .tothe accompanying drawings, the structure of the main portion of the device shown is largelyconventional. Such device comprises a central .preferably tubular supporting standard 10 which will normallyhave its lower end, not shown, supported 1n a ,vertical socket or .otherwise supported in upright generallyvertical position.

Vertically slideably disposed about the standard-10 is an annular collar 12 most clearly illustrated in Fig. 4 having suitably arranged brackets orclevises 13 within lwhich are pivoted at 14 the inner ends of a plurality of armslS and 16. rhese arms are arranged in pairs 1S- 41.5 and 16-16, the armsof each pair being in relatively dlverging relation from their pivotal connections 14 to the collar VMaud post or standard 10. It will be seen that the respective pairsfof arms 15-15 and 16--16 are arranged in symmetrical relation on opposite sides of the vertical standard 1i) and the'arms are swingable about ltheir respective pivots `lil. in vertical planes which radiate fromthe major vertical axis of the `standard 10.

Fortlie purpose of raising and lowering the arms 15, -16 automatically incident to raising or lowering of the collarl there is provided in association with each such arm a rigid link 117 pivoted to the mid-section of said arm asat 18, and also pivotally connected at 19 to a clevis V2t) carried by a collar -21 xed at the upper end of the standard 16.

Carried at the free ends of the arms 15-15 and 16- 16 of each pair is a rigid rectilinearrope support 22. It willbe seen that these rope supports 22. `are disposed horizontally and in relatively spaced parallel relation to each other in the erected operative position of the dryer, wherebya plurality of relatively parallel clothes line segments L may -be strung between them in usual manner as is indi- Vcated in Fig. l.

theerected condition of the device is substantially as disclosedvin the Midouhas patent, above mentioned, except that lthe supports 22 are each of rigid construction throughout and are associated with their respective arms for erection and collapsing in a novel and highly useful manner, as willhereinafter appear.

Since'the respective rope supports 22 are Vsupported by and coact Vwith their respective pairs of arms 15-15 and .i6-'16m identical manner it will A sufice to describe in detail only the construction and operation of the support carried by the arms 1'5-15. It will be seen by reference to Figs.V 2 and V3 that adjacent one end Vthe support 22 is universally lconnected to the Afree end of one arm 15,

the universal connection preferably being of the permanent type and exemplied by the two eyelet bolts 23 and 24 having their eyelets interconnected in usual manner.

YFlhe stem'23 of the bolt 23 is preferably rotatably secured in the free end portion of its associated arm`15 and Ysimilarly the stern of `the bolt 24 is rotatably secured in its associated support 22, such rotatable association of the bolt stems with their associated arm and support refspectively contributing to the universal movement thus determined in the preferred embodiment by abutment between the collar 12 and the anged sleeves or bushings 28. As the collar 12 moves downwardly it will be seen that the arms 15 and 16 after they have passed their dead center portion are caused to swing 'upwardly by action of the links 17. The movement toward each other of the free ends of each pair of arms will automatically disengage the hooks 26 from the eyelets 25 permitting the one end of each supportr22V to drop free so that it may swing downwardly about its permanenti'universal conneeton Under' theaction of gravity the supports 22 and their associated clothes lines L will yassume a position substantially as'shown in Fig. 3 and where the dryer structure is to be completely collapsed it is necessary-then only to manually swing the supports 22 about their universal connections into substantial parallelism with the respective collapsed arms 15 and 16 and the standardlt). It will be seen that in the collapsed condidepending therefrom is an eyelet which is arranged for coaction with a hook 26 iixed on the support 22 to Y provide an automatically establishable and disengageable connection incident to the erection and collapsing of the dryer.

' It will be seen that-the hook 26, as best shownin Figs.

' 5 and 6, has its free end operative portion 26a extending generally parallel to the support 22 and toward the eyelets 23 and 24. Thus in the position shown in Fig. 2

' the free end 26a of the hook will be operatively received through the eyelet 25. It willV further be apparent that as the arms 15--15 are swung vertically toward collapsed position and after they have passed their dead center 'position wherein their free ends are the same` level as the collar 13 their free ends will tend to approach each 24 will move the support 22 endwise or to the right in Fig. 2 to disengage the hook portion 26a from the eyelet 25.

YFor thepurpose of automatically reinserting the hook portion 26a through the eyelet25 and for raising the x support 22 about its universal connection 23-24 to perinit this, incident to erection of the dryer, there .is provideda tension or guide element 27, preferably in the form of a exible metal cable which is secured to the freeend of the hook portion 26a. In theform shown,

' the cableV 27 extends into and is iixedly secured within a socket, not shown, in the free end of the hook portion 26a. From the free end 26a of the hook the element 27 extends and is connected to the central supporting standard 1 0. In the preferred embodiment of the invention there is employed but a single such element or cable 27 which extends through diametrically opposed openings in the central standard 10 and has its opposite 'ends connected to the respective hooks 26 of the two supports 22. If the ends of la common cable 27 are thus to be con- ;inected to the respective hooks 26 associated with the opposite pairs of arms 15-15 and 16--16, it is not essential that the cable 27 thus extend through the standard 10 Vnor that it be secured thereto in any way, though this is'desirable in order that the cable may extend radially and generally parallel to its associated arms 15, 16 and thus be disposed in an out-of-the-way position. In the embodiment of the invention illustrated the said cable 27 -ilanged ends in abutment with the standard.

In the operation of the invention, in order to collapse -the dryer from its erected position, as shown in Figs. l

and 2, the collar 12 is manually urged downwardly about the standard Y10 from its uppermost position, which is -operative position. l

tion of the devicethe tension element 27 becomes slack to facilitate the downward swinging of thel supports 22 but the tension element, nevertheless is slidably threaded rthrough the eyelet 25 ofthe respective pairs of arms 15-15 and 16-16. Thus, upon subsequent erection of fthe device as the element 27 Vis drawn substantially taut through the eyelet 25 it will serve both to guide the hook end 26a into said eyelet and to pull itV therethrough into It is believed to be apparentVv from the .foregoing that I have conceived a clothes dryer structure of the collapsible v p unitary and completely rigid construction. Y
