9 Claims. or. 211-5178) clothes lines stretched between hangers utilizes folding sections. for each hanger. My prior patents, Nos. 2,670,855 and 2,804,215 eliminate the necessity for a folding joint in any of the hangers while providing an entirely symmetrical structure having the desirable features inherent in using clothes lines that are parallel to each other yet which can be readily collapsed and stored.

The present invention while retaining all of the desirable functional characteristics in my prior patents provides a more compact and simplified construction which is highly economical to manufacture and assemble. The particular construction of the supporting arms affords a .sturdier support for the hangers when the clothes dryer is in the erected position and is much simpler and smoother to erect and collapse when desired.

Additionally the present invention provides improved means for attaching the clothes lines to the hangers so that they may be easily replaced when needed.

These and other objects of the invention and the various features and details of the construction and operation thereof are more fully set forth hereinafter with reference to the accompanying drawings, in which:

The present invention comprises a pair of parallel hangers between which a plurality of clothes lines are stretched. The hangers are held in position by four arms which extend radially from a collar slidably mounted on a center post or pole and actuatable longitudinally of the pole. A swivel connection affording pivotal movement about two perpendicular axes is provided between the ends of the arms and the hangers so that when the arms are pivoted into substantially parallel relationship to the center pole, the hangers swivel into a compact upright position closely adjacent the arms and the pole. In order to accomplish this, the opposite arms have similar turning action so that the arm supporting one end of the hanger is raised whereas the arm supporting the opposite en of the hanger is folded downwardly.

Strut members are pivotally connected to the center post at its upper end and are pivotally connected to the supporting arms at a point along the arm members to support the dryer in the erected position, and also to effect the desired pivotal action of the arm members when the dryer is collapsed. Accordingly, the two opposite rigid arm members, which are pivoted to a collar slidably mounted on the pole, pivot upwardly when the collar is actuated downwardly longitudinally of the pole. The other two opposite arm members are jointed to form inner and outer sections and are connected to the struts at the joint by a linkage mechanism so that when the collar is actuated downwardly, the outer sections fold downwardly about the jointed connection.

Referring now to the drawings, one form of clothes dryer made in accordance with the present invention is illustrated in Figs. 1-17 inclusive comprising a central vertical pole 1, a pair of

hangers

2 and 3 respectively and a framework 4 for supporting the hangers both in the extended and collapsed positions. When the dryer is set up for use (see Fig. 1) the

members

2 and 3 assume the spaced apart relationship shown so as to stretch between them a plurality of parallel runs of clothes line 5. In the present embodiment the

hangers

2 and 3 are tubular in form and are provided with a series of spaced apertures 6 for the reception of the clothes line 5, as will be explained in more detail hereinafter.

In accordance with the present invention, the framework 4 comprises four radially extending

arms

10, 11, 12 and 13 and four

strut members

14, 15, 16 and 17 adapted to provide vertical support for the arms 4 when the dryer is in the erected position. To this end the arms 11 and 13 which operate similarly are connected drical body portion 23a of suitable diameter to freely slide on the pole 1 and a plurality of radial projections 23b in the form of ears for pivotally supporting the inner extremity of the arm members. The arms are tu- .bular in form and may be flattened at their inner extremity to provide a face to-face contact at the pivotal connection to the ears.

Strut members

15 and 17 support arms 11 and 13 respectively and are pivotally connected at their inner ends at a fixed point on the upper extremity of the pole 1 by a collar 24 and are pivotally connected at their outer ends to the arms 11 and 13 as &

indicated at 25 and 26. As shown in Fig. 6, the body portion 24a of the collar 24 is provided with suitable apertures 27 which register with suitable apertures in the pole for reception of a

bolt

28 and 29 for immobilizing the collar 24 on the pole 1. The struts are pivotaily mounted at their inner ends between pairs of radially projecting ears 3!), 30 on the collar by a rivet 31.

The arms 16* and 12 are similar in construction and are connected at their outer extremities to the

hangers

2 and 3 by swivel joints 20a and 21a and are pivotally secured at their inner extremities to the moveable collar 23 in a manner similar to arms 11 and 13 as described above. In order to provide opposite movement of the

hangers

2 and 3 at their opposite ends, the arms and 12 are formed with -a folding joint at a point along their length, to define an inner section 10a and an outer section 10b and inner and outer sections 12a and 12b respectively.

Struts

14 and 16 support the

arms

10 and 12 and are pivotally connected at their inner ends to the fixed collar 24 and are pivotally connected by a linkage mech- .anism 40 to the

arms

10 and 12 at their jointed connection. 7 The linkage and elements comprising the jointed connection are identical and will be designated hereinafter by identical reference numerals. Referring specifically to .the arm 10, the hinged connection forming the joint of the arm 10 comprises a pair of oppositely facing

saddle members

41, 41. Each saddle member 41 is formed with an arcuate body portion 42 conforming to the contour of the arm and projecting interfitting ear portions 43 having openings 44 therein for reception of a pin 45 to permit pivotal movement of the outer section 1% with respect to ,the inner section 10a about the pin 45.

' As illustrated in Fig. 17, the opposed saddle members 41 are identical in form. To this end, one ear member 43a extends tangentially from the arcuate body portion '42 and the opposite ear member 43b is offset, so that when assembled as shown in Fig. 16, the inner-and outer sections of arm 10 are in axial alignment.

In the embodiment illustrated in Figs. l416 inclusive,

the linkage mechanism 40 comprises a pin 50 pivotally connecting the outer end of the strut 14 and the outer section 1015 of arm 10. A link 51 is pivotally connected to the strut 14 by a pin 52 at a fixed point inwardly of the pivotal connection at 50a and pivotally connected by a pin 46a to the inner section 10a of arm 10 adjacent the jointed connection. As shown in Fig. the longied in Figs. 18-21 inclusive wherein the strut 64 is pivoted vto the arm 60 through a connection affording movement ,of the strut within the plane of the inner and outer arm :sections. 60a and 60b respectively. To this end the strut I 4 64 is pivoted to the outer section 60b of the arm 60 by a pair of triangularly shaped

plates

61, 61 secured on opposite sides of the outer section 60b of arm 60 in spaced parallel relation. The strut 64 is pivotally mounted 5 intermediate the upstanding portion of the triangularly shaped plates 61, by means of a pin 62 passing through registering openings 63 in the plates and strut. A connection is provided at 65 and comprises, as shown in Fig. a pair of

links

66, 66 mounted on opposite sides of the arm and strut. The links are pivotally connected to the inner section 60a of the arm 60 by means of a pin 67 at one end and are pivotally connected to the strut by means of apin 68 at the other end at a fixed point on the strut inward of the pivotal connection to the plates. As seen by Fig. 19 the strut 64 overlies the arm so that the longitudinal axis of the strut is in vertical alignment with the longitudinal axis of the arm 60 and in a vertical plane passing through the axis of the pole 1.

In the operation of the device, the collar 23 is maintained in the elevated position shown in Figs. 1 and 2 by latch means. 70 which passes through registering apertures 71 in the pole 1. As shown, the pin 70 may be connected to the collar by a chain if desired. When the framework 4 is collapsed by removing the pin 70 and sliding the collar 23 downwardly on the pole 1, the arms 11 and 13 pivot upwardly relative to the collar 23, the

hangers

2 and 3 moving bodily inward toward the pole. Simultaneously with the upward pivotal movement of the arms 11 and 13 relative to the collar 21, the inner sections 10a and 12a of

arms

10 and 12 respectively pivot upwardly on the collar 21. The linkage and jointed connection caused the outer sections 10b and 12b to pivot about their jointed connection downwardly on the lower end of the strut 14. This effects a turning movement on the

hangers

2 and 3 as they are collapsed into an upright position substantially parallel to the pole 1. The turning movement of the

hangers

2 and 3 is made possible by the

swivel connections

20, 21, 20a and 21a. Each of the swivel connections is identical and comprises an eye bolt 80, the eye portion 81 of which encircles the hanger and is rotatable at the axis thereof. The radially projecting portion 82 is received in an opening 83 of the arm so that the arm is free to move about an axis perpendicular to the axis of a hanger. The eye bolt is maintained in the arm by means of a nut 84 secured to the outer end of the radially projecting portion 82. Suitable guide means'are provided to position the bolt 80 on the hanger in a manner to preclude longitudinal displacement with respect to the hanger. As illustrated in Fig. 9, the guide means may comprise an annular recessed indentation formed in the hanger adapted to receive the annular eye portion 81 of the eye bolt 80.

The operation of the modification illustrated in Figs. 18-21 is similar to that described above, the arms 60 being pivotedto a collar 230 which operates like the collar 23.

In order to support a plurality of clothes lines between the

hangers

2 and 3, a plurality of longitudinally spaced apertures are provided in the hangers. In the present instance, the line is formed by separate runs. The terminal end of each run is provided with abutment means which may comprise, as illustrated in Fig. 10 a collet or ferrule 90 having a diameter which readily enters the aperture 6 of the hangers. In lieu of a collet and in the interest of economy, the terminal ends may be knotted as shown at 91. A split ring or Washer 92 having its ends spaced apart and off-set to form a helical convolution isprovided which abuts the collet or knot at the outer ends. The end portions of the washer 92 are off-set an amount less than the diameter of the line to prevent the Washer from slipping off of the clothes line yet is suitable to provide for threading thereof into the apertures. In order to secure the line to the hanger, the washer 92 is turned ina clockwise direction as shown in Fig. 11 so that The latch means may comprise a pin it is threaded into. and seats behind the opening to thereby mount the line intermediate the hangers as shown in FigllZQfi 'As shown in Figs. 12 and'l'i, the washer is deformed slightly when assembled to the hanger due to the tension in the line upon erection of the dryer. This deformation prevents inadvertent disassembly of the lines from the hanger. This construction provides a simple and effective means for securing individual runs of line to intermediate the hangers which has economical and operational advantages over the prior methods wherein a single continuous line was used. When it is desired to replace an individual run when it has broken or damaged, it is only necessary to cut the run of the line at its end portion adjacent the hangers and replace it with a new run. Accordingly it is obvious that it is not necessary to replace the entire line as was required in prior apparatus when only a portion thereof is damaged.

From the foregoing, it is apparent that the present invention provides an improvement in clothes dryers of the collapsible type which is highly economical to manufactors and assemble and which is extremely efiicient and simple to operate.
