Description

2355487 CLOTHESLINE SYSTEM WITH A SUPPORT SYS EM AND IMPROVED CLOTHESPINS

FIELD OF THE INVENTI

The present invention relates to a clothesline system that can automatically secure clothes onto a main clothes cable without having to manually do so with clothespins.

A distinguishing feature of the clothesline system resides in the provision of a support member that prevents the main cable from sagging beyond a predetermined distance from a secondary cable while under the' effect of the clothes weight. The secondary clothes cable comprises improved clothespins that can be used with the clothesline system to engage the main cable and that feature multiple clothes holding positions. The invention also extends to a cable connector element that allows one section of a continuous cable to form the main cable and a second section of the continuous cable to form the secondary cable. As a result, the main cable is continuous with the secondary cable.

BACKGROUND OF THE INVENTI

2t Typical clothesline systems provide a support on which wet clothes are placed to dry. The clothesline system includes a continuous cable that extends between two pulleys. The cable provides the support on which to hang the wet clothes and in order to secure clothes onto the cable, clothespins must be manually placed 'thereon.

These clothespins must be manually removed and stored when the clothes are dry and ready to be removed from the clothesline system.

To overcome the cumbersome operation of manually inserting and removing each clothespin, U.S. patent 4,519,509 issued on May 28, 1985, provides a means for automatically presenting clothespins onto the clothes cable to secure the clothes and a means for automatically removing the clothespins from the dry clothes. The clothesline system as disclosed in this reference includes an endless main cable extending between two pulleys. A pin lay wheel located between the two pulleys has a number of V-shaped recesses for receiving a series of clothespins on a secondary cable that engage the main cable while in a normally closed position. The ends of the secondary cable are attached to the main cable and when the main cable is displaced the secondary cable is moved in unison to bring the pins secured thereon in engagement with the pin lay wheel. The pins are automatically opened thus releasing the main cable which allows them to travel over an arched path def ined by the periphery of the lay wheel.

Further rotation of the main cable causes the pins to reengage a run of the main cable on which wet articles of clothing are placed. As a result, the articles of clothing are secured on the main cable.

Although the system facilitates securing the clothes onto the clothesline system, it fails to provide' a means for preventing the main cable from sagging beyond an acceptable range within which the pins can engage the cable and secure the clothes that are placed to dry. More specifically, upon placing clothes onto the main cable, the main cable will tend to accordingly pull away from the secondary cable. In some instances, however the clothes will pull the main cable under the effect of gravity at an appreciable distance from the secondary cable which will place it beyond a distance within which a pin can engage the main cable. Moreover, the clothespins described in this reference are designed,with only one clothes holding position, thus limiting the range within which the clothes cable may sag away from the secondary cable.

Thus there is a need in the industry to provide a clothesline system with a support system that maintains the distance between the main cable and the cable within an acceptable range. In addition, there is a need to provide clothespins with multiple clothes holding. positions for successfully engaging articles of clothing placed over the main cable.

OBJECTIVES AND STATEMENT OF THE INVENTIO

It is an object of the invention to provide a clothesline system with a support member capable of maintaining the main cable within an acceptable range from the secondary cable.

It is a further object of the invention to provide clothespins for use with a clothesline system that are capable of multiple clothes holding positions.

It is another object of the invention to provide a clothesline system wherein the main cable is continuous with the secondary cable.

It is another object of the invention to provide a novel cable connector element capable of establishing one section of a continuous cable as the main cable and a second section of the same continuous cable as the secondary-cable.

In a preferred embodiment, the clothesline system comprises a main clothes cable that extends between two spaced apart pulleys. The cable has an upper run and a lower run. A support member being located between the two runs includes an upper support arm and a lower support arm. A clothespin lay wheel is mounted at the extremity of the upper support arm so that it is in the plane of the 4 two runs. The lay wheel has a V-shaped recess to receive- a secondary cable on which is attached a series of clothespins. The clothespins engage the main cable in a normally closed position. The ends of the secondary cable are attached to the main cable so as to move in unison with the main cable. Upon rotation of the main cable, the closed pins register with the recess of the sprocket wheel and automatically open. Thus, the clothespins release the main cable and travel along an arched path defined by the periphery of the lay wheel. Further rotation of the main cable causes the clothespin to re-engage the run of the main cable on which articles of clothing are placed.

Advantageously, the support member will prevent the main cable from deflecting beyond the distance within which the is clothespins can successfully engage the main cable at different holding positions.

In the realization described above, the secondary cable is a separate cable attached to the main cable. In a variant, the main cable and the secondary cable are continuous with one another. A cable connector element establishes one section of a continuous cable to form the main cable and a second section of the same continuous cable to form the secondary cable.

DESCRIPTION OF A PREFERRED --- EMBODIMENT

Referring now to the drawings, figure I illustrates a clothesline system 4 on which articles of clothing 6 are placed to dry. Broadly stated, the clothesline includes.

a main cable 10 sul5ported between two spaced apart pulleys 14 and 16 and a support member 30 to which pulley 14 is mounted. A pin lay wheel 60, also mounted to the support member 30, is provided to deposit clothespin 80, which are attached to a secondary cable 70, onto articles of clothing 6 that may be placed on the main cable 10.

The main cable 10 is a continuous cable whose ends are attached to establish two continuous runs 12 between pulleys 14 and 16, namely a lower run 121 and an upper run 12". Pulley 14 is rotatably mounted to support member 30.

which in turn is attached to a bracket 17 that is pivotally attached to a support structure 23. Pulley 16 is rotatably mounted to bracket 18 that is pivotally attached to support structure 24 that is at a spaced apart.

distance from support structure 23.

As best seen in f igure 2, the support member 30 comprises apertures 32 through both of its side walls to__ receive a pin which establishes the pivotal aLxis for pulley 14 and serves to secure bracket 17 that provides a connection point with support structure 23. A recess 34 provided between the walls on which apertures 32 are formed, receives pulley 14 and allows it to rotate freely therein.

The support member 30 includes two distinct reinforced arms that originate at.the side walls between which pulley 14 is mounted, namely, a lower support arm 36 and - an ' upper support arm 48. The lower support arm 36 includes three continuous segments: a first oblique segment which extends beyond pulley 14 and run 121, a second horizontal intermediate segment which extends parallel to the cable's tangential axis with pulley 14 and a final segment that extends upward tangential to pin lay wheel 60 to be described later. A guide 38 is provided at the extreme end of the third segment to receive cable lo and support it along an axis that is tangent to that of pulley 14. The guide 38 includes to mating components that when fastened with screws 40 and 42 provide a channel through which cable 10 can slide freely. In effect, the lower support arm 36 provides support along a span 11 of run 121 on which clothes 6 may be freely placed. This span 11 extends closely to the pin lay wheel 60.

The upper support arm 48 also includes three 8 continuous segments; a first extending beyond pulley 14 and run 1211, a second extending along run 1211 and a final segment extending between runs 121 and 1211, passed the extremity of guide 38. A guide member 51 projects beyond S the surface of the second segment and includes an aperture through which cable 10 extends and can slide freely. The guide member 51 maintains the cable 10 along the outer surface of the second segment of support arm 48 so as to direct it onto a bearing 50 that provides a rolling contact surface guiding cable 10 toward the pulley.14.

The third segment of the upper support arm 48 is a fork 52 that supports pin lay wheel 60. The fork 52 includes two parallel spaced apart members, each with respective apertures 54 through which a pin 56 is inserted to rotatably support the pin lay wheel 60 which is preferably the same diameter as pulleys 14 and 16. The f ork 52 orients pin lay wheel 60 in the plane defined by pulleys 14 and 16 at a distance relatively close to run 121.

Pin lay wheel 60 includes a circumferential groove 63 with two radially projecting side walls 64. The s i de walls 64 progressively widen radially outward to receive therebetween and progressively open a series of normally closed pins 80 that are carried by a secondary cable 7o 2S and whose ends 65 are attached to the main cable 10 by means well known to those skilled in the art. In this embodiment, the secondary cable 70 is a separate cable from the main cable 10.

9 As best illustrated in figures 3 and 4, each__ clothespin 80 comprises -three parts, namely, a head 82, a neck 84 and a body 86. Head 82 is a hook conf igured member that can be frictionally attached onto the secondary cable 70. The head is resilient so it can be readily detached from the secondary cable 70 if desired.

The ability to readily remove and install the head is convenient because the clothespins 80 may be installed after the clothesline system has been assembled. This also allows to place a desired number of clothespins 80 anywhere along the secondary cable, contrary to the system disclosed in the previously referred patent where the pins are not removable. The neck 84 is a linear member that connects head 82 with body 86 so as to support the latter on the secondary cable 70. The body 86 is a flat jaw like member having two legs 88 and 90 that are pivotally connected by a hinge area 91. The hinge area def ines a cavity 92 around neck 84 that extends f rom one leg to the other. A C-shaped spring biasing member 94.urges legs 88 and 90 to close, such that tips 96 of each leg abut one another. The inner surfaces of the legs that face one another below the hinge area 91 and above tips.96 provide a channel 99 within which multiple holding positions of cable 10 (including articles of clothing thereon) are possible relative the hinge area 91. The channel 99 includes a plurality of recesses 98 for selectively receiving the main cable - 10 at different holding positions. In a variant, the channel 99 can be - substantially of uniform width while still providing_ multiple holding positions for cable jo. The' channel establishes the acceptable distance within which the main cable 10 can sag while being engageable by the clothespin 80. Upon engaging the cable 10 and closing channel 99, the cable is held in one of different holding positions from the hinge area 91. A support 100 provides a top wall against which the main cable 10 or clothes 6 can abut upon entering channel 99. Accordingly, the top wall support i0o maintains a minimum clearance between the main cable and the secondary cable 70.

As the main cable 10 is manually pulled, secondary cable 70 attached to the main cable 10 is caused to move in the same direction. As best seen in f igure 5, the head 82 of each clothespin 80 subsequently registers in groove 63 of pin lay wheel 60 and draws body 86 radially inward along the side walls 64 of the wheel. As pins 80 enter between the side walls 64 of pin lay wheel 60, pressure is progressively applied on the upper extremity 95 of legs 88 and 90 which causes them to pivot on the hinge area.91 and accordingly pivot abutting tips 96 apart, thus opening channel 99.. As best illustrated in figure 1, the opened clothespins So disengage themselves from the main cable 10 and move along the arched path def ined by the pin -lay wheel 60. Upon further rotation of the main cable 10, the pin is brought toward run 121 such that cable.10 enters the opened cavity 99 while tips 96 are still apart. In accordance with the invention, support arm 30 will preventthe main cable 10 from sagging beyond theacceptable distance within which the clothespins 80 can successfully engage the main cable 10 at different holding positions along channel 99. The clothespins So and support member are preferably manufactured by injection moulding and are reinforced by fibres.

In operation, to dry clothes on clothesline system 4, articles of clothing 6 are respectively placed over the supported span 11 of run 121. As illustrated in figure 6, the main clothes cable 10 is then pulled in a direction shown by the arrow which respectively causes secondary cable 70 to carry clothespins 80 along the arched path def ined by- the pin lay wheel 60. Accordingly,. the clothespins automatically open to release cable 10 of run 1211 and re-engage cable 10 of run 121. Upon exiting the pin lay wheel 60 the clothespins 80 are automatically closed over cable 10 and secure respective articles of 'clothing 6 placed on run 121 at one of several possible holding positions provided along channel 99 as seen in figure 7.

When the clothes are dry, the main cable 10 is pulled in the opposite direction so as to release clothespins Bo that secure the articles of clothing 6 along run 121.

More specifically, secondary cable 70 which moves in unison with the main cable 10, carries the clothespin 80 12 along the path defined by pin lay wheel 60 which causes the pins to automaticalfy open, thus disengaging'from the article of clothing 6 on run 12, and thus engaging main cable 10 of run 12".

In the above description, the secondary cable 70 is a separate cable that is attached to the main cable to form a synchronized structure. In a variant, the main cable 10 and the secondary cable 70 are continuous with one another. Two cable connector elements 1101 and lion allow one section of a continuous cable 8 to form the main cable 10 and a second section of the continuous cable 8 to form the secondary cable 70.

The clothesline system 4 as illustrated in figure 8 comprises all the structure arid functional elements as described above with the addition of two novel cable connector elements 1101 and 110". As best illustrated in figure 9 each cable connector 110 includes two mating plates 112 and 116. Generally stated, plate 112 comprises outer walls 122, partition walls 124, support posts 126.

and apertures 128a, 128b, and 128c. The outer walls 122 define the shape of the plate which in this particular case is a square body with a pointed extension at one of its sides. The partition walls 124 are provided within the boundary established by walls 122 to define a cavit) for receiving one end of the continuous cable 8 and a channel 132 for engaging a segment of the continuous cable 8. The partition walls provide. a number of projections 132 for pricking the continuous cable 8 at various locations along channel 132 and at the entrance to cavity to secure the cable therein. Apertures 128 are provided on walls 122 to allow cable 8 to enter cavity 130 and channel 132 while the two plates 112 and 116 are secured thereon. More specifically, aperture 128a communicates with cavity 130 while - 128b and 128c communicate with channel 132. Plate 116 is a flat member that is identical in shape to plate 112... It includes three apertures 118 that align with support posts 126. of plate 112 that provide an aperture through which screws 114 are threadedly engaged to fasten the two plates 112 and 116 together. Accordingly, the end of the continuous cable 8 that extends through aperture 128a is secured into cavity 130 while the segment of the continuous cable that extends between apertures 128b and 128c are secured within channel 132.

As best illustrated in figure 10, the two cable connector elements 1101 and 11011 create two cable runs from one-continuous cable 8, namely the main cable 10 and the secondary cable 70. More specifically, the main cable is defined as the section of the continuous cable 8 whose end is secured within cavity 130 of connector element. 11011 and extends out through aperture 128a, along pulley 14, passes through channel 132 of connector element 1101, passes over pulley 16 and extends into aperture. 128b - 14 of connector element 110". The remaining portion of the continuous cable 8 defiiies the secondary cable 70. More particularly, the secondary cable 70 is the section of the continuous cable 8 extending from aperture 128c, travelling along the periphery of pin lay wheel 60 and whose end is secured into cavity 130 of cable connector element 1101.

The above description of the preferred embodiment should not be interpreted in any limiting manner since variations and.refinements are possible which are within the spirit and scope of the present invention. The scope of the invention is defined in the appended claims and their equivalents.
