Abstract
A clothesline system is provided for automatically applying clothespins to articles to be dried once they are placed on a clothesline. The clothesline system comprises first and second pulleys, which are positioned at a spaced apart distance from each other, as well as a main cable, a secondary cable and a plurality of clothespins. The clothespins are capable of being removably attached to the secondary cable, and are movable between an open and closed position for receiving and gripping articles to be dried to the main cable. The clothesline system further comprises a mechanism for automatically opening and closing the clothespins so that they are able to either selectively grip or release the articles to be dried. Finally, the clothesline system comprises a support system for guiding and supporting the main cable such that the main cable is prevented from sagging beyond an acceptable distance within which the clothespins are capable of being attached to the main cable.
Description




FIELD OF THE INVENTION




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 wit 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 INVENTION




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 see 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. Pat. No. 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 defined 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 secondary 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 INVENTION




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 on 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 at 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 two runs. The lay wheel has a V-shaped recess to receive a secondary cable on which is attained 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 closeting are placed. Advantageously, the support member will prevent the main cable from deflecting beyond the distance within which the 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,

FIG. 1

illustrates a clothesline system


4


on which articles of clothing


6


are placed to dry. Broadly stated, the clothesline includes a main cable


10


supported 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 between pulleys


14


and


16


, namely a lower run


12


′ 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

FIG. 2

, the support member


30


comprises apertures


32


through both of its side walls to receive a pin which establishes the pivotal axis 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


12


′, 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


10


and support it along an axis that is tangent to that of pulley


14


. The guide


38


includes two 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


12


′ 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 continuous segments; a first oblique segment extending beyond pulley


14


and guiding run


12


″, a second segment extending along run


12


″ and a final segment extending between runs


12


′ and


12


″, past the extremity of guide


38


. A guide member


51


projects beyond 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


, shown in

FIG. 5

, is inserted to rotatably support the pin lay wheel


60


which is preferably the same diameter as pulleys


14


and


16


. The fork


52


orients pin lay wheel


60


in the plane defined by pulleys


14


and


16


at a distance relatively close to run


12


′.




Pin lay wheel


60


includes a circumferential groove


63


with two radially projecting side wall


64


. The side 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


70


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


.




As best illustrated in

FIGS. 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 configured 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 defines a cavity


92


around neck


84


that extends from 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 leas 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


10


. 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


100


maintains a minimum clearance between the main cable


10


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

FIG. 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

FIG. 1

, the opened clothespins


80


disengage themselves from the main cable


10


, the pin is brought toward run


12


′ such that cable


10


enters the opened cavity


99


while tips


96


are still apart. In accordance with the invention, support arm


36


will prevent the main cable


10


from sagging beyond the acceptable distance within which the clothespins


80


can successfully engage the main cable


10


at different holding positions along channel


99


. The clothespins


80


and support member


30


are preferably manufactured by injection moulding and are reinforced by fibers.




In operation, to dry clothes on clothesline system


4


, articles of clothing


6


are respectively placed over the supported span


11


of run


12


′. As illustrated in

FIG. 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


alone the arched path defined by the pin lay wheel


60


. Accordingly, the clothespins automatically open to release cable


10


of run


12


″ and re-engage cable


10


of run


12


′. 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


12


′ at one of several possible holding positions provided along channel


99


as seen in FIG.


7


.




When the clothes are dry, the main cable


10


is pulled in the opposite direction so as to release clothespins


80


that secure the articles of clothing


6


along run


12


′. More specifically, secondary cable


70


which moves in unison with the main cable


10


, carries the clothespin


80


along the path defined by pin lay wheel


60


which causes the pins to automatically 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


110


′ and


110


″ 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

FIG. 8

comprises all the structure and functional elements as described above with the addition of two novel cable connector elements


110


′ and


110

126


and apertures


128




a


,


128




b


and


128




c


. 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 cavity


130


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 for pricking the continuous cable


8


at various locations along channel


132


and at the entrance to cavity


130


to secure the cable therein. Apertures 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


128




a


communicates with cavity


130


while


128




b


and


128




c


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


128




a


is secured into cavity


130


while the segment of the continuous cable that extends between apertures


128




b


and


128




c


are secured within channel


132


.




As best illustrated in

FIG. 10

, the two cable connector elements


110


′ and


110


″ create two cable runs from one continuous cable


8


, namely the main cable


10


and the secondary cable


70


. More specifically, the main cable
