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
″. As best illustrated in
FIG. 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
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
10
is defined as the section of the continuous cable
8
whose end is secured within cavity
130
of connector element
110
″ and extends out through aperture
128
a
, along pulley
14
, passes through channel
132
of connector element
110
′, passes over pulley
16
and extends into aperture
128
b
of connector element
110
″. The remaining portion of the continuous cable
8
defines the secondary cable
70
. More particularly, the secondary cable
70
is the section of the continuous cable
8
extending from aperture
128
c
, travelling along the periphery of pin lay wheel
60
and whose end is secured into cavity
130
of cable connector element
110
