LOOP-SUPPORTING DEVICE
Abstract
A loop-supporting device is provided by an elongated handle and
a resiliently deformable, elongated frame member of generally
rectilinear configuration in its open position. A clasp is provided
for disengagably securing the frame member in closed position of
generally circular configuration, and the frame member has a
plurality of line support elements spaced along the length thereof.
With the frame member in its closed position, the loop of a line
may be supported thereby, after which the loop and frame member may
be positioned about a piling, as in a boat mooring operation.
Drawing the frame member against the piling releases the engagement
by the clasp and allows the frame member to return to its open,
generally rectilinear position. This, in turn, permits release of
the line and removal of the device with the loop remaining about
the piling.

Description
BACKGROUND OF THE INVENTION
A high level of skill (or luck) is usually required to position a
loop of a rope or line about a remote or relatively moving object
without the aid of a mechanical device. Lassoing is a frequently
employed and often frustrating technique. As will be appreciated,
the difficulty in part results from the lack of inherent rigidity
in conventional ropes and lines which, if present, would readily
enable placement in the position desired.
One area in which the problem is significant is in the mooring of
boats, and the problem has been magnified due to the increased
popularity of boating and to changes that have consequently
occurred in the manner in which the boats are moored. Previously, a
boat was customarily docked by bringing it alongside and parallel
to the wharf, in which position a crew member could easily jump
ashore and make lines fast, fore and aft; alternatively from such a
position the lines could be easily tossed to available dock
attendants. As a result of the ever-increasing scarcity of
shorefront property and the overcrowding of mooring waters, the
practice of docking vessels perpendicular to the wharves has become
popular because it permits the docking of many more craft along a
given length of pier frontage. However, this practice has
necessitated securing at least one of the lines (normally aft of
the vessel) about a piling in the water outwardly from the dock,
the accomplishment of which can prove a most difficult feat,
especially in rough or choppy waters or in high winds. Indeed,
attempting to lasso a piling under such conditions of instability
can be dangerous to personnel, and can involve even more serious
problems when the boat is being single-handed.
A number of devices have previously been suggested in the art for
use as aids in securing a rope or line about a remote object.
However, it is typical of such prior art devices that they are
quite complex in construction and operation, relatively expensive
to manufacture, and often deficient in the measure of support which
they provide for the loop.
Accordingly, it is the primary object of the present invention to
provide a novel loop-supporting device that is of relatively simply
and inexpensive construction, that provides a wholly adequate level
of support while maintaining a line loop in a desirable
configuration for placement over a remote object, and that operates
readily to effect the release of the line when desired.
It is also an object of the invention to provide a device of the
foregoing type which is constructed so as to provide a compact unit
for convenient storage and which is yet easily and speedily
assembled for use.
Another object is to provide such a device that includes other
functional elements such as a conventional boat hook, and which
possesses sufficient buoyancy for flotation and retrieval if
dropped overboard.
SUMMARY OF THE INVENTION
It has now been found that the foregoing and related objects of the
invention can be readily attained in a loop-supporting device
comprising a resiliently deformable, elongated frame member of
generally rectilinear configuration in its open position, an
elongated handle affixed to the frame member, and clasp means for
disengageably securing the frame member in a closed position
providing a generally circular configuration. The frame member has
a plurality of releasable line-support elements spaced along the
length thereof that are engageable with a line loop at a plurality
of points thereabout to maintain the loop in an open position with
the frame member in the closed position providing the generally
circular configuration thereof. The line is releasable from the
line support elements upon disengagement of the clasp means and
return of the frame member to its open position.
In the preferred device the support elements on the frame member
comprise a multiplicity of spring-biased clips, under which the
line is engageable, and the clasp means is on the frame member
adjacent one end thereof. In such a device, the other end of the
frame member is frictionally retained by the clasp means to
maintain the frame member in the generally circular configuration
thereof.
The frame member and handle are desirably disengageable from one
another, and the handle may have a transverse channel extending
across one end thereof that is dimensioned and configured for
seating of a portion of the frame member therein. A retaining
member that is disengageably securable on the channelled end of the
handle is used to secure the frame portion against relative
rotation in the channel of the handle. Most desirably, the handle
has a hollow portion providing a cavity therein that opens at the
channelled end thereof, and that is dimensioned and configured to
house the frame member. The retaining member employed in such a
structure is appropriately a cap releasably engaged upon the end of
the handle to close the cavity therein. It is especially preferred
that the handle be tubular and that the end thereof at which the
cavity opens be threaded. A cap with a generally cylindrical
cooperatively threaded sidewall is threadably engaged upon the end
of the handle and the cap has an end wall with a pin extending
coaxially beyond the sidewall thereof. The frame portion in such a
case is provided with an aperture through which the pin extends to
substantially prevent relative transverse movement between the
handle and frame member.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT
Turning now in detail to FIGS. 1-4 of the drawings, therein
illustrated is a loop-supporting device embodying the present
invention and consisting of a handle or pole, generally designated
by the numeral 10, and a frame member generally designated by the
numeral 12. The pole 10 comprises a generally hollow tubular body
portion 14 that has a mooring or boat hook 16 of conventional
design affixed to one end, and a knurled cap 18 disengageably
secured upon the opposite end thereof.
In the normally open position illustrated in FIG. 2, the frame
member 12 is of rectilinear configuration and may be stored in a
cavity 19 within the handle 14. Conveniently, the cavity 19 is
defined in the body 14 between the disengageable cap 18 and the
core spacer 20 which is rigidly affixed within the body 14
intermediate the ends thereof. The frame member 12 consists of a
length or strap 22 of resiliently deformable material such as
spring steel, and secured thereto at spaced locations along the
length thereof are a multiplicity of line clips 24. A buckle 26 of
generally rectangular cross section has one side secured in a
channel defined by a reversely bent portion 28 at one end of the
strap 22. The buckle 26 is dimensioned to provide a space between
its opposite side and the outer side of the strap 22, in which
space the tongue portion 30 provided by the opposite end of the
strap 22 is received and frictionally engaged. A small aperture 32
is provided in the strap 22 at an intermediate location for a
purpose to be more fully explained hereinafter.
A diametrically extending slot 34 is cut or otherwise formed in the
open or hollow end of the pole 10, onto which is secured the cap
18. The slot 34 is dimensioned to snugly seat the width of the
strap 22, and the end portion of the body 14 is provided with
external threads 36 that threadably engage with the internal
threads 38 on the sidewall of the cap 18. The cap 18 has a pin or
stud 40 projecting axially from the end wall thereof and the pin 40
extends outwardly of the sidewall to pass through the aperture 32
in the strap 22 when assembled therewith.
As will now be apparent, the pole 10 and frame member 12 are
assembled by seating the strap 22 within the slot 34 with the
aperture 32 thereof aligned with the axis of the pole body 14.
Threadably engaging the cap 18 on the body 14 clamps the strap 22
against the body 14 to prevent relative axial and rotational
movement, and engagement of the pin 40 in the aperture 32 prevents
transverse movement of the strap 22 in the slot 34.
Operation of the device is readily illustrated by reference to
FIGS. 5 and 6. As can be seen, the tongue 30 of the strap 22 of the
frame member 12 is frictionally engaged within the buckle 26 to
secure the ends of the strap 22 together in the closed position
thereof, providing a generally circular configuration. With the
strap 22 so configured, the loop of a mooring line 44 is
disengageably secured therein at several points under the retaining
lips 42 of the line clips 24, thus supporting the loop in an open
configuration. With the line 44 so arranged within the frame member
12, the frame member 12 and the loop of the line 44 are brought
downwardly about a piling 46 or other mooring post, and thereafter
the handle is pulled sharply towards the operator to cause the far
end of the frame member 12 to strike the piling. The force exerted
overcomes the frictional resistance between the buckle 26 and
tongue 30, causing the release of the tongue 30 and permitting
return of the frame member 12 to its open position in which it is
generally rectilinear. The resultant relative movement occurring
between the line 44 and the frame member 12 pulls the line 44 from
the line clips 24, allowing removal of the device with the line 44
remaining encircled about the piling 46.
Various resiliently-deformable materials may be used to provide the
frame member, including metal, fiberglass reinforced plastics,
polyamides, polyolefins and polycarbonates; generally, the strap
and the clips that are provided at spaced locations along the
length thereof are conveniently and desirably provided by an
appropriately resilient metal. The clips may be spot welded or
otherwise bonded to the strap, and a simple loop of metal or
plastic clamped adjacent one end of the strap may serve as the
buckle under which the opposite end of the strap may be inserted
and frictionally retained.
Spring biased clips of the simple construction illustrated are
preferred as the support elements for the loop since they provide
secure engagement of the line when desired and readily release it
during opening of the frame member. While both simpler and more
complex types of support elements may be used, spring biasing is
desirable and effective to provide secure engagement of the line
and is readily attained in the construction shown. Fewer than four
support elements (as illustrated) may be feasible, but is less
desirable from the standpoint of holding the loop in an adequately
opened position commensurate with a small diameter frame member.
Conversely, more than four support elements may be employed but are
not necessary.
Although the illustrated embodiment is especially desirable from
the standpoint of providing a compact structure which may quickly
and readily be assembled prior to use for mooring, and which has
the added advantage of providing sufficient buoyancy for flotation,
it is not essential to the attainment of the objectives of the
invention that the device be disassembable or that the frame member
be housed within the handle when not in use. Moreover, the manner
in which the several disengageable parts are assembled may vary
considerably from that illustrated and discussed hereinabove.
Furthermore, although the handle of the device is desirably
constructed to include a mooring or boat hook upon the opposite end
thereof, this is not essential to the invention and may, in fact,
be quite inappropriate when the device is intended for non-marine
applications.
The choice of materials for the non-resilient parts will depend to
a degree upon the intended use for the device and should not be
considered to limit the scope of the invention. In most cases, the
pole and associated elements will desirably be constructed of a
lightweight material such as aluminum, or synthetic plastic for
ease in handling and buoyancy, but heavier materials such as wood
may also be used. Parts other than those shown in the drawings may
be employed if necessary or desirable, and in the illustrated
tubular pole construction gaskets and the like will desirably be
employed to prevent leakage.
By the use herein of the term "generally rectilinear" to describe
the configuration of the frame member in the open position, it is
intended that somewhat curvilinear configurations also be
encompassed, as is shown in phantom line in FIG. 6. Although
stricter rectilinearity is preferred to enable the frame member to
be readily inserted and removed from the handle cavity,
substantially any relatively open configuration may be
feasible.
Thus, it can be seen that the present invention provides a novel
loop-supporting device that is of relatively simple and inexpensive
construction, that provides a wholly adequate level of support
while maintaining a line loop in a desirable configuration for
placement over a remote object, and that operates readily to effect
the release of the line when desired. The device may be constructed
so as to provide a compact unit for convenient storage which is
easily and speedily assembled for use. Moreover, the device of the
invention may include other functional elements such as a
conventional boat hook, and it may possess sufficient buoyancy for
flotation and retrieval if dropped overboard.
