Abstract
A flat oblong piece of brightly colored, durable, stretchable elastomeric material has a pair of apertures spaced by approximately 2″ less than the outermost reaches of the cleat arms. The visual guard may be stretched over the arms of the cleat and provides a visual warning to passersby without interfering with the function of the cleat: a rope may be attached above or below the guard without inhibiting its function.
Description
BACKGROUND AND SUMMARY OF THE INVENTION
The present invention is directed to a visual guard for a dock cleat that does not interfere with its use, allowing a rope to be attached either above or below the guard.
Docks are equipped with cleats to permit boats to be tied off by securing a rope thereto. The cleat, whether or not it has a rope attached, is a danger to a pedestrian walking along the dock. In addition to the physical harm to the walker's toe or foot, the cleat can cause the pedestrian to lose her/his balance and possibly fall in the water.
Several attempts have been made to try to solve this problem. For example, Silvia (U.S. Pat. No. 4,685,500), Kress (U.S. Pat. No. 5,327,844), and Havnaer, Jr. (U.S. Pat. No. 5,826,531) provide cleat covers. Each of these patents provides an elastomeric cover whose purpose is to prevent physical contact with the dock cleat. They each provide some means to accommodate a rope which has been attached to the cleat. The problem is, that should a person desire to tie/untie a boat to/from the cleat, it is necessary to remove the cover. The cleat cover can then become windblown, forgotten, or otherwise misplaced rather than replaced and the result is the dock cleat continues to be a potential threat to a person walking on the dock. Further, these designs are large since they cover the entire cleat and are comparatively complicated to manufacture with a resultant impact on cost.
The present invention provides an elegantly simple device to provide, primarily, visual protection to a passerby. The cleat guard of the present invention comprises an oblong, flat piece of brightly colored, stretchable elastomeric material that has a pair of openings spaced apart by a distance at least 2″ less than the outer reach of the arms of the cleat upon which the guard is to be used. The elastomeric material is preferably an iridescent orange that visually calls attention to the presence of the dock cleat. In addition, phosphorescent chemicals are preferably blended into the guard material enabling it to be seen at night. The visual guard of the present invention is designed to allow use of the cleat with out the need to remove it, i.e., a rope may be attached to the cleat either over or under the cleat guard without compromising the function of the guard nor the cleat. In this manner, the guard continues to function without risking loss or misplacement resulting from removal nor threatening passersby with an unguarded cleat. Since the cleat guard is elastomeric it will afford some resistance to physical contact but, since a major portion of the cleat remains exposed to permit its use, the primary protection provided by the guard of the present invention is to a visual warning.
Various other features, advantages and characteristics of the present invention will become apparent to one of ordinary skill in the art after a reading of the following specification.
BRIEF DESCRIPTION OF THE DRAWINGS
The preferred embodiment(s) of the present invention is/are described in conjunction with the associated drawings in which like features are indicated with like reference numerals and in which
FIG. 1
is a perspective view of a first embodiment of the visual guard for a dock cleat of the present invention;
FIG. 2
is a top view of the guard of the first embodiment; and
FIG. 3
is an edge view of the guard of the first embodiment.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENT(S)
The first preferred embodiment of the visual guard for a dock cleat is shown in
FIGS. 1-3
generally at
20
. Guard
20
is flat and generally rectangular with rounded ends
26
(oblong) and has a first opening
22
and a second opening
24
spaced by a distance generally about 2″ less than the distance between the outermost reaches of first (
13
) and second (
15
) arms on dock cleat
11
. A suitable material for the guard of the present invention is a hybrid of SBR rubber and PVC identified as SCM available from Rubatex Corp., 5223 Valley Park Dr., Roanoke, Va. 24019. Other suitable elastomeric materials could also be used. Such alternative materials should have a comparable durometer (50-55 Shore), resistance to ultraviolet radiation, be buoyant, non-absorbent, tough, durable, with good resistance to petroleum products. It is also preferred that the pigment, a bright orange of the type used for life jackets and the like, be incorporated directly into the elastomer so that it cannot chip, peel or flake off the guard
20
. Further, preferably phosphorescent material is incorporated with the orange pigment so that the cleat guard
20
can be seen at night.
As seen in
FIG. 1
, when deployed, guard
20
leaves cleat arms
13
,
15
and through bore
17
of cleat
11
available for securing of a hawser. The rope may be attached above or below the guard
20
without impairing the function thereof and, similarly, the presence of guard
20
on cleat
11
does not adversely impact the use of cleat
11
. Accordingly, unlike other cleat guards, guard
20
need not be removed to attach or detach a rope securing a boat to the dock and is therefore not at risk to be lost, or simply forgotten once the rope is untied and the boat casts off
The visual guard
20
of the present invention will provide some physical protection to a passerby, in the same manner a curb feeler affords some protection against a curb contacting the sidewall of a tire. However, the primary protection for persons is the brightly colored guard
20
calling visual attention to the presence of the cleat
11
so the passerby can alter her/his footfall to avoid contact therewith. The phosphorescent chemicals introduced into the guard material enables it to be seen at night. The cleat guard
20
of the present invention is simple and inexpensive and less likely to become lost, greatly increasing its effectiveness.
While the cleat guard
20
has been disclosed for use on dock cleats, it is conceivable that a smaller version could be used on the deck cleats of some larger boats to similarly visually warn those walking the decks or the presence of the cleat reducing incidents of undesired contact between their foot and the cleat. It will be understood that a variety of sizes of guards
20
will be required to accommodate the variety of different sizes of cleats.
Various changes, alternatives and modifications will become apparent to one of ordinary skill in the art following a reading of the foregoing specification. It is intended that any such changes, alternatives and modifications as fall within the scope of the appended claims be considered part of the present invention.
