Abstract
A collapsible cleat assembly positionable selectively into a stored position defined by a cleat member disposed into the interior of a cavity integrally formed in a mounting base wherein the cleat member is substantially flush with an outer exposed surface of the mounting base so as not to provide any significant protrusion above the surface of the deck or dock in which the cleat assembly is mounted. The cleat member is selectively pivotal substantially 90 degrees out of the cavity into an operative, upstanding position above the deck or dock surface for attachment and retention of a mooring line or the like and further wherein the mounting base including the cavity is set into a formed recess within the deck surface or dock surface on which the cleat assembly is mounted so as to transfer, at least in part, stresses or focuses to the entire mounting base rather than the connecting structure for securing the cleat movably to the mounting base.

Description
Background of the Invention
1. Field of the Invention
A cleat assembly capable of being mounted in a recessed configuration on the deck of a marine craft or alternately on a dock to which the craft is secured as by a mooring line or the like wherein a cleat member is selectively positionable between a stored position, flush with the supporting surface and within a cavity of the mounting base of the cleat assembly or alternately in an upright outwardly extending operative position for attachment to the mooring line.
2. Description of the Prior Art
The use of cleats to secure a line either on the deck of a marine craft or alternately on the surface of a dock is well known for the attachment of mooring lines or other lines associated with the operation of the marine craft. Typically, such cleat structures are of a conventional configuration which may vary in size dependent upon their intended use or size of the craft on which they are used. Also, it is conventional in the prior art to fixedly secure these cleat members in an upwardly and outwardly extending position on the surface of the deck of the marine craft or the dock so as to readily present such cleat members in a convenient location for line securement.
One problem associated with the conventional mounting of cleat structures is their outward fixed protrusion providing a continuous safety hazard when not in use. It is common for passengers or crew to trip or stumble over such protruding cleat structures causing injury to themselves as well as the danger of falling overboard during operation of the craft. In order to avoid the problems associated with the fixed location of cleats but recognizing their necessity in the proper operation and/or mooring of a marine craft, the prior art has made attempts to provide cleat structures which are capable of being positioned in a stored, out of the way position or selectively disposed in an operable position. Prior art structures of the type set forth herein are generally represented in the U.S. Pat. Nos. 1,402,496; 4,270,478; and 4,354,445. However, in each of the structures disclosed in the above-referenced patents, the exertion of stress or force on the cleat results in undesirable or relatively excessive forces being exerted on perhaps the weakest portion of the structure.
Accordingly, there is a need in the marine industry for a cleat structure capable of being selectively positioned between an operative and a stored position and which is otherwise structured and configured to transfer forces exerted thereon such as when a mooring line is attached thereto which effectively distributes the "pulling" force throughout a mounting base as well as the cleat structure and its interconnection to the mounting base.
Summary of the Invention
The present invention relates to a cleat assembly of the type movably positionable and secured to a mounting base so as to be selectively disposed between a stored position and an upstanding operative position. The mounting base includes an outwardly extending flange integrally formed thereon and comprising an outer exposed surface. A cavity is formed in the base in essentially surrounded relation by the outer exposed surface and depending downwardly from the undersurface of the flange. The cavity is dimensioned and configured to receive the cleat member such that it is disposed in a somewhat parallel orientation to the exposed surface of the mounting flange and disposed therebeneath within the interior of the cavity. The relative positions and dimensions of the cleat member and the cavity are such that when in the stored position, as defined above, the cleat member is substantially flush with the exposed surface so as not to present any type of obstruction or hazard to one walking along the surface in which the subject cleat assembly is mounted.
An operative position of the cleat member is defined by it being effectively pivoted or rotated substantially 90 degrees out of its stored position within the cavity so that it extends transversely upright out of the cavity and in substantially perpendicular relation to the outer exposed surface of the flange of the mounting base. In such operative position, the cleat element is disposed for engagement and support of a mooring line or like line required on the marine craft for its operation, such as on a sailing vessel. The cleat preferably comprises two support legs spaced apart from one another wherein their distal end is secured to and pivotal about a mounting pin attached to the mounting base adjacent the cavity and generally below the flange of the mounting base.
A space is specifically provided between the mounting legs for placement of one or more fingers such that the cleat member can easily be removed out of the cavity from its stored position to its operative position. Further, a friction washer having a spring effect serves to interconnect each of the legs to an inner surface of the cavity and in movable relation to the pin to the pin thereby serving to maintain or provide a tendency of the cleat member to maintain its disposition in whatever position it is located. Therefore, the cleat member will not have a tendency to inadvertently fall into the stored position when it is desired to maintain it in its upright operative position.
Another feature of the present invention comprises the securement of the mounting base to the deck surface or dock surface by means of a recess formed in the deck surface or dock surface. The cavity or outer walls of the cavity fit within the recess and the flange is disposed in substantially flush, coplanar relation to the outer exposed surface of the dock surface or deck surface. By virtue of the conformance in configuration of the recess in which the mounting base is formed to the exterior configuration of the cavity, forces will be distributed throughout the mounting base as well as on the cleat structure itself when the cleat structure is secured to a line moored to a dock or any other line used on the craft itself. Securement of the mounting base in the aforementioned manner is accomplished by a plurality of apertures being formed on the base and bolts or like connectors extending through the apertures into an anchored relation in the deck surface or dock surface on which the cleat assembly is mounted. The structure and configuration of the subject cleat assembly serves to distribute the stress load away from the deck and mounting bolts into the solid material mounting base. The relationship and securement of the cleat member to the mounting base will reduce or alleviate some of the force being applied directly to the mounting pin thereby exerting a shearing force thereon. The pulling force to which the cleat is subjected is extended in a fore and aft motion, generally not more than 40 degrees to a parallel pull on the total unit. Any stress present due to this motion is transferred from the base of the cleat against the vertical side of the mounting base rather than the pivot pin.
The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the invention will be indicated in the claims.

Detailed Description of the Preferred Embodiment
As shown in FIGS. 1 through 8, the present invention is directed to a cleat assembly generally indicated as 10 of the type intended to be mounted on the deck 12 of a marine craft or the like and have a line 13 attached thereto. Alternately, the cleat assembly 10 can be mounted in a dock surface 14 formed of a variety of materials including cementitious material 16 (see FIG. 8).
The cleat assembly 10 comprises a mounting base 18 including an integrally formed peripheral flange 20 and a cavity 22 integrally secured to the flange 20 and depending downwardly therefrom such that it extends below the flange as well as an outer exposed surface 20' of the flange. With regard to FIGS. 3, 4 and 6, it is clearly seen that the cavity 22 includes an exterior wall 24 disposed in surrounding relation thereto and defining the boundaries of the cavity 22 at least to a certain extent. An important feature of the present invention is the mounting of the cleat assembly 10 in a manner which requires the formation of a recess 26 within the surface of the deck 12 or dock 14. This is formed generally into the configuration of the exterior wall 24 surrounding the cavity 22 and may be formed as by routing or any other applicable conventional manner. Therefore, the exterior surface of the wall 24 firmly engages the interior surface of the recess 26 providing meaningful and adequate support to the mounting base 18.
The cleat assembly 10 further comprises a cleat member 30 having a conventional upper arm structure 32 and two depending mounting legs 34 spaced from one another by space 36. The distal ends of each legs 34 are pivotally secured to a mounting pin 38 secured adjacent to the cavity 22 and disposed below the mounting flange 20. A spring or friction washer 35 is disposed in functional engagement between the support legs 34 and the inner surface of the cavity or mounting base 18 and around support pin 38 so as to provide sufficient friction between surfaces engaged by washer 35 as shown in FIGS. 2A and 2B and thereby produce a tendency of the cleat member 30 to maintain its upright or alternately its stored position as respectively shown in FIGS. 3 and 2.
As is further shown in FIGS. 4, 6 and 8, the stored position of the cleat member 30 is such as to be substantially flush with the exposed surface 20' of flange 20 thereby eliminating any obstacle over which one could trip when for example the cleat member 30 is in its upright or operative position as represented in FIGS. 1, 3 and 5. Therefore, the depth of the cavity 22 is such as to receive substantially all of the cleat member 30 therein so as to define the stored position such that the cleat member 30 is substantially parallel to the flange 20 and having a majority of the cleat member located below the flange 20 within the cavity. As a practical matter, a minimal amount of the cleat member 30 may in fact protrude above the surface 20' as best shown in FIG. 4. However, the position of FIG. 4 is still considered to be "flush" within the context of the present invention in that it clearly does not present any type of obstacle over which one would trip when walking on the deck or dock surface on which the cleat assembly 10 is mounted. Also as shown in the preferred embodiment herein, the peripheral configuration of the cavity 22 substantially corresponds to the configuration of the cleat member 30.
Actual securement of the cleat assembly 10 to the deck 12 or dock 14 (FIGS. 7 and 8) is accomplished by connecting means comprising a plurality of apertures 42 integrally formed in and extending through the flange 20. Further, a plurality of connectors as at 44 extend through the apertures 42 and are embedded in the material defining the deck 12 or the dock 14 (see FIGS. 7 and 8).
Now that the invention has been described,
