Apparatus and system for securing an accessory to an object

Abstract

A restraining device, such as a bolt, pin, or latch, removably secures a connector sleeve to a U-bolt, such as a tow-rope-eyelet on the bow of a boat hull. The connector sleeve is machined with an internal cavity having surfaces and dimension that correspond to outer surfaces of the U-bolt. The sleeve contains holes through which the restraining device passes after the sleeve has been slid over the U-bolt such that the restraining device, while installed, prevents the sleeve from sliding back off of the U-bolt. The sleeve also includes accessory mount holes to receive restraining devices that attach an accessory, such as a ladder, to the sleeve and thus to the boat via the sleeve that has been secured thereto. The sleeve may provide for set screws to snug the sleeve to the U-bolt if clearance exists between surfaces of the cavity and the U-bolt.

(18) As a preliminary matter, it will be readily understood by those persons skilled in the art that the present invention is susceptible of broad utility and application. Many methods, embodiments, and adaptations of the present invention other than those herein described as well as many variations, modifications and equivalent arrangements, will be apparent from or reasonably suggested by the substance or scope of the present invention.

(19) Accordingly, while the present invention has been described herein in detail in relation to preferred embodiments, it is to be understood that this disclosure is only illustrative and exemplary of the present invention and is made merely for the purposes of providing a full and enabling disclosure of the invention. The following disclosure is not intended nor is to be construed to limit the present invention or otherwise exclude any such other embodiments, adaptations, variations, modifications and equivalent arrangements, the present invention being limited only by the claims appended hereto and the equivalents thereof.

(20) The terminology used herein is for purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well as the singular forms, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof.

(21) Unless otherwise defined, all terms (including technical, scientific, and nautical terms) used herein have the same meaning as commonly understood by one having ordinary skill in the art to which the aspects described herein belong. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

(22) It will be understood that a number of techniques and steps are disclosed. Each of these has individual benefit and each can also be used in conjunction with one or more, or in some cases all, of the other disclosed techniques. Accordingly, for the sake of clarity, this description refrains from repeating every possible combination of the individual steps in an unnecessary fashion. Nevertheless, the specification and claims should be read with the understanding that such combinations are entirely within the scope of the invention and the claims.

(23) New devices, assemblies, apparatuses, and methods for temporarily, removably, rigidly attaching ladders, steps, shade structures, and/or other apparatuses are described herein.

(24) Turning now to the figure, FIG. 1A depicts a close-up view of a ladder mount 2, adjustable ladder mount holder 10, and U-bolt connector sleeve 8 about to be removably rigidly secured, or attached, to a U-bolt 6 mounted in the bow of a boat 4. U-bolt connector sleeve 8 may define surfaces of cavity 12 in a proximal end of the sleeve (i.e., close to boat 4) each with an interference fit, or press fit, or with a clearance fit with preferably no more than 0.10″ clearance between each of the outer radius, inner radius, top of the parallel arm, bottom of the parallel arm, and sides of the parallel arms of a U-bolt 6. It will be appreciated that instead of a clearance between inner surfaces of cavity 12 and U-bolt 6, the cavity 12 may be formed such that one or more of the inner surfaces thereof may produce an interference, or press fit, with one or more of the corresponding outer radius, inner radius, top of the parallel arm, bottom of the parallel arm, and sides of the parallel arms of a U-bolt 6 when sleeve 8 has been slid, or moved into a position to be secured, over U-bolt 6. Having contact surfaces within cavity 12 of U-bolt connector sleeve 8 in very minimal clearance fit, or a slight interference fit, when sleeve 8 is fit over U-bolt 6 significantly eliminates movement of the U-bolt connector sleeve in relation to the U-bolt. For example, contact edges/outer surfaces 16A and 16B of U-bolt 6 may have a slight interference fit, or very slight clearance fit, against/with top and bottom inner surfaces 17A and 17B of cavity 12. (See FIG. 2 for more detailed view of surfaces 16A and 16B, and 17A and 17B.) It will be appreciated that inner surfaces 17A and 17B of cavity 12 may be machined as flat surfaces such that the inner surfaces contact outer surfaces 16A and 16B, respectively, at contact edges of the outer surfaces. Or, inner surfaces 17A and 17B of cavity 12 may be machined as curved surfaces such that the inner surfaces contact outer surfaces 16A and 16B, respectively, at contact patches that comprise more surface area than an edge. A pin or bolt, or other restraining device, may be inserted through passage 18 defined in sleeve 8 to apply/create a slight clearance fit with the U-bolt's inner radius, surface 20. Surface 24 of U-bolt 6 may have a slight interference fit, or very slight clearance fit, against/with surface 26 (see, FIG. 2) of cavity 12 and thus, in cooperation with contact between surfaces 16A and B and 17 A and B, and contact between a pin or bolt, or other restraining device inserted through passage 18 and surface 20, substantially removably rigidly couples and secures sleeve 8 to U-bolt 6. The pin, bolt, or other restraining device can be easily withdrawn from passage 18 in sleeve 8 to remove contact between the restraining device and the U-bolt's inner radius surface 20 and thus facilitate removal of sleeve 8 from being mounted to boat hull 4 via U-bolt 6. It will be appreciated, as shown more clearly in other figures herein, that because passage 18 locates a restraining device that passes though cavity 12 of sleeve 8 the passage typically comprises a first passage defined in one wall of the cavity, for example the wall as seen in the view of FIG. 1A, and a corresponding second passage in a corresponding back wall of sleeve 8 that defines cavity 12, which would be a back side wall as viewed in FIG. 1A. It will be appreciated that passage(s) 18 may be referred to herein as opening(s), hole(s), or other similar nomenclature (passages 22 may be referred to with similar language) for methods or means for locating a restraining device, such as a bolt or a pin, in substantially secure/restraining contact with an inner surface 20 of U-bolt 6 when sleeve 8 is mounted to the U-bolt such that the sleeve, and an accessory mounted to it at a distal end, is removably securely attached to boat hull 4. Adjustable ladder mount assembly 10 may incorporate male and female teeth or indexing flanges to allow the ladder mount to be quickly and securely positioned and repositioned while sleeve 8 is coupled to U-bolt 6 using a restraining device though passage 18. The ladder mount may incorporate an offset portion, including bends in the main ladder tube, to mount the ladder at an elevation and distance from U-bolt 6 so that the ladder clears bow 4 and sides of the boat and is roughly perpendicular to the gunnel of the boat.

(25) FIG. 2 depicts a close-up view of a U-bolt connector sleeve and a U-bolt mounted in the bow of a boat. FIG. 2 labels the contact surfaces between the U-bolt connector sleeve 8 and U-bolt 6 which removably rigidly restrain movement of the two devices in relationship to each other. The clearance between these contact points or surfaces will preferably be no greater than 0.10″, or may produce an interference or press fit between any of the paired contact points or surfaces. Surface 26 and passage 18 in U-bolt connector sleeve 6 cooperate with U-bolt outer radius surface 24 and U-bolt inner radius surface 20, respectively, to substantially restrain relational movement in the Z direction. Surfaces 17A and 17B of U-bolt connector sleeve 8 cooperate with surfaces 16A and 16B on parallel ‘arms’ of U-bolt 6 to substantially restrain relational movement in the X direction. A restraining device through opening 18 in U-bolt connector sleeve 8 can be quickly and repeatedly applied/inserted or removed to removably fix the U-bolt connector sleeve to U-bolt 6 or to remove the U-bolt connector sleeve from the U-bolt. Opening(s)/passage(s) 18 of U-bolt connector sleeve 8 locates a restraining device, such as a push pin, bolt, spring loaded pin, slam latch, rotary latch, lock, or other mechanism that can be quickly and repeatedly applied and/or removed, to bear against inner surface 20. Holes 22 are shown defined by a solid portion of sleeve 8 (i.e., cavity 12 does not extend into the solid portion) for attaching an accessory mount assembly, for example a ladder mount assembly.

(26) FIG. 3 illustrates a close-up view of a U-bolt connector sleeve incorporating a spring-loaded pin located by opening 18 before the sleeve is attached to a U-bolt mounted in the bow of a boat.

(27) FIG. 4 shows a close-up view of a U-bolt connector sleeve incorporating a spring-loaded pin located by opening 18 attached to a U-bolt mounted in the bow of a boat.

(28) FIG. 5 illustrates a close-up view of a U-bolt connector sleeve incorporating a rotary latch located by opening 18 before the sleeve is attached to a U-bolt mounted in the bow of a boat.

(29) FIG. 6 depicts 3 illustrates a close-up view of a U-bolt connector sleeve incorporating a rotary latch located by opening 18 attached to a U-bolt mounted in the bow of a boat.

(30) The embodiment depicted in FIG. 7 shows an assembly of a U-bolt connector sleeve and an adjustable ladder mount assembly. The adjustable ladder mount assembly incorporates indexing teeth to allow the ladder mount to be easily rotated into position and secured. The ladder mount may incorporate an offset portion to mount the ladder at an elevation and distance from U-bolt 6 so that the ladder clears bow 4 and sides of the boat and is roughly perpendicular to the gunnel of the boat. The end of the ladder mount incorporates features for the quick, easy, and secure mounting of readily available nautical ladders.

(31) FIG. 8 illustrates a close-up view of an assembly of a U-bolt connector sleeve and an adjustable ladder mount assembly before attachment to a U-bolt mounted in the bow of a boat.

(32) FIG. 9 depicts the ladder mount being rotated into a new position.

(33) FIG. 10 illustrates an assembly of a bow brace/support 32, U-bolt connector sleeve 8 and an adjustable ladder mount assembly 10 attached to a U-bolt 6 mounted in/to the bow of a boat 4. The U-bolt connector sleeve depicted includes contact point 26 as represented in FIG. 2. Support 32 may attach to sleeve 8 via bolts through holes 22, which bolts may also secure mount assembly 10 to the sleeve. When a restraining device is removably installed into holes 18 and bears against surface 20, sleeve 8 is removably secured to U-bolt 6 with support 32 providing additional support for a load transferred from ladder 2 to U-bolt 6 via sleeve 8

(34) FIG. 11 shows an assembly of a bow brace, U-bolt connector sleeve and an adjustable ladder mount assembly attached to a U-bolt mounted in the bow of a boat.

(35) FIG. 12 depicts a U-bolt connector sleeve before being attached to a U-bolt mounted in the transom of a boat.

(36) FIG. 13 illustrates a U-bolt connector sleeve attached to a U-bolt mounted in the transom of a boat and a ladder attached to the U-bolt connector sleeve. Different embodiments would allow for the mounting of a ladder at different angles to the U-bolt connector sleeve and on different faces or sides of a U-bolt connector sleeve.

(37) Turning now to FIG. 14, an embodiment is illustrated that shows set screws 28A and 28B penetrating into cavity 12 such that screws 28A and 28B bear against surfaces 16A and 16B, respectively. If the upper and lower surfaces of cavity 12 create an interference fit with surfaces 16A and 16B, respectively, set screws 28A and 28B may not be needed, or may not need to be tightened. But, if a slight clearance between upper and lower surfaces 17A and 17B and surfaces 16a and 16B exists, tightening set screws 28A and 28B may provide a more secure removable attachment of sleeve 8 to U-bolt 6. Similarly, set screw 30 may be tightened against surface 24 when a restraining device installed through hole(s) 18 exists with a clearance fit with surface 20.

(38) Turning now to FIG. 15, the figure illustrates dimension 14 between upper surface 17A and lower surface 17B of cavity 12 being substantially the same as the dimension between surfaces 16A and 16B of U-bolt 6. Similarly, dimension 15 between the side surfaces o cavity 12 is shown being substantially similar to dimension 13, which is the thickness of U-bolt 6.
