Abstract: A mounting structure has characteristics, properties, or features that provide stability for the accessories mounted or supported in relation thereto. The mounting structure may be in the form of a rigid or a semi-rigid composition, which may be formed at least in part by, or sufficiently covered or coated with, a material having a damping capacity, or an ability to isolate an accessory for a vessel, a slotted track supported in relation to the vessel, or a mounting arrangement supported in relation to the vessel or the slotted track. The mounting structure may be in the form of an extension arm for offsetting the accessory laterally, crosswise or transversely in relation to the vessel, slotted track, or mounting arrangement. The extension arm may include, or carry, a surface, that is configured to interlock with a surface of a mating structure, namely, a mounting arrangement and/or an accessory or accessory mount.

Abstract: A tee-bolt for use with an accessory mounting track provides a quick and easy removable attachment of various devices. The tee-bolt comprises a head comprising upper and lower surfaces and a female threaded hole passing therethrough between the upper and lower surfaces, and a stud comprising a male thread having an end threaded through the head so that the end is flush with the lower surface of the head and a portion of the stud extends from the upper surface of the head. The end of the stud is flared outwardly within the threaded hole and flush with the lower surface of the head by the application of pressure to form a flare that interacts with the head to inhibit separation of the head and the stud.

Abstract: An accessory mount allows accessories to be removably and adjustably mounted to a surface. In an example, the surface may be that of a watercraft, and the accessory may be a fishing rod. The mount may be used with a track fixable to an environmental surface or mounted directed to the environmental surface. When used with a track, a post of the accessory mount releaseably engages the track. Slidable engagement of the post allows lateral or horizontal adjustment of the accessory. An accessory engaging member is adjustable in relation to the post about a horizontal axis and a vertical axis, so that angular and azimuthal rotational adjustments of the accessory are enabled. A single lever is used to make angular and rotational adjustments, and to release the accessory engaging member from the post.

Abstract: An accessory device is provided with one or more physical interlocks for mating with a slot provided along an accessory mounting track, or alternatively, with discrete physical mating interlocking features provided along an accessory mounting track, such as along opposing sides of the slot. In this way, the accessory device can be mounted along the slot in a lengthwise direction of the accessory mounting track or perpendicularly or transversely to the lengthwise direction of the accessory mounting track. When mounting in a lengthwise direction of the accessory mounting track, the accessory device is prevented from moving along the accessory mounting track when sufficient frictional forces are applied. When mounting perpendicularly or transversely to the lengthwise direction of the accessory mounting track, the interlocks mate with the interlocking features to prevent movement of the accessory device along the accessory mounting track.

Abstract: A T-bolt locking device provides positive engagement of a T-bolt with a track as well as prevents disengagement from the track when loosening the T-bolt sufficiently to allow movement of an accessory along a slot in the track to a new position. Tightening the accessory onto the T-bolt secures flanges of the head of the T-bolt against an inner surface of the track while fixing the accessory to the track. The T-bolt locking device comprises opposing tabs configured to pass through the slot in the track and receive the flanges of the head of the T-bolt, whereby the locking device is in the engaged position, preventing rotation of the head of the T-bolt in relation to the tabs. When fastening the T-bolt and locking device, if the locking device does not seat against the track surface, this indicates that the T-bolt is under-rotated and not properly engaged with the track because the opposing tabs of the locking device are contacting the upper face of the T-bolt flange.
