Swivel Mounts For Attaching And Maneuvering Accessories Over The Gunnel Of A Boat Or Any Other Mounting Surface

Patent No. US12258111 (titled "Swivel Mounts For Attaching And Maneuvering Accessories Over The Gunnel Of A Boat Or Any Other Mounting Surface") was filed by Sea Swivel Inc on Sep 26, 2024.

What is this patent about?

’111 is related to the field of swivel mounts, specifically those used for attaching and maneuvering boating accessories like trolling motors. The background acknowledges the challenges of mounting and storing trolling motors on boats, especially larger ones, where accessibility and wave forces can be problematic. Existing solutions often require precarious access or are not robust enough for offshore conditions, creating a need for improved mounting solutions.

The underlying idea behind ’111 is to create a swivel mount that allows a user to easily position a trolling motor or other accessory over the side of a boat and then stow it inboard. This is achieved by using a rotating joint offset from the center of the mounting plate, allowing the accessory to swing in an arc. The mount is designed to be strong enough to withstand the forces exerted by waves, particularly in offshore environments.

The claims of ’111 focus on a swivel mount comprising an elongated mounting plate , a support plate shorter than half the length of the mounting plate, and a swivel element . The plates are parallel and partially overlapping, with the swivel element allowing rotation around an axis perpendicular to the mounting plate's face, offset from its centerline. Another claim focuses on a boat with such a swivel mount attached to its gunnel, with a trolling motor bracket connected to the mount.

In practice, the swivel mount is attached to the boat's gunnel, and the trolling motor bracket is bolted to the elongated mounting plate. The swivel element, which can be a bolt with bearings or an annular bearing, allows the user to rotate the trolling motor into and out of the water. A locking pin can secure the motor in a desired position. The offset pivot point allows the trolling motor to clear the side of the boat when deployed.

This design differentiates itself from prior approaches by providing a robust and easily accessible mounting solution for trolling motors, especially on larger boats. The cantilevered design of the elongated mounting plate, combined with the swivel mechanism, allows for convenient deployment and stowing of the motor. The multiple hole patterns on the mounting plate further enhance versatility by accommodating various trolling motor models and mounting brackets, simplifying installation and reducing the need for custom solutions.

How does this patent fit in bigger picture?

Technical landscape at the time

In the early 2020s when ’111 was filed, boat accessories like trolling motors were typically mounted using brackets and clamps. At a time when standardized mounting systems were not widely adopted, securing these accessories often required custom solutions. Hardware constraints made it non-trivial to design mounts that could withstand the forces exerted by waves, especially for larger boats and trolling motors with longer shafts.

Novelty and Inventive Step

The examiner approved the application because the prior art neither describes nor suggests a boat with a gunnel, a swivel mount positioned above the gunnel's upward-facing surface allowing swiveling around a perpendicular axis, a support member fastened to the gunnel using bolts or screws, and a trolling motor mounting bracket attached to the swivel mount's upward-facing surface.

Claims

This patent contains 18 claims, with independent claims 1 and 8. Independent claim 1 is directed to a swivel mount comprising an elongated mounting plate, a support plate, and a swivel element. Independent claim 8 is directed to a boat comprising a gunnel and a swivel mount with a trolling motor mounting bracket. The dependent claims generally elaborate on the features and configurations of the swivel mount and the boat.

Key Claim Terms New

Definitions of key terms used in the patent claims.

Term (Source)Support for SpecificationInterpretation
Elongated mounting plate
(Claim 1)
“An embodiment of a swivel mount includes an elongated mounting plate and a support plate each having first and second opposing faces spaced apart by one or more peripheral sidewalls, but where the support plate has a length less than or equal to half a length of the elongated mounting plate.”A plate with two opposing faces and sidewalls, where the length is a significant dimension of the plate.
Mounting member
(Claim 8)
“An embodiment of a boat includes a gunnel and a swivel mount disposed above an upward facing surface of the gunnel such that a mounting member of the swivel mount is able to swivel about an axis that is perpendicular to and passes through the upward facing surface of the gunnel.”A component of the swivel mount that allows swiveling about an axis.
Support plate
(Claim 1)
“An embodiment of a swivel mount includes an elongated mounting plate and a support plate each having first and second opposing faces spaced apart by one or more peripheral sidewalls, but where the support plate has a length less than or equal to half a length of the elongated mounting plate.”A plate with two opposing faces and sidewalls, having a length no more than half the length of the elongated mounting plate.
Swivel element
(Claim 1)
“The swivel mount also includes a swivel element. The swivel mount is configured for the elongated mounting plate, the support plate, and swivel element to be coupled together such that the first faces of the support plate and the elongated mounting plate are parallel and the swivel element, the support plate, and the elongated mounting plate at least partially overlap each other.”A component that allows the elongated mounting plate to rotate about an axis.
Trolling motor mounting bracket
(Claim 8)
“The boat further includes a trolling motor mounting bracket coupled to an upward facing surface of the mounting member.”A bracket specifically designed to attach a trolling motor to the swivel mount.
