Abstract. A sling fishing reel comprising a gun assembly (gun body, line guide, faux trigger, trigger guard, thumb rest slot), a frame assembly (upper and lower lateral supports, handle rod, rod butt gimbal, arm support wire and arm support, reel sit tube and reel wedges), and a fishing reel attached to the reel sit tube.

Inside The Invention

Three Assemblies, One System

The patent describes the Sling Reel as three integrated assemblies — each engineered to do a job conventional rod-and-reel gear can't.

Gun Assembly

The handling and aiming core. Held and aimed like a sighted launcher, it puts casting control in the angler's hands.

  • Gun body
  • Line guide with line-guide slot
  • Faux trigger & trigger guard
  • Thumb-rest slot
  • Picatinny rail + adjustable D-ring
  • Right & left handle grips

Frame Assembly

The structural backbone. It braces against the angler's arm and body to transfer leverage during the fight, and breaks down for transport.

  • Upper & lower lateral supports
  • Handle rod
  • Rod butt gimbal
  • Arm support wire & arm support
  • Reel sit tube
  • Reel wedges, knurled jam nut & washer

Fishing Reel

The drivetrain. A fishing reel mounts to the reel sit tube, secured by the reel wedges — the part that stores line and fights the fish.

  • Mounts to the reel sit tube
  • Secured by first & second reel wedges
  • Locked with knurled jam nut & washer
What The Patent Protects

The Claims, In Plain Language

A patent's claims define exactly what is protected. Here are the six granted claims of US 12,610,931 B1, translated out of legalese.

01
Claim 1 of 6

The complete sling fishing reel: a gun assembly (gun body, line guide with slot, faux trigger, trigger guard, thumb-rest slot, Picatinny rail with adjustable D-ring, and right/left handle grips), a frame assembly, and a fishing reel attached to the reel sit tube.

Summaries are paraphrased for clarity; the granted claims in the certificate are authoritative.

Why It's Different

Innovation Backed By Intellectual Property

These are the goals the patent set out to achieve — and what makes the Sling Reel a genuinely new category of offshore gear.

  • Rod-less platform

    A rod-less fishing platform purpose-built for deep-sea offshore fishing.

  • Packs down

    Volumetrically efficient — easy to carry, transport, and store.

  • Tool-less assembly

    Readily assembled and disassembled without any special tools.

  • Built to last

    Durable, reliable construction for demanding offshore conditions.

  • Genuinely new

    A novel mechanism — the applicant is aware of no prior reel with these features.
