Publication number: 20240116318Abstract: Apparatuses, systems, and methods for determining and verifying operational states of fifth wheels. Certain methods for determining the operational state of the fifth wheel may include sensing, with at least one sensor, magnetic flux caused by a magnet on a movable component movable to lock the fifth wheel to a kingpin of a towed vehicle and determining an end position of the movable component based on the magnetic flux. The end position of the movable component is then compared to a threshold position and an operational state of the fifth wheel is determined based on the comparison of the end position of the movable component to the threshold position.Type: ApplicationFiled: December 20, 2023Publication date: April 11, 2024Applicant: Fontaine Fifth Wheel CompanyInventors: Carl Gaufin, Michael Shane Wolfe

Publication number: 20230347694Abstract: A fifth wheel system includes a fifth wheel configured to couple to a kingpin of a towed trailer such that vibrations are generated when the fifth wheel couples to the kingpin. A sensor in operative association with the fifth wheel and configured to sense the vibrations and generates vibration data. A controller receives the vibration data and processes the vibration data to detect a presence or an absence of a predetermined vibration component that occurs when the fifth wheel properly couples to the kingpin. An indicator indicates proper coupling of the fifth wheel to the kingpin when the predetermined vibration component is present.Type: ApplicationFiled: July 10, 2023Publication date: November 2, 2023Applicant: Fontaine Fifth Wheel CompanyInventors: Carl Gaufin, Ryan Fechner

Patent number: 11124031Abstract: A fifth wheel for locking to a kingpin of a towed trailer includes an operating arm pivotable into and between a locked position for locking the kingpin in the fifth wheel and an unlocked position in which the kingpin can be removed from or inserted into the fifth wheel and a housing coupled to the operating arm. A pull handle is slidable in the housing into and between an extended position in which the pull handle extends from the housing and a retracted position in which the pull handle is retracted into the housing. A spring in the housing biases the pull handle towards the retracted position. When the operating arm is pivoted into the locked position the pull handle is forced into the extended position, and after the operating arm is pivoted to the unlocked position the pull handle moves to the retracted position.Type: GrantFiled: February 12, 2019Date of Patent: September 21, 2021Assignee: Fontaine Fifth Wheel CompanyInventors: Michael Shane Wolfe, Russell Wayne Melton

Patent number: 10351185Abstract: A fifth wheel coupling device is adapted for a towing vehicle that vertically receives a kingpin of a trailer. The device includes a plate having a kingpin hole formed therethrough defining a vertical path adapted to permit entry of the kingpin into the kingpin hole and through the plate along the vertical path, and to prevent release of the kingpin out of the kingpin hole along a lateral path leading outside the plate. A support base is attached to the plate, and is adapted to mount the plate to the towing vehicle. A lifting mechanism is operatively connected to the plate and is adapted to be mounted on the towing vehicle for raising and lowering the plate relative to the trailer. A locking mechanism is movably attached to the plate and is provided with an actuating portion.Type: GrantFiled: May 8, 2017Date of Patent: July 16, 2019Assignee: Fontaine Fifth Wheel CompanyInventors: James Matthew Rhodes, Robert Keith Laney, Steven W.

Patent number: 9738333Abstract: A fifth wheel includes a top plate having a throat that is adapted to receive a kingpin of a trailer. A pair of locking jaws are pivotally connected to the top plate and pivotal between a closed configuration where the pair of locking jaws block passage of a kingpin out of the throat and the locking jaws are held primarily in compression and an open configuration where a kingpin may pass into and out of the throat. Each of the pair of locking jaws has an engagement surface adapted to engage a kingpin positioned in the throat when the pair of locking jaws are in the closed configuration. A locking member is movably attached to the top plate and a mechanism urges the locking member into engagement with the pair of locking jaws when the pair of locking jaws are in the closed configuration.Type: GrantFiled: February 9, 2015Date of Patent: August 22, 2017Assignee: Fontaine Fifth Wheel CompanyInventors: Steven Alldredge, Timothy Johnson

Publication number: 20150158355Abstract: A fifth wheel includes a top plate having a throat that is adapted to receive a kingpin of a trailer. The fifth wheel is equipped with a locking mechanism including a jaw slidably connected to the top plate and slidable between a closed position where the jaw blocks passage of a kingpin out of the throat of the fifth wheel and an open position where a kingpin may pass into and out of the throat of the fifth wheel. The jaw has an edge adapted to engage a kingpin positioned in the throat of the fifth wheel when the jaw is in the closed position. A release arm is pivotally attached to the top plate and the jaw. A trigger member is pivotally attached to the release arm and has a locking head. A main spring urges the jaw towards the closed position. A locking protrusion is attached to the top plate and is engaged by the locking head of the trigger member when the jaw is in the open position so as to prevent the jaw from moving into the closed position.Type: ApplicationFiled: December 9, 2013Publication date: June 11, 2015Applicants: Fontaine Fifth Wheel Company, Fontaine Fifth WheelInventors: Steven Alldredge, Tim Johnson, Todd Shelton, Charles Rosato

Patent number: 7651113Abstract: In a fifth wheel hitch, a locking mechanism for retaining a trailer kingpin within a fifth wheel slot. The locking mechanism includes a jaw assembly comprised of a cam arm pivotally attached at one end to the underside of the hitch plate, a bumper arm pivotally attached by one of its ends to the cam arm, a sliding jaw with a recess for receiving the kingpin shank, and a secondary lock member, pivotally attached at a point intermediate its two ends to the rear portion of the cam arm. The locking mechanism also includes a main spring to pull the free end of the cam arm toward a closed position. A release rod is coupled at one end to secondary lock member at an attachment point that is disposed away from the lock member's axis.Type: GrantFiled: March 6, 2007Date of Patent: January 26, 2010Assignee: Fontaine Fifth Wheel CompanyInventor: Steven William Mann

Patent number: 5641174Abstract: A interconnection of the jaw, wedge and operating handle in a fifth wheel facilitates the provision of an indicator on a secondary locking mechanism which further insures the security of the system. In the invention, the jaw is connected to the operating handle by a pivoting timing lever which pivots off a pin on the jaw such that the jaw remains engaged with the fifth wheel until the wedge is substantially removed from engagement with the jaw. In cooperation with the primary locking mechanism, a secondary lock is provided at the end of the operating handle such that a pawl arrangement engages a stop on the fifth wheel assembly until positively released by the operator. The pawl arrangement further has a mechanical indicator which extends beyond the fifth wheel assembly and allows the operator to determine whether the king pin is engaged and the secondary lock is activated.Type: GrantFiled: May 15, 1995Date of Patent: June 24, 1997Assignee: Fontaine Fifth Wheel CompanyInventors: Jeff M.

Patent number: 4946183Abstract: A pull handle for a fifth wheel utilizes a sliding connection to the operating handle of the locking jaw of the fifth wheel. A retractor spring biases the pull handle inwardly along the sliding connection such that the pull handle assumes a position which will not engage the tires of the tractor with the lock mechanism open, regardless of the adjustment of the suspension of the tractor.Type: GrantFiled: December 15, 1988Date of Patent: August 7, 1990Assignee: Fontaine Fifth Wheel CompanyInventors: W.
