Publication number: 20120104220Abstract: A truck tractor trailer hose support for hoses and cables extending there between, including an adjustable vertical support member; a tubular hose support cradle member radially angled to approximately 90°, mounted on the vertical support member; and a mounting assembly which allows the vertical support member to returnably pivot at its base, under spring tension, to approximately 90° maximum from vertical, in any direction. The hose support cradle member is held pivotally in place on top of the vertical support member by extension springs mounted to each side of the hose support member and the corresponding sides of the vertical support member. The tubular support member and the vertical member are both returnable to their upright position by spring tension. The mounting assembly for the vertical support member is constructed of two parallel plate members with three or more compression/extension spring combinations.Type: ApplicationFiled: August 15, 2011Publication date: May 3, 2012Inventor: Albert Korson

Patent number: 7766299Abstract: A support post for a flexible substrate includes a primary base and a secondary base adapted to rest upon the primary base. The secondary base supports an upright substrate support member. The secondary base is selectively secured to the primary base to orient the upright substrate support at such angle as may be required to maintain the flexible substrate in a taut condition.Type: GrantFiled: November 30, 2006Date of Patent: August 3, 2010Inventors: Jack S. Titus, II, Shannon Ahern

Patent number: 6935693Abstract: A suspension for a seat that varies the preload, spring rate and damping rate of the suspension in direct proportion to the suspended weight of an occupant of the seat to provide the same effective vibration isolation for any occupant. The suspension includes an actuating mechanism engaged with a first spring and a pivotal transfer link that is engaged with a second spring and a non-adjustable rate damper that are each fixedly attached to the seat opposite the transfer link. The transfer link is engaged with a weight adjustment mechanism which operates to adjust the position of a pivot pin for the transfer link with respect to the transfer link, such that the preload, spring rate and damping rate of the suspension are adjusted in proportion to the weight of the occupant of the seat to provide similar ride dynamics to any occupant of the seat.Type: GrantFiled: March 21, 2003Date of Patent: August 30, 2005Assignee: Milsco Manufacturing, a Unit of Jason IncorporatedInventors: Ryan Derrick Janscha, Kevin Earl Hill, Dean Davis-Troller, Bradley S. Boyles, John Kucharski

Patent number: 6186467Abstract: An adjustable suspension for a vehicle seat mounted on a scissors linkage wherein the spring supporting suspension force may be adjustable over a wide range of user weight, and wherein the scissors linkage permits the seat, which may include a back, to move in a substantially vertical direction during seat suspension movement.Type: GrantFiled: May 6, 1999Date of Patent: February 13, 2001Assignee: Michigan Seat CompanyInventor: Robert J. Wahls

Patent number: 5409192Abstract: A load equalizing pier for a coach comprises a stand for placement on the ground and a head for placement under a load, e.g. a coach beam. The stand includes means for adjusting the height of the head. The head includes a base plate for attachment to the top of the stand and a support plate for placement under the load. Springs, supported by the base plate bias the support plate toward a biased position separated from the base plate. Bolts retain the support plate to the base plate above the base plate such that the support plate is movable downward from a biased position to a stop position restrained by the base plate. The springs apply a biasing force less than the desired load such that said support plate, under desired load, is restrained from further downward movement by said base plate. Preferably, the springs apply a biasing force of less than half of the desired load.Type: GrantFiled: August 12, 1993Date of Patent: April 25, 1995Inventor: James Oliver

Patent number: 5176356Abstract: A seat suspension having a stationary support that can be mounted on a vehicle. An intermediate frame is mounted on the stationary support for vertical sliding movement relative thereto by a spring suspension. A seat support frame is mounted on the intermediate frame for upward or downward movement relative thereto. A ratchet assembly interconnects the seat support frame and the intermediate frame and includes ratchet members on one of the frames and a pawl member on the other of the frames. A pawl release, including a biasing spring and a pawl actuating member, is provided to allow the support frame to be moved from the lower to any intermediate upper position and create an impulse at each position without need to activate said activating member. The activating member is operative to selectively move the pawl to a nonengagement position.Type: GrantFiled: November 27, 1991Date of Patent: January 5, 1993Assignee: Milsco Manufacturing CompanyInventors: James R. Lorbiecki, Ronald T. Uecker, Bruce B. Dahlbacka

Patent number: 4838514Abstract: A vehicle seat frame assembly comprises a stationary support frame having two laterally spaced-apart side support plates attachable to a vehicle and on which is mounted a vertically movable seat frame which comprises a horizontal seat portion and a vertical backrest portion. An upper rod is horizontally supported in slots formed in the upper ends of the side support plates. Rotatable rollers attached to opposite ends of the rod are engaged in roller guide boxes which are rigidly secured to the lateral sides of the seat frame backrest portion to guide and support the seat frame. An elongated swing arm is pivotally connected at its rear end and at its front end to the lower end of the support frame and to the front end of the seat portion, respectively, to help support the seat frame. A spring shelf and a header plate are rigidly secured to the seat frame near the lower and upper ends, respectively, of the backrest portion.Type: GrantFiled: June 3, 1988Date of Patent: June 13, 1989Assignee: Milsco Manufacturing CompanyInventor: Kevin E. Hill

Patent number: 4732357Abstract: A lightweight tilt mounting head, for such as television cameras or the like, having reactionary moment producing means to provide moments equal to the out of balance moments produced as the C of G of an article mounted on the head is rotated about the vertical.Type: GrantFiled: April 14, 1986Date of Patent: March 22, 1988Assignee: W. Vinten LimitedInventor: Richard A. Lindsay

Patent number: 4448386Abstract: Low profile resilient suspension utilizes a pair of horizontally positioned, adjustably tensioned springs to support the weight of a seat occupant. The springs are mounted to one of the movable or fixed seat frame members so as to be completely independent of the linkages, such as scissors links, which guide the movable seat frame member for generally vertical parallel movement relative to the base frame member and floor. The tension of the springs can be adjusted by weight adjustment control members fixed to one of their ends to accommodate occupants of differing weights. The adjustment can be made when the seat is either occupied or unoccupied. The weight adjustment control members remain fixed relative to the seat frame as the suspension oscillates vertically. The opposite ends of the springs are mounted to the ends of the short arms on a pair of connected bellcrank levers which are pivoted to one of the seat frame members.Type: GrantFiled: December 1, 1981Date of Patent: May 15, 1984Assignee: UOP Inc.Inventors: David Moorhouse, David E.
