Filed:

Appl. No.:

9/480966

Inventors:

Daniel R. Victor - Kalamazoo MI
Stanley W. McKay - Richland MI
Melvin J. Guiles - Casnovia MI
Kenneth A. Ahrens - Schoolcraft MI

Assignee:

Interkal, Inc. - Kalamazoo MI

International Classification:

E04H 312

US Classification:

52 9

Abstract:

A telescopic seating system with aisle rails in the form of discrete and lightweight uprights. A telescopic seating system, such as a bleacher system or a platform seating system, is equipped with a series of uprights, which are easily movable to positions whereby the seating system can be retracted. The railing system includes discrete lightweight and movable uprights, each having a single closed-loop upper section. The noses of the decks upon which rows of seating are mounted have sockets which receive the lower end of each upright and support the uprights in the aisles of the seating system. Because the uprights are lightweight, discrete and easily moveable, the tendency to use the seating system without installing the handrails is reduced or eliminated.

US Classification:

256 59

Abstract:

A railing system for a telescopic seating arrangement, such as bleacher systems and platform seating systems. The railing system includes discrete lightweight and readily stowable uprights, each having a single closed-loop upper section. Brackets carried by the nose of decks receive a plate affixed to the lower end of each upright. The brackets which support the uprights have a low profile so that the seating system is readily useable if the uprights are not installed. The lightweight and easily stowed uprights of this railing system eliminate the factors which lead to use of a seating system without handrails.

International Classification:

E04H 312

US Classification:

52 9

Abstract:

A deployable seating arrangement employs a plurality of seating level members that are arranged in sequentially elevated relation to one another. When the deployable seating arrangement is in an undeployed state, the seating level members are disposed substantially directly beneath one another in stacked relation. When in a deployed condition, each seating level member is disposed beneath and forward of an immediately superior seating level member in stepped relation. Each of the seating level members has associated therewith a plurality of L-shaped frame elements that are formed of vertical and horizontal portions. A roller is installed at the upper end of the vertical portion for engaging with the underside of the horizontal portion of an immediately superior seating level member. A drive arrangement having a wide track motor drive urges the seating level members, which are installed on a plurality of respective wheeled frame arrangements, into deployed and undeployed states. Each wheeled frame arrangement is arranged laterally inward of a wheeled frame arrangement associated with an immediately superior seating level member.
