Abstract
An adjustable depth truss for a flying table comprised of an upper and lower chord held in spaced relationship to each other by diagonal supports attached by connectors received within holes spaced along the length of the chords. The connectors are selectively positionable in the holes to change the angle at which the diagonals are mounted to the chords, thereby varying the distance between the chords and adjusting the depth of the truss.
Claims12
An adjustable depth truss comprising:
- first and second chords, each of said chords having a plurality of pre-existing holes therethrough spaced along the length thereof;
- a plurality of diagonal supports, each of said diagonal supports having a hole at each end thereof;
- a first set of connectors selectively positioned within a first set of the pre-existing holes in said chord;
- and
- a second set of connectors positioned within a selected set of the pre-existing holes through said second chord, said first set of connectors being received within the holes at one end of each of said diagonal supports and said second set of connectors being received within the holes at the other end of each of said diagonal supports, said first set of connectors being selectively positionable in any one of a plurality of second sets of the pre-existing holes in said first chord for changing the angle at which said diagonal supports are mounted relative to said first and second chords to provide multiple positions and angles of said diagonal supports for adjusting the space between said first and second chords without changing the length of said diagonal supports or changing the hole in said diagonal supports in which said first and second set of connectors are received.
