US3570412A — Captive brace rod and track

Claim 1

Independent Claim 219 words

A load brace rod comprising axially telescopic members, spring means interconnecting said members for biasing them into extended position, means limiting the extension of the telescopic members and releasably retaining them in retracted position, and support means at one end of said load brace rod, said support means including an axial stem rigid with the brace rod, and a retaining disc captively retained on said stem but capable of longitudinal movement thereon, said stem being headed for retaining the disc thereon, the opposite end of said brace rod including an axial projection for locking engagement with an opposed apertured surface, said load brace rod being suspended, when in retracted position, an overhead track system employed in a load body of a load-carrying vehicle and including a channelshaped track having downwardly extending and inturned flanges forming an overhead slotted track, said retaining disc being slidably disposed in said track with the stem received in the slot therein, said track including a plurality of apertures therein receiving the headed end of the stem for locking the brace rod in position on the track when the brace rod is extended with the opposite end engaging an opposing surface thereby spring biasing the headed end of the stem into engagement with an aperture in the track for locking the brace rod in position.

Claim 2

Dependent Claim 219 words

A load brace rod comprising axially telescopic members, spring means interconnecting said members for biasing them into extended position, means limiting the extension of the telescopic members and releasably retaining them in retracted position, and support means at one end of said load brace rod, said support means including an axial stem rigid with the brace rod, and a retaining disc captively retained on said stem but capable of longitudinal movement thereon, said stem being headed for retaining the disc thereon, the opposite end of said brace rod including an axial projection for locking engagement with an opposed apertured surface, said load brace rod being suspended, when in retracted position, an overhead track system employed in a load body of a load-carrying vehicle and including a channelshaped track having downwardly extending and inturned flanges forming an overhead slotted track, said retaining disc being slidably disposed in said track with the stem received in the slot therein, said track including a plurality of apertures therein receiving the headed end of the stem for locking the brace rod in position on the track when the brace rod is extended with the opposite end engaging an opposing surface thereby spring biasing the headed end of the stem into engagement with an aperture in the track for locking the brace rod in position.

Claim 3

Dependent Claim 55 words

The structure as defined in claim 1 wherein said headed end of the stem and apertures in the track are polygonal in configuration to prevent relative rotation therebetween, said means retaining the telescopic brace rod in retracted position being actuated and released by relative rotation between the telescopic members thereby facilitating operation of said means.

Claim 4

Dependent Claim 162 words

A load bracing assembly for a load body of a load carrying vehicle in which the load body has opposing walls, said assembly comprising an elongated track adapted to be mounted on one of the opposing walls, said track including spaced and aligned longitudinal flanges disposed in opposed relation to define an elongated slot and a plurality of longitudinally spaced socket means disposed in alignment with the slot and disposed inwardly thereof, and a brace rod including a longitudinally adjustable member extendable and retractable between the opposing walls, means on one end of said brace rod longitudinally movably attaching the brace rod to the track, and means on the same end of the brace rod to engage with the socket means in the track to lock the brace rod in longitudinally adjusted position, said means engaging the socket means in response to longitudinal extension of the brace rod and disengaging the socket means in response to longitudinal retraction of the brace rod.

Claim 5

Dependent Claim 162 words

A load bracing assembly for a load body of a load carrying vehicle in which the load body has opposing walls, said assembly comprising an elongated track adapted to be mounted on one of the opposing walls, said track including spaced and aligned longitudinal flanges disposed in opposed relation to define an elongated slot and a plurality of longitudinally spaced socket means disposed in alignment with the slot and disposed inwardly thereof, and a brace rod including a longitudinally adjustable member extendable and retractable between the opposing walls, means on one end of said brace rod longitudinally movably attaching the brace rod to the track, and means on the same end of the brace rod to engage with the socket means in the track to lock the brace rod in longitudinally adjusted position, said means engaging the socket means in response to longitudinal extension of the brace rod and disengaging the socket means in response to longitudinal retraction of the brace rod.

Claim 6

Dependent Claim 115 words

The structure as defined in claim 3 wherein said means on one end of said brace rod includes an axial stem rigid therewith, said stem being movably received in said slot, a retaining disc mounted on said stem for longitudinal movement and being slidably disposed in said track against the inner surface of said flanges, said means engaging the socket means including a headed inner end on the stem retaining the disc thereon and engaging the socket means in the track when the rod is extended with the other end engaging an opposing wall thereby urging the headed end into the socket means and locking the brace rod in longitudinally adjusted position on the track.

Claim 7

Dependent Claim 74 words

The structure as defined in claim 4 wherein said headed end of the stem and the socket means are polygonal in configuration to prevent rotation of said brace rod, said brace rod includiNg means releasably retaining the telescopic members in retracted position, said telescopic members being relatively rotatable, said releasable means being operative in response to relative rotation between the telescopic members whereby the stem and socket means facilitate operation of said releasable means.

Claim 8

Dependent Claim 63 words

The structure as defined in claim 5 wherein said telescopic members are spring biased toward an extended position, the wall of the load body opposed to the track having a plurality of socket means receiving the end of the brace rod remote from the stem when the brace rod is extended thereby positively locking both ends of the brace rod in adjusted position.
