Abstract

Abstract A crossbar for restraining lading in a transport vehicle. A slide is pivotally connected to one end of the bar. The slide is movable along a guide rail which extends horizontally along one side wall of the cargo space. Means are provided which prevent removal of the slide from the guide rail. A second rail extends along the opposite wall of the cargo space. In active position the bar extends across the cargo space between the two rails. A latch bolt is mounted in each end of the bar and in active position each bolt is received in a selected one of a series of apertures formed in the corresponding rail. The bar may be swung to a storage position in which it lies along the side wall of the cargo space.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 237 words
For use in the cargo space of a vehicle the combination of: a. a channel-shaped guide having its web portion adapted for connection to and extension along a wall of said space. b. a slide movable along said guide and captive therein; c. a rail parallel with said guide and adapted to extend along an opposed wall of the space d. a pivot on said slide within the guide and having its axis transverse to the direction of slide movement and parallel with said web portion; e. a bar connected by said pivot to said slide so as to swing between a storage position in which it lies along said guide and an active position in which it extends between and is supported by the guide and the rail; f. a longitudinal series of bolt receiving apertures formed in the web portion of the guide and extending longitudinally therealong g. a series of bolt receiving apertures formed in the rail and extending longitudinally therealong; h. bolt members at each end of the bar, extending longitudinally therealong, one bolt yieldingly biased so as to enter an aligned aperture in the guide and the other bolt yieldingly biased so as to enter an aligned aperture in said rail when said bar is in active position; and i. actuator means whereby one of said bolts may be withdrawn against said bias from an aperture in which it has been received.
Claim 2
Dependent Claim 237 words
For use in the cargo space of a vehicle the combination of: a. a channel-shaped guide having its web portion adapted for connection to and extension along a wall of said space. b. a slide movable along said guide and captive therein; c. a rail parallel with said guide and adapted to extend along an opposed wall of the space d. a pivot on said slide within the guide and having its axis transverse to the direction of slide movement and parallel with said web portion; e. a bar connected by said pivot to said slide so as to swing between a storage position in which it lies along said guide and an active position in which it extends between and is supported by the guide and the rail; f. a longitudinal series of bolt receiving apertures formed in the web portion of the guide and extending longitudinally therealong g. a series of bolt receiving apertures formed in the rail and extending longitudinally therealong; h. bolt members at each end of the bar, extending longitudinally therealong, one bolt yieldingly biased so as to enter an aligned aperture in the guide and the other bolt yieldingly biased so as to enter an aligned aperture in said rail when said bar is in active position; and i. actuator means whereby one of said bolts may be withdrawn against said bias from an aperture in which it has been received.
Claim 3
Dependent Claim 61 words
The combination defined in claim 1 in which: a. each bolt includes a curved surface serving as a cam to withdraw the bolt from an aperture in which it is received when the bar is in its active position and propelled along said rail and guide in a direction to cause engagement between said surface and the side of that aperture.
Claim 4
Dependent Claim 16 words
The combination defined in claim 1; and a. means to latch said bar in storage position.
