Abstract
A security device, such as an anti-theft device, for a transport vehicle, such as a railcar, grating hinge connector includes a plate and a cup. The hinge connector has a first portion secured to the deck surface by a fastener with a head, and a second portion coupled to the grating. The cup has a base and a wall forming a cavity sized and shaped to receive the plate. The wall forms an opening that is sized and shaped to receive the plate for insertion into the cavity. The base is positioned on the hinge connector and has another opening sized and shaped to receive the fastener with the head positioned in the cavity. The insertion of the plate in the cavity secures the head of the fastener within the anti-theft device.
Claims15
An anti-theft device for a grating of a transport railcar, the grating including a grating bar and a plurality of transversely coupled rods that form a plurality of grating openings therebetween, the grating coupled to a surface of the railcar by a grating connector that comprises a connector base and a connector keeper, the grating bar disposed between the connector base and connector keeper, the anti-theft device comprising:
- a body extending over the grating connector, the body including a first end coupled to a surface of the railcar, and a second end extending beyond the grating connector and projecting through a grating opening, and the second end including a flange extending transversely to a rod forming the grating opening.
An anti-theft device for a grating of a transport railcar, the grating coupled to the railcar by a grating connector that is secured to a surface of the railcar by a fastener having a head and a shank, the anti-theft device comprising:
- a cup comprising a cup base and a cup wall that form a cavity, the cup base having an opening that is sized and shaped to receive the shank of the fastener and retain the head within the cavity, the cup wall having an outer surface comprising first and second sides, the first side forming a first angle relative to the railcar surface that is an obtuse angle facing away from the outer surface, and the second side forming a second angle relative to the railcar surface that is different from the first angle.
An anti-theft device for a grating of a transport railcar, the grating including a plurality of transversely coupled rods that form a plurality of grating openings therebetween, the grating coupled to a surface of the railcar by a grating connector, the anti-theft device comprising:
- a body extending over the grating connector, the body including a first end coupled to a surface of the railcar, and a second end projecting through a grating opening and including a flange extending transversely to a rod forming the grating opening;
- wherein the flange engages the rod forming the grating opening when the device is lifted from the grating, to prevent removal of the device.
