Drafting Board Security Cover

Work in progress on a drafting board is secured from undesired view when not in use by a locked cover.

Two rigid bars are retained at opposite ends of a flexible, non-elastic, water repellent cover. The cover is fixed at one end by blind fasteners attaching the cover to the board or to a spring-loaded take-up reel. An end lock is hooked through an eye extending through a grommet in the cover to secure it at the opposite end. The front and back of the cover are secured by a cable which is attached to a grommet at the back of the cover, wrapped under the board and then locked by a loop through a front grommet.

Once the cover is fully extended and locked, unauthorized viewing of the work under the cover is very difficult. The bars prevent the cover corners from being lifted. If a take-up reel is used, it must be fully rotated to its final stop position. Or, the take-up reel may be ratchet operated in the manner of an automobile seat belt, so that an extended cover must be retracted before it can be extended again.
