Patent IE-S64893-B2 (IE)
Title: Right way direction indicator
Inventor: MCWEY BRENDAN
Filed: 1994-10-14
Abstract: The Right Way Direction Indicator is an entiely new concept in road sign posting. It is designed to solve the universal problem of conventional road signs being deliberately altered thus causing major problems for road users. All of our present road signs are erected on round poles with round brackets holding the direction plate or othe signs. By applying limited pressure or because of rusting, combined with normal wear and tear the round bracket holding the sign can be relatively easy to turn on the pole leading to inaccurate directions being given. The Right Way Direction Indicator is based on the concept that if a square/rectangular pole is used instead of the traditional round pole and using a matching square/rectangular bracket to hold the desired sign, it is virtually impossible to move or alter the sign.

Abstract: A hub/tape clamp arrangement for tape-like or strip-like articles consists of a recess in the peripheral edge of the hub, having one or more middle projections, and a tape clamp having the shape of an inverted W. In practice, wedge-shaped locking means between the projection and/or walls of the recess and the tape clamp may serve to retain the clamp and fix the tape. Steps at the ends of the recess, and extensions or steps in the hub recess which have been matched up in shape, increase the possibilities for monitoring/measuring dimensions. If the tape is fastened asymmetrically on one side, the tape clamp rises out of the recess on one side by a distance precisely the same as the tape thickness, so that the tape emerging from the recess is wound at the same level, i.e. the empty hub has a roughly screw-shaped peripheral contour. The hub can be designed for use with or without one or more flanges and is particularly useful for thin tapes, e.g. magnetic tapes.
