US Patent 7086521 Adjustable lane guide

An adjustable lane guide system comprising: 1) first and second generally parallel and spaced apart support bars; 2) a plurality of lane guides generally perpendicular to the support bars; and 3) a plurality of adjustable attachment mechanisms joining the lane guides to the first and second support bars. Each of the adjustable attachment mechanisms comprises a bearing block that engages the support bars; a pair of opposing wings on either side of the bearing block also engaging the support bars and each having first and second ends, the first ends hingeably attached to the bearing block and the second ends flared by a spring located between the pair of opposed wings such that pressure applied to each of the second ends causes the wings to be drawn toward each other against the pressure of the spring thereby allowing the adjustment mechanisms to move laterally along the support bar so that the distance between adjacent lane guides can be changed along the first and second support bars.
