Abstract: A device designed to cooperate with the hanging hooks of a drying rack includes a levered suction cup whose body, in the shape of a circular dome, has an extension parallel to one diameter and a plane end face substantially perpendicular to the surface against which the suction cup is applied. The device further includes a transverse, rectilinear mounting bar with a plane central supporting surface that abuts the end face of the extension of the body and a mounting structure for attaching the bar to the extension of the suction cup body.

Abstract: A portable device for monitoring the wear of a tire and the geometry of a wheel set of a vehicle has a probe for measuring a depth of each tread groove of a tire, a display, a symbolic representation of a set of wheels, and indicators. The device includes a control system for processing and calculating measurements, reference values and compared values relating to rate of wear and the condition of the geometric state of the tire. Resulting calculations and comparisons are displayed on the display and indicators are activated based on the calculations and comparisons made.
