Abstract: A portable apparatus for testing slip resistance of surfaces such as floors and bathtub surfaces operated by applying a pad of friction material to the surface and instantaneously applying a load to the pad at a selected angle. The load is applied by releasing a weight carried atop an articulated linkage on the bottom of which the friction pad is attached. The linkage slides in a frame which can be set at selected angles on a base, and a trigger bar mounted in the frame interacts with a rod of the articulated linkage to hold and release the weight.

Abstract: A portable apparatus for testing the slip resistance of surfaces such as floors and bathtub surfaces operates by applying a load instantaneously to a pad of friction material resting on the surface at a selected angle of attack. An articulated linkage carrying the pad is set at a predetermined angle and the load is substantially instantaneously applied to determine whether the pad slips at the preset angle. Tests may be successively conducted at different angles of the linkage or a single go, on-go test may be conducted at a datum angle. The articulated linkage is carried on a pivoted frame which moves across a segment plate to establish the predetermined angle. A pawl and tooth type latching system holds the frame relative to the plate at the preset angle.

An articulated linkage carrying the pad is set at a predetermined angle and the load is substantially instantaneously applied to determine whether the pad slips at the preset angle. Tests may be successivley conducted at different angles of the linkage or a single go, no-go test may be conducted at a datum angle. The articulated linkage is carried on a pivoted frame which moves across a segment plate to establish the predetermined angle. A pawl and tooth type latching system holds the frame relative to the plate at the preset angle.

Abstract: A portable testing device for determining the static coefficient of frict between a floor surface and a shoe sole or heel material includes an upper, weighted strut movable within a vertical plane and a lower strut pivotably secured to the bottom portion of the upper strut. The upper strut is mounted within a bearing block which is translatably movable within a horizontal plane, and the lower strut has secured to the bottom portion thereof a yoke within which a metal shoe carrying a representative shoe sole or heel material to be tested is pivotably secured. The yoke and shoe project through the base of the device framework so as to rest upon the flooring material being tested, and a trigger is disposed near the shoe so as to be actuated thereby upon the occurrence of slip between the shoe and flooring materials.
