Abstract: The present perforated floor mat holder is for securing perforated rubber floor mats on a wet and slippery floor. It is comprised of an elongated strip with studs arranged at regular intervals that match the spacing of the holes on the floor mat. The strip is fastened to a floor with screws inserted through mounting holes arranged along the strip. The floor mat is positioned on the strip with the hole around the studs. The stress applied to the rims of the holes by the studs are spread among a relatively large number of holes, so that the rims resist being torn by the studs. Transverse grooves arranged several studs apart on the strip enable the strip to be broken into shorter sections of a predetermined minimum length. In a first embodiment, one mounting hole is arranged between each pair of adjacent studs.

Abstract: There is provided a mat having multiple sets of pins, each set of pins being located within surrounding, characterized in that the pins do not extend significantly beyond the highest point of the surrounding. Thus the pins are protected by the surrounding and are less likely to break after extended use. The mat may be provided with areas adapted for the receipt of strips of textile materials, eg carpeting which advantageously has a hard-backing and is able to snap into the areas provided. The inclusion of the textile material combines a scraping function together with the visual appearance of a carpet. The strips of textile material will be separated by sets of pins as described above. A set of such mats is also described.

Abstract: A structure for trapping hazardous dust in a work place which also serves as a walkway is disclosed. A removable cover member (12) includes a frame and a central support member (18), the frame and central support member (18) being covered with expanded metal mesh (22). The cover rests upon a shallow pan (10), the pan (10) having a raised central ridge (28) which is aligned with the central support member (18) in the cover (12) when the cover (12) is placed on the pan (10). The central support member (18) and the central raised ridge (28) cooporate to limit the deflection of the expanded metal mesh (22) under the weight of a user. The lower pan (10) is provided with a hook (34), for engaging other similar pans (10) for assembling a walkway or other desired configuration of dust collecting pans. The pan may be filled with a non-evaporating liquid to permanentaly retain dust falling into the pan, and also dust being scraped from the shoes of a user by the expanded metal mesh.

Abstract: Welding splatter shield comprised of fire-resistant flexible sheet material such as fiber glass overlaid with a heat conducting metal mesh. The metal mesh may be secured around the edges of the sheet by sewn flanges and may overlay on both sides of the flexible panel if desired.
