There is provided a dust suction apparatus comprising: a base; a side frame wherein the base and frame defines a dust suction space; a dust suction panel disposed in the dust suction space; and a dust-collection device air-communicated with the dust suction panel, wherein the dust suction panel includes a plurality of dust suction panel modules, wherein the dust suction panel modules are mounted in the dust suction space in a modular fashion to allow the plurality of dust suction panel modules to be removed individually.

One aspect of the invention provides an extruded, polymeric underlayment pad including: a substrate; a first plurality of at least four intersecting ridges extending perpendicularly from a first side of the substrate; and a second plurality of at least four intersecting ridges extending from a second side of the extruded polymeric substrate.

The present invention is an ergonomic safety work mat which includes a modular ergonomic wooden platform with a synthetic tapered marginal border. The purpose of this invention is to provide occupational workers with a therapeutic, forgiving work surface to protect them from the health risks of working, walking and standing on a concrete floor or common anti-fatigue mat used in many factories today. The wooden platform is raised off the floor to offer suspension, thus promoting a spring effect for absorbing and returning compression force resulting in reduced stress loads and compression force for people who work, walk or stand fort extended periods of time. This product is modular in design so that the tapered borders of separate modular sections connect for a snug fit. The vertical edges of the wood sections also have connection points that provide a leveling effect and further enhance the fit of the module sections.

A shoe disinfecting device has a base and a lid defining an interior compartment to hold liquid disinfecting solution. The lid is upwardly biased (e.g., spring loaded) from a compressed position to an extended position and includes openings for passage of solution between the interior and a lid upper surface. Pressurization of the solution within the interior, responsive to forces depressing the lid from the extended to the compressed position, causes expelling of the solution through the openings and onto the upper surface. Upon release of the depressing force, biasing of the lid from the depressed to the extended position creates a vacuum within the interior and pulls remaining solution from the upper surface back into the interior. A removable disinfecting liquid container is in fluid communication with the interior via a liquid pump controlled to pump solution from the container to maintain sufficient quantities of solution within the interior.

A mat comprises a profile bar, a metal strip with a high coefficient of friction, a U-clip, and a rivet rod is disclosed. The profile bar includes a head with a flat surface and a post including a hole. The metal strip includes a surface with a high coefficient of friction, and a plurality of posts opposite the surface with the high coefficient of friction, wherein the plurality of posts includes a hole. The rivet rod fits through the hole in the post of the profile bar and the hole of the plurality of posts of the metal strip. The U-clip includes notches, and the post of the profile bar rests in one of the notches while the plurality of posts of the metal strip rests in several of the notices. The rivet rod extends through the holes to couple the profile bar and the metal strip to the U-clip.

A work mat on which a worker stands while operating a machine for comfort and for the purpose of easing of physical stress caused by standing on a non-compressible floor during a work day. The work mat includes a wooden platform with a peripheral synthetic border which tapers from the floor up to the top edge of the wooden platform. In addition, the synthetic border extends inward about one half inch under the peripheral edge of the wooden platform, thereby elevating the wooden platform above the floor. The wooden platform is therefore suspended over the floor and can flex up and down as a user walks on or stands on the mat, thereby absorbing some of the shock of walking and moving on the floor. The compressibility of the wooden platform adds to the comfort of the work mat as well.

Device for cleaning of footwear in connection with use of construction site vehicles, with a water pump (16), nozzles (20) and water pipe (18) between same. The device includes a compressor (22) for air and air pressure pipe (23) and nozzles (20, 21), an outer supporting structure in the form of a housing (2) arranged to protect the other parts of the device against external influence, The housing includes a recess (14) for receiving footwear to be cleaned. At least one sensor (25) is included for initiating cleaning when footwear is positioned in said recess (14). The device is arranged to automatically flush the footwear with water via the water pump (16) and immediately thereafter to blow the footwear dry with air from the compressor (22).
