    Abstract: A urinal screen assembly for disposition adjacent the drain of a urinal is disclosed. The screen assembly includes feet or risers depending from the lower surface to maintain a spaced relation between at least the marginal edge of the assembly to allow liquid to flow therebetween and simultaneously prohibit the passage of unwanted solid materials. The main body portion of the screen assembly is provided with a plurality of tapered apertures which provide fluid communication therethrough and minimizes splash-back caused by an impinging stream of urine.

  • Patent number: 5343589
    Abstract: A lobby dust pan of the type generally having a receptacle portion pivotally connected to a yoke. The yoke is flexible and is connected to a shaft. The yoke is deformable to enable latching means thereon to be retained with or released from a slot on the receptacle. The shaft in turn is connected to a novel handle having an axially extending body portion, a connecting portion formed proximate one end of said body portion and connected to the upper end of the shaft, and a transverse downwardly extending ridge portion formed at the other end of said body portion. The novel ridge portion of the handle permits the lobby dust pan to easily be carried over the arm of the user when moving from job to job, thus freeing the hands for other purposes. Also, it allows the lobby dust pan to be "hooked" over receptacle containers when temporarily not in use.
