Cleaning device for shower enclosure tracks

Claim 2

In a cleaning device particularly suited for use in removing encrusted residue from metallic surfaces exemplified by the surfaces of channel shaped tracks formed of aluminum and provided for supporting sliding doors defining an enclosure for a shower, the improvement comprising: A. an elongated handle characterized by a depth greater than the width thereof having an elongated slot extended along one surface and characterized by a cross section of a T-shape configuration, and a detent disposed in axial alignment with said slot for receiving a locking protuberance; and B. a scouring body suitably dimensioned to be received by the tracks for removing residual encrustation from said metallic surface comprising an elongated backbone characterized by a portion having a cross section of T-shape configuration and adapted to be inserted axially into said slot, means including a locking protuberance projected from said backbone and adapted to be received by said detent for securing the backbone against axial displacement relative to said slot, and a pad of pressed polyester fiber adhered to said backbone and projecting therefrom.

Claim 3

An improved cleaning device particularly suited for use in removing encrusted residue from metallic surfaces exemplified by the surfaces of channel shaped tracks formed of aluminum and provided for supporting sliding doors defining an enclosure for a shower comprising: A. an elongated handle characterized by a depth greater than the width thereof having an elongated slot extended along one surface and characterized by a cross section of a T-shape configuration, and a detent disposed in axial alignment with said slot for receiving a locking protuberance; B. interchangeable components including a scraper unit for fracturing encrustation deposited on a metallic surface comprising an elongated first backbone characterized by a portion having a cross section of T-shape configuration adapted to be inserted axially into said slot, means including a locking protuberance projected from one surface of said first backbone and adapted to be received in said detent for securing the first backbone of said scraper against axial displacement relative to said slot, and a rigid foot angularly projecting from the first backbone including an inclined face adapted for use in forcibly penetrating said encrustation; C. a scouring body for removing residual encrustation from said metallic surface comprising an elongated second backbone characterized by a portion having a cross section of T-shape configuration and adapted to be inserted axially into said slot, means defining a locking protuberance projected from said second backbone and adapted to be received in said detent for securing the second backbone against axial displacement relative to said slot, and a pad of pressed polyester fiber adhered to said second backbone and projecting therefrom; and D. a bristle brush for polishing said metallic surface comprising a third backbone characterized by a portion having a cross section of T-shape configuration and adapted to be inserted axially into said slot, means including a locking protuberance adapted to be received in said detent for securing the brush against axial displacement, and a plurality of bristle tufts projecting from said third backbone.

Claim 4

An improved cleaning device particularly suited for use in removing encrusted residue from metallic surfaces exemplified by the surfaces of channel shaped tracks formed of aluminum and provided for supporting sliding doors defining an enclosure for a shower comprising: A. an elongated handle characterized by a depth greater than the width thereof having an elongated slot extended along one surface and characterized by a cross section of a T-shape configuration, and a detent disposed in axial alignment with said slot for receiving a locking protuberance; B. interchangeable components including a scraper unit for fracturing encrustation deposited on a metallic surface comprising an elongated first backbone characterized by a portion having a cross section of T-shape configuration adapted to be inserted axially into said slot, means including a locking protuberance projected from one surface of said first backbone and adapted to be received in said detent for securing the first backbone of said scraper against axial displacement relative to said slot, and a rigid foot angularly projecting from the first backbone including an inclined face adapted for use in forcibly penetrating said encrustation; C. a scouring body for removing residual encrustation from said metallic surface comprising an elongated second backbone characterized by a portion having a cross section of T-shape configuration and adapted to be inserted axially into said slot, means defining a locking protuberance projected from said second backbone and adapted to be received in said detent for securing the second backbone against axial displacement relative to said slot, and a pad of pressed polyester fiber adhered to said second backbone and projecting therefrom; and D. a bristle brush for polishing said metallic surface comprising a third backbone characterized by a portion having a cross section of T-shape configuration and adapted to be inserted axially into said slot, means including a locking protuberance adapted to be received in said detent for securing the brush against axial displacement, and a plurality of bristle tufts projecting from said third backbone.

Claim 5

The device of claim 2 wherein said handle includes means defining an abutment shoulder in juxtaposition with one end of said slot and each of said backbones includes a projection including a face adapted to engage said shoulder.
