2 Claims. (Cl. 15-216) This inventionrelates to scraping tools and particularly to a tool for scraping the corrugated sole of a shoe having parallel rows of ribs extending thereacross.

It is one object of the invention to provide a scraping tool for scraping or cleaning dirt, and the like, accumulating between parallel rows of ribs extending across the corrugated 'sole of a shoe.

It is another object of the invention to provide a tool having a scraping head with a plurality of teeth having a profile complementary to the profile of parallel rows of ribs extending across the corrugated sole of a shoe so that the teeth of the scraping head can be closely fitted or meshed with the ribs and movedparallel thereto to scrape away dirt, and the like, that may accumulate between the ribs.

It is a further object of the invention to provide a scraping device adapted to be secured to a door mat or to a porch floor in position to enable a person to scrape or clean dirt, or the like, accumulated between the parallel rows of ribs extending across the corrugated sole of a shoe.

It is a further object of the invention to provide a scraping tool for cleaning the sole of a shoe having parallel rows of ribs which is simple in construction, economical to manufacture, light in weight and effective in use.

Other objects and features of novelty of the invention will be specifically pointed out or otherwise become apparent when referring, for a better understanding of the invention, to the following description taken in conjunction with the accompanying drawings wherein:

FIGURE 1 is a plan view of a scraping tool embodying features of the present invention;

FIG. 2 is a reduced view of the scraping tool of'FIG. 1 in position to clean the sole of a shoe having ribs extending thereacross;

FIG. 3 is an enlarged fragmentary view of the scraping tool and shoe of FIG. 2 looking in the direction of the v CA-17; FIG. 4 is an enlarged sectional view of the structure illustrated in FIG. 3 taken along the line 33 thereof;

FIG. 5 is an end view of another embodiment of the scraping device of the present invention secured to a flat concrete surface;

FIG. 6 is a fragmentary view of the structure illustrated scraping head 10 and are adapted to fit closely between ribs 18 of a sole 20 of a shoe 22.

As most clearly illustrated in FIGS. 2 and 4, it will be observed that spaces 13 and 15 between the teeth 12 and 14 and 14 and 16 respectively, have the same configuration or profile as the ribs 18 and that the teeth 12, 1d and 16 have substantially the same profile as the spaces between the ribs. Stated otherwise, it may be said that the profile of the teeth 12, 14 and 16 is complementary to the profile of the ribs 18 so that theteeth can mesh with the ribs as illustrated in FIGS. 2 and 4, and the scraping tool can be moved transversely across the corrugated sole of the shoe parallel to the direction in which the ribs extend as indicated by the arrow B of FIG. 3 to scrape away any dirt, or the like, accumulating between the ribs.

The scraping tool 6 may be made from any fairly rigid or stiif material such as plastic or metal, for example, and is small and light in weight so that it can be readily carried in ones pocket. A hole 24 is also provided in the end of the handle 8 to enable the tool 6 to be carried on a key chain if desired. It will be observed that the entire tool is also formed in a slanted fashion wherein the teeth and handle portion 8 of the tool extend generally in the same direction that ribs 18 extend as most clearly illustrated in FIG. 2 to make the tool easier to use. More specifically, the scraping head 10 is wider than the handle 8 and both the handle and the teeth 12, 14 and 16 project at an acute angle from the scraping head, the acute angle being approximately the same as the acute angle at which the ribs 18 project from the sole 20.

Another embodiment of the scraping tool is illustrated in FIGS. 5 and 6 which comprises an elongated scraping device 28 having a vertical leg 30 with a plurality of teeth 26 similar to the teeth of the scraping tool 6 formed on the upper edge thereof, and a horizontal leg 32 which may be secured directly to any convenient surface 34,

such as a concrete porch floor or step, for example, by

bolts 35 or the like. With this construction, the scraping device 28 can be rigidly fixed on a porch or step to enable a person to quickly clean the corrugated sole 20 of his shoes before entering a house or building.

As illustrated in FIG. 7, a number of the scraping devices 28 can be secured together by a suitable bolt 40 with the vertical legs 30 projecting upwardly through a conventional door mat 38, or the like. Spacers 42 may be disposed between each of the vertical legs to accurately space the scraping devices 28. With this construction, the scraping devices 2? are securely clamped to the door mat 38 between the horizontal legs 32 of each scraping device which engage the under side of the door mat, and the spacers 4-2 which engage the upper side of the mat. With this arrangement, the plurality of scraping devices form a portion of the surface of the door mat to enable a person wearing the corrugated sole shoe illustrated in FIG. 2 to merely step on the portion of the door mat formed by the plurality of devices 28 and quickly clean the corrugated sole by shifting the shoe laterally across the teeth on the upper edge of the vertical legs 30. Of course, each of the teeth on each of the legs 30 would have to be laterally aligned with one another, and the vertical legs 39 would preferably be as long as a normal shoe, and preferably be spaced closely together so that several of them would fit beneath the sole of the shoe at one time.

While it will be apparent that the embodiments of the invention herein disclosed are well calculated to fulfill the objects of the invention, it will be appreciated that the invention is susceptible to modification, varation and change without departing from the proper scope or fair meaning of the subjoined claims.

What is claimed is:

1. A scraping tool for cleaning the corrugated sole of a shoe having parallel rows of ribs comprising a substantially flat body having a handle with a scraping head on one end thereof, said head having at least three teeth projecting therefrom in the plane of said body, said teeth having substantially the same profile as the spaces between said ribs and the spaces between said teeth having substantially the same profile as said ribs, said teeth projecting from said scraping head at an acute angle relative thereto and said handle projecting in the opposite direction from said head at an acute angle thereto and in a direction substantially parallel to the direction in which said teeth project whereby said teeth are adapted to extend between and mesh with the ribs and scrape the ribs clean when the tool is moved in a direction parallel to the direction in which the ribs extend.

2. In combination with a door mat, a plurality of scraping devices for cleaning the corrugated sole of a shoe having parallel rows of ribs comprising an elongated body having an angle-shaped cross section with a vertical leg and a horizontal leg, a plurality of teeth formed on the upper edge of each of said vertical legs having substantially the same profile as the spaces between said ribs and the spaces between said teeth having substantially the same profile as said ribs, said teeth projecting from the upper edge of each of said vertical legs at an acute angle relative thereto, said mat having a plurality of parallel spacedapart slots therein, each of said vertical legs projecting upwardly through one of the slots in said door mat and each horizontal leg engaging the under side of the mat and abuttingly engaging the adjacent horizontal legs, and fastening means connecting each of said vertical legs together in fixed spaced relation and in a manner to cooperate with the horizontal legs to lock the scraping devices to the door mat and to prevent relative movement between the legs.
