Michelman ABSTRACT: A plastic snap on protector for covering the protruding members of removable rims that seal drums, barrels and the like, to guard against injury.

PATENTED JUN28 |97l IN VENTUR- M RIM GUARD This invention is concerned with a protector for covering 1 the protruding-ends of a locking type rim used to seal covers on barrels or drums. Particularly, this invention solves the problem of covering, in a removable way, the protrusions of a removable rim on a drum or barrel.

It is an object of the within invention to provide an article of manufacture that is inexpensive in cost to cover the protrusions of a rim that locks covers on drums or barrels.

Another object of the within invention is to provide a guard for protrusions as aforesaid that is light in weight.

It is still a further object of the within invention to provide a streamlined shape-snap onguard to cover the protrusions on a locking rim for barrels as aforesaid.

These and other objects are obtained by providing a segment of a circle made of a plastic material wherein the interior concave surfaces conform to the dimensions of the protrusion and the upper edges thereof conform to the shape of the rim, creating a moldlike interior surface to conform to the area to be covered. In addition thereto, the plastic material is resilient and enables the device to be snapped around the rim at its edges enabling that portion of the protrusions to be covered over affording protection to persons against injury.

Reference is made to the following detailed description and, particularly to the drawings in which:

FIG. 1 is a perspective view of a barrel or drum having a locking rim set in place at the top thereof.

FIG. 2 is a perspective view of an exploded portion of the drum and rim with the guard of the within invention in place thereover.

FIG. 3 is a top plan view of the drum and rim locked into place with a bolt with the guard shown in dotted lines located over the locking mechanism of the rim.

FIG. 4 is a cross section view taken along the line 4-4 of FIG. 3 showing the guard as it is located over the locking mechanism of the rim.

FIG. 5 is a top plan view of the guard in place over the rim.

IN FIG. 1, a drum or barrel 1 has connected to its top cover a removable locking rim 3. The rim 3 has 2 extending members or protrusions 4. Located in these protrusions 4 are openings 9 adapted to receive the bolt and nut assembly 5. (See FIG. 3) It is apparent that the protrusions 4 of the locking mechanism, which are necessary to lock the lid I0 on the drum, are by their design a potential cause of injury to people who might come in contact with same.

The invention herein comprises a molded plastic guard. The guard has a lower concave surface area 7, which conforms in contour to the vertical surface to the drum I and is in a cross section a segment of a circle. The surface 7 extends outwardly to the surface 2. The surface area between 2 (as shown in FIG. 4) and 7 is diagonal. At position 2, the surface is vertical. The locus of the surface continues upwardly and bends to the horizontal and then returns to the vertical and finally to the horizontal at the flange 8. The dimensions of the protrusion surface from 7 through 2 and back to 8 are predetermined in design to accommodate the protrusions 4 of the rim 3. The surface on the inside of the area at 6 is adapted to surround the locking mechanism assembly at 4 and 5. The edges 11 of the guard-are narrowed down so as to conform to the contours of the rim 3 (See FIG. 2). The surfaces 2 bulge out from the edges in the manner previously described (See FIG. 5).

For operation, it is necessary to snap out the flange 8 with the finger in order to have the guard device lockedinto place over the protrusions 4. The user can take his finger pull out on flange 8 so that it is away from the surface 7 by either holding his finger at the bottom of 7 or by placing 7 against the barrel surface. As soon as the guard snaps into place, the user can remove his finger from the flange 8 and the guard becomes a snug fit covering the potentially dangerous protrusions 4. To remove the guard, the operator lifts up on flange 8, and pushes toward surface 7, releasing the guard from the rim 3.

I claim:

1. A molded guard device to be placed over the protrusions of the locking mechanism of a rim for sealing covers to barrels comprising a lower surface having an inner concave surface for conforming to the peripheral surface of a barrel, an intermediate surface diagonally extending upwardly and outwardly from the lower surface, a short outside substantially vertical surface extending upwardly from said intermediate surface, a substantially horizontal surface extending inwardly from said short outside vertical surface, a short inward concave vertical surface extending downwardly from said horizontal surface and a short horizontal surfacefor extending over the rim at the bottom of said short concave vertical surface, the inner surface of the edges of the upper portion of said guard being of a dimension to fit snugly about the aforesaid barrel rim.

2. A molded guard as described in claim I wherein the material forming said guard is resilient whereby the edges of said upper portion are adapted to frictionally engage said rim.

3. A molded guard as described in claim 2 wherein the lateral sides of the intermediate surface converge towards each other.

4. A molded guard as described in claim 2 wherein the edges of the said lower surface, the said intermediate surface, the said outside vertical surface, the said inside vertical surface, and the said short horizontal surface are narrowed down from their respective surfaces to form an edge for conforming to the contour of the outer edges of the said rim.

5. A molded guard as described in claim 1 wherein the lateral sides of the intermediate surface converge towards each other.

6. A molded guard as described in claim 5 wherein the edges of the said lower surface, the said intermediate surface, the said outside vertical surface, the said inside vertical surface, and the said short horizontal surface are narrowed down from their respective surfaces to form an edge for conforming to the contour of the outer edges of the said rim.

7. A molded guard as described in claim 1 wherein the edges of the said lower surface, the said intermediate surface, the said outside vertical surface, the said inside vertical surface, and the said short horizontal surface are narrowed down from their respective surfaces to form an edge for conforming to the contour of the outer edges of the said rim.
