May 2, 1967 G. M FAUL DETACHABLE' HANDLE Filed April 30, 1965 FIG! FIGB

INVENTOR GEORGE MC FAUL ATTO RN EY United States Patent 3,317,232 DETACHABLE. HANDLE George McFaul, 1095 High St., Dedham, Mass. 02026 Filed Apr. 30, 1965, Ser. No. 452,151 4 Claims. (Cl. 294-33) This invention rel-ates to a detachable handle for containers.

The invention has for an object to provide a novel and improved detachable handle for containers characterized by structure enabling the handle to be resiliently snapped into engagement with the ends of the container in a manner such as to provide a firm and rigid attachment thereto not subject to rocking or wobbling and which may be quickly and easily detached from the container.

The invention has for a further object to provide a novel and improved detachable handle of the character specified characterized by structure such as to provide a balanced unitwhen the handle attached to the container is grasped by the user.

With these general objects in view and such others as may hereinafter appear, the invention consists in the detachable handle as hereinafter described and particularly defined in the claims at the end of this specification.

, In the drawings illustrating the preferred embodiment of the invention:

: FIG. 1 is a side elevation partly in cross section of the present detachable handle attached to a metal container;

FIG. 2 is a perspective view of the handle;

FIG. 3 is a plan view of the handle; and

FIG. 4 is a plan view of a modified form of the pres ent handle.

In general, the present invention contemplates a detachable handle for containers and particularly cylindrical metal containers having crimped end portions forming extended rims and providing annular grooves adjacent the edges thereof such as the structure provided at the ends of a conventional one-quart paint can. The present detachable handle is arranged to be easily and quickly snapped into assembled relation with the ends of the can, one end of the handle being engaged over the rim and into the annular groove at the top of the can, and the other end of the handle being arranged to embrace the rim at the bottom of the can in a manner such as to provide a firm and rigid attachment not subject to being displaced during use.

The illustrated handle comprises a one-piece sheet metal strip bent and stamped to provide upper and lower can engaging portions, the sheet metal being of substantial rigidity but having sufliciently flexibility or elasticity to permit the handle to be resiliently snapped into position to clamp the can between the ends of the handle. The present handle is also constructed so that the body of the handle extends at an angle relative to the central axis of the can whereby to provide a substantially balanced assembly which enables the unit to be held comfortably in the hand in a natural position when in use.

Referring now to the drawings and particularly to FIG. 1, represents the present detachable handle shown as attached to a metal container -12, such as a cylindrical metal paint can having crimped or inwardly folded edges at the top and bottom ends thereof providing

extended rims

13 and 15, respectively, at each end of the can. The can is also provided with an annular grooved portion 14 adjacent the top or upper edge of the can and an annular grooved portion 16 adjacent the lower or bottom edge of the can. 7

The handle 10 is generally U-shaped having a body portion 18 and upper and

lower legs

20, 22, respectively, and in practice may comprise a one-inch wide flat strip of about 16-gauge sheet metal with the

legs

20, 22 bent substantially at right angles to the body portion 18 as shown. The upper leg 20 is provided with two spaced depending ears or prongs 24 stamped out of the edges of the free end of the leg and bent downwardly, as illustrated, leaving an intermediate forwardly extended portion 25- which may be bent upwardly at a slight angle as shown. The depending ears 24 are of a length such as to extend over the rim 13 and into the grooved portion 14 at the upper end of the can as shown in FIG. 1.

The lower leg 22 of the handle 10 is longer than the upper leg 20 for a purpose to be described and is arranged to be snapped into engagement with the extended rim .15 of the crimped end portion defining one wall of the annular grooved portion 16 at the bottom of the can. As herein shown, a portion adjacent the free end of the lower leg 22 is bent upwardly at a small angle as indicated at 28, and the extreme end of the leg is bent downwardly at a small angle as indicated at '30 providing a lip to facilitate sliding engagement of the free end of the leg with the bottom of the can. The angular portion 28 is provided with a medially disposed upset portion comprising a retaining lug 32 which is stamped out of the metal and bent upwardly as shown for engagement with the inner wall of the rim 15, and the straight portion of the leg 22 is provided with spaced upwardly bent stop lugs 34 stamped from the edges of the leg 22 and bent upwardly at about 45 to engage the outer wall of the can. The relationship between the end of the retaining lug 32 and the ends of the stop lugs 34 is such that the can is firmly held therebetween in a manner such as to prevent displacement of the can relative to the handle. It will be understood that the sheet metal material provides a substantially rigid handle but has sufficient resilience so that when the lower leg 22 is pushed into engagement with the bottom rim 15 the leg will flex downwardly until it rides over the retaining leg 32 whereupon the leg will flex upwardly into clamping engagement with the bottom of the can. It will be understood that the distance between the legs is proportioned relative to the height of the can to permit a snap action engagement when assembled with the can.

From the description thus far it will be seen that in operation the depending ears 24 of the upper leg 20 are first fitted into the annular grooved portion 14, and the lower leg 22 is then engaged with the lower rim 15 and pushed inwardly until the retaining lug 62 snaps into position in the grooved portion 16 and engages the inner wall of the rim 15. -It will be seen that the retaining lug 32 is bent upwardly at a small incline to provide in effect a cam surface which will ride over the rim 15 during application of the handle to the can and then permit upward flexing of the leg as described. It will be understood that the ends of the stop lugs 34 engage the side wall of the can at about the same time that the retaining lug 32 clears the bottom of the rim to engage the inner wall thereof so that the rim 15 is embraced between the lug 32 and lugs '34. In order to detach the handle the tip of the finger or thumb may be inserted under the lip 30 to flex the leg downwardly until the retaining lug '32 is released from the rim 15 whereupon the leg may be pulled away from the bottom of the can and the depending ears 2 4 lifted out of the grooved portion 14 in the top of the can.

As illustrated in FIG. 1, it will be noted that by making the lower leg 22 longer than the upper leg 20 disposes the body portion 18 of the handle at an outwardly and downwardly inclined angle with respect to the vertical wall or central axis of the can 12. In practice, it was found that this angle contributed to ease of handling and balancing of the can in a vertical position when the body portion is grasped with the fingers and the thumb placed at the intersection of the base portion with the upper leg. It will be noted that the legs are bent at about a one-half inch radius, the upper radius forming a thumb rest as indicated at 36.

The body portion 18 of the handle is provided with an indented or inwardly curved portion, concave in cross section as indicated at 38, to provide a comfortable gripping portion for the hand and also to afford rigidity to the handle. In practice, advertising material or the makers name may be printed within the indented portion.

Referring now to FIG. 4, in a modified form of the present detachable handle, the lower leg 22 may be extended and bifurcated as illustrated to provide two angularly spread or forked legs 40 which may extend across the bottom of the can to provide a greater support area.

From the above description it will be seen that the present detachable handle comprises a one-piece metal member bent and stamped to engage the ends of a container having extended rim portions in a manner such as to be capable of being resiliently snapped into position to provide a rigid attachment and which may be quickly and easily detached from the container. In practice, the sheet metal handle may be galvanized, tinned or otherwise treated. It will be apparent that the present detachable handle may be used and reused for other similar cans having crimped or rimmed end portions and is not limited to use with paint cans.

While the preferred embodiment of the invention has been herein illustrated and described, it will be understood that the invention may be embodied in other forms within the scope of the following claims.

Having thus described the invention, what is claimed is:

1.
