Abstract
A handle includes a bottom wall and two side walls extending up from the bottom wall. Ribs extend between the walls and define upwardly open recesses. The smooth surfaces of the side walls and bottom wall provide a more comfortable handle for the user.
Description
BACKGROUND

The present invention relates generally to plastic handles, such as for pails.


Plastic handles, such as for pails, often include a handle portion with straps extending from either end of the handle portion. The handle portion has a larger diameter than the straps, often by including ribs extending radially outward. The ribs make the handle less comfortable for the user's hand. Sometimes the handle has one flat surface, but there is still pressure on the user's hand from ribs in the handle portion, which is not comfortable when carrying a heavy load.


SUMMARY

A handle includes a bottom wall continuous with two side walls. A plurality of ribs extend between the walls and define upwardly open recesses. These side walls and bottom wall provide a smooth surface for the main contact areas of the user's hand. Most of the weight and pressure on the user's hand will be with the smooth surfaces, not with free ends of the ribs.

DESCRIPTION OF PREFERRED EMBODIMENTS

A handle 10 according to one embodiment of the present invention is shown in FIGS. 1-6. Referring to FIG. 1, the handle 10 includes a handle portion 12 and straps 14 extending from either longitudinal end of the handle portion 12. Each strap 14 terminates in a connector portion 16, such as a standard snap-in type rotatable connector 16. The handle portion 12, straps 14 and connector 16 are integrally molded as a single piece of a polymer.



FIG. 2 is an enlarged view of the handle portion 12 of FIG. 1. As shown, the handle portion 12 includes side walls 18 and a longitudinal divider rib 20 with transverse lateral ribs 22 connecting the two side walls 18. The side walls 18, longitudinal divider rib 20 and lateral ribs 22 define upwardly open recesses 24. The recesses 24 are defined by coring in the molds, i.e. the parting line of the handle 10 can be parallel to the straps 14, i.e. perpendicular to the dividers 20, 22, with slides to form the connectors 16. Alternatively, the parting line can be perpendicular to the straps 14, with slides to form the recesses 24.


Referring to FIG. 3, the handle portion 12 further includes a bottom wall 26 continuous with the side walls 18.


Referring to FIG. 6, this provides a continuous surface for the user's hand (side walls 18 and bottom wall 26) on the main contact surfaces. The side walls 18 are more than half the height of the handle 10 and curve inwardly toward one another. The side walls 18 extend upward past a point of the maximum diameter of the handle portion 12 and then curve inward toward one another. Alternatively, the side walls 18 and bottom wall 26 can be considered one continuous wall extending circumferentially around more than 180° of the handle portion 12. This provides a more comfortable and stable handle for the user, particularly when carrying a heavy pail.


A handle 110 according to a second embodiment of the present invention is shown in FIGS. 7-10. Referring to FIG. 7, the handle 110 includes a handle portion 112 and straps 114 extending from either longitudinal end of the handle portion 112. Each strap 114 terminates in a connector portion 116, such as a standard snap-in type rotatable connector 116. The handle portion 112, straps 14 and connector 116 are integrally molded as a single piece of a polymer.



FIG. 8 is an enlarged view of the handle portion 112 of FIG. 7. As shown, the handle portion 112 includes side walls 118 and a longitudinal divider rib 120 with transverse lateral ribs 122 connecting the two side walls 118. The side walls 118, longitudinal divider rib 120 and lateral ribs 122 define upwardly open recesses. The recesses are defined by coring in the molds, i.e. the parting line of the handle 110 can be parallel to the straps 114, i.e. perpendicular to the dividers 120, 122, with slides to form the connectors 116. Alternatively, the parting line can be perpendicular to the straps 114, with slides to form the recesses.


In this embodiment, the longitudinal divider rib 120 includes a tapered portion 121 at each end of the handle portion 112, visible in FIGS. 8 and 9, that tapers continuously into a small vertical rib 115 extending substantially the entire length of the strap 114. The vertical rib 115 may project from one or both surfaces of the strap 114.


Referring to FIG. 10, the handle portion 112 further includes a bottom wall 126 continuous with the side walls 18.


The handle 110 provides a continuous surface for the user's hand (side walls 118 and bottom wall 126) on the main contact surfaces. The side walls 118 are more than half the height of the handle 110. Alternatively, the side walls 118 and bottom wall 126 can be considered one continuous wall extending circumferentially around more than 180° of the handle portion 112. This provides a more comfortable and stable handle for the user, particularly when carrying a heavy pail. The handle portion 112 would have the same cross section as FIG. 6.


In accordance with the provisions of the patent statutes and jurisprudence, exemplary configurations described above are considered to represent a preferred embodiment of the invention. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
