Abstract

A floor sweeper having an improved pivotal means for a handle is disclosed. The pivotal means comprises a main body having a concave portion thereon, a holding member having bearing apertures and a leaf spring positioned in a predetermined seat of the concave portion of the main body, wherein the handle is pivotally supported to swing in a desired angle such that shaft members of the handle are received in the bearing apertures of the holding member and base end of the handle is pressed upward by the leaf spring.

Claims

1. An improved pivot arrangement for a handle of a rotary floor sweeper comprising:

a main body portion of said sweeper having a first concave portion in the center of the top thereof;

a handle member and two shaft members at the base of said handle member projecting orthogonal to the axis of said handle member;

holding member means removably fitted into said first concave portion of said main body and fitted around said shaft members on said handle for pivotally affixing said handle to said main body;

said main body having a second concave portion beneath said handle member held in said first concave portion by said holding member means; and

a leaf spring means removably fitted into said second concave portion and biased toward and engaging said handle member for tightly holding said handle member in said holding member means.

2. an improved pivot arrangement as claimed in claim 1, where in said holding member means has lugs extending from one end thereof inserted into slits formed in said main body portion;

and

fixing screws are screwed through said main body portion into said holding member means.

3. An improved pivot arrangement for a handle of a rotary floor sweeper comprising:

a main body portion of said sweeper having a concave portion in the center of the top thereof;

a handle member and two shaft members at the base of said handle member projecting orthogonal to the axis of said handle member;

holding member means removably secured and fitted into said concave portion of said main body and fitted around said shaft members on said handle for pivotally affixing said handle member to said main body portion; and

leaf spring means removably fitted into the bottom of said holding member means and biased toward and engaging said handle member in said holding member means for tightly holding said handle member therein.
