Replaceable blade assembly

A replaceable blade assembly includes an arm that may be coupled to a lawn mower. A blade is removably coupled to the arm so the blade may be moved by the arm. A clip is removably coupled to the arm so the clip may retain the blade on the arm.

BACKGROUND OF THE DISCLOSURE

Field of the Disclosure

The disclosure relates to replaceable blade devices and more particularly pertains to a new replaceable blade device for quickly replacing a cutting edge on a blade.

SUMMARY OF THE DISCLOSURE

An embodiment of the disclosure meets the needs presented above by generally comprising an arm that may be coupled to a lawn mower. A blade is removably coupled to the arm so the blade may be moved by the arm. A clip is removably coupled to the arm so the clip may retain the blade on the arm.

DESCRIPTION OF THE PREFERRED EMBODIMENT

As best illustrated inFIGS. 1 through 5, the replaceable blade assembly10generally comprises an arm12that may be rotatably coupled to a lawn mower14of any conventional design. A centrally positioned shaft aperture16extends through a top surface18and a bottom surface20of the arm12. The shaft aperture16may insertably receive a shaft22on the lawn mower14so the lawn mower14may rotate the arm12. The arm12may have a length between 61 cm and 91 cm.

A first lateral edge24of the arm12is bent so a plurality of first tabs26is formed proximate a first end28of the arm12. A second lateral edge30of the arm12is bent so a plurality of second tabs32is formed proximate a second end34of the arm12. The plurality of the first26and second32tabs is spaced apart on the associated ones of the first24and second30lateral edges of the arm12. Additionally, the plurality of first26and second32tabs alternately extends upwardly and downwardly from the associated one of the first24and second30lateral edges of the arm12. The plurality of first26and second32tabs may each have a height between 6.5 mm and 12.5 mm.

A blade36comprises a coupling portion38that has a C-shape. The coupling portion38of the blade36may insertably receive the first26or second32tabs so the blade36is retained on the arm12. A cutting portion40of the blade36is coupled to and extends forwardly from the coupling portion38of the blade36so the cutting portion40of the blade36may cut grass42when the blade36is moved by the arm12. The blade36may have a length between 7.5 cm and 20 cm. The blade36is one of a pair of blades36that are each positionable proximate an associated one of the first end28and the second end34of the arm12. A first end35of the cutting portion40of the blade36may be angled outwardly with respect to a first lateral side37of the blade36.

A clip44has a C-shape so the clip44may engage the first lateral edge24and the second lateral edge30of the arm12. The clip44is positionable on the top surface18of the arm12so the clip44is removably coupled to the arm12. In addition, the clip44abuts the blade36when the clip44is removably coupled to the arm12so the clip44may retain the blade36on the arm12. The clip44is one of a pair of clips44that are each positionable proximate an associated one of the pair of blades36. Each of the pair of clips44may engage an associated one of a pair of clip grooves46each extending inwardly from an associated one of the first24and second30lateral edges of the arm12.

In use, the assembly10allows for a method48of replacing a blade. The steps of the method48comprise a step50of providing the arm12comprising the first lateral edge24, the second lateral edge30, the first end28and the second end34, the plurality of the first26and second32tabs coupled to the arm12, the pair of blades36comprising the coupling38and the cutting40portions and the pair of clips44. The method48also includes a step52of positioning a selected one of the first24or second30lateral edges of the arm12within the coupling portion of a selected one of the pair of blades36. The method48further includes a step54of sliding the selected one of the blades36toward the associated one of the first28and second34ends of the arm12so the associated ones of the plurality of the first26and second32tabs is positioned within the coupling portion38of the blade36. Finally, the method48includes a step56of coupling a selected one of the pair of clips44to the arm12proximate the selected one of the blades36so the clip44retains the selected one of the blades36on the arm12.
