Detachably attachable implement scraper

Abstract

An implement scraper provides a scraper bar for scraping debris into a bucket, such as a five-gallon bucket, and is detachably attachable to the bucket by a bucket coupler. The bucket coupler is configured with a latch that rotates to secure the implement scraper to the rim of the bucket. The latch may be pivotably coupled between a latch pivot aperture. A rim extension is configured to extend along a rim of the bucket and the scraper bar is coupled to the rim extension and may extend across an extension angle of the bucket. A debris aperture is formed between the scraper bar and the rim extension to allow debris to fall therethrough into the bucket. A magnetic coupler is configured to retain a metallic implement to the implement scraper by one or more magnets.

(22) Certain exemplary embodiments of the present invention are described herein and are illustrated in the accompanying figures. The embodiments described are only for purposes of illustrating the present invention and should not be interpreted as limiting the scope of the invention. Other embodiments of the invention, and certain modifications, combinations and improvements of the described embodiments, will occur to those skilled in the art and all such alternate embodiments, combinations, modifications, improvements are within the scope of the present invention.

(23) As shown in FIG. 1, an exemplary implement scraper 17 has a bucket coupler 14 for detachably attaching the implement scraper to the bucket 20. The bucket coupler has a latch 60 with a latch handle 64 that rotates about a latch pivot 62 to secure the latch lock 66 on the latch end 65 against the bucket, such as against the top rim 24 of the bucket. The implement scraper is configured with the scraper bar 70 extending across the top opening 21 of the bucket. The scraper extends from the right end 73 coupled with right rim extension to the left end 71 coupled with the left rim extension 74 and forms a debris aperture 75 between the scraper blade and the interior surface 27 of the wall 25 of the bucket 20 to allow the debris to fall therethrough, down into the bucket. The rim extension has an interior flange configured down along the interior of the bucket and an exterior flange 52 configured down over the exterior of the top rim of the bucket. This rim extension forms a rim slot that extends over the top rim of the bucket. The implement scraper is configured with magnetic coupler 77 having magnets 78 for retaining a scraper implement having metallic portions, such as a metallic trowel, to the implement scraper.

(24) Referring now to FIGS. 2 and 3, a scraper implement 97 is secured to the implement scraper 17 by the magnetic coupler 77. The scraper blade 98 of the scraper implement is metal, a magnetic implement, and is retained to the magnets 78 of the magnetic coupler. A worker may place a trowel on top of the magnetic coupler of the implement scraper while performing other tasks associated with the job. This protects the trowel from falling into the mixed compound in the bucket. Also shown in FIGS. 2 and 3 is the rim extension having a rim slot 54 formed by the interior flange 50, the rim extension top 53 and the exterior flange 54. The rim slot is configured with a radius of curvature to enable the implement scraper to be placed and retained over the top rim of the bucket.

(25) As shown in FIG. 4, a scraper implement 97 is scraping debris 99 off of the scraper blade 98 along the scraper bar 70 and debris is falling off of the scraper bar and into the bucket 20. Debris may be scraped such that it falls between the scraper bar and the top opening 21 of the bucket and may fall through the debris aperture 75 formed between the scraper bar 70 and the rim extension 72 of the bucket coupler 17.

(26) Referring to FIGS. 5 to 11, an exemplary implement scraper 17 has a rim extension 72 that is coupled to a top rim of a bucket. A left rim extension 74 extends circumferentially to the left from the bucket coupler 14 and magnetic coupler 77 and a right rim extension 76 extends to the right from the bucket coupler and magnetic coupler. A magnetic coupler 77 is configured on the top of the implement scraper, and has a pair of magnets 78 for retaining a scraper implement, or any other magnetic implement. The bucket coupler 14 has a latch 60 configured to detachably attach the implement scraper to the bucket. The latch handle 64 is configured to rotate about a latch pivot 62 to bring the latch lock end 65, and the latch lock 66 into engagement with the bucket, such as against the top rim of the bucket. The handle end 63 is rotated down to engage the latch lock with the bucket rim. The latch handle pivots within a latch slot 106 formed by the two opposing latch flanges extending down from the exterior flange. As shown in FIG. 6, the latch pivot 62, employs pivot extensions extending into latch pivot apertures 69 in the latch flanges 102. The scraper bar 70 is configured to extend across a top opening of a bucket and has a left end 71 and a right end 73 that are coupled proximal to the ends of the left rim extension and right rim extension, respectively. As shown in FIGS. 5 and 7 to 11, the scraper bar forms a debris aperture 75 between the scraper bar and the inside surface of the top extension 79 and the interior surface 27 of the wall 25 of the bucket. As shown in FIG. 11, the scraper blade extends an extension angle 23 around the outer circumference of the top rim 24 of the bucket. The extension angle shown is about 60 degrees.

(27) Referring now to FIGS. 12 and 13, an exemplary implement scraper 17 is configured on the top rim 24 of a bucket 20 with the rim slot 54 configured over the top rim of the bucket. In FIG. 12, the latch 60 is in an open configuration with the handle end 63 of the latch handle 64 rotated up and the latch lock end 65 and latch lock 66 rotated down away from the bucket. In FIG. 13, the latch handle 64 of the latch 60 is rotated about the latch pivot 62 to bring the latch lock end 65 and latch lock 66 into engagement with the top rim 24 of the bucket 20.

(28) As shown in FIG. 14, an exemplary implement scraper 17 is configured on the top rim 24 of a bucket 20 with the latch in a down and secured or latched configuration.

(29) As shown in FIG. 15, the implement scraper 17 is configured on the top rim 24 of a bucket 20, with the latch 60 in a down and secured or latched configuration. The rim slot 54 is a slot in the implement scraper that extends over the top rim of the bucket from the interior surface 27 to the exterior surface 29.

(30) Referring now to FIG. 16, the latch 60 is configured to rotate from an open position to a closed or locked position. The rim slot 54 is slightly wider than the top rim of the bucket and the width of the rim slot at the detent 56 is wider than the width of the rim slot above and below the detent. This detent allows the bucket wall to flex into the detent as the latch lock end of the latch handle 64 rotates up along the detent to provide a positive engagement past the detent to secure the bucket coupler 14 and implement scraper to the bucket. The detent slot width 59 is greater than the width of the rim slot 54 above and below the detent, as shown.

(31) Referring now to FIGS. 17 and 18, an exemplary latch 60 has a latch lock end 65 that has a radius of curvature 67 that may correspond substantially, within about 30% and preferably within about 20%, and more preferably within about 10%, of a radius of curvature of the outside surface of a bucket or the bucket rim, to enable the latch lock to slide along the outside surface of the bucket and past the latch detent in the interior flange, as shown in FIG. 16. As shown in FIG. 18 the latch pivot includes a pivot aperture in the latch handle 64. Also, the latch lock end 65 comprises a latch lock 66 and latch flange 68, configured to abut with a downward extension of the top rim of the bucket.

(32) It will be apparent to those skilled in the art that various modifications, combinations and variations can be made in the present invention without departing from the scope of the invention. Specific embodiments, features and elements described herein may be modified, and/or combined in any suitable manner. Thus, it is intended that the present invention cover the modifications, combinations and variations of this invention provided they come within the scope of the appended claims and their equivalents.
