Abstract
A bucket attachment for an excavator including a single bucket having a base, a right side wall, a left side wall, a right guide wing, a left guide wing, and a rear wall. A rotatable crossbar is continuously disposed from a first aperture disposed in the right guide wing to a second aperture disposed in the left guide wing. A pair of inverted V-shaped mounting cleats is disposed on an exterior surface of the rear wall adjacent a top edge. A pivotable frame is attached to the crossbar, and a return spring is disposed around the crossbar and attached to the frame.
Claims
1. A bucket attachment for an excavator comprising: a single bucket having a base, a right side wall, a left side wall, a right guide wing, a left guide wing, and a rear wall having an exterior surface, a top edge, a right edge disposed between the right side wall and the right guide wing and a left edge disposed between the left side wall and the left guide wing, each of the right guide wing and the left guide wing having a bottom rear corner; a rotatable crossbar continuously disposed from a first aperture disposed in the right guide wing proximal the bottom rear corner to a second aperture disposed in the left guide wing proximal the bottom rear corner, wherein one of a pair of bushings is attached to each of a right surface of the crossbar and a left surface of the crossbar; a pair of inverted V-shaped mounting cleats comprising a right mounting cleat and a left mounting cleat, each of the right mounting cleat and the left mounting cleat having a first edge and a second edge, wherein the first edge of each of the right mounting cleat and the left mounting cleat is disposed on the exterior surface of the rear wall adjacent to the top edge and proximal the right edge and the left edge, respectively; wherein the pair of mounting cleats is configured to releasably attach to an excavator blade of an excavator; a pivotable frame attached to the crossbar, wherein the frame is configured to releasably attach to the excavator blade of the excavator; a return spring disposed around the crossbar and attached to the frame, wherein the return spring is configured to maintain a positioning of the frame; a pair of elongated downwardly disposed hooks comprising a right hook and a left hook, each of the right hook and the left hook having a front edge, a rear edge, an upper surface, and a lower surface, wherein the upper surface of the right hook proximal the rear edge is attached to the crossbar proximal the right surface, and the upper surface of the left hook proximal the rear edge is attached to the crossbar proximal the left surface; a pair of L-shaped brackets comprising a right bracket and a left bracket, wherein each of the right bracket and the left bracket is attached to the rear edge of each of the right hook and the left hook, respectively; a pair of supports comprising a front support and a rear support, wherein each of the front support and the rear support is continuously disposed from the upper surface of the right hook to the upper surface of the left hook; wherein the front support and the pair of hooks are perpendicularly disposed; wherein the rear support and the pair of hooks are perpendicularly disposed; and a plurality of crossbeams, each of the plurality of crossbeams continuously disposed from the rear support to the front support, wherein each of the plurality of crossbeams and the front support are perpendicularly disposed.

DETAILED DESCRIPTION OF THE DRAWINGS
(7) With reference now to the drawings, and in particular
(8) Referring to
(9) A rotatable crossbar 44 is continuously disposed from a first aperture 46 disposed in the right guide wing 28 proximal the bottom rear corner 42 to a second aperture 48 disposed in the left guide wing 30 proximal the bottom rear corner 42. One of a pair of bushings 50 is attached to each of a right surface 52 of the crossbar 44 and a left surface 54 of the crossbar 44.
(10) The present bucket attachment for an excavator 10 also includes a pair of inverted V-shaped mounting cleats 56 and a pivotable frame 58 attached to the crossbar 44. The pair of mounting cleats 56 includes a right mounting cleat 60 and a left mounting cleat 62. Each of the right mounting cleat 60 and the left mounting cleat 62 has a first edge 64 and a second edge 66. The first edge 64 of each of the right mounting cleat 60 and the left mounting cleat 62 is disposed on the exterior surface 34 of the rear wall 32 adjacent to the top edge 36 and proximal the right edge 38 and the left edge 40, respectively. The pivotable frame 58 is attached to the crossbar 44. A return spring 68 is disposed around the crossbar 44 and attached to the frame 58. As best shown in
(11) The frame 58 optionally includes a pair of elongated downwardly disposed hooks 74, a pair of L-shaped brackets 76, a pair of supports 78, and a plurality of crossbeams 80. The pair of hooks 74 includes a right hook 82 and a left hook 84. Each of the right hook 82 and the left hook 84 has a front edge 86, a rear edge 88, an upper surface 90, and a lower surface 92. The upper surface 90 of the right hook 82 proximal the rear edge 88 is attached to the crossbar 44 proximal the right surface 52, and the upper surface 90 of the left hook 84 proximal the rear edge 88 is attached to the crossbar 44 proximal the left surface 54. The pair of L-shaped brackets 76 includes a right bracket 94 and a left bracket 96. Each of the right bracket 94 and the left bracket 96 is attached to the rear edge 88 of each of the right hook 82 and the left hook 84, respectively. The pair of supports 78 includes a front support 98 and a rear support 100. Each of the front support 98 and the rear support 100 is continuously disposed from the upper surface 90 of the right hook 82 to the upper surface 90 of the left hook 84. Both the front support 98 and the rear support 100 are perpendicularly disposed with the pair of hooks 74. Each of the plurality of crossbeams 80 is continuously disposed from the rear support 100 to the front support 98, and each of the plurality of crossbeams 80 is perpendicularly disposed with the front support 98. The plurality of crossbeams 80 is optionally three.
