ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an accessory for a loader and more particularly to a wing which is arranged to be mounted on the end of a bucket of a front end loader.
BACKGROUND
It is a known practice for work vehicles such as a front end loader to be used in place of a scraper for moving loose materials, for example snow in colder climates. These vehicles however are normally intended for scooping earth and the like and are not well suited for collecting loose materials similarly to a scraper as required in snow removal for example.
U.S. Pat. No. 5,129,169 to Aubichon provides an attachment for use on vehicles equipped with a bucket. The attachment includes a pair of side members which are arranged to extend generally forward from the respective ends of the bucket and a frame which is coupled therebetween for mounting the side members on the bucket to increase the volumetric capacity of the bucket. A pair of mounting hooks must be welded onto the bucket in order to support the attachment thereon. The task of welding however is expensive and not readily available to persons having only conventional tools. Furthermore, the frame extends between respective inner faces of the side members and is required to extend at least partially in front of the opening of the bucket in order to adequately support the side members. In this arrangement, the frame obstructs the accumulation of material between the side members, while further limiting the spacing therebetween such that the attachments cannot be adapted to different size buckets.
SUMMARY
According to the present invention there is provided an accessory for a loader bucket having an open front side and a back side, the accessory comprising:
a wing;
hook means mounted on the wing for engaging over a front edge of the bucket adjacent the open front side; and
fastener means mounted on the wing for fastening the wing to the back side of the bucket.
The wing increases the overall plowing width of the loader bucket which is useful for reducing the number of passes required when using a loader to collect material from a given area. The use of hook means and fastener means allows the wing to be mounted on the bucket of a loader with minimal or no modifications to the bucket, requiring only the use of conventional tools to secure a single bolt onto the bucket.
The wing may include a frame extending longitudinally from a front end mounting the hook means thereon to a rear end mounting the fastener means thereon and a panel extending transversely to the frame so as to extend laterally outward from the bucket when the frame is mounted thereon.
The hook means may comprise a pair of hooks mounted one spaced above the other, each hook being arranged to extend over the front edge of the bucket adjacent one end of the bucket.
The hooks are preferably mounted on a front side of the wing such that the wing is arranged to extend laterally outward from the front side of the bucket.
The fastener means may comprise an aperture in the wing arranged to align with an aperture in the bucket for receiving a fastener therethrough.
Preferably the aperture in the wing is spaced rearward from a front face of the wing.
At least one strut member is preferably mounted between the frame and the panel.
There may be provided a pair of the strut members mounted spaced one above the other between the frame and the panel.
The strut members are preferably mounted at an inner end on the frame of the wing to extend laterally outward at a forward incline to an outer end mounted on a free end of the panel.
The panel may extend laterally outward at a forward incline from the front end of the frame.
The panel may further be inclined rearwardly from a bottom end to a top end thereof in relation to the frame.
There may be provided an end plate mounted on the free end of the panel to extend forwardly therefrom, the end plate being oriented to lie substantially parallel to the frame.
