1. Field of the Invention
The invention relates to an improved rake assembly. More particularly, the present invention pertains to a rake for gathering and removing debris from a lawn, field, garden or other surface.
2. Brief Description of the Prior Art
Rakes are well known. Further, use of rakes is well known to assist in gathering and/or consolidating cut grass, fallen leaves, weeds, paper, plastic trash and/or other materials (collectively referred to herein as “debris”) into piles. Once consolidated into piles, such debris is frequently transferred to either a central disposal location, or desirable mulch or trash depositories.
Conventional rakes have remained relatively unchanged for many years. Conventional rakes typically include a lateral head (usually, approximately 1 foot wide) having a series of rigid metallic teeth or tines, widely spaced, and extending from said lateral head (usually about 3 inches). Further, said conventional rakes typically have an extended handle for pulling said rake over the ground or other surface in order to contact and gather debris. By way of illustration, but not limitation, a conventional rake can be passed over a lawn of fallen leaves to gather and form said leaves into a pile for transfer and removal/disposal.
One particular type of conventional rake is commonly referred to as a “grass rake”. A conventional grass rake typically includes a lateral head (usually about 1½ feet wide) having a series of fanned flexible teeth members, closely spaced, with curved and downwardly-facing tips. Further, said conventional grass rakes typically have an extended handle for pulling said rakes over the ground or other surface in order to contact and collect debris. By way of illustration, but not limitation, a conventional grass rake can be passed over a lawn of recently mowed grass to gather and form said cut grass into pile(s) for transfer and removal/disposal.
In one variation, a grass rake has a head that can be selectively repositioned; the rake can be utilized in typical fashion by pulling to rake over grass, and then converted to a “push rake” by turning the head over so that the teeth extend upwardly. Said overturned rake further includes a pair of side walls extending a short distance above and along a fan-shaped head of the rake. The over-turned curved teeth can be used to push the grass forward of the teeth into a pile; any grass that travels over said teeth are confined on the upper fan by the short walls. Said head can then tipped or overturned in order to form grass into a pile.
Another variation involves a separate bagging device that is utilized with a conventional rake or broom for transferring a pile of debris into said bagging device for subsequent removal. Said bagging device is separate from the rake assembly.
All prior art rakes are utilized to first rake debris into piles; thereafter, said piled debris must be further transferred into a bagger, cart or other collector for removal and/or disposal. As such, a user is required to bend down to lawn level in order to transfer a pile of debris for removal. Such bending is not possible by some disabled users, and can also cause stress, strain and pain to healthy users.
In view of the foregoing, it is an object of the present invention to provide a rake assembly that does not require an operator to bend or stoop to collect and remove debris from a lawn or other surface.
It is another object of the present invention to provide a rake assembly that integrally collects debris from a lawn or other surface for removal to a desired depository.
It is another object to provide a rake assembly with an integral debris collector that is relatively inexpensive to manufacture, and that is reliable and durable in use.
The present invention comprises a rake assembly for gathering and removing debris from a lawn or other surface. In a preferred embodiment, the rake assembly of the present invention includes a substantially planar base plate having a forward end, a rearward end, an upper surface, and a plurality of teeth or tines extending outward from the forward end of said plate. As said plate is moved in a direction that is substantially parallel to a lawn or other surface, the horizontal teeth direct debris onto the upper surface of said plate.
A handle having a substantially U-shaped yoke is pivotally attached to said plate, typically near the sides of the forward end of the plate, and extends upwardly from said plate. Said U-shaped yolk defines an opening for receiving debris that is raked or otherwise directed onto said plate. Said handle further comprises an elongated shaft extending from the yoke for maneuvering and manipulating the rake along the lawn or other surface being raked.
A flexible collection bag having a front end, a rear end, and a bottom portion is positioned horizontally on the upper surface of the plate. In the preferred embodiment, said bottom portion has a width extending substantially to the sides of the plate and a length extending from the forward end to the rearward end of said plate. Further, in the preferred embodiment, said bag has side portions extending upwardly from the lower portion and a generally rectangular top portion enclosing the side portions. The rear end of said collection bag is enclosed, and the front end of the bag is secured around the opening formed by said plate and said yoke of the handle, for collecting the debris that is received through such opening.
During use, the angle of the extended opening of said bag varies depending upon the angle of the handle and whether the rake is pushed or pulled along the lawn or other surface being raked. After said collection bag has been filled with debris, the rake assembly of the present invention can be conveniently carried or dragged to a desired depository, where said debris can be emptied from the bag into a lawn bag, trash bin or other receptacle.
The foregoing summary, as well as the following detailed description of the preferred embodiments, is better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, the drawings show certain preferred embodiments. It is understood, however, that the invention is not limited to the specific methods and devices disclosed. Further, dimensions, materials and part names are provided for illustration purposes only and not limitation.

Teeth 24 are preferably formed integrally with plate 20; alternatively, a set of teeth 24 can be formed as a separate component and attached to forward end 21 of plate 20. In a preferred embodiment, said teeth 24 are preferably narrow, closely spaced, resiliently flexible and have tips thereof angled or curved upwardly relative to surface 22 of plate 20, in order to facilitate raking movement by said teeth 24 without snagging or gouging into a lawn, ground or other surface being raked. Although the amount of said curvature can vary, it is to be observed that said tips of said teeth 24 can be angled or curved about ½ inch relative to plate 20.
In a preferred embodiment, handle member 30 comprises a substantially cylindrical and elongate shaft member 31. Grip section 32 is disposed at one (upper) end of shaft member 31 for easy and convenient gripping of said handle member by a user. A threaded connection 33 can be disposed at the opposite (lower) end of elongate shaft member 31 from grip section 32.
Substantially U-shaped yoke member 35 can be attached to shaft member 31, such as with a threaded connection 34 that can mate with threaded connection 33 of said handle member assembly 30. Aligned apertures 37 are formed at ends 36 of yoke member 35.
In a preferred embodiment, yoke member 35 is pivotally attached to said plate member 20. Although different attachment means can be employed, said yoke member 35 can be pivotally attached to plate 20, in the embodiment depicted in
Apertures 37 at the ends of yoke member 35 are aligned and mate with apertures 25 in base plate 20. Lateral axel member 38 extends between said aligned apertures in order to pivotally attach yoke member 35 to plate member 20. Yoke member 35 cooperates with lateral axel 38 and upper surface 22 of base plate 20 to form an opening for receiving debris that is raked onto said plate member 20.
Yoke member 35 can be suitably formed of tubular material having ends 36 thereof formed with journals, or flattened with circular apertures 37 for pivotal connection to plate 20. In a preferred embodiment, elongate shaft member 31 is also suitably formed of tubular material.
