This invention is directed toward a manually operable gardening tool which can be used either as a weeder or as a rake whereby the user can weed and/or rake without having to use separate tools for each operation.
Methods and apparatus for expanding the usefulness of hand tools by affixing alternate types of tool heads to a single tool handle have been the subject of much inventive effort over the years. The basic approach of providing multipurpose tools flows naturally from the need to utilize a number of different hand tools serially in time to accomplish a gardening task. In gardening or landscaping uses, a first tool type might be used to precondition the soil, and a second tool type might be needed to further prepare particular areas, or to complete processes which were missed on the initial passes. The use of a long-handled hoe followed by the use of a long-handled rake to collect the debris produced by the hoe gives an example of where iterative uses of alternate tool types are commonly needed. Hence, multipurpose tools of wide varieties abound; as do devices where a number of different tool heads may be affixed to a single, specially adapted handle.
Common to hand operated gardening tools is the use of a elongated handle. Secured to one end of the handle is an implement for use in cultivating, weeding or grooming of the soil. The tools are typically arranged to complete a specific task and the tool is thereafter exchanged for the tool required to complete the next task. Attempts have been made to combine tools or construct tools with interchangeable implements, however, such attempts typically employ the use of bayonet mounts or clamping devices helping little in the way of efficiency.
For instance, U.S. Pat. Nos. 2,268,066 and 2,314,685 teach a rake attached to an elongated handle via a spring mechanism. The device further includes a weed cutter attached to the handle in a manner that allows the rake to be stood upright without assistance. The weed cutter is formed of metal having an elongated body which partly surrounds the handle to provide support and a “spoon” shaped and sharpened cutter end.
U.S. Pat. No. 3,987,609 teaches a manually operable garden tool which combines the functions of a rake and a weeder. The tool employs an elongated handle with a generally flat section coplanar with the handle. A plurality of spring tines essentially coplanar with the section are provided. Each tine is secured at one end to the curved periphery and extends outward at right angles whereby the handle, tines and section define a rake. An elongated weed blade extends in the same direction as the handle and is secured at one end of the handle. The other end of the blade lies in a plane parallel to the tines.
U.S. Pat. No. 3,921,725 teaches a combination hoe and fork device. The device includes a handle fixed to a blade by means of a tang. The tang curves upwardly from the blade and then generally at a right angle to the blade and is attached by a suitable socket in the usual manner. The fork is of standard construction having an outwardly extending stem which can be attached to the tang of the hoe with U-bolts or hose clamps.
U.S. Pat. No. 4,236,742 teaches a retractable rake for use as a courtesy rake by a golfer at a sand trap, or for light raking chores in general. The rake has a plurality of projecting tines which diverge outwardly when they are in their extended position. When the rake is not in use, the tines are retractable into the shank of the rake so the rake is compact and may be stored and carried within a golf bag.
U.S. Pat. No. 4,843,667 teaches a combination broom, rake, and pruning knife for use as a household, yard, garden, or industrial tool. The combination tool includes an elongated handle. The handle has at one end a removable broom assembly that is held in place by a post which fits in a socket and a lock screw. A rake tine support chamber is mounted parallel to the broom support chamber. The rake tine support chamber provides mounting and support for a plurality of retractable rake tines, which may be provided with hooked ends. The retractable rake tines are arranged in two groups, one on each side of the centerline of the tool, each having a similar number of tines. Each group of rake tines is attached by a pivot pin to a sliding linkage. When the tines are extended, they are supported by the flared end of the rake tine support chamber and the broom head serves as a backing for the rake tines limiting their deflection. The rake tines may be retracted into the rake retraction chamber by pulling the sliding hand grip. The opposite end of the handle is provided with a removable knife which may be used by hand or attached to the handle for pruning purposes.
U.S. Pat. No. 5,185,992 teaches a tool expanding assembly which provides the means for rapidly coupling any one of a number of different tool heads to a preexisting mother tool. The tool expanding assembly includes a pair of cylinder-like portions which are fabricated from metal and rigidly connected together. In use, one of the cylinder-like portions is fitted over the handle of the mother tool and fasteners are inserted to secure the assembly. The second cylinder-like portion is constructed to include a square J-shaped bayonet connector slot, which is adapted to receive corresponding male bayonet connector elements used to terminate the ends of various tool heads.
U.S. Pat. No. 5,411,101 teaches a combination cultivator and edging tool including a handle and a head attached to one end of the handle. The head includes a transverse support member and a row of long cultivator tines, each tapering from a point of connection to the support member toward a tip. The tines extend in a common plane of extension disposed generally perpendicular to the handle and the transverse support member. The head further includes a blade having a support edge and a sharpened edge opposite the support edge. The blade is disposed in the same plane as the handle and the transverse support member. In use, the handle is disposed at an angle to the ground for cultivating. The handle is alternatively disposed vertically with respect to the ground for edging.
U.S. Pat. No. 5,743,340 teaches a device for pulling weeds, plants, small trees and the like which includes an elongate handle portion terminating in a first end, with a leveraging head member attached to the first end. This leveraging head member has a first side bearing a weed clamp having at least one pivoting jaw adapted to close proximate to a clamping surface, and a second side opposite the first side bearing a lever arm for mechanical advantage.
Hand tools utilizing bayonet type mounts have the disadvantage of requiring the user to perform the desired task using two individual tools, wherein each of the tools has to be handled separately in order to do the job. Often changing tools with a bayonet mount takes longer than exchanging complete tools.
The prior art also fails to teach a combined tool that allows the operator to cultivate and change tools to groom without bending over to change tools. Standing upright lessens the strain on an individual's back, and combining tools increases efficiency.
Thus, what is lacking in the art is a combination tool that includes a scuffler hoe and rake for gardening and landscaping. The combination tool should include a loop type scuffler blade and a retractably mounted rake head. The loop shaped scuffler blade should allow weeding and cultivating operations to be performed while pushing or pulling on the elongated handle for increased efficiency. The combination tool should merely require the handle to be rotated to change tools, allowing cut vegetation to be raked or cultivated soil to be groomed without bending over to change tools. The rake head should be retractable and/or collapsible to facilitate weeding operations to be performed in tight areas.
This invention pertains to hand operated gardening and landscaping tools for use in cultivating soil and/or removing inferior or unwanted plants from a selected area. More particularly, the present invention relates to a combination scuffling hoe and rake assembly. The combination tool allows an operator to cut unwanted weeds below the ground surface and thereafter groom the weeded area without having to use separate tools to complete the task.
The tool employs an elongated handle with a scuffler hoe portion and rake portion attached at a distal end thereof. The scuffler hoe portion comprises a generally elongated metal blade formed into a U-shaped loop and sharpened on both edges. The ends of the metal blade are each secured at the distal end of the handle, via a ferrule, at an obtuse angle with respect to the longitudinal centerline of the handle.
In one embodiment, the rake assembly is slidably mounted on the elongated handle and includes a locking means to secure the rake assembly in a retracted or an extended position. The rake assembly includes a plurality of tines. Each tine is fixed in a diverging manner generally coplanar to the flat portion of the loop blade and includes a formed tip for drawing together leaves or cut grass as well as smoothing loose soil.
In an alternative embodiment, the rake assembly includes a plurality of pivotally mounted tines which may be folded inwardly to narrow the profile of the device. In this embodiment the tines are pivotally secured to a sliding member by a pivot pin in an overlapping fashion at one end. The center portion of each tine extends through a guide member secured to the distal end of the handle whereby moving the sliding member toward the distal end of the handle causes the tines to extend and diverge outward. The sliding member includes means to lock the sliding member in an extended or retracted position.
The construction of the device allows the rake to be locked into the retracted position while cultivating for easy access to confined areas. The tool can then be turned over and the rake assembly extended so the tool can be used as a rake to gather cut weeds and/or smooth the cultivated surface.
Thus, an objective of the instant invention is to provide a novel combination tool that is versatile and efficient in use, and lends itself to a variety of gardening and landscaping activities.
Another objective of the instant invention is to provide a combination hand tool having a scuffler hoe blade and a slidingly retractable rake assembly.
Yet another objective of the instant invention is to provide a combination hand tool which provides a scuffler hoe and a rake assembly having a set of folding and retracting tines.
