Description
Technical Field
The present disclosure relates to a garden tool. More particularly, the present disclosure relates to a garden tool that provides the benefits of different types of tool implements integrated in a user-friendly manner.
Background
Garden tools have found widespread use in many outdoor applications. Root-digging hoes (grubbers) and rakes are versatile garden tools used in gardens and the like. Hoe for uprooting soil is commonly used in outdoor applications. The rake includes a rake portion having a plurality of straight tines to rake soil or weed pieces thereafter. However, there are concerns about functional and structural constraints, particularly due to the need to maintain and store different tools for such applications.
In the past, efforts have been made to integrally couple different tool combinations with a handle in order to obtain the benefits of a uprooting hoe or rake with a single tool. Such efforts have failed to address some of the major problems associated with stress on the hoe, rake or handle of the tool. Furthermore, these problems pose an obstacle to the best working angle of the tool and the user-friendly implementation.
An example of a garden tool is provided in U.S. patent No. 2,225,108 (hereinafter the' 108 reference). The' 108 reference provides a combination implement that includes a coarse operating element (e.g., a rake tooth or a cultivator hoe) on one side for breaking the ground first and a fine operating implement or rake tip on the other side for breaking up coarser pieces of soil. In addition, the grinding rollers cooperate to reduce the argillization into a powder or fine covering. However, due to the angle limitations, the' 108 reference does not optimize the structural efficiency of the coarse and fine operating elements of the combined tool. This limitation may also have an effect on the volume carrying capacity or vandalism capacity of the combination.
Accordingly, there is a need for an improved garden tool that is adaptable to a variety of tasks while having the advantages of different types of tool implements into which the garden tool is integrated.

The second implement is adapted to treat soil in a second manner different from the first manner. The tool is characterized in that: the first utensil defines an apex. The apex is defined as a portion of the first implement disposed at a maximum orthogonal distance from the longitudinal axis. The second implement is coupled to the first implement in the region of the apex of the first implement. Thus, the present disclosure provides a simple, efficient and user-friendly tool that allows for the use of different types of implements that are cleverly coupled to the tool.
According to one embodiment of the invention, the second implement extends away from the first implement. This helps to position the second implement almost opposite the first implement, and both the first and second implements can then be used interchangeably by rotation of the tool about the handle.
