Description

Tool with a locking mechanism

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.

Disclosure of Invention

In view of the above, it is an object of the present invention to solve or at least reduce the above disadvantages. This object is at least partly achieved by a tool. The tool includes a handle defining a longitudinal axis along a length of the handle. The tool includes a first implement coupled to the handle. The first implement is adapted to treat soil in a first manner. The tool includes a second implement coupled to the first implement. 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.

According to one embodiment of the invention, the tool defines a transverse axis orthogonal to the longitudinal axis and passing through the coupling point of the second implement with the first implement. The second implement extends within about 15mm about the transverse axis.

According to one embodiment of the invention, the region extends to a distance of about 15mm on either side of the apex.

According to one embodiment of the invention, the second fixture is coupled to the first fixture at the apex.

According to one embodiment of the invention, the first implement is a backhoe and the second implement is a rake. The choice of first and second appliances may be from any suitable appliance that finds application in gardens.

According to one embodiment of the invention, the first implement has a first end that is disposed at a first impact angle when the handle is used at a first working angle. In addition, the second implement has a second end that is disposed at a second attack angle when the handle is used at the first working angle. The second impingement angle is equal to the first impingement angle.

According to one embodiment of the invention, the angular variation of the first and second impingement angles is less than 5 degrees.

According to one embodiment of the invention, the tool further comprises a third implement coupled to and extending angularly away from the second implement.

According to one embodiment of the invention, the third means extends orthogonally away from the second means.

According to one embodiment of the invention, the third means is orthogonal to the coupling of the second means to the first means.

Fig. 1 shows a garden tool 100. The present disclosure refers to rakes and uproots, however, the present disclosure may be readily applied to any garden tool 100, such as, but not limited to, shovels, forks, and the like. The tool 100 includes a handle 110 defining a longitudinal axis a-a' along a length of the handle 110. The tool 100 includes a first implement 120 coupled to a handle 110. The first implement 120 is adapted to dispose of soil in a first manner (i.e., hoe up the soil with a hoe 120). The tool 100 includes a second implement 130 coupled to the first implement 120. The second implement 130 is adapted to treat soil in a second manner different from the first manner (i.e., raking up the soil or weeds by the rake 130). As shown, the first implement 120 is a uprooting hoe 120 and the second implement 130 is a rake 130. Further, the uprooting hoe 120 of the present disclosure is shown with three teeth 121 (see fig. 2A, 2B, 3A, and 3B), however a practical implementation of uprooting hoe 120 may have any number of teeth or tines in any configuration or arrangement as used or known in the art. The choice of first and

second appliances

120, 130 may be any appliance that finds application in gardens.

The tool 100 has a first implement 120 defining an apex 140. The apex 140 is defined as a portion of the first utensil 120 disposed at a maximum orthogonal distance D from the longitudinal axis A-A'. The second fixture 130 is coupled to the first fixture 120 in the region of the apex 140 of the first fixture 120.

In addition, uprooting hoe 120 includes a first portion 122, a second portion 124, and a third portion 126. The first portion 122 has a straight shape and is attached to the handle 110. The second portion 124 has a curved shape and is attached between the first portion 122 and the third portion 126. Third portion 126 again has a straight shape and a first end 128 that engages the ground 202 during operation of the uprooting hoe 120, as shown in FIG. 2A. Likewise, the rake 130 has a second end 132 that engages the ground 202 during operation of the rake 130, as shown in fig. 2B.

In some embodiments, the second fixture 130 may be coupled to the first fixture 120 by welding, riveting, or any other suitable manufacturing technique used or known in the art. Furthermore, the second fixture 130 may be coupled to the first fixture 120 such that the second fixture 130 may be easily adjusted or moved within the area of the apex 140. This will allow to obtain different positions of the second appliance 130 with respect to the apex 140 of the first appliance 120 and thereby make the tool 100 more user friendly.

According to an embodiment of the invention, the tool 100 defines a transverse axis B-B 'orthogonal to the longitudinal axis a-a' and passing through the coupling point of the second implement 130 with the first implement 120. The second implement 130 extends within about 15mm about the transverse axis B-B'.

In a preferred embodiment, the region extends to a distance (X, Y) of 15mm on either side of apex 140 along longitudinal axis A-A'. The area may also have any other value of the distance (X, Y) depending on the application, in particular depending on the selection of the first 120 and second 130 appliances. In some embodiments, the value of distance X may be different than the value of distance Y, depending on the requirements of second fixture 130. Furthermore, the selection of the coupling point of the second fixture 130 may depend on a number of factors, such as the curvature of the second portion 124 of the first fixture 120, the shape of the second fixture 130 (i.e., the rake 130), and the like. Further, the second fixture 130 is coupled to the first fixture 120 at an apex 140.

As shown in fig. 1, the first implement 120 has a first end 128 that is disposed at a first attack angle β 1 when the handle 110 is used at a first working angle α, with combined reference to fig. 1, 2A, and 2B. In addition, the second implement 130 has a second end 132 that is disposed at a second attack angle β 2 when the handle 110 is used at the first working angle α. The second impingement angle β 2 is equal to the first impingement angle β 1. In some embodiments, the angular variation of the first and second impingement angles β 1, β 2 may be less than 5 degrees or any other value suitable for the application.

Fig. 2A and 2B show the tool 100 with the first implement 120 and the second implement 130, respectively, in the working position. As shown, the tool 100 may be used interchangeably with the first implement 120 and the second implement 130 by simply rotating the tool 100 about 180 degrees along the longitudinal axis A-A' of the handle 110. Furthermore, in this way, the tool 100 may have the same first and second impact angles β 1, β 2 for the first working angle α. In addition, the tool 100 will have a different working position of the handle 110, as shown in the present figures.

Fig. 3A and 3B show perspective views of a tool according to an embodiment of the present invention, wherein the first implement 120 and the second implement 130 are in the working position, respectively. As shown, the second implement 130 extends away from the first implement 120. This helps to position the second implement 130 almost opposite the first implement 120, and both the first and

second implements

120, 130 can then be used interchangeably by rotation of the tool 100 about the handle 110.

As shown in fig. 4A, 4B, and 4C, the tool 100 further includes a third implement 402, which is a brush. The third fixture 402 is coupled to the second fixture 130 and extends orthogonal to the second fixture 130. The third fixture 402 extends angularly away from the second fixture 130. As will be apparent to those having skill in the art, third fixture 402 may be any garden fixture used or known in the art.

In some embodiments, the third fixture 402 is orthogonal to the coupling of the second fixture 130 and the first fixture 120. This illustration of the third fixture 402 is merely preferred, and the present disclosure may be implemented with any coupling location, arrangement, type of the third fixture 402.
