Description

FIELD OF THE INVENTION

The present invention relates generally to ratcheting tools and, more particularly, to a hand tool including a pivoting ratchet-end and a pivoting operational-end.

BACKGROUND OF THE INVENTION

Conventional ratchets include a tool-engaging or fastener-engaging head portion that is attached to a handle so that a user may position of the head portion relative to a work piece or fastener. One (1) problem with conventional ratchets is that the location where the ratchet head is needed is narrow or otherwise hard to reach.

As a solution, ratchets having ratchet heads that pivot with respect to the wrench's handle for adjusting fasteners in hard to reach locations were developed. However, since only the ratchet head disposed at an end of the ratchet handle is adjustable according to a particular need, the operational angle of the grip end of the ratchet wrench is not adjustable, therefore, the applicability of the conventional pivot-head ratchet wrench is limited.

Accordingly, there is a need for a ratcheting device that addresses the problems in the art.

SUMMARY OF THE INVENTION

The inventor has recognized the aforementioned inherent problems and lack in the art and observed that there is a need for a ratcheting device that affords a user the ability to adjust not only the position of a ratchet head but also an operational end or grip end of a ratchet handle.

Further, those skilled in the art will recognize that other styles and configurations can be incorporated into the teachings of the present disclosure, and that the example configurations shown and described herein are for the purpose of clarity and disclosure and not by way of limitation.

As used herein, the singular terms “a”, “an”, and “the” do not denote a limitation of quantity, but rather denote the presence of at least one (1), as well as a plurality of, the referenced items, unless the context clearly indicates otherwise.

As used herein, the terms “first”, “second”, “third”, etc. are used as labels to describe various elements, features, and/or components, and are not intended to impose ordinal, positional, or hierarchical requirements on the referenced items, unless other indicated. For example, such terms may be used to distinguish one (1) element from another element.

As used herein, relative terms such as “front”, “rear”, “left”, “right”, “top”, “bottom”, “below”, “above”, “upper”, “lower”, “horizontal”, or “vertical” are used to describe a relationship of one (1) element, feature and/or region to another element, feature and/or region as illustrated in the figures.

Referring to FIGS. 1-4, disclosing a split handle ratchet tool (herein described as the “device”) 10, where like reference numerals represent similar or like parts. Generally, the device 10 includes a ratchet-type tool including a selectively angled two-part handle member (e.g., upper handle member 40 and lower handle member 46) while mechanically maintaining parallelism between a ratchet head 20 and opposing ring grip 60. The device 10 can be scaled to provide various sized drives 22, such as one-quarter inch (¼ in.), three-eighths inch (⅜ in.), one half inch (½ in.), etc. Furthermore the device 10 can be introduced having various overall lengths; however, those skilled in the art will appreciate that a relatively small model of the device 10 (e.g., approximately six inches (6 in.) in length) would be especially useful in tight places, such as under a vehicle dashboard and the like.

Referring to FIGS. 1 and 2, the device 10 includes a ratchet head 20, an upper handle member 40, a lower handle member 46, and a ring grip 60. The handle members 40, 46 each include a rigid linear connecting member being attached at one (1) end to the ratchet head 20 and at an opposing end to the ring grip 60 using respective pivot pins 50.

The handle members 40, 46 are arranged in a parallel (e.g., over-under) manner. The upper handle member 40 is attached to the ring grip 60 via a first upper handle hinge 42a made up of interconnected elements that are integrally-molded into the upper handle member 40 and the ring grip 60. The first upper handle hinge 42a is secured by a pivot pin 50 that passes through a pivot pin aperture 51 of the first upper handle hinge 42a and is retained via a friction fit.

In a similar manner, the opposing end of the upper handle member 40 is attached to the ratchet head 20 via a second upper handle hinge 42b made up of interconnected elements that are integrally-molded into the upper handle member 40 and ratchet head 20 and is secured with pivot pin 50 and pivot pin aperture 51.

The subjacent (e.g., under) lower handle member 46 is attached to the ring grip 60 via a first lower handle hinge 48a secured using a pivot pin 50 and to the ratchet head 20 via a second lower handle hinge 48b secured using a pivot pin 50.

Referring to FIG. 2, the pivot pins 50 are rotatingly attached to the handle members 40, 46, thereby allowing a relative angle to occur between the handle members 40, 46, and the ratchet head 20 and ring grip 60. The device 10 is depicted in FIG. 2 having an upwardly angled configuration (shown in solid lines), as well as being positioned horizontally (as depicted by a first alternate position 21a and shown in broken lines), and angled downwardly (as depicted here by a second alternate position 21b and shown in broken lines). Due to the parallel nature of the handle members 40, 46 and respective pivot pins 50 within the ratchet head 20 and ring grip 60, the ratchet head 20 and ring grip 60 are retained within respective parallel plains regardless of the relative angles of the handle members 40, 46.

Referring to FIG. 3, the ratchet head 20 includes a ratcheting mechanism. Ratcheting mechanisms of this type are well known in the art. As one (1) example, the ratcheting mechanism can be similar to the ratcheting mechanism of the ratchet wrench disclosed in U.S. Pat. No. 6,543,316 filed on Mar. 14, 2001, the disclosure of which is herein incorporated by reference in its entirety. However, those skilled in the art will recognize that other ratcheting mechanisms having more, less, or different components or various different designs can be utilized without deviating from the teachings of the present disclosure, and as such should not be interpreted as a limiting factor.

In one (1) example construction, the device 10 includes internal components that are well known in the art and provide conventional selectable bi-directional operation. For example, the device 10 includes major components such as, but not limited to: a gear-type ratchet drive 22, a directional switch 23, a gear 26, and a cover plate 28. In use, the directional external switch 23 is positioned within and passes through a switch aperture 24. The switch 23 is manually rotated to position an engaged internal gear 26 against the drive 22 to deliver one-way clockwise or counterclockwise torque in a known manner.

Referring to FIG. 4, a circular embodiment of the ring grip 60 of the device 10 is depicted here being particularly sized for use upon a user's finger 100 to enhance control and gripping of the device 10 to avoid dropping the device 10 during use. However, those skilled in the art will appreciate that the ring grip 60 of the device 10 can be provided having different shapes and corresponding ring grip apertures 62 being suitable to encompass a plurality of fingers 100 without deviating from the teachings of the present disclosure, and as such should not be interpreted as a limiting factor.

As depicted in FIG. 4, while retaining the device 10 upon a user's finger 100, another finger 100 can be used to manipulate a relative angle of the handle members 40, 46 to position and align a socket 110 being mounted to the ratchet head 20 to a fastener 105 as needed.

Those skilled in the art will recognize that other styles and configurations of the disclosed device 10 can be easily incorporated into the teachings of the present disclosure, and only particular configurations have been shown and described for purposes of clarity and disclosure and not by way of limitation of scope.

The disclosed embodiments of the device 10 can be utilized by the common user in a simple and effortless manner with little or no training. After initial purchase or acquisition of the device 10, it would be installed as illustrated in FIGS. 1, 2, and 4.

One (1) embodiment of the disclosed method for utilizing the device 10 includes the following steps: 1). procuring a model of the device 10 having a desired size drive 22 and overall length; 2). installing a desired drive socket 10, or similar tool element which fits the drive 22; 3). placing the ring grip 60 over a user's finger 100; 4). using remaining fingers 100 to manipulate the handle members 40, 46, as desired, to obtain a desired position of the ratchet head 20; 5). engaging a fastener 105 or other rotating item with the device 10 and socket 110; 6). rotating the ring grip 60 to rotate the ratchet head 20 and deliver a torque to the fastener 105; and 7). repeating the previous steps for additional fasteners 105.

Accordingly, a user of the disclosed device 10 benefits from improved gripping and access to difficult to reach fasteners 105.

The foregoing descriptions of specific embodiments have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit to the precise forms disclosed and many modifications and variations are possible in light of the above teachings.
