DETAILED DESCRIPTION OF THE INVENTION

[0017] While this invention is susceptible to embodiment in many different forms, there is shown in the drawings, and will herein be described in detail, specific embodiments with the understanding that the present disclosure of such embodiments is to be considered as an example of the principles and not intended to limit the invention to the specific embodiments shown and described. In the description below, like reference numerals are used to describe the same, similar, or corresponding parts in the several views of the drawings. This detailed description defines the meaning of the terms used herein and specifically describes embodiments in order for those skilled in the art to practice the invention.

Definitions

[0018] The terms “about” and “essentially” mean ±10 percent.

[0019] The terms “a” or “an”, as used herein, are defined as one or as more than one. The term “plurality”, as used herein, is defined as two or as more than two. The term “another”, as used herein, is defined as at least a second or more. The terms “including” and/or “having”, as used herein, are defined as comprising (i.e., open language). The term “coupled”, as used herein, is defined as connected, although not necessarily directly, and not necessarily mechanically.

[0020] The term “comprising” is not intended to limit inventions to only claiming the present invention with such comprising language. Any invention using the term comprising could be separated into one or more claims using “consisting” or “consisting of” claim language and is so intended.

[0021] Reference throughout this document to “one embodiment”, “certain embodiments”, “an embodiment”, or similar terms means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of such phrases in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments without limitation.

[0022] The term “or”, as used herein, is to be interpreted as an inclusive or meaning any one or any combination. Therefore, “A, B, or C” means any of the following: “A; B; C; A and B; A and C; B and C; A, B, and C”. An exception to this definition will occur only when a combination of elements, functions, steps, or acts are in some way inherently mutually exclusive.

[0023] The drawings featured in the figures are for the purpose of illustrating certain convenient embodiments of the present invention and are not to be considered as limitation thereto. The term “means” preceding a present participle of an operation indicates a desired function for which there is one or more embodiments, i.e., one or more methods, devices, or apparatuses for achieving the desired function and that one skilled in the art could select from these or their equivalent in view of the disclosure herein, and use of the term “means” is not intended to be limiting.

[0024] As used herein, the term “dual hook” refers to a device that has both a grab hook and a sling hook, wherein the grab hook and the sling hook are aligned and connected linearly through their centers with the hook cradles facing the same way or facing 180 degrees apart aligned and lying flat on the same plane. In one embodiment, they are joined head to toe, and in another embodiment, they are joined toe to toe. The hook portion is an open cradle, bowl, or groove as shown in the figures. As can be seen in the figures, each of the hooks has a wide side and a narrow side. In making the dual hook, each hook is laid down on the wide side and as described, connected head to toe as shown in the figures. A chain connector is attached to a top of the grab hook and the sling hook is attached to a bottom of the grab hook. The two hooks are aligned linearly along the access as shown in the figures. Chain connectors are well known in the art.

[0025] As used herein, the term “a grab hook” refers to a grab type hook that is a type of lifting hook designed to grab an object with which it is being used. They are designed primarily for overhead lifting applications. Grab hooks have an open design that have an open cradle or groove forming the hook shape. The grab hook is positioned on top with a chain connector.

[0026] As used herein, the term “a sling hook” refers to a type of lifting hook that is characterized by the use of a retainer latch positioned at the top of the bowl. The retainer latch consists of a long and solid metal spring loaded bar. The latch is opened by pressing the latch inward. The latch however, cannot be opened further by pulling on it (i.e., it offers only a one-way action). The sling hook is positioned below the grab hook.

[0027] As used herein, the term “connected linearly” refers to each of the hooks connected head to toe linearly aligning each hook's center line as seen in the figures. This is accomplished by laying both hooks down on the wide side. The figures and their corresponding descriptions contain more specific details.

[0028] As used herein, the term “facing the same way or facing 180 degrees apart aligned” refers to the opening of the cradle of each hook either facing the same way or facing 180 degrees apart aligned, as shown in the figures.

Drawings

[0029] Now referring to the drawings, FIG. 1 is a perspective view of a dual hook device 1. The dual hook device 1 has a grab hook 2 and a sling hook 3 joined together at sling hook head 5 and grab hook toe 4. It is noted that in this embodiment, they are both laying on the wide side 6 on a flat surface and the cradles 7a and 7b face 180 degrees apart aligned. The center line 10 of each hook is aligned and connected linearly. On top of the grab hook 2, is a chain connection device 9 for attaching the dual hook device 1 to a chain or other desired object. The top of the sling hook head 5 is attached to the toe of the grab hook 2 by use of either a fixed or rotary connector.

[0030] FIG. 2 is a perspective view depicting the grab hook 2 and the sling hook 3 attached from sling hook head 11 to grab hook toe 12. In this view, the openings 13a and 13b are facing the same way. In both cases, they are attached linearly and lay flat.

[0031] Those skilled in the art to which the present invention pertains may make modifications resulting in other embodiments employing principles of the present invention without departing from its spirit or characteristics, particularly upon considering the foregoing teachings. Accordingly, the described embodiments are to be considered in all respects only as illustrative, and not restrictive, and the scope of the present invention is, therefore, indicated by the appended claims rather than by the foregoing description or drawings. Consequently, while the present invention has been described with reference to particular embodiments, modifications of structure, sequence, materials, and the like apparent to those skilled in the art still fall within the scope of the invention as claimed by the applicant.
