The subject matter disclosed herein relates to archery bows and more particularly to risers for bows. Archery risers are the central portion of a bow that provide a means for attachment of other bow components such as limbs, grips, sights, etc. During a bow's draw cycle, the riser is placed under extreme stress which often produces riser deformation. Excessive deformation of the riser can hinder repeatability, accuracy, promote riser fatigue, decrease safety and negatively impact other parameters of the bow. An improved archery riser is therefore desirable. The discussion above is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed subject matter.
A riser for a bow is disclosed. The riser includes a top riser section that is joined to a middle riser section by a first and second step. The first and second steps strengthen the riser and permit the riser to be formed from less material while resisting undesirable deformation during use. An advantage that may be realized in the practice of some disclosed embodiments of the ability to produce a riser for a bow that uses less material than other risers while maintaining a riser that resists undesirable deformation.
In a first embodiment, a riser for a bow is provided. The riser comprises a top riser section joined to a middle riser section. The top riser section defines a first plane and the middle riser section defines a second plane. The first plane and the second plane are spaced from one another by a gap to provide an arrow shelf. The top riser section is joined to the middle riser section by both a first top step and a second top step. The first top step and the second top step join together at a first junction, separate from one another to form a cavity, then reunite at a second junction. The first junction is in the first plane and connects to the top riser section and the second junction is in the second plane and connects to the middle riser section.
In a second embodiment, a riser for a bow is provided. The riser comprises a top riser section joined to a bottom riser section by a middle riser section. The top riser section and the bottom riser section are aligned to define a first plane and the middle riser section defines a second plane. The first plane and the second plane are spaced from one another by a gap to provide an arrow shelf. The bottom riser section is joined to the middle riser section by a bottom step and the top riser section is joined to the middle riser section by both a first top step and a second top step. The first top step and the second top step join together at a first junction, separate from one another to form a cavity, then reunite at a second junction. The first junction is in the first plane and connects to the top riser section. The second junction being in the second plane and connects to the middle riser section.
In a third embodiment, a bow is provided. The bow comprises a riser comprising a top riser section joined to a bottom riser section by a middle riser section. The top riser section and the bottom riser section are aligned to define a first plane and the middle riser section defines a second plane. The first plane and the second plane are spaced from one another by a gap to provide an arrow shelf. The bottom riser section is joined to the middle riser section by a bottom step and the top riser section is joined to the middle riser section by both a first top step and a second top step. The first top step and the second top step join together at a first junction, separate from one another to form a cavity, then reunite at a second junction. The first junction is in the first plane and connects to the top riser section and the second junction is in the second plane and connects to the middle riser section. The bow further comprises a first bow limb removably attached to the top riser section and a second bow limb removably attached to the bottom riser section.
This brief description of the invention is intended only to provide a brief overview of subject matter disclosed herein according to one or more illustrative embodiments, and does not serve as a guide to interpreting the claims or to define or limit the scope of the invention, which is defined only by the appended claims. This brief description is provided to introduce an illustrative selection of concepts in a simplified form that are further described below in the detailed description. This brief description is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. The claimed subject matter is not limited to implementations that solve any or all disadvantages noted in the background.
So that the manner in which the features of the invention can be understood, a detailed description of the invention may be had by reference to certain embodiments, some of which are illustrated in the accompanying drawings. It is to be noted, however, that the drawings illustrate only certain embodiments of this invention and are therefore not to be considered limiting of its scope, for the scope of the invention encompasses other equally effective embodiments. The drawings are not necessarily to scale, emphasis generally being placed upon illustrating the features of certain embodiments of the invention. In the drawings, like numerals are used to indicate like parts throughout the various views. Thus, for further understanding of the invention, reference can be made to the following detailed description, read in connection with the drawings in which:

As shown in
In one embodiment, the riser is monolithic such that the top riser section, the bottom riser section and the middle riser section are formed as a single piece. The riser may be formed from a lightweight material, such as aluminum.
This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal language of the claims.
This application is a continuation of, and claims the benefit and priority of, U.S. patent application Ser. No. 15/163,291, filed May 24, 2016, which is a continuation of, and claims the benefit and priority of, U.S. patent application Ser. No. 14/492,396, filed on Sep. 22, 2014, which is a non-provisional of, and claims the benefit and priority of, U.S. Provisional Patent Application No. 61/880,303, filed on Sep. 20, 2013.
