Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

One or more embodiments of the present invention are related to an apparatus for modifying weight distribution of a device such as a sporting gear like a golf club, a racket (e.g., for tennis, racquetball, squash, table tennis, etc.) or tools.

2. Description of Related Art

Conventional mechanisms for modifying weight distribution of sporting equipment such as a tennis racket to customize the racket with a desired weight balance (head-heavy, head-light, or balanced weight distribution) are well known and have been in use for a number of years. Regrettably, most are comprised of many constituent parts or pieces that are complicated to manufacture and install.

Accordingly, in light of the current state of the art and the drawbacks to balancing schemes and methods thereof mentioned above, a need exists for an apparatus that would enable modifying a weight distribution of a device to achieve a desired balancing of the weight of the device that is simple to manufacture and install.

BRIEF SUMMARY OF THE INVENTION

A non-limiting, exemplary aspect of an embodiment of the present invention provides an apparatus, comprising:

a single piece weight member that is generally configured commensurate with an existing, single piece component of a device to facilitate replacing the existing, single piece component of the device with the single piece weight member to modify a weight distribution of the device to a desired weight balance, with the single piece weight member having a greater weight than a component weight of the existing, single piece component of the device.

DETAILED DESCRIPTION OF THE INVENTION

The detailed description set forth below in connection with the appended drawings is intended as a description of presently preferred embodiments of the invention and is not intended to represent the only forms in which the present invention may be constructed and or utilized.

In the description given below and or the corresponding set of drawing figures, when it is necessary to distinguish the various members, elements, sections/portions, components, parts, or any other aspects (functional or otherwise) or features or concepts or operations of a device(s) or method(s) from each other, the description and or the corresponding drawing figures may follow reference numbers with a small alphabet character such as (for example) “single piece weight member 102a, 102b, and etc.” If the description is common to all of the various members, elements, sections/portions, components, parts, or any other aspects (functional or otherwise) or features or concepts or operations of a device(s) or method(s) such as (for example) to all single piece weight member 102a, 102b, etc., then they may simply be referred to with reference number only and with no alphabet character such as (for example) “single piece weight member 102.”

Throughout the disclosure, references to tennis racket, tennis racket handle or grip are meant as illustrative, are for convenience of example, and for discussion purposes only. That is, the present invention should not be limited to the use of tennis rackets but may also be used (without much modifications, if any) for other equipment such as golf clubs or other sporting or non-sporting equipments that may require modification or change in weight distribution for a desired weight balance.

One or more embodiments of the present invention provide an apparatus that when installed, modifies a weight distribution of a device to achieve a desired balancing of a weight of the device that is simple to manufacture and very easy to install.

One or more embodiments of the present invention provide an apparatus that is comprised of a single piece weight member that is generally configured commensurate with an existing, single piece component of a device to facilitate replacing the existing, single piece component of the device with the single piece weight member to modify a weight distribution of the device to a desired weight balance, with the single piece weight member having a greater weight than a component weight of the existing, single piece component of the device.

FIGS. 1A-1 to 1E are a non-limiting, exemplary illustration of an embodiment of an apparatus that replaces an existing component of a device and that when installed, changes a weight distribution of a device in accordance with one or more embodiments of the present invention. As illustrated, a single piece weight member 102 is provided that is generally configured commensurate with an existing, single piece component 104 of a device 106. That is, at the very least, single piece weight member 102 has an engagement infrastructure that is generally configured or shaped corresponding with an exiting engagement infrastructure of the existing single piece component 104, which would facilitate simple replacement of the existing, single piece component 104 of device 106 with single piece weight member 102 without any modifications to device 106. In other words, single piece weight member 102 has a generally complementary engagement infrastructure in relation to a part 114a of the device 106 that accommodates existing, single piece component 104, which would allow single piece weight member 102 to engage with device 106.

As further illustrated and indicated by arrows 108 and 154, a users may simply remove or detach existing, single piece component 104 in well known manner, and attach (also in a well known manner) in its place single piece weight member 102 as indicated. by arrow 110, resulting in modified weight balanced device 106 (shown in FIG. 1A-2). Since single piece weight member 102. has a greater weight than a component weight of existing, single piece component 104 of device 106, the replacement with single piece weight member 102 would modify a weight distribution of device 106 to a desired weight balance. Accordingly, the desired weight balance of device 106 may be achieved with a very simple, quick and easy to install single piece weight member 102.

Single piece weight member 102 may have an exoskeleton structure that encases or encapsulates weight material 212. The overall weight of single piece, integrally molded weight member 102 may vary in accordance with a weight of the material 212 (best shown in FIGS. 2D) integrated within, while single piece, integrally molded weight member 102 maintains configuration adapted to replace the existing, single piece component 104 of device 106. In general, the weight material 212 (FIGS. 2D) of single piece, integrally molded weight member 102 may comprise of various alloys such as metal alloys with varying weights. This means that a multiplicity of single piece, integrally molded weight members 102 with each having different weights may be manufactured while maintaining the general configuration or shape of members 102 still commensurate with the existing, single piece component 104. The weight of weight material 212 (FIGS. 2D) encased within single piece, integrally molded weight members 102 may for example, be varied by set increments, which would vary the overall weight of single piece, integrally molded weight members 102 in set increments. Accordingly, use of different weighted single piece, integrally molded weight members 102 may incrementally vary a weight distribution of device 106 and hence, which would enable users to precisely reach a desired weight balance in set increments, For example, a user may install a first member 102 with a first weight and if resulting change in the weight distribution is not the desired weight balance, the user may simply replace the first member 102 with the first weight with another member 102 with a second weight that may be incrementally higher or lower in weight compared with the first member 102.

It should be noted that although many well known methods for manufacturing single piece, integrally molded weight members 102 exist, one non-limiting exemplary known method may include using a plastic molded metal (or metal alloy) weight using existing molding processes. A plastic or other suitable types of molded weight material would form the exoskeleton structure within which the weight material is integrally molded and held to form single piece, integrally molded weight member 102. It should further be noted that single piece weight member 102 itself may comprise of weight material (e.g., various metals or metal alloys with varying weight without the exoskeleton structure). That is, the weight material itself may be molded into single piece weight member 102.

As exemplarily shown in FIG. 1A-1, in the non-limiting exemplary instance illustrated, the device 106 is a tennis racket 106a with a handle or grip portion 112a, and existing, single piece component 104 is the illustrated end cap 104a of the handle 112a. End cap 104a may be easily detached or disengaged (“popped” or “snapped”) out and removed, exposing a butt cap 114a and interior portion or hollow cavity 116a of handle 112a of the tennis racket 106a. Butt cap 114a includes engagement infrastructure (detailed below) that allows end cap 104a to securely “snap” or engage with butt cap 114a of handle 112a of racket 106a.

In this non-limiting, exemplary instance, single piece weight member 102a includes a base 118a configured commensurate with a base 120a of end cap 104a, which may in fact, include the same exact design and logo or brand of base 120a of end cap 104a visible to users, In this non-limiting, exemplary instance base 118a is octagonal shape with eight-(8) edges 136a, generally configured commensurate with that of end cap 104a that also has an octagonal shape with eight-(8) edges 138a.

Protruded from an interior facing surface 122a of base 118a is an engagement infrastructure 124a of single piece weight member 102a that is generally configured commensurate an engagement infrastructure 152 of the end cap 104a, enabling single piece weight member 102a to engage and securely connect with butt cap 114a. More specifically, in this non-limiting, exemplary instance, engagement infrastructure 124a (which is shaped like the engagement infrastructures 152 of end cap 114) is comprised of a groove 126a formed between interior facing surface 122a of base 118a and flanges 128a, with edge 130a of butt cap 114a engaging groove 126a of single piece weight member 102a.

As further illustrated, protruded from a surface 132a of flanges 128a is an optional, substantially cylindrical protuberance 134a that may form a “compartment” for weight material encapsulated (or molded) within member 102a, which when installed, is inserted within interior portion or hollow cavity 116a of handle 112a of racket 106a. As an optional, non--limiting example, cylindrical protuberance 134a may be provided with two cavities 140a and 142a, which may be used to integrally encase molded weighted material. It should be noted that protuberance 134a need not be cylindrical or have any cavities and further, may be configured in any desired shape independent of even the shape of end cap 114a so long as it may be inserted within interior portion or hollow cavity 116a of handle 112a, and does not interfere with the engagement of single piece weight member 102a with butt cap 114a.

FIGS. 2A to 2D are a non-limiting, exemplary illustration of an embodiment of an apparatus that replaces an existing component of a device and that when installed, changes a weight distribution of the device in accordance with one or more embodiments of the present invention. Single piece weight member 102b illustrated in FIGS. 2A to 2D includes similar corresponding or equivalent components, interconnections, functional, operational, and or cooperative relationships as single piece weight member 102a that is shown in FIGS. 1A-1 to 1E, and described above. Therefore, for the sake of brevity, clarity, convenience, and to avoid duplication, the general description of FIGS. 2A to 2D will not repeat every corresponding or equivalent component, interconnections, functional, operational, and or cooperative relationships that has already been described above in relation to single piece weight member 102a that is shown in FIGS. 1A-1 to 1E.

As best illustrated in FIGS. 2A and 2B, in this non-limiting, exemplary instance, single piece weight member 102b includes a base 118b configured commensurate with a base 120a of end cap 104a, which may in fact, include the same general design and logo or brand of base 120a of end cap 104a visible to users. In this non-limiting, exemplary instance base 118b is octagonal shape with eight-(8) edges 136b, generally configured commensurate with that of end cap 104a that also has an octagonal shape with eight-(8) edges 138a.

As illustrated in FIGS. 2A to 2D, protruded from an interior facing surface 122b of base 118b is an engagement infrastructure 124a of single piece weight member 102b that is generally configured commensurate an engagement infrastructure 152 of the end cap 104a, enabling single piece weight member 102b to engage and securely connect with butt cap 114a. Further included are two prongs 208 that protrude from the secondary surface 210 that may be inserted into blind-holes 156 of butt cap 114a, with single piece weight member 102b engaging butt cap 114a (as shown in FIG. 2B).
