DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
FIGS. 1-9 show a weight 100 constructed according to the principles of the present invention. The weight 100 is preferably made of cast iron, covered with vinyl, and sized and configured to weigh 1.25 pounds and define a maximum linearly measured dimension (or length) of 6.25 inches. One alternative embodiment of the present invention is preferably scaled down to weigh 0.5 kilograms and define a maximum linearly measured dimension (or length) of 6 inches. Unless otherwise specified, all measurements are plus or minus 0.25 inches. In a broader sense, the weight 100 may be described as a hand-held weight that weighs between 1 and 1.5 pounds and defines a maximum linearly measured dimension of between 5 and 7 inches.
The weight 100 may be described in terms of a first segment 110, a second segment 120, and a juncture 130 of integral interconnection between the first segment 110 and the second segment 120. The girth or circumference of the weight 100 is relatively greater at the juncture 130, and each segment 110 and 120 decreases in girth as a function of distance from the juncture 130. The maximum height of the depicted weight 100 (measured parallel to line Q in FIG. 8) is 2.5 inches. The maximum width of the depicted weight 100 (depicted in FIGS. 4-7 and measured perpendicular to the length and the height) is 1.5 inches.
The weight 100 may be described as symmetrical relative to a plane of symmetry extending through the first segment and the second segment and containing the length of the weight 100 (parallel to the drawing sheet of FIG. 8 and perpendicular to the drawing sheet with reference to FIGS. 4 and 5). Also, the first segment 110 may be described as symmetrical in a manner that accommodate a similar fit in the person's hand when the weight is rotated 180 degrees about its length (see FIGS. 10x and 10y).
Over a longitudinally measured distance of 4.5 inches, the girth of the first segment 110 decreases from approximately 1.25 inches proximate the juncture 130 to approximately 0.25 inches proximate its distal end. The first segment 110 may be described as a cone-shaped member that tapers from the end proximate the juncture 130 to an opposite distal end. The first segment is sized and configured for grasping comfortably in a person's hand and thus, may also be described as a handle segment.
Over a distance of 1.6 inches, the girth of the second segment 120 decreases from approximately 1.25 inches proximate the juncture 130 to approximately 0.5 inches proximate its distal end. The second segment 120 may also be described as a tab or flange configured and arranged to alternatively (a) comfortably overlie a person's forefinger when the handle segment 110 is comfortably grasped in a first orientation by all four fingers (see FIGS. 10a-10b); (b) comfortably overlie outwardly facing skin extending between a person's thumb and forefinger when the handle segment 110 is comfortably grasped in a second orientation by at least the three fingers furthest from the person's thumb (see FIG. 10c); and (c) fit comfortably between a person's forefinger and middle finger when the handle segment 110 is comfortably grasped by the three fingers furthest from the thumb (see FIG. 10g).
One-half of the mass of the weight 100 occupies less than one-third of the length of the weight 100, including all of the juncture 130 (and all of the second segment 120 on the depicted embodiment 100), and the other one-half of the mass of the weight 100 occupies more than two-thirds of the length of the weight 100, including most of the first segment 110. More specifically, FIG. 8 shows a line Q that represents a plane passing orthogonally through the first segment 110 and dividing the weight 100 into half in terms of mass. X indicates the overall length of the weight 100 (6.25 inches); Y indicates the fractional length (4.5 inches) of the one-half of the mass of the weight 110 disposed on one side of Q; and Z indicates the fractional length (1.75 inches) of the one-half of the mass of the weight 110 disposed on an opposite side of Q. R is a longitudinal axis associated with the first member 110, and P is a point of intersection between R and Q.
The juncture 130 integrally joins the first segment 110 and the second segment 120 in a manner that defines both an acute interior angle or corner between the first segment 110 and the second segment 120, and an obtuse exterior angle or corner between the first segment 110 and the second segment 120. The interior angle (designated as G in FIG. 9) is preferably between 35 and 50 degrees, and is depicted as 40 degrees. The exterior angle (designated as H in FIG. 9) is preferably between 310 and 325 degrees, and is depicted as 320 degrees. A first fillet rounds the interior corner, and a second fillet rounds the exterior corner, and all surfaces of the weight 100 are curved. The juncture 130 has a girth of 2 inches, as measured along a line L bisecting the interior angle, and a maximum girth of 2.25 inches, as measured perpendicular to the line bisecting the interior angle (and as far “inboard” as possible while remaining clear of the first segment 110 and the second segment 120).
FIGS. 10a-10g show various ways in which the weight 100 may be comfortably held in a person's hand. For description purposes, the weight 100 in each of the FIGS. 10a-10g is further designated with a letter (e.g. “100a”) to distinguish between the manners in which the weight 100 is positioned relative to the person's hand. Also, the person's hand H is described in terms of a thumb T, a forefinger F, and three other fingers, including a middle finger M, a ring finger, and a little finger.
In FIGS. 10a-10b, the weight 100a is held comfortably in the person's hand H with the thumb T and all four fingers wrapped around the first segment 110 (like a closed fist), and with the second segment 120 comfortably overlying the person's forefinger F.
As compared to the weight 100a in FIGS. 10a-10b, the weight 100c in FIG. 10c is essentially rotated 180 degrees about the longitudinal axis of the first segment 110 relative to the person's hand H. In this regard, the weight 100d is held comfortably in the person's hand H with the thumb T and all four fingers wrapped around the first segment 110 (like a closed fist), and with the second segment 120 comfortably overlying outwardly facing skin extending between the person's thumb T and forefinger F.
As compared to the weight 100c in FIG. 10c, the handle segment 110 of the weight 100d in FIG. 10d is tilted to a less perpendicular orientation relative to the person's thumb T and fingers. In this regard, the weight 100d is held comfortably in the person's hand H with the thumb T and the forefinger F wrapped around the juncture 130, the other three fingers wrapped around the first segment 110 (more like a golf grip), and the second segment 120 comfortably overlying outwardly facing skin extending between the person's thumb T and forefinger F.
As compared to the weight 100d in FIG. 10d, the weight 100e in FIG. 10e is flipped to essentially reverse the positions of the first segment 110 and the second segment 120. In this regard, the weight 100e is held comfortably in the person's hand H with the thumb T and the forefinger F wrapped around the juncture 130, at least the middle finger M wrapped around the first segment 120, and the first segment 110 comfortably overlying outwardly facing skin extending between the person's thumb T and forefinger F.
The weight 100f in FIG. 10f occupies the same orientation relative to the person's hand H as the weight 100a in FIGS. 10a-10b. However, the person's thumb T is moved from a closed first position to a position comfortably overlying the curved end of the weight 100f (i.e. the exterior corner defined by the juncture 130).
As compared to the weight 100a in FIGS. 10a-10b, the weight 100g in FIG. 10g is moved down “one finger width” relative to the person's hand H. In this regard, the weight 100g is held comfortably in the person's hand H with the thumb T and the forefinger F wrapped around the juncture 130, the other three fingers wrapped around the first segment 110 (like a closed fist), and with the second segment 120 comfortably overlying the person's middle finger M (and comfortably underlying the person's forefinger F).
To arrive at yet another hand-hold on the weight 100, the ends of the weight 100a in FIGS. 10a-10b are essentially reversed in the person's hand H. In this arrangement (not shown), the weight 100 is held comfortably in the person's hand H with the thumb T and all four fingers wrapped around the first segment 110 (like a closed fist), and with the second segment 120 comfortably underlying the person's little finger.
FIGS. 11-13 show a second weight 200 constructed according to the principles of the present invention. The front and back views of the second weight 200 are identical to those of the first weight 100, so FIGS. 3 and 9 may also be described as front and back views, respectively, of the weight 200, and FIG. 13 may be described as a reoriented front view of the weights 100 and 200. Moreover, the second weight 200 is identical to the first weight 100 except as noted below, and may be held as shown in and described with reference to FIGS. 10a-10g. As compared to their counterparts on the first weight 100, the first segment 210 and the second segment 220 on the second weight 220 have respective cross-sections that are relatively more circular and relatively less elliptical. As a result, the juncture 230 is not quite the same as the juncture 130, and the second weight 200 weighs less than the first weight 100 when built to the same overall scale. For ease of reference, the respective distal ends 211 and 222 of the segments 210 and 220 are labeled in FIGS. 11-12.
FIGS. 13-14 show a third weight 300 constructed according to the principles of the present invention. The third weight 300 is identical to the first weight 100 except as noted below. The first segment 110′ is identical to the first segment 110 on the first weight 100, except that its distal end has been modified to receive and retain a first end 351 of a hand strap 350. The juncture 130′ is identical to the juncture 130 on the first weight 100, except that its outside corner has been modified to receive and retain an opposite, second end 353 of a hand strap 350. The ends of the hand strap 350 are secured by conventional means, including physical fasteners, complementary snap fit features, sonic welding, over-molding, and/or adhesives. The hand strap 350 is preferably made of plastic or rubber and includes an intermediate portion 355 that extends between the ends 351 and 353 and cooperates with the first segment 110′ to define a slot 359 sized and configured to receive a person's hand.
In one respect, the weights 100 and 200 may be described as j-shaped, and thus, the subject invention may be described and/or claimed in terms of a j-shaped exercise weight. In this respect, the term “j-shaped” is intended to mean shaped like many versions of the letter “j” without any separate tittle included. Representative examples include the lower case “j” in Microsoft Word fonts Comic Sans MS, Kristen ITC, and Segoe Print; the upper case “J” in Microsoft Word fonts Century Gothic, Euphemia, Maiandra Gb, Matisse ITC, Mistral, and Segoe Print; the weight 100 oriented as shown in FIGS. 3 and 8; and any and all variations that fall between these examples.
As shown in FIG. 9, which is a back view (and thus, a mirror image of the front view) of the weight 100, inwardly facing co-planar edges of the first segment 110, the second segment 120, and a respective rounded corner edge or curve 114 cooperate to form a first j-shaped edge designated as 141 (which appears as a reverse “j-shape” in FIG. 9 but nonetheless appears as a standard “j-shape” in FIGS. 3 and 8). Similarly, outwardly facing co-planar edges of the first segment 110, the second segment 120, and a respective rounded corner edge or curve 124 cooperate to form a relatively larger, second j-shaped edge designated as 142 (which appears as a reverse “j-shape” in FIG. 9 but nonetheless appears as a standard “j-shape” in FIGS. 3 and 8).
In another respect, the weights 100 and 200 may be described as substantially j-shaped, and thus, the subject invention may be described and/or claimed in terms of a substantially j-shaped exercise weight. In this respect, the term “substantially j-shaped” is intended to mean a shape that is recognizable in certain contexts as a stylized version of an upper case or lower case letter “j” (without any separate tittle included). For example, when informed that the weight 100 oriented as shown in FIG. 3 or 8 is representative of a letter of the English alphabet, most literate English speaking adults are likely to identify the image as the letter “j”. Or, when the weight 100 oriented as shown in FIG. 3 or 8 is substituted for the letter “j” in a common English word or name that appears within the context of a phrase or title, a majority of literate English speaking adults are likely recognize the image as a stylized version of the letter “j”. Examples include when the weight 100 oriented as shown in FIG. 3 or 8 is substituted for the letter “J” in the phrase “Join the Army” or for the letter “j” in the phrase “here comes the judge”.
In another respect, the weights 100 and 200 may be described as check-mark-shaped, and thus, the subject invention may be described and/or claimed in terms of a check-mark-shaped exercise weight. In this respect, the term “check-mark-shaped” is intended to mean shaped like many variations of a check mark that is used to check off an item on a list. Representative samples include the check mark symbol in the Microsoft font Wingdings; the weight 200 oriented as shown in FIG. 13; and any and all variations that fall between these examples.
In another respect, the weights 100 and 200 may be described as asymmetrically v-shaped, and thus, the subject invention may be described and/or claimed in terms of an asymmetrically v-shaped exercise weight. In this respect, the term “asymmetrically v-shaped” is intended to mean shaped like a modified letter “v” where one leg of the “v” is significantly longer than the other. Representative examples, include combining one leg of a lower case “v” with an opposite side leg of an upper case “V” in Microsoft Word font Comic Sans MS or Segoe Print; the weight 200 oriented as shown in FIG. 13 (where the first segment or leg is at least twice as long as the second segment); and any and all variations that fall between these examples.
The present invention has been described with reference to preferred embodiments and methods of using the preferred embodiments with the understanding that this disclosure will enable persons skilled in the art to derive various modifications, improvements, and/or applications that nonetheless embody the essence of the subject invention. In view of the foregoing, the scope of the present invention is to be limited only to the extent of the following claims.
