DETAILED DESCRIPTION OF THE INVENTION
This disclosure relates to exercise devices comprising a weighted head and handle. In one embodiment, the exercise device may be essentially as shown in FIG. 1, FIG. 2, FIG. 3, and/or FIG. 4. In some embodiments, the exercise device may comprise: a weighted head (1); a handle (2) (in some embodiments referred to as “first tube”), in this embodiment comprising a first tube (12), and/or a receiver (10); and, an attachment device (3) for fixably attaching the weighted head and the tube, the attachment device (3) comprising a cap (19) and a second tube (6, 20); wherein: weighted head (1) optionally comprises: an inner (16) and an outer (17) surface enclosing an interior compartment (18) comprising a material (21) providing flexible weight to the weighted head (1); a first orifice (14) distal from the first tube (12); a second orifice (15) proximal to the first tube (12); attachment device (3) comprises a cap (19) and a connector (8) that may be received by a receiver (10) of the handle (2); the attachment device (3) contacts the outer surface of the weighted head by a cap (19); the cap (19) is fixably attached to the inner (16) and outer (17) surfaces of the weighted head (1); the attachment device (3) is fixably attached to the first tube (12); optionally first tube (12) and the second tube (6, 20) each comprise an orifice (7, 11) that align to one another upon attachment of attachment device (3) and handle (2); and, optionally further comprising a pin (13) protruding through each orifice (7, 11) to secure attachment device (3) and handle (2) to one another. In some embodiments, cap (19) may be fixably attached to the inner (16) and outer (17) surfaces by a bolt and nut combination (4, 9), a connector, and/or an adhesive. In some embodiments, material (21) may comprise sand, rubber and/or plastic. In some embodiments, weighted head (1) may comprise at least one orifice (14, 15) through which the first and/or second tubes (12, 6/20) enter and/or exit weighted head (1). In some embodiments, a first attachment device (3A) may be attached to weighted head (1) distal to the handle (2) and a second attachment device (3B) may be attached to weighted head (1) proximal to the handle (2) (e.g., as in FIG. 2). In some embodiments, the first tube (12) comprises one or more connectors (22) and weighted head (1) comprises one or more connectors (23) that interact with one another to secure weighted head (1) and handle (2) to one another (e.g., FIG. 3). In some embodiments, a system comprising multiple weighted heads (1) of different weights and a handle (2) such that the weighted heads (1) of different weights may be removably and interchangeably attached to handle (2).
An illustrative embodiment is shown in FIGS. 3A-H. FIGS. 3A and 3B provide side views of a completely assembled device comprising a weighted head (1) and a handle (2). In these embodiments, the weighted head includes a top cap apparatus (24) and a bottom connector apparatus (25), each of which are fixably attached (e.g., connected) thereto, and/or a second tube (26) traversing through weighted head (1) (e.g., as does 6/20 in FIG. 1). Top cap apparatus (24) and bottom connector apparatus (25) are typically positioned opposite one another with respect to the circumference of weighted head (1). For instance, top cap apparatus (24) may considered to be positioned at the “top” of weighted head (1) and the bottom connector apparatus (25) may be considered to be positioned at the “bottom” of weighted head (1). In some embodiments, second tube (26) may extend beyond the outside edge of weighted head (1), e.g., it may protrude from the weighted head (1) and through the bottom connector apparatus (25). Second tube (26) typically has a diameter greater than that of handle (2), such that handle (2) may be positioned within second tube (26) (e.g., in manufacture handle (2) may be inserted into second tube (26)). FIG. 3C provide top-down view of top cap apparatus (24). FIG. 3D provides bottom-up view of bottom connector apparatus (25). As shown in FIG. 3E, in these embodiments, top cap apparatus (24) typically includes tapped plate (27) adjoined to (e.g., welded to) second tube (26) (referred to in FIG. 3E as “outer tube”) through which handle (2) extends (i.e., in this embodiment, handle (2) is within second tube (26) (“outer tube”)). In such embodiments, the diameter of handle (2) is less than that of second tube (26). Retaining disc (28) may be affixed to (e.g., welded to) and extend outwardly from the top end of handle (2) and, in some embodiments may encircle the, or extend around the circumference of, handle (2). Tapped plate (27) provides through holes (29) through which screws or similar devices may be inserted and used to clamp weighted head (1) to second tube (26) (“outer tube”). In some embodiments, tapped plate (27) may encircle the, or extend around the circumference of, second tube (26). Rubber cap (30) is typically affixed onto this assembly to complete top cap apparatus (24), further secure the same, and provide a smooth exterior thereto. FIG. 3F-H illustrate a side views of the device, showing quick-release connector (31) positioned within handle (2) and distal to top cap (24) (i.e., the “bottom” of weighted head (1) where top cap apparatus is considered to be at the “top” of the device). Quick-release connector (31) is used to connect (e.g., secure) weighted head (1) handle (2) to one another. Quick-release connector (31) is typically positioned within handle (2) and comprises buttons that are depressed and released to connect to holes within second tube (26), thereby connecting (e.g., securing) weighted head (1) to handle (2). A suitable quick-release connector is a device designed to use spring force and a pin-like button to hold telescoping pieces of tubing together (e.g., handle (2) and second tube (26)). The quick-release connector is typically inserted into the smaller (e.g., that with a smaller diameter) of the two tubes. The smaller diameter tube (e.g., handle (2)) is then inserted into the larger diameter tube (e.g., second tube (26)) until the connector button (which reversibly protrudes through a hole through the wall of the smaller diameter tube) pops into a hole of the larger diameter tube (e.g., second tube (26)) to reversibly secure the tubes to one another. Suitable quick-release connectors are widely available to those of ordinary skill in the art (e.g., the Zinc-Plated Steel Quick-Release Connector available from McMaster-Carr, such as part number #94282A370). As shown in FIG. 3H, the bottom connector apparatus (25) may include tapped plate (32) adjoined to second tube (26) (referred to in FIG. 3E as “outer tube”) through which handle (2) extends (i.e., as for the top cap piece (24), in this embodiment, handle (2) is within second tube (26) (“outer tube”)). Tapped plate (32) provides through holes (33) through which screws or similar devices may be inserted and used to clamp weighted head (1) to second tube (26) (“outer tube”). This section of the second tube (26) (“outer tube”) also includes holes (34) positioned to receive the connector buttons of the quick-release connector (31). As described above, this arrangement provides for weighted head (1) to be reversibly connected to handle (2). In some embodiments, second tube (26) may have a diameter less than that of handle (2) (first tube), and second tube in positioned within handle (2). In some embodiments such as this, or others, the quick-release connector may be positioned within either the handle (2) or the second tube (26). The exercise device could also comprise a single tube providing the functions of both handle (2) and second tube (26). Other embodiments of this device may be designed by varying the parts described herein as would be understood by those of ordinary skill in the art.
Another illustrative embodiment is shown in FIG. 4. As illustrated in FIG. 4A, in one embodiment, the exercise device can include a handle attachment assembly body (35) extending through a weighted head (48, in some embodiments at least partially filled with fill material 47). Handle attachment assembly body (35) includes screw threads at each end (i.e., two opposite threaded ends). In the illustrated embodiment, the screw threads at each end extend from within the interior to the exterior of weighted head (48) (e.g., crossing the support material forming the surface of weighted head (48)). At each such end, a first set of one or more washers (preferably one) and one or more nuts (preferably one) are affixed to the interior screw threads and a second set of one or more washers (preferably one) and one or more nuts (preferably one) are affixed to the exterior screw threads, with the support material forming the surface of weighted head (48) positioned between the two sets. Tightening the nuts against the washers secures the same against the surface of that support material, therefore forming a seal (e.g., enclosing the fill material (47) within the interior of weighted head (48)). FIG. 4A illustrates two sets of these components at each end of handle attachment assembly body (35) as arrangements 45 and 46. FIG. 4B provides a view of an assembled weighted head including washer/nut arrangements 45 and 46 positioned at either end of weighted head (48). In some embodiments, the handle attachment assembly body (35A) can be prepared as a molded and/or welded piece comprising a support surface (e.g., a shelf or shoulder; internal welded flange (49)) providing the same function as that provided by the interior washer/nut assembly and can include screw threads (50) protruding beyond the main body thereof (see, e.g., FIG. 4C (but typically not including the holes shown therein). In such embodiments, the washer/nut arrangement positioned on the opposite surface (e.g., the exterior) of weighted head (48) can be tightened onto that support surface (e.g., 49), thereby providing a sealing function to maintain (i.e., seal) the fill (47) within weighted head (48), such that it does not substantially leak (or leak) from the interior of weighted head upon use. In some embodiments, a sealing and/or or adhesive material, such as but not limited to a sealant (e.g., a silicone rubber such as Dow Corning® RTV Sealant), may be applied between any of these components (e.g., the surface (e.g., the exterior) of weighted head (48) and any other component) in order to, e.g., further maintain fill (47) within weighted head (48). In some embodiments, such a sealant and/or adhesive is present between the exterior washer (e.g., 38 and 43 in FIG. 4A) and surface (e.g., the exterior) of weighted head (48). In such illustrative embodiments, a handle assembly (51) is typically positioned within the handle attachment assembly body (35), (e.g., traversing through the center of weighted head (48)) (e.g., a handle assembly comprised of a single tube and providing the functions of both handle (2) and second tube (26), as described above) and provide for reversible attachment to weighted head (48) thereto. As shown in FIG. 4D, the tube forming the handle typically includes corresponding holes (52) on each side through which an attachment device such as, but not limited to, a pin (53; e.g., a cotter pin, lock pin) affixed thereto and securing weighted head (48) and handle (51) to another. The washer/nut assembly (45) at the top of weighted head (48) is typically covered by a cap 54 (e.g., a flexible cap such as a rubber cap) (although an inflexible cap may also be suitable) that can be affixed to the handle using an adhesive such as, but not limited to, an epoxy. Cap (54) may also be adjoined with other materials (e.g., additional washers and/or the like) providing additional support to that junction between the washer/nut assembly (45) and the handle assembly (51) (FIG. 4E). In some embodiments, this illustrative exercise device, and variations thereof, may be assembled by inserting the handle assembly (53) through weighted head (48) such that holes (52) protrude from weighted head (48) such that an attachment device (e.g., pin 53) may be reversibly affixed thereto through the holes to reversibly attach weighted head (48) and handle assembly (53) (e.g., FIG. 4F). This disclosure also provides methods of manufacturing this illustrative exercise device by, for instance, preparing weighted head comprising opposite holes and inserting handle attachment assembly body (35) into the same and tightening the one or more washer/nut assemblies (e.g. 45, 46) thereto, inserting handle assembly through handle attachment assembly body (35), and inserting attachment device (e.g., pin 53) through holes in handle attachment assembly body (35) to secure weighted head and handle attachment assembly body to one another. In some embodiments, interior and exterior nuts (37, 40, 41, 44) are not included, and instead interior and exterior washers (38, 39, 42, 43) are threaded washers, thereby providing a similar structural support to the device as the combination of nuts and washers. In some embodiments, the above-mentioned sealing and/or or adhesive material are positioned between the is positioned (e.g., applied) between the exterior washer (e.g., 38 and 43 in FIG. 4A) and surface (e.g., the exterior) of weighted head (48), although in some embodiments it could also be positioned (e.g., applied) between an interior washer and the interior surface of weighted head (48). Other embodiments of these illustrative devices and methods are also contemplated herein as will be understood by those of ordinary skill in the art.
