| 20090036278 | Selectorized dumbbell having twin pin selector - A selectorized dumbbell has a handle that can be inserted into a gap between stacks of nested left and right weight plates that are provided in a plurality of nested weights. A selector determines how many left weight plates are coupled to the left end of the handle and how many right weight plates are coupled to the right end of the handle. A single left weight plate and a single right weight plate are interconnected together by an interconnection member of some type to form a single weight. The interconnection members of the different weights overlie one another and are provided with two arrays of a plurality of unique sets of holes and slots. A first connecting pin is inserted through the handle and through a selected set of holes and slots in the first array. A second connecting pin is inserted through the handle and through a selected set of holes and slots in the second array. The two pins together symmetrically couple the desired number of weights to the handle in a balanced fashion. | 02-05-2009 |
| 20090163335 | Selectorized dumbbell using commodity weights - This invention relates to a selectorized dumbbell having a handle that can be dropped down between nested left and right stacks of weight plates. The weight plates can comprise individual weights or a pair of weight plates, one from each stack, can be connected together to form a single weight. A selector is provided to allow the user to select a desired number of weight plates from each stack and couple such weight plates to the handle to provide an adjustable weight dumbbell. Each weight includes a weight frame having at least one carrier to which a commodity weight can be fastened. The dumbbell can be shipped by the manufacturer with empty weight frames to reduce shipping costs. When the dumbbell with empty weight frames reaches a destination, the dumbbell can be completed by securing commodity weights to the carriers on the respective weight frames. | 06-25-2009 |
| 20100074686 | Structure forming a breakwater and capable of ice free, year round operation - A structure for use in a body of water has at least one level that includes a boat lift, a narrow dock, or a larger entertainment area, or combinations of these items on multi-level structures (e.g. a boat lift on a first level and an entertainment area on a second level). The structure can be towed to or from a body of water independently of other structures. The structure includes a buoyancy system, e.g. at least one ballast tank or inflatable bladder, for allowing the structure to float in a buoyant state or to sink in a non-buoyant state into engagement with a bottom of the body of water. One or more structures such as these can be assembled to form an artificial breakwater by placing a wall or skirt on the windward side(s) thereof with each wall or skirt extending from below to significantly above the waterline. This forms a calmer area of water on the leeward side(s) thereof. In addition, an opposing wall or skirt can be placed on opposite sides of the structures to form a bounded chamber beneath the structure. A water recirculating device is used to pull up warmer water from near the bottom of the body of water and to discharge this warmer water into the bounded chamber and/or a water heating device is provided in the bounded chamber. This helps keep the structure sufficiently ice free to permit year round use if so desired even in northern climates. | 03-25-2010 |
| 20100261587 | SELECTORIZED DUMBBELL HAVING A SELECTOR COMPRISING A PIN HAVING FORK-SHAPED CONNECTING PRONG(S) - A selectorized dumbbell has a handle that can be inserted into a gap between stacks of nested left and right weight plates. A selector determines how many left weight plates are coupled to the left end of the handle and how many right weight plates are coupled to the right end of the handle. Each weight plate is held between a pair of flexible arms on a forked carrier. The arms allow the weight plates to deflect out of a normal, substantially upright, orientation if an impact shock is delivered to the dumbbell. The arms are restored to their normal orientation once the impact shock dissipates. Alternatively, the weight plates may comprise a metallic inner weight plate covered with an elastomer encasement and with an integral elastomer lug attaching the weight plates to at least one interconnecting member. The selector may comprise a connecting pin with at least one flexible shock absorbing prong. | 10-14-2010 |
| 20100323855 | SELECTORIZED DUMBBELL USING COMMODITY WEIGHTS - This invention relates to a selectorized dumbbell having a handle that can be dropped down between nested left and right stacks of weight plates. The weight plates can comprise individual weights or a pair of weight plates, one from each stack, can be connected together to form a single weight. A selector is provided to allow the user to select a desired number of weight plates from each stack and couple such weight plates to the handle to provide an adjustable weight dumbbell. Each weight includes a weight frame having at least one carrier to which a commodity weight can be fastened. The dumbbell can be shipped by the manufacturer with empty weight frames to reduce shipping costs. When the dumbbell with empty weight frames reaches a destination, the dumbbell can be completed by securing commodity weights to the carriers on the respective weight frames. | 12-23-2010 |
| 20110028285 | SELECTORIZED DUMBBELL HAVING OR CONVERTIBLE INTO KETTLEBELL CONFIGURATION - A selectorized dumbbell has nested stacks of left and right weight plates, a handle that can be disposed between the two stacks of weight plates, and a selector that couples selected numbers of the left and right weight plates to left and right planar ends of the handle. The handle has at least one loop type hand grip located above the ends of the handle and above the weight plates to allow the dumbbell to be used as a kettlebell. This loop type hand grip can be replaced with a bar type hand grip if the dumbbell is to be used like a standard dumbbell, or the handle can be provided in kettlebell or standard versions thereof. Alternatively, the loop type hand grip can be movably disposed on the handle for movement between operative and non-operative positions. | 02-03-2011 |
| 20110294629 | SELECTORIZED DUMBBELL HAVING SHOCK ABSORBING SYSTEM - A selectorized dumbbell has a handle that can be inserted into a gap between stacks of nested left and right weight plates. A selector determines how many left weight plates are coupled to the left end of the handle and how many right weight plates are coupled to the right end of the handle. Each weight plate is held between a pair of flexible arms on a forked carrier. The arms allow the weight plates to deflect out of a normal, substantially upright, orientation if an impact shock is delivered to the dumbbell. The arms are restored to their normal orientation once the impact shock dissipates. Alternatively, the weight plates may comprise a metallic inner weight plate covered with an elastomer encasement and with an integral elastomer lug attaching the weight plates to at least one interconnecting member. The selector may comprise a connecting pin with at least one flexible shock absorbing prong. | 12-01-2011 |
| 20110312475 | SELECTORIZED DUMBBELL WITH SELECTOR COMPRISING WEIGHT CONNECTING PINS CARRIED IN EACH END OF HANDLE - A selectorized dumbbell comprises a plurality of nested weights which have front and rear arrays of rails with the rails being vertically spaced from one another with a space beneath each rail. A handle is insertable into a gap between stacks of nested left and right weight plates. A selector comprises front and rear pin arrays in each end of the handle with the pins in these arrays being selectively movable in a horizontal direction into extended positions located in the spaces beneath the rails for coupling different weights to the handle. The pins in the arrays are movable into their extended positions by a single vertically movable member carried on a vertically rotatable shaft in the handle end or by a plurality of independently movable members in the handle end that are moved by a plurality of keys carried on a top side of the handle end. | 12-22-2011 |
