The present invention generally relates to the field of exercise equipment.
The home fitness equipment industry is dominated by devices that require extensive space and often target only one particular type of exercise. The products include motorized treadmills, stationary bikes, stairclimbers, rowing machines, elliptical cross-trainers, free weights and similar equipment. The popularity of such home exercise equipment is due in part to the fact that it allows users to train in the privacy of their own home without the necessity of visiting a commercial gym. The cost of the available home exercise equipment makes acquisition unaffordable for a large segment of the target market. To save costs, the existing products ship with a limited ability to modify the work load of the product, i.e., to add or remove the weight or resistance of the equipment so that the user can effectively complete an exercise. Indeed some devices, such as free weights, lack the ability to modify the work load of an exercise except in large increments (5 lbs, 10 lbs, etc). In addition, some equipment only allows the user to perform one repetitive exercise, which often leads to boredom and a lack of consistent use by the equipment's owners. There is therefore a need for a flexible, innovative and affordable device that can be used in a variety of exercises while allowing the user to adjust the workload of the device in small increments. The current invention is just such a device.
In the preferred embodiments, the exercise apparatus includes a pair of end cap assemblies, a plurality of disk assemblies and a plurality of weight assemblies. The plurality of disk assemblies and the plurality of weight assemblies are preferably secured between the end cap assemblies, in an alternating fashion. Each of the end cap assemblies also includes a handle that is preferably aligned in the same plane the handle of the other end cap assembly.
As depicted in
The selected assemblies are connected together by connecting the male connectors 314 of the selected weight assemblies 300 to the female connectors 120 of the disk assemblies 100. In the preferred embodiment, this connection is accomplished by pressing the plurality of locking flanges 126 of the female connector 120 into the groove entry points 319 of a selected side 314 of a selected male connector 310 and rotating that male connector 310 so that the locking flanges 126 travel along and within the locking groove 316 of that side 314 of that male connector 310 until the locking flanges 126 reaches the locking ridges 318 of the locking groove 316. Additional rotational force is used to move the locking flanges 126 past the locking ridges 318. Once past the locking ridges 318, the locking flanges 126 cannot move within the locking groove 316 without using a substantial amount of rotational force in a direction opposite to that used to originally move the locking flange 126 past the locking ridge 318. It is in this manner that the selected male connector 314 and selected female connector 120, as well as their respective weight assembly 300 and disk assembly 100, are then effectively connected to each other.
It is to be understood that even though numerous characteristics and advantages of various embodiments of the present invention have been set forth in the foregoing description, together with details of the structure and functions of various embodiments of the invention, this disclosure is illustrative only, and changes may be made in detail, especially in matters of structure and arrangement of parts within the principles of the present invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed. It will be appreciated by those skilled in the art that the teachings of the present invention can be applied to other systems without departing from the scope and spirit of the present invention.
The present application claims the benefit of U.S. Provisional Patent Application No. 61/201,712, entitled “Exercise Apparatus,” filed Dec. 12, 2008.
