Title: Stretchable Cover For Exercise Device And / Or Equipment

Description:
1. FIELD OF THE INVENTION 
     The present invention relates to exercise equipment; and more particularly to a cover that encases at least a portion of the equipment to enhance functionality, mitigate the transmission of germs and facilitate a healthy, hygienic environment. 
     2. DESCRIPTION OF RELATED ART 
     Exercise equipment shared in a gym or club environment can become contaminated with germs, virus and sweat droplets from users. Particularly, such exercise equipment as elliptical trainers can involve upper body movement that requires bodily contact with components such as cylindrical handles. Likewise, some stair climbers, steppers and treadmills involve upper body contact with handles. These handles frequently become unsanitary, harboring germs and virus with repeated use. 
     Moreover, various exercise devices are repeatedly utilized in yoga classes. During these classes, yoga blocks, mats, and foam rollers come into direct contact with the user&#39;s body. Yoga blocks are blocks appointed to help an individual hold poses for increased amounts of time, providing space, length and comfort. These yoga blocks are also frequently utilized for therapeutic stretches and/or poses. Yoga blocks generally provide basic functions, including balance and increased flexibility. They help to maintain balance by providing support and comfort during longer yoga pose positions. Generally, yoga blocks are composed of wood, foam or cork materials. Wooden yoga blocks are often hollow and are made from bamboo, birch, maple, pine, balsa and poplar. Wood and bamboo yoga blocks provide excellent support, are very durable, and are environmentally friendly; however they are often heavy, uncomfortable to use, prone to becoming slippery when wetted with sweat, and tend to absorb sweat odors over time. Cork yoga blocks are generally lighter than wood blocks, and have been found to be durable, more comfortable than wood, good for extra grip/traction on smooth surfaces (such as wooden floors), environmentally friendly and absorb somewhat less sweat. Nevertheless, cork blocks tend to disintegrate over time and, although having porous properties that aid in absorbing sweat, they exhibit an absorptive rate that causes the blocks to become moist with sweat during use. Most yoga blocks are composed of various types of foam. Foam yoga blocks are lightweight, durable, comfortable, versatile and cost effective. They have the disadvantage of being less environmentally friendly than the wood and cork blocks and, like wood and cork blocks, also become unhygienic and unattractive owing to the absorption of sweat and body secretions over time. 
     Typical yoga blocks suffer from a variety of problems. During use, they become slippery with sweat; this causes the blocks to become less effective for their intended purpose, and to even become off-putting for the user. Owing to their construction, the blocks are not machine washable. Often yoga blocks are used time and again at yoga facilities or gyms without being disinfected. Such repeated usage in warm environments causes the blocks to become contaminated with germs, viruses and bacteria. This can be particularly dangerous and unhygienic, especially during the flu season. 
     Some examples of covers or devices heretofore disclosed and utilized in an attempt to make public exercise equipment more hygienic are set forth in summation below: 
     U.S. Pat. No. 5,099,530 to Scott discloses a washable fabric cover that fits over a folding exercise or rest mat or pad and can be folded with the pad inside into a compact package for carrying. The cover is a generally rectangular envelope having a head portion and a foot portion. It is enclosed at the end of the head portion and along its opposed longitudinal sides, remaining open at the end of the foot portion to form a top layer and a bottom layer of material. A pocket on the top layer at the head portion removably receives a pillow or other articles. A length of material extends outwardly from the open end to be folded over and substantially cover the top layer. This length of material serves as a blanket to cover a person laying on the covered pad; and can be folded and received within the open end in a stored condition. A pair of flexible loops is secured to the bottom layer to form carrying straps when the cover and the enclosed pad is in the compact package for carrying. The cover with the enclosed pad is a foldable accordion style such that the pocket is disposed on an outer side of the folded configuration or can be folded inwardly upon itself from each end such that the pocket is disposed on the inside of the folded configuration. Alternatively, the sheet portion may be removable and a second pocket may be provided on the bottom layer at the foot portion for storing the sheet portion or other articles. 
     U.S. Pat. No. 5,727,266 to Pang discloses a disposable pillow or cushion cover formed by an envelope of air and moisture impermeable material. The envelope encases the pillow or cushion and provides an impermeable resting surface upon which a user may rest the head or other body part on a clean, comfortable, fresh, hygienic, fragrant resting surface without having to change pillows, cushion covers or envelopes. The envelope contains a vent to permit ingress and egress of air from the pillow or cushion. The envelope also includes a sealable opening to permit insertion and removal of the pillow or cushion. A facing layer of air permeable material extends over the resting surface and is secured to the envelope at spaced apart locations to allow air flow and a degree of relative movement between the facing layer and envelope. 
     U.S. Pat. No. 6,065,164 to Swanger, et al. discloses a removable nap mat cover that is made of two fabric panels and has one end closed with an end fastener. The nap mat slips between the fabric panels. The end fastener secures the fabric panels together for about ⅔ of their width defining openings large enough for a person&#39;s hand to fit through. The end fastener prevents the nap mat cover from coming off the mat. The end fastener may be a hook and loop fastener. 
     U.S. Pat. No. 6,751,816 to Wechsler discloses an exercise mat ensemble for use in exercise disciplines such as yoga that involve floor exercises and positions. A vinyl padded sticky mat is covered with a sheet of washable absorbent fabric that overlays the sticky mat on all four sides. The fabric sheet may be extended at one transverse end with sufficient fabric that when folded over more than once it forms a cushion to aid in certain exercises and positions. When the fabric sheet is placed on top of the mat and the two are rolled together, the fabric extension encloses the mat within the roll. The extension may also be stitched to form an envelope or stitched on each side to form channels into which drawstrings are placed, both capable of forming a case around the rolled mat and fabric sheet. A strap may be added to the ensemble to assist in certain exercises and positions and also to be incorporated into the rolled mat and fabric sheet for use as a carrying strap. The fabric extension may also be separate from the main fabric sheet to increase the number of fold possibilities, to provide added assistance for specific exercises and positions, and to serve as a meditation blanket. A sheath may be used to cushion the strap for ease of carrying. 
     U.S. Pat. No. 6,766,536 to Aarons discloses a yoga support system including a pair of yoga gloves and a pair of yoga slippers. Yoga gloves cover the hands of a yoga practitioner and include anti-skid material on parts of the gloves to enable a yoga practitioner to attain and maintain postures that involve pressing on a floor or wall. In particular, the yoga gloves may include anti-skid portions covering an outer part (further from the midline of the hand) of the yoga practitioner&#39;s thumb. The yoga slippers include an anti-skid sole, as well as anti-skid side portions on their sides. The slippers allow a yoga practitioner to maintain floor contact, with the feet flat on the floor, or with the feet pronated or supinated. Other parts of the yoga gloves and yoga slippers are uncovered fabric, which may be a light, breathable and stretchable material. 
     U.S. Pat. No. 7,156,791 to Edwards discloses yoga grip blocks having one or more block sections and a grip section that provide support and comfort in the practice of yoga exercises.
