Patent Application
20220023700
The present invention relates to weights worn on the body and, more particularly, to tungsten-infused silicone gel body weights.
Current body weighted devices are made of sand, iron, lead or select gels. No such weight has the characteristics necessary to move with the human body. Body weighted devices overload the skin over a small surface area of the body. This leads to altered mechanics during human motion. They also often slide during use, leak, and are extremely rigid and/or bulky. If an athlete wears a weight vest while training, his or her trapezius muscles will hurt, and the athlete's posture is negatively affected. Wrist or ankle weights load the ankle bone and put all the added weight towards the foot. Currently, skate weights are attached to the skate boots. They throw off the player's stride because of the specific load position.
As can be seen, there is a need for a weighted device that is flexible, low-profile, moves with the human body, and distributes the weight along an extremity.
In one aspect of the present invention, a flexible body worn weight device is provided comprising tungsten powder suspended within a silicone rubber substrate, said flexible body worn weight device being operative to evenly distribute weight along a length and a circumference of a region of a user's body and being operative to move with the user's body.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description, and claims.
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Broadly, one embodiment of the present invention is a high-density, flexible body worn weight device comprising tungsten-infused silicone-gel which provides a balanced weight distribution.
The inventive weights are sometimes referred to herein as “TiG”, which stands for “Tungsten Infused Gel”.
TiG spreads the weight and is operative to evenly distribute the weight along the length and circumference of a calf or forearm. Because it is a silicone-based weight, it is customizable and may be molded into any shape. Body weighted devices comprising the tungsten-containing silicone-based material may be formed into breathable configurations to maximize air flow. The weights are also washable with warm water.
The inventive body weights may be worn on specific body locations to improve overall health and fitness, or they may be worn over multiple regions of the body, simulating increased gravity. TiG body weights may also take the form of weighted insoles, weighted grips, weight shoe soles, and weighted gloves. TiG is perfect for hockey.
The inventive weight material comprises a silicone gel, such as Ecoflex™ 00-33 AF, an anti-fungal silicone rubber made by Smooth-On, Inc.™. Formed weights may also be coated in Ecoflex™ anti-fungal silicone rubber. The silicone rubber substrate is flexible and stretchable such that it moves with the user's body, and it may be sewn into compression fabric for a comfortable, secure fit. It is also waterproof and skin safe.
The inventive weight material also comprises tungsten powder. The tungsten particles are suspended within the silicone rubber substrate. TiG's high density provides a slim profile so that the weights may be worn discretely. The tungsten content makes the inventive weights heavier than iron or lead. TiG may include sufficient tungsten to be characterized by a density of up to about 16 g/cm3. In comparison, the density of pure iron is 7.874 g/cm3 and the density of lead is 11.29 g/cm3.
In some embodiments, iron powder may be added to increase the part's rigidity as well as to lower the cost. Iron may also be added to increase volume within a mold.
A method of making the inventive weight may include the following steps. The silicone ingredients may be mixed according to the manufacturer's instructions. Vacuum degassing produces silicone with no air which improves mixing. While mixing the silicone, tungsten and/or iron powder may be added in a predetermined ratio. In some embodiments, coloring may be added. Once thoroughly mixed, the composition may be degassed in a vacuum chamber a second time and the TiG liquid may be poured, compressed, or injected into a mold of any shape. The composition generally cures in about 2 to 4 hours, depending on temperature (cure may be expedited with heat). The tungsten-infused silicone removed from the mold may be recoated in skin safe Ecoflex™ anti-fungal silicone rubber before being used as a body weight device. The structural integrity of the body weight device may be improved by increased mixing techniques, high purity metal powders, high compression, and durable steel molds. Tear resistance may be increased by injection or compression. The more tightly packed the particles are, the better TiG's tear resistance qualities become.

It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
