Patent number: 5673437Abstract: A vibration attenuating member includes at least a first layer composed of a viscoelastic material having a Shore 00 durometer of less than 50 and a rebound percentage of less than 20. Preferably the vibration dampener also includes second and third layers, coterminous with the first layer, which are composed of a foam material. The viscoelastic layer may have a non-uniform shape, such as precurved, tapered, or the like. The viscoelastic material may be creased to facilitate bending. The member has a transmissibility no greater than 1.0 in the range of from 31.5 to 200 Hz, and a transmissibility of no more than 0.6 in the range of from 200 Hz to 1250 Hz. The vibration attenuating member may form a glove, a glove liner, a portion of a glove liner, a portion of a glove, a sports glove, a wrap for a tool, or be used in some other application where vibration attenuation is desirable.Type: GrantFiled: May 6, 1996Date of Patent: October 7, 1997Assignee: Chase Ergonomics Inc.Inventors: David D.

Patent number: 5632045Abstract: An antivibration glove includes a glove body with a front and back and a vibration dampener essentially disposed in the interior of the glove toward the palm side of the glove. The vibration dampener has at least a first layer composed of a viscoelastic material having a Shore 00 durometer of less than 50 and a rebound percentage of less than 20. Preferably the vibration dampener also includes second and third layers, coterminous with the first layer, which are composed of a foam material. The viscoelastic layer may have a non-uniform shape, such as precurved, tapered, or the like. In one embodiment the layer of viscoelastic material is relatively thicker near the glove palm area and ball of the thumb and relatively thinner adjacent the finger portion of the glove. The viscoelastic material may be creased to facilitate bending of the glove. The glove attenuates at least 40% of the applied vibration occurring in the range of from 200 Hz to 1250 Hz.Type: GrantFiled: May 8, 1995Date of Patent: May 27, 1997Assignee: Chase Ergonomics, Inc.Inventors: David D.
