Weightlifting grip device and system for weightlifting exercising and training

Abstract

Exercise devices useful for weightlifting exercises and training are provided. More specifically, a weightlifting exercise device and system is provided for improving the grip and support of a weightlifting bar or barbell when in use. The present exercise device provides the user with a better grip on the weightlifting bar, while enabling the user to change hand positions along the weightlifting bar to vary the exercise routine or accommodate the physical requirements of the user. The weightlifting exercise device is designed to fit easily around the circumference of weightlifting bar or barbell. The present exercise device is also portable and easy to store.

         2 . The weightlifting grip device of  claim 1 , wherein the outer surface of the body is configured for a hand of a user. 
     
     
         3 . The weightlifting grip device of  claim 2 , wherein at least one finger of the hand of the user extends beyond the width of the outer surface of the device when the hand engages the device. 
     
     
         4 . The weightlifting grip device of  claim 1 , wherein the device further includes a strap on the outer surface. 
     
     
         5 . The weightlifting grip device of  claim 5 , wherein the strap is configured for receiving a hand of a user. 
     
     
         6 . The weightlifting grip device of  claim 1 , wherein the inner surface of the device has a concave surface having a radius configured to receive a weightlifting bar. 
     
     
         7 . The weightlifting grip device of  claim 1 , wherein the at least one roller is embedded within a portion of the opening on the inner surface. 
     
     
         8 . The weightlifting device of  claim 1  wherein the at least one roller is configured to move the device laterally along a length of a weightlifting bar. 
     
     
         9 . The weightlifting grip device of  claim 1 , wherein at least two sets of rollers are positioned within openings within the inner surface. 
     
     
         10 . The weightlifting grip device of  claim 1  further comprising:
 an elastic tube holding element on an end of the semi-cylindrical body, the elastic tube holding element comprising a first jaw, an opposing second jaw, and a passage between the first jaw and the second jaw, wherein the elastic tube holding element is configured to hold an elastic tube within the passage between the first jaw and the second jaw. 
 
     
     
         11 . The weightlifting grip device of  claim 10  wherein the passage comprises a spheroid seat on at least one end thereof, wherein the spheroid seat is configured to sit a bulb end on an elastic tube. 
     
     
         12 . A weightlifting exercise system comprising:
 an elongated bar having a first end and an opposing second end, the first end and second end configured for receiving a plurality of removeable weights;   a gripping device configured for engagement with a hand of a user and the elongated bar, the gripping device comprising:   a semi-cylindrical body having an outer surface and an inner surface;   an opening within the inner surface; and,   at least one roller embedded within the opening in the inner surface,   wherein the at least one roller contacts the elongated bar received within the inner surface.   
     
     
         13 . The weightlifting exercise system of  claim 12 , wherein the outer surface has a width for engaging a portion of the hand of the user. 
     
     
         14 . The weightlifting exercise system of  claim 12 , wherein the inner surface has an inner radius for receiving the elongated bar. 
     
     
         15 . The weightlifting exercise system of  claim 12 , wherein the at least one roller is positioned within the opening at a depth for contacting with the elongated bar when the elongated bar is within the inner surface. 
     
     
         16 . The weightlifting exercise system of  claim 12  further comprising:
 an elastic tube holding element on an end of the semi-cylindrical body, the elastic tube holding element comprising a first jaw, an opposing second jaw, and a passage between the first jaw and the second jaw, wherein the elastic tube holding element holds a first end of an elastic tube within the passage between the first jaw and the second jaw. 
 
     
     
         17 . The weightlifting exercise system of  claim 16  wherein the passage comprises a spheroid seat on at least one end thereof, wherein the spheroid seat is configured to sit a spheroid end of the elastic tube. 
     
     
         18 . The weightlifting exercise system of  claim 16  further comprising:
 a clamp configured to clamp to the elongated bar, the clamp comprising a second elastic tube holding element, wherein the second elastic tube holding element comprises a third jaw, an opposing fourth jaw, and a second passage between the third jaw and the fourth jaw, wherein the second elastic tube holding element holds a second end of an elastic tube within the second passage between the third jaw and the fourth jaw. 
 
     
     
         19 . A weightlifting exercise apparatus comprising:
 a grip element configured to engage a user's hand; and   an elastic tube holding element comprising a first jaw, an opposing second jaw and a passage between the first jaw and the second jaw, wherein the elastic tube holding element holds an end of an elastic tube within the passage between the first jaw and the second jaw.
