Exercise device for use in a doorway including resistance bands extending from slidable carriages

Abstract

An exercise device for use in a doorway including resistance bands extending from slidable carriages is provided. The exercise device includes a pair of vertical rail members attachable to sides of a doorway. Each vertical rail member is slidably engageable with a carriage. Resistance bands are connectable to the carriages. The resistance bands are additionally attachable to an athletic accessory such as a hand grip, belt, or crossbar. A pull-up bar may also be attached to the exercise device, the pull-up bar capable of vibration for enhanced performance.

         2 . The exercise device of  claim 1 , wherein the first and second vertical rail members are sized longitudinally to span a substantial portion of the first and the second sides of the doorway, respectively. 
     
     
         3 . The exercise device of  claim 1 , wherein the first and second carriages each further include a locking mechanism sized and configured to respectively engage with the first and second vertical rail members and to selectively lock the respective one of the first and second carriages into place at a desired location along the first and the second vertical rail members. 
     
     
         4 . The exercise device of  claim 3 , wherein each locking mechanism is a hand wheel clamp with an engagement member sized and configured to respectively engage the first and second vertical rail members, locking the first and second carriages into place at a desired location along the first and the second vertical rail members. 
     
     
         5 . The exercise device of  claim 1 , wherein the first and second resistance bands have a constant diameter. 
     
     
         6 . The exercise device of  claim 1 , wherein the first resistance band is attached to a hand grip. 
     
     
         7 . The exercise device of  claim 1 , further including a vibrating pull-up bar that is lockably attached to the first and second vertical rail members, the vibrating pull-up bar extending between the first and second vertical rail members and in a parallel relationship with the header of the doorway. 
     
     
         8 . The exercise device of  claim 1 , wherein the first and second vertical rail members are attachable to the doorway with threaded fasteners. 
     
     
         9 . The exercise device of  claim 1 , wherein the first and second resistance bands are formed from an elastomeric material. 
     
     
         10 . An exercise device for use in a doorway, the doorway defined by a door frame, the doorway having a first side, a second side parallel to the first side and a header perpendicular to and extending between the first and second sides, the exercise device comprising:
 a first vertical rail member attachable to the first side of the doorway;   a first carriage slidably engaged with the first vertical rail member, the first carriage being sized and configured to move longitudinally along the first vertical rail member; and   a first resistance band coupled to the first carriage.   
     
     
         11 . The exercise device of  claim 10 , wherein the first vertical rail member is sized longitudinally to span a substantial portion of the first side of the doorway. 
     
     
         12 . The exercise device of  claim 10 , wherein the first carriage further includes a locking mechanism sized and configured to engage with the first vertical rail member, locking the first carriages into place at a desired location along the first vertical rail member. 
     
     
         13 . The exercise device of  claim 12 , wherein the locking mechanism is a hand wheel clamp with an engagement member sized and configured to engage the first vertical rail member, locking the first carriage into place at a desired location along the first vertical rail member. 
     
     
         14 . The exercise device of  claim 10 , wherein the first resistance band has a constant diameter. 
     
     
         15 . The exercise device of  claim 10 , wherein the first resistance band is attached to a hand grip. 
     
     
         16 . The exercise device of  claim 10 , further including a vibrating pull-up bar that is lockably attached to the first vertical rail member. 
     
     
         17 . The exercise device of  claim 10 , wherein the first vertical rail member is attachable to the doorway with threaded fasteners. 
     
     
         18 . The exercise device of  claim 10 , wherein the first resistance band is formed from an elastomeric material. 
     
     
         19 . A method of configuring an exercise device in a doorway, the doorway defined by a door frame, the doorway having a first side and a second side parallel to the first side and a header perpendicular to and extending between the first and second sides, the method comprising:
 fixing a first vertical rail member to the first side of the doorway;   fixing a second vertical rail member to the second side of the doorway;   fixing a first carriage along the first vertical rail member, the first carriage slid longitudinally along the first vertical rail member and locked into place at a desired location by a locking mechanism;   fixing a second carriage along the first vertical rail member, the second carriage slid longitudinally along the first vertical rail member and locked into place at a desired location by a locking mechanism;   engaging a first resistance band with the first carriage; and   engaging a second resistance band with a second carriage.
