EXTENDABLE RAIL SYSTEM ABSTRACT An extendable rail system is comprised of a support beam, a slide beam and a storage beam. The slide beam and storage beam extend horizontally and are supported by load rollers at one end and by a grooved roller at the other end. The grooved roller of the slide beam mates with an extension of the support beam. The grooved roller of the storage beam mates with an extension on the slide beam. The slide beam includes first and second lateral flanges in parallel spaced relation extending from opposite sides of the slide beam to form opposite tracks along the inner sides of the flanges. A first set of roller members attached to the support beam, roll along the inner tracks of the first flange to hold the slide beam adjacent the support beam. A second set of roller members, attached to the storage beam, roll along the inner tracks of the second flange to hold the storage beam adjacent the slide beam. A brake is provided comprising a tube extending the length of the storage beam, a first member connected to the storage beam having first opening therethrough for slidable movement of the first member along the tube through the first opening and a second member having a second opening therethrough for slidable movement of the second member along the tube through the second opening. The second opening has an axis offset from the axis of the first opening. Twisting means rotatably attach the first and second members and twists the second member with respect to the first member to a position where the openings are in co-axial alignment. The first and second members are then slidable along the tube. The members are prevented from slidable movement along the tube through the openings when the openings are not in co-axial alignment.
