摘要： A deformable panel member is provided for absorbing the energy of a moving object impacting the panel member. The panel member is adapted to be connected to a rigid member and has a front wall, a rear wall and two side walls extending between and interconnecting the front and rear walls. A support member in panel member extends between and interconnects at least two of the walls. The side walls are adapted to be angled relative to the rigid member in a direction of movement of the object when the panel member is mounted to the rigid member. An impact on the panel member will tend to deform the panel member toward the rigid member in the direction of movement of the object. This deformation allows the panel member to absorb the energy of the object for decelerating and redirecting the object subsequent to impact. An energy absorbing barrier is also provided comprising a plurality of the panel members mounted at spaced intervals along the rigid member. The panel members are positioned in adjacent relation for allowing relative independent movement of the panel members upon impact. Impact of a panel member will transmit the force of the impact to adjacent panel members which are similarly deformed for successively absorbing energy and redirecting the object subsequent to impact at an angle relative to the rigid member less than the angle of impact.

摘要： The present invention is directed to a hub lock assembly for rotatably fixing a hub to a selectively powered rotating member. The hub lock assembly comprises a hub including a barrel having a bore therethrough defining internal splines. The hub lock assembly also comprises a spindle having a distal end defining external splines disposed within the barrel of the hub for rotatably supporting the hub. The spindle is adapted to be connected for rotation with the powered rotating member. The hub lock further comprises an actuator for switching the hub lock assembly between an engaged position where hub is rotatably fixed to the spindle and a disengaged position where the hub is free to rotate relative to the spindle. The actuator comprises a body member defining external splines and having a bore therethrough defining internal splines. The body member is disposed within the hub such that the external splines of the body member engage the internal splines of the hub for fixed rotation of the body member with the hub. The actuator also comprises a drive gear defining external splines and having a passage therethrough defining internal splines, the drive gear slidably disposed within the body member such that the external splines of the drive gear engage the internal splines of the body member for fixed rotation of the drive gear with the body member. The drive gear is movable within the body member relative to the hub and the spindle for moving the internal splines of the drive gear into an out of engagement with the splines on the distal end of the spindle. The actuator further comprises a cap that is adapted to be grasped and manipulated by a user. The cap is operatively connected to the body member for movement between an extended position for sliding the drive gear between the engaged position where the drive gear receives the distal end of the spindle and the internal splines of the drive gear are engaged with the external splines of the spindle for fixed rotation of the drive gar with the spindle, and a retracted position in the disengaged position where the drive is spared from the distal end of the spindle.
