Abstract
The present disclosure relates to a system and method for non-invasively attaching components to railroad track rails. More specifically, an anchor is provided that securely fastens to the track rail in a non-invasive manner for holding one or more signal lines to a surface of the track rail. In one embodiment, the non-invasive anchor utilizes a compressive force to clamp to a flange portion of the track rail. In this regard, first and second body members of the anchor may be advanced toward the toward opposing surfaces of track rail to compress the component between a portion of the anchor and a surface of the track rail. In one embodiment, a pawl prevents the withdrawal of these body members from one another such that the compressive force may be maintained once the anchor is applied to the track rail.
Claims14
An anchor for use in connecting a component to track rail, comprising:
- a first body member having a first rail contact surface for engaging a first rail surface;
- a second body member having a second rail contact surface for engaging a second rail surface and receiving channel for receiving an insertion end of the first body member, wherein said first and second body members are slidably connected for movement between an open position and a closed position;
- a spring pawl attached to said insertion end of said first body member, said spring pawl having a flexible body wherein a free end of said flexible body is compressed against an engagement surface of the second body member as said first and second body members slide relative to one another between said open position and said closed position, wherein said flexible body of said spring pawl is disposed at an acute angle relative to said engagement surface and where said acute angle has a first component that is in a direction opposite of a direction of movement of said first and second members between said open position and said closed position wherein said pawl permits movement between said body members in substantially a single direction and wherein said pawl is adapted to engage said engagement surface to fix a relative position of said first and second body members continuously between said open position and said closed position.
An anchor for use in connecting a component to track rail, comprising:
- a first body member including a rail engaging end adapted to engage an outside edge surface of a track rail and a receiving end having a receiving channel;
- a second body member including a rail engaging end adapted to engage an outside edge surface of a track rail and an insertion end for insertion within said receiving channel of said first body member, wherein upon initial insertion of said second body member into said receiving channel of said first body member said anchor is in an open position and wherein said second body member can advance relative to said first body member to a fully closed position;
- and
- a pawl attached to said insertion end of said second body member, wherein said pawl is a spring member having:
- an L-shaped flexible body with a first leg attached to said insertion end of said second body member and a second leg having a free end, wherein the second leg is compressed relative to the first leg upon said insertion end being disposed within said receiving channel and wherein upon said insertion said free end is compressed against and engages an engagement surface along the length said receiving channel to prevent withdrawal of said second body member from said first body member when said insertion end is inserted within said receiving channel and wherein said pawl is adapted to engage said engagement surface to fix a relative position of said first and second body members continuously between said open position and said fully closed position.
