Track Guard Patents (Class 256/14)
  • Patent number: 9534347
    Abstract: Safety structure for protecting a railway line includes a fencing on supports resting on the track bed. These supports are connected to a rail of a railway line. The connection is effected by magnetic force. At their free ends, the supports have permanent magnets having a shape allowing them to engage the web of a rail. Due to the significant length of the supports, it is possible to apply a great torque to the magnets when the other end is engaged, that is to say that end which is turned away from the permanent magnets, as a result of which the magnet slides away along the web and can be detached therefrom. The magnet may consist of a number of magnets stacked on top of one another. The magnet is preferably arranged so as to be slightly displaceable with respect to the support to provide compensation for an uneven surface.

    Abstract: The device (20, 30) for securing railway tracks, which is formed by railway sleepers (11) to which parallel rails (12) are placed, on which track running vehicles such as trains, city light rails, trams, etc., traffic. The device (20, 30) is designed to prevent animals or humans from loitering on the tracks. The device (20, 30) includes elevations (21) which stretch between the rails (12). The elevations (21) are placed permanently on or integrated into the railway sleepers (11, 20), or the elevations (21) are placed between the conductor rails (22) that are attached to the sleepers (11, 20). The elevations (21) are placed at reciprocal distances and form elevations on the tracks which make it uncomfortable for humans and animals to walk on them.

  • Publication number: 20120037866
    Abstract: Safety structure for protecting a construction including a rail extending along the construction, includes a fencing supported on supports resting on the track bed. These supports are connected to a rail. The connection is effected by a magnetic force. At their free ends, the supports are provided with permanent magnets having a shape such that they can be brought into engagement with a surface part of the rail. Due to the significant length of the supports, it is possible to apply a great torque to the magnets when the other end is engaged, that is to say that end which is turned away from the permanent magnets, as a result of which the magnet slides away along the web and can be detached therefrom. The magnet may include a number of magnets stacked on top of one another. The magnet may be slightly displaceable with respect to the support.

  • Patent number: 5131631
    Abstract: A portable pitless livestock barrier whereby vehicles or humans may easily gain access to a livestock enclosure but provides a deterrent to the unwanted passage of the livestock from such enclosure. The barrier is provided by having a horizontal main frame to be placed on the ground with a vertical frame supported and attached to each side of the main frame. Within the boundaries of the main frame are two platform grates that are connected to the main frame at the exit and entrance to the barrier but can be adjustably raised in the central area of the barrier by a spring biased lever lifting mechanism attached to each vertical frame which allows the platform grates to be forced to the ground when a vehicle passes over but when the vehicle has passed the grates regain their inclined position giving a perception of depth or poor footing to the livestock thereby providing a deterrent to their passage.

  • Patent number: 5099610
    Abstract: A portable livestock barrier is disclosed which includes a rigid metal panel of open grid construction that is arranged to rest in a normal operational position that is parallel to the ground to thus form a raised grid which livestock will not cross but which can be flattened to the ground against a resilient return force when a vehicle is driven across it. The rigid metal panel is supported by a resilient suspension which permits the panel to tilt with respect to its normal operating position and to be forced flat against the ground when the weight of a vehicle is applied to it. The livestock barrier does not require a pit or special surface preparation for its installation. It may be quickly installed on any solid, relatively level surface. The unit is transportable and it can be readily moved from one location to another without disassembly.

  • Patent number: 4844423
    Abstract: A Portable Cattle Guard is provided which includes an assembled rectangularly shaped base member. Contained within the confines of the base member are a pair of inclined spring biased cattle ramps moveably connected along their longitudinal axis to provide a slight apex when in the relaxed state. The base member includes a pair of hollow vertical posts having inwardly facing guide slots cut therein. Each hollow post contains a coiled spring fixed at its upper end to the upper section of the post. The other end of the spring is connected to an end section of a leading bar of one of the ramps which is sufficiently extended to enter each of the guide slots. When a vehicle is driven on the spring-biased ramp, the ramp is flattened so that it is substantially parallel with the ground surface. When the vehicle passes over the ramp, the extended spring returns the ramp to its normal relaxed apex forming position.

  • Patent number: 4655435
    Abstract: A cattle guard has a grid with a plurality of spaced bars lying transverse to the direction of travel across the guard. The bars are supported by a plurality of spaced beams lying beneath the bars. The grid, in turn, is supported by a base in the ground. The base comprises a pair of side members positioned transverse to the direction of travel across the guard. Each of the side members has a side wall with a box-like flange member lying normal to the side wall and extending into the base. The grid rests on the flange member when the cattle guard is assembled and retained in position with respect to the base by locking elements. A plurality of columns extend between upper and lower walls of the flange member to support the grid. The base has a pair of end walls fastened to the side members during installation to complete the construction of the base.
