Definitions
- the invention relates to a device mountable to a rail, so that means for screening off the railway can be connected to a number of spaced apart devices, said device comprising a connecting bar extending almost horizontally during use of said device, in which the end of said connecting bar can be slid under the rail and be fixed to the rail foot, and said connecting bar carries an upright at a distance from the end connected to said rail foot.
- a difficulty of said known structure is that the connection of the end of the connecting bar to the rail has to occur through means mounted near the rail. Therefore, during said work, one has to make sure that there are no trains approaching. Further, said known structure is not very stable since the connecting point is situated at a considerable distance from the upright, whereas said upright must be able to absorb loads.
- the object of the invention is to remove this difficulties and to that end provides for, that the end of the connecting bar to be slid under the rail is provided with a hook portion that, after sliding it under the rail, can embrace the rail foot, the connecting bar being provided with a lock pivotably connected to it at a distance from said hook portion, said lock being able to embrace the other side of the rail foot and being operable with the help of a coupling bar pivotably connected to it and also pivotably connected to a connecting piece being in turn pivotably connected to the connecting bar, in which said coupling bar can extend towards the upright at an angle with the connecting bar and can be fixed to said upright at a distance from the connecting point between connecting bar and upright, after locking of the end portion of the connecting bar to the rail foot has taken place, in which all pivot axes are square to the plane going through the connecting bar and the upright.
- the connecting piece in the locked state of the device, extends almost parallel to the connecting bar and that the pivot point between the coupling bar and the connecting piece is situated closer to the free end of said connecting bar than the pivot point between said connecting bar and said connecting piece.
- the free end of the connecting bar On mounting the device to the rail, first the free end of the connecting bar is slid under the rail and then pulled back slightly in order to bring the hook portion around the rail foot. Subsequently, by means of a relatively small movement of the coupling bar, the lock can be pivoted across the rail foot. Then, the free end of the coupling bar is situated at a considerable distance from the rail, so that, on mounting the device onto the rail and locking it, one can remain at a distance from the rail. After movement of the coupling bar, to wit substantially in longitudinal direction thereof, its free end will contact the upright in a certain place and it can be fixed to it.
- the coupling bar between the connecting bar and the upright By the presence of the coupling bar between the connecting bar and the upright, the latter is supported in a better way, so that it is able to absorb higher loads, also in case of a lightweight version.
- a pin which is slidable substantially in longitudinal direction of the coupling bar and which is pressed outwardly and out of the end of the coupling bar by a spring and which can be received in a bore in the upright.
- a further bore for passing tools by means of which the pin can be pushed back can be provided opposite the bore in which the pin is received.
- the connection between the coupling bar and the upright can be removed, and the device can be removed from the rail. It can be provided for, that the pin can be pushed back by special tools only.
- the hook portion situated at the free end of the connecting bar is connected to a bush which is slidably yet not rotatably mounted to the connecting bar and can be brought at the appropriate distance from the lock by means of a bolt.
- both the connecting bar and the coupling bar are electrically insulated from the rail, since the rail can be live and said bars must be touched with the hands.
- the bushes can be mounted between the telescoped portions of the bars by bonding.
- the device 1 shown in the drawing consists of the connecting bar 2 changing to the upright 3 by means of a bend.
- the device is fixed to the rail 4 in a way to be described further.
- the connecting bar 2 is provided with an end piece 6 being secured in it by means of a bush 7 of electrically insulating material.
- the end piece 6 is provided with the pivot point 8 in which lock 9 is rotatable, provided with a hook 10 which can fall across the rail foot. Operation of the lock 9 takes place by means of the coupling bar 12.
- Said bar 12 is provided with an end piece 13 being mounted in the bar by means of a bush 14 of electrically insulating material.
- the end piece 13 is pivotably connected to the lock 9 at the point 15.
- said end piece 13 is pivotably connected to a connecting piece 17 which at the other side, at the point 18, is pivotably connected to the end piece 6 of the connecting bar 2.
- a bush 19 guided by a pin 20 mounted in the end piece 6 is slidable on the end piece 6.
- the bush 19 carries the hook portion 22 that can grasp around the rail foot 11.
- the device can be applied with rails having a varying width of the foot. Since the bush 19 can be mounted in the correct place on the end piece beforehand, no work needs to be done near the rails 4.
- Fig. 3 shows the position of the parts 9, 12, 13 and 17 when they are in the unlocked position before the lock 9 can be clamped onto a rail.
- the bar 12 When the device must be clamped onto the rail, the bar 12 will be moved from the position shown in fig. 3 into the position of fig. 1. With unlocking, the coupling bar 12 will be pivoted in the direction of the arrow R in fig. 1 and after that be pulled back in its longitudinal direction.
- Fig. 4 shows the way of securing the coupling bar 12 to the upright 3.
- the coupling bar is provided with a pin 23 slidably received therein, which is pressed out by a spring 24 and can be accomodated in a bore 25 in the upright 3. From the other side of the upright 3, the pin can be pushed back against the action of said spring 24. This can be realized through a tool that can be brought into a bore 26 and can be moved in the direction of the arrow P.
- dash lines T show the profile which must be available for a train, and within which no objects are allowed.
