Title:
A REFLECTING TUBE DEVICE TO BE FIXED AROUND A TRAFFIC SIGN POST
Document Type and Number:
WIPO Patent Application WO/1990/004190
Kind Code:
A1
Abstract:
Reflecting means for increasing the visibility of for instance refuge poles are in the present form made of a flat plate, which forms a triangle around the pole and the plate is provided with a reflecting tape having blue and white colour. It is now proposed that the reflecting tape is provided on a plastic tube (1) which is axially cut (at 4) and has a triangular notch (5) at the bottom. By this design it is possible to assemble the reflecting means laterally on the pole and its attachments. Because the plastic tube (1) is inclined to form an ''overlap''-shape after having been cut, the tube will press against the attachments (2 and 3) in each of the ends of the tube by its own strength.

Description:
"< A reflecting tube device to be fixed around a traffic sign post

The present invention relates to an arrangement at reflecting 5 tubes which are attached around a traffic pole, and which tube has a slit along its entire length and which has a triangle formed notch in one end of the slit, whereby the pole with the help of the notch can press apart the tube in order to force the tube around the pole and whereby the tube consists of a 10 flexible material having the property to be able to be defor¬ med and be able to form an "overlap"-Bhape <fig. 2) .

The visibility for reflecting tape located on tubes in cσmpa- ration with the visibility of the reflecting arrangements uβed 15 today can be seen from the VTI-repσrt No. 380 of February 2 1988.

In order to be able to shift reflecting means, the reflecting means has been given the features which are stated in the 20 following claim.

This invention thus relates to a tubular reflecting tube 1 consisting of polyethylene. The polyethylene tube has two important properties which should be noted and these are that 25 after the tube has been cut along its whole length it has the capability to form an "overlap"-shaρe (see fig. 2) and resume its "overlap"-shape when the deformation (having been pressed apart) is ceased. A blue and white reflecting tape is glued to the envelope surface around the polyethylene tube. The so 30 formed reflecting tube is fixed on a certain hight on the pole by means of an attachment 2 , 3 in the top and in the bottom respectively which can be seen from fig. 1. As can be seen from fig. 2 the reflecting tube has been cut along the line 4 over its whole lenght and a triangular notch 5 has been formed ^35 at the bottom (see fig. 1).

Because thousands of poles and reflecting means are damaged yearly, it is of course valuable when the reflecting means are cheap as well as have a good function. They should simulta¬ neously be simple to assemble and it should be simple to shift them when they have been damaged. When shifting a re¬ flecting tube of this kind, the tube is drawn from the pole lateraly, whereby the reflecting tube is stretched apart in order to be able to pass over the pole.

When a new reflecting tube shall be mounted the triangular notch 5 is first pressed against the pole, whereby the reflecting tube opens, thereafter the reflecting tube is pressed against the pole along its whole length and the reflecting tube opens over its total lenght so much that the opening of the reflecting tube can pass over the pole. When shifting a reflecting tube of this kind it is thus only needed to draw the old pipe from the pole and press on the new reflecting tube in the axial direction without the necessity of undoing the attachments. Because the polyethylene pipe has the capability to form the "overlap"-shape it now presses by its own strength against the attachments 2 and 3 in the both ends, which leedε to that the pipe is fixed firmly without a need of being astened with screws .
