Abstract:
The invention relates to an adjustable safety distance spacer for bicycles, comprising two guide tubes ( 1, 2 ), a spacer rod ( 5 ) which moves inside the aforementioned guide tubes and which passes through perforated plugs ( 9 ), a refracting rotor comprising four curved blades ( 7 ) and a circumferential protector ( 6 ) which is disposed at one of the ends of the spacer rod and which is solidly connected to said rod by means of a safety clevis ( 8 ), and two supports ( 3, 4 ) which are used to fix the guide tubes ( 1, 2 ) to the bicycle frame ( 10 ). In this way, the cyclist can adjust the size of a safety signal strip quickly, comfortably and safely using just one hand when he/she is being overtaken by another vehicle, thereby preventing the cyclist from being hit owing to the incompetency or carelessness of the driver of the overtaking vehicle.

Description:
OBJECT OF INVENTION  
       [0001]     The present invention is referred to one adjustable safety distance spacer for bicycles which is fastened by supports to the bicycle frame. It allows the cyclist to signpost with any of the two hands, in a fast, comfortable and safe way, the situation of the minimal distance of security when he is overtaken by another vehicle. This distance depends on the characteristics of the road surface, thus it guarantees not to be collided by incompetence or careless of the drivers when they overtake, establishing a strip of security between the lateral border of the cyclist and the one of the vehicle that overtakes.  
       BACKGROUND OF INVENTION  
       [0002]     The distancers that we have known until now are fixed, are not able to include the whole of the minimal distances shown in the present-day Traffic Law. This distance of 1.5 meters, is lateral, and is not adjustable when we want to signpost, so the use of the distances present a great inconvenience since they cannot be adapted to the constant changes of the traffic and road surfaces, with the resulting risk to cause impact against another vehicle, pedestrian or static objects, risking the stability of the bicycle and the cyclist&#39;s security.  
         [0003]     Those functional and utilization deficiencies don&#39;t exist in the present invention which is totally innovative for its forms, way of use and effectiveness when we want to safeguard the security of the cyclist who is overtaken by another vehicle. This gadget allows to regulate the distance of security which goes from 0 meters to 1.5 meters, its movable elements refract the light and allow to detect the presence of the cyclist on the road, even during the night, increasing the security.  
       DESCRIPTION OF THE INVENTION  
       [0004]     The adjustable safety distance spacer for bicycles is an accessory to install in any kind of bicycles, since it can be adapted to the different frames. Its placing does not get in the way to manoeuvrability and therefore in the security when using the bike. It can also be used in wheelchairs.  
         [0005]     The adjustable safety distance spacer is formed by two guide tubes which are joined to the bicycle frame by two supports. These supports are adapted to all the frames found in the market. A thin spacer rod is placed inside the guide tubes. Its flexibility makes possible to adapt it to the forms of the tubes. This stick goes through the perforated plugs, which are placed at the every end of the guide tubes.  
         [0006]     In one of the ends of the thin spacer rod a refracting rotor is situated. This is formed by four curved blades which spin on its own axle when the air drafts get in. This refracting rotor allows to reflect the light received by other vehicles and this helps to signpost the distance of security during the night.  
         [0007]     Around the refracting rotor there is an antihooking protector, in a circumference form, which avoids the rotor to get hooked with those possible objects that accidentally may be touched on the way, such as, branches, posts or even vehicles.  
         [0008]     The aforementioned protector is fastened to the spacer rod by means of a hairpin which provides safety.  
         [0009]     When the thin spacer rod comes out of the guide tube, at the end, where is situated the refracting rotor with his protector, this one, by the form that the guide tube has, it becomes situated in a perpendicular plane to the plane that it contains the bicycle. The spacer rod can also be used as a support for other elements such as sidelights. At the end of the thin spacer rod there is a little sphere which makes easy the advance of the extreme of this stick in the inside of the guide tube.
