Wind-shield blind system

A wind-shield blind system for thermally insulating a car wind-shield comprising:

• a roller blind mechanism having an elongated tubular member carrying an opaque plastic blind and end plugs non-rotatably attached to opposite ends of the tubular member, wherein a first end plug of said end plugs is formed with a central passage extending axially therethrough and a second end plug is formed with a toothed rim at outer side thereof and an axial cylindrical recess extending outwardly;
• a rod member adapted to extend through the central passage of the first plug, which is rotatable about the rod member, and having a first end and a second end;
• a helical spring disposed around the rod member;
• means for fixing one end of the helical spring to the first end of the rod member and the other end of the helical spring to the first end plug;
• means for interconnecting two end cap members which are arranged in spaced-apart relation, wherein a first end cap member is axially provided with an aperture means for non-rotatably receiving the second end of the rod member and a second end cap member formed with a central passage extending axially therethrough and a toothed rim at an inner side thereof adjacent to and meshable with the toothed rim of the second plug to serve as a catch to the toothed rim of the second plug for preventing the tubular member from rewinding after having been driven to extend the blind thereon;
• and
• a control means having an axle extending through the central passage of the second plug and into the cylindrical recess of the second plug, which is rotatable about the axle, and enabling the roller blind mechanism to be displaced on said rod member between a first position, wherein the adjacent toothed rims of the second plug and the second end cap member are in spaced-apart relation, and a second position, wherein the adjacent toothed rims are in interengaged state.
