Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a windshield protection device for preventing freezing that is attached to the front of the windshield of an automobile. This invention relates to the windshield protection device, which is housed in a case that can be drawn out and rolled up in a case that can be attached vertically in the center.

(Prior Art) Conventionally, a cover member used to prevent windshields from freezing in outdoor parking lots in winter is a heat insulating sheet that has the required area to cover the front of a car's windshield. The most common type was one with a suction cup attached.

By the way, such conventional cover members made of heat insulating sheets are particularly troublesome to handle, so recently, in order to make them easier to attach to the windshield and store and carry, a vertical cover member that can be attached to the front of the windshield has been developed. It has been proposed that a take-up reel is built into the case, and the cover member is wound onto the take-up reel over its entire length.

(Problem to be Solved by the Invention) However, in the roll-up type windshield protection device as described above, a case in which a horizontally long cover member is rolled up and stored is attached vertically to one end of the windshield, and the case By fixing the pulled-out end of the cover member to the other end of the windshield with a suction cup, the cover member is attached with just two points of support, so the center part tends to roll up due to gusts of wind, etc. There was a problem that the adhesion deteriorated and the original anti-freezing function was lost.

In addition, with conventional windshield protection devices, the length of the cover to be pulled out is equal to or longer than the width of the windshield (usually 130 to 160 cm), making it difficult for a single occupant to install it. Ta.

The present invention was created by focusing on the problems that such conventional windshield protection devices had.
A case for winding and storing a cover member can be attached to the center of the windshield, and a cover member having a length half the width of the windshield can be pulled out from inside the case toward both sides and rolled up. By attaching the drawn-out ends of the case and the cover member to the front surface of the windshield via suction cups, the cover member is supported at three points along its entire length, thereby solving the above problem. This is something that we are trying to resolve.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be explained with reference to FIGS. 1 to 3 of the accompanying drawings.
