Description

[Detailed Description of the Invention] The present invention is used as sunglasses or as a sunshade by being attached to a sun visor attached to the front of the driver's seat or passenger seat of an automobile.

Conventionally, this type of light shielding device has been commercially available, in which a mounting edge is provided at the upper end of the light shielding plate, and a bearing is provided on the back of the root of a hairpin-shaped elastic clamping piece at both ends of the mounting edge, and the bearing portion is rotatably mounted. However, this device has no problem when rotating the light shielding plate attached to the sun visor forward (toward the windshield) relative to the sun visor, but when trying to rotate it in the opposite direction, Since the upper end of the light-shielding plate hits the root of the elastic clamping piece, if the light-shielding plate is forced to rotate, the light-shielding plate may crack.

In addition, when attaching the elastic clamping piece to the mounting edge, the bearing of the clamping piece is simply fitted with a pivot shaft of the same diameter as the hole. When the bearing's elasticity decreases, the light-shielding plate naturally rotates due to vibrations while the vehicle is running, which can interfere with driving.

The present invention aims to eliminate such drawbacks, and one embodiment thereof will be explained based on the drawings. 1 is a light-shielding plate made of a colored transparent plastic plate, and the color density and color can be adjusted as appropriate. be.

Further, reference numeral 2 denotes a mounting edge having a keyhole-shaped cross section fixed to the center of the upper end of the light shielding plate 1, and a groove 3 bored in the longitudinal direction at the lower end thereof is fitted onto the upper end of the light shielding plate 1 and is attached using adhesive. It's stuck.

Reference numeral 4 denotes a pair of left and right pivots whose roots are buried in both left and right ends of the mounting edge 2 and whose tips project outward horizontally, and a head with a larger diameter is attached to the tip of the protrusion 4'. 4".

Reference numeral 5 denotes a pair of elastic clamping pieces molded into a hairpin shape from hard plastic, and a bearing part 6 is integrally formed near one side of the back surface of the root part.

The bearing 7 is a hole bored in the portion 6 and fitted into the protruding portion 4' of the portion 4, and the inner diameter of the bearing is approximately the same as that of the protruding portion 4'.

8, the bearing is connected to the end surface of the mounting edge 2 side of the portion 6 and the elastic clamping piece 5.
This is a notched stepped portion formed by the back surface of the root and fits into the end of the mounting edge 2.

Reference numeral 8' denotes a locking edge for rotation control that protrudes from the lower end of the back surface of the root of the elastic clamping piece 5 into the notch step 8, and when the elastic clamping piece is in an upright state with respect to the hanging light shielding plate 1. The locking edge 8' engages with the front surface of the end of the mounting edge 2 to control the rotation of the light shielding plate 1.

Reference numeral 9 denotes a split groove that communicates from the hole 7 to the inner side of the root of the elastic clamping piece 5.

Reference numerals 10 and 11 indicate a through hole and a screw hole drilled in the bearing portion 6 in a direction perpendicular to the split groove 9, and 12 a tightening hole inserted into the through hole 10 and screwing its tip into the screw hole 11. It's a screw.

Reference numeral 13 is a sun visor whose upper end is rotatably attached to the front end position of the ceiling plate 14 of the automobile, and 15 is a windshield.

Next, how to use the above embodiment will be explained.

First, as shown in FIG. 1, a pair of left and right elastic clamping pieces 5, 5 are clamped to the tip of the sun visor 13 to fix the light shielding plate 1.
The sun visor 13 is tilted downward as shown by the solid line in FIG. 1, and the light shielding plate 1 is hung in front of the driver's eyes to be used as sunglasses, and as shown by the chain line in FIG. The sun visor 13 is rotated toward the windshield 15 side, and the light shielding plate 1 is attached to the windshield 15 to be used as a sunshade. 13 and then folded together with the sun visor 13 inside the ceiling board 14.

Since the light shielding device according to the present invention has the above configuration,
It is extremely effective for both eye hygiene and safe driving during the summer when the sun's rays are strong.Especially, the bearings of the pair of elastic clamping pieces are drilled in the holes and inside the roots of the elastic clamping pieces. A split groove was provided across the area, and a screw was screwed into the bearing to pass through the split groove, so by adjusting the screw, the light shielding plate could always be kept at the ideal hardness. Can be pivoted to the sun visor.

In addition, a locking edge for rotation control was provided on the back of the root of the elastic clamping piece, and this was made to correspond to the front of the end of the mounting edge, so that the light shielding plate could be unfolded in the folded state shown by the chain line in Figure 1. , 6th
When attempting to rotate it further in the direction of the arrow than the fully open state shown in the figure, the locking edge engages with the front end of the mounting edge to prevent further rotation, and the light shielding plate moves to the elastic clamping piece. It will not cause cracks or cracks in the light shielding plate due to the straining effect caused by direct collision with the windshield, and if it is used as a sunshade along the windshield as shown by the chain line in Figure 1, it will not cause vibrations while driving. Since the light shielding plate does not naturally rotate toward the driver due to its own weight and interfere with driving operations, we are confident that it is ideal as a light shielding device for a car sun visor.
