AI Technical Summary

Benefits of technology

The present invention is a grinder that has two sides and two pieces of sandpaper. The first piece of sandpaper is used to quickly grind and smooth the tip of a rubber strip of a windshield wiper, while the second piece of sandpaper is used to make the tip smooth. The grinder has two marks on the sides to indicate different steps in the grinding process. The main advantage of this grinder is that it can quickly and effectively grind and smooth the tip of a rubber strip of a windshield wiper.

Problems solved by technology

However, after used for some time, the rubber strips of the windshield wipers will inevitably be hardened and fail to wipe rain from the windshields completely.
Later, users can only replace used rubber strips with new ones.
This conventional grinder has proven to be ineffective in removing a harden tip of a rubber strip of a windshield wiper.

Embodiment Construction

[0020] Shown in FIGS. 1 through 3 is a grinder for windshield wipers according to the preferred embodiment of the present invention. The grinder includes a top 10, a bottom 20, a first flank 15, a second flank 25 and two taper ends.

[0021] The top 10 is substantially a convex surface except a groove 16 defined in a middle portion 13 between two lateral portions 11. A first piece of sandpaper 18 is attached to the floor of the groove 16. Made on one of the lateral portions 11 of the top 10 is a mark 12 such as “STEP 1.” The mark 12 may be written, painted, embossment or intaglio. The mark 12 may be replaced with a sticker.

[0022] The bottom 20 is substantially a convex surface except a groove 26 defined in a middle portion 23 between two lateral portions 21. A first piece of sandpaper 28 is attached to the floor of the groove 26. Made on one of the lateral portions 21 of the bottom 20 is a mark 22 such as “STEP 2.” The mark 22 may be written, painted, embossment or intaglio. The mark...

Abstract

A grinder includes a first side, a second side, a first piece of sandpaper attached to the first side and a second piece of sandpaper attached to the second side. The second piece of sandpaper is finer than the first piece of sandpaper. The first piece of sandpaper is used to grind and turn a tip of a rubber strip of a windshield wiper from broken to flat quickly. The second piece of sandpaper is used to make the tip of the rubber strip of the windshield wiper smooth. A first mark is provided on the first side for indicating a first step of a grinding process. A second mark is provided on the second side for indicating a second step of the grinding process.

Description

BACKGROUND OF INVENTION [0001] 1. Field of Invention [0002] The present invention relates to windshield wipers and, more particularly, to a grinder for windshield wipers. [0003] 2. Related Prior Art [0004] Windshield wipers are important equipment for vehicles. The quality of windshield wipers determines whether rain can completely be wiped from the windshields of the vehicles. Whether rain can completely be wiped from the windshields determines whether drivers can have clear view through the windshields. Clear view is very important for the safety of the drivers' safety and / or pedestrians who are nearby. [0005] A typical windshield wiper includes a rubber strip for wiping rain from a windshield and a frame for carrying the rubber strip. When newly installed, windshield wipers generally can wipe rain from windshields completely. However, after used for some time, the rubber strips of the windshield wipers will inevitably be hardened and fail to wipe rain from the windshields complet...
