Sideview mirror for vehicles
First Claim
1. A sideview mirror for a vehicle, comprising:
- a housing including an inner tubular member and an outer tubular member, the housing having a main pipe and a branching pipe extending laterally from a center portion of the main pipe;
an object lens system arranged in a rearward portion of the main pipe, the object lens system having at least one lens;
an eye lens system arranged in the branching pipe, the eye lens system having at least one lens;
blowing means arranged in a forward portion of the main pipe, wherein the blowing means includes;
a cover plate attached to a front end of the main pipe and provided with a plurality of air apertures;
a movable plate slidably arranged inwardly from the cover plate and provided with a plurality of air apertures selectively aligning with the air apertures of the cover plate;
resilient means for urging the movable plate to slide in a direction so as to prevent the air apertures of the movable plate from aligning with the air apertures of the cover plate;
driving means for sliding the movable plate against an urging force of the resilient means for aligning the air apertures of the movable plate with the air apertures of the cover plate;
air guiding means for guiding air passing through the aligned air apertures to both a surface of an outermost lens of the object lens system and a surface of an outermost lens of the eye lens system, the air guiding means having an inlet for receiving the air; and
a heater disposed near the inlet of the air guiding means and adapted to heat the air coming into the air guiding means; and
reflecting means arranged in the center portion of the main pipe at a predetermined angle with respect to an optical axis of the eye lens system.

Abstract
A sideview mirror includes a housing having an inner tubular member and an outer tubular member. The housing has a main pipe and a branching pipe extending laterally from a center portion of the main pipe. An object lens system is arranged in a rearward portion of the main pipe, and an eye lens system is arranged in the branching pipe. A blowing device is provided in the forward portion of the main pipe. The main pipe further includes a reflecting member in its center portion to form a predetermined angle with respect to an optical axis of the eye lens system. The blowing device includes a cover plate which has through holes as air apertures and a movable plate having air apertures. The air apertures of the cover plate and the movable plate may be selectively aligned to allow air to enter the mirror. An air guider is provided to guide the entering air to the object lens system and the eye lens system. A tension spring urges the movable plate to a position which prevents air flow through the air apertures, but a driver is provided to slide the movable plate against the resilient force of the spring, thereby allowing air to flow through the apertures when they become aligned. A heater is also provided in the main pipe to heat the air coming into the air guider.
