Abstract

(57) [Summary] (Corrected) [Purpose] Glass window for vehicles that eliminates blind spots for drivers. [Structure] A Fresnel lens 3 having a field-of-view expansion function is attached to a windshield-attaching weatherstrip 2 along a part of the inside surface of a windowpane 1 in a vehicle.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle glass window, and more specifically, it has a wider field of view and a smaller blind spot than a normal vehicle glass window, and this blind spot elimination function can be obtained without special processing on the window glass. The present invention relates to a vehicle glass window.

[0002]

[Prior Art]

 In order to drive the vehicle safely, the driver's seat must have a sufficiently wide field of view in the front, rear, left, and right directions. For this reason, rearview mirrors and side mirrors are attached to the vehicle, and the blind spots from the driver's seat are minimized by securing the field of view through these mirrors.

However, in a large vehicle such as a dump truck, for example, the driver's seat is at a high position, so that the field of view of the vehicle in the lower front direction and the lower side direction is not always ensured. There are cases. For this reason, in addition to side mirrors, large vehicles of this type are often equipped with mirrors that can be used to check the front downward direction and side downward direction of the vehicle to ensure the necessary visibility from the driver's seat.

Since these mirrors are mounted so as to project from the vehicle body, they may be transformed into dangerous projections in some cases, and there are problems such as generation of wind noise and complicated mounting work. It was accompanied. As a solution to the above-mentioned inconveniences that may occur in mirrors, for example, Japanese Utility Model Laid-Open No. 63-155715 proposes a method of mounting a Fresnel lens having a function of expanding the visual field on a part of a window glass for a vehicle.

[0005]

[Problems to be solved by the device]

 Although the field of view in the driver's seat can be expanded by mounting such a Fresnel lens on the upper and lower sides of the vehicle window glass, the conventional Fresnel lens is attached to the window glass by post-processing or post-processing. There is a drawback that the cost is high.

[0006]

[Means for Solving the Problems]

 The present invention has been made in view of the above problems in the prior art, and is characterized in that a Fresnel lens is provided on a weather strip for attaching a window glass. That is, the present invention has a weather strip for attaching a vehicle window glass to a vehicle opening, and a Fresnel lens having a field of view expanding function is attached to the weather strip along a part of the inside surface of the window glass. It is an attached glass window for vehicles.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a mounting portion of a vehicle glass window showing an example of the present invention. 1 is a window glass such as a windshield of a vehicle, a side window or a rear window, 2 is a weather strip for attaching the window glass 1 to an opening portion of a vehicle body 4, and 3 is a side surface of the window glass 1 along a vehicle interior. Fresnel lens provided on the weather strip 2.

The Fresnel lens 3 is usually made of a transparent synthetic resin such as a transparent acrylic resin, vinyl chloride resin, or polycarbonate resin, and has a concave lens function capable of expanding the driver's visual field. At this time, in order to secure a more uniform visual field, it is preferable to devise the refractive index of the concave lens so as to increase downward.

In this case, the Fresnel lens 3 is preferably installed at the lower side of the window glass 1 in the vicinity of the weather strip 2, and a part of the lower side where the blind spot needs to be eliminated is appropriately selected. The Fresnel lens 3 is usually integrally formed on a selected portion of the weather strip 2 when the weather strip 2 is molded. However, it may be provided in a predetermined portion of the weather strip by post-processing. In order to ensure the safety and good visual field of the Fresnel lens, the Fresnel lens should be installed as close as possible to the inside surface of the window glass 1 in the vehicle.

[0010]

[Effect of the device]

 As described above, according to the present invention, since the Fresnel lens is not directly provided on the window glass but is attached to the weather strip, the Fresnel lens can be installed more easily and can be integrally formed at the time of forming the weather strip. If so, it can be manufactured at an advantageous cost. The glass window for a vehicle provided with the Fresnel lens as described above is suitable for the glass window for a vehicle, which can enlarge the field of view due to the lens effect, eliminate the blind spot, and contribute to safe driving.
