Description

SHIELDING ASSEMBLY FOR CAR WINDOW

Technical Field

[1] The present invention relates, in general, to equipment which is mounted to a car window to block the sun or protect against flies, mosquitoes, and other harmful insects and, more particularly, to a shielding assembly for car windows, which includes a main support frame comprising a tube filled with air and having a shape corresponding to the shape of the inner surface of a window frame, a shielding unit arranged inside the main support frame, and a holding means connecting the main support frame to the window frame, thus allowing the main support frame, which is light and has high contact ability, to be firmly secured to the window frame, and which is provided with a nozzle used to inject a filler into the main support frame, so that air can be discharged through the nozzle when not in use, thus being easy to store, and which has a detachable attaching means on the shielding unit, thus being capable of attaching or detaching the entire portion or a predetermined portion of the shielding unit, and which further includes a subsidiary support frame to divide the shielding unit into several sections, thus realizing high durability and affording a variety of designs. Background Art

[2] Generally, a sun screen member is attached to a car window using suction plates.

However, the sun screen member is problematic in that it is incapable of completely blocking the sun because there are various shapes of car windows. It is difficult in practice to manufacture the sun screen member to be suitable for the specific shape of a window in order to solve this problem.

[3] Further, when the window is lowered, the sun screen member must be detached from and then attached to the window, thus inconveniencing a user.

[4] In order to solve the problem, Korean U.M. Laid-Open Publication No. 93-6508, which is entitled "Sun Screen For Cars", has been proposed. The sun screen is mounted to the inner surface of a car window, and is opened or closed in the fashion of a curtain as desired, thus allowing a user to see through the sun screen. The sun screen is advantageous in that it is convenient to use (it is easily opened or closed). When a car is driven in the state in which the window is slightly lowered, the curtain-type sun screen flutters in the wind, thus hindering driving. Further, the curtain-type sun screen slides forwards and backwards when the car makes a sudden start or stop, so that the sun blocking function of the sun screen is not efficiently performed.

[5] Meanwhile, in order to prevent flies, mosquitoes, and other harmful insects from entering a car, an insect screen is required. In order to mount the insect screen to a car window, Korean U.M. Publication No. 20-1990-0011000, which is entitled "Insect Screen For Cars", has been proposed.

[6] According to the cited document, the insect screen includes left and right screen parts which are coupled to each other to be foldable along a hinge. Fitting grooves are formed in the lower portions of the left and right screen parts. Wing pieces are coupled to the side ends and upper ends of the left and right screen parts. A locking hook and a locking rib are attached to the lower ends of the left and right screen parts, and a handle is provided at a predetermined position on the left screen part. In order to secure the insect screen to a car door, the wing pieces are fitted into fitting grooves in a window frame. However, the conventional insect screen is problematic in that it is not firmly secured to the window frame, so that the insect screen may be undesirably removed from the window frame when a car drives at high speeds.

[7] In order to easily attach or detach a screen to or from a window frame of a car without an additional locking means, Japanese Patent Laid-Open Publication No. 2001-18645 is disclosed, which is entitled "Air-Filled-Type Screen For Cars". According to the cited document, the screen includes a frame comprising an envelope which is filled with air, and a screen part which is installed in the frame, with an air charging and exhausting member installed in the envelope. The screen is in close contact with the window frame to be secured thereto, so that it is easy to attach or detach the screen to or from the window frame, and thus the screen can be used while a car is parked or stopped. However, the screen is problematic in that it may be undesirably removed from the window frame when the car is driving at high speeds, so that it is impossible to use the screen.
