JPH0714579Y2 - Light guide member for keyhole illumination - Google Patents

Description

TECHNICAL FIELD The present invention relates to a light guide member, and more particularly to a light guide member mounted between an escutcheon and a cylinder lock.

2. Description of the Related Art For example, as disclosed in Japanese Utility Model Laid-Open No. 61-71763, a door outside handle structure having an illumination ring inserted into a protrusion provided on a handle cover of an automobile is known. This structure is provided with a stopper that is locked to the handle cover and prevents the illumination ring from falling off.

Further, Japanese Utility Model Laid-Open No. 61-103249 discloses an out-handle keyhole lighting device in which a cylinder lock and a light-transmitting ring on the front surface of the cylinder lock are attached to an out-handle case that pivotally supports the out-handle. ing. In this illuminating device, a shaft cylinder having a front opening into which an inner cylinder of a cylinder lock is fitted, a first annular recessed groove which is opened in a front surface of the shaft cylinder and into which a through-hole ring is fitted, is provided in an outer handle case. A second annular groove that is open to the front surface of the annular groove and into which the outer cap is fitted is provided. An inner cylinder that is inserted into the shaft cylinder by bending and locking the locking claws provided in the outer cap into a plurality of locking holes provided in the bottom surface of the second annular groove, and is inserted into the first annular groove. The transparent ring is fixed to the case via the outer cap.

Further, Japanese Utility Model Laid-Open No. 1-70957 discloses a structure in which a spacer is integrally formed with an end cover arranged between a door panel and a handle escutcheon, and the spacer is arranged between a light guide member and a handle escutcheon. It is shown.

Problems to be Solved by the Invention In the above-mentioned conventional structure, the holder 1 shown in FIG. 6 is generally attached to the cylindrical portion formed on the handle escutcheon. The light guide member 2 shown in FIG. 5 is attached to the holder 1,
After that, the cylinder lock is attached to the cylindrical portion. The light guide member 2 is used for illuminating the keyhole, but is formed in the same shape as the light guide member 2 shown in FIG. 5 by using a non-light guide material for an automobile that does not illuminate the keyhole. A spacer is attached to keep the appearance of the handle. As described above, conventionally, three parts, that is, the holder 1, the light guide member 2, and the spacer formed of the non-light guide material are required. When the light guide member 2 is directly attached to the cylindrical portion of the handle escutcheon without using the holder 1, a sufficient amount of light cannot be obtained around the keyhole, and even if the keyhole lighting device is turned on, the keyhole illuminator is sufficiently turned on. There was no illumination around the hole.

An object of the present invention is to provide a keyhole illuminating light guide member which has a small number of parts and which can illuminate a keyhole with a sufficient amount of light.

Means for Solving the Problems The light guide member for keyhole illumination according to the present invention comprises a ring portion and a mounting portion which are integrally formed of a light guide material. An annular protrusion that is fitted into the opening of the escutcheon to which the cylinder lock is attached is integrally formed with the ring portion. The light guide material that constitutes the light guide member for keyhole illumination contains a colorant.

Action Since the keyhole illuminating light guide member having the annular protrusion can be integrally formed, the number of parts can be reduced and the number of steps for assembling the door handle can be reduced. In addition, the annular projection increases the amount of light around the keyhole, thereby enabling sufficient illumination. Further, by mixing a colorant into the light guiding material, it is possible to attach the colored keyhole illuminating light guiding member to an automobile without a keyhole illuminating device.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 1, a keyhole illuminating light guide member 10 according to the present invention comprises a ring portion 11 and a mounting portion 12 which are integrally formed of a light guide material such as acrylic resin or polycarbonate resin. An annular projection 15 fitted into the opening 14 of the escutcheon 13 shown in FIGS. 2 to 4 to which a cylinder lock (not shown) is mounted is integrally formed with the ring portion 11. The light guide material forming the key hole illuminating light guide member 10 is mixed with a colorant such as a pigment to the extent that the light guide property is not significantly impaired.

At the time of mounting, after the light emitting diode (not shown) is mounted in the groove 18 of the mounting portion 12, the screw 17 (third screw) is inserted in the hole 16 shown in FIG.
(Fig.) Insert the escutcheon 13 into the keyhole lighting light guide member.
Can be installed 10.

In the above configuration, since the keyhole illuminating light guide member 10 having the annular protrusion 15 can be integrally formed, the number of parts can be reduced and the number of steps for assembling the door handle can be reduced. In addition, the annular protrusion 15 increases the amount of light around the keyhole, thereby enabling sufficient illumination. Furthermore, by mixing a colorant into the light guiding material, it is possible to attach the colored keyhole illuminating light guide member 10 to an automobile without a keyhole illuminating device.

EFFECTS OF THE INVENTION As described above, according to the present invention, it is possible to obtain a light guide member for illuminating a keyhole, which is easy to assemble and which can illuminate the periphery of the keyhole with a sufficient light quantity. Further, since the light guide member for illuminating the keyhole can be integrally formed, an object such as an escutcheon incorporating a cylinder lock can be thinly formed.
