Description

  The present invention relates to a corner pole that protrudes from a corner portion of a vehicle and is visible from a driver of the corner portion.

  In order to ensure that a driver can visually recognize a corner (corner) of a vehicle, a corner pole is widely disposed at a corner of a front bumper. As such a corner pole, in order to maintain visibility even at night, for example, an acrylic resin material formed in a rod shape is projected at a desired position of the front bumper, and a light source such as an LED is installed on the base end side of the acrylic resin material Has been provided.

  That is, the light emitted from the light source emits light while being guided in the longitudinal direction of the acrylic resin material, so that the driver can see the corner portion of the vehicle well at night. However, there is also provided an improved design of the corner pole at the time of light emission by diffusing the light guided by forming a slit on the outer peripheral surface at the tip of the corner pole. In addition, since this prior art does not relate to the literature known invention, there is no prior art document information to be described.

  However, in the above conventional corner pole, although the design is improved by diffusing light by the slit at the tip, the light emission form by the diffusion is limited to a monotonous one (for example, light emission in an annular shape), It has been difficult to achieve a design that matches the user's preferences. In addition, since the acrylic resin material is inexpensive and has a predetermined elasticity, it is preferable as a material of a corner pole that requires impact resistance. On the outer peripheral surface of the acrylic resin material, a user's preference is provided. There is also a problem that it is difficult to create a complicated character shape that matches, and to diffuse and emit light in the character shape.

  The present invention has been made in view of such circumstances, and a corner pole that can maintain impact resistance and can diffuse light well in a predetermined character shape at the tip portion to further improve designability. It is to provide.

  According to the first aspect of the present invention, the light emitted from the light source on the proximal end side is guided to the distal end side in a corner pole that is projected at the corner portion of the vehicle and is visually recognized by the driver of the corner portion. A predetermined character that is made of a rod-shaped light guide having a predetermined elasticity and a hard light-transmitting material attached to the tip of the light guide and can diffuse the light guided by the light guide And a diffusion portion having a shape inside.

  According to a second aspect of the present invention, in the corner pole according to the first aspect, the character shape of the diffusion portion is three-dimensionally formed by laser processing.

  According to a third aspect of the present invention, in the corner pole according to the first or second aspect, a reflecting plate capable of reflecting light guided by the light guide to the base end side is provided at a distal end side of the diffusing portion. It is attached.

  According to the first aspect of the present invention, since the light guide is made of a rod-like material having a predetermined elasticity (for example, an acrylic resin material), the impact resistance can be maintained and a hard light-transmitting material (such as a glass body) is maintained. A diffusion part made of is attached to the tip of the light guide, and a predetermined character shape can be built inside the diffusion part to diffuse light well, so that the design of the corner pole can be further improved .

  According to the second aspect of the present invention, since the character shape of the diffusion portion is three-dimensionally formed by laser processing, a complicated character shape that matches the user's taste can be easily formed.

  According to the invention of claim 3, since the reflecting plate capable of reflecting the light guided by the light guide to the base end side is attached to the distal end side of the diffusing portion, the light guided by the light guide and The light reflected by the reflecting plate passes through the diffusion portion, and the light can be diffused more strongly in the character shape inside the diffusion portion. Therefore, the design property can be further improved.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The corner pole according to the present embodiment projects from the corner portion of the front bumper of the vehicle, and is for visual recognition from the driver of the corner portion. As shown in FIG. 1 and FIG. As an acrylic resin material 1, a mounting portion 2 made of a resin molded product, a diffusion portion 4, a reflecting plate 5, and an LED 6 as a light source.

  The mounting portion 2 includes a pole mounting portion 2a and a vehicle fixing portion 2b. The vehicle fixing portion 2b is fixed to the front bumper B of the vehicle by mounting screws N, and the pole mounting portion 2a is fixed to the vehicle fixing portion 2b ( Specifically, it is configured such that a nut M can be screwed onto and fixed to a male thread protruding from the pole mounting portion 2a. Further, the LED 6 as a light source is accommodated in the pole mounting portion 2a, and the base end of the acrylic resin material 1 is in contact with the light emitting surface of the LED 6 (upper surface in the figure).

  The acrylic resin material 1 is composed of a solid rod-shaped member, and can guide the light emitted from the LED 6 on the base end 1a side to the front end 1b side, and the acrylic resin material 1 is because of its material. It has a predetermined elasticity and is excellent in impact resistance. In addition, the dimension of the longitudinal direction of the acrylic resin material 1 can be made into the arbitrary dimension which a driver | operator can visually recognize from the driver's seat of a vehicle in the state fixed to the front bumper B.

  The diffusion part 4 is made of a substantially cubic glass body as a hard light-transmitting material, and is attached to the tip 1 b of the acrylic resin material 1 via the holder 3. More specifically, as shown in FIG. 3, a convex portion 1ba protruding upward in the drawing is integrally formed at the tip 1b of the acrylic resin material 1, and the acrylic resin material 1 including the convex portion 1ba is formed. Both the front end 1b side and the bottom surface (lower surface) side of the diffusing portion 4 are held by the holder 3, and these are integrated. The holder 3 is substantially sealed so that the light guided by the acrylic resin material 1 can reach the diffusion portion 4 side without leaking to the surroundings.

  Furthermore, a character shape 4a (in the present embodiment, the letter “A” of the alphabet is used as a character shape for the sake of convenience) that can diffuse the light guided by the acrylic resin material 1 is formed inside the diffusion portion 4. Has been. The character shape 4a is three-dimensionally formed by laser processing. As a result, in addition to the character “A” as in the present embodiment, a complicated character shape (animal such as a bear) that matches the user's taste. Can be easily formed.

  Specifically, as shown in FIG. 4, a highly transparent hard block glass body (diffusion part 4) is irradiated with a high heat generation laser from three directions (lasers L1, L2 and L3 in the figure). A predetermined character shape is “stipulated” by causing a thermal change at the three intersections P. In other words, light can be diffused by the character by making minute scratches due to thermal changes at predetermined positions on the glass body and expressing the aggregate of such scratches as a modeled object.

  Further, by moving the laser beam in accordance with an operation programmed by computer control to form a character shape, it is possible to form a character shape that matches the user's taste more reliably and easily. In addition, it is preferable to use optical glass from which lead has been removed in the process of manufacturing artificial crystal glass as the glass body. In this case, it is possible to give a high-class feeling and further improve the design.

  The reflecting plate 5 is attached to the distal end side (upper end side in the figure) of the diffusing portion 4 and can reflect the light guided by the acrylic resin material 1 to the proximal end side (lower side in the figure). Is constituted by a reflecting member formed in an upward convex arc shape. The reflector 5 forms a corner pole tip. Thereby, the light guided by the acrylic resin material 1 (light traveling upward in the drawing) and the light reflected by the reflecting plate 5 (light traveling downward in the drawing) pass through the diffusion portion 4 and diffuse. The light can be diffused more strongly in the character shape 4 a inside the portion 4.

  With the above configuration, when the LED 6 is turned on, the light is received on the base end 1a side of the acrylic resin material 1 and can be emitted while being guided in the longitudinal direction, and light reaching the front end 1b of the acrylic resin material 1 is emitted. The light passes through the diffusing unit 4 and light is diffused by the character shape 4a during the passage, so that the light is emitted more strongly. That is, since the character shape 4a emits light stronger than the ambient light and the character is emphasized, the visibility of the corner portion of the vehicle at night can be improved and the design can be improved. As described, the light that has passed through the diffusing unit 4 is reflected by the reflecting plate 5 and causes the character shape 4a to emit light more strongly.

  According to this embodiment, a light guide body (acrylic resin material) that requires impact resistance and a diffusion part (glass body as a hard translucent material) that can form a character shape inside with high accuracy are separate members. Since these are integrally assembled into a corner pole, each member can be manufactured by an appropriate manufacturing method, and impact resistance and design can be simultaneously achieved. Moreover, since the diffusing part 4 is connected to the acrylic resin 1 by screwing the holder 3, it is easy to replace the diffusing part 4 with another character by removing the screw.

  As mentioned above, although this embodiment was described, this invention is not limited to this, For example, it replaces with the acrylic resin material 1, consists of a rod-shaped member which has predetermined elasticity, and is from the light source of a base end side. It is good also as another material which can guide the irradiated light to the front end side. However, the manufacturing cost can be reduced by using a relatively inexpensive acrylic resin material as in this embodiment.

  In addition to the substantially cubic shape as in this embodiment, the diffusing portion can form a predetermined character inside, and can diffuse light in its shape. It may be a thing. Further, the character shape formed inside the diffusion portion can be any shape, and for example, the character shape may differ depending on the viewing angle. In addition, it may replace with LED6 of this embodiment, and it is good also as another light source (for example, lamp etc.) which can irradiate light to the acrylic resin material (light guide) side. Furthermore, as long as the diffusing portion is a hard translucent material capable of forming a character shape, another material may be used instead of the glass body.

  The light emitted from the light source on the proximal end side can be guided to the distal end side, and is composed of a rod-shaped light guide body having a predetermined elasticity and a hard translucent material attached to the distal end of the light guide body. If the corner pole is provided with a diffuser having a predetermined character shape inside that can diffuse the light guided by the light guide, a corner pole having a different appearance shape or other functions or designs are added. It can also be applied to other things.
