Description

  The present invention relates to a decorative article whose decoration effect is enhanced by light.

Various decorative products that produce an effect of light for decorative purposes have been proposed (see, for example, Patent Document 1).
As shown in FIG. 7, the decorative article 60 includes a dotted light source 61 attached to a base (not shown) and a polarizing member 62 disposed on the opposite side of the base with the light source 61 interposed therebetween. Yes. The polarizing member 62 transmits the light from the light source 61. The polarizing member 62 refracts and reflects light in the process of transmission so that the light is linearly extended in the direction intersecting the thickness direction of the polarizing member 62 (vertical direction in FIG. 7). To do. Therefore, when the light source 61 is turned on, the linear light 63 that cannot be seen when the light source 61 is turned off becomes visible.

Japanese Patent No. 561397

  However, when the light emitted from the light source 61 is directly polarized by the polarizing member 62 as described above, the width of the obtained linear light 63 depends on the size of the light source 61. The amount of light transmitted through the polarizing member 62 is large, and the light 63 obtained by polarized light becomes wide (the dimension in the left-right direction in FIG. 7), and the decoration effect by the light 63 is impaired.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a decorative article that can express linear light with a narrower width and further enhance the decorative effect. .

  A decorative article that solves the above problems is composed of a light source and a rod-like body arranged with its end facing the light source, and a recess is provided in the middle in the length direction. A part of the incident light is reflected by the inner wall surface of the recess and is emitted, and a part of the light emitted from the light guide is transmitted, and the light is polarized in the transmission process. A polarizing member, and the polarizing member polarizes the light so as to form a linear shape extending in a direction intersecting a thickness direction of the polarizing member.

  According to said structure, when a light source emits light, the light will inject into a light guide from the edge part facing the light source, and will propagate through a light guide. A part of this light hits the inner wall surface of the recess and is reflected and emitted from the light guide. Part of the emitted light is transmitted through the polarizing member. In this transmission process, the light is polarized so as to form a linear shape extending in a direction crossing the thickness direction of the polarizing member.

  In this way, the concave portion functions as a pseudo point light source smaller than the light source. Therefore, the linear light after polarization can be made narrower than the case where the light emitted from the light source without using the light guide is directly polarized by the polarizing member.

In the decorative product, it is preferable that the concave portion is formed by a conical hole.
According to said structure, since a weight-shaped recessed part refracts | refracts | reflects light on an inner wall surface to a top part, light gathers at a top part and a top part becomes brighter than the other part (remaining part). Furthermore, since the concave portion has a weight shape, the width of the top portion is narrow, and a more pseudo point light source is configured. And the light polarized after being emitted from the light guide through the top is narrower than the light polarized after being emitted from the light guide through the remaining part, and with high brightness (illuminance) It becomes linear. Therefore, more delicate and clear linear light is expressed by the former light.

In the decorative article, it is preferable that the inner wall surface of the recess is formed to be a rough surface.
According to said structure, light is irregularly reflected in the inner wall face of the cone-shaped hole formed in the rough surface. Therefore, it is possible to make the linear light after being polarized by the polarizing member and its surroundings brighter than when the inner wall surface is formed on a mirror surface.

In the decorative article, it is preferable that the polarizing member is made of a woven fabric woven from twines.
Here, the leno weave is generally a coarse woven fabric in which two warps are twisted and woven with wefts.

  According to said structure, the light radiate | emitted from the light guide strikes a weft and is reflected or refracted | refracted when permeate | transmitting a polarizing member. As a result, it is considered that the light is linearly polarized extending in the direction along the weft arrangement direction.

  In the decorative article, the light guide is disposed on a base portion, and at least a peripheral portion of the light guide body is provided with a reflection portion that reflects light emitted from the light guide body. It is preferable that

  According to said structure, a part of light radiate | emitted from the light guide is reflected (diffused) in various directions by the reflection part provided in the peripheral part of the light guide at least among bases. Therefore, it is suppressed that the external shape of a light guide is visible through a polarizing member.

  According to the above-described decorative article, it is possible to express linear light with a narrower width and further enhance the decorative effect.

Explanatory drawing which shows the woven structure of the polarizing member in a modification. It is a figure which shows a prior art and is a partial rear view which shows the ornament at the time of light source lighting.

Hereinafter, an embodiment embodied in a decorative article incorporated in an instrument panel of a vehicle will be described with reference to FIGS.
In the following description, it is assumed that the traveling direction (forward direction) of the vehicle is the front, the backward direction is the rear, and the height direction is the vertical direction. Moreover, about a vehicle width direction (left-right direction), a direction is prescribed | regulated on the basis of the case where a vehicle is seen from back.

  Fig.1 (a) has shown the side cross section of the instrument panel 10 of the state arrange | positioned in the front part of a compartment and the ornament 20 of this embodiment assembled | attached. An assembly recess 11 is provided at the rear portion of the instrument panel 10. The assembly recess 11 is constituted by a space surrounded by a peripheral wall portion 12 and a front wall portion 13 that form a rectangular tube shape.

  FIG. 3 shows a state in which a part of the decorative article 20 is viewed from the rear. However, in FIG. 3, the design panel 41 is not shown. The illustration of the design panel 41 is omitted in FIGS. 4 and 5.

As shown in FIGS. 1A, 1 </ b> B, and 3, the decorative article 20 includes a base, a pair of light sources 21 and 22, a light guide 23, a polarizing member 35, and a design panel 41.
The base is a portion to which the light sources 21 and 22 and the light guide 23 are attached. In the present embodiment, the front wall 13 of the assembly recess 11 is used as the base.

  The pair of light sources 21, 22 are arranged at locations separated from each other in the vehicle width direction on the front wall portion 13, and are fixed to the front wall portion 13. Each of the light sources 21 and 22 is configured by a light emitting diode (LED) that is a semiconductor light source, and emits light toward the opposed light sources 22 and 21. In the present embodiment, light sources 21 and 22 that emit light of the same color are used.

  The two light sources 21 and 22 are used in order to secure the light quantity. That is, the light is guided to the recesses 26 provided at a plurality of positions spaced apart in the length direction of the light guide 23 without any shortage.

  The light guide 23 is made of a transparent resin material, here a rod-shaped body made of PMMA (polymethyl methacrylate) which is one form of acrylic resin. In the present embodiment, a light guide 23 having a square cross section with a side of 5 mm is used. The light guide 23 is disposed between the light sources 21 and 22 so as to extend in the vehicle width direction. A pair of end portions 25 in the length direction (vehicle width direction) of the light guide 23 are opposed to the light sources 21 and 22 at locations close to the light sources 21 and 22. The light guide 23 guides (guides) the light emitted from the light sources 21 and 22 and incident from the end 25 toward the opposite end 25 using internal reflection.

  Concave portions 26 are provided at a plurality of locations that are intermediate portions in the length direction (vehicle width direction) of the light guide 23 and are spaced apart from each other in the same direction. Each concave portion 26 is opened on the front surface 24 (see FIG. 1B) which is a surface facing the front wall portion 13 among the outer surface of the light guide 23. Each concave portion 26 is configured by a conical hole whose diameter decreases toward the polarizing member 35. In the present embodiment, each recess 26 is formed such that the diameter at the opening 31 is 3 mm and the depth (distance from the front surface 24 to the top 28) is 3 mm. The top portion 28 has a shape narrower than the light emitting surfaces of the light sources 21 and 22.

  Moreover, in this embodiment, each recessed part 26 is formed in the rough surface by cutting. Instead of cutting, the recess 26 may be formed together when the light guide 23 is formed. The light guide 23 having the above-described configuration emits a part of the light incident from the end portion 25 and internally reflected in the light guide 23 by the inner wall surface 27 of the recess 26.

In addition, the transparency here includes colored transparency as well as colorless transparency.
The polarizing member 35 transmits a part of the light emitted from the light guide 23, and in the transmission process, transmits the light in a direction intersecting the thickness direction of the polarizing member 35 (in the vertical direction in the present embodiment). It is for polarizing so as to form an extending line.

  As shown in FIG. 2, the polarizing member 35 is composed of a woven fabric entangled. Here, the leno weave is generally a coarse woven fabric in which two warp yarns 36 and 37 are twisted and weaved with a substantially straight weft 38 and transmits light. obtain. The interval between the adjacent wefts 38 is set to be narrower than the interval between the twisted warps 36 and 37 and the adjacent warps 36 and 37. Such a setting is made for the purpose of obtaining a large thread surface area for deflection and reflection of light and for obtaining a sufficient degree of opening for light to pass through. At least one of the warp yarns 36, 37 and the weft yarn 38 may be a filament yarn in the form of a monofilament, or may be a twisted yarn or a wrap yarn. At least one of the warps 36, 37 and the weft 38 may be made of synthetic fiber or artificial inorganic fiber, or may be made of natural fiber such as mineral fiber. The warp yarns 36 and 37 and the weft yarn 38 may be transparent or dyed.

As shown in FIG. 1A, the polarizing member 35 is attached to the instrument panel 10 in a state where the polarizing member 35 is tensioned and covers the opening 14 of the assembly recess 11 from the rear.
The design panel 41 is formed in a thin plate shape by a colored transparent resin material as a whole, here a dark and smoke-like resin material. The design panel 41 includes a horizontal panel portion 42 that covers the upper surface of the instrument panel 10 from above, and a vertical panel portion 43 that covers the rear surface of the instrument panel 10 and the polarizing member 35 from the rear. The horizontal panel portion 42 and the vertical panel portion 43 are locked to the instrument panel 10 by locking means (not shown) such as claw fitting. A portion of the vertical panel portion 43 that is behind the polarizing member 35 is curved so as to swell rearward.

Next, the operation of the present embodiment configured as described above will be described separately when the light sources 21 and 22 are turned off and when they are turned on.
<When both light sources 21 and 22 are turned off>
At this time, light is not emitted from the light sources 21 and 22, as shown in FIGS. Accordingly, neither light is incident on the light guide 23 nor light is reflected on the inner wall surface 27 of the recess 26, and no light is emitted from the light guide 23.

  The design panel 41 makes the polarizing member 35 inside the assembly recess 11 difficult to see when the consent design panel 41 is viewed from the rear of the instrument panel 10. In addition, the light guide 23 and the light sources 21 and 22 are disposed in the assembly recess 11 and in front of the polarizing member 35, but the polarizing member 35 and the design panel 41 block these from being seen.

<When both light sources 21 and 22 are turned on>
At this time, as shown in FIGS. 1A, 1B, and 4, the light emitted from each of the light sources 21, 22 is incident on the light guide 23 from the end portion 25 facing the light sources 21, 22. The This light is guided in the light guide 23 while being internally reflected toward the opposite end 25. In this way, a part of the light reflected from the inner surface of the light guide 23 strikes the inner wall surface 27 of each recess 26 and is reflected and emitted from the light guide 23 to the rear or the like. Light from the light sources 21 and 22 is reflected by the inner wall surfaces 27 of the plurality of recesses 26 and emitted. Further, the light attenuates not a little by passing through the light guide 23. Therefore, the amount of light that is emitted from the light guide 23 after being reflected by the inner wall surface 27 for each recess 26 and applied to the polarizing member 35 is such that the light emitted from the light source does not pass through the light guide directly. Is less than in the case of conventional irradiation (the conventional technique corresponds to this).

  Part of the light emitted from the light guide 23 passes through the polarizing member 35. In this transmission process, the light is polarized so as to form a linear shape extending in a direction (vertical direction in FIG. 4) along the arrangement direction of the wefts 38 in the polarizing member 35 among the directions intersecting the thickness direction of the polarizing member 35. Is done. Such polarized light is considered to be caused by the light emitted from the light guide 23 being reflected or refracted by hitting the substantially linear weft 38 (see FIG. 2) when passing through the polarizing member 35. It is done.

  The linear light 45 and 46 after polarization shown in FIG. 4 is reflected and transmitted through the colored and transparent design panel 41 (see FIG. 1A). Therefore, a passenger looking at the instrument panel 10 from the rear can see a pattern of a plurality of linear lights 45 and 46.

  Thus, each recessed part 26 functions as a pseudo point light source smaller than the light sources 21 and 22. Therefore, the width of the linear light 45 and 46 after polarization (the horizontal dimension in FIG. 4) is the width when the light emitted from the light source is polarized by the polarizing member without using the light guide (prior art). Narrower than.

  In particular, in the present embodiment, as shown in FIGS. 1B and 4, each recess 26 is constituted by a conical hole. These conical recesses 26 refract light toward the top 28 while reflecting light by the inner wall surface 27. Therefore, in each concave portion 26, light gathers at the top portion 28, and the top portion 28 becomes brighter than other portions (hereinafter referred to as "remaining portion 29"). Furthermore, since each concave portion 26 has a conical shape, the width of each top portion 28 is narrow, and a more pseudo point light source is configured. The light 46 that has been collected at each top 28 and emitted from the light guide 23 and then polarized is narrower than the light 45 that has been polarized from the light guide 23 after being emitted from the light guide 23 through the remaining portion 29. It is linear with high brightness (illuminance) and overlaps the light 45. Both of the polarized lights 45 and 46 are widest at the center in the length direction (vertical direction in FIG. 4), and become narrower as they move away from the center.

  In the present embodiment, since the inner wall surface 27 of each recess 26 is formed to be a rough surface, light is irregularly reflected on the inner wall surface 27. Therefore, the linear lights 45 and 46 after being polarized by the polarizing member 35 and their surroundings become brighter than the inner wall surface 27 of each recess 26 is formed on a mirror surface.

  Here, if the light emitted from the light source without using the light guide is polarized by the polarizing member, the amount of light is large as described above, so the light source can be seen directly through the polarizing member, and the glare is felt. There is a risk of causing. In some cases, the polarizing member may not be viewed directly. Even if light is linearly polarized by the polarizing member, the decorative effect of the light is impaired.

  However, in this embodiment, as described above, the amount of light emitted from the light guide 23 and irradiated on the polarizing member 35 after being reflected by the inner wall surface 27 for each recess 26 does not pass through the light guide. The amount of light emitted from the light source is less than when the polarizing member is directly irradiated. For this reason, it is difficult for the occupant to see each recess 26. In addition, it is difficult for passengers to feel dazzling.

According to the embodiment described in detail above, the following effects can be obtained.
(1) The decorative article 20 includes light sources 21 and 22, a light guide body 23 provided with a recess 26, and a polarizing member 35. The recess 26 is caused to function as a pseudo light source smaller than the light sources 21 and 22. Then, a part of the light emitted from the light guide 23 after being reflected by the inner wall surface 27 of the recess 26 is polarized by the polarizing member 35 so as to form a linear shape extending in a direction intersecting the thickness direction. Yes. (FIG. 1 (a), (b), FIG. 4).

  Therefore, the linear light 45 and 46 after being polarized by the polarizing member 35 can be made narrower than the case where the light emitted from the light source is not directly polarized by the polarizing member without passing through the light guide. . The decorative effect can be further enhanced by the narrower linear lights 45 and 46.

  Further, by reducing the amount of light reflected for each recess 26, it is possible to make each recess 26 less visible and to prevent the passenger from feeling dazzling. Therefore, it becomes easy for the passenger to look directly at the polarizing member 35 and the linear lights 45 and 46. The decoration effect by the linear lights 45 and 46 can be sufficiently exhibited.

(2) The recessed part 26 is comprised by the weight-shaped (conical) hole (FIG.1 (b)).
Therefore, each concave portion 26 can collect light at the top portion 28 and make the top portion 28 brighter than the remaining portion 29. Light 46 collected after being emitted from the light guide 23 after being collected at each top portion 28 is narrower and higher in brightness than light 45 polarized after being emitted from the light guide 23 through the remaining portion 29. And can be superimposed on the light 45. Furthermore, reflection and condensing action can be obtained with respect to light irradiated to the concave portion 26 from various directions, and the top portion 28 can be further brightened. Therefore, it is possible to express a more delicate and clear linear light 46.

(3) The inner wall surface 27 (FIG. 1 (b)) of each recess 26 is formed into a rough surface.
Therefore, the linear light 45 and 46 (FIG. 4) after being polarized by the polarizing member 35 and the periphery thereof can be made brighter than the inner wall surface 27 of each recess 26 is formed on a mirror surface.

In addition, the inner wall surface 27 can be roughened by cutting the polarizing member 35 and providing the recess 26.
(4) The polarizing member 35 is constituted by a woven fabric entangled (FIG. 2).

  Therefore, the light emitted from the light guide 23 can be reflected or refracted by the wefts 38 and can be polarized into a linear shape extending in the direction along the arrangement direction of the wefts 38 (vertical direction in FIG. 4).

(5) The part which becomes the back of the polarizing member 35 in the vertical panel part 43 is curved so that it may swell to back (FIG. 1 (a)).
Therefore, by reflecting the linear light 45 and 46 after polarization on the vertical panel unit 43, it is possible to produce linear light that is curved according to the viewing angle.

  Furthermore, by curving as described above, the distance from the polarizing member 35 to the vertical panel unit 43 varies depending on the angle at which the vertical panel unit 43 is viewed. At the place farthest from the polarizing member 35 in the vertical panel section 43, the linear light 45, 46 after polarization is seen as a place further away from the vertical panel section 43 to enhance the sense of depth. be able to.

In addition, the said embodiment can also be implemented as a modification which changed this as follows.
<About the light sources 21 and 22>
In the case where light can be guided to the recesses 26 provided at a plurality of locations separated in the length direction of the light guide 23 without being insufficient, one of the pair of light sources 21 and 22 is omitted. May be.

  -As a pair of light sources 21 and 22, what emits light of a mutually different color may be used. In this case, the timing to turn off and the timing to turn on may be different between the light sources 21 and 22.

  When the amount of light emitted from the light sources 21 and 22 is increased, the visible region is expanded without being attenuated, and the length of the linear light 45 and 46 after polarization tends to increase. Therefore, the light amount may be adjusted continuously or stepwise by dimming the light sources 21 and 22. If it does in this way, the length of linear light 45 and 46 after polarization can be changed, and the decoration effect by light 45 and 46 can be heightened further.

-As light sources 21 and 22, LED is typical like the said embodiment, However, What differs from LED may be used.
<About the light guide 23>
-As the light guide 23, what has a cross-sectional shape different from a quadrangle may be used.

In the case of the light guide 23 having a square cross section, the dimension of one side of the cross section may be changed to a dimension different from that of the above embodiment.
A plurality of combinations of the light guide 23 and the light sources 21 and 22 may be used. FIG. 5 shows an example of two combinations. Two light guides 23 are arranged in parallel to each other. In this case, it is desirable that the recess 26 in one light guide 23 is provided at a location shifted in the length direction of the light guide 23 with respect to the recess 26 in the other light guide 23. In this way, the linear light 45 and 46 emitted from one light guide 23 and polarized, and the linear light 45 and 46 emitted from the other light guide 23 and polarized, Appearing alternately in the length direction of the two light guides 23, the fabric-like expression can be expressed by light, and the design effect is further enhanced.

-The light guide 23 may be arrange | positioned with the attitude | position extended in the direction different from a vehicle width direction.
-The recessed part 26 may be comprised by the hole which makes pyramid shape different from cone shape, for example, a pyramid shape. In addition, the concave portion 26 may be formed by a hole having a shape different from the weight shape, for example, a cylindrical shape. In order to make a pseudo point light source smaller than the light sources 21 and 22, the top of the recess 26 is formed in the case of a pyramidal hole, and the bottom of the light source 21 and 22 in the case of a cylindrical hole. Any shape that is narrower than the surface may be used.

When the shape of the hole is changed as described above, the light 45 and 46 after being polarized by the polarizing member 35 has a shape different from that of the above embodiment.
-In the instrument panel 10, a reflection part may be provided in the peripheral part of the light guide 23 at least. 1 (a) and 1 (b) shows an example in which the reflection portion 15 is provided on the front wall portion 13 and the peripheral wall portion 12 of the assembly recess 11. If it does in this way, the light radiate | emitted from the light guide 23 to the front or the direction close | similar to it may also be reflected by the reflection part 15, and a light quantity can be increased. As a result, it is possible to prevent the outer shape of the light guide 23 from being seen through the polarizing member 35.

As the reflection part 15, for example, one colored in white is preferably used. This is because white is easier to reflect in a diffused state than other colors.
In addition, the reflection part 15 may be provided only in the front wall part 13 among the assembly recessed parts 11 (it is not provided in the surrounding wall part 12). In this case, the reflecting portion 15 may be provided on the entire front wall portion 13 or only on the peripheral portion of the light guide 23.

  -The number of the recessed parts 26 in the light guide 23 may be changed into the number different from the said embodiment. Moreover, the dimension (the diameter in the opening part 31, the depth of the recessed part 26) of each recessed part 26 may be changed into the value different from the said embodiment.

  The light that has entered the light guide 23 through the end portion 25 attenuates as it moves away from the light sources 21 and 22 in the length direction of the light guide 23. Therefore, when conical recesses 26 are provided at a plurality of locations in the length direction of the light guide 23, the area of the inner wall surface 27 of the recesses 26 may be increased as the distance from the light sources 21 and 22 increases. This can be realized by increasing at least one of the diameter at the opening 31 of each inner wall surface 27 and the depth of the recess 26 as the distance from the light sources 21 and 22 increases. In this way, the amount of light reflected by the inner wall surface 27 of the recess 26 can be made comparable regardless of the distance from the light sources 21 and 22.

Even in the case where the recess 26 is configured by a hole having a shape different from the conical shape, the same setting as described above may be performed for the area of the inner wall surface.
<About the polarizing member 35>
The polarizing member 35 may be any member that polarizes part of the light emitted from the light guide 23 so as to form a linear shape extending in a direction intersecting the thickness direction of the polarizing member 35. As long as this condition is satisfied, the polarizing member 35 may be a woven fabric having a configuration different from that of the above embodiment or a material different from the woven fabric.

  As the corresponding woven fabric, for example, one described in Patent Document 1 may be used. As shown in FIG. 6, the woven fabric is composed of a warp layer 51, a weft layer 53, and a leash yarn 55. The warp layer 51 is composed of a plurality of warps 52 arranged in parallel to each other. The weft layer 53 is composed of a plurality of wefts 54 arranged in parallel to each other in a state orthogonal to the warp 52. The warp layer 51 and the weft layer 53 have a planar shape and are in contact with each other. The tangled yarn 55 is wound around the outside of the warp yarn 52 and the weft yarn 54 that do not face each other. The warp yarn 55 joins the warp layer 51 and the weft layer 53.

  When the woven fabric having the above configuration is used as the polarizing member 35, the light emitted from the light guide 23 is reflected or refracted by hitting at least one of the warp 52 and the weft 54 when passing through the polarizing member 35, and is linear. Polarized.

Moreover, as a raw material different from a woven fabric, the polarizing film which satisfy | fills said conditions may be used, for example.
A plurality of polarizing members 35 may be used in an overlapping manner. In this case, it is desirable that the superposition is performed in a state where the polarization directions are different from each other. In this way, the light emitted from the light guide 23 passes through the plurality of polarizing members 35 and intersects the thickness direction of the polarizing member 35, but forms a linear shape extending in a plurality of different directions. Polarized.

<About the distance between the light guide 23 and the polarizing member 35>
In the range where the amount of polarized light is large and visible, the length of the linear light 45 and 46 after polarization tends to increase as the light guide 23 and the polarizing member 35 move away from each other. However, the widths of the linear lights 45 and 46 hardly change depending on the distance between the light guide 23 and the polarizing member 35.

Therefore, it is desirable to set the distance between the light guide 23 and the polarizing member 35 so that the length of the linear light 45, 46 is obtained.
If the light guide 23 and the polarizing member 35 are too far away, the polarized light cannot be visually observed, and the linear lights 45 and 46 are shortened.

<About the design panel 41>
-Unlike the said embodiment, the vertical panel part 43 in the design panel 41 may be formed flat.

<Applicable target>
The above-described decorative product can be applied to vehicle interior products other than the instrument panel 10.
