Description

  The present invention relates to a decoration device used for decoration of a vehicle interior, a home appliance, an audio device, and the like, for example.

  An illuminating device installed in the interior of an automobile or other vehicle has a role of illuminating the inside of the vehicle. However, in recent years, not only such an illumination function for simply illuminating a room, but also a decoration device having a decoration function for improving the aesthetics of the room, that is, decorating the room, has been used.

  For example, foot lighting under an instrument panel in an automobile or indirect lighting for a center cluster or pillar can be selected as a plurality of colorful colors and used as illumination.

  Moreover, as a part used for the interior of a motor vehicle, there are a real wood board used for presenting a wood grain pattern, a film printed with a wood grain pattern, and the like. These parts are used in the center cluster or steering wheel of an automobile, or as an instrument panel or door trim as an ornament.

  For example, in Patent Document 1, a real wood board is illuminated from the side by a plurality of LEDs (light-emitting diodes), and this light is allowed to pass through the wood board via a light guide so that a decorative effect based on the wood grain pattern of the wood board is obtained. And a light emitting decoration device that can obtain a decoration effect even in the absence of external illumination, for example, at night.

Patent Document 2 discloses an illumination system in which an electroluminescence (EL) panel is disposed between a base material and a fabric so that light from the electroluminescence panel is supplied through the fabric. ing.

  However, since the light emitting decoration device described in Patent Document 1 uses an LED as a light source, when the light emitting decoration device is used as, for example, an automobile interior part, the thickness of the entire interior part becomes considerably large. For this reason, assuming the case where these interior parts are attached to the interior of an automobile, for example, this interior part may not be applied to an attachment structure provided in advance in the room. In addition, when such interior parts are used for a door trim or a headliner, the space between these door trims and the vehicle outer plate is very small, which may make it difficult to install in the interior of an automobile. is there. Furthermore, since the light emitting decoration device of Patent Document 1 emits light by arranging LEDs on the side of the wooden board, light emission unevenness occurs, and when the wooden board has a relatively large area, light from the side is emitted. May not reach the vicinity of the center of the wooden board and may not function as a decoration device.

  On the other hand, when the lighting system described in Patent Document 2 is turned on, light passes through the fabric and serves as a decoration device, but when the lighting system is turned off, the user simply sees the fabric. Fabrics are fabrics such as woven fabrics and knitted fabrics. Patterns can be applied to the fabrics themselves, but the surface conditions of the fabrics, such as surface roughness, are inherent to the fabrics. There is a limit, and it cannot cause the aesthetics obtained when using other substrates such as wood boards.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the following drawings, the same members are denoted by the same reference numerals. In order to facilitate understanding, the scales of these drawings are appropriately changed.
FIG. 1 is an exploded perspective view of a decoration device according to an embodiment of the present invention. FIG. 2 is another exploded perspective view of the decoration device shown in FIG. Furthermore, FIG. 3 is a side view showing a state when the decoration device according to the embodiment of the present invention is assembled. In the assembled decoration device 100 shown in FIG. 3, members described later are joined to each other. At this time, the respective members are bonded to each other by an adhesive, or are connected by an appropriate fastener (not shown) such as a screw. The decorative device 100 shown in these drawings includes an electroluminescence panel 50. Therefore, by lighting the electroluminescence panel 50, it can also serve as a lighting device.

  The decoration device 100 can be used, for example, as an interior in an automobile. In this case, the decoration device 100 according to the present invention is used as a door trim panel, an instrument panel, a floor carpet, a floor mat, a trunk panel, a passenger seat, a head. Can be used in conjunction with liners, sun visors and rear decks. Naturally, the decoration device 100 according to the present invention can be used for other purposes, for example, in the walls, ceilings and floors of a house, as well as door knobs, handrails, various furniture, and housings for AV equipment. It is.

  As shown in FIGS. 1 to 3, a decoration device 100 according to the present invention includes a decorative veneer 20 and an electroluminescence panel 50 having an outer shape corresponding to the decorative veneer 20. As shown in the drawing, the electroluminescence panel 50 is disposed on the one surface 22 side of the decorative veneer 20.

  The decorative veneer 20 in the illustrated embodiment is a veneer. The veneer is formed by thinly cutting natural wood. In the present invention, a veneer having a variety of wood grain patterns, for example, a grain pattern, a mesh pattern, a bump pattern, a mackerel pattern, an onion pattern, a bird pattern pattern, etc. can be used as the decorative veneer 20. These projecting plates are formed thin enough to transmit light from the electroluminescence panel 50. In a preferred embodiment, the thickness of the veneer used as the veneer 20 can be in the range of about 0.08 mm to about 1.0 mm.

  Moreover, you may make it use the decorative film in which the specific pattern, for example, the above-mentioned wood grain pattern is printed, as the decorative veneer 20. In this case, the decorative film alone may be used as the decorative veneer 20, or the decorative film and an appropriate base material (not shown) on which the decorative film is attached may be combined into the decorative veneer 20. Furthermore, as a matter of course, a plastic panel on which a specific pattern is printed can be used as the decorative veneer 20.

  As is well known, the electroluminescent panel 50 is a substantially flat panel that can be formed in various sizes and shapes. In the present invention, since the electroluminescence panel 50 is adopted, even if the area of the decoration device 100 is relatively large, the light from the electroluminescence panel can be applied without causing uneven light emission. The single plate 20 can be transmitted evenly. In addition, as is well known, there are various emission colors of the electroluminescence panel, and the electroluminescence panel 50 having a specific emission color can be selected according to the application.

  The electroluminescent panel 50 is connected to an electronic circuit (not shown) including a controller (not shown) and a switch (not shown) associated with the electroluminescent panel 50. Since this controller is connected to, for example, a battery (not shown) installed in the automobile, the electroluminescence panel 50 can be turned on or off by operating a switch. The switch (not shown) is preferably a manual switch that can be easily operated by, for example, an automobile occupant. Alternatively, the electroluminescence panel 50 may be connected to an electronic control unit (not shown) installed in the automobile so that the electroluminescence panel 50 is controlled by the electronic control unit. Further, the electronic circuit or controller may include a timer circuit for controlling the lighting time of the electroluminescence panel 50 and / or a luminance level circuit for controlling the luminance of the electroluminescence panel 50.

  1 to 3, the other surface 21 of the decorative veneer 20 is covered with the transparent coating film 10. The thickness of the transparent coating film 10 is 100 μm to 1000 μm, more preferably 350 μm to 600 μm. As described above, when a veneer is used as the decorative veneer 20, the veneer 20 is relatively easy to be damaged due to the carelessness of the user because the thickness of the veneer is small. The decorative veneer 20 is protected by coating 20 with the transparent coating film 10, and therefore, the decorative veneer 20 can be prevented from being damaged. Instead of the transparent coating film 10, a plate material or a transparent film formed from a transparent plastic material having relatively high rigidity may be bonded.

  Further, as shown in FIGS. 1 to 3, a reinforcing portion 40 is disposed between the decorative veneer 20 and the electroluminescence panel 50. FIG. 4 is a perspective view of a reinforcing portion of the decoration device according to the present invention. As shown in FIG. 4, the reinforcing portion 40 used in the decoration device 100 of the present invention includes a plurality of elongated members 41 extending in the longitudinal direction of the decorative veneer 20 and a plurality of members extending in the transverse direction of the decorative veneer 20. It is composed of an elongated member 42. As can be seen from FIG. 4 and the like, these elongated members 41 and 42 cross each other. Moreover, since the height of these elongate members 41 and 42 is substantially equal, the reinforcement part 40 shown by drawing is a substantially lattice-shaped member. The reinforcing portion 40 plays a role of increasing the rigidity of the decoration device 100 as a whole, and the reinforcing portion 40 can be formed from any material, but it is preferable to form the reinforcing portion 40 from a plastic material from the viewpoint of weight reduction. The reinforcing portion 40 does not necessarily have a lattice shape. For example, only one of the elongated members 41 and 42 may be provided, or the elongated members may be provided concentrically or radially.

  In addition, as shown in FIG. 4, the reinforcing portion 40 is provided with a columnar portion 68. These columnar portions 68 provided on one side of the reinforcing portion 40 support the entire decoration device 100 and serve to attach the decoration device 100 itself to another member, for example, the interior of a car. For this reason, the columnar portion 68 is preferably formed from a material having relatively high rigidity. As shown in the drawing, the height of the columnar portion 68 is higher than that of the elongated member 41 in the longitudinal direction and the elongated member 42 in the transverse direction. These columnar portions 68 are arranged at positions suitable for appropriately supporting the entire decoration device 100, and the number of the columnar portions 68 may be changed according to the dimensions of the decoration device 100. That is, when the decoration device 100 has a relatively large area, the number of the columnar portions 68 is further increased, and when the decoration device 100 has a relatively small area, the number of the columnar portions 68 is further reduced. In addition, it is good also as a structure where the columnar part 68 is attached to the joining base material 30 mentioned later.

  As shown in FIG. 3, when the decorative device 100 is assembled, the tip of the columnar portion 68 protrudes through the opening 58 of the electroluminescence panel 50. The tip of the columnar portion 68 protruding from the opening 58 is formed so as to be engageable with a mounting portion (not shown) formed in advance in the interior of the automobile, for example. Therefore, by using the tip of the columnar portion 68 protruding from the opening 58, the entire decoration device 100 can be easily attached.

  In addition, although the reinforcement part 40 may be arrange | positioned at the other surface 52 side of the electroluminescence panel 50, in order to protect the electroluminescence panel 50 which is a light source from an external impact, the reinforcement part 40 is electroluminescence. It is preferable that the panel 50 is located on the one surface 51 side.

  Furthermore, as shown in FIG. 4, the joining base material 30 is joined to one side of the reinforcing portion 40. The joining base material 30 has an outer shape corresponding to the decorative veneer 20, and as shown in FIGS. 1 and 2, the one surface 22 of the decorative veneer 20 and the one surface 31 of the joining base material 30 are joined. Yes. The joining base material 30 is made of, for example, a milky white material. As the milky white material used to form the bonding substrate 30, a milky white plastic material such as polypropylene, polycarbonate, ABS, or acrylic is selected.

  In addition, the joining base material 30 is not necessarily formed from these milky white materials, and after the other non-milky white material is made substantially milky white by a specific method, the joining base material 30 is formed from the other materials. It may be. As a method for making a material that is not milky white substantially milky white, for example, a light diffusing material composed of fine particles is mixed in the transparent material. In such a case, light, that is, light from the electroluminescence panel 50 diffuses when passing through the bonding substrate 30. Therefore, for example, even when the electroluminescence panel 50 is locally damaged, for example, when the opening 58 is formed in the electroluminescence panel 50, unevenness in light emission is caused by diffusing light by the bonding base material 30. The light can be transmitted through the decorative veneer 20 in a state where the occurrence of the above is suppressed.

  Moreover, in other embodiment, the substantially milky white joining member 30 can also be simply formed by roughening the surface of the joining base material 30 which consists of transparent materials. In this case, the surface of the bonding base material 30 made of a transparent material may be roughened by shot blasting at a high speed, and the matte pattern is transferred from the mold to the bonding base material 30 made of a transparent material. It may be. Further, a light transmissive substrate made of a light transmissive material capable of diffusing light may be disposed on the decorative veneer 20 side of the bonding substrate 30 made of a transparent material. As a matter of course, it is also possible to simply form the bonding substrate 30 from such a light transmitting material. Also in such a case, the light from the electroluminescence panel 50 is diffused by the bonding member 30, thereby allowing the light to pass through the decorative veneer 20 in a state in which the occurrence of uneven light emission is suppressed. In addition, when the surface of the joining base material 30 is roughened and the joining base material 30 and the decorative veneer 20 are joined with an adhesive, the decorative unit of the joining base material 30 is used in order to make the adhesiveness more reliable. It is desirable that one surface 31 serving as an adhesive surface with the plate 20 is a smooth surface and the surface on the opposite one surface 32 side is roughened.

  Furthermore, the joining base material 30 may be formed from a transparent material of a predetermined color, or a transparent sheet of a predetermined color may be inserted between the decorative veneer 20 and the joining base material 30. Even in such a case, similarly, the light from the electroluminescence panel 50 is diffused inside the bonding base material 30, thereby transmitting the light to the decorative veneer 20 in a state in which the occurrence of uneven light emission is suppressed. It is done. In particular, when the bonding base material 30 is formed from a transparent material of a predetermined color and when a transparent sheet of a predetermined color is used, light having a color different from the original light from the electroluminescence panel 50 is applied. It is also allowed to pass through the veneer 20, thereby obtaining a new decoration effect. Moreover, when using the transparent sheet of a predetermined color, for example, by lowering the light transmittance of the peripheral part of the transparent sheet from the central part, it is possible to produce an effect that the brightness gradually decreases from the center toward the peripheral part.

  Providing the bonding substrate 30 is particularly advantageous when the reinforcing portion 40 is disposed between the electroluminescence panel 50 and the bonding substrate 30. In such a case, the light from the electroluminescence panel 50 passes through the elongated members 41 and 42 themselves and reaches the bonding substrate 30 or a gap between the adjacent elongated members 41 and 42 is formed. It passes through and reaches the bonding substrate 30. That is, when the light from the electroluminescence panel 50 reaches the bonding substrate 30, the intensity of the light varies depending on the path through which the light has passed. However, since the light diffuses when passing through the inside of the bonding base material 30, when the light reaches the decorative veneer 20, such light intensity difference is eliminated, and the light with reduced emission unevenness is suppressed. 20 is reached. Accordingly, even when the reinforcing portion 40 is provided, the light from the electroluminescence panel 50 is diffused inside the bonding base material 30, and thus the light is applied to the decorative veneer 20 with light emission unevenness suppressed. Permeated. That is, in the present invention, since the joining base material 30 is disposed between the reinforcing portion 40 and the decorative veneer 20, even if the reinforcing portion 40 has a three-dimensional structure, the uneven light emission caused thereby is joined. It becomes possible to absorb the light in the base material 30 and make the light reach the decorative veneer 20 evenly.

  Further, in the present invention, since the decorative single plate 20 is arranged on the one surface 51 side of the electroluminescent panel 50, the light from the electroluminescent panel 50 is applied when the electroluminescent panel 50 is turned on. Seen through board 20. Then, when the electroluminescence panel 50 is turned off, the decorative veneer 20 itself can be seen. Since the decorative veneer 20 is provided with a specific pattern in advance, when the electroluminescent panel 50 is turned on, the electroluminescent panel 50 and the decorative substrate 20 cause a decorative function by illumination. And even when the electroluminescent panel 50 is turned off, the decorative base material 20 having a specific pattern fulfills a decorative function. Therefore, in the present invention, it is higher than the beauty that can be formed by the fabric as described in the prior art. An aesthetic appearance can be generated.

It is a disassembled perspective view of the decoration apparatus based on embodiment of this invention. It is another disassembled perspective view of the decoration apparatus shown by FIG. It is a side view of the decoration apparatus based on embodiment of this invention. It is a perspective view of the reinforcement part of the decoration apparatus based on this invention.
