Japanese Unexamined Patent Publication No. 2003-210308

The vehicle mat described in Patent Document 1 has a flat shape, but the floor surface of the vehicle has a curved surface shape, and the vehicle mat is often laid along the curved surface shape. .. However, if the mat for a vehicle described in Patent Document 1 is relatively thick or has a light emitting body and has a flat shape, the curved surface of the floor surface of the vehicle is used. There is a risk that some parts may float without following the shaped part. Further, for example, if the base member constituting the vehicle mat described in Patent Document 1 is molded into a shape along the floor surface of the vehicle, the thickness of the mold increases and the manufacturing cost increases. Become.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a vehicle mat that can easily follow the floor surface of a vehicle while suppressing an increase in manufacturing cost.

In order to solve the above problems, the vehicle mat of the present invention
A vehicle mat that is laid on the floor surface of a vehicle, including a curved surface formed in a curved surface.
A mat body formed in a flat shape and a streaky member formed in a streak shape along the curved surface portion are provided.
By attaching the streak member to the mat body, it is characterized in that it has a shape along the laying location.

In the vehicle mat having this configuration, the mat body having the largest size among the constituent elements is a flat molded product, and the streak members smaller than the mat body are a three-dimensional molded product. Then, the vehicle mat having this configuration has a three-dimensional shape in which the mat body is held in a shape along the streak-shaped member by assembling them. If the mat body is molded into a shape that follows the laying location, it can easily follow the laying location including the curved surface, but the mold required to mold the mat body becomes large. Speaking of which, the thickness of the mold becomes large and the cost increases. On the other hand, the streak member may be formed by using a mold, but for example, it may be formed along a curved surface portion by secondary processing into a three-dimensional shape after extrusion molding. That is, the cost of the three-dimensionally shaped streak member can be significantly reduced as compared with the three-dimensionally shaped mat body. Therefore, the vehicle mat having this configuration can easily follow the laying location on the floor surface of the vehicle while suppressing an increase in manufacturing cost.

The streak-like member in the vehicle mat having this configuration may be arranged on the back surface side of the mat body or may be arranged on the front surface side. For example, if the members arranged on the surface side and constituting the design of the vehicle mat are used as the streak members, it is not necessary to newly prepare the streak members, and the increase in cost can be further suppressed. .. Further, the streak member is not limited to a hard material such as metal, and may be a soft material made of resin as long as the shape of the mat body can be maintained to some extent.

In the above configuration, the mat body may have ribs extending linearly on the back surface side, and the ribs may have a weakened portion formed at a portion corresponding to the curved surface portion.

Although the vehicle mat having this configuration has ribs that increase the rigidity of the mat body, the weak portion formed on the ribs makes it easy to hold the mat in a shape along the laying location. That is, the vehicle mat having this configuration has a higher followability to the laying location.

Further, in the above configuration, the mat body has a streak-shaped opening that opens on the upper surface side, and the vehicle mat is provided along the opening and emits light from the opening. The device may be provided and the lighting device may be configured to function as the streak member.

The vehicle mat having this configuration can be given an effect of light by a lighting device. If the vehicle mat provided with this lighting device is configured in a planar shape, for example, it is more difficult to follow the laying portion including the curved surface portion. Since the lighting device of the vehicle mat having this configuration is formed in a shape along the curved surface portion, when the mat is assembled to the mat body, the vehicle mat has a shape along the laying place and can be easily placed at the laying place. It can be made to follow.

Further, in the above configuration, the lighting device includes a light emitting body including a plurality of light sources and a longitudinal substrate on which the plurality of light sources are arranged, and a longitudinal housing that houses the light emitting body inside. The accommodating member has a member, and the accommodating member is formed in a shape along the curved surface portion, and can be configured to function as the streak-shaped member.

The vehicle mat having this configuration is limited to the configuration of the lighting device described above. For example, consider a vehicle mat configured by attaching a light emitting body to a linearly formed accommodating member and attaching the accommodating member to a flat mat body. When a vehicle mat having such a configuration is laid at a laying location including a curved surface portion, the substrate of the light emitting body is attached to the accommodating member and then bent together with the accommodating member, so that a relatively large tension (stress) is applied to the substrate. ) Is applied, which is electrically unfavorable. In addition, the positions of the plurality of light sources with respect to the mat body may be displaced. On the other hand, in the vehicle mat having this configuration, since the light emitting body is attached to the accommodation member having a three-dimensional shape, the tension applied to the substrate as described above is suppressed and the position of the light source is displaced. It becomes possible to prevent.

According to the present invention, it is possible to provide a vehicle mat that can easily follow the floor surface of a vehicle while suppressing an increase in manufacturing cost.

The piles 31 are planted on the base cloth 32, and the seams protruding on the back side of the base cloth 32 are made of latex (rubber). It is coated with 33 and fixed, and a backing cloth (linen / non-woven fabric) 34 is pasted on the back side of the latex 33. Then, the carpet 12 is adhered to the main body 20 of the base 11 by the adhesive tape 35. The pile 31 is a cut pile in which the ends of the hair are cut and aligned. However, the pile is not limited to the cut pile, and may be a loop pile or a mixture thereof.

From the above configuration, the floor mat 10 of the present embodiment is mainly composed of a mat body 40 composed of a base 11, a carpet 12 arranged on the upper side of the base 11 and softer than the base 11. It has become. The mat body 40 is formed with an opening 41 formed in the base 11 and a slit 12A of the carpet 12 so as to communicate the base 11 and the carpet 12 and open an opening 41 on the upper surface side of the carpet 12. There is. The opening 41 is a linear (streak-like) groove extending in the front-rear direction of the vehicle. The opening 41 is also opened on the lower surface side of the base 11 to be a through hole. Incidentally, the mat body 40 is also formed with two circular openings 42 on each of the left and right sides on the rear side of the vehicle, and the grommet 43 is attached to the circular openings 42. The grommet 43 is for inserting a locking member (not shown) such as a hook provided on the laying point FL side to prevent the floor mat 10 from being displaced with respect to the laying place FL.

The floor mat 10 of this embodiment includes a plurality of lighting devices 50 forming the light emitting unit 13. The plurality of lighting devices 50 are arranged in each of the plurality of openings 41 of the mat body 40. Each illuminating device 50 has a longitudinal shape extending in the front-rear direction of the vehicle. Specifically, as shown in FIG. 3, each lighting device 50 mainly includes an LED unit 54 including a plurality of LEDs 51 as a light source, a longitudinal substrate 52, and a housing 53 accommodating the substrate 52. It is configured as. The LED unit 54 functions as a light emitting body, and a plurality of LEDs 51 are mounted side by side on a longitudinal substrate 52 along the longitudinal direction thereof, and the substrate 52 is housed in a housing 53. It has become a thing.

Further, each lighting device 50 includes a diffusing member 60 for diffusing the light of the LED unit 54. The diffusion member 60 is formed of a light-transmitting and flexible material such as soft acrylic or silicon. As shown in FIG. 3, the diffusion member 60 is composed of a bottom surface side member 61 for fixing the LED unit 54 to the upper surface, and an upper lid member 62 for covering the upper side of the bottom surface side member 61. .. The bottom surface side member 61 has a groove-shaped base portion 61A for fixing the LED unit 54, and a pair of flange portions 61A projecting to the left and right sides of the base portion 61A. On the other hand, the upper lid member 62 includes a pair of wall portions 62A erected in a state of facing the vehicle width direction and extending in the vehicle front-rear direction, and a top surface portion 62B formed so as to connect the upper ends of the pair of wall portions 62A. A pair of flange portions 62C projecting to the left from the left wall portion 62A and to the right from the right wall portion 62B. Then, the pair of flange portions 61B of the bottom surface side member 61 and the pair of flange portions 62C of the upper lid member 62 are adhered to each other by the adhesive tape 63, so that the diffusion member 60 has a hollow shape. That is, the diffusion member 60 functions as an accommodating member for accommodating the LED unit 54, which is a light emitting body, inside.

Further, as shown in FIG. 2, the bottom surface side member 61 and the upper lid member 62 constituting the diffusion member 60 are formed into a three-dimensional shape in which the front side portion rises upward. Specifically, as shown in FIG. 6, the laying location FL on which the floor mat 10 is laid has a shape in which the front side is raised including the curved surface portion FL _C formed in a curved shape on the front side, and the bottom surface is formed. side member 61 and the upper cover member 62 is what is formed in a shape along the curved surface portion FL _C. By the way, in this embodiment, a linear member is formed by extrusion molding, and then secondary processing (heating and plastic deformation) is performed so that the bottom surface side member 61 and the upper lid member 62 are placed on the laying point FL. It has a three-dimensional shape along it. The molding method is not limited, and the bottom surface side member 61 and the upper lid member 62 may be formed into a three-dimensional shape by injection molding or the like.

By attaching the LED unit 54 to the bottom surface side member 61 formed into the three-dimensional shape as described above and attaching the upper lid member 62 also formed into the three-dimensional shape to the bottom surface side member 61, each The lighting device 50 will have a three-dimensional shape. Each of the three-dimensional lighting devices 50 is fitted into the opening 41 from the lower surface side of the base 11, and the upper surface of the pair of flange portions 62C of the upper lid member 62 is adhered to the lower surface of the base 11 with adhesive tape 64. ing.

As described above, since each lighting device 50 has a three-dimensional shape, when it is assembled with the flat mat body 40, the mat body 40 is held in a shape along the lighting device 50. It will be. That is, the floor mat 10 has a three-dimensional shape along the laying location FL. Therefore, in this embodiment, it can be considered that each lighting device 50 functions as a streak member. Furthermore, the diffusion member 60 as a housing member constituting each lighting device 50, more specifically, the bottom surface side member 61 and the upper lid member 62 constituting the diffusion member 60 function as streaky members. It has become.

For example, when a floor mat having a flat shape is laid at a laying point FL including a curved surface FL _C , the floor mat may not sufficiently follow the laying place FL, and a floating (gap) may occur. is there. According to the present floor mat 10, since the floor mat 10 itself has a shape along the laying place FL, it can surely follow the laying place FL.

A plurality of positioning pins 70 are formed on the back surface of the base 11, and through holes 71 corresponding to the positioning pins 70 are formed on the diffusion member 60, and the positioning pins 70 and the through holes 71 are formed. The lighting device 50 is attached to the mat body 40 so as to match the above. In detail, the positioning pins 70 immediately provided behind the portion corresponding to the curved surface portion FL _C in the base 11 is a reference pin 70A. On the other hand, the through hole 71 corresponding to the reference pin 70A is a circular round hole 71A, and the through hole 71 formed in front of and behind the round hole 71A is a long hole 71B long in the front-rear direction. The 50 and the mat body 40 can be easily assembled.

By the way, if the mat body 40 (base 11) is formed into a shape along the laying point FL, it can easily follow the laying place FL including the curved surface FL _C. However, the mold required for molding the three-dimensionally shaped base 11 becomes large, and more specifically, the thickness of the mold becomes large and the cost increases. In this floor mat 10, since the bottom surface side member 61 and the upper lid member 62 as streaky members are molded by extrusion molding and secondary processing, it is compared with the case of molding the above-mentioned three-dimensional shape mat body. Therefore, the cost can be significantly reduced.

Although the back surface of the base 11 has ribs 22 are formed, on its rib portion 22, More particularly, the longitudinal rib 22A, which is cut a weakened portion at a location corresponding to the curved portion FL _C Since the notch 80 is formed, the mat body 40 is easily bent, and is easily held by the lighting device 50 as a streak member in a shape along the laying portion FL. That is, the mat body 40 can easily follow the curved surface FL _C , and the floor mat 10 has a higher followability to the laying point FL.

For example, consider a floor mat configured by attaching the LED unit 54 to a linearly formed accommodating member and attaching the accommodating member to the mat body 40. When a floor mat having such a configuration is laid at the laying point FL including the curved surface FL _C , the substrate 52 of the LED unit 54 is attached to the accommodating member and then bent together with the accommodating member. A large amount of tension (stress) is applied, which is electrically unfavorable. In addition, the positions of the plurality of LEDs 51 with respect to the mat body 40 may be displaced. On the other hand, in this floor mat 10, the LED unit 54 is attached to the diffusion member 60 (specifically, the bottom surface side member 61) which is a three-dimensionally shaped accommodating member, so that the substrate as described above is used. It is possible to suppress the tension applied to the 52 and prevent the LED 51 from being displaced.

In the floor mat 10 of the above embodiment, the lighting device 50 functions as a streak member, but in the vehicle mat of the present invention, the lighting device 50 is not an essential component. That is, the streak-shaped member may be arranged on the back surface side of the mat body and provided only for holding the mat body 40 in a three-dimensional shape. However, if a member constituting the design of the floor mat 10 is used as a streak member like the floor mat 10, it is not necessary to newly prepare a streak member, and an increase in cost can be suppressed. .. Further, in the floor mat 10, the streaky member is molded of a soft material made of resin (soft acrylic or the like), but is molded of a hard material such as metal, for example, the mat body 40 in order to enhance the design. A metal plate member such as aluminum arranged on the upper surface of the above can also be used as a streak member.

In the above embodiment, the floor mat is exemplified as the vehicle mat, but the present invention is not limited to this, and the vehicle mat of the present invention can be applied to the luggage mat and the like. Further, in the above embodiment, an automobile is exemplified as a vehicle, but the present invention is not limited to this, such as trains and amusement vehicles as ground vehicles, airplanes and helicopters as flight vehicles, ships as marine and underwater vehicles, and the like. The vehicle mat of the present invention can also be applied to a vehicle such as a submersible.
