Description

  The present invention relates to a dashboard mat laid on a dashboard of an automobile, and relates to the above-described mat provided with a function for preventing temperature rise in the vehicle.

  Automobile dashboards are heated by direct sunlight and cause the temperature inside the car to rise. In addition, as the windshield becomes larger, the area of the dashboard tends to increase. When the sunlight is strong, the in-vehicle temperature does not easily decrease even if the temperature setting of the cooling device is lowered.

  On the other hand, currently available dashboard mats have functions to protect the dashboard from direct sunlight and prevent deterioration of the dashboard surface, but the effect of measures against heat inside the vehicle is not expected.

  The following Patent Document 1 proposes a non-slip mat used on a dashboard in order to prevent small items such as glasses placed on the dashboard of an automobile from sliding down, and silicon rubber is used as the mat. It has been shown that the mat can be fixed on the dashboard and can be prevented from sliding on the dashboard even when the automobile is stopped or turned.

  Patent Document 2 discloses a cooling zone formed by wrapping a fiber or a nonwoven fabric made of a highly hydrous resin with a cloth having water conductivity or transpiration. This cooling zone is applied to the part of the human body such as the forehead where the water impregnated in the highly hydrous resin is evaporated at the body temperature, and the part where the cooling zone is applied and its surroundings are cooled by the heat of vaporization. It is to do.

  Further, Patent Document 3 discloses a sheet having a three-layer structure including a water retention layer, a waterproof sheet, and a non-slip layer, and the water retention layer includes water so that the water retention layer is provided on the roof of the automobile or the roof or wall of the prefabricated building. A cooling sheet is shown that prevents the inside of a vehicle or a prefabricated building from being heated by solar heat due to the heat of vaporization when water contained in the water retaining layer evaporates by being mounted outside. Patent Document 3 exemplifies a sponge layer as the water retention layer, and exemplifies a resin-made magnet sheet having flexibility as a slip stopper.

  Due to the direct sunlight, the temperature inside the car rises greatly. During the period from spring to early autumn when the sunlight is strong, it is essential to operate the cooling system. Unlike heating that uses the heat generated by the engine, however, it requires economical fuel and electricity to lower the temperature inside the vehicle, making it economical. Not only will the burden increase, it will also contribute to global warming. If the temperature rise in the vehicle can be suppressed without using fuel or electricity, the occurrence of such problems can be reduced.

  By attaching the cooling sheet shown in Patent Document 3 on the roof or bonnet of an automobile, watering from above and allowing the water retaining layer to contain water, the inside of the parked automobile is heated to high temperatures by solar heat. It is thought that it can suppress becoming. However, such a cooling sheet cannot suppress an increase in the temperature of the vehicle running. This is because such a seat attached to the outside of the vehicle may fall off during traveling.

  In addition, the cooling sheet attached to the outer surface of the vehicle body of the automobile cools the outer surface of the vehicle body, so that the cooling efficiency is poor. That is, since the heat of vaporization when the water in the water retaining layer evaporates is taken away from the outer surface of the vehicle body and the ambient air around it, much of the heat of vaporization is consumed to cool the outside air, and the water that evaporates. The effect of suppressing the temperature rise in the vehicle is small compared to the amount of.

  An object of the present invention is to obtain a technical means capable of effectively suppressing temperature rise in a car due to sunlight even during traveling without consuming fuel or electricity, and is easy to handle and cool. The challenge is to obtain a dashboard mat that is highly durable and does not hinder the usability of the dashboard.

  The present invention includes a water retention layer 2 made of fibers having high water absorption and good transpiration, a waterproof sheet 3 that covers the water retention layer from the bottom to prevent water leakage from the water retention layer 2, and an automobile dashboard By providing a mat that is flexible as a whole in a three-layer structure with a non-slip 4 that prevents sliding on the top, and having a shape and size suitable for mounting on a dashboard of an automobile, The problem is solved.

  It is assumed that the water retaining layer 2 and the waterproof sheet 3 have shapes and dimensions that do not hang down when they are placed on a dashboard of an automobile and do not cause a wide gap between the windshield and the side wall. The anti-slip 4 may be provided so as to cover the entire surface of the waterproof sheet 3 on the side of the anti-water retention layer, or may be attached so as to partially cover the side of the waterproof sheet 3 on the side of the anti-water retention layer. The water-retaining layer 2 can be formed of natural fiber or synthetic fiber towel cloth or a highly water-containing resin, but it is most preferable to use a microfiber mat.

  The mat made of microfiber has a high moisture content, a large amount of water retention, excellent transpiration of the retained water, can be washed, and dries quickly after washing. On the other hand, normal fiber towels and the like have a low moisture content, so that the contained water evaporates in a relatively short time, and the duration of the cooling effect is short. On the other hand, a highly water-containing resin has a high water content but a poor transpiration property. Therefore, when the mat is soiled and washed, it takes several days to dry, which is inconvenient and has a small cooling effect due to the small amount of water that evaporates during use.

  The waterproof sheet 3 is preferably attached with its peripheral edge 33 folded back so as to cover the edge 23 of the water retention layer 2. With such a structure, it is possible to effectively prevent water from seeping out from the periphery of the water retention layer 2.

  Placing a wet towel on the dashboard that has been heated by the sun will improve the cooling effect, resulting in a more comfortable interior. This is thought to be due to the fact that water contained in the towel is evaporated by solar heat, and the dashboard is cooled by the heat of vaporization at that time, thereby suppressing an increase in the interior temperature. However, with towels, the top of the dashboard gets wet and the water retention capacity of the towels is low, so the effect is not sustainable and it is necessary to include water frequently. Handling was inconvenient, such as having to pay attention to the amount of

  In the dashboard mat of the present invention, the water retaining layer 2 is formed of fibers having excellent water retention and transpiration, so that the water contained in the water retaining layer 2 is continuously evaporated over a long period of time, thereby providing good cooling. Since the effect is exhibited for a long time, the operation of frequently including water is unnecessary, and drying after washing is quick and convenient for handling. Since the lower surface and the peripheral edge of the water retaining layer are covered with the waterproof sheet 3, it is possible to prevent water from seeping out from the lower surface and the peripheral edge of the water retaining layer 2. In particular, the edge 23 of the water retaining layer is wrapped with the peripheral portion 33 of the waterproof sheet folded upward The structure can prevent water leakage even when water is trapped at the folded portion of the waterproof sheet and the water retaining layer 2 contains too much water. Further, the anti-slip 4 can prevent the mat from slipping down from the dashboard when stopping or cornering.

  By placing the dashboard mat of the present invention on the dashboard of an automobile and including an appropriate amount of water, the dashboard can be cooled by the heat of vaporization when the water evaporates. A certain dashboard is cooled, and the cooling effect is improved. As a result, the interior of the vehicle becomes comfortable and the fuel consumption during operation of the cooling device is improved.

  1 and 2 are views showing a first embodiment of the present invention. The dashboard mat of the first embodiment has a shape in which the water retaining layer 2, the waterproof sheet 3, and the anti-slip sheet 4 are matched to the shape of the upper surface of the automobile dashboard, or a shape that covers most of the upper surface of the automobile dashboard. The whole is made into a three-layer structure by sewing the periphery.

  The water retention layer 2 has a structure in which flexible fiber bundles 22 made of microfibers are densely planted on the surface side of the base fabric 21, and is a well-known structure as a microfiber bath mat. Microfiber is a fiber such as nylon or polyester with a fiber cross-section with an acute angle or polygonal shape and a thickness of about 10 microns or less. It has water absorption and breathability equivalent to or better than cotton, and is unique to synthetic fibers. Has quick-drying.

  When sewing the periphery of the water retaining layer 2, the waterproof sheet 3 and the anti-slip sheet 4, the waterproof sheet 3 is cut slightly larger than the water retaining layer 2, and the peripheral portion 33 is folded upward to wrap around the edge 23 of the water retaining layer 2, At the folded portion, that is, at the four layers of the waterproof sheet 3, the water retaining layer 2, the waterproof sheet 3, and the anti-slip sheet 4 from the front side, the seam is sewn. In the example of the figure, the edge 23 of the water retention layer is formed on the periphery of only the base fabric 21 where the fiber bundles 22 of microfibers are not planted, and the edge 23 only of the base fabric is formed on the folded portion 32 of the waterproof sheet 3. Wrapped inside. In this way, by folding the peripheral edge portion 33 of the waterproof sheet and wrapping the edge 23 of the water retention layer, it is possible to prevent water from dripping or seeping out from the edge 23 of the water retention layer containing water.

  The waterproof sheet 3 may be a general synthetic resin sheet that does not allow water to pass therethrough, and the anti-slip sheet 4 is a high friction body sheet such as a silicone rubber sheet having a mesh structure.

  3 to 5 are views showing a second embodiment of the dashboard mat according to the present invention. The shapes of the water retaining layer 2 and the waterproof sheet 3 and the materials of the water retaining layer 2, the waterproof sheet 3 and the anti-slip sheet 4 are shown. Is the same as in the first embodiment. In this second embodiment, the anti-slip sheet 4 is partially attached to the back surface (surface on the side of the water retaining layer) of the waterproof sheet 3 and is decorated so as to wrap the mat periphery having the same structure as that of the first embodiment. The first embodiment is that a bias tape 5 is attached, and two pairs of long and short cuts 12 and 13 are provided from the front edge of the mat, that is, the edge 11 on the driver and passenger side. Different.

  Many recent automobiles are equipped with SRS (Supplemental Restraint System), a shock-absorbing balloon that inflates in front of the driver's seat and front passenger seat due to the impact of a collision. Is stored under the dashboard, and a top surface of the dashboard is provided with a lid that opens when the balloon is inflated. This lid is opened by swinging the front side, that is, the passenger seat side upward.

  The cuts 12 of the second embodiment are provided at positions that match the left and right edges of the SRS lid. By providing such an incision 12, when the SRS operates, the portion between the two long incisions 12, 12 swings upward together with the lid of the SRS, so that the smooth operation of the SRS is not hindered. .

  Some dashboards are provided with an accessory case such as glasses. Such an accessory case lid is configured such that the driver's seat side swings upward as with the SRS lid. The short cuts 13 and 13 formed in the dashboard mat of the second embodiment are provided in accordance with the sides of the lid of the accessory case. By providing such a cut 13, the short cuts 13 and 13 are provided in the dashboard. The operation of opening and closing the lid of the accessory case can be performed smoothly.

  The anti-slip sheet 4 of the second embodiment is provided by attaching a plurality of rectangular shapes to the back surface of the waterproof sheet 3 at intervals. It is convenient that the non-slip sheet 4 partially provided on the back surface of the waterproof sheet 3 is attached by attaching its peripheral edge to the back surface of the waterproof sheet 3 by heat fusion or the like.

  If such a rectangular anti-slip sheet 4 has a structure in which only one of the four sides is not adhered, a bag having the one side as a bag mouth is formed between the waterproof sheet 3 and the anti-slip sheet 4. be able to. This bag can be used as a bag containing a deodorant. Such a bag can also be formed by cutting a part of the surface of the non-slip sheet 4 of the first embodiment.

  The dashboard mat of the present invention cannot exhibit a cooling effect when the water retaining layer 2 is dried. Therefore, when the water retaining layer 2 is dried, it is necessary to pour water from the top of the dashboard mat 1 with a cup or bottle. Whether the water-retaining layer 2 is dry or not can be determined at first glance. Therefore, a synthetic fiber such as a light-colored fiber that turns black when wet with water or a fiber that changes color due to a temperature change (temperature-sensitive discoloration fiber) can be used. By arranging it, it becomes possible to judge at a glance whether the water-retaining layer 2 contains water or is dry (in the case of a temperature-sensitive discolored fiber, the temperature is increased by drying). .
