Description

[Detailed description of the device] [Industrial applications]

 This invention relates to a trunk floor carpet to be laid on the trunk floor of an automobile, and has a structure that allows the tools and spare tires stored in the recess of the trunk floor to be easily taken out.

[0002]

[Prior art]

 As conventional techniques of this type, there are JP-A-2-63244, 144831, JP-A-3-2832, 2834, and JP-A-4-113942. In Japanese Utility Model Laid-Open No. 2-63244, a hardboard that covers the opening of the tire storage recess is arranged on the lower surface of the carpet, and a hardboard is integrally attached to the carpet so as to cover the opening.

In Japanese Utility Model Laid-Open No. 2-144831, a felt sound absorbing material is laminated and attached to the back surface of the carpet body, and a portion for covering the recess for storing the spare tire is formed by cutting out a lid with one side as a hinge to open and close the recess for storing. The felt material is formed into a hard part with shape retention by thermocompression molding. No. 3-2832 is a back layer member made of polyurethane elastomer integrally formed on the back surface of a skin member by cast molding, and a plurality of thin portions are formed at predetermined places on the back layer member. No. 2834 has a plurality of back layer members made of a polyurethane foam layer formed on the back surface of the skin member and can be folded at a place where the back layer member is not formed.

Japanese Patent Application Laid-Open No. 4-113942 was previously filed by the present applicant, and in the portion subjected to the turning action, a plurality of intermediate layers having a large bending rigidity and having a width shorter than the height of the trunk are parallel to each other. The composite felt consisting of the surface non-woven fabric and the fibrous base material layer is laminated on one side and the back side of the composite felt is laminated on the other side, and the gap and outer circumference of the intermediate layer are welded and thinned by press molding under heat. Is.

[0005] In Japanese Utility Model Laid-Open No. 2-63244, no spare tire repair work is carried out. In Japanese Utility Model Laid-Open No. 2-144831, it is difficult to hold the lid part formed by cutting out one side as a hinge in the open position and trying to return to the original position, so the opening angle cannot be kept large and the spare tire It is inconvenient when both hands are blocked, such as when taking out.

In Japanese Utility Model Laid-Open Nos. 3-2832 and 2834, it is difficult to find a spare tire in the center of the trunk depending on the shape of the trunk simply by folding the carpet. Becomes unstable. In Japanese Patent Laid-Open No. 4-113942, the tool entry part stored on the trunk floor side can be easily taken out by opening one piece of carpet on the side part by a hinge action, but the center part such as a spare tire has a folding carpet It turns out that it becomes an obstacle depending on the shape. Also, when the skin layer is continuously molded integrally to form a thin portion for use as a hinge, the thin portion is hard due to the molding and has high rigidity, and it is likely that complete folding cannot be performed in use. There are problems as described above.

[0007]

[Problems to be solved]

 There was a problem that tools and spare tires stored on the trunk floor could interfere with the floor carpet laid on top of them, and they could not be easily taken in and out. .

[0008]

[Means for solving the problem]

 In this invention, "the shape of the trunk floor carpet is the hinge part 1 in the front part of the boundary between the parts on both sides and the center part, and the front part is slit 4 as much as the spare tire can be inserted and removed. A thick interior non-woven fabric in which a part has a plurality of hinges in the width direction, and the structure is a rigid core material with a skin material on the front surface and a core material on the back surface. Alternatively, the felt is welded to the skin material on the outer periphery of the core material, and the back surface non-woven fabric or felt between the core material and the felt forms a discontinuous portion to perform a hinge action. Floor carpet. "Was able to solve the problem.

As the core material used here, a hard board, a veneer board, a corrugated board, a compression resin felt, a plastic board or the like having a large rigidity is used. Carpet, non-woven fabric, etc. with resin on the back surface is used as the skin material. Thick non-woven cloth or felt is impregnated with a binder, or thick non-woven fabric or fibers with a relatively low melting point are mixed in the constituent fibers of the felt. In addition, those non-woven fabrics or those obtained by laminating another non-woven fabric on the surface of the non-woven fabric or a felt (composite non-woven fabric or composite elto) are used.

As a construction method, a thick non-woven fabric of the back side can be formed by molding a thick non-woven fabric or felt on the back side of which is formed between the molds having the convex parts to which the lower mold concave upper mold fits so that the core material fits. Set it as a molding felt in the mold recess and set the core material in the recess of the molded non-woven fabric or molding felt, and then heat the surface material on which the backside resin is melted and heat the surface material on the flat side with the resin side facing the core material side. Press with a mold to weld the skin material to the surface of the core material and the non-woven fabric or felt on the outer surface of the core material. A product can be obtained by slitting and cutting the periphery with a blade at the same time as pressing.

[0011]

[Action]

 The hinge part has no thick non-woven fabric layer or felt on the back side and is made of only the skin material. It is easy to bend so that only that part does not have high rigidity. At the boundary between both sides of the floor carpet and the center, the front part is hinge 1 and the front part is slit 4 so that spare tires can be easily taken in and out. The carpet has slits so that it can be folded from front to front. The center floor carpet is provided with hinge portions 2 and 3 in the width direction so that it can be folded.

[0012]

[Example] A 700 g / m ² felt made of 70% polyester cotton and 30% polypropylene cotton was heated and press-molded so that the core material would fit, and the lower floor mold of the trunk floor shape was backed as shown in FIG. A recess was formed so that the molding felt 9 and the core member 6 could be fitted together. The molding felt 9 is set in the lower mold, and then the core material 6 is set, and 100 g / m ² of styrene-butadiene latex is applied to a non-woven fabric made of polyester cotton of 400 g / m ² and dried, and 600 g / m ^{2 of} polyethylene is applied to the back surface. Amount of melt-coated non-woven carpet 8 is heated in a heating furnace and the polyethylene surface on the back side is melted and pressed with a flat plate mold with the resin surface facing the core side, and at the same time both side parts by the blade mold installed in the upper mold. At the boundary between the center and the center, a slit 4 was cut at the distance where the spare tire could be taken out from the front side, and the outer periphery was cut. The turning prevention magnet 10 and the turning clip 11 were attached to complete the product.

In the case of the trunk floor, this is the product, but in the case of the luggage floor carpet, the seat back material is attached to the front end of the central portion by sewing or the like to become the product. When this tool was mounted on a car and the tools and spare tires were checked in and out, opening the tools with the left and right turning clips made it possible to open and close easily with an opening angle of approximately 180 ° due to the hinge action. After returning to the original state and opening the center part from the front to the hinge parts 2 and 3 at an angle of about 180 °, spare tires could be easily put in and taken out.

[0014]

[Effect of device]

 In the present invention, the hinge part of the trunk floor mat is made of only the skin material, so that an opening angle of about 180 ° can be achieved, and the front part 1 at the boundary between both side parts and the central part is the hinge processed part, and the front part Slit the part as long as the spare tire can be slit to form the slit 4, and the center part can be opened by folding the hinge parts 2 and 3 of the center carpet by the distance of the slit 4. By doing so, not only tools but also spare tires can be easily put in and out. Also, by using a rigid core material as the core material except for the hinge part of the slit part, a flat flat state is maintained even when loading heavy objects, and the carpet is dented in the recess by luggage so that the load becomes unstable. That was gone.
