Abstract

PURPOSE:To cut cost and improve external appearance by forming a hollow part for the insertion of rubber basic material at the part corresponding to the periphery of a carpet in the upper and lower metal molds for shaping the captioned mat and fixing the rubber mat integrally onto the periphery of the rubber sheet. CONSTITUTION:A common carpet 11 is loaded onto a lower mold 12, with the pile thread underside. A rubber sheet 13 attached from the back surface of the carpet 11 is cut a little larger than the carpet 11. A lower mold 12 having a plurality of vacuum suction passages 15 inside and a concaved part 12a where a hollow part is formed when superposed with the upper mold 14 having a heating source built-in are formed at the part surrounding the periphery of the carpet 11 on the surface of the lower mold 12. Therefore, the lower mold 12 and the upper mold 14 are pressed and heated, and the rubber sheet 13 and a rubber basic material 17 are fixed integrally onto the carpet 11, and thus a carpet mat 18 is finished.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved structure of a carpet mat used for laying on the floor of a vehicle such as an automobile.

PRIOR TECHNOLOGY Conventional carpets are formed by laying a large number of pile yarns on one side of a base material made of synthetic resin or non-woven fabric, etc. However, in the case of carpet mats for vehicles, there are additional layers to the above-mentioned carpet. It has been lined to increase its strength. -f”
The material used here is a curved comb sheet, which is manufactured by heating and rotating the rubber 7-toe from 1) dl of the carpet.

That is, the conventional carpet 1 shown in FIG. Inside the lower mold 2, several vacuum suction passages 3.3 are provided, and the vacuum suction passages 3.3 are collectively sucked into a vacuum as shown by arrow A. On the other hand, the rubber sheet 4 is brought into contact with the back side of the pet 1, and the rubber sheet 4 is heated while pressing the upper mold 5 which has a built-in heating source, and the rubber sheet 4 and the carpet 1 are bonded together as shown in FIG. As shown in the figure, it is fixed by vulcanization adhesive. In addition, the vacuum suction path 3,
3 to vacuum the pile yarn side of the carpet, it is possible to prevent the pile yarn from "falling over."

Furthermore, in addition to the structure mentioned above, a mat structure in which a rubber mat is formed around the carpet 1 to increase the area to be laid on the floor has also been considered. In addition to the structure shown in the figure, I'm also thinking of manufacturing the carpet mat by separately attaching and forming a rubber mat in a post-process, or by coating the periphery of the carpet mat with rubber or resin.

However, in the method of making a car head mat for a vehicle with a rubber mat, there is an increase in the number of man-hours due to the addition of a sub-layer process for the rubber mat, and there is a problem in maintaining the appearance of the finished product. This method has disadvantages in that it is difficult and has a protrusion point, leading to increased manufacturing costs and variations in quality.

Means for Solving the Problems In order to solve these problems, the present invention is designed to solve the problems in the upper and lower molds for molding carpet mats for vehicles.
7.A part corresponding to the periphery of the carpet.A hollow part is provided into which the rubber fabric is inserted.From this, the surface side of the carpet I.
The main object of the present invention is to obtain a carpet mat for a vehicle, which is characterized in that a rubber mat is integrally formed in a solid layer around a heat-fixed rubber sheet.

Function: With the above structure, when a rubber sheet is fixed to the back side of a carpet using upper and lower molds, it becomes possible to simultaneously mold a rubber mat around the carpet and integrally with the rubber sheet.

This has the effect of greatly simplifying production and improving cost and appearance characteristics.

EXAMPLES Below, the present invention will be described in detail based on examples and drawings. In the configuration shown in FIG.

An ordinary carpet 1) is placed on a lower mold 12 with its pile yarn facing downward. The rubber sheet 13 that is brought into contact with the carpet 1) from the back side is cut to be slightly thicker than the carpet 1). 14 is an upper mold with a built-in heating source. There are multiple vacuum suction passages 15 inside the lower mI2.
15... are provided, and these vacuum IK lead paths 15
．． 15 are gathered into room 16 and sucked into one space as shown by arrow B.

Furthermore, a concave portion 12a, in which a hollow portion is generated when the lower mold 12 and the upper mold 14 are superposed, is formed on the surface of the lower mold 12 and in a region surrounding the carveler (1).

Inside this recess 12 a, there is a rubber fabric 1 made of untreated raw rubber, etc.
Insert 7. The rubber fabric 7 is set around the rubber sheet 13 and at a position close to the rubber sheet 13.

From the set state as described above, the rubber sheet 13 and the rubber fabric 17 are integrated into the carpet 1) by pressing the upper mold 14 and the lower mold 12 under appropriate pressure and heating them.
The carpet mat 18 shown in FIG. 2 is completed. That is, a rubber sheet 13 is placed on the back side of the carpet 1).
is fixed thereto, and a rubber mat 19 is formed integrally with this rubber sheet 13, forming a carpet mat 18 having a large area as a whole. Rubber sheet 1
3 and rubber mat] 9 are vulcanized and bonded, so the adhesive strength is high and the overall structure can be manufactured as a simple carpet mat. Furthermore, vacuum suction 8a15.1
It goes without saying that "falling down" of the pile yarns can be prevented by vacuum suctioning the pile yarn side of the carpet using 5.

According to the dual-use carpet mat with rubber mat according to the present invention, which has been described in detail, the rubber mat and the rubber mat can be simultaneously vulcanized and fixed together with the carpet, so that a single operating means is required. Therefore, fixing of the rubber 7-t to the carpet and hardening of the rubber mat to be formed around the rubber 7-t are also carried out at the same time.

The manufacturing process can be changed and simplified. Therefore, the effect on Jll productivity and cost due to process reduction is large, and the appearance characteristics desired on the front and back of the completed carpet mat are good, and the luxurious feeling of the carpet is combined while maintaining the heavy feeling of the mat. It can be used as a carpet mat for two-way use, and is useful.
