Detailed Description of the Invention The present invention relates to a tatami mat covering device, one of which is to grasp and stick a tatami mat cover partially on a tatami floor in a direction, and to fix the arrangement of the tatami floor and tatami mat. The other purpose is to make the work more efficient by comprehensively releasing the support in the above-mentioned bonding. In the process of manufacturing tatami mats, the tatami floor and tatami facing are made through structured work processes, but the attachment of the tatami floor and tatami facing is still often done by hand, and although there are attempts to mechanize it, Mechanized work was accompanied by dissatisfaction in the following points. In other words, as shown in Figure 1, the grass on the tatami surface is lined up horizontally, but the horizontal line A-A' is not necessarily perpendicular to the vertical direction, and is not parallel to the horizontal line B-B' at the end of the tatami floor. Or a portion also occurred. When the lines A-A'' and B-B'' are not parallel, the tatami may appear distorted, making it unsightly. In the case of manual work, it is possible to remove the distorted feeling by partially pulling the tatami mat and fixing it with pins, but this is difficult to do with machine work and has not yet been achieved. The present invention was made for the purpose of meeting that need.
The present invention will be described in detail below based on the embodiments shown in FIGS. 2 and 3. One of the present inventions is to provide support arms 2.2' fixedly to the support base 1 on both sides of the longitudinal end of the support base 1 covering almost the entire area of the tatami floor, and to place the support arms 2.2゛ on the support base 1. The arms 3, 3' on both sides are rotatable about the horizontal line position on the upper floor of the upper end of the tatami mat, and the arms 3, 3' are continuously fixed to the tatami surface by a pivot 17 with the abutting plate 4. A ruler 5 is hinged to the edge of the arm 3, several presser plates 6 are hinged at equal intervals to the upper side of the corresponding plate 4, and the hinges have an elastic structure that is biased in the opening direction. A support shaft 9 is horizontally suspended above the holding plate 6 by passing through the bearing 7 formed in the middle part of each 3" and the bearing 8 protruding from the holding plate 4 to avoid contact with each holding plate 6. , a cam lO is provided which loosely fits on the support shaft 9 and is in contact with the upper surface of each presser plate 6, and each cam lO is provided with a rotating lever handle 11 to constitute an independent pressing mechanism for each presser plate 6. In the figure, 12 is the tatami floor, and 13 is the tatami mat.
The tatami mat 13 placed on top is folded back along the end of the ruler 5 placed in the extension direction of the backing plate 4, and the end of the folded tatami facing intervenes between the backing board 4 and the holding board 6, The cam 10 is rotated and tightened with the lever handle 11 in hand, and the presser @6 is pressed and held between the two plates. And arm 3,3
At the same time, the support plate 4 and the like are rotated as shown by arrow C at the pivot points of the support arms 2 and 2, and the tatami cover 13 is hung over the end face of the tatami floor 12 as shown by the chain line, and the sewing operation begins.14 shows a meshing tooth pattern that prevents sliding when the tatami surface is held between the backing plate 4 and the holding plate 6. The ruler 5 is used to define the folding position when folding the tatami mat as described above, and when there is a gap E between the end of the ruler and the end Ni1 of the tatami floor, the arms 3, 3゛ will rotate in the direction of the arrow C. When done, the tatami surface is forced to elongate approximately twice the distance E, creating tension in the tatami surface along the tatami floor. In order to obtain this tension, in conventional hand-stitching methods, methods such as curving the tatami floor and tightening the tatami face have been taken. When using the device of the present invention, the pressing plate 6 that holds the tatami mat
are distributed at several locations, and the tatami surface can be partially pulled and the lever handle IO can be rotated and fixed for each section. Therefore, it is easy to fix the lines of grass in each part on the line along the edge of the tatami floor, giving the finished tatami a neat and stable aesthetic appearance. The sewing machine is usually a member of a sewing machine equipped with a supporting stand and a sewing machine. Another feature of the present invention is that, in addition to the above configuration, a lever handle 15 for rotation is provided on the support shaft 9, and the lever handle 1 of each cam 10 is
The protrusions 16 that engage with the respective protrusions 16 . The cam lO is also rotated via the lever handle 11, and a general opening mechanism is constructed in which the pressure of the cam lO is released at the same time. That is, in order to fix the tatami mat, lever handles 11 which arbitrarily operate several cams are individually operated, but when releasing the tatami mat, each lever handle 110 is simultaneously rotated by a single lever bundle 15. This has the effect of making the tatami mat work more efficient. 4. Brief description of the drawings Figure 1 is a plan view schematically showing a part of the tatami manufacturing process.
