Description

[Detailed Description of the Invention] The present invention relates to a sewing marking/cutting device for cutting fabric while marking sewing lines.

Conventionally, when cutting fabrics such as clothes, a pattern is placed on the fabric, sewing line marks are made along the pattern, and cutting lines are marked with an appropriate seam allowance from the pattern. After that, the fabric was cut along the cutting line.

Therefore, in consideration of the above points, the present invention is designed to mark the sewing line along the pattern and cut the fabric with an appropriate seam allowance at the same time, thereby improving work efficiency in cutting the fabric. The feature is that it is a cutting device that cuts the fabric while marking the sewing line, and the cutting device has a grip body, and a cutting mechanism and a marking mechanism that are arranged in parallel on the grip body. The cutting mechanism includes a cutting blade that can be freely adjusted in and out of the grip body, and a cutting guide plate that is made of an elastic material and extends in an upward arc from the protruding part of the cutting blade in the protruding direction. The marking mechanism includes a lurette pivotally supported by the tip of the support arm on one side of the cutting blade, and a case body supporting the proximal end of the support arm such that the distance between the lurette and the cutting blade can be adjusted and fixed. The case body has a gap with the grip main body at the upper part on the loop side, and the other end is fixed to the grip main body.

Hereinafter, embodiments of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a grip body made of resin, metal, etc. in an elongated shape;
A cutting mechanism 2 and a marking mechanism 3 are arranged side by side on the lower surface side. The cutting mechanism 2 has a so-called cutter knife structure, and includes a thin parallelogram-shaped cutting blade 4 with fold lines at appropriate intervals, and a metal holder 5 that holds the cutting blade 4 so as to be able to move forward and backward. ,
an operating body 6 slidably mounted on one side of the holder 5; and a cutting guide plate 7 extending obliquely forward and upward from the lower end of the front end of the holder 5 in an appropriate arc shape and made of an elastic material such as a steel plate. It is equipped with Note that the cutting guide plate 7 may be formed integrally with the holder 5 or formed separately and fixed thereto. As shown in FIG. 4, this cutting mechanism 2 has a holder 5 attached to a holder receiving part 8 having a substantially C-shaped cross section, which is provided along the longitudinal direction on the lower surface of one side of the grip main body 1.
is fitted in, and is fixed through the fitting or via a suitable set screw or the like. Further, as shown in FIGS. 3 and 4, the operating body 6 is formed with a spring receiving hole 9, into which a spring body 10 is inserted and held, and one side of the spring body 10 is It protrudes from a protrusion 11 opened at the side of the spring receiving hole 9, and resiliently contacts the side wall of the holder 5 so as to be relatively slidable. Further, as shown in FIGS. 1 and 3, an engagement protrusion 12 is provided on one side of the front end of the operating body 6, and the engagement protrusion 12 is connected to the insertion hole 13 of the rear end of the cutting blade 4. is inserted and engaged. And here,
By appropriately sliding the operating body 6 in the holder 5 against the elastic frictional force of the spring body 10, the cutting blade 4 can be moved in and out from the front end of the holder 5 along one side of the cutting guide plate 7. It is said that The marking mechanism 3 includes a loop 14 for marking the fabric, a support arm 16 that rotatably supports the loop 14 at its tip 15, and the support arm 1.
6, the case body 17 is attached to the lower surface of the other side of the grip body 1, the front upper part thereof has a gap S with the grip body 1, and the rear end side is attached and detached by a spring 18 etc. It is fixed freely. Further, a support shaft 19 having an axis in the middle part of the case body 17 in the lateral direction, that is, in the direction orthogonal to the direction in which the cutting blade 4 moves in and out.
The base end 20 of the support arm 16 is inserted into the case body 17 through the opening 21 on the front surface of the case body 17, and is inserted and supported by the support shaft 19. It is said that it is movable in the axial direction of 19. Further, the base end portion 20 of the support arm 16 is provided with a female screw portion 22 extending from the upper surface thereof to the support shaft 19, and is threaded through the opening portion 23 of the grip body 1 and the opening portion 24 of the case body 17. A fixing screw 25 is screwed into the female threaded portion 22, and the proximal end 20 of the support arm 16 and the support shaft 19 can be fixed and released through the screwing of the fixing screw 25. has been done. On the other hand, the loop 14 is located on one side of the protrusion of the cutting blade 4,
By moving the support arm 16 in the axial direction of the support shaft 19, the distance between the support arm 16 and the cutting 4 can be adjusted and fixed at an appropriate position. In addition, in Figure 2, 2
Reference numeral 6 denotes a marker, which makes it easier to adjust the distance between the cutting blade 4 and the lurette 14. Furthermore, the grip portion 27 in the rear half of the grip main body 1 may be appropriately configured to have an easy-to-grip shape.

The embodiment of the present invention is constructed as described above, and when it is used, the cutting blade 4 is made to protrude by an appropriate amount, the distance between the cutting blade 4 and the lurette 14 is set as the seam allowance, and then the cutting blade 4 is placed on the fabric. The fabric can be cut while running the lourette 14 along the pattern. In this way, the sewing line can be marked with the lure 14 at the same time as the fabric is cut, improving work efficiency. Also, when cutting the fabric with the cutting blade 4,
The elasticity of the cutting guide plate 7 made of an elastic material presses the fabric appropriately, allowing stable cutting. Furthermore, since the case body 17 of the marking mechanism 3 is supported on the rear end side and has a gap S with the grip main body 1 at the front upper part, the lever 14 side uses the rear end fixing part of the case body 17 as a fulcrum. It exhibits appropriate elasticity in the vertical direction and can prevent the loulette 14 from digging into the fabric.
Further, in adjusting the distance between the cutting blade 4 and the lurette 14, since the support arm 16 is configured to be movable along the support shaft 19, the distance can be selected steplessly, which is highly useful.

In the embodiment, the holder 5 for holding the cutting blade 4 is provided in the grip main body 1, but the cutting blade 4 may be provided directly on the grip main body 1 side so that it can be moved in and out. Well, it is not limited to the examples.

As described above, since the present invention is equipped with a cutting mechanism and a marking mechanism, it is possible to cut the fabric while marking the sewing line, resulting in high work efficiency. Further, the cutting guide plate made of an elastic material allows stable cutting, and the elasticity of the looplet prevents the looper from digging into the fabric. Furthermore, the adjustment of the distance between the cutting blade and the loop can be selected steplessly, providing the advantage of great utility.
