Description

  The present invention relates to a tool for forming a shed in a hand loom or the like.

2. Description of the Related Art Conventionally, a jig having a configuration in which a warp is passed through a hole provided in each of a plurality of thin rod-like hooks arranged side by side, a predetermined warp is pulled up by pulling up a predetermined hook, and a hook is formed between the warps. Has been used. However, in recent years, as a simple tool that is easy to handle instead of such a tool, a plurality of groove portions are arranged in parallel in the longitudinal direction of the rod-shaped tool, and the groove portion is vertically moved as the tool rotates. Have been developed to form a shed between the warp yarns by turning up and down the warp yarns that are hung on each groove portion (Patent Document 1, Patent Document 2, Patent Document 3).
However, any of these simple types of tools are inferior in production efficiency due to usage problems such as the warp coming off from the groove during use, the warp not moving up and down smoothly, and its complicated configuration. However, there are problems such as difficulty in mass production and limitations on the shape of the tool that can be manufactured.
Japanese Utility Model Application Publication No. 62-20460 JP 2001-98441 A Japanese Patent No. 3684167

  Therefore, the present invention is the simple type tool, which is easy to warp, can securely hold the warp without detaching or shifting during use, and smoothly moves up and down adjacent warps. Another object of the present invention is to provide an apparatus capable of easily forming an appropriate shed appropriately and capable of warping a thin thread with high density, which can be easily mass-produced.

In this invention, the said subject was solved by connecting and manufacturing the unit which can integrally mold a collar part main body.
That is, the saddle tool of the present invention is used on the frame of a hand loom, and the saddle body has a plurality of semi-cylindrical units each having a substantially inverted U-shaped end surface, and is adjacent to the saddle tool body. The inverted U-shaped end faces of the unit are connected to each other,
The wall of the unit has a plurality of slits passing through the ceiling, and one slit extends from a depth X on the near side of the ceiling to a depth Y on the back side of the ceiling, The adjacent slits are provided in a comb-teeth shape in which the depth increases and decreases from the depth X on the back side of the ceiling portion to the depth Y on the near side of the ceiling portion,
Both ends of the collar main body to which the unit is connected are fixed to a support that can be used with the unit tilted forward and backward on the frame.

  Such a jig of the present invention is arranged so that the left and right vertical frames of the main body of the hand loom having a warp unwinding shaft and a warp (or woven fabric) winding shaft before and after the frame are orthogonal to the vertical frame. By installing, the warp can be easily warped between the unwinding shaft and the winding shaft, simply by fitting it into the slit of the buttock main body, and then by simply tilting the support tool back and forth, The heights of the warps fitted in the slits can be changed with each other, and a shed can be formed between the warps. ,

  The support may be used by being indirectly mounted on the frame of the hand loom, but it has an inverted trapezoidal part below, and the both ends of the buttock main body to which the unit is connected, The bottom of the inverted trapezoidal portion is placed on the frame body by fixing it so as to be positioned at the center of the inclined surface of the inverted trapezoidal portion of the support so that it is located at the center of the support, By simply moving back and forth so that the front and rear slopes are alternately in contact with the frame body, a shed can be formed, which makes it very easy to handle.

  In the present invention, a plate-like portion that protrudes downward from the lower end of the inverted trapezoidal portion outside the support provided at the end of the collar body is orthogonal to the base of the inverted trapezoidal portion. By providing it to the vertical frame of the hand loom body, the inverted L-shaped cross section formed between the bottom surface of the inverted trapezoidal part and the plate-like part can be surely adapted, so that the operation of the tool is more stable Can be implemented.

  Further, in the present invention, a convex portion and a concave portion are provided on the opposite U-shaped end faces of the unit, and the convex portion of one unit is fitted into the concave portion of the adjacent unit so that the adjacent units are closely connected. It is preferable to do so.

  The buttock main body constituted by connecting such units needs to be fixed to the support in a state where it can be stably operated. The fixing method is not particularly limited. For example, the lower end portion of each unit is formed in a cylindrical shape, a rod is passed through a hole in the cylindrical portion, the unit is connected, and the rod is fixed to a support. May be.

  The slits formed in the unit are formed to have different depths on the near side and the back side of the ceiling of the unit, and the depths are alternately different for each adjacent slit. This ensures the formation of a shed between the warps during weaving. Depth (distance from the top of the unit 2 to the bottom surface of the slit 4) The ratio of X and Y may be about 1: 2 to 1: 6, particularly about 1: 3 to 1: 5.

  Since such a unit can be easily formed by plastic molding, the unit can be formed in advance, and the units can be connected to each other according to the size of the main body of the hand loom, and can be formed into a brace. In addition, mass production becomes possible.

The number of slits provided in one unit is usually about 3 to 30, and preferably about 5 to 15. Moreover, the width of the slit may be appropriately selected depending on the thickness of the yarn to be used, the weave density, etc., but in the present invention, a slit product having a narrow width of about 0.4 to 1.5 mm, particularly 1.0 mm or less. Can be stably supplied.

  In the present invention, the substantially inverted U-shape means one that functions in the same manner as the U-shape, and is not only a pure U-shape, but also a symmetrical hollow mountain shape, It includes an arc shape or a shape obtained by crushing it.

  Since the jig of the present invention can be manufactured with an assembled structure, it is very easy to handle in any of manufacturing, transportation and storage. In particular, the unit can be plastic-molded with a relatively small mold, and it is economical because it can arbitrarily form a buttock body of a desired length by connecting it, and it consists of very fine slits The product can be manufactured stably.

Next, the present invention will be described according to embodiments shown in the drawings.
In the example of FIG. 1, the collar body 1 is formed by connecting a semi-cylindrical unit 2 having a substantially inverted U-shaped end face to the left and right. A plurality of slits 4 passing through 3 are provided. The one slit 2 extends from a depth X on the near side of the ceiling part 3 to a depth Y on the back side of the ceiling part, and a slit adjacent to the slit 2 has a depth X on the back side of the ceiling part. In the state where it extends to the depth Y on the near side of the ceiling part, the depth is provided in a comb-teeth shape that goes up and down,
Both ends of the buttock main body 1 to which the unit 2 is connected are fixed to a support 5 that can be used with the unit 2 tilted forward and backward on the frame 13 of the hand loom. In this example, the support 5 has an inverted trapezoidal portion 6 on the lower side, and both end portions of the collar body 1 are in the vicinity of the upper end of the inclined surface of the inverted trapezoidal portion 6 at the center of the support 5. It is fixed so that it is located.
In this example, a plate-like portion 7 protruding downward from the lower end of the inverted trapezoidal portion 6 is provided outside the support 5 so as to be orthogonal to the bottom side of the inverted trapezoidal portion 6. An L-shaped cross-sectional portion formed between the bottom surface of the inverted trapezoidal portion and the plate-like portion can be used by being fitted into the vertical frame of the hand loom body.

  Next, another example is shown in FIGS. In this example, a convex portion 8 and a concave portion 9 are respectively provided on the inverted U-shaped end surface of the unit 2, and the adjacent unit 2 is connected by fitting the convex portion 8 and the concave portion 9 of the adjacent unit 2. The lower end of the unit 2 is formed in a cylindrical shape, and the unit 2 is connected to the hole 11 of the cylindrical portion 10 through the rod 12, and the rod 12 is attached to the support 5. It is designed to be fixed (see FIG. 4).

  Each unit 2 is provided with 11.5 slits 4 each having a depth (distance from the top of the unit 2 to the bottom surface of the slit 4) X: Y ratio of 1: 4.5. In this example, the width of the slit 4 is 0.8 mm.

Further, in this example, one slit 4 can be formed on the left and right end surfaces of each unit 2 by being connected to the adjacent unit 2. For example, the short side end (depth X) of the slit 4 is formed by connecting the adjacent units 2 on the near side of the ceiling part 3, and the long side end of the slit 4 is formed on the back side of the ceiling part 3. A portion (depth Y) is formed. Here, the convex portion 8 and the concave portion 9 provided on the inverted U-shaped end surface of the adjacent unit 2 are fitted, and at the same time, the unit 2 is short. The joining surfaces of the end surfaces 14a and 14b where the end portions (depth X) are formed are joined with an adhesive to ensure the formation of the slit 4 between the units 2 (see FIGS. 2 and 3). .

  In addition, both ends of the collar body 1 formed by connecting the units 2 are attached so as to be positioned in the center of the support 5 near the upper end of the inclined surface of the inverted trapezoidal portion 6 of the support 5. A plate-like portion 7 projecting downward is provided outside the support 5 so as to be orthogonal to the bottom side of the inverted trapezoidal portion 6, and an inverted L formed by the bottom side of the inverted trapezoidal portion 6 and the plate-like portion 7. The character-shaped cross-section portion can be used by fitting it into the frame of the hand loom body (see FIGS. 3 and 4).

  Such a saddle tool of the present invention is such that the bottom surface of the inverted trapezoidal portion 6 of the support tool 5 is placed on the frame of the hand loom main body, and each slit 4 of the hook body is hung from the front side to the back side or from the back side to the front side, After the warping, the inverted trapezoidal portion 6 of the support 5 is alternately turned over so that the front and rear slopes 15a, 15b are positioned on the frame, so that the slit 4 on the opposite side to the side that has been turned over is high. Only the warp located on the bottom surface (depth X) can be lifted, and the shed can be easily formed, so that weaving with good quality can be easily performed.
