Description

  The present invention relates to a decorative round bar decorated with an embroidery thread.

  Conventionally, ribbon sticks and fishing rods used for rhythmic gymnastics have been decorated, and as one of the decoration methods, colored yarn is wound around a round stick portion of a ribbon stick or fishing rod. The ribbon stick is disclosed in Non-Patent Document 1 and Non-Patent Document 2, and the fishing rod is disclosed in Patent Document 1 and Patent Document 2.

  The decorations of the ribbon sticks described in Non-Patent Document 1 and Non-Patent Document 2 are those in which colored yarn is wound around an elongated truncated cone bar and the gradation effect of the wound colored yarn is used as a decoration. Further, the technology disclosed in Patent Document 1 provides “a decorative fishing tackle having a quaint and heavy appearance by firmly fixing a decorative belt-like body without using a large amount of thread-fastening paint and preventing its release. The solution to this problem is "A decorative pipe is attached to the outer peripheral surface of a fishing tackle formed by winding a reinforcing fiber prepreg sheet impregnated with a thermosetting resin around a cored bar and applying pressure and firing. The decorative pipe is formed by winding a decorative band-like body on the outer peripheral surface of a tubular body made of a synthetic resin in a spiral shape, and then performing thread fastening from the surface of the band-like body to an arbitrary length. It is formed by cutting into a. " The technique disclosed in Patent Document 2 has an object of "simplifying manufacturing work and providing a laminated tube having a large decorative effect in design." A high-intensity sheet of a predetermined length is provided on the outer periphery of the tube body, and a decorative winding layer in which a decorative thread or a decorative tape is wound spirally or in a spiral shape is provided on the outer side of the high-intensity sheet, and the outer side is translucent.

  However, in the ribbon sticks described in Non-Patent Document 1 and Non-Patent Document 2, since the twisted yarn is wound around the round bar, the surface has an uneven surface appearance and does not feel a refreshing deep color. In addition, the technique disclosed in Patent Document 1 winds a “decorative belt-like body” around a round bar, and this decorative belt-like body means “natural rattan, or synthetic material such as nylon, polypropylene, polyvinylidene chloride, etc. Because it is a “strip-shaped body having a similar appearance” (described in [0002]), the decoration is also large and suitable for the thick diameter of the hand part of the fishing rod, and the diameter of the tip of the fishing rod is a few millimeters It would be difficult to use on a stick. And in patent document 2, "the high-intensity sheet | seat is provided, and the decoration winding layer which wound the decoration thread | yarn or the decoration tape in the spiral shape or the twill winding form in the outer side of this high-intensity sheet | seat is provided." Therefore, the decorative thread or the decorative tape only plays the role of “preventing peeling and misalignment of the high-luminance sheet” (summary of the description in paragraph {0016}).

  Therefore, the present invention makes full use of the rich colors that the embroidery thread has, and has a beautiful gradation effect of reflected light and a hologram effect, so that the decorativeness is excellent and even the tip of the fishing rod is bent. In addition, an object of the present invention is to provide a decorative round bar that is excellent in wear resistance, chemical resistance, and durability without impairing the decorative properties.

In order to achieve the above object, a decorative round bar according to claim 1 of the present application is applied to a thin round bar having a smooth outer peripheral surface without twisting a flat surface of an embroidery thread having a flat cross section to the outer peripheral surface. The embroidery threads are tightly wound without being overlapped with each other, and a synthetic resin layer is formed by applying a transparent synthetic resin paint on the wound embroidery threads. The round bar includes a hollow tube and a solid tube, and also includes an elongated truncated cone-like rod whose diameter gradually decreases at a certain rate.
Further, a decorative round bar according to claim 2 is the decorative round bar according to claim 1, wherein the embroidery thread is held so as not to loosen in the round bar that rotates about a central axis. It is characterized in that it is fed and wound in a state where it is slightly tilted to the wound side from the direction perpendicular to the rotation axis of the round bar.
The decorative round bar according to claim 3 is the decorative round bar according to claim 1 or 2, wherein the diameter of the round bar is approximately 30 mmφ or less, and the width of the flat surface of the embroidery thread Is about 0.3 mm.
Further, a decorative round bar according to a fourth aspect is the decorative round bar according to any one of the first to third aspects, wherein the synthetic resin paint is an epoxy resin paint.

With the above configuration, the present invention has the following effects.
(1) Since the flat surface of the embroidery thread having a flat cross section is brought into close contact with the outer peripheral surface of the small-diameter round bar without being twisted, the embroidery thread is wound without overlap and without any gaps. By making full use of the abundant shades that are provided, the beautiful gradation effect of reflected light and the hologram effect can be obtained.
(2) When the embroidery thread is wound around a round bar that rotates around the central axis, the embroidery thread is held loosely and slightly wound from the direction perpendicular to the rotational axis of the round bar By maintaining the state inclined to the side, the embroidery thread can be in close contact with the outer peripheral surface of the round bar without being twisted without overlapping, and the embroidery thread can be wound around without any gap.
(3) By applying a transparent synthetic resin coating on the wound embroidery thread to form a synthetic resin layer, the embroidery thread is a round bar without interfering with the effects shown in (1) of the embroidery thread. It adheres firmly without unraveling.
(4) According to the applicant's knowledge, since the embroidery thread is easy to meander when the diameter of the round bar exceeds 30 mmφ, the meandering can be prevented by setting the diameter to about 30 mmφ.
(5) While it is considered that the decorative band-like body used in Patent Document 2 is several mm or tens of mm wide, the width of the flat surface of the embroidery thread used in the present invention is approximately 0. The thread width is 3 mm and the width is 1/10 or less. Therefore, the decoration is also elaborate and precise.
(6) By using an epoxy resin-based paint for the synthetic resin paint, the wear resistance, chemical resistance, and durability are increased, and the epoxy resin has flexibility even after curing. The horizontal direction of the embroidery thread having a flat cross section expands and contracts even when the round bar is bent, so that there is no gap between the embroidery threads and no swelling occurs.

FIG. 1 is a cross-sectional conceptual diagram showing a part of a longitudinal cross section in the length direction of a decorative round bar according to an embodiment. FIG. 2 is a conceptual plan view showing a part when the embroidery thread is wound around the round bar according to the embodiment.

  An embodiment according to a mode for carrying out the present invention will be described with reference to FIGS. 1 and 2. 1 and 2, reference numeral 1 denotes a decorative round bar according to the embodiment, reference numeral 10 denotes a round bar, reference numeral 20 denotes an embroidery thread, reference numeral 30 denotes a synthetic resin layer, reference numeral w denotes a thread width of the embroidery thread 20, reference numeral α is the crossing angle of the embroidery thread 20 with respect to the round bar 10, the one-dot chain line is the axis of rotation of the round bar 10, and the circular arrow is the direction of rotation of the round bar 10.

  First, the configuration of the decorative round bar 1 will be described mainly with reference to FIG.

  The decorative round bar 1 includes a round bar 10, an embroidery thread 20 that winds the surface of the round bar 10, and a synthetic resin layer 30 that is formed by being applied to the surface of the embroidery thread 20.

  The round bar 10 may be hollow or solid, and any material may be used as long as the surface is smooth, and the diameter is gradually and gradually reduced or expanded. It may have an elongated truncated cone shape. The diameter of the round bar 10 is optimally about 1 mmφ to 30 mmφ.

The embroidery thread 20 is of a commercially available flat cross section, and has a rich variety of colors, and a beautiful gradation effect of reflected light and a hologram effect are preferable from the viewpoint of decoration. The thread width (w) of the flat cross section is preferably 0.2 mm to 0.3 mm from the viewpoint of easy availability and handling, and the thread width (w) used in the examples is 0.26 mm. is there. Furthermore, the embroidery thread 20 is preferably a commercially available one wound around a cylindrical thread spool, and the reason will be described later.
The embroidery thread 20 is wound around the surface of the round bar 10 in a spiral shape so that the flat surface is in close contact with the surface of the round bar 10 and the embroidery thread 20 is in close contact with each other without overlapping.

  The synthetic resin layer 30 covering the surface of the embroidery thread 20 is formed by applying a transparent epoxy resin-based paint. By using a transparent epoxy resin-based paint, the abundant shades of embroidery thread are fully utilized, and the epoxy resin itself has wear resistance and chemicals without interfering with the beautiful gradation effect and hologram effect of reflected light. Effects such as resistance and heat resistance, and further, an effect of having flexibility after curing of the epoxy resin can be exhibited.

  Next, an example of a manufacturing process of the decorative round bar 1 will be described with reference to FIG.

(1) If necessary, the round bar 10 is sharpened with # 600 to # 800 ultra-fine water-resistant paper, the surface is polished and smoothed, and deposits such as oil and fat on the surface are removed. This work improves the adhesion of the embroidery thread 20 to the round bar 10.
(2) Temporarily fix the embroidery thread 20 to the round bar 10.
(3) While the round bar 10 is rotated about its central axis (in FIG. 2, it is rotated to the right when viewed from the right side of the figure), there is no slack and excessive tension (F) The embroidery thread 20 is sent out so as not to add. At this time, by setting the embroidery thread 20 to a state where the embroidery thread 20 is slightly inclined toward the wound side (α <90 °) from the direction orthogonal to the rotation axis of the round bar 10, the embroidery threads 20 do not overlap each other, and There will be no gaps.

Here, the “winding method that does not cause excessive tension on the embroidery thread 20” adopted by the applicant in the step (3) will be described.
(A) As the embroidery thread 20, a commercially available thread wound around a cylindrical spool is used. The bobbin is freely rotated through a round bar serving as a rotation shaft in the hollow part of the bobbin, and the yarn is fed out along the winding direction of the embroidery thread 20 (direction perpendicular to the cylindrical bobbin). Thereby, the embroidery thread 20 is not twisted. At this time, the tension (F) is set to be approximately 5N or less.
(A) The fed embroidery thread 20 leads at the fingertip. At this time, in order to prevent the embroidery thread 20 from being caught on the skin of the finger, work is performed with non-slip cloth gloves.

Following the above step (2),
(3) When the winding of the embroidery thread 20 is completed, the terminal portion of the embroidery thread 20 is temporarily fixed.
(4) The synthetic resin layer 30 is formed by applying and curing an epoxy resin-based paint on the wound embroidery thread 20.
Thus, the production of the decorative round bar 1 is completed.
