[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3196970 [Patent Document 2] Japanese Patent Application Laid-Open No. 2011-116031 Summary of the Invention [Problem to be solved by the invention]

[0004] The writing instrument disclosed in Patent Document 1 has stitching on the grip, which can make it difficult to hold. Furthermore, because the grip is made of leather, sweat generated during writing can slip between the hand and the leather, hindering comfortable writing. The writing instrument disclosed in Patent Document 2 does not have stitching on the grip, but the problem of slippage caused by sweat generated during writing remains.

[0005] In view of the above-mentioned problems, the present disclosure relates to providing a writing instrument that is easier to hold and allows for comfortable writing. [Means for solving the problem]

[0006] A writing instrument according to a first aspect of the present disclosure comprises a brush handle and a grip member attached to the portion of the brush handle that is gripped when writing, the grip member being made of seamless fabric formed into a cylindrical shape.

[0007] With this configuration, the grip member is made of seamless fabric, so there are no uneven areas at the sewn parts, which makes it easier to hold, and it can absorb sweat from the hands, making writing more comfortable.

[0008] A writing instrument according to a second aspect of the present disclosure is the writing instrument according to the first aspect of the present disclosure, wherein the seamless fabric is a knitted fabric.

[0009] With this configuration, the cushioning properties of the grip member can be improved and the amount of sweat absorption can be increased.

[0011] With this configuration, it is possible to obtain a grip member having characteristics that correspond to the properties of the thread used.

[0012] Furthermore, a writing instrument according to a fourth aspect of the present disclosure is a writing instrument according to the third aspect of the present disclosure, wherein the seamless fabric is made of a knitted yarn, the stitch size is 5 gauge to 14 gauge, and the yarn thickness is 630 denier to 1800 denier.

[0013] With this configuration, cushioning is ensured while the unevenness of the knitted fabric supports the fingers, improving ease of writing.

[0014] Furthermore, a writing instrument according to a fifth aspect of the present disclosure is a writing instrument according to any one of the first to fourth aspects of the present disclosure, in which an anti-slip means is provided on the surface of the brush handle at the portion where the grip member is attached.

[0015] This configuration can prevent the grip member from coming off the brush handle.

[0016] Furthermore, a writing instrument according to a sixth aspect of the present disclosure is a writing instrument according to any one of the first to fifth aspects of the present disclosure, wherein the cylindrically formed grip member has an anti-slip means on its inner surface.

[0017] This configuration can prevent the grip member from coming off the brush handle.

[0018] A writing instrument according to a seventh aspect of the present disclosure is the writing instrument according to any one of the third to sixth aspects of the present disclosure, wherein polyurethane is mixed into the thread.

[0019] With this configuration, polyurethane provides stretch and anti-slip properties, preventing the grip member from coming off the brush handle. [Effects of the Invention]

[0020] According to the present disclosure, the grip member is made of seamless fabric, so there are no steps at the sewn areas, which makes it easier to hold and also absorbs hand sweat, allowing for comfortable writing. [Brief explanation of the drawings]

[0022] Hereinafter, an embodiment will be described with reference to the drawings. In the drawings, identical or similar reference numerals are used to designate identical or corresponding components, and redundant explanations will be omitted.

[0023] [First embodiment] First, a writing instrument 1 according to a first embodiment of the present disclosure will be described with reference to FIGS. 1 to 3. FIG. 1 is a perspective view of the writing instrument 1. FIG. 2(A) is a front view of the writing instrument 1, and FIG. 2(B) is a right side view of the writing instrument 1. FIG. 3 is an exploded view showing the main components of the writing instrument 1. Although not shown, the rear of the writing instrument 1 is shown in the front view of FIG. 2(A) with the clip 16 removed, and the left side of the writing instrument 1 is shown symmetrically with respect to the right side view of FIG. 2(B). Hereinafter, the writing instrument 1 will be described as a mechanical pencil in this embodiment. In the following description, of the longitudinal ends of the writing instrument 1, the end from which the lead protrudes will be referred to as the "tip end," and the opposite end will be referred to as the "rear end." The writing instrument 1 comprises a brush handle 10 and a grip member 30.

[0024] In this embodiment, the brush handle 10 is a member formed into a cylindrical shape as a whole, and as shown in FIG. 3, includes a tip shaft 11, an inner shaft 13, an outer shaft 15, and a shaft ornament 17. The cylindrical brush handle 10 houses a mechanical pencil unit 21 (hereinafter simply referred to as the "mechanical unit 21") inside, has a stop ring 23 and a knock receiving cover 25 attached to the rear end, and a ferrule 27 attached to the front end. The ferrule 27 is a part that is sometimes called a cutter. The brush handle 10 is designed to house a lead (a mechanical pencil lead in this embodiment) inside via the mechanical unit 21.

[0025] Tip barrel 11 is a hollow, tubular member that constitutes the tip side of brush barrel 10. Tip barrel 11 is typically formed from brass into a hollow cylindrical shape, with threads formed on the outer surfaces of both ends of the cylinder. Tip barrel 11 is provided with a flange 12 that protrudes outward from the cylindrical outer surface at the boundary between the threaded and non-threaded portions on the rear end side. Flange 12 is typically provided over the entire circumferential length of cylindrical tip barrel 11. The extent to which flange 12 protrudes from the outer surface of tip barrel 11 is typically slightly smaller than the outer diameter of barrel ornament 17. The threaded portion on the rear end side of tip barrel 11, including flange 12, may be formed separately from the rest of tip barrel 11, with the two combined, or the two may be formed integrally.

[0026] Inner shaft 13 is a hollow, tubular member that constitutes the rear end side of brush handle 10. Inner shaft 13 is typically formed into a hollow cylindrical shape from polycarbonate (PC). Inner shaft 13 has a screw thread (not shown) formed on the inner surface of the tip side of the cylinder. The screw thread formed on the inner surface of inner shaft 13 on the tip side is adapted to mate with a screw thread formed on the outer surface of front barrel 11 on the rear end side. Inner shaft 13 also has a screw thread formed on the outer surface of the rear end side of the cylinder. The interior of inner shaft 13 has a portion (not shown) where the inner diameter is smaller toward the rear end than the center in the longitudinal direction.

[0027] The outer shaft 15 is a hollow, tubular member that fits around the outside of the inner shaft 13 so as to cover the inner shaft 13. The outer shaft 15 is typically formed into a hollow cylindrical shape from polycarbonate (PC). The outer shaft 15 is formed so that the inner diameter of the cylinder is substantially the same as the outer diameter of the inner shaft 13. Here, "the inner diameter of the outer shaft 15 and the outer diameter of the inner shaft 13 being substantially the same" strictly speaking means that the inner diameter of the outer shaft 15 is larger than the outer diameter of the inner shaft 13 to such an extent that the outer shaft 15 can slide longitudinally relative to the inner shaft 13, but the gap between the outer shaft 15 and the inner shaft 13 is as small as possible. In this embodiment, a clip 16 is attached to the outer surface of the outer shaft 15.

[0028] Ornament 17 is a cylindrical component disposed between front barrel 11 and inner barrel 13 and outer barrel 15. Ornament 17 is typically cylindrically formed from a metal such as stainless steel or ABS resin. In this embodiment, ornament 17 is formed so that the outer diameter of the cylinder is the same as the outer diameter of outer barrel 15, and the inner diameter of most of the cylinder is substantially the same as or slightly larger than the outer diameter of tsuba portion 12 of front barrel 11. Ornament 17 has an opening on the end face (hereinafter referred to as the "rear end face") on the rear end side of the cylinder that is sized to allow the threaded portion on the rear end side of front barrel 11 to pass through but not tsuba portion 12. With this configuration, when ornament 17 is fitted onto front barrel 11 from the rear end side of front barrel 11, the threads on the rear end side of front barrel 11 are exposed from the rear end face of ornament 17, while the rear end face does not move toward the tip from the position where it abuts tsuba portion 12.

[0029] Next, we will explain the components included in the writing instrument 1 according to this embodiment, other than the components that make up the brush barrel 10. The mechanical pencil unit 21 may have a known mechanical pencil mechanism, including a chuck mechanism that feeds and holds the lead, a lead guide connected to the chuck mechanism, and a long, tubular lead case that supplies the lead to the lead guide. In this embodiment, the mechanical pencil unit 21 has a portion (hereinafter referred to as the "enlarged diameter portion 22") with an increased outer diameter that houses a spring or the like, located closer to the rear end than the center in the longitudinal direction. The mechanical pencil unit 21 is sandwiched between the front barrel 11 and the inner barrel 13 by the enlarged diameter portion 22 being sandwiched between the rear end of the front barrel 11 and the inner barrel 13.

[0030] The retaining ring 23 is a cylindrical member that positions the outer shaft 15 by sandwiching it between itself and the shaft ornament 17. The retaining ring 23 is typically formed into a roughly cylindrical shape from a metal such as stainless steel or ABS resin. In this embodiment, the retaining ring 23 is formed so that the outer diameter at the front end is the same as the outer diameter of the outer shaft 15, and is tapered so that the outer diameter gradually decreases from the front end to the rear end. A thread (not shown) is formed on the inner surface of the retaining ring 23 to fit with the thread at the rear end of the inner shaft 13.

[0031] The knock receiving cover 25 is a cylindrical member attached to the rear end of the sharp unit 21. The knock receiving cover 25 is typically formed into a generally cylindrical shape from a metal such as stainless steel or ABS resin. The knock receiving cover 25 has an open end face on the front end side, with most of the interior being hollow, but the entire closed end face on the rear end side. This closed end face of the knock receiving cover 25 is adapted to receive knock operations from the user. The knock receiving cover 25 has a slightly rounded or chamfered shape from the closed end face on the rear end side to the outer surface. The inner diameter of the knock receiving cover 25 is slightly smaller than the cylindrical outer diameter of the rear end portion of the sharp unit 21. With this configuration, fitting the knock receiving cover 25 onto the rear end of the sharp unit 21 requires a force that overcomes the frictional resistance between them, and removing the knock receiving cover 25 from the sharp unit 21 requires a predetermined pulling force.

[0032] The ferrule 27 is a hollow, conical member that positions the grip member 30 between itself and the shaft ornament 17. The ferrule 27 is typically formed into a roughly hollow cone shape from a metal such as stainless steel or ABS resin. The outer diameter of the ferrule 27 gradually decreases from the rear end to the front end, and both end faces are open. The opening area of ​​the front end face of the ferrule 27 is smaller than the opening area of ​​the rear end face. The opening of the front end face of the ferrule 27 is large enough to allow the front end of the mechanical pencil unit 21 to pass through. The inner surface of the rear end of the ferrule 27 is formed with a thread (not shown) that fits with the thread formed on the outer surface of the front end of the front barrel 11. The ferrule 27 is screwed (threaded) to be detachable from the front end of the front barrel 11.

[0033] Next, the grip member 30 will be described. The grip member 30 is a member attached to the portion of the brush shaft 10 that is gripped during writing (the tip shaft 11 in this embodiment). In this embodiment, the grip member 30 is detachable from the tip shaft 11. The grip member 30 is a distinctive feature of the writing instrument 1 according to this embodiment, as will be described below. The grip member 30 is made of seamless fabric formed into a tubular shape. Here, seamless means that there are no stitches (seams) at the joints. The seamless fabric that makes up the grip member 30 can be a knitted fabric made by knitting yarn. The grip member 30 may be three-dimensionally knitted using a circular knitting machine. The grip member 30 is made of fiber, which allows it to have properties such as softness, comfort in the hand, cushioning due to its thickness, and sweat absorption. Furthermore, using seamless knitted fabric for the grip member 30 improves the appearance compared to a grip with stitches and eliminates disadvantages such as difficulty in holding due to the presence of unevenness that occurs when stitches are present.

[0034] The knitted fabric constituting the grip member 30 may be made of rib knitting. Rib knitting is a weft knitting structure in which ribs run vertically. Rib knitting generally has excellent horizontal stretchability and tends to be thicker than plain knitting. When the knitted fabric is made of rib knitting, the grip member 30 is stretchable in the horizontal direction (in this embodiment, the circumferential direction of the cylindrical shape). Therefore, by making the inner periphery of the cylindrical grip member 30 smaller than the outer periphery of the portion of the brush handle 10 to which the grip member 30 is attached, the grip member 30 can fit the brush handle 10 better. Polyester yarn can also be used as the yarn constituting the knitted fabric. The polyester yarn may be recycled yarn made from PET bottles. Constituting the grip member 30 from a knitted fabric using polyester yarn results in a grip member 30 that is excellent in durability and quick-drying properties. The stitches constituting the knitted fabric may be 7 gauge to 12 gauge, preferably 5 gauge to 14 gauge. Furthermore, the yarn constituting the knitted fabric may be 630 denier to 1275 denier, and preferably 750 denier to 1800 denier. By using yarn of such fineness (thickness), the cushioning properties of the grip member 30 can be improved.

[0035] The writing instrument 1 is constructed by assembling the above-mentioned components as follows. First, ornament 17 is fitted into tip barrel 11 from the rear end side of tip barrel 11. At this time, ornament 17 is fitted into tip barrel 11 from the side opposite the rear end face. When ornament 17 is fitted into tip barrel 11, flange portion 12 is housed inside ornament 17 and contacts the rear end face from the inside, so that the portion on which the threads are formed on the rear end side of tip barrel 11 is exposed further rearward than the rear end face of ornament 17. Next, the tip side of mechanical unit 21 is inserted into tip barrel 11 from the rear end side of tip barrel 11, and mechanical unit 21 is inserted into tip barrel 11 until enlarged diameter portion 22 of mechanical unit 21 contacts the end face on the rear end side of tip barrel 11. The order in which shaft ornament 17 and mechanical unit 21 are attached to front barrel 11 may be reversed, with mechanical unit 21 inserted into front barrel 11 and then shaft ornament 17 fitted in.

[0036] Next, inner shaft 13 is placed over front barrel 11 so as to cover the rear end side of mechanical unit 21 inserted therein, and the threads formed on the inner surface of inner shaft 13 are fitted into the threads on the rear end side of front barrel 11 exposed from ornament 17. As a result, ornament 17 is sandwiched between front barrel 11 and inner shaft 13, and enlarged diameter section 22 of mechanical unit 21 is sandwiched between the part of inner shaft 13 with a reduced inner diameter and front barrel 11, connecting front barrel 11 and inner shaft 13. Outer shaft 15 is fitted into inner shaft 13 of this connection body from the rear end side of inner shaft 13 so as to cover inner shaft 13, until the end face on the front end side of outer shaft 15 abuts ornament 17. At this time, the outer shaft 15 is movable in the longitudinal direction relative to the inner shaft 13, but with the outer shaft 15 placed over the inner shaft 13, the outer shaft 15 is positioned by screwing a retaining ring 23 onto the threads formed on the outer surface of the rear end of the inner shaft 13 protruding from the rear end of the outer shaft 15.

[0037] Once retaining ring 23 is attached to inner barrel 13, knock receiver cover 25 is attached to mechanical unit 21, which protrudes rearward beyond retaining ring 23. Knock receiver cover 25 fits onto mechanical unit 21 simply by inserting it into mechanical unit 21, and is designed not to fall off unless a pull-out force exceeding a predetermined magnitude is applied. Meanwhile, for the tip side of writing instrument 1, tubular grip member 30 is attached to tip barrel 11 from the tip side of tip barrel 11. At this time, by making the inner peripheral length of grip member 30, which is formed into a cylindrical shape by ribbing, smaller than the outer peripheral length of tip barrel 11, grip member 30 stretches in the circumferential direction and is attached to tip barrel 11, allowing grip member 30 to fit snugly (i.e., with a good fit) around tip barrel 11. Depending on the material and / or fineness of the thread used to make the seamless fabric, grip member 30 may have an oval or flattened shape in a cross section perpendicular to the axis rather than a circular shape before being attached to tip barrel 11; however, once attached to tip barrel 11, it adapts to the shape of tip barrel 11 and becomes circular. In other words, in this embodiment, grip member 30 becomes cylindrical when attached to tip barrel 11. When grip member 30 is attached to tip barrel 11, a threaded portion formed on the outer surface of the end portion on the tip side of grip member 30 protrudes from the tip side, and ferrule 27 is screwed into this portion. Writing instrument 1 is assembled in this manner.

[0038] In the writing instrument 1 configured as described above, the grip member 30, which is held when writing, is made of seamless knitted fabric. Since there are no stitches, the stitches do not come into contact with the hand, improving ease of holding. Furthermore, because the grip member 30 is made of knitted fabric, it can absorb hand sweat generated during writing, preventing slippage caused by hand sweat and allowing for continued comfortable writing. The sweat-absorbed grip member 30 can be removed from the brush shaft 10 by removing the ferrule 27 from the tip barrel 11. The grip member 30 removed from the brush shaft 10 can be washed, allowing the writing instrument 1 to be used in a clean state. Furthermore, if the grip member 30 is made of a knitted fabric made of polyester yarn, the washed grip member 30 can be dried quickly. Furthermore, if the grip member 30 is made of a knitted structure with a predetermined size of stitches using yarn of a predetermined thickness, the unevenness of the knitted fabric can support the fingers while ensuring cushioning, improving ease of writing.

[0039] Grip member 30 is not adhered to brush handle 10 with adhesive or the like so that it can be removed from brush handle 10 and washed. Nevertheless, as mentioned above, by making the inner periphery of cylindrical grip member 30 smaller than the outer periphery of tip barrel 11, the frictional resistance of the fibers themselves that make up the grip member 30 prevents it from slipping off brush handle 10. However, if you want to further improve the anti-slip effect of grip member 30 on brush handle 10, you may adopt the following configuration.

[0040] As shown in Fig. 4(A), anti-slip means 41 may be provided on the surface of front barrel 11 to which grip member 30 (see Fig. 1) is attached. Anti-slip means 41 may be formed by wrapping a rubber sheet or a resin sheet with a high surface friction coefficient around the surface of front barrel 11, by applying or coating the surface of front barrel 11 with an anti-slip agent, or by roughening the surface of front barrel 11 itself (in other words, by adding roughness).

[0041] Alternatively, as in the modified grip member 30A shown in Fig. 4(B), the inner surface may be provided with anti-slip means 42. As the anti-slip means 42, for example, rubber or resin may be attached in a dot pattern to the inner surface of the grip member 30A, as seen in anti-slip work gloves.

[0042] Alternatively, although not shown in the figures, a non-slip material (such as polyurethane) may be mixed into the thread that forms the seamless fabric that makes up the grip member 30, thereby imparting a non-slip effect to the grip member 30 itself. In order to mix a non-slip material into the thread, the non-slip material may be mixed in when the thread is spun, or a thread containing a non-slip material may be blended with a main thread (such as polyester thread).

[0043] [Second embodiment] Next, a writing instrument 2 according to a second embodiment of the present disclosure will be described with reference to Figures 5(A) and 5(B). Figure 5(A) is a perspective view of the writing instrument 2, and Figure 5(B) is a front view of the writing instrument 2. Although not shown, the back, left side, and right side of the writing instrument 2 appear substantially similar to the front of the writing instrument 2. "Substantially similar" means that the positions of the yarn connection points and gaps in the stitches of the knitted fabric, which will be described later, may not appear in exactly the same positions, but the other points are the same.

[0044] Writing instrument 2 differs from writing instrument 1 (see FIG. 1) in that outer barrel 35 is made of seamless fabric and formed into a cylindrical shape, instead of outer barrel 15 (see FIG. 1), which is typically made of polycarbonate (PC) and has a hollow cylindrical shape in writing instrument 1 (see FIG. 1). The seamless fabric constituting outer barrel 35 may be a knitted fabric made by knitting yarn. Outer barrel 35 may be made of the same material and by the same manufacturing method as grip member 30, or may be made into a structure different from grip member 30 by using the material and manufacturing method (including the size of the knitting) that may be used for grip member 30. The inner circumferential length of the cylindrical outer barrel 35 may be smaller than the outer circumferential length of inner barrel 13 (see FIG. 3) to which outer barrel 35 is attached, thereby improving the fit of outer barrel 35 to inner barrel 13. In addition to the outer barrel 35, the writing instrument 2 has a writing instrument barrel 10A that includes the tip barrel 11, inner barrel 13, and barrel ornament 17 shown in FIG. 3, which are the same as those of the writing instrument 1 (see FIG. 1). In the writing instrument 2, the outer barrel 35 is not provided with a clip 16 (see FIG. 1), but if a clip 16 is required, it may be attached to the retaining ring 23. In all other respects, the writing instrument 2 is the same as the writing instrument 1 (see FIG. 1), including the fact that the configurations of the modified examples (see FIGS. 4(A) and 4(B), etc.) can be applied.

[0045] In the writing instrument 2 configured as described above, the outer shaft 35 can be pulled out from the inner shaft 13 by removing the retaining ring 23 from the inner shaft 13. The outer shaft 35 removed from the inner shaft 13 can be washed. After washing, the outer shaft 35 can be attached to the inner shaft 13 and secured with the retaining ring 23, allowing the writing instrument 2 to be used in a clean state. Furthermore, since the outer shaft 35 can be repeatedly attached and detached from the inner shaft 13, washing the outer shaft 35 at appropriate intervals can keep the writing instrument 2 clean for an extended period of time. When attaching and detaching the outer shaft 35 to and from the inner shaft 13, by making the inner circumferential length of the cylindrical outer shaft 35 smaller than the outer circumferential length of the inner shaft 13 (see Figure 3), the frictional resistance of the fibers of the fabric that makes up the outer shaft 35 itself can prevent the outer shaft 35 from slipping relative to the inner shaft 13, even without adhesively bonding the outer shaft 35 to the inner shaft 13. However, if it is desired to further improve the anti-slip effect of outer shaft 35 relative to inner shaft 13, anti-slip means 41 (see FIG. 4(A)) applicable to grip member 30 described above may be applied to inner shaft 13. Alternatively, or in addition to this, anti-slip means 42 (see FIG. 4(B)) may be applied to outer shaft 35. Alternatively, or in addition to this, a material with an anti-slip effect (such as polyurethane) may be mixed into the thread that forms the seamless fabric that makes up outer shaft 35.

[0046] [others] In the above description, the seamless knitted fabric may be made of rib knitting. However, the knitted fabric may be made of pearl knitting to make the knitted fabric thicker and improve the elasticity when gripping the grip member 30 of the writing instrument 1, 2 and the outer barrel 35 of the writing instrument 2. Alternatively, the knitted fabric may be made of plain knitting to make the fabric thinner and improve the feel when gripping the brush shaft 10, 10A (especially the tip barrel 11).

[0047] In the above description, the seamless fabric is made using polyester thread. However, the seamless fabric may also be made using nylon thread. Alternatively, the seamless fabric may be made using cotton thread, linen thread, or paper thread to provide excellent sweat absorption, or wool or acrylic thread to provide heat retention. Furthermore, the seamless fabric may be made using rayon thread to provide a smooth feel. Alternatively, the seamless fabric may be made using functional fibers such as acrylic materials to provide moisture absorption and heat generation, or functional fibers such as rayon materials to provide a cool feel to the touch.

[0048] In the above description, the seamless fabric is a knitted fabric, but it may also be a woven fabric made by weaving threads.

[0049] In the above explanation, the writing instruments 1 and 2 are described as mechanical pencils, but they may be writing instruments other than mechanical pencils, such as ballpoint pens (oil-based or water-based), felt-tip pens, pencils, or brushes. Depending on the type of writing instrument, ink is stored inside the brush shaft instead of a lead. [Explanation of symbols]
