Description

[Technical field]

[0001] The present invention relates to a clip device for a writing implement that is capable of pulling out and retracting a clip relative to a barrel. [Background technology]

[0002] There is known a clip for a writing instrument that is retracted into the barrel when the writing instrument is in use so as not to interfere with the use of the writing instrument, or that protrudes from the barrel and can be hung in a clothing pocket, etc. Specifically, for example, a technology is known in which a clip is provided with a base portion that is movably introduced into the rear barrel in the radial direction of the rear barrel so as to be retractable, and a bent plate-like spring that imparts a spring force to the clip in the retracting direction, and the clip is protruded by a cam action or retracted by the spring force (see, for example, Patent Document 1).

[0010] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0011] 1 to 6, an example of the structure of the head side (opposite the writing tip) of writing instrument 100 is shown, which comprises a barrel 110, a clip 120, an elastic member 130, and a crown 140. Writing instrument 100 further comprises a writing body and the like housed inside barrel 110, but a description thereof will be omitted for convenience.

[0012] The barrel 110 has a barrel projection 112 in the shape of a square prism, and a notch 113 into which a clip 120 fits is formed on the writing implement head side of the barrel projection 112. A clip protrusion receiving hole 114 into which a protrusion 126 of a clip 120 described later fits is formed at a predetermined position of the barrel projection 112. A barrel top 115 into which a crown 140 fits is provided at the top of the barrel 110 on the head side. The barrel top 115 has a shape in which a part of the circumference is removed in cross section, and the upper end surface of the removed part extends to the writing implement tip side of the barrel body 111 to form a clip receiving step 116.

[0013] The clip 120 has a clip outer member 121 arranged on the outer periphery side of the shaft tube 110, a clip inner member 122 arranged on the inner periphery side, and an outer / inner member connecting portion 123 connecting the clip outer member 121 and the clip inner member 122. The clip inner member 122 is specifically composed of a pair of rod-shaped members 122a along the edge positions on both sides in the width direction of the clip. One end side of each rod-shaped member 122a is connected to the outer / inner member connecting portion 123, and the other end sides are connected to each other by an inner member connecting portion 124 (FIGS. 4 and 5). In addition, the clip outer member 121 or the outer / inner member connecting portion 123 has a recess 125 formed therein, the width dimension of which is set smaller from the clip outer member 121 toward the clip inner member 122 (FIG. 6). Furthermore, a convex portion 126 is formed on the inner surface side of the clip outer member 121 near the tip, and the clip convex portion receiving hole 114 is formed on the surface side of the barrel 110 at a position corresponding to the convex portion 126, so that the writing instrument 100 can be easily fixed when it is clamped in a clothing pocket or the like. Note that a concave portion may be formed instead of the clip convex portion receiving hole 114 as described above, and the clip convex portion receiving hole 114 of the barrel 110 and the convex portion 126 of the clip 120 do not necessarily have to be provided.

[0014] The clip 120 is inserted from the head side of the barrel 110, and with the outer / inner member connecting portion 123 fitted into the notch 113 of the barrel 110, a crown 140 (clip fixing member) is fitted to the barrel top 115 (Fig. 2). This prevents the clip 120 from slipping out of the head side of the barrel 110 while the clip outer member 121 is movable between a state in which it is in close contact with the barrel 110 and a state in which it is separated or pulled out (Figs. 2 and 3).

[0015] A lump-shaped elastic member 130 is provided between the inner periphery of the shaft tube 110 and the clip inner member 122 of the clip 120, so that the clip 120 is biased in a direction in which the clip outer member 121 comes into close contact with the shaft tube 110 (FIG. 5). The lump-shaped elastic member 130 is an elastic member formed of an elastic body that generates a biasing force by compressive strain caused by compressive stress, that is, a member that can expand and contract without structural deformation such as twisting or bending, such as a coil spring or a leaf spring. Such members are typically considered to be made of a solid material, but also include materials that are considered to be solid as a whole even if they contain fine bubbles, for example. The external shape of the elastic member 130 may be a rectangular parallelepiped, a sheet, or a long and thin wire corresponding to the shape of the rod-shaped member 122a, or it may be a deformable member such as a collection of spheres or a gel. More specifically, examples of the above-mentioned elastic member 130 include sponge-like members made of urethane, EPDM (ethylene propylene diene rubber), and silicone, and rubber sheets made of urethane, silicone, NBR (nitrile rubber), and fluororubber. In addition, sheets and felts made of elastomers can also be used.

[0016] As described above, the clip 120 can be moved between a retracted state and a pulled-out state relative to the barrel 110, so that it does not get in the way when writing or storing, and can be pulled out to function as a clip when needed, such as when clipping a pocket of clothing. Moreover, by generating the urging force that retracts the clip 120 by the lump-shaped elastic member 130 as described above, the clip can be easily retracted with a simple and compact configuration and pulled out when needed, and the length and thickness of the writing instrument 100 can be easily reduced. Moreover, the elastic member 130 as described above can be simply sandwiched between the barrel 110 and the clip inner member 122 of the clip 120, which also makes assembly easy.

[0017] (Other matters) In the above example, the clip inner member 122 is composed of a pair of rod-shaped members 122a, which makes it easy to secure the internal space (inner diameter) of the shaft tube 110 and keep the outer diameter small, but this is not limited to this, and the clip inner member 122 may be formed into a plate shape, etc., as long as it is possible to secure the internal space, etc.

[0018] In addition, the elastic member 130 can be made even more compact by forming it into an elongated shape corresponding to the rod-shaped member 122a. In addition, the thickness of the central part of the elastic member 130 in the width direction may be made relatively thinner than the side parts.

[0019] Furthermore, when the clip inner member 122 is composed of a pair of rod-shaped members 122a as described above, strength and rigidity can be easily ensured by connecting the ends of the rod-shaped members 122a with the inner member connecting portion 124, but if sufficient strength and rigidity can be obtained, the inner member connecting portion 124 does not necessarily have to be provided.

[0020] Furthermore, by forming recesses 125 in the outer and inner member connecting portion 123 etc. as described above, it is relatively easy to pinch or clamp the clip 120 with fingertips or nails and pull it out, but without being limited to this, it is also possible to make it easier to pinch the clip 120 by forming a chamfer on the edge of the clip outer member 121 on the shaft tube 110 side, by providing widthwise protrusions on the sides of the clip outer member 121 or the outer and inner member connecting portion 123, or by providing a recess on the side of the shaft tube extension portion 112.

[0021] In addition, when the clip 120 is inserted from the head side of the barrel 110, in order to prevent it from slipping out, a locking portion such as a convex portion and a concave portion may be provided at the contact portion between the clip 120 and the barrel 110 in place of or in addition to the cap 140 to prevent the clip from slipping out.

[0022] Moreover, the crown 140 is not limited to being fitted onto the barrel top 115, but may be screwed onto it. [Explanation of symbols]
