Fig. 1 is the overall longitudinal section of a tool of pen clip (the Network リ Star プ) mounting structure that represents to realize of the present invention tool.A tool 10 of this example is propelling pencil, but is not limited to this, goes for a tool arbitrarily such as ball pen.And this tool 10 possesses: front axle 11; Be threaded in the rear axle 12 of the rear end of front axle 11; Be threaded in the anterior end of pen part 14 of the front end of front axle 11; The anterior surrounding's tubular elastic clip that is located at front axle 11 is held portion 16; Be located at the core telescoping mechanism 18 as script main body in front axle 11.Core stretching structure 18 can be suitable for known structure arbitrarily, and the description thereof will be omitted.

The tail-hood 20 that is mounted parts as pen clip is installed in rear end at rear axle 12.Tail-hood 20 for example,, by synthetic resin material (, poly-acetic acid esters, ABS resin material) is formed to manufacture, is installed on the rear end of rear axle 12.Be installed under the state on rear axle 12 at tail-hood 20, roughly connect the inside of rear axle 12 as the core container 19 of the part of script main body, and the rubber that is arranged on the rear end of core container 19 bears platform 21 and gives prominence to from the rear end of rear axle 12 and tail-hood 20, bears platform 21 insert rubber at rubber.

Tail-hood 20 as shown in Figures 2 and 3, roughly has: the main body 20a that is installed on the ring-type of the outer peripheral face of the rear end of rear axle 12; Connecting portion 20b from from the outer peripheral face of main body 20a to external diameter Directional Extension; And be connected in the rear side of connecting portion 20b, and extend from the outer peripheral face of main body 20a the 20c of encirclement portion arranging to external diameter direction.

Main body 20a is as shown in Fig. 2 (d) and Fig. 2 (e), and side face forms the polygon portion 20d chimeric with rear axle 12 therein, and is formed with for the kick 20e chimeric with rear axle 12.In main body 20a, be pressed into the rear portion of rear axle 12, the front end of main body 20a and end difference 12a (Fig. 1) butt forming at the outer peripheral face of rear axle 12, the 20d of polygon portion is chimeric with polygon portion 12b (Fig. 1) of outer peripheral face that is formed at rear axle 12, and kick 20e is sticked in the outer peripheral face of rear axle 12, tail-hood 20 is fixedly mounted in rear axle 12.

Connecting portion 20b, as shown in Fig. 2 (c) and Fig. 2 (d), has the コ word shape 20f of portion that forms horizontal コ word shape cross section, the internal communication of the centre bore of main body 20a and the コ word shape 20f of portion.And, project laterally a pair of cylinder

axial region

20h, 20h from the two sides of the コ word shape 20f of portion.The upside of the jag of cylinder

axial region

20h, 20h becomes slightly by the shape of otch.

Be formed with continuously the 20c of encirclement portion at the rear portion of connecting portion 20b.The 20c of encirclement portion forms by being located at the first 20m of encirclement portion of main body 20a side and being arranged on the second 20n of encirclement portion that is arranged on pen clip component side than the first encirclement portion top side of 20m.

In more detail, shape when the first 20m of encirclement portion and the each leisure of 20n of the second encirclement portion are overlooked becomes, and inner peripheral surface is about semicircle arcuation separately, and outer peripheral face is about コ word shape, and direction each other becomes rightabout in front and back.Shape while merging thus the overlooking of the first 20m of encirclement portion and the second 20n of encirclement portion becomes, and inner peripheral surface is circle shape, and outer peripheral face becomes and connecting portion 20b all-in-one-piece rectangular shape.And the end of the first 20m of encirclement portion and the second 20n of encirclement portion コ word shape is separately interconnected with one another.In addition, the first 20m of encirclement portion and the second 20n of encirclement portion open portion 20m1,20n1 are separately located at a side respect to one another, and its direction is consistent with the projected direction of above-mentioned cylinder axial region respectively, consistent with the oscillation center axle of the pen clip parts 22 that the following describes.

Pen clip parts 22 roughly have pen clip board 22a and extend to the direction of rear axle 12 and tail-hood 20 the pen clip side plate 22b arranging respectively from the both sides of the edge of pen clip board 22a.On each pen clip side plate 22b, be formed with the receiving hole 22c that accepts above-mentioned each cylinder axial region 20h, and be formed with the slot part 22f being connected with receiving hole 22c.And, in the inside of pen clip board 22a, at the cyclic rib 22d that forms ring-type than receiving hole 22c by the position at rear.In addition, the rear portion of pen clip board 22a becomes the bend 22e protruding upward.

The cylinder axial region 20h of the tail-hood 20 by the chimeric correspondence of receiving hole 22c at pen clip parts 22, thus pen clip parts 22 are pivotably connected in tail-hood 20, and along the outside that is axially disposed in rear axle 12 of rear axle 12.And, because the upside of the jag of cylinder axial region 20h is by otch, and conjointly form slot part 22f with receiving hole 22c on pen clip parts 22, therefore when cylinder axial region 20h inserts receiving hole 22c, cylinder axial region 20h by otch moves to receiving hole 22c along slot part 22f, can successfully carry out this update.

Usually time for make pen clip parts 22 front end pushing rear axle 12 surface and thus between produce clamping force, between pen clip parts 22 and tail-hood 20, insert helical spring 24, helical spring 24 is configured in than connecting portion 20b by rear, to the direction reinforcing that tail-hood 20 and pen clip parts 22 are become estranged.

Helical spring 24 is surrounded by the 20c of encirclement portion of tail-hood 20 by its one end, and its other end inserts in the cyclic rib 22d of pen clip parts 22, thereby is configured between tail-hood 20 and pen clip parts 22.The besieged 20c of portion in two ends of helical spring 24 and cyclic rib 22d constraint.

In more detail, the first 20m of encirclement portion surrounds at least one aspect side of the end of helical spring 24, opened the remainder of the end of helical spring 24 by open portion 20m1, the second 20n of encirclement portion surrounds the side at least on the other hand of the end of helical spring 24, by the remainder of the end of the open helical spring 24 of open portion 20n1, become the all-round of the end that utilizes the first 20m of encirclement portion and the second 20n of encirclement portion to surround helical spring 24.

At pen clip mounting structure as constructed as above, utilize helical spring 24, usually time, as shown in Fig. 5 (a), the front end of pen clip parts 22 is to the direction reinforcing of pushing rear axle 12.And, between pen clip parts 22 and rear axle 12, sandwich the occasion of article, the bend 22e of the rear end of pressing pen clamp assembly 22, pen clip parts 22 are resisted the active force of helical spring 24 and are swung, between the front end of pen clip parts 22 and rear axle 12, open, thereby can insert article to this gap, and utilize both to clamp article.

The height of the 20c of encirclement portion and cyclic rib 22d preferably in the time that pen clip parts 22 swing, the height of mutual hands-off degree.Owing to utilizing the 20c of encirclement portion to surround to a certain extent a helical spring end, thereby the lower member of height of cyclic rib 22d can be set.

Like this, due to helical spring 24, the besieged 20c of portion surrounds, thereby can prevent reliably coming off of helical spring 24, and because the 20c of encirclement portion can surround quite a few of helical spring 24, thereby can suppress to expose to outside as the helical spring 24 of machine components, can make profile good.And because bending has bend 22e, thereby become the shape that is more difficult to see helical spring 24.

And, by forming the 20c of encirclement portion by the first 20m of encirclement portion and the second 20n of encirclement portion, thereby can easily possess the shaping of the tail-hood 20 of the 20c of this encirclement portion itself.Fig. 6 is its key diagram, part 20m1, the 20n1 of the first 20m of encirclement portion and the second 20n of encirclement portion opening are separately toward each other, therefore the slide block S1, the S2 that are shaped for the part 20m1 to this opening, 20n1 can be by being equivalent to the part of this open portion 20m1,20n1, and approach towards each other the direction separating and move.

Especially, because the first 20m of encirclement portion is consistent with the projected direction of cylinder axial region 20h with the direction of part 20m1, the 20n1 of the second 20n of encirclement portion opening separately, therefore can utilize identical slide block S1, S2 to form cylinder axial region 20h and the 20c of encirclement portion, do not need to make mould to become complicated, can easily be shaped.Because the cylinder axial region 20h of connecting portion 20b also gives prominence to opposition side each other in two side direction, therefore for these are cut to partially-formed slide block S1, S2 according to cylinder axial region 20h heavy, need to approach towards each other the direction separating and slide from forming in the both sides of part of cylinder axial region 20h.

And, because the 20c of encirclement portion and connecting portion 20b form continuously, therefore can dwindle the overall dimensions of pen clip mounting structure.

In addition, because helical spring 24 is disposed in the outside of rear axle 12 and tail-hood 20, thereby can effectively utilize the inner space of rear axle 12 and tail-hood 20, this occasion, because connecting rear axle 12, core container 19 arranges, the length that can guarantee core container 19 is large, and can supplement core from the rear of a tool 10 to core container 19.

And in above-mentioned example, encirclement portion is formed at as pen clip and is mounted on the tail-hood 20 of parts, but is not limited to this, also the beam barrel that is called rear axle or front axle can be mounted to parts as pen clip.

In addition, in above-mentioned example, encirclement portion is located at pen clip and is mounted on parts, but is not limited to this, also encirclement portion can be located on pen clip parts, also can be located at pen clip and be mounted parts and pen clip parts both sides.

And in above-mentioned example, the connecting portion that is mounted parts at pen clip forms axial region, forms receiving hole at pen clip parts, but on the contrary, the connecting portion that is mounted parts at pen clip forms receiving hole, forms axial region also can at pen clip parts.Or, form axial region at the connecting portion of pen clip parts, form receiving hole at the connecting portion of pen clip parts and also can.No matter which kind of situation, make the first encirclement portion and the direction of the part of the opening of the second encirclement portion and the hole of receiving hole axially or the projected direction of axial region consistent, be shaped and become easy and suitable.In addition, although applicable encirclement portion and connecting portion form continuously, be not limited to this, encirclement portion and coupling part are liftoff, and formation is also passable.
