〔産業上の利用分野〕
この考案は時計ケースなどに設けて他の基板などの取付
板を支持するためのスナツプフィツト用柱に関するもの
である。[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a pillar for a snap fit that is installed in a watch case or the like to support a mounting plate such as another board.
従来のスナツプフィツト用柱は第１図の断面形状のよう
なものであった。A conventional snap fit post had a cross-sectional shape as shown in FIG.
すなわちケース１から２本のスナップピン２が突出し、
その先端部が支持すべき板３に設けた穴と係合するもの
である。In other words, two snap pins 2 protrude from the case 1,
Its tip engages with a hole provided in the plate 3 to be supported.
このスナツプフィツト用柱を形成するには第２図示のよ
うに成形製４．５を対向させて合成樹脂を流し込んでケ
ースとともに一体成形する。To form the pillar for the snap fit, as shown in the second figure, the molded parts 4.5 are placed opposite each other, synthetic resin is poured into them, and they are integrally molded together with the case.
〔考案が解決しようとする問題点〕
上記従来例においてはスナップピン２が長いので、これ
に対応して型４の突出部６およびこれと対向する型５の
突出部７，７が長いので、成形製のこれらの部分が強度
が弱くなるという欠点があり、また型４，５の接触面８
，８が広いのでかじりやすく、その部分に損傷が生じる
こととなり、ちらにそれにともない成製品にパリが出や
すい等の問題を生じていた。[Problems to be solved by the invention] In the above conventional example, since the snap pin 2 is long, the protrusion 6 of the mold 4 and the protrusions 7, 7 of the mold 5 facing it are correspondingly long. There is a disadvantage that the strength of these molded parts is weakened, and the contact surface 8 of the molds 4 and 5
, 8 are wide, so they are easily chewed, resulting in damage to those parts, which also causes problems such as cracks tending to appear on finished products.
この考案は、上面に平坦面を有する支持部からスナップ
ピンが突出する形状とすることにより、上記従来例にお
ける欠点を解決したスナツプフィツト用柱を提供するも
のである。This invention provides a column for a snap fit that solves the drawbacks of the above-mentioned conventional example by having a snap pin projecting from a support portion having a flat upper surface.
第３図〜５図を参照し本考案の一実施例を説明する。 An embodiment of the present invention will be described with reference to FIGS. 3 to 5.
ケース等のプラスチック酸の基板９から支持部１０が突
出している。A support portion 10 protrudes from a plastic acid substrate 9 such as a case.
この支持部１０は板から突出し先端には平坦面を有する
２本の半円柱状の柱１１．１１と両柱の先端部を互いに
連結する連結部１２とよりなっている。This support part 10 is made up of two semi-cylindrical columns 11, 11 that protrude from the plate and have flat surfaces at their tips, and a connecting part 12 that connects the tips of both columns to each other.
この支持部１２から一体に２本のスナップピン１３，１
３が互いに平行に突出形成されている。Two snap pins 13, 1 are integrated from this support part 12.
3 are formed protrudingly parallel to each other.
これらピン１３．１３にはっは状の係合突起１３ａが形
成されている。These pins 13.13 are formed with hook-shaped engagement protrusions 13a.
取付板１４にあけた穴に上記係合突起１３ａが突出し、
スナップピン１３，１３は取付板１４と係合し支持する
。The engagement protrusion 13a protrudes from the hole drilled in the mounting plate 14,
The snap pins 13, 13 engage and support the mounting plate 14.
このスナツプフィツト用柱の成形は型１５．１６により
なされるが、その場合スナップピン１３，１３を形成す
るための、型１５の突出部１７は、第２図の型４の突出
部６と比べて短く、また型１６の突出部１８．１８は第
２図示の対応する突出部７，７と比べて短くなっている
。This snap fit post is formed by molds 15 and 16, and in this case, the protrusion 17 of the mold 15 for forming the snap pins 13, 13 is larger than the protrusion 6 of the mold 4 shown in FIG. The projections 18.18 of the mold 16 are also shorter compared to the corresponding projections 7, 7 shown in the second figure.
第６〜８図を参照して、この実施例が上記実施と異なる
点は支持部６０の形状にあり、円筒部６１およびその先
端部の連結部６２よりなっている。Referring to FIGS. 6 to 8, this embodiment differs from the above embodiments in the shape of the support portion 60, which is comprised of a cylindrical portion 61 and a connecting portion 62 at its tip.
この実施例のスナツプフィツト用柱を成形するには型６
５．６６によりなされるが、この場合はさらに型同志の
接触部分が少くてすむ。To mold the snap fit post of this example, mold 6 is used.
5.66, but in this case, the number of contact parts between the molds can be further reduced.
本考案によるスナツプフィツト用柱によれば、ピンを支
持部の上に形成しているので、その分ピンの長さを短く
でき、これを形成するための成形製では、ピンを成形す
るための突出部を短くすることができ、型強度の向上を
はかることができる。According to the snap fit post according to the present invention, since the pin is formed on the support part, the length of the pin can be shortened accordingly, and the molding for forming the pin requires a protrusion to form the pin. It is possible to shorten the length of the mold and improve mold strength.
また成形室の突出部における接触面積を小さくできるの
で、いわゆるかじりが生じることが少く、またパリが出
ることも減らせるので型寿命を長くすることができる。Furthermore, since the contact area at the protrusion of the molding chamber can be reduced, so-called galling is less likely to occur, and the appearance of flakes can also be reduced, so the life of the mold can be extended.
