Description

【考案の詳細な説明】〔産業上の利用分野〕本考案は、クリツクロツク式スライドカツター
ナイフに関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a click-lock slide cutter knife.

[Conventional technology]

従来、この種のカツターナイフとして特開昭56
−139785号公報に掲載されたものが存在する。こ
のものは摺動駒の進退ノブを移動させて下に押す
ことにより、ロツク片を押し込んでロツク状態を
解除するようになつている。 Conventionally, this type of cutter knife was made in 1983.
-There is one published in Publication No. 139785. This device is designed to push in the lock piece and release the locked state by moving the advance/retreat knob of the sliding piece and pushing it downward.

従つて構造上摺動駒の高さが大きくなり進退ノ
ブがさやの外方に突出するため切断使用中手に力
が加わると進退ノブを押込んでしまい刃が不慮に
後退するおそれがある。又部品点数が多いので割
高となり組立作業に手数がかゝる等の欠点があつ
た。 Therefore, due to the structure, the height of the sliding piece is large and the advancing/retracting knob protrudes outward from the sheath, so if force is applied to the hand during cutting, there is a risk that the advancing/retracting knob may be pushed in and the blade may inadvertently retreat. Also, since there are a large number of parts, it is relatively expensive and has drawbacks such as requiring more time and effort to assemble.

〔考案の目的〕本考案は前記した従来の欠点を解消し、握り易
く、廉価にできるスライドカツターナイフを提供
することを目的とするものである。[Purpose of the invention] It is an object of the present invention to provide a slide cutter knife which is easy to grip and can be manufactured at low cost, by solving the above-mentioned conventional drawbacks.

This causes the blade 2 to protrude. Serrated engagement tooth rows 5, 5' are provided on the front upper and lower edges of the groove 3 to protrude from each other, and guide recesses 6, 6' are formed between the groove 3 and the engagement tooth rows 5, 5'. Elastic pieces 8, 8' equipped with protrusions 7, 7' that engage with both engagement tooth rows 5, 5' are integrally and parallelly protruded from the rear end of the synthetic resin sliding piece 9. The upper and lower ends of the moving piece 9 are loosely inserted into the guide grooves 6 and 6', and the sliding piece 9 is slid into the groove 3. As shown in FIG. 5, the sliding piece 9 has a horizontal guide groove hole 10 on the front side and a stopper piece 11 at the end thereof.
The rear surface is provided with a protrusion 12 into which the hole 2' at the rear end of the blade 2 is inserted. enters the guide slot 10 and expands the enlarged part 10' of the guide slot 10.
Both ends of the coil spring 15 housed in the protruding strip 14,
14', and a restraining protrusion 16 formed on one of the protruding pieces 14' is always positioned between the two protrusions 7, 7' due to the action of the coil spring 15, so that the protrusions 7, 7' are engaged. It is made so that it does not go beyond the tooth rows 5 and 5'. The lower end step part 1 of the guide groove hole 10 is attached to the protruding strips 14 and 14'.
Hooks 17 and 17' are formed to be hooked to the 0''.

[Effect]

コイルばね１５に抗して操作片１３を刃先を突
出させる方向に押すと、操作片１３はコイルばね
１５に抗して移動してストツパー片１１の位置で
止まり、従つて制止突部１６は突子７，７′の対
向位置より外れ突子７，７′は弾性片８，８′によ

１６が位置し外れるのを止めるようになる。 When the operating piece 13 is pushed against the coil spring 15 in a direction that causes the cutting edge to protrude, the operating piece 13 moves against the coil spring 15 and stops at the stopper piece 11, so that the stop protrusion 16 is pushed out. When the protrusions 7, 7' are removed from the opposing positions of the protrusions 7, 7', they can slide on the engagement tooth rows 5, 5' by means of the elastic pieces 8, 8', and the blade 2 can be advanced. Then, when you loosen your fingertips, the operation piece 13 returns to its original position due to the action of the coil spring 15, and the protrusions 7, 7'
When it engages with the engagement tooth rows 5, 5', the stopper protrusion 16 is positioned to prevent it from coming off.

[Effect of idea]

本考案によれば刃を繰出す構造が摺動駒と操作
片の２部材から成り立ち、全体の高さは低くでき
て取つ手兼用さやより突出しない。従つて切断使
用中に刃が不慮に後退するおそれはない。又部品
点数も少ないので組立も容易で低廉できる特長が
ある。 According to the present invention, the structure for feeding out the blade is made up of two members: a sliding piece and an operating piece, and the overall height can be made low so that it does not protrude beyond the handle sheath. Therefore, there is no risk of the blade accidentally retreating during cutting. Also, since there are fewer parts, assembly is easy and inexpensive.
