Description

【０００１】
【発明の属する技術分野】
本発明は、例えば複数の筒体が順次多重に嵌り合い、夫々が互いに伸縮スライドして全体長が可変するように構成され、内法定規として使用することができる伸縮式箱尺に関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
従来の伸縮式箱尺は、所定の目盛を付した径大な筒体に所定の目盛を付したやや径小な筒体を引き出しスライド自在に嵌挿し、三重合タイプでは更にやや径小な筒体を引き出しスライド自在に嵌挿した構成で、例えば内法を測定する場合は、夫々を順次引き出して測定部間に架設し、所定の指示位置での目盛を読むことで全体長を内法として測定できるように構成している。
【０００３】
また、各筒体は係止機構により最大引き出した位置が係止保持されるように構成すると共に、引き出し途中位置であってもこの位置を固定して全体長を固定保持できるように各筒体に締め付けネジ機構を設けている。
【０００４】
従って、この締め付けネジを締め上げることで最大に引き出した係止位置を固定ロックできると共に、引き出し途中の筒体も測定位置で固定ロックできるため、測定した状態をこの締め付けネジにより固定保持してから持ち運び、この測定した内法との過不足を見ることができるなど非常に便利である。
【０００５】
しかし、この締め付けネジは容易に設けることはできるものの、確実に固定保持されているか否か、つまり十分に締め上げられて筒体が移動不能な状態に固定ロックされているかどうかを視認することができない。
【０００６】
そのため、まだ締め付けていないのに測定位置から持ち運んでしまったり、締め付けが不十分なためにロックしたはずの全体長が筒体の移動により狂ってしまったりする場合がある。
【０００７】
また、内法を測定した状態でロックする際、締め付けネジを回し操作しなければならないため、確実に誤差なく所定の位置で素早く固定することも容易ではない。また、ネジにより筒体を傷めるおそれもある。
【０００８】
本発明は、このような問題点を見い出しこれを解決したもので、簡易な構成でネジ回し操作を行わなくても、ワンタッチで測定位置（測定時の全体長）を固定ロックでき、またその解除もワンタッチで行え、しかも確実にロックされているか否かを一見で視認でき、また更にこの固定ロック機構も最大引き出し位置係止機構と合せて容易に製作することも可能で、量産性も劣らず容易に実現可能な画期的な伸縮式箱尺を提供することを目的としている。

【００１２】
また、前記径大な筒体１に内装し、且つ前記径小な筒体２に被嵌し、前記径大な筒体１の基端部寄りに設けた回動操作ハンドル３を位置決め固定する位置決め部９を設け、この位置決め部９に前記径小な筒体２の端部に設けた係止部10に着脱自在に係止する最大引き出し位置係止保持用の係合部11を設け、前記径大な筒体１に対して前記径小な筒体２を最大に引き出した際に前記係止部10と前記係合部11とが係止して位置決め保持されるように構成したことを特徴とする請求項１，２のいずれか１項に記載の伸縮式箱尺に係るものである。

【００１６】
【発明の実施の形態】
好適と考える本発明の実施の形態（発明をどのように実施するか）を、図面に基づいてその作用効果を示して簡単に説明する。
【００１７】
相対的に径大な筒体１に対して径小な筒体２を所定長引き出したところで、回動操作ハンドル３を起伏回動（所定方向に回動操作）することで圧接部４が径小な筒体２に圧接して、この筒体２の径大な筒体１に対するスライド移動が不能となり、この引き出し位置で固定ロックされることとなる。
【００１８】
従って、例えば回動操作ハンドル３を筒体１の外面上で略１８０度起伏回動することで、圧接部４の圧接による固定保持と圧接解除が切り替えられるように設定すれば、この回動操作ハンドル３の回動位置を見るだけで、全体長が固定ロックされている状態か否かを一見で視認できることとなる。
【００１９】
また、この回動操作ハンドル３を、径大な筒体１に内装され、且つこの筒体１内に挿通する径小な筒体２に被嵌する被嵌部５に軸着して径大な筒体１の外面で起伏回動するように構成すれば、容易にこの回動操作ハンドル３を設けることができ、また、この回動操作ハンドル３を設ける被嵌部５の左右に同様に被嵌する位置決め部９を設けることで容易にして確固に回動操作ハンドル３を位置決め固定できるし、この位置決め部９に径小な筒体２の端部に設けた係止部10と着脱自在に係止する最大引き出し位置係止保持用の係合部11を設けることで、最大引き出し位置で自動係止する係止機構も容易に設けることができることとなる。
【００２０】
【実施例】
本発明の具体的な実施例について図面に基づいて説明する。
【００２１】
本実施例は、方形筒状の三つの筒体が互いにスライド突出自在に三重に嵌り合い、各筒体を順次引き出すことで全体長を伸長できるように構成した三重構成の伸縮式箱尺に本発明を適用したものであって、各筒体には所定の指示位置でその全体長を読み取ることのできる目盛が付されており、測定部に外端部を当接させて架設した際この目盛を読むことで内法を測定できるように構成している。
【００２２】
勿論、本発明は本実施例に限られず、径大な筒体と径小な筒体の嵌挿数は、一つでも本実施例のように二つでも、あるいはそれ以上でも良く、また目盛を読むのではなく、デジタルカウンタにより全体長がデジタル表示されるように構成しても良い。
【００２３】
本実施例では、相対的に各径大な筒体１と径小な筒体２との各嵌挿構造に、夫々引き出し位置固定機構と、最大引き出し位置係止機構とを設けた構成で、以下この構造について詳述する。
【００２４】
本実施例では、径大な筒体１内に嵌合状態に内装され、且つ前記径小な筒体２に被嵌し得る被嵌部５の上部に回動操作ハンドル３を軸着し、このハンドル３の先端部を操作部とし基端部を圧接作用部として構成した固定用操作部６を、前記径大な筒体１に設けた取付孔７からこの筒体１内に落とし込み内装して、この固定用操作部６の回動操作ハンドル３を回動することで圧接作用部によって押し付けられる板状の介在スペーサとして被嵌部５内側に設けた圧接部４が、この固定用操作部６に挿通している前記径小な筒体２に圧接してこの筒体２がその操作位置で締め付け固定されるように構成している。
【００２５】
即ち、本実施例の被嵌部５は、上部が開口したコ状部材で構成し、この被嵌部５の上端部に回動軸８を架設し、この回動軸８に前記回動操作ハンドル３を起伏回動自在に枢着して前記固定用操作部６を構成し、この固定用操作部６を前記径大な筒体１に設けた取付孔７を介して落とし込み内装して前記回動操作ハンドル３をこの筒体１の外面より突出状態にして長さ方向に１８０度切り替え反転自在に配設し、この固定用操作部６の被嵌部５に板状の圧接部４を介在させ、前記径大な筒体１に挿通した前記径小な筒体２を挿通配設し、前記回動操作ハンドル３の基端部の圧接作用部によって前記被嵌部５内に配設した圧接部４が前記径小な筒体２に面接してこの筒体２を確固にして傷つけることなく締め付け固定できるように構成している。
【００２６】
従って、一方側へ回動操作ハンドル３を倒せば、圧接は解除され筒体２をフリーに引き出しスライドでき、反対側へ倒せば、圧接して締め付けることになり、被嵌部５が取付孔７により筒体１に係止固定されているため、筒体２のスライド移動は阻止され、固定ロックされることとなる。
【００２７】
故に固定ロック解除は、この回動操作ハンドル３の反転回動操作によってワンタッチで行え、この回動操作ハンドル３が所定側に倒すか否かによって確実にこの切り替えが行え、しかもこの倒してある方向によって一目でロック状態か否かが判断できることとなる。
【００２８】
また、前記径大な筒体１に嵌合状態に内装し、且つ前記径小な筒体２に被嵌し、前記径大な筒体１の基端部寄りに設けた回動操作ハンドル３を位置決め固定する位置決め部９を設け、この位置決め部９に前記径小な筒体２の端部に設けた係止部10に着脱自在に係止する最大引き出し位置係止保持用の係合部11を設け、前記径大な筒体１に対して前記径小な筒体２を最大に引き出した際に前記係止部10と前記係合部11とが係止して位置決め保持されるように構成している。
【００２９】
即ち、本実施例の位置決め部９は、前記固定用操作部６の被嵌部５を境にしてその左右に分離して配設されるように構成し、この各左右の位置決め部９は、前記径小な筒体２に被嵌した状態で前記径大な筒体１に設けた係止孔13に夫々凸部を係止させてこの左右の位置決め部９の間の前記固定用操作部６の回動操作ハンドル３を位置決め固定するように構成し、この一方の位置決め部９に前記最大引き出し位置係止保持用の係合部11を設けている。
【００３０】
更に説明すれば、前記各位置決め部９は、夫々上下に分離した二つ一組構成とし、各上下に分離した部材が夫々径大な筒体１の各係止孔13に凸部を係止して位置決められ、この左右の各位置決め部９によりその中間の被嵌部５が更に位置決められて、回動操作ハンドル３が固定されるように構成している。
【００３１】
このように分離した構成とすることで組み付け易く、特に一方の奥側の位置決め部９を上下に分離しているため、この装着時に空孔となっている係止孔13を越えて奥の係止孔13に係止させなければならないが、これも容易に行えることとなる。
【００３２】
また、この一方の位置決め部９は、上下の分離した部材の対向端部に夫々切り欠きが形成され、これが略突き合い近接することで開口縁を有する前記係合部11が形成されるように構成している。また、他方の位置決め部９は筒体２の端縁に係止している。
【００３３】
また、この係合部11に着脱自在に係合する前記係止部10は、やはり同様に上下に分離した構成で互いに径小な筒体２の端部に被嵌し、径大な筒体１内に内装すると共に、筒体１に設けた係止孔13に凸部を係止して固定され、この被嵌部材に係止突起部10Ａを設け、この係止突起部10Ａに係止凸部10Ｂを設けて係止部10を構成し、この係止突起部10Ａが径小な筒体２に設けた逃げ孔14によって撓み可動し得るように構成し、この係止部10の係止凸部10Ｂが係止突起部10Ａの撓み復帰弾性によって、丁度位置決め部９と係止部10との端同志が突き当たる最大引き出し位置に引き出した際、前記係合部11に着脱自在に係止するように構成している。
【００３４】
また、前記径大な筒体１及び前記径小な筒体２の外端部にこの筒体１，２の幅より長く突出した突き当て端部部材12を付設し、この左右の突き当て端部部材12の突出部の外側面を例えば図３に示すように測定面に当接することで、この突き当て端部部材12の突出長により前記径大な筒体１及び前記径小な筒体２が前記測定面の当接部間から離れた状態に配設できるように構成している。従って、図３に示すように、例えば当接部（測定部）間に出っ張りや柱などがあってもこれを避けつつ内法を測定できることとなり、非常に実用性に秀れる。
【００３５】
また、本実施例では、表裏において目盛を変え、一方側の目盛（裏側）を簡略目盛としている。従って、大雑把に測定する場合には裏返して測定することで瞬時におよその長さを知ることができ、非常に使い易い定規としている。
【００３６】
また、図４に示すように目印などを鉛筆などで書き込みできる透明なメンディングテープ15を貼着している。
【００３７】
尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。
【００３８】
【発明の効果】
本発明は上述のように構成したから、ネジ回し操作を行わなくても、ワンタッチで測定位置（測定時の全体長）を固定ロックでき、またその解除もワンタッチで行え、しかも確実にロックされているか否かを一見で視認でき、量産性も劣らず容易に実現可能な画期的な伸縮式箱尺となる。

[0002]
[Prior art and problems to be solved by the invention]
A conventional telescopic box measure has a slightly smaller diameter cylinder with a predetermined scale on a large diameter cylinder with a predetermined scale. For example, when measuring the internal method, the body is pulled out and slidably inserted, and each is sequentially pulled out and installed between the measuring parts, and the scale at the specified indication position is read as the internal length. It is configured so that it can be measured.
[0003]
In addition, each cylinder is configured so that the maximum pulled-out position is locked and held by the locking mechanism, and each cylinder is fixed so that the entire length can be fixed and fixed even at the middle of the pull-out position. Is provided with a tightening screw mechanism.
[0004]
Therefore, by tightening this tightening screw, the locking position pulled out to the maximum can be fixed and locked, and the cylinder in the middle of pulling can also be fixed and locked at the measurement position. It is very convenient to carry and see the excess and deficiency with this measured internal law.
[0005]
However, although this tightening screw can be easily provided, it can be visually confirmed whether it is securely fixed and held, that is, whether it is sufficiently tightened and fixed so that the cylinder cannot move. Can not.
[0006]
Therefore, it may be carried from the measurement position even if it has not yet been tightened, or the entire length that should have been locked due to insufficient tightening may be distorted by the movement of the cylinder.
[0007]
Further, when locking in a state in which the inner method is measured, it is necessary to turn the tightening screw to operate, so that it is not easy to quickly fix at a predetermined position without error. There is also a risk of damaging the cylinder with the screw.
[0008]
The present invention finds such a problem and solves this problem. The measurement position (the overall length during measurement) can be fixed and locked with a single touch without performing a screwing operation with a simple configuration. Can be done with a single touch, and it can be seen at a glance whether it is securely locked, and this fixed lock mechanism can be easily manufactured together with the maximum pull-out position locking mechanism, and mass production is not inferior. The object is to provide an innovative telescopic box measure that can be easily realized.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention (how to carry out the invention) considered to be suitable will be briefly described with reference to the drawings, showing its effects.
[0017]
When the cylinder 2 with a small diameter is pulled out for a predetermined length with respect to the cylinder 1 with a relatively large diameter, the pressure contact portion 4 has a diameter by turning the rotation operation handle 3 up and down (rotating in a predetermined direction). The small cylinder 2 is pressed into contact with each other so that the cylinder 2 cannot be slid relative to the large cylinder 1 and is fixedly locked at the drawing position.
[0018]
Therefore, for example, if the rotation operation handle 3 is swung up and down approximately 180 degrees on the outer surface of the cylindrical body 1 so that the fixed holding and the pressure release by the pressure contact portion 4 can be switched, the rotation operation can be performed. Only by looking at the rotational position of the handle 3, it can be seen at a glance whether or not the entire length is fixed and locked.
[0019]
Further, the turning operation handle 3 is mounted on a fitting portion 5 that is fitted in a small-diameter cylindrical body 2 that is housed in the large-diameter cylindrical body 1 and is inserted into the cylindrical body 1 and has a large diameter. If the cylindrical body 1 is configured to rotate up and down on the outer surface of the cylindrical body 1, the rotation operation handle 3 can be easily provided, and similarly to the left and right of the fitting portion 5 on which the rotation operation handle 3 is provided.

By providing the engaging portion 11 for holding and holding the maximum pulling position that is locked to the locking mechanism, it is possible to easily provide a locking mechanism that automatically locks at the maximum pulling position.
[0020]
【Example】
Specific embodiments of the present invention will be described with reference to the drawings.
[0021]
This embodiment is a triple-structure telescopic box measure that is configured so that three rectangular cylinders can be slidably protruded from each other in triplicate and the overall length can be extended by sequentially pulling out each cylinder. The invention is applied, and each cylinder is provided with a scale capable of reading the entire length at a predetermined designated position. It is configured so that the internal method can be measured by reading
[0022]
Of course, the present invention is not limited to this embodiment, and the number of insertions of the large-diameter cylinder and the small-diameter cylinder may be one, two as in this embodiment, or more, and a scale. Instead of reading, the entire length may be digitally displayed by a digital counter.
[0023]
In this embodiment, each of the insertion structures of the relatively large diameter cylinder 1 and the small diameter cylinder 2 is provided with a pull-out position fixing mechanism and a maximum pull-out position locking mechanism, This structure will be described in detail below.
[0024]
In the present embodiment, the turning operation handle 3 is pivotally attached to the upper portion of the fitting portion 5 that is fitted in the large-diameter cylinder 1 and can be fitted to the small-diameter cylinder 2. A fixing operation portion 6 having a distal end portion of the handle 3 as an operation portion and a base end portion as a pressure contact portion is dropped into the cylindrical body 1 from an attachment hole 7 provided in the large-diameter cylindrical body 1 and is internally installed. Then, the press contact portion 4 provided on the inner side of the fitted portion 5 as a plate-like interposition spacer that is pressed by the press contact action portion by rotating the rotating operation handle 3 of the fixing operation portion 6 is the fixing operation portion. The cylinder 2 is pressed into contact with the small-diameter cylinder 2 inserted through the cylinder 6, and the cylinder 2 is clamped and fixed at the operation position.
[0025]
That is, the fitted portion 5 of the present embodiment is formed by a U-shaped member having an upper opening, a pivot shaft 8 is installed on the upper end portion of the fitted portion 5, and the pivot operation is performed on the pivot shaft 8. The handle 3 is pivotably pivoted to form the fixing operation portion 6, and the fixing operation portion 6 is dropped through a mounting hole 7 provided in the large-diameter cylindrical body 1 and is installed. The rotating operation handle 3 is protruded from the outer surface of the cylindrical body 1 and is disposed so as to be capable of switching 180 degrees in the length direction so that it can be reversed. The small-diameter cylindrical body 2 inserted through the large-diameter cylindrical body 1 is inserted and disposed, and is disposed in the fitted portion 5 by the press-contacting action portion at the base end portion of the rotating operation handle 3. The pressed part 4 is in contact with the small-diameter cylindrical body 2 so that the cylindrical body 2 can be firmly fixed without being damaged.
[0026]
Therefore, if the rotation operation handle 3 is tilted to one side, the pressure contact is released and the cylindrical body 2 can be pulled out and slid freely, and if it is tilted to the opposite side, it is pressed and tightened. Therefore, the cylindrical body 2 is prevented from sliding and is fixedly locked.

The outer surface of the projecting portion of the member 12 is brought into contact with the measurement surface as shown in FIG. 3, for example, so that the larger diameter cylinder 1 and the smaller diameter cylinder are caused by the projecting length of the abutting end member 12. 2 can be arranged in a state separated from the abutting portions of the measurement surface. Therefore, as shown in FIG. 3, for example, even if there is a protrusion or a column between the contact portions (measurement portions), the inner method can be measured while avoiding this, and the method is very practical.
[0035]
In the present embodiment, the scale is changed on the front and back sides, and the scale on one side (back side) is a simple scale. Therefore, when measuring roughly, it is possible to know the approximate length instantly by turning it over, making it a very easy to use ruler.
[0036]
Further, as shown in FIG. 4, a transparent mending tape 15 on which a mark or the like can be written with a pencil or the like is attached.
[0037]
Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
[0038]
