Description

本考案は、主として高枝の切断に用いる高枝切り鋏の把手構造に関し、特には、組立性に優れた簡易な構造を有する把手構造及び当該把手構造を備えた高枝切り鋏に関するものである。   The present invention relates to a handle structure of a high branch cutting rod mainly used for cutting high branches, and more particularly to a handle structure having a simple structure excellent in assemblability and a high branch cutting rod provided with the handle structure.

従来、高枝切鋏の把手構造に係るものであって、特に支筒に対して回動自在な高枝切鋏の把手構造としては、把持杆５の内部に設けた筒部（支筒）を柄の後端部へ回動し得るように嵌合するととともに、該柄の一部に突設した規制ピンを、筒部において周方向へ略半周の１８０°から２７０°程度とした適宜の角度範囲に亘って形成した周溝内に臨ませることにより、柄に対して軸方向には移動せず、該周溝の形成範囲内で回動し得るよう連結した構造を有する把手構造が公知である（例えば、特許文献１参照。）。   2. Description of the Related Art Conventionally, the handle structure of a high branch cutting rod is related to a handle structure of the high branch cutting rod. An appropriate angle range in which the restricting pin protruding from a part of the handle is approximately half-circumferentially 180 ° to 270 ° in the circumferential direction in the cylindrical portion while being fitted so as to be pivotable to the rear end portion A grip structure having a structure in which it is not moved in the axial direction with respect to the handle and can be rotated within the formation range of the circumferential groove by being exposed to the circumferential groove formed over the surface is known. (For example, refer to Patent Document 1).

また、本出願人が先にした発明であって、例えば、支筒の一端部に鋏、他端部に把手と、支筒内部に設置され、鋏と把手を連結するロッドを備え、支筒の軸心に対して把手を回動自在とする高枝切鋏の把手構造において、把手に設置される被装体の周面には周溝が形成され、筒状体のベース部から径方向に弾性を有して突出する係合部を備えるスリーブを被装体に嵌入し、係合部を周溝と係合させ、支筒をスリーブに嵌入し、支筒に設置される支持部材とスリーブを係止部材にて固着することを特徴とする高枝切鋏の把手構造が公知である（例えば、特許文献２参照。）。   Further, the present invention is an invention previously made by the present applicant, and includes, for example, a rod at one end of the branch, a handle at the other end, a rod installed inside the branch, and a rod for connecting the rod and the handle. In the handle structure of a high branch cutting rod that allows the handle to rotate with respect to the shaft center, a circumferential groove is formed on the peripheral surface of the mounted body that is installed on the handle, and extends radially from the base portion of the cylindrical body.

実開昭６１−１７５９４７号公報Japanese Utility Model Publication No. 61-175947 特許第５４８３９９８号公報Japanese Patent No. 5483998

上記特許文献１に係る考案によれば、規制ピンによって周溝の形成範囲内で回動し得る構造が実現される。ここで、支筒は軽量化の観点からも薄く形成されているところ、規制ピンを取り付けるための螺子穴に螺合させるには、螺子穴が僅かにしか形成できず、前記規制ピンは容易に脱落する。このような事態を避けるためには、ネジ山を増やす為にバーリング加工を施す必要があった。   According to the device according to Patent Document 1, a structure that can be rotated within the formation range of the circumferential groove by the restriction pin is realized. Here, the support tube is thinly formed from the viewpoint of weight reduction. However, in order to be screwed into the screw hole for attaching the restriction pin, only a few screw holes can be formed, and the restriction pin can be easily formed. take off. In order to avoid such a situation, it was necessary to perform burring to increase the thread.

しかし、支筒が硬く高強度を有するアルミニウム等である場合には、当該加工は困難であった。また、長期に亘り使用していると、把手の回動時に周溝の縁部が規制ピンへ繰り返し衝突することで、規制ピンの螺子山が衝撃によって損傷し、当該規制ピンが抜脱する虞がある。
また、バーリング加工を施すことができた場合であっても、当該規制ピンの脱抜の虞は依然として解消されず、繰り返しのバーリング加工を行っても、十分な強度を保持できない欠点がある。 However, when the support tube is made of hard aluminum having high strength, the processing is difficult. In addition, when used for a long period of time, the edge of the circumferential groove repeatedly collides with the restriction pin when the handle is rotated, so that the thread of the restriction pin may be damaged by impact and the restriction pin may be pulled out. There is.
Further, even when burring can be performed, the possibility of the withdrawal of the regulation pin is still not solved, and there is a drawback that sufficient strength cannot be maintained even if repeated burring is performed.

上記特許文献２に係る発明は、把手に設置される被装体の周面には周溝が形成され、筒状体のベース部から径方向に弾性を有して突出する係合部を備えるスリーブを被装体に嵌入し、係合部を周溝と係合させ、支筒をスリーブに嵌入し、支筒に設置される支持部材とスリーブを係止部材にて固着する、又はベース部の径方向に突出して形成される突部のスリット部に支持部材を挿入し、係止部材にてスリット部の幅を変形させ、支持部材を狭持して固着することから、スリーブの内側に支筒が位置し、係合部はスリーブの内径方向に撓むことがないので、係合部は周溝と係合した状態で、スリーブを支筒に固着することができる点において優れる。また、支筒にバーリング加工等を施す必要がなく、従来における支筒の厚みを更に薄くすることができるので、支筒の軽量化を図ることができる点において優れるものである。   The invention according to Patent Document 2 includes an engaging portion that is formed with a circumferential groove on a peripheral surface of an object to be installed on a handle and protrudes in a radial direction from the base portion of the cylindrical body. Insert the sleeve into the substrate, engage the engaging part with the circumferential groove, insert the support tube into the sleeve, and fix the support member and sleeve installed on the support tube with the locking member, or the base part Since the support member is inserted into the slit portion of the projection formed to protrude in the radial direction of the sleeve, the width of the slit portion is deformed by the locking member, and the support member is held and fixed, so that the inside of the sleeve Since the support tube is positioned and the engaging portion does not bend in the inner diameter direction of the sleeve, the sleeve is excellent in that the sleeve can be fixed to the support tube while the engaging portion is engaged with the circumferential groove. Further, it is not necessary to perform a burring process or the like on the support tube, and the thickness of the conventional support tube can be further reduced, which is excellent in that the support tube can be reduced in weight.

その一方で、支筒と被装体との間に複雑な形状の専用のスリーブを備える必要があり、係止手段を更に取付ける必要があることから、組立工数が増加し、組立が複雑化する点において改善の余地があった。   On the other hand, it is necessary to provide a dedicated sleeve having a complicated shape between the support tube and the object to be mounted, and it is necessary to further attach the locking means, which increases the number of assembly steps and makes the assembly complicated. There was room for improvement.

本考案は、以上の事情に鑑みて慣れたものであり、先行文献１に係る考案に開示されるようなバーリング加工を施す必要もなく、先行文献２に係る発明における支筒と同等の厚み程度を確保して支筒の軽量化を確保した上で、且つ、更に先行文献２におけるスリーブを用いることもなく、更に組立性にも優れた高枝切り鋏の把手構造、及び当該把手構造を備えた高枝切り鋏の提供を、考案が解決しようとする課題とする。   The present invention is accustomed in view of the above circumstances, and it is not necessary to perform burring processing as disclosed in the device according to the prior art document 1, and is about the same thickness as the support tube in the invention according to the prior art document 2.

本実施例に係る高枝切り鋏Ｓの支筒１は略円筒であり、図３（ａ）に示すように、その一部の側面には長手方向へ連続する平面部を形成した構成としている。本実施例においては当該平面であって前記把手５の周溝２０に重なる位置に規制ピン３を取り付けるものとしている。   The support tube 1 of the high branch cutting rod S according to the present embodiment is substantially cylindrical, and as shown in FIG. 3 (a), a part of the side surface is formed with a flat portion continuous in the longitudinal direction. In this embodiment, the regulation pin 3 is attached to a position that is in the plane and overlaps the circumferential groove 20 of the handle 5.

本実施例に係る規制ピン３は、頭部３０及び軸部３１とからなる。頭部３０は前記周溝２０の周壁面と当接して支筒１の軸方向を基準とする回動を規制する手段となる。軸部３１は、支筒１に対する取付手段となる。ここで軸部３１は雄螺子部３２を備えており、当該支筒１に対して直接取付けるのではなく、本考案における結合部材として機能するブラインドナット４を介して取付けるものとしている。   The restriction pin 3 according to this embodiment includes a head portion 30 and a shaft portion 31. The head 30 is in contact with the peripheral wall surface of the circumferential groove 20 and serves as a means for restricting rotation based on the axial direction of the support tube 1. The shaft portion 31 serves as attachment means for the support tube 1. Here, the shaft portion 31 is provided with a male screw portion 32 and is not attached directly to the support tube 1 but is attached via the blind nut 4 functioning as a coupling member in the present invention.

本実施例に使用するブラインドナット４は一端に鍔部４４を有する筒状体であって、当該筒状体のうち前記鍔部４４の下方に連続する部分を座屈部４０とし、その下方の脚部４３の内周面に少なくとも雌螺子部４２を有する構成である。   The blind nut 4 used in the present embodiment is a cylindrical body having a flange portion 44 at one end, and a portion of the cylindrical body that continues below the flange portion 44 is a buckling portion 40, and the lower portion thereof In this configuration, at least the female screw portion 42 is provided on the inner peripheral surface of the leg portion 43.

図３に示すように、当該ブラインドナット４を、取付対象となる支筒１の構成部材の表面側から先に形成した下穴に差し込み、裏面側を座屈変形させて固定するものである。座屈変形による固定は、例えばポップナット（登録商標）ツール等の公知のブラインドナット締結工具を用いて行うことができる。   As shown in FIG. 3, the blind nut 4 is inserted into a pilot hole formed first from the surface side of the constituent member of the support tube 1 to be attached, and the back side is buckled and fixed. Fixing by buckling deformation can be performed by using a known blind nut fastening tool such as a Popnut (registered trademark) tool.

具体的には、締結工具の先端の雄螺子を有する工具軸部にブラインドナット４を螺合して保持させる。この状態で前記下穴にブラインドナット４を保持した当該締結工具を挿入する。螺合状態を保持したまま工具軸部を引き抜き方向へ移動させる。当該移動によって座屈部４０が拡径変形して当該ブラインドナット４の鍔部と座屈部４０とで支筒１の周壁を挟持する。これによって、ブラインドナット４を周壁に固定した態となる。固定後に、締結工具の先端の工具軸部を逆回転させることで、当該締結工具のみを引き抜く一連の操作で行う。   Specifically, the blind nut 4 is screwed and held on a tool shaft portion having a male screw at the tip of the fastening tool. In this state, the fastening tool holding the blind nut 4 is inserted into the prepared hole. The tool shaft is moved in the drawing direction while maintaining the screwed state. Due to the movement, the buckling portion 40 is deformed in diameter and the peripheral wall of the support tube 1 is sandwiched between the flange portion of the blind nut 4 and the buckling portion 40. As a result, the blind nut 4 is fixed to the peripheral wall. After fixing, the tool shaft portion at the tip of the fastening tool is rotated in the reverse direction, thereby performing a series of operations for extracting only the fastening tool.

支筒１にブラインドナット４を取付けた後、当該支筒１の後端を把手５の被装部２に差し込む。支筒の平面部１１によって被装部２との間に間隙１０が形成されているため、ブラインドナット４の鍔部４４が当該被装部２に接触せずに差し込まれる。
ブラインドナット４の開口が周溝２０内に露呈した状態で、規制ピン３をブラインドナット４に螺合させることで、把手５から支筒１が離脱不能となり、且つ軸方向への回動が許容される構成となる。規制ピン３は、周溝に沿って、周溝端部２０ａ、２０ａ間を回動可能となる。 After the blind nut 4 is attached to the support tube 1, the rear end of the support tube 1 is inserted into the mounted part 2 of the handle 5. Since the gap 10 is formed between the planar portion 11 of the support cylinder and the mounted portion 2, the flange portion 44 of the blind nut 4 is inserted without contacting the mounted portion 2.
With the opening of the blind nut 4 exposed in the circumferential groove 20, the restriction pin 3 is screwed into the blind nut 4 so that the support cylinder 1 cannot be detached from the handle 5 and is allowed to rotate in the axial direction. It becomes the composition to be done. The restriction pin 3 can rotate between the circumferential groove end portions 20a and 20a along the circumferential groove.

支筒１内には、最終的にロッド７がその長手方向に貫通するため、当該ロッド７の動作を阻害しない範囲で、一定の長さの脚部４３を有するブラインドナット４を用いることによって、当該ブラインドナット４内の雌螺子部４２と、規制ピン３の軸部３１に形成した雄螺子部３２とが軸方向に亘って所定範囲で螺合状態を確保するため、従来のバーリングに対する規制ピン３の取付と比較して規制ピン３近傍の耐久性を飛躍的に向上させることができる。   In the support tube 1, since the rod 7 finally penetrates in the longitudinal direction thereof, by using the blind nut 4 having the leg portion 43 of a certain length within a range not inhibiting the operation of the rod 7, Since the female screw portion 42 in the blind nut 4 and the male screw portion 32 formed on the shaft portion 31 of the restriction pin 3 ensure a screwed state within a predetermined range in the axial direction, the restriction pin for the conventional burring Compared with the attachment of 3, the durability in the vicinity of the regulation pin 3 can be drastically improved.

上記実施例に係る支筒１は平面部を備えた構成としているが、本考案は当該構成に限定されるものではなく、例えば、平面部を有しない構成とすることもできる。支筒１が平面部を有しない場合には、例えば、周面に適した湾曲形状のブラインドナット４を使用することもできる。一方で、上記実施例における平面部を備えた構成としたものを用いる場合にあっては、支筒１の後端を把手５の被装部２に差し込む際に、支筒１と被装部２との間に間隙１０が形成され、上記したように、ブラインドナット４の鍔部が被装部２と接触せず、被装部２を傷つける可能性を大幅に低減できるとともに、円滑な組立に資することができる。   Although the support tube 1 which concerns on the said Example is taken as the structure provided with the plane part, this invention is not limited to the said structure, For example, it can also be set as the structure which does not have a plane part. When the support cylinder 1 does not have a flat surface portion, for example, a curved blind nut 4 suitable for the peripheral surface can be used. On the other hand, in the case of using the configuration provided with the flat portion in the above embodiment, when inserting the rear end of the branch tube 1 into the mounted portion 2 of the handle 5, the branch tube 1 and the mounted portion. 2 and the gap 10 of the blind nut 4 does not come into contact with the mounted part 2 as described above, and the possibility of damaging the mounted part 2 can be greatly reduced and smooth assembly can be achieved. Can help.

また、本考案によれば、基本的には、ブラインドナット４における雌螺子部４２の形成範囲を限定するものではないが、少なくとも座屈部４０より下端側の脚部４３に雌螺子部４２が形成され、当該支筒１の周壁の厚さの二倍以上で、ロッド７の側面の当接位置以内までの範囲であるものとすることにより、バーリング加工では得られない範囲での雌螺子部４２及び雄螺子部３２の螺合が実現し、規制ピン３の頭部３０に対して衝撃が加わった場合においても、当該衝撃が分散して螺子の変形等が低減され、より耐久性を向上できる利点を有する。   Further, according to the present invention, the formation range of the female screw portion 42 in the blind nut 4 is basically not limited. However, at least the female screw portion 42 is provided on the leg portion 43 on the lower end side from the buckling portion 40. The female screw portion in a range that is formed and is not less than twice the thickness of the peripheral wall of the support tube 1 and within the contact position of the side surface of the rod 7, and cannot be obtained by burring. Even when an impact is applied to the head 30 of the regulation pin 3, the impact is dispersed and the deformation of the screw is reduced, so that the durability is further improved. Has the advantage of being able to.

また、上記実施例によれば、ブラインドナット４に対して直接規制ピン３を取付けた構成としているが、本考案においては、ブラインドナット４と規制ピン３との間に単数若しくは複数のワッシャー等を挟持させて取着することができる。   Further, according to the above embodiment, the restriction pin 3 is directly attached to the blind nut 4. However, in the present invention, one or more washers or the like are provided between the blind nut 4 and the restriction pin 3. Can be clamped and attached.

また、上記実施例によれば、筒状部の中心軸を中心として概ね中心角αを３００°程度の範囲で形成したものとしているが、本考案は中心角αを３００°に限定するものではなく、被装部の材質、大きさ等によって強度が確保できる範囲で自由に設定することができる。   Further, according to the above embodiment, the central angle α is generally formed in the range of about 300 ° around the central axis of the cylindrical portion, but the present invention does not limit the central angle α to 300 °. However, it can be freely set within a range in which the strength can be ensured depending on the material, size, etc. of the mounted part.
