Description

本考案は、外周面が断面円形である固定対象物を固定するホルダ装置に関するものである。   The present invention relates to a holder device for fixing a fixed object whose outer peripheral surface is circular in cross section.

従来より、例えばハンドル等のパイプ状の部材を一対のホルダを用いて固定する態様として、各ホルダに、ハンドルの外周面に嵌合し得る内周面をそれぞれ設け、これら内周面の間にハンドルを挟み込んだ状態でホルダ同士をボルト等の締付部材によって締め付ける態様が知られている(例えば特許文献1参照)。
実公平1−32511号公報
Conventionally, as an aspect of fixing a pipe-like member such as a handle using a pair of holders, each holder is provided with an inner peripheral surface that can be fitted to the outer peripheral surface of the handle, and between these inner peripheral surfaces. There is known a mode in which the holders are fastened with a fastening member such as a bolt while the handle is sandwiched (see, for example, Patent Document 1).
No. 1-332511

しかしながら、従来のものは、各ホルダの内周面全体をハンドルの外周面に当接させるように設定しているものの、ハンドルに公差があるため、各ホルダの内周面全体をハンドルの外周面に正確に当接させることは極めて困難であり、実際のところは、各ホルダの内周面の一部が、ハンドルの軸方向に平行な線に沿って当接するいわゆる線当りとなって、ハンドルがぐらつかないように、ホルダ同士を複数のネジ等の締付部材によって強く締め付け、ハンドル又はホルダを若干変形させることによって各ホルダの内周面の大部分をハンドルの外周面に当接させる態様が実施されている。しかしながらこのような態様を採用した場合、強い締付力が要求され、締付作業に手間が掛かる上、締付部材が複数必要であるため、部品点数も増えるといった不具合もあった。しかも、各締付部材の締付力がアンバランスであればハンドルを強固に固定することができないという不具合も生じる。   However, although the conventional one is set so that the entire inner peripheral surface of each holder is in contact with the outer peripheral surface of the handle, since there is a tolerance in the handle, the entire inner peripheral surface of each holder is In actuality, it is extremely difficult to make contact with each other. Actually, a part of the inner peripheral surface of each holder comes into contact with a line along a line parallel to the axial direction of the handle. In order to prevent wobbling, the holders are strongly tightened with a plurality of tightening members such as screws, and the handle or the holder is slightly deformed so that most of the inner peripheral surface of each holder is brought into contact with the outer peripheral surface of the handle. It has been implemented. However, when such an aspect is adopted, there is a problem that a strong tightening force is required, and it takes time and labor for the tightening work, and a plurality of tightening members are required, and the number of parts increases. Moreover, if the tightening force of each tightening member is unbalanced, there is a problem that the handle cannot be firmly fixed.

本考案は、このような課題に着目してなされたものであって、主たる目的は、ハンドル等の固定対象物に対する各ホルダの内周面の当接面積を有効に稼ぎ、良好な締付状態を実現できるホルダ装置を提供することにある。   The present invention has been made paying attention to such problems, and its main purpose is to effectively earn the contact area of the inner peripheral surface of each holder with respect to a fixed object such as a handle, and to achieve a good tightening state. It is providing the holder apparatus which can implement | achieve.

すなわち、本考案のホルダ装置は、外周面が断面円形である固定対象物を挟持し得る一対のホルダと、これらホルダ同士を締め付ける締付部材とを備えたものであって、前記各ホルダの内周面に、曲率の中心を他の部位の曲率の中心とずらし且つ他の部位よりも優先して前記固定対象物に当接する当接円弧面を設けたことを特徴とする。   That is, the holder device of the present invention includes a pair of holders that can hold a fixed object whose outer peripheral surface is circular in cross section, and a tightening member that tightens the holders, The circumferential surface is provided with a contact arc surface that shifts the center of curvature from the center of curvature of another part and contacts the fixed object in preference to the other part.

このようなものであれば、各ホルダの当接円弧面を固定対象物の外周面にその周方向に沿って確実に当接させて接触面積を有効に稼ぐことができるため、弱い締付力でも固定対象物を強固に挟持することが可能となり、固定対象物のぐらつきを防止することができる。加えて、このように、軸心が異なった内周面を有するホルダで締め付けることにより、固定対象物の公差を吸収することができる。   In such a case, since the contact arc surface of each holder can be reliably contacted with the outer peripheral surface of the fixed object along the circumferential direction, the contact area can be effectively obtained, so that a weak tightening force However, the fixed object can be firmly held, and the fixed object can be prevented from wobbling. In addition, the tolerance of the fixed object can be absorbed by tightening with the holder having the inner peripheral surfaces with different axis centers.

特に、一方のホルダの内周面における当接円弧面の形成部位と、他方のホルダの内周面における当接円弧面の形成部位とを異ならせていれば、各当接円弧面を確実に固定対象物に当接させることができ、より強固な締付状態を実現することができる。   In particular, if the abutting arc surface forming part on the inner peripheral surface of one holder is different from the forming part of the abutting arc surface on the inner peripheral surface of the other holder, each abutting arc surface is surely secured. It can be brought into contact with the fixed object, and a stronger tightening state can be realized.

締付作業及び締付解除作業を簡単且つ的確に行えるようにするには、各ホルダの一端部同士を回動可能に係合する係合手段を備え、各ホルダの他端部同士を単一の前記締付部材によって締め付けるようにすればよい。   In order to be able to perform the tightening operation and the tightening release operation easily and accurately, it is provided with engaging means for rotatably engaging the one end portions of the holders, and the other end portions of the holders are united with each other. The tightening member may be used for tightening.

好適な実施態様としては、前記各ホルダがアルミダイキャスト製品である態様が挙げられる。   As a preferred embodiment, an embodiment in which each of the holders is an aluminum die cast product can be mentioned.

以上説明したように本考案によれば、固定対象物に対する各ホルダの内周面の当接面積を有効に稼ぎ、良好な締付状態を実現できる。   As described above, according to the present invention, the contact area of the inner peripheral surface of each holder with respect to the fixed object can be effectively obtained, and a good tightening state can be realized.

次に、このようなホルダ装置Hを利用してハンドル4を固定する方法及び作用について図5(同図は、ホルダ装置Hでハンドル4を固定した状態を、図2(b)に対応させて示す図である)を参照して説明する。   Next, a method and an operation for fixing the handle 4 using such a holder device H will be described with reference to FIG. 5 (in the figure, the state in which the handle 4 is fixed by the holder device H corresponds to FIG. 2B). Will be described with reference to FIG.

先ず、第2ホルダH2の係合部H22を第1ホルダH1の被係合部H12に係合した状態で、第1ホルダH1の第1嵌合部H15と取付部材Tの第2嵌合部とを相互に嵌合させることにより取付部材Tに第1ホルダH1及び第2ホルダH2を仮セットする。そして、第1ホルダH1の被係合部H12を回転軸として第2ホルダH2を第1ホルダH1から離間する方向に回動するとともに、開放された第1ホルダH1の第1内周面H11にハンドル本体41を載置し、次いで第2ホルダH2を第1ホルダH1に近接する方向に回動する。これにより、ハンドル本体41の外周が各ホルダH1、H2の内周面H11、H21に被覆された状態となる。この状態において、第2ホルダH2の第2挿入孔H23、第1ホルダH1の第1挿入孔H13、取付部材Tのネジ孔がこの順で連通しており、締付部材H3の軸部H31を第2挿入孔H23から挿入するとともに、締付部材H3の操作部H32を所定方向に回転する操作力を付与することにより軸部H31の先端部をネジ孔に螺合させる。その結果、軸部H31に設けた押圧部H31aが第2ホルダH2を押圧し、第1当接円弧面H11a及び第2当接円弧面H21aの全域がハンドル本体41の外周面にその周方向に沿って当接する(図5参照)。具体的には、ホルダH1、H2の内周面H11、H21に被覆されたハンドル本体41のうち、中央部位に第1当接円弧面H11aが当接し、両端部位に各第2当接円弧面H21aが当接する。そして、これら第1当接円弧面H11a及び第2当接円弧面H21aをそれぞれハンドル本体41の外周面に接触させた状態でハンドル本体41を締め付けることによりハンドル本体41が強固に固定される。   First, in a state where the engaging portion H22 of the second holder H2 is engaged with the engaged portion H12 of the first holder H1, the first fitting portion H15 of the first holder H1 and the second fitting portion of the mounting member T. And the first holder H1 and the second holder H2 are temporarily set on the mounting member T. And while rotating the 2nd holder H2 in the direction away from the 1st holder H1 by making the to-be-engaged part H12 of the 1st holder H1 into a rotating shaft, on the 1st internal peripheral surface H11 of the open | released 1st holder H1 The handle body 41 is placed, and then the second holder H2 is rotated in the direction approaching the first holder H1. Thereby, the outer periphery of the handle body 41 is covered with the inner peripheral surfaces H11 and H21 of the holders H1 and H2. In this state, the second insertion hole H23 of the second holder H2, the first insertion hole H13 of the first holder H1, and the screw hole of the mounting member T are communicated in this order, and the shaft portion H31 of the tightening member H3 is connected. While inserting from the 2nd insertion hole H23, the front-end | tip part of the axial part H31 is screwed by the screw hole by giving the operation force which rotates the operation part H32 of the fastening member H3 in a predetermined direction. As a result, the pressing portion H31a provided on the shaft portion H31 presses the second holder H2, and the entire area of the first contact arc surface H11a and the second contact arc surface H21a is in the circumferential direction on the outer peripheral surface of the handle body 41. It abuts along (see FIG. 5). Specifically, among the handle main bodies 41 covered with the inner peripheral surfaces H11 and H21 of the holders H1 and H2, the first contact arc surface H11a contacts the central portion, and each second contact arc surface on both end portions. H21a contacts. The handle body 41 is firmly fixed by tightening the handle body 41 in a state where the first contact arc surface H11a and the second contact arc surface H21a are in contact with the outer peripheral surface of the handle body 41, respectively.

なお、第1ホルダH1の第1内周面H11にハンドル本体41を嵌合した後、ハンドル本体41の上方から第2ホルダH2を第1ホルダH1に取り付けるようにしてもよく、また、ホルダH1、H2の内周面H11、H21にハンドル本体41を挟み込んだ状態で取付部材Tに第1ホルダH1及び第2ホルダH2を仮セットするようにしてもよい。   Note that after the handle main body 41 is fitted to the first inner peripheral surface H11 of the first holder H1, the second holder H2 may be attached to the first holder H1 from above the handle main body 41, or the holder H1. The first holder H1 and the second holder H2 may be temporarily set on the mounting member T in a state where the handle body 41 is sandwiched between the inner peripheral surfaces H11 and H21 of H2.

本実施形態では、単一の締付部材H3を用いて、第1ホルダH1と第2ホルダH2とでハンドル本体41を挟持した状態で締め付けるとともに、これらホルダH1、H2を取付部材Tに取付可能にしている。そして、締付部材H3の操作部H32を前記回転方向とは逆方向に回転させる操作力を付与すると、第1当接円弧面H11a及び第2当接円弧面H21aによるハンドル本体41の締付状態が解除されるとともに、取付部材Tに対するホルダH1、ホルダH2の取付状態も解除される。その結果、ホルダ装置Hに対するハンドル4の取付姿勢、及び操作杆2に対するホルダ装置Hの取付姿勢を変更することができ、刈払作業を終えて所定の収納スペースに収納する場合には刈払機Xの全巾をコンパクトにすることが可能である。   In the present embodiment, a single fastening member H3 is used to fasten the handle body 41 between the first holder H1 and the second holder H2, and the holders H1 and H2 can be attached to the attachment member T. I have to. When the operating force for rotating the operation portion H32 of the tightening member H3 in the direction opposite to the rotation direction is applied, the handle body 41 is tightened by the first contact arc surface H11a and the second contact arc surface H21a. Is released, and the attachment state of the holder H1 and the holder H2 to the attachment member T is also released. As a result, the mounting posture of the handle 4 with respect to the holder device H and the mounting posture of the holder device H with respect to the operating rod 2 can be changed. When the brushing operation is completed and stored in a predetermined storage space, the brush cutter X It is possible to make the entire width of the compact.

このように、本実施形態に係るホルダ装置Hは、各ホルダH1、H2の内周面H11、H21に、軸心を他の部位の軸心とずらし且つ他の部位よりも優先してハンドル本体41に当接する当接円弧面H11a、H21aを設けているため、これら各当接円弧面H11a、H21aをハンドル本体41の外周面にその周方向に沿って面的に当接させることができ、当接(接触)面積を有効に稼ぎ、弱い締付力でも確実に各ホルダH1、H2の内周面H11、H21間にハンドル本体41を固定することができる。加えて、当接円弧面H11a、H21aを設けることにより各内周面H11、H21に段差が形成され、この段差により、ハンドル本体41に生じる公差を吸収でき、良好な当接状態を維持したまま締め付けることができ、ハンドル本体41のぐらつきを防止する。   As described above, the holder device H according to the present embodiment shifts the axis from the axis of the other part to the inner peripheral surfaces H11 and H21 of the holders H1 and H2, and gives priority to the handle body over the other part. Since the contact arcuate surfaces H11a and H21a that come into contact with 41 are provided, each of these contact arcuate surfaces H11a and H21a can be brought into surface contact with the outer peripheral surface of the handle body 41 along the circumferential direction thereof. The handle main body 41 can be fixed between the inner peripheral surfaces H11 and H21 of the holders H1 and H2 with certainty even with a weak tightening force. In addition, by providing contact arcuate surfaces H11a and H21a, a step is formed on each of the inner peripheral surfaces H11 and H21. By this step, tolerances generated in the handle body 41 can be absorbed, and a good contact state is maintained. The handle body 41 can be prevented from wobbling.

特に、第1ホルダH1と第2ホルダH2とを組み付けた状態において、第1ホルダH1に設けた第1当接円弧面H11aと第2ホルダH2に設けた第2当接円弧面H21aとが相互に対向しないように設定しているため、各当接円弧面H11a、H21aを確実にハンドル本体41に当接させることができ、より強固な固定状態を実現することができる。   In particular, in a state where the first holder H1 and the second holder H2 are assembled, the first contact arc surface H11a provided on the first holder H1 and the second contact arc surface H21a provided on the second holder H2 are mutually connected. Therefore, the contact arcuate surfaces H11a and H21a can be reliably brought into contact with the handle main body 41, and a more firmly fixed state can be realized.

加えて、各ホルダH1、H2の一端部同士を回動可能に係合する係合手段HKを備え、各ホルダH1、H2の他端部同士を単一の締付部材H3によって締め付けるため、締付作業及び締付解除作業を簡単に行うことができ、部品点数の削減にも資する。また、複数の締付部材H3を用いた場合に生じる不具合、すなわち、各締付部材H3の締付力がアンバランスとなり、良好な締付状態を得られないという不具合を防止することができる。殊に、本実施形態に示す刈払機のように、使用時におけるホルダ装置Hに対するハンドル4の取付姿勢(取付角度)、及び使用時又は不使用時における操作杆2に対するハンドル4の取付姿勢をその都度変更することが要求される機具に本考案のホルダ装置Hを適用することにより、ハンドルの取付姿勢(取付角度)を変更する作業を容易且つ的確に行うことができる。   In addition, an engagement means HK for rotatably engaging one end of each holder H1, H2 is provided, and the other end of each holder H1, H2 is tightened by a single tightening member H3. Attaching work and tightening releasing work can be easily performed, which contributes to a reduction in the number of parts. Further, it is possible to prevent a problem that occurs when a plurality of tightening members H3 are used, that is, a problem that the tightening force of each tightening member H3 becomes unbalanced and a good tightening state cannot be obtained. In particular, as in the brush cutter shown in the present embodiment, the mounting posture (mounting angle) of the handle 4 with respect to the holder device H during use, and the mounting posture of the handle 4 with respect to the operating rod 2 when used or not used are shown. By applying the holder device H of the present invention to a device that is required to be changed each time, it is possible to easily and accurately perform an operation of changing the mounting posture (mounting angle) of the handle.
