Therefore, by moving the slide block 19 up and down, the main leg 11 and the auxiliary leg 12 can be opened and closed, or by opening and closing one of the auxiliary legs 12 relative to the main leg 11, the three legs can be opened and closed. The main leg 11 and the auxiliary leg 12 open and close as one.

前記主脚11、前記補助脚12が所定角度開いた状態、即ち前記三脚装置2が安定に自立可能な状態で、必要ならば前記クランプ機構22により前記スライドブロック19を前記主脚11に固定する。 When the main leg 11 and the auxiliary leg 12 are opened at a predetermined angle, that is, the tripod device 2 can stably stand on its own, the slide block 19 is fixed to the main leg 11 by the clamp mechanism 22, if necessary. .

尚、前記三脚装置2の最大開度は、前記ステー23の長さによって決定されるが、前記三脚装置2の過度な開きを防止する為、前記主脚11に前記スライドブロック19の下方への移動を制限する為のストッパを設けてもよい。 The maximum opening degree of the tripod device 2 is determined by the length of the stay 23, but in order to prevent the tripod device 2 from opening excessively, the main leg 11 is provided with a downward slide block 19. A stopper may be provided to limit movement.

運搬する場合、前記主脚11、補助脚12は畳まれるが、畳まれた状態を保持するパイプホルダ25が前記主脚11に設けられる。 When transporting, the main leg 11 and the auxiliary leg 12 are folded, and the main leg 11 is provided with a pipe holder 25 that maintains the folded state.

該パイプホルダ25について、図5、図6により説明する。 The pipe holder 25 will be explained with reference to FIGS. 5 and 6.

該パイプホルダ25は前記主脚11、前記補助脚12を折畳んだ状態で、前記下パイプブロック21と干渉しない様、該下パイプブロック21より下方の位置で前記主脚11に固定されている。 The pipe holder 25 is fixed to the main leg 11 at a position below the lower pipe block 21 so as not to interfere with the lower pipe block 21 with the main leg 11 and the auxiliary leg 12 folded. .

前記パイプホルダ25は前記主脚11に嵌合する基部26と、該基部26から延出する2つのアーム部27と該アーム部27の先端にそれぞれ設けられたパイプ把持部28とを有し、前記2つのアーム部27は前記2つのブラケット15と同方向に延出している。前記パイプ把持部28の先端部が所要幅欠切され、開放されており、欠切された幅は、前記補助脚12の外形よりも若干狭くなっている。 The pipe holder 25 has a base portion 26 that fits into the main leg 11, two arm portions 27 extending from the base portion 26, and pipe grip portions 28 provided at the tips of the arm portions 27, respectively. The two arm portions 27 extend in the same direction as the two brackets 15. The distal end portion of the pipe gripping portion 28 is cut to a required width and left open, and the cut width is slightly narrower than the outer shape of the auxiliary leg 12.

而して、前記補助脚12を前記パイプ把持部28に押込めば、該パイプ把持部28が弾性変形し、前記補助脚12が前記パイプ把持部28に嵌合し、又該パイプ把持部28の弾性力で前記補助脚12を保持する。 When the auxiliary leg 12 is pushed into the pipe gripping part 28, the pipe gripping part 28 is elastically deformed, the auxiliary leg 12 fits into the pipe gripping part 28, and the pipe gripping part 28 The auxiliary leg 12 is held with the elastic force of .

補助脚12,12を前記パイプ把持部28,28に嵌合した状態が、図6に示されており、該パイプホルダ25により前記主脚11、補助脚12は畳んだ状態が保持される。 A state in which the auxiliary legs 12, 12 are fitted into the pipe gripping parts 28, 28 is shown in FIG. 6, and the main leg 11 and the auxiliary leg 12 are held in the folded state by the pipe holder 25.

尚、前記基部26は前記主脚11に対して摺動可能とし、止めネジ29により適宜な位置に固定可能としてもよい。 The base 26 may be slidable relative to the main leg 11 and may be fixed at an appropriate position with a set screw 29.

尚、前記三脚装置2の運搬時に、前記主脚11、前記補助脚12内の2本を同時に保持する。或は三脚装置2をバンドで束ねる等すれば、前記パイプホルダ25は省略してもよい。 Incidentally, when the tripod device 2 is transported, two of the main legs 11 and the auxiliary legs 12 are held at the same time. Alternatively, if the tripod device 2 is bundled with a band, the pipe holder 25 may be omitted.

前記三脚装置2を開脚する場合に、一旦各脚が開方向に動作し始めると、前記三脚装置2を傾けると、脚(補助脚12)の自重により自然と開く、或は軽微な力を添えることで容易に開くことができる。 When opening the legs of the tripod device 2, once each leg begins to move in the opening direction, when the tripod device 2 is tilted, the legs (auxiliary legs 12) will open automatically due to their own weight, or a slight force will be applied. You can easily open it by attaching it.

然し乍ら、束ねた状態から開脚する場合には、各脚を開方向に移動させる為の(各脚が離反方向に変位する為の)初動を与える必要がある。特に、前記パイプホルダ25が具備され、前記補助脚12が該パイプホルダ25に保持されている場合等は、前記補助脚12が前記パイプホルダ25から脱する外力を与える必要がある。 However, when opening the legs from a bundled state, it is necessary to provide an initial motion to move each leg in the opening direction (to displace each leg in the separating direction). In particular, when the pipe holder 25 is provided and the auxiliary leg 12 is held by the pipe holder 25, it is necessary to apply an external force to cause the auxiliary leg 12 to disengage from the pipe holder 25.

最も単純には、片手で前記主脚11、前記補助脚12内の1本を保持し、他の1本を開脚する様に力を与えればよい。 The simplest method is to hold one of the main leg 11 and the auxiliary leg 12 with one hand and apply force to open the other leg.

この場合、両手を必要とする、或は持替える必要が生じる。 In this case, both hands are required or it becomes necessary to switch hands.

以下に説明する実施例では、開閉機構を備え、片手で簡単に、前記三脚装置2に開方向の初動を与えることができる。 In the embodiment described below, an opening/closing mechanism is provided, and an initial movement in the opening direction can be easily given to the tripod device 2 with one hand.

以下、図7、図8を参照して、本実施例に適用可能な第1の開閉機構について説明する。 The first opening/closing mechanism applicable to this embodiment will be described below with reference to FIGS. 7 and 8.

図7、図8に示される開閉機構31は、前記主脚11、前記補助脚12の上端部で、前記ヒンジ20の下側に設けられる。又、図7、図8に於いて、前記補助脚12,12は重なった位置にあり、図では手前の補助脚12のみが見えている。 The opening/closing mechanism 31 shown in FIGS. 7 and 8 is provided below the hinge 20 at the upper ends of the main leg 11 and the auxiliary leg 12. In addition, in FIGS. 7 and 8, the auxiliary legs 12 and 12 are in an overlapping position, and only the auxiliary leg 12 in the front is visible in the figures.

前記主脚11の上端部にバタフライ形の取手32が前記主脚11に摺動自在に設けられている。前記取手32は、前記主脚11が嵌合する軸受部32aと該軸受部32aから左右に対称に突出する取手部32bを有しており、該取手部32bは枠形状であり、片手で或は両手で持つことが可能となっている。 A butterfly-shaped handle 32 is provided at the upper end of the main leg 11 so as to be slidable thereon. The handle 32 has a bearing part 32a into which the main leg 11 fits, and a handle part 32b that projects symmetrically from the bearing part 32a to the left and right. can be held with both hands.

前記取手32は、前記主脚11と、前記補助脚12が折畳まれた状態で、前記主脚11の上部に収納され、収納された状態では一方の取手部32bが補助脚12,12間を挿通し、且つ前記上パイプブロック16と前記補助脚12に設けられたカムブロック35(後述)との間に収る様になっている。尚、前記取手部32bが前記カムブロック35に当接し、該カムブロック35が前記取手部32bの下方への動きを規制し、前記取手32が収納状態を保持される様にしてもよく、或は図示していないが、連結ブロック13と前記軸受部32a間に前記取手32の自重を支持する程度のバネを設けてもよい。 The handle 32 is stored above the main leg 11 in a state where the main leg 11 and the auxiliary leg 12 are folded, and in the stored state, one handle portion 32b is inserted between the auxiliary legs 12 , and is arranged between the upper pipe block 16 and a cam block 35 (described later) provided on the auxiliary leg 12. Note that the handle portion 32b may come into contact with the cam block 35, and the cam block 35 may restrict the downward movement of the handle portion 32b, so that the handle 32 is maintained in the stored state. Although not shown, a spring sufficient to support the weight of the handle 32 may be provided between the connecting block 13 and the bearing portion 32a.

前記取手32は、運搬時に三脚装置2を保持、支持する為に用いられ、運搬時の作業性の向上が図れる。 The handle 32 is used to hold and support the tripod device 2 during transportation, thereby improving workability during transportation.

前記軸受部32aの下端部、図中、手前と向う側にそれぞれ前記補助脚12に向って突出するコマ部33が形成される。両コマ部33,33が突出する方向は前記ブラケット15、15が突出する方向と同じ、又は略同じである(図4参照)。尚、前記コマ部33が設けられる位置は前記軸受部32aの下端部に限らず、前記取手部32bの下端部等、後述するカム片36と係合する位置であればよい。 A piece part 33 is formed at the lower end of the bearing part 32a, which projects toward the auxiliary leg 12, at the front and opposite sides in the figure, respectively. The direction in which both the pieces 33, 33 protrude is the same or substantially the same as the direction in which the brackets 15, 15 protrude (see FIG. 4). Note that the position where the piece part 33 is provided is not limited to the lower end of the bearing part 32a, but may be any position such as the lower end of the handle part 32b, where it engages with a cam piece 36, which will be described later.

前記補助脚12の所要位置、即ち、収納された前記取手32の下側に位置様に、カムブロック35が取付け固定される。該カムブロック35に前記主脚11の中心に向って突出するカム片36が突設され、該カム片36は前記コマ部33の下方に位置し、該コマ部33と係合可能な位置となっている。 A cam block 35 is attached and fixed at a desired position on the auxiliary leg 12, that is, below the housed handle 32. A cam piece 36 protruding toward the center of the main leg 11 is provided on the cam block 35, and the cam piece 36 is located below the piece 33 and at a position where it can engage with the piece 33. It has become.

又前記カム片36の形状は、上面が下方に傾斜する形状となっており、前記コマ部33が前記カム片36に当接し、該カム片36が前記コマ部33から下方への力を受けた場合、前記カム片36に外側(前記カムブロック35が前記主脚11から離反する方向)への分力、好ましくは前記補助脚12開脚方向の分力が作用する様になっている。 The shape of the cam piece 36 is such that the upper surface is inclined downward, and the piece 33 contacts the cam piece 36, and the cam piece 36 receives a downward force from the piece 33. In this case, a component force is applied to the cam piece 36 outwardly (in the direction in which the cam block 35 moves away from the main leg 11), preferably in the direction in which the auxiliary leg 12 is opened.

次に、前記開閉機構31の開動作を説明する。 Next, the opening operation of the opening/closing mechanism 31 will be explained.

前記主脚11、前記補助脚12が畳まれた状態(図7参照)から、前記取手32を下方に押下げると、前記コマ部33が前記カム片36に当接し、更に押下げると前記コマ部33とが前記カム片36間の相互作用で、前記カムブロック35(前記補助脚12)が前記主脚11から離反する。 When the handle 32 is pushed down from the state in which the main leg 11 and the auxiliary leg 12 are folded (see FIG. 7), the top portion 33 comes into contact with the cam piece 36, and when pushed down further, the top The cam block 35 (the auxiliary leg 12) separates from the main leg 11 due to the interaction between the cam piece 36 and the cam piece 36.

即ち、前記取手32を押下げることで、前記補助脚12に開脚方向への初動が与えられる。又、前記補助脚12が前記パイプホルダ25に保持されている場合は、前記取手32の押下げで、前記補助脚12が前記パイプホルダ25から離脱する。 That is, by pushing down the handle 32, the auxiliary leg 12 is given an initial movement in the leg opening direction. Further, when the auxiliary leg 12 is held by the pipe holder 25, the auxiliary leg 12 is detached from the pipe holder 25 by pushing down the handle 32.

尚、前記開閉機構31の開動作を効果的にする為、図7、図8の様に前記主脚11を前記補助脚12側に傾けた状態とすると、前記補助脚12に重力による開脚方向の力が作用するので、初動(前記開閉機構31による開脚動作)が容易になる。又、初動後は重力により前記補助脚12が自重で開脚動作する。更に、前記取手32を下げることで、前記スライドブロック19を下方に移動させることができ、前記補助脚12に開脚動作させることができる。 In order to make the opening operation of the opening/closing mechanism 31 more effective, if the main leg 11 is tilted toward the auxiliary leg 12 as shown in FIGS. 7 and 8, the auxiliary leg 12 is opened by gravity. Since a directional force is applied, the initial movement (opening/closing mechanism 31) becomes easy. Further, after the initial movement, the auxiliary legs 12 open their legs due to their own weight due to gravity. Further, by lowering the handle 32, the slide block 19 can be moved downward, and the auxiliary legs 12 can be operated to open the legs.

従って、前記取手32の下方への移動のみで、前記三脚装置2の開脚を行える。 Therefore, the tripod device 2 can be opened by only moving the handle 32 downward.

尚、前記取手32の形状は、上記説明のバタフライ形に限らず、種々の形状とすることかできる。例えば、前記コマ部33が設けられない一方の前記取手部32bを省略したもの、或は、図12で示されるハンドル41(後述)の様なものであってもよい。要は、前記主脚11に対して摺動自在で、前記コマ部33が設けられていればよい。 Note that the shape of the handle 32 is not limited to the butterfly shape described above, but can be made into various shapes. For example, one of the handle parts 32b in which the top part 33 is not provided may be omitted, or a handle 41 (described later) shown in FIG. 12 may be used. In short, it is sufficient that the top portion 33 is slidable relative to the main leg 11.

以下、図9~図11を参照して、本実施例に適用可能な第2の開閉機構について説明する。尚、図9~図11中、図7、図8中で示したものと同一のものには同符号を付しその説明を省略する。 The second opening/closing mechanism applicable to this embodiment will be described below with reference to FIGS. 9 to 11. In FIGS. 9 to 11, the same components as those shown in FIGS. 7 and 8 are designated by the same reference numerals, and their explanations will be omitted.

取手32は主脚11に対して回転自在且つ摺動自在に嵌合されており、前記主脚11には前記取手32の上方への移動を制限するストッパ37が設けられている。 The handle 32 is rotatably and slidably fitted to the main leg 11, and the main leg 11 is provided with a stopper 37 for restricting upward movement of the handle 32.

前記軸受部32aの下側に前記主脚11に外嵌されたバネ受け38が設けられる。該バネ受け38は前記軸受部32a(即ち取手32)とは、切離されており、前記バネ受け38は前記軸受部32aに当接し、前記取手32に対して回転可能であり、又前記主脚11に対して摺動自在となっている。 A spring receiver 38 externally fitted onto the main leg 11 is provided below the bearing portion 32a. The spring receiver 38 is separated from the bearing portion 32a (i.e., the handle 32), and the spring receiver 38 is in contact with the bearing portion 32a and is rotatable with respect to the handle 32. It is slidable on the leg 11.

前記バネ受け38の下側にスライドブロック19が設けられており、該スライドブロック19と前記バネ受け38間にスプリング39が複数設けられている。該スプリング39は所定ピッチで全周に亘って複数設けられている。尚、該スライドブロック19と前記バネ受け38間に前記主脚11外嵌する圧縮コイルスプリングが設けられてもよい。前記取手部32bの下枠の一側面で且つ前記補助脚12に対峙する部位にロック部材40が設けられる。該ロック部材40の材質は、弾力性を有する合成樹脂が好ましい。 A slide block 19 is provided below the spring receiver 38, and a plurality of springs 39 are provided between the slide block 19 and the spring receiver 38. A plurality of springs 39 are provided at a predetermined pitch over the entire circumference. Note that a compression coil spring that fits outside the main leg 11 may be provided between the slide block 19 and the spring receiver 38. A locking member 40 is provided on one side of the lower frame of the handle portion 32b and at a portion facing the auxiliary leg 12. The material of the locking member 40 is preferably a synthetic resin having elasticity.

該ロック部材40は、三脚装置2が畳まれた状態で、一方の補助脚12に嵌合し、該補助脚12の開脚方向(図11中、A方向)の変位を拘束するものである。 The lock member 40 fits into one of the auxiliary legs 12 when the tripod device 2 is folded, and restricts the displacement of the auxiliary leg 12 in the leg opening direction (direction A in FIG. 11). .

図11に示される様に、該ロック部材40は、前記補助脚12と嵌合する凹部40aを有し、該凹部40aを形成する舌片40bは前記補助脚12の開脚方向の変位に対して直交、又は略直交する方向に延出する。 As shown in FIG. 11, the locking member 40 has a recess 40a that fits into the auxiliary leg 12, and the tongue piece 40b forming the recess 40a resists the displacement of the auxiliary leg 12 in the leg opening direction. and extend in directions perpendicular or substantially perpendicular to each other.

図9は、三脚装置2が畳まれた状態を示しているが、畳まれた状態では前記ロック部材40が前記補助脚12に嵌合し、該補助脚12をロックした状態となっている(図11参照)。 FIG. 9 shows the tripod device 2 in a folded state. In the folded state, the locking member 40 fits into the auxiliary leg 12, and the auxiliary leg 12 is locked ( (See Figure 11).

又、三脚装置2が畳まれた状態では前記ステー23が前記主脚11と平行又は略平行であり、前記ステー23の上端は最上位に位置する。又、該ステー23の上端に連結されたスライドブロック19も又最上位に位置する。 Further, when the tripod device 2 is folded, the stay 23 is parallel or substantially parallel to the main leg 11, and the upper end of the stay 23 is located at the uppermost position. Further, the slide block 19 connected to the upper end of the stay 23 is also located at the uppermost position.

該スライドブロック19が最上位の位置で該スライドブロック19と前記バネ受け38との間隔は最小となり、この間隔の大きさは前記ストッパ37の位置で決定される。即ち、前記取手32が前記ストッパ37によって最上位の位置が決定され、更に前記バネ受け38が前記取手32(軸受部32a)に当接することで最上位の位置が決定される。 When the slide block 19 is in the uppermost position, the distance between the slide block 19 and the spring receiver 38 is the minimum, and the size of this distance is determined by the position of the stopper 37. That is, the uppermost position of the handle 32 is determined by the stopper 37, and the uppermost position is determined by the spring receiver 38 coming into contact with the handle 32 (bearing portion 32a).

前記スライドブロック19と前記バネ受け38間の最小間隔では、前記スプリング39が圧縮され、圧縮による反発力が生じた状態となっている。この反発力は前記三脚装置2が開く為の初動を与えるに十分な力となっている。 At the minimum distance between the slide block 19 and the spring receiver 38, the spring 39 is compressed and a repulsive force is generated due to the compression. This repulsive force is sufficient to provide the initial movement for the tripod device 2 to open.

尚、前記ロック部材40が前記補助脚12をロックしていることで、前記補助脚12の変位が拘束され、即ち前記スライドブロック19の変位が拘束され、前記スプリング39か圧縮された状態が維持される。即ち、前記三脚装置2が畳まれた状態が維持される。 In addition, since the locking member 40 locks the auxiliary leg 12, the displacement of the auxiliary leg 12 is restrained, that is, the displacement of the slide block 19 is restrained, and the spring 39 is maintained in a compressed state. be done. That is, the tripod device 2 is maintained in the folded state.

該三脚装置2を設置する場合、即ち、該三脚装置2を開脚させる場合、前記取手部32bを前記主脚11の軸心を中心に回転させ、前記ロック部材40を前記補助脚12から離脱させる。図11では、前記取手部32bを図中、B方向(反時計方向)に回転させることで、前記ロック部材40も前記取手部32bと一体に回転し、前記補助脚12から離脱する。 When installing the tripod device 2, that is, when opening the tripod device 2, the handle portion 32b is rotated around the axis of the main leg 11, and the locking member 40 is removed from the auxiliary leg 12. let In FIG. 11, by rotating the handle portion 32b in the direction B (counterclockwise) in the figure, the locking member 40 also rotates together with the handle portion 32b and is separated from the auxiliary leg 12.

前記補助脚12のA方向(開方向)への拘束が開放されるので、前記スプリング39の反発力による開動作の初動が行われる。 Since the restraint of the auxiliary leg 12 in the A direction (opening direction) is released, the initial movement of the opening operation is performed by the repulsive force of the spring 39.

初動が実行された後は、前記取手32を下方に引下げることで、前記バネ受け38を介して前記スライドブロック19が下方に移動され、前記ステー23が突っ張ることで、前記補助脚12の開動作が実行される。 After the initial movement is performed, by pulling down the handle 32, the slide block 19 is moved downward via the spring receiver 38, and the stay 23 is stretched, so that the auxiliary leg 12 is opened. Action is performed.

而して、第2の開閉機構では、前記三脚装置2が畳まれた状態から、前記取手32を水平方向に所定角度回転し、その後前記取手32を下方に押下げることで三脚装置2の開動作を行うことができる。 In the second opening/closing mechanism, the tripod device 2 is opened by rotating the handle 32 horizontally by a predetermined angle from the folded state of the tripod device 2, and then pushing down the handle 32. can perform actions.

次に、図12~図14を参照して、本実施例の第1応用例について説明する。尚、図12~図14中、図2、図3中で示したものと同等のものには同符号を付し、その説明を省略する。 Next, a first application example of this embodiment will be described with reference to FIGS. 12 to 14. Note that in FIGS. 12 to 14, the same components as those shown in FIGS. 2 and 3 are denoted by the same reference numerals, and their explanations will be omitted.

尚、図12は三脚装置2が畳まれた状態、図13、図14は前記三脚装置2が開脚された状態を示している。 Note that FIG. 12 shows the tripod device 2 in a folded state, and FIGS. 13 and 14 show the tripod device 2 in an opened state.

該応用例では、三脚装置2の運搬、該三脚装置2設置時の作業性を向上させる為のハンドル41が設けられている。 In this application example, a handle 41 is provided to improve workability when transporting the tripod device 2 and installing the tripod device 2.

該ハンドル41は、取扱いが容易な様に、作業者の胸の高さ当りに設けられる。 The handle 41 is provided at about the height of the operator's chest for easy handling.

該ハンドル41は分体41a,41bから成る2分割構造であり、各分体41a,41bはそれぞれ補助脚12,12に個別に取付けられる。 The handle 41 has a two-part structure consisting of segments 41a and 41b, and each segment 41a and 41b is individually attached to the auxiliary legs 12 and 12, respectively.

前記分体41a,41bは、左右対称形であるので、一方の分体41aについて説明する。 Since the divided bodies 41a and 41b are bilaterally symmetrical, one of the divided bodies 41a will be explained.

半円柱状の握り部42aの上端にバー43aが固着され、該バー43aが前記補助脚12に固定される。尚、前記バー43aが筒体(図示せず)に固定され、該筒体が前記補助脚12嵌合される、該筒体を介して前記握り部42aが前記補助脚12に取付けられる様にしてもよい。前記握り部42aは前記補助脚12と平行或は略平行となっている。 A bar 43a is fixed to the upper end of the semi-cylindrical grip portion 42a, and the bar 43a is fixed to the auxiliary leg 12. The bar 43a is fixed to a cylindrical body (not shown), and the auxiliary leg 12 is fitted into the cylindrical body, so that the grip portion 42a is attached to the auxiliary leg 12 via the cylindrical body. It's okay. The grip portion 42a is parallel or substantially parallel to the auxiliary leg 12.

前記補助脚12,12が閉じられた時は、左右の前記握り部42a,42bが合体し、1つの円柱状の握り42が構成される。該握り42は、片手で握れる程度の直径とするのが好ましい。尚、前記握り42の形状は、円柱状に限らず、楕円等握りやすい形状、大きさであればよい。又、握り部42a,42bが合体した際の接合線には適宜、窪み、溝等を形成し、容易に前記握り部42aと42bとを分離し易い様にしてもよい。 When the auxiliary legs 12, 12 are closed, the left and right grip portions 42a, 42b are combined to form one cylindrical grip 42. Preferably, the grip 42 has a diameter that allows it to be gripped with one hand. The shape of the grip 42 is not limited to a cylindrical shape, but may be any shape or size that is easy to grip, such as an ellipse. Furthermore, a recess, a groove, etc. may be appropriately formed at the joining line when the grip portions 42a and 42b are combined, so that the grip portions 42a and 42b can be easily separated.

而して、前記三脚装置2が閉じられた状態(図12参照)では、前記握り42を握って容易に運搬が可能であり、又、前記三脚装置2の設置位置で三脚装置2を開くときは、前記握り部42a,42bを両手で個々に握り直し、前記補助脚12,12を開くことで、前記主脚11も連動して開脚し、前記三脚装置2の設置が容易となる。 Therefore, when the tripod device 2 is in the closed state (see FIG. 12), it can be easily carried by grasping the grip 42, and when the tripod device 2 is opened at the installation position. By gripping the grips 42a and 42b individually with both hands and opening the auxiliary legs 12 and 12, the main legs 11 are also opened in conjunction with each other, making it easy to install the tripod device 2.

又、前記主脚11に収納ボックス45を設けてもよい。該収納ボックス45には、測定に必要なもの、或は測量装置3に付随するものを収納可能とする。例えば、測量装置3に付随する電源等を収納可能とすると、設置位置を変更する場合に、三脚装置2と電源とを個別に運搬する必要がなくなり、利便性が向上する。 Further, a storage box 45 may be provided on the main landing gear 11.
