本発明は、例えば天井部等に設けられた吊りボルトに梁部材を連結するための連結装置に関する。 The present invention relates to a connecting device for connecting a beam member to a suspension bolt provided on, for example, a ceiling.

従来、この種の連結装置としては、例えば図１０，図１１に示すように、鉄筋コンクリート等からなる天井部から垂設された鉛直方向の吊りボルト１０１に、水平方向の梁部材１０２を連結するためのものがある。 Conventionally, as this type of connecting device, for example, as shown in FIGS. 10 and 11, in order to connect a horizontal beam member 102 to a vertical suspension bolt 101 suspended from a ceiling portion made of reinforced concrete or the like. There are things.

連結装置１０３は、一側縁においてヒンジ部１０４により開閉自在に結合される一方及び他方の支持ブロック１０５，１０６と、一方及び他方の支持ブロック１０５，１０６をその閉鎖位置において結合する複数の皿ねじ１０７とを具備している。一方及び他方の支持ブロック１０５，１０６の各閉鎖対向面には、上下方向に貫通する支持孔１０８の一方及び他方の半部１０９，１１０が形成されている。 The connecting device 103 includes one and other support blocks 105 and 106 which are connected to each other at an edge by a hinge 104 so as to be openable and closable, and a plurality of countersunk screws which connect the one and other support blocks 105 and 106 in their closed positions. 107. One and the other half portions 109 and 110 of the support hole 108 penetrating in the up-down direction are formed on the closed facing surfaces of the one and the other support blocks 105 and 106.

支持孔１０８の内壁面には、吊りボルト１０１の雄ねじ部１１１に螺合される雌ねじ部（図示省略）が形成されている。また、他方の支持ブロック１０６には、水平方向に貫通する環状の支持部１１３が形成されている。尚、梁部材１０２には支持ロッドを介して案内表示パネル等の表示部材が吊り下げられている。 On the inner wall surface of the support hole 108, a female screw portion (not shown) that is screwed into the male screw portion 111 of the suspension bolt 101 is formed. The other support block 106 is formed with an annular support portion 113 that penetrates in the horizontal direction. A display member such as a guide display panel is suspended from the beam member 102 via a support rod.

これによると、梁部材１０２を他方の支持ブロック１０６の支持部１１３に挿通し、図１０，図１１の仮想線に示すように、一方及び他方の支持ブロック１０５，１０６を閉鎖して複数の皿ねじ１０７で結合することにより、吊りボルト１０１が連結装置１０３の支持孔１０８に挿通され、支持孔１０８の雌ねじ部が吊りボルト１０１の雄ねじ部１１１に螺合する。これにより、連結装置１０３が吊りボルト１０１に取付固定され、梁部材１０２が連結装置１０３を介して吊りボルト１０１に連結される。 According to this, the beam member 102 is inserted into the support portion 113 of the other support block 106, and as shown by phantom lines in FIGS. By connecting with the screw 107, the suspension bolt 101 is inserted into the support hole 108 of the coupling device 103, and the female screw portion of the support hole 108 is screwed into the male screw portion 111 of the suspension bolt 101. Thereby, the connecting device 103 is attached and fixed to the suspension bolt 101, and the beam member 102 is connected to the suspension bolt 101 via the connecting device 103.

また、連結装置１０３の固定位置を上下方向へ変更する場合、複数の皿ねじ１０７を連結装置１０３から取り外し、図１１の実線で示すように、一方及び他方の支持ブロック１０５，１０６を開き、支持孔１０８の雌ねじ部を吊りボルト１０１の雄ねじ部１１１から離脱させ、この状態で、連結装置１０３を吊りボルト１０１に対して所望の位置まで上下移動させる。 When the fixing position of the coupling device 103 is changed in the vertical direction, the plurality of flat head screws 107 are removed from the coupling device 103, and one and the other support blocks 105 and 106 are opened and supported as shown by the solid lines in FIG. The female screw portion of the hole 108 is detached from the male screw portion 111 of the suspension bolt 101, and in this state, the coupling device 103 is moved up and down to a desired position with respect to the suspension bolt 101.

その後、図１０，図１１の仮想線に示すように、一方及び他方の支持ブロック１０５，１０６を閉鎖して複数の皿ねじ１０７で結合することにより、連結装置１０３が吊りボルト１０１に固定され、梁部材１０２の位置（高さ）を調節することができる。 Thereafter, as shown by phantom lines in FIGS. 10 and 11, the connecting device 103 is fixed to the suspension bolt 101 by closing the one and the other support blocks 105 and 106 and connecting them with a plurality of flat head screws 107. The position (height) of the beam member 102 can be adjusted.

上記のような開閉式の連結装置１０３は例えば下記特許文献１に記載されている。 The open / close coupling device 103 as described above is described in, for example, Patent Document 1 below.

特開平１１−１４９２５０JP-A-11-149250

しかしながら上記の従来形式では、連結装置１０３の固定位置を変更する場合、複数の皿ねじ１０７を連結装置１０３に着脱して、一方及び他方の支持ブロック１０５，１０６を開閉する必要があるため、連結装置１０３の固定位置変更作業に手間を要するといった問題がある。 However, in the above conventional type, when the fixing position of the connecting device 103 is changed, it is necessary to attach and detach the plurality of flat head screws 107 to the connecting device 103 and open and close the one and the other support blocks 105 and 106. There is a problem that it takes time to change the fixed position of the apparatus 103.

また、連結装置１０３の支持孔１０８の孔径は吊りボルト１０１の直径に対応した所定の寸法で形成されているため、直径の多少異なる他のサイズの吊りボルト１０１に対して連結装置１０３を用いることは困難であるといった問題がある。 Moreover, since the hole diameter of the support hole 108 of the coupling device 103 is formed with a predetermined dimension corresponding to the diameter of the suspension bolt 101, the coupling device 103 is used for suspension bolts 101 of other sizes having slightly different diameters. Has the problem of being difficult.

本発明は、固定位置の変更作業が容易に行え、径の多少異なる吊りボルトにも使用可能な連結装置を提供することを目的とする。 It is an object of the present invention to provide a connecting device that can easily change the fixing position and can be used for suspension bolts having slightly different diameters.

上記目的を達成するために、本第１発明は、吊りボルトに梁部材を連結する連結装置であって、
連結フレームに、梁部材を保持する保持部と、係止部材と、案内手段とが設けられ、
保持部に保持された梁部材と係止部材との間に、吊りボルトが挿通可能な挿通部を形成し、
係止部材は、挿通部に挿通された吊りボルトを梁部材との間で挟持する固定方向と、吊りボルトから退避する固定解除方向とに移動自在であり、且つ、付勢部材によって固定方向へ付勢されているとともに、案内手段によって固定方向へ案内され、
固定方向は梁部材と係止部材との間隔が次第に縮小する斜め上方向であり、
係止部材は付勢部材の付勢力に抗して係止部材を固定解除方向へ移動させる操作部を有しているものである。 In order to achieve the above object, the first invention is a connecting device for connecting a beam member to a suspension bolt,
The connecting frame is provided with a holding portion for holding the beam member, a locking member, and a guide means,
Between the beam member held by the holding portion and the locking member, an insertion portion through which the suspension bolt can be inserted is formed,
The locking member is movable in a fixing direction in which the suspension bolt inserted through the insertion portion is sandwiched between the beam member and a fixing release direction in which the suspension bolt is retracted from the suspension bolt, and is moved in the fixing direction by the biasing member. Being urged and guided in the fixing direction by the guiding means,
The fixing direction is an obliquely upward direction in which the interval between the beam member and the locking member gradually decreases,
The locking member has an operation unit that moves the locking member in the fixing release direction against the biasing force of the biasing member.

これによると、梁部材を保持部に保持し、吊りボルトを挿通部に挿通した状態で、係止部材が、付勢部材によって固定方向へ付勢されるとともに、案内手段によって固定方向へ案内される。これにより、吊りボルトが梁部材と係止部材との間で挟持され、連結装置が吊りボルトに取付固定され、梁部材が連結装置を介して吊りボルトに連結される。 According to this, in a state where the beam member is held by the holding portion and the suspension bolt is inserted through the insertion portion, the locking member is urged in the fixing direction by the urging member and is guided in the fixing direction by the guide means. The Accordingly, the suspension bolt is sandwiched between the beam member and the locking member, the connecting device is attached and fixed to the suspension bolt, and the beam member is connected to the suspension bolt via the connection device.

また、吊りボルトに取付固定された連結装置には、自重や梁部材の重さに応じて、下向きの力が作用している。この下向きの力により連結フレームが下降しようとしても、連結フレームに対して係止部材が案内手段により固定方向（すなわち斜め上方向）へ案内されるため、係止部材が楔作用により吊りボルトに押付けられ、吊りボルトが梁部材と係止部材との間で強固に挟持され、これにより、連結装置を吊りボルトに強固に固定することができる。 Further, a downward force is applied to the coupling device attached and fixed to the suspension bolt according to its own weight or the weight of the beam member. Even if the connecting frame is lowered by this downward force, the locking member is guided to the fixing direction by the guide means with respect to the connecting frame, that is, obliquely upward, so that the locking member is pressed against the suspension bolt by the wedge action. The suspension bolt is firmly sandwiched between the beam member and the locking member, whereby the connecting device can be firmly fixed to the suspension bolt.

また、径の多少異なる他のサイズの吊りボルトであっても、梁部材と係止部材との間で吊りボルトを挟持することが可能であれば、連結装置を吊りボルトに取付固定することができる。このため、径の多少異なる他のサイズの吊りボルトに対しても連結装置を使用することができる。 In addition, even if the suspension bolts are of other sizes having slightly different diameters, if the suspension bolts can be sandwiched between the beam member and the locking member, the connecting device can be attached and fixed to the suspension bolts. it can. For this reason, the connecting device can be used for suspension bolts of other sizes having slightly different diameters.

また、操作部を手で操作して、付勢部材の付勢力に抗して係止部材を固定解除方向へ移動させることにより、係止部材が吊りボルトから退避して、梁部材と係止部材との間隔が拡大する。これにより、容易に、吊りボルトに対する連結装置の固定が解除され、連結装置を吊りボルトの長手方向へ移動させて、連結装置の位置を簡単に変えることができる。 In addition, by operating the operating portion by hand and moving the locking member in the unlocking direction against the biasing force of the biasing member, the locking member is retracted from the suspension bolt and locked with the beam member. The space between the members increases. Thereby, fixation of the coupling device with respect to the suspension bolt is easily released, and the position of the coupling device can be easily changed by moving the coupling device in the longitudinal direction of the suspension bolt.

上記のようにして連結装置の位置を変更した後、操作部から手を離すことにより、係止部材が案内手段と付勢部材の付勢力とによって固定方向へ案内され移動する。これにより、梁部材と係止部材との間隔が縮小し、吊りボルトが梁部材と係止部材との間で挟持され、連結装置が吊りボルトに固定される。これにより、連結装置の固定位置変更作業が容易に行え、梁部材の位置調節に要する手間が大幅に軽減される。 After the position of the coupling device is changed as described above, the locking member is guided and moved in the fixing direction by the guide means and the urging force of the urging member by releasing the hand from the operation portion. Thereby, the space | interval of a beam member and a locking member reduces, a suspension bolt is clamped between a beam member and a locking member, and a connection apparatus is fixed to a suspension bolt. Thereby, the fixing position changing operation of the connecting device can be easily performed, and the labor required for adjusting the position of the beam member is greatly reduced.

本第２発明における連結装置は、吊りボルトを梁部材と係止部材との間で挟持した状態で係止部材をロックするセフティロック装置が備えられているものである。
これによると、吊りボルトが梁部材と係止部材との間で挟持された状態で、セフティロック装置により係止部材をロックすることで、係止部材が不用意に固定解除方向へ移動することはなく、連結装置は吊りボルトに確実に取付固定された状態に保たれ、連結装置が吊りボルトから脱落するのを確実に防止することができるため、安全性が向上する。 The connecting device according to the second invention is provided with a safety lock device that locks the locking member in a state where the suspension bolt is sandwiched between the beam member and the locking member.
According to this, the locking member is inadvertently moved in the unlocking direction by locking the locking member with the safety lock device while the suspension bolt is sandwiched between the beam member and the locking member. However, the connecting device is securely attached and fixed to the suspension bolt, and the connecting device can be reliably prevented from falling off the suspension bolt, so that safety is improved.

本第３発明における連結装置は、案内手段は係止部材を固定方向および固定解除方向へ案内する案内穴であり、
案内穴は、下端部に形成された拘束部と、拘束部から斜め上方向へ連設された案内部とを有するＬ形状に形成され、
係止部材は、吊りボルトから退避する固定解除位置において、拘束部に拘束されるものである。 In the connecting device according to the third invention, the guide means is a guide hole for guiding the locking member in the fixing direction and the fixing release direction,
The guide hole is formed in an L shape having a restraining portion formed at the lower end portion and a guide portion provided obliquely upward from the restraining portion,
The locking member is restrained by the restraining portion at the fixed release position where it is retracted from the suspension bolt.

これによると、操作部を手で操作して、付勢部材の付勢力に抗して係止部材を固定解除方向へ移動させることにより、係止部材が案内部によって固定解除方向へ案内される。そして、係止部材を固定解除位置まで移動させて案内部から拘束部に拘束することにより、係止部材が固定解除位置に拘束された状態に保たれる。 According to this, by operating the operation part by hand and moving the locking member in the unlocking direction against the biasing force of the biasing member, the locking member is guided in the unlocking direction by the guide part. . Then, the locking member is moved to the fixing release position and restrained from the guide portion to the restraining portion, so that the locking member is kept restrained at the fixing release position.

この状態で、吊りボルトを挿通部に挿通し、梁部材を保持部に保持する。この作業の際、上記のように係止部材が固定解除位置に拘束されているため、係止部材が不用意に固定方向へ移動して作業の邪魔をすることは無く、作業が迅速に行える。 In this state, the suspension bolt is inserted into the insertion portion, and the beam member is held by the holding portion. During this work, since the locking member is restrained at the fixed release position as described above, the locking member does not inadvertently move in the fixing direction and does not disturb the work, and the work can be performed quickly. .

その後、操作部を手で操作して、係止部材を拘束部から案内部へ移動させる。これにより、係止部材が、付勢部材の付勢力により、案内部に案内されて固定方向へ移動する。このため、梁部材と係止部材との間隔が縮小し、吊りボルトが梁部材と係止部材との間で挟持され、連結装置が吊りボルトに固定される。 Thereafter, the operation part is operated by hand to move the locking member from the restraint part to the guide part. Thus, the locking member is guided by the guide portion and moved in the fixing direction by the urging force of the urging member. For this reason, the space | interval of a beam member and a latching member reduces, a suspension bolt is clamped between a beam member and a latching member, and a connection device is fixed to a suspension bolt.

本第４発明における連結装置は、係止部材は両端部よりも中央部が縮径した鼓状のこま部材を有し、
こま部材の外周面に、吊りボルトのねじ部に歯合する歯合部が形成されているものである。 In the connecting device according to the fourth aspect of the present invention, the locking member has a drum-shaped top member having a reduced diameter at the center portion rather than at both ends.
On the outer peripheral surface of the top member, a meshing portion that meshes with the thread portion of the suspension bolt is formed.

これによると、吊りボルトを梁部材と係止部材との間で挟持している際、こま部材の歯合部が吊りボルトのねじ部に確実に歯合するため、こま部材が不用意に吊りボルトを滑り下りることはなく、連結装置が吊りボルトに強固に取付固定される。 According to this, when the suspension bolt is clamped between the beam member and the locking member, the meshing portion of the top member surely meshes with the threaded portion of the suspension bolt, so that the top member is inadvertently suspended. The connecting device is firmly attached and fixed to the suspension bolt without sliding down the bolt.

以上のように本発明によると、連結装置の固定位置の変更作業が容易に行え、梁部材の位置調節に要する手間が大幅に軽減される。また、径の多少異なる吊りボルトにも使用可能である。さらに、連結装置が吊りボルトから脱落するのを確実に防止することができ、作業が迅速に行える。また、係止部材が楔作用により吊りボルトに押圧され、吊りボルトが梁部材と係止部材との間で強固に挟持されるため、連結装置を吊りボルトに強固に取付固定することができる。 As described above, according to the present invention, it is possible to easily change the fixing position of the coupling device, and the labor required for adjusting the position of the beam member is greatly reduced. It can also be used for suspension bolts with slightly different diameters. Furthermore, it is possible to reliably prevent the connecting device from falling off the suspension bolt, and work can be performed quickly. Moreover, since the locking member is pressed against the suspension bolt by the wedge action and the suspension bolt is firmly held between the beam member and the locking member, the connecting device can be firmly attached and fixed to the suspension bolt.

(1) First, as shown in FIG. 7, the operation member 31 is grasped by hand and moved in the unlocking direction B against the urging force of the spring 11, so that the locking member 10 is moved to the guide hole 22. It is guided by the guide part 24 and moves down to the fixed release position D. Then, the operation knob 31 is operated to insert the support shaft 19 of the locking member 10 into the restraining portion 23 and restrain the locking member 10 at the fixed release position D.

（２）この状態で、操作つまみ３１から手を離し、吊りボルト１を連結フレーム８内の挿通部１６に挿通し、梁部材４を保持孔９に挿通して連結フレーム８に保持する。この作業の際、上記手順（１）のように係止部材１０が固定解除位置Ｄに拘束されているため、係止部材１０が不用意に固定方向Ａへ移動して作業の邪魔をすることは無く、作業が迅速に行える。 (2) In this state, the hand is released from the operation knob 31, the suspension bolt 1 is inserted into the insertion portion 16 in the connection frame 8, and the beam member 4 is inserted into the holding hole 9 and held in the connection frame 8. During this operation, the locking member 10 is restrained to the fixing release position D as in the above procedure (1), so that the locking member 10 inadvertently moves in the fixing direction A and disturbs the operation. No, work can be done quickly.

（３）その後、操作つまみ３１を手でつかんで操作し、係止部材１０の支軸１９を拘束部２３から案内部２４へ移動させる。これにより、図２に示すように、係止部材１０が、ばね１１の付勢力により、案内部２４に案内されて固定方向Ａへ移動する。このため、梁部材４と係止部材１０との間隔Ｃが縮小し、吊りボルト１が梁部材４と係止部材１０のこま部材１８との間で挟持され、連結装置３が吊りボルト１に固定される。 (3) Thereafter, the operation knob 31 is held and operated, and the support shaft 19 of the locking member 10 is moved from the restraining portion 23 to the guide portion 24. Thereby, as shown in FIG. 2, the locking member 10 is guided by the guide portion 24 by the urging force of the spring 11 and moves in the fixing direction A. For this reason, the distance C between the beam member 4 and the locking member 10 is reduced, the suspension bolt 1 is clamped between the beam member 4 and the top member 18 of the locking member 10, and the coupling device 3 is attached to the suspension bolt 1. Fixed.

（４）その後、図５に示すように、セフティロック装置１２を連結フレーム８のねじ孔３４に螺合して締め込み、セフティロック装置１２の先端を係止部材１０のこま部材１８の外周面に当接させる。 (4) Thereafter, as shown in FIG. 5, the safety lock device 12 is screwed into the screw hole 34 of the connecting frame 8 and tightened, and the tip of the safety lock device 12 is connected to the outer peripheral surface of the top member 18 of the locking member 10. Abut.

上記の手順（１）〜（４）により、図１に示すように、梁部材４が連結装置３を介して吊りボルト１に連結される。
尚、図２に示すように、吊りボルト１に取付固定された連結装置３には、自重や梁部材４の重さに応じて、下向きの力が作用している。この下向きの力により連結フレーム８が下降しようとしても、連結フレーム８に対して係止部材１０が案内部２４により固定方向Ａ（すなわち斜め上方向）へ案内されるため、係止部材１０のこま部材１８が楔作用により吊りボルト１に押付けられ、吊りボルト１が梁部材４とこま部材１８との間で強固に挟持され、これにより、連結装置３を吊りボルト１に強固に固定することができる。 Through the above procedures (1) to (4), the beam member 4 is connected to the suspension bolt 1 via the connecting device 3 as shown in FIG.
As shown in FIG. 2, a downward force is applied to the coupling device 3 attached and fixed to the suspension bolt 1 according to its own weight or the weight of the beam member 4. Even if the connecting frame 8 is lowered by this downward force, the locking member 10 is guided in the fixing direction A (that is, obliquely upward) by the guide portion 24 with respect to the connecting frame 8. The member 18 is pressed against the suspension bolt 1 by the wedge action, and the suspension bolt 1 is firmly clamped between the beam member 4 and the top member 18, and thereby the coupling device 3 can be firmly fixed to the suspension bolt 1. it can.

この際、こま部材１８の歯合部２０が吊りボルト１の雄ねじ部２に歯合するため、こま部材１８が不用意に吊りボルト１を滑り下りることはなく、連結装置３が吊りボルト１に一段と強固に取付固定される。 At this time, since the meshing portion 20 of the top member 18 meshes with the external thread portion 2 of the suspension bolt 1, the top member 18 does not inadvertently slide down the suspension bolt 1, and the connecting device 3 is attached to the suspension bolt 1. It is more firmly attached and fixed.

また、上記手順（４）において、セフティロック装置１２の先端をこま部材１８に当接させることにより、係止部材１０がロックされ、係止部材１０が不用意に固定解除方向Ｂへ移動することはない。これにより、連結装置３は吊りボルト１に確実に取付固定された状態に保たれ、連結装置３が吊りボルト１から脱落するのを確実に防止することができるため、安全性が向上する。 Further, in the above procedure (4), the locking member 10 is locked by causing the tip of the safety lock device 12 to contact the top member 18, and the locking member 10 is carelessly moved in the unlocking direction B. There is no. As a result, the connecting device 3 is securely attached and fixed to the suspension bolt 1, and the connecting device 3 can be reliably prevented from falling off from the suspension bolt 1, thereby improving safety.

尚、万一、セフティロック装置１２に下向きの外力が作用しても、図２，図３，図５に示すように、セフティロック装置１２が備えられている下部板片２８は支持突起３５によって下方から支持されているため、上記下向きの外力によって下部板片２８が下方へ変形してしまうのを防止することができる。 Even if a downward external force acts on the safety lock device 12, the lower plate piece 28 provided with the safety lock device 12 is supported by the support protrusion 35 as shown in FIGS. 2, 3, and 5. Since it is supported from below, the lower plate piece 28 can be prevented from being deformed downward by the downward external force.

また、径の多少異なる他のサイズの吊りボルト１であっても、梁部材４と係止部材１０との間で吊りボルト１を挟持することが可能であれば、連結装置３を吊りボルト１に取付固定することができる。このため、径の多少異なる他のサイズの吊りボルト１に対しても連結装置３を使用することができる。 If the suspension bolt 1 can be sandwiched between the beam member 4 and the locking member 10 even if the suspension bolt 1 is of a different size, the coupling device 3 is connected to the suspension bolt 1. It can be attached and fixed to. For this reason, the connecting device 3 can be used for the suspension bolts 1 of other sizes having slightly different diameters.

また、吊りボルト１に対する連結装置３の固定位置を変更するときの手順を以下に説明する。
（１）先ず、図５の仮想線に示すように、セフティロック装置１２を回転操作して、セフティロック装置１２の先端を係止部材１０のこま部材１８から下方へ離間させ、係止部材１０のロックを解除する。 The procedure for changing the fixing position of the coupling device 3 with respect to the suspension bolt 1 will be described below.
(1) First, as shown by the phantom line in FIG. 5, the safety lock device 12 is rotated to separate the tip of the safety lock device 12 downward from the top member 18 of the locking member 10. Release the lock.

（２）次に、図７に示すように、操作つまみ３１を、手でつかんで、ばね１１の付勢力に抗して固定解除方向Ｂへ移動させ、係止部材１０の支軸１９を拘束部２３に挿入して、係止部材１０を固定解除位置Ｄに拘束する。これにより、係止部材１０のこま部材１８が吊りボルト１から退避して、梁部材４と係止部材１０との間隔Ｃが拡大する。このため、容易に、吊りボルト１に対する連結装置３の固定が解除され、連結装置３を吊りボルト１の長手方向（すなわち上下方向）へ移動させて、連結装置３の位置（高さ）を変えることができる。 (2) Next, as shown in FIG. 7, the operation knob 31 is grasped by hand and moved in the unlocking direction B against the biasing force of the spring 11 to restrain the support shaft 19 of the locking member 10. The locking member 10 is constrained to the fixed release position D by being inserted into the portion 23. Thereby, the top member 18 of the locking member 10 is retracted from the suspension bolt 1, and the distance C between the beam member 4 and the locking member 10 is increased. For this reason, the fixing of the connecting device 3 to the suspension bolt 1 is easily released, and the position (height) of the connecting device 3 is changed by moving the connecting device 3 in the longitudinal direction (that is, the vertical direction) of the suspension bolt 1. be able to.

（４）その後、図５の実線に示すように、セフティロック装置１２を回転操作して、セフティロック装置１２の先端を係止部材１０のこま部材１８の外周面に当接させる。
上記の手順（１）〜（４）により、連結装置３の固定位置変更作業が容易に行え、梁部材４の位置（高さ）調節に要する手間が大幅に軽減され、また、梁部材４を容易に水平に保つことが可能となる。 (4) Thereafter, as shown by the solid line in FIG. 5, the safety lock device 12 is rotated to bring the tip of the safety lock device 12 into contact with the outer peripheral surface of the top member 18 of the locking member 10.
According to the above steps (1) to (4), the fixing position changing operation of the connecting device 3 can be easily performed, and the labor required for adjusting the position (height) of the beam member 4 is greatly reduced. It becomes possible to keep it level easily.

上記実施の形態では、図６に示すように、操作部の一例として、操作つまみ３１をこま部材１８の支軸１９の両端部に備えたが、支軸１９の両端部を案内穴２２から連結フレーム８の側板１４の外方へ突出させ、操作つまみ３１の代りに、支軸１９の両端部を操作部として利用してもよい。 In the above embodiment, as shown in FIG. 6, as an example of the operation unit, the operation knob 31 is provided at both ends of the support shaft 19 of the top member 18, but both ends of the support shaft 19 are connected from the guide hole 22. The side plate 14 of the frame 8 may be protruded outward, and instead of the operation knob 31, both ends of the support shaft 19 may be used as the operation unit.

上記実施の形態では、セフティロック装置１２として、図５に示すような蝶ボルト３３を用いたが、図８に示すような六角穴付きボルト４１や図９に示すような鍋頭ボルト４２等を用いてもよい。 In the embodiment described above, the butterfly bolt 33 as shown in FIG. 5 is used as the safety lock device 12, but the hexagon socket head bolt 41 as shown in FIG. 8, the pan head bolt 42 as shown in FIG. It may be used.

上記実施の形態では、図５に示すように、係止部材１０として、鼓形状のこま部材１８を用いたが、こま部材１８の代わりに、三角形状の楔部材を用いてもよい。
上記実施の形態では、図２に示すように、係止部材１０を固定方向Ａへ案内する案内手段の一例として、案内穴２２を用いたが、案内穴２２の代りに、案内板を用いて、係止部材１０を固定方向Ａへ案内してもよい。この場合、連結フレーム８の連結板１５を案内板として利用してもよい。 In the above embodiment, as shown in FIG. 5, the drum-shaped top member 18 is used as the locking member 10, but a triangular wedge member may be used instead of the top member 18.
In the above embodiment, as shown in FIG. 2, the guide hole 22 is used as an example of the guide means for guiding the locking member 10 in the fixing direction A. However, instead of the guide hole 22, a guide plate is used. The locking member 10 may be guided in the fixing direction A. In this case, the connecting plate 15 of the connecting frame 8 may be used as a guide plate.
