Description

本発明は、作業台、及び、ステイに関する。   The present invention relates to a work table and a stay.

特許文献１には、天板と脚体との間にステイを備える作業台が開示されている。ステイは、２つの棒状の部材からなり、途中で屈曲自在である。脚体は、天板下面に平行に沿うように折り畳んだ閉脚状態と起立した開脚状態との間で開閉可能である。   Patent Document 1 discloses a work table including a stay between a top plate and a leg. The stay is composed of two rod-like members and can be bent midway. The leg body can be opened and closed between a closed leg state folded so as to be parallel to the lower surface of the top plate and an opened leg state.

特開２０１１−８４９４４号公報JP 2011-84944 A

通常、ステイは、２つの棒状の部材のなす角度を、０°から１８０°をわずかに超える角度である上限角度までの範囲に制限するストッパを備える。特許文献１に記載のステイで、脚体を開脚状態に固定させるためには、作業者は、まず、脚体を閉脚状態から開脚状態にして、２つの棒状の部材のなす角度を０°に近い角度から１８０°をわずかに下回る角度にする。次に、作業者は、２つの棒状の部材の連結部を天板の反対側に押し込んで、２つの棒状の部材のなす角度を上限角度にする。これにより、脚体に対して閉脚状態に向かわせる力が加わると、２つの棒状の部材のなす角度が上限角度から３６０°に近づくような力がステイに加わることになるが、ステイが備えるストッパによって上限角度を超えることがなく、ステイが脚体を開脚状態に固定することになる。
しかしながら、作業者は、脚体を開脚状態に固定するために、２つの棒状の部材の連結部を天板の反対側に押し込むことが必要であり、煩雑である。 Usually, the stay includes a stopper that limits the angle formed by the two rod-shaped members to a range from 0 ° to an upper limit angle that is slightly over 180 °. In order to fix the leg in the open leg state in the stay described in Patent Document 1, first, the operator changes the angle between the two rod-shaped members from the closed leg to the open leg. The angle is close to 180 ° and slightly below 180 °. Next, the operator pushes the connecting portion of the two rod-shaped members to the opposite side of the top plate, and sets the angle formed by the two rod-shaped members to the upper limit angle. As a result, when a force is applied to the leg body toward the closed leg state, a force is applied to the stay so that the angle formed by the two rod-shaped members approaches 360 ° from the upper limit angle. Therefore, the stay does not exceed the upper limit angle, and the stay fixes the leg in the open leg state.
However, it is necessary for the operator to push the connecting portion of the two bar-shaped members to the opposite side of the top plate in order to fix the leg body in the open leg state, which is complicated.

本発明は、互いに回動可能な部材を簡易に固定することを目的とする。   It is an object of the present invention to simply fix members that are rotatable relative to each other.

As shown in FIG. 1, the caster 130 is provided at the end of the leg 120 opposite to the top plate 110, and can move the work table 100 in use.

ステイ１４０は、脚部１２０を開脚姿勢に固定可能である。ステイ１４０は、第１部材１４１と、第２部材１４２と、第３部材１４３とを備える。
第１部材１４１、及び、第２部材１４２は、棒状の形状である。
第１部材１４１は、天板１１０に対して回動自在になるように、一方の端部が天板１１０の下面側に取付けられている。
第２部材１４２は、脚部１２０に対して回動自在となるように、一方の端部が脚部１２０に取付けられている。また、第２部材１４２は、第１部材１４１に対して回動自在になるように、他方の端部が、第１部材１４１における天板１１０に取付けられた側の端部とは反対側の端部に取付けられている。したがって、第１部材１４１と第２部材１４２とは、接合部分となる回転軸１４５を中心に、それぞれ回動自在である。 The stay 140 can fix the leg portion 120 to the open leg posture. The stay 140 includes a first member 141, a second member 142, and a third member 143.
The first member 141 and the second member 142 are rod-shaped.
One end of the first member 141 is attached to the lower surface side of the top plate 110 so as to be rotatable with respect to the top plate 110.
One end portion of the second member 142 is attached to the leg portion 120 so as to be rotatable with respect to the leg portion 120. In addition, the second member 142 is configured such that the other end of the second member 142 is opposite to the end of the first member 141 on the side attached to the top plate 110 so as to be rotatable with respect to the first member 141. Installed at the end. Therefore, the first member 141 and the second member 142 are each rotatable about the rotation shaft 145 serving as a joint portion.

作業台１００が使用状態であり、脚部１２０が図１に示す開脚姿勢のとき、第１部材１４１の軸線方向と第２部材１４２の軸線方向とが等しく、第１部材１４１と第２部材１４２とが直線状に並ぶ姿勢となる。
作業台１００が収納状態であり、脚部１２０が図２に示す閉脚姿勢のとき、第１部材１４１、及び、第２部材１４２は、回転軸１４５を中心に回動して、図１の姿勢と比べて互いに近接するように畳まれた姿勢となる。 When the workbench 100 is in use and the leg 120 is in the open leg position shown in FIG. 1, the axial direction of the first member 141 and the axial direction of the second member 142 are equal, and the first member 141 and the second member 142 are arranged in a straight line.
When the work table 100 is in the stowed state and the leg portion 120 is in the closed leg posture shown in FIG. 2, the first member 141 and the second member 142 are rotated around the rotation shaft 145, and the posture of FIG. Compared to the above, the postures are folded so as to be close to each other.

第３部材１４３は、第１部材１４１及び第２部材１４２の回転軸１４５を中心とした回動を規制する部材である。第３部材１４３は、筒状であり、第１部材１４１と比べて短い。第３部材１４３は、第３部材１４３の内側の中空部に棒状の第１部材１４１が通るように、第１部材１４１に取付けられている。したがって、第３部材１４３は、第１部材１４１に沿って移動可能である。本実施形態では、第３部材１４３は角筒状とするが、第３部材１４３は、円筒状等の他の形状でもよい。   The third member 143 is a member that regulates the rotation of the first member 141 and the second member 142 around the rotation shaft 145. The third member 143 has a cylindrical shape and is shorter than the first member 141. The third member 143 is attached to the first member 141 such that the rod-shaped first member 141 passes through the hollow portion inside the third member 143. Therefore, the third member 143 is movable along the first member 141. In the present embodiment, the third member 143 has a rectangular tube shape, but the third member 143 may have another shape such as a cylindrical shape.

第３部材１４３は、第１部材１４１の軸線方向と第２部材１４２の軸線方向とが等しいとき、第１位置１５０から第２位置１５１までの間を移動可能である。
第１位置１５０は、第１部材１４１と第２部材１４２とが重ならない第１部材１４１の位置である。第３部材１４３が第１位置１５０に位置するとき、第３部材１４３は、第２部材１４２を覆わず、第１部材１４１の一部のみを覆う。そして、第３部材１４３が第１位置１５０に位置するとき、第１部材１４１に対する第２部材１４２の回動を規制しない。第２位置１５１は、第１部材１４１と第２部材１４２とが重なる位置である。第３部材１４３が第２位置１５１に位置するとき、第３部材１４３は、第１部材１４１の一部、及び、第２部材１４２の一部を覆う。そして、第３部材１４３が第２位置１５１に位置するとき、第１部材１４１に対する第２部材１４２の回動を規制する。
図１、図３に示すように、第１部材１４１の軸線方向と第２部材１４２の軸線方向とが等しく、第１部材１４１と第２部材１４２とが直線状に並ぶ姿勢のとき、筒状の第３部材１４３は、第１位置１５０から第２位置１５１までの間を移動可能である。 The third member 143 can move between the first position 150 and the second position 151 when the axial direction of the first member 141 is equal to the axial direction of the second member 142.
The first position 150 is a position of the first member 141 where the first member 141 and the second member 142 do not overlap. When the third member 143 is located at the first position 150, the third member 143 does not cover the second member 142 but covers only a part of the first member 141. And when the 3rd member 143 is located in the 1st position 150, rotation of the 2nd member 142 with respect to the 1st member 141 is not controlled. The second position 151 is a position where the first member 141 and the second member 142 overlap. When the third member 143 is located at the second position 151, the third member 143 covers a part of the first member 141 and a part of the second member 142. When the third member 143 is positioned at the second position 151, the rotation of the second member 142 relative to the first member 141 is restricted.
As shown in FIGS. 1 and 3, when the axial direction of the first member 141 is equal to the axial direction of the second member 142 and the first member 141 and the second member 142 are arranged in a straight line, the cylindrical shape The third member 143 is movable between the first position 150 and the second position 151.

第２部材１４２は、突出部１４６を備える。突出部１４６は、第２部材１４２の表面から外側に突出している。突出部１４６は、第１部材１４１と第２部材１４２とが直線状に並ぶ姿勢のとき、第３部材１４３の移動方向において、第３部材１４３と重なる位置まで突出している。そして、第３部材１４３は、第２位置１５１に位置するとき、突出部１４６に接触する。したがって、第３部材１４３が第１位置１５０から第２部材１４２に向かって移動すると、第３部材１４３は突出部１４６と接触するため、第３部材１４３は、第２位置１５１で停止し、第２位置１５１よりも第２部材１４２の側には移動できない。   The second member 142 includes a protrusion 146. The protruding portion 146 protrudes outward from the surface of the second member 142. When the first member 141 and the second member 142 are arranged in a straight line, the protruding portion 146 protrudes to a position overlapping the third member 143 in the moving direction of the third member 143. When the third member 143 is located at the second position 151, the third member 143 contacts the protruding portion 146. Therefore, when the third member 143 moves from the first position 150 toward the second member 142, the third member 143 comes into contact with the protruding portion 146, so that the third member 143 stops at the second position 151, and It cannot move to the second member 142 side from the second position 151.

図１、及び、図３に示すように、第３部材１４３が第２位置１５１に位置するとき、第３部材１４３の天板１１０側の半分程度の領域が、第１部材１４１の回転軸１４５側の端部を覆っている。よって、第３部材１４３が第２位置１５１に位置するとき、第１部材１４１の一部である回転軸１４５側の端部の第２部材１４２に対する回動方向に、第３部材１４３の天板１１０側の半分程度の部分が配置されることになる。
また、第３部材１４３が第２位置１５１に位置するとき、第３部材１４３の天板１１０とは反対側の半分程度の領域が、第２部材１４２の回転軸１４５側の端部を覆っている。よって、第３部材１４３が第２位置１５１に位置するとき、第２部材１４２の少なくとも一部である回転軸１４５側の端部の第１部材１４１に対する回動方向に、第３部材１４３の天板１１０とは反対側の半分程度の部分が配置されることになる。 As shown in FIG. 1 and FIG. 3, when the third member 143 is located at the second position 151, a region about half of the third member 143 on the top plate 110 side is the rotation shaft 145 of the first member 141. Covers the side edge. Therefore, when the third member 143 is positioned at the second position 151, the top plate of the third member 143 is rotated in the rotation direction with respect to the second member 142 at the end on the rotating shaft 145 side which is a part of the first member 141. About half of the portion on the 110 side is arranged.
Further, when the third member 143 is positioned at the second position 151, the region of about half of the third member 143 opposite to the top plate 110 covers the end of the second member 142 on the rotating shaft 145 side. Yes. Therefore, when the third member 143 is positioned at the second position 151, the top of the third member 143 is in the rotational direction with respect to the first member 141 at the end on the rotating shaft 145 side which is at least a part of the second member 142. About half of the portion opposite to the plate 110 is disposed.

したがって、第３部材１４３が第２位置１５１に位置するときに、第１部材１４１、及び、第２部材１４２の少なくともいずれかに対して、回転軸１４５を中心に回動する方向の力が加わると、第１部材１４１、及び、第２部材１４２が第３部材１４３に接触する。このため、第３部材１４３が第２位置１５１に位置するときは、第１部材１４１、及び、第２部材１４２の回動が規制されるので、第１部材１４１と第２部材１４２とが直線状に並ぶ姿勢に固定される。
ステイ１４０には、第１ステイ１４０Ａと、第２ステイ１４０Ｂとがある。第１ステイ１４０Ａは、天板１１０と第１脚部１２０Ａとの間に取付けられる。第２ステイ１４０Ｂは、天板１１０と第２脚部１２０Ｂとの間に取付けられる。 Therefore, when the third member 143 is positioned at the second position 151, a force in a direction to rotate around the rotation shaft 145 is applied to at least one of the first member 141 and the second member 142. Then, the first member 141 and the second member 142 are in contact with the third member 143. For this reason, when the third member 143 is positioned at the second position 151, the rotation of the first member 141 and the second member 142 is restricted, so that the first member 141 and the second member 142 are linear. It is fixed to the posture arranged in a line.
The stay 140 includes a first stay 140A and a second stay 140B. The first stay 140A is attached between the top plate 110 and the first leg 120A. The second stay 140B is attached between the top plate 110 and the second leg 120B.

作業台１００を構成する各部には、鉄、ステンレス、及び、アルミニウムの少なくともいずれかが使われるが、こられの金属に限定されるものではなく、その他の金属や金属以外の材料を用いてもよい。
第３部材１４３の色は、第１部材１４１の色、及び、第２部材１４２の色と異なる。例えば、第１部材１４１の色、及び、第２部材１４２の色は、素材の色である銀色であり、第３部材１４３の色は、素材の色とは異なる黄色、赤色、及び、朱色の少なくともいずれかとする。第１部材１４１の色、第２部材１４２の色、及び、第３部材１４３の色には、ここで説明した色以外の色を用いてもよい。 At least one of iron, stainless steel, and aluminum is used for each part constituting the workbench 100, but it is not limited to these metals, and other metals or materials other than metals may be used. Good.
The color of the third member 143 is different from the color of the first member 141 and the color of the second member 142. For example, the color of the first member 141 and the color of the second member 142 are silver, which is the color of the material, and the color of the third member 143 is yellow, red, and vermilion different from the color of the material. At least one. You may use colors other than the color demonstrated here for the color of the 1st member 141, the color of the 2nd member 142, and the color of the 3rd member 143.

次に、作業台１００を、図２に示す収納状態から図１に示す使用状態にする方法について説明する。
まず、作業者は、脚部１２０を動かして、脚部１２０を図１に示す開脚姿勢にする。脚部１２０が開脚姿勢になると、第１部材１４１と第２部材１４２とが直線状に並ぶ。そして、第３部材１４３は、重力によって、第１位置１５０から第２位置１５１まで移動する。第３部材１４３は、第２位置１５１で第２部材１４２の突出部１４６に接触するため、第２位置１５１よりも先には移動できない。こうして、第３部材１４３によって、第１部材１４１と第２部材１４２とが直線状に並ぶ姿勢に固定されて、脚部１２０が開脚姿勢に固定される。なお、重力によらずに、作業者が、第３部材１４３を第１位置１５０から第２位置１５１まで移動させてもよい。
次に、作業者は、ロック金具１２１と連結金具１１１とを貫通するようにロックピンを通す。これにより、ロックピンによって、脚部１２０が開脚姿勢に固定される。 Next, a method for changing the workbench 100 from the storage state shown in FIG. 2 to the use state shown in FIG. 1 will be described.
First, the operator moves the leg part 120 to bring the leg part 120 into the open leg posture shown in FIG. When the leg portion 120 is in the open leg posture, the first member 141 and the second member 142 are arranged in a straight line. The third member 143 moves from the first position 150 to the second position 151 by gravity. Since the third member 143 contacts the protrusion 146 of the second member 142 at the second position 151, the third member 143 cannot move beyond the second position 151. Thus, the third member 143 fixes the first member 141 and the second member 142 in a linearly aligned posture, and the leg portion 120 is fixed in the open leg posture. Note that the operator may move the third member 143 from the first position 150 to the second position 151 without depending on gravity.
Next, the operator passes the lock pin so as to penetrate the lock fitting 121 and the connecting fitting 111. Thereby, the leg part 120 is fixed to an open leg attitude | position with a lock pin.

次に、作業台１００を、図１に示す使用状態から図２に示す収納状態にする方法について説明する。
まず、作業者は、天板１１０が下側、脚部１２０が上側になるように、作業台１００を上下逆にする。下とは重力の方向である。これにより、第３部材１４３は、重力によって、第２位置１５１から第１位置１５０まで移動する。このとき、第３部材１４３は、例えば、脚部１２０における天板１１０の側の端部の近傍まで移動する。この第３部材１４３の移動先も第１位置１５０である。なお、重力によらずに、作業者が、第３部材１４３を第２位置１５１から第１位置１５０まで移動させてもよい。
次に、作業者は、ロック金具１２１と連結金具１１１とを貫通するように通したロックピンを外す。
次に、作業者は、脚部１２０を動かして、脚部１２０を図２に示す閉脚姿勢にする。
次に、作業者は、ロック金具１２１と連結金具１１１とを貫通するようにロックピンを通す。これにより、ロックピンによって、脚部１２０が閉脚姿勢に固定される。 Next, a method for changing the workbench 100 from the use state shown in FIG. 1 to the storage state shown in FIG. 2 will be described.
First, the operator turns the work table 100 upside down so that the top plate 110 is on the lower side and the leg portion 120 is on the upper side. Below is the direction of gravity. Accordingly, the third member 143 moves from the second position 151 to the first position 150 by gravity. At this time, the 3rd member 143 moves to the vicinity of the edge part by the side of the top plate 110 in the leg part 120, for example. The destination of the third member 143 is also the first position 150. Note that the operator may move the third member 143 from the second position 151 to the first position 150 regardless of gravity.
Next, the operator removes the lock pin that has passed through the lock fitting 121 and the connecting fitting 111.
Next, the operator moves the leg 120 to bring the leg 120 into the closed leg posture shown in FIG.
Next, the operator passes the lock pin so as to penetrate the lock fitting 121 and the connecting fitting 111. Thereby, the leg part 120 is fixed to a closed leg posture by the lock pin.

以上説明したように、ステイ１４０は、天板１１０に回動自在に取付けられた第１部材１４１と、脚部１２０に回動自在に取付けられ、第１部材１４１に回動自在に取付けられた第２部材１４２と、第３部材１４３とを備える。第３部材１４３は、第１部材１４１に対する第２部材１４２の回動を規制しない第１位置１５０と第１部材１４１に対する第２部材１４２の回動を規制する第２位置１５１との間で第１部材１４１に沿って移動可能である。よって、第３部材１４３を第１部材１４１に沿って移動させるだけで、第１部材１４１に対する第２部材１４２の回動を規制したり解除したりできる。したがって、天板１１０に対する脚部１２０の姿勢を開脚姿勢に固定したり、この固定を解除したりすることを簡易に行うことができる。   As described above, the stay 140 is pivotally attached to the first member 141 that is pivotably attached to the top plate 110 and the leg portion 120, and is pivotally attached to the first member 141. A second member 142 and a third member 143 are provided. The third member 143 has a first position 150 between the first position 150 where the rotation of the second member 142 relative to the first member 141 is not restricted and the second position 151 where the rotation of the second member 142 relative to the first member 141 is restricted. It can move along one member 141. Therefore, the rotation of the second member 142 relative to the first member 141 can be restricted or released only by moving the third member 143 along the first member 141. Therefore, it is possible to easily fix the posture of the leg portion 120 with respect to the top plate 110 to the open leg posture or to release this fixation.

また、ステイ１４０は、天板１１０に回動自在に取付けられた第１部材１４１と、脚部１２０に回動自在に取付けられ、第１部材１４１に回動自在に取付けられた第２部材１４２と、第３部材１４３とを備える。第３部材１４３は、第１部材１４１の軸線方向と第２部材１４２の軸線方向とが等しいとき、第１部材１４１に沿って、第２位置１５１まで移動可能である。また、第３部材１４３が第２位置１５１に位置するとき、第１部材１４１の一部の第２部材１４２に対する回動方向に、第３部材１４３の一部が配置される。また、第３部材１４３が第２位置１５１に位置するとき、第２部材１４２の少なくとも一部の第１部材１４１に対する回動方向に、第３部材１４３の一部が配置される。   The stay 140 includes a first member 141 that is pivotably attached to the top plate 110 and a second member 142 that is pivotally attached to the leg portion 120 and pivotally attached to the first member 141. And a third member 143. The third member 143 is movable along the first member 141 to the second position 151 when the axial direction of the first member 141 is equal to the axial direction of the second member 142. Further, when the third member 143 is positioned at the second position 151, a part of the third member 143 is arranged in a rotating direction with respect to a part of the second member 142 of the first member 141. Further, when the third member 143 is positioned at the second position 151, a part of the third member 143 is arranged in a rotation direction with respect to at least a part of the second member 142 with respect to the first member 141.

脚部１２０を開脚姿勢にして、第１部材１４１の軸線方向と第２部材１４２の軸線方向とが等しくなると、重力によって、第３部材１４３が第２位置１５１に移動する。よって、第１部材１４１、及び、第２部材１４２の回動が規制されて、第１部材１４１、及び、第２部材１４２は、第１部材１４１の軸線方向と第２部材１４２の軸線方向とが等しくなる姿勢に固定されて、脚部１２０が開脚姿勢に固定される。
したがって、作業者がステイを操作して、脚部１２０を開脚姿勢に固定させる作業が不要になり、簡易に脚部１２０を開脚姿勢に固定できる。
重力によらずに、作業者が、第３部材１４３を第１位置１５０から第２位置１５１まで移動させてもよい。この場合でも、作業者は第３部材１４３を第１位置１５０から第２位置１５１までスライドさせるだけでよいので、簡易に脚部１２０を開脚姿勢に固定できる。 When the leg 120 is in the open posture and the axial direction of the first member 141 and the axial direction of the second member 142 become equal, the third member 143 moves to the second position 151 by gravity. Therefore, the rotation of the first member 141 and the second member 142 is restricted, and the first member 141 and the second member 142 are configured such that the axial direction of the first member 141 and the axial direction of the second member 142 are the same. Are fixed to the equal posture, and the leg portion 120 is fixed to the open leg posture.
This eliminates the need for the operator to operate the stay to fix the leg portion 120 in the open leg posture, and the leg portion 120 can be easily fixed in the open leg posture.
An operator may move the third member 143 from the first position 150 to the second position 151 without depending on gravity. Even in this case, since the operator only needs to slide the third member 143 from the first position 150 to the second position 151, the leg portion 120 can be easily fixed in the open leg posture.

また、脚部１２０を開脚姿勢である作業台１００を上下逆にすると、重力によって、第３部材１４３が第１位置１５０に移動する。よって、第１部材１４１、及び、第２部材１４２の回動の規制が解除されて、第１部材１４１、及び、第２部材１４２は、回動できるようになり、脚部１２０を閉脚姿勢にできる。
したがって、作業者がステイを操作することなく、第１部材１４１、及び、第２部材１４２の回動の規制を解除できる。
重力によらずに、作業者が、第３部材１４３を第２位置１５１から第１位置１５０まで移動させてもよい。この場合でも、作業者は第３部材１４３を第２位置１５１から第１位置１５０までスライドさせるだけでよいので、簡易に、第１部材１４１、及び、第２部材１４２の回動の規制を解除できる。 Further, when the work table 100 having the leg 120 in the open leg position is turned upside down, the third member 143 moves to the first position 150 by gravity. Accordingly, the restriction on the rotation of the first member 141 and the second member 142 is released, and the first member 141 and the second member 142 can be rotated, and the leg portion 120 is brought into the closed leg posture. it can.
Therefore, the restriction of the rotation of the first member 141 and the second member 142 can be released without the operator operating the stay.
The operator may move the third member 143 from the second position 151 to the first position 150 regardless of gravity. Even in this case, since the operator only has to slide the third member 143 from the second position 151 to the first position 150, the restriction on the rotation of the first member 141 and the second member 142 is easily released. it can.

また、第１部材１４１、及び、第２部材１４２は、棒状である。第３部材１４３は、筒状であり、第１部材１４１と比べて短い。そして、第３部材１４３の内側の中空部に第１部材１４１が配置されている。したがって、第３部材１４３は、重力、又は、作業者によって第１位置１５０から第２位置１５１までスムーズに移動できる。   Moreover, the 1st member 141 and the 2nd member 142 are rod-shaped. The third member 143 has a cylindrical shape and is shorter than the first member 141. The first member 141 is disposed in the hollow portion inside the third member 143. Therefore, the third member 143 can move smoothly from the first position 150 to the second position 151 by gravity or an operator.

また、第３部材１４３の色は、第１部材１４１の色、及び、第２部材１４２の色と異なる。よって、作業者は、第３部材１４３の識別が容易である。したがって、作業台１００が使用状態のときに、第３部材１４３が正しく第２位置１５１に位置するか否かの判断が容易に行える。また、作業台１００を使用状態から収納状態にするときの第３部材１４３を第２位置１５１から第１位置１５０に移動させる作業が行い易くなる。   The color of the third member 143 is different from the color of the first member 141 and the color of the second member 142. Therefore, the operator can easily identify the third member 143. Therefore, it is possible to easily determine whether or not the third member 143 is correctly positioned at the second position 151 when the work table 100 is in use. Moreover, it becomes easy to perform the work of moving the third member 143 from the second position 151 to the first position 150 when the workbench 100 is changed from the use state to the storage state.
