作業台システム１０は、所定数の作業台１００、所定数のブリッジ台車２００、所定数のブリッジ３００、手摺部３０、梯子部６０等の複数の種類の構成機材からなる。所定数の作業台１００、所定数のブリッジ台車２００、所定数のブリッジ３００を連結することで作業者が高所作業を行うことができる略矩形状の広い作業平面が形成される。
本実施形態の作業台システム１０は、略矩形状の作業平面を形成する具体的な数量として、９台の作業台１００（１００ａ～１００ｉ）、６台（６枚）のブリッジ台車２００（２００ａ～２００ｆ）、３０枚のブリッジ３００を有する。本実施形態の作業平面は、前後方向の長さが例えば７７００ｍｍ～７９００ｍｍであり、左右方向の長さが例えば５０００ｍｍ～６１００ｍｍである。このような作業平面の大きさは、作業現場がビルである場合にフロア内に位置する柱間に作業平面が収まる寸法である。 The workbench system 10 includes a plurality of types of constituent equipment, such as a predetermined number of workbenches 100, a predetermined number of bridge carts 200, a predetermined number of bridges 300, a handrail portion 30, a ladder portion 60, and the like. By connecting a predetermined number of workbenches 100, a predetermined number of bridge carts 200, and a predetermined number of bridges 300, a generally rectangular wide work plane is formed on which a worker can work at height.
The workbench system 10 of this embodiment includes nine workbenches 100 (100a to 100i) and six bridge carts 200 (200a to 100i), which form a substantially rectangular work plane. 200f), and has 30 bridges 300. The working plane of this embodiment has a length in the front-back direction of, for example, 7700 mm to 7900 mm, and a length in the left-right direction of, for example, 5000 mm to 6100 mm. The size of such a work plane is such that the work plane can fit between pillars located in a floor when the work site is a building.

なお、９台の作業台１００ａ～１００ｉはそれぞれ同様の構成であり、区別する必要がない場合には以下では単に作業台１００という。また、６台のブリッジ台車２００ａ～２００ｆはそれぞれ同様の構成であり、区別する必要がない場合には以下では単にブリッジ台車２００という。また、３０枚のブリッジ３００はそれぞれ同様の構成である。 Note that the nine workbenches 100a to 100i have the same configuration, and will be simply referred to as workbench 100 below unless it is necessary to distinguish them. Further, the six bridge carts 200a to 200f have the same configuration, and will be simply referred to as bridge carts 200 below unless it is necessary to distinguish them. Furthermore, each of the 30 bridges 300 has the same configuration.

具体的に、作業台システム１０は前後方向に沿った３つの列ユニット２０ａ～２０ｃが作業台１００とブリッジ台車２００とから構成される。この列ユニット２０ａ～２０ｃは、作業台システム１０を構成する上で基準となる。３つの列ユニット２０ａ～２０ｃはそれぞれ、後側から前側に向かって作業台１００、ブリッジ台車２００、作業台１００、ブリッジ台車２００、作業台１００の順に配置される。本実施形態では、平面視において、作業台１００とブリッジ台車２００とは大きさが略同一であり、前後方向（長手方向）が左右方向（短手方向）よりも長い略矩形状である。より詳細には、作業台１００およびブリッジ台車２００は、前後方向の長さと左右方向の長さとの比が略３：２の関係である。 Specifically, the workbench system 10 includes three row units 20a to 20c along the front-rear direction, each consisting of a workbench 100 and a bridge truck 200. The row units 20a to 20c serve as a reference for configuring the workbench system 10. The three row units 20a to 20c are arranged in the following order from the rear side to the front: workbench 100, bridge truck 200, workbench 100, bridge truck 200, and workbench 100. In this embodiment, the workbench 100 and the bridge truck 200 have substantially the same size in plan view, and have a substantially rectangular shape in which the front-back direction (longitudinal direction) is longer than the left-right direction (short-side direction). More specifically, the workbench 100 and the bridge truck 200 have a relationship in which the ratio of the length in the front-rear direction to the length in the left-right direction is approximately 3:2.

また、作業台システム１０は、左右方向に間隔を空けてそれぞれ平行に配置した３つの列ユニット２０ａ～２０ｃの間に隙間なく複数のブリッジ３００を架け渡して構成される。本実施形態では、平面視において、ブリッジ３００は前後方向（短手方向）が左右方向（長手方向）よりも短い略矩形状である。より詳細には、ブリッジ３００は前後方向の長さと左右方向の長さとの比が略１：３の関係である。また、作業台１００およびブリッジ台車２００の前後方向の長さとブリッジ３００の左右方向の長さとが略同一であり、作業台１００およびブリッジ台車２００の前後方向の長さとブリッジ３００の前後方向の長さとの比が略３：１の関係である。したがって、離れて配置された作業台１００の間に３枚のブリッジ３００を架け渡すことができ、離れて配置されたブリッジ台車２００の間に３枚のブリッジ３００を架け渡すことができる。
結果として、列ユニット２０ａと列ユニット２０ｂとの間に１５枚のブリッジ３００が配置され、列ユニット２０ｂと列ユニット２０ｃとの間に１５枚のブリッジ３００が配置される。 Further, the workbench system 10 is configured by having a plurality of bridges 300 bridged without gaps between three row units 20a to 20c arranged in parallel with each other at intervals in the left-right direction. In this embodiment, when viewed from above, the bridge 300 has a substantially rectangular shape in which the front-back direction (short-side direction) is shorter than the left-right direction (longitudinal direction). More specifically, the ratio of the length of the bridge 300 in the front-rear direction to the length in the left-right direction is approximately 1:3. Further, the lengths of the workbench 100 and the bridge truck 200 in the front-rear direction and the lengths of the bridge 300 in the left-right direction are approximately the same, and the lengths of the workbench 100 and the bridge truck 200 in the front-rear direction and the lengths of the bridge 300 in the front-rear direction are approximately the same. The ratio is approximately 3:1. Therefore, three bridges 300 can be spanned between the workbenches 100 that are spaced apart, and three bridges 300 can be spanned between the bridge carts 200 that are spaced apart.
As a result, 15 bridges 300 are arranged between row unit 20a and row unit 20b, and 15 bridges 300 are arranged between row unit 20b and row unit 20c.

手摺部３０は、取り付け取り外し可能であって、作業平面の外周縁に沿って取り付けることで作業平面の外周縁を取り囲む。作業者が作業平面で作業しているときに作業者の身体の一部が手摺部３０に接触することで、作業者は作業平面の端であることを認識できる。手摺部３０は、複数の手摺を有する。
本実施形態の手摺部３０は、長手手摺３１と短手手摺３２とを有し、作業平面の外周縁を取り囲む具体的な数量として１３台の長手手摺３１と７台の短手手摺３２とを有する。 The handrail portion 30 is attachable and detachable, and surrounds the outer circumferential edge of the working plane by being attached along the outer circumferential edge of the working plane. When a part of the worker's body comes into contact with the handrail portion 30 while the worker is working on the work plane, the worker can recognize that the worker is at the edge of the work plane. The handrail section 30 has a plurality of handrails.
The handrail part 30 of this embodiment has a longitudinal handrail 31 and a short handrail 32, and the specific number of longitudinal handrails 31 and seven short handrails 32 surrounding the outer periphery of the work plane is 13. have

長手手摺３１は、平面視で、作業台１００、ブリッジ台車２００およびブリッジ３００の長手方向の長さと略同一の長さである。長手手摺３１は、作業平面の外周に位置する作業台１００、ブリッジ台車２００およびブリッジ３００のうちそれぞれ長手側の端部に取り付けられる。ただし、図１Ａに示す作業台１００ｃでは長手側の端部に梯子部６０を取り付けるために長手手摺３１ではなく短手手摺３２が取り付けられる。
また、短手手摺３２は、平面視で、作業台１００およびブリッジ台車２００の短手方向の長さと略同一の長さである。短手手摺３２は、作業平面の外周に位置する作業台１００およびブリッジ台車２００のうちそれぞれ短手側の端部に取り付けられる。 The longitudinal handrail 31 has substantially the same length as the length of the workbench 100, the bridge truck 200, and the bridge 300 in the longitudinal direction in plan view. The longitudinal handrail 31 is attached to the longitudinal end of the workbench 100, the bridge truck 200, and the bridge 300, which are located on the outer periphery of the work plane. However, in the workbench 100c shown in FIG. 1A, a short handrail 32 is attached instead of a long handrail 31 in order to attach a ladder portion 60 to the longitudinal end.
Further, the short handrail 32 has substantially the same length as the length of the workbench 100 and the bridge truck 200 in the short direction when viewed from above. The short handrail 32 is attached to the short end of the workbench 100 and the bridge truck 200, which are located on the outer periphery of the work plane.

梯子部６０は、作業平面の外周縁に取り付けることで作業者が作業平面と床面との間を昇降可能にする。
本実施形態の作業台システム１０は、具体的な数量として１台の梯子部６０を有する。梯子部６０は、平面視で、作業台１００およびブリッジ３００の短手方向の長さよりも適度に短い長さである。梯子部６０は、作業平面の外周に位置する作業台１００、ブリッジ台車２００またはブリッジ３００のうち長手側の端部あるいは短手側の端部に取り付けられる。 The ladder section 60 is attached to the outer periphery of the work plane to allow the worker to move up and down between the work plane and the floor.
The workbench system 10 of this embodiment has one ladder section 60 as a specific quantity. The ladder portion 60 has a length that is appropriately shorter than the lengths of the workbench 100 and the bridge 300 in the lateral direction in plan view. The ladder section 60 is attached to a longitudinal end or a short end of the workbench 100, the bridge truck 200, or the bridge 300 located on the outer periphery of the work plane.

次に、作業台１００の構成について図４を参照して説明する。図４は、作業台１００の構成の一例を示す平面図、正面図、側面図である。
作業台１００は、天板部１１０と、脚部１３０と、回動部１５０と、走行部１８０とを有する。
天板部１１０は、高所作業を行う作業者の足場としての役割を担う。天板部１１０は、平面視で、前後方向に長い略矩形状である。本実施形態では、天板部１１０の前後方向（長手方向）の長さが例えば略１５５０ｍｍであり、左右方向（短手方向）の長さが例えば略１０１０ｍｍである。また、天板部１１０は、床面から例えば略１０００ｍｍ～略１５００ｍｍの高さである。なお、天板部１１０は、前後方向と左右方向との長さが略等しくてもよい。 Next, the configuration of the workbench 100 will be described with reference to FIG. 4. FIG. 4 is a plan view, a front view, and a side view showing an example of the configuration of the workbench 100.
The workbench 100 includes a top plate section 110, leg sections 130, a rotating section 150, and a running section 180.
The top plate portion 110 serves as a scaffold for workers who work at heights. The top plate portion 110 has a substantially rectangular shape that is long in the front-rear direction when viewed from above. In this embodiment, the length of the top plate portion 110 in the front-rear direction (longitudinal direction) is, for example, approximately 1550 mm, and the length in the left-right direction (short direction) is, for example, approximately 1010 mm. Further, the top plate portion 110 has a height of, for example, approximately 1000 mm to approximately 1500 mm from the floor surface. Note that the top plate portion 110 may have substantially the same length in the front-rear direction and the left-right direction.

天板部１１０は、作業面となる表面に滑り止め用の複数の突起を有する。また、天板部１１０は、外周縁に近接した位置に連結バー１１４を有する。また、天板部１１０は、外周縁に近接した位置に複数の連結孔１１８を有する。連結孔１１８は、天板部１１０の長手側の端部（第１の端部）と短手側の端部（第２の端部）とにそれぞれ位置する。連結孔１１８は、長手側の端部に例えば６つ、短手側の端部に例えば４つ形成される。連結孔１１８は、ブリッジ台車２００の連結ピン２２１、ブリッジ３００の連結ピン３２１、または、他の作業台１００を直に隣接させたときに他の作業台１００の連結バー１１４と連結するための孔である。
また、天板部１１０は、外周縁に近接した位置に、手摺部３０を取り付けるための複数の手摺用孔１２５を有する。手摺用孔１２５は、天板部１１０の長手側の端部（第１の端部）と短手側の端部（第２の端部）とにそれぞれ位置する。手摺用孔１２５は、長手側の端部に例えば６つ、短手側の端部に例えば２つ形成される。なお、図４では、天板部１１０の長手側の端部に長手手摺３１を取り付けるための２つの手摺用孔１２５のみを図示している。ここで、短手側の端部の２つの手摺用孔１２５のピッチは、長手側の端部の２つの手摺用孔１２５のピッチと異なっている。 The top plate portion 110 has a plurality of anti-slip protrusions on the surface that serves as a work surface. Further, the top plate portion 110 has a connecting bar 114 at a position close to the outer periphery. Further, the top plate portion 110 has a plurality of connecting holes 118 at positions close to the outer periphery. The connecting holes 118 are located at the longitudinal end (first end) and the short end (second end) of the top plate portion 110, respectively. For example, six connecting holes 118 are formed at the longitudinal end, and four connecting holes 118 are formed at the short end. The connection hole 118 is a hole for connecting with the connection pin 221 of the bridge truck 200, the connection pin 321 of the bridge 300, or the connection bar 114 of another workbench 100 when the other workbench 100 is directly adjacent. It is.
Moreover, the top plate part 110 has a plurality of handrail holes 125 for attaching the handrail part 30 at positions close to the outer peripheral edge. The handrail holes 125 are located at the longitudinal end (first end) and the short end (second end) of the top plate portion 110, respectively. For example, six handrail holes 125 are formed at the longitudinal end and two, for example, at the short end. In addition, in FIG. 4, only two handrail holes 125 for attaching the longitudinal handrail 31 to the longitudinal end of the top plate part 110 are illustrated. Here, the pitch of the two handrail holes 125 at the shorter end is different from the pitch of the two handrail holes 125 at the longer end.

脚部１３０は、天板部１１０の荷重を支持したり、天板部１１０で作業する作業者の荷重を支持したりする役割を担う。また、脚部１３０は、天板部１１０の下側で連結され、天板部１１０に対して回動可能である。脚部１３０が回動することで、脚部１３０が天板部１１０と重なり合うようにして折り畳まれる。具体的に、脚部１３０は４本の脚部材１３１ａ～１３１ｄを有する。なお、図４では、脚部材１３１ｂは脚部材１３１ａ、１３１ｄによって隠れるために図示されていない。脚部材１３１ａ～１３１ｄは、それぞれ天板部１１０の４隅に近接した位置から床面に向かって延びる。 The legs 130 play the role of supporting the load of the top plate 110 and the load of an operator working on the top plate 110. Further, the leg portions 130 are connected below the top plate portion 110 and are rotatable relative to the top plate portion 110. By rotating the leg portion 130, the leg portion 130 is folded so as to overlap the top plate portion 110. Specifically, the leg portion 130 has four leg members 131a to 131d. Note that in FIG. 4, the leg member 131b is not shown because it is hidden by the leg members 131a and 131d. The leg members 131a to 131d each extend toward the floor from positions close to the four corners of the top plate portion 110.

また、脚部材１３１ａと脚部材１３１ｂとの間、および、脚部材１３１ｃと脚部材１３１ｄとの間には、水平方向に沿って横桟部材１３７が横架される。横桟部材１３７が脚部材１３１ａと脚部材１３１ｂとの間、および、脚部材１３１ｃと脚部材１３１ｄとの間に横架されることで、脚部材１３１ａと脚部材１３１ｂが一つのユニット、すなわち第１の脚体とし、脚部材１３１ｃと脚部材１３１ｄとが一つのユニット、すなわち第２の脚体として構成される。したがって、脚部１３０が天板部１１０に対して回動する場合には、脚部材１３１ａと脚部材１３１ｂとが一体で回動し、脚部材１３１ｃと脚部材１３１ｄとが一体で回動する。
なお、脚部材１３１ａと脚部材１３１ｂ、および、脚部材１３１ｃと脚部材１３１ｄは、高さ方向に段階的に伸縮することができる。 Moreover, a horizontal beam member 137 is horizontally suspended between the leg member 131a and the leg member 131b and between the leg member 131c and the leg member 131d along the horizontal direction. The horizontal member 137 is horizontally suspended between the leg member 131a and the leg member 131b and between the leg member 131c and the leg member 131d, so that the leg member 131a and the leg member 131b form one unit, that is, the leg member 131a and the leg member 131b. The leg member 131c and the leg member 131d are configured as one unit, that is, a second leg body. Therefore, when the leg portion 130 rotates with respect to the top plate portion 110, the leg member 131a and the leg member 131b rotate together, and the leg member 131c and the leg member 131d rotate together.
Note that the leg members 131a and 131b, and the leg members 131c and 131d can be expanded and contracted in stages in the height direction.

また、本実施形態の作業台１００は、開脚姿勢では脚部１３０が完全に鉛直方向に延出しているのではなく、安定性を向上させるために鉛直方向に対して傾斜している。すなわち、作業台１００を左右方向に沿って見たときに、一対の脚体は上端から下端に向かうしたがって、互いに離れるように傾斜している。 Further, in the workbench 100 of this embodiment, the legs 130 do not completely extend vertically in the open leg posture, but are inclined with respect to the vertical direction in order to improve stability. That is, when the workbench 100 is viewed along the left-right direction, the pair of legs are inclined away from each other as they go from the upper end to the lower end.

回動部１５０は、脚部１３０を天板部１１０に対して回動させる役割を担う。脚部１３０が回動部１５０を介して天板部１１０に対して回動することで、脚部１３０が下側に向かって延びる開脚姿勢と、脚部１３０が天板部１１０に重なり合って折り畳まれる閉脚姿勢とに変化する。具体的には、回動部１５０は４つの回動体１５１ａ～１５１ｄを有する。なお、図４では、回動体１５１ｂ、１５１ｄはそれぞれ回動体１５１ａ、１５１ｃによって隠れるために図示されていない。回動体１５１ａ～１５１ｄは、それぞれ脚部材１３１ａ～１３１ｄと天板部１１０との間に配置される。
ここで、回動体１５１ａ、１５１ｂの回動支点Ｐ１は、回動体１５１ｃ、１５１ｄの回動支点Ｐ２よりも上側、すなわち天板部１１０側にオフセットして位置する。 The rotating part 150 plays a role of rotating the leg part 130 with respect to the top plate part 110. By rotating the legs 130 with respect to the top plate 110 via the rotation unit 150, the legs 130 can be placed in an open leg position extending downward, and the legs 130 can overlap the top plate 110. It changes to a folded closed leg posture. Specifically, the rotating section 150 has four rotating bodies 151a to 151d. Note that in FIG. 4, the rotating bodies 151b and 151d are not shown because they are hidden by the rotating bodies 151a and 151c, respectively. The rotating bodies 151a to 151d are arranged between the leg members 131a to 131d and the top plate portion 110, respectively.
Here, the pivot point P1 of the rotating bodies 151a and 151b is located above the pivot point P2 of the rotating bodies 151c and 151d, that is, offset to the top plate portion 110 side.

走行部１８０は、天板部１１０および脚部１３０を支持しながら作業台１００を任意の位置に移動させる役割を担う。走行部１８０は、脚部１３０の下側に連結される。具体的には、走行部１８０は４つのキャスター１８１ａ～１８１ｄを有する。なお、図４では、キャスター１８１ｂはキャスター１８１ａ、１８１ｄによって隠れるために図示されていない。キャスター１８１ａ～１８１ｄは、それぞれ脚部材１３１ａ～１３１ｄの下端に旋回可能に連結される。また、キャスター１８１ａ～１８１ｄは、それぞれ作業者の操作に応じて車輪の回転を固定することができるストッパ付キャスターである。作業者は高所作業を行う場合には、走行部１８０のキャスター１８１ａ～１８１ｄのペダルを操作して車輪の回転を固定させることで、作業台１００が移動せずに安全に高所作業を行うことができる。 The traveling section 180 plays a role of moving the workbench 100 to an arbitrary position while supporting the top plate section 110 and the legs 130. The running part 180 is connected to the lower side of the leg part 130. Specifically, the running section 180 has four casters 181a to 181d. Note that the caster 181b is not shown in FIG. 4 because it is hidden by the casters 181a and 181d. Casters 181a-181d are pivotally connected to the lower ends of leg members 131a-131d, respectively. Furthermore, each of the casters 181a to 181d is a caster with a stopper that can fix the rotation of the wheel according to the operator's operation. When working at heights, the worker operates the pedals of the casters 181a to 181d of the traveling section 180 to fix the rotation of the wheels, thereby safely performing the work at heights without the workbench 100 moving. be able to.

次に、ブリッジ台車２００の構成について図５を参照して説明する。図５は、ブリッジ台車２００の構成の一例を示す平面図、正面図、側面図である。
ブリッジ台車２００は、前後方向に離れて配置された作業台１００の天板部１１０に架け渡される。また、ブリッジ台車２００は、単に高所作業を行うための足場となるだけではなく、作業台システム１０の構成機材を積載可能な運搬台車として機能する。ブリッジ台車２００は、第１のブリッジの一例に対応する。 Next, the configuration of the bridge truck 200 will be described with reference to FIG. 5. FIG. 5 is a plan view, a front view, and a side view showing an example of the configuration of the bridge truck 200.
The bridge truck 200 spans over the top plate portion 110 of the workbench 100 that is spaced apart from each other in the front-rear direction. Furthermore, the bridge trolley 200 not only serves as a scaffold for performing work at high places, but also functions as a transport vehicle capable of loading the components of the workbench system 10. Bridge truck 200 corresponds to an example of a first bridge.

ブリッジ台車２００は、本体部２１０と、走行部２３０とを有する。
本体部２１０は、高所作業を行う作業者の足場としての役割を担う。また、本体部２１０は、ブリッジ台車２００を運搬台車として機能させる場合に作業台１００を積載するときの積載部としての役割を担う。本体部２１０は、平面視で、前後方向に長い略矩形状である。本実施形態では、本体部２１０の前後方向（長手方向）の長さが例えば略１５５０ｍｍであり、左右方向（短手方向）の長さが例えば略１０１０ｍｍである。ブリッジ台車２００の本体部２１０の大きさと、作業台１００の天板部１１０の大きさとは略同一である。ただし、本体部２１０の大きさと天板部１１０の大きさとは、略同一である場合に限られない。また、本体部２１０は、前後方向と左右方向との長さが略等しくてもよい。 Bridge truck 200 has a main body portion 210 and a traveling portion 230.
The main body portion 210 serves as a scaffold for workers who work at heights. Further, the main body portion 210 plays a role as a loading portion when loading the workbench 100 when the bridge truck 200 functions as a transport truck. The main body portion 210 has a substantially rectangular shape that is long in the front-rear direction when viewed from above. In this embodiment, the length of the main body portion 210 in the front-rear direction (longitudinal direction) is, for example, approximately 1550 mm, and the length in the left-right direction (short direction) is, for example, approximately 1010 mm. The size of the main body portion 210 of the bridge truck 200 and the size of the top plate portion 110 of the workbench 100 are approximately the same. However, the size of the main body part 210 and the size of the top plate part 110 are not limited to being substantially the same. Further, the main body portion 210 may have substantially the same length in the front-rear direction and the left-right direction.

本体部２１０は、作業面となる表面に滑り止め用の複数の突起を有する。また、本体部２１０は、外周縁に近接した位置に複数の連結孔２１８を有する。連結孔２１８は、長手側の端部に例えば６つ形成される。連結孔２１８はブリッジ３００の連結ピン３２１と連結するための孔である。
また、本体部２１０は、外周縁に近接した位置であって長手側の端部に、手摺部３０を取り付けるための複数の手摺用孔２２５を有する。手摺用孔２２５は、長手側の端部に例えば６つ形成される。なお、図５では、本体部２１０の長手側の端部に長手手摺３１を取り付けるための２つの手摺用孔２２５のみを図示している。ここで、図５に示す長手側の端部の２つの手摺用孔２２５のピッチは、図４に示す長手側の端部の２つの手摺用孔１２５のピッチと略同一である。
また、本体部２１０は、作業台１００と連結する側である短手側の端部に連結ピン２２１を有する。具体的には、連結ピン２２１は、短手側の端部（前端部および後端部）のそれぞれ両端に設けられる。連結ピン２２１は、本体部２１０の短手側の端部（前端部および後端部）からそれぞれ前側および後側に向かって延出する板状のブラケット２２２に取り付けられる。連結ピン２２１はブラケット２２２の下面から下側に向かって突出する。連結ピン２２１をそれぞれ作業台１００の連結孔１１８に上側から挿入することにより、ブリッジ台車２００と作業台１００とが連結される。ここで、連結ピン２２１およびブラケット２２２は、連結部の一例に対応する。 The main body portion 210 has a plurality of anti-slip protrusions on the surface that serves as a work surface. Further, the main body portion 210 has a plurality of connecting holes 218 at positions close to the outer periphery. For example, six connecting holes 218 are formed at the longitudinal end. The connecting hole 218 is a hole for connecting with the connecting pin 321 of the bridge 300.
Further, the main body portion 210 has a plurality of handrail holes 225 for attaching the handrail portion 30 at a position close to the outer peripheral edge and at a longitudinal end portion. For example, six handrail holes 225 are formed at the longitudinal end. Note that FIG. 5 shows only two handrail holes 225 for attaching the longitudinal handrail 31 to the longitudinal end of the main body portion 210. Here, the pitch of the two handrail holes 225 at the longitudinal end shown in FIG. 5 is approximately the same as the pitch of the two handrail holes 125 at the longitudinal end shown in FIG.
Further, the main body portion 210 has a connecting pin 221 at the shorter end that is connected to the workbench 100 . Specifically, the connecting pins 221 are provided at both ends of the short side ends (front end and rear end). The connecting pin 221 is attached to a plate-shaped bracket 222 that extends from the shorter end portions (front end portion and rear end portion) of the main body portion 210 toward the front side and the rear side, respectively. The connecting pin 221 protrudes downward from the lower surface of the bracket 222. The bridge carriage 200 and the workbench 100 are connected by inserting the connection pins 221 into the connection holes 118 of the workbench 100 from above. Here, the connecting pin 221 and the bracket 222 correspond to an example of a connecting portion.

走行部２３０は、ブリッジ台車２００を運搬台車として機能させる場合に本体部２１０および積荷の荷重を支持しながら床面を走行する役割を担う。走行部２３０は、本体部２１０の下側であって、４隅に配置される複数（４つ）のキャスター２３１ａ～２３１ｄを有する。なお、図５では、キャスター２３１ｂはキャスター２３１ａ、２３１ｄによって隠れるために図示されていない。
キャスター２３１ａ～２３１ｄは本体部２１０の下側に取り付けられる。キャスター２３１ａ～２３１ｄは、鉛直方向に沿った旋回軸Ｏの軸線回りに旋回可能である。図５では、車輪２３３が前後方向を向いた状態であるが、車輪２３３が旋回軸Ｏの軸線回りに旋回することで、ブリッジ台車２００は前側に限られず、前後左右を含め任意の方向に走行することができる。 The running section 230 plays the role of running on the floor while supporting the load of the main body section 210 and the cargo when the bridge trolley 200 functions as a transporting trolley. The running section 230 has a plurality of (four) casters 231a to 231d arranged at four corners on the lower side of the main body section 210. Note that in FIG. 5, the caster 231b is not shown because it is hidden by the casters 231a and 231d.
The casters 231a to 231d are attached to the lower side of the main body 210. The casters 231a to 231d are rotatable around a pivot axis O along the vertical direction. In FIG. 5, the wheels 233 are oriented in the front-rear direction, but by turning the wheels 233 around the pivot axis O, the bridge trolley 200 is not limited to the front, but can travel in any direction including front, rear, left, and right. can do.

キャスター２３１ａ～２３１ｄは、作業者の操作に応じてブレーキを掛けたり、ブレーキを解除したりすることができるブレーキ付キャスターである。具体的には、キャスター２３１ａ～２３１ｄは、車輪２３３と、支持部としてのフォーク部材２３４と、ブレーキペダル２３５を有する。フォーク部材２３４は、車輪２３３を回転可能に支持する。ブレーキペダル２３５は、フォーク部材２３４に対して上下方向に揺動可能である。ブレーキペダル２３５は、先端部に足で踏み込むための操作部２３６を有する。作業者がブレーキ時に操作部２３６を下側に踏み込むように操作することで、車輪２３３の外周面が押圧され、車輪２３３にブレーキが掛かる。なお、作業者は更に操作部２３６を踏み込むことで、車輪２３３はブレーキが掛かった状態に保持される。 The casters 231a to 231d are casters with brakes that can apply or release the brakes according to the operator's operation. Specifically, the casters 231a to 231d have wheels 233, a fork member 234 as a support, and a brake pedal 235. The fork member 234 rotatably supports the wheel 233. The brake pedal 235 is vertically swingable with respect to the fork member 234. The brake pedal 235 has an operating section 236 at its tip for stepping on with a foot. When the operator depresses the operating portion 236 downward during braking, the outer peripheral surface of the wheel 233 is pressed, and the wheel 233 is braked. Note that the wheel 233 is maintained in a braked state by further depressing the operating portion 236 by the operator.

なお、図５は、ブレーキが掛かっていない状態（ブレーキ解除時の状態）である。図５に示すように、ブリッジ台車２００を走行させたときに後側となるキャスター２３１ａ、２３１ｂは、ブレーキペダル２３５の操作部２３６が本体部２１０の後端よりも後側に位置して露出している。
また、操作部２３６は、ブレーキ解除時であって車輪２３３が前後方向を向いた状態では、平面視において連結ピン２２１およびブラケット２２２と重ならないように位置する。したがって、作業者はブレーキを掛ける必要がある場合には、連結ピン２２１およびブラケット２２２に干渉されることなく容易に操作部２３６を踏み込むことができる。 Note that FIG. 5 shows a state in which the brake is not applied (a state when the brake is released). As shown in FIG. 5, the casters 231a and 231b, which are on the rear side when the bridge truck 200 is running, have the operating part 236 of the brake pedal 235 located on the rear side of the rear end of the main body part 210 and exposed. ing.
Further, when the brake is released and the wheel 233 faces in the front-rear direction, the operating portion 236 is located so as not to overlap the connecting pin 221 and the bracket 222 in a plan view. Therefore, when the operator needs to apply the brake, he or she can easily step on the operating portion 236 without being interfered with by the connecting pin 221 and the bracket 222.

次に、ブリッジ３００の構成について図６を参照して説明する。図６は、ブリッジ３００の構成の一例を示す平面図、正面図、側面図である。

The main body portion 310 serves as a scaffold for workers who work at heights. The main body portion 310 has a substantially rectangular shape that is long in the left-right direction when viewed from above. In this embodiment, the length of the main body portion 310 in the front-back direction (short direction) is, for example, approximately 500 mm, and the length in the left-right direction (short direction) is, for example, approximately 1530 mm. Note that the main body portion 310 may have substantially the same length in the front-rear direction and the left-right direction.

Further, the main body portion 310 has a plurality of handrail holes 325 for attaching the handrail portion 30 at a position close to the outer peripheral edge and at a longitudinal end portion. For example, six handrail holes 325 are formed at the longitudinal end. In addition, in FIG. 6, only two handrail holes 325 for attaching the longitudinal handrail 31 to the longitudinal end of the main body part 310 are illustrated. Here, the pitch of the two handrail holes 325 at the longitudinal end shown in FIG. 6 is the same as the pitch of the two handrail holes 225 at the longitudinal end shown in FIG. The pitch is approximately the same as the pitch of the two handrail holes 125 in the section.

また、本体部３１０は、作業台１００あるいはブリッジ台車２００と連結する側である短手側の端部に連結ピン３２１を有する。具体的には、連結ピン３２１は、短手側の端部（右端部および左端部）のそれぞれ両端に設けられる。連結ピン３２１は、本体部３１０の短手側の端部（右端部および左端部）からそれぞれ右側および左側に向かって延出する板状のブラケット３２２に取り付けられる。連結ピン３２１はブラケット３２２の下面から下側に向かって突出する。連結ピン３２１をそれぞれ作業台１００の連結孔１１８あるいはブリッジ台車２００の連結孔２１８に上側から挿入することにより、作業台１００あるいはブリッジ台車２００と連結される。ここで、連結ピン３２１およびブラケット３２２は、連結部の一例に対応する。 Further, the main body portion 310 has a connecting pin 321 at the short end, which is the side that is connected to the workbench 100 or the bridge truck 200. Specifically, the connecting pins 321 are provided at both ends of the short side ends (right end and left end). The connecting pin 321 is attached to a plate-shaped bracket 322 that extends from the shorter ends (right end and left end) of the main body 310 toward the right and left sides, respectively. The connecting pin 321 protrudes downward from the lower surface of the bracket 322. The connecting pin 321 is inserted into the connecting hole 118 of the workbench 100 or the connection hole 218 of the bridge truck 200 from above, respectively, to connect with the workbench 100 or the bridge truck 200. Here, the connecting pin 321 and the bracket 322 correspond to an example of a connecting portion.

次に、手摺部３０の構成について図７、図８を参照して説明する。なお、長手手摺３１と短手手摺３２とは長さが異なるだけで略同一の構成であることから、長手手摺３１について主に説明する。また、以下では長手手摺３１を作業台１００の天板部１１０に取り付ける場合を中心に説明するが、ブリッジ台車２００の本体部２１０あるいはブリッジ３００の本体部３１０に取り付ける場合も同様である。
図７（ａ）～（ｃ）は、長手手摺３１の平面図、正面図、側面図である。なお、図７（ｂ）は、長手手摺３１を作業領域から見た図である。作業領域とは、作業平面の上方の空間であって、平面視で作業平面と重なり合う空間をいうものとする。図８は、長手手摺３１の分解斜視図である。 Next, the configuration of the handrail portion 30 will be explained with reference to FIGS. 7 and 8. In addition, since the longitudinal handrail 31 and the short handrail 32 have substantially the same configuration except for their lengths, the longitudinal handrail 31 will be mainly explained. Further, although the case where the longitudinal handrail 31 is attached to the top plate part 110 of the workbench 100 will be mainly explained below, the case where it is attached to the main body part 210 of the bridge truck 200 or the main body part 310 of the bridge 300 is also the same.
7(a) to (c) are a plan view, a front view, and a side view of the longitudinal handrail 31. Note that FIG. 7(b) is a diagram of the longitudinal handrail 31 viewed from the work area. The work area is a space above the work plane, and is a space that overlaps the work plane in plan view. FIG. 8 is an exploded perspective view of the longitudinal handrail 31.

長手手摺３１は、２つの支柱部材３３、上桟部材３６、中桟部材３７、巾木部材３８、２つの支持部材４３、２つの当接部材５０、２つの挿入ピン５５を有する。上桟部材３６は、第２の横部材の一例に対応する。中桟部材３７は、第１の横部材の一例に対応する。巾木部材３８は、第３の横部材の一例に対応する。 The longitudinal handrail 31 has two support members 33 , an upper crosspiece member 36 , a middle crosspiece member 37 , a baseboard member 38 , two support members 43 , two abutment members 50 , and two insertion pins 55 . The upper rail member 36 corresponds to an example of a second horizontal member. The middle member 37 corresponds to an example of a first horizontal member. The baseboard member 38 corresponds to an example of a third horizontal member.

支柱部材３３は、上桟部材３６、中桟部材３７、巾木部材３８を支持する。支柱部材３３は、略上下方向に沿って直線状に延びる略棒状である。本実施形態では、支柱部材３３の長さが例えば略１０００ｍｍである。また、長手手摺３１が天板部１１０に取り付けられたときに天板部１１０の表面から支柱部材３３の上端までが例えば略８００ｍｍ～略１０００ｍｍの高さである。支柱部材３３は、上桟部材３６および中桟部材３７を支持する第１支柱部３４と、巾木部材３８を支持する第２支柱部３５とを有する。第１支柱部３４と第２支柱部３５とは略上下方向に沿うように固定される。本実施形態では、第１支柱部３４の長さは、第２支柱部３４の長さよりも長い。 The support member 33 supports an upper cross member 36, a middle cross member 37, and a baseboard member 38. The support member 33 has a substantially rod shape that extends linearly along the substantially vertical direction. In this embodiment, the length of the support member 33 is approximately 1000 mm, for example. Further, when the longitudinal handrail 31 is attached to the top plate part 110, the height from the surface of the top plate part 110 to the upper end of the column member 33 is, for example, about 800 mm to about 1000 mm. The strut member 33 includes a first strut portion 34 that supports an upper crosspiece member 36 and a middle crosspiece member 37, and a second strut portion 35 that supports a baseboard member 38. The first support portion 34 and the second support portion 35 are fixed substantially along the vertical direction. In this embodiment, the length of the first support portion 34 is longer than the length of the second support portion 34.

第１支柱部３４および第２支柱部３５は、例えば、断面が中空の略矩形状である。ここで、第１支柱部３４と第２支柱部３５とは異なる材質であって、第１支柱部３４は第２支柱部３５よりも撓み易い材質が用いられる。また、第１支柱部３４は第２支柱部３５よりも剛性が低い。具体的に、第１支柱部３４は例えば合成樹脂製であり、第２支柱部３５は例えばアルミニウム合金製である。第２支柱部３５は、第１支柱部３４内に外周が嵌め込まれた状態でネジやリベット（ブラインドリベットを含む）等により固定される。ただし、支柱部材３３は、単一の部材により構成されていてもよい。この場合には、支柱部材３３は、天板部１１０よりも撓み易い材質、例えば合成樹脂製にすることができる。また、支柱部材３３は、間隔を空けて複数（２つ）配置される。また、支柱部材３３の上端には、樹脂製の保護キャップが取り付けられる。 The first support portion 34 and the second support portion 35 have, for example, a hollow, substantially rectangular cross section. Here, the first support portion 34 and the second support portion 35 are made of different materials, and the first support portion 34 is made of a material that is more flexible than the second support portion 35. Further, the first support portion 34 has lower rigidity than the second support portion 35. Specifically, the first support portion 34 is made of, for example, synthetic resin, and the second support portion 35 is made of, for example, an aluminum alloy. The second support section 35 is fixed with a screw, a rivet (including a blind rivet), or the like, with the outer periphery fitted into the first support section 34 . However, the strut member 33 may be composed of a single member. In this case, the support member 33 can be made of a material that is more flexible than the top plate portion 110, for example, synthetic resin. Moreover, a plurality (two) of the support members 33 are arranged at intervals. Further, a protective cap made of resin is attached to the upper end of the support member 33.

上桟部材３６は、間隔を空けた２つの支柱部材３３によって支持される。上桟部材３６は、横方向（略水平方向）に沿って直線状に延びる略棒状である。上桟部材３６は、長さが天板部１１０の長手方向の長さと略等しい。上桟部材３６は、例えば、断面が中空あるいは中実の略矩形状である。ここで、上桟部材３６は、第１支柱部３４と同じ材質であり、例えば合成樹脂製である。ただし、上桟部材３６は、第１支柱部３４よりも撓みにくい材質、例えばアルミニウム合金製であってもよい。また、上桟部材３６は、支柱部材３３の第１支柱部３４の上端部に固定される。また、上桟部材３６の両端には、それぞれ樹脂製の保護キャップが取り付けられる。 The upper crosspiece member 36 is supported by two support members 33 spaced apart from each other. The upper crosspiece member 36 has a substantially rod shape that extends linearly in the lateral direction (substantially horizontal direction). The length of the upper rail member 36 is approximately equal to the length of the top plate portion 110 in the longitudinal direction. The upper rail member 36 has, for example, a hollow or solid substantially rectangular cross section. Here, the upper rail member 36 is made of the same material as the first support portion 34, and is made of, for example, synthetic resin. However, the upper beam member 36 may be made of a material that is less flexible than the first support portion 34, for example, an aluminum alloy. Further, the upper crosspiece member 36 is fixed to the upper end portion of the first support portion 34 of the support member 33. Furthermore, protective caps made of resin are attached to both ends of the upper crosspiece member 36, respectively.

中桟部材３７は、間隔を空けた２つの支柱部材３３によって支持される。中桟部材３７は、横方向（略水平方向）に沿って直線状に延びる略棒状である。中桟部材３７は、長さが天板部１１０の長手方向の長さと略等しい。すなわち、中桟部材３７と上桟部材３６との長さは略等しい。中桟部材３７は、例えば、断面が中空あるいは中実の略矩形状である。ここで、中桟部材３７は、第１支柱部３４と同じ材質であり、例えば合成樹脂製である。ただし、中桟部材３７は、第１支柱部３４よりも撓みにくい材質、例えばアルミニウム合金製であってもよい。また、中桟部材３７は、支柱部材３３の上端部よりも下側に離れた位置に固定される。中桟部材３７は、上桟部材３６よりも下側であって、巾木部材３８よりも上側に位置する。また、中桟部材３７の両端には、それぞれ樹脂製の保護キャップが取り付けられる。 The middle crosspiece member 37 is supported by two support members 33 spaced apart from each other. The middle crosspiece member 37 has a substantially rod shape that extends linearly in the lateral direction (substantially horizontal direction). The length of the middle crosspiece member 37 is approximately equal to the length of the top plate portion 110 in the longitudinal direction. That is, the lengths of the middle crosspiece member 37 and the upper crosspiece member 36 are approximately equal. The middle crosspiece member 37 has, for example, a hollow or solid substantially rectangular cross section. Here, the middle beam member 37 is made of the same material as the first support portion 34, and is made of, for example, synthetic resin. However, the middle beam member 37 may be made of a material that is less flexible than the first support portion 34, for example, an aluminum alloy. Further, the middle crosspiece member 37 is fixed at a position further below and away from the upper end portion of the support member 33.

巾木部材３８は、横方向（略水平方向）に沿って直線状に延びる略棒状である。巾木部材３８は、長さが２つの支柱部材３３の間隔と略等しい。すなわち、巾木部材３８は、２つの支柱部材３３の間に架け渡されるように固定される。巾木部材３８は、例えば、断面が中空あるいは中実の略矩形状であり、アルミニウム合金製である。また、巾木部材３８は、中桟部材３７よりも下側であって、支柱部材３３の下端部よりも上側に離れた位置に固定される。 The baseboard member 38 has a substantially rod shape that extends linearly in the lateral direction (substantially horizontal direction). The length of the baseboard member 38 is approximately equal to the distance between the two support members 33 . That is, the baseboard member 38 is fixed so as to span between the two support members 33. The baseboard member 38 has, for example, a hollow or solid substantially rectangular cross section, and is made of aluminum alloy. Further, the baseboard member 38 is fixed at a position below the middle crosspiece member 37 and above the lower end of the support member 33.

On the other hand, the insertion hole 46b communicates with the handrail hole 125 formed at the short side end of the top plate part 110 when the short handrail 32 is attached to the short side end of the top plate part 110. It is a hole. In this way, by forming the insertion holes 46a and 46b for attaching the long handrail 31 and the short handrail 32 in the support part 44 of the support member 43, the support member 43 can be attached to either the long handrail 31 or the short handrail 32. It can also be used for standardization of parts.

The contact member 50 corresponds to an example of a mounting portion. The contact member 50 is located at the lower end of the column member 33. The abutting member 50 includes two fixing parts 51 fixed to the side surfaces of the lower end of the column member 33, an extending part 52 extending from the fixing part 51 in a substantially horizontal direction, and a position at the tip of the extending part 52. The contact portion 53 has a contact portion 53. The contact member 50 is made of aluminum alloy or iron, for example. The two fixing parts 51 are fixed to the lower end part of the pillar member 33 with screws, rivets, etc. in such a manner that they sandwich the second pillar part 35 of the pillar member 33 from both sides. The extension part 52 is arranged so that when the longitudinal handrail 31 is attached to the top plate part 110 of the workbench 100, it reaches inside the top plate part 110 without interfering with the end of the top plate part 110. It extends horizontally and then diagonally upwards. The contact portion 53 is located at the tip of the extension portion 52 and comes into contact with the top plate portion 110 from below within the top plate portion 110 when the longitudinal handrail 31 is attached to the top plate portion 110 of the workbench 100. .

挿入ピン５５は、支持部材４３の支持部４４の挿入孔４６ａ、４６ｂに挿入されるピンである。挿入ピン５５は、離脱しないように例えば紐状部材によって支柱部材３３に繋がれている。 The insertion pin 55 is a pin inserted into the insertion holes 46 a and 46 b of the support portion 44 of the support member 43 . The insertion pin 55 is connected to the support member 33 by, for example, a string-like member so as not to come off.

次に、上述した作業台システム１０の組み立て方法について説明する。
まず、作業者は基準となる、前後方向に沿った３つの列ユニット２０ａ～２０ｃを組み立てる。具体的には、作業台１００ａ～１００ｃ、作業台１００ｄ～１００ｆ、作業台１００ｇ～１００ｉのそれぞれ長手方向を前後方向にして、前後方向（一方向）に一定の間隔で離して配置する。 Next, a method of assembling the workbench system 10 described above will be explained.
First, an operator assembles three row units 20a to 20c along the front-rear direction, which serve as a reference. Specifically, the workbenches 100a to 100c, the workbenches 100d to 100f, and the workbenches 100g to 100i are arranged so that their longitudinal directions are in the front-rear direction and are spaced apart from each other at regular intervals in the front-rear direction (one direction).

次に、作業者は前後に離れた作業台１００の天板部１１０の間にブリッジ台車２００を架け渡す。すなわち、作業台１００ａ、１００ｄ、１００ｇと作業台１００ｂ、１００ｅ、１００ｈとの間にブリッジ台車２００ａ、２００ｃ、２００ｅを架け渡し、作業台１００ｂ、１００ｅ、１００ｈと作業台１００ｃ、１００ｆ、１００ｉとの間にブリッジ台車２００ｂ、２００ｄ、２００ｆを架け渡す。
具体的には、ブリッジ台車２００の本体部２１０の連結ピン２２１をそれぞれ、作業台１００の連結孔１１８に挿入する。したがって、ブリッジ台車２００が作業台１００と連結される。このとき、ブリッジ台車２００の走行部２３０、すなわちキャスター２３１ａ～２３１ｄと床面との間には空間が形成される。 Next, the worker places the bridge cart 200 between the top plate portions 110 of the work benches 100 that are separated from each other in the front and back. That is, bridge carts 200a, 200c, 200e are installed between workbenches 100a, 100d, 100g and workbenches 100b, 100e, 100h, and bridge carts 200a, 200c, 200e are installed between workbenches 100b, 100e, 100h and workbenches 100c, 100f, 100i. Bridge carts 200b, 200d, and 200f are placed over the bridge.
Specifically, the connecting pins 221 of the main body 210 of the bridge truck 200 are respectively inserted into the connecting holes 118 of the workbench 100. Therefore, the bridge truck 200 is connected to the workbench 100. At this time, a space is formed between the running portion 230 of the bridge truck 200, that is, the casters 231a to 231d, and the floor surface.

次に、作業者は左右方向（他方向）に一定の間隔で離して配置した３つの列ユニット２０ａ～２０ｃの間に複数のブリッジ３００を架け渡す。すなわち、作業台１００ａ、１００ｂ、１００ｃと作業台１００ｄ、１００ｅ、１００ｆとの間にブリッジ３００を架け渡し、作業台１００ｄ、１００ｅ、１００ｆと作業台１００ｇ、１００ｈ、１００ｉとの間にブリッジ３００を架け渡す。また、ブリッジ台車２００ａ、２００ｂとブリッジ台車２００ｃ、２００ｄとの間にブリッジ３００を架け渡し、ブリッジ台車２００ｃ、２００ｄとブリッジ台車２００ｅ、２００ｆとの間にブリッジ３００を架け渡す。
具体的には、ブリッジ３００の本体部３１０の連結ピン３２１をそれぞれ、作業台１００の連結孔１１８あるいはブリッジ台車２００の連結孔２１８に挿入する。したがって、ブリッジ３００が隣接する作業台１００およびブリッジ台車２００と連結される。
このように作業台１００、ブリッジ台車２００、ブリッジ３００を連結することにより、作業者が高所作業する作業平面が形成される。このとき、ブリッジ３００と床面との間には空間が形成される。ここで、ブリッジ３００は前後方向に１５枚が配置されることから、１５枚のブリッジ３００と床面との間には前後方向に沿った長い空間が形成され、この長い空間を、仮設資機材を収容するための空間として利用することができる。 Next, the worker bridges the plurality of bridges 300 between the three row units 20a to 20c arranged at a constant interval in the left-right direction (the other direction). That is, the bridge 300 is installed between the workbenches 100a, 100b, 100c and the workbenches 100d, 100e, 100f, and the bridge 300 is installed between the workbenches 100d, 100e, 100f and the workbenches 100g, 100h, 100i. hand over. Further, a bridge 300 is installed between the bridge carts 200a, 200b and the bridge carts 200c, 200d, and a bridge 300 is installed between the bridge carts 200c, 200d and the bridge carts 200e, 200f.
Specifically, the connecting pins 321 of the main body 310 of the bridge 300 are inserted into the connecting holes 118 of the workbench 100 or the connecting holes 218 of the bridge carriage 200, respectively. Therefore, the bridge 300 is connected to the adjacent work platform 100 and bridge truck 200.
By connecting the workbench 100, bridge truck 200, and bridge 300 in this manner, a work plane on which a worker works at height is formed. At this time, a space is formed between the bridge 300 and the floor surface. Here, since 15 bridges 300 are arranged in the front-rear direction, a long space along the front-rear direction is formed between the 15 bridges 300 and the floor, and this long space can be used for temporary materials and equipment. It can be used as a space to accommodate.

次に、作業者は手摺部３０を作業平面の外周縁に取り付ける。具体的に、長手手摺３１を、作業台１００ａ、ブリッジ台車２００ａ、作業台１００ｂ、ブリッジ台車２００ｂのそれぞれ左側の端部、作業台１００ｇ、ブリッジ台車２００ｅ、作業台１００ｈ、ブリッジ台車２００ｆ、作業台１００ｉの右側の端部に取り付ける。また、長手手摺３１を、作業平面の前側に位置するブリッジ３００の前端部、作業平面の後側に位置するブリッジ３００の後端部に取り付ける。更に、短手手摺３２を、作業台１００ａ、１００ｄ、１００ｇの後端部、作業台１００ｃ、１００ｆ、１００ｉの前端部、作業台１００ｃの左側の端部に取り付ける。 Next, the worker attaches the handrail portion 30 to the outer peripheral edge of the work plane. Specifically, the longitudinal handrail 31 is located at the left end of the workbench 100a, the bridge cart 200a, the workbench 100b, and the bridge cart 200b, the workbench 100g, the bridge cart 200e, the workbench 100h, the bridge cart 200f, and the workbench 100i. Attach it to the right end of the Further, the longitudinal handrail 31 is attached to the front end of the bridge 300 located on the front side of the work plane and the rear end of the bridge 300 located on the rear side of the work plane. Furthermore, short handrails 32 are attached to the rear ends of the workbenches 100a, 100d, and 100g, the front ends of the workbenches 100c, 100f, and 100i, and the left end of the workbench 100c.

ここで、長手手摺３１を作業台１００の天板部１１０に取り付ける場合について図９および図１０を参照して説明する。
図９は、作業台１００ａの長手側の端部である左側の端部に長手手摺３１を取り付け、作業台１００ａの短手側の端部である後側の端部に短手手摺３２を取り付ける場合を示す斜視図である。
図１０は、図９において作業台１００ａの長手側の端部である左側の端部に長手手摺３１を取り付けた状態でＩ－Ｉ線を略鉛直方向に切断して、矢印方向から見た断面図である。 Here, the case where the longitudinal handrail 31 is attached to the top plate portion 110 of the workbench 100 will be described with reference to FIGS. 9 and 10.
In FIG. 9, a longitudinal handrail 31 is attached to the left end, which is the longitudinal end of the workbench 100a, and a short handrail 32 is attached to the rear end, which is the shorter end of the workbench 100a. It is a perspective view which shows a case.
FIG. 10 shows a cross section taken along the line II in a substantially vertical direction and seen in the direction of the arrow with the longitudinal handrail 31 attached to the left end, which is the longitudinal end of the workbench 100a in FIG. It is a diagram.

長手手摺３１を天板部１１０に取り付けるには、作業者は、長手手摺３１の下側を天板部１１０に近づけるように斜めにした状態で長手手摺３１を天板部１１０に近づける。次に、作業者は、当接部材５０の先端を天板部１１０の下部に形成されたリブ１２６（図１０を参照）に挿入して引っ掛けた後に、当接部材５０の先端を中心にして長手手摺３１を起こすように回動させる。長手手摺３１の支柱部材３３が略上下方向になることで、支持部材４３の支持部４４が天板部１１０の表面に載置される。このとき、支持部４４の挿入孔４６ａと手摺用孔１２５とが連通する。その後、作業者は、挿入孔４６ａおよび手摺用孔１２５に挿入ピン５５を挿入することで、長手手摺３１を天板部１１０に取り付けることができる。なお、支持部４４の挿入孔４６ａは長孔であることから、長手手摺３１が天板部１１０の外周縁に沿って幾分ズレていても、支持部４４の挿入孔４６ａと手摺用孔１２５とを連通させることができる。
ここでは、長手手摺３１を作業台１００の天板部１１０に取り付ける場合について説明したが、長手手摺３１または短手手摺３２を、作業台１００の天板部１１０、ブリッジ台車２００の本体部２１０、ブリッジ３００の本体部３１０に取り付ける場合も同様である。 To attach the longitudinal handrail 31 to the top plate part 110, an operator brings the longitudinal handrail 31 close to the top plate part 110 while tilting the lower side of the longitudinal handrail 31 so as to bring it closer to the top plate part 110. Next, the operator inserts and hooks the tip of the contact member 50 into the rib 126 (see FIG. 10) formed at the bottom of the top plate portion 110, and then rotates the tip of the contact member 50 as the center. Rotate the longitudinal handrail 31 so as to raise it. The support portion 44 of the support member 43 is placed on the surface of the top plate portion 110 because the support member 33 of the longitudinal handrail 31 is oriented substantially vertically. At this time, the insertion hole 46a of the support portion 44 and the handrail hole 125 communicate with each other. After that, the operator can attach the longitudinal handrail 31 to the top plate part 110 by inserting the insertion pin 55 into the insertion hole 46a and the handrail hole 125. In addition, since the insertion hole 46a of the support part 44 is a long hole, even if the longitudinal handrail 31 is slightly shifted along the outer periphery of the top plate part 110, the insertion hole 46a of the support part 44 and the handrail hole 125 can be communicated with.
Here, the case where the longitudinal handrail 31 is attached to the top plate part 110 of the workbench 100 has been described, but the longitudinal handrail 31 or the short handrail 32 can be attached to the top plate part 110 of the workbench 100, the main body part 210 of the bridge trolley 200, The same applies when attaching to the main body 310 of the bridge 300.

次に、作業者は梯子部６０を作業平面の外周縁に取り付ける。具体的には、梯子部６０を作業台１００ｃの左側の端部に取り付ける。なお、梯子部６０を取り付ける位置は適宜、変更することができ、梯子部６０の取り付け位置に応じて短手手摺３２の取り付け位置を変更することができる。 Next, the worker attaches the ladder section 60 to the outer peripheral edge of the work plane. Specifically, the ladder section 60 is attached to the left end of the workbench 100c. Note that the position at which the ladder part 60 is attached can be changed as appropriate, and the position at which the short handrail 32 is attached can be changed depending on the position at which the ladder part 60 is attached.

このように組み立てられた作業台システム１０では、手摺部３０により作業平面を取り囲むことができるので、作業者は安全に高所作業を行うことができる。
ここで、本実施形態の長手手摺３１および短手手摺３２は、作業領域から見て、上桟部材３６および中桟部材３７の両端部が２つの支柱部材３３の外側に位置する。すなわち、上桟部材３６および中桟部材３７の両端部が２つの支柱部材３３の間に位置するのではなく、支柱部材３３を横方向に超えるように突出している。したがって、上桟部材３６および中桟部材３７の端部を、隣りの長手手摺３１または隣りの短手手摺３２の端部に近接させることができるので、隣り合う手摺の間の隙間を少なくすることができる。 In the workbench system 10 assembled in this manner, the work surface can be surrounded by the handrail portion 30, so that the worker can safely work at height.
Here, in the longitudinal handrail 31 and the short handrail 32 of this embodiment, both ends of the upper rail member 36 and the middle rail member 37 are located outside the two support members 33 when viewed from the work area. That is, both ends of the upper crosspiece member 36 and the middle crosspiece member 37 are not located between the two strut members 33, but protrude beyond the strut members 33 in the lateral direction. Therefore, the ends of the upper rail member 36 and the middle rail member 37 can be brought close to the ends of the adjacent long handrail 31 or the adjacent short handrail 32, thereby reducing the gap between the adjacent handrails. I can do it.

手摺部３０が取り付けられた状態では、図８の二点鎖線で示すように、隣り合う長手手摺３１または短手手摺３２の上桟部材３６および中桟部材３７の端部同士が略同一高さで対向することで端部間の隙間を少なくできる。このように、隙間を少なくできることで、作業者が作業平面で作業しているときに作業者の身体の一部が、上桟部材３６および中桟部材３７に接触しやすくなる。
なお、長手手摺３１および短手手摺３２は更に、作業領域から見て、上桟部材３６および中桟部材３７の両端部が２つの支持部材４３あるいは２つの支柱部材３３の外側に位置することが好ましい。 When the handrail portion 30 is attached, as shown by the two-dot chain line in FIG. By facing each other, the gap between the ends can be reduced. By reducing the gap in this way, a part of the worker's body can easily come into contact with the upper rail member 36 and the middle rail member 37 when the worker is working on the work plane.
Furthermore, in the long handrail 31 and the short handrail 32, both ends of the upper rail member 36 and the middle rail member 37 may be located on the outside of the two support members 43 or the two support members 33 when viewed from the work area. preferable.

また、図１０に示すように、本実施形態の長手手摺３１および短手手摺３２は、上桟部材３６および中桟部材３７が２つの支柱部材３３よりも作業台１００の作業領域の内側寄りに位置する。具体的には、支柱部材３３と天板部１１０とは上下方向に略重なり合わないが、上桟部材３６および中桟部材３７と天板部１１０とは上下方向に略重なり合っている。したがって、作業者の身体の一部が、上桟部材３６または中桟部材３７に接触しやすくなるので、作業者は作業平面の端付近で作業している場合に早い段階で作業平面の端であることを認識できる。
一方、巾木部材３８は上桟部材３６および中桟部材３７よりも作業台１００の作業領域の外側寄りに位置する。具体的には、図８に示すように、巾木部材３８は２つの支柱部材３３の間に位置する。したがって、作業台１００の天板部１１０の表面が巾木部材３８によって覆われるのを抑制でき、天板部１１０の作業平面を広く確保することができる。 Further, as shown in FIG. 10, in the longitudinal handrail 31 and the short handrail 32 of this embodiment, the upper rail member 36 and the middle rail member 37 are located closer to the inside of the work area of the workbench 100 than the two support members 33. To position. Specifically, the support member 33 and the top plate portion 110 do not substantially overlap each other in the vertical direction, but the upper rail member 36 and the middle rail member 37 and the top plate portion 110 substantially overlap in the vertical direction. Therefore, a part of the worker's body is likely to come into contact with the upper crosspiece member 36 or the middle crosspiece member 37, so that when the operator is working near the edge of the work plane, the worker can quickly reach the edge of the work plane. I can recognize something.
On the other hand, the baseboard member 38 is located closer to the outside of the work area of the workbench 100 than the upper rail member 36 and the middle rail member 37 are. Specifically, as shown in FIG. 8, the baseboard member 38 is located between the two support members 33. Therefore, it is possible to prevent the surface of the top plate part 110 of the workbench 100 from being covered by the baseboard member 38, and it is possible to secure a wide working surface of the top plate part 110.

また、支柱部材３３は少なくとも一部、例えば長さの半分以上が撓み易い材質である。したがって、作業者が作業領域の内側から外側に向かって長手手摺３１および短手手摺３２にもたれ掛かるように接触した場合には、支柱部材３３が撓むことで、長手手摺３１および短手手摺３２が作業領域の外側に向かうように傾斜する。すなわち、長手手摺３１および短手手摺３２は、上側になるほど作業領域の外側に位置するように傾斜する。このように、支柱部材３３を撓ませて長手手摺３１および短手手摺３２を傾斜させることで、もたれ掛かったときの力を支柱部材３３が吸収する。したがって、もたれ掛かったときの力は、支柱部材３３から作業台１００の天板部１１０、ブリッジ台車２００の本体部２１０またはブリッジ３００の本体部３１０に伝達されるのを抑制でき、作業台１００等が傾倒するのを防止することができる。
また、上桟部材３６および中桟部材３７が撓み易い材質であることから、上桟部材３６および中桟部材３７でも同様に作業者がもたれ掛かったときの力を吸収することができる。 Further, at least a portion of the support member 33, for example, more than half of the length thereof, is made of a material that is easily bent. Therefore, when a worker comes into contact with the long handrail 31 and the short handrail 32 from the inside to the outside of the work area so as to lean against the long handrail 31 and the short handrail 32, the support member 33 bends and the long handrail 31 and the short handrail 32 tilts toward the outside of the work area. That is, the long handrail 31 and the short handrail 32 are inclined so that the upper side thereof is located outside the working area. In this way, by bending the support member 33 and inclining the long handrail 31 and the short handrail 32, the support member 33 absorbs the force when leaning against it. Therefore, the force when leaning back can be suppressed from being transmitted from the support member 33 to the top plate part 110 of the workbench 100, the main body part 210 of the bridge truck 200, or the main body part 310 of the bridge 300, and the workbench 100, etc. can be prevented from leaning.
Moreover, since the upper crosspiece member 36 and the middle crosspiece member 37 are made of a material that is easily bent, the upper crosspiece member 36 and the middle crosspiece member 37 can similarly absorb the force when the operator leans back.

また、支柱部材３３は、上側に位置する第１の支持部３４が下側に位置する第２の支持部３５よりも剛性が低い。換言すると、支柱部材３３は、下側に位置する第２の支持部３５が上側に位置する第１の支持部３４よりも剛性が高い。このように下側の剛性を高くすることで支柱部材３３が撓むときに支柱部材３３自体が破断しないようにすることができる。なお、第１の支持部３４および第２の支持部３５は、剛性または撓み易さを材質によって変更する場合に限られず、形状によって変更してもよい。 Further, in the support member 33, the first support portion 34 located on the upper side has lower rigidity than the second support portion 35 located on the lower side. In other words, in the support member 33, the second support portion 35 located on the lower side has higher rigidity than the first support portion 34 located on the upper side. By increasing the rigidity of the lower side in this way, it is possible to prevent the support member 33 itself from breaking when the support member 33 is bent. Note that the rigidity or flexibility of the first support part 34 and the second support part 35 is not limited to changing depending on the material, but may be changed depending on the shape.

なお、本実施形態では、作業台システム１０を組み立てる前であって、作業台システム１０の構成機材を倉庫等に保管する場合、ブリッジ台車２００に構成機材を積載させた状態で保管することができる。各ブリッジ台車２００ａ～２００ｆには、作業者が取り扱い易いようにそれぞれ種類の異なる構成機材を振り分けて積載することが好ましい。このように、ブリッジ台車２００に作業台システム１０の構成機材を積載した状態で保管することで、ブリッジ台車２００が運搬台車として機能することから、容易に倉庫から出庫することができる。また、倉庫内で作業台システム１０の保管場所を変更する場合でも、容易に保管場所を変更することができる。 In addition, in this embodiment, before assembling the workbench system 10, when the constituent equipment of the workbench system 10 is stored in a warehouse etc., the constituent equipment can be stored in a state where the bridge trolley 200 is loaded with the constituent equipment. . It is preferable that different types of component equipment be distributed and loaded on each of the bridge carts 200a to 200f so that they can be easily handled by workers. In this way, by storing the components of the workbench system 10 loaded on the bridge truck 200, the bridge truck 200 functions as a transport truck, so that it can be easily taken out of the warehouse. Moreover, even when changing the storage location of the workbench system 10 in a warehouse, the storage location can be easily changed.
