(First embodiment)
FIG. 1 is a perspective view showing an example of the configuration of the workbench system 10. As shown in FIG. FIG. 2 is a front view showing an example of the configuration of the workbench system 10. As shown in FIG. For ease of explanation, each figure shows the front side as Fr, the rear side as Rr, the right side as R, and the left side as L as necessary.
The workbench system 10 of this embodiment includes a plurality of (for example, two) workbench 100 (100a, 100b), a workbench bridge (referred to as a bridge in this embodiment) 200, and the like.

The workbench 100a and the workbench 100b are installed in the same direction. Moreover, the workbench 100a and the workbench 100b are separated by a certain distance. The workbench 100 of the present embodiment is assumed to have a height of, for example, approximately 1000 mm to approximately 1500 mm from the floor surface to the top plate portion 110 described later.
On the other hand, the bridge 200 is arranged to bridge between the short side end of the workbench 100a and the short side end of the workbench 100b. The bridge 200 functions as a so-called scaffold. There is no member supporting the bridge 200 between the bridge 200 and the floor surface, and the worktables 100a and 100b support the bridge 200. FIG.
In the workbench system 10 of the present embodiment, the workbench 100a, the bridge 200, and the workbench 100b are arranged in a straight line along the longitudinal direction without gaps. It is a configuration suitable for performing high-place work.

Next, specific configurations of the workbench 100 and the bridge 200 will be described.
First, the configuration of the workbench 100 will be described. In addition, since the work table 100a and the work table 100b have the same configuration, the work table 100a and the work table 100b will be described without distinguishing between them.
FIG. 3 is a front view showing an example of the configuration of the workbench 100. As shown in FIG.
The workbench 100 has a top plate portion 110 , leg portions 130 , a rotating portion 150 and a traveling portion 180 .
The top plate part 110 plays a role as a scaffolding for workers who work at heights. The top plate portion 110 has a substantially rectangular shape elongated in the front-rear direction when viewed from above. In this embodiment, the front-rear direction (longitudinal direction) of the top plate portion 110 is approximately 1500 mm long, and the left-right direction (lateral direction) is approximately 1000 mm long, for example. However, the top plate portion 110 may have substantially the same length in the front-rear direction and in the left-right direction. The top plate portion 110 has a plurality of projections similar to the later-described projections 213 of the bridge 200 on the work surface. The top plate portion 110 also has a connecting bar 114 at a position close to the outer peripheral edge on the surface (see FIG. 14 described later). Further, the top plate portion 110 has a plurality of connecting holes 118 similar to the connecting holes 218 described later of the bridge 200 at positions close to the outer periphery on the surface (see FIG. 14 described later). The connecting holes 118 are located at the outer peripheral edge of the top plate portion 110 on the short side and the outer peripheral edge on the long side. The connecting hole 118 is a hole for connecting with a later-described connecting pin 221 of the bridge 200 or a connecting bar 114 of another adjacent workbench 100 .

The leg portion 130 plays a role of supporting the load of the top plate portion 110 and supporting the load of the worker working on the top plate portion 110 . Further, the leg portion 130 is connected to the lower side of the top plate portion 110 and is rotatable with respect to the top plate portion 110 . By rotating the leg portion 130 , the leg portion 130 is folded so as to overlap with the top plate portion 110 . Specifically, the leg portion 130 has four leg members 131a to 131d. Note that the leg members 131b and 131d are not shown in FIG. 3 because they are hidden by the leg members 131a and 131c, respectively. The leg members 131a to 131d extend toward the floor surface from positions close to the four corners of the top plate portion 110, respectively.

Cross-linking members 137 extend horizontally between the leg members 131a and 131b and between the leg members 131c and 131d. The horizontal member 137 is bridged between the leg members 131a and 131b and between the leg members 131c and 131d, so that the leg members 131a and 131b form one unit, that is, the first unit. The leg member 131c and the leg member 131d constitute one unit, that is, the second leg. Therefore, when the leg portion 130 rotates with respect to the top plate portion 110, the leg members 131a and 131b rotate together, and the leg members 131c and 131d rotate together. A contact member 138 is provided outside the leg members 131a and 131b. The abutting member 138 is a portion that abuts on another work table 100 when the leg portion 130 is folded and another work table 100 is stacked.

Further, the leg members 131a and 131b, and the leg members 131c and 131d can be expanded and contracted stepwise in the height direction. That is, as indicated by the two-dot chain line in FIG. 3, the height of the top plate portion 110 can be adjusted stepwise.
Further, in the workbench 100 of the present embodiment, the legs 130 do not completely extend vertically in the open state, but are inclined with respect to the vertical direction in order to improve stability. That is, when the workbench 100 is viewed in the left-right direction as shown in FIG. 3, the pair of legs are inclined away from each other as they go from the upper end to the lower end.

The rotating portion 150 serves to rotate the leg portion 130 with respect to the top plate portion 110 . By rotating the leg portion 130 with respect to the top plate portion 110 via the rotating portion 150, the leg portion 130 extends downward and the leg portion 130 overlaps the top plate portion 110. It changes to the folded closed leg posture. Specifically, the rotating portion 150 has four rotating bodies 151a to 151d. Note that the rotating bodies 151b and 151d are not shown in FIG. 3 because they are hidden by the rotating bodies 151a and 151c, respectively. The rotating bodies 151a-151d are arranged between the leg members 131a-131d and the top plate portion 110, respectively.
Here, as shown in FIG. 3, the fulcrum P1 of the rotating bodies 151a and 151b is positioned above the fulcrum P2 of the rotating bodies 151c and 151d, that is, offset to the top plate portion 110 side.

The traveling part 180 plays a role of moving the workbench 100 to an arbitrary position while supporting the top plate part 110 and the leg part 130 . The running portion 180 is connected to the lower side of the leg portion 130 . Specifically, the traveling portion 180 has four casters 181a to 181d. Note that the casters 181b and 181d are not shown in FIG. 3 because they are hidden by the casters 181a and 181c, respectively. Casters 181a-181d are rotatably connected to the lower ends of leg members 131a-131d, respectively. The casters 181a to 181d are casters with stoppers that can fix the rotation of the wheels according to the operation of the operator. When a worker performs a high-place work, he operates the pedals of the casters 181a to 181d of the traveling unit 180 to fix the rotation of the wheels, thereby safely performing the high-place work without moving the workbench 100. be able to.

FIG. 4 is a diagram showing a closed leg state in which the leg portion 130 is folded with respect to the top plate portion 110 via the rotating portion 150. FIG. When the legs 130 are folded, the top plate 110 is folded so as to be in contact with the floor surface. When the leg portion 130 is folded, the top plate portion 110, the leg member 131a, and the leg member 131c overlap in this order from the bottom. Here, since the rotation fulcrum P1 of the leg member 131a is offset from the rotation fulcrum P2 of the leg member 131c so as to be positioned closer to the top plate portion 110, the leg members 131a and 131c It is folded up to a position parallel to the plate portion 110 . Therefore, the thickness of the folded workbench 100 can be made compact.

Next, the bridge 200 will be explained.
The bridge 200 of the present embodiment has a traveling portion 230 and functions not only as a scaffolding for performing high-place work but also as a carriage on which the workbench 100 is loaded.
FIG. 5 is a plan view showing an example of the configuration of the bridge 200. As shown in FIG. FIG. 6 is a front view showing an example of the configuration of the bridge 200. As shown in FIG. FIG. 7 is a bottom view showing an example of the configuration of the bridge 200. FIG.

Bridge 200 has main body portion 210 and running portion 230 .
The main body 210 serves as a scaffolding for workers who work at heights. Further, the body portion 210 plays a role as a loading portion when loading the workbench 100 when the bridge 200 functions as a carriage. As shown in FIG. 5, the main body 210 has a substantially rectangular shape elongated in the front-rear direction when viewed from above. In the present embodiment, the main body 210 has a length of approximately 1500 mm in the front-rear direction (longitudinal direction) and a length of approximately 1000 mm in the left-right direction (lateral direction), for example. In this embodiment, the size of the body portion 210 of the bridge 200 and the size of the top plate portion 110 of the work table 100 are substantially the same. However, the size of the main body portion 210 and the size of the top plate portion 110 are not limited to substantially the same size, and the size of the main body portion 210 may be larger than the size of the top plate portion 110 . Further, the body portion 210 may have approximately the same length in the front-rear direction and in the left-right direction.

The body portion 210 is configured by connecting a plurality of elongated members. Specifically, the main body 210 has a plurality of (for example, four) long longitudinal members 211a to 211d that are long in the front-rear direction and connected side by side. It is fixed using rivets (including blind rivets). Longitudinal members 211a to 211d and short members 212a and 212b are made of, for example, an aluminum alloy and formed by extrusion molding. The long members 211a to 211d, the short members 212a, and the short members 212b are metallic in color such as silver.

The body portion 210 has a plurality of projections 213 as anti-slip surfaces on the work surface. The protrusions 213 are formed over the entire surface of the body portion 210 at intervals. The protrusion 213 protrudes circularly upward and has a hole in the center.
Further, the body portion 210 has a plurality of connecting holes 218 at positions close to the outer peripheral edge. A connecting hole 218 is a hole for connecting with a connecting bar of the workbench 100 . For example, six connecting holes 218 are formed in each of the longitudinal members 211a and 211d, and four connecting holes are formed in each of the short members 212a and 212b. In addition, the connecting hole 218 of this embodiment is configured by arranging a cylindrical member in an opening formed in the main body portion 210 . The cylindrical member is given a different color (for example, red) from the surface of the body portion 210 .

Further, the main body part 210 has a connecting pin 221 at the end on the side connected to the workbench 100 . Specifically, two connecting pins 221 are provided at both ends of the short member 212a and two at both ends of the short member 212b. The connecting pin 221 is attached to a plate-shaped bracket 222 extending rearward from the short member 212a and a plate-shaped bracket 222 extending forward from the short member 212b. The connecting pin 221 protrudes downward from the lower surface of the bracket 222 . The bridge 200 and the work table 100 are connected by inserting the connection pins 221 into the connection holes of the work table 100 from above. Here, the connecting pin 221 and the bracket 222 correspond to an example of the connecting portion.

The running part 230 plays a role of running on the floor surface while supporting the load of the body part 210 and the load when the bridge 200 functions as a carriage. As shown in FIG. 7, the traveling portion 230 has a plurality (four) of casters 231a to 231d arranged at four corners on the lower side of the main body portion 210. As shown in FIG.
The casters 231a to 231d are attached to the lower side of the main body 210 via mounting plates 232, respectively. The casters 231a to 231d can be swiveled around the swivel axis O along the vertical direction. In FIG. 7, the wheels 233, which will be described later, are oriented in the front-back direction. can run.
In this embodiment, the distance between the pivot axis O of the caster 231a and the pivot axis O of the caster 231b and the distance between the pivot axis O of the caster 231c and the pivot axis O of the caster 231d are approximately 780 mm, for example. . Also, the distance between the turning axis O of the caster 231a and the turning axis O of the caster 231c and the distance between the turning axis O of the caster 231b and the turning axis O of the caster 231d are approximately 1330 mm, for example.

The casters 231a to 231d are casters with brakes that can be braked or released according to the operator's operation. Specifically, casters 231a to 231d have wheels 233, fork members 234 as support portions, and brake pedals 235. As shown in FIG. 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 operation portion 236 for stepping on the distal end thereof. When the operator presses the operation unit 236 downward during braking, the outer peripheral surface of the wheel 233 is pressed, and the wheel 233 is braked. By further depressing the operating portion 236 by the operator, the wheels 233 are kept in a braked state.

5 to 7 show the state in which the brake is not applied (the state when the brake is released). As shown in FIGS. 5 to 7, the casters 231a and 231b, which are on the rear side when the bridge 200 is running, have the operation portion 236 of the brake pedal 235 positioned behind the rear end of the short member 212a. exposed.
In other words, when the brake is released and the wheels 233 face forward and backward, the operating portion 236 is positioned away from the outer edge of the main body portion 210 in a plan view. Therefore, the operator can easily depress the operating portion 236 when the brake needs to be applied.
In addition, when the brake is released and the wheels 233 face forward and backward, the operating portion 236 is positioned so as not to overlap the connecting pin 221 and the bracket 222 in 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 by the connecting pin 221 and the bracket 222 .

Next, a case will be described where the bridge 200 functions as a scaffolding for a worker to perform high-place work. First, an operator installs two workbenches 100a and 100b at separate positions. At this time, the workbench 100a and the workbench 100b are separated from each other by about the length of the bridge 200 in the front-rear direction.
Next, the worker bridges the bridge 200 between the workbench 100a and the workbench 100b. Specifically, the connecting pins 221 of the body portion 210 of the bridge 200 are inserted into the connecting holes as the connected portions of the workbench 100a and the workbench 100b, respectively. Therefore, as shown in FIGS. 1 and 2, the bridge 200 is connected to the workbench 100a and the workbench 100b to constitute the workbench system 10. FIG. At this time, the running portion 230 of the bridge 200, that is, the casters 231a to 231d are vertically separated from the floor surface.

In particular, even when the leg members 131a to 131d are extended and contracted so that the heights of the top plate portions 110 of the workbench 100a and the workbench 100b are the lowest, the casters 231a to 231d do not reach the floor surface. vertically away from Therefore, when the bridge 200 is functioning as a scaffolding, it is possible to prevent the casters 231a to 231d from contacting the ground and applying a load to the casters 231a to 231d.
In such a workbench system 10, a wide working area can be secured, so that there is no need to move the workbench 100a, 100b when performing high-place work at different positions. Also, a plurality of workers can work simultaneously. Therefore, working using the workbench system 10 can improve work efficiency.

Next, a case will be described in which the bridge 200 functions as a carriage for a worker to reassemble. First, the operator removes the bridge 200 connected to the workbench 100a and the workbench 100b, and grounds the casters 231a to 231d to the floor.
Next, the operator folds the legs 130 of the workbench 100a and the workbench 100b. Therefore, as shown in FIG. 4, the workbench 100a and the workbench 100b overlap in the order of the top plate portion 110, the leg members 131a, and the leg members 131c from below.

Next, the worker loads the workbench 100 a onto the body portion 210 of the bridge 200 . That is, the surface of the body portion 210 is used as a loading surface for loading cargo. At this time, with the top plate portion 110 of the work table 100a facing downward and the leg portions 130 facing upward, the top plate portion 110 of the work table 100a and the main body portion 210 of the bridge 200 are loaded.
Subsequently, the worker loads the workbench 100b so as to be stacked on the workbench 100a. At this time, similarly to the workbench 100a, the workbench 100b is loaded on the workbench 100a with the top plate portion 110 facing downward and the leg portion 130 facing upward. Since the contact member 138 is provided on the lower work table 100a, the work table 100b can be stably stacked by contacting the contact member 138 when stacking the upper work table 100b. can be done.

FIG. 8 is a diagram showing a state in which the workbench 100a and the workbench 100b are loaded on the bridge 200. As shown in FIG. In order to prevent cargo from collapsing, the operator binds workbench 100a and workbench 100b loaded on main body 210 of bridge 200 to main body 210 with belt 240 as a flexible binding member. The bridge 200 is not limited to loading two workbenches 100a and 100b, and may load three or more workbenches as indicated by the two-dot chain line in FIG. In FIG. 8, by stepping on the operating portion 236 of the caster 231a as indicated by the chain double-dashed line, the bridge 200 can be kept in a braked state without unintentionally moving.
In this way, by making the bridge 200 function as a carrier, the workbench 100 can be easily transported without the need to procure a new carrier even in the case of remodeling.

FIG. 9 is a perspective view of the belt 240 used to bind the worktables 100a and 100b to the main body 210 of the bridge 200 and also used in the worktable system 10. FIG.
As shown in FIG. 9, the belt 240 connects the legs 130 of the workbench 100a and the workbench 100b over which the bridge 200 is laid. The operator winds the belt 240 annularly between the horizontal member 137 of the workbench 100a and the horizontal member 137 of the workbench 100b. At this time, it is preferable that the horizontal members 137 around which the belt 240 is wound have the same height and are positioned as low as possible.
Next, the operator uses the length adjusting section 241 of the belt 240 to adjust the length of the belt 240 to be shorter. Therefore, the work table 100a and the work table 100b are connected while being biased in a direction in which the distance between the leg portion 130 of the work table 100a and the leg portion 130 of the work table 100b is shortened. In this way, by connecting the leg portions 130 of the worktables 100a and 100b over which the bridge 200 is bridged by the belt 240, even if the operator forgets to operate the pedal of one of the casters 181a to 181d, the wheel is fixed. Unintentional movement of the workbenches 100a and 100b can be suppressed even when the work at height is performed in a state where the workbench 100a and 100b are not installed.

In this way, the belt 240 is used to tie the load to the main body 210 when the bridge 200 functions as a carriage, and to connect the legs 130 of the workbenches 100a and 100b when the bridge 200 functions as a scaffold. , the belt 240 can be effectively used.
In this embodiment, the case where the belt 240 is used as the binding member has been described, but any other member may be used as long as it is an elongated member.
Moreover, in the present embodiment, the case where the belt 240 is looped around the horizontal member 137 of the workbench 100a and the horizontal member 137 of the workbench 100b by respectively folding back has been described. However, one end of the belt 240 may simply be connected to the leg portion 130 of the workbench 100a and the other end of the belt 240 may be connected to the leg portion 130 of the workbench 100b without being folded back. Also, the leg members of the workbenches 100a and 100b may be connected by belts 240. FIG.

(Second embodiment)
The workbench system 10 of the first embodiment has been described as a configuration suitable for performing high-place work such as a narrow passageway such as a corridor as a work site. In this embodiment, a configuration suitable for high-place work such as a wide floor as a work site will be described.
FIG. 10 is a diagram showing an example of the configuration of the workbench system 20. As shown in FIG. The workbench system 20 of the present embodiment includes a plurality of (for example, four) workbench 100 (100a to 100d), bridges 200 (200a, 200b) with running units, and bridges 300 (300a to 300i) without running units. there is

The workbenches 100a to 100d have the same configuration as the workbenches 100 of the first embodiment. Also, the bridges 200a and 200b with running portions have the same configuration as the bridge 200 of the first embodiment. In other words, the bridges 200a and 200b with running parts also function as carriages for loading the workbenches 100a to 100d. On the other hand, the non-running bridges 300a-300i do not have a running portion. In other words, the bridges 300a to 300i without running parts merely function as scaffolds, and do not function as carriages for loading the workbenches 100a to 100d.
The bridges with running parts 200a and 200b function as carriages to be recognized by the operator. The color may be different from the color of the body portion 310 . For example, at least one of the long members 211a to 211d and the short members 212a and 212b of the bridges 200a and 200b with running portions is gold, and the outer peripheral portions of the bridges 300a to 300i without running portions are silver. etc.

The workbenches 100a to 100d are installed in the same direction and separated from each other. The bridge 200a with a running portion is arranged to bridge the short side end of the workbench 100a and the short side end of the workbench 100b. In addition, the bridge 200b with the running portion is disposed so as to bridge the short side end of the workbench 100c and the short side end of the workbench 100d.
The bridges without running parts 300a to 300c are arranged to span the longitudinal end of the work table 100a and the longitudinal end of the work table 100c. Further, the bridges without running portion 300d to 300f are arranged to span the longitudinal end of the bridge with running portion 200a and the longitudinal end of the bridge with running portion 200b. In addition, the bridges 300g to 300i without running parts are arranged to span the longitudinal end of the work table 100b and the longitudinal end of the work table 100d.

The workbench system 20 of the present embodiment is arranged with workbench 100a to 100d, bridges with running parts 200a and 200b, and bridges without running parts 300a to 300d without gaps, so that a wide space such as a floor can be used as a work site. This configuration is suitable for Here, the workbench 100a corresponds to an example of a first workbench, the workbench 100b corresponds to an example of a second workbench, and the workbench 100c corresponds to an example of a third workbench. Also, the bridge with running portion 200a corresponds to an example of a first workbench bridge, and the bridge without running portion 300a corresponds to an example of a second workbench bridge.

The non-running bridges 300a to 300i have the same configuration. The running portionless bridge 300 has a substantially plate-like body portion 310 . The body portion 310 is made of, for example, an aluminum alloy and is formed by extrusion molding. Further, the main body portion 310 is entirely metallic in color such as silver. The body portion 310 has a length of, for example, approximately 500 mm in the front-rear direction (transverse direction), and a length of approximately 1500 mm in the lateral direction (longitudinal direction). Here, assuming that the top plate portion 110 of the work table 100 and the main body portion 210 of the bridge 200 with the running portion have the same size as in the first embodiment, the top plate portion 110 of the work table 100 is on the longitudinal side. At the longitudinal end of the end and run bridge 200, three runless bridges 300 can be connected in parallel.

Next, a case will be described where the bridges 200a and 200b function as carriages for the operator to reassemble. First, the operator removes the bridges with running portions 200a and 200b and the bridges without running portions 300a to 300i, and grounds the running portions 230 of the bridges with running portions 200a and 200b to the floor.
Next, the operator folds the leg portions 130 of the worktables 100a to 100d and loads them onto the bridge 200a with a running portion. Also, the operator loads the bridges without running section 300a to 300i on the bridge with running section 200b. At this time, the bridges 300a to 300i without running portions are substantially plate-shaped, and there are no members protruding upward and downward from the main body portion 310, so that the height when loaded can be reduced.

When the bridges without running portions 300a to 300i are loaded on the bridge with running portions 200b, the longitudinal direction of the bridges without running portions 300a to 300i is aligned with the longitudinal direction of the bridge with running portions 200b. . At this time, since the lengths in the transverse direction of the bridges without running portions 300a to 300i are shorter than the lengths in the transverse direction of the bridges with running portions 200b, the bridges without running portions 300a to 300i are the same as the bridges with running portions 200b. can be loaded without protruding from both sides of the body portion 210. In addition, the length in the lateral direction of the bridges 300a to 300i without running portions is shorter than the distance between the pivot axis O of the caster 231a and the pivot axis O of the caster 231b. Therefore, since the bridges without running parts 300a to 300i can be loaded between the adjacent turning shafts O, the vibrations of the bridges without running parts 300a to 300i from the casters 231a to 231d can be suppressed.

By making the bridges 200a and 200b function as carriages in this way, there is no need to procure new carriages even when remodeling is carried out, and workbenches 100a to 100d and no running unit can be easily installed. Bridges 300a-300i can be transported.
Moreover, since the bridges without running parts 300a to 300i are not provided with casters and are substantially plate-shaped, the bridges without running parts 300a to 300i can be stacked without being bulky.

Although the workbench system 20 has two bridges 200a and 200b with running parts, one of the bridges 200a and 200b may have no running parts. That is, in the bridges 200a and 200b having the same size of the body portion 210, the bridges with the running portion and without the running portion may be mixed. In this case, a part of the body portion 210 of the bridge with running portion 200a may have a different color from the color of the body portion 210 of the bridge without running portion 200b. For example, at least one of the long members 211a to 211d, the short members 212a, and the short members 212b of the bridge 200a with the running portion is gold-colored, and the long members 211a to 211d, the short members 212a, and the long members 211a to 211d of the bridge 200 without the running portion are The color of the short member 212b may be silver or the like.

Also, the case where the bridges 300a to 300i without the traveling part in the workbench system 20 have a length of approximately 1500 mm in the left-right direction (longitudinal direction) of the main body 310 has been described, but the length is approximately 500 mm, approximately 1000 mm, approximately 2000 mm , approximately 2500 mm. Moreover, although the front-rear direction (transverse direction) of the main body has been described as having a length of, for example, approximately 500 mm, it may have a length of approximately 750 mm, approximately 1500 mm, or the like.
Further, in order to connect the legs 130 with the belt 240 in the present embodiment, for example, the leg members of the worktables 100a and 100c or the leg members of the worktables 100b and 100d may be connected.

(Third embodiment)
In this embodiment, the body portion 210 of the bridge 200 has an anti-floating member 250 as an anti-floating mechanism. The floating prevention member 250 prevents the bridge 200 from floating from the workbench 100 when the bridge 200 is connected to the workbench 100 .
FIG. 11 is a bottom view showing an example of the configuration of the bridge 200 according to this embodiment. FIG. 12 is a cross-sectional view of a portion of the bridge 200 where the anti-floating member 250 is located and viewed from the left and right. Note that the description of the same configuration as in the first embodiment will be omitted as appropriate.

The bridge 200 is provided with a plurality of (for example, two) anti-uplift members 250 spaced apart in the left-right direction via brackets 260 at the end on the side connected to the workbench 100 . In addition, each of the floating prevention members 250 is positioned on the right side (center side of the main body 210 in the left-right direction) of the line connecting the turning axis O of the caster 231a and the turning axis O of the caster 231c, and and the pivot axis O of the caster 231d to the left (center side of the main body 210 in the left-right direction). In addition, the anti-floating member 250 is positioned closer to the center of the body portion 210 than the line connecting the connecting pins 221 adjacent in the lateral direction.
As shown in FIG. 12 , the anti-uplift member 250 has a guide shaft 251 , a contact member 252 and a spring member 253 .
The guide shaft 251 protrudes downward from the lower surface of the bracket 260 and guides the vertical movement of the contact member 252 .
The contact member 252 has an upper piece 252a and a lower piece 252b, and is formed in a substantially U shape. The upper piece 252a has a substantially plate shape, and the guide shaft 251 is inserted therethrough. The lower piece 252b has a substantially plate-like shape and functions as a contact portion capable of contacting the lower surface of the main body portion 210 of the bridge 200 and the lower surface of the top plate portion 110 of the workbench 100. As shown in FIG.
The spring member 253 is arranged between the lower end of the guide shaft 251 and the upper piece 252a of the contact member 252, and biases the contact member 252 upward, that is, toward the bracket 260 side.

12A and 12B show the state before and after the contact member 252 is rotated about the guide shaft 251 by 90 degrees. Here, the width of the lower piece 252b of the contact member 252 is W (see FIG. 12A), and the length orthogonal to the width W is S (see FIG. 12B). The width W is shorter than the distance L1 from the outer edge of the lower surface of the body portion 210 of the bridge 200 to the outer edge of the lower surface of the top plate portion 110, and the length S is longer than the distance L1.
On the other hand, the top plate portion 110 of the workbench 100 has a plate-like side portion 111 at its outer peripheral end, and a plate-like lower portion 112 is connected to the side portion 111 to form a substantially L shape. In the present embodiment, a notch is provided in the longitudinal direction of the side portion 111 and the lower portion 112 and at a position close to the anti-floating member 250 when the bridge 200 is connected. It has a portion (recess) 113 . The notch 113 is concave, and the lower piece 252b of the contact member 252 is engaged. Note that the cutout portion 113 may be provided in either the side portion 111 or the lower portion 112 .

Next, the operation of preventing the bridge 200 from rising by the contact member 252 will be described.
First, from the state of FIG. 12A, the operator connects the bridge 200 to the work table 100 by inserting the connection pins 221 into the connection holes 118 of the work table 100 from above.
Next, as shown in FIG. 12B, the operator pulls the contact member 252 against the biasing force of the spring member 253 and rotates it about the guide shaft 251 by 90 degrees. Release the tension at 252. Therefore, the lower piece 252 b of the contact member 252 is in contact with the lower side of the top plate portion 110 and the lower side of the bridge 200 . Even if a force is applied to the bridge 200 to lift it upward in such a state, the lower piece 252b is in contact with the lower side of the top plate portion 110, thereby preventing the bridge 200 from lifting. can be done.

Further, when the lower piece 252b of the present embodiment comes into contact with the lower side of the top plate portion 110, it enters into the notch portion 113 of the top plate portion 110 from below and engages therewith. Therefore, for example, even if the bridge 200 vibrates due to work at height and the vibration is transmitted to the contact member 252, the contact member 252 does not rotate due to the vibration and leave the notch 113. It is possible to prevent the contact between the member 252 and the top plate portion 110 from being released.
In addition, although the case where there are two anti-lifting members 250 at each end of the main body 210 on the side connected to the workbench 100 has been described, the present invention is not limited to this case, and there may be one or three or more.

Here, the connecting pin 521 corresponds to an example of a connecting portion.
The abutting portions 523 are provided substantially in the center of the longitudinal ends. The contact portion 523 has a plate-like shape extending substantially horizontally toward the right side and the left side from substantially the center of the longitudinal end portion of the main body portion 510 . By spanning the bridge 500 without a running part over the work table 400 , the contact part 523 contacts the upper surface of the top plate part 110 of the work table 400 .

The floating prevention mechanism 530 is engaged with the top plate portion 110 of the workbench 400 when the bridge without running portion 500 is bridged over the workbench 400 to prevent the bridge without running portion 500 from rising from the top plate portion 110. - 特許庁It is a mechanism for The anti-floating mechanisms 530 are provided on the lower side of the body portion 510 and close to the ends of the body portion 510 on the short side. In other words, two anti-floating mechanisms 530 are provided for one bridge 500 without running section, and each of them has substantially the same configuration.
FIG. 16 is a view of the bridge without running portion 500 as seen from the front side, and is a view showing an example of the configuration of the lifting prevention mechanism 530. As shown in FIG. FIG. 16(a) shows the state before the bridge 500 without running parts is laid over the workbench 400, and FIG. 16(b) shows the state after the bridge 500 without running parts is laid over the workbench 400. .

The anti-uplift mechanism 530 is composed of a pair of units each having a stopper member 531, a biasing member 534, and a guide member 535, which are substantially symmetrical with respect to the center line C in the left-right direction. Here, one unit will be described, but the other unit has the same configuration.
The stopper member 531 is a member that engages with the top plate portion 110 when positioned below the top plate portion 110 of the adjacent workbench 400 and is disengaged when the stopper member 531 moves away from the bottom portion of the top plate portion 110 . is. The stopper member 531 is made of iron, for example, and has a substantially bar shape. The stopper member 531 is metallic in color such as silver, for example. The stopper member 531 is arranged along the left-right direction on the lower side of the main body portion 510 .

The stopper member 531 has an engaging portion 532 and a lever portion 533 . The engaging portion 532 is positioned at the tip of the stopper member 531 . The lever portion 533 is located on the opposite side of the engaging portion 532 and close to substantially the center of the body portion 510 in the left-right direction. The lever portion 533 extends in a direction substantially orthogonal to the left-right direction. The stopper member 531 is constantly urged in the direction in which the engaging portion 532 protrudes from the end portion of the main body portion 510 by an urging member 534 arranged between the engaging portion 532 and the lever portion 533 . The biasing member 534 is, for example, a coil spring and is arranged between the intermediate position of the stopper member 531 and the guide member 535 . The lever portion 533 is a portion that is operated by the operator to slide the stopper member 531 in the left-right direction against the biasing force of the biasing member 534 so that the engaging portion 532 does not protrude from the main body portion 510 . . Here, the lever portion 533 is covered by covering the outer circumference with an operation lever made of synthetic resin, for example. The operating lever is colored differently from the stopper member 531 .

It should be noted that only one floating prevention mechanism 530 may be provided for one bridge 500 without a running portion. Also, the anti-uplift mechanism 530 may be configured as a single unit instead of being configured as a pair of units. Further, the floating prevention mechanism 530 may be provided inside the body portion 510 so that the lever portion 533 is exposed from the body portion 510 and the engaging portion 532 projects or retracts from the body portion 510 . The stopper member 531 is rotatable such that the longitudinal direction of the lever portion 533 is parallel to the upper surface of the body portion 510 .

Next, the configuration of the bridge 600 with running portion will be described with reference to FIG. 17 . 17A and 17B are a plan view, a front view, and a side view showing an example of the configuration of the bridge 600 with running portions. The same reference numerals are given to the same configurations as the bridge 200 of the first embodiment, and the description thereof is omitted.

Bridge 600 with running portion has body portion 610 and running portion 230 .
The main body portion 610 has a substantially rectangular shape elongated in the front-rear direction in a plan view. In the present embodiment, the length in the front-rear direction (longitudinal direction) of the body portion 610 is approximately 1500 mm, and the length in the left-right direction (lateral direction) is approximately 1000 mm, for example. The size of the top plate portion 110 of the workbench 400, the size of the body portion 510 of the bridge without running portion 500, and the size of the body portion 610 of the bridge with running portion 600 are substantially the same. However, the size of main body portion 610 is not limited to being approximately the same as that of top plate portion 110 and main body portion 210 . Further, the body portion 610 may have approximately the same length in the front-rear direction and in the left-right direction.

The main body portion 610 has a connecting pin 621 and a contact portion 623 at the end on the longitudinal side, which is the side connected to the workbench 400 .
The connecting pins 621 are provided at both ends of the longitudinal side. The connecting pin 621 is attached to a plate-shaped bracket 622 extending from the longitudinal end of the main body 610 toward the right and left sides. The connecting pin 621 protrudes downward from the lower surface of the bracket 622 . By inserting the connecting pins 621 into the connecting holes 118 of the workbench 400 from above, they are connected to the workbench 400 . Here, the connecting pin 621 corresponds to an example of a connecting portion.
The abutting portions 623 are provided substantially in the center of the longitudinal ends. The contact portion 623 has a plate-like shape extending substantially horizontally toward the right side and the left side from substantially the center of the longitudinal end portion of the main body portion 610 . By spanning the bridge 600 with the running part over the work table 400 , the contact part 623 contacts the upper surface of the top plate part 110 of the work table 400 .
In addition, the bridge 600 with a traveling part may have a lifting prevention mechanism 530 . In this case, it is preferable that the floating prevention mechanism 530 is arranged inside the main body portion 610 so as not to interfere with the traveling portion 230 .

Next, a method for assembling the workbench system 30 described above will be described. Contents similar to those of the first embodiment will be omitted as appropriate.
First, the worker arranges the worktables 400a to 400c and the worktables 400d to 400f in series along the front-rear direction. At this time, the worker arranges the worktables 400a to 400c and the worktables 400d to 400f with a predetermined spacing in the horizontal direction. Also, the worker connects the connecting bar 114 to the connecting hole 118 of the adjacent workbench 400 .

Next, the operator bridges the bridge without running portion 500 and the bridge with running portion 600 between the worktables 400a to 400c and the worktables 400d to 400f, which are arranged at regular intervals in the horizontal direction. Specifically, the operator bridges the bridge without running portion 500a between the work benches 400a and 400d, and bridges the bridge without running portion 500b between the work benches 400c and 400f. Also, the operator bridges the bridge 600 with the traveling part between the workbench 400b and the workbench 400e.

Here, a case where the bridge 500 without a traveling part is bridged between remote workbenches 400 will be described with reference to FIGS. 16(a) and 16(b).
When the operator lays the bridge 500 without running parts on the workbench 400, the operator operates the lever part 533 against the biasing force of the biasing member 534 to slide the stopper member 531 in the left-right direction. Therefore, as shown in FIG. 16A, the engaging portion 532 of the stopper member 531 slides in a direction in which it does not protrude from the body portion 510, that is, in a direction in which it is retracted toward the body portion 510 side. At this time, since the two lever portions 533 are positioned adjacent to each other at the center of the main body portion 510 in the left-right direction, the operator can grasp the two lever portions 533 with one hand, thereby forming a pair of stopper members. 531 can be slid at once.

Next, the operator bridges the bridge 500 without running parts over the workbench 400 while the engaging part 532 of the stopper member 531 is retracted toward the main body part 510 . At this time, the connecting pin 521 is inserted into the connecting hole 118 of the work table 400 and the contact portion 523 contacts the top surface of the top plate portion 110 of the work table 400 . Also, after the operator places the bridge 500 over the workbench 400 , the operator releases the lever portion 533 . Therefore, as shown in FIG. 16B, the stopper member 531 is urged by the urging member 534 to slide in the direction in which the engaging portion 532 protrudes from the body portion 510 . By projecting the engaging portion 532 , the engaging portion 532 is positioned below the top plate portion 110 of the adjacent workbench 400 and engages with the top plate portion 110 . Since two lifting prevention mechanisms 530 are provided for one bridge 500, the operator engages the engaging portion 532 of the other lifting prevention mechanism 530 with the top plate portion 110 in the same manner. match.

Next, a description will be given of a case where the workbench 400b and the workbench 400e, which are separated from the bridge 600 with the traveling part, are bridged. If the bridge with running portion 600 has the floating prevention mechanism 530 , the bridge without running portion 500 can be bridged between the workbenches 400 in the same manner. When the bridge with running portion 600 does not have the lifting prevention mechanism 530 , the operator bridges the bridge with running portion 600 over the workbench 400 so that the connecting pin 621 is connected to the connecting hole 118 of the workbench 400 . It is inserted, and the contact portion 623 contacts the upper surface of the top plate portion 110 of the workbench 400 .

Note that the position where the bridge with running portion 600 is arranged is not limited to being between the bridge without running portion 500a and the bridge without running portion 500b, but on the frontmost side in the front-rear direction, that is, between the work benches 100c and 100f. It may be arranged on the rearmost side, that is, between the workbench 100a and the workbench 100d. That is, the bridge with running portion 600 can be interchanged with the bridge without running portion 500a or the bridge without running portion 500b.
Further, when the bridge with running portion 600 is arranged between the bridge without running portion 500a and the bridge without running portion 500b, the lifting prevention mechanism of the second embodiment may be provided. In this case, the bridge with running portion 600 can be prevented from floating with respect to the bridge without running portion 500a and the bridge without running portion 500b.

Next, as shown in FIG. 13, the operator transitions the auxiliary grounding portion 190 of the workbench 400, specifically the auxiliary leg members 191a to 191d, from the second state to the first state. In consideration of workability, the operator shifts at least the outer auxiliary leg members 191a to 191d of the auxiliary leg members 191a to 191d of the worktables 400a to 400f from the second state to the first state. transition.

In the workbench systems 10, 20, 30 described above, auxiliary handrails may be attached to the workbench 100, 400, the bridges 200, 300, the bridge without running portion 500, and the bridge with running portion 600, if necessary. For example, an auxiliary handrail is attached to the outer periphery of the entire work scaffold composed of the worktables 100 and 400, the bridges 200 and 300, the bridge without a running portion 500, and the bridge with a running portion 600, and the work area is defined by the auxiliary handrail. Surrounding the workers allows them to work safely.

In the workbench systems 10, 20, and 30 described above, an example of a narrow passageway and a wide floor was explained as a work site. By increasing or decreasing the number of scaffolds or changing their positions, it is possible to form a work scaffold according to the shape of the work site. For example, if there are pillars at the work site, remove a part of the bridges 200 and 300, the bridge without running part 500, and the bridge with running part 600, and insert the pillars into the removed positions to prevent interference with the pillars. be able to.

In the worktables 100 and 400 described above, the case where the leg members 131a to 131d are extendable has been described, but the leg members 131a to 131d may not be extendable.
Although the above-described workbenches 100 and 400 are folded so that the top plate portion 110, the leg member 131a, and the leg member 131c overlap in this order in the leg-closed posture, the present invention is not limited to this case. When the length of 131d is short or when the top plate portion 110 is large, the leg members 131a and 131c do not overlap each other, and the top plate portion 131a and the leg member 131c are adjacent to each other in the front-rear direction. It may directly overlap 110 .

In the bridge 200 and the bridge 600 with a running section described above, the case where the running section 230 has four casters 231a to 231d has been described, but the present invention is not limited to this case and may have five or more casters.
