Description

[Technical Field]

[0001] The present invention relates to a workbench. [Background technology]

[0002] Conventionally, various types of work platforms (scaffolding) have been used for interior construction work on buildings, etc. A work platform has, for example, a work floor, a support part that supports the work floor, and a plurality of (for example, four) handrail frames that are detachably attached to the work floor. In such a work platform, for example, installation holes for inserting the handrail posts of the handrail frame are provided at the four corners of the work floor, and the handrail frame is attached to the work floor by inserting the handrail posts into the installation holes from above.

[0003] In the case of a work platform like the one described above, if the work floor is low, the worker can easily insert the handrail post of the handrail frame into the installation hole, but if the work floor is high, it becomes difficult to insert the handrail post into the installation hole. Therefore, a structure has been proposed in the past that allows the handrail post to be attached to the work floor from the side.

[0004] For example, in the work scaffolding device disclosed in Patent Document 1, an upper jaw member and a lower jaw member are provided on each support post of a handrail frame (see Figures 10 to 14 of Patent Document 1). The upper jaw member and the lower jaw member are provided separately above and below, and the upper jaw member is provided with a vertical rod that can move up and down toward the lower jaw member. Locking holes for inserting the vertical rod are formed on the upper and lower surfaces of the edge of the work floor.

[0005] When attaching the handrail frame to the work platform (top plate) of the working scaffolding device of Patent Document 1, the edge of the work platform is fitted into the space between the upper jaw member and the lower jaw member, and the vertical rod is inserted into the edge of the work platform so as to penetrate the edge. This connects the upper jaw member and the lower jaw member to the edge of the work platform via the vertical rod. In this way, each support post of the handrail frame can be attached to the work platform from the side of the work platform. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2024-4748 Summary of the Invention [Problem to be solved by the invention]

[0007] In the work scaffolding device disclosed in Patent Document 1, as described above, it is necessary to connect the support posts of the handrail frame to the work floor by inserting the vertical rod into the edge of the work floor so as to penetrate the edge of the work floor in the vertical direction. In this configuration, when a worker pushes the handrail frame toward the outside of the work floor, a large load acts from the handrail frame (support post) to the edge of the work floor via the vertical rod.

[0008] Therefore, an object of the present invention is to provide a workbench that prevents a large load from acting on the edge of the work floor from the handrail frame. [Means for solving the problem]

[0016] Hereinafter, a workbench according to an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a front view showing a workbench according to an embodiment of the present invention, and Fig. 2 is a left side view showing the workbench of Fig. 1.

[0017] (Outline of workbench configuration) As shown in Figures 1 and 2, the workbench 10 of this embodiment comprises a work floor 12, a support portion 14 that supports the work floor 12, a handrail 16 that surrounds the periphery of the work floor 12, and a plurality of receiving portions 18 that extend downward from the work floor 12.

[0018] Although not shown to avoid cluttering the drawings, a ladder is used when a worker ascends or descends the working platform 12. As the configuration of the ladder can be any of various known configurations, a detailed description of the ladder will be omitted. Also, although the details will be described later, the handrail 16 is provided so as to be removable from the working platform 12. The handrail 16 is attached to the working platform 12 when the worker performs work.

[0019] (Working floor configuration) Fig. 3 is a plan view showing the work floor 12. In Fig. 3, floor materials 20b and 22b (see Figs. 1 and 2), which will be described later, are omitted from the illustration in order to avoid cluttering the drawing.

[0020] As shown in Fig. 3, the working floor 12 has a rectangular shape when viewed from above. As shown in Figs. 1 to 3, in this embodiment, the working floor 12 has a first floor section 20 and a second floor section 22 that are arranged side by side in the long side direction of the working floor 12. In the following, when simply referring to the long side direction, it means the long side direction of the working floor 12. Furthermore, when simply referring to the short side direction, it means the short side direction of the working floor 12.

[0021] In the present invention, the rectangular work floor is not limited to a work floor having a perfect rectangular shape as shown in Fig. 3, but includes a work floor configured to form a substantially rectangular shape overall. When the work floor is not a perfect rectangle, the long side direction means the longitudinal direction of the work floor, and the short side direction means the lateral direction of the work floor. In this embodiment, the four corners of the work floor 12 are bent at right angles when viewed from above, but the corners may also be chamfered when viewed from above, for example.

[0022] As shown in Fig. 3, the first floor section 20 has a rectangular frame material 20a when viewed from above. As shown in Figs. 1 and 2, a floor material 20b is fixed onto the frame material 20a. Note that various known floor materials can be used as the floor material 20b. For example, a mesh floor material or a plank floor material may be used. Note that if a plank floor material is used, it is preferable that it be provided with an anti-slip surface.

[0023] As shown in FIG. 3, two holes 20c are formed at each of the four corners of the frame material 20a. In this embodiment, the frame material 20a includes four cylindrical bodies 21a to 21d fixed to each other to form a rectangular shape. The cylindrical bodies 21a and 21b are provided so as to extend in the long-side direction, and the cylindrical bodies 21c and 21d are provided so as to extend in the short-side direction. In this embodiment, square pipes made of metal such as steel are used as the cylindrical bodies 21a to 21d. The holes 20c are formed on the upper surface side of the frame material 20a (the cylindrical bodies 21a to 21d). In this embodiment, the holes 20c are formed at both ends of each of the cylindrical bodies 21a to 21d. The floor material 20b (see FIGS. 1 and 2) is supported by the frame material 20a so as not to cover the holes 20c (so that the holes 20c are exposed).

[0024] In this embodiment, the first floor portion 20 further includes a plurality of reinforcing members 20d. The reinforcing members 20d are provided so as to extend inside the frame member 20a in the long side direction. In this embodiment, a square metal pipe is used as the reinforcing member 20d. The reinforcing member 20d is provided so as to connect the cylindrical member 21c and the cylindrical member 21d. In this embodiment, the floor member 20b is also supported by the plurality of reinforcing members 20d.

[0025] The second floor section 22 has a similar configuration to the first floor section 20, and includes a frame member 22a that is rectangular when viewed from above, and a floor member 22b (see FIGS. 1 and 2) fixed onto the frame member 22a. Similar to the frame member 20a, two holes 22c are formed in each of the four corners of the frame member 22a. Similar to the frame member 20a, the frame member 22a includes four cylindrical members 23a to 23d that are fixed to each other to form a rectangular shape. Furthermore, a plurality of reinforcing members 22d are provided inside the frame member 22a. In this embodiment, the holes 20c and 22c correspond to the first holes.

[0026] (Configuration of the support part) As shown in FIGS. 1 and 2, the support portion 14 supports the work floor 12 from below. Although detailed description is omitted, the support portion 14 is configured to be extendable and retractable in the vertical direction. That is, the workbench 10 according to this embodiment is configured to adjust the height of the work floor 12. In this embodiment, the support portion 14 is supported by a plurality of casters 24 (four in this embodiment). Note that the support portion 14 only needs to be configured to support the work floor 12, and the configuration of the support portion of various known workbenches can be used, so detailed description is omitted. For example, the configuration of the support portion 14 can be the configuration disclosed in Japanese Patent Laid-Open No. 2022-41860. In FIGS. 1 and 2, the support portion 14 is shown in a simplified form.

[0027] (Handrail configuration) 1 and 2, the handrail 16 includes a plurality (six in this embodiment) of handrail frames 30. In this embodiment, one handrail frame 30 is provided on each of a pair of short sides of the work floor 12, and two handrail frames 30 are provided on each of a pair of long sides of the work floor 12.

[0028] Figure 4 is a diagram showing the handrail frame 30. In Figure 4, (a) is a side view of the handrail frame 30, (b) is a front view of the handrail frame 30, (c) is an enlarged side view showing the lower end of the handrail frame 30, and (d) is an enlarged cross-sectional view showing the DD portion of (b). As will be described in detail later, in this embodiment, the handrail frame 30 is attached to the working floor 12 so that the surface shown in Figure 4(b) faces the center of the working floor 12. In the following description of the handrail frame 30, the up-down direction refers to the up-down direction based on the state in which the handrail frame 30 is attached to the working floor 12.

[0029] As shown in Figure 4, the handrail frame 30 has a pair of handrail posts 32, an upper handrail member 34, a middle railing member 36, and a baseboard 38. In this embodiment, each handrail post 32 has a cylindrical shape. The upper handrail member 34 is provided to connect the upper ends of the pair of handrail posts 32. The middle railing member 36 is provided below the upper handrail member 34 to connect the pair of handrail posts 32. The baseboard 38 is provided to connect the lower parts of the pair of handrail posts 32. Note that the handrail posts 32, upper handrail member 34, middle railing member 36, and baseboard 38 can be configured using various known handrail frame configurations, so detailed description will be omitted.

[0030] A mounting portion 40, a mounting pin 42, and abutment portion 44 are provided at the bottom of each handrail post 32. The mounting portion 40 is formed in a plate shape and is provided so as to protrude from the handrail post 32 in a direction perpendicular to the axial direction of the handrail post 32. The mounting pin 42 is supported by the mounting portion 40 so as to protrude downward from the mounting portion 40. In this embodiment, the mounting pin 42 corresponds to the first connecting member.

[0031] The abutment portion 44 is provided below the installation portion 40 so as to protrude from the handrail post 32 in a direction perpendicular to the axial direction of the handrail post 32. The installation portion 40 and the abutment portion 44 are provided so as to protrude from the handrail post 32 toward the inside of the work floor 12 when the handrail frame 30 is attached to the work floor 12.

[0032] In this embodiment, the abutment portion 44 has a cylindrical shape. A pair of holes 44a are formed in the abutment portion 44. When the direction in which the abutment portion 44 is provided relative to the handrail post 32 when viewed from above is defined as the protruding direction, the pair of holes 44a are formed to open in a direction perpendicular to the protruding direction. In this embodiment, the pair of holes 44a are formed to open in the long side direction or short side direction when the handrail frame 30 is attached to the work floor 12. In this embodiment, the holes 44a correspond to the second holes.

[0033] (Configuration of receiving part) As shown in FIG. 3, in this embodiment, a pair of receiving portions 18 is provided at each of the four corners (four corner portions) of the first floor portion 20 (frame material 20a) and the four corners (four corner portions) of the second floor portion 22 (frame material 22a). In this embodiment, a plurality of receiving portions 18 is provided in the first floor portion 20 (frame material 20a) so as to correspond to each of the plurality of holes 20c. Similarly, a plurality of receiving portions 18 is provided in the second floor portion 22 (frame material 22a) so as to correspond to each of the plurality of holes 22c. In this embodiment, each receiving portion 18 is provided below the hole 20c or the hole 22c. Below, the receiving portions 18 provided in the first floor portion 20 (frame material 20a) will be described, but the receiving portions 18 provided in the second floor portion 22 (frame material 22a) have a similar configuration.

[0034] Figures 5 and 6 are diagrams for explaining the configuration of the receiving portion 18. Figures 5(a) and 6 are diagrams showing the circled part in Figure 3 as seen from outside the work floor 12 in the long side direction, Figure 5(b) is a diagram showing the circled part in Figure 3 as seen from outside the work floor 12 in the short side direction, and Figure 5(c) is a cross-sectional view showing part CC in Figure 5(b).

[0035] 3 and 5, the receiving portions 18 have a generally U-shape when viewed from above. The receiving portions 18 are formed of a metal such as steel. Each receiving portion 18 is fixed to the frame material 20a at a corner of the frame material 20a so as to extend downward from the frame material 20a. In this embodiment, of the pair of receiving portions 18 provided at the corners of the frame material 20a when viewed from above, one receiving portion 18 is provided so as to open toward the outside of the work floor 12 in the long side direction, and the other receiving portion 18 is provided so as to open toward the outside of the work floor 12 in the short side direction.

[0036] In this embodiment, the receiving portion 18 includes a back plate portion 18a provided so as to extend in the vertical direction inside the frame material 20a, and a pair of side plate portions 18b provided so as to extend from both edges in the width direction of the back plate portion 18a toward the outside of the frame material 20a. In this embodiment, the pair of side plate portions 18b are fixed to the frame material 20a.

[0037] As shown in FIG. 5, a hole 46a is formed in the upper part of each side plate portion 18b. A hole 46b is formed in the lower part of one of the pair of side plate portions 18b. A hook-shaped connecting member 48 is attached to each receiving portion 18. In this embodiment, the connecting member 48 includes a cylindrical guide portion 48a inserted into the pair of holes 46a in the pair of side plate portions 18b, a cylindrical connecting portion 48b inserted into the hole 46b in the one side plate portion 18b below the guide portion 48a, and a cylindrical connecting portion 48c extending in the vertical direction on the outside of the receiving portion 18 to connect the guide portion 48a and the connecting portion 48b. The connecting portion 48b is shorter than the guide portion 48a. In this embodiment, the connecting member 48 corresponds to the second connecting member.

[0038] Between the pair of side plate portions 18b, the guide portion 48a is provided with a locking portion 48d that protrudes radially from the guide portion 48a. A biasing member 50 is provided on the guide portion 48a so as to be sandwiched between one of the side plate portions 18b and the locking portion 48d. In this embodiment, the biasing member 50 is a coil spring. In this embodiment, the biasing member 50 presses the locking portion 48d toward the other side plate portion 18b. This fixes the position of the connecting member 48 relative to the receiving portion 18.

[0039] 6, in this embodiment, for example, an operator can detach the connecting portion 48b from the receiving portion 18 (side plate portion 18b) by pulling the connecting member 48. When the operator releases the connecting member 48, the force applied to the locking portion 48d by the biasing member 50 returns the connecting member 48 to its original position (the position shown in FIG. 5(a)).

[0040] 5, a plate-shaped reinforcing member 52 made of a metal such as steel is provided at the lower end of each receiving portion 18. In addition, a plate-shaped reinforcing member 54 made of a metal such as steel is provided to connect the pair of receiving portions 18. In this embodiment, the reinforcing members 52 and 54 can improve the rigidity of the pair of receiving portions 18.

[0041] (How to install the handrail frame) Next, we will explain how to attach the handrail frame 30 to the work floor 12. In the following, we will explain how to attach the handrail frame 30 to the cylindrical body 21c of the first floor section 20 (frame material 20a), but the handrail frame 30 can also be attached to other parts of the frame materials 20a and 22a using a similar method.

[0042] 7 to 9 are diagrams illustrating a method for attaching the handrail frame 30 to the work floor 12 (cylinder 21c). In FIG. 7, (a) is a view of one end of the workbench 10 in the long-side direction as viewed from the short-side direction, (b) is a view of one end of the frame material 20a in the short-side direction as viewed from the long-side direction, and (c) is a view of one end of the frame material 20a in the long-side direction as viewed from the short-side direction. In FIG. 8, (a) is a view of one end of the workbench 10 in the long-side direction as viewed from the short-side direction, and (b) is a view of one end of the frame material 20a in the long-side direction as viewed from the short-side direction. In FIG. 9, (a) is a view of one end of the frame material 20a in the short-side direction as viewed from the long-side direction, and (b) is an end view showing the BB cut portion of (a). 7 to 9, the floor material 20b (see FIG. 1) and the receiving portion 18 fixed to the cylindrical body 21a are not shown.

[0043] As shown in Figures 7(a) and 7(c), when attaching the handrail frame 30 to the cylindrical body 21c of the work floor 12, the pair of installation pins 42 of the handrail frame 30 are inserted into a pair of holes 20c (see Figures 3 and 7(c)) formed in the cylindrical body 21c while tilting the handrail frame 30. In this state, as shown in Figure 7(b), by pulling the connecting members 48 below each hole 20c (see Figure 3) of the cylindrical body 21c, the connecting parts 48b are detached from the receiving parts 18 below each hole 20c.

[0044] Next, as shown in Fig. 8, the pair of installation sections 40 are supported on the upper surface of the cylindrical body 21c so that the pair of handrail posts 32 of the handrail frame 30 are parallel in the up-down direction, and the pair of abutting sections 44 are fitted into the pair of receiving sections 18. After that, as shown in Fig. 9, the connecting member 48 is returned to its original position, thereby inserting the connecting section 48b into the hole 44a of the abutting section 44. As a result, the handrail post 32 and the cylindrical body 21c are connected via the installation sections 40 and installation pins 42, as shown in Fig. 8, and the handrail post 32 and the receiving section 18 are connected via the abutting sections 44 and connecting member 48, as shown in Fig. 9. In this way, the handrail frame 30 is attached to the first floor section 20 (frame material 20a).

[0045] (Effects of this embodiment) 8, in the workbench 10 according to this embodiment, when the upper part of the handrail frame 30 is pushed toward the outside of the work floor 12, the lower end of the handrail post 32 (the part below the installation part 40) moves toward the inside of the work floor 12. At this time, the abutment part 44 fixed to the lower end of the handrail post 32 comes into contact with the receiving part 18. Specifically, the abutment part 44 comes into contact with the back plate part 18a of the receiving part 18. As a result, a load is applied from the abutment part 44 to the receiving part 18 in the direction toward the inside of the work floor 12.

[0046] In this way, in this embodiment, when the upper part of the handrail frame 30 is pushed toward the outside of the working floor 12, the load applied to the handrail frame 30 can be supported not only by the edge of the working floor 12 (frame member 20a or frame member 22a), but also by the support portion 18. This makes it possible to prevent a large load from acting on the edge of the working floor 12.

[0047] In particular, in this embodiment, the receiving portion 18 can receive the load from the abutment portion 44 at a position spaced downward from the frame members 20a, 22a. This allows the receiving portion 18 to receive a sufficient load, and therefore it is possible to sufficiently prevent a large load from acting on the edge portion of the work floor 12.

[0048] (Variation) As shown in FIG. 3, in the above-described embodiment, holes 20c, 22c and receiving portions 18 are provided at both ends of cylindrical bodies 21d, 23d. However, holes 20c, 22c and receiving portions 18 may not be provided on cylindrical bodies 21d, 23d. In this case, for example, as shown in FIG. 10, a columnar reinforcing member 56 may be provided to connect receiving portion 18 provided on cylindrical body 21a to reinforcing member 20d closest to cylindrical body 21a at the center of working floor 12 in the long side direction. By providing reinforcing member 56 in this manner, receiving portion 18 can be supported from the inside of working floor 12 in the short side direction, allowing receiving portion 18 to bear a sufficient load. Although detailed description is omitted, the same applies to receiving portions 18 provided on cylindrical bodies 21b, 23a, 23b at the center of working floor 12 in the long side direction.

[0049] In the above embodiment, the case where the worker moves the connecting member 48 relative to the receiving portion 18 by pulling the connecting member 48 has been described. However, for example, as shown in FIG. 11, a beveled surface 49 may be provided at the tip of the connecting portion 48b so that the connecting member 48 moves when pressed by the abutment portion 44.

[0050] In the above embodiment, the case where the receiving portion 18 and the abutting portion 44 are connected by a hook-shaped connecting member 48 has been described, but the shape of the connecting member 48 is not limited to the above example. For example, as shown in Fig. 12, a rod-shaped connecting member 48 may be used. Note that the connecting member 48 shown in Fig. 12 is biased toward the inside of the receiving portion 18 by a biasing member 50 provided on the outside of the receiving portion 18.

[0051] Furthermore, in the above embodiment, the case where the connecting member 48 is biased by the biasing member 50 has been described, but the biasing member 50 may not be provided. For example, as shown in Fig. 13, the connecting member 48 may be moved by an operator to be fixed at a position where it is removed from the receiving portion 18 and at a position where it is inserted into the receiving portion 18.

[0052] In the above-described embodiment, the abutment portion 44 has a cylindrical shape. However, as shown in FIG. 14, the abutment portion 44 may have a rectangular tubular shape. In the above-described embodiment, the receiving portion 18 has a U-shape when viewed from above. However, as shown in FIG. 14, the receiving portion 18 may have an L-shape when viewed from above. In the above-described embodiment, the pair of receiving portions 18 provided at the corners of the working floor 12 are formed by separate members. However, as shown in FIG. 15, the pair of receiving portions 18 provided at the corners of the working floor 12 may be integrally formed. In the example shown in FIG. 15, the pair of receiving portions 18 are integrally formed so that the back plate portion 18a of one receiving portion 18 is continuous with the back plate portion 18a of the other receiving portion 18. In this way, when the pair of receiving portions 18 are integrally formed, the rigidity of the receiving portions 18 can be improved without providing a reinforcing member.

[0053] In the above embodiment, the case where the receiving portion 18 has the back plate portion 18a and the side plate portions 18b has been described, but the configuration of the receiving portion 18 is not limited to the above example as long as the receiving portion 18 is configured to be able to receive a load directed from the abutment portion 44 toward the inside of the work floor 12. For example, the receiving portion 18 does not have to have the back plate portion 18a. In this case, too, the receiving portion 18 (side plate portions 18b) can receive a load from the abutment portion 44 via the connecting member 48. This makes it possible to prevent a large load from being applied from the handrail frame 30 to the frame members 20a, 22a.

[0054] In the above embodiment, a case has been described in which a receiving portion 18 is provided for each of a pair of handrail posts 32 of the handrail frame 30, but it is not necessary for a receiving portion 18 to be provided for one of the handrail posts 32 of the handrail frame 30.
