Summary of the Invention

Problems to be Solved by the Invention

[0004] In Patent Document 1, the bracket and handrail are fixed to a vertical frame member extending vertically in the workbench body using the method described above. Therefore, the handrail in Patent Document 1 can only be attached if there is sufficient vertical space in the vertical frame member relative to the vertical length of the bracket. In other words, if the height of the workbench body (the top plate on which a person stands and works) is relatively low, or if the height difference of the steps on the workbench body is relatively small, and the vertical space in the workbench body is limited, then the handrail fixing device disclosed in Patent Document 1 cannot be applied.

Mode for Carrying Out the Invention

[0014] Hereinafter, with reference to the drawings, a workbench unit according to an embodiment of the present invention and a handrail-equipped workbench assembled from the workbench unit will be described. In the following drawings, for convenience of explanation, some components may be omitted as appropriate. Also, the dimensions of the components shown in the following drawings may not necessarily correspond to the dimensions of the actual components.

[0015] <1. Handrail-equipped workbench> FIG. 1 is a perspective view showing the configuration of a handrail-equipped workbench 1 (hereinafter, also simply referred to as "workbench 1") according to the present embodiment, and FIG. 2 is a perspective view of the workbench 1 with the handrail member 6 omitted. In FIG. 2, for convenience of explanation, the top plate 20 described later is made transparent. The workbench 1 is a platform arranged at an appropriate position for people to climb up and work. Hereinafter, the description will be based on the vertical, horizontal, and front-rear directions defined in FIG. 1, but the definition in FIG. 1 does not limit the direction of the workbench 1. The workbench 1 according to the present embodiment includes at least a top plate member 2, leg members 3a, 3b, horizontal panel members 4a, 4b, mounting members 5a, 5b, and a handrail member 6. Each member will be described below.

[0016] [Top plate] The top plate member 2 is a member that provides a space for a person to stand on, and is generally plate-shaped. The top plate member 2 according to this embodiment comprises a plate-shaped top plate 20 having an upper surface and a lower surface, and support members 21a to 21d that support the top plate 20. The top plate 20 according to this embodiment is a plate-shaped member having an upper surface and a lower surface that are rectangular when viewed from above, and in the top plate member 2, the upper surface faces upward and the lower surface faces downward.

[0017] [Support column member] The support members 21a to 21d are members that reinforce the top plate 20 and enable the top plate 20 to be connected to other members. In this embodiment, the support members 21a to 21d are each rod-shaped members that extend in the front-rear direction, with support members 21a and 21b positioned at both ends of the top plate 20 in the left-right direction, and support members 21c and 21d positioned in the center of the top plate 20 in the left-right direction. Each of the support members 21a to 21d has an upper wall portion, a lower wall portion, and two side wall portions that define a roughly rectangular cross-sectional shape. The upper wall portion and the lower wall portion are each plate-shaped portions that are roughly rectangular when viewed from above. The two side wall portions are each plate-shaped portions that are continuous with both ends of the upper wall portion and the lower wall portion in the left-right direction, and connect the upper wall portion and the lower wall portion with a gap in the vertical direction. Each of the support members 21a to 21d is fixed to the top plate 20 in contact with the lower surface of the top plate 20 at its upper wall portion. The method of fixing the support members 21a to 21d to the top plate 20 is not particularly limited and may be done by welding or by using known fixing members as appropriate. In this embodiment, the support members 21a to 21d and the top plate 20 are fixed by rivets that penetrate both the upper wall portions of the support members 21a to 21d and the top plate 20. This forms a single top plate member 2 in which the top plate 20 and the support members 21a to 21d are integrated.

[0018] The front-to-rear ends of the support members 21a to 21d are formed with fixing portions that enable fastening to the leg members 3 and the mounting members 5a and 5b. The fixing portion includes a nut-type member, such as a nut insert, which has a female thread that can be screwed into the tip of a bolt. The fixing portion according to this embodiment includes the nut-type member and a metal member that is pre-fixed to the nut-type member. The metal member is pre-fixed to at least one of the upper wall portion, lower wall portion, and side wall portion, and has a through hole that serves as an entry point for the female thread of the nut-type member. The fixing portions formed on each of the support members 21a to 21d are used to fix the leg members 3a and 3b and the mounting members 5a and 5b to the top plate member 2, as will be described later.

[0019] [Legs] Leg members 3a and 3b are members positioned in the front-to-back direction of the tabletop member 2, respectively. Leg member 3a has two legs 30a and 30b extending in the vertical direction, horizontal supports 31a and 32a extending in the left-to-right direction, auxiliary plates 33a and 33b, and connecting members 34a and 34b, and is positioned on the rear side of the tabletop member 2. As shown in Figure 3, leg member 3b has two legs 30c and 30d extending in the vertical direction, horizontal supports 31b and 32b extending in the left-to-right direction, auxiliary plates 33c and 33d, and connecting members 34c and 34d, and is positioned on the front side of the tabletop member 2. The four legs 30a to 30d in this embodiment are connected to the tabletop member 2 via connecting members 34a to 34d so as to be perpendicular to the tabletop 20, as will be described later. As a result, the four leg members 3 can support the top plate member 2 from the mounting surface on which the workbench 1 is placed.

[0020] [leg] Each of the legs 30a to 30d has a pair of left and right side walls extending vertically, defining a roughly U-shaped cross-section, and a middle wall connecting the pair of left and right side walls. The middle walls of the legs 30a to 30d each form a surface facing forward or backward on the workbench 1. Each middle wall has at least four through holes in the vertical direction. Two through holes in the legs 30a to 30d are aligned with two through holes in the corresponding connecting members 34a to 34d. In particular, the legs 30a and 30b have through holes 300a and 300b, respectively, which are aligned with the through hole 341a of the connecting member 34a and the through hole 341b of the connecting member 34b. The through holes 300a and 300b serve as entry points to the female threads of the nut-type members 710a and 710b fixed to the inner walls of the legs 30a and 30b, respectively (see Figures 12 and 14). The remaining two through holes in the legs 30a to 30d are aligned with the two through holes in the corresponding auxiliary plates 33a to 33d. In this embodiment, the legs 30a and 30c are connected to the horizontal panel member 4a, which will be described later, together with the auxiliary plates 33a and 33c and the connecting members 34a and 34c. Similarly, the legs 30b and 30d are connected to the horizontal panel member 4b, which will be described later, together with the auxiliary plates 33b and 33d and the connecting members 34b and 34d. The length of the legs 30a to 30d in this embodiment is approximately 10 cm to 40 cm. In other words, the workbench 1 according to this embodiment is configured to be at a height that allows an adult to place one foot on the support surface and then lift the other foot to stand on the top plate 20.

[0021] [Horizontal support] Each horizontal support column 31a and 31b has an upper wall portion defining a U-shaped cross-section, a lower wall portion, and a side wall portion connecting the upper wall portion and the lower wall portion. Horizontal support column 31a is combined with the top plate member 2 such that the upper and lower wall portions sandwich the top plate member 2 from above and below, and the side wall portion covers the rear end of the top plate member 2. Similarly, horizontal support column 31b is combined with the top plate member 2 such that the upper and lower wall portions sandwich the top plate member 2 from above and below, and the side wall portion covers the front end of the top plate member 2. Three through holes (not shown) are formed at each of the left and right ends of the side wall portion of horizontal support column 31a, and these are aligned with the through holes of connecting members 34a and 34b, respectively. Similarly, three through-holes (not shown) are formed at each of the left and right ends of the side wall portion of the horizontal support column 31b, and these are aligned with the through-holes of the connecting members 34c and 34d, respectively. Furthermore, two through-holes (not shown) are formed at the center of the left and right ends of the side walls portion of the horizontal support columns 31a and 31b, respectively. Bolts 36 are inserted through these through-holes (see Figures 3 and 4). The tips of the bolts 36 are screwed into the nut-type members of the fixing parts at both ends of the support members 21c and 21d of the top plate member 2. In this way, the horizontal support column 31a is connected to the support members 21c and 21d, and the horizontal support column 31b is connected to the support members 21c and 21d, respectively.

[0022] [Horizontal supports and auxiliary plates] The horizontal support column 32a extends parallel to the horizontal support column 31a and is a rod-shaped member that reinforces the workbench 1. Similarly, the horizontal support column 32b extends parallel to the horizontal support column 31b and is a rod-shaped member that reinforces the workbench 1. As shown in Figure 4, in this embodiment, the horizontal support column 32a is connected to the leg 30a via a roughly T-shaped auxiliary plate 33a, and to the leg 30b via a roughly T-shaped auxiliary plate 33b. Also, as shown in Figure 3, the horizontal support column 32b is connected to the leg 30c via a roughly T-shaped auxiliary plate 33c, and to the leg 30d via a roughly T-shaped auxiliary plate 33d. More specifically, both ends of the horizontal support column 32a are fixed to the auxiliary plates 33a and 33b, respectively, with rivets, and the auxiliary plate 33a and leg 30a, and the auxiliary plate 33b and leg 30b are fixed with rivets, etc., inserted through aligned through holes. Similarly, both ends of the horizontal support column 32b are fixed to the auxiliary plates 33c and 33d with rivets or the like, and the auxiliary plate 33c and the leg 30c, and the auxiliary plate 33d and the leg 30d are fixed together with rivets or the like inserted through aligned through holes.

[0023] [Connecting members] The connecting members 34a and 34b are configured to connect the horizontal support column 31a to the legs 30a and 30b, and also to connect them to the top plate member 2. Similarly, the connecting members 34c and 34d are configured to connect the horizontal support column 31b to the legs 30c and 30d, and also to connect them to the top plate member 2. However, as will be described later, mounting members 5a and 5b are further fixed to the connecting members 34a and 34b, so the connecting members 34c and 34d will be described first. As shown in Figure 3, the connecting member 34c has a roughly L-shaped front portion that partially overlaps the front of the horizontal support column 31b and the front of the legs 30c, a top portion that rises rearward from the front portion and partially overlaps the top surface of the horizontal support column 31b, and a left portion that rises rearward from the front portion and partially overlaps the left side of the legs 30c. The top, front, and left sides of the connecting member 34c are perpendicular to each other, forming a single corner, which overlaps with the corner of the horizontal support 31b. The connecting member 34d has a substantially L-shaped front section that partially overlaps the front of the horizontal support 31b and the front of the leg 30d, a top section that rises rearward from the front section and partially overlaps the top of the horizontal support 31b, and a right section that rises rearward from the front section and partially overlaps the right side of the leg 30d. The top, front, and right sides of the connecting member 34d are perpendicular to each other, forming a single corner, which overlaps with the corner of the horizontal support 31b. The connecting members 34c and 34d may have the same configuration or they may have different configurations.

[0024] The connecting members 34c and 34d each have five through holes (not shown). Of the through holes in the connecting member 34c, three are aligned with the three through holes at the left end of the horizontal support column 31b, and the remaining two are aligned with the two through holes in the leg 30c. Of the five through holes in the connecting member 34d, three are aligned with the three through holes at the right end of the horizontal support column 31b, and the remaining two are aligned with the two through holes in the leg 30d. Fixing members such as rivets 35 and bolts 36 are inserted into each through hole as appropriate, as needed. In this embodiment, the connecting member 34c is fixed to the horizontal support column 31b using two rivets 35 inserted through two of its through holes, and fixed to the leg 30c using one rivet 35 inserted through one of its through holes. Similarly, the connecting member 34d according to this embodiment is fixed to the horizontal support column 31b using two rivets 35 inserted through two through holes, and fixed to the leg 30d using one rivet 35 inserted through one through hole. As a result, the legs 30c and 30d, the horizontal support column 31b, the horizontal support column 32b, the auxiliary plates 33c and 33d, and the connecting members 34c and 34d are integrated to form a single leg member 3b. Furthermore, the leg member 3b and the support column member 21a are connected by inserting a bolt 36 through a single aligned through hole in the connecting member 34c and the horizontal support column 31b and screwing it into a nut-type component of the support column member 21a of the top plate member 2. In addition, the leg member 3b and the support member 21b are connected by inserting bolts 36 through the aligned through holes of the connecting member 34d and the horizontal support member 31b and screwing them into the nut-type members of the support member 21b of the top plate member 2. The remaining aligned through holes of the connecting member 34c and the leg 30c are used to connect to the horizontal panel member 4a, and the remaining aligned through holes of the connecting member 34d and the leg 30d are used to connect to the horizontal panel member 4b.

[0025] Figure 4 is a perspective view of the workbench 1 from the leg member 3a side. However, the mounting members 5a and 5b, and the handrail member 6 are not shown in Figure 4. Hereinafter, the workbench 1 excluding the mounting members 5a and 5b and the handrail member 6 may be referred to as the "workbench body 9". The connecting member 34a has a roughly L-shaped rear portion that partially overlaps the rear surface of the horizontal support 31a and the rear surface of the leg 30a, a top portion that rises forward from the rear portion and partially overlaps the top surface of the horizontal support 31a, and a left portion that rises forward from the rear portion and partially overlaps the left side of the leg 30a. The connecting member 34b has a roughly L-shaped rear portion that partially overlaps the rear surface of the horizontal support 31a and the rear surface of the leg 30b, a top portion that rises forward from the rear portion and partially overlaps the top surface of the horizontal support 31a, and a right portion that rises forward from the rear portion and partially overlaps the right side of the leg 30b. Connecting members 34a and 34b each have five through holes, similar to connecting members 34c and 34d. Figure 4 shows two of these through holes, 340a, 341a and 340b, 341b. Connecting members 34a and 34b may each have the same configuration as connecting members 34c and 34d. Alternatively, connecting members 34a to 34d may each have different configurations.

[0026] Of the through holes in the connecting member 34a, three through holes, including through hole 340a, are aligned with the three through holes at the left end of the horizontal support column 31a, and the remaining two through holes, including through hole 341a, are aligned with the two through holes in the leg 30a. The connecting member 34a and the horizontal support column 31a are fixed together by rivets 35 inserted through the three through holes excluding through holes 340a and 341a, and the connecting member 34a and the leg 30a are fixed together. Similarly, of the through holes in the connecting member 34b, three through holes, including through hole 340b, are aligned with the three through holes at the right end of the horizontal support column 31a, and the remaining two through holes, including through hole 341b, are aligned with the two through holes in the leg 30b. Rivets 35 inserted through the three through holes, excluding through holes 340b and 341b, are used to fix the connecting member 34b to the horizontal support 31a, and to fix the connecting member 34b to the leg 30b. As a result, the legs 30a and 30b, the horizontal support 31a, the horizontal support 32a, the auxiliary plates 33a and 33b, and the connecting members 34a and 34b are integrated to form a single leg member 3a. Here, the rivet 35 located between through holes 340a and 341a is referred to separately from rivet 35a. The head 350a of rivet 35a protrudes from the outer surface of the connecting member 34a. Similarly, the rivet 35 located between through holes 340b and 341b is referred to separately from rivet 35b. The head 350b of rivet 35b protrudes from the outer surface of the connecting member 34b. Rivets 35a and 35b are examples of fastening members of the present invention, and heads 350a and 350b are examples of protrusions of the present invention.

[0027] The mounting member 5a and the handrail member 6 are attached to the connecting member 34a via two vertically aligned through holes 340a and 341a, and the mounting member 5b and the handrail member 6 are attached to the connecting member 34b via two vertically aligned through holes 340b and 341b. As will be described later, the through hole 340a is aligned with the through hole 210a (see Figure 12) formed at one end of the support member 21a, and is also aligned with the through holes 520a, 5140a and 5120a (see Figure 5) of the mounting member 5a, and the through holes 6120a and 6140a (see Figure 9) of the handrail member 6. Furthermore, the through-hole 341a is aligned with the through-hole 300a (see Figure 12) formed in the leg 30a, and also with the through-holes 521a, 5141a, and 5121a of the mounting member 5a (see Figures 5 and 6), and the through-holes 6121a and 6141a of the handrail member 6 (see Figure 9). Similarly, the through-hole 340b is aligned with the through-hole 210b (see Figure 14) formed at one end of the support member 21b, and also with the through-holes 520b, 5140b, and 5120b of the mounting member 5b (see Figure 7), and the through-holes 6120b and 6140b of the handrail member 6 (see Figure 9). Furthermore, the through-hole 341b is aligned with the through-hole 300b (see Figure 14) formed in the leg 30b, and also with the through-holes 521b, 5141b, and 5121b of the mounting member 5b (see Figures 7 and 8), as well as the through-holes 6121b and 6141b of the handrail member 6 (see Figure 9).

[0028] [Horizontal panel component] The horizontal panel members 4a and 4b are positioned on the left and right sides of the workbench 1, respectively, to reinforce the workbench 1. In this embodiment, the horizontal panel member 4a includes two rod-shaped horizontal members extending parallel to the support member 21a on the workbench 1, and two rod-shaped vertical members extending vertically and connecting the two horizontal members, and these are fixed in place beforehand. Similarly, the horizontal panel member 4b includes two rod-shaped horizontal members extending parallel to the support member 21b on the workbench 1, and two rod-shaped vertical members extending vertically and connecting the two horizontal members, and these are fixed in place beforehand. The horizontal panel member 4a is fixed to the leg members 3a and 3b by connecting one end of the two horizontal members to the leg 30a and the other end to the leg 30c. The method of connecting the horizontal panel member 4a to the legs 30a and 30c is not particularly limited, but can be done, for example, using bolts. The bolts can also be used to connect the auxiliary plate 33a and the leg 30a, the auxiliary plate 33c and the leg 30c, the connecting member 34a and the leg 30a (bolt 71a), and the connecting member 34c and the leg 30c (bolt 36). These bolts may be screwed into separate nuts, or into nut-type members that are pre-formed integrally at both ends of the two horizontal members of the horizontal panel member 4a. Similarly, the method of connecting the horizontal panel member 4b and the legs 30b and 30d is not particularly limited, but can be done using bolts, for example. The bolts can also be used to connect the auxiliary plate 33b and the leg 30b, the auxiliary plate 33d and the leg 30d, the connecting member 34b and the leg 30b (bolt 71b), and the connecting member 34d and the leg 30d (bolt 36). These bolts may be screwed into separate nuts, or they may be nut-type members that are pre-formed integrally at both ends of the two horizontal members of the horizontal panel member 4b.

[0029] [Mounting components] Figure 5 is a perspective view of the mounting member 5a, and Figure 6 is another perspective view of the mounting member 5a. The mounting member 5a is formed in a cylindrical shape with both ends open, and on the workbench 1, it is positioned so that both ends face vertically. The mounting member 5a has a bracket portion 51a, a wall portion 52a, a connecting portion 53a, and a connecting portion 54a. The bracket portion 51a is a hollow, pipe-shaped portion with both ends open, defined by the side wall portions 511a to 514a. The bracket portion 51a is configured to accommodate the mounting portion 610a of the handrail member 6, which will be described later. The wall portion 52a is a flat plate-shaped portion that extends vertically, and on the workbench 1, it faces and contacts the connecting member 34a. The connecting portions 53a and 54a are flat plate-shaped portions that extend vertically, and connect the wall portion 52a and the bracket portion 51a. More specifically, the connecting portion 53a and the connecting portion 54a are continuous with both ends of the wall portion 52a in the left-right direction and with both ends of the side wall portion 514a in the left-right direction, respectively, so that there is a certain distance between the wall portion 52a and the side wall portion 514a in the front-rear direction.

[0030] The side wall portions 512a, 514a, and 52a are parallel to each other (however, they do not need to be strictly parallel). A through hole 5120a is formed in the side wall portion 512a, a through hole 5140a in the side wall portion 514a, and a through hole 520a in the wall portion 52a, each at the same position in the vertical and horizontal directions. In addition, a through hole 5121a is formed in the side wall portion 512a, a through hole 5141a in the side wall portion 514a, and a through hole 521a in the wall portion 52a, each at the same position in the vertical and horizontal directions. The through holes 5120a, 5140a, and 520a are aligned with the through holes 6140a and 6120a of the mounting portion 610a, which will be described later, on the workbench 1, and bolts 70a, which will be described later, are inserted through these through holes. Furthermore, the through holes 5121a, 5141a, and 521a are aligned with the through holes 6141a and 6121a of the mounting portion 610a, which will be described later, on the workbench 1, and bolts 71a, which will be described later, are inserted through these through holes.

[0031] Furthermore, a through hole 522a is formed in the wall portion 52a. The through hole 522a is formed to a size larger than the maximum diameter of the rivet 35a that connects the leg 30a and the connecting member 34a. As a result, in the workbench 1, the head 350a of the rivet 35a protruding from the outer surface of the connecting member 34a passes through the through hole 522a and is positioned between the wall portion 52a and the side wall portion 514a (see Figure 12). In this embodiment, a through hole 5142a, which has the same size as the through hole 522a, is formed in the side wall portion 514a at a position opposite to the through hole 522a.

[0032] A through hole 5110a is formed in the side wall portion 511a. The through hole 5110a is aligned with the through hole 6110a of the mounting portion 610a, which will be described later, on the workbench 1.

[0033] In the side wall portion 512a, a through hole 5122a is further formed between the through hole 5120a and the through hole 5121a. The through hole 5122a is aligned with the through hole 6122a of the mounting portion 610a, which will be described later, on the workbench 1.

[0034] Figure 7 is a perspective view of the mounting member 5b, and Figure 8 is another perspective view of the mounting member 5b. The mounting member 5b has the same configuration as the mounting member 5a, except that the positional relationship between the connecting parts 53b and 54b, and the side wall parts 511b and 513b, with respect to the wall part 52b is reversed compared to the positional relationship in the mounting member 5a. That is, the through holes 5120b, 5140b, and 520b are aligned with the through holes 6140b and 6120b of the mounting part 610b described later on the workbench 1, and bolts 70b described later are inserted through these through holes. The through holes 5121b, 5141b, and 521b are aligned with the through holes 6141b and 6121b of the mounting part 610b described later on the workbench 1, and bolts 71b described later are inserted through these through holes. A through hole 5110b is formed in the side wall portion 511b. The through hole 5110b is aligned with the through hole 6110b of the mounting portion 610b, which will be described later, on the workbench 1. In the side wall portion 512b, a through hole 5122b is further formed between the through hole 5120b and the through hole 5121b. The through hole 5122b is aligned with the through hole 6122b of the mounting portion 610b, which will be described later, on the workbench 1. In this way, in the mounting member 5b, the elements corresponding to the mounting member 5a are given the same numerical designation as the mounting member 5a. The other components of the mounting member 5b are described in the same way as the corresponding components of the mounting member 5a, so the description is omitted.

[0035] The materials constituting the mounting members 5a and 5b are not particularly limited, but in this embodiment they are metal. The mounting members 5a and 5b according to this embodiment are each integrally constructed.

[0036] [Handrail components] The handrail member 6 has two handrail support sections 61a and 61b and a support section 62 (see Figure 1). The handrail support sections 61a and 61b in this embodiment are each made of hollow pipe-shaped members and extend vertically on the workbench 1. The support section 62 is continuous with the upper end of the handrail support section 61a and the upper end of the handrail support section 61b on the workbench 1 and connects the handrail support sections 61a and 61b. The support section 62, the handrail support sections 61a and 61b in this embodiment are integrally formed from hollow pipe-shaped members. On the workbench 1, the lower end of the handrail support section 61a becomes a mounting section 610a that can be attached to the mounting member 5a. Similarly, the lower end of the handrail support section 61b becomes a mounting section 610b that can be attached to the mounting member 5b.

[0037] Figure 9 is a perspective view showing cross-sections of the mounting portion 610a and the mounting portion 610b. As shown in Figure 9, the mounting portion 610a has a rounded, substantially rectangular cross-sectional shape composed of side wall portions 611a to 614a, and the mounting portion 610b has a rounded, substantially rectangular cross-sectional shape composed of side wall portions 611b to 614b. When the mounting portion 610a is housed in the bracket portion 51a of the mounting member 5a, the side wall portion 611a faces the side wall portion 511a, the side wall portion 612a faces the side wall portion 512a, the side wall portion 613a faces the side wall portion 513a, and the side wall portion 614a faces the side wall portion 514a. Similarly, when the mounting portion 610b is housed in the bracket portion 51b of the mounting member 5b, the side wall portion 611b faces the side wall portion 511b, the side wall portion 612b faces the side wall portion 512b, the side wall portion 613b faces the side wall portion 513b, and the side wall portion 614b faces the side wall portion 514b.

[0038] Figure 10 is an enlarged perspective view of the mounting portion 610a. As shown in Figure 10, a through hole 6140a is formed in the side wall portion 614a, and a through hole 6120a is formed in the side wall portion 612a, at the same positions in the vertical and horizontal directions, respectively. Furthermore, a through hole 6141a is formed in the side wall portion 614a, and a through hole 6121a is formed in the side wall portion 612a, at the same positions in the vertical and horizontal directions, respectively. Bolts 70a, which will be described later, are inserted through the through holes 6140a and 6120a. Furthermore, bolts 71a, which will be described later, are inserted through the through holes 6141a and 6121a.

[0039] In this embodiment, a through hole 6142a is further formed in the side wall portion 614a. The through hole 6142a has the same size as the through holes 522a and 5142a and is aligned with the through holes 522a and 5142a on the workbench 1.

[0040] A through hole 6110a is formed in the side wall portion 611a. The through hole 6110a is aligned with the through hole 5110a on the workbench 1. Bolts 72a, which will be described later, are inserted through the through holes 6110a and 5110a.

[0041] In the side wall portion 612a, a through hole 6122a is further formed between the through holes 6120a and 6121a. The through hole 6122a is aligned with the through hole 5122a on the workbench 1. Bolts 73a, which will be described later, are inserted through the through holes 6122a and 5122a.

[0042] Figure 11 is an enlarged perspective view of the mounting portion 610b. As shown in Figure 11, a through hole 6140b is formed in the side wall portion 614b, and a through hole 6120b is formed in the side wall portion 612b, at the same positions in the vertical and horizontal directions, respectively. Furthermore, a through hole 6141b is formed in the side wall portion 614b, and a through hole 6121b is formed in the side wall portion 612b, at the same positions in the vertical and horizontal directions, respectively. Bolts 70b, which will be described later, are inserted through the through holes 6140b and 6120b. Furthermore, bolts 71b, which will be described later, are inserted through the through holes 6141b and 6121b.

[0043] In this embodiment, a through hole 6142b is further formed in the side wall portion 614b. The through hole 6142b has the same size as the through holes 522b and 5142b and is aligned with the through holes 522b and 5142b on the workbench 1.

[0044] A through hole 6110b is formed in the side wall portion 611b. The through hole 6110b is aligned with the through hole 5110b on the workbench 1. Bolts 72b, which will be described later, are inserted through the through holes 6110b and 5110b.

[0045] In the side wall portion 612b, a through hole 6122b is further formed between the through holes 6120b and 6121b. The through hole 6122b is aligned with the through hole 5122b on the workbench 1. Bolts 73b, which will be described later, are inserted through the through holes 6122b and 5122b.

[0046] The length from the lowest end of the handrail member 6 (the lower ends of the mounting portions 610a and 610b) to the uppermost end of the handrail member 6 is not particularly limited, but in order to function as a handrail, it is preferably 70 cm or more, more preferably 80 cm or more, and even more preferably 90 cm or more. In particular, the height from the upper surface of the top plate 20 to the upper end of the support column connecting portion 62 is preferably 85 cm or more. The material constituting the handrail member 6 is not particularly limited, but in this embodiment it is metal.

[0047] [Fastening components] Figure 12 shows the connecting member 34a and the mounting member 5a viewed from the left side of the workbench 1, and Figure 13 shows the connecting member 34a and the mounting member 5a viewed from above. As shown in Figures 12 and 13, the bolt 70a passes through the side wall portion 512a (through hole 5120a), side wall portion 612a (through hole 6120a), side wall portion 614a (through hole 6140a), side wall portion 514a (through hole 5140a), wall portion 52a (through hole 520a), and connecting member 34a (through hole 340a) in this order, and then passes through the through hole 210a of the support member 21a. The tip of the bolt 70a is screwed into the nut-type member 700a included in the fixing part of the support member 21a. As a result, bolt 70a connects the connecting member 34a, the mounting member 5a, the mounting portion 610a, and the support member 21a. Bolt 71a passes through the side wall portion 512a (through hole 5121a), side wall portion 612a (through hole 6121a), side wall portion 614a (through hole 6141a), side wall portion 514a (through hole 5141a), wall portion 52a (through hole 521a), and connecting member 34a (through hole 341a) in this order, and then passes through the through hole 300a of leg 30a. The tip of bolt 71a is screwed into the nut-type member 710a of leg 30a. As a result, bolt 71a connects the connecting member 34a, the mounting member 5a, the mounting portion 610a, and leg 30a. Bolts 70a and 71a are examples of fastening members of the present invention.

[0048] In this embodiment, the mounting portion 610a is further connected to the mounting member 5a by bolt 72a and nut-type member 720a, and bolt 73a and nut-type member 730a. Bolt 72a passes through through holes 5110a and 6110a in that order and screws into nut-type member 720a. Nut-type member 720a has a female thread that is pre-formed on the inside of the pipe constituting the mounting portion 610a and has an entrance through hole 6110a. Bolt 73a passes through through holes 5122a and 6122a in that order, and nut-type member 730a has a female thread that is pre-formed on the inside of the pipe constituting the mounting portion 610a and has an entrance through hole 6122a.

[0049] Figure 14 shows the connecting member 34b and the mounting member 5b viewed from the right side of the workbench 1, and Figure 15 shows the connecting member 34b and the mounting member 5b viewed from above. As shown in Figures 14 and 15, the bolt 70b passes through the side wall portion 512b (through hole 5120b), side wall portion 612b (through hole 6120b), side wall portion 614b (through hole 6140b), side wall portion 514b (through hole 5140b), wall portion 52b (through hole 520b), and connecting member 34b (through hole 340b) in this order, and then passes through the through hole 210b of the support member 21b. The tip of the bolt 70b is screwed into the nut-type member 700b included in the fixing part of the support member 21b. As a result, bolt 70b connects the connecting member 34b, the mounting member 5b, the mounting portion 610b, and the support member 21b. Bolt 71b passes through the side wall portion 512b (through hole 5121b), side wall portion 612b (through hole 6121b), side wall portion 614b (through hole 6141b), side wall portion 514b (through hole 5141b), wall portion 52b (through hole 521b), and connecting member 34b (through hole 341b) in this order, and then passes through the through hole 300b of leg 30b. The tip of bolt 71b is screwed into the nut-type member 710b of leg 30b. As a result, bolt 71b connects the connecting member 34b, the mounting member 5b, the mounting portion 610b, and leg 30b. Bolts 70b and 71b are examples of fastening members of the present invention.

[0050] In this embodiment, the mounting portion 610b is further connected to the mounting member 5b by bolt 72b and nut-type member 720b, bolt 73b and nut-type member 730b. Bolt 72b passes through through holes 5110b and 6110b in that order and screws into nut-type member 720b. Nut-type member 720b is pre-formed on the inside of the pipe constituting the mounting portion 610b and has a female thread that enters through hole 6110b. Bolt 73b passes through through holes 5122b and 6122b in that order and screws into nut-type member 730b. Nut-type member 730b is pre-formed on the inside of the pipe constituting the mounting portion 610b and has a female thread that enters through hole 6110b.

[0051] <2. How to assemble the workbench> The workbench 1 according to this embodiment is manufactured by assembling a workbench unit. The workbench unit comprises, for example, a top plate member 2, leg members 3a and 3b, side panel members 4a and 4b, mounting members 5a and 5b, handrail member 6, bolts 70a to 73a, bolts 70b to 73b, bolt 36, and other bolts, each in a separate state. In the state of the workbench unit, the space required for transportation can be reduced compared to the state of the workbench 1, and the packaging work is also easier. The packaging of the workbench unit is unpacked at the place where the workbench 1 is to be used. Then, the leg members 3a and 3b are attached to the top plate member 2 using bolts 36. Subsequently, the side panel members 4a and 4b are connected to the leg members 3a and 3b using bolts 36 and other bolts. This gives the main body of the workbench 9. The procedure for attaching the handrail member 6 to the main body of the workbench 9 via mounting members 5a and 5b will be described below.

[0052] First, the mounting members 5a and 5b are attached to the handrail member 6. Specifically, the mounting portion 610a is fitted into the bracket portion 51a of the mounting member 5a, and the mounting portion 610b is fitted into the bracket portion 51b of the mounting member 5b. At this time, the mounting portion 610a and the bracket portion 51a are positioned so that the side wall portions 611a and 511a, 612a and 512a, 613a and 513a, and 614a and 514a face each other. Similarly, the mounting portion 610b and the bracket portion 51b are positioned so that the side wall portions 611b and 511b, 612b and 512b, 613b and 513b, and 614b and 514b face each other.

[0053] Next, the through holes of the mounting member 5a and the mounting portion 610a are aligned, and bolts 72a are inserted through the through holes 5110a and 6110a and fixed to the nut-type member 720a on the inside of the side wall portion 611a. Also, bolts 73a are inserted through the through holes 5122a and 6122a and fixed to the nut-type member 730a on the inside of the side wall portion 612a. This connects the mounting portion 610a to the mounting member 5a. Similarly, the through holes of the mounting member 5b and the mounting portion 610b are aligned, and bolts 72b are inserted through the through holes 5110b and 6110b and fixed to the nut-type member 720b on the inside of the side wall portion 611b. Also, bolts 73b are inserted through the through holes 5122b and 6122b and fixed to the nut-type member 730b on the inside of the side wall portion 612b. This connects the mounting portion 610b to the mounting member 5b.

[0054] Next, insert bolts 70a through through holes 5120a, 6120a, 6140a, 5140a, and 520a, and insert bolts 71a through through holes 5121a, 6121a, 6141a, 5141a, and 521a. Similarly, insert bolts 70b through through holes 5120b, 6120b, 6140b, 5140b, and 520b, and insert bolts 71b through through holes 5121b, 6121b, 6141b, 5141b, and 521b.

[0055] Next, the mounting member 5a and mounting portion 610a are fixed to the connecting member 34a, and the mounting member 5b and mounting portion 610b are fixed to the connecting member 34b. Specifically, the tip of the bolt 70a is inserted through the through hole 340a of the connecting member 34a and the through hole 210a of the support member 21a, and fixed to the nut-type member 700a of the support member 21a. Similarly, the tip of the bolt 71a is inserted through the through hole 341a of the connecting member 34a and the through hole 300a of the leg 30a, and fixed to the nut-type member 710a of the leg 30a. Likewise, the tip of the bolt 70b is inserted through the through hole 340b of the connecting member 34b and the through hole 210b of the support member 21b, and fixed to the nut-type member 700b of the support member 21b. Furthermore, the tip of the bolt 71b is inserted through the through hole 341b of the connecting member 34b and the through hole 300b of the leg 30b, and fixed to the nut-type member 710b of the leg 30b.

[0056] In this case, the head 350a of the rivet 35a that fixes the leg 30a and the connecting member 34a passes through the through hole 522a of the mounting member 5a, so it does not interfere with the mounting member 5a. Therefore, when bringing the mounting member 5a closer to the connecting member 34a, the head 350a can be fitted into the through hole 522a, and the head 350a and the through hole 522a can be used as a guide for alignment. Similarly, the head 350b of the rivet 35b that fixes the leg 30b and the connecting member 34b passes through the through hole 522b of the mounting member 5b, so it does not interfere with the mounting member 5b. Therefore, when bringing the mounting member 5b closer to the connecting member 34b, the head 350b can be fitted into the through hole 522b, and the head 350b and the through hole 522b can be used as a guide for alignment.

[0057] When bolt 70a is properly tightened onto nut-type member 700a, bolt 71a onto nut-type member 710a, bolt 70b onto nut-type member 700b, and bolt 71b onto nut-type member 710b, the mounting members 5a and 5b and the handrail member 6 are fixed to the base body 9, and the workbench 1 is manufactured.

[0058] <3. Features> According to the workbench 1 and workbench unit of the above embodiment, the following effects can be obtained.

[0059] (1) In the workbench 1, the mounting members 5a and 5b for attaching the handrail member 6 are not attached directly to the legs 30a to 30d, but are attached from the outside of the connecting members 34a and 34b. Therefore, even when the legs 30a to 30d are relatively short in the vertical direction and it is difficult to secure space for attaching the handrail member 6 on the legs 30a to 30d, the handrail member 6 can be easily attached. Thus, a workbench 1 can be provided in which a handrail member 6 with sufficient height is attached to a relatively low workbench body 9.

[0060] (2) On the workbench 1, mounting members 5a and 5b for attaching the handrail member 6 are attached near the top plate member 2 (near the upper ends of the legs 30a to 30d). As a result, the portion of the handrail support section 61a and 61b of the handrail member 6 that is located below the top plate member 2 (and does not function as a handrail) can be reduced, and the material can be used effectively.

[0061] (3) In the initial state of the workbench unit, rivets are often used rather than bolts for fixing points (for example, points where parts are fixed to each other in the top plate member 2, leg member 3a, and leg member 3b). According to the workbench 1, even if rivets 35a and 35b are already present in the main body 9 and their heads 350a and 350b protrude from the outer surface of the connecting members 34a and 34b, the mounting members 5a and 5b can be attached without interfering with them. In addition, the through holes 522a and 522b and the heads 350a and 350b can be used as a guide for alignment.

[0062] (4) When the workbench 1 is in use, a backward force is easily applied to the support column connection portion 62 of the handrail member 6, which generates a rotational torque that causes the handrail member 6 to separate from the base body 9 around the mounting members 5a and 5b. On the workbench 1, the handrail member 6 is attached to the base body 9 at a distance from the mounting surface by the mounting members 5a and 5b. Therefore, compared to the case where the handrail member 6 is attached to the base body 9 near the mounting surface, the distance from the center of rotation of the handrail member 6 to the point where the force is applied can be shortened, and the above torque can be reduced. As a result, the load on the handrail member 6, mounting members 5a and 5b, and the members involved in fixing the base body 9 (especially the bolts 70a, 71a, 70b, 71b, etc.) is reduced, and the handrail member 6 is less likely to come off the base body 9.

[0063] <4. Variation> Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the invention. For example, the following modifications are possible. Furthermore, the gist of the following modifications can be combined as appropriate.

[0064] (1) In the above embodiment, the handrail member 6 is attached to the short side of the top plate member 2. However, the handrail member 6 may also be attached to the long side of the top plate member 2. Furthermore, the workbench unit or workbench 1 may be equipped with two or more handrail members 6, and accordingly, it may be equipped with two or more sets of mounting members 5a and 5b.

[0065] (2) The connecting members 34a and 34b are not limited to those of the above embodiment. For example, the workbench unit or the base body 9 of the workbench 1 can be replaced with a base body 9x comprising a top plate member 2, two leg members 3x and 3y, and side plates 4x and 4y, as shown in Figures 16 to 18. The leg member 3x has two legs 30a and 30b and a plate-shaped connecting member 34x that connects them. The connecting member 34x is connected to the leg 30a via a rivet 35a and to the leg 30b via a rivet 35b. The connecting member 34x is further connected to the legs 30a and 30b via bolts 71a and 71b, and is also connected to the top plate member 2 via bolts 70a and 70b. In the above embodiment, the handrail member 6 can be attached to the base body 9x in the same manner as the workbench 1 by attaching the mounting member 5a to the connecting member 34x via bolts 70a and 71a, and the mounting member 5b to the connecting member 34x via bolts 70b and 71b. The leg member 3y has two legs 30c and 30d and a plate-shaped connecting member 34y that connects them. The connecting member 34y is connected to the legs 30c and 30d via rivets 35. The connecting member 34y is further connected to the legs 30c and 30d via bolts 36, and is also connected to the top plate member 2 via bolts 36. The mounting members 5a and 5b may be attached to the connecting member 34y. The top plate member 2 and legs 30a to 30d have the same configuration as the top plate member 2 and legs 30a to 30d of the workbench 1. Side panel 4x is connected to legs 30a and 30c via bolts 37, and is also connected to the top plate member 2. Side panel 4y is connected to legs 30b and 30d via bolts 37, and is also connected to the top plate member 2. Therefore, side panels 4x and 4y are also examples of connecting members, and mounting members 5a and 5b, and handrail members 6 can be attached to them.

[0066] (3) The workbench unit or workbench 1 may include, in addition to or instead of the connecting members 34a and 34b as in the above embodiment, reinforcing members configured to reinforce the connection between the top plate member 2 and the plurality of legs 30a to 30d. In this case, the mounting members 5a and 5b may be configured to be attached to the reinforcing members in addition to or instead of the connecting members 34a and 34b. For example, in the above embodiment and the embodiment of Figure 16, when the top plate member 2 and the legs 30a to 30d are directly fixed, the connecting members 34a to 34d, 34x, 34y, and the side plates 4x, 4y can be said to be reinforcing members.

[0067] (4) The workbench unit or workbench 1 may have only one top plate member 2, or it may have two or more. In other words, the workbench 1 may be configured as a multi-tiered table rather than a single-tiered table.

[0068] (5) The choice between bolts and rivets in the above embodiment is not particularly limited and may be changed as appropriate. The same applies to rivets as fastening members. Furthermore, fastening members are not limited to bolts and nut-type members, and other members may be used. For example, each nut-type member may be configured as a nut separate from the components of the workbench unit.

[0069] (6) The configuration of mounting members 5a and 5b is not limited to that of the above embodiment. For example, the mechanism for avoiding interference with the head 350a of the rivet 35a may be a recess formed in the wall portion 52a, rather than the through hole 522a of the wall portion 52a. The recess may have any shape as long as it is recessed toward the side wall portion 514a more than other parts of the wall portion 52a. Furthermore, the through holes 520b, 521b and 522b of the wall portion 52a may be formed as a single integrated through hole. The mechanism for avoiding interference with the head 350a may be omitted. The same applies to mounting member 5b. Furthermore, mounting members 5a and 5b may be omitted. In other words, the mounting portions 610a and 610b of the handrail member 6 may be fixed to at least one of the connecting members (e.g., 34a~34d, 34x, 34y) and the reinforcing members via fastening members (e.g., bolts 70a, 71a, 70b, 71b).

[0070] (7) The through holes 5110a and 5122a of the mounting member 5a and the corresponding through holes 6110a and 6122a of the mounting portion 610a may be omitted. In other words, the bolt 72a, nut-type member 720a, bolt 73a, and nut-type member 730a may be omitted. The same applies to the mounting member 5b, mounting portion 610b, bolt 72b, nut-type member 720b, bolt 73b, and nut-type member 730b.

[0071] (8) The configuration of the leg members 3a, 3b, 3x, and 3z is not limited to that of the above embodiment. For example, each leg member may be a member in which the legs 30a to 30d are inclined in the vertical direction. Also, the leg member may not be a member in which two or more legs are integrally connected as in the above embodiment, but rather the legs themselves may be configured as separate, distinct parts.
