[0053] According to this embodiment, the first mounting portion 2-1 and the second mounting portion 2-2 are formed in a plate shape, which allows the connector 3-1 to be stably placed on at least one of the first mounting portion 2-1 and the second mounting portion 2-2.

[0054] According to this embodiment, the connector 3 has a first connecting portion 32-1 connecting the first insertion portion 31-1 and the second insertion portion 31-2, and a second connecting portion 32-2 connecting the first insertion portion 31-1 and the third insertion portion 31-3, and the second connecting portion 32-2 is in contact with the first connecting portion 32-1. This prevents misalignment between the first connecting portion 32-1 and the second connecting portion 32-2 when the workbench 1 is moved by rolling the wheels 13. This makes it possible to easily move adjacent workbenches 1 while they are connected to each other.

[0055] According to this embodiment, the chamfered portion 33-1 of the first connecting portion 32-1 and the chamfered portion 33-2 of the second connecting portion 32-2 are in contact with each other. This further reduces or prevents misalignment between the first connecting portion 32-1 and the second connecting portion 32-2 when the workbench 1 is moved by rolling the wheels 13. This makes it possible to easily move adjacently arranged workbenches 1 while they are connected to each other.

[0056] According to this embodiment, the connector 3 has a first connector 32-1 connecting the first insertion portion 31-1 and the second insertion portion 31-2, a second connector 32-2 connecting the first insertion portion 31-1 and the third insertion portion 31-3, and a third connector 32-3 connecting the third insertion portion 31-3 and the fourth insertion portion 31-4. The second connector 32-2 contacts the first connector 32-1 and the third connector 32-3. This prevents misalignment between the first connector 32-1, the second connector 32-2, and the third connector 32-3 when the workbench 1 is moved by rolling the wheels 13. This allows adjacent workbenches 1 to be easily moved while connected to each other.

[0057] According to this embodiment, the connector 3 has a first connector 32-1 that connects the first insertion portion 31-1 and the second insertion portion 31-2, and a second connector 32-2 that connects the first insertion portion 31-1 and the third insertion portion 31-3, and the first connector 32-1 and the second connector 32-2 are integrally formed. This allows the operations of inserting the first insertion portion 31-1 into the first through hole 21-1, inserting the second insertion portion 31-2 into the second through hole 21-2, and inserting the third insertion portion 31-3 into the third through hole 21-3 to be performed simultaneously. This makes it easier to connect work tables 1 to each other.

[0058] The manner in which adjacent workbenches 1 are connected to each other is basically the same in the first direction X and the second direction Y. Therefore, the effect of connecting the first workbench 1-1 and the second workbench 1-2, which are adjacent in the first direction X, is similarly exerted in the connection between the first workbench 1-1 and the third workbench 1-3, which are adjacent in the second direction Y, the connection between the third workbench 1-3 and the fourth workbench 1-4, which are adjacent in the first direction X, and the connection between the second workbench 1-2 and the fourth workbench 1-4, which are adjacent in the second direction Y. This also applies to other embodiments described later.

[0059] (Second embodiment) Next, a connecting structure 100 for a workbench in a second embodiment will be described. Below, configurations similar to those in the above-mentioned embodiments will be omitted. Fig. 6(a) is a front view showing an example of a connector 3 in the second embodiment, and Fig. 6(b) is a bottom view showing an example of a connector 3 in the second embodiment. Fig. 7 is a plan view showing an example of a connecting structure 100 for a workbench in the second embodiment.

[0060] The connector 3 connects the attachment portions 2 together. The connector 3 has two insertion portions 31 and a connecting portion 32 that connects the two insertion portions 31. The connecting portion 32 is formed in a rectangular shape in a plan view.

[0061] The connecting portion 32 contacts two adjacent pillars 12, 12. That is, the first connecting portion 32-1 contacts the first pillar 12-1 and the second pillar 12-2. The second connecting portion 32-2 contacts the first pillar 12-1 and the third pillar 12-3. The third connecting portion 32-3 contacts the third pillar 12-3 and the fourth pillar 12-4. The fourth connecting portion 32-4 contacts the second pillar 12-2 and the fourth pillar 12-4.

[0062] In particular, according to this embodiment, the first connecting portion 32-1 of the connector 3 contacts the first support column 12-1 and the second support column 12-2. This prevents the first work table 1-1 and the second work table 1-2 from rotating about the vertical direction Z as the rotation center axis when the work table 1 is moved by rolling the wheels 13. This makes it possible to easily move adjacently arranged work tables 1 while they are connected to each other.

[0063] (Third embodiment) Next, a connecting structure 100 for a workbench in a third embodiment will be described. Fig. 8(a) is a front view showing an example of a connector 3 in the third embodiment, and Fig. 8(b) is a bottom view showing an example of a connector 3 in the third embodiment. Fig. 9 is a plan view showing an example of a connecting structure 100 for a workbench in the third embodiment.

[0064] The connector 3 connects the mounting portions 2 together. The connector 3 has two insertion portions 31 and a connecting portion 32 that connects the two insertion portions 31. The connecting portion 32 has L-shaped notches 34 formed in each of its two corners.

[0065] The connecting portion 32 contacts two adjacent support columns 12, 12. The support columns 12 contact the cutout portions 34 of the connecting portion 32 from two directions, the first direction X and the second direction Y.

[0066] In particular, according to this embodiment, the first connecting portion 32-1 of the connector 3 has a notch 34 formed at a corner thereof, and the notch 34 comes into contact with the first support column 12-1 and the second support column 12-2. This further prevents the first work table 1-1 and the second work table 1-2 from rotating about the vertical direction Z as the rotation axis when the work table 1 is moved by rolling the wheels 13. This makes it possible to easily move adjacent work tables 1 while they are connected to each other.

[0067] (Fourth embodiment) Next, a connecting structure 100 for a workbench according to a fourth embodiment will be described. Fig. 10 is a front view showing a connector 3 according to the fourth embodiment. Fig. 11 is a plan view showing a first example of the connecting structure 100 for a workbench according to the fourth embodiment. Fig. 12 is a plan view showing a second example of the connecting structure 100 for a workbench according to the fourth embodiment.

[0068] As shown in FIG. 10, the coupler 3 has two insertion sections 31 (one first insertion section 31-1 and one second insertion section 31-2) and a connecting section 32 connecting the two insertion sections 31. The coupler 3 is formed by bending a rod-shaped member, and the insertion sections 31 and the connecting section 32 are each formed in a rod shape. The length of one insertion section 31 is different from the length of the other insertion section 31. Note that the lengths of the two insertion sections 31 may be the same.

[0069] The insertion portion 31 has a retaining portion 35 and a coil spring 36. The retaining portion 35 may be any member capable of fixing the coil spring 36 in a state where it protrudes from the insertion portion 31, and may be a spring pin, rivet, or the like. The coil spring 36 is retained by the retaining portion 35. Since the insertion portion 31 has the retaining portion 35 and the coil spring 36, when the insertion portion 31 is inserted into the through-hole 21, the coil spring 36 comes into contact with the attachment portion 2. The elastic force of the coil spring 36 can maintain the attachment portion 2 and the connecting portion 32 in contact with each other, preventing the coupler 3 from falling off.

[0070] 11, the connecting portions 32 may be arranged in a direction along the first direction X or the second direction Y. As shown in Fig. 12, the connecting portions 32 may be arranged so as to be inclined, for example, at 45° with respect to the first direction X, or so as to be inclined, for example, at 45° with respect to the second direction Y.

[0071] One mounting portion 2 comes into contact with another adjacent mounting portion 2. That is, the first mounting portion 2-1 and the second mounting portion 2-2 come into contact. The third mounting portion 2-3 and the fourth mounting portion 2-4 come into contact. The first mounting portion 2-1 and the third mounting portion 2-3 come into contact. The second mounting portion 2-2 and the fourth mounting portion 2-4 come into contact.

[0072] In particular, according to this embodiment, the first attachment portion 2-1 comes into contact with the second attachment portion 2-2. This allows the first workbench 1-1 and the second workbench 1-2 to be moved stably when the workbench 1 is moved by rolling the wheels 13. This makes it possible to easily move adjacent workbenches 1 while they are connected to each other.

[0073] In particular, according to this embodiment, the first insertion portion 31-1, the second insertion portion 31-2, and the first connecting portion 32-1 are each formed in a rod shape. This allows the second insertion portion 31-2 to be inserted into and removed from the second through-hole 21-2 while the first insertion portion 31-1 is inserted into the first through-hole 21-1. This makes it easy to connect and disconnect the workbench 1.

[0074] In particular, according to this embodiment, the first insertion portion 31-1 has a holding portion 35 that protrudes from the insertion portion 31 and a coil spring 36 that is held by the holding portion 35. The elastic force of the coil spring 36 can maintain the attachment portion 2 and the connecting portion 32 in contact with each other, preventing the coupler 3 from falling off.

[0075] (Fifth embodiment) Next, a connecting structure 100 for a workbench in a fifth embodiment will be described. Fig. 13(a) is a plan view showing a first example of the mounting portion 2 in the fifth embodiment, and Fig. 13(b) is a front view showing the first example of the mounting portion 2 in the fifth embodiment. Fig. 14(a) is a plan view showing a second example of the mounting portion 2 in the fifth embodiment, and Fig. 14(b) is a front view showing the second example of the mounting portion in the fifth embodiment. Fig. 15 is a plan view showing an example of the connecting structure 100 for a workbench in the fifth embodiment.

[0076] As shown in Figures 13 and 14, one mounting part 2 attached to one support 12 uses two separate steel plates. One through hole 21 is formed in each steel plate of the mounting part 2. As shown in Figure 13(b), the heights of the through holes 21 in one mounting part 2 are all the same. However, as shown in Figure 14(b), the heights of the through holes 21 in one mounting part 2 may be different from each other.

[0077] As shown in FIG. 15, one mounting portion 2 attached to one support pole 12 comes into contact with another mounting portion 2 attached to another support pole 12.

[0078] (Sixth embodiment) Next, a connection structure 100 for a workbench according to a sixth embodiment will be described. Figure 16 is a plan view showing the connection structure 100 for a workbench according to the sixth embodiment. The attachment portion 2 may be formed in a triangular shape when viewed from above.

[0079] (Seventh embodiment) Next, a connection structure 100 for a workbench according to a seventh embodiment will be described. Fig. 17(a) is a plan view showing a first example of the mounting portion 2 according to the seventh embodiment, and Fig. 17(b) is a plan view showing a second example of the mounting portion 2 according to the seventh embodiment.

[0080] As shown in Fig. 17, the support 12 is formed in a cylindrical shape and uses a steel pipe having a circular cross section perpendicular to the up-down direction. As shown in Fig. 17(a), the mounting part 2 is formed in an L-shape in plan view. As shown in Fig. 17(b), the mounting part 2 may be formed in a triangular shape in plan view.

[0081] Although several embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. Furthermore, these embodiments can be implemented in various combinations as appropriate. Furthermore, the present invention can be implemented in various novel forms in addition to the several embodiments described above.
