[0010] Hereinafter, some embodiments of the present invention will be described with reference to the accompanying drawings. However, the dimensions, materials, shapes, relative arrangements, etc. of the components described as the embodiments or shown in the drawings are merely illustrative examples and are not intended to limit the scope of the present invention.

[0011] (Configuration of the support device for the instrument) Fig. 1 is a schematic diagram of a support device for instruments according to one embodiment. Fig. 2 is a view of the support device for instruments shown in Fig. 1 taken along the line AA. Fig. 3 is an enlarged view of the support device for instruments shown in Fig. 1. Figs. 1 to 3 show the support device 1 fixed to a grating 50.

[0012] 1 to 3 includes a plurality of main members 52 each extending in one direction in a plan view, and a plurality of auxiliary members 54 extending in a direction intersecting the extending direction of the main members 52 in a plan view (see FIG. 2). The main members 52 and the auxiliary members 54 may each be a flat plate-like member or a rod-like member. As shown in FIG. 2, the grating 50 has a plurality of openings 56 formed by the main members 52 and the auxiliary members 54.

[0013] 2, in a plan view, the pitch of the multiple main members 52 of the grating 50 (i.e., the pitch in the short-side direction of the grating 50) is smaller than the pitch of the multiple auxiliary members 54 (i.e., the pitch in the longitudinal direction of the grating 50). Therefore, the longitudinal direction of the opening 56 of the grating 50 is aligned with the extension direction of the main members 52, and the short-side direction of the opening 56 is aligned with the extension direction of the auxiliary members 54. In addition, in FIG. 2, the length of the opening 56 of the grating 50 in the short-side direction is indicated by Lb1, and the length of the opening 56 in the longitudinal direction is indicated by Lb2.

[0014] The support device 1 for an instrument shown in Figures 1 to 3 is a support device 1 for an instrument that is installed on a grating 50. The support device 1 shown in Figures 1 to 3 includes a base plate 2 provided on an upper surface 50a side of the grating 50, a support column 4 connected to the base plate 2, a locking member 8 provided on a lower surface 50b side of the grating 50, and a fixing device 10.

[0015] The base plate 2 is placed on the grating 50. As shown in Figures 1 and 2, the base plate 2 may have a rectangular flat plate shape.

[0016] The support pillars 4 are connected to the upper surface of the base plate 2, and are typically provided so as to extend in the up-down direction (vertical direction) when the support device 1 is installed on the grating 50.

[0017] The support column 4 is configured so that an instrument (not shown) can be attached thereto. Typically, the instrument is attached to the upper end of the support column 4. The support column 4 may also be configured so that a cover or the like for protecting the instrument can be attached thereto.

[0018] As shown in FIG. 1, the support device 1 may include reinforcing ribs 6 (not shown in FIGS. 2 and 3) for reinforcing the posts 4 on the base plate 2.

[0019] When the support device 1 is installed on the grating 50, the locking member 8 is arranged so as to straddle at least a pair of adjacent main members 52 among the multiple main members 52 on the underside 50b of the grating 50.

[0020] The fixing device 10 is configured to fix the locking member 8 to the base plate 2. The fixing device 10 shown in Figs. 1 to 3 includes a bolt 12 provided to penetrate the base plate 2, the grating 50, and the locking member 8, and a nut 14 screwed onto the bolt 12. The fixing device 10 may include a washer 16 (see Fig. 3) provided between the base plate 2 and the nut 14. The base plate 2 has a through hole (bolt hole) 3 through which the shaft of the bolt 12 is inserted. The locking member 8 has a through hole (bolt hole) 9 through which the shaft of the bolt 12 is inserted. The locking member 8 is fixed to the base plate 2 by screwing the bolt 12 into the nut 14 and tightening the nut 14.

[0021] According to the support device 1 of the above-described embodiment, the grating 50 is sandwiched between the base plate 2 provided on the upper surface 50a of the grating 50 and the locking member 8 provided on the lower surface 50b of the grating 50, and the locking member 8 can be fixed to the base plate 2 using a fixing device 10, so that the support device 1 including the support pillar 4 and base plate 2 can be easily fixed to the grating 50.

[0022] As shown in Figures 1 to 3, the locking member 8 may have a U-shape. The locking member 8 shown in Figures 1 to 3 has a flat plate portion 8a provided along the lower surface 50b of the grating 50, and a pair of protruding portions 8b connected to the flat plate portion 8a and protruding from the flat plate portion 8a toward the base plate 2. Note that, as shown in Figures 1 to 3, the locking member 8 may have a rectangular flat plate portion 8a and a pair of protruding portions 8b connected to both ends of the flat plate portion 8a in the longitudinal direction.

[0023] As described above, when the locking member 8 has a U-shape, even if the fastener 10 loosens, the rotation of the U-shaped locking member 8 is limited by the grating 50, so that further loosening of the fastener 10 can be suppressed. Alternatively, when the fastener 10 (e.g., the bolt 12 or the nut 14) is turned and tightened, the rotation of the U-shaped locking member 8 is limited by the grating 50, so that co-rotation of the locking member 8 can be suppressed. This makes it easier to install the support device 1 on the grating 50.

[0024] In some embodiments, the distance Lc (see FIG. 1) between the pair of protrusions 8b is greater than the short-side pitch of the grating 50. Alternatively, in some embodiments, when the support device 1 is installed on the grating 50, a gap G (see FIG. 3) is formed between the pair of protrusions 8b and the grating 50.

[0025] In this case, the distance Lc between a pair of protrusions 8b of the U-shaped locking member 8 is larger than the short-side pitch of the grating 50, or a gap G (see Figure 3) is formed between the pair of protrusions 8b and the grating 50, making it possible to apply the support device 1 to gratings having different pitches.

[0026] In some embodiments, the longitudinal size La2 of the locking member 8 (see FIG. 2) is shorter than the longitudinal length Lb2 of the opening 56 of the grating 50 and longer than the lateral length Lb1 of the opening 56. In FIG. 2, the lateral size of the locking member 8 is indicated by La1.

[0027] According to the above embodiment, since the longitudinal size La2 of the locking member 8 is shorter than the longitudinal length of the opening of the grating, when the support device 1 is installed, the locking member 8 can be moved smoothly from the upper surface 50a side of the grating 50 through the opening 56 of the grating 50 to the lower surface 50b side by aligning the longitudinal direction of the opening 56 of the grating 50. In addition, since the longitudinal size La2 of the locking member 8 is longer than the lateral length Lb1 of the opening 56 of the grating 50, the locking member 8 can be arranged on the lower surface 50b side of the grating 50 so that the longitudinal direction of the locking member 8 is aligned with the lateral direction of the opening 56 of the grating 50, so that the locking member 8 does not enter the opening 56 of the grating 50 due to interference between the locking member 8 and the grating 50, and the locking member 8 can be appropriately fixed to the base plate 2.

[0028] 1 to 3, in some embodiments, the fastener 10 is provided such that the nut 14 is located above the base plate 2. Moreover, the fastener 10 is provided such that the head of the bolt 12 is located below the grating 50.

[0029] According to the above-described embodiment, since the nut 14 is positioned above the base plate 2, an operator positioned above the base plate 2 can easily fix the locking member 8 to the base plate 2 by tightening the nut 14.

[0030] In some embodiments, the bolt holes (eg, the through holes 9 described above) provided in the locking member 8 may include circular holes.

[0031] Alternatively, although not specifically shown, in some embodiments, the bolt hole (for example, the above-mentioned through hole 9) provided in the locking member 8 may include an elongated hole extending along the longitudinal direction of the locking member 8. In this case, since the bolt hole (through hole 9) of the locking member 8 includes an elongated hole, it becomes easy to adjust the position of the bolt 12 relative to the locking member 8.

[0032] 1 to 3, in some embodiments, the base plate 2 may have a plurality of bolt holes (through holes 3) through which bolts 12 of fasteners 10 are respectively inserted, and a plurality of locking members 8 may be fixed to the base plate 2 by a plurality of fasteners 10 (bolts 12 and nuts 14) respectively provided corresponding to the plurality of bolt holes. In this case, each of the plurality of bolt holes (through holes 3) provided in the base plate 2 is provided at a position overlapping with an opening 56 of the grating 50 in a plan view.

[0033] According to the above-described embodiment, bolt holes (through holes 3) are provided in the base plate 2 at multiple positions that overlap with the openings 56 of the grating 50, and by installing multiple locking members 8 and fixing devices 10 corresponding to the multiple bolt holes (through holes 3), the support device 1 can be more stably fixed to the grating 50.

[0034] (Installation method of support device for measuring instruments) Next, a method for installing the support device 1 for an instrument according to some embodiments will be described with reference to Fig. 3 and Fig. 4A to Fig. 4C. Fig. 4A to Fig. 4C are diagrams for explaining a method for installing the support device 1 for an instrument according to some embodiments.

[0035] First, as shown in Fig. 4A, the fixing device 10 (bolt 12 and nut 14 in the illustrated example) and the locking member 8 are installed and hung from the base plate 2. At this time, the distance between the locking member 8 and the nut 14 in the axial direction of the bolt 12 is set to be larger than the thickness of the grating 50. In addition, the direction of the locking member 8 is set to a direction that allows it to pass through the opening 56 of the grating 50. For example, the direction of the locking member 8 is adjusted so that the longitudinal direction of the locking member 8 approximately coincides with the longitudinal direction of the opening 56.

[0036] Next, as shown in FIG. 4B, the fastener 10 and the locking member 8 are passed through the opening 56 of the grating 50, and a part of the fastener 10 (e.g., the head of the bolt 12) and the locking member 8 are positioned below the grating 50.

[0037] 4C, the locking member 8 is rotated (typically rotated about 90 degrees) in a plan view to adjust the orientation of the locking member 8 so that the longitudinal direction of the locking member 8 approximately coincides with the lateral direction of the opening 56. This adjustment of the orientation of the locking member 8 can be performed manually by a worker located above the grating 50.

[0038] Then, the nut 14 is tightened. As a result, the bolt 12 and the locking member 8 are raised to a position where the locking member 8 abuts against the grating 50, resulting in the state shown in Fig. 3, and the locking member 8 is fixed to the base plate 2. The work of tightening the nut 14 can be performed manually by a worker located above the grating 50.

[0039] In this manner, the support device 1 for an instrument according to some embodiments can be installed on the grating 50.

[0040] The contents described in each of the above embodiments can be understood, for example, as follows.

[0041] [1] At least one embodiment of the present invention relates to a support device for an instrument (1), A support device for an instrument installed on a grating (50), A base plate (2) provided on the upper surface (50a) side of the grating; a support (4) connected to the base plate and on which the meter is mounted; A locking member (8) provided on the lower surface (50b) side of the grating; a fastener (10) for fastening the engaging member to the base plate; Equipped with.

[0042] According to the configuration [1] above, the grating is sandwiched between a base plate provided on the upper side of the grating and a locking member provided on the lower side of the grating, and the locking member can be fixed to the base plate using a fixing device, so that the support device including the support pillar and base plate can be easily fixed to the grating.

[0043] [2] In some embodiments, in the configuration of [1] above, The locking member has a U-shape.

[0044] According to the configuration of [2] above, since the locking member has a U-shape, even if the fastener loosens, the rotation of the U-shaped locking member is limited by the grating, so that further loosening of the fastener can be suppressed. Alternatively, when the fastener (e.g., a bolt or nut) is turned and tightened, the rotation of the U-shaped locking member is limited by the grating, so that co-rotation of the locking member can be suppressed.

[0045] [3] In some embodiments, in the configuration of [2] above, The locking member is A flat plate portion (8a) provided along the lower surface of the grating; The base plate has a pair of protrusions (8b) connected to the flat plate and protruding from the flat plate toward the base plate.

[0046] According to the above configuration [3], the U-shaped locking member can be configured with a simple structure including a flat plate portion and a pair of protruding portions provided so as to protrude from the flat plate portion.

[0047] [4] In some embodiments, in the configuration of [3] above, The distance (Lc) between the pair of protrusions is greater than the short-side pitch of the grating.

[0048] According to the configuration [4] above, the distance between a pair of protrusions of the U-shaped locking member is greater than the pitch of the grating in the short direction, making it possible to apply the support device to gratings having different pitches.

[0049] [5] In some embodiments, in any one of the configurations [1] to [4] above, The longitudinal size (La2) of the engaging member is shorter than the longitudinal length (Lb2) of the opening (56) of the grating and longer than the lateral length (Lb1) of the opening.

[0050] According to the configuration of [5] above, since the longitudinal size of the locking member is shorter than the longitudinal length of the grating opening, when the support device is installed, the longitudinal direction of the locking member is aligned with the longitudinal direction of the grating opening, so that the locking member can be moved smoothly from the upper side of the grating through the grating opening to the lower side. Also, since the longitudinal size of the locking member is longer than the short-side length of the grating opening, the locking member can be arranged on the lower side of the grating so that the longitudinal direction of the locking member is aligned with the short-side direction of the grating opening, so that the locking member does not enter the grating opening due to interference between the locking member and the grating. This allows the locking member to be properly fixed to the base plate.

[0051] [6] In some embodiments, in any one of the configurations [1] to [5] above, The fixing device is A bolt (12) provided to penetrate the base plate, the grating, and the locking member; A nut (14) that is screwed onto the bolt; Includes.

[0052] According to the configuration [6] above, the locking member can be appropriately fixed to the base plate using a bolt that is arranged to penetrate the base plate, the grating, and the locking member, and a nut that is screwed onto the bolt.

[0053] [7] In some embodiments, in the configuration of [6] above, The fastener is mounted such that the nut is positioned above the base plate.

[0054] According to the configuration [7] above, the nut is positioned above the base plate, so that a worker positioned above the base plate can easily fix the locking member to the base plate by tightening the nut.

[0055] [8] In some embodiments, in the configuration of [6] or [7] above, The locking member has a bolt hole (through hole 9) through which the bolt is inserted, The bolt hole of the locking member includes an elongated hole extending along the longitudinal direction of the locking member.

[0056] According to the above configuration [8], since the bolt hole of the locking member includes an elongated hole, it is easy to adjust the position of the bolt relative to the locking member.

[0057] [9] In some embodiments, in any of the configurations [6] to [8] above, The base plate has a plurality of bolt holes (through holes 3) through which the bolts are respectively inserted, Each of the plurality of bolt holes is provided at a position overlapping with an opening of the grating in a plan view.

[0058] According to the configuration [9] above, bolt holes are provided in the base plate at multiple positions that overlap with the openings in the grating. By installing multiple locking members and fixing parts corresponding to the multiple bolt holes, the support device can be more stably fixed to the grating.

[0059] The above describes the embodiments of the present invention, but the present invention is not limited to the above-described embodiments, and also includes modifications to the above-described embodiments and appropriate combinations of these embodiments.

[0060] In this specification, expressions expressing relative or absolute configuration, such as "in a certain direction," "along a certain direction," "parallel," "orthogonal," "center," "concentric," or "coaxial," do not only strictly represent such a configuration, but also represent a state in which there is a relative displacement with a tolerance or an angle or distance to the extent that the same function is obtained. For example, expressions indicating that things are in an equal state, such as "identical," "equal," and "homogeneous," not only indicate a state of strict equality, but also indicate a state in which there is a tolerance or a difference to the extent that the same function is obtained. Furthermore, in this specification, expressions describing shapes such as a rectangular shape or a cylindrical shape do not only refer to shapes such as a rectangular shape or a cylindrical shape in the strict geometric sense, but also refer to shapes that include uneven portions, chamfered portions, etc., to the extent that the same effect can be obtained. In addition, in this specification, the expressions "comprise," "include," or "have" a certain element are not exclusive expressions that exclude the presence of other elements.
