  Hereinafter, the pressing jig 1 according to the embodiment of the present invention will be described. FIG. 1 is an exploded perspective view showing the holding jig 1, and FIG. 2 is an assembled perspective view.

  The holding jig 1 is mainly composed of a base 3, an elevating plate 7, a lower fixing plate 9, an upper fixing plate 13, an elevating bolt 17, a push bolt 37, and the like. Each structure of the holding jig 1 only needs to have a certain degree of strength, and is made of, for example, steel. In the following description, the notch side (upper right direction in the figure) of the upper and lower fixing plates shown in FIGS. 1 and 2 is the front of the holding jig 1 and the opposite side (lower left direction in the figure) is the holding jig. 1 will be described as the rear.

  The base 3 is a reverse box-shaped member in which four sides of the plate-like member are bent downward. The base 3 is a member for fixing the pressing jig 1 to the floor. A hole 19 is provided at a position near the front end of the base 3 in the substantial center in the width direction. The hole 19 is a hole through which a lifting bolt 17 described later passes. Female screws 51 are provided on both sides of the hole 19.

  An arcuate groove 41 having an arcuate shape with the hole 19 as a substantially central point is provided behind the hole 19. The arc-shaped groove 41 is a groove that is recessed with respect to the periphery, and has a width that allows the end of a push bolt, which will be described later, to fit into the groove. On both sides of the base 3, long holes 5 are provided along the axial direction (front-rear direction). The long hole 5 is for inserting and fixing a fixing member such as an anchor or a bolt when the base 3 is fixed to the floor. By setting it as the long hole 5, the freedom degree of the installation position of a fixing member can be raised with respect to the axial direction of the base 3. FIG.

  A lifting bolt 17 is inserted into the hole 19 of the base 3 from below. Since the diameter of the hole 19 is larger than the diameter of the lifting bolt 17, the lifting bolt 17 can be rotated while being inserted into the hole 19. In a state in which the lifting bolt 17 is inserted from below the base 3, a stopper 31 is provided so as to cover the head of the lifting bolt 17. The retaining member 31 is formed by bending a plate-like member, and bolts 35 inserted into holes provided on both sides of the retaining member 31 are fixed to the female screw 51. That is, the retainer 31 is fixed to the base 3 by the bolt 35. The lifting bolts 17 are held by the stoppers 31 without falling from the base 3.

  A lifting plate 7 is provided above the base 3. The elevating plate 7 is a plate-like member and can be moved up and down with respect to the base 3. The elevating plate 7 is provided with a female screw 21 and a female screw 39 in the front-rear direction. The female screw 21 is a part to which the elevating bolt 17 is screwed. The female screw 39 is a part into which a push bolt 37 described later is screwed. The elevating bolt 17 is screwed with the female screw 21 and further protrudes upward from the elevating plate 7.

  A lower fixing plate 9 as a fixing member is provided on the elevating plate 7. The lower fixing portion plate 9 is a member having a substantially U-shaped cross-sectional shape in which both side portions of the plate-like member are bent downward.

  The lower fixing plate 9 has a step 12 that is inclined downward in front of the flat surface portion 10 a located on the base 3. In front of the step 12, a flat portion 10b having a surface substantially parallel to the flat portion 10a is formed. That is, the flat portion 10 b at the front end of the lower fixing plate 9 is positioned below the flat portion 10 a located on the base 3. The lift plate 7 is fitted between both side portions of the flat portion 10 a of the lower fixing member 9. In a state where the elevating plate 7 is fitted to the lower fixing plate 9, a slit 23 is provided in a portion of the lower fixing plate 9 corresponding to the female screws 21 and 39 of the elevating plate 7.

  The slit 23 has a width larger than the shaft diameters of the elevating bolt 17 and the push bolt 37, and the elevating bolt 17 and the push bolt 37 can be inserted therethrough. The slit 23 is provided to extend in the front-rear direction substantially at the center in the width direction of the lower fixing plate 9. The length of the slit 23 is longer than the distance between the female screw 21 and the female screw 39 by at least the depth of a notch 15 described later. That is, in a state where the elevating bolt 17 and the push bolt 37 are screwed to the female screw 21 and the female screw 39, at least the depth of the notch 15 can be slid.

  A female screw 49 is provided on the side of the slit 23. The female screw 49 is a part into which a slide restricting bolt 43 described later is screwed.

  The flat portion 10b is provided with a notch 11 that opens to the side. The notch 11 may be U-shaped, U-shaped, or any other shape. The shape of the notch will be described later.

  An upper fixing plate 13 is stacked above the lower fixing plate 9. The upper fixing plate 13 has a cross-sectional shape and an outer shape that are substantially the same as the lower fixing plate 9, and is slightly wider than the lower fixing plate 9. Therefore, the lower fixing plate 9 is fitted below the upper fixing plate 13.

  The upper fixing plate 13 is provided with a slit 25 at a position substantially corresponding to the slit 23 of the lower fixing plate 9. The slit 25 is provided to extend in the front-rear direction at approximately the center in the width direction of the upper fixing plate 13 and has substantially the same shape as the slit 23. A slit 45 is provided on a side of the slit 25 corresponding to the female screw 49 of the lower fixing plate 9. The slide restriction bolt 43 can be inserted into the slit 45, and the slide restriction bolt 45 is screwed with the female screw 49.

  In the vicinity of the front end portion of the upper fixing plate 13, a notch 15 that opens forward is provided. That is, the notch 15 opens in a direction substantially perpendicular to the notch 11. The shape of the notch will be described later.

  Note that the upper fixing plate 13 and the lower fixing plate 9 have substantially the same overall length, but with respect to the flat portion 10a of the lower fixing plate 9, the corresponding flat portion 10c of the upper fixing plate 13 (that is, above the base 3). The length of the flat part) is long. Therefore, the upper fixing plate 13 can slide backward relative to the lower fixing plate 9 by the difference in length between the flat portion 10c and the flat portion 10a. That is, the upper fixing plate 13 is slidable backward with respect to the lower fixing plate 9 by the length until the steps of the upper and lower fixing plates collide with each other.

  3 is a cross-sectional view taken along the line AA in FIG. 2, and is a cross-sectional view at a position where the lifting bolt 17 is provided. The base 3 is arranged on the floor 53 and fixed by a fixing member 55 inserted through the elongated hole 5. The elevating bolt 17 is inserted into the base 3 from below, and is prevented from dropping by the retainer 31. A washer 27 and a nut 29 are provided on the elevating bolt 17 that passes through the base 3, is screwed with the elevating plate 7, passes through the slits 23 and 25 of the upper and lower fixing plates, and protrudes above the upper fixing plate 13. It is done.

  That is, the elevating bolt 17 is screwed with the elevating plate 7, and the upper and lower fixing plates are sandwiched between the elevating plate 7, the nut 29, and the like. A groove 57 is provided at the tip of the elevating bolt 17, and the elevating plate 7 can be moved up and down with respect to the base 3 by rotating the groove 57 with a screwdriver or the like.

  4 is a cross-sectional view taken along the line BB of FIG. 2, and is a cross-sectional view at a position where the push bolt 37 is provided. The push bolt 37 penetrates the slits 25 and 23 from above the upper fixing plate 13, is screwed into the female screw 39 of the elevating plate 7, and further projects below the elevating plate 7. The front end of the push bolt 37 is located on an arcuate groove 41 provided on the base 3. The push bolt 37 moves up and down with respect to the lifting plate 7, and when the push bolt 37 is screwed downward, the tip of the push bolt 37 comes into contact with the bottom of the arc-shaped groove 41 and presses the base 3.

  Next, the shape of each notch part of the upper fixing plate 13 and the lower fixing plate 9 will be described. FIG. 5A is a plan view of the vicinity of the tip of the upper fixing plate 13. The upper fixing plate 13 has a notch 15 having an opening 57 on the front side. That is, the upper fixing plate 13 has a notch that opens in the sliding direction of the upper fixing plate 13.

  On the other hand, as shown in FIG. 5B, the lower fixing plate 9 has a notch 11 having an opening 59 on the side. That is, the lower fixing plate 9 has a notch that opens in a direction perpendicular to the sliding direction of the upper fixing plate 13 with respect to the lower fixing plate 9.

  FIG.5 (c) is a top view which shows the state which accumulated the upper and lower fixing plates. By overlapping the notches 11 and 15, the openings 57 and 59 are closed by the notch shape. Therefore, a closed annular fixing hole 61 is formed by overlapping the notches 11 and 15. The fixing hole 61 is determined by the size of the notches 11 and 15, but the length of the fixing hole 61 (the length in the left-right direction in the figure) can be changed by sliding the upper and lower fixing plates. .

  Next, the operation of the upper and lower fixing plates will be described. FIG. 6 is a plan view showing the operation of the upper and lower fixing plates. FIG. 6A is a diagram illustrating a state in which the upper fixing plate 13 is moved rearward with respect to the lower fixing plate 9. When the upper fixing plate 13 is slid rearward with the slide restricting bolt 43 removed, the steps of the fixing plates come into contact with each other (or the slits 23 and 25 come into contact with the lifting and lowering bolts 17 and 37 and are restricted. ) Slide until

  In this state, the notch 15 of the upper fixing plate 13 moves to the rear of the notch 11 of the lower fixing plate 9. Therefore, the notch 11 of the lower fixing plate 9 is exposed in front of the upper fixing plate 13. That is, the opening 59 is exposed.

  When the upper fixing plate 13 is slid forward from this state (in the direction of arrow C in the figure), the opening 59 is closed by the upper fixing plate 13 as shown in FIG. Therefore, the fixing hole 61 that does not open to the outside is formed.

  When the upper fixing plate 13 is slid until the lower fixing plate 9 and the upper fixing plate 13 are almost completely overlapped and the opening 59 is closed, the female screw 49 of the lower fixing plate 9 is exposed to the slit 45 of the upper fixing plate. To do. In this state, as shown in FIG. 6C, the slide restricting bolt 43 is screwed into the female screw 49. By attaching the slide restricting bolt 43, the upper fixing plate 13 is restricted from sliding backward. Even in this state, it is possible to slide the upper fixing plate 13 further forward. The size of the fixing hole 61 can be reduced by further sliding the upper fixing plate 13 forward (direction C in FIG. 6B) from the state of FIG.

  Next, functions of the lifting bolt 17 and the push bolt 37 will be described. FIG. 7 is a side view of the holding jig. As shown in FIG. 7A, the nut 29 and the push bolt 37 are loosened in a state where the upper and lower fixing plates are provided on the elevating plate 7 so as to overlap each other. Next, the lifting bolt 17 is rotated by the groove 57 of the lifting bolt 17 (in the direction of arrow D in the figure). As the elevating bolt 17 rotates, the elevating plate 7 screwed with the elevating bolt 17 moves up and down. Therefore, the upper and lower fixed plates on the elevating plate 7 move up and down in accordance with the vertical operation of the elevating plate 7 (in the direction of arrow E in the figure). That is, the height of the upper and lower fixing plates can be adjusted by rotating the lifting bolt 17.

  When the height of the upper and lower fixing plates is adjusted by the lifting bolt 17, the nut 39 is then tightened, and the upper and lower fixing plates are fixed in a state of being sandwiched between the lifting plate 7 and the nut 29.

  Further, in this state, the push bolt 37 is tightened downward (in the direction of arrow F in the figure). When the push bolt 37 is tightened downward, the tip of the push bolt 37 eventually comes into contact with the base 3 (the bottom of the arc-shaped groove 41) and is pressed downward by the push bolt 37 (in the direction of arrow G in the figure).

  When further screwed in a state where the tip of the push bolt 37 presses the base 3, the lifting plate 7 screwed with the push bolt 7 is lifted with respect to the base 3. Therefore, the rear end sides of the upper and lower fixing plates are lifted upward (in the direction of arrow H in the figure). At this time, since the height of the upper and lower fixing plates is fixed at the position of the lifting bolt 17, the upper and lower fixing plates rotate around the position of the lifting bolt 17. That is, the rear end of the upper and lower fixing plates is lifted, so that the tip moves downward (in the direction of arrow I in the figure). Therefore, by rotating the push bolt 37, the tip of the pressing jig 1 can be pressed downward.

  Next, a method for using the holding jig 1 will be described. 8-11 is a figure which shows the process of fixing an apparatus using the pressing jig 1. FIG.

  First, the slide restricting bolt 43 is removed, and the upper fixing plate 13 is slid rearward with the push bolt 37 and the nut 29 loosened to expose the opening 59 of the notch 11. From the opening 59, the shaft 65 of the leg 63 provided below the equipment 67 (FIG. 8B) is fitted. The leg part 63 is a leveler of the equipment 67, for example.

  As shown in FIG. 8 (b), when the shaft 65 is fitted into the opening 65, the height of the upper and lower fixing plates is adjusted with the lifting bolt 17 in advance according to the thickness of the leg portion 63. At this time, it is not necessary that the lower surface of the lower fixing plate 9 and the upper surface of the leg portion 63 are in contact with each other. The floor 53 on which the base 3 is installed may be a concrete floor or a free access floor panel. When the holding jig 1 is installed on the free access floor panel, the fixing member connected to the base 3 may be fixed to the concrete portion under the floor using a turnbuckle or the like.

  Next, as shown in FIG. 9A, the upper fixing plate 13 is slid forward. By sliding the upper fixing plate 13 forward, the opening 59 of the lower fixing plate 9 is closed. That is, the shaft 65 is disposed so as to penetrate the fixing hole 61. At this time, the sliding amount of the upper fixing plate 13 is changed according to the diameter of the shaft 65. That is, when the shaft 65 is thick, the upper fixing plate 13 is slid so as to be a fixing hole 61 through which the shaft 65 can penetrate. Further, when the shaft 65 is thin, the upper fixing plate 13 is further slid forward, and the fixing hole 61 is made small so that, for example, the leg portion 63 does not come out of the fixing hole 61.

  After adjusting the sliding amount of the upper fixing plate 13 and adjusting the size of the fixing hole 61 to the size of the leg portion 63 and the shaft 65, the nut 29 is tightened to fix the upper and lower fixing plates. At this time, by providing the slide restricting bolt 43, the nut 29 is loosened due to vibration or the like, and the upper fixing plate 9 slides to expose the opening 59, and the shaft 65 is fixed to the fixing hole 61 (notch 11). ) Can be prevented.

  Next, as shown to Fig.10 (a), a position is adjusted so that the base 3 can be fixed to a predetermined fixed position, and it fixes to a floor part. In a state where the push bolt 37 is loosened, the base 3 can be rotated at an arbitrary angle around the lifting bolt 17 with respect to the upper and lower fixing plates (elevating plate 7) (for example, in the direction of arrow K in the figure). .

  FIG. 10B and FIG. 10C are views showing the positional relationship between the base 3 and the tip of the push bolt 37 as the base 3 rotates. When the base 3 and the upper and lower fixing plates are directed in the same direction (for example, the state shown in FIG. 9B), the push bolt 37 (the tip thereof) is connected to the arc-shaped groove 41 as shown in FIG. Located in the approximate center.

  As shown in FIG. 10C, when the base 3 rotates around the hole 19 (the lifting bolt 17) (in the direction of arrow K in the figure), the push bolt 37 moves on the base 3 along the arc-shaped groove 41. To do. That is, even if the base 3 is rotated around the hole 19, the push bolt 37 is always accommodated in the arc-shaped groove 41.

  The base 3 is rotated to a position where it can be fixed to the floor, and the base 3 is fixed to the floor by the fixing member 55 from the long hole 5. Since the base 3 is rotatable and is fixed by the elongated hole 5, the degree of freedom of the fixing place is extremely high. For example, when installing on the free access floor, the base 3 can be easily fixed by adjusting to the position of the opening of the free access floor panel.

  Next, as shown in FIG. 11, the push bolt 37 is screwed (in the direction of arrow L in the drawing), and the upper and lower fixing plates are rotated around the fixing portion with the lifting bolt 17 (in the direction of arrow M in the drawing). The tips of the upper and lower fixing parts are pressed against the upper surface of the leg part 63 (in the direction of arrow N in the figure). In FIG. 11, the illustration of the fixing member 55 and the like is omitted. As described above, the holding jig 1 can be installed in the facility.

  As described above, according to the holding jig 1 according to the present embodiment, the upper fixing plate 13 and the lower fixing plate 9 are slidable with respect to each other, and are vertically directed to the tips of the upper and lower fixing portions. Since the notches 11 and 15 which open are provided, the opening is closed by the notches 11 and 15 by overlapping the upper and lower fixing plates, and the fixing hole 61 is formed. Therefore, the shaft 65 does not come out of the fixing hole 61.

  The size of the fixing hole 61 can be adjusted by the sliding amount of the upper fixing plate 13. Therefore, it is possible to cope with the sizes of the leg 63 and the shaft 65 having different sizes.

  Further, since the upper and lower fixing plates can be raised and lowered, the height of the upper and lower fixing plates can be easily adjusted according to the thickness of the leg portion 63 even when the thickness of the leg portion 63 is different. Therefore, it is possible to cope with the thickness of the leg portion 63 of devices having different sizes.

  Further, the tip portions of the upper and lower fixing plates are bent stepwise downward with respect to the position of the flat surface portion 10a (10c) positioned on the base of the fixing member, and a portion that presses the leg portion 63 (the flat surface portion 10b). ) Is positioned below the flat surface portion 10a, so that it is possible to cope with the leg portion 63 which is thinner than the thickness of the base 3.

  Further, since the slide amount between the upper fixing plate 13 and the lower fixing plate 9 can be restricted by the slide regulating bolt 43, the nut 29 and the like for fixing the upper fixing plate 13 are loosened after installation, and the upper fixing plate 13 is slid. This prevents the device pressing jig 1 from being detached from the device leg 63.

  In addition, since the upper and lower fixing plates can be rotated with respect to the base 3 in a stacked state, the installation direction of the base 3 is set with respect to the orientation of the upper and lower fixing plates that suppress the leg portion 63 of the device. Can be changed. Moreover, since the site | part which fixes the base 3 is the long hole 5, even when there is a restriction | limiting in the fixing position to a floor part, the position of the base 3 can be adjusted. For this reason, the freedom degree of the installation place of the holding jig 1 is high.

  In addition, since the arc-shaped groove 41 is provided in an arc shape with the hole 19 as the center, even when the base 3 is rotated with respect to the upper and lower fixing plates, the tip end of the push bolt 37 always fits in the arc-shaped groove 41. For this reason, when the push bolt 37 is tightened, the base 3 can always be pressed straight by the arc-shaped groove 41.

  Moreover, since the leg part 63 can be fixed only by adjustment of the raising / lowering bolt 17 and the push bolt 37, work is easy.

  As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs.
