Description

[Detailed description of the invention] [Technical field to which the invention belongs]

 The present invention is intended to reduce the number of machines and equipment such as computers and precision machines placed indoors and indoors, the mounting base for works of art installed indoors and indoors, and the mounting case containing works of art, etc. This is related to a seismic isolation table for mounting on products to protect against various vibrations such as generated.

[Prior art]

 Conventionally, for example, machines and equipment such as computers and precision machines are placed indoors and indoors, and various cultural heritage, valuable Buddha statues, sculptures, etc. There are a large number of mounting tables and mounting cases on which various types of art objects such as objects and valuable paintings are mounted. Conventionally, these mounting tables and mounting cases have been installed directly on the floor indoors and indoors, so when vibrations such as earthquakes occur, the mounting tables and mounting cases collapse and computers, artworks, etc. The mounted components will be damaged, damaged and suffer irreparable damage. In order to avoid such damages in advance, conventionally, a mounting table for storing a load and a mounting case have a strong structure. However, in this case, the cost is high, and in the case of such a structure, the mounting table and the mounting case are collapsed against a vibration such as a large earthquake. Therefore, conventionally, to avoid the above-mentioned inconveniences, an elastic body such as an oil damper or rubber is placed between the installation surface and the mounting table or mounting case under the mounting table to absorb vibrations due to shear deformation. There are seismic isolation devices and the like configured to be able to do so. In addition, a plurality of platforms with rollers interposed between them are arranged under the mounting platform, and the multiple platforms move back and forth and left and right in response to an earthquake. There are seismic isolation devices configured to be able to absorb.

[Problems to be solved by the invention]

 However, a seismic isolation system was constructed in which an elastic body such as an oil damper or rubber was placed between the installation surface and the mounting base or mounting case under the above-mentioned conventional mounting base to absorb vibrations due to shear deformation. It is often difficult for devices and the like to absorb vibrations generated by a large earthquake or the like only with such elastic bodies. In addition, in the case of a seismic isolation device in which a plurality of gantry with rollers are interposed under the above-mentioned conventional mounting gantry and the gantry moves forward, backward, left and right in response to an earthquake, Since each platform simply moves back and forth, left and right, the range within which each moving platform can be moved without falling off and out of each other is limited. Therefore, the place where this seismic isolation device is installed requires a considerably large space, and there is an inconvenience that it is impossible to apply this seismic isolation device to a very existing or off-the-shelf mounting base, mounting case, etc. . The present invention has been developed in view of the conventional circumstances described above, and its purpose is to absorb horizontal vibrations even in the case of various types of earthquakes and other vibrations, large or small. It is possible to prevent a situation in which a computer on a table placed on the floor, mechanical equipment such as precision equipment, various mounted items on a mounting table, various mounted items stored in a mounting case, etc. may fall down. At the same time, after the occurrence of an earthquake or other vibration, the mounting table can be smoothly and quickly returned to the original position, and the installation location can be set in a relatively small space. It is to provide a seismic isolation device that can be applied.

As shown in FIGS. 1 and 2, the seismic isolation device 1 includes a lower frame 10 disposed on a floor 2, an intermediate frame 20 disposed on the lower frame 10, and an intermediate frame 20. And an upper pedestal 40 disposed on the pedestal. A in FIG. 1 is a mounting case for storing works of art and the like, and the seismic isolation device 1 is used in a state as shown in FIG. 2, for example. The lower gantry 10 is a rectangular thin box having an opening 11 on the upper surface, and is provided with a shallow groove 12 facing upward. The intermediate frame 20 has openings 21 and 22 on the upper and lower surfaces, respectively, and has a rectangular thin box shape above and below the center plate 23, and faces upward and downward from the center plate 23. Shallow grooves 24 and 25 are provided, respectively, and the upper groove 24 is formed as an upper intermediate frame 26 and the lower groove 25 is formed as a lower intermediate frame 27. The upper gantry 40 is, for example, as shown in FIG. 2, formed in a rectangular thin box shape having an opening 41 on the lower surface, and is provided with a shallow groove 42 facing downward. On the upper frame 40, a machine such as a computer, a precision machine, or the like, or a work of art is mounted. As shown in FIGS. 1 and 3, the lower frame 10, the upper intermediate frame 26, the lower intermediate frame 27, and the upper frame 40 of the intermediate frame 20 are provided in respective frames whose grooves face each other. Each of the rail bodies 50 having a concave groove shape and an inverted concave groove shape is disposed at the left and right positions within the respective groove portions facing each other. That is, the left and right positions of the groove 12 of the lower gantry 10 and the left and right positions of the groove 25 of the lower middle pedestal 27 are provided with concave and inverted grooves at the left and right positions in the mutually opposing grooves. The body 50 is arranged. Also, as shown in FIGS. 1 and 3, the left and right positions of the groove 24 of the upper intermediate frame 26 and the left and right positions of the groove 42 of the upper frame 40 are different from the groove 12 and the lower intermediate portion of the lower frame 10. Each of the rail bodies 50 having a concave groove shape and a reverse concave groove shape is disposed at right and left positions in the mutually facing groove portions in a state of being orthogonal to and intersecting with each of the rail members 50 arranged in the groove portion 25 of the gantry 27. Accordingly, each rail body 50 disposed in the groove 24 of the upper middle base 26 and the groove 42 of the upper base 40, and each rail disposed in the groove 12 of the lower base 10 and the groove 25 of the lower middle base 27. The body 50 is arranged so as to cross at right angles. Between the rails 50, 50 arranged in the groove 12 of the lower frame 10 and the groove 25 of the lower intermediate frame 27, and in the groove 24 of the upper intermediate frame 26 and the groove 42 of the upper frame 40. Between each of the rail bodies 50, 50, an end face facing the opening 11 of the lower mount 10 and the opening 22 of the lower intermediate mount 27, and an opening 21 of the upper intermediate mount 26 and an opening 41 of the upper mount 40 are provided. The upper and lower rails 50 are sandwiched from above and below by respective rail surfaces 51 vertically opposed to the respective rail bodies 50 disposed on the respective platforms while providing gaps 81 with the opposing end surfaces. The intermediate bases 20 are individually movable horizontally in directions orthogonal to each other, and move on the rail surface 51 within a certain range within the length of each rail body 50 arranged on each of the bases. Transfers configured to be flexible Body 97, for example, comprises a roller body 60 having a respective roller 63 or the like as shown in the following Figure 10. The moving body 97 is sandwiched from above and below by rail surfaces 51 opposed to each other vertically above and below each rail body 50 disposed on each of the frames, and when a vibration such as an earthquake occurs, the lower frame 10 and the intermediate frame 20 are moved. Any configuration may be used as long as it is freely movable horizontally in directions orthogonal to each other, and is movable on the rail surface 51 within a certain range within the length of each of the rail bodies 50 arranged on each of the pedestals. The configuration is not particularly limited. For example, the moving body 97 may be configured by each roller body 60 as shown in FIG. The certain range within the length of each rail body 50 means a certain range within the length of each rail body 50, and as described later, for example, in the longitudinal direction of each rail body 50. When the vertical pieces 56 project from both ends, the moving body 97 can move on the rail surface 51 in each of the vertical pieces 56. Accordingly, the lower frame 10, the lower intermediate frame 27 of the intermediate frame 20, the upper intermediate frame 26 of the intermediate frame 20, and the upper frame 40 mount the moving body 97, for example, each roller body 60, in each frame. As shown by arrows in FIG. 1, FIG. 5, FIG. 6, and FIG. 9, when vibration such as an earthquake occurs, the lower mount 10 and the intermediate mount 20 are individually arranged. It is configured to be able to move horizontally while absorbing vibration in the overhang state freely in the front, rear, left and right directions perpendicular to each other, and is in a stacked state. Since the lower mount 10 and the intermediate mount 20 move horizontally in an overhang state freely freely in the front-rear, left-right, and right-and-left directions, respectively, this supports the upper mount 40 on which art works and the like are mounted. The lower part, which moves in all directions, absorbs vibrations and prevents the art work on the upper gantry 40 from collapsing. In addition, reference numerals 70 or 90 indicated by two-dot chain lines in FIG. 1 indicate the positions between the lower mount 10 and the lower intermediate mount 27 of the intermediate mount 20, and the upper intermediate mount 26 of the intermediate mount 20. A different embodiment from the later-described stopper body 90 or stopper body 70, which is arranged orthogonally to each rail body 50 between the respective gantry, between the respective rail bodies 50 arranged at the left and right positions between the upper gantry 40, respectively. It is a stopper body 70 in the form. In the embodiment of the present invention, the lower gantry 10 and the intermediate gantry 20 are configured to be able to move horizontally while absorbing vibration in the overhang state freely in the front, rear, left and right directions, respectively, at right angles to each other. Combined with a stopper body 70 which restricts each of the above-mentioned horizontally moving pedestals from falling off or falling out, the horizontal movement of the lower gantry 10 and the intermediate gantry 20 can be safely performed over a considerably wide range. Since it can be moved, the size of each stand can be made relatively small and compact, and the installation place of this equipment can be set in a relatively small space. For example, this equipment can be placed as it is inside an existing or ready-made mounting case A etc. And can be applied. The rail surface 51 on the upper surface of each of the rail bodies 50 vertically arranged in the respective grooves of the lower frame 10, the lower intermediate frame 27 of the intermediate frame 20, the upper intermediate frame 26 of the intermediate frame 20, and the upper frame 40 Each of the rails 50 may be implemented as a rail surface 51 in a horizontal state, and as shown in FIGS. 3, 4, 5, and 6, each rail 50 The rail surface 51 may be modified. That is, FIGS. 3, 4, 5, and 6 show the rail surface 51 of the rail body 50 in the groove 12 of the lower gantry 10 and the rail surface 51 of the rail body 50 in the groove 24 of the upper middle gantry 26. In addition, when viewed from the side, a state in which a curved portion 52 having a gentle inclination is formed is shown. The rail surface 51 of each rail body 50 disposed in each groove between the lower middle frame 27 and the upper frame 40 of the middle frame 20 is also provided on the rail surface 51 of the rail body 50 in the groove 12 of the lower frame 10. When viewed from the side such as the surface 51 and the rail surface 51 of the rail body 50 in the groove portion 24 of the upper intermediate frame 26, a curved portion 52 having a gentle inclination is formed and formed. Is also good. When the rail surface 51 of the rail body 50 in the groove 12 of the lower gantry 10 and the rail surface 51 of the rail body 50 in the groove 24 of the upper middle gantry 26 are formed by forming a loosely curved portion 52, The lower pedestal 10 and the intermediate pedestal 20 can be individually moved back and forth perpendicularly to each other. The horizontal movement in the left and right directions can be more smoothly performed, and the upper pedestal 40 can perform highly efficient vibration absorption. 10. It is possible to further speed up the return force of the respective intermediate mounts 20 to their original positions. The lower frame 10, the lower middle frame 27 of the middle frame 20, the upper middle frame 26 of the middle frame 20, and each end of each rail body 50 vertically arranged in each groove of the upper frame 40, As shown in FIG. 5, FIG. 6, etc., each vertical piece 56 for restricting the maximum horizontal movement range (maximum overhang position) of the lower gantry 10 and the middle gantry 20 is provided. . As shown in FIG. 4, when each moving platform reaches the maximum position of its movement, the moving body 97, for example, each roller 63, comes into contact with each vertical piece 56 and stops moving. Note that, instead of this, the vertical piece 56 may have the inner wall surface of each pedestal to perform the same function as the vertical piece 56. When the vertical pieces 56 are protruded from both ends of each rail body 50 in the longitudinal direction, as described above, the moving body 97, for example, the roller 63, moves the rails in the respective vertical pieces 56. It becomes movable on the surface 51. The left and right rail bodies 50 in the groove 42 of the upper gantry 40 and the left and right rail bodies 50 in the groove 25 of the lower middle gantry 27 of the middle gantry 20 face inward. Rollers 71 of a stopper body 70 to be described later are mounted at further inside positions of the respective rail surfaces 51. As a receiving body of the rollers 71, as shown in FIGS. 3 and 7, each stopper receiving surface 53 having an appropriate width is provided. The provided stopper receiver 54 is formed. Each stopper receiving surface 53 of the stopper receiving member 54 may be formed horizontally as shown in FIGS. 3 and 7, and has a bottom portion 55 when viewed from the side as shown in FIG. It may be formed as a V-shape or an arc shape having a gently inclined surface 53. When each stopper receiving surface 53 of the stopper receiving member 54 is formed in a V-shape or a circular arc shape having a gently inclined surface 53 having a bottom portion 55, the lower frame 10 and the intermediate frame 20 are formed. The horizontal movement in the front-rear and left-right directions, which are orthogonal to each other, can be further smoothly performed, and the vibration of the upper gantry 40 can be highly efficiently damped. Each movement of the lower gantry 10 and the middle gantry 20 is prevented while preventing the middle gantry 20 from falling off and coming off, and preventing the upper gantry 40 from falling off and coming off from the rail body 50 of the middle gantry 20. It is possible to more quickly return the gantry to its original position. When each stopper receiving surface 53 of the stopper receiving member 54 is formed in a V-shape or an arc shape having a gently inclined surface 53 having a bottom portion 55, as shown in FIG. 10. When the horizontal movement range of the intermediate unit base 20 reaches the maximum movement position (maximum overhang position) (in the state shown in FIG. 6), each roller 71 becomes the inclined surface 53 of the stopper receiving surface 53. At the highest position (the portion indicated by the broken line in FIG. 8), and the movable gantry (the lower gantry 10, the intermediate gantry 20) stops. When the roller 71 is located at the center as shown by the solid line in FIG. 8, the lower mount 10 and the intermediate mount 20 are in a state as shown in FIG. In the groove 12 of the lower frame 10 and the groove 24 of the upper intermediate frame 26 above the intermediate frame 20, the intermediate frame 20 is prevented from falling off the rail body 50 of the lower frame 10. In order to prevent the upper frame 40 from falling off and coming off from the rail body 50 of the intermediate frame 20, the left and right sides of the groove 12 of the lower frame 10 and the groove 24 of the upper intermediate frame 26 of the middle frame 20 are prevented. A stopper body 90 is provided between the rail bodies 50 so as to be orthogonal to each of the rail bodies 50. A reference numeral 90 indicated by a two-dot chain line in FIG. 3 denotes a stopper body disposed between the upper middle frame 26 and the upper frame 40 of the middle frame 20. The stopper body 90 has the same configuration as the stopper body 90 disposed between the lower frame 10 and the lower intermediate frame 27 of the intermediate frame 20, and is formed by the lower frame 10 and the lower intermediate frame 27 of the intermediate frame 20. It is arranged between the upper middle frame 26 and the upper frame 40 of the middle frame 20 orthogonally to the stopper body 90 arranged therebetween. As shown in FIG. 3, the stopper body 90 of the present embodiment has rollers 71 provided rotatably at both left and right ends, and two nuts 96 for supporting the concave holding frame 93 are attached to the lower part. It is fixed vertically in the groove 12 of the gantry 10 and in the groove 24 of the middle gantry 26 above the middle gantry 20. Reference numeral 91 in FIG. 3 denotes a nut that supports the holding frame 93 on the nut 96. Therefore, in this embodiment, the height of the holding frame 93 with respect to the nut 96 can be freely adjusted by the tightening state of the nut 91, whereby the stopper receiving surface 53 can be adjusted. Since the contact state of the rollers 71 can be adjusted, it is possible to freely adjust the horizontal movement of the lower gantry 10 and the intermediate gantry 20 in the front, rear, left and right directions, respectively, which are orthogonal to each other. The roller 71 of the stopper body 90 is not limited to the roller itself. In short, as long as the contact state of the stopper receiving surface 53 can be adjusted, the stopper receiving surface 53 may be configured as a simple bar. In this regard, the same applies to the rollers 71 of the stopper body 70 in a modified embodiment described later. When each stopper receiving surface 53 of the stopper receiving body 54 is formed horizontally as shown in FIG. 7, the horizontal movement range of the lower gantry 10 and the intermediate gantry 20, as shown in FIG. When the movement position reaches the maximum (maximum overhang position) (in the state of FIG. 6), each roller 71 is positioned at the highest portion of the inclined surface 53 of the stopper receiving surface 53 (see FIG. 7). As a result, the movable gantry (the lower gantry 10, the intermediate gantry 20) stops. When the roller 71 floats at the center as shown by the solid line in FIG. 7, the lower gantry 10 and the intermediate gantry 20 are in a state as shown in FIG. FIG. 4 shows a stopper body 70 according to a modified embodiment. The stopper body 70 has rotatable rollers 71 provided at both left and right ends of a concave holding frame 73, and the holding frame 73 is provided at the center position of the holding frame 73. A screw core 94 is vertically fixed in the groove 12 of the lower mount 10 and the groove 24 of the upper intermediate mount 26 above the intermediate mount 20, and a nut 92 is mounted on the screw core. In the case of the stopper body 70 of the modified embodiment, similarly to the case of the above-described stopper body 90, the stopper receiving surface 53 of the stopper receiver 54 is horizontal or horizontal as shown in FIGS. It is needless to say that the present invention can be applied to a V-shaped or arc-shaped member having a gently inclined surface 53 having a bottom portion 55. At the left and right positions of the holding frame 73, elastic bodies 78 such as springs 77, which urge upward and downward and exert an elastic action, are mounted around the respective screw core rods 76. The substrate 80 is fixed to the bottom of the groove 12 of the lower gantry 10 and the bottom of the groove 24 of the upper intermediate gantry 26 of the intermediate gantry 20 while having a gap 75 on the bottom surface where a spacer 74 can be mounted. A reference numeral 70 indicated by a two-dot chain line in FIG. 4 denotes a stopper body disposed between the upper middle frame 26 and the upper frame 40 of the middle frame 20. The stopper body 70 has the same configuration as the stopper body 70 disposed between the lower frame 10 and the lower intermediate frame 27 of the intermediate frame 20, and is formed by the lower frame 10 and the lower intermediate frame 27 of the intermediate frame 20. It is disposed between the upper intermediate frame 26 and the upper frame 40 above the intermediate frame 20 orthogonally to the stopper body 70 disposed therebetween. In FIG. 4, reference numeral 79 denotes a roller shaft of each roller 71, reference numeral 82 denotes a pressing plate disposed above an elastic body 78 such as a spring 77, and reference numeral 83 denotes a screw core rod 76 at the bottom of the groove 12 of the lower base 10, at an intermediate base 20 This is a screw head when it is fixed to the bottom of the groove 24 of the upper middle base 26. In this case, the left and right rollers 71 of the stopper body 70 are respectively connected to the left and right stopper receivers 54 in the groove 42 of the upper frame 40 and in the groove 25 of the lower intermediate frame 27 of the intermediate frame 20. When the lower frame 10 and the intermediate frame 20 move freely freely while absorbing vibrations in the front-rear, right-left and left-right directions, respectively, the lower frame 10 and the intermediate frame 20 are positioned on the stopper frame 53. It is designed to rotate. Therefore, in this embodiment, the spacer 74 can be mounted, and the strength of the tightened state of the elastic body 78 can be adjusted, and the contact state of the roller 71 with the stopper receiving surface 53 can be adjusted. 10. It is possible to freely adjust the attenuation in the front, rear, left and right directions that are orthogonal to each of the intermediate part mounts 20 individually. 7 and 8, the roller 71 can be freely changed and adjusted (the lower surface of the roller 71 can be brought into contact with the stopper receiving surface 53 while maintaining its strength or lifted. By doing so, it is possible to adjust the attenuation strength of each horizontal movement of the lower gantry 10 and the intermediate gantry 20. As shown in FIG. 10, for example, the roller body 60 is located at the upper and lower ends in the left and right vertical directions and has the horizontal axis members 61 fixed thereto, and each vertical axis member 62 arranged in a [] shape; Each roller 63 is provided at the right and left ends of each horizontal shaft member 61 so as to be rotatable vertically, and is rotatably horizontally rotatable at the upper and lower ends of each vertical member 62 located inside the rollers 63. And each roller 64 provided. The vertically rotatable rollers 63 of the horizontal shaft members 61 have upper and lower ends, respectively, of the lower frame 10, the upper intermediate frame 26, the lower intermediate frame 27, and the upper frame 40 of the intermediate frame 20. The lower frame 10 and the intermediate frame 20 move in separate horizontal directions while being held in contact with the respective rail surfaces 51 of the respective rail bodies 50 arranged in the respective grooves from above and below. At this time, each roller 63 rotates. The respective outer ends of the respective rollers 64 that are horizontally rotatable with respect to the respective vertical axis members 62 are arranged such that the outer ends of the respective rollers 64 that are horizontally opposed to the lower frame 10 and the upper intermediate frame 26 of the intermediate frame 20 are lower. It comes into contact with each vertical inner wall surface 58 of each rail body 50 arranged in each groove of the intermediate frame 27 and the upper frame 40, and in this state, the intermediate frame 20 and the upper frame 40 move individually in the horizontal direction. Then, each roller 64 guides the movement. As shown in FIGS. 5 and 6, the roller body 60 itself moves freely as the lower frame 10 and the intermediate frame 20 move individually in the horizontal direction. The seismic isolation device according to the present embodiment configured as described above has, for example, a device such as a computer, a precision machine or the like, or a work such as a work of art mounted on the upper pedestal 40. In the event of various vibrations such as earthquakes, the lower mount 10 and the intermediate mount 20 move horizontally while absorbing vibration in the overhang state freely freely in the front, rear, left and right directions, respectively. Since the configuration is such that a computer, a machine such as a precision machine or the like, and a mounted object on the upper gantry 40 can be prevented from being collapsed. Then, a loose curved portion 52 is formed on the rail surface 51 of the rail body 50 in the groove 12 of the lower gantry 10 and the rail surface 51 of the rail body 50 in the groove 24 of the upper middle gantry 26. In this case, the lower mount 10 and the intermediate mount 20 can be freely and horizontally moved in the front-rear direction and the left-right direction, respectively, respectively, and can be further smoothly moved. 10. It is possible to further quickly restore the intermediate frame 20 to its original position. In addition, since the lower frame 10 and the intermediate frame 20 move freely in an overhang state freely in the front-rear, left-right and right-right directions, respectively, the upper frame mounts cosmetics and the like. The lower portion supporting the upper frame 40 absorbs vibrations while moving in all directions to prevent the art work and the like on the upper frame 40 from collapsing. In addition, since each of the above-mentioned horizontally moving pedestals does not fall off or fall out, it is possible to move horizontally while absorbing vibrations in the overhang state freely freely in the front and rear and left and right directions that are orthogonal to each other. The horizontal movement of the lower frame 10 and the intermediate frame 20 can be safely moved to a considerably wide range in combination with the stopper body 70 that is regulated, so that the size of each frame is relatively small. Can be configured to extract, location of the device is also rather good in a relatively small space, for example the existing, can be applied as it is placed the device in the interior of such off-the-shelf mounting case A. Further, each stopper receiving surface 53 of each of the stopper receiving members 54 of the lower intermediate frame 27 of the intermediate frame 20 and the upper frame 40 is formed into a V-shape or a circle having a gently inclined inclined surface 53 having a bottom 55. When formed in an arc shape, the free horizontal movement of the lower frame 10 and the intermediate frame 20 in the front-rear and left-right directions, which are orthogonal to each other, is further smoothed, and the highly efficient vibration of the upper frame 40 is achieved. Damping can be performed, and the returning force of each of the movable gantry of the lower gantry 10 and the intermediate gantry 20 to the original position can be further accelerated. In addition, the high and low support positions of the holding frame 93 on the nut 96 of the stopper body 90 can be freely and easily adjusted by the tightening state of the nut 91. Since the contact state of the rollers 71 can be adjusted, it is possible to freely adjust the horizontal movement of the lower gantry 10 and the intermediate gantry 20 in the front, rear, left and right directions, respectively, which are orthogonal to each other. Further, in the stopper body 70 of the modified embodiment, the spacer 74 can be attached, and the strength of the tightened state of the elastic body 78 can be adjusted, whereby the contact state of the roller 71 with the rail surface 53 can be adjusted. Therefore, the lower pedestal 10 and the intermediate pedestal 20 can be adjusted freely in the front-rear, left-right and right-to-left directions, respectively.
