Description

Technical Field

[0001] The present invention relates to a seismic isolation device that reduces vibration using an LM guide, and particularly to a seismic isolation device provided with an elastic rail that utilizes the principle of a pendulum to cause the LM guide to naturally return to the origin.

Background Art

[0002] Generally, when an earthquake occurs, vibrations are transmitted to structures such as buildings and equipment in the vertical or horizontal directions. The horizontal vibrations cause the structure to sway violently and twist.

[0003] If the scale of the vibrations transmitted at this time is large, it may partially damage the structure and reduce its stability, and in severe cases, it may even cause the structure to collapse.

[0004] Thus, various seismic isolation devices have been developed and used to protect structures and equipment from earthquakes.

[0005] On the other hand, an LM guide (Linear Motion Guide) is provided in a machine tool or the like having a form including a fixed body and a transfer body that linearly moves on the fixed body, and is a mechanical element that enables smooth relative linear motion.

[0006] Such an LM guide can be applied to a seismic isolation device and play a role in absorbing horizontal vibrations.

[0007] FIG. 1 is a diagram showing a seismic isolation device provided with an LM guide according to the prior art.

[0008] Conventional seismic isolation devices include an upper bracket 10 that supports the equipment to be seismically isolated from above; a lower bracket 20 having a shape corresponding to the upper bracket; and an LM guide consisting of an LM rail 30 provided across the diagonal lines between the inner surface of the upper bracket and the inner surface of the lower bracket, an LM block 40 that slides along the LM rail 30, and a retainer 50 that restricts steel balls to the LM block 40.

[0009] Furthermore, the LM block 40 connected to the LM rail 30 provided on the inner surface of the upper bracket 10 and the LM block 40 connected to the LM rail 30 provided on the inner surface of the lower bracket 20 can be connected to each other via a buffer member 70 in between.

[0010] Furthermore, by providing another vibration absorbing unit 80 along with the guide module between the upper bracket 10 and the lower bracket 20, both vertical and horizontal vibrations can be absorbed, preventing the upper bracket 10 and the lower bracket 20 from separating.

[0011] However, in conventional seismic isolation devices with the above configuration, the vibration absorption section 80 for forced return to the origin is made of a coil spring. However, coil springs are expensive and large, which limits the reduction in the overall dimensions of the seismic isolation device, and this results in various restrictions on where they can be used. In addition, if the coil spring is subjected to excessive deformation, permanent deformation occurs and the tension of the coil spring is lost. [Overview of the Initiative] [Problems that the invention aims to solve]

[0012] The present invention aims to solve the above-mentioned problems by providing an elastic rail 130 that provides elastic rebound force so that the guide block 120 can naturally return to its origin at the center, thereby reducing costs, significantly reducing the external dimensions of the product, and providing a seismic isolation device with high seismic isolation efficiency.

[0013] Furthermore, the present invention aims to solve the above-mentioned problems by providing a seismic isolation device that improves seismic isolation effect and strengthens durability by guiding the guide block so that it is forcibly returned to its origin at the center of the elastic rail by the elastic repulsive force of the elastic rail.

[0014] Furthermore, the present invention aims to provide a seismic isolation device that can reduce costs by eliminating the need for expensive coil springs, reduce the overall external dimensions of the product, and allow for diversification of installation locations.

[0015] Furthermore, the present invention aims to provide a seismic isolation device that can simplify the parts production process and improve productivity.

[0016] Furthermore, the present invention aims to provide a seismic isolation device that can improve durability and operational efficiency by adding an auxiliary elastic body.

[0017] Furthermore, the present invention aims to provide a seismic isolation device that can have a uniform elastic force by being installed using an "L" shaped elastic bracket.

[0018] Furthermore, the present invention aims to provide a seismic isolation device that is manufactured using a casting method (particularly waxing casting), thereby increasing economic efficiency by using only the minimum amount of raw materials, and facilitating and convenient production quality control.

[0029] In addition, a seismic isolation device according to another embodiment of the present invention includes a pendulum-type guide module 1000 and a cover plate 2000 attached to the pendulum-type guide module 1000.

[0052] [Example 1] As shown in Figures 1 to 4, the seismic isolation device according to Embodiment 1 of the present invention consists of a pendulum-type guide module 100, a cover plate 200, and a central module 300.

[0053] The pendulum-type guide module 100 is a device for linear reciprocating motion, and consists of two modules which are mounted symmetrically on the upper and lower parts of the elastic body, respectively, and are arranged to intersect with each other, so as to perform the function of reducing vibration by reciprocating motion in the horizontal direction.

[0054] More specifically, the pendulum-type guide module 100 consists of a guide rail 110, a guide block 120, an elastic rail 130, a fixed block 140, a support block 150, and a guide bearing 160.

[0055] The guide rail 110 is a component that guides the movement of the guide block 120, is formed in a straight line, and is fixed to the cover plate 200 in a diagonal direction.

[0056] The guide block 120 is mounted so as to slide along the guide rail 110.

[0057] Although not shown in the drawings, the structure between the guide rail 110 and the guide block 120 is configured to reduce vibration and friction during movement, with ball bearings inserted, similar to those in a typical LM guide.

[0058] On the other hand, the elastic rail 130 is fixed to the cover plate 200 and, in contact with the guide block 120, performs the function of guiding the guide block 120 to return to its origin at the center of the guide rail 110 by elastic force.

[0059] Specifically, the elastic rail 130 is formed in the shape of an elastic plate and is long enough to be parallel to the guide rail 110 along the direction of movement of the guide block 120.

[0060] Furthermore, the elastic rail 130 is formed to be inclined toward the cover plate 200 as it approaches the center, and the degree of inclination becomes gentler as it approaches the center.

[0061] In other words, the elastic rail 130 is formed to be concave in the direction of the cover plate 200, and its central part is formed to be nearly horizontal and gently curved.

[0062] Here, the center of the elastic rail 130 is positioned on the same line as the center of the guide rail 110.

[0063] Furthermore, the elastic rails 130 are positioned on both sides of the guide rails 110, and their ends are interconnected.

[0064] In other words, both ends of the elastic rail 130 are connected in a "U" shape and integrated together.

[0065] Furthermore, both ends of the elastic rail 130 are fixed to the cover plate 200 by the fixing block 140.

[0066] The fixing block 140 is formed in a hexahedral shape and is fixed to the cover plate 200.

[0067] Of course, depending on the circumstances, the fixing block 140 can also be manufactured as an integrated unit with the cover plate 200.

[0068] Furthermore, the fixing block 140 has a fixing inclined surface 141 formed on the surface that contacts the elastic rail 130, which is inclined toward the cover plate 200 as it moves toward the center of the elastic rail 130.

[0069] Therefore, the elastic rail 130 fixed to the fixing block 140 is tilted so that it is inclined toward the cover plate 200 as it moves toward the center.

[0070] Furthermore, the elastic rail 130 is positioned so as to be separated from the cover plate 200 by the height of the fixed block 140, thereby allowing the central part of the elastic rail 130 to bend and deform vertically.

[0071] Depending on the circumstances, the size of the fixing block 140 can be changed, and fixing bolts and backing blocks can be added to the fixing block 140 to prevent the guide block 120 from detaching from the guide rail 110.

[0072] Furthermore, the elastic rail 130 has a separate central section.

[0073] That is, as shown in Figure 3, the elastic rail 130 is arranged such that its central part is separated and the ends of the central part are isolated from each other for a certain period of time, allowing each to bend and deform independently.

[0074] On the other hand, the support block 150 is formed in a hexahedral shape and is positioned on both sides of the center of the guide rail 110, and is fixed to the cover plate 200.

[0075] Of course, depending on the circumstances, the support block 150 can also be manufactured as an integrated unit with the cover plate 200.

[0076] Such a support block 150 contacts and supports the elastic rail 130 when the central part of the elastic rail 130 is deformed by warping.

[0077] Furthermore, the support block 150 has support inclined surfaces 151 that are tilted in opposite directions at its center.

[0078] The support inclined surface 151 is formed to be inclined toward the cover plate 200 as it moves away from the center.

[0079] As shown in Figure 4, the aforementioned support inclined surface 151 supports the center of the elastic rail 130 and increases the elastic repulsive force of the elastic rail 130 when the guide block 120 moves to the end of the guide rail 110.

[0080] Of course, in some cases, the support block 150 may be made flat without the support inclined surface 151.

[0081] On the other hand, the guide bearings 160 are rotatably mounted on both sides of the guide block 120 and rotate in contact with the elastic rail 130 when the guide block 120 moves.

[0082] The guide bearing 160 transmits the elastic force of the elastic rail 130 to the guide block 120, minimizing friction with the elastic rail 130 and allowing it to operate naturally.

[0083] On the other hand, the cover plate 200 is made up of two pieces, similar to the pendulum-type guide module 100, and is arranged symmetrically above and below the central module 300, and each piece is connected to the pendulum-type guide module 100.

[0084] The central module 300 is a component that provides elastic force in the vertical direction and is made of vibration-damping rubber.

[0085] Of course, the central module 300 can be configured in various ways using soft plastic, spring suspension, or disc springs, etc.

[0086] The seismic isolation device according to Embodiment 1 of the present invention, having the above configuration, is supported such that the guide block 120 is forcibly returned to its origin at the center of the elastic rail 130 by the elastic repulsive force of the elastic rail 130. Furthermore, since there is no need to provide a separate coil spring, costs can be reduced, the outer shell dimensions can be decreased, and the installation location can be diversified. In addition, the device provides the effect of quickly and accurately returning the guide block to its origin at the center.

[0087] [Example 2] As shown in Figures 6 and 7, the seismic isolation device according to Embodiment 2 of the present invention has all the same components as in Embodiment 1 except for the pendulum-type guide module 100, so a description of that will be omitted, and the pendulum-type guide module 100 will be described in detail.

[0088] The pendulum-type guide module 100 according to Embodiment 2 consists of a guide rail 110, a guide block 120, an elastic rail 130, a fixed block 140, and a guide bearing 160.

[0089] The guide rail 110 is a component that guides the movement of the guide block 120, is formed in a straight line, and is fixed to the cover plate 200.

[0090] The guide block 120 is mounted so as to slide along the guide rail 110.

[0091] Although not shown in the drawings, a ball bearing is inserted between the guide rail 110 and the guide block 120, similar to a typical LM guide, to minimize vibration and friction during movement.

[0092] On the other hand, the elastic rail 130 is fixed to the cover plate 200 and is in contact with the guide block 120, guiding the guide block 120 to return to its origin at the center of the guide rail 110 by elastic force.

[0093] Specifically, the elastic rail 130 is formed in the shape of an elastic plate and is long enough to be parallel to the guide rail 110 along the direction of movement of the guide block 120.

[0094] Furthermore, the elastic rail 130 is formed to be inclined toward the cover plate 200 as it approaches the center, and the degree of inclination becomes gentler as it approaches the center.

[0095] In other words, the elastic rail 130 is formed to be concave in the direction of the cover plate 200, and its central part is formed to be nearly horizontal and gently curved.

[0096] Here, the center of the elastic rail 130 is positioned on the same line as the center of the guide rail 110.

[0097] These elastic rails 130 are arranged on both sides of the guide rail 110.

[0098] Furthermore, the elastic rail 130 is fixed at its center by a fixing block 140 so as to be separated from the cover plate 200 by a certain distance, and both ends are positioned in a free state so as to be able to bend up and down.

[0099] Here, the fixing block 140 is integrally formed with the center of the elastic rail 130 and is formed in a manner that protrudes from the center of the elastic rail 130 toward the cover plate 200.

[0100] Furthermore, anti-detachment portions 131 are provided protruding from both ends of the elastic rail 130.

[0101] The detachment prevention portion 131 is formed at both ends of the elastic rail 130 and is inclined so as to gradually increase in height in the direction opposite to the seismic isolation plate.

[0102] The aforementioned detachment prevention part 131 prevents the guide block 120 from detaching from the elastic rail 130.

[0103] Furthermore, the elastic rail 130 is manufactured with its central section separated, and can be joined by welding during assembly. This is to reduce manufacturing costs; while processing costs increase with longer lengths, cutting it in half allows for various manufacturing methods, such as casting, thus reducing manufacturing costs.

[0104] [Example 3] The seismic isolation device according to Embodiment 3 of the present invention is identical to that of Embodiment 2, except that it further includes an auxiliary elastic body 170 in addition to the pendulum-type guide module 100. Therefore, only the auxiliary elastic body 170 will be described in detail.

[0105] As shown in Figure 8, the auxiliary elastic body 170 is provided at both ends of the elastic rail 130 and elastically supports the elastic rail 130 in the direction opposite to the cover plate 200.

[0106] The auxiliary elastic body 170 is a leaf spring with a "V" shape, folded in the middle.

[0107] The auxiliary elastic body 170 is positioned at both ends of the elastic rail 130, with one end fixed to the cover plate 200 and the other end in contact with the elastic rail 130.

[0108] The auxiliary elastic body 170 serves to compensate for the fact that the elastic repulsive force weakens towards both ends of the elastic rail 130.

[0109] In this way, by providing the auxiliary elastic bodies 170 at both ends of the elastic rail 130, the overall elastic rebound force of the elastic rail 130 is improved, enabling rapid return to the origin.

[0110] [Example 4] As shown in Figure 9, the seismic isolation device according to Embodiment 4 of the present invention has all the same components as in Embodiment 1 except for the pendulum-type guide module 100, so only the pendulum-type guide module 100 will be described in detail.

[0111] The pendulum-type guide module 100 according to Embodiment 4 is the same as the pendulum-type guide module 100 according to Embodiment 1, but with an auxiliary elastic body 170 instead of the support block 150.

[0112] The auxiliary elastic body 170 is attached to the cover plate 200 and is a dome-shaped leaf spring that is curved in the direction of the elastic rail 130.

[0113] Such auxiliary elastic bodies 170 are provided one each on the left and right sides of the elastic rail 130, supporting the elastic rail 130 in the direction opposite to the cover plate 200.

[0114] [Example 5] As shown in Figure 10, the seismic isolation device according to Embodiment 5 of the present invention has all the same components as in Embodiment 1 except for the pendulum-type guide module 100, so only the pendulum-type guide module 100 will be described in detail.

[0115] The pendulum-type guide module 100 according to Embodiment 5 is composed of a guide rail 110, a guide block 120, an elastic rail 130, a fixed block 140, and a guide bearing 160.

[0116] The guide rail 110 is a component that guides the movement of the guide block 120, is formed in a straight line, and is fixed to the cover plate 200.

[0117] The guide block 120 is mounted so as to slide along the guide rail 110.

[0118] Although not shown in the drawings, a ball bearing is inserted between the guide rail 110 and the guide block 120, similar to a typical LM guide, to minimize vibration and friction during movement.

[0119] On the other hand, the elastic rail 130 is fixed to the cover plate 200 and is in contact with the guide block 120, guiding the guide block 120 to return to its origin at the center of the guide rail 110 by elastic force.

[0120] Specifically, the elastic rail 130 is formed in the shape of an elastic plate and is long enough to be parallel to the guide rail 110 along the direction of movement of the guide block 120.

[0121] Furthermore, the elastic rail 130 is fixed at both ends by the fixing block 140 so as to be separated from the cover plate 200 by a certain distance, and its central part is positioned in a free state so as to be able to deform by bending up and down.

[0122] Here, the fixing block 140 is integrally formed at both ends of the elastic rail 130 and has a shape that protrudes in the direction of the cover plate 200.

[0123] Furthermore, the elastic rail 130 is formed to be inclined toward the cover plate 200 as it approaches the center, and the degree of inclination becomes gentler as it approaches the center.

[0124] In other words, the elastic rail 130 is formed to be concave in the direction of the cover plate 200, and its central part is formed to be nearly horizontal and gently curved.

[0125] Here, the elastic rail 130 is positioned with its center aligned with the center of the guide rail 110, and is positioned on both sides of the guide rail 110.

[0126] Furthermore, the elastic rail 130 is formed such that its central part is separated and the ends of the central part are isolated from each other for a certain period of time, allowing each to bend and deform independently.

[0127] Here, the fixing block 140 is formed integrally with the elastic rail 130 and has a shape that protrudes in the direction of the cover plate 200.

[0128] Furthermore, an auxiliary elastic body 170 is provided in the center of the elastic rail 130.

[0129] The auxiliary elastic body 170 is provided at the center of the elastic rail 130 and elastically supports the elastic rail 130 in the direction opposite to the cover plate 200.

[0130] The auxiliary elastic body 170 is a leaf spring with a "V" shape, folded in the middle.

[0131] These auxiliary elastic bodies 170 are arranged symmetrically in the center of the elastic rail 130, with one end fixed to the cover plate 200 and the other end in contact with the elastic rail 130.

[0132] The auxiliary elastic body 170 serves to reinforce the elastic force in the central part of the elastic rail 130.

[0133] Therefore, by providing the auxiliary elastic bodies 170 at both ends of the elastic rail 130, the overall elastic rebound force of the elastic rail 130 is improved, enabling rapid return to the origin.

[0134] Since the guide bearing 160 is the same as that in Embodiment 1, a detailed explanation will be omitted.

[0135] [Example 6] As shown in Figure 11, the seismic isolation device according to Embodiment 6 of the present invention has all the same components as in Embodiment 1 except for the pendulum-type guide module 100, so only the pendulum-type guide module 100 will be described in detail.

[0136] The pendulum-type guide module 100 according to Embodiment 6 consists of a guide rail 110, a guide block 120, an elastic rail 130, and a guide bearing 160.

[0137] The guide rail 110 is a component that guides the movement of the guide block 120, is formed in a straight line, and is fixed to the cover plate 200.

[0138] The guide block 120 is mounted so as to slide along the guide rail 110.

[0139] Although not shown in the drawings, a ball bearing is inserted between the guide rail 110 and the guide block 120, similar to a typical LM guide, to minimize vibration and friction during movement.

[0140] On the other hand, the elastic rail 130 is fixed to the cover plate 200 and is in contact with the guide block 120, guiding the guide block 120 to return to its origin at the center of the guide rail 110 by elastic force.

[0141] Specifically, the elastic rail 130 is formed in the shape of an elastic plate and is long enough to be parallel to the guide rail 110 along the direction of movement of the guide block 120.

[0142] Furthermore, the elastic rail 130 is formed to be inclined toward the cover plate 200 as it approaches the center, and the degree of inclination becomes gentler as it approaches the center.

[0143] In other words, the elastic rail 130 is formed to be concave in the direction of the cover plate 200, and its central part is formed to be nearly horizontal and gently curved.

[0144] Furthermore, both ends of the elastic rail 130 are bent into a "U" shape to provide elasticity and fixed to the cover plate 200.

[0145] In other words, both ends of the elastic rail 130 are folded in a manner that is 180 degrees in the direction of the cover plate 200.

[0146] Both ends of the elastic rail 130 in this manner provide the elastic rail 130 with vertical elastic force.

[0147] Furthermore, the central part of the elastic rail 130 is positioned in a free state so that it can be deformed by bending up and down.

[0148] Furthermore, an auxiliary elastic body 170 is provided in the center of the elastic rail 130.

[0149] The auxiliary elastic body 170 is provided at the center of the elastic rail 130 and elastically supports the elastic rail 130 in the direction opposite to the cover plate 200.

[0150] The auxiliary elastic body 170 is a leaf spring with a "V" shape, folded in the middle.

[0151] These auxiliary elastic bodies 170 are arranged symmetrically in the center of the elastic rail 130, with one end fixed to the cover plate 200 and the other end in contact with the elastic rail 130.

[0152] Thus, the elastic rail 130 is formed by bending both ends to be elastic, and the auxiliary elastic body 170 is provided in the center, which increases the elastic force at both ends and in the center, reinforcing the elastic rebound force and providing the effect of returning to the origin quickly and accurately.

[0153] Since the guide bearing 160 is the same as that in Embodiment 1, a detailed explanation will be omitted.

[0154] [Example 7] As shown in Figures 12 to 16, the components of Embodiment 7 of the seismic isolation device according to the present invention are schematically composed of a pendulum-type guide module 1000, a cover plate 2000, and a central module 3000.

[0155] The components mentioned above can be explained in detail as follows:

[0156] The aforementioned pendulum-type guide module 1000 is a device for linear reciprocating motion, and consists of two modules which are mounted symmetrically on the upper and lower parts of the elastic body, respectively, and are arranged to intersect with each other, performing the function of reciprocating motion in the horizontal direction to reduce vibration.

[0157] Specifically, the pendulum-type guide module 1000 consists of a guide rail 1100, a guide block 1200, an elastic rail 1300, a fixed block 1400, and a guide bearing 1600.

[0158] The guide rail 1100 is a component that guides the movement of the guide block 1200, is formed in a straight line, and is fixed to the cover plate 2000 in a diagonal direction.

[0159] The guide block 1200 is mounted so as to slide along the guide rail 1100.

[0160] Although not shown in the drawings, a ball bearing is inserted between the guide rail 1100 and the guide block 1200, similar to a typical LM guide, to reduce vibration and friction during movement.

[0161] The elastic rail 1300 is fixed to the cover plate 2000 and, in contact with the guide block 1200, performs the function of guiding the guide block 1200 to return to its origin at the center of the guide rail 1100 by elastic force.

[0162] Specifically, the elastic rail 1300 is formed in the shape of an elastic plate and is long enough to be parallel to the guide rail 1100 along the direction of movement of the guide block 1200.

[0163] Furthermore, the elastic rail 1300 is formed to be horizontal or inclined towards the cover plate 2000 as it approaches the center, and if it is provided in an inclined manner, the degree of inclination becomes gentler as it approaches the center.

[0164] In other words, the elastic rail 1300 is formed to be concave in the direction of the cover plate 2000, and its central part is formed to be nearly horizontal and gently curved.

[0165] Here, the center of the elastic rail 1300 is positioned on the same line as the center of the guide rail 1100.

[0166] Furthermore, the elastic rails 1300 are arranged on both sides of the guide rails 1100 and have a rectangular shape with both ends interconnected in a "U" shape.

[0167] Furthermore, in order to overcome the problem that the elastic force increases as the guide block 1200 moves towards both ends, the elastic rail 1300 is formed with a structure in which the rail width narrows towards both ends. Therefore, the elastic rail 1300 is designed so that a uniform elastic force is applied to the guide block 1200.

[0168] Furthermore, the elastic rail 1300 includes a groove portion 1320 in the center formed by a circular groove in the direction of the cover plate 2000, and plate-shaped connecting portions 1360 at both ends.

[0169] The groove 1320 is formed to be slightly larger than the outer diameter of the guide bearing 1600, so that the guide bearing 1600 can be easily positioned in the groove 1320.

[0170] Therefore, the groove 1320 is positioned after the guide bearing 1600, which is coupled to the guide block 1200, moves to both ends of the elastic rail 1300 and then returns to its center.

[0171] The connecting portion 1360 has at least one through hole 1370 on its upper surface, and is connected to the fixing block 1400 through the through hole 1370 and fixed to the cover plate 2000.

[0172] Furthermore, the outer structure of the elastic rail 1300 is formed to be longer than the movement direction and distance (displacement) of the guide block 1200, based on a width that matches the width of the guide bearing 1600.

[0173] Furthermore, the elastic rail 1300 may further comprise a pair of grooves 1340 located on both sides of the groove 1320 and open inward.

[0174] Furthermore, the elastic rail 1300 may be further provided with detachment prevention sections (not shown, not named) at both ends, which are formed to prevent the guide block 1200 from detaching, and which are inclined so that their height gradually increases from the center outwards.

[0175] Furthermore, if the thickness of the elastic rail 1300 is constant, it can be formed in a structure where the width narrows towards both ends.

[0176] Furthermore, the elastic rail 1300 can be made of a variety of spring steels, including SPS1 to SPS9, SK5 and its series, various carbon tool steels, and other diverse metal materials.

[0177] The elastic rail 1300 formed in this manner has the effect of simplifying the parts production process, and thereby also has economic benefits.

[0178] The fixing block 1400 is formed in a hexahedral shape with at least one through hole and is fixed to the cover plate 2000.

[0179] The fixed block 1400 is formed in a hexahedral shape as one embodiment of the present invention, but is not limited thereto.

[0180] Furthermore, the fixing block 1400 can be manufactured as an integral part of the cover plate 2000.

[0181] The through-hole of the fixing block 1400 is connected to the through-hole 1370 of the elastic rail 1300 through fixing bolts.

[0182] Furthermore, the fixing block 1400 can, in some cases, be manufactured as an integral part of the cover plate 2000.

[0183] Furthermore, the fixing block 1400 has a fixing inclined surface 141 formed on the surface that contacts the elastic rail 1300, which is inclined toward the cover plate 2000 as it moves toward the center of the elastic rail 1300.

[0184] Accordingly, the elastic rail 1300 fixed to the fixing block 1400 is tilted so as it approaches the center, it tilts toward the cover plate 2000, and is positioned to be separated from the cover plate 2000 by the height of the fixing block 1400, thereby positioning the central part of the elastic rail 1300 to be deformable by bending up and down.

[0185] Furthermore, the size of the fixing block 1400 can be changed as needed, and fixing bolts and backing blocks can be added to the fixing block 1400 to prevent the guide block 1200 from detaching from the guide rail 1100.

[0186] On the other hand, as shown in Figure 6, the support block 1500, which is formed in a hexahedral shape, can be positioned between the guide rail 1100 and the cover plate 2000, or fixed to the cover plate 2000.

[0187] The support block 1500 is formed in a hexahedral shape as one embodiment of the present invention, but is not limited thereto.

[0188] Furthermore, the support block 1500 can, in some cases, be manufactured as an integrated unit with the cover plate 2000.

[0189] The support block 1500 is provided with a support inclined surface 151 formed on one surface, so that the height of the elastic rail 1300 can be adjusted.

[0190] Furthermore, the support block 1500 may, in some cases, be made flat without the support inclined surface 151.

[0191] On the other hand, the guide bearing 1600 is formed in the shape of a disc with a through hole in the center and is rotatably mounted on both sides of the guide block 1200, and rotates in contact with the elastic rail 1300 when the guide block 1200 moves.

[0192] The guide bearing 1600 transmits the elastic force of the elastic rail 1300 to the guide block 1200, minimizing friction with the elastic rail 1300 and allowing it to operate naturally.

[0193] The cover plate 2000 consists of two pieces, similar to the pendulum-type guide module 1000, and is arranged symmetrically above and below the central module 3000, with each piece being connected to the pendulum-type guide module 1000.

[0194] The central module 3000 is a component that provides elastic force in the vertical direction and is made of vibration-damping rubber.

[0195] Furthermore, the central module 3000 can be configured in various ways using soft plastic, spring suspension, or disc springs, etc.

[0196] In the seismic isolation device according to Embodiment 7 of the present invention, which has the configuration described above, the guide block 1200 is supported such that it is forcibly restored to its origin at the center of the elastic rail 1300 by the elastic repulsive force of the elastic rail 1300.

[0197] Furthermore, since there is no need to provide a separate coil spring, costs can be reduced, the outer shell dimensions can be decreased, and the installation location can be diversified.

[0198] Furthermore, this provides the effect of enabling the guide block to quickly and accurately return to its origin at the center.

[0199] [Example 8] As shown in Figures 17 and 18, Embodiment 8 of the seismic isolation device according to the present invention is identical to Embodiment 7 in all other respects, except that it further includes an auxiliary elastic body 1700 in the pendulum-type guide module 1000. Therefore, only the auxiliary elastic body 1700 will be described in detail.

[0200] The auxiliary elastic body 1700 is formed of a leaf spring having at least one through hole and is provided at both ends of the elastic rail 1300 to elastically support the elastic rail 1300 in the opposite direction to the cover plate 2000.

[0201] Specifically, the auxiliary elastic body 1700 is positioned at both ends of the elastic rail 1300, with one end fixed to the cover plate 2000 and the other end in contact with the elastic rail 1300.

[0202] The through-holes in the auxiliary elastic body 1700 are connected to the through-holes 1370 in the elastic rail 1300 and the through-holes in the fixing block 1400, and to the fixing bolts.

[0203] Such auxiliary elastic body 1700 serves to compensate for the fact that the elastic repulsive force weakens towards both ends of the elastic rail 1300.

[0204] Specifically, as shown in Figure 18, when the guide block 1200 moves to both ends of the elastic rail 1300 due to vibration, the guide bearing 1600 of the guide block 1200 puts a large stress on the elastic rail 1300, and also puts a large stress on the fixing bolts that secure the elastic rail 1300.

[0205] At this time, the auxiliary elastic bodies 1700 located at both ends of the elastic rail 1300 reduce the stress applied to the fixing bolts, causing a gentle "elastic warp" to occur in the elastic rail 1300, thereby improving the overall elastic rebound force of the elastic rail 1300, enabling rapid return to the origin, and thus increasing the durability and operational efficiency of the elastic rail 1300.

[0206] [Example 9] As shown in Figures 19 and 20, Embodiment 9 of the seismic isolation device according to the present invention is identical to Embodiment 7 in all other respects, except that the elastic rail 1300 of the pendulum-type guide module 1000 further includes an auxiliary rail 1800 and a clamp 1890. Therefore, only the auxiliary rail 1800 and clamp 1890 will be described in detail.

[0207] The auxiliary rail 1800 is fixed to the elastic rail 1300 through at least one clamp 1890, is located between the elastic rail 1300 and the cover plate 2000, and expands and contracts depending on the position of the guide block 1200 to support the elastic rail 1300.

[0208] Specifically, the auxiliary rail 1800 is formed in the form of an elastic plate with a groove 1820 in the center, and is formed to be long so as to be parallel to the guide rail 1100 and the elastic rail 1300 along the direction of movement of the guide block 1200.

[0209] The groove 1820 is formed to a size corresponding to the size of the groove 1320 of the elastic rail 1300.

[0210] Furthermore, the auxiliary rail 1800 is formed to be inclined toward the cover plate 2000 as it approaches the center, and the degree of inclination becomes gentler as it approaches the center.

[0211] In other words, the auxiliary rail 1800 is formed to be concave in the direction of the cover plate 2000, and its central part is formed to be nearly horizontal and gently curved.

[0212] The clamp 1890 is formed in a "C" shape and connects the elastic rail 1300 and the auxiliary rail 1800 to each other, and is positioned between the auxiliary rail 1800 and the cover plate 2000.

[0213] In one embodiment of the present invention, the auxiliary rails 1800 are arranged on both sides of the elastic rail 1300, but one or more may be installed depending on the design structure.

[0214] Furthermore, the auxiliary rail 1800 may be further provided with a through hole 1830 in the center of the groove 1820, and the elastic rail 1300 may also have a through hole 1330 formed in the center of the groove 1320, allowing the auxiliary rail 1800 and the elastic rail 1300 to be connected by fixing bolts.

[0215] In this case, the configuration of the elastic rail 1300 is the same as that of the elastic rail 1300 in the first embodiment of the present invention, so a detailed explanation will be omitted.

[0216] However, the elastic rail 1300 may be formed not only in a way that the rail width narrows towards both ends, but also in a way that the rail width is constant.

[0217] Therefore, the auxiliary rail 1800 and the elastic rail 1300 can be connected even more strongly.

[0218] [Example 10] As shown in Figures 21 to 25, Embodiment 10 of the seismic isolation device according to the present invention is identical to Embodiment 7 except that the form of the elastic rail 1300 of the pendulum-type guide module 1000 is modified, an elastic bracket 1900 is further included in the elastic rail 1300, and the elastic bracket 1900 is connected to the cover plate 2000. Therefore, only the elastic rail 1300, the elastic bracket 1900, and the cover plate 2000 will be described in detail.

[0219] The elastic rail 1300 is fixed to the cover plate 2000 and, in contact with the guide block 1200, performs the function of guiding the guide block 1200 to return to its origin at the center of the guide rail 1100 by elastic force.

[0220] Specifically, the elastic rail 1300 is formed in the shape of an elastic plate and is long enough to be parallel to the guide rail 1100 along the direction of movement of the guide block 1200.

[0221] Furthermore, the elastic rail 1300 is formed to be inclined toward the cover plate 2000 as it approaches the center, and the degree of inclination becomes gentler as it approaches the center.

[0222] Furthermore, the elastic rail 1300 can be formed horizontally.

[0223] In other words, the elastic rail 1300 is formed to be concave in the direction of the cover plate 2000, and its central part is formed to be nearly horizontal and gently curved.

[0224] Here, the center of the elastic rail 1300 is positioned on the same line as the center of the guide rail 1100.

[0225] Furthermore, the elastic rail 1300 is formed with a thicker thickness in the center and a thinner thickness at both ends than in the center.

[0226] Furthermore, the elastic rails 1300 are arranged on both sides of the guide rails 1100 and have a rectangular shape with both ends interconnected in a "U" shape.

[0227] Furthermore, in order to overcome the problem that the elastic force increases as the guide block 1200 moves towards both ends, the elastic rail 1300 is formed with a structure in which the rail width narrows towards both ends. Therefore, the elastic rail 1300 is designed so that a uniform elastic force is applied to the guide block 1200.

[0228] Furthermore, the elastic rail 1300 includes a groove portion 1320 formed in the center in the direction of the cover plate 2000 as a circular groove, plate-shaped connecting portions 1360 located at both ends, and a rectangular parallelepiped-shaped second connecting portion 1380 located on one surface of the connecting portion 1360 in the direction of the cover plate 2000.

[0229] The groove 1320 is formed to be slightly larger than the outer diameter of the guide bearing 1600, so that the guide bearing 1600 can be easily positioned in the groove 1320.

[0230] Therefore, the groove 1320 is positioned after the guide bearing 1600, which is coupled to the guide block 1200, moves to both ends of the elastic rail 1300 and then returns to its center.

[0231] The second connecting portion 1380 is provided with at least one through hole 1370 on its side surface, and is connected to the elastic bracket 1900 through the through hole 1370 and fixed to the cover plate 2000.

[0232] Furthermore, the elastic rail 1300 may further comprise a pair of grooves 1340 located on both sides of the groove 1320 and open inward.

[0233] Furthermore, the elastic rail 1300 can be made of a variety of spring steels.

[0234] Furthermore, the elastic rail 1300 is manufactured by a casting method (particularly waxing casting).

[0235] This solves the disadvantages of cutting a carbon steel sheet of a certain standard using a laser or water jet, which results in increased costs due to the large area of ​​the hollow section in the center of the elastic rail 1300, the difficulty in designing a complex shape where the width of the elastic rail 1300 varies depending on the position to provide various elastic repulsive forces depending on the operating position of the guide block 1200, and the fact that the maximum width of the elastic rail 1300 used to cut the sheet occupies more space than necessary.

[0236] When the elastic rail 1300 is produced by casting (especially waxing casting), the aforementioned problems are solved, and the width of the elastic rail 1300 is manufactured to be constant while using only the minimum amount of raw materials by casting molds. Furthermore, the design of the elastic rebound force at different positions can be made relatively easily by adjusting the thickness of the elastic rail 1300, and the mold production method has many advantages in other aspects of production quality control.

[0237] Therefore, the elastic rail 1300 formed in this manner has both the effect of simplifying the parts production process and economic benefits.

[0238] The elastic bracket 1900 is formed in the shape of an "L"-shaped plate with elastic repulsive force, and has at least one or more elastic rail coupling holes 1920 on one side and at least one or more cover plate coupling holes 1940 on the other side.

[0239] The elastic rail coupling hole 1920 is connected to the through hole 1370 of the elastic rail 1300 through a fixing bolt.

[0240] The cover plate connecting hole 1940 is connected to the cover plate 2000 through fixing bolts.

[0241] Since the elastic bracket 1900 formed in this manner possesses elastic repulsive force, it is possible to design it so that the guide block 1200 located on the upper part of the elastic rail 1300 has a uniform elastic force regardless of its position.

[0242] Furthermore, while the material of the elastic bracket 1900 can be diverse, including metal, plastic, and rubber, it is particularly effective to use high-carbon steel sheets that have been laser or waterjet cut and then heat-treated.

[0243] The cover plate 2000 consists of two pieces, similar to the pendulum-type guide module 1000, and is arranged symmetrically above and below the central module 3000, with each piece connected to the pendulum-type guide module 1000.

[0244] As shown in Figures 24 and 25, the cover plate 2000 has numerous through holes 2020 that allow an elastic bracket 1900 to be fitted inside and connected to numerous fixing bolts.

[0245] Furthermore, the numerous through holes 2020 may be formed to a size corresponding to the elastic bracket 1900, allowing it to be fitted and connected to numerous fixing bolts.

[0246] In the fourth embodiment of the present invention formed in this manner, after the numerous elastic brackets 1900 are fitted into the through holes 2020 of the cover plate 2000, the elastic brackets 1900 and the cover plate 2000 are joined together with numerous fixing bolts, and the elastic brackets 1900 and the elastic rail 1300 are joined together with numerous fixing bolts, thereby assembling the cover plate 2000, the elastic brackets 1900, and the pendulum-type guide module 1000.

[0247] As a result, as shown in Figure 23, in Embodiment 10 of the present invention, the elastic rail 1300 has a uniform elastic force regardless of the position of the guide block 1200 located on the upper part of the elastic rail 1300, through the elastic bracket 1900 which has an "L" shaped elastic rebound force.

[0248] [Example 11] As shown in Figures 26 and 27, Embodiment 11 of the seismic isolation device according to the present invention is identical to Embodiment 7 in all other components except for the guide block 1200 of the pendulum-type guide module 1000. Therefore, a detailed explanation of the guide block 1200 will be omitted, and only the guide block 1200 will be described in detail.

[0249] The guide block 1200 is mounted so as to slide along the guide rail 1100.

[0250] Although not shown in the drawings, a ball bearing is inserted between the guide rail 1100 and the guide block 1200, similar to a typical LM guide, to reduce vibration and friction during movement.

[0251] Furthermore, the guide block 1200 is further formed by having a "U" shaped block frame 1250 on the outside opposite to the side that connects to the guide rail 1100.

[0252] The guide block 1200 and the block frame 1250 are joined together through a number of bolts, as shown in Figures 26 to 27.

[0253] The block frame 1250 is provided with a pair of guide bearing coupling portions 1260 at both ends.

[0254] The guide bearing coupling portion 1260 has a through hole in the center and can be connected to the guide bearing 1600 by passing a bolt through it.

[0255] The bolts for the aforementioned connection may, but are not limited to, shoulder bolts.

[0256] The guide bearing 1600 is located between the pair of guide bearing couplings 1260.

[0257] The guide block 1200 of Embodiment 11 of the present invention, formed in this manner, can be formed into a guide block 1200 having a pendulum structure by simply fabricating and adding a block frame 1250 to a general guide block 1200.

[0258] [Example 12] As shown in Figure 28, Embodiment 12 of the seismic isolation device according to the present invention is identical to Embodiment 7 in all other respects, except that the pendulum-type guide module 1000 further includes a "U"-shaped elastic bracket 1900. Therefore, only the elastic bracket 1900 will be described in detail.

[0259] The elastic bracket 1900 is positioned between the elastic rail 1300 and the cover plate 2000, and the guide blocks 1200 at both ends of the elastic rail 1300 support the elastic rail 1300 when it moves.

[0260] The elastic bracket 1900 is formed in a U-shape, having an elastic repulsive force, and one of its two sides, which are bent or machine-cut to connect the central portion, has at least one elastic rail coupling hole 1920, while the other side has at least one cover plate coupling hole 1940.

[0261] The elastic rail coupling hole 1920 is connected to the through hole 1370 of the elastic rail 1300 through a fixing bolt.

[0262] The cover plate connecting hole 1940 is connected to the cover plate 2000 through fixing bolts.

[0263] Since the elastic bracket 1900 formed in this manner possesses elastic repulsive force, it is possible to design it so that the guide block 1200 located on the upper part of the elastic rail 1300 has a uniform elastic force regardless of its position.

[0264] Furthermore, while the material of the elastic bracket 1900 can be diverse, including metal, plastic, and rubber, it is particularly effective to use high-carbon steel sheets that have been laser or waterjet cut and then heat-treated.

[0265] Example 12 of the present invention formed as described above positions the multiple elastic brackets 1900 between the cover plate 2000 and the elastic rail 1300, and combines and forms them with the cover plate 2000 and the elastic rail 1300 through a number of fixing bolts, so that the cover plate 2000, the elastic brackets 1900, and the pendulum-type guide module 1000 can be assembled. Thereby, when the guide blocks 1200 move at both ends of the elastic rail 1300, the elastic rail 1300 can be supported. [[ID=Q1]] [[ID=Q2]]

[0266] [[ID=Q3]] [[ID=Q4]][Example 13][[ID=Q5]] [[ID=Q6]]As shown in FIGS. 29 to 31, Example 13 of the seismic isolation device according to the present invention is the same in all respects except that the form of the elastic rail 1300 of the pendulum-type guide module 1000 in Example 7 is changed. Therefore, only the elastic rail 1300 will be described in detail. [[ID=Q7]] [[ID=Q8]]

[0267] [[ID=Q9]] [[ID=Q10]]The elastic rail 1300 is fixed to the cover plate 2000, and functions to guide the guide block 1200 to return to the origin at the center of the guide rail 1100 by elastic force when contacting the guide block 1200. [[ID=Q11]] [[ID=Q12]]

[0268] [[ID=Q13]] [[ID=Q14]]Specifically, the elastic rail 1300 is formed in a plate shape with elasticity, and is formed long so as to be parallel to the guide rail 1100 along the moving direction of the guide block 1200. [[ID=Q15]] [[ID=Q16]]

[0269] [[ID=Q17]] [[ID=Q18]]In addition, the elastic rail 1300 is formed to be inclined in the direction of the cover plate 2000 toward the center, and the inclination becomes gentler toward the center. [[ID=Q19]] [[ID=Q20]]

[0270] [[ID=Q21]] [[ID=Q22]]In addition, the elastic rail 1300 may be formed horizontally. [[ID=Q23]] [[ID=Q24]]

[0271] [[ID=Q25]] [[ID=Q26]]That is, the elastic rail 1300 is formed to be concave in the direction of the cover plate 2000, and the center is formed to be approximately horizontal and gentle. [[ID=Q27]] [[ID=Q28]]

[0272] [[ID=Q29]] Here, the central portion of the elastic rail 1300 is arranged on the same line as the central portion of the guide rail 1100.

[0273] Further, the elastic rails 1300 are respectively arranged on both sides of the guide rail 1100 and have a rectangular shape with both ends interconnected in a "U" shape.

[0274] In addition, in order to overcome the problem that the elastic force of the elastic rail 1300 increases as the guide block 1200 moves to both ends, the elastic rail 1300 is formed in a structure where the rail width becomes narrower towards both ends. Therefore, the elastic rail 1300 is designed such that a uniform elastic force is applied to the guide block 1200.

[0275] However, the elastic rail 1300 may be formed not only in a structure where the rail width becomes narrower towards both ends but also in a form where the rail width is constant depending on the case.

[0276] In addition, the elastic rail 1300 includes a groove portion 1320 formed in a circular groove in the direction of the cover plate 2000 at the center and coupling portions 1360 formed in a "C" - shaped plate form at both ends.

[0277] The groove portion 1320 is formed to be slightly larger than the outer diameter of the guide bearing 1600 so that the guide bearing 1600 can be easily positioned in the groove portion 1320.

[0278] Therefore, the guide bearing 1600 coupled to the guide block 1200 returns to the center and is positioned after moving to both ends of the elastic rail 1300.

[0279] The coupling portion 1360 is connected to the elastic rail 1300 and has at least one through - hole 1370 in a portion protruding in the direction of the cover plate 2000.

[0280] The through - hole 1370 is fixed to the fixed block 1400 or the cover plate 2000 by being connected through a fixing bolt.

[0281] Furthermore, the through-hole 1370 can be fixedly connected to the auxiliary elastic body 1700 by a connection using a fixing bolt.

[0282] Furthermore, the outer structure of the elastic rail 1300 is formed to be longer than the movement direction and distance (displacement) of the guide block 1200, based on a width that matches the width of the guide bearing 1600.

[0283] Furthermore, the elastic rail 1300 may further comprise a pair of grooves 1340 located on both sides of the groove 1320 and open inward.

[0284] Furthermore, the elastic rail 1300 may be further provided with detachment prevention sections (not shown, not named) at both ends, which are formed to prevent the guide block 1200 from detaching, and which are inclined so that their height gradually increases from the center outwards.

[0285] Furthermore, if the thickness of the elastic rail 1300 is constant, it can be formed in a structure where the width narrows towards both ends.

[0286] Furthermore, the elastic rail 1300 can be made of a variety of spring steels, including SPS1 to SPS9, SK5 and its series, various carbon tool steels, and other diverse metal materials.

[0287] In this embodiment 13 of the present invention, the guide blocks 1200 at both ends of the elastic rail 1300 can support the elastic rail 1300 through the U-shaped joint 1360 when it moves. Furthermore, this has a remarkable effect from the viewpoint of cost reduction.

[0288] In the seventh to thirteenth embodiments of the seismic isolation device of the present invention, the elastic rail 1300 is formed with a structure in which the rail width narrows towards both ends in order to overcome the problem that the elastic force increases as the guide block 1200 moves to both ends. However, it may be formed into a variety of structures, including a form in which the rail width is constant.

[0289] Accordingly, the seventh to thirteenth embodiments of the seismic isolation device of the present invention provide the effect of improving seismic isolation and enhancing durability.

[0290] In the above, the configuration and operation of the seismic isolation device according to the present invention have been shown in detail with drawings, but this is merely an explanation using examples, and various changes and modifications are possible within the scope that does not deviate from the technical concept of the present invention.
