Description

  The present invention relates to an impact-resistant support device for reducing shocks and vibrations to various devices and controlling the vibrations so that vibrations caused by earthquakes and the like do not act on devices and structures.

  Conventionally, anti-shock measures in various fields (for example, to mitigate shocks and vibrations for stable operation of various devices, and to suppress vibrations such as earthquakes from acting on devices and structures) In this specification and claims, “impact” includes “vibration”).

  For example, electronic devices (supported bodies) provided in ships, vehicles, factories, etc. (supported bodies) are supported by impact-resistant support means so that vibrations and impacts are not directly transmitted from surrounding structures (support bodies), Conversely, power equipment and the like (supported body) are supported by impact-resistant support means so that their own vibrations and impacts are not directly transmitted to surrounding structures (supports).

  In addition, depending on the structure (supported body), various shock-resistant support means are used to suppress the structure so that the structure will not be damaged greatly away from the base part (support) due to a large earthquake. ing.

  As such an impact-resistant support means, the electronic device, the power device, etc., and the structure (hereinafter collectively referred to as “supported body”) are surrounded by an elastic structure, a base part, etc. ( In the following, elastic (impact) support means for supporting these with a generic term "support" is employed in many places.

For example, as a conventional technique related to such elastic support, for example, a gel-like cushioning material such as silicon or urethane that absorbs an impact by compression when receiving an impact, and an elastic structure of a leaf spring structure that absorbs the impact by elastic deformation The elastic structure, which is configured to support the built-in device with the body and has a predetermined gap with the built-in device, comes into contact with the built-in device when an impact exceeding a predetermined value is applied to the built-in device. There is an impact resistant device for a removable storage device that absorbs the impact by deforming it (see, for example, Patent Document 1).
JP 2002-367361 A (second page, FIG. 1)

  However, since the invention described in Patent Document 1 has a structure in which the periphery of the built-in device is supported by the buffer material, the built-in device is supported by the surrounding housing like the removable storage device described in the document. However, it cannot be applied to equipment that does not have a housing around the built-in device. In addition, in the case of a large supported body, it is difficult to stably support the surroundings.

  In addition, in this configuration, compressive stress and tensile stress act on the buffer material around the built-in device, so that there is a possibility of peeling from the surrounding configuration depending on the material of the buffer material.

  Accordingly, the present invention provides an impact-resistant support device that can stably support a supported body such as a device or structure that requires impact resistance with a support such as a base. For the purpose.

In order to achieve the above object, an impact resistant support device according to the present invention is provided with a support leg that is fixed to one of a support or a supported body, and the support leg is positioned between the support and the supported body. An impact support member formed of a high-attenuation material of ether-based polyurethane is provided on the support side and the supported side of the holding member, and both of the support members provided on the support side and the supported side of the holding member are provided. On the side of the impact support member opposite to the holding member, a concave surface that is inclined or curved so as to open a gap with the support or supported body toward the substantially central portion of the impact support member is formed. An impact support receiver is provided for supporting the impact support member provided on the support side and the supported side without contacting the holding member in contact with the concave surface of the support surface, and the support leg is one of the support and the supported side. in fixed state, position on the opposite to the fixed side of the support leg To the shock supporting receiving and the the contact surface with the shock supporting member detachably configured, the rigid hollow intermediate portion shock support member than the hardness of the shock supporting member provided in a central portion of said shock support member, said The impact support receiver is connected by a connecting member through a hollow portion of the intermediate impact support member, and the anti-fixed side of the support leg of the impact support receiver is fixed to the support body or the supported body. . According to such a configuration, the shock support members provided on the support body side and the supported body side of the holding member provided on the support leg can support the vibration and shock between the support body and the supported body. Can be stable. In addition, the direction in which the shock support member is compressed and the width direction in which the concave surface is received by the inclined surfaces that are inclined or curved formed on the impact support members provided on both sides of the holding member. Thus, the impact can be stably reduced and supported. In addition, since this support is made with an impact support member made of a high-damping material of ether polyurethane, vibration and impact can be supported with high attenuation even when a large load is applied, and extremely stable vibration And shock can be reduced.

Moreover, since the load acting on the width direction by the concave surface which is inclined or curved toward the substantially center line of the width direction before Ki衝 hammer support member can be received by the entire circumference, the direction of compressing the shock supporting member It is possible to provide support that relaxes vibrations and shocks by receiving the load acting on the load and the load acting from all directions in the width direction of the impact support member.

  The present invention has the following effects by the means described above.

  It is possible to stably support the supported body by attenuating vibration and impact between the support body and the supported body in the direction in which the impact support member is compressed and the width direction received by the concave surface of the impact support member. Therefore, it is possible to provide an impact-resistant support device that can stably reduce vibrations and impacts generated on the support and the support.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 is an exploded perspective view of an impact resistant support device showing a first embodiment of the present invention, FIG. 2 is a longitudinal sectional view of the impact resistant support device, FIG. 3 is a plan view of the impact resistant support device, and FIG. FIG. 3 is a side view of the impact resistant support device. In the following description, the case where the support leg of the impact resistant support device is fixed to the support side will be described.

  As shown in the figure, the impact resistant support device 20 is connected by a holding member 2 between support legs 1 (fixed to the support body 200 in the figure) that are fixed to one of the support body 200 or the supported body 201, and these support legs. 1 and the holding member 2 are formed in an integrated horse shape. The support leg 1 is integrally formed with a mounting portion 3 for fixing to the support body 200 or the supported body 201, and the mounting portion 3 is provided with a fixing hole 4. In FIG. 2, the attachment portion 3 is fixed to the support body 200 with bolts 21. These are made of a hard material such as metal. The holding member 2 is provided substantially parallel to the attachment surface of the attachment portion 3, and a through hole 5 is provided substantially at the center.

  Further, impact support members 6 and 7 are provided on the support member side (lower side in the figure) and the supported body side (upper side in the figure) of the holding member 2. As the impact support members 6 and 7, an ether-based polyurethane material or a gel material made mainly of silicon is used. In particular, a highly attenuating material (for example, a viscoelastic polymer compound) made of ether polyurethane is preferable. In this embodiment, impact support members 6 and 7 are provided on both sides of the holding member 2.

  As such impact support members 6 and 7, a high damping material having a damping ratio in the range of 40% to 80% is preferable. As a damping ratio of the high damping material, for example, a supported body 201 having a predetermined weight (for example, a heavy object having a weight of about 200 kg) is supported on a test table (support 200) by an impact-resistant support device 20, and the test table. Attenuation calculated from values obtained by reading an acceleration sensor in three directions of X, Y, and Z acting on the supported body 201 by allowing a 180 kg weight to fall freely on the (support 200) from a height of 150 cm. It is determined by the ratio. As the impact acceleration, for example, according to a fifth embodiment described later, about 4500G can be reduced to about 15G. G is the gravitational acceleration. In addition, it is possible to reduce both the vertical direction Z and the horizontal directions X and Y.

  The impact support members 6, 7 are formed with flat surfaces on the side in contact with the holding member 2, and concave surfaces 8, 9 on the side opposite to the holding member. In this embodiment, the inclined surfaces 8 and 9 (hereinafter referred to as “inclined surfaces”) are directed toward substantially the center line in the width direction of the impact support members 6 and 7 (virtual line in the direction orthogonal to the paper surface). It is formed by two opposing concave surfaces that are recessed. Bolt holes 10 and 11 are formed through substantially the center portions of the impact support members 6 and 7 formed in this way.

  In this embodiment, the support legs 1 that are in contact with the outer surfaces of the impact support members 6 and 7 are formed at substantially the same height as the thickness of the impact support members 6 and 7 (vertical height in the figure). The supporting members 6 and 7 are prevented from shifting in the width direction so as to receive a load. The height of the support leg 1 may be set according to the physical properties of the impact support members 6 and 7, the amount by which the supported body 201 is displaced, and the like.

  In this embodiment, inclined surfaces 8 and 9 are formed on both of the impact support members 6 and 7 provided on both surfaces of the holding member 2. The inclined surfaces 8 and 9 may be formed only on one of the impact support members 6 (7) on the support side or the supported side, depending on use conditions or the like.

  Further, as described above, the hollow disk-shaped intermediate impact support member 12 is provided in the through hole 5 provided in the holding member 2. The intermediate portion impact support member 12 has an outer shape that is substantially the same as the diameter of the through-hole 5 and is substantially the same thickness as the holding member 2, and is provided with a bolt hole 13 at the center. The hardness of the intermediate impact support member 12 may be the same as or different from that of the impact support members 6 and 7, but if a material harder than the impact support members 6 and 7 is used, the inclination of the bolt 16 described later can be suppressed. This is preferable.

  In a state where the intermediate impact support member 12 is provided in the through hole 5 of the holding member 2, impact support members 6 and 7 are provided on the support side and the supported side of the holding member 2. 14 and 15 are fixed with bolts 16. The impact support receiver 15 on the lower side of the figure is formed in a mountain shape such that the holding member 2 side (inner side) is along the inclined surface 9 of the impact support member 7, and the anti-holding member side (outer side) is substantially parallel to the holding member 2. It is formed on a flat surface. A plate portion 17 into which the head of the bolt 16 fits is formed at the center portion on the side opposite to the holding member, and a through hole 18 is formed at the center toward the holding member side. The impact support receiver 14 on the upper side of the figure is formed in a mountain shape such that the holding member side (inner side) is along the inclined surface 8 of the impact support member 6, and the anti-holding member side (outer side) is substantially parallel to the holding member 2. It is formed in such a plane. A bolt hole 19 into which a screw portion of the bolt 16 inserted from the lower impact support 15 is screwed is formed in the center portion.

  When the bolt 16 is inserted from the lower impact support receiver 15 and screwed into the bolt hole 19 of the upper impact support receiver 14, the attachment of the impact support members 6 and 7 is completed. In the state of FIG. 2, the support leg 1 is fixed to the support body 200 with the bolt 21, the upper impact support receiver 14 is fixed to the supported body 201 with the bolt 23, and the impact-resistant support device 20 is in a predetermined position. It is in the state of being arranged. Reference numeral 22 denotes a tapped hole.

  Furthermore, the impact support members 6 and 7 may be pre-compressed by the impact support receivers 14 and 15 so as to apply a predetermined load in advance. In this case, if the load applied in advance is within the range of the maximum load acting on the impact support members 6 and 7, the range in which the impact support members 6 and 7 are deformed is compressed even if the load acts on the impact resistant support device 20. It can be a deformation in a pre-compressed range between the state and the uncompressed state. As a result, a tensile load is not applied to the impact support members 6, 7, and only the compression load is always used, so that the displacement, separation, and crack between the impact support members 6, 7 and the impact support receivers 14, 15 are achieved. Etc. can be prevented.

  The amount (initial displacement amount) for pre-compressing the impact support members 6 and 7 can be adjusted by tightening the bolts 16, and is optimal by setting the pre-compression amount optimal for the mass of the supported body 201 to be supported. Attenuation effect, force, and transmission rate of mutation can be obtained. The pre-compression amount can be adjusted by adjusting the tightening force of the bolt 16 in accordance with the physical properties of the impact support members 6 and 7.

  FIG. 5 is a front view showing an example of a state where the impact resistant support device shown in FIG. 1 is used, and FIG. 6 is a side view showing an example of a state where the impact resistant support device is used. In the drawing, a rectangular supported body 201 having a certain amount of weight (for example, a heavy object of about 200 kg in which precision instruments are unitized) is taken as an example.

  In the case of the impact resistant support device 20 according to the first embodiment, since the two inclined surfaces 8 and 9 are formed on the impact supporting members 6 and 7, the impact provided so as to be in contact with the inclined surfaces 8 and 9. Loads from the support receivers 14 and 15 can be received by the two inclined surfaces 8 and 9. Therefore, according to the impact resistant support device 20, the compression direction in which the impact supporting members 6 and 7 are pressed against the holding member 2 and the width direction in which the inclined surfaces 8 and 9 of the impact supporting members 6 and 7 are formed. It is possible to support loads acting on the The load supported by the inclined surfaces 8 and 9 of the impact support members 6 and 7 is received by the support legs 1.

  In the case of the impact resistant support device 20 of this embodiment, as shown in FIGS. 5 and 6, the impact resistant support device 20 provided on the lower surface so as to mainly support the own weight of the supported body 201 is provided on the impact support members 6 and 7. When the inclined surfaces 8 and 9 are provided so as to be continuous, the impact-resistant supporting device is provided on the side surface of the supported body 201 so that the direction of the surface intersecting the inclined surfaces 8 and 9 of the impact supporting members 6 and 7 can be supported. 20 is provided. The arrangement of these impact-resistant support devices 20 is set according to the load acting on the supported body 201 and the magnitude of the impact.

  Even when the load acting on the impact support members 6 and 7 of the impact resistant support device 20 is large, the bolt 16 contacts the holding member 2 by the intermediate impact support member 12 provided in the through hole 5 of the holding member 2. Never do.

  Further, the arrangement of the impact resistant support device 20 shown in FIGS. 5 and 6 is an example, and the impact resistant support device 20 provided on the lower surface of the supported body 201 is alternately arranged so that the inclined surfaces 8 and 9 cross each other. If arranged, it is possible to support only one surface, and other arrangements may be used, and the arrangement of the impact-resistant support device 20 may be determined in accordance with the direction and size of the load.

  Therefore, according to such an impact-resistant support device 20, vibrations and impacts generated on the supported body 201 and vibrations and impacts from the support body 200 are attenuated by the impact support members 6 and 7, and the support body 200 or the supported body. Since it is transmitted to the support 201, vibrations and impacts are reduced by the impact support members 6 and 7, and transmission of vibrations and impacts between the support 200 and the supported body 201 can be greatly reduced. it can.

  In addition, the disposition of the impact-resistant support device 20 on the supported body 201 acts on at least one surface (the bottom surface in the case of one surface) from three directions including the front-rear direction, the left-right direction, and the up-down direction of the supported body 201. If arranged so as to mitigate the impact, it is possible to effectively attenuate the impact and vibration from the three directions (X, Y, Z) on the supported body 201. What is necessary is just to determine the surface in which this impact-resistant support apparatus 20 is provided according to the support method etc. of the to-be-supported body 201. FIG.

  7 is a longitudinal sectional view of an impact resistant support device showing a second embodiment of the present invention, FIG. 8 is a plan view of the impact resistant support device, and FIG. 9 is a side view of the impact resistant support device. In the second embodiment, the impact absorbing member and the support leg are different from the first embodiment described above. In addition, the same structure as 1st Embodiment mentioned above is attached | subjected and the code | symbol which added 30 is attached | subjected and demonstrated.

  As shown in FIG. 8, the shock-resistant support device 50 has the impact support members 36 and 37 formed in a substantially square shape in plan view, and the holding member 32 that supports the impact support members 36 and 37 is also substantially square. Is formed. A side wall 55 having the same height as the support leg 31 is provided on the surface of the holding member 32 where the support leg 31 is not provided. The side wall 55 and the support leg 31 form a space in which the substantially square impact support members 36 and 37 are provided.

  As shown in FIG. 7, also in the case of the second embodiment, the support leg 31 and the side wall 55 that are in contact with the outer surfaces of the impact support members 36 and 37 are approximately the thickness of the impact support members 36 and 37 (the vertical direction in the figure). The impact support members 36 and 37 are prevented from shifting in the width direction so as to receive a load.

  As shown in these drawings, in the second embodiment, attachment portions 33 for fixing the support legs 31 to the support body 200 or the supported body 201 are provided around the attachment portions 33. A fixing hole 34 is provided in the inner wall. The attachment portion 33 is formed integrally with a support leg 31 and a holding member 32. These are made of a hard material such as metal. Further, the holding member 32 is provided substantially parallel to the mounting portion 33, and a through hole 35 is provided in the substantially center of the holding member 32.

  The impact support members 36 and 37 in the second embodiment are the same as those in the first embodiment described above in the longitudinal section shown in FIG. 7, but as shown in FIG. 8, the inclined surface 38 is concave toward the center. , 39 (shown by broken lines) are formed on four sides. That is, the four inclined surfaces 38 and 39 are formed so that the anti-holding member side (upper surface) of the impact support members 36 and 37 is recessed in a quadrangular pyramid shape. Through holes 40 and 41 are provided at the center of the impact support members 36 and 37. The impact support members 36 and 37 are provided on the support side and the supported side of the holding member 32. These impact support members 36 and 37 are fixed by connecting impact support receivers 44 and 45 formed in a quadrangular pyramid shape with bolts 46 facing each other. The quadrangular pyramid portions of the impact support receivers 44 and 45 are formed in a shape matching the quadrangular pyramid inclined surfaces 38 and 39 of the impact support members 36 and 37.

  According to the shock resistant support device 50 of the second embodiment configured as described above, the four inclined surfaces 38 and 39 are formed on the impact support members 36 and 37. Loads from the impact support receivers 44 and 45 provided so as to contact each other can be received by these inclined surfaces 38 and 39. Therefore, according to the impact resistant support device 50, the compression direction (Z direction) for pressing the impact supporting members 36, 37 against the holding member 32 and the inclined surfaces 38, 39 of the impact supporting members 36, 37 are formed. It is possible to support a load acting in the width direction (X, Y direction).

  In the case of the impact resistant support device 50 of this embodiment, the loads acting in the full width direction of the impact support members 36 and 37 can be supported by the inclined surfaces 38 and 39 formed in a quadrangular pyramid shape. Compared with the first embodiment, the selection range for the support method of the support 201 is increased. Also in this embodiment, even when the load acting on the impact support members 36 and 37 of the impact resistant support device 50 is large, the bolt 46 is attached by the intermediate impact support member 42 provided in the through hole 35 of the holding member 32. There is no contact with the holding member 32.

  Therefore, according to such an impact-resistant support device 50, vibrations and impacts generated on the supported body 201 and vibrations and impacts from the support body 200 are attenuated by the impact support members 36 and 37 and are supported. Since it is transmitted to the support 201, vibrations and impacts are reduced by the impact support members 36 and 37, and transmission of vibrations and impacts between the support 200 and the supported body 201 can be greatly reduced.

  Furthermore, also in this embodiment, if the impact support members 36 and 37 are pre-compressed by the impact support receivers 44 and 45 so as to apply a predetermined load in advance, the impact support members 36 and 37 are deformed during actual operation. Can be made a deformation in a pre-compressed range between the compressed state and the non-compressed state, and the impact support members 36 and 37 are not used with a tensile load, and are always used only with a compressive load. It is possible to prevent displacement, peeling, cracking, or the like between 36 and 37 and the impact support receivers 44 and 45. In the second embodiment, the pre-compression amount can be adjusted by the tightening force of the bolt 46.

  Also in this embodiment, the impact-resistant support device 50 is optimal in accordance with the mass of the supported body 201 (target apparatus or the like) that is the object to be supported, the load acting on the supported body 201, and the magnitude of the impact. What is necessary is just to set to a shape and arrangement | positioning.

  10 is a longitudinal sectional view of an impact resistant support device showing a third embodiment of the present invention, FIG. 11 is a plan view of the impact resistant support device, and FIG. 12 is a side view of the impact resistant support device. In the third embodiment, the support leg, the shock absorbing member, and the shock support receiver are different from the second embodiment described above. In addition, the same structure as 2nd Embodiment mentioned above is attached | subjected and the code | symbol which added 30 further is attached | subjected and demonstrated.

  As shown in FIG. 11, in the impact resistant support device 80 according to the third embodiment, the impact support members 66 and 67 are formed in a substantially square shape in plan view, similarly to the impact resistant support device 50 according to the second embodiment described above. The holding member 62 that supports the impact support members 66 and 67 is also formed in a substantially square shape. A side wall 85 having the same height as the support leg 61 is provided on the surface of the holding member 62 without the support leg 61. The side wall 85 and the support leg 61 form a space in which the substantially square impact support members 66 and 67 are provided.

  As shown in FIG. 10, also in the case of the third embodiment, the support leg 61 and the side wall 85 in contact with the outer surfaces of the impact support members 66 and 67 are approximately the thickness of the impact support members 66 and 67 (the vertical direction in the figure). The impact support members 66 and 67 are prevented from shifting in the width direction so as to receive a load.

  Also, as shown in these drawings, the impact support members 66 and 67 in the third embodiment are formed with concave surfaces 68 and 69 (hereinafter referred to as “curved surfaces”) that are curved toward the center. ing. That is, the anti-holding member side (upper surface or lower surface) of the impact support members 66 and 67 is formed by concave curved surfaces 68 and 69 that are recessed in a conical shape. Through holes 70 and 71 are provided in the center of the impact support members 66 and 67. The impact support members 66 and 67 are provided on the support side and the supported side of the holding member 62. The impact support members 66 and 67 are fixed by connecting the impact support receivers 74 and 75 formed in a conical shape with bolts 76 facing each other. The conical portions of the impact support members 74 and 75 are formed in a shape that matches the conical curved surfaces 68 and 69 of the impact support members 66 and 67.

  According to the impact resistant support device 80 of the third embodiment configured as described above, the curved surfaces 68 and 69 that are curved are formed on the impact support members 66 and 67, so that the curved surfaces 68 and 69 are in contact with each other. The curved surfaces 68 and 69 can receive loads from the impact support receivers 74 and 75 provided in this manner. Therefore, according to the impact resistant support device 80, the compression direction in which the impact supporting members 66 and 67 are pressed against the holding member 62, and the full width direction in which the curved surfaces 68 and 69 of the impact supporting members 66 and 67 are formed. It is possible to support loads acting on the

  In the case of the impact resistant support device 80 of this embodiment, the curved surfaces 68 and 69 formed in a conical shape can support the load acting in the entire width direction of the impact support members 66 and 67, so the first described above. Compared to the embodiment, the selection range of the support method of the support 201 is increased. Also in this embodiment, even when the load acting on the impact support members 66 and 67 of the impact resistant support device 80 is large, the bolts 76 are attached by the intermediate impact support member 72 provided in the through hole 65 of the holding member 62. There is no contact with the holding member 62.

  Therefore, according to such an impact-resistant support device 80, vibrations and impacts generated on the supported body 201 and vibrations and impacts from the support body 200 are attenuated by the impact support members 66 and 67 and are supported. Since the vibration is transmitted to the support 201, vibration and impact are reduced by the impact support members 66 and 67, and transmission of vibration and impact between the support 200 and the supported body 201 can be greatly reduced. it can.

  Further, in this embodiment, if the impact support members 66 and 67 are pre-compressed by the impact support receivers 74 and 75 so as to apply a predetermined load in advance, the impact support members 66 and 67 are deformed during actual operation. Can be made a deformation in a pre-compressed range between the compressed state and the non-compressed state, and the impact support members 66 and 67 are not subjected to a tensile load, and are always used only with a compressive load. 66, 67 and impact support receivers 74, 75 can be prevented from being displaced, peeled off, cracked, or the like. In the third embodiment, the pre-compression amount can be adjusted by the tightening force of the bolt 76.

  Also in this embodiment, the impact resistant support device 80 is optimal in accordance with the mass of the supported body 201 (target apparatus or the like) that is the object to be supported, the load acting on the supported body 201, and the magnitude of the impact. What is necessary is just to set to a shape and arrangement | positioning.

  In the first embodiment described above, the inclined surfaces 8 and 9 are formed on the two opposing surfaces of the impact support members 6 and 7, and in the second embodiment, the inclined surfaces 38 and 39 are provided on the four surfaces of the impact support members 36 and 37. In the third embodiment, the curved surfaces 68 and 69 are formed on the impact support members 66 and 67. However, the load in the width direction from the impact support receiver is formed by forming at least two concave surfaces. As long as it is an impact support member that can support the shock support member, other configurations may be used, and an impact support member having an inclined surface or a curved surface formed by a polygonal pyramid, a cone, or the like is disposed on at least one of the opposing surfaces via the holding member If so, the other side does not have to be formed with an inclined surface or a curved surface.

  In addition, the concave depths of these inclined surfaces 8, 9, 38, 39 (curved surfaces 68, 69) (the amount of indentation from the side opposite to the holding member) are also the impact support members 6, 7, 36, 37, 66, What is necessary is just to set according to the physical property of 67, the magnitude | size of the load to support, etc.

  By the way, in any of the above-described embodiments, the impact and vibration supported by the impact-resistant support devices 20, 50, 80 are provided above and below the holding members 2, 32, 62 provided on the support legs 1, 31, 61. The impact support members 6, 7, 36, 37, 66, 67 are damped by deformation, and the displacement of the impact support members 6, 7, 36, 37, 66, 67 in the width direction is the support leg 1 or the support. It is comprised so that it may suppress by the legs 31 and 61 and the side walls 55 and 85. FIG.

  Therefore, depending on the use conditions, it may not be possible to reduce the impact acceleration, which is satisfactory because the deformation of the impact support member is suppressed. In that case, the following shock-resistant support device is used to further reduce the shock acceleration by further lowering the eigenvalue of the system in the shock-resistant support device.

In FIG. 13, the attachment portion 93 is fixed to the support body 200 with a bolt 111. These are made of a hard material such as metal.

  The holding member 92 is provided substantially in parallel with the attachment surface of the attachment portion 93, and a through hole 95 is provided in the center. In this embodiment, these are integrally formed by bending, and as shown in the cross-sectional view shown in FIG. The periphery is thick in the middle, and the periphery is the same thickness as the support legs 91.

  Further, impact support members 96 and 97 are provided on the support side (lower side in the figure) and the supported side (upper side in the figure) of the holding member 92. As the impact support members 96 and 97, as in the first embodiment described above, a high attenuation material with an attenuation ratio in the range of 40% to 80% is preferable, and in particular, a high attenuation material made of ether-based polyurethane is preferable. .

  As described above, the impact support members 96 and 97 are in contact with the holding member 92 having a different thickness as described above, and an intermediate impact support member 102 described later provided in the through hole 95 of the holding member 92. It is formed of a stepped surface, and the anti-holding member side is formed of concave curved surfaces 98 and 99 (a spherical surface or a part of an ellipsoid). By forming the contact surfaces of the impact support members 96, 97 and the holding member 92 in a step shape, the contact area between them is increased. In this fourth embodiment, penetrating bolt holes 100 and 101 are provided at substantially the center portions of the curved surfaces 98 and 99 formed in a concave shape so as to be recessed toward the center portions of the impact support members 96 and 97. .

  In the fourth embodiment, curved surfaces 98 and 99 are formed on both impact support members 96 and 97 provided on both surfaces of the holding member 92. The curved surfaces 98 and 99 may be formed only on one of the impact support members 96 (97) on the support side or the supported side, depending on use conditions or the like.

  A hollow cylindrical intermediate impact support member 102 is provided in the through hole 95 of the holding member 92. The intermediate impact support member 102 has an outer shape that is substantially the same as the diameter of the through hole 95, a thickness that is thicker than the thickest portion of the holding member 92, and a bolt hole 103 provided in the center. . The hardness of the intermediate impact support member 102 may be the same as or different from that of the impact support members 96 and 97, but if a material harder than the impact support members 96 and 97 is used, the bolt 106 to be inserted into the bolt hole 103 is used. The tilt can be suppressed, which is preferable.

  In a state where the intermediate impact support member 102 is provided in the through hole 95 of the holding member 92, impact support members 96 and 97 are provided on the support side and the supported side of the holding member 92. 104 and 105 are fixed with bolts 106. The impact support receiver 105 on the lower side of the figure is formed in a curved surface such that the holding member 92 side (inner side) is along the curved surface 99 of the impact support member 97, and the anti-holding member side (outer side) is substantially parallel to the holding member 92. It is formed on a flat surface. In addition, a shock absorbing material 114 formed of a high damping material is embedded in the shock support receiver 105 at the center so that the shock can be reduced even if the shock support receiver 105 and the head of the bolt 106 come into contact with each other. Yes. The buffer material 114 is formed in a columnar shape so that the head portion and the shaft portion of the bolt 106 do not come into contact with the impact support receiver 105. As will be described later, the buffer material 114 can avoid metal contact with the impact support receiver 105 when the head of the bolt 106 is separated and returned due to impact or the like. The support body 200 is provided with a hole 202 so that the head of the bolt 106 does not come into contact with the support body 200 even if it is separated from the impact support receiver 105.

  The impact support receiver 104 on the upper side of the drawing is formed in a curved surface such that the holding member side (inner side) is along the curved surface 98 of the impact support member 96, and the anti-holding member side (outer side) is substantially parallel to the holding member 92. It is formed in such a plane. A bolt hole 109 into which a screw portion of the bolt 106 inserted from the lower impact support 105 is screwed is formed in the center portion.

  When the bolt 106 is inserted from the lower impact support receiver 105 and screwed into the bolt hole 109 of the upper impact support receiver 104, the mounting of the impact support members 96 and 97 is completed. In the state shown in FIG. 13, the support leg 91 is fixed to the support 200 with bolts 111, the upper impact support receiver 104 is fixed to the support 201 with bolts 113, and the impact-resistant support device 110 is arranged at a predetermined position. It has been installed. 112 is a tapped hole.

  As described above, in the fourth embodiment, in order to increase the space in which the impact support members 96 and 97 can be displaced, the walls that limit the displacement in the width direction of the impact support members 96 and 97 are removed, and the impact support members 96 and 97 are removed. By securing a space in which 97 can be freely displaced (deformed), the impact acceleration is further reduced.

  Further, even if the impact support members 96 and 97 are greatly displaced and the bolt 106 is largely inclined, the height of the intermediate impact support member 102 is increased so that the bolt 106 does not buffer the holding member 92. At the same time, the hardness is higher than that of the impact support members 96 and 97. The intermediate buffer support member 102 is also made of a high damping material made of ether polyurethane or the like.

  FIG. 16 is a longitudinal sectional view showing an operation when the impact resistant support device shown in FIG. 13 receives a load, (a) is a tensile direction load, and (b) is a longitudinal sectional view when a compression direction load is received. It is. In the fourth embodiment, the displacement of the impact support members 96 and 97 is increased, and the eigenvalue of the impact support member is further lowered as follows.

  As shown in FIG. 16 (a), when the impact support device 110 receives a load in the tensile direction from the supported body 201, the impact support receiver 104 fixed to the supported body 201 rises, and this impact support receiver 104. At the same time, the bolt 106 is raised, so that the lower impact support member 97 is compressed and deformed by the head of the bolt 106. At this time, since the upper impact support receiver 104 and the impact support member 96 are not separably bonded, the upper impact support receiver 104 floats away from the impact support member 96. Therefore, when receiving a load in the tensile direction, the impact (vibration) is supported only by the compressive deformation of the impact support member 97 provided below the holding member 92.

  On the other hand, as shown in FIG. 16B, when the impact support device 110 receives a load in the compression direction from the supported body 201, the impact support receiver 104 fixed to the supported body 201 is coupled only to the bolt 113. Therefore, the head of the bolt 106 moves away from the lower impact support receiver 105 while compressing and deforming the upper impact support member 96 with the impact support receiver 104. Therefore, when a load in the compression direction is received, the impact (vibration) is supported only by the compressive deformation of the impact support member 96 provided on the upper side of the holding member 92. When returning from this state to the state shown in FIG. 13, the head of the bolt 106 comes into contact with the shock-absorbing material 114 embedded in the impact support receiver 105, so that the bolt 106 is in metal contact with the impact support receiver 105. Never do.

  That is, according to the impact support device 110 of this embodiment, when the impact resistant support device 110 receives a compression or tensile load, the impact support device 96 is provided on the upper side of the holding member 92 or is provided on the lower side. The impact (vibration) is supported by the deformation of only one of the impact support members 97.

  Therefore, according to the impact-resistant support device 110 configured in this way, the impact and vibration acting on the support 200 from the support 200 or from the support 201 to the support 200 are applied to the upper and lower impact support members 96. , 97, it is possible to provide a highly damped impact resistant support with a lower eigenvalue.

  In the first embodiment, the inclined surface 8 between the impact support member 6 and the impact support receiver 14 is used. In the second embodiment, the inclined surface 38 between the impact support member 36 and the impact support receiver 44 is used. In the embodiment, by configuring the inclined surface 68 between the impact support member 66 and the impact support receiver 74 so as to be separable without bonding, in any embodiment, as in the fourth embodiment, the holding member Only by the deformation of the impact support member 96 (97) provided on one of the upper and lower sides of 92, the impact support and vibration can be supported and the impact support with a lower eigenvalue can be realized.

  In this way, either one of the impact support members 96 or 97 provided above and below the holding member 92 is configured to absorb impact or vibration, or both of the impact support members 96 and 97 absorb impact or vibration. Whether to configure may be determined according to use conditions and the like.

  FIG. 17 is a longitudinal sectional view of an impact resistant support device showing a fifth embodiment of the present invention. In the fifth embodiment, by increasing the length (height) of the impact support member in the fourth embodiment, the impact support member can be displaced more greatly to reduce impact and vibration. It is. In addition, the same code | symbol is attached | subjected to the structure same as 4th Embodiment, and the detailed description is abbreviate | omitted. In addition, the code | symbol which added 30 further is attached | subjected to the structure same as 4th Embodiment mentioned above, and detailed description is abbreviate | omitted.

  As shown in the figure, the shock-resistant support device 140 according to the fifth embodiment also has a holding member 122 between support legs 121 (the figure is fixed to the support 200) fixed to one of the support 200 or the supported body 201. In this embodiment, the support leg 121 and the holding member 122 are formed into a tall and integrated horse shape. These are made of a hard material such as metal.

  The holding member 122 is provided substantially parallel to the attachment surface of the attachment portion 123, and a through hole 125 is provided substantially at the center. In this embodiment, these are integrally formed by bending. The circumference of the through hole 125 is thick in the compression direction (vertical direction shown in the figure), and becomes an intermediate thickness while drawing an arc from there, and the circumference is the same thickness as the support leg 121. Yes.

  Further, impact support members 126 and 127 are provided on the support body side (lower side in the figure) and the supported body side (upper side in the figure) of the holding member 122. As the impact support members 126 and 127, similarly to the fourth embodiment described above, a high attenuation material with an attenuation ratio in the range of 40% to 80% is preferable, and in particular, a high attenuation material made of ether-based polyurethane is preferable. .

  As described above, the impact support members 126 and 127 are in contact with the holding member 122 having a different thickness as described above and the intermediate impact support member 132 (described later) provided in the through hole 125 of the holding member 122. The anti-holding member side is formed of concave curved surfaces 128 and 129 (a spherical surface or a part of an ellipsoid). By forming the contact surfaces of the impact support members 126 and 127 and the holding member 122 into arc shapes having different thicknesses, the contact area between them is increased. Also in the fifth embodiment, the bolt holes 130 and 131 are provided at substantially the center portions of the curved surfaces 128 and 129 formed in a concave shape so as to be recessed toward the center portions of the impact support members 126 and 127.

  Also in the fifth embodiment, curved surfaces 128 and 129 are formed on both impact support members 126 and 127 provided on both surfaces of the holding member 122. The curved surfaces 128 and 129 may be formed only on one of the impact support members 126 (127) on the support side or the supported side, depending on use conditions or the like.

  A hollow cylindrical intermediate impact support member 132 is provided in the through hole 125 of the holding member 122. The middle impact support member 132 has an outer shape that is substantially the same as the diameter of the through hole 125, a thickness that is thicker than the thickest portion of the holding member 122, and a bolt hole 133 at the center. . The hardness of the intermediate impact support member 132 may be the same as or different from that of the impact support members 126 and 127, but if a material harder than the impact support members 126 and 127 is used, the bolt 136 to be inserted into the bolt hole 133 is used. The tilt can be suppressed, which is preferable. A cushioning material 145 is provided on the inner side of the support leg 121 so that the tilted bolt 136 does not contact the metal.

  In a state where the intermediate impact support member 132 is provided in the through hole 125 of the holding member 122, impact support members 126 and 127 are provided on the support side and the supported side of the holding member 122. 134 and 135 are fixed with bolts 136. The impact support receiver 135 on the lower side of the drawing is formed in a curved surface such that the holding member 122 side (inner side) is along the curved surface 129 of the impact support member 127, and the anti-holding member side (outer side) is substantially parallel to the holding member 122. It is formed on a flat surface. In addition, the shock support receiver 135 is embedded with a buffer material 144 made of a high damping material so that the shock can be mitigated even if the shock support receiver 135 and the head of the bolt 136 come into contact with each other. Yes. The buffer material 144 is formed in a columnar shape so that the head portion and the shaft portion of the bolt 136 do not come into contact with the impact support receiver 135. As will be described later, the buffer material 144 can avoid metal contact with the impact support receiver 135 when the head of the bolt 136 is separated and returned due to impact or the like. The support body 200 is provided with a hole 202 so that the head of the bolt 136 does not come into contact with the support body 200 even if it is separated from the impact support receiver 135. The impact support receiver 134 on the upper side of the drawing is formed in a curved surface such that the holding member side (inner side) is along the curved surface 128 of the impact support member 126, and the anti-holding member side (outer side) is substantially parallel to the holding member 122. It is formed in such a plane. A bolt hole 139 is formed in the central portion to which the screw portion of the bolt 136 inserted from the lower impact support receiver 135 is screwed.

  When the bolt 136 is inserted from the lower impact support receiver 135 and screwed into the bolt hole 139 of the upper impact support receiver 134, the mounting of the impact support members 126 and 127 is completed. In the state of FIG. 17, the support leg 121 is fixed to the support 200 with bolts 141, the upper impact support receiver 134 is fixed to the supported body 201 with bolts 143, and the impact-resistant support device 140 is arranged at a predetermined position. It has been installed.

  As described above, in the fifth embodiment, in order to increase the space in which the impact support members 126 and 127 can be displaced, the walls that limit the displacement in the width direction of the impact support members 126 and 127 are removed, and the impact support members 126 and 127 are removed. By securing a space in which 127 can be freely displaced (deformed), the impact acceleration is further reduced.

  Further, even if the impact support members 126 and 127 are greatly displaced and the bolt 136 is largely inclined, the height of the intermediate impact support member 132 is increased so that the bolt 136 does not buffer the holding member 122. At the same time, the hardness is higher than that of the impact support members 126 and 127. The intermediate buffer support member 132 is also made of a high damping material made of ether polyurethane or the like. Note that the damping material 145 provided inside the support leg 121 is also made of a high damping material made of ether polyurethane or the like.

  In the fifth embodiment, the size in the length direction to be compressed is increased with respect to the size in the width direction in contact with the holding member 122 of the impact support members 126 and 127, but the ratio of increasing the length size is as follows. What is necessary is just to determine according to use conditions etc., such as the quantity which the impact support members 126 and 127 can displace.

  According to the impact-resistant support device 140 configured in this way, shock and vibration acting on the support 201 from the support 200 or from the support 201 to the support 200 are applied to the support side of the holding member 122 and the support. Since it is supported by the impact support members 126 and 127 having a large length provided on the support side, it is possible to provide impact resistant support with higher attenuation. That is, the impact support members 126 and 127 having a large length can be displaced (deformed) more greatly, and the impact and vibration can be greatly attenuated.

  Moreover, according to the fifth embodiment, since the length of the impact support members 126 and 127 is large, the impact support members 126 and 127 are also deformed in the torsion direction in addition to the compression and collapse of the impact support members 126 and 127 to attenuate the impact and vibration. Therefore, impact and vibration can be reduced with a very high damping rate.

  Also, in this embodiment, the upper impact support member 126 and the impact support receiver 134 are not separably bonded, so that when the supported body 201 receives an impact or vibration that moves downward, the upper impact support member 126 and the impact support receiver 134 are separated. Although the impact support member 126 is compressed and deformed, only the bolt 136 is lowered downward on the lower side, so that the impact is attenuated only by the deformation of the upper impact support member 126.

  On the other hand, when the support 200 receives an impact or vibration that moves upward, the lower impact support member 127 is compressed and deformed by the bolt 136, but the upper impact support receiver 134 is impacted by the bolt 106. Therefore, the impact is attenuated only by the deformation of the lower impact support member 127.

  That is, when the impact resistant support device 140 receives a load in the compression or tensile direction, only one of the impact support member 126 provided on the upper side of the holding member 122 or the impact support member 127 provided on the lower side is deformed. Will support the impact (vibration).

  Therefore, according to the impact resistant support device 140 configured as described above, the impact and vibration acting on the support 200 from the support 200 or from the support 201 to the support 200 are applied to the upper and lower impact support members 126. , 127, it is possible to provide a shock-resistant support with high attenuation with a lower eigenvalue.

  It is possible to combine the configurations in any of the above-described embodiments. For example, the impact support members 36, 37, 66, and 67 in the second and third embodiments described above are replaced with the impact support in the fifth embodiment. If the members 126 and 127 are made larger, the amount of displacement of the impact support members 126 and 127 becomes larger, and the eigenvalue can be lowered to increase the damping effect.

  Further, the above-described embodiment is an embodiment, and various modifications can be made without departing from the spirit of the present invention, and the present invention is not limited to the above-described embodiment.

  The impact resistant support device according to the present invention is useful for mitigating impacts and vibrations transmitted to equipment and structures, and can be widely applied as an impact resistant support device in general consumer products.
