And a plurality of pairs of permanent magnets 5 and 6 arranged so that each pair is opposite to each other with the same polarity, and the upper magnet 5 of each permanent magnet pair 5 and 6 is connected to the shelf body. 4 is attached to a required portion on the lower surface side of the bottom plate 4a, the lower magnet 6 of each permanent magnet pair 5, 6 is attached to the upper surface side of the substrate 3a of the shelf outer frame 3, and the repulsive force of each permanent magnet pair 5, 6 is used. The horizontal swing restricting means 7 that floats the shelf main body 4 and restricts the horizontal swing of the shelf main body 4 is provided between an outer peripheral side required portion of the shelf main body 4 and an inner required portion of the shelf outer frame 4 opposed thereto. It is something in between. In FIG. 1, 1 c denotes a rear opening / closing door of the van 1.

上記免震棚装置２の構造について更に詳しく説明すれば、棚本体４は、図２の(a) 及び(b) に示すように、矩形板状の底板４ａと、この底板４ａの四隅に立設された矢板状の支柱４ｂ・・・と、これら支柱４ｂ・・・のうち左右各側の前後支柱４ｂ，４ｂ間に介装された左右側板４ｃ，４ｃと、背面側の左右支柱４ｂ，４ｂ間に介装された背面板４ｄと、天板４ｅとからなるもので、左右側板４ｃ，４ｃ間には棚板４ｆが複数段に架け渡されている。また、この棚本体４の前面側開口部には引き違いガラス障子４ｇ，４ｇが装備される。   If the structure of the said seismic isolation rack apparatus 2 is demonstrated in detail, as shown to (a) and (b) of FIG. 2, the shelf main body 4 will stand in the four corners of the rectangular-plate-shaped bottom plate 4a and this bottom plate 4a. A sheet pile-shaped column 4b, a left and right plate 4c, 4c interposed between the left and right columns 4b, 4b, and a left column 4b, It consists of a back plate 4d interposed between 4b and a top plate 4e, and a shelf plate 4f is spanned in multiple stages between the left and right side plates 4c, 4c. Further, the front side opening of the shelf body 4 is equipped with sliding glass shoji 4g and 4g.

棚外枠３は、図２の(a) 及び(b) に示すように、基板３ａと、この基板３ａの四隅に立設された矢板状の支柱３ｂ・・・と、各支柱３ｂの内側に沿って支柱３ｂと一体的に設けられた丸パイプ３ｃ・・・とからなるもので、各丸パイプ３ｃの上端部側及び下端部側には棚本体４の外隅部に対向する位置に、夫々スリット８（図３参照）が設けられている。各丸パイプ３ｃの上端部は、バン１の天井壁部１ｂまで伸びて、それに固定されるようになっている。   As shown in FIGS. 2 (a) and 2 (b), the shelf outer frame 3 includes a substrate 3a, a sheet pile-like column 3b erected on the four corners of the substrate 3a, and an inner side of each column 3b. , And the round pipes 3c provided integrally with the support pillars 3b. The upper end side and the lower end side of each round pipe 3c are at positions facing the outer corners of the shelf body 4. Each of them is provided with a slit 8 (see FIG. 3). The upper end portion of each round pipe 3c extends to the ceiling wall portion 1b of the van 1 and is fixed thereto.

各永久磁石対５，６は、永久磁石のうちでは最も強力なネオジム磁石からなるもので、各磁石５，６は、例えば直径が５０ｍｍ、厚さが１０ｍｍの円板状磁石を使用しており、そして図２の(a) ，(b) から分かるように、この永久磁石対５，６の上部側磁石５は、棚本体４を形成する底板４ａ下面の左右両側の前後端部と中央部の前後端部との６箇所に取り付けられ、また下部側磁石６は、棚外枠３を形成する基板３ａ上面における各上部側磁石５の真下位置に取り付けられている。   Each pair of permanent magnets 5 and 6 is composed of the strongest neodymium magnet among the permanent magnets. Each magnet 5 and 6 uses, for example, a disk-shaped magnet having a diameter of 50 mm and a thickness of 10 mm. As can be seen from FIGS. 2A and 2B, the upper magnets 5 of the permanent magnet pairs 5 and 6 are arranged at the front and rear end portions and the central portion on the left and right sides of the bottom surface of the bottom plate 4a forming the shelf body 4. The lower-side magnet 6 is attached at a position directly below each upper-side magnet 5 on the upper surface of the substrate 3a forming the shelf outer frame 3.

また図２の(a) ，(b) に示すように、棚本体４の底板４ａ下面と棚外枠３の３ａ上面との間には、各永久磁石対５，６の下部側磁石６に対する上部側磁石５の強い反発によって棚本体４が跳ね上がるのを防止するコイルバネ９が、棚本体底板４ａの左右両側前後位置の４箇所に介装連結されている。また、棚外枠３の基板３ａ上には、トラックが大きな段差のあるところを走行する時に車体が傾斜して棚本体４の一端側が下がり過ぎるのを防止するために、その下がりかけた棚本体４の底板４ａ下面部を支持する弾性支持部材１０が複数箇所に突設されている。この弾性支持部材１０はスポンジ材からなるものである。   Further, as shown in FIGS. 2A and 2B, between the lower surface of the bottom plate 4a of the shelf main body 4 and the upper surface of 3a of the shelf outer frame 3, the permanent magnet pairs 5 and 6 are connected to the lower magnets 6 respectively. Coil springs 9 for preventing the shelf body 4 from jumping up due to the strong repulsion of the upper magnet 5 are interlaced and connected at four positions on the left and right sides of the shelf body bottom plate 4a. Further, on the substrate 3a of the shelf outer frame 3, the shelf body that has been lowered is prevented in order to prevent the vehicle body from being inclined and the one end side of the shelf body 4 from being lowered too much when the truck travels on a large step. The elastic support members 10 that support the bottom surface of the bottom plate 4a of the four project at a plurality of locations. The elastic support member 10 is made of a sponge material.

前記横振れ規制手段７は、図２の(a) ，(b) 及び図３に示すように、棚本体４の四隅に立設されている矢板状支柱４ｂ・・・の夫々上下両端部から外向きに突出するガイドピン１１，１１と、棚外枠３の四隅に夫々立設された矢板状支柱３ｂの内側に取り付けてある丸パイプ３ｃの上下両端部に形成されていて、前記ガイドピン１１が上下スライド可能に突入する上下スリット８，８とによって構成される。   As shown in FIGS. 2 (a) and 2 (b) and FIG. 3, the horizontal run-out restricting means 7 is provided from both upper and lower ends of the sheet pile-like columns 4b. Guide pins 11 and 11 projecting outward, and formed at the upper and lower ends of a round pipe 3c attached to the inside of a sheet pile-like column 3b erected at the four corners of the shelf outer frame 3, respectively. 11 is constituted by upper and lower slits 8 and 8 that slidably move up and down.

この横振れ規制手段７は、各永久磁石対５，６の反発力によって棚本体４が浮上していることから、その浮上したままの状態では横振れして不安定となるため、棚本体４側のガイドピン１１が棚外枠３側の丸パイプ３ｃのスリット８に突入係合してその横揺れを規制する、つまり振れ止めを行ない、それによって棚本体４を棚外枠３内に安定状態で浮上させることができる。   Since the shelf main body 4 is levitated by the repulsive force of each permanent magnet pair 5, 6, the lateral shake restricting means 7 oscillates in an unstable state and becomes unstable. Side guide pin 11 enters and engages with the slit 8 of the round pipe 3c on the shelf outer frame 3 side to restrict its roll, that is, to prevent the swing, thereby stabilizing the shelf body 4 in the shelf outer frame 3 It can be raised in the state.

この横振れ規制手段７では、図２の(a) から分かるように、棚本体４側のガイドピン１１が、棚本体４の隅部においてその隅角９０°の２等分線に沿って外向きに突出し、このガイドピン１１が突入するスリット８も棚外枠３の隅部でその隅角９０°の２等分線に沿うように丸パイプ３ｃに形成されているから、棚本体４が左右横方向に振れ、また前後横方向に振れ、更には斜め横方向に振れたとしても、それらあらゆる方向の横振れを有効に吸収することができる。   As can be seen from FIG. 2 (a), in this lateral shake restricting means 7, the guide pin 11 on the shelf body 4 side is removed along the bisector of the corner angle of 90 ° at the corner of the shelf body 4. Since the slit 8 projecting in the direction and the guide pin 11 enters is also formed in the round pipe 3c along the bisector of the corner angle 90 ° at the corner of the shelf outer frame 3, the shelf body 4 is Even if the camera shakes in the horizontal direction, the horizontal and horizontal directions, and even in the diagonal horizontal direction, the horizontal shake in all directions can be effectively absorbed.

上記のように構成されるトラック輸送用免震棚装置２によれば、棚本体４の棚板４ｆに形崩れのし易い食品、例えばデコレーションケーキを載置して目的地まで運搬する時に、走行中の車体が振動しても、その振動は、棚外枠３には伝わるが、棚本体４に伝わることがない。即ち、棚本体４は、棚本体４の底板４ａと棚外枠３の基板３ａとの間に介設されていて、各対が同極どうし上下に対向するように配置された複数の永久磁石対５，６の上部側磁石５と下部側磁石６との反発力により浮上した状態にあって、棚外枠３との縁を切られており、また横振れ規制手段７によって棚本体４の横振れが阻止されているから、棚本体４内のデコレーションケーキは、棚板４ｆ上で静止状態にあり、形崩れを起こすことなく、元のままの状態で目的地まで運ぶことができる。   According to the seismic isolation rack device 2 for truck transportation configured as described above, when a food that is easily deformed, such as a decoration cake, is placed on the shelf plate 4f of the shelf body 4 and transported to the destination, the vehicle travels. Even if the inside vehicle body vibrates, the vibration is transmitted to the shelf outer frame 3 but is not transmitted to the shelf body 4. That is, the shelf body 4 is interposed between the bottom plate 4a of the shelf body 4 and the substrate 3a of the shelf outer frame 3, and a plurality of permanent magnets are arranged so that each pair has the same polarity and faces each other vertically. It is in a state of being levitated by the repulsive force between the upper magnet 5 and the lower magnet 6 of the pair 5, 6, and the edge of the shelf outer frame 3 is cut off. Since the horizontal shake is prevented, the decoration cake in the shelf body 4 is in a stationary state on the shelf board 4f, and can be transported to the destination as it is without being deformed.

また、各永久磁石対５，６の反発力が強いため、その反発力で棚本体４が跳ね上がり過ぎる場合があるが、棚本体４の底板４ａ下面側と棚外枠３の３ａ上面側との間に、跳ね上がり防止用のコイルバネ９が棚本体底板４ａの左右両側前後位置の４箇所に介装連結されているから、棚本体４が過度に跳ね上がることがなく、従って棚本体４を安定状態に保持することができる。   Further, since the repulsive force of each permanent magnet pair 5, 6 is strong, the shelf body 4 may jump up excessively due to the repulsive force, but the bottom plate 4 a lower surface side of the shelf body 4 and the 3 a upper surface side of the shelf outer frame 3 In the meantime, since the coil springs 9 for preventing the jumping are connected to the four positions on the left and right sides of the shelf body bottom plate 4a, the shelf body 4 does not jump up excessively, so that the shelf body 4 is in a stable state. Can be held.

また、トラックが大きな段差のあるところを走行する時には棚本体４の一端側が下がり過ぎて傾斜状態となり易いが、棚外枠３の基板３ａ上には、そのような棚本体４の下がり過ぎを防止する弾性支持部材１０が複数箇所に突設されているから、弾性支持部材１０によって、その下がりかけた棚本体４の底板４ａ下面が支持されるから、棚本体４を水平状態に保持することができる。   Further, when the truck travels on a large step, one end side of the shelf body 4 tends to be lowered and easily inclined, but the shelf body 4 is prevented from falling too much on the substrate 3a of the shelf outer frame 3. Since the elastic support member 10 is projected at a plurality of locations, the lower surface of the bottom plate 4a of the shelf body 4 that has been lowered is supported by the elastic support member 10, so that the shelf body 4 can be held in a horizontal state. it can.

上述した実施形態のトラック輸送用免震棚装置２は、トラックの荷台上に固定される棚外枠３と、棚外枠３内に配置される棚本体４とに分離されていて、棚本体４と棚外枠３との間に、各対が同極どうし上下に対向するように配置した複数の永久磁石対５，６を介設して、その上部側磁石５と下部側磁石６との反発力によって棚本体４を浮上させるようにすると共に、横振れ規制手段７によって棚本体４の横振れを規制するようにし、また棚本体４の底板４ａ下面側と棚外枠３の基板３ａ上面側との間に介装連結したコイルバネ９によって、上部側磁石５による棚本体４の跳ね上がりを防止するようにし、更に棚外枠３の基板３ａ上面に突設した弾性支持部材１０によって、段差のあるところでの走行時に弾性支持部材１０が棚本体４の底板４ａ下面を支持することによって、棚本体４を水平状態に保持するようにしたものであるが、この免震棚装置２において重要なことは、反発力を生じる永久磁石対５，６、横振れ規制手段７、跳ね上がり防止用コイルバネ９及び弾性支持部材１０のバランスであり、そのバランスをうまくとることによって、最良の免震効果を発揮させることができる。   The seismic isolation rack device 2 for truck transportation according to the above-described embodiment is separated into a shelf outer frame 3 fixed on a truck bed and a shelf main body 4 arranged in the shelf outer frame 3. A plurality of permanent magnet pairs 5 and 6 are arranged between the outer frame 3 and the shelf outer frame 3 so that each pair is opposed to each other with the same polarity, and the upper magnet 5 and the lower magnet 6 The shelf body 4 is levitated by the repulsive force of the shelf body, and the lateral shake of the shelf body 4 is restricted by the lateral shake restricting means 7, and the bottom surface 4a of the shelf body 4 and the substrate 3a of the shelf outer frame 3 are restricted.
