It is a thing. The shock-absorbing means 3 of the embodiment is a damper that is attached to the lower end of the car stop 2 housed in the outer cylinder 1 and collides with the hitting member 9 provided at the lower end of the outer cylinder 1. That is, the buffer means 3 has an oil-filled cylinder structure, in which a male screw 42a is formed on the outer circumference of the cylinder (outer cylinder) 40, and the cylinder 40 is passed through the buffer step mounting hole of the buffer plate 29 to buffer it. The cylinder 40 is fixed to the buffer plate 29 by tightening both sides of the plate 29 with a pair of nuts 43, and the tip of the piston rod 42 is hit to face the member 9. However, it is also possible to form a shock-absorbing means mounting hole of the shock-absorbing plate 29 into a screw hole, screw the cylinder 40 into this hole, and tighten only one of the shock-absorbing plate 29 with the nut 43 to fix it.
【００１４】 この緩衝手段３の内部構造を示す図９において、４１はインナーシリンダ、４ ４はピストン、４５はシリンダボトム、４６はピストン４４とシリンダボトム４ ５との間に介在した車止柱２の重量よりも弱いばね力のスプリング、４７はシリ ンダキャップ、４８はヘッド、４９はオイル、５０はインナーシリンダ４１に形 成されてインナーシリンダ４１とシリンダ４０との隙間４２ｂに連通しピストン ４４の移動により順次塞がれる多数のオリフィス、５１はバルブとしてのボール 、５２はアキュームレータとしてのスポンジ、５３はＯリング、５４はオイル注 入用等のボルト、５５は表示シール、５６は弾性パッキン、５７はオイルシール 、５８はダストリッド、５９はピン、６０は硬質の合成樹脂製または合成ゴム製 のキャップ、６１は流体流通切欠（図１１参照）である。In FIG. 9 showing the internal structure of the buffer means 3, 41 is an inner cylinder, 44 is a piston, 45 is a cylinder bottom, and 46 is a car stop column 2 interposed between the piston 44 and the cylinder bottom 45. A spring having a spring force weaker than the weight of 47, 47 is a cylinder cap, 48 is a head, 49 is oil, 50 is formed in the inner cylinder 41 and communicates with the gap 42b between the inner cylinder 41 and the cylinder 40. A large number of orifices that are sequentially closed by movement, 51 is a ball as a valve, 52 is a sponge as an accumulator, 53 is an O ring, 54 is a bolt for oil injection, 55 is an indicator seal, 56 is an elastic packing, 57 Is an oil seal, 58 is a dust lid, 59 is a pin, and 60 is made of hard synthetic resin or synthetic rubber. The cap 61 is a fluid flow cutout (see FIG. 11).
【００１５】 この緩衝手段３は、車止柱２の落下によりピストン４４のキャップ６０が当た り部材９に当たり、そのためピストン４４がスプリング４６を圧縮するとともに オイル４９を加圧しオリフィス５０を通してオイル４９を隙間４２ｂ側に流出さ せ、これによりピストン４４を減速させながら、ピストン４４がインナーシリン ダ４１内をストロークするのにしたがって、ピストン４４がオリフィス５０を塞 いでオイル４９のインナーシリンダ４１より外部に流出する流出面積が除々に減 少される。したがって、ピストン４４が減速される割合に応じてオリフィスの面 積が自動的に変化することができ、これによりピストン４４の全区間で常に一定 の油圧抵抗力を発生させることができる。またスプリング４６は車止柱２の重量 よりも弱いばね力であるので、最終的には車止柱２によりスプリング４６が圧縮 されて頭部５がカバー１５に載る。In this cushioning means 3, the cap 60 of the piston 44 hits the member 9 by the fall of the vehicle stop column 2, so that the piston 44 compresses the spring 46 and pressurizes the oil 49 to pass the oil 49 through the orifice 50. As the piston 44 strokes in the inner cylinder 41 while decelerating the piston 44, the piston 44 closes the orifice 50 and the oil 49 flows out from the inner cylinder 41 to the outside. The spill area is reduced gradually. Therefore, the area of the orifice can be automatically changed according to the rate at which the piston 44 is decelerated, and thus a constant hydraulic resistance force can be generated in the entire section of the piston 44. Further, since the spring 46 has a spring force weaker than the weight of the car stop column 2, the spring 46 is finally compressed by the car stop column 2 and the head 5 is placed on the cover 15.

As shown in FIG. 13, the absorbed energy E, the pushing force applied to the cushioning means 3 and the falling weight are converted into the weight of a simple horizontal collision. The distance H (about 600 mm), the stroke S of the piston (about 50 mm 2), the falling velocity V, the acceleration g of gravity, and the number of dampers n (n = 1 in the embodiment) are calculated by the following equations.

【００１８】 この実施の形態によれば、ガレージや道路の幅方向にほぼ等間隔に複数本埋設 した外筒１に車止柱２を収納することによりその道路等を自動車が通行可能とな り、車止柱２を外筒１より突出することにより自動車の通行が車止柱によって規 制される。この場合、車止柱２を突出状態から収納状態へ収納するために落下さ せる際に、車止柱２の頭部５と地面６側との間に足や手やその他の物が挟まって も、緩衝手段３により足等に対する衝撃を緩和することができるので、怪我や破 損を防止することができる。According to this embodiment, by storing car stop posts 2 in a plurality of outer cylinders 1 that are embedded at substantially equal intervals in the width direction of a garage or a road, an automobile can pass through the road or the like. By projecting the car stop 2 from the outer cylinder 1, the passage of the automobile is regulated by the car stop. In this case, when dropping the bollard 2 from the projecting state to the stowed state, when legs or hands or other objects are caught between the head 5 and the ground 6 side of the bollard 2. Also, since the shock absorber 3 can reduce the impact on the foot or the like, injury or damage can be prevented.
【００１９】 また緩衝手段３を、外筒１内に収納される車止柱２の下端部に取付けて、外筒 １の下端部に設けた当たり部材９に衝突するダンパとしたため、車止柱２を外筒 １から取り出してしまうことにより、緩衝手段３の取付けや交換が容易に行なえ る。 この考案の第２の実施の形態を図１４に示す。すなわち、この車止めは、第１ の実施の形態において、緩衝手段３が車止柱２内の上端部に取付けられて、外筒 １の下端部に設けた当たり部材９に衝突するようにしている。車止柱２の内部の 上端部にはたとえばねじ孔のある取付板６５を設けておき、ねじ孔に緩衝手段３ の雄ねじ４２ａをねじ込み、ナット４３により取付板６５に固定している。また 緩衝手段３はピストンロッド４２にジョイント６６等でロッド４２′を接続し、 ロッド４２′の先端の位置を図１のピストンロッド４２の先端と同じ位置となる ようにしている。Further, since the cushioning means 3 is attached to the lower end portion of the vehicle stop column 2 housed in the outer cylinder 1 and serves as a damper that collides with the hitting member 9 provided at the lower end portion of the outer cylinder 1, the vehicle stop column By removing 2 from the outer cylinder 1, the buffering means 3 can be easily attached and replaced. A second embodiment of this invention is shown in FIG. That is, in this car stop, in the first embodiment, the cushioning means 3 is attached to the upper end portion inside the car stop column 2 so as to collide with the hitting member 9 provided at the lower end portion of the outer cylinder 1. .

Alternatively, the tip of the piston rod of the cushioning means 3 may abut against the upper end surface of the strut when the car stop pole 2 falls. In addition, in the above-described embodiment, the cushioning means 3 may add a compression spring that is passed through the piston rod 42 between the head 48 and the cylinder 40. Further, in this invention, the cushioning means 3 may be any one as long as it absorbs an impact on an object. For example, a damper is provided on the bottom side of the outer cylinder 1, and the damper is attached to the lower end of the car stop column 2 or the upper end of the inside. It may be provided. Although the damper contained oil, it may be an electromagnetic damper, a friction damper, etc. in addition to the one that uses the viscosity and dynamic pressure of a fluid such as water or air. It is possible to use the one that is configured by and absorbs and absorbs shock. Further, the holding means 7 is not limited to the embodiment described above.
【００２２】[0022]
請求項１記載の車止めによれば、ガレージや道路の幅方向にほぼ等間隔に複数 本埋設した外筒に車止柱を収納することによりその道路等を自動車が通行可能と なり、車止柱を外筒より突出することにより自動車の通行が車止柱によって規制 される。この場合、車止柱を突出状態から収納状態へ収納するために落下させる 際に、車止柱の頭部と地面側との間に足や手やその他の物が挟まっても、緩衝手 段により足等に対する衝撃を緩和することができるので、怪我や破損を防止する ことができる。 According to the car stop according to claim 1, by storing the car stop pillars in a plurality of outer cylinders buried at substantially equal intervals in the width direction of the garage or the road, the car can pass through the roads, etc. The vehicle is regulated by the car stop by protruding the car from the outer cylinder. In this case, even if a foot, hand, or other object is caught between the head of the bollard and the ground side when dropping the bollard from the projecting state to the stowed state, a cushioning step is required. Since it is possible to reduce the impact on the feet, it is possible to prevent injury or damage.
【００２３】 請求項２記載の車止めによれば、請求項１の効果のほか、車止柱を外筒から取 り出してしまうことにより、緩衝手段の取付けや交換が容易に行なえる。 請求項３記載の車止めによれば、請求項１の効果のほか、梅雨時や大雨などに 雨水が外筒内に一時的に溜まるようなことがあっても、車止柱内の上端部の緩衝 部材が浸水するのを回避することができるので、緩衝手段３を防水構造にする必 要がなく、安価にできる。According to the vehicle stop of the second aspect, in addition to the effect of the first aspect, by removing the vehicle stop column from the outer cylinder, the cushioning means can be easily attached or replaced. According to the bollard according to claim 3, in addition to the effect of claim 1, even when rainwater temporarily collects in the outer cylinder during the rainy season or heavy rain, the upper end of the bollard is prevented. Since the buffer member can be prevented from being flooded, the buffer means 3 does not need to have a waterproof structure, and the cost can be reduced.
