Description

本発明は、安全柵に関する。より詳しくは、トラックのテールゲートリフターに取り付けて用いる折り畳み式安全柵に関する。 The present invention relates to safety fences. More particularly, it relates to a foldable safety fence attached to a tailgate lifter of a truck.

テールゲートリフターは、トラックに荷物の積み下ろしをする際に地上から荷台の高さまで昇降する装置である。台車やロールボックスパレット（かご車）のような車輪付きの物の積み下ろしによく用いられる。しかし、従来のリフターには荷物が転がり落ちるのを防ぐ高さ数センチメートルのストッパーがあるのみであり、人や物が傾いたときに、転倒・落下を防ぐことはできない。かご車や人の転倒・落下を防ぐ為には、柵が必要である。 A tailgate lifter is a device that raises and lowers cargo from the ground to the height of the cargo bed when loading and unloading cargo on a truck. Often used for loading and unloading wheeled items such as carts and roll box pallets. However, conventional lifters only have stoppers several centimeters high to prevent objects from rolling down, and they cannot prevent people or objects from falling or falling when they are tilted. Fences are necessary to prevent cars and people from overturning and falling.

The safety fence 1 is fixed to the floor slab 3 by the mounting part 10 provided at the lower end of the fence part 12.例文帳に追加

＜装着部＞
図２は装着部１０を床版３に取り付けた状態を示す斜視図である。
図１および図２に示す通り、装着部１０は、折り畳み式安全柵１をテールゲートリフターの床版３に取り付けるための機構である。
床版３に、装着部１０を構成するコ字金具１０１の孔に対応する孔を開け、図３および図４に示す通り、３箇所の孔を有するコ字金具１０１を、床版３に被せる。実施例では、床版３およびコ字金具１０１に各三箇所の孔を開けている。
図５に示す通り、床版３及びコ字金具１０１の各孔に左ボルトＬＢおよび右ボルトＲＢを通し、反対側からナットを締め付けることで、コ字金具１０１を床版３に固定する。実施例では、上からボルトを通し、下からナットで留めているが、逆でもよい。
次に、ネジ穴を有する桁部１１の装着棒１０２を、床版３およびコ字金具１０１の残りの孔（中央）に通し、下側から中央ボルトＣＢを締め付けることで、装着部１０と桁部１１が接合され、安全柵１がリフターの床版３に取り付けられる。 <Wearing part>
FIG. 2 is a perspective view showing a state where the mounting portion 10 is attached to the floor slab 3. As shown in FIG.
As shown in FIGS. 1 and 2, the attachment part 10 is a mechanism for attaching the folding safety fence 1 to the floor slab 3 of the tailgate lifter.
The floor slab 3 is provided with holes corresponding to the holes of the U-shaped metal fittings 101 forming the mounting portion 10, and the floor slab 3 is covered with the U-shaped metal fittings 101 having three holes as shown in FIGS. . In the embodiment, the floor slab 3 and the bracket 101 are provided with three holes each.
As shown in FIG. 5, the U-shaped metal fitting 101 is fixed to the floor slab 3 by passing the left bolt LB and the right bolt RB through the respective holes of the floor slab 3 and the U-shaped metal fitting 101 and tightening nuts from the opposite sides. In the embodiment, the bolt is passed through from above and the nut is fastened from below, but the reverse is also possible.
Next, the mounting rod 102 of the girder 11 having screw holes is passed through the floor slab 3 and the remaining hole (center) of the U-shaped metal fitting 101, and the mounting part 10 and the girder are attached by tightening the central bolt CB from below. The part 11 is joined and the safety fence 1 is attached to the floor slab 3 of the lifter.

安全柵１を安定させる為に、装着部１０は２箇所以上あることが望ましいが、１箇所でもよい。もちろん、３箇所以上でもよい。
また、前述の構造に限らず安全柵１を床版３に取り付けられる構造であれば、いわゆる万力の様に挟み込む機構や、床版３にネジ穴を開けて桁部１１を締め付けて固定するなど、従来の種々の技術を用いることができる。 In order to stabilize the safety fence 1, it is desirable that there are two or more attachment portions 10, but one attachment portion may be provided. Of course, it may be three or more.
In addition, not limited to the structure described above, any structure in which the safety fence 1 can be attached to the floor slab 3 can be fixed by a mechanism such as a so-called vice-like sandwiching mechanism, or by opening a screw hole in the floor slab 3 and tightening the girder portion 11. Various conventional techniques can be used.

図２に示す通り、テールゲートリフターは荷物の積み下ろしの為に、傾斜して（図では紙面奥から手前に）着地するので、装着部１０が地面に当たり床版３が着地するのを妨げることも考えられる。そのため、地面との間に隙間が空かない様に、取り付け位置は車両側とすることが望ましい。 As shown in FIG. 2, the tailgate lifter lands at an angle (from the back to the front in the figure) for loading and unloading cargo, so the mounting part 10 hits the ground and prevents the floor slab 3 from landing. Conceivable. Therefore, it is desirable that the mounting position be on the vehicle side so that there is no gap with the ground.

また、連結部１１１および回転規制手段１３や回転抑制手段１４を床版３に直接取り付けて、装着部１０および桁部１１を備えない構成とすることもできる。 Alternatively, the connecting portion 111 and the rotation restricting means 13 and the rotation restricting means 14 may be directly attached to the floor slab 3 so that the mounting portion 10 and the girder portion 11 are not provided.

＜桁部＞
図３および図４に示す通り、桁部１１と柵部１２は、連結部１１１にて連結される。本実施例では、回転規制手段１３および回転抑制手段１４の一部を桁部１１上に備えている。 <Girder>
As shown in FIGS. 3 and 4 , the girder portion 11 and the fence portion 12 are connected by a connecting portion 111 . In this embodiment, part of the rotation restricting means 13 and the rotation restricting means 14 is provided on the girder portion 11 .

＜柵部＞
図５に示す通り、柵部１２は、柱１２１および手摺部１２３を有する。
柵部１２を倒した状態から直立させる回転を正回転と呼び、直立した状態から倒す回転を逆回転と呼ぶ。
柵部１２は、人等の転落を防ぐ為に充分な高さ（少なくとも７０～８０ｃｍ）であることが望ましい。
実施例では柱１２１を３本としているが、１本や２本としてもよいし、４本以上としてもよい。また、実施例では、各柱１２１の中間部を繋ぐ梁１２２が１本設けられているが、設けなくてもよいし、２本以上設けてもよい。 <Fence>
As shown in FIG. 5 , the fence section 12 has a pillar 121 and a handrail section 123 .
The rotation to make the fence part 12 stand upright from the knocked down state is called forward rotation, and the rotation to knock down the fence part 12 from the upright state is called reverse rotation.
It is desirable that the fence 12 has a sufficient height (at least 70 to 80 cm) to prevent people from falling.
In the embodiment, three pillars 121 are used, but one, two, or four or more pillars may be used. Also, in the embodiment, one beam 122 is provided to connect the intermediate portions of the columns 121, but it may not be provided, or two or more beams may be provided.

図６および図８に示す通り、安全柵１をリフターの左右に備える場合は、各柵部１２の高さを床版３の幅の半分以下にすることで、折り畳んだときに、柵部１２どうしが重ならなくなる。もちろん、図７に示す通り、折り畳んだときに柵部１２どうしが重なる構成としてもよい。 As shown in FIGS. 6 and 8, when the safety fences 1 are provided on the left and right sides of the lifter, the height of each fence 12 is half or less than the width of the floor slab 3, so that when folded, the fences 12 It will not be heavy. Of course, as shown in FIG. 7, the fences 12 may overlap each other when folded.

図５に示す通り、手摺部１２３にゴムガード１２４を備えることもできる。ゴムガード１２４は、柵部１２を閉じた際に、柵部１２と床版３が接触して互いに傷つくのを防いだり、柵部１２と床版３の間に指などが挟まるのを防いだりする効果がある。また、テールゲートリフターを畳んだ際に、柵部１２がトラックの後部扉などに当たって傷つくのを防ぐ効果もある。ゴムガード１２４の材質は、ゴムに限らず、他の樹脂材や発泡剤など衝撃を吸収して傷付きを防止できるものであればよい。 As shown in FIG. 5, the handrail portion 123 can also be provided with a rubber guard 124 . When the fence part 12 is closed, the rubber guard 124 prevents the fence part 12 and the floor slab 3 from coming into contact with each other and damaging each other, and prevents fingers from being caught between the fence part 12 and the floor slab 3. effective. Also, when the tailgate lifter is folded, the fence 12 is prevented from being damaged by contact with the rear door of the truck. The material of the rubber guard 124 is not limited to rubber as long as it can absorb impact and prevent damage, such as other resin materials or foaming agents.

柵部１２は、人や物の転倒や落下を防ぐという用を成せば、上述した柱と梁を有する構造に限らず、枠の内側に網を張った構成や、パンチングメタルなどの一枚の板などを用いることもできる。 The fence part 12 is not limited to the structure having the pillars and beams described above, as long as it serves to prevent people or objects from falling or falling. A plate or the like can also be used.

＜回転規制手段＞
安全柵１は、回転規制手段１３を有する。
図９に示す通り、回転規制手段１３は、係止体１３０、張出板１３２および引手１３３を有する。
回転規制手段１３は連結部１１１に備えられる。実施例では、３つの連結部１１１のうち真ん中の連結部１１１に備えているが、これに限らず、どの連結部１１１に備えてもよい。
引手１３３を一方に（図面上、右に）引くと、係止体１３０がスライド（図面上、右に移動）し張出板１３２の押さえが外れることで、係止状態から解放状態になり、柵部１２が回転自由となる。つまり、柵部１２を閉じることができる。
図１、図３および図５のように、柵部１２を直立させた状態で、引手１３３を他方に（図面上、左に）押すと、係止体１３０がスライド（図面上、左に移動）し解放状態から係止状態になり、柵部１２の回転が規制され、直立した状態で保持される。 <Rotation restricting means>
The safety fence 1 has rotation restricting means 13 .
As shown in FIG. 9 , the rotation restricting means 13 has a locking body 130 , a projecting plate 132 and a pull tab 133 .
The rotation restricting means 13 is provided on the connecting portion 111 . In the embodiment, the central connecting portion 111 of the three connecting portions 111 is provided with the connecting portion 111 , but any connecting portion 111 may be provided without being limited to this.
When the handle 133 is pulled to one side (to the right in the drawing), the locking body 130 slides (moves to the right in the drawing) and the projection plate 132 is released from the restraint, thereby changing from the locked state to the released state. The fence part 12 becomes free to rotate. That is, the fence part 12 can be closed.
As shown in FIGS. 1, 3 and 5, when the handle 133 is pushed to the other side (to the left in the drawing) with the fence 12 standing upright, the locking body 130 slides (moves to the left in the drawing). ), the released state is changed to the locked state, the rotation of the fence portion 12 is restricted, and the fence portion 12 is held in an upright state.

図１０に示す通り、回転規制手段１３は、弾性体１３４をさらに備えることができる。弾性体１３４は、一端が圧縮金具１３５に固定され、他端が係止体１３０に当たる様に、係止体１３０および引手１３３と平行方向に伸縮するように配置される。
弾性体１３４を備えることで、引手１３３を引かない限り、回転規制手段１３は係止状態を維持する。柵部１２を開閉する際に、引手１３３を引いて解放状態にしても、引手１３３を離すと弾性体１３４の弾性力によって、引手１３３および係止体１３０が左に押され（図１０）、回転規制手段１３は自動的に係止状態となる。柵部１２を直立させた際には、係止状態が維持され不意に解放状態となることがないため、意図せず柵部１２が回転自由になる危険がない。 As shown in FIG. 10 , the rotation restricting means 13 can further include an elastic body 134 . The elastic body 134 is arranged to extend and contract in a direction parallel to the locking body 130 and the pull tab 133 so that one end is fixed to the compression fitting 135 and the other end contacts the locking body 130 .
By providing the elastic body 134, the rotation restricting means 13 maintains the locked state unless the pull tab 133 is pulled. When the fence part 12 is opened and closed, even if the handle 133 is pulled to the released state, when the handle 133 is released, the elastic force of the elastic body 134 pushes the handle 133 and the locking body 130 to the left (FIG. 10). The rotation restricting means 13 is automatically locked. When the fence portion 12 is erected, the locked state is maintained and the released state does not occur unexpectedly, so there is no danger of the fence portion 12 becoming free to rotate.

実施例では、弾性体１３４としてコイルバネを用いているが、これに限らず、各種の鋼製バネや、空気バネ、油圧シリンダなど、弾性力を発揮できる器具であれば従来の種々の技術を用いることができる。 In the embodiment, a coil spring is used as the elastic body 134, but the present invention is not limited to this, and various conventional techniques can be used as long as they are instruments capable of exhibiting elastic force, such as various steel springs, air springs, and hydraulic cylinders. be able to.

図１０および図１１に示す通り、係止体１３０の張出板１３２側に、先端（図では左側）から徐々に肉厚が増加していく尖端部１３１を備えることもできる。
柵部１２を閉じた状態（倒した状態）から、柵部１２を開く（直立させる）方向に回転（正回転）させていくと、張出板１３２によって尖端部１３１がいわば踏まれるように押さえ付けられ、係止体１３０を右に押す力が働き、弾性体１３４が圧縮されて縮み、尖端部１３１が押し出される（図面上、右に移動する）ことで、柵部１２を開くことができる。張出板１３２が尖端部１３１から外れるまで回転すると、弾性体１３４によって尖端部１３１が左に押され、係止状態となる。 As shown in FIGS. 10 and 11, a sharp end portion 131 whose thickness gradually increases from the tip (left side in the figure) can be provided on the overhang plate 132 side of the locking body 130 .
When the fence portion 12 is rotated (rotated forward) in the direction of opening (standing upright) from the closed state (turned down state), the projecting plate 132 presses the pointed end portion 131 so as to be stepped on. A force is exerted to push the locking body 130 to the right, the elastic body 134 is compressed and shrunk, and the sharp end 131 is pushed out (moves to the right in the drawing), so that the fence 12 can be opened. . When the protruding plate 132 rotates until it is disengaged from the tip portion 131, the tip portion 131 is pushed to the left by the elastic body 134 to enter the locking state.

実施例では、柵部１２に対して張出板１３２が直角に備えられているが、これに限らず、６０度や１８０度に備えることもできる。その場合、係止体等１３０～１３５も、柵部１２が直立したときに、張出板１３２と同一平面上になるように備えることとなる。 In the embodiment, the projecting plate 132 is provided at right angles to the fence portion 12, but it is not limited to this and can be provided at 60 degrees or 180 degrees. In that case, the locking members 130 to 135 are also provided so as to be on the same plane as the projecting plate 132 when the fence portion 12 stands upright.

＜回転抑制手段＞
図１４、図１５および図１６に示す通り、回転抑制手段１４は、桁部１１と柵部１２に跨って備えられる。
回転抑制手段１４は、側面板１４１、抑制ネジ１４２、ガイド鋼１４３からなる。
側面板１４１は、柵部１２の側面に固定され、柵部１２とともに回転する。
抑制ネジ１４２は、ネジが設けられたネジ部と、その先端に設けられるノブを有しており、このノブを回すことによってネジ部も回転する。
ガイド鋼１４３には、案内溝が設けられており、抑制ネジ１４２のネジ部はこの案内溝に挿通される。つまり、抑制ネジの軌跡に応じた形状となっている。 <Rotation suppressing means>
As shown in FIGS. 14 , 15 and 16 , the rotation suppressing means 14 is provided across the girder portion 11 and the fence portion 12 .
The rotation suppressing means 14 is composed of a side plate 141 , a suppressing screw 142 and a guide steel 143 .
The side plate 141 is fixed to the side surface of the fence portion 12 and rotates together with the fence portion 12 .
The restraint screw 142 has a screw portion provided with a screw and a knob provided at the tip thereof, and the screw portion is also rotated by turning this knob.
A guide groove is provided in the guide steel 143, and the screw portion of the restraint screw 142 is inserted through this guide groove. That is, it has a shape corresponding to the trajectory of the restraining screw.

抑制ネジ１４２のネジ部の径は案内溝の幅よりも小さい寸法とされ、そのためネジ部は案内溝内をその形状に沿って移動することができる。側面板１４１には、内周ねじを有するネジ孔が設けられており、案内溝を通過した部分のネジ部はこのネジ孔と螺合している。したがって、抑制ネジ１４２を締め付けると、そのノブと側面板１４１によってガイド鋼１４３が挟まれ、側面板１４１がガイド鋼１４３に押さえつけられることから、側面板１４１が固定された柵部１２はその回転が抑制される。抑制ネジ１４２を緩めると、側面板１４１は何らの制約を受けないため、ネジ部が案内溝を自由に移動しながら、側面板１４１と柵部１２も回転することができる。 The diameter of the threaded portion of the restraining screw 142 is sized smaller than the width of the guide groove so that the threaded portion can move along its shape within the guide groove. The side plate 141 is provided with a threaded hole having an inner peripheral thread, and the threaded portion of the portion passing through the guide groove is screwed into this threaded hole. Therefore, when the restraining screw 142 is tightened, the guide steel 143 is sandwiched between the knob and the side plate 141, and the side plate 141 is pressed against the guide steel 143, so that the fence portion 12 to which the side plate 141 is fixed cannot rotate. Suppressed. When the restraining screw 142 is loosened, the side plate 141 is not restricted in any way, so that the side plate 141 and the fence 12 can also rotate while the threaded portion moves freely in the guide groove.

＜接続具＞
図６、図７および図８に示す通り、接続具１５をさらに備えることもできる。
安全柵１を床版３の両側に取り付けた際に、一方の柵部１２に接続具１５を備えることで、柵部１２を閉じた際に、該接続具１５を他方の安全柵１の柵部１２に嵌合させることで、二つの安全柵１が接続され、両柵部１２の回転が抑制される。つまり、テールゲートリフターの揺動にともなって柵部１２が跳ねたりするのを防ぐことができる。 <Connector>
A connector 15 may also be provided, as shown in FIGS.
When the safety fence 1 is attached to both sides of the floor slab 3, one fence part 12 is provided with the connector 15, so that when the fence part 12 is closed, the connector 15 can be connected to the other safety fence 1. By fitting to the portion 12, the two safety fences 1 are connected and the rotation of both fence portions 12 is suppressed. That is, it is possible to prevent the fence portion 12 from bouncing along with the swinging motion of the tailgate lifter.

図６に示す通り、柵部１２の高さが床版３の幅のほぼ半分である場合には、接続具１５を手摺１２４に備えることが好ましい。
図７に示す通り、柵部１２の高さが床版３の幅の半分より長い場合には、接続具１５を梁１２２に備えることが好ましい。 As shown in FIG. 6, when the height of the fence 12 is approximately half the width of the floor slab 3, it is preferable to provide the handrail 124 with the connector 15 .
As shown in FIG. 7, when the height of the fence part 12 is longer than half of the width of the floor slab 3, it is preferable to equip the beam 122 with the connector 15 .

接続具１５は、手摺１２４または梁１２２に嵌合するものだけでなく、図８に示す通り、巻き付ける縄のようなものでもよい。
実施例では、一方の安全柵１の手摺１２３と、他方の安全柵１の梁１２２にそれぞれ接続具１５を備え、そのほぼ中央部にバックル１５１等を有することで、接続するつくりとなっている。 The connector 15 is not limited to fitting to the handrail 124 or the beam 122, but may be a rope-like wrapping, as shown in FIG.
In the embodiment, the handrail 123 of one of the safety fences 1 and the beam 122 of the other safety fence 1 are each provided with a connecting tool 15, and a buckle 151 or the like is provided substantially in the center thereof to connect them. .
