【発明の詳細な説明】
本発明はトラクタとトレーラの連結するさいに，トレー
ラに設けられているキングビンプレートに関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a king bin plate provided on a trailer when a tractor and a trailer are connected.
トラクタとセミトレーラはトラクタ側に設けたカプラ上
にトレーラ側のキングビンプレートをのせる形で、キン
グビンプレートのキングビンをカプラに連結する。The tractor and semi-trailer are connected to the coupler by placing the trailer-side king-bin plate on the tractor-side coupler.
キングビンプレートは、従来ほとんど薄板にキングビン
を溶接付け（脱着式も一部あるが省略）するのが一般的
であるが、キングビンプレートの裏側補強材は軽量化の
為、強度上最少限の数にしている補強材のピッチ間隔が
広いためキングビングレートがカプラ上にのった場合、
補強材より外れたキングビンプレートはへこみがちとな
り、見かげ上カプラとの接触面積が多い様に見えながら
も、事実は補強材の下面の一部のみとなり、非常に小さ
い面積での接触に限られてくるので、接触面圧が非常に
高《なり、カブラ上面とキングビンプレートがキングビ
ンな中心として回動すると、焼付きを起し、互にむしれ
合い製品をいためてしまう。Conventionally, King Bin plates are usually made by welding the King Bin to a thin plate (although there are some removable types, this is omitted), but in order to reduce the weight, the reinforcement material on the back side of the King Bin plate is made with a minimum amount of strength. If the king plate is placed on the coupler because the pitch of the reinforcing material is wide,
The King Bin plate that comes off from the reinforcing material tends to dent, and although it appears that there is a large contact area with the coupler, in reality, the contact area is only a part of the bottom surface of the reinforcing material, and the contact is limited to a very small area. As a result, the contact surface pressure becomes very high, and when the top surface of the cover and the king-bin plate rotate about the king-bin center, seizing occurs and they tear each other, damaging the product.
従って本発明では、まず、キングビンプレートの裏側補
強材を極力軽量化を計りながら、補強材の骨の間隔を極
力多くし、キングビンプレートの変形を防ぎ、実質的な
接触面圧を下げるべく、ラチス状の（含ハニカム、又は
それに類似のもの）構造にすることを目的とし、従来の
問題点の解決を計ったものである。Therefore, in the present invention, firstly, while reducing the weight of the back side reinforcing material of the King Bin plate as much as possible, the distance between the bones of the reinforcing material is increased as much as possible to prevent deformation of the King Bin plate and to reduce the substantial contact surface pressure. The purpose is to create a lattice-like (including honeycomb or similar) structure, and is an attempt to solve the problems of the conventional method.
従来トラクメ１とトレーラ２の連結は、カプラ３とキン
グビン５とにより連結されカプラ３の上面は機械加工さ
れており、一般的には鋳鋼品なので裏側のリブも十分入
っており、剛性は大きい。Conventionally, the trailer 1 and the trailer 2 are connected by a coupler 3 and a king bin 5, and the upper surface of the coupler 3 is machined, and since it is generally made of cast steel, there are sufficient ribs on the back side, and the rigidity is high.
しかもカプラ３上に乗り連結されるキングビン５を溶接
付けしたキングビンプレート４は薄板材である。Furthermore, the king bin plate 4 to which the king bin 5 mounted on the coupler 3 and connected is welded is a thin plate material.
そしてこのキングビンプレート４の裏側のメーンレール
１３、補強材６．７．８は間隔を太き《とり、強度上有
効範囲にのみ設けられているのみで、キングビン５はメ
ーンレール１３、補強材６，７．８にかこまれ、この部
材より外れる位置になるほどキングビンプレート４は、
へこみ変形が起り易くなる。The main rail 13 and reinforcing materials 6, 7, 8 on the back side of the king bin plate 4 are spaced wide apart and are only provided within the effective range for strength. 6, 7.8, and the further the king bin plate 4 is located away from this member, the more
Indentation deformation is more likely to occur.
その状態を第４図．第５図に誇張して示しているわけで
あるが、この状態でキングビンプレート４がカプラ３上
にのった場合、補強材６．７．８の下面のキングビンプ
レート４がカプラ３の上面に接触する所のみしか、実質
的な接触をしていないことになる。The situation is shown in Figure 4. Although it is exaggerated in FIG. 5, when the kingbin plate 4 is placed on the coupler 3 in this state, the kingbin plate 4 on the lower surface of the reinforcing member 6.7.8 is placed on the coupler 3. Substantial contact is only made at the point where it contacts the top surface.
したがって上述のように、これでは接触面圧が非常に高
くなり、カプラ３とキングビンプレート４の面がむしれ
、問題が発生する。Therefore, as described above, the contact surface pressure becomes very high, and the surfaces of the coupler 3 and the king bin plate 4 are peeled off, causing a problem.
本発明は従来のトラブルを防止すべく、補強材６．７．
８の空間を（補強材６は省いても可）埋めるべく金属も
しくは非金属を用いて製造されたラチス状補強材９又は
下記実施例に示す補強材をキングビンプレート４の裏側
へ接着もしくは圧着等で組付ける。In order to prevent the conventional troubles, the present invention provides reinforcing materials 6.7.
8 (reinforcement material 6 may be omitted), a lattice-like reinforcement material 9 manufactured using metal or non-metal or a reinforcement material shown in the following example is glued or crimped to the back side of the king bin plate 4. Assemble with etc.
なお図中１２はカバープレートである。Note that 12 in the figure is a cover plate.
第９図では、ラチス状補強材９に代るハニカム状補強材
１０を示してあり、又第１０図に円筒状補強材１１で同
等の効果を得るように他の実施例を示したものである。FIG. 9 shows a honeycomb-shaped reinforcing material 10 in place of the lattice-shaped reinforcing material 9, and FIG. 10 shows another embodiment using a cylindrical reinforcing material 11 to obtain the same effect. be.
本発明はラチス状等の補強材９等を用いているため、極
めて薄い板厚で構成でき、且つ鉄より軽い材料を用いて
十分な圧縮力に耐え得ることが出来、ラチスの目を細か
くして、キングビンプレート４のへこみや変形をなくし
、実質面圧を下げることが可能となった。Since the present invention uses a reinforcing material 9 in the form of a lattice, etc., it can be constructed with an extremely thin plate, and it can withstand sufficient compressive force using a material lighter than iron, and the lattice has a fine mesh. As a result, it is possible to eliminate dents and deformation of the king bin plate 4, and to substantially lower the surface pressure.
なお本発明のキングビンプレートの寿命をより長く保つ
ためにラチス状にかこまれた空間の下側のキングビンプ

に役立つ効果が得られる。In order to maintain a longer service life of the king bin plate of the present invention, small holes 14 are provided in the king bin plate 4 at the bottom of the space surrounded by the lattice, and semicircular holes 15 are provided at the bottom of the lattice wall. By filling the lattice-like reinforcing material 9 with grease, the king-bin plate 4 and coupler 3 are always
Grease flows on the surface, improving lubricity and helping prevent galling.

しめ長期使用に耐え得る等の効果がある。As mentioned above, the present invention prevents deformation of the king-bin plate and improves the substantial surface contact with the coupler by providing a lattice-like reinforcing material or a reinforcing material having an equivalent effect on the back side of the king-bin plate of the trailer. This has the effect of reducing surface pressure, preventing mutual gnawing and peeling, and improving durability to withstand long-term use.
