Description

本発明は、貨物自動車に搭載され、荷物の積み降ろしに使用される荷受台昇降装置に関し、特にこの昇降装置に組付けられたリヤバンパを有する突入防止装置に関する。   The present invention relates to a load receiving table lifting device mounted on a truck and used for loading and unloading of a load, and more particularly to a rush preventing device having a rear bumper assembled to the lifting device.

荷受台を起立格納する荷受台昇降装置には、その昇降装置が取り付けられる車両の突入防止装置を兼用したものが提供されている(例えば、下記特許文献1参照。)。具体的にいえば、この従来例では、荷受台を昇降させる左右一対の各昇降アームにブラケットを介在させて支持されたリヤバンパが設けられている。このリヤバンパは上記昇降アームの昇降動作に伴って昇降されるようになっており、車両の走行時などの荷受台が起立格納された場合には、突入防止としての機能が発揮されるように当該リヤバンパは車幅方向に配置された状態で荷受台昇降装置に支持されていた。   As the load receiving table lifting device for standingly storing the load receiving table, a device that also serves as a vehicle entry prevention device to which the lifting device is attached is provided (for example, see Patent Document 1 below). Specifically, in this conventional example, a rear bumper is provided that is supported by a pair of left and right lifting arms that lift and lower the load receiving table with a bracket interposed therebetween. The rear bumper is raised and lowered with the raising and lowering operation of the raising and lowering arm. When the load receiving stand is stood and stored when the vehicle is running, the rear bumper is The rear bumper was supported by the load receiving platform lifting device in a state of being arranged in the vehicle width direction.

特開平10−6893号公報(第4〜5頁、第5図)Japanese Patent Laid-Open No. 10-6893 (pages 4-5, FIG. 5)

ところで、上記のような従来例における荷受台昇降装置では、荷受台は荷箱と同じ幅であり、リヤバンパは相応の十分な距離をおいて設けられた左右の上記ブラケットによって支持されていた。しかしながら、例えば荷箱の幅の半幅のコンパクトな荷受台を使用する荷受台昇降装置の場合、荷受台の幅寸法とは無関係に所定長さ寸法以上のリヤバンパを用いるように法令によって定められていることから、荷受台の幅寸法以上のリヤバンパを設けることが要求される。それ故、単一のリヤバンパを荷受台昇降装置に組付ける場合では、上記ブラケットによるリヤバンパの支持部分から離れた箇所に後方から車両が衝突したときにその衝突によってリヤバンパが折れ曲がり、当該バンパの本来的な突入防止機能を果たせないおそれがあった。
一方、リヤバンパ自体の剛性を高めることにより、車両衝突時にリヤバンパが折れ曲がるのを防ぐことが考えられる。しかし、この場合、剛性を高めるために、リヤバンパの重量を増加させたり、この重量増加に伴いブラケット等の機械的強度を向上させたりすることなどが必要となり、結果としてコストアップなどに直結して得策ではない。特に、軽量化や低コスト化が求められる幅狭タイプの荷受台昇降装置では大きな問題となる。
By the way, in the conventional load receiving platform lifting device as described above, the load receiving platform has the same width as the load box, and the rear bumper is supported by the left and right brackets provided at a suitable distance. However, for example, in the case of a loading platform lifting device using a compact loading platform having a half width of the packing box, it is stipulated by law that a rear bumper having a predetermined length or more is used regardless of the width size of the loading platform. For this reason, it is required to provide a rear bumper that is larger than the width dimension of the load receiving platform. Therefore, in the case of assembling a single rear bumper to the load receiving platform lifting device, when the vehicle collides from the rear at a position away from the support portion of the rear bumper by the bracket, the rear bumper bends due to the collision, and the original bumper There was a risk that it would not be able to perform its proper entry prevention function.
On the other hand, it is conceivable to prevent the rear bumper from being bent during a vehicle collision by increasing the rigidity of the rear bumper itself. However, in this case, in order to increase the rigidity, it is necessary to increase the weight of the rear bumper, and to increase the mechanical strength of the bracket etc. with this increase in weight, resulting in a direct increase in cost. It's not a good idea. In particular, it becomes a big problem in a narrow-type load receiving table lifting device that requires weight reduction and cost reduction.

上記のような従来の問題点に鑑み、本発明は、荷受台の幅方向寸法以上の単一のリヤバンパの場合でも、リヤバンパの剛性を大きくすることのない軽量でコスト安価な荷受台昇降装置の突入防止装置を提供することを目的とする。   In view of the above-described conventional problems, the present invention provides a lightweight and inexpensive load receiving base lifting device that does not increase the rigidity of the rear bumper even in the case of a single rear bumper that is larger than the width direction dimension of the load receiving stand. An object is to provide a rush prevention device.

また、上記荷受台昇降装置の突入防止装置において、前記リヤバンパは、一端部側が前記支持部を介在させて前記昇降アームに取り付けられるとともに、前記受部材が、そのリヤバンパの他端部側を受け止め可能に設けられてもよい。
この場合、上記受部材は車両衝突時にリヤバンパの他端部側を受け止め支持することとなり、リヤバンパ自体の剛性を大きくせずに突入防止機能を適切に発揮させることができる。
Further, in the intrusion preventing device for the load receiving platform elevating device, the rear bumper is attached to the elevating arm at one end side with the support portion interposed therebetween, and the receiving member can receive the other end side of the rear bumper. May be provided.
In this case, the receiving member receives and supports the other end side of the rear bumper at the time of a vehicle collision, so that the entry preventing function can be appropriately exhibited without increasing the rigidity of the rear bumper itself.

また、上記荷受台昇降装置の突入防止装置において、前記リヤバンパは、中央部が前記支持部を介在させて前記昇降アームに取り付けられるとともに、前記受部材が、そのリヤバンパの左右の各端部を受け止め可能に設けられてもよい。
この場合、上記受部材は車両衝突時にリヤバンパの左右の各端部を受け止め支持することとなり、リヤバンパ自体の剛性を大きくせずに突入防止機能を適切に発揮させることができる。

Each fixing member 13 is a member for fixing the step 7 to the mounting frame 5d, and its base is welded to the frame 5d. Further, the plate 7 a (FIG. 3) of step 7 is connected to the front end portion side of each fixing member 13 through an attachment angle 14. Further, a pipe 7b (FIG. 3) is attached to the plate 7a on the rear and side sides of the vehicle body.

以上のように構成された本実施形態の突入防止装置Bでは、支持プレート11を介在させてリヤバンパ10の一端部側を下アーム5cに支持させている。また、リヤバンパ10の他端部側を受け止め可能に構成された受部材12を当該リヤバンパ10の他端部側の近接位置に設けている。これにより、リヤバンパ10での支持プレート(支持部)11から離れた箇所(車体左側)に後方車両が衝突したときでも、わずかに弾性変形したリヤバンパ10を受部材12が確実に支持することができ、後方車両の衝突時でのリヤバンパ10に対する支持剛性を確保することができる。この結果、上記従来例と異なり、リヤバンパ自体の剛性を大きくすることなく、突入防止装置Bの突入防止機能を適切に発揮させることができる。しかも、リヤバンパ10の剛性を大きくしていないのでリヤバンパ自体の重量やコストも増大せず、特に、軽量化や低コスト化が求められる幅狭タイプの荷受台昇降装置3に好適な軽量でコスト安価な突入防止装置を容易に構成することができる。   In the intrusion prevention device B of the present embodiment configured as described above, one end of the rear bumper 10 is supported by the lower arm 5c with the support plate 11 interposed. In addition, a receiving member 12 configured to receive the other end side of the rear bumper 10 is provided at a close position on the other end side of the rear bumper 10. As a result, even when the rear vehicle collides with a position (left side of the vehicle body) away from the support plate (support portion) 11 in the rear bumper 10, the receiving member 12 can reliably support the rear bumper 10 that has been slightly elastically deformed. Thus, it is possible to ensure the support rigidity for the rear bumper 10 when the rear vehicle collides. As a result, unlike the conventional example, the rush preventing function of the rush preventing device B can be appropriately exhibited without increasing the rigidity of the rear bumper itself. In addition, since the rigidity of the rear bumper 10 is not increased, the weight and cost of the rear bumper itself are not increased, and in particular, the light weight and the low cost are suitable for the narrow type load receiving platform lifting / lowering device 3 that is required to be reduced in weight and cost. Therefore, it is possible to easily configure a rush prevention device.

また、本実施形態では、受部材12の基部が固定部材13を介して取付フレーム5dに連結されているので、突入防止装置Bを荷受台昇降装置3に部品の状態で完全に一体化してユニット化したものとすることができ、当該突入防止装置Bと荷受台昇降装置3を個別に車体1へ取付けすることなく車体1への組付け作業を簡単化することができる。さらに、受部材12がステップ7用の上記固定部材13に固定されているので、この固定部材13を受部材12用の固定部材と兼用させることができ、突入防止装置Bの部品点数を削減して、低コスト化を容易に行うことができる。   In the present embodiment, since the base of the receiving member 12 is connected to the mounting frame 5d via the fixing member 13, the rush prevention device B is completely integrated with the load receiving table lifting device 3 in the state of parts. Assembling work to the vehicle body 1 can be simplified without individually attaching the rush prevention device B and the load receiving table lifting device 3 to the vehicle body 1. Further, since the receiving member 12 is fixed to the fixing member 13 for step 7, this fixing member 13 can be used also as the fixing member for the receiving member 12, and the number of parts of the inrush prevention device B can be reduced. Thus, cost reduction can be easily performed.
