ツトから離れて架橋体から遠ざかる場合橋板とその延長
部が静止位置に移動するのが好都合である。何となれば
そうしないと、危険な状態が生じることがあるし、特に
運転者が不注意の場合はなおさらであるからである。In the case of these bridges, it is advantageous for the bridge deck and its extension to move to a rest position when the vehicle loading and unloading leaves the pit and away from the bridge. If this is not done, a dangerous situation may occur, especially if the driver is careless.
発明が解決しようとする問題点 この発明の基本的課題は、初めに記載した架橋体を改良
して、前記の車両がピツトから離れると、確実に架橋体
がその静止位置に逆もどりするようにすることである。Problem to be Solved by the Invention The basic problem of the present invention is to improve the crosslinked body described at the beginning to ensure that the crosslinked body returns to its rest position when the vehicle is separated from the pit. That is.
問題点を解決するための手段 この発明によつて前記の架橋体のために、架橋体に接し
ている車両等に対する超音波装置（検知装置）を設け

い。In addition to capturing and recording the vehicle, the ultrasonic detection device can act on the control device for the bridge to return the bridge to the rest position. This is caused, for example, by lifting the bridge deck, retracting the extension, and lowering the bridge deck to the pit plane. It is, of course, necessary to provide the usual switching and control means for this, which are not individually the subject of this invention.

うに接続される。In special cases, two ultrasonic transmitters and two ultrasonic receivers can be used. Each of these can be provided on one side of the crosslinking device. These components use the constant width of each vehicle and start with the recognition that the ultrasonic device cannot react if there is a narrow object in front of the bridge that does not need to be captured. Connected so that no operation occurs.
更に、架橋体の制御を超音波装置と連結して、延長部が
せり出し又ははね上げたときにのみ超音波装置が接続さ
れるようにするのが有利である。Furthermore, it is advantageous to connect the control of the bridge to the ultrasonic device so that the ultrasonic device is connected only when the extension is raised or flipped up.

れる。Example A drawing showing an example will be described in more detail. The bridge plate 1 is supported at its rear end so as to swing about the shaft 2 along the pit 3 and above the rectangular parallelepiped notch of the pit 3. At the free end of the bridge deck 1, there is an extension part 4 that can be pulled out and retracted, and during the use of the bridge, the bridge deck 1 is placed on the cargo loading platform 5 of a vehicle or similar through this extension part. Supported. The extension 4 is slidably supported by a slider 6. The work cylinder 7 pulls out and pulls in.

に告知するように調整してある。The bridge plate 1 is closed at the front by an end plate 1 '. Behind the end plate 1 ', there are two ultrasonic devices 11 and 12.
It is fitted with a transmitter and a receiver in the usual manner. In order to mount these transmitters and receivers, the end plate 1'has a rupture in which the ultrasonic actuating member is placed. Of course, it also protects the device. These ultrasonic devices are arranged to be able to capture the vehicle with the platform 5 and yet to notify the control of the bridge as soon as the vehicle leaves the bridge.

止部材によつて確保される。When such an announcement is made by the two devices, the bridge plate 1 is first swung upward by the cylinder 10 by means of a control device known per se. Then, the extension 4 is completely retracted by the working cylinder 7, and then the bridge plate 1 is lowered to match the surface of the pit 3. Usually this final position of the bridge deck 1 is ensured by a stop member.

リミツトスイツチにしなければならない。The connection of the ultrasonic device occurs either with the actuation of the slider 6 or with the extension protruding to the position of FIG. It is convenient to perform the shutoff by a switch or the like. This switch must work in the rest position of the bridge 1. Therefore, there must be a limit switch that can be actuated by the bridge plate 1.

られる。The present invention can be sufficiently implemented even in the case of a crosslinked body having a tiltable extension. In that case, the extension in the working position is approximately in the plane of the bridge, and the extension in the rest position is almost vertically downward. Under these preconditions, the detection device is placed in front of the bridge deck so as to protect the extension in its rest position and to cover it behind it.
