Attaching the log bank to the truck body today is simply done with bolts. Inserting and turning bolts is time consuming and cumbersome, especially when the threads become dirty and worn. German publication 1 0Θ9 2Θ4 discloses a locking system in which a flat spring is used, but here the purpose is to provide flexible movements for the pallet above the frame. The object of the present invention is to eliminate the above-mentioned drawback and to provide a new type of locking device which is fast, strong and safe.

The locking device according to the invention is characterized in that

t t I

_2_ 59956 One end of the flat spring can be fitted through the loop in the log bank as well as behind the stop in the car body beam and the other end can be resiliently tensioned away from the log bank to fit the locking piece between them. By means of the invention, the locking bank is now locked or removed simply and quickly. The locked locking device is also strong and secure due to its shape and construction.

A preferred embodiment of the invention is characterized in that the log bank has a limited space on the walls for the locking piece. In this way, the locking piece is positioned correctly and in place and cannot slip off.

Another embodiment of the invention is characterized in that the end of the flat spring resting on the stop has spikes which, when the spring is tensioned, press against the stop. In this way, the flat spring bites into the response and no slippage can occur in any direction.

The invention will now be described by way of example with reference to the accompanying drawings, in which

Fig. 1 shows a truck with a log bank.

Figures 2, 3 and 4 show the attachment of the locking device.

Fig. 5 shows another embodiment of the locking device.

Fig. 6 shows the flat spring of the locking device.

Fig. 7 shows a combination form of the locking device.

The locking device is used to lock the log bank 1 to the frame 3 of the truck 2. The locking device consists of a flat spring 4, the other end of which can be fitted through the loop 5 in the log bank 1 and under the stop in the frame beam 3 of the car 2. The other end of the flat spring 4 can be resiliently tensioned away from the log bank 1 to fit the locking piece 7 between them. In the embodiment shown in Figures 1-4, the log bank 1 has a limited space on the walls 6.9 for the locking piece 7. At the end of the flat spring 4 resting on the stop 6, there are spikes 10 which, when the spring is measured, press into the stop. The locking device also includes a tightening key 11 consisting of an elongate handle 12 with a transverse flat piece 13 at its end, which is rotated between the flat spring 4 and the log bank 1 for inserting or removing the locking piece 7.

The locking of the log bank 1 to the body 3 of the truck 2 takes place according to Figures 2-4 in the following manner. The leaf spring 4 is fitted through the loop 5 under the stop 6 as indicated by the arrows 14. between the leaf spring 4 and tukkipankan 1-fitted tightening tysavain 11, which is biased downwardly as shown by arrow. The log bank 1 is tightened to the frame 3. Between the log bank 1 and the flat spring 4, a locking piece 7 is arranged in the space in the log bank, delimited by the walls 6.9, which tightens in place when the tightening key is removed. The removal of the log bank 1 takes place in the reverse order.

In Fig. 5, a loop 5 is formed of lugs 14 and a detachable pin 15. In this case, the leaf spring 4 can be fitted in place from below with the pin 15 absent. This is necessary if the same flat spring 4 is used for two locking devices, as shown in Fig. 7. The locking piece 7 is then fitted to the center of the leaf spring 4, whereby both ends are tightened simultaneously.

It will be apparent to those skilled in the art that various embodiments of the invention may vary within the scope of the claims set forth below. Thus, the invention is not limited to locking the log bank. The locking device is also suitable for pallet systems. The frame 3 to which the log bank 1 or the like pallet is locked does not necessarily have to be the body of the truck, but it can also be the body of the trailer. For locking, various guides, walls and pins can also be added to the locking device to guide and ensure that the flat spring remains in place. Various adjustment pieces can also be placed between the flat spring 4 and the loop 5 attached to the log bank, with which the locking force can be adjusted.

According to the drawing, the loop 5 is in the log bank 1 and the stop 6 is in the frame beam 3. But equally well these can be located in the opposite direction.
