Device for loading and unloading a container onto a Transport vehicle,

The disadvantages that existed in the case of transfers of movable containers (commonly referred to as "container" known) from the arrival station or port to the place of residence the individual recipient encounters. These disadvantages are due in particular to the fact that, in general, the transport vehicle through each container not only for the time required for the outward and return journey, but also above all for the time required to unload and load the container is taken · This fact apparently affects considerably on the investment and thus on the transport costs

It viurde already tried to make the container from the vehicle independently, but the results of this monitoring are totally unsatisfactory · So ivurde tried U9t \ container with its own,

■ Normally operated telescopic legs can be seen · This solution However, there are major disadvantages

| - primarily the width of the vehicle during transport d ^ m container magnification ert is yor all "

- in the second place will be sub simultaneous undressing and Pushing in the telescopic leg «Several people are required and the time required for this is relatively large, This is detrimental to the speed of loading operations affects

With other solutions, the power of the drive motor of the Motor vehicle used to actuate the legs of the container In this case the devices are considerably elaborate and expensive after auxiliary drives and hydraulic pumps and pistons and the like are required, these solutions can also be used were practically unable to enforce

The object of the invention is to make up for the majority of the stoppage of the transport vehicle while the container is being loaded and unloaded and the independent use of the vehicle for other transports while the container is idle « allow·

Another object of the invention is the container in the absence of To arrange transport vehicles self-supporting and in such a position, daft they without the help of sweeter lifting means and the like. can be quickly transferred to a relevant vehicle.

The device shown in the drawing essentially comprises an auxiliary frame 1 "with four legs and a support frame 12" which is attached to the chassis of a vehicle 13 b "w, forms part of the same. The two rear legs of the auxiliary frame * are telescopic legs. , the upper part 2 of which is fastened to the frame 1 by means of stiffening struts 3 and the lower part 32 of which can be axially pushed in and out Bearings 6 and 7 is rotatable about its axis. The middle part of the shaft 5 is provided with white bearing tubes 8 and 9 which are spaced apart from one another and which carry a pin 10, the axis of which runs parallel to the axis of the shaft S and around which a roller 11 is freely rotatable. The axes of the shaft S and the pin 10 lie in a plane »which leads through the achaae of the legs 4. The roller 11 is to "determined in the manner explained below" it a central guide 14 susemmensuarbeiten "the mm in the Mittellftngsaehse support frame 12 is fixed and of a U-iron 15" there is to be open at the top, and a guide channel 14 forms "in the cylindrical guide pins 16 can engage, the λπ cross members 17 of the subframe * 1 are attached and protrude from this in the middle level below.

Each of the front legs 4 of the auxiliary «frame · l» as said

A pin 19 is articulated to the corresponding leg 4 and is displaceable at its other end in a straight guide 21 by means of a pin 20. A pivoting hook 22 can hold the pin 20 firmly at one end of the straight guide 21 "The hooks 22 corresponding to the two legs 4 are fastened to a shaft 24 that can rotate, among other things. By rotating this shaft 24, the two hooks 22 can be raised or lowered at the same time in order to release or “hold” the corresponding two pins 20 ends • ine roller bearings 27, "calibration" of the shaft 5 is parallel "to the roll · 11, but away from her 1st" a spring 28 is hooked at one end into a tab · 29 of the frame 1 and with its other end is attached to the corrugation S, facilitates the transition of the front leg from its horizontally folded position (see Fig. 13) into the vertical cage in preparation for the locking of the pegs 20 on the part of the hooks 22 '

The subframe 1 forms the support structure for the container C, which is thus automatic with respect to the vehicle 13 on the part of the rear telescopic legs 2 and the one placed in a vertical position front legs 4 under-attttzt. Both the subframe 1 as well as the legs 2 and 4 are dimensioned in such a way that they carry the intended ultimate load of the container with the desired security can carry.

On the support frame 12 provided on the vehicle 13 there are two Sliding surfaces 35 present on which the relative movement between the U banks imitate 1 and the Kalmen 12 rolls 36 of the aid

If one now wants to move the container from the place where it is unloaded was to be transported to another location, then a vehicle 13 »is used on the chassis of which a support frame is used 12 is attached »which is with respect to the roadway on a Height is located which corresponds to that of the lower side of the auxiliary frame 1 substantially. The vehicle is driven under the subframe 1 in reverse direction as shown in FIG. 3, the rear end of the vehicle frame and the support frame * 12 attached to it first come into contact with the rollers 36 on the auxiliary frame 1, which supports the container · In this way, thanks to the flexibility of the suspension of the vehicle, the front end of the subframe is raised the front legs 4 are lifted off the road surface · Del The support frame then slides further backwards of the vehicle 12 under the subframe 1 in contact with the same During this sliding movement the mutual alignment is thereby made sure that the pins 16 gradually into the FOhrui Enter a channel 14, while the rollers 36 on the guides * slide flat 35 and the front legs 4 are relieved
