"Loading ramp"

Usually in supermarkets or the like. Stack of containers loaded onto trolleys to display bakery products such as bread, cakes, rolls and the like place. These trolleys are usually loaded in the bakery, each trolley with a stack Containers for bread or other bakery products. The loaded containers and carts then become ordinary transported to supermarkets by vans or trucks.

Often times, the need arises to load or unload the trolleys onto or off trucks without using them a lifting platform or an elevator-like swiveling one The loading ramp according to the invention is particularly suitable for these cases. A feature of this ramp is that it is easy to carry, picked up by a truck and conveniently stowed under the vehicle body, for example when not in use.

The novel loading ramp, as it is described below, makes it possible that the trolleys or trolleys loaded onto the trucks or unloaded from the trucks, with the containers in the stacks from the truck be held in a vertical, stacked position so that the stacks do not tend to tip over at the front.

The loading ramp according to the invention also proves itself when loading and unloading racks or racks onto trucks is useful and advantageous, the contents in no way having any tendency to fall out of these receptacles. Such racks carry, for example, a stack or a series of bowls or stairs in a normally horizontal position, like this that the goods located in these stairs are accessible. In the loading ramp according to the invention, the stairs assume a horizontal position when they are loaded onto the truck or be unloaded by him so that they or the contents cannot fall out of the racks.

The loading ramp according to the invention described below has two outer grooves and two inner grooves for the wheels or swivel castors of the above-mentioned transport trolleys, or the bases of the above-mentioned racks. The one channel— pair is arranged with respect to the other pair inside, and the outer gutters are raised above the inner gutters. The new loading ramp therefore actually has two inclined ones Levels of two channels each, one of which is above the other.

The rear swivel castors of the transport trolley or the Frame bases are spaced apart from one another in such a way that they engage in the inner, lower grooves of the loading ramp, while the front swivel castors of the transport cart are further apart, so far that they are in the outer, Engage in the upper rear of the loading ramp. That's why the larger spaced front castors of

the outer, upper two separate channels while the smaller spaced rear castors are guided by the inner, lower two separate channels.

If the transport trolley or the rack base is in this Way is engaged with the new loading ramp, the Containers carried by the transport cart individually in horizontal planes held, namely a container vertical above the other, and the stairs or bowls that are in the corresponding one Frame are carried, are arranged in the same way in horizontal planes, .so that the ones located in them Load does not tend to overflow over the edges of the containers or to fall out of the containers.

An embodiment of the subject matter of the invention is shown in of the drawing to which the following drawing relates. In the drawing show:

FIG. 1 shows a perspective view of the invention Loader leaning against the back of a truck is,

FIG. 2 is a perspective rear view drawn in dashed lines a container, carried on a transport trolley,

Figure 3 is a partial sectional view of the one located on the loading ramp Transpox'twägelchens, along the line 3-3 in Figure 2 and

FIG. 4 shows a rear view of the small transport trolley essentially along the line kh in FIG.

As can be seen from Figure 1, the novel loading ramp iO can be arranged at the rear end of a truck 12 so that it is one of. the loading area of the truck forms an inclined construction leading to the ground. As can be seen from FIGS. 1, 2 and 3, the loading station construction has a first pair of inclined channels 1h and 20.

909885/02 77

The grooves 1h and 20 form the outer and upper grooves of the ramp and are separated from one another at a distance. The loading ramp also has a second pair of channels 16, 18 which is arranged on the inside with respect to the channels Ik and 20, as can be seen from the drawing, and is shifted downward from the channels Ik and 20.

The lower, inner grooves 16 and 18 are held at a certain distance from one another and parallel to one another, for example by a middle plate 2k. This sheet 2k is either welded to the lower channels or attached to them in some other way or forms a unit with them. The upper, outer gutters Ik and 20 are supported above the lower, inner gutters 16 and 18, for example with the aid of a plurality of upright supports 25 and inclined stiffening elements 26 which are welded to the gutters or are otherwise attached to them.

As a result, the loading ramp has a first, inclined one Forms two-channel level, which consists of the channels 14 and 20 and a second, inclined two-channel level with a distance below the first level and parallel to it, consisting of the inner, lower channels 16 and 18.

A stack of containers 30 can be loaded onto a truck 12 in that the stack is placed, for example, on a transport cart 32 (FIGS. 2, 3 »k) and this is then rolled up the ramp. The cart has a floor or a base and is supported on the inclined ramp (Figure 1) so that the base or the base lies horizontally so that the containers of the stack 30 are carried in an approximately vertical position, as shown in the drawing can be seen, the individual containers of the stack are arranged horizontally when the cart is driven up or down the inclined ramp.

It follows that the novel ramp is a convenient means of loading onto transport trolleys or in scaffolding represents carried stacks of containers on truck 12, or for unloading the stacks from the truck without danger is that the stack from being raided, or that the contents of the individual containers fall out.

As can be seen from FIGS. 2, 3 and k , the transport cart 32 has a base body or base. A first pair of rollers 32 and 38 are attached to the front end of the body, while a second pair of rollers AtO and ^ 2 are attached to the rear end of the body. The rollers 36 and 38 are at a greater distance from one another than the rollers ^ O and 42, so that when the trolley moves up or down the ramp 10, as shown in FIG. 1, the front rollers 36 and 38 into the outer, upper grooves lh and 20 can engage, while the rear rollers hO and k2 with the lower, inner grooves l6 and 18 can be brought into engagement. The stack of containers 30 is then carried in the desired upright position, as shown in FIG. 1, when the transport trolley is driven up or down the ramp.

The scaffolding or shelves mentioned above come with one each Base body or base equipped, which has a pair of front rollers and a pair of rear rollers, similar to the base - body or bottom of the cart shown in Figure 2. In these scaffolding, the front rollers face in a similar manner a greater distance from one another than the rear rollers, so that the desired engagement between the rollers and the troughs the ramp is reached.

According to the invention there is accordingly an improved loading ramp created that can be easily taken in a truck and when loading or unloading each, described in the above Stacking containers on trucks or from trucks is very advantageous.
