Boiler vacuum cleaner with chassis

The innovation relates to a boiler vacuum cleaner with a releasably mounted chassis, the boiler with a support frame is connected to rollers and wherein the chassis consists of at least two wheels with a guide office with Cross bars νβ ^ μηαβη are.

■ _ Boiler vacuum cleaners have a very large, usually barrel-shaped, dirt container. For this reason, these vacuum cleaners are provided with a chassis. In the case of containers up to a content of 30 liters, a chassis consisting of a support frame with several rollers arranged on it is sufficient if the floor is level. In the case of uneven floors and / or for boiler vacuum cleaners with a larger dirt container, other chassis, such as a sack truck-like chassis, are used to move the vacuum cleaner.

The task of the innovation is to create a boiler vacuum cleaner of the generic type equipped with a chassis that is versatile

. is reversible and can be done by a layperson without much effort with the ^; Boiler vacuum cleaner can be connected.

This task is solved by the characteristic features of the Claim 1.

By the innovation according to the adapter and the bracket can be a simple 5-roller chassis by a layperson without any prior training A hand truck-like chassis can be converted in just a few simple steps will. Each boiler vacuum cleaner equipped in this way can be used by the user according to its location or purpose be provided with the correct landing gear.

This eliminates the cost of an additional chassis, because with just a few additional parts, every vacuum cleaner can be equipped with the appropriate chassis. Even the retrofitting an existing vacuum cleaner with a chassis lsi without, which is better suited for transport on uneven ground further possible. With the hook according to the innovation, the vacuum cleaner is securely but easily detachably connected to the chassis. The fitting piece connected to the support frame is replaced by additional Securing means held in place.

An embodiment of the innovation is shown in the drawings. and is described in more detail below. Show it:

Figure 1 the chassis with boiler in side view;

FIG. 2 shows the chassis with the boiler in a plan view;

Figure 3 shows a detail "A" according to Flg. 2;

FIG. 4 shows a detail "B" according to FIG. 2.

The chassis shown consists of a support frame 1 with rollers 2 for the boiler 3 and a guide bracket 4 with running wheels 5. The fitting piece 7 is detachably connected to the support frame 1. Connecting elements are two U-shaped brackets 8 which snap into corresponding holes 9 in the support frame 1 and in the fitting piece 7. In the fitting 7, two further holes 1t) are arranged, in which the free ends of the guide bracket 4 are held in a pluggable manner. The guide bracket 4 is fastened in the fitting 7 from the axis 11 for the running wheels 5. A hook 14 is fastened to the outer shell of the boiler 3 and can be brought into operative connection with the upper cross member 6. Resilient position securing devices 15 are integrally formed on the fitting piece 7 and engage in the support frame 1. If the chassis consisting of the support frame 1 and rollers 2 is to be converted into a sack truck-like chassis, the fitting piece 7 is first inserted into a corresponding recess in the support frame 1 until the position locks 15 snap over the support frame 1. Then the fitting piece 7 - as shown in FIG. 4 - is fastened to the support frame 1 with the clamps 8. ___

-it-Now the guide bracket * t is inserted into the openings j O in the adapter 7 and the axis 31 - as shown in Figure 3 - through the holes 12 in the adapter 7 and 13 in the guide bracket 4 and the wheels 5 on the axis 11 attached.
Finally, the boiler 3 is placed in the support frame 1, with the hook 1 * + In the upper cross member 6 engaging. Boiler 3, guide bracket 4 and support frame 1 are now a unit
tied together. Of course, a sack truck-like chassis according to the present invention can, if necessary, easily be converted into a simple chassis by a layman.
