Landing gear, Especially for vacuum cleaners

The innovation concerns a chassis, especially for vacuum cleaners, consisting of at least two running wheels and a frame with a support area and an approximately right-angled one Grip area as well as eilnem angled at its free ends open bracket for detachable connection of the chassis with a vacuum cleaner.

There are known vacuum cleaners that are releasably attached to a chassis are. It is attached using hooks that are located on the dirt container. This known type of attachment has the disadvantage that when driving over an uneven floor, over door sills or when cornering the vacuum cleaner from his Bracket releases.

The task of the innovation is to mount a vacuum cleaner on a chassis so that the disadvantages outlined above can be avoided and the suction cup is held securely and easily detachably on the chassis.

This object is achieved in that the elastically deformable Steel-made retaining bracket of the spatial shape of the one to be held Dirt vacuum corresponds to its fastening area and the Bracket has at least one loop-like bend. According to the innovation, the free ends of the bracket are bent in a U-shape. After further training the innovation is the distance between the ends of the bracket When the bracket is not clamped, it is larger than when the bracket is clamped. According to the innovation

grip in the installed state the free ends of the bracket in recordings in the landing gear.

The inventive bracket achieves that once due to the loop-like bend the spring deflection of the bracket is enlarged, whereby the bracket to detach the dirt container from the chassis is simply pushed over the edge of the container and on the other hand, the loop-like bend provides the necessary preload to keep the dirt container even when driving Can be held securely and easily over an uneven floor or in curves. It is advantageous when releasing the container from the chassis the loop-like bend as a handle. The U-shaped bent ends of the bracket prevent unintentional loosening of the bracket from the brackets in the chassis, ζ. B. by pushing the bracket sideways to the inside. Because the clear distance between the free ends of the bracket Larger without a clamped dirt container than with a clamped one Is dirt container, the mounted bracket is pretensioned so that it cannot come loose by itself and the Dirt container pressed against the chassis under pretension will.

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

Figure 1 shows a chassis without a dirt container; FIG. 2 shows a chassis with a dirt container; Figure 3 shows a detail A according to Figure 2 in plan view,

The chassis consists of a frame 1 with wheels 2 and 3 arranged on it. The support area h of the frame 1 serves as a receptacle for a cylindrical dirt container 5. A retaining bracket 7 is used as a fastening element. The retaining bracket 7 consists of wire and is bent in accordance with the radius of the dirt container 5. The free ends 8 and 9 of the bracket 5 are bent in a U-shape.

The clear distance between the ends 8 and 9 is not im installed state of the bracket 7 greater than in the clamped state. On the retaining bracket "7 there is a loop-like one on the side Bend 10 molded. The curve 10 provides the vote- voltage with which the container 5 is printed against the chassis 1 and the necessary spring deflection so that the retaining bracket 7 is pushed over the edge 11 of the container 5 to release the container 5 can be.

To attach the dirt container 5 to the chassis 1 is the U-shaped end 8 of the bracket 7 is suspended in a receptacle 12 in the chassis 1. Then the retaining bracket 7 is around the container 5 placed and the U-shaped end 9 suspended in a receptacle 13 in the chassis 1, so that the container 5 under front- voltage is pressed against the chassis 1. To release the dirt container 5, the retaining bracket 7 is over the edge of the container 11 pushed.
