Attachment of a vacuum cleaner hose in the housing of a vacuum cleaner

The innovation relates to a piece of work equipment for fixed connection a vacuum cleaner hose in a vacuum cleaner housing, consisting of male and female parts and molded onto the male part resilient locking members with locking lugs.

Devices of this type are known. In the DE-OS 28 50 422 describes a device in which the lateral surfaces of the connection piece partially slotted in the axial direction and are provided with outwardly protruding locking lugs. Reach behind when the connection piece is inserted in the intake manifold the locking lugs with elastic bruising open the free end of the intake manifold wall. This creates a backup against unintentional pulling out of the connecting piece from the intake manifold.

This type of attachment prevents unintentional pulling out of the connecting piece. On the other hand, it also requires a great deal of effort, the suction hose after completion remove it from the vacuum cleaner again during the suction process. Damage to both the connection piece and the intake port are not to be met here.

Based on this state of the art, the innovation lies in The object of the invention is to create a device that prevents the vacuum cleaner hose from being unintentionally pulled out of the vacuum cleaner housing properly prevented and the intended removal the vacuum cleaner hose easily and without effort enables.

This object is achieved according to the invention in that laterally On the locking lugs, spherical opening surfaces are formed and in the mother part window-like locking openings are provided.

This achieves that the father's and mother's part existing connection can be locked and released again without any effort. By turning the one in the nut part On the male part to the right or left, the locking lugs snap into the window-like openings in the female part and thus secure your vacuum cleaner hose against being pulled out of the vacuum cleaner housing. Unlocking is also done by turning the male part to the right or left, whereby the innovation according to the invention The locking lugs are unscrewed to the side from the locking openings without any effort and then the male part with the attached Hose can be pulled out of the device housing. Damage to the connecting parts cannot occur here. An embodiment of the innovation is in the drawings and is described in more detail below. Show it:

FIG. 1 shows an individual part of a vacuum cleaner, partially in section; Figure 2 is an individual part of a vacuum cleaner hose partially

cut;
FIG. 3 shows a plan view in the direction of arrow according to FIG.

The exemplified work equipment for firmly connecting a vacuum cleaner hose in the housing of a vacuum cleaner consists of the nut part 1 and the male part 2. Resilient locking members 3 are formed on the male part 2, at the free ends of which latches are provided. The latching lugs h have spherical contact surfaces 6. Window-like locking openings 5 are arranged on the circumference of the nut part 1. In the working position, the male part 2 is inserted into the female part 1 and rotated to the right or left until the latching lugs k of the locking members snap into the latching openings 5. By turning the male part 2 to the left or right, the latching lugs k can be turned laterally out of the latching opening 5 again by turning the male part 2 and the male part 2 can be removed from the female part 1 provided on the vacuum cleaner housing.
