[Explanation]

In 1 to 4 is a first example Game of a handheld vacuum cleaner according to the invention shown, which consists essentially of a basic body 1 which, when cleaning, is outside on the upper edge of a slightly lowered gate window pane ( 4 ) can be hung, a hose 2 , which in cleaning operation leads through the gap of the slightly open door window into the interior of the motor vehicle and the free end of which functions as a suction nozzle, and one on the main body 1 hinged handle 3 with a fabric-elastic clamping or suspension 35 for springy grip on the upper edge of the door window pane and with a snap-in hook 36 for releasable locking in a locking slot 19 consists.

As with the known hand-held vacuum cleaner, the base body 1 a fan as essential functional components 127 to generate an air flow, an electric motor driving it in rotary motion 124 , a cable that feeds this motor with electrical energy, a filter that filters the sucked-in, contaminated exhaust air 122 , and a grating disc arranged at the outlet opening 15 on.

The basic body 1 has a cavity inside 11 with a partition 12 to hold the filter 122 on which a variety of distributed perforations 121 are provided for the passage of the sucked-in air. The filter 122 is upstream on one side of the partition 12 arranged in a prechamber while the engine 124 downstream on the other, the filter 122 opposite side of the partition 12 in a rear chamber over a U-shaped or yoke-like sheet metal strip 125 by means of screwing 126 is held by a screw at both ends 123 is fixed in the base body. The extracted air flows through the filter 122 the dirt particles or dust held therein are filtered out. The clean air that is essentially freed from pollution then flows through the perforations 121 the partition 12 and around the engine, thereby cooling the engine 124 by dissipating heat from it.

For cleaning a filter saturated with dirt 122 or to replace a used filter with a new filter, the accessibility of the same is achieved in that the housing of the base body 1 formed open at its end opposite the outlet opening and thus the grating disk and by a cap 14 with an internal thread 141 ( 2 ) that can be covered in an external thread that is complementary to it 131 of a nozzle 13 intervenes. For the purpose of cleaning or changing the filter inside 122 you only need the cap 14 from the main body 1 loosen what the filter 122 is made accessible from outside.

The grid disc 15 has deflecting blades extending parallel to one another 153 and openings formed therebetween 154 on. The deflection sheets 153 are to influence the wind direction obliquely to the axial direction of the base body 1 arranged. For easy detachable attachment of the grid disc 15 at the outlet opening of the base body 1 this has in the usual way two lugs formed on its circumference 151 and a detent tongue diametrically opposite this 152 on. The releasability of the grid disc 15 enables easier maintenance of the engine inside 124 , taking one to remove the grating disc 15 only needs the resilient locking tongue 152 to push down.

In a known manner, there is a receiving chamber for receiving the cable 16 formed in the base body with a cover plate 161 is closed.

For compacting the hose 2 is a circumferential groove 17 to hold the hose wrapped around the body 2 provided on both sides by a flange of the base body 1 is limited.

Over a neck 171 the hose communicates 2 with that of the partition 12 upstream antechamber of the cavity 11 in which the filter 11 is included.

The handle 3 is at one end about a storage 31 using a hinge pin 32 at a storage 18 on the main body 1 pivoted by the hinge pin 32 through the two ears 311 of storage 31 and an eyelet 181 of storage 18 is passed through. This allows the handle to be vertical, the axis of the body 1 enclosing center plane around the hinge pin 32 from the in 2 rest position shown in the in 4 shown working position can be pivoted out, in which he with the storage 31 opposite end at the upper edge of a slightly lowered door window pane (in 4 shown in dashed lines) attacks a motor vehicle, inside the hose 2 and the cable is inserted. To grip the upper edge of the door window pane, the handle is on its storage 31 opposite end with a lip-like elastic clamping 35 provided in the upper edge of the door window pane when the handle is swung out and in the working position 3 is clamped.

For releasably holding the handle 3 in its rest position is on its with the clamp 35 provided free end a snap hook 361 provided in a snap-in slot 19 on a tongue 191 of the basic body 1 is then snapped into place in a gap 36 is clamped. On storage 31 the barb-shaped snap hook goes at the opposite end 341 over a fabric-elastic web 34 into the clamp over.

To stabilize the in the circumferential groove 17 added to the main body 1 looped hose 2 has the handle 3 a yoke 33 , when the handle is at rest 3 almost to rest on the wrapped hose 2 comes (see 2 ).

How out 4 the handle becomes visible during operation 3 pivoted up and hung with its clamp on the dashed, slightly opened door window, over which the hose 2 and the cable is led into the interior of the motor vehicle. This ensures that all the load factors such as the unfiltered fine dust particles caused by the engine 124 generated noise, and the heat generated by this, are isolated by the only slightly opened door window, which has the consequence that a stress-free, favorable working environment for cleaning is created for the operator who remains in the motor vehicle.

The release of the snap hook from the snap slot 33 can be done simply by depressing the clamp 35 done with one finger.

5 to 8th illustrate a second embodiment of the invention, wherein the constituent components are numbered with the same reference numerals. The second embodiment differs from the first only in that the pivoting out of the handle 3 not in a vertical central plane, but in an approximately horizontal plane. Accordingly, the handle 3 around a vertical bearing axis 31 ' in a storage 18 ' (Eyelet 181 ' ) swiveling on the base body 1 stored. For immovable mounting in the axial direction of the bearing axis 31 ' this has a circumferential annular groove 311 ' , in the two mounting pins 32 ' penetrate, each through one in the eyelet 181 ' of storage 18 ' incorporated hole 182 ' through into the ring groove 311 ' are passed through, thereby preventing the handle from falling out of its storage.

It should be noted that in this second embodiment the clamping 35 does not matter to the bracket on the door window pane. It only facilitates the release of the snap hook 341 from the snap-in slot 19 ,

Here is the holder of the main body 1 on the door window through the snap hook 341 made.

The handle is in operation 3 released from its engagement and around the bearing axis 31 ' in a horizontal plane from its rest position in 6 in his working position in 8th swung out and there with its snap hook 341 hung at the top of the door window.

The ending has over the known handheld vacuum cleaners the following advantages:

• 1) With the retractable handle 2 The handheld vacuum cleaner according to the invention can, depending on requirements, both with a handle which is locked in the base body 2 used as a known hand-held vacuum cleaner as a movable whole in a known manner as well as when the base body is suspended from the outside of a door window 1 with his hose 2 used as a moving part in the car back and forth.
• 2) Thanks to the mode of operation according to the invention, in which the base body 1 held on the outside of a door window of a motor vehicle, all the stress factors such as the unfiltered fine dust particles, the noise generated by the engine, and the resulting waste heat are largely avoided, which ensures convenient cleaning work.
• 3) In comparison with the well-known hand vacuum cleaner, in which the entire body as a moving whole must be moved around by hand in the hand vacuum cleaner according to the invention only the hose is guided as a moving part, which makes the cleaning work considerably facilitated. It is also advantageous that with the hand-held vacuum cleaner according to the invention also the narrow, otherwise difficult to access corners can be easily cleaned are.
• 4) By looping the hose 2 around the main body 1 in cooperation with the stabilization of the yoke a flawless safe compacting of the handheld vacuum cleaner according to the invention is achieved.
