on average.

The sweeper 1 consists of a cover 2 and Side walls 3 made of a suitable plastic or other suitable material. These are to accommodate Bearing or support members 4 are formed into which the pins 5 of the brush 6 engage. Are at each end of the brush Rollers 7 arranged in a known manner. The brush is helically wound and consists of a rod-like core 8 and tufts of bristles 9 on the core 8 the bolts are rigidly attached, and so are the tenons

The support members 4 engage in the openings 10 from above and are attached to the housing of the sweeper. These Support members 4 also serve to accommodate νcn brackets 11 in such a way that the handle 12 can engage in a coupling 13 located on the holder 11 and from the working position, in which he is at an angle from the ground

009887/1328

includes (see. Fig. 1), can pivot into an upward position in which the sweeper is lifted will.

For attaching the mounting bracket 11 to the support members 4, the latter are provided with a slide for guiding a guide jaw 15, which at each end of the bracket bracket is processed. The guide jaws 15 move along the guide in a horizontal direction. A pair of cams 16 on the guide jaw 15 engages the guide 17 of the support member 4 in such a way that, although not an actual Pivot pin is necessary, the handle 12 can be pivoted from one end position to the other about a pivot point, which is formed by the slide in connection with the cams 16 and their guide 17.

The individual accessories for receiving the pin 5 of the Brush 6 and the bracket 11 can be molded from plastic, but are preferably metal-plated in order to " to maintain good wear properties. The handle coupling has an inclined spring plate 19 into which the handle 12 engages and is held except when the spring plate is depressed at its upward end, to loosen the stem.

The trough-shaped dust or dirt container 20 are slightly narrower than half of the underside of the sweeper, however, they leave enough tree between their inner edges 21 so as not to obstruct the brush 6, if it is driven to sweep.

009887/13 28

Attachment members 22 are formed on these containers 20 and are connected to the container wall via flexible strips 24 _9, for example in film thickness, so that a joint is formed which allows the container 20 to pivot from the actuating position into the unloading position. This type of joint made of flexible plastic has the effect that the front wheels are driven with each thrust and that the film allows the wheels to be pressed firmly against the rollers 7.

The lugs 22 have a number of hangers 25, which are also attached to the lugs 22 by thin strips of fabric or foils are hinged. These hangers are provided with outwardly directed hump-like projections 27 which, if the hangers 25 inserted into the front or rear housing wall reach through the openings 29 to the outside and form a closure that can only be released by that the hangers are pushed back by a suitable device.

The containers 20 can be arranged on the outer walls by simply bending back the hangers 25, whereby these rest on the lugs 22 and the hangers are inserted into the openings, whereby the devices are fixed and are held.

At each end of this dirt container 20 is a recess 30 is provided on the flanges 31, which has an opening 32 for the axis 33 of the transport wheels 34 to pass through.

00988771328

The axles can be disengaged from the flanges Apply appropriate force when changing a wheel.

The dust or dirt container carry a wheel on each side, the arrangement of which is made so that when closed Both wheels 34 rest against the rollers 7 of the brush 6 in the dirt containers. The flexibility of the material from which the container 20 are designed is chosen so that the wheels automatically with the required force against the Drive rollers 7 are pressed, without the need for springs, as in the known designs.

The inner edges of both dirt containers are with combs provided with inwardly directed prongs which extend from a web 37 of the container 20. The tines run off conical, with the blunt ends resting on the web, while the pointed ends point towards the tufts of bristles 9. The shape and arrangement of the prongs is made so that in one direction of rotation of the brush the comb, from above is acted upon by the brush, the brush cleans by wiping off the swept material. The other comb however, at the same time promotes that which has already been stripped and collected during the movement in the other direction of rotation Material in the associated container.

009887/1328

When the operating direction is reversed, the sweeper turns Their effect is also changed and the material collected by the first-mentioned comb is placed in the associated container promoted.

These details in the arrangement ensure a very effective collection and deposit of dirt and other material, that moves through the combs / These combs are not, as usual, open links, but have a back and form a series of channels between the tines, increasing the upward depth, so that the dirt material removed from the brush by the one comb is brought onto the prongs and only with the reverse Movement of the same comb over the web 37 is emptied into the adjacent container.

It is necessary to normally keep the trough-shaped containers 20 in a horizontal position near the ground, however, the container must be able to pivot downward to empty the collected dirt or the like. to For this purpose, the containers 20 are loaded with a spring 40 which acts on IJreigabehebeln 41, which at their lower End has a retaining member 42 with a retraction bolt 43 which engages in one of the sleeves 44 on the containers 20 can. The release levers are in the extended position Position with opened dirt container because the end

of the holding member is only firmly connected to the container is after .es is inserted into the sleeve and the bolt 43 is retracted by engagement behind a projection 45 prevented.

The bracket 42 is hinged to the actuator 46 by a socking strip 47, while the the other end of the link 46 is connected to the release lever 41 via a weak strip 48 forming a hinge is. The lever 41 has pins 49 and engages in recesses 50 of the cover plate 51 of the housing, while the pins 49 are arranged in bearings 52 on the upper side of the housing 1.

The arrangement of this device is such that each lower support member 42 which this device on the container attached, permanently engages the container by engaging in the sleeve 44, but releasable by the interposition of a Link, sheet o. The like. If a return is required, while the vertically upwardly directed member 46 the Movement of the release lever 41 transmits to the corresponding container 20, so that äes with upward and downward movement Member 46 is opened or closed by pivoting the release lever 41 about the pin 49 of the corresponding container 20 will. The release lever, when the container is closed, is approximately parallel to the surface of the housing 1 are raised around the pins 49 when the containers are to be opened. The spring 40, which pulls between the release levers 41. Keeps the levers 41 directed inwards and the containers 20 closed.

If the free ends of the release lever are raised, the containers to which they are connected open.

It should be noted that every dirt or dust container has the same actuating device and these devices are determined in their position by the cover plate 51 are. The bearing journals 49 are held in this plate by the action of the spring 40.

The structure of the entire device, as well as the operating mechanism for the container, is extremely simple, each position being fixed by the spring 40.

The spring 40 also ensures that the wheels 34 in ■ have good contact with the drive rollers 7.

In the entire device, there is only a single spring between the two release or actuation levers 41 which hold the containers in the open or closed position and also in the closed position Position guarantee good contact between the baths and the drive rollers 7 of the brush 6.

Everywhere in the construction use is made of the aforementioned hangers or support members, which, although they are shaped as flat pieces, an intermediate Joint by arranging a strip that is thinner or weaker than adjacent areas

have so that the end part can be turned over in the direction of the remainder of the support member, but tries to stretch when it is in a socket or the like. is forced. This end part can go far enough excellent to lure against a corresponding or To push bumps in the socket, whereby it, as shown in particular in Fig. 2, is secured «,

From the description it can be seen that the carpet sweeper according to the invention has essential forteile First, because the housing that carries the brush is completely exposed when the container is open, so that the various protective parts that the machine has collected, can be easily removed and also an addition, repair or replacement of the brush without disassembly can be carried out"

In addition, secondly, by arranging the wheels 34 directly on the dirt containers 20, the advantage is achieved that no supports for the wheels other than the bearing journals 53 are to be provided. There is also no need for loading members, as are provided in the known machines, in order to keep the wheels in contact with the drive rollers of the brush. Since the wheels sinä mounted directly to the dirt containers in the present case _9, it is much easier to remove the brush, because the wheels have a sufficient distance from the drive rollers NaOH opening the container.

A further advantage is that the ridges in the manner of channels disposed on inner ien hand the dirt container, because the combs then ien as guide members for the Schnutsnatefin!, Which are conveyed in the containers, are used. However, more important is the arrangement of tines on the inner edges of the containers, which must not hinder cleaning Her container and must also be easy to clean itself.

That revenge ?, including part 53 is made of elastic material designed and can be slipped over the housing 1 as a buffer, un on the one hand the machine itself and on the other hand protect the items used by the machine be initiated.
