Definitions
- the invention relates to a sweeper with at least one removable feed brush attached to a front corner area of a Housing on a cantilever arm for feeding sweepings to a Broom is stored.
- Such sweepers are used in particular for cleaning Larger courtyard or hall areas, the sweepings by means of one or more sweeping rollers is picked up and in one Grass catcher is transported.
- the sweeper has an approximately 80 cm wide roller brush is simply pushed over the surface to be swept.
- the sweeper roller surrounds at the top and stores the grass collector for the dirt, are one or two rotating feed brushes (so-called side brushes) provided so that the dirt in the baseboard area or in Corner area along walls or curbs as well is picked up as these rotating side brushes remove the dirt Convey to the center and thus to the roller brush.
- This side brush are driven by a belt drive from the broom driven so that the side brushes a certain Need drive needed in such sweepers applied solely by the operator's pushing work must become.
- the invention is based on the object Sweeper to create a quick changeover between an operating position and a non-operating position the feed brush in a particularly simple and safe manner enables.
- the drive pinion is on the Axle bearing housing for the brush axis of the feed brush stored, so that no additional effort from the manufacturing effort is required. Due to the preferred training of Drive pinion with a compared to the height of the gear greater axial length is associated with the Height-adjustable brush axis achieves that even with larger ones Height adjustment stroke of the feed brush always constant Intervention conditions and thus a safe drive is given, because the drive belt and the drive sprocket itself removed feed brush as a structural unit in the cantilever arm of the Sweeper remains.
- a sweeper 1 is shown, at least a sweeping roller 2, which is lying on the floor Picks up sweepings and throws them into a grass catcher 3 promotes.
- the grass catcher is here by means of a grass catcher frame 3a on a sweeping roller 2 at least partially surrounding it Housing 4 stored.
- On the housing 4 or the catcher frame 3a is an inclined upward at approximately 30 ° Handle 5 attached to push the sweeper.
- About at a third of the length of the handle 5 are two lateral Swivel bearing 6 is provided, which is used to adjust the inclination of the Handle 5 serve.
- one or two feed brushes 7 are provided summarize the dirt in the lateral direction and the Feed sweeper roller 2.
- the sweeper roller (s) is / are over Wheels 8 arranged on the side of the housing 4 are supported and driven at the same time.
- the feed brush 7 has an upright Brush axis 10, which is mounted displaceably in the height direction is. This is done here by means of an axle bearing housing 13, in which the brush axis 10 is fitted with a clearance fit and thus is slidable in the upright direction.
- compression spring 14 is the Brush body of the feed brush 7 in the inoperative position from the floor surface completely or at least for the most part lifted. In the lower one, shown in dashed lines In contrast, the working position of the brush axis 10 protrudes considerably the plate-shaped axle bearing housing 13 down, so that the feed brush 7 with some pressure on the floor surface rests almost completely.
- the feed brush 7 points over the brush body a gear 11, which with a in the cantilever arm 9th mounted drive pinion 11a meshes by means of one of the Drive the sweeping roller 2 derived belt 12 the Drive feed brush 7.
- the gear 11 is coaxial with the feed brush 7 attached to the brush axis 10, which Gear 11 also integrally with the bracket body for the Bristles of the feed brush 7 can be formed. That with the Gear 11 meshing in the working position shown here Drive pinion 11a is attached to the axle pin 11c Axle bearing housing 13 for the brush axis 10 of the feed brush 7 stored.
- the axle bearing housing 13 can preferably be used as Injection molded part and be formed on the underside of the Cantilever arm 9 by means of several bushings 13a (see also FIG. 3) be releasably attached.
- Over the drive pinion 11a is preferred in one piece with this in turn as an injection molded part axially aligned pulley 11b provided to the in Manufacturing company of the drive of the sweeping roller 2 guided belt 12 is put around and thus pre-assembled.
- This belt 12 is driven by a drive pulley 12a, which in turn from one with one of the side wheels 8 interacting drive wheel 8a (see also FIG. 3) driven becomes.
- another type of drive such as a belt or Chain drive
- FIG. 2 there will now be another Element of the sweeper 1 or its feed brush adjustment described.
- locking device 15 schematically indicated by hatching provided that the brush axis 10 in the respective position fixed and jammed.
- the Locking device 15 by a brush axis 10 U-shaped encompassing lever or bracket formed by a spring is biased.
- the brush axis 10 in its Fixed height position. If the locking device 15 for example, is pressed with the foot, the Clamp released so that the brush axis 10 within of the encompassing lever in the axle bearing housing 13 in Height direction can move freely.
- a hemispherical push button 19 is provided, which can also be pressed with the foot, so that Feed roller 7 from the higher relief position according to FIG. 2 to move down into the lower working position. It is noted that with this shifting movement from above downward the locking device 15 is not self-locking, but the downward movement of the brush axis 10 enables. Here too, the toothing of the gear 11 slides while maintaining the meshing engagement along the Drive pinion 11a.
- the respective altitude of the working position can be with a Set height stop 20 shown in Fig. 2, the here is formed from a rotary knob 22 mounted in the cantilever arm 9, which has step-shaped steps 21 on the outer circumference.
- the feed brush 7 can under Apply pressure to the push button 19 only as far down adjust until the bottom of the push button 19 on here left stage 21 abuts.
- the feed brush 7 increasingly wears out by turning the rotary knob 22 here right level 21 or an intermediate level in agreement brought with the lower right edge of the push button 19 here be so that the brush axis 10 further down can be adjusted.
- this Gear 11 remains in engagement with the drive pinion 11a since the latter a height at least corresponding to the adjustment stroke (Axial length).
- this height stop 20 Tracking force and thus the sweeping intensity of the side brush to adjust.
- FIG. 3 is a bottom view of the cantilever arm 9 along the sectional plane X shown in Fig. 2.
- the remaining Reference numerals correspond to those described above Components.
- the End cap 30 along lateral, right-angled Sliding guides 31 can thus the entire assembly of the Feed roller 7 with its axis 10 together with gear 11 through a side slot 23 in the plate-shaped Remove the axle bearing housing 13 from the cantilever arm 9, the Belt 12 on the drive pinion 11a with integrated Pulley 11b remains.
- End cap 30 together with the components of the feed brush 7 results for transport, especially for the first delivery, a significantly reduced space requirement, so that for Sweepers with relatively wide sweeping rollers 2 and accordingly laterally projecting feed brushes 7, especially in the version with two feed brushes 7 on the right and left front corner area of the sweeper 1 still relatively small, compact packaging boxes used can be.
- the assembly is done by the Gear 11 / 11a and the remaining (i.e. no longer every time the feed brush 7 is removed straps 12 in easier, faster and safer Wise.
- the brush axis 10 instead of in through the side slot 23 from below the cantilever arm 9 inserted or by pulling down can be removed.
