- the foot pedals 112, 114 are arranged so that a driver sitting on the driver's seat 102 can operate them without "changing places", the foot pedals 112, 114 preferably being out of reach for normal driving operation (with operation of the foot pedals 110a, 110b) to prevent inadvertent operation or to allow comfortable driving.
- the sweeping tool holder 39 comprises a rocker 120.
- This rocker 120 is pivotally mounted on the chassis 12 via a pivot bearing 122.
- the pivot bearing 122 defines a first pivot axis 124 (see, for example, in FIGS. 5 to 7) about which the rocker 120 and thus the sweeping tool holder 39 with the sweeping tool (the sweeping roller 38) relative to the chassis 12 is pivotable.
- the first pivot axis 124 is oriented parallel to a wheel axis of the rear wheel device 14 for the (main) sweeping roller 38. When the floor cleaning machine 10 rests on a flat surface 42, then the first pivot axis 124 is parallel to this base.
- the pivoting direction 126 is a clockwise direction with respect to a left side of the vehicle. Starting from the processing position (FIG. 7), the rocker 120 and thus the sweeping tool 38 can be pivoted in a pivoting direction 128 in order to reach the distance position.
- the pivoting direction 128 is an opposite direction to the pivoting direction 126.
- an actuating lever 130 via a pivot bearing 132 (see, for example, Figure 8) articulated.
- the pivot bearing 132 defines a pivoting of the actuating lever 130 about a second pivot axis 134.
- This second pivot axis 134 is parallel to the first pivot axis 124th
- the pivot bearing 132 is spaced from the pivot bearing 122.
- the operating lever 130 is formed as a foot pedal lever with the foot pedal 114. An operator can operate a foot operation of the operating lever 130 (a pivotal movement and a lateral movement as explained in more detail below).
- the actuating lever 130 is coupled via a web (a strut) 138 (mechanically) to the sweeping tool holder 39 and thereby to the rocker 120.
- the actuating lever 130 has an end portion 140, which faces away from the pivot bearing 122 (see FIGS. 5 to 7).
- This end portion 140 is outside the hood 88 and thereby before the
- the end region 140 is in particular positioned above the installation area 108.
- the web 138 is articulated to this end region via a pivot bearing 142 (compare, for example, FIGS. 5 to 7).
- the pivot bearing 142 defines a third pivot axis 144 about which the web 138 is pivotally hinged to the actuating lever 130.
- a tread element 146 of the foot pedal 114 At the end region 140 sits above the pivot bearing 142, a tread element 146 of the foot pedal 114.
- the web 138 is spaced from the pivot bearing 142 via a coupling device 148 to the rocker 120 (the sweeping tool holder 39) coupled.
- the coupling device 148 is designed in particular as a rotary-sliding bearing. In one embodiment, it comprises a recess 152, in particular in the form of an oblong hole on the web 138. This recess 152 is spaced from the pivot bearing 142 and spaced from a first end 154 and an opposite second end of the web 138.
- an engagement member 158 is arranged, in particular in the form of a pin, which is immersed in the recess 152 and is movable in this.
- the coupling device 148 allows both the pivotability of the rocker 120 (the sweeping tool holder 39) about the first pivot axis 124, as well as a translation displacement of the web 138 relative to the rocker 120 (that is, a relative displaceability of the engagement member 158 in the recess 152).
- the web 138 and the rocker 120 are further coupled to each other via a spring device 160.
- the spring device has a coupling point 162 on the web 138. This coupling point 162 lies in the region of the second end 156 of the web 138.
- the spring device 160 further has a coupling point 164 to the rocker 120. This coupling point 164 is spaced from the pivot bearing 122 and is located in the vicinity of the engagement element 158th
- the spring device 160 is arranged and designed so that in the spaced position of the sweeping tool holder 39, the spring device 160 is biased ( Figure 5) and endeavors to allow a relative movement of the web 138 to the rocker 120.
- the spring device 160 is or preferably comprises a tension spring 166, which is suspended in particular at the coupling points 162 and 164. With a bias of the tension spring 166 this tends to reduce the distance between the coupling points 162 and 164.
- the coupling point 162 of the spring device 160 on the web 138 is located on the base 42, when the floor cleaning machine 10 properly rests thereon, below the coupling point 164 of the spring device 160 on the rocker 120.
- the spring device 160 is arranged and configured to be positioned in front of the web 138 in the direction of the front end 18, with respect to the region of the web 138 with the recess 152.
- the web 138 has a corresponding hook element at the second end 156 in order to make this possible.
- the spring device 160 is further arranged in one embodiment at least approximately at the same height relative to the pad 42 as the pivot bearing 122 when the floor cleaning machine 10 is properly placed on the pad 42.
- the recess 152, the spring device 160 and the coupling points 162, 164 are arranged in a region 168 (FIGS. 1 to 3) which lies below the installation region 108.
- the installation area 108 covers this area 168 upwards.
- Disposed on the chassis 12 is a guide element 170 on which the actuating lever 130 is guided (for example, FIGS. 4 to 7; in FIGS. 8 to 11, the guide element 170 is removed).
- the guide element 170 lies behind the front wall 106 and is at least partially covered by the hood 88.
- the guide member 170 is spaced from the pivot bearing 122 and spaced from the end portion 140 of the rocker 120.
- the guide member 170 has a slot portion 172 through which the operating lever 130 is provided with a portion 174 which is interposed between the end portion 140 and the portion with which the operating lever 130 is hinged to the pivot bearing 122.
- the slot portion 172 forms a through opening to just that
- the slot area 172 includes a first area 176 and a second area 178 adjacent to the first area.
- the first area 176 and the second area 178 are each slot-shaped.
- the first region has an extension length Li (see FIG. 6) transversely to the first pivot axis 124.
- the second region 178 has a length L 2 in the same direction, the length L 2 being greater than the length Li.
- the first region 176 and the second region 178 have a common end 180 towards the bottom 124.
- a step 182 is formed on the slot region 172 during the transition from the first region 176 to the second region 178.
- An end 184 of the first region 176 opposite the end 180 at the step 182 forms a stop for the actuating lever 130.
- the actuating lever 130 abuts against the stop (end) 184 with its region 174 (see FIG. 5) , then another Pivot mobility of the actuating lever 130 upwards in one
- Pivoting direction of the pad 42 away (clockwise in Figure 5) locked.
- the actuating lever 130 is pivoted about the pivot bearing 132 on the chassis 12. He also has a transverse mobility (indicated in Figure 5 by an arrow with the reference numeral 186).
- the operating lever 130 is movable in a direction parallel to the first pivot axis 124.
- This transverse mobility of the operating lever 130 makes it possible to solve the distance position.
- the actuating lever 130 can thereby be transferred from the first region 176 into the second region 178. It can then be pivoted further upwards (from the base 42) in the second area 178. This makes it possible to reach the machining position (FIG. 7).
- FIG. 6 shows an intermediate position in which the actuating lever 130 moves in the second region 178 until the end position according to FIG. 7 is reached.
- the sweeping roller 38 has a height H ( Figure 1). This height H corresponds to the sweeping roller 38 in the case of a sweeping roller.
- the sweeping roller 38 comprises a bristle holder 188 (see FIG. 1) on which bristles 190 are seated. During a cleaning process in the bristles act with their tip or a region at the top of the pad 42. The height H (and thus the diameter) of the sweeping roller 38 is predetermined by a corresponding bristle length of the bristles 190th
- the bristles 190 wear during sweeping operation; This manifests itself in the fact that their length decreases.
- the height H (and thus the diameter) of the sweeping roller 38 thus decreases in the cleaning operation.
- the position of the operating lever 130 in the second machining position portion 178 of the sweeping roller 38 is determined by the height H of the sweeping roller 38. If the sweeping roller 38 has a smaller height H, then the portion 174 of the operating lever 130 rests against the guide member 170 and therewith at the second region 178 farther from the pad 42, since the rocker 120 can be pivoted in the pivoting direction 126 by a larger angle to the pad 42 toward.
- the pivotal position of the operating lever 130 on the guide element 170 and thereby the position of the region 174 in the second region 178 (in the processing position) is thus predetermined by the height H of the sweeping roller 38.
- the operating lever 130 is assigned a wear indicator 192.
- the wear indicator 192 is arranged as a scale on the hood 88 (the housing 88), namely on a housing area which covers the guide element 170.
- the wear indicator 192 ' is arranged as a scale directly on the guide member 170 when the guide member 170 is visible from the outside (the hood 88 then has, for example, a corresponding recess), so that the wear indicator 192' from the outside is visible.
- the sweeping roller 38 is located at least in a large portion below the chassis 12 and is also covered laterally by the cover 62. An operator of the floor cleaning machine 10 can therefore not directly from the outside recognize the height H or recognize the bristle wear. By looking at the wear indicator 192 or 192 ', when the machining position is provided on the positioning device 41, it also allows easy detection of the degree of bristle wear.
- the wear indicator 192 is arranged on a region 194 of the hood 88, which is in particular supported directly on the chassis 12. As a result, a relatively accurate wear indicator can be achieved and tolerances are minimized.
- the wear indicator 192 or 192 ' may be a quantitative indication and / or a qualitative indication.
- the quantitative display indicates, in particular, the bristle length or a measure of the bristle length.
- the qualitative indication indicates whether the sweeping roller 38 can still be used for a sweeping operation or not.
- the tillage machine 10 of the invention operates as follows:
- the operating lever 130 is positioned in the first area 176 of the guide element 170 (with its area 174) and bears against the stop 184. In this spaced position, the operating lever 130 can not be pivoted further upwardly away from the pad 42.
- the engagement member 158 on the rocker 120 abuts an upper end 196 of the recess 152. As a result, the pivoting mobility of the rocker 120 is locked with the sweeping tool 38 in the pivoting direction 126 and fixes the distance position.
- the spring device 160 is biased thereby; a spring force of the spring device 160 strives to reduce the distance between the coupling point 162 and the coupling point 164 in the distance position.
- An operator can bring the sweeping roller 39 into the processing position starting from this distance position. For this purpose, it acts and thereby moves the actuating lever 130 in the direction 186 such that the region 174 is guided from the first region 176 into the second region 178 (FIG. 6).
- a corresponding arrow 198 for the transverse mobility 186 is arranged in order to signal an operator just this "possibility of releasing" the locking of the distance position.
- the actuating element 130 is also pressed down to the pad 42 to allow release of the stop 184.
- the operator thus moves the actuating lever 130 with its region 174 from the first region 176 into the second region 178.
- the spring device contracts and this causes the web 138 to be displaced upward away from the support 42 (FIG. 6) ).
- This mobility is just about the recess 152 and in particular their training as a slot allows.
- the recess 152 thus shifts to the engagement element 158.
- This causes the actuation lever 130 to be displaced upward in the second area 178, thereby passing over the end 184 (FIG. 6).
- the angle of rotation depends on how high the height H of the sweeping roller 38 is and thus on the bristle length.
- the operating lever 130 pivots in the second region 178 upwards until the end position of the rocker 120 is reached by resting the sweeping roller 38 on the base 42.
- a corresponding end position corresponding to the processing position of the sweeping roller 38 is then shown, wherein in the exemplary embodiment shown there, the actuating lever 130 is pivoted to near an end of the second region 178 (opposite the end 180). This means a low height H or a strong bristle wear.
- the processing position shown in Figure 7 corresponds to a large deflection of the operating lever 130; this corresponds to a large wear of the sweeping roller 38.
- wear indicator 192 shows in the position shown in Figure 7 that the sweeping roller 38 "soon" must be replaced.
- the spring device 160 ensures that disengagement from the distance position according to FIG. 5 is also possible if the height H of the roller brush 38 is relatively high (there is no wear). If, starting from the distance position, the actuating lever 130 is moved in the transverse direction 186, then the spring device 160, in cooperation with the recess 152, ensures that the region 174 of the actuating lever 130 is moved over the step 182, that is, reaches a secure disengagement and also an accidental locking is prevented in a machining operation. If, starting from the processing position ( Figure 7), an operator wants to bring the sweeping roller 38 in the distance position, then he presses in a direction 200 on the tread 146 of the operating lever 130. The actuating lever 130 is then about the second pivot axis 134 in a
- Swivel direction 128 ( Figure 7) down to the pad 42 pivoted.
- the web 138 is moved downward and thereby the rocker 120 is pivoted away from the pad 42 by a pivoting movement in the direction 128.
- the area 174 of the operating lever 130 can be brought into the first area 176. After releasing the operating lever 130 by the Operator, the area 174 may abut against the end 184 so as to lock the distance position of the sweeping roller 38.
- the guide element 170 forms, with its slot region 172, a type of link for the region 174 of the actuating lever 130.
- the processing position of the sweeping roller 38 can be achieved or it can reach the distance position and lock.
- a wear indicator 192 can be formed in a simple manner by means of which an operator can recognize the wear of bristles 190 of the sweeping roller 38 without having to examine the sweeping roller 38 himself.
- the position of the portion 174 of the operating lever 130 on the guide member 170 in the processing position of the sweeping roller 38 characterizes the height H of the sweeping roller 38 and thus the bristle wear.
- the spring device 160 in particular in cooperation with the recess 152, ensures that even for a sweeping roller 38 without bristle wear the transition from the distance position to the processing position is achieved and there is no unintentional locking in the processing position. This results in a simple compact construction of the floor cleaning machine 10 by the described design of the positioning device 41. In particular, a movement space of the sweeping tool holder 39 with the rocker 120, which is achieved to achieve the distance position and the machining position, relatively small, so that the compact design easy way to realize.
- the distance position of the sweeping tool holder 39 is a maximum pivoting position 42 upwardly away from the base 42 and thus a limit position.
- the floor cleaning machine according to the invention is designed in particular as a sweeping machine and preferably as a ride-on sweeping machine. It is especially designed as a sweeping suction machine.
- a side brush 48 it is also possible for a side brush 48 to be brought into a processing position and into a distance position to the base 42 via a same positioning mechanism as described with reference to the positioning device 41.
