Definitions

  • the invention relates to a high-pressure cleaning device a base frame on which two spaced apart on an axis Wheels are arranged and the one in its front Area at a distance from the axis of a support part for support on the floor.
  • Such housings for high pressure cleaning devices are in various embodiments have become known. You point a push handle, with the aim that the pressure washer is easy to move.
  • the known push bars have the disadvantage that they not from an injection molded frame-like plastic part exist and therefore only with high manufacturing costs are to be produced. It is known here to push the push bar e.g. to be made from a metal part, from a combined one To manufacture metal-plastic part and the like.
  • the invention is therefore based on the object High pressure cleaning device with removable push handle at the entrance mentioned type so that the push handle as shell-like part easily detachable with the basic housing of the High pressure cleaning device can be connected and that High-pressure cleaning device with the push handle removed has a relatively low height.
  • the invention is thereby characterized in that the push bar from a shell-like Plastic part with two opposite and parallel side cheeks are formed, which Sidewalls in their upper area by a common, the cross member connecting the side bolsters connected to each other are.
  • connection level between the Push bar and the main housing of the high-pressure cleaning device is formed as close as possible to the basic housing. This measure leads to the fact that the basic housing is removed when the push handle is removed has a relatively low overall height.
  • connection level between the push bar and the support level of the basic housing lies underneath the removable hood for the basic housing, because this ensures an optimally low overall height of the high-pressure cleaning device reached with the push handle removed.
  • the easy disassembly of the push handle has it Another advantage that the rest of the assembly Parts of the high-pressure cleaning device, namely in particular the Bracket of the motor pump unit on the basic housing, light become accessible.
  • the front, middle foot bearing is height adjustable, so that Motor pump unit by the setting on the foot side Bearing can be pivoted, the pivot axis in Area of the rear bearing.
  • Basic housing is a chemical tank integrated into the shell-like basic housing with a hollow body is involved.
  • bearing blocks arranged on the push bracket are between which a hose reel is received, and that there is also a storage tray on the push bar, which is arranged in the lower area of the push bar and which further improves the torsional stiffness of the push handle.
  • reference number 1 shows a push handle shown, which consists of a bowl-like, multi-part Plastic part is made.
  • the cross bar 2 is, however, vertical Divided direction so that the push bar is in a front, bowl-like part and into a rear bowl-like part divided, the parting line between the two parts approximately lies in the vertical plane.
  • the two shell-like parts of the Push bars are via appropriate fastening screws interconnected so that the connection is stiff and firm are trained.
  • the two plastic parts of the push bracket 1 are in here the parting plane 41 connected to one another, as shown in FIG. 1 is shown.
  • the rear plastic part 42 is therefore designed much smaller than the front plastic part 43, the two plastic parts 42, 43 each belonging to the complete push handle 1 in the area of parting line 41 unite.
  • FIG Recording 10 provided for receiving a bearing block 9.
  • this bracket is disassembled and it is a cover-like Part available, which with the help of screws 12 closes this receptacle 10.
  • Push bracket 1 each have a bearing block 9 with screws 12, 12a mounted, which is capable of a corresponding transverse axis record a hose reel, not shown.
  • the basic housing 3 of the high-pressure cleaning device is also made of plastic tub-like and has here raised sidewalls 14 in the rear area, which in this Pass the area into a chemical tank 13, which in Sidewalls 14 is integrated and transversely the rear wall of the Basic housing 3 forms according to Figure 2.
  • the upper edge of the basic housing 3 forms an oblique front inclined support surface (support 15), which are arched forward and downward and which in their front area into a backward inclined surface 31 passes, which delimits a cutout 32 in the front area.
  • Directed axes 22 is provided, these stub axles attached to the rear engine cover of the engine assembly 7 are.
  • the axes 22 engage in bearings 23, respectively approximately circular cylindrical with a central recess are formed, the bearings 23 either from a Elastomer material can consist of a hard rubber or from another vibration-damping material, e.g. one Metal element or the like.
  • the bearings 23 in turn are each from above through a half shell 24 covered, with each half shell 24 by front and rear Screws 25 on assigned mounting surfaces on Basic housing are attached.
  • the front support of the motor pump unit 7.8 takes place here by a front foot, which is essentially as Support part 27 is formed for support on the floor.
  • This support part 27 has a recess 28 in which an adjusting screw 30 with a nut 29 is adjustable in height is held.
  • the entire motor pump unit 7,8 can be removed upwards provided the half shells 24 to the as a pivot bearing trained bearings 21 are removed.
  • the hood 4 namely covers the front part of the high-pressure cleaning device and in particular the motor pump unit 7.8 from the front, with the hood using two from each other spaced hood fastenings 37 on the support 15 of the Basic housing 3 is attached.
  • the rear attachment of the Hood 4 takes place in the area of the push bracket 1 via the Attachment 45.
  • a switch box 38 is also provided with the motor pump unit connected, which contains the electrical functional parts.
  • a switch button 39 protrudes from the top of the switch box 38 out of this and reaches through a cutout 40 the hood 4 through.
  • the axis 6 is also according to Figure 1 with a half-shell Construction with the underside of the basic housing 3 connected, the basic housing on its lower edge 46 a circular receptacle 47 open towards the front, in which engages the axis 6 approximately positively and by means of a half shell 48 is secured against falling out, which Half-shell 48 by means of a screw 49 on the basic housing 3 is attached.
  • the advantage of the solution proposed according to the invention is therefore that a relatively large push handle is provided, that of two shell-like plastic parts 42,43, which together form the approximately U-shaped Form push bracket 1, the connecting leg of this U-shaped Push bracket 1 is formed by the cross member 2.
  • the connection level between the push bar 1 and the Basic housing 3 in the area of an inclined forward Support 15 is arranged, which support as close as possible is arranged above the floor, there is the advantage that on the one hand, a cheap one when the push handle is installed Power transmission to the basic housing 3 when pushing the Device is guaranteed and on the other hand when removed Push bar the device has a low overall height.
  • Push bar a relatively straight and vertical (standing) position has, so its central axis is relatively perpendicular is aligned and essentially on the axis of the Chassis is aligned so that an optimal weight distribution given is.
  • the device itself (with lying aggregates) the character of a standing device awarded because the push handle is designed upright and is not inclined at an angle to the rear. this leads to to the fact that it lies above the driving axis.
