Description

The invention relates to a high-pressure cleaning device Hose reel according to the preamble of protection claim 1. Such high pressure cleaning devices with hose reel are in various embodiments have become known. characteristic for these embodiments is that the hose drum approximately centered over the device and also approximately centered over the hood in the longitudinal center plane of the device is arranged. It is here however, the hose reel in the rear is not known Area of the device, e.g. near the push handle, too embarrassed.

In the known high-pressure cleaning devices with Hose reels have the disadvantage that an unfavorable Weight distribution must be accepted, because the Hose reel sits outside the center of gravity of the device, is expansive because it is a separate component on the device is arranged. But after such high pressure cleaning devices sold with and without hose reel so far, it has been difficult to find a bracket for Train hose drums so that you can do that without Hose reel delivered device not easily considers that this is a storage for a hose reel heard.

In the case of devices mounted with hose drums, there is moreover the disadvantage that the holder for the hose reels is relatively difficult to install and involves high costs.

The publications DE 39 40 543 A1 and GB 2 084 685 A and EP 0 770 575 A are known. DE 39 40 543 A1 describes a pressure washer that works within a Hose reel is arranged. The hose reel is open a mobile frame that stored from a tubular rod is assembled and a conventional form of a Has hose cart. The high pressure cleaner is therefore as a related unit is formed where it is not the high pressure cleaner is optionally available with or without To equip hose reel.

Furthermore, in the dimensions due to the structure for the hose reel and the motor and arranged therein Pump elements only poor performance for high pressure feasible because of correspondingly powerful components the space is missing.

GB 2 084 685 A describes a movable high pressure cleaning device with a rigid cover for Drive units (drive shafts, V-belt pulleys and V-belt) One possibility is a hose aufzuwinden. This cover extends in the bottom Half of the high pressure cleaner behind one Pipe rods which serve as a frame for high-pressure cleaning devices serves. This framework is so high drawn that it doubles as a handle for transportation purposes can be used. It is part of the one-piece frame trained and not removable. By arranging the Cover behind the frame results in a bulky structure the device is unwieldy when moving the device is. The cover on which the hose is wound the person who spends the device in the way.

EP 0 770 575 A describes a high pressure cleaner with a fixed hose reel. This hose reel is located however, in the bottom area of the housing of the pressure washer arranged. Thus the high pressure generating units are in disadvantageously very high above the axis of the transport wheels positioned, which causes a high instability of the device. In addition, the housing of the hose drum in the Housing given a much larger space, so that a compact design is not possible.

The invention is therefore based on the object High pressure cleaning device with optional to be attached Refine hose reel so that the attachment is particularly simple, space-saving and inconspicuous.

To achieve the object, the invention is thereby characterized in that the hose drum on the push bar of the Device is rotatably mounted and that the push bar in is substantially U-shaped, so that the Hose reel at least partially in the space engages between the U-legs.

With the given technical teaching, the essential results Advantage that according to the invention the hose reel is not more above the hood and for example on the hood itself is attached, but that the hose drum rotatable on the Push handle is stored. This has the advantage that at an essentially vertically upright push bar, the with its longitudinal axis also advantageous with the rest Travel axis of the high-pressure cleaning device is aligned, one Hose reel is attached, which is approximately above the Center of gravity of the device is arranged. This will make the Driveability of the device is significantly improved and also the Tipping safety and portability.

In a preferred embodiment of the present invention it is provided that the hose drum in bearing blocks on Push bracket is attached, preferably a first bearing block already attached to one U-leg of the push handle is and this bearing block at the same time as a receptacle for the High pressure lance is used. It is accordingly provided that the High pressure cleaning device without hose reel with this only bearing block is delivered, for which case the Bearing block as support for the high pressure lance and possibly as Holder for the electrical line or the high pressure line is trained. So you can see the one so delivered High pressure cleaning device does not indicate that there is an attachment is provided for a hose drum.

In this bearing block, the receptacle for one is preferred Axis (stub axle) of the hose drum provided, this Recording preferably by corresponding detachably inserted Cover is covered.

Now such a high-pressure cleaning device is to be used together with a hose reel can then be delivered Hose reel already in a particularly simple way already installed in the factory or by the customer. It is namely only that the hose reel is delivered together with the other bearing block, whereby it it is preferred that already on this bracket side High-pressure screwing of the high-pressure hose to the Connecting hose is integrated on the high-pressure cleaning device, so that when assembling this invention Hose reel it is sufficient to attach the other bracket a place (relatively hidden and hidden) fasten the opposite side of the push bar and otherwise the opposite stub axle Hose reel in the already existing bearing block insert, then the corresponding cover is removed become.

This results in a particularly simple and but at the same time also a professional bracket Hose reel on the push bar one Pressure washer, in the way it was before was not known.

The advantage here is that the simple assembly another bearing block the hose reel in particular already pre-assembled on the High-pressure cleaning device attached in the area of the push handle becomes what was previously unknown.

If the high-pressure cleaning device is to be transported, it is preferred if the push bar as a whole is light releasably on the base housing of the high-pressure cleaning device is arranged. For this purpose it is provided that on each side of the push bar there are two screws each, which are easily accessible from the outside and which have the push handle one side each on the basic housing of the Fasten the high-pressure cleaning device. By simply loosening it of these four existing screws can be the Push bar together with the hose reel attached to it can be easily removed and separated from the High pressure cleaning device to be transported. Of course, it is provided here that Connection hose between the hose reel and the High pressure cleaning device also easily detachable on the Attach high pressure cleaning device.

The high pressure cleaning device shown in Figure 1 consists in essentially from a push bracket 1, which consists of two separate half shells. It is a front one Blown plastic part 5 available, which over a parting plane 4th with a rear plastic blow part 6 via screws is connected, the two plastic blow parts 5,6 result in a total of approximately a U-shaped part (see FIG. 4), and the connecting leg of this U is designed as a cross member 3 is.

The cross member 3 is also separated by the parting plane 4, the parting plane 4 in the vertical direction through the two Blown plastic parts 5.6 runs through, so that the cross member 3rd also consists of two interconnected parts, whereby the cross bar 3 but each with the front plastic blow part 5 and also with the rear plastic blow part 6 is connected in one piece.

It is important that on one side of the push bar 1 Bearing bracket 2 is fastened, with screws 15.16 in corresponding receptacles 17 are arranged and this Hold bracket 2.

The push bar 1 is easily detachable as a whole a total of four screws with the basic housing 9 of the high-pressure cleaning device connected. The basic housing 9 is in essentially trough-shaped and on each side of this trough-shaped housings are arranged in pairs Screws 7,8 for fastening one spar each Push bracket 1 arranged.

The paired screws 7,8 are each from easily accessible from the outside, so that the push bar 1 overall is designed to be easily removable. The high-pressure cleaning device is covered from the front by a hood 14 which is light is releasably attached to the base housing 9. Inside is the motor pump unit is arranged, and it is a front, foot-side stand 13 available and a uniaxial Running gear consisting of the axle 11 and the wheels 12 consists.

It is added that the connection level between the Push bracket 1 and the basic housing 9 in the area of a support 10 takes place, which is inclined obliquely forward on the basic housing 9 is arranged. This has the advantage that the Push bracket 1 is arranged approximately vertically above the axis 11 and is around the center of gravity of the device. That way the device can be moved easily and there are no tilting Tilting moments when driving the device.

It is now important that in the space 49 between the U-shaped trained push bar spars of push bar 1 a Hose reel 18 for receiving a high pressure hose is provided which is rotatable in two from each other there spaced bearing blocks is held 2.45. The one bearing block 2 is simultaneously connected to a shelf 19 for one High pressure lance and is over the screws previously described 15, 16 in a receptacle 17 on the front of the front Blown plastic part 5 of the push bracket 1 held.

The hose reel is shown in the Figures 4 and 5 essentially of two side walls 23, the are arranged on the end of a drum 24 and Non-rotatably and possibly also integrally connected to it are. This creates a receiving space for winding up a HD hose 25 formed.

An axis 21 is flanged to the side cheek 23, the associated axle holder 46 on the Bearing block 2 passes through and at its outer, free end is vertically interspersed with a twist grip 20 on the latter free outer end a handle 22 is arranged.

It is important here that the twist grip 20 in the area of his Recording in axis 21 rotatable by 180 ° and spring-loaded is held so that the handle 22 both in their outward facing position as well as in their inward facing Position (handle 22 ') can be pivoted.

In the inward position (handle 22 ') this serves Handle then as a stop on the associated front edge of the Push bracket 1, as is the case, for example, in FIG. 3 is shown.

Otherwise, it can be provided that the hood 14 one trough-shaped incision 26 in the area of the hose drum 18 have to undisturbed pivoting of the rotary handle (Handle 22 ').

By this inward pivoting of the handle 22 in its position 22 'can thus the hose reel in a certain unwind or Winding position can be locked and against further winding Unwinding are secured.

In Figure 2, the prepared bracket on the opposite side of push bar 1 for another Bearing block 45 shown. In unprepared condition, this will be Bracket covered by a cover 48 which means Screws in assigned receptacles 47 on the push handle (more precisely is held on the plastic blow part 5).

If the hose drum 18 is now to be fastened, then is for the opposite axis end of the axis 21 of the hose drum 18 of the bearing block 45 is provided, which together with a High pressure screw connection firmly on the hose reel is made up.

The connecting hose 27 for the inlet of the high pressure medium 6 in this case runs through a hose reel HD connection 36 in a screw-in nipple 37, which in a associated bearing bush 38 is screwed.

So this is a quick screw connection that is particularly easy and reliable to install.

The bearing block 45 again consists of a Plastic part, which has a central receptacle for the Passage of the bearing bush 38 forms. The bearing bush 38 will 'sealingly closed on the end face by a sealing part 32, which carries a sail ring and an O-ring and one Support ring.

A bearing part 40 is rotatable and sealing over a associated O-ring seal held in the bearing bush 38, this bearing part 40 carries a longitudinal bore 33 which of a transverse bore 34 is penetrated, which in turn on the outer circumference opens into a circumferential annular groove 35. In these According to FIG. 6, the annular groove 35 opens into the screw-in nipple 37 Quick fitting 28 so that the high pressure medium over this Annular groove 35 and the transverse bore 34 in the longitudinal bore 33 entry.

The bearing part 40 is by means of a nut 41 on one Side cheek 23 of the hose drum 18 fastened and settled inwards into the area of the drum 24 with a stub-shaped Inner part 43 continued.

The longitudinal bore 33 opens into this inner part 43, where at the same time an HD hose screw connection 30 for the hose section 31 is attached.

This piece of hose 31 is held in a nut 42 and the Nut 42 is rotatably connected to a screw part 44, which is sealing and firm via an assigned threaded screw connection is connected to the inner part 43.

The tube piece 31 is part of the on the drum body Drum 24 wound high pressure hose 25.
