DESCRIPTION:
BRIEF SUMMARY
The invention relates to a high-pressure cleaning device comprising a high-pressure pump, a liquid supply and a pressure line for the liquid supplied by the pump as well as a housing surrounding the pump.
Such high-pressure cleaning devices are increasingly manufactured as small, portable devices which are also used by private persons. It is known to provide devices of this type with a carrier handle such that they can be carried to the respective place of use.
However, the weight of such devices is relatively great, so that their frequent transportation is strenuous. The object of the invention is to design a high-pressure cleaning device of the generic type such that it can be easily transported to the respective place of use and that a space-saving construction can still be maintained which, in addition, facilitates the conventional transport of the device by carrying.
This object is accomplished in accordance with the invention, in a high-pressure cleaning device of the type described at the outset, in that rollers are arranged on the underside of the housing in the area of a side edge and that a handle insertable into the housing is mounted therein, the handle being shiftable between an inserted position in the housing and an extended position and securable in both of these positions.
In this manner, it is possible to transport the device by rolling it. For this purpose, the handle is pulled out of the housing and, consequently, makes it possible to tilt the housing over the rollers so that the housing can be conveyed on the rollers with the aid of the extended handle. The handle is pushed into the housing again at the place of use or when being stored so that the small overall dimensions of the housing are not enlarged. In addition, it is possible to simultaneously use the inserted handle, which is secured in the housing, as a carrier handle. The device can then be transported in the usual way by carrying.
It is advantageous for the handle to be designed as a U-shaped bar of which both arms are insertable into the housing.
A preferred embodiment is characterized in that the U-shaped bar (15) consists of two L-shaped parts of equal construction which are connected with each-other in the area of the handle.
In this respect, is favorable when the connection of the two L-shaped parts results by means of detent projections and locking receiving means, which are arranged next to each other on each L-shaped part and, when fitted together, interact with the locking recess or detent projection of the other L-part, respectively.
A particularly favorable design results when the handle in the inserted position abuts on a fixed carrier handle on the upper side of the housing or is pushed into the carrier handle. Thus, the housing has its own stable carrier handle while the insertable handle is only used in the extended position in which this handle enables the device to be easily rolled. In contrast thereto, the handle in the inserted position abuts on the carrier handle or is accommodated therein, so that an integrated carrier handle results which completely corresponds in size with the fixed carrier handle.
It is also advantageous when the rollers are part of a shaft, which has a reduced diameter between the rollers. In this way, the shaft can be manufactured as one part, for example, as a blow molded part. Besides this, the reduced diameter between the rollers makes it possible to arrange air inlet or outlet openings in this area so that in spite of the arrangement of the shaft, cooling air can be supplied or discharged in a space-saving way.
For use, the device is set up such that the rollers serve as support feet. In addition, at least one support foot can be arranged on the underside of the housing on the side edge averted from the rollers, the support foot defining together with the rollers a standing plane arranged parallel to the underside of the housing.
In this respect, it is advantageous for the support foot to project sideways beyond the housing and to form a further standing plane together with supp
