Abstract
To treat a surface by a device attracted to the surface by vacuum, it is necessary in most cases to guide a working device with a certain contact pressure over the surface. To be able to set the contact pressure of the working device with little effort, the device according to the invention rests at three points on the surface, one support point being formed by the working device. The force of attraction of the device against the surface is, therefore, accurately distributed to the working device and the other two supports so that the pressure force of the working device can be specifically varied and also controlled by varying the vacuum between the device and the surface.
Claims21
A device for carrying out work on a surface, comprising:
- a housing having edges for forming a substantially closed space with the surface;
- a vacuum disposed at said housing and producing a vacuum in said substantially closed space, the produced vacuum attracting the device to the surface;
- a working device for treating the surface, said working device connected to said housing;
- at least one support connected to said housing for supporting said housing against the surface;
- and
- said working device and said at least one support supporting said housing against the surface in a three-point support.
A device for carrying out work on a surface, comprising:
- a housing having edges for forming a substantially closed space with the surface;
- means for producing a vacuum in said substantially closed space, the produced vacuum attracting the device to the surface, said vacuum producing means disposed at said housing;
- a working device for treating the surface, said working device connected to said housing;
- at least one support connected to said housing for supporting said housing against the surface;
- and
- said working device and said at least one support supporting said housing against the surface in a three-point support.
A method for operating a device for carrying out work on a surface, which comprises;
- providing a housing having:
- edges for forming a substantially closed space with the surface;
- a vacuum;
- a working device for treating the surface, the working device having a support point;
- and
- at least one support having a support point for supporting the housing against the surface, the working device and the at least one support supporting the housing against the surface in a three-point support;
- and
- activating the vacuum to produce a vacuum in the substantially closed space, the produced vacuum attracting the device to the surface and producing a pressure force against the surface, which pressure force, taking into account a point of application of the pressure force on the housing and a configuration of the support point of the at least one support and of the support point of the working device, leads to a predetermined pressure force of the working device against the surface.
A method for operating a device for carrying out work on a surface, which comprises:
- providing a housing having:
- edges for forming a substantially closed space with the surface;
- a vacuum;
- a working device for treating the surface, the working device having a support point;
- and
- at least one support having a support point for supporting the housing against the surface, the working device and the at least one support supporting the housing against the surface in a three-point support;
- and
- activating the vacuum to produce a vacuum in the substantially closed space, the produced vacuum attracting the device to the surface and producing pressure force against the surface and a corresponding predetermined pressure force of the working device against the surface dependent upon a point of application of the pressure force on the housing and a configuration of the support point of the at least one support and of the support point of the working device.
A device for carrying out
- work on a surface, comprising:
- a housing;
- a vacuum disposed at said housing and producing a vacuum between said housing and the surface;
- a working device for treating the surface, said working device connected to said housing;
- a support connected to said housing for supporting said housing against the surface;
- and
- said working device and said support supporting said housing against the surface in a two point support only including two support points, a first of said support points having a given footprint and a second of said support points being elongated and having a footprint larger than said given footprint.
A method for operating a device for carrying out work on a surface, which comprises;
- providing a housing having:
- a vacuum;
- a working device for treating the surface, the working device having a first support point;
- and
- a support having a second support point for supporting the housing against the surface, the working device and the support supporting the housing against the surface in a two point support only including said first and second support points, one of said first and second said support points having a given footprint and another of said first and second support points being elongated and having a footprint larger than said given footprint;
- and
- activating the vacuum to produce pressure force against the surface and a corresponding predetermined pressure force of the working device against the surface dependent upon a point of application of the pressure force on the housing and a configuration of the first and second support points.
