DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a connection device between a suction pipe, of the flexible type, and a mobile vacuum cleaner unit.
The present invention concerns a device for closing and ejecting a disposable bag of a vacuum cleaner, the bag being fixed, during a cleaning operation on a part of the housing of said vacuum cleaner.
The invention is applied in a general manner to any mobile vacuuming unit of the vacuum cleaner type, which is displaceable by the user in a zone to be cleaned and comprises a bag for trapping dust, being removable and disposable.
PRIOR ART
The state of the prior art in this field is constituted, for example, by U.S. Pat. No. 3,335,744, which describes a fixed, central vacuum cleaning system, connected to a suction pipe. The vacuuming system comprises a blocking valve arranged on a suction opening and elastically retractable during introduction of the suction pipe. The system thus described concerns a central installation associated with an assembly of suction conduits distributed in the floors and/or the walls of the building.
It is equally known to provide blocking means for bags, for example by the intermediary of French Document A-932,776, which describes a bag furnished with a closing means. This latter pivots between an opening position and a closing position of the filling opening of the bag, with the aid of a mechanical system constituted by a pivot axis, an elastic restoring means as well as a part serving as an abutment for the closing means, arranged on a rigid plate of the bag. Such a system presents a group of inconveniences and notably, in its construction, for which a number of distinct and substantial pieces are necessary, thus generating a high fabrication cost.
In addition, the arrangement of the system and more particularly of the closing means on the rigid plate, in an accessible manner, weakens said system, and the particular configuration of the closing means does not permit simple and/or automatic operation thereof with an independent control member.
The object of the present invention is to remedy the inconveniences of the prior art and to achieve in a simple manner, which is inexpensive and easy to utilize, a vacuum cleaner whose suction pipe connection system functions in an optimal manner in association with a closing means of the bag for trapping dust.
The object of the present invention consists in furnishing a closing device for the vacuum cleaner bag which the user can manipulate without entering into direct contact with said bag during the closing operation.
Another object of the present invention is to furnish the user of vacuum cleaners with a simple and nonrestricting device for ejecting said bag from the housing of the vacuum cleaner.
Another object of the invention consists in utilizing a means for closing the vacuum cleaner bag which occupies a limited space, is easily fabricated, is inexpensive and can be disposed in an opening or closing position at the will of the user.
Another object of the invention is to furnish a safety device intended to prevent fixation of the suction pipe on the housing of the vacuum cleaner when the bag is closed.
A supplementary object of the invention is to furnish an automatic closing device for vacuum cleaner bags.
SUMMARY OF THE INVENTION
The objects of the present invention are achieved with the aid of a device for connection between a suction pipe and a vacuum cleaning unit, constituted by an attachment nozzle forming the extremity of the suction pipe mounted in communication with the vacuum cleaning unit, which comprises a closing flap displaceable between an opening position and a closing position of the suction inlet of said unit, with the aid of a control member as well as means for locking the nozzle on the vacuum cleaning unit, characterized in that the vacuum cleaning unit is a mobile vacuum cleaner comprising a housing in which is disposed a removable bag, serving as a dust recovery container, the closing flap being disposed on the bag, and the control member cooperating with
