DESCRIPTION:
BRIEF SUMMARY
The present invention concerns a multi-purpose revolving connecting assembly capable of connecting different types of dental instruments to a power supply.
More particularly, this invention concerns a revolving connecting assembly capable of being connected to dental instruments whose rear portions, which are intended to assure the connection thereof to the connecting assembly, have different geometrical configurations to each other.
Conventional dental equipment which is used by dental practitioners for dental treatments, is generally formed of a power supply which is designated, in the profession, by the term <<unit>> and which is capable of providing the agents and power necessary for implementing said treatments.
This equipment generally includes several supply hoses, one end of which is connected to the unit, while the other end is intended to be coupled, via a specific coupling socket, to the rear of one or more dental instruments which are available on a display cabinet.
In order to be mechanically fixed onto an instrument, each coupling socket is generally fitted with a rotating nut which is arranged to be screwed onto the rear of such instrument, the latter including a threading provided for such purpose.
This assembly, formed of the hose, socket and rotating nut, is designated, in dental circles, by the term <<connecting assembly>>.
Thanks to this socket and the nut, according to the operations which the has to perform, the dental practitioner can fit the necessary instruments to the respective connecting assemblies of his equipment as a function of their compatibility.
For reasons of simplification, rationalization and economy, it is sought to improve this compatibility and to allow the connection of the largest number of instruments or even all the instruments to a same connecting assembly, and to fit the equipment with several connecting assemblies of the same type, or even a single connecting assembly capable of assuring the connection of all the instruments to the unit.
The instruments which exist on the market and with which dental practitioners are already provided, have rear portions of different geometrical configurations, i.e. of different shape/and or dimensions, which stands in the way of such compatibility.
Thus, an object of the present invention is to provide a revolving connecting assembly solving this problem which can, via a simple, inexpensive solution, allow connection to different types of dental instruments having rear portions of different geometries.
The invention therefore concerns a multi-purpose revolving connecting assembly including:
a hose including coupling means, such as at least one electric power cable and/or at least one fluid conveying conduit, these coupling means being intended to be connected to the power supply,
a connector provided for assuring the coupling, at the front of the connecting assembly, between a dental instrument and the coupling means, this connector being formed of a first fixed coupling piece attached to the coupling means and a second mobile and removable connection, which can be connected to the first coupling piece and which is provided to be connected to the dental instrument, the second coupling piece being able to be rotatably mounted and held axially on the first coupling piece via a rotating stopping ring, blocked axially on the first coupling piece and able to be screwed onto the second coupling piece, and
a nut able to be fixed to the rear portion of the instrument and, including a support face intended to abut against a corresponding shoulder of the connecting assembly in order to push and install the connector onto the rear portion of the dental instrument, when the nut is screwed in, this connecting assembly being characterized in that the nut is formed, at the front, of a removable sleeve and, at the rear, of a bush which can be connected to the sleeve by a screw-nut system, the sleeve being provided to be fixed to the dental instrument, while the bush has a support surface intended to abut against the
