FR3051533A1 - INTEGRATION IN OR ON THE STEERING WHEEL OF A GAS BOTTLE FILLING PLUG, A REVERSIBLE RATCH MECHANISM - Google Patents

Abstract

Integration of a reversible ratchet mechanism in a pressurized gas bottle filling socket, in order to limit the effort of the operator to a movement back and forth without releasing the steering wheel of the socket during screwing or unscrewing of this catch. The aim is to reduce the recurring pathologies of operators at the wrist and elbow.

Description

DESCRIPTION OF THE INVENTION 1- Technical Field of Invention; The invention relates to the field of filling pressurized gas cylinders. - industrial and medical gases conditioned at 200-300 bar - and more particularly the filling plug.

The filling plug is the equipment that is connected to the valve of the bottle, to allow filling of the latter; the filling plug is also connected via a hose to the rest of the gas distribution system. 2- Problem to which the invention responds: The operator in a packaging center must connect the filling plugs on the bottles to fill and then disconnect them at the end of the cycle. This operation is repeated several dozen times a day for all the catches of the production unit. Usually, the operator manually screws (or unscrews) the tap on the tap, via a steering wheel. Repetition of these operations induces inflammation in the wrist and elbow of the operator. 3- Presentation of the invention;

A filling plug is usually composed of a front part which connects to the tap mounted on the pressurized gas bottle, a flywheel secured to this front part, to perform the operations of screwing / unscrewing on the tap of the bottle, a rear part that connects to the filling installation and allows the passage of gas to the front. The invention consists in integrating into or on the steering wheel of the filling socket, a reversible ratchet mechanism. The reversible ratchet mechanism is a mechanism allowing the choice of a direction of rotation of the driven part (the choice is given by a selector), while the driving part can be actuated in both directions: in the direction of rotation of the part driven, it has the effect of causing it, in the opposite direction, it has no effect on the driven part.

For a traditional filling socket, the steering wheel is secured to the body (front portion) of the socket; the plug object of the invention has a steering wheel which is movable relative to the body, except during the working phase: the ratchet mechanism causes the rotation of the grip body.

The ratchet mechanism is partially integral with the body of the filling plug, while the other part is secured to the steering wheel. The reversible appearance of the pawl is given by the selector which allows to reverse the direction of rotation of the movable part of the socket (screwing or unscrewing the socket on the valve of the bottle).

In this way, the operator grasps the steering wheel one time and prints it back and forth until the tightening, which is much more ergonomic than the repeated sequence: taking the steering wheel -rotation maximum - let go. 4- Presentation of the plans:

The Folio 1/3 has a filling socket composed of: A movable part (front part) of the filling plug, which allows to come to mate by screwing on the riobinet of the gas cylinder. A fixed part of the socket (rear part) which is connected to the filling installation. A steering wheel incorporating the ratchet system.

Folio 2/3 presents by transparency the integration of the ratchet mechanism:

The ratchet bracket on which is fixed the steering wheel and which integrates the mechanism (selector, springs and locking tabs).

The toothed wheel which is integral with the movable part of the socket.

Folio 3/3 is a sectional view of% which shows the coupling of the toothed wheel on the moving part of the socket. 5- app.liçiaMQn; The invention can be applied industrially in two ways: making new outlets (new installations or replacing existing ones) and integrating the mechanism into existing outlets.

This application has an international vocation.

Claims (1)

The claim has as its scope the filling sockets, also called charging assemblies, in the field of pressurized gases: the filling plug is the equipment that connects to the tap of the pressurized gas cylinder, to allow the filling of said bottle. The claim relates to the integration of a reversible ratchet mechanism in or on the steering wheel of the filling plug, the reversible ratchet mechanism being characterized in the following manner: mechanism allowing the choice of a direction of rotation of the driven part ( the choice is given by a selector), while the driving part can be actuated in both directions: in the direction of rotation of the driven part, it has the effect of driving it, in the opposite direction, it has not no effect on the training part. Device according to this claim characterized by the toothed wheel which is secured to the movable part of the socket. Device according to this claim characterized by the flywheel attaches to the ratchet support, which ratchet support integrates the locking lugs of the toothed wheel and their springs, the direction of rotation selector. Device according to this claim characterized by the toothed wheel which is secured to the movable part of the socket.
