Definitions
- the present invention relates to a reversible braking device comprising a reversible motion transformation device for transforming a translation / rotation movement into a rotation / translation movement successively in a first direction and then in a second direction.
- the reversible clamps are tools commonly used to plumb some equipment after verification and / or adjustment and thus testify the integrity of the equipment and its setting.
- the equipment to be sealed is for example a motor protected by a housing formed by two shells.
- To seal this engine there is provided in the shells one or more eyelets provided opposite each other and adapted to receive the passage of one or more metal son.
- the free ends of the metal wires are twisted by means of a pliers to brake. This twist is then sealed by means of a seal.
- any opening operation of the housing can be detected visually by the degradation of the twist and / or the seal.
- Braking clamps are also used more widely to close down electrical meters and / or sensitive equipment.
- the clamps may also be used to lock in rotation of the screw elements, for example screws and / or nuts, and prevent the unwanted loosening of these clamping elements.
- the locking of the screwed elements is particularly useful when the screwed elements are subjected to repeated vibrations, this which is particularly the case in the aeronautical field, or more broadly in the field of transport. In these areas for which safety is a priority, the good behavior of screwed elements is essential to avoid human and material disasters.
- the clamps can also be used in the building industry to hold in position reinforcements, for example metal rods, before pouring in concrete.
- the clamps can finally be used in the field of orthopedics for example to bind bones together by means of suitable links.
- the clamps to be braked are commonly provided with a clamping device for gripping metal son to twist, for example by means of jaws connected to handles.
- the braking clamps also comprise a device for transforming movements capable of transforming the translation of a pin into rotation of the jaws and thus to obtain the twisting of the metal wires.
- the son are blocked between the jaws by means of the handles.
- the pliers are then held by the end of the spindle which is pulled backwards, relative to the jaws, between its starting position and a rear position.
- the translation towards the rear of the spindle causes the jaws to rotate and thus twist the wires.
- the braking clamps are commonly equipped with a return spring to bring the pin back from its rear position to its starting position, and proceed or not to one or more additional twists.
- reversible locking pliers comprising a reversible motion transformation device for twisting the wires. successively in a first direction and then in a second.
- the reversible reversible movement transformation device of this reversible clamp comprises in particular a spindle provided with two propellers of the same pitch, provided in opposite directions with respect to each other, namely a helix on the left and a propeller on the right. .
- the helix to the right of this pin is coupled to a nut on the right and the propeller on the left is coupled to a nut on the left.
- These nuts on the right and left are housed in a barrel and each comprise a shoulder provided on its periphery with longitudinal engagement grooves.
- the barrel has a lateral opening provided with notches, adapted to receive the lateral wings of a first and a second blocking plates respectively provided opposite the engagement grooves of one of the nuts on the right or on the left.
- Each blocking plate is able to pivot in its notch between:
- a driving position in which it is inclined relative to the longitudinal axis of the barrel, one of its longitudinal ends being housed in one of the engagement grooves of the nut to the right or left corresponding to block the rotation of the nut on the right or left side of the barrel.
- the barrel comprises an actuator, movable in longitudinal translation in the lateral opening, coupled to an inverted U-shaped spring blade, successively soliciting the inclination of the first and second plates between a first configuration in which the first wafer is in its free position and the second wafer is in its drive position, and a second configuration in which the first wafer is in its drive position and the second wafer is in its free position.
- This brake clamp also comprises automatic locking means for locking the handles in their closed position.
- This reversible brake is not practical to use. Indeed, the reversal of the direction of rotation is obtained by a translation, this gesture being impractical to achieve and often requiring the use of both hands.
- the automatic locking of the handles is not always desirable and may interfere with the use of this reversible brake clamp.
- reversible motion transformation device comprises visual cues provided under the actuator and thus to visualize the longitudinal position of the actuator and thus the direction of rotation in which the reversible brake clamp is ready to shoot.
- This reversible braking clip further comprises an elastic member urging the handles to their open position, and a locking device blocking the handles in the closed position.
- This locking device comprises a hook secured to a first handle and circulating in a housing provided in a housing coupled to the second handle, between a locking position in which it holds the hook locked in the housing, and an unlocked position. in which it authorizes the exit of the hook of the housing.
- the latch is requested, from its locked position to its unlocked position, by a spring.
- the user forces the movement of the latch towards the hook by compressing the spring.
- the opening force of the handles applied by the resilient element urging them in the opposite direction is such that it prevents the release of the hook, itself urged by the spring.
- the handles are then in the closed and locked position.
- To unlock the handles the user tightens them slightly towards each other which causes the release of the spring, the movement of the latch and the release of the hook. The locking and unlocking of the handles of this reversible braking device are therefore controlled by the user.
- the reversible braking device described in US Pat. No. 5,560,402 comprises a reversible movement transformation device whose direction of rotation is controlled by an angular displacement of a barrel.
- the present invention aims to remedy these drawbacks by proposing a reversible braking device comprising a reversible motion transformation device, having improved robustness enabling it to withstand difficult conditions of use in a dusty environment and intensive use while remaining reliable over time.
