Definitions
- the present invention is applicable to a hinge mechanism for a circuit breaker type electrical switch tripping lock.
- Such devices typically comprise at least one movable contact capable of moving between two positions respectively in contact and at a fixed contact distance, respectively corresponding to the closure and the opening of the line.
- the mechanical lock is actuated by a control lever of the movable contact between its two positions and comprises in particular a toggle joint with two parallel-parallel branches connecting said handle to (x) contact (s) movable (s), return means of the toggle in the open position and a pivoting trigger relative to the toggle joint by means of the articulation mechanism.
- the function of this trigger is to trigger the lock so that the electrical device is in the open position of the contacts.
- the articulation mechanism of such mechanical locks can not take the conventional shape of a free shaft rotated in bearings, because the return means are in spring consisting of a spring which extends between the branches of the toggle joint, and which does not allow when not the passage dDin single transverse shaft connecting said branches.
- itarticulation is therefore managed on each side by a trunnion or equivalent exceeding dDin of the knee and pivoting elements in a trigger bearing, typically a circular orifice.
- An inverted U-shaped lever attached to the joystick controls the knee / trigger assembly. Its side walls are applied to the outside and cover on both sides the knee / trigger joints, and more particularly the portions of the journals which protrude from the external lateral faces of the release.
- This solution may cause untimely friction of the free end of the trunnions on the inner faces of the side walls of the U-shaped lever, making the operation less "fluid” and may cause wear of the components.
- the remedy could be to virtually do not exceed the trunnions of the trigger holes.
- the side walls of the latter tend to bcarter IQne Itinate at the time of release, especially in the region of the joints, and it could then at worst occur a disengagement of the knee and trigger. It is therefore necessary to find a compromise in the choice of the height of the trunnions, to reduce as much as possible the friction but not to allow said disengagement.
- the present invention provides a solution that does not rely on the structure described above, but is based on a frictionless operating configuration and preventing any uncoupling.
- the release comprises two facing orifices made in lateral walls perpendicular to the pivoting axis and forming bearings allowing a pivot connection for two parallel arms dDin first element of the toggle joint, said orifices being located at the offset level. lateral to the inside, respectively, towards the inside of each side wall, forming a slot which is perpendicular to the walls for the passage of said arms.
- This slot extends firstly into a first portion of the orifice made in the non-shifted part of the walls and allowing the insertion of the ends of said arms, and secondly into a second orifice portion in the offset part, provided at least partially in the bottom to form a housing sSuvrant to 1'Interieur respectively outward walls, the periphery of said housing being rounded and adapted to guide the rotation of I'applis d'allure rounded arms of the toggle.
- the solution of the invention has also been designed so as to obtain all forms by cutting-bending-stamping / striking, to facilitate the manufacture of the components of the mechanism according to traditional mechanical techniques automatable.
- the offset that exists between the plane of the ends of the arms of the element of the toggle joint and the walls of the trigger at each orifice allows, in combination with the particular form of this orifice, a mounting of the one in the other and, in the mounted position, a locking of one in the other which does not prevent the pivoting movement necessary for the operation of the assembly.
- the plane of the end of rounded pace is located, in the extension of each arm, laterally offset to the opposite arm.
- each orifice are partially separated by a cam guiding the extremity of the arms of the toggle joint from the first to the second portion of each orifice, said cam being located so as to block each of said ends in its housing when it is there. inserted.
- the cam comprises, in the vicinity of the first portion of the housing, a first part with a rounded ramp, followed by a top forming a locking stop for the ends of the arms in their housing.
- the bottom of the second portion of each orifice and the offset of the extremities of the toggle arms are obtained by striking / stamping.
- the manufacturing is therefore performed by simple operations, automatable and easily controllable in the context of an industrial manufacturing process.
- One of the technical advantages of the hinge mechanism of the invention lies in the particular configuration avoiding friction between the arms of the toggle joint and the inverted lever which is attached to the control lever of the electrical equipment equipped with such a system.
- a second important advantage results from the lateral support of the arms of the toggle which is ensured by the particular configuration used.
- FIG. 2 shows, still in perspective view, a part of a cutting apparatus comprising the hinge mechanism of the invention
- FIG. 3 is a front view of the representation of FIG. 2;
- FIG. 4 represents a view in section of an enlarged detail of
- FIG. 5 shows, in a median plane of symmetry, the hinge mechanism according to the invention.
- the toggle joint consists of a pair of upper arms (1, 2) articulated by means of a shaft (3) to a pair of lower links (4, 5).
- the pairs of arms (1, 2) / links (4, 5) constitute the parallel branches of the knee joint.
- the latter retransmits the movement of a control member (not shown) to movable contacts in the direction of opening and closing.
- a trigger lock of a switchgear according to the invention mounted with a pivoting connection to a part called trigger (6) which is able to unlock in particular to the by means of return means the stable position resulting from the closure of the contacts, according to a conventional design well known per se.
- the trigger (6) appears in FIG. 2.
- the second portion (16) of said orifice (9), located in the offset portion (placed above the offset (11) of the wall (7)) has a rounded shape that can accommodate said end (13) of the arm (1) and it is provided with a bottom outward supplementing said housing.
- this housing formed in the second portion (16) of the orifice (9) opens towards the inside of the wall (7), and houses the end (13) offset outwards. (see Figure 1) of the arm (1), thus preventing any lateral movement to the outside of the latter.
- a cam (17) guides the end (13) of the arm (1) of the first portion (15) of the orifice (9) through which it is inserted to the second portion (16), in which it is housed permanently after insertion.
- This cam (17) also retains the end (13) in the second portion (16) of ISmfice (9), preventing the reverse path of the insertion path of the toggle in the trigger (6).
- the cam (17) is in the first portion (15) of the orifice (9), that is to say the one in the side wall of the trigger (6) which is not shifted towards the 'outside. Thanks to the particular shape of the orifice (9), and the inverted double offset of the rounded ends (13, 14) of the arms (1, 2) on the one hand (see FIG. 1) and upper parts of the side walls ( 7, 8) of the release (6) on the other hand, the joint plays its role fully by leaving a degree of freedom of pivoting to both parts and resisting any shocks. With reference to FIG. 5, it should be noted that an inverted U-shaped lever (18) integral with the control lever (19) cooperates with rounded protrusions (20) of the release (6) through curved surfaces (21). said lever (18) to facilitate the transmission of the movement of the lever (19) to the toggle lever via the trigger (6) against the powerful means of return used in this type of product.
