Title of the invention: LOCKING SYSTEM WITH DOUBLE RATCHET CONFIGURATION

[0001] REFERENCE TO RELATED REQUESTS

[0002] The present application claims the benefit of U.S. Provisional Patent Application Serial No. 63 / 710,432 filed on October 22, 2024.

[0003] BACKGROUND

[0004] Exemplary embodiments of this disclosure relate to the art of vehicle locks.

[0005] Conventional locking systems use a bolt or claw rotating around a fixed pivot and a catch or ratchet rotating around a fixed pivot to retain a moving strike plate. The vast majority of locking systems retain the strike plate in two distinct positions, with some linear separation. In the case of a large force applied to the strike plate with the conventional locking system, it may not be possible to rotate the catch or ratchet out of the engagement of the bolt or claw, thus preventing the lock from releasing the strike plate.

[0006] An alternative design of the locking system consists of a fork bolt or claw rotating about a fixed pivot, a primary stop or ratchet rotating about a fixed pivot, and a secondary stop or ratchet rotating about a fixed pivot. In this alternative design, the primary stop or ratchet is pre-loaded such that it tends to automatically disengage from the fork bolt or claw once the secondary stop or ratchet moves out of engagement with the primary stop or ratchet. The alternative design requires significantly less energy to release a high load applied to the strike plate. However, the alternative design described so far is generally not capable of moving from the second strike plate position to the first strike plate position during the lock closing operation.

[0007] One solution to this problem is a locking system that uses only the primary-secondary ratchet or detent system to hold the bolt or claw in the first strike position. A separate ratchet or detent lever is then used to hold the bolt or claw in the second strike position. This solution is not optimal, as it requires additional components and manufacturing steps.

[0043] A detailed description of one or more embodiments of the disclosed apparatus and method is presented here by way of example and not limitation with reference to the Figures.

[0044] This disclosure relates to a locking system 100 comprising a fork bolt or claw rotating about a fixed pivot, a primary stop or ratchet that is capable of rotating either about a fixed pivot or about the point of contact between the primary and secondary stops or ratchets, and a secondary stop or ratchet that is capable of rotating about a fixed pivot. This disclosure offers the advantages of the alternative locking system described below. above, but is able to move from the second strike position to the first strike position without the addition of several components.

[0045] Figure 1 shows the locking system 100 in a first strike position. Here, a strike plate 1 is held in the first strike position by the fork bolt or claw 2, which is prevented from rotating about its fixed pivot or fork bolt or claw pivot 3 by a stop or primary ratchet 4. The stop or primary ratchet 4 is prevented from rotating about its fixed pivot or stop or primary ratchet pivot 5 and from engaging the fork bolt or claw by a secondary stop or ratchet 6, which rotates about a fixed pivot or a secondary stop or ratchet pivot 7.The primary stop or ratchet 4 is constrained to its fixed pivot 5 with an arc-shaped slot or elongated opening 8, the center of said arc or elongated opening coinciding with the center of the radius 9 of the primary stop-secondary stop engagement zone of the primary stop or ratchet 4. In the first strike position, the strike 1 is in a first strike position which corresponds to the primary or locked position of the bolt or claw 2. In the first strike position, the primary stop or ratchet 4 is in an engaged position, so that it comes into contact with the bolt or claw 2 to prevent its counterclockwise rotation with respect to the view illustrated at least in [Fig. 1].

[0046] Figure 2 shows the locking system in a second strike position. In the second strike position, the strike plate 1 is in a second strike position which corresponds to a secondary or partially locked position of the bolt or claw 2. In the second strike position, the stop or primary ratchet 4 is always in an engaged position, so that it comes into contact with the bolt or claw 2 to prevent its counterclockwise rotation relative to the view illustrated at least in Figure 2.

[0047] Figure 3 shows the locking system during the stroke of the strike plate 1 from the second strike plate position (Fig. 2) to the first strike plate position (Fig. 1), which also results in a corresponding movement of the bolt or claw 2 from the secondary or partially locked position to the first or primary locked position. This can be due to a closing or clamping force applied to the locking system 100. The movement of the strike plate 1, as indicated by arrow A, causes the bolt or claw 2 to rotate around its fixed pivot 3. The bolt or claw comes into contact with the stop or primary ratchet 4, which causes the stop or primary ratchet to rotate around the radius 9 of the primary stop-notch engagement zone The secondary stop of the primary stop notch also causes the fixed pivot 5 to move within an arc-shaped slot or elongated opening 8. This allows the bolt or claw 2 to move from the secondary or partially locked position to the primary or first locked position. In other words, this movement of the primary stop notch or ratchet 4, including the movement of the fixed pivot 5 within the arc-shaped slot or elongated opening 8, does not prevent the bolt or claw 2 from moving from the secondary or partially locked position to the primary or first locked position.

[0048] At a certain point in the striker stroke, the primary stop or ratchet 4 and the secondary stop or ratchet 6 will return to the positions shown in [Fig.1].

[0049] Figure 4 shows the locking system 100 with the secondary ratchet or catch 6 rotated out of engagement with the primary ratchet or catch 4. This can be achieved by an actuator or handle 101 functionally coupled to the secondary ratchet or catch 6. The force from the strike plate 1, as indicated by arrow B, causes the bolt or claw 2 to rotate about its fixed pivot 3 and to contact the primary ratchet or catch. The contact force vector for this interaction, as indicated by arrow C, generates a moment on the primary catch about its fixed pivot 5, as indicated by arrow D. Given sufficient strike plate force in the direction of arrow B, the primary ratchet or catch 4 will rotate out of engagement with the bolt or claw 2.

[0050] Fig. 5 shows the locking system 100 in a released position.

[0051] Referring now to Figures 6 to 10, the locking system 100 according to various embodiments of this disclosure is illustrated. Here, the locking system 100 is shown with a frame or support plate 102 to which the fork bolt or claw 2, the primary stop or ratchet 4, and the secondary stop or ratchet 6 are pivotally or rotatably attached. In Figures 6 to 10, the fork bolt or claw 2, the primary stop or ratchet 4, and the secondary stop or ratchet 6 have a slightly different configuration from those illustrated in Figures 1 to 5. Also shown are a primary stop or ratchet spring 104 and a secondary stop or ratchet spring 106.The primary ratchet or stop spring 104 engages the primary ratchet or stop spring 104 in an engaged position relative to the fork bolt or claw 2 and the secondary ratchet or stop spring 106 engages the secondary ratchet or stop 6 in an engaged position relative to the primary ratchet or stop 4. The fork bolt or claw 2 can. to be solicited in the open position by a spring not shown and the fork bolt or claw 2 is also rotated in the open position by the movement of the strike plate 1 in the direction of arrow B, which can be attributed to the compressed seal around a door to which the locking system is attached, as is known in related arts.

[0052] Figures 6 and 6A show the locking system 100 in a first strike position. [Fig. 6A] is an enlarged view of a portion of [Fig. 6]. Here, a strike plate 1 is held in the first strike position by the bolt or claw 2, which is prevented from rotating about its fixed pivot or bolt or claw pivot 3 by the primary ratchet or catch 4. The primary ratchet or catch 4 is prevented from rotating about its fixed pivot or primary ratchet or catch pivot 5 and from disengaging the bolt or claw 2 by a secondary ratchet or catch 6, which rotates about a fixed pivot or secondary ratchet or catch pivot 7.The primary stop or ratchet 4 is constrained to its fixed pivot 5 with an arc-shaped slot or elongated opening 8, the center of said arc or elongated opening coinciding with the center of the radius 9 of the primary stop-secondary stop engagement zone of the primary stop or ratchet 4. In the first strike position, the strike plate 1 is in a first strike position which corresponds to the primary or locked position of the bolt or claw 2. In the first strike position, the primary stop or ratchet 4 is in an engaged position, so that it comes into contact with the bolt or claw 2 to prevent its counterclockwise rotation with respect to the view illustrated at least in [Fig. 6].

[0053] [Fig. 7] shows the locking system in a second strike position. In the second strike position, the strike plate 1 is in a second strike position which corresponds to a secondary or partially locked position of the bolt or claw 2. In the second strike position, the stop notch or primary ratchet 4 is always in an engaged position, so that it comes into contact with the bolt or claw 2 to prevent its counterclockwise rotation relative to the view illustrated at least in [Fig. 2].

[0054] Figures 8 and 8A show the locking system 100 during the stroke of the strike plate 1 from the second strike plate position ([Fig. 7]) to the first strike plate position ([Fig. 6]), which also results in a corresponding movement of the bolt or claw 2 from the secondary or partially locked position to the first or primary locked position. This can be due to a closing or clamping force applied to the locking system 100. The movement The strike plate 1, as indicated by arrow A, causes the bolt or claw 2 to rotate around its fixed pivot 3. The bolt or claw 2 comes into contact with the primary stop or ratchet 4, which causes the primary stop or ratchet to rotate around the radius 9 of the primary stop-secondary stop engagement zone of the primary stop, which also causes the fixed pivot 5 to move in the arc-shaped slot or elongated opening 8. This allows the bolt or claw 2 to move from the secondary or partially locked position to the primary or first locked position.In other words, this movement of the stop notch or primary ratchet 4, including the movement of the fixed pivot 5 to move in the arc-shaped slot or elongated opening 8, does not prevent the fork bolt or claw 2 from moving from the secondary or partially locked position to the primary or first locked position.

[0055] At a certain point in the striker stroke, the primary stop or ratchet 4 and the secondary stop or ratchet 6 will return to the positions shown in [Fig.6] and 6A.

[0056] Figure 9 shows the locking system 100 with the secondary ratchet or catch 6 rotated out of engagement with the primary ratchet or catch 4. This can be achieved by an actuator or handle 101 functionally coupled to the secondary ratchet or catch 6, illustrated by the dashed lines in Figure 9. The force from the strike plate 1, as indicated by arrow B, causes the fork bolt or claw 2 to rotate about its fixed pivot 3 and to engage with the primary ratchet or catch. The contact force vector for this interaction, as indicated by arrow C, generates a moment on the primary ratchet around its fixed pivot 5, as indicated by arrow D. Given sufficient strike force in the direction of arrow B, the stop notch or primary ratchet 4 will rotate out of engagement of the fork bolt or claw 2.A further counterclockwise rotation (relative to the view illustrated at least in [Fig.9]) of the secondary stop or ratchet 6 will cause the secondary stop or ratchet 6 to contact the primary stop at point 10, which will cause the primary stop or ratchet 6 to rotate counterclockwise (relative to the view illustrated at least in [Fig.9]) to ensure that the primary stop or ratchet 6 rotates so as to disengage from the fork bolt or claw 2.

[0057] Fig. 10 shows the locking system 100 in a released position.
