[0025] Those skilled in the art will appreciate and understand the above and other features and advantages of the invention from the detailed description, drawings and appended claims below. Brief description of the attached figures
[0026] Embodiments of the invention will now be described by way of example only, with reference to the accompanying drawings, in which:
[0027] Figure 1 A vehicle latching linkage system is shown, as well as a partially enlarged portion of the vehicle latching system;
[0028] Figure 2 A cable-protected vehicle latch according to this disclosure is shown;
[0029] Figure 3 The door latch button and cable interface are shown when the latch is in the unlocked state, and the door latch button and cable interface are shown when the latch is in the locked state; and
[0030] Figure 4 The diagram shows the movement of the end of the cable when the gate button is blocked and the latch is switched to the unlocked state. Detailed Implementation
[0031] According to various embodiments of this disclosure, the latch connected to the gate button linkage system provides protection that allows cable movement when an unlocking operation is performed and movement of the gate button is blocked.
[0032] Now for reference Figures 1-4 , Figures 1-4 A vehicle latch linkage system 10 is shown. This document illustrates a latch 12 configured to releasably secure and release a vehicle's hammer. The latch 12 may also include an actuator 16 with a motor configured to operate components of the latch 12 using known techniques. A release cable 20 operates a lever and ultimately actuates a brake lever or pawl of the latch 12, such that, upon actuation of the release cable 20, the hammer releasably secured by the fork bolt or pawl is released. For example, the release cable 20 can be operably connected to an inner release lever 21 or an outer release lever 23 (via... Figure 1 The boxes in the diagram schematically show the inner release lever 21 and the outer release lever 23, which move the cable 20 and ultimately the latch 12 when the release cable 20 is manipulated by the driver, passenger or vehicle system.
[0033] Door latch button 22 is operably connected to the latch lever via door latch cable 26. The door latch button 22 can be conveniently positioned on the inner surface of the door, allowing the driver or passenger of the vehicle to operate it up and down, thus switching the latch 12 between a locked and unlocked state. For example, the door latch button 22 can be located on the inner surface of the door, allowing the driver or passenger to operate it to lock and unlock the latch 12. Therefore, when the door latch button 22 moves up and down in the direction indicated by arrow 28, the door latch cable 26 actuates the lever, causing the latch 12 to switch between a locked and unlocked state due to the movement of the door latch button 22 in the direction indicated by arrow 28.
[0034] Furthermore, in a non-limiting embodiment, the latch 12 can be placed in a locked or unlocked state by moving a lever with an actuator and ultimately moving the gate cable 26 and the gate button 22 operably connected to the gate cable 26. In one embodiment, the gate cable 26 is a rigid metal wire.
[0035] Of course, it should be understood that the various embodiments of this disclosure are applicable to front door and / or rear door vehicle latch linkage systems.
[0036] Now for reference Figures 1-4 , Figures 1-4Embodiments of this disclosure are illustrated. A connector or cable end fitting or gate button interface 30 operably connects a gate button 22 to a gate cable 26. In one embodiment, the gate button 22 has a plurality of threads 32 that engage with threaded openings in the connector or cable end fitting or gate button interface 30. Alternatively, the gate button 22 can be secured to the gate button interface 30 by any other suitable means. The end 34 of the gate cable 26 is slidably received in a slot or elongated opening 36 of the connector or cable end fitting or gate button interface 30. In one embodiment, the slot or elongated opening 36 has an opposite “L” or “J” shape, such that the slot or elongated opening 36 has a vertical portion 38 that connects to a horizontal or lateral portion 40. The vertical portion 38 and the horizontal or lateral portion 40 may have a small angle so that the end 34 of the gate cable 26 can move therein. In other words, in a non-limiting embodiment, the vertical portion 38 and / or the horizontal portion 40 need not be strictly vertical and / or horizontal. Of course, slots or elongated openings 36 with other structures can also be considered, as long as the slot or elongated opening 36 has a vertical portion 38 connected to the horizontal or transverse portion 40.
[0037] The end 34 of the gate cable 26 is configured as a hook 42 to hold the gate cable 26 within the slot or elongated opening 36 as it slides within it. For example, and in a non-limiting embodiment, the hook 42 is shaped as a bend.
[0038] Figure 3 The movement of the door latch button 22 is shown when the latch 12 is moved in the direction of arrow 42 to the unlocked and locked states. The movement of the door latch button 22 relative to a door latch 44 (e.g., a door) inside the vehicle is also shown. In other words, when the door latch button 22 moves in the direction of arrow 42, the door latch button 22 moves both inside and out of the door latch 44. Figure 3 The movement of the door stop button 22 is shown during normal operation or when the door stop button 22 is not obstructed as it moves outward from the door stop 44.
[0039] Now for reference Figure 4 , Figure 4 The diagram shows an attempted movement of the door latch button 22 from the locked position to the unlocked position. However, the movement of the door latch button 22 outward from the door latch 44 in the direction of arrow 46 is obstructed. This could be due to a person's hand or arm blocking the movement of the door latch button 22. Of course, any other object could also impede the movement of the door latch button 22.
[0040] When this occurs, the gate cable 26 can still move in the direction of arrow 46 because the end 34 of the gate cable can move first in the horizontal or transverse portion 40 and then in the vertical portion 38. Arrow 48 illustrates this movement. Therefore, the latch 12 can be unlocked, and if the release lever 21 or 23 is pulled simultaneously, the gate cable 26 will remain in the appropriate position even if the movement of the gate button 22 is obstructed.
[0041] Subsequently, when the latch 12 moves to the locked state, the end 34 of the gate cable 26 moves in the opposite direction to arrow 48, thereby placing it in the locked position. Figure 3 The position shown. Once the gate cable 26 is in this position, the horizontal or transverse portion 40 acts to lock the end 34 of the gate cable 26. Therefore, as long as the movement of the gate button 22 is not obstructed, the movement of the gate cable 26 in the direction of arrow 42 will cause... Figure 3 The movement is shown.
[0042] The figure also shows the gate cable 26 slidably housed in the gate cable sheath 50.
[0043] Therefore, when the gate button 22 moves up and down in the direction indicated by arrow 42, the gate cable 26 actuates the latch lever, causing the latch 12 to switch between a locked and unlocked state, regardless of whether the outward movement of the gate button 22 from the gate 44 is obstructed. This prevents potential damage to the latch 12 caused by obstruction of the outward movement of the gate button 22 from the gate 44 when the release lever of the latch 12 is simultaneously actuated. Thus, protection is provided for the gate cable 26.
[0044] The term “approximately” is intended to include the degree of error associated with a specific number of measurements based on the available equipment at the time of application submission. For example, “approximately” could include a range of ±8%, 5%, or 2% for a given value.
[0045] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” should also include the plural forms. It should be further understood that when the terms “comprising” and / or “including” are used in this specification, the terms specify the presence of the stated feature, integer, step, operation, element, and / or component, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups of elements or components.
