An interior manually operated handle for operating a power door on a vehicle is typically configured to be operated with one hand. Utilizing a single hand, the user moves the handle from an initial non-actuating position, to an actuating position that causes the door to open or close under power. Once the user releases the handle, the handle is automatically returned from the actuating position back to the initial non-actuating position.
This one-handed operation of the handle to open the power door may be convenient for operating the door in a non-emergency situation, where power is still being supplied to the door for power assisting movement of the door from a closed position to an opened position. However, it may not be convenient in an emergency situation, such as where power is not being supplied to the door to assist its opening, and thus moving the door from the closed position to the opened position could be completely dependent upon the strength of the user to move the door, which may be quite heavy and cumbersome to move.
In these emergency situations however, where no power is being supplied to the door, one of the user's hands must be kept on the biased handle to hold it in the actuating position so as to actuate a latch to release the door from the closed position, while at the same time the user must use the other hand to push the door away from the closed position towards the opened position. This single-hand actuation of the handle while simultaneously pushing the door open with the other hand is necessary because, if the handle is instead released before the door is moved from the closed position, then the latch may re-engage an anchor and not release the door from the closed position. Furthermore, if the door is initially moved from the closed position but accidentally returns the closed position, such as if the vehicle is on an inclined surface causing the door to swing or roll closed, then the latch may re-engage the anchor, and thus require another operation of the handle for its release from the anchor.
If the door is heavy or otherwise difficult to open, then using only one hand to push the door may therefore not result in the door being opened so as to allow the user to exit the vehicle, which could prove consequential in an emergency situation. Using two hands to push the door could help in opening the door enough to allow the user to leave the vehicle. However, this is always not possible, especially at the start of the door-opening process when one hand has to be used to operate the handle to release the door from the closed position.
According to one aspect, an emergency mechanism manually opens a powered door that moves between a closed position and an opened position during a powered operation of the door. The door includes a hold-close latch that holds the door in the closed position and is actuated during the powered operation to release the door from the closed position. The emergency mechanism includes a handle operatively connected to the hold-close latch. The handle is manually movable by a user between a non-actuating position that does not actuate the hold-close latch such that the hold-close latch holds the door in the closed position, and an actuating position that actuates the hold-close latch to release the door from the closed position. When moved to the actuating position, the handle locks in the actuating position.
According to another aspect, a powered door moves between a closed position and an opened position during a powered operation of the door. The door includes a hold-close latch and a handle. The hold-close latch holds the door in the closed position and is actuated during the powered operation to release the door from the closed position. The handle is operatively connected to the hold-close latch. The handle is manually movable by a user between a non-actuating position that does not actuate the hold-close latch such that the hold-close latch holds the door in the closed position, and an actuating position that actuates the hold-close latch to release the door from the closed position. When moved to the actuating position, the handle is held in the actuating position.
The present invention relates to an assembly that allows for pushing open a door, e.g. a door of a vehicle, using two hands. The invention includes an emergency mechanism, including a manually operated emergency handle for manually opening a powered door. The handle can be operated by a user with one hand. When operated by the user, the handle is moved from an initial non-actuating position to an actuating position so as to actuate a latch of the door that releases the door from a closed position. When moved to the actuating position, the handle is held in the actuating position, which causes the continual actuation of the latch (e.g. holds the latch open) so that the door cannot be held by the latch in the closed position. Because the handle is held in the actuating position and the latch therefore cannot hold the door in the closed position, a user can let go of the handle and then utilize both hands to push open the door from the closed position to an opened position. Use of both hands allows the user to exert more power to open the door, which may make opening the door easier, especially if the door is heavy or otherwise difficult to move to the opened position.
With reference to the figures, a double door assembly 2 is shown in
When the front door 4 is closed (i.e. is in a closed arrangement) and the rear door 8 is closed (i.e. in a closed position), a flange 12 or other portion of the rear door 8 may overlap the front door along their interface 14 so that the flange 12 or other portion of the rear door 8 overlaps a portion of the front door 4 from a perspective exterior to the vehicle 6 (See
The invention includes a first opening and closing assembly 16, a first latch 18 (a “hold-close latch”), a second latch 20 (“hold-open latch”), a first cable 22, a second cable 24, and optionally a third cable 26 operatively connecting the first assembly 16 to the first latch 18. While the invention is discussed with respect to the rear door 8, it is not limited to this configuration and can also be applicable to the front door 4 or to other doors, for example, to a single door.
The first assembly 16 is for opening and closing the rear door 8. The first cable 22 operatively connects the first assembly 16 to the first latch 18. The first assembly 16 can be operated to pull the first cable 22 to actuate the first latch 18. The first cable 22 is pulled away from the first latch 18 and toward the first assembly 16. The second cable 24 operatively connects the first assembly 16 to the second latch 20. The first assembly 16 can be operated to pull the second cable 24 to actuate the second latch 20. The second cable 24 is pulled away from the second latch 20 and toward the first assembly 16
When the rear door 8 is in the closed position (see
When the rear door 8 is in the opened position (see solid lines in
The latches 18, 20 and anchors 48, 50 are not particularly limited, and the latches 18, 20 may engage the respective anchors 48, 50 mechanically, magnetically, or otherwise. Actuation of the latches 18, 20 may include moving (e.g. opening the latches), manipulating, or changing a state of the latches 18, 20 such that they disengage the respective anchor 48, 50.
The front door 4 may include a second opening and closing assembly 28 for opening and closing the front door 4; a third latch 30 for holding a bottom of the front door 4 in a closed arrangement (see
The first assembly 16 includes a base plate 52, a first lever 54, a second lever 56, a handle 80, a powered actuator 60 (e.g. motor), and a lock 62. The base plate 52 is mounted on the rear door 8. The first lever 54, the second lever 56, and the handle 80 are rotatably mounted to the base plate 52, and may be coaxially mounted to the base plate 52 at a shared/common axis 64. The first cable 22 operatively connects the first lever 54 to the first latch 18. When the first lever 54 is rotated relative to the base plate 52 in a first rotational direction (R1), the first lever 54 pulls the first cable 22, thus actuating the first latch 18. Although the first rotational direction is shown to be in a counter-clockwise direction, this is not necessary and the first rotational direction may be in a clockwise direction. The second cable 24 operatively connects the second lever 56 to the second latch 20. When the second lever 56 is rotated relative to the base plate 52 in the first rotational direction, the second lever 56 pulls the second cable 24, thus actuating the second latch 20. The rotation of the second lever 56 in the first rotational direction causes the rotation of the rotation of the first lever 54 in the first rotational direction. The rotation of the first lever 54 in the first rotational direction does not cause the rotation of the second lever 56 in the first rotational direction.
The rear door 8 and first assembly 16 have a powered operation and a manual (e.g. emergency) operation.
Powered Operation
Referring now to
During the powered operation, the first assembly 16 operates under power to actuate the first and second latches 18, 20 and thus release the rear door 8 from the closed position or release the rear door 8 from the opened position. The rear door 8 is then able to be moved under power from the just-released position (i.e. opened position or closed position) toward the other position. For this purpose, the first assembly 16 includes the powered actuator 60 (
The actuator 60 operates under power to pull the first cable 22 and the second cable 24 to release the rear door 8, and then move the rear door 8 between the open and closed positions. The actuator 60 may be connected to or include a power source for powering its operation, e.g. connected to a vehicle power source or include a battery. The actuator 60 may include a port 66 (
The actuator 60 operates to rotate the second lever 56 in the first rotational direction. The actuator 60 includes an arm 72 that engages an arm 74 of the second lever 56. Movement of the arm 72 of the actuator 60 causes rotational movement of the second lever 56 in the second rotational direction (R2, which is opposite from R1) by engagement with the arm 74 of the second lever 56. This rotation of the second lever 56 pulls the second cable 24, thus actuating the second latch 20. This rotation of the second lever 56 also causes the first lever 54 to rotate in the first rotational direction by the second lever 56 engaging the first lever 54 at a joint 76 between them. This rotation of the first lever 54 pulls the first cable 22, thus actuating the first latch 18.
When the rear door 8 is released from the open or closed positions in the powered operation, the rear door 8 may be moved under power away from the just-released opened position or closed position and toward the other position, e.g. by a motor and cable assembly (not shown).
When the rear door 8 is released from the closed position and from the opened position, both the first and second latches 18, 20 are actuated. When released from the closed position, the rear door 8 is then moved away from the closed position such that first latch 18 is spaced from the first anchor 48 and can no longer engage the first anchor 48 to hold the rear door 8 in the closed position. When the rear door 8 is released from the opened position, the rear door 8 is then moved away from the opened position such that second latch 20 is spaced from the second anchor 50 and can no longer engage the second anchor 50 to hold the rear door 8 in the opened position.
When moved away from the opened position and from the closed position, the actuator 60 is then deactivated, which allows the first lever 54 and the second lever 56 to rotate in the second rotational direction (R2) so that the levers 54, 56 no longer pull the cables 22, 24 and no longer actuate the latches 18, 20.
The rotation of the first lever 54 in the second rotational direction may be caused by a biasing member, e.g. by a spring 68, that urges the first lever in the second rotational direction. The joint 76 allows the first lever 54, while it is rotating in the second rotational direction, to engage the second lever 56 and cause the second lever 56 to also rotate in the second rotational direction. The first lever 54 includes a stopper 78 that stops further rotation of the first lever 54 in the second rotational direction, e.g. by engaging with a portion of the base plate 52.
When the second latch 20 is no longer being actuated, the second latch 20 is then able to re-engage the second anchor 50 if and when the rear door 8 is moved to the open position, so as to again hold the rear door 8 in the opened position. When the first latch 18 is no longer being actuated, the first latch 18 is then able to re-engage the first anchor 48 if and when the rear door 8 is returned to the closed position so that the first latch 18 again can hold the rear door 8 in the closed position.
Manual Operation
During the manual operation (e.g. when there is no powered operation of the rear door 8 or first assembly 16, such as in an emergency situation), a user manually operates the first assembly 16 to actuate only the first latch 18 to thereby release the rear door 8 from the closed position. The user is then able to move the rear door 8 away from the closed position and toward the open position.
For this manual operation, the first assembly 16 includes the manually operated handle 80 that is operatively connected to the first latch 18, and can be manually operated by the user using their hand or finger(s). Manual operation of the handle 80 includes moving the handle 80 from the initial non-actuating position, which does not actuate the first latch 18, to the actuating position, which does actuate the first latch 18.
With reference to
The handle 80 is mounted to the first assembly 16 and is operatively connected to the first lever 54. Moving the handle 80 to the actuating position causes the first lever 54 to rotate in the first rotational direction. The handle 80 may be rotatably mounted to the first assembly 16, e.g. at the axis 64, such that rotation of the handle in the first rotational direction causes the first lever 54 to rotate in the first rotational direction to pull the first cable 22 and actuate the first latch 18, which thus releases the rear door 8 from the closed position.
When the first latch 18 is actuated in the manual operation, the first latch 18 remains actuated until a subsequent powered operation of the first assembly 16. As such, the first latch 18 is unable to engage the first anchor 48 to hold the rear door 8 in the closed position until a subsequent powered operation of the first assembly 16 is executed. The user is then able to use both hands to push the rear door 8 to the opened position as schematically depicted in
The first assembly 16 includes the lock 62, which is operatively connected to the handle 80 and operates to hold/lock the handle 80 in the actuating position. Having the handle 80 being held/locked in the actuating position causes the first latch 18 to be actuated and remain actuated until the handle 80 is returned to the non-actuating position.
The lock 62 is mounted on the first assembly 16, and is operatively connected, e.g. rigidly connected, to the handle 80 such that movement of the handle 80 causes a corresponding movement of the lock 62 and vice versa. The lock 62 may thus be rotatably mounted to the first assembly 16, e.g. at the axis 64. Manual rotation of the handle 80 in the first rotational direction causes the lock 62 to also rotate in the first rotational direction from an initial position (
The first latch 18 thus remains actuated, making the first latch 18 unable to engage the first anchor 48 even if the rear door 8 is in the closed position. As such, the first latch 18 is unable to hold the rear door 8 in the closed position. This allows the user to use both hands to push the rear door 8 from the closed position, from which it was just released, toward the opened position. This also does not require the user to use one hand to operate the handle 80, and simultaneously use the other hand to push open the rear door 8. Using both hands to push open the rear door 8 makes opening the rear door 8 easier in a non-powered (e.g. emergency) manual operation of the rear door 8.
In the manual operation of the rear door 8 and first assembly 16, operation of the handle 80 does not cause an operation of the second lever 56. This is because the first lever 54 can disengage from the second lever 56 at the joint 76, and thus allows the first lever 54 to be rotated in the first rotational direction without rotating the second sever 56 in the first rotational direction. As such, the second cable 24 is not pulled and the second latch 20 is not actuated during the manual operation. When the user pushes the rear door 8 to the opened position, the second latch 20 is thus able to engage the second anchor 50 (
The lock 62 is held in the locking position and the handle 80 is held in the actuating position until a subsequent powered operation of the first assembly 16, at which point a lock release 96 releases the lock 62 from the locking position and thus releases the handle 80 from the actuating position. The lock 62 may be biased by a biasing member, e.g. a spring 70, which urges the lock back to the initial position.
The lock release 96 may include an unlocking arm 98 of the second lever 56. When the second lever 56 is operated in the subsequent powered operation to rotate in the first rotational direction, the unlocking arm 98 engages/contacts the swinging arm 92 of the lock 62 to push the swinging arm 92 out of the locking position, thus allowing the lock 62 to rotate in the second rotational direction under urging from the spring 70 back to the initial position, which thereby allows the handle 80 to rotate back to the non-actuating position under urging from the spring 68, which causes the first latch 18 to be not actuated and thus allows the first latch 18 to engage the first anchor 48 if the rear door 8 is moved to the closed position. Moreover, rotation of the second lever 56 in the subsequent powered operation also causes the second cable 24 to be pulled, thus actuating the second latch 20, which at that point may be engaging the second anchor 50 to hold the rear door 8 in the opened position. When actuated in the subsequent powered operation, the second latch 20 disengages the second anchor 50, and thus releases the rear door 8 from the closed position allowing the rear door 8 to be moved from the closed position towards the opened position.
The present invention thus includes an assembly configured to pull certain cables during a powered operation and others during a manual (emergency) operation. The system decouples the operation of levers for certain latches of the sliding door assembly. The assembly is configured such that a cable for a hold-close latch is pulled for both a powered operation and a manual (emergency) operation. However, a cable for a hold-open latch is not pulled during the manual (emergency) operation and is only pulled during the powered operation. Further, during the manual operation an actuation handle is held in the actuating position, and the handle is reset to a non-actuating position during a subsequent powered operation.
