Definitions
- This invention relates to a vehicle latch that can hold a lever, in particular a release lever, during shipping and installation.
- Vehicle latches generally comprise a housing, a ratchet, a pawl, an inside release lever, an outside release lever, an inside locking lever, and an outside locking lever.
- the various levers are operably coupled to the pawl to effect the various functions of the latch. Examples of typical latches are disclosed in United States Patent nos. 4,929,007 and 6,254,148.
- Each of the various levers are operably connected, typically via a Bowden cable or rigid rod, to a respective handle or lever.
- a Bowden cable can be adjusted after the lever is installed.
- a rigid rod cannot be adjusted after the clip connecting the release lever to the rod has been closed. If the release lever is not in the correct position for installation, the attachment of the release lever to the clip will leave the release lever in a less than optimum position. If the release lever is unable to return to the designed rest or ready position, the release lever may block or prevent the locking lever from freely moving preventing the latch from fully locking or unlocking.
- the latch In current production latches for Volkswagen and Audi, the latch is provided with a spring that biases the release lever to the designed rest or ready position to ensure that the latch can be properly installed. Once the latch is installed and attached to the rigid rod to operably connect the release lever to the outside handle, the spring is disengaged from the release lever, allowing normal operation of the latch. The spring can be re-engaged for re- installation after service. However, in normal operation, the spring provides no useful function.
- a latch having a housing having a detent positioned to retain a spring coupled to a lever and thereby selectively position the lever in an "install" position during shipping and installation.
- a vehicle latch which includes a housing having a detent and a stop.
- a lever having an abutment is pivotally connected to the housing.
- a spring having a coil section, a tail portion and an opposite portion is mounted in the housing. The opposite portion biases the lever to a predetermined position.
- the tail portion is moveable from an install position to an operational position. In the install position the tail portion engages the detent and the lever abutment so as to locate the lever at the predetermined position. In the operational position the tail portion is biased to engage the stop when the lever is first pivoted away from the predetermined position.
- the predetermined position of the lever in the install position is a position in which the lever engages the housing.
- the predetermined position of the lever in the operational position is the same position of the lever as in the install position.
- the opposite end of the spring engages the lever and provides a greater force to bias the lever to the predetermined position when the tail portion is in the install position than when the tail portion is in the operational position.
- the tail portion of the spring is removable from the detent upon application of a force on the lever, said force being greater than the bias force on the lever provided by the spring.
- a vehicle latch having a housing with a detent and a stop.
- a lever is pivotally connected to the housing and is movable from a ready position engaging the housing to an active position pivoted away from the housing.
- a spring extends from the lever to the housing applying a biasing force to the lever urging the lever to the ready position.
- the spring has a tail portion, a coil section and an opposite end. The opposite end engages the lever to provide the biasing force which moves the lever to the ready position.
- the tail end is moveable to engage either the stop or detent. When the tail end engages the detent, the tail end also engages the lever and the biasing force holding the lever in the ready position is increased.
- the tail end is removable from the detent to engage the stop when the lever is first pivoted away from the ready position, disengaging the lever from the tail end and thus reducing the biasing force on the lever.
- Figure 1 is a perspective view of latch of the present invention with the lever in a "ready” position and the tail end of the spring in an “install” position;
- Figure 2 is perspective view of the latch of Figure 1 with the lever in a first pull or "active" condition
- Figure 3 is a perspective view of the latch of Figure 1 , with the lever in the ready position and the tail end of the spring in an "operational" condition.
- Figure 1 illustrates a latch 10 of the present invention.
- the latch 10 The latch
- latch 10 is of conventional construction and design.
- latch 10 can have four levers, an inside and outside locking lever and an inside and outside release lever.
- the invention could be applied to any of these levers, the invention is preferably applied to the outside release lever for an operative connection to an outside door handle.
- the latch 10 has a lever 12 that is pivotally connected to the latch 10 at pin 14.
- a spring 16 extends between the lever 12 and the housing 18 of the latch 10.
- Spring 16 has an elongated tail portion 20 extending from a coil section 22 wound about the pin 14, terminating in an opposite end 24. End 24 engages a tab 26 of lever 12.
- the tail portion 20 of the spring 16 engages a connecting end 28 of the lever 12 at an abutment or tab 30.
- Housing 18 has a detent 32, preferably formed from two wedge shaped parts 32a, 32b molded in the face of the housing, and a stop 34.
- the detent 32 is located such that the tail portion 20 extends from the coil section 22 to engage tab 30 while tab 30 engages a stop 36 formed in the housing.
- Detent 32 is sized to firmly hold the tail portion 20 in this position, namely, an "install" or shipping position. In this position, the lever 12 cannot be moved away from the stop 36 unless a significant force is applied sufficient to dislodge the tail portion 20 out of the detent 32.
- the spring 16 also provides a bias force to urge the lever 12 against stop 36. In this position, the connecting rod or Bowden cable can be attached to the connecting end 28 of the lever.
- the handle is operated, pulling the lever 12 in the direction of arrow A (Fig. 2) from a ready position to an active position.
- the pulling force will urge the tail portion 20 over the detent 32 whereupon spring bias will snap the tail end 20 into an operational position, engaging the stop 34, as shown in Fig. 2.
- the spring operating through opposite end 24, will urge the lever 12 back to abut stop 36, as shown in Fig. 3.
- the force required to activate the lever 12 is equivalent to a biasing force provided by the opposite end 24 of spring 22, consistent with normal operation of the latch 10.
- the spring 16 is contracted to a greater extent as shown in Fig. 1 thus providing a greater force acting on lever 12 so as to keep it in the install or shipping position.
- the tail portion 20 can be returned to the shipping position by manually urging the-tail portion 20 against the rotation of the coil section 22 and over the wedge of detent 32.
- the tail end 20 can be returned if the latch or the release handle is required to be serviced.
