    [0001] (a) Field of the Invention [0001]
    [0002] The present invention relates to a dual mode shift lever unit for an automatic transmission, and in particular, to a cable block-locking mechanism for a dual mode shift lever unit having automatic and manual modes, which is capable of reliably locking a cable block at a D range in manual mode. [0002]
    [0003] (b) Description of the Related Art [0003]
    [0004] Recently, high-class automobiles have tended to be equipped with a dual mode transmission mechanism for satisfying driver's whimsical tastes to sometimes take the pleasure of manually shifting the transmission like a sports car, and sometimes to enjoy ride quality of an automatic operation of a high-class sedan. [0004]
    [0005] This kind of dual mode shift unit provides two shift modes, i.e., an automatic mode and a manual mode, such that an indicator panel is formed having a guide groove separating respective mode portions as shown in FIG. 1. [0005]
    [0006] The dual mode shift lever unit comprises a shift lever slidably inserted into the guide groove formed on the indicator panel and a cable block connected to a transmission manual valve by a cable. [0006]
    [0007] Normally when the shift lever unit is in the automatic mode, the shift lever is fixedly connected to the cable block by a projection formed on the shift lever being inserted into a hole formed on one side of the cable block such that the transmission manual valve is responsively operated by shift lever manipulation. [0007]
    [0008] On the other hand, when the shift lever unit is in the manual mode, the shift lever is separated from the cable block by the projection of the shift lever being pulled from the hole of the cable block such that the shift lever freely moves. [0008]
    [0009] In this manual mode, the cable block must be locked at a drive range and the locking is performed by a detent spring formed on one side of the cable block and a detent plate formed on the shift lever unit housing. [0009]
    [0010] However, this conventional locking mechanism for the dual mode shift lever unit has a drawback in that since the locking of the cable block at the drive range is performed by the meager elastic force of a detent spring together with a detent plate, the locking is unreliable during vibration and especially when a vehicle experiences exterior impacts. [0010] SUMMARY OF THE INVENTION
    [0011] The present invention has been made in an effort to solve the above problems of the prior art. [0011]
    [0012] It is an object of the present invention to provide a cable block-locking mechanism of a dual mode shift lever unit which is capable of reliably locking a cable block at a D range during manual mode driving. [0012]
    [0013] To achieve the above object, the cable block-locking mechanism for a dual mode shift lever unit including a shift lever pivotally connected to a pivot shaft in a lever housing via a lever bracket provided at a lower end of the shift lever, a rotation member rotationally mounted on the pivot shaft, and a cable block pivotally mounted on the pivot shaft outside the lever housing, comprises a stud slidably mounted to the cable block for selectively connecting the cable block with the lever housing, a pushrod formed on the lever bracket for depressing the stud so as to release the cable block from the lever housing in an automatic mode, and a return spring mounted around the stud for returning the stud to its place so as to couple the cable block with the lever housing in a manual mode. [0013] BRIEF DESCRIPTION OF THE DRAWINGS
    [0014] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate an embodiment of the invention, and together with the description, serve to explain the principles of the invention. [0014]

    [0018] FIG. 4 is an operational view showing behavior of a cable block-locking mechanism of the dual mode shift lever unit of FIG. 2. [0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
    [0019] A preferred embodiment of the present invention will be described hereinafter with reference to the accompanying drawings. [0019]
    [0020] FIGS. 2 and 3 are perspective views of a dual mode shift lever unit respectively with and without a shift lever housing. [0020]
    [0021] The dual mode shift lever unit [0021] 10 comprises a shift lever 1 pivotally connected to a pivot shaft 4 in a lever housing 3 via a lever bracket 2 provided at a lower end of the shift lever 1 and a rotation member 17 rotationally mounted on the pivot shaft 4 and a cable block 5 pivotally mounted on the pivot shaft 4 outside the lever housing 3. The lever housing 3 is provided with a hole 9 on its wall facing the cable block 5 such that the lever bracket 2 and the cable block 5 interact with each other.
    [0022] The lever bracket [0022] 2 is provided with a pair of arms 8 and 8′ formed on one side in the middle thereof facing the cable block 5 and pivotally connected at its lower end to the rotation member 17 in a vertical direction relative to the longitudinal axis of the rotation member 17 such that the shift lever 1 can pivot in front, rear, left, and right directions in relation to a vehicle's longitudinal direction.
    [0023] The cable block [0023] 5 is provided with a projection 7 corresponding to the arms 8 and 8′ and connected to a manual valve (not shown) of an automatic transmission (not shown) via a cable 6 at its upper end so as to operate the manual valve by shift lever manipulation in the automatic mode in which the lever bracket 2 is locked to the cable block 5 by receiving the projection 7 of the cable block 5 between a pair of arms 8 and 8′ formed on one side of the lever bracket 2.
    [0024] As shown in FIG. 4, the dual mode shift lever unit [0024] 10 has a cable block-locking mechanism. The cable block-locking mechanism comprises a stud 13 having a shape of a mushroom with a stem 13 a and a head 13 b such that the stem 13 a is slidably inserted into a hole formed on the cable block 5 and the head 13 b is received into a hole 9 formed on the lever housing 3, a push rod 11 correspondingly formed on the lever bracket 2 so as to push the stud 13 to a location corresponding to the automatic mode, and a return spring 15 mounted around the stem 13 a of the stud 13 for returning the head 13 b of the stud 13 to the hole 9 when the automatic mode is converted to the manual mode. The stud 13 is provided with a stopper ring 16 formed around an end portion thereof for preventing the stud from being separated from the hole of the cable block 5. The operation of the cable block-locking mechanism according to the preferred embodiment of the present invention will be described hereinbelow.
    [0025] Normally, in the automatic mode, the shift lever [0025] 1 is pivoted in the direction D on the pivot axis P such that the projection 7 of the cable block 5 is fitted between the arms 8 and 8′ of the lever bracket, and at the same time the push rod 11 of the lever bracket 2 pushes the head 13 b of the stud 13. Accordingly, the stud head 13 b is separated from the hole 9 of the lever housing 3 such that the cable block 5 can freely pivot on the shaft 4 according to the shift lever manipulation.
    [0026] On the other hand, if the shift mode is converted from the automatic mode to the manual mode, the shift lever [0026] 1 is pivoted in the direction M on the pivot axis P in the drive range. In this case, the projection 7 of the cable block 5 is separated from the arms 8 and 8′ of the lever bracket, and the push rod 11 of the lever bracket 2 is retreated such that the stud head 13 b is inserted into the hole 9 of the lever housing 3 by the elastic force of the return spring 15. As a result, the cable block 5 engages the lever housing and it is locked in the drive range.
    [0027] As described above, in the dual mode shift lever unit adopting the cable block-locking mechanism of the present invention, since the cable block is locked by the stud which interengages the cable block and the lever housing at the drive range in the manual shift mode, this mechanism provides a reliable lock even when the vehicle experiences exterior impacts. [0027]
    [0028] While this invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
