Abstract

A recombinant lentiviral vector expression system comprises a first vector that comprises a nucleic acid sequence of at least part of the Equine Infectious Anemia Virus (EIAV) genome. The vector contains at least one defect in at least one gene encoding the EIAV structural protein, but is preferably a gag/polexpression vector. The expression system further comprises a second vector, also comprising a nucleic acid sequence of at least part of the Equine Infectious Anemia Virus (EIAV) genome, and additionally containing a multiple cloning site wherein a heterologous gene may be inserted. The expression system also comprises a third vector which expresses a viral envelope protein. The first and third vector are packaging signal- defective. When the expression system is transfected into a lentivirus-permissive cell, replication-defective EIAV particles may be produced, which particles are useful in delivering heterologous genes to a broad range of both dividing and non-dividing cells.

In general, a conventional door lock device for automobiles is divided into an actuator unit 10 and a door latch assembly unit 50 interlocked with the actuator unit 10 as shown in FIGS. 6A and 7A. It is composed of each detailed component and its operation state are as follows.

The actuator portion 10 includes a motor 12 having a connector 30 that serves as a power supply, a screw shaft 22 that is driven by receiving power from the connector 30, and the motor 12. Helical-type first gear 16 that rotates in engagement with the screw shaft 22 of the crankshaft, and a second gear 18 of the spur gear type that is coaxially fixed and rotated simultaneously with the first gear 16, The third gear 20 in the form of a spur gear that meshes with the second gear 18 to receive the rotational force, and is fixed coaxially under the third gear 20 to the rotational force of the third gear 20. It consists of the cam 26 which moves by a predetermined angle by this.

On the other hand, the projection 52 is integrally formed on the bottom of the third gear 20, and one surface of the cam 26 provided coaxially with the third gear 20 is formed as a concave surface. The projection 52 is positioned in such a manner that it is inserted into the concave surface.

In addition, the components of the actuator unit 10 listed above are installed inside the case 34, and the rear surface of the case 34 has a lever 38 that moves at the same angle according to the movement angle of the cam 26. ) Is connected.

In addition, the door latch assembly 50 is connected to the lever 38 and moved to the same angle as the angle of the lever 38, the first link 54, and one side end of the first link 54 is predetermined The second link 56 is interlocked at an angle of the slide groove is inserted into the projection formed on the upper side of the second link 56 and a slide groove is formed at the lower end so as to slide up and down, so as to press the lever lever 44 The third link 58 having a pressing end 46 on one side of the portion, and the left end is fixed to the upper end of the third link 58 and the right end is pressed by the lever 42 for connecting the door handle inside the door. The fourth link 60 is located, the upper end of the third link 58 and the right end of the fourth link 60 is composed of a rod external handle connecting rod 40 is fixed to the bottom of the point shared with each other It is.

6A and 7A show an unlocked state of a conventional door lock device, and FIGS. 6B and 7B show a locked state of a door after an operation of the conventional door lock device. Referring to the operation of the conventional door lock device for a vehicle having a configuration as follows.

First, when the key is inserted into the door key groove of the door handle assembly and the lock position of the remote control is pressed or when the lock button of the remote controller is pressed, the power source has a screw shaft 22 via the connector 30 of the actuator unit 10 ( 12).

Next, the screw shaft 22 rotates at the same time as the motor 12 is driven, and the second gear 18 coaxial with the helical first gear 16 engaged with the screw shaft 22 is rotated. Will rotate simultaneously.

Subsequently, the third gear 20 in the form of a spur gear that receives the rotational force of the second gear 18 rotates. At this time, the protrusions 52 integrally formed on the bottom of the third gear 20 are simultaneously rotated. While rotating, the concave side surface of the cam 26 installed on the coaxial axis is pushed and pushed.

Therefore, as shown in FIG. 6B, the cam 26 is rotated by a predetermined angle while being pushed by the protrusions 52 of the third gear 20. It is rotated to the locked position, and thus the door is locked by the interlocking action of each door latch assembly 50 to be described later.

Herein with reference to Figures 7a and 7b attached to the interlocking action of the door latch assembly in the locked state as follows.

As described above, when the cam 26 has a predetermined angle and is moved to the locked position, as shown in FIG. 7B, the lever 38 mounted on the back of the case 34 also moves at a predetermined angle. The first link 54 connected to the lever 38 also rotates at a predetermined angle, and at the same time, the right end of the second link 56 is pulled by the first link 54 to move downward.

At the same time, the left end of the second link 56 is moved upward, and the third link connecting protrusion formed in the middle of the second link is moved to the right.

At this time, the projection of the second link 56 is inserted into the slide groove of the lower end of the third link 58, the third link is slidably connected, bar of the projection of the second link 56 By the right movement, the lower end of the third link 58 is also pulled to the right to move.

On the other hand, in the door unlock state by operating the button lock knob installed on the upper surface of the door trim to move the rod external handle connection rod 40 up and down, or by operating the door handle lever for connecting the door inner handle ( When 42 is moved at a predetermined angle, the fourth link 60 connected to the upper end of the third link 58 pushes the third link 58 downward, as shown in FIG. 7A. Similarly, since the pressing end 46 formed in the middle portion of the third link 58 is located at the position coincident with the right end of the foul lever 44, the pressing end when the third link 58 moves downward. 46 presses the right end of the fouling lever 44 and at the same time the latch (not shown) in which the striker 48 is rotated and detached is released, thereby opening the door.

On the contrary, when the door is locked as described above, the lower end of the third link 58 is pulled by the right movement of the protrusion of the second link 56 and moved to the right, and the third link 58 is moved. Since the pressing end 46 of the third link 58 is also moved to the right side, the pressing end 46 of the third link 58 is in a state in which it is inconsistent with the fouling lever 44.

Accordingly, when the third link 58 moves downward by the vertical movement of the rod external handle connecting rod 40, the slide groove at the bottom of the third link 58 protrudes from the second link 56. Only slides up and down along this time, since the pressing end 46 of the third link 58 is not able to press the fouling lever 44, the door lock state (a state in which the striker is latched) is maintained.

In addition, while the door inner handle connecting lever 42 rotates at a predetermined angle, the right end of the fourth link 60 is pushed upward while the other end of the fourth link 60 is moved downward. Similarly, when the third link 58 is pressed down by the downward movement of the other end of the fourth link 60, the pressing end 46 of the third link 58 is in a mismatched state. Door lock status (striggered latch) remains unchanged.

However, the conventional door locking device having the configuration and operation state as described above has the following problems.

When the door is locked, push a tool such as steel wire into the gap between the door panel and the glass window and make several round trips. At any moment, when the end of the steel wire presses the first link bar in the door lock position, the first link bar In the reverse direction (door unlocking direction) and at the same time the lever connected to the first link bar also rotates in the door unlocking direction, the cam inside the case also rotates in the door unlocking direction, the door lock is released.

Thus, there was a problem of opening the door and theft of car audio, various valuables, etc. in the room.

Therefore, the present invention has been made in order to solve the above problems, by installing a separate motor and a stopper for linear reciprocating motion by the rotational movement of the motor inside the actuator unit case, move to the door lock position By limiting the reverse rotation of the cam by moving the stopper linearly to one side of the cam, the door cannot be opened unless the stopper is released from one side of the cam in the locked position, thus reducing the risk of theft accident. It is an object of the present invention to provide a double locking device of a car door so as to prevent it.
