DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0016] 1, a case 12 of a door lock release device 11 of the present invention is fixed to the inside of a vehicle door 10, and an inside door handle 13 that is operated from inside the vehicle is journaled on this case 12. A key cylinder lock 14 that is turned with a predetermined key is attached to the outside of the door 10. Furthermore, the door 10 is provided with a door lock device 15 that locks the door 10 in a closed state, and this door lock device 15 is designed to be unlocked by either the inside door handle 13 or the key cylinder lock 14 being released.

[0017] The configuration will be explained in detail below.

[0018] 2 to 5, the case 12 is a rectangular parallelepiped that is long in the longitudinal direction of the vehicle, and support pieces 12a protruding from the four corners are fixed to the door 10 by bolts or the like.

[0019] On the front side (vehicle compartment side) of this case 12, there is a first front chamber 17 located above the front of the case 12, and on the back side of the case 12, there is a rear chamber 19 located at the rear of the case 12 and a second front chamber 18 located below the first front chamber 17.

[0020] In addition, an intermediate chamber 20 that opens to the front and back surfaces of the case 12 is provided in the middle of the case 12 in the front-rear direction.

[0021] Furthermore, the case 12 is provided with a partition wall 21 that separates the first front chamber 17 and the middle chamber 20, and a protruding wall 22 that rises from the bottom surface of the rear chamber 19 and faces the middle chamber 20.

[0022] The partition wall 21 has a support wall protruding toward the intermediate chamber 20. 2 3 is protruding, and this supporting wall 2 Between the case 3 and the upper wall of the case 12, a pair of upper and lower bosses 13a of the inside door handle 13 arranged in the first front chamber 17 are supported by a support shaft 24.

[0023] Thus, the inside door handle 13 can be rotated toward the passenger compartment from an original position where its surface is flush with the surface of the case 12, and a return spring 25 made of a torsion coil spring that always urges the inside door handle 13 to its original position is attached to the support shaft 24. The original position of the inside door handle 13 is determined, for example, by abutting the inner surface of the inside door handle 13 against the tip of the partition wall 21 (see Figure 5).

[0024] This inside door handle 13 is integrally formed with an operating arm 27 that protrudes from its base toward the intermediate chamber 20 side.

[0025] As shown in Figures 4, 5, 7 and 8, the rear chamber 19 is provided with a mutual separation mechanism 29 consisting of a driven slider 30 and a first driving slider 31 and a second driving slider 32 arranged above and below the driven slider 30 with a small gap therebetween. , adjacent to the inside door handle 13 It is arranged.

[0026] The driven slider 30 is slidable along the longitudinal direction of the vehicle, and in order to guide this sliding, a pair of slide protrusions 34 formed on the driven slider 30 are slidably engaged with a pair of rail grooves 33 formed on the bottom surface of the rear chamber 19 and extending along the longitudinal direction of the vehicle. Furthermore, in order to ensure the sliding while preventing the driven slider 30 from tipping over and coming off the rail grooves 33, both ends of a guide shaft 53 that slidably passes through the guide hole 52 of the driven slider 30 in parallel with the rail grooves 33 are fixedly supported by the convex wall 22 and the rear end wall 19a of the rear chamber.

[0027] The driven slider 30 is connected to the door lock device 15 (FIG. 1) via a first cable 41 that passes through the rear end wall 19a of the rear chamber 19. Reference numeral 41a denotes a guide tube for the first cable 41.

[0028] Thus, the driven slider 30 can pull the first cable 41 and unlock the door lock device 15 by moving from the original position determined by the locked door lock device 15 in a predetermined unlocking direction A toward the front of the vehicle.

[0029] Meanwhile, in order to guide the sliding of the first and second drive sliders 31, 32 along the longitudinal direction of the vehicle, slide protrusions 34, 36 formed on the first and second driven sliders 31, 32, respectively, are slidably engaged with rail grooves 35, 37 formed on the bottom surface of the rear compartment 19. Furthermore, in order to ensure the sliding while preventing the first and second drive sliders 32 from tipping over and coming off the rail grooves 35, 37, a case cover 40 is attached to the case 12 so as to cover the first and second drive sliders 31, 32.

[0030] When attaching the case cover 40, as shown in Figure 4, a pair of claws 40a at the front end of the case cover 40 are engaged with receiving holes 46 provided in the case 12, and a pair of protrusions 40b at the rear end of the case cover 40 are fixed to the case 12 with screws 43.

[0031] Shim walls 40c for adjusting the gaps between the first and second drive sliders 31, 32 and the upper and lower side walls 19b of the rear chamber 19 are integrally formed on the case cover 40.

[0032] As shown in Figures 3, 6 and 7, the front end of the first driving slider 31 is provided with a rectangular connecting hole 31a into which the operating arm 27 of the inside door handle 13 is inserted, and the rear end is provided with a first hook 31b that abuts and engages with one side of the pressure-receiving surface 30a at the rear end of the driven slider 30 in a releasable manner.

[0033] When the driven slider 30 is in its original position, the original position of the first driving slider 31, which simply abuts the first hook 31b against its pressure-receiving surface 30a, is determined by the inside door handle 13, which is held in its original position by the return spring 25.

[0034] 6, a cable connection boss 32a is provided at the front end of the second drive slider 32, and a second cable 42 extending from a rotating part (not shown) of the key cylinder lock 14 (FIG. 1) is connected to this cable connection boss 32a. At this time, this second cable 42 is arranged so as to pass through the second front chamber 18 by penetrating the front end wall 18a of the second front chamber 18. Reference numeral 42a denotes a guide tube for this second cable 42.

[0035] Further, a second hook 32b (see Figs. 2 and 6) is provided at the rear end of the second driving slider 32, which releasably abuts and engages with the other side of the pressure-receiving surface 30a of the driven slider 30. The original position of the second driving slider 32, where the second hook 32b is simply abutted against the rear end surface of the driven slider 30 in the original position, is determined by a return spring (not shown) of the key cylinder lock 14.

[0036] Next, the operation of this embodiment will be described.

[0037] In order to unlock the door lock device 15 that locks the door 10 in a closed state, first, for example, the inside door handle 13 is rotated from its original position toward the inside of the vehicle, causing the operating arm 27 to pull the first drive slider 31 toward the front of the vehicle, and the first hook 31b of this first drive slider 31 presses against the pressure-receiving surface 30a of the driven slider 30, causing the driven slider 30 to be driven in the specified release direction A, pulling the first cable 41 and unlocking the door lock device 15.

[0038] During this time, the second drive slider 32 remains in its original position. In other words, the second drive slider 32 is separated from the first drive slider 31 and the driven slider 30, and does not interfere with the movement of the driven slider 30 in the release direction A, and does not become a load. Therefore, the release operation of the inside door handle 13 can be performed easily, and the operability is good.

[0039] In addition to the above, when the key cylinder lock 14 is unlocked with a specified key, the rotating part of the key cylinder lock 14 pulls the second drive slider 32 toward the front of the vehicle via the second cable 42, and the second hook 32b of this second drive slider 32 presses the pressure-receiving surface 30a of the driven slider 30, driving the driven slider 30 in a specified release direction A, thereby pulling the first cable 41 and unlocking the door lock device 15.

[0040] In this case, the first drive slider 31 remains in its original position. In other words, the first drive slider 31 is separated from the second drive slider 32 and the driven slider 30, and does not interfere with the movement of the driven slider 30 in the release direction A, and does not become a load. Therefore, the release operation of the key cylinder lock 14 can be performed easily, and the operability is also good.

[0041] In this way, when either the inside door handle 13 or the key cylinder lock 14 is released, the other can be left in its original position, thereby avoiding the burden of releasing one of them, and improving the operability of both the inside door handle 13 and the key cylinder lock 14.

[0042] Furthermore, the mutual separation mechanism 29 consisting of the driven slider 30, the first driving slider 31 and the second driving slider 32 has a small number of components, so that it is possible to provide a door lock release device that is simple in structure and inexpensive.

[0043] Furthermore, a guide shaft 53 is provided in the case 12 that houses the mutual separation mechanism 29 to guide the driven slider 30 so that it can slide along the release direction A, so that the driven slider 30 can always be maintained in a stable position without tilt. Therefore, when either the inside door handle 13 or the key cylinder lock 14 is released, the driven slider 30 can be smoothly driven in the release direction A via the first or second drive slider 31, 32, thereby improving the operability of both the inside door handle 13 and the key cylinder lock 14.

[0044] Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various design modifications can be made without departing from the scope of the present invention as set forth in the claims. For example, the inside door handle 13 can be replaced with an outside door handle disposed on the outside of the door 10. [Explanation of symbols]
