Abstract

A clearance adjusting device for a cable includes a wire having a first side connected to a drive mechanism and a second side connected to an operation mechanism to enable the drive mechanism to be operated in conjunction with the operation mechanism when the wire is moved in an other direction by operation of the operation mechanism, an elastic part having a first end portion connected to the wire and formed to be elastically compressible, and a clearance elimination mechanism fixed to a base, with the wire and the elastic part embedded therein while the wire passes therethrough, in a state where a second end portion of the elastic part is connected to and supported by the clearance elimination mechanism, such that the wire receives an elastic force provided in the other direction toward the operation mechanism by the elastic part.

First claim

What is claimed is:

1 . A clearance adjusting device for a cable, the device comprising:
a wire having a first side to which a drive mechanism is connected and a second side to which an operation mechanism is connected to enable the drive mechanism to be operated in conjunction with the operation mechanism when the wire is moved in another direction by operation of the operation mechanism; an elastic part having a first end portion connected to the wire and formed to be elastically compressible; and a clearance elimination mechanism fixed to a base, with the wire together with the elastic part embedded therein while the wire passes therethrough, in a state where a second end portion of the elastic part is connected to and supported by the clearance elimination mechanism, such that the wire receives an elastic force provided in the other direction toward the operation mechanism by the elastic part to eliminate a clearance between the drive mechanism and the wire when the clearance is generated.

2 . The device of claim 1 , wherein the clearance elimination mechanism includes a fixing socket mounted on and fixed to the base, having a hollow region to allow the wire to pass therethrough, and having a seating space for the elastic part to be seated therein such that the second end portion of the elastic part is supported by a first end of the seating space.

3 . The device of claim 2 , wherein the wire has a hook portion bent to hook the first end portion of the elastic part and the fixing socket has a connection portion bent to hook the second end portion of the elastic part at the first end of the seating space to connect the wire to the fixing socket via the elastic part.

4 . The device of claim 2 , wherein the seating space in the fixing socket is formed to extend longer than a length of the elastic part when tensioned.

5 . The device of claim 2 , wherein the clearance elimination mechanism further includes a length adjustment socket mounted to be movable on the fixing socket in a length direction, while allowing the wire to pass therethrough, to adjust the clearance between the drive mechanism and the wire according to a position to which the length adjustment socket moves.

6 . The device of claim 5 , wherein the length adjustment socket includes:
a conduit part configured to allow the wire to pass therethrough and extending to the operation mechanism along the wire; and an adjustment socket having a first end portion into which the fixing socket is inserted and a second end portion into which the conduit part is inserted, and screw-connected to an outer circumferential surface of the fixing socket and to an outer circumferential surface of the conduit part.

7 . The device of claim 6 , wherein a connection socket inserted into the second end portion of the adjustment socket is provided at a first end of the conduit part, and the connection socket and the adjustment socket are screw-connected to each other.

8 . The device of claim 6 , wherein:
screw threads are formed on the outer circumferential surface of the fixing socket and on the outer circumferential surface of the conduit part, respectively; screw threads corresponding to the screw threads of the fixing socket and the conduit part are formed on an inner circumferential surface of the adjustment socket; and the screw threads of the fixing socket and the conduit part extend in opposite directions.

9 . A vehicle comprising:
a vehicle body; a vehicle hood connected to the vehicle body; a latch device; an operation lever; a wire having a first side connected to the latch device and a second side connected to the operation lever, wherein when the wire is moved in a first direction by operation of the operation lever, the latch device is configured to be operated in conjunction with the operation lever; an elastic part being elastically compressible and having a first end portion connected to the wire; and a clearance elimination mechanism fixed to the vehicle body, wherein the elastic part is embedded in the clearance elimination mechanism and a second end portion of the elastic part is connected to and supported by the clearance elimination mechanism, and wherein the wire passes through the clearance elimination mechanism, such that the wire is configured to receive an elastic force provided in the first direction toward the operation lever by the elastic part to eliminate a clearance between the latch device and the wire when the clearance is generated.

10 . The vehicle of claim 9 , wherein the clearance elimination mechanism includes a fixing socket mounted on and fixed to the vehicle body, having a hollow region to allow the wire to pass therethrough, and having a seating space for the elastic part to be seated therein such that the second end portion of the elastic part is supported by a first end of the seating space. ii. The vehicle of claim 10 , wherein the wire has a hook portion bent to hook the first end portion of the elastic part and the fixing socket has a connection portion bent to hook the second end portion of the elastic part at the first end of the seating space to connect the wire to the fixing socket via the elastic part.

12 . The vehicle of claim 10 , wherein the seating space in the fixing socket is formed to extend longer than a length of the elastic part when tensioned.

13 . The vehicle of claim 10 , wherein the clearance elimination mechanism further includes a length adjustment socket mounted to be movable on the fixing socket in a length direction, while allowing the wire to pass therethrough, to adjust the clearance between the latch device and the wire according to a position to which the length adjustment socket moves.

14 . The vehicle of claim 13 , wherein the length adjustment socket includes:
a conduit part configured to allow the wire to pass therethrough and extending to the operation lever along the wire; and an adjustment socket having a first end portion into which the fixing socket is inserted and a second end portion into which the conduit part is inserted, and screw-connected to an outer circumferential surface of the fixing socket and to an outer circumferential surface of the conduit part.

15 . The vehicle of claim 14 , wherein a connection socket inserted into the second end portion of the adjustment socket is provided at a first end of the conduit part, and the connection socket and the adjustment socket are screw-connected to each other.

16 . The vehicle of claim 14 , wherein:
screw threads are formed on the outer circumferential surface of the fixing socket and on the outer circumferential surface of the conduit part, respectively; screw threads corresponding to the screw threads of the fixing socket and the conduit part are formed on an inner circumferential surface of the adjustment socket; and the screw threads of the fixing socket and the conduit part extend in opposite directions.
