Abstract

A structure for mounting a spare tire for antitheft may include a carrier support bracket on which a spare tire is mounted, a bracket mounted at a bottom surface of a vehicle and supporting the spare tire, and a carrier winding or unwinding a wire mounted at the carrier support bracket in order for the spare tire to be moved upwardly and downwardly, the carrier further including a carrier housing including a top surface formed with a through hole, and a bottom surface formed with a projecting hole, a shaft bolt rotatably mounted at the carrier housing and adapted to wind or unwind the wire by rotation thereof, and a socket to transmit a torque applied from an outside of the vehicle to the shaft bolt or to block the torque not to be transmitted to the shaft bolt.

First claim

What is claimed is:

1. A structure for mounting a spare tire for antitheft, including a carrier support bracket on which a spare tire is mounted, a bracket mounted at a bottom surface of a vehicle and supporting the spare tire, and a carrier winding or unwinding a wire mounted at the carrier support bracket in order for the spare tire to be moved upwardly and downwardly, the carrier further comprising:
a carrier housing including a top surface formed with a through hole, and a bottom surface formed with a projecting hole;
a shaft bolt rotatably mounted at the carrier housing and adapted to wind or unwind the wire by rotation thereof; and
a socket connected to the shaft bolt, the socket configured to transmit a torque applied from an outside of the vehicle to the shaft bolt and also configured to block the torque from being transmitted to the shaft bolt.

2. The structure for mounting the spare tire for antitheft of claim 1 , wherein the through hole and the projecting hole of the carrier housing are coaxially disposed, and
the shaft bolt penetrates the through hole and the projecting hole.

3. The structure for mounting the spare tire for antitheft of claim 1 , wherein a height of the projecting hole is equal to or greater than a height of the shaft bolt projecting from a lower portion of the carrier housing.

4. The structure for mounting the spare tire for antitheft of claim 1 , wherein the shaft bolt comprises:
a bolt portion rotatably mounted on the top surface of the carrier housing; and
a shaft portion formed to be downwardly projected from a bottom surface of the bolt portion.

5. The structure for mounting the spare tire for antitheft of claim 4 , wherein the shaft portion comprises a first engaging portion disposed at a lowest end portion of the shaft portion and formed with a multiple angular columnar shape for mounting the socket to the shaft bolt.

6. The structure for mounting the spare tire for antitheft of claim 5 , wherein the shaft portion comprises a torque transmitting portion disposed at an upper end portion of the first engaging portion and formed with a multiple angular columnar shape to which a torque applied to the socket from the outside of the vehicle is transmitted from the socket.

7. The structure for mounting the spare tire for antitheft of claim 6 , wherein the shaft portion comprises a second engaging portion disposed at an upper end portion of the torque transmitting portion, formed with an inclined cylindrical shape of which a diameter of a top surface thereof is greater than that of a bottom surface thereof and fixing the position of the socket so that the torque received from the socket is transmitted to the torque transmitting portion.

8. The structure for mounting the spare tire for antitheft of claim 7 , wherein the shaft portion comprises a torque blocking portion arranged at an upper end portion of the second engaging portion and formed with a cylindrical shape for blocking the torque transmitted from the socket not to be transmitted to the shaft portion.

9. The structure for mounting the spare tire for antitheft of claim 8 , wherein a minimum width of the first engaging portion passing through a central axis of the first engaging portion exceeds a minimum width of the torque transmitting portion passing through a central axis of the torque transmitting portion.

10. The structure for mounting the spare tire for antitheft of claim 8 , wherein the diameter of the top surface of the second engaging portion exceeds a minimum width of the torque transmitting portion passing through a central axis of the torque transmitting portion.

11. The structure for mounting the spare tire for antitheft of claim 8 , wherein a minimum width of the torque transmitting portion passing through a central axis of the torque transmitting portion exceeds a diameter of the torque blocking portion.

12. The structure for mounting the spare tire for antitheft of claim 1 , wherein the socket comprises a contacting portion to which a torque for rotating the socket is applied from the outside of the vehicle and formed with a multiple angular columnar shape.

13. The structure for mounting the spare tire for antitheft of claim 12 , wherein the socket comprises a transmitting portion arranged at a top surface of the contacting portion in order to transmit the torque applied to the contacting portion to the shaft bolt, and formed with a cylindrical shape.

14. The structure for mounting the spare tire for antitheft of claim 13 , wherein an inner space of a cylindrical shape is formed in the socket.

15. The structure for mounting the spare tire for antitheft of claim 14 , wherein the transmitting portion comprises a multiple angular hole formed at a top surface of the transmitting portion in order to communicate the inner space with an outside of the socket.

16. The structure for mounting the spare tire for antitheft of claim 15 , wherein a minimum width of the multiple angular hole passing through a central axis of the multiple angular hole exceeds a diameter of the torque blocking portion.

17. The structure for mounting the spare tire for antitheft of claim 15 , wherein a minimum width of the multiple angular hole passing through a central axis of the multiple angular hole is equal to or greater than a minimum width of the torque transmitting portion passing through a central axis of the torque transmitting portion.

18. The structure for mounting the spare tire for antitheft of claim 15 , wherein a minimum width of the multiple angular hole passing through a central axis of the multiple angular hole is less than a minimum width of the first engaging portion passing through a central axis of the first engaging portion.

19. The structure for mounting the spare tire for antitheft of claim 15 , wherein a minimum width of the multiple angular hole passing through a central axis of the multiple angular hole is less than a diameter of a top surface of the second engaging portion.

20. The structure for mounting a spare tire for antitheft of claim 15 , wherein a diameter of the inner space exceeds a maximum width of the first engaging portion and a diameter of a top surface of the second engaging portion.
