Description
AUXILIARY HANDLE OF _ STEERING WHEEL
BACKGROUND OF THE INVENTION
The present invention relates to a steering wheel auxiliary device, and more specifically to an auxiliary handle adapted for fastening to a steering wheel for permitting the driver to manipulate the steering wheel through the auxiliary handle.
Attaching an auxiliary handle to a steering wheel for turning by hand with less effort, has become popular. Figure 1 shows an auxiliary handle installed in a steering wheel according to the prior art. This auxiliary handle is comprised of two arched clamping plates hinged together and adapted for fastening to a steering wheel, a screw member threaded into respective screw holes in the arched clamping plates to fix them together, and a rounded handle mounted around the screw member. This structure of auxiliary handle has drawbacks. One drawback of this structure of auxiliary handle is that the friction force resulted between the inside wall of the rounded handle tends and the periphery of the screw member handle may causes the rounded handle to be -2- 21941 t ~
stuck. When the rounded handle is stuck, the driver will be unable to control the steering wheel through the auxiliary handle smoothly.
Furthermore, when a sudden force is applied to the steering wheel through the auxiliary handle, the arched clamping plates may be turned relative to the steering wheel, causing the steering wheel to be escaped from the control of the driver, and the covering leather of the steering wheel to be damaged.
SUMMARY OF THE INVENTION
It is one object of the present invention to provide an auxiliary handle which eliminates the aforesaid problems and, which can be easily installed in a steering wheel for a positive steering control. It is another object of the present invention to provide an auxiliary handle which uses a bearing-like rotary member to support the hand grip, permitting the hand grip to be smoothly turned to positively control the steering wheel. According to still another object of the present invention, the mounting device of the auxiliary handle is internally mounted with a rubber cushion, so that the mounting device can be 2i941 1 1 firmly secured to the steering wheel, and does nct damage the leather covering of the steering wheel when turned. According to still another aspect of the present invention, the auxiliary handle can be made having a single color or multiple colors, or a decorative design. According to still another aspect of the present invention, the auxiliary handle is ergonomically engineered, having a plurality of finger recesses for the griping of the fingers.

The top cap 14 is mounted within the top recess 12 of the hand grip 11, having a female screw 141 fitted into the center through hole 13 of the hand grip 11 and secured thereto by a screw 15. The collar 18 is mounted around the periphery groove 17 of the hand grip 11. The rotary member 2 is a metal bearing mounted within the bottom chamber 16 of the hand grip 11, having a core 22 and a screw hole 21 at the center of the core 22. The bottom cap 3 comprises a center hole 31, two mounting holes 32 at two opposite lateral sides respectively fastened to the bottom screw holes 161 of the hand grip 11 by a respective screw 33. The mounting device 4 comprises a mounting unit 43, which is comprised of a plurality of plates 42 hinged together, a fastening screw unit 44 mounted on the mounting unit 43 and moved between a first position to close the mounting unit 43 (see Figure 4A) and a second position to open the mounting unit 43 (see Figure 4B), a coupling rod 41 raised from the periphery of one plate 42 of the mounting unit 43 and defining an axial through hole 411 through the corresponding plate 42 of the mounting unit 43. The coupling rod 41 is inserted through the center hole 31 of the bottom cap 3, and connected to the screw hole 21 of the core 22 of the rotary member 2 by a screw 45.
Further, a rubber cushion 46 is mounted around the inside wall of the mounting unit 43.
Referring to Figures 4A and 4B, when in use, the fastening screw unit 44 is moved to the second position to open the mounting unit 43, permitting the mounting unit 43 to be mounted on the steering wheel 5, and then the fastening screw unit 44 is moved to the first position to close the mounting unit 43, causing the mounting unit 43 to be fixed to the steering wheel 5. Because the rubber cushion 46 is mounted around the inside wall of the mounting unit 43, the installation of the auxiliary handle does not damage the covering of the steering wheel 5 when the steering wheel 5 is turned. Furthermore, the rubber cushion 46 enables the auxiliary handle to be firmly fixed to the steering wheel 5.
Referring to Figure 5, when the auxiliary handle is fastened to the steering wheel 5, the user can turn the steering wheel through the auxiliary handle.
Referring to Figure 6, the hand grip 11 may be ergonomically engineered, having a plurality of finger recesses 11' spaced around the border.
Through the finger recesses 11', the hand grip 11 21 941 ~ 1 can be positively seized with the hand.
Furthermore, the hand grip 11 of the handle 1 can have a single color or multiple colors, or be decorated with a design.

The hand grip 11 comprises a top recess 12, a bottom chamber 16 adapted for receiving the rotary member 2, a center through hole 13 disposed in communication between the top recess 12 and the bottom chamber 16, two bottom screw holes 161 at two opposite sides of the bottom chamber 16, and a periphery groove 17. The top cap 14 is mounted within the top recess 12 of the hand grip 11, having a female screw 141 fitted into the center through hole 13 of the hand grip 11 and secured thereto by a screw 15. The collar 18 is mounted around the periphery groove 17 of the hand grip 11. The rotary member 2 is a metal bearing mounted within the bottom chamber 16 of the hand grip 11, having a core 22 and a screw hole 21 at the center of the core 22. The bottom cap 3 comprises a center hole 31, two mounting holes 32 at two opposite lateral sides respectively fastened to the bottom screw holes 161 of the hand grip 11 by a respective screw 33. The mounting device 4 comprises a mounting unit 43, which is comprised of a plurality of plates 42 hinged together, a fastening screw unit 44 mounted on the mounting unit 43 and moved between a first position to close the mounting unit 43 (see Figure 4A) and a second position to open the mounting unit 43 (see Figure 4B), a coupling rod 41 raised from the periphery of one plate 42 of the mounting unit 43 and defining an axial through hole 411 through the corresponding plate 42 of the mounting unit 43. The coupling rod 41 is inserted through the center hole 31 of the bottom cap 3, and connected to the screw hole 21 of the core 22 of the rotary member 2 by a screw 45.
Further, a rubber cushion 46 is mounted around the inside wall of the mounting unit 43.
Referring to Figures 4A and 4B, when in use, the fastening screw unit 44 is moved to the second position to open the mounting unit 43, permitting the mounting unit 43 to be mounted on the steering wheel 5, and then the fastening screw unit 44 is moved to the first position to close the mounting unit 43, causing the mounting unit 43 to be fixed to the steering wheel 5. Because the rubber cushion 46 is mounted around the inside wall of the mounting unit 43, the installation of the auxiliary handle does not damage the covering of the steering wheel 5 when the steering wheel 5 is turned. Furthermore, the rubber cushion 46 enables the auxiliary handle to be firmly fixed to the steering wheel 5.
Referring to Figure 5, when the auxiliary handle is fastened to the steering wheel 5, the user can turn the steering wheel through the auxiliary handle.
Referring to Figure 6, the hand grip 11 may be ergonomically engineered, having a plurality of finger recesses 11' spaced around the border.
Through the finger recesses 11', the hand grip 11 21 941 ~ 1 can be positively seized with the hand.
Furthermore, the hand grip 11 of the handle 1 can have a single color or multiple colors, or be decorated with a design.
