Description

Folding type assistance handle for an automobile

The present invention relates to an auxiliary steering wheel of a vehicle, and more particularly, an auxiliary handle used in combination with a steering wheel of a vehicle to adjust the position in the vertical and horizontal directions with respect to the steering wheel as needed, so that the vehicle can be conveniently used. To a collapsible auxiliary handle.

Conventionally, a spherical auxiliary handle is coupled to a steering wheel of a vehicle so that a driver adjusts the steering angle of the vehicle using only the auxiliary handle as needed.

As described above, the conventional auxiliary handle used in combination with the steering wheel enables the driver to easily and smoothly perform the steering operation with one hand, and thus many drivers prefer to use the steering wheel as described above.

However, such a conventional auxiliary handle is fixed vertically with respect to the steering wheel, so that the auxiliary steering wheel standing vertically from the steering wheel when only the steering wheel is used, for example when driving on a highway, is used. Interfering with the driver's hand is inconvenient to use, and even if it is necessary to adjust the use position, the position can not be adjusted, there is a problem such as to interfere with safe driving.

In order to solve this problem, the steering wheel operation assistance device of the vehicle has been described in Korea Utility Model Publication No. 20-0184825 (2000.3.27).

1 and 2 showing a folding auxiliary handle of a vehicle described in Korean Utility Model Registration No. 20-0184825, FIG. 1 shows a perspective view of a use mode and FIG. 2 shows a perspective view of a non-use mode. In order to switch from the use mode shown in FIG. 1 to the non-use mode shown in FIG. The lower portion of the groove, that is, a plurality of grooves 5 are formed and the sleeve 4 is pushed back into the groove of the handle 3 against the force of the compression spring inside the handle body, the upright handle 3 ) Is bent about 90 ° in the radial direction of the circular handle 3 of the auxiliary handle 1 to convert the handle 3 from an upright state to a horizontal state.

In order to return from the non-use mode shown in FIG. 2 to the use mode shown in FIG. 1, simply grasping the handle 3 and turning it in the upright direction of the handle 3 causes the sleeve 4 to be removed from the compression spring. It is pushed out spontaneously by elasticity and is arranged to surround the first shaft portion 6 and the second shaft portion 7.

Foldable auxiliary handle of the registered Utility Model Publication No. 20-0184825 operating as described above was able to solve the inconvenience of driving due to the auxiliary handle which is fixed in the upright direction when the driver is driven by being configured so that the handle can be bent. .

However, the folding auxiliary handle described in Korean Utility Model Publication No. 20-0184825 catches the sleeve 4 having the plurality of grooves 5 formed at the bottom thereof, and then raises the sleeve 4 upward and then the handle 3. In this case, such an operation is not easy to be performed by one hand, and the user's gaze is temporarily turned off for a predetermined time to find the groove 5 of the sleeve 4 located at the lower side of the auxiliary handle during operation. There is a fatal problem that can cause an accident because it must be directed towards the auxiliary handle.

In order to solve the above problems, the present invention provides a folding auxiliary handle of a vehicle that allows the auxiliary handles to be easily positioned in the vertical and horizontal directions with a simpler operation and without being obstructed during driving. It aims to do it.

In order to achieve the above object, the knob of the auxiliary handle according to the present invention is installed on the upper end of the resilient means is installed in the resilient means is installed locking means locked to the pivot shaft when the pressing means is released And be configured to be bent in the horizontal direction.
