ABSTRACT:

The content of Application No.TOKUGANHEI
10-141577
, filed on May 22, 1998 in Japan is hereby incorporated by reference.
BACKGROUND OF THE INVENTION
The present invention relates to a car inside handle unit structure.
As an example of the related art, the car inside handle unit structure is set forth in Utility Model Application Publication (KOKOKU) Hei 6-7196.
SUMMARY OF THE INVENTION
In the car inside handle unit structure in the related art, to increase an overlapping length between a bearing hole of a handle and boss axes of a base is limited. Therefore, in order to enhance a handle supporting strength of a base, change of material is needed, for example, costly polycarbonate material, etc. must be utilized.
It is an object of the present invention to provide a car inside handle unit structure which is able to enhance the handle supporting strength without change of material.
In order to achieve the above object, a car inside handle unit structure of the present invention comprises a handle, a base, an energizing member, and a stopper. The handle has a coupling portion and an operating portion extended from the coupling portion. The coupling portion has a pair of opposing end walls each of which has a bearing hole and a groove. The groove extends from the bearing hole in a direction opposite to the operating portion to open the bearing hole. The base is fixed to a car body and has a base plate and a pair of supporting walls which project from the base plate to oppose to each other. The supporting walls have a pair of boss axes which project from the supporting walls to oppose to each other. The boss axes are inserted into the bearing holes respectively to support the handle rotatably from a releasing position to a latching position via an unlatching position. The operating portion is positioned in substantially parallel with the base plate in the latching position, and stands upright in the base plate in the unlatching position. Each of the boss axes has an outer peripheral surface consisting of a pair of flat surfaces positioned in parallel and circular arc surfaces formed between the flat surfaces. Both the circular arc surfaces come into contact with a partial inner peripheral surface between the latching position and the unlatching position. When the handle is positioned in the releasing position, only one of the circular arc surfaces comes into contact with the partial inner peripheral surface of the bearing hole and also the flat surfaces allows the boss axis to pass through the groove. The boss axis is inserted/pulled out into/from the bearing hole through the groove. The flat surfaces being tilted from a vertical direction of the base plate to a side which is opposite to an extending direction of the operating portion positioned in the latching position. The energizing member is positioned to expand between the base and the handle, and energizes the handle toward the latching position. The stopper is fitted attachably/detachably to the base to prevent the handle from turning to the releasing position via the unlatching position.
According to the above configuration, since the flat surfaces of the boss axes are tilted from the vertical direction of the base plate to the side which is opposite to the extending direction of the operating portion positioned in the latching position, contact areas between circular arc surfaces of the boss axes in the unlatching position and the partial inner peripheral surface of the bearing hole can be increased. Therefore, when the handle is positioned in the unlatching position, a surface pressure applied to the boss axes of the base can be reduced and thus the handle can be supported firmly.
