CONSTITUTION:A planar stopper member 11 having outer diameter l2 larger than that l1 of the head portion 6a of fixing screw 6 and to be inserted into the drum portion 6b of fixing screw 6 is provided between the projected portion of core members 2 projected from the opposite ends of grip body 1 and the head portion 6a of fixing screw 6 to be fixed to the chassis 7. While a collar member 10 is provided between the projected portion 3 and the base member 8 to mount the stopper member 11 on an annular projection 15 formed on the collar member 10 to be inserted into the drum portion 6b of fixing screw 6 thus to move the core member 2 in longitudinal direction in the gap l.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to retractable assist grits in which the grip body can be withdrawn or retracted.

In recent years, if the grip body remains extended inside the vehicle, it becomes a hindrance when getting on and off the vehicle.
A retractable assist grip has been proposed in which the grip body is stored in the vehicle body during normal times and can be pulled out from the vehicle body only when in use.

In other words, with conventional retractable assist grips,
As shown in FIG. As shown in Figures 2 and 3, a long hole 5 is bored in the longitudinal direction of the core material 2 at the bent portion 4, and a mounting screw 6'/ is inserted into the long hole 5. It is attached to the vehicle body 7 side via the pace member 8 which is inserted through f and fixed to the vehicle body 7 side, and when stored,
As shown in FIG. 2, the grip main body l is pushed into the vehicle body 7 side, and between the annular washer 9 placed under the head 6a of the mounting screw 60 and the collar member 10 inserted and fixed to the vehicle body 7 side. While guiding the protruding part 3 of the core material 2 inserted in the Plfit by the mounting screw 6 inserted into the elongated hole 5, the longitudinal bent part 4 of the core material 2 is engaged. Grip body 1f: Stored and held on the vehicle body 7 side, but when in use, contrary to the above case, the grip body 1f is pulled out from the vehicle body 7 as shown in Fig. The portion 3 is moved inward in the longitudinal direction of the core member 2 while being guided by the mounting screw 6, and the upper surface of the protruding portion 3 is brought into elastic contact with four locations a, b, c, and d on the outer periphery of the washer 9. At the same time, the grip main body 1 is pulled out from the vehicle body 7 and held by bringing the lower surface of the bent portion 4 into elastic contact with the upper surface of the oak portion *410.

By the way, in such a conventional retractable assist grip, when the grip main body 1 is pulled out, as shown in FIG. 5, the lower surface of the bent portion 4 formed on the protruding portion 3 is brought into elastic surface contact with the upper surface of the collar member 10, as shown in FIG. The grip main body 1 is maintained in the drawn-out state by the engagement friction force generated by the engagement friction points a, b, c, and d and one engagement friction surface e. Therefore, if there is a crack or the like on the outer periphery of the elongated hole 5, or if the drilling position of the elongated hole 5 is misaligned with respect to the mounting screw 6, there will be variations in the retaining friction force when pulling out. In addition, there is a drawback that the drawer cannot be operated clearly.

In view of such conventional problems, the present invention provides a structure in which a body of the mounting screw is provided between the protrusion of the core material protruding from both ends of the grip body and the head of the mounting screw for attaching the protrusion to the vehicle body. A plate-shaped stopper member with an outer diameter larger than the head outer diameter of the collecting U screw, through which the
When pulling out the narrow lip main body, the upper surface of the protrusion on the grill run main body side is brought into elastic surface contact with the edge of the front Hr2 stopper part 4A on the grip main body side, so that it can be easily pulled out with a light pulling operation. To provide a retractable assist grip which allows a grip body to be pulled out and which can reliably maintain the drawn-out state of the lip body for a long period of time after being pulled out.

Embodiments of the present invention will be described below based on the drawings. Incidentally, the same reference numerals are given to the same constituent parts as in the conventional example, and the explanation that "01" is repeated will be omitted.

FIG. 4 is a sectional view of a main part showing one embodiment of the retractable assist grip according to the present invention, and the fifth reason is an exploded perspective view showing borrowed members of the assist grip.

As shown in FIG. 4, there is a gap between the protrusion 3 of the core material 2 that protrudes from both ends of the grip body 10 and the head 6a of the screw 6 that extends the protrusion 3 toward the vehicle body 7. A plate-shaped stopper member 11 having an outer diameter 12 larger than the outer diameter t1 of the head 6a of the mounting screw 6 is inserted through the brush portion 6bK of the mounting screw 6 ( (See FIG. 5), and a metal collar member 10 is interposed between the protrusion 3 of the core member 2 and the base member 8 fixed to the vehicle body 7 side. This collar member; the extended insertion part 13 is inserted into the insertion hole 1 provided on the vehicle body 7 side.
4, the base member 8 is positioned and fixed to the vehicle body 7.

Further, the stopper member 11 is placed on the upper edge of the annular protrusion 15 formed on the collar member 1o, through which the body 6b of the mounting screw 6 is inserted. A gap t is formed between the force 2 member 10 and the stopper member 11 by the annular protrusion 15, and the auger 2 can move in this gap in the longitudinal direction. A reinforcing metal fitting 16 having an annular protrusion 16 a fitted into the screw insertion hole 8 a of the base member 8 is arranged at the lower part of the collar member 10 .

A cap 17 is attached to the base member 8 at t to cover the stopper member 11, several screws 6, etc.

Next, in the retractable assist grip according to the present invention having the above-described configuration, the grip main body 1'' is removed from the vehicle body 7.
When the IC is pulled out, the protrusion 3 of the core I2 is moved inward in the longitudinal direction of the core 2 while being guided by the mounting screw 6. Then, the protrusion 3
The lower surface of the bent portion 4 formed in the above is elastically brought into surface contact, and the upper surface of the protrusion 1Jj portion 3 on the grip body 1 side is elastically brought into surface contact with the edge of the stopper member 11 on the grip body 1 side. Therefore, the retaining friction surfaces f and e at these two locations
The retaining friction force ensures that the grip body is held in its pulled out state. During this pull-out operation, the free end 3a side of the protrusion 3 does not come into elastic contact with the edge of the stopper member 11 on the side opposite to the grip body 1, so that the grip body 1 can be pulled out with a light pull-out operation. can.

In addition, in this embodiment, upward folded portions 11a and lla are formed on both ends of the stopper member 11, and the curved surfaces of the folded portions 11a and I1m are securely brought into surface contact with the upper surface of the protruding portion 3 of the 8th section 2. However, the stopper portions 4 and 11 may be simply formed into a four-fold shape without forming such upward folded portions 11a and lla.

However, in this embodiment, the internal dimension l) of the elongated hole 5 on the side opposite to the grip body l is formed to be slightly smaller than the outer diameter dimension A11 of the annular protrusion 15 formed in the collar portion 4'AlO. Therefore, when the grip book f, 1 is pulled out, the annular protrusion 15 and the elongated hole 5 are frictionally engaged with each other.
The grip main body 1 can be held even more firmly at the fully drawn out position.

As is clear from the above description, the present invention protrudes from both ends of the grip body. 1-14J push-out jtb and the protrusion toward the vehicle body A plate-shaped stopper member with a large outside diameter is interposed, and when the grip body is pulled out, only the upper surface of the protruding portion on the grip body side is placed against the edge of the stopper member on the grip body side. Since surface contact is made elastic, the grip body can be pulled out with a light pull-out operation, and after being pulled out, the grip body can be reliably maintained in the drawn-out state for a long period of time.
