Description

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

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

That is, in the conventional retractable assist grip, as shown in FIG.
The protruding part 3 is bent so that the side surface shape is approximately V-shaped, and a long hole is formed in the longitudinal direction of the core material 2 at the bent part 4 as shown in FIGS. 2 and 3. 5 is drilled, and a mounting screw 6 is inserted into this elongated hole 5 to attach it to the vehicle body 7 side via a base member 8 fixed to the vehicle body 7 side. , when the grip body 1 is pushed into the vehicle body 7 side, there is a gap between the annular washer 9 placed under the head 6a of the mounting screw 6 and the collar member 10 inserted and fixed to the vehicle body 7 side! The protruding part 3 of the core material 2 inserted therein is guided by the mounting screw 6 inserted into the elongated hole 5, and moved outward in the longitudinal direction of the core material 2 to remove the outer circumference of the washer 9. By engaging the bent portion 4 with the
Knob body l-￥r: While stored and held on the main body 7 side, when in use, contrary to the above case, as shown in Fig. 1,
Pull out the grip body 1 from the vehicle body 7 and remove the protrusion 3.
While being guided by the mounting screws 6, the core material 2 is moved inward in the longitudinal direction, and four locations a on the outer circumference of the washer 9,
By bringing the top surface of the protruding portion 3 into elastic contact with b, c, and a, and by bringing the bottom surface of the bent portion 4 into elastic contact with the top surface of the collar member 0, the Grip main body 1 is pulled out from the vehicle body 7 and held. That's what I do.

By the way, in such a conventional retractable bruise/strike grip, when the grip body 1 is pulled out, as shown in FIG. While bringing the outer peripheral edge of the elongated hole 5 into elastic contact, as shown in FIG. The grip main body 1 is maintained in the drawn-out state by the holding frictional force generated by the engagement points a, b, c, and d at these four locations and the engagement friction surface e at one location. Therefore, there may be a hole on the outside of the elongated hole 5, or the four installation positions of the elongated hole 5 relative to the mounting screw 6 may be -f or τ^, and the retention during pulling out may occur. This has the disadvantage that the frictional force varies and the drawer cannot be operated smoothly.

In view of such conventional problems, the present invention provides a structure in which a body of the mounting screw is provided between the protruding part of the core material protruding from both sides of the grip body and the head of the mounting screw for attaching the protruding part to the handle body side. A plate-shaped stopper member having an outer diameter larger than the head outer diameter of the mounting screw is interposed between the protrusion of the core member and the base member. , a collar member having a protrusion protruding in the direction of the free edge of the protrusion is interposed; a top surface of the protrusion comes into elastic surface contact with both side edges of the stopper member when the grip main body is pulled out; Another object of the present invention is to provide a retractable assist grip in which the free end of the protrusion comes into elastic contact with the protrusion of the collar member, thereby reliably holding the grip main body in the drawn-out state for a long period of time. do.

Embodiments of the present invention will be described below based on the drawings. Components that are the same as those of the conventional example are given the same reference numerals, and redundant explanation thereof will be omitted.

FIG. 4 shows a retractable assist grip sofa according to the present invention.

FIG. 5 is an exploded perspective view showing the constituent members of the assist grip.

As shown in FIG. 4, there is a mounting screw 6 between the protrusion 3 of the grip body 10 that protrudes from both ends of the grip body 10 and the head 6a of the mounting screw 6 that attaches the protrusion 3 to the vehicle body 7. A plate-shaped stopper member 11 is inserted into the body 6b of the mounting screw 6 and has an outer diameter e larger than the outer diameter l of the head 6a of the mounting screw 6 (Fig. 5). reference). Further, a base member 8 fixed to the protruding portion 3 of the core material 2 and the vehicle body 7 side
A metal collar piece 10 having a protrusion 12 protruding toward the free end 3a of the protrusion 3 is interposed between the protrusion 3 and the protrusion 3. The insertion portion (3) extending from the protrusion 12 formed on the collar member 10 is inserted into the insertion hole 14 provided on the vehicle body 7 side. The cover 8 is positioned and fixed to the main body 7. The stopper member 11 is placed on the upper B edge of the annular protrusion 15, which is shaped like a groove, in the collar member 10, and through which the body 6b of the mounting screw 6 is inserted. This annular projection II! 15, a gap l is formed between the collar member [0 and the stopper member 11], and the core member 2 can move in the longitudinal direction within this gap l. A reinforcing metal fitting 16 having an annular protrusion L6a fitted into the screw insertion hole 8a 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 to cover the stopper member 11, the mounting screw 6, and the like.

Next, the operation of the retractable assist grip according to the present invention having the above configuration will be explained.

When storing the grip body without removing it, as shown in Fig. 4, push the grip body 1 into the car body 7 and remove the core material 2.
The protruding part 3 of the core member 2 is moved outward in the longitudinal direction of the core member 2 while being guided by the mounting screw 6, and both ends of the stopper partially controlled are brought into frictional engagement with the upper surface of the protruding part 3 of the core member 2. By frictionally engaging the lower surface of the bent portion 4 formed on the protruding portion 3 with the upper surface of the collar member 10, the grip main body 1 is housed and held on the vehicle body 7 side.

Next, when pulling out the grip body, as shown in FIG. 2 inward in the longitudinal direction. Then, both ends of the stopper member 11 and the upper surface of the protrusion 3 of the core member 2, and the lower surface of the bent portion 4 and the upper surface of the collar member 10 come into elastic surface contact, respectively, and the free end 3a of the protrusion 3 Since the lower surface also comes into elastic surface contact with the protrusion 12 formed on the collar member 10, the core member 2 and the collar portion u'to are firmly coupled by the frictional engagement therebetween. Therefore, the drawn-out state of the grip body 1 relative to the vehicle body 7 can be reliably maintained.

In this embodiment, upwardly turned folded parts ita and ha are formed on both ends of the stopper part U' 11, so that the curved surfaces of the folded parts tta and ita are securely attached to the upper surface of the protruding part 3 of the core material 2. Although pressure is applied so as to make surface contact, the stopper member 11 may be simply formed into a plate shape without forming such upward folded portions 11a and tla.

Further, in this embodiment, the protrusion 12 is formed by bending the side surface into a substantially inverted U-shape, but the present invention is not limited to this. For example, the protrusion may be formed by applying weld overlay to that portion. It's okay.

As is clear from the above description, the present invention provides a structure in which the body of the mounting screw is connected 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 having an outer diameter larger than the head outer diameter of the mounting screw is interposed between the protrusion of the core member and the base member, A collar member having a protrusion protruding toward the free end of the protrusion is interposed, and when the grip main body is pulled out, the upper surface of the protrusion comes into elastic surface contact with both end edges of the stopper member. Since the free end of the protrusion comes into elastic contact with the protrusion of the collar member, the grip main body can be reliably maintained in the drawn-out state for a long period of time. In addition, since the collar member is detachably attached to the base member, if the protrusion formed on it becomes worn, the worn collar member can be replaced with a new collar member as soon as possible. can be done,
This has the effect that the grip body can be reliably held in the drawn-out state at all times.
