Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a knob mounting structure for a regulator handle used for opening and closing an automobile window glass, etc.

(Prior Art) Conventionally, as a knob mounting structure of this type of regulator handle, there is one shown in FIG. 7 or FIG. 9.

The one shown in FIG. 7 has a stepped portion 23 formed on the inner surface of a bearing portion 22 provided on a knob 21, and a lever 24 rotatably supported at one end, as shown in FIG.
The shaft portion 26 is approximately half-ring shaped and has a locking pawl 25 at the tip, and the shaft portion 26 of the knob 21 is attached to the bearing portion 2 of the knob 21.
A shaft portion 26 of a lever 24 is fitted into the lever 2, and the elasticity of the shaft portion 26 causes the locking pawl 25 to lock onto the stepped portion 23. When the knob 21 is held and turned, the other end (not shown) of the lever 24 is rotated, and the window is raised and lowered.

FIG. 9 shows a lever 27 with a bearing portion 29 having a stepped portion 28 on the inner surface, contrary to that shown in FIG. 7.
On the other hand, the tip of the shaft portion 31 of the knob 30 is divided into four parts to maintain elasticity, and a locking pawl 32 that locks with the step portion 28 is formed.

(Problems to be Solved by the Invention) However, in any of the above regulator handles, if an excessive tensile force is applied to the knobs 21, 30, the knobs 21, 30 may come off, or
Wear of the locking claws 25 and 32 due to repeated and long-term use;
Alternatively, the locking relationship between the stepped portions 23, 28 and the locking claws 25, 32 could not be maintained due to plastic deflection of the shaft portions 26, 31 having elasticity.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a knob mounting structure for a regulator handle that can reliably prevent the knob from coming off.

(Means for solving the problem) In order to solve the above problem, the present invention forms a cylindrical shaft part at one end of a rotatably provided lever,
In the knob mounting structure of the regulator handle in which the knob is externally fitted onto the shaft, a stepped portion is formed in the inner circumferential direction of the shaft, and at least two elastic legs are provided on the inner surface of the bottom of the knob. established a department,
A locking pawl that locks onto the stepped portion of the shaft is formed at the tip of the leg, and further engages between at least any two of the legs to restrain inward deflection of the leg. A bendable lock bar is integrally formed on either leg.

(Example) Next, an example of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 3, the knob 1 has four elastic legs 3a, 3b, 3c, and 3d arranged equally on the same circumference on the inner surface of the bottom of the base 2. Each leg 3a, 3b, 3c, 3d
A locking pawl 4 is formed at the tip. Furthermore, a cross-shaped lock bar 6 having an engaging portion 5 at the tip is bendably provided integrally at the tip of the locking pawl 4 of the leg portion 3a. The tip of the leg portion 3b facing the leg portion 3a is divided into two parts to form an engaging claw 7 facing the lock bar 6 of the leg portion 3a.
The engaging portion 5 of is capable of engagement. Furthermore, when the lock bar 6 is bent, the shoulders and both ends of the engaging portion 5 of the lock bar 6 are connected to the legs 3b, 3c, and 3.
d, respectively.

The lever 8 is rotatably attached to the door of the automobile, and as shown in FIG. It is being The inner surface of the shaft portion 9 has a stepped portion 10 on which the locking claw 4 of the knob 1 is locked.
A locking protrusion 11 is formed in the circumferential direction.

In the regulator handle consisting of the knob 1 and the lever 8 as described above, in order to attach the knob 1 to the lever 8, first, the legs 3a, 3b of the knob 1,
3c and 3d fit into the inner surface of the shaft portion 9 of the lever 8,
In addition, the knob 1 is fitted onto the shaft portion 9 such that the inner surface of the base portion 2 fits onto the outer surface of the shaft portion 9. At this time, the locking claws 4 of the legs 3a, 3b, 3c, 3d come into contact with the locking protrusions 11 on the inner surface of the shaft 9, but if the knob 1 is pushed strongly, the legs 3a, 3b, 3c, 3d is bent inward due to its elasticity, and as shown in FIG.

Then, as shown in FIG. 5, when the lock bar 6 of the leg portion 3a is bent and the engaging portion 5 is pushed between the engaging claws 7 of the leg portion 3b, the engaging claws of the engaging portion 5 7
is engaged. At this time, as shown in FIG. 6, the shoulder portion 12 of the engaging portion 5 comes into contact with the leg portion 3b, and the ends 13 and 14 on both sides of the lock bar 6 come into contact with the legs 3c and 3d, respectively. Therefore, leg 3
a, 3b, 3c, and 3d are each restrained from inward deflection by the lock bar 6, so that the engagement relationship between each locking pawl 4 and the stepped portion 10 of the shaft portion 9 is reliably maintained. .

Next, when you hold the knob 1 and turn the lever 8, the inner surface of the base 2 of the knob 1 slides against the outer surface of the shaft 9 and acts as a bearing, so the operation of the knob 1 is extremely smooth and there is no wobbling. do not have.

(Effects of the invention) As is clear from the above description, according to the invention, the knob is externally fitted onto the cylindrical shaft formed at one end of the lever of the regulator handle, and the knob is fitted onto the inner surface of the bottom of the knob. After locking the locking claws at the tips of at least two vertically arranged legs to the stepped portion formed on the inner surface of the shaft, a lock bar provided integrally with one of the legs so as to be bendable The inward bending of each leg is restrained.

Therefore, the knob does not require any special member to prevent it from coming off, so it can be reliably prevented from coming off without increasing the number of parts. Further, even if the knob becomes worn or damaged due to long-term use, the knob can be easily replaced by disengaging the lock bar.
