[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door handle seat mounting structure in which a door handle seat can be firmly mounted with one touch.

[0002]

2. Description of the Related Art A door handle seat is generally attached to a base of an attachment side of a door handle so as to improve the appearance and defense ability of the door handle. For example, in Japanese Utility Model Application No. 3-79770, which has already been proposed by the applicant, a lock plate to be attached to a door and a door handle seat for accommodating the plate inside are provided. A mating piece is formed, and an engagement groove and a screw hole are provided on the upper and lower end inner surfaces of the door handle seat, and when attaching the door handle seat, after attaching the lock plate to the door,
This has been done by inserting the engagement groove into the locking claw and screwing a set screw into the screw hole from outside the door handle seat so that the screw shaft end is engaged with the engagement piece.

[0003]

However, in the case of this structure, mounting the door handle seat requires screw fixing work, which is troublesome, and the number of parts increases, and the structure of the door handle seat becomes complicated. And so on. The present invention solves such a problem, and when installing the door handle seat, it can be easily and quickly performed with one touch without the need for screwing work, while reducing the number of parts and strengthening the mounting strength , Moreover, the appearance of mounting has been improved
And has an object to provide a mounting structure of the door handle seat.

[0004]

The mounting structure of the door handle seat configured as described above does not use the conventional screw fixing means when mounting the door handle seats 11 and 12 disposed inside the door 3 as described later. Processing of screws and screw holes for this purpose becomes unnecessary.

On the other hand, the door handle seats 11, 12 require machining of the engaging grooves 15, 16 and the concave groove 17, and these are formed by machining the inner surfaces of the flanges 11a, 12a to form a V-shaped section. Forming a mating groove 15 and attaching it to the inside of the door 3;
A groove 17 is formed in the end surface of the flange 11a of the door handle seat 11. In this case, the engagement grooves 15 and 16 and the concave groove 17 may be formed integrally with the door handle seats 11 and 12 so as to save labor for processing.

Next, when assembling the door handle seats 11 and 12, the lock 7 is first accommodated in the side hole 4 formed in the door 3 and fixed with screws 40 via the front plate 8.

Before and after this, the shaft of the door handle 10 is inserted into the through hole 14 and the through hole 21 of the door handle seat 12 and the fixed seat 19, which are attached to the outside of the door 3, and the shaft end of the door handle is inserted. A suitable retaining means is provided between the door handle 9 and the fixed seat 19, while the door handle seat 11 and the through hole 13 and the through hole 20 of the fixed seat 18 attached to the inside of the door 3 are provided with the door handle 9. The shaft is inserted, and a suitable stopper is provided between the shaft end and the fixed seat 18.

[0019] Then, the insertion of the shaft end portion of the door handle 9 in the square hole 3 6 padlock 7, the door handle seat 19 integral with Nejipaipu 34, from the outside of the door 3 into the through-holes 6, 6 Insert.

On the other hand, the fixing seat 18 is applied from the inside of the door 3, the screw holes 33, 33 are aligned with the through holes 6, 6, and the screws 32, 32 are screwed through the through holes 6, 6 to the screw pipes 34, 34. And tighten it.

After the fixing seats 18 and 19 are fixed to the inner and outer surfaces of the door 3 in this manner, the door handle seats 11 and 1 are fixed to these.
Press 2.

For example, when the groove 17 is positioned on the lower side and the door handle seat 11 is pushed into the fixed seat 18, the flange portion 11 a
Is engaged with the flange portion 18a of the fixed seat 18, and at the end of the pushing, the inner surface rides on the convex portion 28 protruding from the holding piece 24, and pushes the holding piece 24 inward against its elasticity. .

Then, when the inner surface of the door handle seat 11 comes into contact with the outer surface of the fixed seat 18 and is slightly further pushed in thereafter, the projection 28 engages with the engagement groove 15 and the projection 28 engages with the holding piece 24. The engagement grooves 15 are pressed against each other via the elasticity accumulated in the grooves.

In this case, since the projection 28 is placed in point contact with the engaging groove 15, the contact surface pressure between them becomes larger than that of the engaging groove 15 formed in a curved surface. The door handle seat 11 is firmly attached to the fixed seat 18. Therefore, the door handle seat 11 does not rotate along the engagement groove 15 or the door handle seat 11 does not drop off from the fixed seat 18 due to an impact at the time of closing the door.

Further , the door handle seat 11 is pushed in.
Sometimes, the holding piece 24 is narrower than the partition piece 41,
The pressing and bending is promoted, and the engagement between the projection 28 and the engagement groove 15 is improved.
It is done easily and quickly. Moreover, the projection 28 is a holding piece.
24, the holding piece 24
Of the door handle seat 11 compared to the one provided at the tip of
Pushing force is reduced. Thus, the holding piece 24 is pushed and bent.
The engagement groove 15 is engaged with the projection 28, and the door
The peripheral end of the handle 11 engages with the peripheral surface of the door 3, while
The holding piece 24 is slightly shorter than the partitioning piece 41,
8 and the engaging groove 15 are displaced by the minute amount e.
A handle seat 11 is equivalent to minute amount e with respect to fixed seat 18,
It is attached to the door 3 by urging it,
The appearance around the door 3 is improved because it is prevented or suppressed.
Is done.

As described above, according to the present invention, the door handle seat 11 is provided.
Can be mounted with a single touch, so that this can be performed easily and quickly, without the need for complicated screwing work as in the past. The method of mounting the door handle seat 12 and its operation and effect are substantially the same as those of the door handle seat 11.

The door handle seats 11 and 12 assembled as described above are connected to the door handles 9 and 10 as shown in FIG.
Since the mounting means such as screws are wiped out from their front appearance, the appearance is good and the aesthetic appearance of the inner and outer surfaces of the door 3 is improved.

Further, since there is no fixing screw on the peripheral surface of the door handle seat 11 attached to the inside of the door 3, the appearance is better and the protection ability is improved as compared with the conventional type. Further, since the concave groove 17 is located at the lower end of the door handle seat 11 and is away from the normal field of view, the appearance is not impaired.

When the door handle seat 11 is to be removed, a tool such as a screwdriver is inserted into the concave groove 17, the tip of which is engaged with the door 3, and the opening edge is squeezed to the fulcrum.
Can be removed.

[0030]

[Effect of the Invention] As described above, the mounting structure of the door handle seat of the present invention is formed by forming a notch groove in the flange of the fixed seat in the axial direction.
The holding piece and the partition piece are alternately partitioned in the circumferential direction of the flange.
Elastically displaceable along the axial direction on the holding piece and the partition piece.
The door handle seat to the fixed seat with one touch
Simple and quick installation. Also, the holding piece
Because it was formed narrower than the adjacent partition piece, the door handle
When mounting the seat, the pushing and bending of the holding piece is enhanced, and
Since a substantially hemispherical projection is provided at the approximate center of the holding piece,
The push-in force of the handle is reduced, and the door
The attachment of the seat can be easily performed. Furthermore,
The tip of the holding piece is slightly shorter than the tip of the adjacent partition
The door handle seat is formed when the projection and the engagement groove are engaged.
Since the door was urged toward the door, the periphery of the door handle seat and the door
A gap between the door and the door can be prevented, and the appearance of the door peripheral surface can be improved.
