The door handle seats 11 and 12 are formed in a thick and flat bowl shape as shown in the figure, and through holes 13 and 14 into which a ring collar described later can be inserted are formed in the centers thereof.

The door handle seats 11 and 12 have flange portions 11a and 12a on their side peripheral surfaces, and engagement grooves 15 and 16 having a V-shaped cross section are formed on the inner surfaces of the flange portions 11a and 12a. The convex portions described later are fitted into the grooves 15 and 16. In the figure, reference numeral 17 is a recessed groove 17 formed in the lower end surface of the collar portion 11a, into which a tool or the like can be inserted from the outside.

Fixed seats 18 and 19 made of synthetic resin are attached to the inner and outer surfaces of the door 3, and these are formed in a flat bowl shape, and the shaft portions of the handles 9 and 10 are inserted in the centers thereof. Possible through holes 20 and 21 are formed. Cylindrical ring collars 22 and 23 project from the opening edges of the through holes 20 and 21 and are inserted into the through holes 13 and 14.

Collar portions 18a, 19a engageable with the inner surfaces of the collar portions 11a, 12a are provided on the side peripheral surfaces of the fixed seats 18, 19, and a plurality of holding pieces 24, 25 are provided on these peripheral surfaces. Has been formed. The holding pieces 24, 25 are defined by a pair of notched grooves 26, 27 in which the collar portions 18a, 19a are formed in the radial direction, and substantially hemispherical convex portions 28, 29 are provided on their outer end surfaces so as to project. .

The convex portions 28 and 29 are provided so as to be fitted into the engaging grooves 15 and 16, and at the time of fitting these, the respective central positions of the engaging grooves 15 and 16 and the convex portions 28 and 29 are shown in FIG. As described above, the door handle seats 11 and 12 are biased toward the door 3 side by being displaced by a small amount e. Further, the end faces of the holding pieces 24, 25 are formed smaller than the end faces of the collar portions 18a, 19a by a minute amount h, as shown in FIG. 6, so that the door handle seats 11, 12 can be mounted.

Bosses 30 and 31 are provided so as to face each other at inner end portions of the collar portions 18 a and 19 a, of which a boss hole 33 into which a screw 32 can be inserted is provided. A screw pipe 34 into which the screw 32 can be screwed is projectingly provided on 31.

In addition, reference numeral 35 in the drawing is a reinforcing rib projecting from the inner surface of the door handle seat 11, 12, 36 and 37 are square holes and screw holes provided on the side surface of the lock 7, and the square hole 36 is the door handle. The shaft ends 9 and 10 can be engaged with each other, and the screw hole 37 allows the screw 32 to be inserted. 38 is a latch bolt, 39 is a screw hole formed in the front end surface of the lock 7, and a screw 40 can be screwed into it.

Since the door handle seat mounting structure configured as described above does not use the conventional screw fastening means when mounting the door handle seats 11 and 12 arranged inside the door 3 as described later, This eliminates the need for machining screws and screw holes.

On the other hand, the door handle seats 11 and 12 need to be machined into the engagement grooves 15 and 16 and the concave groove 17, which are grooved on the inner surfaces of the flanges 11a and 12a to form a V-shaped cross section. A groove 17 is formed in the end surface of the collar portion 11a of the door handle seat 11 which is attached to the inside of the door 3 while forming the mating groove 15. In this case, the engaging 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 the labor of processing.

Next, when assembling the door handle seats 11 and 12, first, the lock 7 is housed in the lateral hole 4 formed in the door 3 and is fixed by the screw 40 via the front plate 8.

Before and after this, the shaft portion of the door handle 10 is inserted into the through holes 14 and the through holes 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 ends thereof are inserted. A suitable retaining means is provided between the portion and the fixed seat 19, while the door handle seat 11 and the fixed seat 18 are fitted into the through hole 13 and the through hole 20 of the door handle 9 which are attached to the inside of the door 3. The shaft portion is inserted, and an appropriate retaining means is provided between the shaft end portion and the fixed seat 18 and placed.

The shaft ends of the door handles 9 and 10 are inserted into the square holes 37 of the lock 7, and the screw pipes 34 and 34 integrated with the door handle seat 19 are passed through the through holes 6 and 6 from the outside of the door 3. Plug in 6.

On the other hand, the fixed 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 through the screw pipes 34, 34. Screw it in and tighten it.

After fixing the fixed seats 18 and 19 to the inner and outer surfaces of the door 3 in this way, the door handle seats 11 and 12 are pushed into them.

For example, when the recessed groove 17 is positioned on the lower side and the door handle seat 11 is pushed into the fixed seat 18, the inner surface of the flange portion 11 a engages with the flange portion 18 a 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, the inner surface of the door handle seat 11 comes into contact with the outer surface of the fixed seat 18, and when the door handle seat 11 is further pushed in slightly, the convex portion 28 engages with the engaging groove 15, and the convex portion 28 holds the holding piece 24. The engagement groove 15 is pressure-contacted via the elasticity accumulated in the.

In this case, since the convex portion 28 is placed in point contact with the engaging groove 15, the contact surface pressure between them is larger than that in the case where the engaging groove 15 is formed in a curved shape. 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 and the door handle seat 11 does not drop from the fixed seat 18 due to the impact when the door is closed.

Moreover, since the door handle seat 11 is attached to the convex portion 28 while being biased toward the door 3 by a minute amount e, the engagement state with the fixed seat 18 becomes tighter, and the integral thereof Increase

As described above, according to the present invention, since the door handle seat 11 can be attached with one touch, this can be performed easily and quickly, and the complicated screwing work as in the past is not required. The method of attaching the door handle seat 12 and its function and effect are substantially the same as those of the door handle seat 11.

The door handle seats 11 and 12 assembled in this manner are mounted on the bases of the door handles 9 and 10 as shown in FIG. 2, and from the front appearance of them, mounting means such as screws are completely removed. Therefore, the appearance is good and the aesthetic appearance of the inner and outer surfaces of the door 3 is improved.

Moreover, 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 defense ability thereof is improved compared to the conventional one. Further, since the concave groove 17 is located at the lower end portion of the door handle seat 11 and is apart from the normal field of view, it does not spoil the appearance.

When the door handle seat 11 is to be removed, a tool such as a screwdriver is inserted into the groove 17, the tip of the door handle seat 11 is engaged with the door 3, and the opening edge can be removed by pivoting on the fulcrum.
