The door handle connecting structure according to claim 1, wherein the door handle connecting structure is bent toward and is elastically deformed when the core member is inserted into the hole.

Since the locking piece is bent toward the inner side of the recessed hole and elastically deforms when the core member is inserted into the hole, it can be easily inserted. Further, after the insertion, since the locking piece is bent and contacts toward the inner side of the recessed hole, when the pulling force of the core member acts, the locking piece presses the core member, and the pulling strength is further increased. can do. The depth of the recessed hole is the direction opposite to the entrance for inserting the core member.

The invention according to claim 3 is the door handle connecting structure according to claim 1, wherein the locking plate is arranged obliquely with respect to the core member.

Since the locking plates are arranged obliquely, the stress at the contact portion after fixing can be made larger than that when they are arranged vertically, and the pull-out strength is further increased. further,
If the structure is such that, when the core member is inserted, the locking plate is movable in a state of being perpendicular to the core member, the insertability of the core member becomes easier and the attachment becomes easier.

The invention according to claim 4 is characterized in that the core member has a corner portion at the outer peripheral portion of its cross-sectional shape, and the corner portion of the core member contacting the locking plate is the outer peripheral portion. The door handle connecting structure according to claim 1, 2, or 3.

Since the outer peripheral portion of the cross-sectional shape of the core member has a corner portion, and the corner portion of the core member that contacts the locking plate is the outer peripheral portion, the shape of the hole of the locking plate and the shape of the core member. Can have a non-complicated shape and is easy to process.

The invention according to claim 5 is characterized in that the core member has a groove, and a corner portion of the groove contacts the locking plate. It is the handle connection structure for the door described.

When the core member has a groove, the number of corners increases and the number of contact portions can be increased as compared with the case where the core member does not have a groove, so that the pull-out strength can be further increased.

FIG. 7 is a cross-sectional view taken along the plane A perpendicular to the axial direction near the entrance of the recessed hole 18, and as shown in this figure, the hole 18a has an axial direction of 180 °.
It has two grooves 18d at every other angle. The direction of the grip 17 and the direction of the depth of the recess 18 are substantially at right angles.

The recess 18 has a locking plate 19 and a cylindrical body 20.
Is inserted. As shown in FIGS. 1 and 2, the locking plate 19 has a substantially disk shape having a square hole 21 in the center, has a convex outer convex portion 23 on the outer periphery, and has an inner engaging portion on the inner side of the hole 21. It has a stop 22. The holes 21 are the square holes 6a and the square holes 18b.

This is a portion in which the ends of the four sides of the inner hole 21 are bent toward the inner side of the concave hole 18. In addition, the outer convex portion 23
Is a portion in which a convex portion outside the locking plate 19 is bent toward the entrance side, and is located on a pair of diagonals inside the hole 21 on the inside. The length of the bent portion of the inner locking piece 22 is about 0.5 mm to 3 mm, preferably 1 mm to 2
mm. The angle of the bent portion of the inner locking piece 22 is 20 ° to 70 °, preferably 30 ° to 50 °.
Is. The projection surface from the axial direction of the outer convex portion 23 is the groove 18
It is almost the same as d. When inserting the locking piece 19 into the concave hole 18, the engaging piece 19 is inserted together with the outer convex portion 23 and the groove 18d.

The shape of the cylindrical body 20 is a square hole 20 passing through the center.
It has a cylindrical shape having a. The body has a two-stage structure including a small diameter portion 20b and a large diameter portion 20c. The outer diameter of the large diameter portion 20c is slightly smaller than the inner diameter of the hole 18a on the entrance side of the recessed hole 18. The square hole 20a is substantially the same as the square hole 6a and the square hole 18b, and is slightly smaller than the outer diameter of the core member 13. Then, at the time of insertion, the locking plate 19 including the outer convex portion 23 and the groove 18d is inserted first, and the tubular body 20 is inserted with the small diameter portion at the back. At this time, the square of the square hole 18b and the hole 21
The squares are shifted by 45 ° and cannot rotate.

The door 2 has a lock 3 and a pair of handle levers.
When attaching No.4, proceed as follows. First, the lock 3 is inserted into the recess 7 of the door 2 and attached. At this time, the through hole 5 and the square hole 6a of the door 2 are communicated with each other, and the core member 13 is inserted in the communicated state. Further, the recessed hole 1 of the other lever handle 12 in which the locking plate 19 and the tubular body 20 are inserted into the recessed hole 18
Insert the core member 13 into 8. When the core member 13 is inserted, the core member 13 has a circular hole 5, a square hole 6a, and a square hole 20.
a, the square hole 21 and the square hole 18b. When the lever handle 10 on one side and the lever handle 12 on the other side are pushed from both sides of the door, the core member 13 further goes into the concave hole 18. Then, the core member 13
The length of the exposed portion of the door depends on the thickness of the door 2 and the concave hole 1.
Because it is slightly shorter than the total depth of 8
The tip of the core member does not hit the bottom of the concave hole 18, and the square hole 18b
It cannot be inserted because it is located at the part.

Since the circular hole 5, the square hole 6a, the square hole 20a and the square hole 18b have substantially the same shape as the core member 13, the circular cam 6, the cylindrical body 20 and the square hole 18b portion of the other lever handle 12 are formed. Then, there is almost no contact and there is no gap. The square of the square hole 18b and the square of the hole 21 of the locking plate 19 are 45
It is in a state where it cannot be rotated when it is out of alignment.
The hole 21 has a size of a square formed by connecting the midpoints of the sides of the square of the hole 21 slightly smaller than the core member. Therefore, when the core member 13 is inserted into the square hole 18b, the corners of the core member 13, which correspond to the four vertexes of the square, contact the inner locking pieces 22. Then, the contacting portion of the inner locking piece 22 is deformed. Further, since the inner locking piece 22 is bent toward the rear side of the recess hole 18, when the core member 13 is inserted into the recess hole 18, the inner locking piece 22 is elastically deformed toward the rear side of the recess hole 18, Since 21 is deformed so that the projection surface in the axial direction becomes large, it is easy to deform and easy to insert. In addition, when it is pulled in the axial direction after insertion, it is elastically deformed toward the entrance side of the recessed hole 18, and the hole 21
Deforms so that the projection plane in the axial direction becomes smaller, which makes it difficult to deform and increases the pull-out strength. Furthermore, since the core members 13 are in contact with each other at the corners, the contact area is small, so that the stress at the contact portion is high and the pull-out strength is high.

With the lever handle attached,
Since the core member 13 of one lever handle 10 is in contact with the square hole 18b of the other lever handle 12 without a gap, rotation and torque are transmitted between the one lever handle 10 and the other lever handle 12. Further, as another method of transmitting rotation and torque between the one lever handle 10 and the other lever handle 12, a convex portion or a concave groove is provided on the outside of the cylindrical body 20 in the axial direction, and the other lever handle A concave groove or a convex portion corresponding to the convex portion or the concave groove may be provided inside the concave hole 18. In this case, rotation and torque can be transmitted between the one lever handle 10 and the other lever handle 12 via the tubular body 20. Further, a hole penetrating from the outside of the concave hole 18 toward the center of the shaft is opened, and a fixing pin is inserted from the outside by a screw or press fitting to fix the tubular body 20 inside the concave hole 18 of the other lever handle. It is possible to prevent the tubular body 20 from coming off in the axial direction. Further, when one lever handle 10 or the other lever handle 12 is rotated, the core member 13 is rotated, so that the rotating cam 6 is rotated and the latch 8 is moved in and out.

When removing the pair of lever handles 4, the outer convex portion 23 is pushed inward from the opening window 18g with an appropriate tool to deform the locking plate 19 into a convex shape toward the inner side of the concave hole 18. The locking piece 22 is opened to the outside to release the engagement between the locking piece 22 and the core member 13.

Next, a door handle connecting structure 1'which is a modified example of the present invention will be described. The door handle connecting structure 1'is different from the door handle connecting structure 1 according to the first embodiment of the present invention only in the shape of the core member 13 'and the shape of the hole of the locking plate.

The two sides including the corner 21a having an angle of 80 ° or more have the inner locking pieces 22 and the other sides have substantially the same length. In other words, the hole 21 'has a shape obtained by removing the obtuse isosceles triangle from the square, and the inner locking pieces 22 are located on the two sides of the removed obtuse isosceles triangle. Then, when inserting the core member 13 'into the hole 21' of the locking plate 19 ', the core member 13' is in contact with the inner locking piece 22 of the locking plate 19 'at the corner 13b of the groove 13a, Two corners 21
The locking plate 19 'and the core member 13' are fixed by being pressed against the side including b.

In the above-described first modification, the corners of the core member 13 'and the inner locking pieces 22 contact at two places. Further, the corners of the outer peripheral portion of the core member and the inner locking pieces 22 contact each other. The locking plate is changed so as to make it possible, or the groove is provided not only at one place but also at a plurality of places to further increase the number of contact angles and increase the pull-out strength of the pair of lever handles 4. be able to.
