Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking ball and a lever handle seat for preventing loosening and falling.

[0002]

2. Description of the Related Art A description will be given with reference to FIG. In the past, there was no prevention of loosening of the mounting screw, whether a Kikuza washer was sandwiched between the mounting screws, or a loosening preventive agent was attached to the screw portion. All of them did not stop completely loosening, many mounting screws were loosening, the mounting seat was wobbled, and wobbles were seen on the external and internal makeup seats that were attached by sandwiching the door with the mounting seat. Almost all of the play balls on the outer side have looseness of the mounting screws. At the same time, the looseness of the connected inner grip balls also occurs. The mounting seat is usually a hidden cover that is hidden inside the internal makeup seat, the mounting screws cannot be seen from the outside, and even if the layman loosens, the screws cannot be tightened. Often continue to be used until the looseness expands and the lock becomes unusable. The structure and attachment method of the seat of the lever handle are also the same because many of them are the same. However, the lever handle body is installed separately from the seat, and even if the seat loosens, the lever handle will not loosen and will not fall out, but the seat serving as the bearing of the lever handle will loosen and the lever handle will be wobbled. Occur. Looseness of the grip ball Another cause of the looseness is the loosening of the internal cosmetic seat that is screwed into the mounting seat. The looseness of the inner grip ball is this looseness. If the looseness becomes large, the inner handball will come off from the mounting seat and the inner makeup seat will fall off. This double-sided cylinder lock is a monolock double-sided cylinder lock that has a cylinder inside and outside the grip ball as a lock to prevent the cosmetic seat from loosening.You cannot remove the cosmetic seat without inserting the key or opening the door. This is because it is difficult to remove the locked state for the purpose of the double-sided cylinder lock. Therefore, the loosening prevention structure is complicated,
I don't want to use it for ordinary tablets.

[Problems to be Solved by the Invention] In order to eliminate wobbling of grip balls or lever handles and drop-out of grip balls, it is necessary to completely remove the looseness of the mounting screws that are tightening the mounting seats and to screw them into the mounting seats. It is to completely eliminate the looseness of the inside grip ball.

[0004]

[Means for Solving the Problems] As a means for preventing loosening of a mounting screw, a loosening stopper having a hole matching the shape of the mounting screw head is combined with the mounting screw head to prevent the mounting screw head from rotating and loosening. lost. As a means to prevent loosening and disengagement of the loosening prevention metal fittings, it was prevented by screwing the inner side decorative seat into the mounting seats so that the combined loosening prevention metal fittings were sandwiched above the mounting seats. As a means to prevent the internal cosmetic seat from loosening with respect to the mounting seat, the internal cosmetic seat and the mounting seat are sewn with pins so that the internal cosmetic seat does not rotate. In order to prevent the inserted pin from falling off, a retaining spring was installed on the pin, and the pin penetrated to expand the spring, preventing the pin from falling off or loosening. With the above, it is possible to completely prevent loosening and dropping. If it comes loose or comes off, the lock is just broken or damaged.

BEST MODE FOR CARRYING OUT THE INVENTION An explanation will be given based on the drawings. The method for attaching the handball according to the invention will be described with reference to FIG. The outer side decorative seat (2) outside the door and the mounting seat (5) inside the door sandwich the door for installation. Attach the mounting screws (11) to the holes in the mounting seat.
Fix the outer cosmetic seat and the mounting seat to the door by screwing it into the mounting bar (3) through (6). Cover the mounting screw on the mounting seat with a locking metal fitting (8) that prevents the mounting screw from loosening. The mounting screw heads (12) are square, hexagonal,
Other than a circular shape such as an ellipse is effective, and the receiving hole (10) of the locking metal fitting should match the shape of the screw head. This will prevent the mounting screws from loosening. Next, the internal cosmetic seat (16)
Install by screwing onto the decorative screw on the inner side of the mounting seat (7). The locking metal is fixed by being sandwiched between them. This is claim 1. FIG. 5 is a view for explaining the attached state by a cross section. The locking metal fitting (8) is sandwiched between the mounting seat (5) and the interior decorative seat (16) and does not move. Next, align the pin hole (13) of the inner side cosmetic seat with the pin hole (9) of the mounting seat, and insert the pins (14) so as to sew both pin holes to stop the loosening of the inner side cosmetic seat. This is claim 5
Is. It is FIG. 6 and FIG. 7 which show the modification of the shape of the loosening prevention metal fitting. FIG. 6 shows a modification of claim 5 for stopping the loosening of the inner side dressing seat, replacing the pin hole of the mounting seat with the pin hole (29) of the loosening stop fitting (27) to replace the loosening stop fitting and the inner side dressing seat. It sticks a pin. Fig. 8 shows the locking metal
The locking metal according to claim 2, wherein the hole for receiving the screw head of (33) is replaced with the groove (34). The drawing shows one receiving groove, but a plurality of receiving grooves may be used. The method of combining with the mounting seat is by covering or sliding and sandwiching. The figure shows a rotating shaft that is rotated and sandwiched. 9 and 10 replace the locking metal with the pins (40) and (42), and pass the pins through the pin grooves (39) (46) of the screw head and the pin fixing holes (37) (44) of the mounting seat to attach screws. It is a figure explaining Claim 3 which stops looseness of. By using a pin, the shape of the screw head does not matter, and it can be stopped with a circular screw head. Figure 12 shows mounting screw head (49)
It is a figure explaining Claim 4 which covers a screw cap (50) on.
When the screw cap rotates, it hits the inner periphery of the inner cosmetic seat and stops rotating. Also, there is an internal makeup seat on the top so that it will not come off. FIG. 11 shows a makeup seat loosening prevention mechanism according to a fifth aspect. After screwing the internal decorative seat (16) into the mounting seat (5) as much as possible, align the pin holes (9) of the mounting seat and the pin holes (13) of the internal seat so that both pin holes are aligned. Insert the pin (14) into the. Further, the pilot hole (47) and the pilot pin (48) according to claim 6 are shown. If you turn the inner cosmetic seat while inserting the pilot pin into the pilot hole, the pilot pin will hit the protrusion with the pin hole on the mounting seat and stop. That position is the position where both pin holes are aligned. In the case of the modified example of claim 5 in which the pin hole of the mounting seat of FIG. 15 is replaced with the projection (76), when the internal decorative seat rotates, the pin hits the projection of the mounting seat and stops rotation, so alignment is necessary. There is no. FIG. 13 is a modified example of claim 1 for stopping the loosening of the lever handle mounting screw. The structure and mounting method of the lever handle seat are the same as the structure and method of mounting the grip ball on the door, and the size is only small. Attach the locking bracket (59) to the screw head of the screw.
The rotation of the mounting screw is stopped by covering it with (62), and the inner side decorative seat (63) is screwed into the mounting seat (58) with the locking metal fitting sandwiched therebetween. Next, it is a modification of claim 5 that a pin (66) is sewn into the pin hole (65) of the inner side cosmetic seat and the pin hole (57) of the mounting seat to stop the loosening of the inner side cosmetic seat. is there. Figure 1
4 is a modified example of claim 1 when the lever handle is long seat. The inner cosmetic seat (74) is pushed by covering the mounting seat (68), and the groove of the mounting seat is aligned with the protrusion of the internal cosmetic seat, and the internal cosmetic seat is not screwed.

(Cause of loosening screws) With respect to general wooden doors excluding high-grade doors, drying progresses from the second half year to one year after the construction, and the thickness of the door becomes thin and thin compared to the dryness at the time of new construction. Loose mounting screws. After that, the door is thin. For all doors, the mounting screws loosen due to the vibration of the door due to the opening and closing of the door. I haven't tightened the mounting screw well because the grip ball will not turn if the screw is properly tightened due to the position of the notch hole that was opened to mount the lock. The above is the cause of loosening the mounting screw. The cause of the loosening of the inner cosmetic seat with respect to the mounting seat is that the resistance between the inner cosmetic seat and the grip ball is great when the notch position is displaced, and when the grip ball is rotated, it will rotate to the inner cosmetic seat. At this time, it is easier to turn in the loosening direction than in the tightening direction. Loosens due to vibration of the door when opening and closing. That is all.

(Current situation) We inspected, adjusted, and repaired tens of thousands of locks for 30 years from 1968, but in the wooden door of a general building, more than 90% of the mounting screws were a little over 3 years after new construction. Looseness has occurred. If it is tightened at that time, loosening after that will be less. If left unattended, the looseness will increase and eventually it will become unusable. The looseness of the internal cosmetic seat increases with the looseness of the mounting screws. Loose mounting screws are seen in steel doors at around 5-20%. If it is left unattended, the looseness will increase and it will eventually become unusable. In the case of any of the doors, loosening of both the mounting screw and the inner side cosmetic seat is often seen when the position of the cutout hole is displaced, and especially the inner side cosmetic seat loosens quickly and there is a risk of falling off. About six years ago, as soon as I entered the toilet and closed the door, the ball inside the ball fell off, causing an accident in which the grandmother was trapped for two days. At that time, I asked the manufacturer for improvement, but I was refused if I could not, so I can not see anything improved. It is impossible for an amateur to check and repair the loosening of the mounting screws and the loosening of the internal cosmetic seat, so it is necessary to have the mounting screws and the internal cosmetic seat that never loosen.

[0008]

EFFECTS OF THE INVENTION If the loosening prevention mechanism of the invention is used, the mounting screw and the internal decorative seat will not loosen. If you loosen it, it is about the time of installation work or when the lock is broken. The looseness of the clasp is uncomfortable and you can use it comfortably and comfortably by not loosening it.
