METHOD FOR ENSURING A TIGHT FIT OF THE DOOR LEAF TO THE FRAME AFTER LOCKING THE BOLT AND PLUG FOR THE MATCHING HOLE FOR IMPLEMENTATION THEREOF Russian patent published in 2021 - IPC E06B7/16 E05B17/00 

FIELD: building.

SUBSTANCE: invention relates to apparatuses of a door leaf frame and can be used in entrance and interior doors to prevent backlash of the door after locking the bolt of a lock or latch in order to ensure a tight fit of the door leaf to the frame. The described technical result is achieved due to the fact that a plug is inserted into the matching hole for the lock crossbar head or the latch crossbar head, provided with fasteners for being retained on the frame, and an outer head part made in size larger than the size of the matching hole whereto the plug is inserted, wherein an elastic insert is installed inside the body of the plug, configured to be fastened relative to the body of the plug, wherein said fastening is ensured by making slots on the elastic insert and matching recesses in the body of the plug, wherein a round hole is made inside the elastic insert for entry of the lock crossbar head or the latch crossbar head thereto, and the axis of said hole is shifted relative to the axis of the body of the plug; to ensure a tight fit of the door leaf to the frame, the plug is adjusted between the door leaf and the frame by extending the insert from the body thereof, rotated to the required angle until backlash is eliminated, then the insert is installed back.

EFFECT: ensured tight fit of the door leaf to the frame and possibility of adjusting the position of the axis of the central hole for the crossbar head with a 360 degree offset, thereby eliminating the need for precise adjustment of the position of the door and the need for adjustment of the position of the door over time in case of subsidence thereof.
