Description

[Detailed Description of the Invention] The present invention relates to a door locking device that makes it possible to incorporate a latch and internal and external operation parts for operating the latch into a relatively thin door.

An embodiment of the present invention will be described below with reference to the drawings.A is a door, B is a pillar, and inside and outside of the door there are inner operation parts A1
and an outer operating section A2 are provided, and the inner/outer operating section A1. A latch portion A3 having a structure independent from A2 is provided.

Hanging B is provided with a catch B1.

The frames 1 and 2 of the inner and outer operating parts are located inside and outside the door and are screwed together by screws 3.
Fixed by

A vertically movable plate 4 is provided on the inner frame 1, and an operating knob 5 thereof protrudes.

A cylinder lock 6 is provided on the outer frame 2, and a driving piece 7 provided on the outer periphery of a part of the rotor engages with a driven pin 8 of the vertically moving plate 4, thereby causing the cylinder lock to move up and down when the cylinder lock is operated. Moving plate 4
to drive and operate.

A connecting pin 9 is provided at the top of the vertically movable plate 4, and the pin 9
is engaged with a connecting hole 12 of a vertically movable plate 11 provided in the frame body 10 of the latch portion A3.

Reference numeral 13 denotes a latch, which is rotatable about a shaft 15 located in the elongated hole 14 of the vertically movable plate 11, and the rear end of the latch 13 is connected to the vertically movable plate 11 by a shaft 16. They are connected, and the hook portion at the tip moves in and out by vertically moving the vertically movable plates 4 and 11.

17 is a spring that engages with the engaging portions 11 a and 11 b of the vertically moving plate 11 to determine its vertically moving position; 18 is a pillar B of door A;
This is a movement permitting pin for the vertically movable plate 11 that allows the latch 13 to be operated to protrude only when the closed state is confirmed.

As described above, the present invention forms the inward/outward operating section and the latch section as separate bodies, and connects the vertical moving plate of the inward/outward operating section and the up/down moving plate that drives the latch of the latch section. It is possible to easily deal with the difference in left and right hand of the operating member, and the inner operating part and the outer operating part are provided facing each other on the outside and outside of a relatively thin door, and the door is operated by the inner and outer operating parts. The latch part can be incorporated, and since the vertical movement plate is driven by the engagement of the driving piece of the Shinonda lock with the driven pin of the vertical movement plate, play can be provided between both, making it easy to operate from inside and outside. It has features that can be made possible depending on the configuration.

Claims (1)

[Scope of utility model registration request] An inner operating part having an operating knob and an outer operating part having a cylinder lock are provided facing the inside and outside of the door, and an independent latch part is incorporated above or below the inner/outside operating part, and a vertically moving plate of the inner/outside operating part is installed. A vertically moving plate that drives the latch of the latch portion is connected by a pin and a hole, and a driving piece provided on the cylinder lock is engaged with a driven pin of the vertically moving plate, so that the vertically moving plate is activated when the cylinder lock is operated. A door locking device characterized by locking and unlocking by drive operation.
