Problems solved by technology

[0006] However, in this conventional lever type door lock device, except for a part of the latch operation body 1, the remaining space of the fitting hole becomes left as an unnecessary space (empty space)
This leads to the problem of reducing the durability of door D
[0007] In addition, in the conventional lever type door lock device, since the connection body for connecting the latch operation body 1 to the external driving unit is provided outside the door D, it is difficult to miniaturize the device
In addition, since the drive unit is usually manufactured in a part of the door lock (product model-specific), the drive unit differs depending on the door lock product, and the drive units are not compatible with each other
This leads to the problem of reducing the general application of

Embodiment 1

[0042] refer to Figures 2 to 4 , drive assembly 100 ( Figure 4 ) is directly connected to the latch operating body 20. In this case, a circular mounting hole H with a diameter of approximately 54mm ( figure 1 ) is formed in gate D. The driving assembly 100 is fitted in the mounting hole H. As shown in FIG.

[0043] At this time, the driving assembly 100 has a shape and area corresponding to the mounting hole H, and is fitted in the mounting hole H. Referring to FIG.

[0044] Specifically, the latch operation body 20 is installed such that the latch bolt 21 can be pulled out at the end of the latch operation body 20 . Furthermore, a mounting plate 30 is fitted into an end of the latch operating body 20 . The mounting plate 30 is fixed to the side surface of the door D, as Figure 4 shown. On the other hand, the latch operating body 20 is provided with a pivoting portion 25 for pulling out the latch bolt 21 by rotation ( image 3 ). The second shaft 42 of the drive as...

Embodiment 2

[0060] According to FIGS. 11A and 11B , the case is formed by connecting the first case 10 a and the second case 10 b to each other. A plurality of gears and a drive motor 15a are installed in these housings 10a and 10b.

[0061] Specifically, a motor fitting portion 15b having a predetermined space is provided in the first housing 10a (see Figure 19 and Figure 20 ). The driving motor 15a is contained in the motor fitting portion 15b of the first housing 10a. A motor gear 16a is fitted on the drive shaft of the drive motor 15a, and the motor gear 16a is connected to mesh with the intermediate gear 16b. At this time, the intermediate gear 16b is rotatably fitted inside the housing by the second pin P2. The intermediate gear 16b is connected to mesh with the driven gear 16c. At this time, the driven gear 16c has a rotation shaft 16d extending to one side, and the worm wheel 18 is fitted at the end of the rotation shaft 16d through a spring S fitted on the rotation shaft 1...

Abstract

The present invention discloses a lever type door lock driving assembly, which can be installed in a fitting hole, to enable miniaturization of the device, ensure general versatility, and prevent a fragile area from being generated inside a door. The invention relates to a drive assembly for a lever type door lock arranged in a mounting hole to drive a latch operating body, wherein the assembly assembly comprises: an assembly module having a truncated disc shape and having at least one drive therein a plate; and a motor unit fitted on the truncated area of ​​the fitting module and having a disc shape in a state coupled to the fitting module.

Description

technical field [0001] The present invention relates to drive assemblies for lever-style door locks, and more particularly to drive assemblies for lever-style door locks that fit in mounting holes. Background technique [0002] In general, a lever-type door lock device is a device that drives a deadbolt or a latch bolt to set and release a lock by turning one of an indoor-side lever and an outdoor-side lever. [0003] Such lever-type door lock devices include a door lock capable of locking and unlocking a door only on an indoor side and a door lock capable of locking and unlocking a door both on an indoor side and an outdoor side. [0004] figure 1 is a state diagram showing an installed state of a conventional lever type door lock device. [0005] refer to figure 1 , in a conventional lever type door lock device, a mounting hole H having a diameter of about 54 mm is formed by drilling the door D, and the latch operating body 1 is fitted in the mounting hole H. At this t...
