Description

Left and Right Switching Assembly for Cassette Handle}

The present invention relates to a left and right hand switching assembly, and more specifically, to a left and right hand switching assembly of a cassette handle.

In general, a door lock includes a handle, mortise, and parts, and refers to the part responsible for opening and closing the door and securing it. Here, the mortise is installed inside the door and is connected to the handle, allowing the door to be opened and closed by moving the latch bolt left and right as the handle rotates to lock or unlock the door.

These door locks are classified into left-handed type and right-handed type. If the door lock and mortise are installed on the right side, the door lock is called left-handed type. Conversely, the hinge of the door is located on the right side and is connected to the door lock. A door lock in which the mortise is installed on the left side is called a superior type.

In other words, the left-handed type makes it easier for users to open and close the door with their left hand, and the right-handed type makes it easier for users to open and close the door with their right hand.

However, with the conventional door lock handle, the installer determines the insertion direction of the inner handle and the outer handle according to the opening direction of the door in the process of installing the door lock on the door in a left-handed or right-handed manner, and then works.

Therefore, not only does it take a lot of work time, but the constructor only pays attention to the insertion direction of the handle and neglects to connect the inner handle and the shaft, which reduces the durability of the device due to loose screw fastening.

In addition, the conventional door lock handle had to be disassembled and reinstalled in order to change the left or right hand after installation, which raised the problem of poor workability.

In addition, if there is no other definition in the technical and scientific terms used, they have the meaning commonly understood by those skilled in the art in the technical field to which this invention belongs. In the following description and accompanying drawings, descriptions of known functions and configurations that may unnecessarily obscure the gist of the present invention are omitted. The attached drawings are provided as examples so that the idea of the present invention can be sufficiently conveyed to those skilled in the art. Accordingly, the present invention is not limited to the drawings presented below and may be embodied in other forms. Additionally, like reference numerals refer to like elements throughout the specification. It should be noted that like elements in the drawings are represented by like symbols wherever possible.

Referring to Figures 1 to 3, the left and right hand switching assembly of the cassette handle of the present invention is installed in the door lock main body 10 where the handle part 20 is installed.

Specifically, a mounting hole 11 is formed in the main body 10, and the handle portion 20 is inserted into the mounting hole 11 with the bushing member 21 interposed in the mounting hole 11 to install the handle. Left and right rotation of the unit 20 is possible.

Meanwhile, inside the main body 10, the first cassette member 31 and the second cassette member 32 are elastically supported in the vertical direction by a plurality of springs (S). Additionally, a rotation stopper member 50 is installed sandwiched between these cassette members 31 and 32. Here, the rotation stopper member 50 may be formed in a substantially rectangular plate shape. In addition, the rotation stopper member 50 is mounted on the handle shaft 80 (FIG. 5) of the handle portion 20, so that when the handle portion 20 rotates, the rotation stopper member 50 is also rotated.

At this time, the rotation stopper member 50 is rotated at a certain angle by the first cassette member 31 and the second cassette member 32, which are in close contact with each other at the top and bottom, so that it returns to its original state by the pressing force acting in the vertical direction. do.

That is, as shown in FIG. 2, the handle unit 20 can be returned to its original state by the cassette members 31 and 32 located above and below, without providing a separate torsion spring in the handle unit 20. That is, when the user rotates the handle unit 20 as shown in (b) of FIG. 2 and then releases the handle unit 20, the rectangular rotation stopper member 50 is caused by the pressing force disposed above and below the rotation stopper member 50. ) returns to the original posture (state in (c) of Figure 2).

Referring to Figure 3, the present invention provides a setting member 40 to easily switch between the left and right hands without separate door lock disassembly. That is, by manipulating the setting member 40, the handle unit 20 can be easily converted from, for example, a left-handed type to a right-handed type.

Specifically, referring to FIG. 4, the rotation stopper member 50 has a rotation rim 53 formed in the shape of a circular ring on one side, and locking portions 51 and 52 on both sides of the rotation rim 53, respectively. is formed At this time, a turning area 54 corresponding to the turning angle of the handle part 20 is formed between the locking parts 51 and 52. That is, the turning angle of the rotation stopper member 50 corresponds to the turning area 54, which is a range in which the locking parts 51 and 52 are not caught.

Meanwhile, a shaft coupling hole 56 is formed in the center of the rotation stopper member 50, and when the handle portion 20 is mounted, the handle shaft 80 is inserted into the shaft coupling hole 56 and the fixing bolt 60 ; Figure 1) achieves a fixed state.

In addition, as shown in FIG. 3, the support end 45 of the setting member 40 is caught by the locking portions 51 and 52 formed on the rotation stopper member 50 to prevent the handle portion 20 from rotating beyond a certain angle. You can. That is, by configuring the support end 45 of the setting member 40 to be caught on the locking portions 51 and 52, the effective rotation angle of the handle portion 20 is limited (see Figure 3 (a)).

Therefore, the present invention provides a structure in which the left and right hands can be changed by rotating the handle unit 20 by more than 180 degrees without disassembling the handle unit 20 when changing the left and right hands in this structure.

Specifically, a setting member 31 is installed in the first cassette member 31 to be able to move up and down. Here, the setting member 31 is composed of an approximately 'ㄴ' shaped piece in which the first end 41 and the second end 42 are bent at a right angle, as shown in FIG. 6. At this time, a locking protrusion 43 is formed at the first end 41, and a tension spring 90 is mounted on this locking protrusion 43 as shown in FIG. 5, and this tension spring 90 is connected to the first cassette member 31. ) is fixed to the spring fixture 35 provided. Accordingly, as shown in FIG. 3, the setting member 40 is normally lowered by the tension spring 90 as shown in (a) of FIG. 3, so that the angle of the handle unit 20 (the turning angle of the rotation stopper member) plays a limiting role.

Meanwhile, when the setting member 40 is lifted from the first cassette member 31 as shown in Figure 3 (b), the support end 45 of the setting member 40 is connected to the locking portion 51 of the rotation stopper member 50. The handle unit 20 can be freely rotated without a limiting angle (i.e., out of the interference area).

Therefore, in this way, the setting member 40 is lifted against the elastic force of the tension spring 90, and in this state, the handle part 20 is switched to more than 180 degrees, making it possible to change the left and right hands (normally, the setting is set by the tension spring). member remains lowered). That is, when the setting member 40 is placed again after switching the handle portion 20 in the desired direction, the setting member 40 descends in a state where the left and right sides are switched as shown in (a) of FIG. 3 and moves to the top of the turning area 54. The support end 45 is located on the, and the locking parts 51 and 52 of the rotation stopper member 50 are again caught by the setting member 40, thereby limiting the turning angle of the handle part 20. there is.

Therefore, through the present invention, it is possible to change the left and right hands of a handle having a cassette structure simply and quickly.

In the above, the present invention has been shown and described with respect to specific embodiments, but the present invention is not limited to the above-described embodiments, and those of ordinary skill in the art to which the present invention pertains will appreciate the present invention described in the following claims.
