Description

Door lock of right and left combination

The present invention relates to a left / right door lock device for locking and releasing the door by rotating the handle 90 ° to the left and right, and more specifically, the left / right door can be installed by rotating the door 180 ° in the unlocked state. Right side door lock.

A door lock device including a conventional window is mainly provided in a sliding door and is formed with a latch that rotates at the same curvature as the handle, so that the latch is caught or separated from the corresponding fastener to control the locking or unlocking of the door (eg For example, there is a crescent) and a locking protrusion protrudes in a direction perpendicular to the fixed shaft of the handle so that the locking hook is caught by the frame of the window so as to control the locking or unlocking of the window (for example, the project handle). .

In the case of the project handle is formed in the direction perpendicular to the fixed shaft of the handle of the handle is typically provided with a single locking unit on one side of the head of the handle is divided into the right or left for the handle according to the direction of the latch If the direction of use is fixed as described above, only the handle of the project manufactured for the corresponding purpose should be used according to the installation environment, which causes troublesome work.

As described above, there are a number of techniques for using a conventional project handle that can be used only on one side to both left and right sides. An example thereof will be described below.

First, in Utility Model Registration No. 20-0384270 (window project handle), as shown in Fig. 1 and Fig. 2, the handle 10 and the latch 20 are separated, and the cutout portion 11 is disposed on the handle 10. Puncture the hole 12 having a pin, and insert the pin 15 having the compression spring 13 and the pressing piece 14 into the hole 12, and the pin above the locking hole 20. The two grooves 21 are fixed to each other, and the handle 10 is rotated in a state in which the worker lifts the pressure piece 14 upward by hand, so that the grooves 21 are fixed in the direction of the handle 10 among the plurality of grooves. The pin 15 is inserted into one groove 21 according to the configuration, and the locking hole 20 has a configuration in which the moving position is fixed by the fixing groove 22 and the ball plunger 31 formed at the bottom thereof. However, in this case, due to the incidence portion 11 formed in the hole 12 for vertical movement of the pin 15, the fluctuation is severe, as well as the ball plunger 31 and the latching hole 20 ), Because of the shaking caused by the assembly tolerances with the fixing piece 30, the lack of durability when mounted on the actual window caused a problem that the locking function is insufficient.

In another embodiment, Utility Model Publication No. 195-0006229 (window lock) forms two pairs of insertion grooves diagonally on the handle, and protrudes a pair of protrusion pieces inserted into the insertion grooves into the locking holes. It is operated to the left / right direction according to the insertion groove insertion position of the stone piece, but in this case, the handle can be rotated only when the handle is completely spaced from the catch, but there is no configuration to separate the handle from the catch. The adjustment was possible only when the was separated.

The present invention has been devised in view of the above-mentioned problems, so that the handle and the fastener can be separated and connected by a simple operation. It is to provide a left and right door lock device to simplify the assembly and to simplify the assembly.

In addition, it is an object to strengthen the durability by reducing the swing of the handle by preventing the tolerance occurs in the assembly process.

A feature of the present invention for achieving the above object is in the door lock device consisting of a handle, a locking mechanism and a fixed piece, the shaft of the handle is inserted into the center of the body formed in a cylindrical shape and the outer circumference of the shaft of the handle A plurality of guide shafts are formed to be symmetrically protruded symmetrically in the lower end portion, and the shaft hinges are formed in the body so that the inclined grooves are symmetrically upward from the ends of the guide shafts, and the cylindrical hinges are inserted to insert the shaft hinges. The inner circumferential surface of the guide rod engaging with the inclined groove of the shaft hinge is formed to protrude in a dimension corresponding to the inclined groove, the outer side of the directional hinge with a projection key for the user to operate, and the locking to control the door lock and unlocking on one side A piece protrudes and a ring-shaped step is formed on the inner circumferential surface, and the guide shaft is inserted into the upper surface of the step. The guide grooves are formed to be symmetrical, and the fixing piece perforated by the insertion hole into which the shaft rod of the handle is inserted in the center is arranged in sequence on the outer periphery of the shaft rod, so that the locking mouth can be turned 180 °. The handle can be selectively operated left or right.

The present invention allows the left and right parts to be used in combination by the simple operation of the direction keys according to the construction location or location, and the direction change process is simple and accurate since the operator only needs to operate the direction key to change the direction. This has the effect of improving the satisfaction on use.

In addition, the components can be easily assembled through riveting after aligning the components about the shaft of the handle in a straight line, thereby significantly reducing the assembly labor.

In addition, the assembly tolerance is reduced by matching the size of the guide shaft and the guide groove with each other to minimize the fluctuation when the handle is combined has the effect of strengthening durability and locking function.

Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.
