Hereinafter, the same components as in the prior art will be described with the same reference numerals.

Gear box 10 of the sliding sliding system window lock device according to a preferred embodiment of the present invention, the housing 20 is installed in the window, as shown in Figure 4 to 7, the housing 20 rotates The rotor 30 and the lifter 40 and the rotor 30 which slide up and down in the housing 20 by the rotor 30 so that the operating rod 102 can be lifted up and down by being installed. And a rotational force transmitting member 50 disposed between the lifter 40 and transmitting the force generated when the rotor 30 is rotated to the lifter 40.

In more detail, the housing 20 forms a frame of the gearbox 10, and both sidewalls 22 that are separated from each other are formed to be correspondingly spaced by the fastening member 21 at a predetermined interval. . At this time, the connecting member 21 is made of a rivet. In the central portion of both side walls 22, a coupling hole 23 through which the rotor 30 is rotatably coupled is formed.

In addition, the guide hole 24 vertically penetrates the upper sidewalls 22 of the housing 20. In the guide hole 24, guide walls 26 having curved surfaces protrude outward from both side walls 22 along the periphery.

In addition, a rolling member 28 that is rotated in contact with the lifter 40 is provided at the upper portion of the housing 20. The rolling member 28 has a function of minimizing friction with the housing 20 during sliding of the lifter 40 and is made of a conventional bearing. In addition, the rolling member 28 may be formed of any known rolling member as long as the rolling member 28 is rotated in contact with the lifter 40.

Rotating body 30 is rotated by the operation of the handle (not shown in the figure), both ends are rotatably coupled to the coupling hole 23 of the housing 20 for this purpose. One side of the rotating body 30 is formed to protrude a connection piece 32 for connecting to one end of the rotational force transmission member (50).

The rotating body 30 is installed to be rotatable within an angle range (0 ° to 180 °) set in the housing 20, and rotates by manipulation of a handle according to opening and closing of a window. That is, when the window 30 is closed, the connecting piece 32 is positioned (0 °) at the bottom of the housing 20 when the window is closed, and the connecting piece 32 is positioned 180 at the top of the housing 20 when the window is opened. °) to be rotated.

The lifter 40 is slidably installed along the guide hole 24 in the housing 20 to elevate the operation rod 102 up and down when the window is opened and closed. The second rotating shaft 54 of the rotational force transmission member 50 to be described later is installed to correspond to both side walls 22 of the housing 20 at a predetermined interval. That is, both sidewalls 42 of the lifter 40 are connected to both ends of the other end of the rotational force transmitting member 50 via the second rotation shaft 54. One side of the lifter 40 is formed with a connection protrusion piece 44 for being connected to the operation rod 102.

In addition, an upper portion of the lifter 40 is provided with a spacing support 46 for maintaining the spacing between the side walls 42. The spacing holder 46 cooperates with the second hinge shaft 54 to space the lifter 40 so that both sidewalls 42 of the lifter 40 are spaced apart from both sidewalls 22 of the housing 20 by a predetermined distance. I will catch you. Accordingly, the lifter 40 is slidable such that both sidewalls 42 do not come into surface contact with both sidewalls 22 of the housing 20 when sliding in the housing 20.

In addition, the upper surface of the lifter 40 is formed with a guide surface 48 that is bent at right angles from both side walls 42 and in contact with the rolling member 28 of the housing 20. The guide surface 48 is in contact with the rolling member 28 to minimize the friction generated during the lifting of the lifter 40. This is possible by rotating the rolling member 28 in contact with the guide surface 48.

The lifter 40 is slid along the guide hole 24 in the housing 20 by a force transmitted from the rotational force transmitting member 50 when the rotor 30 rotates, thereby moving the operating rod 102 up and down. It is a structure to move.

Rotational force transmitting member 50 is for transmitting the force generated when the rotation of the rotating body 30 to the lifter 40, for this purpose has a needle-shaped (b) shape that is bent approximately perpendicularly, the end of which It is connected to the connecting piece 32 of the whole 30 via the 1st hinge shaft 52. As shown in FIG. In addition, the other end of the rotational force transmission member 50 is connected via the lifter 40 and the second hinge shaft 54. Both ends of the second hinge shaft 54 are slidably coupled to the guide hole 24.

That is, the second hinge shaft 54 connects the rotational force transmitting member 50 and the lifter 40 as well as both ends of the second hinge shaft 54 to be slidably coupled to the guide hole 24 of the housing 20 so that the lifter 40 is When the rotating body 30 is rotated to be able to slide along the guide hole 24 in the housing 20.

In this case, when the second hinge shaft 54 is slid along the guide hole 24 of the housing 20, the second hinge shaft 54 contacts the guide wall 26 to minimize friction caused by the sliding. This is possible because the guide wall 26 of the guide hole 24 is formed in a constant curved surface and is in point contact with the second hinge shaft 54.

The rotational force transmission member 50 is a structure for transmitting the force generated when the rotation of the rotating body 30 to the lifter 40.

On the other hand, reference numeral '25' represents a stopper for controlling the rotation of the connecting piece 32 so that the rotating body 30 is rotated at a set angle, '34' so that the handle is axially coupled to the rotating body 30. The shaft hole is formed, '39' represents a bushing provided to prevent friction due to the rotation of the rotating body 30 coupled to the coupling hole 23 of the housing 20.

Referring to the operation of the present invention having such a configuration as follows.

In the gearbox 10 of the sliding sliding system window lock device according to a preferred embodiment of the present invention, the connecting piece 32 of the rotating body 30 is first located at the bottom of the housing 20 when the window is closed. By moving the rotational force transmission member 50 and the lifter 40 to the lower portion of the housing 20 by the connecting piece 32 of the rotating body 30, the operating rod 102 is maintained in a lowered state. Reference)

In other words, when the operating rod 102 is lowered, the window is kept locked.

In the above state, when the handle is operated to open the window, as shown in Figure 8, the rotating body 30 is rotated in the upward direction of the operating rod 102, the rotation of the rotating body 30 Accordingly, the connecting piece 32 is rotated in the clockwise direction so as to be positioned above the housing 20.

Then, the rotational force transmitting member 50 connected through the connecting piece 32 of the rotating body 30 and the first hinge shaft 52 is an upper portion of the housing 20 by a force generated when the rotating body 30 is rotated. At the same time, the lifter 40 connected to the rotational force transmitting member 50 and the second hinge shaft 54 by sliding is guided along the guide hole 24 of the housing 20 to operate the rod 102. Is raised.

That is, the second hinge shaft 54 is connected to the rotational force transmission member 50 and the lifter 40, and both ends thereof are slidably coupled to the guide slot 24, so that the lifter 40 has a second hinge shaft. (54) by sliding along the guide hole 24 is to be raised.

Here, the second hinge shaft 54 may slide in contact with the guide wall 26 formed in the guide hole 24 to reduce the friction force between the second hinge shaft 54 and the guide hole 24. This is made possible by the fact that the surface of the guide wall 26 which is in contact with the second hinge shaft 54 is formed in a curved surface and is in point contact with the second hinge shaft 54 through the curved surface.

The rotating body 30 is installed to rotate within an angle range (0 ° to 180 °) set in the housing 20 to open and close the window. That is, when the window 30 is closed, the connecting piece 32 is positioned (0 °) at the bottom of the housing 20 when the window is closed, and the connecting piece 32 is positioned 180 at the top of the housing 20 when the window is opened. °) to be rotated.

When the rotating body 30 rotates at a set angle (90 °), the connecting piece 32 is in a horizontal state, and the rotating body 30 and the rotational force transmitting member 50 by the horizontal state of the connecting piece 32. And the first and second hinge shafts 52 and 54 connecting the lifter 40 are positioned on the same vertical line as the guide slot 24, so that the force due to the rotation of the rotor 30 is maximum in the lifter 40. Can be delivered.

That is, when the first and second hinge shafts 52 and 54 connecting the rotational force transmitting member 50 and the lifter 40 at the set angle of the rotor 30 are positioned on the same vertical line as the guide slot 24. Since the concentration of the force increases, the force generated during the rotation of the rotor 30 can be transmitted to the lifter 40 to the maximum through the rotational force transmission member 50.

It is formed to be orthogonally refracted so that the rotational force transmission member 50 has a substantially needle-like shape, and the first and second hinge shafts 52 and 54 are provided at both ends thereof, so that the rotation angle 30 is set at an angle, That is, the first and second hinge shafts 52 and 54 are positioned on the same vertical line as the guide hole 24 by the shape of the rotational force transmitting member 50 at the maximum load point of the force according to the rotation of the rotor 30. As a result, the concentration of force is increased and the distance between the first and second hinge shafts 52 and 54, which are operating points of the force generated when the rotor is rotated, is minimized.

In addition, the lifter 40 is maintained so that both sidewalls 42 are spaced apart from both sidewalls 22 of the housing 20 by a gap retaining hole 46 that cooperates with the second hinge shaft 54. 20 is slidable so as not to be in contact with the surface, and furthermore, the guide surface 48 is brought into surface contact with the rolling member 28 installed in the housing 20 to be guided along the guide hole 24 to thereby be operated according to the operation of the handle. A smooth lifting operation can be produced by reducing the frictional force during rotation of the rotor 30.

On the other hand, when the handle is operated to close the window, the rotating body 30 is rotated in the downward direction of the operating rod 102 by the reverse order of Figure 8, the connecting piece 32 in accordance with the rotation of the rotating body 30 The counterclockwise rotation is positioned below the housing 20, and the lifter 40 is slid along the guide hole 24 of the housing 20 by the rotational force transmitting member 50 connected to the connecting piece 32. By being guided to lower the actuation rod 102, the window can be locked.
