Description

LOCKING DEVICE FOR WINDOWS AND WINDOWS INCLUDING THE SAME

The present invention relates to a locking device for windows and doors and windows including the same.

Recently, a horizontally close-type misseogi window has been developed among the Miseogi windows. Such a horizontal contact type misseogi window, the window jjak can be moved to the outdoor side and the indoor side, it has the effect of increasing the adhesion between the window and the fixed window.

However, there was no separate locking device for maintaining the close contact between the window sill and the fixed window in this horizontal contact type misseogi window. Therefore, there is a problem in that water leakage and leakage occur due to the blank space between the window sill and the fixed window, and deformation due to wind pressure occurs.

In addition, due to the blank space between the window sill and the fixed window, there is a problem in that heat loss increases.

An object of the present invention is to provide a locking device for windows and doors in which close contact between a window sill and a fixed window is maintained, and a window including the same.

In one example, the locking device for windows and doors is provided to be coupled to a window leaf movable in a reference direction between the outdoors and indoors, is disposed on the outdoor side compared to the window leaf, and when viewed from the outdoor side, at least partially overlaps with the window leaf It is provided to be disposed in a fixed window insertion groove formed by a locking portion protruding from the window sill and a portion of the fixed window recessed toward the fixed window disposed to be, and when the changjjak moves in the reference direction, the engaging portion is inserted, and a guide part for guiding the locking part so that the locking part moves in a direction from the indoor to the outdoor.

In another example, the locking part is formed in the form of a column extending up and down, an upper opening is formed on the upper side, and a locking part body having a lower opening formed on the lower side, a first insertion member partially inserted into the upper opening, and an upper and lower part An upper rotating member including a first bushing coupled to an upper side of the first inserting member so as to be rotatable about an axis extending in the direction, and a second inserting member partially inserted into the lower opening, and rotatable about the axis It may include a lower rotating member including a second bushing coupled to the lower side of the second insertion member.

In another example, the first insertion member may be formed to be inserted into the upper opening so that the degree of insertion can be adjusted, and the second insertion member, the degree of being inserted into the lower opening can be adjusted to be adjustable.
