Description

Windows with telescopic devices

The present invention relates to windows and, more particularly, to windows that can be opened and closed by sliding.

A window or door is a window and door that separates the interior from the exterior to prevent the wind from entering the room or to ventilate the room. The structure is basically a frame (or door frame) and its interior. It consists of a window (or door) mounted on it.

Windows and doors are distinguished by either opening or sliding doors or fixed doors. Also, depending on the number of window frames (or doors) installed in one window frame (or door frame), it may be classified into single window, double window, and triple window, and the glass fitted into the window is separated by single glass and two single glass. Insulated gas is injected into the space part or the space layer is formed to separate the laminated glass and three single plate glass which have improved insulation and sound insulation performance, respectively, and inert gas is injected into the space part or the space layer is formed to insulate and sound insulation. It can also be classified as triple (or triple) glass with improved performance. There are also various classifications.

The upper end of the connector body 15a may be located inside the connector insertion space 59.

The connection part body 15a may be made of the same material as the moving frame 12. That is, the connection unit body 15a may be made of a material having high thermal conductivity such as aluminum or steel.

Therefore, in order to prevent heat from being conducted between the window 50 and the window frame frame 40 through the connection body 15a, the heat insulating part 15b may be provided to surround the connection body 15a. In more detail, the heat insulating part 15b may surround a portion of the connection body 15a positioned in the connection part insertion space 59.

Since the length of the window frame 40 is longer than the length of the window 50, the overall length of the connection portion through-hole 63 may be longer than the lower connection portion 15. For example, the length of the connection part passing hole 63 may be approximately twice as long as the length of the lower connection part 15. Therefore, any part of the sealers 67 and 68 may be in contact with each other, and the other part may be bent to be in contact with the lower connection part 15.

As a result, the sealers 67 and 68 may shield the connection part through-hole 63 to minimize the inflow of foreign air or foreign matter into the window frame frame 40. In addition, the sealers 67 and 68 may minimize heat loss caused by a gap between the lower connection part 15 and the connection part passing hole 63.

The intermediate frame 13 can be slid relative to the stationary frame 11, and the movable frame 12 can be slid relative to the intermediate frame 13. That is, since the intermediate frame 13 is provided, the total length of the telescopic device 10 required to slide the same distance may be reduced, or the longer distance may be slidable in the telescopic device 10 of the same length.

Meanwhile, a structure such as a lock or detent may be provided between the frames 11, 12, and 13, thereby moving the moving frame 12 and the intermediate frame 13 from the fixed frame 11. Departure in the longitudinal direction can be prevented.

The upper portion of the window 50 is moved near the insertion part through-hole 63. In this case, the elastic member 81 may be provided in a compressed state so that the entire length of the upper connection part 80 may be short. At this time, the opposite end of the portion connected to the push rod 82 in the insertion portion 83 may be moved in contact with the cover portion 61 of the cap 60. That is, the elastic member 81 may provide an elastic force in the direction in which the elastic member 81 is compressed and stretched between the window 50 and the cover portion 61.

When the end portion of the insertion portion 83 reaches the connection portion passage hole 63, the elastic member 81 is extended and the insertion portion 83 may be inserted into the connection portion passage hole 53. In this way, the upper connection part 80 may be coupled to the window frame frame 40.

Even though the free space between the window 50 and the window frame 40 is small by the elastic member 81 of the upper connection portion 80, the upper connection portion 80 can be easily mounted to the window frame frame 40. have. In addition, even when the installation is completed because less initial free space is required, the distance between the window sill 50 and the window frame frame 40 may be reduced as a result. This has the advantage that the heat loss due to the gap between the window 50 and the window frame frame 40 can be reduced. In addition, since the gap between the window 50 and the window frame frame 40 is reduced, the sound insulation effect can also be improved.
