Description

The present application claims priority from Prior Application CN201410300153.8 filed June 30th, 2014 before the SIPO, entitled "a door or window".

TECHNICAL FIELD OF THE INVENTION

The present invention relates to building doors or windows technical field, particularly to a door or a window.

TECHNICAL BACKGROUND OF THE INVENTION

For the existing doors or windows, in particular swinging doors or swinging windows, there is always a certain distance between the lower part of the door leaf and the floor or between the lower part of the window leaf and the windowsill, to ensure the door or window can be opened and closed without being blocked. However, a gap between the door leaf and the floor or between the window leaf and the windowsill is left as a result, which will result in poor sealing performance, and make it easy for the outdoor materials (such as sand, moisture, insects and the like) entering into the room. In order to solve the problem of sealing the swinging door or the swinging window tightly, those skilled in the art provides the following solutions:
The application entitled as "An automatic adjusting swinging art door" with the Publication Number CN201972566U records as below: the invention discloses an automatic adjusting swinging art door, comprising a door leaf, the bottom of the door leaf is provided with a shell; the shell is of symmetrical structure, and provided with a groove at the center of the shell; both sides of the shell are provided with a sliding groove; two ends of a U-shaped adjusting strip are respectively mounted in the sliding grooves; two adjusting hooks are respectively mounted onto both ends of the U-shaped adjusting strip, and the adjusting hooks are matched up with shell hooks at the bottom of the side wall of the shell, the shell hooks is provided inside the shell and outside the sealing strip groove; and the bottom of the U-shaped adjusting strip is provided with two sealing strips mounted inside the sealing strip groove, the bottoms of the sealing strips extend beyond the sealing strip groove.
That is to say, in the prior art, as the bottom of the door leaf is provided with a shell, and the shell is provided with a sliding groove, U-shaped adjusting strips and adjusting hooks, thus the distance between the door and the floor can be adjusted by utilizing the automatic sealing of the U-shaped adjusting strip and the structure of the adjusting hook. But this relies on the shell structure mounted at the bottom of the door leaf, and the adjusting strips and the adjusting hooks are easy to failure, resulting a short service life. Meanwhile, when the door leaf is opened or closed, the door leaf can be automatically adjusted up and down, thus the adjusting hook will hinder the opening and closing of the door leaf and impact the smooth opening and closing.
GB 440 060 A relates to draught-excluders for doors and windows, it discloses a swinging door which is hinged on the right hand and shuts against door jambs, which are rebated to form recesses; a strip or batten is the draught excluder at the bottom of the door, free to move in a vertical direction and attached to the door by screws which fit freely in slots; when the door is nearly closed, metal fittings A near the extremities of the strip are arranged to slide on bevelled surfaces, and to force the said strip to descend to the floor level to close the space below the door; an angular or rebated member is fitted upon outer doors as a protection when exposed to rain; when the door is nearly closed, one of the fittings being bevelled slides below a bevelled projection, causing said fitting upon the strips to be depressed until a rubber beading is in contact with the floor. However, the prior art cannot adjust the heights of the left and the right of the door leaf or the window leaf respectively.
Furthermore, as the floor or the windowsill is subjected to be of different heights from left to right, the floor or the windowsill is usually not as flat as it is supposed. And this fact requires even higher sealing performance of the swinging door or window. However, in the existing solutions, the sealing performance is obtained according to the highest point of the floor or the windowsill, there is no solution aiming to adjust the heights of the left and the right of the door leaf or the window leaf respectively, therefore the technical problem of complete sealing cannot be solved.
