Abstract

The doors and windows with a two-way opening structure are composed of a window frame, a door and window sash and two rotating handles. Four shaft seats are installed on the corners, and the four retractable shafts can be connected with the four shaft seats on the door and window frame, controlled by a rotating handle, which can be inserted into the holes of the shaft seat at the same time to form the rotating shaft of the door and window, or at the same time. Separated from the axle base, the sash can be opened from the left or from the right. If the handle on the left is rotated, the sash can be opened to the right, and if the handle on the right is rotated, the sash can be opened to the left. When it is necessary to clean the glass, it is easy to wipe the front and back sides of the window sash.

Description

Doors and windows with two-way opening structure

technical field

The invention relates to a two-way opening door and window structure, in particular to a door and window that can be freely opened left and right.

Background technique

Nowadays, the doors and windows of houses are more commonly opened from the inside to the outside, from the outside to the inside, or by pushing and pulling left and right. Window removed to replace glass.

SUMMARY OF THE INVENTION

We propose to install four retractable shafts on the front or back of the window sash, and install four shaft seats on the front or back of the window frame. Good opening, after continuous research and experiments, it is found that the fundamental reason why the window sash cannot be fully opened is that the four shafts installed on the back of the window sash, when the upper and lower shafts on one side are opened, the two shafts at the other end are used as rotating shafts. When the window is turned and opened, the back of the sash and the front of the window frame will form an angle. The actual opening angle should be less than 40 degrees, so that the window cannot be opened normally. window to use.

The purpose of the present invention is to provide a door and window that can be opened at an angle of 180 from left and right, and at the same time, a window that can be removed and cleaned at will, so as to overcome the shortcomings of the existing doors and windows. After a lot of research and experiments, it was finally found that when the upper and lower telescopic shafts on both sides are installed on the two sides of the window sash, the window can be opened at an angle of 180 degrees, which fully meets the conditions for actual use. Install the rotating shaft on the front of the window frame and the back of the window sash. Since these two surfaces are parallel to each other, their opening is limited, and the two sides of the window sash are perpendicular to the front of the window frame, so their axes can be Rotate in the range of 180 degrees, as shown in Figure 8.

The door and window structure with two-way opening is composed of a window frame, a door and window sash and a shaft seat. Four axle seats are installed on the four corners, and the four retractable axles can be connected with the four axle seats on the door and window frame, and the upper and lower two telescopic axles on one side can be controlled by a handle and can be inserted at the same time The hole of the shaft seat forms the rotating shaft of the door and window, and it can also be separated from the shaft seat at the same time, as shown in Figure 1 and Figure 3.

The present invention is specifically implemented in this way, a pair of telescopic shafts are respectively installed on the upper and lower ends of the left and right sides of the door and window sash, and four shaft seats are installed on the four corners of the front of the window frame corresponding to the four telescopic shafts, The left pair of telescopic shafts can simultaneously extend into and out of the holes of the left axle seat, the right pair of telescopic shafts can simultaneously extend into and out of the right axle seat holes, and the left pair of telescopic shafts The shaft is connected with the rotating handle on the left through a rope, and the pair of telescopic shafts on the right are connected with the rotating handle on the right through a rope. Two rotating handles are installed in the middle of the two sides of the front of the window sash. The shaft is in the extended state. At this time, the shaft of the telescopic shaft is stuck in the hole of the shaft seat, which plays the role of fixing the shaft. When the rotating handle on the other side is in the vertical position, the handle can be pulled to open the window sash. The fixed shaft will rotate in the hole of the shaft seat, and it can actually rotate 180 degrees. When the left and right rotating handles are in the horizontal position, the shaft of the telescopic shaft is extended into the hole of the shaft seat, and the window is closed at this time. The structure of the two rotating handles is as follows, the upper telescopic shaft is connected to the upper end of the semicircular rotating plate through a rope, the lower telescopic shaft is connected to the lower end of the semicircular rotating plate through a rope, and the middle of the semicircular rotating plate is fixed. With the rotating handle, the rotating handle is perpendicular to the straight side of the semi-circular rotating plate, and the two are fixed as a whole. The semi-circular rotating plate is connected with the lower semi-circular fixed plate through the bearing. On the window sash, there is an arc groove on the arc edge of the semi-circular rotating plate, so that the rope is not easy to slip out when the semi-circular rotating plate rotates, and there is a small hole at the upper and lower ends of the semi-circular fixed plate. The rope is connected to the telescopic shaft and the semi-circular rotating disc through small holes, as shown in Figure 4 and Figure 5. A circle of Ω-shaped sealing tape is set on the back side of the window sash, or a circle of Ω-shaped sealing tape is set on the front side of the window frame, the effect is the same, as shown in Figure 2 and Figure 3 . The structure of the telescopic shaft is such that when the rope hole of 13 is not stressed, the shaft will extend outward for the longest time under the action of the spring, and the shaft will retreat inward when the 13 hole is pulled by the rope, as shown in Figure 6 . The structure of the axle seat is very simple, which is a ⊥-shaped metal piece with four mounting holes on its vertical plane and a circular hole on its horizontal plane, which is the fixing hole of the axle.

A shaft lock is arranged on the rotating shaft of the handle, and the shaft lock can lock the shaft and make the rotating handle lose its rotation function. The handle can be rotated by inserting the key into the shaft lock hole, and the handle cannot be rotated when the key is pulled out.

Detailed ways

If the omega-shaped sealing strip is installed on the window frame, just rotate the two rotating handles on the window sash to the vertical position, then the shafts of the four telescopic shafts are retracted into the outer casing, lift the window sash and place it on the window frame , align the shafts of the four telescopic shafts with the hole positions of the four shaft seats on the window frame, and then rotate the two rotating handles on the window sash to the horizontal position, at this time, the shafts of the four telescopic shafts pop out to the outer casing In addition, it is stuck in the holes of the four shaft seats of the window frame, and the installation of the window sash is completed. At this time, if you rotate the handle on the left, you can open the sash to the right; if you rotate the handle on the right, you can open the sash to the right. Open to the left.

If the omega-shaped sealing strip is installed on the window sash, the installation of the window sash is the same as the above method. When the glass needs to be cleaned, it is easy to wipe the front and back sides of the window sash.

If the fixed glass is replaced with such windows in practice, then there will be no windows that are difficult to clean. Each window has four fixed points, which should be stronger than the current three-point fixed doors and windows, and Lock the handle with a key for easy management.
