Description

Technical Field

[0001] The utility model relates to an outward-opening window, belonging to the technical field of doors and windows. Background Art

[0002] Most windows can be divided into casement windows, sliding windows, hanging windows, vertical swing windows, and fixed windows according to the opening method. These windows have their own advantages as well as disadvantages. Among them, outward-opening windows can effectively reduce the space occupied by windows, but because the window sash opens outward, people need to lean out to open the window, which may cause the risk of falling, and there is also the risk of children climbing out of the window and falling. According to a Chinese utility model patent (application number: 202121423722.X), a rainproof outward-opening window is disclosed, including a window frame, a window sash and glass. One side frame edge of the window sash is rotatably connected to the window frame, and the other side frame edge of the window sash can be rotated outward to achieve opening. A rain shield that can be freely unfolded and rolled up is provided at the upper frame of the window frame and the window sash. When the rain shield is unfolded, the inner edge of the rain shield is located at the upper frame of the window frame, and the outer edge of the rain shield is located at the upper frame of the window sash. The rain shield surface at the upper end of the rain shield is a diversion slope inclined toward the outside of the window sash. The rainproof outward-opening window is provided with a rain shield between the window sash and the window frame, which can prevent rainwater from entering the room through the window. At the same time, the rain shield has a diversion surface inclined outward, which can discharge the accumulated water on the rain shield in time.

[0003] However, the above device still has the following problems: the above outward-opening window requires a person to lean out to open the window, which may cause the risk of falling, and there is also the risk of children climbing out the window and falling.

[0004] The utility model proposes a new solution to the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0026] like Figure 1-Figure 6 As shown, the outward-opening window provided in this embodiment includes a window frame 1, a window sash 2 rotatably installed on the inner side of the window frame 1 through a hinge, and a lock handle 3 installed on the front side of the window sash 2, a plurality of arc-shaped slide rails 4 located at the bottom of the window sash 2 are fixedly connected to the back of the window frame 1, a rotating shaft 5 is rotatably installed through the top of the window frame 1, a plurality of cloth rolls 6 are fixedly connected to the outer side of the rotating shaft 5, one end of the cloth roll 6 is fixedly installed on the side wall of the window sash 2, and a plurality of springs 7 are fixedly connected between the rotating shaft 5 and the window frame 1.

[0027] By setting the window frame 1, the window sash 2 and the lock handle 3, the window sash 2 can be closed and opened. By setting the arc-shaped slide rail 4, the distance between the two arc-shaped slide rails 4 is small. When a person climbs through the window, even if he steps on empty space, he will not fall. By setting the rotating shaft 5, the cloth roll 6 and the spring 7, when the window sash 2 is opened, the window sash 2 can pull the cloth roll 6 to form a shield between the window frame 1 and the window sash 2 to prevent people from falling from the side. Due to the setting of the spring 7, the cloth roll 6 can be automatically tensioned, and when the window sash 2 is closed, the cloth roll 6 automatically retracts, which is convenient and safe to use.

[0028] In this embodiment, if Figure 2 , Figure 4 and Figure 6As shown, a mounting groove 101 cooperating with the cloth roll 6 is provided on the inner side of the window frame 1, and a rotating groove 102 cooperating with the rotating shaft 5 is provided at the upper and lower ends of the mounting groove 101, and a countersunk groove 103 coaxial with the rotating groove 102 is provided at the upper and lower ends of the window frame 1, and a mounting cap 501 located on the inner side of the countersunk groove 103 is threadedly connected at the upper and lower ends of the rotating shaft 5.

[0029] The installation groove 101 is provided for storing the cloth roll 6, the rotating groove 102 is provided for cooperating with the rotation of the rotating shaft 5, the countersunk groove 103 is provided for limiting the rotating shaft 5 using the installation cap 501, and the installation cap 501 is installed in the countersunk groove 103 and will not interfere with the opening and closing of the window sash 2.

[0030] In this embodiment, if Figure 1 , Figure 3 and Figure 5 As shown, one end of the cloth roll 6 is fixedly connected to a sleeve 601, a plurality of sliding posts 201 cooperating with the sleeve 601 are fixedly connected to the side wall of the window sash 2, a nut 202 is threadedly connected to the top of the sliding post 201, and a limit frame 203 cooperating with the arc-shaped slide rail 4 is fixedly connected to the bottom of the window sash 2.

[0031] The sleeve 601 and the slide post 201 are arranged to fix one end of the cloth roll 6, which is locked with the nut 202. The limit frame 203 cooperates with the arc-shaped slide rail 4 to play a supporting role, preventing people from stepping on the arc-shaped slide rail 4 and bending it to cause danger.

[0032] In this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, a plurality of through holes 104 cooperating with the cloth roll 6 are formed through the back of the installation slot 101 , a rotating column 105 is fixedly installed inside the through hole 104 , and a rotating sleeve 106 is rotatably installed outside the rotating column 105 .

[0033] Through the arrangement of the through hole 104, the rotating column 105 and the rotating sleeve 106, when the cloth roll 6 is extended or retracted, the rotating sleeve 106 will rub against the rotating column 105 to rotate around the rotating column 105, thereby reducing the wear of the cloth roll 6 and increasing the service life.

[0034] In this embodiment, if Figure 1 , Figure 2 and Figure 6 As shown, the cloth roll 6 is a non-woven cloth roll lined with steel wire.

[0035] By setting the cloth roll 6 as a non-woven cloth roll lined with steel wire, the cloth roll 6 has a higher strength and is prevented from breaking. At the same time, the non-woven fabric material is moisture-proof, waterproof and fire-proof, and is safer and more reliable.

[0036] In this embodiment, if Figure 1-Figure 6 As shown, the working process of an outward-opening window provided in this embodiment is as follows:

[0037] Step 1: Unscrew the lock handle 3 and push the window sash 2 away from the window frame 1. At this time, the window sash 2 drives the sleeve 601 to pull out the cloth roll 6, and the cloth roll 6 drives the rotating shaft 5 to rotate, thereby tightening the spring 7. Due to the large friction between the window sash 2 and the arc-shaped slide rail 4, the window sash 2 will stop at a suitable position;

[0038] Step 2: When the window needs to be closed, pull the lock handle 3 and pull the window sash 2 to fit the window frame 1. At this time, under the action of the spring 7, the shaft 5 reverses and retracts the pulled-out cloth roll 6 into the installation groove 101, and the lock handle 3 is turned to lock the window sash 2.

[0039] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
