Inward-turning window

Abstract

The present application relates to an inward-folding window, comprising a fixed window, a movable glass, and an elastic member. A rotating body is provided on the movable glass, and the rotating body rotates in conjunction with the fixed window, allowing the movable glass to open and close in the window. The elastic member abuts between the rotating body and the fixed window. When the movable glass is in the open state, the line connecting the two force points of the elastic member is the end action line. At this time, the force provided by the elastic member to the movable glass causes it to continue rotating in the opening direction. When the movable glass is in the closed state, the line connecting the two force points of the elastic member is the initial action line, and the surface passing through the force point on the elastic member that acts on the fixed window and is parallel to the movable glass in the closed state is the first reference surface. The angle between the initial action line and the first reference surface is less than 13°. This ensures that the elastic member occupies less space in the thickness direction of the movable glass, reducing the overall thickness of the inward-folding window.

Description

Technical Field

[0001] The present application relates to the technical field of vehicle glass, and in particular to an inward-folding window. Background Art

[0002] An inward-tilting window primarily consists of a movable glass and a fixed member. The movable glass can be tilted inward relative to the fixed glass to open the window. The fixed member can be the fixed glass, a vehicle body sheet metal, or a window frame. An elastic member is positioned between the movable glass and the fixed member to provide a spring force to the movable glass, ensuring that the movable glass, once rotated to the open position, tends to remain in that position. The elastic member is typically mounted on the inner side of the pivotable connection between the movable glass and the fixed member. When the movable glass is in the open position, the elastic force provided by the elastic member must have at least an outward component along the thickness of the movable glass. This results in the elastic member being larger in the thickness direction of the movable glass, and thus, the inward-tilting window being larger in that direction. Summary of the Invention

[0003] Based on this, it is necessary to provide an inward-folding window to address the problem of large thickness. By limiting the angle between the initial action line and the first reference plane to less than 13°, the elastic part occupies less space in the thickness direction of the movable glass, thereby reducing the overall thickness of the inward-folding window.

[0004] An inward-turning window, comprising:

[0005] A fixed window having a window;

[0006] A movable glass, wherein a rotating body is provided on the movable glass, and the rotating body rotates in conjunction with the fixed window body, so that the movable glass can be opened and closed at the window;

[0007] an elastic member, the elastic member abutting between the rotating body and the fixed window;

[0008] When the movable glass is in the open state, the line connecting the two force points of the elastic member is the end action line. At this time, the force provided by the elastic member to the movable glass has a tendency to continue rotating in the opening direction.

[0009] When the movable glass is in the closed state, the line connecting the two force points of the elastic member is the initial action line, and the surface passing through the force points on the elastic member acting on the fixed window and parallel to the movable glass in the closed state is the first reference surface;

[0010] An angle between the initial action line and the first reference surface is less than 13°.

[0011] The above solution provides an inward-tilting window in which a movable glass can rotate relative to a fixed window body to control the opening and closing of the window. When the movable glass rotates to the open position, an elastic member acting between a rotating body and the fixed window body provides a force on the movable glass, causing it to continue rotating in the opening direction, thereby maintaining the movable glass in the open position. As the movable glass rotates, the rotating body follows, causing the position on the elastic member acting on the rotating body to move synchronously. By limiting the angle between the initial line of action and the first reference plane to less than 13°, the elastic member occupies less space in the thickness direction of the movable glass, thereby reducing the overall thickness of the inward-tilting window.

[0018] The inward-folding window also includes a buffer assembly, which is arranged between the side rod and the frame. A mounting groove is provided on the surface of the side rod facing the frame. The buffer assembly is at least partially installed in the mounting groove. The buffer assembly can play a buffering role when the movable glass rotates from the open state to the closed state.

[0040] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0041] like Figure 1 and Figure 2 As shown, the inward-folding window 10 includes a fixed window 11, a movable glass 12, and an elastic member 13. The fixed window 11 is provided with a window 112. The movable glass 12 is provided with a rotating body 15, which rotates in conjunction with the fixed window 11, allowing the movable glass 12 to open and close within the window 112. When the movable glass 12 rotates relative to the fixed window 11, the rotating body 15 rotates synchronously with the fixed window 11. The elastic member 13 abuts between the rotating body 15 and the fixed window 11. During the rotation of the rotating body 15, the elastic member 13 moves synchronously with the rotating body 15. Specifically, during the rotation of the rotating body 15, the elastic member 13 will rotate macroscopically around the position where it abuts the fixed window 11, and the relative position of the portion of the elastic member 13 abutting the rotating body 15 and the fixed window 11 will change.

[0042] The main function of the elastic member 13 is as follows Figure 4 As shown, when the movable glass 12 rotates to the open state, it can provide a pushing force for the rotating body 15, so that the rotating body 15 has a tendency to continue rotating in the opening direction, thereby allowing the movable glass 12 to remain in the open state.

[0043] like Figure 4As shown, when the movable glass 12 is in the open position, the elastic member 13 provides an upward thrust to the rotating body 15. This thrust can be decomposed into a force component toward the outside of the fixed window 11, thereby causing the rotating body 15 to continue to rotate clockwise. When the movable glass 12 is in the open position, one side is on the inside of the fixed window 11, and the other side is on the outside of the fixed window 11.

[0044] The opening direction of the movable glass 12 in this application refers to the rotation direction of the movable glass 12 when switching from the closed state to the open state, for example, Figures 1 to 3 The opening direction of the movable glass 12 is clockwise from the viewing angle shown. Correspondingly, the closing direction of the movable glass 12 is the direction of rotation when the movable glass 12 switches from the open state to the closed state. Figures 1 to 3 The closing direction of the movable glass 12 in the illustrated viewing angle is counterclockwise.

[0045] Related technologies such as Figure 11 and Figure 12 As shown, when the movable glass 12 is in the closed state, the elastic member 13 is arranged roughly along the thickness direction of the movable glass 12, and the direction of the pushing force of the elastic member 13 is roughly along the thickness direction of the movable glass 12. The angle between the direction of the pushing force provided by the elastic member 13 and the thickness direction of the movable glass 12 is small, so the elastic member 13 occupies a large space in the thickness direction of the movable glass 12, resulting in the problem of a large thickness of the inward-folding window 10.

[0046] Based on this, in certain embodiments of the present application, a window 10 is provided, such as Figures 1 to 5 As shown, when the movable glass 12 is in the open state, the line connecting the two force points of the elastic member 13 is the end action line 131. At this time, the force provided by the elastic member 13 to the movable glass 12 makes it have a tendency to continue rotating in the opening direction.

[0047] When the movable glass 12 is in the closed state, the line connecting the two force points of the elastic member 13 is the initial action line 132. The surface passing through the force points on the elastic member 13 that act on the fixed window 11 and parallel to the movable glass 12 in the closed state is the first reference surface 133.

[0048] The angle between the termination action line 131 and the first reference surface 133 is greater than the angle between the initial action line 132 and the first reference surface 133, and the angle between the initial action line 132 and the first reference surface 133 is less than 13°. Figure 3As shown, the angle between the initial action line 132 and the first reference plane 133 is 0°. In other words, the initial action line 132 is located on the first reference plane 133. In this case, the space occupied by the elastic member 13 in the thickness direction of the movable glass 12 is negligible, and the overall thickness L of the inward-tilting window 10 is relatively small.

[0049] In some embodiments, the initial action line 132 and the first reference surface 133 may also be arranged at a smaller angle. Preferably, the angle between the two is within 10°.

[0050] In one embodiment, Figure 3 As shown, the thickness L of the inward-folding window 10 is 29 mm.

[0051] When the angle between the initial action line 132 and the first reference plane 133 is greater than 0°, the terminal action line 131 and the initial action line 132 are located on the same side of the first reference plane 133, and the angle between the terminal action line 131 and the first reference plane 133 is greater than the angle between the initial action line 132 and the first reference plane 133. By limiting the angle between the initial action line 132 and the first reference plane 133 to less than 13°, the elastic member 13 occupies less space in the thickness direction of the movable glass 12, thereby reducing the overall thickness of the inward-tilting window 10. Although the angle between the elastic member 13 and the first reference plane 133 increases when the movable glass 12 is switched to the open state, and the space occupied by the elastic member 13 in the thickness direction of the movable glass 12 increases, the space occupied by the elastic member 13 is significantly reduced compared to a case where the elastic member 13 is disposed substantially along the thickness direction of the movable glass 12.

[0052] In some usage scenarios, such as Figure 3 and Figure 4 As shown, the fixed window 11 is arranged in the longitudinal direction, and the first reference surface 133 is a longitudinal plane passing through the force point on the elastic member 13 that acts on the fixed window 11 .

[0053] Furthermore, if Figure 3 and Figure 4As shown, in some embodiments, the rotating body 15 is hinged to the fixed window 11, and the axis of the hinge is a first axis. The point of application on the elastic member 13 corresponding to the fixed window 11 is a fixed application point 135, and the point of application on the elastic member 13 corresponding to the rotating body 15 is a movable application point 136. When the movable glass 12 is in the closed state, the line connecting the fixed application point 135 and the movable application point 136 is an initial action line 132. When the movable glass 12 is in the open state, the line connecting the fixed application point 135 and the movable application point 136 is a terminal action line 131. The plane passing through the fixed application point 135 and the first axis is a second reference plane 134, and the initial action line 132 and the terminal action line 131 are respectively located on opposite sides of the second reference plane 134.

[0054] like Figure 3 As shown, when the movable glass 12 is in the closed state, the initial action line 132 is located on the right side of the second reference surface 134. Figure 4 As shown, when the movable glass 12 is in the open position, the end action line 131 is located to the left of the second reference plane 134. The compression of the elastic member 13 reaches its maximum when the line connecting the fixed action point 135 and the movable action point 136 is located on the second reference plane 134. However, the movable glass 12 is only in this position for a moment during its movement. Long-term positions such as the open and closed states experience less compression, extending the service life of the elastic member 13.

[0055] like Figure 4 As shown, the movable glass 12 in the open state rotates at an angle a1 of no greater than 32° relative to the closed state, and the angle between the end-action line 131 and the first reference plane 133 is no greater than 45°. In one embodiment, the angle between the initial action line 132 and the first reference plane 133 is 0°, the movable glass 12 in the open state rotates at an angle of 30° relative to the closed state, and the angle between the end-action line 131 and the first reference plane 133 is also 30°.

[0056] More specifically, in one embodiment, Figure 3 and Figure 4 As shown, the angle between the initial action line 132 and the second reference surface 134 is equal to the angle between the terminal action line 131 and the second reference surface 134 .

[0057] The length of the initial action line 132 is equal to the length of the terminal action line 131. The amount of compression of the elastic member 13 when the movable glass 12 is in the closed state is the same as the amount of compression when the movable glass 12 is in the open state. This effectively prevents the elastic member 13 from being excessively compressed when the movable glass 12 is in the open state, thereby preventing it from failing to recover its elasticity after prolonged use. This improves the durability of the elastic member 13. In one embodiment, the deformation of the elastic member 13 when the movable glass 12 is in the closed state and when the movable glass 12 is in the open state is zero, thereby significantly extending the service life of the elastic member 13.

[0058] Furthermore, in one embodiment, the angle between the initial action line 132 and the second reference surface 134 is 15°, and the angle between the termination action line 131 and the second reference surface 134 is also 15°.

[0059] The elastic member 13 may be an S-shaped spring or other elastic device, as long as it can provide a pushing force for the rotating body 15 so that the rotating body 15 has a tendency to continue rotating in the opening direction when the movable glass 12 is in the open state.

[0060] Specifically, in some embodiments, Figure 6 As shown, the elastic member 13 is an S-shaped spring. The S-shaped spring is an elastic member bent into an S shape, with the two distal ends of the S-shaped spring spaced apart, and the spacing direction of the two distal ends is consistent with the direction in which the S-shaped spring can be compressed and deformed.

[0061] Each distal end of the S-shaped spring has an abutment section 137, with the two abutment sections 137 arranged parallel and spaced apart. The spacing between the two abutment sections 137 is parallel to the direction of the S-shaped spring's compressible deformation. The end action line 131 and the initial action line 132 are both parallel to the spacing between the two abutment sections 137 of the S-shaped spring in the corresponding state. A rotatable sleeve 14 is sleeved over each abutment section 137. The S-shaped spring is pressed between the rotating body 15 and the fixed window 11, and the two sleeves 14 abut against the rotating body 15 and the fixed window 11, respectively.

[0062] As the S-shaped spring rotates with the rotating body 15, it does not directly contact either the rotating body 15 or the fixed window 11. Instead, the abutment section 137 of the S-shaped spring rotates within the sleeve 14. Since the rotating body 15 and the fixed window 11 are typically made of aluminum, the S-shaped spring has a high coefficient of friction with aluminum. However, since the sleeve 14 can be made of a copper tube, the coefficient of friction between the S-shaped spring and the copper tube is relatively low. Therefore, the installation of the sleeve 14 reduces frictional resistance during rotation of the S-shaped spring, resulting in less noise.

[0063] Furthermore, the diameter of the abutment section 137 is smaller than the inner diameter of the sleeve 14, allowing a certain amount of free play within the sleeve 14, allowing the abutment section 137 to move slightly radially relative to the sleeve 14. Since both ends of the S-shaped spring are sleeved with the sleeve 14, when the rotating body 15 rotates, both ends of the S-shaped spring can swing within the sleeve 14 if necessary. The two abutment sections 137 of the S-shaped spring experience sliding friction with the outside world, making rotation smoother. When rotation stops, the S-shaped spring can be adjusted to an optimal state, in which it is only subjected to forces along the direction separating the two abutment sections 137, with essentially no forces in other directions. Therefore, the S-shaped spring is only subjected to compression, not torque.

[0064] When the movable glass 12 is in the open state, the line connecting two points located on the axes of the two abutting sections 137 and with the smallest distance between them is the end action line 131 , and the length of the end action line 131 is the distance between the two abutting sections 137 .

[0065] When the movable glass 12 is in the closed state, the line connecting two points located on the axes of the two abutting sections 137 with the smallest distance between them is the initial action line 132 , and the length of the terminal action line 131 is the distance between the two abutting sections 137 .

[0066] Furthermore, if Figure 1 and Figure 2 As shown, in some embodiments, the fixed window body 11 includes a fixed glass 111 and an outer frame (not shown in the figure), the outer frame is arranged around the fixed glass 111, and the window 112 is provided with an inner frame 113. The rotating body 15 is rotatably connected to the inner frame 113, the elastic member 13 abuts between the rotating body 15 and the inner frame 113, and an anti-drop connection member 16 is provided between the inner frame 113 and the outer frame.

[0067] It can be understood that the movable glass 12 and the rotating body 15 are both installed on the inner frame 113, and the inner frame 113 is directly connected to the outer frame through the anti-fall connection member 16. Therefore, even if the fixed glass 111 is broken, the movable glass 12, the rotating body 15 and the elastic member 13 will not fall off.

[0068] Specifically, if Figure 2 As shown, in one embodiment, a plurality of anti-drop connectors 16 are provided between the inner frame 113 and the outer frame. The inner frame 113 is a polygonal frame, and each side of the inner frame 113 is provided with an anti-drop connector 16 to the outer frame.

[0069] Furthermore, if Figure 1 and Figure 2As shown, in some embodiments, the movable glass 12 is provided with a frame 121 around its periphery, and the rotating body 15 is connected to the frame 121. When the movable glass 12 is closed, the frame 121 is located within the space enclosed by the inner frame 113. The inner frame 113 is a polygonal frame and has two side rods 1131. The lengths of the two side rods 1131 intersect the axial direction along which the rotating body 15 can rotate relative to the inner frame 113.

[0070] The inward-folding window 10 also includes a buffer component 17, which is arranged between the side rod 1131 and the frame 121. When the movable glass 12 rotates from the open state to the closed state, the buffer component 17 can play a buffering role to prevent the movable glass 12 from closing quickly and causing pinching.

[0071] like Figure 3 As shown, when the movable glass 12 rotates to a certain position in the closing direction, the elastic member 13 provides a force for the rotating body 15 to rotate in the closing direction. If there is no other force blocking it, the movable glass 12 will close faster under the action of the elastic member 13. After the buffer assembly 17 is provided, the rotation speed of the movable glass 12 will be slowed down when it approaches the closed position, thereby reducing the risk of pinching.

[0072] Furthermore, if Figure 2 and Figure 7 As shown, the side bars 1131 are provided with mounting grooves 1132 on the surfaces facing the frame 121. The buffer assembly 17 is at least partially mounted in the mounting grooves 1132. The buffer assembly 17 is located to the side of the movable glass 12 and can be partially housed within the inner frame 113, resulting in a neater appearance. Furthermore, a buffer assembly 17 can be positioned between each of the side bars 1131 and the frame 121.

[0073] The buffer component 17 may be a damper, a buffer pad or other devices with buffering capabilities.

[0074] Specifically, if Figure 8 and Figure 9 As shown, in one embodiment, the buffer assembly 17 includes a connecting rod 171, a slider 172 and a buffer 173. One end of the connecting rod 171 is hinged to the frame 121, and the other end of the connecting rod 171 is hinged to the slider 172. Figure 2 and Figure 7As shown, the side rod 1131 is provided with a slide groove 1133. The guide direction of the slide groove 1133 is consistent with the length direction of the side rod 1131. The slider 172 is slidably disposed in the slide groove 1133. The buffer 173 is installed in the installation groove 1132. When the movable glass 12 rotates from the open state to the closed state, the slider 172 slides toward the buffer 173 and can abut against the buffer 173. The buffer 173 is used to provide a force to slow down the slider 172 from continuing to slide.

[0075] When the movable glass 12 rotates to a certain extent in the closing direction, the slider 172 slides to contact the buffer 173, and the buffer 173 provides a reverse force for the slider 172, so that the sliding speed of the slider 172 along the sliding groove 1133 is reduced, and the movable glass 12 slowly closes.

[0076] like Figure 2 and Figure 7 As shown, the slide groove 1133 is connected to the installation groove 1132 , and the portion of the buffer 173 for contacting the slider 172 is located in the sliding direction of the slide groove 1133 , and the slider 172 can slide along the slide groove 1133 until it contacts the buffer 173 .

[0077] Furthermore, if Figure 2 As shown, in some embodiments, the inner frame 113 is welded with two blocking pieces 114 , and when the movable glass 12 is in the closed state, both end surfaces of the rotating body 15 face the two blocking pieces 114 respectively.

[0078] When the movable glass 12 is in the closed state, the two blocking pieces 114 can cover the two ends of the rotating body 15. When the rotating body 15 rotates, there may be sliding friction between the blocking pieces 114 and the inner frame 113. The blocking pieces 114 are welded to the inner frame 113 and the connection between the two is firm, which greatly reduces the probability of the blocking pieces 114 falling off as the rotating body 15 moves.

[0079] like Figures 3 to 5 As shown, in some embodiments, the inner frame 113 has a frame support portion 1134, which is connected to the fixed glass 111. The frame support portion 1134 has a fixed limit position 1135 for the elastic member 13 to abut. The inner frame 113 also has a fixed shaft 1136 for hinged connection with the rotating body 15, and the fixed shaft 1136 is connected to the frame support portion 1134. The elastic member 13 abuts between the frame support portion 1134 and the rotating body 15. In some embodiments, the inner frame 113 is a rectangular frame, and the frame support portion 1134 is one side of the rectangular frame.

[0080] Furthermore, if Figures 3 to 5As shown, the rotating body 15 includes an arcuate member 151 that partially surrounds the fixed shaft 1136. The term "half-enclosed" does not simply mean "enclosed halfway," but rather refers to the fact that the distal ends of the arcuate member 151 are spaced apart and do not completely surround the fixed shaft 1136 in the axial direction. In the direction of its curvature, the distal ends of the arcuate member 151 are respectively used to connect with the movable glass 12 and abut against the elastic member 13.

[0081] When the rotating body 15 rotates, the portion of the elastic member 13 that acts on the rotating body 15 rotates along with the rotating body 15. The active point of action 136 moves on an arc path with the axis of the fixed shaft 1136 as the center.

[0082] like Figures 3 to 5 ,as well as Figure 10 As shown, in some embodiments, the fixed shaft 1136 is provided with a notch 1137. The arc of the outer circumference of the fixed shaft 1136 in a cross-section of the fixed shaft 1136 is a major arc. The central angle of the arc-shaped member 151 is greater than 180°. When the movable glass 12 is in the open state, the rotating body 15 is in the open position. The rotating body 15 can continue to rotate relative to the fixed shaft 1136 in the opening direction to the removal position. In the removal position, the arc-shaped member 151 can be removed from the fixed shaft 1136 in a direction perpendicular to the axis. The axis here refers to the axis of the fixed shaft 1136.

[0083] like Figure 3 and Figure 4 As shown, before the rotating body 15 rotates relative to the fixed shaft 1136 to the disassembly position, the arc-shaped member 151 can surround the fixed shaft 1136 and will not fall off, as the central angle of the arc-shaped member 151 is greater than 180°. Figure 5 and Figure 10 As shown, since the outer circumference of the fixed shaft 1136 forms a major arc in cross section rather than a closed circle, the arc-shaped member 151 can rotate relative to the fixed shaft 1136 to a position where the arc-shaped member 151 can move relative to the fixed shaft 1136 in a direction perpendicular to the axis, so that the fixed shaft 1136 can be removed from the opening of the arc-shaped member 151. The axis here refers to the axis of the fixed shaft 1136.

[0084] like Figure 10 As shown, the line connecting the two end points of the arc-shaped member 151 is line L1. When the rotating body 15 rotates to the disassembly position, the rotating body 15 moves in a direction perpendicular to the axis relative to the fixed shaft 1136. During the movement, the arc-shaped member 151 can move radially relative to the fixed shaft 1136 while rotating slightly until the rotating body 15 is removed from the fixed shaft 1136.

[0085] It should be noted that the size of the notch 1137 needs to meet the requirement that the arc-shaped member 151 can be removed from the fixed shaft 1136. Figure 10 As shown, the cross section of the notch 1137 is surrounded by a chord S1 and an arc M1 (not shown in the figure), the center of the circle corresponding to the arc M1 is the center O1, the arc M1 is a minor arc, the distance from the chord S1 to the center O1 is N1, and the sum of N1 and the radius R1 is less than the length of the line H1.

[0086] In another embodiment, Figures 3 to 5 As shown, the cross section of the notch 1137 is fan-shaped, and the arc-shaped member 151 in the disassembly position can continue to adjust so that one end of itself rotates into the notch 1137, and then continuously adjust and move so that the arc-shaped member 151 is removed from the fixed shaft 1136. Figure 5 As shown, the central angle of the sector presented by the cross section of the notch 1137 is 90°, and the central angle corresponding to the opening of the arc-shaped member 151 is greater than 90°. The rotating body 15 can be removed from the fixed shaft 1136 after rotating a preset angle in the opening direction starting from the closed state of the movable glass 12. The preset angle here is not less than 110°.

[0087] Furthermore, if Figures 3 to 5 As shown, in one embodiment, the inward-folding window 10 further includes a decorative member 18, which is detachably connected to the inner frame 113. Specifically, the decorative member 18 can be detachably connected to the frame support portion 1134. The decorative member 18 is concealed on the side of the elastic member 13 facing away from the fixed window 11. The arc-shaped member 151 is located between the decorative member 18 and the fixed shaft 1136. When the movable glass 12 is in the open position, the rotating body 15 abuts against the decorative member 18, providing a force that prevents the rotating body 15 from continuing to rotate in the opening direction.

[0088] The decorative member 18 not only shields the elastic member 13 and part of the internal structure of the inner frame 113, but also ensures that the rotating body 15 is in the open state of the movable glass 12 to a certain extent during the normal opening and closing of the window. Figures 3 to 5 As shown, the frame support portion 1134 has a blocking slope 1138. When the movable glass 12 is in the open state, the elastic member 13 is parallel to and abuts against the blocking slope 1138, and the termination line of action 131 is parallel to the blocking slope 1138. At this time, the blocking slope 1138 can prevent the elastic member 13 from continuing to rotate.

[0089] In the process of disassembling the movable glass 12, as shown in FIG. Figure 5As shown, the decorative member 18 can be removed from the inner frame 113 first, and then the elastic member 13 can be removed. Then, the movable glass 12 and the rotating body 15 can be rotated until the rotating body 15 can fall off the fixed shaft 1136.

[0090] like Figure 1 and Figure 2 As shown, in some embodiments, the inward-turning window 10 further includes a window lock 19, which is disposed inside the movable glass 12 and / or the fixed glass 111 and is used to lock the closed movable glass 12 with the fixed glass 111, thereby improving safety and ensuring that the movable glass 12 is opened only when needed. The movable glass 12 can only be opened after the window lock 19 is unlocked.
