Abstract
Description
Technical Field
[0001] This application relates to the field of door and window fittings technology, specifically to a limiting device for windows. Background Technology
[0002] In daily life, when freely sliding windows are unlocked, they pose a safety hazard to special groups (such as young children). Therefore, it is necessary to install a self-locking structure on the windows to limit their movement and protect people's safety.
[0003] One common type of window design involves installing a stop mechanism, such as a stop bar or a self-locking block. To open the window, tools are needed to remove this stop mechanism. This type of stop mechanism is not conducive to the reciprocating opening and closing of the window.
[0004] Another type of stop structure allows the window to open to a smaller extent, but it's difficult to open it to a larger extent. Yet another type of stop structure is only suitable for doors and is difficult to apply to windows. Utility Model Content
[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a limiting device for windows, which can both restrict small-amplitude opening and closing of windows and allow large-amplitude opening and closing. This limiting device allows for convenient reciprocating opening and closing of windows without the need for tools.
[0006] The limiting device for a window according to this application includes: a base plate for mounting on a first window or a window frame; a limiting member having a connecting end and a limiting end at two ends, the connecting end for connecting to the base plate and the limiting end for engaging with a second window, the second window being movable from the window frame; the base plate having a first side and a second side opposite to each other.
[0007] The limiting device further includes an elastic arm, which connects the first side and the connecting end, and the limiting end and the second side are located on the same side of the elastic arm.
[0008] The elastic arm is a bent sheet metal part, so that the elastic arm can be repeatedly deformed and reset.
[0009] According to the limiting device for windows of this application, when the limiting member is not pressed, the limiting end of the limiting member is locked on one side of the second window, thereby restricting the opening and closing of the second window within a small range and protecting the personal safety of vulnerable groups. When the limiting member is pressed, because the elastic arm is a bent sheet metal part with a large bending range, the limiting member moves closer to the base plate, the entire limiting device becomes thinner, and can be retracted to one side of the second window, at which point it is convenient for the second window to open and close within a large range.
[0010] This limiting device, with its elastic arm, can be used repeatedly without needing to be removed when opening or closing the window, making it very convenient to use.
[0011] In some embodiments, the substrate, the limiting member, and the elastic arm are integral sheet metal parts.
[0012] In some embodiments, the limiting device further includes an anti-slip portion disposed on the limiting end.
[0013] In some embodiments, the anti-slip portion is the edge line of the limiting member at the limiting end, and the edge line is a wavy line.
[0014] In some embodiments, the limiting member includes:
[0015] An extension arm plate, one end of which is the connecting end, wherein the extension arm plate is an arc-shaped plate or a straight plate;
[0016] The pressing arm plate has one end as the limiting end and the other end connected to the other end of the extension arm plate. The pressing arm plate is either an arc-shaped plate or a straight plate.
[0017] In some embodiments, the pressing arm plate is a straight plate, and the pressing arm plate is arranged parallel to the substrate.
[0018] In some embodiments, the limiting device further includes an auxiliary spring arm, the two ends of which are fixed ends and free ends, the fixed ends being connected to the substrate, and the free ends being disposed away from the substrate and extending toward the limiting member.
[0019] In some embodiments, the auxiliary spring arm gradually approaches the connecting end in the direction from the fixed end to the free end.
[0020] In some embodiments, the substrate has a through hole in the middle, the fixed end is connected to the side of the through hole, and the auxiliary spring arm is formed by bending the material of the substrate located at the through hole.
[0021] In some embodiments, the auxiliary elastic arm forms a hook at its free end that bends toward the elastic arm.
[0022] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0042] The limiting device 100 for a window according to an embodiment of the present invention is described below with reference to the accompanying drawings.
[0043] Reference Figures 2-5 The limiting device 100 for windows includes: a base plate 10 and a limiting member 20. For example... Figure 1 As shown, the substrate 10 is used to mount on the first window 200 or the window frame 400. The substrate 10 has a first side 101 and a second side 102 facing each other. The two ends of the limiting member 20 are a connecting end 201 and a limiting end 202, respectively. The connecting end 201 is used to connect the substrate 10, and the limiting end 202 is used to cooperate with the second window 300. The second window 300 and the window frame 400 are movable.
[0044] The limiting device 100 further includes an elastic arm 30, which connects the first side 101 and the connecting end 201. The limiting end 202 and the second side 102 are located on the same side of the elastic arm 30. The elastic arm 30 is a bent sheet metal part, so that the elastic arm 30 can be repeatedly deformed and reset.
[0045] It is understandable that the substrate 10 and the limiting member 20 constitute the second main structure of the limiting device 100. The substrate 10 provides the installation position, and the limiting member 20 is installed on the first window 200 or window frame 400 through the substrate 10, so that the position of the limiting member 20 relative to the first window 200 or window frame 400 is substantially fixed.
[0046] One end of the limiting member 20 is a limiting end 202, which selectively abuts against the second window 300. That is, the second window 300 is movable relative to the first window 200 or the window frame 400. Therefore, in different positions, the limiting end 202 can abut against the second window 300 or detach from the second window 200.
[0047] The elastic arm 30 is also part of the main structure of the limiting device 100. By setting the elastic arm 30 as a curved sheet metal part, the elastic arm 30 can reciprocate and reposition. In this way, the second window 300 can be opened and closed to a large extent.
[0048] It should be noted that the window used for the limiting device 100 may include only the second window 300, or it may include both the first window 200 and the second window 300. The limiting device 100 can be installed on the window frame 400 to limit the opening range of the second window 300, or it can be installed on the first window 200 to limit the opening range of the second window 300. The window structure is not limited here; for ease of description, the following will combine... Figure 1 The solution is illustrated using the example of the limiting device 100 being installed on the first window 200.
[0049] Specifically, with Figure 1 and Figure 2 In the example shown, the substrate 10 is fixed to the upper first window 200, and the limiting member 20 is located above the second window 300. Before the limiting device 100 is pressed... Figure 6 As shown, the limiting device 100 is pressed as follows: Figure 7 As shown.
[0050] When the limiting member 20 is not pressed against the substrate 10, moving the second window 300 upwards will open it. Once the upper end of the second window 300 reaches the limiting end 202 of the limiting member 20, the second window 300 can no longer move upwards. This limits the opening of the second window 300 to a small range, protecting the safety of vulnerable groups (such as young children). Moving the second window 300 downwards at this point will disengage it from the limiting end 202 of the limiting member 20.
[0051] Furthermore, the limiting device 100 can be positioned in a location that is difficult for special groups (such as young children) to find. For example, it can be set high up so that special groups (such as young children) have difficulty touching it. Alternatively, the limiting device 100 can be placed in a hidden location so that special groups (such as young children) cannot notice it.
[0052] When the limiting member 20 is pressed towards the substrate 10, the elastic arm 30, being a bent sheet metal part, is deformed, allowing the limiting member 20 to retract into the gap between the first window 200 and the second window 300. Moving the second window 300 upwards at this time opens it, no longer restricted by the limiting end 202 of the limiting member 20. This allows the second window 300 to open over a wide range, enabling normal people to open it. Moving the second window 300 downwards, when it reaches below the limiting end 202 of the limiting member 20, the elastic arm 30 resets, allowing the limiting end 202 of the limiting member 20 to again restrict the second window 300.
[0053] Of course, the limiting device 100 of this application can be used not only on windows that slide up and down, but also on windows that slide left and right or along other directions.
[0054] The window limiting device 100 according to this application not only restricts the opening and closing of the second window 300 within a small range, protecting the personal safety of vulnerable groups, but also, because the elastic arm 30 is a curved sheet metal part with a large bending range, allows normal users to press the limiting member 20 to avoid the second window 300, facilitating a large range of opening and closing of the second window 300. This limiting device 100, through the structure of the elastic arm 30, can be used reciprocally, and does not need to be removed when opening and closing the window, making it very convenient to use.
[0055] In some embodiments, the substrate 10, the limiting member 20, and the elastic arm 30 are integral sheet metal parts. This single-piece molding process results in high material utilization and low cost. Furthermore, as an integral sheet metal part, when the limiting member 20 is pressed, the limiting device 100 can be pressed very thin, thus making it suitable for a wide range of window types and applications.
[0056] Specifically, the substrate 10, the limiting member 20, and the elastic arm 30 are V-shaped or U-shaped to improve elasticity.
[0057] In some embodiments, such as Figure 2 As shown, the limiting device 100 also includes an anti-slip part 40, which is disposed on the limiting end 202. The anti-slip part 40 serves to limit and prevent slippage, thereby improving the limiting effect on the second window 300 and reducing the possibility of slipping or falling off when the limiting end 202 is in position.
[0058] Specifically, the anti-slip part 40 is the edge line of the limiting member 20 at the limiting end 202, and the edge line is a wavy line. In this way, it can reduce the risk of injury to personnel during use.
[0059] Of course, the structure of the anti-slip part 40 is not limited to this. For example, an anti-slip strip can be provided and attached to the limiting member 20 on the limiting end 202.
[0060] In some embodiments, such as Figures 2-5 As shown, the limiting member 20 includes: an extension arm plate 23 and a pressing arm plate 24. One end of the extension arm plate 23 is a connecting end 201. The extension arm plate 23 is an arc-shaped plate or a straight plate. One end of the pressing arm plate 24 is a limiting end 202. The other end of the pressing arm plate 24 is connected to the other end of the extension arm plate 23. The pressing arm plate 24 is an arc-shaped plate or a straight plate.
[0061] This design makes the limiting member 20 longer, so that the limiting end 202 can extend a certain distance relative to the substrate 10, thereby making it easy to lock onto one side of the second window 300 and ensuring the reliability of limiting the second window 300.
[0062] Specifically, the extension arm plate 23 gradually moves away from the substrate 10 in the direction toward the pressing arm plate 24. The pressing arm plate 24 can also gradually move away from or toward the substrate 10 in the direction away from the extension arm plate 23. If the pressing arm plate 24 also gradually moves away from the substrate 10 in the direction away from the extension arm plate 23, the inclination of the pressing arm plate 24 is less than that of the extension arm plate 23. This avoids the limiting member 20 from being too wide and prevents the limiting member 20 from failing to retract into the gap between the first window 200 and the second window 300 when pressed.
[0063] In some specific embodiments, such as Figure 3 As shown, the pressing arm plate 24 is a straight plate, and the pressing arm plate 24 is arranged parallel to the base plate 10. This is not only aesthetically pleasing, but also facilitates the pressing arm plate 24 to adhere to the base plate 10 when the limiting member 20 is pressed. As a result, the entire limiting device 100 is made thinner, making it easier to fit into the gap between the first window 200 and the second window 300.
[0064] With this configuration, the gap between the first window 200 and the second window 300 is narrower, allowing the limiting device 100 to function effectively and further increasing the types of windows that the limiting device 100 can be used for.
[0065] Furthermore, in its natural state (i.e., when the limiting member 20 is not under force), the extension arm plate 23 gradually moves away from the substrate 10 in the direction toward the pressing arm plate 24. That is, the distance between the extension arm plate 23 and the substrate 10 gradually increases from the connecting end 201 to the limiting end 202. In its natural state (i.e., when the limiting member 20 is not under force), the pressing arm plate 24 is arranged parallel to the substrate 10, so that when the extension arm plate 23 is pressed against the substrate 10, the pressing arm plate 24 is inclined to the substrate 10. Taking the example of the limiting device 100 being used to limit the upward opening range of the lower second window 300, when it is necessary to open the second window 300 upwards significantly, the extension arm plate 23 can be pressed so that the pressing arm plate 24 touches the first window 200. At this time, the pressing arm plate 24 is in a state where its lower end touches the first window 200, and the pressing arm plate 24 gradually extends upwards in the direction away from the first window 200. At this point, pull the second window 300 upwards. The second window 300 may press against the pressing arm plate 24, but the pressing arm plate 24 will not block the second window 300. Continue to pull the second window 300 upwards, and the second window 300 will continue to press the limiting member 20 against the first window 200 through the pressing arm plate 24.
[0066] In some embodiments, such as Figures 2-4 As shown, the limiting device 100 also includes an auxiliary spring arm 50, the two ends of which are a fixed end 501 and a free end 502. The fixed end 501 is connected to the substrate 10, and the free end 502 is located away from the substrate 10 and extends toward the limiting member 20.
[0067] In this way, the limiting capability of the limiting device 100 can be increased. Specifically, the auxiliary elastic arm 50 can assist the elastic arm 30 in slowly deforming and in quickly resetting.
[0068] Specifically, when the limiting member 20 is pressed towards the substrate 10, since the elastic arm 30 is a bent sheet metal part and the auxiliary elastic arm 50 is also an elastic arm, when the limiting member 20 is pressed, it presses on the auxiliary elastic arm 50 and the elastic arm 30, causing the auxiliary elastic arm 50 and the elastic arm 30 to deform. At the same time, the limiting member 20 is close to the substrate 10, so that the entire limiting position 100 can be compressed into the gap between the first window 200 and the second window 300. At this time, moving the second window 300 upward will open the second window 300, and it is no longer restricted by the limiting end 202 of the limiting member 20.
[0069] Then the second window 300 is moved down. When it moves to below the limiting end 202 of the limiting member 20, the auxiliary spring arm 50 and the elastic arm 30 are reset. At the same time, the limiting member 20 is pushed away from the substrate 10 so that the limiting end 202 of the limiting member 20 can be restricted above the second window 300 again.
[0070] In some specific embodiments, such as Figures 2-4As shown, in the direction from the fixed end 501 to the free end 502, the auxiliary spring arm 50 gradually approaches the connecting end 201. That is, the auxiliary spring arm 50 is inclined relative to the substrate 10 and tilted towards the connecting end 201. With this configuration, when the limiting member 20 is pressed, the auxiliary spring arm 50 can be clamped between the substrate 10 and the limiting member 20, thereby being protected. This prevents the auxiliary spring arm 50 from deforming and jamming the second window 300.
[0071] Furthermore, a through hole 11 is provided in the middle of the substrate 10, and a fixed end 501 is connected to the side of the through hole 11. The auxiliary spring arm 50 is formed by bending the material of the substrate 10 located at the through hole 11. The through hole 11 provides room for the movement of the auxiliary spring arm 50. When the limiting member 20 is pressed against the substrate 10, the auxiliary spring arm 50 can retract into the through hole 11, making the limiting device 100 thinner overall, which is convenient for retraction into the gap between the first window 200 and the second window 300.
[0072] Furthermore, bending the material of the substrate 10 located at the through-hole 11 to form the auxiliary spring arm 50 not only reduces cost but also makes it less prone to breakage and highly reliable. In addition, the bending process allows the auxiliary spring arm 50 to maintain strong elasticity.
[0073] Optionally, the auxiliary spring arm 50 has a hook 55 formed at its free end 502 that bends toward the elastic arm 30. In this way, when the limiting member 20 is pressed against the substrate 10, the auxiliary spring arm 50 can be clamped between the substrate 10 and the limiting member 20, and the hook 55 on the auxiliary spring arm 50 abuts against the substrate 10 or the limiting member 20, which can reduce wear and improve the elasticity during reset.
[0074] Furthermore, the elastic arm 30 is arc-shaped, which is not only aesthetically pleasing but also highly elastic.
[0075] Furthermore, the base plate 10, the limiting member 20, the elastic arm 30, and the auxiliary elastic arm 50 of the limiting device 100 are integrated sheet metal parts, and the base plate 10, the limiting member 20, the elastic arm 30, and the auxiliary elastic arm 50 have the same thickness, which facilitates processing.
[0076] In this application, the method by which the substrate 10 is fixed to the first window 200 is not limited. For example, an adhesive layer is provided on the back side of the substrate 10, which can be directly adhered to the first window 200. Specifically, the adhesive layer is provided on the side of the substrate 10 away from the limiting member 20, which facilitates the adhesion of the first window 200.
[0077] Optionally, the limiting device 100 can be a steel plate or other metal plate.
