Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, and in particular to an automatic latch for extremely narrow doors and windows. Background Technology

[0002] Casement-sliding integrated doors and windows combine the advantages of good ventilation (casement windows) and space-saving design (sliding windows), making them widely used. However, these integrated doors and windows cannot operate in both casement and sliding modes simultaneously. Therefore, traditional bolt locks are installed at the top or bottom of the door / window sash to secure it. When the door / window needs to slide, the bolt is manually pushed into the bolt hole, locking the casement door / window sash (which rotates around a pivot or hinge) in the track, ensuring the sliding door / window sash (which moves on the track or rail). When the casement door / window needs to open, the bolt is manually pulled out of the bolt hole, allowing the door / window sash to rotate around a pivot or hinge. This manual bolt locking system is cumbersome and negatively impacts the user experience.

[0003] Furthermore, the minimalist interior design style has become increasingly popular in recent years. This style emphasizes simplicity, elegance, and aesthetics, leading to a surge in demand for ultra-narrow frame doors and windows. These windows, also known as ultra-narrow-frame doors and windows, typically have frame widths ranging from 1.6 to 4.5 centimeters. Compared to traditional doors and windows, their narrower frame allows for greater light transmission while maintaining strength. While the narrower frame of ultra-narrow windows offers a better visual effect, it also means less space for installing accessories. Traditional latches, designed for ordinary doors and windows, cannot be used on ultra-narrow windows. Even if they were to be used, they would likely result in large areas of exposed hardware, negatively impacting the overall visual appeal and creating a disharmonious effect with the minimalist design style.

[0004] The technical problem to be solved by this utility model is: how to solve the problem that existing latches require manual insertion and removal and are too bulky to be suitable for extremely narrow doors and windows. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic latch for extremely narrow doors and windows, which has a simple and compact structure and can automatically insert and remove the latch through collision and separation.

[0006] The technical solution adopted by this utility model is as follows: an automatic latch for extremely narrow doors and windows, including a housing and a telescopic assembly installed on the housing, and an angle bracket connected to one end of the housing. The telescopic assembly includes a trigger element slidably connected to the housing, a sliding element built into the housing, and a pin connected to the sliding element. The trigger element is located on one side of the housing, with one end protruding from the housing and the other end connected to the sliding element. The sliding element slides in cooperation with the housing, and the sliding direction of the trigger element is perpendicular to the sliding direction of the sliding element. One end of the pin is connected to the sliding element, and the other end extends toward the angle bracket. The angle bracket and the housing are provided with a sliding groove for the pin to pass through. When the trigger element is subjected to external force, it slides toward the inside of the housing, thereby driving the sliding element to slide inside the housing, and then driving the pin to retract toward the inside of the housing.

[0007] The automatic latch for ultra-narrow doors and windows of this application is installed on the side frame of the hinged door leaf away from the door (window) frame. When the sliding door leaf overlaps with the hinged door leaf, the side frame of the sliding door leaf slides the trigger element into the housing, thereby causing the pin to retract into the housing. When the sliding door leaf separates from the hinged door leaf, the pin extends out of the corner bracket under its own weight or other driving force, while the trigger element extends out of the housing, realizing the automatic insertion of the pin. That is, the pin is pulled out or inserted by the collision or separation of the sliding door leaf and the trigger element. In addition, the housing is connected to the corner bracket. When assembling the door leaf frame, the housing can be installed and fixed to the door leaf frame together with the corner bracket. Moreover, the automatic latch is set on the side of the door leaf frame, so that the automatic latch is integrated with the door leaf frame, making the overall structure more compact, easier to install, and with better visual effect.

[0008] In some embodiments, the slider includes a slider and a stopper. The slider is slidably connected to the housing, and the stopper is disposed on the side of the slider near the trigger. The stopper has a first inclined portion that abuts against the trigger.

[0009] By adopting the above technical solution, the first inclined part cooperates with the trigger to convert the horizontal movement of the trigger into the vertical movement required by the pin.

[0010] In some embodiments, the trigger member has a second inclined portion corresponding to the first inclined portion at the end near the abutment member.

[0011] By adopting the above technical solution, by setting a second inclined part on the trigger element that cooperates with the first inclined part, the contact area between the trigger element and the abutment element can be increased, thereby improving the reliability of the transmission structure.

[0012] In some embodiments, the slider and the abutment are detachably connected, the slider is provided with a slot, and the abutment is provided with a block that cooperates with the slot.

[0013] By adopting the above technical solution, the slider and the abutment can be detachably connected through the cooperation of the card block and the card slot. This allows for quick assembly and disassembly of the abutment and the slider, facilitating the replacement of the abutment, a vulnerable part, and reducing maintenance costs.

[0014] In some embodiments, a limiting block is provided on the inner wall of the housing, and a limiting groove corresponding to the limiting block is provided on the abutment member.

[0015] By adopting the above technical solution, the limiting block and the limiting groove cooperate to restrict the movement trajectory of the abutment and prevent the abutment from separating from the slider.

[0016] In some embodiments, the housing has a cavity for the sliding member to slide in, the inner wall of the cavity is provided with a guide block, and the sliding member is provided with a guide groove that slides with the guide block.

[0017] By adopting the above technical solution, the movement trajectory of the sliding component can be restricted through the cooperation of the guide block and the guide groove, making the insertion and removal operation of the pin more precise.

[0018] In some embodiments, the housing includes a base and a top cover, which are either an integral structure or a separate structure. The top cover is located on the side of the base near the trigger element. The top cover has a protrusion extending into the cavity. The sliding element has a clearance groove corresponding to the protrusion. The protrusion has a receiving cavity inside for the trigger element to slide.

[0019] Using the above technical solution, the protruding post can support the top cover, making the structure of the top cover more stable. In addition, the protruding post can provide space for the cavity, making the movement of the trigger more stable. Opening a clearance groove on the sliding part can prevent the sliding part from interfering with the protruding post when it moves.

[0020] In some embodiments, the housing also includes a first bottom cover detachably connected to the base, the first bottom cover being disposed on the side of the base away from the top cover.

[0021] Using the above technical solution, the bottom cover can cover the cavity, so that the cavity forms a relatively closed structure to ensure that the sliding of the sliding component is not disturbed. The bottom cover and the base are detachably connected, which can facilitate the installation of sliding components, trigger components and other parts.

[0022] In some embodiments, the housing also includes a second bottom cover detachably connected to the top cover. The second bottom cover is disposed at one end of the protrusion near the first bottom cover. A second reset member is disposed between the second bottom cover and the trigger member. The second reset member is used to drive the trigger member to extend out of the housing.

[0023] By adopting the above technical solution and setting a second bottom cover, it is convenient to install the trigger and the second reset components separately.

[0024] In some embodiments, a first reset member is provided between the slider and the housing, the first reset member being used to drive the pin to extend out of the corner bracket.

[0025] By adopting the above technical solution, the first reset component can provide driving force for the pin to extend out of the corner bracket. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] Please see Figures 1 to 8An automatic latch 100 for extremely narrow doors and windows, according to a preferred embodiment of the present invention, includes a housing 10 and a telescopic assembly 20 mounted on the housing 10, and also includes a corner bracket 30 connected to one end of the housing 10. The telescopic assembly 20 includes a trigger 21 slidably connected to the housing 10, a sliding member 22 built into the housing 10, and a pin 23 connected to the sliding member 22. The trigger 21 is disposed on one side of the housing 10, with one end of the trigger 21 protruding from the housing 10 and the other end connected to the sliding member 22. The sliding member 22 is slidably engaged with the housing 10, and the sliding direction of the trigger 21 is perpendicular to the sliding direction of the sliding member 22. One end of the pin 23 is connected to the sliding member 22, and the other end extends toward the corner bracket 30. The corner bracket 30 and the housing 10 are provided with a groove for the pin 23 to pass through. When the trigger 21 is subjected to external force, it slides toward the inside of the housing 10, thereby driving the sliding member 22 to slide inside the housing 10, and then driving the pin 23 to retract toward the inside of the housing 10. The automatic latch 100 for ultra-narrow doors and windows of this application is installed on the side frame of the hinged door leaf away from the door (window) frame. When the sliding door leaf overlaps with the hinged door leaf, the side frame of the sliding door leaf slides the trigger 21 into the housing 10, thereby causing the pin 23 to retract into the housing 10, realizing the removal of the pin 23. When the sliding door leaf separates from the hinged door leaf, the pin 23 extends out of the corner bracket 30 under its own weight or other driving force, while the trigger 21 extends out of the housing 10, realizing the automatic insertion of the pin 23. That is, the pin 23 is removed or inserted by the collision or separation of the sliding door leaf and the trigger 21. In addition, the housing 10 is connected to the corner bracket 30. When assembling the door leaf frame, the housing 10 can be installed and fixed on the door leaf frame together with the corner bracket 30. Moreover, the automatic latch is set on the side of the door leaf frame, so that the automatic latch is integrated with the door leaf frame, the overall structure is more compact, the installation is more convenient, and the visual effect is better.

[0039] like Figure 1 and Figure 2 As shown, the corner bracket 30 includes a first connecting part 31 and a second connecting part 32.

Optionally, the first connecting part 31 and the second connecting part 32 are set at 90°.

[0040] Preferably, in order to make the automatic latch structure more compact, the width of the first connecting part 31 is approximately equal to the width of the housing 10, and the thickness of the first connecting part 31 is approximately equal to the thickness of the housing 10.

[0041] In one embodiment, such as Figure 3 and Figure 4As shown, the slider 22 includes a slider 221 and a stop 222. The slider 221 is slidably connected to the housing 10. The stop 222 is disposed on the side of the slider 221 near the trigger 21, and the stop 222 is provided with a first inclined portion 223 that abuts against the trigger 21. The first inclined portion 223 cooperates with the trigger 21 to convert the horizontal movement of the trigger 21 into the vertical movement required by the pin 23.

[0042] Correspondingly, the trigger member 21 is provided with a second inclined portion 211 corresponding to the first inclined portion 223 at one end near the abutment member 222. By providing the second inclined portion 211 on the trigger member 21 that cooperates with the first inclined portion 223, the contact area between the trigger member 21 and the abutment member 222 can be increased, thereby improving the reliability of the transmission structure.

[0043] Furthermore, the slider 221 and the abutment 222 are detachably connected. In this embodiment, the slider 221 is provided with a slot 224, and the abutment 222 is provided with a locking block 225 that cooperates with the slot 224. The detachable connection between the slider 221 and the abutment 222 is achieved by the cooperation of the locking block 225 and the slot 224, which allows for quick assembly and disassembly of the abutment 222 and the slider 221. This facilitates the replacement of the abutment 222, a vulnerable part, and reduces maintenance costs.

[0044] Furthermore, a limiting block 12 is provided on the inner wall of the housing 10, and a limiting groove 226 corresponding to the limiting block 12 is provided on the abutment member 222. The limiting block 12 and the limiting groove 226 cooperate to restrict the movement trajectory of the abutment member 222 and prevent the abutment member 222 from separating from the slider 221.

[0045] In other embodiments, the slider 221 and the abutment 222 can also be detachably connected by means of fasteners, threaded connections, or other methods. In one embodiment, the slider 221 and the abutment 222 can also be configured as an integrally formed structure.

The protrusion 141 can support the top cover 14, making the structure of the top cover 14 more stable. In addition, the protrusion 141 can provide space for constructing the receiving cavity 142, making the movement of the trigger member 21 more stable. The clearance groove 228 on the sliding member 22 can prevent interference between the sliding member 22 and the protrusion 141 when the sliding member 22 moves.

[0048] In this embodiment, the base 13 and the top cover 14 are separate structures. The guide block 11 and the chamber are disposed on the base 13, and the base 13 and the top cover 14 are connected by fasteners.

[0049] In this embodiment, the pin 23 is detachably connected to the base 13. Optionally, the pin 23 and the base 13 can be detachably connected by means of fasteners, interference fits, threaded connections, or snap-fits.

[0050] Furthermore, to prevent the trigger 21 from easily detaching from the receiving cavity 142, a flange 212 is provided at the bottom of the trigger 21 (the end housed within the receiving cavity 142), and a retaining ring (not shown in the figure) with a width smaller than the flange 212 is provided at the top of the receiving cavity 142. The retaining ring cooperates with the flange 212 to restrict the trigger 21 from detaching from the top of the receiving cavity 142. At the same time, to make the sliding trajectory of the trigger 21 more precise, a groove 213 is provided on the flange 212, and a protrusion that cooperates with the groove 213 is provided on the inner wall of the receiving cavity 142.

[0051] In some embodiments, the housing 10 further includes a first bottom cover 15 detachably connected to the base 13, the first bottom cover 15 being disposed on the side of the base 13 away from the top cover 14. The bottom cover can cover the cavity, forming a relatively closed structure to ensure that the sliding member 22 slides without interference. The detachable connection between the bottom cover and the base 13 facilitates the installation of components such as the sliding member 22 and the trigger member 21. Optionally, the first bottom cover 15 is connected to the base 13 by screws.

[0052] Furthermore, the housing 10 also includes a second bottom cover 16 detachably connected to the top cover 14. The second bottom cover 16 is disposed at the end of the protrusion 141 near the first bottom cover 15. A second reset member 25 is disposed between the second bottom cover 16 and the trigger member 21, and the second reset member 25 is used to drive the trigger member 21 to extend out of the housing 10. By providing the second bottom cover 16, it is convenient to install the trigger member 21 and the second reset member 25 separately. Preferably, the second bottom cover 16 is connected to the protrusion 141 by screws.

[0053] In this embodiment, the limiting block 12 is disposed on the second bottom cover 16.
