Description

Technical Field

[0001] This utility model belongs to the field of building door and window structure technology, and in particular relates to a sliding door with a guardrail and screen door structure. Background Technology

[0002] Sliding doors are popular among homeowners because of their sliding opening mechanism, which allows them to open wide without taking up much space.

[0003] Simple sliding doors have shortcomings. Their weatherstripping seals are not tight, and they don't slide smoothly, making them unsuitable for use as exterior doors or windows. If a sliding door is used to enclose a balcony, homeowners will worry about drafts and leaks, as well as the safety of the door being on the outside.

[0004] Most existing sliding doors use weatherstripping for sealing, which is suitable for indoor use, but can lead to sealing problems when used on the exterior. Weatherstripping seals are relatively sparse; if the seal is too good, sliding will be difficult; if the sliding is smooth, the seal will be unsatisfactory. Poor sealing not only causes air leakage but also poor sound insulation, allows water to enter during rain, and prevents dust from being trapped. Furthermore, dust easily accumulates in the grooves of the track.

[0005] When sliding doors are used on balconies, their wind pressure resistance may be insufficient, and they are prone to deformation after long-term use. It is also necessary to consider the risk of the door falling off. Utility Model Content

[0006] This utility model addresses the above-mentioned problems by providing a sliding door that is smooth to push and pull and has a reliable seal.

[0007] This utility model adopts the following technical solution: It includes a frame, within which a fixed side and an open side are provided. The open side is located on the indoor side, and the fixed side is located on the outdoor side. The features are: a guardrail and a screen door are provided between the mullion and the frame on the fixed side; the upper and lower parts of the open side are connected to the frame via a guide mechanism; mounting plates are provided on both the mullion and the frame on the fixed side, and the guardrail and screen door are located between the two mounting plates; sealing strips are provided between the mullion and the two mounting plates and the open side.

[0008] As a preferred embodiment of this utility model, the guiding mechanism includes guide grooves disposed on the upper and lower parts of the frame; transverse guide wheels that cooperate with the guide grooves are disposed on the upper and lower ends of the opening side; a support guide rail is disposed in the guide groove at the lower part of the frame; and a traveling wheel that cooperates with the support guide rail is disposed at the bottom of the opening side.

[0009] Furthermore, the transverse guide wheel is provided with a self-adjusting mechanism. When the opening side is in the closed position, the self-adjusting mechanism presses the opening side against the fixed side, so that the sealing strip is compressed to form a seal. When the opening side is within the opening range, the self-adjusting mechanism controls the distance between the opening side and the fixed side to maintain the sealing strip in a non-compressed state.

[0010] As another preferred embodiment of this utility model, the guardrail is a glass panel, and the mullion profile and the frame are provided with cantilever arms that cooperate with the outer surfaces of both sides of the glass panel. The frame is provided with compensating profiles corresponding to the upper and lower sides of the glass panel and the screen door. The mounting buckle is snapped into the mullion profile and the frame, and the mounting buckle is provided with a pressing edge that cooperates with the inner surface of the glass panel.

[0011] Furthermore, fixing strips are provided between the pressing edge and the cantilever and the glass panel.

[0012] Furthermore, the sealing strip is disposed in the groove of the compensating profile and the mounting plate; the opening side includes a door frame, and hook-edge profiles are provided on both sides of the door frame, and another groove of sealing strip is provided on the hook-edge profiles.

[0013] Furthermore, the rubber strip groove of the lower compensation profile is provided on the water-blocking arm that protrudes upward from the edge of the compensation profile.

[0014] Furthermore, a pad is provided between the bottom of the glass panel and the compensation profile.

[0015] As a fourth preferred embodiment of this utility model, the frame is provided with a hardware groove that mates with the opening side.

[0016] The beneficial effects of this utility model are as follows: 1. Significantly improved sealing performance: By setting multiple sealing strips on the mullion, mounting plate, compensation profile and hook edge profile, and using the self-adjusting mechanism in the guide mechanism to press and cooperate when closed, the opening side can generate a pressing force on the fixed side in the locked state, thereby achieving multiple seals in the circumferential and vertical directions, which significantly improves the airtightness and watertightness of the door.

[0017] 2. Smooth opening and closing with automatic pressing: The guide groove in the guide mechanism works with the horizontal guide wheel to maintain smooth sliding during opening. At the closing end, the self-adjusting mechanism can automatically press the door leaf to the fixed side, which not only ensures low-resistance sliding when opening, but also ensures tight sealing when closing, taking into account both smoothness and sealing performance.

[0018] 3. Integrated protection and mosquito prevention functions: A guardrail and a screen door are installed between the fixed side mullion and the frame. The guardrail can be made of glass panel structure, which has both safety protection and isolation functions; the screen door is used to prevent mosquitoes and insects, and is installed on the side of the fixed side, that is, the outdoor side. Therefore, it does not affect the opening and closing of the door, forming a safe, ventilated and comfortable enclosed space.

[0019] 4. Reasonable drainage and seepage prevention structure: The edge of the lower compensation profile is equipped with an upward-protruding water-blocking arm, and a sealing strip is installed in its rubber strip groove, which can effectively prevent external rainwater from seeping in; a gap can be formed between the pad and the compensation profile under the glass panel, which is conducive to drainage and improves the drainage capacity and weather resistance of the entire door system.

[0020] 5. Stable structure and reliable assembly: The mounting plate is connected to the mullion and frame through a snap-fit ​​method to form a reliable assembly structure; the hardware grooves set on the frame can precisely match the hardware on the opening side to ensure smooth sliding of the door leaf, high structural strength and long service life.

Detailed Implementation

[0025] This utility model includes a frame 5, within which a fixed side 1 and an open side 2 are provided. The open side 2 is located on the indoor side, and the fixed side 1 is located on the outdoor side. A guardrail 4 and a screen door 3 are provided between the mullion 10 of the fixed side 1 and the frame 5. The upper and lower parts of the open side 2 are connected to the frame 5 through a guide mechanism. Mounting plates 11 are provided on both the mullion 10 of the fixed side 1 and the frame 5, and the guardrail 4 and screen door 3 are located between the two mounting plates 11. Sealing strips 9 are provided between the mullion 10 and the two mounting plates 11 and the open side 2. Through multi-point sealing with sealing strips, airtightness, watertightness, and sound insulation performance are simultaneously improved. At the same time, the guardrail 4 and screen door 3 are structurally integrated, taking into account both safety protection and mosquito prevention functions.

[0026] The transverse guide wheel 16 is equipped with a self-adjusting mechanism 18. When the opening side 2 is in the closed position, the self-adjusting mechanism 18 presses the opening side 2 against the fixed side 1, compressing the sealing strip 9 to form a seal. When the opening side 2 is within the opening range, the self-adjusting mechanism controls the distance between the opening side 2 and the fixed side 1, keeping the sealing strip 9 in a non-compressed state. This guide mechanism ensures smooth sliding during opening and achieves automatic compression during closing using the self-adjusting mechanism 18, thus enabling the door to combine easy opening with high-sealing locking, resolving the contradiction of traditional sliding doors where "smooth sliding and tight sealing are difficult to achieve simultaneously."

[0027] The self-adjusting mechanism 18 can use readily available existing technology: pulley assemblies from German Roto Hardware, which can realize the functions of pressing the opening side and releasing the opening side as described in this utility model.

[0028] A support rail 19 is provided in the guide groove 17 at the bottom of the frame 5; a traveling wheel 20 that cooperates with the support rail 19 is provided at the bottom of the opening side 2. This structure improves the support stability of the door leaf, makes the door leaf slide with uniform force and run smoothly, effectively reduces wear and noise, and ensures the smoothness and durability of the door body during long-term use.

[0029] The guardrail 4 is a glass panel 21. The mullion 10 and frame 5 are provided with cantilevered arms that mate with the outer surfaces of both sides of the glass panel 21. Compensating profiles 15 are provided on the frame 5 corresponding to the upper and lower sides of the glass panel 21 and the screen door 3. The mounting plate 11 is snapped into the mullion 10 and frame 5, and the mounting plate 11 has a pressing edge 12 that mates with the inner surface of the glass panel 21. This structure ensures that the glass panel 21 is firmly installed, evenly stressed, and easy to install and disassemble.

[0030] Fixing strips 13 are provided between the clamping edge 12 and the cantilever and the glass panel 21. Multiple strips provide flexible support and cushioning to absorb vibration and prevent hard contact between the glass and the profile.

[0031] The sealing strip 9 is disposed in the groove of the sealing strip on the compensation profile 15 and the mounting plate 11; the opening side 2 includes a door frame 7, and hook-edge profiles 6 are provided on both sides of the door frame 7. Another groove of sealing strip 9 is provided on the hook-edge profile 6. By forming multiple circumferential and vertical sealing strips between the fixed side 1 and the opening side 2, an all-round sealing system is formed, which significantly improves the air tightness, water tightness and sound insulation performance.

[0032] The rubber strip groove of the lower compensation profile 15 is set on the water-blocking arm 14 that protrudes upward from the edge of the compensation profile 15. The combination of the water-blocking arm 14 structure and the rubber strip can effectively prevent external rainwater from seeping into the door area and form a drainage channel, enhancing the waterproof, moisture-proof and weather-resistant performance of the door.

[0033] A pad is provided between the glass panel 21 and the compensating profile 15. The pad provides lower support for the glass and can also form a gap to ensure that the bottom of the glass is evenly stressed and that the drainage channel is unobstructed, which helps to prevent water accumulation and cracking at the bottom edge of the glass.

[0034] The frame 5 is provided with a hardware groove 8 that mates with the opening side 2.

[0035] Example: Figures 1 to 3 As shown, this utility model includes a frame 5, a fixed side 1, and an openable side 2. The openable side 2 is located on the indoor side, and the fixed side 1 is located on the outdoor side. A guardrail 4 and a screen door 3 are provided between the mullion 10 of the fixed side 1 and the frame 5. The upper and lower parts of the openable side 2 are connected to the frame 5 through a guide mechanism.

[0036] The guiding mechanism includes guide grooves 17 located at the upper and lower parts of the frame 5, and transverse guide wheels 16 that cooperate with the guide grooves 17 are respectively provided at the upper and lower ends of the opening side 2. This invention includes a self-adjusting mechanism 18. When the opening side 2 is in the closed position, the self-adjusting mechanism 18 presses the opening side 2 against the fixed side 1, compressing the sealing strip 9 between the opening side 2 and the fixed side 1 to form a reliable seal. When the opening side 2 is in the open position, the self-adjusting mechanism 18 controls the opening side and the fixed side to separate, and the sealing strip 9 is in a non-compressed state, ensuring smooth pushing and pulling. A support rail 19 is also provided in the guide groove 17 at the lower part of the frame 5, and a traveling wheel 20 that cooperates with the support rail 19 is provided at the bottom of the opening side 2 to support and guide the movement of the door leaf on the opening side 2.

[0037] like Figure 2 As shown, the frame 5 is divided into a fixed side 1 and an opening side 2. The opening side 2 is located indoors, and the fixed side 1 is located outdoors. Centered on the mullion 10 of the fixed side 1, a glass panel 21, a guardrail 4, and a screen door 3 are sequentially installed from the mullion 10 to the outer frame 5 on the fixed side 1. The guardrail 4 uses a glass panel 21 structure, serving as a safety protection and isolation function. The screen door 3 is installed on the outside of the guardrail 4 for mosquito and insect prevention. The screen door 3 is a foldable structure, located between two mounting plates 11. The mounting plates 11 are respectively engaged with the mullion 10 profile and the frame 5. The screen door 3 is detachable for cleaning and maintenance. This structure ensures that both the guardrail 4 and the screen door 3 are located outdoors, without occupying external space or affecting the opening and closing of the door, achieving continuous mosquito prevention and safety protection functions.

[0038] The glass panel 21 is embedded, with its outer side fitting against the cantilever on the mullion 10 and frame 5, and its inner side secured by the clamping edge 12 on the mounting plate 11. Fixing strips 13 are provided at both the cantilever and the clamping edge 12 to flexibly clamp the glass panel 21, preventing loosening and breakage while improving sealing. The mounting plate 11 also has grooves for the sealing strip 9 to further enhance the sealing effect.

[0039] like Figure 3 As shown, a compensating profile 15 is provided on the lower frame 5 on the outdoor side to make the lower frame 5 a flat surface. The edge of the compensating profile 15 protrudes upward to form a water-blocking arm 14. The water-blocking arm 14 is provided with a rubber strip groove and a sealing strip 9 is installed. When pressed, it can effectively block rainwater from flowing into the door sash area, thereby improving the water tightness. A pad is provided below the glass panel 21, and a gap is left between the pad and the compensating profile 15 for drainage and buffer support.

[0040] The opening side 2 includes a door leaf frame 7 and a hook edge profile 6. The hook edge profile 6 is provided with a rubber strip groove and a sealing rubber strip 9 is installed, so that when the door leaf of the opening side 2 is closed, it forms an annular seal with the rubber strip of the fixed side 1, the middle mullion 10 and the mounting plate 11. Two sealing structures are formed in the vertical direction of the hook edge to achieve a three-dimensional sealing effect.

[0041] When opened, the handle drives the traveling wheel 20 on the opening side 2 to slide along the support guide rail 19, and the guide wheel runs smoothly in the guide groove 17, allowing the door to open smoothly. When closed, under the control of the self-adjusting mechanism 18, the door leaf on the opening side 2 is pressed against the fixed side 1, and the sealing strip 9 is deformed under pressure, achieving a high-efficiency seal. A multi-point linkage locking mechanism can be set around the door leaf, which can further improve the overall sealing performance after locking. The locking mechanism is a readily available technology.

[0042] The frame 5 can be made of thermally broken aluminum alloy profile. The four frame frames 5 are connected by nailing through nail slots to ensure connection strength and overall stability. The frame 5 is also provided with hardware slots 8 for installing hardware that cooperates with the opening side 2, including guide wheels, handles and locking mechanisms, so that the door can be opened and closed easily, positioned accurately and used reliably.

[0043] This invention can be applied to enclosed balconies on building facades, as well as to passageway openings. While achieving a large opening area, the structure possesses excellent airtightness, watertightness, safety protection, and mosquito-proof properties, providing users with a complete, comfortable, and reliable user experience.
