Description

Technical Field

[0001] This invention relates to the field of door and window technology, and more particularly to double doors and windows for antique-style buildings. Background Technology

[0002] In old, antique-style buildings, doors and windows often feature a multi-leaf, double-leaf structure. Taking a multi-leaf, double-leaf door as an example, it means that multiple double doors are located within the same door frame. Each double door consists of two door panels hinged to the door frame via a hinged hinge. Figure 1 As shown.

[0003] There will be gaps between the double doors in antique-style buildings, such as... Figure 2 As shown, the gap is in the shape of a straight line, and the gap exists not only between the door panel and the door frame, but also... Figure 2 As shown in Figure A, there are gaps between the two door panels of each double door and between the two door panels of two adjacent double doors, as shown in Figure A. Figure 2 As shown in B and C, the external environment can directly enter the room through the straight gap.

[0004] The purpose of gaps is to allow room for the deformation of wooden doors and windows after being exposed to wind and sun. However, this also means that wooden doors and windows cannot be closed tightly. Moisture, noise and air can spread into the room through the gaps, resulting in unsatisfactory waterproof sealing, sound insulation and heat insulation performance of this type of double door.

[0005] The conventional solution is to install simple sealing strips inside the gaps. However, the practical effect of these sealing strips is limited; they cannot effectively isolate the outdoor environment and are not conducive to the protection of the interior building. Furthermore, during the opening and closing of the door, the lack of cushioning causes the door panel to directly impact the door frame, producing loud noise and even causing damage. Based on this, a sealing structure for the gaps of double doors or windows is proposed, which can be applied to the double doors and windows of newly constructed antique-style buildings. Summary of the Invention

[0006] To address the limited sealing effect of conventional sealing strips in sealing gaps, this invention provides double doors and windows for antique-style buildings. It optimizes the sealing structure, enabling excellent sealing of multiple gaps, effectively preventing the entry of moisture, noise, and air, and isolating the outdoor environment while protecting the interior building.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] The antique-style double doors and windows include a door frame and multiple double doors. Each double door includes two double door panels. The door panels and the door frame are hinged together by a door hinge to allow the door panels to rotate. There are gaps between the door panels and the door frame, between the two door panels of each double door, and between the two door panels of two adjacent double doors. It also includes sealing unit one, sealing unit two, and sealing unit three respectively set in the gaps, which constitutes a multi-directional sealing measure.

[0009] An "L"-shaped gap is formed between the door panel and the door frame joint surface. The sealing unit 1 is installed in the gap. The sealing unit 1 includes an anti-collision pad and a sealing pad 1 installed around the inside of the door frame. The cross-section of the anti-collision pad and the sealing pad 1 after being connected and combined is "L"-shaped, which matches the shape of the gap and can effectively seal the gap. The anti-collision pad and the sealing pad 1 are respectively attached to the edge of the long side and the thickness side of the door panel.

[0010] A continuous stepped gap is formed between the joint surfaces of the two door panels of each double door. The second sealing unit is installed in the gap. The second sealing unit includes a first anti-collision strip and a second sealing gasket. The first anti-collision strip is installed on the side of one of the door panels to prevent the two door panels of the double door from colliding when they are opened and closed. The second sealing gasket is installed on both door panels. The two second sealing gaskets are staggered and distributed on both sides of the first anti-collision strip. The second sealing gaskets are on both sides of the gap to facilitate a double sealing effect.

[0011] A straight gap is formed between the joint surfaces of the two door panels of two adjacent double doors. The sealing unit three is installed in the gap. The sealing unit three includes anti-collision strip two and sealing gasket three. The anti-collision strip two and sealing gasket three are installed on both door panels. Two sealing gasket three are placed between the two anti-collision strip two.

[0012] All three sealing gaskets (one, two, and three) have embedded absorbent strips to facilitate the absorption of small amounts of moisture.

[0013] Furthermore, a groove is provided on the inner side of the door frame to match the door panel, and an "L"-shaped gap is formed between the groove and the adjacent sides of the door panel. The "L"-shaped gap can expand the passage path of the external environment, and the extension of the passage path and the function of the sealing unit facilitate the effective sealing of the gap.

[0014] Furthermore, the anti-collision pad is a long strip structure made of elastic rubber, and there are four anti-collision pads. The four anti-collision pads are glued to the inside of the door frame to form an anti-collision frame, which facilitates the buffering of each door panel. One side of the anti-collision pad extends out of the gap and protrudes from the inner side of the door frame to form an extension section. The extension section fits tightly with the door panel. Multiple deformation grooves are opened in the extension section to increase the elastic deformation capacity of the extension section. One side of the extension section is a guide surface. The guide surface is an inclined surface and connects with the length surface of the door panel, so that rainwater and other water on the surface of the door panel can flow away from the gap along the guide surface.

[0015] Furthermore, a water-stop frame is provided on the inner side of the door frame. The water-stop frame protrudes outward from the inner side of the door frame. The extension section bends outward into a "" shape to form a guide section. The guide section is connected to the guide surface, which can prevent water flowing down the guide surface from flowing back, effectively improving the waterproofness of the double doors. The guide section covers the water-stop frame, and waterproof sealant is provided between the guide section and the water-stop frame to ensure a secure installation.

[0016] Furthermore, there are four sealing gaskets, which are adhered to the four sides of the door frame to form a sealing frame, facilitating the sealing of each door panel. Sealing gaskets one, two, and three are all elastic sealing rubber gaskets. Each of the sealing gaskets has a dovetail-shaped water-absorbing groove on one side, within which water-absorbing strips, which are water-absorbing sponge strips, are arranged. The water-absorbing grooves hold the water-absorbing strips in place, facilitating easy installation and removal.

[0017] Furthermore, each pair of doors has grooves on the opposite sides of its two door panels, which are staggered. These grooves, along with the thickness of the door panels, form a continuous stepped gap. This continuous stepped gap includes both vertically connected "𠃊"-shaped and "𠃍"-shaped gaps. This gap further extends the path of the external environment, and, in conjunction with the sealing unit two, facilitates an effective seal.

[0018] Furthermore, the first anti-collision strip is a solid long strip structure made of elastic rubber. The first anti-collision strip is vertically bonded to one of the door panels, and the second sealing gasket is bonded to the two grooves respectively, so that the second sealing gasket is vertically installed on the thickness surface of the door panel.

[0019] Furthermore, the second anti-collision strip is a solid strip structure made of elastic rubber. The second anti-collision strip is vertically bonded to the two door panels and is arranged at both ends of the straight gap. The second anti-collision strip is attached to the third sealing gasket. The two third sealing gaskets in the middle of the gap are tightly attached, and the joint surface is a continuous wavy surface, which makes it easier for the two third sealing gaskets to be joined more tightly and can better block the external environment.

[0020] The beneficial effects of the present invention through the above technical solution are:

[0021] The present invention features a reasonable structural design. First, different sealing units with different structures are selected according to the different locations of the gaps. Sealing unit one, sealing unit two, and sealing unit three all contain anti-collision components and sealing components. In this way, the double doors have the functions of buffering, sealing, sound insulation, and heat preservation, so that the performance of the double doors can be optimized. This effectively blocks the gaps and isolates the external environment from entering the room, ensuring a good indoor environment.

[0022] The anti-collision pad, anti-collision strip one, and anti-collision strip two of this invention constitute an anti-collision component. This component facilitates buffering between the door panel and the door frame, between the two door panels of a double door, and between the two door panels of two adjacent double doors. When the door panel presses against the anti-collision component, it buffers the impact force, preventing noise or even damage caused by direct collision when the door panels are closed, thus increasing the quietness of the double door. When the door panel is closed, the anti-collision component, deformed by compression, forms a seal within the gap, blocking the entry of the external environment. The anti-collision pad has an extension section, a guide surface, and a guide section, allowing for a tighter fit between it and the door panel, while also guiding moisture away from the gap, improving the waterproofness of the double door.

[0023] The sealing gaskets 1, 2, and 3 of this invention constitute a sealing component. This sealing component facilitates buffering between the door panel and the door frame, between the two door panels of a double door, and between the two door panels of two adjacent double doors. When the door panel presses against the sealing component, it prevents the transmission of sound, moisture, and air, ensuring a dry and clean indoor environment. Simultaneously, each of the sealing gaskets 1, 2, and 3 is detachably connected to an absorbent strip, giving the sealing component both sealing and absorbent functions. The sealing gaskets effectively block moisture, and even small amounts of moisture are prevented from flowing into the room by the absorbent strips. Once the absorbent strips are saturated with water and deformed under pressure, they can expel the moisture and then quickly return to their original shape. Attached Figure Description

Detailed Implementation

[0035] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0036] like Figures 3-10 As shown, the antique-style double doors and windows include a door frame 1 and multiple double doors. Each double door includes two hinged door panels 2. A hinge 3 is installed between the door panels 2 and the door frame 1, allowing the door panels 2 to be hinged and rotated. There are gaps between the door panels 2 and the door frame 1, between the two door panels 2 of each double door, and between the two door panels 2 of two adjacent double doors.

[0037] To achieve good waterproof sealing, sound insulation, and heat preservation performance for the double doors and windows, this embodiment also includes sealing unit 4, sealing unit 5, and sealing unit 6, which are respectively installed in the gaps. The sealing units 4, 5, and 6 have different structures and are installed in different locations, but their function is to prevent moisture, noise, and air from entering the room. Figure 3 As shown.

[0038] First, an "L"-shaped gap is formed between the mating surfaces of the door panel 2 and the door frame 1. This gap is obtained by modifying the door frame 1, specifically by creating a groove on the inner side of the door frame 1 to match the door panel 2. This groove surrounds the door frame 1, and the groove and the adjacent sides of the door panel 2 form an "L"-shaped gap. Here, the adjacent sides of the door panel 2 are the plane containing the length of the door panel 2 (length plane 7) and the plane containing the thickness of the door panel 2 (thickness plane 8). The "L"-shaped gap is formed by connecting a horizontal gap 9 near the outside and a vertical gap 10 near the inside.

[0039] To seal the "L"-shaped gap, a sealing unit 4 is installed within the gap. The sealing unit 4 includes anti-collision pads 41 and sealing pads 42 positioned around the inside of the door frame 1. Both anti-collision pads 41 and sealing pads 42 are fixed to the door frame 1 and do not move with the door panel 2. Figure 4 and Figure 5 As shown.

[0040] The anti-collision pad 41 is a long strip structure made of elastic rubber, which acts as an elastic buffer to prevent the door panel 2 from directly impacting the door frame 1. During installation, the anti-collision pad 41 is placed within the horizontal gap 9 of the "L"-shaped joint, also serving to seal the gap. The anti-collision pad 41 fits against the edge of the long side 7 of the door panel 2. There are four anti-collision pads 41, which are adhered to the inside perimeter of the door frame 1 to form an anti-collision frame; that is, the anti-collision frame is rectangular and arranged around the circumference of the door frame 1.

[0041] One side of the anti-collision pad 41 extends out of the gap and protrudes from the inner side of the door frame 1 to form an extension section 11. This extension section 11 effectively reduces the inner circle of the anti-collision frame, allowing the anti-collision pad 41 to have more contact with the edge of the long surface 7 of the door panel 2 through the extension section 11. The extension section 11 fits tightly against the door panel 2, and the door panel 2 presses the extension plate to seal the gap. Figure 6 As shown.

[0042] At the same time, multiple deformation grooves 12 are opened in the extension section 11. The deformation grooves 12 are rectangular grooves. Under the action of multiple deformation grooves 12, the deformation capacity of the extension section 11 is improved, and the edge of the door panel 2 fits more tightly with the extension section 11, which can better seal the horizontal gap 9 near the outside.

[0043] Given the aforementioned functions of the anti-collision pad 41, rainwater will inevitably accumulate on the surface of the door panel 2 during rainy weather. This rainwater flows downwards to the anti-collision pad 41 in the transverse gap 9. To prevent rainwater from accumulating between the joint surface of the door panel 2's length surface 7 and the extension section 11, one side of the extension section 11 is a guide surface 13. This guide surface 13 is inclined and connects to the length surface 7 of the door panel 2. Therefore, rainwater flowing vertically downwards along the surface of the door panel 2, after contacting the guide surface 13, flows along the guide surface 13 away from the transverse gap 9 of the "L"-shaped gap, allowing the rainwater to drain away promptly and preventing moisture from entering the room through the gap.

[0044] To prevent rainwater from flowing back, a water-stop frame 14 is installed on the inner side of the door frame 1. The water-stop frame 14 is a rectangular wooden frame, and it is an integral structure with the door frame 1. The water-stop frame 14 protrudes outward from the inner side of the door frame 1, effectively reducing the inner circle of the door frame 1. The water-stop frame 14 fits snugly against the extension section 11. The extension section 11 bends outward into a "」" shape to form a guide section 15, which connects to the guide surface 13. The guide section 15 covers the water-stop frame 14, and waterproof sealant is applied between the guide section 15 and the water-stop frame 14 to achieve a waterproof seal. In this way, rainwater on the guide surface 13 is discharged through the guide section 15 to the outside of the water-stop frame 14. The water-stop frame 14 acts as a threshold, preventing rainwater from flowing back and affecting the sealing of the anti-collision pad 41.

[0045] The entire anti-collision pad 41, including the extension section 11 and the deflector, has a cross-section resembling a "C" shape. The anti-collision pad 41 covers the outside of the waterstop frame 14, and one side of the anti-collision pad 41 is embedded into the transverse gap 9 of the "L"-shaped gap. After the door panel 2 closes and squeezes the anti-collision pad 41, the two fit tightly together. The anti-collision pad 41 can provide a buffering effect for the closing of the door panel 2, and also first seal the front end of the "L"-shaped gap.

[0046] Sealing gasket 42 is an elastic sealing rubber gasket, which plays a role in sealing the gap. It is used to close the rear end of the "L"-shaped gap. The division of the front and rear ends of the "L"-shaped gap refers to the flow of outside air into the room from the front end to the rear end.

[0047] When installing the sealing gasket 42, the sealing gasket 42 is placed inside the vertical gap 10 of the "L"-shaped gap. The sealing gasket 42 is attached to the thickness surface 8 of the door panel 2. There are four sealing gaskets 42. The four sealing gaskets 42 are glued to the four sides of the door frame 1 to form a sealing frame. That is, the sealing frame is rectangular and arranged around the door frame 1.

[0048] After both sealing gasket 42 and anti-collision pad 41 are installed, the end of sealing gasket 42 contacts anti-collision pad 41. Thus, the cross-section of the combined anti-collision pad 41 and sealing gasket 42 forms an "L" shape, which matches the "L"-shaped gap. The "L"-shaped gap increases the gap path, making it longer and more difficult for the outside environment to enter the room. Anti-collision pad 41 acts as a first seal, followed by sealing gasket 42. Together, they seal the gap simultaneously. This multi-pronged approach effectively improves the sealing between door panel 2 and door frame 1.

[0049] Secondly, a continuous stepped gap is formed between the joint surfaces of the two door panels 2 of each double door. This gap is obtained by modifying the door panels 2, that is, grooves are cut on the opposite surfaces of the two door panels 2 of each double door, and the two grooves are staggered. At this time, each door panel 2 is equivalent to having a protrusion and a groove, and the protrusion and groove on different door panels 2 fit together. The two grooves and the thickness surface 8 of the door panel 2 form a continuous stepped gap. The continuous stepped gap includes the "𠃊" shaped gap and the "𠃍" shaped gap that connect vertically. The continuous stepped gap runs through the thickness direction of the door panel 2. This gap is more complex than the "L" shaped gap.

[0050] To achieve a seal in the continuous stepped gap, a second sealing unit 5 is installed within the gap. The second sealing unit 5 includes a first anti-collision strip 51 and a second sealing gasket 52. Both the first anti-collision strip 51 and the second sealing gasket 52 are vertically arranged on the door panel 2, that is, along the height direction of the door panel 2. The two door panels 2 press against the second sealing unit 5 to achieve a seal in the gap. Figure 7 and Figure 8 As shown.

[0051] The anti-collision strip 51 is different from the anti-collision pad 41 in structure, but uses the same material. The anti-collision strip 51 is a solid strip structure made of elastic rubber. The anti-collision strip 51 is installed on the side of one of the door panels 2. The anti-collision strip 51 is vertically glued to the door panel 2 and is located in the middle of the gap.

[0052] Both door panels 2 are equipped with sealing gaskets 2 52, meaning that each pair of door panels 2 of each double door has one sealing gasket 2 52, which moves with each door panel 2. This also indicates that there are two sealing gaskets 2 52 in the sealing unit 2. These two sealing gaskets 2 52 have the same structure, material, and function; the sealing gaskets 2 52 are elastic sealing rubber gaskets. However, their installation positions are different. During installation, the sealing gaskets 2 52 are vertically glued into the two grooves respectively. The two sealing gaskets 2 52 are staggered and distributed on both sides of the anti-collision strip 1 51, that is, at the front and rear ends of the continuous stepped gap.

[0053] Compared to an "L"-shaped gap, the continuous stepped gap makes it more difficult for the external environment to enter the room, thus providing a certain degree of barrier effect. Meanwhile, sealing gasket 2 52, anti-collision strip 1 51, and sealing gasket 2 52 are arranged sequentially at the front, middle, and rear positions of the continuous stepped gap. When both door panels 2 are closed, all three completely fill the gap, effectively isolating it from the external environment. Anti-collision strip 1 51 acts as a buffer when the door panels 2 are opened and closed, while sealing gasket 2 52 provides a double sealing effect.

[0054] Then, a straight gap is formed between the joint surfaces of the two door panels 2 of two adjacent double doors, which is between the door hinges 3 of the two adjacent door panels 2. In order to seal the straight gap, a sealing unit 3 6 is set in the gap. The sealing unit 3 6 includes a second anti-collision strip 2 61 and a third sealing gasket 3 62. The second anti-collision strip 2 61 and the third sealing gasket 3 62 are also vertically arranged on the door panel 2 and arranged along the height direction of the door panel 2. The two door panels 2 squeeze the sealing unit 3 6 to achieve the gap sealing.

[0055] Both door panels 2 are equipped with anti-collision strips 2 61 and sealing gaskets 3 62, indicating that sealing unit 3 6 contains two anti-collision strips 2 61 and two sealing gaskets 3 62. One anti-collision strip 2 61 and one sealing gasket 3 62 constitute a set of seals, located at the rear end of the gap. Sealing unit 3 6 has two sets of seals; the other set is located at the front end of the gap, as shown below. Figure 9 and Figure 10 As shown.

[0056] Anti-collision strip 261 and anti-collision strip 151 are made of the same material and have the same structure. Anti-collision strip 261 is a solid strip structure made of elastic rubber. Anti-collision strip 261 is vertically bonded to the thickness surface 8 of the two door panels 2. The two anti-collision strips 261 are arranged at both ends of the straight gap, so that it can play a buffering role no matter which door panel 2 closes first. Two sealing gaskets 362 are arranged between the two anti-collision strips 261. The anti-collision strips 261 and the sealing gaskets 362 are attached to each other. The two sealing gaskets 362 in the middle of the gap are tightly attached, and the joint surface is a continuous wavy surface, which can increase the sealing performance of the joint.

[0057] Anti-collision strip 2 61, sealing gasket 3 62, sealing gasket 3 62 and anti-collision strip 2 61 are arranged in sequence in the straight gap. The four fill the gap to achieve effective sealing. No matter which side of the door panel 2 fails the seal, the seal on the other side of the door panel 2 can still seal the gap, which has a dual protection and sealing function.

[0058] Finally, sealing gasket 1 42, sealing gasket 2 52 and sealing gasket 3 62 are not conventional sealing gasket structures. Each of these three gaskets has an absorbent strip 17 embedded in it. Thus, each gasket not only plays a sealing role, but also absorbs any small amount of water that seeps in, preventing the water from continuing to seep into the room.

[0059] To facilitate the installation of the water-absorbing strip 17, dovetail-shaped water-absorbing grooves 16 are provided on one side of sealing gasket 1 42, sealing gasket 2 52, and sealing gasket 3 62. Since sealing gasket 1 42 is wider, there are two water-absorbing grooves 16 inside sealing gasket 1 42. The side with the water-absorbing grooves 16 refers to the side that is not coated with adhesive and is not fixed. When the door panel 2 is closed, it can be squeezed to fit tightly against it, and when it is opened, it can be separated from this side.

[0060] Absorbent strips 17, which are water-absorbing sponge strips, are arranged inside the absorbent groove 16. The dovetail-shaped absorbent groove 16 secures the absorbent strips 17, facilitating their installation and removal while maintaining their proper posture. Even after absorbing water, the absorbent strips 17 remain within the absorbent groove 16 and will not detach due to gravity once saturated. After rain, the absorbent strips 17 can be observed for water absorption. Depending on the amount of water absorbed, they can be removed for cleaning, and then repositioned into the absorbent groove 16 for secure fixation.

[0061] This invention involves arranging a sealing unit 4 in the gap between the door panel 2 and the door frame 1 to ensure the airtightness between them; arranging a sealing unit 5 in the gap between the two door panels 2 of each double door to ensure the airtightness of each double door itself; and arranging a sealing unit 6 in the gap between the two adjacent door panels 2 of two adjacent double doors to increase the airtightness between adjacent double doors. Each sealing unit has the functions of anti-collision buffering, waterproof sealing, and environmental isolation. The three sealing units can achieve effective sealing of double doors or windows from multiple directions, improving the waterproof sealing, sound insulation, and heat insulation performance of double doors or windows, and ensuring that the interior building is not harmed by the external environment.
