Abstract

This invention discloses a high sound insulation swing door, in which a sealing structure is installed at the door frame stop. The sealing structure includes a support part, a side sealing part, an anti-collision sealing part, and a fixing part. The free end of the support part is connected to the side sealing part. The fixing part is located between the positioning end of the support part and the anti-collision sealing part. The fixing part is installed at the stop edge of the door frame stop. The right angle edges of the door panel side wall and the door panel outer wall are chamfered or the two side walls of the door panel are inclined inward towards the closing direction. The side sealing part corresponds to the door panel side wall, and the anti-collision sealing part corresponds to the door panel outer wall. When the door panel is closed, the anti-collision sealing part is flattened, which drives the side sealing part to move towards the door panel side wall, thereby achieving a double seal between the door panel and the sealing structure.

Description

Technical Field

[0001] This invention relates to a high sound insulation swing door. Background Technology

[0002] The primary function of traditional hinged door soundproofing strips is to reduce the hard impact noise when the door closes, while also providing some sound insulation through sealing. However, because the door panels are usually slightly misaligned and not perfectly flat, in most cases, a complete fit between the door panel and the soundproofing strip cannot be guaranteed, resulting in a reduction in sealing and sound insulation performance.

[0003] Conventional interior decorative doors, on the one hand, are frequently opened and closed and are relatively large in size. Considering the use by the elderly and children, the force required to push and pull the door leaf cannot be too great. On the other hand, from the perspectives of aesthetics, cleanliness, and even cost, the shape of the side of the door leaf should not be complicated, so sealing methods similar to those used for aluminum profile doors and windows are not convenient to use.

[0004] Existing soundproof doors on the market incorporate magnetic strips in the sealing strips and on the door panel, allowing the strips to adhere to the door panel when closed, thus improving the sealing effect. However, this method offers limited improvement in sound insulation and may fail if the door panel deforms or tilts. It also has some impact on the door panel's appearance. Summary of the Invention

[0005] The purpose of this invention is to provide a high-sound-insulation swing door that greatly improves the sealing and sound insulation effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high sound insulation swing door has a sealing structure installed at the door frame stop. The sealing structure includes a support part, a side sealing part, an anti-collision sealing part, and a fixing part. The free end of the support part is connected to the side sealing part. The fixing part is located between the positioning end of the support part and the anti-collision sealing part. The fixing part is installed at the stop edge of the door frame stop. The right angle edges of the door panel side wall and the door panel outer wall are chamfered or the two side walls of the door panel are inclined inward towards the closing direction. The side sealing part corresponds to the door panel side wall, and the anti-collision sealing part corresponds to the door panel outer wall. When the door panel is closed, the anti-collision sealing part is flattened, which drives the side sealing part to move towards the door panel side wall, thereby achieving a double seal between the door panel and the sealing structure.

[0008] A bottom sealing structure is installed at the bottom of the door panel. The bottom sealing structure includes a fixed profile, a movable profile, a bottom door rubber strip, an elastic element, and a stop block. The fixed profile is fixed in a groove at the bottom of the door panel. The upper end of the movable profile is hinged to the fixed profile, and the lower end of the movable profile is connected to the lower end of the fixed profile to the bottom door rubber strip. An elastic element is set between the fixed profile and the movable profile. A lever is set at each end of the movable profile. The lever corresponds to the stop block. The elastic element keeps the bottom door rubber strip open and away from the ground without pressure. When the door is closed, the stop block presses the lever towards the center of the door panel. The lever drives the movable profile to rotate downward. Correspondingly, the bottom door rubber strip also curves downward and touches the ground, thereby sealing the gap at the bottom of the door panel.

[0009] The fixing profile is made of aluminum alloy and includes an L-shaped plate. The L-shaped plate is correspondingly fixed to the top wall and inner side wall of the groove on the bottom wall of the door panel. The side plate of the L-shaped plate is provided with an upper hinge horizontal groove, a receiving groove A and a lower mounting strip groove A. The upper hinge horizontal groove includes an arc-shaped groove and a flared opening. The lower mounting strip groove A is vertical.

[0010] The movable profile is made of aluminum alloy and includes a support part and a hinge part. The hinge part includes an arc-shaped large end and a flat plate section. The arc-shaped large end is rotatably located in the arc-shaped groove. The flat plate section extends through a flared slot and connects to the upper end of the support part. The support part has a receiving groove B corresponding to the receiving groove A and a lower mounting strip groove B corresponding to the lower mounting strip groove. The receiving groove A is lower than the receiving groove B. An elastic element is provided between the receiving groove A and the receiving groove B. The two ends of the door bottom rubber strip are correspondingly installed between the lower mounting strip groove A and the lower mounting strip groove B. Mounting holes are protruding on the side surface of the support part away from the side plate of the fixed profile. The two ends of the mounting holes are inserted into the lever.

[0011] The support part is T-shaped and includes a longitudinal oblique section and an inner transverse oblique section. The side sealing part is arc-shaped. The free end of the longitudinal oblique section is connected to one end of the side sealing part, and its other end is spaced apart from the longitudinal oblique section. The anti-collision sealing part and the fixing part are integrally formed. The fixing part is attached to the stop edge of the door frame stop. The anti-collision sealing part is arc-shaped, and the free end of the anti-collision sealing part is combined with the inner transverse oblique section.

[0012] The support part is F-shaped and includes a longitudinal oblique section, an inner transverse oblique section, and the fixing part. The insert part of the fixing part is inserted into the groove of the stop edge of the door frame. The side sealing part is arc-shaped. The free end of the longitudinal oblique section is connected to one end of the side sealing part, and its other end is spaced apart from the longitudinal oblique section. The anti-collision sealing part is arc-shaped. One end is connected to the free end of the fixing part, and the other end is connected to the free end of the inner transverse oblique section. When the anti-collision sealing part near the fixing part is not under pressure, there is a gap between it and the stop edge of the door frame.

[0013] The support portion is a rigid elastic copolymer, while the side sealing portion and the anti-collision sealing portion are soft elastic copolymers.

[0014] A reverse rounded arc structure is provided at the corner where the longitudinal oblique section meets the fixed part.

[0015] The beneficial effects of this invention are as follows: This invention has a better sealing and sound insulation effect. Typically, the gap between the side of the door panel and the door frame stop is much smaller than the deformation of the door panel surface, resulting in smaller installation and usage errors. Therefore, the reliability of the side seal is greater than the seal between the outer ring of the door panel and the door frame stop. When the door panel is closed, the anti-collision seal is flattened, causing the side seal to move towards the side of the door panel, thus achieving a double seal between the door panel and the sealing structure. Ideally, the double seal between the door panel and the door frame stop will significantly increase the sound insulation effect. Simultaneously, because the pressure of the side seal is perpendicular to the direction of opening and closing the door during the closing process, improving the sealing performance does not increase the pushing and pulling force of opening and closing the door. Its bottom seal structure is simple and low-cost, and because it is a double-sided positive compression, there is no risk of deformation or failure. Attached Figure Description

[0035] The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention.

[0036] like Figure 1 , Figure 2 and Figure 5As shown, this is a first embodiment of a high sound insulation swing door of the present invention. The right-angle edges of the side wall and the outer wall of the door panel are cut with chamfered edges 10A. A sealing structure 1 is installed at the door frame stop. The sealing structure 1 includes a support part 11, a side sealing part 12, an anti-collision sealing part 13, and a fixing part 131. The support part is a rigid elastic copolymer, and the side sealing part and the anti-collision sealing part are soft elastic copolymers. The support portion 11 is T-shaped, including a longitudinal oblique section 111 and an inner transverse oblique section 112. The inner transverse oblique section is spaced apart from the fixing portion, and its free end is inclined away from the fixing portion. The side sealing portion 12 is an arc-shaped sealing strip. The free end of the longitudinal oblique section 111 is connected to one end of the arc-shaped sealing strip. After the arc-shaped sealing strip is folded back, its other end faces the longitudinal oblique section 111 at a distance. The anti-collision sealing portion 13 includes a fixing portion 131 and a sealing section 132. The fixing portion 131 is fixed to the stop edge 20A of the door frame stop with double-sided adhesive. The free end of the sealing section 132 is curved and then combined with the inner transverse oblique section 112. The side sealing portion corresponds to the side wall of the door panel, and the sealing section of the anti-collision sealing portion corresponds to the outer wall of the door panel. When the door panel is closed, the sealing section is flattened, causing the side sealing portion to move towards the side wall of the door panel, thereby achieving a double seal between the door panel and the sealing structure. The hinge and latch remain outside the sealing structure. In order to meet the structural size requirements of the sealing structure and to ensure that the sealing structure has sufficient deformation space under pressure, the gap between the door panel and the door frame stop is larger than the conventional gap.

[0037] like Figures 3 to 5 As shown, this is the second embodiment of the present invention. The difference between this embodiment and the first embodiment lies in the structure of the door panel. In the second embodiment, the two side walls of the door panel are inclined in the closing direction, that is, the side walls of the door panel are inclined surfaces 10B.

[0038] like Figure 6 , Figure 7 and Figure 10As shown, this is a third embodiment of the high sound insulation swing door of the present invention. The right-angle edges of the side wall and outer wall of the door panel are cut with chamfered edges 10C. A sealing structure 1A is installed at the door frame stop. This sealing structure 1 includes a support part 11A, a side sealing part 12A, an anti-collision sealing part 13A, and a fixing part 11A3. The support part is a rigid elastic copolymer, while the side sealing part and the anti-collision sealing part are soft elastic copolymers. The support part 11A is F-shaped, including a longitudinal oblique section 11A1, an inner horizontal oblique section 11A2, and the fixing part 11A3. The thickness of each part of the support part 11A is relatively thin, preferably 0.7-1mm. A reverse rounded arc structure 14A is provided at the corner where the longitudinal oblique section and the inner horizontal horizontal section meet, i.e., a flexible structure is added at the corner so that it can obtain the necessary deformation under pressure. The fixing part 11A3 has a latching part 11A4 connected to the stop edge 20 of the door frame stop. The groove of B; the side sealing part 12A is an arc-shaped sealing strip, the free end of the longitudinal oblique section 11A1 is connected to one end of the arc-shaped sealing strip, the other end of the arc-shaped sealing strip is folded back and spaced apart from the longitudinal oblique section, the anti-collision sealing part 13A is arc-shaped, one end is connected to the free end of the fixing part, the other end is folded back and connected to the free end of the inner horizontal oblique section, the anti-collision sealing part 13A near the door frame stop has a gap with the stop edge of the door frame stop when not under pressure. When the door panel is closed, the anti-collision sealing part is flattened, which drives the side sealing part to move towards the side wall of the door panel, thereby realizing a double seal between the door panel and the sealing structure. The hinge and the lock tongue are kept outside the sealing structure. In order to meet the structural size requirements of the sealing structure and to give the sealing structure sufficient deformation space when under pressure, the gap between the door panel and the door frame stop is larger than the conventional gap.

[0039] like Figures 8 to 10 As shown, this is the fourth embodiment of the present invention. The difference between this embodiment and the third embodiment lies in the structure of the door panel. In this embodiment, the two side walls of the door panel are inclined inward in the closing direction, that is, the side walls of the door panel are inclined surfaces 10D.

[0040] like Figures 11 to 16As shown, this is the fifth embodiment of the high sound insulation swing door of the present invention. Based on the third embodiment, a bottom sealing structure 2 is installed at the bottom of the door panel, including a fixed profile 21, a movable profile 22, a bottom door rubber strip 23, an elastic element 24, and a stop block 25. The fixed profile 21 is fixed in a groove 10E at the bottom of the door panel. The groove is a continuous groove located in the middle of the bottom wall of the door panel. The fixed profile 21 is made of aluminum alloy and includes an L-shaped plate 211. The L-shaped plate 211 is correspondingly fixed to the top wall and inner side wall of the bottom groove of the door panel. The side plate of the L-shaped plate 211 has an upper hinge horizontal groove 2111, a receiving groove A2112, and a lower mounting rubber strip groove A2113. The upper hinge horizontal groove includes an arc-shaped groove and a flared opening. The lower mounting rubber strip groove A2113 is vertical. The movable profile 22 is made of aluminum alloy and includes an integrally formed support portion 221 and a hinge portion 222. The support portion 221 and the hinge portion 222 are at an obtuse angle. The hinge portion 222 includes an arc-shaped large end 2221 and a flat plate segment 2222. The arc-shaped large end 2221 is rotatably located in the arc-shaped groove. The flat plate segment 2222 extends through a flared slot and connects with the upper end of the support portion 221. The support portion 221 is provided with a receiving groove B2211 corresponding to the receiving groove A2112 and a lower mounting groove. The lower mounting groove B2212 corresponds to the gluing groove. The receiving groove A is lower than the receiving groove B. An elastic element, preferably a serpentine spring, is provided between the receiving groove A and the receiving groove B. The two ends of the bottom door rubber strip 23 are correspondingly installed between the lower mounting groove A2113 and the lower mounting groove B2212. A mounting hole 223 is provided on the side surface of the side plate away from the fixed profile 21 of the support part 221. A lever 26 is inserted into each end of the mounting hole 223. A stop block 25 corresponding to the lever 26 is installed at the door frame stop. The serpentine spring keeps the bottom door rubber strip open and away from the ground in an uncompressed state. When the door is closed, the stop block presses the lever towards the center of the door panel. The lever drives the movable profile to rotate downward, and the bottom door rubber strip also curves downward and touches the ground, thereby sealing the gap at the bottom of the door panel.

[0041] Preferably, the groove 10E at the bottom of the door panel has a small notch 10F on the side wall end face facing the closing direction, so that the stop 25 installed at the door frame stop can press the lever 26. The lever 26 on the hinge side has a chamfer cut on the surface corresponding to the stop.

[0042] The sealing structure of this invention is a soft and hard co-extruded adhesive strip. This process is further divided into two types: one is to use a soft and hard elastic copolymer, which is extruded separately in two sets of molds and thermally synthesized into one piece before it is cured at high temperature immediately after extrusion; the other is to use a hard elastic copolymer as a skeleton, with a coating layer bonded to the exposed surface, and the cavity filled with foamed polyurethane.

[0043] The sealing effect of the door panel sidewall (achieved by the side sealing part) of this invention is better and more reliable than the sealing effect of the door panel outer wall (achieved by the anti-collision sealing part). In fact, the main reason why conventional sealing strips have poor sound insulation is that there are gaps in the partially fitted parts. The core effect of this double seal is that it first ensures that the longitudinal seal is basically fully fitted, while the fitted part of the transverse seal achieves a double-layer seal, which greatly improves the sound insulation effect; even the unfit parts are better than those without side seals because the side seals are already effective and the gaps are small, and they are also air gap channels at bends.

[0044] The top and side gaps of a conventional hinged door are 3mm, while the sealing structure used in this invention requires a slightly larger gap (4~5.5mm). This is to provide structural space for the sealing structure, and also to ensure that even if the door panel is chipped at a corner (due to loosening of the hinge installation part during use) or there are installation errors, the side rubber strip will not come into contact with the door leaf before it is deformed under pressure in the initial stage of closing, thereby reducing the pushing and pulling force when opening and closing the door.
