Description

Technical Field

[0001] This utility model relates to the field of doors, specifically a lift-type swing door. Background Technology

[0002] A swing door is a fixed structure used to block access to an area. The door leaves are opened and closed by rotating hinges, and when opened, the door leaves move in a fan-shaped trajectory.

[0003] Hinged doors have many applications, but when used in sloping environments, such as entrances and exits of resorts or warehouses, if the door is opened too forcefully downhill, it may push people or small transport vehicles downhill due to inertia. Therefore, it is safer to open the door to the side with the steeper inward slope. However, when a hinged door is opened, the absolute height of the lower edge of the door does not change, but the height of the slope increases continuously. This shortens the horizontal distance between the lower edge of the door and the slope when it is opened, causing interference and affecting the opening of the door. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a lift-type swing door, comprising a hinge assembly and a door leaf mounted on a building structure. The door leaf is connected to the building structure via the hinge assembly. The hinge assembly includes a base hinge at the top and a lower extension hinge at the bottom. Both the base hinge and the extension hinge have ball bearings that rotate around a ball portion within the ball bearings. The line connecting the centers of the balls in the base hinge and the balls in the extension hinge serves as the pivot point of the door leaf. The vertical edge of the door leaf closest to the building structure is designated as the inner edge, while the vertical edge furthest from the building structure is designated as the inner edge. The edge is defined as the outer edge, and the inner edge is used as the side to rotate around the axis, and the trajectory of the rotation forms a rotating body; the rotating body is frustum-shaped and the diameter of the top end is smaller than that of the bottom end, the axis is inclined, the distance between the base hinge at the top of the axis and the building body is smaller than the distance between the extension hinge at the bottom of the axis, and the horizontal height of the bottom surface of the rotating body near the building body is lower than the horizontal height of the end away from the building body; a door opener is provided between the door leaf and the building body, and the two ends of the door opener are movably connected to the door leaf and the building body respectively, and the connection has at least two degrees of freedom.

[0005] Furthermore, both sides of the ball bearings of the base hinge and the extension hinge are provided with adjustment bases, and the adjustment bases on both sides are connected to the door leaf and the building body respectively. The adjustment bases are provided with several through holes for the fasteners to pass through. The base hinges and the extension hinges adjust their installation positions on the door leaf and the building body through the adjustment bases, thereby adjusting the tilt angle between the bottom surface of the rotating body and the horizontal plane.

[0006] Furthermore, the base hinge includes a base sleeve head and a base sleeve seat, the ends of which are fixedly connected to the adjusting base, and the base sleeve head and the base sleeve seat are connected by a ball bearing.

[0007] Furthermore, the booth hinge includes a follower rod and a fixed rod, the ends of which are fixedly connected to the adjustment base. The booth hinge also includes a follower sleeve and a fixed sleeve, the follower sleeve being detachable from the follower rod and the fixed sleeve being detachable from the fixed rod. The follower sleeve and the fixed sleeve are connected by a ball joint bearing.

[0008] Furthermore, the follower sleeve and the follower fixed rod are inclined on the adjusting base and the inclined direction is close to the fixed rod installed on the building body. The side of the building body on which the booth hinge is installed is set as the mounting plane, and the ball bearing in the booth hinge has a projection on the mounting plane.

[0009] Furthermore, the follower sleeve and the follower fixed rod, and the fixed sleeve and the fixed rod are detachably nested together to allow for length adjustment. The follower fixed rod has a groove along its length, and the follower sleeve has a fixing bolt that passes through the groove and is locked and fixed on the other side of the follower sleeve.

[0010] Furthermore, the horizontal height of the bottom edge of the closed door leaf is higher than the horizontal height of the bottom edge of the closed door leaf.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention employs a base hinge and an extension hinge that utilize ball bearings for swinging to install the door leaf. By determining the tilt angle of the shaft between the two ball bearings and the trajectory of the rotating body formed by the inner edge of the door leaf around the shaft, the lifting degree of the door leaf after opening and closing can be determined. Then, one ball bearing is positioned as a reference using a fixed base hinge, and the extension length of the other ball bearing is determined using a movable follower sleeve and a fixed sleeve. The horizontal height of the other ball bearing is determined by adjusting the installation height of the extension hinge. This allows the actual installation to continuously fit the required tilt amplitude of the virtual shaft, thereby achieving an installation position that is approximately or exactly the same as the calculated virtual shaft. Consequently, the door leaf swings to the side and upward when opened, raising the outer edge of the door leaf to avoid slopes, thus adapting to sloping scenarios. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0022] Examples, such as Figures 1-5As shown: This utility model provides a lifting swing door, the structure of which includes a hinge assembly 3 and a door leaf 1 installed on a building body 4. The building body 4 is a structural object fixed to the ground, which can be a common fixed structure such as a brick column or iron column. The door leaf 1 is connected to the building body 4 through the hinge assembly 3, allowing the door leaf 1 to swing on the building body 4 through the hinge assembly 3. The hinge assembly 3 includes a base hinge 31 at the top and a lower extension hinge 32. A door opener 2 is provided between the door leaf 1 and the building body 4, and the two ends of the door opener 2 are respectively connected to the door. The fan 1 and the building body 4 are movably connected and the connection has at least two degrees of freedom, that is, at least two non-parallel rotating shafts A. The base hinge 31 and the extension hinge 32 are provided with ball bearings 33. The ball bearings 33 can be specific bearing products, or they can be ball heads that achieve the bearing effect and matching kits, such as sleeves with corresponding grooves that match the ball heads to form the bearing product style, thereby forming ball bearings 33. The base hinge 31 and the extension hinge 32 both rotate around the ball part 331 provided in the ball bearings 33.

[0023] Among them, the ball bearings 33 of the base hinge 31 and the display hinge 32 are provided with adjustment bases 3a on both sides, and the adjustment bases 3a on both sides are connected to the door leaf 1 and the building body 4 respectively. The adjustment bases 3a are provided with several through holes for the fasteners to pass through.

[0024] For the base hinge 31, the base hinge 31 includes a base sleeve 311 and a base sleeve 312. The ends of the base sleeve 311 and the base sleeve 312 are respectively fixedly connected to the adjusting base 3a. The base sleeve 311 and the base sleeve 312 are connected by a ball bearing 33. In this embodiment, the base hinge 31 is fixedly installed on the door leaf 1 and the building body 4 after installation and does not move. The side of the building body 4 and the door leaf 1 on which the base hinge 31 is installed is set as the installation plane. The ball bearing 33 in the base hinge 31 has a projection on the range of the installation plane. That is, the position of the ball bearing 33 between the base hinges 31 can be on the back of the door leaf 1 and the back of the building body 4. At the same time, it can also be in the outer range of the gap between the door leaf 1 and the building body 4.

[0025] The booth hinge 32 includes a follower rod 321 and a retaining rod 322. The ends of the follower rod 321 and the retaining rod 322 are respectively fixedly connected to the adjusting base 3a. The booth hinge 32 also includes a follower sleeve 323 and a retaining sleeve 324. The follower sleeve 323 is detachable from the follower rod 321, and the retaining sleeve 324 is detachable from the retaining rod 322. The follower sleeve 323 and the retaining sleeve 324 are connected by a ball joint. The bearings 33 are connected, and the follower sleeve 323 and the follower fixed rod 321 are inclined on the adjusting base 3a and the inclined direction is close to the fixed rod 322 installed on the building body 4. The side of the building body 4 where the booth hinge 32 is installed is set as the installation plane. The ball bearing 33 in the booth hinge 32 has a projection on the installation plane. That is, the ball bearing 33 of the booth hinge 32 is located on the back of the building body 4, and does not involve the back of the door leaf 1.

[0026] Furthermore, the follower sleeve 323 and the follower fixed rod 321, and the fixing sleeve 324 and the fixing rod 322 are detachably nested together to allow for length adjustment. The follower fixed rod 321 has a groove along its length, and the follower sleeve 323 has a fixing bolt 325 that passes through the groove and is locked on the other side of the follower sleeve 323. The fixing sleeve 324 and the fixing rod 322 are similarly fixed.

[0027] Thus, the base hinge 31 determines its installation position on the door leaf 1 and the building body 4 by adjustment, and the extension hinge 32 determines its installation position on the door leaf 1 and the building body 4 after being adjusted to a suitable length, thereby adjusting the tilt angle between the bottom surface of the rotating body B and the horizontal plane.

[0028] It should be noted that the line connecting the center of the ball portion 331 in the base hinge 31 and the center of the ball portion 331 in the display hinge 32 serves as the pivot A of the door leaf 1. The vertical edge of the door leaf 1 closer to the building body 4 is designated as the inner edge 1b, and the vertical edge farther from the building body 4 is designated as the outer edge 1a. The door leaf 1 rotates around the pivot A with the inner edge 1b as the edge, and the trajectory of the rotation forms the rotating body B. Both the pivot A and the rotating body B are virtual indicators used to support the trajectory of the specific door leaf 1 structure.

[0029] In this embodiment, it is necessary to achieve that the rotating body B is frustum-shaped and the diameter of the top end is smaller than that of the bottom end, thereby limiting the distance between the ball portion 331 of the bottom mounting hinge 32 and the door leaf 1, so that the pivot A is tilted. Specifically, the distance between the base hinge 31 at the top of the pivot A and the building body 4 is smaller than the distance between the mounting hinge 32 at the bottom of the pivot A, thereby limiting the distance between the ball portion 331 of the bottom mounting hinge 32 and the building body 4. After the pivot A is tilted, the horizontal height of the bottom surface of the rotating body B near the building body 4 is lower than the horizontal height of the end away from the building body 4, so that the outer edge 1a of the door leaf 1 swings upward when the door leaf 1 is opened.

[0030] Furthermore, in this embodiment, the bottom of the inner edge 1b of the closed door leaf 1 is at a higher level than the bottom of the outer edge 1a, thereby increasing the distance between the bottom of the inner edge 1b and the ground when the door leaf 1 is open.

[0031] In summary, in specific implementation, the base sleeve 311 of the base hinge 31 is installed on the door leaf 1 through the adjusting base 3a, and the base sleeve 312 is installed on the building body 4 through the adjusting base 3a. The ball part 331 between the base sleeve 311 and the base sleeve 312 is located between the door leaf 1 and the building body 4. Then, the slope of the ground is determined so that the angle between the formed pivot A and the ground is greater than 90°. That is, a plane perpendicular to the ground is made, and this plane is also perpendicular to the closed door leaf 1. Then, the angle between the projection line of the pivot A on this plane and the ground is greater than 90°. That is, the projection of the bottom surface of the formed rotating body B on this plane has an angle with the ground. After determining the tilt range of the pivot A, the following sleeve 323 and the following fixed rod 321, and the fixed sleeve 324 and the fixed rod are connected. The hinge 322 is locked together by fixing bolt 325. After determining the length of the follower sleeve 323 and the fixed sleeve 324, the horizontal height of the hinge 32 on the door leaf 1 and the building body 4 can be adjusted. By adjusting the length of the extension at both ends and the horizontal height of the installation, the actual installation can be continuously fitted to the required tilt amplitude of the virtual pivot A, so as to achieve an installation position that is approximately or in line with the calculated virtual pivot A. Then, the hinge 32 is installed on the door leaf 1 and the building body 4 by adjusting the base 3a, thus completing the installation of the door leaf 1. Then, the door opener 2 is installed between the door leaf 1 and the building body 4. In this embodiment, an electric cylinder door opener 2 is used. The two ends of the door opener 2 can be connected by hinges, and the swing pivot A of the two hinges is not parallel to each other to achieve two degrees of freedom.

[0032] When the door is opened, the lever arm of the door is retracted by electric power, pulling the door toward the back of the building 4. The door rotates and swings upward by the base hinge 31 and the extension hinge 32, thereby raising the outer edge 1a of the door leaf 1 to adapt to the sloping environment.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
