Abstract
Description
Technical Field
[0001] This invention relates to the field of door and window technology, specifically to an accessible swing door. Background Technology
[0002] Traditional electric swing doors mostly use a hinged rotating structure. When opening, the door swings outward from the front of the passageway, occupying passage space. The wider the passageway and the larger the door, the greater the swing amplitude, and the stronger the interference with passage. At the same time, in traditional structures, the drive arm and hinge are not on the same axis, resulting in obvious drag during the opening and closing process. This leads to high operating noise, easy door deformation, and high maintenance costs, making it difficult to meet the requirements of hospitals, elderly care buildings, and high-end office buildings for accessibility, low noise, and high reliability.
[0003] Existing track-mounted swing doors generally suffer from unreasonable track layout, severe motion interference, and poor coordination between the slider and the track, making it difficult to achieve truly barrier-free and low-drag operation. Therefore, there is an urgent need for a barrier-free swing door that is simple in structure, moves smoothly, has no drag, and does not occupy passageway space. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: An accessible swing door according to an embodiment of the present invention includes a door body, a drive device, and a track system; The track system includes a main track and a side track, with the main track and the side track fixedly installed at the top of the door frame at an angle of 85° to 160° to each other. A first hanging pulley and a second hanging pulley are fixedly installed on the top two sides of the door body, respectively. The first hanging pulley is slidably engaged with the main track, and the second hanging pulley is slidably engaged with the side track. A sliding groove is fixedly provided on the top of the door body between the first hanging pulley and the second hanging pulley, and a slider is slidably connected in the sliding groove. The driving device includes a driving shaft and a transmission arm. The driving shaft is located near the junction of the main track and the side track. One end of the transmission arm is fixedly connected to the driving shaft, and the other end is hinged to the slider.
[0005] Furthermore, the driving device is a motor drive system, which drives the drive shaft to rotate, and drives the slider to move along the slide groove through the transmission arm, thereby causing the first hanging pulley to slide along the main track and the second hanging pulley to slide along the side track, so as to realize the opening and closing of the door.
[0006] Furthermore, the angle between the main track and the side track is 90°, which is the standard installation state; or it is 85°~90° / 90°~160°, which is a special installation state.
[0007] Furthermore, the slider is provided with a connector, which is connected to the slider through a fixing hole on the slider; the connector is provided with an 8mm freely rotatable bolt, and the slider is detachably connected to the transmission arm through the bolt, and the slider can rotate freely around the bolt.
[0008] Furthermore, the drive device also includes a motor and a reduction mechanism, wherein the motor is connected to the drive shaft via the reduction mechanism.
[0009] Furthermore, when the door is in the closed state, the first hanging pulley is located in the middle of the main track, and the second hanging pulley is located at the end of the side track closer to the main track; when the door is in the open state, the first hanging pulley is located at the end of the main track closer to the side track, and the second hanging pulley is located at the end of the side track away from the main track.
[0010] Furthermore, the present invention includes two symmetrically arranged door bodies, two sets of driving devices, and two sets of track systems, forming a double-opening barrier-free electric swing door.
[0011] The advantages of this invention compared to the prior art are: 1. The door adopts a combination of a main track and a side track at an angle, with double hanging pulleys, so that the door body can avoid obstructing passage space and truly achieve barrier-free passage; 2. By driving the rotating shaft, transmission arm, slider and slide rail in linkage, the opening and closing process is that the pulley slides smoothly on the track, with low friction, no drag, smooth operation and low noise; 3. The track angle can be adjusted within the range of 85°~160°, with a standard of 90°, adapting to different on-site installation conditions and possessing strong versatility; 4. Simple structure and modular design, the slider and transmission arm are detachably connected, which makes installation and maintenance convenient, with high reliability, long service life and low maintenance cost; 5. It can be opened individually or in pairs, and has a wide range of applications, especially suitable for hospitals, elderly care buildings, high-end office buildings, clubs and other places.
