Description

Technical Field

[0001] This utility model relates to the field of folding door technology, and in particular to a connecting structure for a hanging body, a folding door, and a folding door system. Background Technology

[0002] Folding doors are sliding doors that can fold multiple door panels together. Because they take up little space when folded and have a large opening space, many residences, hotels, shops, offices and other venues choose to install folding doors.

[0003] For example, Chinese utility model patent with publication number CN213540123U discloses a folding door. In this patent document, the hanging wheel is fixed to the top of the door leaf by the hanging groove assembly. The hanging groove assembly will not slide relative to the door leaf. However, during the folding process of the door leaf, due to installation errors and other reasons, the hanging groove assembly will inevitably be subjected to the squeezing force in the direction perpendicular to the guide rail. After long-term use, the friction between the hanging wheel and the rail will increase, and the folding door will not open or close smoothly. In severe cases, it may even damage the door leaf.

[0029] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0030] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0032] An embodiment of this utility model provides a connection structure for a lifting body, such as... Figure 1 As shown, the device includes a hanging body 100, a connecting seat 200, and a connecting member 300. The connecting member 300 is fixed to the door leaf and is linked to the door leaf. When the connecting seat 200 moves relative to the connecting member 300, the connecting seat 200 also moves relative to the door leaf. The hanging body 100 includes a rotatable pulley 110 to reduce friction, allowing the hanging body 100 to slide along a track. Both the connecting seat 200 and the connecting member 300 are located below the hanging body 100. The hanging body 100 is fixedly connected to the connecting seat 200, thus the hanging body 100 and the connecting seat 200 are linked. When the connecting seat 200 moves relative to the connecting member 300, the hanging body 100 also moves relative to the connecting member 300. The connecting seat 200 and the connecting member 300 are slidably connected.

[0033] When the door is folded, if the connecting seat 200 is subjected to a compressive force in a direction perpendicular to the guide rail, it can adaptively slide relative to the connecting piece 300 to avoid jamming. This reduces the friction between the hanging body 100 and the guide rail, so the folding door can be opened or closed smoothly, and the door and hanging body 100 are not easily damaged, thus extending their service life.

[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, the top surface of the connector 300 is provided with a sliding groove 310, and at least a portion of the connector 200 is embedded in the sliding groove 310 and can slide along the sliding groove 310. The connector 200 can be partially or completely embedded in the sliding groove 310. The side wall of the sliding groove 310 can limit the connector 200, keeping it sliding along the extension direction of the sliding groove 310 and avoiding large deviations in the sliding direction.

[0035] Furthermore, the sliding groove 310 includes a groove bottom 311 and an opening 312 connected to and located above the groove bottom 311. The connecting seat 200 includes a limiting part 210 and a connecting part 220 connected to and located above the limiting part 210. The limiting part 210 is located in the groove bottom 311, and the lower end of the connecting part 220 is located in the opening 312. The width of the opening 312 is smaller than the width of the groove bottom 311. The cross-section of the entire sliding groove 310 can be "L"-shaped or "T"-shaped. The width of the connecting part 220 is smaller than the width of the limiting part 210. Correspondingly, the cross-section of the entire connecting seat 200 can be "L"-shaped or "T"-shaped. The width of the connecting part 220 is smaller than the width of the opening 312 so as not to affect the sliding of the connecting part 220 in the opening 312. The width of the limiting part 210 is smaller than the width of the bottom of the groove 311 so as not to affect the sliding of the limiting part 210 in the bottom of the groove 311. At the same time, the width of the limiting part 210 is greater than the width of the opening 312. The top wall of the bottom of the groove 311 will restrict the limiting part 210 from moving upward out of the bottom of the groove 311, ensuring that the connecting seat 200 and the connecting member 300 maintain a sliding connection.

[0036] Furthermore, the bottom 311 of the groove protrudes from both sides of the opening 312, and the cross-sectional shape of the entire sliding groove 310 is T-shaped. Correspondingly, the limiting part 210 protrudes from both sides of the connecting part 220, and the cross-sectional shape of the entire connecting seat 200 is T-shaped. This structure ensures that both ends of the limiting part 210 are restricted by the top wall of the bottom 311 of the groove. Under force, the entire connecting seat 200 can remain stable, preventing one side from tilting up and affecting the sliding connection between the connecting seat 200 and the connecting member 300.

[0037] In this embodiment, both the limiting part 210 and the connecting part 220 can be block-shaped, and the limiting part 210 and the connecting part 220 can be integrally formed or fixedly connected.

[0038] In other embodiments, a protruding strip may be provided on the top surface of the connector, and a groove adapted to the protruding strip may be provided on the bottom surface of the connector base. The protruding strip is inserted into the groove and can slide along the groove, thereby realizing a sliding connection between the connector base and the connector. Of course, other methods can also be used to realize a sliding connection between the connector base and the connector.

[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, the lifting body 100 includes a pulley seat 120 and a lifting rod 130. The pulley 110 is rotatably connected to the pulley seat 120. The upper end of the lifting rod 130 is fixedly connected to the pulley seat 120, and the lower end of the lifting rod 130 is fixedly connected to the connecting seat 200, thereby fixing the lifting body 100 and the connecting seat 200 together.

[0040] The hanger rod 130 can be a bolt, which passes through the connecting seat 200 from below and is then threadedly connected to the pulley seat 120. Of course, the hanger rod 130 can also be fixedly connected to the pulley seat 120 or the connecting seat 200 by welding or other methods.

[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, the sliding direction of the connector 200 relative to the connector 300 is parallel to the width direction of the door leaf. Due to the limited thickness of the door leaf, the connector 200 has a larger sliding range relative to the width direction of the door leaf compared to the thickness direction, making it easier to install the connector 300.

[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, connector 300 is a base plate, which is suitable for wooden door panels.

[0043] In other embodiments, the connector is a door frame that surrounds the door leaf, which is suitable for aluminum doors.

[0044] In some embodiments, such as Figure 1 As shown, the connector 300 is provided with a through mounting hole 320, and a fastener is inserted through the mounting hole 320. The connector 300 is locked and fixed to the door leaf by the fastener.

[0045] The fastener can be a screw or other fastening device. After the screw passes through the connector 300, it is then fixed into the threaded hole reserved on the door leaf to fix the connector 300 to the door leaf.

[0046] An embodiment of this utility model also provides a folding door, such as... Figure 3 As shown, the connection structure includes the door leaf 400 and the hanging body of any of the above embodiments. For a detailed description of the connection structure of the hanging body, please refer to the above embodiments, which will not be repeated here. The hanging body 100 is located above the door leaf 400 so that the hanging body 100 can slide in the guide rail without the door leaf 400 interfering with the guide rail. The connector 300 is fixed to the top of the door leaf 400.

[0047] In some embodiments, a receiving groove 410 is provided on the top surface of the door leaf 400, the connector 300 is fixed in the receiving groove 410, and the connecting seat 200 is also located in the receiving groove 410. On the one hand, this ensures that neither the connecting seat 200 nor the connector 300 protrudes from the top surface of the door leaf 400, making the top surface of the door leaf 400 relatively flat and reducing the distance between the door leaf 400 and the guide rail. On the other hand, the receiving groove 410 provides dust protection for the connecting seat 200 and the connector 300, making them less susceptible to damage.

[0048] An embodiment of this utility model provides a folding door system, such as... Figure 4 and Figure 5 As shown, the connection structure includes a guide rail 500, multiple door panels 400, several hanging wheels 600, and several hanging bodies of any of the above embodiments. For a detailed description of the connection structure of the hanging bodies, please refer to the above embodiments, which will not be repeated here.

[0049] The guide rail 500 is positioned above the door leaf 400. Both the hanging wheel 600 and the hanging body 100 are slidably engaged with the guide rail 500, and both can slide along the guide rail 500. The door leaves 400 are distributed along the extension direction of the guide rail 500, and adjacent door leaves 400 are rotatably connected. At least one door leaf 400 has a connector 300 fixed to its top, while the tops of the other door leaves 400 are connected to the hanging wheel 600.

[0050] When the entire folding door system needs to be opened, the door leaf 400 moves along the opening direction. During the opening process, two adjacent door leaves 400 rotate relative to each other, and the included angle between them gradually decreases. Finally, multiple door leaves 400 can be folded together. Since at least a portion of the door leaves 400 are fixed with the aforementioned hanging body connection structure, if the connecting seat is subjected to a compressive force in a direction perpendicular to the guide rail 500, it can adaptively slide relative to the connecting piece 300 to avoid jamming. This reduces the friction between the hanging body 100 and the guide rail 500, so the folding door can open or close smoothly, and the door leaves 400 and the hanging body 100 are less likely to be damaged, extending their service life.

[0051] In some embodiments, there are three door panels, one connecting structure for the hanging body, and two hanging wheels. In the closing direction, the top of the middle door panel is fixed with a connector, and the other two door panels are respectively connected to the two hanging wheels.

[0052] In other embodiments, such as Figure 5 As shown, there are four door leaves 400, one connecting structure for the hanging body, and three hanging wheels 600. In the closing direction, the top of the third door leaf 400 is fixed with a connector 300, and the other three door leaves 400 are connected to the three hanging wheels 600 respectively.

[0053] In some other embodiments, there are five door panels, two connecting structures for the hanging body, and three hanging wheels. In the closing direction, the tops of the third and fifth door panels are respectively fixed with connectors of the connecting structures for the hanging body, and the other three door panels are respectively connected to the three hanging wheels.

[0054] Verification has shown that the above three embodiments enable folding doors to open or close smoothly and reduce the number of connection structures required for the hanging body.

[0055] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
