Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a roller structure and door / window. Background Technology

[0002] Folding doors and windows are a common type of door and window. They are installed between the upper and lower guide rails of the door and window frame. Existing folding doors and windows have rollers installed on the top and / or bottom. The rollers are mounted on the guide rails of the door and window frame and roll on the guide rails when the door and window are pushed or pulled.

The roller frame is movably connected to the connecting frame along a first direction via the first adjustment mechanism, and the roller frame can swing relative to the connecting frame in a swing plane via the second adjustment mechanism. The connecting frame is used to connect with a hinge. When the guide rail is bent, i.e., when the guide rail deforms along the first direction, the roller frame drives the roller to move along the first direction, so that the roller can adapt to the bent guide rail and achieve self-adjustment of the roller. When the guide rail is uneven, i.e., the surface of the guide rail in contact with the roller is convex or concave, the roller frame drives the roller to swing in a swing plane, which is parallel to the radial direction of the roller, so that the roller can adapt to the uneven guide rail and achieve self-adjustment of the roller. It is evident that this roller structure can adjust the position of the roller along the first direction and drive the roller to swing in a swing plane parallel to the second direction, enabling the roller to self-adjust in three-dimensional space. This reduces the probability of problems such as the roller jumping off the track, derailing, and not being able to push or pull smoothly, and provides a guarantee for the smooth movement of the door and window sash connected to the hinge.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] This embodiment provides a roller structure that can adjust the position of the roller along a first direction and drive the roller to swing in a swing plane parallel to a second direction.

[0043] Specifically, such as Figure 1 As shown, the roller structure includes a connecting frame 1, a roller module 3, a first adjustment mechanism, and a second adjustment mechanism. The connecting frame 1 is used to connect with a hinge 2, which is connected to a door / window sash (not shown in the figure). The roller module 3 includes a roller 31 and a roller frame 32. The roller 31 is rotatably connected to the roller frame 32, and the roller 31 is configured to roll on a guide rail (not shown in the figure) of the door / window frame. The axial direction of the roller 31 is a first direction, and the radial direction of the roller 31 is a second direction. Figure 1 For example, the x, y, and z directions are perpendicular to each other. The roller 31 can roll along the x direction on the guide rail. The y direction is the first direction, and both the x and z directions are the second directions. The roller frame 32 is movably connected to the connecting frame 1 along the first direction through the first adjustment mechanism. The roller frame 32 can swing relative to the connecting frame 1 in the swing plane (not shown in the figure) through the second adjustment mechanism. The swing plane is parallel to the second direction. That is, the x and z directions are parallel to the swing plane, and the y direction is perpendicular to the swing plane.

[0044] The roller structure provided in this embodiment includes a first adjustment mechanism and a second adjustment mechanism. The roller frame 32 is movably connected to the connecting frame 1 along a first direction through the first adjustment mechanism, and the roller frame 32 can swing relative to the connecting frame 1 in a swing plane through the second adjustment mechanism. The connecting frame 1 is used to connect with the hinge 2. When the guide rail is bent and not straight, that is, when the guide rail is deformed along the first direction (i.e., the y-direction), the roller frame 32 drives the roller 31 to move along the first direction, so that the roller 31 can adapt to the bent and not straight guide rail, realizing the adaptive adjustment of the roller 31. When the guide rail is uneven, that is, when the surface of the guide rail in contact with the roller 31 is convex or concave (that is, in the z-direction, the guide rail is deformed in the direction toward or away from the roller 31), the roller frame 32 drives the roller 31 to swing in a swing plane, which is parallel to the radial direction of the roller 31, so that the roller 31 can adapt to the uneven guide rail, realizing the adaptive adjustment of the roller 31. It can be seen that the roller structure can adjust the position of the roller 31 along the first direction and drive the roller 31 to swing in a swing plane parallel to the second direction, so that the roller 31 can adaptively adjust in three-dimensional space, reducing the probability of problems such as the roller 31 jumping off the track, derailing, and not pushing and pulling smoothly, and providing a guarantee for the smooth movement of the door and window sash connected to the hinge 2.

[0045] Optionally, such as Figures 1 to 4 As shown, the first adjustment mechanism includes a first assembly hole 41, a support member 42, a protrusion 43, and a limiting part 44. The first assembly hole 41 is formed on the roller frame 32. The support member 42 passes through the first assembly hole 41 and is connected to the connecting frame 1. The wall of the first assembly hole 41 rests on the support member 42. The protrusion 43 protrudes from the connecting frame 1 and is connected to the limiting part 44. The limiting part 44 is located on the side of the roller frame 32 away from the connecting frame 1. In the first direction, the limiting part 44 and the side of the roller frame 32 away from the connecting frame 1 are spaced apart to form a first adjustment gap between the limiting part 44 and the side of the roller frame 32 away from the connecting frame 1. In this structure, the support member 42 passes through the first assembly hole 41 and is connected to the connecting frame 1. The wall of the first assembly hole 41 rests on the support member, thereby realizing the structure of movable connection between the roller frame 32 and the connecting frame 1. The limiting part 44, connected to the protrusion 43, is located on the side of the roller frame 32 away from the connecting frame 1, to limit the roller frame 32 in the first direction and prevent the roller frame 32 from falling off the connecting frame 1. Furthermore, the side of the roller frame 32 away from the connecting frame 1 and the limiting part 44 have a first adjustment gap in the first direction, allowing the roller frame 32 to move relative to the connecting frame 1 in the first direction, thus achieving an adaptive adjustment effect for the roller 31 in the first direction.

[0046] Furthermore, the support member 42 is detachably inserted through the first assembly hole 41, and the support member 42 is detachably connected to the connecting frame 1, thus forming a structure in which the roller frame 32 and the connecting frame 1 are detachably connected. Therefore, the roller module 3 can be assembled with the connecting frame 1 as an independent module. In practical applications, when the roller 31 is damaged and needs replacement, there is no need to replace the connecting frame 1; simply remove the roller module 3 from the connecting frame 1. This not only simplifies the replacement operation of the roller 31 but also reduces maintenance costs. Secondly, the roller module 3 is connected to the connecting frame 1 through the structure of the support member 42 resting on the wall of the first assembly hole 41. This structure is simple and easy to assemble and disassemble, facilitating quick assembly and disassembly of the roller module 3 and the connecting frame 1, thereby improving maintenance and production efficiency. Furthermore, different models of doors and windows often require different models of rollers 31. As an independent module, the roller module 3 does not need to produce multiple models of connecting frames 1 in actual production. Instead, it only needs to produce multiple models of roller modules 3 and ensure that multiple models of roller modules 3 can be connected to the same model of connecting frame 1. It can be seen that this structure eliminates the need to produce multiple models of connecting frames 1 (or even multiple models of hinges 2), which can effectively reduce production costs.

[0047] In other embodiments, the support member 42 can also be fixedly connected to the connecting frame 1, in which case the roller frame 32 and the connecting frame 1 are not detachable. When the support member 42 is fixedly connected to the connecting frame 1, the support member 42 and the connecting frame 1 can be a separate structure or an integral structure, as long as the hole wall of the first assembly hole 41 can overlap the support member 42.

[0048] Furthermore, the support member 42 is a standard part with external threads, such as a bolt or screw, and the connecting frame 1 is provided with a threaded hole. The support member 42 is threadedly engaged with the threaded hole to achieve a detachable connection between the support member 42 and the connecting frame 1.

[0049] In other embodiments, the support member 42 and the connecting frame 1 can also be detachably connected by other structures. For example, the connecting frame 1 is embedded with an iron sheet, and the support member 42 is a strip-shaped magnet, which is magnetically attracted to the iron sheet.

[0050] Optionally, the protrusion 43 is detachably inserted through the first assembly hole 41, and the support 42 is mounted on the protrusion 43, so that the overall structure of the connecting frame 1 and the roller module 3 is more compact.

[0051] Optionally, the connecting frame 1 includes a frame body 11 and a mating part 12. The mating part 12 protrudes from the frame body 11, and the support member 42 is connected to the mating part 12. The second adjustment mechanism includes a first mating surface 51 and a second mating surface 52. The first mating surface 51 is located on the mating part 12, and the second mating surface 52 is located on the roller frame 32. The first mating surface 51 and the second mating surface 52 are at least partially attached and movably connected so that the roller frame 32 can swing relative to the frame body 11 in the swing plane.

[0052] Furthermore, both the first mating surface 51 and the second mating surface 52 are curved surfaces with the same radius of curvature. The directions of the radii of curvature of both surfaces are parallel to the swing plane. The first mating surface 51 and the second mating surface 52 slide together along the curvature direction of the curved surfaces, allowing the roller frame 32 to swing relative to the frame 11 on the swing plane. In addition, this structure ensures that the first mating surface 51 and the second mating surface 52 are in surface-to-surface contact, improving the stability of their sliding contact and thus enhancing the consistency of the swing trajectory of the roller frame 32, reducing the probability of the roller frame 32 and the roller 31 swinging in a non-swing plane.

[0053] It should be noted that the arc length, central angle and radius of the first mating surface 51 and the second mating surface 52 can be determined according to the actual application requirements. For example, the central angle can be 2°, 3°, 3.5° or 4°, etc. The larger the central angle, the greater the swing amplitude of the roller frame 32. In order to expand the swing range of the roller frame 32, it is better to have a central angle greater than 3°.

[0054] In another embodiment, the first mating surface 51 is an arcuate surface protruding towards the second mating surface 52, and the second mating surface 52 is a plane. In this case, the first mating surface 51 and the second mating surface 52 have a line-plane contact relationship. When the roller frame 32 swings, the second mating surface 52 is in contact with the first mating surface 51, and the second mating surface 52 swings along the curvature direction of the first mating surface 51. In yet another embodiment, the first mating surface 51 is a plane, and the second mating surface 52 is an arcuate surface protruding towards the first mating surface 51. In this case, the first mating surface 51 and the second mating surface 52 have a line-plane contact relationship. When the roller frame 32 swings, the second mating surface 52 is in contact with the first mating surface 51, and the second mating surface 52 swings along its own curvature direction.

[0055] Optionally, such as Figure 5As shown, the roller frame 32 includes a first frame plate 321, a second frame plate 322, a frame beam 323, and a rotating shaft 324. The first frame plate 321 and the second frame plate 322 are respectively connected to the two ends of the frame beam 323. The rotating shaft 324 is parallel to the first direction, and the two ends of the rotating shaft 324 are respectively connected to the first frame plate 321 and the second frame plate 322. The roller 31 is rotatably connected to the rotating shaft 324. This structure can improve the reliability of the connection between the roller 31 and the roller frame 32 and avoid the problem of the roller 31 falling off the roller frame 32.

[0056] In this embodiment, the rotating shaft 324 is made of stainless steel, and the roller 31 is a rubber-coated roller. The rotating shaft 324 and the roller 31 are connected by a riveting process.

[0057] Furthermore, the first frame plate 321 and the second frame plate 322 are spaced apart along the first direction. The roller 31 is located between the first clamping plate and the second frame plate 322. The distance between the first frame plate 321 and the second frame plate 322 is 'a', and the dimension of the roller 31 in the first direction is 'b', where 'a' is greater than 'b'. Thus, a second adjustment gap is formed between the roller frame 32 and the roller 31 in the first direction. The roller 31 is slidably sleeved on the rotating shaft 324, allowing the roller 31 to slide relative to its axis along the first direction on the rotating shaft 324. Based on the first adjustment gap between the roller frame 32 and the limiting part 44, the second adjustment gap between the roller 31 and the roller frame 32 not only allows the roller frame 32 to move relative to the frame 11 in the first direction, but also allows the roller 31 to move along the first direction on the roller frame 32. This structure expands the adjustment range of the roller module 3 in the first direction, making the roller structure more suitable for guide rails with a large degree of curvature. Furthermore, the adaptive adjustment of the roller structure in the first direction is distributed across the first adjustment gap and the second adjustment gap, thereby appropriately reducing the size of the first adjustment gap and the second adjustment gap. This achieves the effect of a small movement of the roller frame 32 in the first direction and a small movement of the roller 31 in the first direction, reducing the probability of the roller frame 32 becoming skewed due to an excessively large first adjustment gap, and also reducing the probability of the roller 31 derailing due to an excessively large second adjustment gap.

[0058] Please see Figure 2 The aforementioned skewness of the roller frame 32 refers to the roller frame 32 skewing in the x-direction in a direction toward or away from the frame 11.

[0059] Optionally, such as Figure 2 , Figure 4 and Figure 6As shown, the first frame plate 321 is located on the side of the second frame plate 322 away from the frame body 11. The first assembly hole 41 is formed on the first frame plate 321, and the second frame plate 322 has a second assembly hole 3221. The second mating surface 52 is located on the frame beam 323, and the mating part 12 passes through the second assembly hole 3221 so that the first mating surface 51 and the second mating surface 52 are at least partially in contact. The protrusion 43 protrudes from the mating part 12 on the side away from the frame body 11 and passes through the first assembly hole 41. The limiting part 44 is located on the side of the frame beam 323 away from the second frame plate 322 so that the limiting part 44 plays a limiting role on the roller frame 32. This structure is compact and helps to reduce the overall volume of the roller module 3 and the connecting frame 1, making the roller structure suitable for applications with limited installation space. In another embodiment, the limiting part 44 is located on the side of the first frame plate 321 away from the second frame plate 322, so that the limiting part 44 can limit the roller frame 32.

[0060] Furthermore, the second adjustment mechanism also includes a third mating surface 53. The wall of the second assembly hole 3221 facing the beam 323 is the third mating surface 53. The third mating surface 53 has the same shape as the second mating surface 52, that is, the third mating surface 53 is an arc surface, and the third mating surface 53, the second mating surface 52, and the first mating surface 51 have the same radius of curvature and the same bending direction. Therefore, the first mating surface 51 can not only slide with the second mating surface 52, but also slide with the third mating surface 53. This structure increases the contact area between the first mating surface 51 and the roller frame 32, which has the effect of improving the swing stability of the roller frame 32.

[0061] It should be noted that in this embodiment, both the third mating surface 53 and the first mating surface 51 are curved surfaces, therefore the third mating surface 53 and the first mating surface 51 are in surface-to-surface contact. In other embodiments, the third mating surface 53 and the first mating surface 51 may also be in line-to-surface contact, for example, when the first mating surface 51 is curved and the third mating surface 53 and the second mating surface 52 are both planar; or, when the first mating surface 51 is planar and the third mating surface 53 and the second mating surface 52 are both curved surfaces.

[0062] Optionally, such as Figure 6 and Figure 7 As shown, the second frame plate 322 is provided with a notch 3222, which is directly opposite to the second assembly hole 3221 and communicates with the second assembly hole 3221, so as to avoid the mating part 12 and allow the mating part 12 to pass through the notch 3222.

[0063] The roller structure provided in this embodiment can adaptively adjust the position of the roller 31 in three-dimensional space so that the roller 31 can adapt to uneven or curved guide rails.

[0064] When the guide rail is uneven, since the first mating surface 51 of the connecting frame 1 and the second mating surface 52 of the roller frame 32 are both arc surfaces, and the first mating surface 51 and the second mating surface 52 are mated together, the roller frame 32 can swing relative to the connecting frame 1 in the swing plane to adapt to the uneven guide rail.

[0065] When the guide rail is bent or not straight, on the one hand, the roller frame 32 can move relative to the connecting frame 1 in the first direction. At this time, the second mating surface 52 slides relative to the first mating surface 51 in the first direction. The movement of the roller frame 32 drives the roller 31 to move in the first direction to adapt to the bent or not straight guide rail. On the other hand, the roller 31 can slide on the rotating shaft 324 in the first direction to adapt to the bent or not straight guide rail.

[0066] Of course, in other embodiments, the first and second adjustment mechanisms can also take other forms to achieve adaptive adjustment of the position of the roller 31 in three-dimensional space. For example, the first adjustment mechanism includes a sliding groove and a slider. The groove extends along a first direction and is disposed on the roller frame 32. The slider is connected to the connecting frame 1. When the guide rail is bent, the slider slides in conjunction with the groove to adjust the position of the roller frame 32 and the roller 31 in the first direction, achieving adaptive adjustment of the roller 31. The second adjustment mechanism includes a swing shaft, which is rotatably disposed on the connecting frame 1. The swing shaft is parallel to the first direction, and the end of the slider away from the groove is connected to the outer wall of the swing shaft. When the guide rail is uneven, the swing shaft rotates, allowing the roller frame 32 to swing relative to the connecting frame 1. The swing plane of the roller frame 32 is perpendicular to the first direction, achieving adaptive adjustment of the roller 31. Other structural forms of the first and second adjustment mechanisms will not be listed here.

[0067] This embodiment also provides a door or window, such as Figure 8As shown, the door and window includes a hinge 2, a door / window sash (not shown), a door / window frame 6, and the aforementioned roller structure. The hinge 2 is connected to the door / window sash and also to the connecting frame 1. The door / window frame 6 is provided with a guide rail 612, and rollers 31 are rotatably mounted on the guide rail 612. Using this roller structure, when the guide rail 612 is bent, the roller frame 32 drives the rollers 31 to move along a first direction, achieving adaptive adjustment of the rollers 31 to adapt to the bent guide rail 612. When the guide rail 612 is uneven, the roller frame 32 drives the rollers 31 to swing within a swing plane, which is parallel to the radial direction of the rollers 31, achieving adaptive adjustment of the rollers 31 to adapt to the uneven guide rail 612. This structure enables the roller 31 to self-adjust in three-dimensional space, adapting to both curved and uneven guide rails 612. Consequently, the roller 31 is less likely to skip tracks, derail, or experience uneven pushing and pulling, providing a strong guarantee for the smooth movement of door and window sashes.

[0068] The roller structure provided in this embodiment can be applied to both single-track and multi-track doors and windows. For example, Figure 1 The roller structure shown is suitable for single-track doors and windows. The number of roller modules 3, the first adjustment mechanism, and the second adjustment mechanism are all two or more, and they correspond one-to-one. For example, the number of roller modules 3 can be two, three, or more. Here, two roller modules 3 are used as an example. The two roller modules 3 are distributed along the x-direction; therefore, the rollers 31 in these two roller modules 3 are both rolled on the same guide rail. Of course, if the number of roller modules 3 is one, it is also suitable for single-track doors and windows.

[0069] Multi-track doors and windows can have multiple guide tracks, such as two, three, or even more. Here, we'll take two guide tracks as an example. Figure 1 Taking the coordinate system in the diagram as an example, both guide rails extend along the x-direction and are spaced apart along the y-direction. The number of roller modules 3 is set to two, and the two roller modules 3 are distributed along the y-direction. Each roller module 3 is rolled on its corresponding guide rail.

[0070] Optionally, such as Figures 8 to 10As shown, the door and window frame 6 is provided with a track cavity 61. One inner wall of the track cavity 61 is a mating wall 611. The guide rail 612 is located on the mating wall 611. The roller 31 is provided with a windward side 311 and a leeward side 312. The windward side 311 and the leeward side 312 are arranged opposite to each other along the axial direction of the roller 31. The roller frame 32 is provided with an anti-detachment part 33. The anti-detachment part 33 is located on the side of the windward side 311 away from the leeward side 312. The anti-detachment part 33 is spaced apart from the mating wall 611. The distance between the side of the anti-detachment part 33 facing the mating wall 611 and the mating wall 611 is m. The maximum distance between the side of the guide rail 612 away from the mating wall 611 and the mating wall 611 is n, where m is less than n. When the external environment has wind blowing towards the door and window sash or door and window frame 6, the door and window frame 6 applies pressure to the roller 31 in the same direction as the wind. The windward side 311 of the roller 31 is opposite to the wind direction, that is, the windward side 311 is opposite to the direction of the pressure mentioned above, and along the same direction as the wind, the leeward side 312 is located downstream of the windward side 311.

[0071] When the windward side 311 is subjected to pressure, the roller 31 tends to move from the windward side 311 to the leeward side 312, which can easily lead to the roller 31 detaching from the guide rail 612. The roller frame 32 provided in this embodiment is equipped with an anti-detachment part 33, which is spaced apart from the mating wall 611. The distance between the side of the anti-detachment part 33 facing the mating wall 611 and the mating wall 611 is m, and the maximum distance between the side of the guide rail 612 away from the mating wall 611 and the mating wall 611 is n, where m is less than n. Therefore, when the roller 31 tends to move from the windward side 311 to the leeward side 312, the anti-detachment part 33 can limit the movement of the roller 31, reducing the probability of the roller 31 detaching from the guide rail 612 and providing strong protection for the stability of the fit between the roller 31 and the guide rail 612.

[0072] Furthermore, the anti-detachment part 33 includes a first sub-anti-detachment part 331 and a second sub-anti-detachment part 332. The first sub-anti-detachment part 331 is a generally trapezoidal sheet structure. The first assembly hole 41 has a notch on the side facing the mating wall 611. The first sub-anti-detachment part 331 is connected to the first frame plate 321, and the short side of the first sub-anti-detachment part 331 is sealed at the notch. The distance between the long side of the first sub-anti-detachment part 331 and the mating wall 611 is m. The second sub-anti-detachment part 332 is connected to the side of the first frame plate 321 facing the mating wall 611. That is, the distance between the side of the second sub-anti-detachment part 332 facing the mating wall 611 and the mating wall 611 is m. The first sub-anti-detachment part 331 and the second sub-anti-detachment part 332 can simultaneously limit the movement of the roller 31.

[0073] In other embodiments, the first sub-anti-detachment part 331 can be omitted, and only the second sub-anti-detachment part 332 can be used to limit the roller 31. Alternatively, the second sub-anti-detachment part 332 can be omitted, and only the first sub-anti-detachment part 331 can be used to limit the roller 31.

[0074] In this embodiment, along the direction in which the guide rail 612 protrudes from the mating wall 611, the size of the first frame plate 321 is larger than the size of the second frame plate 322, so that the first frame plate 321 forms a second sub-anti-detachment part 332 on the side facing the mating wall 611. Of course, in other embodiments, the first frame plate 321 may also have a protruding structure on the side facing the mating wall 611 to form the second sub-anti-detachment part 332.

[0075] It should be noted that the term "doors and windows" refers to both doors and windows in general; that is, a door or window can refer to either a door or a window. The term "door and window sash" refers to both door and window sashes; that is, a door or window sash can refer to either a door or a window sash. The term "door and window frame" refers to both door and window frames; that is, a door or window frame can refer to either a door or a window frame.
