Description

Technical Field

[0001] This utility model relates to the technical field of door and window hardware, and in particular to a track-off offset load-bearing structure and a folding door and window. Background Technology

[0002] Folding doors are a popular type of door on the market. They combine the advantages of hinged doors (large opening area for ventilation) with the smaller opening space required by sliding doors, making them favored by many consumers. However, most common folding door structures on the market are either non-insulated or double-track insulated. The disadvantage of non-insulated structures is their limited applicability, making them unsuitable for areas with high insulation requirements. Therefore, to address the insulation issue, the industry has developed a double-track insulated folding door structure, such as... Figure 1 As shown, it includes fan body profile 11, upper heat insulation strip 12, frame profile 13, lower heat insulation strip 14 and sliding wheel 15. However, its drawback is that if the width of the heat insulation strip is changed, the lower sliding wheel hardware cannot be universally used. The lower sliding wheel hardware needs to be redeveloped, which is extremely costly and increases inventory pressure. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a track offset load-bearing structure.

For those skilled in the art, the specific meaning of the terms in this utility model can be understood according to the specific circumstances.

[0023] This embodiment discloses a folding door and window, including a sash, a frame, and a track-off load-bearing structure.

[0024] Specifically, see Figure 2 The track-offset load-bearing structure includes a fan-shaped profile 21, a frame profile 22, a sliding wheel 23, and a track component 24. The fan-shaped profile 21 includes a first fan-shaped profile 211, a second fan-shaped profile 212, and a first spacer 213, with the first spacer 213 located between the first fan-shaped profile 211 and the second fan-shaped profile 212. The frame profile 22 includes a first frame profile 221, a second frame profile 222, and a second spacer 223, with the second spacer 223 located between the first frame profile 221 and the second frame profile 222. The sliding wheel 23 is connected to the bottom of the first fan-shaped profile 211. The track component 24 is laid on the bottom of the first frame profile 221 and is offset from the second spacer 223 in the horizontal direction to support the sliding wheel 23.

[0025] Compared to existing technologies, the track offset load-bearing structure of this solution places the pulley 23 between the first fan profile 211 and the first frame profile 221, avoiding mutual interference between the pulley and the first spacer 213 or the second spacer 223. This ensures that when the width of the first spacer 213 or the second spacer 223 needs to be changed, there is no need to redevelop the pulley hardware, fan profile or frame profile, saving costs and avoiding inventory backlog.

[0026] In this embodiment, the track offset load-bearing structure further includes an anti-derailment plate 25, which is connected to the lower pulley 23. An anti-derailment groove 2211 is provided within the first frame profile 221, and the anti-derailment plate 25 is used to extend into the anti-derailment groove 2211 to limit the sliding trajectory of the lower pulley 23. It is understood that the anti-derailment plate 25 prevents the pulley from slipping off the track component 24.

[0027] In this embodiment, the lower pulley 23 includes a pulley frame and a roller. The roller is rotatably connected to the pulley frame, and the pulley frame is connected to the first profile 211. The pulley frame is fixed inside the first profile 211 and rotatably connected to the roller, which rolls within the track member 24.

[0028] Specifically, the anti-derailment plate 25 is connected to the pulley frame. The anti-derailment plate 25 moves synchronously with the pulley frame but does not rotate, thus stably preventing the pulley from derailing.

[0029] In this embodiment, the lower pulley 23 is located on the bottom inner side of the first profile 211. Specifically, the pulley bracket is located on the bottom inner side of the first profile 211. Positioning the lower pulley 23 on the bottom inner side of the profile avoids exposed hardware, improving aesthetics, and also prevents interference between the hardware and the profile in folding doors and windows.

[0030] In this embodiment, the first profile 211 is the outer frame profile, the second profile 212 is the inner frame profile, and the first spacer 213 is the first thermal insulation strip. The first frame profile 221 is the outer frame profile, the second frame profile 222 is the inner frame profile, and the second spacer 223 is the second thermal insulation strip. It should be noted that the first spacer 213 and the second spacer 223 can be thermal insulation strips, sound insulation strips, sealing strips, etc., and different functions and different widths of spacer materials and structures can be selected according to different environmental requirements.

[0031] In this embodiment, the track offset load-bearing structure also includes an upper pulley (not shown in the figure), which is located on the top of the first fan profile 211 and is used to slide on the first frame profile 221 to prevent the fan body from tilting. The upper pulley is used to cooperate with the lower pulley 23 to stably install the fan body in the frame and prevent the fan body from tilting during sliding.

[0032] In another embodiment, the track offset load-bearing structure further includes an upper pulley located on the top of the second fan profile 212 for sliding on the second frame profile 222 to prevent the fan body from tilting.

[0033] The upper pulley and the lower pulley 23 can both be located on the inner side of the fan body, or the lower pulley 23 can be located on the inner side of the fan body and the upper pulley can be located on the outer side of the fan body, as long as stable support and sliding can be guaranteed.

[0034] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
