Description

Technical Field

[0001] The utility model belongs to the technical field of doors and windows, and particularly relates to foldable doors and windows. Background Art

[0002] Doors and windows are components in buildings used to separate indoor and outdoor spaces. In addition to the basic functions of windows, they also serve as doors for passage. For example, doors and windows can be installed between a balcony and a living room, thereby separating the balcony from the living room.

[0003] When doors and windows are installed between a balcony and a living room, in some cases, the door panels need to block the intersection to separate the two; in other cases, the door panels need to be released. When the intersection between the balcony and the living room is long, the door panels need to be extended. When the balcony is narrow and there is no space for the door panels to rotate, the door panels can only rotate toward the living room, making it impossible for users to adjust the rotation direction of the door panels according to their needs. In addition, if the door panels are damaged, the replacement cost is high. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide foldable doors and windows to solve the problems in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides a foldable door and window, comprising:

[0006] Door frame, used to connect with the wall;

[0007] The door leaf is provided as at least one and includes at least two blades rotatably connected to each other;

[0008] and guide rails, installed at the bottom of the door frame;

[0009] Among them, in the same door leaf, a single leaf is rotatably mounted on the door frame, and the single leaf is slidably connected to the guide rail through a moving part, the moving part is placed inside the guide rail, and the moving part can be separated from the guide rail;

[0010] When the door leaf is in working state, the width direction of each corresponding blade is parallel to the length direction of the guide rail, and the corresponding blades are arranged in parallel along the length direction of the guide rail; when the door leaf is in non-working state, the width direction of each corresponding blade is perpendicular to the length direction of the guide rail, and the corresponding blades are arranged in parallel along the length direction of the guide rail.

[0011] Through this design, when the door leaf is in a non-working state, different parts of the door leaf (i.e., each blade) can be distributed in parallel along the length of the guide rail, avoiding the door leaf from occupying a large space after being folded, thereby increasing the applicability of the door leaf; in addition, when a single blade is damaged, it can be replaced individually, reducing replacement costs.

[0012] Preferably, the guide rail has a chute with an upward opening, and the moving part is placed in the chute;

[0013] The guide rail is provided with an opening, which communicates with the chute. The opening extends along the length direction of the guide rail and penetrates through both ends of the guide rail along the width direction of the guide rail.

[0014] With such a design, the upward-facing opening is for placing the moving part, and the other two openings can facilitate observing the side parts of the moving part and cleaning the inner area of the guide rail.

[0015] Preferably, there are also two blocking components for blocking the chute; the two blocking components are symmetrically distributed along the width direction of the guide rail;

[0016] Each blocking component includes a supporting part and a blocking part. The supporting part is placed in the chute and used to block the opening of the opening. The blocking part is detachably installed on the supporting part and used to fill at least part of the area of the chute; the blocking part has elasticity to avoid hindering the moving part from moving along the length direction of the guide rail;

[0017] When the moving part moves along the length direction of the guide rail, the part of the blocking part close to the moving part deforms, and the deformed part of the blocking part can automatically reset.

[0018] With such a design, the supporting part blocks the opening of the opening, and the two supporting parts cooperate to block the two openings of the opening to prevent water on the balcony from flowing into the living room; the blocking part is used to fill at least part of the area of the chute to prevent dust and other sundries from easily entering the chute and reduce the frequency of cleaning the chute.

[0019] Preferably, in the same blocking component, the blocking part is set as a single one and extends along the length direction of the guide rail.

[0020] With such a design, compared with the method of setting multiple blocking parts, it can prevent dust and other sundries from entering the chute through the gaps between the blocking parts.

[0021] Preferably, in the same blocking component, the blocking part is set as multiple ones, and each blocking part is arranged in parallel along the length direction of the guide rail.

[0022] With such a design, on the one hand, replacing a single blocking part does not affect the other blocking parts, reducing the replacement cost; on the other hand, the deformation of a single blocking part is not affected by the other blocking parts and is more likely to deform, so as to better ensure the purpose of preventing the blocking part from hindering the moving part from moving along the length direction of the guide rail.

[0023] Preferably, a sealing part is installed on the side of each blocking part away from the adjacent supporting part.

[0024] Through such a design, the sealing part can better prevent sundries such as dust from entering the chute.

[0025] Preferably, along the width direction of the guide rail, a slotted opening is provided at the end of the sealing part away from the adjacent blocking part, and the opening of the slotted opening faces the direction away from the adjacent blocking part corresponding to the sealing part. The slotted opening is arranged through the corresponding sealing part along the length direction of the guide rail;

[0026] Along the length direction of the guide rail, separating parts are provided at both ends of the moving part. The separating parts can be inserted into the slotted openings, and the separating parts are used to prevent the sealing part from hindering the movement of the moving part.

[0027] Through such a design, before the moving part enters between the two sealing parts, the separating parts are inserted into the two slotted openings and urge the two sealing parts to move away from each other, thereby preventing the two sealing parts from hindering the movement of the moving part.

[0028] The beneficial effects of the present utility model: By setting that the door leaf is composed of at least two fan blades that are rotatably connected to each other, when the door leaf is in a non-working state, different parts of the door leaf can be distributed in parallel along the length direction of the guide rail, avoiding the need for the door leaf to occupy a large space after being folded up, and improving the application range of the door leaf; in addition, when a single fan blade is damaged, it can be replaced separately, reducing the replacement cost.

[0047] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0048] Embodiment 1

[0049] As Figures 1 to 8 shown, the present utility model provides a foldable door and window, including:

[0050] A door frame 1 for connecting to a wall;

[0051] A door leaf 2 provided with at least one, including at least two fan blades 21 rotatably connected to each other;

[0052] And a guide rail 3 installed at the bottom end of the door frame 1;

[0053] Wherein, in the same door leaf 2, a single fan blade 21 is rotatably installed on the door frame 1, and a single fan blade 21 is slidably connected to the guide rail 3 through a moving part 4. The moving part 4 is placed inside the guide rail 3, and the moving part 4 can be separated from the guide rail 3;

[0054] When the door leaf 2 is in the working state, the width directions of the respective fan blades 21 are all parallel to the length direction of the guide rail 3, and the respective fan blades 21 are arranged in parallel along the length direction of the guide rail 3; when the door leaf 2 is in the non - working state, the width directions of the respective fan blades 21 are all perpendicular to the length direction of the guide rail 3, and the respective fan blades 21 are arranged in parallel along the length direction of the guide rail 3.

[0055] The composition of the door frame 1 can include various types. For example, in some cases, the longitudinal section of the door frame 1 can be approximately rectangular. In other cases, the door frame 1 can include two side frames and a single bottom frame or top frame. Taking the bottom frame as an example, both ends of the bottom frame are respectively connected to the bottom ends of the two side frames. For the door frame 1, it is a support structure for connecting to the wall, such as being installed at the junction of the balcony and the living room.

[0056] To facilitate the understanding of the door leaf 2, an example is given here as follows: Taking the door leaf 2 as a single one, taking the door leaf 2 including three fan blades 21 as an example, and taking the door frame 1 including a single side frame and a bottom frame as an example; when the door leaf 2 is in the working state, the width directions of the three fan blades 21 are all parallel to the length direction of the guide rail 3, and the three fan blades 21 are arranged in parallel along the length direction of the guide rail 3. Among the three fan blades 21, one of the fan blades 21 is close to the side frame, this fan blade 21 is rotatably connected to the side frame, and one of the other two fan blades 21 is connected to the moving member 4, and adjacent two fan blades 21 are rotatably connected to each other.

[0057] For the guide rail 3, its setting can be adjusted according to the setting of the door frame 1. For example, when the door frame 1 includes a bottom frame and a top frame, the guide rail 3 can be set to two, and the two guide rails 3 are respectively installed on the bottom frame and the top frame, and the moving member 4 is also set to two, and the two moving members 4 are respectively connected to the two guide rails 3; the guide rail 3 can also be set to a single one, and the single guide rail 3 is installed on the bottom frame or the top frame; in some cases, the guide rail 3 can replace the bottom frame.

[0058] For the moving member 4, it can be set as a slider or a roller.

[0059] Optionally, there are entrances and exits on the guide rail 3, and the moving member 4 can leave the inner side of the guide rail 3 through the entrances and exits, so as to facilitate the maintenance and replacement of the moving member 4.

[0060] The dimensions and other characteristics of structures such as the fan blade 21 can be adjusted according to the actual situation. Taking the dimensions of the fan blade 21 as an example, the bottom of the fan blade 21 can be arranged to fit the top of the guide rail 3 or can be arranged at an interval from the top of the guide rail 3.

[0061] By setting the door leaf 2 to be composed of at least two fan blades 21 that are rotatably connected to each other, when the door leaf 2 is in the non - working state, different parts of the door leaf 2 (i.e., the respective fan blades 21) can be distributed in parallel along the length direction of the guide rail 3, avoiding the need for the door leaf 2 to occupy a large space after being retracted, improving the applicable range of the door leaf 2; in addition, when a single fan blade 21 is damaged, it can be replaced separately, reducing the replacement cost.

[0062] The fan blades 21 can be interconnected through specific connecting components (such as hinges, hinges, etc.) to achieve the functions of folding and unfolding. The door leaf 2 is made of various materials, including wood, metal, PVC, glass, etc., to meet different usage requirements and decorative effects.

[0063] When the door leaf 2 is in the working state, the door leaf unfolds and the door and window are closed; when the door leaf 2 is in the non - working state, the door leaf is retracted to the limit and the door and window are opened.

[0064] Embodiment 2

[0065] In this embodiment, the guide rail 3 has a chute 31 with an upward opening, and the moving part 4 is placed in the chute 31;

[0066] The guide rail 3 is provided with an opening 32, the opening 32 is communicated with the chute 31, the opening 32 extends along the length direction of the guide rail 3, and the opening 32 penetrates through both ends of the guide rail 3 along the width direction of the guide rail 3.

[0067] The opening 32 penetrates through both ends of the guide rail 3 along the width direction of the guide rail 3, which makes the opening 32 have three openings. Among them, the upward - facing opening is for placing the moving part 4, and the other two openings can facilitate observing the side parts of the moving part 4 and cleaning the inner area of the guide rail 3, etc.

[0068] Embodiment 3

[0069] In this embodiment, it further includes a plugging assembly 5, which is provided in two and is used to plug the chute 31; the two plugging assemblies 5 are symmetrically distributed along the width direction of the guide rail 3;

[0070] Each plugging assembly 5 includes a supporting part 51 and a plugging part 52. The supporting part 51 is placed in the chute 31 and is used to plug the opening of the opening 32, and the plugging part 52 is detachably installed on the supporting part 51 and is used to fill at least part of the area of the chute 31; the plugging part 52 has elasticity to avoid hindering the movement of the moving part 4 along the length direction of the guide rail 3;

[0071] When the moving part 4 moves along the length direction of the guide rail 3, the part of the plugging part 52 close to the moving part 4 deforms, and the deformed part of the plugging part 52 can automatically reset.

[0072] The blocking component 5 is used to block the sliding groove 31. Among them, the opening 32 is blocked by the supporting part 51, and the two supporting parts 51 cooperate to block the two openings of the opening 32, preventing water on the balcony from flowing into the living room and other situations; the blocking part 52 is used to fill at least part of the area of the sliding groove 31, preventing dust and other sundries from easily entering the sliding groove 31, reducing the frequency of cleaning the sliding groove 31, especially reducing the probability of small sundries such as stones entering the sliding groove 31. When small sundries such as stones enter the sliding groove 31, it is likely to cause situations where the door leaf 2 cannot be fully unfolded and so on.

[0073] For the supporting part 51, it can be connected to the guide rail 3 by means of threaded connection or the like, and no limitation is imposed here.

[0074] The blocking part 52 is elastic. When the moving part 4 moves along the length direction of the guide rail 3, the part of the blocking part 52 close to the moving part 4 deforms, and the deformed part of the blocking part 52 can automatically reset. While achieving the blocking purpose, it avoids the blocking part 52 from hindering the moving part 4 from moving along the length direction of the guide rail 3. The blocking part 52 can be made of elastic materials such as rubber.

[0075] Embodiment 4

[0076] In this embodiment, in the same blocking component 5, the blocking part 52 is set to be single, and the blocking part 52 extends along the length direction of the guide rail 3.

[0077] In this embodiment, the blocking part 52 is set to be single, and the single blocking part 52 extends along the length direction of the guide rail 3. With such a setting, compared with the method of setting multiple blocking parts 52, it can prevent dust and other sundries from entering the sliding groove 31 through the gaps between the blocking parts 52.

[0078] Embodiment 5

[0079] In this embodiment, in the same blocking component 5, the blocking part 52 is set to be multiple, and each blocking part 52 is arranged in parallel along the length direction of the guide rail 3.

[0080] In this embodiment, the blocking part 52 is set to be multiple, and the multiple blocking parts 52 are arranged in parallel along the length direction of the guide rail 3. With such a setting, on the one hand, replacing a single blocking part 52 does not affect the remaining blocking parts 52, reducing the replacement cost; on the other hand, the deformation of a single blocking part 52 is not affected by the remaining blocking parts 52 and is more likely to deform, thus better ensuring the achievement of the purpose of preventing the blocking part 52 from hindering the moving part 4 from moving along the length direction of the guide rail 3. The size and quantity of the blocking part 52 can be adjusted according to the actual situation.

[0081] Embodiment 6

[0082] In this embodiment, a sealing part 6 is installed on one side of each blocking part 52 away from the adjacent supporting part 51.

[0083] Optionally, the sealing portion 6 is provided as a sealing strip.

[0084] The blocking portion 52 is elastic, which can ensure the fitting effect of the two blocking portions 52 to a certain extent. The setting of the sealing portion 6 can better prevent dust and other sundries from entering the chute 31.

[0085] Embodiment 7

[0086] In this embodiment, along the width direction of the guide rail 3, a slot 61 is provided at the end of the sealing portion 6 away from the adjacent blocking portion 52. The opening of the slot 61 faces the direction away from the adjacent blocking portion 52 corresponding to the sealing portion 6, and the slot 61 is arranged along the length direction of the guide rail 3 through the corresponding sealing portion 6.

[0087] Along the length direction of the guide rail 3, separating members 7 are provided at both ends of the moving member 4. The separating members 7 can be inserted into the slots 61, and the separating members 7 are used to prevent the sealing portion 6 from hindering the movement of the moving member 4.

[0088] Along the width direction of the guide rail 3, any one sealing portion 6 has an adjacent sealing portion 6, and these two sealing portions 6 form a group of sealing portions 6. Taking a group of sealing portions 6 as an example, the description is as follows: Before the moving member 4 enters between the two sealing portions 6, the separating members 7 are inserted into the two slots 61 and prompt the two sealing portions 6 to move away from each other, so as to prevent the two sealing portions 6 from hindering the movement of the moving member 4; the setting of the two separating members 7 facilitates the two-way movement of the moving member 4; the setting of the slots 61 not only prevents dust and other sundries from easily entering through the gap between the two sealing portions 6, but also facilitates the separating members 7 to separate the two sealing portions 6.

[0089] Optionally, the cross-section of one end of the separating member 7 is triangular.

[0090] Optionally, magnetic members are provided in the slots 61, and the separating members 7 are magnetic. The magnetic members can be flexible magnets or set as magnetic labels, and the separating members 7 are the same; the separating members 7 and the magnetic members have the same magnetic poles, and the two magnetic members do not have the ability to promote each other's movement due to magnetism and the slots 61, while the separating members 7 can promote the two to move away from each other during the process of approaching the two magnetic members.
