Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a hand-pinch-proof folding door. Background Art

[0002] With the diversification of modern living space design and the improvement of living comfort requirements, folding doors and windows, as a design solution that saves space and provides spacious passage areas, have been widely used in home decoration, especially in open or semi-open areas such as balconies and outdoor living rooms. This type of folding door and window is composed of multiple hinged door leaves. Its unique folding mechanism allows users to easily expand the space when needed, and can be compactly folded when not needed, effectively utilizing limited wall space.

[0003] However, despite the significant advantages of folding doors and windows in terms of functionality and aesthetics, they also expose certain safety hazards during use, especially in home environments involving children or people with limited mobility. Since folding doors are large in size and have flexible folding functions, when the door is in the process of closing or about to close, if someone (especially children) accidentally approaches the opening and closing position of the hardware hinge, it is very easy to get fingers or hands pinched. Such accidents not only cause physical pain to the victims, but may also cause family panic and psychological trauma, posing a potential threat to the safety of family members. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the utility model provides a hand-pinching prevention folding door to avoid the problem of hand-pinching.

[0005] The technical solution adopted by the utility model to solve the problem is:

[0006] A finger-pinch-proof folding door comprises: a door frame, a guide rail being laid in the top frame of the door frame; at least two door leaves; a hinge structure, the hinge structure being assembled on the upper frame and / or the lower frame of two adjacent door leaves; a pulley, the pulley being rotatably connected to at least one door leaf or rotatably connected to the hinge structure, the pulley being slidably arranged in the guide rail so that at least two door leaves can be synchronously folded with each other during the sliding process; wherein an anti-pinch gap is always formed between every two adjacent door leaves during the folding and unfolding process.

[0007] By adopting the above solution, an anti-pinch gap that can accommodate the thickness of an adult's finger is always formed between each two adjacent door leaves during the folding and unfolding process, which is the key to preventing finger pinching accidents. Even if a person or object approaches during the closing process of the door leaf, the risk of being pinched can be effectively avoided due to the existence of the anti-pinch gap.

[0008] Furthermore, the door leaf is equipped with a sealing strip in the direction of the anti-pinch gap, and the sealing strips on every two adjacent door leaves abut against each other when the door leaves are unfolded.

[0009] By adopting the above solution, the anti-pinch gap can be filled by setting a sealing strip, thereby enhancing the sealing performance of the door leaf, further improving the safety and comfort of use, and achieving the effect of blocking wind, dust or rain; secondly, from the perspective of safety, the sealing strip forms a soft buffer layer on the contact surface between the door leaves. Even if a person or object accidentally approaches during the closing process of the door leaf, the elasticity of the sealing strip can also play a certain buffering role, reducing the force of direct collision, thereby further reducing the risk of hand pinching accidents.

[0010] Furthermore, a first assembly profile is arranged between the door leaf and the hinge structure, the first assembly profile is assembled on the side of the door leaf facing the anti-pinch gap, a sealing strip assembly groove is arranged on the first assembly profile, and the sealing strip is assembled in the sealing strip assembly groove.

[0011] By adopting the above solution, not only the structural strength of the door leaf is enhanced, but also a solid foundation is provided for the installation of the sealing strip and the hinge structure.

[0014] Furthermore, a buffer cavity is provided inside the sealing strip to provide a buffer force for the abutting edge.

[0015] By adopting the above solution, sufficient buffer space is provided for the abutting edge when it is subjected to external force, thereby reducing the impact on the abutting edge, reducing the generation of noise and vibration, and also slowing down the movement speed of the door leaf, reducing the force of pinching the hand and avoiding the risk of pinching.

[0016] Furthermore, the door frame also includes two side frames, the side frames are assembled at the ends of the top frame, the side frames are concave toward the door leaf to form a first curved surface, and the sides of the door leaf opposite to the side frames are assembled with a second assembly profile, and the second assembly profile is protruding outwardly with a second curved surface adapted to the first curved surface.

[0017] By adopting the above scheme, the cooperation between the first curved surface and the second curved surface can effectively reduce the gap between the door frame and the door leaf, thereby enhancing the overall sealing performance and reducing the risk of fingers entering. Even if the gap is touched, when the folding door is opened, the finger will be pushed by the second curved surface to avoid being squeezed into the gap between the first curved surface and the second curved surface, thereby greatly improving safety.

[0018] Furthermore, the hinge structure includes: a first hinge seat, the first hinge seat having a first installation cavity; a second hinge seat, the second hinge seat having a second installation cavity; an opening and closing member, one end of the opening and closing member is hinged in the first installation cavity, and the other end is hinged in the second installation cavity, the opening and closing member is used to drive the first hinge seat and the second hinge seat to perform opening or closing movements, when opened, the first hinge seat and the second hinge seat are located in the same straight line, thereby driving two adjacent door leaves to unfold into the same plane, and when closed, the first hinge seat and the second hinge seat are parallel, thereby driving the two adjacent door leaves to fold to be parallel to each other.

[0019] By adopting the above solution, the opening and closing member ensures the flatness and stability of the door leaf when it is opened.

[0020] Furthermore, the opening and closing part includes a first rotating component and a second rotating component, one end of the first rotating component is hinged in the first mounting cavity, and the other end is hinged in the second mounting cavity; one end of the second rotating component is hinged in the second mounting cavity, and the other end is hinged in the first mounting cavity, and the first rotating component is hinged to the middle part of the second rotating component.

[0021] By adopting the above solution, the cross-hinged method enables the two rotating components to cooperate with each other, jointly transmit and convert power, and realize the smooth folding and unfolding of the door leaf.

[0022] Furthermore, the first rotating assembly and the second rotating assembly each include at least two rotating arms, and the rotating arms of the first rotating assembly and the rotating arms of the second rotating assembly are arranged alternately.

[0023] By adopting the above solution, a stable supporting effect can be provided during the folding or unfolding of the door leaf, thereby greatly improving its own strength and service life.

[0024] Furthermore, the hinge structure is also equipped with an abutment member, and the abutment member is used to abut against the door leaf in a closed state.

[0025] By adopting the above solution, additional support and fixation can be provided to ensure that the door leaf can be stably maintained in a closed position, and the door leaf can be prevented from accidentally opening due to wind, vibration or other external factors.

[0026] In summary, the anti-pinch folding door provided by the utility model has the following technical effects:

[0027] 1. By always maintaining an anti-pinch gap between every two adjacent door leaves that can accommodate the thickness of an adult's finger, the risk of pinching fingers when the door leaves are folded or unfolded is effectively avoided. This design provides higher safety protection, especially for children and people with limited mobility.

[0028] 2. The design of folding doors has the advantages of saving space and being easy to unfold and fold. While maintaining these advantages, anti-pinch folding doors also ensure smooth movement between door leaves and the existence of anti-pinch gaps, making it more convenient and safe for users to use without worrying about finger pinching caused by improper operation or unexpected situations.

[0029] 3. Since the anti-pinch folding door is designed to reduce friction and collision between door leaves, it can reduce the risk of wear and damage caused by long-term use. At the same time, the existence of the anti-pinch gap also helps to reduce problems such as door leaf deformation caused by external forces, thereby extending the service life of the folding door.

DETAILED DESCRIPTION

[0040] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the accompanying drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all the examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] In order to facilitate the understanding of the embodiments of the present utility model, the following will be further explained by taking specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present utility model.

[0042] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] Embodiment 1 of the present utility model is referred to Figure 1-Figure 9As shown, a finger-pinch-proof folding door is disclosed, comprising a door frame 1, at least two door leaves 2, a hinge structure 3 and a pulley 4, wherein the door frame 1 comprises a top frame 12 located at the top and two side frames 14 mounted at both ends of the top frame 12, a guide rail 11 is laid in the top frame 12, the hinge structure 3 is mounted on the upper frame and / or the lower frame of two adjacent door leaves 2, the pulley 4 is rotatably connected to at least one door leaf 2 or rotatably connected to the hinge structure 3, and the pulley 4 is slidably arranged in the guide rail 11, so that at least two door leaves 2 can be synchronously folded with each other during the sliding process; wherein, an anti-pinch gap 5 is always formed between every two adjacent door leaves 2 during the folding and unfolding process. It should be noted that the width of the anti-pinch gap 5 is the width of an adult finger and is not less than 1 cm. Therefore, an anti-pinch gap 5 that can accommodate the thickness of an adult finger is always formed between every two adjacent door leaves 2 during the folding and unfolding process. Even if a child or an obstacle approaches during the closing process of the door leaf 2, the risk of being pinched can be effectively avoided due to the existence of the anti-pinch gap 5.

[0045] Specifically, in this embodiment 1, the door leaf 2 is provided with two leaves, and a hinge structure 3 is installed between the top and the bottom of the two door leaves 2, which improves the folding stability of the door leaf 2. The guide rail 11 is arranged in the top frame 12, so the pulley 4 is installed on the upper side of the door leaf 2 that needs to slide.

[0046] In some embodiments, in order to improve the sealing performance between the door leaves 2 and achieve waterproof and dustproof effects, a sealing strip 6 is installed on the door leaf 2 in the direction of the anti-pinch gap 5. The sealing strips 6 on every two adjacent door leaves 2 abut against each other when the door leaf 2 is unfolded. By setting the sealing strip 6, the anti-pinch gap 5 can be filled, the sealing performance of the door leaf 2 is enhanced, and the safety and comfort of use are further improved, and the effect of blocking wind, dust or rain can be achieved; secondly, from the perspective of safety, the sealing strip 6 forms a soft buffer layer on the contact surface between the door leaves 2. Even if a person or object accidentally approaches during the closing process of the door leaf 2, the elasticity of the sealing strip 6 can also play a certain buffering role, reducing the force of direct collision, thereby further reducing the risk of hand pinching accidents.

[0047] In this embodiment 1, a first assembly profile 21 is arranged between the door leaf 2 and the hinge structure 3. The first assembly profile 21 is assembled on the side of the door leaf 2 facing the anti-pinch gap 5. An assembly notch is arranged on the top of the first assembly profile 21, which provides space for the assembly of the hinge structure 3. At the same time, a sealing strip assembly groove 211 is arranged on the first assembly profile 21, and the sealing strip 6 is assembled in the sealing strip assembly groove 211, which enhances the structural strength of the door leaf 2 and provides a solid foundation for the installation of the sealing strip 6 and the hinge structure 3.

[0048] In some embodiments, in order to improve the assembly stability of the sealing strip 6 and facilitate replacement, ribs 212 are provided on both sides of the notch of the sealing strip assembly groove 211. The sealing strip 6 includes a clamping portion 61 and at least one abutting edge 62. The clamping portion 61 is assembled in the sealing strip assembly groove 211 and abuts against the ribs 212. The abutting edge 62 extends out of the sealing strip assembly groove 211. In this embodiment 1, two abutting edges 62 are provided, and the two abutting edges 62 have different heights, which can achieve abutment effects of different pressures, thereby achieving a double sealing effect, ensuring the stability and reliability of the sealing strip 6 after installation, and avoiding the reduction of sealing performance or safety hazards caused by the loosening of the sealing strip 6.

[0049] In order to further improve the anti-pinch ability of the sealing strip 6, a buffer cavity 63 is provided inside the sealing strip 6 to provide a buffer force for the abutting edge 62. First, the buffer cavity 63 provides sufficient buffer space for the abutting edge 62 when it is subjected to external force. When the door leaves 2 are unfolded and abut against each other, the sealing strips 6 on the adjacent door leaves 2 will first contact through the abutting edge 62. In this process, if an external force acts on the door leaf 2, the abutting edge 62 will be subjected to a certain pressure, and the air or elastic material in the buffer cavity 63 can absorb and disperse this part of the pressure, thereby reducing the abutting force. The impact on the joint edge 62 is reduced, and the generation of noise and vibration is reduced; in addition, the buffer cavity 63 also allows the sealing strip 6 to undergo a certain degree of deformation when squeezed, thereby generating a rebound force. When the external force disappears, the sealing strip 6 can quickly return to its original state, preparing for the next sealing and buffering; from a safety perspective, the design of the buffer cavity 63 also further reduces the risk of pinching hands. When a person or object accidentally approaches during the closing process of the door leaf 2, the buffering effect of the sealing strip 6 can slow down the movement speed of the door leaf 2, reduce the force of pinching hands, and avoid the risk of pinching injuries.

[0050] In some embodiments, in order to achieve the function of preventing fingers from being pinched between the side frame and the door leaf 2, a concave first curved surface 141 is provided on the surface of the side frame 14 facing the door leaf 2, and a second assembly profile 22 is provided on the side of the door leaf 2 opposite to the side frame 14. The second assembly profile 22 protrudes outwardly toward one side of the first curved surface 141 when the door leaf 2 is unfolded, forming a second curved surface 221 that matches the first curved surface 141. The mutual cooperation between the first curved surface 141 and the second curved surface 221 can effectively reduce the gap between the door frame 1 and the door leaf 2, thereby enhancing the overall sealing performance and reducing the risk of fingers entering. Even if the finger touches the gap, when the folding door is opened, the finger will be pushed by the second curved surface 221 to avoid squeezing into the gap between the first curved surface 141 and the second curved surface 221, thereby greatly improving safety.

[0051] It should be noted that in this embodiment 1, since at least one side of the two door leaves 2 abuts against the door frame 1 when the door leaves 2 are unfolded, the two door leaves 2 are equipped with the first assembly profile 21 and the second assembly profile 22. When more than three door leaves 2 are provided, the door leaf 2 located in the middle of the edge door leaves 2 only needs to be installed with the first assembly profile 21 on both sides.

[0052] In this embodiment 1, the hinge structure 3 includes a first hinge seat 31, a second hinge seat 32 and an opening and closing member 33. The first hinge seat 31 has a first installation cavity 311, and the second hinge seat 32 has a second installation cavity 321. One end of the opening and closing member 33 is hinged in the first installation cavity 311, and the other end is hinged in the second installation cavity 321. The opening and closing member 33 is used to drive the first hinge seat 31 and the second hinge seat 32 to perform opening or closing movements. When opened, the first hinge seat 31 and the second hinge seat 32 are located in the same straight line, thereby driving the two adjacent door leaves 2 to unfold into the same plane. When closed, the first hinge seat 31 and the second hinge seat 32 are parallel, thereby driving the two adjacent door leaves 2 to fold to be parallel to each other, ensuring the flatness and stability of the door leaves 2 when opened. Specifically, the opening and closing member 33 includes a first rotating component 331 and a second rotating component 332, wherein one end of the first rotating component 331 is hinged in the first mounting cavity 311, and the other end is hinged in the second mounting cavity 321; one end of the second rotating component 332 is hinged in the second mounting cavity 321, and the other end is hinged in the first mounting cavity 311, and the first rotating component 331 is hinged to the middle part of the second rotating component 332.

[0053] In some embodiments, in order to improve the opening and closing texture of the opening and closing member 33, that is, its own strength, the first rotating component 331 and the second rotating component 332 each include at least two rotating arms, and the rotating arms of the first rotating component 331 and the rotating arms of the second rotating component 332 are arranged in an staggered manner, which can provide a stable support effect during the folding or unfolding of the door leaf 2, thereby greatly improving its own strength and service life.

[0054] It should be noted that, in other embodiments, the specific opening and closing method and the opening and closing structure of the hinge structure 3 are not limited, and it is sufficient to retain the anti-pinch gap 5.

[0055] Optionally, in some embodiments, an abutment member 7 may be further assembled on the hinge structure 3, and the abutment member 7 is used to abut against the closed door leaf 2. In the present embodiment 1, the assembled abutment member 7 includes an assembly plate 71 and a baffle 72. When the two doors are folded, the assembly plate 71 extends outward in a direction away from the other door leaf 2, and the baffle 72 is hammer-connected to the extended end of the assembly plate 71, so that the door leaf 2 abuts against the top frame 12 of the door frame 1 when closed, providing additional support and fixation, ensuring that the door leaf 2 can be stably maintained in the closed position, and preventing the door leaf 2 from accidentally opening due to wind, vibration or other external factors.

[0056] In summary, the anti-pinch folding door provided by the utility model has the following technical effects:

[0057] 1. By always maintaining an anti-pinch gap 5 between every two adjacent door leaves 2 that is thick enough to accommodate an adult's finger, the risk of pinching fingers when the door leaves 2 are folded or unfolded is effectively avoided. This design provides higher safety protection, especially for children and people with limited mobility.

[0058] 2. The design of the folding door itself has the advantages of saving space and being easy to unfold and fold. While maintaining these advantages, the anti-pinch folding door also ensures the smooth movement between the door leaves 2 and the existence of the anti-pinch gap 5, making it more convenient and safe for users to use without worrying about the problem of pinching fingers caused by improper operation or unexpected situations.

[0059] 3. Since the anti-pinch folding door is designed to reduce friction and collision between the door leaves 2, it can reduce the risk of wear and damage caused by long-term use. At the same time, the existence of the anti-pinch gap 5 also helps to reduce problems such as deformation of the door leaf 2 caused by external forces, thereby extending the service life of the folding door.

[0060] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
