Description

Technical Field

[0001] The utility model relates to the technical field related to folding door accessories, in particular to a multi-purpose handle for a folding door and a folding door mechanism. Background Art

[0002] A common problem in existing folding door designs is that only a groove-shaped structure is provided on the door body for opening or closing the door. Although this design simplifies the appearance of the door body, it brings many inconveniences in actual use. First, the lack of a clear handle design requires users to find a suitable point of force when opening and closing the door. Especially in an emergency, the user may be delayed because he cannot quickly find and grab the handle. Secondly, although the lock installed at one end can ensure the safety of the folding door after closing to a certain extent, its locking mechanism is often more complicated and requires manual operation by the user, which increases the cumbersomeness of use. Utility Model Content

[0003] In order to overcome at least one of the defects of the prior art, the utility model provides a multi-purpose handle for a folding door and a folding door mechanism, which can improve the practicality and convenience of a door lock.

[0004] The technical solution adopted by the utility model to solve the problem is:

[0005] A multi-purpose handle for a folding door is assembled between two door leaves, comprising: a handle main frame, the handle main frame comprising a hinged end and a clamping end, the hinged end is used to be hinged to the frame of one door leaf, and when the door leaves of the two folding doors are in a closed state, the clamping end is used to clamp to the frame of the other door leaf; a hand-holding portion, the hand-holding portion is arranged on a side of the handle main frame away from the door leaf, and a receiving groove for holding is formed between the hand-holding portion and the handle main frame.

[0006] By adopting the above solution, the setting of the hand-held part enables the user to easily find and hold the handle when opening or closing the folding door, and then complete the opening and closing of the door by simple rotation or push-pull action. This design reduces the inconvenience of users when opening and closing the door, and improves the convenience of operation; when the folding door is closed, the clamping end of the handle main frame is clamped with the frame of another door leaf. This design actually plays the role of a door lock, preventing the door leaf from being opened without permission. This door lock function simplifies the installation and use of traditional door locks, and also improves the safety of the folding door; and the handle is installed between the two door leaves. This design makes full use of the space between the door leaves and avoids the additional occupation of the wall or other space resources. This not only makes the folding door more compact and beautiful, but also improves the utilization rate of space.

[0007] Furthermore, the distance between the hand-held portion and the clamping end is smaller than the distance between the hand-held portion and the hinged end.

[0008] By adopting the above solution, since the handheld part is closer to the clamping end, when the user operates the handle, the force exerted by the hand will act more directly on the clamping end, which helps to strengthen the clamping effect between the clamping end and the frame of the other door leaf. This design can provide a stronger locking force when closing the folding door, thereby increasing the safety of the folding door.

[0009] Furthermore, the handheld part includes: a connecting section, which is integrally connected to the main handle frame, and the angle between the connecting section and the main handle frame is not greater than 90°; a pulling contact section, which is integrally connected to the connecting section, and the angle between the pulling contact section and the connecting section is not less than 90°.

[0010] By adopting the above solution, the angle between the connecting section and the main handle frame not being greater than 90° can reduce the overall space occupied by the main handle frame; and the angle between the pulling contact section and the connecting section not being less than 90° can provide a more definite pulling force line, improve the holding feeling, and the user can apply force to the folding door more directly through the pulling contact section, thus making it easier to open or close the door leaf.

[0011] Furthermore, a first flange is provided at one end of the pulling contact section away from the connecting section, and the first flange extends into the receiving groove.

[0012] By adopting the above solution, the setting of the first flange makes the end of the pulling contact section more prominent. When the user holds the handheld part, the fingers can naturally rest on the first flange, thereby increasing the stability and comfort of holding, and can also increase the contact area with the hand, increase the friction force, and prevent the fingers from accidentally slipping off.

[0013] Furthermore, a second flange is provided at the end of the clamping end, and the second flange extends in the direction of the hinge end.

[0014] By adopting the above solution, the setting of the second flange increases the contact area between the clamping end and the frame of the other door leaf, thereby enhancing the firmness and reliability of the clamping.

[0015] A folding door mechanism includes a folding door frame, a slide rail, at least two door leaves, an opening and closing member, and a multi-purpose folding door handle. An articulated seat is provided on one side of the door leaf close to the closing side of the folding door frame, the hinge end is hinged to the articulated seat, a clamping seat is provided on another door leaf corresponding to the door leaf with the articulated seat, and the clamping seat is correspondingly clamped with the clamping end.

[0016] By adopting the above solution, when the user needs to open the door, the clamping state between the clamping end and the clamping seat can be released by operating the multi-purpose handle of the folding door. Subsequently, the door leaf gradually unfolds along the opening and closing member under the guidance of the slide rail until it reaches the fully open state; conversely, when the user needs to close the door, the door leaf can be pushed back along the slide rail to the closed position. When approaching the closed state, the clamping end is clamped into the clamping seat to complete the locking, thus ensuring the safety after the door leaf is closed.

[0017] Further, the clamping seat includes: an arc surface, which is arranged facing the clamping end and is used to provide guidance for the clamping end; a clamping groove, which is used to be clamped with the clamping end, and the clamping groove is located on the side of the arc surface away from the clamping end.

[0018] By adopting the above solution, when the door leaf gradually approaches during the closing process, the clamping end will first contact the arc surface, enabling the clamping end to gradually approach the clamping groove along a smooth trajectory, thus avoiding direct impact, not only improving the smoothness of the clamping process, but also reducing the noise and wear during operation.

[0019] Further, the hinge seat and the hinge end are hinged by a hinge shaft.

[0020] By adopting the above solution, through the close cooperation of the hinge shaft and the hinge seat, the hinge end can rotate around the hinge shaft to facilitate the rotation of the handle.

[0021] Further, it further includes an unlocking mechanism, which is assembled in the door leaf. The unlocking mechanism includes a driving end and a triggering end. The triggering end faces the side of the door leaf away from the main frame of the handle, and the driving end faces the side of the door leaf where the main frame of the handle is assembled. Operation holes are reserved on the door leaf for the driving end and the triggering end respectively.

[0022] By adopting the above solution, the addition of the unlocking mechanism enables the handle to be operated even on the outer side of the door leaf, playing an emergency role.

[0023] Further, the unlocking mechanism further includes a reset member, which is used to reset the unlocking mechanism after it is driven and displaced from the driving end.

[0024] By adopting the above solution, when the unlocking mechanism is driven by the driving end to generate displacement to unlock the door leaf, the reset member will deform accordingly. After the unlocking action is completed, the reset member will automatically push the unlocking mechanism back to the initial position by using its elasticity and restoring force to prepare for the next operation.

[0025] To sum up, a multi-purpose handle for a folding door and a folding door mechanism provided by the present utility model have the following technical effects:

[0026] 1. The setting of the handheld part enables users to quickly find and hold the handle when they need to open or close the folding door. The door can be opened and closed through simple rotation or pushing / pulling actions, greatly reducing the inconvenience in operation. The handle is assembled between the two door leaves, making full use of the space and avoiding additional occupation of wall surfaces or other space resources, thus making the operation smoother.

[0027] 2. When the folding door is in the closed state, the clamping end of the handle main frame is clamped with the frame of the other door leaf. This design actually functions as a door lock, effectively preventing the door leaf from being opened without permission and improving the security of the folding door. Compared with traditional single-end installed locks, this design simplifies the locking mechanism, reduces the tediousness of manual operation by users, and also ensures the stability of the door leaf after closing.

Detailed Embodiment

[0036] 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 of the examples. All other examples obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the protection scope of the present invention.

[0037] For the convenience of understanding the embodiments of the present invention, the following will further explain with specific examples in conjunction with the drawings, and each embodiment does not constitute a limitation to the embodiments of the present invention.

[0038] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0040] Refer to Embodiment 1 of the present invention Figures 1-3As shown, a multi-purpose handle for a folding door is disclosed, which is assembled between two door leaves 5 and includes a main handle frame 1 and a hand-held part 2. The main handle frame 1 includes a hinged end 11 and a clamping end 12. The hinged end 11 is used to be hinged to the frame of one door leaf 5. When the two door leaves 5 of the folding door are in a closed state, the clamping end 12 is used to be clamped to the frame of the other door leaf 5. The hand-held part 2 is arranged on the side of the main handle frame 1 away from the door leaf. A receiving groove 21 for gripping is formed between the hand-held part 2 and the main handle frame 1. The arrangement of the hand-held part 2 enables users to easily find and hold the handle when they need to open or close the folding door, and then complete the opening and closing of the door through simple rotation or pushing and pulling actions. This design reduces the inconvenience of users when opening and closing the door and improves the operation convenience. In the closed state of the folding door, the clamping end 12 of the main handle frame 1 is clamped to the frame of the other door leaf 5. This design actually functions as a door lock, preventing the door leaf from being opened without permission. This door lock function simplifies the installation and use of traditional door locks and also improves the security of the folding door. Moreover, the handle is assembled between the two door leaves 5. This design makes full use of the space between the door leaves 5 and avoids occupying additional wall surface or other space resources. This not only makes the folding door more compact and beautiful but also improves the space utilization rate.

[0041] Preferably, referring to Figure 2 As shown, the main handle frame 1 and the hand-held part 2 are integrally formed. The hinged end 11 and the clamping end 12 at both ends of the main handle frame 1 are bent towards the door leaf 5 to form a U-shaped buckle-like structure, and the distance between the hand-held part 2 and the clamping end 12 is less than the distance between the hand-held part 2 and the hinged end 11. Since the hand-held part 2 is closer to the clamping end 12, when the user operates the handle, the force applied by the hand will act more directly on the clamping end 12, which helps to strengthen the clamping effect between the clamping end 12 and the frame of the other door leaf 5. This design can provide a stronger locking force when closing the folding door, thereby increasing the security of the folding door.

[0042] In a specific embodiment, referring to Figure 2As shown, the handheld part 2 includes a connecting section 22 and a pulling and touching section 23 for contacting the user's finger. The connecting section 22 is used to connect the main handle frame 1 and the pulling and touching section 23, and the connecting section 22, the pulling and touching section 23 and the main handle frame 1 are integrally connected. Optionally, the included angle between the connecting section 22 and the main handle frame 1 is not greater than 90°, and the included angle between the pulling and touching section 23 and the connecting section 22 is not less than 90°. In Embodiment 1, the included angle between the connecting section 22 and the main handle frame 1 is an acute angle, and the included angle between the pulling and touching section 23 and the connecting section 22 is an obtuse angle. With this setting, the overall space occupied by the main handle frame 1 can be reduced, and a more definite pulling force line can be provided, improving the holding feeling. The user can apply force to the folding door more directly through the pulling and touching section 23, so as to more easily open or close the door leaf.

[0043] To avoid the problem of slippage between the pulling and touching section 23 and the finger, in some embodiments, refer to Figure 2 As shown, a first flange 231 is provided at the end of the pulling and touching section 23 away from the connecting section 22. The first flange 231 extends into the receiving groove 21. The setting of the first flange 231 makes the end of the pulling and touching section 23 more prominent. When the user holds the handheld part 2, the finger can naturally rest on the first flange 231, thereby increasing the holding stability and comfort, and also increasing the contact area with the hand, increasing the friction force, and preventing the finger from slipping accidentally.

[0044] To improve the smoothness and stability of the clamping of the clamping end 12, in some embodiments, refer to Figure 2 As shown, a second flange 121 is provided at the end of the clamping end 12. The second flange 121 extends in the direction of the hinged end 11. The setting of the second flange 121 increases the contact area between the clamping end 12 and the frame of the other door leaf 5, thereby enhancing the firmness and reliability of the clamping. Preferably, a smooth arc transition is formed between the second flange 121 and the hinged end 11.

[0045] The present utility model also relates to a folding door mechanism. Refer to Figures 3-7As shown in the figure, it includes a folding door frame 3, a slide rail 4, at least two door panels 5, an opening and closing member 6, and a multi-purpose handle for a folding door. On one side of the door panel 5 near the closing side of the folding door frame 3, a hinge seat 52 is provided, and the hinge end 11 is hinged to the hinge seat 52. On another door panel 5 corresponding to the door panel 5 with the hinge seat 52, a clamping seat 51 is provided, and the clamping seat 51 is correspondingly clamped with the clamping end 12. When the user needs to open the door, the clamping state between the clamping end 12 and the clamping seat 51 can be released by operating the multi-purpose handle of the folding door. Subsequently, the door panel 5 gradually unfolds along the opening and closing member 6 under the guidance of the slide rail 4 until it reaches the fully open state; conversely, when the user needs to close the door, the door panel 5 can be pushed back along the slide rail 4 to the closed position. When approaching the closed state, the clamping end 12 is clamped into the clamping seat 51 to complete the locking, thereby ensuring the safety after the door panel 5 is closed.

[0046] Specifically, in this Embodiment 1, there are two door panels 5. The edges of the two door panels 5 are assembled with door frames, and the door frames are assembled with hanging pulleys. A slide rail 4 is provided inside the folding door frame 3, and the hanging pulleys slide inside the slide rail 4 so that the two folding doors can be folded and opened with each other. The clamping seat 51 includes an arc surface 511 and a clamping groove 512. The arc surface 511 faces the clamping end 12 and is used to provide guidance for the clamping end 12; the clamping groove 512 is located at the end of the arc surface 511 away from the clamping end 12 and is used to clamp with the clamping end 12. With this setting, when the door panels 5 gradually approach during the closing process, the clamping end 12 will first contact the arc surface 511, enabling the clamping end 12 to gradually approach the clamping groove 512 along a smooth trajectory, thus avoiding direct impact, not only improving the smoothness of the clamping process but also reducing the noise and wear during operation. Optionally, the connection between the clamping seat 51 and the door frame of the door panel 5 includes but is not limited to clamping, screwing, or integral connection.

[0047] In this Embodiment 1, the hinge end 11 is provided with a shaft hole, and the hinge seat 52 has a groove for accommodating the hinge end 11. Correspondingly, a hole for assembling a hinge shaft 521 is also provided in the groove corresponding to the shaft hole, so that the hinge seat 52 and the hinge end 11 are hinged by the hinge shaft 521. With this setting, the hinge end 11 can rotate around the hinge shaft 521, facilitating the rotation of the handle.

[0048] Under normal circumstances, the multi-purpose handle of the folding door is installed on the inner side of the folding door and is used as a lock when the door is closed to prevent the folding door from being opened from the outside of the door. In order to be able to open the lock from the outside in case of an emergency, an unlocking mechanism 7 is provided inside the folding door. The unlocking mechanism 7 is assembled in the door leaf 5. The unlocking mechanism 7 includes a driving end 71 and a triggering end 72. The triggering end 72 faces the side of the door leaf 5 away from the main handle frame 1, and the driving end 71 faces the side of the door leaf 5 where the main handle frame 1 is assembled. Operation holes 9 are reserved on the door leaf 5 for the driving end 71 and the triggering end 72 respectively. The addition of the unlocking mechanism 7 enables the handle to be operated even on the outside of the door leaf 5, playing an emergency role. Since the unlocking mechanism 7 is only for emergency use, a cover body can be provided on the outside of the door leaf 5 to block it, preventing ordinary people from discovering and opening the door.

[0049] In a specific embodiment, referring to Figure 3 As shown, the unlocking mechanism 7 is a rod-shaped structure. One end of the rod-shaped structure is the driving end 71, and the other end is the triggering end 72. In order to facilitate driving, the cross-sectional area of the triggering end 72 is made larger than that of the driving end 71, which can better receive force. When the triggering end 72 is pushed from outside the door, the driving end 71 will provide a thrust to the main handle frame 1, so that the clamping end 12 gradually disengages from the card slot 512, completing the unlocking. At this time, the outside of the door leaf 5 can be pushed and pulled at will to open or close the door.

[0050] In order to prevent the unlocking mechanism 7 from interfering with the clamping of the main handle frame 1 after being triggered, a resetting member 8 is also provided on the unlocking mechanism 7. The resetting member 8 is preferably a spring and is used to reset the unlocking mechanism 7 after being displaced by the driving end 71. With this setting, when the unlocking mechanism 7 is driven by the driving end 71 to generate displacement to unlock the door leaf 5, the resetting member 8 will deform accordingly. After the unlocking action is completed, the resetting member 8 will automatically push the unlocking mechanism 7 back to the initial position by using its elasticity and restoring force to prepare for the next operation.

[0051] In summary, a multi-purpose handle for a folding door and a folding door mechanism provided by the present utility model have the following technical effects:

[0052] 1. The setting of the hand-held part 2 enables users to quickly find and hold the handle when they need to open or close the folding door, and can complete the opening and closing of the door through simple rotation or pushing and pulling actions, greatly reducing the inconvenience in operation. The handle is assembled between the two door leaves 5, making full use of the space and avoiding occupying additional wall surfaces or other space resources, making the operation smoother;

[0053] 2. When the folding door is in the closed state, the clamping end 12 of the handle main frame 1 is clamped with the frame of another door leaf 5. This design actually functions as a door lock, effectively preventing the door leaf from being opened without permission and enhancing the security of the folding door. Compared with traditional single-end installed locks, this design simplifies the locking mechanism, reduces the cumbersome manual operation of users, and also ensures the stability of the door leaf after closing.

[0054] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
