A flip-up door panel for a loft ladder

Abstract

This utility model discloses a flip-up door panel for a loft telescopic ladder, relating to the technical field of telescopic ladders. The utility model includes a main body assembly and a fixing assembly. The main body assembly includes an outer frame, with a door panel hinged to a groove within the outer frame. A protruding plate is fixed to one side of the door panel, and a flip-up groove adapted to the protruding plate is also provided on the outer frame. The fixing assembly includes an electric push rod fixed to the upper surface of the door panel. A connecting plate is fixed to the telescopic end of the electric push rod, and a connecting rod is horizontally movably connected to the connecting plate. Through the fixing assembly, when in use, activating the electric push rod moves the connecting plate backward, which pulls a spring backward.

This solves the problem in existing solutions where door panels often lack a fixed latch and rely solely on the telescopic rod for support, leading to sagging over time.

Description

Technical Field

[0001] This utility model belongs to the technical field of telescopic ladders, and in particular relates to a flip-up door panel of an attic telescopic ladder. Background Technology

[0002] Attic retractable ladders are convenient access tools designed specifically for attics and other high-altitude spaces. They are typically made of lightweight and durable materials such as aluminum alloy and carbon steel. Their length can be adjusted by stretching or folding, and they can be retracted for storage when not in use, saving a lot of space. The flip-up door panel is an important component of this ladder. The door panel is cleverly connected to the ladder and can be used as a cover for the attic entrance when not in use, flush with the ceiling to keep the space neat and tidy. When the ladder is needed, simply flip the door panel upwards, and the retractable ladder hidden inside will unfold. No additional disassembly or installation is required, which is both convenient and quick. The load-bearing design of the door panel enhances safety, making it especially suitable for daily access and storage of items in attics in homes, warehouses, and other similar settings.

[0003] However, it still has the following drawbacks in actual use: Most of the existing retractable staircases have outward-folding doors that are supported by telescopic rods on the retractable staircases to keep them horizontally suspended. Over a long period of use, the doors are prone to naturally sagging, which can easily wear out the lifespan of the telescopic rods. Utility Model Content

[0004] The purpose of this utility model is to provide a flip-up door panel for a loft telescopic ladder. This utility model solves the problem that most existing door panels do not have fixed latches and are supported by the telescopic rod on the telescopic ladder, which can easily lead to the door panel sagging over time.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a flip-type door panel for a loft telescopic ladder, including a main component and a fixing component. The main component includes an outer frame, a door panel is hinged to the inner groove of the outer frame, a protruding plate is fixed on one side of the door panel, and a folding groove adapted to the protruding plate is also provided on the outer frame.

[0007] The fixing component includes an electric push rod fixed to the upper surface of the door panel. A connecting plate is fixed to the telescopic end of the electric push rod. A connecting rod is horizontally and movably connected to the connecting plate. A plug is fixed to one end of the connecting rod. A spring is also provided on the outer periphery of the connecting rod. The two ends of the spring are fixed to the opposite surfaces of the connecting plate and the plug, respectively.

[0008] The outer frame has a connector slot that matches the connector, and the door panel also has a through slot. The fixing component also includes a handle, which is located on the lower surface of the door panel and is fixedly connected to the connector through the through slot.

[0009] Furthermore, the main component also includes two sets of connectors, which are fixed to the upper surface of the door panel.

[0010] Furthermore, a limiting component is fixed to the upper surface of the door panel, with two of each of the connecting rod, spring, and limiting component.

[0013] Furthermore, a housing is provided on the outer periphery of the fixing component, and the housing is fixed to the upper surface of the door panel.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, through the setting of a fixed component, when in use, the electric push rod is activated to drive the connecting plate to move backward, the connecting plate will pull the spring to move backward, and finally the spring pulls the plug-in part to disengage from the plug-in slot, at which point the door panel can be opened, and vice versa, the door panel can be closed. This solves the problem in the existing solution that most door panels do not have fixed latches and are supported by the telescopic rod on the telescopic staircase, which easily leads to the door panel sagging over time.

[0016] 2. This utility model solves the problem in the above solutions where the door cannot be opened in time if the remote control is not found or the internal components malfunction. The fixed component is also equipped with a retractable staircase that can be opened manually. Simply pull the handle to move the plug-in part out of the plug-in slot.

[0017] 3. The main components of this utility model include a protruding plate on the door panel and a folding groove on the outer frame.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figure 1-5 As shown, this utility model is a flip-type door panel for a loft telescopic ladder, including a main component 1 and a fixing component 2. The main component 1 includes an outer frame 11, with a door panel 12 hinged to the inner groove of the outer frame 11. A protruding plate 13 is fixed to one side of the door panel 12. A folding groove 14 adapted to the protruding plate 13 is also provided on the outer frame 11. The main component 1 consists of the door panel 12 body and its outer fixing frame, used to fix and install the telescopic ladder. The fixing component 2 is used to lock the door panel 12 when not in use, so that the telescopic ladder is fixed above the loft and can only be removed when in use. The design of the protruding plate 13 and the folding groove 14 ensures that the hinge of the hinged door panel 12 is not exposed during installation, while also ensuring that the door panel 12 can flip normally, making it more beautiful and elegant.

[0028] The fixing component 2 includes an electric push rod 21 fixed to the upper surface of the door panel 12. A connecting plate 22 is fixed to the telescopic end of the electric push rod 21. A connecting rod 23 is horizontally and movably connected to the connecting plate 22. A connector 25 is fixed to one end of the connecting rod 23. A spring 24 is also provided on the outer periphery of the connecting rod 23. The two ends of the spring 24 are respectively fixed to the opposite surfaces of the connecting plate 22 and the connector 25. The electric push rod 21 is used to push the connector 25 and the connector slot 26 to interlock and lock the door panel 12, thereby realizing the opening and closing of the door panel 12. The connecting rod 23 and the spring 24 are also provided in the middle, so that while locking by the electric push rod 21, the connector 25 can also be manually pushed out of the connector slot 26, so that it can be opened by both numerical control and manual control, thus improving its functionality.

[0029] The outer frame 11 has a plug groove 26 that is compatible with the plug 25, and the door panel 12 also has a through groove 27. The fixing component 2 also includes a handle 28. The handle 28 is set on the lower surface of the door panel 12, and the handle 28 passes through the through groove 27 and is fixedly connected to the plug 25. The handle 28 is used to facilitate manual opening of the door panel 12.

[0030] Furthermore, the main component 1 also includes two sets of connectors 15, which are fixed to the upper surface of the door panel 12. The connectors 15 are used for the installation of the telescopic staircase.

[0031] Furthermore, a limiting member 29 is also fixed on the upper surface of the door panel 12. There are two of each of the connecting rod 23, spring 24 and limiting member 29. The limiting member 29 is used to restrict the movement of the connecting plate 22 and prevent the electric push rod 21 from extending or retracting excessively, which would prevent the door panel 12 from being opened manually.

[0032] Furthermore, the vertical viewing angle area of ​​the handle 28 is larger than that of the vertical viewing angle area of ​​the through groove 27, so that the handle 28 can completely cover the through groove 27, increasing the overall aesthetics.

The infrared sensor 212 can be directly remotely controlled to open or close the door panel 12, greatly increasing the convenience of use.

[0034] Furthermore, a housing 16 is provided on the outer periphery of the fixing component 2. The housing 16 is fixed to the upper surface of the door panel 12. The housing 16 is used to ensure the safety of the fixing component 2 and prevent damage to the internal components due to external factors.

[0035] The specific working principle of this utility model is as follows: When using this device, the outer frame 11 is fixed to the attic entrance where the retractable staircase is to be installed. Then, the retractable staircase is installed on the door panel 12 through the connector 15. The door panel 12 is also provided with a protruding plate 13, and the outer frame 11 is also provided with a folding groove 14. The design of the protruding plate 13 and the folding groove 14 ensures that the hinge of the hinged door panel 12 will not be exposed during installation, while ensuring that the door panel 12 can be flipped normally, making it more beautiful and elegant.

[0036] When the door panel 12 needs to be opened, the electric push rod 21 is activated by the remote control and its infrared sensor 212. The electric push rod 21 drives the connecting plate 22 to move backward. During this process, the connecting plate 22 pulls the spring 24 to move backward. Finally, the spring 24 pulls the connector 25 to disengage from the connector slot 26, at which point the door panel 12 can be opened and the telescopic staircase can be used. Conversely, the door panel 12 can be closed. At the same time, the device can also be opened manually by pulling the handle 28 to disengage the connector 25 from the connector slot 26. It can be used when the remote control is not found or the internal components are malfunctioning, which greatly improves its convenience.

[0037] The above are merely preferred embodiments of the present utility model and do not limit the present utility model.
