Description

Technical Field

[0001] This invention belongs to the field of hanging safety technology for curtains or advertising curtains, and specifically relates to a fall prevention system for hanging curtain rods. Background Technology

[0002] Advertising curtains and giant curtains are typically installed using a hanging method, where a horizontally placed hanging rod serves as the top, suspending the curtains and curtains. However, if these curtains or curtains fall, they can easily injure pedestrians, creating a safety hazard. Therefore, it is necessary to equip the hanging rod with a corresponding fall protection system. Existing fall protection systems generally use motors or electromagnets to prevent falls, but these two methods rely on electricity and are mostly used in hoisting or elevator applications, such as patents CN119079750A ("A Traction-Type Fall Protection Elevator for Small Spaces and Its Fall Protection Method") and CN119079763A ("A Fall Protection Electromagnet Hoisting Steel Bar Device and Fall Protection Method"). Currently, there is a market gap for fall protection systems for curtains or advertising curtains. Therefore, it is necessary to design a fall protection system suitable for hanging curtains or advertising curtains. Summary of the Invention

[0003] To address the aforementioned problems in existing technologies, this solution provides a fall prevention system for suspended curtain rods.

[0004] The technical solution adopted in this invention is as follows:

[0005] A fall protection system for a suspended curtain rod includes a fall protection bracket and a fall protection locking device;

[0006] The anti-fall bracket includes a groove-shaped component and anti-fall teeth; the groove-shaped component is vertically installed on the side wall during use, and several anti-fall teeth are installed alternately in the groove cavity of the groove-shaped component;

[0007] The anti-fall locking device includes an outer shell, a telescopic locking head, a compression spring, and a linkage locking component. The outer shell is fixedly installed at the end of the hanging curtain rod. The telescopic locking head is horizontally movable within the outer shell, and its head can extend out of or retract into the outer shell. The compression spring abuts against the tail of the telescopic locking head, and the spring force of the compression spring is used to push the telescopic locking head out of the outer shell. The linkage locking component is rotatably installed within the outer shell and includes a rotating arm, a locking hook, and a connecting part. The rotating arm has a rotating shaft in the middle and is rotatably connected to the outer shell. The two ends of the rotating arm are the locking hook and the connecting part, respectively. The locking hook is used to lock the telescopic locking head, so that the telescopic locking head is in the retracted state of the outer shell. The connecting part is used to connect the suspension rope to suspend the hanging curtain rod.

[0008] When the suspension rope breaks, the linkage lock unlocks the telescopic latch, and the head of the telescopic latch extends out of the outer shell and abuts against the anti-falling teeth to prevent the suspension curtain rod from falling.

[0009] As an alternative or supplement to the above solution: the groove wall on both sides of the groove-shaped component is provided with an insert groove, and the anti-falling tooth is provided with an insert tenon at both ends of the anti-falling tooth. The insert tenon can be inserted into the insert groove to install the anti-falling tooth.

[0010] As an alternative or supplement to the above solution: the anti-fall teeth are trapezoidal or right-angled triangles.

[0011] As an alternative or supplement to the above solution: the side of the outer shell is provided with a first opening, the head of the telescopic clip is triangular or trapezoidal and faces the first opening, and the head of the telescopic clip can extend out of the outer shell from the first opening.

[0012] As an alternative or supplement to the above solution: the top of the outer shell is provided with a second opening, and the upper end of the hanging part extends out of the outer shell from the second opening and is connected to the suspension rope.

[0013] As an alternative or supplement to the above solution: a third opening is provided on the top of the outer shell, and a handle is fixedly connected above the locking hook. The upper end of the handle extends out of the outer shell from the third opening to facilitate manual unlocking of the telescopic locking head.

[0014] As an alternative or supplement to the above solution: a counterweight is fixed below the hanging part. The counterweight is used to lift the locking hook part when the suspension rope is disconnected, so as to unlock the telescopic locking head.

[0015] As an alternative or supplement to the above solution: a guide tenon is provided on the side wall of the telescopic head, and a guide groove that mates with the guide tenon is provided on the inner wall of the outer shell; a limiting protrusion is provided on the side wall of the telescopic head, and the limiting protrusion can abut against the second opening to prevent the telescopic head from falling out of the outer shell.

[0016] As an alternative or supplement to the above solution: a spring base is provided inside the outer shell, and a notch is provided on the side of the spring base facing the telescopic clip head, and the end of the compression spring extends into the notch and abuts against the spring base.

[0017] The beneficial effects of this invention are as follows: the fall protection system in this solution adopts a purely mechanical structure, requires no power supply, and has higher safety and reliability in fall protection; moreover, compared with the existing technology that uses power-consuming equipment such as motors and electromagnets to achieve fall protection, this solution does not require continuous power consumption, has lower cost, simple structure, and good installation convenience.

Detailed Implementation

[0026] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0027] like Figures 1 to 6 As shown, this embodiment designs a fall prevention system for a suspended curtain rod, including a fall prevention bracket 2 and a fall prevention locking device 4.

[0028] The fall arrestor 2 includes components such as a grooved part 21 and fall arrestor teeth 22. The grooved part 21 can be made of spliced ​​plates or a pre-formed grooved part. When in use, the grooved part 21 is vertically fixed to the side wall 1, with the groove opening of the grooved part 21 facing the hanging curtain rod 3. Several fall arrestor teeth 22 are installed alternately in the groove cavity of the grooved part 21. A gap is formed between adjacent fall arrestor teeth 22 to facilitate the locking of the fall arrestor device 4.

[0029] like Figure 2 As shown, the grooved component 21 and the anti-falling tooth 22 can be connected in a detachable manner. Specifically, the grooved component 21 has mounting grooves 211 on its opposite sides, and the anti-falling tooth 22 has mounting tenons 221 at its opposite ends. The mounting tenons 221 can be inserted into the mounting grooves 211 to install the anti-falling tooth 22. The anti-falling tooth 22 is generally trapezoidal or right-angled triangular, but other shapes are also possible.

[0030] The anti-fall locking device 4 includes components such as an outer shell 41, a telescopic locking head 42, a compression spring 45, and a linkage locking component 44.

[0031] The outer casing 41 can be a rectangular box or a circular box, or other shapes. When in use, the outer casing 41 is fixedly installed to the end of the hanging curtain rod 3. A fall arresting device 4 is installed at each end of the hanging curtain rod 3, thereby achieving the locking and fall prevention at both ends of the hanging curtain rod 3.

[0032] The telescopic locking head 42 is horizontally movable within the outer casing 41. The telescopic locking head 42 can reciprocate between a retracted position and an extended position for repeated use. When the telescopic locking head 42 is in the extended position, its head extends outside the outer casing 41, at which point the fall protection system is activated (i.e., the fall protection locking device 4 is locked onto the fall protection seat 2). Figure 6 As shown; when the telescopic locking head 42 is in the retracted position, the telescopic locking head 42 retracts into the outer shell 41, at which time the fall protection system is in a non-triggered state, as shown. Figure 5 As shown.

[0033] The telescopic head 42 is provided with a guide tenon 421 on its side wall, and a guide groove that mates with the guide tenon 421 is provided on the inner wall of the outer shell 41; a limiting protrusion 422 is provided on the side wall of the telescopic head 42, and the limiting protrusion 422 can abut against the second opening 412 to prevent the telescopic head 42 from falling out of the outer shell 41.

[0034] The outer shell 41 has a first opening 411 on its side. The head of the telescopic locking head 42 can be triangular or trapezoidal and is directly opposite the first opening 411. The head of the telescopic locking head 42 can extend out of the outer shell 41 from the first opening 411 and extend between the adjacent anti-fall locking teeth 22, thereby realizing the locking of the anti-fall locking device 4.

[0035] The compression spring 45 abuts against the tail of the telescopic latch 42, and the elastic force of the compression spring 45 is used to push the telescopic latch 42 out of the outer shell 41. A spring base is provided inside the outer shell 41, and a notch is provided on the side of the spring base facing the telescopic latch 42. The end of the compression spring 45 extends into the notch and abuts against the spring base. When the telescopic latch 42 is in the retracted position, the compression spring 45 is in a compressed state. When the telescopic latch 42 is not locked by the linkage lock 44, the elastic force of the compression spring 45 can push the telescopic latch 42 to the extended position.

[0036] The linkage locking component 44 is rotatably disposed within the outer casing 41. The linkage locking component 44 includes a rotating arm 443, a locking hook 442, and a connecting part 441. The rotating arm 443 is long-arm shaped, with a rotating shaft in the middle and rotatably connected to the outer casing 41. The two ends of the rotating arm 443 are the locking hook 442 and the connecting part 441, respectively. The locking hook 442 is used to lock the telescopic latch 42, so that the telescopic latch 42 is in the retracted state of the outer casing 41. The connecting part 441 is used to connect the suspension rope 5 to suspend the suspension curtain rod 3. The linkage locking component 44 can form a lever structure. When the connecting part 441 moves downward, the locking hook 442 tilts upward. When the connecting part 441 is pulled upward by the suspension rope 5, the locking hook 442 hooks downward to lock the telescopic latch 42. Specifically, it can hook the limiting protrusion 422 on the upper side of the telescopic latch 42.

[0037] The top of the outer shell 41 is provided with a second opening 412. The upper end of the hanging part 441 extends out of the outer shell 41 through the second opening 412 and is connected to the suspension rope 5. The top of the outer shell 41 is provided with a third opening 413. A handle part 444 is fixedly connected above the locking hook part 442. The upper end of the handle part 444 extends out of the outer shell 41 through the third opening 413 to facilitate manual unlocking of the telescopic locking head 42.

[0038] A counterweight 43 is fixed below the hanging part 441. The counterweight 43 is used to lift the locking hook part 442 when the suspension rope 5 is disconnected, so as to unlock the telescopic locking head 42. When the anti-fall locking device 4 falls, it is easily affected by factors such as the side wall 1 and wind resistance, so that it cannot fall slower than the counterweight 43, ensuring that the linkage lock 44 can be unlocked. In addition, a torsion spring can be set at the rotation shaft of the linkage lock 44, or an elastic rope can be set between the hanging part 441 and the lower side wall of the outer shell 41, so that when the hanging part 441 loses the tension of the suspension rope 5, the linkage lock 44 can rotate to unlock the telescopic locking head 42.

[0039] When the fall arrest system in this solution is in use: With the suspension rope 5 suspending the fall arrest device 4, the suspension rope 5 applies tension to the connecting part 441, causing the linkage lock 44 to lock the telescopic locking head 42, thus ensuring the smooth raising and lowering of the suspended curtain rod 3. When the suspension rope 5 disconnects, the linkage lock 44 unlocks the telescopic locking head 42, and the head of the telescopic locking head 42 extends out of the outer shell 41 and abuts against the fall arrest teeth 22 to prevent the suspended curtain rod 3 from falling, thereby achieving the fall arrest effect and ensuring the safety of pedestrians on the ground.

[0040] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
