Abstract
Description
Technical Field
[0001] This invention relates to the field of umbrella technology, specifically to a mechanically braked reverse umbrella with safety protection function and its braking method. Background Technology
[0002] Umbrellas are everyday household items that people use frequently. Using an umbrella on a rainy day can effectively prevent people from getting wet. The UV-protective coating on the umbrella surface can also prevent sunburn under sunlight, bringing great convenience to people's travel. However, when an umbrella is wet from rain, the wet outer surface faces outwards. When storing it, the wet outer surface will directly contact the storage bag, which is very inconvenient. Therefore, people have designed reverse umbrellas, which can cover the wet outer surface with the dry inner surface, thus avoiding direct contact between the storage bag and the wet outer surface, making it easier to store after use.
[0003] Although the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: during the automatic retraction process of the reverse umbrella, if the force is insufficient, it may not be able to retract and lock completely in one go. This can easily cause the elastic component inside the umbrella to release the elastic force generated by the compression rapidly outward, generating a strong kinetic energy impact, which can easily cause the user to suffer impact injury. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings and deficiencies of the prior art by providing a mechanically braked reverse umbrella that is safe to use, leaves minimal water droplet residue, and has a safety protection function.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mechanically braked reverse umbrella with safety protection function, comprising a center rod, a retrieval handle disposed at the bottom of the center rod, and umbrella ribs movably engaged at the top of the center rod. The upper surface of the umbrella ribs is covered with umbrella fabric. The retrieval handle includes a shell, a retrieval gear frame disposed within the shell, and a cable connected to the bottom of the center rod and wound around the outer wall of one side of the retrieval gear frame. A mechanical braking device is also fixedly disposed on one side of the retrieval gear frame. The top of the mechanical braking device is movably engaged with the inner wall of the shell. A switch movably connected to the other side of the retrieval gear frame is also disposed on the shell. The umbrella ribs include a connecting handle movably engaged at one end with the top of the center rod and a movable handle disposed at the other end of the connecting handle. A shaking ring for generating vibration is provided at the connection between the connecting handle and the movable handle. The shaking ring includes an outer ring connected to the connecting handle and an inner core connected to the movable handle. A support frame is provided between the outer wall of the inner core and the inner wall of the outer ring. A hammer frame is also provided on the outer wall of the inner core, and a shaking block is provided on the inner wall of the outer ring.
[0006] A further improvement is made to the mechanical braking device, which includes a central shaft fixedly connected to one side of the recovery gear frame and a rotating wheel fixedly disposed on the outer wall of the central shaft. The outer wall of the rotating wheel is provided with a locking tooth, the upper part of which contacts the bottom surface of the locking handle. The top of the locking handle is provided with a torsion spring ring, and the top of the locking handle is movably engaged with the inner wall of the outer casing through the torsion spring ring.
[0007] A further improvement is that the locking teeth are provided in a plurality of form, and the gaps between the plurality of locking teeth are evenly distributed on the outer wall of the rotating wheel.
[0008] A further improvement is that the locking teeth are hook-shaped protrusions, and the top surface of the locking teeth is rounded.
[0009] A further improvement is that the top of the hammer frame is provided with a solid, smooth iron ball.
[0010] A further improvement is that the hammering frame is provided in several parts, and the gaps between the hammering frames are evenly distributed on the outer wall of the inner core.
[0011] A further improvement is that the top surface of the shaking block is provided with several evenly distributed square sheets made of plastic material.
[0012] Based on the same concept, the present invention also provides a mechanical braking reverse umbrella braking method with safety protection function, comprising the following steps:
[0013] Step 1: Push the retraction handle upwards, which will rotate the retraction gear frame and drive the pull lock to retract, causing the middle rod to retract;
[0014] Step 2: Stop pushing the retractable handle upwards. The locking handle is engaged in the gap between the locking teeth by the torque of the torsion spring ring, preventing the retractable gear frame from driving the rotating wheel to rotate.
[0015] After adopting the above technical solution, the beneficial effects of the present invention are as follows: The present invention uses a mechanical braking structure to stop the umbrella during the recovery process, and can then perform multiple squeezes to recover it. Even if the umbrella is interrupted halfway through the recovery process, the bottom of the umbrella will not pop out quickly, thus avoiding danger during use. At the same time, the shaking ring will generate vibration during the opening and closing of the umbrella, shaking off the water droplets on the umbrella fabric, so that less water droplets remain after the umbrella is closed.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0023] See Figure 1-5 As shown, the technical solution adopted in this specific embodiment is as follows: Figure 1 As shown, a mechanically braked reverse umbrella with safety protection function is characterized by: including a center rod 1, a retractable handle 2 disposed at the bottom end of the center rod 1, and umbrella ribs 3 movably engaged at the top end of the center rod 1. The upper surface of the umbrella ribs 3 is covered with umbrella fabric 4. The umbrella fabric 4 is supported by the umbrella ribs 3 and the umbrella ribs 3 are supported by the center rod 1. At the same time, the umbrella ribs 3 are opened and folded by the retractable handle 2.
[0024] like Figure 2 As shown, the retrieval handle includes a housing, a retrieval gear frame disposed within the housing, and a cable connected to the bottom of the central rod and wound around the outer wall of one side of the retrieval gear frame. A mechanical braking device is also fixedly disposed on one side of the retrieval gear frame. The top of the mechanical braking device is movably engaged with the inner wall of the housing. A switch is also disposed on the housing and movably connected to the other side of the retrieval gear frame. The retrieval gear frame 22 can be twisted during retrieval, thereby simultaneously driving the pull lock 23 to be retracted and causing the mechanical braking device 24 to be twisted. When reverse rotation occurs, the mechanical braking device 24 brakes, thereby preventing reverse rotation and preventing the central rod 1 from popping out.
[0025] like Figure 3As shown, the mechanical braking device 24 includes a central shaft 31 fixedly connected to one side of the recovery gear frame 22 and a rotating wheel 32 fixedly disposed on the outer wall of the central shaft 31. The outer wall of the rotating wheel 32 is provided with a locking tooth 33. The upper part of the locking tooth 33 contacts the bottom surface of the locking handle 34. The top of the locking handle 34 is provided with a torsion spring ring 35. The top of the locking handle 34 is movably engaged with the inner wall of the outer casing 21 through the torsion spring ring 35. When rotating clockwise, the locking tooth 33 pushes open the locking handle 34 and maintains continuous downward pressure through the torsion spring ring 35, thereby allowing the rotating wheel 32 to rotate smoothly. When rotating counterclockwise, the bottom of the locking handle 34 is pressed down by the torsion spring ring 35 and will be engaged in the gap of the locking tooth 33 and abut against the locking tooth 33, so that the rotating wheel 32 cannot continue to rotate counterclockwise, thus achieving the braking effect.
[0026] The locking teeth 33 are provided in a plurality of manners, and in this embodiment there are eighteen manners. The gaps between the plurality of locking teeth 33 are evenly distributed on the outer wall of the rotating wheel 32, which helps to make the braking gap distance shorter, thereby obtaining better braking speed and braking effect.
[0027] The locking tooth 33 is a hook-shaped protrusion structure, and the top surface of the locking tooth 33 is rounded, which helps to reduce the resistance generated by clockwise rotation while ensuring the braking effect.
[0028] like Figure 4 As shown, the umbrella rib 3 includes a connecting handle 42 that is movably engaged with the top of the central rod 1 at one end, and a movable handle 41 located at the other end of the connecting handle 42. A shaking ring 43 for generating vibration is provided at the connection between the connecting handle 42 and the movable handle 41. When the umbrella rib 3 is opened and closed, the movable handle 41 and the connecting handle 42 twist each other, thereby causing the shaking ring 43 to generate a shaking effect, shaking off the water droplets on the umbrella fabric 4.
[0029] like Figure 5 As shown, the vibrating ring 43 includes an outer ring 51 connected to the connecting handle 42 and an inner core 54 connected to the movable handle 41. A support frame 53 is provided between the outer wall of the inner core 54 and the inner wall of the outer ring 51. A hammer frame 55 is also provided on the outer wall of the inner core 54. A vibrating block 52 is provided on the inner wall of the outer ring 51. When the movable handle 41 and the connecting handle 42 twist relative to each other, the inner core 54 and the outer ring 51 twist relative to each other. Then, the hammer frame 55 on the inner core 54 hammers the vibrating block 52, thereby producing an impact vibration effect.
[0030] The top of the hammer frame 55 is equipped with a solid, smooth iron ball, which helps to increase the impact force and thus obtain a stronger shaking intensity.
[0031] The hammering frame 55 is provided in several parts, and in this embodiment there are three parts. The gaps between the hammering frames 55 are evenly distributed on the outer wall of the inner core 54, which is conducive to generating more frequent impacts and thus making the vibration frequency higher.
[0032] The top surface of the shaking block 54 is provided with several evenly distributed square thin sheets made of plastic material. In this embodiment, five sheets are provided, which is beneficial to generate more impacts when in contact, thereby obtaining more high-frequency shaking and enhancing the water removal capacity.
[0033] Working principle of the invention: In use, the umbrella ribs 3 support the umbrella fabric 4, and the central rod 1 supports the umbrella ribs 3. The umbrella ribs 3 are opened and folded using the retraction handle 2. During retraction, the retraction gear frame 22 can twist, which simultaneously retracts the zipper 23 and activates the mechanical brake device 24. During normal retraction, the rotating wheel 32 is driven to rotate clockwise by the retraction gear frame 22. The locking teeth 33 push open the locking handle 34, and the torsion spring ring 35 maintains continuous downward pressure, allowing the rotating wheel 32 to rotate smoothly. When the retraction is halfway complete and released, the rotating wheel 32 is driven to rotate counterclockwise by the reverse-rotating retraction gear frame 22. The locking handle 34, pressed down by the torsion spring ring 35, engages with the gap in the locking teeth 33 and abuts against them, preventing the rotating wheel 32 from continuing to rotate counterclockwise. The rotation achieves a braking effect, thereby preventing reverse rotation and preventing the middle rod 1 from popping out. At the same time, when the umbrella ribs 3 open and close, the movable handle 41 and the connecting handle 42 twist each other. When the movable handle 41 and the connecting handle 42 twist each other, the inner core 54 and the outer ring 51 twist relative to each other. As a result, the hammer frame 55 on the inner core 54 hammers the shaking block 52, thereby generating an impact shaking effect. The shaking effect shakes off and removes water droplets on the umbrella fabric 4, thereby preventing water droplet residue. The present invention uses a mechanical braking device 24 to stop the umbrella during the recovery process, and can perform multiple squeezes to recover it. Even if the umbrella is interrupted halfway through closing, it will not cause the bottom of the umbrella to pop out quickly, avoiding danger during use. At the same time, the shaking ring will generate shaking during the opening and closing of the umbrella, shaking off water droplets on the umbrella fabric 4, so that less water droplets remain after closing the umbrella.
