Description

Technical Field

[0001] This utility model relates to the field of multi-fold umbrellas, specifically a multi-fold umbrella center rod structure designed to prevent hand strikes. Background Technology

[0002] A multi-fold umbrella is an umbrella that can be folded to significantly reduce its storage volume. It uses a combination of multi-section umbrella ribs and a sliding umbrella cover to allow the umbrella to be opened for rain protection and closed for easy carrying and storage. It is widely used in daily travel, tourism and other scenarios, meeting people's needs for the portability and practicality of umbrellas.

[0003] In the use of umbrellas, the automatic closing function brings convenience to users. Existing three-pole automatic multi-fold umbrellas rely on the instantaneous automatic closing of the three poles to achieve rapid closing. However, when a person closes the umbrella with one hand, the umbrella slide will quickly approach the umbrella handle at the hand's position as the three poles close. This rapid movement process is prone to generating impact force, resulting in "hitting" the hand, affecting the user experience, and may even injure the hand due to the impact force.

[0004] To address the issue of automatic umbrella closing causing hand injury, a four-bar design has emerged in the market. This involves adding a set of bars above the umbrella handle. During automatic closing, only the first three bars closest to the umbrella frame retract instantly, while the fourth bar requires manual pushing to retract. While this design prevents the umbrella from hitting the hand during automatic closing, the increased number of bars and mounting components adds to the assembly process, thus increasing the production cost of the umbrella. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a multi-fold umbrella center rod structure that prevents hand strikes, in order to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-fold umbrella shaft structure for preventing hand strikes, comprising a first umbrella shaft, a second umbrella shaft connected to the bottom of the first umbrella shaft, a third umbrella shaft provided at the bottom of the second umbrella shaft, and the first umbrella shaft, the second umbrella shaft, and the third umbrella shaft combined to form an umbrella shaft assembly, an upper ferrule installed at the top of the first umbrella shaft, a fixed pulley provided inside the upper ferrule, a slider sleeved on the outer wall of the first umbrella shaft, a protrusion provided on the outer surface of the slider, a movable pulley installed inside the protrusion, a first rubber plug and a second rubber plug respectively installed at the top of the inner ends of the second umbrella shaft and the third umbrella shaft, a closing positioning member slidably passing through the second rubber plug, a guide wire connected to the top of the closing positioning member, and the guide wire sequentially winding around the fixed pulley and the movable pulley.

[0007] By adopting the above technical solution, the technical problem of hand injury during the automatic retrieval of a three-pole umbrella is solved. When a person presses the release device with one hand, the second spring, which is in a stretched state, drives the umbrella ribs and connecting rods to move closer together. This causes the slider to move the lead wire located outside the first umbrella pole downwards. As a result, the first steel wire connected to one end of the lead wire drives the third and second umbrella poles to retract into the first umbrella pole through the second rubber plug. This makes it easier for the person to close the umbrella with one hand, increasing the overall convenience of the umbrella. Furthermore, when the slider moves to the top of the release device, the first rubber plug obstructs the first steel wire, causing the second umbrella pole, which is retracted into the first umbrella pole, to be a certain distance from the top of the handle. This prevents the hand holding the release device from being squeezed by the handle during the umbrella retrieval process, thus improving the user's safety.

[0008] The present invention is further configured such that the closing and positioning component is a first steel wire, and the outer walls of the second rubber plug are provided with sliding grooves on both sides; the first steel wire slides through the sliding grooves.

[0009] The present invention is further configured such that the first steel wire is U-shaped and elastic, and two sets of anti-detachment coils are fixed at the bottom end of the first steel wire.

[0010] Preferably, during the process of closing the umbrella, the lead wire can drive the third umbrella rod, which is fixed with the second rubber plug, to close inward through the first steel wire.

[0011] The present invention is further configured such that a first spring and a second spring are respectively installed inside the first rubber stopper and the second rubber stopper, and a first spring is fixed to the end of each of the first spring and the second spring, and a hole is opened at the bottom of each of the first umbrella rod and the second umbrella rod.

[0012] Preferably, when the umbrella is fully deployed, the first and second umbrella poles are fixed by the snap fasteners of the first spring post, and the second and third umbrella poles are fixed by the snap fasteners of the second spring post, so that the umbrella pole assembly can remain fixed.

[0013] The present invention is further configured such that a connecting rod is connected to the outer wall of the slider, an umbrella rib rod is provided on the outer wall of the upper nest, a second spring is installed inside the umbrella rib rod, and the end of the second spring is connected to the connecting rod, and the second spring is always in a stretched state.

[0014] Preferably, when the umbrella rod assembly is in a fixed state, the stretched second spring pulls the umbrella rib rod and the connecting rod closer together, thereby allowing the slider to slide downward along the first umbrella rod.

[0015] The present invention is further configured such that a wire hole is provided at the top of the upper nest, and a knot is provided at the end of the lead wire, and the knot is fixedly provided at the top of the upper nest.

[0016] Preferably, one end of the lead wire wound on the movable pulley passes through the wire hole into the upper nest, and the wire hole at the top of the upper nest is fixed by limiting the knot, thereby fixing one end of the lead wire at the top of the upper nest.

[0017] The present invention is further configured such that the lead wire is wound around the fixed pulley and the movable pulley in sequence, and the lead wire connected to the bottom of the knot passes through the movable pulley and the fixed pulley in sequence and is connected to the top of the first steel wire.

[0018] Preferably, when the slider moves, based on the principle of lever saving, the slider will drive the first steel wire to move through the pull wire, and the distance the first steel wire moves is equal to twice the distance the slider moves.

[0019] The present invention is further configured such that a groove is formed on the outer wall of the first rubber stopper, and the groove vertically penetrates the first rubber stopper.

[0020] Preferably, the lead wire located inside the second umbrella shaft is connected to the inside of the third umbrella shaft through a groove inside the first rubber plug.

[0021] The present invention is further configured such that a handle is fixed to the bottom of the third umbrella pole, and a protective sleeve is provided on the outer wall of the handle.

[0022] Preferably, the handle has a rubber protective sleeve installed on its outer wall, which can increase the friction between the handle and the user's hand.

[0023] The present invention is further configured such that a release device is fixed at the bottom of the first umbrella pole, and a button is provided on the outer wall of the release device.

[0024] Preferably, when it is necessary to release the latch between the first spring and the first and second umbrella poles, simply press the button on one side of the contactor. The button will push the first spring into the first rubber plug.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model solves the technical problem of hand injury during automatic retrieval of a three-pole umbrella by setting up a first umbrella pole, a second umbrella pole, a third umbrella pole, a first rubber plug, a second rubber plug, a guide wire, and a first steel wire. When a person presses the release device with one hand, the second spring in a stretched state drives the umbrella ribs and connecting rods to move closer together, causing the slider to move the guide wire located outside the first umbrella pole downwards. This causes the first steel wire connected to one end of the guide wire to drive the third umbrella pole and the second umbrella pole to retract into the first umbrella pole through the second rubber plug, making it convenient for the person to close the umbrella with one hand and increasing the overall convenience of the umbrella. Furthermore, when the slider moves to the top of the release device, the first rubber plug obstructs the first steel wire, causing the second umbrella pole, which is retracted into the first umbrella pole, to be a certain distance from the top of the handle. This prevents the hand holding the release device from being squeezed by the handle during the umbrella retrieval process, thereby improving the user's safety.

[0027] 2. This utility model, by setting up a slider, a fixed pulley, a movable pulley, and an upper nest, allows the slider to move vertically upwards or downwards along the outer wall of the first umbrella pole. As the slider moves, the connecting wire connected to the top of the first steel wire sequentially winds around the fixed pulley inside the upper nest and the movable pulley inside the slider. When the slider moves one unit distance, the connecting wire, after being pulled by the pulley group composed of the fixed and movable pulleys, will move two unit distances inside the first umbrella pole. This allows the connecting wire to drive the third and second umbrella poles to retract into the first umbrella pole when the slider slides down from the top to the bottom of the first umbrella pole.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] The embodiments of this utility model will be described below based on its overall structure.

[0043] First embodiment:

[0044] Please see Figure 1 — Figure 10The system includes a first umbrella pole 1, a second umbrella pole 2 connected to the bottom of the first umbrella pole 1, and a third umbrella pole 3 located at the bottom of the second umbrella pole 2. The first umbrella pole 1, second umbrella pole 2, and third umbrella pole 3 are combined to form an umbrella pole assembly. An upper housing 4 is installed at the top of the first umbrella pole 1, and a fixed pulley 401 is installed inside the upper housing 4. A slider 5 is fitted onto the outer wall of the first umbrella pole 1, and a protrusion 501 is provided on the outer surface of the slider 5. A movable pulley 502 is installed inside the protrusion 501. A first rubber plug 202 and a second rubber plug 304 are respectively installed at the top of the inner ends of the second umbrella pole 2 and the third umbrella pole 3. A closing positioning component slides through the second rubber plug 304, and a guide line 6 is connected to the top of the closing positioning component. The guide line 6 sequentially winds around the fixed pulley 401 and the movable pulley 502. This solves the technical problem of the umbrella hitting the user during automatic retrieval in a three-pole structure. When a person presses the release device 8 with one hand, the second spring 404, which is in a stretched state, drives the umbrella ribs 403 and the connecting rod 405 to move closer together. This causes the slider 5 to move the lead wire 6 located outside the first umbrella pole 1 downwards. As a result, the closing positioning component connected to one end of the lead wire 6 drives the third umbrella pole 3 and the second umbrella pole 2 to retract into the first umbrella pole 1 through the second rubber plug 304. This makes it convenient for the person to close the umbrella with one hand, increasing the overall ease of use of the umbrella. Furthermore, when the slider 5 moves to the top of the release device 8, the first rubber plug 202 obstructs the closing positioning component, causing the second umbrella pole 2, which is retracted into the first umbrella pole 1, to be a certain distance from the top of the handle 301. This prevents the hand holding the release device 8 from being squeezed by the handle 301 during the umbrella retraction process, thereby improving the user's safety.

[0045] In the above embodiment, the closing and positioning component is a first steel wire 7, and the outer walls of the second rubber plug 304 are provided with sliding grooves 305; the first steel wire 7 slides through the sliding grooves 305. Please refer to the details for further information. Figure 5 The first steel wire 7 is U-shaped and elastic. Two sets of anti-detachment coils 701 are fixed at the bottom of the first steel wire 7. When the umbrella body is closed, the lead wire 6 can drive the third umbrella rod 3, which is fixed with the second rubber plug 304, to close into the first umbrella rod 1 through the first steel wire 7.

[0046] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 and Figure 8 The first rubber plug 202 and the second rubber plug 304 are respectively installed with a first spring 201 and a second spring 302. The ends of the first spring 201 and the second spring 302 are fixed with a first spring 303. The bottom of the first umbrella pole 1 and the second umbrella pole 2 are both provided with holes. When the umbrella is fully opened, the first umbrella pole 1 and the second umbrella pole 2 are fixed by the buckle of the first spring 201, and the second umbrella pole 2 and the third umbrella pole 3 are fixed by the buckle of the second spring 302, so that the umbrella pole assembly can be kept in a fixed state.

[0047] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The outer wall of the slider 5 is connected to a connecting rod 405, and the outer wall of the upper nest 4 is provided with an umbrella rib rod 403. A second spring 404 is installed inside the umbrella rib rod 403, and the end of the second spring 404 is connected to the connecting rod 405. The second spring 404 is always in a stretched state. When the umbrella rod assembly is in a fixed state, the stretched second spring 404 pulls the umbrella rib rod 403 and the connecting rod 405 closer together, so that the slider 5 can slide down along the first umbrella rod 1.

[0048] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 7 The top of the upper nest 4 is provided with a wire hole 402, and the end of the lead wire 6 is provided with a knot 601. The knot 601 is fixedly set on the top of the upper nest 4. One end of the lead wire 6, which is wound on the movable pulley 502, passes through the wire hole 402 and passes through the upper nest 4. The wire hole 402 at the top of the upper nest 4 is fixed by limiting the knot 601, so that one end of the lead wire 6 is fixedly set on the top of the upper nest 4.

[0049] For details regarding the above embodiments, please refer to [link / reference]. Figure 9 The pull wire 6 is wound around the fixed pulley 401 and the movable pulley 502 in sequence. The pull wire 6 connected to the bottom of the knot 601 passes through the movable pulley 502 and the fixed pulley 401 in sequence and is connected to the top of the first steel wire 7. When the slider 5 moves, based on the lever principle of saving effort, the slider 5 will drive the first steel wire 7 to move through the pull wire 6, and the distance that the first steel wire 7 moves is equal to twice the distance that the slider 5 moves.

[0050] For details regarding the above embodiments, please refer to [link / reference]. Figure 8 and Figure 9 The outer wall of the first rubber stopper 202 is provided with a wire groove 203, and the wire groove 203 vertically penetrates the first rubber stopper 202. The lead wire 6 located inside the second umbrella rod 2 is connected to the third umbrella rod 3 through the wire groove 203 inside the first rubber stopper 202.

[0051] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The bottom of the third umbrella pole 3 is fixed with an umbrella handle 301, and the outer wall of the umbrella handle 301 is covered with a protective sleeve. The handle 301 with a rubber protective sleeve installed on the outer wall can increase the friction between the handle 301 and the person's hand.

[0052] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 9A release device 8 is fixed at the bottom of the first umbrella pole 1. A button 801 is provided on the outer wall of the release device 8. When it is necessary to release the first spring 201 from the buckle between the first umbrella pole 1 and the second umbrella pole 2, it is only necessary to press the button 801 on one side of the contactor 8. The button 801 will squeeze and push the first spring 201 into the first rubber plug 202.

[0053] Second embodiment:

[0054] In this embodiment, the retractable positioning component is a second steel wire 702, and a groove 305 is formed on one side of the outer wall of the second rubber plug 304; the second steel wire 702 slides through the groove. Please refer to [link / reference]. Figure 11 The top and bottom of the second steel wire 702 are provided with spiral anti-detachment coils 701, and the second steel wire 702 is located on the top of the second rubber plug 304. The end of the lead wire 6 is wrapped and fixed to the top of the second steel wire 702. In addition to the first steel wire 7 with a U-shape, the device can also use the second steel wire 702 with anti-detachment coils 701 at both ends.

[0055] In practical operation, when the umbrella needs to be opened, the operator holds the umbrella handle 301 with one hand and the release device 8 with the other, and pulls the umbrella handle 301 downwards, causing the second umbrella rod 2 and the third umbrella rod 3 to be pulled out from the first umbrella rod 1. During the process of the second umbrella rod 2 and the third umbrella rod 3 being pulled out from the first umbrella rod 1, the third umbrella rod 3 drives the first steel wire 7 to move downwards through the second rubber plug 304 fixed at its top, thereby causing the first steel wire 7 to pull the guide wire 6 downwards. The downwardly pulled guide wire 6 drives the slider 5 to move along the outer wall of the first umbrella rod 1 to the bottom of the upper nest 4 through the fixed pulley 401. When the umbrella rib rod 403 and the connecting rod 405 are fully connected... When the umbrella is opened, the first spring 303, which is in a compressed state, is installed inside the first rubber plug 202 and the second rubber plug 304, respectively pressing the first spring 201 and the second spring 302 outward. This causes the first spring 201 to fix the first umbrella pole 1 and the second umbrella pole 2, and the second spring 302 to fix the second umbrella pole 2 and the third umbrella pole 3. Since the first umbrella pole 1, the second umbrella pole 2 and the third umbrella pole 3 are fixed together by the first spring 201 and the second spring 302, the three will not retract automatically. At this time, the taut string 6 fixes the slider 5 to the top of the first umbrella pole 1 through the movable pulley 502 inside the slider 5.

[0056] When the umbrella needs to be folded up, the operator presses the button 801 fixed to one side of the release device 8 at the bottom of the first umbrella pole 1. The button 801 pushes the first spring 201 into the first rubber stopper 202. Since the second spring 404 connecting the umbrella ribs 403 and the connecting rod 405 is always stretched when the umbrella is fully open, when the first spring 201, which is fixed between the first umbrella pole 1 and the second umbrella pole 2, retracts into the first rubber stopper 202, the stretched second spring 404 retracts the umbrella ribs 403 and the connecting rod 405 closer together. As the umbrella rib 403 and connecting rod 405 move closer together, the connecting rod 405 pushes the slider 5 connected to its end downwards, causing the slider 5 to slide vertically downwards along the first umbrella rib 1. When the slider 5 slides downwards, the movable pulley 502 inside the slider 5 drives the connecting wire 6 located outside the first umbrella rib 1 downwards. During the downward movement of the connecting wire 6 outside the first umbrella rib 1, the connecting wire 6 located inside the first umbrella rib 1 moves upwards, causing the connecting wire 6 to drive the second rubber plug 304 upwards via the first steel wire 7 connected to its end. Under the influence of the second rubber plug 304, the relative... Regarding the first umbrella pole 1, the second umbrella pole 2 and the third umbrella pole 3 move closer to the first umbrella pole 1. When the release device 8, which is fixedly installed at the bottom of the first umbrella pole 1, contacts the second spring post 302, the inner wall of the release device 8 will squeeze and retract the second spring post 302 into the interior of the second rubber plug 304, causing the third umbrella pole 3 to move into the interior of the second umbrella pole 2. When the slider 5 moves to the top wall of the release device 8, the second umbrella pole 2 retracts into the interior of the first umbrella pole 1. Since the first steel wire 7 installed at the top of the third umbrella pole 3 abuts against the bottom of the first rubber plug 202 fixed at the top of the interior of the second umbrella pole, the second umbrella pole 2 is retracted into the interior of the first umbrella pole 1. On the wall, the third umbrella pole 3 cannot be fully retracted into the second umbrella pole 2. Furthermore, the distance between the release device 8 at the bottom of the first umbrella pole 1 and the handle 301 is equal to the distance between the top wall of the second rubber plug 304 and the top of the first steel wire 7. Then, the person pushes the third umbrella pole 3 into the second umbrella pole 2 through the handle 301. When the third umbrella pole 3 moves into the second umbrella pole 2, due to the obstruction of the first rubber plug 202, the first steel wire 7 slides down along the groove 305 on the outer wall of the second rubber plug 304 until the third umbrella pole 3 is fully retracted into the second umbrella pole 2.

[0057] In other embodiments, a third spring may also be provided at the bottom of the second steel wire 702, which abuts against the bottom of the second rubber stopper 304 or separates from the bottom of the second rubber stopper 304 when the umbrella is opened or closed.

[0058] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
