Description

Technical Field

[0001] This utility model belongs to the field of Roman umbrella technology and relates to a wind-resistant structure for Roman umbrellas. Background Technology

[0002] Since Roman umbrellas are used outdoors, wind resistance is a key performance factor to consider, and current improvements in wind resistance usually involve increasing the thickness of the support rods in the umbrella frame.

[0003] For example, Chinese patent application [Authorization Announcement No.: CN220587667U] discloses a Roman umbrella support structure, including a mounting bracket, a support rod, and tie rods symmetrically arranged at both ends of the support rod. One end of the tie rod is connected to the mounting bracket, and the other end is connected to the support rod. The tie rod is rotatably connected to the mounting bracket and the support rod. An inclined rod is provided at the upper end of the mounting bracket, with one end of the inclined rod located at the top of the mounting bracket and the other end located above the support rod. A rotating component is provided at the connection between the inclined rod and the mounting bracket, and a sliding component is provided at the connection between the inclined rod and the support rod.

[0004] The above structure uses an additional diagonal brace, with one end hinged to the mounting bracket and the other end hinged to the support rod. In other words, it uses a tie rod and a diagonal brace. However, in windy weather, simply strengthening the connection between the support rod and the mounting bracket will not significantly improve the wind resistance of the umbrella frame, and the wind resistance performance of the umbrella frame is limited. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a wind-resistant structure for Roman umbrellas. The technical problem this invention aims to solve is: how to address the poor wind resistance of existing Roman umbrellas during normal use.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A wind-resistant structure for a Roman umbrella includes an upper umbrella disc, an umbrella column, a pull rod hinged at its upper end to the umbrella column, and a main diagonal rod slidably connected to the umbrella column at its lower end. The lower end of the pull rod is hinged to the middle of the main diagonal rod. The upper umbrella disc includes a vertically arranged connecting rod and an umbrella disc portion hinged to the upper end of the main diagonal rod. The lower end of the connecting rod is fixedly connected to the umbrella disc portion. The wind-resistant structure includes a telescopic rod one hinged to the connecting rod and a telescopic rod two hinged to the pull rod. The hinge point of the telescopic rod one and the connecting rod is located above the hinge point of the main diagonal rod and the umbrella disc portion. The lower end of the telescopic rod one is slidably sleeved with the upper end of the telescopic rod two. A locking structure is provided between the telescopic rod one and the telescopic rod two to prevent the telescopic rod one from disengaging from the telescopic rod two when the umbrella is open.

[0008] The upper umbrella tray includes a connecting rod and an umbrella tray section. The lower end of the connecting rod is fixedly connected to the umbrella tray section. The lower end of the main inclined rod is slidably connected to the umbrella upright, and the upper end is hinged to the umbrella tray section. By adding a telescopic rod one and a telescopic rod two, the lower end of telescopic rod one is slidably connected to the upper end of telescopic rod two, and the upper end of telescopic rod one is hinged to the connecting rod. The lower end of telescopic rod two is hinged to the middle of the pull rod. Thus, the upper umbrella tray is connected to the umbrella upright and the pull rod via the main inclined rod and telescopic rods one and two respectively. To avoid affecting the opening and closing of the umbrella, telescopic rods one and two are designed to slide relative to each other. Furthermore, in the open umbrella state, to improve positioning, a locking structure is provided between telescopic rods one and two to prevent telescopic rod one from axially disengaging from telescopic rod two. This allows telescopic rods one and two to extend with the opening of the umbrella, and the locking structure provides axial limitation during opening, improving the stability of telescopic rods one and two in the open umbrella state. The locking structure between the two telescopic rods, along with the hinges at one end and the other end, provides a three-point positioning method to ensure the axial positioning of the first and second telescopic rods when the umbrella is open. This method stably improves the wind resistance performance in the circumferential direction of the main diagonal rod. Furthermore, this positioning method can be quickly released when the umbrella is retracted, ensuring that the first and second telescopic rods do not affect the closure of the Roman umbrella. The upper umbrella plate is not only connected to the umbrella column via the main diagonal rod but also via the first and second telescopic rods and the pull rod, increasing the connection points of the upper umbrella plate and further enhancing the wind resistance performance of the umbrella frame. Therefore, by using the mutually sliding and telescopically collapsible first and second telescopic rods, the connection strength between the upper umbrella plate and the pull rod is improved without affecting the use of the Roman umbrella. This makes the connection between the upper umbrella plate and the pull rod, as well as between the upper umbrella plate and the main diagonal rod, more stable, further improving the wind resistance performance of the Roman umbrella.

[0009] In this case, one or more pull rods can be installed, both of which can achieve a good connection effect. The lower end of the first telescopic rod can be inserted into the second telescopic rod or sleeved on the second telescopic rod.

[0010] In the wind-resistant structure of the Roman umbrella described above, there are two pull rods. The lower ends of the two pull rods are respectively located on the left and right sides of the main diagonal rod and are hinged to the main diagonal rod. The lower end of the auxiliary telescopic rod is located between the two pull rods and is hinged to the pull rod.

[0011] The double tie rod setup enhances the connection strength between the telescopic rod 2 and the tie rod, as well as between the main diagonal rod and the tie rod, thereby improving the wind resistance of the Roman umbrella. Furthermore, by placing the main diagonal rod and the telescopic rod 2 between the two tie rods, the synchronization between the two when they swing is improved.

[0012] In the wind-resistant structure of the Roman umbrella described above, a connecting block is fixedly connected to the middle of each of the pull rods, and the lower end of the telescopic rod two is hinged to the two connecting blocks by a screw and a nut.

[0013] By adding a connecting block, the overall shape and structure of the tie rod are not changed. The addition of the connecting block and the connection through screw one and nut one enable a quick connection between the telescopic rod two and the tie rod, improving the stability of the connection between the tie rod and the telescopic rod two while ensuring the structural strength of the tie rod itself.

[0014] In the wind-resistant structure of the Roman umbrella described above, the connecting block includes a sleeve portion that is sleeved on the pull rod. The sleeve portion protrudes downward to form a U-shaped plate-shaped connecting portion. The two connecting portions are close to each other at one end, which is a plate-shaped fixing portion that closes the opening at that end. The screw passes through the two fixing portions and is threadedly connected to the nut. The end of the screw and the nut are respectively located in the corresponding connecting portions.

[0015] By designing the shape of the connecting block, it is possible to connect the pull rod and the telescopic rod 2, while also ensuring that the end of the screw 1 and the nut 1 are hidden within the corresponding connecting parts. This does not affect the opening of the entire umbrella frame and also achieves a better connection effect, improving stability and thus ensuring the improved wind resistance of the Roman umbrella.

[0016] In the wind-resistant structure of the Roman umbrella described above, the locking structure includes a plug inserted into the lower end of the telescopic rod and a sleeve fitted onto the upper end of the telescopic rod. The end of the plug extending out of the telescopic rod has a limiting flange protruding radially outward, and the end of the sleeve extending out of the telescopic rod is a constricted end that contracts radially inward. The limiting flange can slide into the constricted end and abut against the inner wall of the constricted end axially.

[0017] By adding plugs and sleeves, the limiting edge slides into the constricted end as the umbrella frame opens when the umbrella is in the open state. The limiting edge abuts against the constricted end along the axial direction, achieving axial positioning between telescopic pole one and telescopic pole two. This prevents telescopic pole one and telescopic pole two from sliding relative to each other axially when the wind is strong, thus improving the stability of telescopic pole one and telescopic pole two. Furthermore, the addition of plugs and sleeves makes the installation and production of telescopic pole one and telescopic pole two more convenient, reducing processing costs and installation difficulty while improving stability and wind resistance.

[0018] In the wind-resistant structure of the Roman umbrella described above, both the end cap and the sleeve are square, the limiting stop can slide along the inner wall of the telescopic rod two, and the constricted end can be close to the outer wall of the telescopic rod one.

[0019] By adopting a square design, the circumferential torsional gap between telescopic pole one and telescopic pole two is minimized, thereby improving the wind resistance of both telescopic pole one and telescopic pole two. Furthermore, when the umbrella is not fully open, the constricted end and the limiting edge can play a guiding role, thus improving the wind resistance of the Roman umbrella while also increasing the installation accuracy.

[0020] In the wind-resistant structure of the Roman umbrella described above, the locking structure includes an elastic retaining ring embedded in the inner wall of the upper end of the telescopic rod and a plug inserted into the lower end of the telescopic rod. The end of the plug extending out of the telescopic rod has a limiting edge that protrudes radially outward. In the open state, the limiting edge abuts against the elastic retaining ring along the axial direction of the telescopic rod.

[0021] By directly embedding an elastic retaining ring on the inner side wall of the upper end of the telescopic pole two, the installation is simpler and the length limitation of the telescopic pole two does not need to be very precise. Only the position of the elastic retaining ring inside the telescopic pole two needs to be adjusted, making the overall structure simple and the positioning stable.

[0022] In the wind-resistant structure of the Roman umbrella described above, a tubular connecting sleeve is fitted onto the connecting rod. The connecting sleeve has two radially protruding, plate-shaped hinge parts, which are arranged in parallel. The upper end of the telescopic rod is embedded between the two hinge parts and is hinged by a screw and a nut.

[0023] The hinged part limits the upper end of the telescopic pole along the circumference, allowing it to swing in only one direction, thus improving the stability of the telescopic pole connection and further enhancing its wind resistance.

[0024] In the wind-resistant structure of the Roman umbrella described above, the telescopic rod one and the end cap, as well as the telescopic rod two and the end cap, are all connected by bolts.

[0025] This structure simplifies the connection and positioning between the first telescopic rod and the plug, as well as between the second telescopic rod and the plug sleeve, making installation convenient.

[0026] In the wind-resistant structure of the Roman umbrella described above, the telescopic rod one and the end cap, as well as the telescopic rod two and the end cap, are connected by elastic snap fasteners.

[0027] This connection method makes the connection between telescopic rod one and the plug, as well as between telescopic rod two and the plug sleeve, convenient and easy to position.

[0028] Compared with existing technologies, the wind-resistant structure of this Roman umbrella has the following advantages:

[0029] 1. By setting up telescopic poles 1 and 2 that can slide relative to each other, and in the open umbrella state, to improve the positioning effect, a locking structure is set between telescopic poles 1 and 2 to prevent telescopic pole 1 from axially disengaging from telescopic pole 2. This allows telescopic poles 1 and 2 to extend with the umbrella, and the locking structure provides axial limitation during umbrella opening. This three-point positioning method, combined with the hinges at the ends of telescopic poles 1 and 2, ensures the axial positioning of telescopic poles 1 and 2 in the open umbrella state. This can stably improve the wind resistance performance of the main inclined pole in the circumferential direction. Furthermore, this positioning method can be quickly released when the umbrella is retracted, so that telescopic poles 1 and 2 do not affect the closing of the Roman umbrella.

[0030] 2. By adding plugs and sleeves, the limiting stop edge slides into the constricted end as the umbrella frame opens when the umbrella is in the open state. The limiting stop edge abuts against the constricted end along the axial direction, achieving axial positioning between telescopic pole one and telescopic pole two. This prevents telescopic pole one and telescopic pole two from sliding relative to each other in strong winds, thus improving the stability of telescopic pole one and telescopic pole two. Furthermore, the addition of plugs and sleeves makes the installation and production of telescopic pole one and telescopic pole two more convenient, reducing processing costs and installation difficulty while improving stability and wind resistance.

[0039] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0040] Example 1

[0041] like Figure 1 As shown, the wind-resistant structure of this Roman umbrella includes an upper umbrella plate 1, an umbrella column 2, a pull rod 3 with its upper end hinged to the umbrella column 2, and a main diagonal rod 4 with its lower end slidably connected to the umbrella column 2. The lower end of the pull rod 3 is hinged to the middle of the main diagonal rod 4.

[0042] Specifically, such as Figure 1-3 As shown, the upper umbrella plate 1 includes a connecting rod 11 arranged vertically and an umbrella plate portion 12 hinged to the upper end of the main inclined rod 4. The lower end of the connecting rod 11 is fixedly connected to the umbrella plate portion 12. This wind-resistant structure includes a telescopic rod 5 hinged to the connecting rod 11 and a telescopic rod 6 hinged to the pull rod 3. The hinge point of the telescopic rod 5 and the connecting rod 11 is located above the hinge point of the main inclined rod 4 and the umbrella plate portion 12. The lower end of the telescopic rod 5 is slidably sleeved with the upper end of the telescopic rod 6. A locking structure 7 is provided between the telescopic rod 5 and the telescopic rod 6 to prevent the telescopic rod 5 from disengaging from the telescopic rod 6 when the umbrella is open.

[0043] The upper umbrella plate 1 includes a connecting rod 11 and an umbrella plate part 12. The lower end of the main inclined rod 4 is slidably connected to the umbrella support column 2, and the upper end is hinged to the umbrella plate part 12. By adding a telescopic rod 1 5 and a telescopic rod 2 6, the lower end of the telescopic rod 1 5 is slidably connected to the upper end of the telescopic rod 2 6, and the telescopic rod 1 5 is hinged to the connecting rod 11. One end of the telescopic rod 2 6 is hinged to the middle of the pull rod 3, so that the upper umbrella plate 1 is connected to the umbrella support column 2 and the pull rod 3 respectively through the main inclined rod 4, the telescopic rod 1 5, and the telescopic rod 2 6. 3. To ensure proper opening and closing of the umbrella, two relatively sliding telescopic rods, 5 and 6, are incorporated. Furthermore, to enhance positioning in the open umbrella state, a locking structure 7 is installed between telescopic rods 5 and 6 to prevent them from axially disengaging. This allows telescopic rods 5 and 6 to extend with the umbrella and provides axial restraint during opening via the locking structure 7, thus improving the connection between them in the open umbrella state. The locking structure 7, together with the hinges at the ends of telescopic rod 5 and telescopic rod 6, provides a three-point positioning method to ensure the axial positioning of telescopic rods 5 and 6 when the umbrella is open. This method can stably improve the wind resistance performance in the circumferential direction of the main diagonal rod 4. Furthermore, this positioning method can be quickly released when the umbrella is retracted, so that telescopic rods 5 and 6 do not affect the closing of the Roman umbrella. The upper umbrella plate 1 is not only connected to the umbrella column 2 through the main diagonal rod 4, but also to the umbrella column 2 through telescopic rods 5, 6, and the pull rod 3, increasing the connection points of the upper umbrella plate 1 and further improving the wind resistance performance of the umbrella frame. Therefore, by setting telescopic rods 5 and 6 that can slide and telescopically connect with each other, the connection strength between the upper umbrella plate 1 and the pull rod 3 is improved without affecting the use of the Roman umbrella. This makes the connection between the upper umbrella plate 1 and the pull rod 3, as well as between the upper umbrella plate 1 and the main diagonal rod 4, more stable and further improves the wind resistance performance of the Roman umbrella.

[0044] In this case, one or more pull rods 3 can be set, both of which can achieve a good connection effect. The lower end of the telescopic rod 5 can be inserted into the telescopic rod 6 or sleeved on the telescopic rod 6.

[0045] like Figure 2 and Figure 3 As shown, the locking structure 7 includes a plug 71 inserted into the lower end of the telescopic rod 5 and a sleeve 72 sleeved on the upper end of the telescopic rod 6. The end of the plug 71 extending out of the telescopic rod 5 has a limiting flange 71a that protrudes radially outward. The end of the sleeve 72 extending out of the telescopic rod 6 is a constricted end 72a that contracts radially inward. In the open state, the limiting flange 71a can slide into the constricted end 72a and abut against the inner wall of the constricted end 72a axially. Both the plug 71 and the sleeve 72 are square. The limiting flange 71a can slide along the inner wall of the telescopic rod 6, and the constricted end 72a can be close to the outer wall of the telescopic rod 5.

[0046] like Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, there are two pull rods 3. The lower ends of the two pull rods 3 are respectively located on the left and right sides of the main inclined rod 4 and are hinged to the main inclined rod 4. The lower end of the telescopic rod 6 is located between the two pull rods 3 and is hinged to the pull rods 3. A connecting block 8 is fixedly connected to the middle of each pull rod 3. The lower end of the telescopic rod 6 is hinged to the two connecting blocks 8 through a screw 9 and a nut 91. The connecting block 8 includes a sleeve part 81 sleeved on the pull rod 3. The sleeve part 81 protrudes downward to form a U-shaped plate-shaped connecting part 81a. The two connecting parts 81a are close to each other at one end, which is a plate-shaped fixing part 81b that closes the opening at that end. The screw 9 passes through the two fixing parts 81b and is threadedly connected to the nut 91. The end of the screw 9 and the nut 91 are respectively located in the corresponding connecting part 81a.

[0047] like Figure 1 and Figure 6 As shown, a tubular connecting sleeve 10 is sleeved on the connecting rod 11. The connecting sleeve 10 has two radially protruding, plate-shaped hinge portions 101. The two hinge portions 101 are arranged in parallel. The upper end of the telescopic rod 5 is embedded between the two hinge portions 101 and is hinged by a screw 102 and a nut 103.

[0048] like Figure 2 and Figure 3 As shown, the telescopic rod 5 and the plug 71, as well as the telescopic rod 6 and the plug 72, are connected by bolts 104.

[0049] Example 2

[0050] The content of this embodiment is basically the same as that of embodiment one, except that the locking structure 7 includes an elastic retaining ring embedded in the inner side wall of the upper end of the telescopic rod 2 6 and a plug 71 inserted into the lower end of the telescopic rod 1 5. The end of the plug 71 outside the telescopic rod 1 5 has a limiting stop edge 71a that protrudes outward in the radial direction. In the umbrella-opening state, the limiting stop edge 71a abuts against the elastic retaining ring along the axial direction of the telescopic rod 1 5.

[0051] Example 3

[0052] The content of this embodiment is basically the same as that of embodiment one, except that the telescopic rod 5 and the plug 71, as well as the telescopic rod 6 and the plug sleeve 72, are connected by elastic buckles.

[0053] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
