Description

Technical Field

[0001] This utility model belongs to the field of umbrella structure, and specifically relates to a windproof umbrella with adjustable shielding area. Background Technology

[0002] Traditional umbrellas have ribs that radiate outwards to support a circular canopy. They are designed to serve a single individual, and the canopy size is fixed. However, when multiple people need to share an umbrella (such as couples taking a walk, families going out, friends traveling together, or temporarily sharing with strangers in a sudden downpour), the standard single-person canopy is insufficient and cannot effectively shield all users, resulting in some people getting wet.

[0003] While tandem or multi-person umbrellas exist on the market, their essence lies in providing a wider coverage area by increasing the canopy size. However, this introduces new problems: an excessively large canopy is inconvenient for single use, occupies too much public space, and results in a poor user experience. Furthermore, the canopy of a traditional umbrella is a complete, airtight, sealed structure. When strong winds blow against the canopy, they cannot pass through quickly, and the enormous wind pressure directly impacts the ribs, causing them to fold upwards or break. This is especially true for larger canopies, which experience greater wind resistance and are more prone to damage. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a windproof umbrella with adjustable shielding area to solve the problem that the canopy size of traditional umbrellas is fixed and not windproof.

[0005] According to the embodiments of this utility model, the following technical solution is adopted: An adjustable-area windproof umbrella includes a rib assembly and a canopy assembly. The canopy assembly includes a main canopy and an extension canopy. The extension canopy extends the coverage area of ​​the main canopy. The main canopy includes at least two sections of fabric. Multiple sections of fabric are connected sequentially from the inside to the outside to form the coverage area of ​​the main canopy. The inner and outer sides of adjacent fabric sections overlap, and ventilation gaps can be formed between adjacent fabric sections. The rib assembly includes several fixed ribs for supporting the main canopy, and the main canopy is connected to the fixed ribs. The rib assembly also includes several movable ribs for supporting the extension canopy. The movable ribs have an unfolded state and a retracted state. In the unfolded state, the movable ribs support the extension canopy as an extension of the main canopy. In the retracted state, the movable ribs drive the extension canopy to be retracted inside the main canopy.

[0006] Compared with the prior art, the present invention has the following beneficial effects: In this design, the umbrella surface is formed by setting multiple overlapping sections of umbrella fabric. The ventilation gaps between adjacent umbrella fabrics allow the air to pass through when the wind blows and deforms the umbrella fabric, thus reducing the pressure directly acting on the umbrella rib assembly.

[0007] When used by a single person, the movable umbrella ribs are folded down, utilizing only the main umbrella canopy. When it is necessary to expand the canopy size, the movable umbrella ribs are extended, increasing the coverage area of ​​the main umbrella canopy. Users can choose whether to use the extended canopy based on the number of users.

[0008] Furthermore, after the main umbrella canopy is opened, the outer edge of the inner umbrella fabric presses against the inner edge of the outer umbrella fabric.

[0009] Furthermore, several elastic bands are fixed circumferentially between adjacent umbrella fabrics.

[0010] Furthermore, the extended canopy has two sets, located on opposite sides of the main canopy.

[0011] Furthermore, the number of movable umbrella ribs is less than or equal to the number of fixed umbrella ribs, and the movable umbrella ribs are connected to the fixed umbrella ribs.

[0012] Furthermore, a mounting rod is fixed to the fixed umbrella rib, and a sliding groove is provided on the mounting rod. A slider is fixed to the movable umbrella rib, and the slider is slidably connected in the sliding groove.

[0013] Furthermore, wear-resistant layers are provided on both the slider and the groove.

[0014] Furthermore, a first connector is installed on the outermost edge of the main umbrella canopy, and second connectors for connecting with the first connector are installed on both the inner and outer sides of the extended umbrella canopy.

[0015] Furthermore, the first and second connectors are Velcro, and the second connector on the extended umbrella surface is an integral design that extends from the inside to the outside of the extended umbrella surface.

[0016] Furthermore, an umbrella pole is fixed to the center of the umbrella canopy, and the fixed umbrella ribs are all hinged to the umbrella pole. A sliding ring is slidably connected to the umbrella pole, and a support rod is hinged between the sliding ring and the fixed umbrella ribs. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings, and specific embodiments will be given. like Figure 1 As shown, the windproof umbrella with adjustable shielding area includes a rib assembly and a canopy assembly. The canopy assembly includes a main canopy 2 and an extension canopy 3. The extension canopy 3 is used to extend the shielding area of ​​the main canopy 2. An umbrella pole 4 is fixed to the center of the main canopy 2, and the free end of the umbrella pole 4 is used for hand gripping. In actual design, the umbrella pole 4 can be omitted and replaced with a headband structure of a headband umbrella in the prior art, referring to the design of the existing headband umbrella.

[0022] The main canopy 2 includes at least two sections of canopy fabric 1. These sections of fabric 1 are sequentially connected from the inside out to form the covering area of ​​the main canopy 2. Figure 3 As shown, the inner and outer sides of adjacent umbrella fabrics 1 have overlapping areas, and ventilation gaps 13 can be formed between adjacent umbrella fabrics 1. Figure 3 The dimensions shown are for illustrative purposes only. Since the umbrella fabric 1 is actually very thin, the ventilation gap 13 between two sections of fabric 1 is generally not visible, only becoming visible when subjected to external force. In actual use, to prevent leaks, after the main umbrella surface 2 is opened, the outer edge of the inner fabric 1 presses against the inner edge of the outer fabric 1. However, in strong winds, the fabric 1 deforms under stress, opening the ventilation gap 13 between adjacent fabrics, allowing wind to pass through and reducing wind pressure. Several elastic bands 14 are fixed circumferentially between adjacent fabrics 1, connecting them without affecting the opening of the ventilation gap 13 when the fabric 1 is subjected to wind. Furthermore, multiple sections of fabric 1 can share the stress, preventing excessive stress and damage to any one section of fabric 1.

[0023] In the actual design process, the shape of the extended umbrella surface 3 can be designed according to actual needs, as long as the coverage area can be expanded. In this embodiment, there are two sets of extended umbrella surfaces 3, which are located on opposite sides of the main umbrella surface 2. Since multiple people usually walk side by side when using it, the extended umbrella surfaces 3 are only set on both sides of the main umbrella surface 2. The two sets of extended umbrella surfaces 3 can be controlled to open or not, so that only one side or both sides can be opened according to the number of users.

[0024] The umbrella rib assembly includes several fixed umbrella ribs 5 for supporting the main umbrella canopy 2. The main umbrella canopy 2 is connected to the fixed umbrella ribs 5. Specifically, the multiple sections of umbrella fabric 1 of the main umbrella canopy 2 can be connected to the fixed umbrella ribs 5 by multi-point bonding or multi-point sewing. The fixed umbrella ribs 5 are all hinged to the umbrella pole 4. A sliding ring 8 is slidably connected to the umbrella pole 4. A support rod 7 is hinged between the sliding ring 8 and the fixed umbrella ribs 5. The sliding of the sliding ring 8 causes the support rod 7 to deflect, thereby opening the fixed umbrella ribs 5 and allowing the main umbrella canopy 2 to open.

[0025] In the actual design process, the opening and closing of the umbrella canopy components can be designed with reference to existing straight-handle umbrellas, such as... Figure 1 As shown, a push ring is slidably connected to the umbrella shaft 4, and a push rod is hinged between the push ring and the support rod 7. In actual operation, the sliding of the push ring causes the push rod and the support rod 7 to deflect sequentially, thus opening and closing. Existing everyday straight-handled umbrellas have a spring between the push ring and the sliding ring 8. The elastic force of the spring allows the umbrella to open automatically. Therefore, it is only necessary to install a limiting clip at the handle of the umbrella shaft 4 when the umbrella is closed to limit the push ring (refer to the pressable sliding button design at the umbrella handle in existing technology, so that the button can be inserted into the hole opened on the push ring). Alternatively, referring to the earlier oil-paper umbrella design, a spring is not used. In this case, a second limiting clip for limiting the push ring needs to be designed on the umbrella shaft 4 after the umbrella is opened.

[0026] Furthermore, the aforementioned designs are all straight-handle umbrella designs with umbrella pole 4. However, in actual design, the umbrella pole 4 can be omitted and replaced with a headband-style structure of a headband umbrella in the prior art, referring to the headband umbrella design in the prior art. This embodiment provides multiple opening and closing methods for the umbrella surface assembly, as long as the opening and closing of the umbrella surface assembly can be achieved. Even if the umbrella surface assembly is only in the open state and cannot be closed, that is, the umbrella surface assembly is stretched open by the umbrella rib assembly and cannot be closed, it does not affect the realization of the shading area adjustment and segmented wind resistance effect in this application. Therefore, the aforementioned opening and closing designs all refer to the conventional umbrella designs in the prior art. This application does not make improvements or solve related technical problems, and therefore will not be described in detail.

[0027] The umbrella rib assembly also includes several movable umbrella ribs 6 for supporting the extended umbrella surface 3. The movable umbrella ribs 6 have an unfolded state and a retracted state. In the unfolded state, the movable umbrella ribs 6 support the extended umbrella surface 3 as an extension of the main umbrella surface 2. In the retracted state, the movable umbrella ribs 6 drive the extended umbrella surface 3 to be retracted inside the main umbrella surface 2.

[0028] Specifically, the number of movable umbrella ribs 6 is less than or equal to the number of fixed umbrella ribs 5, combined with Figure 2As shown, the movable umbrella rib 6 is connected to the fixed umbrella rib 5. The movable umbrella rib 6 is installed on the fixed umbrella rib 5, and it can be retracted simultaneously when the fixed umbrella rib 5 is closed. No additional installation position needs to be designed for the movable umbrella rib 6. Figure 2 The dimensions shown are for illustrative purposes only. In reality, both the fixed umbrella rib 5 and the movable umbrella rib 6 are thin rods, and will not create the wide gaps shown in the illustration. A mounting rod 9 is fixed to the fixed umbrella rib 5, and a sliding groove is formed on the mounting rod 9. A slider 12 is fixed to the movable umbrella rib 6, and the slider 12 is slidably connected within the sliding groove. When the movable umbrella rib 6 slides relative to the fixed umbrella rib 5, the extended umbrella surface 3 slides out of the main umbrella surface 2, indicating the open state. To prevent excessive relative sliding, both the slider 12 and the sliding groove are provided with a wear-resistant layer. This wear-resistant layer can be a rubber pad bonded to it to increase friction, or it can be a wear-resistant layer obtained by sanding the surfaces of the slider 12 and the sliding groove.

[0029] In another embodiment of this utility model, a first connector 10 is installed on the outermost edge of the main umbrella surface 2, and a second connector 11 for connecting with the first connector 10 is installed on both the inner and outer sides of the extended umbrella surface 3. When the movable umbrella rib 6 is in the unfolded state, the second connector 11 on the inner side of the extended umbrella surface 3 is connected to the first connector 10, and when the movable umbrella rib 6 is in the retracted state, the second connector 11 on the outer side of the extended umbrella surface 3 is connected to the first connector 10.

[0030] Specifically, the first connector 10 and the second connector 11 are Velcro, which makes the connection process more convenient. In this embodiment, in order to improve the adjustable range of the umbrella canopy assembly's shielding area, the second connector 11 on the extended umbrella canopy 3 is an integral design that extends from the inside to the outside of the extended umbrella canopy 3. That is, when the movable umbrella rib 6 is slidable, the second connector 11 and the first connector 10 can be connected at any position within the movable range of the extended umbrella canopy 3, thereby fixing the extended umbrella canopy 3 and adjusting the shielding area of ​​the umbrella canopy assembly.
