Description

Technical Field

[0001] This utility model relates to the field of umbrella canopy, and more particularly to a modular extended umbrella canopy. Background Technology

[0002] Existing umbrellas have a fixed size and are usually only suitable for one person to use. When more than two people use them, they cannot take care of everyone, resulting in someone always getting wet. Furthermore, even though they are only for single-person use during heavy rain, the person holding the umbrella will still get wet due to the heavy rainfall.

[0003] To overcome the above shortcomings, existing technologies have proposed a folding umbrella whose area can be adjusted independently according to actual needs. For example, Chinese patent application number CN201320794174.0 mentions a folding umbrella that can change size, including an umbrella handle, a main umbrella canopy, and multiple main umbrella ribs fixed under the main umbrella canopy and connected to the top of the umbrella handle. A folding umbrella canopy extends along the outer edge of the main umbrella canopy. Multiple folding umbrella ribs are provided under the folding umbrella canopy, with the same number and corresponding positions as the main umbrella ribs. The folding umbrella ribs are hinged to the main umbrella ribs through a pivot. A spring is sleeved on the pivot. One end of the spring is fixed inside the main umbrella rib, and the other end is fixed inside the folding umbrella rib. A pull cord is fixed to the outer edge of the folding umbrella rib. The pull cord passes through the outer side of the folding umbrella rib and the inner side of the main umbrella rib in sequence, enters from the top of the umbrella handle, and then connects to the movable handle at the bottom of the umbrella handle.

[0004] As described in the aforementioned patent, existing technologies typically employ a hinged design of the main umbrella ribs and folding umbrella ribs to adjust the size of the umbrella canopy. However, existing technologies have the following problems: compared to traditional fixed-size umbrellas, the structure of this variable-size umbrella is more complex, and components such as springs and drawstrings may fail due to fatigue after long-term use, requiring regular inspection and replacement, and the manufacturing and maintenance costs may be high; when the umbrella is closed, due to the addition of folding umbrella ribs and drawstrings, the overall volume of the umbrella may be larger than that of a regular umbrella.

[0005] In conclusion, there is a need for a modular extended umbrella canopy that is simple, durable, and easy to store. Utility Model Content

[0006] To address the problems of complex structure, high maintenance costs, and excessively large umbrella volume when folded in existing variable-size umbrellas, this utility model proposes a modular expandable umbrella surface, as follows.

[0007] A modular extended umbrella canopy includes several mounting rods and an umbrella fabric. Each mounting rod has a locking mechanism for locking the umbrella fabric and mounting clips for fixing the mounting rods to the umbrella ribs. The umbrella fabric has a central opening for the umbrella rods to pass through. The mounting rods are evenly arranged around the axis of the umbrella rods, and each mounting rod is parallel to the axis of the umbrella rib it is fixed to. Several mounting fabric tubes are evenly arranged around the axis of the umbrella rods on the umbrella fabric, and the mounting rods can be coaxially inserted into the mounting fabric tubes. The locking mechanism includes several pairs of locking plates on the mounting rods. Each pair of locking plates includes a female plate and a male plate, located at opposite ends of the mounting fabric tubes. One end of each female and male plate is hinged to a mounting rod, and the planes of rotation of the female and male plates are parallel to the axis of the mounting rods. The female and male plates are fixedly connected by an interlocking structure, thereby locking the umbrella fabric. The mounting clips are mounted on the mounting rods and can radially clamp the umbrella ribs.

[0008] Furthermore, the umbrella fabric is composed of several isosceles trapezoidal fabric blocks whose sides are spliced ​​together, that is, a pair of corresponding waist edges of every two isosceles trapezoidal fabric blocks are connected in a collinear manner to form a seam, and a regular polygonal cutout is formed in the middle of several isosceles trapezoidal fabric blocks.

[0009] Furthermore, several of the installation sleeves are arranged along the joint, with their axes parallel to the joint.

[0010] Furthermore, the interlocking structure includes a spherical protrusion on the male piece and a fixing groove formed by bending the female piece itself. The locking piece is made of an elastic material, and the spherical protrusion can be inserted into the fixing groove, thereby locking the male and female pieces together.

[0011] Furthermore, the mounting rod is provided with several receiving grooves along the axial direction, and several movable shafts perpendicular to the side wall of the receiving groove are provided in the receiving grooves. One end of the male and female pieces are respectively hinged in the receiving grooves through a movable shaft.

[0012] Furthermore, the mounting clamp comprises a pair of clamping plates symmetrically arranged on both sides of the mounting rod. The clamping plates are coaxially rotatably mounted on the mounting rod via a bearing seat on the side of the plate closest to the mounting rod. The clamping plates are coaxially rotatably mounted on the area of ​​the mounting rod not covered by the mounting cloth sleeve via the bearing seat. A torsion spring is coaxially arranged on the mounting rod between the pair of clamping plates. The two ends of the torsion spring are respectively fixed to the inner sides of the two clamping plates, so that the clamping plates remain in a closed clamping state without external force.

[0013] Furthermore, the end of the clamping plate away from the mounting rod is bent to form an arc-shaped clamping part, namely a first arc-shaped clamping part and a second arc-shaped clamping part. The arc radius of the first arc-shaped clamping part is greater than that of the second arc-shaped clamping part. The first arc-shaped clamping part extends further along the arc-shaped contour to form a covering section, which overlaps the outer side of the arc-shaped plate of the opposite clamping plate.

[0014] Furthermore, the inner surface of the covering section and the inner and outer surfaces of the second arc-shaped clamping part are both provided with anti-slip stripes.

[0015] Furthermore, the diameter of the portion of the mounting rod where the mounting clip is located is smaller than the diameter of the other portions of the mounting rod.

[0016] Furthermore, a clearance opening is provided on the umbrella fabric corresponding to the mounting clip position, allowing a portion of the mounting clip away from the arc-shaped clamping part to protrude from the clearance opening. The clearance opening is provided with a waterproof cover, the waterproof cover being sewn to the clearance opening around its perimeter and capable of accommodating the portion of the mounting clip protruding from the clearance opening.

[0017] This utility model has the following advantages: the mounting rod and the umbrella fabric are coaxially inserted, eliminating the need for additional folding of umbrella ribs or pull cords during folding; the umbrella surface can be layered and stacked, reducing storage space; the locking plate is stored in the receiving groove of the mounting rod via a movable shaft, facilitating the insertion of the mounting rod into the mounting fabric tube; the clamping plate automatically closes via a torsion spring to accommodate umbrella ribs of different diameters; and as long as the number and size of the umbrella ribs meet the requirements, this modular extended umbrella surface can be used, eliminating the need to produce special umbrellas to fit this modular extended umbrella surface, thus providing strong versatility and solving the problems of complex structure, high maintenance costs, and difficulty in storage in existing technologies; the interlocking structure of the locking plate, combined with the elastic material design, effectively resists the risk of loosening under vibration and humid conditions; the vertical lines of the anti-slip stripes and the double-curvature arc-shaped clamping part enhance the clamping friction of the umbrella ribs, preventing slippage under wind load.

[0024] The present invention will now be described in conjunction with the accompanying drawings:

[0025] like Figure 1 , Figure 3 , Figure 5 As shown, a modular extended umbrella canopy includes several mounting rods 1 and an umbrella fabric. The mounting rods 1 are provided with a locking mechanism for locking the umbrella fabric, and a mounting clip 7 for fixing the mounting rods 1 to the umbrella ribs 24.

[0026] like Figure 1 , Figure 2 As shown, the umbrella fabric has a hollow opening in the center for the umbrella rod 3 to pass through.

[0027] like Figure 1 , Figure 5 As shown, several mounting rods 1 are evenly arranged around the axis of the umbrella rod 3, and each mounting rod 1 is parallel to the axis of the umbrella rib 24 to which it is fixed.

[0028] like Figure 1 , Figure 3 Several mounting sleeves 4 are evenly arranged around the axis of the umbrella rod 3 on the umbrella fabric, and the mounting rod 1 can be coaxially inserted into the mounting sleeve 4.

[0029] like Figure 3 , Figure 4 As shown, the locking mechanism includes several pairs of locking plates on the mounting rod 1. Each pair of locking plates includes a female plate 5 and a male plate 6. The female plate 5 and the male plate 6 are located at both ends of the mounting fabric tube 4, and one end of each of the female plate 5 and the male plate 6 is hinged to the mounting rod 1. The rotation plane of the female plate 5 and the male plate 6 is parallel to the axis of the mounting rod 1. The female plate 5 and the male plate 6 can be fixedly connected by an interlocking structure, thereby locking the umbrella fabric.

[0030] like Figure 3 , Figure 5 As shown, the mounting clip 7 is mounted on the mounting rod 1, and the mounting clip 7 can radially clamp the umbrella rib 24.

[0031] like Figure 2 As shown, preferably, the umbrella fabric is composed of several isosceles trapezoidal fabric blocks 8 with their sides spliced ​​together, that is, the corresponding waist edges of every two isosceles trapezoidal fabric blocks 8 are connected in a collinear manner to form a seam 10, and a regular polygonal cutout is formed in the middle of several isosceles trapezoidal fabric blocks 8 so that the umbrella pole 3 can pass through it.

[0032] like Figure 1 , Figure 2 , Figure 3As shown, preferably, a plurality of the installation sleeves 4 are arranged along the seam 10, with their axes parallel to the seam 10. The installation sleeves 4 are arranged along the fabric splicing seam 10 to indirectly reinforce the seam 10 area and improve the tensile strength of the stitching.

[0033] like Figure 4 As shown, preferably, the interlocking structure includes a spherical protrusion 11 on the male piece 6 and a fixing groove 12 formed by bending the female piece 5 itself. The locking piece is made of elastic material. The spherical protrusion 11 can be inserted into the fixing groove 12, thereby locking the male piece 6 and the female piece 5 together. The spherical protrusion 11 of the elastic locking piece forms an interference fit with the groove. It compensates for errors through elastic deformation, resists vibration and loosening by external force, and is easy to operate. It can be locked by simply pressing or flipping.

[0034] like Figure 4 As shown, preferably, the mounting rod 1 has a plurality of receiving grooves 13 along the axial direction, and a plurality of movable shafts 14 perpendicular to the side wall of the receiving groove 13 are provided in the receiving grooves 13. One end of each of the male piece 6 and the female piece 5 is hinged to a different receiving groove 13 through a movable shaft 14. The locking piece is hinged to the movable shaft 14 and is completely embedded inside the mounting rod 1 when folded up, reducing the risk of scratching by external protruding parts and making the umbrella surface flatter after folding.

[0035] like Figure 3 , Figure 5 As shown, preferably, the mounting clamp 7 comprises a pair of clamping plates 15 symmetrically arranged on both sides of the mounting rod 1. The clamping plates 15 are coaxially rotatably mounted on the mounting rod 1 via a bearing 16 on the side of their plates near the mounting rod 1. The clamping plates 15 are coaxially rotatably mounted on the mounting rod 1 in the area not covered by the mounting cloth tube 4. A torsion spring 17 is coaxially arranged on the mounting rod 1 between the pair of clamping plates 15. The two ends of the torsion spring 17 are respectively fixed to the inner sides of the two clamping plates 15, so that the clamping plates 15 remain in a closed clamping state without external force. The torsion spring 17 drives the clamping plates 15 to close automatically, adapting to umbrella ribs 24 of different diameters, avoiding manual adjustment errors. The clamping ends are arranged in the area not covered by the cloth tube to prevent mutual interference.

[0036] like Figure 5 As shown, preferably, the end of the clamping plate 15 away from the mounting rod 1 is bent to form an arc-shaped clamping part, namely a first arc-shaped clamping part 18 and a second arc-shaped clamping part 19. The arc radius of the first arc-shaped clamping part 18 is larger than that of the second arc-shaped clamping part 19. The first arc-shaped clamping part 18 extends further along the arc contour to form a covering section 20. The covering section 20 overlaps the outer side of the arc-shaped plate of the opposite clamping plate 15. The difference in arc radius between the two clamping plates 15 forms a complementary contact surface, increasing the contact area with the umbrella rib 24. The overlapping of the covering section 20 further restricts the axial displacement of the umbrella rib 24.

[0037] like Figure 5 As shown, preferably, the inner surface of the covering section 20 and the inner and outer surfaces of the second arc-shaped clamping part 19 are provided with anti-slip stripes 21.

[0038] like Figure 3 , Figure 5 As shown in the preferred embodiment, the diameter of the part of the mounting rod 1 with the mounting clip 7 is smaller than the diameter of the other parts of the mounting rod 1, so that the mounting clip 7 cannot move axially.

[0039] like Figure 3 , Figure 5 As shown, preferably, a relief opening 22 is provided on the umbrella fabric corresponding to the position of the mounting clip 7, allowing a portion of the mounting clip 7 away from the arc-shaped clamping part to protrude from the relief opening 22. The relief opening 22 is provided with a waterproof cover 23, which is sewn to the relief opening 22 around its perimeter and can accommodate the portion of the mounting clip 7 protruding from the relief opening 22, thus maintaining the integrity of the umbrella fabric and preventing water seepage.

[0040] It should also be noted that modular extended canopies of different specifications can be produced according to size and number of ribs.

[0041] The method of using this utility model is as follows:

[0042] Open the umbrella to which this modular extended canopy needs to be installed. Fix the mounting rod 1 to the umbrella rib 24 using the mounting clip 7, ensuring that the mounting rod 1 is parallel to the axis of the umbrella rib 24 and evenly distributed around the umbrella shaft 3. Ensure that the clamping plate 15 closes and clamps the umbrella rib 24 under the action of the torsion spring 17. The arc-shaped clamping part restricts the displacement of the umbrella rib 24 by the overlap of the anti-slip stripes 21 and the covering section 20. Insert the perforated opening of the umbrella fabric into the umbrella shaft 3, and insert the mounting fabric tubes 4 distributed along the seam 10 into the mounting rod 1. This allows the male piece 6 and female piece 5, hinged in the receiving groove 13 on the mounting rod 1, to rotate and unfold around the movable axis 14. By pressing or flipping, the spherical protrusion 11 of the male piece 6 and the fixing groove 12 of the female piece 5 form an interference fit, and the locking is completed by elastic deformation. The umbrella fabric is fixed to the mounting rod 1 by the locking piece. The waterproof cover 23 covers the protruding part of the mounting clip 7 at the umbrella fabric relief opening 22 to prevent water leakage and maintain the integrity of the umbrella surface. After installation, this modular extended umbrella surface should be located below the main umbrella body, that is, the umbrella used by the user, and the modular extended umbrella surface protrudes from the space covered by the main umbrella body. This modular extended umbrella surface can only be used for umbrellas with an unfolded area smaller than the modular extended umbrella surface.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
