Detailed Implementation

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] See Figure 1-7 As shown, in some embodiments, the foldable sun umbrella of this utility model has an unfolded state and a folded state, and includes a pole assembly, an umbrella frame structure, a flexible component 5, and an operating assembly.

[0029] The pole assembly includes a fixed rod 1 and a movable rod 2 that can be moved up and down relative to the fixed rod 1. Both the fixed rod 1 and the movable rod 2 extend in the vertical direction. Specifically, in one embodiment, the movable rod 2 is slidably inserted into the fixed rod 1 and can extend and shorten relative to the fixed rod 1.

[0030] The umbrella frame structure is positioned between the fixed rod 1 and the movable rod 2, and can be opened and closed relative to the fixed rod 1. Specifically, in one embodiment, the umbrella frame structure includes an umbrella canopy rod 3 and a support rod 4. One end of the umbrella canopy rod 3 is rotatably connected to the upper end of the movable rod 2, one end of the support rod 4 is rotatably connected to the middle of the umbrella canopy rod 3, and the other end of the support rod 4 is rotatably connected to the fixed rod 1. Figure 7 As shown, in this embodiment, there are 6 umbrella poles 3 and 6 support poles 4. In other embodiments, the number of umbrella poles 3 and support poles 4 can be set to other numbers.

[0031] The flexible element 5 is wound around the fixed rod 1 and can rotate relative to the fixed rod 1. At least a portion of the flexible element 1 is fixedly connected to the movable rod 2. In one embodiment, the flexible element 1 is a flexible rope; in other embodiments, it can be a flexible object such as a chain. The fixed rod 1 is provided with fixed pulleys, including an upper fixed pulley 11 fixedly disposed on the upper part of the fixed rod 1 and a lower fixed pulley 12 fixedly disposed on the lower part of the fixed rod 2. The flexible element 5 is wound around the fixed rod 2 in a ring via the upper fixed pulley 11 and the lower fixed pulley 12. In one embodiment, the upper fixed pulley 11 and the lower fixed pulley 12 are specifically cylindrical pins. The flexible element 5 is disposed inside the fixed rod 1. In one embodiment, a guide element 13 can also be provided inside the fixed rod 1 to separate the ring-wound flexible element 5 from the middle, preventing the flexible element 5 from tangling when rotating relative to the fixed rod 1. In one embodiment, a snap-fit ​​ring 6 is fixedly disposed on the flexible element 5. The lower end of the movable rod 2 is fixedly connected to the flexible element 5 through the engagement of a stud 7 and the snap-fit ​​ring 6.

[0032] The control component is used to switch the foldable umbrella between the open and closed states. In one embodiment, the operating component includes a slider and a handle 9. Both ends of the flexible member 5 are fixedly connected to the slider. Specifically, the two ends of the flexible member 5 can be fixedly connected to the slider via studs 7. The slider includes a slider body 81 and an abutment 82 fixedly connected to the slider body 81. The handle 9 includes a handle body 91 and a fixing member 92 fixedly connected to the handle body 91. The handle body 91 is used for user operation. The fixing member 92 is rotatably connected to the slider via a rotating shaft 10 extending in the left-right direction. A groove 14 extending in the up-down direction is provided on the fixing rod 1. The slider body 81 is engaged in the groove 14, allowing the slider to slide up and down relative to the fixing rod 1. The abutment 82 is located outside the fixing rod 1 and can engage or disengage with the fixing rod 1. Specifically, one of the fixing member 92 and the abutment 82 has a sloping protrusion 821, and the other has a mating part 921 that engages with the sloping protrusion 821. Figure 1-4As shown, in one embodiment, the abutment 82 has an annular concave surface 822 that matches the shape of the annular fixed rod 1 on the left side near the fixing rod 1. The abutment 82 has a sloping protrusion 821 and a limiting member 823 on the right side near the fixing member 1. The sloping protrusion 821 spirally protrudes outward to the right. The fixing member 92 has a mating part 921 that mates with the sloping protrusion 821 on the left side near the abutment 82. The limiting member 823 protrudes to the right and is used to restrict the rotation of the handle 9 relative to the abutment 82. Specifically, there are two limiting members 823, allowing the foldable sunshade to have a locked state and an unlocked state. Figure 3-4 As shown, when in the locked state, the handle body 91 extends vertically, and the mating part 921 of the fixing member 92 abuts against the inclined protrusion 821 of the abutment member 82 with an interference fit, thereby making the annular concave surface 822 of the abutment member 82 tightly fit against the fixing rod 1. The fixing member 92 abuts against one of the limiting members 823, preventing the user from further rotating the fixing member 92 clockwise relative to the abutment member 82. At this time, due to the friction between the abutment member 82 and the fixing rod 1, the sliding member and the handle 9 cannot slide relative to the fixing rod 1. When in the unlocked state... In the locked state, the mating part 921 of the fixing member 92 rotates away from the inclined protrusion 821 of the abutment member 82, the annular concave surface 822 of the abutment member 82 disengages from the fixing rod 1, and the fixing member 92 abuts against another limiting member 823 to prevent the user from further rotating the fixing member 92 counterclockwise relative to the abutment member 82. At this time, the sliding member can slide relative to the fixing rod 1. When switching from the locked state to the unlocked state, the user only needs to turn the handle 9 counterclockwise, and when switching from the unlocked state to the locked state, the user only needs to turn the handle 9 clockwise. Of course, in other embodiments, it can also be set so that when switching from the locked state to the unlocked state, the user only needs to turn the handle 9 clockwise, and when switching from the unlocked state to the locked state, the user only needs to turn the handle 9 counterclockwise.

[0033] like Figure 7 As shown, when in the open state, the handle 9 is positioned above the fixed rod 1, and the connection point between the flexible part 5 and the movable rod 2 is positioned below the fixed rod 1. This causes the movable rod 2 to shorten relative to the fixed rod 1, and the umbrella frame structure to move away from the fixed rod 1, i.e., open relative to the fixed rod 1. Figure 6 As shown, when in the folded state, the handle 9 is located below the fixed rod 1, and the connection point between the flexible part 5 and the movable rod 2 is located above the fixed rod 1, causing the movable rod 2 to extend relative to the fixed rod 1, and the umbrella frame structure to move closer to the fixed rod 1, that is, to fold relative to the fixed rod 1; when switching between the open and folded states, the handle 9 drives the flexible part 5 to rotate relative to the fixed rod 1, which in turn drives the movable rod 2 to move up and down relative to the fixed rod 1.

[0034] The following describes the usage method and principle of this foldable sun umbrella:

[0035] like Figure 6 As shown, the foldable parasol is in a folded and locked state at this time. The handle 9 is located below the slide groove 14 of the fixed rod 1. The handle 9 extends in the vertical direction. Due to the interference fit between the mating part 921 of the fixing member 92 and the inclined protrusion 821 of the abutment member 82, the annular concave surface 822 of the abutment member 82 is attached to the outer wall of the fixed rod 1, causing the sliding member to be unable to slide relative to the fixed rod 1. The user rotates the handle 9 counterclockwise, that is, the handle 9 rotates 90 degrees relative to the abutment member 82 around the rotation axis 10 until the limiting member 823 of the abutment member 82 prevents the mating part 921 from rotating further. The mating part 921 disengages from the inclined protrusion 821 of the abutment member 82, causing the annular concave surface 822 of the abutment member 82 to disengage from the outer wall of the fixed rod 1. At this time, Handle 9 extends horizontally. Operating handle 9 causes it to slide upwards relative to fixed rod 1, causing movable rod 2 to slide downwards relative to fixed rod 1. Umbrella rod 3 rotates upwards away from fixed rod 1 around its pivot point with movable rod 2. Support rod 4 rotates downwards around its pivot point with fixed rod 1 under the influence of umbrella rod 3. The umbrella frame structure opens relative to fixed rod 1. Operating handle 9 again causes it to rotate 90 degrees clockwise around rotating axis 10 relative to abutment 82 until the limiting member 823 of abutment 82 prevents further rotation of mating part 921. The mating part 921 and the inclined protrusion of abutment 82 are interference-fitted, causing the annular concave surface 822 of abutment 82 to fit tightly against the outer wall of fixed rod 1. At this time, handle 9 extends vertically, forming... Figure 7 The foldable parasol shown is in the open and locked position.

[0036] In the description of this utility model, the directions such as "front," "back," "left," "right," "up," and "down" are defined with reference to the direction observed by the user when using the sunshade of this utility model. Figure 3 As shown in the figure, the left side is "left", the right side is "right", the top side is "up", the bottom side is "down", and the direction perpendicular to the viewpoint is "forward" and "backward". The above definitions of directions are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
