DETAILED DESCRIPTION

[0030] The following detailed description of preferred embodiments of the present invention is provided in conjunction with the accompanying drawings to facilitate understanding of the advantages and features of the present invention by those skilled in the art. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0031] See also Figure 1-5 As shown, the automatically opening parasol of the present invention has an unfolded state and a folded state, and includes: an umbrella pole 1, a sliding assembly 2, an umbrella frame, an elastic member 35 and a support rod 4.

[0032] The sliding assembly 2 is slidably mounted on the umbrella shaft 1 along its longitudinal extension and can be locked and unlocked relative to the umbrella shaft 1. Specifically, in some embodiments, a locking slot is provided on the umbrella shaft 1. The sliding assembly 2 includes a sliding sleeve 21, a locking member (not shown), and an unlocking member 22 for controlling the locking member to disengage from the locking slot. The locking member is released from the locking slot by operating the unlocking member 22, thereby unlocking the sliding assembly 2 relative to the umbrella shaft 1. The specific method of cooperating between the unlocking member 22 and the locking member can utilize existing technologies and will not be elaborated on herein.

[0033] In some embodiments, the lock slot includes an upper lock slot 11 for locking the automatically opening parasol in an expanded state and a lower lock slot 12 for locking the automatically opening parasol in a folded state. The upper lock slot 11 has an upper inclined surface 111 that allows the locking member to slide upward relative to the lock slot and a lower blocking surface 112 that prevents the locking member from sliding downward relative to the lock slot. Figure 3 As shown, there are multiple upper locking grooves 11, so that the parasol has multiple unfolding positions in the unfolded state. The upper inclined surface 11 extends obliquely from the inside to the outside and from the bottom to the top, and the lower blocking surface 112 extends roughly in the horizontal direction. The lower locking groove 12 has a lower inclined surface 121 that allows the locking member to slide downward relative to the locking groove and an upper blocking surface 122 that prevents the locking member from sliding upward relative to the locking groove. Figure 3As shown, multiple lower locking slots 12 are provided, allowing the parasol to have multiple folded positions when folded. The lower inclined surface 121 extends from the inside to the outside and from the top to the bottom, while the upper blocking surface 122 extends generally horizontally. In one embodiment, a stopper 13 can be provided at the upper end of the upper locking slot 12 to prevent the sliding assembly 2 from sliding further upward and preventing damage.

[0034] The umbrella frame is arranged on the upper part of the umbrella pole 1, and the umbrella frame includes a plurality of top rod assemblies 3, such as Figure 1 As shown, in this embodiment, four push rod assemblies 3 are provided, as shown in FIG. Figure 5 As shown, six top rod assemblies 3 may be provided, and in some embodiments, other numbers of top rod assemblies 3 may be provided. Each top rod assembly 3 includes a first top rod 31 and a second top rod 32 disposed below the first top rod 31. The length extension direction of the first top rod 31 and the length extension direction of the second top rod 32 are arranged parallel to each other. The first top rod 31 and the second top rod 32 each have an inner end and an outer end. The inner end of the first top rod 31 and the inner end of the second top rod 32 are respectively rotatably connected to the umbrella shaft 1. In one embodiment, the umbrella shaft 1 includes an upper umbrella seat 14 and a lower umbrella seat 15. The inner end of the first top rod 31 is rotatably connected to the upper umbrella seat 14, and the inner end of the second top rod 32 is rotatably connected to the lower umbrella seat 15.

[0035] Each push rod assembly 3 is provided with at least one connecting rod located between the first push rod 31 and the second push rod 32. The connecting rod is rotatably connected to the first push rod 31 and the second push rod 32, respectively. In some embodiments, the connecting rod includes a first connecting rod 33 and a second connecting rod 34. The first connecting rod 33 is rotatably connected to the outer end of the first push rod 31 and the outer end of the second push rod 32, respectively. The second connecting rod 34 is rotatably connected to the middle portion of the first push rod 31 and the middle portion of the second push rod 32, respectively. The length extension direction of the first connecting rod 33 is parallel to the length extension direction of the second connecting rod 34. In other embodiments, each push rod assembly 3 may also be provided with only the first connecting rod 33 or the second connecting rod 34.

[0036] Each push rod assembly 3 is provided with at least one elastic member 35 located between the first push rod 31 and the second push rod 32. The elastic member 35 is connected to the first push rod 31 and the second push rod 32 respectively. In some embodiments, the elastic member 35 is a tension spring, such as Figure 1-5 As shown, the elastic members 35 in each push rod assembly 3 can be set to two symmetrically distributed ones so that the elastic force in each group of push rod assemblies 3 is more uniform. The first push rod 31 and the second push rod 32 are respectively provided with a hook pin, which protrudes from the first push rod and the second push rod to facilitate the hooking of the elastic member 35. The two ends of the elastic member 35 are respectively rotatably connected to the hook pin. In other embodiments, several groups of symmetrically distributed elastic members 35 can also be set in each group of push rod assemblies 3 in the inner and outer directions. Figure 5As shown, in each push rod assembly 3, the first push rod 31 and the second push rod 32 are hollow, each of which has a hanging pin, and the two ends of the elastic member 35 are rotatably connected to the hanging pin. At this time, the hanging position of the hanging pin and the elastic member 35 is located in the first push rod 31 and the second push rod 32. At this time, since the elastic force exerted on the first push rod 31 and the second push rod 32 is relatively uniform, there is no need to symmetrically set two elastic members. In this embodiment, two elastic members are respectively provided in the inner and outer directions. In other embodiments, each group of push rod assemblies can also be provided with only one elastic member.

[0037] One end of the support rod 4 is rotatably connected to the second push rod 32, and the other end of the support rod 4 is rotatably connected to the sliding assembly 2. Specifically, the other end of the support rod 4 is rotatably connected to the sliding seat 27 at the top of the sliding assembly 2. The number of support rods 4 corresponds to the number of push rod assemblies 2. Figure 1-4 As described above, there are 4 support rods 4, such as Figure 5 As shown, there are six support rods 4. In some embodiments, the rotational connection point between the support rod 4 and the second push rod 32 and the rotational connection point between the second connecting rod 34 and the second push rod 32 are coaxially arranged. In some embodiments, the rotational connection point between the elastic member 35 and the second push rod 32 and the rotational connection point between the second connecting rod 34 and the second push rod 32 can also be coaxially arranged. In some embodiments, the rotational connection point between the elastic member 35 and the second push rod 32 and the rotational connection point between the first connecting rod 33 and the second push rod 32 can also be coaxially arranged.

[0038] like Figure 1-2 As shown in Figure 5, when in the unfolded state, the umbrella frame is unfolded relative to the umbrella pole 1. At this time, the locking member is located in the upper locking groove 11, and the sliding assembly 2 is locked relative to the umbrella pole 1. The upper locking groove 11 prevents the sliding assembly 2 from sliding downward, but the user can push the sliding assembly 2 upward to adjust the unfolded position. The elastic member 35 is in a natural state, the elastic member 35 is contracted, and the connection point between the elastic member 35 and the second top rod 32 is located outside the connection point between the elastic member 35 and the first top rod 31, that is, the elastic member 35 extends obliquely from outside to inside and from bottom to top, and the length extension direction of the elastic member 35 is not parallel to the length extension direction of the connecting rod. Specifically, the upper end face of the elastic member 35 forms a first angle C with the connecting rod, and the first angle C is greater than 0 degrees and less than 90 degrees.

[0039] like Figure 4 As shown, when in the folded state, the umbrella frame is folded relative to the umbrella pole 1, the locking member is located in the lower locking groove 12, the sliding assembly 2 is locked relative to the umbrella pole 1, and the lower locking groove 12 prevents the sliding assembly 2 from sliding upward, but the user can push the sliding assembly 2 downward to adjust the folded position. The elastic member 35 is in a deformed state and accumulates elastic force. Specifically, the elastic member 35 stretches.

[0040] When switching from the folded state to the unfolded state, the user can operate the pressing portion 233, the sliding assembly 2 is unlocked relative to the umbrella pole 1, and the elastic member 35 pulls the umbrella frame to open relative to the umbrella pole 1, providing the elastic force required for the sliding assembly 2 to slide from bottom to top along the umbrella pole 1, thereby automatically opening the parasol. When the sliding assembly 2 moves until the locking member is close to the upper locking groove 11, the user can further push the sliding assembly 2 upward to complete the locking of the sliding assembly 2 relative to the umbrella pole 1.

[0041] When switching from the unfolded state to the folded state, the user can press the pressing portion 233 to unlock the sliding assembly 2 relative to the umbrella pole 1. Due to the effect of gravity, the user only needs to gently pull the sliding assembly 2 downward to fold the umbrella frame relative to the umbrella pole 1. The user does not need to press the unlocking member 23, but only needs to pull the sliding assembly 2 downward until it engages with the lower locking groove 12 to complete the locking of the sliding assembly 2 relative to the umbrella pole 1.

[0042] In other embodiments, the elastic member 35 may also be a compression spring (not shown in the figure). When the elastic member 35 is set as a compression spring, the main difference between it and the elastic member 35 set as a tension spring is that when in the expanded state, the elastic member 35 extends, and the connection point between the elastic member 35 and the second push rod 32 is located on the inner side of the connection point between the elastic member and the first push rod 31, that is, the compression spring extends obliquely from the inside to the outside and from the bottom to the top, and the length extension direction of the elastic member 35 is not parallel to the length extension direction of the connecting rod. Specifically, the lower end face of the elastic member 35 forms a second angle with the connecting rod (not shown in the figure), and the second angle is greater than 0 degrees and less than 90 degrees. When in the folded state, the elastic member contracts. When switching from the folded state to the expanded state, the compression spring releases the elastic force to push the umbrella frame to expand relative to the umbrella pole 1.

[0043] In the description of the present invention, the directions involved such as "front", "back", "left", "right", "up", and "down" are defined with reference to the directions observed by the user when using the automatically opening parasol, that is, Figure 2 As shown in the figures, the left direction in the figures is "left", the right direction in the figures is "right", the upper direction in the figures is "up", the lower direction in the figures is "down", the directions perpendicular to the viewing angle in the figures are "front" and "back", and the direction from inside to outside refers to the direction extending from close to the umbrella pole to away from the umbrella pole. The definitions of the above directions are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention.
