Description

Technical Field

[0001] The invention relates to an umbrella structure, in particular to a straight rib type automatic opening and closing umbrella rib structure. Background Art

[0002] An umbrella is a tool that provides a cool environment or shelters from rain and snow. It is an indispensable item in life and has been continuously improved and invented to make it more convenient to use and carry. Umbrellas are generally composed of umbrella cloth and umbrella ribs. The straight-bone type automatic opening and closing umbrella rib structure on the market can generally only meet one of the automatic opening or automatic closing when opening and closing the umbrella, and cannot achieve both automatic opening and automatic closing. This is because when opening and closing the umbrella, the lower nest of the existing straight-bone type umbrella rib structure has a longer moving stroke than the upper nest, resulting in a longer travel of the pull line, which makes it impossible to set the umbrella handle button device for automatic opening, and the predetermined purpose of automatic opening and closing the umbrella cannot be achieved. Summary of the invention

[0003] The object of the present invention is to provide a straight rib type automatic opening and closing umbrella rib structure to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A straight-bone type automatic opening and closing umbrella rib structure, comprising a middle rod, a lower nest, a double-layer integrated upper nest composed of an upper nest and a lower nest, an umbrella rib bracket composed of a plurality of umbrella frames, a pulley assembly, and an umbrella handle control assembly for controlling the opening and closing of the umbrella; the umbrella frame comprises a supporting rib, an umbrella closing tension spring, a foldable short rib composed of an inner short rib and an outer short rib, and a long rib; the pulley assembly comprises a pulley, a pulley seat, and a pull line;

[0006] The inner end of the long bone is hinged to the upper nest, the inner end of the inner short bone is hinged to the lower nest, the inner end of the branch bone is hinged to the lower nest, and the outer end is hinged to the inner lower side of the middle section of the short bone, the inner end of the umbrella retracting tension spring is connected to the inner side of the outer end of the branch bone, and the outer end is connected to the lower side of the middle section of the inner short bone, the inner end of the outer short bone is hinged to the outer end of the inner short bone, and the outer end is hinged to the lower side of the middle section of the long bone;

[0007] An opening is provided on one side of the upper end of the middle rod, a side convex cavity is provided on one side of the double-layer integrated upper nest, and the pulley seat is fixedly installed on the upper end of the middle rod; the pulley shaft is connected to the pulley seat, and one side extends out from the opening on the upper end of the middle rod and extends into the side convex cavity; the outer end of the pull wire is fixedly connected to the lower nest, and the inner end passes through the opening on the lower side of the side convex cavity, bypasses the pulley, and is linked to the umbrella handle control component through the internal cavity of the pulley seat and the internal cavity of the middle rod;

[0008] When the umbrella is opened, the inner end of the pull line moves downward and the outer end moves upward, driving the lower nest to move upward, and the lower nest drives the inner end of the support bone to move upward, and the outer end of the support bone pushes the inner side of the middle section of the inner short bone, and the outer end of the inner short bone moves outward and upward with the hinge point between the inner end of the inner short bone and the lower nest as the axis, driving the outer short bone and the long bone to move in tandem, and the umbrella retracting spring is stretched and becomes longer, and the outer end of the long bone moves outward and upward with the hinge point between the inner end of the long bone and the upper nest as the axis, until the inner end of the pull line is positioned with the umbrella handle control assembly, and the umbrella is in an unfolded state;

[0009] When folding the umbrella, the umbrella handle control assembly is controlled to separate it from the inner end of the pull line. Under the action of the contraction elastic force of the umbrella folding spring, the outer end of the outer short bone is folded toward the inner end of the inner short bone, the inner end of the inner short bone drives the lower nest to move downward, and the outer end of the long bone moves inward and downward until the inner end of the pull line moves up to the positioning point, and the umbrella is in a folded state.

[0010] Here, the lower nest drives the support bone, pulls the umbrella-folding spring, and links the foldable short bone composed of the inner short bone and the outer short bone, so as to effectively shorten the moving stroke of the lower nest when the umbrella is opened and closed, so as to facilitate the setting of the umbrella handle button device, laying a solid foundation for realizing automatic opening and closing of the umbrella. At the same time, the shortening of the lower nest stroke also shortens the time for folding and opening the umbrella.

[0011] It should be noted that the pull wire here is connected to the lower nest, which drives the lower nest to slide up and down along the middle rod through the handle button device to control the opening and closing of the umbrella; the umbrella handle control component can adopt the method of cooperating with the umbrella handle button device and the corresponding structure to realize automatic opening and closing of the umbrella and positioning and separation of the pull wire. The corresponding structure can be realized, but it is not described here because it does not belong to the scope of this technical solution and the protection scope of the application.

[0012] To facilitate installation and mass production of parts, preferably, the middle section fixing sleeve of the long bone is provided with a middle joint with a lower hinge point, and the inner end fixing sleeve is provided with an inner joint with an inner hinge point; the short bone is composed of an inner short bone and an outer short bone, and the inner short bone is connected to the outer short bone in a hinged manner to form a foldable structure; the outer end of the outer short bone is hinged to the lower hinge point of the middle joint, and the inner joint is hinged to the upper nest through the inner hinge point.

[0013] In order to stabilize the hinge between the outer short bone and the inner short bone, preferably, a limit plate extending inward is provided on the outer side of the inner end of the outer short bone. When the umbrella is folded until the foldable short bones composed of the inner short bone and the outer short bone are aligned, the limit plate limits the inner short bone and the outer short bone from rotating outward around the hinge point to improve the stability of the umbrella rib bracket.

[0014] In order to better fix the pulley seat on the upper end of the middle rod, preferably, the upper end of the middle rod is provided with a pin hole that penetrates through it, and the pulley seat is matched and fixed to the upper end of the middle rod by the pin.

[0015] In order to make the umbrella more light and durable, preferably, the long bones are fibrous long bones, but not limited to fibrous long bones.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: In the straight-bone type automatic opening and closing umbrella bone structure of the present invention, through the settings of the upper nest, the structure of the umbrella frame, and the pulley assembly, when the umbrella is in use, the lower nest drives the support bone, pulls the umbrella closing spring, and interlocks the foldable short bone composed of an inner short bone and an outer short bone, achieving the purpose of effectively shortening the moving stroke of the lower nest when the umbrella is opened and closed, so as to facilitate the setting of the umbrella handle button device, laying a solid foundation for realizing the automatic opening and closing of the umbrella, and having the characteristics of stable structure, convenient opening and closing, rapid opening and closing, safety and convenience.
