Technical Field

The invention relates to the field of frameworks of umbrellas, in particular to a multi-fold umbrella framework capable of shortening the folding length, which can ensure that the umbrella is conveniently folded and can also reduce the volume of the folded umbrella.

Background

The connecting part of any supporting bone in the umbrella ribs of the existing multi-folding umbrella is formed by connecting a joint structure, but the length of the existing joint structure cannot be increased when the umbrella ribs are opened, but the existing joint structure occupies the space length when the umbrella ribs are folded, and the length of the whole umbrella in storage is influenced. That is to say, in the prior art, the folded length of the two-fold umbrella is greater than that of the three-fold umbrella, and the folded length of the three-fold umbrella is greater than that of the four-fold umbrella, so as to analogize.

In order to enable the folded length of the three-fold umbrella to be equal to the folded length of the four-fold umbrella, chinese patent document CN 108887821A discloses a folding umbrella cloth supporting rib, which comprises a first rib rod, a second rib rod and a third rib rod, wherein the first rib rod, the second rib rod and the third rib rod are sequentially hinged end to end through a hinge element to form a link mechanism which can be rotatably folded by taking a hinge point as a circle center; the first bone rod and the second bone rod are hinged in sequence, the fourth bone rod comprises an upper driven bone rod and a lower movable bone rod, the upper driven bone rod and the lower movable bone rod are sequentially hinged in sequence from head to tail, the free end of the upper driven bone rod is hinged between the first bone rod and the second bone rod, and a single-axis point double-parallel scissors type structure is formed. The lower movable bone rod is hinged to the middle of the first bone rod and is formed by matching with the free end of the first bone rod. The invention develops and utilizes the single-axis point double-parallel scissor type transmission on the umbrella rib structure, effectively shortens the length of the first and second rib rods at the hinged position in the folded state, and further effectively shortens the length of the umbrella ribs with the umbrella cloth supporting ribs after being folded on the premise of ensuring the same effective umbrella surface using area.

Although the structure can only have the length of a four-fold umbrella after the three-fold umbrella is folded, the parallelogram structure adopted by the umbrella ribs has the problems that the umbrella ribs are unstable and easy to swing when the umbrella is folded, and the anti-turnover capacity of the umbrella tail ribs is poor.

Disclosure of Invention

The invention aims to solve the problems and provides a multi-fold umbrella rib which has stable structure, does not swing, has good anti-fracture and anti-turnover capability of an umbrella tail and can shorten the folding length when the umbrella is folded.

The technical scheme of the invention is realized as follows: a multi-fold umbrella rib capable of shortening the folding length comprises a tail rib and at least one umbrella rib, wherein the multi-fold umbrella rib is hinged with the upper end of the tail rib through a first hinge; the invention also comprises movable umbrella ribs, wherein the lower ends of the movable umbrella ribs are sleeved on the tailbone and are in sliding connection with the tailbone, the positions, close to the upper ends, of the movable umbrella ribs are hinged with the positions, close to the first hinge parts, of the first umbrella ribs through second hinge parts, the first umbrella ribs and the movable umbrella ribs form a scissor fork structure, meanwhile, the tailbone, the first umbrella ribs and the movable umbrella ribs form a triangular structure when the umbrella is folded, and a linear structure is formed when the umbrella is unfolded.

As an improvement to the invention, the upper end of the movable umbrella rib is hinged with the elastic wire.

As an improvement to the invention, the movable umbrella rib comprises a first connecting piece and a second connecting piece, the first connecting piece and the second connecting piece are arranged in parallel, the first umbrella rib is clamped between the first connecting piece and the second connecting piece, and the lower ends of the first connecting piece and the second connecting piece are sleeved on the tailbone through a lantern ring.

As an improvement of the invention, the movable umbrella rib comprises a first connecting piece, the lower end of the first connecting piece is sleeved on the tailbone through a lantern ring, and after the umbrella is folded, the first connecting piece and the first umbrella rib are completely overlapped.

As an improvement of the invention, the lower end of the coccyx is provided with a coccyx head.

As an improvement of the invention, a connecting piece is arranged at the upper end of the first umbrella rib.

According to the invention, as the movable umbrella ribs are additionally arranged, the lower ends of the movable umbrella ribs are sleeved on the tailbone and are in sliding connection with the tailbone, the positions, close to the upper ends, of the movable umbrella ribs are hinged with the positions, close to the first hinge parts, of the first umbrella ribs through the second hinge parts, so that the first umbrella ribs and the movable umbrella ribs form a scissors fork structure, meanwhile, the tailbone, the first umbrella ribs and the movable umbrella ribs form a triangular structure when the umbrella is folded, and a linear structure is formed when the umbrella is unfolded. Therefore, when the umbrella is folded, the umbrella ribs can be more stable when the umbrella is folded by using the stability of the triangle due to the existence of the triangle structure; because the structure that the lower end of the movable umbrella rib is sleeved on the tail bone is adopted, the movable umbrella rib can effectively support the tail bone, and the wind-proof capability of the tail bone can be enhanced.
