Description

Sliding rod umbrella cloth support bone

technical field

The invention relates to the field of umbrella cloth support bones, in particular to an umbrella cloth support bone capable of reducing the volume of the umbrella after folding while ensuring the umbrella can be easily folded.

Background technique

The three-fold and four-fold umbrellas sold on the market at least include an umbrella handle rod, an umbrella rib and an umbrella cloth, the umbrella cloth is sewn on the umbrella rib, and the umbrella rib is mounted on the top of the umbrella handle rod; the umbrella rib It includes a plurality of umbrella cloth support bones, if the umbrella handle rod and each umbrella cloth support bone are folded.

Compared with the existing umbrellas that cannot be folded, the three-fold umbrella has the advantages of small size, convenient carrying and storage, etc.; and the four-fold umbrella, compared with the three-fold umbrella, further reduces the volume of the entire umbrella, thereby further improving the carrying and carrying capacity. It is convenient to carry when going out, but any support bone in the umbrella rib of the four-fold umbrella is formed by four rods hinged to each other, and adding a rod increases the sewing difficulty between the umbrella cloth and the support bone, thereby increasing the processing cost. The three-fold umbrella has the advantage of convenient processing, but the folded volume of the three-fold umbrella cannot achieve the effect of the four-fold umbrella, which directly affects the convenience of its use.

In addition, any supporting rib connection part of the existing umbrella rib is connected by a joint structure. The existing structure cannot increase the length when the umbrella rib is opened, but it occupies the space length when the umbrella rib is folded, which affects the storage of the entire umbrella. The length of the three-fold umbrella required in this case can achieve the storage effect of the four-fold umbrella.

Therefore, how to combine the advantages of convenient processing and smaller size of the three-fold umbrella is the reason for this case.

The hinge point of the fifth bone rod and the fourth bone rod is the first hinge point, the hinge point of the sixth bone rod and the seventh bone rod is the second hinge point, and both ends of the sixth bone rod pass through The connection of the first and second hinge points forms a diagonal line in the above-mentioned quadrilateral structure, so as to control the folding and extension of the second and third bone rods.

Further preferably: the fourth bone rod includes a first straight line segment and a second straight line segment that are connected by bending, the first straight line segment is inclined toward the first bone rod and its lower end is connected to the first bone rod. The second straight line segment is placed under the first bone rod, the first bone rod and the second straight line segment of the fourth bone rod cooperate to form a scissors-type mechanism, and the fifth bone rod and the fourth bone rod The first straight segments of the rods cooperate to form adjacent two-side structures in the quadrilateral.

Further preferred: the second hinge point is located below the second bone rod.

Further preferably: the second bone rod is provided with an adjacent end hinge hole and a middle hinge hole near one end of the first bone rod, wherein;

The hinge hole at the end is opened at the end of the second bone rod close to the first bone rod, and is used for hinged connection with the first bone rod;

The middle hinge hole is opened on the protruding portion of the second bone rod toward the extension, and is arranged near the hinge hole at the end, and is used for hinged connection with the fifth bone rod;

The second bone rod is located at a section between the middle hinge hole and the end hinge hole, and cooperates with the first bone rod to form two adjacent sides in the quadrilateral structure.

Further preferably: the third bone rod is provided with an end hinge hole and a middle hinge hole near one end of the second bone rod, wherein:

The end hinge hole is opened at the end of the third bone rod close to the second bone rod, and is used for hinged connection with the second bone rod;

The middle hinge hole is opened near the end hinge hole, and is used for hinged connection with the seventh bone rod.

Further preferably: a sliding positioning member is sleeved in the middle of the seventh bone rod, and the sliding positioning member is fixed in the middle of the second bone rod to form a structure that restricts the sliding of the seventh bone rod, thereby controlling the third bone rod fold and stretch.

Compared with the prior art, the present invention has the following advantages:

In the present invention, the first bone rod, the second bone rod, the fourth bone rod, and the fifth bone rod cooperate to form a quadrilateral structure, and a diagonal structure of the sixth bone rod is added to the quadrilateral structure. When the quadrilateral structure is compressed, the sixth bone rod expands, thereby pushing the linked seventh bone rod and the third bone rod to achieve the expansion of the entire umbrella support bone; on the contrary, when the quadrilateral structure is expanded, the sixth bone rod is expanded. The bone rod is folded, so that the sixth and third bone rods are driven to realize the folding of the entire umbrella support bone, so that the umbrella rib with the umbrella cloth support bone can ensure the same effective use area of the umbrella surface. The length of the storage is effectively shortened;

Therefore, the cloth support bone of the present invention can be the longest when opened, but can be the shortest when folded and retracted, so that the umbrella can be stored and used well.
