Abstract
Description
Technical Field
[0001] The utility model relates to a component of an umbrella for daily use, in particular to a structural improvement of a multi-fold umbrella rib, which is applicable to manual or automatic multi-fold umbrellas. Background Art
[0002] At present, multi-fold umbrellas on the market are widely used because they can be folded and are convenient to carry. A multi-fold umbrella consists of multiple sets of radial umbrella frame units that form the skeleton supporting the umbrella surface. The typical structure of the umbrella frame unit of the most common three-fold umbrella is as Figure 1 shown, including: a first umbrella rib 91, a second umbrella rib 92, and a third umbrella rib 93 that are sequentially hinged from the inside to the outside, a short rib 94 whose outer end is hinged to the middle of the first umbrella rib 91, a short pull wire 95 connecting the short rib 94 and the second umbrella rib 92, and a long pull wire 96 connecting the first umbrella rib 91 and the third umbrella rib 93. By pushing and pulling the lower nest to change the angle between the first umbrella rib 91 and the short rib 94 and the pulling of the long and short pull wires, the extension and folding of the umbrella frame unit can be realized.
[0003] However, the length of the existing three-fold umbrella after folding is still relatively long and cannot be carried around in a small bag. If a shorter folding length is to be achieved, one way is to only make more folds, but this also correspondingly increases more umbrella rib components and the labor required for assembly, resulting in an increase in cost; the other way is to use shorter umbrella ribs, but this also correspondingly causes the problem that the shielding length of the umbrella surface after opening the umbrella is shorter. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a telescopic umbrella rib with a shorter length after folding but a longer length after extension.
[0005] The technical solution adopted by the utility model to solve the above technical problem is to design and manufacture a telescopic umbrella rib, including: a first umbrella rib and a second umbrella rib that are sequentially connected from the inside to the outside, a short rib whose outer end is hinged to the middle of the first umbrella rib, and a short pull wire whose two ends are respectively connected to the short rib and the second umbrella rib; the inner end of the short rib is connected to the movable nest of the umbrella;
[0006] It further includes: a movable long rib that is slidably connected to the first umbrella rib along its length direction, and a limiting rib whose two ends are respectively connected to the movable long rib and the short rib; the connection part of the limiting rib and the movable long rib is located inside the inner end part of the first umbrella rib, and the inner end part of the movable long rib is connected to the upper nest of the umbrella;
[0007] When opening the umbrella, the angle between the movable long rib and the short rib becomes smaller, and the limiting rib pushes the outer side of the short rib to move outward, driving the first umbrella rib to slide outward and extend; when closing the umbrella, the angle between the movable long rib and the short rib becomes larger, and the limiting rib pulls the outer side of the short rib to retract inward, driving the first umbrella rib to contract inward and fold.
[0008] Both ends of the limiting bone are respectively connected to the inner side of the movable long bone and the outer side of the short bone.
[0009] The first rib is made of grooved bone, and the movable long bone is sleeved in the groove of the first rib.
[0010] A connecting piece is fixedly arranged at the outer end of the movable long bone, and the connecting piece extends towards the position of the umbrella cloth and is provided with a sewing hole for sewing the umbrella cloth.
[0011] The connecting piece is provided with a pulling wire hole on the side facing the short pulling wire for the short pulling wire to pass through.
[0012] Compared with the prior art, the telescopic rib of the present utility model is provided with a movable long bone that can be telescoped along the length direction of the first rib and a limiting bone connecting the movable long bone and the short bone. When the umbrella is opened, the first rib and the movable long bone that support the umbrella surface extend and become longer, and when the umbrella is closed, the first rib and the movable long bone are folded and shortened, so that the rib has a longer shielding length when the umbrella is opened and a shorter folding length when the umbrella is closed, which is convenient for putting the umbrella into a small bag, and is very convenient and practical to use.

[0017] The following is a further detailed description with reference to the preferred embodiment shown in the drawings.
[0018] The telescopic rib of the present utility model is applicable to multi-fold umbrellas with two or more folds. For the convenience of description, here it is defined that the direction close to the umbrella nest body is the inner side, and the direction away from the umbrella nest body is the outer side.
[0019] Hereinafter, the most common three-fold umbrella will be taken as an example for illustration. As Figure 2 and Figure 3 shown, the telescopic rib of the present utility model includes: a movable long bone 6, a first rib 1, a second rib 2, and a third rib 3 that are sequentially connected from the inside to the outside, a short bone 4, a short pulling wire 5, a limiting bone 7, and a long pulling wire 8.
[0020] Among them, the movable long bone 6 is slidably connected to the first rib 1 along the length direction of the first rib 1, that is, the movable long bone 6 can slide in and out relative to the first rib 1. The inner side of the second rib 2 is hinged to the outer end of the first rib 1, and the inner side of the third rib 3 is hinged to the outer end of the second rib 2. The outer end of the short bone 4 is hinged to the inner side of the first rib 1. Both ends of the limiting bone 7 are respectively connected to the inner side of the movable long bone 6 and the outer side of the short bone 4. Both ends of the short pull wire 5 are respectively connected to the outer side of the short bone 4 and the inner end of the second rib 2. Both ends of the long pull wire 8 are respectively connected to the outer side of the first rib 1 and the inner end of the third rib 3.
[0021] The connection part of the limiting bone 7 and the movable long bone 6 is located inside the inner end part of the first rib 1. The inner end part of the movable long bone 6 is connected to the upper nest fixed at the top of the umbrella middle rod (the umbrella middle rod and the upper nest are not shown in the figure). The inner end of the short bone 4 is connected to the movable nest of the umbrella (that is, the nest body that can slide up and down along the umbrella middle rod).
[0022] When opening the umbrella, as Figure 3 shown, the lower nest of the umbrella will move upward. The included angle between the movable long bone 6 and the short bone 4 becomes smaller. The limiting bone 7 pushes the outer side of the short bone 4 to move outward, thereby driving the first rib 1 to slide and extend outward along the movable long bone 6. Thus, the length that the movable long bone 6 and the first rib 1 can support the umbrella cloth when opening the umbrella can be greatly extended, and the shielding length when opening the umbrella can be increased.
[0023] When closing the umbrella, as Figure 2 shown, the lower nest of the umbrella will move downward. The included angle between the movable long bone 6 and the short bone 4 becomes larger. The limiting bone 7 pulls the outer side of the short bone 4 to move inward, driving the first rib 1 to contract and fold inward along the movable long bone 6. Thus, the length of the movable long bone 6 and the first rib 1 when closing the umbrella will be greatly shortened. Therefore, the length of the umbrella ribs when closing the umbrella can be reduced, which is convenient to be put into a small bag and carried around.
[0024] In this embodiment, as Figure 4 shown, the first rib 1 is made of grooved bone, and the movable long bone 6 is sleeved in the groove of the first rib 1. A connecting piece 61 is fixedly arranged at the outer end of the movable long bone 6. The bottom of the connecting piece 61 extends towards the side and then towards the umbrella cloth to form an L-shaped lug 64. A sewing hole 62 for the umbrella cloth sewing thread is opened at the end of the lug 64. By sewing the thread in the sewing hole 62, the connecting piece 61 and the umbrella cloth can be sewn together. In this way, when closing the umbrella, the umbrella cloth of the lengthened part can be folded inward to prevent the redundant umbrella cloth from piling up outside and looking messy after closing the umbrella. In addition, the outer end part of the movable long bone 6 can be positioned to prevent it from falling out of the first rib 1 downward. The connecting piece 61 is also provided with a wire hole 63 for the short pull wire 5 to pass through on the side facing the short pull wire 5, which has a limiting effect on the short pull wire 5, so as to prevent the short pull wire 5 from being deformed due to excessive force during the process of opening and closing the umbrella.
[0025] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
