Umbrellas with frames according to this utility model not only have durability at the joints, but also have a good appearance. Neither the umbrella cover nor the hands will be scratched. Umbrellas have a beautiful appearance and have a long service life. This utility model is applicable to a variety of umbrellas made from fiber ribs.

Description

The present utility model relates to an umbrella element, in particular to a hinge structure for fiber ribs.

Due to their high strength and suitable elasticity, carbon fibers and fiberglass are used more and more for umbrella frames. Existing umbrellas that use frames made of fibers often have a metal insert directly on the hinged sections of the frame to provide sufficient wear resistance on the hinged sections. An example is provided in a Chinese utility model with patent number 99208967.0. Despite the fact that such hinges of the frame are quite durable, however, they have an ugly appearance due to the fact that the colors of the metal and fibers are too different. In addition, the sharp edges of the metal inserts will cut through the fiber frames, which reduces the life of the umbrellas.

The objective of this utility model is to create an umbrella frame that is durable and has a good appearance.

The objective of this utility model can be implemented in the following technical project: development of an umbrella frame that contains fiber ribs pivotally connected to each other to form an umbrella frame. Such a frame is characterized in that the above fiber umbrella frame has unique hinges, such as: the outer surface of the hinge base is covered with a metal reinforcing layer, which in turn is wrapped in a plastic layer. Layered structure of the above hinges

The ribs of the umbrella frame are applicable to folding umbrellas that have frames with three, four, five and even six compartments.

When used in a three-section folding umbrella, the aforementioned fiber frame of the umbrella contains main ribs and short supporting ribs that are pivotally attached to the upper and lower connectors, respectively, end ribs on the outside and connecting (hinged, rising) ribs that connect the above main ribs and end ribs.

The above hinges comprise: a first hinge on the inside of the short support rib for swiveling with the lower connector, a second hinge on the outside of the short support rib for swiveling with the main rib in its middle, a third hinge on the inside of the main rib for swiveling with the upper connector , the fourth hinge in the center of the main rib for swivel with a short support rib, the fifth hinge on the outside of the main rib for swivel with the ridge, the sixth hinge on the inner side of the connecting ribs for swiveling with the main rib, and the seventh hinge on the outer surface of the connecting ribs for swiveling with the end rib.

A blind groove is made in the metal reinforcing layer to prevent the plastic layer from slipping out of the metal reinforcing layer.

Compared with existing technology, a real utility model of an umbrella fiber frame has the following features: since the hinges of the umbrella fiber frame are first

wrapped in a metal layer, and then covered with a plastic layer, the sharp edges of the metal layer are wrapped in a plastic layer that closely interacts with the edges of the fiber frame, protecting them from damage by such sharp metal edges. In addition, it is quite simple that the color of the plastic layer is the same as the color of the fiber ribs. The fiber frame of the umbrella according to this utility model has a good appearance and has a long service life.

The essence of the utility model is illustrated in the drawings, where:

figure 1 shows a structural diagram of the ribs of the frame of the umbrella in the present utility model, when it is used for a three-section folding umbrella;

figure 2 shows a diagram of the above main rib 32;

figure 3 shows a diagram of the above short support ribs 31;

figure 4 shows a diagram of the above connecting ribs 33;

figure 5 shows a cross section aa from figure 2;

figure 6 shows a cross section bb in figure 2;

in Fig.7 shows a cross section CC of Fig.3.

The frame of a three-section folding umbrella is shown as an example to explain the present utility model in conjunction with the accompanying drawings.

As shown in FIG. 1, the umbrella frame in the present utility model comprises fiber ribs 3 that are articulated together to form the umbrella frame and tension cables. The above fiber ribs 3 umbrellas

contain main ribs 32 and short support ribs 31, which are pivotally connected to the upper and lower connectors, respectively, end ribs 34 from the outside, connecting ribs 33, which connect the main ribs 32 and end ribs 34 to each other through hinges. The hinges 2 of the aforementioned fiber ribs 3 contain: a first hinge 11 on the inner side of the short support rib 31 for hinging with the lower connector, a second hinge 12 on the outside of the short supporting rib 31 for hinging with the main rib 32 in its middle part, the third hinge 13 on the inner side of the main rib 32 for articulation with the upper connector, the fourth hinge 14 in the middle of the main rib 32 for articulation with a short support rib 31, the fifth hinge 15 on the outside of the main about the ribs 32 for swiveling with a connecting rib 33, the sixth hinge 16 on the inner side of the connecting ribs 33 for swiveling with the main rib 32, and the seventh hinge 17 on the inner side of the connecting ribs 33 for swiveling with the end rib 34.

As shown in FIGS. 5 and 6, all of the above hinges 2 have the following features: the outer surface of the hinge base 20 in the fiber ridge 3 of the umbrella is covered with a metal reinforcing layer 21, which in turn is covered with a plastic layer 22. The above metal reinforcing layer 21 may either be made of a curved strip of metal, or be an integrated housing. The processing progress is as follows: first, the overlay of the metal layer 21,

which has the same shape as the plastic layer 22, which should be poured, but slightly smaller in size, on the hinge base 20 in the fiber rib 3, and the injection of the plastic layer 22 on the metal layer 21.

As shown in figures 2 to 4, to prevent slipping of the reinforcing metal layer 21 from the plastic layer 22 in the metal reinforcing layer 21, a blind groove 23 is made to prevent sliding. When the plastic layer 22 is poured in, the plastic will enter the blind groove 23 to adhere the metal reinforcing layer 21 to the fiber rib 3 (as shown in FIG. 5), thereby greatly improving its integrity.

As shown in figures 2 to 4, each of the aforementioned first hinge 11, third hinge 13, and seventh hinge 17 has a hole at one end for connecting to the fiber rib 3, and has another hole at the other end for swiveling. The metal reinforcing layer 21 of the second hinge 12 comprises a tongue 27, the end of which extends obliquely upward, and a hinge hole 121 (as shown in FIG. 7) with a U-shaped protrusion 25, which extends upward from the center and has holes for the hinge. Both ends of the metal reinforcing layer 21 in the fourth hinge 14 have through holes for the main rib 32, and the U-shaped protrusion 25 is located in the center of the metal reinforcing layer 21 with holes 141 on its two side walls for swiveling (as shown in FIG. 5 ) Metal reinforcing layer 21 in the fifth joint 15

contains two tabs 26, extending upward, with a hole 151 for swivel (as shown in Fig.6). The metal reinforcing layer 21 in the sixth hinge 16 contains two U-shaped protrusions 25, which extend upward in its center and at the end, with holes respectively in both of their side walls for articulation.

The preferred embodiment described above is only an example of a three-section folding umbrella, however, the present utility model can be applied to the frames of folding umbrellas folding four, five, six or another number of times.
