Description

Combined umbrella frame

technical field

The utility model relates to an umbrella, in particular to a combined umbrella frame proposed for the umbrella frame in the umbrella. It utilizes this design and makes it have the function of easy assembly, so it becomes a quite practical and progressive new design, which is suitable for wide popularization and application in the industry.

Background technique

The current umbrella design for sunshade and rain shelter mainly includes a collapsible umbrella frame group and an umbrella cloth covered on the top surface of the umbrella frame. As shown in Figure 5, the umbrella frame includes a main umbrella pole 40 and A set of ribs 50 set on the main umbrella pole 40, the lower end of the main umbrella pole 40 is provided with a handle, and a movable buckle is provided at the predetermined position of the lower section, and the umbrella framework 50 includes an upper ring nest 51. The middle ring nest 52, the lower ring nest 53 and the same number of first ribs 54, second ribs 55 and third ribs 56, wherein the upper ring nest 51 is fixed on the upper end of the main umbrella pole to provide the first Umbrella ribs 54 are movably arranged on the outer ring part of the ring, and are fixed with iron wires 57. The middle ring nest 52 is movably sleeved on the upper umbrella pole 51 relative to the lower part of the upper ring nest 51. And one end of these second ribs 55 can be arranged on the outer ring part of the middle ring nest 52, and the iron wire 57 is passed through it to fix it, and the other end is movably connected to the corresponding first ribs 54 by rivets. In the middle section, the lower ring nest 53 is movably sleeved on the main umbrella pole 40 below the middle ring nest 52, and a spring 58 is respectively set between the upper ring nest 51, the middle ring nest 52 and the lower ring nest 53, And one end of these third ribs 56 can be arranged on the outer ring part of the middle ring nest 52, and the iron wire 57 is passed through it to fix it, and the other end is movably connected to the corresponding second ribs 55 by rivets. In the middle section, the umbrella cloth can be covered and set on the first rib 54 of the rib set 50 to form an umbrella that can be expanded or collapsed.

Although the above-mentioned umbrella provides a device that can be applied to purposes such as sunshade and rain shelter with its structural design, and the umbrella can be folded and unfolded for ease of use, however, the umbrella skeleton design of the umbrella still exists. There are many shortcomings to be improved, among them:

1. The assembly is very inconvenient: because the first rib, the second rib, and the third rib of the umbrella frame are respectively arranged in the outer ring of the upper ring nest, the middle ring nest, and the lower ring nest, and are passed through by iron wires It is tied and fixed, and the joints between the first, second and third umbrella ribs are assembled with rivets and tools, which is very inconvenient in assembly.

2. The safety of use is poor: the rib rings of the umbrella frame are arranged in the upper, middle and lower ring nests and are fixed by iron wires passing through them, and the two ends of the iron wires are fixed by spiral twisting. The twisted ends of the iron wires are exposed, causing users to be easily cut by the sharp ends of the iron wires when using the umbrella, so there is a problem of poor safety in use.

3. Materials such as iron wires must be electroplated, which will cause environmental pollution: As mentioned above, each umbrella rib of the umbrella frame needs to be fixed around the ring nest by iron wires. Since the iron wires will rust, the iron wires It must go through an anti-rust layer of electroplating first, and the process of electroplating will pollute the environment and be poisonous to the human body due to the use of toxic substances.

4. The ribs cannot be replaced by themselves after the ribs are broken: During the use of the umbrella, sometimes due to excessive wind or careless operation, a certain rib in the umbrella frame will break. Bone replacement requires special tools and specific rivets, which is not something ordinary people can do by themselves. As a result, people often discard most of the umbrellas that are still in good condition, which is a waste of resources.

In order to solve the defects of the existing umbrella frame, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time. And the umbrella frame that can have all-round adjustment function when in use has just become the goal that current industry needs to improve very much.

In view of the above-mentioned defects of the existing umbrella frame, the designer, based on years of rich practical experience and professional knowledge in the design and manufacture of such products, and with the application of academic theory, actively researched and innovated, in order to create a combination of new structures The umbrella frame can improve the general existing umbrella frame and make it more practical.
