The present invention relates to a lightweight umbrella breakage prevention device. More specifically, the use of lightweight umbrellas and the provision of reinforcing elements between the mother's or underboards prevent the damage of the umbrellas when the umbrellas are folded or unfolded or when they are impacted from the outside. It relates to a damage prevention device.

In the umbrella that is used in general, the umbrella meat is joined to the upper cap fixed to the upper part of the umbrella stand, and the eight mother flesh which stretches the umbrella cloth on the outer side, and the one end to the lift cap that is freely fitted to the umbrella stand and the other end are joined. It is connected to the middle part of each mother's body, and it has eight bases which support each mother's body below and inside.

In addition, both the mother and the underarm of an umbrella meat are metal. In addition, the umbrella meat and the meat of the umbrella to be molded or molded employ various materials in order to improve the weight and aesthetics of the umbrella. For example, it is used as a plastic material. However, umbrellas using this plastic material are not excellent in rigidity and toughness due to the characteristics of the material, and do not satisfy the weight and aesthetics.

When the umbrella is unfolded, the base is fixed to raise the lifting cap along the umbrella stand and stops the lowering of the lifting cap by the upper spring, and the mother meat is supported by the base from the bottom to maintain the unfolded state. However, because the underlay is fixed when external force is applied from the distal end to the umbrella relative to the undercarriage, the underlay acts to press the undercarriage outward through the connecting portion. And the mother flesh is bent downward by the tension of the umbrella cloth attached to the outer surface. Therefore, the impact force, which is an external force applied from the outside of the mother flesh, concentrates on the connection portion of the mother flesh.

Therefore, the twisting force received by the blown or thrown by the wind while the umbrella is folded or unfolded, or the impact force when the impact is caused by the impact on the bottom surface or the wood or building, is concentrated on the connection between the killing and the support Because of this, the breakage of bending or bending, bending, bending, twisting, etc. occurs due to the impact of the outside of the umbrella at the point of the connecting portion or the outer portion of the tip body side of each piece of the short connecting port.

In addition, even if the plastic or metal material can be reduced in weight as a material using a lightweight umbrella meat, when the connection part of the mother meat is extended to the umbrella or is impacted from the outside of the umbrella, the material is broken. Due to its prone nature, it causes the break of the umbrella.

Therefore, an object of the present invention is to provide a lightweight umbrella break preventing device that prevents breakage of the mother and / or buttocks and its connecting portion which will occur when the umbrella in the open or folded state is impacted.

In the present invention, in order to achieve the above object, in the apparatus for preventing breakage of umbrella meat, the connection part between the first and second mother meat 10, 10a for connecting and supporting the umbrella cloth 5 through the yarn 6, The reinforcing member 20 for reinforcing the first and second mother meat 10, 10a is sandwiched between densely filled its inner space in the U-shaped groove, and the reinforcing member 20 is made of glass fiber. It is made of, and is configured to be folded or bent by fixing the bending caulking inwardly toward both sides of the mother meat (10, 10a) inside the reinforcing member 20, the mother meat (10, 10a) is inserted into the arrangement .

In addition, the device for preventing breakage of the umbrella meat according to the present invention is a connection protrusion 12 extending from the mother meat 10 of the rod-shaped body 20a installed therein at the connection portion with the support meat 40 of the mother meat 10. And a connecting grommet hole 38 extending from the base 40.

In addition, the umbrella cloth 5 of the present invention is preferably made of ultra-fine yarn of 100% polyester having a thin thickness and excellent waterproofness and water repellency.

According to the present invention, the reinforcing member 20 is sandwiched between the first and second mother meat 10, 10 a in the connecting portion with the support meat of the mother meat in a state of densely filling the space in the U-shaped groove. Since the rod body 20a of the mother meat 10 and the base meat 40 is formed, and the reinforcement member 20 and the rod body 20a for reinforcement are rich in absorbency of impact force in relation to a material, Even if excessive impact force concentrates at the connection point with (10, 10a) and / or the receiving body 40, the impact force is absorbed and relaxed sufficiently.
