Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a type of umbilical bone destruction prevention device, in particular, one auxiliary bone is added between a receiving bone and a main bone, and both ends of the auxiliary bone are respectively rotated to a connecting portion between the outer end of the receiving bone and the main bone. The present invention relates to an umbrella bone destruction prevention device, which is capable of preventing the destruction of a rib and an articulated portion by extension of an auxiliary bone when the umbrella is connected to oneself and rolls up in a headwind.

[0002]

[Prior art]

 Umbrellas are a daily necessity to block rain and sunlight. When an umbrella is used, if the wind blows into the inside of the umbrella, the position of the connecting portion 11 between the rib 1 and the receiving bone 2 of the umbrella is likely to bend upward and break. After such a situation, the umbrella could not be used normally. This is a problem that most umbrellas have today.

[0003]

[Problems to be solved by the invention]

 The present invention provides a kind of umbrella bone destruction prevention device, so that when the umbrella is rolled up by the headwind, the ribs can be smoothly moved upward without causing a bending phenomenon, and thereby the umbrella bone or the umbrella bone can be prevented. It is an object to prevent damage to the connecting portion.

[0004]

[Means for Solving the Problems]

 According to the invention of claim 1, an upper wheel 5 is provided on the upper portion of the inner bar 4, a lower wheel 6 is fitted to the inner bar 4 so as to be slidable up and down, and the inner end of the rib 1 is rotatably connected to the upper wheel 5. An umbrella in which the inner end of the receiving bone 2 is rotatably connected to the lower wheel 6, and one end of the auxiliary bone 3 is rotatably connected to the outer end of the receiving bone 2, and the other end is the middle step of the main rib 1. The auxiliary bone 3 connected to the connecting portion 11 of the rib 1 is stretched when the rib 1 is rotatably connected to the connecting portion 11 fixed at the position and receives the reverse wind blown from the inside of the umbrella to blow up the rib 1 integrally with the raw cloth. The ribs 1 are moved up to hold the ribs 1 in a straight line to prevent destruction.

According to the invention of claim 2, one end of the auxiliary bone 3 is connected to the outer end of the receiving bone 2, and the other end of the auxiliary bone 3 is located at a more central position than the position of the rib 1 corresponding to the outer end of the receiving bone 2. The umbrella bone destruction prevention device according to claim 1, wherein the device is provided at a close position.

The invention according to claim 3 is characterized in that one end of the auxiliary bone 3 is connected to the outer end of the receiving bone 2 and the other end is further extended outward and connected to the rib 1. An apparatus for preventing umbrella bone destruction according to claim 1 is provided.

[0007]

[Embodiment of the invention]

 As shown in FIGS. 2 to 4, in the present invention, an upper wheel 5 is provided on an upper portion of a middle bar 4, a lower wheel 6 is slidably fitted on the middle bar 4, and the inner end of the rib 1 is a lower wheel. 5 and the inner end of the receiving bone 2 is rotatably connected to the lower wheel 6. In a well-known umbrella, one end of the auxiliary bone 3 is rotatably connected to the outer end of the receiving bone 2. This is an apparatus for preventing the destruction of the umbrella bone, which is rotatably connected to a connecting portion 11 which is connected and the other end is fixed to the middle position of the rib 1. With this structure, when the umbrella 1 is blown from the inside by the reverse wind and the rib 1 is blown up integrally with the cloth, the auxiliary bone 3 connected to the connecting portion 11 of the rib 1 is pulled upward and moves upward (FIG. 2). As shown by the phantom line). As a result, the rib 1 is held in a straight line, so that the rib does not bend and the rib does not break like a known umbrella. When folding an umbrella, as shown in FIG. 4, it does not create any operational difficulties.

FIG. 5 shows a modified embodiment of the present invention, in which the connection position between the auxiliary bone 3 and the main bone 1 and the receiving bone 2 is modified, and the auxiliary bone 3 is provided in the extension space of both. Thus, as in the above-described embodiment, an effect of preventing destruction is provided.

[0009]

[Effect of the invention]

 The umbrella bone destruction prevention device of the present invention, when the umbrella is rolled up in the headwind, smoothly moves the ribs upward and does not bend, thereby preventing damage to the umbrella bone or the joint. Offering effects.
