  The upper runner 2 is rotatably provided at the upper end of the middle rod 1 and includes an upper runner body 21, an engagement member 22, and a movable upper runner 23. The upper crossbone main body 21 has a hollow cylindrical shape, and includes an insertion portion 211 into which the center rod 1 is inserted, and the center rod 1 is rotatably inserted. In addition, a first pivot attachment portion 212 and a first engagement portion 213 are formed on the upper and lower ends of the upper wheel body 21 respectively.

The engaging member 22 is attached to the upper wheel body 21, and a second pivotally attached portion 221 and a protruding portion 222 are formed on the upper and lower ends, respectively. The second pivot part 221 is formed corresponding to the first pivot part 212. A first fitting portion 223 is formed along the axis Y between the protruding portion 222 and the first pivot attachment portion 212. In the embodiment, the first fitting portion 223 is an annular groove.

  The movable upper wheel 23 includes a second fitting portion 231 that fits into the first fitting portion 223 and rotates in conjunction with the first fitting portion 223. In the embodiment, the second fitting portion 231 is an annular protrusion, and the annular protrusion is fitted into the annular groove and rotates in conjunction with the annular protrusion. Therefore, the movable upper wheel 23 is provided so as to be rotatable with respect to the center rod 1 about the axis Y.

  As disclosed in FIGS. 1 to 5, the bottom roller 3 in the embodiment is provided on the middle rod 1 so as to be rotatable, and includes a pulley seat 31, a bottom rod body 32, and a movable bottom rod 33. A pulley ring 6 is provided on one side of the pulley seat 31, and the drawn wire 7 connected to the upper wheel body 21 contacts the rope ring 6.

  The pulley seat 31 has a hollow cylindrical shape and includes an insertion portion 311 along the axis Y. Moreover, the 2nd engaging part 312 and the 1st connection part 313 which engage with the 1st engaging part 213 are provided in the both ends of the pulley seat 31. FIG.

  The bottom wheel body 32 is connected to the pulley seat 31. In addition, a second connection part 321 connected to the first connection part 313 is provided. An annular fitting portion 332 corresponding to the fitting insertion portion 311 is formed on the movable bottom rod 33, and the movable bottom rod 33 is rotatably inserted into the fitting insertion portion 311. For this reason, the movable bottom rod 33 is provided so as to be rotatable with respect to the middle rod 1 about the axis Y.

  The umbrella cloth support portion 4 includes a plurality of umbrella bones 41 connected to the movable upper and lower skulls 23 and 33, and an umbrella cloth 42 that covers the outer surface of the umbrella bones 41.

  According to the above structure, when the umbrella is opened, the upper and lower body bodies 21 and 32 are connected by the engagement of the first engaging portion 213 and the second engaging portion 312 and are not rotated because they are positioned. . The umbrella cloth support part 4 is interlocked with the movable upper wheel 23 and the movable lower wheel 33. Therefore, the movable upper wheel 23 and the movable lower wheel 33 rotate relative to the middle rod 1 in synchronization.

  As shown in FIG. 6 and FIGS. 1 to 5, in the embodiment, the positioning portion 5 is formed at the upper end edge portion of the lower skull body 32, and at a position corresponding to the positioning portion 5 of the movable bottom rod 33.

  What should be noted is that the outer periphery of the intermediate rod 1 is formed in an octagon. Further, the inner circumferences of the bottom wheel body 32 and the top wheel body 21 are octagons similar to those of the center rod 1. In other words, both have a shape having an angle. For this reason, a certain force of interference occurs between the inner peripheral surface of the lower crossbone main body 32 and the upper crosspiece main body 21 and the outer peripheral surface of the center rod 1, and the lower crosspiece main body 32 and the upper crosspiece main body 21 are movable upward. There is no arbitrary rotation with respect to the potter's wheel 23 and the movable potter's wheel 33. Of course, the shape is not limited to an octagon, and may be, for example, a concave shape, a convex shape, or any other geometric shape. By making the inner circumferences of the lower wheel body 32 and the upper wheel body 21 to have the same concave shape, convex shape, or any other arbitrary geometric shape, interference of a certain force is generated with respect to the intermediate rod 1.

  Further, the first engaging portion 213 and the second engaging portion 312 are engaged with each other. However, the connection structure is not limited to this. In the embodiment, the first engaging portion 213 and the second engaging portion 312 have structures that engage with each other. Therefore, in the state in which the umbrella is opened, the upper skull body 21 and the lower skull body 32 are connected to each other and positioned to prevent the lower skull body 32 from rotating arbitrarily.

  The first connecting part 313 and the second connecting part 321 are connected by fitting, but are not limited to such a structure. For example, the first connecting portion 313 and the second connecting portion 321 may be connected by engagement, or may be screwed as disclosed in FIG.

  As shown in FIG. 8, when the umbrella according to the present invention is opened and used, the movable upper and lower crosspieces 23 and 33 have a function of rotating with respect to the middle rod 1. When a strong wind is received, or when the tip of the umbrella bone 41 hits a person and an impact from the outside is received, the umbrella support 4 is interlocked with and synchronized with the movable upper frame 23 and the movable lower frame 33. Then, it rotates relative to the middle rod 1. For this reason, the umbrella bone 41 is not damaged by receiving external force, and the service life of the umbrella can be extended. Further, the tip of the umbrella bone 41 is prevented from hitting a person and damaging the eyes and face.

  What should be noted here is that when the movable armpit 33 rotates in the umbrella according to the present invention, the armor body 32 and the pulley seat 31 do not rotate. For this reason, even if the movable armpit 33 rotates, the drawn line does not get tangled and the rotation does not stop.

  The above is a preferred embodiment of the present invention, and does not limit the scope of implementation of the present invention. Therefore, any changes, modifications, etc. that are made within the spirit of the present invention and have an equivalent effect on the present invention shall belong to the scope of the claims for registration of the utility model of the present invention.
