Description

  The present invention relates to an umbrella surface rotating structure of an umbrella device, and the umbrella surface freely rotates around a center rod as a support shaft, so that the impact of the umbrella bone is weakened and protected even when hit by a strong wind, an object or a person. Is.

  The structure of the umbrella generally includes an intermediate rod, an upper skull installed at the top of the intermediate rod, a lower skull that slides along the axis of the intermediate rod, an upper and lower umbrella bone, and an umbrella. It consists of an umbrella surface that is fixed over a bone. Use the umbrella in the open position to avoid rain and sunlight.

  The problem to be solved is that, in the case of heavy rain with strong winds, the resistance against the umbrella surface is considerably large, and when the umbrella surface is blown by the wind, the umbrella bone is twisted and broken. Moreover, even if it hits a person or an object, the umbrella surface is similarly subjected to torsional force, and the umbrella bone or the middle rod is damaged.

  The present invention includes a middle rod, an upper skull fixed to the uppermost end of the middle rod, a lower skull sliding along the middle rod, an umbrella bone connecting the upper and lower skulls, and an umbrella bone. It is composed of an umbrella surface that covers. Of these, the upper wheel is composed of an upper wheel base and an upper wheel base that moves with the upper wheel base, and the lower wall is composed of a lower wheel base and a lower wheel base that moves with the lower wheel base. The umbrella bone is fixed on the upper and lower racks. The upper and lower cradle bases rotate on the upper and lower cradle bases, and the umbrella bones are fixed by the upper and lower cradle bases. Therefore, when the umbrella is opened, the lower cradle support is fixed on the middle bar, and the upper cradle base is fixed at the uppermost end of the middle bar. When the umbrella receives an external force, the main feature of the umbrella bone is that the upper and lower cradles rotate with the middle rod as a fulcrum.

  The umbrella surface rotating structure of the umbrella device of the present invention has the advantage of protecting and protecting the impact of the umbrella bone when it hits a strong wind, an object, or a person by freely rotating the umbrella surface around the center rod. Besides, it also has a moving picture effect when the umbrella is rotated.

Example 1
As shown in FIG. 1, the umbrella surface rotating structure of an umbrella device according to the first embodiment of the present invention includes an intermediate rod 1, an upper skull 2 fixed to the uppermost portion of the intermediate rod 1, and an axis of the intermediate rod 1. And the umbrella frame 4 that connects the upper and lower skulls 2 and 3, and the umbrella surface 5 that covers the umbrella bone 4 and is fixed to the umbrella bone 4.

  As shown in FIGS. 2 and 4, the top wheel 2 is composed of a top wheel base 21 and a top wheel base 22 movable on the top wheel base 21. The upper rail support 21 is fixed to the uppermost end of the middle rod 1, and a convex ring 211 for positioning the upper rail 22 is installed on the outer wall thereof, and the engaging tank 212 is located above (or below) the convex ring 211. Is molded. Since the inner diameter of the upper cradle base 22 is larger than the outer shape of the upper cradle base 21, the upper cradle base 22 rotates between the convex ring 211 of the upper cradle base 21 and the engaging tank 212, and the C-shaped ring 23 is engaged. After being fitted to 212, the upper wheel base 22 is fixed in the upper axis direction of the upper wheel base 21. A connecting tank 221 connected to the ribs 41 is distributed around the circumference of the upper rack base 22, the umbrella lid 6 is fixed to the top of the upper rack base 21, and the lower part of the upper rack base 21 is a convex column 213. Is installed.

  As shown in FIG. 3 and FIG. 4, the bottom rack 3 is composed of a bottom rack base 31 and a bottom rack base 32 that is movable on the bottom rack base 31. The lower rack support 31 is fitted to the middle bar 1 and slides along the middle bar 1. Further, a positioning hole 314 that is aligned with a positioning piece in the middle rod 1 is installed in the bottom rack base 31, and a convex ring 311 of the bottom rack base 32 is installed on the outer wall of the bottom rack base 31. A hooking tank 312 is formed above (or below). Since the inner diameter of the lower cradle base 32 is larger than the outer shape of the lower cradle base 31, the lower cradle base 32 rotates between the convex ring 311 of the lower cradle base 31 and the engaging tank 312, and the C-shaped ring 33 is engaged. After being fitted to 312, the bottom cradle 32 is fixed in the axial direction of the bottom cradle base 31, and similarly, a connecting tank 321 connected to the ribs 42 is distributed around the circumference of the bottom cradle base 32.

  As shown in FIG. 4, the ribs 41 and the ribs 42 of the umbrella bone 4 are fixed on the connecting tank 221 and the connecting tank 331 of the upper and lower cradle bases 2 and 32, respectively. Since the upper and lower cradle bases 22 and 32 rotate on the upper and lower cradle bases 21 and 31, the upper and lower cradle bases 22 connected to the umbrella bone 4 when the umbrella surface receives an external force. 32 rotates with respect to the center rod 1, weakens the force received by the umbrella bone 4, and protects the receiving bone 41 and the receiving bone 42.

(Example 2)
As shown in FIG. 5, in the umbrella surface rotating structure of the umbrella according to the second embodiment of the present invention, the convex ring 211 of the upper rack base 22 is formed on the outer wall of the upper rack base 21 of the upper rack 2, and the convex ring 211 is formed. At least three notch tanks 214 are installed in the direction of the upper wheel support shaft. Due to the installation of the notch tank 214, the upper rack support is provided with a certain elasticity. In addition, a hooking table 215 is installed on the upper rack support 21 where the notch tank 214 is installed. An inclined surface 2151 is formed in the hooking table 215 in an inward direction relative to the convex ring 211, so that the upper rail 22 is smoothly engaged with the upper rail holder 21 along the inclined surface 2151. If the engagement is too deep, the upper cradle base 21 contracts inward due to the notch tank 214, and after the upper cradle base 22 is completely fitted to the upper cradle base 21, the upper cradle base 21. At this time, the hook base 215 is fixed to the hook base 21 in the axial direction by the action of the pole base 22, and the interval between the convex ring 211 and the hook base 215 is It is larger than the height of the upper wheel base 22.

  As shown in FIG. 6, a convex ring 311 of the bottom rack base 32 is installed on the outer wall of the bottom rack base 31 of the bottom rack 3 of this embodiment. At least three notch tanks 313 are installed in the axial direction on the bottom of the bottom 31 of the convex ring 311 (or below), and the bottom of the bottom 31 is provided with a certain elasticity by the installation of the notch 313. Be specific. A hooking table 315 is further installed on the bottom support 31 on which the notch tank 313 is installed. The hooking table 315 is formed with an inclined surface 3141 from the outside of the convex ring 311 toward the inside, whereby the lower table 32 is engaged with the lower table 31 along the inclined surface 3141. If the engagement is too deep, the lower cradle base 31 contracts inward due to the notch tank 314, and after the lower cradle base 32 is completely fitted to the lower cradle base 31, the lower cradle base 31. At this time, the hanging table 315 is fixed to the lower receiving table 31 in the axial direction by the action of the lower drawing table 32, and the interval between the convex ring 311 and the hanging table 315 is as follows. It is larger than the height of the bottom table 32.

  The upper wheel base 22 and the lower wheel 32 in this embodiment rotate with respect to the middle rod 1. For this reason, when an external force is applied to the umbrella surface, the upper and lower skull bases 22 and 32 rotate the umbrella bone 4 to protect the umbrella bone from damage, and if a picture is drawn on the rotating umbrella surface, It also has an effect.
