Description

  The present invention relates to a kind of umbrella bone structure, and more particularly to an umbrella bone positioning structure that secures its assembly and quality of use by making the supporting connection of the umbrella bone difficult to drop off.

  Rain umbrellas or parasols are articles that are commonly used in the lives of modern people, and are quite convenient for avoiding rain and wind or solar radiation. However, in general, the failure rate of umbrellas is considerably high, and the main cause thereof is that the connection between the umbrella bones of the umbrella cannot withstand various customary operations or poor use environments. As shown in FIGS. 8, 9 and 10, the known umbrella has a middle rod 90 connected to the handle, and can slide on the first rod 91, the second wheel 92, and between the middle rod 90. A held spring 93 is provided, the second wheel 92 is pivotally mounted on the rib 94, the outer end of the rib 94 is pivoted on the master bone 95, and a pulling rod 96 is pivoted on the first wheel 91. Then, the outer end of the pulling rod 96 is locked to the pivoting means 97 of the receiving bone 94, and the engagement between the pulling rod 96 and the receiving bone 94 is performed by the locking portion 98 of the outer end of the pulling rod 96. It is formed by engaging with a pin 99 pivoted on.

  The above-mentioned umbrella structure can achieve the basic operation of the connection between the umbrella bones, but generally, when a consumer purchases an umbrella, in order to confirm the structure strength of the umbrella, it is customarily arranged in a circular arrangement. Try pulling four points on the bone 94. As a result, the receiving bone 94 receives a downward pulling force F, thereby generating an acting force in which the pivoting means 97 presses against the pulling rod 96, whereby the pin 99 of the pivoting means 97 is pulled. May be disengaged from the position of engagement with the engagement portion 98, and this causes a serious defect in quality (defective product). Further, when the umbrella is used in a windy or typhoon, when the wind force acts on the umbrella surface (not shown, the umbrella surface is connected to and supported by the main bone 95), the main bone 95 and the rib 94 are In either case, the pin 99 may receive downward pressure, and the pin 99 may be disengaged from the engagement position with the engagement portion 98 and fall off from the engagement portion 98. If the wind is strong and the umbrella cannot be held firmly, and the umbrella swings and the engagement portion 98 of the receiving rib 94 and the pulling rod 96 is disengaged, the connection strength of the umbrella frame is weakened and supported in an equilibrium state. It can no longer be done and can be dangerous. For this reason, it is necessary to solve the problem of the connection strength and safety of the umbrella bone of the umbrella.

  The present invention provides an umbrella bone positioning structure that has both practicability and safety, in contrast to the above-mentioned drawback of the umbrella bone connection positioning failure of the rain umbrella structure and the fact that the structure is not ideal in safety design.

  It is an object of the present invention to provide a kind of umbrella bone positioning structure, which considerably stabilizes and ensures the engagement of the receiving bone and the pull bar, prevents mutual dropout, and the structure of the umbrella. The structure increases the quality and service life.

  The umbrella bone positioning structure of the present invention is a structure in which the engagement between the receiving bone and the pulling bar is considerably stabilized and ensured, so that they do not fall off each other, and the structural quality and service life of the umbrella are increased. .

  The umbrella bone positioning structure of the present invention is a structure in which the umbrella does not form a pull-out of the pull bar due to use by a consumer in any test or in a poor environment, thereby improving the overall structural strength and safety.

  The present invention includes an intermediate rod and an umbrella bone mechanism, and the intermediate rod is provided with a first and second skull holes, and the umbrella bone mechanism includes a plurality of receiving bones and a pulling rod, and the receiving bone is the second rod. A pivot means is provided on the handle, a pivot means is provided on the rib, a convex ear is provided on the pivot means, a pin and a stopper block are provided on the convex ear, and one end of the pull rod is pivoted on the first pole. And the other end of the pulling bar is pivotally connected to the pin of the pivoting means, and the stopper block has a restricting action on the movement of the pivoted end of the pulling bar with respect to the pivoting means. The stick is prevented from falling off, increasing the structural strength, safety of use and service life of the umbrella.

  As shown in FIGS. 1 to 5, the umbrella bone positioning structure of the present invention includes an intermediate rod 10 and an umbrella bone mechanism 20. A first wheel 11 and a second wheel 12 are slidably fitted to the center rod 10, a plurality of fitting grooves 111, 121 are provided in the first wheel 11 and the second wheel 12, and the first wheel 11. A spring 13 is held between the second wheel 12 and the second wheel 12. The umbrella bone mechanism 20 includes a plurality of receiving bones 21, a main bone 22, and a pulling rod 23, and the receiving bone 21 is pivotally provided in the fitting groove 121 portion of the second wheel 12, and the pivoting means 24 is provided on the receiving bone 21. And the end pivot means 25 are fitted. Among them, a convex ear 241 is provided at the bottom end of the pivot means 24, and a perforation 242 parallel to the axial direction of the pivot means 24, pins 243 at both ends of the perforation 242, and a stopper block 244 are provided on the convex ear 241. ing. The main bone 22 is pivotally mounted on a third wheel (not shown) above the intermediate rod 10, pivot means 221 is fitted to the main bone 22, and a convex ear 222 is provided at the bottom end of the pivot means 221. The convex ear 222 is pivotally connected to the end pivoting means 25 of the receiving bone 21, whereby the receiving bone 21 and the main bone 22 are connected. The pulling bar 23 is a metal bar, and a hook 231 is provided at one end thereof. The hook 231 is inserted into the fitting groove 111 of the first wheel 11 and pivoted on the first wheel 11, and An engaging portion 232 is provided at the other end, and the engaging portion 232 is inserted from the perforation 242 of the pivoting means 24 at an appropriate angle and engaged with the pin 243, and thus the umbrella bone mechanism 20 and the middle rod 10 are engaged.
