Automatic opening and closing umbrella

This creation department is about an improvement of the automatic opening and closing umbrella structure, which is mainly for the improvement of the structure of the rod unit in the automatic opening and closing umbrella, so that the improved automatic opening and closing umbrella is more convenient to complete the final compressed umbrella movement. And greatly reduce the risk of compressed umbrellas.

The structure of the more common automatic open umbrella is shown in Figure 1. Taking a three-fold umbrella as an example, it is generally provided with a control unit (10) in the umbrella grip (20), and the middle rod unit (30). An open umbrella spring (60) is disposed therein, and the movable nest (40) engaged with each rib (70) is fixed to the upper nest (41) by one end of the pulley, and the other end is traversed by the upper nest ( 41) Fix the first drawstring (51) of a bullet (50) behind the pulley. The control unit (10) is mainly composed of a control ring body (11), a control column (12) and a button (13), and the control column (12) is pivoted on a body having a hollow interior. Controlling the bottom of one side of the ring body (11), and the button (13) is disposed on the side opening of the umbrella grip (20) and exposed, thereby controlling the structure of the middle rod unit (30) for retracting and controlling the ring body (11) one of the outer ends of the side is provided with a small spring (111) and a pillar (112) is supported for clamping the movable nest (40) to keep the umbrella positioned in a folded state; in addition, the control column (12) using a pivot (121) coupled to the bottom of the control ring body (11) near the button side, and is provided with a torsion spring (122) to maintain the control column (12) in a horizontal normal state, when the umbrella When the compression is ready for use, the movable nest (40) is positioned by the protrusion (112) of the control ring body (11), while the control column (12) is subjected to the second folding rod of the middle rod unit (30) ( 32) The downward pushing is formed into a slant shape, and the bullet (50) is pressed by the inner tube (34) disposed in the third folding rod (33) and the elastic piece (311) is pushed and buckled to the middle rod unit. (30) The first fold of the rod (31) on the buttonhole; the first press button ( 13) When the control ring body (11) is pushed in, the protrusion (112) is disengaged from the buckle of the movable nest (40), and is completed by the open spring (60) in the middle rod unit (30). When the umbrella is automatically opened, the control column (12) is restored to the horizontal normal state at this time; when the umbrella is to be received, the button (13) is pressed again, and the control column (12) is pressed against the bullet (50). Pushing it away from the buckle of the first folding rod (31), so that the movable nest (40) forms a movable shape, and under the action of the umbrella spring (71) on each rib (70), The ribs (70) are automatically folded together with the umbrella surface (not shown) and the movable nest (40) is displaced downward, and then the middle rod unit (30) is moved to the umbrella grip by the umbrella top (20). The compression is completed and the umbrella is completed. However, the automatic opening and closing umbrella has the following missing points in actual use:

1. When pressing the button to close the umbrella, only the ribs can be folded together with the umbrella surface, while the middle rod unit still maintains the longest length of the three-folded rod, so the women or children with shorter hands are used It is inconvenient for the hand to press the middle rod unit to the umbrella grip to compress the umbrella.

2. Since the length of the open spring is from the first folded rod to the top of the third folded rod, the strength and elasticity are not small. Therefore, the user's hand must use a large force to compress the umbrella. As a result, for women or children with less hand strength, it is difficult to compress the umbrella.

3. Because the strength and elasticity of the open-spring spring are not small, when the force is applied or the action is slightly wrong, the compressed open-spring spring will re-bounce the middle rod unit with great force. It often causes injury to the user's hands or other parts of the body.

It can be seen from the foregoing that the conventional automatic opening and closing umbrella has an inconvenience and danger in use due to the unsatisfactory structural design, and needs to be improved.

The main purpose of this creation is to shorten the middle rod unit while the movable nest and the third folding rod are simultaneously downwardly retracted when the umbrella is closed, thereby making it easier to reduce the risk when the umbrella is compressed and greatly reducing the risk.

Another purpose of this creation is to shorten the length of the open-spring spring to reduce its strength and elasticity, but to fully stretch the middle rod unit, thereby avoiding injury when compressing the umbrella.

The creation of the above-mentioned function automatically opens and closes the umbrella folding structure, which is mainly for the improvement of the structure of the middle rod unit, and a turn sleeve is arranged on the bottom end of the middle folding rod of the middle rod unit. At the top of the second folding rod, a inner plug with a pulley is fixed, and a first pulling rope is arranged, so that one end is fixed to the top end of the bullet, and the other end is passed up and around the pulley of the inner plug. The slot is then fastened from the bottom to the bottom of the third folding rod and then fixed upward to the bottom of the upper nest. The second cable is further provided with one end fixed to the top of the inner plug and the other end is wound upward. After passing through the pulley in the upper nest, it is fixed to the top of the movable nest, and the bottom end of the open spring in the middle rod unit is abutted against the first folding rod, and the top end is abutted against the second folding rod. The bottom of the stopper.

By adopting the structure, when the umbrella is opened, the button is pressed, and the second folding rod is pushed up by the open spring, and the third folding rod and the movable nest are simultaneously used by the first pulling rope and the second pulling rope respectively. Pushing up to complete the opening operation, and when the umbrella is closed, pressing the button again, the pulling force of the first pulling rope is released to form a slack state, and the movable nest and the third folding rod are pushed downward by the umbrella spring, so that The third folding middle rod is completely fitted around the second folding rod to shorten the length of the middle rod unit, thereby facilitating the completion of the final compression and closing operation, and greatly reducing the risk of compressing the umbrella, for the purpose thereof.

Please refer to Figure 2, the creation of the automatic opening and closing of the umbrella in the bar is also three For example, a folding umbrella includes a control unit (10), an umbrella grip (20), a set of middle rod units (30), a movable nest (40), and an upper nest (41). a bullet (50), an open umbrella spring (60), a plurality of ribs (70) and an umbrella spring (71); the control unit (10) is disposed in the umbrella grip (20), which is mainly A control ring body (11) and a button (13) disposed on the side opening of the umbrella grip (20) and exposed at a bottom portion of the hollow body are provided at the bottom of the control ring body (11).
