Description

  The present invention extends to a kind of umbrella. In particular, it extends to the improvement of the spring structure for umbrella opening with a kind of reinforced automatic umbrella opening elastic structure.

  In many existing automatic umbrella nests, sliding caging pipes have an umbrella opening spring between the middle nest and lower nest of the middle rod, but the spring is exposed to the outside and closes the umbrella The spring is compressed by pulling the lower nest down. When the umbrella is opened, the spring is extended by its own tension, the distance between the middle nest and the lower nest increases, and the parent bone opens. Since the spring for opening the umbrella is exposed, the shape is not clean and it is necessary to prevent the hand from being pinched.

  The technical problem to be solved by the present invention is to provide an automatic umbrella nest containing a spring for opening an umbrella and a structure for extending the spring.

  The present invention is a technical solution that solves the above technical problem is to design an enhanced automatic umbrella-opening elastic structure. The structure is connected to the middle and lower nests of the center rod, and is sandwiched between the middle and lower nests. , A caging pipe covering the middle rod, and an umbrella opening spring sandwiched between the caging pipe and the lower nest.

  By installing the underpipe portion in the above-mentioned caging pipe, the spring for opening the umbrella is completely contained in the pipe, and the spring for opening the umbrella is lengthened.

  The up-pipe part is installed under the above-mentioned caging pipe, and the ring-shaped projecting part installed under the up-pipe part and the upper part of the spring for opening the umbrella.

  The aforementioned nest has a tubular portion underneath, and an annular stepped portion under the tubular portion, which hits the tubular portion and the annular protruding portion of the caging pipe.

  The pipe in the bottom portion of the lower nest has an annular staircase portion that supports the spring for opening the umbrella, and the spring for opening the umbrella is sandwiched between the annular protrusion and the annular staircase portion.

  Compared with the existing technology, the enhanced automatic umbrella-opening elastic structure of the present invention can be used more safely because the spring for opening the umbrella is completely hidden, the parent bone is cleaner, and the hands are not pinched. At the same time, since the caging pipe can be installed longer, the space becomes longer when opening the umbrella, the elasticity becomes stronger, and labor is saved when opening the umbrella.

It is a local figure of the state which closes the umbrella regarding the augmentation automatic umbrella opening elastic structure of this invention. It is a local view at the time of opening the umbrella regarding the enhanced automatic umbrella opening elastic structure of the present invention. It is a three-dimensional view of an assembled state related to the enhanced automatic umbrella opening elastic structure of the present invention. It is an exploded view regarding the enhanced automatic umbrella opening elastic structure of the present invention. It is a component diagram regarding the reinforced automatic umbrella opening elastic structure of this invention. Among them, a is a sectional view of the lower nest, b is a sectional view of the caging pipe, and c is a sectional view of the middle nest.

  The enhanced automatic umbrella opening elasticity structure of the best embodiment of the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 4 and 5, the enhanced automatic umbrella opening elastic structure of the embodiment of the present invention is such that the bottom pole is connected to the middle rod 5, the middle nest 3 and the lower nest 1, and between the middle nest 3 and the lower nest 1. Sandwiched between. The lower pole includes a caging pipe 2 that covers the middle rod 5 (see FIGS. 1 and 2), and an umbrella-opening spring 4 that is accommodated in the caging pipe 2 and the lower web 1 and on which the middle rod 5 is mounted. . A nest 3 is fixed to the top of the caging pipe 2. The caging pipe 2 and the middle nest 3 can move integrally with the lower nest 1. A structure in which the umbrella opening spring 4 is wrapped in an underpipe portion 2c installed in the caging pipe 2, and the umbrella opening spring 4 is elongated in accordance with the upward movement of the caging pipe 2 and the nest 3. It is. An up pipe portion 2a is installed on the upper portion of the caging pipe 2, and an annular projecting portion 2b is provided below the up pipe portion 2a. The annular projecting portion 2b is in contact with the upper portion of the umbrella opening spring 4. The nest 3 includes a tubular portion 3a extending downward, and a tubular staircase portion 3b is provided below the tubular portion 3a. The tubular portion 3a contacts the annular projection 2b of the caging pipe 2. A pipe 1a in the bottom of the lower nest 1 has an annular staircase 1b that supports the lower part of the spring 4 for opening the umbrella. An umbrella-opening spring 4 is sandwiched between the annular projecting portion 2b and the annular staircase portion 1b. The automatic umbrella-opening elastic structure allows the upper part of the umbrella-opening spring 4 to be accommodated in the caging pipe 2 so that the umbrella-opening spring 4 can be extended.

  Next, the operation and effect of the enhanced automatic umbrella opening elastic structure of this embodiment will be described.

  As shown in FIG. 1, the umbrella-opening spring 4 is compressed by an external force in the umbrella-closed state of the enhanced automatic umbrella-opening elastic structure of the present embodiment. The caging pipe 2 is hung on the inner pipe 1a of the lower nest 1, and the spring 4 for opening the umbrella is guided to ensure the smooth opening and closing of the umbrella. Because there is a caging pipe 2, the spring 4 for opening the umbrella can be lengthened. Umbrella opening spring 4 is not exposed to the outside and there is no damage to both hands. The lower nest 1 may be made longer by integrally processing the handle of the lower nest 1. It doesn't have to be a short nest like an existing automatic umbrella. Thereby, the user can save power when grasping to close the umbrella.

  As shown in FIG. 2, when the umbrella is opened with the enhanced automatic umbrella opening elastic structure of the present invention, the pressure of the umbrella opening spring 4 is released, and the umbrella is expanded. At that time, the spring 4 for opening the umbrella pushes the caging pipe 2 upward, and the nest 3 slides along the middle bar 5 to the top of the lower nest 1, but the caging pipe 2 is the inner pipe 1a of the lower nest 1. Is not out. At that time, the outside of the caging pipe 2 and the inside of the pipe 1a in the lower nest 1 overlap and play a role of normal sliding without shaking. It can be seen that the caging pipe 2 is raised and the space for the umbrella opening spring 4 is lengthened. Moreover, the umbrella-opening spring 4 is sealed by the caging pipe 2.

  Although the above-mentioned content is a preferred embodiment of the present invention, the present invention is not limited to the above-described embodiment. For engineers in this field, the present invention may have various changes. Modifications, replacements and improvements based on the concept and principle of the present invention are included in the scope of protection of the present invention.
