Miniaturized umbrella bone structure

Abstract

To provide a miniaturized umbrella rib structure which increases the convergence density of umbrella ribs, greatly reduces the volume after convergence, is easy to assemble, is easy to process, and is suitable for a multi-fold umbrella. [Solution] The miniaturized umbrella bone structure for an umbrella includes at least a long bone 3, a short bone 2, a vertebrae 6 and a coccyx 1, with a coccyx joint 4 between the coccyx and the vertebrae and a vertebrae joint 5 between the vertebrae and the long bones. The coccyx joint and the vertebrae joint allow the positions of the long bones, vertebrae and coccyx to be shifted, and since the umbrella bones are not directly connected by hinges, overlapping of positions can be avoided, the volume that can be accommodated can be efficiently reduced, and the space used can be reduced.

Description

[Technical field]

[0001] The present invention relates to a miniaturized umbrella bone structure, and more particularly to an umbrella bone structure that has a small volume after being closed. [Background technology]

[0002] Umbrellas are tools that people use to block wind and rain. When using them, they often encounter windy weather, and because the umbrella surface structure is unfolded, the wind force has a certain impact on the umbrella; therefore, to improve the structure of the umbrella frame, the material of the frame can be changed to metal to increase the strength and wind resistance.

[0003] In order to make it easier to carry, the volume of the umbrella after folding is of great importance. Therefore, a folding umbrella structure was designed, such as the fully automatic three-fold umbrella for sun and rain that can be operated with one hand, as disclosed in patent application 88213789.1. The purpose of this umbrella structure is to use an opening and closing device instead of the sliding tube of existing manual or semi-automatic three-fold umbrellas, and to open and close automatically with the control mechanism of the umbrella handle, and to operate it with only one hand.

[0004] On top of that, new structures that are easy to store are appearing one after another. For example, the bones of a multi-fold umbrella that can reduce the storage volume of an umbrella, disclosed in patent application 200920132358.4, include a first bone and a second bone that are connected in order from the inside to the outside, including multiple groups of radial bone units, and each radial group bone unit includes a first bone and a second bone that are connected in order from the inside to the outside; a first joint is fixed to the inside of the second bone, and the outside of the first bone is fixed to the first joint so that it can be removed. The first joint includes a base that is fixedly connected to the outside and the second bone, and a hinge part that is eccentrically provided on the base side, and the outside of the first bone is hinged to this hinge part. When the bones are stored, the first bone is eccentrically moved closer to the side of the second bone. When the umbrella skeleton of this folding umbrella is stored, the bones are folded in the circumferential direction, and the volume can be significantly reduced.

[0005] However, although this invention can reduce the volume by fitting the ribs, the connection structure of the ribs is realized by a hinge, so there is inevitably a misalignment between the ribs, which makes it difficult to close the ribs. This needs to be improved quickly, especially now when people's quality of life is gradually improving. Summary of the Invention [Problem to be solved by the invention]

[0006] In view of the problems of the conventional bone structure, the main objective of this utility model is to provide a bone structure that reduces the volume. The bone structure can be improved to increase the convergence density of the bones, and the volume after convergence can be significantly reduced. The second objective of this utility model is to provide a rib structure that reduces the volume. This mechanism is easy to assemble and process, and is suitable for multi-fold umbrellas such as two-fold, three-fold, and four-fold umbrellas. [Means for solving the problem]

[0007] This utility model is realized as follows: The miniaturized umbrella bone structure includes at least the long bones, short bones, ankle bones and tailbone. A tailbone joint is provided between the tailbone and ankle bone, and ankle bone joint is provided between the ankle bones and the long bones. The tailbone joint and ankle bone joint shift the positions of the long bones, ankle bones and tailbone, thereby preventing the umbrella bones from directly overlapping the positions of the hinges, and effectively reducing the convergence volume and the space used.

[0008] Furthermore, the tailbone joint includes a joint body, a tailbone insertion part, a line connection part, and a line hinge part. The tailbone insertion part fixes the tailbone, the line connection part connects the line, and the line hinge part hinges the line bone and is provided in a position offset from the tailbone insertion part, and the tailbone insertion part is fixed to the joint body and the line hinge part is hinged to the joint body, so that both are offset from each other when retrieving the umbrella, preventing overlap.

[0009] Furthermore, in order to maintain the strength of the ribs, the hinge portion of the ribs is hinged at the middle position of the joint body, and a coccyx insertion portion is provided on the side of the coccyx joint body to allow the coccyx to be inserted properly.

[0010] Furthermore, the joint body is provided with a coccyx joint reinforcing rib on the outer side where the coccyx hinge part is hinged, thereby increasing the strength of the coccyx joint while protecting the coccyx hinge.

[0011] Moreover, the short bone is hinged to the side wall of the long bone, causing it to be offset from the long bone. Moreover, the short bones hinge behind the side walls of the long bones, bend away from the long bones, and then extend back parallel to the long bones.

[0012] In other words, the circuit bone joint includes a main body, a circuit bone fixing part, a pull wire connecting part and a long bone hinge part; the circuit bone fixing part inserts and fixes the circuit bone, the pull wire connecting part connects the pull wire, and the long bone hinge part hinges the long bone and is offset from the circuit bone fixing part. The offset positions of the circuit bone fixing part and the long bone hinge part are not in a straight line, and the circuit bone fixing part is fixed to the main body and the long bone hinge part is hinged to the joint main body, so that the two parts can be prevented from overlapping when the umbrella is retrieved.

[0013] To increase the strength of the joint, a reinforcing rib is provided at the joint of the long bones. The reinforcing rib is provided at the outer end of the long bone hinge part, which strengthens the structure of the long bone hinge part and prevents the long bones from shifting during use, thereby increasing strength. Effect of the Invention

[0014] The technical advantages of this practical model are as follows: This practical new model uses the tailbone joint and the rib joint, so that the connecting parts of the umbrella bone are not directly hinged, but are connected by the joint, and at the same time, the joint shifts the position of the umbrella bone to avoid overlapping positions, so that the convergence volume can be effectively reduced and the space used can be reduced. This practical new model can effectively strengthen the umbrella bone structure, and is suitable for multi-fold umbrellas such as two-fold, three-fold, and four-fold.

[0016] In order to make the purpose, technical plan and advantages of the present invention more comprehensible, the present invention will be described in detail below with reference to the drawings and embodiments. It should be understood that the specific examples described herein are only used to illustrate the present invention, and are not intended to limit the present invention. EXAMPLES

[0017] As shown in Figures 1-6, this practical new umbrella bone structure reduces the volume. This embodiment is applied to the umbrella bone of a three-fold umbrella, which includes long bones 3, short bones 2, ribs 6, wires 7, pull wires 8 and tailbone 1; the long bones 3, short bones 2, ribs 6, wires 7, pull wires 8 and tailbone 1 can all be realized by conventional technology, so the description is omitted. The core of this practical new umbrella structure is that it is equipped with two joints: tailbone structure 4 and tailbone joint 5, among which, the tailbone joint 4 is installed between the tailbone 1 and the tailbone 6, and the tailbone joint 5 is installed between the tailbone 6 and the long bone 3. The tailbone joint 4 and the tailbone joint 5 shift the fitting positions of the long bones 3, the tailbone 6 and the tailbone 1, which can effectively reduce the convergence volume and reduce the space used.

[0018] Specifically, the tailbone joint 4 includes a main body 41, a tailbone insertion part 43, a pull wire connection part 45 and a tailbone hinge part 42. The tailbone insertion part 43 is inserted and fixed to the tailbone 1, and as shown in FIG. 3, the tailbone 1 is inserted from the tip insertion opening of the tailbone insertion part 43 and fixed to the tailbone insertion part 43; the tailbone connection part 45 connects the tailbone 7 (the tailbone 7 fits into the tailbone 6), and the tailbone hinge part 42 hinges the tailbone 6 continuously to the main body 41, so that the tailbone 6 can be adjusted in position when opening and closing the umbrella. The tailbone insertion part 43 is fixed from the front end of the joint main body 41 and fixed to the front end of the joint main body 41, making it easy to insert and fix the tailbone 1. Since the tailbone hinge part and the tailbone insertion part are offset and not in a straight line, it is possible to prevent overlap by offsetting the positions when both are fitted.

[0019] In normal cases, the rib hinge portion 42 is hinged at the middle position of the joint body 41 in order to maintain the strength of the ribs. In order to increase the strength of the coccyx joint while protecting the hinge of the cable bone, a coccyx joint reinforcing rib 44 is provided at the tip of the joint body 41 and at the outer position of the cable bone hinge part, which prevents the cable bone 6 from coming off and increases the stability of the cable bone 6.

[0020] The circuit bone joint 5 includes a main body 54, a circuit bone fixing part 51, a pull wire connecting part 53 and a long bone hinge part 52. The circuit bone fixing part 51 inserts and fixes the circuit bone 6, the pull wire connecting part 53 connects the pull wire 8 (the other side of the pull wire 8 connects to the short bone 2), and the long bone hinge part 52 hinges the long bone. The circuit bone fixing part 51 and the long bone hinge part 52 are not in a straight line but are fixed to the main body 54 and the long bone hinge part 52 is hinged to the main body 54, so that they can be shifted when fitting together to prevent overlapping.

[0021] In order to increase the strength of the joint, a reinforcing rib 55 is provided on the circumferential bone joint 5 at the outer end of the long bone hinge part 52, which strengthens the structure of the long bone hinge part 52, prevents the long bone from shifting position during use, and increases strength.

[0022] As shown in FIG. 5, in order to prevent the long bone 3 and the short bone 2 from overlapping, the short bone 2 is hinged to the side of the long bone 2 and is offset from the position of the long bone. Specifically, the short bone 2 is connected to the side of the long bone 3 and is bent away from the long bone to extend parallel to the long bone, so that the short bone 2 and the long bone 3 can be arranged in parallel after being stored and do not take up much space.

[0023] Furthermore, as shown in Figure 6, when folded, the tailbone insertion part 43 is offset from the joint body 41 due to the role of the tailbone joint 4 and the ankle joint 5, and at the same time the ankle fixing part 51 is offset from the body 54, so instead of being placed one on top of the other as in the conventional structure, the ankle 6 and the tailbone 1 can be shifted in position. This also significantly reduces the volume of the umbrella bones after folding, making it possible to reduce the space occupied by the umbrella.

[0024] At the same time, the structure of the coccyx joint 4 and the ankle joint 5 effectively maintains the coccyx 1, ankle 6 and long bones 3, strengthens the ankle bone structure, and allows the ankle bone to maintain a certain stability.

[0025] The above description is the specific embodiment of the present invention and the technical principles used. Any modifications based on the concept of the present invention, even if the functions do not exceed the spirit of the craftsmanship contained in the description and drawings, shall all be included in the scope of the present invention.
