The outer ends of the main umbrella ribs and the outer edge of the umbrella fabric are connected. The main umbrella ribs are arranged on the basis of the reference line, so that the umbrella ribs can be supported effectively according to a structural form of the one-piece umbrella fabric to form an arc-shaped ceiling formed after an umbrella is unfolded, namely an umbrella shape, and the umbrella ribs and the umbrella fabric can be folded effectively after the umbrella is folded.

Description

  The present invention relates to an umbrella bone structure for a single-piece umbrella surface related to an umbrella bone structure.

In general, traditional umbrella surfaces are manufactured by cutting and sewing fabrics processed for umbrellas.
As shown in FIG. 1, the fabric is cut to create a triangular fabric A, and one side B of the triangular fabric A is folded in and then stitched together to form the entire umbrella surface.
However, attachment of such a structure is relatively complicated, and a large amount of manual sewing is required, which reduces the processing efficiency of the umbrella surface.

In order to simplify the structure of the umbrella surface, an integrated umbrella surface was invented.
There exists a thing like the umbrella surface described in patent documents 1, and it cuts and constitutes cloth.
Although such an umbrella surface greatly simplifies the manufacture of the umbrella surface, it is necessary to construct a three-dimensional umbrella by stretching the umbrella surface with an umbrella bone.
Therefore, the strength requirement of the umbrella bone becomes higher. With the current umbrella bone structure, it is difficult to satisfy the requirements of an integrated umbrella surface.

China Patent Application No. 200710074654.9

What has become clear by the inventor's research is that the deformation, curvature or twist of each umbrella bone is not the same.
If you look closely, the umbrella surface is composed of warp lines (warp) and weft lines (weft). As a result, meridians and parallels intersecting vertically and horizontally are arranged on the umbrella surface.
Meridians and latitudes are composed of one rectangular frame. The tension generated at different positions on the umbrella surface during the process of receiving the tension of the umbrella bone is not the same.
For this reason, in the process in which the umbrella bone supports the single umbrella surface, the reaction force generated by the umbrella surface received by each umbrella bone supporting the umbrella surface is not the same, and each umbrella bone is deformed, curved or twisted. Are not the same.

  It is difficult to achieve a good opening / closing effect of a single-sided umbrella face unless tensions at different angles of the umbrella face are taken into consideration in light of a general umbrella bone installation method.

  An object of the present invention is to provide an umbrella structure with a single-piece umbrella surface. This umbrella bone structure has sufficient strength to support the single umbrella surface, and can achieve a good umbrella opening and closing effect.

In order to achieve the object of the present invention, the umbrella bone structure of the present invention has an umbrella bone structure including an umbrella bone and a single umbrella face.
The umbrella bone is centered on the middle rod, and is used as a reference line along the diagonal direction of the thread of the single umbrella surface or along the meridian and parallel directions.
The umbrella bone has at least four master bones, and each master bone is placed on the reference line or symmetrically on the reference line.
The outer end of the umbrella bone is joined to the tip of the outer edge of the single-piece umbrella surface or a connecting part.

The umbrella bone installed along the reference line formed along the diagonal line of the umbrella surface from the center (center bar) of the single-piece umbrella surface has the best stretchability of the umbrella surface.
It can be opened by pulling the umbrella surface as much as possible, and an arcuate apex can be formed when the umbrella is opened.
The umbrella shape of an open umbrella can be held, and when the umbrella is folded, it can be folded smoothly.

Umbrella bones installed symmetrically with respect to the reference line do not have the maximum elasticity of the umbrella surface, but the elasticity of the umbrella surfaces corresponding to two symmetrical umbrella bones are completely the same.
In addition, the supporting force of the umbrella bone is the same, and the elasticity of the umbrella surface is also the same.
Umbrella bones installed in the meridian and latitude directions of the umbrella surface have the minimum deformation of the corresponding umbrella surface, but the distribution of the umbrella bone on the umbrella surface is symmetrical with respect to the reference line.
That is, symmetrical umbrella bones have the same supporting force, and the deformation of the umbrella surface at the umbrella bone position is the same.

As a result, the single umbrella surface is opened to form an umbrella shape, and after being folded, the umbrella bone and the umbrella surface are completely stored.
The above-mentioned symmetry refers to the symmetry of the arrangement position of the umbrella bone with the axial symmetry or the point symmetry with respect to the umbrella bone.

  The umbrella bone described above has a longest length when the distance between the respective edges and the center of the center bar is equal, or when the umbrella bone arranged on the reference line located in the diagonal direction is the longest, Umbrella bones arranged in the direction of the latitude will be the shortest to achieve the balance of the umbrella bone support.

  Umbrellas arranged in the meridian or parallel direction of the umbrella surface when the center distance between the edge of the umbrella surface arranged on the reference line located in the diagonal direction and the center rod is the shortest when the umbrella bones are equal in length The center distance between the edge of the surface and the center rod is the longest.

A branch structure is formed at the end of the umbrella bone described above, and the tail portion of the parent bone is branched to form at least two tailbones.
The coccyx is two symmetrical with respect to the reference line, extends in an arc shape, and is connected to the tip of the umbrella edge.

  The length of the umbrella bone described above is equal to or longer than the length of the umbrella surface, or the length of the umbrella surface from the umbrella bone and the tip of the tip, and the length of the umbrella surface from the umbrella bone and joint parts is the length of the umbrella surface. More than that.

In the umbrella bone structure described above, an auxiliary umbrella bone may be provided around the umbrella bone, and the auxiliary umbrella bone is distributed symmetrically with the reference line as an axis.
The auxiliary umbrella bone may be the same as or different from the umbrella bone structure, and may employ a single independent straight bone or a structure similar to a structure in which a branch is formed at the tail end of the umbrella bone.

Furthermore, for an umbrella bone and an auxiliary umbrella bone of the same length, the distance from the diagonal direction and the closer to the meridian direction or meridian direction of the umbrella surface, the longer the umbrella surface installation length at the corresponding umbrella surface position becomes.
On the other hand, the closer to the diagonal direction and the farther away from the warp direction or the parallel direction of the yarn on the umbrella surface, the shorter the umbrella surface length at the corresponding umbrella surface position.

  The umbrella bone described above is provided with a hinge portion at the center thereof, the hinge portion is a convex shape that is fitted and fixed to the parent bone, and the parent bone is joined to the tail portion via the hinge portion.

As a good example, a hinge part is arranged in each umbrella bone, and the tailbone is joined to the parent bone via the hinge part.
Alternatively, two master bones are connected in parallel through one hinge part, and the other umbrella bone is joined to the hinge part to support the two master bones.

The hinge part described above has a downward inclination angle.
The hinge part is installed to form a downward inclination angle with the parent bone, supports the umbrella surface with the tail part of the umbrella bone facing downward, forms an umbrella shape when the umbrella is opened, and the hinge part further increases the ability to wind .

According to the present invention, the umbrella bone is arranged based on the reference line formed by the meridian and latitude lines of the umbrella surface, whereby the umbrella bone is uniformly distributed by the reference line and supports the umbrella surface in a balanced manner.
After opening the umbrella of the present invention, it has a good umbrella shape and can be accommodated smoothly even when the umbrella is closed, achieving good matching between the single-piece umbrella surface and the umbrella bone of the present invention.

Please refer to FIG. FIG. 2 is a yarn display diagram constituting a single umbrella face.
As shown in the drawing, the detailed structure forms a quadrangular lattice structure on the fabric using a line in which a plurality of parallel lines a and a longitudinal line b arranged in parallel in the vertical direction intersect.
The deformation caused by tension depends on the position of the square. The deformation in the diagonal c direction is relatively large, and the deformation in the latitude a and meridian b directions is relatively small.
Thereby, umbrella bones of different angles surrounding the latitude line a or the meridian line b form support for the single-piece umbrella surface. The single-sided umbrella surface differs in deformation corresponding to the angular position.

Also, the deformation of the fabric reacts with the umbrella bone. The same applies to the degree of arc curvature and deformation formed by the umbrella bone.
Therefore, in order to prevent the deformation of the umbrella bone and to form an effective umbrella shape with respect to the single umbrella surface, it is necessary to have a regular arrangement with respect to the umbrella bone.

FIG. 3 shows a first embodiment of the present invention. The single umbrella surface 1 is quadrangular and centered on the middle rod 3, and the diagonal line c of the single umbrella surface 1 is the reference line.
Four master bones 2 are arranged along the reference line, and a tip 4 is installed at the end of the master bone 2.
The tip 4 is fixed to the one-piece umbrella surface 1, and the four main bones 2 are installed at the same length and joined to the upper scissors of the middle rod 3.

Thereby, the umbrella shown in FIG. 4 is formed.
When the umbrella is opened, the plurality of main bones 2 open the umbrella surface 1 to form an arcuate umbrella shape. In addition, a rectangular umbrella surface is formed, and any of the existing structures can be adopted for the rib 7, the upper skull 5, the lower skull 6, and the handle 8.

FIG. 5 is a display diagram of the second embodiment of the present invention, in which the center bar 13 is the center and the diagonal line c of the single umbrella surface 11 is the reference line.
The main bone 12 is set along this reference line, and the end of each main bone 12 passes through the hinge portion 17 and is branched as two tailbones 15 and 16.
The coccyx 15 and 16 have the same length, form an arc shape, extend outward, and are inserted into the tip 14 of the single umbrella surface 11.

At this time, the angle formed by the two adjacent tips 14 is 45 degrees, and a regular octagonal single-piece umbrella surface can be formed.
The coccyx is distributed symmetrically, so that the force received by each part of the single umbrella surface 11 is uniform, and the umbrella can be opened smoothly.

Furthermore, in order to strengthen the support with respect to the single-piece | unit umbrella surface 21, an auxiliary umbrella bone can be increased and a support structure can be strengthened.
FIG. 6 shows a third embodiment of the present invention. It consists of a single umbrella surface 21, a main bone 22, a center rod 23, a tip 24, a tailbone 25, 26, and a hinge portion 28, and the structure thereof matches the method shown in FIG.
However, an auxiliary umbrella bone 27 is added between the middle bar 23 and the tip 24. After opening the umbrella, the auxiliary umbrella bone 27 forms an arc shape and is connected to the corresponding tip 24.
This is located between the main bones 22 to assist the opening of the single umbrella surface 21 and to support the single umbrella surface 21 more firmly.

Please refer to FIG. After passing through the hinge portion 38, the main bone 32 branches as at least three tailbones and supports the single umbrella surface 31. This is the fourth embodiment of the present invention.
The center bar 33 is the center, the diagonal line c of the single umbrella surface 31 is the reference line, and the main bone 32 is installed along this reference line.
A hinge portion 38 is disposed at the end of the master bone 32, and after passing through the hinge portion 38, the three tailbones 35, 36, and 37 extend outward.
The outer ends of the tailbones 35, 36, and 37 are respectively inserted into the tips 34, and the tailbones 35, 36, and 37 are arranged at the same length.

  Among them, the tailbone 36 is located on the reference line like the master bone 32, the tailbone 35 and the tailbone 37 are opened outwardly and form an arc shape, and the tailbones 35, 36, 37 and the master bone 32 are one set at a time. Support for the umbrella surface 31 is formed.

In some implementations described above, the master bone is usually placed on the baseline, but this is not representative of the master bone being placed on the baseline in all implementations; in other implementations, The master bone can be arranged so as to surround the reference line, and the master bone can be arranged symmetrically with the reference line as an axis or a center line.
As a result, the force received by the main bone is equalized, and the single umbrella surface is held in an umbrella shape. Also, after folding the umbrella, the parent bone does not deform and it can be folded smoothly.

FIG. 8 shows a fifth embodiment of the present invention. This is because the main bone 42 is arranged differently from the system shown in FIG. 5, and the diagonal line c centering on the center rod 43 is set as the axis, and is installed symmetrically on both sides of the diagonal line c.
Further, the angle between the main bone 42 and the diagonal line c in the vicinity thereof is 15 degrees (and can be larger or smaller than 15 degrees).
Such a system in which the main bone 42 is provided symmetrically with respect to the diagonal line c can support the single-piece umbrella surface 41 sufficiently stably and firmly. A beautiful umbrella shape can be formed when the umbrella is opened.

The implementation method of the hinge portion 47 in the implementation method is the same as that of FIG. 5, the hinge portion 47 is provided at the end of the parent bone 42, and the hinge portion 47 is branched into two tailbones 45 and 46.
The tip 44 is also fixed to the one-piece umbrella surface 41, and the tailbones 45 and 46 are inserted into the tip 44.

At this time, the arc angle formed by the two tailbones 45 and 46 connected to one parent bone 42 is not so large, and the angle formed by the tailbones 45 and 46 is generally about 15 degrees.
The tailbones 45 and 46 are arranged at equal intervals.

See FIG. This is the sixth embodiment of the present invention. The first main bone 52 and the second main bone 55 are arranged with the diagonal line c, the parallel line a, and the meridian line b as reference lines, and are connected to the middle bar 53 through the upper crossbones.
A first hinge portion 56 is provided at the outer end of the first master bone 52 arranged on the diagonal line c with the middle rod 53 as the center.
The first tailbones 521 and 522 distributed in an arc shape are branched through the first hinge portion 56. The first coccyx 521 and 522 have the same length.

A second hinge portion 57 is provided at the outer end of the second master bone 55 centered on the middle bar 53 with the latitude line a or the meridian b as a reference line, and the second coccyx 551 is provided via the second hinge portion 57. , 552 are connected.
The second coccyx 551 and 552 have the same length.

  In order to maintain the umbrella shape when the single umbrella surface 51 is opened and to ensure that the first master bone 52, the second master bone 55, the first tail bones 521 and 522, and the second tail bones 551 and 552 are not deformed, The length of one tailbone 521, 522 is longer than that of the second tailbone 551, 552, and has a support action in which the parent bone and the tailbone are balanced.

  Further, the outer ends of the first tailbones 521 and 522 and the second tailbones 551 and 552 are all inserted into the tip 54, and the tip 54 is fixed to the edge of the single umbrella surface 51.

Such an arrangement of the main bone and coccyx provides an improvement against inconsistent deformation when receiving force at the latitude line a, meridian b, diagonal c and other angles of the single umbrella surface.
Even when the single-piece umbrella surface is greatly deformed with this master bone, it has a sufficient expansion and contraction space and does not deform when the single-piece umbrella surface is opened or closed.
When the main bone has a single umbrella surface arrangement in which the amount of deformation of the thread is small, the main bone supports the single umbrella surface when the umbrella is opened, and the reaction force against the main bone of the single umbrella surface causes the parent bone to be deformed.
Since the receiving force between each parent bone is unbalanced, the supporting force is also unbalanced and it is difficult to form an effective umbrella shape, and since the deformation of the parent bone is not constant after closing the umbrella, some parent bones protrude, It is difficult to accommodate the main bone and the single umbrella.

Thereby, the ideal implementation method when using such a main bone for a single-sided umbrella surface of the same length is as follows.
The main bone close to the diagonal line c needs to be longer than the length of the single-piece umbrella surface at the position where the main bone is located, and thus has an umbrella shape.
Furthermore, the master bone close to the diagonal line c needs to be longer than the master bone near the latitude line a and the meridian b.
The main bone installed in the direction of the latitude line a and the meridian b from the diagonal line has a shorter length of the parent bone as the distance from the latitude line a and the meridian b approaches, and the length of the parent bone is the length of the single umbrella surface where the parent bone is located. Equal to or greater than
The length of the main bone on the latitude line a and the meridian b is not shorter than the length of the single umbrella surface of the latitude line a and the meridian b, but is shorter than the length of the main bone approaching the diagonal c.

For master bones of the same shape length, the single umbrella surface close to the diagonal line must be shorter than the single umbrella surface close to the meridian and latitude lines, and more than the master bone close to the diagonal line Must be short.
This holds the umbrella shape. The single umbrella surface close to the meridian and latitude lines must be equal to or shorter than the length of the main bone, but longer than the single umbrella surface close to the diagonal.

For the same reason, in the seventh embodiment shown in FIG. 10, the length distribution method is adopted as it is for the arrangement of the master bone.
The structure of the single umbrella surface 61, the main bone 62, the center rod 63, the tip 64, the tailbones 621 and 622, and the hinge portion 65 is the same as the method of FIG. 5, and the angle between the tailbones 621 and 622 is as shown in FIG. It becomes smaller than the structure method shown in
Thus, the auxiliary umbrella bone 66 is arranged in the secured space.

The auxiliary umbrella bone 66 is joined to the middle rod 63 through the upper wheel, and the outer end of the auxiliary umbrella bone 66 is inserted into the tip 64.
Two auxiliary umbrella bones 66 are provided between the main bones 62 arranged with the diagonal line c as a reference line.
An opposing arc shape is formed and extended and inserted into the tip 64.
In addition, the gap between the main bones 62 is compensated, and the single umbrella surface 61 is opened.

  The tailbones 621 and 622 are arranged at the same length, but the length of the auxiliary umbrella bone 66 is shorter than the total length of the tailbone and the parent bone. This creates uniform support and prevents deformation of the parent bone.

FIG. 11 shows an eighth embodiment of the present invention.
The main bone is arranged with the diagonal line c, the latitude line a, and the meridian line b centered on the middle bar as the reference line.
Next, the coccyx is arranged at the outer end of the parent bone, and the lengths of the parent bone and the coccyx are not uniform depending on the arrangement position.

The first master bone 72 is arranged with the diagonal line c as a reference line, and the first hinge portion 75 is arranged at the end of the first master bone 72. Via the first hinge portion 75, the first coccyx 721, 722, 723 that branches in a trifurcated manner is arranged.
The second master bone 76 is arranged with the latitude line a and the meridian b as reference lines, and the second hinge portion 77 is at the end of the second master bone 76. Via the second hinge portion 77, second coccyges 761, 762, and 763 that branch into a trident are arranged.
The first tailbones 721 and 723 have the same length, and the second tailbones 761 and 763 have the same length. However, the first coccyx 721, 723 must be longer than the second coccyx 761, 763, and the first coccyx 722 is located just diagonally.
Therefore, the length of the first coccyx 722 is longer than the first coccyx 721 and 723 and the second coccyx 761 and 763.

Since the second coccyx 762 is located on the latitude line a and the meridian b, the length of the second coccyx 762 is shorter than the first coccyx 721 and 723 and the second coccyx 761 and 763.
In this way, uniform support is formed for the single umbrella surface 71, an umbrella shape is formed when the single umbrella surface 71 is opened, and when the umbrella is closed, the master bone and tailbone (first master bone) , Including the second parent bone, the first coccyx, and the second coccyx) are not deformed.

  The ends of the first coccyx 721, 722, 723 and the second coccyx 761, 762, 763 are inserted into the tip 74 fixed to the single umbrella surface 71 to form a stable joint structure.

As can be seen from the arrangement of the main bones in the sixth to eighth embodiments, the length of the main bone can be adjusted based on the actual situation. Similarly, the length of the single-piece umbrella surface can also be adjusted based on the actual situation. .
For example, in order to process a single umbrella face having a special shape, the lengths of the single umbrella face and the main bone are adjusted.

The diagonal c can be used as a reference line, and the master bone can be arranged symmetrically on both sides of the reference line. Similarly, the meridian or parallel can be used as the reference line, and the master bone can be arranged symmetrically on both sides of the meridian or parallel.
FIG. 12 shows a ninth embodiment of the present invention. In other words, this is an implementation method in which the parallels a and meridians b are used as reference lines, and the parent bones are symmetrically arranged on both sides.

In FIG. 12, the latitude line is a, the meridian is b, and the main bone 82 is joined to the middle rod 83 through the upper wheel.
The four parent bones form an arc shape that curves inward and are distributed on both sides of the latitude line a, and the four parent bones 82 curve inward to form an arc shape and are distributed on both sides of the meridian b.
Further, the end of the main bone 82 is inserted into the tip 84, and the tip 84 is uniformly arranged on the edge of the single umbrella surface 81, thereby forming a stable joint structure.
As a result, a stable and stable support for the single umbrella surface 81 can be formed.

See FIG. This is a display diagram of the main bone and the single umbrella surface of the tenth embodiment of the present invention.
The main bone 92 is evenly distributed so as to surround the middle rod 93, and the main bone 92 is also connected to the tail bones 95 and 96 extended outward through the hinge portion 94.
The tailbones 95, 96 form an arc shape and extend outward, and the outermost ends of the tailbones 95, 96 are fixed to the edge of the single umbrella surface 91. In this way, the single umbrella surface 91 is supported.

  Eight main bones 92 are provided, all of which are equally arranged around the middle rod 93. Further, these parent bones 92 are not placed on the axes a, b, or c, and these axes are arranged symmetrically.

  In summary, each parent bone is arranged on the reference line with the diagonal line of the single umbrella surface centered on the center rod, or the meridian and latitude lines thereof as the reference line. Alternatively, it is distributed symmetrically, and the opening and closing of the umbrella can be performed smoothly by receiving the acting force and supporting force in which the main bone and the single-piece umbrella surface are balanced.

  The above description is only an example of the present invention, and does not limit the scope of the present invention. Any equivalent changes and modifications that can be made based on the scope of the claims of the present invention are all described in the present invention.
