Abstract

The utility model relates to a folding sun hat, which is the structural improvement of the sun hat. The utility model solves the problem of the existing sun hat occupying too much space when not used. The utility model is mainly formed by a hat brim and a hat body which are connected when the hat brim and the hat body have same curvature. Without the reaction of the external force, the hat brim and the hat body which keep the same curvature are both trended to a flat state and are closed with each other. The integration of the folding sun hat is of a plane flaky shape, and the occupying space is quite small. The utility model achieves the purposes of saving space and portability in the process of storage and transportation.

Description

Folding sun hat

The utility model relates to the improvement of sunbonnet structure.

The global shape of the sunbonnet that is made of the brim of a hat, cap body two parts in the prior art is a malleable not, because usually when making this sunbonnet, be that the brim of a hat that is in flattened state is connected with the cap body that is in case of bending, this has just determined the cap body may be in flattened state never, and can only be further crooked when the brim of a hat is crooked.When the brim of a hat is open and flat, the cap body remains crooked.The brim of a hat, both curvature of cap body are inconsistent.Above situation is well-known.Needn't cited paper.

The purpose of this utility model is: solve the take up space problem of excessive and difficult harvesting of existing sunbonnet when not using, provide a kind of and be easy to carry, can be folded into the sunbonnet of flat thin sheet.

The utility model mainly is made of cap body, the brim of a hat two parts.Connect when both are in same curvature at cap body, the brim of a hat, suitable arc is adopted in the junction, and the geometric shape of this arc is consistent with the arc of the brim of a hat trailing edge.

When cap was not subjected to any external force, because the elasticity that had of hatting itself, cap body, the brim of a hat were tending towards flattened state simultaneously and also press close to mutually and keep identical curvature.Whole near the flat thin sheet.Wherein one (normally cap bodies) are by external force when crooked when the brim of a hat, cap body, and it is crooked that another person also is tending towards under the stress effect, (both keep similar curvature usually).When said in front BENDING PROCESS begins, begin to occur angle between the brim of a hat, the cap body, and along with the aggravation of bending, this angle is increasing.When the cap body is curved to can match with people's forehead the time, mitre joint between the two is bordering on the angle between the sunbonnet the brim of a hat and cap body in the prior art.

When cap is taken, when external force disappeared, the elasticity of hatting itself made the brim of a hat, cap body be tending towards open and flat simultaneously and presses close to mutually, and angle between the two is tending towards zero degree.

As long as all parts of the determined camber line of cap body and the brim of a hat junction all be in same plane then no matter the radius of this camber line how to change.(this variation will take place at the cap body, when the brim of a hat is bent) cap body, both curvature of the brim of a hat always identical (or similar).

The advantage that the utility model compared with prior art has is: can be folded into the flat thin sheet when non-working condition, the space that occupies is minimum, and not fragile, reduces carrying cost and loss.

Description of drawings: 1. figure is cap body fundamental form.2. figure is the brim of a hat basic model (thick line is a brim of a hat trailing edge).Outside drawing when 3. figure is non-working condition.Three-view diagram when 4. figure is user mode.

Be optimum implementation below:

With flexible elastic sheet material cutting one-tenth figure 1., scheme 2. shape, in order to be fit to most Chinese people's head size as far as possible, radius during the brim of a hat trailing edge camber line flattened state can be defined as about 13 centimetres, and the chord length of camber line can be defined as about 22 centimetres, and the size randomness of other parts is bigger.

All be in flattened state (curvature is identical) and when being close to mutually, the brim of a hat trailing edge be connected with the cap body along cap dotted line on one's body at cap body, the brim of a hat, concrete connected mode can adopt first at the brim of a hat trailing edge bag one selvedge, again with the method for this selvedge and the stitching of cap body.

Cap body two ends are connected (as figure 3.) with the telescopic elastic material.

Obviously, may make many improvement and variation according to top narration, for example: in the surface punching of cap body to strengthen gas permeability, at the surface recombination fabric to increase the variation of aesthetic feeling and profile, size ...What therefore can fully understand and infer be: the utility model can be implemented with the alternate manner that is different from the mode of clearly narrating.

Claims

The sunbonnet a kind of mainly by the brim of a hat, that the cap body constitutes is characterized in that the cap body has the curvature of identical (similar) usually with the brim of a hat.The brim of a hat trailing edge is the arc of indent.The brim of a hat trailing edge connects part with the cap body and has identical geometric shape at the arc of determined arc of cap and the brim of a hat trailing edge on one's body.The cap body the brim of a hat is made with flexible elastic sheet material.
