Automatic opening and closing umbrella using 100% shading fabric.
It is unisex and can be used as a umbrella.
"HEAT BLOCK" has a two-layer structure in which a light shielding film is bonded to the back of the fabric. This two-layer structure achieves 100% shading.
As long as the fabric is not torn, its shading effect is semipermanent.
Regarding the light shielding performance, 100% light shielding has been confirmed by the third party inspection organization's inspection of the light shielding property.
The inspection method is a device that evaluates the light shielding property of curtains, etc., and is implemented in accordance with JIS-L-1055 A method (equivalent to 100,000lux illuminance summer sunlight).
【Notes】Inspection of shading rate is performed only with umbrella fabric. Inspection can not be performed on finished products that have been sewn. There are sewing parts in the finished product, and light may leak from seams and so on.

Sunlight is transmitted by UV protection 91.7% fabric
100% shading fabric does not transmit sunlight
It has been confirmed that UV shielding rate is 99.9% (maximum value) by UV measurement inspection by a third party inspection organization.
The measurement wavelength is 280mm-400mm, using a band pass filter.
The fabric is light and lightly modified by weaving with fine threads.
The thickness of the yarn used in general umbrellas is 75 denier, but the fabric used for "HEAT BLOCK" is 15 denier, the same level as the thinness of the yarn used in stockings.
We reviewed the spring structure built into the shaft of the automatic opening / closing umbrella. We reduced the power to store the shaft by about 45% compared to our company, and now we can operate smoothly even if the power is weak.
<Test method> Testing of the force applied when storing the shaft is conducted at a third party inspection organization. Using a constant-speed extension tester, the maximum load (unit: Newton) was measured when pushing 250 mm from the handle side to the stone side with the automatic retractable umbrella closed and the shaft extended.
Although it is an automatic opening and closing umbrella that is easily broken due to its complicated structure, "SmoothAutomatic" has cleared 500 switching endurance tests. Third-party inspection organizations have demonstrated that they can be used without any problems even after endurance testing with 500 cycles of opening and closing at a rate of 6 times per minute.
It requires less force to extend and contract the shaft than conventional automatic opening and closing umbrellas, so it can be easily operated even by people with weak forces.
The umbrella opens when you press the button built into the handle.
When the button is pressed while the umbrella is open, the umbrella closes. The shaft is not automatically expanded and contracted, but stored manually.
