What is “RIKEN spindle” that wraps a luminous body around a wire rope

I. Basic Structure

Japanese Patent Application No. 2017-019569 "Rotary moving body and rope material connecting tool using rotary moving
body, power generation device, visual guidance device, device for removing a snow bale, and method for manufacturing ropematerial"

Wire ropes are manufactured by bundling several wires and twisting them in a spiral. A groove is formed between wire ropes, and this shape can be
regarded as a bolt with a long pitch. On the other hand, rotary moving body that corresponds to nut is the “RIKEN spindle”. If this rotating body is
not rotated, it will not move when pushed or pulled.

About "Linear high brightness light emitter"
Structure and principle of light emitter
It has a two-layer structure consisting of an acrylic resin core(inside) and a fluorine resin cladding (outside). The light incident
from light emitter end is reflected between core and cladding,and part of the light is emitted from light emission part side
while reaching the end, we will obtain linear uniform highbrightness light emission along the shape.

Acrylic resin① Create wire rope cross section② Make wire rope as male shapeand make a cross section of its
female shape

II. Luminescent body winding structure③ Create a structure in which ② ismoulded in same twisting direction andpitch as the wire rope

Visibility Test In Wind Tunnel Test

We conducted wind tunnel experiment with modelsnow (active white soil) using a road model that wasreduced to a range that can be verified by wind tunnel
equipment, in order to verify the visibility seen from theeyes of the traveling vehicle. In the experiment, a roadand a wire rope type guard fence and a green lightemitter are reproduced at a scale of 1/8, and running on
the road with a small electric camera equipped with asmall video camera causes snowfall to occur during
winter night. We evaluated the visibility in theenvironment and in the direction of blowing snow
(headwind, crosswind) 。

Experiment was conducted with model snow (activated white soil) in which three light emitters (φ 3.5 mm) were wound around a full size
wire rope (φ 18 mm, L = 4.0 m), a wind tunnel, in order to verify the visibility in blowing snow. In the experiment, assuming daytime andnight time of winter and night time, that luminous body emitted green light, then evaluate the visibility in blowing snow presence andabsence environment.
Result: Even at the time of blowing snow during daytime and night, there was a reduction effect of ambient illumination and light diffusion
effect, and we know that the luminous body could be confirmed regardless of the occurrence of blowing.

During Snow Storm

We conducted wind tunnel experiments withmodel snow (active white soil) with one luminous
body (Φ 3.5 mm) wound around a full-sized wirerope (Φ 18 mm, L = 4.0 m), in order to verify thevisibility due to luminescent color differences. In
the experiment, the visibility of the light emittersemitted by the LEDs of three colors (green, blueand red) was evaluated under the conditions
assuming normal season and winter night time.
Result: We know that green light emission is themost effective for vision.

During Snow Storm

GreenWe conducted wind tunnel experiment with model snow (active clay) with three luminous bodies (φ 3.5 mm) woundaround a full-size wire rope (φ 18 mm, L = 1.0 m), in order to verify the relationship between snowfall on the wire ropeand visibility at the time of snowstorm. In the experiment, we assumed winter daytime and night time, and we evaluatedgreen light emitting body at the time of the occurrence of the snowstorm due to the crosswind.
Result: A lot of adhesion of model snow was seen in the stranding groove of the wire rope, but the part where theilluminant was wound was in a convex state and it was difficult to adhere the coating layer. It is evaluated that the effectof preventing light emission is small by transmitting light.

Collision ExperimentFirst
This product has LED control board, battery, and solar module built-in a rubber cap, and this rubber cap is attached tocolumn top. Rubber cap should not be scattered in a vehicle collision, so it is connected with a "RIKEN spindle" and"rubber wire", which is used in emitting body winding. We conducted a collision experiment in our parking lot, in orderto make sure that this rubber cap, light emitting part and "RIKEN spindle" did not scatter in vehicle collision. Since therubber wire length may affect rubber cap behaviour at vehicle collision, experiment was conducted with changing therubber wire length.

Rubber wire length 30 cm

Rubber wire length 20 cm

Solar Cell Module Impact Test
Impact Test With Steel Ball Drop
Test conditions・ Steel ball weight: 1.7 kg, steel ball diameter 75 cm
・ Falling height: 1.0 m
・ Steel ball speed at impact: 4.427 m / s (15.937 km / h) Impact force: 16.66 J

Rubber wire length 10 cm

Experiment result : succeed① Confirmed that rubber cap does not come off from spindle and does not fly away.
② Confirm that there is no damage in rubber part.
③ Because light emitting part is spirally wound, confirmed that it is compressed and solidified like aspring and does not scatter as it is pushed by the “RIKEN spindle”.

SecondWe used dummy solar module in our first collision experiment, so we conducted second collision experiment on a massproduced solar module. The solar module has a sealing material (EVA) sanded with an acrylic plate. The sealingmaterial is flexible and has an adhesive role, so it is hard to break even if it receives an impact, but it was confirmedthat it did not scatter. As a comparison target, an experiment was simultaneously conducted with an acrylic single plate.
