ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a safety cap. More particularly, the present invention relates to a safety cap which can protect a head of a user against a bumping force.
A conventional safety cap has a hard outer casing which is made of acrylic material and an inner layer which is made of expandable polystyrene. When the conventional safety cap is bumped, the acrylic hard outer casing cannot absorb a bumping force. The expandable polystyrene inner layer cannot absorb the bumping force effectively. Because the polystyrene inner layer separates a head of a user from the hard outer casing, the user will feel comfortable while wearing the polystyrene inner layer.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a safety cap which has a PVC transparent layer to be deformed while bumping.
Another object of the present invention is to provide a safety cap which has an EVA foamed layer to be deformed elastically and to absorb shock while bumping.
Another object of the present invention is to provide a safety cap which has a bump-resisting rigid casing made of nylon material to protect the safety cap from cracking.
Another object of the present invention is to provide a safety cap which has a plurality of trigonal pyramid reflection devices in order to reflect lights.
Another object of the present invention is to provide a safety cap which has a plurality of fluorescence films disposed on surfaces of trigonal pyramid reflection devices in order to illuminate fluorescent lights.
Another object of the present invention is to provide a safety cap which has a plurality of light-emitting diodes disposed on a rear portion of a bump-resisting rigid casing in order to produce warning lights to warn passengers and vehicle drivers.
Another object of the present invention is to provide a safety cap which has a plurality of air inlets, a plurality of channels and a plurality of vent holes in order to ventilate the safety cap by opening a plurality of door plates.
Another object of the present invention is to provide a safety cap which has an oblong hole to receive a microphone and a through hole to receive an earphone in order to communicate with a mobile phone.
In accordance with a first preferred embodiment of the present invention, a safety cap comprises a bump-resisting rigid casing, a plurality of trigonal pyramid reflection devices disposed on an outer surface of the bump-resisting rigid casing, a transparent layer enclosing the outer surface of the bump-resisting rigid casing and the trigonal pyramid reflection devices, and a foamed layer disposed in the bump-resisting rigid casing. A plurality of air inlets are formed on a top front portion of the bump-resisting rigid casing. A plurality of channels are formed on a top portion of the bump-resisting rigid casing. A plurality of vent holes are formed on the top portion of the bump-resisting rigid casing and communicated with the channels. A plurality of hollow frames are inserted in the air inlets. A plurality of door plates covers the air inlets. Each of the door plates is inserted in the respective hollow frame. The bump-resisting rigid casing is made of nylon materials. The transparent layer is made of polyvinyl chloride materials. The foamed layer is made of ethylene/vinyl acetate materials. A fluorescence film is applied on each trigonal pyramid reflection devices.

A fluorescence film is applied on each trigonal pyramid reflection devices. A plurality of round holes are formed on a rear portion of the bump-resisting rigid casing. A plurality of light-emitting diodes are inserted in the round holes. A through hole is formed on a side of the bump-resisting rigid casing. An earphone is inserted in the through hole. An oblong hole is formed on a front lower portion of the bump-resisting rigid casing. A microphone is inserted in the oblong hole. A battery chamber is formed on the bump-resisting rigid casing. A lithium
ickel battery is disposed in the battery chamber. A cover covers the battery chamber. A switch is disposed on the cover.
