In order to escape death-or a fatal .wound caused b y cidents, various kinds of helmets are used, as .ajmeans for protecting the head against impact at the time of accidents, by

those who'drive a motorcycle orthe like, why those,-who are engaged in dangerous work,such as coal miners, stevedores,

etc. i I

There is no doubtthatsuchihelmets can be of help in preventing an injury at the time of accidents. However, it must be noted that conventional helmets function only as a protec tive headgear at-the time when the user meets withan accident, and they are incapable of preventing accidents, such as atraffic accident, from occurring. 1

It is absolutely-necessary that all accidents be prevented in order to completely prevent an injury. The present invention aims to prevent accidents, especially a night traffic accident,

from occurring by providing a newand useful helmet having reflectors, in view of the fact that accidents, particularly a night traflic accident, show an increasing tendency lately.

lt is therefore the principal object of the present invention 7 to provide a helmet with reflectors, capable of protecting those who drive a motorcycle or the like from a night traffic accident, said reflectors being constructed so as to reflect incident rays of light in the direction of the light source.

Another object of the invention is to provide a helmet with reflectors, capable of making the users, who 'work together in the dark, such as in a tunnel, etc., able to find their locations relative to each other and thereby enable them to work in safety.

A further object of the invention .is to provide a belt having a number of reflectors which reflect incident rays of light in the direction from which they have come, said 'belt being adapted to be attached to any desired headgear.

Further objects and additional. advantages of the invention will become apparent from the following detailed description and annexed drawings in which:

FIG. 7 is a partly broken-away side view of a.helmet to which the combination of the reflectors and the base members, shown in FIGS. 5 and 6 are attached; and

FIG. 8 is a diagram illustrating how an incident ray of light is reflected by elements of a reflector.

In FIGS. 1 to 8 like portions or parts are designated with like numerals.

Referring to FIG. I, there is shown one embodiment of the present invention, comprising a conventional helmet 10, a belt 11 encircling the lower peripheral portion thercof,-and a plurality of reflectorsIZ attached to the belt. The belt I I is made of flexible material, such assynthetic rubber and is provided with a plurality ofopenings 13 which are spacedly formed therein for receiving said reflectors. Each reflector 12 is secured to the belt 11in the manner depicted in FIG. 3.

. The belt 11 is formed on its inner surface with a longitudinal recess 14 which lengthwise extends along the middle area or portion thereof. The openings I3 for receiving the reflectors 12 are formed in said middle area.

On the outer surface of the belt 11 are formed a plurality of longitudinal convex lines 15 for decorative purpose, each of which terminates at the side edges of the openings 13.

The belt 11 may be either a strip of suitable length or a circular strip as shown in FIG. 2. In the latter case, the diameter must be properly predetermined so that the belt may be snugly mounted on the periphery of the helmet. However, the belt 11 may, of course, have a certain tolerance as long as it has flexibility. It is preferable that the belt 11 carrying the reflectors 12 be provided with a U-shaped groove 17 formed by inwardly and upwardly turning the lower edge 16 of the belt 11 so that when the belt is attached to the lower peripheral portion 18 of the helmet 10, the U-shaped groove 17 may fit the edge 19 of the helmet to thereby protect the edge and at the same time to enable the belt to be securely attached to the helmet. In case the belt 11 is made in the form of a strip, it should be securely fastened at its ends with a suitable fastener when attached to the helmet.

Each reflector I2 is formed of a transparent synthetic resin, such as acrylic resin and is provided with a lens portion 20 and relatively thin flangelike portions 21, said lens portion being of convex shape and having its rear surface formed with a number of reflector elements 22, FIG/8, adapted to reflect incident rays of light entering through the lens portion 20 from any light source, such as the car headlight. In the illustrated embodiments, the reflector elements 22 are of the so-called diamond cut type and adapted to reflect the incident rays substantially in the direction from which they have come. As illustrated in FIG. 8, when the incident ray A entering the lens portion 20 of the reflector 12 from the light source, such as, for example, a car headlight 25, strikes a surface of an element 22 at B, it is bounced from the surface and strikes a surface of another element 22 at C, and is then reflected substantially in the direction of the light source 25 and reaches, as a reflected ray D, a man's eye 26, such as the driver of a car in the vicinity of the light source.

To attach a reflector 12 to the belt II, its lens portion 20 is inserted in an opening I3 of the belt from the inside thereof so that flangelike portions 21 come into engagement with said longitudinal recess 14 of the belt to thereby prevent the reflector 12 from coming off.

Illustrated in FIG. 5 is a combination of a circular reflector I2 and its base member 23, said reflector being attached to a circular base member 23 to be mounted on any desired outer portion of the helmet. The reflector 12 has formed on its rear surface a number of reflector elements as in the reflector 12 shown in FIG. 3. The base member 23 carrying the reflector has its rear surface coated with suitable sticking material so that it may be attached to any desired outer portion of a helmet 10' in the manner depicted in FIG. 7. Indicated by numeral 24 is a removable protecting film, such as siliconpaper which is normally attached to the rear surface of the base member 23 where said sticking material is coated, and which is stripped off before the base member is attached to a desired outer portion of the helmet I0.

Illustrated in FIG. 6 is another combination of a base member 23' and a reflector 12". The base member 23' is attached, as shown in FIG. 7, to any desired outer portion of the helmet 10 with suitable binding agent 24'. It is without saying that in these instances, the belt II does not need to be employed for carrying the reflectors I2, 12".

it v 3 wear the 1 6} 1 d, they carrbe readily found by other persons whodri ve car, truck, etc, and a traffic accident may be preventedfromoccurring. Likewise, if those who are en-' gaged in dangerous work, siich asco'al miners,,we ar a miners helmet with such reflectorsin th'e dark, they will be able to easily find their locations relative to each other and mining operation will be carried on in safety.

It should be noted that the belt 11 carrying the reflectors [2 may be attached to other headgear, if desired.
