Abstract
Abstract A reflection type flow-flashing light, used for issuing a warning signal, which is mounted on the roof of an emergency vehicle, characterized such that rotating lights are installed on the opposite side ends of a unit base, a plurality of reflecting plates against which a flood from the rotating lights reflects in both the forward and backward directions are spaced adequately between the opposite side sections of the rotating lights with the given inclining angles of the reflecting plate, which are different from each other, formed in relation to the rotating lights, respectively and at the same time spaces through which the flood therefrom pass are formed between the above-mentioned reflecting plates.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
197 words
A reflection type flow-flashing light comprising: an elongated base having a forward and rearward direction; at least one rotating light operatively positioned at one end of said elongated base; a plurality of reflecting plates being spaced relative to each other and being mounted on said elongated base adjacent to said rotating light, each of said reflecting plates being disposed at a predetermined position for enabling light emitted from said rotating light to pass therebetween to impinge upon each of said reflecting plates while reflecting said light in a direction both forward and rearward; said elongated base includes a first end and a second end, said at least one rotating light being positioned adjacent to said first end and further including a second rotating light operatively positioned adjacent to said second end and a plurality of reflecting plates being spaced relative to each other and being mounted on said elongated base adjacent to said second rotating light, each of said reflecting plates being disposed at a predetermined position for enabling light emitted from said rotating light to pass therebetween to impinge upon each of said reflecting plates while reflecting said light in a direction both forward and rearward.
Claim 2
Dependent Claim
197 words
A reflection type flow-flashing light comprising: an elongated base having a forward and rearward direction; at least one rotating light operatively positioned at one end of said elongated base; a plurality of reflecting plates being spaced relative to each other and being mounted on said elongated base adjacent to said rotating light, each of said reflecting plates being disposed at a predetermined position for enabling light emitted from said rotating light to pass therebetween to impinge upon each of said reflecting plates while reflecting said light in a direction both forward and rearward; said elongated base includes a first end and a second end, said at least one rotating light being positioned adjacent to said first end and further including a second rotating light operatively positioned adjacent to said second end and a plurality of reflecting plates being spaced relative to each other and being mounted on said elongated base adjacent to said second rotating light, each of said reflecting plates being disposed at a predetermined position for enabling light emitted from said rotating light to pass therebetween to impinge upon each of said reflecting plates while reflecting said light in a direction both forward and rearward.
Claim 3
Dependent Claim
173 words
A reflection type flow-flashing light comprising: an elongated base having a forward and rearward direction; at least one rotating light operatively positioned at one end of said elongated base; a plurality of reflecting plates being spaced relative to each other and being mounted on said elongated base adjacent to said rotating light, each of said reflecting plates being disposed at a predetermined position for enabling light emitted from said rotating light to pass therebetween to impinge upon each of said reflecting plates while reflecting said light in a direction both forward and rearward; said plurality of reflecting plates includes a first, second and third group of plates, the first and second groups each containing two reflecting plates positioned at an angle relative to said base for reflecting said light in a direction both forward and rearward and being spaced relative to each other for permitting light to pass therebetween, and said third group containing a single reflecting plate bent at an angle for reflecting said light in both a forward and rearward direction.
Claim 4
Dependent Claim
173 words
A reflection type flow-flashing light comprising: an elongated base having a forward and rearward direction; at least one rotating light operatively positioned at one end of said elongated base; a plurality of reflecting plates being spaced relative to each other and being mounted on said elongated base adjacent to said rotating light, each of said reflecting plates being disposed at a predetermined position for enabling light emitted from said rotating light to pass therebetween to impinge upon each of said reflecting plates while reflecting said light in a direction both forward and rearward; said plurality of reflecting plates includes a first, second and third group of plates, the first and second groups each containing two reflecting plates positioned at an angle relative to said base for reflecting said light in a direction both forward and rearward and being spaced relative to each other for permitting light to pass therebetween, and said third group containing a single reflecting plate bent at an angle for reflecting said light in both a forward and rearward direction.
Claim 5
Dependent Claim
90 words
A reflection type flow-flashing light according to claim 1, wherein said plurality of reflecting plates includes a first, second and third group of plates, the first and second groups each containing two reflecting plates positioned at an angle relative to said base for reflecting said light in a direction both forward and rearward and being spaced relative to each other for permitting light to pass therebetween, and said third group containing a single reflecting plate bent at an angle for reflecting said light in both a forward and rearward direction.
Claim 6
Dependent Claim
21 words
A reflection type flow-flashing light according to claim 1, wherein said plurality of reflecting plates reflects light in an orthogonal direction.
Claim 7
Dependent Claim
21 words
A reflection type flow-flashing light according to claim 2, wherein said plurality of reflecting plates reflects light in an orthogonal direction.
Claim 8
Dependent Claim
20 words
A reflection type flow-flashing light according to claim 1, and further including a siren for emitting a loud warning sound.
Claim 9
Dependent Claim
21 words
A reflection type flow-flashing light according to claim 1, and further including a transparent cover unit for mounting on said base.
