Abstract
Abstract A switch construction for use on an illuminated article worn by a user which closes a circuit providing current to an illumination source only upon the occurrence of acceleration reacting to motions of the user while at the same time limiting the amount of time the illumination source is operative, and preventing accidental continuous operation of the illumination source while the device is not in use or the body of the wearer is motionless. The switch is not gravity sensitive, and can operate in any position on the body of the wearer.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
138 words
An improved switch construction responsive to the motions of a wearer comprising: a relatively fixed base adapted to be secured to desired portions of the clothing of the wearer in relatively fixed relation thereto; a substantially balanced mass mounted for pivotal movement upon said base about an axis; means for limiting said pivotal movement of said mass in at least a first angular direction; a pair of electrical contact means, at least one of which lies in the path of pivotal movement of said mass in at least one angular direction; and a source of electromotive force and an illumination means connected in series with said contact means; whereby said contact means will be closed to illuminate said illumination means only upon the occurrence of angular acceleration of said balanced mass in said at least one angular direction.
Claim 2
Dependent Claim
138 words
An improved switch construction responsive to the motions of a wearer comprising: a relatively fixed base adapted to be secured to desired portions of the clothing of the wearer in relatively fixed relation thereto; a substantially balanced mass mounted for pivotal movement upon said base about an axis; means for limiting said pivotal movement of said mass in at least a first angular direction; a pair of electrical contact means, at least one of which lies in the path of pivotal movement of said mass in at least one angular direction; and a source of electromotive force and an illumination means connected in series with said contact means; whereby said contact means will be closed to illuminate said illumination means only upon the occurrence of angular acceleration of said balanced mass in said at least one angular direction.
Claim 3
Dependent Claim
81 words
An improved switch construction responsive to the motions of a wearer in accordance with claim 1, further characterized in said base including a pair of aligned trunnions extending upwardly from said base, a shaft carried by said trunnions, said balanced mass being of generally elongate configuration and having a substantially centrally disposed hub engaging said shaft, a pair of oppositely disposed web portions extending radially from said hub, and a pair of enlargements carried by the outer ends of said webs.
Claim 4
Dependent Claim
100 words
An improved switch construction responsive to the motions of a wearer in accordance with claim 2, further characterized in said switch contacts comprising elongated conductive tongues, a free end of one of which is positioned to contact one of said radially extending webs adjacent said hub upon the rotation of said balanced mass to be displaced thereby to cause said one of said contacts to make communication with the other of said contacts, continued displacement thereafter resulting in a sliding mutual contact between said switch contacts to effect a clearing action serving to remove accumulated oxides at points of communication.
Claim 5
Dependent Claim
20 words
The improvement in accordance with claim 1, in which said source of electromotive force forms part of said balanced mass.
Claim 6
Dependent Claim
26 words
The improvement in accordance with claim 1, in which said source of electromotive force forms at least fifty percent of the mass of the balanced mass.
Claim 7
Dependent Claim
20 words
The improvement in accordance with claim 1, further characterized in said illumination means forming a part of said balanced mass.
Claim 8
Dependent Claim
38 words
An improved switch construction responsive to the motions of a wearer in accordance with claim 1, further comprising means for limiting said pivotal movement of said mass in a direction opposite to said at least one angular direction.
Claim 9
Dependent Claim
102 words
An improved electrical switch construction responsive to the motions of a wearer, sensitive only to imparted rotational acceleration comprising: a relatively fixed base adapted to be secured to a moving article, a substantially balanced mass mounted for pivotal movement upon said base, at least one pair of electrical contact means, one of said contact means being disposed in the path of pivotal movement of said mass when displaced in at least one angular direction; and a source of electromotive force and an illumination means coupled to said contact means, said source of electromotive force forming at least part of said balanced mass.
Claim 10
Dependent Claim
102 words
An improved electrical switch construction responsive to the motions of a wearer, sensitive only to imparted rotational acceleration comprising: a relatively fixed base adapted to be secured to a moving article, a substantially balanced mass mounted for pivotal movement upon said base, at least one pair of electrical contact means, one of said contact means being disposed in the path of pivotal movement of said mass when displaced in at least one angular direction; and a source of electromotive force and an illumination means coupled to said contact means, said source of electromotive force forming at least part of said balanced mass.
Claim 11
Dependent Claim
28 words
An improved switch construction responsive to the motions of a wearer in accordance with claim 8, further characterized in said illumination means forming part of said balanced mass.
Claim 12
Dependent Claim
66 words
An improved switch construction responsive to the motions of a wearer in accordance with claim 8, further characterized in said source of electromotive force comprising a pair of elongated dry cells arranged in oppositely extending directions, so that any variation in the position of the center of gravity along the longitudinal axis of individual cells of different manufacture is compensated using an identical pair of cells.
Claim 13
Dependent Claim
62 words
An improved switch construction responsive to the motions of a wearer in accordance with claim 10, in which one pair of battery contacts of the same polarity is fixed in position and made of rigid material, and the other pair of contacts is made of resilient material so that identical cells from different manufacturers with slightly different overall lengths may be used.
Claim 14
Dependent Claim
29 words
An improved switch construction responsive to the motions of a wearer in accordance with claim 10, wherein said pair of elongated dry cells are disposed in a side-by-side relationship.
Claim 15
Dependent Claim
31 words
An improved switch construction responsive to the motions of a wearer in accordance with claims 1 or 8, further comprising means to removably secure said base to an article of clothing.
Claim 16
Dependent Claim
29 words
An improved switch construction responsive to the motions of a wearer in accordance with claims 1 or 8, further comprising a housing, said housing being secured to said base.
Claim 17
Dependent Claim
21 words
An improved switch construction responsive to the motions of a wearer in accordance with claim 14, wherein said housing is translucent.
