Abstract

Abstract An illumination device (7, 23) for a wristwatch (1), having a completely self-contained power source (15) and illuminating lamp (17, 29) which is carried on the watchband (6). A flexible wall (21, 31) permits contact between lamp terminals (20, 35) and battery terminals to close the circuit when the device is manually actuated. An overhanging portion (8, 26) extends beyond the attachment (28) of the band to the wristwatch, so that the lamp (17, 29) may illuminate the face (4) of the wristwatch.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 149 words
In a wristwatch having a case with connection means for attachment of a watchband and containing a timepiece face portion to be illuminated, and a watchband having first and second attachment ends, at least said first end being attached to said connection means, the improvement comprising a self-contained illumination device removably held by said second attachment end of the watchband and having an overhanging portion extending beyond said connection means and carrying a lamp arranged to illuminate said face portion, said illumination device defining a cavity, a battery disposed in said cavity having a pair of battery terminals, a pair of lamp terminals disposed in said cavity connected to said lamp a portion of the wall of said cavity being flexible and adapted to permit contact between at least one of said battery terminals and at least one of said lamp terminals when the illumination device is manually actuated.
Claim 2
Dependent Claim 149 words
In a wristwatch having a case with connection means for attachment of a watchband and containing a timepiece face portion to be illuminated, and a watchband having first and second attachment ends, at least said first end being attached to said connection means, the improvement comprising a self-contained illumination device removably held by said second attachment end of the watchband and having an overhanging portion extending beyond said connection means and carrying a lamp arranged to illuminate said face portion, said illumination device defining a cavity, a battery disposed in said cavity having a pair of battery terminals, a pair of lamp terminals disposed in said cavity connected to said lamp a portion of the wall of said cavity being flexible and adapted to permit contact between at least one of said battery terminals and at least one of said lamp terminals when the illumination device is manually actuated.
Claim 3
Dependent Claim 29 words
The improvement according to claim 1, wherein said lamp terminal is disposed on the flexible wall and spaced from said battery terminal to contact same when the wall moves.
Claim 4
Dependent Claim 51 words
The improvement according to claim 1, wherein said cavity wall is shaped to permit movement of the battery when the illumination device is manually actuated through the flexible wall portion, and wherein said lamp terminal is disposed in the cavity to be contacted by said battery terminal when the battery moves.
Claim 5
Dependent Claim 45 words
The improvement according to claim 1, wherein said second attachment end of the watchband is connected to the connection means, and wherein the means to hold the illumination device on the watchband, comprises a longitudinal passage through the illumination device adapted to receive the watchband.
Claim 6
Dependent Claim 42 words
The improvement according to claim 1, wherein said second attachment end of the watchband is connected by a springbar to lugs disposed on the illumination device and wherein the illumination device is connected by a springbar to lugs disposed on the watchcase.
Claim 7
Dependent Claim 18 words
The improvement according to claim 1, wherein said illumination device includes a removable insert carrying selected graphic material.
Claim 8
Dependent Claim 159 words
In a wristwatch having a case containing a timepiece face portion to be illuminated and a watchband having attachment ends connected at connection means to opposite sides of said case, the improvement comprising a self-contained illumination device including a longitudinal passage adapted to receive one end of the watchband and to slide to a position adjacent to the watchcase, said illumination device having an overhanging portion extending over the watchcase beyond the connection means between the watchband and the watchcase and carrying a lamp arranged to illuminate said face portion, said illumination device defining a cavity containing a battery having a pair of battery terminals, a pair of lamp terminals disposed in the cavity connected to said lamp, a portion of the cavity wall being flexible and arranged to permit contact between at least one of said battery terminals and at least one of said lamp terminals when the illumination device is manually actuated to flex the cavity wall.
Claim 9
Dependent Claim 159 words
In a wristwatch having a case containing a timepiece face portion to be illuminated and a watchband having attachment ends connected at connection means to opposite sides of said case, the improvement comprising a self-contained illumination device including a longitudinal passage adapted to receive one end of the watchband and to slide to a position adjacent to the watchcase, said illumination device having an overhanging portion extending over the watchcase beyond the connection means between the watchband and the watchcase and carrying a lamp arranged to illuminate said face portion, said illumination device defining a cavity containing a battery having a pair of battery terminals, a pair of lamp terminals disposed in the cavity connected to said lamp, a portion of the cavity wall being flexible and arranged to permit contact between at least one of said battery terminals and at least one of said lamp terminals when the illumination device is manually actuated to flex the cavity wall.
