PREF ,RR .D .MBODIMENT OF THE INVENTION
Referring now to the attached drawings, one embodiment of the present invention will be explained. In this embodiment, the explanation will be given with respect to the situation in which the system is adopted to an automotive lighting system to be attached to the ceiling portion of a trunk room of the vehicle or a compartment thereof.
The numeral 1 denotes a housing having an open bottom side, an open top side and a lateral side formed with a connector receiving portion 11. Said top side of the housing 1 is inserted into a mounting hole & (see a and b- in Fig. 5) formed in the ceiling A of the trunk room - or the vehicle compartment, of the vehicle, said top side of the housing 1 being formed with a flange 12 adapted to close said mounting hole ~. There are further provided a pair of clamp pawls 13 to engage the underside of said ceiling A
such that an incidental separation of said housing 1 from said mounting hole &is prevented. Further, the inside of said housing 1 is formed with a protuberance 14 at a portion corresponding to said connector receiving portion 11 such that a moving contact member 4 which will be explained later is pivoted.
The numeral 2 denotes a first bus bar of electrically conductive material and provided substantially in a channel form as shown in Fig. 6. Said first bus bar 2 is composed of a vertical portion 21 formed with a hole 21& to receive one end of a light source 5 such as a bulb which will be explained later; a horizontal portion 22 perpendicularly bent from said vertical portion 21; a connection piece 23 extending perpendicularly from said horizontal portion 22 to be inserted into said connector receiving portion 11 of said housing 1; and two engagement pieces 22a perpendicularly descending from said horizontal portion 22 to be engaged with the housing 1 when said first bus bar 2 is set in the housing 1.
The numeral 3 denotes a second bus bar provided substantially in the_form of the letter L formed of the same material as said first bus bar 2. Said second bus bar 3 is composed of a horizontal portion 31 having a stationary contact point 31& bent perpendicularly to descend therefrom; a connection piece 32 extending perpendicularly to said horizontal portion 31 to be inserted into the connector receiving portion 11 of said housing 1; and an engagement piece 31b bent perpendicularly from said horizontal portion 31 to descend therefrom to be engaged with the housing 1 when said second bus bar 3 is set in the housing 1.
The numeral 4 denotes a moving contact member made of an elastic electrically conductive metal piece having substantially a hairpin configuration. Said moving contact member 4 has a long leg portion 41 having at a distal end thereof a moving contact point 41a which forms a switch in cooperation with said stationary contact point 31.&. Said long leg portion 41 is formed with a support hole 41b at an intermediate portion thereof in which said protuberance 14 formed in said housing 1 is axially supported. Said moving member 4 also has a short leg portion 41 ' formed with a hole 41c at a position opposite said support hole 41b formed in the long leg portion 41 such that one end of the light sou:rce 5 is inserted into said hole 41c. Further, said moving contact member 4 has an engagement piece 42 extending from a bent portion thereof such that said engagement piece 42 extends to come into engagement with an erected piece 62 of a lens plate 6 which will be explained later.
The numeral 5 denotes a light source such as a bulb or the like having said one Pnd thereof inserted into said hole 41c in the moving contact member 4 and another end thereof inserted into the hole 21a in said vertical portion 21 of the first bus bar 2. The numeral 6 denotes a lens plate having protuberances 61 formed in the lateral side thereof, said protuberances 61 being pivotally supported in holes formed in opposing inner side walls of said housing 1. Said lens plate 6 has longitudinal sides, one of said longitudinal sides is formed with erected piece 62 which engages the engagement piece 42 of the moving contact member 4.
Said housing 1 has another pair of opposing inner side walls which are formed with stops 15 and 16 (see Figs. 3 and 5) adapted to abut against said lens 6 at a bottom face thereof at the time of the swing of said lens plate 6 (to take an open position or a closed position). Further, one of said inner walls is formed with a clicking portion 17 at a position opposite said stationary contact point 31a of the second bus bar 3 such that said clicking portion 17 give a clicking feel at positions where the moving contact point 41a comes into and goes out of contact with said stationary contact point 31a. (See Fig. 5) Next, an explanation will be given as to the method of assembling the lighting system of the invention by use of the parts described in the foregoing. That is, while the first and second bus bars 2 and 3 are being placed at an outer periphery of the floor face side of the housing 1, said engagement pieces 22a and 31b of the respective first and second bus bars 2 and 3 are fixedly inserted into the flanks of the housing 1.
Next, the protuberance 14 is inserted into the hole 41b in the moving contact member 4 by passing the rib (not shown) formed in said protuberance 14 therethrough or by deforming the head of said protuberance 14 through a heating process such that the moving member is swingably supported therein. Thereafter, the light source 5 is fitted in the respective holes 21a and 41c in the first bus bar 2 and the moving contact member 4. Further, the protuberances 61 in the lens plate 6 are pivotally fitted into holes in the housing 1 while the engagement piece 42 of the moving contact member 4 is engaged with the erected piece 62 of the lens plate 6, thus completing the assembly work.
In the thus constructed lighting system of the invention, the connectors of lead wires extending from automotive accessories are connected to the connector receiving portion 11 while the reverse side of the housing 1 is inserted into the mounting hole &formed in the ceiling A
of the trunk room or the compartment of the vehicle, thus locking the pawls 13 for fixation of the housing onto the underside of the ceiling.
Next, the operation of the instant lighting system mounted to the ceiling A of the trunk room or the compartment will be explained.
In a state as shown in Fig. 5a in which the lens plate 6 takes a closed or horizontal position, the engagement piece 42 of the moving contact member 4 is in engagement with the erected piece 62 of the lens plate 6 with said moving contact member having been swung counterclockwise. Therefore, the moving contact point 41a of sai_d moving contact member 4 is brouglit into contact with the stationary contact point 31a of the second bus bar 3; that is, the switch composed of the stationary contact point 31a and the moving contact point 41a is turned on.
Therefore, while the ignition key takes the accessory position, the power is supplied through a closed circuit composed of the second bus bar 3, the stationary contact point 31a, the moving contact point 41a, the moving contact member 4, through the light source 5 to the first bus bar 2 such that the light source 5 is turned on. In this connection, the moving contact point 41a is g:iven a clicking feel by the clicking portion 17 such that said contacting condition is maintained. Further, with the lens plate 6 taking a closed position, the underside of said lens plate 6 abuts against the stop 15 formed in the housing 1 to stop the lens plate from further swinging counterclockwise at this position.
The explanation of the switchover from the on-position to the off-position is given as shown referring to Fig. 5b. That is, the lens plate 6 is swung clockwise until the underside of the lens plate 6 abuts against the stop 16 to press down the engagement piece 42 of the moving contact member 4 in engagement of the erected piece 62 such that the moving contact member 4 per se is swung clockwise, causing the moving contact point 41a to move away from the stationary contact point 31a of the second bus bar 3.
Therefore, the switch composed of the moving contact point 41a and the stationary contact point 31a is brought into an off-position to open said closed circuit such that the power supply to the light source is suspended to turn off the light. Further, upon completion of the clockwise swing of the lens plate, the moving contact point 41a is provided with a clicking feel by the clicking portion 17.
Now, all through during the swing action of the moving contact member 4, the hole 41c into which one end of the light source 5 is engaged is in an opposite positional relationship to the hole 41b such that there is no deflection of the light source 5 during the swing action of the moving contact member 4, thus preventing the light source from dropping off from the first bus bar 2 and the moving contact member 4.
In the aforementioned embodiment, the lighting system of the invention is explained as an automotive lighting system, the invention may be adopted to a general household internal lighting lamp such as a foot lamp, a pillow lamp, a locker lamp, a cloakroom lamp, a lamp for lighting a keyhole of a door or a switching position of the illumination lamp, a preliminary lamp for a stand lamp of a household electrical appliance.
The present invention eliminates the need for a conventionally required independent switch for turning on or off the light source because the bus bars are secured to the housing, a moving contact member is swingably pivoted to the housing, a light source is resiliently held between the housing and the moving contact member, said contact moving member is swung by a lens plate rotatably pivoted to said housing to bring said moving member and said stationary contact point of the second bus bar into or out of contact such that the light source is turned on and off. As a result, the cost is reduced while the structure is simplified.
Further, said moving member is adapted to override a clicking portion at the time of closing and opening the contact points such that the clicking feel is given while the open or closed state may be maintained. As a result, even if the lighting system is adopted to the automobile, a likelihood that vibrations from the vehicle in motion cause the open state to turn into the closed state is prevented.
Further, the lens plate is adapted to abut against the stops formed in the housing at the time of lens swing for turn-on and turn-off operations of the light source such that said light source is prevented from slipping off as a result of lens swing action caused by a strong external force. Further, there is no likelihood of insufficient contact due to the moving contact point passing the stationary contact point. There is a further effect that the connection work to the external power source is easily done by use of connectors since bus bars are provided as stationary conduction members extending to the connector receiving sections of the housing.

The numeral 3 denotes a second bus bar provided substantially in the_form of the letter L formed of the same material as said first bus bar 2. Said second bus bar 3 is composed of a horizontal portion 31 having a stationary contact point 31& bent perpendicularly to descend therefrom; a connection piece 32 extending perpendicularly to said horizontal portion 31 to be inserted into the connector receiving portion 11 of said housing 1; and an engagement piece 31b bent perpendicularly from said horizontal portion 31 to descend therefrom to be engaged with the housing 1 when said second bus bar 3 is set in the housing 1.
The numeral 4 denotes a moving contact member made of an elastic electrically conductive metal piece having substantially a hairpin configuration. Said moving contact member 4 has a long leg portion 41 having at a distal end thereof a moving contact point 41a which forms a switch in cooperation with said stationary contact point 31.&. Said long leg portion 41 is formed with a support hole 41b at an intermediate portion thereof in which said protuberance 14 formed in said housing 1 is axially supported. Said moving member 4 also has a short leg portion 41 ' formed with a hole 41c at a position opposite said support hole 41b formed in the long leg portion 41 such that one end of the light sou:rce 5 is inserted into said hole 41c. Further, said moving contact member 4 has an engagement piece 42 extending from a bent portion thereof such that said engagement piece 42 extends to come into engagement with an erected piece 62 of a lens plate 6 which will be explained later.
The numeral 5 denotes a light source such as a bulb or the like having said one Pnd thereof inserted into said hole 41c in the moving contact member 4 and another end thereof inserted into the hole 21a in said vertical portion 21 of the first bus bar 2. The numeral 6 denotes a lens plate having protuberances 61 formed in the lateral side thereof, said protuberances 61 being pivotally supported in holes formed in opposing inner side walls of said housing 1. Said lens plate 6 has longitudinal sides, one of said longitudinal sides is formed with erected piece 62 which engages the engagement piece 42 of the moving contact member 4.
Said housing 1 has another pair of opposing inner side walls which are formed with stops 15 and 16 (see Figs. 3 and 5) adapted to abut against said lens 6 at a bottom face thereof at the time of the swing of said lens plate 6 (to take an open position or a closed position). Further, one of said inner walls is formed with a clicking portion 17 at a position opposite said stationary contact point 31a of the second bus bar 3 such that said clicking portion 17 give a clicking feel at positions where the moving contact point 41a comes into and goes out of contact with said stationary contact point 31a. (See Fig. 5) Next, an explanation will be given as to the method of assembling the lighting system of the invention by use of the parts described in the foregoing. That is, while the first and second bus bars 2 and 3 are being placed at an outer periphery of the floor face side of the housing 1, said engagement pieces 22a and 31b of the respective first and second bus bars 2 and 3 are fixedly inserted into the flanks of the housing 1.
Next, the protuberance 14 is inserted into the hole 41b in the moving contact member 4 by passing the rib (not shown) formed in said protuberance 14 therethrough or by deforming the head of said protuberance 14 through a heating process such that the moving member is swingably supported therein. Thereafter, the light source 5 is fitted in the respective holes 21a and 41c in the first bus bar 2 and the moving contact member 4. Further, the protuberances 61 in the lens plate 6 are pivotally fitted into holes in the housing 1 while the engagement piece 42 of the moving contact member 4 is engaged with the erected piece 62 of the lens plate 6, thus completing the assembly work.
In the thus constructed lighting system of the invention, the connectors of lead wires extending from automotive accessories are connected to the connector receiving portion 11 while the reverse side of the housing 1 is inserted into the mounting hole &formed in the ceiling A
of the trunk room or the compartment of the vehicle, thus locking the pawls 13 for fixation of the housing onto the underside of the ceiling.
Next, the operation of the instant lighting system mounted to the ceiling A of the trunk room or the compartment will be explained.
In a state as shown in Fig. 5a in which the lens plate 6 takes a closed or horizontal position, the engagement piece 42 of the moving contact member 4 is in engagement with the erected piece 62 of the lens plate 6 with said moving contact member having been swung counterclockwise. Therefore, the moving contact point 41a of sai_d moving contact member 4 is brouglit into contact with the stationary contact point 31a of the second bus bar 3; that is, the switch composed of the stationary contact point 31a and the moving contact point 41a is turned on.
Therefore, while the ignition key takes the accessory position, the power is supplied through a closed circuit composed of the second bus bar 3, the stationary contact point 31a, the moving contact point 41a, the moving contact member 4, through the light source 5 to the first bus bar 2 such that the light source 5 is turned on. In this connection, the moving contact point 41a is g:iven a clicking feel by the clicking portion 17 such that said contacting condition is maintained. Further, with the lens plate 6 taking a closed position, the underside of said lens plate 6 abuts against the stop 15 formed in the housing 1 to stop the lens plate from further swinging counterclockwise at this position.
The explanation of the switchover from the on-position to the off-position is given as shown referring to Fig. 5b. That is, the lens plate 6 is swung clockwise until the underside of the lens plate 6 abuts against the stop 16 to press down the engagement piece 42 of the moving contact member 4 in engagement of the erected piece 62 such that the moving contact member 4 per se is swung clockwise, causing the moving contact point 41a to move away from the stationary contact point 31a of the second bus bar 3.
Therefore, the switch composed of the moving contact point 41a and the stationary contact point 31a is brought into an off-position to open said closed circuit such that the power supply to the light source is suspended to turn off the light. Further, upon completion of the clockwise swing of the lens plate, the moving contact point 41a is provided with a clicking feel by the clicking portion 17.
Now, all through during the swing action of the moving contact member 4, the hole 41c into which one end of the light source 5 is engaged is in an opposite positional relationship to the hole 41b such that there is no deflection of the light source 5 during the swing action of the moving contact member 4, thus preventing the light source from dropping off from the first bus bar 2 and the moving contact member 4.
