Description

a lock are locked in place, which in a of an .lehrzahl of at the same distance on the gears Attacks attached pins. To ignite a lamp, the interlock is briefly released by one to enable rotating progression of the gears, whereupon one of the Eampen triggers a hammer. In Another embodiment is a lamped one spring-loaded sliding slider linearly incremented in a corresponding manner ·.

Background of the invention

The invention relates to flash assemblies for a. Variety of flash lamps and in particular an arrangement of flash lamps which can be ignited by impact and which have their own energy provided device ^ for selectively controlling the ignition of the same.

For flash units, the trend is towards the use of sub-miniature flash lamps (with a piston volume of less as 1 cnr) in compact, single-use clock lamp units, to give camera users the advantages of greater convenience, compactness and portability allow. A currently popular flashlight facility this species is commonly known in the band as a lightning cube, a particular embodiment of which is described, for example, in U.S. Patent 3,327,105. This unit has a set of four flashlights, each with its own yeast deflector, mounted on a base plate attached and enclosed in a transparent cover. Each lamp-reflector arrangement points into a corresponding one seal the four side walls of the cube. One of the focal points the bit cube base plate made of downwardly protruding pegs is used to hold the unit in a kouipleiuentäreu. Jack on a camera. During operation, the flash

dice rotated a quarter turn at a time, usually depending on each actuation de.r film transport device of the camera, one after the other unused lamps in one opposite the photographed object Bring the ignition position. Each flashlight consists of a hermetically sealed, translucent glass bulb, which is a thread-like combustible material, such as machined zirconium foil, and a gas that promotes combustion, such as oxygen, contains. In the case of the "use of lightning cubes with electrically ignited lamps, there are two power supply wires Introduced into the lamp vessel in order to create a thread in connection with beads of Zündiiiasse inside it to wear. When the flash cube is in the ignition position, there are sections located outside the lamp envelope the electricity supply wires in permanent connection with electrical contacts in the camera mount, which in turn are connected to the A cheese-based power source, usually a pair of dry cell batteries, When a photographer uses the shutter release device operated to "snap" a picture, the same action closes the electrical one Circuit from the batteries to the ignition system in the lamp, thereby causing the flash lamp to flash. The ignition timing of the combustible material in the lamp is with the exposure of the film by pressing the shutter release synchronized, so that an effective use of the light from the flash lamp is achieved.

It is not a rare problem that the average person faces However, the amateur photographer when using a battery-powered flash system is faced with that .Lamp ignition failure due to weak batteries and / or dirt or corrosion on one or more of the

409827 / 062.8

electrical contacts in the system. To fix this problems and to improve flash lamp reliability Flash lamps that can be ignited by blows have been developed which can be ignited mechanically without the need for batteries. From U.S. Patent 3,535,063 is For example, it is known that such flash lamps are fused into one end of the lamp instead of power supply wires have mechanical detonators. This igniter can be a metal tube protruding from the lamp bulb and a Charge of ignition material on one in the flask, aged Have wire. The ignition of those ignitable by impact The flashlamp is introduced into the tube by a switch, in order to deflagrate the ignition material upwards through the To cause the pipe through to ignite the fuel arranged in the lamp bulb »the ignitable by impact Lamps are also manufactured in sub-miniature bulb sizes and in flash cube units that can be ignited by impact used, which preloaded correspondingly assigned to each lamp As in U.S. Patent 3,597 $ 04 described. The lightning cube, which can be ignited by blow, is in in the same way as the electric lightning cube in the ignition ^ position advanced; ax to use the flash lamp However, due to the action of one of the camera shutters ^ direction assigned part-ignited, which is through the Lightning cube base plate moved upwards through it to trigger the corresponding preloaded hammer spring, see above that this hits strongly against the ignition tube of the lamp.

Another "development" in the art of cattle lamp flash assemblies for added convenience and versatility is to provide a linear or planar array of flash lamps. In such an arrangement a plurality of lamps is in the direction of the photographed object, ^{so: that:} it is possible to quickly from

409827/0828

one lamp to another or more than one Flashing the lamp at the same time when additional light is required. Examples of already described Flash lamp fields are known from the following US patents: 3,267,272, 3,430-545, 3,430,315, 3 454 756, 3 458 270, '3 473 880, 3 500 732, 3 544 251, 3 545 904, 3 443 075, 3 552 896, 3 562 508, 3 598 984, 3 596 985, 3 608 451 and 3 614 412.

In all of these patents electrically excited flash systems are described in which the lamp flash sequence is controlled by various electrical switching devices, which include: manually operated spring sliding contacts; a rotary switch; thermally or chemically reacting switches, which are arranged in the thermal vicinity of the flash lamps are; a switch within each lamp bulb, which closes when it is ignited, to the next lamp prepare in the i? oige; a voltage surge across the lamps only causes the lamp to ignite which has the has the lowest ignition or breakdown voltage; Bimetal switch; a fusible link within each lamp envelope and finally plague body circuits. Although they have a number of advantages, the electrical arrangements, still have the reliability problems associated with an electrical lightning system, viz Ignition failure due to weak batteries and / or dirty or corroded electrical contacts.

Another disadvantage of electrical assemblies is that it is relatively difficult to find the correct one Follow the lamp ignition sequence when the arrangement of a Camera is removed and then put back on. To overcome this problem are in the known arrangements, as described above, special flash lamps or

In the particular embodiment shown in FIGS. 1-3, the ^N flash lamp arrangement has a group of eight axially arranged flash lamps 10 and associated coaxial reflectors 12 ″, which are arranged in a compact flat field which contains two rows of four lamps arranged one above the other The lamp field is accommodated in a box-like housing 14: "which has an essentially flat lower part 16, an essentially flat holding part 13," which is attached to the lower part 16 and is generally arranged at right angles to it, two side walls. 20 and 22 and a top wall 24. The parts 16-24 can form a one-piece arrangement of molded material or the holding part 18 can be fastened separately. " The envelope is completed by a thin plate 26 made of a transparent plastic, which is attached to the housing 24 as a front wall and above the light-emitting. Side of the field is arranged.

According to the illustration in FIGS. 2 and 3, the flash lamps are 10 on one side ^ des. Keep files 18 with ai this . Vertical longitudinal axes, mounted «In addition, there are 18'3 eight pre-tensioned impact springs 28 mounted, which -during this, are arranged in such a way that they-each have a corresponding Lamp effectively assigned are. As explained in detail below, the hammer springs are each can be triggered individually, 'around the correspondingly assigned lamp to ignite.

According to FIG. 2 , the selective actuation device according to the invention has a coplanar gear train of two intermeshing gear rings 30 and 32, each of which has a number. carried by circumferentially spaced and protruding ramps 34. The gears are rotatably mounted on two shafts 36 and 38, each of which is rigidly fastened at one end to the holding part 18. The shafts are preferably formed by ropes of the holding part 10, which have been produced as a common part thereof. The free end of each ί / elle has an im. essentially flat surface parallel to the plane of the gear wheel mounted thereon and the gear train is arranged parallel to the holding part 18. In order to enable the desired interaction between the gear device and the lamp ignition springs, a "bundle of four lamps 10 and four supplementary springs 28" is arranged symmetrically on the end face of each gearwheel shaft, so that a lamp field with a total of eight lamps is formed, which consists of two parallel lamps Rows of four equidistant lamps,

1 and 3, each concave reflector 12 is coaxial about its associated cylindrical lamp 10 arranged around, with all reflectors aligned so that they are in a Point away from the lamp holding surface. Any reflector

409827/0828

is essentially parabolic, but modified by the provision of four surfaces 59 along its sides. Collide with neighboring flat surfaces from neighboring reflectors together to form a compact flat array of reflectors. According to Figures 2 and 5, the hairpin-shaped torsion parts the group of four springs 28 on each shaft, bundled in the central space, which is behind each quadrangle group is formed by four reflectors. . . .

The array of eight reflectors 12 can be a single preformed one forming a thin sheet 40 of plastic bearing a light reflective coating; for example can the inwardly curved reflector surfaces 12 by vacuum molding A coaxial opening 41 of suitable shape is formed towards the apex of each reflector, which fits around the cylindrical flash lamp 10. If the emission from a flashed lamp turns out to be a problem by using a coupled ignition of a not selected lamp can cause the parabolic reflector edge 12 be extended so far back that the entire Lamp bulb is essentially covered, instead of leaving a free part as shown in FIG. 5. The overall arrangement of a package of a similar lamp refconductor arrangement is the subject of a on June 6, 1972 • filed and assigned to the applicant of the present application assigned US application pending under serial number 260 271.

As particularly shown in FIG. 4, each lamp 10 has an airtight, translucent, cylindrical .derformigen one Piston 42 with a detonator protruding from it. A filling made of flammable foil. 43, such as Zircon and a gas that promotes combustion, such as oxygen, are located within the

4 09827/08 2 8

Piston. The igniter consists of a metal tube 44, which projects coaxially from the piston and within which a Wire anvil and a charge of ignition material are arranged. Each lamp is on the holding part i8 '- by means of a corresponding one Bore 46, into which the ignition tube 44 is inserted, supported in such a way that it protrudes from this at right angles and is thus axially parallel to the lower part 16. This means that four bores 46 are formed in each shaft end face, such as shown in Figure 2. Each pretensioned striker spring has a bent torsion part - which typically from a 0.53 mm (0.021 inch) wire side with a Length of about 63.5 mm (2.5 inches). The wire is bent so that it has a hairpin-shaped torsion part with sections 47 and 48 which are connected to one another by a loop 50. The end part of section 47 is shaped so that it forms a fixed support foot 52, the tip of which is shaped into a stop 54.Teile des Fuß 52 and the stop 54 are not visible in FIG. The end part of the section 40 is shaped into a hammer 56, which, when the spring has stored energy or is tensioned, crosses the retaining foot 52 and through the stop is recorded as shown. The fixed retaining foot sits in one in the circular end face of the gear shaft elongated slot formed on or near a diagonal of the same, which is only so deep is that the stop 54 projects beyond the end face of the shaft.

Initially, the hammer $ 6 may be formed at an angle of approximately 90 ° to the fixed support foot 52, although the angle through which the hammer is rotated to position it behind the stop 54, as shown, can have any value does not cause excessive strain on the wire.

.Each gear shaft forms a suitable bearing surface for the rear end of the additive during tensioning and carries in addition to this, -a accidental displacement of the spring 28, which some for freeing the slugger from the stop Sufficient time after tensioning and before the intended ignition. ■

A selective displacement of each tensioned hammer 56 to move it from the stop 54 · to. free and thereby allow him to strike the corresponding igniter tube 54 · and to ignite the associated lamp 10, is effected by turning the gear train. In particular, the ignition springs 28 are arranged as shown in Figure 2 on each Ir / Elle so that the aggregates 56 form a symmetrical radial pattern., And protrude beyond the circumference of the circular face that they are part of the gear mounted on the shaft in question The free ends of the aggregates 56 are arranged, in particular, in such a way that they lie in the path of movement of the ramps 34- which protrude from each gear wheel. As the gear train continues to rotate, the aggregate adjacent to one of the incoming ramp 34-, as shown in FIG. printed by the ramp up a distance which is sufficient to bring it over the top of the stop 54-. The hammer then swivels clockwise, as indicated by the arrow, and hits the impact-sensitive igniter tube 4A and 4A at a high speed notches this in order to cause a deflagration of the ignition material located in this and thereby ignite the flammable foil 4-3.

The rotating progression is initiated by external gowns, but the need for external energy is according to the invention reduced to a minimum by an actuating device which has its own energy and actuates the photoflash arrangement, what happens in the following way. As can be seen from FIGS. 5 and 6, there is a flat spiral spring 60 mounted on shaft 36 (and / or 38) oad with the gear 30 (or 32) connected to this shaft for a sufficient

409827 / Ό828

To create spring loading, the gear seeks to rotate around its shaft. The indexing of the gears is controlled by engaging and releasing the indexing stops, which consist of a plurality of on the circumference of each of the gears Ix. There are spaced apart pins. Going into more detail, as can be seen from FIG. 2, eight pins 61-68 are arranged along the circumference of gear 30 and eight pins 71-78 are evenly spaced from one another along the circumference of gear 32 in order to shift the gear train in eight equal steps The pins each protrude perpendicularly from the plane of the gearwheel, as shown in FIG.

To lock the position of the spring-loaded gears, a releasable locking device engages in one of these indexing pins. As shown in Figure 2, the locking device can have a lever arm 80, which can be given by a centrally arranged pivot bearing such as a pin 82 _; is carried by the holding part 18. The lever arm 80 is provided at each of its ends with projections 84 and 86 for alternating engagement with the indexing pins on the two adjacent gears and is spring-loaded by means of a spring 88 fastened on the lower part 16 in order to usually assume a substantially horizontal position, as in FIG 2 shown. In this normal or locked position, the projection 86 of the lever arm engages in one of the indexing pins of the gear wheel 32.

In the embodiment of Figure 2, the spring load applied to the lever arm below the projection 86 and the lever arm below the projection 84 remains free for access by an external actuating device which can act through an opening 90 in the lower part 16.

409827/0828

For example, the gear wheel can be switched by a suitable Actuator 92 happen, which by the öff tion 90 moves up to on the lever arm below des'Vorsprungs 84- to attack this and press against it. The upward movement of the actuator 92 is conditional an upward movement of the left side of the lever arm and the downward movement of its right side, whereby the Projection 86 out of engagement with your stop pin f / 1 des Gear 32 comes and the spring-loaded gear train can turn, in this case the gear 32 rotates clockwise and the gear .30 counterclockwise. The gear wheel rotation represents a short-term advance movement, because the. Wave! Shift will end as soon as the raised;! projection. 84 of the lever arm on pin 61 of the Gear 3G engages. If the actuator 92 daaaeh withdrawn again, the spring-loaded lever arm "returns to its horizontal position, whereby the projection downwards out of engagement with the pin 61 of the gear 3ü oewegt and the projection 86 upwards in snapping Engaging with the indexing pin 72 of the gear wheel 32 moves and locked the position of the Häderwerk again. Which angular displacement resulting from the above operating sequence is determined by the uniform distance between the shift pins on a gear and .in the present Embodiment effective with regard to the ignition of a lamp. In a typical application, the actuator 92! Be part of a camera mechanism that enables the The aim is to enable the photographer to use a lamp synchronously with the release of the camera shutter to take a picture flash.

In the 'present flash lamp arrangement there are eight lamps' are available to start sequentially, depending on the successive switching of the sowing unit through the

Part 92 getting flashed. Therefore, for example, eight rapid flash exposures can be made with one camera without it being necessary to move the lamps or to rotate the unit by their location on the perimeter on each. Gear programmed. That is, the ramps 54- are arranged in such a way that, for a selected step χ of the rotary adjustment, the gear movement causes a first ramp in the gear train to trigger a hammer and that a second ramp in the gear train moves into a position next to a further prestressed hammer 56 is moved as shown in FIG. This overturning ramp positioning then continues for all of the following χ turning steps until all springs have been triggered. Typically, each indexing cycle produces a step χ of gear rotation to cause a single lamp to ignite. The new position of the gear train is locked after each indexing cycle by means of the spring-loaded lever arm, which moves the projection to engage the next pin of the Gear 52 returns. Due to the mechanical ignition system, the ramp programming and the control by the spring-loaded lever arm, a memory function is built into the present photo flash arrangement, through which the next unused lamp in the flash sequence will always be ready for immediate triggering, although the unit has been removed from a camera and can then have been put back on. This is a significant advantage compared to. the electrical arrangements.

In a typical embodiment of the invention, as in Figure 2, two sprockets 50 and 52, which 32 teeth each and a diameter of 25.4 mm (1 inch) have, each mounted on a holding part 10, which is about Measures 1.5 inches by 2.55 inches (58.7 mm by 64.3 mm). On every

On the other hand, the slide 168 can be retained in the channel by lugs 178,. which protrude at right angles from the underside of the slide and engage in a groove 180 (FIG. 10) along the lower part of the side wall of the channel 176.

The preloaded supplementary springs 135-138, which zu.den Lamps 125-128 are supported in a direction opposite to the sighting of springs 131-134, as in FIG Figure 8 shown. The lower part 112 therefore forms a further longitudinal channel 182 in the vicinity of the hammer Springs 135-138; it has a periphery over which the tensioned slides of the springs protrude. The channel 182 runs parallel to channel 176 and the two strings of flashlights | are parallel to these channels between the same arranged. Another slide 184, which has four linearly spaced ridges 191-194 at, is in the channel 182 held below the neighboring hammer. The slide 184 can move in one direction to the advancing direction Slide 168 can be indexed in the opposite direction to selectively operate springs 135-138 in the same manner to be triggered as described above for the triggering of the springs 131-134 by the slide 168. That means if that The lower part 112 is rotated by 180 °, the slide 184 also moves from left to right.

The reflector fields 140 and 142 are essentially identical

table.; each comprises a strip of preformed thin Plate material, which has a light reflective coating and forms a set of four inwardly curved, individual right reflector surfaces 186, the shape of which is chosen as follows: is that they fit around appropriate flash bulbs. As shown in Figure 7 "U-Hd. 8, each reflector of both 140 behind a corresponding flash lamp of the row of lamps 121-124. When one of the Flash lamps 121-124 therefore reflect the surface 186 behind the lamp in question light into that sighting into which the lamp-reflector unit points.

The four reflectors of the panel or array 14-2 are on the other hand arranged accordingly behind the four flash lamps of the row 125-123, so that they are in the sighting of the reflectors of the field 140 opposite direction point. According to Figure 7 and S, therefore, includes the flash assembly 110 a symmetrical arrangement of reflectors, lamps, Springs and switchable operating slides, which form two operational flash lamp fields that are in opposite directions Directions. The hairpin-shaped Torsion sections of the springs are housed behind the reflectors (Figure S), with a margin along the The lower edges of the reflectors are provided so that the hammer is not obstructed.

According to the invention, the progressive advancement of each displaceable slide caused by its own energy is achieved in the following manner, as can be seen from FIGS connected to the right end of the channel 176 in order for a sufficient spring loading ^to: ensure that the slider 168 along the channel 176 of

to move left to right seeks. In Figure 9, a portion of the slide 168 has been broken away to reveal the internal connection between the spring 196 and the slide. The progressive movement of the slidable spool is controlled to each other by engagement and triggering a Liehrzahl linearly spaced indexing pins on the ■ side of the slider, xviehr going to the individual are to stepping of the displaceable slider 166 in four equal increments'] to each other in the same spaced pins 201 to 207 provided along the top of the slide, as shown in FIGS. 9 and 11. Each of the pins extends parallel to the plane of the holding part »

In order to lock the position of the spring-loaded slide, a releasable locking device slides on one of these Pins in a similar way to how it was described above in the reference on the gear train was depicted. As from the figures 9 and 12 can be seen, the locking device a ^ s_ a .Lever arm 210 exist, the .by means of a centrally arranged For example, a pivot point configured as a pin 212 is attached to the lialteteil- 112. The lever arm 210 has projections 214- and 21-6 at each of its two ends that serve to alternately engage the first and last of a linear set of four pins. The lever arm 210 is loaded by a spring 218 attached to the holding part 112 is attached to the lever arm in a substantially horizontal position To hold position, as shown in Figures 9 "^ and 12 is. In this normal or locked position, the projection 216 engages in one of the indexing pins of the Slide 168 a. An elongated recess 220 in the holding part 112 creates space for the pins 201-20? and the spring-loaded lever arm 210, which is attached to one side of the recess, while the spring 216 is at the bottom of the Recess is attached.

In the illustrated embodiment, the spring load acts on the lever arm under the projection 216 and the lever arm under the projection 214 is exposed to an actuating device reaching through an opening 222 in the holding part 112. For example, the jamming of the slide can be effected by a suitable actuating member 224, which moves up through the opening 222 in order to engage and press against the lever arm under the projection 214. The upward movement of the actuating member 224 lifts the left side of the lever arm 210 and lowers its right side, whereby the projection 216 koißjit out of engagement with the pin 201 and allows a movement of the spring-loaded slide from left to right along the channel 176. The slide movement means a short-term advance, since the linear displacement is ended when the raised projection 214 of the lever arm engages the pin 204 of the moving slide. Thereafter, when the actuator 224 is withdrawn, the spring-loaded lever arm returns to its horizontal position with the protrusion moving downward and disengaging from the pin and the protrusion 216 moving upward and into snapping engagement with the indexing pin 202 comes, so that now the "position of the slide is locked again. The angular displacement in consequence of the aforementioned operating sequence is determined by the linear distance between the indexing pins on the slide and causes a lamp to ignite in the embodiment shown here.

In a typical application, the actuator 224 may be part of a camera mechanism that controls the The aim is to enable the photographer to take a picture in sync with the release of the canopy closure

mera be modified, un. the sensor for the operation remove or the Jeder 218 would suffice to release the lever arm 210 from the triggering of the gears Vv-uring the scanning movement to protect the actuator.

In the lamp arrangement 110 shown, there are eight lamps available to sequentially in abaängiglceit- from the continuous Further switching of the handler by the actuating element 224 to be ignited. In particular, with " Retaining pin 226 pushed into the above-mentioned camera four rapid flash exposures are made with one camera, by consuming lamps 121-124 one after the other. The arrangement is then removed from the camera and turned around and put back on to the unused lamps 125-128 and pre-tensioned slugs 135-135 in the factory exhibition In this case, the retaining pin 227 is pushed into the camera base, while the retaining pin

identical to slide 168 (with own energy Incremental means) and the channel 182 contains a üffnaxv ;, which is equal to the opening 222, through which the slide 184 rotated by the part 224- in the latter. If the arrangement can be switched further. The Larüpen 125 to 128 can then be ignited sequentially in the same way as lamps 121-124.

The triggering sequence of the hammer depending on the continuous advancement is determined by the number and the appropriate place of attachment of the lamps along each slide programmed. In the present case, four ramps are arranged on each slide, so that a selected one Shifting step χ along the corresponding channel causes the slide movement to have a first ramp triggers a hammer on the slide in question and that a second ramp on this slide in a position in the vicinity of another prestressed hammer This ramp positioning pattern applies to all successive steps χ of the shift continue until all four springs have been released.

For example ^ according to Figures 9 to 11, are in a Embodiment the springs 151-154- at regular intervals from each other with a common distance D between the beaters (Figure 8). Each of the caterpillars 171 t174 is for triggering a corresponding hammer spring of springs 151-154 and each subsequent lia ^ pe after the first ramp (ramp 171) is from its previous one.

Thus, according to FIG. 11, ramp 171 is arranged in the vicinity of the hammer spring 151, which ■ is the first spring to be triggered in the firing order. Hamp172 is away from ramp 171 by D + (2-i) x = D + χ 173 is D + 2x away from ramp 172, and Ramp 174 is ^ by D + 3x away from ramp 173 as a spring release sequence: (1) spring 131 by ramp 171; (2) spring 132 through ramp 172; (3) spring 133 through ramp 173; and (4) spring 134 through ramp 174. The new position of the gear train is activated after each switching cycle by means of the spring-loaded Locked lever arm 210, which returns the protrusion to the next pin on the slider to attack. Thus, due to the mechanical ignition system, the ramp programming and the .Peder lever control the present Photo flash arrangement has a built-in storage function with the next unused lamp in the flash sequence is ready for instant triggering, even when the unit is removed from the camera and put back on should have been.
