The subject inventions relate to flashlights and other battery-powered apparatus for holding and energizing electric transducers.
Battery-Powered apparatus for holding and energizing one or more electric transducers are well known and include flashlights, laser pointers, and electrically powered tools, to name a few examples.
There also is a need for improved transducer mounts or housing in battery-powered apparatus.
It is an object of one of the inventions herein disclosed and claimed to provide improved rechargeable battery-powered apparatus for holding and energizing at least one electric transducer, wherein any transducer is isolated from battery chargers and charging currents, whereby transducers are protected and charging current limitations imposed by transducers are avoided, and wherein battery charging currents are led through parts of the apparatus without the need of any electrodes, wires and the like that would have to be electrically insulated from the apparatus part through which the particular electrode or wire proceeds.
That invention resides, in combination, in a light source having a base, a light source energizing circuit having an electric switch for a light source in that energizing circuit, a part of that switch releasably fastened outside of said base to a support for that part of the switch, and the light source mounted on that part, whereby the light source is disposable with that part of the switch on which it is mounted. The invention may extend to a replacement for that part of the switch, and a replacement light source mounted on the replacement for that part of the switch.
The subject inventions and their various aspects and objects will become more readily apparent from the following detailed description of preferred embodiments thereof, illustrated by way of example in the accompanying drawings, in which like reference numerals designate like or equivalent parts, and in which:
The drawings show battery-powered apparatus 10 for holding and energizing an electric transducer producing an output from a battery current. One or more batteries 11 may be held in the battery housing. Apparatus within the scope of the invention include flashlights, laser pointers, electrically powered tools, and other devices. Accordingly, the transducer may include one or more light bulbs 12 and/or 13, laser diodes or other battery energized light sources, electric screw drivers or other torque converters, or other electric actuated tools or devices. The output correspondingly may be a high or low beam or other light output 14 and/or 15, or a torque or other physical quantity, but no limitation in this respect is intended hereby.
The switch actuator 17 or 32 is threaded to the battery housing 16 or barrel 31 for rotary and axial movement relative to that battery housing or barrel. The expression “threaded to” in this respect is intended to be broad enough to cover “threaded in” as in the case of the transducer mount 17, “threaded on” as in the case of the end cap 32, to name two examples.
A push-button on/off actuator 127 may be coupled to or integral with the common switch element 27 in circumvention of the threaded switch actuator or end cap 32. According to FIG. 1, the common switch element 27 has a manually engageable portion 127 extending through an aperture in the end cap or its annulus 132. The expression “manually engageable” is intended to be broad enough to cover engagement through a sealing diaphragm 327 or similar device that may be part of the resulting on/off push-button shown in FIG. 1 and schematically in FIGS. 3 and 4 at 127.
b. keeping any second transducer energizing switch (e.g. 30) out of the battery charging circuit (e.g. 21 and 22), thereby avoiding the need of users having to set two switches in series before charging can take place and thereby avoiding the charging current limitations imposed by prior-art systems which charge through a flashlight filament.
By way of example, the switch 26 may be a single-pole double-throw switch, with or without an open third position for deenergization of the transducer or of the battery charging circuit in alternate switch positions 41 and 42. In this respect, the expression “double throw” is intended to be broad enough to cover “triple-throw” or “multithrow.”
Conversely, the rotary switch actuator 32 releases the third switch contact part 27 into electrical connection with the conducting resilient portion 29 in circumvention of the insulating spacer 37 upon actuation to the second angular and axial position 42. In that case, the end cap or actuator 32 and its electrode 24 are connected to the battery terminal 19 for a charging of the battery via electrode or terminal 24, end cap or actuator 32, resilient second switch, contact part 129-29, third switch contact part 27 at lugs 227, and battery terminal 19.
If different light outputs 14 and 15 are desired, a light bulb with high-beam and low-beam filaments could be used. However, according to the preferred embodiment shown in FIGS. 1, 2, 4 and 5, the flashlight has two separate lamps 12 and 13, one high power, the other low power, and both lamps are mounted in a single reflector 36, with the higher power lamp 12 mounted in a central opening in the reflector and having its filament 112 located at the focus of the reflector, and thus having its beam 14 focused by that reflector, and the lower power lamp 13 being mounted off to the side of the high power lamp 12 in a second opening in the reflector and thus out of focus in the reflector 36. In consequence, the low power lamp 13 does not use the reflector to focus its beam 15, but instead may use a lens 117 on the front of the transducer mount 17. According to a preferred embodiment of this aspect of the invention, there is a refractive lens 213 for the second or low power lamp 13, which may be directly on that lamp for focusing its beam. As shown in FIGS. 1 and 2, the lower power lamp 13 is oriented for generating its light beam 15 along a generally similar direction as the light beam 14 of the higher power lamp 12. For example, as shown in FIGS. 1 and 2, the higher and lower power lamps 12 and 13 may be oriented substantially parallel to one another, pointing in substantially the same direction. As further shown in FIGS. 1 and 2, the lower power lamp 13 is recessed in its reflector opening with its refractive lens 213 exposed in the reflector 36, preferably with its refractive lens 213 adjacent to the reflector 36 at the reflector opening in which the lower power lamp 13 is recessed.
Both lamps 12 and 13 thus would be deenergized at that point. In practice, this may not be desirable, since it could confuse the user or provide an opportunity for a supposedly switched-off flashlight to switch itself “on” through a relatively slight accidental motion between its transducer mount 17 and barrel 31, thereby unnecessarily draining the battery.
That tang or projection is shown as an arc 153 in FIG. 4, since it maintains both contact parts 53 and 57 in contact with the first contact part and thereby lamps 12 and 13 energized, while the switch 30 switches the flashlight 10 from one lamp 12 to the other lamp 13; that is, while the switch actuator or lamp mount 17 goes through its rotational and axial position 147.
The flashlight may have a reflector module, such as shown at 17 and the part 54 of the switch including the first and second portion 53 and 75 may be mounted on that reflector module as a support of that part 54. The first and second lamps 12 and 13 extend into that reflector module 17, as seen in FIGS. 1 and 2.
The above mentioned part 54 of the switch may have a fourth contact 18 in the light source energizing circuit 20, and the first lamp 12 is then connected between the second and fourth contacts 53 and 18, such as by wires 58 and 59, whist the second lamp 13 is connected between the third and fourth contacts 75 and 18, such as by wires 72 and 73.
Where the reflector module 17 is threaded to the module support 31 for rotational and axial movement relative to that module support, the first position is a first rotational and axial position 45 of the reflector module 17 relative to its module support 31, the second position may be a second rotational and axial position 46 or 47 of that reflector module relative to its module support and the third position may be a third rotational and axial position of the reflector module relative to this module support.
