Definitions

  • the invention relates to a flashlight according to the preamble of claim 1.
  • a flashlight is from US 2014/0190802 A1 or the DE 27 46 038 A1 known.
  • Flashlights are an indispensable tool when light is needed in the event of a power outage or as a result of a lack of lighting in nature.
  • the conventional flashlight with a light bulb has been almost completely replaced by flashlights equipped with light-emitting diodes (LEDs).
  • LEDs light-emitting diodes
  • the advantage of an LED is in particular the lower power consumption compared to a light bulb, which means that the maximum lighting time is significantly extended if the battery capacity is available.
  • Light-emitting diodes are also insensitive to impact and shock and have a significantly longer service life of up to several 10,000 operating hours. This is not least because, unlike a light bulb, the majority of the energy supplied is converted directly into light production and not into heat.
  • the on/off switch which can be either a snap-in pressure switch or a button, is located either on the casing or on the front end of the end cap, through which the compartment for the batteries or accumulators is accessible.
  • Conventional flashlights had contact tabs punched out of the casing, which lie in one plane of the casing wall so that they can be viewed from the outside can be grabbed and moved from this level to make contact.
  • Such contact tongues can be connected to a sliding slide.
  • Flashlights with a ring-shaped rotary switch to turn the light on and off are available in the DE 20 2010 010 137 U1 suggested.
  • Such rotary switches can also be used so that, depending on the rotation position, different contact zones are touched to close the current, so that different voltages can be set in the circuit and/or different LEDs can be controlled.
  • Flashlights with a cylindrical housing and a battery cartridge stored therein for removable holder of at least one battery are also known.
  • a slide switch with a slide movably mounted on the housing and a switching arm arranged on the battery cartridge is proposed.
  • Battery cartridges are also proposed which have a pressure switch at the end, which is operatively connected via a push button in the end cap of the flashlight. Between the push button A sealing element is arranged on the pressure switch to create a waterproof yet robust flashlight.
  • the flashlight and a firearm In individual cases, especially in police or military operations, the flashlight and a firearm often have to be used together. In order to ensure sufficient aim, the arms are crossed in the wrist area, with the firearm held in the resting hand and a flashlight in the supporting hand to illuminate the target area. With such a hand position, the operation of a pressure switch arranged on the end cap is just as difficult as the operation of a push or pressure switch arranged on the jacket of the cylindrical housing, which may only have to be located in the dark using keys.
  • the on/off switch consists of an annular body which is arranged to be displaceable in more than one radial direction and by actuation of which a button or pressure switch can be actuated directly or indirectly.
  • the ring body is rigid so that the entire ring can be moved in two, three or four or preferably in any radial direction. In the latter case, the on/off switch can be operated in the hand regardless of the angular position of the lamp because the on/off switch element can be moved radially at any point on the ring body.
  • the radial switching on and off of the type described is also easier to carry out than backward switching, which can only be carried out with the thumb with a flashlight in the closed hand.
  • the term ring body is therefore primarily to be understood functionally and also includes other body shapes that can be moved radially from a position centered on the flashlight to an eccentric position to switch it on and back to the central position to switch it off.
  • the ring body is in contact with at least one body which is spherical, preferably spherical, in the longitudinal axial direction of the cylindrical housing of the flashlight, which is forced by means of a radial displacement from at least one trough of a further body which is elastically mounted in the longitudinal axial direction and thereby triggers a longitudinal axial displacement of this further body , which creates a pressure contact to the button or switch that triggers the switching process.
  • the spherical body part rests in the correspondingly shaped trough, the body of which is under tension so that the mutual position of the parts described is stable.
  • the spherical, preferably spherical body is now displaced in the radial direction by actuating the ring body, this spherical part of the body leaves the trough, so that the further body is displaced longitudinally axially. This longitudinal axial displacement triggers the pressure or push-button contact to the switch.
  • two balls in contact with one another are used in the longitudinal axial direction, each of which rests in a cap-shaped trough until these balls are forced radially out of the trough by a radial displacement of the ring.
  • the balls mentioned are held in a cylindrical tube, the length of which is less than twice the diameter of the two balls of the same size and whose diameter is the same size as the diameter of each ball, apart from a necessary clearance.
  • the balls can thus be moved in a rolling manner in this cylindrical tube, which is associated with correspondingly lower friction.
  • the radial movement also takes place in the form of a rolling movement from the corresponding trough.
  • the further body which is equipped with a trough, is subjected to the pressure of a cap-shaped elastic body on the side facing away from the trough, which has a receiving hole for an arm of the further body.
  • This comprehensive arm is moved longitudinally axially in the direction of the pressure or button switch.
  • the geometry of the balls and the extent of the radial displacement of the ring are preferably chosen so that the ring can be displaced radially to such an extent that the balls roll completely out of the trough, which prevents the balls from "falling back" into the corresponding trough.
  • the ring is pushed back into the centered position, the rolling back being supported by the spring force of the elastic body mentioned as soon as the ball has exceeded the edge of the trough inward.
  • the cylindrical tube mentioned, in which the two balls are mounted, is fastened in a receiving opening of a web or cross profile that is firmly connected to the ring body.
  • the lamp can also have a further pressure switch as an on and off switch on the end face of the end cap, through which a corresponding longitudinal axial displacement of the two balls and thus a pressure switch actuation is brought about.
  • the batteries are preferably arranged in a cartridge which has a pressure switch on one end face, which can be actuated by the described longitudinal axial movement of the switching elements.
  • the structure of a flashlight is basically known according to the prior art, so that only the parts according to the invention will be discussed below.
  • the flashlight has a front light exit opening, a light source which consists of one or more light-emitting diodes and an attachment lens which is preferably longitudinally movable relative to the LED, with which the cone angle of the emitted light can be adjusted from large cone angles up to spot lighting.
  • the power is supplied via batteries 11, which are preferably connected in series in a cartridge (10).
  • the cartridge has a pressure switch 12, the actuation of which closes the circuit in which the LED is contained.
  • Fig. 2 shows the rigid ring body in the starting position in which the ring 13 is approximately flush with the rest of the cylinder body of the flashlight, formed by the cover part 14 and the body 15.
  • Fig. 1 shows the rigid ring body in the starting position in which the ring 13 is approximately flush with the rest of the cylinder body of the flashlight, formed by the cover part 14 and the body 15.
  • the ring 13 is connected via a web 16 to a sleeve 17, which forms a receiving opening 18, into which a cylindrical tube 19 is inserted, which serves as a bearing for two balls 20, 21.
  • the cylinder tube 19 has an inner diameter which is equal to the diameter of each of the same sizes, except for a slight clearance to enable the rotation of the balls 20, 21 Balls 20, 21 is.
  • the tube diameter is slightly tapered at its ends in order to hold the balls 20, 21 captively in the tube 19.
  • the balls 20, 21 rest in troughs 22, 23, the curvature of which corresponds to the radius of the balls 20, 21, whereby the edge regions of the troughs 22, 23 can be rounded.
  • the balls roll out of the troughs 22, 23, with the body 24, which is elastically mounted in the longitudinal direction of the flashlight, experiencing a movement in the direction of the arrow 30 shown.
  • the elasticity is made possible by a curved elastic cap-shaped body 26, which has a central opening for the passage of an arm 27 which is in contact with the switch 28, which is switched by linear movement in the direction of the arrow 25, so that the circuit is closed.
  • the particular advantage of the flashlight according to the invention is that the ring 13 can be moved in any radial displacement to switch on the lamp, so that there is no need to laboriously search for a switch button or button arranged on the casing.
  • the radial displacement of the ring body 13 is possible at least via a path that allows the balls 20, 21 to roll out of the troughs 22, 23, so that the switching on of the flashlight and its switching position caused by the radial displacement are stable and the balls roll back into the troughs only then possible if the ring body 13 is moved radially inwards so far that the balls 20, 21 exceed the edge of the troughs 22, 23 radially inwards.
  • Fig. 7a and Fig. 7b show an alternative embodiment of the invention, in which instead of in Fig. 2 and Fig. 3 used ring body 13, which acts on balls 20, 21, a radially displaceable, essentially cylindrical ring body 31 is used, which has a hemispherical elevation 32 in its center, which is in a trough 22 ( Fig. 7a ) rests or is pushed out of it in the radial direction ( Fig. 7b ), whereby the arm 27 with the anvil part 29 is moved in the direction of the arrow 30.
  • ring body 13 which acts on balls 20, 21
  • a radially displaceable, essentially cylindrical ring body 31 which has a hemispherical elevation 32 in its center, which is in a trough 22 ( Fig. 7a ) rests or is pushed out of it in the radial direction ( Fig. 7b ), whereby the arm 27 with the anvil part 29 is moved in the direction of the arrow 30.
  • the present invention also includes embodiments in which the ring body 13, 31 and its radial displacement path are designed such that the ring body 13 only works as a button, i.e. that the flashlight only remains switched on as long as the ring body is loaded.
  • the end cap of the flashlight can also have a pressure switch known from the prior art, via which the switch 28, 29 can be moved in the direction of arrow 30.
