Definitions

  • the present invention relates to portable lights more particularly those lights which are convertible between a flash light mode and lantern mode. More particularly the invention relates to handle assemblies for such flash lights.
  • Prior art portable lights are generally either lanterns or flash lights.
  • flash lights which are convertible between lantern mode and flash light mode has led to particular difficulties relating to the ability to grip and properly utilise the portable light particularly when large battery or storage cells are used.
  • the object of the present invention is to substantially overcome at least one of the disadvantages of the prior art by providing a single handle assembly which can serve as a handle in either mode of use i.e. either as a flash light or as a lantern.
  • a handle assembly for a portable light said portable light being convertible between a flash light and a lantern
  • said handle assembly including a handle means whose ends engage the body of the light characterised such that a part or all of said handle means can be moved from a first arrangement in which said handle allows the light to be gripped as a flashlight to a second arrangement wherein said light can be gripped as a lantern.
  • said flash light is convertible into lantern mode.
  • both ends are movable or are either detachable and replaceable or are slidable from their respective securing locations.
  • the hand gripped portion of said handle means is symmetrical so that the same grip is held whether said portable light is a lantern or a flash light. It is also preferable that when one end of said handle remains secured and said other end is movable, said other end is secured to a movable part of said light to prevent same from moving into the lantern mode.
  • Fig. 1 illustrates a portable light and its handle assembly in flashlight mode
  • Fig. 2 illustrates a portable light and its handle assembly in lantern mode
  • Fig. 3 illustrates a plan view over the handle assembly illustrated in Fig. 2;
  • Fig. 4 illustrates a side view of the apparatus of Fig. 2.
  • a portable light 1 comprises a body 2, lens assembly 3 at one end, lantern portions 4, and handle assembly 5.
  • the portable light 1 When the portable light 1 is as illustrated in Fig. 1 the portable light is in flash light mode and the lantern portion 4 is concealed.
  • the light globe 6 is placed at the focal point of the parabolic reflector (not illustrated) in the flash light lens assembly 3.
  • the body 2 When moved to a lantern mode the body 2 is relatively moved away from the lens assembly 3 to expose the globe 6 to the lantern portion 4 thus preventing a substantial amount of light from being passed through the lens assembly 3 and directing the light in a radial fashion away from the light globe 6.
  • the end 7 of handle assembly 5 is secured in place on the rear 10 of the body 2 into a recess which allows the end 7 of the handle assembly 5 to rotate relative to the body 2, when end 8 is unsecured.
  • the end 7 is secured at an angle to both the rear 10 and side 12 of the body 2, as best depicted in Fig. 2.
  • the end 7 is depicted as being in the same plane as side 12, however, in practice it sits at approximately the same angle as depicted in Figs. 2 and 4, when the handle assembly 5 is in flashlight mode.
  • the other end 8 is removably secured to the opposite portion on body 2 as compared with the location of end 7. Any releasable securing means can be utilised however a bayonet type fitting is most preferred.
  • the bayonet fitting (not illustrated) engages a recess 9 (preferably sealed) in the body of the light 2.
  • the lens assembly 3 and lantern portion 4 must be slid back into the body 2 because the length of the handle assembly 5 is selected so as to maintain the portable light 1 in flash light mode when the end 8 of handle assembly 5 is inserted into the sealed recess 9.
  • the handle assembly 5 In this manner to convert the portable light 1 into lantern mode, the handle assembly 5 must also be put into the corresponding lantern mode i.e. both ends 7 and 8 must be located on the top or rear surface 10 of the body 2. The engagement of recess 9 by end 8 prevents the conversion to lantern mode.
  • the handle assembly 5, can also be used as a control to focus the beam of light, as an amount of sliding movement of the lens assembly 3 is still possible.
  • the lens assembly 3 can move away from the body 2 to change the point of emission of light from the light globe 6 relative to the focal point of the parabola. In this way focussing can be affected.
  • the switching means is located at the rear or top portion 10 of the body 2.
  • the handle assembly 5 When the handle assembly 5 is in lantern mode, the user, by virtue of the relative strength and stiffness of the handle can utilise the light as a flashlight, that is the lens assembly 3 being fully retracted. This gives the user the freedom to chose the best grip arrangement for any desired lighting requirement.
  • the handle assembly 5, as depicted in Fig. 3 illustrates that the grip portion 15 has a series of grooves 16 extending transversely across the handle assembly 5. It will also be noted that the grip portion 15 has convex sides 17, which when gripped by a user provides a positive grip. When the portable light is used as a flashlight, but with the handle in the lantern configuration, the convex sides 17 of the grip portion 15 allows the user to counter act the rotational force produced by gravity.
  • the handle assembly 5 is constructed from a single moulding, except for the bayonet fitting which is attached later.
  • the grip portion 15, is generally thicker than the portions 13 which lie between the grip portion 15 and the ends 7 and 8. In being thicker, the grip portion 15 would be less flexible than the portions 13, but the addition of grooves 16 restores some of this flexibility.
  • the bayonet fitting is secured into a recess in the end 8.
  • the bayonet fitting because of its different functional requirements, is manufactured from a less flexible plastics material than the portions 13 and 15.
  • the switching mechanism is located to one side of the handle means 5.
  • the handle means 5 is constructed such that the ends 7 and 8 maintain their relative positions on a handle carriage, on which carriage the handle assembly 5 slides from the rear or upper portion 10 of body 2 onto the side portions of the body 2. In this manner the handle assembly does not disconnect but rather moves as a whole from the lantern orientation to the flash light orientation. In the respective arrangements the handle carriage can be locked in place.
  • both ends 7 and 8 are releasably securable to the body.
  • Such securings as press studs, bayonet fittings or the like can be utilised.

Abstract

Ensemble poignée pour torche portable, cette dernière pouvant passer d'un mode projecteur à un mode lanterne et réciproquement, l'ensemble poignée comprenant un système de poignée dont les extrémités pénètrent dans le corps de la lampe. L'invention se caractérise par le fait qu'une partie ou la totalité de ce système de poignée peut passer d'une première configuration dans laquelle cette poignée permet de tenir la torche comme un projecteur à une deuxième configuration dans laquelle on peut tenir la torche comme une lanterne.
