Description

  The present invention relates to a lantern, and more particularly to a lantern that can easily change the direction of light.

  FIG. 7 shows a lantern 100 disclosed in Patent Document 1, in which an upper guide 105 and a lower guide 106 are installed around a light source unit 120, and a hook 115 is attached to a reflector 110. The reflector 110 can be attached around the light source unit 120 by engaging the 106.

Japanese Patent Laid-Open No. 3-190001

 However, in the above configuration, when the direction of light is changed in a state where the lantern 100 is suspended, the reflector 110 must be directly held by a finger to adjust the engagement position between the hook 115 and the guides 105 and 106, The vessel 110 was sometimes hot. In addition, the hook 115 and the guides 105 and 106 can be engaged anywhere around the light source unit 120. However, since the reflector 110 is rotated against the engagement force between the hook 115 and the guides 105 and 106, the click feeling is reduced. Some good operability could not be obtained.

  The present invention solves the above-described problems, and provides a lantern that can easily change the direction of light with a simple operation and can provide a good operability with a click feeling.

In order to achieve the above object, a lantern according to the present invention includes a reflector that reflects light from a light source, a holder to which the light source and the reflector are attached, a housing that fixes and supports the holder, and a suspension. In a lantern comprising a handle that can be used as illumination in a lowered state, the handle is attached to a ring member that is mounted on the outer periphery of the housing , and the housing is attached to the ring member in a suspended state. Thus, it is configured to be rotatable around the vertical axis . Further, recesses are provided at substantially equal intervals on the inner periphery of the ring member, and a leaf spring is provided on a part of the outer periphery of the housing to engage with the recesses. A click feeling is generated when engaged with the leaf spring .

  According to the present invention, the direction of light can be easily changed by a simple operation. Further, when adjusting the direction of light, good operability with a click feeling can be obtained as the housing rotates.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments for carrying out the invention will be described with reference to the drawings.

  1 and 2, 2 is a handle for hanging or carrying the lantern 1, 3 is a light source unit of the lantern 1, 4 is a control unit for controlling dimming of the light source unit 3, and 5 is a battery. The handle 2 is pivotally supported by a ring member 7 mounted around the control unit 4 by a handle shaft portion 21 so as to be rotatable.

  3 to 6, reference numeral 31 denotes a fluorescent lamp as a light source of the lantern 1, 32 denotes a reflecting plate that reflects light from the fluorescent lamp 31, and 33 denotes a transparent lamp that houses and protects the fluorescent lamp 31 and the reflecting plate 32 inside. This is a plastic cup-shaped cover. The light source unit 3 is mainly configured by a fluorescent lamp 31, a reflecting plate 32, and a cover 33. The lower end of the fluorescent lamp 31 passes through a hole (not shown) formed in the center of the substantially cylindrical holder 41, and is inserted into and fixed to a fluorescent lamp socket 42 mounted on the main board 43. The portion is fixed to the cover 33 with a buffer rubber 34. The main board 43 is an electronic circuit board that controls the dimming of the fluorescent lamp 31, and is fixed to the lower surface of the holder 41 with a bolt or the like (not shown). Reference numeral 44 denotes a housing, and the housing 44 is assembled by fastening the two housing parts 44a and 44b with bolts or the like. Inside the housing 44, a holder 41 is fixed and accommodated in the housing 44. The control unit 4 is mainly configured by a holder 41, a fluorescent lamp socket 42, a main board 43, and a housing 44. The outer periphery near the opening of the cover 33 is formed in a convex shape, and a screw is cut on the outer periphery from the wall 33 a on the convex opening side to the opening, and is screwed to a screw formed on the inner surface of the housing 44. Thus, the cover 33 is attached to the housing 44. The outer periphery around the center of the housing 44 is also convex, and a wall 44c is provided on the cover 33 side. The ring member 7 is appropriately sandwiched between the walls 33a and 44c. It is mounted so as to be rotatable around the housing 44 without moving in the direction). A part of the housing part 44a is formed in a recessed shape so that the leaf spring 6 can be attached and the leaf spring 6 can be expanded and contracted. The leaf spring 6 is substantially arcuate and has a projection 6a formed in the center. The projection 6a is urged in a direction to engage with recesses 7a formed on the inner periphery of the ring member 7 at substantially equal intervals. Both sides of the ring member 7 are structured to support the handle shaft 21. Reference numeral 8 denotes a switch for operating the light control of the light source unit 3.

  When the lantern 1 configured as described above is suspended at an appropriate place and the switch 8 is operated to cause the fluorescent lamp 31 to emit light, the light from the lantern 1 is strongly irradiated in the direction reflected by the reflector 32. When the user wants to slightly change the direction of light emitted from the lantern 1, the user only needs to hold the neck portion 44d of the housing 44 or the battery 5 and rotate it in a desired direction. At this time, the protrusion 6 a of the leaf spring 6 is disengaged from the recess 7 a formed on the inner periphery of the ring member 7, and moves to the adjacent recess 7 a while contacting the inner peripheral wall 7 b of the ring member 7. When the protrusion 6a of the leaf spring 6 is engaged with the adjacent recess 7a, the user can feel a comfortable click feeling and realize that the direction of the irradiation light has changed.

  The lantern 1 according to the present invention is not limited to the embodiments described above, and various modifications and improvements can be made within the scope described in the claims.

  This invention is useful for lanthanum.
