Description

  The present invention relates to a portable light, and more particularly to a light with improved usability.

  Conventionally, there is a battery type light as a portable light used outdoors. In this battery-type light, a dry battery is incorporated, and a light source such as an LED is turned on by turning on / off the switch. However, if the battery runs out, it can no longer be used. For example, when you use a light for a long time in a coal mine or when it remains unused for a long time in preparation for a major earthquake, Light is not preferred.

  Therefore, there is a charging light equipped with a manual generator, charger, etc. (see, for example, Patent Document 1). The light disclosed in Patent Document 1 includes a generator, a charger, an LED, and the like. Then, the charger can be charged with electricity by manually rotating the handle and rotating the rotor of the generator. Thereby, even if it is a case where the electricity of a charger discharges, if a handle | steering wheel is rotated as needed, LED can be lighted.

  However, in view of the recent demand for compactness (compact storage) of the entire light, it is difficult to say that the light disclosed in Patent Document 1 satisfies this requirement. Specifically, since the axial direction of the rotating shaft of the handle and the irradiation direction of the LED are the same, the total length of the light is inevitably increased when the light is stored in a box or the like. From such a request, there is a charging light in which the axial direction of the rotation axis of the handle and the irradiation direction of the LED are orthogonal to each other (see, for example, Patent Document 2). In the charging light disclosed in Patent Document 2, the axial direction of the rotation axis of the handle and the irradiation direction of the LED are orthogonal to each other, so that the total length of the light is shorter than the light of Patent Document 1.

  Therefore, according to the charging light disclosed in Patent Document 2, no battery is required, and the LED can be turned on as needed, and in addition, compact storage can be realized.

JP 2000-90704 A (FIG. 1) Japanese Patent Laying-Open No. 2003-257201 (FIG. 1)

  However, the charging light disclosed in Patent Document 2 is assumed to be used by being held by hand, and is not assumed to be used by being attached to something such as a helmet or a bicycle. That is, when this charging light is considered as one attachment component, a complicated structure such as a holding portion for sandwiching the charging light is required on the main body to be attached.

  In addition, the charging light disclosed in Patent Document 2 is more compact than the light disclosed in Patent Document 1, but the grip portion of the handle is always in a protruding state. There is room for improvement.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a light that can be easily attached and contributes to compactness when considered as an attachment part.

  In order to solve the above problems, the present invention provides the following.

  (1) A generator that generates electric power by rotating a rotor, a charger that charges current generated by the generator, and a direction of a rotation axis of the rotor by current discharged from the charger A light source that lights in a direction substantially orthogonal to the generator, a housing that fixes the generator, the charger, and the light source, and a light that includes a handle coupled to the rotor, the handle includes: An engagement hole that engages with a protrusion formed on an arbitrary object is formed, and the handle and the housing are configured to be bendable by a longitudinal hinge portion. Light.

  According to the present invention, in a light having a generator, a charger, a light source, and a housing and having a handle coupled to a rotor of the generator, the handle is formed on an arbitrary object. Since the engagement hole that engages with the protrusion is formed, and the handle and the housing are configured to be bendable by the longitudinal hinge portion, the usability can be improved.

  That is, when the light according to the present invention is considered as an attachment part to be attached to an arbitrary object, as long as the arbitrary object has a protrusion, it can be attached simply by fitting the protrusion into the engagement hole formed in the handle. Is completed. Therefore, attachment becomes easy and by extension, usability can be improved. In addition, when the light is not used (for example, stored in a box), the handle can be bent through the hinge portion so that the grip portion of the handle can be prevented from popping out, which contributes to downsizing. it can.

  (2) The light, wherein the housing is formed with a recess in which a grip portion of the handle is embedded.

  According to the present invention, since the housing described above is formed with a recess in which the grip portion of the handle is embedded, when the handle is bent via the hinge portion, the grip portion of the handle (partly) (Or all) can be embedded in the recesses, and thus further compactness can be realized.

  (3) The light characterized in that the engagement hole is formed in a substantially gourd shape.

  According to the present invention, since the engagement hole described above is formed so as to have a roughly gourd shape, when attaching a light to an arbitrary object, the light is slid in the optical axis direction of the light source and fixed. As a result, stability when attached to an arbitrary object can be improved (light wobble can be prevented).

  (4) The light characterized in that the housing is provided with an insertion hole into which another protrusion formed on an arbitrary object is inserted, and an optical axis direction of the light source is a depth direction.

  According to the present invention, the housing described above is provided with an insertion hole in which another protrusion formed on an arbitrary object is inserted and the optical axis direction of the light source is the depth direction. By inserting other protrusions into the insertion hole, the stability when attached to any object can be further improved. (By preventing the handle from being bent through the hinge part, the light will wobble. Can be prevented).

  As described above, the present invention can be easily mounted when the light is considered as a mounting part, and the entire light can be stored in a compact manner, so that the usability can be improved.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view showing an appearance of a light 1 according to an embodiment of the present invention. 2 is a plan view of the light 1 shown in FIG. 1, FIG. 3 is a side view of the light 1 shown in FIG. 1, and FIG. 4 is a front view of the light 1 shown in FIG. FIG. 5 is a bottom view of the light 1 shown in FIG. Note that the light 1 according to the present embodiment includes a generator that generates power by rotating the rotor and a charger that charges current generated by the generator. For convenience, the generator and the charger are not shown.

  1 to 5, the light 1 according to the present embodiment includes an LED 10, an upper cover 11, a lower cover 12, a switch 13, and a handle 14. The LED 10 is a light source that is turned on by a current discharged from a charger, and is a direction (rightward in FIG. 3) that is approximately orthogonal to the direction of the rotation axis of the rotor (vertical direction in FIG. 3). ). In the present embodiment, an LED is used as an example of a light source, but other light sources may be used. Further, a protective cover is provided in front of the LED 10 to prevent dust and pride from adhering to the surface of the LED 10 and reducing the amount of light.

  The upper cover 11 and the lower cover 12 are fixed by screws or the like, and function as an example of a housing that fixes the generator, the charger, and the LED 10. The upper cover 11 of the housing is provided with a switch 13 for controlling ON / OFF of the LED 10, and the LED 10 can be turned on by pressing the switch 13.

  On the other hand, as shown in FIGS. 3 and 5, a handle 14 is attached to the lower cover 12 of the housing via a hinge portion 15. The hinge portion 15 is configured to bend the handle 14 and the lower cover 12, and has a vertical axis. The grip portion 14 a of the handle 14 is a portion that a person picks when charging the light 1, and is rotatably attached to the vicinity of the tip of the handle 14.

  FIG. 6 is an explanatory diagram for explaining how the light 1 is charged.

  As shown in FIG. 6, when charging the light 1, the grip portion 14a of the handle 14 is picked and the handle 14 is rotated in a predetermined direction (clockwise direction in FIG. 6). Thereby, the light 1 can be charged.

  Here, a mechanism (an example) of charging will be briefly described. In addition to the generator and the charger, a gear box composed of a plurality of gears is provided in the housing of the light 1, and mechanical energy generated by the rotation of the handle 14 is rotated by the generator through the gears. (Of course, the rotating shaft of the handle 14 and the rotor may be directly connected without using a gear). A coil is provided on the rotor of the generator (which constitutes a rotor), a permanent magnet is provided around the rotor (which constitutes a stator), and the rotor rotates in the magnetic field of the permanent magnet. As a result, an induced electromotive force (alternating current) is generated in the coil. In this way, mechanical energy generated by the rotation of the handle 14 is converted into electrical energy. An alternating current generated in the generator is converted into a direct current through an electric element such as a diode and charged in a charger. In addition, what kind of charger may be used. For example, an electric field capacitor, a film capacitor, a multilayer ceramic capacitor, etc. are mentioned.

  Here, in the light 1 according to this embodiment, the handle 14 is formed with an engagement hole 14b that engages with a protrusion formed on an arbitrary object. Specifically, as shown in FIGS. 1 to 5, an engagement hole 14 b is formed near the tip of the handle 14 so as to have a generally gourd shape. With this engagement hole 14b, the light 1 can be easily attached to a connector 21 (see FIG. 10) described later. The details of how the light 1 is attached to the connector 21 will be described later. Further, the shape of the engagement hole 14b is not limited in any manner.

  In the light 1 according to the present embodiment, the handle 14 and the lower cover 12 can be bent via the hinge portion 15 as described above. FIG. 7 is a diagram illustrating a state in which the handle 14 is bent with respect to the lower cover 12. As shown in FIG. 7 (a) → FIG. 7 (b) → FIG. 7 (c), the handle 14 can be rotated in a predetermined direction (FIG. 7 is a clockwise direction) and can be bent easily. Then, the handle 14 can be stored in the lower cover 12 as shown in FIG.

  FIG. 8 is a bottom view showing a state when the handle 14 is stored in the lower cover 12, and FIG. 9 is a rear view showing a state when the handle 14 is stored in the lower cover 12.

  As shown in FIGS. 5, 8 and 9, when the handle 14 is stored in the lower cover 12, the grip portion 14 a of the handle 14 is embedded in a recess 12 a (see FIG. 5) formed in the lower cover 12. It has become. As a result, the grip portion 14a of the handle 14 is housed in a state that does not protrude outward.

  Further, as shown in FIG. 9, the recess 12 is formed with two ribs 12b, and an insertion hole 12c is formed by these ribs 12b. The insertion hole 12 c is a hole into which another protrusion formed on an arbitrary object is inserted, and the depth direction thereof is the optical axis direction of the LED 10. In the present embodiment, as an arbitrary object referred to here, a connecting member shown in FIG. 10 will be described as an example.

  FIG. 10 is a perspective view showing the appearance of the connecting member 21 for attaching the light 1.

  In FIG. 10, the connecting member 21 is formed with a first protrusion 21a as a protrusion that engages with the engagement hole 14b, and a second protrusion 21b as a protrusion that is inserted into the insertion hole 12c. . A band 22 is attached to the connecting member 21.

  FIG. 11 is an explanatory diagram for explaining how the light 1 is attached to the connecting member 21.

  First, as shown to Fig.11 (a), the light 11 is moved to the direction of the arrow in a figure, and the 1st projection part 21a is inserted in the engagement hole 14b (refer FIG. 8). Next, as shown in FIG. 11B, the light 11 is moved in the direction of the arrow in the drawing, and the second protrusion 21b is inserted into the insertion hole 12c (see FIG. 9). As a result, the attachment is completed as shown in FIG.

  At this time, in the gourd-shaped engagement hole 14b, the first protrusion 21a moves from the wide area to the narrow area (in FIG. 8, the first protrusion 21a is included in the engagement hole 14b. The first protrusion 21a engages with the engagement hole 14b. At the same time, the light 1 is fixed to the second protrusion 21b by the rib 12b (see FIG. 9) formed inside the recess 12a (see FIG. 5). As a result, the lower cover 12 moves away from the handle 14 (in FIG. 11C, the lower cover 12 of the light 1 rotates clockwise and the lower cover 12 moves away from the handle 14). As a result, the light 1 can be reliably fixed by the connecting member 21.

  FIG. 12 is a view showing a state when the light 1 is attached to the helmet 30 via the connecting member 21 and the band 22. For example, when using a light for a long time in a coal mine or the like, the worker puts on the helmet 30 and presses the switch 13 to turn on the LED 10. Thereafter, when the LED 10 is turned off due to power shortage, the worker takes off the helmet 30, removes the light 1 from the connecting member 21, and turns the handle 14 to perform charging. When the charging is completed, the light 1 is attached to the connecting member 21 again (see FIG. 11), and the operation is resumed.

  Thus, since the light 1 according to the present embodiment is easy to attach and remove, the light use-charge-light use cycle can be easily performed. Therefore, it is easy to use.

  As described above, according to the light 1 according to the present embodiment, as long as the connecting member 21 has the first protrusion 21a, the first protrusion 21a is fitted into the engagement hole 14b formed in the handle 14. Installation is completed just by inserting. Moreover, as described above, the light 1 can be prevented from wobbling by inserting the second protrusion 21 b of the connecting member 21 into the insertion hole 12 c formed in the handle 14. Thus, it is easy to attach and can be firmly fixed to an arbitrary object (for example, the connecting member 21), so that the usability can be improved.

  Further, when the light is not used (for example, stored in a box) or when the light is used (attached to the helmet 30), the handle 14 is bent via the hinge portion 15 so that the grip portion 14a of the handle 14 is recessed. By storing (embedding) in 12a, the grip portion 14a of the handle 14 can be prevented from popping out (see FIG. 7), which can contribute to downsizing.

  Furthermore, in this embodiment, since the engagement hole 14b has a gourd shape, when the light 1 is attached to the connecting member 21, it can be firmly fixed, and thus wobble of the light can be prevented. .

  In addition, although the example which attaches the light 1 to the helmet 30 was shown in this embodiment, you may use as a headlight of a bicycle or a motorbike, for example, or as a monitoring light of a warehouse.

  The light according to the present invention is useful as a light that can be easily attached to an arbitrary object and can improve usability.
