  In the fire-floodlight projector according to the embodiment of the present invention, since at least one through hole is formed in the handle, the carabiner can be carried by passing the carabiner through the through hole. According to the embodiment of the present invention, since it is not necessary to separately attach a member for passing the carabiner to the housing, it is possible to reduce the number of parts and reduce the weight of the projector. Furthermore, since the handle itself is made lighter by forming the through hole in the handle, it is possible to obtain the effect of making the entire projector lighter. Also, when the carabiner is passed through the through hole formed in the handle, it is possible to prevent the carabiner from slipping (displacement), which is the case when the carabiner is passed between the handle and the housing. The posture of the projector can be stabilized. Further, in the fire fighting light projector according to the embodiment of the present invention, the through hole of the handle is located between the center of gravity of the light projector and the rear end of the handle in the front-back direction of the light projector. That is, the through hole of the handle is located behind the center of gravity of the projector. As a result, it is possible to prevent the light source unit from facing obliquely upward when carrying the carabiner. When the light source unit faces obliquely upward, there is a risk that the face of a person will be irradiated with light. As described above, according to the embodiment of the present invention, it is possible to obtain the floodlight for fire fighting, which has the structure suitable for carrying using the carabiner and can realize the weight reduction.

  When the number of through holes in the handle is plural, the attitude (tilt) of the projector when carrying the carabiner can be adjusted (selected).

  From the viewpoint of ease of manufacturing, the number of through holes in the handle is preferably 2.

  From the viewpoint of directing the light source section in a direction close to the horizontal direction, it is preferable that at least one through hole formed in the handle includes a through hole arranged at a position as close to the center of gravity of the projector as possible. Preferably includes a first through hole located within the range of ⅔ of the length of the projector from the front end of the projector in the front-back direction of the projector.

  From the viewpoint of widening the adjustment range of the attitude of the projector when carrying, at least one through hole formed in the handle is within a range of 1/3 of the length of the projector from the rear end of the projector in the front-back direction of the projector. It is preferable to further include a second through hole located at.

  The central axis of at least one through hole may be oriented in the left-right direction of the floodlight or may be oriented in the up-down direction of the floodlight.

  At least one through hole may include a through hole having a substantially circular shape when viewed from the central axis direction.

  Since the diameter of the carabiner for fire fighting is, for example, 10 mm, if the diameter of the through hole is 14 mm or more, the carabiner can be suitably passed through the through hole.

  By including at least one through hole that is a long hole, it is possible to further reduce the weight of the handle and the floodlight.

  Since the diameter of the carabiner for fire fighting is, for example, 10 mm, the short diameter of the through hole, which is a long hole, is preferably 14 mm or more.

  Further, in a carabiner for fire fighting, the opening width of the gate portion is, for example, about 34 mm. Therefore, the thickness of the handle along the central axis direction of the through hole is preferably 24 mm or less.

  According to the embodiment of the present invention, it is possible to provide a fire fighting floodlight that has a structure suitable for carrying using a carabiner and that can realize weight reduction.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments below.

(Embodiment 1)
With reference to FIGS. 1 to 4, a fire fighting light projector (hereinafter simply referred to as “light projector”) 100 according to the present embodiment will be described. 1, FIG. 2, FIG. 3 and FIG. 4 are a perspective view, a front view, a side view and a top view schematically showing the projector 100, respectively.

  As shown in FIGS. 1 to 4, the floodlight 100 includes a light source unit 10, a housing 20, and a handle 30. The projector 100 further includes a first switch 40, a second switch 50, and a signal indicator lamp 60. The projector 100 is connected to a signal device described later via a connection cable 1. The floodlight 100 can be carried while holding the handle 30 with one hand. Further, the floodlight 100 can be carried using a carabiner (for example, carried in a state in which the carabiner is held on the waist of the user), as described later.

  The light source unit (light source unit) 10 includes a plurality of LED (light emitting diode) elements 11 (see FIGS. 5 to 8 described later) as a light source. The light source unit 10 can switch between a state in which light is condensed and emitted and a state in which light is diffused and emitted. That is, the light source unit 10 has a configuration capable of switching the light distribution. A more specific configuration of the light source unit 10 will be described later.

  The housing (apparatus body) 20 accommodates the light source unit 10. The housing 20 is preferably formed of a material that is lightweight and has excellent heat resistance. As the material of the housing 20, for example, carbon fiber reinforced plastic (CFRP), glass fiber reinforced plastic (GFRP), metal material (for example, aluminum alloy), or the like can be preferably used. The light source unit 10 is disposed in the front portion of the housing 20, and the front portion (first lens portion and second lens portion described later) of the light source portion 10 is exposed from the housing 20. A protection member (lens guard) 25 for protecting the front part of the light source unit 10 is attached to the front part of the housing 20. The protection member 25 is made of a metal material (for example, titanium alloy or stainless alloy).

  A plurality of notches 21a and 21b are formed on both side surfaces (left side surface and right side surface) of the housing 20, respectively. These notches 21a and 21b function as heat dissipation holes for radiating the heat of the light source unit 10. In the illustrated example, the plurality of cutouts 21a and 21b include a substantially X-shaped first cutout 21a and a plurality of substantially rectangular or trapezoidal second cutouts 21b. Three second notch portions 21b are located above the first notch portion 21a, and two second notch portions 21b are located below the first notch portion 21a.

  The connection cable 1 is connected to the rear part of the housing 20. A tripod attachment boss 26 and a support member 27 are attached to the lower portion of the housing 20. As described above, the floodlight 100 can be used while being carried, but by attaching the tripod to the tripod mounting boss 26, the floodlight 100 can be used while being placed at a desired height above the ground. The support member 27 is provided such that the optical axis of the light source unit 10 is substantially horizontal (that is, light is emitted substantially horizontally) when the projector 100 is placed on the ground. A box-shaped portion (hereinafter referred to as “box portion”) 20a is formed on the front side of the upper portion of the housing 20. A convex portion 20b extending rearward and slightly downward from the box portion 20a is formed. A buzzer 28 is arranged on the upper rear side of the housing 20. Although not shown here, a control board for controlling the current supplied to the light source unit 10 is arranged behind the light source unit 10 inside the housing 20.

  As shown in FIG. 4, the housing 20 has a portion WR that is wider in the left-right direction than other portions of the housing 20. Hereinafter, this portion WR is referred to as a “wide portion”, and the portion NR of the housing 20 other than the wide portion WR is referred to as a “narrow portion”. That is, the housing 20 has the wide portion WR having a relatively large width in the left-right direction and the narrow portion NR having a relatively small width in the left-right direction.

  Further, each of both side surfaces of the housing 20 includes a curved surface portion GP which is recessed inward in the left-right direction. The curved surface portion GP will be described in detail later.

  The handle 30 is arranged on the upper part of the housing 20. The handle 30 is gripped by the user's hand. As shown in FIG. 4, in a plan view (top view), the longitudinal direction of the handle 30 faces the front-back direction of the projector 100. Further, as shown in FIG. 3, the handle 30 extends rearward and slightly downward from the convex portion 20b in a side view. The handle 30 is made of a metal material (for example, an aluminum alloy) or a resin material (for example, polyacetal or nylon 66). The convex portion 20b of the housing 20 is inserted into the front end of the handle 30. The rear end of the handle 30 is fixed to the rear part of the housing 20 via a bracket 29. The bracket 29 is made of a metal material such as CFRP, titanium alloy, or stainless alloy.

  The handle 30 has a columnar shape. In the illustrated example, the handle 30 has a first flat surface 30a and a second flat surface 30b, and a first curved surface 30c and a second curved surface 30d as side surfaces. The first plane 30a and the second plane 30b face each other. The first curved surface 30c and the second curved surface 30d face each other. The first curved surface 30c and the second curved surface 30d connect the first plane 30a and the second plane 30b, respectively. In the illustrated example, the handle 30 is arranged such that the first plane 30a and the second plane 30b face the left-right direction of the projector 100.

  The first switch 40 receives an operation of transmitting a signal to the signal device via the connection cable 1. On the other hand, the second switch 50 receives an operation of switching the light distribution of the light source unit 10. Below, the 1st switch 40 may be called a "signal switch", and the 2nd switch 50 may be called a "light distribution switch."

  In the illustrated example, each of the first switch 40 and the second switch 50 is a so-called push button switch. Needless to say, the first switch 40 and the second switch 50 are not limited to push button switches. For example, the first switch 40 and the second switch 50 may be tactile switches, rocker switches or toggle switches.

  The signal indicator lamp 60 lights up in response to the transmission of a signal to the traffic light. Typically, the signal indicator lamp 60 lights up in synchronization with signal transmission. In the illustrated example, the buzzer 28 also operates in response to the transmission of the signal to the signal device. That is, the buzzer 28 emits a buzzer sound (typically in synchronization) in response to the signal transmission.

  A specific configuration of the light source unit 10 will be described with reference to FIGS. 5 to 8. 5, FIG. 6, FIG. 7 and FIG. 8 are a perspective view, a front view, a side view and a top view schematically showing the light source unit 10, respectively.

  As shown in FIGS. 5 to 8, the light source unit 10 has a plurality of LED elements 11, a first lens unit 12, a second lens unit 13, and a heat sink unit 14.

  As shown in FIG. 6, the plurality of LED elements 11 include a plurality of (here, six) first LED elements 11a located relatively outside and a plurality of LED elements located relatively inside when viewed from the front direction. (Here, six) second LED elements 11b are included. The number and arrangement of the first LED element 11a and the second LED element 11b are not limited to the illustrated example.

  The first lens unit 12 includes a plurality of lenses (first lenses) 12a arranged at positions corresponding to the plurality of first LED elements 11a. The second lens unit 13 includes a plurality of lenses (second lenses) 13a arranged at positions corresponding to the plurality of second LED elements 11b. The first lens portion 12 and the second lens portion 13 are each made of a resin material or a glass material.

  The heat sink portion 14 has a base portion 14a and a plurality of fins 14b. The base portion 14a is connected to the first lens portion 12 and the second lens portion 13. The plurality of fins 14b (here, 10) extend rearward from the base portion 14a. The heat sink portion 14 is formed of a metal material (for example, aluminum alloy). The number, arrangement, shape, etc. of the fins 14b are not limited to the illustrated example.

  The light emitted by each LED element 11 is given a desired directivity by the corresponding lens (first lens 12a or second lens 13a). In the illustrated light source unit 10, the focal length of the first lens 12a and the focal length of the second lens 13a are different. By operating the second switch 50, it is possible to switch between the state in which only the first LED element 11a is lit and the state in which only the second LED element 11b is lit, so that the light distribution of the light source unit 10 can be switched. it can. The focal lengths of the first lens 12a and the second lens 13a are such that the state in which only the first LED element 11a is turned on is the condensed irradiation state, and the state in which only the second LED element 11b is turned on is the diffuse reflection state. It may be set or vice versa.

  The first LED element 11a and the second LED element 11b may have the same emission color or different emission colors. If the emission color of the first LED element 11a and the emission color of the second LED element 11b are different, the emission color of the light source unit 10 can also be switched when switching the light distribution. As a configuration in which the emission color of the first LED element 11a and the emission color of the second LED element 11b are different, for example, one emission color of the first LED element 11a and the second LED element 11b is white and the other emission color is yellow. A configuration can be adopted. In a space filled with smoke, visibility is different depending on the emission color (for example, yellow light has higher visibility than white light). Therefore, by switching the emission color of the light source unit 10, workability can be improved. Further improvement can be aimed at.

  An example of the signal device will be described with reference to FIG. 9. FIG. 9 is a side view schematically showing the signal device 200.

  The signal device 200 shown in FIG. 9 is connected to the projector 100 via the connection cable 1. Further, the signal device 200 is connected to a commercial power source or a generator via another connection cable 2. Therefore, it can be said that the projector 100 is supplied with power from the external power source (commercial power source or generator) via the signal device 200. By supplying power from an external power source, the projector 100 can be used for a long time (a desired time required for fire fighting activities).

  The signal device 200 includes a signal device body 201, a handle 202, a third switch (signal switch) 203, a signal indicator lamp 204, a buzzer 205, and a power supply unit 206.

  The signal device main body 201 houses the buzzer 205 and the power supply unit 206 therein. A handle 202 is provided on the top of the signal device body 201.

  The third switch 203 receives an operation of transmitting a signal to the projector 100 via the connection cable 1. In the illustrated example, the third switch 203 is arranged above the signal device body 201.

  The signal indicator lamp 204 lights up in response to the transmission of a signal to the projector 100. Typically, the signal indicator lamp 204 lights up in synchronization with the transmission of the signal. In the illustrated example, the buzzer 205 also operates in response to the transmission of the signal to the projector 100. That is, the buzzer 205 emits a buzzer sound (typically in synchronization) in response to the signal transmission.

  The power supply unit 206 performs rectification, step-up, step-down, or the like on current/voltage supplied from a commercial power source or a generator, as needed.

  Here, the configuration of the projector 100 according to the present embodiment will be described with reference to FIGS. 1 to 4 and 10 again.

  At least one through hole 31 is formed in the handle 30 of the light projector 100, as shown in FIG. In this embodiment, the number of the through holes 31 is plural, and more specifically, two. The two through holes 31 penetrate the handle 30 from the first plane 30a side to the second plane 30b side (also referred to as the second plane 30b side to the first plane 30a side). Therefore, the depth direction of the through hole 31 is oriented in the left-right direction of the projector 100, in other words, the central axis of the through hole 31 (see FIG. 1) is oriented in the left-right direction of the projector 100. In the illustrated example, the central axis of the through hole 31 is substantially parallel to the lateral direction of the projector 100. The shape of the through hole 31 when viewed from the central axis direction (depth direction) is substantially circular.

  FIG. 10 shows the position of the center of gravity of the projector 100. In FIG. 10, the chain line CG indicates the position of the center of gravity in the front-back direction. As can be seen from FIG. 10, the center of gravity of the projector 100 is located in front of the center in the front-rear direction (that is, on the light source unit 10 side). The two through holes 31 are located between the center of gravity of the light projector 100 and the rear end of the handle 30 in the front-back direction of the light projector 100.

  A chain line CH in FIG. 10 indicates a position separated from the front end of the projector 100 by ⅔ of the entire length of the projector 100. That is, the chain line CH indicates the boundary between the range of 2/3 from the front end of the projector 100 and the remaining range, that is, the range of 1/3 from the rear end of the projector 100.

  As shown in FIG. 10, of the two through holes 31, the first through hole 31A located relatively on the front side is behind the center of gravity of the light projector 100 in the front-back direction of the light projector 100 and of the light projector 100. It is located within 2/3 of the front edge. Further, the second through hole 31B located relatively on the rear side is located behind the center of gravity of the projector 100 in the front-back direction of the projector 100 and within a range of 1/3 from the rear end of the projector 100. ing.

  The through hole 31 described above is a hole for passing the carabiner. Therefore, the through hole 31 has a diameter larger than the diameter of the carabiner used. An example of a carabiner is shown in FIGS. 11(a), (b) and (c). FIG. 11A is a plan view showing the carabiner 300. 11B and 11C are views of the carabiner 300 viewed from directions D1 and D2 in FIG. 11A, respectively.

  The outer shape of the entire carabiner 300 is annular, and more specifically, it is substantially O-shaped. The carabiner 300 is made of a metal material. The carabiner 300 includes a main body 301 and a gate 302 that is attached to the main body 301 so as to be openable and closable. In the illustrated example, the gate portion 302 is a screw lock type.

  FIG. 12 shows an example of a state in which the carabiner 300 is passed through the through hole 31 of the handle 30 of the light projector 100. As shown in FIG. 12, by passing the carabiner 300 through the through hole 31 of the handle 30, it becomes possible to carry the projector 100 using the carabiner 300 (for example, carrying the projector 100 on the user's waist). .. Here, the example in which the carabiner 300 is passed through the first through hole 31A has been described, but the carabiner 300 may be passed through the second through hole 31B.

  As described above, in the floodlight 100 of the present embodiment, at least one through hole 31 is formed in the handle 30, so that the carabiner 300 can be carried by passing the carabiner 300 through the through hole 31. According to the present embodiment, it is not necessary to separately attach a member for passing the carabiner 300 (for example, a metal plate bracket) to the housing 20, so that the number of parts can be reduced and the projector 100 can be made lightweight. You can Further, since the handle 30 itself is lightened by forming the through hole 31 in the handle 30, it is possible to obtain the effect of reducing the weight of the projector 100 as a whole.

  Further, when the carabiner 300 is passed through the through hole 31 formed in the handle 30, it is possible to prevent the carabiner 300 from slipping (shifting) as in the case where the carabiner 300 is passed between the handle 30 and the housing 20. It is possible to stabilize the posture of the projector 100 when carrying the carabiner 300.

  Further, in the present embodiment, the through hole 31 of the handle 30 is located between the center of gravity of the light projector 100 and the rear end of the handle 30 in the front-back direction of the light projector 100. That is, the through hole 31 of the handle 30 is located behind the center of gravity of the projector 100. As a result, it is possible to prevent the light source unit 10 from facing obliquely upward when carrying the carabiner 300. If the light source unit 10 is directed obliquely upward, there is a risk that the face of a person will be irradiated with light. As described above, in the configuration in which the through hole 31 for allowing the carabiner 300 to pass through is provided in the handle 30, there is a certain degree of freedom in the position and the number of the through holes 31, and therefore, there is a balance (light projector) when the projector 100 is held on the waist. The slope of 100) can be adjusted.

  Further, in the present embodiment, the longitudinal direction of the handle 30 is oriented in the front-back direction of the light projector 100 in a plan view. On the other hand, if a configuration is adopted in which the longitudinal direction of the handle faces the left-right direction of the projector, when the projector is hung on the waist using a carabiner, the projector projects too much from the side of the user's body, so in a narrow place. Is not suitable for the behavior of. Since the longitudinal direction of the handle 30 faces the front-back direction of the floodlight 100 as in the present embodiment, the floodlight 100 can be suitably used for firefighting activities and disaster relief in which actions in a narrow space are expected.

  As described above, according to the embodiment of the present invention, it is possible to obtain the floodlight 100 for fire fighting, which has a structure suitable for carrying using the carabiner 300 and can realize weight reduction.

  In addition, when a member for passing the carabiner 300 (for example, the above-described sheet metal bracket) is separately attached to the housing 20, an extra uneven portion is added to the projector 100, and such an uneven portion is formed. , There is a risk of getting caught in things during firefighting activities. According to this embodiment, such an extra uneven portion does not increase. That is, it is possible to reduce the uneven portion of the entire light projector 100. In the illustrated example, the handle 30 does not have a protrusion (protrusion).

  In addition, although the case where the number of the through holes 31 of the handle 30 is plural is illustrated in the present embodiment, the number of the through holes 31 may be one. As illustrated in the present embodiment, when the number of the through holes 31 is plural, the attitude (tilt) of the projector 100 when carrying the carabiner 300 can be adjusted (selected). For example, in the configuration shown in FIG. 1 and the like, of the two through holes 31 formed in the handle 30, the second one located relatively on the rear side (that is, the distance from the center of gravity of the projector 100 is relatively large). When the carabiner 300 is passed through the through-hole 31B, the light source unit is compared with the case where the carabiner 300 is passed through the first through-hole 31A located relatively on the front side (that is, the distance from the center of gravity of the projector 100 is relatively small). It is possible to direct 10 downward (that is, increase the inclination of the projector 100 with respect to the horizontal direction).

  When the handle 30 has a plurality of through holes 31, the number of the through holes 31 is not limited to 2, and may be 3 or more. From the viewpoint of increasing the variation in the adjustment (selection) of the attitude of the light projector 100, it can be said that the number of the through holes 31 is preferably 3 or more, but from the viewpoint of ease of manufacturing, 2 is preferable.

  From the viewpoint of orienting the light source unit 10 in a direction close to the horizontal direction, at least one through hole 31 preferably includes the through hole 31 arranged at a position as close to the center of gravity of the projector 100 as possible, and specifically, As illustrated in the present embodiment, the first penetration located within the range of ⅔ of the length of the projector 100 (more strictly, the length in the front-rear direction) from the front end of the projector 100 in the front-back direction of the projector 100. It is preferable to include the hole 31A. Further, from the viewpoint of increasing the width of adjustment of the posture of the projector 100 when carrying, at least one through hole 31 includes the first through hole 31A arranged in such a position, and the front and rear direction of the projector 100. In, it is preferable to further include a second through hole 31B located within the range of 1/3 of the length of the light projector 100 (more strictly, the length in the front-back direction) from the rear end of the light projector 100.

  The diameter dc (see FIG. 11A) of the carabiner 300 for fire fighting is, for example, 10 mm. When the diameter d of the through hole 31 (see FIG. 12) is 14 mm or more, the carabiner 300 can be suitably passed through the through hole 31.

  In the carabiner 300 for fire fighting, the opening width w of the gate portion 302 (see FIG. 11A) is, for example, about 34 mm. Therefore, the thickness t (see FIG. 4) of the handle 30 along the central axis direction of the through hole 31 is preferably 24 mm or less.

(Embodiment 2)
The projector 100A according to the present embodiment will be described with reference to FIGS. 13 to 15. 13, FIG. 14 and FIG. 15 are a perspective view, a side view and a top view schematically showing the projector 100A, respectively. Hereinafter, the projector 100</b>A will be described focusing on the points different from the projector 100 according to the first embodiment.

  In the projector 100 of the first embodiment, the central axis of the through hole 31 of the handle 30 is oriented in the left-right direction of the projector 100. On the other hand, in the projector 100A of the present embodiment, as shown in FIGS. 13, 14 and 15, the central axis of the through hole 31 of the handle 30 is oriented in the vertical direction of the projector 100A. In the illustrated example, the handle 30 of the floodlight 100A is arranged so that the first plane 30a and the second plane 30b face the up-down direction of the floodlight 100A (that is, the first curved surface 30c and the second curved surface 30d move in the left-right direction of the floodlight 100A). It is arranged so as to face. Therefore, the depth direction of the through hole 31 faces the vertical direction of the light projector 100.

  In addition, "the central axis of the through hole 31 faces the vertical direction of the projector 100A" does not necessarily mean that the central axis of the through hole 31 is strictly parallel to the vertical direction of the projector 100A, It also includes a mode in which the central axis of the through hole 31 is slightly inclined in the front-back direction with respect to the vertical direction of the projector 100A (for example, inclined at an angle of 45° or less, typically 30° or less). ..

  Even when the central axis of the through hole 31 of the handle 30 is oriented in the vertical direction of the projector 100A as in the present embodiment, the carabiner 300 is preferably carried as in the case of the first embodiment. The weight reduction can be realized.

(Embodiment 3)
The projector 100B in the present embodiment will be described with reference to FIGS. 16 and 17. 16 and 17 are a perspective view and a top view schematically showing the projector 100B, respectively. Hereinafter, the projector 100B will be described focusing on the difference from the projector 100A in the second embodiment.

  In the projector 100A of the second embodiment, each of the two through holes 31 of the handle 30 has a substantially circular shape when viewed from the central axis direction. On the other hand, in the projector 100B of the present embodiment, as shown in FIGS. 16 and 17, one of the two through holes 31 (first through hole) 31A of the handle 30 has a shape as viewed from the central axis direction. Is a so-called long hole, which is a shape in which a circle is elongated and elongated.

  As in the present embodiment, at least one through hole 31 includes the through hole 31 that is a long hole, so that the weight of the handle 30 and the projector 100B can be further reduced.

  In addition, here, the configuration in which the first through hole 31A of the two through holes 31 is a long hole is illustrated, but the second through hole 31B may be a long hole instead of the first through hole 31A, Both the first through hole 31A and the second through hole 31B may be elongated holes.

  As described above, since the diameter dc of the carabiner 300 for fire fighting is, for example, 10 mm, the short diameter ds (see FIG. 17) of the first through hole 31A, which is a long hole, is preferably 14 mm or more. When the minor axis ds is 14 mm or more, the carabiner 300 can be suitably passed through the first through hole 31A.

(Locking means provided on the housing)
During firefighting activities, a belt called a safety belt is wrapped around the waist of the fireproof clothing worn by firefighters. The floodlight according to the embodiment of the present invention may further include locking means for locking the housing to a safety belt wrapped around the waist of the user (firefighter). The locking means is provided on at least one of both side surfaces of the housing. The advantages of the provision of the locking means will be described below by taking the projector 100 of the first embodiment shown in FIG. 1 and the like as an example. In the illustrated example, the locking means is the clip portion 22 and is provided on each of both side surfaces of the housing 20. The specific configuration of the clip portion 22 will be described below.

  As shown in FIG. 3, the clip portion 22 has a shape defined by the first cutout portion 21a. Here, the first cutout portion 21a has a substantially X shape. Therefore, the clip portion 22 includes a first tongue piece portion 22a extending downward and a second tongue piece portion 22b extending upward.

  FIG. 18 shows the center position of the projector 100 in the front-rear direction and the position of the center of gravity of the projector 100. In FIG. 18, the chain line CP indicates the center position in the front-rear direction, and the chain line CG indicates the position of the center of gravity in the front-rear direction.

  As can be seen from FIG. 18, the clip portion 22 which is the locking means is located in front of the center of the projector 100 in the front-rear direction. That is, the clip portion 22 is located closer to the center of gravity of the projector 100 than the center of the projector 100 in the front-rear direction. In addition, in FIG. 18, the center position of the clip portion 22 in the front-rear direction is indicated by a chain line 22cp. As can be seen from FIG. 18, “the locking means (clip portion 22) is located closer to the center of gravity of the light projector 100 than the center of the light projector 100 in the front-rear direction” means that the locking means (clip portion 22). This means that the center in the front-rear direction (the position indicated by the chain line 22cp) is located closer to the center of gravity than the center of the projector 100 in the front-rear direction.

  FIG. 19 shows a state in which the housing 20 is locked to the safety belt SB by the clip portion 22. The width and the thickness of the safety band SB are, for example, 50 mm and 2 mm, respectively. As shown in FIG. 19, the safety belt SB is hooked on the first tongue piece portion 22a and the second tongue piece portion 22b of the clip portion 22 (in other words, the back side of the first tongue piece portion 22a and the second tongue piece portion 22b). The housing 20 can be locked to the safety belt SB by passing through the first cutout portion 21a (so that a part of the safety belt SB is located at the bottom). This allows the projector 100 to be fixed to the user's waist while facing forward. At this time, the clip portion 22 locks the housing 20 on the safety belt SB at at least three points. In the illustrated example, the clip portion 22 is locked at three points. More specifically, the first tongue portion 22a is locked at two points and the second tongue portion 22b is locked at one point.

  As described above, the light projector 100 is provided with the locking means (the clip portion 22) for locking the housing 20 on the safety belt SB, and the locking means is the center of gravity of the light projector 100 rather than the center of the light projector 100 in the front-rear direction. Located on the side. Since the locking means is positioned closer to the center of gravity than the center in the front-rear direction, the locking is performed at a position relatively close to the center of gravity, so that the light source unit 10 can be used to hold the projector 100 in a state in which the light source unit 10 faces the front of the user. It becomes easy to fix it to the user's body. On the other hand, if the locking means is located on the side opposite to the center of gravity with respect to the center in the front-rear direction, the distance from the center of gravity of the projector 100 to the locking means may be relatively long, and the light source unit 10 may be It may be difficult to fix the projector 100 to the user's body while facing the front of the user.

  In this way, the floodlight 100 including the locking means can be suitably fixed to the user's body in a state of illuminating the front (that is, with the light source unit 10 facing the front of the user).

  In the illustrated example, the locking means (clip portion 22) is provided on each of both side surfaces of the housing 20, but the locking means is provided on only one of both side surfaces of the housing 20 (the left side surface and the right side surface). Any of the above) may be provided. As illustrated, when the locking means is provided on each of both side surfaces of the housing 20, the projector 100 can be fixed to either the right side or the left side of the user's waist, so that the dominant hand of the user does not matter. Instead, the advantage that the projector 100 can be suitably used is obtained.

  As described above, each of the both side surfaces of the housing 20 includes the curved surface portion GP that is recessed inward in the left-right direction. Since the side surface of the housing 20 on which the locking means is provided includes such a curved surface portion GP, when the housing 20 is locked to the safety belt SB (that is, the projector 100 is fixed), the housing 20 is fixed. It becomes easier to fit the user's body. That is, the curved surface portion GP described above is a portion having a guide shape for the user's body, and is also referred to as a “guide portion” below. Hereinafter, this will be described more specifically with reference to FIGS. 20 and 21. FIG. 20 is a side view of the projector 100, and the guide portion GP is hatched for the sake of clarity. FIG. 21 is a top view of the floodlight 100, and also schematically shows the waist WA of the user.

  In the present embodiment, as shown in FIG. 20, the guide portion GP is located at the central portion in the vertical direction of the side surface of the housing 20, and as shown in FIG. 21, the waist WA of the user (more specifically, Touches the safety belt SB) wrapped around the waist WA.

  Since the side surface of the housing 20 includes such a guide portion GP, the housing 20 easily fits to the user's body when the housing 20 is locked to the safety belt SB. In other words, not only the clip portion 22 but also the guide portion GP comes into contact with the user's body. Therefore, the stability when the projector 100 is fixed is increased. Further, even if the user moves quickly, it is possible to prevent the load from being concentrated only on the clip portion 22, so that the clip portion 22 is less likely to be damaged. Further, since the light projector 100 is supported in a relatively large area, it becomes easier to fix the light source unit 10 with the light source unit 10 facing the front of the user.

  The specific shape of the guide portion GP is set so as to follow the waist of the user as much as possible. The radius of curvature of the guide portion GP is, for example, 250 mm or more and 1300 mm or less.

  Further, in the illustrated configuration, the locking means is the clip portion 22 having a shape defined by the cutout portion 21 a on the side surface of the housing 20. As a result, the number of parts can be reduced, the weight of the housing 20 can be reduced, and the design of the projector 100 can be improved.

  The cutout portion 21a of the housing 20 may function as a heat dissipation hole for radiating heat generated in the light source unit 10. By using the heat dissipation hole also as the cutout portion 21a that defines the shape of the clip portion 22, it is not necessary to form an extra hole in the housing 20.

  Since the clip portion 22 includes the first tongue piece portion 22a extending below the floodlight 100, it becomes easy to lock the floodlight 100 with the safety belt SB extending in the horizontal direction while facing the front of the user. .. Further, since the clip portion 22 further includes the second tongue piece portion 22b extending above the light projector 100, the light projector 100 can be more reliably fixed to the safety belt SB. The first tongue piece portion 22a and the second tongue piece portion 22b are not continuous and there is a gap between the first tongue piece portion 22a and the second tongue piece portion 22b. The projector 100 can be fixed to the safety belt SB without removing the SB from the body.

  The clip portion 22 including the first tongue piece portion 22a and the second tongue piece portion 22b as described above is obtained, for example, by forming the first cutout portion 21a into a substantially X shape. Of course, the shape of the first cutout portion 21a is not limited to this. In addition to the substantially X-shape illustrated, it may have a substantially H-shape, a substantially M-shape, a substantially W-shape, a substantially V-shape, a substantially U-shape and the like.

  Further, in the illustrated example, the center of gravity of the projector 100 is located in front of the center of the projector 100 in the front-rear direction, and the wide portion WR of the housing 20 is also located in front of the center of the projector 100 in the front-rear direction. Therefore, the wide portion WR abuts on the user's body (specifically, from the waist to the thighs) to prevent the projector 100 from going down and prevents the projector 100 from facing forward. It can be maintained reliably. In this manner, the locking means (clip portion 22) arranged in the narrow portion NR and the wide portion WR make it easy to maintain the state of illuminating the front by the projector 100 fixed to the user's body.

  The width and length of the first tongue piece portion 22a and the second tongue piece portion 22b of the clip portion 22 are not particularly limited, and are appropriately set so that the housing 20 can be locked to the safety belt SB with sufficient certainty. Can be done. The first tongue piece portion 22a and the second tongue piece portion 22b preferably have different lengths. The first tongue piece 22a and the second tongue piece 22b have different lengths, that is, by using a relatively long tongue piece and a relatively short tongue piece in combination, the tongue is attached to the safety belt SB. There is an advantage that it is easy to hang one piece and that the safety belt SB does not easily come off from the clip portion 22. As shown in FIG. 3 and the like, the first tongue piece portion 22a may be longer than the second tongue piece portion 22b, or conversely, the second tongue piece portion 22b may be longer than the first tongue piece portion 22a. When the housing 20 is locked to the safety belt SB by the clip portion 22, first, the longer tongue piece is hung on the safety belt SB, and then the short tongue piece is hung on the safety belt SB. Become. When the lengths of the first tongue piece 22a and the second tongue piece 22b are the same, if both the first tongue piece 22a and the second tongue piece 22b are long, it is difficult to hang the tongue piece on the safety belt SB. (In other words, it is difficult to attach the light projector 100). If both the first tongue piece portion 22a and the second tongue piece portion 22b are short, the safety band SB may easily come off from the clip portion 22.

  Further, in the illustrated example, the clip portion 22 includes one first tongue piece portion 22a and one second tongue piece portion 22b, but the clip portion 22 includes the first tongue piece portion 22a and/or the second tongue piece portion 22a. A plurality of tongue pieces 22b may be included. For example, the clip portion 22 may include two first tongue pieces 22a and one second tongue piece 22b. Further, the clip portion 22 does not have to include the second tongue piece portion 22b. When the first cutout portion 21a is substantially H-shaped, the clip portion 22 includes one first tongue piece portion 22a and one second tongue piece portion 22b, as in the case of the substantially X-shaped portion. On the other hand, when the first cutout portion 21a is substantially M-shaped, the clip portion 22 includes one first tongue piece portion 22a and two second tongue piece portions 22b. Further, when the first cutout portion 21a is substantially W-shaped, the clip portion 22 includes two first tongue piece portions 22a and one second tongue piece portion 22b. When the first cutout portion 22a is substantially V-shaped or substantially U-shaped, the clip portion 22 includes one first tongue piece portion 22a and does not include the second tongue piece portion 22b.

  Although the clip portion 22 formed integrally with the housing 20 is illustrated as the locking means here, the locking means is not limited to this. The locking means may be formed integrally with the housing 20, or may be formed separately from the housing 20. The locking means formed separately from the housing 20 may be joined to the housing 20 or may be an attachment member attachable to and removable from the housing 20. FIG. 22 shows an example of such an attachment member. 22(a), (b), (c) and (d) are a top view, a side view, a front view and a rear view schematically showing the attachment member 70 functioning as a locking means, respectively.

  As shown in FIGS. 22A, 22</b>B, 22</b>C and 22</b>D, the attachment member 70 has a bottom portion 71 and a side wall portion 72 extending upward from one end of the bottom portion 71. The cross-sectional shape of the attachment member 70 is substantially L-shaped.

  As shown in FIG. 22A, the bottom portion 71 has a through hole 71a near the center.

  As shown in FIG. 22( c ), a substantially X-shaped (also referred to as a substantially H-shaped) cutout portion 72 a is formed on the front surface side of the side wall portion 72. Further, as shown in FIGS. 22B and 22D, a plurality of (here, two) protrusions 72b are provided on the rear surface side of the side wall portion 72. The tip of the protrusion 72b has a flange shape.

  Further, the attachment member 70 includes a clip portion 73 having a shape defined by the cutout portion 72a of the side wall portion 72, as shown in FIG. The clip portion 73 includes a first tongue piece portion 73a extending downward and a second tongue piece portion 73b extending upward.

  The attachment member 70 having the above-described configuration can be attached to the housing 20 by inserting the tripod mounting boss 26 into the through hole 71a of the bottom portion 71 and hooking the projection 72b of the side wall portion 72 on the heat dissipation hole of the housing 20. it can. Further, the attachment member 70 can be locked (that is, can be attached) to the safety belt SB by the clip portion 73. At the time of actual use, the attachment member 70 is attached to the safety belt SB in advance, and the attachment member 70 is attached to the projector 100 if necessary, so that the projector 100 can be fixed to the user's body.

  When the attachment member 70 separate from the housing 20 is used, it is not necessary to form a large-sized heat dissipation hole like the first cutout portion 21a in the housing 20. Therefore, since the size of the heat dissipation hole can be reduced, it is possible to reduce the possibility of catching the light projector 100 on something when the light projector 100 is dragged.

(Preferable layout of switches and signal lights)
A preferred arrangement of the first switch (signal switch) 40, the second switch (light distribution changeover switch) 50, and the signal indicator lamp 60 will be described by taking the floodlight 100 of the first embodiment as an example.

  In the floodlight 100 shown in FIG. 1 and the like, the first switch 40 and the second switch 50 are arranged within a range where the fingers of the hand holding the handle 30 can reach. In the illustrated example, the first switch 40 and the second switch 50 are located in front of the handle 30 in the longitudinal direction of the housing 20. The first switch 40 and the second switch 50 are arranged on the upper portion of the housing 20 (more specifically, the box portion 20a), and the switch mechanism portion of the first switch 40 and the second switch 50 (here, (Not shown) is housed in the box portion 20a.

  Further, the signal indicator lamp 60 is arranged around the first switch 40 and the second switch 50. In the illustrated example, the signal indicator lamp 60 is located in front of the handle 30 in the longitudinal direction of the housing 20. The signal indicator lamp 60 is arranged on the upper part of the housing 20 (more specifically, the box portion 20a). When viewed from above, the signal indicator lamp 60, the first switch 40, and the second switch 50 are arranged so as to be located at the vertices of a virtual triangle. In the illustrated example, the second switch 50 is located in front of the first switch 40 and the signal indicator lamp 60 in the longitudinal direction of the housing 20.

  As described above, the first switch (signal switch) 40 and the second switch (light distribution changeover switch) 50 are arranged within the reach of the finger of the hand holding the handle 30 (hereinafter, referred to as “hand”). Then, each of the signal transmission and the light distribution switching can be performed by a one-handed operation with a holding hand. Therefore, it is not necessary to open the hand that does not grip the handle 30 or place the projector 100 on the ground. Therefore, the operability of the projector 100 can be improved.

  Here, the “range of the fingers of the holding hand” can be set based on the average hand size (finger length) of an adult. In the configuration illustrated in the present embodiment, the first switch 40 and the second switch 50 are located in front of the handle 30. In this case, the “range within which the fingers of the handle reach” is, for example, a range within 50 mm from the front end 30fe (see FIG. 3) of the handle 30.

  Considering the posture of the hand when gripping the handle 30, it is preferable to operate the first switch 40 and the second switch 50 with the thumb. As illustrated, when the first switch 40 and the second switch 50 are located in front of the handle 30 in the longitudinal direction of the housing 20, the operation with the thumb is easy.

  From the viewpoint of ease of operation with the thumb, it is preferable that the first switch 40 and the second switch 50 are not largely separated from the axis line 30x (see FIG. 4) of the handle 30, in other words, the handle 30 is substantially the same. It is preferably located on the axis line 30x.

  Further, in the illustrated example, the signal indicator lamp 60 is arranged around the first switch 40 and the second switch 50. This facilitates visual recognition of the signal indicator lamp 60. On the other hand, for example, if the indicator lamp is arranged on the side surface of the floodlight main body, the user may not be able to visually recognize the indicator lamp (that is, the indicator lamp may enter the blind spot of the user).

  From the viewpoint of easy visibility, it is preferable that the signal indicator lamp 60 is located in front of the handle 30 in the longitudinal direction of the housing 20. When the signal indicator lamp 60 is located in front of the handle 30, the signal indicator lamp 60 is not hidden by the hand holding the handle 30.

  Note that the arrangement of the first switch 40, the second switch 50, and the signal indicator lamp 60 is not limited to the illustrated example. For example, the positions of the first switch 40 and the second switch 50 may be interchanged, or the positions of the signal indicator lamp 60 and the first switch 40 or the second switch 50 may be interchanged. From the viewpoint of ease of visual recognition, in the longitudinal direction of the housing 20, the signal indicator lamp 60 is located in front of the first switch 40 and the second switch 50 (at the position of the second switch 50 shown in the figure). It can be said that the configuration in which the signal indicator lamp 60 is arranged is preferable.

(Waterproof section)
Needless to say, since the fire fighting activity involves water discharge work, the floodlight 100 is frequently exposed to water. Therefore, the floodlight 100 preferably has high waterproofness. Since the first switch 40 and the second switch 50 and the control board that controls the current supplied to the light source unit 10 can be arranged at distant positions, it is preferable that the floodlight 100 has at least two waterproof compartments. ..

  FIG. 23 shows an example of the waterproof section of the floodlight 100. In the example shown in FIG. 23, the floodlight 100 has three waterproof compartments WC1, WC2 and WC3.

  The first waterproof partition WC1 of the waterproof partitions WC1, WC2, and WC3 is a region corresponding to the box portion 20a of the housing 20, and the first switch 40, the second switch 50, and the signal indicator lamp 60 are arranged. .. The second waterproof section WC2 is an area corresponding to the rear part of the housing 20, and the buzzer 28 and a control board (not shown) are arranged therein. The third waterproof section WC3 is an area corresponding to the front part of the housing 20, and the light source section 10 is arranged therein. Since a known method can be used as a specific method for realizing the waterproof section, description thereof will be omitted here.

  As in the example shown in FIG. 23, by disposing both the first switch 40 and the second switch 50 in one waterproof compartment (here, the first waterproof compartment WC1), the number of waterproof compartments in the entire floodlight 100 is increased. Can be relatively small.

  As described above, the fire fighting floodlight 100 (100A, 100B) according to the embodiment of the present invention includes the light source unit 10, the housing 20 that houses the light source unit 10, and the user's hand that is arranged on the upper portion of the housing 20. In a plan view, the handle 30 has a handle 30 that is gripped, and the longitudinal direction of the handle 30 is in the front-back direction of the fire projector 100, and the handle 30 has at least one through hole. 31 is formed, and at least one through hole 31 is located between the center of gravity of the fire fighting light projector 100 and the rear end of the handle 30 in the front-back direction of the fire fighting light projector 100.

  In the floodlight 100 for fire fighting according to the embodiment of the present invention, since at least one through hole 31 is formed in the handle 30, the carabiner 300 can be carried by passing the carabiner 300 through the through hole 31. According to the embodiment of the present invention, since it is not necessary to separately attach a member for passing the carabiner 300 to the housing 20, the number of parts can be reduced, and the projector 100 can be reduced in weight. Furthermore, since the handle 30 itself is made lighter by forming the through hole 31 in the handle 30, it is also possible to obtain the effect of making the projector 100 as a whole lighter. Further, when the carabiner 300 is passed through the through hole 31 formed in the handle 30, it is possible to prevent the carabiner 300 from slipping (shifting) as in the case where the carabiner 300 is passed between the handle 30 and the housing 20. It is possible to stabilize the posture of the projector 100 when carrying the carabiner 300. Further, in the fire fighting light projector 100 according to the embodiment of the present invention, the through hole 31 of the handle 30 is located between the center of gravity of the light projector 100 and the rear end of the handle 30 in the front-back direction of the light projector 100. That is, the through hole 31 of the handle 30 is located behind the center of gravity of the projector 100. As a result, it is possible to prevent the light source unit 10 from facing obliquely upward when carrying the carabiner 300. If the light source unit 10 is directed obliquely upward, there is a risk that the face of a person will be irradiated with light. As described above, according to the embodiment of the present invention, it is possible to obtain the floodlight 100 for fire fighting, which has a structure suitable for carrying using the carabiner 300 and can realize weight reduction.
