  In one embodiment, the housing has a wide portion that is wider in the left-right direction than the other portions of the housing, and the wide portion is located in front of the center in the front-rear direction of the fire projector. ing.

  In one embodiment, the fire projector is powered by an external power source.

  In one embodiment, the fire-fighting floodlight is connected to a signal device via a connection cable.

  In one embodiment, the floodlight projector has a handle that is disposed on an upper portion of the housing and is gripped by a user's hand, and a first switch that receives an operation of transmitting a signal to the signal device via the connection cable. And a second switch for accepting an operation for switching the light distribution of the light source unit, wherein the first switch and the second switch are disposed within a range where a finger of a hand holding the handle can reach.

  In one embodiment, the first switch and the second switch are located in front of the handle in the longitudinal direction of the housing.

  In one embodiment, the first switch and the second switch are located substantially on the axis of the handle.

  In one embodiment, the fire-fighting floodlight further includes a signal indicator light that is turned on in response to transmission of a signal to the signal device, and the signal indicator light is disposed around the first switch and the second switch. Has been.

  In one embodiment, the fire projector has at least two waterproof compartments.

  In one embodiment, both the first switch and the second switch are arranged in one of the at least two waterproof sections.

  Another fire projector according to an embodiment of the present invention is a fire projector provided with a light source unit and a housing that houses the light source unit, and is provided on at least one of both side surfaces of the housing. The locking means further includes locking means for locking the casing to a safety belt wound around a user's waist, the casing including a wide portion having a relatively wide width in the left-right direction; A narrow portion having a relatively narrow width in the direction, and the locking means is disposed in the narrow portion of the housing.

  Still another fire projector according to an embodiment of the present invention is a fire projector having a light source unit and a housing that houses the light source unit, and is provided on at least one of both side surfaces of the housing. The clip portion further includes a first tongue piece portion extending downward and a second tongue piece portion extending upward.

  In one embodiment, the first tongue piece portion and the second tongue piece portion have different lengths from each other.

  The floodlight projector according to the embodiment of the present invention includes a locking means for locking the housing to a safety belt wound around the user's waist, and this locking means is more than the center in the front-rear direction of the firelight projector. Located at the center of gravity of the floodlight for fire fighting. Since the locking means is located closer to the center of gravity than the center in the front-rear direction, locking is performed at a position relatively close to the center of gravity, so the fire projector is kept in a state where the light source part faces the front of the user. It becomes easy to fix to the user's body. On the other hand, if the locking means is located on the opposite side of the center of gravity with respect to the center in the front-rear direction, the distance from the center of gravity of the fire projector to the locking means may be relatively long, and the light source unit There is a possibility that it becomes difficult to fix the floodlight projector to the user's body while facing the front of the user.

  By including a curved surface portion in which the side surface on which the locking means of the housing is provided is recessed inward in the left-right direction, when the housing is locked to the safety belt (that is, the fire projector is fixed), the housing is It becomes easy to fit the body. That is, not only the locking means but also the curved surface portion comes into contact with the user's body. Therefore, the stability when the floodlight projector is fixed is increased. Even if the user moves quickly, the load can be prevented from concentrating only on the locking means, so that the locking means is not easily damaged. In addition, since the fire-fighting projector is supported in a relatively large area, it becomes easier to fix the light source unit facing the front of the user.

  When the locking means is provided on each of the both side surfaces of the housing, the fire projector can be fixed to both the right side and the left side of the user's waist. Therefore, there is an advantage that the fire-fighting floodlight can be suitably used regardless of the user's dominant hand.

  When the locking means is a clip portion having a shape defined by a cutout portion on the side surface of the housing, the number of parts is reduced, the weight of the housing is reduced, and the design of the floodlight projector is enhanced. Can do.

  The cutout formed in the side surface of the housing may function as a heat dissipation hole for releasing heat generated in the light source unit. By using the heat radiating hole as a notch that defines the shape of the clip portion, there is no need to form an extra hole in the housing.

  When the clip portion includes the first tongue piece portion extending downward, it becomes easy to lock the fire-fighting floodlight while facing the front of the user with respect to the safety belt extending in the horizontal direction.

  When the clip portion further includes the second tongue piece portion extending upward, the fire projector can be more reliably fixed to the safety belt.

  It is preferable that the first tongue piece portion and the second tongue piece portion have different lengths. When the first tongue piece and the second tongue piece are different in length, that is, by using a combination of a relatively long tongue piece and a relatively short tongue piece, the tongue piece is attached to the safety belt SB. The advantage is that the safety band SB is not easily detached from the clip portion 22.

  The clip part including the first tongue piece part and the second tongue piece part as described above is obtained, for example, by making the notch part into a substantially X shape.

  The center of gravity of the fire projector is typically located in front of the center of the fire projector in the front-rear direction.

  The housing may have a wide portion that is wider in the left-right direction than other portions of the housing. If the center of gravity of the firelight projector is located in front of the center in the front-rear direction of the firelight projector, if the wide part of the housing is also in front of the center in the front-rear direction of the firelight projector, the wide part is It is possible to prevent the fire projector from falling forward by contacting the body (specifically, from the waist to the thigh). Therefore, it is possible to more reliably maintain the state in which the fire projector is directed forward of the user.

  Embodiment of this invention is used suitably for the floodlight projector for which electric power is supplied from an external power supply. By supplying power from an external power source, the fire projector can be used for a long time (a desired time required for fire fighting activities).

  The floodlight projector according to the embodiment of the present invention may be connected to a signal device via a connection cable.

  Moreover, the floodlight projector by embodiment of this invention is further provided with the 1st switch which receives operation which transmits a signal to a signal device via a connection cable, and the 2nd switch which receives operation which switches the light distribution of a light source part. May be. In that case, it is preferable that the first switch and the second switch are arranged within a range where a finger of a hand holding the handle can reach. Thereby, each of transmission of a signal and switching of light distribution can be performed by one-hand operation with the hand holding the handle. Therefore, there is no need to open the hand that does not hold the handle or to place a fire projector on the ground. Therefore, the operativity of the floodlight projector can be improved.

  Considering the posture of the hand when gripping the handle, it is preferable to operate the first switch and the second switch with the thumb. When the first switch and the second switch are located in front of the handle in the longitudinal direction of the housing, the operation with the thumb can be easily performed.

  From the viewpoint of ease of operation with the thumb, it is preferable that the first switch and the second switch are not greatly separated from the axis of the handle, in other words, substantially located on the axis of the handle. preferable.

  The floodlight projector according to the embodiment of the present invention may further include a signal indicator lamp that is turned on in response to transmission of a signal to the signal device. When the signal indicator lamp is disposed around the first switch and the second switch, the signal indicator lamp is easily visible.

  From the viewpoint of ease of visual recognition, the signal indicator lamp is preferably located in front of the handle in the longitudinal direction of the housing. When the signal indicator lamp is positioned in front of the handle, the signal indicator lamp is not hidden by the hand holding the handle.

  Further, from the viewpoint of easy visual recognition, it is preferable that the signal indicator lamp is positioned in front of the first switch and the second switch in the longitudinal direction of the housing.

  Since the first switch, the second switch, and the control board that controls the current supplied to the light source unit can be arranged at separate positions, it is preferable that the fire projector has at least two waterproof sections.

  When both the first switch and the second switch are arranged in one waterproof section, the number of waterproof sections in the entire fire-fighting floodlight can be relatively reduced.

  In another fire projector according to an embodiment of the present invention, the housing has a wide portion having a relatively wide width in the left-right direction and a narrow portion having a relatively narrow width in the left-right direction, Locking means for locking the casing to the belt is disposed in the narrow portion of the casing. The locking means arranged in the narrow part of the casing locks the casing to the safety belt, and the wide section of the casing is in contact with the user's body (specifically, from the waist to the thigh). By preventing the fire projector from being lowered forward, it becomes easy to fix the fire projector to the user's body with the light source portion facing the front of the user.

  Still another fire projector according to the embodiment of the present invention includes a clip portion provided on at least one of both side surfaces of the housing. Since this clip part contains the 1st tongue piece part extended below, it becomes easy to lock the floodlight for fire fighting toward the user's front with respect to the safety belt extended in a horizontal direction. Moreover, since this clip part contains the 2nd tongue piece part extended upwards, the floodlight projector for fire fighting can be more reliably fixed with respect to a safety belt. Therefore, it becomes easy to fix the floodlight projector to the user's body with the light source part facing the front of the user.

  It is preferable that the first tongue piece portion and the second tongue piece portion have different lengths. When the first tongue piece and the second tongue piece are different in length, that is, by using a combination of a relatively long tongue piece and a relatively short tongue piece, the tongue piece is attached to the safety belt SB. The advantage is that the safety band SB is not easily detached from the clip portion 22.

That is, the buzzer 28 emits a buzzer sound in response to signal transmission (typically in synchronization).

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

  A specific configuration of the light source unit 10 will be described with reference to FIGS. 6 to 9. 6, FIG. 7, FIG. 8, and FIG. 9 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. 6 to 9, the light source unit 10 includes 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. 7, the plurality of LED elements 11 includes a plurality (six in this case) of first LED elements 11 a positioned relatively outside when viewed from the front direction, and a plurality of LEDs positioned relatively inside. (Here, six) second LED elements 11b. Note that the number and arrangement of the first LED elements 11a and the second LED elements 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 1st lens part 12 and the 2nd lens part 13 are each formed from the resin material or the glass material.

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

  The light emitted from each LED element 11 is given a desired directivity by the corresponding lens (the first lens 12a or the second lens 13a). In the illustrated light source unit 10, the focal length of the first lens 12a is different from the focal length of the second lens 13a. By operating the second switch 50, it is possible to switch between a state in which only the first LED element 11a is lit and a 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 where only the first LED element 11a is lit is the condensed irradiation state and the state where only the second LED element 11b is lit 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 may be different from each other. If the light emission color of the first LED element 11a is different from the light emission color of the second LED element 11b, the light emission color of the light source unit 10 can also be switched when switching the light distribution. For example, one of the first LED element 11a and the second LED element 11b is white and the other is yellow, for example, as a configuration in which the emission color of the first LED element 11a is different from the emission color of the second LED element 11b. A configuration can be employed. In a space filled with smoke, the visibility varies depending on the emission color (for example, yellow light is more visible than white light). Further improvement can be achieved.

  An example of the signal device will be described with reference to FIG. FIG. 10 is a side view schematically showing the signal device 200.

  FIG. 11 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. 11, 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. 11, 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 side). Further, the clip portion 22 which is a locking means is also located in front of the center of the projector 100 in the front-rear direction. That is, the clip part 22 is located on the center of gravity side of the projector 100 with respect to the center of the projector 100 in the front-rear direction. In FIG. 11, the position of the center of the clip portion 22 in the front-rear direction is indicated by a chain line 22cp. As can be seen from FIG. 11, “the locking means (clip portion 22) is located closer to the center of gravity of the projector 100 than the center in the front-rear direction of the projector 100” means that the locking means (clip portion 22). This means that the center in the front-rear direction (position indicated by the chain line 22 cp) is located closer to the center of gravity than the center in the front-rear direction of the projector 100.

  FIG. 12 shows a state in which the housing 20 is locked to the safety belt SB by the clip portion 22. The width and thickness of the safety belt SB are, for example, 50 mm and 2 mm, respectively. As shown in FIG. 12, the safety belt SB is hooked on the first tongue piece 22a and the second tongue piece 22b of the clip portion 22 (in other words, the back side of the first tongue piece 22a and the second tongue piece 22b). The housing 20 can be locked to the safety belt SB by passing it through the first notch 21a (so that a part of the safety belt SB is positioned at the same position). As a result, the projector 100 can be fixed to the user's waist while facing forward. At this time, the clip portion 22 locks the housing 20 to the safety belt SB at least at three points. In the illustrated example, the clip portion 22 is locked at three points. More specifically, the first tongue piece 22a is locked at two points and the second tongue piece 22b is locked at one point.

  As described above, the projector 100 according to the present embodiment includes the locking means (the clip portion 22) for locking the housing 20 to the safety belt SB, and the locking means is more than the center in the front-rear direction of the projector 100. It is located on the center of gravity side of the projector 100. Since the locking means is positioned closer to the center of gravity than the center in the front-rear direction, locking is performed at a position relatively close to the center of gravity, so that the projector 100 can be placed with the light source unit 10 facing the front of the user. It becomes easy to fix to the user's body. On the other hand, if the locking means is located on the opposite side of 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 It may be difficult to fix the projector 100 to the user's body while facing the front of the user.

  Thus, the projector 100 of this embodiment 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 (grip portion 22) is provided on each of the both side surfaces of the housing 20, but the locking means is provided only on one of the both side surfaces of the housing 20 (left side surface and right side surface). Any one of them). If the locking means is provided on each of the both side surfaces of the housing 20 as in this embodiment, the projector 100 can be fixed to either the right side or the left side of the user's waist. The advantage that the projector 100 can be suitably used regardless of the above is obtained.

  As already described, in the present embodiment, each of both side surfaces of the housing 20 includes a curved 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 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. 13 and 14. FIG. 13 is a side view of the projector 100, and the guide portion GP is hatched for easy understanding. FIG. 14 is a top view of the projector 100 and schematically shows the user's waist WA.

  In the present embodiment, the guide portion GP is positioned at the center in the vertical direction of the side surface of the housing 20 as shown in FIG. 13, and as shown in FIG. 14, the user's waist WA (more specifically, Is in contact with the safety belt SB) wound around the waist WA.

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

  The specific shape of the guide part GP is set so as to follow the user's waist as much as possible. The curvature radius of the guide part GP is, for example, not less than 250 mm and not more than 1300 mm.

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

  When the clip portion 22 includes the first tongue piece portion 22a extending below the projector 100, the projector 100 can be easily locked to 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 projector 100, the projector 100 can be more reliably fixed to the safety belt SB. The first tongue piece 22a and the second tongue piece 22b are not continuous, and there is a gap between the first tongue piece 22a and the second tongue piece 22b. The projector 100 can be fixed to the safety belt SB without removing the SB from the body.

  The clip part 22 including the first tongue piece part 22a and the second tongue piece part 22b as described above can be obtained, for example, by making the first notch part 21a substantially X-shaped. Of course, the shape of the 1st notch part 21a is not limited to this. In addition to the substantially X shape illustrated, it may be a substantially H shape, a substantially M shape, a substantially W shape, a substantially V shape, a substantially U shape, or the like.

  In the present embodiment, the center of gravity of the projector 100 is positioned 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 positioned in front of the center of the projector 100 in the front-rear direction. Therefore, when the wide part WR abuts on the user's body (specifically, from the waist to the thigh), the projector 100 is prevented from being forwardly lowered, and the projector 100 is more directed to the front of the user. It can be reliably maintained. Thus, it becomes easy to maintain the state which illuminates the front with the light projector 100 fixed to the user's body by the locking means (clip part 22) arrange | positioned at the narrow part NR, and the wide part WR.

  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 sufficiently locked with the safety belt SB. Can be done. The first tongue piece 22a and the second tongue piece 22b are preferably different in length from each other. When the first tongue piece 22a and the second tongue piece 22b have different lengths, that is, by using a combination of a relatively long tongue piece and a relatively short tongue piece, the tongue is attached to the safety belt SB. The advantage that it is easy to hang one piece and the safety band SB is not easily detached from the clip portion 22 is obtained. As shown in FIG. 3 etc., the 1st tongue piece part 22a may be longer than the 2nd tongue piece part 22b, and conversely, the 2nd tongue piece part 22b may be longer than the 1st tongue piece part 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 shorter tongue piece is hung on the safety belt SB. Become. When the first tongue piece 22a and the second tongue piece 22b have the same length and 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. (That is, it is difficult to attach the projector 100), and if both the first tongue piece 22a and the second tongue piece 22b are short, the safety band SB may be easily detached from the clip portion 22.

  In the illustrated example, the clip portion 22 includes the first tongue piece portion 22a and the second tongue piece portion 22b one by one, but the clip portion 22 includes the first tongue piece portion 22a and / or the second tongue piece portion 22b. A plurality of tongue pieces 22b may be included. For example, the clip part 22 may include two first tongue pieces 22a and one second tongue piece 22b. Furthermore, the clip part 22 does not need to include the second tongue piece part 22b. When the 1st notch part 21a is a substantially H shape, the clip part 22 contains the 1st tongue piece part 22a and the 2nd tongue piece part 22b one by one similarly to the case of a substantially X shape. 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. 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.

  In the present embodiment, the clip portion 22 formed integrally with the housing 20 is illustrated as the locking means, but 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 that can be attached to and detached from the housing 20. FIG. 15 shows an example of such an attachment member. FIGS. 15A, 15B, 15C, and 15D are a top view, a side view, a front view, and a rear view, respectively, schematically showing an attachment member 70 that functions as a locking means.

  As shown in FIGS. 15A, 15 </ b> B, 15 </ b> C, and 15 </ b> D, the attachment member 70 has a bottom portion 71 and a side wall portion 72 that extends 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. 15A, the bottom 71 has a through hole 71a near the center.

  As shown in FIG. 15 (c), a substantially X-shaped (substantially H-shaped) cutout 72 a is formed on the front side of the side wall 72. Further, as shown in FIGS. 15B and 15D, a plurality of (here, two) protrusions 72 b are provided on the back 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 notch 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 protrusion 72b of the side wall portion 72 on the heat radiation hole of the housing 20. it can. Further, the attachment member 70 can be locked (that is, attached) to the safety belt SB by the clip portion 73. In actual use, the projector 100 can be fixed to the user's body by attaching the attachment member 70 to the safety belt SB in advance and attaching the attachment member 70 to the projector 100 as necessary.

  When the attachment member 70 separate from the housing 20 is used, it is not necessary to form a large heat radiation hole in the housing 20 like the first cutout portion 21a. Therefore, since the size of the heat radiation hole can be reduced, for example, when the projector 100 is dragged, the possibility of hooking the projector 100 on something can be reduced.

  As already described, in the projector 100 according to the present embodiment, the first switch (signal switch) 40 and the second switch (light distribution change-over switch) 50 are referred to as a hand holding the handle 30 (hereinafter referred to as a “hand”). ) Is within the reach of your finger. Therefore, each of signal transmission and light distribution switching can be performed by a one-handed operation with a handle. Therefore, it is not necessary to open the hand that does not hold the handle 30 or to place the projector 100 on the ground. Thus, according to the present embodiment, the operability of the projector 100 can be improved.

  Here, the “range that the finger of the handle can reach” can be set based on the average hand size (finger length) of an adult. In the configuration exemplified in this embodiment, the first switch 40 and the second switch 50 are located in front of the handle 30. In this case, the “range that the finger of the handle can reach” is, for example, a range within 50 mm from the front end 30fe (see FIG. 3) of the handle 30 (in the illustrated example, within 80 mm from the front end of the handle member 31). Range).

  Although the example in which the handle 30 includes the handle member 31 and the convex portion 20b extending from the container main body 20 is shown here, the configuration of the handle 30 is not limited thereto. The handle 30 may be composed of three or more members, or may be a single member.

  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. If the first switch 40 and the second switch 50 are positioned in front of the handle 30 in the longitudinal direction of the housing 20 as in the present embodiment, 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 greatly separated from the axis 30a (see FIG. 4) of the handle 30, in other words, the handle 30 substantially. It is preferable to be located on the axis 30a.

  In the present embodiment, the signal indicator lamp 60 is disposed around the first switch 40 and the second switch 50. This facilitates visual recognition of the signal indicator lamp 60. On the other hand, in the projector of patent document 1, since the indicator lamp is arrange | positioned at the side surface of the projector main body, there exists a possibility that a user cannot visually recognize an indicator lamp (that is, an indicator lamp will enter into a user's blind spot).

  From the viewpoint of ease of visual recognition, the signal indicator lamp 60 is preferably positioned in front of the handle 30 in the longitudinal direction of the housing 20. When the signal indicator lamp 60 is positioned in front of the handle 30, the signal indicator lamp 60 is not hidden by the hand holding the handle 30.

  In addition, arrangement | positioning of the 1st switch 40, the 2nd 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 switched, and the positions of the signal indicator lamp 60 and the first switch 40 or the second switch 50 may be switched. From the viewpoint of ease of visual recognition, an arrangement in which the signal indicator lamp 60 is positioned in front of the first switch 40 and the second switch 50 in the longitudinal direction of the housing 20 (at the position of the second switch 50 shown in the figure). A configuration in which the signal indicator lamp 60 is disposed is preferable.

  Needless to say, since the fire fighting activities involve water discharge work, the floodlight 100 is frequently flooded. Therefore, it is preferable that the projector 100 has high waterproofness. Since the 1st switch 40 and the 2nd switch 50, and the control board which controls the electric current supplied to the light source part 10 can be arrange | positioned in the distant position, it is preferable that the light projector 100 has at least 2 waterproofing divisions. .

  In FIG. 16, the example of the waterproof division which the light projector 100 has is shown. In the example shown in FIG. 16, the projector 100 includes three waterproof sections WC1, WC2, and WC3.

  Of the waterproof sections WC1, WC2, and WC3, the first waterproof section WC1 is an area 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 disposed. . The second waterproof section WC2 is an area corresponding to the rear part of the housing 20, and a buzzer 28 and a control board (not shown) are arranged. The third waterproof section WC3 is an area corresponding to the front part of the housing 20, and the light source unit 10 is disposed therein. In addition, about the specific method for implement | achieving a waterproof division, since a well-known method can be used, the description is abbreviate | omitted here.

  As in the example shown in FIG. 16, by arranging both the first switch 40 and the second switch 50 in one waterproof section (here, the first waterproof section WC1), the number of waterproof sections in the projector 100 as a whole. Can be relatively reduced.

  As described above, the fire projector 100 according to the embodiment of the present invention is the fire projector 100 including the light source unit 10 and the housing 20 that houses the light source unit 10. Is provided with at least one of the locking means for locking the casing 20 to the safety belt SB wound around the user's waist, and the locking means is provided before and after the fire projector 100. It is located on the gravity center side of the floodlight projector 100 from the center in the direction.

  The floodlight projector 100 according to the embodiment of the present invention includes a locking unit that locks the housing 20 on the safety belt SB wound around the user's waist. It is located on the gravity center side of the floodlight projector 100 from the center in the direction. Since the locking means is positioned closer to the center of gravity than the center in the front-rear direction, locking is performed at a position relatively close to the center of gravity. It becomes easy to fix 100 to a user's body. On the other hand, when 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 fire projector 100 to the locking means may be relatively long. There is a possibility that it becomes difficult to fix the floodlight projector 100 to the user's body with the 10 facing the front of the user.

  In an embodiment, at least one side surface of the housing 20 includes a curved portion GP that is recessed inward in the left-right direction.

That is, not only the locking means but also the curved surface portion GP comes into contact with the user's body. Therefore, the stability when the floodlight projector 100 is fixed is increased. Even if the user moves quickly, the load can be prevented from concentrating only on the locking means, so that the locking means is not easily damaged. In addition, since the fire-fighting projector 100 is supported over a relatively large area, it becomes easier to fix the light source unit 10 while facing the front of the user.

  In an embodiment, the locking means is provided on each of both side surfaces of the housing 20.

  When the locking means is provided on each of the both side surfaces of the housing 20, the fire projector 100 can be fixed to either the right side or the left side of the user's waist. Therefore, the advantage which can use the floodlight projector 100 suitably regardless of a user's dominant hand is acquired.

  In an embodiment, at least one side surface of the housing 20 has a notch portion 21a, and the locking means is a clip portion 22 having a shape defined by the notch portion 21a.

When 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, the number of parts is reduced and the housing 20 is reduced in weight, and the design of the floodlight projector 100 for fire fighting is achieved. In one embodiment, the notch 21 a of the housing 20 functions as a heat radiating hole for releasing heat generated in the light source unit 10.

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

  In one embodiment, the first tongue piece 22a and the second tongue piece 22b have different lengths.

  The first tongue piece 22a and the second tongue piece 22b are preferably different in length from each other. When the first tongue piece 22a and the second tongue piece 22b have different lengths, that is, by using a combination of a relatively long tongue piece and a relatively short tongue piece, the tongue is attached to the safety belt SB. The advantage that it is easy to hang one piece and the safety band SB is not easily detached from the clip portion 22 is obtained.

  In a certain embodiment, the notch part 21a is a substantially X shape.

  The clip part 22 including the first tongue piece part 22a and the second tongue piece part 22b as described above can be obtained, for example, by making the notch part 21a substantially X-shaped.
