However, in the case of the technique of Non-Patent Document 1, it is convenient to use the carabiner attachment part of the bracket when carrying, but when projecting light, the portable light projector must be held by the arm or the like. In addition, if a carabiner is attached to the handle when projecting light, the carabiner slips, making it difficult to fix the light path. In the case of the technique of Patent Document 1, there is a problem that the carabiner must be removed from the through-hole and replaced with another through-hole in order to change the optical path during projection.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a portable light projector in which the light path can be easily adjusted during light projection.

A portable light projector of the present invention includes a main body, a front support member, a rear support member, and a handle. The main body has a light source part on the front surface and a cable connection part on the rear surface. A front support member is attached to the front upper portion of the body. A rear support member is attached to the rear upper portion of the body. A handle is mounted between the front support member and the rear support member. The front support member forms a carabiner attachment on the front top of the handle. The handle has a plurality of recesses on the body side. One of the plurality of recesses is the position where the light source unit projects light in the horizontal direction when the center of gravity of the portable light projector is arranged directly below.

According to the portable light projector of the present invention, the carabiner attachment formed by the front support member is located above the handle. Therefore, even when using the carabiner attachment portion, compared to the portable light projector of Non-Patent Document 1, the amount of changing the direction of the portable light projector when making the light path constant using an arm or the like is small. Therefore, the orientation of the portable light projector can be stabilized with a small force. In addition, if you can work in a relatively stable state, such as when adjusting the optical path in a stationary state, you can adjust the optical path without attaching or detaching the carabiner by selecting the concave portion of the handle and placing the carabiner. can.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail. Components having the same function are given the same number, and redundant description is omitted.

FIG. 1 is a perspective view of the portable light projector of Embodiment 1 as viewed obliquely from the front, FIG. 2 is a perspective view of the portable light projector of Embodiment 1 as viewed obliquely from the rear, and FIG. is viewed from the side. A portable light projector 100 of Example 1 includes a main body 10 , a front support member 20 , a rear support member 30 and a handle 40 . Note that the front support member 20 and the rear support member 30 are also called brackets.

The main body 10 has a light source section 11 on its front surface and a connection section 12 for connecting a cable 90 on its rear surface. In addition, an alarm switch 13, an alarm display lamp 14, a selector switch 15, and the like are also arranged on the main body 10. As shown in FIG. The light source unit 11 includes a plurality of light sources such as LEDs (Light Emitting Diodes). The connection portion 12 is connected to a cable 90 for external power supply and communication. The alarm switch 13 is desirably placed within reach of the user's thumb when holding the handle 40 so that the user can immediately press it in case of emergency. The alarm indicator lamp 14 is arranged at a position where it is unlikely that it will be obstructed by the user's arm, hand, or the like. Specifically, as shown in FIGS. 1 to 3, it may be arranged in the front upper portion of the main body 10. FIG. The change-over switch 15 is a switch for adjusting the degree of condensing/diffusion of the light projected from the light source section 11 . Since the changeover switch 15 does not need to be switched frequently, it is desirable to arrange it in a position where it is not mistaken for the alarm switch 13 in a hurry.

The front support member 20 is attached to the front upper portion of the main body 10 . FIG. 4 is a diagram showing an example of a front support member. The front support member 20 may be made of metal such as stainless steel. The front support member 20 has a body attachment hole 22 for attaching the front support member 20 to the main body 10 and a handle attachment hole 23 for attaching the handle 40 to the front support member 20 . The front support member 20 also has operating holes 25 for locating the alarm switch 13 and the alarm indicator lamp 14 in the positions described above. Further, the front support member 20 forms a carabiner attachment portion 21 on the front upper portion of the handle 40 . As shown in FIG. 3 , the tip of the carabiner attachment portion 21 may be inserted into a slit 48 formed in the upper front portion of the handle 40 . By inserting the tip of the carabiner attachment portion 21 into the slit 48, deformation of the carabiner attachment portion 21 during use can be prevented. However, the slit 48 may be omitted (the slit 48 is not shown in FIGS. 1, 2, etc.). Since a carabiner used for firefighting is generally 10 mm or 12 mm in diameter, the carabiner attachment portion 21 should be of a size that allows the carabiner to easily pass through, for example, a diameter of about 12.5 to 15 mm.

The alarm switch 13 and the alarm indicator lamp 14 may be positioned higher than the upper surface of the handle 40 and hidden by the carabiner mounting portion 21 or the front support member 20 . By arranging in such a position, it is possible to easily prevent the alarm switch 13 and the alarm indicator lamp 14 from being damaged by the carabiner attached to any place of the portable light projector 100 .

The rear support member 30 is attached to the rear upper portion of the main body 10 . FIG. 5 is a diagram showing an example of a rear support member. The rear support member 30 may be made of metal such as stainless steel. The rear support member 30 has a body attachment hole 32 for attaching the rear support member 30 to the main body 10, a handle attachment hole 33 for attaching the handle 40 to the rear support member 30, and a connection hole 35 for the connection portion 12. . Also, the rear support member 30 forms a carabiner attachment portion 31 on the rear upper portion of the handle 40 . As shown in FIG. 3 , the tip of the carabiner attachment portion 31 may be inserted into a slit 49 formed in the rear upper portion of the handle 40 . By inserting the tip of the carabiner attachment portion 31 into the slit 49, deformation of the carabiner attachment portion 31 during use can be prevented. However, the slit 49 may be omitted (the slit 49 is not shown in FIGS. 1 and 2). The carabiner attachment portion 31 may also have a size that allows easy attachment of a carabiner with a diameter of 10 mm.

A handle 40 is attached between the front support member 20 and the rear support member 30 . FIG. 6 is a diagram showing an example of a handle. The handle 40 is formed with a plurality of recesses 41, 42, 43 on the main body 10 side. Since carabiners used for firefighting are generally 10 mm or 12 mm in diameter, the depth of recesses 41, 42, 43 should be 5 mm or more. The recesses 41, 42, 43 can be smaller than the through holes formed in the handle shown in US Pat. Therefore, since the number can be increased, it is easy to perform finer adjustment of the projection direction. In addition, since the strength of the handle is less likely to be affected, there is an advantage that the design is easy. The deeper the recesses 41 , 42 , 43 are, the more difficult it is for the carabiner to move. If the number of recesses is to be reduced (for example two), the recesses may be shaped like slits. Also, an elastic material may be arranged on the surfaces of the recesses 41, 42, 43 to prevent slippage. The handle 40 also has bracket mounting holes 47 for mounting with the front support member 20 . Although not visible in FIG. 6, the handle 40 also has bracket mounting holes on the opposite side of the bracket mounting holes 47 for mounting with the rear support member 30 .

One of the plurality of recesses 41, 42, 43 is a position where the light source unit 11 projects light in the horizontal direction when the center of gravity of the portable light projector 100 is arranged directly below. Line AA in FIG. 3 indicates a vertical line passing through the center of gravity when the light source unit 11 projects light in the horizontal direction. In the case of FIG. 3, the concave portion 41 is "the position where the light source unit 11 projects light in the horizontal direction when the center of gravity of the portable light projector 100 is arranged directly below".

FIG. 7 is a diagram showing a case where the carabiner 80 is attached to the carabiner attachment portion 21 and the portable light projector 100 is hung, and FIG. FIG. 9 is a diagram showing a state in which the carabiner 80 is arranged in the concave portion 41 and the portable light projector 100 is suspended. In the case of FIG. 7, the light source section 11 faces slightly upward. In the case of FIG. 8, the light source unit 11 faces downward (to the feet). In the case of FIG. 9, the light source section 11 is directed substantially horizontally. In the case of firefighting, the user often attaches the carabiner 80 to the waist safety belt. By selecting the position of the carabiner 80 attached to the safety belt, the user can project light in a desired direction.

According to the portable light projector 100 , the carabiner attachment portion 21 formed by the front support member 20 and the carabiner attachment portion 31 formed by the rear support member 30 are positioned above the handle 40 . Therefore, even when the carabiner attachment parts 21 and 31 are used, compared to the portable light projector of Non-Patent Document 1, the amount of changing the direction of the portable light projector 100 when making the optical path constant using an arm or the like is small. . Therefore, the orientation of the portable light projector 100 can be stabilized with a small force. In addition, when it is possible to work in a relatively stable state, such as when adjusting the optical path in a stationary state, the carabiner 80 can be attached by selecting the concave portions 41, 42, and 43 of the handle 40 and placing the carabiner 80 thereon. The optical path can be adjusted without attaching or detaching.
[Modification 1]

FIG. 10 shows a side view of the portable light projector of the first embodiment in which the carabiner movement prevention tool is also arranged. Handle 40 also has a carabiner detent 50 . The carabiner movement prevention tool 50 shown in FIG. 10 is a ring-shaped elastic body whose natural length is shorter than the peripheral length of the portion of the handle 40 other than the concave portion. Therefore, since the carabiner movement prevention tool 50 holds the handle 40 at least in a portion other than the concave portion, it is difficult to move. However, it is possible for the user to move the carabiner movement prevention device 50 in the longitudinal direction of the handle.

For example, when the carabiner 80 is arranged in the recess 41 as shown in FIG. 10, if the carabiner movement prevention tool 50 is moved to the position shown in FIG. It becomes difficult to move. FIG. 11 is a view showing the carabiner movement prevention tool when it is desired to move the carabiner. Since the carabiner movement prevention tool 50 can be moved, it can be moved to the position shown in FIG. 11 when not needed.

In addition, in this modified example, a ring-shaped elastic body is shown as the carabiner movement prevention tool 50 . However, the carabiner movement prevention tool 50 may be fixed to the handle 40 by pinching the handle like a clip, and may be structured to prevent movement of the carabiner 80 . Alternatively, the carabiner movement prevention tool 50 may be shaped like a bifurcated clothespin, and may have a structure in which the handle is held while the carabiner 80 is sandwiched between the bifurcated parts. The carabiner movement prevention tool 50 has a structure that can hold the position to which the user intentionally moves, and may have a structure that prevents the movement of the carabiner 80 .
[Modification 2]

FIG. 12 shows a side view of the portable light projector of Modification 2. As shown in FIG. The portable light projector 101 of Modification 2 differs from the portable light projector 100 only in that the rear support member 38 does not form the carabiner attachment portion 31 . For example, if a carabiner 80 is arranged at the connecting portion between the handle 40 and the rear support member 38 indicated by "B" in FIG. Therefore, even without the carabiner attachment part 31, the foot can be illuminated. Further, the effects obtained by the carabiner attachment portion 21 and the concave portions 41, 42, 43 of the handle 40 are the same as those of the portable light projector 100 of the first embodiment. Also, the portable light projector 101 may be provided with the carabiner movement prevention tool 50 described in the first modification. The effect obtained by the carabiner movement prevention tool 50 is the same as that of the first modification.

According to the portable light projector 101 , the carabiner attachment portion 21 formed by the front support member 20 is positioned above the handle 40 . Therefore, even when the carabiner attachment portion 21 is used, compared to the portable light projector of Non-Patent Document 1, the amount of changing the orientation of the portable light projector 100 when using an arm or the like to keep the optical path constant is small. Therefore, the orientation of the portable light projector 100 can be stabilized with a small force. In addition, when it is possible to work in a relatively stable state, such as when adjusting the optical path in a stationary state, the carabiner 80 can be attached by selecting the concave portions 41, 42, and 43 of the handle 40 and placing the carabiner 80 thereon. The optical path can be adjusted without attaching or detaching.
