A helmet camera and a helmet according to an embodiment of the present invention will now be described.

FIG. 1 is a diagram showing a wearer wearing a helmet according to this embodiment.
A helmet camera 1 attached to a helmet 100 is connected to a main body 3 via a main body connection cable 2 such as a USB cable or HDMI (registered trademark) cable. The main body 3 is attached to a part other than the helmet 100, such as the chest or waist of the wearer of the helmet 100. As shown in FIG.
A wearer of the helmet 100 uses the helmet camera 1 to photograph the work situation or the situation of equipment at a construction site, factory facility, or the like.
The main body 3 includes transmission means for transmitting an image photographed by the helmet camera 1 to a place distant from the photographing place, and power supply means for supplying power to the helmet camera 1. - 特許庁By transmitting the situation of the site photographed by the wearer to a place away from the site, the work leader can easily grasp the situation of the site even if he/she is away from the site. Can give precise instructions to people. In addition, the main body 3 may be provided with storage means for storing the images taken by the helmet camera 1 .
As shown in FIG. 1, by separating the helmet camera 1 and the main body 3 and attaching only the helmet camera 1 to the helmet 100, the weight increase of the helmet 100 caused by attaching the photographing means can be reduced and the wearer can The burden can be reduced.

FIG. 2 is a perspective view showing a helmet to which a helmet camera is attached.
The helmet 100 is an industrial helmet (industrial protective cap) worn at construction sites, factories, and the like. The helmet 100 has a hemispherical cap body 101 and an eaves (brim) 102 projecting forward from the lower end of the front side of the cap body 101 .
The helmet camera 1 includes a camera section 10 having a photographing function and an attachment section 20 for attaching the camera section 10 to the canopy 102 of the helmet 100 .

3A and 3B are views showing a helmet to which a helmet camera is attached, FIG. 3A being a front view and FIG. 3B being a rear view.
As shown in FIG. 3, the camera unit 10 is positioned forward of the peripheral edge of the canopy 102, and the lower end 11a of the lens 11 is positioned below the canopy 102 when the lens 11 faces the front (horizontally). ing.
By attaching the camera unit 10 to the canopy 102 and positioning the lower end 11a of the lens 11 below the height of the tip of the canopy 102 in this way, the camera unit 10 is attached to the front surface of the cap body 101. position can be lowered. As a result, the position of the lens 11 is close to the eye level of the wearer, and the deviation between the shooting direction of the camera unit 10 and the line of sight can be reduced.

By lowering the height of the camera unit 10 and bringing the lens 11 closer to the wearer's eye level, the deviation between the photographing direction of the camera unit 10 and the wearer's line of sight can be reduced. On the other hand, if the height of the camera section 10 is lowered too much, the view of the wearer is blocked by the camera section 10 and narrowed. Therefore, it is preferable to position the lower end of the camera section 10 above the eye level of the wearer. In this embodiment, as shown in FIGS. 1 to 3, the height of the center of the lens 11 is substantially the same as the height of the central portion of the canopy 102 of the helmet 100, and the lower end of the camera section 10 is positioned at the wearer's eye level. Located above height. As a result, the wearer's field of vision can be sufficiently ensured.
The camera unit 10 is attached to the central portion of the canopy 102 of the helmet 100 so that the center of the lens 11 and the middle point of the wearer's eyes are positioned substantially on the same straight line. This makes it possible to further reduce the deviation between the imaging direction of the camera unit 10 and the line of sight of the wearer.

FIG. 4 is a diagram showing the configuration of the camera section.
The camera unit 10 includes a camera module 12 having a lens 11 , a rectangular control board 13 for controlling the camera module 12 , the camera module 12 and the control board 13 , and housed in a housing 14 .
One end of the main body connection cable 2 is connected to the control plate 13 . Power supply from the main body 3 to the control board 13 and communication between the main body 3 and the control board 13 are performed through the main body connection cable 2 .
The housing 14 has a two-part structure and includes a front housing 14A and a rear housing 14B. FIG. 4 shows a state in which the front housing 14A is removed from the rear housing 14B. A connection surface between the front housing 14A and the rear housing 14B is flat, and a waterproof portion 15 is provided to prevent liquid from entering the housing 14. As shown in FIG. For example, a partition wall and packing rubber are arranged in the waterproof portion 15 .

5A and 5B are diagrams showing the arrangement of equipment inside the housing of the camera section, FIG. 5A being a perspective view seen from the front, and FIG. 5B being a perspective view seen from the rear. Note that the rear housing 14B is omitted.
The camera module 12 and the control board 13 are connected by a flexible flat cable 16 .
A rectangular control plate 13 is laid down above the camera module 12 . The flat cable 16 is arranged in a folded state between the camera module 12 and the control plate 13 .
In this way, the control board 13 is laid down facing the camera module 12, and the flat cable 16 is arranged between the camera module 12 and the control board 13. It is possible to reduce the size by keeping the height low. As a result, contact with accessories such as headlights arranged on the front surface of the cap body 101 can be avoided.

In addition, since the camera module 12, the control plate 13, and the flat cable 16 are housed in the housing 14 provided with the waterproof section 15, the helmet camera 1 can be used outdoors where it is exposed to wind and rain. can.

In addition, since the control plate 13 is arranged above the camera module 12, as shown in FIG. Visibility can be secured.

6A and 6B are enlarged views of the attachment portion of the helmet camera in the helmet, FIG. 6A is a perspective view seen from the left, FIG. c) is a perspective view from above. FIG. 7 is a top view showing a helmet to which a helmet camera is attached.
The mounting portion 20 is coupled to the periphery of the canopy 102 .
The mounting portion 20 includes a canopy connecting portion 21 and a camera holding portion 22 . By connecting the eaves connecting portion 21 to the peripheral edge of the eaves 102 of the helmet 100 , the mounting portion 20 can be fixed to the eaves 102 . Further, the camera section 10 housed in the housing 14 is attached to the camera holding section 22 . The camera holding portion 22 is connected to the canopy connecting portion 21 .

The eaves connecting portion 21 is bifurcated and includes one eaves connecting portion 21 and the other eaves connecting portion 21 .
One eaves connecting portion 21 and the other eaves connecting portion 21 are connected by a bridging portion 23 that spans over the upper portion. Since one eaves connection part 21 and the other eaves connection part 21 are connected via a bridge part 23, the eaves connection part 21 can be integrally attached to and detached from the eaves 102, improving workability. do.

The eaves connecting portion 21 includes an upper surface placement portion 21A arranged on the upper surface of the eaves 102, a lower surface placement portion 21B arranged on the lower surface of the eaves 102, and a tip placement portion 21C arranged at the tip of the eaves 102. The upper surface placement portion 21A and the lower surface placement portion 21B are connected via the tip placement portion 21C.
Since the eaves connection part 21 includes the upper surface arrangement part 21A in contact with the upper surface of the eaves 102, the lower surface arrangement part 21B in contact with the lower surface of the eaves 102, and the tip arrangement part 21C in contact with the tip of the eaves 102, the eaves 102 and the eaves 102 are firmly connected. , and is less likely to swing or shift due to vibration, impact, or the like.

The eaves connection part 21 is a thin plate-like leaf spring, and is bent at a tip end placement part 21C by 180 degrees so that the eaves 102 can be sandwiched therebetween, and the top face placement part 21A and the bottom face placement part 21B face each other. is formed in At least a portion of the distance between the upper surface placement portion 21A and the lower surface placement portion 21B is smaller than the thickness of the eaves 102 .
By making the eaves connecting portion 21 a leaf spring, the eaves connecting portion 21 can firmly sandwich the eaves 102 by its own elasticity. Therefore, compared with the case where the upper surface arrangement portion 21A and the lower surface arrangement portion 21B are connected by a coil spring or the like, the configuration of the eaves connecting portion 21 can be simplified and the size thereof can be reduced.

When connecting the eaves connecting portion 21 to the eaves 102, the eaves 102 is sandwiched between the upper surface placement portion 21A and the lower surface placement portion 21B. Although there is a portion where the distance between the upper surface arrangement portion 21A and the lower surface arrangement portion 21B is smaller than the thickness of the eaves 102, the eaves connecting portion 21 has elasticity, so the distance is smaller than the thickness of the eaves 102. The portion is expanded from the inside by a canopy 102 inserted between the upper surface placement portion 21A and the lower surface placement portion 21B.
The eaves connection portion 21 with the eaves 102 sandwiched therebetween presses the upper and lower surfaces of the eaves 102 by the restoring force of the leaf spring, especially in the portion where the distance between the upper surface arrangement portion 21A and the lower surface arrangement portion 21B is smaller than the thickness of the eaves 102. Therefore, even if an external force such as vibration or impact is applied, positional deviation is suppressed.

In general, the eaves 102 of the helmet 100 do not protrude linearly from the cap body 101 to the edge, but protrude curved from the cap body 101 to the edge. Therefore, when a piece of flat leaf spring is folded back 180 degrees at the tip placement portion to form the eaves connecting portion, and the eaves connecting portion is used to sandwich the eaves 102, the upper surface of the eaves connecting portion is arranged. Since there is a gap between the part and the lower surface arrangement part and the eaves 102, surface contact does not occur, and point contact occurs at one point on the upper surface side and one point on the lower surface side, and when vibration or shock is applied. Rotation and misalignment are likely to occur at the connecting part of the eaves. Further, even if the shape of the eaves connecting portion is formed according to the degree of curvature of the eaves, it is difficult to eliminate the gaps between the upper surface arrangement portion and the lower surface arrangement portion and the eaves 102 . In addition, since the degree of curvature of the eaves 102 varies depending on the helmet 100, if the eaves connection portion is formed according to the degree of curvature of the eaves 102, the versatility of the helmet camera 1 is lost and the manufacturing cost increases. issues arise.
In general, the canopy 102 of the helmet 100 is formed in an arc shape when viewed from above. Therefore, when a piece of flat leaf spring is folded back 180 degrees at the tip arrangement portion to form the eaves connection portion, and the eaves connection portion is used to sandwich the central portion of the eaves 102, the eaves connection portion The tip placement portion of 1 abuts only the most protruding portion of the eaves 102, and in other portions, a gap is generated between the tip placement portion and the tip of the eaves 102, so when vibration or impact is applied, Owing and displacement are likely to occur at the connecting part of the eaves. If the eaves connection portion is formed in accordance with the shape of the eaves 102, problems such as loss of versatility of the helmet camera 1 and increase in manufacturing cost arise similarly to the above.
Therefore, in the present embodiment, the eaves connecting portion 21 is bifurcated as described above. By providing one eaves connecting portion 21 and the other eaves connecting portion 21, two-point contact (one point on the upper surface side, one point on the lower surface side) at one eaves connecting portion 21 and two-point contact at the other eaves connecting portion 21 (1 point on the upper surface side, 1 point on the lower surface side), a total of 4 points of contact. Since the contact area is increased by increasing the number of contact points, the eaves connecting portion 21 can be more firmly coupled to the eaves 102 . Furthermore, by bifurcating the eaves connecting portion 21, the most protruding portion of the eaves 102 is bypassed, and the tip placement portion is formed on both sides of the eaves connecting portion 21 (one eaves connecting portion 21 and the other eaves connecting portion 21). 21C can be brought into contact with the eaves 102 reliably. As a result, positional deviation is less likely to occur even when vibration, impact, or the like is applied. Further, since the coupling becomes firm, the eaves connection part 21 does not need to be so long, so by shortening the eaves connection part 21, the helmet camera 1 can be attached even to a helmet with a relatively short eaves. can be done.

In addition, the upper surface arrangement portion 21A of the eaves connection portion 21 in this embodiment is generally linear, and the open end side thereof is curved in a direction away from the lower surface arrangement portion 21B. In addition, after the lower surface placement portion 21B is curved in a direction approaching the upper surface placement portion 21A from the tip placement portion 21C side (folding side), the distance between the upper surface placement portion 21A and the lower surface placement portion 21B is smaller than the thickness of the eaves 102. With the curved portion as a boundary, the shape is curved toward the open end side in a direction away from the upper surface placement portion 21A. That is, the eaves connecting portion 21 is formed in a substantially R shape. With this shape, the upper surface placement portion 21A and the lower surface placement portion 21B can be joined to the eaves 102 more firmly.
A portion of the lower surface placement portion 21B where the distance between the upper surface placement portion 21A and the lower surface placement portion 21B is smaller than the thickness of the eaves 102 is preferably covered with a non-slip material such as rubber. By providing the non-slip material, the frictional force between the lower surface of the eaves 102 and the lower surface arrangement portion 21B is increased, and the eaves connection portion 21 can be prevented from swinging or being displaced due to vibration, impact, or the like.

As shown in FIG. 7, in a state in which eaves connecting portion 21 is coupled to the central portion of eaves 102, one eaves connecting portion 21 and the other eaves connecting portion 21 are symmetrical about the central portion of eaves 102. Located in The length X from the outer surface of one eaves connecting portion 21 to the outer surface of the other eaves connecting portion 21 is between 15% and 30% of the length P from one side of the helmet 100 to the other side. and
Also, the distance Y between one eaves connecting portion 21 and the other eaves connecting portion 21 is smaller than the width Z of the area of the housing 14 excluding the portion where the main body connection cable 2 is disposed inside. In addition, the length X from the outer surface of one eaves connecting portion 21 to the outer surface of the other eaves connecting portion 21 is also the width of the area of the housing 14 excluding the portion where the main body connection cable 2 is arranged inside. smaller than Z. The interval Y is preferably 60% or more and 70% or less of the width Z, and the length X is preferably 80% or more and 95% or less of the width Z.
By reducing the size of the eaves connection part 21 in this way, the possibility of the eaves connection part 21 coming into contact with an obstacle or the like can be reduced, and the weight of the entire mounting part 20 can be reduced to reduce the burden on the wearer. be able to.

The camera holding portion 22 is bifurcated and includes one camera holding portion 22 and the other camera holding portion 22 . One camera holding part 22 and the other camera holding part 22 are arranged between one eaves connection part 21 and the other eaves connection part 21 , and one camera holding part 22 is located between one eaves connection part 21 , and the other camera holding portion 22 is adjacent to the other eaves connecting portion 21 .
The camera holding portion 22 is provided in a state inclined forward and upward with the rear end fixed to the upper surface of the bridge portion 23 as a base point, and the tip is arranged to protrude forward from the eaves 102 . The camera section 10 is held at the tip of the camera holding section 22 so as to be rotatable up and down around the connecting section with the camera holding section 22 .

As shown in FIGS. 6 and 7, the camera section 10 is held by one camera holding section 22 and the other camera holding section 22, so that the camera section 10 is held by a single camera holding section 22. Since the rocking motion of the camera unit 10 is suppressed, it is possible to reduce blurring during shooting.
Further, in order to increase the vertical rotation range of the camera unit 10, it is necessary to arrange the camera unit 10 in front of the eaves 102 to avoid interference with the eaves 102. When the horizontal distance between the .theta. Therefore, by providing the camera holding portion 22 in a state inclined forward and upward with the rear end fixed to the upper surface of the bridge portion 23 as a base point, and arranging the camera portion 10 to protrude forward and upward from the eaves 102, the camera holding portion 22 is horizontally provided with the rear end fixed to the upper surface of the bridge portion 23 as a base point, and the horizontal distance between the canopy 102 and the camera portion 10 is made smaller than in the case where the camera portion 10 is projected horizontally in front of the canopy 102, Swinging of the camera section 10 can be suppressed.

8A and 8B are diagrams showing the rotation operation of the camera section, FIG. 8A being a side view and FIG. 8B being a rear view.
FIG. 8A shows a state in which the camera section 10 is rotated upward from the horizontal direction and a state in which it is rotated downward. FIG. 8B shows a state in which the camera section 10 is rotated upward from the horizontal direction.
As described above, since the distance between one eaves connecting portion 21 and the other eaves connecting portion 21 is set to be larger than the width of the housing 14, when the camera portion 10 is rotated downward, the eaves connecting portion 21 doesn't get in the way. Therefore, the downward rotation range of the camera section 10 can be increased. In addition, when the camera section 10 is rotated downward, the camera section 10 is accommodated between one eaves connecting portion 21 and the other eaves connecting portion 21 .
Since the camera unit 10 can be rotated vertically, the wearer can arbitrarily change the vertical position of the camera unit 10 according to the position of the object to be photographed, the work situation, and the like.
