[0009] Hereinafter, an embodiment of a safety tool according to the present disclosure will be described in detail with reference to the drawings.
[0010] In this specification, terms indicating a vertical relationship such as "upper", "upper", "lower", and "lower" are related to the height of the safety equipment from the installation surface at a construction site, etc., and are related to the vertical direction unless otherwise specified. In addition, the X direction, Y direction, and Z direction shown in each figure are shown for the purpose of defining the plane and direction of the safety equipment shown as an example, and the X direction, Y direction, and Z direction are mutually perpendicular and form a right-handed system. In each figure, the X direction and the Y direction are parallel to the installation surface (i.e., the XY plane is parallel to the installation surface). The Z direction is perpendicular to the installation surface, and the +Z direction is a direction that points further upward from the installation surface. In the following explanation, the Z direction may be referred to as the vertical direction. These directions and planes are terms used for convenience of explanation, and the corresponding relationship with each of the X direction, Y direction, and Z direction may change depending on the posture of the safety equipment.
[0011] In addition, the aspect ratios and the size relationships between the components in each drawing are merely schematic representations and do not necessarily correspond to the relationships in the safety equipment that is actually manufactured. For the sake of convenience of explanation, it is assumed that the size relationships between the components may be exaggerated.
[0012] Fig. 1 is an exploded perspective view for explaining a configuration example of a safety tool according to an embodiment. Fig. 2 is a top view for explaining a configuration example of a safety tool according to an embodiment. Fig. 3 is a cross-sectional side view for explaining a configuration example of a safety tool according to an embodiment. The cross-sectional side view of Fig. 3 is a view of the safety tool in which the cone-shaped cover, the electronic device mounting part, and the inner plug are cut along the line A-A' in Fig. 2, as viewed from the negative side in the Y direction.
[0013] The safety device 1 illustrated in FIGS. 1 to 3 includes a base 2, a cone-shaped cover 3, an electronic device mounting portion 4, and an inner plug 5. The safety device 1 illustrated in FIGS.
[0014] The base 2 is a flat plate-like member covering the lower end of the hollow cone-shaped cover 3, and may be, for example, a resin plate such as polyethylene, EVA (ethylene-vinyl acetate copolymer resin), soft polyvinyl chloride, or a metal plate such as stainless steel or aluminum. The cone-shaped cover 3 has a hollow truncated cone portion 300 with an outer shape of a truncated cone and an open top and bottom, and a fin portion (which may also be called a flange or brim portion) 310 extending radially outward from the bottom of the truncated cone portion 300. The cone-shaped cover 3 is formed of, for example, a resin. Instead of the cone-shaped cover 3, a cover having a hollow truncated cone portion with an outer shape of a polygonal truncated cone and an open top and bottom, and a fin portion 310 extending radially outward from the bottom of the truncated cone portion may be used.
[0015] The fin portion 310 of the cone-shaped cover 3 is formed with through holes 311, 312 penetrating in the axial direction of the truncated cone portion 300 (Z direction in FIG. 1), and screw holes 211, 212 are formed at positions overlapping with the through holes 311, 312 of the cone-shaped cover 3 on the upper surface 201 of the base 2. The shafts of bolts 611, 612 inserted into the through holes 311, 312 of the cone-shaped cover 3 are screwed into the screw holes 211, 212 of the base 2, whereby the cone-shaped cover 3 is attached to the base 2. The number of pairs of the through holes of the cone-shaped cover 3 and the screw holes of the base 2 used to attach the cone-shaped cover 3 to the base 2 is not limited to a specific number. In addition, the method of attaching the cone-shaped cover 3 to the base 2 is not limited to the method of using the bolts described above.
[0016] A storage battery 701, a PoE (Power over Ethernet) hub 702, a wireless communication device 703, and a relay 704 are disposed in a hollow portion surrounded by the upper surface 201 of the base 2 and the truncated cone portion 300 of the cone-shaped cover 3. The storage battery 701, the PoE hub 702, the wireless communication device 703, and the relay 704 are integrally held by, for example, a metal plate 710 coupled to the upper surface 201 of the base 2. The positional relationship of the storage battery 701, the PoE hub 702, the wireless communication device 703, and the relay 704 disposed in the hollow portion and the method of fixing them to the base 2 or the like are not limited to a specific positional relationship or a specific fixing method.
[0017] The fin portion 310 of the cone-shaped cover 3 has a notch 320 formed along the upper surface 201 of the base 2, which connects the hollow portion with the outside and allows a switch 705 to be attached to the upper surface 201 of the base 2. The switch 705 is connected to a relay 704, which is connected to a PoE hub 702 and a wireless communication device 703. The relay 704 may be a power supply control device that controls the on / off of the power supplies of the PoE hub 702 and the wireless communication device 703, and is also connected to the storage battery 701. When the switch 705 is turned on, power is supplied from the storage battery 701 to the PoE hub 702 and the wireless communication device 703 via the relay 704, and the PoE hub 702 and the wireless communication device 703 are turned on (operated). Furthermore, electronic devices such as cameras 801-805 attached to electronic device mounting section 4, which will be described later, are connected to PoE hub 702 via LAN (Local Area Network) cables 711-713, and operate with power supplied from PoE hub 702 via LAN cables 711-713. When switch 705 is disposed on upper surface 201 of base 2 located at the lower end of safety equipment 1 as illustrated in Fig. 1 and Fig. 3, switch 705 can be turned on and off with a foot, for example, and the burden on workers, etc., associated with operating switch 705 is reduced.
[0018] The electronic device mounting part 4 is attached to the top of the truncated cone part 300 of the cone-shaped cover 3. The electronic device mounting part 4 is fixed to the top of the truncated cone part 300 by screwing it to the inner plug 5 arranged in the hollow part of the truncated cone part 300 of the cone-shaped cover 3. The inner plug 5 is made of an elastic material such as resin or rubber, and has a truncated cone (trapezoid of revolution) shape that can block the opening on the top side of the truncated cone part 300 from the hollow part side. The electronic device mounting part 4 and the inner plug 5 have through holes formed so that the hollow part of the truncated cone part 300 communicates with the outside when they are attached to the top of the truncated cone part 300 of the cone-shaped cover 3. The other ends of the LAN cables 711 to 713, one end of which is connected to the PoE hub 702, are pulled out to the outside of the safety equipment 1 through the through holes formed in the electronic device mounting part 4 and the inner plug 5. By fitting the inner plug 5 into the truncated cone portion 300 in the hollow portion, the mounting position of the electronic device mounting portion 4 is stabilized, and it is possible to prevent foreign matter (e.g., dust, insects, moisture, etc.) from entering the hollow portion from the opening on the upper side of the truncated cone portion 300. The inner plug 5 is not limited to a shape in which the position of its upper end surface coincides with the position of the upper end surface of the cone-shaped cover 3 as illustrated in FIG. 3, but may have a shape in which its upper end portion protrudes above the upper end surface of the cone-shaped cover 3.
[0019] 1 to 3 has mounting mechanisms 401-404 capable of mounting electronic devices such as cameras 801-804 in four radially outward directions from the truncated cone portion 300 of the cone-shaped cover 3, and a mounting mechanism 405 capable of mounting electronic devices such as a camera 805 above the truncated cone portion 300. The configurations of the electronic device mounting portion 4 and the inner plug 5 will be described in further detail with reference to FIG.
[0020] FIG. 4 is an exploded cross-sectional side view illustrating a configuration example of an electronic device attachment portion in a safety device according to one embodiment.
[0021] The electronic device attachment section 4 illustrated in FIGS. 1 to 4 includes a lower adaptor 410 having four attachment mechanisms 401 to 404 and an upper adaptor 420 having one attachment mechanism 405. The electronic device attachment section 4 illustrated in FIGS.
[0022] The lower adapter 410 includes an upper plate 411, a lower plate 412, and support plates 413-416. The upper plate 411, the lower plate 412, and the support plates 413-416 may be metal plates such as stainless steel or aluminum. The support plates 413-416 are disposed between the upper plate 411 and the lower plate 412, and allow the mounting mechanisms 401-404 to be mounted in such a manner that the elevation and depression angles of the cameras 801-804 mounted on the mounting mechanisms 401-404 in the direction of the imaging center can be changed. The support plates 413-416 are joined to the upper plate 411 and the lower plate 412, respectively, by, for example, welding, joining using a joining material, or caulking. The upper plate 411 is formed with a through hole 431 through which the shaft of a screw 613 used to screw the electronic device mounting part 4 to the inner plug 5 is inserted, and through holes 432, 433 through which the shafts of screws 614, 615 used to screw the lower adaptor 410 and the upper adaptor 420 are inserted. The lower plate 412 is formed with an opening 434 that allows the entrance of the apex of the truncated cone part 300 of the cone-shaped cover 3 when the electronic device mounting part 4 is screwed to the inner plug 5.
[0023] The upper adaptor 420 includes a support plate 421 that also serves as an attachment mechanism 405, and columnar members 422, 423 provided on the lower surface of the support plate 421. The support plate 421 may be, for example, a metal plate such as stainless steel or aluminum provided with an attachment mechanism 405 such as a camera head. The attachment mechanism 405 is configured to allow an electronic device such as a camera 805 to be attached to the upper surface of the support plate 421. The columnar members 422, 423 may be, for example, metal rods such as stainless steel or aluminum with screw holes formed at the lower ends. The columnar members 422, 423 are joined to the support plate 421 by, for example, welding, joining using a joining material, or caulking. The columnar members 422, 423 are joined to the support plate 421 so that the positions of the screw holes at the lower ends overlap with the through holes 432, 433 formed in the upper plate 411 of the lower adaptor 410.
[0024] The electronic device mounting section 4 described above with reference to Figs. 1 to 4 is merely an example of an electronic device mounting section capable of mounting a plurality of types of electronic devices. The number of electronic devices mountable to the electronic device mounting section 4 and the configuration of the mounting mechanism are not limited to a specific number or configuration. For example, the mounting mechanisms 401 to 404 mounted on the support plates 413 to 416 of the lower adapter 410 may be suitable for mounting a camera, such as a camera platform, and may be detachable from the support plates 413 to 416. The support plates 413 to 416 may be configured to be capable of detachably mounting mounting mechanisms suitable for mounting other electronic devices, instead of the mounting mechanisms 401 to 404 suitable for mounting a camera. Also, auxiliary parts (attachments) may be attached to the mounting mechanisms 401 to 404 to allow electronic devices other than cameras to be mounted on the mounting mechanisms 401 to 404.
[0025] In the safety tool 1 of the present embodiment, for example, four cameras 801-804 that take pictures in the radially outward direction from the cone-shaped cover 3 and a 360-degree camera 805 such as a celestial sphere camera can be attached to the electronic device mounting part 4. The 360-degree camera 805 is attached to the upper adapter 420 of the electronic device mounting part 4 so that the direction of the center of the image is oriented upward in the axial direction of the cone-shaped cover 3. For this reason, the 360-degree camera 805 cannot take pictures of the installation surface 20 (see FIG. 3) on which the safety tool 1 is installed, and it is difficult to use the 360-degree camera 805 for purposes such as detecting and avoiding the possibility of a worker falling in advance based on the state of the installation surface 20. In contrast, in the safety tool 1 of the present embodiment, the state of the installation surface 20 on which the safety tool 1 is installed can be photographed by the four cameras 801-804 that take pictures in the radially outward direction from the cone-shaped cover 3 and are attached to the lower adapter 410 of the electronic device mounting part 4. For this reason, the safety equipment 1 of this embodiment can be used, for example, as a road cone using the cone-shaped cover 3 (for regulating or dividing an area on site), and for monitoring the movements of people and objects on site using images captured by camera 805, as well as for preventing accidents using images captured by cameras 801-804.
[0026] FIG. 5 is a block diagram illustrating a configuration example of a camera system using a security tool according to an embodiment.
[0027] The camera system 9 illustrated in FIG. 5 includes five cameras 801 to 805, a storage battery 701, a PoE hub 702, a wireless communication device 703, a relay 704, and a switch 705.
[0028] As described above, the relay 704 may be a power supply control device that switches the power supply of the PoE hub 702 and the wireless communication device 703 on and off, and is connected to the PoE hub 702, the wireless communication device 703, and the storage battery 701. The relay 704 is also connected to the switch 705. When the switch 705 is turned on, power is supplied from the storage battery 701 to the PoE hub 702 and the wireless communication device 703 via the relay 704, and the PoE hub 702 and the wireless communication device 703 are turned on (operated).
[0029] The five cameras 801-805 are connected to the PoE hub 702 by LAN cables, and capture images using power supplied from the PoE hub 702 via the LAN cables. Videos or images captured by each of the cameras 801-805 are transferred to the wireless communication device 703 via the LAN cables and the PoE hub 702, and then converted (modulated) from an electrical signal to a wireless signal by the wireless communication device 703 and radiated. The wireless signal radiated from the wireless communication device 703 is received by the repeater 10, converted (demodulated) to an electrical signal, and transferred to the terminal 11. The terminal 11 may be, for example, an information processing device such as a computer used for monitoring and safety management of a site where the security tool 1 as the camera system 9 is installed. The repeater 10 and the terminal 11 may be connected via a communication network such as the Internet. Wireless communication between the wireless communication device 703 of the camera system 9 and the repeater 10 may be performed according to a known wireless communication standard. The repeater 10 may be connected to a communication network such as the Internet, and may perform wireless communication with the wireless communication device 703 in accordance with a wireless communication standard such as Wi-Fi (registered trademark) or Bluetooth (registered trademark).
[0030] When the camera system 9 illustrated in FIG. 5 is installed at a construction site or the like, up until now, several cameras have been installed using tripods or the like as separate from the safety equipment. The cameras installed at the site as separate from the safety equipment may give workers a sense of foreignness, hinder work, or be removed from the site. In contrast, the safety equipment 1 of this embodiment can provide the camera system 9 including the five cameras 801-805 illustrated in FIG. 5 as a single safety equipment. In addition, the safety equipment 1 of this embodiment has other hardware other than the five cameras 801-805 and the switch 705 arranged in a hollow portion formed by the base 2 and the cone-shaped cover 3 so as not to be seen by workers. Furthermore, since the cameras 801-805, the wireless communication device 703, and the like are operated by the storage battery 701, there is no need to lay cables for power supply or communication on the installation surface of the safety equipment. Therefore, the safety equipment 1 of this embodiment can reduce the sense of foreignness given to workers and the like.
[0031] Furthermore, at construction sites and other such sites, the installation positions of the cameras are changed according to the progress of work. For this reason, when some of the cameras in the camera system 9 illustrated in FIG. 5 are installed at the site separately from the safety tools, it takes time to move the cameras and the safety tools. With the safety tool 1 of this embodiment, the entire camera system 9 can be easily moved simply by moving the safety tool 1 within the site. Moreover, the safety tool 1 of this embodiment has rollers (casters) 220 attached to the side of the base 2 that can be used to move the safety tool 1, for example, as illustrated in FIGS. 2 and 3.
[0032] FIG. 6 is a side view illustrating a method of moving a safety tool according to one embodiment.
[0033] As described above, the safety equipment 1 of this embodiment includes the storage battery 701, the PoE hub 702, the wireless communication device 703, etc., and is heavier than a typical road cone. For this reason, when moving the safety equipment 1 of this embodiment, as illustrated in Fig. 6, the safety equipment 1 is tilted so that the base 2 is lifted off the installation surface 20 with the rollers 220 attached to the side of the base 2 as fulcrums, and the rollers 220 are rotated to move the safety equipment 1. In this way, the safety equipment 1 can be moved with less force than when the entire safety equipment 1 is lifted off the installation surface 20 and moved.
[0034] The present invention is not limited to the above-described embodiment, and may be modified, substituted, or altered in various ways without departing from the spirit of the technical idea. Furthermore, if the technical idea can be realized in a different way due to technological progress or a different derived technology, it may be implemented using that way. Therefore, the claims cover all embodiments that may be included within the scope of the technical idea.
[0035] For example, the electronic device mounting section 4 of the safety equipment 1 is not limited to a configuration that allows the above-mentioned multiple cameras 801 to 805 to be mounted, but may be configured to allow multiple types of electronic devices to be mounted (for example, two or more types of electronic devices selected from electronic devices that can be installed at a construction site, such as a camera, a speaker, a lighting fixture, and a warning light). The multiple types of cameras mounted on the electronic device mounting section 4 may include, for example, a camera that captures visible light images and a camera that captures infrared images. The electronic devices that can be mounted on the electronic device mounting section 4 may include sensors such as an environmental sensor that detects information about the environment, such as temperature, humidity, and noise level, and a human sensor. The supply of power from the storage battery 701 to the electronic devices is not limited to a supply method using the PoE hub 702 and a LAN cable, and may be other methods. Some of the electronic devices mounted on the electronic device mounting section 4 may have built-in batteries and be operated by the built-in batteries. The switch 705 is not limited to being installed on the upper surface 201 of the base 2, but may be installed at other positions, for example, in close proximity to the electronic device mounting section 4. The switch 705 and the relay 704 may be configured to be able to attach, for example, an adapter (plug) used for charging the storage battery 701, so that the storage battery 701 can be charged while the cone-shaped cover 3 is attached to the base 2.
