AI Technical Summary
Conventional human presence sensor voice alarms with a simple rectangular parallelepiped box shape struggle to be effectively attached to surfaces with complex curved shapes, such as the body of heavy machinery, lacking the ability to find the most appropriate attachment location.
The human presence sensor voice alarm features a case with protruding legs and movable magnets supported by springs, allowing it to conform to complex curved surfaces by attaching to them via magnets, even when the surface is not flat.
The design enables secure and optimal attachment to objects with significant curvature changes, ensuring effective placement on surfaces like heavy machinery.

Summary of the Invention
Problems to be Solved by the Invention
[0004] However, since the case of the conventional human presence sensor voice alarm has a simple rectangular parallelepiped box shape, when it is desired to attach it to an attachment target having a complex curved surface shape with a large change in curvature depending on the location rather than a flat surface like the body of a heavy machine, it is difficult to attach the case to the most appropriate location.
[0005] The present invention has been made in view of such conventional circumstances, and one of the objects of the present invention is to provide a human presence sensor voice alarm that can be attached to an object having a complex curved surface shape with a large change in curvature, such as the body of a heavy machine, at the most appropriate location.
[0006] Still other objects of the present invention will become apparent from the following description.
Means for Solving the Problems
[0007] The human presence sensor voice alarm according to the present invention as claimed in claim 1 comprises a human body detection sensor for detecting the approach of a person, a voice storage unit in which voice messages are stored, a speaker for outputting the voice messages of the voice storage unit, a control unit for causing the speaker to output the voice messages of the voice storage unit when the approach of a person is detected by the human body detection sensor, and a case for housing the human body detection sensor, the voice storage unit, the speaker, and the control unit. In the human presence sensor voice alarm, the case has a central side portion, legs provided at both ends of the central side portion and protruding rearward from the central side portion, both End are respectively provided on the rear surface sides of the legs, and have magnets that are adsorbed to the surface to which the human presence sensor voice alarm is to be attached. , The magnet is movably supported between a state of being housed in the leg portions at both ends and a state of protruding from the leg portions to the outside within the leg portions. It further has springs that bias the magnets in directions to be housed in the leg portions, respectively.
[0008] According to the present invention as claimed in claim 1, since the case does not have a simple rectangular parallelepiped box shape as in the prior art, but has a shape in which legs protrude rearward from both ends of the central side portion, it can be attached to the most appropriate location even for an object having a complex curved surface shape with a large change in curvature depending on the location, such as the body of a heavy machine.
[0009] Also, The magnets are movably supported on the legs on both sides between a state of being housed in the legs and a state of protruding from the legs to the outside, and have springs for biasing the magnets in a direction of being housed in the legs respectively. Therefore, it can also cope with an object having a more complex curved surface shape with a larger change in curvature.
Effects of the Invention
[0011] The human presence sensor voice alarm of the present invention can achieve excellent effects such as being able to be attached to an object having a complex curved surface shape such as the body of a heavy machine at the most appropriate location.

Modes for Carrying Out the Invention
[0013] Hereinafter, the present invention will be described based on the embodiments shown in the drawings.
Embodiment
[0014] Figs. 1 to 11 show an embodiment of the present invention. The case 1 of the human presence sensor voice alarm shown in Figs. 1 to 10 is made of plastic and has a central side portion 1a and leg portions 1b provided at both left and right ends of the central side portion 1a and protruding rearward from the central side portion 1a.
[0015] At the rear center of the central portion 1a of the case 1, a cylindrical portion 1a1 (see FIG. 8) is integrally provided, and a lid portion 1c is removably screwed onto the cylindrical portion 1a1.
[0016] The control system shown in FIG. 11 is accommodated in the case 1. The control system in FIG. 11 is the same as the conventional control system, and includes a human body detection sensor 2 for detecting the approach of a person, an audio storage unit 3 in which an audio message is stored, an audio message stored in the audio storage unit 3 is input via an amplifier 4, and a speaker 5 for outputting the audio message, and an output of the human body detection sensor 2 is input via an amplification unit 6, and a control unit 7 for controlling the audio storage unit 3.
[0017] A circular sensor cover 8 is attached to the center of the front surface of the case 1. The human body detection sensor 2 shown in FIG. 11 is provided in the case 1 so as to be located immediately behind the sensor cover 8. The sensor cover 8 is made of a material that does not interfere with the function of the human body detection sensor 2.
[0018] As shown in FIGS. 7, 9, and 10, three magnets 10 are supported on the both side legs 1b so as to be movable between a state of being accommodated in the legs 1b and a state of protruding from the legs 1b to the outside. Each magnet 10 is biased by a spring 11 in a direction to be pulled into the leg 1b.
[0019] A switch 13 for turning on and off the control system in FIG. 11 is provided on the front surface of the case 1.
[0020] During manufacturing, as well shown in FIGS. 1, 3, and 4, etc., the case 1 is divided into a front side portion 1d and a rear side portion 1e, and after various components are mounted inside the case 1, they are joined to each other and integrated.
[0021] This human body detection sensor voice alarm can be easily attached to an attachment target such as construction machinery by attracting the magnet 10 to the attachment target. And since the case 1 has a central portion 1a and leg portions 1b provided at both ends of the central portion 1a and protruding rearward from the central portion 1a, it can be attached even if the attachment surface 12 is not flat but curved as well shown in Fig. 5.
[0022] Furthermore, in this human body detection sensor voice alarm, the magnet 10 can be accommodated in the main body 2 as shown in Fig. 9 or protrude from the main body 2 as shown in Fig. 10. Therefore, the magnet 10 can be attracted to adapt to various curved surfaces of the attachment target such as construction machinery, and thus it can correspond to various curved surfaces (attachment surfaces 12) of the attachment target such as construction machinery.
Industrial Applicability
[0023] As described above, the human body detection sensor voice alarm according to the present invention can be attracted to adapt to various curved surfaces of the attachment target such as construction machinery, and is useful.
