Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a full-face mask used for dust masks, gas masks, air-supply masks, self-contained respirators and the like. The present invention relates to a full-sized facepiece with a small camera, which is capable of monitoring a dangerous spot being performed outside the spot.

[0002]

2. Description of the Related Art Heretofore, a person carrying out a rescue operation while entering a dangerous site by wearing a full-face mask and a supervisor who is away from the site of the rescue operation and gives various instructions. Communication with each other during the operation is based on a report on the situation of the site by voice sent from a person at the activity site wearing a full facepiece equipped with a voice or microphone and a receiver, and supervision performed based on the report. The supervisor did not visually observe the situation at the site of the rescue operation. By the way, in order to supply the situation of the site such as the rescue activity as visual information to the supervisor, it is conceivable to bring the camera to the site with a hand, but in that case, it is necessary to bring the camera to the site where the use environment is poor. It is necessary to design the camera in advance, the handling of the camera is not good, and a person carrying the camera cannot expect a sufficient rescue operation. It is also conceivable to attach a camera to the outside or the helmet of the rescuer's full facepiece,
Also in this case, it is necessary to design the camera so that it can be brought to a site where the use environment is poor such as a rescue site, and the camera is located far away from the viewpoint (eye position) of the rescue worker. A gap occurs between the point on the site viewed by the rescue worker and the image of the site viewed by the supervisor from the monitor.

[0003] In addition, even when a report on the situation at the dangerous site is made after a rescue operation or the like is completed, it is necessary to rely on the recording of communication from the site and the memory of the site activist. Accordingly, the grasp and analysis of the site situation become insufficient, and the collection of materials for improving the manual of the site activity in the similar situation in the future becomes insufficient.

[0004]

Therefore, the present inventor does not need any special means for protecting the camera from a dangerous site environment unlike the conventional camera means, and rescues the camera at the dangerous site. The present inventor has studied diligently how to transmit the information for grasping the situation of the site such as the activity as visual image information to the supervisor outside the site. That is, an object of the present invention is to provide information for grasping the situation of a site such as a rescue operation at the dangerous site without requiring any special means for protecting the camera from a dangerous site environment unlike the conventional camera means. Is to be transmitted as visual image information to a supervisor outside the site.

[0005]

SUMMARY OF THE INVENTION The gist of the present invention is a camera-equipped full-surface body having a small camera mounted inside the body, which provides extra camera protection means as in the conventional camera means. In this case, the small camera is arranged so as to be shielded from a dangerous site environment. As a structure of the means (camera mounting member) for mounting the small camera in the plane, specifically, a fixing means such as an adhesive means, an adhesive means, or a vacuum suction means can be adopted for the eyepiece of the small camera. The elastic member (a member such as rubber) constituting the face is connected to the eye frame (F.
L) A small camera mounting means made of an elastic piece, for example, a rubber piece, for holding the small camera by elasticity is provided on the side to be attached to L). Small camera mounting means consisting of a cylindrical camera mounting frame (FF) is provided, or is held by the spring force inside the eye frame (spring force trying to expand inside the eye frame), at the center of the member (near the eyebrows) A small camera mounting structure such as providing a small camera mounting member for holding the small camera by the rectangular cylindrical camera mounting frame or elastic piece for mounting the small camera, and providing a small camera mounting member detachable from the face. Adopting this is preferable because the small camera can be more stably fixed in the plane. As the miniature camera, specifically, a microminiature camera used for creating a video camera, a video mail, or the like is attached to the main body to form a full-face main body with a camera.

[0006] Further, a means for converting an image obtained by the small camera in the plane into a transmission signal and a means for transmitting the converted image signal to a monitor device where a supervisor outside the site is located are attached. With a small camera and a full face panel. In order to transmit a video signal obtained by a small camera to the monitor device, a conventional transmission method such as a wireless transmission method or a wired transmission method can be adopted. Attach the means to make a full-faced body with a camera. The wireless transmission means (transmission unit) can be provided in an appropriate space in the plane, for example, a space between the nose cup and the eyepiece. The inventor of the present invention has a camera-equipped full-surface body with a small camera mounted inside the plane body, so that there is no special means for protecting the camera from a dangerous environment, and the camera can be used by an off-site supervisor. The problem was solved by transmitting the status of activities such as rescue activities at dangerous sites as visual image information.

In FIG. 3, a small camera, which is provided on the side of the elastic member constituting the facepiece (FC) on which the facepiece is attached to the eye frame (FL), is pushed in the eyepiece direction to be attached. A configuration is shown in which the camera is mounted on a camera mounting frame, for example, a rectangular cylindrical camera mounting frame (FF). It is also possible to adopt a structure in which the mounting frame is fixed by sandwiching the small camera with an elastic member, for example, a rubber piece. The mounting member of the small camera C1 is such that when the small camera is attached, the small camera is located at a position close to the viewpoint of the face wearer so that the camera is fixed at an intermediate position between the eyes of the wearer (near the eyebrows). It is preferable that the configuration be held. In addition, the small camera can be fixed to the eyepiece (EP) by adhesion, adhesion, suction under reduced pressure (suction structure), or the like. With the configuration of the mounting member to which the small camera is fixed at the position, the supervisor's instruction to the face wearer based on the judgment of the monitor image can be easily understood.

Accordingly, the mounting member of the small camera is located inside the eyepiece in the upper central portion of the eye frame (FL) (near the eyebrows).
