Definitions
- the present invention relates to a hood of head protection and more particularly a hood of which a part corresponding to the face (comprising the eyes, nose and mouth) can be cleared quickly.
- hoods are used to protect functions vital against contamination in activities in aggressive media: gas or liquid projection or oxygen-poor atmosphere for example.
- hoods are generally waterproof. If necessary, a slight overpressure inside prevents any entry of gas from outside, which could pass by imperfect seals.
- the fixing can of course be applied to any removable part of the hood, either in front of the face of the bearer, or any other party.
- removable part is used here with a general sense and can correspond to any removable area of the hood, with or without breathing apparatus or other listening devices, vision, etc.
- the distance between the button head and the hole transverse is chosen so that after placing the wire, the two thicknesses of the edge of the hood opening and the edge of the removable part are compressed, or held tight against each other.
- the device has two wires both attached to a single ring, a first wire crossing part of the buttons, and second thread crossing the other buttons.
- the ends of the first and second wire lie side by side between two buttons, and are covered with a tubular element so that a withdrawal wires due to a pull on the ring releases said element tubular.
- the hood 1 shown in Figure 1 is of a type used for the protection of vital functions (sight, hearing, nose, mouth, skin) for people performing activity in an aggressive environment (firefighter, chemist, military, etc.).
- a zone has been indicated in 2 which will be designated below.
- removable part for convenience of description. In general, this is the part covering the face. he may have a transparent part for the view, possibly devices to assist breathing or hearing.
- this removable part is separable from the hood.
- a other area is removable. This can be done from different ways: snaps, closure slide, etc.
- the subject of the invention is a fixing removable, allowing to obtain a safety suit when the removable part must be in place, a seal sufficient and removal as quickly as possible, practice instant removal.
- the invention applies to any form of hood, which you want to remove quickly and easily a specific area, regardless of its location and whatever accessories it may be stocked.
- Each end has a barrel fitted with a end of an enlarged flat head 3B and a hole 3A formed transversely in the vicinity of the end opposite the head.
- the button heads can form a ribbon 35 which thus makes the buttons integral, avoids losing them and facilitates installation.
- the 3B head of each button is placed inside the hood and the edge of the removable part is placed on the outside of the hood.
- the gap between the head and the hole 3A is chosen so that the hole appears outside the edge of the removable part 2 leaving a free section equal in height, or slightly less than the diameter of the wire 4.
- This wire 4 is preferably a fairly stiff wire, for example metallic example. It will therefore be necessary to tighten the thicknesses the edge of the hood and the edge of the removable part to engage wire 4 in hole 3A.
- the seal 11 having a certain elasticity will facilitate this operation and maintain a permanent clamping pressure between the edge of the opening of the hood and the edge of the removable part. This pressure is sufficient to seal in many applications. The tightness will be all the better as the buttons will be closer to each other. We can also maintain some overpressure inside the hood, to safely prevent any air entry from outside.
- the seal may include a rigid part to ensure better clamping distribution.
- the edge of the game removable can also be reinforced or stiffened depending on the nature of this removable part.
- Figure 4 shows an overview fixing the removable part 2 to the hood 1, outside front view. So we see the ends of the buttons. In this attachment, two strands of wire were placed: a first wire 41 and a second wire 42. The wires between the buttons. The two wires are attached to a ring 5, and each pass through half of the total of buttons 3. It So just pull on the ring 5, and the removable part is instantly released and released from the hood.
- the ring can be attached to the hood or simply removable part: press button, for example.
- the 41A end of the wire 41 is engaged until button 31, and we choose the length wire 41 so that it substantially exceeds button 31, by example up to the vicinity of the next button 32.
- a small tube 6 is placed between the buttons 31 and 32 to receive the ends 41A and 42A of the two sons 41 and 42. As soon as we start shooting ring 5, the tube is released and falls.
