Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a helmet. In particular, the invention relates to such a helmet that can be specially used with an inhalation mask.

The type of helmet used by firefighters and police is
L, rriL must be used in conjunction with an inhalation mask, ie a face mask which is provided with a suitable air filter and supply and has clear vision lenses in front of the eyes.

The helmet typically includes an interior web assembly that supports the hard outer shell of the helmet that is not in full contact with the user's head.

Inhalation masks break up the legibility skirt, which snugly engages the user's contours and is usually held in place by the skirt's own thongs for an airtight seal.

Removal of the helmet, installation of the respirator, and deployment of the helmet are considered unacceptable, especially in the hazardous environments in which such assemblies are used.

This is because the helmet does not fit properly over the laces of the respirator. In particular, it has been proposed to shape the mask so that it can fit within the facial opening of a helmet, but no system is known that allows the helmet to safely fit an inhalation mask with which it is used over the full range of head dimensions. In addition, the procedures for putting on and taking off the inhalation mask were cumbersome.

Accordingly, it is an object of the present invention to provide an improved inhalation mask and helmet assembly.

Another object is to provide an inhalation mask and helmet assembly that overcomes the above-mentioned disadvantages, which can fit over the face of any user of the helmet.

The helmet according to the present invention has a right side part and a left side part, and a face notch opening in the M+] direction is formed between these side parts, and a neck opening opening downward in the lower part of both sides is formed. a rigid shell, a number of interconnected flexible radial strips having left and right ends converging at right and left positions, respectively, of the shell sides; The right and left anchor elements are generally provided on the right and left sides, respectively, in position ''. The helmet is generally symmetrical with a vertical plane enclosure between the sides, and also has a cutout and an opening. The inhalation mask that can be used with this helmet includes a mask that can comfortably engage the face of the wearer of the helmet through a face cutout, a hook that can be attached to the mask on each side, and hooks that can be attached to the mask, and hooks that can be attached to the mask to connect the mask to the helmet. A spring is connected between the hook and the mask to pull it toward the mask.

Setting the appropriate mask anchors at the same locations as the straps are attached. Make sure it is placed firmly. , this mask is therefore quite compatible and quite satisfactory, since the network of straps in the helmet transmits the force over a large area.

According to another feature of the invention, the anchoring element is integral with each side of the shell. These are also provided with fittings that secure the anchors to each side of the shell.

Each hook according to the invention comprises a front part that can be pivoted onto the mask, a Mi+ side part and a telescopic rear part.

The spring means is a spring connected between these front and rear parts. A hook part supported on the lateral part can engage the rear of the respective anchor element. Each latch hair is further
Latch means are provided for holding the front and rear portions apart against the force of the spring means except when the respective hook portions are engaged over the respective anchor pieces. The hook portion and the front portion support respective interlocking latching structures constituting the latching means, and the hook portion supports one position of the structure for interlocking and preventing relative displacement of both portions. and the other position of #4 structure that does not touch each other. Further, in each hook, one of the respective front portions and the hook portion is formed with a series of serrated teeth capable of engaging the structure of the other of the respective front portion and the hook portion; At the other position, they are separated from each other to prevent the movement of force between them. The hook rests on the part of the mask, so when it is not used, the helmet does not have to have any unnecessary configurations.

With this device, it is therefore possible to apply the stripe cloth very quickly. The user first pulls the arms by pulling out each rear section and hook section in their mating grooves. Next, the mask is placed on the face of the wearer X1, and the arm section is moved so that the latch structure is removed and the hook section is received by the anchor. t/I+ is applied. When properly installed,
The serrated teeth prevent undesired separation of the telescoping front and rear sections, so that only a user or other person skilled in operating the assembly can remove the mask.

Each hook according to the VC of the invention is provided with a visible but non-extendable element which is connected between the side part and the rear part respectively and which does not allow movement such that they are mutually l'il. In this way, an accidental separation of the rear part from the 1jJ side of each arm is not possible.

The helmet according to the invention further comprises an annular strip connected to the radial strip and located in a generally horizontal plane perpendicular to the plane of symmetry; A longitudinal strip having ends f1 is drawn. The helmet may include a front cushioning member disposed inside the shell above the facial cutout, which member is generally bisected by a plane of symmetry and capable of engaging the forehead of the helmet.

In this way, the entire shell can be precisely placed on the wearer's head.

The shell according to the invention is double-walled, and the helmet further comprises a translucent lens, which is located between the lower part of the upper part of the facial incision and the wall of the shell. The shell is pivoted between a raised position located above the notch. The helmet further includes a transparent face overshield, which extends between a lowered position on the overall face cutout and a raised position located on the face cutout between the walls of the shell. Rotated by the body.

An eye shield is formed on this cover that projects in 113 directions from above the face cutout in the raised position of the ri cover.

In the lowered position, the sunshade constitutes a neck protector.

The above-mentioned and other features and objects will become more apparent from the following description taken in conjunction with the accompanying drawings.

1st. As shown in Figures 3 and 5, the rigid synthetic resin helmet shell has a strip assembly mounted therein, which is generally a standard inhalation mask having a lens element. Can be used with 3.

The shell l forms a facial notch /a located at the top of the wearer's face F and a neck notch l) through which the wearer's neck N passes. It is symmetrical around a vertical plane of symmetry P (Figure 3) and has a pair of side parts 1C (Figures 3 and 3) that go over the ears of the orthodontist.

The strip assembly comprises an outer annular strip 5 bisected by a plane of symmetry and inclined upwardly and forwardly and lying generally in a plane towards the facial notch/a. The current strip is fixed to the shell l at six equally spaced points by rivets,
Also, attach the clip 7 at the middle part of O to these rivet installation positions.
The inner annular band (gVC) is then secured, and this band engages around the wearer's head like a headband. One of the clips 7 is configured like an adjustable buckle, like a hard hat or the like, allowing the length of the strip 5 to be varied to suit different dimensions of the head.

The upper strap assembly includes forward, central and rear radial straps 9 extending downwardly from a common directional strap. With lO and /I, ta, the direction strip is located in a plane P towards a point l, which is located at the wearer's ear. The pattern direction strip l- is a clip or buckle 1 for adjusting its length.
3 on the shoulders, and the obi strips, IQ and l/ are each buckled lS.

16 and/or, these buckles are also adjustable and riveted to the respective side /C of the shell offset from the MIJ position ig. In this way, earphones or listening holes can be installed at these locations on the ff-tag. The tether strip/g extends downwardly from the center of the rear strip 1/ to the rear center of the shell l to facilitate donning and removal of the helmet. A chin strap iq with an end extending towards point /g and attached near position 1g by an adjustable clip or buckle passes under the wearer's chin.

It is thus possible to adjust the straps 10 to set the vertical position 1 of the shell 1 on the wearer's head. Adjustment of the strip 10 and /l can adjust its front versus rear position. If adjusted appropriately for a 1 degree wearer,
The helmet will be easy to put on and take off, will be placed in the same position on the wearer's head each time, and will be attached tightly enough that the helmet will not be easily shaken off.

It is also possible to fasten all strips q, io, ii and lq to a single buckle disk, as shown in Fig. It has self-tightening slots θ and 11 and another arcuate slot 3 for the strip lq.

The third mask is held in place on the face F by one and the same hook element or arm-5, which is shown in more detail in FIG. An integral anchor may be engaged onto the bare cog. Each armco SVi has a sturdy mounting section, which is fixed in turn at its front end to a sturdy frame body surrounding the lens holder, and is pivoted around two vertical axles 30. The arm part 1-5K has a tubular Ail side part-g in which the bin 30 is provided, and a rear part surrounded by it, which is telescopic and supports a vertically pivoting bin 3.2 for the hook part 3/. 9 is formed. A tension spring 33 is engaged at its front end to the pivot pin 30 and at its rear end to the pin 3, and partially pulls 2g and 29 towards each other, and is also flexible but capable of extension. A cable, /lI, is also connected between these bins 30 and 3 to prevent the bins from being too far apart from each other.

The front part -g has teeth 3S on the outer side of its rear end, and can engage with the M surface of the prong 3S formed on the inner surface of the outer part 37 of the tri7 hook part 31. The hook J/ is thus pulled back away from the mask 3, as shown in FIG. n') holding the parts in a so-called cocked position;

Mask 3'Ir on a helmet: To put on the mask 3'Ir, it can be secured in place by hand, and the user first pulls the hook arms 2S to the cocked position υ, and then puts the mask 3 on his/her face. The flexible scar of the mask 3) d forms an airtight seal. As shown in Figure S and Figure 6, the arms 2S are then pivoted around the shaft 30 as indicated by the arrow ag until they reach the position shown in Figure 6. The front inner end 3 of the hook part 31 holds the anchor 2 at the front side i.
c, and the hook portion 31f rotates around the shaft 3 as shown by the arrow 0.

This action releases the teeth 35 and 36 from each other and causes the member and the hook portion 31 to move in the direction of the arrow D/ until the hook portion 31 engages the anchor member as shown in FIG. As shown, it is snapped forward under the force of spring 33.

The outer surface of each front part, 2g, is formed with a single serrated tooth bar with a vertical flank facing forward, and the inner part 3 of the hook part is formed with an opposite one that can be engaged with an 11-tooth dowel. Knurled teeth t3 are formed to lock the two elements together so that they do not come apart.

Mask 3 is attached to each hook J/to disengage the octopus and Da 3.
It is removed by pulling out the front part of the anchor, which causes the shifter 31 to be pulled back from the anchor rod. In this way, the mask 3 will not be torn apart if accidentally knocked down, and in fact can be easily removed by a person familiar with its operation.

A tubular foam seal is provided around the face opening/a of the shell, which engages the frame 27 of the mask 3 and provides wrinkle protection for the wearer. Provides a barrier to deception. Once the helmet is properly adjusted, the mask fits perfectly and is readily available to the wearer.

It is similar to the equipment shown in Figures S and M9, and the same reference numerals have functionally identical constructions.
refer. The arm 5 now extends at an angle and the anchor rod is fixed in place by a fastener. The upper strips q to // are integrated into a single piece and fixed in position 1g by means of rivets.

The shell/ is provided with a part of the shock absorber S on the wearer's forehead, so that the wearer's face F always has a predetermined sweep at the rear of the facial opening, regardless of the head size I/c. Make something into reality. This facilitates the attachment of the facial mask 23.

The upper shell 1 has a single wall at least in the front part, an inner wall 5θ defining a pocket, and an outer wall 5θ,
In addition, inner lenses and outer shields are provided. The lens diaphragm 7 is tinted for sun protection and can be pivoted from the illustrated upper position t't to a lowered position in front of the upper position of the face 10/a. The Kug is located at Ail of lens width 7, is transparent, and has a substantially large lens width. A blinding plate 51 is formed at the end of it1, and this protects the throat of the person wearing the light at the lowered position -1 (not shown). The shielding lens 7 and the overshielding lens g are made of durable synthetic resin and can be used together or separately depending on whether the mask 3 is used. These are stored safely and out of the way inside the helmet shell when not in use.

The helmet assembly according to the present invention can be adjusted to fit a wide range of sizes and allows even the largest or smallest head wearers to be equipped with a helmet or air supply mask at the same time. The mask is quickly and easily secured to a helmet while maintaining a good seal with the wearer's face.
