DE4426470A1 - Breathing appts. with air filter, esp. for cyclists - Google Patents

Abstract

It has a filter (2), an outlet (5) and an inlet, and can be used for breathing via the mouth (4), and if necessary also via the nose. The filter and a connection (3) which leads to a mouthpiece (10), are separated three-dimensionally from the air inlet and outlet sections, and are arranged near the head, e.g. on a helmet (9). A valve which automatically opens on exhalation is fitted to the mouthpiece, and the connection leading from the filter is arranged between the mouth inlet and the valve.

Description

The invention relates to a breathing air device with a Air filter and an inlet and an outlet for to be breathed through the mouth and possibly also through the nose Air, especially for cyclists and two-wheelers and in air-contaminated traffic areas.

Known breathing air devices for this and further purposes are usually subject to the Humidification that switches off the filter effect exhaled air or are too expensive or complicated as well as too unwieldy.

The object of the invention is to create a optimally light, easy to handle, d. H. at the Use non-distracting or unobstructed view influencing breathing air device, even in the simplest Can be put together from individual parts and can consist of cheap tool parts.

Accordingly, the invention consists of a Air filter of the aforementioned type, in which the air filter and his breathing air connection leading to the mouth Air inlet and outlet sections spatially are provided separately that the Air filter near the head, e.g. B. at the Headgear (helmet) is arranged that the  Breathing air connection on your facing away from the air filter mouth end is provided with a mouthpiece, which automatically exhales when exhaling Has outside air opening valve, wherein the mouth end of the breathing air connection to the air filter is arranged between the valve and the mouth inlet.

It is particularly important that this air filter moves with every head movement that be Air filter large volume and easy to replace and that it can be attached to bicycle and motorcycle helmets is, the filter is also fall-absorbing is.

Otherwise, the breathing mask according to the invention is for any other purpose that will become necessary in the future (e.g. Walking) can be used.

The fabric wall is as flexible and deformable on outer contours (e.g. on the outside of the helmet) Define filter material, but also from tissue can consist of perforated foils whose air-permeable pores also areas can have different air permeability, in order to achieve a flow as uniform as possible Filter material from the inflowing through the filter Air with the least possible air resistance guarantee.

The fibers of the filter material can also hold granular filter-active material between them, where its grain size and the layer density of the fibers of the filter material functionally on the hold of the granular material are matched.  

Also those that possibly reach into the air filter Filter-side end pieces of the breathing air tubes can additionally be provided with holes to a even flow through the filter material favor.

The invention also consists in the features and Combinations of features that, except in the description, are also defined in claims 2 to 10.

In the two-wheel helmet 9 shown in perspective in Fig. 1, an air filter 2 z. B. by means of interlocking profiles 17 or Velcro fasteners 18 (see. Fig. 3 with both alternatives) easily removable attached to the upper or rear part of a helmet 9 . The air filter 2 has a somewhat deformable, breathable fabric cover or wall 15 and is puffed up or inflated with a breathable material 16 , for. B. fibers or granular filter material held in between, which are coated with absorbent material for harmful gases, coated or flocked. The still large volume and densely fluffy filter material with low air resistance also holds z. B. dust and soot particles back, which is particularly favored by the comparably large volume.

With a comparatively voluminous formation of the Filters also reduce the impact.

The air filter 2 is provided on the side of the helmet 9 with hoses as a breathing air connection, which can be simply plugged into the air filter 2 by means of plug connections 21 .

Referring to FIG. 3 of the filter is a curved (or bendable) tubular piece inserted 24 (not shown) in a seam line in the upper half, which protrudes with a plurality of passages 25 in the volume of the air filter and this can also stiffen.

The breathing air connections 3 can be provided on both sides (or on one side) - cf. Fig. 1 and 3 - and flow, even in such a mouthpiece 10, which may simply hang down when not in use on the neck. B. in the presence of a quick connector in two parts, the breathing air connections 3 are guided outside the helmet straps 27 .

According to FIG. 4, a nose cover 22 upstanding from the mouthpiece 10 via the nose.

The longitudinal section of the mouthpiece 10 in FIG. 5 is pushed into the mouth with its retaining brackets 12 between the front teeth in that it can be held in place by means of a bit profile 13 .

Inhalation and exhalation take place through mouth inlet 7 (arrow B), which takes place via automatic valve 11 for exhalation into the open air (arrow A). Inhalation takes place through the breathing air connections 3 connected to the mouthpiece, in which check valves 14 , which prevent breathing back into the air filter, can also be provided.

Since the entire breathing air device, in particular also the mouthpiece 10 , is not exposed to any high loads, all parts can be made of lightweight plastic, especially since a certain breaking effect in the event of an accident may be desired.

Magnetic, vitalizing magnet devices 19 can also be connected to the breathing air connections 3 , in which the breathing air is treated to improve performance by means of very weak magnets.

Other vitalizing devices 20 (flavoring) can also be used.

The fabric cover can be used to protect against fog impregnate the air filter accordingly.

The actual air filter 2 consists of a sack or bag-shaped or bag-shaped or bead-shaped body, which the outer contours of the body to which it is to be attached can be easily molded - as for example in FIGS . 1 and 3, around the rear Section of a bicycle helmet. The filter body can also, for. B. flexible stiffening elements, e.g. B. have chopsticks.

In order to ensure that the flow in the filter body 2 is as uniform as possible, certain areas of its breathable material wall can be prepared for reduced or increased passage (for example, more or less blocked pores).

To adjust the uniform breathing air flow, filter-free passages can also be provided in the filter body and a variable length of the breathing air connections 3 projecting into the filter with holes 25 of different sizes can be used.

It is conceivable that the filter body 2 can also be easily cleaned by yourself. In any case, they are independent, ie they can be replaced independently of other breathing apparatus.

The area exposed with the filter body 2 can also be provided with advertising markings.
