Abstract

A protective device has been explained for the protection of the head, primarily, during certain work operations in which there is created a hazardous environment, for example during sandblasting. The protective device (10) comprises a helmet section (12), which is connected to a hood (16). To cover the user's ear protection (24), the helmet section (12) has, on either side, an attachment means in the form of an attachment lug (22) for the securing of the respective ear protection (24) within a region on either side of the protective device that is covered, in the position of use, by said hood (16), which is releasably attached to the connecting portion (14) of the helmet section (12), extending along the circumference of the helmet, apart from in the region of the ear protection (24) on either side of the helmet section (12), where the connecting portion (14) of the helmet section has an extent above the respective attachment means (22). Thus, when the hood (16) has been joined to the helmet section (12) along its connecting edge portion (34), the stably mounted ear protections (24) secured to the helmet section, are protectively covered from the outside by a hood portion each.

Description

PROTECTIVE DEVICE FOR HEAD
This invention relates to a protective device, first of all for the head, comprising a helmet formed with a hard helmet shell and with a hood and mask releasably connected thereto, the helmet covering the top of the head, and extending further over the forepart of the head, where it forms a means of attachment for the mask, and below this mask the front portion of the hood, and to the back of the head where an air hose can be connected, the hood being releasably attached to the front, back and sides of the helmet, i.e. along a 360° circular line, after which the hood, covering the neck, extends at its lower terminal edge to the user ' s upper chest portion and shoulder portions.
The mask which is to ensure the user's view, comprises one or two discs of transparent glass or plastic, placed parallel to one another and spaced apart in the direction of view. The glass/plastic discs are arranged to allow replacement individually/in pairs. Such head protection devices are included in protective equipment used in sandblasting, high-pressure washing with water etc., and shall, among other things, prevent sand dust and moisture from entering the protective device.
Measurings carried out in connection with exposure to noise in noisy environments, for example during sandblasting, by a great amount exceeds the criteria for workplace noise, the expected effect of ear protection taken into account. For the personnel the exposure to noise can exceed 83 dBA.
In ultra-high-pressure washing the helmets of the known head protection devices are open round the ears, and the noise levels without ear protection, will correspond to the noise level by the user's head. The exposure to noise during ultra- high-pressure washing will clearly be higher than common criteria for risks of hearing damage. Even by the use of very good ear protections, which will provide a damping of up to 20 dBA in practice by conventional or other known positioning of the ear protections externally on the head protection equipment, exposure to noise of up to 90 dBA could be possible.
In sandblasting the glass or the transparent plastic discs of the mask are exchanged regularly due to wear. There is reason to believe that the collision of the sand particles with the external surface of the helmet contributes to increasing the noise level inside the protective device.
To reduce the noise level, to which the user is exposed, it is known to use ear protection placed on the exterior of the head protection device. To have enough space inside the head protection device, the less effective ear plugs must be used to protect the hearing.
The invention thus relates to a protective device of the kind mentioned initially, in which the aim has ,been to allow the use of superior ear protection, wherein this is mounted in position, one on either side, and is protected against external influences.
This object has been realized in that a protective device of the kind mentioned in the introductory part of Claim 1, is formed to exhibit the characteristics appearing from the characterizing part of Claim 1.
Above the ear region, which is to be covered by the damping part of the ear protection equipment in the position of use, the helmet section of a protective device for the head (head, neck, upper shoulder portions) primarily, is provided with a attachment means on either side, in the form of a downward attachment lug, for the securing of the securing element of the respective hearing protection equipment, carrying said damping element, for example by suspension arms, releasable connecting means between the helmet section and the hood below, extending round and outside said ear regions and attachment elements of the helmet section.
Thereby each piece of hearing protection equipment may be reliably mounted through securing to the hard, stable helmet shell, the ear protection being covered after being secured, with adjacent portions of the protective device, the upper connecting edge being releasably secured to the corresponding connecting edge of the helmet shell after the hood has been placed protectively over the whole ear protection equipment on either side, including the damping element, suspension arms and securing element. The connection of said connection edges can take place by corresponding, mutually adapted edge configurations, or an intermediate specially profiled connecting strip of suitable flexibility can be used.
A non-limiting example of a preferred embodiment is illustrated in the accompanying drawings, in which:
Fig. 1 shows a perspective side view of a head protection device, in which the portion of the hood, covering the ear protection equipment on either side of the protective device in the position of use, has been detached from the connecting edge of the helmet section to show the major part of the ear protection within;
Fig. 2 corresponds by and large to Fig 1, but here the connecting edges of the helmet and hood co-operating releasably with one another, are joined together, so that the ear protection on either side is covered by the hood;
Fig. 3 shows the protective device according to Fig. 2, seen in elevation;
Fig. 4 shows, on a somewhat smaller scale than Figs. 1-3, a side view of the helmet section with mask and attachment lug for the respective ear protection;
Fig. 5 shows, on a considerably larger scale than Fig. 1-4, an embodiment of a device for releasable connection between the connecting edges of the helmet and the hood. The protection device 10 is preferably formed of plastic.
The opening for a transparent portion 11 of the protective device 10 is formed in a helmet section 12 of the protective device, which comprises a helmet shell formed largely in the shape of a U, extending symmetrical, including a free connecting edge portion 14 thereof for the hood 16, Figs. 1, 4 and 5, about a vertical central plane I-I, Fig. 3, referring to the protective device 10 being oriented vertically. The protective device 10 extends over the top of the head in the longitudinal direction, over the forepart of the head with the face and over the back of the head, where the protective device 10 is connected, in a known manner, to an air supply hose 18 with a central point of connection.
The helmet shell is formed with a double curvature, and is formed with a circumferential connecting portion 14, which forms the terminal edge of the protective device 10, apart from in the areas of the downward attachment elements 22, Figs. 1 and 4, of the protective device 10, for the securing of conventional ear protection equipment 24 of superior quality.
Each ear protection 24 is secured to the attachment element of the helmet shell 12, the attachment element possibly being in the form of an attachment lug 22, by means of for example a screw/bolt 26 screwed through a hole in the attachment lug 22 and possibly secured by a nut/disc or similar fastening/ securing means on the inner side of the attachment lug 22.
Apart from the possibility of attachment, the ear protection 24 as such is not an object of the present invention, but it can be mentioned briefly that it comprises a disc-like attachment element 28 with a hole therethrough for said screw/bolt 26, and with depending, suitably bent suspension arms 30 mounted thereon, at the lower ends of which the damping part 32 of the ear protection is pivotally supported.
The protective device is provided with a hood section 16.
The hood section 16 has a connecting edge portion 34, consisting of, according to Fig. 5, an endless, flexible profiled strip, to which the upper edge portion 16a of the hood 16 is secured in a downward open, upward closed reception groove 36 in the profiled strip.
In the present description the profiled strip is considered as the connecting edge portion 34 of the hood 16, which should allow easy releasable connection to the corresponding, complementary connecting portion 14 of the helmet section 12.
The two connecting portions 14 and 34 are releasably connectable in that the elastic, flexible connecting edge portion 34 is pressed like a snap-lock by its elastically yielding, back-springing opening onto the projections 14 extending along the circumference of the helmet section, from where the connecting edge portion 34 of the hood 16 can be removed, either locally (Fig. 1) or totally (Fig. 4) through the elastic deformation of the connecting edge portion.
When ear protection on either side of the head protection device is secured through the attachment lugs 22 and attachment means 26 of the helmet, they are covered through the folding up of the locally released hood side portions, which are connected by the connecting edge portions 34 to the connecting portion of the helmet 12, after which both ear protections 24 are well protected against external influence through the securing to the helmet section and through the covering by the hood 16.
