Abstract

In this publication is described a traditional forest helmet visor (1), plus in accordance with the invention a lightweight and ventilated plastic frame- body (3) that is connected to downparts of the visor (1) and a fabric- curtain (2) fastened into the inner circle of the framebody (3). The true function of the framebody (3) is to position a lightweight and elastic fabric-curtain (2) to an optimal location near the upper part of neck. For setting work mode the backsides of the framebody (3) can be connected either to the hearing protector structure or those can be connected together by expresshooks being in each other's endparts. Whith these solutions the fabric-curtain (2) can be positioned as aimed broadly round the circle of the upper neck. As a result the fabric-curtain (2) is properly interlaced and efficiently supplyes protection for the bare nec and face areas together with the current workwear. Due to the protection a general mobility in brushwoods is getting simpler and that equally enables a rise in working performance. The improved mobility is quite an advantage specially in clearingsaw-work, because it as a workform requires more motion just among branches. In addition the hearing protectors can be equipped with quite a familiar fabric-curtains and hangers as well. In the combimodell the backsides of the framebody (3) can be sized significantly shorter (21) accordingly and there is no purpose for any fastening elemets for work mode.

Description

Protective visor for a forest helmet

This invention is constructed from a forest helmet visor and a protective framebody positioned in the down- and backedge parts of visor and a fabric stripe fastened into inner circle of this framebody. A sort of protective fabric-body structure can be utilized solely in visor or optionally both in hearing protectors and in visor.

Traditional provisors are sized vertically downwards with maximum to extend the the peak of chin area to enable free mobility of head into down and downside directions. This compromiseform caused by the rigid base structure lets treesticks and branches quite a free way into nec and downface areas, escpecially with normal and upangled working positions of the helmet.

Some obvious cure to this limitation has sofar supplyed by high and tight collars and more rarely hood and commando headdresses , with their lower hems clearly interlacing with high collar wearings.

The aim of this invention Is, with reform of necprotection provided by helmet visor, to minimize especially in clearingwork the caring caused by the tendense of branches and twigs to come in contact with nec, chin and downface areas and and by the same minimize the lost of working performance caused by this extra observation.

Moreover aim is to reduce the need for wearingprotection in areas around nec and face. As known in high temperatures air is the most comfortable element to contact skin, this rules specially in nec and face.

Collars, jacketcollars and sweat combined with mobility are exposing skin in nec area to abrasions. At the same time tight collarwearings reduce the local coolingeffect of perspiration. The additional aim with invention is up to boost comfort right while hot weathear conditions. Moreover the construction can act as a wearing and supply protection for necbody areas agains cold and wind.

Protective fabric-curtain, with qualities thin and light, prevents sliding twigs to contact with skin and effectivly obstucts twigs and branches to intrude inside the visor. And you can not get this kind of protection with any hoodwear.

Due tot the lightness properties of protective framebody and fabric. The extraconstruction is almost unnoticed to utilize. This is as well consequence of the upcoming small friction between the curtainfabric and the upperbody wear.

Aim is to get the framebody as ventilated as possible, that is reached by using extensivly for example vinylnet. The aim with proper ventilation is to compensate that partial warmingeffect caused by the fabric element.

Construction do not appreciably strain the basic visor and visor's fastening and joint structures. This factor is contributed by the aimed lightweight and slippery qualities of the structure, by the utilization of fabric element and by the usage of hearing protectors as a support point to extra framebody. Normal loose sized extra framebody do not prevent the employment of a full-scaled waistwear at once.

Next the invention is discribed more profaundly quided with the enclosed pictures, in which

Figure 1 demonstrates the framebody and fabric-curtain attached to traditional visormodell as seen from the sidedirection,

Figure 2 demostrates the framebody as seen from above,

Figure 3 demonstrates the curtainhanger attached to hearing protector,

The form and sizing of the framebody 3 (Fig. 1 and 2) enables that the fastening ring 10 (Fig. 2) is positioned quite near to upper necring area, in consequence, that the fastenable polyester fabric-curtain 2 (Fig. 1) is able to interlace properly with even a shorter collar , and thus resulting a working protection and comfort.

The construction is simplest one when it is attached only into visor (Fig. 1 and 2). To get a proper protection the framebody 3 (Fig. 1) has to extend with backsides 8 (Fig. 2) as behind to backnec area as possible.

Backsides 8 can be sized as long that they can be connected with express hooks 23 and 24 to each others's end. In that case there is no need to fastening elements in hearing protectors 20 (Fig. 3) with their counter elements 19 (Fig. 2) in backsides 8.

The working challenge caused by the size of backsides is to be solved with shaping the backsides to be positioned right open in base form (Fig. 2). This enables the normal functions of the visor; lifting up and laying down to working position. Moreover open sructure gives a better field of vision from sides when visor 1 (Fig. l) is being uplifted and and with fabric-curtain 2 (Fig. 1) being lifted as well upon framebody 3 and visor 1 (Fig. 1).

There is as a fastening elemet studs 19 (Fig. 2) both in backsides 8 and counterstuds 20 in hearing protectors 4 (Fig. 3).

The extra extended backsides 25 and 26 with the endpart fastening elements 23 and 24 are demonstrated by the dotted line in (Fig.2).

Movement to working mode is made by attaching backsides 8 with bending them 18 (Fig. 2) into the fastening elememts 20 of downlaid workingmode hearing protectors 4 (Fig. 3). Likewisely you have to unlock backsides 8 from hearing protectors before uplifting the visor.

In case with extended backsides 25 and 26 (Fig . 2) fastening is easily made by connecting the fasteningparts 23 and 24 ; Resulting a complete circleframe around the head.

The fabric-curtain 2 (Fig .l) is narrowing down the field of vision when visor is in uplifted mode. For that reason it can be equipped with studs 9 (Fig. 1) with counter studs in a frame body 16 (Fig. 1). So you can lock the uplifted curtain with these fastening elements. If necessary the sliding down of uplifted fabric-curtain 2 (Fig.l) can be prevented by other simple ways as well. Those can be based on friction elemets or sizing of the fabric-curtain 2. S

There can be familiar protective curtainhangers 5 with fabricstripes 6 also in hearing protectors 4 (Fig. 3) . Curtainhangers 5 can consist of flexible material at least in bottoms with partial vinylnet in body. For working protection effect the curtainhangers 5 must extend distinctlvly forward with front ends to be able to interlace properly inward with the backedge 21 (Fig. 1) of the utilized framebody 3.

The combimodel visor is normally utilized with the exeption that the hearing protector structures (Fig. 3) are laid down before the fall of visor 1 (Fig. 1) to get the aimed interlacing.

The framebody 3 (Fig. 1) can be manufactured either as a united part of visor 1 or it can be a fixable one, designed to be attached with integrated visorstructures and corresponding structures 11 (Fig. 2) in the upper part of framebody 3.

The fabric-curtain 2 (Fig. 1} can be a replaceable one, designed to be locked with studs into the framebody counterstuds 15 (Fig. 2).

Moreover the fabric-curtain 2 can be made attacable by fastening studs 14 to be connectable with integrated counterstuds positioned in upperbody wearings or in harness.

The framebody 3 (Fig. 1) is build up of nylonnet 27 (Fig. 2) strenght - ened by plastic body or stripes. The aimed functionality of a visor 1, framebody 3 and fabric-curtain 2 is better when treebranches and sticks glide with smaller friction in contact situations. This at the same is reducing the presssure against the visor 1 and it's structures.

The framebody 3 (Fig. 1) is possible to size looser inwards when the fabric-curtain 2 is equipped with a specific ribbing texture 22 or with another tightening or adjusment mechanism.

What above is discribed is only one guideline to realize the basic idea of this invetion. In addition the invention can vary essentially within protection claims in particular referring to materials utilized and allover sizing.

The framebody 3 and fabric-curtain 2 (Fig. 1) do not necessarily demand any structural intensification concerning the visor 1, net- texture 12, netframe l3 or joints 17 utilized in existing solutions.

The invention improves and simplifies mobility in thickets and equally makes easier to work closer to trees. At the same, these performance factors bring to light the utilized visor's 1 (Fig. 1) sliding and endurance qualities. Regarding abovementioned aspects, nylon-netvisor is more withstanding to respond the challenges extra speeding brings along.
