Description

PROTECTIVE HEADGEAR WITH VENTILATION

FIELD OF THE INVENTION

Generally the present invention relates to protective headgears. In particular, the present invention pertains to protective headgears with ventilation.

BACKGROUND

Today, there exists a wide range of protective headgears. Often these protective headgears are used in environments Or tasks that cause stress and require physical activity.

Further, during these tasks workers are often equipped with other equipment such as safety garments and tools or machinery. Such equipment may prevent heat from exiting the body and may require the worker to carry an extra load. Safety garments may include overalls that cover most of the human body. Tools and machinery may be arranged around the waist or may be carried by the worker, for example.

The additional equipment required on worksites may increase the stress levels on the human body and even more heat will need to exit the body than in normal conditions. The human body may start sweating when it is exposed to heat or physical stress. Sweating is often uncomfortable and it may affect the worker's performance on a worksite. The risk for mistakes may increase when workers are affected by sweating and stress.

Sweating and stress may decrease if the body is cooled. One way to cool the human body is to design protective gears that ventilate the body. Ventilating materials and ventilation holes are proven to facilitate air flow so that cooling may be applied to the human body. However, with protective headgears it has been a challenge to create a design that ventilates enough and provides sufficient protec- 3 5 tion for the working environments.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Referring to figures 1-9, the protective headgear 100 comprises a protective shell 102. The protective shell 102 comprises four inlets 104a-d arranged in the front section 106 of the protective shell 102 and eight outlets 108a-d, 110a-d arranged in the rear section 112 of the protective shell 102. The front half of the protective shell 102 may be considered as the front section 106, and respectively the rear half of the protective shell 102 may be considered as the rear section 112 of the protective shell 102.

The inlets 104a-d may be arranged substantially at the same height in line so that they cover a significant portion of the width of the protective shell 102. Thus, air may enter in the front of the headgear across the width of the inlets 104a-d.

The outlets 108a-d, 110a-d may be arranged successively in two lines 114, 116 in the rear section 112 The first line may comprise four outlets 108a-d arranged successively in line. The second line may comprise four outlets 110a-d arranged successively in line.

The first and second line of outlets 114, 116 may be arranged respectively on a first and second side 118, 120 of the protective shell 102. The first and second lines of outlets 114, 116 may be arranged so that one outlet in each line is arranged substantially at the same height. The first and second lines of outlets 114, 116 may be arranged at a distance from each other.

Sections of ventilation holes 122a-d, I24a-d may be arranged to the first and sec-ond side 118, 120 of the protective shell 102. Four sections of ventilation holes 122a-d may be arranged to the first side 118 of the protective shell 102, and respectively four sections 124a-d of ventilation holes may be arranged to the second side 120 of the protective shell 102.

A first and second front cut 130, 132 may be arranged to the front section 106 of the protective shell 102. A first and second rear cut 134, 136 may be arranged to the rear section 112 of the protective shell 102. The first and second front cuts 130, 132 may enable the expansion and contraction of at least part of the front section, and respectively the first and second rear cuts 134, 136 may enable the expansion and contraction of at least part of the rear section 112.

The protective shell 102 may be made of high-density polyethylene (HDPE) plastic, polycarbonate, polyamide (e.g. Nylon 6), polyoxymethylene (POM) or acrylonitrile butadiene styrene (ABS), for example.

Referring also to figures 10-22, the protective headgear 100 comprises a protective shell 102 and an insert 140.

The protective shell 102 may comprise attachment means such as two front attachment holes 142, 144 and one rear attachment hole 146 for attaching the insert 140 to the protective shell 102.

Respectively, the insert 140 may comprise attachment means such as two front protrusions 148, 150 and one rear protrusion 152 for attaching the insert 140 in the two front attachment holes 142, 144 and one rear attachment hole 146 of the protective shell 102. The front and rear protrusions 148, 150, 152 may be fitted so that the protrusions attach with the front and rear attachment holes 142, 144, 146 of the protective shell 102. Thus, the insert 140 may be attached on the inside of the protective shell 102.

The insert 140 comprises four channels I54a-d to guide air from the inlets 104a-d of the protective shell 102 to the outlets 108a-d of the protective shell 102. The channels 154a-d may be arranged so that the channels align with the inlets 104a-d of the protective shell 102. Each channel 154a-d connects with one inlet 104a-d. Further, the channels 154a-d may be arranged so that two channels 154a, 154b connect with a first outlet 158a of the insert 140. Similarly, two further channels I54c, I 54d may connect with a second outlet I56a of the insert 140.

The channels 154a-d form a passage between the insert 140 and the protective shell 102 for air flow. The channels 154a-d may be arranged as grooves in the insert 140.

The insert 140 comprises eight outlets 156a-d, 158a-d. The outlets 156a-d, 158a-d of the insert 140 may be arranged so that the outlets of the insert align with the outlets 108a-d, 110a-d of the protective shell 102. The outlets 156a-d, 158a-d of the insert 140 may be arranged successively in two lines 160, 162. The first line 160 may comprise four outlets 156a-d arranged successively in line. The second 162 line may comprise four outlets 158a-d arranged successively in line.

Additionally, the channels 154a-d may comprise holes 164a-h to provide further ventilation in the protective headgear.

The insert 140 may be made of polypropylene foam, polystyrene foam or polyurethane foam, for example.

The protective shell 102 may have a height of approximately 119 5mm, a width of approximately 168.8mm, and a length of approximately 206.2mm. Referring to figure 8, the protective shell 102 may have a thickness of approximately 2mm The thickness may vary in different parts of the protective shell 102. In some parts of the protective shell 102 the thickness may be 1.14mm, 1 2mm or 1.5mm, for example.

The insert 140 may have a height of approximately 99.1mm, a width of approximately 126.6.mm, and a length of approximately 207.8mm Referring to figure 22, the insert 140 may have a thickness of approximately 9.2mm. The thickness may vary in different parts of the insert 140.

Referring to figure, 12, the insert 140 and the protective shell 102 may form a 5 thickness of approximately 11.5mm when attached together. The thickness may vary in different parts of the protective headgear 100.

Consequently, a skilled person may on the basis of this disclosure and general knowledge apply the provided teachings in order to implement the scope of the 10 present invention as defined by the appended claims in each particular use case with necessary modifications, deletions, and additions.
