1. Field of the Invention
This invention relates generally to protective helmets and more particularly, to a low profile helmet that incorporates safety design for miners.
2. Brief Description of Prior Art
The use of safety helmets (hard hats) in hazardous areas in industry and mines is widespread. Prior art helmets are generally heavy and because the shell of the helmet is spaces an appreciable distance from the wearer's head, they are often unstable on the head. In addition, the bulk of these helmets seriously limit head movement by the wearer in the often confined space within the mine.
As will be seen from the subsequent description, the preferred embodiments of the present invention overcome disadvantages of the prior art.
The present invention is a low profile helmet suitable for use in hazardous areas in industry and mines. The invention comprises a helmet embodying a rigid shell that is best described as being made up of integral portions joined together to permit the helmet to be fitted closely to the top of the wearer's head. The close fit of the helmet minimizes the weight of the helmet itself, and provides excellent stability of the helmet on the head. Because of its close fit, low profile fitting with the wearer's head, the helmet of the present invention further includes integral shock absorbing means in order to protect the head of the wearer.
The low profile protective helmet of the present invention is primarily directed to a close fit helmet that minimizes the weight of the helmet itself, and provides excellent stability of the helmet on the head. In the broadest context, the low profile protective helmet of the present invention consists of components configured and correlated with respect to each other so as to attain the desired objective.
The basic idea of the present invention is to provide a low profile helmet suitable for use in hazardous areas in industry and mines and that embodies a low profile, close fit in order to both minimize the weight of the helmet itself, and to provide excellent stability of the helmet on the wearer's head.
Referring to
As is the case with prior art protective helmets, the current invention may include various attachments such as a mounted lamp, protective visor, ear pads, as well as shock absorbing internal padding disposed within the helmet 10 for both protection and comfort. Again these attachments are known in the art and therefore not apart of the present inventive disclosure.
As illustrated, the outer shell 11 having generally spherical contours to encompass the upper part of the wearer's head. The shell 11 is preferably made of a dense, relatively light weight, impact absorbing material such as for example, a polycarbonate plastic.
The outer shell 11 is integrally formed by three sections, a center principal section 15, a front section 17 and a rear section 19. The center section 15 covers the central portion of the top of the wearer's head from a point above the ear on one side of the head to a point above the ear on the other side of the head. The front section 17 is integral to the center section 15 and covers the upper frontal portion of the head. The rear section 19 is likewise integral to the center section 15 and covers the back of the head. The sides of all three sections are configured to closely fit the head of the wearer in order to better maintain firm contact with the area of the head while the helmet is being worn.
The outer shell 11 includes an interior surface 20 that is immediately adjacent the top of the wearer's head while the helmet is being worn. The interior surface 20 includes a distal point (not shown) which represents the furthest distance between the top of the wearer's head and the interior surface 20 when the helmet 10 is being worn. The distal point of the low profile helmet 10 is approximately 1.3 inches from the top of the wearer's head which is at least one (1) inch closer to the top of the wearer's head than with prior art hard hats. In particular, the height of the low profile helmet 10 is approximately 4.7 inches in height which is considerably less than prior art hard hats. As a result, the design permits the helmet 10 to fit closer to the top of the wearer's head. The close fit of the helmet 10 minimizes the weight of the helmet itself, and provides excellent stability of the helmet on the head.
As best shown in
As illustrated, the first extension 27 horizontally extends along the central portion of the center section 15. The second extension 29 is disposed in perpendicular relationship to the first extension 27. The second extension 29 vertically extends along the central portion of the center section 15 and extends such that a first end 29A is approximately adjacent the front section 17 and a second end 29B is approximately adjacent the rear section 19. As stated, the extensions 27, 29 forming the added shock absorbing means 25 give added protection to the head of the wearer during use.
As shown in the drawings, the shell 11 further includes a pair of slots 35 for attaching hearing protection pads known in the art and further includes side channels 37 for attaching internal suspension padding known in the art.
The inventor has found that the design of the protective helmet 10 as described represents the only ANSI Z89.1 Type I Class G certified hard hat having the “low profile” characteristics described.
While the best mode for carrying out the invention has been described, those familiar with the art to which this invention relates will recognize various alternative designs and embodiments for practicing the invention. Thus, the above-described preferred embodiment is intended to be illustrative of the invention which may be modified within the scope of the appended claims.
