2 Claims, 4 Drawing Figures 1 EASILY ADJUSTABLE PROTECTIVE HEAD GEAR This invention is in the field of protective wearing apparel and is particularly directed to the field of protective helmets such as helmets of the type worn by participants in sporting or other events in which head protection is desirable.
Even more specifically, the subject invention is directed to a new and improved easy to use protective helmet that is quickly adjustable while on the head of the wearer without any loss or impairment of the protective efficiency of the helmet.
Numerous items of protective headwear have been designed in the past for use by participants in athletic events. Such devices are exemplified by batting helmets worn by baseball players and the well-known football helmets worn by participants in that sport. The nonuniformity of the human head size has required that athletic teams such as baseball teams either maintain a large stock of various sizes of batting helmets or to employ helmets having size adjustment capability. Unfortunately, both alternatives are susceptible to inherent drawbacks; for example, the maintenance of a supply of various sizes of helmets is an expensive proposition for obvious reasons. The drawbacks of employing a large number of different sizes of helmets for a particular team have resulted in the use of a number of various helmet designs in which the helmet size is adjustable. Unfortunately, prior known adjustable helmets have also suffered from a number of deficiencies. For example, the prior known adjustable designs have frequently been difficult to adjust and have usually required a time-consuming removal of the helmet from the wearer's head in order to effect such adjustment by a trial and error process. In other words, the user adjusts the helmet, then tries it on and readjusts, tries it on again, etc., until a desirable fit is achieved. This operation is time consuming and is particularly undesirable in athletic contests in which there may be a limited amount of time available for effecting such adjustment. It is, therefore, highly desirable that any helmet employed in athletic events he adjustable while on the head of the user in order to cjuickly and efficiently obtain a rapid and accurate adjustment of helmet size.
While there are a number of protective headwear devices which can be adjusted while on the head of the wearer, such devices universally employ external means protruding from the helmet in a manner which would be capable of inflicting injury to persons other than the wearer and which, due to their external exposed position, are frequently susceptible to structural damage when struck by a bat, ball or similar item.
Therefore, it is the primary object of this invention to provide a new and improved article of protective headwear that is adjustable in size while on the head of the wearer, economical to produce, reliable and troublefree and does not impose any hazards on the user 'or others in the vicinity of the user.
Obtainment of the objects of this invention is enabled by the preferred embodiment through the provision of a protective shell formed of plastic and dimensioned to be received over the head of a wearer. A headband is respect to the helmet is permitted. The metal band is provided with forwardly extending adjustment tabs adjacent each end with the ends of the band being positioned in spaced relatively close facing relationship with respect to each other in the front or forward portion of the helmet with the adjustment tabs extending forwardly of the forward edge of the band. The adjustment tabs are respectively received on threaded rod members extending from each side of a knurled adjustment knob positioned on the interior of the helmet in a forwardly extending protrusion.
An access opening is provided forwardly of the knurled adjustment knob so that the knob can be rotated by the wearer while the helmet is being worn. Cushioning means in the form of a strip of foam rubber is provided on the inner surface of the headband with supporting tabs of foam rubber extending upwardly for adhesive engagement with the interior of the helmet shell for providing additional support for the headband.
.Additionally, a crown cushion of foam rubber is mounted in the top central portion of the shell. In a second embodiment, the knurled adjusting knob is mounted in a separate metal enclosure provided forwardly of the plastic shell and affixed to the plastic shell by rivets or other retaining means. Helmets of the lastmentioned type would normally be constructed from old helmets and would be for the purpose of making such helmets adjustable while on the head of the wearer. In both embodiments, the knurled adjusting knob is positioned on the interior of the helmet body per se and it is therefore not susceptible to external damage nor is it capable of causing damage or injury to other persons or items which might happen to engage the helmet in a forceful manner.
A better understanding of the manner in which the objects of this invention are achieved will be enabled when the following detailed description is read in conjunction with the appended drawings in which:
FIG. 1 is a perspective view looking upward from below the first embodiment of the invention;
FIG. 2 is a sectional view taken along lines 2-2 of FIG. 1;
FIG. 3 is a sectional view taken along lines 33 of FIG. 2; and I FIG. 4 is a sectional view of the adjusting means as employed in a second embodiment.
The preferred embodiment of the invention illustrated in FIGS. l3 comprises a protective shell 19 hav-- ing a main portion 20 formed of tough impact resistant plastic material. Rivets 22 and 24 are mounted on opposite sides of the shell and extend inwardly for providing relatively loose support for a headband 26 formed of a strip of flexible steel or the like and having plural guide surfaces defined by the peripheries of slots 28 formed in headband 26 and through which the rivets extend for providing side support for the band. The
Cushioning is provided on the interior of shell 20 by means of a headband cushion means 50 engaging the interior of the headband 26 and extending about the internal periphery thereof. A rear tab 54 of cushioned foam rubber material extends unitarily up from the headband cushion as shown in FIG. 2 and is adhesively secured to the inner surface of the shell 20. A forward tab 56 extends upwardly unitarily from the cushion 50 and is adhesively secured to the forwardmost portion of the inner surface of the shell main portion 20 so that the cushions 54 and 56 serve to provide additional support for the headband due to the fact that they frictionally engage the inner surface of the headband. In addition, the cushion memberSO can be adhesively secured to the headband if desired. Additional cushioning is provided by a crown cushion 72 positioned centrally on the interior of the main portion 20 as best shown in FIGS. 2 and 3.
Knurled adjusting knob 40 in conjunction with threaded shaft portions 38, 42 and tabs 34, 36, serves to adjust the headband to vary the size thereof. It is to be noted that the knurled adjusting knob 40 is mounted in a forwardly extending protrusion 60 of the shell main portion 20 which completelyv encloses the headband adjusting means. However, an access opening 70 permits the wearer of the helmet to manually engage knob 40 to rotate same while the helmet is on the wearers head.
Attention is now invited to FIG. 4 which illustrates a second embodiment of the invention in which the ad- 7 justing means for the headband is positioned in a separate metal enclosure 60' connected to a shell main portion 20' of high impact plasticor the like by means of rivets 62 as shown. In all other respects, the FIG. 4 embodiment is identical to the first embodiment illustrated in FIGS. 1-3. It is to be understood that the embodiment of FIG. 4 is of particular use in providing an adjustable helmet through the modification of an older style helmet shell.
It should be understood that the subject invention is not limited to a batting helmet and is capable of employment in a wide variety of helmets such as industrial headwear, football helmets, pilot's helmets, etc. Moreover, the subject invention is not limited to the exact construction shown and the spirit and scope of the invention is to be limited solely in light of the appended claims.
