ADJUSTABLE FACE GUARD BAR Filed Jan. 27, 1958 2 Sheets-Sheet 2 United States Patent O ADJUSTABLE FACE GUARD BAR I Theo J. Sowie, Grand Rapids, Mich. Filed Jan. 27, 1953, Ser. No. 711,266 "12 Claims. (Cl. 29)

This invention relates to athletic head gear and, in particular, to face guards mounted on athletic helmets. I-litherto, athletic helmets have been provided with horizontal U-shaped face guard bars secured at theirY 4cheek bones. Such prior helmet-attached face guard bars, however, have been inadequate by reason of the fact that the face guardor bar, when once attached, was suitable only for a particular player or for players of the same vertical facial dimensions, and unsuitable for players of other facial dimensions since the guard bar in such cases would be either too high or too low to give proper protection to the face of the other player. The drilling of additional holes in the sides of the helmet to relocate the guard bar has been unsatisfactory because of the fact` that the later-drilled holes sometimes must be so close to the previously-drilled holes as to overlap them when the guard is properly positioned for the new player after having been previously positioned for a previous player. This defect is particularly serious in athletic teams of small institutions or those of limited financial resources.

The present invention provides a helmet-attached horizontal U-shaped face guard bar device which is pivotally secured to the sides of the helmet and which has locking means adapted to lock the end portions of the guard bar against the sides of the helmet in any of a wide range of positions upward or downward. 1n this manner, the same helmet, with its guard bar attached, is quickly and easily fitted to any one of a number of players of different facial measurements yet will still give proper protection to each athlete, regardless of his facial measurement. i i

Accordingly, one object of this invention is to provide a helmet-attached horizontal U-shaped face guard bar device which is provided with means for adjusting it upward or downward tot faces of different measurements and is also provided with means for rmly yet releasably locking the guard bar in its adjusted position so as to enable it to be quickly and easily adapted to athletes of dilerent facial measurements.

Another object is to provide a helmet-attached horizontal U-shaped face `guard bar device `of the foregoing ICE no modification of the helmet `and to adapt the invention to helmets of different manufacturers.

Another object is to provide a helmet-attached horizonltal U-shaped face guard bar device of the foregoing character wherein the pivot fasteners for the guard bar are mounted either forwardly of the locking fasteners or vice Versa, as desired.

Another object is to provide a helmet-attached horizontal U-shaped face guard bar device, the end portions of which are pivotally mounted on pivot fasteners attached to opposite sides of the helmet and locked in their adjusted positions by locking fasteners which are spaced away from the pivot fasteners in such arcuate relationship as permits adjustment of the face guard bar device into a wide Variety of positions without requiring further drilling or modification of either the helmet or the face guard.

Other objects and advantages of the invention will become apparent during the course of the following description of the accompanying drawings, wherein:

Figure 13 is a horizontal section taken along the line 13-13 in Figure 12.

Referring to the drawings in detail, Figure l showsa helmet, generally designated 10, for athletes or other Sportsmen, equipped with a vertically-adjustable horizontal U-shaped face guard bar device, generally designated 12, attached to the opposite lower sides 14 which extendi downward from the upper or cranial portion`16 of the Patented ocr. 4, 19Go helmet 10.. The latter has thev usual frontal portion 18 with a front lower edge 20 extending downwardly to and around the peripheral edges 22 of the side portions 1-4 which at their rearward ends join the lower rear edge 24 of the cranial portion 16'. Thus, the opposite side portions 1'4 extend downwardly and forwardly from the cranial portion 16 and are ordinarily integral therewith.

In order to adapt the guard bar device 12 to previouslymanufactured or conventional hel-mets 10, it is preferred to form the device 12 in three principal components, namely a guard bar, generally designated 26, and a pair ofJ mounting plates or members, generally designated 28. The mounting plates 28 are secured directly to the depending sides 14 of the helmet 10 by vertically-spaced fasteners 30, such as screws, threaded through countersunk holes 32 (Figure 2) into threaded holes 34 in the helmet sides 14. The mounting plates 28, the opposite end members 36 of the guard element 26 and the opposite. sides '14 of the helmet 10 are provided with aligned holes 38, 40 and 42 respectively, the latter being threaded for reception of threaded pivot fasteners 44 upon which the guard element or U-shaped bar 26 is pivotally mounted for upward or downward swinging relatively to the mounting plates 28.

The guard bar 26, as previously mentioned, is of approximately U-shaped form, preferably of transparent plastic material, with the slightly widened opposite end members 36 interconnected by a slightly narrower integral arcuate intermediate or bridge portion 46. The rearward ends of the end members 36 are provided with looking fastener holes 48 spaced rearwardly away from the pivot holes 38 and adapted to receive threaded locking fasteners 50 which vpass through arcuate undercut slots 52 centered at their respective pivot fastener holes 40 and having undercut broadened arcuate portions 54 receiving correspondingly-shaped clamping nuts 56 into which the threaded ends of the locking fasteners 50` are threaded. The clamping nuts 56 preferably have arcuate convex or concave opposite edges S and 60 slidably tting the opposite arcuate convex and concave edges 62 and 64 of the undercut portion 54 of the slot S2.

Rearwardly of the locking or clamping fasteners S0, the ends of the end members 36 of the guard bar 26 are provided on their inner surfaces with an arcuate row of teeth or serrations 66 which mesh with corresponding teeth 68 on the rearward end portions of the mounting plates 28 so as to efectively prevent swinging of the guard bar 26 relatively to the mounting plates 28 when the clamping fasteners 50 have been tightened, as explained below in connection with the operation of the invention. i

The modified guard bar device, generally designated 70, shown in Figure 5 is of similar but reversed construction in comparison with the device 12 of Figure 1. As before, the guard bar, generally designated 72, is mounted` on mounting plates or members, generally designated 74, by means of pivot fasteners 76 similar to the pivot fasteners 44 but threaded through holes 78 near the rearward ends of the end members 80 of the guard bar 72 which, as before, has a narrower intermediate or bridge portion 82 interconnecting the opposite end members 80. The pivot fasteners 76, as before, are threaded through the pivot holes 78 and aligned holes (not shown) similar to the holes 40 of Figure 2 into threaded aligned holes in the helmet side portions 14 into the threaded aligned holes 42 ofV Figure 2.

The mounting plates 74, as before, are drilled at vertically-spaced locations to receive mounting fasteners 84 which are threaded therethrough into aligned holes (not shown) in the helmet sides 14 similar to the holes 34 of Figure 2. The forward ends of the end members 80 are drilled for the reception of threaded locking or clamping fasteners 86 in arcuate undercut clots 88 similar to the arcuate undercut slots 52 and `similarly centered on the pivottfastener holes 78. The locking or clamping fasteners 86 are similarly threaded into arcuate-sided clamping nuts 90 similar to the clamping nuts 56 of Figure 2 andl similarly slidingly engaging the undercut portion of the arcuate slot 88. The end members 80 of the guard bar 72 adjacent their junction with the intermediate or bridge portion 82 are provided on their under or inner surfaces with teeth or serrations 92 disposed in an arcuate path and meshing with similar teeth 94 also arranged in an arcuate path on the outer surface of each mounting plate 74.

in the operation of either the guard bar device 12 or the modified guard bar device 70, the forward portion 46 or 82 of the bar 26 or 72 is swung upward or downward to adjust it to the differing facial characteristics of different wearers by loosening the clamping fasteners 50 or 86 relatively to their respective clamping nuts 56 or 90, until the interlocking teeth `66 or 68 of Figure 2 or 92 and 94r of Figure 5 `can be disengaged. With these teeth thus disengaged, the guard bar 26 of Figure 2 or 72 of Figure 5 can Ibe swung upward or downward relatively to its respective mounting plates 28 or 74 to theY desired position most effective to give facial protectionv to the particular wearer to whose facial characterisitcs it is being adjusted. The operator then tightens the. clamping fasteners 50 or 86, as the case may be, causing the arcuatelyarranged teeth 66, 68 of Figure 2 or 92,V 94, of Figure 5 to re-engage in meshing relationship with one another, thereby effectively locking the guard bar 26 of Figure l or 72 of Figure 5 lirmly in its adjusted position. VReadjustment is accomplished by a reversal of the foregoing procedure, thereby enabling a single helmet and face guard to be used by many different, players regardless of varying facial dimensions or characteristics.

It will be understood that in a factory-manufactured combination of helmet and guard bar, the separate mounting plates 28 or 74 may be dispensed with and made integral with the side portions 14, either raised therefrom or flush therewith, with their respective teeth formedV in corresponding locations to the locations shown in Figures l and 5.

The further modified adjustable helmet-attached U- shaped face guard bar device shown in Figures 6 and 7, provides aligned threaded fastener holes 102 in the opposite lower sides 14 of the helmet 10 and also aligned threaded locking fastener holes 104 spaced forwardly of the pivot fastener holes 102 (Figure 7), these holes 102 and 104 receiving pivot fasteners 106 and locking fasteners 108 respectively. The pivot fasteners 106 pass through counterbored unthreaded holes 110 aligned with the threaded fastener holes 102 and formed in the opposite end members 112 of an approximately U-shaped face guard bar, generally designated 114, the forward portion 116 of which is arcuate and serves as a' bridge portion integral with and interconnecting the end members 112. The locking fasteners 108, on the other hand, pass through an arcuately-arranged series of interconnecting unthreaded holes 118, the centers of which lie upon a circular arc concentric with the pivot fastener holes V and possess an arcuate recess or counterbore 119 for the head of each locking fastener screw 108.

In the operation of the device 100, the fact guard bar 1'14 may` be swung upward or downward relatively to the helmet 10 by removing the locking screws 108 from their holes 104 and 118, then swinging the bridge'portion 116 upward or downward around the pivot fasteners 106 until the desired position is reached, at which one of the interconnected holes 118 is in alignment with the locking fastener hole 104 in each lower side portion 14 of'the helmet 10. The operator then reinsertsV the locking fasteners or screws 108 in the new holes 118 and again threads them into the threaded holes 104, tightening the headsV of the screws 108 against the bottoms of the arcuate counterbores or recesses 120 in order to firmly clamp the guard bar'114 in its newly adjusted position.

'Ihe still further modified adjustable helmet-attached U-shaped face `guard bardevice, generally designated `120, shown in Figures 8 and 9 is generally similar to the device 100 shown in Figures 6 and 7, except that the positionsof the pivot fasteners and locking fasteners are reversed. Accordingly,` the same reference numerals, followed by the sutiix a have been applied to corresponding parts., The operation of the still further modified device 120 is substantially the same as that of the further modified device 100, with the exception of the reversed locations Yof the pivot fasteners and locking fasteners, hence requires no repetition.

" 'The additionally Amodified i` adjustable helmet-attached U-shaped face guard bar device, generally designated 130, shown in Figures 10 and l1, is generally-similar to the devices 100 and 120 and is in elfect a combination of the devices 100 and 120. Accordingly, the same reference numerals, followed by the suffix b have been applied to corresponding parts, with the exception of the fact that reference numerals followed by the sutix c have been applied to the additional rearward arcuate group of Unthreaded locking fastener holes, which are out of alignment with their respective threaded locking fastener holes when the forward Unthreaded locking fastener holes are in alignment with their respective threaded fastener holes. Thus, each pivot fastener and set of pivot fastener holes are located between the pair of arcuate groups of Unthreaded locking fastener holes.

In the operation of the additionally modified device 130, to adjust the guard bar 114b relatively to the hehnet 10, the operator, as before, removes the locking fastener screws 108b and swings the guard bar 114b upward or downward until it is located in the desired position, whereupon the operator reinserts the locking fasteners 108b in whichever of the Unthreaded locking fastener holes 118b and 119e` that happen to be most nearly in i:lignment with their respective threaded locking fastener oles. i

The other modilied adjustable helmet-attached U- shaped face guard bar device, generally designated 140, shown in Figures 12 and 13 is generally similar to the device 130 of Figures 10 and 1l, except that the pivot fastener screws are placed in one of the arcuate groups of holes and the locking fastener screws in the other group thereof. Accordingly, the same reference numerals, followed by the prefix d have been applied to corresponding parts, with the exception of the fact that reference numerals followed by the suiiix e have been applied to the additional rearward arcuate group of unthreaded locking fastener holes. It will be obvious from Figures 12 and 13 that either the forward or rearward threaded hole may serve as a pivot fastener hole or as a locking fastener hole, according to the preference of the operator and the amount of adjustment required. If, for example, the forward screws are used as pivot fastener screws and therefore designated 106d, the rearward screws become locking fastener screws and are therefore designated 108d.

In the operation of the other modied face guard bar device 140, the operator removes either the pair of screws 106d of the pair of screws 108:1, but not both, causing the pair of screws remaining in their threaded holes in the lower helmet portion 14 to act as pivot fastener screws, the other pair of screws being reinserted when the desired adjusted position of the guard bar 114d has been reached. It will be seen from a consideration of the principles of levers that when the rearward screws 108d are used as pivot screws, the front of the guard bar 114d cannot be swung upward to as great an angle as when the forward screws 106d are used as the pivot screws, and still be able to insert the locking screws through one of the holes in its respective arcuate group ofholes.

` 'I'he modified forms of the invention designated as the guard devices 100, 120, and 140 are less expensive to make than the devices 26 or 7 0 respectively of Figures 1 and 5. The threaded screw holes in the lower 'side portions 14 of the helmet 10 would preferably be predrilled and prethreaded at the helmet factory and hence would be located in positions which would not give as wide a range or gradation of adjustment as in the case of the subsequently applied devices 26 and 70 of Figures l and 5 respectively.
