Application June 1, 1956, SerialNo. 589,703! 5 Claim. or. 2-42).

The present invention relates to improvements in protective apparel and more particularly to apparelaffording protection against impact to" the body. Specifically, the invention pertains to improvements in shin guards:

In certain types of occupations, as in railroading and other such work, one encounters many instancesin which the body is subjected to excessive impact against" objects or from accidental blows or the like, and particularly blowson theshiiis. Previously known shin guards for use in such instances have not been entirelysatisfao tory from the standpoint ofprovidi'ng maximum protection with minimum discomfort.

An object therefore of the present invention is to provide a shin guard having novel construction of such nature that it provides maximum protection with mi'ni mum discomfort.

Another object is to aiford a shin guard having a novel construction including a steel piece for maximum protection.

A further object is to provide a shin guard having novel laminated construction, including a steel layer or lamina, providing great strength While being unusually light.

A still'further object is to afford ashin guard of laminated construction having an inner resilient layer and arr-outer steel layer providing hardnessand toughness as against external blows but providing a cushioning effect against the body of the wearer.

Another object is to provide a shin guard having a relatively rigid portion covering the shin but an entirely flexible supporting portion engaged" with the legya'bove the knee, thus providing completefreedom of'the leg in bending at theknee.

A- still further object isto provide a shin guard of the general character noted above having a covering of leather providing resistance to sending and similar ac tion while also being arranged in a novelrnanner toprovide flexible flaps which" surround that portion of the leg not surrounded by the rigid steel" shin covering portion.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel features of construction; arrangement and a combination of partshereinafter fully'described, illustrated in. the accompanying drawings, and particularly pointed out in the appended claimsyit being understood that various changes in the form; proportion, size and minor details of the structure-maybe: made without departing from the spirit or sacrificing any of the advantages of the invention.

For the purpose of facilitating an understanding of my invention, I have illustrated in the accompanying drawing a preferred embodiment. thereof; from any inspection of which, when considered in 'connectiomwith the following description,.my invention, its mode ofconstruction,. assembly and operation, and many of its-ad,- vantages should be readily understood and appreciated? Referring to the drawings in'whi'ch the" same characters of reference are employed to indicate corresponding 2. or similar parts throughout the several figures of the drawing:

Fig; l. is a side elevationalview of the novel shin guard of theinventionappliedtothe wearer;

Fig. 2 is an elevational view from the rear, with a. portion of the' fiaps broken away;

Fig". 3 is atop plan'view', with-a part ofthe' rigid shincovering portion broken away; and

Fig; 4 is an enlarged detail view in section of the portion encircled in dot-dash linesin' Fig. 32

Referring now in detail to the drawings, reference numoral IO 'i'ndicates generallytlre shiir guard as shown in Fig. l and as applied to the leg of the wearer; It in eludes; as principal members, ashin coveringportion I2, rear flaps 1'4 and 16; and a supporting portion indicated generally at 18' engaging the leg above'the knee;

Theshin-coVering member, org'uardpro'pe'r, IZafiords themajpr portion of theprotectionagainst excessive impact and hard blows, and accordingly is of rigid and tough construction. This portion includes a layer or lamina 20 of hard tough material suc'li' as steel and a layer or lamina 22' of resilient material on itsinn'er'surfacet Preferably such material" may comprise sponge rubber. The rubber layer 22 is slightly larger in area than the steellayer' and'extends beyondthe" edges of the latter; whereby to prevent the edges of the steel from digging or gouging into the leg; These layers are preferably secured together by suit-ahlemeans, such as by an adhesive'or bonding material or hyvulcanizing'; The shin covering portion 12" is of suitable shape and diinen sinus to cover the front portion of the lower legamaxi mum extent consistent with other considerations; such as'comfort and freedom of movement. For example, in circumferential direction, it encompasses substantially half the leg so as not to" produce a bind'ing effect on the call;-

The guard proper portion 1*2 has a projection or tongue 2'4 extending down over a portion of the instep, of such size and shape as to cover as much ofithe' instep as possible without interfering with the" fie'xihg of: the footnin" walking; It will be understoodthat the "shape and dimensions mentioned above" are those-considered with respect to any given size, since there maybe a' number of different sizes, i. e.', a large guard for a large person,

a small one for small person; etc Atany 'rate in any given size, the. guard should cover as much of the leg es -possible! without impairing freedom of movement:

It is desired to have the steel layer" 20 embedded in the-midstlof other noxnsteel layers Tothis end", ala'yer of leather-likematerial 25' is applied"to'theoutefsurface of the steel layer. This layer is preferably ofi the same dimensions as: the: resilient layer 22 and hence slightly larger than the steel layer. It is preferably secured to the steel as by. gluing or thelike;- andits outer perimeter portionis similarly secured to the resilient layerrZZi The layer 25; and theouter covering layers; 26 and 28 described in detail hereinhelow; are: of leather-like material, i. e., they may be of: actual leather; imitation leather, impregnated fabric,. such as"; rubberized or leatherized fabric; The' material isvfieriible; tough. and highly wear-resistant; andlen'ds itself well t'o fabrication such as is desirable-in constructing an article such as the guard; for example, it enables effective lamination of plural layers of itself and of-layers' ofothermaterial such as the steel. and rubbern r The layers described hereinabove;. namely,x steel 20, iubber ZZand leather 25,1 togethen form the body orcore of the guard proper, and substantially determine the dimensions thereof. The steel-rubber-leather laminated core construction is enclosed in a casing, of additional layers consisting, or theouter' covering 216 and the inner covering" 28 mentioned hereinahove: material is 'tion in localized areas.

not only strong and tough, but provides a pleasing appearance. These leather covering layers are secured together around and beyond the edges of the core by suitable means, such as by stitching. They need not be otherwise secured to the core unless desired. These covering layers are extended rearwardly beyond the side edges of the core to form the flaps 14 and 16 referred to above. ,These extended portions, on each side may be secured together, as by stitching, along the edges of the core, butneed not be secured together beyond that unless so desired. The fiaps are of suitable circumferential extent, preferably so as to completely cover the calf in addition to actually overlapping a substantial extent.

Hooks 29 may be secured to the shin-covering portion 12, along the lateral edges thereof, as by stitching. These hooks provide means for tying the guard by means of ties or laces such as 30. The stitching preferably is only in the outer layer 26, for convenience and economy in fabrication, although it may be extended through the complete lamination with the exception of the steel layer. The layer 26 is of sufficient strength to support the hooks for the purpose intended. The laces are hooked on the hooks,'in a customary manner, over and bearing on the flaps 14 and 16. If desired, the laces may be laced from the top down and the free terminal portions wrapped around the leg to secure the extremities of the trousers.

The leather coverings Z6 and 28 may be extended above the steel-rubber-leather core as at 32 to provide a certain degree of protection to the leg at that location, and also to provide a finished appearance; the outer layer .of leather being turned over the edge of the core. A similar construction may be utilized at the side edges, as at 34, and at the bottom edge. This arrangement, in addition to providing a finished appearance, enables the flaps to extend circumferentially directly from the inner surface of the guard proper, as clearly illustrated in Fig. f the drawings.

In addition to the portion 32, the

leather coverings

26 and 28 are extended at the top to provide upwardly extending side straps 36 having loops 38 in their upper ends; the loops being formed in any suitable manner, as

-by stitching. A band or strap 40 is threaded through the loops and encircles the leg, to form the flexible supporting means 18 referred to above. The band 40 is provided with a suitable adjustable means such as the buckle 42.

This flexible supporting means engages the leg above the knee and effectively prevents the guard from slipping or sinking. This construction is of particular advantage in preventing the tongue 24 from resting on the instep and thereby interfering with walking. The supporting means 18 is entirely flexible and enables full freedom of movement of the leg and bending of the knee, notwithstanding I of the guard, the weight of the whole article is materially minimized, in keeping with comfort considerations.

The steel sheeting of the gauge mentioned hereinabove is of substantial strength so as to withstand deflec- Thus the force of any blows struck thereon is distributed over a wide area and is absorbed by the rubber layer over that area. Hence, the guard has considerable cushioning eifect. The steel is also capable of being flexed at the sides in response to transverse forces. However, in the front arcuate portion, flexing and deflection are strongly resisted.

The laminated structure of the. guard also contributes to the unusual strength thereof; the leather covering layers "26 and 28 providing a great degree of' strength. The leather covering layers also are tough and withstand scufling action. The inner leather layer 28 in addition to having the qualities mentioned above, also provides as smooth a covering as may be desired for the rubber layer 22 which may have a relatively adhesive surface because of its resiliency characteristics. It furthermore provides protection to the rubber layer against excessive wear caused by rubbing on the trousers. Furthermore, the leather covering layer affords a more comfortable touch sensation to the skin so that the guard may be worn directly on the bare leg. In addition, the flaps 14 and 16 provide a protective and comfortable covering to the calf especially when the guard is applied to the bare leg.

It is believed that my invention, its mode of construction and assembly, and many of its advantages should be readily understood from the foregoing without further description, and it should also be manifest that while preferred embodiments of the invention have been shown and described for illustrative purposes, the structural details are nevertheless capable of wide variations within the purview of my invention as defined in the appended claims.
