U.S. Patent ARM PROTECTING DEVICE This invention relates generally to new and useful im provements in protective arm pad devices, especially for use in sports. The invention was made having in mind particularly providing protection for lacrosse players, but is of more general application in connection with sports involving bodily contact.

BACKGROUND OF THE INVENTION In many athletic sports, players are subjected to body contact either with other players or with game equipment, such as lacrosse sticks. The prior art has pro vided various kinds of arm protective devices which may be used in such sports. Examples are to be found in the patents to Sotherlin U.S. Pat. No. 3,322,118 and Enicks U.S. Pat. No. 3,446,880, which disclose arm protective devices intended to protect the wearers elbow and portions of the wearers biceps andforearm. The Sotherlin patent discloses a rubber pad for protecting the elbow point. The Enicks patent discloses a pad formed of plastisol provided with an outer skin. Various arm protective devices including some comprising a plurality of parts have been proposed in the prior art. The prior art arm protective devices known to the applicants are believed not to have all that is desired from the standpoint of a balancing of the factors of light weight, ample protection of the biceps, forearm and elbow, resilience and flcxibilty, and adaptation to being fitted to an individual wearers arm, from the standpoints of providing protection, comfort or feeling to the wearer, and minimum interference with free arm movement.

SUMMARY OF THE INVENTION The present invention seeks to provide an arm protecting device having improved qualities as to weight, protection of the biceps, forearm and elbow, resilience and flexibility, allowing relatively free arm movement, and ease of fitting to the individual wearers arm. A general object of the invention is to provide such an improved arm protective device comprising a flexible, resilient, cushioning pad which is so contoured or shaped as to be capable of being wrapped around a wearers arm and fitted with considerable individuality respectively to the biceps, forearm and elbow.

Another object of the invention is to provide an arm protective device including a flexible pad which may be flattened out relatively in a non-use position and which includes an elbow portion intervening between and connecting a forearm portion and a biceps portion, the pad having two longitudinally spaced parts between the elbow portion and the biceps and forearm portions, respectively. which are of less lateral extent than the biceps and forearm portions, the pad parts of less lateral extent contributing to the capability of the biceps, forearm, and elbow portions being shaped individually to the arm.

Further objects of the invention will be apparent from a reading of the following description, the claims, and the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings: FIG. 1 is a perspective view of an arm protective device embodying the invention, shown formed substantially as it would be when applied to the arm of a wearer;

FIG. 2 is a plan view of a pad which is part of the device, shown flattened out;

FIG. 3 is a cross-section on the line 33 of FIG. 1;

FIG. 4 is a perspective view of the device in place on a wearers arm, straightened out; and

FIG. 5 is a perspective view of the device in place on a wearers arm, bent at the elbow.

DETAILED DESCRIPTION The embodiment shown in the drawings for illustrating a preferred form of invention comprises a unitary pad P of flexible resilient material which may be deformed from its relatively flattened-out, non-use condition shown in FIG. 2 to the relatively wrapped-around positions shown in FIG. 4 and 5 in use as applied to a wearers arm, and means, generally designated SMl, SM2, 5M3, SM4 and SM5, for shaping the pad to conform substantially to the wearers arm.

The pad P comprises a relatively thick body or core C of flexible, resilient, cushion material and a relatively thin coating or skin S (indicated in FIG. 3) which is preferably relatively smooth as compared to the material of the core C were it not covered by the skin S. A presently preferred material C comprises a closed cell rubber, and the skin S may comprise closed cell polyvinyl chloride material the cells of which are more closed than those of the core C. The skin may be applied to the core by dipping the latter in the skin material, the skin thereafter being cured to provide a smooth surface for the pad. The core C desirably has a compression deflection of 48 p.s.i. (ASTM D-l056-68), a density range (PC F) average 5l0, a water absorption range up to 10% maximum by weight, a compression set of 50% (average) in a test sample one-half inch thick compressed 22 hours at F. with a recovery of 15-25% in 24 hours. Linear shrinkage is a maximum of 5% when aged 7 days at 158F. The aforesaid properties are retained under relatively sustained temperature exposure from 20F. to F. and under intermittent short exposure to 200F. A suitable and presently preferred material is closed cell rubber R-3l0-V dip coated with vinyl SBE-4l-42, a polyvinyl chloride, pro vided by Rubatex Corporation Division of Groendryk Manufacturing Company, Incorporated, of Buchanan,

Virginia.

Dimensions of the pad may vary according to different arm sizes. In a typical pad, the thickness is one-half inch and the maximum longitudinal dimension is ap proximately 17 inches. Generally, the same thickness may be employed for pads of somewhat different lengths.

Referring particularly to FIG. 2 which shows the pad P in its flattened non-use condition, the pad comprises three main portions longitudinally generally in line with each other, namely a biceps portion BP, a forearm portion FF and an elbow portion EP, all formed integrally and of lateral and longitudinal extents sufficient partially to encompass a wearers arm. The flattened-out pad P is contoured in outline to enable the biceps por tion BP, the forearm portion FP and the elbow portion EP to be shaped in place separately to a wearers biceps, forearm and elbow, respectively. The elbow portion EP is constituted by a main or central part EP] and two ears EPZ and EP3 of modified triangular shape projecting outwardly from the central part EPl, the ear EP2 being longer than, that is it extends laterally out.- wardly more than, the ear EP3. The biceps portion has two lateral edge parts or portions BP] and BP2. The forearm portion FF is shown as and may usually be substantially a mirror image of the biceps portion BP.

The elbow portion generally designated EP intervenes between the biceps portion BP and the forearm portion FF, and the ears EP2 and EP3 extend oppositely outwardly from the laterally opposite sides of the central part EPl of the elbow portion EP.

Relief spaces R1, R1 in the periphery of the pad intervene between the ear EP2 and the laterally extending side parts BPl and PM of the biceps portion BP and the forearm portion FP, respectively. The relief spaces R1 facilitate separate or more or less individual shaping of the laterally extending parts BPl and FF] and the ear EP2 to different portions of a wearers arm when applied. Thus, each part BPl and FPl and the ear EP2 may be deformed differently from the deforming of the other two of these parts according to the configuration of the wearers arm and the wearers individual preference as to fit, having regard both to comfort and to secureness in place.

Along the other longitudinal side and in the periphery of the pad are relief spaces R2, R2 between the ear EP3 and lateral side edge parts BP2 and FP2 of the bicepsportion BP and the forearm portion FP, respectively. The ear EP3 is somewhat shorter laterally and more narrow longitudinally of the pad than the ear EP2. The relief spaces R2 are convergingly narrower from the outer end of the ear EP3 toward the central part EPI of the elbow portion EP and terminate in roots RO which are wider than the narrowmost parts of these relief spaces. The wider roots cause more efficient distribution of stress in the pad material when the parts BP2 and FP2 and the ear EP3 are curved or otherwise formed to different extents when beingapplied toa wearers arm, thus inhibiting splitting or other fail ure of the pad material adjacent the relief spaces R2, R2.

As may be seen in FIG. 2, the pad P, formed as outlined above, includes two longitudinally spaced pad parts (unnumbered) which are located between and merge with the elbow portion EP and the biceps and forearm portions BP and PP, respectively, these pad parts being of less lateral extents than the biceps portion EP, the forearm portion PP and the elbow portion EP considered in it entirety as including the central part EP! and the ears EP2 and EP3. These two pad parts of less lateral extents contribute to the ease of shaping the portions BP, FF and EP to fit the wearers arm.

As shown in FIG. 2, center lines CL'of the biceps portion BP and the forearm portion FP intersect within the central part EPl of the elbow portion EP at an obtuse angle a.

Reference will now be made to the shaping and securing of the pad portions BP, FF and EP to the wearers arm. Desirably, separate shaping and securing means are provided for use in connection with the pad portions BP, PP and EP. In the form shown separate straps SMl-SM5, which advantageously may be elastic, are provided.

The pad biceps portion BP is formed with four slits, two being near the free end of the portion BP, and the other two 11 being adjacent the merging of the portion BP with the elbow portion EP. The elastic straps SM] and SM2 are threaded through the slits 10 and 11, respectively, and extend across that face of the pad which is to be positioned next to the wearers arm. The straps SMl and SM2 are looped from the opposite face of the pad with their ends being closed adjustably by double ring type buckles or fasteners 12 of a known kind. Both rings of each fastener 12 are attached at 13 to one of the associated strap ends, the other strap end being passed through both rings and returned to extend under one only of the pair of rings. The length of the.

looped straps may thus be adjusted by manipulation of the strap free ends in the rings in a well known manner. In this way, the biceps portion BP may be shaped readily to conform to the wearers biceps.

The forearm portion FF is formed with slits 10 and 11 positioned relatively to the portion .F P similarly to the positioning of the slits l0 and 11 in the biceps portion BP. The straps SM4 and SMS are extended through the slits l1 and 10, respectively, and are arranged in loop form similarly to the straps SMl and SM2 as described above, again double ring fasteners 12 being provided.

The securing strap SM3 for the elbow portion EP does not pass completely around the pad so itself to constitute a complete loop. Instead, it extends across and spaced from that face of the pad which is to be next to the wearers arm, and its ends extend only against the edge portions of the opposite face of the pad and thence through slits l4, 14 shown in FIG, 1. The ends of the strap SM3 are formed in the shape of a T. To insert the strap SM3 in the slits 14, either one of the T- shaped ends is flexed to align the cross of the T with the slit 14, enabling the strap to be inserted through both slits and placed in the position shown in FIG. 1. The initially inserted T=end of the strap is then restored to the transverse position shown in FIG. 1 so that the strap SM3 is relatively permanently attached to the ear portions EP2 and EP3 of the elbow portion EP.

To apply the arm protective device to a wearers arm, the straps SMl, SM2, SM4 and SMS with discontinuous ends may be loosened. The wearers arm is then extended lengthwise through the looped straps SMl, SM2, SM4 and SMS and between the strap SM3 and the elbow portion EP. Then the straps 8M1, SM2, SM4 and SMS are adjusted so as to conform the biceps portion BP and the forearm portion FP to the wearers biceps and forearm, respectively. If desired, the straps held in loop form by the buckles 12, or some of those straps, may be disconnected by the buckles so as to assist in applying the pad to the wearers arm.

The pad P is shown provided with ventilating holes V. The pad core C may be die cut to its outline and to form the

slits

10, 11 and 14 and the holes V, and the skin S then applied as described above to cover the walls of the slits and the ventilating holes as well as the core surfaces.

As stated above, a typical pad of one-half inch thickness has a maximum longitudinal dimension of approximately 17 inches. In such a pad, the maximum transverse width of either or both of the biceps portion BP and the forearm portion FP is approximately 6 /2 inches, and the tip-to-tip transverse width of the elbow portion is approximately 9 /2 inches. In larger or smaller pads, the dimensions would be substantially in the same proportions.

A device according to the invention is light and readily adjusted to the individual wearer, both from the standpoint of comfort of fit and the standpoint of providing good protection against blows which maybe encountered in sports, particularly in sports involving contact such as lacrosse. At the same time, the pad is so conformable to the wearers arm as to protect a maximum area of the arm with a minimum of interference ,with free arm action. Thus, the reduced lateral extent of the central part B?! of the elbow portion EP taken in connection with the reduced areas of the ears EPZ and EP3 minimizes interference with bending of the wearer's elbow while at the same time providing the necessary protection of the elbow point. In the illustrative embodiment, the pad is symmetrical from end-toend. By having it substantially symmetrical, it is equally applicable to a right or a left arm by being reversed end-to-cnd.

The arm protective device shown embodies the invention in a preferred form, but the disclosure is intended to be illustrative rather than definitive.
