KNEE PAD.

Application filed December 10, 1921. Serial No. 521,449.

and useful Improvements in Knee Pads, of

which the following is a specilication.

This invention relates to knee pads, and the purpose of the same is the provision of a knee pad which is constructed to effect, when in use, theforced ventilation of the padding content as well as the knee of the wearer, whereby the heating of the pad and the scalding of the knee and other' parts of the leg is prevented.

lt is also a purpose of this invention to provide a knee pad which includes a container constructed to removably receive cushioning material of any character and to hold the material out of direct contact with the knee, and at the same time to provi-de a resilient seat for the knee.

A further purpose of the invention is the provision of a knee pad havinga novel form of attaching means by which the rigidity of the ordinary fastening straps secured to the sides of the usual form of knee pad is eliminated, an@L the required flexibility provided so that extreme comfort is given to the wearer whether kneeling, standing, bending or walking.

in the accompanying drawings- Figure 1 is a view showing in applied. position one form of knee pad embodying my invention.

Figure 9. is a perspective view of the pad shown in Figure 1.

Figure 3 is a transverse sectional view of the knee pad shown in the preceding views.

Figure 4 is a perspective view of the knee pad shown in Figure 1 and with the cushionknee - ing material and attaching straps removed.

Figure 5 is a perspective of a modified form of the invention.

Figure 6 is a perspective of the improved knee pad open, the iilling being omitted.

Similar reference characters refer to similar parts in each of the several views.

Referring specically to the drawings, the invention in its present embodiment comprises a container designated at l and formed of resilient material such as leather, 'vulcanized canvas, rubber or the like. The container K includes a body portion 15 integrally formed at its longitudinal edges with side portions 16 which are bent to overlie the body portion and having their free longitudinal edges spaced apart to provide an air-gap 17 that is co-eXtensive in length with the body portion.

The side portions are secured together at one end by means of a fastening member 18 so as to permanently provide the gap 17 and to maintain the side portions in overlying l relation with respect to the body portion 15.

By this arrangement, a compartment is formed between the side portions and body port-ions, and this compartment is adapted to receive a cushioning material such as cotton, hair or the like as indicated at 18T- in Figure 3.

At the upper or left hand end of the body portion 15 is provided a hood 19 adapted to embrace the leg at a` point above the lmee as clearly shown in Figure `1. This hood 19 is a continuation of the material comprising the body portion 15, and is formed by bending the hood at right angles to the body portion and securing its vertical edges to the sides of the container by means of rivets 20 or other fastening means. In this manner the hood assumes a curved form and is held in right angular positionwith respect to the container so that it will properly embrace the leg when the pad is in applied position. i

At the opposite end of the body portion 15 and within the pad receivingy compartment a flap 21 is secured by means of rivets 22. rlfhis fia-p is bent so that it overlies the side portions 16 and thus spans the gap 17, and partially closes thelower end of the comlpartment,thus providing means for retaining the cushioning material 18L against dis placement from the compartment. As shown, the flap 21 is perforated for the purpose of permitting the circulation of air into and through the compartment ras will be more fully described hereinafter. For attaching the pad as a unit to the leg of the wearer, two straps S and S are provided. [is shown in Figures' 1 and 2 the strap S is trained through incisions 23 of the hood 19 and is secured to the free end of the flap 21 by a rivet 24. By this arrangement it will be seen that the strapS serves to maintain the flap 21 in covering position with respect to the container so as to prevent displace ment of the cushioning material. The strap S is trained through incisions 25 of the side portions 16, and it is secured to the body portion ,15 by means of. the rivets 22 em.

ployed for securing the flap 21 to the body portion as is clearly shown in Figure 3.

In practice, the pad is attached to the leg in the manner shown in Figure 1 with the straps S and S trained about the leg at points above and below the knee. By virtue of the manner in which they are attached the straps are practically continuous and function in a manner similar to a belt, thereby providing an extremely comfortable attaching means. As the container K is formed of resilient material, it will be clear that because of the arrangement of the side portion 16 with respect to the body portion 15, the container is resilient, that is, after having been compressed under the weight of the leg, it automatically expands to normal position. This expansive movement is enhanced by tne cushioning material 13 within the compartment. .By virtue of this resilient container it is caused. to occupy expanded and contracted positions during the normal use of the pad. For example, in the normal position of the pad, the container, is expanded, but when the wearer is kneeling on the pad it is compressed.

`W hen the wearer rises and the pad is re lieved of the pressure, it expands, thus causing the air to circulate into the pad receiving compartment. The air gap 17 and openings at the opposite ends of the container, provide avenues through which the air is permitted to circulate, While at the same time air is caused to circulate about the knee of the wearer through the erforations of the flap Q p i 21, every time the knee is put down and raised up. This method of ventilation obviously prevents heating of the cushioning material and scalding of the knee, so that a comfortable knee pad is at all times assured.

It is to be particularly noted that the cushioning material 13a is removable from the container. This permits of the substitution of new material when the old becomes packed and hard, and it is of special advantage to cotton pickers as the cotton can be used for the cushioning material and the picker can readily substitute new cotton while working` in the field.

1n view of the foregoing, it is thought that the operation of the device will be readily apparent and in view of the simplicity and practical value that it will readily commend itself to those skilled in the art.

As illustrated in Figures 5 and 6, the im proved knee pad may be' formed from a single blank of yieldable material designated by the numeral 30 and which is provided' with oppositely arranged transverse incisions 31 intermediate its ends, which define intermediate wings 32 and end wings' 33, the

end; wings 33 being adapted. to. overlap the intermediate wings 32 so that rivets 34 may be extended throughv the aligned apertures 35 and 3e. WhenthewingsSQ endehave thus been connected, the portion of the body between the incisions 31 is partly folded or turned so as to provide an end wall 37 which joins the side walls formed by the

wings

32 and 33. The side walls formed by the

wings

32 and 33 and the end wall 37 formed between the wings 33 defines a pocket for the reception of a filling element or cushioning member carried by a filler to be described.

At one end of the body 30 the same is provided with an extension 40 having laterally extending sides 41 between which a cushioning element is adapted to be arranged. When the cushioning element has been arranged upon the extension A40 and between the sides 41 said sides may be connected by means of fastening devices 42 of any suitable character. The fastei'iing devices 42am extended through openings in the edge portions of the sides 41 and maintain the longitudinal edges of the sides 41 in spaced parallel relation, therebv providing a means to permit the passage of air through the cushioning element. lVhen the cushioning element has thus been secured within the holder for the salme, the holder is folded into the pocket formed by the

wings

32 and 33 and the end walls 37 and the holder for the cushioning element is held within the pocket by means of an attaching strap 40 passed through longitudinally extending incisions 45 in the extension 40.

The strap 44 is also extended through the diagonally extending incisions 47 in the terminal portion of the wings 33. One end portion of the strap 44 is provided with a buckle 48 through which the free end portion of the strap is extended when the improved pad is applied to ones knee.

The lower portion of the pad is held in position by means of a strap 49 passed through longitudinally extending incisions 5() in the side wings 32.

It is thus seen that the attaching strap 44 not only serves as a means for securing the pad to ones knee but also as a means for scouring the cushion holder within the pocket provided by the several wings in the end wall 37. yIn order that the pad might be thoroughly ventilated the extension 40 is provided with a series of apertures 56 through. which the air may pass.
