Application led February 17, 1928. Serial No. 255,033.

'This invention aims to provide a guard which will protect the lower part of the abdomen of the wearer, against injuries of all kinds, and particularly against groin injuries and against injuries to attendant and nearby parts.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Figure 1 shows in perspective, a device constructed in accordance with the invention;

Figure 2 is a section on the line 2-2 of Figure 1; and

Figure 3 is a section on the line 3-3 of Figure 1.

Figure 4 is a section on the line 4 4 of Figure 1.

In carrying out the invention, -there is provided a front pad 1, in the form of a triangle, the part 1 including a front wall 2 which is made of resilient rubber, and a rear wall 3 which is made of rubberized fabric. The front wall 2 can expand and stretch. The rear wall 3 can flex into any desired curve, but its length remains always the same. Consequently, when the front pad 1 is inflated as hereinafter described, the pad at its lower end tends to curve backwardly and upwardly, as

- shown at 4, thereby t0 conform to the shape of the body of the wearer. The rear edge of the front pad 1 isv increased in thickness, slightly, as shown at 5, so as to provide an additional cushioning and protecting effect against crotch injuries. Partitions 6 are secured along their rear edges to the rear wall 3 and along their front edges to the Afront wall 2. As shown at 7, the partitions 6 do not extend entirely across the front pad 1 from side to side. There is, therefore, space at the end of each partition 6 through which the air can circulate somewhat slowly: that is, if a punch is imparted to the front pad 1, air will not rush away from the immediate place where the punch is delivered, but lwill move somewhat slowly, and it will be impossible to `reach the body of the wearer by any kind of a blow that will not tear the pad to pieces. The partitions 6 not only control the circulation of air within the front pad, but, as well, they afford reinforcement. The partitions 6 `are flexible, and they may be made in any desired way. Sometimes, two layers 8 of material are cemented together, and the edges of the la ers 8 are inclined as shown in Fig-v ure.3 to orm flanges 9 which are-cemented to the front and rear walls of the pad 1.

The device includes an inflatab-letube 10 which extends part-way around the body of the wearer: perhaps to the places marked by the numeral 11 in Figure 1 of the drawings. The tube 10 is connected at the front of the device, by a nipple 12, with the upper part of the front pad 1, so that air can pass from the tube 10 into the front pad. Air is supplied to the tube 11 by means of a valve 14 indicated in Figure 1 of the drawings. The tube 10 has partitions 15, constructed as hereinbefore described, in connection with the part-itions 6, the ends of thepartitions 15 are being spaced, as shown at 16, from the top and bottom portions of the tube 10, as and for the purpose hereinbefore described in connection with the partitions 6.

The circumferential tube 10 may be enclosed within a belt 17, made of any suitable material, the ends of the belt 17 being joined by a lacing cord 18 or any other adjustable means which will answer the purpose. The belt portion of the device merges into a covering 1 9 for the front pad 1, and the rear end of the covering 19 is connected by a strap 20 with the rear portion of the belt 17.

The device is so constructed that it will protect the parts to which itis applied. The device may be madeas bard or as soft as desired, depending upon the amount of inflation. It will assume the curved form shown at 4, owing to the `fact that the rear wall 3 is flexible but not elastic, whereas the front wall 2 is both flexible and elastic. Owing 'to the l the front wall of the pad being made of ilexible elastic material, and the rear 'wall of the pad being made of flexible inelastic material, whereby when the pad is inflated, it will assume a curved form and shape itself to the body of the wearer, means for inflating the pad, and transverse partitions connecting the front Wall of the pad with the rear wall of the pad, the ends of the partitions being spaced from the lateral edges of the pad to provide for a restricted shifting of air when the p ad is subjected to pressure.

2. In an abdominal guard, a front pad of approximately triangular shape, a belt carryi tube and the upper portion of the pad, and

partitions in both the tube and the pad, the partitions terminating short of the edges of the tube and short of the edges of the pad, to provide for a restricted shifting of air Within both the tube and the pad.

In testimony that'I claim the foregoing as my own, I have hereto aixcd my signature.
