ADJUSTABLE TRUSS PAD.

Fil'ed Jan. 10, 1956 gwucm bom (75H/v (LE/7. SHAW Patented Mar. 9, 1937 UNITED STATES PATENT OFFICE 2 Claims.

The invention aims to provide a new and improved truss pad which may be easily adjusted to obtain the desired pressure at any required point without the necessity of having the pad-carrying strap as tight around the body as now required.

A further object is to provide a novel construction whereby the pad may be quickly and easily adjusted forwardly or rearwardly with respect to the belt, according to the requirements.

Another object is to provide novel means for rearwardly pressing a restricted part of the bodyengaging portion of the pad to provide a convex projection thereon adapted to hold internal parts of the body against outward movement into a rupture, allowing the rupture to heal.

Yet another object is to provide a construction which may be easily and inexpensively manufactured, may be sold at small cost, may be easily adjusted by the wearer, and will afford a 00 maximum amount of comfort.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying draw- 5 ing.

Fig. l is a top plan view showing two of the improved pads mounted upon a belt, showing different adjustments of said pads.

Fig. 2 is an enlarged central sectional view 30 through one of the pads on line 2-2 of Fig. 1.

Fig. 3 is a perspective view of the front plate which is secured to the belt.

Fig. 4 is a perspective View of the flanged disk which is adjustably threaded upon the front plate, and the cup adjustably mounted on said disk.

Fig. 5 is a perspective View of the dome-shaped elastic pad which is connected with the aforesaid disk and abuts a resilient body held by said cup.

. Two of the pads are shown connected with a conventional leather-covered steel belt B whose ends are connected by a strap S, said belt being provided with the usual spaced openings to facilitate attachment of the pads. As both pads are of identical construction, only one will be described.

I provide a front plate 8 for attachment to the belt B, said plate having a threaded edge 9. This plate is attached to the belt by a short 50 bolt ill whose nut H is held by ribs I2 on said plate. This plate is held against rotating about the bolt iii, by suitable lugs 53 which are formed on the front side of said plate and abut the upper and lower edges of the belt B.

55 Behind the front plate 8 is a disk l4 whose front side is provided with a continuous flange I5 having internal screw threads l6 engaged with the screw threads 9 of the front plate 8, so that said disk i4 may be adjusted forwardly or rearwardly by rotating it. The rear side of the disk 14 is provided with a continuous undercut flange H which engages and holds a flange I8 on the edge of an elastic dome-like pad l9, this pad being formed from rather soft rubber.

Mounted upon the central portion of the disk l4 and disposed behind this disk, is a cup 23 which is of much smaller diameter than said disk. A yieldable body 21, preferably a small sponge rubber ball, is held in the cup and projects rearwardly therefrom into contact with the central portion of the dome-like pad l9, said central portion being preferably thinner than the remainder of said pad. Provision is made for forwardly and rearwardly adjusting the cup 20 as may be desired, and the more this cup is rearwardly adjusted, the harder it forces against the central portion of the pad IS, with the result that said central portion may be forced rearwardly to form a small convex projection 22 to press upon the users flesh directly in line with the rupture so as to effectively hold internal parts of the body against outward movement into said rupture, allowing the latter to readily heal.

In adjustably mounting the cup 20, I provide screw threaded adjusting means so that said cup may be adjusted forwardly or rearwardly, simply by rotating it. In the present showing, a stud 23 is centrally secured at 24 to the disk I4 and. projects rearwardly from said disk, the cup 20 being threaded upon said stud as shown at 25.

By rotating the flanged disk with respect to the front plate 8, said disk, the dome-like pad [9, and parts within this pad, may be bodily adjusted forwardly or rearwardly as required. By disconnecting the pad l9 from the disk M, the cup 20 is accessible and. by rotating this cup, it may be adjusted forwardly or rearwardly to suit the exigencies of the case. The pad l9 may then be readily reconnected with the flange ll simply by snapping its flange l8 into engagement with said flange II.

It will be seen from the foregoing that novel and advantageous construction has been provided for carrying out the objects of the invention. While preferred details have been shown, variations may be made within the scope of the invention as claimed. Moreover, any desired material or materials suited to the purposes which they must fulfill, may be employed, and the sizes and proportions of parts may be varied within a wide range.

I claim:

1. In an adjustable truss pad, a front plate for attachment to a belt, a disk behind said front plate and having a threaded connection therewith to allow forward and rearward adjustment of said disk by rotating the same, a rearwardly open cup behind said disk and having a threaded connection therewith to allow forward and rearward adjustment of said cup by rotating it, said cup being of much smaller diameter than said disk, a yieldable body seated in and projecting rearwardly from said cup, and a dome-like yieldable pad enclosing said yieldable body and contacting with the rear side thereof, the edge of said dome-like pad being connected with said disk.

2. In an adjustable truss pad, a disk and means for mounting it on a belt, a rearwardly open substantially hemispherical cup mounted on the rear side of said disk, a substantially spherical elastic body seated removably in said cup and projecting rearwardly therefrom, and a domelike elastic pad enclosing said elastic body and detachably secured to said disk, said dome-like elastic pad being free of connection with said substantially spherical elastic body but disposed in abutting relation therewith to hold said body in said cup.
