Aug. 21, 1962 s. GRASSI.

CERVICAL COLLARS Filed Jan. 4, 1961 2 mu F s4 INVENTOR.

Simon Gruss! FIG AT T0 R N EY- nite taes 3,050,052 CERVICAL COLLARS Simon Grassl, 1561 3rd Ave., New York, N.Y. Filed Jan. 4, 1961, Ser. No. 80,655 4 Claims. (Cl. 12S-75) This invention relates to new and useful improvements in cervical collars, and it has after long research and experience been so constructed as to eliminate certain defects found in most of the collars now commonly used.

Thus some of the definitely outstanding meritorious and advantageous features of the present invention are the utmost simplicity of adjustment of said collars as to height without any sidewise wabbling of the sections which constitute the parts of these collars, and next the stiif and high supporting rear neck-portion of the collar of this invention.

With the above and other objects in view, this invention consists of the novel features of construction, combination and `arrangement of parts, hereinafter fully described, claimed and illustrated in the accompanying drawing, forming part of this specification, and in which similar characters of reference indicate corresponding parts in all views, and in which:

FIGURE 1 is a side elevational viewV of my invention.

FIGURE 2 is a transverse sectional view taken on the line 2-2 in FIGURE 1; while FIGURE 3 is another transverse sectional view; and

FIGURE 4 is a transverse sectional View taken on the line `4 4 of FIGURE 3.

Referring more particularly to the drawing, the numeral indicates a cervical collar consisting of two parts or sections, an upper section 11 and a lower section 12, while an elongation of the lower section constitutes substantially the neck-portion of the collar, when this is in closed or tied position.

Two sheets of a soft but durable material 13 and 14 are folded upon themselves and each embrace a padded inlay 40, for instance, of foam rubber, thereby consti- `tuting cushioning parts above and below said collar in forming parts of same.

The folded material 13 is identified by the upper section 11; said material is folded upon itself, having a soft inlay 40 and a plastic stabilizing strip 16 embedded therein; while a leather strip 18 is stitched to said material as at 17.

A like construction applies to the other piece of material 14, identified by the lower section 12; this material has also a soft inlay 40 and a plastic stabilizing strip 16 embedded therein; while a leather strip 18 is stitched to said material as at 19.

An elongation 15 of the lower section 12, especially in the form of the leather strip 18', makes the neck-portion 15 to which buckles 20 are attached for securing the collar to the neck of a person.

Through air-vents 42 are formed in both sections.

For sidewise movement or self-'adjustment of the collar, rivets 22 are secured upon each side of the surface of the section 11, and accommodated by slots 23 in the section 1'2.

A flat metal bar 24 is ixedly secured to the section 11 Patented Aug. 21, 1962 by rivets 25, only one of which may be seen in FIGURE l, or in said section.

A flat metal plate 26 is secured by screws 27 upon the front surface of the section 12, the latter has upon its rear surface, opposite the metal plate 26, a member or washer 28 fixedly attached to said section; another metal plate 29, of substantially same size as the metal plate 26, is loosely arranged behind the section 12, but engaged by the aforesaid screws 27 for co-operation with the metal plate 26; said metal plate 29 is at its center countersunk as at 30 whereby to slidably receive therein the flat bar 24 during the adjustment up and down of the two sections 11 and 12.

The said adjustment is `done by slightly loosening the screws 27, whereby, when t-he desired height of the combined sections 11 and 12 relatively is obtained, said screws 27 are again tightened, and the at bar 24 will then, due to the countersunk confinement, and its friction with the member Washer 28, remain rigidly in place, thereby preventing any wabbling of the sections 11 and 12.

It is obvious that changes maybe made in the arrangement and construction of the several parts shown and described herein, without departing from the spirit of this invention, and I do not, therefore, wish to confine myself to the exact description herein.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is:

=I claim:

1. A cervical collar comprising lan upper anda lower section, each section consisting of a suitable material folded upon itself, a soft inlay and a plastic strip embodied within said material and a leather strip stitched to the latter, air vents through said sections, and means for adjusting the height of the collar, said means comprising a substantially at bar secured to the upper section, two metal plates arranged one upon each side of the lower section with one of said plates being adapted t-o slidably receive said bar, screws adjustably seeming said plates together, and a washer embodied in the wall of the lower section below the plate upon the outer side for friction engagement with the bar in adjusting the latter.

2. rThe invention as claimed in claim l, and wherein said washer disposed in the wall of the section frictionally engages said bar, the lower plate in said section being formed with a countersunk portion adapted to slidably recive said bar in the adjustment of the height of the col ar.

3. The invention as claimed in claim 1, and wherein said bar is secured/to the upper section by screws near its upper and lower ends, the lower one of said screws limiting the downward movement of said bar, lsaid washer be' ing,` mounted within the wall of the lower section and s beneath the outer plate and adapted for frictional engagement with said bar in adjusting the height of the latter relative to the sections.

4. The invention as claimed in claim 1, and wherein the lower section substantially forms the neck-portion of said collar.
