9 Claims. (Cl. 12821) This invention relates to improvements in instrument supporting head bands. v v
The general object of the invention is to provide an instrument supporting head band having improved characteristics of ease and certainty of adjustment. j
With this and still other objects which will appear in the following full description in mind, the invention consists in the combinations and arrangements of parts, and details ,of construction, which will now first be fully described with reference to the accompanying drawing and then be more particularly pointed out' in' the appended claims.
In the drawing:
Figure 1 is a plan view of a head band embodying the invention in a preferred form;
Figure 2 is a side elevation;
Figure 3 is an exploded view on an enlarged. scale of part of Figure l, with parts broken away to show internal structure;
Figure 4 is a view similar to Figure 3, but showing the parts assembled;
Figure 5 is an enlarged section on the line 5 -5 of Figure 2;
Figure 5A is a detail plan view of a clip element of Figure 5;
Figure S-B is a section on the line 5B5-B of Figure S-A; and
Figure 6 is an enlarged view of a portion of Figure 2, with parts broken away to show the structure.
The head band includes a pair of straps 1 and 2 forming a head band, together with a forehead fitting, indicated generally at 3, for adjustably supporting a mirror, light or other desired piece of equipment. A typical use of such device is by physicians, wherever illumination of an area being examined is required. Strap 1 may be provided with perforations 4, as usual, and has a series of sets of triple perforations 5 for holding a locking device generally of usual type. This device comprises a circular disc 6 having a threaded center stem 7 and a pair of prongs 8, the stem 7 and prongs 8 being accommodated in a set of the holes 5, as indicated in Figures 5 and 6. An apertured plate 9 and knurled nut 10 complete the fitting. The other strap 2 has a slot 11 within which the prongs 8 and stem 7 fit, and the head band may be adjusted by sliding the strap 2 to desired position and then tightening the nut 10. To provide for extreme ranges of adjustment, the member 6 may be shifted from one set of holes 5 to another. The diameter of the holes 5 is preferably such that the prongs 8 fit snugly, so that there is no tendency for the element 6 to fall out when the nut 10 is loosened, and so that the tendency to open a gap between the disc 6 and the strap 1 in which the hair might be caught is eliminated. Since the disc 6 may be shifted for major adjustments, the slot 11 may be made much shorter than usual with similar adjustments, reducing tendency of the slot edges to gap. As shown in Figures S-A and 5B, the disc 6 has a slightly raised rim 6' forming a center concavity, preferably just large enough to receive the nut 10. This results in the frictional grip occurring between the inner edge of the rim of disc 6 and the outer edge of nut 10, permitting the parts to bite into the strap 2 and removing the pressure area from the edges of the slot 11. It is found possible, with this construction, to eliminate the plate 9 and a much better holding action is obtained, with or without the plate, than can be had where the disc 6 is flat.
The other ends of the straps 1 and 2 meet and overlap over the forehead, these straps having holes 15 (Figures 3 and 4) for fitting over a stud 16. The stud 16 carries a ball 17 and is formed with a flange for engaging a cupped cover disc 18. A cushion 19 automatically fits and conforms to the forehead. The cushion 19 is preferably circular and concave, as shown, and is preferably made of rubber, synthetic rubberor similar resilient material.
An insert 20 having upset perforations 21, for preventing" its turning and coming loose, is molded in the disc 19,
and the splined or ridged end 22 of the stud 16 is driven into a tubular central portion of the member 20 so as to be held securely therein. A slight boss 23 is formed in the center of the element 19. Driving the stud 16 brings the parts into the relation shown in Figure 4, where they are securely held together but pivotal movement of the' straps 1 and 2 is permitted about stud 16.
The pivotal attachment of the straps 1 and 2 at the forehead fitting permits angular adjustment of the straps to conform to and lie flat against the forehead adjacent the temples. The cover plate 18 compresses the straps against the pad or cushion 19 toward its center to retain 1 the straps in a given angular adjustment. With the headround, as shown, so as to operate in any position.
. should conform to the cushion 19 in the vertical plane,
band in position on the head, the straps compress the pad almost to its edges, further restricting pivoting of the straps about stud 16. The cover disc 18 is preferably It to the extent that its edges will engage the pad, when it is attempted to rock the stud 16 downwardly, thus holding the stud and instrument supported thereby in position.
Ball 17 serves as a universal support for a mirror or other device, fitting in one end of a supporting clamp 24.
The supporting clamp comprises two halves 25 and 26, fastened together under adjustable pressure by thumb screw 27 received in the threaded opening 28 of the member 26. The members 25 and 26 are strips of stiff spring sheet metal and are cupped and apertured at each end as indicated, for receiving and holding the ball 17 and a similar ball 30. The stem 31 of the latter supports a mirror 32 or other desired device.
Each of the strips 25 and 26 is formed as a channel having stiifening flanges 35 of roughly parabolic profile. The elements 25 and 26 are made of stiff and springy stainless steel and by reason of their channel cross section are substantially rigid except at their ends where sufiicient spring for gripping the balls 17 and 3t) isprovided. The clamp may be turned through any desired angle and the mirror 32 or other device may be turned at any desired angle to the clamp.
A spring 40 may be provided for holding the elements 25 and 26 apart when loosening up the screw 27 for inserting or removing the ball 17 or 30.
The concave sockets in which the balls 17 and 30 are held are carried out to the extreme ends of the elements 25 and 26, and the socket subtend an angle of only about 60, leaving substantially of arc through which the clamp or mirror may be swung in the plane of Figure 4, even after allowing for the thickness of the stem, in addition to or more swing permitted at right angles to this plane. Substantially complete freedom of movement in all directions is thus insured.
What is claimed is:
1. An instrument supporting head band comprising a pair of straps, means adjustably joining the straps together at one end thereof, a forehead fitting comprising a sup port adapted to lie fiat against the forehead and substantially wider than the straps, and means pivotally attaching the other ends of the straps to the forehead. fitting.
2. An instrument supporting head, band. comprising a pair of straps, means adjustably joining the straps together at one end thereof, each of the straps having an aperture in its other end, and a forehead fitting comprising a pad and a stud passing through the strap apertures'for pivotally attaching the straps to the forehead fitting.
3. A head band according to claim 2, in which the forehead fitting comprises a resilient pad and a cover plate carried by the stud, the straps being positioned between the pad and cover plate for compressing the pad against the forehead upon application of tension to the straps.
4. A head band according to claim 3, in which the upper and lower edges of the cover plate are positioned for engaging against the pad to prevent tilting of the stud in a vertical plane, when the lead band. is in position on the head.
5.

6. A head band according to claim 5, in which theplurality of apertures include a plurality of spaced sets of three apertures adapted to take the clip.
7. In an instrument supporting head band and in combination, a resilient forehead pad, a stud fixed in the resilient pad and passing through the head band, a cover plate conforming to the forehead pad and held thereon by the stud, a ball on the outer end of the stud and a clamp gripping the ball for mounting an instrument thereon, the
1 boring apertures, the disc having a depressed central area surrounding the stem, and cooperating clamping means comprising a nut carried on the stem between the projections for compressing the straps together.
9. A head band according to claim 8, in which the nut is of slightly less diameter than the depressed area of the disc.
