Definitions
- This invention relates to improvements in a suspension for a pair of noise suppressing ear cups or car muffs. More particularly, it relates to a means for anchoring the end loops of a headband to enable the headband to be easily attached to or detached from the base plates of the ear cups.
- An object of the present invention is to provide a novel nape type suspension and anchoring means for suspending, in a detachable manner, a pair of ear cups for suppressing noises.
- a further object of the invention is to provide a unique slot design in the base plates of the ear cups which enable easy insertion and attachment, as well as easy withdrawal and detachment, of the end loops of an adjustable headband which fits either across the top of the head or about the nape of the neck or beneath the chin of the wearer.
- FIG. 1 is a perspective view of a pair of noise suppressing ear cups having a suspension embodying the present invention
- FIG. 2 is a side view of one of the cups shown partly broken away and in cross-section;
- FIG. 3 is a plan view of one of the ear cups showing the slotted base plate thereof.
- FIG. 4 is a fragmentary, perspective view of an end portion of the headband 7.
- numeral 1 generally denotes a noise suppressing ear cup or ear muff assembly
- a noise suppressing ear cup or ear muff assembly comprising a pair of ear cups 2 of rigid material, such as plastic or metal, which car cups are provided with oval ring shaped base plates 8 which are preferably slightly tapered in the direction of the opening therethrough, as shown more clearly in FIG. 2, having an angle of about 6 to 9.
- Supported on the base plates 8 is a tubular ring for cushion of flexible material, such as rubber or plastic material filled with a fluid, such as a liquid or semi-solid pliable or fiowable material, such as a grease, or with foam.
- base plate 8 is slotted for providing an anchor for the end loops 11 of the flexible strap or head nited States Patent O band 7.
- a T-slot is provided comprising a horizontal slot portion 10 and a vertical slot portion 9, into the latter of which the folded end portion 11 of the headband 7 is inserted and then opened in the manner shown in FIG. 2 so that a portion of the end loop 11 enters slot portion 10 and exits immediately below slot portion 9, contacting the inner edge opening of base plate 8, as shown.
- each of the end loops 11 of the headband 7 may be easily and quickly anchored to its corresponding base plate or removed therefrom when it is necessary to replace the headband or perhaps the cups.
- the length of the headband is adjusted by buckles 12.
- a telephone headrest type of band comprising a flexible but somewhat rigid tube 3 of arcuate shape into which a strip portion isadapted to adjustably slide, in a well known manner to change the effective arcuate length, and terminating in adjustably rotatable adjusting means 4 for adjusting the clamping pressure of the ear cups as shown in more detail in US. Pat. No. 3,457,565.
- the tube 3 is in a plane substantially at right angles to that of headband 7 and serves as a nape strap in the assembly shown in FIG. 1.
- the ear cups 2 would be rotated from the position shown, whereby the adjusting means 4 would be located at the top ends of the cups as presently viewed in FIG. 1.
- ear cups 2 are preferably coated with a highly polished, mirror-like metallic coating 2a, such as an aluminized or silver coating which may be sprayed onto the cups and thus reflect away radian energy and thereby prevent overheating of the head strap 7, ring 8 and the interior parts of the cup 2.
- a highly polished, mirror-like metallic coating 2a such as an aluminized or silver coating which may be sprayed onto the cups and thus reflect away radian energy and thereby prevent overheating of the head strap 7, ring 8 and the interior parts of the cup 2.
- a headband suspension for suppressing noise comprising a pair of rigid plastic ear cups, each including a ring-like base plate supported on the mouth portion of said cup, a T-slot formed in each base plate formed so that the vertical portion of the T communicates directly with the interior opening of said ring-like base plate, and a headband including end loops inserted in said T slots so that one band portion of each end loop is disposed within the horizontal portion of the T slot and another band portion is disposed immediately below the vertical portion of the T slot engaging an edge portion of the interior opening of the ring-like base plate.
- a headband assembly as recited in claim 1 including a telephone head set type band in a plane substantially at right angles to that of said headband and having ends adjustably secured to the side of said cups so as to fit about the nape of the wearers neck.
- a susepnsion as recited in claim 1 including a heat reflective metallic coating on the outer surface of said cups for reflecting away radiant energy and for maintaining the interior of the cups relatively cool and comfortable to wear.
