Abstract
Abstract A headband includes at least one tubular element having a plurality of jointed parts arranged end to end and held together by a biasing spring. The individual tubular parts are advantageously formed, for example, from a single tube which is slotted on one side sufficiently to permit articulation between the individual tubular parts which are separated by the slots. A tension spring is anchored at the respective ends to the outer ends of the outermost tubular parts so that all of the parts are urged together. The jointed portions or slots are advantageously covered by a surrounding tube of a material such as a plastic. The complete headband construction advantageously includes a transversely extending tubular part which is adapted to fit over the head of the wearer, with at least one leg portion at each end which is adapted to extend outwardly from the transversely extending part to provide means for carrying the headphones on each side thereof. In one embodiment, the outer jointed part at each end of the transversely extending headband forms a downwardly extending leg to carry the earphone of the headset. In this embodiment, the sound by the spring transmitted through a tube, and all of the jointed tubular embodiment, form a closed tube construction with the joints being covered by a surrounding tube of plastic material. The downwardly extending legs on each side of the band are advantageously biased toward each other by which holds all of the jointed parts together. In one embodiment the headphones themselves are carried in tubular members which extend telescopically into the tubular leg portions of the headband set and the telescopic part is held in position by a connecting tension spring.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
58 words
A headband construction for headphones comprising at least one tubular member having a plurality of jointed parts, spring means secured to each outermost part and holding said parts in end to end closed orientation, said parts being pivotal about their separation joints to the next associated part to open the headset against the force of said spring means.
Claim 2
Dependent Claim
58 words
A headband construction for headphones comprising at least one tubular member having a plurality of jointed parts, spring means secured to each outermost part and holding said parts in end to end closed orientation, said parts being pivotal about their separation joints to the next associated part to open the headset against the force of said spring means.
Claim 3
Dependent Claim
56 words
A headband construction for headphones, according to claim 1, wherein said headband comprises a single tube, said plurality of parts being defined by a slit extending at least partially through said tube and separating said individually jointed parts from each other, said jointed parts being pivotal about the remAining portion of the tube adjacent said slit.
Claim 4
Dependent Claim
50 words
A headband construction for headphones, according to claim 2, wherein said individual parts of said tube may open to form wedge-shaped notches at the location of said parts forming abutting end faces which are urged toward each other to close the wedge-shaped notch by the force of said spring means.
Claim 5
Dependent Claim
67 words
A headband construction for headphones, according to claim 1, wherein said headband comprises a plurality of separate tubular elements each arranged in end to end abutting relationship and having cooperating end surfaces limiting the movement of said parts together but permitting outward pivotal movement of said parts relative to each other, and a tubular member covering said tubular parts at least at the boundaries between said parts.
Claim 6
Dependent Claim
16 words
A headband construction for headphones, according to claim 1, wherein said tube has a quadrilateral cross-section.
Claim 7
Dependent Claim
42 words
A headband construction for headphones, according to claim 1, wherein said spring means comprises a helical spring which extends through the interior of said jointed parts and has respective outer ends secured to the respective outer ends of the outermost tubular parts.
Claim 8
Dependent Claim
34 words
A headband construction for headphones, according to claim 1, wherein at least one of said tubular parts comprises an outwardly extending leg portion adapted to hold an earpiece at each end of said headset.
Claim 9
Dependent Claim
51 words
A headband construction for headphones, according to claim 1, wherein at least one tubular member comprises a single tubular member including a transversely extending headband portion and outwardly extending leg portions forming earpieces at each end, said outwardly extending leg portions portions being biased toward each other by said spring means.
Claim 10
Dependent Claim
52 words
A headband construction for headphones, according to claim 8, wherein said headband comprises a closed tubular sound passage, a connecting tube connected to the transversely extending portion of said closed tubular sound passage, each of said end portions forming legs having widened portions forming earpieces which may be pressed against the ear.
Claim 11
Dependent Claim
79 words
A headband construction for headphones, according to claim 1, wherein said at least one tubular part comprises at least one closed transversely extending tubular part and a leg portion extending outwardly from each end of said closed tubular part and being pivoted to said closed tubular part, and spring means urging said leg portions into a closed position with the edges of said leg portion abutting against said closed tubular part, permitting outward pivotal movement of said leg portions.
Claim 12
Dependent Claim
85 words
A headband construction for headphones, according to claim 1, wherein said tubular member comprises a single tube having a transversely extending portion and an outwardly extending leg portion at each end, a slit extending through said tube, the connection of said leg portion thereto on one side leaving the outer side unslit and forming a pivotal joint, and spring means holding said leg portions in a closed position closing the slot, and being pivotal outwardly against said spring means to spread said leg portions apart.
Claim 13
Dependent Claim
127 words
A headset comprising a transversely extending headband formed of a hollow tube having a plurality of tubular portions formed by slots extending through said tube at spaced locations along the length thereof, a tubular leg portion telescoped with each end of said transversely extending tubes and forming earpiece mounting members, a tension spring connected to each leg portion at the interior thereof and extending to the interior of the opposite leg portion, said spring holding said leg portions to said headband transverse portion, said leg portion being oriented to extend inwardly when said spring means hold said tubular parts in a closed position, said tubular parts being movable to an open position to hold said leg in a spread apart condition against the biasing of said spring.
Claim 14
Dependent Claim
127 words
A headset comprising a transversely extending headband formed of a hollow tube having a plurality of tubular portions formed by slots extending through said tube at spaced locations along the length thereof, a tubular leg portion telescoped with each end of said transversely extending tubes and forming earpiece mounting members, a tension spring connected to each leg portion at the interior thereof and extending to the interior of the opposite leg portion, said spring holding said leg portions to said headband transverse portion, said leg portion being oriented to extend inwardly when said spring means hold said tubular parts in a closed position, said tubular parts being movable to an open position to hold said leg in a spread apart condition against the biasing of said spring.
