摘要： An earplug for blocking sound and method of making the same, which includes a planar insert within an earplug of compressible slow recovery foam. A method of attenuating sound by inserting the earplug at an ear canal entry so that the planar insert is tactilely vertical, and pushing the earplug into the ear canal allowing the earplug to flex perpendicular to plana surfaces of the planar insert.

摘要： A noise blocking band earplug has a band (12) with outer portions (44, 46) that are bent to prevent the ear-engaging pods (20, 22) from touching the ground, whether placed right-side-up or upside-down on the ground. When the middle region (32) of the band rests on a horizontal surface (64), a band inner end part (70) extends at an upward incline (C) with its outer end forming a second bend (80) so the outer end part (72) extends at a downward incline (D), with the second bend preventing the pods from touching the ground when the earplug is laid upside-down. At the second bend (80), the largely vertical height (J) of the band is increased and its outer surface (102) is made convex to provide pods for more readily pressing the pods against the outside of the ear canals.

摘要： An earplug of the slow recovery type is described, which has open cells for expelling gas to the outside during compression, but which resists the entry of water through the outside and the soiling of the outside by dirt. The earplug includes a body formed of pressure-molded slow recovery resilient foam material forming multiple gas-filled shells. The plug body has a surface region forming a skin wherein the average cell cross-sectional area is less than half that of cells at the center of the body, and is less than one-tenth millimeter, the surface region being primarily continuous.

摘要： An ear protector assembly which can be mounted on a protective helmet, including a mount which can be attached to the side of the helmet, a linkage pivotally connected to the mount, and an earplug mounted on an end of the linkage. The linkage includes a pair of pivotally mounted bars that enable adjustment of the earplug position into alignment with the ear canal of the wearer, while resisting outward deflection so the earplug can be pressed against the ear canal. The linkage can be resiliently deflected outwardly so the earplug can move around the rim of the helmet and rest upon the rim for stowage out of the way of the wearer.

摘要： An earplug for blocking sound can be installed uniformly deep in a person's ear canal and can be easily withdrawn. The earplug includes a foam cylinder (12) and a string (14) extending in a loop from the rear of the cylinder, with opposite front ends (32, 34) of the string loop projecting into the body and held therein as by adhesive (38).

摘要： A compact exercise device (10) of the type wherein a person grips handle devices (12, 30) lying at opposite ends of a rope that extends through a housing (22), the person pulling one end of the rope away from the housing while resisting movement of the other end of the rope towards the housing to exercise. A windup spool (114) lies in one of the handle devices and a spring (130) urges the spool to wind up rope by a spring, but the spool is normally prevented from turning in either direction by a release mechanism (110). A person who holds a handle grip (100) with most fingers of his/her hand, uses his/her thumb to depress a button (90) to operate the release mechanism. While the thumb continues to depress the button, the person moves a handle device away from the housing to lengthen the effective length of rope, or moves a handle device towards the housing to shorten the effective length of rope. In another device, windup spools (226, 228) lie in the housing, and a person depresses a button (202) on the housing to operate the release mechanism.

摘要： A noise blocking earmuff is described, which has a better noise blocking ability and which is more comfortable than prior earmuffs. The earmuff includes a cup-shaped shell (20), a cushion (22) that surrounds the open inner end of the shell and which presses against the head of the wearer, and an inside sound-absorber (26) lying in the shell. The cushion is formed of slow recovery material which has a rebound of no more than about 10 percent, to more comfortably and completely conform the cushion to the area of the wearer's head that the cushion presses against. The inside sound absorber includes a layer (50) of resilient felted foam for blocking higher frequency sounds, and a layer (52) of unfelted foam for blocking lower frequency sounds, to obtain a better overall noise blocking capability.

摘要： An elongated earplug of slow recovery material has one end portion (14) for use in large ear canals to effectively block noise therein and an opposite end portion (16) for use in small diameter ear canals to block noise while maintaining a moderate comfort level for the wearer. The opposite end portions of the earplug are of different colors, to enable a person picking up the earplug to quickly determine which end to place in the ear as well as to identify the earplug as a dual type. The larger end is preferably of a lighter color such as yellow, then the darker end which is of a darker color such as medium to dark green or orange, to emphasize the largeness of the large end and the smallness of the small end. One dual earplug has a small end portion which is tapered along most of its length, at an included tapered angle (B) of about 15.degree., with the end portion progressively increasing in diameter until merges with the large end, without a step in diameters thereat, which facilitates rolling of slow recovery material in the fingers prior to insertion.
