  • Patent number: 5464010
    Abstract: A respirator 15 has a harness 10 that allows the respirator body 20 to be conveniently disposed beneath a wearer's chin when not in use. The harness 10 includes a substantially flat, flexible strap 14 and an element 12 that contains a curved elongated slot 16. The substantially flat, flexible strap 14 is threaded through the curved elongated slot 16. The curved configuration of the slot 16 causes the flat flexible strap 14 to be deformed to assume the curved configuration of the slot. This deformation of the strap 14 allows the strap 14 to frictionally engage element 12, and the frictional engagement allows the respirator body 20 to be incrementally withdrawn from the wearer's face so that it can be temporarily stored beneath the wearer's chin, and allows the respirator body 20 to be conveniently repositioned over the nose and mouth of the wearer by simply pulling on free ends 34 of each strap 14 and joining a buckle 32 behind the wearer's neck.

  • Patent number: 5425701
    Abstract: An orthopedic brace to facilitate healing of injuries to the foot, ankle or portions of the leg above the ankle includes a boot having a lower edge section releasably connected to a sole. The width of the boot, as well as the distance between a pair of upright struts located along opposite sides of the boot, may be varied to complementally match the width of the patient's foot. The struts and a section of fastening straps are located between layers of foam pads of the boot to reduce the likelihood that the straps or struts will become ensnarled with other items. The sole has a mirror image configuration on either side of its longitudinal axis, and left and right insoles are provided so that a single boot may be used with either the left or right foot of the patient.
