Abstract: A jaw exercising device which includes an outer frame having spaced apart cross members and an inner frame with spaced apart cross members coupled to the outer frame for movement therealong and outwardly extending blades for engaging the jaws of a patient carried by adjacent cross members of the outer and inner frame.
Abstract: An exercising apparatus. The exercise apparatus includes an outer frame having curved first and second rails and an outer handle between the rails, and an inner frame slidably coupled to the outer frame for movement of the inner frame along the first and second rails. The inner frame includes an inner handle movable toward the outer handle when the inner frame is moved in a first direction. The apparatus also includes at least one resistance device coupling the inner and outer frames together, the resistance device resisting movement of the inner frame in the first direction.
Abstract: An exercising apparatus and method for exercising the hands and forearms. The apparatus includes an outer frame having spaced first and second outer handles, and an inner frame coupled to the outer frame for reciprocal movement between the outer handles and having first and second inner handles. The first outer handle and first inner handle define a first gripping member, and the second outer handle and second inner handle define a second gripping member. The gripping members are each engageable by a hand for selectively moving the inner handle toward the outer handle and resisting movement of the inner handle away from the outer handle. The method includes the steps of providing an exerciser, grasping the first outer handle and the first inner handle with a first hand and the second outer handle and the second inner handle with a second hand, and moving the inner frame between the outer handles.
Abstract: A hand exercising apparatus for strengthening the hand and forearm muscles and improving joint mobility while protecting the skin of a hand using the apparatus is disclosed. The apparatus includes an outer frame having an outer crossbar and an outer grip bar transversely mounted between two parallel rods. An inner frame is slidably mounted in the outer frame and has an inner crossbar and an inner grip bar parallel and adjacent to the outer crossbar and the outer grip bar. A coupling assembly connects the outer crossbar to the inner crossbar and provides a resisting force as the inner frame is moved along the outer frame. An altering device increases and decreases the distance over which the inner frame may be moved along the outer frame. An inner cushion sleeve is mounted on the inner grip bar, while an outer cushion sleeve having an area of reduced thickness for receiving the second crossbar is mounted on the outer grip bar.
Abstract: Disclosed is a multi-faceted light reflector and a method of manufacturing the reflector. Planar facets are arranged in tiers, or in some other order, tangent to the surface of a spheroid to form the reflector. The size and location of the facets are correlated to the size and location of the illuminated plane. A light source is located at one focus and the illuminated plane is located at the other focus where the illuminated plane is perpendicular to the major axis of the spheroid. The facets are dimensioned and positioned so that substantially all of the reflected light from the light source is reflected to a preselected area on the illuminated plane. The method of manufacture includes calculating the coordinates for each facet, forming a convex die from the calculated coordinates, and molding the concave reflector from the convex die thus formed.
