摘要:
A line casting apparatus including a line traversing cam encircling an open-ended spool. A hand crank and gear train drive the spool and the line cam to rotate them at a different rate relative to each other. This produces a high number of even-wound turns of line, per layer, upon the spool and results in a very orderly peeling of the line during a cast. A motor is drivingly connected to the spool to rotate the same during the cast so that centrifugal force overcomes line peel resistance to result in casts of greater distance. Upon rotation of the hand crank, a nonspinning bail is smoothly and automatically tripped to pivot to a line retrieval position for line pick-up and winding. The nonspinning bail holds the line within reach of the index finger of the hand normally holding the casting apparatus. During winding, a clutch connects the spool with the gear train, line traversing cam, and hand crank. A trigger, which controls the clutch and the motor, is positioned for convenient operation with the mentioned index finger.

A portable heating system operable in three modes; an under-blanket heating mode, a tent heating mode, and a food heating mode. In the under-blanket heating mode, one or more users cover themselves and the basic heater (2) with a light foil-type blanket (68). Air, warmed by the heater, spreads under the blanket thereby enveloping the users so that they are comfortably warm. An adjustable canopy frame (40), in concert with a heat guard (4) enclosing a heat source (6), promotes gaseous circulation under the blanket without hazard. A thermostat (17) automatically maintains the temperature at a safe level. In a tent heating mode, the invention includes an exhaust guide for guiding combustion gases to the outside of a tent via the tent entry. Means are provided for drawing air from outside the tent into the heater for supporting combustion. Means are also provided for the system to adapt to rough or uneven terrain for high stability. In a food heating mode, the mentioned heat guard is positioned above the heat source. In this alternative position, the heat guard receives a cover (71) wherein the combination serves as an oven for heating food.

An interdental cleaning and polishing tool comprising a housing and a pair of tines pivotally supported on the housing wherein the tines receive teeth to be cleaned therebetween. Each tine having guides for guiding the transfer of dental floss from one tine to the other tine wherein the floss forms a movable span therebetween. A dispensing spool dispenses floss to one tine while a take-up spool retrieves floss from the other tine. Means are provided for oscillating the tines up and down relative to the teeth and for simultaneously producing continuous slow rotation of the take-up spool. Stationary shield tines individually enclose the oscillating tines to prevent the latter from contacting oral tissues. Means are provided for locking and unlocking the floss span so that when locked the span is immovably taut so that the same can be forced through tight spaces between adjacent teeth. Means are also provided to allow the span to yieldingly slacken if applied to oral tissues with greater than a predetermined amount of force, thereby protecting soft tissues. The tool is loaded with a covered floss dispensing spool which inhibits floss contamination. Used floss is level-wound on the take-up spool. The oral portion of the instrument is designed so that the shield tines, as well as the movable tines, can be cleaned by rinsing under hot running tap water without having to remove parts.

A cap lamp (5) includes a baseball-style cap (6) having a visor (16) with an underside substantially defined by a concave visor reflector (22). A light source (24) is pivotally supported under the visor for directing light at selectively adjustable angles. A first hood (36A) partially surrounds the light source for shading a user's face from light coming directly from the light source. The hood has an upward lateral opening (39) to emit light toward the visor reflector for flooding the immediate vicinity of the user with visor reflected light. A frontal opening (42) of the hood is provided for emitting a light beam forward of the visor. A concave hood reflector (40), within the hood, is provided for increasing the light directed to and reflected by the visor reflector. A second hood (36B) is supported to rotate about the first hood between open and closed positions for selectively inhibiting light communication with the visor reflector. An arcuate strip (49) is hidden within the cap to support a battery holder (54) which is electrically connected to the light source for energizing the same.

A bite device for dental flossers having a fork which supports a floss span between tines of the fork. The bite device includes a bite member (10) having a bite surface (21) on one side and a stop guard (24) on an opposite side. The bite member is movably supported between the fork tines such that the member and the fork can move up and down relative to each other. The member is connected to the fork such that a user biting on the bite surface can drive the floss span through a tight interdental gap wherein the stop guard engages a user tooth adjacent the floss span to prevent over-travel of the span thereby preventing floss impact against user gums. When the bite is released, the bite member moves to a neutral position to allow a full range of flossing motion.
摘要:
An automated dental flosser (10) comprises a pair of pivotally supported tines (18) which support a movable floss span (17). A pair of rotatably supported subcapstans (38, 40) are floss-connected to each end of the floss span, respectively, and are alternately driven to reciprocate the span longitudinally. A floss dispensing spool (50) and a floss take-up spool (56), floss-connected to respective subcapstans, dispense and take up floss. A floss-engaging portion of each subcapstan differs from the other in diameter to result in a net transfer of the floss from one spool to the other. Means for reciprocating the tines moves the span up and down. A pair of stationary shield tines (16) shield the user's teeth from the reciprocating tines. A second embodiment (90) includes an astable pulse generator (106) that generates a train of pulses of alternately reversing electric charge. Pulses of one charge are of longer duration than those of the other charge. A reversible DC motor (104) is drivingly connected to floss dispensing and take-up spools (98, 100) which are floss-connected to each end, respectively, of a tine supported floss span (96). The motor, energized by the alternating pulses, alternately reverses direction to reciprocate the floss span. A net transfer of floss from one spool to the other results from the longer pulses. A third embodiment (116) includes two ultrasonic transducers (127, 128) connected to floss-supporting tines (118). The transducers are mounted at right angles to each other for reciprocating the tines and floss span up and down and side to side.

A flosser includes a frame (2) having a pair of tines (42) mounted on it for supporting a span of floss (62). At least one of pair the tines is pivotally supported for moving toward and away from the other of the pair of tines. Gear-driven capstans (24, 26) are provided for reciprocating the span of floss longitudinally between the tines, while a cam (9) and cam follower (11) act on a lever (32) for reciprocating the tines vertically. A spring (48) urges the tines to move laterally apart to an open position. Each of a pair of engaged sector gears (46) is fixed to a respective tine so that lateral movement of the tines is symmetrical. The spring is adjustable so that when the moving floss span encounters tooth resistance, floss tension increases to overcome the spring force and move the tines toward a closed position. The bulbs (50), which contain rollers (54), are mounted to swivel so the floss span can move in any direction. Thus, the span can wrap around a tooth and reciprocate laterally and vertically thereabout.
