    摘要： A safety cover for foot valves has a base plate for supporting a valve body and a foot pedal cover portion including a front wall and laterally opposed side walls extending upwardly from the base plate and a top wall extending between upper ends thereof. The front wall has an aperture through which the foot lever of the valve extends and laterally opposed side extensions having a vertical portion extending outward from respective lateral sides of the front wall and a forwardly extending horizontal top portion at the upper end thereof spaced a distance above the base plate. A valve body having a fluid inlet, a fluid outlet, and a valve element therein connected with a foot lever extending outwardly from the body is secured into the base plate with its foot lever extending through the aperture in the front wall of the cover. The front, top and side walls of the cover partially surround the foot receiving portion of the foot lever and protect the foot of the operator from injury in the event of a failure. The laterally opposed side extensions partially surround hose and lance fittings that are connected with and extend outwardly from the valve body and protect the upper body of the operator from injury in the event of a failure, and also protect the fittings from damage by the foot of the operator.

    摘要： A foot control mechanism for a dental apparatus has a tiltable actuation member mounted on a base part and an arrangement for holding the tiltable actuation member in a neutral position, which requires sufficient force to move the actuation member in either direction from the neutral position to a switch position. To accomplish this, the structure includes a mounting arrangement utilizing a pair of spaced-apart bearings extending parallel to each other which bearings receive projections on the other element and, preferably, a catch member is provided which provides a resistant force from movement from the neutral position.

    摘要： A foot pedal comprised of a single molded body having an integral connecting flex member extending downwardly therefrom which is capable of being attached to a mounting. Upon an application of force to the pedal to operate an external member connected thereto, the flex member is temporarily placed under stress and flexes concavely towards the horizontal, the pedal automatically returning to its normal resting position upon a removal of the applied force.
