  • Patent number: 7496979
    Abstract: A vertically moveable patient table is provided with a footrest extension that may be locked in either an operative, extended position or a stowed position beneath an adjacent leg section of the table. In the stowed position the footrest extension actuates a switch which permits the table to be moved freely up and down. However, when the footrest extension is in any position other than stowed, movement of the table is restricted to prevent accidental contact of the footrest extension with a floor or other supporting surface as the table is lowered.

  • Patent number: 7491025
    Abstract: A fastener for releasably securing a first substrate to an apertured second substrate includes a base member and a locking member mounted for rotation relative to the base member. The locking member is rotatable between an insertion position for insertion of the base member and locking member through the aperture formed in the second substrate and a locking position for releasably securing the first and second substrates together. A resilient member is provided to bias the locking member toward the base member when the resilient member is compressed. The locking member includes at least one protrusion and the base member includes at least one detent. The detent and protrusion are configured to releasably engage each other in the insertion position of the locking member and disengage from each other upon rotation of the locking member toward the locking position.

  • Patent number: 7386899
    Abstract: A medical examination table has a step that is movable between a stowed position within the base of the table, to an extending position for use by persons mounting or dismounting the table. Slide members are coupled to the step inboard from the lateral sides of the step, so that the slide members are hidden from view even when the step is placed in the extended position. The step is suspended above a floor surface by the slide members and lower support members provided on a bottom side of the step, to facilitate movement of the step between the stowed and extended positions.

  • Patent number: 7137161
    Abstract: A transportation cart for relocating a medical examination chair or table comprises a chassis having an open end that defines a receiving area for positioning a base of a medical examination table therebetween. A table support member extends upwardly from the chassis to engage structural portions of the examination table, such that the table may be supported thereon when the table is lowered to rest on the table support member. With the weight of the table supported by the cart, the base may be further actuated so that it is raised from the floor. Thereafter, the transportation cart may be maneuvered to relocate the table as desired. To place the table at the new location, the base is lowered to engage the floor and raise the table from the cart.

  • Patent number: 7058998
    Abstract: A foot control for controlling power-driven functions of a medical apparatus which positions a patient in a variety of examination and treatment positions. The foot control includes a membrane switch and a flexible keypad overlying the membrane switch. The flexible keypad is configured to actuate switch elements of the membrane switch in response to selective pressure applied on the keypad by a user's foot. Different configurations of keypads are interchangeable on the foot control to change the control functionality of the foot control while the membrane switch remains unchanged.

  • Publication number: 20060038097
    Abstract: An examination table having a side rail and mounting assembly for attaching a hand control to the table. The hand control has a key-hole shaped slot in its bottom wall which receives a stud projecting from a resilient clamp engaging the table rail. The stud is loosely received in the slot, which allows the hand control to remain substantially vertically oriented as the table and rail are moved through different positions.

  • Patent number: 6984359
    Abstract: A sterilizer including a sterilization chamber for receiving articles to be sterilized and a door supported on a horizontal pivot at an access opening of the sterilizer chamber. The door includes a seal plate and a resilient seal member supported on the seal plate wherein the seal member includes an annular lip extending transversely to the plane of the seal plate. The lip extends into the sterilizer chamber wherein pressure within the chamber exerts a force biasing an opposing surface of the lip into engagement with an inner surface of the chamber. The sterilizer door is movable between a fully closed and a fully open position and includes a mechanism for holding the door in a partially open position. In the partially open position, the lip extends into contact with a surface of the sterilizer chamber to thereby form a bridge between the door and chamber and prevent condensation from dripping down away from the chamber and door.
