Abstract: A handle configured to be mounted on a pole (e.g., of an IV stand). The handle includes a handle grip having first and second ends with a central section therebetween. The central section is lower than the first and second ends. The handle grip is configured to be gripped by a user at a location between the central section and one of the first and second ends. The handle grip may include first and second sections that each extend upwardly from a central section. The first section is configured to be gripped at a natural grip angle by the user's a right hand and the second section is configured to be gripped at the natural grip angle by the user's a left hand. The handle may include a connector portion configured to be mounted to the pole and connected to the handle grip.

Abstract: A base having legs supported on wheels. A second leg may be positioned between first and third legs and the first leg may be positioned between the second leg and a fourth leg. A first gap is positioned between the second and third legs, and a second gap is positioned between the fourth and first legs. The first and second gaps are configured to at least partially receive a user's first and second feet, respectively. A keyway with a bridge may be defined between the first and second legs. A key that may be formed in a fifth leg is removably receivable inside a like keyway of a like base to thereby interlock the bases together so that they are moveable as a unit. An end portion of the key is positionable underneath a like bridge of the like keyway such that the like bridge limits upward movement of the key.

Abstract: A hook attachment for an IV stand. The attachment has hooks attached to at least one longitudinally extending portion. The hooks are configured to position bags such that their labels are each visible from the same side of the hook attachment. The hooks may include first and second hooks coupled to first and second longitudinally extending portions, respectively. The first and second hooks are configured to have first and second bags, respectively, hung therefrom. The first and second longitudinally extending portions are sufficiently spaced apart vertically to allow the labels of the first and second bags to be visible. The hooks may include front and rear hooks connected to a longitudinally extending body portion. The front and rear hooks have first and second portions, respectively, whereat front and rear bags, respectively, are positioned when hung therefrom. The first portions are below the second portions.

Abstract: A system for engagement and disengagement of carts to form a train of multiple carts. Each cart has a spring-loaded hitch that is held in a storage position when the carts are disengaged. A lever coupled to the hitch is operated to position the hitch for insertion into a receiver pocket of the next cart. A leading edge of the hitch deflects a spring-loaded lockpin. An angled guide member positions the hitch vertically within the pocket so that the lockpin comes into alignment with an aperture in the hitch. When aligned, the lockpin snaps into place and engages the aperture to lock the carts together. The close tolerance of the hitch within the pocket prevents transverse articulation of adjacent carts. Structures within the hitch and the pocket allow slight rotation in a longitudinal articulation axis about the lockpin and torsional articulation of the hitch within the pocket.

Abstract: A chest support that supports the weight of a user's torso, and more particularly an adjustable chest support that is operative to be adjusted by a user “hands free” (i.e., without the use of the hands). The angular position or tilt of the chest support may be adjusted forward and rearward relative to a seat (e.g., a seat of a chair attached to the chest support), allowing the user to bend, or tilt, his or her torso toward and away from a work area. The chest support is operative to support the torso of a user at the chest area, thereby permitting the user to perform a task while reducing the likelihood of lower back pain and body fatigue. In some embodiments, arm support assemblies may also be mounted to the chest support to effect corresponding movement of the arm support assemblies toward and away from the work area upon adjustment of the angular position or tilt of the chest support.

Abstract: A double-pole single-throw switch has a pair of spaced stationary contacts adapted for carrying current to individual circuits. A cantilevered, torsionally flexible, electrical current carrying arm has a pair of correspondingly spaced moveable contacts mounted on the free end and disposed adjacent the stationary contacts. A toggle spring actuator has one reaction end engaging a slot in the end of the electrical current carrying arm for effecting relative lost motion movement and impacting the sides of the slot for causing rapid making and breaking and a wiping motion of the contacts. The spring engages the slot midway between the contacts to permit angular movement to accommodate misalignment of the stationary contacts.

Abstract: A microswitch is mounted between the sides of a U-shaped channel bracket. The sides of the bracket are pulled together to clamp the switch therein by a screw passing through a hole in the switch body. Tabs extending from the edge of the bracket sides move the switch by camming as the sides are pulled together to cause one side of the switch mounting hole to be registered against the screw to maintain the switch securely in one position on the bracket.

Abstract: A rotary actuator for an appliance having a shaft with a radially outwardly-extending boss with a cam surface thereon locked in an "OFF" position between a stop and a detent lug. The user is required to move (push) the shaft axially in order to enable the boss to clear the detent to permit rotary movement away from the "OFF" position stop for affecting a control function. As the boss is rotated past the detent to the desired "ON" position, and upon user release, the shaft is spring biased to return to its initial axial position. Upon return rotary movement of the shaft by the user, the cam automatically moves the shaft axially to enable the boss to pass by the detent to return to the "OFF" position against the stop.

Abstract: A thermostatic switch having a snap acting switch mounted for actuation between the side walls of a U-shaped bracket. A remote bulb-and-capillary thermal sensing capsule provides output motion to a lever for switch actuation. The lever has an edge portion pivotably engaging a reaction support tab on one bracket wall and a rotatable cam provides an adjustable reaction support on the opposite bracket wall. The cam slidably engages an arcuate groove on the lever to maintain the lever transversely and longitudinally positioned on the bracket for switch actuation.

Abstract: A thermostatic switch assembly with a diaphragm responsive to pressure generated in a fluid filled temperature sensing bulb-and-capillary. The diaphragm contacts and moves a pivoted lever having a beam spring cantilevered beam spring adjustably mounted thereon. Movement of the lower about its pivot causes the beam spring to effect actuation of a switch. Upon loss of fluid in the bulb and capillary, the diaphragm recedes and a stop remote from the lower pivot functions as an auxiliary pivot for the beam spring for effecting emergency switch actuations.
