Abstract: An ergonomic pillow includes a body having a top with upper, middle, and lower stepped portions descending from the rear to the front thereof, and a transverse, elongated support member arranged between the upper and middle stepped portions. The pillow is usable for supporting a supine person for sleeping, so that the head is supported on the upper stepped portion, the neck is supported on the elongated support member, the shoulders are supported on the middle and lower stepped portions. Thus the head is tilted back slightly relative to the back, so as to promote shortening and relaxation of the muscles on the back of the neck and shoulders. The pillow is also usable for supporting a person sleeping sideways, so that a shoulder is supported on the middle and lower stepped portions, and the head is supported on the elongated support member in a comfortable, natural position.

Abstract: A clothesline device includes two spaced apart arms that support several clotheslines therebetween for hanging laundry. Thumb-head bolts removably attach the arms to mounting plates which are permanently attached to the bed platform of a camper vehicle. The clothesline device is attached to the outside of the camper, so that the arms can be mounted far enough apart for supporting long clotheslines, which can be used for hanging a large number of garments. The supporting arms can be easily removed from the bed platform for storage by unscrewing the thumb-head bolts.

Abstract: A pin unseating tool is adapted for unseating tapered pins firmly seated in tapered sockets. The tool includes a shank having one end removably attached to an adapter. The adapter has a threaded hole for screwing onto any tapered pin having a threaded tip that extends out of the socket. Mounting an air impact hammer to the other end of the shank and applying a repeating pounding force along the axis of the tool will quickly and effortlessly unseat the pin. The adapter is securely screwed onto the pin, so that it will not bounce off during the procedure, or damage the thread thereon. The adapter is removable from the shank, so that other adapters with different size holes can be fitted onto the shank for unseating pins of different sizes.

Abstract: An ergonomic computer mouse includes an upright, primary finger-supporting surface for supporting all of the fingers of an upright hand in straight positions and in an upright stack. It also includes an opposite thumb-supporting surface for supporting the thumb. A hand holding the ergonomic computer mouse will be in a naturally upright and relaxed position, without requiring twisting of the hand, wrist, or forearm. As a result, fatigue, discomfort, and pain are minimized or eliminated even after a long period of continuous use.

Abstract: A scalpel includes a circular blade rotatably attached to one end of a handle. A circular depth guard having a diameter smaller than that of the blade is rigidly and coaxially connected thereto. The depth guard includes tractional knurls arranged around a rim thereof. Pressing the blade into a piece of tissue causes penetration thereinto until the depth guard engages the tissue. Pulling the scalpel along the tissue causes the depth guard to roll along thereon and rotate the blade, which makes a cut with a rolling motion that minimizes tissue adhesion and dragging for a smooth and even incision. The depth guard ensures that the blade cuts at a precisely known and perfectly even depth. The tractional knurls ensure reliable rotation of the depth guard and the blade even on wet and slippery tissue. In a second embodiment, a rotary depth guard is attached to a fixed blade. In both a third and a fourth embodiment, a circular rotary blade and a circular rotary depth guard are eccentrically mounted.

Abstract: A wall corner finishing tool includes a pair of plastic blades connected by a living hinge. The proximal ends of a pair of arcuate arms are hingeably connected to the back sides of the blades. The arms are curved toward each other so as to overlap at their intersection. The arms include longitudinal openings extending therethrough. A handle is attached to the intersection of the arms by a screw extended through the openings and into one end of the handle. When the screw is loosened, the arms can be moved toward or away from each other to adjust the angle between the blades. When the blades are positioned at a desired angle, the screw can be tightened to fix them in position. The blades can be adjusted for finishing wall corners of a great variety of angles.

Abstract: A dustless sanding device includes a base with a hollow chamber and a top opening. Bottom and side inlets communicating with the chamber are arranged on a bottom and sides, respectively, of the base. A pair of spaced apart hollow brackets extend upwardly from a rotating member rotatably positioned within the top opening, and communicate with the chamber through the rotating member. A T-shaped hollow air connector has a transverse portion rotatably positioned between the brackets and in communication therewith. A pair of Wing Nuts at the ends of the base secure a porous sanding screen wrapped around the bottom of the base. A vacuum cleaner can be attached to the air connector for extracting sanding dust produced during the sanding process through the sanding screen.

Abstract: A surgical instrument cleaner includes a containment chamber with an intake opening on a front thereof and an exhaust vent on a rear thereof. A manifold is positioned in the intake opening, and connected to a steam source. Nozzles arranged around the manifold emit converging steam jets at a single point positioned away from a plane defined by the nozzles. The steam jets are directed rearwardly into the containment chamber, so that they create a front-to-rear airflow between the intake and the exhaust vent. An instrument is positionable at the jet convergence point for cleaning. The airflow carries steam and airborne debris blasted from the instrument safely away from the user.

Abstract: A bicycle chain lubricating device includes a housing (10) with an elongated channel (17) extending therethrough, and a lubricant hole (16) extending between an exterior surface of the housing and the channel. A set of brushes (19) are mounted within the channel. The housing is separable into upper and lower housings (11, 12) along the channel for receiving a portion of a bicycle chain (30) therebetween. An anchoring hook (24) extending from the housing anchors it to the bicycle. In use, the chain is moved through the channel by cranking the pedals backwardly, and a lubricant (32) is introduced into the lubricant hole. As the chain is moved through the channel, the brushes distribute the lubricant along the chain. Because all the lubricant is efficiently directed at the chain, only a minimal amount of lubricant is needed. The housing confines the lubricant therein to keep the bicycle and the surrounding area clean.
