Abstract: A seat structure includes a substrate structure and a pad structure affixed to a top surface of the substrate structure. The seat structure has a support region configured to provide a support for a user's buttocks, and a downwardly sloped nose portion. The seat structure is bump-less in that there is no raised portion at an area between the user's legs which would extend upwardly from adjacent laterally outward portions.

Abstract: A pitching machine configured for adjustment by a user, and including a pitching head, a first macro-adjustment device and a first micro-adjustment device. The pitching head is situated atop a stand. The pitching head includes a first wheel spaced apart from an opposing surface and a first motor for driving the first wheel. The first macro-adjustment device is coupled to the pitching head and includes a first locking assembly that, when loosened, allows manual rotation of the pitching head about a first pivot axis. The first micro-adjustment device is coupled to the pitching head, and includes a first adjusting element that, when repositioned, incrementally rotates the pitching head about the first pivot axis. The first micro-adjustment device configured for operation by a single hand of a user, and the first macro-adjustment device retaining the pitching head in a secure position during adjustment of the first micro-adjustment device.

Abstract: A ball projecting machine having a C-shaped arm that provides the ability to adjust the length or elevation of pitched balls. The C-shaped arm connects a ball projecting head to a stand, with the ball projecting head affixed to one end of the C-shaped arm, and the C-shaped arm is slidably engaged through a frame atop the stand to allow rotation of the ball projecting head about a horizontal axis. A center of gravity of the ball projecting head in combination with the C-shaped arm facilitates stability of the ball projecting machine when the C-shaped arm is slid up or down. A locking device, when loosened, allows the C-shaped arm to slide up or down through the frame.

Abstract: A thin-ply roll holder, for example, a paper towel holder facilitates tearing of paper towels from a continuous roll supported on the holder, and prevents excessive unraveling of the roll. A pressure bar pivots at a hinge on the base, and is spring biased towards the pole that supports the roll, such that leverage of the bias about a hinge increases as the pressure bar pivots towards the pole, but the bias decreases at a lower rate than the increase in the leverage. At the distal free end of the pole, a retaining tab is pivoted to flip from a first orientation in which the hollow core of the paper towel is permitted to be received by the pole, to a second orientation in which the paper towel is not permitted to be removed from the pole. The pole is structured as a frame structure comprising rod-shaped segments.

Abstract: A holder for a toilet cleaning tool and an improved toilet cleaning tool has a removable drip liner within a housing. The cover of the housing pivots at the base to an opened position to provide access to allow the head of the cleaning tool to be received in the liner. The toilet cleaning tool comprises a curved handle, and a removable cleaning head. The cleaning head may be one of a brush or a sponge. A set of brushes and sponges of different shapes, sizes and configurations may be provided for interchangeably attached to the handle, depending on the intended cleaning applications. Different brushes and sponges may be impregnated with a different cleaning agent, depending on the intended cleaning applications. The handle of the toilet cleaning tool may be provided with a non-slip finish.

Abstract: A device is provided for aiding in the removal and replacement of a spa cover atop a spa tub. A pair of lifting assemblies are located on opposite sides of the spa tub. Each of the lifting assemblies includes a spring having an anchored end secured relative to the spa tub and a moveable end. Each lifting assembly employs a lifting arm mounted for rotation relative to the spa tub and including a cover-engaging end attached to the spa cover, a spring-engaging end attached to the moveable end of the spring, and a fulcrum located between the lifting arm ends. The lifting arm is rotatable between extreme covering and uncovering positions in which the spring-engaging end of the lifting arm lies on opposite sides of a straight line extending between the lifting arm axis of rotation and the anchored end of the spring. The lifting arm is rotatable through an intermediate position in which the spring-engaging end of the lifting arm passes between the fulcrum and the anchored end of the spring.

Abstract: A ball pitching machine which uniquely embodies a single, specially configured ball engaging wheel which is rotatably mounted within a wheel housing that, along with a ball receiving barrel, is easily rotatable through an angle of 270 degrees. With this novel construction, the device can be used to accurately pitch a variety of fast balls, curve balls and sliders. The ball engaging wheel of the pitching head is of a novel vaned construction so that as the wheel is rotated within its housing a negative pressure will be generated within the housing and within the ball receiving barrel which is associated therewith so that the ball will be sucked into the barrel and into positive driving engagement with the periphery of the rotating wheel.

Abstract: A motion picture film reel is constructed so as to be readily disassembled into its component parts to permit film to be removed therefrom without breaking the component parts of the reel. Furthermore, the component parts of the film reel can be rapidly reassembled for repeated reuse. Moreover, the structure is completely plastic so that it may be melted down and is totally recyclable. The film reel is comprised of a pair of side retainers that are releasably engaged with a disk-shaped hub. Each of the side retainers has a pair of posts with catches on the ends thereof which may be inserted through post receiving apertures in a transverse web in the hub. The posts are also provided with cam surfaces which interact with each other to hold the catches engaged with the web. A latching mechanism immobilizes the side retainers relative to each other and relative to the hub until or unless released.

Abstract: An aerobic conditioning apparatus for use by a trainee in simultaneously exercising the upper and lower body in a smooth shock-free manner substantially simulating movement of the arms and legs during swimming. The apparatus includes a supporting frame, first and second foot supporting assemblies mounted on the supporting frame for controlling the movement of the right and left feet of the user respectively to an oscillatory motion along first and second paths between first forward positions and a second rearward position, first and second hand engaging assemblies mounted on the supporting frame for controlling the movement of the right and left hands of the user respectively to an oscillatory motion along paths between a first upraised position and a second lowered position, and synchronizing mechanisms mounted on the supporting frame for causing synchronous movement of the foot engaging assemblies and the hand engaging assemblies.

Abstract: An electric motor or gasoline engine driven pruner by which to facilitate the cutting of generally inaccessible or hard to reach trees and shrubs. The pruner includes a rotatable drive shaft, an elongated tubular drive shaft housing surrounding the drive shaft, an electric motor or gasoline engine affixed to one end of the drive shaft housing to rotate the drive shaft, and a cutting head affixed to the outer end of the drive shaft housing to efficiently cut trees and shrubs. A unique arrangement of telescoping, concentrically aligned housing sections surrounds an arrangement of telescoping, concentrically aligned drive shaft sections to permit the pruner to be extended to reach high, and otherwise inaccessible branches and limbs or collapsed to form a compact assembly for easy transport and/or storage.
