Abstract: A medical tubing connector pair includes a female tubing connector, and a male tubing connector. The female tubing connector has an external thread and the male tubing connector has an internal thread, the external and internal threads threadingly engaged to secure the female and male tubing connectors together. The internal thread is made from a flexible material to permit the female and male tubing connectors to be connected to or disconnected from each other without rotation of the tubing connectors relative to each other.

Abstract: A coupling mechanism secures a shaft-to-collar connection for two shafts, such as an extension shaft stub and a tractor PTO shaft. An annular locking element on the first shaft prevents an axial disconnection of an established connection. One of the shafts has a collar with a positive engagement element for a locking engagement with the other shaft. The other shaft includes a positive engagement for a locking engagement with the collar. To enable an easier handling of the axial locking of the shaft to collar connection, the locking element includes a first set of teeth which are complementarily to a second set of teeth on the second shaft. The locking element is rotatably arranged on the first shaft and can be rotated from a locked position to an unlocked position. In the locked position the teeth overlap.

Abstract: A set (10), including a first component (12) having one or more stub portions (16) extending from the first component (12), the one or more stub portions (16) being formed with at least one set of radially extending teeth (22) separated circumferentially by troughs (24), and a second component (14) having a socket portion shaped to receive one of the stub portions (16), wherein peripherally spaced formations (30) are provided on an interior surface of the socket portion. The stub portion (16) is able to be received within the socket of the second component (14) by aligning the teeth (22) of the stub portion (16) between the formations (30) of the socket, and wherein the stub portion and socket are thereafter connected by relatively rotating the first (12) or second components (14) such that the teeth (22) of the stub portion engage the formations (30) of the socket to couple the first and second components together.

Abstract: A saltwater fishing assembly includes a body resembling a forage fish. The body includes a quick connect device that is swivelable relative to a fishing line and is reelable to a fishing rod tip. A quick connection subassembly is connectable to the quick connect device of the body and includes a hook and is releasable with a hooked fish. Methods of using the fishing assembly are also provided.

Abstract: A frame joint system including a first frame member and a second frame member. The frame members include laterally opening channels running axially thereof. The frame members are adapted to be rigidly secured together by quick release coupling. Embodiments of the frame joint system include mitered corner, end-to-face, face-to-face and end-to-end joints. The quick release coupling includes at least a first sleeve member and a gripping member. The gripping member is nested within the first sleeve member, and the first sleeve member is nested within the first frame member. The gripping member includes gripping elements that mate with a slot in a box rail element fixedly associated with the second frame member. Activating the gripping elements pulls the two frame members together into a rigid joint.

Abstract: A tool holder (1) and a shank (8) for quick mounting and dismounting an annular core bit (2) both include cooperating respective guide members (4, 4?) provided at their bit-side ends, flanges (3, 9) arranged coaxially with the guide members (4, 4?) for axially locking same and having, respectively, outer and inner threads, and outer and inner cone surfaces (6, 10) located inwardly of the respective guide members (4, 4?) and axially spaced therefrom. The outer and inner cone surfaces (6, 10) taper toward their respective bit-side ends. The tool holder and the shank have cooperating torque transmitting elements (5, 5?) arranged between the respective inner guide members (4, 4?) and the respective outer cone surfaces (6, 10).

Abstract: Adjustable handle (1), of the type comprising an operating lever (2) ending into a cylindrical or prismatic body (3) inside which there is slidably mounted a tightening member (4) carrying a bushing or a stud (5), the cylindrical or prismatic body (3) and the tightening member (4) comprising fellow toothings (6) kept in reciprocal engagement by a spring (7), and a check element (8) onto which is imparted a pressure to overcome the action of the spring (7) and remove the engagement between said toothings (6). In said handle (1), said check element is in the form of a control push button (8), in one piece with the tightening member (4), said push button (8) incorporating a seat (9) accessible from its operating surface (10) to insert therein a mounting/removal tool.

Abstract: The invention relates to a mechanical connection for transmitting torque, demonstrating a common longitudinal axis a shaft rotating around the longitudinal axis and a hub coaxial to the shaft, its inside contour surrounding the shaft via a slaving section, wherein in the area of the slaving section, the shaft and the inside contour of the hub comprise of at least one retaining section with out-of-round cross section for transmitting torque. In the region of the slaving section, at least one of the shaft or the hub demonstrates at least two retaining sections angularly displaced to each other around the longitudinal axis.

Abstract: An improved female splined member includes a female tubular member having an inner surface provided with a plurality of longitudinally extending grooves that are sized and spaced in accordance with a desired number and position of splines to be formed. A plurality of elongate rods is disposed in respective longitudinally extending grooves formed in the inner surface of the female tubular member. A quantity of positioning material is provided within spaces provided between the elongate rods and the longitudinally extending grooves. The positioning material is hardened to support the elongate rods in the longitudinally extending grooves to define a plurality of inwardly extending splines in the female splined member. An improved method for manufacturing a female splined member includes the initial step of providing a female tubular member having an inner surface provided with a plurality of circumferentially spaced, longitudinally extending grooves.

Abstract: A driven tool includes a driven part which is rotatably driven by a drive part. The driven part and the drive part are coaxially arranged one inside of the other. The drive part and the driven part are conical as viewed in a longitudinal section plane containing the axis. The driven part includes driven teeth projecting generally radially with respect to the axis and received in respective radially-open recesses formed in the drive part. Each of the driven teeth makes contact with a wall of the respective recess at first and second contact places which are respectively situated on opposite sides of a generally radial line of symmetry of the driven tooth. The contact places are operable to transmit a drive force from the drive part to the driven part in respective directions of rotation. A driving angle in the range of −5° to +45° is formed at each contact place.
