Cable coupling assemblies are described which can be readily engaged and separated from one another. The couplings are particularly useful for use in torque transmitting cables such as those used in drain cleaning applications.

A hatch cover lock comprises a front member including a pair of flanges, a rear member positioned between the pair of flanges; a gap defined between front member and the rear member; a clamp defining a J-shaped cross-section in a plane normal to a length thereof, the clamp having one leg thereof disposed in the gap and having another leg thereof disposed parallel to an outer surface of the rear member and at a distance therefrom, a handle, a first pivotal connection between the handle and the front member, a gravity lock, a second pivotal connection between the gravity lock and the handle, and a weld-free connection between the main portion of the rear member and the main portion of the front member.

The present invention relates to a structural joint for attaching two boards by their butts, achieving the correct transmission of forces between them by means of a staggered configuration of the butts thereof to increase the contact surface between both boards, allowing the mutual coupling thereof, both being aligned and coplanar, and at least one of the steps of both boards having a finger profile to further increase the contact surface between both boards.

A floor joist including a first piece of lumber including a first set of fingers and a first set of grooves is provided. A second piece of lumber including a second set of fingers and a second set of grooves is also provided. A finger joint is formed by a combination of the first second of fingers with the second set of grooves and a combination of the second set of fingers with the first set of grooves. A first set of pockets are formed between the combination of the first second of fingers with the second set of grooves, and a second set of pockets are formed between the combination of the second set of fingers with the first set of grooves.

Disclosed is an engine clutch motor connection structure for a hybrid transmission. The motor connection structure may be configured for coupling a rotor of a motor and an engine clutch retainer in the hybrid transmission. An example motor connection structure includes a damping unit coupled to an outer circumferential surface of the retainer in an axial direction of the rotor on an inner side of the rotor and supporting each of (i) the outer circumferential surface of the retainer, (ii) an inner circumferential surface of the rotor, and (iii) a coupled portion of the retainer.

A component that is to be mounted so as to be rotatable about an axis of rotation and transmits torque along with a rotating partner includes a first serration that extends about the axis of rotation and is to mesh with the rotating partner which has an adequate second serration mating with the first serration. The first serration has a plurality of teeth which have tooth tips extending substantially in the direction of the axis of rotation and tooth valleys located between the tooth tips. The tooth tips of the first serration each have a meshing edge forming a first line, while the tooth valleys located between the teeth each define a second line. At least two adjacent second lines intersect at an imaginary point lying between the axis of rotation and the maximum circumference of the first serration, in the semicircular surface beyond the axis of rotation.

A floor joist including a first piece of lumber including a first set of fingers and a first set of grooves is provided. A second piece of lumber including a second set of fingers and a second set of grooves is also provided. A finger joint is formed by a combination of the first second of fingers with the second set of grooves and a combination of the second set of fingers with the first set of grooves. A first set of pockets are formed between the combination of the first second of fingers with the second set of grooves, and a second set of pockets are formed between the combination of the second set of fingers with the first set of grooves.

A connector for connecting two furniture modules or other stationary objects to form a modular system. The connector includes two hardware pieces, to be mounted onto two furniture modules, respectively. The first piece fits into the second piece in a loading/unloading position, and then moves to a locked position. One or more detent on one hardware piece and one or more systems of tracks in the other hardware piece are provided to help the two pieces move relative to each other in a guided manner, go into and stay in the locked position, and move out of the locked position into the loading/unloading position when sufficient force is applied. Each system of tracks includes multiple indentations and one or more barriers, where the detent can move along the indentations and is resisted or blocked by the barriers.

A floor stand system for mounting an electrical box above a floor includes an electrical box mount having a mechanical interface thereon. A set of substantially interchangeable floor supports have mating mechanical interfaces at their upper ends for connecting to the mechanical interface on the electrical box mount. The set of floor supports includes a plurality of floor supports having different fixed lengths. The floor supports are substantially interchangeable so that one of the floor supports having a fixed length suitable for supporting the electrical box mount at a desired elevation above the floor can be selected and connected to the electrical box mount using the mechanical interfaces to create a floor stand suitable for supporting the electrical box mount at the desired elevation above the floor.

A construction system uses a comb connector element in combination with flat or generally planar polygonal shapes of various types. The comb connector elements connect to the edges of the planar polygonal shapes. Each comb connector has at least one pair of connector members. Each connector member has a proximal end connected to the polygonal member, and a distal end. Each connector member having a face portion that includes a recess extending from a central region of the face portion. The recess extends to the distal end of the face member.
