A retractable leash with improved locking and unlocking mechanism, having a housing; a spool disposed inside the housing and biased towards the winding direction; a braking means; a locking means rotatable between a locking position to stop rotation of the spool towards the unwinding direction and an unlocking position; a biasing means which biases the locking means towards the unlocking position; a press button pivotable between a pressed position and a released position; an actuating means rotatably engaged with the press button and the locking means between a default position and an actuating position; and a sliding button having an upper portion exposing on the upper portion of the press button and a lower portion extending downwards through the press button into the housing.

A temporary horizontal lifeline device includes a main frame, a central shaft pivotally arranged on the main frame, a drum and an external gear affixed on the central shaft, a spanner adapted for driving the central shaft to rotate, and a cable member winded around the drum. A gear groove is arranged on the periphery of the external gear. A first spring is arranged on the main frame so as to provide a force to enable the drum to retrieve the cable member. The main frame also comprises a brake element and a detent provided thereon. The brake element has a first state for restrict the gear groove and a second state for releasing the gear groove, which prevents the external gear from rotating forward and backward when the external gear is in the first state. The detent has a first position to mesh the gear groove and a second position to release the gear groove, so that the external gear is only allowed to unidirectionally rotate in the first position. Accordingly, the present invention is convenient and safe to use when conducting retrieving operation, and effectively improves the stress concentration issue of conventional detents.

The present invention is a retractable pet leash with a variable brake system to control a pet. The variable braking system can be engaged or disengaged by the user via 3 methods. The first method is via a handle that is directly connected to the brake. The second method, also actuated by the user is a one touch brake system that uses the rotation of the reel to slowly apply the variable brake over several rotations of the reel. The third method allows the user to set the length of the leash cord and when the set length of the cord is met, engages the one touch brake system. The retractable pet leash provides a system to set the length of the leash cord being let out and ensures that the leash cord is kept taught between the user and the pet and notifies the user when the set length has been reached and applies variable braking in a steady and predictable manner to smoothly stop the pet.

A retractable leash assembly for a pet animal, such as a dog, is provided. The leash assembly includes a casing body with a handle attached to the body by an at least one hinge joint, a braking device, and a spool arrangement with an extendable lead line wound thereabout and configured attachable to the pet animals' collar or harness, wherein in the leash assembly the handle is configured to articulate about the joint with regard to the casing body, the articulation movement of the handle being triggered by the pulling force exerted on the lead line by the animal kept on the leash, and wherein, by virtue of the articulation movement the braking device actuates a braking action causing the lead line to reduce unwinding speed proportionally with an increase in the pulling force.

A self-retracting device includes a housing assembly having a first housing cover removably connectable to a second housing cover. The self-retracting device further includes a rotatable hub received within an interior of the housing assembly and having a line associated therewith, and retraction member received within an interior of the housing assembly between the rotatable hub and the first housing cover. The self-retracting device further includes an axle having a first end fixedly but removably connected to the first housing cover, a body extending through the retraction member and the rotatable hub, and a second end in engagement with at least a portion of the rotatable hub.

Techniques for implementing a pipe deployment system that includes a pipe reel, in which the pipe reel includes reel ends and a reel drum and the pipe reel enables a pipe segment to be wrapped on the reel drum. The pipe deployment system includes a brake assembly with a brake wheel having a shaft socket keyed with flat inner surfaces, and a shaft adapter assembly, which includes an adapter head to be coupled between the pipe reel and the brake assembly. The adapter head includes an adapter shaft keyed with flat outer surfaces, in which the adapter shaft matingly interlocks with the shaft socket and is to be partially inserted through a reel end of the pipe reel, and a rotation control pin coupled to the adapter shaft, in which the rotation control pin is to be inserted between adjacent reel spokes in the reel end of the pipe reel.

A braking system for a hose or cable reel including a housing configured to fit inside a drum of the reel and to rotate with the drum during use, and a gerotor including inner and outer gears disposed inside the housing, wherein the inner gear is attachable to a shaft of the reel and the outer gear is configured to rotate relative to the inner gear with the housing during use thereby causing hydraulic fluid to be pumped through the gerotor and impede rotation of the drum.

A cradle apparatus and method for transporting and/or deploying a coil of pipe supported around a reel are disclosed. The cradle apparatus can include a first arm member and a second arm member each having a male segment and a female segment capable of telescopic movement. A first set of pipe reel engagement spools and a second set of pipe reel engagement spools can rotate to raise/lift a first flange and a second flange of the reel thereonto when the pipe reel is positioned between the first arm member and the second arm member and the proximal end and the distal end of the first arm member and the second arm member are brought closer together due to telescopic movement of the male and female segments.

A cable recovery machine, comprising at least one traction module configured to hold and draw at least one cable, in particular of a cable laying plant; the traction module comprises a frame on which one or more traction wheels and one or more idle wheels are positioned; between the traction wheels and the idle wheels a space is defined for the passage and traction of the cable to be recovered; the idle wheels are provided with a support connected in a mobile manner to the frame of the traction module and provided with actuators configured to press the idle wheels against the cable that passes between them and the traction wheels, so that the space between the idle wheels and the traction wheels can be automatically adjusted on the basis of the external diameter (D1, D2) or thickness of the cable drawn.
