This invention concerns a line reeling device for reeling front and back lines of a kite. The device includes a reeling mechanism comprising a first reel and a second reel which are located in an enclosure and on which the front and back lines are, in use, wound respectively. The reels are arranged so that their rotation in one direction retracts the lines and their rotation in the other direction deploys the lines. The reeling mechanism further includes reel connecting means which is operable to cause the reels to rotate in harmony in one configuration and rotate independently in another configuration. The reeling mechanism also has a braking mechanism for controlling rotation of the reels and a control mechanism which is in connection with the braking mechanism. The control mechanism is operable between a first, locked position wherein rotation of the reels is obstructed and a second, released position wherein rotation of the reels is allowed.

Embodiments of a hydraulically driven agricultural hose reel comprise a spool, a frame, the hose reel having a front end, back end, drive side, and a free side. The hose reel includes a hydraulic motor system powered by a hydraulic pump, which turns the spool though a transmission assembly. The hydraulic motor system comprises a manifold that selectively sets the hose reel to a series operating configuration, parallel operating configuration, or a free wheel operating configuration.

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 guide device for at least one line, such as an electric line of a C-arm, has a rotatable first cylinder with a first cylindrical surface and a static second cylinder, adjoining the first cylinder in the axial direction and having a second cylindrical surface. A first guide element for guiding the line on the first and/or the second cylindrical surface, is disposed coaxially with respect to the first and the second cylinder and it is movable relative to the first and the second cylinder. The line can be wound up on the first and/or the second cylindrical surface or can be unwound therefrom depending on the movement of the first cylinder.

A first engaging part is located on an outer surface of a cord reel and protrudes in a first direction orthogonal to a rotation axis of the cord reel. A second engaging part is located on the outer surface of the cord reel at a position different from the first engaging part in a second direction along the rotation axis. A holder base has an opening through which the cord reel can be inserted in the second direction. One or more notches are formed along the outer periphery of the opening of the holder base and allows the first engaging part to pass therethrough in the second direction. When the cord reel is attached to the holder, the holder base is disposed between the first engaging part and the second engaging part in the second direction.

Disclosed is a shoelace folding and releasing device, comprising: a thread reel used for winding thread, a knob device in transmission connection with the thread reel, and a position limiting device and arresting disk arranged between the thread reel and the knob device. After the knob device is pressed, both the thread reel and the arresting disk are locked with the knob device. The arresting disk restricts the clockwise or counterclockwise rotation of the knob device, and the knob device drives the thread reel to rotate so as to tighten a shoelace. When the knob device is pulled out, both the thread reel and the arresting disk are unlocked from the knob device, and the thread reel releases the shoelace, and at the same time, the position limiting device restricts the separation of the knob device.

The present invention provides a telescopic jacking stepwise rollback-type reel sprinkling irrigation machine, including a chassis, a locking-type reel, a sprinkling irrigation apparatus, and a stepwise driving apparatus. A locking channel in a circumferential direction is disposed on the locking-type reel. The stepwise driving apparatus includes a lifting cylinder, an upper caliper, and a lower caliper, and the upper caliper and the lower caliper are clamped to be mounted on the locking channel. Pressurized water is used in the telescopic jacking stepwise rollback-type reel sprinkling irrigation machine to drive the lifting cylinder to realize periodic lifting motion of the piston rod, so as to drive the upper caliper to move up and down to be engaged with the locking channel of the locking-type reel intermittently, thereby driving the locking-type reel to roll back intermittently to automatically reel in a sprinkling irrigation PE hose.

This device disclosed herein can allow portable and efficient rolling and storage of hand wraps, gauze, bandage wraps and ties. In one non-limiting example, the case can be used for athletes in the sport of boxing to neatly roll and store their boxing hand wraps after use. In one non-limiting example, the device can incorporate a manual spindle and reel while another can incorporate a battery and motor to rotate spindle. The case can be incorporated into many different types of materials. Preferred embodiments of this wrap case and roller device and methods of use are disclosed herein.

A fall protection device and its safety belt base. The fall protection device adapted to be connected to a safety belt includes a frame, a shaft, and a safety belt base, wherein the frame has a receiving place. The shaft is disposed on the frame. The safety belt base fits around the shaft and is located in the receiving place. The safety belt base includes a first portion and a second portion. The first portion has a ring, and the second portion has a sleeve and a reinforcement portion connected to the sleeve. The sleeve is surrounded by the ring and is adapted to be connected to the safety belt. The reinforcement portion is embedded in the ring. With the reinforcement portion, the structural strength of the safety belt base could be reinforced, and the first portion and the second portion could be prevented from disengaging from each other.

A cable retractor enclosure having a weighted cable pulley and cable pulley guide rails. The cable pulley is rotatable about a pivot and configured to translate along grooves when a cable wrapped underneath is extracted from the cable retractor enclosure. The cable extends outside of the retractor enclosure from its upper end and provides a cable end plug that sits within a retractor module insert. Weights may be attached to the cable pulley in order to leverage gravitational forces, which result in a bias causing the cable to retract back into the enclosure. Friction forces against the extracted cable can be used to prevent the gravitational bias the cable pulley exerts (retraction forces) on the cable by bending the cable to lay flat onto a table surface.
