A curtain winding device includes a beam, a power mechanism mounted to the beam, a transmission rod driven by the power mechanism to rotate, and two reels fitted about the transmission rod and relatively fixed with the transmission rod in a circumferential direction. Each reel is wound with a drawstring. A drawstring holder is disposed on the beam to guide the drawstring to be wound on the reel. The beam is fixed with a nut. Each reel includes a screw segment screwed to the nut, and a cone segment gradually increasing in an outer diameter along an extending direction. An end of the reel away from the screw segment is provided with a fixing portion for fixing a distal end of the drawstring, and a positioning portion protruding from an outer side surface of the reel to abut against the drawstring holder to position an initial position of the reel.

The present disclosure relates to a gate system for an overhead lifting rail system, comprising: a first gate comprising: a rail portion for supporting a lifting carriage; and a bridging element pivotally coupled adjacent a proximal end to the rail portion; and a second gate comprising: a rail portion for suspending a lifting carriage; and a bridging element support portion. Upon the first gate engaging with the second gate, a distal end of the bridging element of the first gate engages with the bridging element support portion of the second gate to form a bridge between the first gate and the second gate; and the distal end of the bridging element and the bridging element support portion are configured such that the ends of the bridging element are substantially aligned with the respective ends of the rail portions of the first and second gates.

A tether includes a housing defining a cord aperture, a spool located within the housing and configured to rotate about a spool axis in either an extending direction or a rewinding direction, a cord wound around the spool and configured to pass through the cord aperture, a biasing member coupled to the spool, and a retractor lock. The biasing member biases the spool to rotate in the rewinding direction to retract the cord into the housing. The retractor lock is movable between a locked position and an unlocked position. The retractor lock prevents rotation of the spool when in the locked position and allows rotation of the spool in the unlocked position. The retractor lock is moves from the locked position to the unlocked position in response to a threshold cord force on the cord.

A device tethering system is provided for securing a device to a source location as may be assisted by a tether. The device tethering system may include a retraction component, tether, pouch, belt, device mounting component, device aspect of the device mounting component, and/or tether aspect of the device mounting component. A method for securing a device to a source location using the device tethering system is also provided.

A tool-operated adjustment device includes a housing supporting a rotatable spool that is operably coupled to a tension line. The spool is configured to rotate about a first axis in a first direction to wind the tension line, and to rotate in a second direction opposite the first direction to unwind the tension line. The device includes a socket pivotally coupled to the housing and configured to rotate about a second axis. The socket is selectively coupled to the spool to drive rotation of the spool in the first direction. The socket is configured to removably connect and disconnect to a tool configured to rotate the socket about the second axis. The device includes a release mechanism that is configured to selectively release the spool such that the spool is free to rotate in either the first or second direction in response to manual forces applied to the release mechanism.

A multipurpose accessory and storage system for an electronic device includes a housing member attaching to the electronic device and a charging station structured on the housing member to charge, arrest and dispense an accessory item. The accessory item includes a protective membrane housing a logic board, a power component, an image sensor, a transmitter configured to transfer a signal or data to the electronic device or the housing member and a software program stored in the logic board. The transmitter establishes a pairing or electronic connection between the electronic device or the housing member and the accessory item. The pairing or electronic connection enables content captured by the image sensor to be relayed to the electronic device to permit a user to view the content on the display of the electronic device and/or to control components and features of the accessory item via the electronic device.

The present disclosure is directed to overhead door assemblies and operating systems. Disclosed herein is a drive drum that is compatible across a variety of overhead door types, including, for example, standard lift doors, vertical lift doors, and high lift doors. The drive drum of the present disclosure comprises a first cable groove section and a second cable groove section, opposite the first cable groove section, wherein at least one of the first cable groove section or the second cable groove section is in a non-linear graduated arrangement.

The present disclosure provides a damper and an anti-irritable tractor, which relates to the field of pet traction devices and solves the problems that the damper has a short service life and the tractor is easy to lose the anti-irritable effect. The damper comprises a magnetic component and a damping plate, which are magnetically adsorbed and synchronously rotate or stand still when the rotating speed of a winding reel is less than the set speed; when the rotating speed of the winding reel exceeds the set speed, either of the magnetic component and the damping plate is connected with the winding reel, and the other of the magnetic component and the damping plate is connected with a stationary part, and when the magnetic component and the damping plate rotate relatively, the magnetic adsorption force between the magnetic component and the damping plate forms the resistance to limit the rotation of the winding reel. According to the damper, the adsorption force between the magnetic component and the damping plate can form the resistance to limit the rotation of the winding reel. The magnetic component and the damping plate are bonded and magnetically absorbed, and damping materials such as adhesive oil do not need to be filled. The heat generated by friction of the damping materials is reduced, and there is also larger magnetic force in case of abrasion, thus greatly prolonging the service life.

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.
