The cord reel device includes a reel body provided with a rotation shaft, a housing that stores inside the reel body in a rotatable manner, and a cord which is wound around the reel body so as to be extractable and which is extracted to an outside through an opening of the housing. The reel body has disk-shaped members on a plane perpendicular to the rotation shaft, and the cord is stored in a space formed between the disk-shaped members. A guide section inclined relative to the rotation shaft of the reel body is provided around peripheries of the disk-shaped members of the reel body. While the cord is wound around the reel body, the guide section guides the cord to the rotation shaft of the reel body.

A pull-out type cord winding module, comprising a rotary wheel (6) which a cord (7) is wound on and which is connected with a coil spring (5), and a stopper mechanism working cooperatively with the rotary wheel (6) and including a functional rail, a ball (3) and a rolling assisting device. The functional rail comprises a locking rail, a communicating rail (25) and annular rails (21, 22) which are connected, groove-shaped and arranged around an outer circumference of the rotary wheel (6). A guide groove (91) is provided on the rolling assisting device, and two ends of the guide groove (91) are located at the upper and lower sides of the outer circumference of the rotary wheel (6) respectively. The guide groove (91) cooperates with the functional rail to hold the ball (3). When the rotary wheel (6) rotates, the ball (3) rolls in the functional rail to lock or unlock rotation of the rotary wheel (6).

A fastening device includes a main part and a fastening member. The main part is composed of a base, a spool, a knob and an engaging unit. The fastening member disposed at the main part. The spool is disposed at the base. The knob disposed at the base includes a spiral track. The engaging unit coupled to the spool includes a guiding portion coupled to the spiral track. The guiding portion is limitedly moved along the spiral track by rotating the knob such that the engaging unit has a first position and a second position relative to the knob. The engaging unit prohibits the spool from rotating toward a releasing direction when the engaging unit is at the first position, and the engaging unit allows the spool to be rotated toward the releasing direction when the engaging unit is at the second position.

An automated aisle runner includes an automated control unit, an aisle runner, and a mobile runner extender. The automated control unit includes a housing and a runner roller, wherein the runner roller is rotatably mounted within the housing. The aisle runner is disposed around the runner roller, such that the aisle runner is wound around and unwound from the runner roller as the runner roller is rotated by a motor. The mobile runner extender is provided to ensure the aisle runner is extended in a straight, smooth manner, eliminating problematic tangling. A plurality of lights may be positioned along the aisle runner and a projector integrated into the automated control unit to provide enhanced visual effects, while a speaker provides audial effects. A microcontroller allows a user to control the color and pattern of the plurality of lights, projections, and the audio files played through the speaker.

An ergonomic hose load platform for a fire fighting vehicle is provided. The ergonomic hose load platform includes a platform and at least one pivot mount defining a pivot axis. The platform is pivotable about the pivot axis to open and close the platform.

A wiper ring provided includes a ring body and a number of brushes. The ring body has an outer side surface and an inner side surface opposite to the outer side surface. The wiper ring includes a mounting portion located on the outer side surface. The ring body is mounted to a cable through-hole of a charging pile via the mounting portion. The number of brushes are arranged on the inner side surface. Each of the number of brushes has an end fixed to the inner side surface of the ring body and the other end, opposite to the end, faces a center of the ring body or a defined point of the ring body. The number of brushes cooperatively form a through-hole having a diameter less than that of the cable for allowing a cable to pass through. A charging pile using same is also provided.

A hose reel includes a frame, a reel, a rewind mechanism with a spring and a guide mechanism with a guide. The guide mechanism moves the guide back and forth on a path while the reel is rotated for distributing the hose evenly onto the reel by the guide. To obtain a freestanding hose reel with a rewind mechanism the hose reel includes a ground support with contact areas supporting the hose reel from a base. The frame is attached to the ground support in a position where the rotation axis of the reel is perpendicular relatively to the base, and the reel is provided with a hose joint in a lowermost part of the reel and the guide mechanism is configured to move the guide to a lowermost point of the path when the hose is completely pulled out from the reel.

A vacuum hose reel assembly has a spiral torsion spring. One end portion of the spiral torsion spring is received in a slot defined by a spring holder. As a vacuum hose is unwound from the reel, the spring is wound as the reel turns in a first direction. To wind the vacuum hose back on the reel, the spring unwinds and turns the reel in a second, opposite, direction. In the event that the forces between the end portion of the spring and the spring holder become too high, the end portion of the spring disengages the spring holder such that the end portion of the spring turns about the spring holder, thereby preventing the spring from breaking.

A protractible and retractable mast system for an autonomous mobile robot includes an elongate flexible member including a first lateral end and a second lateral end, and a fastener having a first portion extending along a length of the first lateral end and a second portion extending along a length of the second lateral end. The flexible member is configured to be at least partially coiled within a body of the robot, and a portion of the flexible member is vertically movable away from the body when the flexible member is being uncoiled. The fastener is configured to connect the first lateral end to the second lateral end when the flexible member is being uncoiled, and disconnect the first lateral end from the second lateral end when the flexible member is being coiled.

A distribution station includes a mobile trailer, a pump, a manifold, a fluid line connecting the pump to the manifold, and a bypass line leading into the fluid line between the pump and the manifold. The bypass line permits fluid to be provided to the manifold without use of the pump. Reels on the mobile trailer are individually connected with the manifold, and hoses are connected with a different one of the reels. Valves on the mobile trailer are situated between the manifold and different ones of the reels. Fluid level sensors are connectable to the ends of different ones of the hoses. A controller is configured to individually open and close the valves responsive to the fluid level sensors.
