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.

The present invention relates generally to medical equipment, more particularly, the use of fluid hoses coupling tanks to cannulas, as part of medical gas therapy, such as oxygen therapy. The invention describes a collection system for managing excess flexible hose that a patient might need to wear for medical reasons such as home oxygen medical therapy. It comprises a collection container, a non-spooling roller system for collecting excess hose into the collection container and extraction from the collection container, and power system to power and control the roller system.

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 manual mechanism for immediately locking a retractable lanyard is proposed where the locking mechanism is easily manipulated by the user and locks the assembly immediately with a precise, desired amount of cable exposed. The mechanism takes the form of a set of spring-loaded locking pins that engage the tracks on the top of the cable spool. A lever controls the spring and moves the pins between engaging with the spool (the locked position) when the spring is compressed, and unlocked when the spring is relaxed and the locking pins are retracted. This mechanism can be added to or manufactured within a lanyard to override the existing latching mechanism.

A string fastening device which may be used for easily winding and fastening strings provided in shoes, bags, clothes, or the like is provided. The string fastening device includes a base; a fixation member coupled to the base to maintain state in which the bobbin is stored in the base; a rotational member coupled to the fixation member and rotating the bobbin; and a string suspension member provided in the bobbin and fixing a string.

This invention is directed toward a portable and easy to set up retractable cord system with means to allow athletes to move along specified routes and to form space indicators that show zone areas.

A pipeline inspection device including a cable having a camera disposed on a distal end of the cable, where the camera and the cable are configured to be directed into a conduit. A first drum includes a rear wall, a front wall, and a side wall defining an interior, where the front wall has an opening providing access to the interior, and where the cable is disposed at least partially within the first drum. A stand supports the first drum, where the first drum is rotatably coupled to the stand. A hub houses electrical components of the pipeline inspection device. The hub is removably received in the interior of the first drum via the opening, where the hub is selectively removable from the first drum and insertable into an interior of a second drum.

According to an aspect of an embodiment, provided is a downhole depth measuring apparatus. The downhole depth measuring apparatus comprises a frame, a cable reel rotatably supported upon the frame, a length of cable carried upon the cable reel, and a level wind assembly supported on the frame for level distribution of the cable on the cable reel during retrieval of the cable. The level wind assembly is operably coupled to a stationary counter assembly.

A tubing system and a tubing cartridge are provided. The tubing system includes a housing having a front portion, side portions, a rear portion, a top portion, a bottom portion, and an internal portion; at least a first length of tubing positioned within the internal portion; and a first opening extending through the housing from the internal portion to an external portion thereof; wherein a first end of the first length of tubing retractably extends through the first opening. The tubing cartridge includes a body portion and at least one length of tubing substantially enclosed within the body portion, wherein the at least one length of tubing comprises a first end retractably extending through an opening in a front section of the body portion.

A pet walking device for walking a plurality of pets comprising a top housing with a handle and a bottom housing; a swivel coupling rotatably coupling the bottom housing to the top housing for 360 degree rotation; a plurality of co-axial overlapping spool assemblies independently rotatably disposed within the bottom housing; and a leash carried by each of the plurality of co-axial overlapping spool assemblies.
