A retractable leash device is comprised of a housing with a handle, and a leash wound around an internal reel. The reel is biased by a spring to automatically retract the leash. A momentary unidirectional lock in the housing is arranged to be normally disengaged from unidirectional teeth on the reel. When the momentary unidirectional lock is actuated, the reel is engaged by a ratchet to prevent rotation in the release direction but permit rotation in the retract direction. A toggle lock in the housing is movable between an unlocked position away from the reel, and a locked position between cogs on the reel. A geared rotation damper is engaged with a concentric gear on the reel to limit retraction speed. A clip attached to the housing may be clipped around the leash when the leash is wrapped around a fixed object.

In repairing soft tissue with a bone anchoring instrument (such as reattaching a tendon of a torn rotator cuff), the bone anchoring instrument may be used to anchor the soft tissue to a region of bone. The anchors inserted into the underlying bone may have one or more lengths of suture or wire attached thereto which may be tensioned independently of one another to affix the soft tissue to the bone by having a selector mechanism selectively engage and disengage ratcheted tensioning wheels from one another. Suture loading mechanisms may be employed for passing suture lengths into and/or through the anchors prior to deployment into the bone where such mechanisms may employ suture snares which are configured to reconfigure from an expanded shape through which suture lengths may be easily passed to a low-profile shape which secures the suture lengths within the snare.

An upright suitcase includes a front section and an opposing rear section, each having an outer panel and a circumferential wall with a bottom edge and a plurality of free edges. The bottom edges are hingedly connected for movement of the opposing front and rear sections between an open position, in which access to the opposing sections is provided, and a closed position, in which all of the edges of the two circumferential walls are in juxtaposition. A zipper closure engages the opposing sections and selectively holds the free edges of the circumferential walls in juxtaposition. A divider panel is positioned within the upright suitcase to at least partially divide the opposing sections from each other when in the closed position. The divider panel has one end flexibly tethered to the rear circumferential wall and is movable into and out of the rear section. Slack connectors connected to the rear circumferential wall are positioned to selectively and flexibly connect the free end of the divider to the rear circumferential wall. Retainer straps connected to the rear section are positioned to engage the divider and draw it toward the outer panel of the rear section.

The system embodying the invention is employed to cool the interior of a normally closed area such as a garage or storage area, and/or to remove any noxious fumes or undesirable odors from inside the garage by moving outside air into the garage and providing means for that inside air and the fumes or odors in it, if any, to be removed to the outside ambient atmosphere. The system includes one or more fans installed in the upper section of the garage door, and the garage door is opened or closed by moving it in any well-known manner either by rolling it's hinged panels upward to a horizontal position from its normally-closed vertical position, or, when it is a solid door, tilting the entire garage door so that it is substantially horizontal instead of vertical and is located above the garage floor a sufficient distance to drive vehicles that will fit into the garage though the door opening. Those fans have a power cord that extends from a power supply position generally near the garage door opener that is secured to the garage ceiling and powers the garage door from its closed position to its open position, and vice versa, and that power cord is also secured to the garage door in the vicinity of the fan or fans used to move air into and out of the garage when the garage door is closed. The power cord is spring-urged to minimize its relatively free section between the power source and the place where it is secured to the garage door in the vicinity of the fan or fans where it provides power to the fan motor or motors when desired and appropriate. In the preferred embodiment the power cord is wound on a reel that is spring loaded to urge the reel in the rotational direction to wind the part of the power cord that is between the reel and the fan motor or motors, keeping the relatively free section of the power cord in tension so that it does not form any dangerous hanging loops when the garage door is moving from its open position to its closed position. There are also lesser desirable alternatives to apply a spring-loading to the power cord to keep it sufficient tension that it does not form such loops when the garage door is being opened.

The invention provides a variable propeller device for a wind motor blade, which comprises a drive unit and a transmission gear which drives the blade to rotate, wherein the drive unit such as a hydraulic cylinder or a feed screw nut can generate linear propulsion to drive a push-and-pull rod in the transmission gear to perform linear movement; the push-and-pull rod drives a first flexible element and a second flexible element which are coated on the tail of the blade; and the first flexible element and the second flexible element drive the blade to rotate, so as to realize variable propeller. When the number of the blades of a wind motor is more than two, a linkage frame can be arranged between the drive unit and the push-and-pull rod of the transmission gear, and drives the transmission gear to perform linear movement, so as to realize synchronous variable propeller of various blades.

A machine and method for horizontally stretching and exercising the human body, specifically the human frame or torso. The machine comprised a bed, table, or platform having three main sections: an upper stationary section upon which user's upper body is physically attached, an actuated lower section which receives the user's lower body, and a slack section, including an upright projection, disposed at the end of the lower section of the bed, table, or platform. A strap or similar device is connected between a pelvic harness worn by the user and the upright projection of the slack section. While lying atop the upper and lower sections of the machine, the user self-actuates movement of the lower and slack sections of the machine away from (or towards) the upper body, thereby causing the strap to pull upon (or loosen from) the user's trunk or midsection. Because the user's upper body is physically attached to the stationary upper section of the machine, the user's trunk is effectively stretched and exercised by outward movement of the strap to the extent desired by the user.

A leash system for controlling the slack in the leash to prevent the animal from becoming entangled in the leash. The leash system has a spool mounted wire controlling the effective length in the leash by forming a loop in the leash to absorb any slack. If the animal pulls away from the person and additional leash length is required, wire can be automatically played out from the spool so that the loop can be opened to provide the required slack. Similarly, the wire will automatically retract to reform the loop and absorb the slack the leash once the animal moves back toward the person such that the effective length of the leash remains relatively taut.
