Abstract
The present invention is a two or more subject retractable leash retractable leash, and methods of use regarding the same, which includes a roll-back feature on the retractable leash. The leashes may be locked in place by engaging a single lever. The leashes retract regardless of whether the spools are locked or unlocked. The leashes retract independently of the other leashes, such that a dual leash may be used to walk one subject.
Claims18
A retractable roll-back leash apparatus for multiple leash subjects comprising:
- a main housing having a interior;
- first and second spools disposed in the interior of the main housing;
- first and second brakes, the first brake being configured to engage the first spool and the second brake being configured to engage the second spool;
- a lever having a user gripping portion and an actuator arm extending between an interior of the user gripping portion and the interior of the main housing, the actuator arm being configured to control the operation of the first and second brakes in response to a user operation of the lever;
- and
- first and second of leashes, the first leash being operatively connected with the first spool, the second leash being operatively connected with the second spool, the first and second leashes extending from the interior of the main housing, the first and second spools being configured to automatically retract the first and second leashes, respectively, during a first tension in both a brake engaged state and a brake disengaged state, the first and second spools being further configured to lock during a second tension, the second tension being greater than the first tension.

A retractable roll-back leash apparatus for a leash subject comprising:
- a main housing having an interior;
- a spool disposed in the interior of the housing;
- a brake configured to operatively engage with the spool;
- a lever having a user gripping portion and an actuator arm extending between an interior of the user gripping portion and the interior of the main housing, the actuator arm being configured to control the operation of the brake in response to a user operation of the lever;
- and
- a leash operatively connected with the spool and extending from the interior of the main housing, the spool being configured to automatically retract the leash when experiencing a first tension in both a brake engaged state and a brake disengaged state, the spool being further configured to lock during a second tension, the second tension being greater than the first tension.

A retractable roll-back leash apparatus comprising:
- a main housing having an interior;
- a spool disposed in the interior of the main housing;
- a brake configured to engage the spool;
- a leash operatively connected to the spool and extending from the interior of the main housing;
- a lever having a user gripping portion and an actuator arm extending between an interior of the user gripping portion and the interior of the main housing, the actuator arm being configured to control the operation of the brake in response to a user operation of the lever;
- and
- a cooperating spring configured to operatively engage with a catch, and a release cam to retract the leash in both a brake engaged state and a brake disengaged state, the spool being configured to automatically retract the leash during a first tension in both the brake engaged state and the brake disengaged state, the spool being further configured to lock during a second tension, the second tension being greater than the first tension.
4 more elements
A method for walking one or more leashed subjects, comprising:
- providing a retractable leash device having,
- a first retractable leash,
- a second retractable leash,
- a rotatable main housing, each of the first and second retractable leashes being configured to retract independently of one another by operation of a cooperation spring, a catch, and a release cam, each operatively cooperating with a first self-winding spool and a second self-rewinding spool of the first and second retractable leashes, respectively upon experiencing a first pulling tension on the first and second retractable leashes in both a brake engaged state and a brake disengaged state, the first and second retractable leashes being positioned through first and second leash openings of the rotatable main housing, and
- a lever having a user gripping portion and an actuator arm extending between an interior of the user gripping portion and an interior of the main housing, the actuator arm being configured to control the operation of a brake engaging the first and second self-rewinding spools in response to a user operation of the lever;
- attaching a first subject to the first retractable leash;
- attaching a second subject to the second retractable leash;
- locking the first and second retractable leashes by operating the user gripping portion of the lever;
- the rotatable housing rotating according to movement of the first and second subjects to prevent tangling of the first and second retractable leashes, the first and second retractable leashes being configured to automatically retract during a first tension in both the brake engaged state and the brake disengaged state, the first and second spools being configured to lock in place during a second tension that is greater than the first tension.
