Abstract

Disclosed is a two-pet no-tangle retractable leash device including an axle having a rod opening and a first spool including a first leash and a second spool including a second leash rotatably mounted on the axle. Each leash has a proximal end attached to the spool and a distal end extending through one of two leash openings. Additionally, each spool has a spool brake element and a return spring, where a proximal end of the return spring is connected to the spool and a distal end of the return spring is connected to the axle. When a force is applied to pull on the leashes, the spools rotate thereby unwinding the return springs. When the force is removed, the return springs rewind forcing the spool to rewind the leash to its original position. The device further includes a shaft having a proximal end and a distal end, a brake rod having a distal end passing through the rod opening and the proximal end passing through the shaft; a brake connected to the distal end of the brake rod; and a brake spring positioned on the brake rod between the brake and the axle, wherein the shaft rotation around the shaft axis and the spools'"'"' rotation around the axle axis is enabled when the brake is not engaged and disabled when the brake is engaged. A housing has a lock for lockably engaging a respective spool. A handle is attached to a proximal end of the shaft and a cowling portion covers an area between the handle and the housing.

Claims

1. A one-hand operable two-pet no-tangle retractable leash apparatus comprising:

an axle and a shaft;

first and second spools mounted on the axle, each spool having a spool brake element and a return spring for retracting a leash; and

a brake attached to a brake rod, in a position engageable with said spool brake elements, the brake rod passing through the shaft.

2. The apparatus of claim 1, wherein a rotation of the shaft around the shaft axis is enabled when the brake is not engaged with the spool brake elements and disabled when the brake is engaged.

3. The apparatus of claim 1, wherein a rotation of the spools around the axle axis is enabled when the brake is not engaged with the spool brake elements and disabled when the brake is engaged.

4. The apparatus of claim 1, further comprising a housing including a front panel having a first leash opening and a second leash opening for spooling and retracting the leash.

5. The apparatus of claim 4, wherein each leash opening includes a grommet for supporting the leash.

6. The apparatus of claim 4, further comprising a bearing for rotatably supporting the shaft, the bearing being affixed to the housing opposite the front panel.

7. The apparatus of claim 4, further comprising a locking device at said housing, engageable with a respective one of said spools for stopping rotation of said spool.

8. The apparatus of claim 4, wherein the first spool includes a retractable leash being spooled through the first opening and the second spool includes a retractable leash being spooled through the second opening.

9. The apparatus of claim 8, wherein each leash has a proximal end attached to the spool and a distal end extending through the first and second leash opening in a front panel.

10. The apparatus of claim 9, wherein the spools and the spool brake elements are rotatably mounted on the axle, the return springs being in a first position when the leash is fully wound on each of the spools.

11. The apparatus of claim 10, wherein proximal ends of the return springs are fixably connected to the spools and distal ends of the return springs fixably connected to the axle,

the return spring is torqued from its first position when a force is exerted to pull the leash out of the housing thereby rotating the spools,

the return spring returns to its first position when the force is terminated, thus rewinding the leash.

12. The apparatus of claim 1, wherein a brake spring is positioned around the brake rod between the brake and the axle.

13. The apparatus of claim 1, wherein the first and the second spools rotate independently of each other.

14. The apparatus of claim 1, further comprising a housing, and a handle attached to the shaft, and a cowling portion at said handle for covering an area between said handle and said housing.

15. The apparatus of claim 14, further comprising a locking device on said housing, engageable with a respective one of said spools for stopping rotation of said spool.

16. A two-pet no-tangle retractable leash device comprising:

an axle having a rod opening;

a first spool including a first leash and a second spool including a second leash rotatably mounted on the axle,

each leash having a proximal end attached to the spool and a distal end extending through one of two leash openings,

each spool having a spool brake element and a return spring, a proximal end of the return spring being connected to the spool and a distal end of the return spring being connected to the axle, wherein when a force is applied to pull the leashes, the spools rotate thereby unwinding the return springs, and when the force is removed, the return springs rewind forcing the spool to rewind the leash to its original position;

a shaft having a proximal end and a distal end;

a brake rod having a distal end passing through the rod opening and the proximal end passing through the shaft;

a brake connected to the distal end of the brake rod, in a position engageable with said spool brake elements; and

a brake spring positioned on the brake rod between the brake and the axle, wherein the shaft rotation around the shaft axis and the spools'"'"' rotation around the axle axis is enabled when the brake is not engaged and disabled when the brake is engaged.

17. The device of claim 16, further comprising:

a housing for supporting the axle and the shaft;

a front panel including a first and second leash opening;

a handle attached to the proximal end of the shaft, the handle including a device for operating the brake rod; and

a bearing attached to the housing for rotatably supporting the shaft.

18. The device of claim 17, further comprising a locking device on said housing, engageable with a respective one of said spools for stopping rotation of said spool.

19. The device of claim 16, further comprising a housing, and a handle attached to the shaft, and a cowling portion at said handle for covering an area between said handle and said housing.

20. The device of claim 19, further comprising a locking device on said housing, engageable with a respective one of said spools for stopping rotation of said spool.
