Abstract

A locking device that prevents a rooftop support device from being separated into upper and lower parts is disclosed. The locking device stops the lower base from being fully unscrewed from the upper platform. The device automatically releases to allow the lower base to be screwed back onto the upper platform.

Claims (19)

1. A rooftop support locking device for preventing a lower base of a rooftop support from being separated from an upper platform comprising:

a resilient material mounted to said lower base, said resilient material having a lock body disposed at a first end, an opposite end disposed at a second end of said resilient material, a pivot point disposed on said resilient material between said first end and said second end of said resilient material,

said lock body engages with a lock slot located in said upper platform,

and said resilient material also having a marked release button disposed on said resilient material between said pivot point and said opposite end for disengaging the lock body from the lock slot,

and said pivot point having an axle for mounting said resilient material to said lower base,

wherein said resilient material has a generally linear shape from said pivot point to said opposite end when not engaged with said lock slot and a generally curved shape from said pivot point to said opposite end when engaged with said lock slot.

2. The device of claim 1 wherein such locking device automatically disengages the lock body from said lock slot when said lower base screws back into said upper base.

3. The device of claim 1 wherein said locking device is made of plastic.

4. The device of claim 1 wherein said locking device is mounted into a recessed section of said lower base of said rooftop support such that said locking device can pivot about said pivot point.

5. The device of claim 1 wherein said axle comprises a part of said locking device at said pivot point that extends into the lower base.

6. The device of claim 1 , wherein said marked release button for disengaging the lock body from the lock slot is shaped to be easily pressed.

7. The device of claim 1 , wherein said axle comprises a bolt that runs through said pivot point.

8. A rooftop support locking device for preventing a lower base of a rooftop support from being separated from an upper platform comprising a resilient material located on said lower base having a lock pin at a first end, an opposite end disposed at a second end, and a pivot point disposed between said first end and said second end, said lock pin configured to engage with a lock slot in said upper platform of said rooftop support, and said resilient material also having a marked release button disposed on said resilient material between said pivot point and said opposite end for disengaging the lock pin from the lock slot and also having an axle at said pivot point for mounting said resilient material to said lower base, wherein said resilient material has a generally linear shape from said pivot point to said opposite end when not engaged with said lock slot and a generally curved shape from said pivot point to said opposite end when engaged with said lock slot.

9. The device of claim 8 wherein such locking device automatically disengages the lock pin from said lock slot when said lower base is rotated toward said upper platform.

10. The device of claim 8 wherein said locking device is made of plastic.

11. The device of claim 8 wherein said locking device is mounted into a recessed section of said lower base of said rooftop support such that said locking device pivots about said pivot point.

12. The device of claim 8 wherein said axle comprises a part of said locking device at said pivot point that extends into the lower base.

13. The device of claim 8 , wherein said marked release button for disengaging the lock pin from the lock slot is shaped to be easily pressed.

14. The device of claim 8 , wherein said axle comprises a bolt that runs through said pivot point.
