Abstract

A trampoline has a frame, legs, a bed, springs, an upper spring cover, and a lower spring cover. The frame is horizontally oriented. The legs attach to the frame and support the frame. The bed is suspended across the frame. The springs are in tension and stretch the bed across the frame. The upper spring cover covers the springs from the frame to the bed and a lower spring cover. The lower spring cover attaches to the upper spring cover at a pad to sheath connection. The pad to sheath connection is on the lower distal end of the upper spring cover. The lower spring cover wraps around a horizontal frame portion of the frame around an outside portion of the horizontal frame portion of the frame.

First claim

The invention claimed is:

1. A trampoline:
a. a frame, wherein the frame is horizontally oriented;
b. legs, wherein the legs attach to the frame, and wherein the legs support the frame;
c. a bed, wherein the bed is suspended across the frame;
d. springs connecting the frame to the bed, wherein the springs are in tension and stretch the bed across the frame;
e. an upper spring cover, wherein the upper spring cover covers the springs from the frame to the bed, wherein the upper spring cover covers the upper side of the springs; and
f. a lower spring cover, wherein the lower spring cover is underneath the springs and covers a lower side of the springs, wherein the upper spring cover includes a pad, wherein the lower spring cover attaches to the upper spring cover at a pad to sheath connection.

2. The trampoline of claim 1 , wherein the pad to sheath connection is on the lower distal end of the upper spring cover.

3. The trampoline of claim 2 , wherein the lower spring cover wraps around a horizontal frame portion of the frame around an outside portion of the horizontal frame portion of the frame.

4. The trampoline of claim 3 , wherein the springs are helical springs having a spring body with a proximal hook engaging a connector link on the bed, and wherein the springs have a distal hook engaging a frame hollow portion of the frame, wherein the distal hook has a distal hook end that inserts into the hollow frame portion.

5. The trampoline of claim 4 , wherein the spring body has a proximal extension extending toward the bed and a distal extension extending toward the frame, wherein the proximal extension bends downwardly to a proximal bend, and wherein the distal extension bends downwardly to pass through a spring connection opening formed on the frame.

6. The trampoline of claim 5 , wherein the proximal bend terminates at a hook end cover.

7. The trampoline of claim 6 , wherein the proximal bend bends upwardly to an upward extending hook.

8. The trampoline of claim 7 , wherein the proximal bend bends back toward the frame at a proximal bend back.

9. The trampoline of claim 8 , wherein the proximal bend back terminates at a proximal hook end that forms a spring biased gate with a spring body barrel edge.

10. A trampoline:
a. a frame, wherein the frame is horizontally oriented;
b. legs, wherein the legs attach to the frame, and wherein the legs support the frame;
c. a bed, wherein the bed is suspended across the frame;
d. springs connecting the frame to the bed, wherein the springs are in tension and stretch the bed across the frame;
e. an upper spring cover, wherein the upper spring cover covers the springs from the frame to the bed, wherein the upper spring cover covers the upper side of the springs; and
f. a lower spring cover, wherein the lower spring cover is mounted underneath the springs and completely covers a lower side of the springs all the way from the frame to the bed, wherein the bed is smaller than the frame such that a gap is formed between the bed and the frame.

11. The trampoline of claim 10 , wherein the springs are helical springs having a spring body with a proximal hook engaging a connector link on the bed, and wherein the springs have a distal hook engaging a frame hollow portion of the frame, wherein the distal hook has a distal hook end the inserts into the hollow frame portion.

12. The trampoline of claim 11 , wherein the springs have a spring body with a proximal extension extending toward the bed and a distal extension extending toward the frame, wherein the proximal extension bends downwardly to a proximal bend, and wherein the distal extension bends downwardly to pass through a spring connection opening formed on the frame.

13. The trampoline of claim 12 , wherein the proximal bend terminates at a hook end cover.

14. The trampoline of claim 13 , wherein the proximal bend bends back toward the frame at a proximal bend back.

15. The trampoline of claim 14 , wherein the proximal bend back terminates at a proximal hook end that forms a spring biased gate with a spring body barrel edge.

16. The trampoline of claim 13 , wherein the proximal bend bends upwardly to an upward extending hook.

17. The trampoline of claim 11 , wherein the lower spring cover is formed as a sheath with a sheath upper part and a sheath lower part, wherein the sheath upper part and the sheath lower part meet at a sheath opening edge, wherein the lower spring cover encapsulates the connector link and the proximal hook, wherein the proximal hook further includes a proximal hook end.

18. The trampoline of claim 17 , further including a loop swivel opening, wherein the connector link is mounted to a loop swivel, wherein the loop swivel is mounted to the bed.

19. The trampoline of claim 11 , wherein the lower spring cover attaches between the bed and the springs, wherein the lower spring cover attaches to the bed at sheath inside attachment which is the connection between a sheath upper edge and the bed, and wherein the lower spring cover attaches to the springs at a sheath lower edge at a sheath outside attachment.
