Exercise tube with adjustable resistance

Description

THE BACKGROUND OF THE INVENTION

Many single exercise apparatus have only one fixed resistance strength. An exercise tube with adjustable resistance contains exchangeable spring loaded small tubes of different resistance strength. This allows the user to adjust the desired total compression resistance strength by inserting the correct spring loaded small tubes into the outer tubes of the exercise tube.

THE BRIEF SUMMARY OF THE INVENTION

An exercise tube with adjustable resistance can provide different compression resistance for exercise. A user selects the correct spring loaded small tubes of different resistance strength to add up to the desired total resistance strength and insert them into the bigger outer tubes. The user can adjust the resistances strength needed for a particular exercise. In addition, different users can share the same exercise tube by adjusting the resistance strength to suit their individual needs.

THE DETAILED DESCRIPTION OF THE INVENTION

Referring now in detail to the drawings numeral 11 of FIG. 1 is an exercise tube with adjustable resistance. Numeral 12 of FIG. 2 is components of exercise tube with adjustable resistance 11. Numeral 13 of FIG. 3 is the dissection view of exercise tube with adjustable resistance 11. Numeral 14 of FIG. 4 is the dissection view of components of exercise tube with adjustable resistance. Numeral 15 of FIGS. 1 and 2 is inner tube of exercise tube with adjustable resistance 11. Numeral 16 of FIGS. 1 and 2 is outer tube of exercise tube with adjustable resistance 11. Outer tube 16 can admit snuggly and easily inner tube 15. Inner tube 15 and outer tube 16 are preferable of the same length and overlap each other for about one quarter to one third of their lengths. Inner tube 15 can telescope and slide easily inside outer tube 16. Numeral 17 of FIGS. 1 and 2 is top cap of inner tube 15. Top cap 17 can admit inner tube 15 snugly and easily. Numeral 18 of FIGS. 1 and 2 is lower cap of outer tube 16. Lower cap 18 can admit snuggly and easily inner tube 16. Numeral 19 of FIGS. 1, 2, 3 and 4 is a rope. Numeral 20 of FIGS. 2, 3 and 4 is a ring. Numeral 21 of FIGS. 2, 3 and 4 is a hook. Hook 21 can hook onto ring 20. Numeral 22 of FIGS. 1 and 2 is a tunnel near the top end of top cap 17. Numeral 23 of FIGS. 3 and 4 is the dissected top cap 17. Numeral 24 of FIGS. 3 and 4 is dissected tunnel 22 of top cap 17. Numeral 25 of FIGS. 1 and 2 is a tunnel near top end of lower cap 18. Numeral 26 of FIGS. 3 and 4 is the dissected lower cap 18. Numeral 27 of FIGS. 3 and 4 is the dissected tunnel 25 of lower cap 18. Rope 19, ring 20 and hook 21 can pass through tunnels 24 and 27 easily. Numeral 28 of FIGS. 3 and 4 is the dissected inner tube 15 of FIGS. 1 and 2. Numeral 29 of FIGS. 3 and 4 is the dissected outer tube 16 of FIGS. 1 ans 2. Numeral 30 of FIG. 2 is spring loaded small tube. Numeral 31 of FIG. 2 is the inner tube of spring loaded small tube 30 of FIG. 2. Numeral 32 of FIG. 2 is outer tube of spring loaded small tube 30. Numeral 33 of FIGS. 3 and 4 is dissected inner tube of spring loaded small tube 31 of FIG. 2. Numeral 34 of FIGS. 3 and 4 is the dissected outer tube of spring loaded small tube 30 of FIG. 2. Inner tube 31 of spring loaded small tube 30 can telescope and slide snuggly and easily inside outer tube 32 of spring loaded small tube 30. Numeral 35 of FIGS. 3 and 4 is compression spring. Compression spring 35 is stored inside inner tube 31 and outer tube 32 of spring loaded small tube 30. Different compression spring 35 can have different resistance, such as 5 or 10 or 30 or more pounds of compression resistance. One inner tube 15 and one outer tube 16 of FIGS. 1 and 2 can store 4, 5 or more of spring loaded small tube 30 of FIG. 2. The more the spring loaded small tubes 30 are stored inside inner tube 15 and outer tube 16 the more force of resistance power will be produced for exercise. In addition to changing the number of spring loaded small tubes changing the type of spring loaded small tube 30 with different rresistance strength of compression spring 35 can also adjust the total resistance. The user can squeeze together the top cap 17 and lower cap 18 inwardly with both hands to train the pectorals. The user can grasp both sides of rope 19 and pull them sideway to train the dorsal muscles and deltoids. The user can use one foot or both feet to step on one side of rope 19 and use one hand or both hands to pull up another side of rope 19 to train the biceps, back muscles and quadriceps. The user can push exercise tube with adjustable resistance 11 against the wall with the abdomen to train abdominal muscles.
