Abstract
An adjustable tension spring anchor with rotatable head. A flanged head is rotatably mounted to a threaded cylinder mounted to a first element. The rotatable head is connectable to one end of a tension spring having its opposite end attached to a second element. A pair of mutually opposed flat surfaces on the cylinder and a socket at the end of the cylinder allows the cylinder to be rotated to adjust tension without twisting of the attached spring.
Claims18
A swivel anchor for adjusting the tension on a spring comprising:
- a head connectable to a spring;
- and,
- an elongated cylindrical main body with a longitudinally axis and having a first end and a second end, said first end having said head movably mounted thereon to allow said head and attachable spring to remain rotatably stationary while said main body is rotated about said axis to change the tension in the spring or to allow said main body to remain stationary while said head and attachable spring are rotated about said axis to change the tension in the spring.
A spring anchor for changing the tension in a spring comprising:
- an elongated cylindrical main body with a first end and opposite second end and a longitudinal axis extending therebetween, said main body includes a first threaded surface;
- and,
- a mounting head rotatably mounted to said first end of said main body and having first engageable means to receive and hold one end of a spring, said main body being rotatable about said axis on said threaded surface to move said head longitudinally along said axis and change the tension in the spring.
The combination extendable between a first support and a second support spaced apart from the first support of:
- a helical spring with a spring first end and a spring second end with a spring axis extending therebetween, said first end mountable to a first support with said spring extendable toward a second support;
- and,
- a main body having a main body first end and a main body second end with a main body axis extending therebetween, said main body first end mountable to the second support with said main body axis being alignable with said spring axis, said main body further having a head rotatably mounted to said main body first end and attachable to said spring second end, said main body or said spring being rotatable about said main body axis and said spring axis to change tension in said spring.
