Abstract

Some difficulty exists in providing a force output of a flat rate or increased force from a spring (tension, compression, leaf, torsion, clock and other) as the spring expends its energy. The mechanism described provides an equal or increasing output force from a decreasing spring input force. A toggle mechanism (which provides the output force) is combined with a spring or combination of springs, levers, links, etc. that provide the input force. A simplified version is shown in the drawing. It would be used in conjunction with a manual or machine energizing device.

Toggle Spring Pressurizing Mechanism

Some difficulty exists in providing a force output of a flat rate or increased force from a spring (tension, compression, leaf, torsion, clock and other) as the spring expends its energy. The mechanism described provides an equal or increasing output force from a decreasing spring input force. A toggle mechanism (which provides the output force) is combined with a spring or combination of springs, levers, links, etc. that provide the input force. A simplified version is shown in the drawing. It would be used in conjunction with a manual or machine energizing device.

In the drawing, as spring B contracts or spring C expands the resultant force F on pin A will decrease. However, due to the mechanics of a toggle joint, as connecting pin A moves to the right and angle Alpha approaches zero (0), the output force P will increase.
