Abstract
Hand tools which have an ergonomic using a palm handle and finger handle designs which achieve mechanical efficiency and ease of use. The ergonomic handle is compatible with the muscle movements of an operator using a hand tool reducing muscle strain and pain. Optionally, the palm and finger handles can have ergonomically designed cushions. In an embodiment, the finger handle can have a finger set which has a forward finger flange, a tail finger flange and a pinky grip. The ergonomic handle can also use a relief washer system to achieve a smooth low frictional resistance cutting stroke.
Claims26
A handle for a metal snips hand tool, comprising:
- a palm handle for the metal snips hand tool pivotally connected to a finger handle;
- said palm handle adapted to pivotally connect to at least a first portion of a nosepiece of the hand tool;
- said palm handle having an extended palm grip purlicue width that is greater than a palm handle narrow width;
- said palm handle having a purlicue base having a purlicue base height in a range of about 14 mm to about 21 mm;
- said palm handle having a purlicue curve radius in a range of 7.5 mm to 35 mm;
- said finger handle having an extended finger grip configured to receive a grip of an index finger of an operator and a finger set having a finger trough configured to receive a grip of a middle finger of an operator, said finger trough configured between a forward finger flange and a tail finger flange;
- said forward finger flange having a concave portion between the extended finger grip and a forward finger flange peak, such that the forward finger flange extends between the index finger and the middle finger of the operator when the grip of the middle finger of the operator is received in the finger trough;
- said finger trough having a trough base height in a range of about 19 mm to about 28 mm;
- said finger handle adapted to pivotally connect to at least a second portion of said nosepiece;
- and
- said handle having closed state and an open state.
The handle for a metal snips hand tool according to claim wherein said palm handle having a purlicue curve radius in a range of 7.5 mm to 35 mm.
The handle for a metal snips hand tool according to claim further comprising an extended finger flange diameter in a range of 12 mm to 40 mm.
A handle for a metal snips hand tool, comprising:
- a palm handle for the metal snips hand tool pivotally connected to a finger handle;
- said palm handle adapted to pivotally connect to at least a first portion of a nosepiece of the hand tool;
- said finger handle having an extended finger grip configured to receive a grip of an index finger of an operator and a finger set having a finger trough configured to receive a grip of a middle finger of an operator, said finger trough configured between a forward finger flange and a tail finger flange;
- said finger handle having a forward finger flange width that is greater than a finger flange width;
- said extended finger grip having an extended finger grip base height in a range of about 20 mm to about 29 mm;
- said forward finger flange having an extended finger flange radius in a range of 6 mm to 20 mm;
- said forward finger flange having a concave portion between the extended finger grip and a forward finger flange peak, such that the forward finger flange extends between the index finger and the middle finger of the operator when the grip of the middle finger of the operator is received in the finger trough;
- said finger handle adapted to pivotally connect to at least a second portion of said nosepiece;
- and
- said handle having closed state and an open state.
A handle for a hand tool, comprising:
- a palm handle pivotally connected to a finger handle;
- said palm handle adapted to pivotally connect to at least a first portion of a nosepiece of the hand tool;
- said palm handle having a partial torus shape and a purlicue base having a purlicue base height in a range of about 14 mm to about 21 mm;
- said finger handle having an extended finger grip configured to receive a grip of an index finger of an operator and a finger set having a finger trough configured to receive a grip of a middle finger of an operator, said finger trough configured between a forward finger flange and a tail finger flange;
- said forward finger flange having a concave portion between the extended finger grip and a forward finger flange peak, such that the forward finger flange extends between the index finger and the middle finger of the operator when the grip of the middle finger of the operator is received in the finger trough;
- said finger trough having a trough base height in a range of about 19 mm to about 28 mm;
- said finger handle adapted to pivotally connect to at least a second portion of said nosepiece;
- and
- said handle having closed state and an open state.
