Folding wrench cluster
First Claim
1. A folding wrench cluster, comprising:
- a single flat plate having a center, a first side, an opposite second side, a first edge, an opposite second edge, a first end, an opposite second end, and a longitudinal centerline;
a first wrench pivot pin extending through said first end of said plate adjacent said first edge thereof, and an opposite second wrench pivot pin extending through said second end of said plate adjacent said second edge thereof;
a first and a second wrench pivotally disposed upon said first wrench pivot pin respectively to said first side and to said second side of said plate, and a third and a fourth wrench pivotally disposed upon said second wrench pivot pin respectively to said first side and to said second side of said plate, with each said wrench having a longitudinal axis;
a first stop pin extending through said first end of said plate adjacent said second edge thereof, and an opposite second stop pin extending through said second end of said plate adjacent said first edge thereof; and
said first and said second stop pin each being disposed respectively adjacent said first and said second wrench pivot pin and farther from said center of said plate than said first and said second wrench pivot pin, for stopping arcuate motion of a corresponding said wrench when said corresponding said wrench is fully extended with the respective said longitudinal axis of said corresponding said wrench being substantially parallel to said longitudinal centerline of said plate.

Abstract
A folding wrench cluster may include at least four wrenches of different sizes and/or configurations, each selectively extendible from a single body portion. The body portion comprises a flat plate with a wrench secured to a pivot point extending from each side at each end of the body. The pivot points are laterally offset from the longitudinal centerline of the body. A laterally offset stop pin also extends from each side at each end of the body, with the stop pins being opposite the wrench pivot points. The stop pins are positioned to limit the arcuate motion of the wrenches when they are unfolded, so each wrench is closely aligned with the elongate body plate when it is fully extended, with the body plate serving as an extension handle. Spacers are provided between adjacent body plates or retaining members, to allow for a relatively thick wrench head for greater durability for the tool. The eye formed in the wrench handle for attachment to the pivot pin is also relatively heavy in order to absorb the shear stresses when torque is applied to the wrench and extended handle. Additional embodiments may include a plurality of plates each sandwiching two wrenches therebetween for further versatility, and a body plate having two wrench pivot points extending from each side at each end, with a stop pin disposed between each of the wrench pivot points on each side at each end, to effectively double the number of wrenches in a wrench cluster.

10. A folding wrench cluster, comprising:
-
a plurality of parallel, spaced apart flat plates including at least a first plate and a last plate; each of said plates having a center, a first side, an opposite second side, a first edge, an opposite second edge, a first end, an opposite second end, and a longitudinal centerline; a first wrench pivot pin extending through each said first end of said plates adjacent each said first edge thereof, and an opposite second wrench pivot pin extending through each said second end of said plates adjacent each said second edge thereof; a first group of wrenches each pivotally disposed upon said first wrench pivot pin, with said first group of wrenches including a first wrench disposed to said first side of said first plate, a last wrench disposed to said second side of said last plate, and an intermediate wrench disposed between each of said plates; a second group of wrenches each pivotally disposed upon said second wrench pivot pin, with said second group of wrenches including a first wrench disposed to said first side of said first plate, a last wrench disposed to said second side of said last plate, and an intermediate wrench disposed between each of said plates; each of said wrenches having a longitudinal axis; a first stop pin extending through each said first end of said plates adjacent each said second edge thereof, and an opposite second stop pin extending through each said second end of said plates adjacent each said first edge thereof; and said first and said second stop pin each being disposed respectively adjacent said first and said second wrench pivot pin and farther from said center of each of said plates than said first and said second wrench pivot pin, for stopping arcuate motion of a corresponding one of said wrenches when said corresponding one of said wrenches is fully extended with the respective said longitudinal axis of said corresponding one of said wrenches being substantially parallel to said longitudinal centerline of each of said plates. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
