Patent ID: 7331261

Claim:
A crosswise wrench comprising: an extended element defining a longitudinal axis and having first and second ends with heads on the first and second ends; a prismatic core with a polygonal cross-section with a face plate nut head on one end of the core and a working point on another end of the core, the core including at least three fixing recesses, including a first fixing recess located in the middle of the core, and the two other fixing recesses located at an equal distance in relation to the first recess, wherein the fixing recesses are circular grooves, the extended element has at least three identical pairs of partially mutually transverse apertures with mutually perpendicular axes, that cross the longitudinal axis of the extended element at a right angle, the first apertures of each pair of the partially mutually transverse apertures are through and have the same polygonal shaped cross-section as the prismatic core and wherein the sizes ensure its sequential placement in said apertures providing for selective longitudinal movement, wherein one first aperture is located in the middle of the extended element and the other two first apertures are located at an equal distance in relation thereto, wherein a lateral surface edge of the first aperture, crossed by the corresponding second aperture in each pair of the partially mutually transverse apertures is located in a diametrical plane of the extended element perpendicular to the axes of the second apertures.
