Ergonomic cable tie installation tool

An ergonomic cable tie installation tool includes a generally pistol-shaped housing including a grip which depends from a barrel. Pivotally connected to the lower region of the grip is a trigger linkage of a trigger mechanism. The trigger mechanism also includes an intermediate linkage pivotally connected to the trigger linkage. The intermediate linkage is supported in the housing. The intermediate linkage is, in turn, connected to a tensioning mechanism also supported in the housing. The tensioning mechanism couples the intermediate linkage to the cable tie. Pivoting the trigger linkage toward the grip, normally by the hand of a user, causes the intermediate linkage to pivot resulting in the tensioning mechanism producing an increased tension in the cable tie. The trigger linkage is oriented relative to the grip such that pivoting it toward the grip requires the stronger fingers of the user's hand to travel more than the weaker fingers thereby improving the ergonomics of the tool. The trigger linkage may also make the respective travel distances of the stronger and weaker fingers more uniform also improving the ergonomics of the cable tie installation tool. Moreover, the trigger mechanism may provide for the tension force applied to the cable tie to increase as the trigger linkage is increasingly pivoted toward the closed position. Methods of operating the tool also provide improved ergonomics of the tool.

Tool for removing nail polish and buffing nails

A nail care tool having an ergonomic elongated handle and a removable operational head attached to the handle is presented. The tool also has a removable scraper or end tip inserted in one of the ends of the handle, useful in cleaning critical cuticle areas. The operational head has adhered to it a lining of material commonly used in the nail care and maintenance processes; for instance, it may be a nail polish removal material or a nail buffing material. In some embodiments of the invention, the ergonomic handle and the head are interconnected in a nonpermanent manner by a male/female system; in such embodiments, the head may be engage or connected to the handle by screwing the head to the handle and, it may be disengaged or disconnected, by simply unscrewing it from the handle. In other embodiments of the invention, the handle is connected to the head by a hold/release system, allowing the User to connect the head and the handle by inserting an already assembled cartridge inside the handle into a rectangular internal cavity on the head. In order to disconnect the head from the handle, the User slides backwardly a button on the ergonomic handle without even having to touch the head. The hold/release system allows the User to easily attach or detach heads to the handle. The operational removable head required for any of the embodiments may have different shapes and operational lining materials, in order for the User to use the tool as an applicator—meaning being able to remove most of the nail polishes—or as a nail buffer.
