In another further embodiment, the second lock plate is situated below the release plate and the spring holding compartments, the central opening and the cutouts are aligned relative to the two lock plates and the release plate. In yet another further embodiment, the release plate is sandwiched between the two lock plates.
In still another further embodiment, the opposing walls have an enhanced gripping surface. In still yet another further embodiment, the back surface of the recess is formed by a second cover plate.
In another embodiment, the angled locking surface of the cutouts has an enhanced gripping surface. In yet another embodiment, the sidewalls of the recess are made of an insert of hardened metal.
In still another embodiment, the present invention relates to a slide lock mechanism designed to work with a tool, and the tool comprises a body with a recess and a head with an opening and a handle, and the mechanism comprises: at least one lock plate, at least one release plate and at least two rollers, each of the lock and release plates comprising at least one spring holding compartment, at least one central opening and at least two cutouts, and the mechanism having a contact element, at least a portion of the contact element contacting a portion of the lock plate, the lock plate is situated above the release plate and the openings and cutouts of each of the plates are aligned with one another and inserted with the recess of the body, the mechanism further comprising at least two rollers and at least one spring, at least a portion of each of the rollers are situated within the cutouts of the plates, at least a portion of the spring is situated within the spring holding compartment of the plates, the spring causes the rollers to engage the opposing walls of the recess of the body, the mechanism further comprises at least one button having a top contact surface and a bottom protrusion, at least a portion of the protrusion is designed to be situated within the central openings of the release and lock plates, whereby the slide lock mechanism functions based on movement of the button, the button has two positions, a first operating position and a second non-operating position, when the button is in a non-operating position the rollers are urged against the angled locking surface of the cutouts thereby wedging the rollers against the sidewalls of the recess preventing the contact element from moving towards the handle.
In a further embodiment, the present invention provides for a slide lock mechanism designed to work with a toll, the tool comprising a body with a recess and a head with an opening and a handle, the mechanism comprising: at least one lock plate, at least one release plate and at least two rollers, each of the lock and release plates comprising at least one spring holding compartment, at least one central opening and at least two cutouts, the lock plate having a contact element, the lock plate is situated above the release plate and the openings and cutouts of each of the plates are aligned with one another and inserted with the recess of the body, the mechanism further comprising at least two rollers and at least one spring, at least a portion of each of the rollers are situated within the cutouts of the plates, at least a portion of the spring is situated within the spring holding compartment of the plates, the spring causes the rollers to engage the opposing walls of the recess of the body, the mechanism further comprises at least one button having a top contact surface and a bottom protrusion, at least a portion of the protrusion is designed to be situated within the central openings of the release and lock plates, whereby the slide lock mechanism functions based on movement of the button, the button has two positions, a first operating position and a second non-operating position, when the button is in a non-operating position the rollers are urged against the angled locking surface of the cutouts thereby wedging the rollers against the sidewalls of the recess preventing the contact element from moving towards the handle.
In another further embodiment, the mechanism further comprises a tool having a body with at least one recess and a head with at least one opening and at least one handle.
