Abstract

PROBLEM TO BE SOLVED: To transmit the torque of a lock driver to a screw enough to surely lock the screw without breaking the groove(s) of a screw head. SOLUTION: In this lock screw 1, a minus groove or plus grooves such as a groove(s) formed on the screw head section 2 of a bolt or a wood screw is formed into a shape of a dovetail groove 3. In this case, a recessed section 7 for positioning is formed in the center section of the dovetail groove 3. A lock driver 4 has a tip section 9 which broadens toward the tip having nearly the same shape as that of the dovetail groove 3. A projected section 8 for positioning is formed in the center section of the tip broadened section 9.

In the lock screw 1 of the first embodiment, a wide portion 5 having a wide bottom portion is formed on a head portion 2 and a narrow portion 6 having a narrow upper portion is formed on a head portion 2 to form a dovetail groove 3. The lock screw 1 is formed by inserting a lock driver 4 into a dovetail groove 3 formed in the head 2 and screwing it. As shown, the dovetail groove 3 has a wide portion 5 at the bottom and a narrow portion 6 at the top. The wide portion 11 at the tip of the lock driver 4 is approximately the same width as the narrow portion 6 at the top of the dovetail groove 3 against the wood screw, but the wedge function is achieved by slightly turning the lock driver 4 slightly. Since the lock state is set, the driver does not run idle and the dovetail groove 3 is not broken.

Further, a concave portion 7 for positioning is formed at the center of the bottom of the dovetail groove 3 so that a convex portion 8 formed at the tip of the lock driver 4 is engaged with the lock driver 4.
And the dovetail groove 3 formed in the head 2 of the screw can function in the best condition against the application of the most force, and the tip of the lock driver 4 is increasingly disengaged from the dovetail groove 3 of the screw. Will not be crushed or destroyed.

Next, the lock driver 4 is shown in FIG.
This will be described with reference to FIG. The lock driver 4 is formed of a handle 10 for gripping and a tip 9 made of a hardened steel material at the lower part thereof, and the tip 9 is substantially the same as the narrow part 6 above the dovetail groove 3 of the lock screw 1. A wide portion 11 having a wide width is formed, and a narrow portion 12 is formed which is inclined by a length corresponding to the depth of the dovetail groove 3 which becomes narrower toward the handle 10. By simply inserting this tip 9 into the dovetail groove 3 of the lock screw 1 and turning it one dimension, the tip 9 of the lock driver 4 is locked in the dovetail groove 3 of the lock screw 1 in a wedge-like manner. Further, the screw can be loosened, and the lock driver 4 does not come off from the groove, so that the dovetail groove 3 is not crushed or broken.

Further, since the convex portion 8 is formed at the center of the wide portion 11 of the distal end portion 9 of the lock driver 4, it is engaged with the concave portion 7 at the bottom center of the dovetail groove 3 of the lock screw 1 for positioning. When the force of the lock driver 4 is applied, it works reliably and very effectively.
