Abstract

An accessory for a hand drill which cooperates with the crank handle of the opening mechanism of a casement window. The accessory, when turned by the drill, facilitates turning of the crank handle and opening or closing of the window. The accessory includes a shaft which is intended to be gripped by the chuck or jaws of the hand drill in much the same manner that hand drills grip drill bits. A forwardly projecting crank handle-contacting head is provided which is adapted to slide over the crank handle. The head has a side opening with a pair of edges which push against one side of the crank handle in order to rotate the same. Preferably, the inside surface of the head of the accessory and the crank handle'"'"'s contacting edges are rubber coated so that rotation of the accessory and its movement with respect to the crank handle will not mar the finish of the crank handle. In an alternate embodiment, the head can be adapted for rotation of the splines of the window turning mechanism exposed when the handle is fully removed. In yet another alternate embodiment, a head is provided which is adjustably configured to receive different sized crank handles.

Claims

1. An accessory for a hand drill for facilitating turning of a crank handle of the opening mechanism for a casement-type window, the crank handle having a cylindrical connection portion and a lateral extension connected thereto, said lateral extension being smaller in width than the diameter of said cylindrical connection portion the accessory comprising:

(a) a hand drill connection means for removably connecting the accessory to a hand drill and for transmitting the torque power of said hand drill to said accessory and;

(b) a head end connected to said hand drill connection means adapted to contact and rotate said crank handle when said hand drill connection means is rotated by said hand drill;

said head end being provided with a central cavity having a laterally extending opening, said central cavity adapted to fit over said cylindrical connection portion and said laterally extending opening being wide enough to allow said lateral extension of said crank handle to pass therethrough, and said laterally extending opening being at least as wide as said cylindrical connection portion of said crank handle.

2. An accessory as claimed in claim 1 wherein said hand drill connection means is hex-shaped shank.

3. An accessory as claimed in claim 1 wherein said lateral extension of said crank handle defines an angular orientation with respect to a center axis passing through said cylindrical connection portion and said central opening further comprises an inclined section matingly configured to the angular orientation and dimensions of said lateral extension of said crank handle.

4. An accessory as claimed in claim 1 wherein said lateral opening defines a pair of edges, said edges being rubber coated.

5. An accessory as claimed in claim 1, wherein said central opening is rubber coated.
