Abstract: The device for manually rotating at least one rotatable element, particularly an element of a jack, possesses a handle, a pivot and a coupling member. The handle has two arms. The handle and the pivot consist of a one-piece rod or of two rods which were initially separate and have then been rigidly and nondetachably connected at adjacent ends. The pivot penetrates the coupling member and connects the latter pivotably to the handle. The two arms have contacting portions which contact one another and are secured to one another by spot weld joints. One of the arms has an end portion shaped to serve for removing hub caps. The handle and pivot are manufactured from a straight rod or two straight rods having a circular cross-section by non-cutting shaping. The device can be manufactured and assembled quickly and at low costs and enables to transmit large torques.

Abstract: A door lock assembly of the type for use with sliding doors, windows or the like for securing a moveable member relative to a stationary member, the assembly including an elongated bar member adapted to be attached at one end to a support frame mounting the moveable and stationary members and having at its opposite end a selectively operable latch mechanism adapted to coact with the moveable member so as to selectively lock and unlock such moveable member relative to the stationary member.
