| A key ring and screwdriver device is disclosed as including a hollow tubular handle having opposite open ends. A reversible screwdriver having different blade ends at an intermediate polygonal cross sectional area is capable of being stored in one open end of the hollow tubular handle. At the opposite open end of the hollow tubular handle, a ferrule is provided. The ferrule includes an outer internally threaded section and inner polygonally shaped section. The outer internally threaded section has a cross sectional dimension greater than the reversible screwdriver blade in order to freely accommodate same. The inner polygonally shaped section has a complementary shape and size for receiving the intermediate polygonal cross sectional area of the reversible screwdriver blade in driving engagement therewith. At least one key ring is provided which has a threaded end for complementary threaded engagement with the outer threaded section of the ferrule element when the screwdriver blade is stored in the opposite open end of the hollow tubular handle. A second key ring may also be provided with a threaded end for complementary threaded engagement with an internally threaded area on the opposite open end of the hollow tubular handle, in order to capture the screwdriver blade in the hollow tubular handle. | ||||||
| 42 | Plate block key ring | US750247 | 1991-08-27 | US5154073A | 1992-10-13 | Yu-Hwei Huang |
| The present invention relates to a plate block key ring, wherein several plate blocks are combined with a swivel shaft, so as to be enable the blocks to rotate. These plate blocks have peripheral rails to form key ring outlets that allow keys to be readily attached to and detached from the ring.

| 43 | Key ring | US470765 | 1990-01-26 | US5031430A | 1991-07-16 | Linden D. Nelson |
| A double ended key ring includes a first body portion, a second body portion, and joining and biasing mechanisms for releasably engaging the first and second body portions together to form a key ring having openings on opposite ends. The first body portion is configured to form one of the openings and has a gap which is hidden when the first and second body portions are biased together in an engaged position. The first and second body portions can be moved axially and then rotated into an open position to expose the gap. In an alternate embodiment, the joining mechanism may be pushed from the second body portion toward the first body portion thereby disengaging the body portions from the engaged position. | ||||||

| A double ended key ring includes a housing and a cover which are pivotally connected. A bias mechanism urges the housing and cover into an open position thereby providing access to an opening therebetween for mounting or removing keys or keyholders. A latch mechanism is pivotally mounted relative to the housing for releasably holding the cover in the closed position. The entire bias mechanism and the latch mechanism is effectively concealed when the key ring is in the engaged or closed position, in which position the removal of keyholders is precluded. | ||||||

| A key ring including a continuous loop of material including a first section extending for the majority of the circumference of the continuous loop of material having a thickness of D1, and a indented second section extending for the remainder of the circumference of the continuous loop having a thickness D2 less than D1. The key ring also includes a securing device slidable about the continuous loop to cover and uncover the indented second section. One or more spring clips including a moveable arm having a tip end and a fixed member to which the movable arm is attached, the moveable arm moving between an opened position and a closed position, wherein a distance D3 is provided between the tip end of the moveable arm and a hook end of the fixed member when the moveable arm is in the opened position abutting the fixed member. The distance D3 is greater than D2, and less than D1 thus only allowing the spring clip to be attached and removed from the key ring at the indented second section of the continuous loop of material. The spring clip includes a split key ring. | ||||||

| 56 | Pull-apart key holder | US92697 | 1998-06-05 | US5927116A | 1999-07-27 | Michael J. Emoff |
| A key holder comprises a pair of key rings each connected to a fob, and the fobs can be releasably secured to one another. The fobs are configured as conventional male and female electrical connector plugs, such as conventional blade-type electrical connector plugs. The plugs are miniaturized to prevent connection to an actual current-carrying outlet or plug. In a second embodiment, the fobs are configured as fractional portions of a sport's game piece, such as a baseball, and create the appearance of the sport's game piece when secured together. | ||||||
| 57 | Fast assembled twin ear key rings | US790404 | 1997-01-29 | US5755127A | 1998-05-26 | Yu-Hwei Huang |
| An easily assembled twin ear style key ring. The main body thereof is comprised of two casing halves, i.e., the front casing and the rear casing. A hollow stub on one of the casings extends through a hole provided on the other casing to quickly join the two casings together. The ends of the puller pins are inserted into positioning bushings having slightly larger diameters than the puller pins. The bushings are fixed in the main body by the front and the rear casings when the casings are pressed together. Manufacturing of the twin ear key rings is therefore faster than prior art devices, and is favorable to mass production. | ||||||
