This invention relates to clips in general and specifically to money clips with retractable levers as shown in U.S. Pat. Nos. 5,946,778, 6,988,296, D552,008 and D592,987. Money clips as disclosed and claimed in these patents have been well received by the public but have certain drawbacks related to them being constructed of multiple parts which require precise machining detailed assembly or other appropriate manufacturing processes.
A clip, and especially a money clip, includes operating levers which extend outwardly for the purpose of opening the clip and which retract inwardly in a compact fashion. The clip includes a spring comprising a pair of jaws biased inwardly with a pair of slots formed on the outer surface of each jaw for the purpose of receiving the operating levers. A spring pocket is formed on the outer surface of each jaw to receive a spring tab. The spring tab comprises a base with an upwardly extending stop tab disposed in an elongated slot formed on the inside surface of the respective lever for the purpose of preventing withdrawal of the operating levers from the clip.
In the drawings:
The clip, according to this invention, is constructed of a single piece of material that initially is flat and is then shaped by various methods of production to include top, front and side edges that are made as integral elements of the spring itself. Spring 1 is produced from any material that can be shaped and formed as needed such as heat treated metal, plastic, carbon composites, etc. The clip is shaped, sized, configured and designed to accommodate the desired effect for the particular function and design for which it is intended, i.e., money clips, paper clamps, bag clips, etc. Spring 1 includes jaws 1a and 1b extending from curved throat 2. Spring 1 may include one or more separate additional bends 3 to allow increased flex in the overall opening and closing action of the spring.
Bosses 4 are integrally formed on the outer surfaces of jaws 1a and 1b of spring 1. The inner edges of boss 4 are shaped to include spaced slots 5 and 6 in which separate and independent operating levers 7 and 8 are received which are designed and made to slide within slots 5 and 6 of bosses 4. The bosses act as receivers which allow operating levers 7 and 8 to move within slots 5 and 6.
Operating levers 7 and 8 are designed with runner edges that are inserted into slots 5 and on spring 1 to allow them to be guided back and forth into a closed or extended position. These runners on the side edge of each operating lever 7 and 8 are designed with edges which are offset from the main operating lever planar base element and which function as sliding points or rails 9 which are used to allow minimal contact with spring 1, ultimately resulting in minimal friction contact points and improved sliding action. Also, operation levers 7 and 8 are designed and made to allow the insertion or application of various materials to adorn the top, bottom or sides to produce a desirable cosmetic affect and appeal for the marketplace.
The clip includes at least one specially designed spring tab stop mechanism 10 on each side of the clip that is disposed under the operating levers 7 and 8. Spring tab 10 is mounted temporarily or permanently in spring pocket 10a formed in each of the outer surfaces of jaws 1a and 1b. The shape and size of spring tab 10 is designed to conform to the shape and size of spring pocket 10a which could be square, rectangular, triangular or any other suitable configuration. Spring tab 10 functions as a stop mechanism for operating levers 7 and 8 to prevent them from sliding out of spring 1 and to limit the extension of each lever to its desired maximum.
Resilient stop tab 11 of spring tab 10 applies tension to operating levers 7 and 8 to create the proper sliding action and feel required for the clip as a result of pressing upward into elongated slot 12 formed in the underside of each operating lever 7 and 8. Specifically, upstanding stop tab 11 is joined to base 10b of spring tab 10 along bend line 10c with bend line 10d formed generally midway of tab 11.
In operation, as operating levers 7 and 8 are withdrawn outwardly of the clip, stop tabs 11 are caused to slide in slots 12 until such time that the outer rounded tips of stop tabs 11 engage the respective ends of slots 12 thereby preventing any further withdrawal of operating levers 7 and 8.
The underside of spring 1 includes one or more added grip pads 13. Additionally, particular markings, etchings or grip marks may also be formed on the underside of each side of spring 1 to separate the grip pads.
The benefits under 35 U.S.C. 119 are claimed of provisional patent application 61/337,958 filed Feb. 12, 2010.
