  "abstract": "The present invention relates to an adjustable paper clip which facilitates the user to grip desired size of paper bundle. The user makes adjustments in the first element of an adjustable paper clip to enable the user to open it at a required distance for gripping the desired size of paper bundle.",
  "claims": [
    "1. A user adjustable paper clip, configured to grip a paper bundle, comprising: a. a first curved element, further comprising a handle and a plurality of male members, wherein a single male member further comprises a first end, a second curved end, and a plurality of gears, such that the first end of the single male member is integrally connected to the first curved element; and b. a second curved element, further comprising a handle and a plurality of female members at a first end of the second curved element, wherein the plurality of female members is configured to slide onto the plurality of male members correspondingly, so as to adjust the distance between the first end of the single male member integrally connected to the first curved element and the first end of the second curved element in accordance with the desired size of the paper bundle; and pressure exerted by the second curved end of the single male member on a single female member respectively ensures that the first curved element and the second curved element do not separate.",
    "2. The user adjustable paper clip of claim 1, wherein the first curved element and the second curved element are made up of plastic or any combination of plastic and steel.",
    "3. The user adjustable paper clip of claim 1, wherein the breadth of the second curved end of the single male member of the first curved element is greater than the breadth of the single female member of the second curved element so as to keep the first curved element and the second curved element together and prevent separation.",
    "4. The user adjustable paper clip of any of the claims 1 - 3, wherein the plurality of gears of the single male member of the first curved element is equal to three.",
    "5. The user adjustable paper clip of any of the claim 1 - 3, wherein the plurality of male members and the plurality of female members is equal to three."

  "description_excerpt": "Presently there are varieties of clamping devices available to grip paper bundle such as staplers, clip board pins, paper clips and the like. It is often observed that, the use of staplers and clipboard pins causes damage to the paper and thus put impression of pins or staplers on it which is highly undesirable. Also, the staplers have a limitation as they are restricted to staple a limited size of paper bundle. In such case, bigger stapler is desired in order to staple a bigger size of paper bundle which is undesirable for the user.\n\nThe other extensively used clamping device is a paper clip and is available in the two most pervasive forms. One, it is available as a loop of wire with a single loop facing in one direction and a pair of nesting loops facing in the other direction and two, as a two steel wires attached to a steel strip at their front end making an isometric triangle for griping the paper bundle. However, the limitations with these conventional paper clips are their sizes which enable them to grip a limited size of paper bundle. The user has to purchase a bigger size of paper clip to grip bigger paper bundle. Thus, the user has to buy different variants of paper clips in accordance with the size of paper bundle which is highly undesirable.\n\nIn prior art U.S. Pat. No. 4,920,614, the inventor proposes a plastic paper clip which is adjusted by sliding the clamping plate on it. However, the drawback of this invention is the clamping device has a limited area to slide and thus restricting the opening of a paper clip at a certain distance thereby making it undesirable to grip larger paper bundle.",
