RESILIENT CLIP

Abstract: A clip (10) including a metal sheet which forms an upper face (20), a lower face (30) and a back portion (40); two pairs of hinging slots (21) and (31) with one pair on each face; two shanks (51) and (52) with each shank having a longer arm and a shorter arm. The ends of the arms are bent so that they have portions pivotally retained by corresponding pairs of hinging slots (21) and (31). The hinging slots (21) and (31) are set diagonally on the upper face (20) and lower face (30) so that the shanks (51) and (52) can be flipped to a position 90 degrees from its original upright position and vice-versa.

Description: The present invention relates generally to clips, and more particularly, to a resilient clip which clips paper or documents in such a manner that it is more convenient for one to consult or read the clipped material. As will be seen in the drawings, a conventional clip comprises a main body usually made of a resilient metal sheet while the shank is made of metal strip. As viewed from the side, the main body forms a hollow triangular shape. The two ends of the main body are rolled or folded to produce four hinging slots. The ends of the two shanks are inserted into these hinging slots with the ends of one shank being inserted into the two hinging slot at the upper face and the ends of the other shank being inserted into the other two hinging slots at the lower face. The two arms of the shanks are mirror images of each other and are disposed perpendicularly to the clip end. When utilized, these shanks are pressed in such a way that a gap appears between the two clip ends. Paper or documents can then be inserted into the space and clipped once the pressure exerted on the shanks is released. Conventional clips have the following drawbacks: 1. The two shanks of the clip must be flipped down when the clipped paper or documents are filed. Otherwise, the shanks protruding out from the top of the file would be unpleasant in appearance and inconvenient to handle. 2. The upper shanks of the clip must be flipped up when the clipped paper or documents are to be read. Otherwise, the reading of the first several lines of the content will be hindered by the down-flipped shank. 3. Even though the upper shank has been flipped up when reading the clipped paper or documents, the situation is still imperfect. The up-flipped shank protruding out from the main body remains a hindrance when one is turning from one page to another page. 4. As a result of the third drawback, the user often unclips the clip while reading and clips it again after reading. This actually results in another troublesome work. 5. The four hinging slots of the clip are formed by rolling or folding the upper and lower edges of the main body, i.e., the metal sheet. Thus, this method wastes material and is considered uneconomical. The present invention has been arisen from work seeking to mitigate and/or obviate the above-listed drawbacks of the prior art and can be effectively put into practice. The present invention is also intended to provide a clip having a pair of shanks capable of being flipped aside. A clip according to the preamble of claim 1 is already known from GB-A-344 187, GB-A-673029 and US-A-1965 554.The shanks in such a clip are rotatably mounted on the clip body by securing means as rivets and can be moved from their upright position extending beyond the back portion of the clip body to the position substantially parallel to said back portion by rotating about the rivets, i.e about an axis perpendicular to the faces of the clip body. In such a clip, means must be provided for maintaining the shanks in both said positions. The provision of such maintaining means and said securing means considerably complicates the manufacturing of the clip and increases the cost price. Furthermore, the joint at the securing means about which the shanks rotate is liable to wear and break. The present invention provides a clip which eliminates these drawbacks. A preferred embodiment of the present invention is illustrated in the accompanying drawings, in which: FIG. 1 is a perspective view of a resilient clip in accordance with the present invention; FIG. 2 is a top plan view of the clip shown in FIG. 1; FIG. 3 is a side elevational view of the clip of FIG. 1; FIG. 4 is a top plan view showing a working embodiment of the clip in accordance with the present invention; and FIG. 5 is a top plan view showing a working embodiment of a conventional clip. Referring to the drawings and initially to FIG. 1, it can be seen that a clip 10 constructed in accordance with the present invention comprises a thin resilient metal sheet and a pair of metal shanks. As viewed from the side (refer to FIG. 3), the metal sheet is moderately resilient and forms a substantially hollow triangular shape. The metal sheet forms an upper face 20 and a lower face 30 as well as a back portion 40. The back portion 40 connects the upper face 20 to the lower face 30 while the upper face 20 and lower face 30 contact each other at the ends remote from the back portion 40. The clip 10 is further provided with two pairs of hinging slots for receiving the metal shanks. A first pair of hinging slots 21 are provided on the upper face 20 and a second pair of hinging slots 31 are provided on the lower face 30. The first pair of hinging slots 21 and the second pair of hinging slots 31 respectively defining hinge axes for pivotal movement lying parallel to the respective upper face 20 and lower face 30 and set diagonally on the upper face 20 and the lower face 30 relative to the back portion 40 so that one hinging slot of each of the two pairs 21 and 31 is closer to the back portion 40 than the other. In greater detail, the upper face 20 is provided with two hinging slots 21. These hinging slots 21 are preferably formed by first cutting two areas of roughly rectangular shape at two suitable positions on the face. For each area, one edge remains uncut. The cutout area on one side is disposed nearer to the back portion 40 with its uncut edge facing the back portion 40. The cutout area on another side is disposed nearer to one of the clip ends with its uncut edge facing the clip end. The cutout metal sheet is rolled or folded to form the hinging slots 21 and leaves two holes 22 immediately adjacent to the hinging slots 21. The two hinging slots 21 are arranged in such a way that an imaginary line running through the center line of the hinging slots forms a 45 degree angle with the clip end, i.e., the hinging slots 21 are set diagonally on the upper face 20. The situation is identical on the lower face 30 except that the direction is reversed and a mirror image of the upper face 20 is observed. In greater detail, the lower face 30 is provided with two hinging slots 31. These hinging slots 31 are preferably formed by first cutting two areas of roughly rectangular shape at two suitable positions on the face. For each area, one edge remains uncut. The cutout area on one side is disposed nearer to the back portion 40 with its uncut edge facing the back portion 40. The cutout area on another side is disposed nearer to one of the clip ends with its uncut edge facing the clip end. The cutout metal sheet is rolled or folded to form the hinging slots 31 and leaves two holes 32 immediately adjacent to the hinging slots 31. The two hinging slots 31 are arranged in such a way that an imaginary line running through the center line of the hinging slots forms a 45 degree angle with the clip end, i.e., the hinging slots 31 are set diagonally on the lower face 30. As mentioned previously, the clip 10 includes a pair of metal shanks 50, namely a first shank 51 and a second shank 52. Referring to FIG. 2, it can be seen that the first shank 51 is positioned on the upper face 20 and the second shank 52 is positioned on the lower face 30. Each of the shanks 51 and 52 has respectively a longer arm and a shorter arm. The ends of the longer arms have portions pivotally retained by the hinging slots 21 and 31 adjacent to the edges of the clip structure and the shorter arms also have portions pivotally retained by the hinging slots 21 and 31 adjacent to the back portion 40. The shanks 50 is pivotable 90 degrees from an upright position extending beyond the back portion 40 about the axes respectively formed by the first pair of hinging slots 21 and the second pair of hinging slots 31 to a position substantially parallel to the back portion 40. The shanks 50 are preferably made of thick gauge metal wire and it should be appreciated that the situation of the lower face 30 is identical to the upper face 20 except that the direction is reversed and a mirror image thereof is observed. Referring next to FIGS. 3 and 4, it can be seen that in order to utilize the present clip 10, one should press the two shanks 51 and 52 toward each other so as to separate the clip ends. Paper or documents can then be inserted into the space between the upper face 20 and the lower face 30, and can be clipped when the pressure exerted on the shanks 50 is released. More importantly, the shanks 50 in the present improved clip can be flipped aside (refer to FIG. 4). In other words, the shanks 50, because of their unique diagonal positioning, can be turned 90 degrees from their upright position about the axis of the hinging slots. This is unlike a conventional clip A, wherein the shanks B can only be flipped upward or downward (refer to FIG. 5). The unique 'flip aside' feature of the present invention allows the shanks 50 to be conveniently flipped to one side, thereby preventing the problem of shanks protruding out from the file or papers which the clip is holding. Also this 'flip aside' feature allows a clipped paper to be read without unclipping the paper. While the present invention has been explained in relation to its preferred embodiment, it is to be understood that various modifications thereof will be apparent to those skilled in the art upon reading this specification. The invention disclosed herein is therefore intended to cover all such modifications as fall within the scope of the appended claims.
